Buyer outcome

Demo Analyst can start a Pending lineage run on the live PostgreSQL stack without
the Python/PostgreSQL write-clock race rejecting a valid event. Existing
installations and fresh installs now share the same trigger contract, and the
near-boundary clock behavior is exercised against the additive upgrade path.

Cause and fix

The 0018 BEFORE INSERT trigger overwrote recorded_at with
clock_timestamp() after Python captured occurred_at. On the live stack,
Python can be slightly ahead, so the check failed even though occurrence was
the earlier event in application order.

  • Stamp recorded_at := greatest(clock_timestamp(), occurred_at).
  • Reject client timestamps more than one minute ahead of the database clock.
  • Do not clamp occurred_at down; that would break monotonicity against
    previously stored Python-ahead status events.
  • Discard client-supplied recorded_at; the 2099 overwrite contract remains.
  • Keep the trigger body identical in the additive migration and baseline
    migration.
  • Apply migration 0030 in the real PostgreSQL test fixture after 0018
    and validate 5-second, 59-second, exactly-one-minute, and two-minute
    boundaries through that upgraded existing-volume path.

Stack and current head

This PR is safely stacked on #327's current branch
fix/searxng-corroboration-token-precision at base
e6ef7cc53bcfef1e3dd61705b9ab243251860730. The exact current head is
f9c53e7c18a696260d60bfcdd7c0af5e07c1dda6.

Claude found no correctness, security, data-loss, or auth defect. CodeRabbit's
valid upgrade-path finding was fixed in the current head; the earlier
20-millisecond assertion concern was made deterministic with a five-second
offset and equality assertion.

Validation

  • uv run --locked --extra dev --extra backend python -m pytest -q -> 578 passed, 16 skipped, 4 warnings
  • status-write clock boundary tests -> 5 passed
  • git diff --check -> passed
  • the full suite includes the fix: require complete organization token corroboration #327 relation-verification token-boundary fix

Independent formal approval and all required Checks on this exact head remain
mandatory. Do not self-approve or merge around a pending gate.

Stamp recorded_at as greatest(clock_timestamp(), occurred_at) so live
PostgreSQL no longer rejects occurred_at <= recorded_at when Python's
clock is ~15-20ms ahead. Do not clamp occurred_at down. Additive 0030
for existing volumes; 0018 for fresh installs (ADR 0013 follow-up).

@opencode-agent please review exact current HEAD 4d267ef. Required verdict: findings or explicit no-findings on this SHA only. This is the independent-on-main write-clock clamp (v2.12.6); not mixed into #258/#323. Formal APPROVE must come from a collaborator other than seonghobae. Do not self-approve.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: 🟡 Moderate · up to a6f39

The database timestamp trigger change remains blocked from merge by a failing full-suite gate, and the existing-install migration's new clock boundaries still lack direct test coverage. The prior risk of accepting arbitrarily future client timestamps is addressed by the one-minute limit.

Addressed the valid CodeRabbit finding in follow-up commit 80f44f65.

  • Both fresh-install migration 0018 and additive migration 0030 now capture one database clock reading, reject occurred_at more than one minute ahead with analysis_run_status_time_too_far_in_future, and otherwise persist recorded_at = greatest(database_now, occurred_at).
  • The Python-ahead integration test now uses a 5-second offset and asserts equality, making the branch deterministic.
  • Added a PostgreSQL regression test for an unbounded future occurrence.
  • Updated ADR 0013 with the bounded clock-skew contract.

Local evidence on the exact PR base plus this fix:

  • registry schema tests: 20 passed
  • full backend: 558 passed, 17 skipped
  • Ruff and git diff --check: passed

Current pushed head: 80f44f65.

Review exact current HEAD 4d267ef: the current source already includes the CodeRabbit future-time safeguard (one-minute bounded skew via database_now, raising analysis_run_status_time_too_far_in_future) and a live-registry edge test; focused test result: 3 passed, 17 deselected. The earlier arbitrary-future concern is therefore addressed on this SHA; no additional code patch is justified from that finding.

Required next actions remain: rerun terminal Checks after the latest head, obtain a formal independent approval, and verify the exact head again immediately before any protected merge. Do not self-approve or treat local evidence as hosted proof.

Review exact current HEAD 80f44f6: the latest concurrent patch now explicitly bounds future occurred_at to one minute, rejects analysis_run_status_time_too_far_in_future, and keeps the Python-ahead path. Focused registry tests: 3 passed, 17 deselected. The earlier CodeRabbit concern is addressed on this SHA.

Hosted Checks are queued; obtain the independent formal approval and re-check this exact SHA before any protected merge. No self-approval or release claim.

🟡 Two changelog entries share the same release number

A new changelog entry is added under version 2.12.6 dated 2026-08-21 (CHANGELOG.md:9) even though a different 2.12.6 entry dated 2026-08-20 already exists just below it, so the release history now lists the same version twice with different dates and contents.
Impact: Readers and any tooling that keys off version numbers cannot tell which 2.12.6 is which, and the release ordering becomes ambiguous.

Duplicate SemVer heading in CHANGELOG.md

The file header (CHANGELOG.md:3-5) states the project follows Keep a Changelog and Semantic Versioning, which require unique version entries. The diff inserts ## [2.12.6] - 2026-08-21 at CHANGELOG.md:9 while retaining the pre-existing ## [2.12.6] - 2026-08-20 at CHANGELOG.md:27. The new fix is a distinct release from the prior 2.12.6 and should carry a new version (e.g. 2.12.7).

Prompt for agents
CHANGELOG.md now contains two '## [2.12.6]' headings (one dated 2026-08-21 added by this PR at the top, and the pre-existing one dated 2026-08-20). Keep a Changelog / SemVer require unique version entries. Bump the new entry to the next patch version (e.g. 2.12.7) and update all corresponding references (CHANGELOG.d filename, ADR/AGENTS/CLAUDE 'v2.12.6' mentions) to the chosen version so the release history stays consistent and unambiguous.

🟡 New database migration reuses an already-taken sequence number

The new migration file is numbered 0030 (migrations/0030_analysis_run_status_write_clock.sql:1), but a different migration 0030_report_project_grouping.sql already occupies that same number, so two unrelated migrations now share sequence 0030.
Impact: The migration sequence is no longer a unique ordered series, which is confusing to maintainers and will collide once the planned migration ledger (keyed by number) is introduced.

Migration numbering collision

migrations/ already contains 0030_report_project_grouping.sql. The additive fix is added as a second 0030_* file. The current docker/postgres-init/migrate.sh (see the comment about replacing the 0012 gate with a migration ledger) applies every .sql by glob in lexical order and both files happen to be idempotent, so it works today. But a future ledger that records applied migrations by their numeric prefix would see a duplicate key, and the non-monotonic numbering obscures apply order. Choosing the next free number (e.g. 0104) avoids the collision.

Prompt for agents
The new migration file migrations/0030_analysis_run_status_write_clock.sql reuses sequence number 0030, which is already taken by migrations/0030_report_project_grouping.sql. Rename the new migration (and its rollback migrations/rollback/0030_analysis_run_status_write_clock.sql) to the next free, monotonic number (the highest current is 0103, so e.g. 0104). Update every reference to the old name: docker/postgres-init/Dockerfile COPY line, scripts/seed_demo_data.py, backend/tests/test_api.py, tests/test_analysis_run_registry_schema.py, tests/test_analysis_run_reconstruction_schema.py, and any docs that name the migration.

Exact head 3f8bb61 was updated to close the remaining raw TEPP provider-error path inherited by this stack. TeppClient and configured transport now return the stable unavailable error, with hostile provider regression tests; Ruff, 18 focused tests, compileall, and diff-check passed. Hosted checks and formal approval remain pending; no merge attempted.
