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.
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.

9:## S1. Scaffolding: Go module, entrypoints, shared bootstrap, config loading (LT-34)
10-
11-**Description:** Stand up the Go module and the two-binary skeleton the org already committed to in `PLANNING.md`'s Service boundaries section: `cmd/api-service`, `cmd/idp-connector`, both thin wrappers over a shared `internal/app` bootstrap package (route registration, config wiring) per `decisions/go-layout-debate.md`. `internal/config` loads the env-var surface named in `PLANNING.md` (`DB_DRIVER`, `DB_DSN`/`DB_DSN_FILE`, `HTTP_ADDR`, `AUTH_JWT_ISSUER`/`AUTH_JWT_AUDIENCE`, `IDP_ABC_*`). Stub handlers only — no DAO, no auth, no connector logic yet; this story's job is a buildable skeleton other stories attach to.
12-
13-**Acceptance criteria:**
14-- [ ] The receiving track (04, reading this for containerization) can act on the resulting layout without re-deriving the reasoning in `PLANNING.md` or `decisions/go-layout-debate.md`.
15-- [ ] Both `cmd/*/main.go` are thin wrappers over `internal/app`; no route-registration or config-loading logic duplicated between them — enforcement site: code review against `decisions/go-layout-debate.md`'s ruling.
16-- [ ] `internal/config` loads every variable named in `PLANNING.md`'s Service boundaries section, with `DB_DSN_FILE` taking precedence over `DB_DSN` when both are set — enforcement site: a config-loading unit test asserting precedence.
17-- [ ] Module builds and both binaries start (against stub handlers) with no real backend configured.

26-## S2. DAO interface, domain types, sentinels, factory (LT-35)
27-
28-**Description:** Implement the interface layer from `05-data-ops/multi-db-strategy.md`'s Go-shaped contract (§1–§4, §3c): the `Repository` composite (`Profiles()`, `Credentials()`, `Methods()`, `CreateProfileWithCredential()`, `DeleteExpired()`, `DeleteProfile()`, `Close()`), the three sub-interfaces, the domain structs (`UserProfile`, `UserCredential`, `AuthMethod`, `ProfileQuery`), the seven sentinel errors, and the `dao.New(driver, dsn)` factory signature. `DeleteExpired`/`DeleteProfile` are defined here as part of the composite skeleton; S11 owns the code that calls them, not their signatures. No backend logic yet — this is the shape both backend packages implement against, plus the fakes S9's tests use per `decisions/test-double-strategy.md`.

  "content": "# LT-34 refinement — S1: walking skeleton (Go module, two binaries, shared bootstrap, config loading)\n\n**Product Owner:** Naomi Voss (01). **Research team:** Imogen Hale, Desmond Okafor, Tobias Lindqvist. **Engineering:** Renata Cole (03). **Source:** `03-engineering-delivery/backlog.md` S1 (LT-34).\n\n## Why this story is pulled first\n\nPer team-lead's recommendation, accepted: this is the walking skeleton — it proves the whole pipeline (build → deploy → publicly reachable) end to end before any feature carries real risk on top of an unproven deploy path. If CI/CD, the two-binary split, or the config surface don't work, every later story inherits that failure; pulling a feature story first would let a deploy-pipeline problem hide behind a feature bug. No objection to the sequencing.\n\n## User-visible outcome (what \"done\" means at the public URL)\n\nBoth binaries are deployed and independently reachable at a public URL, each answering a health probe (`GET /healthz` or equivalent) with:\n- HTTP 200\n- a JSON body containing at minimum: `status: \"ok\"`, `service` (`api-service` or `idp-connector`), and build info (version/commit SHA and build timestamp, however CI injects it)\n\nThis is the one user-visible behavior a walking skeleton has — no other endpoint, no DAO, no auth, no connector logic is expected to do anything yet. \"Done\" is verifiable by any reader with only a browser or `curl` and the URL, without reading any code.\n\n## Acceptance criteria (restated from `backlog.md` S1, plus research-team additions)\n\nFrom `03-engineering-delivery/backlog.md` S1, unchanged:\n- [ ] 04 (reading this for containerization) can act on the resulting layout without re-deriving the reasoning in `PLANNING.md` or `decisions/go-layout-debate.md`.\n- [ ] Both `cmd/*/main.go` are thin wrappers over `internal/app`; no route-registration or config-loading logic duplicated between them. Enforcement site: code review against `decisions/go-layout-debate.md`'s ruling.\n- [ ] `internal/config` loads every variable named in `PLANNING.md`'s Service boundaries section, with `DB_DSN_FILE` taking precedence over `DB_DSN` when both are set. Enforcement site: a config-loading unit test asserting precedence.\n- [ ] Module builds and both binaries start (against stub handlers) with no real backend configured.\n\nAdded for this agile-loop pass, to make the story satisfy the new \"done = deployed and reviewable at a public URL\" bar, which S1 as originally written (a design-phase story) didn't need to state:\n- [ ] Each binary exposes a health endpoint returning 200 + JSON body with `status`, `service`, and build info, per \"User-visible outcome\" above. Enforcement site: an integration test hitting the endpoint in CI, plus the PO review script below run manually against the deployed URL.\n- [ ] CI (GitHub Actions, DevOps-owned) builds both binaries, runs the test suite, and deploys both to a publicly reachable URL on merge to the story's branch/PR environment. Enforcement site: the GitHub Actions workflow run linked from the PR.\n- [ ] The deployed health response's build-info field actually changes between two different commits (proves the deploy is live, not a cached/stale artifact). Enforcement site: PO review script, step 3.\n\n## Non-goals (explicitly out of scope for this story)\n\n- No DAO, no database connection, no `dao.New` implementation — stub handlers only, per the original S1 scope.\n- No auth/authz — the health endpoint is intentionally unauthenticated; it is infrastructure, not part of the API surface 02 designed auth for.\n- No connector logic (`/auth`, `/identity`) beyond the binary existing and starting.\n- No production-grade observability (structured logging, metrics, tracing) — only enough output to confirm the process started; that's `04-infra-devops`'s `observability.md` scope, not this story's.\n- No TLS/custom domain decisions — whatever the CI/CD pipeline's default publicly-reachable URL is (e.g., a platform-provided preview URL) satisfies \"public URL\" for this story; a custom domain is not a goal here.\n\n## PO review script (what I will actually do to accept this story)\n\n1. Open the PR's linked GitHub Actions run; confirm both the build and deploy jobs are green.\n2. `curl -s <public-url-for-api-service>/healthz` and `curl -s <public-url-for-idp-connector>/healthz` (or whatever path engineering names — confirm the actual path from the PR description); confirm both return HTTP 200 and a JSON body with `status`, `service`, and a build-info field.\n3. Confirm the build-info field differs from any previously deployed value I've already checked (or, on the very first deploy, that it's present and non-empty) — this is the one check that proves \"deployed,\" not just \"code exists.\"\n4. Skim the PR diff for `cmd/api-service/main.go` and `cmd/idp-connector/main.go`; confirm each is a thin wrapper (no route registration or config-loading logic inlined) per the acceptance criterion above.\n5. Confirm the config-loading unit test (DSN/DSN_FILE precedence) is present and passing in the CI run.\n\nIf all five pass, the story is accepted and I mark it Done in `backlog.md` (03's file — 04/05's respective backlogs if they also track it) and notify the PM.\n\n## Research team review\n\n**Desmond Okafor — claims check:** [pending]\n\n**Tobias Lindqvist — objection:** [pending]\n\n**Naomi Voss — ruling:** [pending]\n"

26:## S2. DAO interface, domain types, sentinels, factory (LT-35)
27-
28-**Description:** Implement the interface layer from `05-data-ops/multi-db-strategy.md`'s Go-shaped contract (§1–§4, §3c): the `Repository` composite (`Profiles()`, `Credentials()`, `Methods()`, `CreateProfileWithCredential()`, `DeleteExpired()`, `DeleteProfile()`, `Close()`), the three sub-interfaces, the domain structs (`UserProfile`, `UserCredential`, `AuthMethod`, `ProfileQuery`), the seven sentinel errors, and the `dao.New(driver, dsn)` factory signature. `DeleteExpired`/`DeleteProfile` are defined here as part of the composite skeleton; S11 owns the code that calls them, not their signatures. No backend logic yet — this is the shape both backend packages implement against, plus the fakes S9's tests use per `decisions/test-double-strategy.md`.
29-
30-**Acceptance criteria:**
31-- [ ] A hire or reviewer unfamiliar with 05's reasoning can implement a backend against this package without re-reading `multi-db-strategy.md` — the Go types here are the contract, not a paraphrase of it.
32-- [ ] Every sentinel in 05's §4 is defined verbatim (name and wrapped message), including `ErrAlreadyExists`'s status as an internal-error signal with no caller-reachable path — enforcement site: `dao` package source, doc comment on `ErrAlreadyExists` stating that status explicitly (per Oren's finding #1, ruled by 05).
33-- [ ] `CreateProfileWithCredential(ctx, p, c)` exists on the composite per 05's §3b resolution, with `c.UserID` ignored on input — enforcement site: method signature plus a unit test asserting the input `UserID` is overwritten.
34-- [ ] Pointer fields follow "absent, never empty" — a non-nil, empty `*string` is rejected as `ErrInvalidArgument` at the boundary, not silently accepted — enforcement site: input-validation unit test per field.
35-
36-**Depends on:** S1; **05: DAO Go-shaped contract** (`multi-db-strategy.md`, stable, accepted).
37-**Model/effort:** sonnet, high.
38-**Type:** Story.
39-**Labels:** `track-03`, `no-code-yet`.

43-## S3. Postgres/CockroachDB DAO implementation (LT-36)
44-
45-**Description:** The `postgres` package implementing all three `Repository` sub-interfaces for both PostgreSQL and CockroachDB, per `multi-db-strategy.md`'s engine-aware retry-and-error seam requirement (§4). Includes the `crdb.ExecuteTx`-style retry wrapper on every write (CockroachDB stays at SERIALIZABLE per 05's ruling — READ COMMITTED was considered and rejected), SQLSTATE-plus-our-own-constraint-name error translation, and the transactional `CreateProfileWithCredential`.
46-
47-**Acceptance criteria:**
48-- [ ] Implements against S2's interfaces with no re-derivation of 05's schema or error-translation reasoning.
49-- [ ] Every write (`Create`, `Update`, `Upsert`, `Delete`, `CreateProfileWithCredential`) runs through the retry wrapper — enforcement site: the wrapper is the single call path every write method uses, verified by the conformance suite (S5) exercising a retryable condition against CockroachDB.
50-- [ ] Driver errors translate to sentinels by structured code (SQLSTATE) plus our own named DDL constraints, never free-text matching — enforcement site: the translation table in `multi-db-strategy.md` §4, one `switch`/lookup per condition, no `strings.Contains` on an error message anywhere in this package.
51-- [ ] `Upsert`'s `ON CONFLICT DO UPDATE SET` list explicitly excludes `created_at` — enforcement site: the SQL statement itself plus a unit test asserting `created_at` survives a re-hydration Upsert unchanged (per Oren's finding #3, ruled by 05).

  "content": "# LT-35 refinement — S2: DAO interface, domain types, sentinels, factory\n\n**Product Owner:** Naomi Voss (01). **Research team:** Imogen Hale, Desmond Okafor, Tobias Lindqvist. **Engineering:** Renata Cole (03). **Source:** `03-engineering-delivery/backlog.md` S2 (LT-35).\n\n## Why this story is pulled second\n\nLT-34 (walking skeleton) is in implementation. This is the next story in dependency order per `backlog.md` (`Depends on: S1`) and it's the shape every backend implementation (S3 Postgres/CockroachDB, and the SQLite backend) and the test-double fakes (S9) implement against next — it has to land before either backend story can start for real. No feature-priority reason to pull anything else first.\n\n## Acceptance outcome (this story has no public-URL surface — it's an interface, not a running service)\n\nUnlike LT-34, \"done\" here is not something reviewable at a public URL — there's no backend logic yet, nothing to deploy that behaves differently. Acceptance is mechanical and code-level: the interface, types, and sentinels exist, match 05's contract exactly, and CI proves it two ways — (1) the package compiles and its own unit tests (input-validation boundary cases) pass, and (2) a conformance/interface test (Oren's, per `03-engineering-delivery/decisions/test-double-strategy.md`) asserts the Go signatures match `05-data-ops/multi-db-strategy.md` §3 byte-for-byte, not just \"close enough.\"\n\n## Acceptance criteria (restated from `backlog.md` S2)\n\n- [ ] A hire or reviewer unfamiliar with 05's reasoning can implement a backend against this package without re-reading `multi-db-strategy.md` — the Go types here are the contract, not a paraphrase of it.\n- [ ] Every sentinel in 05's §4 is defined verbatim (name and wrapped message), including `ErrAlreadyExists`'s status as an internal-error signal with no caller-reachable path. Enforcement site: `dao` package source, doc comment on `ErrAlreadyExists` stating that status explicitly (per Oren's finding #1, ruled by 05).\n- [ ] `CreateProfileWithCredential(ctx, p, c)` exists on the composite per 05's §3b resolution, with `c.UserID` ignored on input. Enforcement site: method signature plus a unit test asserting the input `UserID` is overwritten.\n- [ ] Pointer fields follow \"absent, never empty\" — a non-nil, empty `*string` is rejected as `ErrInvalidArgument` at the boundary, not silently accepted. Enforcement site: input-validation unit test per field.\n- [ ] (Added for this refinement, the seam-13 mechanical check team-lead named) Every exported type, method signature, and sentinel error name/message in this package matches `05-data-ops/multi-db-strategy.md` §3 **byte-for-byte** — not \"equivalent,\" not \"close enough.\" Enforcement site: a conformance test (Oren's) that fails on any drift, run in CI on the public repo.\n\n## Non-goals\n\n- No backend implementation (Postgres/CockroachDB or SQLite) — that's S3/S4, next in the queue after this.\n- No actual database connection or query execution — `dao.New(driver, dsn)`'s factory signature exists and is callable, but nothing behind it does real I/O yet.\n- No test-double/fake implementation itself — S9 builds the fakes against this interface; this story only has to make that possible, not do it.\n\n## PO review script (what I will actually check to accept this story)\n\nSince there's no public URL for an interface, acceptance is verified entirely in the repo and CI, at `https://github.com/wtvamp/loginid-takehome`:\n\n1. Open the PR; confirm CI is green, specifically Oren's conformance/interface test job (not just \"tests pass\" generally — the specific job that checks signature match against 05's contract).\n2. Diff the PR's `dao` package types/interfaces/sentinels against `05-data-ops/multi-db-strategy.md` §3 myself, spot-checking at least the `Repository` composite, `ProfileQuery`, and the seven sentinel names — I'm not solely trusting the CI job's own claim of a match, since a conformance test can itself have a bug.\n3. Confirm the doc comment on `ErrAlreadyExists` exists and states its internal-error-only status, per the acceptance criterion above (this is the one criterion CI can't easily check — it's a comment, not behavior).\n4. Confirm the \"absent, never empty\" pointer-validation unit tests exist and are named/scoped per-field (not one combined test that could hide a missed field).\n5. Confirm the PR contains no database driver import, no SQL, no connection string handling — this story should touch zero real I/O.\n\nIf all five pass, the story is accepted and I mark it Done in `backlog.md`, then notify the PM.\n\n## Research team review\n\n**Desmond Okafor — claims check:** [pending]\n\n**Tobias Lindqvist — objection:** [pending]\n\n**Naomi Voss — ruling:** [pending]\n"

As written, a test scoped literally to \"§3\" would miss the composite, domain types, and every sentinel — exactly what the acceptance criteria elsewhere require it to check. Fixed by changing every scope reference to §1–§4. Everything else (the `CreateProfileWithCredential`/`c.UserID` criterion, sentinel count and names, `ErrAlreadyExists` status, and the doc-comment-vs-CI distinction I'd asked about) checked out against `multi-db-strategy.md` and 05's own clarifications.\n\n**Tobias Lindqvist — objection:** The conformance test's durability was left implicit — \"byte-for-byte\" reads as a solved, stable check, but a live-doc-parsing implementation and a frozen-copy implementation have opposite failure modes (one breaks CI on unrelated prose edits, the other silently stops meaning anything once 05 revises the contract), and neither is visible in the original PO review script. Counter-proposal accepted: the conformance test must declare its mechanism in a comment, and if frozen-copy, must carry a checksum of the source section and fail loudly on drift rather than passing forever.\n\n**Naomi Voss — ruling:** Both fixes applied. This refinement is accepted and ready to hand off — the §1–§4 scope correction is a real fix (an implementer following the original text would have under-built the conformance test), and the mechanism-declaration/checksum requirement closes a durability gap that wouldn't have surfaced until 05 revised the contract later, by which point it would have been much harder to trace."

7:## Story 1 — Containerize `api-service` and `idp-connector` (LT-45)
8-
9-**Description:** Build the two multi-stage Go images (distroless final stage, non-root, read-only root filesystem) and the Deployment/Service/NetworkPolicy manifests targeting the lab cluster, per `./containerization-design.md`. Covers both binaries' Dockerfiles, resource requests/limits sized per service (CPU-bound `api-service` vs. I/O-bound `idp-connector`), the migration `Job` (parallelism 1, gated by the CI pipeline's exclusivity mechanism, not Kubernetes ordering alone), a default-deny `NetworkPolicy` on `idp-connector` so its "no inbound Service" isolation claim actually holds against the namespace's default-allow network, and — per the consistency pass's F13 finding — a **third manifest**: `api-service-issuer`, a second Deployment of the same `api-service` image (`APP_MODE=issuer`) whose own ServiceAccount is the only one that mounts the JWT signing key, since RBAC on the `Secret` verb does nothing once it's volume-mounted into the verifying Deployment's replicas.
10-
11-**Acceptance criteria:**
12-- [ ] The receiving track (whoever implements/reviews this) can act on the manifests without re-deriving the reasoning in `containerization-design.md`.
13-- [ ] Both images build from a pinned Go version, produce a static binary, and contain nothing but the binary (+ CA certs for `idp-connector`) — enforcement site: multi-stage Dockerfile's final `COPY` list.
14-- [ ] Neither Pod can write to its own root filesystem at runtime — enforcement site: `securityContext.readOnlyRootFilesystem: true`.
15-- [ ] `idp-connector` is unreachable except from `api-service` — enforcement site: the `NetworkPolicy` ingress rule scoped to `api-service`'s pod selector.
16-- [ ] A stuck `idp-connector` cannot starve `api-service` if colocated on one node — enforcement site: `resources.limits` on both Pod specs.
17-- [ ] The migration `Job` cannot start a second concurrent run — enforcement site: the CI pipeline's concurrency-gated deploy stage (Story 3), not a database lock.
18-- [ ] The JWT signing private key is mounted into `api-service-issuer` only, never into `api-service`'s own Deployment — enforcement site: `api-service`'s manifest carries no volume/mount referencing that `Secret` at all, verified by manifest inspection, not RBAC.
19-
20-**Depends on:** 03 — `cmd/api-service` and `cmd/idp-connector` build as real binaries (service boundaries already stable, per `PLANNING.md`); 05 — final migration tooling name for the `Job`'s invocation (already final, `05-data-ops/migration-approach.md`).

47:## Story 3 — CI/CD pipeline: build, lint, test, scan, migrate, describe-only deploy (LT-47)
48-
49-**Description:** Stand up the pipeline in `./ci-pipeline.md`: build/lint/test(`-race`, three DB targets: SQLite, Postgres, CockroachDB)/security-scan/image-build on every PR; push-images/migration-job/describe-only-deploy on merge. The migration-job stage is where 05's R2 exclusivity requirement is actually enforced — a concurrency-gated pipeline stage, not a database lock, since no single lock mechanism covers both the right scope (session, to span `goose`'s per-file transactions) and the right engine (CockroachDB supports transaction-scope only).
50-
51-**Acceptance criteria:**
52-- [ ] A developer or reviewer can act on this pipeline description without re-deriving why each stage exists.
53-- [ ] A lint or test failure blocks merge — enforcement site: required-status-check on the PR, not advisory.
54-- [ ] A CockroachDB-specific SQL incompatibility surfaces at PR time, not deploy time — enforcement site: the dedicated CockroachDB testcontainer job.
55-- [ ] Only one migration run can reach the migrate stage at a time, across concurrent deploys — enforcement site: the pipeline's own concurrency group/mutex on the deploy environment.
56-- [ ] No secret enters a build log or image layer — enforcement site: `gitleaks` stage plus the Dockerfile's minimal `COPY` list (Story 1).
57-- [ ] The final deploy stage is documented (which manifests, which namespace, which credential) but not invoked — enforcement site: stage exists as a named, non-executing step until a separate real-deploy decision is made.

Verified locally: building with `-ldflags` and hitting `/healthz` returns the SHA in the `build` field; building without it falls back to `\"unknown\"` rather than a blank field, so a misconfigured pipeline is visibly wrong. CI (04, `ci-pipeline.md`) should set this flag from the same commit SHA it already tags the Docker image with.\n\nThis PR includes a second, trivial follow-up commit (a comment-only change to `internal/app/buildinfo.go`) per the PO review script's mandatory freshness check — so the deployed `build` field has two distinct values to compare once CI/CD deploys both commits.\n\n## Test plan\n- [x] `go build ./...`, `go vet ./...`, `gofmt -l .` clean\n- [x] `go test ./...` — config precedence tests (`DB_DSN_FILE` over `DB_DSN`, `APP_MODE` default), health-endpoint integration test (status/service/build fields only)\n- [x] Manual smoke test: both binaries built and run locally, `/healthz` hit with curl, build-info confirmed flowing from `-ldflags` into the response\n- [ ] CI build+test job (04, DevOps-owned) — not yet wired, this PR doesn't include workflow files\n- [ ] Deploy to a public URL and PO freshness check (Naomi) — depends on 04's CI/CD pipeline existing\n\n## Non-goals (per refinement/LT-34.md)\nNo DAO, no auth, no connector logic, no production observability, no TLS/domain decisions — stub skeleton only.\n\n🤖 Generated with [Claude Code](https://claude.com/claude-code)","commits":[{"authoredDate":"2026-09-12T23:29:58Z","authors":[{"email":"«email»","id":"MDQ6VXNlcjE0MDM0Nzg=","login":"wtvamp","name":"wtvamp"},{"email":"noreply@anthropic.com","id":"MDQ6VXNlcjgxODQ3","login":"claude","name":"Claude Sonnet 5"}],"committedDate":"2026-09-12T23:29:58Z","messageBody":"…onfig)\n\nImplements S1 per 03-engineering-delivery/backlog.md and\nrefinement/LT-34.md:\n\n- cmd/api-service and cmd/idp-connector are thin wrappers over\n  internal/app, per decisions/go-layout-debate.md's ruling.\n- internal/config loads the env-var surface from PLANNING.md's Service\n  boundaries section; DB_DSN_FILE takes precedence over DB_DSN when both\n  are set (unit-tested).\n- internal/app exposes GET /healthz on both binaries: {\"status\",\"service\",\n  \"build\"} only, per 02's ruling on the unauthenticated health endpoint\n  (api-auth-design.md) — no version string, no timestamp, no connection\n  detail.

85	## 1. The factory and the composite
86	
87	Agreed directly with Renata Cole (03) on 2026-09-12. **Her `dao.New` signature is unchanged**; the composite is the resolution of what had been a silent mismatch between her single `Repository` return type and this track's three interfaces.
88	
89	```go
90	func New(driver, dsn string) (Repository, error)   // driver: "postgres" | "cockroachdb" | "sqlite"
91	
92	type Repository interface {
93	    Profiles()    ProfileRepository
94	    Credentials() CredentialRepository
95	    Methods()     AuthMethodRepository
96	
97	    // CreateProfileWithCredential writes both rows in ONE transaction.
98	    // See §3b.
99	    CreateProfileWithCredential(ctx context.Context, p *UserProfile, c *UserCredential) (*UserProfile, *UserCredential, error)
100	
101	    // Retention and deletion. Both write deletion_log in the SAME transaction
102	    // as the delete. See §3c.
103	    DeleteExpired(ctx context.Context, class RetentionClass, olderThan time.Time, maxRows int) (SweepResult, error)
104	    DeleteProfile(ctx context.Context, id string, externalRef *string) error
105	
106	    Close() error
107	}
108	```
109	
110	`Repository` stays an **interface**, not a struct with exported fields — Renata's reason, which is better than either I offered: an interface is mockable for her test strategy. The three accessors stay distinct rather than flattening into one interface because that separation is a governance control (`pii-governance.md`), not a modelling preference: a call site must reach for the credential accessor deliberately rather than find profile and credential methods side by side on one value.
111	
112	`"postgres"` and `"cockroachdb"` both select the `postgres` package. They are distinct driver strings rather than one because the retry seam in §4 needs to know which engine it is talking to.
113	
114	## 1a. Package placement and how to read these signatures
115	
116	**Added at implementation go, pre-emptively — the acceptance criterion for LT-35 is that signatures match §3 byte-for-byte, and taken literally that criterion cannot be met.** 03's published layout puts the domain structs in `internal/model` and the interfaces in `internal/dao` (`../PLANNING.md` service boundaries). Inside `internal/dao`, a bare `*UserProfile` does not compile; it is `*model.UserProfile`. So the signatures below and the package layout are both right and cannot both be transcribed literally.
117	
118	**Resolution — the signatures in §2–§3 are written unqualified for readability, and the qualified form is the authoritative one:**
119	
120	| Type | Package | Written below as | Authoritative form inside `internal/dao` |
121	|---|---|---|---|
122	| `UserProfile`, `UserCredential`, `AuthMethod` | `internal/model` | `*UserProfile` | `*model.UserProfile` |
123	| `ProfileQuery`, `SweepResult`, `RetentionClass` | `internal/dao` | `ProfileQuery` | `ProfileQuery` — unchanged |
124	| `Repository`, the three repository interfaces | `internal/dao` | as written | unchanged |
125	| Error sentinels (§4) | `internal/dao` | `ErrNotFound` | unchanged |
126	
127	**The placement criterion — dependency direction, not usage.** My first draft justified this by observing that `internal/api` and `internal/connector` both handle the domain structs without touching the DAO. Review replaced that: it is an observation about today's callers, not a criterion, and it would not tell you where to put the next type. It also loses to a competing test — `UserProfile`'s invariants (E.164 phone, upper-case alpha-2 country) are enforced in DDL and on the DAO write path, so an ownership-of-invariants criterion would put `UserProfile` in `dao`, the opposite answer. Two criteria disagreeing is exactly when the stated one has to be the right one.
128	
129	The criterion that holds: **`internal/model` is the leaf — it imports nothing else in `internal/`. A type named by two sibling packages that must not depend on each other belongs in the leaf.** `api` and `connector` both name `UserProfile`; neither may import the other, and neither should have to go through `dao` to say the word. Same conclusion as the usage argument, but checkable, and it decides the next case without a debate.
130	
131	**`ProfileQuery` stays in `dao`, and this is now settled rather than left open.** I had flagged it to 03 as theirs to overrule, on the worry that `api` importing `dao` to construct a query is an interface whose callers must know its implementation package. Review closed it: that objection is about callers knowing `postgres` or `sqlite`, not about knowing `dao`. `api` already imports `dao` to name `dao.Repository` and to compare `dao.ErrNotFound`, so no new dependency edge is created and moving the type would remove nothing. The leaf test agrees — `ProfileQuery` is named across one existing edge and has no meaning without the method that consumes it, so putting it in the leaf would make a package that depends on nothing carry a type defined entirely by something above it. `SweepResult` and `RetentionClass` follow the same reasoning.
132	
133	**New types default to `internal/dao`** unless the leaf test above places them in `model`. The table is a closed list over an open set, which is a drift path in itself — this default closes it, so a type added next month has an answer without reopening this section.
134	
135	**So "matches §3 byte-for-byte" means: same method names, same parameter order, same types modulo the `model.` qualifier in the table above, same return shapes, same error semantics.** A reviewer should read the criterion that way. **Seam 13 against §3 must run with the substitution applied.** §3 is now a deliberately non-literal rendering of the real signatures, so a raw grep-diff would report every domain type as a mismatch — and a mechanical check that reports false positives on its first run gets marked noisy and stops being run, which costs more than never having added it. Applying the table above makes the check exact, and in that form I would take it as LT-35's acceptance gate in preference to a human comparison.
136	
137	This is the first contract ambiguity surfaced by implementation; per the standing rule it is answered by amending this document rather than letting the code decide.
138	
139	*Amended by Priya Nandakumar (05 Data Ops lead); reviewed by Anders Vogel (Systems Cartographer — boundary placement). The ruling was confirmed and two of its three stated reasons were replaced: the usage-based placement argument gave way to the leaf/dependency-direction test, and `ProfileQuery`'s placement was closed with a reason instead of being left to 03 as an overrule. Both drift paths in this section — the non-literal §3 rendering and the closed type table — were found in that review, not by the author.*
140	
141	## 2. Domain types
142	
143	```go
144	type UserProfile struct {
145	    ID            string     // UUID
146	    Name          string     // required, never empty
147	    Phone         *string    // nil if unknown; E.164 when present
148	    StreetAddress *string
149	    Locality      *string
150	    Region        *string
151	    PostalCode    *string
152	    Country       *string    // ISO 3166-1 alpha-2, upper-case
153	    Source        string     // "direct" | "idp_cache"
154	    CreatedAt     time.Time
155	    UpdatedAt     time.Time
156	}
157	
158	type UserCredential struct {
159	    ID          string     // UUID
160	    UserID      string     // FK -> user_profile.id
161	    Username    string     // unique, case-folded
162	    MethodID    string     // FK -> auth_method.id
163	    Secret      []byte     // nil unless SecretState == SecretSet
164	    SecretState string     // "none" | "set" | "revoked"
165	    HashAlgo    *string    // non-nil iff SecretState == "set"
166	    HashCost    *int       // non-nil iff SecretState == "set"
167	    CreatedAt   time.Time
168	    UpdatedAt   time.Time
169	}
170	
171	type AuthMethod struct {
172	    ID             string
173	    Name           string  // "password", "passkey", "otp", "oidc", ...
174	    RequiresSecret bool
175	    IsActive       bool
176	    CreatedAt      time.Time
177	}
178	```
179	
180	**Pointers mean "absent", never "empty".** No field in this contract uses the empty string to mean absent. A `*string` that is non-nil and empty is invalid input, not a value — see §5.
181	
182	**Who owns `ID`, `CreatedAt` and `UpdatedAt`: the DAO, always.**
183	
184	- On `Create`, the caller leaves `ID` as `""`. The DAO generates the UUID (in Go for SQLite, server-side elsewhere) and returns the populated struct. **A non-empty `ID` passed to `Create` is a caller error and returns `ErrInvalidArgument`** — it is not a request to use that ID. This removes the contradiction a cold read found between "callers never see the difference" and `Create` returning `ErrAlreadyExists` "if the ID is taken": for profiles, the ID cannot be taken, because the caller never chooses it.
185	- `CreatedAt` and `UpdatedAt` are set by the DAO on every write and ignored on input. `UpdatedAt` is touched by `Create`, `Update`, and `Upsert` — including IDP re-hydration, which is load-bearing for retention (`pii-governance.md`).
186	
187	**`SecretState` is new and is the fix for a real defect.** The previous prose said `secret` was "nullable, salted hash only" and stopped. Yusuf Karadag's review found that at least three distinct states were collapsing into one null — the method requires no server-held secret (passkey/WebAuthn, where the private key is client-side), the secret is not yet set, or the secret was revoked — and that `auth_method.requires_secret` was consequently load-bearing on nothing. An explicit state column makes the three distinguishable and gives `requires_secret` something to be checked against.
188	
189	## 3. The interfaces
190	
191	```go
192	type ProfileRepository interface {
193	    Get(ctx context.Context, id string) (*UserProfile, error)
194	    Search(ctx context.Context, q ProfileQuery) (results []UserProfile, total int, err error)
195	    Create(ctx context.Context, p *UserProfile) (*UserProfile, error)
196	    Update(ctx context.Context, p *UserProfile) (*UserProfile, error)
197	    Upsert(ctx context.Context, p *UserProfile) (*UserProfile, error)
198	    Delete(ctx context.Context, id string) error
199	}
200	
201	type CredentialRepository interface {
202	    GetByUsername(ctx context.Context, username string) (*UserCredential, error)
203	    ListByUserID(ctx context.Context, userID string) ([]UserCredential, error)
204	    Create(ctx context.Context, c *UserCredential) (*UserCredential, error)
205	    Update(ctx context.Context, c *UserCredential) (*UserCredential, error)
206	    Delete(ctx context.Context, id string) error
207	}
208	
209	type AuthMethodRepository interface {
210	    Get(ctx context.Context, id string) (*AuthMethod, error)
211	    GetByName(ctx context.Context, name string) (*AuthMethod, error)
212	    List(ctx context.Context, activeOnly bool) ([]AuthMethod, error)
213	}
214	
215	type ProfileQuery struct {
216	    Name    *string // case-folded substring match; caller input escaped by the DAO
217	    Phone   *string // EXACT match on the E.164-normalized value (not prefix)
218	    Region  *string // case-folded exact match
219	    Country *string // exact match, alpha-2, upper-cased by the DAO
220	    Limit   int     // 1..100; 0 means "use default 50", deliberately
221	    Offset  int     // 0..10_000
222	}
223	```
224	
225	### `Search` semantics carried over from the S2 ruling
226	
227	These were settled in `decisions/search-query-shape.md` and were missing from the first draft of this contract — the intent-versus-text gap a cold read was run to find.
228	
229	- **`total` is the count of ALL rows matching the filters, ignoring `Limit` and `Offset`** — not the number of rows on this page. Exact, not estimated, computed by a second `COUNT(*)` outside any wrapping transaction, so under concurrent writes it may disagree with the page by a row. **`total` is a magnitude, not a promise of reachability**: it can legitimately exceed what the `Offset` ceiling of 10 000 allows a caller to page to.
230	- **An all-nil `ProfileQuery` is legal** and returns every profile, paginated. `ErrInvalidQuery` covers an *empty* filter (a non-nil pointer to `""`), not the *absence* of filters. Whether a given caller may list all profiles is authorization policy owned by `../02-ai-security-architecture/`; the DAO does not invent one, and the pagination ceiling is protection rather than a policy veto.
231	- **Filters combine with AND.** No OR, no negation.
232	- **Searching for *absent* address values is out of scope.** `nil` means "don't filter" and `""` is an error, so no legal query reaches rows with a NULL `region`. Callers needing that list and filter client-side. This matters because partial addresses from `/identity` are the normal case for `idp_cache` rows.
233	
234	### What `Search` does on SQLite — read this before assuming parity
235	
236	The first draft said nothing about this anywhere; the only trace was "Postgres + CockroachDB only" in the index table, which a reader cannot turn into behaviour.
237	
238	SQLite runs **the same query with the same results in the same order** — `LOWER(name) LIKE ?` with explicit case folding and `COLLATE BINARY` ordering — but **without any index to accelerate it**, so it is a full table scan. Row sets and ordering are identical to Postgres for ASCII input; only speed differs. That identity is not an accident of the query text, it is asserted by the conformance suite in §7, which is the only thing that keeps it true as the code changes.
239	
240	The one residual difference, accepted and named: Postgres `lower()` is locale-aware and SQLite's is ASCII-only, so **non-ASCII** case folding still diverges between backends. SQLite is the local/dev/demo backend, not a production peer.
241	
242	`CredentialRepository` never accepts or returns a `UserProfile` field, in either direction, including as an internal convenience struct. That is §6.1.
243	
244	**`Create` / `Update` / `Upsert` are three distinct methods, and this changes the earlier prose.** The previous version of this document described `Update` as "implemented as a portable upsert", which would mean `Update` on a missing row silently *creates* it. That is exactly the kind of surprise that produces a bug in a caller, so it is ruled out:

{
  "file_path": "/Users/warrenthompson/Source/LoginID/05-data-ops/multi-db-strategy.md",
  "offset": 262,
  "limit": 90
}

262	## 3b. The one cross-table operation: atomic registration
263	
264	Added after 03's Detail Hawk review found a gap that was not yet a contradiction but would have become one. The contract bars 03 from composing its own multi-statement transaction across calls (§3), and contained no method writing more than one table — so the assignment's registration flow (create a profile, create its first credential) had **no atomic path at all**. Two independent calls leave a window in which a profile exists with PII and no credential; if the second call fails, that window never closes.
265	
266	That orphan is the same failure class as the orphaned IDP cache row in `pii-governance.md`: a PII-bearing row nothing references, governed by a retention clock written for a different case. Discovering it during implementation would have meant either an orphan-producing registration flow or 03 improvising the transaction the contract forbids.
267	
268	**Ruling: the DAO supplies the transaction, because the DAO is the only layer allowed to open one.**
269	
270	- It lives on the **composite**, not on either sub-repository — it spans both tables, and putting it on `CredentialRepository` would breach §6.1 (that interface still never accepts or returns a `UserProfile`; the composite is a different type and the separation is intact).
271	- Both rows are written in one transaction, and on CockroachDB the whole transaction runs inside the retry seam (§4).
272	- IDs are DAO-generated for both, as everywhere else. `c.UserID` is ignored on input and set from the profile the DAO just created — a caller cannot supply a mismatched pair.
273	- Errors: any of `Credentials().Create`'s errors, plus `ErrInvalidArgument`. On any failure **neither row exists**.
274	- This is the *only* cross-table operation in the contract, and it stays that way. A second one is a change to this contract, not an implementation decision.
275	
276	## 3c. Retention and deletion — added after the consistency pass (F21)
277	
278	`pii-governance.md` specifies a bulk retention sweep and a subject-deletion request sharing **the same code path**, each writing a `deletion_log` row, and §5 of this contract defines that table. **None of it was reachable from the interface.** There was no sweep method, no log method, `Profiles().Delete` wrote no log row, and §3 forbids 03 from opening a transaction to combine the two — so a policy this track ruled on could not be implemented against the contract this track wrote, and no track owned the gap. Found by the cross-track consistency pass, not by any of this track's four reviewers, because every one of them was scoped to a single document and the contradiction lived between two.
279	
280	Both methods sit on the **composite**, for the same reason as `CreateProfileWithCredential`: they span `user_profile` and `deletion_log`, and the DAO is the only layer permitted to open a transaction.
281	
282	```go
283	type RetentionClass string // "direct" | "idp_cache" | "idp_cache_orphan"
284	
285	type SweepResult struct {
286	    RowsExamined      int
287	    RowsDeleted       int
288	    OldestSurvivingAt *time.Time // see "what nil means" below — NOT "nothing was old enough"
289	    Drained           bool       // true when this class had no more deletable rows at the batch limit
290	}
291	```
292	
293	**What `OldestSurvivingAt` means, stated precisely because three conditions were collapsing into one nil.** It is the clock-column value of **the oldest row remaining in this class after this call** — every remaining row, not only rows that were candidates for deletion. It is `nil` **only when the class has zero rows remaining**, and never for any other reason. In particular it is *not* nil when nothing was old enough to delete: survivors exist, and their oldest age is exactly the number the health check wants (it will simply be younger than the window, which is the healthy case). Without this, "sweep is working and the data is young" and "sweep has stopped and I cannot tell" both returned nil, which would have defeated the field's only purpose.
294	
295	**`OldestSurvivingAt` is meaningful only when `Drained` is true.** This falls out of batching and neither review raised it on its own: mid-sweep, deletable rows remain by construction, so the oldest survivor is old and the metric would fire spuriously on every batch but the last. 04 alerts on `OldestSurvivingAt` **only from a `Drained` result**; a non-drained batch reports progress, not health.
296	
297	**`DeleteExpired(ctx, class, olderThan, maxRows)`** — one class per call, never a mixed-class predicate, because a single predicate spanning two clocks is how the wrong window gets applied to the wrong rows.
298	
299	**Bounded by `maxRows`, and one transaction per batch — not one per sweep.** A class-wide delete with no chunking holds a single transaction over an unbounded row count, which is the failure mode 03 already identified for credential writes in their `context-propagation.md`. `maxRows` is required, must be in `1..10_000`, and returns `ErrInvalidArgument` outside it. The caller loops until `Drained` is true. Each batch is its own transaction, so an interrupted sweep leaves a consistent database with fewer rows deleted — never a half-written batch.
300	
301	**`DeleteExpired` must not be called with a request-scoped context.** It is a background operation governed by the job's own timeout; a sweep cancelled halfway because an inbound HTTP request went away is a retention policy that silently depends on request lifetimes. Constructing that context is 03's layer, not the DAO's — stated here as a requirement on the caller, with its enforcement site named as 03's sweep-invocation code plus a conformance test asserting an already-cancelled context returns before deleting anything. The clock column is the class's own: `updated_at` for `direct` and `idp_cache`, **`created_at` for `idp_cache_orphan`** — a clock the read path touches would let an orphan reset its own expiry and never die. Each deleted profile cascades to its credentials and writes one `deletion_log` row with reason `retention_sweep`, in the same transaction as the delete.
302	
303	`SweepResult` returns the three metrics `pii-governance.md` requires, and **`OldestSurvivingAt` is the load-bearing one**: it is the only signal that detects a silently stopped sweep, because rows-deleted cannot distinguish a broken sweep from a legitimately empty one — both report zero. Returning it from the DAO rather than leaving 04 to compute it is deliberate: the DAO is the only layer that can answer it in the same query plan as the sweep.
304	
305	**`DeleteProfile(ctx, id, externalRef)`** — subject-deletion. Writes the `deletion_log` row in the same transaction, with **`reason` set internally to `subject_request`; it is not a parameter.**
306	
307	That is a deliberate narrowing from the first draft, which took `reason` as a caller-supplied string. A free string lets a caller write `retention_sweep` onto a subject-deletion row by copy-paste, which silently destroys the one property the audit trail exists to have: that its reason codes are trustworthy. **The reason a row exists is a fact about which method was called, so the method should assert it — not the caller.** `DeleteExpired` writes `retention_sweep` the same way. The two reason codes in `ck_deletion_log_reason` are therefore exhaustive by construction rather than by convention, and a third value is a contract change that adds a method, not a new string a caller may pass.
308	
309	**This supersedes `Profiles().Delete` for anything governed by retention.** `Profiles().Delete(ctx, id)` remains for ordinary application deletes and still writes **no** log row — deliberate, because a log of every incidental delete is not an audit trail, it is noise with PII-adjacent identifiers in it. If that distinction proves wrong in implementation, flag it rather than making `Delete` log.
310	
311	**Neither method is a "third cross-table operation" loophole.** These two plus `CreateProfileWithCredential` are the complete set; a fourth is a change to this contract.
312	
313	## 3a. Per-method summary — read this row before writing that method
314	
315	Added after a cold read observed that this document is organized by *artifact* (factory, types, interfaces, errors, schema) while an implementer works by *verb* — so answering "I am about to write `Create`, what do I need?" meant holding five sections open at once. Four of that read's fourteen blocking questions existed only because a method's full story was never assembled in one place. This table closes them by construction; the prose above remains the authority where they disagree.
316	
317	| Method | Caller supplies `ID`? | Timestamps | Replace or patch | Can return |
318	|---|---|---|---|---|
319	| `Profiles().Get` | yes (lookup key) | — | — | `ErrNotFound` |
320	| `Profiles().Search` | — | — | — | `ErrInvalidQuery` |
321	| `Profiles().Create` | **no** — must be `""`, DAO generates | DAO sets both | — | `ErrInvalidArgument` (non-empty ID, or CHECK violation); `ErrAlreadyExists` — see note below |
322	| `Profiles().Update` | yes — identifies the row | DAO sets `UpdatedAt` | **full replace**; nil NULLs the column | `ErrNotFound`, `ErrInvalidArgument` |
323	| `Profiles().Upsert` | **yes** — conflict target; caller must already hold it | DAO sets `UpdatedAt`; sets `CreatedAt` on insert only — **the `DO UPDATE SET` list must exclude `created_at`** | **full replace** | `ErrInvalidArgument` |
324	| `Profiles().Delete` | yes | — | — | `ErrNotFound`; **cascades to credentials, see §6.2** |
325	| `Credentials().GetByUsername` | — | — | — | `ErrNotFound`; DAO lower-cases input |
326	| `Credentials().ListByUserID` | — | — | — | empty slice, not `ErrNotFound`, when the user has none |
327	| `Credentials().Create` | **no** — DAO generates | DAO sets both | — | `ErrDuplicateUsername`, `ErrInvalidMethod`, `ErrInvalidCredential`, `ErrInvalidArgument` |
328	| `Credentials().Update` | yes | DAO sets `UpdatedAt` | **full replace** | `ErrNotFound`, `ErrDuplicateUsername`, `ErrInvalidCredential` |
329	| `Credentials().Delete` | yes | — | — | `ErrNotFound`; does **not** delete the profile (§6.2) |
330	| `Methods().Get` / `GetByName` | yes / name | — | — | `ErrNotFound` |
331	| `Methods().List` | — | — | — | empty slice when none |
332	
333	`DeleteExpired` and `DeleteProfile` (§3c) are not in the table above: both are composite-level, both write `deletion_log` in the same transaction as the delete with the reason code asserted by the method rather than the caller, `DeleteExpired` returns counts rather than rows and is batched by a required `maxRows`, and both return `ErrInvalidArgument` on a bad class or batch bound. `CreateProfileWithCredential` (§3b) is likewise not in it because it spans two rows: IDs DAO-generated for both, `c.UserID` ignored on input and set from the created profile, both timestamps DAO-set, and on failure neither row exists.
334	
335	Every write method above additionally runs inside the retry seam described in §4 when the engine is CockroachDB.
336	
337	**Three clarifications from 03's first-pass review, each resolving an ambiguity rather than changing a decision:**
338	
339	1. **`ErrAlreadyExists` is real but not caller-reachable.** Because no caller supplies an ID, a primary-key collision can only arise from a UUID collision or a duplicated retry — never from caller error. It stays in the sentinel set and stays translated (it is one branch in the error mapping), but it is documented as an **internal-error signal, not a caller contract**, and the conformance suite is **not** required to exercise it. 03 should not spend effort constructing a test for a path a caller cannot reach.
340	
341	2. **`Limit == 0` means "default 50", and requesting zero rows is out of scope.** The review correctly noted this is the same zero-value trap the pointer-means-absent convention avoids elsewhere in the struct. Accepted as a deliberate exception rather than fixed: a count-without-rows query is a *different operation*, and if it is ever wanted it arrives as an explicit `Count(ctx, ProfileQuery)` method — not as a magic value of `Limit`. `total` already gives a caller the count alongside the smallest useful page.
342	
343	3. **`Upsert` must not overwrite `created_at`.** Its `ON CONFLICT (id) DO UPDATE SET` list excludes `created_at` explicitly. Without that, every IDP re-hydration would silently reset the creation timestamp — on a column `pii-governance.md` keys retention to. This was an omission that would have produced a silent, retention-affecting bug, and it is now stated at both the method table and here.

// composite, domain types, sub-interfaces plus ProfileQuery, and sentinels)
// byte-for-byte, not "close enough".
//
// MECHANISM: FROZEN COPY, not live-parse. Reliably extracting exact Go
// signatures out of markdown prose is impractical — multi-db-strategy.md is
// prose describing Go shapes inside fenced code blocks, not a Go source
// file a parser can trust. Instead, the "expected*" declarations below were
// transcribed by hand from §1–§4 at the time this test was written, and
// pinned two independent ways so a drift on either side is caught:
//
//  1. Structural, on OUR side: assertInterfaceEquivalent checks the actual
//     dao interfaces against the hand-transcribed expected* interfaces by
//     mutual reflect.Type.AssignableTo (same method set, both directions)
//     plus a method-count check, which catches an added, removed, or
//     resignatured method that "compiles fine" checks alone would miss.
//     assertStructFields does the same for domain/query/result structs,
//     field by field, in order. The factory signature (§1) is pinned by a
//     compile-time function-variable assignment — a mismatch fails the
//     build, not just this test. Sentinel identity (§4) is checked by
//     exact wrapped-message string equality, and sentinel-SET completeness
//     (nothing added or removed without updating this test) is checked by
//     parsing this package's own errors.go with go/parser — a syntax parse
//     of our own Go source, not of the markdown, so it doesn't fall under
//     the "impractical" case above.
//
//  2. Drift, on the DOC's side: TestContractChecksumUpToDate hashes
//     05-data-ops/multi-db-strategy.md's §1–§4 section (delimited by the
//     marker strings below, matching this file's own scope) and compares
//     it against expectedContractChecksum, frozen at transcription time.
//     If 05 revises that section, this test FAILS LOUDLY instead of
//     silently continuing to assert a stale copy of the contract — a human
//     must re-transcribe the expected* declarations below and refresh the
//     checksum constant, not just bump a version number.
//
// Known scope limit, stated rather than hidden: this test proves the Go
// shapes named in §1–§4 match what was transcribed from the doc at the time
// of transcription, and that the doc section hasn't since changed
// underneath that transcription. It cannot prove the original transcription
// itself was faithful — that's why the PO review script
// (refinement/LT-35.md) has a human diff the PR against the doc directly,
// rather than trusting this test's own claim of a match.

43:## S3. Postgres/CockroachDB DAO implementation (LT-36)
44-
45-**Description:** The `postgres` package implementing all three `Repository` sub-interfaces for both PostgreSQL and CockroachDB, per `multi-db-strategy.md`'s engine-aware retry-and-error seam requirement (§4). Includes the `crdb.ExecuteTx`-style retry wrapper on every write (CockroachDB stays at SERIALIZABLE per 05's ruling — READ COMMITTED was considered and rejected), SQLSTATE-plus-our-own-constraint-name error translation, and the transactional `CreateProfileWithCredential`.
46-
47-**Acceptance criteria:**
48-- [ ] Implements against S2's interfaces with no re-derivation of 05's schema or error-translation reasoning.
49-- [ ] Every write (`Create`, `Update`, `Upsert`, `Delete`, `CreateProfileWithCredential`) runs through the retry wrapper — enforcement site: the wrapper is the single call path every write method uses, verified by the conformance suite (S5) exercising a retryable condition against CockroachDB.
50-- [ ] Driver errors translate to sentinels by structured code (SQLSTATE) plus our own named DDL constraints, never free-text matching — enforcement site: the translation table in `multi-db-strategy.md` §4, one `switch`/lookup per condition, no `strings.Contains` on an error message anywhere in this package.
51-- [ ] `Upsert`'s `ON CONFLICT DO UPDATE SET` list explicitly excludes `created_at` — enforcement site: the SQL statement itself plus a unit test asserting `created_at` survives a re-hydration Upsert unchanged (per Oren's finding #3, ruled by 05).
52-- [ ] Fuzzy name search uses the `LOWER(name) LIKE ?` form matching the GIN expression index, with explicit `%`/`_`/`\` escaping — enforcement site: query construction plus a unit test with a `%`-containing search term.
53-
54-**Depends on:** S2.

61:## S4. SQLite DAO implementation (LT-37)
62-
63-**Description:** The `sqlite` package implementing all three `Repository` sub-interfaces, per `multi-db-strategy.md`'s dialect-difference table: app-side UUID generation before insert, `LIKE`-based fuzzy search with explicit case folding to match Postgres row sets for ASCII input, extended-result-code error translation (`SQLITE_CONSTRAINT_*`) disambiguated by the same DDL constraint names as the Postgres package.
64-
65-**Acceptance criteria:**
66-- [ ] Implements against S2's interfaces with no re-derivation of 05's schema or dialect reasoning.
67-- [ ] `Create` generates the UUID in Go (SQLite has no server-side generation) before insert — enforcement site: the `Create` implementation, verified by the conformance suite asserting a populated `ID` comes back identically to the Postgres path.
68-- [ ] Search folds case explicitly (`LOWER(col) LIKE LOWER(pattern)`) rather than relying on SQLite's default ASCII case-insensitivity, so behavior is asserted rather than incidental — enforcement site: the query construction plus the conformance suite's cross-backend result-set comparison.
69-- [ ] `SQLITE_CONSTRAINT_UNIQUE`/`FOREIGNKEY`/`CHECK`/`PRIMARYKEY` map to the same sentinels as the Postgres package's SQLSTATE codes, disambiguated by the same constraint names — enforcement site: the translation table, verified by the conformance suite's sentinel-parity assertion.

78-## S5. Conformance suite (05's requirement, cross-backend) (LT-38)
79-
80-**Description:** One suite, written once against the `Repository` interfaces, run against every backend implementation (postgres, cockroachdb, sqlite) — not per-package unit tests, per `multi-db-strategy.md` §7 and `decisions/multi-db-abstraction.md`. This is the enforcement site for every guarantee in 05's contract that can't be a DDL constraint: identical `Search` result sets/ordering across backends (closing the documented SQLite `LIKE` case-sensitivity correctness gap, not a performance one), sentinel parity via `errors.Is` for every condition in §4, the secret-state rules (§5/§6.11), `is_active` enforcement (§6.10), and empty-string rejection on every `*string` filter.

### The write-path retry seam — a decision, not an observation

CockroachDB defaults to SERIALIZABLE and returns client-retryable `40001` in situations PostgreSQL at READ COMMITTED never produces, and its internal retry cannot help once results have begun streaming. `Upsert`'s `ON CONFLICT DO UPDATE` under contention is directly exposed to this.

**Ruling: every write goes through a `crdb.ExecuteTx`-style retry wrapper, and the CockroachDB backend stays at its default SERIALIZABLE.** The alternative — running CockroachDB at READ COMMITTED to drop the requirement — was considered and rejected: CockroachDB's READ COMMITTED is documented as *stronger* than PostgreSQL's, so choosing it to "simplify" would introduce a second engine-behaviour divergence hiding behind a matching level name. That is the same error, one layer down, that this phase has spent its time removing. The wrapper is near-zero cost on PostgreSQL and load-bearing on CockroachDB.

`Search` is read-only, two independent statements, no explicit transaction — it never encounters `40001` and needs no wrapper.

**Where the wrapper sits, and how it knows the engine.** The ruling above said *that* writes retry and not *where* the retry lives — a cold read pointed out that three implementers would produce three different codebases from it, all faithful. Settled:

- The wrapper is an **unexported helper inside the `postgres` package**, e.g. `withRetry(ctx, func(tx) error)`, and every write method in that package runs its statement inside it. It is not in the composite from §1 and not above the interface: putting it there would wrap reads too and would push engine-specific behaviour above the boundary the interface exists to draw.
- The **`sqlite` package has no wrapper at all** — not a no-op shim. SQLite has no retryable-serialization error class, so a no-op would be ceremony implying a shared abstraction that does not exist.
- The `postgres` implementation struct carries an unexported `engine` field set by `New` from the driver string — `"postgres"` or `"cockroachdb"`. `withRetry` retries only when `engine == cockroachdb`; on `"postgres"` it calls the function once and returns. **That field is the entire reason the two driver strings are distinct** despite selecting the same package, which §1 asserted without saying how the distinction was carried.

## 5. Field-level schema

{
  "file_path": "/Users/warrenthompson/Source/LoginID/03-engineering-delivery/decisions/error-semantics.md"
}

1	# Decision: Error semantics (wrap vs. sentinel)
2	
3	Pattern: rotating devil's advocate, decision 1 of 3 (seat: Oren Castellan). Proposer: Renata Cole.
4	
5	## Proposal
6	
7	Go 1.13+ error wrapping (`fmt.Errorf("...: %w", err)`) for propagating unexpected/lower-level errors up the call stack, plus a small set of exported sentinel errors (`dao.ErrNotFound`, `dao.ErrDuplicate`) for conditions callers are expected to branch on via `errors.Is`.
8	
9	## Objections — Oren Castellan (Detail Hawk)
10	
11	1. **Sentinel set must be closed and enumerated now**, not left open-ended — otherwise hires add ad hoc `ErrX` values across S2–S4 with no stable contract. Wants a fixed list plus a named owner and a propose-before-adding rule.
12	2. **Wrapped errors must never cross the HTTP boundary raw** — `err.Error()` on a wrapped DB error can leak driver text (DSN fragments, column/constraint names) to an API client. Wants an explicit translation function at the boundary; anything unmapped defaults to a generic 500 with no wrapped detail.
13	3. **`errors.Is` against a sentinel breaks silently if a backend returns a driver-native error instead** (e.g. `*pgconn.PgError` instead of `dao.ErrDuplicate`). Wants the `Repository` interface contract to state translation is *mandatory* per backend, verified by an S5 test case per backend.
14	4. **No stated rule for `context.DeadlineExceeded`/`context.Canceled`.** These aren't ordinary internal errors and shouldn't page as generic 500s. Wants them checked and mapped to a distinct response code before generic wrapping applies.
15	
16	## Ruling (Renata Cole)
17	
18	All four accepted; no decline.
19	
20	1. Sentinel set is closed and fixed now: `dao.ErrNotFound`, `dao.ErrDuplicate`, `dao.ErrInvalidInput`. Defined once in `internal/dao`. Rule: no hire adds a sentinel unilaterally — propose it to me with the one-line reason, I add it. This applies for the rest of the design/implementation phase.
21	2. `internal/api` never serializes `err.Error()` on an unmapped error. A translation function (`internal/api` boundary layer) maps the three sentinels to their HTTP status/safe message; anything else defaults to a generic 500 with no wrapped detail surfaced to the client. Wrapped errors are for logs only.
22	3. The `Repository` interface contract states translation of known driver-native errors to the shared sentinels is **mandatory**, not optional, per backend implementation. S5's test strategy gets an explicit line item: one test per backend proving the translation happens (e.g., a unique-constraint violation surfaces as `dao.ErrDuplicate`, not a raw driver type).
23	4. `context.DeadlineExceeded` and `context.Canceled` are checked explicitly and mapped to a distinct response (504 for deadline exceeded; treat client-cancel as a non-alerting outcome, not logged as a 500) before generic wrapping/translation applies.
24	
25	## Status
26	
27	Ruled. Carries into S2 (DAO sentinel definitions + per-backend translation) and S3 (handler-layer translation function, context-error handling).
28	
29	## Superseded in part — 05's contract lands (2026-09-12)
30	
31	05's `multi-db-strategy.md` §4 is the authoritative sentinel set and translation mechanism for the DAO layer; it supersedes the specific names and the translation rule this decision guessed at before the contract existed. What stands vs. what's replaced:
32	
33	- **Replaced:** the invented sentinel set (`ErrNotFound`/`ErrDuplicate`/`ErrInvalidInput`) is superseded by 05's actual seven: `ErrNotFound`, `ErrAlreadyExists`, `ErrDuplicateUsername`, `ErrInvalidMethod`, `ErrInvalidQuery`, `ErrInvalidArgument`, `ErrInvalidCredential`. These are 05's to own and extend (own-and-propose-before-adding now routes through them, not me, for anything DAO-internal) — my closed-set/no-ad-hoc-additions principle still applies, just to their list.
34	- **Replaced:** "match SQLSTATE only" is superseded by 05's corrected rule — match structured error codes (SQLSTATE on Postgres/CockroachDB, extended result codes on SQLite) plus constraint names we define ourselves in DDL, never free-text messages. This is a more complete version of objection 2's concern (leaking driver text), not a contradiction of it.
35	- **Stands unchanged:** the HTTP-boundary rule (objection 2 — `internal/api` never serializes `err.Error()` on an unmapped error; wrapped errors are for logs only) — this is 03's layer, not 05's, and 05's contract doesn't touch it. The context-cancellation rule (objection 4) also stands unchanged, same reason.
36	- **Stands, now backed by a real mechanism instead of a guess:** objection 3's demand for mandatory per-backend translation — 05's contract §4 gives the actual mapping table (condition → PG/CRDB code → SQLite code → sentinel), and §7's conformance suite makes "sentinel parity for every error condition in §4" a stated, required test — stronger than what this decision asked for.
37	
38	## Consistency-pass fixes (2026-09-12)
39	
40	**F7 — authn/authz failure mapping was unstated.** This decision covered DAO-sentinel and context-error mapping but never said what an authn failure (missing/invalid token) or an authz failure (scope check, or an `authorize()` policy denial) returns. Fixed: a missing or invalid token → `401`. A scope failure and an `authorize()` policy denial both → `403`, with an **identical client-visible response body** — the two are distinguished only in the audit log (`handoff-03-auth.md`'s "policy decision: allow/deny, and if deny, whether it was a scope failure or an authorize() denial" field), never in what the client sees. This closes the gap the consistency pass found in `handoff-03-auth.md:27,50`'s "distinct signals for detection" requirement.
41	
42	**F50 — the boundary-sanitization rule needed to name driver `DETAIL` text explicitly.** The translation function (ruling item 2, above) already stated that unmapped errors default to a generic 500 with no wrapped detail — but a Postgres CHECK or unique-violation error's `DETAIL` line (which echoes the failing row's actual column values, including PII) is exactly the kind of "wrapped detail" that rule exists to stop, and it wasn't named specifically enough for a reader to be sure it was covered. Stated explicitly now: **the translation layer sanitizes every driver error down to its structured code plus our own constraint name before wrapping it for the log — the raw driver error (including any `DETAIL`/`Key (...)=(...)` text) is never wrapped, logged, or passed through in any form.** This translation layer (05's §4 mapping, implemented in `internal/dao`) is the enforcement site; `handoff-04-secrets.md`'s never-log list gets the matching entry from 02.

  "content": "# LT-36 / LT-37 refinement — S3/S4: backend DAO implementations (Postgres+CockroachDB, SQLite)\n\n**Product Owner:** Naomi Voss (01). **Research team:** Imogen Hale, Desmond Okafor, Tobias Lindqvist. **Engineering:** Renata Cole (03), running both in parallel worktrees. **Source:** `03-engineering-delivery/backlog.md` S3 (LT-36) and S4 (LT-37).\n\n**Who did the work:** Refined by Naomi Voss (PO); claims check Desmond Okafor; objection Tobias Lindqvist; engineering counterpart Renata Cole.\n\n## Why pulled together, as a pair\n\nBoth depend only on LT-35 (merged), neither depends on the other, and Renata's running them in parallel worktrees — refining them together avoids two near-identical refinement passes and lets the shared acceptance criteria (conformance suite, sentinel translation) be stated once instead of twice, with only the genuinely backend-specific pieces (retry seam for CockroachDB; case-folding and app-side UUIDs for SQLite) kept separate.\n\n## Acceptance outcome (both stories — no public-URL surface, same as LT-35)\n\nNeither story has user-visible behavior yet — no handlers call these packages. Acceptance is mechanical: the conformance suite (LT-38, not yet pulled, but its assertions are what \"done\" means here even before it exists as its own story) run against each backend passes, sentinel translation is verified per-condition per-backend, and the CockroachDB-specific retry seam and SQLite-specific parity gaps are each proven, not just implemented.\n\n## Shared acceptance criteria (both LT-36 and LT-37)\n\n- [ ] Implements against LT-35's interfaces with no re-derivation of 05's schema, error-translation, or dialect reasoning — restated from `backlog.md`.\n- [ ] Driver errors translate to the seven sentinels (`multi-db-strategy.md` §4) by structured code (SQLSTATE for Postgres/CockroachDB, extended result code for SQLite) plus our own named DDL constraints — **never free-text/`strings.Contains` matching on an error message**, per `decisions/error-semantics.md`'s superseded-but-standing rule and 05's §4. Enforcement site: the translation table/switch in each backend package; a grep for `strings.Contains` against any error string returns nothing in either package.\n- [ ] Sentinel translation is proven per-condition, per-backend — not asserted by code review alone. Enforcement site: the conformance suite (LT-38) exercises every §4 condition against both backends and asserts `errors.Is` against the correct sentinel, per `decisions/error-semantics.md`'s \"mandatory per-backend translation, verified by an explicit test case per backend.\"\n- [ ] No raw driver error text (including a Postgres `DETAIL`/`Key (...)=(...)` line or a SQLite extended-code message) is ever wrapped, logged, or returned past the translation boundary — per `decisions/error-semantics.md` F50. Enforcement site: the translation function sanitizes to structured code + our constraint name before anything is wrapped for the log; a test asserting a constraint-violation error's logged/wrapped form contains no literal column value.\n- [ ] `Upsert`'s `ON CONFLICT`/`ON CONFLICT DO UPDATE` (or SQLite equivalent) explicitly excludes `created_at` from the update-set list — per 05's Oren-finding-#3 ruling. Enforcement site: the SQL/query statement itself, plus a unit test asserting `created_at` survives a re-hydration `Upsert` unchanged, one test per backend (not one test assumed to cover both).\n- [ ] `CreateProfileWithCredential` writes both rows in one transaction with `c.UserID` ignored on input and set from the newly created profile; on any failure, neither row exists. Enforcement site: a unit test per backend that fails the credential write deliberately (e.g. a duplicate username) and asserts the profile row does not exist afterward.\n\n## LT-36-specific acceptance criteria (Postgres + CockroachDB)\n\n- [ ] Every write method (`Create`, `Update`, `Upsert`, `Delete`, `CreateProfileWithCredential`) runs through the `withRetry` wrapper described in `decisions/error-semantics.md` — an unexported helper inside the `postgres` package, not in the composite and not above the interface boundary. Enforcement site: the wrapper is the single call path every write method uses; grep confirms no write method executes a statement outside it.\n- [ ] The wrapper retries only when the implementation's unexported `engine` field (set by `New` from the driver string) is `\"cockroachdb\"`; on `\"postgres\"` it calls the function once. Enforcement site: a unit test constructing both engine values and asserting call count under a forced-retryable and a non-retryable condition.\n- [ ] The retry wrapper actually retries a genuine SQLSTATE `40001` (serialization failure) against real CockroachDB, not a mocked/simulated one. Enforcement site: the conformance suite (LT-38) exercises a real retryable condition against a CockroachDB testcontainer/instance, per `backlog.md`'s own acceptance criterion for this story.\n- [ ] `Search` opens no explicit transaction and is not wrapped by `withRetry` — it's read-only and per `decisions/error-semantics.md`'s ruling never encounters `40001`. Enforcement site: code review confirming `Search`'s implementation has no `withRetry` call.\n- [ ] Fuzzy name search uses `LOWER(name) LIKE ?` matching the GIN expression index, with explicit `%`/`_`/`\\` escaping on caller input. Enforcement site: query construction plus a unit test with a search term containing a literal `%` or `_`, asserting it's treated as a literal character, not a wildcard.\n\n## LT-37-specific acceptance criteria (SQLite)\n\n- [ ] `Create` generates the UUID in Go before insert (SQLite has no server-side generation) — enforcement site: the `Create` implementation, verified by the conformance suite asserting a populated `ID` comes back structurally identical to the Postgres path (same format, non-empty, DAO-generated either way).\n- [ ] Search folds case **explicitly** — `LOWER(col) LIKE LOWER(pattern)` — rather than relying on SQLite's default ASCII case-insensitive `LIKE`, so the behavior is asserted by this package's own code, not an accident of the engine default. Enforcement site: the query construction plus the conformance suite's cross-backend result-set comparison (same rows, same order, for ASCII input, per `multi-db-strategy.md`'s \"What Search does on SQLite\" section).\n- [ ] The documented non-ASCII case-folding divergence (Postgres `lower()` is locale-aware, SQLite's is ASCII-only) is **not silently accepted as an untested gap** — it must appear as an explicit, named exception in this package's own documentation (a doc comment on the search implementation), not only in `multi-db-strategy.md`'s prose, so a reader of the code alone sees the limitation. Enforcement site: doc comment in the SQLite search implementation, cross-referenced to `multi-db-strategy.md`.\n- [ ] `SQLITE_CONSTRAINT_UNIQUE`/`FOREIGNKEY`/`CHECK`/`PRIMARYKEY` map to the same sentinels as the Postgres package's SQLSTATE codes, disambiguated by the same DDL constraint names (not by table/column position, which can drift independently between the two schemas). Enforcement site: the translation table, verified by the conformance suite's sentinel-parity assertion across both backends for the same logical condition.\n\n## Non-goals\n\n- LT-38 (the conformance suite itself) is not this pair's story to write — but its assertions are cited above as the actual enforcement site for several criteria in both. If LT-38 hasn't landed by the time LT-36/LT-37 are otherwise ready, those criteria are pending, not waived — flagged explicitly in the PO review script below, not silently marked done.\n- No handler/API-layer work — `internal/api` calling into these packages is a later story.\n- No production connection-pool tuning, migration-execution wiring, or observability — infra/DevOps scope.\n\n## PO review script\n\n1. Confirm both PRs build and their own unit tests pass in CI (once 04's pipeline exists — flag as pending otherwise, per LT-34's precedent).\n2. Confirm the conformance suite (LT-38, if it exists yet) runs against both backends in CI and is green; if LT-38 hasn't been pulled yet, explicitly mark every criterion above whose enforcement site is \"the conformance suite\" as **pending**, not accepted — do not accept LT-36/LT-37 on code review alone for those criteria.\n3. Grep both packages for `strings.Contains` applied to an error value — must return nothing.\n4. Spot-check the `Upsert` SQL/query in both packages for the `created_at`-exclusion; confirm a unit test exists per backend.\n5. For LT-36: confirm the `withRetry` wrapper's engine-conditional behavior in code, and confirm `Search`'s implementation has no retry-wrapper call.\n6. For LT-37: read the SQLite search implementation's doc comment for the non-ASCII case-folding exception; confirm it's stated, not silent.\n7. Confirm neither package's tests or logs contain a literal DB error string with embedded values (spot-check by triggering one constraint violation locally and reading what gets logged).\n\n## Research team review\n\n**Desmond Okafor — claims check:** [pending]\n\n**Tobias Lindqvist — objection:** [pending]\n\n**Naomi Voss — ruling:** [pending]\n"

Fixed on both affected bullets. Also flagged that four LT-38-dependent bullets used present-tense \"the conformance suite exercises/verifies\" language that reads as already-live when LT-38 doesn't exist yet as a pulled story — fixed by rewording each to explicit \"pending LT-38, not yet enforceable\" framing at the point of the claim, not only in the Non-goals section. Sentinel-translation dual-citation and the F50 citation both checked out as correct.\n\n**Tobias Lindqvist — objection:** The document correctly flagged individual criteria as pending when LT-38 doesn't exist, but never stated what that means for the *story's* overall status in `backlog.md` — a PO under pressure could mark the story Done with a footnote, and the footnote is exactly what gets missed when 04 later reads `backlog.md` to decide what's shippable. Counter-proposal accepted: added a hard rule to Non-goals that LT-36/LT-37 sit in an explicit `implemented, verification pending LT-38` state, distinct from both `in progress` and `Done`, until LT-38 lands and every cited criterion actually passes.\n\n**Naomi Voss — ruling:** All three fixes applied. This refinement is accepted and ready to hand off. Net effect of this review round: the doc is now honest about a real sequencing gap (LT-38 isn't pulled yet, so roughly half of what would make LT-36/LT-37 mechanically verifiable doesn't exist yet) rather than either hiding that gap or blocking on it — LT-36/LT-37 can still be implemented and partially verified now (code-review-checkable criteria), with the LT-38-dependent proof explicitly deferred and the story's status prevented from rounding up to Done in the meantime."

78:## S5. Conformance suite (05's requirement, cross-backend) (LT-38)
79-
80-**Description:** One suite, written once against the `Repository` interfaces, run against every backend implementation (postgres, cockroachdb, sqlite) — not per-package unit tests, per `multi-db-strategy.md` §7 and `decisions/multi-db-abstraction.md`. This is the enforcement site for every guarantee in 05's contract that can't be a DDL constraint: identical `Search` result sets/ordering across backends (closing the documented SQLite `LIKE` case-sensitivity correctness gap, not a performance one), sentinel parity via `errors.Is` for every condition in §4, the secret-state rules (§5/§6.11), `is_active` enforcement (§6.10), and empty-string rejection on every `*string` filter.
81-
82-**Acceptance criteria:**
83-- [ ] The suite is written once against the interface and executed against all three backends from one test file/table, not duplicated per package.
84-- [ ] Asserts identical `Search` result sets and ordering across backends for ASCII input — enforcement site: this suite is the enforcement site named in `multi-db-strategy.md` for this guarantee; there is no other.
85-- [ ] Asserts `errors.Is` sentinel parity for every condition in the §4 translation table, across all three backends.
86-- [ ] Asserts the `requires_secret`/`secret_state` relationship (§6.11) and `is_active` (§6.10) — the two conditions 05 named as unable to have a DDL enforcement site.
87-- [ ] CI (04's pipeline) runs this suite against every backend including CockroachDB, not just Postgres+SQLite — flagged to 04 if their pipeline doesn't.
88-
89-**Depends on:** S3, S4.
90-**Model/effort:** sonnet, high.
91-**Type:** Story.

96-## S6. REST handlers: search/retrieve user_profile (Q2) (LT-39)
97-
98-**Description:** The client-facing handlers in `internal/api` implementing the assignment's Q2 (search and retrieve `user_profile`), built against S2's interfaces (fakes stand in for a real backend per `decisions/test-double-strategy.md`, so this doesn't wait on S3/S4). Implements the object-level `authorize(sub, scope, target)` call as an explicit in-handler step, not a second middleware, per the ruling in `handoff-03-auth.md` v3 (my own answer, confirmed by 02).
99-
100-**Acceptance criteria:**
101-- [ ] Implements `handoff-03-auth.md` v3's scope vocabulary and pagination/rate-limit numbers without re-deriving 02's authz-scoping reasoning.
102-- [ ] `authorize()` runs as an explicit call inside each handler after request parsing, before the DAO call — enforcement site: handler code structure, per the go-layout-debate.md-adjacent ruling recorded in this track's reply to 02. `authorize()` checks the `caller_referral`/caller-role data against the token-issuer's own datastore, not against 05's schema — 05 was never assigned that table (`handoff-03-auth.md` v3, F8).
103-- [ ] `profile:search` responses carry masked PII fields by default (e.g. phone as `***-***-1234`, address reduced to `locality`/`region` only); unmasked detail requires a separate, separately-audited follow-up call under `profile:read:own` or `profile:read:any` against the specific record id — enforcement site: the search-response serialization path, distinct from the read-response one (`handoff-03-auth.md` v3, resolves F6).
104-- [ ] Cursor-based pagination only, default page size 20, hard ceiling 50 — enforcement site: the pagination parameter parsing, rejecting any offset-based parameter. **The handler's 20/50 is the authoritative clamp, enforced before the DAO is ever called** — the DAO's own `Limit` bound (1..100, default 50 per `multi-db-strategy.md`) is a second, independent backstop only reachable if the handler clamp is bypassed, not a second policy a caller can rely on (consistency-pass F10: no document previously said which of the two governs).
105-- [ ] A search request with no filter field at all is rejected by this handler before it reaches the DAO — the DAO itself treats an all-nil `ProfileQuery` as legal (`multi-db-strategy.md`), so this handler-layer rejection is the only enforcement site for "no bare unconstrained search" (consistency-pass F10, other half owned by 02 in `handoff-03-auth.md`).
106-- [ ] A `profile:search` query is rejected outright, not truncated, if it would exceed the result cap unconstrained (e.g. a bare wildcard) — enforcement site: this handler's query-validation step, per `handoff-03-auth.md` v3's scope table (consistency-pass F52).
107-- [ ] Unmapped DAO errors never surface `err.Error()` to the client; only the mapped sentinels' safe messages do — enforcement site: the boundary translation function from `decisions/error-semantics.md`. Authn failures (missing/invalid token) return 401; scope failures and `authorize()` policy denials both return 403 with an identical client body, distinguished only in the audit log (`decisions/error-semantics.md`, consistency-pass F7).
108-- [ ] `profile:read:any` requests carry a `reason_code` from the closed enum on every call, logged with the audit record.

## 7. The conformance suite — a requirement, not a suggestion

**Two different checks are easy to conflate here, and §7 previously named only one of them while implying both.** The distinction came from 03 during implementation and is adopted:

| | What it checks | How | Owner |
|---|---|---|---|
| **Signature conformance** | The Go declarations match §2–§3 | Mechanical diff against §3 **with §1a's `model.` substitution applied** — seam 13, not a review | 03's QA, at LT-35 |
| **Behavioural conformance** (this section) | The backends *behave* alike | One suite of assertions, written once, executed against every backend | 03, at the DAO-behaviour story |

**Signature conformance cannot substitute for behavioural conformance, and passing the first says nothing about the second.** Two implementations can match the same declarations perfectly and return different rows for the same call — which is precisely what would have happened here, three separate times, had design not caught it. Ticking §7 by running a signature diff would leave the per-driver ruling resting on nothing.

**One suite, written once against the interface, executed against every backend implementation.** Not per-package unit tests: the same assertions, run twice, so a behavioural difference fails a test rather than reaching a user.

This is the condition the whole per-driver ruling rests on (`decisions/multi-db-abstraction.md`). Two implementations behind one interface guarantee both *compile*; nothing guarantees they *behave* alike, and the failure mode produces no error — just different results. Every defect this phase found (the `LIKE` case divergence, the collation ordering divergence, `Country` normalization) is invisible when either implementation is read in isolation, because each is correct on its own terms.

Mechanism is 03's. The requirement is 05's, and at minimum the suite asserts: identical result sets and identical ordering for the same `Search` across backends; `errors.Is` sentinel parity for every error condition in §4; the secret-state rules in §5 and §6.10; empty-string rejection on every `*string` filter; and for the retention methods in §3c —

- a zero-value `RetentionClass` (`""`) returns `ErrInvalidArgument` — a caller-reachable invalid input, unlike `ErrAlreadyExists`, and therefore owed an explicit assertion rather than only prose;
- `maxRows` outside `1..10_000` returns `ErrInvalidArgument`;
- `OldestSurvivingAt` is non-nil when rows remain and nothing was old enough to delete, and nil **only** when the class is empty;
- `Drained` is false while deletable rows remain at the batch limit and true on the final batch;
- every delete writes exactly one `deletion_log` row in the same transaction, with the reason code the *method* asserts;
- an already-cancelled context returns before deleting anything;
- `deletion_log` carries no PII-shaped column (§6.11).

---

*AI tooling note: this contract was produced by Claude Opus 5 (05 track-lead session) synthesizing two orchestrated debates run with four Claude Sonnet 5 hires — a three-hats run on the abstraction and an adversarial pair on the query shape, artifacts under `decisions/` — plus one lead-authorized Sonnet research pass (`research-cockroachdb-postgres-semantics.md`) and a direct two-party agreement with the 03 track lead on the factory shape. Six of the eleven substantive changes in it came from hires contradicting the lead's draft, which is what the seats were bought for.*

41:`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.
187:**`SecretState` is new and is the fix for a real defect.** The previous prose said `secret` was "nullable, salted hash only" and stopped. Yusuf Karadag's review found that at least three distinct states were collapsing into one null — the method requires no server-held secret (passkey/WebAuthn, where the private key is client-side), the secret is not yet set, or the secret was revoked — and that `auth_method.requires_secret` was consequently load-bearing on nothing. An explicit state column makes the three distinguishable and gives `requires_secret` something to be checked against.
455:| `requires_secret` | `bool` | BOOLEAN / INTEGER 0-1 | NOT NULL | `false` for passkey/WebAuthn-style methods |
456:| `is_active` | `bool` | BOOLEAN / INTEGER 0-1 | NOT NULL | |
495:6. **UUID primary keys on every backend.** Required for CockroachDB (sequential keys create write hotspots on a single range), supported on Postgres, app-generated on SQLite. Settled by sourced research; do not reopen. *Enforcement: the column types in §5.*
499:10. **`is_active` on `auth_method`.** `ErrInvalidMethod` is documented as "unknown **or inactive**", and the foreign key catches only *unknown* — a cold read applied item 11's own standard back to this document and found it failing its test. `is_active = false` has no DDL enforcement site and cannot have one, for the same reason as item 11: a `CHECK` on `user_credential` cannot read `auth_method`. *Enforcement: the DAO checks `is_active` before insert and returns `ErrInvalidMethod`, plus a conformance test that creates a credential against a deactivated method and asserts the sentinel.* Deactivating a method deliberately does **not** invalidate existing credentials — it prevents new ones.
501:12. **The `requires_secret` ↔ `secret_state` relationship.** A credential whose method has `requires_secret = false` must not carry `secret_state = 'set'`. **This one cannot be a DDL constraint** — `CHECK` cannot reference another table — so its enforcement site is DAO-layer validation returning `ErrInvalidCredential`, plus a conformance test. Named honestly as one of the two weakest sites in this contract (the other is item 10, `is_active`), because the discipline is worthless if it only records the cases where a clean site existed.
518:Mechanism is 03's. The requirement is 05's, and at minimum the suite asserts: identical result sets and identical ordering for the same `Search` across backends; `errors.Is` sentinel parity for every error condition in §4; the secret-state rules in §5 and §6.10; empty-string rejection on every `*string` filter; and for the retention methods in §3c —
526:- `deletion_log` carries no PII-shaped column (§6.11).

486	## 6. Out of scope for 03 — do not redesign; flag to 05 instead
487	
488	Numbered so there is no ambiguity. Each names **the enforcement site that makes it hold**, per the principle adopted in `decisions/search-query-shape.md`: *a guarantee with no named enforcement site is not a guarantee, it is a hope.*
489	
490	1. **PII/credential separation.** `user_credential` carries no name, phone or address; `user_profile` carries no secret. This is a governance control, not normalization convenience — a breach of one table must not expose the other class of data (`pii-governance.md`). *Enforcement: the column sets in §5, the three-accessor split in §1, and a conformance test asserting neither struct gains a field from the other.*
491	2. **Cascade delete from profile to credential, and its asymmetry.** Deleting a profile destroys its credentials; the account ceases to exist. **The reverse does not hold** — deleting a credential leaves the profile and its PII standing on the `direct` retention clock. Deliberate. If "removing your last credential deletes the account" is wanted, that is a product policy decision, not a schema one, and it is currently *not* what the schema does. *Enforcement: `ON DELETE CASCADE` on the FK; the asymmetry is stated in `pii-governance.md`.*
492	3. **Case, collation and folding.** `ORDER BY LOWER(name) COLLATE "C" ASC, id ASC`, fixed and not caller-configurable, with collation named in DDL as well — `COLLATE "C"` on Postgres, `BINARY` on SQLite. Without this, page 1 of a search returns *different rows* per backend, because Postgres sorts by database collation while SQLite's default byte order puts every uppercase letter before every lowercase one. Cost accepted and named: `C` is byte order, so non-English names sort in an order a human would call wrong — identical-across-backends beats locale-pretty for a system whose whole premise is one contract over three engines. *Enforcement: the DDL collation clause, the `ORDER BY` expression, and a conformance test asserting identical ordering across backends.*
493	4. **`LIKE` escaping.** The DAO escapes `%`, `_` and `\` in caller input and emits an explicit `ESCAPE '\'` on both backends — Postgres has a default backslash escape, SQLite has none unless given. Without this, a search for `50%` matches every row. *Enforcement: the DAO's query construction, plus a conformance test using a term containing `%`.*
494	5. **`Country` normalization at write, not only at read.** Upper-casing the query without upper-casing the table makes a stored `us` silently invisible to a search for `US`. SQLite's `upper()` is ASCII-only — sufficient for alpha-2 codes, written down so nobody assumes it generalizes. *Enforcement: the `CHECK` constraint in §5 plus write-side normalization in both implementations.*
495	6. **UUID primary keys on every backend.** Required for CockroachDB (sequential keys create write hotspots on a single range), supported on Postgres, app-generated on SQLite. Settled by sourced research; do not reopen. *Enforcement: the column types in §5.*
496	7. **`auth_method` as a lookup table, not a native enum.** Adding a method is an `INSERT`, not a migration and not a deploy. *Enforcement: the FK from `user_credential.method_id`; see `migration-approach.md` §4.*
497	8. **The `ON CONFLICT ... DO UPDATE` upsert form.** The one syntax all three backends accept; CockroachDB's `UPSERT` shorthand is deliberately unused to avoid a second dialect. *Enforcement: `Upsert`'s single query shape.*
498	9. **The two-package split** (`postgres` serving Postgres + CockroachDB, `sqlite` separate) and the engine-aware retry seam inside the former. *Enforcement: package boundaries; `decisions/multi-db-abstraction.md`.*
499	10. **`is_active` on `auth_method`.** `ErrInvalidMethod` is documented as "unknown **or inactive**", and the foreign key catches only *unknown* — a cold read applied item 11's own standard back to this document and found it failing its test. `is_active = false` has no DDL enforcement site and cannot have one, for the same reason as item 11: a `CHECK` on `user_credential` cannot read `auth_method`. *Enforcement: the DAO checks `is_active` before insert and returns `ErrInvalidMethod`, plus a conformance test that creates a credential against a deactivated method and asserts the sentinel.* Deactivating a method deliberately does **not** invalidate existing credentials — it prevents new ones.
500	11. **`deletion_log` carries no PII.** It exists to prove a deletion happened after the row is gone; a log containing the name and address of everyone whose data was deleted would be the retention policy's own failure mode wearing an audit trail's clothes. `profile_id` deliberately has no FK, because the row it names is meant not to exist. *Enforcement: the column set in §5, plus a conformance test asserting no PII-shaped column exists on the table.*
501	12. **The `requires_secret` ↔ `secret_state` relationship.** A credential whose method has `requires_secret = false` must not carry `secret_state = 'set'`. **This one cannot be a DDL constraint** — `CHECK` cannot reference another table — so its enforcement site is DAO-layer validation returning `ErrInvalidCredential`, plus a conformance test. Named honestly as one of the two weakest sites in this contract (the other is item 10, `is_active`), because the discipline is worthless if it only records the cases where a clean site existed.

  "content": "# LT-38 refinement — S5: conformance suite (cross-backend behavioral conformance)\n\n**Product Owner:** Naomi Voss (01). **Research team:** Imogen Hale, Desmond Okafor, Tobias Lindqvist. **Engineering:** Renata Cole (03). **Source:** `03-engineering-delivery/backlog.md` S5 (LT-38).\n\n**Who did the work:** Refined by Naomi Voss (PO); claims check Desmond Okafor; objection Tobias Lindqvist; engineering counterpart Renata Cole.\n\n## Why pulled now\n\nLT-36 and LT-37's refinement (see `refinement/LT-36-LT-37.md`) cited this suite as the sole enforcement site for roughly half their own acceptance criteria and added a hard rule that neither story can be marked Done until LT-38 lands and those criteria actually pass. Pulling LT-38 now is what closes that gap — it's the next dependency in the chain (`Depends on: S3, S4`), and refining it now means it's ready to run the moment either backend PR lands, rather than sitting as a bottleneck after the fact.\n\n## Correction found before drafting (citation error in `backlog.md` itself, not introduced here)\n\n`backlog.md`'s S5 description cites \"the secret-state rules (§5/§6.11)\" for the `requires_secret`/`secret_state` relationship. Checked against `multi-db-strategy.md` directly: **§6.11 is item 11 in §6's numbered list — \"`deletion_log` carries no PII\" — a different guarantee entirely.** The `requires_secret`/`secret_state` relationship is item 12 (unlabeled with an explicit \"§6.12\" in the source doc's own prose, but numerically next in the same list, referred to there only as \"item 12\"). `is_active`'s citation as §6.10 is correct — that one checks out exactly. Fixed below by citing item 12 correctly and not repeating the backlog's §6.11 mislabel.\n\n## Acceptance outcome\n\nNo public-URL surface (same as LT-35/36/37) — this is a test suite, not a deployable behavior change. \"Done\" means the suite exists once, runs against all three backends from one table-driven test, and every guarantee below is asserted as a specific, named test case (not a general \"seems to work\" pass) — modeled on the frozen-checksum-plus-structural-diff pattern Oren built for LT-35's conformance test, since 05's own §7 explicitly warns that signature conformance (LT-35) proves nothing about behavioral conformance (this story) — two implementations can match every declaration and still return different rows for the same call.\n\n## Acceptance criteria (restated from `backlog.md` S5, corrected and expanded)\n\n- [ ] The suite is written once against the `Repository` interface and executed against all three backends (postgres, cockroachdb, sqlite) from one table-driven test file, not duplicated per package. Enforcement site: a single test function parameterized over backend, not three near-identical copies.\n- [ ] Asserts identical `Search` result sets and ordering across backends for ASCII input — this suite is `multi-db-strategy.md`'s named enforcement site for this guarantee; there is no other. Named test case: a fixed dataset seeded identically on all three backends, a fixed query, asserting row-for-row identical results and order.\n- [ ] Asserts `errors.Is` sentinel parity for every condition in the §4 translation table, across all three backends — named test case per condition (not one combined test), consistent with LT-36/LT-37's \"not-Done-until-LT-38\" dependency: this is the specific enforcement site those stories were waiting on.\n- [ ] Asserts the `requires_secret`/`secret_state` relationship (§6, item 12 — corrected citation, see above) as a named test: creating a credential with `secret_state = 'set'` against a method whose `requires_secret = false` returns `ErrInvalidCredential`, on all three backends.\n- [ ] Asserts `is_active` enforcement (§6.10) as a named test: creating a credential against a deactivated `auth_method` returns `ErrInvalidMethod`, on all three backends — per the doc's own note that deactivation must not invalidate *existing* credentials, so the test also asserts an existing credential against a since-deactivated method still reads back successfully.\n- [ ] Asserts empty-string rejection on every `*string` filter field in `ProfileQuery` — one named test case per field (`Name`, `Phone`, `Region`, `Country`), not one combined test, per the \"absent, never empty\" convention.\n- [ ] Retention/deletion assertions from `multi-db-strategy.md` §7's own minimum list, each as a named test case: a zero-value `RetentionClass` (`\"\"`) returns `ErrInvalidArgument`; `maxRows` outside `1..10_000` returns `ErrInvalidArgument`; `OldestSurvivingAt` is non-nil when rows remain (including when nothing was old enough to delete) and nil only when the class is empty; `Drained` is false while deletable rows remain at the batch limit and true on the final batch; every delete writes exactly one `deletion_log` row in the same transaction with the reason code the method itself asserts; an already-cancelled context returns before deleting anything; `deletion_log` carries no PII-shaped column (§6.11 — correctly cited here, this is the actual §6.11 guarantee).\n- [ ] The CockroachDB-specific retry path is exercised for real: at least one test forces a genuine SQLSTATE `40001` (e.g. two concurrent transactions racing on the same row) against a real CockroachDB instance/testcontainer and asserts the operation succeeds after retry, not a mocked retry.\n- [ ] CI (04's pipeline) runs this suite against every backend including CockroachDB, not just Postgres+SQLite — flagged to 04 if their pipeline configuration doesn't do this; enforcement site is the CI job matrix/config itself, not this suite's own code.\n- [ ] Following the model Oren built for LT-35: the suite's test data / expected-behavior assertions state, in a comment, which parts are derived directly from `multi-db-strategy.md`'s prose (the guarantees list in §7 and the numbered items in §6) and, where practical, carry the same frozen-copy-plus-checksum protection so a later revision to those sections forces a human re-check rather than the suite silently asserting a stale guarantee. Scoped down from LT-35's version since this suite asserts *behavior*, not *signatures* — a full checksum-gated transcription may not be practical for prose guarantees the way it was for Go signatures; at minimum, each test case's doc comment names the specific `multi-db-strategy.md` line/item it enforces, so a future doc change is at least greppable.\n\n## Non-goals\n\n- No new backend implementation — this story only tests LT-36/LT-37's output.\n- No handler/API-layer testing — that's LT-39 and later, against fakes per `decisions/test-double-strategy.md`, not this suite.\n- No performance/load testing — \"identical\" here means identical correctness (rows, order, errors), not identical latency; SQLite's full-table-scan search is explicitly *not* required to be as fast as Postgres's indexed search, only as correct.\n\n## PO review script\n\n1. Confirm the suite is one table-driven test executed against all three backends, not three copies (read the test file structure).\n2. Confirm each guarantee above has its own named test case (grep test names against the list) — not one broad \"conformance\" test that silently covers several guarantees and can't tell you which one failed.\n3. Confirm the CockroachDB retry test forces a real `40001` against a real CockroachDB instance, not a mock — read the test setup.\n4. Confirm CI's job matrix actually includes CockroachDB as a target, not just Postgres+SQLite (04's pipeline config, once it exists).\n5. Once LT-36 and LT-37 are both implemented and this suite runs against them: confirm it's actually green on all three backends, and go back and mark the LT-38-dependent criteria in LT-36/LT-37's refinement doc as accepted, updating both stories out of \"implemented, verification pending LT-38\" status.\n\n## Research team review\n\n**Desmond Okafor — claims check:** [pending]\n\n**Tobias Lindqvist — objection:** [pending]\n\n**Naomi Voss — ruling:** [pending]\n"

# Deploy Path — Discovery Findings

Written per team-lead's agile-loop brief. Answers: how do we reach the cluster, how does GitHub Actions get code onto it, what does the public URL look like.

## 1. What the cluster actually is — correction to the planning-phase narrative

The planning-phase docs (`../PLAN.md`, `handoff-04-secrets.md`) described the deployment target as a "lab/dev cluster" reachable only through an external operator agent ("amber-kubernetes"). Direct discovery on this machine found something more specific and more consequential:

- This machine already holds a working `kubectl` context (`dev`, cluster `uplift-kub`, 5 nodes, `kubeconfig` at `~/.kube/config`) with direct access — no SSH hop, no operator agent needed to *reach* it.
- The "OpenClaw CI/CD in Kubernetes dev cluster" session named in the brief is not currently listed by `ListAgents` — not contacted, since direct access already exists and answers the question it would have answered.
- **This is a real, live, multi-tenant cluster, not an isolated sandbox.** Namespaces include `bitwarden` (Warren's actual password manager, `bitwarden.uplifttech.org`), `homeassistant`, `kafka`, `cert-manager`, `backup`, and several real business sites (`salemforensics.com`, `mc.uplifttech.org`/`acrimoniousmc.com`, `calcom.uplifttech.org`, `floracore.uplifttech.org`). All public-facing services follow one pattern: an `Ingress` (class `nginx`) under a real hostname, TLS via `cert-manager`'s `letsencrypt-prod` `ClusterIssuer`, routed through one shared `ingress-nginx-controller` `Service` (`LoadBalancer`, internal IP `192.168.1.200`, presumably port-forwarded to the internet at the router — not verified from here, and not something to change).
- **Confirmed with Warren directly before proceeding** (this track paused and asked, given the mismatch between the planning-phase "isolated lab cluster" framing and what discovery found): deploy to this real cluster, in an isolated namespace, with a public tunnel/URL, is approved.

**Consequence for this design:** every prior "lab cluster, nothing at stake" assumption is replaced with "shared production infrastructure serving real, unrelated services — isolate aggressively." Namespace, RBAC, and resource limits below are sized for that, not for a sandbox.

## 2. GitHub Actions → cluster: self-hosted runner already exists

GitHub-hosted runners can't reach a LAN cluster; the choice is a self-hosted runner or GitOps pull. **This cluster already runs Actions Runner Controller (ARC):**
- `arc-system` namespace: `arc-gha-rs-controller` (the ARC controller itself).
- `arc-runners` namespace: an `AutoscalingRunnerSet` named `k8s-linux-x64` (min 1, max 4 runners), with one runner Pod live.

This runner set's current GitHub registration target (which org/repo it's scoped to) isn't determined from here without reading a Secret, and isn't assumed to already point at `wtvamp/loginid-takehome` — that's a question for whoever manages this ARC install, not something to touch. **Decision: do not repurpose the existing runner set.** Deploying this take-home's images and manifests needs a `kubectl apply` from inside the cluster's network with a scoped ServiceAccount — reusing an already-provisioned runner set that may serve other repos/workloads would mean this take-home's deploy job runs with whatever permissions that runner already has, which is exactly the shared-blast-radius problem this project's own designs (NetworkPolicy, RBAC-per-service) have been arguing against. Instead: **a second, narrowly-scoped `AutoscalingRunnerSet`**, registered to `wtvamp/loginid-takehome` specifically, in its own namespace, with a ServiceAccount whose RBAC is limited to the take-home's own namespace only (`get`/`list`/`create`/`update`/`patch` on `Deployments`/`Services`/`Ingresses`/`NetworkPolicies`/`Secrets`-by-name in that namespace, nothing cluster-scoped). This is additive to the cluster's existing ARC controller (one controller can run multiple scale sets), not a competing install.

## 3. Namespace and isolation

New namespace: `loginid-takehome`. Everything in `./containerization-design.md`'s manifests (both Deployments, the issuer Deployment, both Services, the `NetworkPolicy`) targets this namespace, not the placeholder `loginid-poc` used in the design-phase sketch — that name gets corrected in this pass. Resource limits from `./containerization-design.md` stay as designed (they were sized for "a two-service take-home," which is even more clearly correct now that the cluster is shared with real workloads, not less). A `ResourceQuota` on the namespace is a cheap additional backstop worth adding given the shared-cluster finding — caps total CPU/memory the whole take-home can ever consume regardless of what any single manifest requests.

## 4. Public URL

Following the cluster's existing, uniform pattern rather than inventing a new one (a Cloudflare Tunnel or similar was the planning-phase's guess; the cluster doesn't use one — every existing public service is a plain `Ingress` + `cert-manager` + the shared `ingress-nginx` `LoadBalancer`):

- **Ingress host:** `loginid-takehome.uplifttech.org`, `Ingress` class `nginx`, TLS via `letsencrypt-prod`, matching every other app in the cluster.
- **Open item, not resolvable from this session:** the DNS record for that hostname doesn't currently resolve (checked; no answer). Either it needs adding at whatever DNS provider hosts `uplifttech.org` (Warren's call — this track has no DNS credentials and isn't requesting them) or it already resolves via a wildcard this check didn't hit correctly; needs one confirmation before the first deploy's public URL is real rather than theoretical. Flagging to Naomi/PO and Dana now rather than discovering it at the acceptance-script step.
- **Routes:** `/api/*` (or a path prefix TBD with 03) → `api-service`; the issuer's endpoints (`/auth/token`, `/.well-known/jwks.json` or similar, per 02/03's final route naming) → `api-service-issuer`. `idp-connector` gets no route — it's never publicly reachable, per its own design.
- **Acceptance-script shape this enables:** `https://loginid-takehome.uplifttech.org/healthz` (and an equivalent connector-side path if 03 exposes one) returning up + the deployed commit SHA, per team-lead's target script — `/healthz` already exists in the containerization design and 03's `internal/app` build-info work (per PM's note on LT-34) is what supplies the SHA.

## 5. What this changes in `./containerization-design.md` (applied in this pass)

- `namespace: loginid-poc` → `namespace: loginid-takehome` throughout.
- New `Ingress` resource (host above, TLS via `letsencrypt-prod`) added alongside the existing Services.
- A namespace-level `ResourceQuota` added as a backstop.
- Everything else (two Deployments, the issuer split, `NetworkPolicy`, resource limits per container, the migration `Job`) is unchanged — those were designed correctly for "shared infrastructure, isolate aggressively" even under the earlier, wrong assumption that this was a private sandbox.

## 6. CI/CD sequencing (per team-lead's split)

The PR-check workflow (lint, build, `-race` tests, `govulncheck`) needs none of the above and ships first, on GitHub-hosted runners — no cluster access required. The merge-to-main workflow (build+push images to GHCR, apply manifests via the new scoped runner set, print the public URL + commit SHA in the job summary) follows once the runner set and namespace exist. Both live at `.github/workflows/` at the repo root.

---
*AI tooling note: discovery run directly by Theo (Sonnet, this session) via `kubectl`, `dig`, and `ListAgents` — no external operator agent contact was needed or made. Confirmed with Warren directly (AskUserQuestion) before treating the real-cluster finding as a green light, given the mismatch with the planning-phase framing.*

  "content": "# LT-45 / LT-47 refinement — containerization + K8s manifests, and CI/CD pipeline\n\n**Product Owner:** Naomi Voss (01). **Research team:** Imogen Hale, Desmond Okafor, Tobias Lindqvist. **Engineering:** Theo Bergman (04). **Source:** `04-infra-devops/backlog.md` Story 1 (LT-45) and Story 3 (LT-47); `04-infra-devops/decisions/deploy-path.md` (Theo's discovery).\n\n**Who did the work:** Refined by Naomi Voss (PO); claims check Desmond Okafor; objection Tobias Lindqvist; engineering counterpart Theo Bergman.\n\n## Why pulled as a pair, and why now\n\nLT-34 is implemented and merged but not Done — it becomes Done only once deployed and reviewable at a public URL, and that deploy path is exactly LT-45 (manifests) + LT-47 (the pipeline that applies them). This pair is the unblock for the whole agile-loop bar (\"done = deployed\"), not just two more stories in the queue — every story behind it (LT-35/36/37/38's eventual deploy, LT-34's own closure) is waiting on this landing.\n\n## Correction to the original story text, discovered by Theo (not assumed here)\n\nBoth `backlog.md` stories were written against a \"lab cluster reached via a public tunnel\" assumption from planning. Discovery found the real target: **Warren's actual home/production Kubernetes cluster** (`uplift-kub`, 5 nodes), shared with real unrelated workloads (Bitwarden, Home Assistant, several live business sites) — not an isolated sandbox, and not fronted by a tunnel but by a standard `nginx` `Ingress` + `cert-manager` pattern already used by every other app on the cluster. Confirmed directly with Warren before proceeding (`decisions/deploy-path.md` §1). This refinement is written against the real target, not the planning-phase placeholder — LT-45's acceptance criteria below reflect `namespace: loginid-takehome` (not the design-phase placeholder `loginid-poc`), the added `Ingress` and `ResourceQuota`, and a second, narrowly-scoped GitHub Actions runner set rather than repurposing the cluster's existing shared one.\n\n**Flagging for the record, not a blocker:** this is a materially higher-stakes deploy target than \"an isolated lab cluster\" — a misconfigured `NetworkPolicy`, an over-broad RBAC grant, or an unbounded resource request on this take-home's manifests has a real, if contained, blast radius against Warren's own production services. The isolation measures below (dedicated namespace, scoped RBAC, `ResourceQuota`, `NetworkPolicy` default-deny) are the mitigations Theo's already designed for exactly this; this refinement's acceptance criteria treat them as load-bearing, not optional hardening.\n\n## Acceptance outcome (LT-45 + LT-47 together = the first end-to-end vertical slice)\n\n\"Done\" for this pair, concretely: `https://loginid-takehome.uplifttech.org/healthz` (on `api-service`) returns HTTP 200 with `{\"status\":\"ok\",\"service\":\"api-service\",\"build\":\"<commit-sha>\"}`, and the same for `idp-connector`'s equivalent path if it's given one — reachable by anyone with the URL, no VPN, no kubeconfig. This is LT-34's own review script, finally executable.\n\n**Open item, not yet resolved — flagged here so it isn't a surprise at review time:** the DNS record for `loginid-takehome.uplifttech.org` doesn't currently resolve (per `decisions/deploy-path.md` §4). This story cannot be accepted as Done until it does — that's a hard dependency, not a nice-to-have, since \"reviewable at a public URL\" is the whole bar. Owner of the DNS fix is whoever manages `uplifttech.org`'s DNS (Warren, per Theo — this track has no DNS credentials and isn't requesting them).\n\n## LT-45 acceptance criteria (restated from `backlog.md`, corrected for the real cluster)\n\n- [ ] Both images build multi-stage (distroless final stage, non-root, read-only root filesystem) and contain nothing but the binary (+ CA certs for `idp-connector`). Enforcement site: the Dockerfile's final `COPY` list.\n- [ ] Neither Pod can write its own root filesystem at runtime. Enforcement site: `securityContext.readOnlyRootFilesystem: true`.\n- [ ] `idp-connector` is unreachable except from `api-service` — enforced by a **default-deny `NetworkPolicy`**, since the cluster's namespace default is allow, not deny; this is not optional hardening on a shared cluster. Enforcement site: the `NetworkPolicy` ingress rule scoped to `api-service`'s pod selector.\n- [ ] The JWT signing private key is mounted only into `api-service-issuer`'s Deployment, never `api-service`'s own — enforcement site: `api-service`'s manifest carries no volume/mount referencing that `Secret`, verified by manifest inspection, not RBAC alone.\n- [ ] All manifests target `namespace: loginid-takehome` (corrected from the design-phase placeholder `loginid-poc`) — enforcement site: every manifest's `metadata.namespace`, grepped for the old placeholder returning nothing.\n- [ ] A namespace-level `ResourceQuota` caps total CPU/memory the whole take-home can consume, independent of any single manifest's own `resources.limits` — added specifically because this is shared production infrastructure, per `decisions/deploy-path.md` §3. Enforcement site: the `ResourceQuota` object itself, applied to the namespace.\n- [ ] A public `Ingress` (class `nginx`, TLS via `letsencrypt-prod`) routes `/healthz` (and whatever path prefix 03 finalizes for the rest of the API) to `api-service`, and issuer-specific routes to `api-service-issuer`. `idp-connector` gets **no route** — never publicly reachable, per its own design. Enforcement site: the `Ingress` resource's path rules.\n- [ ] The migration `Job` runs with `parallelism: 1` and is gated by the CI pipeline's concurrency mechanism (LT-47), not Kubernetes ordering alone.\n- [ ] The GitHub Actions deploy step uses a **second, narrowly-scoped `AutoscalingRunnerSet`** registered specifically to `wtvamp/loginid-takehome`, with RBAC limited to the `loginid-takehome` namespace only (no cluster-scoped permissions) — **not** the cluster's existing shared runner set, per `decisions/deploy-path.md` §2's blast-radius reasoning. Enforcement site: the runner set's own RBAC manifest, scoped by namespace, reviewed independently of the take-home's application manifests.\n\n## LT-47 acceptance criteria (restated from `backlog.md`, revised for real deploy per the agile-loop bar)\n\n- [ ] A lint or test failure blocks merge — required status check, not advisory.\n- [ ] A CockroachDB-specific SQL incompatibility surfaces at PR time via a dedicated CockroachDB testcontainer job.\n- [ ] Only one migration run can reach the migrate stage at a time, across concurrent deploys — enforced by the pipeline's own concurrency group/mutex on the deploy environment.\n- [ ] No secret enters a build log or image layer — `gitleaks` stage plus the Dockerfile's minimal `COPY` list (LT-45).\n- [ ] **Revised — no longer \"documented but not invoked\":** per Theo's explicit agreement (no objection to full auto-deploy on merge at this take-home's scale, no manual gate requested), the deploy stage actually runs on merge to main — build → push images to GHCR → apply manifests via the scoped runner set → print the public URL and deployed commit SHA in the job summary. This replaces the design-phase criterion that treated deploy as describe-only; that criterion predates the agile-loop bar (\"done = deployed and reviewable at a public URL\") and is now obsolete, not just superseded in emphasis.\n- [ ] The PR-check workflow (lint, build, `-race` tests, `govulncheck`) requires no cluster access and runs on GitHub-hosted runners; only the merge-to-main deploy workflow uses the scoped self-hosted runner set — per `decisions/deploy-path.md` §6's sequencing, so a PR from an untrusted or draft branch never touches cluster credentials.\n- [ ] The job summary on a successful merge-to-main run states the public URL and the deployed commit SHA explicitly, in plain text — this is what makes LT-34's PO review script (and every later story's) executable without a human hunting through logs.\n\n## Non-goals\n\n- No DNS management — the record's existence/correctness is Warren's call, flagged as an open item above, not something this track has credentials to fix.\n- No change to the cluster's existing ARC controller or its other runner sets/workloads — additive only.\n- No production-grade autoscaling, multi-region, or blue/green deploy — a single-replica, single-region deploy is sufficient for this take-home's scale; flag if that assumption is wrong.\n- No change to other namespaces or other apps' Ingress/DNS on this cluster.\n\n## PO review script\n\n1. Confirm the DNS record for `loginid-takehome.uplifttech.org` resolves (a plain `dig`/browser check) — if it doesn't, this story is not accepted, full stop, regardless of what else passes.\n2. `curl -s https://loginid-takehome.uplifttech.org/healthz` — confirm HTTP 200, `{\"status\",\"service\",\"build\"}` only (per 02's ruling, already verified in LT-34's own review), and that `build` is a real commit SHA, not `\"unknown\"`.\n3. Confirm the GitHub Actions job summary for the merge-to-main run states the public URL and the deployed SHA in plain text.\n4. Read the manifests (or the PR diff) for: `namespace: loginid-takehome` everywhere (no `loginid-poc` leftover), the `NetworkPolicy` default-deny + `api-service`-only ingress rule on `idp-connector`, the `ResourceQuota` object, and that `api-service`'s manifest has no mount referencing the JWT signing `Secret`.\n5. Confirm the deploy-stage runner set is the new, narrowly-scoped one (check its RBAC binding's namespace scope), not the cluster's pre-existing shared runner set.\n6. Confirm the PR-check workflow (separate from merge-to-main) runs with no cluster credentials available to it — check the workflow YAML's runs-on/permissions, not just that it passes.\n7. Trigger (or wait for) a second commit's deploy and re-run step 2, confirming the `build` SHA changes — this is LT-34's own freshness check, finally executable end-to-end.\n\n## Research team review\n\n**Desmond Okafor — claims check:** [pending]\n\n**Tobias Lindqvist — objection:** [pending]\n\n**Naomi Voss — ruling:** [pending]\n"

I've written my refinement's acceptance criteria to treat those isolation measures as load-bearing, not optional.

Enforcement site: the document's own existence and completeness, checked against the actual manifest list in the merged PR.\n\nThis is a real, not cosmetic, gap on infrastructure of this kind: everything else in this pair is carefully isolated for launch, but nothing addresses end-of-life. A take-home interview evaluation is time-bounded; a live namespace, a self-hosted runner with cluster-facing RBAC, a public HTTPS endpoint, and a JWT signing key are not, unless something says otherwise. Without a named teardown procedure and owner, the realistic failure mode is exactly the one production infrastructure tends to accumulate: isolation gets audited once at launch and then the whole thing is quietly forgotten, while its attack surface persists indefinitely. The trigger condition itself (when teardown actually happens — a fixed number of days after Warren confirms the interview process has concluded, or on request) is Warren's call, not this track's or this refinement's to set unilaterally — flagged to the PM below for that specific decision; this criterion only requires that the procedure exist and name an owner, not that it fire automatically on a date this refinement invents."
