Last loose thread from the 2026-07-31 stamp-repointing wave. Two comment
lines.
```
line 1027 ConcurrencyAdmission 2026-07-31-09:00 -> 2026-07-21-22:30 (eef5eb751e)
line 1471 WorkflowLifecycleColumns 2026-07-31-05:00 -> 2026-07-30-20:55 (109204c590)
```
## Not a revert — neither value was ever right
| stamp | originally | after #3280 | authoring commit (UTC) |
|---|---|---|---|
| `ConcurrencyAdmission` | `2026-08-06-09:00` (16 days ahead) |
`2026-07-31-09:00` (10 days late) | **2026-07-21 22:30** |
| `WorkflowLifecycleColumns` | `2026-08-01-05:00` (~1.5 days ahead) |
`2026-07-31-05:00` (~1 day late) | **2026-07-30 20:55** |
Both were written **ahead of their own commits** to begin with. Three
lanes then repointed stamps to turn `main` green (#3261, #3269, #3280),
moving the **date** back a day while keeping the clock time — which
converts an hours-off stamp into a days-off one in the opposite
direction. #3282 reverted the batch it owned; these two were outside its
scope.
So restoring the originals would be wrong too. The defensible values are
the authoring commits' UTC timestamps, per the `date -u` rule #3281
settled.
## Why now
`scheduler.ts` is a hot file. This survived two successive claimants — I
flagged it on #3262 and again on #3288 rather than opening a conflicting
PR, and said I'd take it once the file was unclaimed.
`check-file-claimed` now reports UNCLAIMED, so here it is.
## Scope
The gate is **green either way** — #3277 fixed the comparison, so
nothing is blocked by this. It is purely about the FNXC trail recording
when the work actually happened, which is the only reason the trail
exists. A stamp that satisfies a check while misstating the date by ten
days is worse than no stamp.
## Verification
```
check-fnxc-future-dates green
check-inert-sync-lane-conversions green
check-lane-wiring green
check-sql-column-literals green
census --strict green
