Owner

Hardens account erasure so bounded encrypted identifiers and physical proof survive until every required store is verified. Covers persisted canonical_activity_id/evidence_activity_id aliases, nullable/direct ownership, request-owned snapshots, PeerDB paging, and the full 500-table/1 MiB fail-closed catalog contract. Selects the required shared analytics schema from 0178 and the guarded identifier migration 0179 individually.

User decision: implement safety before merge. User approval for the normal automatic production release after CI passes. These comments transparently transcribe the task responses. Final exact-head CI passed. The normal approved maintenance release is next; no bypass or manual production rollout.

The safety changes:

  • Actual sink callbacks acquire the existing durable publication owner before membership reads and keep it through terminal writes and acknowledgement; replacement consumers use the same owner.
  • Normal/local dbt, bounded repair/rollback builds and cycling publication use that owner. Native child admission remains nonterminal until the actual synchronous adapter, child exit and fresh selected-model artifacts agree. Unknown executor outcomes retain the barrier.
  • Frozen physical intent can replay only under safely admitted ownership, preserving original parts, schema and mutation evidence. There is no automatic crash clearance or new tracking framework.
  • Migration 0179 blocks unfinished legacy requests and now selects the existing maintenance deployment mode so old web producers cannot create uncaptured requests after its guard. Retained identifiers bind to their original credential key configuration. Final physical progress checks use the current database clock and roll back stale descriptor retirement atomically.
  • Physical absence queries batch exact database/table/hash tuples within the existing budgets, including inactive and projection parts. Root capture deduplicates with SQL UNION before encryption without combining identifier families.

Contains main 762b92d, including tiered storage, the shared quarantine correction and the cycling history fix. Main's six checkpoint fields and tiered/runtime hooks coexist with the newer request-owned and physical state.

Validation: exact 26.6 focused actual-writer/recovery qualification; exact 26.10 80/80 native cases (35 writer/owner/entrypoint, 40 erasure, 5 repair/rollback), all with retries disabled. The erasure matrix retains the 400k/800k-row resource case, aliases/ownership, frozen recovery, inactive/projection parts, survivors and metadata cleanup. Latest local checks also passed 58 real PostgreSQL store cases, affected units, root/server/web TypeScript and full lint/policy/SQL checks. Credential mutations: 48/48 killed. Root paging: 96.15%; transport positions: 97.37%, with only equivalent survivors and no exclusions. Evidence and retained diagnostic.

The final release review caught and fixed the missing 0179 maintenance marker. Stock classification changed from rolling to maintenance; 33 selector units, 10 real PostgreSQL cutover/capture cases and migration policy passed. This metadata-only change leaves the 80 native runtime results intact and requires a planned web availability interruption. The user explicitly approved that maintenance-window release after CI passes; the linked release decision record includes the exact response. The later current-main merge preserved both incident histories and the owned-client fixture: root TypeScript, 198 theCrag units and the strengthened native cycling-history/evidence/score case passed locally. Main’s final incident block remains at EOF to reduce further append conflicts.

Current head 8e7a6c5: CI 42711199875 passed: 109 successful jobs, five intentional skips and zero failures. Main 762b92d restores direct server deployment and independent mobile locking; its workflows and release documentation were inherited unchanged. Only the incident append conflicted; both histories are retained. Root TypeScript, changed-workflow actionlint, diff checks and the retained diagnostic patch check passed. Final conversation readback found zero unresolved threads; GitHub reports CLEAN/MERGEABLE and all required external checks passed. Earlier-head CI is historical evidence, not this head’s completed qualification.

Repeated read-only production preflight immediately before merge found zero cutover blockers, unfinished requests, retained user IDs/snapshots or unscrubbed rows under the exact 0179 predicate. Its locked migration guard still rechecks at execution time. After passing CI, merge is pinned to the checked head and the existing automatic release will be monitored. No manual production service update, acknowledgement, secret/key/offset change, historical identity scan, archive download or old-data retirement is authorized or performed.

Walkthrough

This PR adds staged account-erasure flow, request-scoped identifier storage, ClickHouse ownership and physical-proof checks, snapshot budget enforcement, and job/runtime wiring. It also updates database migrations, runbooks, and tests to match the new staged model.

Merge Risk: Moderate · previous review 316d1

This change hardens account erasure with bounded, encrypted identifiers and staged ClickHouse deletion. The author states the PR is not merge-ready. A concurrent writer can still republish erased data after the fence activates, and that risk should be resolved or explicitly accepted before merge. A few smaller lease, documentation and file-size issues also remain.

**Plan claims lack citations**

The plan states that migration 0179 belongs in scope, sets 500-table/1 MiB limits, and describes Q19’s authorization without linking primary sources that substantiate those claims. Readers cannot verify the extraction and release boundaries.

Link each claim to the relevant primary source, such as the migration, commit, or Q19 approval record, or remove claims that cannot be substantiated.

Pull Request Review Summary

Status: Blocked / Changes Requested

As noted in the PR description and documented in docs/evidence/erasure-extraction-20261108/, this PR is blocked and not merge-ready pending resolution of the raw sink republication race after earlier fence reads and synchronous erasure.


Key Findings & Architecture Audit

  1. Database Migrations & Schema:

    • drizzle/0178_native_metric_stream_delivery.sql and 0179_account_erasure_identifiers.sql correctly define the analytics query owner, stream state tables, and the fitness.account_erasure_identifier table.
    • Migration 0179 includes a runtime cutover lock and assertion (ERRCODE 55000) to guarantee that no unscrubbed or unconverted requests exist before establishing the identifier table.
  2. Bounded Identifiers & Storage Security:

    • src/account-erasure/identifier-store.ts enforces AES-256-GCM encryption (enc:v1:...) and SHA-256 digest hashing matching Postgres column check constraints.
    • Page sizes, wire/decoded byte bounds, and family limits in snapshot-budget.ts and clickhouse-identifier-pages.ts protect against unbounded memory consumption during identity closure discovery.
  3. ClickHouse Physical Erasure & Predicates:

    • Typed coverage inspection correctly distinguishes user-owned versus relation-owned physical tables and staging tables.
    • An inline issue was flagged on clickhouse-erasure.ts: array-cardinality string columns in boundedRelationPredicate evaluate expression without arrayMap, which would fail ClickHouse type checking (ILLEGAL_TYPE_OF_ARGUMENT) when calling SHA256 on an array.
  4. Merge Blocker:

    • The sink publication race demonstrated in docs/evidence/erasure-extraction-20261108/publication-race.patch must be addressed alongside sink/dbt publication coordinator alignment before this work can be merged into production.

Inline comments:
Review comments at
@docs/evidence/erasure-extraction-20261108/publication-race.patch:
- Line 37: Direct helper diagnostics do not verify behavior at the production
boundary; add acceptance tests that exercise the production event path through
handleEvents and verify both sink admission and erasure ownership. Keep the
existing diagnostic separate from those production-path checks.
- Line 42: Update the race diagnostic query using query_params so it also
verifies an unfenced user’s event remains queryable after the race. Add that
control event and assert it is present in the results, while preserving the
existing checks for the fenced user.

Review comments at @docs/production-incident-baseline.md:
- Around line 35694-35695: Update the “Final local result” claim to retain and
link the local qualification reports that substantiate the 180 catalog tests and
93.04% mutation score; keep the reported results verifiable from the cited
reports.

Review comments at @src/account-erasure/archive-erasure.ts:
- Around line 299-310: Update the archive matching predicates around
isMetricStreamDeletedEvent so references to retained group or alias UUIDs do not
cause events explicitly owned by another user to be removed; preserve explicit
ownership while continuing to match and remove identifiers belonging to the
erased account.
- Around line 306-310: Batch the activity membership checks in the archive
sweeps that use `identifiers.store.findPresent`: check activity IDs in bounded
groups and reuse each group’s results when matching events, rather than issuing
a lookup per event. Preserve streaming behavior by avoiding collection of all
foreign activity samples at once, and retain the existing user-ID and
null/undefined activity-ID matching behavior.

Review comments at @src/account-erasure/clickhouse-erasure.ts:
- Around line 181-188: Normalize userId to lowercase before passing it to
hashIdentifier in userPredicate’s mutationQueryParameters, so the mutation hash
matches ClickHouse’s normalized UUID representation; leave the logical predicate
and other behavior unchanged.
- Around line 168-175: Update captureColumns so the id of a ClickHouse
processing_operation root is captured as an operation identifier and included in
the operation closure, even when no other owned row supplies it; preserve the
existing identifier-column and identity-family captures.

Review comments at @src/account-erasure/clickhouse-physical-erasure.ts:
- Around line 445-450: Update the physical-erasure flow around
store.admitPhysicalIntent and owner.client.command so an admitted intent remains
recoverable if execution stops before DELETE submission, and retries can safely
resolve uncertain submissions. Establish and use a durable recovery protocol
that distinguishes unsubmitted work from completed or in-flight mutations,
retries submission when appropriate, and preserves the physical-deletion proof
required for account erasure.

Review comments at @src/account-erasure/identifier-store.ts:
- Around line 57-62: Update identifierKey and the identifier-store flow used by
findPresent to preserve or migrate retained identity keys when the credential
master key rotates. Ensure the migration also preserves the associated
identifier state, so existing rows remain discoverable after ciphertext
re-encryption and archive erasure can still match them.

Review comments at @src/analytics/analytics-query-owner.test.ts:
- Around line 540-543: Expand the test around describeAnalyticsDeliveryGroup and
analyticsDeliveryGroupIntentId to exercise cleanup against persisted PostgreSQL
descriptors rather than only the fixture’s clear record. Cover a valid
reservation, a missing descriptor, an insufficient high-watermark, and multiple
eligible descriptors; assert the persisted intent after cleanup in each case so
both descriptor-count and high-watermark checks are verified.

Review comments at @src/analytics/analytics-query-owner.ts:
- Around line 305-311: Update the command wrapper around clickhouse.command to
detect and propagate errors from the complete response before treating the fence
insert as successful, including when progress headers are enabled. Preserve the
existing query_id and async_insert settings.
- Around line 300-302: The ownership wrapper drains `result.stream` in the
`exec` response before returning it, so the callback cannot read the result
bytes. Update the owned `exec` handling around the `result.stream` loop to
preserve or replay every chunk for the callback while still waiting for EOF to
mark the terminal-request boundary.
- Around line 241-243: Update sink admission and account-erasure coordination
around the advisory lock in the query-owner flow so both operations share a
boundary that remains active through terminal ClickHouse writes. Ensure a
replacement cannot advance the drain while an earlier sink still holds a batch
that could be written after deletion; preserve the existing fence behavior while
establishing this write-lifetime guarantee.
- Around line 241-244: Update the advisory-lock acquisition flow around
session.query so a failed or timed-out lock request discards the session,
preventing a late backend lock from remaining active. Use the existing
session-discard mechanism, preserve propagation of the acquisition error, and
update the acquisition-failure test to verify the session is discarded.

Review comments at @src/db/account-erasure-processing.ts:
- Line 265: Update the lease renewal flow that checks lease_expires_at to
acquire the request row lock before evaluating expiry, and compare against the
current time after the lock is acquired rather than a timestamp captured before
waiting. Preserve the existing behavior for unexpired leases.

Review comments at @src/jobs/account-erasure-phase-runner.ts:
- Around line 122-124: Add safe recovery for legacy quarantine checkpoints in
the flow using quarantineHighWatermarksCheckpointSchema: when a checkpoint has
watermarks but no topic, recover the required per-route watermarks before
cutover so retention verification can succeed on retries. Establish and preserve
the correct route-to-watermark mapping rather than guessing or weakening
verification.

Review comments at @src/jobs/account-erasure-runtime.test.ts:
- Around line 224-230: Add a direct blank-brokers test in redpanda-drain.test.ts
that calls the production createAccountErasureRedpandaAdminFromEnv factory with
whitespace-only REDPANDA_BROKERS and verifies it throws the required error. Do
not rely on the runtime test’s mocked factory for this validation.

Review comments at @src/jobs/account-erasure-runtime.ts:
- Around line 211-228: Coordinate cycling-power inserts with account erasure by
having the publisher use the same analytics ownership boundary as
eraseClickHouse, identified by ANALYTICS_PUBLICATION_RESOURCE and
withAnalyticsQueryOwner. Hold that ownership through terminal ClickHouse
completion so physical verification cannot finish while an earlier insert is
still able to restore personal data; preserve the existing fence check.

Review comments at @src/jobs/process-account-erasure-request.ts:
- Around line 142-145: Update the AccountErasureSnapshotBudgetError handling
around markAccountErasureFailed to store a sanitized support-required reason for
snapshot admission failures. Ensure the status mapping returns that reason
instead of the automatic-retry message, without exposing last_error.

Review comments at @src/metric-stream/transport-position.test.ts:
- Around line 23-29: Update the transport rejection test using
metricStreamPositionSchema so it starts from the valid base fixture and changes
only transport to "pulsar". Keep other fields valid, ensuring the test
specifically checks the transport restriction.
- Around line 41-43: Add assertions around compareMetricStreamPositions that
verify numeric ordering across the decimal-width boundary: offset "9" must
compare before "10", and "10" must compare after "9". Preserve the existing
same-width ordering and equality assertions.

Session decision record, transcribed by the implementation agent from the user response in this task:

Question: “GitHub blocks merging until review conversations are resolved. For the documented safety gaps, should I implement the proposed fixes before merging, or record them as accepted limitations with follow-up issues after fixing the new routine review findings?”

User selection: “Implement the safety plan, then merge (Recommended)”.

This authorizes the documented offline implementation and normal PR merge after review and qualification. It does not authorize production operations. This comment records the task conversation; it is not a separate GitHub approval submitted by the user. Production auto-deploy is active, so that release boundary remains to be settled before a merge that would trigger production.

Follow-up to #3234 (review) (latest nonempty review body, including its credential outside-diff note):

  • The inline physical/store/runtime findings are fixed in a2d7d3b and c77cffd: fresh final lease checks with a real-PG RED→GREEN rollback test, exact-tuple batched retention proof, a cohesive root-page module, redundant-capture/seal-query cleanup, factory reuse and startup cleanup-failure coverage. All58store/database cases,78physical/runtime/dbt units and3paging units passed; four real26.6 recovery/projection/absence cases passed. Latest26.10 and CI qualification remain in progress.
  • Credential note: the concrete SDK provider and its factory are private. The only actual decryptValue caller is decryptCredentialValue, which still returns plaintext unchanged before constructing a provider. No second production caller or externally exposed provider instance bypasses it. The removed private plaintext branch duplicated this guarantee and was unreachable through the public API; reintroducing it for a hypothetical caller conflicts with the no-test-only-branches/minimum-code guidance. Public plaintext, authenticated-envelope/context and key-configuration behavior are tested. Fresh permanent-module mutation qualification killed48/48, zero survivors/uncovered. No public behavior or ciphertext format changed.
  • Approval and historical proof citations are explicit; the cleanup claims are qualified where original stdout was not retained. No production action is authorized.

Release authorization, transcribed from the user's latest task response:

Question: “The safety implementation is pushed and 80 exact ClickHouse 26.10 cases passed. Merging PR #3234 will trigger the active production deployment workflow, including migrations; your standing instructions prohibit production changes. Once CI passes, should I allow that normal production release when merging, or hold the merge?”

User selection: “Merge and allow the normal production release after CI passes.”

This supersedes the earlier production hold for the normal automatic release after this PR passes CI. It does not authorize bypassing checks, manual service updates, manual acknowledgements, old Kafka cutover packets or data-retirement actions. I will use the existing main-CI automatic handoff and monitor its selected revision and server release result.

Read-only production preflight (BEGIN READ ONLY / ROLLBACK, aggregate counts only) returned cutover_blockers=0, unfinished=0, user_ids=0, retained_snapshots=0, unscrubbed=0 for the exact 0179 predicate. The migration's table-lock guard remains authoritative at execution time. No production data or settings changed during this check.

Additional maintenance-window alignment, from the later task response:

After the missing cutover marker was found and fixed, the user was told that the existing maintenance mode interrupts web availability during quiescence and migration. The exact selection was “Approve the maintenance-window release after CI passes.” This authorizes the canonical maintenance path for this candidate after passing CI. It does not authorize an admin bypass, manual service mutation, old Kafka cutover packet or data retirement.

Merged as d21ce8f after exact-head PR CI (109 successful jobs, five intentional skips) and clear conversations. Main CI then passed (105 successful jobs, nine intentional skips). Automatic maintenance release 42719834571 completed server deployment at 23:47 UTC and OTA at 23:49 UTC; both migrations applied, consumers restored, and canonical CDC/Kafka/tiered/backup stability gates passed. No new native iOS archive was required.

Post-release verification found a real missed deployment dependency: owned live-sink publication fails with Postgres ECONNREFUSED because the sink stack has no DATABASE_URL override. The current task can appear healthy while idle; that is not proof of successful publication. Both web replicas run the merged revision, but consumer recovery is not yet established. The one-line shared deployment correction and incident record are in #3250; original/fixed stock rendering and YAML lint passed, and exact-head CI is running. No manual service update, offset, acknowledgement or secret mutation was performed.
