The old fixture ran the branch into the end of p1, so the T-patch lived
beyond the host (x>100) and the probe point [92,0] sat outside it under
any code behaviour: deleting the cutPartitionBody flatMap over patches
kept all subtests green (#188, found at the #132 code review).
The branch now meets the middle of the span, putting both node patches
inside the default opening's slot. The test proves its own fixture first:
an uncut run must show the patches bridging the slot, so if the geometry
ever stops producing them the control goes red instead of silently
devaluing the real assertion. Mutation-checked: reverting the flatMap
fails exactly this test, 888/889.

After the mandatory rebase of a published issue branch the pre-push hook
still passes remote_old..local_new, and once the old tip is no longer an
ancestor that range drags in the whole advanced dev history: on #117 it
meant 84 foreign commits and 20 false rule-8 rejections over already
closed issues, leaving --no-verify as the only exit.
The clamp lives in the gate rather than the hook: .githooks/pre-push
carries an executable bit that MCP publication strips (the commit-msg
precedent), so editing it needs an owner-side commit. When the target is
an issue branch and the declared base is not an ancestor of the head, the
base becomes the merge-base with origin/dev. Fast-forward pushes keep
their exact range, every own commit is still judged, and a real violation
in a post-rebase commit still blocks — covered by a scenario test that
goes red without the wiring.

On Windows URL.pathname yields /C:/..., which spawnSync then reads as C:\C:\...
and the whole npm test run dies in this one test. Linux CI never caught it
because both spellings coincide there — which is exactly why the canonical gate
lives on Linux and the local run is advisory.

The owner stopped using GitHub Projects. Most of this is wording, but one part
was not: release-prerelease.mjs talked to the Project in code. finishIssues
looked up the project id, listed its items and its Status=Done option, and threw
when an issue was missing from the board — so the first release that closed an
issue would have died on a step with nothing to do with publishing. Found by
reading rather than by releasing, which was luck.
Closing issues stays, and now strips the status label first. That order is not
cosmetic: the invariant that a closed issue carries no status label has broken
twice already, both times because a manual step did it the other way round. The
close-merged job already does it in this order.
The documents now say labels and only labels. The explicit "no longer used"
lines are kept on purpose, in PROCESS.md and next to the code that used to sync:
a decision that vanishes quietly gets reintroduced a month later by someone who
never knew it was made.

Five times in this project a green test meant nothing was checked. The
continuity smoke stayed green after the entire mechanism it guards was cut out.
The golden scene created to protect doorway light was empty — 1,177 warm pixels
against 107,119, all of them icons. The shadow smoke passed while no shadow was
drawn. Each time the test had been written alongside the code, went green at
once, and nobody ever asked whether it could go red.
The gate makes that question routine. Each mutant is a few lines of patch that
reproduce a known breakage, plus the name of the test that must fail on it. A
worktree is patched, the bundle rebuilt, the guard run — and a guard that stays
green fails the gate. Six mutants cover the holes documented in #85; the anchors
are exact strings from today's source, so the registry cannot silently drift —
a unit test that runs with the ordinary suite refuses a stale anchor.
The full run rebuilds the bundle per mutant, so it lives in its own workflow,
before a stable release and on a weekly schedule, not in Validate. The rules for
new tests are written at the top of docs/TESTING.md, and the sixth of them is
the cheapest: an assertion that reads back the property the code just set is
not written at all.
