I read this as an authorized, one-shot production transaction - I’ll perform the read-only r71 preflight first, execute the immutable launcher exactly once only if every gate passes, then verify and write the required evidence.


The immediate gate found a production blocker: the latest immutable `observer-r70` row is `FAIL` (`first_day_status`), while Todo 10 requires its latest row to be `PASS`. I’m stopping before the launcher and recording the exact read-only blocker and zero-attempt evidence.


I read this as completing Todo 10 or returning an exact blocker - the mandatory preflight blocked execution.

**BLOCKED_PREFLIGHT**
- `observer-r70` latest row: `FAIL` (`first_day_status`)
- Cron latest run: `error`
- Launcher invocations: **0**
- r71 authorization, execution, runtime, and observer roots remain absent.
- No customer messages or updates occurred.
