NIGHTLY RUN DID NOT COMPLETE — marker stale (last date: 2026-08-05, today: 2026-08-07 IST)

## Details

- `nightly_marker.json` contents: `{"date":"20260805","exit_code":1,"finished_at":"2026-08-06T00:40:29+00:00"}`
- Expected marker date: `20260807` (today, IST)
- Marker is 2 days old — no run recorded for 2026-08-06 or 2026-08-07. Per protocol step 1, analysis stops here (no `nightly_20260807.json` was read).
- The last recorded marker also carried `exit_code: 1` (failure), finished 2026-08-06T00:40:29+00:00 UTC (2026-08-06 06:10 IST).
- This is now at least the fifth consecutive missed/failed marker night in a row (prior summaries flagged the same issue on 2026-08-03 through 2026-08-06 runs, each finding a stale marker one day further behind).

## Action needed

Investigate why the nightly test cron (01:00 IST) has not produced a fresh marker for 2026-08-06 or 2026-08-07 — check whether the cron job is still scheduled/running and whether it's erroring before it can write `nightly_marker.json`. This is now a persistent, worsening pattern (not a one-off) and should be treated as higher priority than a single missed night.
