DottaandPaperclip d2e3f7dce5 fix(db): correct 0130 responsible-user backfill in place (inbox resurface) (#9111)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work
> - Users triage agent work through the issue inbox, which suppresses
archived issues by comparing issue `updated_at` against the archive
timestamp
> - Migration `0130_run_responsible_user_invariant` backfilled
responsible-user columns but also set `updated_at = now()` on every row
it touched (companies, issues, routines, routine_runs, heartbeat_runs)
> - That blanket timestamp bump made every archived issue look newly
updated, resurfacing thousands of archived issues into every user's
inbox
> - This pull request corrects the 0130 backfill in place so it only
fills `NULL` responsible-user columns and never touches timestamps, and
adds tests that prevent this class of bug from being reintroduced
> - The benefit is that inbox archive suppression stays intact across
migrations, and no future migration backfill can silently bump
`updated_at` on user-visible tables

## Linked Issues or Issue Description

**Bug description (no public issue exists):**

- **What happened:** after upgrading a dev instance across migration
0130, every previously archived inbox item resurfaced as unread/new for
all users.
- **Expected:** data backfills must not alter row modification
timestamps; archived issues stay archived unless genuinely updated.
- **Root cause:** the 0130 backfill's `UPDATE` statements set
`updated_at = now()` alongside the responsible-user columns.

## What Changed

- `packages/db/src/migrations/0130_run_responsible_user_invariant.sql`:
removed all `updated_at = now()` assignments from the backfill UPDATEs;
the migration now only fills `NULL` responsible-user columns. The file
is corrected **in place** (no new migration number, journal untouched)
because 0130 has never shipped in a published release.
- `packages/db/src/client.test.ts`: added a guard test that scans every
migration and rejects backfills that bump `updated_at` on user-visible
tables (with an explicit allowlist for the pre-existing 0131 repair
migration).
- `packages/db/src/client.test.ts`: added a replay test that simulates
an already-migrated database picking up the corrected file (deletes the
0130 ledger hash, re-applies mid-journal) and asserts issue `updated_at`
and inbox-archive suppression ordering are untouched.

### Why an in-place edit is safe

- 0130 only exists on master/canary builds; the latest published release
(v2026.626.0) predates it.
- The migration ledger is content-hash based: databases that already
applied the old 0130 keep an orphaned hash row (harmless) and see the
corrected file as pending, so they replay the corrected backfill — which
is idempotent (fills `NULL`s only, no timestamp writes).
- Fresh databases simply run the corrected 0130 in journal order.

## Verification

- `pnpm --filter @paperclipai/db run check:migrations` — clean
- `cd packages/db && npx vitest run src/client.test.ts` — 11/11 passing
against embedded Postgres, including the new guard and mid-journal
replay tests

## Risks

- Migration safety: the corrected backfill is idempotent and only writes
`NULL` columns; replay on already-migrated databases is exercised
directly by the new test. No schema changes.
- Databases that already ran the old 0130 keep the bumped timestamps
from that run; repairing historical damage is intentionally out of scope
here (no released build ever contained the bug).

## Model Used

- Claude Opus 4.7 (`claude-opus-4-7`, extended thinking, tool use) via
Claude Code / Paperclip agent runtime
