Delete branch "i/1173-canonicalfiles-census"
Deleting a branch is permanent. Although the deleted branch may continue to exist for a short time before it actually gets removed, it CANNOT be undone in most cases. Continue?
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
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 matchingmarkerRE— the bake's own regexp — is incanonicalFiles. 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:
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
ReadDirguard rather than counted as control coverage.What this does NOT do
'v0.57.0'onmainwhile its seven peers read'main'. Now that it is canonical,rt preprewrites 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.canonicalFilesentry that no longer carries a marker). Measured empty today; AC2 asks only for the one direction, and that is a different defect.internal/bake/baker.go— #1180's territory.⚠️ Interaction with #1180, flagged rather than assumed
Adding an eighth file to
canonicalFilesextends #1180's blast radius by one: the Baker loops this list and writes a tree whose.giteatwins do not move. The working-tree paths are fixed (#1163/#1175/#1178 all closed) andrt gitea-twin --checkisrc=0here, 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.🤖 Generated with Claude Code

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
The positive control at
:148is 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
So
bakeRefFilesis 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/rtalready importsinternal/bake, andprep.go's own comment calls its list "only the git-add surface", so it looked like a two-file change. It is not:🔑 The last one decides it.
#997is not merely an equality assertion — it carries a mutation harness that constructs a mutantprep.goby 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
#997is not the person readingmarker_test.go. Same shape as theblock_on_official_review_requestscaveat 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
📌 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 prepwill rewrite it — and that is now provable rather than hoped for:M1shows the census refuses precisely the state that would keep it frozen. A manual marker write is the#1163/#1175/#1178/#1180class; 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
grepon the tree after the cut lands.The census scans
.forgejo/only. The.giteatwins are covered bygitea-twin --check, not by this arm — which is correct, and worth knowing before someone reads the census as fleet-wide.🔴 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:I tested his version rather than reasoning about it:
No regexp, no file reading.
cmd/rt/prep.go:16already importsinternal/bake, one module, andcanonicalFilesbeing 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
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
#997saying "this pin is now one of two; the other isTestBakeRefFilesEqualsCanonical" is what stops someone deleting#997as 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".
