30	The structure above (root brief, five track briefs, scoped subagents) is the skeleton. What actually ran inside it, once Warren authorized hiring, was a second layer this project built on top of Anthropic's documented patterns rather than found in them: each of the five track leads hired a small sub-team of persona-bearing agents — this track hired four (Tomasz Wrede, an Adversary; Helena Marsh, a Principled Architect; Felix Adebayo, a Tinkerer and this lead's deliberate temperament opposite; Ingrid Solano, a Designated Skeptic) — and ran a small catalog of named orchestration patterns (red team/blue team, adversarial pair, structured written debate, independent second review, rotating devil's advocate, three hats) against specific design decisions, each ending in a durable decision file under `decisions/`. **This entire layer — the personas, the variance rules in `../CASTING.md`, the pattern catalog, the rule that every decision artifact records its own model/turn-count footer — is this project's own design, not an Anthropic-documented technique.** It's a deliberate, load-bearing extension built on top of the orchestrator-worker pattern (§"Orchestration" above), motivated by a specific risk Anthropic's own writing doesn't have to worry about but a five-lead org does: five track leads (and the PM) starting from the same base model land in the same temperament quadrant by default, and agreement between agents who all think alike is not evidence of a good decision.
31	
32	### What the pattern catalog actually bought, honestly measured
33	
34	This is not a claim that multi-agent debate produces better designs than a single strong session **in general** — that claim was itself put to a structured written debate in this track (S5, `decisions/ai-workflow-claim-debate.md`) and the ruling is reproduced faithfully below, including the position that lost ground. What can be stated and evidenced:
35	
36	- **S3 (red/blue, connector token lifecycle):** Tomasz's red seat produced five ranked attack leaves, each shaped as "add a control" (encrypt the cache harder, bind the token, rate-limit more). Felix's alternatives seat — a role that exists specifically to ask "does the thing being protected need to exist" rather than "is the control sufficient" — proposed deleting two of those leaves outright by removing the token cache entirely (fetch-per-call instead of cache-with-a-TTL), rather than hardening it. That's a concrete design change this document can point to that would not have existed without a seat whose brief was structurally different from the seat before it. Tomasz's own rebuttal turn then conceded two of the remaining three leaves cleanly (no new finding) and tightened the third — a fair count includes that clean concession as a null result, not just the hit. **Tally: 2 hits (deleted leaves), 1 tightening, 2 null (clean concessions).**
37	- **S8 (independent second review, three security-graded documents) — the most valuable process evidence in this track, worth stating as a general lesson rather than just an incident report.** `PLAN.md`'s original static roster assigned Helena to review both `threat-model.md` and `api-auth-design.md`. By the time S8 actually ran, that assignment was stale: Helena had since become S4's Proposer and authored the very scope-vocabulary and policy content in `api-auth-design.md` that S8 was meant to check, and had also been S3's blue seat authoring the controls in `connector-security.md`. Reviewing either would have been an author re-reviewing their own work under the label "independent review." **The lesson: independence is a property that has to be checked at the moment a review actually runs, not a role assigned once at planning time and trusted to still hold** — a five-track org where the same small hire roster accumulates authorship across successive debates will decay its own independence guarantees exactly this way if nobody re-checks before each review. Caught here before running (Helena reassigned to `threat-model.md` only, a document she never touched; Tomasz — clean, no Phase 2 involvement in this document — took `api-auth-design.md`; Ingrid kept `connector-security.md`, unaffected), not after.
38	
39	  With independence actually verified, the reviews earned their cost. **The concrete example worth leading with:** Tomasz found that the decomposition-resistant rate-limit counter S4 had just finished designing — specifically as Ingrid's own fix to her objection 4 in that same debate — was a silent no-op for `profile:read:any`, the scope with the broadest blast radius, because its exemption clause ("without a fresh `reason_code`") was unconditionally satisfied by a scope that already requires a `reason_code` on every call by design. Neither Helena (who wrote the fix) nor Ingrid (whose objection it answered) caught this, because both were reasoning inside "does this satisfy the objection as stated" — the same self-referential blind spot independent review exists to catch, now demonstrated on the review pattern's own prior output, one debate later. Ingrid's separate finding on `connector-security.md` — that a document entirely about protecting a vendor token's custody said nothing about who may call the connector holding it, or what the token authorizes once used — is a different class of question from the one the S3 red/blue run spent its effort on, for the same underlying reason: every S3 participant was already inside the "protect the token" frame. **Tally: 10 accepted findings across 3 documents, 0 declined, 0 null reviews** — a different, better hit rate than S3's, and both numbers belong in this document, not just the ones favorable to the claim.
40	- **Theo's Newcomer cold-read of `handoff-04-secrets.md` (04's track, not this one, but this track's document):** two real gaps (an undefined component's feature status, a trust-boundary reference that required reading a second track's file to parse) that survived this document's own author's review, caught by a reader with zero authorial investment. **1 hit.**
41	
42	### What the S5 debate actually settled — stated plainly, including the losing position
43	
44	Felix argued (Position A) that this evidence shows the pattern produces better designs than a single strong session would. Ingrid argued (Position B) that two data points, both produced by roles this project built specifically to produce exactly this kind of catch, are not evidence of a general effect — a single session working from an explicit checklist ("can this control's leaf be deleted instead," "get one cold read before shipping") could plausibly produce the same catches without four personas and a debate protocol, and nobody has run or estimated that comparison. The ruling (`decisions/ai-workflow-claim-debate.md`) went **against** the general claim and **for** a narrower one: the defensible statement is a structural/mechanism argument, not a statistical one — a seat holding a genuinely different optimization target, or a reader with no authorial stake, can surface a class of error that self-review structurally tends not to, because self-review interrogates the answer it already committed to rather than the frame that produced the question. That is not the same as asserting multi-agent design beats solo design as a population-level effect, and this document does not make that broader claim. Ingrid's insistence that null results (the S3 leaf conceded clean, S8's near-zero null rate by contrast) be counted in the same tally as hits was adopted outright and is reflected in the tallies above, not just the successes.

39	## Why this run mattered (for `ai-workflow-narrative.md`, S9)
40	
41	Every one of these six findings (4 in threat-model, 4 in api-auth-design — wait, tally below) survived because the reviewer had zero authorial investment in the document's existing frame. The `api-auth-design.md` finding 1 is the clearest case: the counter's flaw was invisible to Helena (who wrote it) and Ingrid (whose objection it was answering) precisely because both were reasoning inside "does this satisfy the objection as stated," not "does this control actually bind for every scope it claims to cover." Tomasz, arriving with no stake in either the original proposal or its revision, checked the mechanism against all three scopes independently and found the gap in under one review pass.
42	
43	**Tally, honestly counted (per S5's ruling that null results count too):** 4 + 4 + 2 = 10 findings across three documents, zero null reviews this time — every second-review seat found at least one real, accepted gap. This is a different (better) hit rate than S3's red/blue, where one of three top-ranked leaves (leaf 2 in S3) was conceded clean with no new finding. Both data points belong in S9's tally, not just the hits.

Fixed at the design level in `handoff-04-secrets.md` Assumption 2 and row 2: the issuer runs as a second Deployment of the same `api-service` image, selected by an environment variable (`APP_MODE=issuer` vs. default), with its own ServiceAccount that alone mounts the signing-key Secret. This story is the implementation and manifest work that design change requires — it did not exist as a story before the pass.\n\n**Acceptance criteria:**\n- [ ] `api-service` supports an `APP_MODE` environment variable selecting issuer vs. verifying behavior from one binary/image.\n- [ ] Two Kubernetes Deployments exist, each with its own ServiceAccount; only the issuer Deployment's pod spec mounts the JWT signing-key Secret — enforcement site: the manifest's volume mounts plus RBAC Role scoping `get`/`list` to the issuer's ServiceAccount.\n- [ ] The verifying Deployment's pod spec contains no reference to the signing-key Secret at all (not just RBAC-denied — physically absent from its mounts).\n- [ ] `containerization-design.md`'s mount at the lines the pass named is removed and replaced with the two-Deployment shape.\n\n**Depends on:** `handoff-04-secrets.md` v2 (this track); 03's `APP_MODE` config surface addition; 04's manifest change.\n\n**Model/effort:** sonnet, high (03 implementation); sonnet, high (04 manifest).\n\n**Type:** Story\n\n**Labels:** `track-02`, `security-graded`, `from-consistency-pass`, `no-code-yet`\n\n---\n\n## S13 — Wire `api-service`'s client credential to call the connector, and the vendor-token header pass-through\n\n**Status: open** (from `../decisions/cross-track-consistency.md` F3 and F15).\n\n**Description:** Two related gaps the pass found: (1) nothing said what our own `/auth` returns to its caller or how `/identity` obtains vendor authority, given the assignment's fixed `/identity` body has no credential field (F3) — resolved in `connector-security.md` §1: `/auth` returns the vendor token to the authenticated internal caller, which presents it as a request header (not body field) on the subsequent `/identity` call; the connector itself still never caches it. (2) `api-service` needs its own client credential to authenticate to the connector's now-required inbound auth (`connector-security.md` §5) in the first place, and no inventory row covered it — added as row 10 in `handoff-04-secrets.md` (F15). This story is the implementation work both design fixes require.\n\n**Acceptance criteria:**\n- [ ] `api-service` obtains and presents a `connector:identity-lookup`-scoped token (via its own client credential, row 10 of `handoff-04-secrets.md`) when calling `idp-connector`'s `/auth` and `/identity`.\n- [ ] The onboarding flow's vendor-auth step receives the vendor `access_token` from our `/auth` response and holds it only for the span between that call and the following `/identity` call — enforcement site: the handler/service layer that mediates the onboarding flow, not the connector itself (which remains stateless per S3).\n- [ ] `/identity` accepts the vendor token as a request header, not a body field, and fails closed with a generic error if it is missing or rejected by the vendor.\n- [ ] `01-product-industry-research-design/ux-notes.md`'s two-screen flow and this mechanism agree on what the frontend/onboarding-flow layer actually holds between screens (coordinate directly with Naomi if the UX description needs a one-sentence update to match).\n\n**Depends on:** `connector-security.md` (this track); `handoff-04-secrets.md` row 10 (this track); 03's connector-client implementation.\n\n**Model/effort:** sonnet, high.\n\n**Type:** Story\n\n**Labels:** `track-02`, `security-graded`, `from-consistency-pass`, `no-code-yet`"

24	- **Partner credential entry.** Username/password fields, framed as "sign in to `<provider>`," not the service's own login form — visually distinct, to signal whose credential this is.
25	- **Pre-filled review screen.** Name, phone, and address arrive already filled in from the `/identity` response; the user reviews and confirms rather than retyping. Fields are editable, not read-only — the provider is a starting point, not an irrevocable source of truth for this signup.

27	**The one design rule this surface enforces:** the partner's password is never visible to, or stored by, this service past the token exchange — the review screen never displays a password field, partner or otherwise, and nothing on this screen persists the credential entered on the previous one. That is the UI-level expression of the connector's `/auth` → `/identity` two-step: a short-lived token stands in for the password everywhere past the first screen.

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`.

39	Threat model, API auth/authz design, and connector security design are drafted:
40	
41	- `threat-model.md` — STRIDE-style analysis of `user_credential`, `user_profile`, and third-party `access_token` exposure, per-asset mitigations.
42	- `api-auth-design.md` — OAuth2 client-credentials grant with short-lived JWT bearer tokens and scoped, object-level authorization for question 2's search/retrieve API. Reasoned against static API keys and mTLS-only alternatives.
43	- `connector-security.md` — token handling, vendor-call authentication, and logging/persistence rules for question 3's `/auth` and `/identity` connector.
44	- `ai-workflow-narrative.md` — the full AI-tooling/workflow story for the submission, building on `research-claude-architecture-best-practices.md`.
45	- `planning-approach.md` — team-wide recommendation (requested by team-lead) for model/effort pairings per role, planning-phase coordination pattern, cross-track dependency order, and the shape/location of the shared planning artifact. Synthesized from all four other tracks' input plus this track's own view. Two follow-ups for this track surfaced from it, deferred until the planning pause lifts: a receiver-shaped 02→03 hand-off (token scheme and validation point, no alternatives discussion) and a 02→04 secrets inventory plus never-log list — the decisions exist in `api-auth-design.md` / `connector-security.md` but not yet in that form.

37:## Status
49:Phase 1 (org planning): `PLAN.md` in this directory is the track plan — eleven Stories, a four-hire roster (Adversary, Principled Architect, Tinkerer, Designated Skeptic), the debate plan, and dependencies; `../CASTING.md` §5 ratified with four ⟨02⟩ amendments; `planning-approach.md` gained Appendix A (attack-tree template) and Appendix B (harness constraints).
51:Phase 2 (execution): all four hires spawned and live as named teammates in this session. Completed: **S7** — `handoff-04-secrets.md` v1, Ingrid Solano's objection turn folded in (four objections, all accepted), sent to and cold-read by 04's Newcomer, two gating items fixed. **S3** — red/blue on the connector token lifecycle (Tomasz Wrede red, Felix Adebayo alternatives, Helena Marsh blue, Tomasz rebuttal, Marcus residual scoring); `connector-security.md` §1 rewritten to a no-cache-by-default posture with two hardened implementation controls (fresh auth header per request, explicit fetch-use-zeroize boundary); attack-tree table appended; full record in `decisions/connector-token-lifecycle-redblue.md`; residual all L except one accepted M (bearer-token replay, no vendor PoP lever), no follow-up Story required; handed to 03's opus token-lifecycle seat. **S4** — adversarial pair on search-API authz scoping (Helena proposes, Ingrid five numbered objections, Helena revises all five, Marcus rules); `api-auth-design.md` gained a finalized scope vocabulary, provisioning bars, object-level policy hook, decomposition-resistant rate limiting, and lifecycle-triggered revocation; full record in `decisions/search-authz-scoping.md`. **S6** — `handoff-03-auth.md` written and sent to Renata Cole (03): token scheme, validation point, S4's scope vocabulary, audit-log fields, "not yours to decide" list.
53:**All eleven Stories complete except S11** (post-implementation review, deferred to Warren's code go-ahead). S5 (`decisions/ai-workflow-claim-debate.md`) ruled against a general "multi-agent beats solo" claim and for a narrower, mechanism-level one, with the losing arguments preserved honestly. S8 (`decisions/second-review-security-docs.md`) required a mid-run reassignment when Helena's S4/S3 authorship broke her original independence on two of the three documents — caught and fixed before running, not after; ten accepted findings resulted, the sharpest being a decomposition-resistant rate-limit control from S4 that was a silent no-op for one of its two target scopes. S9 folded the org layer — personas, patterns, measured turn/model footers, S5's ruling stated plainly including the side that lost, the S8 reassignment as a general lesson ("independence is checked at review time, not assigned once"), and the real external operator agent named as deliberately out of scope — into `ai-workflow-narrative.md`. S10's two required fixes (repoint the wiped-schema reference, name the operator trust boundary) were already present in `threat-model.md` from earlier work; verified clean, no further edit needed.

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	- **No persistent or cached token, by default.** Revised by the S3 red/blue run (`decisions/connector-token-lifecycle-redblue.md`): the token is fetched fresh from `/auth` for each `/identity` call, held only inside that single request's execution scope, and discarded when the call returns — not written to any cache or datastore as a matter of course. Caching is an explicitly-justified exception requiring its own threat re-review if latency or vendor rate limits ever force the question; if that exception is ever opened, it must satisfy: (a) cache key derived from an immutable, vendor-issued identifier (our tenant id + vendor id + the vendor's own opaque subject id) — never from request-supplied `name`/`phone`, which are attacker-influenced; (b) TTL no longer than the vendor's own token expiry, encrypted at rest (envelope encryption via KMS, mechanics owned by `../04-infra-devops/CLAUDE.md`); (c) if the KMS/envelope key is unreachable at write or read time, fail closed to "no cache, fetch live" for that call — never to an unencrypted write and never to a hard connector failure.
20	- **Fetch-use-zeroize boundary, stated explicitly so it survives implementation:** the token variable's scope runs from the `/auth` response to the immediately following `/identity` call and no further; it is not passed up the call stack beyond the vendor-call function, and it is not reused across a retry. **A retried `/identity` call re-fetches via `/auth`; it never reuses a token held from a prior attempt** — otherwise the "one request" exposure window `§4`'s retry/backoff allowance quietly becomes "however long the retry policy runs." Go gives no guaranteed memory zeroing without unsafe/cgo, so a crash dump taken mid-call could still capture the token in the vendor-call function's stack; that residual is accepted given the window is now one function call, not a cache TTL (core-dump suppression at the runtime level is a `../04-infra-devops/CLAUDE.md` mechanism, requirement recorded here, not owned here). The token field is excluded from any generic request/response dump used in error handling — the same log-hygiene discipline below applies to panic traces and debug dumps, not just application logs.
21	- **The outbound HTTP client to the vendor must construct a fresh, isolated `Authorization` header per request, never inherited from connection reuse.** Connection pooling/keep-alive is the normal default in any HTTP client library; a pooled client that reuses a request-context object or fails to reset the auth header per call can attach request A's vendor token to request B's outbound call — the same cross-tenant leak as a cache-key collision, with no cache required. This is a required implementation discipline, not an assumption left implicit.
22	- **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.
23	- **Returned once, to the authenticated internal caller only — never to end users, never persisted server-side (resolved by the cross-track consistency pass, F3).** Our own `/auth` returns the vendor `access_token` to whichever authenticated `connector:identity-lookup`-scoped caller invoked it (in this project's shape, `cmd/api-service` acting on an onboarding flow's behalf) — this is what the assignment's `/auth` contract actually requires ("retrieves an `access_token`"), and it is what `../01-product-industry-research-design/ux-notes.md`'s onboarding flow depends on to bridge its two user-facing steps. Because our own `/identity` request body is fixed by the assignment to `{"phone", "name"}` with no credential field, the vendor token travels as a request header on the subsequent `/identity` call (e.g. `X-Vendor-Access-Token`) — this doesn't violate the fixed JSON contract, which governs the body only, not headers. The connector itself still never caches or persists the token (S3's no-cache ruling stands unchanged): each `/identity` call's presented token is used once and discarded, exactly as if it had been freshly fetched, and it is the caller's responsibility — not the connector's — to hold the token for the short span between the two calls. If a caller presents no token, or an expired one, `/identity` fails closed with a generic error that does not distinguish "no token" from "bad token" from "vendor rejected it" (same user-enumeration discipline as §4's other failure-handling rules).
24	
25	### 2. How `/identity` calls are authenticated to the vendor
26	
27	- 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).
28	- **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.
29	- **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).
30	- **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`.
31	
32	### 3. What this service should and shouldn't log or persist
33	
34	| Data | Log it? | Persist it? |
35	|---|---|---|
36	| 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 |
37	| End-user's vendor password (`/auth` request body) | **Never, under any circumstance, including error paths and stack traces** | **Never** |
38	| Vendor `access_token` | **Never** | Only as short-TTL encrypted cache per above; never in plaintext, never in application logs |
39	| 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 |
40	| 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 |
41	
42	### 4. Failure handling as a security control, not just reliability
43	
44	- **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.
45	- **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).
46	- **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.
47	
48	### 5. Authentication and authorization of calls *into* this connector
49	
50	Found by Ingrid Solano's S8 independent review — §1–§4 above are entirely about protecting the *vendor* token and the *vendor* call; none of them state who is allowed to call *our* `/auth` and `/identity` in the first place. Fixed here rather than left as a silent assumption:
51	
52	- **Callers of `cmd/idp-connector`'s own `/auth` and `/identity` must be authenticated**, using the same OAuth2 client-credentials → JWT bearer mechanism as `api-auth-design.md`, but with a **distinct audience** (`aud: idp-connector-service`, separate from `loginid-api-service`) and its own scope (`connector:identity-lookup`) — this is a different threat model and a different, smaller caller set (internal services, not question 2's broader API clientele), so it gets its own audience rather than reusing the search API's. Only a service that legitimately mediates an end-user or business flow needing vendor identity data (in this project's shape, `cmd/api-service` acting on a caller's behalf) should hold this credential — it is not exposed to arbitrary external callers.
53	- **Why this matters concretely:** without it, an unauthenticated caller could hit our `/auth` passthrough with arbitrary vendor credentials all day and use this connector as exactly the credential-testing oracle §4's rate-limit control is meant to prevent — but "rate-limited per calling-API-client" has nothing to bind "per calling-API-client" to if no caller identity is required to reach the endpoint at all.
54	- **Audit logging** for calls into this connector follows the same discipline as §3's table: caller `sub`, scope, timestamp, outcome — never the vendor credentials or PII in the request/response bodies.
55	
56	### 6. What a vendor token authorizes at `/identity` — an assumption, stated explicitly
57	
58	Also found by S8 review. This design's token-handling discipline (§1) is entirely about *custody* of the vendor token — encryption, memory scope, never-log. It says nothing about what the token is allowed to *do*: specifically, whether a vendor `access_token` obtained from one person's `/auth` call authorizes an `/identity` query for a *different* person's `name`/`phone`, or only for the token-holder's own identity.
59	
60	This connector cannot enforce that boundary itself — the assignment's generic `/identity` contract (`{"phone": "...", "name": "..."}`, no scoping field) puts that decision entirely on the vendor's own API. **Stated assumption, not a resolved control:** this design assumes a real ABC/XYZ-shaped vendor binds `/identity` queries to the authenticated principal at the vendor side (i.e., the vendor's own API rejects a query for an identity other than the token-holder's). If that assumption doesn't hold for a given real vendor, this connector becomes a lookup oracle for anyone who can obtain one valid vendor token, and no control in §1–§5 touches that risk, because none of them govern token *authority* rather than token *custody*. This is the same class of question as the search API's object-level authorization (`api-auth-design.md`, S4) and belongs on `../01-product-industry-research-design/CLAUDE.md`'s list when evaluating which real vendor ABC/XYZ represents — this track cannot resolve it without knowing a concrete vendor's actual token semantics.
61	
62	## What this design does not resolve
63	
64	- Data retention duration for cached `/identity` results — `../05-data-ops/CLAUDE.md`.
65	- Which secrets manager holds this connector's own vendor credentials — `../04-infra-devops/CLAUDE.md`.
66	- 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.

78	|---|---|---|---|---|---|---|---|---|
79	| 1 | Cache-key confusion → cross-tenant token/PII leak via request-derived cache key | Persistent cache (eliminated by default posture below) | M | H | **Eliminated by design:** no cache by default (Felix Adebayo, alternatives seat) — no persistent cache means no key to collide on. **Control, exception-path only:** if caching is ever re-opened, key must derive from immutable vendor-issued ids, never request-supplied `name`/`phone`. **Control (this run, Tomasz's rebuttal):** the connection-reuse variant of this leaf survives even with no cache — a pooled HTTP client that doesn't reset `Authorization` per call can attach one request's token to another. Closed with a required control: fresh, isolated auth header constructed per outbound request, never inherited from connection reuse. | 03 (client construction; cache-key derivation if exception ever opened) | **L** — storage variant eliminated; connection-reuse variant closed by an explicit, checkable implementation requirement | OWASP API8:2023; judgment (connection-reuse variant) |
80	| 2 | Fail-open on KMS unavailability during a caching window | Persistent cache with KMS-backed encryption at rest (eliminated by default posture) | M | H | **Eliminated by design:** no cache by default removes the write-time KMS dependency from the hot path. **Control, exception-path only:** if caching is ever re-opened, KMS-unreachable fails closed to "no cache, fetch live," never to an unencrypted write. Tomasz conceded this leaf outright — no hole found. | 03/04 (KMS mechanism is 04's) | **L** | NIST SP 800-57 |
81	| 3 | Vendor token replay — no proof-of-possession/session binding once decrypted for use | Token exfiltrated by any other means within its exposure window | M | H | **Accepted risk.** Bearer tokens under RFC 6750 are possession-equals-authorization by design; PoP/binding (DPoP, RFC 9449; mTLS-bound tokens, RFC 8705) needs vendor-side support this project cannot assume for a generic ABC/XYZ vendor the assignment never specifies. Acceptable *for this system* because fetch-per-call bounds the exposure window to one request's execution scope — no standing cached credential to steal. **Tightened per Tomasz's rebuttal:** the boundary is stated explicitly — fetch → use in the immediately following `/identity` call → zeroize; a retried `/identity` call re-fetches via `/auth` and never reuses a token from a prior attempt, so the accepted window cannot silently stretch to the length of the retry/backoff policy. | — (re-review trigger: a PoP-capable vendor surfacing in 01's research) | **M** — accepted, not eliminated; a real vendor-side constraint, not a design gap, but still "possession = authority" for the fetch's lifetime | RFC 6750 §5; RFC 9700 §2.5 |
82	| 4 | Process-memory/crash-dump exposure of the plaintext token before encryption | Attacker has read access to a crash artifact or swap on the host | L | M | **Control:** token field excluded from any generic request/response dump used in error handling (panic traces, debug dumps — same discipline as application logs); token variable scoped to the narrowest function possible, never passed up the call stack beyond the vendor-call function. **Residual accepted:** Go gives no guaranteed memory zeroing without unsafe/cgo, so a crash dump taken mid-call could still capture it; acceptable given the window narrowed from a cache TTL to one function call (Felix's alternatives turn). Core-dump suppression at the runtime level is a 04 mechanism, requirement recorded, not resolved here. | 03 (code discipline) / 04 (runtime config) | **L** — narrowed from a standing cache exposure to a single function-call window | OWASP Logging Cheat Sheet |
83	| 5 | Connector used as a credential-stuffing oracle against the vendor (rate-limit granularity unstated) | No per-identity/per-IP rate-limit granularity stated in the original design | M | M | **Control:** rate limit keyed per calling-API-client *and* per source IP, with a stricter threshold on vendor-auth *failure ratio* specifically (credential stuffing shows as a high failure ratio before high volume), paired with exponential backoff per identity attempted, not just per client — closes the granularity gap without adding a new requirement beyond what §4 already gestured at. | 03 (rate-limit logic) / 04 (shared rate-limit store or edge mechanism, if enforced at a gateway) | **L** | OWASP API4:2023; NIST SP 800-63B §5.2.2 |
84	
85	Rules of use followed: Tomasz ranked and handed over his top five before Helena answered (per `CASTING.md` §5 ⟨02⟩); Felix's alternatives turn sat between red and blue and eliminated leaves 1's storage variant and 2's substrate by design change rather than control; Helena answered every leaf with a control or a justified accepted risk; Tomasz's rebuttal turn on the top three surfaced one unaddressed variant (leaf 1's connection-reuse case) and one boundary needing explicit statement (leaf 3), both resolved without reopening the ruling; Marcus assigned Residual with the justification in each row. No Residual **H** — none of the five leaves cleared that bar after blue's response and the rebuttal-turn tightening, so no follow-up Story is required; leaf 3's **M** is the one residual worth Warren's attention as a genuine accepted risk, not a gap.

35	
36	**Why the two-call shape (`/auth` then `/identity`) is the right pattern, per Persona 3** (the onboarding flow that pre-fills a new user's profile from a third-party IDP at signup; see `personas-use-cases.md`)**:** it's a minimal, legacy-style token-exchange flow — trade a long-lived credential (username/password) for a short-lived, purpose-scoped token, then use that token for the actual data pull. This is structurally the same shape as OAuth2's **resource-owner-password-credentials (ROPC) grant** — one of several standard ways an OAuth2 client obtains a token, this one taking a raw username/password directly instead of redirecting the user to log in elsewhere — and it is the specific grant type RFC 9700 now states MUST NOT be used, in favor of authorization-code or client-credentials flows (see `research-oauth-history.md` for the OAuth lineage this pattern sits in). Recognizing that lineage matters for the write-up: this connector contract is not a novel design, it's a well-understood, industry-standard-but-dated pattern (see `industry-framing.md` §2, revised after the S2 debate on `PLAN.md` — see `decisions/password-baseline-debate.md` — this is named as the conventional baseline, not as a claim about the assignment author's intent).
37	
38	**Why the connector must be built provider-agnostic (ABC/XYZ as instances of one interface, not two bespoke integrations):** the assignment names the providers generically on purpose — this is a request to design *a connector interface*, with ABC and XYZ as its first two implementations, not to hardcode either one. Concretely, that means:
39	
40	- `Authenticate(username, password) → token` and `FetchIdentity(token, phone, name) → PII` are **the vendor adapter's internal interface, not the connector's exported operation** — per `../02-ai-security-architecture/connector-security.md`, the token never crosses the adapter boundary. The adapter's one exported method is a single identity-lookup call (e.g. `LookupIdentity(username, password, phone, name) → PII`) that performs auth-then-fetch internally; the calling code (the onboarding flow from Persona 3, above) never sees, holds, or passes a token between two calls of its own.
41	- Each provider adapter owns its own quirks (token expiry format, field-name differences, rate limits, error codes) behind that common interface — the calling code never branches on which provider it's talking to, and never touches the intermediate token either way.
42	- The interface's shape should anticipate that a future provider might not be username/password-based at all — an OAuth2/OIDC provider would satisfy `Authenticate` differently (redirect-based auth-code exchange instead of a direct password POST) but still ultimately produce a token this connector can use the same way for `FetchIdentity`. This is the connector-side equivalent of `user_credential.method`'s extensibility from §1 — flagged here, not built here, per `industry-framing.md`'s point about not burying the actual assignment under speculative scope.
43	
44	**Field-mapping note (product-level, not implementation):** the assignment's `/identity` response splits address into `street_address`, `locality`, `region`, `postal_code`, `country` — this is recognizably the OpenID Connect `address` claim shape (a widely-used standard structure for exactly this purpose), which is a useful fact for the write-up: it signals the assignment's own contract is already leaning on real industry convention rather than an arbitrary shape, which is worth naming explicitly as evidence of "this connector is meant to look like a real federated-identity integration," reinforcing the design choices above.

48	Three seams to build with deliberately, per this document: `user_credential.method` as a real discriminator (not a fixed enum), a search API designed around masked-by-default results + rate limiting + audit logging (not just an authenticated GET), and a provider-agnostic connector interface with ABC/XYZ as its first two adapters (not two copy-pasted integrations). Each seam is where this "before" baseline visibly points toward the "after" — passkeys, scoped search, and modern federated-identity providers — without this submission having to build any of the "after" itself.

50	## Contract summary for 03
51	
52	This section is the single-page version 03 should build against without re-reading the rest of this document. Where this section and the prose above conflict, this section is current.
53	
54	**Entities (Q1)** — exact assignment field names:
55	
56	- `user_profile`: `name`, `address`, `phone` (plus a primary key and the FK target for `user_credential`).
57	- `user_credential`: `username`, `method`, `password` (plus a primary key and a FK to `user_profile`).
58	- Relationship: **one `user_profile` to many `user_credential`** — do not model as 1:1. `method` is a real discriminator column (string/enum-with-room, not a fixed two-value enum) that determines which other columns on a `user_credential` row are meaningful; only the `"password"` method needs a password hash today. How that's physically modeled (nullable columns vs. method-specific side tables) is 03's and `../05-data-ops/CLAUDE.md`'s call, not fixed here.
59	
60	**REST API (Q2):**
61	
62	- `GET /profiles/{id}` — exact retrieval.
63	- `POST /profiles/search` — search, **not** `GET` with query params (rationale above). Request body shape: a top-level `expand: bool` field, sitting alongside the query fields (`name`, `phone`, partial-match flags), e.g. `{"name": "...", "phone": "...", "expand": false}` — not nested under a sub-object. Default (`expand` absent or `false`) returns masked/partial PII; `expand: true` requests full-field detail and, per the authz mechanism in `../02-ai-security-architecture/CLAUDE.md`, should require a more tightly-scoped credential than the base search call.
64	- Default response for search is masked/partial PII; `expand: true` is required for full-field detail and should be more tightly scoped than the base search call (same field, same meaning, as above).
65	- Search is rate-limited and paginated, independently of retrieval-by-ID.
66	- Every search call must be attributable and audit-logged (caller identity, query, timestamp) — the API shape must not make call attribution an afterthought (e.g., no anonymous/stateless-only search path).
67	- Authn/authz mechanism (API key vs. OAuth2 client-credentials vs. mTLS, token formats, scopes) is fully specified in `../02-ai-security-architecture/CLAUDE.md` — 03 implements against that document's design, not against an invention of its own.
68	
69	**Connector interface (Q3):**
70	
71	- Endpoints, methods, and JSON bodies for `/auth` and `/identity` are fixed by the assignment (see root `CLAUDE.md`) — 03 does not re-specify them.
72	- Build one provider-agnostic interface with ABC and XYZ as its first two adapters. `Authenticate` and `FetchIdentity` are internal to each adapter, not exported — the adapter's one exported method (e.g. `LookupIdentity(username, password, phone, name) → PII`) performs auth-then-fetch inside itself, so the vendor token never crosses the adapter boundary, per `../02-ai-security-architecture/connector-security.md`. The calling code (onboarding flow) never branches on provider identity and never holds a token itself.
73	- `/identity` PII response fields (`name`, `phone`, `street_address`, `locality`, `region`, `postal_code`, `country`) match the assignment exactly; the address sub-shape matches the OIDC Core `address` claim (`research-oidc-address-claim.md`) — reuse those member names verbatim in Go structs, do not rename them.
74	- Leave the interface's `Authenticate` signature able to accommodate a future non-password-based provider (e.g., OAuth2/OIDC redirect flow) without redesigning `FetchIdentity` — flagged as a design constraint on the interface shape, not something to build now.
75	
76	**Out of scope for 03 — do not re-derive, read the owning track instead:**
77	
78	- The authn/authz *mechanism* for the search/retrieve API — `../02-ai-security-architecture/CLAUDE.md`.
79	- How `user_credential.method`'s discriminator is physically modeled (columns vs. side tables) and all schema/migration decisions — `../05-data-ops/CLAUDE.md`.

Caching is an explicitly-justified exception requiring its own threat re-review if latency or vendor rate limits ever force the question; if that exception is ever opened, it must satisfy: (a) cache key derived from an immutable, vendor-issued identifier (our tenant id + vendor id + the vendor's own opaque subject id) — never from request-supplied `name`/`phone`, which are attacker-influenced; (b) TTL no longer than the vendor's own token expiry, encrypted at rest (envelope encryption via KMS, mechanics owned by `../04-infra-devops/CLAUDE.md`); (c) if the KMS/envelope key is unreachable at write or read time, fail closed to \"no cache, fetch live\" for that call — never to an unencrypted write and never to a hard connector failure.\n- **Fetch-use-zeroize boundary, stated explicitly so it survives implementation:** the token variable's scope runs from the `/auth` response to the immediately following `/identity` call and no further; it is not passed up the call stack beyond the vendor-call function, and it is not reused across a retry. **A retried `/identity` call re-fetches via `/auth`; it never reuses a token held from a prior attempt** — otherwise the \"one request\" exposure window `§4`'s retry/backoff allowance quietly becomes \"however long the retry policy runs.\" Go gives no guaranteed memory zeroing without unsafe/cgo, so a crash dump taken mid-call could still capture the token in the vendor-call function's stack; that residual is accepted given the window is now one function call, not a cache TTL (core-dump suppression at the runtime level is a `../04-infra-devops/CLAUDE.md` mechanism, requirement recorded here, not owned here). The token field is excluded from any generic request/response dump used in error handling — the same log-hygiene discipline below applies to panic traces and debug dumps, not just application logs.",
  "new_string": "- **No persistent or cached token, by default — updated for F3's caller-holds-the-token model (seam re-run regression fix).** The S3 ruling's no-cache posture stands, but its original wording assumed the connector itself calls `/auth` immediately before every `/identity` call, chaining the two internally. That's superseded by F3: our own `/auth` and `/identity` are genuinely separate calls from our caller's perspective (matching the assignment's fixed two-endpoint contract), and it is the **caller** (`api-service`, on the onboarding flow's behalf) that calls our `/auth`, receives the vendor token, and presents it as a header on the following `/identity` call. What the connector still never does: cache or persist the token, write it to any datastore, or hold it any longer than the single request currently being handled. The connector's `/identity` handler uses whatever token its caller presents for that one call and discards it when the call returns — the \"no cache\" discipline now describes the connector's own handling of a caller-presented token, not a connector-managed fetch-then-cache cycle. Caching is still an explicitly-justified exception requiring its own re-review if it's ever proposed for either side of this exchange; the exception conditions (immutable cache key, TTL, KMS fail-closed) from the S3 ruling are unchanged if that question is ever reopened.\n- **Fetch-use-zeroize boundary, restated for the caller-holds-the-token model:** on the `/identity` side, the presented token's scope runs from the point the handler reads it off the request header to the end of that single call, and no further — it is not cached, not passed to any other request, not logged. On the `/auth` side, the token returned to the caller is not retained by the connector after the response is sent. **Retry behavior is now the caller's responsibility, not the connector's**: if `api-service` retries a `/identity` call, whether it re-presents the same token or first calls `/auth` again is its own policy decision based on the token's likely freshness — the connector's only obligation is to treat each presented token as freshly supplied and reject it cleanly (fail closed, generic error) if the vendor rejects it, never silently retrying the vendor call with a stale token on the connector's own initiative. Go gives no guaranteed memory zeroing without unsafe/cgo, so a crash dump taken mid-call could still capture the token in the handler's stack; that residual is accepted given the window is one request, not a cache TTL. The token field is excluded from any generic request/response dump used in error handling — the same log-hygiene discipline below applies to panic traces and debug dumps, not just application logs."

/Users/warrenthompson/Source/LoginID/02-ai-security-architecture/handoff-03-auth.md:3:Status: **v3** — updated after the cross-track consistency pass (`../decisions/cross-track-consistency.md`) resolved six findings owned by this track that touched this hand-off (F3, F5, F6, F8, F10, F-pag, F52); v2's S8-driven fixes are unchanged and folded in below as before. Receiver: Renata Cole, `../03-engineering-delivery/`.

117	
118	**Status: done** (`handoff-03-auth.md`, v2 after S8 revisions).
119	
120	**Description:** Synthesized S4's ruling and the token-shape decisions in `api-auth-design.md` into a receiver-shaped hand-off Renata Cole can build against without re-deriving this track's reasoning: token scheme, where it's validated, the final scope vocabulary and object-level policy hook, pagination/rate-limit numbers, the audit-log field list, and an explicit "not yours to decide" list. Revised to v2 after S8's independent review surfaced two implementation-relevant fixes (the decomposition counter's scope-coverage gap; the connector's own inbound-auth requirement). Accepted by 03 with a confirmed `authorize()` placement (in-handler, not middleware) and `DB_DSN_FILE` folded into the config surface.
121	
122	**Acceptance criteria:**
123	- [x] Receiving track (03) can act on this without re-deriving the reasoning in `api-auth-design.md`/`connector-security.md` — confirmed by Renata directly, cold read "clean."
124	- [x] Token TTL (5–15 min), no refresh, no denylist — enforcement site: `exp` claim check in the verification middleware; absence of a refresh-grant or denylist-lookup code path.

143	**Status: done** (`handoff-04-secrets.md`, v1).
144	
145	**Description:** Authored the secrets inventory and never-log list Theo Bergman's track needs to design secrets delivery against, then ran Ingrid Solano's single objection turn (S7's assigned pattern — one turn, not a full debate) and folded in all four accepted objections: the authorization-server's ownership was mis-scoped by omission, a KMS-access credential row was missing, the `DB_DSN` env-var exception was too weak, and audit-log read access needed its own RBAC line distinct from Secret access. Cold-read by 04's Newcomer (Wesley Okonkwo) caught two further gating gaps (TOTP/token-cache feature-status ambiguity; a non-self-contained trust-boundary reference), both fixed.

71	- **TLS 1.2+ only**, terminated in front of the API; no plaintext.
72	- **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).
73	- **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.
74	- **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.
75	- **Token-endpoint brute-force protection — S8 review addition (Tomasz Wrede).** Every rate limit above protects the resource API *after* a token is issued; none of them protect the token endpoint itself, where a caller presents `client_id`/`client_secret` to obtain one. Require: failed-grant rate limiting and progressive backoff per `client_id` and per source IP, and alerting on a sustained run of failed grants against one `client_id` — the same discipline `threat-model.md` Asset 1 applies to password brute-force, applied here to the client-credentials grant, which had no equivalent control stated. Client-secret entropy and storage are `04-infra-devops`'s and this document's own hashing requirement respectively; the token endpoint's own request-level defense is this document's gap to close.
76	
77	## Why not "just API keys"
78	
79	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	# Hand-off 02 → 03: Auth scheme, validation point, and authorization requirements
2	
3	Status: **v3** — updated after the cross-track consistency pass (`../decisions/cross-track-consistency.md`) resolved six findings owned by this track that touched this hand-off (F3, F5, F6, F8, F10, F-pag, F52); v2's S8-driven fixes are unchanged and folded in below as before. Receiver: Renata Cole, `../03-engineering-delivery/`. Written so 03 should be able to scaffold and build the middleware without re-deriving the reasoning in `api-auth-design.md`, `connector-security.md`, or the S3/S4/S8 decision records. Full reasoning, if wanted: `api-auth-design.md`, `decisions/search-authz-scoping.md`, `decisions/connector-token-lifecycle-redblue.md`.
4	
5	## Token scheme
6	
7	- **Grant type:** OAuth2 client-credentials. Machine-to-machine only; no end-user login flow for question 2's API.
8	- **Token format:** JWT, signed, asymmetric (RS256 or ES256 — pick one and use it consistently; RS256 is the safer default if your Go JWT library's ES256 support is less mature).
9	- **Claim set (minimum):** `sub` (calling client identity), `scope` (space-delimited, values below), `exp`, `iat`, `aud` (this API, specifically — reject tokens minted for another audience).
10	- **Literal values, filling the "pending 02's final scheme" placeholder in your Service boundaries config surface:** `AUTH_JWT_ISSUER = "https://auth.loginid-takehome.internal"`, `AUTH_JWT_AUDIENCE = "loginid-api-service"`. Both are configuration, not secrets — safe in a `ConfigMap` or committed default, per `handoff-04-secrets.md` row #3.
11	- **TTL:** 5–15 minutes. No refresh tokens — the client re-authenticates with its own client secret on expiry.
12	- **No denylist.** Revocation is handled by TTL shortness, not a stateful lookup. Don't build one; it's not missing, it's a deliberate trade-off already reasoned through in `api-auth-design.md`.
13	- **Verifier must pin the expected algorithm** (whichever of RS256/ES256 you choose) and reject a token whose header claims any other algorithm, including `alg: none` and a downgrade to a symmetric algorithm using the public key as an HMAC secret (RFC 8725 §3.1). Check your JWT library's default behavior — several popular libraries have shipped this vulnerability by not doing this by default.
14	- **Token-endpoint brute-force protection**, separate from the resource-API rate limits below: failed-grant rate limiting and progressive backoff per `client_id` and per source IP on the token-issuing endpoint itself, plus alerting on a sustained run of failed grants against one `client_id`. This protects the endpoint where a caller presents `client_id`/`client_secret`, which none of the resource-API limits below cover.
15	- **Bearer-token replay is an accepted risk, not a gap to close in implementation.** This token has the same possession-equals-authority property as the connector's vendor token (`connector-security.md`); no PoP/binding is expected or required here. Noted so it isn't mistaken for something to "fix" during implementation.
16	
17	## Where it's validated
18	
19	- **Middleware at the API edge**, in `internal/api/` per your published service boundary — every request to `cmd/api-service` passes through token validation before reaching a handler. `cmd/idp-connector` does not validate *this* token — but per `connector-security.md` §5 (added by S8 review), `idp-connector`'s own `/auth` and `/identity` handlers need the same JWT middleware pattern, with a **distinct audience** (`aud: idp-connector-service`, not `loginid-api-service`) and its own scope (`connector:identity-lookup`), restricted to internal callers (in this project's shape, `api-service` acting on a caller's behalf) — not the same token, not exposed to arbitrary external callers. Two audiences, one mechanism.
20	- **Key retrieval:** middleware verifies with the **public** key only (JWKS or a fetched public key — see `handoff-04-secrets.md` row #3). The private signing key never touches the verifying `api-service` Deployment; it lives with the token-issuing function, which is a mode of the same `api-service` image but runs as its **own Deployment** (`APP_MODE=issuer`, its own ServiceAccount), not the same Deployment doing both (corrected in `handoff-04-secrets.md` Assumption 2 and row #2, F13 — RBAC on a Secret's `get` verb doesn't stop a volume already mounted into a shared Deployment's containers, so the separation has to be a second Deployment, not RBAC alone). This is a second `APP_MODE` value for you to wire alongside your existing config surface.
21	- **Key rotation:** expect a `kid` claim; publish old and new public keys together during rotation overlap. Token TTL (5–15 min) bounds how long that overlap needs to last.

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	Priya's prose schema in `../05-data-ops/multi-db-strategy.md` (the `.sql` files were deliberately wiped with the rest of the code on 2026-09-12; the prose contract is the source of truth until Warren's code go-ahead) gives `user_credential` three columns for this purpose: `secret` (nullable, bytes holding the PHC-encoded hash string — `BYTEA`/`BLOB`, Go `[]byte`; corrected by the cross-track consistency pass, F34 — this was previously described here as "nullable TEXT," which is wrong against the landed contract type; 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 current recommendation, consistent with NIST SP 800-63B Rev. 3's requirement of a memory-hard one-way key derivation function (800-63B Rev. 3, currently in force, requires a "suitable" memory-hard KDF without naming Argon2id specifically by name; Argon2id-by-name guidance appears in the SP 800-63-4 draft revision, not yet final — cited precisely rather than invoking "NIST recommends Argon2id" as if it were settled text). 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 bytes — 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	6. **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.

7	1. Deployment target is 04's **real Kubernetes lab cluster, reachable behind a public tunnel** (Warren's implementation go-ahead, 2026-09-12 — updated from a design-only reference). 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. **The repository is now public** (`https://github.com/wtvamp/loginid-takehome`) — every requirement in this document that says "never in source or committed config" is now categorical, with no private-repo safety net.
8	2. 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. **The token-issuing authorization-server function is a mode of `api-service`, not a third binary** — this take-home's scope doesn't justify a standalone authz server, and 03 has published no third `cmd/` entrypoint. **Corrected by the cross-track consistency pass (F13):** "a mode of the same binary" is not "the same Kubernetes Deployment," and the earlier text here was wrong to imply RBAC alone separates them — a Kubernetes Role restricting `get` on a Secret has no effect on a volume already mounted into a container, so if `api-service`'s one Deployment mounted the signing key, every replica (verification path included) would have it on disk regardless of RBAC. **The fix: the issuer runs as a second Deployment of the same `api-service` image**, selected by an environment variable 03 adds to the config surface (e.g. `APP_MODE=issuer` vs. the default, consistent with the surface's env-var-only, no-flags rule), with **its own ServiceAccount that alone mounts the signing-key Secret** (row #2) — the `api-service` Deployment serving verification/search mounts nothing from row #2. This is a request into 03's Deployment/mode surface, not a unilateral change on my part; flag to me if the mode-selection mechanism needs to differ.
9	3. An **external operator agent** — a human or automated actor outside this project, holding cluster-admin or namespace-admin rights on 04's real lab cluster, who applies Kubernetes manifests to it — 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` Assumption 7, not a silent assumption; nothing further about who that operator is needs to be re-derived from 04's own files to act on this hand-off. As of this update, 04 has not yet made contact with that operator or deployed anything — `threat-model.md` carries the dated status.
10	4. 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.

28	## The org layer: personas, patterns, and debates (added after Phase 2 execution)
29	
30	The structure above (root brief, five track briefs, scoped subagents) is the skeleton. What actually ran inside it, once Warren authorized hiring, was a second layer this project built on top of Anthropic's documented patterns rather than found in them: each of the five track leads hired a small sub-team of persona-bearing agents — this track hired four (Tomasz Wrede, an Adversary; Helena Marsh, a Principled Architect; Felix Adebayo, a Tinkerer and this lead's deliberate temperament opposite; Ingrid Solano, a Designated Skeptic) — and ran a small catalog of named orchestration patterns (red team/blue team, adversarial pair, structured written debate, independent second review, rotating devil's advocate, three hats) against specific design decisions, each ending in a durable decision file under `decisions/`. **This entire layer — the personas, the variance rules in `../CASTING.md`, the pattern catalog, the rule that every decision artifact records its own model/turn-count footer — is this project's own design, not an Anthropic-documented technique.** It's a deliberate, load-bearing extension built on top of the orchestrator-worker pattern (§"Orchestration" above), motivated by a specific risk Anthropic's own writing doesn't have to worry about but a five-lead org does: five track leads (and the PM) starting from the same base model land in the same temperament quadrant by default, and agreement between agents who all think alike is not evidence of a good decision.

30	## Kubernetes-specific requirements (04 implements; 02 sets)
31	
32	- **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.
33	- **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.
34	- **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.
35	- **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.
36	- **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.
37	- **Audit/access logs (the output of the never-log list below) are readable only by an incident-review role, distinct from and narrower than general operator access.** `sub`, scope, record id, and timestamp are enough on their own to reconstruct who looked up whom — that log stream needs its own read restriction, separate from whichever service account can `get`/`list` the Secrets in this table. Mechanism (log-pipeline RBAC, a separate log sink with its own access control, etc.) is 04's call; the requirement is that "can read Secrets" and "can read the audit trail" are not the same grant.

(1) alone is operational hygiene, not an enforced boundary — a broad, unscoped Role verb still reaches any Secret that exists in the namespace regardless of who created it; (2) is the actual RBAC control, and is the one to name as the enforcement site in a review. If maintaining a `resourceNames` allow-list becomes unworkable as the Secret count grows, the fallback is putting the signing-key Secret in a separate namespace the deployer Role has no grant over at all — 04's call which of the two shapes fits the manifest set better, but one of them must be in place before this is called done."

59	- **Opaque cursor at the API boundary** (reasoning corrected by the cross-track consistency pass, F-pag): the earlier claim that offset paging itself "turns a capped page size into full-table enumeration" was wrong — a keyset cursor permits the identical page-by-page walk, just statefully. The actual control against decomposition-style enumeration is the cumulative distinct-record-touch counter below, not the paging scheme. The API's cursor is opaque to the caller and may encode 05's DAO-layer `Offset int` directly — the boundary property this API needs (callers can't construct or walk a page index by hand) holds regardless of what the DAO does underneath. Default page 20, hard ceiling 50 at the API boundary (05's DAO ceiling of 10,000 is not exposed).
60	- **Per-client-credential rate limits**: 60 req/min for `read:own`/`read:any`, 10 req/min for `profile:search`.
61	- **Cumulative distinct-record-touch counter per caller per rolling window** (e.g., no more than N distinct profiles returned to one credential per 24h), tracked independently of per-minute rate. A single-request cap and per-minute throttling only stop single-request or bursty enumeration; a caller staying under both limits can still walk the namespace in slices and reassemble the population over time (decomposition) — this counter is what catches that pattern regardless of how slowly it's spread. Counting-store mechanism is 03/04's to build; the requirement that volume is measured cumulatively, not just per-minute, is set here.
62	  - **Applies to `profile:read:any` as well as `profile:search`, unconditionally on `reason_code` presence — S8 review fix (Tomasz Wrede).** The original wording ("without a fresh `reason_code`/justification") made the counter a no-op for `read:any`, because `read:any`'s object-level policy hook already requires a `reason_code` on *every* call — so every `read:any` request trivially satisfied the exemption, and a compromised-but-legitimate `read:any` credential could walk the entire table one id at a time, tagging every call with the same reason code, and never trip the counter. The counter now applies to `read:any` regardless of whether a `reason_code` is present; a valid, non-repeating reason code does not exempt a caller from the cumulative cap, only from the *per-call* policy check. This closes the gap for the scope with the broadest blast radius (no referral constraint), which nobody in S4's adversarial pair was looking at from this angle.
63	- Sustained near-limit usage on any of the above alerts, not just hard-blocks at the ceiling.

An alert-only reading would make the counter a detection mechanism rather than the control it was built to be, and would recreate the \"attribution stands in for volume control\" gap it exists to close (S4 objection 4) — a caller who's crossed the cap and keeps getting served has no real cap.

Does `APP_MODE` genuinely separate the paths, not just branch inside one shared handler?** Yes, at the level this diff can actually prove. `resolveSigningKeyPath` early-returns `\"\", nil` when `appMode != \"issuer\"` — verifier mode never calls `os.Getenv(\"JWT_SIGNING_KEY_FILE\")`, never calls `os.Open`, never touches the file. `TestLoad_VerifierModeIgnoresSigningKeyFile` proves this directly, including the adversarial case (variable set anyway, verifier still ignores it) — that's the right test, not just a happy-path one. The primary security boundary is correctly stated as living on 04's side (the verifying Deployment's pod spec never mounts the Secret); this code is defense-in-depth on top of that, and says so in its own comments rather than overclaiming to be the boundary itself. Correct framing.\n\n**2. Zero reference to the private key in the verifying binary's reachable path?** Currently trivially true, because no signing/crypto code exists yet at all — `issuerPlaceholderHandler` does no cryptography and holds no reference to `Config.JWTSigningKeyPath`, and says so in comment. **Forward-looking note for LT-40, not a defect here:** when real issuance lands, the signing code must stay behind the same `appMode == \"issuer\"` gate at the point of use — not hoisted into a package-level `var`/`init()` that reads the file unconditionally at process start. Worth stating as an explicit acceptance criterion on LT-40 rather than assumed.\n\n**3. `kid`/rotation, per `handoff-03-auth.md`'s \"expect a `kid` claim; publish old and new public keys together during overlap\":** absent, and correctly so — this PR is scaffolding only, its own comments defer real issuance (and by extension `kid`) to LT-40. Confirming rather than flagging: nothing here contradicts the rotation requirement, it's just not this story's job.\n\n**4. Minor observation, not a blocker:** `Config` now carries `JWTSigningKeyPath`, a path to secret-bearing material. It's low sensitivity on its own (a path, not the key), but if any future debug/health route ever dumps `Config` verbatim, that path leaks. Recommend a rule now, before it's convenient to forget: `Config` is never logged/dumped wholesale, consistent with the never-log discipline already set for the key itself.\n\n**5. `APP_MODE` validation (reject unknown values as a startup error) and the readable-file check at startup rather than at first use** are both correct, tested from both directions (unset, unreadable, valid), and match the \"loud misconfiguration, not silent fallback\" principle this track has argued for elsewhere.\n\nNo blocking findings. Approve, with the one forward note for LT-40 above.\n\n---\nIndependent review: Helena Marsh (02 Principled Architect) — approve; APP_MODE/config split correctly keeps the verifying path from ever touching the signing-key file (proven by test, not just by inspection), issuer/rotation/`kid` correctly deferred to LT-40 per this story's own non-goals; one forward-looking note that LT-40's real signing code must stay gated behind `appMode == \"issuer\"` at point of use rather than hoisted to package init, and one minor note that `Config` should never be logged wholesale now that it carries a secret-file path.\nEOF\ngh pr comment 18 --repo wtvamp/loginid-takehome --body-file /tmp/helena-review-pr18.md",

/Users/warrenthompson/Source/LoginID/02-ai-security-architecture/threat-model.md:22:7. **Trust boundary — deployment operator (dated update, 2026-09-12: first deploy is live).** The deployment target is a **shared production cluster**, reached via a plain nginx Ingress + cert-manager on the cluster's shared LoadBalancer (DNS CNAME to `uplifttech.ddns.net`), public at `https://loginid-takehome.uplifttech.org` — no tunnel involved; 04 deploys with **direct `kubectl`** from a **repo-scoped GitHub Actions Runner Controller (ARC) runner authenticated via a GitHub App**. This is a real deployment, not a hypothetical: the trust boundary named below is now live, not a design-time assumption. 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 the operator (here, effectively the CI pipeline's own deploy identity), 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 CI deploy ServiceAccount itself is now a named instance of this trust boundary** (Tobias Lindqvist's finding): a namespace-scoped Role granting it Secret verbs for app-Secret management would, unless explicitly restricted, also let it read the JWT signing-key Secret — a path from "CI runner compromised" to "mint tokens" that this document did not previously name because there was no live CI deployer to name. Required controls in `handoff-04-secrets.md`: the signing key created out-of-band, and the deployer Role's Secret verbs scoped by `resourceNames` (or a separate namespace) to exclude it. **Because this cluster is shared, not dedicated to this project**, the operator boundary also now includes whoever else has rights on that cluster outside this project's own manifests — a fact worth naming rather than assuming the cluster's blast radius is scoped to this app alone; 04 owns whether that shared-tenancy risk needs any further narrowing (e.g., NetworkPolicy, namespace isolation) beyond what this document already requires.
/Users/warrenthompson/Source/LoginID/02-ai-security-architecture/backlog.md:262:**Description:** The pass caught a real contradiction: `handoff-04-secrets.md` said the JWT signing private key "never touches `api-service`" while also defining the issuer as "a mode of `api-service`," and 04's manifest resolved that by mounting the signing key into every replica of a single `api-service` Deployment — RBAC on a Secret's `get` verb does nothing to stop a volume already mounted into a running container. Fixed at the design level in `handoff-04-secrets.md` Assumption 2 and row 2: the issuer runs as a second Deployment of the same `api-service` image, selected by an environment variable (`APP_MODE=issuer` vs. default), with its own ServiceAccount that alone mounts the signing-key Secret. This story is the implementation and manifest work that design change requires — it did not exist as a story before the pass.
/Users/warrenthompson/Source/LoginID/02-ai-security-architecture/backlog.md:266:- [ ] Two Kubernetes Deployments exist, each with its own ServiceAccount; only the issuer Deployment's pod spec mounts the JWT signing-key Secret — enforcement site: the manifest's volume mounts plus RBAC Role scoping `get`/`list` to the issuer's ServiceAccount.
/Users/warrenthompson/Source/LoginID/02-ai-security-architecture/handoff-04-secrets.md:8:2. 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. **The token-issuing authorization-server function is a mode of `api-service`, not a third binary** — this take-home's scope doesn't justify a standalone authz server, and 03 has published no third `cmd/` entrypoint. **Corrected by the cross-track consistency pass (F13):** "a mode of the same binary" is not "the same Kubernetes Deployment," and the earlier text here was wrong to imply RBAC alone separates them — a Kubernetes Role restricting `get` on a Secret has no effect on a volume already mounted into a container, so if `api-service`'s one Deployment mounted the signing key, every replica (verification path included) would have it on disk regardless of RBAC. **The fix: the issuer runs as a second Deployment of the same `api-service` image**, selected by an environment variable 03 adds to the config surface (e.g. `APP_MODE=issuer` vs. the default, consistent with the surface's env-var-only, no-flags rule), with **its own ServiceAccount that alone mounts the signing-key Secret** (row #2) — the `api-service` Deployment serving verification/search mounts nothing from row #2. This is a request into 03's Deployment/mode surface, not a unilateral change on my part; flag to me if the mode-selection mechanism needs to differ.

Two controls required together, not either/or: (1) **the signing-key Secret is created out-of-band**, in a one-time `bootstrap.yaml` applied outside the CI-managed manifest set (by a human or a separate, more privileged process) — so under normal operation CI never needs a verb on it at all; (2) **the deployer Role's `secrets` verbs are scoped with `resourceNames`** to an explicit allow-list of the app Secrets CI is meant to manage, which never includes the signing-key Secret's name. (1) alone is operational hygiene, not an enforced boundary — a broad, unscoped Role verb still reaches any Secret that exists in the namespace regardless of who created it; (2) is the actual RBAC control, and is the one to name as the enforcement site in a review. If maintaining a `resourceNames` allow-list becomes unworkable as the Secret count grows, the fallback is putting the signing-key Secret in a separate namespace the deployer Role has no grant over at all — 04's call which of the two shapes fits the manifest set better, but one of them must be in place before this is called done.

258	## S12 — Split the token issuer into its own Deployment with isolated signing-key custody (LT-32)
259	
260	**Status: open** (from `../decisions/cross-track-consistency.md` F13).
261	
262	**Description:** The pass caught a real contradiction: `handoff-04-secrets.md` said the JWT signing private key "never touches `api-service`" while also defining the issuer as "a mode of `api-service`," and 04's manifest resolved that by mounting the signing key into every replica of a single `api-service` Deployment — RBAC on a Secret's `get` verb does nothing to stop a volume already mounted into a running container. Fixed at the design level in `handoff-04-secrets.md` Assumption 2 and row 2: the issuer runs as a second Deployment of the same `api-service` image, selected by an environment variable (`APP_MODE=issuer` vs. default), with its own ServiceAccount that alone mounts the signing-key Secret. This story is the implementation and manifest work that design change requires — it did not exist as a story before the pass.
263	
264	**Acceptance criteria:**
265	- [ ] `api-service` supports an `APP_MODE` environment variable selecting issuer vs. verifying behavior from one binary/image.
266	- [ ] Two Kubernetes Deployments exist, each with its own ServiceAccount; only the issuer Deployment's pod spec mounts the JWT signing-key Secret — enforcement site: the manifest's volume mounts plus RBAC Role scoping `get`/`list` to the issuer's ServiceAccount.
267	- [ ] The verifying Deployment's pod spec contains no reference to the signing-key Secret at all (not just RBAC-denied — physically absent from its mounts).
268	- [ ] `containerization-design.md`'s mount at the lines the pass named is removed and replaced with the two-Deployment shape.
269	
270	**Depends on:** `handoff-04-secrets.md` v2 (this track); 03's `APP_MODE` config surface addition; 04's manifest change.
271	
272	**Model/effort:** sonnet, high (03 implementation); sonnet, high (04 manifest).

Verified by Helena's PR review (reading the manifest/config, not just the claim).\n- [x] **Accepted residual risk, named explicitly (found by Naomi Voss/Desmond Okafor during LT-32 refinement, mitigation proposed by Theo Bergman):** the CI deployer's Role grants `create`/`update`/`patch` on `deployments` (required for the pipeline to function at all), and a Deployment volume-mount reference doesn't require the applying identity to hold RBAC on the referenced Secret — so a manifest PR could add a `volumeMount` for the signing-key Secret directly into the verifying Deployment, and the CI runner's existing deploy-write access would be sufficient to apply it, bypassing the Secrets-RBAC lockdown entirely without ever touching the Secrets API. No admission controller (Gatekeeper/Kyverno/OPA) exists on this cluster, and standing one up is disproportionate for this take-home. **Accepted, not a gap left silent, because:** (1) this is a structural property of Kubernetes RBAC without a policy engine — it applies to every Secret in the namespace, not uniquely to this one, and is a known, widely-accepted limitation of RBAC-only clusters; (2) the CI deploy identity is already this track's named privileged trust boundary (`threat-model.md` Assumption 7) — this is a concrete instance of a boundary already named, not a new one; (3) a compensating control exists: a CI check greps the manifest set for the signing-key Secret's name and fails the build if it appears outside the issuer Deployment's own block — a detective control that raises the bar (catches an accidental or careless PR before merge) without claiming to be a structural guarantee (a deliberately obfuscated reference could still evade a grep). This is stated as an accepted risk with a named, if imperfect, mitigation — the honest posture for a take-home, not a claim of a stronger guarantee than what's actually in place."

20	5. **The repository is public** (`https://github.com/wtvamp/loginid-takehome`), effective 2026-09-12 — updated from a private design-time assumption. This changes the severity, not the substance, of every "never in source or committed config" requirement already in this document and in `handoff-04-secrets.md`: those were always correct discipline; they are now a categorical requirement with no private-repo safety net, since anyone on the internet can read every commit, including history. No secret, real credential, or real PII may ever land in this repository, in any commit, including ones later reverted — a reverted commit is still in git history and still public.
21	6. **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.
22	7. **Trust boundary — deployment operator (dated update, 2026-09-12: first deploy is live).** The deployment target is a **shared production cluster**, reached via a plain nginx Ingress + cert-manager on the cluster's shared LoadBalancer (DNS CNAME to `uplifttech.ddns.net`), public at `https://loginid-takehome.uplifttech.org` — no tunnel involved; 04 deploys with **direct `kubectl`** from a **repo-scoped GitHub Actions Runner Controller (ARC) runner authenticated via a GitHub App**. This is a real deployment, not a hypothetical: the trust boundary named below is now live, not a design-time assumption. 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 the operator (here, effectively the CI pipeline's own deploy identity), 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 CI deploy ServiceAccount itself is now a named instance of this trust boundary** (Tobias Lindqvist's finding): a namespace-scoped Role granting it Secret verbs for app-Secret management would, unless explicitly restricted, also let it read the JWT signing-key Secret — a path from "CI runner compromised" to "mint tokens" that this document did not previously name because there was no live CI deployer to name. Required controls in `handoff-04-secrets.md`: the signing key created out-of-band, and the deployer Role's Secret verbs scoped by `resourceNames` (or a separate namespace) to exclude it. **Because this cluster is shared, not dedicated to this project**, the operator boundary also now includes whoever else has rights on that cluster outside this project's own manifests — a fact worth naming rather than assuming the cluster's blast radius is scoped to this app alone; 04 owns whether that shared-tenancy risk needs any further narrowing (e.g., NetworkPolicy, namespace isolation) beyond what this document already requires.

A Kubernetes volume mount is resolved by the kubelet at pod admission, not gated by RBAC on the referenced Secret held by whoever applied the manifest — so a manifest PR that adds a `volumeMount` for the JWT signing-key Secret directly into the verifying Deployment would be applied successfully by the CI deployer's existing deploy-write access alone, bypassing the Secrets-RBAC lockdown without the pipeline ever calling the Secrets API.

This residual is judged acceptable *for this system* on those three grounds, not treated as solved."
