fix(cron): bind stale async-job cutoffs through the column encoder

[waleedlatif1]

Summary

• The stale-processing predicate in cleanup-stale-executions interpolated Date values directly into a raw sql template. A raw template carries no column context, so drizzle skips PgTimestamp.mapToDriverValue (which stringifies via toISOString) and postgres-js receives a Date it cannot serialize under the pools' prepare: false / fetch_types: false options
• Bind both cutoffs with sql.param(date, column), matching the workflow sweep already doing this on line 153 of the same handler
• The testing sql mock already rejected sql.param(date) for exactly this reason but not the interpolated form that shipped — extended it to cover both

Evidence

Every run of the job has failed its async-job sweep since v0.7.59, while the surrounding typed lt(column, date) sweeps in the same request succeed:

10:00:35.240 Stale execution cleanup completed <- lt(column, date) OK
10:00:35.287 Failed to clean up stale async jobs <- raw sql`…${date}` FAIL
10:00:35.431 Deleted 57 old async jobs <- lt(column, date) OK

• New: zero CleanupStaleExecutions errors in 7 days of logs before today; first at 09:00:35 UTC, the first run after the release cut over at 08:42:45
• Deterministic: 4/4 invocations since onset failed, every one immediately after its Starting stale execution cleanup job line
• Not data or environment: the identical predicate returns cleanly when run read-only with now() substituted; async_jobs has zero processing rows

Impact: stuck async jobs are never reaped, so job slots leak and executions stay running indefinitely.

Type of Change

• Bug fix

Testing

bunx vitest run app/api/cron — 15 passing. Reverting the fix with the mock guard in place fails 3 existing tests, so the regression is covered without new test code. Full suite (20,200 tests) shows no other route binding a bare Date into a sql template; the 5 unrelated failures reproduce on clean origin/staging. Lint 23/23 and typecheck clean.

⚠️ Correction (post-merge)

Independent verification after merge found two errors in the description above. The fix itself is correct and confirmed (reproduced locally against the real stack), but the recorded rationale is wrong:

1. The stated mechanism is wrong. This is not caused by the pools' prepare: false / fetch_types: false options — a 2×2 matrix test proved those are irrelevant. The actual cause is drizzle() overwriting client.options.serializers for temporal OIDs. The sql.param(date, column) fix is still the right one; only the explanation was incorrect.

2. The fix is incomplete, and the mock guard does not prove otherwise. Five further live instances of the same bug exist, one introduced in the same commit and release as the site fixed here. The claim that the full suite proved no other instances is false: the database.mock.ts guard only fires on paths tests actually execute, and 26 test files override the drizzle-orm mock — two of the missed sites have passing tests.

3. Realized production impact was effectively zero. No jobs happened to get stuck during the ~9.5-hour window. The bug was real and deterministic, but caused no measurable harm.

A follow-up PR addresses the remaining instances, corrects the misleading comment in packages/testing/src/mocks/database.mock.ts, and replaces the mock guard with a repo-wide detector that covers untested and mock-overriding code.

PR Summary

Low Risk
Narrow serialization fix in a cron cleanup predicate; aligns with an existing pattern in the same handler and restores behavior that typed lt(column, date) already uses.

Overview
Fixes the stale async job sweep in cleanup-stale-executions, which was failing every cron run because now and staleThreshold were interpolated directly into a raw sql template. Without column context, Drizzle skips timestamp encoding and postgres-js cannot serialize bare Date values under the app’s pool settings.

The handler now binds both cutoffs with sql.param(date, asyncJobs.startedAt), matching the workflow execution cleanup path in the same file. The testing createMockSql() helper also rejects interpolated Date values in sql templates, not only unencoded sql.param(date).

Greptile Summary

This PR fixes stale async-job cleanup by binding both Date cutoffs through the startedAt column encoder and strengthens the shared SQL mock to reject unencoded raw Date interpolation.

• Uses sql.param(date, asyncJobs.startedAt) in both stale-processing predicate branches.
• Extends the database test mock to detect bare Date values interpolated into raw SQL templates.

Confidence Score: 5/5

The PR appears safe to merge, with no actionable defects identified in the changed binding or regression guard.

Both cutoff values are now encoded through the matching timestamp column before reaching the database driver, and the mock detects the unsupported bare-Date form that caused the cleanup sweep to fail.

Important Files Changed

Filename	Overview
apps/sim/app/api/cron/cleanup-stale-executions/route.ts	Correctly routes both stale-processing cutoffs through the timestamp column encoder, consistent with the established sibling pattern in the handler.
packages/testing/src/mocks/database.mock.ts	Adds a targeted test-time guard against raw Date interpolation that mirrors the production serialization failure addressed by the route fix.
