I'd rather they go through a PR than ride a milestone commit — the A6 defects were found by comparing two statements against each other, and a PR is the artifact that makes doc changes reviewable that way. The branch now matches my working tree exactly, so nothing is left behind for the milestone commit to sweep up.\n\n**One thing in there is worth your attention for the record**, because it's a correction to how this track reviews rather than another finding. I approved PR #24's first form; Nolan Reyes caught that a corrected `CHECK` inside an already-applied migration is **correct text and a no-op** — live databases keep the old constraint while the file, the tests and the reviewer all look right. My checklist reviewed migration file *contents* and never asked whether a change would apply.\n\nHis framing is the part I'd put in LOG.md, not the catch: *three strikes on the same blind spot is a process gap worth fixing once, not a scorecard.* So §7 now states the principle a single time — **verification exercises the sequence the live system executes, not an idealized construction of the end state** — with the four defects that produced it listed, and the checklist cites it rather than restating it. Four instances across this project, every one found by somebody running the real thing rather than reading it.",

  "message": "Heads-up before you apply `ddl-review-checklist.md` to LT-51's issuer client store: **most of it doesn't apply, and ticking it wholesale would give you false confidence.** It was written for *my* schema, not as a general DDL standard, and I'd rather say so than have it used as one.\n\n**What transfers — the universal half:**\n\n- **Every constraint named** (items 4–5 in spirit, not the specific names). The reason is engine-independent: error translation matches on structured code *plus* constraint name, never message text, because messages aren't portable. Any table whose violations map to a sentinel needs named constraints. The specific names in item 5 are mine and mean nothing there.\n- **Section G entirely** (items 20–23) — applied migrations are immutable, corrections ship as a new numbered migration in every affected directory, verify by incremental apply rather than fresh schema, and CockroachDB needs `-- +goose NO TRANSACTION` for a same-transaction `DROP`+`ADD`. These are properties of goose and the engines, not of my tables.\n- **The §7 principle behind them** — verification exercises the sequence the live system executes.\n- **The A6 rule**: any validation expressed twice in different dialects must accept exactly the same set, written down rather than named. If the client store runs on one engine only, this is moot; if it doesn't, it's the one most likely to bite.\n- **Absence single-valued** — NULL means absent, `''` rejected by a CHECK. Cheap, and it's why our address columns never needed a \"which representation is this\" branch.\n\n**What does not transfer:** items 5–19 are about `user_profile`/`user_credential`/`auth_method`/`deletion_log` specifically — the phone E.164 constraints, `COLLATE \"C\"` on `name`, the trigram expression index, `country` normalization, the `secret_state` tying CHECK, the cascade asymmetry, `deletion_log`'s no-FK and no-PII rules, and the `auth_method` seed. A client store has none of those columns. **Ticking them means nothing; skipping them means nothing either.**\n\n**And what the checklist has no opinion on, which is where I'd actually look.** A client store holds registered OAuth/OIDC clients — so it holds **client secrets**, which puts it in the same category as `user_credential` and under 02's second-review rule rather than mine. The questions that matter there are ones my checklist never asks: is the client secret stored hashed rather than recoverable; is there a `secret_state`-equivalent making \"no secret\" and \"secret set\" distinguishable; does anything cascade; and does it carry PII at all, since if it does it acquires a retention clock and currently has none. **Those are 02's and possibly a new governance row, not a DDL checklist item.**\n\nPer F8 the schema itself is the issuer's and not mine, so I'm not claiming it — but I'll review the DDL if you want a second pair of eyes, on the universal half plus whatever 02 rules on secrets.\n\nAlso standing by for the provisioning + migration Job story when Naomi pulls it. The thing I'll check there is that the Job runs **backend directory first, then `shared/`** — inverted in my own doc until recently — and that it invokes goose against the real migration files rather than reimplementing the sequence.",

Migration Job order and idempotency — PASS\n\n`postgres/` then `shared/`, separate version tables (`goose_db_version_postgres`, `goose_db_version_shared`), `set -e` so a failed first invocation aborts the second. That last detail is the one that matters and it is right: R4a requires **both** invocations to succeed for the run to count, and without `set -e` the Job would have exited 0 with the seed applied against a half-migrated schema.\n\nIdempotent on re-run by goose skipping applied versions, with `backoffLimit: 2` and `restartPolicy: Never`. Correct.\n\n### 2. Role split — PASS on the wiring, **one likely blocker on the grants**\n\nThe wiring is right: `api-service` receives only `DB_DSN_FILE=/secrets/db/dsn` mounted from `db-runtime-credential`, never the migrator DSN, and never a DSN in an environment variable. File-mounted beats env for exactly the reason check 4 exists — an env DSN surfaces in `env` dumps, crash reports and debug endpoints.\n\n**Likely blocker: `migrator` appears to lack `CREATE` on schema `public`.** The image is `postgres:16-alpine`. The comment correctly notes that PG15+ removed `CREATE` on `public` from `PUBLIC` — which is what stops `runtime` doing DDL, and that reasoning is sound. But the same change also means schema `public` is owned by `pg_database_owner`, and **`GRANT ALL PRIVILEGES ON DATABASE` grants `CREATE` on the *database* (i.e. create schemas), not `CREATE` on schema `public`.** `migrator` is not the database owner — `postgres` is.\n\nExpected symptom: the Job's first `goose up` fails on the first `CREATE TABLE` with `ERROR: permission denied for schema public (SQLSTATE 42501)`.\n\nIf so the fix is one line in the initdb script: `GRANT CREATE ON SCHEMA public TO migrator;` (or make `migrator` the owner of the database).\n\n**Falsifiable rather than asserted — I have not run this.** I raised a docs-derived finding against PR #6 that a live test disproved, so: **has the migration Job run green against this manifest on a real cluster?** If it has, my reading is wrong and I withdraw this immediately; please pin the evidence the way we pinned CockroachDB v23.2.0. If it hasn't been run, this is worth running before merge rather than discovering at deploy.\n\n**Also worth naming — a coupling between your grant and my schema.** `ALTER DEFAULT PRIVILEGES … GRANT … ON TABLES` grants nothing on **sequences**. That is correct today *only because* `multi-db-strategy.md` §5 uses UUID primary keys everywhere and the schema contains no sequence. If anyone ever adds a `SERIAL`/identity column, `runtime` will be unable to use its sequence and the failure will look unrelated to this manifest. Not a change — a dependency worth having written down.\n\n### 3. goose version-table uniqueness — STILL OPEN, correctly\n\nNothing in this PR addresses it and nothing should. `migration-approach.md` R2 records it as unverified, with a recommendation that does not depend on the answer: add a unique index on `version_id` in the first migration, which costs nothing if goose already does it. That belongs in a migration (03's), not in a manifest (yours). **Still flagged, not resolved** — confirming rather than closing it.\n\nWorth noting it matters slightly less here: R2's single-runner requirement is met by the Job's `parallelism` defaulting to 1 with `restartPolicy: Never`, which is the platform-level exclusivity R2 asks for.\n\n### 4. Secret leakage — PASS, one low-severity note\n\n`db-secret-bootstrap.yaml` is documentation only — the `kubectl create secret` invocations are commented examples, no material in the repo. The deploy workflow references only `secrets.GITHUB_TOKEN`, with no `set -x` and no echoing of a DSN or password. The migration Job's script uses `set -e`, not `set -x`.\n\n**Low severity:** `MIGRATOR_DSN` is passed to goose as a **command-line argument**, so the password is visible in `ps` output to anything sharing the pod's PID namespace, and in any crash handler that captures a process listing. goose reads `GOOSE_DBSTRING` from the environment, so this is a small change that removes argv exposure. Not blocking, and notably `api-service` already does the stronger thing by reading a file — the pattern is in the PR, just not applied here.\n\nOne for 02 rather than me: the DSN examples use `sslmode=disable`. In-namespace over the service network, plausibly fine, but it is a security call and not a data one.\n\n---\n\n**Summary:** checks 1 and 4 pass; check 2 passes on wiring with a likely blocker on grants that needs one line if confirmed; check 3 remains open by design. Happy to re-review immediately on the schema-grant answer.\n\n**Work-By:** Priya Nandakumar (05 Data Ops lead, Claude Opus 5) — LT-52 review.\nEOF\ngh pr comment 29 --body-file /tmp/claude-501/pr29-review.md 2>&1 | tail -1",

Expected symptom: the Job's first `goose up` fails on the first `CREATE TABLE` with `permission denied for schema public` (42501). Fix if confirmed is one line: `GRANT CREATE ON SCHEMA public TO migrator;`.\n\n**Stated falsifiably, not asserted — I have not run it.** I raised a docs-derived finding against PR #6 that a live test disproved, so the question back to 04 is whether the Job has run green against this manifest on a real cluster.

That consistency is the part worth checking rather than assuming: a server switched to SSL while one of two DSNs still said `disable` fails at connect time for exactly one role, which reads as a credential problem rather than a TLS one.\n\n### Check 1 re-verified, because the rewrite could have silently dropped it\n\n`set -e` intact; order still `postgres/` then `shared/`; distinct `-table` values per invocation.

Correct as written.\n\n**It is correct because the mount is `readOnly: true`.** That makes the applied mask read-only (`0440` → final `0640`). On a read-write mount the mask becomes `0660`, the key becomes group-*writable*, and **PostgreSQL then refuses to start** — it rejects a group-writable private key outright. So removing `readOnly: true` from that volume, which looks like a harmless permissions loosening, breaks SSL startup with an error pointing at the key file rather than at the mount.\n\nWorth a comment next to `readOnly: true` on the `server-tls` volume saying it is load-bearing for key permissions, not just hygiene.

  "summary": "LT-51 client store ruled — shape, table, seeding",
  "message": "**Ruled. Your default is right on the physical shape; the table needs four changes, three of which are lessons this project has already paid for.**\n\n## Physical shape — confirmed, with the reason stated\n\n**Separate database `issuer` in the same Postgres instance.** Not a separate schema. The reason matters more than the choice: PostgreSQL cannot join across databases without FDW, so a separate database makes a join between `oauth_client` and `user_profile` **structurally impossible rather than merely discouraged.** That is the same argument as the PII/credential split in my own contract — a governance control enforced by structure, not convention. A schema split would leave it to role grants, and role grants drift.\n\nAccepted risk, named rather than hidden: same instance means one compromised superuser reaches both stores. Separate instances would be the hardening step; for a POC this is the right point on the curve, and it should be written down as a decision rather than an oversight.\n\nRoles `issuer_migrator`/`issuer_runtime` with the LT-52 DDL-denial pattern: yes. **And it needs the LT-52 grant fix, or it fails identically** — `GRANT CREATE ON SCHEMA public TO issuer_migrator;` in its initdb, since `GRANT ALL PRIVILEGES ON DATABASE` does not confer `CREATE` on schema `public` on PG15+. That finding transfers directly; please make sure Theo carries it rather than rediscovering it.\n\n`migrations/issuer/` as a third goose invocation in the same Job: yes, **with its own DSN** — a different database means a different `GOOSE_DBSTRING`, not just a different `-dir`. Order it last, after `postgres/` then `shared/`, with `set -e` so a main-schema failure still aborts it. Version table `goose_db_version_issuer` in the issuer database. One caution for R3: fail-closed is now per-service — `api-service` checks the two main version tables, the issuer service checks its own. They are different databases and must not check each other's.\n\nNetworkPolicy: endorsed, and the corollary is that `api-service`'s pod must not be able to reach the issuer database at all, not merely be uncredentialed for it.\n\n## Table — four changes\n\n```\noauth_client\n  client_id          TEXT PK      ck_oauth_client_id_charset: 8–64 chars of [A-Za-z0-9._-]\n  name               TEXT NOT NULL, non-empty CHECK\n  client_secret_hash TEXT NULL    Argon2id PHC string\n  secret_state       TEXT NOT NULL  ck: 'none' | 'set' | 'revoked'     ← NEW\n  granted_scopes     TEXT[] NOT NULL\n  status             TEXT NOT NULL  ck: 'active' | 'disabled'\n  created_at         TIMESTAMPTZ NOT NULL\n  updated_at         TIMESTAMPTZ NOT NULL                              ← NEW\n```\n\n**1. `secret_state` is the important one, and it is a defect we have already found once.** A nullable `client_secret_hash` collapses three distinct states: a *public* client that never has a secret (PKCE), a confidential client whose secret is not yet set, and one whose secret was revoked. That is exactly what Yusuf found in `user_credential`, and the fix is the same — an explicit state plus a table-level CHECK tying it to the hash, so a row with a secret and state `none` is unrepresentable rather than merely discouraged. Without it, \"is this client allowed to authenticate?\" is answered by a NULL check that cannot distinguish \"never had one\" from \"we took it away.\"\n\n**2. `client_id` is `TEXT`, not UUID, and its accepted set is written down** — per A6, a validation expressed once must still state what it accepts. OAuth client_ids are frequently chosen rather than generated, so a UUID constraint would be wrong; but an unconstrained `TEXT` primary key invites whitespace and case variants of the same id. 8–64 chars of `[A-Za-z0-9._-]`, named constraint. **A4's canonical-form rules do not apply here** — say so explicitly, or someone will apply them by analogy.\n\n**3. `updated_at`.** Secret rotation and disabling are the two things that will happen to these rows, and neither is observable without it.\n\n**4. `status` and `secret_state` are independent and both needed.** A disabled client with a valid secret and an active client with a revoked secret are both real states. Do not let anyone collapse them into one column.\n\n**On `granted_scopes TEXT[]`:** fine, **and the issuer store is PostgreSQL-only** — deliberately. The assignment's multi-database requirement is on the user-profile DAO, not on every datastore in the system. Stating that explicitly so nobody \"helpfully\" makes this portable. The trigger to revisit: if the issuer ever needs to run on SQLite for local dev, `TEXT[]` is the first thing that breaks and becomes a join table.\n\n**Governance: `oauth_client` carries no PII and must not acquire any.** No contact email, no owner name. As written it is registration metadata, so the issuer database has **no retention clock** — which is why it can sit outside `pii-governance.md` entirely. **If a contact email is ever added, that changes: the store acquires a subject, a retention clock and a deletion path, and it becomes a governance item rather than a schema one.** Worth a comment in the DDL at the point someone would add the column.\n\n## Seeding — out-of-band, and here is the general rule\n\n**Agreed, and more strongly than you put it.** A migration-seeded hash is a credential committed to a **public repository**, permanently in git history and unrotatable — Argon2id makes it expensive to crack, not safe to publish, and it would be a live credential for a deployed system rather than a test fixture.\n\nThe principle worth stating once, because it also explains why `auth_method` *is* seeded by migration: **migrations carry reference data, never credentials.** `auth_method`'s `'password'` row is reference data — no secret, identical in every environment, and required for the schema to function. A QA client row is a credential, and credentials are provisioned the way `db-secret-bootstrap.yaml` does it: documented commands, no material in the repo.\n\nThe cost, named: a fresh environment has no QA client until someone runs the step, so it needs to be in the deploy runbook rather than implied. That is the right trade — a missing test fixture fails loudly, a published credential fails silently.\n\n---\n\nHappy to review the DDL the same way as LT-36 — send it when Renata has it. The checklist applies in its universal half only (named constraints, section G on migration immutability, the A6 same-set rule); items 5–19 are about my tables and mean nothing here.

Demo data does not: nothing breaks without it, and it belongs to exactly one environment.\n\nThat rules out (a) on principle before we get to mechanics.\n\n## Why (a) is wrong on mechanics too — its enforcement site is a flag\n\n(a)'s guarantee is \"the Job runs `dev-seed/` only when an env flag is set.\" **The enforcement site is a string comparison in a manifest** — precisely the class of guarantee this project has spent six amendments moving *out* of places that drift. A flag gets copied into a production overlay, or defaults wrong once, and synthetic PII-shaped rows land in the real database. **The failure is silent:** a synthetic row in production looks exactly like a real one, and nothing detects it afterwards.\n\nWorse, putting the file under `migrations/` at all means goose *can* apply it — one wrong `-dir` and it is in, flag or no flag.\n\n**(b)'s enforcement site is that no code path exists.** The Job cannot run the file because the file is not in any directory the Job knows about. That is an enforcement site that cannot drift, because there is nothing to misconfigure.\n\n## The refinement: version-control the file, just not as a migration\n\nPut it at **`deploy/demo-data/001-review-profiles.sql`** — in the repo, reviewable, diffable, reproducible — and have Theo apply it as a documented runbook step, exactly as `db-secret-bootstrap.yaml` documents secret creation. That keeps (b)'s strong enforcement while removing its real weakness, which is that a purely manual step is unreproducible when the review environment is rebuilt.\n\nTwo requirements on the file itself:\n\n- **Idempotent** — `ON CONFLICT DO NOTHING`, so re-running the runbook after a redeploy does not duplicate rows. Same rule as the `auth_method` seed.\n- Applied with the **migrator** role. `runtime` could do it — it is DML — but this is an operational action, not application traffic, and the two should not share a credential.\n\n## Retention — they are governed exactly as real rows, and that is deliberate\n\n**Synthetic rows fall under `pii-governance.md` in full, on the same clocks and the same sweep.** Not because they have a data subject — they do not, so storage limitation does not apply to them *as such* — but because **nothing can distinguish them from real rows by inspection.** A retention sweep selects on `source` and a clock; synthetic rows have both. A subject-deletion request matching a phone number could match one. Nobody auditing the database could *prove* a given row is fictional.\n\nClaiming an exemption would require a marker, and **I am explicitly not adding one.** A `source = 'synthetic'` value would be a contract amendment that exists only to serve demo tooling, leaking a review-environment concern into the production schema — and it would create a second class of row that every future query and sweep has to remember to handle. That is a worse trade than governing a handful of fake rows identically to real ones.\n\n**The isolation is environmental, not per-row.** The review environment is not production, and no real data ever enters it. That boundary is the control; the row-level story is deliberately uniform.\n\nTwo practical requirements that follow:\n\n- **Phones in reserved/fictional E.164 ranges, names and addresses obviously fictional.** If a row ever did escape its environment, it should be identifiable as non-personal by inspection — the only mitigation available once row-level marking is off the table.\n- The data must satisfy every CHECK in §5 — E.164 format, `country` upper-case alpha-2, non-empty address columns, valid `source`. **That is a free test of the schema**: if plausible demo data cannot be written, a constraint is wrong.\n\n## One consequence worth flagging now\n\nIf the review needs a **login** and not just search/read, the `user_credential` row carries a password hash — which makes it a **credential**, not demo data, and it goes out-of-band with no hash in the repo, exactly like the QA client row in LT-51. The `user_profile` rows can be version-controlled; a credential for them cannot. Worth deciding before the runbook is written rather than after.",

A comparison helper handed a nil hash can panic, can error, or — worst case — can treat an empty comparison as a match. **The demo data will be the first thing to put that row in front of the auth code.** One line to Renata now is cheaper than discovering it at the review URL, and it is a genuine hole in §7's assertions: nothing currently asserts that a `secret_state='none'` credential *fails* authentication.\n\nIf she confirms it is handled, I would add that as a conformance assertion rather than leave it to the demo data to discover.\n\n**3. Concrete phone values, so nobody has to guess at the CHECKs.** Both of these satisfy the Postgres regex and the SQLite `GLOB` form — which, per A6, now accept exactly the same set, so anything valid in one is valid in the other:\n\n- `+12025550142` — 11 digits; US area code with the 555-01xx range reserved for fiction.\n- `+447700900123` — 12 digits; Ofcom's reserved drama range.\n\nBoth are E.164-valid, obviously non-real to anyone who knows the ranges, and within the 7–15 digit window. `country` must be upper-case alpha-2 (`US`, `GB`), `source` must be `'direct'`, and every address column present must be non-empty — NULL is fine, `''` is rejected.\n\nI will review the file when it appears. The CHECK-satisfaction test is the part I am most interested in: if plausible demo data cannot be written without fighting a constraint, the constraint is wrong and that is worth knowing before a reviewer sees the schema.",

  "summary": "Demo file is NOT on main — PR #32 merged without it",
  "message": "**Before the review — the file is not going to reach main, and I think it's about to be lost.**\n\nPR #32 is **MERGED** (base `main`), and its diff contains only `deploy/manifests.yaml`. Your commit **`6f6fc94` \"Add review demo-data SQL, per Priya's ruling\" is on `fix/ingress-profiles-routes` but is not on `main`** and is not in any open PR — `git log origin/main..origin/fix/ingress-profiles-routes` returns exactly that one commit. It looks like it landed on the branch *after* #32 merged, so it was never part of what got reviewed or merged. When that branch is deleted, the file goes with it.\n\nIt needs a new PR. Same shape as Desmond's catch a while back: the artifact existed, just not where anyone would find it — and `git status` on a branch looks identical whether the work is merged or stranded.\n\n## Content review — the file itself is good, and passes the test I wanted it to\n\n**The CHECK-satisfaction test passes cleanly**, which was the point of this exercise: plausible demo data went in without fighting a single constraint. That is real evidence the schema is usable rather than merely consistent.\n\nVerified line by line:\n\n- **UUIDs are canonical 36-char lowercase hyphenated** — A4-compliant, which matters because a non-canonical id would be rejected by the validator on every read path. `...-4000-8000-...` is even correctly v4-shaped.\n- **All three phones satisfy both engines' constraints**, which after A6 accept exactly the same set: `+12025550142` (11 digits), `+441134960001` (12), `+16135550199` (11) — all inside the 7–15 window, all `[1-9]` leading, no non-digits. Ranges are genuinely reserved: NANP 555-01xx and Ofcom's Leeds drama range.\n- **`secret_state = 'none'` with `secret`/`hash_algo`/`hash_cost` all NULL** satisfies the tying CHECK, and your comment is right that it is by construction rather than by omission someone must remember.\n- `country` upper-case alpha-2, `source = 'direct'`, every present address column non-empty, `BEGIN`/`COMMIT` for atomicity, and **outside `migrations/`** — the enforcement site holds.\n- **`region` NULL on the GB row is a nice touch**: it exercises the NULL-versus-empty-string distinction that §5 spends a CHECK enforcing, so the fixture tests the rule rather than just avoiding it.\n- `ON CONFLICT (LOWER(username))` matching the expression index: you verified it empirically against real Postgres with a second run as a clean no-op, which settles it. I would not have accepted that from a reading.\n\n## One small addition\n\n**State the migration dependency in the runbook comment.** The credential insert resolves `method_id` via `(SELECT id FROM auth_method WHERE name = 'password')`. If the `shared/` seed has not been applied, that subquery returns NULL and the insert fails a NOT NULL constraint, rolling back the whole transaction. That is a loud failure and therefore acceptable — but the comment currently says to apply this \"after LT-51 lands,\" which is about the issuer, not about the seed. Worth one line: **apply after the migration Job has run, including `shared/`** — otherwise the first person to run it against a fresh database gets a constraint violation that reads like a schema bug rather than an ordering mistake.\n\nOptional, take it or leave it: the `001-` prefix invites someone to read this as a versioned migration series. `review-profiles.sql` would carry less suggestion.\n\nApproving the content. Open the new PR and I will re-review there so it has a review on the record.",

-- impossible, not just policy-forbidden. Its own goose invocation
-- (GOOSE_DBSTRING pointed at this database) and its own version table

-- responsibility, not this file's.
--
-- oauth_client has no PII columns, ever (Priya's ruling) — client_id and

-- no retention clock on this table (contrast user_profile/

--
-- secret_state mirrors user_credential.secret_state's own lesson (05's
-- ruling, cited directly): three states (none/set/revoked) must be
-- asserted explicitly by a named CHECK, never collapsed into an
-- incidental "hash IS NULL" inference — a row can be `revoked` with a
-- NULL hash for a reason distinct from `none` never having had one.
--
-- client_id's charset CHECK is this table's own identifier rule —
-- 05-data-ops/multi-db-strategy.md amendment A4 (canonical UUID
-- validation) is explicitly NOT applied here, since client_id is a
-- human/CI-assigned slug (e.g. issued by the QA seeding runbook), not a
-- generated UUID primary key like every other table in this project.
--
-- granted_scopes is TEXT[] — deliberately PostgreSQL-only, unlike the

And a CHECK constraint fails only on FALSE; **NULL passes.** So `granted_scopes = '{}'` satisfies this constraint, and a client with *no* scope is insertable by exactly the rule written to prevent it.\n\nThe comment says the intent is \"exactly one scope, not merely a nonempty set.\" As written it is neither: it rejects two or more, and admits zero.\n\n```sql\nCONSTRAINT ck_oauth_client_granted_scopes_single\n  CHECK (cardinality(granted_scopes) = 1\n         AND granted_scopes[1] IS NOT NULL\n         AND length(trim(granted_scopes[1])) > 0)\n```\n\n`cardinality` returns 0 for the empty array, so `0 = 1` is FALSE and the row is rejected. The two extra clauses close the neighbouring hole: `ARRAY[NULL]::text[]` and `ARRAY['']::text[]` both have cardinality 1 and would otherwise pass, giving a client one scope that is not a scope.\n\nThis is the A6 rule landing on a new table: **the accepted set is what the expression accepts, not what the comment says it accepts.** Worth checking by insertion rather than by reading — `INSERT … granted_scopes = '{}'` is a two-line test.\n\n### 2. `updated_at` has no mechanism to ever update\n\nDefaulted to `now()` and never touched again by anything in this DDL — no trigger, and unlike the main DAO, no contract clause making the writing layer responsible. Secret rotation and disabling are the two things that will happen to these rows, and both are exactly what `updated_at` exists to record. As it stands it will equal `created_at` for the lifetime of every row, which is worse than not having the column: a reader will reasonably believe it means something.\n\nEither a `BEFORE UPDATE` trigger setting `updated_at = now()`, or an explicit statement that the issuer's write path sets it — with the second recorded somewhere the issuer's author will see it. I don't mind which; I mind that neither exists.\n\n### 3. `name` was already in the ruling — not an amendment\n\nFlagging it was the right instinct, but my LT-51 message specified `name TEXT NOT NULL, non-empty CHECK`. Nothing to approve; it is implemented as ruled.\n\n### 4. `audience` — accepted, with the asymmetry noted\n\nCorrect addition and correctly reasoned: `idp-connector` and `api-service` are different audiences, and without a per-client value there is nothing to put in `aud`. Not PII. Approved as an amendment.\n\nOne thing to record rather than change: **`granted_scopes` is an array constrained to exactly one element, while `audience` is a scalar** — both are \"exactly one,\" expressed two different ways. That is defensible (scope is conceptually a set that may later admit more; audience is not), but if the single-scope commitment ever relaxes, the scope CHECK is the thing that changes and `audience` is the thing someone will forget to reconsider. A line in the comment naming that would help.\n\n### 5. `client_id` is case-sensitive — say so\n\n`TEXT` primary key with a charset CHECK, so `Client-A` and `client-a` are **distinct rows**. That is normal for OAuth client identifiers and I am not asking for a change — but `user_credential.username` in the main schema is case-*folded* for uniqueness, so a reader moving between the two schemas has every reason to assume the same rule applies here. One comment line prevents someone \"fixing\" the inconsistency later.\n\n### Passes\n\nSeparate `issuer` database with its own version table and DSN, as ruled — the structural-impossibility argument for the cross-database join is recorded accurately. Every constraint named. `secret_state` present with a tying CHECK, and correctly simpler than `user_credential`'s since an Argon2id PHC string is self-describing and needs no `hash_algo`/`hash_cost`. `client_id` charset matches the ruling, and A4 is correctly *not* applied, with the reason stated. `TEXT[]` deliberately PostgreSQL-only, reason recorded. No PII columns, no retention clock, and the contrast with the main schema is written down. `goose Down` present. No `NO TRANSACTION` needed — this is a fresh `CREATE TABLE`, not a `DROP`+`ADD`.\n\n**Verdict:** fix finding 1, resolve finding 2 either way, add the two comment lines, and this is approved from 05.\n\n---\n\n**Work-By:** Priya Nandakumar (05 Data Ops lead, Claude Opus 5) — DDL review against the universal checklist items and the LT-51 ruling.\nEOF\ngh pr comment 34 --body-file /tmp/claude-501/pr34-review.md 2>&1 | tail -1",

All three were caught by someone checking `git diff origin/main -- <path>` rather than trusting a branch's state.\n\nThe general form, since it keeps recurring: **\"the work exists\" and \"the work is where it will be found\" are different claims, and only the second one ships.**\n\n---\n\n**Work-By:** Priya Nandakumar (05 Data Ops lead, Claude Opus 5) — re-review and approval.

  "message": "I'll review #36 once it's rebased and the stale files are out. **The initdb divergence question I can answer now, and the answer is yes — emphatically, and a PR body is the worst available place for it.**\n\n## Why this is a standing mechanism, not a one-off\n\n`docker-entrypoint-initdb.d` scripts fire **only when the data directory is empty**. With a PVC, that means exactly once in the instance's life. So this is not \"Theo had to hand-apply this time\" — it is **\"every future edit to the initdb ConfigMap will also silently not apply, forever.\"** The manifest describes what a *fresh* database would get; the live database got something a human typed. Nothing compares them, and nothing ever will unless we build it.\n\nThat is the §7 principle in a new costume: the thing that ran and the thing that is written down are different artifacts, and only one of them is under review.\n\n## Where it needs recording — three places, in order of value\n\n**1. A comment at the top of the initdb ConfigMap itself.** This is the enforcement-site rule: record it at the line where someone would make the mistake. Someone editing that script in three months will add a `GRANT`, deploy, see nothing happen, and lose an afternoon before they discover the PVC semantics. Same class as the `readOnly: true` and sequences caveats already in these manifests — a property that is true for a reason invisible where it bites.\n\n**2. A runbook with the apply-by-hand procedure**, alongside `db-secret-bootstrap.yaml` and the QA-client bootstrap. Whatever Theo typed by hand is currently unreproducible; if that instance is ever rebuilt onto a fresh PVC the initdb path takes over and the hand steps are wrong-but-harmless, and if it is *not* rebuilt they are the only way the roles exist.\n\n**3. Not in `migration-approach.md`.** That document is about goose and schema migrations; role and database provisioning is 04's surface. Putting it there would blur a boundary this project has kept clean.\n\n## One concrete ask before merge — cheap, and I think necessary\n\n**Verify the live issuer roles and grants actually match the manifest as it will merge, and record the evidence in the PR.** `\\du`, `\\l`, and `\\dn+` output, or the equivalent queries.\n\nThe reason is specific rather than procedural: **we found `GRANT CREATE ON SCHEMA public` missing from the main database's initdb only two days ago.** If the issuer roles were hand-applied from an earlier draft, or typed from the same assumption that produced that omission, the live `issuer_migrator` may be missing exactly that grant — and the symptom appears at the first `CREATE TABLE` of the issuer migration, which is after merge. Ten seconds of `\\du` now versus a failed deploy later.\n\n## The real fix, named but not demanded\n\nIf this outlives the POC, role and database provisioning should be an **idempotent Job** rather than initdb — `DO $$ BEGIN CREATE ROLE … EXCEPTION WHEN duplicate_object THEN NULL; END $$` and grants that are safe to re-run — so the manifest converges the live state on every deploy instead of describing a state nobody can verify. That converts a one-shot into a convergent operation and removes the divergence class entirely.\n\nI am **not** asking for that now; it is scope beyond LT-51 and Theo has a working instance. But it should be recorded as the known-correct shape, so that when someone hits this a third time the answer is already written down rather than rediscovered.",

Then I reviewed two PRs, answered the initdb divergence question, and wrote you a paragraph whose closing line was *\"'the work exists' and 'the work is where it will be found' are different claims, and only the second one ships.\"* It was sitting uncommitted on my disk the entire time I was writing that sentence.\n\nI only caught it because I made a habit of running `git diff origin/main -- 05-data-ops/` before standing by, after Desmond's catch taught me that \"modified in the shared tree\" and \"absent from origin/main\" are different questions. The habit worked; my attention did not. **That is the argument for mechanical checks over careful people, made at my own expense** — and it is the same argument as seam 13, the conformance suite, and the incremental-apply rule.\n\nThe tally is now four: a contract amendment on my disk while 03 implemented against it; a Jira description transcribed before a fix landed; Theo's demo-data commit stranded on a merged branch; and this.

The third `psql` reconnects with `--dbname issuer`, so they land where they must. Had they run against `$POSTGRES_DB` it would have been two bugs at once — `issuer_migrator` silently granted CREATE on the *main* database's schema, and the issuer migration failing at its first `CREATE TABLE` with exactly the error LT-52 already taught us. It is correct, and the three-invocation split is correctly reasoned: `CREATE DATABASE` alone because psql sends a multi-statement string as one implicit transaction, roles separately because they are cluster-wide, grants last against the right database. Verified empirically rather than asserted, and the reasoning is in the file.\n\n**Third goose invocation — PASS.** `GOOSE_DBSTRING=\"$ISSUER_GOOSE_DBSTRING\"` (a different database needs a different DSN, not just a different `-dir`), `-table goose_db_version_issuer`, ordered last, under `set -e`. All four properties present.\n\n**QA-client runbook — PASS.** No hash committed; `$HASH` is sourced from the generator at run time. Rotate and revoke are both documented, and **revoke sets `client_secret_hash = NULL` because the tying CHECK requires it** — that is the schema understood rather than merely satisfied, which is the difference between a runbook that works and one that works until someone follows it.\n\n**Four conditions — all met.** Empty-PVC semantics stated at the top of the initdb ConfigMap, where the mistake would be made. Hand-apply steps documented alongside the secret bootstrap. The idempotent-provisioning-Job future shape recorded with the right detail — including that Postgres `GRANT`s are themselves idempotent while `CREATE ROLE` is not, which is the part someone would get wrong writing it.\n\n### Finding: the hash encoding is not a PHC string, and has no cost-migration path\n\n`gen-argon2-hash.go` emits `base64(salt)$base64(hash)`, with `time=1, memory=64MiB, threads=4` as compile-time constants in the generator and the verifier. My LT-51 ruling specified an **Argon2id PHC string**, and the difference is not cosmetic: a PHC string (`«REDACTED-ARGON2»`) carries its own parameters, and this encoding does not.\n\nThe consequence is a migration path that does not exist. The day anyone raises the cost profile — which NIST SP 800-63B explicitly anticipates, and which this project's own research doc quotes — **every existing hash becomes unverifiable**, because the verifier computes with new parameters against a hash produced under old ones and there is no per-row record of which was which. You cannot verify-with-old-then-rehash-with-new, because nothing says what \"old\" was. Every client fails authentication at once, indistinguishably from a wrong secret.\n\nThis is the same requirement `user_credential.hash_algo`/`hash_cost` exists to satisfy one table over. I ruled `oauth_client` needed no such columns *specifically because* a PHC string is self-describing — so with a non-self-describing encoding, the store is now missing both mechanisms.\n\nTwo fixes, either acceptable: emit a real PHC string (one `Sprintf` and a parser, standard format, no schema change), or add `hash_algo`/`hash_cost` columns mirroring `user_credential`. **I prefer the PHC string** — standard, tool-readable, no new columns.\n\n**Cheap now, expensive later**: changing a format before any hash exists costs an afternoon; changing it after costs a migration over live credentials you cannot read. Same asymmetry as naming constraints up front.\n\nNot blocking merge — nothing breaks today, and the hashing scheme is **02's** call rather than mine. I own the storage consequence and am flagging it as a deviation from the ruling so it is a decision rather than drift. Worth Marcus's ruling before it ships.\n\n### Ask: move the live-state evidence onto this PR\n\nThe `\\du`/`\\l`/`\\dn+`/`has_schema_privilege` output is on **#36, now closed**. Merge is gated on that evidence, and a closed PR is technically findable and practically invisible — anyone later auditing whether the live `issuer_migrator` grant was verified will read the merged PR. Please repost or link it here.\n\nIncidentally `has_schema_privilege` was better than the `\\du` I asked for: I requested the artifact I would have inspected, and you produced the assertion itself. Noted for next time I write a verification ask.\n\n**Verdict: PASS.** Approved from this track once the evidence is on this PR; the hash-encoding finding is recorded for 02 rather than held against this merge.\n\n---\n\n**Work-By:** Priya Nandakumar (05 Data Ops lead, Claude Opus 5) — review of issuer provisioning, migration Job, and QA-client runbook against the LT-51 ruling.\nEOF\ngh pr comment 38 --body-file /tmp/claude-501/pr38-review.md 2>&1 | tail -1",

So my earlier \"recorded, not blocking\" becomes **blocking**, on 02's authority rather than mine. Everything else in my review stands unchanged and still passes.\n\n### One trap worth naming before the code is written\n\n**Emitting a PHC string is not the fix. Verifying from the parsed parameters is the fix.**\n\nA verifier that parses `«REDACTED-ARGON2»`, takes the salt and the hash, and then recomputes using the **compile-time constants** produces a self-describing format with none of the property it exists for. Every hash would carry its parameters and nothing would read them — and the day the cost profile changes, every existing hash breaks exactly as it would today.\n\n**It would also pass a round-trip test**, which is what makes it worth saying out loud. Generate, verify, match — green, on a codebase where generator and verifier share the same constants. The round-trip proves the two halves agree with each other; it does not prove either reads the stored parameters.\n\nThe assertion that distinguishes them: **verify a hash whose embedded parameters differ from the current constants.** Construct one with, say, `t=2` and confirm it still verifies. That is the property; the round-trip is the mechanism. Same distinction as signature-versus-behavioural conformance in the contract's §7, and the same one that produced `verification exercises the sequence the live system executes`.\n\n### Paired change — both sides, or neither\n\n`deploy/gen-argon2-hash.go` (04) and `internal/api/clientstore.go`'s `hashSecret`/`verifySecret` (03) must change **together**. A generator emitting PHC against a verifier expecting `base64(salt)$base64(hash)` fails closed on every client, and the reverse fails just as hard. `deploy/demo-data/qa-client-bootstrap.md` also describes the old encoding in prose and needs updating in the same change, or it becomes a fifth restatement drifted from its source.\n\nThe QA runbook's existing round-trip verification should be re-run after the change — and extended with the differing-parameters case above, which is the one that has teeth.\n\n### Unchanged from my review\n\nIssuer database, roles and grants: pass, with the database-local grants correctly scoped by the third `psql` reconnect. Third goose invocation: pass. QA-client runbook: pass on credential handling. All four conditions met. **Ask still open:** the `\\du`/`\\l`/`\\dn+`/`has_schema_privilege` evidence is on closed #36 and merge is gated on it — please bring it onto this PR.\n\n---\n\n**Work-By:** Priya Nandakumar (05 Data Ops lead, Claude Opus 5) — verdict update.

Every input to the recomputation now comes from the stored hash.\n\n`subtle.ConstantTimeCompare` for the comparison.\n\n### The test has teeth — including the half that is usually missing\n\n`TestVerifySecret_ReadsEmbeddedParameters_NotPackageConstants` hand-builds at `t=2` via `argon2.IDKey` directly rather than through `hashSecret`, so it does not inherit the package's agreement with itself. It asserts the encoded string actually contains `,t=2,` first — a setup guard that catches a broken `encodePHC` pretending to be a passing test.\n\n**And it asserts the negative case**: the wrong secret against the same hand-built hash must fail. That was not in what I asked for and it is the half that matters — without it, a `verifySecret` that returned `true` unconditionally would pass the positive assertion and the whole test would be theatre.\n\n### Rehash-on-verify\n\nGated on `needsRehash`, inside the success path, failures logged and non-fatal so a storage problem cannot deny a client a token it has earned. The dummy-hash `verifySecret` on the miss branch keeps the timing behaviour uniform.

Three notes, none of which asks for a change today.\n\n### The CockroachDB-specific trap was already caught\n\n`DROP DATABASE … WITH (FORCE)` is PostgreSQL 13+ only, and CockroachDB **fails it as a syntax error rather than ignoring the option** — so a shared helper using it would break cleanup on one engine while looking fine on the other. The conformance helper deliberately omits it and says why; the postgres-only package keeps it, where it is correct. That is the right split and it is the exact thing I came looking for.\n\n### Verified rather than assumed\n\n- **Identifier safety.** `test_<prefix>_<int63>` is lowercase alphanumeric plus underscore, and `rand.Int63()` is non-negative so no leading minus. Safe unquoted on both engines — an unquoted identifier needing quotes would have been folded or rejected, and the DSN built from the same string would then point somewhere else.\n- **No deterministic-name collision.** `math/rand`'s global source is auto-seeded from Go 1.20; `go.mod` is at 1.27.1. On an older toolchain this would have produced the *same* database name every run, so a leftover from a crashed run would collide with `CREATE DATABASE` and fail the suite on the next invocation. Not an issue here.\n- **`CREATE DATABASE` runs standalone**, not inside a multi-statement exec — the LT-51 lesson, applied.\n- **Connection-close ordering is sound.** Cleanup relies on every per-test connection being closed by its own `t.Cleanup` before `TestMain`'s cleanup runs, and `m.Run()` does return only after those have executed. The reasoning in the comment is correct.\n\n### Three notes, for the record rather than for action\n\n**1. CockroachDB's `DROP DATABASE` is asynchronous.** It enqueues a schema-change job and returns; the data is GC'd later per `gc.ttlseconds`. Irrelevant for a container torn down after the run. It matters only if the CockroachDB instance is long-lived across many CI runs, where dropped databases' data lingers and disk accumulates. Worth knowing before someone decides to keep a warm CockroachDB around to save startup time.\n\n**2. Cleanup logs and continues on failure — so \"tests green\" does not mean \"no leftover databases.\"** That is the right design; a cleanup failure should not fail a passing suite. But it means the thing actually preventing accumulation is **the ephemeral container, not the cleanup code**. That is the enforcement site, and it is invisible from these files. If CI ever reuses a database server between runs, this becomes a slow leak that nothing reports.\n\n**3. Multi-node descriptor propagation.** Creating a database and immediately connecting to run migrations is fine against a single-node v23.2 container. On a multi-node cluster there can be a brief window before the new descriptor is leased everywhere, which would surface as an intermittent failure at the first migration. Stated as the trigger to revisit if CI ever runs against multi-node CockroachDB — **not a claim that it happens today, and I have not tested it.**\n\n### Worth saying\n\nThis is the fifth place in the project where the fix was to make the test exercise the real thing rather than an approximation of it — after the migration ordering, the SQLite pragma harness, the incremental-apply gap, and `goose.Up` replacing a hand-rolled blob. Per-package throwaway databases mean a test that passes because of state another test left behind now fails instead.\n\n---\n\n**Work-By:** Priya Nandakumar (05 Data Ops lead, Claude Opus 5) — CockroachDB review of the TestMain isolation approach against `multi-db-strategy.md`.\nEOF\ngh pr comment 49 --body-file /tmp/claude-501/pr49-review.md 2>&1 | tail -1",

- No general SLO/error-budget policy or alert catalog beyond the one retention-sweep alert rule this story requires.
- No re-derivation of the never-log list's 11 items or their categorization — that's `handoff-04-secrets.md`'s inventory, already final; this story only confirms and enforces it.

## PO review script

1. Read the CI lint-check config/rule directly; confirm it actually flags the named patterns (whole-struct log calls, never-log-list field names) rather than being a no-op placeholder.
2. Confirm the ingress `ConfigMap`'s log-format override is applied to the live ingress (not just committed in a manifest never deployed) and that a live search request's `name`/`phone` query params don't appear in the ingress access log.
3. Confirm the audit-log RBAC `Role` is genuinely distinct from Secret-read RBAC — read both role definitions, confirm no overlap, confirm the incident-review group binding.
4. Confirm the three sweep metrics reach the real sink (query the sink directly for `oldest_surviving_row_age_seconds`, don't just trust the code emits it) and that the alert rule is configured with the real numeric retention windows and real sweep interval substituted in, not placeholders.
4a. **Added per Tobias's objection — value correctness, not just presence:** seed one row of known age in each retention class, run the sweep once, query the sink for that class's `oldest_surviving_row_age_seconds`, and confirm the value is within a few seconds of the known seeded age — not merely that a number arrived. Neither side's criterion above checks the emitted value against ground truth on its own; this step closes that gap without duplicating either team's enforcement site.
5. Confirm 03's never-log-list enforcement test exists, runs in CI, and genuinely fails if a seeded sensitive value leaks into captured log output (mutate the test locally to confirm it can fail, not just that it currently passes).
6. Confirm Marcus's never-log-list completeness confirmation is recorded, and read it against the 11-item list directly rather than trusting a summary — including items 10–11, per the source-doc-drift note above.
7. Confirm Priya's ruling on the alert-formula question above is recorded, and that the alert rule matches whatever she rules (two-term formula as-is, or a third grace term) and that the skip-vs-dead suppression logic is actually wired in, not just designed.
8. **Rewritten per Tobias's objection — the original "suspend and wait one sweep interval" step assumed a short enough interval to observe live within a review session, but nothing in this story or LT-44 states the CronJob's actual schedule (plausibly daily, given the 24-month/30-day/7-day retention regime).** Cite the real schedule value here once Theo's manifest sets it; if it's longer than a review session can wait out, substitute a manually-triggered, off-schedule one-off `Job` run (bypassing the CronJob's own cadence) as the equivalent live proof that a dead/stopped sweep produces no other symptom and the alert correctly fires once its condition is met.

## Research team review

**Desmond Okafor — claims check:** Verified the `observability.md`/`handoff-04-secrets.md`/`LT-44.md`/`backlog.md` claims directly. One real finding: `observability.md`'s "operationalized" section and `backlog.md`'s own Story 5 text both still say "nine items," predating the F50 consistency-pass fix that brought the never-log list to eleven — neither was back-propagated. Not this refinement's error (it correctly uses eleven), but both source docs need Theo's fix. Everything else — the alert formula, `Drained`-only gating, the 11-item count and items 10/11's content, LT-44's metric names/class labels/`Forbid` — verified accurate.

**Tobias Lindqvist — objection:** Two real gaps. First, the alert as originally scoped can't distinguish a skipped run (from `Forbid`) from a dead sweep — a skipped run means no new metric line at all for that cycle, so the alert reasons about a stale prior value with no stated staleness handling; LT-44's own skip-visibility fix (5a) needs to actually feed this alert's suppression logic, not sit unused. Second, PO-script step 8 assumed a sweep interval short enough to observe live, but the actual schedule is never stated and is plausibly daily — untestable as originally written. Also flagged that neither side's metrics criterion checked the emitted *value* against ground truth, only that a number reaches the sink. All three fixes applied: the skip-vs-dead suppression requirement added to the 04-side criteria and Priya's question, step 8 rewritten to allow a manual off-schedule trigger, and a new step 4a (seed known-age rows, verify emitted value matches).

**Naomi Voss — ruling:** All fixes from both reviewers applied. This refinement is accepted and ready to hand off, with two flagged items outside this story's own scope: (1) Theo needs to fix the nine→eleven drift in `observability.md` and `backlog.md` directly — not this refinement's job to silently correct another track's source docs; (2) Priya's ruling on the alert-formula question remains genuinely open and must be recorded before this story can be called Done, not before it's handed to engineering to start building the parts that don't depend on her answer (the lint check, ingress redaction, RBAC, and metrics-exposure work can all proceed in parallel).

Work-By: Naomi Voss (PO, refinement + fix incorporation); Desmond Okafor (claims check, source-doc drift finding); Tobias Lindqvist (skip-vs-dead alert objection, PO-script feasibility objection, value-correctness gap).
=== sweep schedule if set ===
04-infra-devops/refinement/LT-49.md:29:- [ ] The alert rule `oldest_surviving_row_age_seconds{class="X"} > (retention_window_seconds + sweep_interval_seconds)` is configured per class in 04's actual alerting stack (not just theoretically derivable from the metric) — enforcement site: the alert-rule config file/CRD, with the real numeric retention windows (24 months/`direct`, 30 days/`idp_cache`, 7 days/`idp_cache_orphan`, per LT-44/`pii-governance.md`) and the real `sweep_interval_seconds` (the CronJob's own schedule, LT-44's manifest) substituted in, not left as placeholders.
04-infra-devops/refinement/LT-49.md:30:- [ ] **Added per Tobias's objection:** the alert's suppression logic distinguishes a *skipped* run (LT-44's `concurrencyPolicy: Forbid` causing the next scheduled run to be skipped when the previous one is still active — itself required by LT-44 5a to be visible in observability) from a genuinely *dead* sweep. With `Forbid`, a skipped run means no new `oldest_surviving_row_age_seconds` line is emitted for that cycle at all — the alert reads the previous run's last value, and whether that's distinguishable from a truly stopped sweep depends on the sink's staleness/retention handling, which nothing in this story or LT-44 currently pins down. Enforcement site: either (a) the same alert rule additionally suppresses/qualifies on LT-44 5a's skip-visibility signal, or (b) a distinct alert exists for "sweep skipped, still healthy" vs. "sweep dead" — LT-44's own fix (Forbid + skip-visibility metric) must actually feed the one alert it was built to inform, not sit unused.
04-infra-devops/refinement/LT-49.md:49:**Added per team-lead's routing, sharpened by Tobias's objection:** Priya Nandakumar (05) has a seat specifically on whether the alert formula's two terms are the right ones, since she owns the retention-window numbers and the sweep-invocation cadence assumption. Question for her turn: does `retention_window_seconds + sweep_interval_seconds` need a third term — a slack/grace factor for a sweep run that's merely running slow (not dead), given LT-44's `concurrencyPolicy: Forbid` means a slow run causes the *next* scheduled run to be skipped rather than overlapped? Tobias's pass confirmed this is worse than a "might trip early" edge case: a skipped run means no new metric line is emitted for that cycle at all, so the alert is reasoning about the previous run's last value, and whether that reads as "climbing" or "stale-but-fine" depends on sink staleness handling nobody has specified. This is why the 04-side criterion above now requires the alert to actually consume LT-44 5a's skip-visibility signal — Priya's ruling should say whether a third grace term is *also* needed on top of that, or whether skip-visibility alone resolves it.
04-infra-devops/refinement/LT-49.md:68:8. **Rewritten per Tobias's objection — the original "suspend and wait one sweep interval" step assumed a short enough interval to observe live within a review session, but nothing in this story or LT-44 states the CronJob's actual schedule (plausibly daily, given the 24-month/30-day/7-day retention regime).** Cite the real schedule value here once Theo's manifest sets it; if it's longer than a review session can wait out, substitute a manually-triggered, off-schedule one-off `Job` run (bypassing the CronJob's own cadence) as the equivalent live proof that a dead/stopped sweep produces no other symptom and the alert correctly fires once its condition is met.

A single skip and an endless run are indistinguishable by the presence of a skip signal; they differ only in how many consecutive intervals produce no fresh sample.\n\nThis is the same error as alerting on the mechanism rather than the property. The property is *\"is data surviving past its retention window, and is the sweep still reporting?\"* — neither of which is answered by \"was a run skipped.\"\n\n### The three rules\n\nLet **W** = the class's retention window, **I** = the CronJob interval, **D** = a sweep run's duration.\n\n**1. `RetentionSweepNotReporting` — per class.** Fires when no fresh `oldest_surviving_row_age_seconds` sample for that class in **more than 2I**.\n\nA single skip produces a gap of exactly 2I (sample at *t*, next at *t*+2I), so it does not fire — that is the grace for the case this question is about. Two consecutive skips produce 3I and it fires. A dead sweep fires. **This is the alert that distinguishes skipped from dead, and it does so without consuming the skip signal at all** — by counting missed samples rather than by trusting an explanation.\n\n**Per class, not global**, because the sweep is per class by contract (`multi-db-strategy.md` §3c — `DeleteExpired(ctx, class, olderThan, maxRows)`, one class per call). A class whose step errors while the others succeed would keep the global series fresh and go silent unnoticed.\n\n**2. `RetentionWindowExceeded` — per class.** Fires when `oldest_surviving_row_age_seconds{class} > W + 2I`.\n\n**The third term is `2I`, not `I`.** One I is the legitimate lag — a row becomes eligible just after a sweep completes and waits a full interval for the next one, so a healthy system reaches W + I routinely and an alert at W + I fires on every normal cycle. The second I absorbs one skipped run. This assumes **D < I**; if D approaches I the sweep is not keeping up and rule 3 is the real signal.\n\n**3. `RetentionSweepSkipRate` — low severity, the early warning.** Fires when skipped runs exceed ~25% over a rolling day. **This is where LT-44 5a's skip-visibility signal is consumed** — as evidence in its own right, not as a suppression term on rules 1 or 2. It catches \"the sweep is completing but only just\" before either of the others trips.\n\n### Numbers, at I = 24h\n\nTheo substitutes the real interval; these are the values if the CronJob is daily.\n\n| Class | W | Rule 2 threshold (W + 2I) | Seconds |\n|---|---|---|---|\n| `idp_cache_orphan` | 7 days | 9 days | 777600 |\n| `idp_cache` | 30 days | 32 days | 2764800 |\n| `direct` | 24 months (730d) | 732 days | 63244800 |\n\nRule 1 threshold is **2I = 172800 s** for every class.\n\n**If I changes, rules 1 and 2 both change.** They are expressed in terms of I deliberately: a hardcoded 9 days silently becomes wrong the moment the schedule moves to twice daily or weekly. Prefer deriving them from one `sweep_interval_seconds` constant in the rule config over writing the arithmetic out.\n\n### One interaction that must not be \"fixed\"\n\n`oldest_surviving_row_age_seconds` is published **only from a `Drained` result** (`multi-db-strategy.md` §3c — the value is meaningless mid-sweep, when deletable rows remain by construction and the oldest survivor is old). So a sweep that runs but never drains — hitting `maxRows` every batch — emits **no valid sample**, and rule 1 fires.\n\n**That is correct behaviour, not a false positive.** A sweep that cannot drain is not keeping up, which is exactly what should alert. Do not \"fix\" it by publishing non-drained values: that would replace a true alert with a metric that reports a large age every run and trains everyone to ignore it.\n\n*Ruled by Priya Nandakumar (05 Data Ops lead).

3:**Product Owner:** Naomi Voss (01). **Research team:** Imogen Hale, Desmond Okafor, Tobias Lindqvist. **Engineering:** Renata Cole (03, sweep-invocation code), Theo Bergman (04, `CronJob` manifest + metrics sink); design inputs: Priya Nandakumar (05, retention windows/clocks/classes), Marcus Ilori (02, seat on subject-deletion audit trail if any).
9:Per team-lead: without this, the README (LT-43, correctly deferred to write last) would have to list PII retention as stubbed — at a company whose own product framing is PII minimization, that's a real, visible gap in the submission, not a cosmetic one. Desmond's LT-43 finding made the case concretely: `DeleteExpired`/`DeleteProfile` exist and are tested on the DAO composite, but nothing schedules or calls either method — a designed-but-not-operational control. This is roughly a half-day story (a `CronJob` calling a `--sweep` mode of the existing `api-service` image, bounded by the already-built `maxRows`, audited) that turns a stub line into a delivered one.
13:Not new DAO methods — `DeleteExpired`/`DeleteProfile` already exist on the composite (05's `multi-db-strategy.md` §3c) and are already tested (LT-38's conformance suite: `TestConformance_DeleteExpired_*`, `TestConformance_OldestSurvivingAt_*`, `TestConformance_Drained_*`, `TestConformance_DeleteWritesExactlyOneDeletionLogRow`, `TestConformance_DeleteExpired_AlreadyCancelledContextDeletesNothing` — all confirmed present during LT-42's full completeness sweep). This story is the **caller**: a scheduled invocation that loops per `RetentionClass` until drained, plus a subject-deletion request path, plus the health metric that tells 04 whether it's actually running.
15:**Mechanism (team-lead's recommendation, adopted):** a `CronJob` in `04-infra-devops`'s manifests invoking `cmd/api-service`'s existing image in a new `--sweep` mode (or a distinct small entrypoint, `03`'s call) — not a new binary, not a new image build, reusing what's already deployed.
31:- [ ] `DeleteExpired` is never called with a request-scoped context — the sweep's own job/scheduler context governs it. Enforcement site: the sweep invocation's context construction (the `CronJob`'s own pod lifecycle, not an inbound HTTP request), plus a test asserting an already-cancelled context returns before deleting anything (the DAO layer already has this test per LT-38; this story's own test confirms the *caller* doesn't accidentally pass a request-scoped one).

One `CronJob`, daily, at an off-round time — `17 3 * * *` (03:17 UTC) rather than midnight.** Nothing on the record stated an interval, and every number in the LT-49 alert ruling is expressed in terms of it, so it needs pinning before Theo writes either manifest.\n\n**Why daily.** The binding constraint is the *tightest* window, not the longest: `idp_cache_orphan` at 7 days. A daily sweep means a row can legitimately outlive its window by at most one interval — 1 day, 14% overshoot — and puts the `RetentionWindowExceeded` threshold (W + 2I) at 9 days against a 7-day window, roughly 29% slack. Both are proportionate. Going sub-daily (6h, say) would buy precision the windows themselves do not justify: they are **proposed POC defaults whose basis column reads *unknown — needs a product/legal ruling*** (`05-data-ops/pii-governance.md`), and tightening the sweep to hours against a number nobody has ratified is false rigor. Going weekly would be wrong in the other direction — `I` = 7d on a 7d window puts the alert threshold at 21 days, three times the window it is supposed to protect. Dead-sweep detection also falls out acceptably: `RetentionSweepNotReporting` fires above 2I, so a stopped sweep surfaces in about two days, leaving five days of margin before orphan rows are meaningfully overdue.\n\n**One schedule for all three classes, not three.** The `CronJob` makes three sequential `DeleteExpired` calls — `idp_cache_orphan`, `idp_cache`, `direct` — in one invocation. Each class is independently batched and transactional, so a run interrupted between classes leaves a consistent database and simply resumes next cycle. The reason to keep it single is the alert config: three schedules would mean three values of `I`, and every threshold in the LT-49 ruling would triple. **Keep `sweep_interval_seconds` a single constant** and derive the thresholds from it rather than writing the arithmetic out.\n\n**03:17 rather than 00:00** because midnight is where every other scheduled job in the world already is, and because an off-round time makes a date-boundary bug distinguishable from a scheduling bug when one eventually appears.\n\n**Three triggers to revisit, each with what it means:**\n\n- **The `idp_cache_orphan` window drops below ~3 days.** `I` must shrink with it — at W = 2d and I = 24h the alert threshold would be 4 days, double the window.\n- **`RetentionSweepSkipRate` fires.** That means run duration D is approaching I. Either shrink I or raise per-batch throughput; the skip-rate alert exists to surface this *before* the other two trip.\n- **The `direct` class starts dominating run time.** Three sequential calls in one Job means a slow 24-month sweep delays the 7-day one. At take-home data volumes this is irrelevant; if it stops being irrelevant, split the schedules and accept a per-class `I` in the alert config.\n\n*Ruled by Priya Nandakumar (05 Data Ops lead).

The sweep is a short-lived pod; the scraper is a long-lived one; they never overlap. **So the sweep's per-class result has to live somewhere `api-service` can read it, and that somewhere is a table.**\n\n```\nretention_sweep_run\n  id                   UUID PK\n  class                TEXT NOT NULL   ck_retention_sweep_run_class: 'direct'|'idp_cache'|'idp_cache_orphan'\n  started_at           TIMESTAMPTZ NOT NULL\n  finished_at          TIMESTAMPTZ NULL          -- NULL = started and did not finish\n  rows_examined        INTEGER NOT NULL DEFAULT 0\n  rows_deleted         INTEGER NOT NULL DEFAULT 0\n  oldest_surviving_at  TIMESTAMPTZ NULL          -- non-NULL only when drained\n  drained              BOOLEAN NOT NULL DEFAULT false\n  missed_slots         INTEGER NOT NULL DEFAULT 0\n```\n\n**Written twice per run, not once.** A row is inserted at start (`finished_at` NULL) and updated at completion. That is deliberate: it makes three outcomes distinguishable that would otherwise collapse. **No row** = the run never started (skipped by `concurrencyPolicy: Forbid`, or the schedule is dead). **Row with NULL `finished_at`** = it started and died. **Row with `finished_at`** = it completed. Writing only on success would make a crashing sweep indistinguishable from one that was never scheduled — the same three-states-in-one-null defect `secret_state` exists to prevent.\n\n**`skipped_reason` cannot be a column, and this is the one place the requested shape does not work.** Under `Forbid`, a skipped run **has no pod** — nothing executes, so nothing can write a row explaining itself. A `skipped_reason TEXT NULL` would be NULL on every row that exists, forever.\n\nSkips are therefore recorded by the *next* run rather than the skipped one: on start, the sweep compares the gap since the last `finished_at` for that class against the interval `I` and writes **`missed_slots`** — `floor(gap / I) - 1`, zero in the normal case. That makes the skip rate computable from this table alone (`sum(missed_slots)` over a rolling day against expected runs), which is what `RetentionSweepSkipRate` needs, without depending on Kubernetes event scraping.\n\n**Tying CHECK, named `ck_retention_sweep_run_drained`:** `CHECK (drained OR oldest_surviving_at IS NULL)`. `oldest_surviving_at` is meaningful only from a drained result (§3c), so a non-drained row carrying one must be **unrepresentable, not merely discouraged**. NULL *with* `drained` stays legal — that is an empty class, which is a real state.\n\n**Index** `(class, finished_at DESC)` — serves both reads: latest-per-class for the gauges, and the rolling-day scan for the skip rate.\n\n**Roles: no new grant.** The sweep writes and `api-service` reads, both with the existing **runtime** credential. All four operations are DML, and `ALTER DEFAULT PRIVILEGES FOR ROLE migrator … GRANT SELECT, INSERT, UPDATE, DELETE ON TABLES TO runtime` already covers tables the migrator creates from that point on — which includes this one, since the migration runs as migrator. Nothing in `04`'s initdb changes.\n\n**Migrations: three files, not `shared/`.** This is DDL, so it goes in `postgres/`, `cockroachdb/` and `sqlite/` per A5 — `shared/` is seed data only. Same per-engine type mapping as every other table (`TIMESTAMPTZ` vs `TEXT` RFC3339, `BOOLEAN` vs `INTEGER`), and identical constraint names across all three.\n\n**This table's own retention — it is not a `RetentionClass`.** It holds operational metadata and no PII, so it is outside `pii-governance.md` and acquires no retention clock there. But it must not grow without bound: the sweep deletes `retention_sweep_run` rows older than **30 days** at the end of each run. Thirty days comfortably covers the widest alert window (24h) and leaves a month of history for debugging; at three classes daily that is roughly 90 rows.\n\nTwo things that must not happen to it. **It must never be added as a fourth `RetentionClass`** — the classes are `user_profile` classes, and mixing operational metadata into the PII retention machinery would put a table with no data subject under a policy built for people. And **its cleanup must never write a `deletion_log` row** — that log is the audit trail for *PII* deletions with meaningful reason codes, and diluting it with routine metadata housekeeping would make the thing auditors read mostly noise.\n\n### Conformance assertions (§7) — three backends\n\n- The tying CHECK rejects `drained = false` with a non-NULL `oldest_surviving_at`, on every backend.\n- Latest-per-class returns the same row on every backend given identical inserts.\n- **Timestamp ordering survives the round trip.** This is the real cross-backend risk here: Postgres and CockroachDB store `TIMESTAMPTZ` natively, SQLite stores `TEXT`, and a `TEXT` timestamp only sorts chronologically if it is zero-padded, fixed-width and in a single offset. **Store RFC3339 in UTC with a `Z` suffix** — a local-offset or variable-width rendering sorts lexicographically into the wrong order on SQLite alone, silently, and \"latest run\" then returns the wrong row on exactly one backend. Assert ordering explicitly across a set spanning a month, not just a round trip of one value.\n- `missed_slots` defaults to 0 and is never NULL, so the skip-rate sum needs no NULL handling.\n\n## 3a.

The three alert rules are unaffected in substance, and gain a cleaner source:\n\n- **`RetentionSweepNotReporting`** keys on the age of the latest non-NULL `finished_at` per class — a genuine absence of rows, not a stale scrape.\n- **`RetentionWindowExceeded`** keys on `oldest_surviving_at` from the latest **drained** row; the table's tying CHECK (`drained OR oldest_surviving_at IS NULL`) makes a non-drained value unrepresentable rather than something the rule has to filter defensively.\n- **`RetentionSweepSkipRate`** becomes `sum(missed_slots)` over a rolling day against expected runs — **computable from the table alone**, with no dependency on scraping Kubernetes `CronJob` events, which is what LT-44 5a's skip-visibility requirement was reaching for.\n\nA third distinguishable state falls out that none of the three rules previously had: a row with a NULL `finished_at` means the sweep **started and died**, as opposed to never having been scheduled. Worth a low-severity rule of its own if Theo wants it — a crashing sweep and an unscheduled one need different fixes, and today both look like silence.\n\n*Ruled by Priya Nandakumar (05 Data Ops lead).

The column would be NULL on every row that ever exists. Skips are recorded by the *next* run as **`missed_slots`** — the gap since that class's last `finished_at`, over `I`, minus one; zero in the normal case. That also makes the skip rate computable from the table alone rather than from Kubernetes events.\n\n**Write the row twice per run, not once.** Insert at start with `finished_at` NULL, update at completion. That is what makes three outcomes distinguishable: no row = never started (skipped or dead); NULL `finished_at` = started and died; non-NULL = completed. Writing only on success makes a crashing sweep look identical to an unscheduled one — the same three-states-in-one-null defect `secret_state` exists to prevent.\n\n**Other specifics:** index `(class, finished_at DESC)` serves both the latest-per-class gauge read and the rolling-day skip scan. No new grant — sweep writes and `api-service` reads with the existing **runtime** credential, all DML, already covered by the `ALTER DEFAULT PRIVILEGES` on tables migrator creates. DDL in all three per-backend directories per A5, identical constraint names; `shared/` stays seed-only. The sweep prunes rows older than **30 days** at the end of each run — **not** as a `RetentionClass`, and **not** writing a `deletion_log` row, since that log is the PII audit trail and routine housekeeping would turn it into noise.\n\n**The conformance assertion I would write first, because it is the one that bites on exactly one backend:** timestamp *ordering* across the round trip. Postgres and CockroachDB store `TIMESTAMPTZ` natively; SQLite stores `TEXT`, and a text timestamp sorts chronologically **only** if it is zero-padded, fixed-width and in one offset. **Store RFC3339 in UTC with a `Z` suffix.** A local-offset or variable-width rendering sorts lexicographically into the wrong order on SQLite alone, silently — and \"latest run\" then returns the wrong row on one backend while both others look fine. Assert ordering over a spread of timestamps spanning a month, not a single-value round trip.\n\nOne bonus you get for free: a row with NULL `finished_at` means the sweep **started and died**, which is a state none of the three alert rules could previously see — today a crash and an unscheduled run both look like silence, and they need different fixes. I have flagged it to Theo as a candidate low-severity rule; no action from you beyond writing the row at start.",

I messaged Renata directly with the full column list when I wrote it, so she should be unblocked — if she is still waiting, the message went astray rather than the work. Headline: `retention_sweep_run`, row written **twice per run** (insert at start, update at finish) so *no row*, *NULL `finished_at`* and *non-NULL* distinguish never-started, started-and-died, and completed. **`skipped_reason` cannot exist** — under `Forbid` a skipped run has no pod, so nothing can write a row explaining itself; skips are recorded by the *next* run as `missed_slots`.\n\n## Rule 3's window — Theo is right, and the fix needs more than a number\n\n**Confirmed: rolling 7 days, fire at ≥2 skipped runs.** He is correct that \"~25% over a rolling day\" is structurally meaningless at `I` = 24h, where a day holds at most one run and the threshold can only be 0% or 100%. **That was my error** — I wrote rule 3 before pinning `I`, and did not revisit it when I did. Same pattern as the migration-order inversion: a dependent statement left pointing at an old assumption.\n\n**But widening the window alone does not restore what rule 3 was for.** It exists as the *early* warning — it should fire while the sweep still completes, before rules 1 or 2. At `I` = 24h a skip-count rule cannot do that: two skips spread over seven days already lets a row reach `W + 2I`, which **is** rule 2's threshold, and two consecutive skips reach `W + 3I` and trip it outright. So it fires *with* rule 2, not before. Any threshold low enough to lead it (≥1 skip in 7 days) fires on a single node restart and gets muted — which is worse than not having it.\n\n**So the early warning keys on duration instead**, and the data is already in the table A7 specifies:\n\n- **`RetentionSweepDurationApproachingInterval`** — low severity, fires when `finished_at - started_at` > **0.5 × I** on any run in the last 7 days. That is the genuine leading indicator: duration climbing toward the interval is *why* skips begin, and it is visible while every run still succeeds. At take-home volumes it should never fire — it is a canary for growth.\n- **`RetentionSweepSkipping`** — Theo's rule as widened, kept as the backstop for skips with non-duration causes (node pressure, failed pods, a suspended CronJob) that the duration rule cannot see.\n\nBoth stay non-suppressing on rules 1 and 2.\n\n**One line for Theo's rule file:** all four thresholds are functions of `I` — `2I`, `W + 2I`, `0.5I`, and the skip window which is `7I` and should be written as such. Deriving them from one `sweep_interval_seconds` constant rather than committing arithmetic is the direct lesson of this correction: what broke rule 3 was a hardcoded assumption surviving a change to the value it depended on.",

=== forward-looking language in my two docs ===
28:**Every number below is a proposed POC default pending a product/legal ruling.** One asymmetry belongs stated plainly rather than buried: GDPR Art. 5(1)(e) storage limitation is a **principle** — data kept "no longer than is necessary" — demanding a window someone justifies. It is not a number anyone can look up. So every basis below is either an engineering rationale or the honest word *unknown*. There is no third kind, and a citation implying a regulation supplies a specific duration would be a false statement in a client-facing document.
40:**The `deletion_log` table itself has no sweeper, and that is a named gap rather than an omission.** It is not in the table above because it would be a row nobody can act on. Two facts make it awkward in a way worth stating rather than tidying away:
99:**Why suppression-on-skip was rejected, and it is the important half.** A sweep that chronically overruns emits a skip signal every interval — so an alert silenced by the presence of a skip signal is silenced permanently, exactly when the sweep is failing hardest. The suppression mechanism would become the failure mode. A single skip and an endless run are indistinguishable by the *presence* of a skip; they differ only in how many consecutive intervals produce no fresh sample, which is what rule 1 counts.
105:The audit stream is the one row in the table above whose number points the other way, and conflating the two kinds would be a real error rather than a pedantic one: apply minimization thinking to an audit trail and you delete the evidence.
