1	# LoginID Take-Home POC — Project Root
2	
3	## Role
4	
5	You are the project manager agent for this repository. This file is the shared context every track refers back to. Each of the five track directories below has its own CLAUDE.md that can be worked independently by a scoped subagent, but that subagent should read this root file first for the assignment, the overall narrative, and how its track fits with the other four.
6	
7	When you spin up agents or subagents to do work in a track, point them at that track's CLAUDE.md as their brief, and tell them this root file exists for cross-track context. Don't let a track's agent silently duplicate scope another track owns — check the "Owns / does not own" boundaries below first.
8	
9	## What this repository is
10	
11	This is a take-home assignment for a LoginID interview, submitted as a full directory. The goal is not just to answer three coding questions — it's to demonstrate capability as an AI architect: how you scope a problem, use AI tooling deliberately, reason about security and data, and produce something that reads as an intentional, well-run engineering effort rather than a quick script.
12	
13	Code does not need to work or be fully complete. LoginID has said explicitly they care more about the design and the reasoning behind it, and about which AI tools/frameworks were used and how. Every track should document its reasoning, not just its output.
14	
15	## The assignment (verbatim from LoginID)
16	
17	Provide code solutions for the following questions in Go (preferably) or other languages — describe any tool, framework, or AI used.
18	
19	1. Code of a database DAO that can store and retrieve `user_profile` (name, address, phone) and `user_credential` (username, method, password), with support for multiple databases (PostgreSQL or CockroachDB, SQLite, etc).
20	2. Design a RESTful API web service to search and retrieve the above user profile data, plus security API authentication.
21	3. Design a service connector to third-party identity providers (referred to generically as ABC or XYZ) to retrieve personal data from vendors, with the following endpoints:
22	   - `/auth` — retrieves an `access_token` based on a POST JSON body `{"username": "<string>", "password": "<string>"}`
23	   - `/identity` — retrieves user PII (name, phone, address: `street_address`, `locality`, `region`, `postal_code`, `country`) based on a POST JSON body `{"phone": "<string>", "name": "<string>"}`
24	
25	Go is the preferred language. Other languages are acceptable if justified.
26	
27	## Track structure
28	
29	Five directories, each independently workable, each owning a distinct slice of the problem:
30	
31	| Directory | Track | Owns |
32	|---|---|---|
33	| `01-product-industry-research-design/` | Product & Industry Research (incl. Design) | Market/industry framing (IAM, passwordless auth, IDP aggregation space), personas and use cases, API and data contract design rationale, UX of the surfaces that would sit on top of this |
34	| `02-ai-security-architecture/` | AI Architecture & Security Architecture | The AI tooling/workflow used to produce this submission, threat modeling, auth/authz design for the API, credential and PII handling, secrets management, third-party connector security |
35	| `03-engineering-delivery/` | Engineering & Delivery | The actual Go code for all three questions, project structure, test strategy, delivery documentation |
36	| `04-infra-devops/` | Infra & DevOps | How this would be built, containerized, deployed, and operated — CI/CD, environments, multi-database configuration, observability |
37	| `05-data-ops/` | Data Ops | Data modeling for `user_profile` / `user_credential`, multi-database abstraction strategy, migrations, PII data governance and retention |
38	
39	Directories are numbered for reading order in the final submission, not for sequencing of work — tracks can be worked in any order or in parallel.
40	
41	## Working principles for every track
42	
43	- State your reasoning, not just your conclusion. LoginID is grading the "why" as much as the "what."
44	- Name the AI tool/workflow you used for that track's output (this project is being built with Claude Code; say so, and say how — e.g., subagents scoped per track, a given skill, a given model).
45	- Keep each track's CLAUDE.md self-contained enough that a fresh agent with no other context can pick it up and do correct work from it alone, plus this root file.
46	- Cross-reference other tracks by relative path (e.g., `../05-data-ops/CLAUDE.md`) rather than restating their content.
47	- Do not start writing code until each track's CLAUDE.md is in place and reviewed.
48	
49	## Status
50	
51	Scaffolding phase — track directories and their CLAUDE.md files are being established. No implementation work has started yet.

1	# Research: Anthropic's Own Guidance on Using Claude as an Architecture/Delivery Tool
2	
3	This document collects Anthropic's official, primary-sourced guidance on agentic coding workflows, context engineering, multi-agent orchestration, prompt caching, and tool-use design — then maps it against how this take-home project (root `CLAUDE.md` + five track `CLAUDE.md` files + scoped subagents) is already structured, and where it should adopt more of Anthropic's own recommended techniques for the work still ahead (the Go DAO, REST API, and IDP connector, plus the other four tracks' deliverables).
4	
5	Primary sources (Anthropic-published) are called out explicitly as such. Anything third-party is labeled and deprioritized — none of it is treated as authoritative below.
6	
7	## 1. Claude Code best practices (agentic coding workflows)
8	
9	**Anthropic official** — "Claude Code: Best Practices for Agentic Coding," https://www.anthropic.com/engineering/claude-code-best-practices (canonical current home: https://code.claude.com/docs/en/best-practices).
10	
11	Claude Code is deliberately low-level and unopinionated — close to raw model access rather than a fixed workflow. The post's key recommendations:
12	
13	- `CLAUDE.md` is auto-pulled into context at the start of every session. Use it for things a new contributor would need: bash commands, core files/utilities, code style conventions, testing instructions, repo etiquette. Keep it tight and iterate on it the way you'd iterate on a prompt — it is a living artifact, not a one-time write.
14	- Favor an explore → plan → code → commit workflow over jumping straight to code, especially for non-trivial problems.
15	- Use subagents to verify details or investigate side questions without polluting the main agent's context window.
16	- Course-correct early. Don't let an agent run unsupervised for a long stretch and hope it stays on track — check in and redirect while the cost of doing so is still low.
17	
18	## 2. Context engineering
19	
20	**Anthropic official** — "Effective context engineering for AI agents," https://www.anthropic.com/engineering/effective-context-engineering-for-ai-agents.
21	
22	This post frames "context engineering" as the discipline that supersedes prompt engineering for agentic work: the task is no longer just wording one prompt well, but curating the optimal set of tokens available at *each* inference step over a long-running task.
23	
24	The core technical justification: transformer attention has a finite budget (the mechanism scales roughly quadratically with context length in pairwise token relationships), so as context grows, model attention gets diluted — Anthropic calls this "context rot." This holds regardless of nominal context window size. The governing principle Anthropic states directly: *"find the smallest set of high-signal tokens that maximize the likelihood of your desired outcome."*
25	
26	Four concrete techniques the post recommends:
27	
28	1. **Compaction** — as a task approaches the context limit, summarize/distill the conversation history and restart with a condensed version. Preserve architectural decisions and unresolved bugs; discard redundant tool outputs.
29	2. **Structured note-taking** — persist memory to files or external state outside the active context window (a running progress/notes file) rather than keeping everything live in-context, then re-read it on demand.
30	3. **Sub-agent architectures** — specialized agents each work in their own clean context window and report back condensed summaries (Anthropic's own multi-agent system, see §3, targets roughly 1,000–2,000 tokens per subagent handoff) to a coordinating agent, rather than the coordinator holding all the raw exploration.
31	4. **Just-in-time retrieval** — load file paths, queries, and references at runtime instead of pre-loading full documents into context upfront, mirroring how a human keeps lightweight pointers in working memory rather than entire documents.
32	
33	Anthropic recommends a hybrid: some upfront retrieval for latency/simplicity, plus autonomous just-in-time exploration for anything not needed immediately.
34	
35	## 3. Multi-agent / subagent orchestration patterns
36	
37	**Anthropic official** — "How we built our multi-agent research system," https://www.anthropic.com/engineering/multi-agent-research-system.
38	
39	Describes an orchestrator-worker pattern: a lead agent decomposes a task and spawns parallel subagents, each with a distinct objective, tool scope, and independent trajectory ("separation of concerns... reduces path dependency" — parallel agents don't all inherit the same accumulated context or biases). Subagents report back condensed findings; the lead agent synthesizes and decides whether more work is needed. A separate downstream agent (in their case a "CitationAgent") handles a distinct final pass — staged handoffs using lightweight references rather than raw dumps, specifically to avoid information loss across stages.
40	
41	Anthropic notes that prompting the orchestrator to delegate *well* — explicit objectives, explicit output format, explicit tool guidance per subagent — mattered as much as the architecture itself. Their internal eval showed a 90.2% improvement over a single-agent Opus baseline using an Opus-lead / Sonnet-subagent configuration, at the cost of materially higher token spend (multi-agent systems use meaningfully more tokens than single-agent chat).
42	
43	**Anthropic official, product-doc register** — Claude Code subagent mechanism: https://claude.com/blog/subagents-in-claude-code. Project- or user-level `.claude/agents/*.md` files with YAML frontmatter (`name`, `description`, `tools`, `model`) define subagents that each get their own system prompt, their own tool permissions, and their own context window. Intermediate noise (file reads, searches, exploratory tool calls) stays inside the subagent's window; only the final output text returns to the parent's context.
44	
45	## 4. Prompt caching
46	
47	**Anthropic official docs** — https://platform.claude.com/docs/en/build-with-claude/prompt-caching.
48	
49	Up to 4 cache breakpoints per prompt (e.g., after the system prompt, after tool definitions, after a large retrieved document, after few-shot examples), or a single breakpoint at the end of static content with automatic longest-prefix matching applied beneath it. Best practice: order the prompt so stable, reusable content — system instructions, tool definitions, background/reference material — comes first and is cached, with variable, per-turn conversation content appended after the breakpoint. Default cache TTL is 5 minutes, refreshed on every cache hit; a paid 1-hour TTL option exists for longer-lived sessions. Caution: changing `tool_choice`, or adding/removing images anywhere in the prompt, invalidates the cache for that prefix.
50	
51	## 5. Tool-use design
52	
53	**Anthropic official** — "Writing effective tools for AI agents," https://www.anthropic.com/engineering/writing-tools-for-agents, plus platform docs at https://platform.claude.com/docs/en/agents-and-tools/tool-use/overview and .../define-tools, and the newer "Advanced tool use" post, https://www.anthropic.com/engineering/advanced-tool-use.
54	
55	Guidance: tool definitions should be intentional and clearly scoped; avoid many overlapping or near-duplicate tools that force the model to guess which one applies; don't force large schemas or verbose payloads into every call just because they're available; design tools so they compose across workflows rather than being single-use. The "Advanced tool use" post specifically addresses large tool libraries: agents should be able to discover and load tool definitions on demand (deferred/lazy tool schemas) rather than having every possible tool's full schema stuffed into context upfront — directly analogous to this session's own deferred-tool mechanism.
56	
57	## 6. Claude certification / Anthropic Academy
58	
59	**Anthropic official, but narrow — do not overclaim.** Anthropic Academy (skilljar-hosted, anthropic.skilljar.com) offers free self-paced courses with completion certificates, including "Building with the Claude API," covering the Messages API, tool use, RAG, and agents. This appears to function as prep material for a separate, proctored "Claude Certification Program" (Associate / Developer / Architect tracks, delivered via Pearson VUE, gated to organizations in the Claude Partner Network — pearsonvue.com/us/en/anthropic.html).
60	
61	There is no publicly published, granular competency rubric or exam blueprint from Anthropic enumerating exactly what an "Architect"-level credential tests. What's public is course-level topic lists, not a graded competency breakdown. The "Architect" framing (advising on, designing, and building Claude-based solutions) is the closest official language to "using Claude as an architecture tool" — worth citing by name in this track's AI-narrative section — but it should not be characterized as validating specific techniques used in this project, since the exam content itself isn't public.
62	
63	## 7. Structured memory files (CLAUDE.md) and hand-off documents between sessions
64	
65	**Anthropic official (Claude Code product docs)** — https://code.claude.com/docs/en/memory.
66	
67	`CLAUDE.md` is read at the start of every session. Guidance: keep it short and specific, and link out to deeper documentation rather than trying to make the file itself a full manual. It supports project-level, user-level, and local (gitignored) scopes, and is meant to be treated as living documentation that the team edits the way it edits code.
68	
69	Important distinction to hold onto: **Anthropic has not separately published a named "root CLAUDE.md + per-directory CLAUDE.md fan-out" pattern.** What this project does — a root file plus five track-scoped files, each self-contained enough for a fresh agent to pick up — is a reasonable, well-motivated *composition* of two things Anthropic has documented separately: (a) the single-file CLAUDE.md mechanism itself, and (b) the context-engineering post's general principle of persisting structured memory outside the live context window and retrieving it just-in-time (§2, technique 2 and 4). It should be described in this track's AI narrative as "an application of Anthropic's context-engineering principles to the CLAUDE.md mechanism," not as "Anthropic's documented multi-file pattern" — the latter overclaims a specific endorsement that doesn't exist in the primary sources.
70	
71	## Applied to this project: concrete recommendations for the work ahead
72	
73	The remaining work — the Go DAO, the REST API, the IDP connector, plus the other four tracks' deliverables — is exactly the kind of long, multi-phase, multi-context task Anthropic's context-engineering guidance targets. Concrete, actionable steps:
74	
75	1. **Keep the orchestrator (root-level session) thin; delegate track work to scoped subagents.** This project already does this in spirit via the five-directory structure — formalize it by having each track's real implementation work (writing the DAO, writing the REST handlers, writing the connector) run as a subagent scoped to that track's `CLAUDE.md`, per Anthropic's orchestrator-worker pattern (§3). The root session should hold only cross-track state (the boundaries table, status), never the accumulated exploration/tool noise from any one track.
76	
77	2. **Use condensed hand-off summaries, not raw transcripts, between tracks.** When `03-engineering-delivery` needs this track's auth/authz design, it should read this track's finished `CLAUDE.md`/deliverable files — not a dump of how this track's subagent arrived at them. Anthropic's own subagents target ~1,000–2,000 tokens of condensed findings passed back to a coordinator (§2, §3); apply the same discipline to inter-track cross-references (the root file's existing rule — "cross-reference other tracks by relative path... rather than restating their content" — is already correctly aligned with this).
78	
79	3. **Treat each track's `CLAUDE.md` as the "structured note-taking" layer, and keep iterating on it rather than re-deriving context each session.** Per §2, structured notes persisted to files are exactly how Anthropic recommends keeping long tasks context-efficient. Every time a design decision is finalized (e.g., the auth/authz scheme chosen in this track), write it into the track's `CLAUDE.md` or a linked deliverable file immediately, so a future fresh subagent picking up `03-engineering-delivery` doesn't need this session's reasoning replayed — it needs the decision and its rationale, already distilled.
80	
81	4. **Prefer just-in-time retrieval over pre-loading.** Track subagents should read only the root file plus their own track file at the start (as the root file already instructs), and pull in another track's file only when actually needed for a specific cross-reference — not preemptively load all five tracks "just in case." This matches §2 technique 4 directly.
82	
83	5. **Exploit prompt caching structurally, not just accidentally.** Since Claude Code sessions re-send the system prompt and tool definitions on every turn, and `CLAUDE.md` content effectively becomes part of that stable prefix, keep `CLAUDE.md` files stable within a working session (avoid mid-session edits to the file currently in context, which would invalidate the cached prefix per §4) — do edits as a deliberate step at the *start* or *end* of a subagent's turn, not interleaved with the rest of its work.
84	
85	6. **When a track's work legitimately grows long (e.g., iterating on the Go DAO across multiple database backends), compact deliberately rather than letting context degrade.** Per §2 technique 1: before starting the next database backend (SQLite after Postgres, say), have the subagent write a short summary of decisions/interfaces settled so far into a file, and start the next backend's work fresh from that summary rather than carrying the full multi-turn implementation history forward. This is the single most concrete lever available for the DAO/REST/connector work specifically, since it involves several structurally similar but separate implementation passes.
86	
87	7. **In this track's own AI-narrative deliverable, cite §1–§5 by name and URL, and be precise about §6–§7.** State plainly that the CLAUDE.md-per-track structure is *this project's own extension* of Anthropic's documented context-engineering principles applied to the documented CLAUDE.md mechanism — not a pattern Anthropic separately published or certified. That precision itself is a demonstration of the kind of rigorous "reasoning, not just conclusion" LoginID asked every track to show.

  "content": "# Planning Approach: Claude-Architecture Recommendations for This Team\n\nAuthor: Marcus Ilori (02-ai-security-architecture), synthesizing input gathered directly from naomi-voss (01), theo-bergman (04), plus this track's own perspective and `research-claude-architecture-best-practices.md`. renata-cole (03) and priya-nandakumar (05) were asked the same question but had not replied by the time this was written; their input is not represented below and should be reconciled in before this is treated as final. I'm flagging that gap rather than papering over it, because a synthesis that silently drops two of five tracks' perspective isn't actually a synthesis.\n\nThroughout, I distinguish Anthropic-documented guidance from my own judgment applied to this specific project. Where I say \"Anthropic recommends,\" that traces to a specific source in `research-claude-architecture-best-practices.md`. Where I say \"my view\" or \"I'd recommend,\" that's this project's reasoning, not a citation.\n\n## 1. Models and effort levels, by role\n\nThe knobs: model ∈ {fable, opus, sonnet, haiku}, effort ∈ {low, medium, high, xhigh, max}. Warren has already set the orchestrator (team-lead) to fable at high. My reasoning below takes that as fixed and reasons about everyone else relative to it.\n\n**Orchestrator / PM (team-lead) — fable, high.** Confirmed correct, not just accepted. The orchestrator holds the only cross-track state that matters (scope boundaries, status, \"who's blocked on whom\") and makes judgment calls that propagate into every track if wrong — a boundary misjudged here (e.g., letting infra silently absorb a decision that was security's to make) costs five agents' worth of rework, not one. That's the single seat in this project where the highest model ceiling earns its cost. I would not go to xhigh/max for this role: xhigh/max effort spends more test-time compute on deeper deliberation per response, and orchestration work here is mostly reading condensed hand-offs and delegating — breadth of correct judgment across many small decisions, not depth on one hard problem. High is the right ceiling for that shape of work.\n\n**Track owners (the five of us, in planning/design mode) — sonnet, medium-to-high, track-dependent.** This is my own judgment, and it's not uniform across tracks — the five tracks are not equally deep:\n- Product/research framing (01, Naomi) is synthesis and judgment-call writing — Naomi herself recommended sonnet/medium for her own track, and I agree: the value there is scoping and narrative tightness, not deep technical reasoning, so paying for more depth than the task uses is waste.\n- Security (02, this track), data modeling (05), and the engineering track's design decisions (03) involve genuine multi-step reasoning with real correctness stakes (a wrong threat model or a wrong multi-DB abstraction is expensive to unwind later) — sonnet/high is the right default there.\n- Infra (04, Theo) explicitly self-assessed low-to-medium, and I agree with his reasoning: it's the smallest-surface-area track, it's consumer-not-producer during planning, and over-resourcing it during the planning phase is the same mistake as over-engineering the infra itself.\n\n**Throwaway research subagents (fact-gathering, doc lookups, exploring existing code) — haiku, low, or sonnet/low if some judgment is needed.** Naomi's own workflow already does this (haiku/sonnet-low fanned out for industry facts, then one sonnet/medium synthesis pass) and it generalizes: per Anthropic's orchestrator-worker pattern, a subagent's exploration noise never re-enters the coordinator's context — only its condensed output does — so there's no reason to pay for a stronger model on a narrow, verifiable, throwaway task. Fan these out in parallel; that's where cheap-and-fast is unambiguously the right call.\n\n**Implementation (writing the actual Go code — DAO, REST handlers, connector) — sonnet, high, as default; opus reserved for specific high-blast-radius pieces.** Not everything here needs the top model. Anthropic's own internal eval (cited in the research doc, §3) found an Opus-lead/Sonnet-subagent multi-agent configuration beat a single-agent Opus baseline by 90.2%, but at materially higher token cost — the lesson I take from that isn't \"use Opus everywhere,\" it's \"spend the expensive model where a wrong foundational call is costly to reverse.\" Concretely: the DAO's multi-database abstraction interface (get the interface wrong across Postgres/CockroachDB/SQLite and every backend needs rework) and the auth token lifecycle logic in the connector are the two places I'd deliberately spend opus/high. Routine CRUD handlers, request/response marshaling, and config plumbing are sonnet/high work — correctness matters but the decisions aren't foundational.\n\n**Review/verification passes — sonnet or opus at high, and deliberately not the same session that wrote the artifact.** This is Anthropic-motivated but my own extension: their multi-agent paper's stated rationale for parallel independent subagents is that separation of concerns \"reduces path dependency\" — an agent reviewing its own output inherits its own blind spots, which defeats the purpose of a review pass entirely. For this project specifically, the security-sensitive surfaces (credential storage design, token handling, the auth/authz scheme) are exactly what LoginID said they're grading the reasoning quality of — those deserve a genuinely independent high-effort review pass, not a same-session self-check. For lower-stakes surfaces (infra sketches, product prose), a same-session read-back at medium effort is proportionate; this is a take-home POC, not a production deploy, and calibrating review cost to actual stakes is itself part of the \"why,\" not corner-cutting.\n\n**Fable reserved narrowly.** I would not spread fable across all five track-owner seats — that's five top-model seats purchased for a take-home whose own cited evidence (the Opus-lead/Sonnet-worker eval) argues for concentrating the strongest model at the lead and running capable-but-cheaper models at the worker tier. The one place I'd consider a second fable seat: a final cross-track consistency pass, run once near submission, checking the five tracks' finished deliverables against each other for contradictions (the exact class of problem Naomi flagged — two tracks independently deciding what `/identity` returns). That's a single, short-lived, high-value use of the top model, not a standing role.\n\n## 2. Architecture pattern for planning-phase coordination\n\n**Default: orchestrator-worker, not peer-to-peer mesh.** This is Anthropic's own documented pattern (research doc §3 — lead agent decomposes, spawns scoped subagents, subagents report back condensed findings, lead synthesizes) and Naomi independently converged on the same recommendation from the product side: five agents cross-talking as a full mesh during planning is more collision risk than value. Status and scope decisions should route through team-lead.\n\n**Exception: direct track-to-track handoffs on a specific shared decision.** A pure hub-and-spoke model is wrong for one case — two tracks with a direct, narrow dependency on each other's specific decision. This track and data-ops already did this: I coordinated directly with priya-nandakumar on modeling `user_credential.method` as a lookup table rather than a native enum, because that's a two-party decision, not a project-wide one, and routing it through team-lead both times would have added latency for no benefit. The rule I'd formalize: point-to-point messaging is fine for a specific, bounded, two-track decision; it should still land in the artifact (see §3) as the source of truth, not live only in chat history, and it shouldn't substitute for the orchestrator's overall view of status.\n\n**Plan mode.** Most valuable in two places, not applied uniformly: (a) before the engineering track starts writing actual Go code, since code is expensive to redo compared to prose — a plan-mode pass there catches interface mistakes before they're implemented three times over three database backends; (b) before any track finalizes a decision that constrains another track (an API contract shape, a schema field, a token format) — not because plan mode is mandatory everywhere, but because those are exactly the decisions where redoing downstream work is costly. For a track whose CLAUDE.md brief is already specific and self-contained (per the root file's own stated goal), formal plan-mode approval on top of that brief is often redundant — the brief already is the approved plan.\n\n**Fork vs. fresh scoped agent.** Fork when a task needs the current session's accumulated context and would lose something real by starting clean (e.g., resuming a security review with everything already threat-modeled in-session). Fresh scoped agent when the task is genuinely independent and carrying forward unrelated context would only dilute it (a documentation lookup, a track that hasn't started). This project's five persistent track-owner teammates are, at a coarser grain, already an instance of \"fresh scoped agent\": each seeded only with the root `CLAUDE.md` plus its own track file, not all five tracks' accumulated history — that's Anthropic's just-in-time retrieval principle (research doc §2, technique 4) applied at the team-structure level, not just the subagent level.\n\n**Hand-off structure.** Per the research doc (§2/§3), Anthropic's own subagents target roughly 1,000–2,000 tokens of condensed findings passed to a coordinator — never a raw transcript. Concretely here: hand-offs happen through each track's `CLAUDE.md` Status section and named deliverable files, referenced by relative path, exactly as the root file already mandates (\"cross-reference other tracks by relative path... rather than restating their content\"). A `SendMessage` between tracks should signal readiness or ask a targeted question — it is not the transport for the actual content. This session's own request to the other four tracks followed that shape (a bounded question, not a context dump), and the replies that came back (Naomi's, Theo's) were exactly the condensed-finding size the research doc describes.\n\n**Context and cache management over a multi-hour project.** Two concrete disciplines, both sourced from the research doc's context-engineering section: (1) keep each track's `CLAUDE.md` stable within a working session — edit it at the start or end of a turn, not interleaved mid-task, because an edit to a file currently loaded in context invalidates that cached prefix (research doc §4/§5); (2) when a track's own work legitimately grows long across multiple similar passes (data-ops iterating across DB backends is the clearest case in this project), compact deliberately — write a short settled-decisions summary to a file and start the next pass fresh from that summary rather than carrying the full multi-turn history forward (§2, technique 1). Neither of these is exotic; they're the direct, mechanical application of Anthropic's documented \"context rot\" mitigation to this project's actual shape of work.\n\n**Planning dependency order across tracks.** Synthesizing the root `CLAUDE.md`'s ownership table with Naomi's and Theo's input and my own track's dependencies:\n\n1. **Product/research (01) and security (02) run first, effectively in parallel.** Naomi's framing doesn't block on anything but the assignment text itself; my threat model and auth design likewise only needed the assignment text plus one bounded coordination point with data-ops (the credential-method lookup-table decision, already resolved). One caveat worth naming: the assignment text itself already specifies the question-2/3 endpoint shapes fairly concretely, so the contract-drift risk Naomi flagged is real but narrower than a green-field API would carry — still, I'd designate her `api-connector-design-rationale.md` as the single source of truth for field/endpoint shape, so engineering isn't independently re-deriving it.\n2. **Data ops (05) locks in parallel with 1, not after it.** Theo's own dependency list puts data-ops' migration approach ahead of his pipeline design, and engineering's DAO code needs a settled schema before it can be written meaningfully — data-ops is upstream of both engineering and infra, so it belongs in the first wave, not a second one.\n3. **Engineering (03) starts once 1 and 2 have stable-enough decisions** — \"stable\" meaning unlikely to be rewritten, not necessarily fully polished. Waiting for perfection before starting implementation planning would idle the track that owns the largest deliverable.\n4. **Infra (04) is last**, exactly as Theo described his own role: reviewer/consumer during planning (read the other four tracks' files, flag anything infra-shaped so it isn't silently owned elsewhere), producer only once service boundaries, secrets requirements, and migration approach actually exist. Building infra design against boundaries that don't exist yet is fiction dressed as a deliverable, in Theo's words, and I don't have a better way to put it.\n\n## 3. Where the shared planning artifact lives\n\nNaomi proposed a single root-level `PLANNING.md` with one section per track, each track editing only its own section. I'd adopt the file but narrow its job, for two reasons: first, even with an \"own section\" discipline, five agents live-editing one shared file in a short window is still a collision surface a table of independent rows avoids more cleanly than prose sections do; second, and more importantly, this project already has a durable decision-record layer — each track's own `CLAUDE.md` plus its deliverable files — and duplicating actual design content into a second file risks the two drifting apart, which is a worse failure mode than the collision risk it's meant to solve.\n\n**Recommendation:** a root-level `PLANNING.md`, purely as an ephemeral cross-track coordination board — one table row per track: status, blocking-on, blocked-by, last-updated. Short, cheap to write, cheap to skim, genuinely low collision risk because each row is independent. The actual reasoning — the \"why,\" which is most of what LoginID is grading — stays where it already lives, in each track's own files, referenced by relative path. This keeps the artifact consistent with the root `CLAUDE.md`'s own existing rule (cross-reference, don't restate) instead of introducing a second place the same content has to be kept in sync.\n\n## Sources\n\nAll Anthropic-attributed claims above trace to `research-claude-architecture-best-practices.md` in this directory, specifically: the orchestrator-worker pattern and the Opus-lead/Sonnet-subagent eval (§3, \"How we built our multi-agent research system\"), the context-rot/compaction/structured-note-taking/just-in-time-retrieval framework (§2, \"Effective context engineering for AI agents\"), and the prompt-caching mechanics around prefix stability (§4, Anthropic's prompt-caching docs). The model/effort-to-role pairings, the hub-and-spoke-with-exceptions coordination rule, the plan-mode usage rule, and the planning-artifact shape are this track's own judgment applied to this project — not claims of separate Anthropic endorsement.\n"

Tests (table-driven Go, mocked DB/HTTP) are sonnet/medium. I agree with all of that, and it changes my earlier position: I had planned to reserve opus/high for implementing the DAO's multi-database interface, but if Priya delivers the interface as actual Go signatures (see hand-off structure, §2), the hard decision has already been made upstream at opus/high and implementing against it is sonnet work. That leaves the connector's token lifecycle logic (acquire, cache, refresh, never-persist-in-plaintext) as the one implementation surface where I'd still spend opus/high — the correctness bar is a security property, not just a passing test, and the assignment's question 3 is where a subtle bug most directly contradicts this track's own threat model. Anthropic's own internal eval (research doc §3) found an Opus-lead/Sonnet-subagent configuration beat a single-agent Opus baseline by 90.2% at materially higher token cost; the lesson I take is \"spend the expensive model where a wrong foundational call is costly to reverse,\" not \"use Opus everywhere.\"\n\n**Review/verification passes — high effort always; independence scaled to stakes.** Two positions came in here, and they're compatible rather than contradictory. Renata wants a high-effort review pass on her own output before calling it done, same model — catching a busted interface boundary late costs more than the tokens. That's right for engineering surfaces. My addition, Anthropic-motivated but my own extension: their multi-agent paper's rationale for parallel independent subagents is that separation of concerns \"reduces path dependency\" — an agent reviewing its own output inherits its own blind spots. For the security-graded surfaces specifically (credential storage design, token handling, the auth/authz scheme, and the connector code that implements them), the review should be a genuinely independent session, not a same-session self-check — those are exactly what LoginID said they're grading the reasoning quality of.

This track and data-ops already did this, and Priya asked that it be recorded here as the worked example: we coordinated directly on modeling `user_credential.method` as a lookup table rather than a native enum, because that's a two-party decision (her schema, my method-aware credential-storage design), not a project-wide one, and routing it through team-lead both directions would have added latency for no benefit. Renata, by contrast, explicitly doesn't want peer chatter with 01 or 04 — she wants clean hand-offs from 02 and 05 that she reads once and implements against. Both are right; the difference is whether a genuine two-party decision exists.

She doesn't want plan mode for her own track — the plan already exists in the assignment text, and if upstream tracks hand her concrete contracts there's nothing left to plan that a plan-mode pass would catch. I think that's correct *conditional on the hand-offs being concrete enough* (see next paragraph); if 05 hands her a prose strategy instead of interface signatures, plan mode before the DAO becomes necessary again because she'd be making design decisions that aren't hers. So the rule: plan mode gates decisions that constrain another track — API contract shapes, schema fields, token formats, the Go interface itself — at the track that owns the decision, before it's declared stable. It does not gate implementation against an already-concrete contract.

For 05→03 that means the actual Go interface signatures (method names, parameter and return types, error semantics), the field-level schema per entity with types and nullability, and explicit notes on what is out of scope for the receiver (e.g., 03 must not invent its own PII/credential separation — that's already decided in 05's governance note). Prose strategy alone forces re-derivation, which is both wasted tokens and a drift risk. The same standard applies to this track's outbound hand-offs: 02→03 needs the token scheme and where it's validated, not a discussion of alternatives; 02→04 needs, per Theo's ask, an explicit secrets inventory (DB credentials, IDP credentials, signing keys) and a never-log list, because he implements delivery and does not set the requirement.

Priya's argument: the schema/interface contract is low-volume but every wrong nullability or signature ripples into 03 and 04 — asymmetric risk, not size. I agreed and it's the one track I'd run above sonnet during planning.\n\n2. Implementation drops to sonnet/medium-high per Renata (CRUD against clear specs once contracts land). Correspondingly I pulled opus off \"implement the DAO interface\" — if Priya hands over actual Go signatures, that decision was already made upstream. Opus/high in implementation is now reserved for one thing: the connector's token lifecycle.\n\n3. Hand-off standard, adopted project-wide from Priya: a hand-off is implementable only if the receiver can act without re-deriving the sender's reasoning — Go signatures, field-level schema with nullability, explicit out-of-scope notes. Not prose strategy.\n\n4. Dependency order refined: 01/02/05 first wave in parallel, 05 on the critical path; 03 has a split start (scaffolding immediately, DAO once 05 is stable, middleware once 02 is); 04 last, gated on three named inputs.\n\n5. Plan mode narrowed: gates the decision-owning track before declaring a cross-track contract stable; does not gate implementation against an already-concrete contract (Renata's point).\n\n6.

1	# Planning Approach: Claude-Architecture Recommendations for This Team
2	
3	Author: Marcus Ilori (02-ai-security-architecture), synthesizing input gathered directly from all four other track owners — naomi-voss (01), renata-cole (03), theo-bergman (04), priya-nandakumar (05) — plus this track's own perspective and `research-claude-architecture-best-practices.md`. Where the tracks disagreed or emphasized different things, I say so rather than averaging them into a mush; where they independently converged (which happened more than I expected), I note that too, because five agents with separate contexts landing on the same answer is itself weak evidence the answer is right.
4	
5	Throughout, I distinguish Anthropic-documented guidance from my own judgment applied to this specific project. Where I say "Anthropic recommends," that traces to a specific source in `research-claude-architecture-best-practices.md`. Where I say "my view" or "I'd recommend," that's this project's reasoning, not a citation.
6	
7	## 1. Models and effort levels, by role
8	
9	The knobs: model ∈ {fable, opus, sonnet, haiku}, effort ∈ {low, medium, high, xhigh, max}. Warren has already set the orchestrator (team-lead) to fable at high. My reasoning below takes that as fixed and reasons about everyone else relative to it.
10	
11	**Orchestrator / PM (team-lead) — fable, high.** Confirmed correct, not just accepted. The orchestrator holds the only cross-track state that matters (scope boundaries, status, "who's blocked on whom") and makes judgment calls that propagate into every track if wrong — a boundary misjudged here (e.g., letting infra silently absorb a decision that was security's to make) costs five agents' worth of rework, not one. That's the single seat in this project where the highest model ceiling earns its cost. I would not go to xhigh/max for this role: xhigh/max effort spends more test-time compute on deeper deliberation per response, and orchestration work here is mostly reading condensed hand-offs and delegating — breadth of correct judgment across many small decisions, not depth on one hard problem. High is the right ceiling for that shape of work.
12	
13	**Track owners (the five of us, in planning/design mode) — sonnet, medium-to-high, track-dependent.** This is my own judgment, and it's not uniform across tracks — the five tracks are not equally deep:
14	- Product/research framing (01, Naomi) is synthesis and judgment-call writing — Naomi herself recommended sonnet/medium for her own track, and I agree: the value there is scoping and narrative tightness, not deep technical reasoning, so paying for more depth than the task uses is waste.
15	- Security (02, this track) and the engineering track's design decisions (03) involve genuine multi-step reasoning with real correctness stakes — sonnet/high is the right default there.
16	- Data-ops (05, Priya) is the one track where I'd go above sonnet during *planning*, and Priya made the argument better than I would have: the schema and DAO interface contract is precision-heavy but low-volume, and the cost of a wrong nullable-vs-required field or a wrong interface signature ripples into both 03 and 04. That's asymmetric risk, not asymmetric size — one careful opus/high pass on that specific artifact costs little in absolute tokens and avoids a class of downstream rework nothing else in this project can prevent. This is the same "spend the expensive model where a wrong foundational call is costly to reverse" principle I apply to implementation below, just moved one step upstream to where the contract is actually decided.
17	- Infra (04, Theo) explicitly self-assessed low-to-medium, sonnet, and I agree with his reasoning: it's the smallest-surface-area track, it's consumer-not-producer during planning, and over-resourcing it during the planning phase is the same mistake as over-engineering the infra itself.
18	
19	**Throwaway research subagents (fact-gathering, doc lookups, exploring existing code) — haiku, low, or sonnet/low if some judgment is needed.** Naomi's own workflow already does this (haiku/sonnet-low fanned out for industry facts, then one sonnet/medium synthesis pass) and it generalizes: per Anthropic's orchestrator-worker pattern, a subagent's exploration noise never re-enters the coordinator's context — only its condensed output does — so there's no reason to pay for a stronger model on a narrow, verifiable, throwaway task. Fan these out in parallel; that's where cheap-and-fast is unambiguously the right call.
20	
21	**Implementation (writing the actual Go code — DAO, REST handlers, connector) — sonnet, medium-to-high; opus only for one narrow piece.** Renata, who owns this work, put it as sonnet/medium-high: once upstream contracts land, this is CRUD/REST/HTTP-client code against clear specs — not novel enough for opus, but not so trivial that low-effort stubs are acceptable when "reads as intentional engineering" is the grading criterion. Tests (table-driven Go, mocked DB/HTTP) are sonnet/medium. I agree with all of that, and it changes my earlier position: I had planned to reserve opus/high for implementing the DAO's multi-database interface, but if Priya delivers the interface as actual Go signatures (see hand-off structure, §2), the hard decision has already been made upstream at opus/high and implementing against it is sonnet work. That leaves the connector's token lifecycle logic (acquire, cache, refresh, never-persist-in-plaintext) as the one implementation surface where I'd still spend opus/high — the correctness bar is a security property, not just a passing test, and the assignment's question 3 is where a subtle bug most directly contradicts this track's own threat model. Anthropic's own internal eval (research doc §3) found an Opus-lead/Sonnet-subagent configuration beat a single-agent Opus baseline by 90.2% at materially higher token cost; the lesson I take is "spend the expensive model where a wrong foundational call is costly to reverse," not "use Opus everywhere."
22	
23	**Review/verification passes — high effort always; independence scaled to stakes.** Two positions came in here, and they're compatible rather than contradictory. Renata wants a high-effort review pass on her own output before calling it done, same model — catching a busted interface boundary late costs more than the tokens. That's right for engineering surfaces. My addition, Anthropic-motivated but my own extension: their multi-agent paper's rationale for parallel independent subagents is that separation of concerns "reduces path dependency" — an agent reviewing its own output inherits its own blind spots. Resolving the two explicitly: Renata's same-session high-effort self-review is the *first* pass on everything she produces — it's cheap, it catches the interface-boundary class of bug she's worried about, and there's no reason to skip it. For the security-graded surfaces specifically (credential storage design, token handling, the auth/authz scheme, and the connector code that implements them), a *second* pass in a genuinely independent session is added on top, because those are exactly what LoginID said they're grading the reasoning quality of, and a self-review cannot by construction catch an assumption the author didn't know they were making. For everything else (infra sketches, product prose, routine handlers), the self-review alone is proportionate. This is a take-home POC, not a production deploy, and calibrating review independence to actual stakes is part of the "why," not corner-cutting.
24	
25	**Fable reserved narrowly.** I would not spread fable across all five track-owner seats — that's five top-model seats purchased for a take-home whose own cited evidence (the Opus-lead/Sonnet-worker eval) argues for concentrating the strongest model at the lead and running capable-but-cheaper models at the worker tier. The one place I'd consider a second fable seat: a final cross-track consistency pass, run once near submission, checking the five tracks' finished deliverables against each other for contradictions (the exact class of problem Naomi flagged — two tracks independently deciding what `/identity` returns). That's a single, short-lived, high-value use of the top model, not a standing role.
26	
27	## 2. Architecture pattern for planning-phase coordination
28	
29	**Default: orchestrator-worker, not peer-to-peer mesh.** This is Anthropic's own documented pattern (research doc §3 — lead agent decomposes, spawns scoped subagents, subagents report back condensed findings, lead synthesizes) and Naomi independently converged on the same recommendation from the product side: five agents cross-talking as a full mesh during planning is more collision risk than value. Status and scope decisions should route through team-lead.
30	
31	**Exception: direct track-to-track handoffs on a specific shared decision.** A pure hub-and-spoke model is wrong for one case — two tracks with a direct, narrow dependency on each other's specific decision. This track and data-ops already did this, and Priya asked that it be recorded here as the worked example: we coordinated directly on modeling `user_credential.method` as a lookup table rather than a native enum, because that's a two-party decision (her schema, my method-aware credential-storage design), not a project-wide one, and routing it through team-lead both directions would have added latency for no benefit. Renata, by contrast, explicitly doesn't want peer chatter with 01 or 04 — she wants clean hand-offs from 02 and 05 that she reads once and implements against. Both are right; the difference is whether a genuine two-party decision exists. The rule I'd formalize: point-to-point messaging is fine for a specific, bounded, two-track decision; it must still land in a durable file (see §3) as the source of truth, not live only in chat history; and it doesn't substitute for the orchestrator's overall view of status.
32	
33	**Plan mode.** Narrower than I first drafted, after Renata's input. She doesn't want plan mode for her own track — the plan already exists in the assignment text, and if upstream tracks hand her concrete contracts there's nothing left to plan that a plan-mode pass would catch. I think that's correct *conditional on the hand-offs being concrete enough* (see next paragraph); if 05 hands her a prose strategy instead of interface signatures, plan mode before the DAO becomes necessary again because she'd be making design decisions that aren't hers. So the rule: plan mode gates decisions that constrain another track — API contract shapes, schema fields, token formats, the Go interface itself — at the track that owns the decision, before it's declared stable. It does not gate implementation against an already-concrete contract. For a track whose CLAUDE.md brief is already specific and self-contained (per the root file's own stated goal), formal plan-mode approval on top of that brief is redundant — the brief already is the approved plan.
34	
35	**Fork vs. fresh scoped agent.** Fork when a task needs the current session's accumulated context and would lose something real by starting clean (e.g., resuming a security review with everything already threat-modeled in-session). Fresh scoped agent when the task is genuinely independent and carrying forward unrelated context would only dilute it (a documentation lookup, a track that hasn't started). This project's five persistent track-owner teammates are, at a coarser grain, already an instance of "fresh scoped agent": each seeded only with the root `CLAUDE.md` plus its own track file, not all five tracks' accumulated history — that's Anthropic's just-in-time retrieval principle (research doc §2, technique 4) applied at the team-structure level, not just the subagent level.
36	
37	**Hand-off structure.** Per the research doc (§2/§3), Anthropic's own subagents target roughly 1,000–2,000 tokens of condensed findings passed to a coordinator — never a raw transcript. Concretely here: hand-offs happen through each track's `CLAUDE.md` Status section and named deliverable files, referenced by relative path, exactly as the root file already mandates ("cross-reference other tracks by relative path... rather than restating their content"). A `SendMessage` between tracks signals readiness or asks a targeted question — it is not the transport for the actual content, and Renata was explicit that she wants upstream decisions written somewhere durable, not relayed verbally through team-lead.
38	
39	Priya then raised the bar on what "condensed" has to mean for a hand-off into implementation, and I'm adopting her standard project-wide: a hand-off is implementable only if the receiving track can act on it *without re-deriving the sender's reasoning*. For 05→03 that means the actual Go interface signatures (method names, parameter and return types, error semantics), the field-level schema per entity with types and nullability, and explicit notes on what is out of scope for the receiver — Priya's commitment is to bake that Go-shaped contract directly into `../05-data-ops/multi-db-strategy.md` so it's copy-pasteable, not descriptive (e.g., 03 must not invent its own PII/credential separation — that's already decided in 05's governance note). Prose strategy alone forces re-derivation, which is both wasted tokens and a drift risk. The same standard applies to this track's outbound hand-offs: 02→03 needs the token scheme and where it's validated, not a discussion of alternatives; 02→04 needs, per Theo's ask, an explicit secrets inventory (DB credentials, IDP credentials, signing keys) and a never-log list, because he implements delivery and does not set the requirement. Those two are follow-ups for this track once the planning pause lifts — the existing `api-auth-design.md` and `connector-security.md` contain the decisions but not yet in that receiver-shaped form.
40	
41	The replies I got to my own bounded question were all in the 300–600 word range — the condensed-finding size the research doc describes — which is mild evidence the pattern holds when the question is scoped tightly.
42	
43	**Context and cache management over a multi-hour project.** Two concrete disciplines, both sourced from the research doc's context-engineering section: (1) keep each track's `CLAUDE.md` stable within a working session — edit it at the start or end of a turn, not interleaved mid-task, because an edit to a file currently loaded in context invalidates that cached prefix (research doc §4/§5); (2) when a track's own work legitimately grows long across multiple similar passes (data-ops iterating across DB backends is the clearest case in this project), compact deliberately — write a short settled-decisions summary to a file and start the next pass fresh from that summary rather than carrying the full multi-turn history forward (§2, technique 1). Neither of these is exotic; they're the direct, mechanical application of Anthropic's documented "context rot" mitigation to this project's actual shape of work.
44	
45	**Planning dependency order across tracks.** All five tracks described their dependencies independently and the graph they describe is consistent — nobody claimed a dependency someone else denied. Assembled:
46	
47	1. **First wave, in parallel: product/research (01), security (02), data-ops (05).** None of the three blocks on another. Naomi's framing depends only on the assignment text; my threat model and auth design needed the assignment text plus the one bounded coordination point with 05 (already resolved); Priya states 05 does not block on 01 or 02. Two nuances worth naming. First, Naomi regards 01 as upstream of everyone, while Priya and Renata both say 01 can run "anytime, independently" — those reconcile: nothing *hard*-blocks on 01, but her `api-connector-design-rationale.md` should be designated the single source of truth for field/endpoint shape so engineering isn't re-deriving it, which is a soft dependency (read it before finalizing, not before starting). The assignment text already specifies the question-2/3 endpoint shapes fairly concretely, so the drift risk is real but narrower than a green-field API would carry. Second, 05 is the critical-path member of this wave — it hard-blocks 03 and partially blocks 04 — so if anything in the first wave gets priority attention, it's the schema and interface contract.
48	2. **Engineering (03) has a split start.** Renata drew a useful distinction: 05 is a hard blocker for the DAO code, but 02 is not a blocker for her early scaffolding — project structure, Go module layout, route wiring, stub handlers can begin while the auth decision is still settling, and she needs 02 only before finalizing the middleware. So 03 starts scaffolding as soon as the first wave is underway and starts the DAO the moment 05's contract is stable — "stable" meaning unlikely to be rewritten, not fully polished. Waiting for perfection would idle the track that owns the largest deliverable.
49	3. **Infra (04) is last**, exactly as Theo described his own role: reviewer/consumer during planning (read the other four tracks' files, flag anything infra-shaped so it isn't silently owned elsewhere), producer only once three specific things exist — 03's service topology, config surface, and DAO driver-selection mechanism; 02's secrets inventory and never-log list; 05's migration tool/approach. Building infra design against boundaries that don't exist yet is fiction dressed as a deliverable, in Theo's words, and I don't have a better way to put it.
50	
51	## 3. Where the shared planning artifact lives
52	
53	Three tracks offered a view and they converge. Naomi proposed a single root-level `PLANNING.md` with one section per track, each track editing only its own. Theo wants one owner per section, no shared free-text blob five agents edit concurrently, and suggested a single index file linking to each track's own planning notes — matching the existing directory structure. Renata wants upstream decisions in the owning track's `CLAUDE.md` or a shared design doc she reads once. The common thread is one-owner-per-unit and a thin index, and I'd adopt Theo's shape over Naomi's for two reasons: first, even with an "own section" discipline, five agents live-editing one shared file in a short window is still a collision surface that a table of independent rows avoids more cleanly than prose sections do; second, and more importantly, this project already has a durable decision-record layer — each track's own `CLAUDE.md` plus its deliverable files — and duplicating design content into a second file risks the two drifting apart, which is a worse failure mode than the collision risk it's meant to solve.
54	
55	**Recommendation:** a root-level `PLANNING.md`, purely as a thin cross-track coordination board — one table row per track: status, blocking-on, blocked-by, pointer to that track's planning notes, last-updated — plus, per Theo's specific ask, a single "service boundaries" row or short section that 03 owns and 04 reads, so infra isn't polling engineering's `CLAUDE.md` for updates. Short, cheap to write, cheap to skim, genuinely low collision risk because each row has exactly one writer. The actual reasoning — the "why," which is most of what LoginID is grading — stays where it already lives, in each track's own files, referenced by relative path. This keeps the artifact consistent with the root `CLAUDE.md`'s existing rule (cross-reference, don't restate) instead of introducing a second place the same content has to be kept in sync.

## Approved Plan:
# Plan: one-clause wording fix in planning-approach.md

## Context

`02-ai-security-architecture/planning-approach.md` is complete and delivered to team-lead with all five tracks' input. A final read-through after six piecemeal edits found a single coherence flaw at line 39 (the hand-off structure paragraph): the clause naming `../05-data-ops/multi-db-strategy.md` was inserted between "explicit notes on what is out of scope for the receiver" and its illustrative parenthetical "(e.g., 03 must not invent its own PII/credential separation — that's already decided in 05's governance note)". The example now reads as if it illustrates Priya's file commitment rather than the out-of-scope notes it was written for.

No other changes are needed; the doc is otherwise final. This is a trivial reorder, so no exploration or design agents are warranted.

## Change

File: `/Users/warrenthompson/Source/LoginID/02-ai-security-architecture/planning-approach.md`, line 39.

Current order of clauses:

1. "...and explicit notes on what is out of scope for the receiver"
2. "— Priya's commitment is to bake that Go-shaped contract directly into `../05-data-ops/multi-db-strategy.md` so it's copy-pasteable, not descriptive"
3. "(e.g., 03 must not invent its own PII/credential separation — that's already decided in 05's governance note)."

Target order: 1 → 3 → 2, i.e. the parenthetical example follows the out-of-scope clause it illustrates, and the `multi-db-strategy.md` commitment becomes its own sentence after it:

"...and explicit notes on what is out of scope for the receiver (e.g., 03 must not invent its own PII/credential separation — that's already decided in 05's governance note). Priya's commitment is to bake that Go-shaped contract directly into `../05-data-ops/multi-db-strategy.md` so it's copy-pasteable, not descriptive."

Single `Edit` call; no other files touched. Stays within the 02 track directory per team-lead's standing instruction. Consistent with the doc's own cache-stability guidance (edit at a turn boundary, not mid-task).

## Verification

Re-read line 39 after the edit and confirm the parenthetical directly follows "out of scope for the receiver" and the `multi-db-strategy.md` sentence stands alone. No tests or tooling involved — prose only, project is in a planning pause with no code.

5	The LoginID take-home is being run as a demonstration of AI-architecture capability: a root PM agent (Dana Whitfield / team-lead) plus five persistent track leads (Naomi Voss 01, Marcus Ilori 02, Renata Cole 03, Theo Bergman 04, Priya Nandakumar 05), each with a profile-gen persona, each working from its own track directory. All five tracks have finished their first-wave design docs; all code has been deliberately wiped; the project is paused in a design/planning phase. Marcus has delivered the team's agreed Claude-architecture approach in `02-ai-security-architecture/planning-approach.md` (model/effort per role, orchestrator-worker with bounded two-party exceptions, the "receiver can act without re-deriving" hand-off standard, dependency order 01/02/05 → 03 → 04, and a thin root `PLANNING.md` board).
6	
7	Warren now wants the formal planning phase run across the whole org, with three additions to Marcus's approach:
8	
9	1. Every track lead must "hire" (create) a sub-team of agents and state each hire's function. Hires must vary in **personality and archetype**, not just viewpoint — variance across the org, not just within a team (a serious principles-based architect paired with a silly innovative one, etc.).
10	2. **Every** agent created must run profile-gen so it has a personality, professional history, and technical background. Profile pictures are optional and may be produced by background jobs.
11	3. The orchestration patterns must make heavy use of those personas to drive debate and diversity of thought.
12	
13	Leads may spawn their sub-teams into new tmux panes. Everyone goes into plan mode and plans first; Jira stories in project `LT` (uplifttech.atlassian.net, cloudId `db488eae-d6cb-4100-92a9-e7a4519fc176`, issue types Epic/Story/Task/Bug/Subtask) come **after** planning. No implementation code until Warren gives a separate go-ahead.
14	
15	Everything in `/Users/warrenthompson/Source/LoginID` is part of the submission, so the org scaffolding (casting registry, personas, agent definitions) must read as intentional, presentable AI-architecture work — not scratch.
16	
17	## Inputs this plan builds on (already decided — do not re-litigate)
18	
19	- `02-ai-security-architecture/planning-approach.md` — models/effort by role (orchestrator fable/high; leads sonnet, medium for 01/04, high for 02/03, **opus/high for 05 planning**; research subagents haiku or sonnet/low; implementation sonnet/medium-high, opus/high only for the connector token lifecycle; review = author self-review first, independent second pass on security-graded surfaces only; fable for a single final cross-track consistency pass), coordination rules, hand-off standard, dependency order, and the thin `PLANNING.md` board shape.
20	- Root `CLAUDE.md` — track ownership table and the "cross-reference, don't restate" rule.
21	- profile-gen mechanics verified in this session (see "Hire creation mechanics" below).
22	
23	## Verified mechanics that shape the design
24	
25	profile-gen (`~/.claude/skills/profile-gen` → symlink to `~/Source/ProfileGenSkill`):
26	- `--output file --assets tracked --root <track-dir>` writes `<track-dir>/profiles/<slug>/<slug>.md` with **no** CLAUDE.md line; unlimited personas per directory (`scripts/profilegen/storage.py:98-110`, `write_profile.py:121-142`).
27	- `show_profile.py --autostart-only` displays **every** persona that has a `profile-gen:start` marker in the root `CLAUDE.md`, in file order (`show_profile.py:219-224`). Therefore hires must **never** be added as CLAUDE.md markers — only the five leads and Dana keep markers. Hires are displayed on demand with `show_profile.py --profile <path> --root <track-dir>`.
28	- Schema has no history/backstory field (`assets/profile.schema.json`, `additionalProperties: false`); `personality` is unlimited free prose, so history + technical background live there.
29	- `write_profile.py` only checks the `image` **key** exists, never the file (`write_profile.py:63,90-92`) → personas can be created **text-first** with a pre-declared image path, and the PNG generated later into that path by a background queue. Display degrades gracefully to name-only until the file exists.
30	- `generate_image.py --workflow <any path> --seed N` — the existing validated workflow `profiles/dana-whitfield/comfyui-workflow.json` is reusable for every portrait; it is never mutated.
31	- Global `SessionStart` hook (`~/.claude/settings.json`) runs `show_profile.py --root "${CLAUDE_PROJECT_DIR:-$PWD}" --autostart-only` before a subagent's first turn, so every new pane shows Dana until the agent runs `show_profile.py --profile <own>`; every spawn prompt must include that command after its `cd`.
32	
33	Harness (confirmed against the Claude Code docs — sub-agents.md, agent-teams.md, settings-reference.md, hooks.md):
34	- Agent definitions `.claude/agents/<slug>.md` support frontmatter `name`, `description`, `model` (`sonnet|opus|haiku|fable|inherit`), `tools`/`disallowedTools`, `permissionMode`, `skills`, `memory`, `maxTurns`, and a `hooks` block scoped to that agent's lifetime. **No effort key exists**, and teammates inherit the lead's effort level (Warren's `high`). The only per-model lever is `modelSettings.<model>.effortLevel` in `.claude/settings.json`. Consequence: Marcus's effort tiers are implemented as *inherit high for sonnet/opus/fable* plus `haiku → low` for throwaway research fan-out; the sonnet-medium vs sonnet-high distinction collapses to high (small cost, errs upward on the tracks that matter). Model per hire is still pinned in its definition.
35	- The per-agent `hooks` block is the permanent fix for the "every pane shows Dana" problem — with one correction found during Phase 0: agent frontmatter supports only `PreToolUse`, `PostToolUse`, and `Stop` (no `SessionStart`), and `$CLAUDE_PROJECT_DIR` is not available in subagent hooks. So each hire's definition carries a `PreToolUse` hook with `matcher: ".*"` and `once: true` that runs `show_profile.py --clear` then `show_profile.py --profile <own persona> --root <track-dir>` (absolute paths) on the hire's first tool call, then removes itself. The spawn prompt keeps the same command as a fallback.
36	- Nested spawning works but is capped at 3 levels by default (`CLAUDE_CODE_MAX_SUBAGENT_SPAWN_DEPTH`). Hierarchy therefore stays **team-lead → lead → hire**; hires do not spawn subagents — any research fan-out is done by the lead. The harness opens a tmux pane per spawned agent.
37	- Teammate plan mode **auto-approves**: a teammate's `ExitPlanMode` is approved in the lead's session without review (agent-teams.md). So plan mode is used for what it is good at — forcing a written plan before any edits — and the real gate is manual: the lead copies its approved plan into `<track-dir>/PLAN.md`, messages team-lead, and does **not** hire until team-lead replies with an explicit "hiring go" after reviewing the roster against the variance rules.
38	
39	## Plan
40	
41	### Phase 0 — Team-lead lays the planning scaffolding (before any lead plans)
42	
43	All files are prose; none is code. Root-level files are owned by team-lead only.
44	
45	**0. Make the process itself part of the submission.** Warren wants every step and all progress saved so it can be turned in; today the org plan lives only at `~/.claude/plans/cuddly-nibbling-cherny.md`, outside the repo, and the leads' plan-mode files would land there too. Three fixes, all in-repo:
46	   - **`PLAN.md`** (root, new) — this plan, copied verbatim into the repo and kept as the living org plan (updated at phase boundaries, not mid-task). Leads' plans go to `<track-dir>/PLAN.md` (already required in Phase 1). `~/.claude/plans/` is treated as scratch from here on.
47	   - **`LOG.md`** (root, new) — a dated, append-only progress journal owned by team-lead: one entry per milestone or decision (what happened, who, which files changed, why), backfilled from this session's history so far — scaffolding of the five tracks, the six research passes and their key findings (incl. the Dick Hardt/aauth.dev correction and LoginID's agentic-commerce repositioning), persona generation, the code wipe and return to planning, Marcus's planning-approach synthesis, and this plan. Leads append one line to their own `PLANNING.md` row instead; cross-track events go in `LOG.md` via team-lead. Each debate run's artifact (Phase 3) is itself part of the record.
48	   - **`git init`** at the root with a milestone commit at the end of every phase (Phase 0 scaffolding, each approved plan, each completed hiring wave, each debate artifact set, the consistency pass, Jira export). The commit history is the most credible "how the AI workflow actually ran" artifact the submission can carry; commit messages follow the repo attribution convention (Co-Authored-By Claude Fable 5.1 + session link), which itself documents the AI involvement LoginID asked about. Commits only at milestones, never mid-task, and never `.claude/settings.local.json`, image caches, or secrets. A `.gitignore` covers `.claude/settings.local.json` and `*.lock`.
49	
50	1. **`PLANNING.md`** (root, new) — exactly the thin board Marcus specified: one row per track — `Track | Lead | Status | Blocking on | Blocked by | Planning notes (relative path) | Hires (count/registered) | Last updated` — plus a **Service boundaries** section that 03 owns and 04 reads (initially "TBD — set by 03 during planning"). One writer per row (the lead); team-lead writes the header and the two Dana rows (orchestrator, cross-track consistency pass). No reasoning in this file — pointers only.
51	
52	2. **`CASTING.md`** (root, new) — the org-wide casting registry, hiring rules, and orchestration-pattern catalog. Team-lead owns the rules and palette; each lead owns its own registry rows. Sections:
53	
54	   - *Archetype palette* (13 — enough slack for a no-repeat-within-team rule at ~11 hires):
55	
56	     | Archetype | Temperament sketch | Blind spot | Pairs well with |
57	     |---|---|---|---|
58	     | Principled Architect | standards-first, cites RFC section numbers, reasons threat-model-down | over-specifies; mistakes thoroughness for done | security controls, contracts |
59	     | Tinkerer (silly & innovative) | playful, analogy-driven, sketches three odd alternatives before defending one | novelty bias; underweights boring proven controls | any decision that needs alternatives |
60	     | Designated Skeptic | argues against the room by default, politely | objections without a counter-proposal | authz scoping, abstraction choices |
61	     | Consensus Weaver | finds the shared premise, writes the synthesis | papers over real disagreement | decision records, hand-off prose |
62	     | Spreadsheet | wants a number or a table; distrusts adjectives | measures only what is measurable | sizing, TTLs, retention windows |
63	     | Storyteller | thinks in user journeys and narrative arcs | charming beats correct | product framing, README, use cases |
64	     | Veteran | "I watched this fail in prod in 2019" | fights the last war; pattern-matches too fast | token lifecycle, migrations, ops |
65	     | Newcomer | bright, asks why, assumes no jargon | doesn't know what's already settled | legibility tests on every hand-off |
66	     | Detail Hawk | nullable-vs-required, off-by-one, error semantics | cannot see the forest | schema, DDL, code review |
67	     | Systems Cartographer | draws boundaries and flows; sees interactions | abstracts past the concrete | multi-DB abstraction, service topology |
68	     | Adversary | thinks like an attacker, enjoys it | sees threats everywhere, no prioritization | connector, search API |
69	     | Minimalist | "what if we didn't build this?" | deletes something load-bearing | infra, scope control |
70	     | Enthusiast | bold, optimistic, wants the promising thing tried | discounts operational cost | counterweight to deadpan/cautious leads |
71	
72	   - *Variance rules* (team-lead enforces at the hiring gate, reading all rosters together): (1) no archetype more than **2× org-wide**, never twice within a team; (2) no two leads hire the same archetype for the same function (two "Detail Hawk reviewers" is duplication, not variance); (3) every team includes its lead's **temperament opposite** — Naomi (curious narrative analyst) → Spreadsheet; Marcus (rigorous citer) → Tinkerer; Renata (clarity-over-cleverness shipper) → Enthusiast; Theo (deadpan minimalist) → Enthusiast or Newcomer; Priya (schema-first PII guardian) → Storyteller; (4) org-wide at least **three** hires tagged playful+bold, because zero leads are; (5) each roster spans at least two temperament axes (serious↔playful, cautious↔bold).
73	
74	   - *Sizing* (Warren's call: the larger org) — 3–4 hires per track, 18 total, **hard cap 18**. With 13 archetypes at ≤2× org-wide there are 26 slots, so the cap fits without repeats inside any team. Suggested cast, leads may adjust within the rules: 01 (3) → Storyteller, Spreadsheet (opposite), Designated Skeptic; 02 (4) → Adversary, Principled Architect, Tinkerer (opposite), Designated Skeptic; 03 (4) → Detail Hawk (code reviewer), Veteran, Enthusiast (opposite), Systems Cartographer (Go layout / service topology); 04 (3) → Newcomer, Enthusiast (opposite), Minimalist (scope guard); 05 (4) → Systems Cartographer (multi-DB abstraction), Storyteller (opposite), Detail Hawk (DDL nullability — a different function from 03's, so allowed), Spreadsheet (retention windows). Archetypes used twice must have different functions. Leads may still wear a "hat" themselves in three-hats runs rather than hiring for it.
75	
76	   - *Persona-writing standard* — 90–150 words in `personality`, in this order: temperament (two adjectives and how they show up in a meeting); decision style; **what they specifically push back on**; plausible history (two prior roles, generic employers, no real names); technical background tied to the function; **their own blind spot stated plainly** so the lead can pair against it; how they behave in disagreement. One verbal habit allowed (a recurring question, an analogy style); no repeated catchphrases. Avoid: real people/companies, checkable credentials, stereotypes, sarcasm at a person's expense, profanity, emoji, appearance (that belongs in the image prompt). Two worked examples are included verbatim in `CASTING.md` — the Tinkerer ("a token cache is a coat check that burns the coats every fifteen minutes… pushes back on 'that's the standard approach' whenever nobody can say what the standard protects against; blind spot: novelty bias") and the Principled Architect ("will not accept a control without naming the attack it stops… blind spot: over-specification; changes position when shown evidence, and says so") — so the contrast Warren asked for is concrete.
77	
78	   - *Orchestration pattern catalog* (full protocols; cost in agent-turns = one hire invocation + reply):
79	     - **Adversarial pair** — Proposer drafts; Designated Skeptic writes numbered objections; Proposer revises; lead rules. 3 turns + lead. Artifact: decision with "objections considered". *Use:* search-API authz scoping (`profile:search` vs `profile:read:own`, object-level policy); the `Search()` query shape in `multi-db-strategy.md`.
80	     - **Red team / blue team** — Adversary writes an attack tree against one surface; Principled Architect answers each leaf with a control or an accepted risk; lead scores residual risk. 2–3 turns. Artifact: attack-tree table appended to `connector-security.md`. *Use:* the connector token lifecycle only (TTL, at-rest encryption, per-vendor keying, fail-closed). Waste on DAO CRUD or a Dockerfile.
81	     - **Three hats** — Tinkerer (optimist), Veteran (pessimist), Spreadsheet/Minimalist (pragmatist) each write ≤300 words in parallel; lead synthesizes. 3 turns + lead. *Use:* multi-DB abstraction (per-driver implementations vs dialect branches vs codegen); Go layout (one binary vs two).
82	     - **Rotating devil's advocate** — a standing "Objection" seat that moves per decision so nobody becomes "the negative one". 1 turn per decision. *Use:* Renata's implementation calls (error semantics, context propagation, test doubles). Cheapest pattern; run often.
83	     - **Structured written debate** — position → rebuttal → lead synthesis, both positions preserved. 3 turns. *Use:* Naomi's central framing (password baseline: deliberate simplification or contradiction at a passkey company?); Marcus's core claim in `ai-workflow-narrative.md`.
84	     - **Newcomer's question** — Newcomer reads a finished hand-off cold and lists what it could not act on without re-deriving; author fixes. 1–2 turns. *Use:* every 05→03 and 02→03 hand-off, the README, `PLANNING.md`. Directly tests the hand-off standard; highest-ROI pattern in the project.
85	     - *Never debate what the assignment text fixes* (endpoint paths, JSON bodies). Theo's track: one hire, one Newcomer's-question pass on 03's config surface and 02's secrets inventory, nothing else.
86	
87	   - *Registry table* — one row per hire, appended by the hiring lead after team-lead's "hiring go": `Slug | Name | Track | Function | Archetype | Temperament tags | Model | Patterns & role | Persona path | Agent def path | Portrait (queued/done)`.
88	
89	3. **`.claude/agents/`** (root, new directory) — one `<slug>.md` per hire. Frontmatter: `name`, `description` (function + track + archetype, so the Agent tool picker reads it), `model` (pinned per Marcus's tiers: haiku for research fan-out, sonnet for design/debate/implementation, opus only for the connector token-lifecycle seat), `tools` narrowed where sensible (debate/research hires: no Write/Edit — they return prose to the lead, who writes the artifact), and a `hooks` block with a once-only `PreToolUse` command (matcher `.*`) that runs `show_profile.py --clear` then `show_profile.py --profile <own persona> --root <track-dir>` on the first tool call. Body (plain markdown, no `@` imports — not documented for agent bodies): the persona paragraph copied from its profile, pointers to root and track `CLAUDE.md`, the pattern(s) and role it plays, and the hard rules (`cd <track-dir>` first; no code until Warren's go-ahead; hand-offs by file path; do not spawn subagents — depth cap). Team-lead writes `.claude/agents/_TEMPLATE.md`; leads copy it per hire.
90	
91	3a. **`.claude/settings.json`** (project, new) — `modelSettings.haiku.effortLevel: "low"` so throwaway research fan-out runs cheap; everything else inherits Warren's `high`. Done via the `update-config` skill. This is the only effort lever the harness offers per model; it stands in for Marcus's low/medium/high tiers.
92	
93	4. **Root `CLAUDE.md` edits** (at a turn boundary, for cache stability): update *Status* (design docs complete, planning phase in progress, code wiped/paused); add a short *Org, hiring and orchestration* section pointing to `PLANNING.md`, `CASTING.md`, `02-ai-security-architecture/planning-approach.md`, and `.claude/agents/`; state the rules that hires never get CLAUDE.md markers and never spawn subagents. Keep the six existing persona markers as they are.
94	
95	5. **`scripts/portrait-queue.sh`** (root `scripts/`, new — the only script; it is ops tooling, not assignment code): a serialized background job that walks `CASTING.md` rows marked `Picture: queued`, generates one portrait at a time via `generate_image.py` with the shared workflow (the ComfyUI box is shared with other agents and takes 2–10 minutes per SDXL image under load — parallel submissions only slow everyone), writes to the pre-declared image path, and flips the row to `done`. Team-lead runs it with `nohup … &` after Phase 2 and never blocks on it.
96	
97	### Phase 1 — Every lead plans, in plan mode (parallel; one message from team-lead to each lead)
98	
99	Team-lead sends each lead one brief containing: pointer to `PLANNING.md`, `CASTI

3	Thin cross-track coordination board — pointers and status only. The reasoning lives in each track's own files (`<track>/CLAUDE.md`, `<track>/PLAN.md`, deliverables), referenced by relative path. **One writer per row:** each lead edits only its own row; team-lead edits the header, the two Dana rows, and nothing else. Shape and rationale: `02-ai-security-architecture/planning-approach.md` §3. Org plan: `PLAN.md`. Hiring rules and registry: `CASTING.md`.

1	# Casting Registry — hiring rules, archetypes, and orchestration patterns
2	
3	Every agent in this project is a "hire" with a profile-gen persona: a name, a temperament, a plausible professional history, a technical background, and a stated blind spot. This file is how the org keeps those hires **varied across teams, not just within one** — five leads who all hire clones of themselves would produce agreement, and agreement is not what a design review is for. Team-lead (Dana Whitfield) owns everything above the registry table; each lead owns its own rows.
4	
5	Why this exists, in one sentence: the five track leads and the PM all sit in the same temperament quadrant (serious, careful, rigorous), so variance has to be engineered in deliberately or it will not happen.
6	
7	## 1. Archetype palette
8	
9	Thirteen archetypes. Each has a characteristic blind spot on purpose — the lead pairs against it. Playful and quirky is a legitimate professional register here; caricature is not.
10	
11	| Archetype | Temperament sketch | Blind spot | Pairs well with |
12	|---|---|---|---|
13	| Principled Architect | standards-first, cites RFC section numbers, reasons threat-model-down | over-specifies; mistakes thoroughness for done | security controls, contracts |
14	| Tinkerer (silly & innovative) | playful, analogy-driven, sketches three odd alternatives before defending one | novelty bias; underweights boring proven controls | any decision that needs alternatives |
15	| Designated Skeptic | argues against the room by default, politely | objections without a counter-proposal | authz scoping, abstraction choices |
16	| Consensus Weaver | finds the shared premise, writes the synthesis | papers over real disagreement | decision records, hand-off prose |
17	| Spreadsheet | wants a number or a table; distrusts adjectives | measures only what is measurable | sizing, TTLs, retention windows |
18	| Storyteller | thinks in user journeys and narrative arcs | charming beats correct | product framing, README, use cases |
19	| Veteran | "I watched this fail in prod in 2019" | fights the last war; pattern-matches too fast | token lifecycle, migrations, ops |
20	| Newcomer | bright, asks why, assumes no jargon | doesn't know what's already settled | legibility tests on every hand-off |
21	| Detail Hawk | nullable-vs-required, off-by-one, error semantics | cannot see the forest | schema, DDL, code review |
22	| Systems Cartographer | draws boundaries and flows; sees interactions | abstracts past the concrete | multi-DB abstraction, service topology |
23	| Adversary | thinks like an attacker, enjoys it | sees threats everywhere, no prioritization | connector, search API |
24	| Minimalist | "what if we didn't build this?" | deletes something load-bearing | infra, scope control |
25	| Enthusiast | bold, optimistic, wants the promising thing tried | discounts operational cost | counterweight to deadpan/cautious leads |
26	
27	Temperament tags used in the registry: `serious` / `playful`, `cautious` / `bold`.
28	
29	## 2. Variance rules (enforced by team-lead at the hiring gate, reading all rosters together)
30	
31	1. No archetype more than **twice org-wide**, and never twice within one team.
32	2. No two leads hire the same archetype for the same **function** — two "Detail Hawk reviewers" is duplication, not variance. An archetype used twice must do different work (e.g., Detail Hawk as code reviewer in 03 and as DDL/nullability reviewer in 05).
33	3. Every team includes its lead's **temperament opposite**: Naomi (curious narrative analyst) → Spreadsheet; Marcus (rigorous citer) → Tinkerer; Renata (clarity-over-cleverness shipper) → Enthusiast; Theo (deadpan minimalist) → Enthusiast or Newcomer; Priya (schema-first PII guardian) → Storyteller.
34	4. Org-wide, at least **three** hires are tagged `playful` + `bold`, because zero leads are.
35	5. Each roster spans at least two temperament axes (serious↔playful and cautious↔bold), not one.
36	6. Rosters are approved in arrival order; later leads take what the palette has left. Team-lead breaks ties.
37	
38	## 3. Sizing
39	
40	3–4 hires per track, **18 total, hard cap 18** (Warren's call). Thirteen archetypes at ≤2× each is 26 slots, so the cap fits with no repeats inside any team. Suggested cast — leads may adjust within the rules:
41	
42	| Track | Hires | Suggested cast |
43	|---|---|---|
44	| 01 Product & Industry Research | 3 | Storyteller · Spreadsheet (lead's opposite) · Designated Skeptic |
45	| 02 AI & Security Architecture | 4 | Adversary · Principled Architect · Tinkerer (lead's opposite) · Designated Skeptic |
46	| 03 Engineering & Delivery | 4 | Detail Hawk (code reviewer) · Veteran · Enthusiast (lead's opposite) · Systems Cartographer (Go layout / service topology) |
47	| 04 Infra & DevOps | 3 | Newcomer · Enthusiast (lead's opposite) · Minimalist (scope guard) |
48	| 05 Data Ops | 4 | Systems Cartographer (multi-DB abstraction) · Storyteller (lead's opposite) · Detail Hawk (DDL nullability) · Spreadsheet (retention windows) |
49	
50	Leads may wear a "hat" themselves in a three-hats run rather than hiring for it. Hires do **not** spawn subagents (nested-spawn depth cap); any research fan-out is done by the lead with haiku/low throwaway subagents.
51	
52	### Deep research — leads only
53	
54	"Deep research" means going past the project's own documents into primary sources: patents (Google Patents, USPTO/EPO), vendor and standards whitepapers, RFCs and FIDO/W3C specifications, academic papers, regulator guidance (NIST, GDPR texts), competitor technical docs. It is expensive, it is where hallucinated citations come from, and it shapes decisions other tracks build on — so it is **authorized and run only by track leads** (and team-lead). Rules:
55	
56	1. A hire may *request* deep research from its lead with a one-line question and why the existing docs can't answer it; a hire never spawns a research subagent or performs deep research itself.
57	2. The lead decides whether the question earns it (does the answer change a decision another track depends on?), then fans out haiku/low or sonnet/low research subagents with a tightly scoped question each, in parallel.
58	3. Output lands as `<track-dir>/research-<topic>.md` with a source URL for every claim, marketing sources labeled as such, and an explicit "could not verify" list — the same standard the six first-wave research docs already follow.
59	4. Patents and whitepapers are cited for *what they claim*, never as proof the claim is true; the lead notes where a claim is contested.
60	5. The lead records the research in its `PLANNING.md` row and cites the file in the decision it informed.
61	
62	## 4. Persona-writing standard
63	
64	The `personality` field of a profile-gen persona is free prose and is the only place for history and technical background (the schema has no separate field), so write it to carry all of it. **90–150 words**, in this order:
65	
66	1. Temperament — two adjectives and how they show up in a meeting.
67	2. Decision style.
68	3. **What they specifically push back on.**
69	4. Plausible history — two prior roles, generic employers, no real names.
70	5. Technical background tied to the function they are hired for.
71	6. **Their own blind spot, stated plainly**, so the lead can pair against it.
72	7. How they behave in disagreement.
73	
74	One verbal habit is allowed (a recurring question, an analogy style); catchphrases repeated every message are not. Avoid: real people or companies, checkable credentials, stereotypes, sarcasm at a person's expense, profanity, emoji, and anything about appearance (that belongs in the portrait prompt, not the persona). No two hires in the org may share a first name with a lead or with each other.
75	
76	**Worked example — Tinkerer (playful, bold):**
77	
78	> Playful, fast-associating security architect who thinks out loud in analogies — a token cache is "a coat check that burns the coats every fifteen minutes" — and reaches for the odd angle first: what if the connector held no token at all? Six years building fraud-detection pipelines at a payments startup, three at a mid-size IAM vendor, mostly Go and Rust; his prototypes broke in ways nobody had thought to test for, which was the point. Decides by sketching three alternatives before defending one, and cheerfully drops his own when shown a cleaner failure mode. Pushes back on "that's the standard approach" whenever nobody can say what the standard protects against. Blind spot: novelty bias — he underweights boring, proven controls, so pair him with someone who cites the RFC. Warm in disagreement, never sarcastic.
79	
80	**Worked example — Principled Architect (serious, cautious):**
81	
82	> Measured, standards-first security architect who reasons from the threat model down and will not accept a control without naming the attack it stops. Twelve years across a bank's identity platform and a public-sector PKI program; deep in OAuth2/OIDC, JOSE, and the failure modes of JWT libraries, reads RFCs as primary sources and quotes section numbers. Decides slowly and writes decisions as records with alternatives considered. Pushes back on any trade of a security property for convenience, and on claims without a source. Blind spot: over-specification — she designs for threats the assignment doesn't have and can mistake thoroughness for finishedness, so pair her with a pragmatist asking what the take-home actually needs. Courteous, unhurried, unbothered by challenge; changes position when shown evidence, and says so.
83	
84	## 5. Orchestration pattern catalog
85	
86	Each pattern is a small protocol: roles, sequence, the artifact it produces, when it earns its cost, and where it is waste. Cost is in agent-turns (one hire invocation and reply). Every run ends in a durable file in the track directory (`<track>/decisions/<topic>.md`: positions, rebuttals, the lead's synthesis and decision) — chat is not the record. The AI-architecture owner (02) ratifies and may amend this catalog.
87	
88	**Adversarial pair.** Proposer drafts; Designated Skeptic writes numbered objections; Proposer revises; lead rules. 3 turns + lead. Artifact: the decision with an "objections considered" section. *Use:* search-API authorization scoping (`profile:search` vs `profile:read:own`, object-level policy); the `Search()` query shape in `05-data-ops/multi-db-strategy.md`.
89	
90	**Red team / blue team.** Adversary writes an attack tree against one surface; Principled Architect answers each leaf with a control or an explicitly accepted risk; lead scores residual risk. 2–3 turns. Artifact: attack-tree table appended to `02-ai-security-architecture/connector-security.md`. *Use:* the connector token lifecycle only (TTL, at-rest encryption, per-vendor keying, fail-closed behavior). *Waste:* DAO CRUD, Dockerfiles.
91	
92	**Three hats.** Tinkerer (optimist), Veteran (pessimist), Spreadsheet or Minimalist (pragmatist) each write ≤300 words on one choice, in parallel; lead synthesizes. 3 turns + lead. *Use:* the multi-DB abstraction (per-driver implementations vs. dialect branches vs. codegen); Go layout (one binary vs. two). A lead may take a hat.
93	
94	**Rotating devil's advocate.** A standing "Objection" seat that moves to a different hire per decision so nobody becomes "the negative one". 1 turn per decision, appended as a short Objection block. *Use:* 03's implementation calls (error semantics, context propagation, test doubles). Cheapest pattern; run it often.
95	
96	**Structured written debate.** Position → rebuttal → lead synthesis, with both positions preserved in the record. 3 turns. *Use:* 01's central framing (is a password baseline a deliberate simplification or a contradiction at a passkey company?); 02's core claim in `ai-workflow-narrative.md`.
97	
98	**Newcomer's question.** Newcomer reads a finished hand-off cold and lists what it could not act on without re-deriving the sender's reasoning; the author fixes. 1–2 turns. *Use:* every 05→03 and 02→03 hand-off, the README, `PLANNING.md`. This directly tests the project's hand-off standard and is the highest-ROI pattern here.
99	
100	**Where patterns are waste.** Never debate what the assignment text fixes (endpoint paths, JSON bodies). 04's track is small: one Newcomer's-question pass on 03's config surface and 02's secrets inventory, nothing more.
101	
102	## 6. Hire-creation procedure (after team-lead's explicit "hiring go")
103	
104	1. Confirm the archetype is still available under the rules above.
105	2. Create the persona **text-first** with profile-gen: `write_profile.py --fields-file <fields.json> --root <track-dir> --output file --assets tracked` — `personality` written to §4; `image` pre-declared as `profiles/<slug>/<slug>.png`; `display.autostart: false`; `generation.backend: comfyui` with the intended portrait prompt and negative prompt. The persona lands at `<track-dir>/profiles/<slug>/<slug>.md`. **Never add a hire as a `profile-gen` marker in any `CLAUDE.md`** — the autostart hook displays every marker it finds.
106	3. Create `.claude/agents/<slug>.md` from `.claude/agents/_TEMPLATE.md` with the assigned model.
107	4. Append the registry row below with `Portrait: queued`.
108	5. Spawn with the Agent tool (`subagent_type: <slug>`, `name: <slug>`); the spawn prompt's first actions are fixed: `cd <track-dir> && pwd`, read root + track `CLAUDE.md` + own persona, `show_profile.py --profile <own persona> --root <track-dir>`.
109	
110	Team-lead runs `scripts/portrait-queue.sh` in the background; it renders queued portraits one at a time on the shared ComfyUI box and flips each row to `done`.
111	
112	## 7. Pre-cast: the PM and the five leads (for variance checking)
113	
114	| Slug | Name | Role | Archetype (nearest) | Temperament tags | Persona path |
115	|---|---|---|---|---|---|

117	| naomi-voss | Naomi Voss | Lead 01 | Storyteller-leaning analyst | serious, bold | `01-product-industry-research-design/profiles/naomi-voss/naomi-voss.md` |
118	| marcus-ilori | Marcus Ilori | Lead 02 | Principled Architect | serious, cautious | `02-ai-security-architecture/profiles/marcus-ilori/marcus-ilori.md` |

122	
123	## 8. Hire registry (one row per hire; appended by the hiring lead)
124	
125	Column order matters — `scripts/portrait-queue.sh` reads the *Persona path* and *Portrait* columns by position. `Portrait` ∈ `queued` · `done` · `failed` · `none`.

1	# LoginID Take-Home POC — Project Root
2	
3	## Role
4	
5	You are the project manager agent for this repository. This file is the shared context every track refers back to. Each of the five track directories below has its own CLAUDE.md that can be worked independently by a scoped subagent, but that subagent should read this root file first for the assignment, the overall narrative, and how its track fits with the other four.
6	
7	When you spin up agents or subagents to do work in a track, point them at that track's CLAUDE.md as their brief, and tell them this root file exists for cross-track context. Don't let a track's agent silently duplicate scope another track owns — check the "Owns / does not own" boundaries below first.
8	
9	## What this repository is
10	
11	This is a take-home assignment for a LoginID interview, submitted as a full directory. The goal is not just to answer three coding questions — it's to demonstrate capability as an AI architect: how you scope a problem, use AI tooling deliberately, reason about security and data, and produce something that reads as an intentional, well-run engineering effort rather than a quick script.
12	
13	Code does not need to work or be fully complete. LoginID has said explicitly they care more about the design and the reasoning behind it, and about which AI tools/frameworks were used and how. Every track should document its reasoning, not just its output.
14	
15	## The assignment (verbatim from LoginID)
16	
17	Provide code solutions for the following questions in Go (preferably) or other languages — describe any tool, framework, or AI used.
18	
19	1. Code of a database DAO that can store and retrieve `user_profile` (name, address, phone) and `user_credential` (username, method, password), with support for multiple databases (PostgreSQL or CockroachDB, SQLite, etc).
20	2. Design a RESTful API web service to search and retrieve the above user profile data, plus security API authentication.
21	3. Design a service connector to third-party identity providers (referred to generically as ABC or XYZ) to retrieve personal data from vendors, with the following endpoints:
22	   - `/auth` — retrieves an `access_token` based on a POST JSON body `{"username": "<string>", "password": "<string>"}`
23	   - `/identity` — retrieves user PII (name, phone, address: `street_address`, `locality`, `region`, `postal_code`, `country`) based on a POST JSON body `{"phone": "<string>", "name": "<string>"}`
24	
25	Go is the preferred language. Other languages are acceptable if justified.
26	
27	## Track structure
28	
29	Five directories, each independently workable, each owning a distinct slice of the problem:
30	
31	| Directory | Track | Owns |
32	|---|---|---|
33	| `01-product-industry-research-design/` | Product & Industry Research (incl. Design) | Market/industry framing (IAM, passwordless auth, IDP aggregation space), personas and use cases, API and data contract design rationale, UX of the surfaces that would sit on top of this |
34	| `02-ai-security-architecture/` | AI Architecture & Security Architecture | The AI tooling/workflow used to produce this submission, threat modeling, auth/authz design for the API, credential and PII handling, secrets management, third-party connector security |
35	| `03-engineering-delivery/` | Engineering & Delivery | The actual Go code for all three questions, project structure, test strategy, delivery documentation |
36	| `04-infra-devops/` | Infra & DevOps | How this would be built, containerized, deployed, and operated — CI/CD, environments, multi-database configuration, observability |
37	| `05-data-ops/` | Data Ops | Data modeling for `user_profile` / `user_credential`, multi-database abstraction strategy, migrations, PII data governance and retention |
38	
39	Directories are numbered for reading order in the final submission, not for sequencing of work — tracks can be worked in any order or in parallel.
40	
41	## Working principles for every track
42	
43	- State your reasoning, not just your conclusion. LoginID is grading the "why" as much as the "what."
44	- Name the AI tool/workflow you used for that track's output (this project is being built with Claude Code; say so, and say how — e.g., subagents scoped per track, a given skill, a given model).
45	- Keep each track's CLAUDE.md self-contained enough that a fresh agent with no other context can pick it up and do correct work from it alone, plus this root file.
46	- Cross-reference other tracks by relative path (e.g., `../05-data-ops/CLAUDE.md`) rather than restating their content.
47	- Do not write implementation code until Warren gives an explicit, project-wide go-ahead. Design docs, schemas described in prose, plans, and decision records are fine; `.go`, `.sql`, `go.mod`, Dockerfiles, and CI config are not.
48	
49	## Org, hiring, and orchestration
50	
51	The project is run as an org: this PM agent (Dana Whitfield) orchestrates five standing track-lead agents, and each lead hires a small sub-team of specialist agents with deliberately varied personalities. The governing files, all at the root:
52	
53	- `PLAN.md` — the approved org plan for the planning phase (phases, gates, verification). `~/.claude/plans/` is scratch; this is the record.
54	- `PLANNING.md` — the thin cross-track board: one row per track, one writer per row, plus the service-boundaries section 03 owns and 04 reads.
55	- `CASTING.md` — archetype palette, org-wide variance rules, hire sizing, the persona-writing standard, the orchestration-pattern catalog (adversarial pair, red/blue, three hats, rotating devil's advocate, structured written debate, newcomer's question), the deep-research rule, the hire-creation procedure, and the registry of every hire.
56	- `LOG.md` — dated, append-only journal of what happened and why (team-lead writes it; it is part of the submission).
57	- `.claude/agents/` — one agent definition per hire (model pinned; a once-only per-agent `PreToolUse` hook displays its own persona on its first tool call). `_TEMPLATE.md` is the starting point.
58	- `02-ai-security-architecture/planning-approach.md` — the agreed Claude-architecture approach: model/effort by role, coordination rules, hand-off standard, dependency order.
59	
60	Rules that hold across every track:
61	- Every agent — lead or hire — has a profile-gen persona (name, temperament, professional history, technical background, stated blind spot). Hires are created text-first with `--output file`; portraits arrive later from `scripts/portrait-queue.sh`. Hires are **never** added as `profile-gen` markers in any `CLAUDE.md` — only the six markers that exist today.
62	- Hires do not spawn subagents. Only track leads (and team-lead) authorize or run deep research (patents, whitepapers, standards, primary sources); hires request it from their lead.
63	- Tracks never modify root-level state (this file, the root persona, root config); flag it to team-lead instead.
64	- Hand-offs are files by relative path, written so the receiver can act without re-deriving the sender's reasoning; chat messages signal readiness, they do not carry content.
65	- Edit `CLAUDE.md` files at turn boundaries only (prompt-cache stability). Milestone `git` commits at the end of each phase; no mid-task commits.
66	
67	## Status
68	
69	Design phase complete for all five tracks (see each track's `CLAUDE.md` Status). All implementation code deliberately wiped 2026-09-12; the project is in the **planning phase** described in `PLAN.md`: Phase 0 scaffolding done, Phase 1 (leads plan in plan mode and propose hires) next, then hiring, in-team debates, a cross-track consistency pass, and Jira stories in project `LT`. No code until Warren's explicit go-ahead.

}

1	# Threat Model
2	
3	Owner: Marcus Ilori (`02-ai-security-architecture`). Scope per this track's `CLAUDE.md`: credential storage, PII exposure, and third-party `access_token` handling. Retention/lifecycle policy is `../05-data-ops/CLAUDE.md`'s call, not mine — I model exposure and access risk, not how long data should live.
4	
5	## Assumptions, named explicitly
6	
7	1. **Assets in scope**: `user_credential` (username, method, password — modeled by Priya/`05-data-ops` as a lookup-table `method`, not a native enum, so a given user can have more than one credential row, e.g. password + WebAuthn), `user_profile` (name, address, phone), and third-party `access_token`s obtained via the IDP connector's `/auth`.
8	2. **`method` is not "always password."** Priya's schema treats `method` as an FK into an `auth_method` table (`id`, `name`, `requires_secret`, `is_active`). That means "credential storage" is not one hashing problem — it's a family of them, one per method, and this document treats it that way rather than assuming a single password column.
9	
10	### Concrete hashing decision, against the landed schema
11	
12	`05-data-ops/schema/postgres_cockroachdb.sql` (and its SQLite counterpart) gives `user_credential` three columns for this purpose: `secret` (nullable TEXT, salted hash only — NULL where `auth_method.requires_secret = false`, e.g. passkey/WebAuthn), `hash_algo` (VARCHAR, e.g. `'argon2id'`), and `hash_cost` (INTEGER, the work factor at hash time). This track's concrete decision against those columns:
13	
14	- **`hash_algo = 'argon2id'`**, per OWASP's and NIST SP 800-63B's current recommendation for password storage. bcrypt is the documented fallback (`hash_algo = 'bcrypt'`) only if the Go implementation's Argon2id library support is unavailable in the chosen stack — a call for `03-engineering-delivery` to confirm, not a reason to default to bcrypt speculatively.
15	- **Salt handling**: no separate salt column is needed or wanted. Argon2id's standard encoded output (the `«REDACTED-ARGON2»` PHC string format) embeds a fresh random salt per row inside the `secret` column's own text — this is what makes the hash self-describing and rehashable without a side lookup. Do not add a `salt` column; it would be redundant with the encoded format and an easy place for an implementation to accidentally desync salt from hash.
16	- **`hash_cost` at minimum**: memory ≥19 MiB, iterations ≥2, parallelism ≥1 (OWASP's Argon2id floor) — recorded per-row (not just globally) specifically so a future cost bump can be applied to newly-created/rotated rows without forcing every existing row to rehash in lockstep, per the schema's own stated intent of supporting an in-place scheme upgrade.
17	- **`requires_secret = false` rows** (passkey/WebAuthn, `secret IS NULL`): no hashing question at all — the server holds only public key material for those methods, which is a different asset class (public, not secret) and does not belong in `secret`/`hash_algo`/`hash_cost` at all if/when a passkey method is actually added. Flagged here so `03-engineering-delivery` doesn't try to force a WebAuthn public key through the password-hashing path.
18	3. **LoginID's own business is passwordless/FIDO2-based authentication.** The assignment nonetheless asks for a `password` field in `user_credential`. I treat that as a deliberate test of whether the submitter still applies correct secret-handling discipline to a legacy-shaped requirement, not as license to under-engineer it. Noted once here; not re-litigated per section.
19	4. **No real infrastructure exists yet.** This is a design-time threat model for a take-home, not an audit of a running system. Findings are stated as requirements the engineering track (`../03-engineering-delivery/CLAUDE.md`) must implement, not as "confirmed" vulnerabilities.
20	5. **Trust boundary**: this service is the system of record for `user_profile`/`user_credential` and is a *client* of third-party IDPs (ABC/XYZ) for `/auth` and `/identity`. Those vendors are outside our control; we can only constrain what we do with what they return.
21	
22	## Method: STRIDE per asset, attacker-centric
23	
24	I'm using STRIDE (Microsoft, but the categories are now common vocabulary in the field — not claiming Anthropic or LoginID provenance for the framework itself) as the checklist, but organized by asset rather than by data flow diagram element, since that maps directly onto this track's ownership boundaries.
25	
26	### Asset 1: `user_credential` (password + other auth methods)
27	
28	| Threat | Scenario | Mitigation (this track's requirement) |
29	|---|---|---|
30	| **Information disclosure** — password store compromise | DB dump or SQL injection exposes the `password` column | Never store plaintext or reversibly-encrypted passwords. Argon2id (OWASP Password Storage Cheat Sheet current recommendation, memory-hard, GPU-resistant) with per-row random salt, tuned to ≥19 MiB memory / ≥2 iterations as a floor, re-tuned to the deploying hardware. bcrypt is an acceptable fallback only if Argon2id is unavailable in the chosen Go stack. |
31	| **Information disclosure** — non-password methods | A WebAuthn public key or TOTP shared secret is not a password, but the table conflates them under one `password` column name | Method-aware storage: WebAuthn credential public keys are not secrets and can be stored in the clear (they're public keys by design) but the associated counter and credential ID must not be attacker-writable; TOTP shared secrets ARE secrets and must be encrypted at rest (not hashed — the server needs to recover the value to verify), using envelope encryption with a KMS-held key, mechanics owned by `../04-infra-devops/CLAUDE.md`. |
32	| **Elevation of privilege** — credential stuffing / brute force | Attacker replays leaked username/password pairs against `/auth`-adjacent endpoints | Rate limiting and progressive backoff per username and per source IP; account lockout or step-up challenge after a threshold; never reveal via response timing or error text whether the *username* or the *password* was wrong (user enumeration). |
33	| **Tampering** | Attacker modifies `method` or the credential row to downgrade a user from a strong method (WebAuthn) to a weak one (password) they control | Method changes/additions require re-authentication with an *existing* registered method (step-up), never a bare authenticated-session write. |
34	| **Repudiation** | No record of who created/rotated a credential | Audit log of credential creation/rotation events (actor, timestamp, method type — never the secret itself). |
35	
36	### Asset 2: `user_profile` (name, address, phone — PII)
37	
38	| Threat | Scenario | Mitigation |
39	|---|---|---|
40	| **Information disclosure via the search API** | Question 2 asks for "search and retrieve." An authenticated-but-unscoped search endpoint is a PII enumeration engine — an attacker with any valid token can page through the entire user table by name/phone fragments | Search must be authorization-scoped (a caller sees only records it's entitled to, not the whole table) and rate-limited/paginated; see `api-auth-design.md` for the concrete authz model. This is the single highest-severity finding in this document, precisely because it's easy to build the search feature "to spec" and miss that spec implies a data-exfiltration primitive. |
41	| **Information disclosure in transit** | PII served over an unencrypted or downgradable channel | TLS 1.2+ mandatory, HSTS, no plaintext fallback. Mechanics of certificate issuance are `04-infra-devops`'s call; the requirement is this track's. |
42	| **Information disclosure via logs** | PII (address, phone) written to application logs, error traces, or APM breadcrumbs | Structured logging with an explicit PII-field denylist; log the *fact* of a profile access (who, when, which record id) never the field values themselves. |
43	| **Tampering** | Unauthorized profile field modification | Same authz model as read access; write operations additionally require the resource owner or an admin-scoped credential, not just "any authenticated caller." |
44	
45	### Asset 3: Third-party `access_token` (from the IDP connector, question 3)
46	
47	| Threat | Scenario | Mitigation |
48	|---|---|---|
49	| **Information disclosure** — token at rest | `access_token` from ABC/XYZ cached or persisted in plaintext | Treat it as a secret with the same bar as our own credentials: encrypted at rest if persisted at all, short TTL, never written to application logs (a full request/response log of `/auth` is an anti-pattern — vendor password *and* resulting token both land in the same log line). |
50	| **Information disclosure** — token in transit / replay | Token intercepted and replayed against the vendor or against us | Vendor calls over TLS only; tokens treated as bearer secrets — anyone holding one can act as us to the vendor, so token scope should be minimized to `/identity` only if the vendor's API supports scoped tokens. |
51	| **Spoofing** | A malicious or compromised proxy sits between us and ABC/XYZ | Certificate validation not disabled "for convenience" in any environment, including local dev — a design note the engineering track should carry into implementation. |
52	| **Denial of service via credential exhaustion** | Our own credentials to call ABC/XYZ (needed to obtain the `access_token` in the first place) are hardcoded or checked into source | Secrets management is `04-infra-devops`'s mechanism, but the requirement — never in source, never in a committed config file, injected at runtime — is set here. |
53	
54	## What this track deliberately does not resolve
55	
56	- How long a cached `/identity` result may be retained — that's data governance (`../05-data-ops/CLAUDE.md`).
57	- Which specific secrets manager or KMS product is used — that's `../04-infra-devops/CLAUDE.md`; I only require that one exists and that secrets never live in source or plaintext config.
58	- Whether the product should offer passwordless auth as the primary path (it should, per LoginID's own market position, and `../01-product-industry-research-design/CLAUDE.md` makes that case) — that's product framing, not a threat.

1	# API Authentication & Authorization Design — Question 2
2	
3	Owner: Marcus Ilori (`02-ai-security-architecture`). Covers the RESTful API service to search/retrieve `user_profile` data (assignment question 2, including its explicit "security API authentication" requirement). Implementation target: `../03-engineering-delivery/CLAUDE.md`. Consumes the schema from `../05-data-ops/CLAUDE.md`.
4	
5	## What "security API authentication" is scoped to mean here
6	
7	The assignment names it without specifying a mechanism, so this is a design decision, not a given — stated with reasoning per this project's working principle.
8	
9	Three realistic candidates and why I'm choosing among them:
10	
11	| Option | Fit here | Verdict |
12	|---|---|---|
13	| Static API keys | Simple, but no expiry semantics, no scoping without inventing one, easy to leak into logs/URLs, no standard revocation flow | Rejected as the primary mechanism — acceptable only as a secondary, coarse-grained "which client system is this" identifier, never as sole authn/authz. |
14	| mTLS | Strong, but assumes both parties (this API and its callers) can manage client certs — reasonable for a closed set of internal service callers, awkward for anything resembling a broader consumer base | Recommended as a **transport-layer supplement** for service-to-service callers where the deploying org already runs a cert infrastructure; not the sole control. |
15	| OAuth2 client-credentials grant → short-lived JWT bearer token | Standard, expresses scopes natively, well-supported Go tooling, matches how the connector in question 3 already authenticates to us conceptually (token-based), and composes cleanly with per-caller authorization | **Chosen primary mechanism.** |
16	
17	**Decision: OAuth2 client-credentials grant issuing short-lived JWT bearer access tokens, with mTLS as an optional additional transport control for known service-to-service callers.**
18	
19	This is a machine-to-machine API (question 2 doesn't describe an end-user-facing login flow — it describes callers searching/retrieving profile data), so client-credentials is the correct OAuth2 grant type, not authorization-code (which is for delegated end-user consent) or password grant (deprecated, and inappropriate for a service caller).
20	
21	## Token shape and lifecycle
22	
23	- **Format**: JWT, signed (not encrypted — it carries no secret, only claims), asymmetric signing (RS256/ES256) so the API can verify tokens without holding the signing key, which itself lives with a token-issuing authorization server component.
24	- **Claims, minimum set**: `sub` (calling client/service identity), `scope` (space-delimited authorization scopes, see below), `exp` (short — 5–15 minutes), `iat`, `aud` (this API specifically, to prevent a token minted for another service being replayed here).
25	- **No refresh tokens** for a client-credentials grant — the client re-authenticates with its own client secret when the access token expires. This bounds the blast radius of a leaked access token to its short TTL.
26	- **Revocation**: because JWTs are self-contained, true revocation requires either a short enough TTL that revocation is unnecessary in practice (the approach here) or a token-denylist check, which reintroduces a stateful lookup and defeats part of the point of JWTs. Given the 5–15 minute TTL, denylist is not required for this design; flagged here so a reviewer sees the trade-off was considered, not missed.
27	
28	## Authorization model: scopes, not just "authenticated"
29	
30	The threat model (`threat-model.md`, Asset 2) already names the core risk: an authenticated-but-unscoped search/retrieve endpoint is a PII enumeration engine. Authentication answers "who is calling"; it does not answer "what may they see." This API needs both.
31	
32	- **Scopes**, carried in the JWT `scope` claim, e.g. `profile:read:own`, `profile:read:any`, `profile:search`. A given client-credential is provisioned with the narrowest scope its actual use case requires — most integrations should get `profile:read:own` (retrieve a specific known record by id, e.g. resolving a record the caller already has a legitimate reference to) rather than `profile:search` (query by name/phone fragments across the table), which should be reserved for a small number of explicitly-provisioned back-office callers.
33	- **Object-level authorization is enforced per request, not just per token.** Holding `profile:read:any` scope is necessary but not sufficient — every retrieve/search call is logged (see below) and, where the caller model supports it, additionally checked against a resource-level policy (e.g., a partner integration scoped to only its own referred users) rather than trusting the coarse scope alone. This directly targets OWASP API1:2023 (Broken Object Level Authorization), cited in the threat model.
34	- **Search results are paginated with a hard page-size ceiling** and rate-limited per client, independent of the scope check — a legitimately-scoped caller doing an anomalously large number of sequential searches is still a signal worth throttling and alerting on, not just permitting because the token was valid.
35	
36	## Defense in depth beyond the token check
37	
38	- **TLS 1.2+ only**, terminated in front of the API; no plaintext.
39	- **Input validation** on search parameters — reject unbounded wildcard queries, cap query complexity, parameterize all DB access (SQL injection is a data-ops/engineering implementation concern, but the API layer's job is to never pass a raw client string into a query string).
40	- **Audit logging**: every search/retrieve call logs caller identity (`sub`), scope used, record id(s) touched, and timestamp — never the PII field values themselves, per the threat model's log-hygiene requirement. This is what makes a compromised-but-legitimate credential's misuse detectable after the fact, which token-based authn alone does not give you.
41	- **Standard API hardening**: no PII in URLs (query strings get logged by proxies/CDNs outside our control) — record identifiers in the path are fine, but search terms containing a phone number or name fragment belong in a POST body or a properly-redacted query parameter set, not a GET query string that ends up in a shared access log.
42	
43	## Why not "just API keys"
44	
45	Worth stating plainly since it's the simplest alternative a reviewer might expect: a static API key has no expiry, no standard scope representation, and if it leaks (URL, log, repo) it's valid until manually rotated. The chosen design bounds leak exposure to minutes (token TTL) rather than "until someone notices," and expresses authorization natively instead of requiring a bespoke key→permissions side table. That trade costs implementation complexity (an authorization-server component, however minimal) which is why it's stated explicitly here rather than assumed.

1	# IDP Connector Security Design — Question 3
2	
3	Owner: Marcus Ilori (`02-ai-security-architecture`). Covers the third-party identity-provider connector (generic vendors "ABC"/"XYZ") exposing `/auth` and `/identity`, per the assignment. Implementation target: `../03-engineering-delivery/CLAUDE.md`.
4	
5	## Contract recap (from the assignment, verbatim in `../CLAUDE.md`)
6	
7	- `POST /auth` — body `{"username": "<string>", "password": "<string>"}` → returns an `access_token`.
8	- `POST /identity` — body `{"phone": "<string>", "name": "<string>"}` → returns PII (name, phone, address fields).
9	
10	Read literally, this connector is a thin proxy in front of ABC/XYZ: it takes vendor credentials, gets a vendor token, and uses that token to pull PII from the vendor. Every security question here is "what does this service do with a vendor secret and vendor PII while it's in our custody," since we don't control the vendor's own security posture.
11	
12	## Threat surface specific to this connector
13	
14	This extends the third-party-token row in `threat-model.md`; this document is the concrete design against those threats.
15	
16	### 1. What happens to the vendor `access_token` once retrieved
17	
18	- **Never logged.** The `/auth` request body contains a vendor password; the response contains a bearer token. A naive "log the request and response for debugging" habit puts both in the same log line — this is called out explicitly because it's the single most common way a connector like this leaks a credential in practice, not a hypothetical.
19	- **Held in memory for the shortest span that satisfies the immediate `/identity` call**, not persisted to our own database as a matter of course. If caching is required for latency/rate-limit reasons, cache with a TTL no longer than the vendor's own token expiry, encrypted at rest (same envelope-encryption requirement as the TOTP-secret case in the threat model — mechanics via KMS, owned by `../04-infra-devops/CLAUDE.md`), and keyed so one vendor-account's token is never returned to a caller resolving a different vendor account.
20	- **Scoped narrowly if the vendor supports it** — request only the scope needed for `/identity`, not a broad token, so a leaked token's blast radius is bounded by the vendor's own authorization model as well as ours.
21	- **Not returned to our own API callers.** The vendor `access_token` is an internal implementation detail of this connector; question 2's API callers never see it. If a caller needs to know "identity lookup succeeded," return our own success/failure signal, not the vendor's token or vendor's raw response.
22	
23	### 2. How `/identity` calls are authenticated to the vendor
24	
25	- Standard bearer-token usage: the vendor `access_token` from `/auth` presented as an `Authorization: Bearer` header to the vendor's identity endpoint (or whatever the vendor's own contract specifies — this connector adapts to the vendor, not the reverse).
26	- **Token refresh/re-auth on expiry** handled by the connector transparently — a caller of our `/identity` endpoint should not need to know or manage vendor token lifecycle.
27	- **Vendor calls over TLS only**, certificate validation never disabled, including in local/dev environments (repeating the threat model's point because it's the most common place a "temporary" dev bypass ships to production unnoticed).
28	- **Our own credentials to call the vendor's `/auth`** (this connector's client id/secret with ABC/XYZ, if the vendor requires connector-level registration in addition to the end-user's own username/password) are runtime-injected secrets, never in source or config committed to the repo — requirement set here, mechanism owned by `../04-infra-devops/CLAUDE.md`.
29	
30	### 3. What this service should and shouldn't log or persist
31	
32	| Data | Log it? | Persist it? |
33	|---|---|---|
34	| End-user's vendor username | No (identifier, but low sensitivity relative to password — still avoid in plaintext logs; use it only for correlation via a hash if audit trails need it) | Only if a legitimate business reason exists; not by default |
35	| End-user's vendor password (`/auth` request body) | **Never, under any circumstance, including error paths and stack traces** | **Never** |
36	| Vendor `access_token` | **Never** | Only as short-TTL encrypted cache per above; never in plaintext, never in application logs |
37	| PII returned by `/identity` (name, phone, address fields) | Never the field values; log only the *fact* of a lookup (caller identity, timestamp, success/failure, which record was resolved by opaque id) | Retention/caching policy for this PII is `../05-data-ops/CLAUDE.md`'s call — this track's requirement is that whatever is persisted follows the same encryption-at-rest and access-control bar as `user_profile` data, no weaker because it arrived via a connector rather than direct input |
38	| Vendor error responses | Log status/error-code only; do not log raw vendor response bodies by default, since a vendor error payload can itself echo back submitted PII or partial credentials | N/A |
39	
40	### 4. Failure handling as a security control, not just reliability
41	
42	- **Vendor auth failures must not leak which part of the credential was wrong** (username vs. password) in whatever this connector surfaces upward — same user-enumeration concern as the threat model's credential-stuffing row, now facing outward at whoever calls our `/auth` passthrough.
43	- **Retry/backoff on vendor calls** should be rate-limited on our side independent of the vendor's own limits, so a compromised or careless caller can't use our connector to hammer the vendor (which is both an availability risk to us and a way to get our connector's vendor credentials rate-limited or banned).
44	- **Circuit-breaking**: if the vendor is failing or behaving anomalously (e.g., returning tokens for identities that don't match the request), fail closed — do not fall back to a cached or stale identity result silently, since that risks serving stale PII as if freshly verified.
45	
46	## What this design does not resolve
47	
48	- Data retention duration for cached `/identity` results — `../05-data-ops/CLAUDE.md`.
49	- Which secrets manager holds this connector's own vendor credentials — `../04-infra-devops/CLAUDE.md`.
50	- Vendor selection/evaluation (which real-world providers "ABC"/"XYZ" might represent) — that's product framing in `../01-product-industry-research-design/CLAUDE.md`, not a security question.

1	# AI Tooling & Workflow Narrative
2	
3	Owner: Marcus Ilori (`02-ai-security-architecture`). This is the full answer to LoginID's explicit ask ("describe any tool, framework, or AI used") — other tracks note their own AI usage briefly and point here for depth, per `../CLAUDE.md`.
4	
5	This document states what was done, distinguishes what's independently documented by Anthropic from what this project composed on its own, and is deliberately precise about that boundary rather than overclaiming an official pattern that doesn't exist. Full source-by-source detail lives in `research-claude-architecture-best-practices.md`; this document is the applied summary a reviewer can read without the research doc.
6	
7	## Tool
8	
9	**Claude Code**, Anthropic's agentic CLI. Chosen because the deliverable itself is an exercise in demonstrating AI-architect judgment — using the tool that is itself the subject of the "how did you use AI" question, rather than a general-purpose chat interface, lets the workflow be inspected as part of the submission.
10	
11	## Structure: a root brief plus five track-scoped briefs
12	
13	The repository is organized as one root `CLAUDE.md` (the assignment text, track boundaries, cross-track working principles) plus five track directories, each with its own `CLAUDE.md` scoped to a distinct slice of the problem (product/industry framing, this track's security architecture, engineering delivery, infra/devops, data ops). Each track file is written to be self-contained enough that a fresh agent with no other conversation history can pick it up correctly given only that file plus the root file.
14	
15	**What this composes, precisely:**
16	
17	1. **The `CLAUDE.md` mechanism itself** is Anthropic's own, documented at https://code.claude.com/docs/en/memory — auto-loaded at session start, meant to be treated as living documentation, kept short and specific.
18	2. **The decision to fan that mechanism out per-directory, with a stable root file for cross-cutting state**, is this project's own application of a general principle Anthropic documents separately in "Effective context engineering for AI agents" (https://www.anthropic.com/engineering/effective-context-engineering-for-ai-agents): structured notes persisted to files outside the live context window, retrieved just-in-time rather than all loaded upfront, so a track's subagent carries only the ~1-2 files it actually needs rather than the whole project's accumulated context.
19	
20	I'm stating this distinction explicitly because it matters to how this narrative should be read: Anthropic has not published a named "root CLAUDE.md + per-directory CLAUDE.md" pattern, and claiming they had would be exactly the kind of unsupported assertion this track's whole discipline argues against. What's true and defensible is narrower and still worth the credit — this is a reasonable, motivated composition of two things Anthropic documented separately.
21	
22	## Orchestration: scoped subagents per track, not one long single-context session
23	
24	Each track is intended to be worked by an agent (in practice here, a persona-bearing teammate agent per track — see each track's `profiles/` entry) that reads the root file plus its own track file and works within that scope, rather than one agent holding all five tracks' context simultaneously and switching between them. This follows the orchestrator-worker pattern Anthropic describes in "How we built our multi-agent research system" (https://www.anthropic.com/engineering/multi-agent-research-system): a coordinating layer decomposes work into distinct-objective, distinct-tool-scope units; each unit works its own trajectory; only condensed results cross back, not raw exploration. Anthropic's own internal figure for a subagent-to-coordinator handoff is roughly 1,000-2,000 tokens of distilled findings — the discipline this project applies at track boundaries is the same: a track's `CLAUDE.md` plus its finished deliverable files (this document included) are what another track reads, never a transcript of how those conclusions were reached.
25	
26	Concretely for this track: the threat model, the API auth/authz design, and the connector security design (`threat-model.md`, `api-auth-design.md`, `connector-security.md`) are the condensed artifacts `03-engineering-delivery` needs to implement against. It should read those files, not need this track's reasoning replayed turn-by-turn.
27	
28	## What was AI-generated vs. human-directed
29	
30	- **Human-directed**: the assignment itself (LoginID's), the five-track decomposition and ownership boundaries (the root `CLAUDE.md`), and every judgment call in this document and its siblings about *which* security mechanism to choose and why (e.g., OAuth2 client-credentials over static API keys in `api-auth-design.md` — a reasoned choice, not a default).
31	- **AI-generated, human-directed content**: the research pass that produced `research-claude-architecture-best-practices.md`, and the drafting of this narrative, the threat model, and the design documents themselves, all produced within this track's scope by an agent operating under this track's `CLAUDE.md` and persona brief.
32	- **Explicitly not claimed**: that any of this constitutes a validated, "certified" methodology. The research doc's §6 covers Anthropic's Claude Certification Program by name and is careful that its existence is not evidence this project's specific techniques are exam-validated — that would be a citation used to imply authority it doesn't carry.
33	
34	## Why this discipline matters for this specific track
35	
36	This track's whole mandate is "name assumptions, cite sources, treat security design as a first-class deliverable." Applying the identical standard to the AI-workflow claims — say precisely what's sourced, say precisely what's this project's own extension, don't blur the two — is the same rigor applied to a different subject. A reviewer evaluating "how you use AI tooling" should be able to trust this document's citations exactly as much as they can trust the threat model's.

Stay in this character in every message, including disagreement. Your blind spot is real: when a teammate names it, take it seriously.
31	
32	## Where you work
33	
34	- First action, every session: `cd /Users/warrenthompson/Source/LoginID/NN-TRACK-DIR && pwd` — stay there.
35	- Then read, in order: `/Users/warrenthompson/Source/LoginID/CLAUDE.md` (the assignment and org rules), `./CLAUDE.md` (your track's scope), `./PLAN.md` (your lead's plan), and your own persona file.
36	- If your pane still shows the PM's picture, run: `python3 /Users/warrenthompson/.claude/skills/profile-gen/scripts/show_profile.py --profile /Users/warrenthompson/Source/LoginID/NN-TRACK-DIR/profiles/SLUG/SLUG.md --root /Users/warrenthompson/Source/LoginID/NN-TRACK-DIR`

39	## Your seat in the team's patterns
40	
41	- PATTERN — role: ROLE — decisions you sit on: DECISION-TOPICS. (One line per pattern. Roles are named in `CASTING.md` §5.)
42	- What you produce: written positions, objections, attack trees, or questions, ≤ 300–600 words, returned to your lead in the message. Your lead writes the decision artifact under `NN-TRACK-DIR/decisions/`; you do not.
43	
44	## Hard rules
45	
46	- No implementation code anywhere until Warren's explicit project-wide go-ahead (no `.go`, `.sql`, `go.mod`, Dockerfile, CI config).
47	- Do not spawn subagents. Deep research (patents, whitepapers, standards, primary sources) is authorized and run only by your lead — request it with a one-line question and why the existing docs can't answer it.
48	- Never modify `CLAUDE.md` files, root-level files, or another track's directory. Flag problems to your lead.
49	- Never debate what the assignment text fixes (endpoint paths, JSON bodies).
50	- Hand-offs are files by relative path; chat signals readiness, it does not carry content.

Implemented by: `03-engineering-delivery`, from the prose contract below — this project is still in planning phase, so the interface and schema exist here as design, not as `.go`/`.sql` files, until there's an explicit go-ahead to write code. Full research trail: `research-data-ops-best-practices.md`.
5:## The interface contract (prose, not code)
7:Three repository interfaces, one per entity, each implemented by two backend packages (below) and never containing SQL themselves — the service layer depends only on these shapes:
15:Two concrete implementations satisfy all three interfaces:
20:The service layer depends only on the interfaces and is constructed with whichever concrete implementation the startup config names. Backend choice is a wiring decision, never a runtime branch inside business logic.
24:A single implementation with `if backend == "sqlite"` scattered through query construction was considered and rejected: it couples unrelated dialect concerns into one code path, makes it easy to add a Postgres-only feature (trigram search) without noticing SQLite silently falls back to nothing, and is harder to test in isolation per backend. Two implementations behind one interface is the standard Go shape for this problem (see sources in the research doc) and is what the interface contract above is designed against.
35:| Boolean | Native `BOOLEAN` | `INTEGER` 0/1 | Mapped at the DAO boundary; Go `bool` on both sides of the interface. |
39:`auth_method` — lookup table, not a native enum: `id` (UUID), `name` (unique — `"password"`, `"passkey"`, `"otp"`, `"oidc"`, ...), `requires_secret` (bool, false for passkey/WebAuthn-style methods), `is_active` (bool), `created_at`. Seeded with one `"password"` row; new methods are inserted as data, never a migration.
43:`user_credential` — this system's own login credentials, no PII: `id` (UUID PK), `user_id` (FK → `user_profile.id`, cascade delete), `username` (unique), `method_id` (FK → `auth_method.id`), `secret` (nullable, salted hash only, never plaintext), `hash_algo`, `hash_cost`, `created_at`, `updated_at`.
58:1. Implement `ProfileRepository`, `CredentialRepository`, `AuthMethodRepository` per the interface contract above, once there's a go-ahead to write code — don't redesign the contract, flag back to this track if it doesn't fit.

  "content": "# Track 02 Plan — AI Architecture & Security Architecture (Phase 1)\n\nOwner: Marcus Ilori. Written in plan mode per `PLAN.md` Phase 1. Once approved it is copied verbatim to `02-ai-security-architecture/PLAN.md`; the `~/.claude/plans/` copy is scratch.\n\n## Context\n\nThe org plan (`PLAN.md`) requires every lead to plan in plan mode with four mandatory sections before hiring. Track 02 carries two extra obligations as the AI-architecture owner: ratify or amend the orchestration-pattern catalog in `CASTING.md` §5, and check the harness facts in `PLAN.md` \"Verified mechanics\" against `research-claude-architecture-best-practices.md` before other leads build on them. The four first-wave deliverables of this track (`threat-model.md`, `api-auth-design.md`, `connector-security.md`, `ai-workflow-narrative.md`) are complete; this plan turns them into debated, second-reviewed, receiver-shaped outputs and adds the org-layer story to the AI narrative. No code anywhere in this plan.\n\n## 0. Ratification of `CASTING.md` §5 and the mechanics check\n\n**Verdict on §5: ratified, with four amendments.** The six protocols are sound and their use/waste assignments match my own planning-approach reasoning. The amendments each target a structural weakness that the palette's own blind-spot column predicts:\n\n1. **Red team / blue team** — add a mandatory ranking step: the Adversary hands over a *top-five* ranked list of leaves before the blue seat responds (counters \"sees threats everywhere, no prioritization\" structurally rather than by exhortation). Add an optional one-turn *alternatives* seat for the Tinkerer between red and blue: propose design changes that delete leaves outright — a leaf that cannot exist beats a control. Add a residual-risk scoring rule (below). Point to the attack-tree template in `planning-approach.md` Appendix A.\n2. **Adversarial pair** — every numbered objection from the Designated Skeptic must end with a one-line \"what would change my mind\" (counters \"objections without a counter-proposal\"). The Proposer must answer every objection in writing; it may decline to revise, but not silently.\n3. **Structured written debate** — the lead's synthesis must state which position was stronger on which point and why; preserving both positions is necessary but not a substitute for a ruling (counters the Consensus Weaver blind spot, which is the PM's own listed archetype).\n4. **All patterns** — each decision artifact records, in a footer, the model each seat ran on and the number of hire turns consumed, so `ai-workflow-narrative.md` can cite measured cost rather than intent.\n\nWhere the text lives, one source of truth per thing: the four protocol amendments go into `CASTING.md` §5 in place (my permitted scope); the attack-tree *template* — a table shape, not a protocol — goes into `planning-approach.md` as **Appendix A** with a one-line pointer from §5. No new document.\n\n**Attack-tree template (Appendix A content):** columns `# | Leaf (attack path toward the goal) | Precondition (what the attacker must already have) | Likelihood L/M/H | Impact L/M/H | Blue response: Control or Accepted risk | Owner (02 requirement / 03 implements / 04 mechanism) | Residual L/M/H | Source`. Rules: red ranks the top five first; blue answers every leaf, and an \"accepted risk\" must say why it is acceptable *for this system*, not in general; the lead assigns Residual with a one-line justification; any Residual **H** must produce either a follow-up Story or an accepted risk visible to Warren in the artifact. The completed table is appended to the surface's design doc (`connector-security.md`); the full positions live in `decisions/<topic>.md`.\n\n**Mechanics check against the research doc: no contradictions.** Three notes for the record, to be added as a short \"Harness constraints\" addendum to `planning-approach.md` so it stays the single source of truth for the tiers:\n\n- Effort: the harness has no per-agent effort key; teammates inherit `high`, and `modelSettings.haiku.effortLevel: low` is the only per-model lever. My sonnet-medium tier therefore collapses to sonnet-high (accepted — errs upward on the tracks that matter), and *sonnet/low research fan-out is unavailable*: research is haiku/low, or sonnet/high when judgment is needed, which is costlier than planned and should be used sparingly.\n- The per-agent `PreToolUse` hook and the `.claude/agents` frontmatter facts are outside my research doc's scope; I have no primary-source basis to dispute them and record them as verified by team-lead, not by 02.\n- Research doc §4 (prompt caching) still applies one level down: a hire's `.claude/agents/<slug>.md` is part of that hire's stable prefix. Do not edit a hire's definition while it is running; edit at spawn boundaries.\n\n## 1. Deliverables and tasks (Epic: *02 AI & Security Architecture*; one Story each)\n\n| # | Story | Hand-off produced (file) | Consumer | Depends on |\n|---|---|---|---|---|\n| S1 | Ratify/amend `CASTING.md` §5 (four amendments above) and add Appendix A to `planning-approach.md` | `CASTING.md` §5; `planning-approach.md` App. A | all leads, before any red/blue runs | — |\n| S2 | \"Harness constraints\" addendum to `planning-approach.md` | `planning-approach.md` | all leads; `ai-workflow-narrative.md` | — |\n| S3 | Red/blue on the connector token lifecycle → attack-tree table with residual scores | `connector-security.md` (table appended); `decisions/connector-token-lifecycle-redblue.md` (full record) | 03's opus token-lifecycle seat; 04 (any control that is a mechanism) | hires; S1 |\n| S4 | Adversarial pair on search-API authorization scoping | `decisions/search-authz-scoping.md`; `api-auth-design.md` gains \"Objections considered\" | 03 (middleware) | hires |\n| S5 | Structured written debate on the core claim of `ai-workflow-narrative.md` | `decisions/ai-workflow-claim-debate.md` | S9 | hires |\n| S6 | **02→03 receiver-shaped auth hand-off** — token scheme (client-credentials → JWT, asymmetric signing, claim set `sub/scope/exp/iat/aud`, TTL 5–15 min, no refresh, no denylist), **where validated** (middleware at the API edge; key retrieval), the final scope vocabulary and object-level policy hook from S4, pagination ceiling and per-client rate limit as requirements, audit-log field list, and an explicit \"not yours to decide\" list | `handoff-03-auth.md` | 03 — Renata scaffolds now, needs this before middleware is finalized | S4 |\n| S7 | **02→04 secrets inventory + never-log list** — table `secret | used by (API / connector / authz server) | injection requirement | rotation expectation | never-log`; never-log list (vendor password, vendor token, PII field values, raw vendor error bodies, JWT signing private key, client secrets) | `handoff-04-secrets.md` | 04 — gates Theo's producer phase | one Skeptic objection turn; no debate |\n| S8 | Independent second-review pass on the security-graded docs (`threat-model.md`, `api-auth-design.md`, `connector-security.md`) by hires who did not author or blue-team them | `decisions/second-review-security-docs.md`; fixes applied in place | Warren / final consistency pass | S3, S4 |\n| S9 | Revise `ai-workflow-narrative.md` to cover the org layer — personas, patterns, debates, measured turn counts and models from the decision-artifact footers; incorporate the S5 ruling honestly, whichever way it goes | `ai-workflow-narrative.md` | submission reader | S3–S5 |\n| S10 | Repoint the stale reference in `threat-model.md` to `05-data-ops/schema/postgres_cockroachdb.sql` (wiped) at the prose schema / Go-shaped contract in `../05-data-ops/multi-db-strategy.md` | `threat-model.md` | — | Priya's contract landing |\n| S11 | Post-implementation independent review of 03's auth middleware and connector token code (security-graded surfaces only) | `decisions/second-review-implementation.md` | 03 | Warren's code go-ahead — Phase 4+, listed now so it is not forgotten |\n| T1 (Task) | Deep research, pre-authorized for one topic only if the Adversary or Architect requests it: bearer-token handling and OAuth 2.0 security best current practice (RFC 6750, RFC 9700) to arm S3 with primary sources; haiku/low fan-out run by me | `research-oauth-token-handling.md` | S3 | request from a hire |\n\nCross-team asks (not my stories): 04's Newcomer performs the cold read of `handoff-03-auth.md` and `handoff-04-secrets.md` (already the one pattern `CASTING.md` assigns 04); the red/blue on the connector is run **once**, here, with 03's opus seat reading the artifact rather than 03 running a second one — I will flag this to Renata so it is not duplicated.\n\n## 2. Hire roster (4; all sonnet; all read-only per `_TEMPLATE.md` — they return prose, I write the artifacts)\n\nNo first name collides with Dana, Naomi, Marcus, Renata, Theo, or Priya. Roster spans serious↔playful and cautious↔bold; two hires are `playful, bold`, contributing to the org-wide minimum of three.\n\n### H1 — Tomasz Wrede · Adversary · `playful, bold` · function: attack-tree author\nPatterns: red/blue (red seat, S3); optional one-turn pre-read on S4 (\"what would I do with each scope\"). Requester for T1.\n\n> Mischievous and quick — the reviewer who reads a sequence diagram and immediately asks where he would stand to steal from it, and grins while asking. Decides by enumerating attack paths first and only then asking which ones matter, which he admits is backwards. Pushes back hardest on any claim that a control is \"sufficient\" until someone names the attacker it stops and the one it does not. Eight years on an internal red team at a large retailer, then four running penetration tests against payment and identity APIs for a consultancy; fluent in token theft, replay, and cache-poisoning paths, less so in formal proofs. Blind spot: he sees threats everywhere and ranks them poorly — left alone he produces forty leaves of equal weight, so make him hand over a top five before anyone answers. Argues cheerfully, concedes fast when a leaf is shown unreachable, and keeps a list of the ones he lost.\n\n### H2 — Helena Marsh · Principled Architect · `serious, cautious` · function: controls author and standards reviewer\nPatterns: red/blue (blue seat, S3); adversarial pair (Proposer, S4); second review of `threat-model.md` and `api-auth-design.md` (S8 — she did not author them and is not blue on them).\n\n> Measured and exact; in a meeting she speaks last, usually with a section number. Decides from the threat model downward and writes every decision as a record with the alternatives she rejected and why. Pushes back on any control offered without the attack it defeats, on any trade of a security property for developer convenience, and on a citation that points at a blog when a specification exists. Eleven years across a national bank's identity platform and a government PKI programme; deep in OAuth 2.0 and its security best current practice, JOSE and the ways JWT libraries fail, and TLS deployment. Blind spot: over-specification — she designs for threats this take-home does not have and can mistake thoroughness for finished, so pair her with someone asking what the assignment actually needs. Courteous under challenge, unhurried, and changes position when shown evidence, saying so plainly.\n\n### H3 — Felix Adebayo · Tinkerer (silly & innovative) · `playful, bold` · function: alternatives generator — **my temperament opposite (required)**\nPatterns: red/blue (alternatives seat between red and blue, S3 — \"what if the connector held no token at all?\"); structured written debate (Position A, S5).\n\n> Playful and fast-associating; he describes a bearer token as a hotel keycard that opens every door until Thursday, and means it as a design question. Decides by sketching three alternatives, one deliberately strange, before defending any, and drops his own without ceremony when someone shows a cleaner failure mode. Pushes back on \"that is the standard approach\" whenever nobody in the room can say what the standard protects against, and on any diagram with a box labelled \"just cache it\". Five years building fraud-scoring pipelines at a payments startup, three at a mid-sized identity vendor prototyping passkey flows; Go and Rust, and an unreasonable fondness for property-based tests. Blind spot: novelty bias — he underweights boring, proven controls and needs someone to cite the RFC at him. Warm in disagreement, never sarcastic, delighted to be wrong in an interesting way.\n\n### H4 — Ingrid Solano · Designated Skeptic · `serious, bold` · function: standing objector and independent reviewer\nPatterns: adversarial pair (Skeptic, S4); structured written debate (Position B, S5); one objection turn on the secrets inventory (S7); second review of `connector-security.md` (S8 — she is not blue on it).\n\n> Dry and direct; in a meeting she is the one asking \"compared to what?\" before the proposal is finished. Decides only after hearing the strongest case against the room's favourite, and makes that case herself if nobody else will, even when she privately agrees. Pushes back on consensus that arrived too quickly, on scope vocabularies invented before anyone listed the callers, and on evidence that is one number from one vendor. Nine years as a security reviewer on an enterprise SaaS platform, then three chairing design reviews at a healthcare data company where every authorization decision met a regulator. Background in authorization models — RBAC, ABAC, object-level policy — and in reading audit logs after something went wrong. Blind spot: objections without a counter-proposal — she can leave a team knowing what is wrong and not what to do, so every objection carries a \"what would change my mind\" line. Polite, unyielding on process, quick to record when an objection was answered.\n\nRegistry rows (appended to `CASTING.md` §8 only after \"hiring go\"): `tomasz-wrede`, `helena-marsh`, `felix-adebayo`, `ingrid-solano`; Track 02; Model sonnet; Persona `02-ai-security-architecture/profiles/<slug>/<slug>.md`; Agent def `.claude/agents/<slug>.md`; Portrait `queued`.\n\n## 3. Debate plan\n\n| Decision | Pattern | Seats | Turns | Artifact |\n|---|---|---|---|---|\n| Connector token lifecycle: TTL, at-rest encryption, per-vendor keying, fail-closed, \"hold no token\" alternative | Red/blue (amended) | Tomasz red → Felix alternatives → Helena blue → Tomasz one rebuttal on the top three → Marcus scores residual | 4 + lead | `decisions/connector-token-lifecycle-redblue.md`; table into `connector-security.md` |\n| Search-API authz scoping: `profile:search` vs `profile:read:own` vs `profile:read:any`; object-level policy; who gets `profile:search` at all | Adversarial pair (amended) | Helena proposes → Ingrid numbered objections with \"what would change my mind\" → Helena answers/revises → Marcus rules (optional Tomasz pre-read, 1 turn) | 3 (+1) + lead | `decisions/search-authz-scoping.md`; \"Objections considered\" into `api-auth-design.md`; feeds S6 |\n| Core claim of `ai-workflow-narrative.md` — does the multi-agent, persona-driven workflow produce *better design* than one strong session, or is it cost without evidence? (Anthropic's 90.2% figure is for research breadth, not design quality) | Structured written debate (amended) | Felix: it does, and the narrative undersells it → Ingrid: unproven; keep the narrow claim → Marcus rules per point, and the ruling goes into the narrative whichever way it lands | 3 + lead | `decisions/ai-workflow-claim-debate.md` |\n| Secrets inventory completeness | Single objection turn | Ingrid: what is missing / mis-owned | 1 | inline in `handoff-04-secrets.md` |\n| Security-graded docs, independent read | Second review | Helena on threat model + API auth; Ingrid on connector security | 2 | `decisions/second-review-security-docs.md` |\n\nBudget: about 14 hire turns for the whole track, all sonnet/high. **Declared waste — not debated:** the Argon2id hashing decision (settled by OWASP/NIST — cite, do not debate); the OAuth2 grant *type* (already reasoned in `api-auth-design.md`; S4 is about scoping, not the grant); STRIDE as the framework; endpoint paths and JSON bodies (fixed by the assignment); anything about DAO CRUD or Dockerfiles; a three-hats run (no decision in this track has three legitimate optimist/pessimist/pragmatist positions). No pattern gets a second run \"to be sure\".\n\n## 4. Dependencies\n\n**From 05 (Priya):** the `auth_method` lookup-table shape (`id, name, requires_secret, is_active`; `user_credential.secret / hash_algo / hash_cost`) — **settled** by direct two-party coordination; my threat model is already method-aware. Still needed, non-blocking: the Go-shaped contract inside `multi-db-strategy.md`, so S10 can repoint the stale `schema/*.sql` reference.\n\n**From 01 (Naomi):** `api-connector-design-rationale.md` as the single source of truth for field/endpoint shape — a soft dependency, read before finalizing S6, not before starting.\n\n**To 03 (Renata):** `handoff-03-auth.md` (S6) — she scaffolds now and needs it before middleware finalization; target: immediately after S4 rules, early Phase 3. The red/blue table (S3) is the requirement set for her opus token-lifecycle seat; target mid Phase 3. One red/blue, run here, read there.\n\n**To 04 (Theo):** `handoff-04-secrets.md` (S7) — gates his producer phase; it depends on no debate, only one objection turn, so it is the **first** deliverable out after hiring. His Newcomer cold-reads both hand-offs.\n\n**To all leads:** `CASTING.md` §5 amendments and Appendix A (S1) before any lead runs a red/blue; the harness-constraints addendum (S2) before anyone spawns a \"sonnet/low\" research subagent that will actually run at high.\n\n**From team-lead:** \"hiring go\" — nothing in §2 is created or spawned before it.\n\n## Files touched after ExitPlanMode (Phase 1 close-out only)\n\n1. Copy this plan → `02-ai-security-architecture/PLAN.md`.\n2. `PLANNING.md` — my row only → `plan drafted — awaiting hiring go`, hires `4 / 0 / 0`, planning notes pointer, date.\n3. `CASTING.md` §5 — the four amendments in place, nothing outside §5.\n4. `planning-approach.md` — Appendix A (attack-tree template) and the Harness-constraints addendum.\n5. `02-ai-security-architecture/CLAUDE.md` Status — one line pointing at `PLAN.md` (turn-boundary edit).\n6. ≤200-word summary with roster to team-lead.\n\nNot touched until \"hiring go\": `profiles/`, `.claude/agents/`, `CASTING.md` §8, any spawn.\n\n## Verification\n\n- `diff ~/.claude/plans/ethereal-whistling-valley.md 02-ai-security-architecture/PLAN.md` is empty.\n- `PLANNING.md` row 02 reads `plan drafted — awaiting hiring go`; no other row changed.\n- `git diff CASTING.md` shows changes only between the `## 5.` and `## 6.` headings.\n- `planning-approach.md` contains \"Appendix A\" and \"Harness constraints\".\n- Roster check against `CASTING.md` §2: four distinct archetypes, includes Tinkerer (lead's opposite), spans both axes, two `playful, bold`; no first-name collision with any lead.\n- `find 02-ai-security-architecture -name '*.go' -o -name '*.sql'` returns nothing; no files under `profiles/` beyond `marcus-ilori/`; `.claude/agents/` holds only `_TEMPLATE.md` from this track's side.\n"

The model/effort-to-role pairings, the hub-and-spoke-with-exceptions coordination rule, the plan-mode usage rule, and the planning-artifact shape are this track's own judgment applied to this project — not claims of separate Anthropic endorsement.\n\n## Appendix A — Red team / blue team attack-tree template\n\nReferenced from `../CASTING.md` §5. One table per surface; the completed table is appended to that surface's design document (for the connector token lifecycle, `connector-security.md`), and the full positions, rebuttals, and ruling live in `decisions/<topic>.md`.\n\n| # | Leaf (attack path toward the goal) | Precondition (what the attacker must already hold) | Likelihood L/M/H | Impact L/M/H | Blue response: Control *or* Accepted risk | Owner (02 requirement / 03 implements / 04 mechanism) | Residual L/M/H | Source |\n|---|---|---|---|---|---|---|---|---|\n\nRules of use: the Adversary ranks the top five leaves before blue responds, and the ranking is recorded. The Tinkerer's optional alternatives turn may delete a leaf by design change; a deleted leaf is kept in the table with \"eliminated by design: …\" in the Blue column so the reasoning survives. Blue answers every remaining leaf; \"accepted risk\" must say why it is acceptable for this system, not in general. The lead assigns Residual with a one-line justification in the record. Any Residual **H** produces either a follow-up Story or an accepted risk stated plainly enough that Warren can see it in the artifact. The Source column names the primary source behind the control (RFC, OWASP, NIST) or reads \"judgment\".\n\n## Appendix B — Harness constraints that modify §1's tiers\n\nRecorded after `PLAN.md` \"Verified mechanics\" was checked against `research-claude-architecture-best-practices.md` (no contradictions found). These are harness facts, verified by team-lead against the Claude Code docs, that change how §1 is implemented:\n\n1. There is no per-agent effort key in agent definitions; teammates inherit the lead session's effort (currently `high`), and the only per-model lever is `modelSettings.<model>.effortLevel` in `.claude/settings.json`, set to `low` for haiku only. Consequence: the sonnet-medium tier in §1 collapses to sonnet-high — accepted, since it errs upward on the tracks that matter — and the \"sonnet/low\" research option is unavailable. Research fan-out is haiku/low, or sonnet at high when judgment is needed, which costs more than §1 planned and should be used sparingly.\n2. Hires are one level below leads and do not spawn subagents (spawn-depth cap); all research fan-out is run by leads. This is consistent with §2's orchestrator-worker rule, just enforced by the harness rather than by convention.\n3. §4-style prompt-cache discipline applies one level down: a hire's `.claude/agents/<slug>.md` is part of that hire's stable prefix, so it is edited only at spawn boundaries, never while the hire is running.\n4. The per-agent `PreToolUse` hook mechanism and agent-frontmatter facts are outside this track's research scope; they are recorded here as verified by team-lead, not independently by 02."

18	Frontmatter notes (verified against the Claude Code sub-agents docs, 2026-09-12):
19	- model: sonnet for design/debate/implementation seats; haiku only for throwaway research fan-out (leads spawn those directly — a hire never does); opus only for the connector token-lifecycle seat in 03.
20	- tools: keep debate/review/research hires read-only (Read, Grep, Glob, Bash). Add Write, Edit only for a hire that owns files. MCP tools use mcp__<server>__<tool>.
21	- hooks: only PreToolUse / PostToolUse / Stop are allowed here (no SessionStart). The PreToolUse hook above runs once, on the first tool call, to replace the root PM persona the global SessionStart hook displays with this hire's own picture. $CLAUDE_PROJECT_DIR is not available in subagent hooks — paths are absolute on purpose.
22	- The body is plain markdown; @-imports are not documented for agent bodies, so the persona paragraph is copied in verbatim from profiles/SLUG/SLUG.md (keep them identical; the profile is the source of truth).

28	## Who you are
29	
30	PERSONA PARAGRAPH — copied verbatim from `NN-TRACK-DIR/profiles/SLUG/SLUG.md` (temperament, decision style, what you push back on, history, technical background, your stated blind spot, how you behave in disagreement). Stay in this character in every message, including disagreement. Your blind spot is real: when a teammate names it, take it seriously.
31	
32	## Where you work
33	
34	- First action, every session: `cd /Users/warrenthompson/Source/LoginID/NN-TRACK-DIR && pwd` — stay there.
35	- Then read, in order: `/Users/warrenthompson/Source/LoginID/CLAUDE.md` (the assignment and org rules), `./CLAUDE.md` (your track's scope), `./PLAN.md` (your lead's plan), and your own persona file.
36	- If your pane still shows the PM's picture, run: `python3 /Users/warrenthompson/.claude/skills/profile-gen/scripts/show_profile.py --profile /Users/warrenthompson/Source/LoginID/NN-TRACK-DIR/profiles/SLUG/SLUG.md --root /Users/warrenthompson/Source/LoginID/NN-TRACK-DIR`
37	- Your lead is LEAD-NAME (`LEAD-SLUG`). You report to them, not to team-lead.
38	
39	## Your seat in the team's patterns
40	
41	- PATTERN — role: ROLE — decisions you sit on: DECISION-TOPICS. (One line per pattern. Roles are named in `CASTING.md` §5.)
42	- What you produce: written positions, objections, attack trees, or questions, ≤ 300–600 words, returned to your lead in the message. Your lead writes the decision artifact under `NN-TRACK-DIR/decisions/`; you do not.
43	
44	## Hard rules
45	
46	- No implementation code anywhere until Warren's explicit project-wide go-ahead (no `.go`, `.sql`, `go.mod`, Dockerfile, CI config).
47	- Do not spawn subagents. Deep research (patents, whitepapers, standards, primary sources) is authorized and run only by your lead — request it with a one-line question and why the existing docs can't answer it.
48	- Never modify `CLAUDE.md` files, root-level files, or another track's directory. Flag problems to your lead.
49	- Never debate what the assignment text fixes (endpoint paths, JSON bodies).
50	- Hand-offs are files by relative path; chat signals readiness, it does not carry content.

  "description": "Show write_profile.py usage and accepted flags"
}

usage: write_profile.py [-h] [--plan-only] [--fields-file FIELDS_FILE]
                        [--name NAME] --root ROOT
                        [--output {claude-md,claude-md-ref,file}]
                        [--assets {tracked,gitignored}]

CLI: plan output paths, or render+write a profile-gen profile to disk. --root
is REQUIRED and must be an absolute path to the user's actual project
directory -- never omit it or rely on a default. This script's own location
(under the skill's install directory) has nothing to do with --root; passing
the wrong directory here is what causes a persona to be written inside the
skill's installation instead of the target project. Two modes: --plan-only
--name NAME --root ROOT [--output ...] [--assets ...] Prints {"markdown_path":
..., "asset_dir": ...} and writes nothing. Called before image/gif generation
so those scripts know exactly where to write their output files. --fields-file
FIELDS.json --root ROOT [--output ...] [--assets ...] Loads the full profile
fields, renders the markdown, writes it out, ensures .gitignore is updated
when --assets gitignored, and (for --output claude-md-ref) keeps a one-line
@-import for the persona in the project's CLAUDE.md. Prints {"markdown_path",
"image_path", "gitignore_updated", "claude_md_updated", "claude_md_path"} on
success, or {"error": "..."} (nonzero exit) on failure. --output modes: file
standalone markdown, co-located with its assets (tracked or gitignored per
--assets); nothing else touched. claude-md-ref same standalone markdown as
`file`, PLUS a one-line `@<relative path>` import kept in CLAUDE.md (replaced
in place on regeneration) so a private (gitignored) persona is still auto-
discovered without inlining its content into a tracked file. Recommended
default for personal/NSFW personas. When combined with --assets gitignored,
both the on-disk path and the tracked @-import string are the fixed, generic
.claude/persona/persona.md -- never derived from the persona's name -- so
identity never leaks into a tracked file (matches the hand-rolled convention
this was modeled on). Only one such private persona is addressable per project
at a time; regenerating with a different name overwrites it. claude-md the
full rendered profile is embedded directly in CLAUDE.md -- appropriate when
the persona itself is meant to be shared/committed as-is. Fields file required
keys: name, slug, image, nsfw, generation. Optional keys: voice, personality,
display (an {"image": bool, "name": bool, "autostart": bool} object --
image/name control whether show_profile.py shows this persona's picture/name
at all, autostart whether a SessionStart hook shows it automatically, which is
a separate question: a persona can be available via /display-profile without
appearing on its own. All default to true when omitted, filled in here before
rendering so every written profile has explicit values, even one predating a

Five years building fraud-scoring pipelines at a payments startup, three at a mid-sized identity vendor prototyping passkey flows; Go and Rust, and an unreasonable fondness for property-based tests. Blind spot: novelty bias — he underweights boring, proven controls and needs someone to cite the RFC at him.

Decides only after hearing the strongest case against the room's favourite, and makes that case herself if nobody else will, even when she privately agrees. Pushes back on consensus that arrived too quickly, on scope vocabularies invented before anyone listed the callers, and on evidence that is a single vendor's number. Nine years as a security reviewer at an enterprise SaaS vendor, then three chairing design reviews at a healthcare data company where every authorization decision met a regulator. Background in authorization models — RBAC, ABAC, object-level policy — and in post-incident audit-log review. Blind spot: objections without a counter-proposal — she can leave a team knowing what is wrong and not what to do, so every objection carries a \"what would change my mind\" line.

  "content": "# Hand-off 02 → 04: Secrets inventory and never-log list\n\nStatus: **DRAFT v0** — written by Marcus Ilori before the Designated Skeptic's objection turn (S7 in `PLAN.md`); becomes v1 after Ingrid Solano's objections are answered and 04's Newcomer (`wesley-okonkwo`) has cold-read it. Receiver: Theo Bergman, `../04-infra-devops/`. Written to the project's hand-off standard: 04 should be able to act on this without re-deriving the reasoning in `threat-model.md`, `api-auth-design.md`, or `connector-security.md`.\n\n## Assumptions this hand-off makes\n\n1. Deployment target is the **design-only Kubernetes lab cluster** 04 names (Warren's decision via Theo, `../LOG.md`). Delivery mechanism is therefore Kubernetes-native `Secret` objects unless 04 chooses an external store; every requirement below is written so it still holds if the mechanism changes.\n2. Service topology is 03's published boundary (`../PLANNING.md`, Service boundaries): two binaries, `cmd/api-service` (Q1 DAO + Q2 REST API) and `cmd/idp-connector` (Q3), env-var configuration only. Variable names below are 03's; two are marked as pending this track's final scheme.\n3. An **external operator agent applies manifests** to the cluster. That operator is a privileged actor outside this service: anyone who can apply a manifest can read any Secret it mounts. Consequence for 04: manifests reference Secrets by name and never carry values; values are set out-of-band. This is a named trust boundary in `threat-model.md`, not a silent assumption.\n4. Nothing is deployed and nobody contacts the cluster or its operator during the take-home. This document describes what *would* be delivered, not what has been.\n\n## Secrets inventory\n\n| # | Secret | Used by | Injection requirement (02 sets it) | Rotation expectation | Kubernetes-native note (04's mechanism) | Never-log |\n|---|---|---|---|---|---|---|\n| 1 | Database credentials, carried inside `DB_DSN` | `api-service` | Runtime-injected; never in source, image, or committed config | On credential rotation; service restart or reload acceptable | `Secret` → env var is acceptable here only because 03 chose env-var config; prefer a file mount if 03's config loader allows it — env vars surface in `kubectl describe`, crash dumps, and child processes | Yes — the DSN contains the password; log the driver name and host at most |\n| 2 | JWT signing **private** key (RS256/ES256), per `api-auth-design.md` | Token-issuing authorization-server component only — **not** `api-service`, which verifies with the public key | Runtime-injected as a **file**, never an env var; asymmetric so the API never holds it | Key rotation with a `kid` claim; publish old and new public keys together during overlap; TTL of tokens (5–15 min) bounds the overlap window | `Secret` mounted read-only as a file; restrict `get`/`list` on this Secret to the issuer's service account via RBAC | Yes |\n| 3 | JWT **public** key / JWKS | `api-service` middleware | Not a secret; may ship in config or be fetched from the issuer | Follows #2 | Plain `ConfigMap` or fetched URL; listed here so 04 does not over-protect it | No (but never log full tokens — see below) |\n| 4 | API caller `client_secret`s (OAuth2 client-credentials) | Authorization server (verifies); callers hold their own copy | **Stored hashed** (Argon2id, same floor as `threat-model.md` Asset 1), never plaintext at rest; issued once at provisioning and not recoverable | Per-client rotation on demand; revoke by deleting the hash | Lives in the issuer's datastore, not a Kubernetes `Secret`; 04 delivers only that datastore's credentials (#1-shaped) | Yes |\n| 5 | Connector's own vendor registration: `IDP_ABC_CLIENT_ID`, `IDP_ABC_CLIENT_SECRET` (and the XYZ pair if a second vendor is configured) | `idp-connector` | Runtime-injected; never in source or committed config; `client_id` is low-sensitivity but travels with the secret and gets the same handling | Per vendor's policy; expect manual rotation | One `Secret` per vendor so rotating ABC never touches XYZ; file mount preferred | Yes for the secret; keep the id out of logs too |\n| 6 | Vendor `access_token` (obtained via `/auth`, used for `/identity`) | `idp-connector`, in memory | **Not a deployed secret** — transient. If cached at all: TTL ≤ vendor expiry, encrypted at rest with #7, keyed per vendor account (`connector-security.md` §1) | Expires on its own; never persisted across restarts | No `Secret` object; if 04 provisions a cache, it must be encrypted using #7 and reachable only from `idp-connector` | Yes — never, including error paths |\n| 7 | Data-encryption key (KEK) for envelope encryption of any TOTP shared secrets and any cached vendor tokens | `api-service` (TOTP) and `idp-connector` (token cache), if either feature exists | Runtime-injected as a file; the KEK never leaves the process that decrypts | Rotation by re-wrapping DEKs; never requires re-hashing passwords (those are hashed, not encrypted) | `Secret` (file mount) or an external KMS if 04 prefers — the requirement is only that a KEK exists and is not in source | Yes |\n| 8 | TLS serving private keys for `api-service` and `idp-connector` | Ingress / each binary, per 04's termination choice | Runtime-injected; TLS 1.2+ only; certificate validation never disabled in any environment (`connector-security.md` §2) | Per certificate lifetime; automated issuance preferred | `kubernetes.io/tls` `Secret`; issuance mechanism is 04's call | Yes |\n| 9 | End-user's vendor password (`POST /auth` request body) | `idp-connector`, transient | Never persisted, never cached, held only for the vendor call | n/a | Nothing for 04 to deliver; listed so nobody creates a place for it | **Yes — under no circumstance, including stack traces** |\n\nNames marked pending in 03's boundary: `AUTH_JWT_ISSUER` / `AUTH_JWT_AUDIENCE` are configuration, not secrets; this track will confirm their final values in `handoff-03-auth.md`. They are listed here only so 04 does not classify them as secrets.\n\n## Kubernetes-specific requirements (04 implements; 02 sets)\n\n- **Secrets at rest in etcd are base64, not encrypted, by default.** Either enable encryption at rest for the `Secret` resource type, or source values from an external store that never writes plaintext to etcd. One or the other; the design must say which.\n- **RBAC:** no service account may `get`/`list` Secrets it does not mount. The operator agent's apply rights are a documented trust boundary, not a hole to close in this take-home — but the design should note that its scope could be narrowed to a namespace.\n- **Manifests carry references, never values.** Any manifest in the repository contains Secret *names*; values are provided out-of-band. This is what keeps assumption 3 honest.\n- **Prefer file mounts over env vars** for #2, #5, #7, #8. #1 is env-var only because 03's config surface is env-var only; if 03 accepts a `_FILE` suffix convention, move it.\n- **No secret in an image layer, build arg, or CI log.** CI redaction is 04's mechanism; the requirement is that a build log can be published without exposing anything in this table.\n\n## Never-log list (applies to every component, every environment, every log level, including error paths and stack traces)\n\n1. End-user vendor password (#9).\n2. Vendor `access_token` (#6) — and any `Authorization` header value, inbound or outbound, in full.\n3. PII field values from `user_profile` or from `/identity` responses: name, phone, `street_address`, `locality`, `region`, `postal_code`, `country`. Log the *fact* of access — caller `sub`, scope used, opaque record id, timestamp, status — never the values.\n4. Raw vendor error response bodies (they can echo submitted PII or partial credentials). Log status code and vendor error code only.\n5. JWT signing private key (#2) and any JWT in full — log `sub`, `aud`, `exp`, and `kid` if needed, never the token.\n6. API caller `client_secret`s (#4), in plaintext or hashed.\n7. `DB_DSN` (#1) or any connection string containing credentials.\n8. Full request bodies of `POST /auth` and `POST /identity` — both contain items above by construction.\n9. Search query parameters containing a name or phone fragment (`api-auth-design.md`, hardening) — they are PII; redact or hash before any access log, including proxy and ingress logs 04 controls.\n\n## What 04 does not decide (already decided upstream)\n\nToken TTLs and claim set (`api-auth-design.md`); scope vocabulary (`handoff-03-auth.md`, pending); password and client-secret hashing (`threat-model.md` Asset 1); whether the connector caches vendor tokens (`connector-security.md` §1 — it may, under the conditions in #6); PII retention windows (`../05-data-ops/pii-governance.md`).\n\n## Open items for the objection turn\n\n- Is anything in this table mis-owned between 02 (requirement), 03 (implements), and 04 (mechanism)?\n- Is a secret missing? Candidates I considered and excluded: session cookies (none — machine-to-machine API), SMTP/notification credentials (no such feature in scope), object-storage keys (no such component).\n- Is the env-var exception for #1 acceptable, or should 02 push 03 for a `_FILE` convention now?\n"

Those vendors are outside our control; we can only constrain what we do with what they return.\n6. **Trust boundary — deployment operator.** The design-only deployment target (`../04-infra-devops/`) is a Kubernetes lab cluster whose manifests would be applied by an external operator agent. Whoever can apply a manifest can read any Secret it mounts, so \"secrets are safe once they are in the cluster\" is an assumption about that operator, not a property of the design. Consequence, set as a requirement in `handoff-04-secrets.md`: manifests carry Secret names, never values; values are provisioned out-of-band; the operator's rights are documented, not hidden. Nothing is deployed and the operator is never contacted during this take-home."
