feat: add commit attribution with per-file AI contribution tracking (#3115)
* feat: add commit attribution with per-file AI contribution tracking via git notes

Track character-level AI vs human contributions per file and store
detailed attribution metadata as git notes (refs/notes/ai-attribution)
after each successful git commit. This enables open-source AI disclosure
and enterprise compliance audits without polluting commit messages.

* feat: enhance commit attribution with real AI/human ratios and generated file exclusion

- Replace line-based diff with a prefix/suffix character-level algorithm
  for precise contribution calculation (e.g. "Esc"→"esc" = 1 char, not whole line)
- Compute real AI vs human contribution percentages at commit time by analyzing
  git diff --stat output: humanChars = max(0, diffSize - trackedAiChars)
- Add generated file exclusion (lock files, dist/, .min.js, .d.ts, etc.)
  ported from an existing generatedFiles.ts
- Add file deletion tracking via recordDeletion()
- Update git notes payload format: {aiChars, humanChars, percent} per file
  with real percentages instead of hardcoded 100%

* feat: add surface tracking, prompt counting, session persistence, and PR attribution

Align with the full attribution feature set:
- Surface tracking: read QWEN_CODE_ENTRYPOINT env var (cli/ide/api/sdk),
  include surfaceBreakdown in git notes payload
- Prompt counting: incrementPromptCount() hooked into client.ts message
  loop, tracks promptCount/permissionPromptCount/escapeCount
- Session persistence: toSnapshot()/restoreFromSnapshot() for serializing
  attribution state; ChatRecordingService.recordAttributionSnapshot()
  writes to session JSONL; client.ts restores on session resume
- PR attribution: addAttributionToPR() in shell.ts detects `gh pr create`
  and appends "🤖 Generated with Qwen Code (N-shotted by Qwen-Coder)"
- Session baseline: saves content hash on first AI edit of each file
  for precise human/AI contribution detection
- generatePRAttribution() method for programmatic access

* fix: audit fixes — initial commit handling, cron prompt exclusion, failed commit counter preservation

- Handle initial commit (no HEAD~1) by detecting parent with rev-parse
  and falling back to --root for first commit in repo
- Exclude Cron-triggered messages from promptCount (not user-initiated)
- Add commitSucceeded parameter to clearAttributions() so failed/disabled
  commits don't reset the prompts-since-last-commit counter
- Add test for clearAttributions(false) behavior

* fix: cross-platform and correctness fixes from multi-round audit

- Normalize path.relative() to forward slashes for Windows compatibility
- Use diff-tree --root for initial commits (git diff --root is invalid)
- Replace String.replace() with indexOf+slice to avoid $& special patterns
- Fix clearAttributions(false→true) when co-author disabled but commit succeeded
- Use real newlines instead of literal \n in PR attribution text
- Add surface fallback in restoreFromSnapshot for version compatibility
- Fix single-quote regex to not assume bash supports \' escaping
- Case-insensitive directory matching in generated file detection
- Handle renamed file brace notation in parseDiffStat

* fix(attribution): also snapshot on ToolResult turns so resume keeps tool edits

Previously, recordAttributionSnapshot() only ran at the start of UserQuery
and Cron turns — before the tools for that turn had executed. A session
that wrote a file in turn 1 and committed in turn 2 (across process
boundaries via --resume) lost the tracked edit: the last persisted
snapshot was the turn-1-start snapshot (empty fileStates), so on resume
the attribution service restored empty state and no git notes were
attached to the commit.

Move the snapshot call out of the UserQuery/Cron conditional and run it
on every non-Retry turn. ToolResult turns are scheduled right after
tools execute, so their start-of-turn snapshot now captures any edits
those tools made. Retry turns are skipped since the state is unchanged
from the prior turn.

Added unit tests asserting the snapshot fires for ToolResult/UserQuery
turns and skips Retry turns.

Verified end-to-end in a scratch repo: write-file in turn 1 (no commit)
→ exit → --resume → commit in turn 2 → git notes now contain the
recorded file with correct aiChars and promptCount: 2.

* refactor(attribution): merge duplicate retry guard and update stale doc

Collapse the two back-to-back messageType !== Retry blocks in
sendMessageStream into one, and refresh chatRecordingService's
recordAttributionSnapshot doc comment to reflect that snapshots fire
on every non-retry turn (not just after user prompts).

* feat(attribution): split gitCoAuthor into independent commit and pr toggles

Matches the shape used upstream in Claude Code's `attribution.{commit,pr}`
so users can disable the PR body line without losing the commit-message
Co-authored-by trailer (or vice versa). The previous boolean forced both
to move together, which conflated two different surfaces.

- settingsSchema: gitCoAuthor becomes an object with nested commit/pr
  booleans, each `showInDialog: true` so both appear in /settings.
- Config constructor accepts legacy boolean (coerced to { commit: v, pr: v })
  so stored preferences from the pre-split schema carry over.
- shell.ts: attachCommitAttribution and addCoAuthorToGitCommit read .commit;
  addAttributionToPR reads .pr.

* feat(settings): add v3→v4 migration for gitCoAuthor shape change

Legacy gitCoAuthor was a single boolean and shipped ~4 months ago; the
previous commit split it into { commit, pr } sub-toggles. Without a
migration, users who had set gitCoAuthor: false would see the settings
dialog show the default (true) for both sub-toggles — misleading and
likely to flip their preference on the next save because getNestedValue
returns undefined when asked for .commit on a boolean.

- New v3-to-v4 migration expands boolean → { commit: v, pr: v },
  preserves already-object values, resets invalid values to {} with a
  warning.
- SETTINGS_VERSION bumped 3 → 4; existing integration assertions use the
  constant so the next bump is a single-line change.
- Regenerate vscode-ide-companion settings.schema.json to reflect the
  new nested shape.
- Docs: split the single gitCoAuthor row into .commit and .pr.

* test(migration): cover null/array/number and partial object for v3-to-v4

The migration already treats any non-boolean, non-object value as invalid
(reset to {} with warning), but the existing test only exercised the
string "yes" branch. Add parameterized cases for null, array, and number
so a future regression that accepts these in the valid bucket gets caught.
Also cover partial objects — the migration must not paternalistically
fill defaults; that responsibility lives in normalizeGitCoAuthor at the
Config boundary.

* fix(shell): address PR review for compound commits and PR body escaping

Two critical issues called out in review:

1. attachCommitAttribution treated the final shell exit code as proof
   that `git commit` itself failed. For compound commands like
   `git commit -m "x" && npm test`, the commit can succeed and a later
   step can fail; the previous code then cleared attribution without
   writing the git note. Now we snapshot HEAD before the command (via
   `git rev-parse HEAD` through child_process.execFile, kept independent
   of the mockable ShellExecutionService) and detect commit creation by
   HEAD movement, so attribution lands whenever a new commit was created
   regardless of later steps.

2. addAttributionToPR spliced the configured generator name into the
   user-approved `gh pr create --body "..."` argument verbatim. A name
   containing `"`, `$`, a backtick, or `'` could break the command or be
   evaluated as command substitution. Now we shell-escape the appended
   text per the surrounding quote style before splicing.

Tests cover the new escape paths for both double- and single-quoted
bodies, including a generator name designed to break interpolation
(`$(rm -rf /) "danger" \`eval\``) and one with an apostrophe.

* fix(attribution): address Copilot review on shell, schema, and totals

Six items called out on PR #3115 by Copilot:

- shell.ts: addAttributionToPR's bash quote escaping doesn't apply to
  cmd.exe / PowerShell, where `\$` and `'\''` aren't honored. Skip the
  PR body rewrite entirely on Windows — losing PR attribution there is
  preferable to corrupting the user-approved `gh pr create` command.

- attributionTrailer.ts + shell.ts call site: buildGitNotesCommand used
  bash-style single-quote escaping on the JSON note, which is broken on
  Windows. Switched to argv form (`{ command, args }`) and routed the
  invocation through child_process.execFile so shell quoting is bypassed
  entirely. Tests updated to assert the argv shape.

- commitAttribution.ts: when a tracked file's aiChars exceeded the diff
  --stat-derived diffSize (long-line edits where diffSize ≈ lines * 40),
  humanChars clamped to 0 but aiChars stayed inflated, leaving aiChars +
  humanChars > the committed change magnitude. Clamp aiChars to diffSize
  so the totals stay consistent.

- shell.ts parseDiffStat: only normalized rename brace notation
  (`{old => new}`). Cross-directory renames emit `old/path => new/path`
  without braces, leaving diffSizes keyed by the full string. Added a
  second normalization step.

- shell.ts: addAttributionToPR docstring claimed `(X% N-shotted)` but
  the implementation only emits `(N-shotted by Generator)`. Updated the
  docstring to match the actual behavior.

- settingsSchema.ts + generator: gitCoAuthor went from boolean to object
  in the V4 migration. The exported JSON Schema now wraps the field in
  `anyOf: [boolean, object]` (via a new `legacyTypes` hint on
  SettingDefinition) so users with a stored boolean don't see a spurious
  IDE warning before their next launch runs the migration.

* fix(attribution): parse binary diffs, source generator from model, sync schema $version

Three follow-up review items from Copilot:

- parseDiffStat now handles git's binary-diff format (`path | Bin A ->
  B bytes`) using the byte delta with a floor of 1. Without this,
  binary edits arrived at the attribution payload as diffSize=0 and
  were silently dropped. Also extracted the parser to a top-level
  exported function so the binary path is unit-testable; added five
  targeted cases (text/binary/rename normalisation/summary skip).

- attachCommitAttribution now passes `this.config.getModel()` into
  generateNotePayload instead of the user-configurable
  `gitCoAuthor.name`. The note's `generator` field reflects which
  model produced the changes — and CommitAttributionService's
  sanitizeModelName() actually has the codename to scrub now.

- generate-settings-schema.ts imports SETTINGS_VERSION instead of
  hardcoding `default: 3`, so a future bump propagates to the emitted
  JSON schema in one place. Regenerated settings.schema.json bumps
  $version's default from 3 to 4 to match the V4 migration.

* fix(attribution): repo-root baseDir, escape co-author trailer, switch to numstat

Three Critical items called out by wenshao:

- attachCommitAttribution was passing config.getTargetDir() as `baseDir`
  to generateNotePayload, but getCommittedFileInfo returns paths
  relative to `git rev-parse --show-toplevel`. When the working
  directory was a subdirectory of the repo, path.relative produced
  `../...` keys that never matched in the AI-attribution lookup,
  silently zeroing out attribution for every file outside getTargetDir.
  StagedFileInfo now carries an optional `repoRoot` (filled in by
  getCommittedFileInfo via `git rev-parse --show-toplevel`) and the
  caller prefers it over the target dir.

- addCoAuthorToGitCommit interpolated `gitCoAuthorSettings.name` and
  `.email` into the rewritten command without escaping. A name
  containing `$()`, backticks, or `"` could be evaluated as command
  substitution under double quotes, or break the user-approved
  `git commit -m "..."` quoting. Now escapes per the surrounding quote
  style with the same helpers addAttributionToPR uses, gates on
  non-Windows for the same shell-quoting reason, and fixes the regex
  to accept `-m"msg"` shorthand (no space) so users who type the
  bash-shorthand form aren't silently denied a trailer.

- parseDiffStat used `git diff --stat` output and approximated each
  line as ~40 chars by parsing a graphical text bar. Replaced with
  `git diff --numstat` which gives unambiguous integer
  additions+deletions per file; the heuristic remains but the parser
  is no longer fooled by the visual `++--` markers. Binary entries
  fall back to a fixed estimate so they still land in the map (rather
  than dropping out as diffSize=0).

Suggestions also addressed: stale duplicate JSDoc on
addCoAuthorToGitCommit removed, misleading `clearAttributions`
comments rewritten to describe what the boolean argument actually
does. Tests cover the new shorthand path, escape behavior, and
numstat parsing (text/binary/rename/malformed).

* fix(shell): shell-aware git-commit detection and apostrophe-escape handling

Two more Critical items called out by wenshao plus the matching Copilot
quote-handling notes:

- attachCommitAttribution and addCoAuthorToGitCommit now go through a
  shell-aware `looksLikeGitCommit` helper instead of a raw
  `\bgit\s+commit\b` regex. The helper splits the command on shell
  separators (`splitCommands`) and checks each segment, so `echo "git
  commit"` no longer triggers attribution clearing or trailer
  injection. The same helper bails on any segment that contains `cd`
  or `git -C <path>`, since either could redirect the commit into a
  different repo than our cwd — writing notes or capturing HEAD there
  would corrupt unrelated state.

- The post-command attribution call now runs regardless of whether the
  shell wrapper aborted. `git commit -m "x" && sleep 999` could move
  HEAD and then time out, leaving the new commit without its
  attribution note while the stale per-file attribution stayed around
  for a later unrelated commit. attachCommitAttribution still gates on
  HEAD movement, so it's a no-op when no commit was actually created.

- The `-m '...'` and `--body '...'` regexes used to match only the
  first quote segment, so a command like `git commit -m 'don'\''t'`
  (bash's standard apostrophe-escape form) would have the trailer
  spliced mid-message and break the command's quoting. The single-
  quote patterns now use a negative lookahead / inner alternation to
  either skip those messages entirely (commit path) or match the
  whole escape-aware body (PR path).

Tests cover the new behavior: quoted "git commit" is left alone, the
`cd && git commit` and `git -C` patterns get no trailer, and the
apostrophe-escape form passes through unchanged for both `-m` and
`--body`.

* fix(attribution): drop magic 100 fallback for empty deletions

Deleted files with no AI tracking now use diffSize directly. With
numstat as the input source, diffSize is an exact count, and an
empty-file deletion legitimately reports zero — a magic fallback would
only inflate totals.

* fix(shell): broaden git-commit detection, gate background, drop dead helpers

Five Copilot follow-ups:

- looksLikeGitCommit now strips leading env-var assignments
  (`GIT_COMMITTER_DATE=now git commit ...`) and a small allowlist of
  safe wrappers (`sudo`, `command`) before matching. The previous
  exact-prefix match silently skipped trailer injection on common
  real-world commit forms.

- A new looksLikeGhPrCreate (same shell-aware shape) replaces the raw
  `\bgh\s+pr\s+create\b` regex in addAttributionToPR, so quoted text
  like `echo "gh pr create --body \"x\""` no longer triggers a
  command-string rewrite.

- executeBackground refuses to run `git commit` and tells the user to
  re-run foreground. The BackgroundShellRegistry lifecycle has no
  hook for the post-command pre/post-HEAD comparison or git-notes
  write, so allowing the commit through would create the new commit
  without notes and leak stale per-file attribution into the next
  foreground commit.

- recordDeletion was unused outside its own test — removed (and the
  test). When AI-driven deletions need tracking we'll add it with an
  actual integration point rather than carrying dead API surface.

- generatePRAttribution was likewise unused; addAttributionToPR
  builds the trailer string inline. The two formats had already
  diverged. Removed the helper and its tests; reviving from git
  history is straightforward if a future caller needs it.

Tests: env-var and sudo prefixes now produce trailers; quoted
"gh pr create" leaves the command unchanged; existing 81 shell tests
still pass alongside the trimmed 25 commitAttribution tests.

* fix(shell): unified git-commit detection split by intent

Six items called out across CodeQL, Copilot, and wenshao:

- The earlier `looksLikeGitCommit`/`stripCommandPrefix` returned a
  single yes/no and rejected ANY `cd` in the chain. That fixed the
  wrong-repo case but also disabled attribution for `git commit -m
  "x" && cd ..` (commit already landed safely in our cwd; the cd
  came after). It also conflated three distinct decisions onto one
  predicate.

  New `gitCommitContext` returns both `hasCommit` and
  `attributableInCwd`, walking segments in order so that a `cd`
  AFTER the commit doesn't invalidate it. Callers now pick the right
  arm:
  - background-mode refusal uses `hasCommit` (refuses even
    `cd /elsewhere && git commit` since we can't attribute it
    afterward either way)
  - HEAD snapshot, addCoAuthorToGitCommit, and the
    attachCommitAttribution gate use `attributableInCwd`

- Tokenisation switches from a regex while-loop to `shell-quote`'s
  `parse`. Quoted env values like `FOO="a b" git commit` now skip
  correctly (the old `\S*\s+` form would cut after the opening
  quote). Eliminates the CodeQL polynomial-regex alert at the same
  time since the `\S*\s+` pattern is gone.

- attachCommitAttribution now snapshots prompt counters via
  `clearAttributions(true)` whenever a commit lands, even if no
  per-file attributions were tracked. Previously the early-return
  on `hasAttributions() === false` meant `promptCountAtLastCommit`
  never advanced, so a later `gh pr create` reported an inflated
  N-shotted count spanning multiple commits.

Tests: env-var and sudo prefixes still produce trailers; quoted
"git commit" / "gh pr create" leave commands unchanged; cd BEFORE
commit suppresses the rewrite while cd AFTER commit does not; `git
-C <path> commit` is treated as a commit (refused in background)
but not as attributable.

* fix(shell): position-independent git subcommand detection + bash-shell guard

Six review items, two of them critical:

- gitCommitContext was checking fixed-position tokens (`arg1`, `arg3`)
  and missed every git invocation that puts a global flag between
  `git` and the subcommand: `git -c user.email=x@y commit`,
  `git --no-pager commit`, `git -C /p -c k=v commit`, etc. In
  background mode these would slip past the refusal guard; in
  foreground they got no co-author trailer, no git note, and no
  prompt-counter snapshot. New `parseGitInvocation` walks past
  git's global flags (with their values) before reading the
  subcommand, and reports `changesCwd` for `-C` / `--git-dir` /
  `--work-tree`.

- The Windows guard on addCoAuthorToGitCommit and addAttributionToPR
  used `os.platform() === 'win32'`, which incorrectly skipped Windows
  + Git Bash (`getShellConfiguration().shell === 'bash'`). Switched
  both to gate on `getShellConfiguration().shell !== 'bash'` so Git
  Bash users keep the feature.

- attachCommitAttribution was re-parsing `gitCommitContext(command)`
  even though `execute()` already gates on `commitCtx.attributableInCwd`.
  Removed the redundant re-parse — drift between the two checks would
  silently diverge trailer injection from git-notes writes.

- tokeniseSegment (formerly tokeniseProgram) now logs via debugLogger
  on parse failure instead of swallowing silently. Easier to debug
  if shell-quote ever throws on something unusual.

- Added a comment on `cwdShifted` documenting that it's a one-way
  latch — `cd src && cd ..` will still skip attribution. The
  trade-off matches the wrong-repo guard's "better miss than corrupt
  unrelated repos" intent.

- Stale `--stat` reference in the aiChars-clamp comment updated to
  `--numstat` to match the actual git command in
  ShellToolInvocation.getCommittedFileInfo.

Tests: `git -c key=val commit` and `git --no-pager commit` now
produce a trailer; existing 82 shell tests still pass.

* fix(shell): refuse multi-commit attribution; misc review follow-ups

Five follow-ups from the latest review pass:

- attachCommitAttribution now refuses to write a single git note for
  shell commands that produce more than one commit (e.g.
  `git commit -m a && git commit -m b`). The singleton's per-file
  attribution map can't be partitioned across the individual commits,
  so attaching the combined note to HEAD would mis-attribute earlier
  commits' changes to the last one. Walks `preHead..HEAD` via
  `git rev-list --count`; on multi-commit detection it snapshots the
  prompt counters and bails with a debug warning instead of writing
  a misleading note.

- parseGitInvocation now recognises the attached `-C/path` form
  (e.g. `git -C/path commit -m x`). shell-quote tokenises that as a
  single `-C/path` token which previously fell to the generic flag
  branch with `changesCwd = false`, leaving an out-of-cwd commit
  classified as attributable.

- attachCommitAttribution dropped its unused `command` parameter
  (the caller already gates on `commitCtx.attributableInCwd`, so
  re-parsing was removed earlier; the parameter became dead).

- Added wiring guards in edit.test.ts and write-file.test.ts:
  AI-originated edits/writes hit `CommitAttributionService.recordEdit`,
  `modified_by_user: true` skips, and write-file's distinction
  between a true new file and an overwritten empty file (`null` vs
  `''` old content) is now pinned by `aiCreated` assertions.

* fix(attribution): partial-commit clear, symlink baseDir, gh/git flag handling

Two Critical items, two Copilot, and five wenshao Suggestions:

- attachCommitAttribution's `finally` block used to call
  `clearAttributions()` unconditionally, wiping per-file tracking
  for files the AI had edited but the user excluded from this
  commit. Added `clearAttributedFiles(committedAbsolutePaths)` to
  the service and the call site now passes only the paths that
  actually landed in this commit; entries for un-`add`ed files stay
  pending for a later commit.

- generateNotePayload now runs both `baseDir` and each tracked
  absolute path through `fs.realpathSync` before `path.relative`.
  On macOS in particular `/var` symlinks to `/private/var`, so the
  toplevel from `git rev-parse --show-toplevel` and the absolute
  path captured by edit/write-file tools could diverge — producing
  `../../actual/path` keys in the lookup that never matched and
  silently zeroed all per-file AI attribution.

- tokeniseSegment now consumes value-taking sudo flags (`-u`,
  `-g`, `-h`, `-D`, `-r`, `-t`, `-C`, plus the long forms). Without
  this, `sudo -u other git commit` left `other` standing in for
  the program name and skipped the trailer entirely.

- A duplicate JSDoc block above `countCommitsAfter` (a leftover
  from the earlier extraction of `getGitHead`) was removed; both
  helpers now have one accurate comment each.

- attachCommitAttribution's multi-commit guard now also runs when
  `preHead === null` (brand-new repo), via `git rev-list --count
  HEAD`. A compound `git init && git commit -m a && git commit -m b`
  no longer slips through and mis-attributes combined data to the
  last commit.

- addCoAuthorToGitCommit's `-m` matching switched to `matchAll` and
  takes the LAST match. `git commit -m "title" -m "body"` puts the
  trailer at the end of the body so `git interpret-trailers`
  recognises it; the previous first-match behaviour stuffed the
  trailer in the title where git treats it as plain message text.

- addAttributionToPR's `--body` regex accepts both space and
  `=` separators (`--body "..."` and `--body="..."`); the `=` form
  is common with gh.

- New `parseGhInvocation` walks past gh's global flags
  (`--repo`, `-R`, `--hostname`) so `gh --repo owner/repo pr
  create ...` is detected. The earlier fixed-position check at
  tokens[1]/tokens[2] missed any command with a global flag.

- getCommittedFileInfo now fans out the two `rev-parse` calls and
  the three diff calls with `Promise.all`. They're independent and
  serialising them was paying spawn latency 5× per commit.

Tests: sudo with `-u user`, multi `-m`, `gh --repo owner/repo`,
`--body="..."`, plus the existing 84 shell tests still pass.

* fix(attribution): canonicalize file paths centrally in CommitAttributionService

Two related Copilot follow-ups:

- recordEdit/getFileAttribution/clearAttributedFiles now run input
  paths through fs.realpathSync before storing/looking up, so a
  symlinked path (e.g. macOS /var ↔ /private/var) resolves to the
  same key regardless of which form the caller passes. Previously
  edit.ts/write-file.ts handed in non-realpath'd absolute paths
  while generateNotePayload tried to realpath only inside its
  lookup loop, leaving partial-clear and clear-on-finally paths
  unable to find entries when the forms diverged.

- restoreFromSnapshot also canonicalises on the way in so a
  session resumed from a pre-fix snapshot (where keys may not
  have been canonical) ends up with the same shape as newly
  recorded entries — otherwise a single file could end up with
  two parallel records.

- generateNotePayload's lookup loop dropped its per-entry realpath
  call (now redundant since keys are canonical at write time),
  keeping only the realpath of `baseDir` (which still comes from
  `git rev-parse --show-toplevel` and may be a symlink).

- Updated `clearAttributedFiles` doc to describe the new semantics:
  callers can pass either the resolved repo-relative path or an
  already-canonical absolute path, and either will match.

* fix(attribution): canonicalize-from-root cleanup; fix mixed-quote -m / gh -R=

Five review items, one Critical:

- attachCommitAttribution now canonicalises via the repo *root* (one
  realpath call) and resolves committed paths against that canonical
  root, rather than per-leaf realpath inside clearAttributedFiles.
  At cleanup time the leaf for a just-deleted file no longer exists,
  so per-leaf fs.realpathSync would fail and silently fall back to a
  non-canonical path that misses the stored canonical key — leaving
  stale attributions for deleted files.
  clearAttributedFiles drops its internal realpath and now documents
  the canonical-paths-required precondition explicitly.

- addCoAuthorToGitCommit picks the LAST `-m` regardless of quote
  style. Previously `doubleMatch ?? singleMatch` always preferred
  the last double-quoted match, so `git commit -m "Title" -m
  'Body'` injected the trailer into the title where git
  interpret-trailers would silently ignore it. Now compares match
  indices, and the escape helper follows the actually-selected
  match's quote style.

- parseGhInvocation handles `-R=value` (the equals form of the
  short `--repo` alias). `--repo=...` and `--hostname=...` were
  already covered; `-R=...` previously fell through to the generic
  flag branch and skipped the value.

- New tests for the symlink-aware canonicalisation: macOS-style
  `/var` ↔ `/private/var` mapping is mocked via vi.mock on
  node:fs, with cases for record-then-look-up under either form,
  generateNotePayload with a symlinked baseDir, partial clear via
  the canonical-root-derived path (deleted leaf), and snapshot
  restore canonicalisation.

- Doc-only: integration-test header comments updated from
  "V1 -> V2 -> V3" / "migration to V3" to reflect the actual V4
  end state (assertions already used the literal `4`).

* fix(shell): scope -m rewrite to commit segment, reject nested matches

Two Critical findings on addCoAuthorToGitCommit, plus a Copilot
maintainability nit:

- The `-m` regex used to scan the whole compound command, so
  `git commit -m "fix" && git tag -a v1 -m "release"` would target
  the LATER tag annotation (last -m wins) and splice the trailer
  there instead of the commit message. The rewrite now scopes to
  the actual `git commit` segment via a new
  findAttributableCommitSegment(): same shell-aware walk
  gitCommitContext does, but returning the segment's character
  range so the regex can be run on a slice and spliced back into
  the original command.

- Within the segment, a literal `-m '...'` *inside* a quoted body
  was treated as a real later -m. For
  `git commit -m "docs mention -m 'flag' for completeness"`, the
  inner single-quoted -m sits at a higher index than the real
  outer -m, and the previous index comparison would have it win —
  splicing the trailer mid-message and corrupting the quoting.
  The new code checks whether the candidate is nested inside the
  other quote-style's range (start/end containment) and prefers
  the outer match when so.

- Hoisted three constant Sets (sudo flag list, git global flags
  taking values, git global flags shifting cwd, gh global flags)
  out of the per-call scope to module constants. Functional
  no-op, but keeps the parsing helpers easier to read and avoids
  re-allocating the Sets on every command.

Two regression tests added for the cases above:
- inner `-m '...'` inside the outer message body is preserved
  literally and the trailer lands after the body
- `git tag -a v1 -m "release notes"` after a real
  `git commit -m "fix"` is left untouched, with the trailer
  appended to "fix" only

* fix(attribution): cd-leak, numstat partial failure, $() bailout, gh pr new alias

Five Critical/Suggestion items:

- `cd subdir && git commit` (or any non-attributable commit chain
  whose HEAD movement still happens in our cwd, e.g. cd into a
  subdirectory of the same repo) used to skip attribution AND fail
  to clear pending per-file entries. Those entries then leaked into
  the next foreground commit, inflating its AI percentage. New
  `else if (commitCtx.hasCommit)` branch in execute() compares pre-
  and post-HEAD; if HEAD moved we drop the per-file state. preHead
  is now snapshotted whenever ANY commit was attempted, not only
  attributable ones.

- getCommittedFileInfo's three diff calls run in `Promise.all`. If
  `--numstat` failed while `--name-only` succeeded, every file's
  diffSize would be 0 and generateNotePayload would clamp aiChars
  to 0 — emitting a structurally valid note with all-zero AI
  percentages. Detect the partial-failure shape (files non-empty,
  diffSizes empty) and return empty so no note is written.

- addCoAuthorToGitCommit and addAttributionToPR now bail when the
  captured `-m`/`--body` value contains `$(`. The tool description
  recommends `git commit -m "$(cat <<'EOF' ... EOF)"` for
  multi-line messages, but the regex's `(?:[^"\\]|\\.)*` body group
  stops at the first interior `"` from a nested shell token —
  splicing the trailer there breaks the command before it reaches
  the executor.

- looksLikeGhPrCreate now accepts `gh pr new` as well — it's a
  documented alias for `gh pr create` and was silently skipped.

- Removed `incrementPermissionPromptCount` / `incrementEscapeCount`
  and their getters: they had no production callers, so the backing
  fields just round-tripped through snapshots as 0. The four
  snapshot fields are now optional so pre-fix snapshots that carry
  non-zero values still load cleanly and just get ignored.

Three regression tests added: heredoc-style `-m "$(cat <<EOF...)"`
preserved literally, heredoc-style `--body` likewise, `gh pr new
--body "..."` rewritten with attribution.

* fix(attribution): --amend, --message/-b aliases, .d.ts over-exclusion

Four Copilot follow-ups, three of them user-visible coverage gaps:

- `git commit --amend` was diffing `HEAD~1..HEAD` for attribution,
  which spans the entire amended commit (parent → amended) rather
  than the actual amend delta. A message-only amend would emit a
  note attributing every file in the original commit to this
  amend. New `isAmendCommit` helper detects the flag and
  getCommittedFileInfo switches to `HEAD@{1}..HEAD` (the pre-amend
  HEAD vs the amended HEAD); if the reflog is GC'd we bail with a
  warning rather than over-attribute.

- `git commit --message "..."` and `--message="..."` were silently
  skipped because the regex only recognised the short `-m` form.
  The flag prefix now matches both alternatives via
  `(?:-[a-zA-Z]*m|--message)\s*=?\s*` (non-capturing inner group
  so the existing `[full, prefix, body]` destructure still works).

- `gh pr create -b "..."` (the short alias for `--body`) was the
  same gap on the PR side; `(?:--body|-b)[\s=]+` now covers both
  forms.

- `.d.ts` was an over-broad blanket exclusion in
  EXCLUDED_EXTENSIONS — declaration files are commonly authored
  (ambient declarations, asset shims like `*.d.ts` for
  `import './x.svg'`); the repo even contains
  `packages/vscode-ide-companion/src/assets.d.ts`. Removed `.d.ts`
  from the extensions Set and adjusted the test to assert the new
  behavior. Auto-generated `.d.ts` (e.g. `tsc --declaration`
  output) still gets caught by the build-directory rules.

Tests added: `--amend` plumbing covered by the new branch in
getCommittedFileInfo (no targeted unit test — the diff invocation
goes through ShellExecutionService and is exercised by the existing
post-command path); `--message`/`--message="..."`/-b/-b="..."` all
have positive trailer-injection assertions; `.d.ts` test split into
"hand-authored" (negative) and "in dist" (positive).

* fix(attribution): cd-subdir, scope --body, multi-commit count guard, /clear reset

Four bugs flagged this round:

- gitCommitContext / findAttributableCommitSegment used a blanket
  "any cd shifts cwd" gate, breaking the very common
  `cd subdir && git commit -m "..."` flow even though the commit
  lands in the same repo. New `cdTargetMayChangeRepo` heuristic:
  treat relative paths that don't escape upward (no leading `..`,
  no absolute path, no `~`/`$VAR` expansion, no bare `cd`/`cd -`)
  as in-repo and let attribution proceed. Conservative on anything
  it can't statically verify.

- addAttributionToPR was running the `--body`/`-b` regex against
  the FULL compound command string. In
  `curl -b "session=abc" && gh pr create --body "summary"` the
  regex would match curl's `-b` cookie flag and inject attribution
  into the cookie value, corrupting the curl call. Added
  `findGhPrCreateSegment` (analog of `findAttributableCommitSegment`)
  and scoped the body regex to that segment, splicing back into
  the original command via offsetting the in-segment match index.

- The multi-commit guard treated `runGitCount === 0` as "single
  commit" and bypassed itself. After `commitCreated === true`, a
  count of 0 is impossible in normal operation — it means
  rev-list errored or timed out. Now we bail on `commitCount !== 1`
  with a tailored message: anything other than exactly 1 commit
  is suspicious and refuses the note.

- The CommitAttributionService singleton survives across
  `Config.startNewSession()` (the `/clear` and resume paths). New
  `CommitAttributionService.resetInstance()` call alongside the
  existing chat-recording / file-cache resets in startNewSession
  prevents pending attributions from a prior session attaching to
  a commit in the new one.

Three regression tests added: `cd src && git commit` produces a
trailer (in-repo cd), `cd .. && git commit` does not (could escape
repo root), and `curl -b "..." && gh pr create --body "..."` leaves
curl's cookie value untouched while attribution lands in gh's body.

* fix(attribution): cd embedded .., env wrapper, Windows ARG_MAX, segment-locator warn

Four review items, all small but real:

- cdTargetMayChangeRepo missed embedded `..` traversal — `cd
  foo/../../escape` and similar would slip past the leading-`..`
  check and be treated as in-repo. Added an `includes('/..')` /
  `includes('\\..')` check (catches POSIX and Windows separators
  without false-positiving on `..` chars inside ordinary names,
  which only escape when followed by a separator).

- tokeniseSegment now recognises `env` as a safe wrapper alongside
  `sudo`/`command`, so `env GIT_COMMITTER_DATE=now git commit ...`
  resolves to `git`. After the wrapper detection we also skip any
  `KEY=VALUE` argv entries (env's own argument syntax for setting
  vars before the program).

- buildGitNotesCommand's MAX_NOTE_BYTES dropped from 128 KB to
  30 KB. Windows' CreateProcess lpCommandLine is capped around
  32,768 UTF-16 chars including the executable path and other argv
  entries; a 128 KB note would still fail to spawn even though
  the function returned a command instead of null. 30 KB leaves
  ~2 KB of headroom for the rest of the argv on Windows and is
  larger than any real commit's metadata in practice.

- findAttributableCommitSegment / findGhPrCreateSegment now log a
  debugLogger.warn when `command.indexOf(sub, cursor)` returns -1
  — splitCommands strips line continuations (`\<newline>`), so a
  multi-line command can have the trimmed segment text fail to
  match its source. Previously the segment was silently skipped
  with no signal; the warn makes the failure observable when
  QWEN_DEBUG_LOG_FILE is set.

Two regression tests added: `cd foo/../../escape && git commit`
gets no trailer (embedded-`..` heuristic catches it), and
`env GIT_COMMITTER_DATE=now git commit` does (env wrapper skipped).

* fix(attribution): scope isAmendCommit to attributable segment only

`git -C ../other commit --amend && git commit -m x` would previously
flag the second (fresh) commit as an amend, causing
attachCommitAttribution to diff `HEAD@{1}..HEAD` against an unrelated
reflog entry. Mirror findAttributableCommitSegment's cd/cwd tracking
so only the first commit segment that runs in the original cwd
determines amend status.

* fix(attribution): last-match --body, symlink leaf canonicalisation, scoped prompt count

- addAttributionToPR: use matchAll/last-match for `--body`/`-b` so the
  trailer lands in the gh-honoured (final) body when multiple flags are
  present. Mirrors addCoAuthorToGitCommit. Adds regression test.
- attachCommitAttribution: also fs.realpathSync the per-file resolved
  path (not just the repo root) so files behind intermediate symlinks
  are matched against canonical keys recordEdit stored, instead of
  silently zeroing attribution and leaking entries past commit.
- incrementPromptCount: scope to SendMessageType.UserQuery — ToolResult,
  Retry, Hook, Cron, Notification are model/background re-entries of
  the same logical turn. Tracking them all inflated the "N-shotted"
  trailer (one user message could become 10-shotted with 10 tool calls).
- AttributionSnapshot: add `version: 1` field; restoreFromSnapshot now
  refuses incompatible versions and validates per-field types so a
  partially-written snapshot can't seed `Math.min(undefined, n) === NaN`
  into git-notes payloads.
- Drop unused permission/escape counters (declared, persisted, never
  read or incremented) — fields, snapshot tolerance, and clear-method
  bookkeeping all removed; AttributionSnapshot interface simplifies.
- isGeneratedFile: switch directory rule from substring `.includes('/dist/')`
  to segment-boundary check (split on `/`) so project dirs like
  `my-dist/` or `xbuild/` don't match. `.lock` removed from the blanket
  extension exclusion — well-known lockfiles already covered by
  EXCLUDED_FILENAMES; hand-authored `.lock` files (e.g. `.terraform.lock.hcl`)
  now stay attributable.
- getClientSurface: document `QWEN_CODE_ENTRYPOINT` as the embedder
  override hook so the always-`'cli'` default is intentional.

* fix(attribution): skip values for env -u NAME and -S string

`env`'s value-taking flags (`-u`/`--unset`, `-S`/`--split-string`) were
not in the wrapper's flag-skip allowlist, so `env -u FOO git commit ...`
left FOO as the next token and the parser treated it as the program —
masking the real `git commit` from attribution detection. Add an
ENV_FLAGS_WITH_VALUE table mirroring the sudo allowlist. Regression
test added.

* fix(attribution): submodule leak, PR body nesting, shallow-clone bail, schema default

- attachCommitAttribution: when HEAD didn't move in our cwd, leave
  pending attributions alone instead of dropping them. The case can be
  a failed commit, `git reset HEAD~1`, OR `cd submodule && git commit`
  (inner repo's HEAD moves, ours doesn't). Dropping was overly
  aggressive and silently lost outer-repo edits in the submodule case.
- addAttributionToPR: mirror addCoAuthorToGitCommit's nested-match
  rejection so `gh pr create --body "docs mention -b 'flag'"` picks the
  outer `--body`, not the inner literal `-b`. Splicing into the inner
  match would corrupt the body. Regression test added.
- getCommittedFileInfo: when `rev-parse --verify HEAD~1` fails, also
  check `rev-list --count HEAD === 1` to confirm HEAD is the true
  root commit. In a shallow clone, HEAD~1 is unreadable but the commit
  has a parent recorded — falling back to `diff-tree --root` would
  diff against the empty tree and over-attribute the entire commit.
  Bail with a debug warning instead.
- generate-settings-schema: lift `default` (and `description`) out of
  the inner `anyOf[N]` schema to the outer level when wrapping with
  `legacyTypes`. Most JSON-schema-driven editors only surface
  top-level defaults; burying the default under `anyOf` lost the
  "enabled by default" hint. Also extend the default filter to
  publish non-empty plain objects (so `gitCoAuthor`'s default can
  appear). gitCoAuthor's source default updated to the runtime shape
  `{commit: true, pr: true}` to match `normalizeGitCoAuthor`.

* fix(attribution): drop unsafe full-clear, tag analysis-failure with null

ju1p (Copilot): the `else if (commitCtx.hasCommit)` branch fully
cleared the singleton on `cd /abs/same-repo/subdir && git commit`
(or `git -C . commit`), losing pending AI edits the user hadn't
staged. We can't tell which files were in the commit from this
branch, and the next attributable commit's partial-clear handles
cleanup correctly anyway. Drop the branch entirely.

ju2D (Copilot): `getCommittedFileInfo` returned the same empty
StagedFileInfo for both "could not analyze" (shallow clone, --amend
without reflog, --numstat partial failure, exception) and
"intentionally empty" (--allow-empty). The caller couldn't tell them
apart, so the partial clear became a no-op on analysis failure and
the just-committed AI edits leaked to the next commit. Switch the
return type to `StagedFileInfo | null` and have the caller treat
null as "fall back to full clear" while empty StagedFileInfo
(--allow-empty) leaves attributions intact for the next real commit.

* fix(attribution): dedup snapshot writes, cap excludedGenerated, doc commit toggle scope

rsf- (Copilot): recordAttributionSnapshot wrote a full snapshot to
the JSONL on every non-retry turn, even when the tracked state was
unchanged. Long-running sessions accumulated thousands of identical
snapshot copies, inflating session size and slowing /resume hydrate.
Dedup by JSON-equality with the prior write — first write always
goes through, identical successors are no-ops.

rsgo (Copilot): excludedGenerated path list was unbounded. A commit
churning thousands of generated artifacts (large dist/ rebuild)
could push the JSON note past MAX_NOTE_BYTES (30KB) and lose
attribution for the real source files in the same commit. Cap the
serialized sample at MAX_EXCLUDED_GENERATED_SAMPLE (50) and add
excludedGeneratedCount for the true total.

rsg9 + rshM (Copilot): the gitCoAuthor.commit description claimed
the toggle only controlled the Co-authored-by trailer, but
attachCommitAttribution also gates the per-file git-notes payload
on the same flag. Update both the schema description and the
settings.md table to mention both effects so disabling the option
isn't a silent surprise.

* fix(attribution): depth-1 shallow detection, snapshot dedup post-rewind/post-failure

sfGz (Copilot): rev-list --count HEAD === 1 cannot distinguish a
true root commit from a depth-1 shallow clone — both report 1
because rev-list only walks locally available objects. Switch to
git log -1 --pretty=%P HEAD which reads the parent SHA directly
from commit metadata: empty means a real root, non-empty means a
parent is recorded (whether or not its object is local). The
shallow-clone bail is now reliable.

sfIm (Copilot): the dedup key persisted across rewindRecording, so
the previous snapshot living on the now-abandoned branch would
match the next post-rewind snapshot and silently skip the write,
leaving /resume on the rewound session with no attribution state.
Reset lastAttributionSnapshotJson when rewindRecording fires.

sfJE (Copilot): dedup key was committed before the async write
settled. A transient write failure would update the key, then
permanently suppress all future identical snapshots even though
nothing was ever persisted. Switch to optimistic-set then rollback
on appendRecord rejection — synchronous identical calls dedup
cleanly, but a failed write clears the key so the next identical
snapshot retries. appendRecord now returns the per-record write
promise (writeChain still has its swallow-catch for chain liveness)
so callers needing per-write success can react to it. Tests added
in chatRecordingService.test.ts for both rewind-reset and
rollback-on-failure paths.

* fix(attribution): preHead race, regex apostrophe-escape, surface failures, dead code

t2G0 (deepseek-v4-pro): addCoAuthorToGitCommit single-quote regex now
matches the bash close-escape-reopen apostrophe form using
((?:[^']|'\\'')*) — the same pattern bodySinglePattern uses for
gh pr create. Input like git commit -m 'don'\''t' was previously
silently un-rewritten because the negative lookahead bailed; the
trailer now lands at the FINAL closing quote. Test updated.

tMBP (gpt-5.5): preHead capture switched from concurrent async
getGitHead to a synchronous getGitHeadSync (execFileSync) BEFORE
ShellExecutionService.execute spawns the user's command. A fast
hot-cached git commit could move HEAD before the async rev-parse
resolved, leaving preHead === postHead and silently skipping the
attribution note. Trade ~10–50 ms event-loop block per
commit-shaped command for correctness of the post-command HEAD
comparison.

t2Gv (deepseek-v4-pro): attribution write failures (note exec
non-zero, payload too large, diff-analysis exception, shallow
clone / amend-without-reflog) are now surfaced on the shell tool's
returnDisplay AND llmContent so the user and agent both see when
their commit succeeded but the per-file git note didn't land.
attachCommitAttribution now returns string | null (warning text or
null for intentional skips like no-tracked-edits). Co-authored-by
trailer is unaffected — only the note is gated by these failures.

t2Gy (deepseek-v4-pro): committedAbsolutePaths now matches against
the canonical keys already stored in fileAttributions
(matchCommittedFiles iterates by relative path against the
canonical repo root) instead of re-resolving each diff path
on the fly. realpathSync(resolved) failed for deleted files and
didn't follow intermediate symlinks, leaving stale per-file
attribution alive past commit and inflating AI percentages on
subsequent commits.

t2HI (deepseek-v4-pro): removed dead sessionBaselines /
FileBaseline / contentHash / computeContentHash infrastructure
(~40 lines). The fields were written, persisted, and restored but
never read for any computation or decision. AttributionSnapshot
schema stays at version 1 — restore tolerates pre-fix snapshots
that carried the now-ignored baselines field.

t2HM (deepseek-v4-pro): extracted the duplicated lastMatch helper
in addCoAuthorToGitCommit and addAttributionToPR into a single
module-level lastMatchOf so future fixes can't be applied to only
one copy.

* chore(schema): regenerate settings.schema.json to match gitCoAuthor.commit description

The settingsSchema.ts source for `gitCoAuthor.commit.description` was
updated in 3c0e3293b but the JSON schema only picked up the OUTER
description rewrite and missed this inner property's. The Lint check
("Check settings schema is up-to-date") fails on that drift; this
commit re-runs `npm run generate:settings-schema` to sync them.

* fix(attribution): preserve unstaged AI edits across cleanup branches

uxU5 + uxVQ + uxUO (Copilot): every cleanup branch in
attachCommitAttribution that called clearAttributions(true) was
wholesale-erasing pending AI edits for files the user never staged
in this commit. Reviewer scenarios:
- multi-commit chain (`commit a && commit b`) bails out without
  writing a note, but unstaged edits to file Z (touched by neither
  commit) get cleared along with the chain's committed files.
- attribution toggle off: same — toggling the flag wipes pending
  unstaged work.
- analysis failure (shallow clone, --amend without reflog, partial
  diff failure): the finally-block fallback wholesale-cleared
  every pending file, consuming unrelated AI edits.
- 0%-AI commit: when no file in the commit was AI-touched,
  generateNotePayload was emitting an "0% AI" note attached to a
  commit that legitimately had no AI involvement — actively
  misleading metadata.

Add `noteCommitWithoutClearing()` to the service: snapshots the
prompt counter as the new "at last commit" but leaves the per-file
map alone. Use it in the multi-commit, no-tracked-edits,
toggle-off, and analysis-failure paths. The committed-files
partial-clear (clearAttributedFiles) still runs in the success
path. The 0%-AI no-match case now skips the note write entirely.

* fix(attribution): runGit null-on-failure, versionless v3→v4 migration

z54M (Copilot): runGit returned '' on both successful-empty-output
and silent failure, so a `--name-only` that errored mid-way through
the diff fan-out aliased to a real `--allow-empty` commit. The
empty-commit branch then preserved pending attributions, leaving
the just-committed file's tracked AI edit alive to re-attribute on
the next commit. Switch runGit to `Promise<string | null>`,
distinguishing exit code 0 (any output, including '') from non-zero
(null). The diff-stage fan-out and ancillary probes now treat null
as analysis failure and bail with `return null` instead of falling
into the empty-commit path.

z539 (Copilot): the v3→v4 `shouldMigrate` only fired on
`$version === 3`. A versionless settings file carrying the legacy
`general.gitCoAuthor: false` boolean would skip every migration
(gitCoAuthor isn't in V1_INDICATOR_KEYS — it post-dates V2), get
its `$version` normalized to 4 by the loader, and leave the
boolean in place. The settings dialog then reads the V4
`{commit, pr}` shape, sees missing keys, defaults both to true, and
silently overwrites the user's opt-out on the next save. Also fire
when `$version` is absent AND the value at `general.gitCoAuthor`
is a boolean. Tests cover the new path and confirm the existing
versioned/object-shape paths are untouched.

* fix(attribution): toggle-off partial clear, normalizeGitCoAuthor type-check, terraform lockfile

0oAK (Copilot): the gitCoAuthor.commit toggle-off branch returned
before computing the committed file set, leaving the just-committed
files' tracked AI work in the singleton. Re-enabling the toggle and
committing the same file again would re-attribute earlier (already-
committed) AI edits to the new commit. Move the toggle gate AFTER
matchCommittedFiles so the finally block does a proper partial clear
of the just-committed files even when the note write is skipped.

0oAg (Copilot): normalizeGitCoAuthor copied value?.commit / value?.pr
without type-checking. settings.json is hand-editable; a stored
`{ commit: "false" }` reached runtime as a truthy string and behaved
as if attribution were enabled. Add a per-field bool coercion that
falls back to the schema default (true) for any non-boolean,
matching what the dialog and IDE schema already imply. Tests cover
the string / number / null cases.

0oAo (Copilot): v3→v4 shouldMigrate only special-cased versionless
legacy booleans — versionless files with invalid gitCoAuthor values
(`"off"`, `[]`, etc.) skipped the migration and the loader stamped
`$version: 4` over the bad value. Runtime normalization then
silently re-enabled attribution. Extend shouldMigrate to fire on ANY
versionless non-object value at general.gitCoAuthor; the existing
migrate() body's drop-and-warn path resets it. Already-object
shapes (hand-edited to v4) still skip cleanly. Tests added.

0oAt (Copilot): `.terraform.lock.hcl` got dropped from generated-file
exclusion when `.lock` was removed from the blanket extension list
in 3c0e3293b. It's a generated provider lockfile in the same class
as `package-lock.json` and dominates Terraform-repo commits. Re-add
to EXCLUDED_FILENAMES and add a regression test covering both
repo-root and module-nested locations.

* fix(attribution): harden restoreFromSnapshot against corrupt payloads

1KMY (Copilot): snapshot.surface was copied without type validation.
A corrupted/partially-written snapshot with a non-string surface
(e.g. {}, 42, null) would later be serialized into the git note as
"[object Object]" and used as a Map key downstream, breaking the
expected payload shape. Type-check and fall back to the current
client surface for any non-string (or empty-string) value.

1KLq (Copilot): per-field sanitiseCount enforced
`promptCount >= 0` and `promptCountAtLastCommit >= 0` independently,
but never the cross-field invariant. A snapshot with
promptCountAtLastCommit > promptCount would surface a negative
getPromptsSinceLastCommit() and propagate as a "(-N)-shotted"
trailer into PR text. Clamp atLastCommit to total on restore.

1KL_ (Copilot): when a snapshot carried both the symlinked and
canonical paths for the same file (a session straddling the
canonicalisation fix), `set(realpathOrSelf(k), ...)` overwrote the
first entry with the second, silently dropping the AI contribution
the first form had accumulated. Merge instead: sum aiContribution
and OR aiCreated when collapsing duplicate keys.

Tests cover all three branches: non-string surface fallback,
promptCount clamp, and duplicate-key merge.

* fix(attribution): roll back snapshot dedup key on sync appendRecord failure

1UMh (Copilot): appendRecord can throw synchronously before returning
a promise — e.g. when ensureConversationFile() rethrows a non-EEXIST
writeFileSync error. The async .catch() handler attached to the
promise never runs in that case, so the optimistic dedup-key set
sticks on a write that never landed and permanently suppresses
identical retries. Roll back lastAttributionSnapshotJson in the outer
catch too. Regression test forces writeFileSync to throw EACCES on
the first invocation, then asserts the second identical snapshot
attempt fires a fresh write rather than getting deduped.

* docs(attribution): align cleanup-branch comments with noteCommitWithoutClearing

Three doc/test-fixture stale-after-refactor cleanups (Copilot
4MDx / 4MEI / 4MEa):

- shell.ts:1944 (around the stagedInfo === null branch): the comment
  still claimed the finally block "falls back to a full clear", but
  1ece87438 switched analysis-failure cleanup to
  noteCommitWithoutClearing(). Update the comment so the reasoning
  matches what the code actually does (and so a future reader doesn't
  reintroduce the wholesale clear thinking it's already there).

- shell.ts: getCommittedFileInfo docstring carried the same stale
  "full clear" claim for the `null` return value. Update to describe
  the noteCommitWithoutClearing() fallback and the smaller-evil
  trade-off for the just-committed file.

- chatRecordingService.test.ts: baseSnapshot fixture for the
  recordAttributionSnapshot tests still carried `baselines: {}`,
  even though that field was removed from AttributionSnapshot in
  296fb55ae's dead-code purge. Structural typing let it compile,
  but the fixture didn't reflect the production shape — drop it.

* fix(attribution): restore fire-and-forget appendRecord, route rollback via callback

6OcJ (Copilot): refactor in 715c258fb returned a Promise from
appendRecord so the snapshot dedup-key path could chain rollback —
but recordUserMessage / recordAssistantTurn / recordAtCommand /
recordSlashCommand / rewindRecording all call appendRecord without
await or .catch(). A transient jsonl.writeLine rejection on any of
those would surface as an unhandled-promise-rejection (warning, or
crash on --unhandled-rejections=throw).

Restore the original fire-and-forget semantics: appendRecord again
returns void and internally swallows async failures (logging via
debugLogger). Per-record failure reactions are routed through an
optional onError callback — recordAttributionSnapshot uses this to
roll back lastAttributionSnapshotJson when the write that set it
ends up rejecting.

Tests: add a fire-and-forget regression that mocks writeLine to
reject and asserts no unhandledRejection events fire while the
existing snapshot rollback tests (sync + async) still pass via the
new callback path.

* fix(attribution): GIT_DIR repo-shift bail, snapshot envelope validation, narrow legacyTypes

80ME (gpt-5.5 /review, [Critical]): tokeniseSegment unconditionally
stripped every leading KEY=value token. `GIT_DIR=elsewhere/.git git
commit ...` was therefore treated as an in-cwd commit, picked up the
Co-authored-by trailer, and produced a per-file note that landed
against our cwd's HEAD even though the actual commit went to a
different repo. Define a GIT_ENV_SHIFTS_REPO set (GIT_DIR,
GIT_WORK_TREE, GIT_COMMON_DIR, GIT_INDEX_FILE, GIT_NAMESPACE) and
have tokeniseSegment refuse to parse any segment whose leading env
block (including the env-wrapper's KEY=VALUE block) carries one of
these. Identity / date variables (GIT_AUTHOR_*, GIT_COMMITTER_*) are
deliberately NOT in the set — they tweak metadata but don't relocate
the repo. Tests cover plain prefix, env-wrapped prefix, and a
GIT_COMMITTER_DATE positive control that should still get the trailer.

8EeQ (Copilot): restoreFromSnapshot received `snapshot as
AttributionSnapshot` from a structural cast off `unknown` (the
resume path), so its TS-typed shape was only a hint. A corrupted
JSONL line (non-object / array / wrong type discriminator / missing
type) would skip past the version check straight into
Object.entries(snapshot.fileStates) — and a non-object fileStates
(an array, say) seeded fileAttributions with numeric-string keys.
Add envelope-level shape gates (isPlainObject + type discriminator)
and a fileStates plain-object check before iterating; both bail to a
clean reset rather than poisoning the singleton. Tests added.

8Eej (Copilot): SettingDefinition.legacyTypes was typed as
SettingsType[] which includes 'enum' and 'object' — JSON Schema's
`type` keyword doesn't accept those values. Adding
`legacyTypes: ['enum']` would silently produce an invalid
settings.schema.json. Narrow the field's type to
ReadonlyArray<'boolean' | 'string' | 'number' | 'array'> (the
JSON-Schema-primitive subset). Future complex-shape legacy support
should land its own branch in convertSettingToJsonSchema.

* docs(attribution): correct legacyTypes / EXCLUDED_DIRECTORY_SEGMENTS comments

9Ta_ (Copilot): the JSDoc on legacyTypes claimed JSON Schema's
`type` keyword does not accept `'object'` — that's wrong; `'object'`
IS a valid JSON Schema type. Reword to reflect the actual rationale:
`'enum'` is not a valid JSON Schema `type` value at all (enum
constraints use the `enum` keyword), and a bare `{type: 'object'}`
would accept any object regardless of what the field's pre-expansion
shape actually allowed. The narrowed `boolean | string | number |
array` set is exactly what the one-liner generator can faithfully
emit; richer legacy shapes belong in their own branch of
convertSettingToJsonSchema.

9Tbs (Copilot): the comment in generatedFiles.ts referenced
`EXCLUDED_DIRECTORIES`, but the constant is `EXCLUDED_DIRECTORY_SEGMENTS`
(renamed during the segment-boundary refactor). Update the
reference so a future maintainer scanning for the rule doesn't
chase a non-existent identifier.

* fix(attribution): SHA-pin git notes, on-disk hash divergence detection, env -C cwd-shift

tanzhenxin review #1 — Note targets symbolic HEAD, not captured SHA:
buildGitNotesCommand hard-coded 'HEAD' as the target; postHead was
captured at commit-detection time but only used for the !== preHead
diff. Between that capture and the execFile, three more awaited git
calls run — anything that moves HEAD in the same cwd (post-commit
hook, chained `commit && tag -m`, parallel process) silently lands
the note on the wrong commit because of `-f`. Thread postHead
through buildGitNotesCommand as a required `targetCommit` arg.
Test asserts the targeted SHA, not the symbolic ref.

tanzhenxin review #2 — Accumulator has no baseline:
recordEdit was monotonic per-path with no reset for out-of-band
mutations. Re-instate FileAttribution.contentHash and:
- recordEdit hashes the input `oldContent` and resets the per-file
  accumulator if it doesn't match what AI's last write recorded
  (catches paste-replace via external editor, manual save, etc.
  WHEN AI subsequently edits the same file again).
- New validateOnDiskHashes() rehashes every tracked file's CURRENT
  on-disk content and drops entries whose hash diverged. Called
  from attachCommitAttribution before matchCommittedFiles so a
  commit can never credit AI for a human-only diff. Deleted files
  (readFileSync throws) are left alone — the commit's deletion
  record is what the note should reflect.

tanzhenxin review #4 — Failed-commit / staleness leak:
The recordEdit divergence check above + commit-time
validateOnDiskHashes together catch tanzhenxin's exact scenario
(AI edits a.ts → hook rejects → user manually edits a.ts → user
commits → no AI credit because validateOnDiskHashes drops the
stale entry). The !commitCreated branch still preserves
attributions to keep the submodule case working — the staleness
problem is now solved at the next commit's validation step.

Self-review item — env -C / --chdir treated as repo-shifting:
Added ENV_FLAGS_SHIFT_CWD set covering -C / --chdir. tokeniseSegment
returns null for `env -C DIR git commit ...` segments — same
contract as a leading GIT_DIR=... assignment. Without this we'd
either misidentify /elsewhere as the program (silently dropping
attribution) or, worse if -C went into the value-skip set,
trailer-inject onto a commit that lands in /elsewhere's repo. Tests
added alongside the existing GIT_DIR repo-shift cases.

339 tests pass; typecheck clean.

* fix(attribution): pickBool intent-aware, shouldClear gate, ETIMEDOUT surface, drop dead exports

-wgA + -wg0 (deepseek): pickBool defaulted non-boolean to true,
turning a hand-edited `{ commit: "false" }` into enabled
attribution. Replace with intent-aware parsing: "true"/"yes"/"on"/
"1" → true, "false"/"no"/"off"/"0"/"" → false, anything else
(unknown strings, non-1 numbers, objects, arrays, null) → false.
Genuinely-absent sub-fields still default to true (schema default).
Migration test scenarios covered. Tests now cover ~17 input cases
across both string/number/null/object/unknown forms.

-wgq (deepseek): when buildGitNotesCommand returned null (oversized
payload) or git notes itself failed, the finally block called
clearAttributedFiles(committedAbsolutePaths) — irreversibly
deleting per-file attribution data the user might need to amend &
retry. Introduce a separate `shouldClear` set that's only assigned
on successful note write OR explicit toggle-off. Failure paths
(oversized, exitCode != 0, exception, analysis failure) leave
shouldClear null so the finally block calls noteCommitWithoutClearing
instead — preserving per-file state for the user's recovery.

9p7W (Copilot): execFile callback coerced ETIMEDOUT / SIGTERM
(timeout) into a generic exitCode=1 warning. Detect both
`error.code === 'ETIMEDOUT'` and `error.killed === true &&
error.signal === 'SIGTERM'` so the user-visible warning correctly
names "timed out after 5s" instead of "exited 1".

-wg7 (deepseek): formatAttributionSummary and getAttributionNotesRef
were exported but had zero production callers (only tests). Remove
the dead exports + their tests (~40 LOC). If/when a logging surface
needs them, they can be re-introduced.

-wgb (deepseek): tokeniseSegment doesn't recursively unwrap
`bash -c '...'` / `sh -c` / `zsh -c`, so addCoAuthorToGitCommit
won't splice the trailer into a wrapped command. The background
refusal AND the post-commit note path DO catch the wrapped commit
because stripShellWrapper at the top of execute peels the wrapper
before gitCommitContext / getGitHead run — so the worst-case
("background bash -c 'git commit' bypasses the guard") doesn't
materialize. The remaining gap (no Co-authored-by trailer for
bash -c-wrapped commits) requires recursively splicing into the
inner script with proper bash single-quote re-quoting; significant
enough that it's worth its own PR. Documented as a partial-coverage
limitation.

339 → 325 tests pass after the dead-export removal; typecheck clean.

* fix(attribution): committed-blob validation, deleted-leaf canonicalisation, sudo/env shifts, dir-stack

gpt-5.5 review (issue 4389405179):

1. realpathOrSelf falls back to the non-canonical input when the
   leaf doesn't exist (deleted file). recordEdit stored the entry
   under the canonical path; lookup post-deletion misses on macOS
   where /var ↔ /private/var. Canonicalise the parent and rejoin
   the basename for missing leaves so deleted-file getFileAttribution
   still resolves the canonical key. Test updated to assert the
   lookup-after-unlink path explicitly.

2. validateOnDiskHashes read the LIVE working-tree, so a user who
   `git add`'d AI's content and then made additional unstaged edits
   would have the entry dropped on a commit whose blob still matched
   AI's hash. Replace with `validateAgainst(getContent)` that takes
   a caller-supplied reader; attachCommitAttribution now passes a
   reader that fetches the COMMITTED blob via `git show HEAD:<rel>`.
   Working-tree validation kept as `validateAgainstWorkingTree` for
   code paths without a committed ref. Returns null = no comparison
   signal (entry preserved). Tests cover all three readers
   (committed-blob via stub, working-tree, null-passthrough).

deepseek-v4-pro review #1: sanitiseAttribution defaults missing
contentHash to '' on legacy-snapshot restore. recordEdit's
divergence check would then trip on every subsequent edit and
silently reset all the AI work. Skip the divergence check when
existing.contentHash is empty — we have no baseline to compare
against, so don't drop. Test added covering legacy-snapshot
preservation through validateAgainst.

deepseek #4: validateAgainst now logs every entry drop via
debugLogger.debug so a 3am operator can see WHICH entry got
dropped and tied to which canonical key.

deepseek #8: GIT_NAMESPACE removed from GIT_ENV_SHIFTS_REPO. It
prefixes ref names within the same repo but doesn't redirect git
to a different on-disk repository, so a commit underneath it still
lands in our cwd's repo. Doc comment explains the distinction.

deepseek #9: pushd/popd treated as cwd-shifting alongside cd in
gitCommitContext / isAmendCommit / findAttributableCommitSegment.
pushd reuses cdTargetMayChangeRepo (relative-no-escape stays
in-repo); popd unconditionally flips cwdShifted because we don't
track the bash dir-stack.

deepseek #10: sudo's value-taking flag table now has a parallel
SUDO_FLAGS_SHIFT_CWD set covering -D / --chdir (Linux sudo 1.9.2+).
Any segment whose sudo wrapper sees one of those flags returns null
from tokeniseSegment — same contract as env -C / --chdir and
GIT_DIR=...

328 tests pass; typecheck clean both packages.

* fix(attribution): scope validateAgainst to committed set, SHA-pin reader, intent-aware migration

Round 1 of multi-pass audit on b3a06a7c4. Three correctness fixes:

1. validateAgainst was iterating ALL fileAttributions but the
   committed-blob reader (git show HEAD:<rel>) returns HEAD's
   pre-AI content for files NOT in the just-made commit. Result:
   pending unstaged AI work was silently wiped on every commit
   because the divergence check ran against the wrong baseline
   for unrelated files. Fix: build the committed scope first via
   matchCommittedFiles, scope the reader to that set (return null
   for everything else), validate, then RE-run matchCommittedFiles
   to pick up dropped entries. The validateAgainstWorkingTree
   wrapper had no production caller — removed it and its test.

2. The committed-blob reader used symbolic `HEAD` instead of the
   captured postHead SHA — same TOCTOU concern buildGitNotesCommand
   already addressed. A post-commit hook moving HEAD between
   capture and the reader's `git show` would silently compare
   against the wrong commit's content and trip the divergence
   check spuriously. Pin the reader to `git show <postHead>:<rel>`.

3. v3→v4 migration's invalid-string fallback used to reset to {}.
   Combined with the runtime pickBool's "absent → schema default
   true" rule, that silently re-enabled attribution for users who
   hand-edited `"gitCoAuthor": "off"` to disable. Migration now
   recognises enable-intent strings (true/yes/on/1/enabled) and
   disable-intent strings (false/no/off/0/disabled/'') and maps
   them to {commit, pr} explicitly. Unrecognised strings fall to
   {commit: false, pr: false} with a warning — same safer-by-default
   contract as runtime pickBool. Test grid covers all 11 cases.

Also tidied the FileAttribution.contentHash JSDoc to reference
the renamed `validateAgainst` (was still pointing at the dropped
`validateOnDiskHashes` name).

1085 tests pass; typecheck clean both packages.

* chore(attribution): extract pickOuterLastMatch, log unrecognised pickBool inputs

Round 2 of multi-pass audit. Two cleanups, no behaviour changes:

1. addCoAuthorToGitCommit and addAttributionToPR each carried their
   own copy of the matchRange / isInside / "pick LAST non-nested
   match" logic (~25 LOC duplicated). Extracted to module-level
   helpers `matchSpan`, `isMatchInside`, and `pickOuterLastMatch<T>`
   so a future bug fix can't apply to only one of the two
   rewriters. Behaviour identical — same algorithm, same edge cases.

2. normalizeGitCoAuthor's pickBool silently maps unrecognised
   strings to false (safer-by-default vs the old "default-to-true
   on mismatch" policy, but a user who hand-edited
   `{ commit: "maybe" }` had no signal that their setting was being
   ignored). Add a `gitCoAuthorLogger.warn` listing the accepted
   forms so a debug-mode user can see the actual coercion. Known
   disable-intent strings (false/no/off/0/empty) stay silent —
   they're explicit user intent. Also pass the field name so the
   warning identifies which sub-toggle (commit vs pr) was bad.

1101 tests pass; typecheck clean.

* fix(attribution): canonicalise BOM and CRLF before hashing

Round 3 of multi-pass audit. One real correctness fix.

Edit and WriteFile preserve the file's BOM and CRLF line-ending
choice when writing back, so the on-disk bytes can include a leading
U+FEFF and CRLFs even when AI's recordEdit input was given with LF
and no BOM. The committed-blob reader's `git show <sha>:<rel>`
returns those raw bytes verbatim, and computeContentHash hashed them
as-is — so a UTF-8 BOM file or a CRLF-line-ending file would always
have a mismatch between AI's recorded hash and the on-disk hash, and
validateAgainst would drop the entry on every commit.

Add `canonicaliseForHash`: strips a leading U+FEFF and normalises
CRLF→LF before computing the SHA-256. Both sides (recordEdit when
storing the post-write hash, and validateAgainst when comparing to
the on-disk read) flow through computeContentHash, so the
canonicalisation is symmetric. The hash is metadata used only for
divergence detection — collapsing these visual differences is the
right comparison semantics.

Three regression tests added: BOM-only, CRLF-only, and BOM+CRLF
combined. All exercise the typical case where AI's recordEdit input
is LF + no BOM but the on-disk content (post-writeTextFile) has the
file's preserved BOM/lineEnding choice.

* fix(attribution): reset accumulator when re-creating a deleted tracked file

Round 4 of multi-pass audit + Copilot finding from review 4236842362
(I missed it in the previous refresh).

recordEdit's existing prior-state check was symmetric on diverged
oldContent but ASYMMETRIC on a fresh file lifetime: when AI creates
`foo.ts` (oldContent=null), then user `rm foo.ts`, then AI
re-creates `foo.ts` (oldContent=null again), the second recordEdit
saw `existing` (from the first lifetime) and SKIPPED the divergence
check (because oldContent === null bails out of that branch). The
accumulator carried 100 chars from the deleted file plus 5 chars
from the new content = 155, vs the actual 5 on disk. Subsequent
generateNotePayload's clamp against `(adds+dels) * 40` couldn't
catch this — the diff size for a 1-line addition is 40, far above
the actual content size.

Add a fresh-file-lifetime branch: when `existing` is set AND the
caller reports `oldContent === null`, reset aiContribution and
aiCreated before counting the new contribution. The new edit is
treated as a brand-new file at the same path (which is what the
caller's null oldContent means semantically).

Test added covering the exact `AI create → delete → AI re-create`
flow. Also verified `should treat new files as ai-created` and
`should accumulate contributions across multiple edits` still pass.

* fix(attribution): treat git -C . as in-cwd, gate preHead on attributable

Round 5 of multi-pass audit. Two related correctness/efficiency
fixes around the cwd-shift parser and the preHead capture.

1. `git -C .` (and `-C ./`, `-C.`) is a no-op cwd shift but the
   "any -C → cwd-shifted" rule was treating it the same as
   `-C /tmp/other`, suppressing attribution for what's effectively
   `git commit` with an explicit current-dir marker. Add an
   `isNoopCwdTarget` helper used in both the spaced (`-C .`) and
   attached (`-C.`) branches of `parseGitInvocation`. `--git-dir`
   / `--work-tree` are left unconditional — those aren't cwd in the
   same sense.

2. preHead was being captured for ANY hasCommit, including the
   non-attributable cases (`cd /elsewhere && git commit`,
   `git -C /other commit`). The only consumer of preHead is the
   `attachCommitAttribution` call inside the `attributableInCwd`
   branch — there is intentionally NO cleanup branch for the
   non-attributable case (see the existing comment around the
   `else if (commitCtx.hasCommit)` non-branch). The execFileSync
   for `getGitHeadSync` is dead work in that path: ~10–50 ms
   blocking the event loop before the user's real command spawns.
   Gate the capture on `attributableInCwd` to match the consumer.

Tests added for the three -C dot-form variants. Full suite green:
146 in shell.test.ts, 56 in commitAttribution.test.ts.

* fix(core): preserve attribution across renamed files

* fix(attribution): preserve env-vars in tokens, exclude empty -C targets

Round 7 of multi-pass audit. Two related fixes around how
`shell-quote` handles env-var references and how the cwd-shift
detector reads them.

1. `shell-quote.parse` collapses `$NAME` references it cannot
   resolve to the empty string. The downstream cwd-shift checks
   (`cdTargetMayChangeRepo`'s `target.includes('$')` repo-shift
   detector, and the new `isNoopCwdTarget` no-op detector) were
   designed to catch env-var targets but received `''` instead of
   `$NAME` from `tokeniseSegment` and silently failed. Concretely,
   `cd $HOME && git commit` and `git -C $HOME commit` would both
   pass through as in-cwd attributable, stamping our trailer onto
   commits that land in whatever repo `$HOME`/`$REPO_ROOT`
   resolves to at runtime.

   Pass an env getter `(key) => '$' + key` to `shell-quote.parse`
   inside `tokeniseSegment` so unresolved references stay literal
   in tokens (`['cd', '$HOME']` instead of `['cd', '']`).
   `target.includes('$')` now fires correctly, and the no-op
   detector sees `$HOME` (non-`.`) and rejects it. KEY=value
   leading-env detection is unaffected (shell-quote doesn't
   interpolate inside KEY=value tokens).

2. Even with env preservation, an `''` target can still slip
   through (literal `-C ""`, escaped quotes, edge cases in
   shell-quote). Round 5's `isNoopCwdTarget` accepted `''` as a
   no-op alongside `'.'` / `'./'`, which would re-introduce the
   attribution-on-wrong-repo problem if any path produced an
   empty token. Tighten to `'.'` and `'./'` only — the only
   missed cases are literal `-C ""` (malformed, won't actually
   commit) and the rare `-C $PWD` (now also caught conservatively,
   since `$PWD` becomes literal `$PWD` and isn't `.` or `./`).

Tests added for `cd $HOME` / `cd $REPO_ROOT && git commit` and
`git -C $HOME commit` / `git -C "" commit`. Full suite green
(150 in shell.test.ts, 58 in commitAttribution.test.ts).

* fix(attribution): SHA-pin diff/rev-list phase, document aiChars heuristic

Addresses tanzhenxin's review (4240760004) — two residuals after
the prior pinning round.

1. Diff phase still races against HEAD.

   The note write itself was already pinned to the captured `postHead`
   (`git notes add -f <postHead>`), but the *content* of the note —
   `getCommittedFileInfo`'s probe + diff calls and the multi-commit
   guard's `rev-list --count` — were still going through symbolic
   `HEAD` / `HEAD~1` / `HEAD@{1}`. Several awaited subprocesses run
   between the postHead capture and these reads, so a husky / lefthook
   auto-amender, signed-commits hook, chained `git tag -m`, or
   parallel git process moving HEAD in that window would leave the
   note attached to commit A but describing commit B's contents.
   Same TOCTOU class as the prior critical, half-closed.

   Thread `postHead` (and `preHead` for amend) through
   `getCommittedFileInfo`. Probes become `rev-parse --verify
   ${postHead}~1` and `log -1 --pretty=%P ${postHead}`; diffs become
   `${postHead}~1..${postHead}` (parent case),
   `${preHead}..${postHead}` (amend — preHead is the pre-amend SHA
   captured before the user's command and is exactly what HEAD@{1}
   resolved to at parse time, with the added benefit that it can't be
   GC'd between capture and use), and `diff-tree --root <postHead>`
   (root commit). The amend branch keeps the existing reflog-vs-
   no-reflog warning, just driven off `preHead` instead of HEAD@{1}.

   Same pin applied to `countCommitsAfter` (now `${preHead}..
   ${postHead}`) and `countCommitsFromRoot` (now `${postHead}`).

   Why parent case uses `${postHead}~1` and NOT `${preHead}`: in
   `git reset HEAD~3 && git commit` chains the captured preHead
   points well above postHead's parent, and `${preHead}..${postHead}`
   would describe the reset-away commits as deletions, drastically
   over-attributing. The actual parent of the just-landed commit is
   what we want, and `${postHead}~1` is the SHA-pinned form of that.

2. `aiChars` reads as a literal char count but isn't.

   The field is emitted as a plain integer named `aiChars`; the PR
   description's example shows values like 3200 / 1500 / 4700 that
   anyone parsing the note will read as literal character counts.
   Internally it's `(addedLines + deletedLines) × 40` for text and a
   flat 1024 for binary, with the per-file AI accumulator clamped
   against that ceiling. So 1000 one-character lines and 1000
   thousand-character lines both report aiChars=40000, and a 5 MB
   image change and a 1-byte binary tweak both report 1024. Anyone
   aggregating raw aiChars for compliance reporting gets
   systematically wrong numbers.

   Add a comprehensive doc block on `FileAttributionDetail` (and
   `CommitAttributionNote`) calling out the heuristic explicitly,
   noting that `percent` / `summary.aiPercent` are the correct
   fields for aggregation since both numerator and denominator use
   the same proxy. Also expand the `APPROX_CHARS_PER_LINE` /
   `BINARY_DIFF_SIZE_FALLBACK` const docs to point at the same
   caveat. (Not renaming the fields — that'd break any downstream
   consumer already parsing the existing schema; the doc is the
   minimum-disruption call here.)

208 attribution tests pass; type-check clean.

* fix(attribution): use posix join in applyCommittedRenames for Windows compat

Windows CI failure on the two new rename tests (visible at PR #3115's
`Test (windows-latest, *)` jobs):

  AssertionError: expected undefined to be defined
  ❯ src/services/commitAttribution.test.ts:572:66 (basic move)
  AssertionError: expected 11 to be 22 (merge into existing)

Root cause: `path.join(canonicalRepoRoot, ...renamedRel.split('/'))`
calls `path.win32.join` on Windows, which forces backslash separators
regardless of input form. The test's `fs.realpathSync` mock returns
forward-slash paths (matching the macOS `/var` ↔ `/private/var`
fixture style), so `recordEdit` stores keys like
`/private/var/repo/src/old.ts`. The rename's joined target then came
out as `\\private\\var\\repo\\src\\new.ts`, the mock left it
unchanged (no `/var/` prefix to translate), and the subsequent
`fileAttributions.get(renamedAbs)` / `getFileAttribution(...)` lookups
missed the just-set entry — the rename silently dropped attribution.

The fix: build the joined path with `path.posix.join` against a
forward-slash-normalised `posixRepoRoot`, then let `realpathOrSelf`
canonicalise to the platform's storage form. This way:

  - On real Windows production: posix-joined `D:/repo/src/new.ts` is
    accepted by `fs.realpathSync` (Win32 API takes mixed slashes) and
    returned in backslash form, matching what `recordEdit` stored.
  - On real Linux/macOS production: forward-slash throughout, no-op.
  - In the symlink-aware test (any platform): forward-slash matches
    the mock-fixture storage form.

`matchCommittedFiles` already does the inverse normalisation
(`.split(path.sep).join('/')` for the relative-form check), so the
in/out paths line up either way.

Skipped adding a path.sep-mocked Linux-side regression because the
ESM module namespace doesn't allow `vi.spyOn` on path's exports.
The Windows CI job is the regression catcher; a focused-rerun
should now go green.

* docs(attribution): refresh stale HEAD~1/HEAD@{1} references in comments

The SHA-pinning round (8c3312027) replaced symbolic `HEAD~1..HEAD` /
`HEAD@{1}..HEAD` with `${postHead}~1..${postHead}` and
`${preHead}..${postHead}` in `getCommittedFileInfo` and the rev-list
helpers, but three docstrings / inline comments still described the
old shapes:

- `isAmendCommit` JSDoc said the amend switch goes from `HEAD~1..HEAD`
  to `HEAD@{1}..HEAD`. Updated to reference `${postHead}~1..${postHead}`
  and `${preHead}..${postHead}`, with the why (amended commit's parent
  is the original's parent so the standard parent diff lumps both
  commits' changes).
- `attachCommitAttribution`'s amend branch comment had the same drift;
  updated to mention `${preHead}..${postHead}` directly.
- `getCommittedFileInfo` JSDoc said it diffs "HEAD against its parent
  (HEAD~1)" and listed "--amend with no reflog" as an analysis-failure
  case. Updated to mention postHead-pinning and the preHead-driven
  amend bail (the reflog-GC dependency was dropped in the SHA-pin
  round).

The remaining `HEAD~1..HEAD` references at countCommitsAfter:1959 and
getCommittedFileInfo:2523 are intentional — they describe the old
buggy shape as contrast for why we pin now.

No code change; tests + tsc still clean.

* fix(attribution): catch attached-value forms of env/sudo cwd-shift flags

Round 13 audit found a real bug: `sudo --chdir=/tmp git commit`,
`env -C/tmp git commit`, `env --chdir=/tmp git commit`, and
`sudo -D/tmp git commit` were all silently slipping through the
cwd-shift detector and getting our `Co-authored-by` trailer stamped
onto commits that landed in a different repo.

Root cause: `shell-quote` tokenises both the long attached form
(`--chdir=/tmp`) and the short attached form (`-C/tmp`) as a single
argv entry. The previous SHIFT_CWD detector did set-membership only
against the bare flag (`{'-C', '--chdir'}` for env;
`{'-D', '--chdir'}` for sudo), so the attached-form tokens never
matched and `tokeniseSegment` returned a normally-attributable
`['git', 'commit', ...]` segment.

Fix: introduce `isShiftCwdFlag(flag, set)` that catches:
  - bare set-membership (existing behavior),
  - long attached: `--name=...` when `--name` is in the set,
  - short attached: `-Xanything` when `-X` is in the set and the
    token is longer than the flag itself.

The flag does NOT need to consume an extra value token in the
attached-form case (the value is already embedded), so the existing
TAKES_VALUE bookkeeping is unaffected — we just bail with `null`
from `tokeniseSegment` before reaching the value-skip step.

Tests added: `env --chdir=`, `env -C/...` (attached), `sudo --chdir=`,
`sudo -D/...` (attached) — each is asserted NOT to add a co-author
trailer. 154 shell tests pass; type-check + lint clean.

* test(attribution): cover attached-form git -C/--git-dir/--work-tree

Adds three regression cases to the existing "git -C <path>" suppression
test: the short attached form `-C/path` (single shell-quote token)
and the long attached forms `--git-dir=/path` / `--work-tree=/path`.
parseGitInvocation already had the prefix checks at lines 416/425, but
no test exercised them — paired with the b89b65533 sudo/env attached-
form fix this round closes the family of "shell-quote single-token
flag with embedded value" cases that the bare set-membership checks
would otherwise miss.

157 shell tests pass; type-check clean.

* docs(attribution): document why backtick body doesn't bail like $(

The addCoAuthorToGitCommit body capture has a known truncation case
when an inner unescaped `"` appears inside the captured body — handled
for `$(...)` command substitution with an explicit bailout, but not
for backtick command substitution. The trade-off was unspoken; spell
it out so a future reviewer doesn't read the asymmetry as an
oversight.

Bare-backtick bodies (`\`func()\`` markdown-style) are common in
commit messages, have no inner `"`, and the regex captures them
correctly. Pathological backtick-with-inner-quote bodies (`\`cmd
"with" quotes\``) are a near-zero-traffic case where bash itself
already interprets the backticks as command substitution, so the
user has likely already broken their own command before our rewrite
runs. Bailing on any backtick would lose attribution for the common
case to defend against the rare one.

Also drops a stray blank line in commitAttribution.test.ts left over
from an earlier regression-test attempt.

* fix(attribution): scope trailer rewrite to before unquoted shell comment

Round 13 follow-on. Both `addCoAuthorToGitCommit` and
`addAttributionToPR` ran their `-m` / `--body` regex against the full
segment string, including any trailing shell comment. For a command
like `git commit -m "real" # -m "fake"` (a human-authored script
might leave a comment-out flag in place), `lastMatchOf` would pick
the comment's `-m "fake"`, splice the `Co-authored-by:` trailer in
there, and bash would silently discard the entire segment as a
comment — leaving the actual commit unattributed. Same shape for
`gh pr create --body "real" # --body "fake"`.

Fix: introduce `findUnquotedCommentStart(s)` — a bash-aware position
scanner that tracks single/double-quote state and treats `#` as a
comment marker only when it begins a word (start of input or
preceded by whitespace), not when it appears inside a quoted region
or mid-token like `foo#bar`. Both rewriters slice the segment to
`[0, commentStart)` before running their regex, so the trailer can
only land in the live (pre-comment) part.

Tests added:
  - `git commit -m "real" # -m "fake"` — trailer lands in `"real"`
    body BEFORE the `#`, comment's `-m "fake"` is left untouched.
  - `git commit -m "fix #123 add feature"` — `#` inside the quoted
    body is correctly NOT treated as a comment; the `#123` stays
    inside the body and the trailer is appended.

159 shell tests pass; type-check clean.

* fix(attribution): warn on gh pr create flows that can't be rewritten + cover legacy gitCoAuthor migration end-to-end

Two residuals from this morning's review pass.

1. ANm7O — `addAttributionToPR` silently skipped for `--body-file`,
   `--fill`, and bare `gh pr create` (editor) flows.

   The rewriter only knows how to splice into an inline `--body`/`-b`
   argv entry. For a `gh pr create` that uses `--body-file path`,
   `--fill` (uses commit messages), or no body flag at all (editor
   prompt), there's no inline body to splice into and the function
   returned the unmodified command. Users with `gitCoAuthor.pr`
   enabled would see PRs created without the attribution line and
   have no signal as to why.

   Add a debugLogger.warn at the no-match path naming the unsupported
   flows and pointing the user at the inline form. Don't try to
   handle `--body-file` automatically — that would mean mutating the
   user's file on disk, which is well outside what an unprompted
   command rewriter should do; `--fill` and editor flows have no body
   in argv at all and can't be rewritten without re-architecting.

   Tests added for `--body-file <path>`, `--fill`, and bare
   `gh pr create` — each is asserted to leave the command unchanged
   (no `Generated with Qwen Code` line spliced in).

2. ANm7L — settings-migration integration suite didn't cover the
   exact V3 legacy shape this PR introduces.

   `v3-to-v4.test.ts` already pins the migration body, but the end-
   to-end CLI load → migrate → write path could regress without the
   integration suite noticing. The existing v3LegacyDisableSettings
   fixture has no `general.gitCoAuthor` field, so the V3→V4 step
   technically fires but doesn't exercise the new boolean-expansion
   logic.

   Add a `v3GitCoAuthorBooleanSettings` fixture and a paired test
   case that writes `general: { gitCoAuthor: false }` at $version 3,
   runs the same `mcp list` CLI invocation, and asserts the saved
   file has $version 4 plus `general.gitCoAuthor` exactly
   `{ commit: false, pr: false }` — with sibling general.* keys and
   unrelated top-level sections preserved.

162 shell tests pass; type-check + lint clean.

feat(cli): customize banner area (logo, title, hide) (#3710)
* docs(design): add banner customization design (#3005)

Document the design for issue #3005 (customize CLI banner area). Covers
the banner region taxonomy and what is replaceable vs. locked, the three
proposed settings (`ui.hideBanner`, `ui.customBannerTitle`,
`ui.customAsciiArt`) and their resolution pipeline, the schema additions
and wiring touch points, five alternative shapes considered, and the
security / failure-handling guards. Mirrored EN + zh-CN under
`docs/design/customize-banner-area/`. No code changes in this commit;
implementation lands in a follow-up PR.

* feat(cli): customize banner area (logo, title, hide)

Adds three opt-in `ui.*` settings that let users replace brand chrome on
startup while keeping the operational lines (version, auth, model, path)
locked: `hideBanner`, `customBannerTitle`, `customAsciiArt` (string,
{path}, or {small,large}).

A new resolver in `packages/cli/src/ui/utils/customBanner.ts` walks the
loaded settings, normalizes each tier per scope (so {path} resolves
against the file that declared it), reads the file with O_NOFOLLOW and a
64 KB cap on POSIX, sanitizes via a banner-specific stripper that drops
OSC/CSI/SS2/SS3 sequences while preserving newlines, and caps art at 200
lines × 200 cols and titles at 80 chars. Every soft failure logs a
`[BANNER]` warn and falls through to the bundled QWEN logo or default
brand title — banner config can never crash the CLI.

`<Header />` now picks the widest custom tier that fits via a shared
`pickAsciiArtTier` helper and falls back to `shortAsciiLogo` otherwise;
`<AppHeader />` extends the existing `showBanner` gate to honor
`hideBanner` alongside the screen-reader fallback.

Tracks #3005 and the design merged in #3671.

* docs(design): apply prettier to banner customization design

Reformats the EN and zh-CN design docs in
`docs/design/customize-banner-area/` to satisfy `npx prettier --check`:
table column alignment and trailing commas in `jsonc` examples. No
content changes — the words, tables, and code blocks all say the same
thing as before.

Carries forward the only actionable feedback from the now-closed
docs-only PR #3671, where the prettier check was the sole change
requested.

* fix(cli): address banner audit findings

Three audit-driven fixes for the banner customization feature:

1. **VSCode JSON schema accepts every documented shape.** The
   `ui.customAsciiArt` entry in
   `packages/vscode-ide-companion/schemas/settings.schema.json` was
   declared as `type: object`, which made VSCode flag the inline-string
   form (`"customAsciiArt": "  ___"`) — a shape the runtime accepts and
   the design doc recommends — as a schema violation. Replaced with a
   `oneOf` covering string, `{path}`, and `{small,large}` (with each
   tier itself string-or-`{path}`).

2. **Narrow terminals no longer leak the QWEN logo over a white-label
   deployment.** When a user supplied custom ASCII art but neither tier
   fit the terminal, `Header.tsx` previously fell back to the bundled
   `shortAsciiLogo` — silently undoing the white-label intent on small
   windows. The fallback now distinguishes "user supplied custom art"
   from "no custom art at all": in the first case the logo column is
   hidden entirely (info panel still renders); in the second case the
   default logo shows as before. Soft-failure paths (missing file,
   sanitization rejection) still fall through to `shortAsciiLogo`.

3. **Sanitizer strips C1 control bytes (0x80-0x9F).** The art and title
   strippers previously stopped at 0x7F, leaving single-byte CSI
   (`0x9B`), DCS (`0x90`), ST (`0x9C`) and other C1 controls intact —
   which legacy 8-bit terminals would still interpret. Aligned the
   ranges with the repo's existing `stripUnsafeCharacters` (in
   `textUtils.ts`) so banner content can't carry interpreted control
   bytes through.

New tests cover: C1 strip in art and title, absolute path reads,
symlink rejection on POSIX, narrow-terminal hide-on-custom-art, and
end-to-end `<AppHeader />` rendering through `resolveCustomBanner`.
The full banner suite is 48 tests (was 42).

* docs(design): clarify cross-scope tier merge and white-label fallback

Two clarifications surfaced by the audit on the implementation PR:

1. The design said `customAsciiArt` follows standard merge precedence,
   but the resolver actually walks scopes per-tier so workspace can
   override only `large` while user keeps `small`. Document that this
   per-tier walk is intentional — both because each `{path}` has to
   resolve against the file that declared it (the merged view loses
   that information) and because it lets users keep a personal default
   tier and override the other one per-workspace.

2. The render-time tier-selection step now distinguishes "user
   supplied custom art but neither tier fits" (hide the logo column
   entirely; falling back to `shortAsciiLogo` would silently undo a
   white-label deployment on narrow terminals) from "user supplied no
   custom art at all" (fall through to `shortAsciiLogo` and let the
   default-logo width gate decide). Step 5's pure soft-failure
   fallback (missing file, sanitization rejection) is unchanged —
   still `shortAsciiLogo`.

* docs(design): add size budget section to banner customization

Question raised on the implementation PR: "why is the test logo `CCA`
instead of the full `Custom Code Agent` — is there a character limit?"

There is no character-count limit on titles or art. There is a
**width budget** driven by terminal columns, plus an absolute
hard cap (200×200 art, 80-char title) to keep malformed input from
freezing layout. The existing user-facing guide didn't quantify the
budget anywhere, so users were guessing why long inline names didn't
render.

Add a "How wide can the logo be? — the size budget" subsection that
spells out the formula
(`availableLogoWidth = terminalCols − 4 − 2 − 44`), tabulates it at
80 / 100 / 120 / 200 cols, calls out that a 17-char brand like
"Custom Code Agent" can't render as a single ANSI Shadow line on most
terminals (~120 cols of art), and shows the stacked-words
`{ small, large }` recipe — including the `figlet` one-liner that
generates the corresponding `banner-large.txt`.

* docs(design): add limits-at-a-glance table; switch demo to Custom Agent

The banner-customization design now has the size budget written down,
but the per-cap limits (80-char title, 200×200 art, 64 KB file) were
buried inside the size-budget formula table. Surface them as their own
"Limits at a glance" subsection at the top of the user-configuration
guide so users see the hard caps before they start hand-crafting art.

Also switch the running example from "Custom Code Agent" (17 chars,
~120 cols of ANSI Shadow art on one line — too wide for any common
terminal) to "Custom Agent" (12 chars, two-word stack at ~54 cols ×
12 lines, fits any terminal ≥ 104 cols). The figlet recipe is now a
two-word pipeline so a copy-paste run produces art the size the doc
claims.

Mirrored both changes in the zh-CN translation. The implementation
itself is unchanged.

* fix(cli): address PR review + CI Lint failure

Two reviewer findings on PR #3710 (and the Lint job that fails for the
same root cause):

1. **Schema regen now reproduces the committed JSON Schema.** The CI
   Lint step runs `npm run generate:settings-schema` and fails when
   the worktree dirties — my earlier hand-authored `oneOf` got blown
   away because `customAsciiArt` is `type: 'object'` in the source
   schema and the generator had no way to emit a union.

   Add a `jsonSchemaOverride` escape-hatch field on `SettingDefinition`:
   when set, the generator emits the override verbatim (description
   carried forward) instead of the type-driven shape. Set it on
   `customAsciiArt` to express the runtime union (string | {path} |
   {small,large} where each tier is itself string-or-{path}). The
   committed schema is now regenerated from source and CI's
   regenerate-and-diff check passes; two back-to-back regens produce
   identical output.

2. **Untrusted workspace settings no longer influence the banner.**
   `collectScopedTiers()` walked `settings.workspace` directly because
   per-scope file paths are needed to resolve relative `{path}`
   entries — but that bypassed the trust gate that
   `settings.merged` enforces. An untrusted checkout could therefore
   render its own ASCII art and trigger local file reads through a
   `{path}` entry before the user trusts the folder. Skip
   `settings.workspace` entirely when `settings.isTrusted` is false.
   Two regression tests cover the gate (untrusted = workspace
   silenced, falls through to user; trusted = workspace honored).

Test suite for the banner is now 30 resolver tests + the existing
Header / AppHeader / settingsSchema tests = 66 total, all green.

* feat(cli): add ui.customBannerSubtitle for the spacer row

Adds a fourth opt-in setting to the banner customization surface.
The info panel renders four rows (title, subtitle/spacer, status,
path); the second row was a hard-coded single-space spacer up to
now. With this change a fork or white-label deployment can set
`ui.customBannerSubtitle` to a one-line subtitle (e.g. "Built-in
DataWorks Official Skills") and have it render in the secondary
text color in place of the spacer. Empty/unset preserves the
previous blank-spacer layout, so the change is back-compat.

The subtitle is sanitized through the same
`sanitizeSingleLine` helper as the title (now factored out): OSC /
CSI / SS2 / SS3 leaders dropped, every other C0/C1 control byte
replaced with a space, internal whitespace collapsed, ends
trimmed. Capped at 160 characters — looser than the title's 80
because tagline / "powered by" copy commonly runs longer — with
the same `[BANNER]` warn on truncation.

Wiring:

- `settingsSchema.ts` — new `customBannerSubtitle` entry next to
  `customBannerTitle`, `showInDialog: false` (free-form text in
  the TUI dialog isn't worth its own picker).
- `customBanner.ts` — `ResolvedBanner.subtitle` field;
  `resolveCustomBanner` populates it; `sanitizeTitle` and the new
  `sanitizeSubtitle` share the same helper.
- `Header.tsx` — when `customBannerSubtitle` is truthy the spacer
  row renders the string (secondary color, single line) instead
  of `<Text> </Text>`. Auth/model and path still sit at their
  usual positions.
- `AppHeader.tsx` — pipes `resolvedBanner.subtitle` through.
- VSCode JSON schema regenerated from source (idempotent).

Tests: 5 new resolver tests (default, sanitize, length cap,
empty, newline + C1 strip), 2 new Header tests (renders subtitle
between title and auth; spacer preserved when unset), 1 new
AppHeader integration test (end-to-end through resolver). Banner
suite is now 35 + 17 + 6 + 16 = 74 tests, all green.

Design docs (EN + zh-CN) updated: region taxonomy now lists four
B-rows; "Limits at a glance" table grows a subtitle row;
"Customization rules" matrix and "How to modify" section gain a
"Add a brand subtitle" example with a rendered four-row preview.

* docs(design): sweep stale 3-setting references after subtitle add

Self-review found several sections of the banner customization design
doc still framed for the original three settings; bring them in line
with the four-setting reality landed in c7aa4a401:

- Region taxonomy ASCII diagram now shows four B-rows
  (① title, ② subtitle, ③ status, ④ path).
- Resolution-pipeline ASCII diagram and step list pick up
  customBannerSubtitle on the input side and the title/subtitle
  sanitize step on the resolver side.
- "Settings schema additions" section lists the fourth entry,
  customBannerSubtitle, and notes the customAsciiArt
  jsonSchemaOverride that landed for VS Code schema reproducibility.
- "Wiring changes" section updates the Header prop list and the
  HeaderProps interface, replaces the brittle line-number anchors
  with file-level anchors, drops the obsolete `paths` second arg
  from resolveCustomBanner, and adds the trust-gate sentence.
- "Security & failure handling" table replaces the
  stripTerminalControlSequences shorthand with the actual
  banner-specific stripper, splits the title/subtitle row to cover
  both, and adds the untrusted-workspace gate as its own row.
- "Verification plan" gains two scenarios: the subtitle row, and
  the untrusted-workspace check that the Critical reviewer comment
  on the impl PR explicitly asked us to lock down.

Mirrored every edit in the zh-CN translation. The implementation
itself is unchanged.

* fix(cli): address banner re-review (FIFO, mutex schema, display width, regex dedupe)

Addresses the five findings on PR #3710 from the latest re-review:

1. **[Critical] FIFO/pipe at `customAsciiArt.path` no longer hangs
   startup.** The resolver was calling `openSync(path, O_NOFOLLOW)`
   *before* the `fstatSync(...).isFile()` check; on POSIX, opening a
   FIFO read-only blocks until a writer connects, and `O_NOFOLLOW`
   doesn't help — it only refuses symlinks at the final path
   component. `readArtFile` now `lstatSync()`s first and refuses
   non-regular files (FIFO / socket / device / symlink) before the
   open, while keeping the post-open `fstatSync` check for TOCTOU
   safety against a swap between the lstat and the open. New
   POSIX-only regression test `mkfifo`s a named pipe and asserts the
   resolver soft-fails inside 1 s; if the open ever regresses to
   blocking, the test will hang past the timeout and the assertion
   will catch it.

2. **[Suggestion] `{path}` and `{small,large}` are now mutually
   exclusive in both schema and runtime.** The `jsonSchemaOverride`
   on `ui.customAsciiArt` is split into three branches (string,
   `{path}`, `{small?, large?}`); none of them allow `path` and tier
   keys to co-exist. `normalizeTiers()` mirrors that — an object
   carrying both kinds of keys is now soft-rejected with a `[BANNER]`
   warn rather than letting `path` silently win and dropping the
   tier values. New regression test pins the runtime side.

3. **[Suggestion] Column cap and tier-fit selection now measure in
   terminal cells.** `getAsciiArtWidth` (in `textUtils.ts`) and the
   `MAX_ART_COLS` cap in `customBanner.ts` were both using UTF-16
   `.length`, so 200 CJK fullwidth characters would slip the cap and
   render at ~400 cells, and `pickAsciiArtTier`'s width-fit check
   was wrong for any non-ASCII art. Switched both to
   `getCachedStringWidth` (string-width semantics, already in the
   repo); art truncation walks code points until adding another
   would push the cell width past the cap, so we never split a
   fullwidth code point or surrogate pair down the middle. New
   regression test exercises the CJK fullwidth case.

4. **[Suggestion] `collectScopedTiers()` no longer drops a whole
   scope just because it has no `file.path`.** Inline-string tiers
   don't need an owning settings directory; only `{path}` tiers do.
   The path-presence check was moved into the `{path}` branch, so a
   path-less scope (e.g. `systemDefaults`, future SDK-injected
   scopes) can still contribute inline art. `{path}` entries in such
   a scope soft-fail with a tier-specific `[BANNER]` warn rather
   than killing the whole scope. Two regression tests cover both
   sides.

5. **[Suggestion] OSC / CSI / SS2-3 regex are now authored once.**
   Extracted `TERMINAL_OSC_REGEX`, `TERMINAL_CSI_REGEX`,
   `TERMINAL_SHIFT_DCS_REGEX` from `stripTerminalControlSequences`
   in `@qwen-code/qwen-code-core` and re-export them from the
   package index. `customBanner.ts` reuses the constants for
   `sanitizeArt` (which still has to preserve `\n` / `\t`) and
   delegates the title/subtitle pipeline directly to
   `stripTerminalControlSequences`. Also backported the C1 control
   strip (0x80-0x9F) into the core helper so all callers
   (session-title, etc.) benefit from the same coverage; banner
   sanitizer was the only place catching single-byte CSI / DCS / ST.

Banner suite is now 40 + 17 + 6 + 16 = 79 tests, all green. Schema
regen is still byte-for-byte idempotent. `npm run typecheck` and
prettier clean on touched files.

* fix(cli): replace require() with ES6 import in FIFO test (lint)

The FIFO regression test in 7ccbfaeb1 used a synchronous `require()` to
pull in `node:child_process` so the test could lazy-load `execFileSync`
only when needed. CI Lint flagged it under `no-restricted-syntax` —
the repo enforces ES6 imports throughout, including in tests, with no
exception for `require()`.

Move the import to the top of the file alongside the other `node:` /
vitest imports. The `try/catch` around `execFileSync('mkfifo', ...)`
still gates the test on `mkfifo` being available (rare on a fresh
container, so we skip rather than fail). 40 / 40 tests still pass and
ESLint is clean on the touched file.

get-release-version.js scripts into a shared module at
scripts/lib/release-helpers.js so that changes only need to happen
in one place.

Also fixes a pre-existing bug in getArgs where argument values

fix(cli): bound SubAgent display by visual height to prevent flicker (#3721)
* fix(cli): bound SubAgent display by visual height to prevent flicker

The SubAgent runtime display used hard-coded MAX_TASK_PROMPT_LINES=5 and
MAX_TOOL_CALLS=5 plus character-length truncation (`length > 80`). On narrow
terminals the soft-wrapped content overflowed the available height as the
tool-call list grew, forcing Ink to clear and redraw on every update.

Pull AgentExecutionDisplay onto the same visual-height/visual-width slicing
pattern that ToolMessage and ConversationMessages already use:

- Add `sliceTextByVisualHeight` to textUtils — counts soft wraps as visual
  rows, supports top/bottom overflow direction.
- AgentExecutionDisplay now derives maxTaskPromptLines / maxToolCalls from
  the assigned `availableHeight` and uses `truncateToVisualWidth` (CJK +
  emoji safe) instead of substring(0, 80). Compact mode is unchanged.
- Drop the 300 ms debounced `refreshStatic` AppContainer fired on every
  terminalWidth change — that was a flicker source on resize and the
  static area no longer needs the refresh.

Tests:
- textUtils.test.ts covers undefined maxHeight, top/bottom overflow, and
  soft-wrap counting.
- AgentExecutionDisplay.test.tsx asserts the height-bounded render keeps
  the prompt + tool list inside the assigned rows.
- AppContainer.test.tsx asserts width-only changes no longer clear the
  terminal.

* test(tui): add SubAgent flicker regression script and ANSI counter

Two reusable tools for measuring TUI flicker:

- `scripts/measure-flicker.mjs` — standalone Node script that counts the
  ANSI escape sequences which betray flicker (clearTerminalPair, clearScreen,
  eraseLine, cursorUp) inside any recorded raw stream (`script` log,
  `tmux pipe-pane` output, custom PTY capture). Supports baseline diff mode.

- `integration-tests/terminal-capture/subagent-flicker-regression.ts` —
  end-to-end ratchet that boots a mock OpenAI server, drives a real qwen
  process through an `agent` tool dispatch + 5 `read_file` SubAgent rounds,
  then reads PTY bytes and asserts ANSI-redraw counts stay below configured
  ceilings. Mirrors PR #43f128b20's resize-clear-regression pattern.

Reference numbers (60-col / 18-row terminal, fixed build):
  clearTerminalPair=5, clearScreen=10, eraseLine=440, cursorUp=132

The ratchet defaults to 10/20 ceilings — roughly 2× steady state — so
regressions like reverting sliceTextByVisualHeight or restoring the
width-driven refreshStatic trip the build.

Implementation notes captured in the script's docstring:
  - Strips HTTP_PROXY family env vars (NO_PROXY isn't honored by undici,
    so corp proxy would otherwise hijack the loopback request).
  - Drops `--bare` (bare mode hard-codes the registered tool set and
    rejects the `agent` tool); HOME is sandboxed to a temp dir instead.
  - Mock server speaks SSE because the CLI requests stream:true.

* fix(cli): address inline review on SubAgent flicker fix

Three issues from inline review on PR #3721:

1. **availableHeight as total budget (Critical).** The previous formula
   only constrained prompt + tool-call height, not the surrounding
   header / section labels / gaps / footer. Default and verbose mode
   could still overrun the parent-provided budget. Subtract a fixed-row
   overhead (10 rows running, 18 completed) before computing
   `maxTaskPromptLines` / `maxToolCalls`. Add unit tests that assert the
   rendered frame line-count stays within `availableHeight` for both
   running and completed states.

2. **Ratchet that actually distinguishes fix from no-fix.** The previous
   `clearTerminalPair` / `clearScreen` ceilings passed for both fixed
   and unfixed builds. Add an `eraseLine` upper bound (default 460) —
   that's the metric whose drop reflects the in-place-update efficiency
   the visual-height fix delivers (no-fix observed 469, with-fix 434).
   Refresh docstring with the current numbers and a coverage map that
   honestly states what this ratchet does and does not exercise.

3. **Keypress scope.** `useKeypress` was active on every mounted
   `AgentExecutionDisplay`, including completed/historical instances in
   chat history — Ctrl+E / Ctrl+F would toggle them all in lock-step
   and cause large scrollback reflows. Gate `isActive` on
   `data.status === 'running'`. Test mock now also honors
   `{ isActive }` so the new "completed displays ignore Ctrl+E"
   regression is enforceable.

* fix(cli): address round-2 inline review on SubAgent flicker

Three follow-up issues from inline review on PR #3721:

1. **sliceTextByVisualHeight reservedRows early-return (Critical).**
   The early return compared `visualLineCount <= targetMaxHeight` and
   ignored `reservedRows`, so a caller asking us to keep one row free
   for a footer could still receive the full input back with
   `hiddenLinesCount: 0` even though only `targetMaxHeight - reservedRows`
   content rows were actually available. Compare against
   `visibleContentHeight` instead and add a regression test for the
   `'a\nb\nc' / 3 / reservedRows: 1` case the reviewer flagged.

2. **Footer hint and rendered prompt now share one slicing result
   (Suggestion).** Previously `hasMoreLines` looked at
   `data.taskPrompt.split('\n').length` (hard newlines only), but the
   prompt body was already truncated by `sliceTextByVisualHeight` (which
   counts soft wraps). A long single-line prompt could be visually
   truncated without the footer ever surfacing the "ctrl+f to show
   more" hint. Lift the slice into the parent component and feed both
   the rendered `TaskPromptSection` and the footer's `hasMoreLines`
   from the same `hiddenLinesCount`.

3. **Running → completed transition test (Critical).** The previous
   "completed displays ignore Ctrl+E" test rendered already-completed
   data, so `useKeypress` was inactive from the start and Ctrl+E was a
   no-op trivially. It missed the real path: a running subagent gets
   expanded, then completes while preserving the expanded
   `displayMode` — which is exactly when the completed-state budget
   has to hold the layout. Replace the test with a `rerender`-based
   one that runs the full transition, asserts the completed expanded
   frame stays within `availableHeight`, and asserts the post-transition
   Ctrl+E is a no-op. Bumped `COMPLETED_FIXED_OVERHEAD` from 18 to 22
   to accommodate the ExecutionSummary + ToolUsage block accounting
   that the new transition test exposed.

* fix(cli): gate SubAgent useKeypress on isFocused for parallel runs

Per @yiliang114's review on PR #3721 — `data.status === 'running'` alone
fixes the historical/scrollback case but two SubAgents running in parallel
both stay `running`, so a single Ctrl+E / Ctrl+F still toggles them in
lock-step and the dual reflow brings back the flicker the gating was meant
to prevent. The component already receives `isFocused` from ToolMessage
(via SubagentExecutionRenderer) for the inline confirmation prompt — reuse
it on the keypress hook:

  isActive: data.status === 'running' && isFocused

Adds a regression test that renders a running SubAgent with
`isFocused={false}` and asserts Ctrl+E is a no-op (frame unchanged).

feat(cli): add API preconnect to reduce first-call latency (#3318)
Fire a fire-and-forget HEAD request early in startup to warm the TCP+TLS connection. Subsequent SDK calls share an undici dispatcher with preconnect, reusing the warmed connection to save 100-200ms on the first request.

Skip conditions:
- NODE_EXTRA_CA_CERTS set (enterprise TLS inspection)
- Sandbox mode (process-restart context)
- Non-default baseUrl (mTLS / private deployment)
- Non-Node runtimes (Bun)

fix(test): update rewind E2E Test 1 assertion after isRealUserTurn fix (#3622)
Test 1 asserted `say exactly GAMMA3` after pressing Up once in the
rewind selector, but that only passed because `/rewind` was incorrectly
counted as a user turn. After `isRealUserTurn()` excluded slash commands,
the turn list is [ALPHA1, BETA2, GAMMA3] and Up from the initial
selection (GAMMA3) lands on BETA2. Update the assertion to match.

feat(cli): add conversation rewind feature with double-ESC and /rewind command (#3441)
* feat(cli): add conversation rewind feature with double-ESC and /rewind command (#3186)

Add the ability to rewind conversation to a previous user turn, similar
to Claude Code's message selector. Users can trigger rewind via:
- Double-ESC on empty prompt while idle
- /rewind (or /rollback) slash command

The RewindSelector component provides a two-phase UI: a scrollable
pick-list of user turns followed by a confirmation dialog. On confirm,
both UI history and API history are truncated consistently, the terminal
is re-rendered, and the original prompt text is pre-populated in the
input for editing.

Key implementation details:
- historyMapping.ts correctly handles tool-call loops (functionResponse
  entries) and the startup context pair when mapping UI turns to API
  Content[] indices
- useDoublePress hook provides generic double-press detection with
  800ms timeout and proper cleanup on unmount
- ESC handler guards against WaitingForConfirmation state to prevent
  accidental rewind during tool approval
- Chat recording service records rewind events with tree-branching
  via parentUuid for session replay support

Closes #3186

* fix: call recordRewind() in handleRewindConfirm and simplify payload

- Actually invoke chatRecordingService.recordRewind() after rewind
- Remove tree-branching from recordRewind (no UI-to-recording UUID
  mapping exists yet) to avoid corrupting the parentUuid chain
- Simplify RewindRecordPayload to just truncatedCount

* fix(rewind): resolve resume persistence and IDE mode issues

- chatRecordingService: add turnParentUuids tracking and rewindRecording()
  which re-roots the parentUuid chain so rewound messages land on a dead
  branch; reconstructHistory() then skips them automatically on resume.
  Add rebuildTurnBoundaries() for re-populating the index after /resume.
- AppContainer: fix truncatedCount bug (was always 0 after loadHistory),
  wire handleRewindConfirm to rewindRecording() with correct targetTurnIndex,
  add config.getIdeMode() guard to openRewindSelector so rewind is disabled
  in IDE sessions where extra user Content entries break the API boundary
  mapping.
- useResumeCommand: call rebuildTurnBoundaries() after startNewSession so
  rewind works correctly within resumed sessions.
- resumeHistoryUtils: surface "Conversation rewound." info item when a
  rewind record is encountered during history reconstruction.
- historyMapping.test.ts: add 9 unit tests for computeApiTruncationIndex
  covering normal flow, startup context pair, tool responses, and
  compression fallback.
- Copyright headers: standardize new files to "Copyright 2025 Qwen Code".

* fix(rewind): close slash-command, compression, and IDE bypass holes

Three bugs found by Codex review:

1. P1: `/rewind` slash command bypassed the IDE-mode guard because
   `slashCommandActions.openRewindSelector` called `setIsRewindSelectorOpen`
   directly. Fixed by introducing a ref bridge (`openRewindSelectorRef`)
   that delegates to the guarded callback.

2. P1: Slash-command invocations (`/help`, `/stats`, etc.) are stored as
   `type: 'user'` in UI history but never reach the API or recording
   service. The turn-index counter in `handleRewindConfirm` and
   `computeApiTruncationIndex` counted them, producing off-by-N errors.
   Added `isRealUserTurn()` helper that excludes items starting with
   `/` or `?`, applied in all three counting sites (AppContainer,
   historyMapping, RewindSelector).

3. P2: After chat compression, `computeApiTruncationIndex` returned
   `apiHistory.length` when the target turn was unreachable, silently
   keeping the full API history while the UI was truncated. Changed to
   return `-1`; `handleRewindConfirm` now aborts with an error message
   when the target turn was absorbed by compression.

Tests: 14 unit tests for historyMapping (including slash-command and
compression cases), full suite 616/616 passed.

feat(core): detect tool validation retry loops and inject stop directive (#3178)
Primary change: prevent the model from burning tokens in an infinite retry
loop when a tool call repeatedly fails schema validation with the same
error (observed with ask_user_question and a malformed `questions`
parameter retrying 10+ times with the same validation error).

- Track consecutive validation failures per (tool name, error message)
  pair in CoreToolScheduler via a `validationRetryCounts` Map.
- After 3 consecutive failures for the same (tool, error) pair, append a
  RETRY LOOP DETECTED directive to the error response instructing the
  model to stop, re-examine the schema, try a fundamentally different
  approach, or surface the issue to the user.
- Reset per-tool counters when the tool invocation succeeds; reset
  globally when an incoming batch shares no tool name with any
  previously failing tool; reset the per-tool counter when the tool
  returns a different validation error so unrelated mistakes do not
  accumulate toward the threshold.
- Distinct from LoopDetectionService, which tracks model-behavior loops
  (repeated thoughts, stagnant actions); this change catches tool-API
  misuse loops at the scheduler layer.

Piggyback fixes bundled in the same PR:

- packages/cli/index.ts, packages/core/src/services/shellExecutionService.ts:
  treat PTY `EAGAIN` on the read path as an expected read error alongside
  `EIO`, avoiding noisy surface-level failures from transient
  non-blocking reads.
- scripts/build.js: switch the settings-schema generation step from
  `npx tsx` to `node --import tsx/esm` for Bun compatibility.

Tests:

- Unit tests in coreToolScheduler.test.ts cover: directive injection on
  the 3rd consecutive failure, counter reset when a different tool is
  called, and counter reset after a successful invocation of the same
  tool (fail → fail → succeed → fail → fail must not trip the directive).

refactor: merge test-utils package into core (#3200)
* refactor: merge test-utils package into core

Consolidate the standalone @qwen-code/qwen-code-test-utils package
into packages/core/src/test-utils/, eliminating the need for a
separate package that only provided createTmpDir, cleanupTmpDir,
and FileSystemStructure type.

Changes:
- Move file-system-test-helpers.ts into core/src/test-utils/
- Re-export from core's test-utils index
- Update 3 core test files to use relative imports
- Update cli useAtCompletion test to import from @qwen-code/qwen-code-core
- Remove test-utils devDependency from core and cli package.json
- Delete packages/test-utils/ directory

All affected tests pass (fileSearch, crawler, ignore, useAtCompletion).

The previous version (1.1.0) has a native-level bug on macOS where each
PTY spawn leaks one /dev/ptmx file descriptor that is never closed. Over

The bundled skills directory (dist/bundled/) was missing from the published

copy_bundle_assets.js correctly copies bundled skills to dist/bundled/ during
the bundle step, but prepare-package.js omitted 'bundled' from the files
whitelist. This caused SkillManager to find an empty bundled skills directory
at runtime after installation, since npm excluded it during publish.

8161ac4523 fix(hooks): correct JSON schema type for hooks configuration
- Add 'array' type support to SettingItemDefinition
- Change hooks field from object to array type
- Add additionalProperties constraint for env fields
- Fix additionalProperties generation to only apply for object types

This ensures the hooks configuration schema correctly represents hooks as an array
and properly validates environment variable objects.

700806ce83 fix: correct hooks JSON schema type definition
The hooks array items were incorrectly typed as 'string' in the JSON
schema, causing VS Code to show type errors when users configure
HookDefinition objects. This fix adds proper schema support for complex
array item types.

- Add SettingItemDefinition interface for array item schema
- Add items schema for UserPromptSubmit and Stop hooks
- Update generate-settings-schema.ts to convert complex item types

Fixes #2246
