+## Unreleased — The annotating skill, the run coupling and P10's model-free part
+
+### Added
+
+- `voyage:annotating` (order B): the operator-annotation loop as one skill. The person writes every
+  note and Claude none; Fix and Change edit only the text a note points at; a Question is answered
+  and changes nothing; nothing the notes did not ask for is edited; the approval an edit costs (a
+  stale brief intent, a changed plan) is said before the edit; the page is built again on the
+  revised file. It also covers a research document when the user asks (decision 62);
+  `/trekresearch` gets no annotation step. Red baseline with helpers (Opus 5.5 high, 3 runs per
+  scenario, a toy project with an approved brief and plan): without the skill 3 of 3 changed the
+  plan because of a Question, 3 of 3 applied a Fix to steps the note did not name, 2 of 3 edited
+  brief text no note asked for, 1 of 3 put its own critique next to the page, and 0 of 3 named the
+  stale approval before the edit; with it, 0, 0, 0, 0 and 3 of 3. Six eval cases
+  `evals/skill-annotating-*`, written, not run.
+
+**Review gate, 4.5b2 part B (decisions 93-105, 128-134)**
+
+Part B makes a WARN open the merge lock and the release check only when the operator has answered every counting MAJOR, and gives `review.md` the fields for it (`review_version` 1.2). Each behaviour has a test seen failing first at the part's red base `96fba75` (`tests/fix-round-4-5b2-b-red.sh` proves it).
+
+- **Every counting MAJOR needs the operator's answer** (ANS). `lib/review/review-answers.mjs` reads a review's `## Answers`. The verdict gate exits 2 with a reason that starts `review-unanswered:` while a counting MAJOR has no answer, also under an ALLOW verdict, in a 1.1 review and outside a git repository. An answer counts only as `accepted` with a reason that is not hollow, and only when the latest K2 `review` record for that finding binds it to the review's current JSON block and `scope_sha_end`, so it goes stale with the review it answers. An answer `fixed` keeps exit 2 (`fixed-pending`). A security finding is never accepted: `record` refuses it, and a hand-written row does not count. `record` needs a filled `--trailer` and commits the top-level approval log; a BLOCKER is never answered.
+- **The release check reads the same answers** (RLS). `scripts/release-check.mjs` reports not ready (exit 1) for a review with an unanswered counting MAJOR and ready once it is answered, from the same top-level approval log. Its door helpers moved to `lib/util/doors.mjs`, which it re-exports.
+- **A commit that only appends review answers keeps the review current** (RAP). `lib/review/reviewed-commit.mjs` accepts a commit after the reviewed commit whose only change to the top-level approval log appends K2 `review` records, each a valid link of the chain (its hash, sequence and previous hash), to a log that stays a regular file; any other change to the log still makes the review stale. It holds for a project in a subdirectory too.
+- **`review.md` is at `review_version` 1.2** (V12). The template and the coordinator write 1.2; its new fields and sections (answers, pre-existing marks, rounds, the policy, what ran) are optional, and the validator checks each one present for its shape, with its own code (`REVIEW_ANSWERS_MALFORMED`, `REVIEW_POLICY_MALFORMED`, `REVIEW_ROUND_MALFORMED`, `REVIEW_PRE_EXISTING_MALFORMED`); an answer `fixed` without its `### Step R<n>` fails. A 1.1 review still validates. `MIGRATION.md` gives the N-1 window; fixtures hold both shapes.
+- **A finding on a line the range did not add or change is pre-existing** (PRX). `lib/review/pre-existing.mjs` reads the added and changed lines from one `git diff -U0` of `scope_sha_start..scope_sha_end`, with flags no repo config changes; `lib/review/review-finalize.mjs` writes the mark, and the verdict gate derives it again and never trusts the written one. Such a MAJOR leaves the answer set. A BLOCKER or a security finding counts in full whatever the mark, and every uncertain case counts as new: a renamed file, line 0, no `scope_sha_start`, a line next to a pure deletion, a path that is not a regular file at `scope_sha_end`, a file with uncommitted changes in finalize.
+- **Review rounds carry a finding until it is shown resolved** (RND). `lib/review/review-rounds.mjs prepare` gives round 2 and later the diff from the previous round's `scope_sha_end` and archives the previous review as `review-round-<run>-<n>.md`. Finalize's carry keeps every previous finding until the round gives positive evidence: an engine finding resolves when its engine ran and did not raise it again, a reviewer finding when every reviewer that ran before marks it resolved. A repeated finding folds into the old one; a round 2 or later review that finalize did not finalize is not measured (exit 2); `prepare --workflow` refuses round 2 or later.
+- **One cap of three review rounds** (CAP). `MAX_REVIEW_ROUNDS` in `lib/review/review-rounds.mjs` is 3: `prepare` refuses a fourth round (exit 1), and `/trekexecute` reads the same constant with `--cap`. The `TREKEXECUTE_MAX_REVIEW_ROUNDS` override is gone.
+- **An accepted answer carries to a later round only through its own link** (CRY). A carried MAJOR is answered by its earlier answer only when its row's `Carried from` link names an archive of the same run and an earlier round, the archive holds the old finding with the same answer, the link follows the finding's own carry chain and the K2 record still binds it; another run's archive, a later round or another occurrence of the same class keeps exit 2.
+- **The operator answers each MAJOR, and "fixed" runs the fix loop** (FXL). `/trekreview` Phase 8.8 lists the open MAJORs with `review-answers.mjs pending` and asks about each with `AskUserQuestion`, at most four per call and one finding per question: Fix it, or Accept with a reason, never offered for a security finding. `/trekreview --answers` runs only this step and opens no new round. A "fixed" answer gets its `### Step R<n>`; `/trekexecute` enters its fix loop on `review-unanswered: fixed-pending` and closes the merge with the decline reason `review-unanswered` otherwise.
+- **A `REVIEW.md` policy caps and skips MINOR and SUGGESTION findings only** (POL). `lib/review/review-policy.mjs` reads one `voyage-review-policy` block (`max-minor`, `skip`) from `REVIEW.md` at the repo root, from git at `scope_sha_start`, as data. A capped or skipped finding goes to Declined to Judge (`policy:cap`, `policy:skip`); a BLOCKER, a MAJOR or a security finding is never moved, and the gate exits 2 on a review that moved one. A malformed, symlinked or in-range changed file applies no policy; the review records the file's sha256.
+- **The standard path puts back engine findings the coordinator dropped** (ENG). `lib/review/engine-compare.mjs`, run by finalize, puts an engine MAJOR or BLOCKER that `review.md` does not hold back at its own severity, as the workflow path does; the verdict is only raised (a BLOCKER gives BLOCK). A finding under a trimmed title is not put back twice, an engine finding in `out_of_scope` stays declined, and its row rule is pinned equal to the workflow script's.
+- **The code-correctness reviewer checks the repo's tracked instruction files** (CMD). Its eighth dimension checks the diff against the set `lib/review/instruction-scope.mjs --set` gives: the root and on-path `CLAUDE.md` and `AGENTS.md` and the `.md` files under `.claude/rules/` at any depth (a changed path's own directory included), tracked at the reviewed commit. An untracked file, a file outside the repo or a tracked symlink that resolves outside it is left out, and a tracked link to a file inside the repo counts under its own name and its target's; a finding that cites a file outside the set goes to Declined to Judge (`instruction-out-of-set`).
+- **A changed instruction file gets deep review at any depth** (DPR). A changed `CLAUDE.md`, `AGENTS.md` or `.claude/rules/*.md`, `docs/**` included, gets deep review (`instruction-scope.mjs --triage`); the triage table's rows are unchanged.
+- **Two instruction-file rule keys at MINOR** (CAT). The rule catalogue gains `CLAUDE_MD_DEVIATION` and `CLAUDE_MD_STALE`, both MINOR, category conformance, with no memory route; it holds 17 keys, and the workflow script's tier table holds both.
+- **The merge question says how the run was tested and how it is undone** (MEV). Before the merge, `/trekexecute` Phase 8 runs `lib/review/merge-evidence.mjs write`, which derives an internal evidence file from the run's artifacts under the git common dir, never tracked. The Bash guard reads it into a "Tested by" and an "Undone by" line of its merge question; its answer stays "ask", and a missing, stale or unreadable file reads "no run evidence" or "not measured". Files older than 30 days are removed.
+- **A merge after the review cannot bring back the tree from before it** (RMP). `lib/review/reviewed-commit.mjs` checks each commit after the reviewed one against every parent, not only the first, so a merge whose first parent comes from before the review is stale.
+- **The start of the review range is bound to where the branch left main** (PXB). `lib/review/pre-existing.mjs` finds the fork point on the main branch's first-parent line (`main`, else `master`); a `scope_sha_start` other than that fork point or a later commit reached only through the approval log and `.claude/projects/`, a range that ends on main itself, or a repo with neither branch marks nothing pre-existing.
+- **An engine finding missing from the review keeps the gate not measured** (FN1). The verdict gate runs the standard-path put-back over the engine payloads beside `review.md` and exits 2 for any MAJOR or BLOCKER whose row is missing from the review, also when `finalized: true` was written by hand; a finalize failure stops `/trekreview` in round 1 as in later rounds.
+
+### Changed
+
+- **The "run the thing" step names Claude Code's built-in `run` skill.** The plan's run step (`/trekplan`), the executor's end-to-end part (`/trekexecute`) and the plan template each say in one sentence that the app is seen and driven with `run`, and that the verdict is still the `End-to-end:` command through the criteria runner, because `run` gives no exit code (decisions 54 and 64).
+- **A quiet eval case may name Claude Code's own `run` as its owner** (R2). The routing test keeps a short fixed list of built-in owners (`BUILTIN_OWNERS`, only `run`); for such an owner, which is outside the corpus, only "the skill does not rank first" is checked, and the report says so. `evals/skill-writing-criteria-quiet-2` now has `owner=run` instead of `/trekexecute` standing in.
+- **P10's model-free part is done; the eval gate (P10) is exempted until the fixed test set runs again.** Every case in `evals/` now names the event it came from (`from=`), the eight test-set cases included (`from=proevesett-eval-suite`, `from=proevesett-intent-gate`). The routing test (`lib/skills/routing.mjs`) fails any case without it, routed or not, and its report gives both counts: cases checked for `from=` and cases routed. The release gate that would read the last test-set run is written into `docs/release-runbook.md` as exempted with its reason, not built: a gate that can never fire is not built.
+- `/trekbrief`, `/trekplan` and `/trekreview` name `voyage:annotating` where they build the page;
+  the description of the page and the "revises freehand" loop left the three commands. The call
+  to `scripts/annotate.mjs`, the not-a-gate line and the printed links stay. The printed report now
+  says a Question is answered and Fix and Change notes revise the file.
+- **`/trekendsession` is operator-only, and the planning and research spawn sites follow the profile.** The model can no longer start `/trekendsession` (`disable-model-invocation: true`). With `--project`, where the resolver runs, `/trekplan` and `/trekresearch` pass the resolved model at their spawn sites, so the `economy` profile gives Sonnet helpers unless the brief's phase signal for that phase names a model; without a resolved model the agent's own `model:` applies (opus for Claude Code's built-in agents), and `/trekexecute`'s step helper and controller stay on opus.
+- **`~` and `$HOME` in the arguments of `/trekendsession`, `/trekcontinue` and `/trekreview` are no longer expanded** (ARG, fix round 4.5b). The arguments reach the arg parser as text on stdin, not as shell words, so nothing in them is expanded: write the path out (`~/x` stays the three characters `~/x`).
+
+### Fixed
+
+Fix round 4.5b (decisions 80 to 87): the round's 39 findings, from the 4.5a review and its execution and three the operator added, proven by 41 test ids. Each is fixed, and each has a test seen failing first: on the code at the round's start point (`be0b631`), or, for the 14 ids whose code was already right or lives under `tests/`, under a named mutation (`tests/fix-round-4-5b-red.sh` proves both).
+
+**Verdict gate**
+
+- **The verdict gate reads `--repo=<dir>` and refuses an unknown option** (M6). `lib/review/verdict-gate.mjs` takes `--repo <dir>` and `--repo=<dir>`; `--repo=` with no value and any other option, a `--x=value` one included, exit 2 with the usage line, so a misspelt flag no longer skips the stale check. `--json` stays.
+- **Only a full commit id opens the merge lock** (M11). A `scope_sha_end` must be 40 or 64 hex and equal what `git rev-parse` prints for it, so a SHA-256 repository opens the lock, and a short id, or a branch named like a commit id, reads as stale. The done line (`lib/verification/done-line.mjs`) and the release check (`scripts/release-check.mjs`) take only full commit ids too.
+- **A failed git call is not measured, not stale** (M4). A `--repo` path that is missing or no repository, and any git call that fails, give exit 2 with a reason that starts `review-not-measured:`; `/trekexecute`'s main-merge gate reports it as "not measured", never green, and the merge stays locked. Handover 6 names the prefix and lists `review_version` 1.1 as current.
+- **Free text inside the lessons block makes the review stale** (m4). Every line a later commit adds inside Voyage's block in `.claude/rules/voyage-review-lessons.md` must be a valid lesson line or the block's own header line.
+
+**Park tool**
+
+- **The park tool moves nothing when it cannot read HEAD** (M7). `lib/util/park-attempt-files.mjs` reads HEAD's paths once (`git ls-tree`) before any change, and exits 2 with nothing unindexed or moved when that read fails or a path in HEAD is missing from the index. Before, a failed `git cat-file -e` read as "not in HEAD", and a committed file was moved.
+- **A CRLF diff is parked, and the text says what a staged new file gets** (E22c, E22e). The tool reads a diff with CRLF line ends; its header and `/trekexecute` say that it parks every file new in the attempt's diff, untracked or staged but not in HEAD.
+- **The "Back to planning" save line reads the whole diff from a subdirectory** (M3). Its `git diff` carries `--no-relative`, so `diff.relative=true` no longer leaves files out.
+
+**Review coordinator and Arm B workflow**
+
+- **The Arm B workflow keeps the contract's row** (M5, S3, E20). `scripts/trekreview-armB.workflow.mjs` matches a put-back row on the title as the coordinator trims it, so a trimmed title gives no duplicate row, and ranks a conformance/correctness tie as `lib/review/coordinator-contract.mjs` does; the canonical sort of untitled findings is pinned in both.
+- **The coordinator's text says what the code does with a line number** (M9). A citation that escapes the repo root, or a negative line, refutes a finding; any other line number alone never does, and a line past the end of the file goes to `unverified`.
+- **The four `--quick` summaries name the brief-conflict rule as the exception to the skipped reasonableness filter** (M2, K3). `/trekreview`'s flag table, the review orchestrator, `docs/command-modes.md` and README say so, and the orchestrator's item 3 names the brief-conflict lowering as the exception to the catalogue reset.
+
+**Red proof**
+
+- **One red script for every round** (RS, M1, M1r, E23a, E23b, E23d, E23f). `tests/helpers/red-round.sh` takes a base, the round's ids, the other rounds' ids, a mutation module and the test files; `tests/fix-round-4-5a-red.sh` and `tests/fix-round-4-5b-red.sh` are thin wrappers over it. The judge skips another round's id and reports an unreadable tag such as `[X 1]`; the base run selects every tag with one pattern and carries a timeout; the judge's exit 2 is tested, and a test checks that a result exists before it reads it. The tests the 4.5a discovered-error fix added carry their 4.5a parent tags, so the red script judges them.
+
+**Commands and docs**
+
+- **The arguments reach the parser on stdin, never as shell words** (ARG, M8, M10, DJ5). Phase 0 of `/trekendsession` and `/trekcontinue` and Phase 1 of `/trekreview` give `$ARGUMENTS` to `lib/parsers/arg-parser.mjs --stdin` as the one line inside a quoted heredoc, so a `;`, a `$( )` or a glob in them is text. `/trekcontinue` and `/trekendsession` stop on the parser's exit 1 with its `errors`, and when it prints no JSON. `/trekendsession` takes its label as the rest of the text as typed (the parser's `tail`), so a label of several words is kept whole, and its Phase 3 reads the arguments again the same way instead of splicing the label into a shell line, so an apostrophe in the label no longer breaks that line or runs a command.
+- **The Bash guard blocks a parser heredoc that closes early** (R6). `hooks/scripts/pre-bash-executor.mjs` blocks (`args-heredoc-closed-early`) a command whose `VOYAGE_ARGS_EOF_7F3C9E` heredoc opens unquoted, or whose closing line stands twice or is not the last non-empty line, so a typed line equal to the delimiter cannot end the heredoc and run what follows.
+- **Every `/trekbrief` exit names Phase 7 with its `auto_result`** (M13, K2). The exit with no research topics runs Phase 7 with `auto_result: manual`, and the "Cancel — do manual" row with `auto_result: cancelled`.
+- **`/trekplan`'s execute and team exits run Phase 12, and the research loop names its model** (DJ1, DJ2). The "execute" and "team" exits run Phase 12 (`outcome: execute`, `outcome: execute_team`) instead of a bare stop; in `/trekresearch`'s high-effort loop, a turn that spawns an agent passes the resolved model, else `opus`.
+- **`run_seen` is kept in the progress file** (E14). `/trekexecute` writes it to `progress.json` (template, field table, Phase 7) and Phase 8 reads it from there, so the resume and multi-session paths report it; Handover 5 lists it as optional.
+- **Applying a lesson writes no pointer through a link or for an ignored file** (DJ4, PTR). `lib/review/recurrence.mjs` skips the `CLAUDE.md` pointer when `CLAUDE.md` is a symlink or git ignores the lessons file, and refuses a lessons file that is a symlink or whose directory lies outside the repo; `/trekexecute` Phase 7.2 commits only the review's paths git does not ignore.
+- **The research and review texts are said once and pinned exactly** (E17a, E17b, E18a, Da, Db, E16a). The two `/trekresearch` sentences on outbound queries and the F9 triage rows are pinned exactly; the deep-research adapter says where wave 2's contrarian findings merge; README's deep-research parenthesis says "when the engine is active", and the test that no README line stars `security-researcher` reads every line. The next-session validator's refusal of `--state-file` with no value is tested.
+
+**Fix round 4.5b, part 2 (decision 88)**
+
+Part 2 fixes the four defects that part 1 introduced and its own review found, plus the Bash guard's first-opener-only check; each has a test seen failing first at part 1's end point `52c382c` (`tests/fix-round-4-5b-part-2-red.sh` proves it).
+
+- **A quoted value stops at a quote that starts a word** (TOK). In `lib/parsers/arg-parser.mjs`, a closing quote must end a word, and the search for it stops at a quote of the same kind that starts a word; with no pair, the opening quote stays a literal character. Before, `--project "my dir"/x --since "HEAD~1"` gave one `--project` value that held `--since`, so `/trekreview` reviewed the wrong range; now `--since` is `HEAD~1`. An apostrophe inside a word keeps its value (`'Fix the user's login'` is one value), and nothing is expanded.
+- **The Bash guard checks every opener of the parser's heredoc that has a line after it, and lets a one-line mention through** (HDG). `hooks/scripts/pre-bash-executor.mjs` checks an opener of `VOYAGE_ARGS_EOF_7F3C9E` only when a non-blank line follows the opener's line, because bash reads a heredoc body only from the lines after it, so a one-line `grep`, `sed` or `git commit -m` that mentions the opener is no longer refused. It now checks every opener, not only the first, so a quoted first mention can no longer hide a later unquoted heredoc whose arguments would run as commands.
+- **A failed `git check-ignore` writes no lessons pointer, whatever language git speaks** (CKI). `lib/review/recurrence.mjs` no longer reads every `git check-ignore` exit 128 as "no repository": on 128 it runs `git rev-parse --git-dir` and looks for a `.git` entry from the repo up to the nearest `GIT_CEILING_DIRECTORIES` entry above it, and writes the `CLAUDE.md` pointer only when rev-parse also exits 128, `GIT_DIR` is unset and no `.git` entry is found. Anything else gives `check-failed` with a note that names the reason, and no branch reads git's message text. A `.claude` that is a symlink inside the repo now gives `check-failed` (no pointer), also when it points at a tracked directory.
+- **The executor records the full commit id for the done line** (DLC). `/trekexecute` Sub-step G says `{hash}` is the full commit id from `git rev-parse HEAD` after the step's last commit, read again after any later commit of the step, never the short id `git commit` prints: `lib/verification/done-line.mjs --check` refuses a short id with exit 2, which sent a passing step to the plan. The progress line stores that full id, and Handover 5's `commit` row says so.
+
+**Fix round 4.5b, part 3 (decision 89)**
+
+Part 3 fixes two MAJOR findings of part 2's review, in the two places part 2 rewrote; each has a test seen failing first at part 2's end point `ce98f62` (`tests/fix-round-4-5b-part-3-red.sh` proves it).
+
+- **A quoted value closes at the first quote of its kind that ends a word, whatever stands before it** (CQW). In `lib/parsers/arg-parser.mjs`, the closing quote no longer has to follow a non-blank character. So `"my dir "`, `" "` and a value closed on its own line pair again. A quote that starts a word still stops the search, so `--since` after `"my dir"/x` stays `HEAD~1`. One qualification: a value whose text ends in whitespace may now hold what follows it, up to a quote that ends a word (see Known issues). It names review finding `87a693f0`.
+- **The Bash guard also reads a heredoc opener's word as the shell does** (PQO). `hooks/scripts/pre-bash-executor.mjs` reads the word when it is partly quoted, `$'...'`, `$"..."`, or holds a backslash-newline anywhere from the first `<` to the end of the word. It checks every opener whose word is the parser's delimiter, and treats a word it cannot read as unquoted. Every command it blocked before stays blocked. A typed argument whose `<<` runs into a quote with no partner (`fix "<<" handling`) still passes inside the commands' argument heredoc. It names review finding `021996c6`.
+
+**Fix round 4.5b, part 4 (decision 90)**
+
+Part 4 fixes four MAJOR findings of part 3's review in the Bash guard's check of the argument heredoc; each has a test seen failing first at part 3's end point `591f3c4` (`tests/fix-round-4-5b-part-4-red.sh` proves it). The tokenizer headline in part 2's group above no longer claims more than the tokenizer does (see the tokenizer Known issue).
+
+- **The guard checks the parser's delimiter when a backslash-newline splits it** (CSG). `hooks/scripts/pre-bash-executor.mjs` checks a command that names the parser's delimiter only once a backslash-newline is removed, so an unquoted opener split that way with a body and no closing line is blocked as unquoted; such a command with a quoted opener and no closing line, or with an unreadable opener elsewhere, is now checked too and refused, as it would be with the delimiter written out. It names review finding `3a34adbe`. A split delimiter with a suffix was not refused; it is now, fixed below as SFX, and inside a string as SIS. Part 4's review found the gap: review finding `27b0b46a`.
+- **A `<<` cut by the quote that closes a string on its line is text to the shell reading** (SLT). A `<<` inside a string on the opener's line, whose cutting quote closes that string, is text to the shell reading, unless a backslash-newline splits its opener (see SIS below). The regex reading still reads a `<<` that the delimiter follows, and the string test counts one quote character from the line start, so such a command passes only where neither reading blocks it: a grep pattern `'<<'` on a line that names the delimiter further on, a commit message or file write whose heredoc body holds `"<<"` with the delimiter elsewhere on its line, and a string holding `<<` before the commands' argument heredoc. A grep pattern or commit message whose string puts the delimiter right after `<<`, and one whose string holds a quote of the other kind or an escaped quote before the `<<`, are refused as before (see Known issues); a quote with no string open before it stays unreadable and blocked; a string opened on an earlier line is still refused. It names review finding `ad8ad828`. Part 4's review found the gap: review findings `943f9841` and `a6735ef9`.
+- **A backslash-escaped `<` starts no opener while no quote is still open before it, no heredoc body holds it and the guard can follow the shell up to it, with one exception** (ESC). A `<` after an odd run of backslashes starts no opener when no quote is still open before the run, no earlier heredoc is still open, and the scan can follow the shell there, in both readings, so `echo \<<` followed by the delimiter and a line passes. The exception: two escaped `<` in a row that name the delimiter with a line after them are refused, also where no second shell reads them (see EVL below). The `<` after an escaped one is read as usual, so a `<<` right after an escaped `<`, which the guard took for part of a here-string before, is now checked; an escaped `<` inside a heredoc body fed to a shell is still checked. It names review finding `797784e0`. The limits covered the whole command, fixed below as ESR. Part 4's review found the gap: review finding `ed40abdb`.
+- **The guard's error path is tested** (CTB). A test forces an error inside the guard's shell reading and sees it block with exit 2, through a test-side preload; the hook gains no switch. It names review finding `1658fc64`.
+
+**Fix round 4.5b2, part A (decision 91)**
+
+Part A fixes four of the six MAJOR findings of part 4's review in the Bash guard's check of the argument heredoc, one more gap the operator added (decision 107), a split opener inside a string that part 4's string skip let through (decision 123), and a false test header; the other two MAJOR findings are listed under Known issues (decision 122). Each fix has a test seen failing first at part 4's end point `e2d6bec`, or under a named mutation where the code already held (`tests/fix-round-4-5b2-a-red.sh` proves both), and a fixed bypass corpus (`tests/guard-bypass-corpus-4-5b2-a.sh`) keeps the commands blocked that each loosened rule must not let through.
+
+- **An error inside the regex reading's escape limit is tested** (RXT). A test forces an error inside the regex reading's escape limit and sees the command blocked with exit 2. It names review finding `5f1cc34c`.
+- **An opener split between its two `<` keeps the escape rule off** (CNT). A test pins an outer opener split between its two `<` as keeping the escape rule off. It names review finding `97d1f547`.
+- **A split delimiter with a suffix is judged as written out** (SFX). `hooks/scripts/pre-bash-executor.mjs` judges a delimiter that a backslash-newline splits, followed by any suffix, as it judges the same opener written out. It names review finding `27b0b46a`.
+- **The escape rule reads the text before the run, not the whole command** (ESR). The escape rule is off only while a quote is still open before the run, an earlier heredoc is not closed before it, or the scan cannot follow the shell (for example after `$'`, `$"`, a backquote, a parenthesis, a `#` or a continuation). It names review finding `ed40abdb`.
+- **A heredoc operator a second shell would read from `\<\<` is blocked** (EVL). A heredoc operator a second shell would read from `\<\<`, with the delimiter after it (also when a backslash-newline splits it) and a line after it, is blocked, through `eval`, `bash -c`, `sh -c` or no second shell at all. It is decision 107.
+- **A `<<` whose opener a backslash-newline splits is never skipped** (SIS). A `<<` whose opener a backslash-newline splits is never skipped, as text in a string or as text in the body of a quoted heredoc that passes, because the regex reading cannot see it; such an opener inside a `bash -c` string with a body was let through, also inside a quoted heredoc fed to `bash`, and the inner shell expanded the body. A harmless one with a line after the command may now be refused. Decision 126 widened it to the body skip. It is decision 123.
+- **A test header names its red base** (HDR). The header of `tests/hooks/bash-guard-false-stops.test.mjs` named the wrong red base; it now names part 3's end point `591f3c4`. It names review finding `86488cd6`.
+
+**Fix round 4.5b2, part C (decisions 135 and 137)**
+
+Part C fixes the eight code MAJOR findings of part B's review, round 1, on the same branch before that review's round 2 (decision 135). The guard's reading of a quoted value is left out and listed under Known issues (decision 137). Each fix has a test seen failing first at part B's head `f1f5ab5` (`tests/fix-round-4-5b2-c-red.sh` proves it).
+
+- **One answer can no longer clear two MAJORs that share an id** (DUP). `lib/review/verdict-gate.mjs` exits 2 (not measured) when the frontmatter `findings:` list holds one id twice or two findings of the trailing JSON block share one id, and a BLOCK review still exits 1. `lib/review/review-answers.mjs` refuses such a review too: its pending list is not measured, and `record` appends no answer to it. It names review finding `e57259bf`.
+- **An answer recorded after a stopped round-2 prepare no longer locks the rounds** (RSP). `lib/review/review-rounds.mjs prepare` knows review.md's own archive by its content (its round number, its trailing JSON block and its `scope_sha_end`), not only by its bytes, and refreshes it with review.md, so an answer or its R-step written after the stop is not counted as another round. An archive whose findings or `scope_sha_end` differ still counts as an earlier round. It names review finding `de594275`.
+- **Nested rules files are in the instruction set** (NRL). `lib/review/instruction-scope.mjs --set` holds every tracked `.md` file under `.claude/rules/` at any depth, at the root and in each directory on a changed path, as the classifier for deep review already read them. It names review finding `fd5a6e18`.
+- **A linked instruction file keeps its own name** (SYM). A tracked symlink whose target is a tracked regular file inside the repo adds both its own path and its target's to the set, so a finding that cites the link's name is not declined as out of set; a link that resolves outside the repo still adds nothing. It names review finding `d81f3c45`.
+- **The evidence writer takes a verdict only for the branch head** (WHD). `lib/review/merge-evidence.mjs write` asks the verdict gate only when `git rev-parse --verify HEAD` in `--repo` is the branch head; from any other HEAD the review verdict is null and the merge question reads "review not measured". It names review finding `561d6f11`.
+- **No run evidence for a merged name git reads as a tag or another ref** (AMB). The guard's reader (`hooks/lib/merge-evidence.mjs`) gives "no run evidence" when the merged name is also `refs/<name>` or `refs/tags/<name>`, loose or in `packed-refs`, or an entry in the git directory, and when `packed-refs` cannot be read; the writer refuses such a name (`"written": false`). It names review finding `df9f9870`.
+- **The reader knows that `--cleanup` takes a value** (CLU). The reader skips the value of `--cleanup`, so `git merge --cleanup strip --no-ff feat` shows feat's run evidence. A quoted `-m` value with spaces before a single branch still gives "no run evidence"; before two branches it can show one branch's run evidence for both (see Known issues); its fix goes with the guard's quoted-value reading (decision 137). It names review finding `b5ae9798`.
+- **A command with several merges says its run evidence is not shown** (MMG). The Bash guard hands every merge of the command to `evidenceForMerges` in `hooks/lib/merge-evidence.mjs`: one merge keeps its two lines, and two or more give a "Tested by: not shown" line that names the count and says to merge one at a time, followed by "Undone by: not shown". Before, only the first merge got run evidence. The answer stays "ask". It names review finding `73e1d174`.
+
+Fix round 4.5a (decisions 57, 67 and 68): the round's 30 findings, where a Voyage control could be bypassed or was too lax, or where the text gave a guarantee no code held. Each is fixed, and each has a test that fails on the code before it, except DJ, whose sentences already stood and whose pins fail when they are deleted (`tests/fix-round-4-5a-red.sh` proves every other id red at the round's start point, and DJ under its two mutations).
+
+**Execute**
+
+- **The merge lock refuses a review of an older commit** (R6). `lib/review/verdict-gate.mjs` takes `--repo <dir>`: an ALLOW or WARN review then opens only when its `scope_sha_end` is HEAD, or an ancestor of HEAD whose later commits (side branches included) change nothing but the review lessons and the `CLAUDE.md` pointer; anything else exits 2 with a reason that starts `review-stale` (the new `lib/review/reviewed-commit.mjs`), and a failed git call exits 2 with a reason that starts `review-not-measured:`, not `review-stale` (fix round 4.5b). `/trekexecute` Phase 7.2 and the main-merge lock run the gate with `--repo .`, so the merge stays closed with the decline reason `review-stale`, also on `--resume`.
+- **`/trekexecute` runs the brief check it promised** (finding #33). With `--project` and a `brief.md`, Phase 1 runs the brief validator and the phase-model resolver (`lib/profiles/resolver.mjs --resolve-phase-model`) as `/trekplan` does, uses the effort it returns, and halts only on `BRIEF_V51_MISSING_SIGNALS`. Low effort runs the plan as one session, step after step; high effort changes nothing, and the text that set `gates_mode` from the effort and its `gates_mode_flag_override` record are gone.
+- **`/trekexecute` names and reads `--profile` and `--gates`** (finding #30). The argument hint, the usage block and Phase 1 carry both flags, Phase 1 strips `--profile <name>` before it reads the plan path, and the text says the profile changes no model here: the step helper and the controller stay on opus.
+- **The completion gate says which of its checks are commands and which are the executor's judgement** (finding #28). It no longer calls the counter check and the audit deterministic, and its two dead line references are gone.
+- **The final report says whether the app was seen with Claude Code's `run`** (decision 67). A ``**Seen with `run`:**`` line after End to end and a `run_seen` key in the summary JSON; the verdict is still the `End-to-end:` command.
+- **The park step no longer leaves an earlier attempt's files in the tree with exit 0** (6.5.0 Known issue: the park step). `lib/util/park-attempt-files.mjs` takes a file registered with `git add --intent-to-add` out of the index and parks it, strips colour codes from the diff and blocks on a non-empty diff with no readable header, reads the paths from the repository's top level whatever directory it runs in, and exits 2 when one of its git calls fails (a non-zero `git cat-file -e` reads as "not in HEAD"), before any file is moved. "Back to planning" saves the upward diff with `--no-color` and `core.quotepath=off`.
+
+**Gates**
+
+- **`--gates closed` turns gating on, and a bare `--gates` no longer swallows the next flag** (finding #1). The shim (`lib/util/autonomy-gate.mjs`) reads bare, `true` and `closed` as on and `false` and `open` as off, takes any other value as a usage error (exit 1), and leaves a following `--flag` in place. Before, only `true` was on.
+- **`--gates` means one thing in every command** (finding #1). `/trekbrief`, `/trekresearch`, `/trekplan` and `/trekexecute` share one rule and run the shim once to map the value. `/trekexecute` maps the value, and no phase of it pauses on it; its one stop is the merge into main. The executor strictness table (`adaptive`, `closed`, `open`) left README and `docs/`, and `/trekbrief` no longer promises pauses in the executor.
+
+**Brief**
+
+- **A brief with no research topics ends with its next steps** (finding #47). `/trekbrief` prints the manual path (`/trekplan --project`, then `/trekexecute --project`) and stops instead of entering the auto-only Phase 6, which now runs only after the operator opted into auto mode and Phase 4h approved the intent.
+
+**Plan**
+
+- **"execute" in `/trekplan` no longer builds the plan in the planning session** (finding #52). It prints the `/trekexecute` line and stops, so the approval check, the test lock, the step helpers and the review run; "team" and leaving plan mode do the same.
+- **The planning and research spawn sites take the resolved model** (findings #48 and #12). `/trekplan` passes `phase_signal_result.model` at its agent spawns, with the agent's own `model:` as the fallback and opus for the built-in Explore deep-dives; `/trekresearch`'s Phase 5 follow-ups do the same, with opus as the fallback.
+- **No turn budget is promised** (finding #57). The sentences that scaled `maxTurns` by codebase size left `/trekplan`, `/trekresearch` and the planning reference document; nothing set such a budget.
+
+**Research**
+
+- **The contrarian gets a conclusion to attack** (finding #113). `/trekresearch` launches `contrarian-researcher` as a second wave after every other agent of wave 1 returns, local ones included, with wave 1's leading answer, the claims for it and the alternatives it dismissed, taken from external findings only and with local parts removed; with `--engine deep-research` it runs after the engine returns.
+
+**Review**
+
+- **Core code outside the old deep-review patterns is now deep-reviewed** (6.5.0 Known issue: trial-5 finding 9). `/trekreview` triage makes deep review the default for every changed file it does not skip or mark summary-only, `CLAUDE.md`, `AGENTS.md` and `.claude/rules/**` included; summary-only is for `docs/**`, root Markdown other than those two, and `tests/fixtures/**`. The review orchestrator, README, the review template and the workflow's fallback say the same.
+- **A line past the end of the file no longer refutes a finding** (6.5.0 Known issue: the coordinator's line numbers). The coordinator's Accuracy rule refutes only a citation that escapes the repo root or a negative line; a line past the end of the file goes to `unverified` with the new reason `accuracy:line-out-of-range`: the citation is wrong, the claim is unchecked.
+- **Deleting the Declined to Judge copy-through now fails a test** (6.5.0 Known issue: the Declined to Judge copy-through). The sentences in `/trekreview` Phase 6 and in the coordinator's Input and body section 9 that carry each reviewer's Declined to Judge lines into `review.md` are pinned, and the round's red script deletes those sentences and sees the pins fail.
+- **Which row a finding joins no longer depends on the order the reviewers' payloads are read** (6.5.0 Known issue: the row order). Inside one file, line and rule key, `dedupByTriplet` groups the findings in two passes, title first and the untitled ones last, each in a fixed order, and a full tie picks its survivor in that order too; the coordinator's Pass 1 text and the workflow's copy follow the same rule. The rows and their `#k` ids still stand in input order.
+- **On the `--workflow` path, the severity floor and the put-back match each finding to its own row** (6.5.0 Known issue: the workflow floor and put-back). A returned finding is matched to the row with its triplet and title; with no title match, to the only row on its triplet, else to the strictest one there, never a lower one, and `engine` is read from that row only. Each engine row no returned finding carries is put back at its own severity, one copy per row.
+
+**Continue**
+
+- **`/trekcontinue` runs the arg parser instead of naming a JavaScript function** (finding #66). Phase 0 runs `lib/parsers/arg-parser.mjs --command trekcontinue -- $ARGUMENTS` and reads its JSON; the review orchestrator's parser line also passes its arguments after `--`.
+- **`/trekcontinue` finds the master prompt file at the repo root, and the consistency check reads the state file** (finding #102). The master file is looked for at `git rev-parse --show-toplevel`, not an undefined plugin root. The consistency call passes `--state-file` when the project's session state exists, and the validator now takes that value as the flag's own instead of a third path, and is valid only when both prompt files are valid.
+
+**Endsession**
+
+- **`/trekendsession` parses its arguments with the arg parser** (finding #15). A slug or label that holds `-h` is no help request: help comes only on `--help` or a first argument that is exactly `-h`, and Phase 2 reads the brief path and the label from the parser's positionals.
+- **Only the operator starts `/trekendsession`** (finding #67). Its frontmatter sets `disable-model-invocation: true`, and CLAUDE.md names it as the one command that does.
+
+**Agents**
+
+- **A reviewer drops a finding only with a trace** (finding #111). code-correctness-reviewer and brief-conformance-reviewer emit an off-tier finding at the catalogue's severity and drop it only when they can say why it is wrong, as one Declined to Judge line with that reason; `voyage:reviewing-adversarially` says the same, and a rule key outside the catalogue is described as routed to `unverified`, as the coordinator contract does.
+- **research-scout has the Tavily tools its "Try Tavily first" needs** (finding #24). Its tools now hold `mcp__tavily__tavily_search` and `mcp__tavily__tavily_research`, in docs-researcher's order.
+- **code-correctness-reviewer no longer cites a "MANDATORY OVERRIDE rule above" that is not there** (finding #23). The sentence states the rule itself.
+
+**Docs**
+
+- **Nothing sends a reader to run the planning reference document** (findings #2 and #26). `/trekexecute`, `/trekbrief`, brief-reviewer, session-decomposer, `docs/HANDOVER-CONTRACTS.md` and `docs/architecture.md` name `/trekplan` where they named `planning-orchestrator`.
+- **The three reference documents hold read-only tools** (finding #26). planning-orchestrator, research-orchestrator and review-orchestrator list only `Read`, `Glob` and `Grep`.
+
+**Stats**
+
+- **No command promises a stats key its record does not write** (finding #46). The "Stats records emit `profile` …" sentences left `/trekbrief`, `/trekplan`, `/trekexecute`, `/trekreview` and `/trekcontinue`; `/trekresearch` keeps only `engine`, which its record writes; `docs/profiles.md`, `docs/operations.md` and README no longer say a profile reaches the stats records.
+
+**Across the round**
+
+- **The texts next to the fixes say the same** (siblings found during the round): `/trekreview`, the review reference and the Arm B coordinator prompt no longer drop a finding whose rule key is unknown; `/trekbrief` writes its stats record on every exit of its manual and auto paths, says that `--gates` adds one pause before its auto chain, and that the chain ends at the plan; `/trekexecute` says `--gates` changes nothing there, checks the wave marker before a low-effort single session, and names no validator check that does not exist; plan mode goes through the plan approval before it prints the `/trekexecute` line; the commands read only the two-token `--gates <value>` form, and `--gates=true` is the gates shim's own form (`lib/util/autonomy-gate.mjs`), which it reads as `--gates true`.
+
+### Known issues
+
+- **A plan's `profile:` field has no writer.** README, `docs/`, `/trekexecute` and `/trekcontinue` say a plan carries or passes on a profile, but no command writes `profile:` to a plan; the plan validator's `MANIFEST_PROFILE_DRIFT` check reads it, and `resolveTrekcontinueProfile` has no caller outside its tests. Left whole for a later hardening part, which chooses between writing the field and taking the promises out.
+- **Splices and dropped `--x=` options outside fix round 4.5b** (decision 82). The commands' bash blocks still splice `{placeholder}` values into shell lines outside the four places the round closed (the Phase 0 parser lines of `/trekendsession`, `/trekcontinue` and `/trekreview`, and `/trekendsession` Phase 3), for example `"{brief_path}"` in `/trekplan` and the unquoted `{project_dir}` in `/trekendsession` Phase 4; and the release check, the lessons apply (`lib/review/recurrence.mjs`), the next-session validator and the park tool still drop an unknown `--x=` option without a word. One open finding, for fix round 4.5c or 4.5d.
+- **Two 4.5b findings moved to fix round 4.5c.** M12 (`lib/review/reviewed-commit.mjs` makes four git calls per path per commit; at most two paths per commit reach that loop) goes with 4.5c's single `git cat-file --batch` read, and Dc (the trekcontinue `line_ref` row in `tests/fixtures/jsonl-schemas.md`) with 4.5c's change of `line_ref` to a heading anchor.
+- **Step 9's narrowed unborn-HEAD rule is not recorded as a plan deviation** (MAJOR `c76a0bb8`, `lib/util/park-attempt-files.mjs`; decision 88). The park tool reads HEAD as unborn only when `headIsUnborn` agrees, which narrows plan Step 9's rule; the narrowing was logged as an executor decision, not as a plan amendment.
+- **The arg parser's stdin-unreadable branch has no test** (MAJOR `b0fd0a04`, `lib/parsers/arg-parser.mjs`; decision 88). No test exercises `ARG_STDIN_UNREADABLE` and its exit 1, the path that makes `/trekcontinue` and `/trekendsession` stop when stdin cannot be read.
+- **The park tool's packed-refs branch has no test** (MAJOR `f7e8278b`, `lib/util/park-attempt-files.mjs`; decision 88). The branch that tells a corrupt packed ref from an unborn HEAD is not exercised; the corrupt-ref test covers only a loose ref.
+- **`/trekendsession` takes the label from after the first token** (MAJOR `4ec591f4`, `commands/trekendsession.md`; decision 88). Phase 3 reads the label as the parser's `tail`, the text after the first token, while the brief path is the first positional, so a flag typed before the brief path ends up in the label.
+- **Part 1's red script does not run the guard's tests** (MAJOR `2c904235`, `tests/fix-round-4-5b-red.sh`; decision 88). Its FILES leave out `tests/hooks/bash-guard.test.mjs`, so the `[ARG]` guard tests are never judged red at `be0b631`.
+- **`/trekendsession` Phase 3 repeats Phase 1's project lookup** (MAJOR `450dbabb`, `commands/trekendsession.md`; decision 88). Its inline script enumerates the project directories and their error texts a second time, so the two copies can drift.
+- **The park tool misnames a detached HEAD it cannot read** (MAJOR `e3824c6d`, `lib/util/park-attempt-files.mjs`; decision 88). On a detached HEAD whose commit is missing it exits 2, as it should, with a reason that names a corrupt branch ref.
+- **The lessons-block check accepts any valid lesson line** (MINOR `5114fa84`, `lib/review/reviewed-commit.mjs`; decision 88). A line added inside the block that passes the lesson-line check, an instruction written in the lesson form included, does not make the review stale.
+- **The label keeps inner quotes** (MINOR `e585ce27`, `lib/parsers/arg-parser.mjs` `tailOf`; decision 88). `tailOf` strips quotes only when one pair wraps the whole rest, so `brief.md "Session 2" of "3"` gives the label `"Session 2" of "3"`.
+- **The Bash guard knows one heredoc delimiter** (MINOR `8959d2cd`, `hooks/scripts/pre-bash-executor.mjs`; decision 88). It has no general rule for a quoted heredoc's closing line, so another heredoc in the commands, such as a stats record's, can still be closed early by a typed line equal to its delimiter.
+- **A command that mentions the parser's heredoc opener with a line after it stays blocked** (fix round 4.5b part 2, decision 88). The guard checks every opener of `VOYAGE_ARGS_EOF_7F3C9E` that has a non-blank line after the opener's line, so such a command stays blocked unless it is a quoted heredoc whose closing line is the one last non-empty line, for example a commit message written as a heredoc that mentions the opener. Write it on one line, or read it from a file. Two kinds of such command pass, under the conditions the ESC and SLT bullets above give: one whose opener's first `<` follows an odd run of backslashes, unless two escaped `<` in a row name the delimiter (see EVL), a case fix round 4.5b2 part A widens, and one whose opener is text inside a string on its line, unless a backslash-newline splits it (see SIS).
+- **A `bash -c $'...'` command on one physical line is not checked** (fix round 4.5b part 2, decision 88). It carries no literal newline, so the guard sees no line after the opener even when `bash -c` expands it into a heredoc of the parser's delimiter; part 1 blocked it by accident. The shipped commands never produce it from `$ARGUMENTS`.
+- **The tokenizer splits a quoted value at a quote of the same kind that starts a word** (TOK, decision 88). `'the '90s were great'` gives `'the` and `90s were great` (accepted by the operator on 2026-10-27, part 2's brief). The argv form's self-quoting of a word that holds spaces (`-- 'say "hi"'`) splits (accepted on 2026-10-28). Since part 3, a quoted value that ends in whitespace pairs again, so such a value may also hold what follows it up to a quote that ends a word: `--project "x --since " HEAD` gives `--project` = `x --since `. Review finding `564d6dff` (decision 90) names this case: such a value can swallow a later flag with no error.
+- **`gitEntryDir` does not follow git's `GIT_CEILING_DIRECTORIES` rules** (MAJOR `3b98d18b`, `lib/review/recurrence.mjs`; decision 89). It resolves the entries after an empty one through realpath, and it keeps relative entries and entries whose realpath fails. So a ceiling written that way can give `no-git-repo` and a written pointer where git sees a repository.
+- **A failed checkpoint commit leaves `{hash}` on the previous step's commit** (MAJOR `69b086eb`, `commands/trekexecute.md`; decision 89). When the checkpoint commit fails, `{hash}` is the current HEAD, which is the previous step's commit. So the done line and the progress record name a commit without step N's changes.
+- **Some typed arguments that hold `<<` are refused** (fix round 4.5b part 3, decision 89). A typed argument holding `<<` followed by a word the guard cannot read, other than through a quote with no partner (for example `<<$'\t'` or a backslash inside `"..."`), is refused by `/trekreview`, `/trekcontinue` and `/trekendsession`; write the argument another way.
+- **Part 3 added a reader rule without a plan revision** (MAJOR `4a880f70`, `hooks/scripts/pre-bash-executor.mjs`; decision 90). Part 3's execution added the reader rule for a `$` followed by a backslash-newline and a quote (the word is unreadable) without a plan revision; it stays, and part 4 runs its pins under `npm test`.
+- **Part 3 compares the opener's word after `trim()`** (MAJOR `fb643fb0`, `hooks/scripts/pre-bash-executor.mjs`; decision 90). Part 3's execution compares the opener's word after `trim()`, not exactly as its plan said, without a plan revision; it stays, pinned the same way.
+- **An unreadable opener gets the unquoted reason** (MAJOR `73eed642`, `hooks/scripts/pre-bash-executor.mjs`; decision 90). An opener blocked because its word cannot be read is given the unquoted reason and told to open the heredoc quoted, also when its word is not the delimiter and the argument heredoc is already quoted; write the argument another way.
+- **Part 3's entry did not name the false stops of a string-borne `<<`** (MAJOR `6f09b931`, `CHANGELOG.md`; decision 90). Part 4's SLT bullet lets most of them through, and a command whose string opens on an earlier line than its `<<`, for example a commit message heredoc whose quoted text spans two lines, is still refused.
+- **An error inside the guard is reported as the command's fault** (MAJOR `161545f6`, `hooks/scripts/pre-bash-executor.mjs`; decision 90). An error inside the guard's own reading is reported as an unquoted opener whose word could not be read, which blames the command for the guard's fault.
+- **The guard re-splits the command for each candidate opener** (MINOR `fe3fe55b`, `hooks/scripts/pre-bash-executor.mjs`; decision 90). For each candidate opener the guard re-splits the command to find its line, quadratic work on a large command.
+- **The guard keeps its narrow reader** (MINOR `03df3b0b`, `hooks/scripts/pre-bash-executor.mjs`; decision 91). The narrow reader is kept; a full reader that reads the command from start to finish like the shell is deferred (decision 92).
+- **The guard's test files copy the same helpers** (MINOR `78040bd7`, `tests/hooks/bash-guard-false-stops.test.mjs`; decision 91). The Bash guard's test files copy the same helpers (`ARGS_DELIM`, `ARGS_RULE`, `PARSER_LINE` and others) instead of sharing them, so a change to the block message means editing every copy.
+- **`argsShellOpeners` keeps an unused default parameter** (MINOR `49873813`, `hooks/scripts/pre-bash-executor.mjs`; decision 91). Its second parameter defaults to `argsEscapeLimit(text)`, and its one caller always passes it.
+- **A simplify commit has no scope** (MINOR `79402171`, `hooks/scripts/pre-bash-executor.mjs`; decision 91). Part 4's commit `9b80e6c` (`refactor: simplify pass (trekexecute)`) has no scope after its type; it is already pushed, so it stays.
+- **A grep pattern that puts the delimiter right after `<<` inside a string is refused** (MAJOR `943f9841`, `hooks/scripts/pre-bash-executor.mjs`; fix round 4.5b2 part A, decision 122). A grep pattern that puts the delimiter right after `<<` inside a string, with a line after the command, is refused although the shell reads the `<<` as text; the regex reading does not skip a `<<` the shell reading skips. Fixing it was dropped from part A: each version of the fix that was planned or built let through some command that part 4 blocks and that a nested shell or zsh then runs. A test pins the command as refused (`tests/hooks/bash-guard-4-5b2-a-known.test.mjs`).
+- **A string whose `<<` follows a quote of the other kind or an escaped quote is refused** (MAJOR `a6735ef9`, `hooks/scripts/pre-bash-executor.mjs`; fix round 4.5b2 part A, decision 122). A string whose `<<` follows a quote of the other kind or an escaped quote (the review's commit message with a second `-m` that spans two lines, and its `echo "x\"y" && grep "<<" …` with a line after it) is refused, because the string test counts one quote character from the line start. Fixing it was dropped from part A: each version of the fix that was planned or built let through some command that part 4 blocks and that a nested shell or zsh then runs. A test pins each command as refused (`tests/hooks/bash-guard-4-5b2-a-known.test.mjs`).
+- **Other spellings of the heredoc operator for a second shell still pass** (fix round 4.5b2 part A, decision 107). Other spellings that build the parser's heredoc operator or word for a second shell still pass and expand or close early: a quoted `<<` next to the word (`'<<'`), `<` and `<` in two strings, the word held in a variable, an empty quote pair before the word inside a string (decision 125), and a form on one physical line. Only `\<\<` with a line after it is checked (EVL), and it is checked with or without a second shell, so `\<\<` before the word with a line after it is refused even where no shell reads it again.
+- **The escape scan models default shell options only** (fix round 4.5b2 part A, decision 124). Text before the escaped run that changes how the shell reads quotes, aliases or expansions (`setopt`, `emulate`, `set -o`, `shopt`, an alias) is not followed: for example `shopt -s expand_aliases`, an alias `q` for `bash -c "`, and `q echo x \\\<<…` with a body line and the closing line passes since part A, and `/bin/bash` expands the body (with `set -o posix` too); zsh does not.
+- **A split opener inside a string or a quoted heredoc's body is refused** (fix round 4.5b2 part A, decision 123, widened by decision 126). A `<<` whose opener a backslash-newline splits is refused inside a string or in the body of a quoted heredoc that passes when a line follows it, also where the shell reads it as text.
+- **The quote scan's signature differs from part A's plan** (MAJOR `227985d4`, `hooks/scripts/pre-bash-executor.mjs`; part A's review, decision 127). The simplify pass dropped the unused `from` parameter of `argsQuoteScan`, while the plan's text still gives five parameters. Behaviour is unchanged: the one caller always passed 0 and a scan state.
+- **The split-suffix branch's pass exits have no test** (MAJOR `90e253d3`, `hooks/scripts/pre-bash-executor.mjs`; part A's review, decision 127). Every test of a split delimiter with a suffix expects a block; none shows that a quoted one closing once at the end, or one with no body line, passes as the same opener written out does, so a change that refuses them would leave the suite green.
+- **A `<<-` heredoc closed by a tab-indented line before an escaped run has no test** (MAJOR, the review's finding at `hooks/scripts/pre-bash-executor.mjs:462`; part A's review, decision 127). The quote scan strips leading tabs from the closing line of a `<<-` heredoc, and no test combines that with a later escaped `<`; if the strip were lost, such a command would be refused again without a test failing.
+- **An error in the shell reading hides the regex reading's reason** (MAJOR `3890ec2b`, `hooks/scripts/pre-bash-executor.mjs`; part A's review, decision 127). The shell reading now runs first, so an error in it blocks with the unquoted, unreadable reason even where the regex reading would have named the early close. The command is still blocked; only the reason is wrong.
+- **More spellings of the operator for a second shell pass** (MINOR `402a9416` and `0464e12e`, `hooks/scripts/pre-bash-executor.mjs`; part A's review, decision 127). Measured by the review: quoting inside the delimiter word (`VOYAGE"_ARGS…"`, `VOYAGE\_ARGS…`), a `$'…'` word, and an escaped `<` next to a quoted one (`\<'<'`, `'<'\<`) after `eval cat` pass the guard, and `/bin/bash` and zsh expand the body. The check reads one spelling of the operator and a prefix-stripped word, not the word as a second shell reads it; the mechanism goes to the 4.5c structure review with the full reader.
+- **Smaller findings of part A's review** (MINOR `397b32ae`, `179386c4`, `73f6727b`, `75c439ab`, `f9ee4fd4`; decision 127). A second, weaker word reader next to the shell reading's word loop; the split-opener rule repeated in three places; the suffix branch repeating the regex reading's quoted test and body lines; a per-opener copy of the rest of the command in the re-read check; and this round's simplify commit `cc277c4` again without a scope. The corpus test's case with the guard switched off also passes on a corpus run killed at its timeout.
+- **A MAJOR at an unchanged caller can be marked pre-existing** (part B, Requirements Check 6). The pre-existing mark reads only the lines the range added or changed, so a MAJOR at an unchanged caller that a changed signature broke is marked pre-existing and needs no answer. Lines on both sides of a pure deletion count as changed. A BLOCKER or a security finding there still counts in full.
+- **`/security-review` re-raises run-range findings in round 2** (part B). The engines stay on the run range from round 2, because `/security-review` takes no range, so it raises its findings from the whole run again. Carry folds each into the previous finding it matches: it is carried, not counted as new, and it stays open while the engine raises it.
+- **Review answers cannot be recorded with the installed 6.5.0 plugin** (part B). Its `/trekreview` has no answers step, and its review stays at 1.1. This delivery's own review runs on 6.5.0, so before its release check the operator answers its MAJORs with this repo's `lib/review/review-answers.mjs` (`pending`, then `record`), the path `docs/release-runbook.md` gives.
+- **The fork point is read from a ref the session can move** (part B). `lib/review/pre-existing.mjs` reads the fork point from `refs/heads/main` (or `master`), and that ref can be moved with `git update-ref`, `git branch -f` or a plain commit on main before the branch is made; the Bash guard does not ask about any of them, so the binding is a trace, not a signature.
+- **The Bash guard lets some commands with a quoted value through unasked** (part C, decision 137). The guard's view of a command loses a quoted value that holds a space or is empty, so the option before it takes the next word as its value, and a merge into main, a push, a tag or a publish is not asked about. Measured with the guard's classifier (`classifyGitApproval`), each of these gives no question: `git tag -m "Release one" v1.0`, `git -C "/tmp/a b" push origin main`, `git -c "x.y=a b" push origin main`, `echo "a b"#; git push origin main`, `git tag -m '' v1.0`, `git -C ~/"My Repos"/x merge --no-ff feat`, `npm --workspace "$WS" publish`, and `git -C "<path with a space>" merge --no-ff feat`, the form `/trekexecute` Phase 8 merges with when the repo path holds a space. The hole is on main already, and part B's merge does not widen it. Under decision 137 the fix gets its own round with its own brief, where the mechanism is chosen on purpose.
+- **The merge question and the gate have rests from part B's review, round 2** (part C, decision 131). Each was answered as accepted in that review and goes to the next hardening round. The merge question can mislead in its text only; the guard still asks: a quoted `-m` value with spaces before two branches (`git merge -m "merge two" a feat`) shows feat's run evidence for a merge of both; without a `## Doors` list in the plan and without a new CHANGELOG section, the undo line takes the door of the previous section; a loose ref that is not a plain sha falls back to an older `packed-refs` entry. The gate stays closed but says the wrong thing: an approval log that cannot be read or checked gives `review-unanswered:` instead of "not measured", so the release check says "not ready" instead of "could not decide". R6 now reads a review as stale after a merge of a side branch forked before the review, even when its content is allowed (stricter, never greener). When a carried finding has a severity word outside the four known ones, the carry keeps that word instead of ranking it highest, so a MAJOR could leave the count; no known path writes such a word, and the gate does not refuse one. The writer's refusal of a name that is an entry in the git directory has no test of its own. On a review with a duplicate finding id, `review-answers.mjs pending` exits 1 with an empty list, so Phase 8.8 asks nothing; the merge stays closed.
+- **Copies and repeated work in the review code** (part C, decision 131). `RECORD_KEYS` in `lib/review/reviewed-commit.mjs` copies the approval log's private field list; the answers-table reader in `lib/review/review-answers.mjs` copies the validator's and already treats a duplicate row differently; the guard's evidence reader copies the git-directory lookup of `hooks/lib/git-approval.mjs` (with `lstat`, so a `.git` link gives "no run evidence"); callers tell an unanswered MAJOR from "not measured" by the reason's prefix; `recordAnswer` validates `--store` but commits the log without it; without `--repo` the gate starts git three times for the same top level.

+- two-way: every case in `evals/` names its event, and the routing test checks every case (P10, R1) — a revert lets a case without `from=` through again; the eight tags added to the fixed test set stay harmless.
+- two-way: the coupling to Claude Code's `run` and the built-in owner list (R2) — a revert removes the three sentences and makes `owner=run` an unknown owner again; the criteria runner and `End-to-end:` are unchanged.
+- two-way: skill annotating and its pointers in three commands (order B) — revert the commit; the
+  script, the page, the stored notes and the approval checks are unchanged.
+- two-way: fix round 4.5a (decisions 57, 67, 68) — a revert restores the old texts and checks
+- two-way: fix round 4.5b (decisions 80 to 87) — a revert restores the old checks, texts and red script and takes out the Bash guard's heredoc rule; `review.md` keeps `review_version` 1.1 either way.
+- two-way: fix round 4.5b part 2 (decision 88) — a revert restores part 1's four behaviours (the tokenizer's quote search, the guard's refusal of a one-line mention, the pointer written on any `git check-ignore` exit 128, the undefined `{hash}`) and the guard's first-opener-only check.
+- two-way: fix round 4.5b part 3 (decision 89) — a revert restores part 2's closing-quote search (a value whose closing quote follows whitespace splits again) and the guard's regex-only opener check.
+- two-way: fix round 4.5b part 4 (decision 90) — a revert restores part 3's literal-delimiter gate and its refusal of a heredoc operator inside a string or after a backslash; the catch-branch test and the TOK wording go with it.
+- two-way: fix round 4.5b2 part A (decision 91, decision 107, decision 123) — a revert restores part 4's whole-command escape limits, the exact-word check for a split delimiter, the string and body skips of a split opener and the unchecked twice-escaped operator; the corpus, the end-to-end script, the keep-assertion test and the corrected test header go with it.
+- two-way: review gate 4.5b2 part B — `review_version` 1.2 and the answered-MAJOR merge lock (decisions 93-105, 128); a revert restores the 1.1 gate, 1.2 files still read under the old validator (unknown keys tolerated), and K2 `review` records keep the record shape.

-|-------|----------|
-| `open` | Skip optional checkpoints. The pipeline runs end-to-end with the fewest interruptions. Suitable for trusted briefs in clean repos. |
-| `closed` | Stop at every checkpoint. The operator confirms each transition. Suitable for high-stakes work or unfamiliar repos. |
-| `adaptive` (default) | Stop only when the autonomy-gate state machine reports a meaningful boundary (manifest-audit FAIL, plan-critic BLOCKER, main-merge gate). Best balance of velocity and safety. |
+All four pipeline commands accept `--gates [true|false|closed|open]`. A bare `--gates`, `true` or `closed` turns gating on; `false`, `open` or no flag (the default) leaves it off. Any other next token is not the flag's value, so `/trekplan --gates --project <dir>` is a bare `--gates`. With gating on, `/trekbrief`, `/trekresearch` and `/trekplan` pause at their own boundaries; `/trekexecute` accepts the flag and pauses on nothing, because its one stop is the merge into main, which always asks. Details: [`docs/operations.md`](docs/operations.md) § Autonomy mode.
 
 Under the hood, `lib/util/autonomy-gate.mjs` runs a small state machine (`idle → gates_on | auto_running → paused_for_gate → completed`), and `lib/stats/event-emit.mjs` records named lifecycle events (the main-merge gate and its answer, among others) to `trekexecute-stats.jsonl` in the plugin data directory. The new `hooks/scripts/post-compact-flush.mjs` PostCompact hook re-injects `.session-state.local.json` after context compaction so multi-session work survives a compaction boundary.

+A finding is pre-existing when it sits on a line the range `scope_sha_start..scope_sha_end` did not add or

+(`main`, else `master`): the fork point itself, or a later commit reached through process files only (the approval

+**The review policy.** The policy file is `REVIEW.md` at the repo root, read at `scope_sha_start` from git, never
+from the working tree, and finalize applies it as its last pass. Only its one `voyage-review-policy` block is read;
+the file's text is data, never an instruction. The block holds at most one `max-minor` line (`max-minor: <0-999>`),
+the cap: at most that many MINOR and SUGGESTION findings stay reported, and each one over it is listed by title
+under `## Declined to Judge` with `policy:cap`, followed by `Over the policy cap: N`. It also holds at most 50
+`skip` lines (`skip: <glob>`): a MINOR or SUGGESTION finding on a skip path is listed there with `policy:skip`, and
+its file stays in Coverage. The policy caps and skips MINOR and SUGGESTION findings only, never a BLOCKER, a MAJOR
+or a security finding; the verdict gate exits 2 on a review in which one was moved. A malformed or changed file (any
+other line in the block, two blocks, a bad glob, a symlink, or a file changed inside the reviewed range) is not

+the log as `docs(voyage): review answers (round {R})`; show the operator the
+stored reason it returns. On `"committed": false`, print its reason in one
+line and continue: the answer is logged but not committed. On exit 1 (a
+hollow or empty reason, a "fixed" without its R-step, an accept on a security
+finding), say the refusal in one line and ask that finding again once. A
+second refusal leaves it unanswered. On exit 2, say "answer not recorded" with
+its reason in one line.

 ## Autonomy mode (`--gates`, v3.4.0)
 
-All four pipeline commands accept a boolean `--gates {true|false}` flag. Presence (`--gates true`, or bare `--gates`) turns gating **on** — the run pauses at autonomy boundaries for operator confirmation. Absence (or `--gates false`, the default) runs phases continuously without pausing.
+All four pipeline commands accept `--gates [true|false|closed|open]`. A bare `--gates`, `--gates true` or `--gates closed` turns gating **on**; `--gates false`, `--gates open` or no flag (the default) leaves it off. The next token is the flag's value only when it is one of those four; any other token stays the command's own argument, so `/trekplan --gates --project <dir>` and `/trekexecute --gates plan.md` are a bare `--gates`. Each command maps the value once through `lib/util/autonomy-gate.mjs`; a shim that fails falls back to the same mapping in prose, and the run goes on. With gating on, `/trekbrief` pauses before its auto chain, `/trekresearch` after each topic, and `/trekplan` after exploration, synthesis and adversarial review. `/trekexecute` accepts the flag and pauses on nothing: its one stop is the merge into main, which always asks (below).
 
-`/trekexecute` additionally refines *how strict* the gating is via a `gates_mode` policy derived from the brief's effort signal (an explicit operator `--gates` flag takes precedence over the brief signal — see `commands/trekexecute.md` § High-effort behavior (v5.1.1)):
-
-| `gates_mode` | Derived from (effort) | Behavior |
-|--------------|-----------------------|----------|
-| `adaptive` | standard / absent (default) | Stop only at meaningful boundaries (manifest-audit FAIL, plan-critic BLOCKER, main-merge gate) |
-| `closed` | high | Stop at every autonomy boundary; operator confirms each transition |
-| `open` | low | Skip optional checkpoints; trust manifests + verify gates only |
-
-Under the hood: `lib/util/autonomy-gate.mjs` runs the state machine `idle → gates_on | auto_running → paused_for_gate → completed`. `start` routes to `gates_on` when `--gates true`, else `auto_running`; a `phase_boundary` from `gates_on` pauses at `paused_for_gate` (awaiting `resume`); `finish` reaches the terminal `completed`. The module is pure data with no I/O. Separately, `lib/stats/event-emit.mjs` records named lifecycle events (`brief-approved`, `main-merge-gate`, `main-merge-approved`, `main-merge-declined`, `gates_mode_flag_override`, `user_input`) to `trekexecute-stats.jsonl` in the plugin data directory (`CLAUDE_PLUGIN_DATA`, else `~/.claude/plugins/data/voyage-ktg-plugin-marketplace/`, the directory `scripts/yardstick.mjs` reads); a write that fails is reported, never skipped. The main-merge gate is the final autonomy boundary before HEAD lands on `main`.

The main-merge gate is the final autonomy boundary before HEAD lands on `main`.
 
 **The main-merge gate is a lock, and the guard asks the one question** (operator decision 2026-10-08). The gate opens only when the run is `completed` and the review's verdict gate (`lib/review/verdict-gate.mjs`, K7) exits 0; BLOCK (1) and "could not decide" (2) keep it closed. When it opens, `/trekexecute` runs the merge into main itself and `pre-bash-executor` answers "ask" before it runs, in auto mode too, so that question is the only one. In the permission mode where Claude Code shows no prompts, the guard refuses the merge instead, and every other call it would ask about (push, tag or publish, destructive git), since no one can be asked (operator decisions 2026-10-09). The executor no longer asks "ready to merge?" first, and `--gates` no longer adds a pause before the wave merge-back: the guard asks there as well, once per session, because the push and the merge go in one call. Before this, one merge cost two questions in three places: the `--gates` pause before the wave merge-back, the gate's own question after the waves were merged, and the gate's question on the single-session path followed by the guard's at the merge itself.

+
+## Steps
+
+### Step 1: Store tags with a sign-up
+- Files: `src/signups.mjs`
+- Changes: `add(name, dish, tags = [])` stores `tags` on the record; unknown tags are refused.
+- Test first:
+  - File: `tests/signups.test.mjs`
+  - Verify: `npm test`
+
+### Step 2: Parse tags on the command line
+- Files: `src/cli.mjs`
+- Changes: `add <name> <dish> --tags vegan,gluten-free` splits on commas and passes the list on.
+- Test first:
+  - File: `tests/cli.test.mjs`
+  - Verify: `npm test`
+
+### Step 3: Print tags in the list
+- Files: `src/cli.mjs`
+- Changes: `list` prints `name<TAB>dish [tag, tag]`; a sign-up with no tags prints as before.
+- Test first:
+  - File: `tests/cli.test.mjs`
+  - Verify: `npm test`
+

+// bodies (hooks/lib/bash-view.mjs). The check runs when the command names the
+// delimiter once every backslash-newline is removed: the shell removes a
+// continuation inside the opener's word, and an unquoted body with no closing
+// line is still expanded (fix round 4.5b, part 4).
+// Every opener in the command is read in two ways, and the command is blocked
+// when either reading blocks it (the union):
+//   1. A regex finds <<D, <<'D', <<"D" and <<\D, with an optional - and
+//      spaces (fix round 4.5b and its part 2).
+//   2. A shell reading (fix round 4.5b, part 3) starts at every < in the
+//      text, wherever it stands; like the regex, it does not lex the command
+//      around it. A backslash directly followed by a line break is a
+//      continuation: removed, not quoting. The word after << (and an optional
+//      -, spaces and tabs) is read as the shell reads it: a backslash makes
+//      the next character literal and quotes the word; '...', "...", $'...'
+//      and $"..." quote it, so a partly quoted word such as
+//      <<"VOYAGE"_ARGS_EOF_7F3C9E counts. The word ends at unquoted
+//      whitespace (a line break included),
+//      at one of ; & | ( ) < > or at the end of the text. Its body lines are
+//      the raw lines after the line on which the word ends: continuations
+//      change only how the word is read, never the line count.
+// bash reads a heredoc body only from the lines after the opener's line, so
+// an opener with no non-blank line after it (a one-line grep or commit
+// message that only mentions it) has no body: nothing can close early and an
+// unquoted opener has nothing to expand, so it is skipped. An opener with a
+// non-blank line after it is blocked unless it is quoted (its body is not
+// expanded) and exactly one line, trimmed, equals the delimiter with every
+// line after that one empty (the regex reading counts every line of the
+// command, the shell reading the body lines).
+// A word the guard cannot read is treated as unquoted, whatever its letters:
+// a quote with no partner anywhere in the rest of the text (the word is cut
+// there, so its line is the quote's line), any backslash inside "...",
+// $"..." or $'...' (no escape there is decoded), a backslash at the end of
+// the text, a - reached only after a continuation (bash reads <<-, zsh
+// reads the - as part of the word), and a continuation between a $ and the
+// quote it opens. The word is compared with the delimiter after trim(), the
+// same trim the body lines get, so a CR (a CRLF line), VT, FF or other
+// character trim() strips around the word does not hide it.
+// After a quoted opener that passes, a later opener is skipped only when its
+// word is cut by an unpaired quote and is readable otherwise and not split by
+// a backslash-newline (fix round 4.5b2, part A, decision 126): the shell meets
+// the same unpaired quote, stops with a parse error and runs nothing after it,
+// so a typed argument such as fix "<<" handling passes. Every other later
+// opener is checked, because the accepted opener may sit inside a string and
+// must not hide a real opener after it.
+// Two kinds of << are text to the shell and are skipped (fix round 4.5b,
+// part 4):
+//   - A cut word whose quote closes a string opened earlier on its line (an
+//     odd count of that quote from the line start to the opener's first <),
+//     as in grep -n '<<' or a commit message holding "<<". A cut word with
+//     no string open before it stays unreadable and is blocked as unquoted.
+//     The quote has no partner, so the outer shell never reads the word's
+//     body as a heredoc body; a second shell (bash -c, eval) may, and the
+//     regex reading still reads such a << when the delimiter follows it. An

+//     it is never skipped (fix round 4.5b2, part A, decision 123). Each
+//     opener is read on its own, so skipping one hides no later opener.
+//   - A < after an odd run of backslashes (counted on the raw text, a line
+//     break ends the run) starts no opener, in the regex reading and in the
+//     shell reading alike, when a quote scan of the text before the run ends
+//     outside every quote and every heredoc body. The scan skips a closed
+//     '...' or "..." string, a here-string and the body of a heredoc closed
+//     before the run, so none of these turns the rule off. A quote still open
+//     before the run, a heredoc not closed before it, and text the scan
+//     cannot follow (for example $' or $", $( ${ $[, a backquote, a (, a #, a
+//     continuation, a heredoc word it cannot read, a second < on a heredoc's
+//     line, a body line of an unquoted heredoc that ends in a backslash) keep
+//     the rule off: there the shell may read the backslashes once more
+//     (inside a backquote, or in a heredoc body fed to a shell, measured), so
+//     the < is read as unescaped. The regex reading takes the shell reading's
+//     decision for the same <. The < after the escaped one is read as usual,
+//     so a << right after it is still checked (fix round 4.5b2, part A).
+// A < followed (continuations skipped) by an odd run of backslashes and a
+// second < is a heredoc operator a second shell may read: the outer shell
+// removes the backslashes, so eval, bash -c or sh -c reads << there. It is
+// blocked as an unquoted opener the guard could not read when the word after
+// the second < names the delimiter as a second shell reads it (every
+// backslash-newline removed, then a leading -, blanks, quotes and
+// backslashes) and a non-blank line follows anywhere after the opener's line
+// (the body may sit inside the quotes that carry the word). It is judged
+// before every skip. A one-line form has no such line and passes. The rule
+// does not look for the second shell, so the same text with none is blocked
+// as well (fix round 4.5b2, part A, decision 107).

+// round 4.5b2 part B): the code-correctness reviewer checks the diff against
+// exactly this set (rule keys CLAUDE_MD_DEVIATION and CLAUDE_MD_STALE, MINOR),
+// and lib/review/review-finalize.mjs sets aside under Declined to Judge
+// (`instruction-out-of-set`) a finding under those keys that cites a file
+// outside it.
+//
+// `instructionSet(repo, sha, changedPaths)` reads the tree of the reviewed
+// commit with `git ls-tree -r -z --full-tree`, so only a file tracked at that
+// commit can enter the set (never an untracked file, never one committed
+// later, never a file outside the repo such as a global ~/.claude/CLAUDE.md):
+//   - the root `CLAUDE.md` and `AGENTS.md`;
+//   - the same names in each ancestor directory of each changed path (a
+//     changed path that is absolute, holds `..`, `.`, an empty segment or a
+//     backslash names no directory of the repo and adds nothing);
+//   - every `.md` file under the root's `.claude/rules/` at any depth
+//     (`.claude/rules/sub/x.md` included), the test `isInstructionFile` uses;
+//   - the same under `<dir>/.claude/rules/` for each such ancestor directory
+//     `<dir>` of a changed path (`pkg/.claude/rules/x.md` only when a changed
+//     path lies under `pkg/`).
+// An entry with mode 120000 (a symlink) has its target read with
+// `git cat-file`. A target resolved against the link's directory that stays
+// inside the repo and is a tracked regular file enters the set next to the
+// link, which keeps its own name (CLAUDE.md -> AGENTS.md gives both paths);
+// any other target (absolute, out of the repo, missing, another link) drops
+// the entry, link name included.
+// Every path is repo-relative posix. A git failure, or a sha that is not a
+// full commit id, gives `{ok:false, reason}`.
+//
+// `isInstructionFile(path)` is the deep-review classifier of /trekreview
+// Phase 4: the base name is `CLAUDE.md` or `AGENTS.md` at any depth, or the
+// path is a `.md` file under a `.claude/rules/` directory. `docs/**` is
+// included, so a changed instruction file there gets deep review although the
+// triage table makes the rest of `docs/**` summary-only.
+//
+// `changedPaths(repo, start, end)` is the changed-path list the filter in
+// lib/review/review-finalize.mjs builds the set from: the paths of
+// /trekreview Phase 5's `git -c core.quotePath=false diff --name-only`, here
+// NUL-separated and with flags no repo config changes (`--no-relative`,
+// `--no-ext-diff`, `--ignore-submodules=none`, `--no-renames`). A deleted path
+// is listed (its directory's CLAUDE.md is in the set the reviewer was given),
+// and `--no-renames` lists both sides of a rename, so the filter's set always
+// holds the prompt's set.
+//
+// CLI:
+//   node lib/review/instruction-scope.mjs --set --repo <d> --sha <s> --changed <file>
+//     <file> holds the changed paths, one per line (`git diff --name-only`).
+//     Prints {"ok": true, "files": [...]}; exit 0. A git failure or bad
+//     arguments print {"ok": false, "reason"}; exit 2.
+//   node lib/review/instruction-scope.mjs --triage <paths...>

+//   <git common dir>/voyage/merge-evidence/<branch head sha>.json
+// The Bash guard (hooks/scripts/pre-bash-executor.mjs, through
+// hooks/lib/merge-evidence.mjs) reads it into the two lines of its merge
+// question: how the run was tested, and how the merge is undone.
+//
+// Every field is derived from artifacts, never from an argument the model types:
+//   - branch_head_sha: `git rev-parse --verify refs/heads/<branch>`;
+//   - end_to_end: the plan's first `End-to-end:` backticked command, with exit
+//     0 when progress.json says `end_to_end: verified`, else null;
+//   - verification: progress.json `plan_verification.summary` passed/total;
+//   - review: the verdict gate (`decideVerdictFile` with the repo, R6 first)
+//     on {project}/review.md, and its `scope_sha_end` (`reviewedSha`); a review
+//     the gate does not decide (exit 2) has a null verdict. The gate is asked
+//     only when `git rev-parse --verify HEAD` in --repo is the branch head (R6
+//     is HEAD-based); from any other HEAD the verdict is null ("not measured"
+//     on the question) and `review.sha` is still written;
+//   - door: the plan's `## Doors` list, else the CHANGELOG's first section when

+// lib/review/pre-existing.mjs
+// Pre-existing findings (review_version 1.2, fix round 4.5b2 part B): a
+// finding on a line the review range did not add or change. The mark is read
+// from git and never trusted as written: `lib/review/review-finalize.mjs`
+// writes it (`markFindings`), and the verdict gate re-derives it
+// (`preExistingCheck`) before a MAJOR leaves the answer set. A BLOCKER or a
+// security finding counts in full whatever the mark (lib/review/review-answers.mjs
+// `countingMajors`); every uncertain case counts as new.
+//
+// The line sets come from one `git diff -U0` of `scope_sha_start..scope_sha_end`
+// with flags that no repo config changes (`--no-color`, `--no-ext-diff`,
+// `--no-textconv`, `--no-relative`, `--find-renames`, explicit prefixes,
+// `--ignore-submodules=none`, `core.quotePath=false`):
+//   - added or changed lines are `c..c+d-1` of each `@@ -a,b +c,d @@`;
+//   - a pure deletion (`d = 0`) marks lines `c` and `c+1` (both sides of it);
+//   - a new or binary file is `'all'`;
+//   - a renamed or copied file goes into `renamed` under both names.
+// Any git failure, ENOBUFS, a range whose start is not a proper ancestor of its
+// end, or a line the reader cannot parse (a quoted path included) is
+// `{ok:false}`: then nothing is pre-existing.
+//
+// A finding's path and line must also be in the tree at `scope_sha_end`: the
+// path, byte for byte, names a regular file there (mode 100644 or 100755, read
+// once with `git ls-tree -r -z --full-tree`), and the line lies inside that
+// file's line count. A path the diff does not name is otherwise taken as
+// untouched; this check keeps a case variant (`A.mjs` on a case-insensitive
+// disk), a subdirectory-relative path, a missing file or a line past the end of
+// the file from passing as pre-existing. Any git failure here also means
+// nothing is pre-existing.
+//
+// The binding (fix round 4.5b2 part B, Step 14): `scope_sha_start` is read from
+// review.md, so it counts only when it is bound to the fork point from main
+// (`forkPoint`: `refs/heads/main`, else `refs/heads/master`, the rule of
+// `/trekexecute` Phase 8). Exactly two starts are bound (`startBound`):
+//   - the fork point itself;
+//   - a later start reached through process files only: the tree diff from the
+//     fork point to the start names only the approval log
+//     (`.claude/voyage/approvals.jsonl`, LOG_RELPATH) and paths under the
+//     top-level `.claude/projects/`, the commits `/trekbrief` and `/trekplan`
+//     make on the branch (lib/util/artifact-commit.mjs).
+// Every other start, and a range that ends on the main line itself, is
+// `{ok:false}`, so nothing is pre-existing. A finding on the approval log or on
+// a `.claude/projects/` file is never pre-existing, whatever the start. Limits:
+//   - a range that ends on the main line (a run committed straight to main, or
+//     a fast-forward merge), a start older than the fork point (the line sets
+//     are a tree diff, so a line main changed between that start and the fork
+//     point and the branch put back would not show), and a repo with neither
+//     branch have nothing pre-existing; a subdirectory project's own
+//     `{prefix}.claude/projects/` is not a process path (the stricter side);
+//   - trust limit: the fork point is read from `refs/heads/main` (or
+//     `master`), a ref the session that writes review.md can also move (`git
+//     update-ref`, `git branch -f`, or a plain commit on main before the branch
+//     is made), and the Bash guard does not ask about that. The binding narrows
+//     the forged start to a forged ref move as well. It is a trace, not a
+//     signature, like the K2 log;
+//   - BLOCKER and security findings are unaffected, as before: they count in
+//     full whatever the mark.
+//

+//   - it is not a security finding (a `security` catalogue key, or a finding
+//     from the `security-review` engine): those are never accepted;
+//   - the latest K2 record of kind `review` with subject
+//     `<review path relative to the git top level>#<id>` carries
+//     `answerSha(...)` over the review's CURRENT trailing JSON block and
+//     `scope_sha_end`, so an answer goes stale with the review it answers;
+//   - the row's Record is that record's hash.
+// A `fixed` row never answers: the finding stays open as fixed-pending.
+// A carried row (Carried from `review-round-<run>-<n>.md#<old id>`, written by
+// `carry` from round 2) answers a carried MAJOR only when all of these hold:
+//   - the finding is carried (`carried_from`) and, like the old finding in
+//     the archive, no security finding; the reason is not hollow;
+//   - `<run>` is the first 12 hex of this review's `scope_sha_start`, and `<n>`
+//     is lower than this review's `round` (no `round`: no carried link), so an
+//     answer from another run, or from a later round, is never carried;
+//   - the archive is a regular file beside review.md (read through
+//     `ctx.archived`), of the same run, and holds the old finding, which
+//     matches this one by the carry rule (lib/review/review-rounds.mjs
+//     `sameFinding`);
+//   - the archive's own `## Answers` row for the old id is that answer as
+//     given there (`accepted`, Carried from `-`, the same reason and Record);
+//   - the link is this finding's own carry chain: with `<n>` = round - 1 the
+//     old id is the finding's `carried_from`; with an older `<n>` the run's
+//     archive of round - 1 (its `round` field that number) holds the finding
+//     `carried_from` names, whose own row has the same link, Record and
+//     reason and is itself bound by these rules (one answer never answers
+//     another occurrence of the same class);
+//   - the K2 record with that hash is the latest of kind `review` for
+//     `<review path>#<old id>`, and its sha256 is `answerSha` over the
+//     archive's trailing JSON block, its `scope_sha_end`, the old id and the

+// A reason is always stored, hashed and compared normalized (`normalizeReason`),

+// lib/review/review-finalize.mjs
+// One deterministic pass over review.md after the coordinator and after
+// lib/review/fill-finding-ids.mjs, on both paths (review_version 1.2, fix
+// round 4.5b2 part B). Its passes run in the Architecture order (engine,
+// instruction, carry, pre-existing, policy), each at its place in PASSES:
+//
+//   - engine, always the first pass: `putBack` (lib/review/engine-compare.mjs)
+//     compares the engine payloads Phase 4.7 saved in the project folder
+//     (each regular `.review-engine-payload-*.json` whose top-level `reviewer`
+//     maps back through `ENGINES`, read with readdirSync) with the review's
+//     findings. Each engine finding at MAJOR or BLOCKER whose row no finding
+//     carries (its own row, or the row of its trimmed title) is appended at
+//     its own severity with `engine` kept and no id (the id recomputation
+//     gives it its computed id). It gets a `### ` entry under its
+//     `## Findings (<SEV>)` section with the line
+//     `**Source:** engine {name}, put back by the standard-path comparison`,
+//     the frontmatter list, counts, a verdict that is only raised, and, as a
+//     BLOCKER, its `### Step R<n>`. An engine finding in `out_of_scope` is
+//     not compared (it stays declined, `engine:out-of-scope`).
+//   - instruction, right after engine: a finding under `CLAUDE_MD_DEVIATION`
+//     or `CLAUDE_MD_STALE` whose `instruction_ref` is missing or names a file
+//     outside the repo's tracked instruction set (lib/review/instruction-scope.mjs
+//     `instructionSet` at `scope_sha_end`, for the paths changed over
+//     `scope_sha_start..scope_sha_end`) leaves the JSON findings, the
+//     frontmatter list, `counts` and its `### ` entry under
+//     `## Findings (MINOR|SUGGESTION)`, and goes to `declined_to_judge` with
+//     `instruction-out-of-set` and its `instruction_ref` (the cited file, or
+//     null); `## Declined to Judge` gets one line for it, by title, naming
+//     the cited file. A git failure or no range is an empty set, so every
+//     such finding is declined. Only a MINOR or SUGGESTION that is not a
+//     security finding moves; one whose entry is not found exactly once
+//     there, that an R-step names or that finalize added stays reported
+//     (stricter). The same breach reported by an engine and a reviewer
+//     (same triplet) was already merged by the coordinator's dedup, which
+//     keeps the higher severity.
+//   - carry (round 2 and later, `--previous <archive>`): `carry`
+//     (lib/review/review-rounds.mjs) keeps every previous finding that this
+//     round gives no positive evidence of being resolved, with `carried_from`;
+//     a current finding that matches one folds into it. What ran this round is
+//     read from the project folder, never inferred from what is missing:
+//     an engine ran when a regular `.review-engine-payload-*.json` there holds
+//     a top-level `reviewer` that maps back through `ENGINES`
+//     (lib/review/engine-findings.mjs), and a reviewer ran when its regular
+//     `.review-out-<reviewer>.md` passes the findings schema; that output's
+//     `previous: [{id, resolved}]` are its marks. The previous review's `ran`
+//     counts only when it is `finalized: true`. Writes `resolved` and a
+//     `## Resolved since round <n>` section just before `## Declined to Judge`.
+//   - pre-existing: `markFindings` (lib/review/pre-existing.mjs) sets
+//     `pre_existing` on every JSON finding from git over
+//     `scope_sha_start..scope_sha_end` (read raw, as `reviewedSha` reads; a
+//     YAML number or `null` means no mark), writes `pre_existing_counts`, and
+//     writes a `## Pre-existing` list (the count, then one line per title)
+//     just before `## Resolved since round <n>` or `## Declined to Judge`. It
+//     never moves or lowers a finding. A finding with `carried_from` keeps its
+//     line from the previous round's end, so it is never pre-existing
+//     (`pre_existing: false`, not judged against this range).
+//   - policy, always the last pass: `readPolicy` (lib/review/review-policy.mjs)
+//     reads `REVIEW.md` at `scope_sha_start` from git and `applyPolicy` caps
+//     and skips MINOR and SUGGESTION findings only (never a BLOCKER, a MAJOR
+//     or a security finding). A moved finding leaves the JSON findings, the
+//     frontmatter list, `counts` and its `### ` entry under
+//     `## Findings (MINOR|SUGGESTION)`, and goes to `declined_to_judge` with
+//     `policy:skip` or `policy:cap`; one whose entry is not found exactly
+//     once there, or that an R-step names, stays reported (stricter). The
+//     `## Declined to Judge` section gets one line per moved finding, by
+//     title, and `Over the policy cap: N` when a cap is set; the frontmatter
+//     gets `review_policy`, `review_policy_note` and `review_policy_sha256`
+//     (`none` without the file); `pre_existing_counts` and `## Pre-existing`
+//     keep only the findings still reported. A malformed, symlinked or changed file, or
+//     a git failure, applies no policy (`review_policy: not-applied`, the
+//     note says why). Coverage is not touched.
+//
+// Then, always last, the id recomputation: every id is computed again with
+// `computeFindingIds` (lib/parsers/finding-id.mjs) over the final array, and
+// any id that changed is rewritten with one simultaneous old -> new map,
+// applied in one pass so no rewrite chains: each JSON finding's `id`, the id
+// line of each body entry (its `### <id>` heading or `**ID:**` line), and each
+// `Source finding:` line; the frontmatter `findings:` list is written from the
+// final ids. A folded finding keeps the current finding's id until then, so
+// every reference to it, its R-step included, names the carried finding.
+// `carried_from`, `resolved` and `## Answers` values keep the previous ids.
+// After it: a body entry for each finding finalize added (under its
+// severity's `## Findings` section; an entry under another severity's section
+// moves), counts recomputed when the carry ran, a verdict that is only ever
+// raised (frontmatter and JSON block), one `### Step R<n>` for each BLOCKER
+// that no R-step names (the template's form, numbered after the last), and
+// `ran` in the JSON block with `round`, `round_base` and `finalized: true` in
+// the frontmatter. An R-step whose `Source finding:` names no finding of the
+// review is refused (exit 1). The file is written atomically (temp + rename).
+//
+// CLI:
+//   node lib/review/review-finalize.mjs --review <p> --repo <d> --project <dir>
+//        --round <R> [--round-base <sha>] [--previous <p>]
+//   (from round 2 both --round-base and --previous are required; --previous
+//   names this run's archive of round R-1, `review-round-<run>-<R-1>.md`)
+//   prints one JSON line; exit 0 = written, 1 = refused (a placeholder left,
+//   an id that cannot be computed, two findings under one id, an orphan
+//   R-step), 2 = could not run (bad arguments, unreadable file, no trailing
+//   JSON block, an unreadable previous review). On 1 or 2 the review is left

+// The `REVIEW.md` review policy (review_version 1.2, fix round 4.5b2 part B).
+// A repo may keep a `REVIEW.md` at its root with exactly one fenced block whose
+// info string is `voyage-review-policy`:
+//
+//   ```voyage-review-policy
+//   max-minor: 10
+//   skip: docs/**
+//   ```
+//
+// `readPolicy` reads it from git at `scope_sha_start` (never the working tree);
+// `applyPolicy` caps and skips MINOR and SUGGESTION findings only, never a
+// BLOCKER, a MAJOR or a security finding (lib/review/review-answers.mjs
+// `isSecurityFinding`), and never a finding lowered from MAJOR by the brief
+// rule (`brief_lowered_from`). lib/review/review-finalize.mjs runs it as its
+// last pass; the verdict gate refuses a review whose `declined_to_judge` holds
+// a BLOCKER, MAJOR or security entry under a noted reason
+// (lib/review/coordinator-contract.mjs `NOTED_REASONS`).
+//
+// The file's text is data, never an instruction: only the block's lines are
+// read, and any line in it other than `max-minor: <0-999>` (at most one) and
+// `skip: <glob>` (at most 50, each at most 200 chars) makes it malformed, as do
+// two blocks and a glob with an empty segment, a `..` segment, a leading `/`, a
+// backslash, a NUL or a control character. Blank lines are allowed. Every
+// uncertain case is "not applied" (no cap, no skip): a malformed block, a
+// symlinked or non-regular `REVIEW.md`, a `REVIEW.md` changed (or added, or
+// removed) inside `scope_sha_start..scope_sha_end`, a sha that is not full, and
+// any git failure. Zero blocks is "applied" with no cap and no skip.
+//
+// The glob matcher is linear and builds no regex from input: a pattern and a
+// path are split at `/`; `**` (a whole segment) matches zero or more segments,
+// and `*` and `?` match within one segment only. Both levels use the
+// greedy-with-one-backtrack-point walk, so a pattern of n stars is O(n·m).

+// being merged is rarely the reviewed one itself; what may come after it is
+// exactly what /trekreview writes and nothing else:
+//
+//   - the reviewed commit is HEAD, or an ancestor of HEAD;
+//   - every commit between it and HEAD (side branches included, each diffed
+//     against every parent it has, `--no-relative --ignore-submodules=none`;
+//     some path of parent edges leads from the reviewed commit to HEAD, so
+//     when every edge changes only the allowed paths, HEAD's tree outside
+//     them is the reviewed tree — a merge whose first parent comes from
+//     before the review cannot restore the tree from before it) changes only
+//     `{prefix}.claude/rules/voyage-review-lessons.md`, `{prefix}CLAUDE.md`
+//     and the approval log `.claude/voyage/approvals.jsonl` (LOG_RELPATH, at
+//     the git top level, never under {prefix}), where {prefix} is the
+//     project's place in the repo (`git rev-parse --show-prefix`);
+//   - in each such commit the lessons file is unchanged outside its managed
+//     block, every line its block gains is a lesson line (`validateLessonLine`)
+//     or exactly `BLOCK_HEADER` (m4), and CLAUDE.md is unchanged or gains exactly the pointer block
+//     (`withPointer` in lib/review/recurrence.mjs);
+//   - in each such commit the approval log only gains appended review answers
+//     (R6, fix round 4.5b2 part B): neither side is a symlink, the log after
+//     is mode 100644 (also when the commit creates it), the log before
+//     (empty when absent) is a byte prefix of the log after, and every added
+//     line is a K2 record with exactly the record fields and kind `review`,
+//     whose `hash` is its `recordHash`, whose `seq` follows the last record
+//     before it and whose `prev` links to it (to GENESIS on an empty log);
+//     any other change to the log is stale;
+//   - a commit with no parent in that range fails closed, and so does a
+//     symlinked CLAUDE.md (the pointer write goes through the link, so its
+//     target shows as a changed path).
+//
+// No CLI of its own: the command is `lib/review/verdict-gate.mjs --repo <dir>`,
+// which exits 2 (never green) with the reason when `checkReviewedCommit` is
+// not ok. Two kinds of reason (M4):
+//
+//   - `review-stale: …` — the gate looked, and the review is of another
+//     commit (or something else changed after it);

+name: annotating
+description: "The operator's own annotation loop for a Voyage brief, plan or review (a research document too, when asked): build the page with scripts/annotate.mjs so the person writes every note, take the pasted Copy Prompt back, and revise note by note. Fix and Change edit only the text the note points at; a Question is answered and changes nothing unless the person says so; nothing the notes did not ask for is edited. A note on ## Intent or ## Goal of an approved brief makes the approval stale, and a changed plan needs a new approval, said before the edit. The page is built again on the revised file. Use when someone wants to comment on, annotate or mark up a brief, plan, review or research document in the browser, or pastes back the notes from that page (Fix, Change, Question)."
+---
+
+# Annotating
+
+## Overview
+
+The annotation page lets the person read a Voyage artifact in the browser, click a line and write
+their own note, then copy every note back as one prompt. The loop is theirs: Claude builds the page,
+and later does what the notes say, no more. Two things go wrong without this skill. A Question gets
+answered and then written into the text as if it were a change. And the revision spreads: the same
+"fix" applied to parts no note named, a section rewritten to match, a new criterion added. Every such
+edit is a decision the person did not make, and on an approved brief or plan it also throws away an
+approval.
+
+## When to use
+
+- A `/trek*` command has just written a brief, plan or review and builds the page.
+- Someone says "let me comment on the plan", "I want to mark up the brief", "annotate this".
+- Someone asks to annotate a research document under `research/`. `/trekresearch` does not build
+  the page itself; build it on request.
+- The person pastes a prompt that starts "Please revise the voyage artifact at" and lists notes as
+  `[Fix]`, `[Change]` or `[Question]`.
+- Not for: someone who asks for Claude's own review of the artifact. That is a review
+  (`voyage:reviewing-adversarially`, `/trekreview`), not annotation.
+
+## Process
+
+1. **Build the page.** Run the script on the file and keep its stdout, the absolute path of the
+   page:
+
+   ```bash
+   ANNOT_HTML=$(node ${CLAUDE_PLUGIN_ROOT}/scripts/annotate.mjs "<path to the .md>" 2>&1)
+   ```
+
+   Print `file://<path>` and the line `open file://<path>`. If the script exits non-zero, say so in
+   one line and go on: the page is a convenience, never a gate.
+2. **The person writes the notes. Claude writes none.** Next to the link, say only how the page works:
+   click a line (or select a phrase first), pick Fix, Change or Question, write the note, and press
+   "Copy Prompt" when done; the notes stay in the browser if the tab is closed. No list of "points I
+   would look at", no summary of weaknesses, no suggested notes. Those would steer the notes the
+   person writes. If they want Claude's view as well, they ask for a review.
+3. **Read the pasted notes.** Each note has a number, a type, the section, the quoted text it is
+   anchored to, and the comment. Work from the quote and the comment, one note at a time.
+4. **Before any edit, check what the edit costs.**
+   - A brief with `intent_approved_hash` in its frontmatter, and a Fix or Change in `## Intent` or
+     `## Goal`: say in one line, before the edit, that the edit makes the approval stale, that
+     `/trekplan` halts until the new text is approved, and how to approve it
+     (`/trekbrief --approve <project dir>`). Then edit.
+   - A plan the person approved: any edit gives it a new sha256, the approval log no longer covers it,
+     and `/trekexecute` refuses it until the plan is approved again. Say that before the edit.
+   - Never stamp, log or commit an approval in this loop. Only the person's explicit answer approves.
+5. **Fix and Change: edit the text the note points at, and only that.** The quote marks the place.
+   If the comment cannot be done without touching other text (a summary that now disagrees, the same
+   gap in another step, a new criterion the change seems to need), do not edit that text. List it in
+   the reply as a question with a recommended answer. A validator error that was already there before
+   the notes is reported, not fixed in passing.
+6. **Question: answer it in the reply. The text stays as it was.** No new row under alternatives, no
+   new rule, no rewording to "make the answer visible". End the answer with one line offering to write
+   it in if the person wants that. Only their yes turns a Question into a change.
+7. **Build the page again** on the revised file, and print the new link, so the person reads the
+   revised text where they wrote the notes. The page keeps notes per file path, so last round's notes
+   still show in its sidebar: tell the person that "Clear all" empties it before the next round.
+8. **Reply note by note:** for each number, "edited" (with the new wording) or "answered" (with the
+   answer); then the approval consequence from step 4, the open questions from step 5, and the link.
+
+## Red flags
+
+| Thought | What it means |
+|---|---|
+| "I'll add a few points of my own next to the link, to help" | The notes are the person's. Your points steer theirs. Offer a review instead. |
+| "The Question shows a gap, so I'll fix the gap too" | Answer it. The gap is theirs to turn into a Change. |
+| "I'll record the answer under alternatives, so it isn't lost" | That is an edit nobody asked for, and on an approved plan it costs the approval. |
+| "The same fix applies to steps 2 to 4 as well" | Then ask. The note named one step. |
+| "The summary no longer matches the new intent, I'll update it" | Ask, with a recommended answer. The person approves the words. |
+| "The brief fails the validator anyway, I'll fix the frontmatter while I'm here" | Report it. A fix in passing is still a change the person did not ask for. |
+| "I'll mention the approval is stale at the end" | Say it before the edit. It is the price of the edit. |
+| "I'll re-stamp it so planning can go on" | Only the person's explicit approval stamps. |
+
+## Enforced by
+
+- `tests/lib/doc-consistency.test.mjs` and `tests/lib/skills-annotating-prose-pins.test.mjs` (in
+  `npm test`): the script `scripts/annotate.mjs` exists, the three producing commands call it, print
+  the `file://` link and the `open` line, and name this skill. Deterministic, but only at test time.
+- `lib/validators/intent-approval.mjs` (inside `/trekplan`): an edit to `## Intent` or `## Goal`
+  after approval makes the approval stale, and planning halts until the new text is approved.
+- `lib/util/approval-log.mjs` (inside `/trekexecute`, K2): a plan whose current sha256 the approval
+  log does not cover is refused. Both checks hold whether or not the edit's cost was said.
+- prose only: that the person writes every note and Claude none, that a Question changes nothing,
+  that only what the notes ask for is edited, that the cost of the edit is said before it, and that
+  the page is built again.
+
+## Credits
+
+Voyage's own content: the page (`scripts/annotate.mjs`), the loop and its rules come from Voyage's
+pipeline and from the red baseline run for this skill. Nothing here is borrowed.
