NIGHTLY RUN DID NOT COMPLETE — marker stale (last date: 2026-08-04, today: 2026-08-06 IST)

## Details

- `nightly_marker.json` contents: `{"date":"20260804","exit_code":1,"finished_at":"2026-08-05T00:41:45+00:00"}`
- Expected marker date: `20260806` (today, IST)
- Marker is 2 days old — no run recorded for 2026-08-05 or 2026-08-06. Per protocol step 1, analysis stops here (no `nightly_20260806.json` was read).
- The last recorded marker also carried `exit_code: 1` (failure), finished 2026-08-05T00:41:45+00:00.
- This is now at least the fourth consecutive missed/failed marker night in a row (prior summaries flagged the same issue on 2026-08-03, 2026-08-04, and 2026-08-05 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 2026-08-05 or 2026-08-06 — 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.
