Summary

  • bpatch apply now runs annotate automatically after a conflict-free apply, so the common apply && annotate flow is one command. --no-annotate opts out; a filtered (-- files) or --changed apply never auto-annotates (they're surgical). continue/skip finish the annotation a paused apply asked for.
  • Fixes the intermittent "apply && annotate doesn't work" cases: annotate now refuses to run mid-conflict-resolution (was committing half-applied trees + reject files into feature history), filters untracked junk (*.rej, *.orig, .browseros-patchignore patterns) the same way extract does, and reports changed files no feature claims as unclaimed instead of silently leaving the checkout dirty.
  • Hardening from three adversarial review rounds: skipped conflicts (including a rename's old path) are excluded from auto-annotate; apply/sync/annotate refuse on unmerged index entries or leftover conflict markers; a parked --no-rebase stash still annotates (pure-patch tree); resolve.Save is atomic; annotate failures are recorded on the result (annotate_error) so the apply outcome is never discarded.

Design

ApplyOptions.AutoAnnotate drives a shared completion step (finishApply for the no-conflict path, finishResolvedRun for continue/skip) that persists the intent through a conflict pause via resolve.State, so the whole flow finishes what apply started. Annotate takes one git status snapshot and partitions it per-feature in memory (no N+1 rescans). The one guard that matters for correctness — don't commit a conflicted/half-merged tree — lives in a single shared requireNoPendingResolution helper (pending resolve state, unmerged entries, or git diff --check conflict markers) that apply, sync, and annotate all call. Default-on annotation is per the explicit request ("apply should automatically do annotate as that is the most common way"); --no-annotate is the escape hatch.

Test plan

  • go test ./..., go vet ./..., make test && make build && make clean in packages/browseros/tools/patch — all green
  • New engine tests: auto-annotate after clean apply, no-op apply still annotates, refuse during resolution / on unmerged files / on conflict markers, skip finishes annotation excluding the half-applied conflict, rename old-path exclusion, parked-clean stash still annotates, missing-registry skip, annotate-error recorded not fatal, unclaimed reporting, junk filtering
  • End-to-end against scripted fake patch-repo + checkout: fresh apply+annotate, idempotent re-run, patch-repo update, genuine conflict → skip → completion, unmerged-guard block+recover

…onflicts and junk

apply now creates feature commits automatically after a conflict-free run
(--no-annotate opts out; filtered applies never auto-annotate). The intent
survives a conflict pause via resolve state, so continue/skip finish the
annotation apply asked for. sync is unchanged.

annotate itself gains three guards that caused 'apply && annotate' to
misbehave:
- refuses to run while a conflict resolution is pending instead of
  committing a half-applied tree (reject files were ending up in feature
  commits)
- filters untracked junk (*.rej, *.orig, .llm/, .browseros-patchignore)
  through the same ignore set extract uses
- reports changed files no feature claims as 'unclaimed' instead of
  silently leaving the checkout dirty
- apply and sync refuse to start while a conflict resolution is pending,
  instead of silently clobbering the paused state and bypassing the
  annotate guard
- continue/skip completion excludes skipped conflicts from annotation:
  the --reject fallback can leave half-applied hunks in tracked files
- --changed applies no longer auto-annotate (surgical, like -- files)
- a repo without a features registry skips annotation instead of
  failing the apply
- annotate failures are recorded on the result (annotate_error) so the
  apply outcome is never discarded; commands render it and exit 1 with
  a standalone-annotate hint
- annotate reuses one status snapshot, rescanning only after a commit
  (untracked-files=all scans are seconds on a Chromium checkout)
- dedupe completion + report-path helpers
- skipped rename conflicts now exclude BOTH the new and old paths from
  auto-annotate, so a half-applied rename's old-file deletion is never
  committed into feature history
- the pending-resolution guard also refuses on unmerged (UU) index
  entries — the state a conflicted stash pop leaves — and auto-annotate
  skips a checkout with a live pending stash, so conflict markers and
  parked local changes never land in feature commits
- resolve.Save writes atomically (temp + rename) so a crash mid-write
  can't leave a corrupt resolve.json that wedges continue/skip/abort
- an annotate failure after a skip now appends the still-uncommitted
  skipped paths to the error, so following the recovery hint does not
  sweep them in
- annotate consumes one status snapshot via in-memory partition instead
  of rescanning after every feature commit
- skipped reasons (no registry, pending stash) surface in output and
  --json (annotate_skipped); Annotate reuses the shared guard helper
…resence

Round-3 review found the pending-stash skip cut both ways: it over-blocked
the safe case (a --no-rebase sync parks changes in the stash, leaving the
worktree pure patches) while the standalone annotate command stayed
unprotected against the unsafe case (a stash rebase leaves conflict markers
as plain modified files, not unmerged index entries).

Replace it with a precise signal: requireNoPendingResolution — shared by
apply, sync, and annotate — now refuses when git's own detector
(git diff --check) reports leftover conflict markers. A parked-clean stash
has no markers and annotates normally; a stash-rebase conflict is blocked on
every path.

Code Review

Tasks

  • Gather context and understand request
  • Read changed files and diff
  • Review engine/apply.go changes
  • Review engine/annotate.go changes
  • Review engine/engine_test.go changes
  • Review cmd/ and resolve/ changes
  • Post final review

This is well-structured, carefully hardened code. Three adversarial review rounds show — the edge cases (rename exclusion, parked stash, marker detection, N+1 status scan, atomic resolve.Save) are all handled. No correctness bugs found. The findings below are mostly observations and minor nits.


Design

The core flow is clean:

  • finishApply / finishResolvedRun are the two completion sites, and both call annotateApplied consistently
  • requireNoPendingResolution is correctly shared by Apply, Sync, and Annotate — one guard, no duplication
  • Persisting AutoAnnotate on resolve.State so continue/skip finish what apply started is the right design

Findings

1. annotateFileSetFrom — set.commit always equals set.report (annotate.go:228-248)

Both set.report and set.commit are populated from changeReportPaths(change):

for _, rel := range changeReportPaths(change) {
    appendUniquePath(&set.report, reportSeen, rel)
}
// ...
for _, rel := range changeReportPaths(change) {   // same source
    appendUniquePath(&set.commit, commitSeen, rel)
}

set.commit is a structural duplicate of set.report. Only set.stage meaningfully differs (uses changeStagePaths). The annotateFileSet type having three fields implies they can diverge, but they never do. This is correct but misleading — a reader expects commit to differ from report. Consider either removing set.commit and using set.report directly in commitFeatureFiles, or documenting why they're always equal.

Fix this →

2. UnmergedFiles — unconventional git diff approach (git.go:592-601)

func UnmergedFiles(ctx context.Context, dir string) ([]string, error) {
    result, err := Run(ctx, dir, nil, "diff", "--name-only", "--diff-filter=U")

git diff --diff-filter=U (index vs worktree) catches unmerged entries, but the canonical approach for merge-conflict detection is git ls-files --unmerged. The current approach works (test validates it), but may produce no output for a file that's unmerged in the index but has no worktree diff (an unusual but theoretically possible state where the user manually updated the file to match one branch). The test covers the common path (stash pop conflict / merge conflict leaving UU status). Low risk; worth noting if UnmergedFiles is ever used outside the conflict guard.

3. resolve.Delete before annotateApplied in finishResolvedRun (apply.go:277-284)

func finishResolvedRun(...) error {
    if err := markApplyComplete(ws.Path, state.BaseCommit, state.RepoRev); err != nil { ... }
    if err := resolve.Delete(ws.Path); err != nil { ... }  // state deleted here
    if state.AutoAnnotate {
        annotateApplied(ctx, ws, repoInfo, skippedExcludePaths(state), result, progress)
    }

If annotateApplied fails, the resolve state is already gone and the Exclude list (skipped paths) lives only in the error message appended to AnnotateError. The error message warns about this correctly. A stricter alternative would keep the resolve state until annotate succeeds, but that would prevent continue/skip/abort from working on a post-resolution annotate failure, so the current tradeoff is reasonable. Worth documenting in the function's godoc that the ordering is intentional: the resolved apply is permanently committed even if annotation fails.

4. ConflictMarkerFiles skips untracked files (git.go:608-635)

git diff --check HEAD only scans tracked files modified vs HEAD. A file created as untracked with conflict markers (e.g., a reject file) wouldn't be caught. This is correct for the targeted scenario (stash-rebase leaves markers in tracked files), and reject files are filtered as junk in annotateChanges anyway. No action needed — just confirming the scope is intentional.

5. git status --untracked-files=all in StatusPorcelain (git.go:135)

--untracked-files=all expands every untracked file individually rather than stopping at directory level. On a Chromium checkout with many untracked files (e.g., build artifacts that escaped .gitignore), this status call could be slow. The single snapshot pattern in annotateChanges (called once, partitioned in memory) is the correct mitigation. Just noting that a noisy checkout could degrade performance here.

6. Auto-annotate enabled for --reset (cmd/apply.go:49)

AutoAnnotate: !noAnnotate && len(filters) == 0 && changed == "",

--reset (which resets all patched files to base before applying) auto-annotates by default. That's consistent with the stated rule ("filtered and --changed applies never auto-annotate; they're surgical"), and --reset is a full apply. This is documented in the LLM guide (llmTxtGuide) but not in the flag usage string. Minor: consider adding a parenthetical to the --reset flag usage or the --no-annotate flag usage to clarify.


Test coverage

Excellent — the new tests cover every case called out in the design doc:

  • TestApplyAutoAnnotatesAfterCleanApply / TestApplyWithNoOpsStillAutoAnnotates — the two happy-path routes
  • TestSkipCompletesAutoAnnotateFromPausedApply — intent survives a conflict pause + skip
  • TestSkippedExcludePathsCoversRenameOldPath — rename old-path exclusion
  • TestAnnotateRefusesDuringConflictResolution / TestApplyRefusesWithUnmergedFiles / TestAnnotateRefusesOnConflictMarkers — all three guards
  • TestApplyAnnotatesWithParkedCleanStash — parked stash doesn't block
  • TestApplyAutoAnnotateSkipsWithoutFeaturesRegistry + TestApplyRecordsAnnotateErrorWithoutFailing — graceful degradation
  • TestAnnotateReportsUnclaimedChanges / TestAnnotateSkipsUntrackedJunk — status correctness

The TestAnnotateRefusesOnConflictMarkers test is particularly important — it validates the precise scenario from the PR description (stash-rebase leaving markers as plain modified files, not unmerged entries) and confirms both Apply and Annotate are blocked.


Summary

No correctness bugs. The three minor actionable items are: (1) simplify annotateFileSet.commit to remove the structural duplication with .report; (2) consider git ls-files --unmerged for UnmergedFiles if robustness across git versions matters; (3) document the intentional resolve.Delete-before-annotate ordering in finishResolvedRun. Everything else is informational. Ready to merge after any desired cleanup.

Greptile Summary

This PR wires bpatch apply into an automatic annotate step after a conflict-free apply, persists that intent through conflict pauses via resolve.State.AutoAnnotate, and hardens all three write commands (apply, sync, annotate) with a shared requireNoPendingResolution guard that refuses to operate on checkouts with a pending resolve state, unmerged index entries, or leftover conflict markers.

  • Auto-annotate flow: finishApply (no-conflict path) and finishResolvedRun (continue/skip path) both call annotateApplied, which records failures on ApplyResult.AnnotateError so apply outcomes are never silently discarded. Filtered (-- files) and --changed applies opt out automatically; --no-annotate is the user-facing escape hatch.
  • Annotate hardening: Single git status snapshot replaces N+1 per-feature scans; junk files (.rej, .orig, patchignore patterns) are filtered the same way extract does; changes no feature claims are reported as Unclaimed and left uncommitted rather than silently dirtying the checkout.
  • Resolve atomicity: resolve.Save now writes to a temp file and renames, so a mid-write crash no longer produces a truncated resolve.json that wedges continue/skip/abort.

Confidence Score: 4/5

Safe to merge; all three write commands now share the same conflict-state guard and the resolve.State is written atomically, closing the previously silent failure modes.

The orchestration logic is well-structured and the test suite is comprehensive, covering the key edge cases (partial apply, skipped renames, junk filtering, unmerged entries, conflict markers, parked stashes). Two small issues keep this below a clean score: annotateApplied appends a skipped-conflict recovery hint to any annotate error when excluded paths are present, which can send a user on the wrong recovery path for unrelated failures; and ConflictMarkerFiles produces an empty error message when git is killed by a signal. Neither causes incorrect data to be committed or state to be lost.

The annotateApplied function in engine/apply.go and ConflictMarkerFiles in git/git.go are the two spots worth a second look before merging.

Important Files Changed

Filename Overview
packages/browseros/tools/patch/internal/engine/apply.go Core orchestration rewrite: adds AutoAnnotate to options/result, refactors no-conflict path into finishApply and conflict-resolution path into finishResolvedRun, adds requireNoPendingResolution guard, and annotateApplied helper. Logic is sound; minor issue with misleading error context appended for unrelated annotate failures when skipped paths are present.
packages/browseros/tools/patch/internal/engine/annotate.go Annotate gains the requireNoPendingResolution guard, switches from per-feature git status scans to a single snapshot with partitioned consumption, adds junk filtering via IgnoreSet, Exclude support for skipped conflict paths, and Unclaimed reporting. The N to 1 status-scan optimization is correct; featureMatchesChange invariant ensures empty-report-set skips never silently drop matched changes.
packages/browseros/tools/patch/internal/git/git.go Adds ConflictMarkerFiles using git diff --check HEAD; parsing and filtering logic are correct for the Chromium path style. The result.Code < 0 branch has a misleading comment and produces an empty error string when git is killed by a signal rather than failing to start.
packages/browseros/tools/patch/internal/resolve/resolve.go Adds AutoAnnotate field to State and makes Save atomic via write-to-temp + rename, correctly cleaning up the temp file on all failure paths. A crash mid-write no longer wedges continue/skip/abort.
packages/browseros/tools/patch/internal/engine/engine_test.go Adds 11 new tests covering auto-annotate, no-op apply annotate, conflict refusal, junk filtering, unclaimed reporting, skip to annotate, rename old-path exclusion, unmerged guard, conflict-marker guard, parked-stash annotate, missing registry, and recorded annotate error. The continue to annotate path through finishResolvedRun lacks a dedicated test.
packages/browseros/tools/patch/cmd/apply.go Adds --no-annotate flag, sets AutoAnnotate only for unfiltered full applies, and wires printAnnotateOutcome / annotateFailureExit into the result path. Logic correctly handles the surgical-apply exclusion.
packages/browseros/tools/patch/cmd/common.go Adds printAnnotateOutcome and annotateFailureExit helpers shared by apply/continue/skip, and updates the help text with annotation rules. Clean and straightforward.
packages/browseros/tools/patch/internal/engine/sync.go Single-line change adds requireNoPendingResolution guard to Sync, consistent with Apply and Annotate hardening.

    The extra context is appended to result.AnnotateError for any error from Annotate when len(exclude) > 0, regardless of whether the failure is related to the excluded paths. If Annotate fails due to an unrelated cause (e.g., git status failing, a corrupted features registry), the user sees something like: "git: exit 128; skipped conflicts remain uncommitted (chrome/old.cc) — resolve or reset them before annotating". This sends them on a wrong recovery path.

**Unreachable branch + empty error on SIGKILL**

After the `if err != nil` guard, `result.Code` is always ≥ 0 for the ordinary non-zero-exit case (`Run` returns `(result, nil)` when `ProcessState != nil`), so `result.Code < 0` is only reachable when git is killed by a signal (SIGKILL/SIGTERM) — the one path where `ProcessState.ExitCode()` returns `-1` with `err = nil`. In that scenario `result.Stderr` is empty, so `errors.New(strings.TrimSpace(result.Stderr))` produces an error whose `.Error()` is `""` — it surfaces to the user as a blank error message from `requireNoPendingResolution`. The comment "A negative code means git never ran" is also inaccurate; the process-never-started case has `ProcessState == nil` and is already caught by `if err != nil`.

### Issue 2 of 3
packages/browseros/tools/patch/internal/engine/apply.go:474-483
**Skipped-conflict hint appended to unrelated annotate errors**

The extra context is appended to `result.AnnotateError` for *any* error from `Annotate` when `len(exclude) > 0`, regardless of whether the failure is related to the excluded paths. If `Annotate` fails due to an unrelated cause (e.g., `git status` failing, a corrupted features registry), the user sees something like: `"git: exit 128; skipped conflicts remain uncommitted (chrome/old.cc) — resolve or reset them before annotating"`. This sends them on a wrong recovery path. The hint is only meaningful when the error is specifically a refusal triggered by the excluded paths themselves; for all other failures the standalone-annotate recovery hint in `printAnnotateOutcome` is already shown.

### Issue 3 of 3

**Missing test for `continue` completing auto-annotate**

`TestSkipCompletesAutoAnnotateFromPausedApply` exercises the apply → conflict pause → skip → finish-with-annotation path and passes through `finishResolvedRun`. The symmetric path via `Continue` is not covered by a dedicated test. Both calls enter `finishResolvedRun` through the same branch (`next >= len(state.Operations) && len(result.Conflicts) == 0`), but a regression specific to how `Continue` loads or forwards `state.AutoAnnotate` would not be caught today — for example, `state.AutoAnnotate` being ignored or not loaded correctly in the `Continue` code path.

P2 Missing test for continue completing auto-annotate

TestSkipCompletesAutoAnnotateFromPausedApply exercises the apply → conflict pause → skip → finish-with-annotation path and passes through finishResolvedRun. The symmetric path via Continue is not covered by a dedicated test. Both calls enter finishResolvedRun through the same branch (next >= len(state.Operations) && len(result.Conflicts) == 0), but a regression specific to how Continue loads or forwards state.AutoAnnotate would not be caught today — for example, state.AutoAnnotate being ignored or not loaded correctly in the Continue code path.

The symmetric path via `Continue` is not covered by a dedicated test. Both calls enter `finishResolvedRun` through the same branch (`next >= len(state.Operations) && len(result.Conflicts) == 0`), but a regression specific to how `Continue` loads or forwards `state.AutoAnnotate` would not be caught today — for example, `state.AutoAnnotate` being ignored or not loaded correctly in the `Continue` code path.

How can I resolve this? If you propose a fix, please make it concise.

Greptile Summary

This PR wires annotate as an automatic post-step of bpatch apply, persisting the intent through conflict pauses via resolve.State.AutoAnnotate so continue/skip finish what apply started. It also hardens the entire annotate/apply/sync surface with a shared requireNoPendingResolution guard (pending resolve state, unmerged index entries, leftover conflict markers), converts the annotate loop to a single git-status snapshot partitioned per-feature (eliminating N+1 rescans), filters untracked junk the same way extract does, and reports unclaimed changes instead of leaving the checkout silently dirty.

  • apply.go / resolve.go: AutoAnnotate flag is saved into the resolve state JSON so conflict pauses survive without losing the annotation intent; finishApply and finishResolvedRun share the completion step; resolve.Save becomes atomic via temp-file rename.
  • annotate.go: single pre-pass snapshot replaces per-feature git status calls; partitionFeatureChanges partitions the snapshot in O(features × changes), correctly consuming entries once; Unclaimed tracks leftover changes no feature owns.
  • git.go: new ConflictMarkerFiles wraps git diff --check HEAD to catch stash-rebase marker residue; the exit-code guard has a gap noted in the review.

Confidence Score: 4/5

The apply-annotate integration, conflict-pause persistence, and single-snapshot annotate loop are all well-constructed. One gap in the new ConflictMarkerFiles function means a fatal git diff --check failure is silently treated as no markers present, which could let an annotate or apply run on a checkout whose conflict state was not actually verified — a one-line fix.

The overall design is solid and the test suite is thorough. The ConflictMarkerFiles exit-code gap is a present defect in a safety guard: git diff --check HEAD exiting 128 returns an empty file list and no error, so requireNoPendingResolution passes without having verified the marker state. All other changed files — the partition loop, atomic resolve.Save, AutoAnnotate persistence, skippedExcludePaths rename handling — reviewed cleanly.

packages/browseros/tools/patch/internal/git/git.go — the ConflictMarkerFiles exit-code guard needs the Code > 2 check added.

Important Files Changed

Filename Overview
packages/browseros/tools/patch/internal/git/git.go Adds ConflictMarkerFiles via git diff --check HEAD; exit-code guard only catches signal-kills (code < 0), silently treating fatal git errors (code 128) as no markers found — the safety guard for annotate/apply can pass even when git couldn't verify the state.
packages/browseros/tools/patch/internal/engine/apply.go Introduces AutoAnnotate intent persisted through conflict pauses, shared finishApply/finishResolvedRun completion paths, requireNoPendingResolution guard, and skippedExcludePaths for rename awareness. Logic is sound; the guard depends on ConflictMarkerFiles which has the exit-code gap noted above.
packages/browseros/tools/patch/internal/engine/annotate.go Refactors to a single pre-pass git status snapshot with partitionFeatureChanges, adds junk filtering, exclude list for skipped conflicts, and Unclaimed reporting. The partition-and-consume loop is correct.
packages/browseros/tools/patch/internal/resolve/resolve.go Adds AutoAnnotate field to State and makes Save atomic via temp-file rename, correctly handling write errors and cleanup.
packages/browseros/tools/patch/internal/engine/engine_test.go Adds 11 new engine tests covering auto-annotate, conflict guards, junk filtering, unclaimed reporting, rename exclusion, parked stash, and annotate error recording.
packages/browseros/tools/patch/internal/engine/sync.go Adds requireNoPendingResolution guard at Sync entry; minimal and correct change.
packages/browseros/tools/patch/cmd/apply.go Adds --no-annotate flag, correctly disables AutoAnnotate for filtered/--changed applies, and routes annotate outcome printing and failure exit through shared helpers.
packages/browseros/tools/patch/cmd/common.go Adds printAnnotateOutcome and annotateFailureExit shared helpers; updates llm-txt guide; clean additions with no issues.
packages/browseros/tools/patch/cmd/continue.go Adds printAnnotateOutcome and annotateFailureExit calls after continue loop, consistent with apply.go.
packages/browseros/tools/patch/cmd/skip.go Mirror of continue.go changes; adds printAnnotateOutcome and annotateFailureExit, consistent and correct.
packages/browseros/tools/patch/cmd/annotate.go Adds Unclaimed section to annotate output with a hint to claim files in features.yaml; clean UI change.

    P1 Silent fatal-error swallow in conflict-marker guard

    Run returns (result, nil) whenever ProcessState != nil regardless of the exit code (see RunEnv lines 63–66). When git diff --check HEAD exits 128 (e.g., "fatal: bad object HEAD" on a corrupted pack, or any other fatal git failure), result.Code = 128, err = nil, and the check result.Code < 0 is false. The function returns (nil, nil) — no markers, no error. requireNoPendingResolution then passes the marker check without having actually verified the checkout state.

    Compare with UnmergedFiles, which returns an error on any Code != 0. A fatal 128 there is surfaced to the caller; here it is silently swallowed. Since requireNoPendingResolution is the last safety gate before Apply/Annotate commits into the tree, a false-clear on the marker check is a meaningful correctness gap. The fix is to also return an error when Code > 2, since legitimate "found issues" from --check only ever produce codes 1–2.

`git diff --check` exits 0 (clean), 1 or 2 (found whitespace/marker issues), or 128 (fatal git error). Only codes 0–2 are "expected signals." Anything above 2 is a fatal error that should be surfaced, not silently treated as "no markers found." This applies the same defensive pattern used by `UnmergedFiles`.

```suggestion
	// --check exits 0 (clean), 1 (found issues), or rarely 2 on some platforms;
	// all are expected signals, not command failures. Negative means the process
	// was signal-killed; anything above 2 is a fatal git error (e.g. exit 128).
	if result.Code < 0 || result.Code > 2 {
		return nil, errors.New(strings.TrimSpace(result.Stderr))
	}
```

…fication rather than a patch (#366)

Five branches had jammed the landing pipeline for four rounds. `land` could say
they conflict and how far the base had travelled; the next question was the one a
person has to answer, and I kept deferring it: rebase, or re-do the work?

Rebasing browseros-ai#1302 would have deleted browseros-ai#1308's landed code and reintroduced a
non-ASCII ellipsis into a redaction the base already performs in ASCII, breaking
L3 in the same stroke. AND A CLEAN REBASE WOULD NOT HAVE SHOWN IT. A semantic
conflict carries no markers: git resolves the text correctly while the combined
code is logically broken - upstream renames a function your commit still calls,
the changes sit on different lines, nothing conflicts, everything is wrong. So
"it applied cleanly" is not evidence, and `salvage.mjs` does not offer it. It
applies nothing. It never rebases. The selftest fails if the words `git rebase`,
`cherry-pick` or `git apply` ever appear in it.

WHAT IT PRODUCES is the standard answer for a branch whose module was
restructured underneath it: use the old diff as a statement of what was WANTED,
not as patches. Concretely - the names the branch introduces that the repository
still does not have:

  queen-1302   8 of 200 candidates absent: quotaAuthority, provider_quota,
               estimated_usd_gate, statusMode, readTelemetry, QuotaAuthority,
               billingProjection, ResearchDeps
  queen-1303   4 of 243: started_running, plantedSecret, startedUnfinished,
               startedRunning
  queen-1387  19 of 273: specQualityHeadingParity, extractorHeadings,
               checkNames, maskNonAscii, RING_COPY, scanMatchingClose, ...

Three branches of 881 added lines reduce to 31 missing names, because most of
what they carried had already landed by another route.

IT IS NOT A PARSE, deliberately. Six false accusations in this project came from
a checker that tried to recognise a declaration by its shape across Swift,
TypeScript and markdown, and the list of ways to spell "define" has no end. Every
identifier-shaped token is a candidate and the BASE TREE decides which are new -
absence is checkable without knowing any language. A hex blob is dropped, because
queen-1303's diff offered `fedcba9876` from a fake sha in a fixture, and
proposing that as a capability the repository lacks is the `node_modules`
accusation in a new costume.

The cap on candidates is printed alongside the total, since a silent truncation
would read as "this is everything".

`--brief` writes the measurement as an issue a bee can pass, and every criterion
is FAIL-TO-PASS BY CONSTRUCTION: the name was measured absent from the base a
moment earlier, so it cannot be satisfied by an empty patch and `verdict-audit`
will check it against both the fork point and the branch without being asked.
Filed as Trinity-S-AI-DNA/trios#1537, browseros-ai#1538 and browseros-ai#1539, all three passing the delegation
gate with their boundaries parsed.

They carry no `queen-authored` label on purpose: that label is `author.mjs`'s own
WIP accounting, and salvage work is not the backlog it is metering.

selftest 155 pass 0 fail. `tri salvage <N> [--brief]`.

…and stop advising a rebase that would destroy work (#369)

For four rounds `why` warned that all remaining accepted branches conflict, that
nothing can land and that the swarm will starve behind them. Mechanically true
and useless: those branches will never land. Their base has moved past them,
replaying one would delete work that landed since, and there was nothing in the
loop that could say so.

`salvage` has now measured what each still owes and filed it as a brief against
today's base - Trinity-S-AI-DNA/trios#1537, browseros-ai#1538, browseros-ai#1539, browseros-ai#1540. So the branches are
recorded as REPLACED, with the issue that replaces each:

  queen-1302 -> browseros-ai#1537   billing mode and quota authority
  queen-1303 -> browseros-ai#1538   the started_running state
  queen-1387 -> browseros-ai#1539   the heading-parity checker
  queen-1422 -> browseros-ai#1540   the noise filter that deleted its answer

Five conflicting branches become one, and the one that remains - queen-1484 - is
not debt either: it is an OPEN issue whose own criterion fails against the base
today, which the swarm can pick up as ordinary work.

RECORDED, NEVER INFERRED. Nothing here guesses that a branch is superseded.
Someone says so and says by what, in a file, with a timestamp. The branches
themselves are untouched: no deletion, no force, nothing irreversible. The
selftest fails if `--force`, `branch -D` or `push --delete` ever appear in this
file.

AND THE ADVICE CHANGED, because it was wrong. For four rounds this tool told a
reader that a conflicting branch "needs a rebase, or an honest closure as
superseded". Rebasing browseros-ai#1302 would have deleted browseros-ai#1308's landed code and
reintroduced a non-ASCII ellipsis into a redaction the base already performs in
ASCII. It now says what was learned:

  A rebase is usually the WRONG remedy once the base has moved: replaying an old
  branch can delete work that landed since, and applying cleanly proves nothing,
  because a semantic conflict carries no markers.
    tri salvage <N>   measures what the branch would still add, asks the issue
                      its own criterion against the base, and writes the
                      remainder as a brief

A tool that recommends the destructive option in one line, every round, for four
rounds, is worse than one that says nothing.

selftest 160 pass 0 fail.

…s-ai#1539) (#370)

queen-1387 carried accepted work that never reached the base: a
heading-parity gate exercised by a bun test. The base has since landed the
Swift-side half in its own form (7e8275d: the success-criteria Check reads
the bare identifier criteriaHeadings, so extractor and judge share one list)
plus a CLI gate, trios/tools/spec-heading-parity.mjs, that nothing invokes.
What never arrived is the property held as a module a test can import, so
the parity claim runs with the suite instead of when someone remembers a
command.

trios/tools/spec-quality-heading-parity.mjs is that module, written against
QueenSpecQuality.swift as it stands. specQualityHeadingParity(swiftPath)
reads both lists out of the source at run time - extractorHeadings from
'static let criteriaHeadings', checkNames from every hasSection(body, ...)
argument in the success-criteria Check's met: span - and reports any
extractor heading no check name can see, with the same anchored-substring
test and in the same direction as the Swift. It doubles as a CLI over both
compiled copies, masking non-ASCII in its output: exit 0 parity, 1 orphan,
2 unparsable.

queen-spec-heading-parity.test.ts pins both compiled copies (the ring copy
and the queen-core copy) green - extractor=10, orphans=0, lists identical
across copies - and carries a negative control: a heading spliced into the
extractor list that no check name can see must be named as the one orphan,
because a gate that cannot fail was never a gate. The suite was seen
failing before passing: with orphan reporting mutated out, exactly that
control fails.

The two Swift copies are deliberately untouched. The fix they carried is
already the base's current state, and replaying the old branch's hunk would
regress it: its separate Acceptance arm has been subsumed by
criteriaHeadings since 7e8275d. Editing them would also put their
Cyrillic criteriaHeadings under the ASCII-only rule this task demands of
changed files.

--no-verify because the pre-commit hook cannot run in this container: its
biome-check shells out to npx, which is absent (the equivalent check,
bunx biome check on the staged test file, exits 0 with nothing to write),
and its file-length step uses bash [[ under sh and excludes tests/** in
any case. The commit-msg conventional check was run by hand: OK.

…pped connection, and I had seen it before (#373)

THE SALVAGE LOOP CLOSED, and looking at it found the defect.

Last round `salvage` measured what four stale branches still owed and wrote each
as a brief. This round the swarm executed three of them. The audit:

  browseros-ai#1537  8 promised identifiers absent at the fork point, present on the branch, 6 in a declaration
  browseros-ai#1538  4 of 4, 3 in a declaration
  browseros-ai#1539  10 of 10, 9 in a declaration
  browseros-ai#1484  its own criterion failed at the fork point and passes on the branch

Four for four, every one proven fail-to-pass. Measurement -> brief -> work ->
audit -> land works end to end, and #370, #371 and #372 carry it into the base.

BUT THEY HAD BEEN FINISHED FOR A ROUND AND NOBODY COULD SEE THEM. The Queen's own
board said "completed" for browseros-ai#1538, browseros-ai#1539 and browseros-ai#1484 - dispatched, run for 9 to 15
minutes, 23 to 35 thousand output tokens each, reviewed and ACCEPTED - while no
branch existed on the remote and no comment existed on the issue.

`push-work` is the only way a bee's work leaves the container. It had died on
`Operation timed out (os error 60)` from `railway ssh`, which is a network hop
failing the way network hops fail. A retry thirty seconds later pushed thirteen
branches.

AND I HAD SEEN IT BEFORE. Two rounds ago the chain printed `push-work=FAILED`, I
re-ran it by hand, it worked, and I wrote it off as transient without changing
anything. "It worked when I tried again" is not a diagnosis. It is the
observation that a retry belongs in the code, and skipping that step cost a round
of invisible work.

So the channel retries with backoff, and only for channel-shaped failures -
"Operation timed out", "Connection reset", "SendRequest", ETIMEDOUT, 502. A git
answer is an answer: `! [rejected] ... (non-fast-forward)` is not retried,
because a partly-rejected push is a normal outcome the reporting already knows
how to describe. The selftest pins both directions.

AND A CHANNEL FAILURE MUST NOT LOOK LIKE "NOTHING TO PUSH". Both end without
pushing anything and only one of them is fine. The chain reads this step's words,
so the words differ:

  COULD NOT REACH THE CONTAINER after retrying.
    could not reach the container after 3 attempts: ...
    Nothing was pushed and nothing was inspected. This is NOT "nothing to push":
    this step is the only way a bee's work leaves the container, and it did not run.

Exit 3, and never a stack trace.

selftest 162 pass 0 fail.

…ad been failing two thirds of the time (#374)

I came to watch four salvage briefs through the swarm. They passed - and looking
at them found something much larger.

THE SALVAGE LOOP CLOSED. browseros-ai#1537, browseros-ai#1538 and browseros-ai#1539 were executed by bees and every
promised identifier is absent at the fork point and present on the branch: 8 of
8, 4 of 4, 10 of 10, six to nine of them in a declaration. browseros-ai#1484's own criterion
failed at the fork point and passes on the branch. Landed as #370, #371, #372.
Measurement -> brief -> work -> audit -> land, proven end to end.

BUT THEY HAD BEEN FINISHED FOR A ROUND AND INVISIBLE. The Queen's board said
"completed" for three of them - dispatched, run 9 to 15 minutes, 23 to 35
thousand output tokens each, reviewed and ACCEPTED - with no branch on the remote
and no comment on the issue. `push-work` had died on `Operation timed out (os
error 60)`. A retry pushed thirteen branches.

I HAD SEEN IT BEFORE AND FIXED NOTHING. Two rounds ago the chain printed
`push-work=FAILED`, I re-ran it by hand, it worked, and I called it transient.
"It worked when I tried again" is not a diagnosis; it is the observation that a
retry belongs in the code.

SO I ASKED THE LEDGER, for the first time in the whole run. Over 23 hours:

  reap        45 of 63 runs failed   71%
  lease       43 of 63               68%
  push-work   46 of 70               66%
  close-done  32 of 70               46%

Those are exactly the four steps that FREE the swarm. All four reach the
container through `railway ssh` and each carried its own six-line copy of the
call. None of them retried. They had been failing about two thirds of the time
for as long as the ledger goes back, and it was invisible because every run only
ever reported itself - a single failure looks like bad luck, and only the record
shows it is the system.

`channel.mjs` is that call, once. It retries a CHANNEL failure - "Operation timed
out", "Connection reset", "SendRequest", ETIMEDOUT, 502 - and never retries an
ANSWER: `git push` exits non-zero when a ref is rejected, and a partly-rejected
push is a normal outcome its caller already describes. Retrying an answer would
be as wrong as crashing on a dropped connection, and the selftest pins both
directions. Copying the push-work fix into three more files would have been L2
again: a rule transcribed four times is four rules that agree until someone edits
one.

It also marks the failure, so a caller can tell "I looked and found nothing" from
"I never looked" - the same silence, completely different facts.

AND THE LEDGER RECORDED NO REASON FOR ANY OF THEM. `line` is set only when a
SUMMARY pattern matches, and no pattern matches a failure, so every one of the 46
FAILED entries carries an empty summary. The console had the reason. The record
did not, and those failures can never now be diagnosed. Both chains keep the last
six lines of a failing step from here on.

`tri failures` reads the ledger backwards; `tri channel` says whether the one way
in is up. Four `tri` commands were also passing their own name through as an
argument, which is why `tri failures --since 1` looked for a step called
"failures".

selftest 166 pass 0 fail.
