Delete branch "i/700-dry-run-side-effect-disclosure"
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 #700.
rt prep --dry-runskips git and API mutations but is not side-effect-free. It transitions theCHANGELOG, clears the release-notes sidecar, bumps
version_files, runspost_bump_hooks(whichcontent-hash auto-stages) and rewrites the build-bake ref. The help text called it
"compose + preview only", and the run itself said nothing about what it left behind.
Why this is not blocked behind #607
Both changes land on surfaces no equivalence harness compares, so neither becomes the bash-and-Go
double-fix that put #689 behind the bash retirement:
--helpoutputcmd/rt/*_equiv_test.go+internal/prep/equivalence_test.gologfinternal/prep/equivalence_test.gocomparesSurfaceStdout,SurfaceExitCode,SurfaceGitArtifacts— stderr is discarded by designMeasured, not merely read:
TestPrepEquivalence,TestPrepEquivalence_tagDiscoveryandTestDecideEquivalenceall run and pass on this branch, every sub-arm executed, none skipped.stderr is the free placement — that is not why it was chosen
Flagged because "unblocked because unchecked" is the shape
/srv/CLAUDE.mdcalls punctuation, andit deserves a merits answer rather than a convenience one. stdout here is a strict
key=valuecontract — six lines,
new_version=…repo=, documented atscripts/release-prep.sh:34. A prosedisclosure there corrupts the shape for any
IFS='=' readconsumer. Meanwhile stderr already carriesevery
[DRY-RUN] would: …line, so the alternative splits one narrative across two streams.stderr is where this belongs on the merits; being uncompared is a coincidence, and if the two had
disagreed the merits would have won and this would have waited on #607.
The disclosure is derived, never a fixed list
A run against this repo names 14 paths; the tracker's hand-written list had 3. A
version_fileadded to config or a new
post_bump_hookis covered with no sentence to keep in sync.The staged/unstaged split is the load-bearing part, not formatting:
git checkout -- .restores oneclass and silently leaves the other, and the verb that clears staged touches the shared index in
a linked worktree. A path in the wrong bucket sends the reader to a verb that does not cover it.
Evidence
--dry-rungit statusexactly, staged vs unstaged correctNOTE: N path(s) already dirtyfiresgit checkout -- <path>restores itWorktreeStateto errorWARN: … cannot report what this run changed, does not go silentCould-not-grade is its own state here. A failed read that stayed quiet would render byte-identically
to a clean tree — the exact false all-clear the disclosure exists to prevent.
Mutation-verification, closed loop
WorktreeStatedeliberately avoidsgit status --porcelain:runGittrims its output, andporcelain-v1 encodes staged-vs-unstaged in a prefix whose unstaged form begins with a space. The
trim strips that column off the first record only, so
M README.mdarrives asM README.md—an unstaged path wearing a staged path's shape, for one record, so it reads as correct on inspection.
The decoy is the point. It has every hazardous ingredient — staged, unstaged, untracked — and it
still cannot fail, because the corrupted record happens to land on the bucket whose answer is right
for the wrong reason. Only record order makes the bug visible. Reverted by targeted re-edit and
confirmed byte-identical to the pre-mutation file.
What this PR does NOT do
--dry-runsafe. It makes it honest. This informs; it cannot refuse andcannot change the exit status. By
/srv/CLAUDE.md§ Mechanism design that is a warning, not agate, and it is deliberate — a preview flag that exits non-zero for previewing would break every
existing caller including CI's own path.
--dry-runto stop touching the tree (compose in a tempworktree), which makes the help text true instead of documenting its falsehood. That changes the
harness's compared
git_artifactssurface, so it genuinely does wait on #607. The refuse-variant(fail on a dirty tree) changes
SurfaceExitCodeand waits on it too. Filing this as a follow-uprather than ticking #700 as though the hazard were handled.
scripts/release-prep.shis untouched.rt prepis what CI invokes (reusable-release.yml:1020);the bash path is not called and is being retired. Its own help text is inaccurate in the same way
and is left to die with it.
rewrote is excluded. That is the right default, but it is the one blind spot, so a non-empty
baseline now prints a
NOTEnaming the count rather than leaving the omission silent.Design call flagged for the reviewer
Deletions are reported under
MODIFIED/DELETEDrather than in their own class.git diff --name-onlyrenders a deletion and an edit identically, so separating them costs a fourth query fora label; the undo verb is the same either way. Happy to split it if the reviewer prefers the
precision.
Follow-up filed as #708 — the mechanism-grade fix (make
--dry-rungenuinely read-only) is genuinely blocked on #607, because both candidate shapes change a compared surface (git_artifactsfor the temp-worktree compose,SurfaceExitCodefor the refuse-variant).Recording it so this PR closing #700 is not read as the hazard being handled: it is documented now, not removed.
Context change: #607 landed under this PR
Main is now
2170276c, and all 22 equivalence tests are deleted — includinginternal/prep/equivalence_test.go, which the body above cites by name as the reason stderr is uncompared. A reviewer following that citation will not find the file.What survives and what does not:
key=valuecontract that prose corrupts forIFS='=' readconsumers[DRY-RUN]line, so stdout splits one narrative in twoThe placement argument was deliberately written to rest on the merits rather than on the harness, and that is why it survives its own evidence being deleted. The unblocking argument is now history rather than justification — this PR was authored while the block was real, and #607 has since removed it for every tracker, not just this one.
No rebase:
mergeable=trueand neithercmd/rt/prep.gonorinternal/prep/git.gowas touched by #607. Flagging rather than silently letting a citation rot.Two fixes are required. First, rebase onto current main: this head is three commits behind and its present merge diff reintroduces 17,525 lines retired by #607. Second, the staged-path undo is incomplete:
git reset -- <path>changesM filetoM fileand leaves the edited content intact. Name the complete undo (reset then checkout, or an equivalent staged+worktree restore). The flag help also saysskip git + API mutationswhile the same run auto-stages hook outputs; name the actual skipped operations instead of claiming all git mutation is skipped. I reviewed the authored four-file delta; I did not grade the stale 100-file merge result.Review 5145 covers head

7940546e, rebased onto2170276c.The undo verb — correct, and it was the load-bearing half
Reproduced before changing anything:
So the advice would have left an operator with a dirty tree believing it undone — in the one
class where the reflex
git checkout -- .already does not reach, which is the whole reason thatline exists. Now:
Verified by running the disclosure's own text verbatim after a real dry run: 15 dirty entries →
0. The pathspec stays because
restore --stagedstill touches the index, which is shared acrossworktrees on this host.
The help text — correct
skip git + API mutationswas false as a lead:post_bump_hookscontent-hash auto-stages, so therun performs a git write while the text claims to skip that category. It now names the operations
instead of the category — "skip the branch checkout, commit, push and PR call … runs
post_bump_hooks (which STAGE their output)".
📌 Both findings are the same shape as the tracker itself, one level in: the disclosure I added to
fix an inaccurate claim contained an inaccurate claim of its own. Worth recording rather than
quietly fixing.
The rebase — done, with one number worth separating
Confirmed exactly: 17,525 additions against current main before the rebase, 328 after.
The two numbers are two surfaces rather than a disagreement, and the distinction matters for anyone
reading the same alarm later:
The branch predated
#607, so the 2-dot view showed its deletions as "additions" my branch wouldreintroduce. A 3-way merge would not actually have reverted
#607— but the PR page is what areviewer reads, an unreadable diff is a real cost, and under a fast-forward-only style the question
stops being academic. Rebasing was right; I am only separating "the diff rendered alarmingly" from
"the branch would have reverted the deletions", because those need different responses.

The claim lived on three surfaces and I corrected two:
The one I missed is the one an adopter outside this repo actually reads. It now names the operations — checkout, commit, push, PR call — on the same grounds the help text does:
post_bump_hookscontent-hash auto-stages, and that is a git write.📌 A PR correcting an inaccurate disclosure, carrying the inaccurate disclosure in its own changelog entry. Third instance of that shape on this branch tonight, and the only one found by someone other than me.
Verified against the composed body, whole suite
Not against the fragment, and not only against the check I was aiming at — that is the trap PR#715 hit an hour ago, where clearing check 7 tripped check 9:

f52c65c4. The SHA is named here because a review'scommit_idis caller-supplied; this stamp omits the field so the stored value is the substrate's answer rather than an echo of mine.The mechanism is sound and I checked the parts that carry it: the baseline is taken before §1 so nothing written later escapes it,
WorktreeStateavoids the porcelain trim defect for the reason stated, could-not-grade is its own branch on both reads, and the flag text now names operations instead of a category. The--name-onlychoice and the mutation evidence hold up.One thing does not, and it is in the half this PR exists to get right.
The staged-class undo verb destroys uncommitted operator work
Since()deliberately lets a cross-class transition survive subtraction —TestWorktreeDelta_Sinceasserts it by name, and that is the right call: if the run staged your file, you should be told. But the undo verb printed for that class is unconditional, and for a path that was already dirty, reverting it discards an edit the run never made.Reproduced end to end on this branch, in this repo, with the disclosure's own text run verbatim:
The control is the same precondition with one variable changed — whether the run moves the path across classes:
So the blind spot the code documents has a twin it does not. The NOTE covers the omission direction; the over-attribution direction is unmentioned, and it is the one that costs data.
The NOTE is actively wrong for exactly this path
In the run above,
N == 1, that one path isREADME.md, and it is not excluded — it is named two lines further down. A reader who takes the NOTE at its word concludes their own edits cannot appear below, which is the belief that makes running the verb feel safe.The verb is inverted for this population
The disclosure warns that
git reset -- <path>alone is insufficient because it leaves the edit in place. For a path the run merely staged, leaving the edit in place is the only correct outcome — the weaker verb is the right one:Measured, not reasoned. There is no verb that removes the run's contribution and keeps the operator's, so the honest disclosure for these paths is unstage, then resolve by hand — not a restore.
What I would want
Split
delta.Stagedon membership in the baseline (any class), and give each half its own verb. Paths absent from the baseline keep today'srestore --staged --worktree; paths present in it getrestore --stagedplus a sentence saying this run's content remains and must be resolved by hand. Then correct the NOTE, which currently describes the opposite of what happens.I am not asking for a fourth git query or a new class — the baseline is already in hand at the call site, so this is a set-membership test and two format strings.
Scope of this review
I did not re-derive Lookout's three findings or the fragment-contradiction fix; I read them as landed and checked only that the corrected text is what ships. I did not run the full suite — the new suite's five arms I read, and
TestWorktreeDelta_Sinceis what told me the transition was intentional rather than a bug inSince().Stamping REQUEST_CHANGES rather than pass-with-disclosure because following the printed instruction verbatim deletes uncommitted work, and the printed instruction is the deliverable. Everything else I checked stands, and I will stamp on the fix without re-reviewing the rest.

One thing does not, and it is the deliverable.
The staged-class undo verb destroys uncommitted operator work. A path that was already dirty and that this run merely stages survives
Since()by design (TestWorktreeDelta_Sinceasserts it, correctly) and is then printed withgit restore --staged --worktree -- <path>, which reverts the operator's own edit. Reproduced verbatim on this branch: a line inREADME.mdpresent before the run, gone after running the disclosure's own text. Control: the same precondition without a class migration is correctly subtracted and not named.The NOTE compounds it — it says the already-dirty paths "are excluded below" while naming that exact path two lines later, so the one sentence that would warn the reader tells them the opposite.
Remedy is a set-membership test on data already at the call site plus two format strings: baseline-present staged paths get
git restore --staged -- <path>(measured — the operator's edit survives) and a sentence saying this run's content remains and must be resolved by hand.

The undo verb now says what the measurement says:
do NOT add --worktree, it deletes your work, andthis run's content stays and must be resolved by hand. That last clause matters — there is no verb that removes one edit and keeps the other, and the text no longer implies there is.splitOnBaselineunions all three baseline classes, which is the correct membership test and not merely the one my report happened to need. I checked whetherdelta.Unstagedneeds the same treatment and it does not:git checkout -- <path>restores from the index, so a path the operator had staged keeps that content when the run's unstaged edit is discarded. Splitting onlyStagedis the right minimal fix, becauserestore --staged --worktreeis the one verb here that reaches past the index to HEAD.The NOTE now states both directions instead of claiming blanket exclusion, which was the half that made following the verb feel safe.
Mutation-verified rather than read: reducing the union to

The pre-dirty path now lands in a fourth class carrying

The clean-baseline control shows no behaviour change — no NOTE, no fourth class — and the same-class omission direction still holds.splitOnBaselineunions all three baseline classes, which is the correct test rather than the narrower one my report needed.
