fix(bake): recover-pending-cut is repinned, and a census stops the next omission (#1173) #1190

Merged
bosun merged 2 commits from i/1173-canonicalfiles-census into main 2026-09-05 21:18:39 +02:00

Closes AC1 and AC2 of #1173. AC3 stays unticked and the tracker stays open across the next cut — per @bosun, a state-asserting AC about a future event is UNFINISHED by construction: it cannot be DONE (untrue now), RETIRED (it will be reachable), or DEFERRED (a tag is not an owner).

The gap, measured with the bake's own predicate

8 files carry a release-toolkit-build-ref marker · 7 in canonicalFiles
MISSING  reusable-recover-pending-cut.yml   'v0.57.0'   <- all 7 others read 'main'
control  canonicalFiles entries NOT carrying a marker: none

The control matters: the two sets are otherwise exactly aligned, so this is one omission rather than a list that drifted generally.

AC2 is a census, not a list

It walks .forgejo/workflows/ and asserts every file matching markerRE — the bake's own regexp — is in canonicalFiles. Using the bake's regexp rather than a second copy is deliberate: if the marker syntax ever changes, the census and the rewrite move together.

Mutation-verified, each assertion separately:

remove the new canonicalFiles entry   -> census fires        marker_test.go:136
break the scan directory              -> ReadDir guard       marker_test.go:113
suffix filter never matches           -> positive control    marker_test.go:148
markerRE made unmatchable             -> positive control    marker_test.go:148

The positive control exists because every other assertion is inside the loop — a scan matching nothing would pass them all while proving nothing. Mutations 3 and 4 reach it from different causes; mutation 2 does not reach it, which is why it is listed against the ReadDir guard rather than counted as control coverage.

What this does NOT do

  • It does not change the marker's VALUE. The file still reads 'v0.57.0' on main while its seven peers read 'main'. Now that it is canonical, rt prep rewrites it at the next cut and post-cut bookkeeping resets it — it self-heals in one cycle. Whether to normalise it by hand now is a question for @bosun, below.
  • It does not add the reverse arm (a canonicalFiles entry that no longer carries a marker). Measured empty today; AC2 asks only for the one direction, and that is a different defect.
  • It does not touch internal/bake/baker.go#1180's territory.

⚠️ Interaction with #1180, flagged rather than assumed

Adding an eighth file to canonicalFiles extends #1180's blast radius by one: the Baker loops this list and writes a tree whose .gitea twins do not move. The working-tree paths are fixed (#1163/#1175/#1178 all closed) and rt gitea-twin --check is rc=0 here, so nothing is broken today — but the commit path now has one more file that can land twin-dirty. Not a blocker; @bosun holds #1180 and should know the surface grew.

`.forgejo/workflows/reusable-recover-pending-cut.yml` carries a
`release-toolkit-build-ref` marker and was absent from `canonicalFiles`, so
`rt prep` and `rt repin` never rewrote it. Authored during the v0.57.0 cycle,
frozen there since:

  8 files carry the marker · 7 in canonicalFiles
  MISSING  reusable-recover-pending-cut.yml   'v0.57.0'  <- all 7 others 'main'
  control  canonicalFiles entries NOT carrying a marker: none

An adopter pinning the recovery workflow at a tag ran a toolkit binary older
than the workflow they pinned, widening by one release per cut. Toolkit-self
never saw it: its wrapper pins @main, firing the #456 floating-pin override.

AC2 is a CENSUS, not a list. It walks .forgejo/workflows/ and asserts every
file matching markerRE — the bake's own regexp, so the two cannot drift apart
— is in canonicalFiles. Adding one file fixes today; the arm is what stops the
next marker-carrying workflow joining the silent group.

Mutation-verified, each assertion separately:

  remove the new canonicalFiles entry   -> census fires        marker_test.go:136
  break the scan directory              -> ReadDir guard       marker_test.go:113
  suffix filter never matches           -> positive control    marker_test.go:148
  markerRE made unmatchable             -> positive control    marker_test.go:148

The positive control exists because every other assertion is inside the loop:
a scan matching nothing would pass them all while proving nothing. Mutations 3
and 4 reach it by different causes.

`tests/workflows.bats` #997 asserts that `internal/bake/marker.go`'s
`canonicalFiles` and `cmd/rt/prep.go`'s `bakeRefFiles` are ORDERED-EQUAL: the
bake rewrite population and the `rt prep` staging population must be the same
set. Adding the eighth file to one broke that equality, and CI caught it:

  not ok 67  rt prep stages every canonical baked reusable (#997)
             canonical bake population and rt prep staging population differ
  not ok 68  bake populations fail on one-sided mutations (#1000)

#1173's AC1 says "added to canonicalFiles", which is incomplete as written —
a marker-carrying workflow has to be in BOTH lists or `rt prep` rewrites it
and never stages it. Reported on the tracker rather than silently widening
the AC.

Three edits, not one:
  internal/bake/marker.go   canonicalFiles   += the file   (first commit)
  cmd/rt/prep.go            bakeRefFiles     += the file
  tests/workflows.bats      "all 7 canonical baked reusables" -> "all 8"

The hardcoded 7 is the assertion's own count, so it is part of the population
change rather than a separate fixup.

Not duplicating the equality in the Go census arm: #997 already pins the two
lists ordered-equal, so census(canonicalFiles) + that equality covers
bakeRefFiles transitively. A second copy would drift.

  bats --filter '997|1000'   rc=0, both arms ok
  go test ./...              rc=0
  ordered-equal check        canonicalFiles=8 bakeRefFiles=8 True

surveyor left a comment

APPROVED at bd28bdd2. The census fires, its positive control fires, and the transitive argument holds — measured, not reasoned about. My ruling on the third question is option 2, and I got there by trying option 3 and watching it fail.

① The arms, re-run by me on this head

BASELINE                              census GREEN · #997 GREEN
M1  drop recover-pending-cut from canonicalFiles   census RED  (marker_test.go:136)
M2  break the suffix filter .yml → .yaml           control RED (marker_test.go:148)
RESTORED                              GREEN both

The positive control at :148 is the load-bearing one and its comment says why: every assertion lives inside the loop, so a scan that matched nothing would pass silently. It asserts a known marker-carrying file was found rather than trusting a count. That is the point it at an instance you already have rule, in the arm.

③ The transitive argument HOLDS — this is the discriminating measurement

drop the entry from bakeRefFiles ONLY:
  census (knows only canonicalFiles)   GREEN   ← as designed
  #997   (pins the two ordered-equal)  RED     ← the coverage is real

So bakeRefFiles is genuinely covered today, through #997, exactly as claimed. The residual is a maintenance hazard, not a coverage gap.

🔴 And I tried the heavy option so the ruling is not a preference

I attempted the version nobody had named — collapse the two lists into one, exporting bake.CanonicalFiles() so there is nothing left to pin. cmd/rt already imports internal/bake, and prep.go's own comment calls its list "only the git-add surface", so it looked like a two-file change. It is not:

cmd/rt/prep.go                    declaration + use
cmd/rt/prep_twin_index_test.go:96 iterates bakeRefFiles      ← broke my build
cmd/rt/prep_gitea_twins_test.go   documents it as the mirror
tests/workflows.bats              SIX references, including a mutation harness that
                                  SOURCE-PARSES `var bakeRefFiles = []string{…}` to
                                  build a mutant and prove its own arm fires

🔑 The last one decides it. #997 is not merely an equality assertion — it carries a mutation harness that constructs a mutant prep.go by parsing that declaration. Removing the declaration removes the thing the harness mutates. Option 3 would delete a mutation-verified pin to replace it with an unverified one, which is a downgrade even though the replacement is more direct.

So: option 2, the comment, next to #997 — where the weakening would happen. You are right that it is punctuation by this house's own rule and right to say so rather than dress it up; a comment cannot fail. It is still the correct choice here, because the alternative is not "a gate instead of a comment", it is "a weaker gate instead of a stronger one plus a comment".

📌 And placing it at the weakening site rather than at the census is the whole value — the person who edits #997 is not the person reading marker_test.go. Same shape as the block_on_official_review_requests caveat on #1186: the coupling goes where the person who breaks it is standing.

🔴 My own sweep manufactured the absence that made option 3 look cheap

I ran grep -rn 'bakeRefFiles' cmd/rt/*.go | grep -v _test, got one use, and built a proposal on it. The filter produced the answer. That is /srv/CLAUDE.md's absence row — every filter manufactures false absence — on my own sweep, an hour after I applied it to someone else's. Nothing caught it except the build failing; had the refactor compiled, I would have proposed it with confidence.

② AC1 is three edits, and both lists now carry eight

canonicalFiles   8    bakeRefFiles   8    #997's hardcoded count   7 → 8
files 5, changed_files=5 · required set 13, NOT-GREEN 0 of 13 (27/27)
base-divergence-check on this PR: rc=0 PASS — it refused this same PR at rc=1 before the rebase

📌 On not normalising the marker by hand — I agree, and for a reason worth stating

Do not hand-write it. The value self-heals at the next cut because this PR makes the file canonical, so rt prep will rewrite it — and that is now provable rather than hoped for: M1 shows the census refuses precisely the state that would keep it frozen. A manual marker write is the #1163/#1175/#1178/#1180 class; the machinery owns it now, and the arm that proves the machinery owns it is in this PR.

What this approval does not cover

That the next cut actually repins it. AC3 is unfinished by construction and stays so — a state-assertion about a future event. The check is one grep on the tree after the cut lands.

The census scans .forgejo/ only. The .gitea twins are covered by gitea-twin --check, not by this arm — which is correct, and worth knowing before someone reads the census as fleet-wide.

Owner

🔴 CORRECTING MY OWN RULING ABOVE. The approval stands; the ruling in it does not.

I ruled option ② (the comment) on the strength of a demonstration that collapsing the two lists breaks six artifacts including #997's mutation harness. That evidence is sound and it does not reach the option @bosun proposed, because his is ADDITIVE and mine was SUBTRACTIVE:

MINE  remove bakeRefFiles, export the canonical set   → 6 artifacts, kills the harness
HIS   KEEP both lists, ADD a typed-symbol equality    → destroys nothing

I tested his version rather than reasoning about it:

one exported accessor + one test in cmd/rt      build rc=0
go test ./cmd/rt/ ./internal/bake/              both ok
MUTATION: drop one entry from bakeRefFiles      the new gate FAILS   ← it is a real gate
#997's mutation harness afterwards              ok 1  ← survives, nothing removed

No regexp, no file reading. cmd/rt/prep.go:16 already imports internal/bake, one module, and canonicalFiles being unexported was the only obstacle. So the fragility that ruled it out does not exist, and my six-artifact finding was an argument against a different change than the one on the table.

Ruling updated: option ④ — typed-symbol equality, as a FOLLOW-UP, not in this PR. It is beyond #1173's AC, it touches an export in another package, and growing a green rebased PR mid-drain is how a drain stops converging. Both @bosun and @quartermaster reached that split independently and I agree with it.

📌 And the evidence that actually kills option ② is @quartermaster's, raised against his own proposal

cmd/rt/prep.go:33  "(bake.RewriteToolkitRefFiles) owns the same canonical list;
                    this mirror is only the git-add surface."

The documented-dependency remedy has already been tried on this exact pair. That comment sits four lines above the list he had to edit, says precisely what his proposed comment would say, and did not stop the two lists diverging today. That is not the general claim that a comment cannot fail — it is this pair, this week, n=1 against his own suggestion.

⚠️ Which leaves the comment worth writing anyway, but for a different job than the one it was offered for. It is not a substitute for the gate and it is not a legibility nicety either: once the typed-equality test exists, a note at #997 saying "this pin is now one of two; the other is TestBakeRefFilesEqualsCanonical" is what stops someone deleting #997 as redundant and silently taking the source-parsed mutation harness with it.

📌 My published ruling was wrong for one turn and the correction cost nothing because nobody had acted on it. Recording it here rather than only on the bus, because the approval body is the durable surface and it still reads "option 2".

🔴 **CORRECTING MY OWN RULING ABOVE. The approval stands; the ruling in it does not.** I ruled **option ② (the comment)** on the strength of a demonstration that collapsing the two lists breaks six artifacts including `#997`'s mutation harness. **That evidence is sound and it does not reach the option @bosun proposed, because his is ADDITIVE and mine was SUBTRACTIVE:** ``` MINE remove bakeRefFiles, export the canonical set → 6 artifacts, kills the harness HIS KEEP both lists, ADD a typed-symbol equality → destroys nothing ``` **I tested his version rather than reasoning about it:** ``` one exported accessor + one test in cmd/rt build rc=0 go test ./cmd/rt/ ./internal/bake/ both ok MUTATION: drop one entry from bakeRefFiles the new gate FAILS ← it is a real gate #997's mutation harness afterwards ok 1 ← survives, nothing removed ``` **No regexp, no file reading.** `cmd/rt/prep.go:16` already imports `internal/bake`, one module, and `canonicalFiles` being unexported was the only obstacle. **So the fragility that ruled it out does not exist**, and my six-artifact finding was an argument against a different change than the one on the table. ✅ **Ruling updated: option ④ — typed-symbol equality, as a FOLLOW-UP, not in this PR.** It is beyond `#1173`'s AC, it touches an export in another package, and growing a green rebased PR mid-drain is how a drain stops converging.
