[Add] Pin the ticket move's conflicts to Git's, and word them by kind (#351) - #418

Conversation
…#351) Acceptance tests run seven three-way shapes through a real `git merge` and assert `mergeTree` names the same files, marker regions and conflict kinds; the patch flow's regions are pinned to the hunks `git apply --reject` rejects, with the two-way limit recorded as a characterisation. `parseMergeTreeZ` reads the `-z` informational records into `kinds`, threaded through `rebaseOntoTrunk`, main's branches handler and `rebaseRefusal`, which now words a refusal per kind instead of claiming "the same lines" for a deleted or a doubly added file. Self-review: 5 fix-here fixed (worktree cleanup that no-oped and leaked, side-less modify/delete wording plus the mirror fixture, prototype-safe kind lookups, two unpinned parser branches, the no-paths sentence); the follow-up on parsing Git's message is documented in the parser.

- Line 286: Update the conflict-kind classification around the message/type
match so it no longer derives the kind from human-facing Git text; use a
porcelain-stable field or redesign the classification to receive the kind from
the designated progress reader. Preserve the existing downstream refusal
behavior, including its generic fallback when no kind is available.
In `@tests/unit/git-read.test.cjs`:
- Around line 172-194: Update the parseMergeTreeZ tests to use captured
merge-tree -z --name-only fixture bytes directly instead of constructing records
with z(). Preserve coverage for normal conflicts and malformed, stray, reworded,
and prototype-named paths while ensuring the assertions exercise the bundled
Git’s actual byte framing.
In `@tests/unit/patch-apply.integration.test.cjs`:
- Line 1000: Update the rejected-hunk handling near rejected and reject.stderr
so it derives rejected hunk indices from the generated .rej fixture bytes rather
than parsing Git’s human-facing stderr text. Preserve the existing zero-based
index representation and downstream test behavior, without relying on localized
diagnostic wording.
- Line 1010: Update the test around applyPatchToDir to read LONG after the call
and assert that its contents match the unchanged trunk content, rather than
relying only on res.applied.length being zero. Preserve the existing assertion
while adding this observable checkout-state verification.

…ts message (#351) CodeRabbit flagged the parser for reading `CONFLICT (…)` out of Git's human-facing message. The conflicted section of `merge-tree -z` carries the index stages when `--name-only` is not asked for, and the stages are the kind: all three is content, 2 and 3 alone is add/add, a base with one side left is modify/delete. Nothing after the empty field is read any more. The parser test now runs on bytes captured from the bundled Git 2.53.0.

…e is untouched (#351) Two CodeRabbit findings on the acceptance test: `Rejected hunk #N` is diagnostic text, so the rejected hunks are now matched by the headers `--reject` writes into the `.rej` file; and an empty `applied` list does not prove nothing was written, so the file is read back and compared.

## Why `v1.0.1` shipped on 21 August. Trunk carries 45 commits since, and this is the **beta for 1.1.0**, published so contributors can test it before the stable tag. The headline is the bundled Git: the app ships its own Git binary and every checkout operation runs on it, so a contributor no longer needs Git installed (#401 to #411, #418, #420). It also ships the packaging allow-list (#450) and the fixes closed under the v1.1.0 milestone. The version reaches two places a contributor sees, and both must carry the real build: electron-builder embeds it in the artifact names (`wordpress-contributor-toolkit-1.1.0-beta.1-*`), and `src/logging.js` writes `app <version>` as the log's first line, so a problem report names the build it came from. That is why the bump merges before the tag. ## What changes Only the version. All three package-version fields in `package.json` and `package-lock.json` move together from `1.0.1` to `1.1.0-beta.1`. No dependency versions change, and there is no application behaviour change in this PR. ## How to test this Platforms: any for the suite; macOS or Windows for the artifact check that follows the merge. In the repository root: 1. `npm run lint` is clean and `npm test` passes. 2. `node -e "console.log(require('./package.json').version)"` prints `1.1.0-beta.1`. 3. `python3 -c "import json;d=json.load(open('package-lock.json'));print(d['version'], d['packages']['']['version'])"` prints `1.1.0-beta.1 1.1.0-beta.1`. **What must not have happened:** no dependency version may change. `git diff trunk` shows exactly three changed lines, all of them the root package version. After merge, the release build must produce artifacts named `wordpress-contributor-toolkit-1.1.0-beta.1-*`, and the first line of a fresh app log must read `app 1.1.0-beta.1`. ## Risks and limitations No UI change. The risk is a mis-scoped edit in `package-lock.json`, where dependencies also carry `1.0.1`; the replacement was confined to the first 2000 bytes of the file, which holds the two root entries, and both files were re-parsed as JSON afterwards. ## Related Same shape as #244 (v1.0.0-beta.1) and #397 (v1.0.1). --- <details> <summary>Review outcome (required — see AGENTS.md)</summary> Version-only change, three lines. Verified locally on this branch: `npm run lint` clean, `npm test` 1316 pass, 0 fail; `git diff --stat` shows two files, three insertions, three deletions; both JSON files parse. Nothing to fix, nothing deferred. </details> <details> <summary>Screenshots or recording</summary> Nothing on screen changes. </details> 🤖 Generated with [Claude Code](https://claude.com/claude-code) https://claude.ai/code/session_0123opUnXoxs1CAN7YQ7q8KU Co-authored-by: Claude Fable 5.1 <noreply@anthropic.com>

Why
Under #350's contract the conflicts the app shows must be the conflicts Git would show, same files, same regions. #408 moved the ticket move onto
merge-tree --write-tree, but nothing proved its verdicts against a realgit merge, and its one refusal sentence, "Trunk changed the same lines as your work", is false when trunk deleted the file or both sides created it. The acceptance run for #351 (seven three-way fixtures against the bundled Git 2.53.0) found the verdicts match and the sentence does not.What changes
Acceptance tests pin the match.
tests/unit/git-read.integration.test.cjsbuilds seven conflict shapes (same lines, same file far apart, adjacent lines, rename/modify, delete/modify, add/add, three regions with one clash), runs a realgit mergein a throwaway worktree, and assertsmergeTreenames the same files, the same marker regions in the tree it writes, and the same conflict kindsgit mergeprints.tests/unit/patch-apply.integration.test.cjsasserts the regions the app names for a patch are the hunksgit apply --rejectrejects, and records as a characterisation that a neighbouring edit is refused the waygit applyrefuses it, though a merge would take it.The refusal says what kind of conflict it is.
parseMergeTreeZnow reads the conflicted index entriesmerge-tree -zlists (<mode> <oid> <stage>\t<path>, so--name-onlyis gone) and classifies each path by its stages, the waygit statusand every merge tool do: all three stages iscontent, stages 2 and 3 with no base isadd/add, a base with one side left ismodify/delete.mergeTreereturns that askinds,rebaseOntoTrunkattaches it to therebase-conflicterror, main's branches handler forwards it, andrebaseRefusalgroups the paths per kind with one clause each: "Trunk changed the same lines as your work in", "Deleted on one side and changed on the other" (one kind whichever side deleted, so the clause names no side), "Trunk added a file your work also adds, with different content", and a generic "Trunk and your work disagree in" for any other stage combination or when no kind arrived.Deliberately not in this PR: the patch flow stays on two-way
git apply. It agrees withgit applyhunk for hunk, butgit applyrefuses adjacent edits and rename/modify thatgit mergeand GitHub take cleanly. Closing that means a three-way apply, which leaves unmerged index entries in the checkout, and the app first has to recognise that state (#352).How to test this
Platforms: any. The unit and integration layers carry the verdict comparison; the manual steps cover the sentence.
Starting state: a site created by this build, a ticket linked (say #60001) with one edit in
src/wp-login.php, then the ticket unlinked so the work is parked. Then move trunk under it by hand with the bundled Git from the site folder (macOS:<app>/Contents/Resources/app.asar.unpacked/node_modules/dugite/git/bin/git; Windows:resources\app.asar.unpacked\node_modules\dugite\git\cmd\git.exe, add--no-pager).git checkout trunk, deletesrc/wp-login.php,git commit -am "trunk deletes it". Link #60001 again. Expected: the ticket card shows Trunk has moved since this ticket started.Deleted on one side and changed on the other: src/wp-login.php. Nothing was moved.followed by the manual path. Not "changed the same lines".src/wp-login.phpon trunk and commit. Expected after the click:Trunk changed the same lines as your work in: src/wp-login.php. Nothing was moved.src/wp-includes/new.php, park; on trunk addsrc/wp-includes/new.phpwith different content and commit. Expected after the click:Trunk added a file your work also adds, with different content: src/wp-includes/new.php. Nothing was moved.What must not have happened: the ticket's parked work is still byte for byte what it was (
git show ticket/60001:src/wp-login.php), the ticket's recorded base did not move (the notice is still shown after the refusal), andgit statusin the site is clean, no unmerged entries, noMERGE_HEAD.The verdict comparison itself cannot be driven by hand any more precisely than the tests do:
node --test tests/unit/git-read.integration.test.cjsruns the seven shapes against a realgit merge, and breaking the "same files" assertion turns all seven red.Risks and limitations
kindsis derived from index stages, porcelain-stable; nothing in this PR reads Git's human-facing conflict messages (an earlier revision did, and CodeRabbit rightly flagged it). Stage combinations the app has no words for (a rename tangle, a type change) keep no kind and read generically.removeRepo(read-only objects handled, Deleting a site on Windows silently leaves behind anything a real Git wrote #381), because the fixture's own cleanup runs first.Related
Part of #351. Follow-up to #408. The two-way patch gap stays open in #351 and depends on #352 and #290.
Design decisions and alternatives considered
git merge's by construction (same tree). Naming the kind is what a mentor needs to recognise the merge; the line numbers are not.conflictsan array of objects instead of addingkindswas rejected: the paths array is the contract three tests and the renderer already pin, and a separate map degrades cleanly when absent.git apply --3wayfor patches was rejected here (see What changes). The acceptance script that settled this, seven fixtures with rawgit merge,merge-tree,apply --check,apply --rejectandapply --3way, is archived outside the repo.Review outcome (required — see AGENTS.md)
5 [fix here] · 1 [follow-up] — all 5 fixed, the follow-up applied as a JSDoc note.
Fixed: (1) the worktree cleanup in the new integration tests ran after the fixture's own cleanup and silently no-oped, leaking a checkout per test; both tests now remove the worktree with
removeRepo, and the review standard gained a sentence about cleanup that is green while doing nothing. (2) The modify/delete clause named trunk as the deleting side, but Git uses the same kind when the ticket deleted; the clause now names no side, and the matrix gained the mirror shape. (3)KIND_CLAUSES[kind]and the parser'skindsmap read through the prototype; own-property checks and a null-prototype map, with tests forconstructorand__proto__. (4) Two parser branches (a CONFLICT message without a parenthesis, a malformed count) were unreached; both pinned. (5) The no-paths refusal still claimed "changed the same lines"; it now says "disagree", like the layer below.Follow-up, superseded: the first revision read the kind from Git's
CONFLICT (…)message and documented why; CodeRabbit flagged it against §1, and the parser now classifies by index stages instead, with the parser test on bytes captured from the bundled binary. CodeRabbit's other three findings (fixture bytes for the parser test, the.rejfile instead ofRejected hunkstderr, a content assertion after the refused apply) are applied too.Style notes taken: "for instance" in the guide's list of reasons;
strictEqualon a count.Implementation notes
merge-tree -zlists one field per conflicted index entry before an empty field, then informational records (<count>, paths, type, message) that this parser never reads: the type field sayscontentsfor both a content clash and an add/add, so only the stages, or the human message, can tell them apart, and the stages are the porcelain.git mergeleaves no markers for modify/delete (the modified side is left in the tree); the test treats "no markers on either side" as agreement.ticket-rebase.spec.jsis unchanged: its fixture is a content clash, whose sentence did not change.Screenshots or recording
The only visible change is the refusal sentence on the ticket card for delete/modify and add/add conflicts; the manual steps above show the exact text. No recording.
