Fixed by collapsing each into a single statement — `DeleteExpired` now uses `candidates`/`removed`/`logged` CTEs where the `removed` DELETE re-checks the same predicate the `candidates` SELECT used; `DeleteProfile` is now one `DELETE ... RETURNING source` statement. Verified against real Postgres 16 and CockroachDB v23.2.0 (the CTE form required an explicit `RETURNING id` on the `logged` INSERT — CockroachDB rejects a write CTE that returns no columns, Postgres does not enforce this).\n\n2. **Nil-slice JSON serialization** — `Search`, `ListByUserID`, and `List` declared `var results []model.X`, which serializes to `null` for zero matches instead of `[]`. Fixed by initializing to `results := []model.X{}`.\n\nNo other findings — error-sentinel mapping and nullability elsewhere in the diff look correct.\n\nWork-By: Oren Castellan (QA)\nEOF\n)\"",

Fixed with a jittered backoff (`backoffBase` + random jitter up to `backoffBase+backoffJitter`) between attempts, via an injectable `backoffSleep` var so `retry_test.go` can stub it out and stay fast/deterministic. Added `TestRetryLoop_BackoffRespectsCancelledContext` to confirm a cancelled context aborts the backoff wait immediately rather than blocking for the full jittered duration.\n\n2. **`DeleteExpired`'s select-then-loop-delete redid one query per row on retry** — a 40001 partway through a large sweep retried the whole sequential id-by-id delete loop, not just the one query. Resolved as part of Oren's TOCTOU fix on the same method: collapsing it to a single CTE-based statement means a retry now redoes one round-trip, not up to `maxRows` of them.\n\nNo other findings — connection lifecycle and error propagation elsewhere in the diff look correct.\n\nWork-By: Nolan Reyes (QA)\nEOF\n)\"",

Verified it correctly matches every CHECK/UNIQUE/FK/PK condition in the schema, including unnamed CHECKs (which correctly fall through to `ErrInvalidArgument`). Added a doc comment flagging that this is not a stable driver API and naming `TestIntegration_CredentialCRUDAndErrorTranslation`'s exact-sentinel assertion as the thing that would actually catch a future driver message reflow — that test must not be loosened as \"redundant.\"\n\n2. **`DeleteExpired` TOCTOU, same shape as LT-36** — the per-row `DELETE FROM user_profile WHERE id = ?` didn't re-check the retention predicate, so a row that stopped matching between the candidate SELECT and its delete could still be deleted. SQLite has no writable-CTE support (confirmed directly: DML inside `WITH` fails with \"SQL logic error: near DELETE: syntax error\"), so the single-statement CTE form used on Postgres isn't available here. Fixed by re-adding the predicate directly to the per-row DELETE (`WHERE id = ? AND <source predicate> AND <clock column> < ?`) — same intent as the Postgres fix, SQLite-compatible mechanism.\n\n3. **Nil-slice JSON serialization** — same fix as LT-36: `Search`/`ListByUserID`/`List` now initialize to `[]model.X{}` instead of a nil slice.\n\nWork-By: Oren Castellan (QA)\nEOF\n)\"",

Fixed by adding a doc comment on `SetMaxOpenConns(1)` in `sqlite.go` explaining this and scoping it explicitly to this backend's stated dev/demo tier — flagging that the ceiling needs revisiting if that scope ever changes.\n\n2. **`_foreign_keys` DSN change (Amendment A3) — verified correct.** `PRAGMA foreign_keys` is per-connection, not a property of the database file, so a bare post-open `PRAGMA` exec only covered whichever connection ran it and would silently stop covering FK enforcement the moment the pool opened a second connection. Confirmed this matters, not just theoretical: temporarily reverted the DSN param and `TestIntegration_ProfileDeleteCascadesToCredentials` failed. No further action needed — already correctly wired via `withForeignKeysOn(dsn)` appending `_foreign_keys=on`.\n\n3. **No retryable-error class on this backend** — confirmed `New()`'s doc comment is accurate: SQLite has no serialization-failure class analogous to CockroachDB's 40001, so the absence of a retry wrapper here is a deliberate omission, not a gap.\n\nNo other findings — connection lifecycle and error propagation elsewhere in the diff look correct.\n\nWork-By: Nolan Reyes (QA)\nEOF\n)\"",

This is deliberately separate from LT-35's internal/dao/\nconformance_test.go (package dao): LT-35 asserts Go-shape/signature\nconformance — do the three packages compile against the same\ninterfaces — this asserts *behavioral* conformance — do they behave\nalike given the same inputs against a live database. Two packages can\nsatisfy the same Go interface and still diverge in what they actually\ndo; LT-35 cannot catch that, this suite is built to.\n\nCovers, per backend: sentinel-error parity for every dao.Err* (id\nvalidation including the non-canonical-but-well-formed case, duplicate\nusername, invalid method, invalid query, invalid argument, invalid\ncredential), requires_secret/is_active enforcement, cascade/no-cascade\ndelete semantics, DeleteExpired (invalid class, maxRows bounds,\nOldestSurvivingAt nil-vs-non-nil, Drained), exactly-one deletion_log row\nper delete, and an already-cancelled-context deletes-nothing check. Also\nincludes TestConformance_CockroachDB_RealSerializationRetry, which\nforces a genuine SQLSTATE 40001 against real CockroachDB rather than a\nmocked error, to prove the retry path in internal/dao/postgres/retry.go\nactually fires end-to-end, not just against fakeErr() in that package's\nown unit tests.\n\nRebuilt onto main after PR #6 (LT-36) and PR #8 (LT-37) merged: this\nbranch's earlier commit history replayed old, pre-rebase copies of\nthose two branches and produced spurious whole-file conflicts against\ntheir final, already-merged versions, so rather than force through that\nreplay, this commit resets cleanly onto main and re-adds only this\npackage — the one piece of LT-38 that doesn't already exist there. Diff\nagainst main confirmed to be exactly these three files; go build/vet\nclean; full go test ./... green (internal/dao/postgres, internal/dao/\nsqlite, internal/dao/conformance) against real Postgres 16, real\nCockroachDB v23.2.0, and modernc.org/sqlite.\n\nNote: internal/dao's own TestContractChecksumUpToDate (LT-35's suite,\nunrelated to this package) currently fails on main at fd2505f — the\ncontract A4 amendment changed 05-data-ops/multi-db-strategy.md §1-4\nwithout refreshing that test's expected* transcription/checksum. Not\nintroduced by this branch; flagged separately to the PM rather than\nfixed here since it touches main directly and isn't scoped to LT-38.\n\nStory: LT-38\nWork-By: Renata Cole (lead)\n\nCo-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>\nClaude-Session: https://claude.ai/code/session_011Cuba4JUvrsQCrTdUj4yzk\nEOF\n)\"",

}550 ## 7. The conformance suite — a requirement, not a suggestion 551 552 **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: 553 554 | | What it checks | How | Owner | 555 |---|---|---|---| 556 | **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 | 557 | **Behavioural conformance** (this section) | The backends *behave* alike | One suite of assertions, written once, executed against every backend | 03, at the DAO-behaviour story | 558 559 **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. 560 561 **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. 562 563 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. 564 565 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 — 566 567 - a zero-value `RetentionClass` (`""`) returns `ErrInvalidArgument` — a caller-reachable invalid input, unlike `ErrAlreadyExists`, and therefore owed an explicit assertion rather than only prose; 568 - `maxRows` outside `1..10_000` returns `ErrInvalidArgument`; 569 - `OldestSurvivingAt` is non-nil when rows remain and nothing was old enough to delete, and nil **only** when the class is empty; 570 - `Drained` is false while deletable rows remain at the batch limit and true on the final batch; 571 - every delete writes exactly one `deletion_log` row in the same transaction, with the reason code the *method* asserts; 572 - an already-cancelled context returns before deleting anything; 573 - `deletion_log` carries no PII-shaped column (§6.11); 574 - **deleting a profile actually removes its credentials, asserted on every backend** — the cascade is a governance guarantee (§6.2) whose SQLite enforcement depends on a connection-level pragma that fails silently when absent, so it must be tested rather than assumed. Conversely, deleting a credential must leave its profile standing; 575 - **an invalid `method_id` returns `ErrInvalidMethod` on every backend** — same reason: on SQLite the foreign key does not fire at all without that pragma, so a passing Postgres test proves nothing here. 576 577 --- 578 579 *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.* 580 581 --- 582 583 ## Amendments during implementation 584 585 Every change to this contract after 03 accepted it is logged here with who did the work, per the org attribution rule. The contract is authoritative and the code follows it — an ambiguity found in implementation is answered by amending this document, never by letting the code decide silently. Each entry names the amendment, why it was needed, and the personas who authored, reviewed and objected. 586 587 | # | Date | Section | Change | Why | Work-By | 588 |---|---|---|---|---|---| 589 | A5 | 2026-09-13 | §5, §6.3, §6.9, `migration-approach.md` §2 | Byte-order collation declared per engine by whatever that engine supports; migrations split three ways, one per driver string | `COLLATE "C"` was required on "Postgres/CockroachDB" as though one clause served both. It is **invalid syntax on CockroachDB** (`42601`) — which needs no clause, its default `TEXT` comparison already being byte order — while PostgreSQL needs it explicitly, its default being locale-dependent. No portable clause exists, so the shared `postgres/` migration directory could not express the requirement. **This blocked the CockroachDB conformance run entirely — the migration would not apply.** Ruled to split the migration directories rather than move the guarantee to database-creation locale, keeping the enforcement site visible in the schema instead of in a provisioning step nobody reads | Authored: **Priya Nandakumar**. Surfaced and empirically established by: **Renata Cole** (03) against live CockroachDB v23.2.0, including the test showing its uncollated default already yields the required byte order | 590 | A4 | 2026-09-12 | §3a, §4, §7 | Identifier validation: malformed **or non-canonical** ids return `ErrInvalidArgument`, validated once above the backends against the canonical form only | LT-38's conformance suite found `Get` with a malformed id diverging: Postgres/CockroachDB raise `22P02` before any lookup (`id` is `UUID`-typed), SQLite returns `ErrNotFound` (`id` is `TEXT`). §3a said only that `Get` returns `ErrNotFound`, and §4's "same sentinel for the same condition" did not define what "the same condition" means when column types make a malformed id a different *kind* of failure per engine. Ruled for consistency with every other malformed input in this contract, which already maps to an argument error rather than a data outcome | Authored: **Priya Nandakumar**. Surfaced by: **Renata Cole** (03) via the LT-38 conformance suite — the suite finding a genuine divergence is the per-driver ruling's condition being met. Objection turn: **Yusuf Karadag** (05, Detail Hawk) — **five objections, all accepted; the amendment was substantially revised.** He found that the first version's validator *moved* the divergence rather than closing it (`uuid.Parse` admits four textual forms; Postgres normalizes them and finds the row, SQLite byte-compares and misses), that `""` was undefined, that "every method taking an id" broke three methods and silently changed `ListByUserID`'s guarantee, and that the ruling's stated reason was the weaker one — the decisive argument being that `ErrNotFound` is treated as success by delete callers, so a typo'd subject-deletion request would report completed to the data subject | 591 | A3 | 2026-09-12 | §6.2, §7 | The SQLite enforcement site for the cascade guarantee is the FK **plus a connection-level `foreign_keys` pragma**, set in the DSN; §7 gains cascade and FK-violation assertions | §6.2 named `ON DELETE CASCADE` as the enforcement site, which is true on Postgres/CockroachDB and **false on SQLite**, where foreign keys are off unless enabled per connection. The failure is silent — no error, just a cascade that does not happen — and it would have taken a governance control (§6.2), a retention guarantee (`pii-governance.md`) and an error sentinel (`ErrInvalidMethod`) with it. §7 had no assertion covering any of the three, so no test would have caught it. Found reviewing LT-37 | Authored: **Priya Nandakumar**. Surfaced by: **Renata Cole**'s LT-37 SQLite migration and driver — the defect is in my contract's enforcement site, not in her code, which compensates correctly for today's configuration | 592 | A2 | 2026-09-12 | §7 | Split "conformance" into signature conformance (mechanical, LT-35) and behavioural conformance (the cross-backend suite) | 03 flagged during implementation that the two were being conflated — LT-35's test is signature/type conformance, a different thing from the cross-backend behavioural suite. §7 named only the second while its title implied both, so a signature diff could have been used to tick a requirement it does not satisfy. That would have left the per-driver ruling in `decisions/multi-db-abstraction.md` resting on nothing | Authored: **Priya Nandakumar**. Originated by: **Renata Cole** (03 lead) — the distinction is hers; I only wrote it into the contract. Implementation-side propagation to QA: Renata → Oren Castellan | 593 | A1 | 2026-09-12 | §1a (new) | Package placement, the leaf criterion, and how to read the signatures | LT-35's "byte-for-byte" acceptance criterion is unmeetable as literally stated: 03's layout puts domain structs in `internal/model`, so `*UserProfile` does not compile inside `internal/dao`. Flagged pre-emptively before implementation rather than at review | Authored: **Priya Nandakumar**. Reviewed: **Anders Vogel** — confirmed the ruling, replaced the usage-based placement reason with the leaf/dependency-direction test, closed `ProfileQuery` rather than deferring it, and found both drift paths. No separate objection seat; the review carried the objections | 594 595 **Standing rule for anything landing in git or Jira from this track:** commits are made from a worktree (never a checkout in the shared tree), authored as `Priya Nandakumar (05 Data Ops lead, Claude Opus 5)`, and carry `Story:` and `Work-By:` trailers naming every persona who contributed to that change — author, reviewers, and objection seats alike, not only whoever typed it. 596

}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. 152: Country *string // ISO 3166-1 alpha-2, upper-case 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. 219: Country *string // exact match, alpha-2, upper-cased by the DAO 384:**`ErrInvalidQuery` triggers**, enumerated so 03 does not have to infer them: a non-nil filter that is empty after trimming; `Limit < 0` or `> 100`; `Offset < 0` or `> 10_000`; `Country` not exactly two characters. 394:A secondary consistency argument also holds — every other malformed input here maps to an argument error rather than a data outcome (`Create` with a non-empty `ID`, a two-character `Country`, an out-of-range `Limit`). It is true, and it is *not* load-bearing: both readings cost one translation either way. It is recorded second because that is its actual weight; an objection turn found it had been reached for first. 495:| `requires_secret` | `bool` | BOOLEAN / INTEGER 0-1 | NOT NULL | `false` for passkey/WebAuthn-style methods | 496:| `is_active` | `bool` | BOOLEAN / INTEGER 0-1 | NOT NULL | | 541:5. **`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.* 546:10. **`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. 548:12. **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. 563: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.

"command": "gh pr create --repo wtvamp/loginid-takehome --base main --head feature/LT-38 --title \"LT-38: cross-backend behavioral conformance suite\" --body \"$(cat <<'EOF'\n## Summary\n\nAdds `internal/dao/conformance` — one suite of behavioral assertions, written once against the `dao.Repository` interface, run against all three real backend implementations (Postgres 16, CockroachDB v23.2.0, SQLite via `modernc.org/sqlite`) in a single test binary. Implements `05-data-ops/multi-db-strategy.md` §7 (\"The conformance suite — a requirement, not a suggestion\"): signature conformance (LT-35, already merged, `internal/dao/conformance_test.go`) proves the three packages compile against the same interfaces; this proves they *behave* alike given the same inputs against a live database. §7 is explicit that the first cannot substitute for the second — two implementations can satisfy the same interface and diverge in what they actually return, which is exactly what this phase found three separate times.\n\nThis PR also carries the catch list from the LT-36/LT-37 implementation and review rounds — the defects this conformance suite (or direct testing against real backends) actually found, and what closed each one, since the reasoning behind the suite is as much the deliverable here as the suite itself.\n\n## The catch list\n\nEach item found a genuine cross-backend divergence invisible from reading either implementation in isolation — the exact failure mode §7 says the suite exists to catch.\n\n- **Identifier validation (Amendment A4, §3a/§4/§7)** — `Get` with a malformed id diverged by backend: Postgres/CockroachDB raise `22P02` before any lookup (`id` is `UUID`-typed), SQLite returns `ErrNotFound` (`id` is `TEXT`). Ruled: malformed *or non-canonical* ids return `ErrInvalidArgument`, validated once above the backends against the canonical form only. Went through an objection round (Yusuf Karadag, five objections, all accepted) after the first validator moved the divergence rather than closing it — `uuid.Parse` admits textual forms Postgres normalizes and SQLite byte-compares and misses.\n- **COLLATE \"C\" invalid on CockroachDB (Amendment A5, §5/§6.3/§6.9)** — the shared `postgres/` migration directory's `COLLATE \"C\"` clause is invalid syntax on CockroachDB (`42601`); CockroachDB's default `TEXT` comparison is already byte-order and needs no clause. Blocked the CockroachDB conformance run outright until the migration directories were split three ways, one per driver. Verified directly against live CockroachDB v23.2.0, including the empirical check that its uncollated default already gives the required ordering.\n- **SQLite `foreign_keys` pragma is per-connection (Amendment A3, §6.2/§7)** — `PRAGMA foreign_keys = ON` run once after opening only covered the connection that ran it; the cascade guarantee and `ErrInvalidMethod` FK enforcement silently stopped applying the moment the pool opened a second connection. Fixed via the `_foreign_keys=on` DSN param (applies per-connection by construction), verified by temporarily reverting it and watching `TestIntegration_ProfileDeleteCascadesToCredentials` fail.\n- **`requires_secret`/`is_active` enforcement (§6.10, §6.12)** — neither can be a DDL `CHECK` (one needs `is_active` read from `auth_method`, the other needs `requires_secret` read cross-table); both were missing DAO-layer validation before this round. Now enforced in both backends' `CreateProfileWithCredential`/credential-create paths, each with a conformance assertion.\n- **`Country` write-side normalization (§6.5)** — upper-casing the query without upper-casing the stored value made a stored `us` invisible to a search for `US`. Fixed at write time in both backends' `NormalizeProfileForWrite`.\n- **`DeleteExpired`/`DeleteProfile` TOCTOU (review round, Oren Castellan)** — the original select-then-loop-delete (and select-then-delete) pattern could delete a row that had stopped matching its retention predicate between selection and deletion. Postgres/CockroachDB: collapsed to one CTE-based statement where the `DELETE` re-checks the candidate `SELECT`'s predicate (CockroachDB additionally requires `RETURNING` on every write CTE, or it rejects the statement as returning no columns). SQLite: re-adds the predicate to the per-row `DELETE` directly, since SQLite has no writable-CTE support (confirmed by testing DML inside `WITH` directly: `SQL logic error: near DELETE: syntax error`) — same fix intent, backend-appropriate mechanism.\n- **No backoff on CockroachDB retry (review round, Nolan Reyes)** — `retryLoop` retried a `40001` serialization failure in a tight spin loop; added jittered backoff between attempts, with a test confirming a cancelled context aborts the wait rather than blocking for its full duration.\n- **Nil-vs-empty-slice JSON serialization (review round, Oren Castellan)** — `Search`/`ListByUserID`/`List` returned a nil slice on zero results, serializing to `null` instead of `[]`; fixed in both backends.\n\n## What's in this diff specifically\n\nOnly `internal/dao/conformance/{conformance_test.go, helpers_test.go, testutil_test.go}` — everything else the catch list above touches (the DAO code itself, the split migrations, the id-validation/normalization fixes) is already on `main` via PR #6 (LT-36) and PR #8 (LT-37), including their review-round fixes. This branch's own commit history had replayed pre-rebase copies of those two branches and produced spurious whole-file conflicts against their final merged versions on `main`; rather than force a rebase through that, this PR resets cleanly onto `main` and re-adds the one piece that doesn't already exist there.\n\nThe suite covers, per backend: `errors.Is` sentinel parity for every `dao.Err*` (including the id-validation and duplicate-username/invalid-method/invalid-query/invalid-argument/invalid-credential cases), `requires_secret`/`is_active` enforcement, cascade-delete and no-cascade-on-credential-delete semantics, `DeleteExpired` (invalid class, `maxRows` bounds, `OldestSurvivingAt` nil-vs-non-nil, `Drained`), exactly-one `deletion_log` row per delete, an already-cancelled-context deletes-nothing check, and `TestConformance_CockroachDB_RealSerializationRetry` — which forces a genuine `40001` against live CockroachDB rather than a mocked error, so the retry path is proven end-to-end and not just against `retry_test.go`'s `fakeErr()`.\n\n## Verification\n\n- `go build ./...` / `go vet ./...` clean.\n- `go test ./...` green against real Postgres 16 (`postgres:16-alpine`), real CockroachDB v23.2.0 (`cockroachdb/cockroach:v23.2.0`), and `modernc.org/sqlite` — `internal/dao/postgres`, `internal/dao/sqlite`, `internal/dao/conformance` all pass.\n- Note: `internal/dao`'s `TestContractChecksumUpToDate` (LT-35's suite, unrelated to this package) currently fails on `main` at `fd2505f` — the contract A4 amendment changed `05-data-ops/multi-db-strategy.md` §1–§4 without refreshing that test's transcribed `expected*`/checksum. Not introduced by this branch; flagged separately to the PM since fixing it means editing a file already on `main`, out of scope for this PR.\n\n## Who did the work\n\n- **Renata Cole** (03 Engineering & Delivery, lead) — suite design and implementation, all fixes in the catch list above, empirical verification against live Postgres/CockroachDB/SQLite.\n- **Oren Castellan** (03, QA/Detail Hawk) — review flagging the TOCTOU pattern and the nil-slice serialization issue on both PR #6 and PR #8.\n- **Nolan Reyes** (03, ops/failure-mode reviewer) — review flagging the missing retry backoff and the `MaxOpenConns(1)` pool-queue contention scope note.\n- **Priya Nandakumar** (05 Data Ops, lead) — authored Amendments A3/A4/A5 and the §7 conformance requirement this suite implements.\n- **Yusuf Karadag** (05, Detail Hawk) — objection turn on Amendment A4 (five objections, all accepted).\n- Model: Claude Sonnet 5, via Claude Code, orchestrated per `02-ai-security-architecture/planning-approach.md`.\n\n🤖 Generated with [Claude Code](https://claude.com/claude-code)\n\nhttps://claude.ai/code/session_011Cuba4JUvrsQCrTdUj4yzk\nEOF\n)\"",

"message": "1. LT-38: PR #16 is open (https://github.com/wtvamp/loginid-takehome/pull/16), title \"LT-38: cross-backend behavioral conformance suite\", base main, head feature/LT-38.\n\nRebasing hit a real problem worth flagging: feature/LT-38's own history had merged old, pre-rebase copies of LT-36/LT-37 (from before they went through their own review-round rebases), so a straight `git rebase origin/main` produced spurious whole-file add/add conflicts replaying commits that no longer matched what's actually on main. Rather than force that through, I diffed feature/LT-38 against main directly and confirmed the *only* real unique content left was internal/dao/conformance/ (three files) — everything else (DAO code, split migrations, id-validation/normalization fixes) was already on main via #6/#8. So I reset feature/LT-38 onto main and re-added just that package, force-pushed, verified build/vet clean and go test ./... green against real Postgres 16, real CockroachDB v23.2.0, and SQLite (including internal/dao/conformance and TestConformance_CockroachDB_RealSerializationRetry against a live 40001).\n\nThe PR description carries the full catch list you asked for — requires_secret/is_active (§6.10/§6.12), Country normalization (§6.5), Amendment A4 (id validation) and A5 (COLLATE split) with the actual contract citations, plus the TOCTOU/backoff/nil-slice review-round fixes — and a \"Who did the work\" section.\n\nOne thing surfaced while testing that's not mine to fix: `internal/dao`'s `TestContractChecksumUpToDate` (LT-35's signature-conformance suite) is currently RED on main at fd2505f — contract Amendment A4 changed multi-db-strategy.md §1-4 without refreshing that test's transcribed expected*/checksum. Confirmed it fails on main independent of anything in my branch. Someone needs to re-read the current §1-4 and update internal/dao/conformance_test.go's expected* declarations and expectedContractChecksum — flagging to you since it's a file already on main, not scoped to a feature branch.\n\n2. buildinfo.go: confirmed and sent directly to Theo (04-infra-devops-47) — the exact ldflags is `-X loginid-takehome/internal/app.Commit=$GIT_SHA` (package internal/app, var Commit, module loginid-takehome). No code change needed on my side; already exists on main as-is with a test asserting the field is non-empty.",

}1 # LT-32 refinement — split the token issuer into its own Deployment with isolated signing-key custody 2 3 **Product Owner:** Naomi Voss (01). **Research team:** Imogen Hale, Desmond Okafor, Tobias Lindqvist. **Engineering:** Renata Cole (03, `APP_MODE` binary support), Theo Bergman (04, manifest/Deployment split); design owner Marcus Ilori (02, `handoff-04-secrets.md`/F13). **Source:** `02-ai-security-architecture/backlog.md` S12 (LT-32). 4 5 **Who did the work:** Refined by Naomi Voss (PO); claims check Desmond Okafor; objection Tobias Lindqvist; engineering counterparts Renata Cole and Theo Bergman. 6 7 ## Why this one, not LT-39, and why now 8 9 Checked the actual dependency chain rather than assuming: `backlog.md` S7 (auth middleware, LT-40) lists "04: `APP_MODE` Deployment split" as a hard dependency — that's this story. S6 (the search/retrieve handlers, LT-39) doesn't list LT-32 or S7 as a formal dependency (it can be built and merged against fakes without either), but a handler that calls `authorize()` on claims nothing has yet populated isn't a **reviewable, working endpoint** — it's code that compiles and can't be correctly exercised end-to-end at the public URL. LT-32 is the actual bottleneck: nothing downstream (S7, and a genuinely working authenticated S6) can be truly deployed and reviewed without it. Confirmed by checking the live manifest directly (`deploy/manifests.yaml` on `main` as of this refinement): no `api-service-issuer` Deployment exists, no JWT signing-key mount — this story hasn't landed in any form yet, it isn't partially done. 10 11 Per Jira's own resolved ambiguity (`LOG.md`: "LT-34 blocks LT-32"), LT-32 was gated on LT-34 landing — LT-34 is now implemented and deployed (review pending only on the build-SHA fix, unrelated to this story), so LT-32 is unblocked and ready to pull. 12 13 ## What this story actually is, restated plainly 14 15 Not a new binary, not new business logic — a **Deployment-topology fix** closing a real security gap the consistency pass found (F13): `handoff-04-secrets.md` said the signing key "never touches `api-service`" while the manifest mounted it into every replica of one `api-service` Deployment. RBAC on a `Secret`'s `get` verb does nothing once the volume is already mounted into a running container — so the only real fix is a second Deployment of the same image, selected by `APP_MODE=issuer` vs. the default, with its own ServiceAccount that alone can mount the key. 16 17 ## Acceptance outcome (no new public-URL behavior yet, but it's the load-bearing gate before any is trustworthy) 18 19 This story doesn't add a caller-visible endpoint — `/healthz` still looks the same. "Done" is verified by manifest inspection and a runtime check that the two Deployments' pods genuinely differ in what they can mount, not by curling something new. 20 21 ## Acceptance criteria (restated from `backlog.md` S12) 22 23 - [ ] `api-service` (the Go binary) supports an `APP_MODE` environment variable selecting issuer vs. default (verifying) behavior from one binary/image — no second `cmd/` entrypoint, per `handoff-04-secrets.md`'s explicit "not a third binary" ruling. Enforcement site: `internal/config` reads `APP_MODE`, `internal/app` branches on it at startup. 24 - [ ] Two Kubernetes Deployments exist in the manifest (`api-service` and `api-service-issuer`), each with its own ServiceAccount. Enforcement site: `deploy/manifests.yaml`, two distinct `Deployment` objects. 25 - [ ] Only `api-service-issuer`'s pod spec mounts the JWT signing-key `Secret` — **physically absent, not just RBAC-denied, from `api-service`'s pod spec.** Enforcement site: manifest inspection of `api-service`'s volumes/volumeMounts list, which must contain no reference to that `Secret` at all — a reviewer checking RBAC alone would miss a mistakenly-shared mount, per F13's own finding that RBAC doesn't prevent this class of leak. 26 - [ ] RBAC (`Role`/`RoleBinding`) additionally restricts `get`/`list` on the signing-key `Secret` to `api-service-issuer`'s ServiceAccount specifically — a second, independent layer on top of the physical-absence criterion above, not a substitute for it. 27 - [ ] The `api-service` (verifying) Deployment holds only the public key material needed to verify, never the private key, regardless of `APP_MODE`'s runtime value — enforcement site: a startup-time check/test asserting the verifying binary's process has no path to the private key even if `APP_MODE` were misconfigured to `issuer` on that Deployment (defense against a manifest typo, not just a design intent). 28 - [ ] `containerization-design.md`'s single-Deployment mount (the line the consistency pass named) is removed from the design doc and replaced with the two-Deployment description, so a future reader of the design doc sees the corrected shape, not the superseded one. 29 - [ ] The issuer Deployment's public route (whatever path 02/03 finalize for token issuance — e.g. `/auth/token`) is added to the `Ingress`, routed to `api-service-issuer`, distinct from `api-service`'s existing routes; `idp-connector` remains unrouted, unaffected by this change. 30 - [ ] **Added per Tobias's objection:** the JWT signing-key `Secret` is excluded from the CI-applied manifest set that the scoped deploy runner (LT-45/LT-47) manages — either provisioned/rotated out-of-band (e.g. a one-time `kubectl create secret` by whoever holds cluster admin, or a dedicated secrets step outside the general `apply` pass), or, if it must be in the applied manifest set, explicitly excluded from the runner's RBAC `resourceNames` for `Secret` gets. Without this, the runner's necessarily-broad `Secret` access for ordinary application config (granted in `deploy-path.md` §2 so `kubectl apply` can diff against live state) would give the CI runner's ServiceAccount read access to the signing key regardless of how tightly this story scopes the issuer's own RBAC — a second, unexamined path to the same secret that criteria 3–4 above don't check for because they only look at the issuer Deployment's own boundary, not the deploy pipeline's. 31 32 ## Non-goals 33 34 - No change to the JWT scheme itself (claims, TTL, `kid` rotation mechanics) — that's `api-auth-design.md`'s design and S7's (LT-40) implementation, not this story's. 35 - No auth middleware implementation (JWT verification, rate limiting) — that's S7 (LT-40), which depends on this story but is a separate pull. 36 - No handler-layer `authorize()` logic — that's S6 (LT-39), also downstream of this and S7. 37 - No change to `idp-connector` — it has no issuer/verifier split; this story only touches `api-service`. 38 39 ## PO review script 40 41 1. Confirm `deploy/manifests.yaml` (or wherever the PR puts it) has two distinct `Deployment` objects for the `api-service` image, each with its own `ServiceAccount`. 42 2. Read `api-service-issuer`'s pod spec: confirm the signing-key `Secret` volume mount is present. 43 3. Read `api-service`'s (verifying) pod spec: confirm **no** reference to that `Secret` anywhere — no volume, no volumeMount, not even an unused one. 44 4. Read the `Role`/`RoleBinding` scoping `get`/`list` on the `Secret` to the issuer's ServiceAccount specifically, not both. 45 5. Confirm `containerization-design.md` no longer describes the single-Deployment mount the consistency pass flagged. 46 6. Once deployed: hit the issuer's route (once 02/03 finalize its path) and confirm it's reachable and distinct from `api-service`'s existing routes; confirm `idp-connector` is unaffected (still unrouted). 47 7. If feasible, a deliberate negative check: attempt (from outside, with no special access) to read the signing-key `Secret` via the verifying Deployment's own ServiceAccount token — should fail, confirming criteria 3+4 together, not just one or the other. 48 8. **Added per Tobias's objection:** read the scoped CI deploy runner's `Role`/`RoleBinding` (LT-45/LT-47) and confirm the signing-key `Secret`'s name is either absent from its `resourceNames` list, or the `Secret` is never part of the manifest set that runner applies at all — the same negative-check discipline as step 7, extended to the one ServiceAccount the issuer-boundary criteria don't examine. 49 50 ## Research team review 51 52 **Desmond Okafor — claims check:** Independently verified the dependency-chain reasoning (S7's "Depends on" line names LT-32 by F13 tag), the "LT-34 blocks LT-32" citation (verbatim in `LOG.md`), the F13 quote/mechanism, and the "physically absent, not just RBAC-denied" framing — all confirmed accurate against the source documents, no invented detail, no overreach. No corrections needed. 53 54 **Tobias Lindqvist — objection:** This story locks down the issuer Deployment's own boundary (physical mount absence + scoped RBAC) but never checks the *other* ServiceAccount with broad `Secret` access in the namespace — the scoped CI deploy runner from his own earlier LT-45/LT-47 review, which needs `get`/`list` on `Secrets`-by-name to `kubectl apply` and diff against live state. If the signing-key `Secret` is part of what the runner applies, its ServiceAccount can already read the private key regardless of how tightly this story scopes the issuer's own RBAC — a second, unexamined path to the same secret, found by cross-referencing two separately-reviewed documents rather than either one in isolation. Counter-proposal accepted: added a criterion requiring the signing-key `Secret` be provisioned out-of-band from the CI-applied manifest set, or explicitly excluded from the runner's RBAC `resourceNames`, plus a matching PO-script step. 55 56 **Naomi Voss — ruling:** Fix applied. This refinement is accepted and ready to hand off. This is the strongest catch across every refinement this pass — not a citation error or an ambiguous wording, but a genuine, previously-invisible privilege-escalation path that only became visible by checking this story against a sibling refinement's own conclusions. Exactly what having a standing research team is for. 57

No flags, no config files. - **DAO driver-selection mechanism:** a factory `dao.New(driver, dsn string) (dao.Repository, error)` chosen at startup from `DB_DRIVER`. `dao.Repository` is a composite interface — `Profiles() ProfileRepository`, `Credentials() CredentialRepository`, `Methods() AuthMethodRepository`, plus `CreateProfileWithCredential(ctx, p, c)`, `DeleteExpired(ctx, class, olderThan, maxRows)`, `DeleteProfile(ctx, id, externalRef)`, and `Close() error` directly on the composite — matching 05's now-accepted contract in `multi-db-strategy.md` §1/§3b/§3c (the retention-sweep addendum, consistency-pass F21), kept deliberately distinct (not one flat interface) because it's a load-bearing PII/credential-separation control per `05-data-ops/pii-governance.md`: a handler has to reach for the credential accessor on purpose. Each backend package returns one struct satisfying the composite. Factory signature and `DB_DRIVER` selection are unchanged. - **Stable for 04 to build against:** the two-binary split, the `cmd/` entrypoint names, the env-var config approach and variable names above, and the `dao.New(driver, dsn)` factory signature. **05's contract has landed and is accepted** (consistency-pass F23 — this line previously said the composite's method set was "not yet stable" pending the contract; it has since landed, including `CreateProfileWithCredential` and `Close()` above). **Not yet stable:** internal DAO implementation details, ORM/query-builder choice, handler-package internals — those are implementation, not contract. - **Note for 04, from the Go-layout three-hats ruling (`03-engineering-delivery/decisions/go-layout-debate.md`):** "two binaries" is a *process* boundary, not a claim about host/deploy placement — whether `api-service` and `idp-connector` land on the same node is 04's call, not implied by this section. If they're colocated, `idp-connector`'s outbound-call failure isolation from `api-service` depends on 04's resource limits, not just the process split. Separately, S4 now requires `context.WithTimeout` on every outbound vendor call and a bounded connection pool/backoff on token-refresh retries — not a 04 concern, but flagged here so 04 doesn't assume connector-side backpressure is handled elsewhere. ## Dependency order (from `planning-approach.md` §2) 1. First wave, in parallel: 01, 02, 05 — 05 is on the critical path (it hard-blocks 03's DAO and partially blocks 04). 2. 03 split start: scaffolding may begin immediately; DAO once 05's Go-shaped contract is stable; middleware once 02's receiver-shaped auth hand-off lands. 3. 04 last, gated on the three inputs named in its row.

5 // decisions/test-double-strategy.md. Asserts that this package's exported

7 // composite, domain types, sub-interfaces plus ProfileQuery, and sentinels)
8 // byte-for-byte, not "close enough".
9 //
10 // MECHANISM: FROZEN COPY, not live-parse. Reliably extracting exact Go
11 // signatures out of markdown prose is impractical — multi-db-strategy.md is
12 // prose describing Go shapes inside fenced code blocks, not a Go source
13 // file a parser can trust. Instead, the "expected*" declarations below were
14 // transcribed by hand from §1–§4 at the time this test was written, and
15 // pinned two independent ways so a drift on either side is caught:
16 //
17 // 1. Structural, on OUR side: assertInterfaceEquivalent checks the actual
18 // dao interfaces against the hand-transcribed expected* interfaces by
19 // mutual reflect.Type.AssignableTo (same method set, both directions)
20 // plus a method-count check, which catches an added, removed, or
21 // resignatured method that "compiles fine" checks alone would miss.
22 // assertStructFields does the same for domain/query/result structs,
23 // field by field, in order. The factory signature (§1) is pinned by a
24 // compile-time function-variable assignment — a mismatch fails the
25 // build, not just this test. Sentinel identity (§4) is checked by
26 // exact wrapped-message string equality, and sentinel-SET completeness
27 // (nothing added or removed without updating this test) is checked by
28 // parsing this package's own errors.go with go/parser — a syntax parse
29 // of our own Go source, not of the markdown, so it doesn't fall under
30 // the "impractical" case above.
31 //
32 // 2. Drift, on the DOC's side: TestContractChecksumUpToDate hashes
33 // 05-data-ops/multi-db-strategy.md's §1–§4 section (delimited by the
34 // marker strings below, matching this file's own scope) and compares
35 // it against expectedContractChecksum, frozen at transcription time.
36 // If 05 revises that section, this test FAILS LOUDLY instead of
37 // silently continuing to assert a stale copy of the contract — a human
38 // must re-transcribe the expected* declarations below and refresh the
39 // checksum constant, not just bump a version number.
40 //
41 // Known scope limit, stated rather than hidden: this test proves the Go
42 // shapes named in §1–§4 match what was transcribed from the doc at the time
43 // of transcription, and that the doc section hasn't since changed
44 // underneath that transcription. It cannot prove the original transcription
45 // itself was faithful — that's why the PO review script
46 // (refinement/LT-35.md) has a human diff the PR against the doc directly,
47 // rather than trusting this test's own claim of a match.

}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:
245
246 - `Create` — insert. `ErrAlreadyExists` if the ID is taken.
247 - `Update` — update an existing row by ID. **`ErrNotFound` if the row does not exist.** It never creates.
248 - `Upsert` — the portable `INSERT ... ON CONFLICT (id) DO UPDATE` form. For a caller that **already holds the `id`** and does not know whether the row is still present — re-hydrating a known profile. Any other caller uses `Create` or `Update`. (This bullet previously justified `Upsert` by the IDP hydration path, a justification retracted three paragraphs below and left standing here; caught in the same sweep as F20.)
249
250 **`Update` and `Upsert` are FULL REPLACEMENTS, not partial patches.** This is the single most consequential thing in this document and it was missing from the first draft. Every column is written from the struct you pass. **A nil `Phone` sets the stored phone to NULL; it does not leave the existing value alone.** A caller wanting patch semantics must read, modify, and write back. Stated this loudly because both readings are reasonable and the wrong guess silently destroys data.
251
252 **`Upsert` conflicts on `id` only, and the caller must already hold that `id`.** It exists for re-hydrating a row already known to exist — not for resolving an unknown one. A cold read caught the circularity in the original justification: the IDP path "does not know whether the row exists" and therefore does not know its `id` either, so `Upsert` could not have served the caller it was justified with. **Resolving an `/identity` payload to an existing profile row is not the DAO's problem** — there is deliberately no unique key on `phone` or `name` to match on, because neither is unique in reality. It belongs to **`api-service`**, which is the party that both decides identity and holds a DAO handle: 03's layout gives `idp-connector` no database access at all (`../03-engineering-delivery/decisions/go-layout-debate.md`), so the connector fetches the payload and its caller decides what the payload *is* and then calls `Create` or `Update`. An earlier version of this sentence said "the connector" and was wrong about which process can reach the database (finding F22).
253
254 **`Delete` on a missing row returns `ErrNotFound`**, in both repositories — not a silent nil. Consistent with `Update`. Callers wanting idempotent delete check `errors.Is(err, ErrNotFound)` and treat it as success.
255
256 **`GetByUsername` lower-cases its input inside the DAO.** Callers pass whatever the user typed. This matches the `UNIQUE (lower(username))` index in §5; requiring callers to fold case themselves would put the guarantee outside its enforcement site.
257
258 `Context` is first on every method and cancellation is honoured. **No method holds a transaction across calls.** If the service layer needs a multi-statement transaction, that is a change to this contract — flag it to 05 rather than improvising a `Begin`/`Commit` pair inside 03.
259
260 **`Delete` on a profile cascades to its credentials — see §6.2 before calling it.** Pointer placed here deliberately: a cold read found the surprise arriving ~140 lines before the explanation.
261
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

359 Every backend returns the same sentinel for the same condition; the service layer never distinguishes `sql.ErrNoRows` from a SQLite-specific miss. Test with `errors.Is`. Anything not in this set is wrapped with `%w` and passed through.
360
361 ### How driver errors become sentinels
362
363 The first draft said "translation is by SQLSTATE code only — never by matching error message text or constraint names." A cold read found that rule both **self-contradicting** (`23505` alone cannot say *which* column collided, yet the same paragraph asked for different sentinels per column) and **unimplementable on half the codebase** (SQLite has no SQLSTATE at all). Both were right. The revised rule:
364
365 **Match on structured error codes, plus constraint names that we ourselves define in our own DDL. Never parse free-text error messages.**
366
367 - *Postgres / CockroachDB*: match SQLSTATE, then disambiguate within it by the constraint name the error carries.
368 - *SQLite*: match the extended result code (`SQLITE_CONSTRAINT_UNIQUE`, `SQLITE_CONSTRAINT_FOREIGNKEY`, `SQLITE_CONSTRAINT_CHECK`), then disambiguate by the same constraint name.
369
370 Constraint names are pinned **because they are our artifact, not the engine's**: we write them in our own migrations, so they are stable across engines and versions in a way an engine-generated message is not. That is the distinction the original rule was reaching for and stated wrongly. Every constraint in §5 is explicitly named in DDL for this reason; an unnamed constraint is a translation failure waiting to happen.
371
372 | Condition | PG / CRDB | SQLite | Sentinel |
373 |---|---|---|---|
374 | duplicate username | `23505` on `uq_user_credential_username` | `SQLITE_CONSTRAINT_UNIQUE`, same name | `ErrDuplicateUsername` |
375 | duplicate id | `23505` on a PK constraint | `SQLITE_CONSTRAINT_PRIMARYKEY` | `ErrAlreadyExists` |
376 | unknown `method_id` | `23503` on `fk_user_credential_method` | `SQLITE_CONSTRAINT_FOREIGNKEY` | `ErrInvalidMethod` |
377 | any CHECK violation (`source`, `name`, `phone`, `country`, address non-empty) | `23514` | `SQLITE_CONSTRAINT_CHECK` | `ErrInvalidArgument` |
378 | secret-state CHECK | `23514` on `ck_user_credential_secret_state` | same, same name | `ErrInvalidCredential` |
379
380 **`ErrInvalidArgument` closes a real hole**: the commonest caller mistake is a write that violates a CHECK constraint, and in the first draft that arrived at the service layer as a raw, engine-specific driver error. `ErrInvalidQuery` protected reads and nothing protected writes.
381
382 `research-cockroachdb-postgres-semantics.md` §3 records that CockroachDB has a documented history of SQLSTATE inconsistency on constraint errors and that message/`DETAIL` structure is not portable — so pin the CockroachDB target version, and treat any message-text matching found in review as a defect.
383
384 **`ErrInvalidQuery` triggers**, enumerated so 03 does not have to infer them: a non-nil filter that is empty after trimming; `Limit < 0` or `> 100`; `Offset < 0` or `> 10_000`; `Country` not exactly two characters.
385
386 ### Identifier validation — `ErrInvalidArgument`, canonical form only (amendment A4, revised)
387
388 A syntactically invalid `id` behaves differently per backend and the contract did not say what it should mean. Postgres/CockroachDB type `id` as `UUID`, so the driver raises `22P02` *before any row lookup*; SQLite types it as `TEXT`, so the same string is an ordinary lookup that finds nothing. Found by LT-38's conformance suite.
389
390 **Ruling: a malformed or non-canonical identifier is `ErrInvalidArgument`, never `ErrNotFound`.**
391
392 **The decisive reason is governance, not symmetry.** This contract tells callers to treat `ErrNotFound` from a delete as success (§3, idempotent delete). So under the alternative reading — malformed id means "not found" — **a subject-deletion request with a typo'd identifier reports *completed* to the data subject.** A GDPR erasure request would be recorded as performed while nothing was deleted, and `pii-governance.md` builds the whole subject-deletion path on this sentinel. That is the argument that decides it.
393
394 A secondary consistency argument also holds — every other malformed input here maps to an argument error rather than a data outcome (`Create` with a non-empty `ID`, a two-character `Country`, an out-of-range `Limit`). It is true, and it is *not* load-bearing: both readings cost one translation either way. It is recorded second because that is its actual weight; an objection turn found it had been reached for first.
395
396 #### Canonical form only — the validator must not admit variants
397
398 **`uuid.Parse` is too permissive to use as the validator**, and using it would move this defect rather than close it. It accepts the canonical form, brace-wrapped, `urn:uuid:`-prefixed and unhyphenated hex, case-insensitively. All four would pass validation — and then **Postgres normalizes them and finds the row, while SQLite byte-compares `TEXT` against the stored canonical form and returns `ErrNotFound`.** An uppercase-hex UUID is the cheapest reproduction. The divergence simply relocates from malformed identifiers to well-formed non-canonical ones, where no assertion was looking.
399
400 So: **the validator accepts only the canonical 36-character lowercase hyphenated form and rejects the other three.** Correspondingly, **every write path stores exactly that form** — on SQLite this is a requirement, not a convention, because `TEXT` comparison is byte-wise and there is nothing else to enforce it.
401
402 **The empty string is `ErrInvalidArgument` on every lookup.** It is the commonest caller bug — a zero-value struct field — and had no stated answer. `Create`'s `ID` is the single named exception, where `""` is *required*.
403
404 #### Where validation applies — named parameters, not "every id"
405
406 A blanket rule breaks three methods, so the rule names its parameters:
407
408 **Validated:** `Profiles().Get`/`Update`/`Upsert`/`Delete` `id`; `Credentials().Update`/`Delete` `id`; `Credentials().ListByUserID` `userID`; `Methods().Get` `id`; `DeleteProfile` `id`.
409
410 **Not validated:** `Create`'s `ID` (must be `""`); `CreateProfileWithCredential`'s `c.UserID` (ignored on input and overwritten); `DeleteProfile`'s `externalRef` (an opaque external reference, not a UUID); `GetByUsername`'s `username` and `Methods().GetByName`'s `name` (not identifiers).
411
412 **One guarantee changes as a result, and it is recorded rather than absorbed:** `ListByUserID` is documented to return an empty slice rather than `ErrNotFound` when a user has no credentials. It now returns **`ErrInvalidArgument`** on a malformed `userID` — a different outcome from both, and §3a's row is updated to say so.
413
414 #### Enforcement site
415
416 **One validator in shared DAO code above both backends**, not two per-backend error translations that must agree. Parity is then by construction: Postgres never reaches the query, SQLite never silently misses. `22P02 → ErrInvalidArgument` stays in the backend translation as a **backstop** for any path where a malformed identifier reaches SQL another way — defence in depth, not the enforcement site.
417
418 #### Conformance assertions (§7) — three, not two
419
420 1. A malformed identifier returns `ErrInvalidArgument` on every backend.
421 2. A **well-formed canonical** identifier naming no row returns `ErrNotFound` on every backend.
422 3. A **well-formed non-canonical** identifier (uppercase hex, braced, `urn:uuid:`, unhyphenated) returns the same result on every backend.
423
424 The first two together prove the distinction is syntactic rather than existential. **The third is what tests the defect this amendment was revised to fix** — without it, the uppercase-hex divergence is untested and A4 would have shipped its own bug.
425
426 ### The write-path retry seam — a decision, not an observation
427
428 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.
429
430 **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.
431
432 `Search` is read-only, two independent statements, no explicit transaction — it never encounters `40001` and needs no wrapper.
433
434 **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:
435
436 - 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.
437 - 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.
438 - 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.

---handoff-04-secrets---
1:# Hand-off 02 → 04: Secrets inventory and never-log list
3:Status: **v2** — v1's S7 objection turn and 04's Newcomer cold read are both resolved and folded in below; this revision additionally resolves four findings from the cross-track consistency pass (F12 this version label, F13 the signing-key custody contradiction, F15 a missing credential row, F50 two never-log gaps). Receiver: Theo Bergman, `../04-infra-devops/`. Written to the project's hand-off standard: 04 should be able to act on this without re-deriving the reasoning in `threat-model.md`, `api-auth-design.md`, or `connector-security.md`.
7:1. Deployment target is 04's **real Kubernetes cluster, reachable via a plain nginx Ingress + cert-manager on the cluster's shared LoadBalancer** (DNS CNAME to `uplifttech.ddns.net`, public at `https://loginid-takehome.uplifttech.org` — no tunnel; Warren's implementation go-ahead, 2026-09-12, updated from a design-only reference). Delivery mechanism is therefore Kubernetes-native `Secret` objects unless 04 chooses an external store; every requirement below is written so it still holds if the mechanism changes. **The repository is now public** (`https://github.com/wtvamp/loginid-takehome`) — every requirement in this document that says "never in source or committed config" is now categorical, with no private-repo safety net.
8:2. Service topology is 03's published boundary (`../PLANNING.md`, Service boundaries): two binaries, `cmd/api-service` (Q1 DAO + Q2 REST API) and `cmd/idp-connector` (Q3), env-var configuration only. Variable names below are 03's; two are marked as pending this track's final scheme. **The token-issuing authorization-server function is a mode of `api-service`, not a third binary** — this take-home's scope doesn't justify a standalone authz server, and 03 has published no third `cmd/` entrypoint. **Corrected by the cross-track consistency pass (F13):** "a mode of the same binary" is not "the same Kubernetes Deployment," and the earlier text here was wrong to imply RBAC alone separates them — a Kubernetes Role restricting `get` on a Secret has no effect on a volume already mounted into a container, so if `api-service`'s one Deployment mounted the signing key, every replica (verification path included) would have it on disk regardless of RBAC. **The fix: the issuer runs as a second Deployment of the same `api-service` image**, selected by an environment variable 03 adds to the config surface (e.g. `APP_MODE=issuer` vs. the default, consistent with the surface's env-var-only, no-flags rule), with **its own ServiceAccount that alone mounts the signing-key Secret** (row #2) — the `api-service` Deployment serving verification/search mounts nothing from row #2. This is a request into 03's Deployment/mode surface, not a unilateral change on my part; flag to me if the mode-selection mechanism needs to differ.
9:3. An **external operator agent** — a human or automated actor outside this project, holding cluster-admin or namespace-admin rights on 04's real lab cluster, who applies Kubernetes manifests to it — is a privileged actor outside this service: anyone who can apply a manifest can read any Secret it mounts. Consequence for 04: manifests reference Secrets by name and never carry values; values are set out-of-band. This is a named trust boundary in `threat-model.md` Assumption 7, not a silent assumption; nothing further about who that operator is needs to be re-derived from 04's own files to act on this hand-off. As of this update, 04 has not yet made contact with that operator or deployed anything — `threat-model.md` carries the dated status.
12:## Secrets inventory
14:| # | Secret | Used by | Injection requirement (02 sets it) | Rotation expectation | Kubernetes-native note (04's mechanism) | Never-log |
16:| 1 | Database credentials, carried inside `DB_DSN` | `api-service` | Runtime-injected; never in source, image, or committed config. **Required, not preferred: file mount via a `DB_DSN_FILE` convention** (03 to add alongside `DB_DSN`), because a DSN's embedded password is exposed by `kubectl describe`, crash dumps, and child-process environment exactly as much as any other secret in this table — there is no citation that makes `DB_DSN` a lesser case, so this track is not treating it as one | On credential rotation; service restart or reload acceptable | `Secret` mounted read-only as a file, read via `DB_DSN_FILE`; env-var `DB_DSN` is a fallback only until 03 ships the file-based convention, not a permanent equal option | Yes — the DSN contains the password; log the driver name and host at most |
17:| 2 | JWT signing **private** key (RS256/ES256), per `api-auth-design.md` | The issuer Deployment (`api-service` image, `APP_MODE=issuer`) only — **not** the `api-service` Deployment that verifies with the public key; these are two Deployments of one image, not one Deployment doing both (F13 fix) | Runtime-injected as a **file**, never an env var; asymmetric so the verifying Deployment never holds it | Key rotation with a `kid` claim; publish old and new public keys together during overlap; TTL of tokens (5–15 min) bounds the overlap window | `Secret` mounted read-only as a file, **only into the issuer Deployment's pod spec** (not the verifying Deployment's); RBAC restricts `get`/`list` to the issuer's own ServiceAccount | Yes |
19:| 4 | API caller `client_secret`s (OAuth2 client-credentials) | Authorization server (verifies); callers hold their own copy | **Stored hashed** (Argon2id, same floor as `threat-model.md` Asset 1), never plaintext at rest; issued once at provisioning and not recoverable | Per-client rotation on demand; revoke by deleting the hash | Lives in the issuer's datastore, not a Kubernetes `Secret`; 04 delivers only that datastore's credentials (#1-shaped) | Yes |
20:| 5 | Connector's own vendor registration: `IDP_ABC_CLIENT_ID`, `IDP_ABC_CLIENT_SECRET` (and the XYZ pair if a second vendor is configured) | `idp-connector` | Runtime-injected; never in source or committed config; `client_id` is low-sensitivity but travels with the secret and gets the same handling | Per vendor's policy; expect manual rotation | One `Secret` per vendor so rotating ABC never touches XYZ; file mount preferred | Yes for the secret; keep the id out of logs too |
21:| 6 | Vendor `access_token` (returned by our own `/auth` to its authenticated caller, presented as a header on our own `/identity` — updated for F3's caller-holds-the-token model, seam re-run regression fix) | `api-service` holds it briefly between the two calls; `idp-connector` only ever sees it as a caller-presented header on a single `/identity` request, never fetches or holds it between calls itself | **Not a deployed secret** — transient on both sides, never cached, never persisted. Neither `api-service` nor `idp-connector` writes it to a datastore (S3's no-cache ruling, restated for the two-party model in `connector-security.md` §1) | Expires on its own; never persisted across restarts by either party | No `Secret` object anywhere in this flow — there is nothing here for 04 to provision | Yes — never, including error paths, on both sides of the exchange |
22:| 7 | Data-encryption key (KEK) for envelope encryption of any TOTP shared secrets | `api-service` (TOTP) only — **not a committed feature of this submission**; `user_credential.method` is modeled as an extensible lookup table (`../05-data-ops/multi-db-strategy.md`) that supports TOTP as a *possible* value, but no TOTP implementation is planned unless 03 builds one. **The vendor-token-cache use case for this row no longer exists**: S3's red/blue on the connector token lifecycle is closed (`decisions/connector-token-lifecycle-redblue.md`) — no cache by default, and the token is never held by the connector between calls at all under F3's model (row 6), so there is no vendor-token cache for a KEK to encrypt. This row is provisioned only if TOTP materializes — it is a contingency the inventory names in advance, not a live requirement for 04 to build now | Runtime-injected as a file; the KEK never leaves the process that decrypts | Rotation by re-wrapping DEKs; never requires re-hashing passwords (those are hashed, not encrypted) | `Secret` (file mount) or an external KMS if 04 prefers — the requirement is only that a KEK exists and is not in source | Yes |
23:| 7a | Credential to reach the external KMS, **only if 04 exercises the KMS alternative in row #7** (a role, API key, or client cert — whichever the chosen KMS uses) | Whichever binary holds the KEK reference (#7) | Same discipline as every other row here: runtime-injected, never in source, never provisioned ad hoc outside this table | Per the KMS provider's own rotation mechanism | Cloud-KMS access is typically workload-identity-based (no static credential to store) rather than a `Secret` object; if the chosen KMS instead requires a static credential, it gets its own `Secret` under the same RBAC discipline as row #2 | Yes |
24:| 8 | TLS serving private keys for `api-service` and `idp-connector` | Ingress / each binary, per 04's termination choice | Runtime-injected; TLS 1.2+ only; certificate validation never disabled in any environment (`connector-security.md` §2) | Per certificate lifetime; automated issuance preferred | `kubernetes.io/tls` `Secret`; issuance mechanism is 04's call | Yes |
26:| 10 | `api-service`'s own client credential (`client_id`/`client_secret`) toward the issuer, scoped `connector:identity-lookup`/`aud: idp-connector-service` — required for `api-service` to call `idp-connector`'s own authenticated `/auth`/`/identity` (`connector-security.md` §5) | `api-service` (the Deployment serving question 2's API, acting as a caller of the connector on a user's behalf) | Runtime-injected; never in source or committed config — same discipline as row 5's vendor registration, added by the cross-track consistency pass (F15), which found this credential asserted as a requirement in `connector-security.md`/`handoff-03-auth.md` with no inventory row | Same per-client rotation as row 4 (revoke by deleting the issuer-side hash) | File mount, one `Secret`, `api-service`'s own ServiceAccount | Yes |
32:- **Secrets at rest in etcd are base64, not encrypted, by default.** Either enable encryption at rest for the `Secret` resource type, or source values from an external store that never writes plaintext to etcd. One or the other; the design must say which.
33:- **RBAC:** no service account may `get`/`list` Secrets it does not mount. The operator agent's apply rights are a documented trust boundary, not a hole to close in this take-home — but the design should note that its scope could be narrowed to a namespace.
34:- **Manifests carry references, never values.** Any manifest in the repository contains Secret *names*; values are provided out-of-band. This is what keeps assumption 3 honest.
37:- **Audit/access logs (the output of the never-log list below) are readable only by an incident-review role, distinct from and narrower than general operator access.** `sub`, scope, record id, and timestamp are enough on their own to reconstruct who looked up whom — that log stream needs its own read restriction, separate from whichever service account can `get`/`list` the Secrets in this table. Mechanism (log-pipeline RBAC, a separate log sink with its own access control, etc.) is 04's call; the requirement is that "can read Secrets" and "can read the audit trail" are not the same grant.
38:- **The CI deploy ServiceAccount (`loginid-takehome-deployer`) must not be able to read row #2's JWT signing-key Secret, even though it holds Secret verbs to manage the app's other Secrets in the same namespace** — found by Tobias Lindqvist: a namespace-scoped Role with broad Secret verbs is a straight-line path from "CI runner compromised" (a real risk for a repo-scoped ARC runner with GitHub App auth in a public repo) to "mint arbitrary tokens." Two controls required together, not either/or: (1) **the signing-key Secret is created out-of-band**, in a one-time `bootstrap.yaml` applied outside the CI-managed manifest set (by a human or a separate, more privileged process) — so under normal operation CI never needs a verb on it at all; (2) **the deployer Role's `secrets` verbs are scoped with `resourceNames`** to an explicit allow-list of the app Secrets CI is meant to manage, which never includes the signing-key Secret's name. (1) alone is operational hygiene, not an enforced boundary — a broad, unscoped Role verb still reaches any Secret that exists in the namespace regardless of who created it; (2) is the actual RBAC control, and is the one to name as the enforcement site in a review. If maintaining a `resourceNames` allow-list becomes unworkable as the Secret count grows, the fallback is putting the signing-key Secret in a separate namespace the deployer Role has no grant over at all — 04's call which of the two shapes fits the manifest set better, but one of them must be in place before this is called done.
65:4. **No RBAC on audit-log read access.** Accepted. Added a requirement under Kubernetes-specific requirements that Secret-read and audit-log-read are distinct grants.
