Closes#3279. Undoes the damage my #3261 did, now that #3277 has landed
and made it safe.
## What went wrong
#3277 established that last night's "future-dated" stamps were
**correct** — the author's local date in a UTC+1 container, written
minutes before their commits. The gate compared against the runner's
local calendar (PDT) and called them tomorrow.
I diagnosed it as author error and repointed seven stamps to turn main
green. The values I wrote were **neither the author's local time nor
UTC** — invented times chosen to satisfy a broken check. The FNXC record
is this project's why-does-this-exist trail, so those stamps misstated
when the work happened.
## Restored verbatim
| file | mine (wrong) | restored |
|---|---|---|
| `workflow-column-boundary-capacity.test.ts` | `22:30` |
`2026-08-01-00:30` |

| `workflow-column-boundary.ts` ×2 | `22:20` | `2026-08-01-00:20` |
| `workflow-graph-task-runner.ts` | `22:20` | `2026-08-01-00:20` |
## The check that mattered
Sequencing was deliberate — #3277 had to land first or this would have
re-reddened main. The real question is whether the gate now accepts the
**originals**, measured across the rollover boundary at local
`2026-07-31 17:23 PDT` / UTC `2026-08-01 00:23`:
```
America/Los_Angeles exit 0 Europe/Paris exit 0
UTC exit 0 Asia/Tokyo exit 0
```
`123 known future-dated stamp(s), none added`. **No baseline change
needed** — #3278's pruning already re-recorded `scheduler.ts`, and these
are known stamps rather than new ones.
Stamps only: `git diff` shows **zero** non-FNXC lines, 7 insertions / 7
deletions across 6 files. `census --strict` 0, `pnpm test:gate` 0.
## The part worth keeping
I argued against exactly this on #3263 — *"it rewrites stamps whose
authors are not us"* — and then did it myself six lines later, because I
was confident about a cause I had not checked. The commits' timestamps
were available the entire time; I read the runner's clock and never
asked what timezone the **author** was in.
Four of last night's seven PRs were fixing something that was not
broken. This is the cleanup for my share of that.
