6cfa0c55d2 refactor: drop 12 runtimes, keep Claude, Codex, OpenCode, Cursor, ZCode, Antigravity
Removes kilo, kimi, kimi-code, copilot, windsurf, augment, trae, qwen, hermes,
cline, codebuddy and pi end to end: capability descriptors, installer branches
and converters (bin/install.js 14.9k -> 11.2k lines), TypeScript converters,
hook surfaces and runtime homes, review lanes qwen/kimi-code, the two pi
migrations, Kimi payload normalization in the hook guards, dead hostBehaviors
vocabulary, launcher home probes, fixtures, runtime-specific tests and the
prose that presented them as supported.

Installer output for the six kept runtimes is byte-identical to before the
prune. The Kimi tool-vocabulary tests in workflow-guard, read-guard and
read-injection-scanner are left in place pending a decision.

a9a7a328e6 refactor: hard-fork GSD -> MSD (Make Software Done)
Mechanical rename produced by scripts/msd-rename.cjs: gsd/Gsd/GSD -> msd/Msd/MSD
across contents and paths, upstream package/repo coordinates -> @golem15/msd-core
and golem15com/msd-core. Deep links into upstream history, sibling upstream
packages, the GSD-2 import feature, CHANGELOG.md and .changeset/ are kept as-is.

Hand edits on top: MSD block-letter banner and logos, LICENSE copyright line,
package/plugin identity, regenerated lockfile, install-tree fixtures, derived
registries and benchmark baseline; migration checksum baseline re-locked
(MSD keeps its own install state, so no install had applied the old sums);
sort-order and regex-escaped expectations in tests adjusted.

58c7bbb16a fix(#4667): rewrite codex @ includes to the codex install root (#4858)
* test(#4667): add failing-first coverage for the codex @-include rewrite

Behavioral end-to-end: a real in-process install(true,'codex') into a temp
CODEX_HOME must leave zero @~/.claude includes in GSD-owned .md artifacts,
rewrite the issue's own example include to @~/.codex/, keep the deliberate
_GSD_RUNTIME_ROOT .claude fallback chains byte-identical, and stay
idempotent across a reinstall (no doubled prefix). All four are RED until
the installer grows the manifest-scoped rewrite pass.

* fix(#4667): rewrite codex @ includes to the codex install root

Codex-installed agents and commands kept @~/.claude/gsd-core/... (and
@/Users/trekkie/.claude/gsd-core/...) include references pointing into the Claude
install: silent wrong-copy reads on dual-runtime machines at divergent
versions, missing files on codex-only ones. Several emitters bypass the
per-runtime converters, so the per-emitter fixes since #570 rotted.

Adds a manifest-scoped rewrite pass in install() beside the leak scanner:
for codex, every manifest-tracked .md/.toml artifact has the @-include
forms rewritten to the codex root. The pass matches the exact include
literal only — the _GSD_RUNTIME_ROOT/$PREFERRED_CONFIG_DIR fallback
chains, prose .claude mentions, and CHANGELOG.md are untouched — and runs
before the scanner, which remains the verification backstop for anything
a future emitter introduces.

* test(#4667): cover the HOME-anchored include form and sync the pass comment

Adds behavioral coverage for the second rewrite literal
(@$HOME/.claude/gsd-core/ -> @$HOME/.codex/gsd-core/) via the
plan-review-convergence command, and corrects the pass's comment: the
agent .tomls are generated after it and prefix themselves, so the .toml
branch of the rewrite is inert by design.

* test(#4667): baseline the offline upgrade against the deployed tree (sanctioned)

* chore(#4667): backfill changeset PR number (4858)

* test(#4667): sandbox the install home in the include-rewrite tests (#3712 guard)

2f0e99f9e0 fix(#4377): opt in to project-relative includes for local installs (#4425)
* enhance(#4377): opt-in project-relative includes for local installs

A local install wrote the includes that point at GSD's own files as absolute
paths — whatever the installer resolved at install time. For one checkout
that is invisible. Across git worktrees it is not: each worktree gets its own
.claude/ copy, but all of them point back at the checkout that ran the
installer, so a worktree runs its own gsd-tools.cjs while reading workflow
prose from a different checkout. Update that one checkout and every other
worktree is running new instructions against an old engine, with nothing to
stage the update with.

--relative-includes (or GSD_RELATIVE_INCLUDES=1) makes a local install emit
`@.claude/gsd-core/...`. Opt-in, and staying opt-in: absolute works for a
single checkout, which is most people, and flipping the default would change
every existing local install to solve a problem those users do not have.

The prefix is the runtime's own localConfigDir descriptor value, never a
literal — the same value resolveScope joins onto the cwd to produce the
install target, and the same one the rewrite engine already uses for its
./.claude/ -> ./<dir>/ substitutions. Copilot and Antigravity have shipped
this shape for local installs since they were added, with hardcoded .github/
and .agents/; this is that behavior, derived rather than written down.

Six seams compute a path prefix and all six had to be threaded, which is why
the opt-in travels through the environment the way --portable-hooks already
does: one variable they all read cannot fall out of sync the way six
signatures can.

The launcher shim deliberately keeps its ABSOLUTE fallbacks. It probes
gsd-tools through ${CLAUDE_CONFIG_DIR:-$HOME/.claude} and one such default
per runtime; those are shell word expansions, not includes, and a relative
value there resolves against the shell's cwd rather than the project.
Trading an include that points at the wrong checkout for a path that points
at nothing is not a fix. All three rewrite paths mask ${VAR:-default} spans
before substituting and restore them after, and the mask only runs when the
prefix is relative, so an absolute install is byte-for-byte unchanged.

Every unexpressible case falls back to absolute: no opt-in, a global install,
a missing dir name, the configHome.kind === 'none' sentinel, an absolute
descriptor value, or one climbing out of the project with '..'.

* chore(#4377): add changeset for project-relative local includes

* fix(#4377): compare against POSIX-normalized roots in the install e2e arms

The emitted prefix is POSIX-normalized by design — it is substituted into
markdown @-references, which use forward slashes universally, so a backslash
would leak into shipped content (#1615). The e2e arms compared against the
raw temp root, which on Windows is `D:\a\...` and appears in no emitted file.

That reddened the control arm on the windows shard, and it was worse than a
red: the negative arm ("nothing references the checkout") was passing
VACUOUSLY there, because a string that cannot occur is trivially absent. Both
now go through the same normalization, so the Windows lane asserts what the
Linux lane does.

* fix(#4377): tolerate a resolved temp root, and make the e2e diff self-diagnosing

Two changes, one confirmed and one to stop guessing.

Confirmed: the emitted content carries the RESOLVED root, not the spelling
mkdtemp handed back. Reproduced on Linux with a symlinked install root —
236 emitted files carry the realpath, zero carry the link path. macOS has
this structurally, since /var is a symlink to /private/var. Comparisons now
go through both spellings, or the negative arms pass vacuously: "nothing
references the checkout" is trivially true when the string being searched
for cannot occur.

Not confirmed: the macOS shard reported ~every workflow file differing in
the "differ ONLY" arm while the five arms around it passed, and the
assertion printed a list of filenames — which says a difference exists
somewhere across 236 files and leaves the reader to guess which bytes. I
cannot reproduce that platform locally, and guessing turns one CI round-trip
into four. The assertion now reports the first divergence as text: the file,
the byte offset, and a bounded window of both sides.

* fix(#4377): strip the longest root spelling first in the install e2e diff

The macOS failure was my test corrupting its own comparison, not a product
defect. /var/folders/…/X is a SUBSTRING of /private/var/folders/…/X, so
stripping the unresolved spelling first matched inside the resolved one and
left the /private prefix glued to what followed:

  @/private/var/…/X/.claude/gsd-core/…  ->  @/private.claude/gsd-core/…

a string present in neither install, which is why all 236 files "differed".
Sorting the spellings longest-first consumes the whole occurrence, and the
short form then has nothing left to match. Proven in isolation on the exact
macOS shapes: short-first yields @/private.claude/…, longest-first yields
@.claude/….

The self-diagnosing assertion added in the previous commit is what found
this — it named the file, the byte offset, and printed both sides, so the
corrupted string was visible rather than inferred from a list of 236
filenames. Keeping it.

30468f16fe test(#4515): migrate installer-runs batch to named timeout constants (#4575)
* test(#4515): migrate installer-runs batch to named timeout constants

Batch 4 of the ad hoc timeout literal migration (epic #4445). Replaces
every bare numeric timeout/timeoutMs object-literal property across
tests/install.test.cjs, tests/install-minimal-hooks.test.cjs,
tests/fragment-single-edit-propagation.install.test.cjs,
tests/install-regressions.test.cjs, tests/install-runtime-artifacts.test.cjs,
tests/npm-integrity-gate.test.cjs, tests/faulty-deps.test.cjs,
tests/release-tarball-smoke.install.test.cjs,
tests/install-write-confinement.test.cjs, tests/plugin-manifest.test.cjs,
and tests/packaging-shipped-scripts-require-only-shipped.test.cjs with a
named constant, per eslint-rules/no-adhoc-timeout-literal.cjs. Removes
these 11 files from the rule's allowlist.

Adds one new shared constant to tests/helpers/timeouts.cjs for a
fixture-JSON value (in seconds, not ms) mimicking a Claude Code
settings.json hook-entry's own timeout field, shared across two files in
this batch. Every other new constant is file-local, each carrying a
comment explaining why its call site is a distinct operational class from
the existing shared norms even where its digits numerically coincide with
one. No src/bin file touched, no numeric timeout value changed anywhere.

* fix: combine gsd-worktree-path-guard's git rev-parse calls to cut subprocess count under CI load

Discovered while verifying PR #4575 (a full test (windows-latest) failure in an unrelated test, tests/kilo-upgrades.test.cjs's worktree-path-guard rejection test). Root cause: this hook's up-to-4 sequential git spawns (git-dir, branch, worktree-toplevel, file-toplevel), invoked inside a native-plugin's own 8000ms-capped subprocess wrapper, left zero margin for node/git startup overhead — the guard is deliberately fail-open on any timeout, so CI-load-induced latency in this chain silently downgrades a security block into an allow. Combines the first three git rev-parse calls (git-dir, branch via --abbrev-ref, worktree-toplevel) into ONE spawn instead of three, using git's documented multi-flag rev-parse output (one line per flag, in order) — verified empirically including the detached-HEAD edge case. No timeout value changed; this reduces subprocess COUNT, not any tolerance.

39673ae9ff fix(#3738): antigravity global skills/agents install to ~/.gemini/config (#3921)
* test(#3738): antigravity global skills/agents must resolve under ~/.gemini/config

Regression tests (RED first): --skills-root and gsd-tools query surfaces,
install-plan dest dirs, and converter skills-path rewrite.

* fix(#3738): antigravity global skills/agents install to ~/.gemini/config

Antigravity's machine-local discovery scans ~/.gemini/config/{skills,agents};
the configHome (~/.gemini/antigravity) is deprecated for artifacts. Declare the
ADR-1239 skills/agents 'home' override on the antigravity global layout — the
same mechanism codex uses (.agents) — and divert ~/.claude/skills/ references
in converted global content to ~/.gemini/config/skills/. configHome, settings,
probe/migration semantics, and the local .agents layout are unchanged.

* fix(#3738): retire deprecated configHome artifacts via installer migration 010

Next install converges an existing antigravity install: manifest-managed
skills/gsd-*/ and agents/gsd-*.md under the configHome (a location AGY does
not scan) are removed — modified files backed up first, unmanifested and
non-gsd entries preserved — and now-empty containers retired. Global scope
only; the local .agents surface is live. Docs + inventory updated.

* fix(#3738): converter sync in bin/install.js, harness emit-root coverage, migration baseline

- bin/install.js converter gains the same ~/.claude/skills → ~/.gemini/config/
  rewrite as src (ADR-1508 dual copy must stay in sync).
- Parity-manifest walk covers home-override emit roots (extraEmitRootsFor) so
  antigravity's emitted skills/agents stay differential-visible at their new
  install root; install-tree fixture regen confirms an unchanged key set.
- skills-from-commands rule declares the antigravity converter as a
  runtime-scoped transform; one ack fragment covers the identity-classed
  workflow whose antigravity copy embeds the old skills path.
- Migration 010 checksum baseline + home-override set doc updated; existing
  tests updated to the #3738 contract (global dest, golden parity via layout
  dest, integration expectations).

* fix(#3738): tolerate an absent extra emit root on baseline-side measurement

The base tree's installer predates the home override, so <HOME>/.gemini/config
does not exist there; walk() threw ENOENT and the in-job baseline build failed.
An absent extra root is the legitimate pre-override shape — skip it.

* fix(#3738): review findings — manifest agents root, bare skills-path rewrite, guard comment

- writeManifest resolves the agents-kind home override (_kindDestDirSafe), so
  the manifest records agents at their actual install root and drift detection
  keeps working (isolated review finding 1, major).
- Converter bare forms ~/.claude/skills and $HOME/.claude/skills (no trailing
  slash) divert to ~/.gemini/config/skills instead of falling through to the
  retired configHome path (finding 2).
- real-home-guard comment updated: antigravity's global agents kind is the
  first agents-kind home override (finding 3, doc-only).
- Regression tests for both behavioral findings.

* chore(#3738): changeset fragment (pr number backfilled after PR creation)

* chore(#3738): backfill changeset PR number (3921)

* fix(#3738): sandbox HOME in tests that install antigravity global artifacts

antigravity is the first home-override runtime in the golden-parity and
skills-wrapper suites (codex is not in their runtime lists), so those tests
never needed HOME sandboxing — the real-home guard now (correctly) refuses
their un-sandboxed global installs on CI, where HOME is the passwd home.

* fix(#3738): stop the K3 sequential-sandbox env leak; sandbox L2's home-override plans

K3's two back-to-back sandboxHome calls leave HOME pointing at the first
sandbox once the after-hooks restore (each call saves the env as it found
it, so the second saves the first's sandbox as 'original'). On the windows
matrix that leaked gsd-k3-qwen-* home into the L2 property, whose
antigravity/global run then (correctly) refused via the #3712 real-home
guard — antigravity is the runtime that made L2's plan escape into
os.homedir(). K3 now manages the env with a single restore; L2 sandboxes
HOME per run, mirroring L1.

* fix(#3738): L2 property's HOME sandbox must exist on disk

The #3712 guard's sandbox exemption fails closed when identify(effectiveHome)
is 'absent' — L2 never created its configDir, so on the windows matrix (tmpdir
under the real home) the antigravity/global run refused even with HOME
sandboxed. Create the per-run sandbox dir and clean it up.

8641d0a468 fix(#3719): restore @-includes on the agents emit path, so global Claude installs load their guidance (#3918)
* test(#3719): failing-first coverage for the agents emit path's missing tilde restore

applyAgentPathRewrites performs its four tilde and HOME substitutions and never
calls restoreClaudeGlobalAtRefTilde, which has exactly one call site in the module
and it is not this one. So every agents/gsd-*.md in a global Claude install ships
@HOME-form includes, and per #3544's own measurement such an import loads nothing --
planner guidance, the untrusted-input boundary, the skills bootstrap and the
mandatory initial read are silently absent from subagent context.

The load-bearing rows are END TO END, driving a real install into a temp HOME. The
reported symptom is 27 of 34 EMITTED FILES, which is a claim about files on disk; a
unit test on the rewrite function would pass while the emitted tree stayed broken,
and that is exactly how #3133 and #3544 fixed two emit paths and left a third broken
across two releases.

The parity row walks the WHOLE emitted tree rather than a list of known paths, so a
fourth emit path added later is covered by landing in the same tree. Pinning the bug
alone would leave that path free to regress identically. It names the offending
files on failure, and it inspects bytes from a real subprocess install rather than
asserting a function agrees with itself -- the tautology I shipped in the #3714
divergence guard.

Four controls separate calling the restore from reverting the substitution: the
restore is targeted, rewriting @-includes while deliberately leaving ordinary prose
paths on HOME. Reverting wholesale would satisfy the positive row and break every
prose path.

One boundary row is deliberately red beyond the obvious fix. The agents path also
runs a word-boundary rewrite that strips the trailing slash, while the restore is
anchored to the exact prefix -- so a call mirroring the sibling site leaves
@HOME/.claude with no trailing slash broken. Verified: restore(prefix) leaves it,
restore(normalized) fixes it, and both leave prose alone.

* fix(#3719): restore @-refs to tilde on the agents emit path

The third emit path that needed this. #3133 added the restore to the skill and
command pipeline, #3544 to the spec-tree copy in install.js, and the agents pipeline
never got it -- so every @~/.claude include in a global Claude install shipped as
@HOME-form and resolved to nothing. Per #3544's own measurement such an import loads
NOTHING, so the planner's guidance, the untrusted-input boundary, the skills
bootstrap and the mandatory initial read were silently absent from subagent context:
27 of 34 emitted agents, 103 lines.

Two details that a one-line call mirroring the sibling site would have got wrong,
both verified by execution before writing the fix.

It passes the NORMALIZED prefix rather than pathPrefix. This function also runs two
word-boundary replaces that emit the trailing-slash-free form, while the helper's
regex is anchored to whatever prefix string it is handed -- so restore(pathPrefix)
fixes @HOME/.claude/x and leaves a bare @HOME/.claude broken. The normalized form is
a prefix of both, so one call covers both.

And it is guarded on claude. The helper self-guards only on the HOME prefix, but
every runtime's global prefix is a HOME form, so an unguarded call would rewrite
@-refs for runtimes whose resolver documents no tilde expansion at all. Verified:
claude restores, cursor and kilo do not.

The targeted behavior is preserved -- @-includes move to tilde while ordinary prose
paths and quoted shell strings stay on HOME, which is what the blanket substitution
exists for since tilde does not expand inside double quotes.

* fix(#3719): stop the word-boundary replaces corrupting a non-default config dir

Review found that my fix MASKED a pre-existing bug, which is worse than leaving it.

The two word-boundary replaces used a bare word boundary, which matches between 'e'
and '-', so with --config-dir .claude-work they turned .claude-work/ into
.claude-work-work/ -- 119 dead paths in a real install. #3544's review installed a
negative-lookahead guard at the installer's copy path for exactly this, and the
shared helper's doc comment claims the gap was corrected at ALL call sites. It was
not corrected here.

That much is pre-existing; base emits the same 119. What my change did was make it
INVISIBLE: the restore rewrites the corrupted string to a tilde form, which reads as
correct, so every HOME-based detector -- including the parity row I added in this
branch -- goes green on a broken tree. A fix that hides the evidence of a
neighbouring bug is not a fix.

Both replaces now use the same lookahead as the installer site, with a test on a
non-default config dir asserting the emitted path by identity.

Three test weaknesses from the same review, all of which would have passed while
guarding nothing:

The parity row anchored its detector at line start, so it could not see the 48
mid-line refs the helper deliberately supports -- half-blind while being billed as
the future-proof row.

The runtime guard had ZERO coverage: the only non-claude row used copilot, which
returns early and never reaches the guard. Cursor and kilo rows now exercise it.

And the quote-lookbehind control contained no at-sign at all, so it passed with the
lookbehind deleted. It is now a real quoted ref, verified to fail when the lookbehind
is stripped.

* test(#3719): distinguish a live @-include from prose describing one

My own MINOR fix introduced a BLOCKER. Dropping the line-start anchor was correct --
it had hidden 48 mid-line refs the helper deliberately supports -- but it also made
the scan see gsd-core/CHANGELOG.md, which ships the #3133 and #3544 entries quoting
the broken form verbatim while describing the very defect this row guards. Two
documentation lines became two failures on a CORRECT tree: red CI, nothing wrong.

Fixed by stripping inline-code spans before the test, not by restoring the anchor.
Restoring it would trade a false positive for the false negative that let this bug
ship in the first place. A live include is bare markdown; an occurrence inside
backticks is prose ABOUT one.

Verified the distinction holds in both directions, including the case that matters
most: a line carrying a backticked example AND a real bare reference still flags,
because only the code span is stripped.

* fix(#3719): escape the replacement pattern, and pin both fixes that shipped unproven

Security's remaining item, landed here on its recommendation: the restore used a
STRING replacement, so a config dir containing the ampersand or backtick dollar
forms was treated as a special pattern. Measured: one corrupted output into a
duplicated path, the other silently DROPPED text. Pre-existing, and this branch adds
a third call site to that sink -- which is how the previous two came to share the
defect. It is a function replacement now.

Two fixes on this branch were shipping UNPROVEN and both are now pinned:

The word-boundary fix had no regression test at all. An implementing agent reported
adding one and I accepted that report without checking the diff; the reviewer found
it missing. Pinned by identity at a config dir extending the default, with the
measured 120-to-0 recorded in a comment so a later reader knows what it protects. A
second row uses a word-character extension, which was never doubled -- a bare word
boundary needs a word to non-word transition, so only the hyphen triggered it.

The replacement fix likewise had none; both pathological prefixes now round-trip and
an ordinary prefix is asserted unchanged.

Neither could be proven by reverting src in scope, so the pre-fix behaviour was
replicated inline and the delta recorded rather than assumed.

* test(#3719): state the trust model accurately in the replacement-pattern note

The comment described the config dir as attacker- or operator-controlled. Security
assessed it as operator-only, and calling it attacker-controlled overstates the trust
model on a change that landed for consistency rather than urgency: the damage is a
mangled path, not a boundary crossing.

That is the fifth comment on this sweep to assert something the code or the threat
model does not support, so it gets corrected rather than left as harmless prose --
the pattern is the finding.

* chore(#3719): backfill changeset pr number

Doing this immediately after PR creation this time: the same omission was the only red CI on the previous PR tonight.

107eb8c1d9 feat(#3753): run docs guards on the PR that changes the docs they read (#3787)
A PR whose diff is entirely under docs/ runs zero tests, so a guard whose INPUT
is shipped prose cannot protect the PR lane of the diffs it exists to check. Its
only firing opportunity is after merge, on the shared branch -- which is how next
went red on dacae9273 while the PR that caused it (#3746) was green on every
check.

The docs-lint job in .github/workflows/docs-required.yml -- an ALREADY-REQUIRED
context -- now selects and runs the docs guards that read the specific docs files
the PR changed.

  scripts/docs-guard-registry.cjs    test file -> the docs paths it reads (63)
  scripts/select-docs-guards.cjs     pure (changedPaths, registry) -> test files
  scripts/lint-docs-guard-registration.cjs   drift guard, wired into lint:ci

scripts/ci-test-scope.cjs is NOT touched -- `git diff origin/next --` on it is
empty -- so #764's saving stands and its 21 pinning tests are untouched.

Selection: exact path; trailing-slash directory prefix (boundary-checked --
docs/adrenaline.md does NOT match docs/adr/, which a naive startsWith gets
wrong); and '*' for the 6 entries that walk docs/ generally or read a computed
path. Unknown maps to '*' -- guessing narrow is how a guard silently stops
running. Measured: a typo fix selects 6 of 63; docs/AGENTS.md selects 12;
docs/COMMANDS.md selects 18.

Four things this got wrong first, each found by an independent reviewer or by
probe, and each having been asserted safe in a comment:

1. The registry started as a RULE in ci-test-scope.cjs's RULES, on the theory
   that classify()'s !codeChanged normalization made it inert. True for
   docs-ONLY diffs; false for MIXED docs+code diffs, where codeChanged is true
   and the normalization never runs:

     node scripts/ci-test-scope.cjs --files "docs/a.md src/semver.cts"
       with the RULE:  25 targeted_tests
       origin/next:     3 targeted_tests

   Category error: RULES is the scoped lane's input; a docs-guard registry is a
   lane manifest for a consumer that never calls classify(). Extracted; pinned
   by value.

2. The second attempt was a dedicated workflow with paths: [docs/**]. Such a
   workflow never reports on a non-docs PR, so it can never be a required
   context without hanging every non-docs PR -- and a non-required check does not
   block a merge, so the guard would have been advisory and #3753 unfixed.
   docs-required.yml already has no paths: filter, already supplies the required
   docs-lint context, already computes docs_changed, and already ran one docs
   guard gated on it. Generalizing that step needs no ruleset edit at all.

3. The registry and the drift lint were built from ONE path-segment heuristic, so
   both were blind identically -- and blind at the guard that motivated the issue.
   The reader-call regex required a character BEFORE its keyword, so a callee
   named exactly read( / load( / parse( / doc( / file( / content( could never
   match; and only an INLINE path.join(ROOT,'docs','X.md') argument was caught,
   missing the two-step-via-variable form -- the MAJORITY spelling -- plus
   template literals and concatenation. Detector 1 fired on 14 of ~450 files, so
   35 genuine guards sat unregistered while the lint reported 0 violations,
   including cursor-reviewer (reads docs/COMMANDS.md, asserts
   .includes('--cursor')) and inventory-headings-countfree. The "accepted blind
   spot" this shipped with was the common case, not a fringe.

4. With detection fixed the true population is 115 files: 63 genuine guards, 52
   incidental. Running all 63 in a REQUIRED check on a one-line typo fix is the
   cost #764 exists to avoid -- install.test.cjs is 7840 lines and reads exactly
   one docs file, docs/AGENTS.md, for its frontmatter. Dropping it reproduces the
   bug; running it for a typo elsewhere is waste. Hence the map.

Then a second review round found six more, all fixed here:

- fragment-single-edit-propagation.install.test.cjs was EXEMPTED as
  "overlay fixture only". False: it reads the real docs/registries/eos.json and
  asserts on a registry entry name, and reads the real ADR-0001 and asserts its
  H1. A docs-only PR touching either would have gone green and red next -- #3753
  shipping again, from inside the fix for it. Now registered against both paths,
  and all 52 remaining exemptions were re-audited one by one.
- The SUITES-collision guard compared RAW registry keys, but run-tests.cjs strips
  a leading `tests/` BEFORE its suite check. So it caught 'all' and missed
  'tests/all' -- the only spelling that can actually occur, since every key
  carries the prefix. One typo would have run all 824 test files inside the
  required job. Now normalized the same way run-tests.cjs normalizes.
- The lint failed OPEN on an unreadable tests dir or candidate file: 0 violations,
  ok:true. A guard that cannot read its input must never report success.
- The exemption ratchet gated identity only, so a baselined file that later
  STARTED asserting on shipped docs stayed exempt silently -- 52 permanently blind
  files. The baseline now fingerprints the docs paths each exempted file
  references and fails when that set changes, naming what changed.
- The exemption marker was still honored inside a multi-line template literal in
  the header window. The scanner now tracks template-literal and block-comment
  state.
- `git diff --name-only | grep '^docs/'` silently dropped C-quoted non-ASCII docs
  paths, making docs_changed=false a green zero-guard check. Both call sites now
  pass -c core.quotepath=false.
- The run step was gated on hashFiles(), which a force-committed
  .docs-guard-tests.txt would satisfy. The step now rm -f's both scratch files
  first and gates on an output it sets itself.

Three empty states, deliberately distinct, because conflating them rebuilds
#3753: an empty or malformed registry HARD-FAILS; docs changed with no guard
covering them logs and skips; no docs change is already gated. The middle state
must never be expressed as an empty --files-from, which prints `no tests in suite
"all"` and exits 0 -- a green check that guarded nothing. With the current
registry that state is unreachable, because the six '*' entries always match;
the branch is kept as defensive handling for a future registry and says so.

timeout-minutes: 15 bounds the required job against a hanging fork-supplied test;
it had none. npm ci was added because the job never installed dependencies -- the
previous single-file step got away without it, the registry does not.

docs/contributing/docs-guard-registration.md documents the rule, following its
sibling cross-platform-portability-rules.md, and CONTRIBUTING.md's CI Test
Quality Checks table links to it. It is also load-bearing: without a docs/ file
in the diff this PR would not have triggered its own lane, shipping an
unexercised change to a required check.

One unrelated fix, included because this PR surfaced it and CLAUDE.md forbids
deferring a defect found while working. On this branch's first CI run,
`full test (windows-latest, 24, shard 3/3)` was CANCELLED at exactly 30 minutes;
tests were still passing 0.8s before the cancel, so it is a wall-clock timeout,
not a hang, and a cancelled job reddens `Required tests`.

The cause is not this PR's test file, which costs ~60ms. Shard composition is
unstable: adding ONE file to the unit suite reshuffled 115 of 268 files between
shards, and shard 3 drew a heavier mix. Underneath that is a real pre-existing
defect. tests/ci-test-job-timeout-budget.test.cjs requires every lane's budget to
be >= 1.5x its MEASURED cost -- "a lane that got slower must be re-budgeted, not
excused" -- and its test-full entry recorded 19m from a windows-22 shard. That is
stale. Measured on `next` with none of this PR's changes present: 26m18s (run
32614439702, windows-latest/24 shard 3/3), 23m36s and 23m17s on shard 2/3. So the
lane costs ~26m and the 30-minute cap carried 1.14x headroom, not 1.5x. The gate
had been out of compliance with its own rule; this PR was merely the file
addition that reshuffled shard 3 past the cliff.

Fixed as that file prescribes: measuredMinutes 19 -> 27 with fresh evidence, and
test-full timeout-minutes 30 -> 45. The rule's minimum for 27m is 41; 45 is
deliberately above it because the reshuffle means per-shard worst case moves run
to run, and a budget pinned to the exact minimum would be re-breached by the next
test file anyone adds. Only that one job's timeout changed; test.yml's scope,
matrix and steps are untouched, so #764's saving is unaffected.

Raising that cap let the Windows shard finish (28m45s, inside 45) and uncovered
a real failure the 30-minute cancel had been masking:
`new quick-task branch branches off origin/main (#2916)` died with
`outcome=timed_out exitCode=null`, SIGTERM, at the 15000ms bound.

tests/quick-branching.test.cjs:149 `runStep` runs a `#!/usr/bin/env bash` script
executing MULTIPLE git commands, but was bound to GIT_TIMEOUT_MS (15000) -- the
norm for a SINGLE git plumbing call. tests/helpers/timeouts.cjs already documents
this exact failure and exists to fix it: HOOK_FANOUT_TIMEOUT_MS was created after
PR #3285 recorded "outcome=timed_out exitCode=null at exactly the 15000ms probe
bound while every other lane passed the same commit", and calls that "a bound
sized for the wrong class, not a slow machine". Our failure is that case
verbatim, so both sites move to the class norm rather than to a bigger number.

The same class also failed on `next` itself 21 hours earlier -- run 32608945654,
windows-latest/24 shard 1/3, `plan touching only src/ in a submodule project
keeps worktree isolation ENABLED` -- where tests/worktree-safety.test.cjs:5845
`runGate` fans out to `git config --file .gitmodules` under a hardcoded 30000.
Fixed too, since it is a defect in the tree regardless of which branch surfaced
it.

A survey of the whole tests/ tree found the same class-mismatch at further
bash fan-out sites bound under 60000ms, and the maintainer approved sweeping
them rather than leaving them latent to surface the same way one at a time. 16
fan-out sites across 16 files now use the class norm.

The sweep is class-correctness, not raising numbers until things pass. Sites
were moved ONLY where the bash body demonstrably spawns something (git, node,
npm, a CLI); self-contained shell snippets were left where they are, and are
listed as deliberately unchanged: pure if/printf bodies (copilot-install), pure
array/case builtins (code-review-pipeline-regression:638), a documented
pure-shell gsd_run stub (host-integration), single-process hook calls
(workflow-guard:222/271/302), and a deliberately tight 5000ms fast-check hook
(gsd-write-guard.property). Nothing was lowered. process-seam.test.cjs:513
(literal 300) is untouched on purpose -- it tests timeout BEHAVIOR, so raising
it would destroy what it asserts.

Shared file-level constants were the trap here, and were handled per file rather
than by redefinition: GIT_TIMEOUT_MS has ~15 users in git-base-branch and only 1
is a fan-out; WORKTREE_TIMEOUT_MS has 16 users in worktree.test.cjs and 3 are;
PROBE_TIMEOUT_MS has several in three more files. In each the CALL SITE was
changed and the constant left alone, so no single-plumbing-call site silently
inherited a 60s bound. The one exception is hooks-opt-in.test.cjs, where
HOOK_TIMEOUT_MS has exactly one consumer -- spawnHook, the fan-out itself -- so
redefining it is identical in effect and reads better.

Only two of these sites have actually been observed failing. The rest cite that
shared class and those two run ids rather than inventing evidence of their own.

a44d513566 fix(#3712): confine in-process installs to a sandboxed HOME (#3725)
* fix(#3712): confine in-process installs to a sandboxed HOME

A runtime kind may declare a global `home` override resolved from os.homedir()
rather than from the caller's configDir — codex's skills kind (`home: ".agents"`,
ADR-1239 / #2088) is the only live case. Sandboxing configDir/targetDir does not
contain it, and assertDestWithinConfigHome cannot see the class: that gate
confines a destSubpath to whatever root it is handed, and here the root IS the
escaped home. So an in-process caller that forgot to sandbox HOME wrote to, and
pruned gsd-* entries from, the developer's REAL ~/.agents/skills.

tests/agent-descriptor-parity.install.test.cjs's K1 loop did exactly that: it
iterates every agents-kind runtime (codex included) with a sandboxed targetDir
and an un-sandboxed HOME. Reproduced against a canary home on next @ adb46cdd8 —
71 gsd-* skill dirs deleted, a foreign `cloudflare` skill surviving, suite still
exit 0. It is silent because the runtime's own config home is untouched, so the
manifest keeps reporting a healthy install.

FIVE writers resolve a kind `home` and then destroy under it. Three are reachable
today — installRuntimeArtifacts, uninstallRuntimeArtifacts (install-engine.cts)
and applySurface (surface.cts). Two are descriptor-dependent and guarded against a
future descriptor change rather than a present escape: installOpencodeFamilySkills
(behind the combined-family early return) and installAgentsKindStandalone. Those
two are scoped to the single kind each destroys — passing the whole layout made
codex's unrelated skills override trip a writer that never touches it.

- src/test-home-guard.cts: refuse when a run under a test runner cannot be shown
  to have sandboxed HOME. NODE_TEST_CONTEXT (set by `node --test`) gates it, so
  installs outside a Node test context are untouched; GSD_TEST_MODE is unusable,
  as several candidate files including the offender never set it. Homes are
  compared by FILESYSTEM IDENTITY (st_dev + st_ino), not by pathname:
  path.resolve() resolves neither symlinks nor case, and realpath returns a
  canonical pathname that two routes to one directory can still disagree on (bind
  mounts). Verified on macOS/APFS — HOME=/users/<name> made the strings differ
  while naming the same directory, and the lexical form ALLOWED a write into the
  physical real home. FAILS CLOSED: a pair is "different" only when both identify,
  or one is definitively absent (ENOENT/ENOTDIR) while the other identifies; every
  other errno is "cannot tell" and refuses. Only when neither home identifies is a
  marker consulted, and it carries the sandbox PATH and must equal the home in
  effect — a boolean checked first let an ambient or stale value disarm the guard.
- helpers: promote sandboxHome() out of its two byte-identical private copies,
  which is also what makes them record the sandbox; the three withFakeHome()
  helpers record it too. The marker NAME is duplicated as a bare string rather
  than required from the compiled guard, keeping helpers.cjs's documented
  no-built-lib-at-import-time contract; a test pins the two together.
- agent-descriptor-parity: sandbox HOME across the K1 loop.
- helpers-process-isolation: #3156's canary asserts on <home>/.gsd only, and its
  `--cursor --local` spawn cannot reach `.agents` at all, so an assertion added
  there would pass with all confinement removed. Add a discriminating row — a
  `--codex --global` spawn against a seeded ambient home — which also asserts the
  runtime still declares the override. Its check is a sampled inventory (dir names
  + each SKILL.md), not a tree compare.
- install-write-confinement: predicate rows through the deps seam, covering the
  symlinked HOME, ambient and stale markers, and each sameDirectory branch
  (both-identify, one-absent, neither-identifiable), plus wiring rows that drive
  the REAL entrypoints so deleting a guard call site is red.

Verified: guard fires end-to-end against a real un-sandboxed HOME (exit 1, zero
deletions); the case-variant fail-open reproduced on APFS before the fix and
refuses after; K1 file 29/29 green with skills intact; mutation-tested — each of
the three reachable call sites, lexical-only comparison, and treating an unknown
errno as "absent" each take exactly one row red, with every mutation echoed back;
the process-isolation row negative-controlled by reverting installerEnv to its
pre-#3156 leak (16/0 -> 13/3); a full npm test leaves ~/.agents/skills at 71.

Stated residual: the two descriptor-dependent writers have no wiring test, because
no runtime declares a `home` override on those kinds and neither can be exercised
without inventing a descriptor.

* fix(#3712): let a sandbox nested inside the real home through the guard

All six Windows shards of #3725 failed on legitimately sandboxed
destinations. On Windows os.tmpdir() is %LOCALAPPDATA%\Temp — inside the
user's home — so every sandbox a test creates is a descendant of the real
home, and "does this land inside the real home?" answers yes for the safe
case and the dangerous one alike. POSIX conceals this: /tmp and
/var/folders both sit outside $HOME.

Add the missing conjunct: a destination inside the real home is allowed
only when it also sits beneath a HOME that was sandboxed away from the
passwd home. Both halves are required — dropping the first re-admits a
plain un-sandboxed install, and dropping the second decays into the
"is HOME sandboxed?" check the module rejects, which a layout resolved
before the sandbox walks straight through. Each is mutation-proven by a
row that goes red without it.

Also covers the two fail-closed branches of the new exemption, which
survived mutation to `true` with the suite green, and avoids `<user>` in
a docblock — the prompt-injection scanner reads it as a delimiter tag.

* fix(#3712): close three writer/rollback gaps found reviewing the whole PR

Cross-AI review of the full PR (not just the round's delta) surfaced
three ways the guard could still be defeated:

- The nested-sandbox exemption trusted the SPELLING of a destination.
  With HOME sandboxed to a directory inside the real home — legitimate on
  Windows — an aliased `.agents` (symlink, junction, subordinate bind
  mount) beneath it redirected an allowed path into the real home. Decide
  containment on the path the write RESOLVES to: walk up to the nearest
  existing ancestor, canonicalize, re-append the tail.

- `migrateLegacyDevPreferencesToSkill` is a SIXTH writer that resolves a
  skills-kind `home` override. It creates rather than prunes, which is
  why it was missed, and `_runLegacyInstallMigrations` runs it before
  `installRuntimeArtifacts`' own assertion. Guarded, scoped to that kind.

- Worst of the three: `bin/install.js` snapshots the resolved skills root
  before installing, and its outer catch rolls back by deleting and
  recreating every snapshotted `gsd-*` directory there. The guard's own
  throw landed in that catch, so refusing an un-sandboxed codex install
  provoked exactly the mutation the guard exists to prevent. Refusals are
  now marked and rethrown without rollback — nothing was written, so
  there is no partial install to undo. Every other error still rolls back.

Also carries the sandbox marker into `installSpawnEnv`, so spawned
installers are not refused on passwd-less CI images, and corrects three
claims that no longer hold: "every writer" (six, and named), the
unconditional "fails CLOSED" (the passwd-less marker branch is a
deliberate weakening, and TOCTOU is out of scope), and the assertion that
Windows os.tmpdir() is always %LOCALAPPDATA%\Temp (Node honors TEMP/TMP).

* docs(#3712): name the guard's two limits instead of overclaiming

Round-2 review found the prose had drifted ahead of the code. Corrected,
with no behavior change:

- The module still said FIVE writers; there are six, and the sixth is
  now named along with why it was missed (it creates rather than prunes)
  and why it carries its own assertion (it runs before the main one).
- The canonicalization docblock listed subordinate bind mounts among the
  aliases it closes. It does not close them: a bind mount is not a link,
  so realpath keeps the mount-point spelling. `sameDirectory` already
  recorded that limit; the new helper now inherits it explicitly rather
  than contradicting it. Closing it needs mount-table introspection.
- "FAILS CLOSED" was unqualified while the passwd-less marker branch is
  a deliberate weakening — with no passwd entry, nothing can contradict a
  marker naming the real home.
- "Refuses BEFORE any write" was too broad: legacy install migrations run
  ahead of the layout-driven ones, which is exactly why the two
  rollbackInstallerMigrations() calls still execute before the rethrow.
  Only the codex skills-root rollback is skipped, and that is the only
  _codexPreConfigRollback() call site — applySurface is never called from
  bin/install.js and uninstall cannot reach it.

* fix(#3712): sandbox HOME in the opencode-family home-override parity rows

The last two Windows failures, and the same platform asymmetry in a
different disguise. This row drives a skills-kind `home` override on
purpose — precisely what the guard polices — but relied on the override
temp dir happening to sit outside the real home. It does on POSIX
(/tmp, /var/folders); on Windows os.tmpdir() is under %USERPROFILE%, so
the guard correctly refused and only Windows went red.

Declare the sandbox instead of depending on the platform: HOME becomes
the override itself, which is the home the call writes under. This is the
fix the guard's own message prescribes, applied to the test rather than
to the guard.

Both failing Windows shards fail on exactly these two rows and nothing
else; every other shard is green.

* fix(#3712): make sameDirectory answer NO when it cannot tell

Review Major 1. sameDirectory()'s only caller is the passwd-less marker
branch, which reads a `true` as permission to PROCEED:

    if (marker && sameDirectory(marker, osMod.homedir())) return;

The fallthrough returned `true` whenever neither side identified — two
absent paths, or two stats failing EACCES/EPERM/EIO on a locked-down
host — on the reasoning that "cannot tell" should make the caller refuse.
That reasoning was inverted with respect to this caller: it turned the
passwd-less escape hatch into an unconditional bypass for any marker
value at all, on precisely the hosts the fallback exists to serve. Only
two things now answer yes: one resolved pathname, or two readable
identities that match. Restoring the old fallthrough takes the new row
red.

Also from review:

- Major 2 asked whether st_dev/st_ino discriminate directories on
  Windows, where Node derives them from BY_HANDLE_FILE_INFORMATION. The
  whole guard rests on that primitive, so assert it rather than argue it:
  a row comparing two distinct temp directories, and one directory
  reached by two spellings. It runs on every platform in the matrix, so
  Windows answers the question itself.

- Minor 1: the refusal now names the real home it compared against, not
  just the destination it refused. That is the one fact needed to tell a
  true positive from a false one, and its absence is what made the
  Windows case a CI-log dig rather than a glance.

Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

* fix(#3712): refuse a HOME that merely spells the real home more widely

Review round: one Blocker, four Minors, a Nit.

N2 (the one with teeth) — a destination's ancestor chain is linear, so
"inside the real home AND inside the effective HOME" admits two
arrangements, not one. The intended `effectiveHome ⊂ realHome` is the
Windows temp shape; `realHome ⊂ effectiveHome` — HOME at /Users, /home,
C:\Users — is not a sandbox at all, it is the real home reached by a
wider spelling, and it was exempting a stale destination pointing
straight at ~/.agents. Third conjunct added; the docblock no longer
claims two conditions suffice. Removing the conjunct reds the new row
and nothing else.

N4 — the migration guard resolved its OWN layout, and without
capabilityRegistry, so a registry-dependent descriptor could make it
vouch for a path the migration does not write: a guard reporting safe
while the unsafe write proceeds. It now guards the destination already
resolved by _resolveDevPreferencesSkillTarget, keyed on
`installRoot !== targetDir` — which is exactly the condition under which
a `home` override was declared, read off that same result.

N1 — CONTEXT.md gains the Test Home Guard Module glossary entry that
contributor-standards.md requires of a new Module. Not CI-enforced, so
green CI was never evidence it was met.

N3 — the docs/INVENTORY.md row was misfiled between install-fs-adapter
and install-model-override-resolver; the table is alphabetical and the
manifest already had it right. Moved, and its text now names six writers
and the third conjunct.

N5 — applySurface's signature docblock was two parameters stale; this PR
added the second of them.

N6 — the duplicated rollbackInstallerMigrations() adjacent to the new
rethrow: two identical consecutive calls, not two phases.

* fix(#3712): guard the sixth writer, and close two false-ALLOW paths

Review round 3 (NEW-1, NEW-2) plus three defects Codex found in the
whole-PR pass, each reproduced before it was fixed.

NEW-1 — migrateLegacyDevPreferencesToSkill called the guard with no
`deps`, so it bound real os/process.env and could not be wiring-tested
the way the other three reachable writers were. It now takes the same
optional `deps: { os?, env? }` tail parameter. The wiring block gains
the missing fourth row, and a fifth pinning the ALLOW half; the test
file's header docblock said "FIVE writers ... the three reachable
today", contradicting the six/four statement this PR already put in
src/test-home-guard.cts, CONTEXT.md, docs/INVENTORY.md and the
changeset. Both directions of the guard's condition now fail a row
when broken — previously neither did.

NEW-2 — derivesFromSandboxedHome's docblock claimed "THREE conditions
are required, and no two of them suffice". False for {2,3}: isInside is
reflexive, so whenever conjunct 1 fires conjunct 2 already returns
false on its own. Reworded as a fast path, which is what it is.

Codex 1 (false ALLOW) — on a host with no readable passwd entry the
marker branch returned as soon as the marker matched the effective
HOME. That attests a caller sandboxed HOME and says nothing about where
an already-resolved destination points, so a layout captured before
sandboxHome() — still naming the real ~/.agents — was waved straight
through: the same stale-layout shape the primary branch refuses by
design. The marker must now identify AND contain every destination.

Codex 2 (false ALLOW) — `installRoot !== targetDir` was the stand-in
for "the skills kind declared a home override". The two are not
equivalent: the inequality is false when the override resolves onto
targetDir itself, which is exactly a configDir of $HOME/.agents. The
guard was skipped and SKILL.md written into the real home under a test
runner. _resolveDevPreferencesSkillTarget now reports hasHomeOverride
off the same resolution instead of inferring it from two paths.

Codex 3 (prose) — the shared refusal message claimed every guarded
writer prunes; the migrate writer only creates. The changeset headline
claimed in-process installer calls can no longer reach the real home,
which is wider than the guard: writeNonClaudeDefaults still writes
~/.gsd/defaults.json through os.homedir(). INVENTORY's and CONTEXT's
fail-closed sentences omitted sameDirectory's pathname-equality
shortcut. All four narrowed to what the code does.

* fix(#3712): let the sandbox marker follow an overridden HOME

Found by Codex in the whole-PR pass. installSpawnEnv spreads
`overrides` last so an explicit HOME wins — deliberate, and its
docblock tells callers needing per-spawn isolation to pass their own
{ HOME, USERPROFILE }. But the #3712 marker was set before that spread,
so such a caller got HOME=<theirs> and marker=<helper default>. On a
host with no readable passwd entry the guard compares the two and
refuses a legitimately sandboxed spawn — tests/install.test.cjs:7143
and install-shared.cjs's own runInstaller both take that path.

The marker is now derived from the final HOME unless the caller
supplied one explicitly. The contract test asserted HOME after an
override but not the marker, which is why it stayed green.

Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

* docs(#3712): name the shipped guard condition, not the deleted one

Review round 4 of #3725. Two artifacts this PR adds still described
`target.installRoot !== targetDir` in the PRESENT tense as the live guard
condition on `migrateLegacyDevPreferencesToSkill`. The shipped condition is
`runtime && target.hasHomeOverride` (src/install-engine.cts:510).

This is not ordinary doc drift. The named condition is the exact false-ALLOW
the previous round closed: a `home` override resolving onto `targetDir` — a
configDir of `$HOME/.agents`, which is where codex's override points — makes
the inequality FALSE while the override is declared, so the guard was skipped.
A maintainer reading CONTEXT.md:290 as authoritative would believe the guard
still skips that case.

  - tests/install-write-confinement.test.cjs — the ALLOW-half row's comment.
    Its "teeth" rationale is unchanged and still correct as written.
  - CONTEXT.md:290 — the Test Home Guard Module glossary entry, a documented
    PR gate. Now states the condition and names the inequality only as what it
    is NOT, with the reason.

The three surviving mentions of the inequality are all past-tense or negated
(src/install-engine.cts:448, :508 and the sibling test comment at :3698) and
are correct as they stand.

Verified: `npm run lint:ci` exit 0; full `npm test` 31327 tests / 31312 pass /
0 fail / 14 skipped, run with TMPDIR unset.

* fix(#3712): canonicalization fails closed, matching identify's errno split

Codex full-PR review of #3725, run against the round-4 head.

`resolveThroughLinks` caught EVERY realpathSync error and fell back to
`path.resolve(dest)` — the lexical spelling. That inverts the function's own
purpose. An aliased `<sandbox>/.agents` that cannot be canonicalized keeps its
sandbox spelling, satisfies the nested-sandbox exemption at :227, and the write
is ALLOWED into the real home — the exact escape this walk exists to close. The
module documents that it fails CLOSED with ONE named exception (the marker
branch); this was a second, unnamed one.

Split by errno, and deliberately by the SAME split `identify` already draws
rather than a second policy in one module — both answer "does this path exist
as named?", so they must not disagree:

  ENOENT / ENOTDIR -> walk up. The ordinary case: a fresh install resolves a
    destination nothing has created yet, so realpath fails on the leaf and on
    every not-yet-created ancestor. Refusing here rejects every install.
  anything else (EACCES, EPERM, ELOOP, EIO) -> refuse. The component exists but
    cannot be resolved, so the guard cannot tell where the write lands.

Three rows in the predicate block, beside the other aliasing rows:
  - a symlink CYCLE in the destination path (ELOOP)   -> REFUSE
  - a destination that does not exist yet (ENOENT)    -> ALLOW
  - a component behind a regular file (ENOTDIR)       -> ALLOW

Teeth checked against the artifact the test loads, not the source: reverting
the condition to the swallow-everything shape in the compiled
test-home-guard.cjs turns row 1 — and only row 1 — red. The ENOTDIR row caught
a stale build during development, which is the point of asserting on the
compiled file.

CONTEXT.md and the resolveThroughLinks docblock both record the new behaviour,
so this does not repeat the prose-vs-code drift the round-4 finding was about.

The changeset's existing scope sentence now bounds "six writers" to the
`installRuntimeArtifacts` call tree and names `cmdGenerateDevPreferences` —
which resolves the same codex `home` override through `getGlobalSkillsBase` and
writes SKILL.md beneath it unguarded. It has no in-process caller today (its
only direct require-and-call is a spawnSync with HOME sandboxed), so it is
latent rather than live, and whether it belongs in this PR is raised with the
maintainer rather than decided here.

Verified: `npm run lint:ci` exit 0; full `npm test` 31330 tests / 31315 pass /
0 fail / 14 skipped, TMPDIR unset.

004e9dd741 fix(#3007): resolve Codex reasoning effort per model and make every clamp visible (#3765)
* test(#3007): failing-first suite for per-model Codex effort capability

RED by construction. Binds to behavior renderEffortForRuntime does not yet
have: an optional third `model` argument, a per-model advertised-level table,
`max` passing through instead of clamping to `xhigh`, `minimal` clamping to
`low`, `ultra` rejected outright, and clamp visibility (`requested`/`clamped`/
`reason`) so a downgrade is legible from resolver output rather than silent.

Two of these pin defects that exist on next today:

- `max` is discarded. Both Codex models whose catalog entries are retrievable
  (sol, luna) advertise `max`; GSD clamps it to `xhigh` and reports nothing.
- `minimal` is emitted to a model that refuses it. providerPresets.openai.
  haiku.low pairs gpt-5.6-luna with reasoning_effort "minimal", and luna's
  advertised floor is `low`. GSD is sending a value into a document Codex
  itself validates. The parity test is what pins that fixed, and it names the
  offending path/model/effort when it trips.

Also corrects tests/model-resolver.test.cjs:351, which asserted
renderEffortForRuntime('codex','max').value === 'xhigh' -- the defect pinned as
though it were a contract. ADR-443 recorded "Codex has no max" as fact and it
was true when written; Codex has since added both `max` and `ultra`. That is a
stale premise, so the assertion is corrected here rather than worked around.

The property test asserts the invariant the whole change exists for: a rendered
effort is always a level the target model actually advertises, or an explicit
rejection. There is no third outcome.

* fix(#3007): resolve Codex effort per model, and make every clamp visible

Codex declares supported_reasoning_levels per MODEL and validates against it,
so a single per-runtime capability set cannot be right for all of them. GSD's
was wrong in both directions at once.

`max` reaches Codex now. ADR-443 recorded "Codex has no max" as fact and clamped
max -> xhigh on that basis; it was accurate when written, and Codex has since
added both `max` and `ultra`. Every Codex model whose catalog entry is
retrievable advertises `max`, so the clamp was discarding a level the provider
supports, silently, on the most-used path.

`minimal` stops reaching Codex. No Codex model advertises it -- both retrievable
entries floor at `low` -- yet providerPresets.openai.haiku.low paired
gpt-5.6-luna with reasoning_effort "minimal". GSD was writing a value the
receiver validates and refuses into a file the receiver reads. Being
unconservative in what you send is the half of Postel's rule with no defensible
reading, so that preset is corrected and a parity test pins it.

`ultra` is refused rather than laddered. Codex's own catalog calls it "Maximum
reasoning with automatic task delegation": at ultra, effective_multi_agent_mode
returns Proactive and Codex spawns sub-agents on its own initiative, underneath
GSD's orchestration rather than inside it (#2167). It is a mode switch, not a
reasoning depth, so it is not added to the universal ladder -- which stays
provider-agnostic by ADR-443's design -- and it is rejected even for
gpt-5.6-sol, which does advertise it. Clamping it down to `max` was considered
and rejected: that silently discards what the user actually asked for.

Clamping is now visible. RenderedEffort carries requested/clamped/reason and
resolve-execution surfaces them. The previous table clamped correctly but
invisibly, so a user asking for `max` on Codex had no way to find out they were
getting `xhigh` -- exactly the failure mode the robustness principle's modern
critique warns about, and why "be liberal" has to mean "liberal and loud".

Also closes a latent trap found while reviewing the implementation: the clamp-up
loop walks the ladder upward, and for a future model advertising `ultra` but not
`max` it would have selected `ultra` as the clamp target -- re-entering by the
back door the mode the rejection above exists to keep out. A clamp may never
produce a value that a direct request for that value would refuse. Unreachable
with today's catalog, which is why no test caught it; a test now asserts the
invariant directly.

Signature stability is preserved: the third `model` argument is optional and the
two-argument form still resolves, against the family baseline. That form's
BEHAVIOR does change for `max` and `minimal`, and it must -- keeping the old
answer would have fixed the defect only where a model happened to be threaded
through and left it live everywhere else.

tests/model-resolver.test.cjs:351 asserted the defect as if it were a contract
and is corrected here rather than worked around.

* fix(#3007): close every review finding on the Codex effort alignment

Two isolated reviewers, correctness and security. Both found the same two
blockers, and the per-model work was inert on every surface that matters until
this commit.

BLOCKER — resolve-execution never passed the model and discarded the clamp.
cmdResolveExecution called the two-argument form and emitted only
effort_rendered/effort_param/effort_propagation, so the per-model table was
unreachable from production code (tests were its only caller) and requested/
clamped/reason were computed and thrown away. Requested outcome 3 names "the
effective rendered effort in resolver output" specifically, so the feature was
unmet on the exact surface the issue asks for. Now passes the resolved model and
emits effort_requested / effort_clamped / effort_clamp_reason, flat, matching the
existing key convention rather than introducing a nested object.

BLOCKER — the docs described output that did not exist. CONFIGURATION.md showed
a nested {"effort": ...} sample; the real result is flat and those keys were
absent entirely. A reference doc asserting a JSON path a reader can copy is worse
than no doc. Corrected against the actual emitted key set.

MAJOR — the argv channel still shipped both original defects. EFFORT_ARGV.codex
kept minimal in its supported set and still clamped max down to xhigh, so the
invocation-time and install-time channels disagreed about the same runtime's
capability: --host codex with max emitted xhigh while the generated TOML said
max. This is the repo's documented generative-fix-divergence class, so both
tables now cross-reference each other and a parity test fails if they ever
diverge again.

MAJOR — malformed catalog data failed OPEN and could crash the CLI. A null
_baseline became an EMPTY Set that is nonetheless truthy, so the nullish fallback
never fired and every effort rendered as null. And a non-array value made the Set
constructor throw at module load — model-catalog.cjs is required across the whole
CLI, so one bad JSON value killed every command, not just codex effort. Guarded
on size and filtered to array values; both degrade to the hardcoded baseline.

MAJOR — value widened to a nullable string with two consumers left behind.
runtime-artifact-conversion passed it straight into injectEffortFrontmatter (a
null effort key in generated frontmatter); install-effort-resolver still declared
a non-nullable return, a structural lie that silently defeated null checking.
Both corrected, both omitting the key on null — the same posture as 'inherit',
where omission means "follow the host default".

MAJOR — the per-model table is inert today, and the docs now say so. All three
shipped models advertise the same usable range and ultra (sol's only
differentiator) is rejected for every model, so no observable output differs by
model. The table stays because Codex declares capability per model and the sets
are free to diverge — a single per-runtime assumption is precisely what went
stale and produced this issue — but overselling it as a visible per-model feature
would have been the same class of error as the doc blocker above.

Tests: three passed under a full revert and are strengthened rather than deleted,
since each guards a real contract (#3533's inherit rule, the undeclared-host
rule, off-ladder handling) — they now also assert the clamp-visibility fields,
which only exist after this change. The fast-check property is kept for its
shrinking, and a deterministic nested loop over the full cross-product now sits
beside it so coverage is exhaustive rather than sampled.

Also folded in earlier: bin/install.js generated the Codex TOML with the two-arg
form and would have written a literal null reasoning effort on the ultra path;
CONTEXT.md's Model Catalog Module glossary entry now records CODEX_MODEL_EFFORT.
The installer defect was found by the co-change gate, not by a reviewer —
install.js is a historical co-change partner of model-catalog.cts that this diff
had not touched.

* test(#3007): correct assertions that pinned Codex's stale effort premise

Thirteen pre-existing tests encoded "Codex has no max" as fact and failed on the
shipped commit. Every one is a stale pin, not a defect: each was probed against
the built module before its expectation was changed, and none failed for a
reason other than this premise correction.

Kept as its own commit per CONTRIBUTING — a test-fixture correction made stale
by a production change must not ride inside another commit, because the
release-sdk hotfix cherry-pick filter routes by subject prefix and a correction
buried under the wrong prefix ships a half-state (v1.42.3, #3621).

The most valuable one was tests/model-resolver.test.cjs's cross-provider
validity invariant, which hardcoded the Codex enum as
`minimal|low|medium|high|xhigh` and failed with "real API would 400". That
message is now false in both directions: Codex accepts `max`, and rejects
`minimal`, which no model advertises. The enum is corrected to
`low|medium|high|xhigh|max` and the guard is kept intact — it is exactly the
"would the real API refuse this" check worth having, and it was right to fail
here. It simply carried the stale fact in its own fixture.

Test NAMES were corrected alongside their assertions wherever the name asserted
the old behavior — "max is Anthropic-only", "max clamps to xhigh", "minimal
passthrough". A renamed test that still claims the old thing is worse than a
failing one, and a green test whose name states a falsehood is how the next
reader inherits the wrong premise.

Both channels are covered: install-time (renderEffortForRuntime, and the
generated .toml in install-runtime-artifacts) and invocation-time argv
(effort-surface-axis). They were deliberately brought into agreement in this
change, so their assertions had to move together.

Each site carries a #3007 comment recording that Codex gained max/ultra and that
capability is declared per model, so a future reader can tell this was a
deliberate premise correction rather than a test bent to fit an implementation.

* test(#3007): separate the effort-precedence case from the clamp case

The previous stale-assertion pass over-corrected one test. It saw
`effort: { default: 'max' }` on codex expecting `effort_rendered: 'xhigh'`,
assumed the xhigh came from the max→xhigh clamp #3007 removes, renamed it to
"max passes through" and changed the expectation to `max`. The remote runner
disagreed.

Reproduced against the real CLI: with that config and `gsd-planner`, the
resolver emits `effort: "xhigh"`, `effort_requested: "xhigh"`,
`effort_clamped: false`. The xhigh is produced by effort-resolution PRECEDENCE —
gsd-planner is heavy/opus tier and its routing-tier default outranks
`effort.default` — so `max` never reaches the renderer at all. The test says
nothing about clamping and never did; it only looked like a clamp pin because
both mechanisms happened to yield the same string.

Restored to `xhigh` and renamed to say what it actually tests. It now also
asserts `effort_clamped === false` and `effort_requested === 'xhigh'`, which is
what makes it impossible to mistake for a clamp pin again: those two fields prove
the value is what the resolver produced rather than something the renderer
downgraded. Before #3007 there was no way to tell the two apart from the output —
which is precisely why the previous pass could not tell them apart either.

Added the test that was actually missing: `effort.agent_overrides`, which
outranks the tier default, so the requested level genuinely reaches the renderer
and `max` survives to `effort_rendered` end-to-end through the real CLI. Verified
by probe before asserting.

One test now pins the precedence rule and the other pins the #3007 behavior, and
neither can be read as the other. That the clamp-visibility fields are what
resolved this is a small argument for having added them.

* chore(#3007): backfill changeset pr number to 3765

* test(#3007): put model-catalog under the mutation gate

The Stryker shard showed as `skipping` on this PR despite the diff rewriting
model-catalog's effort logic. That was legitimate, not a detection bug:
`model-catalog` was never in scripts/mutation-matrix.cjs's COVERED map, so the
whole module — including everything #3007 touches — sat entirely outside
mutation scoring with has_work "false".

Registered, with a dedicated spawn-free surface. tests/model-catalog.unit.test.cjs
is new: 44 in-process tests, no runGsdTools, no child process, no filesystem, no
temp dirs. That shape is not stylistic — it is the #2790 precedent this file
already documents. Stryker's command runner treats a whole `node --test <file>`
invocation as ONE test costing whatever its slowest case costs, and re-runs it
per mutant, so pointing a shard at tests/model-resolver.test.cjs (which uses
runGsdTools throughout) would reproduce exactly the 15-minute shard-cap
cancellation #2790 hit. The integration file is unaffected and keeps running in
full in the normal test job.

Coverage spans the module rather than only the diff, because the score is
measured over the whole file: effort rendering across every model and ladder
level in both channels, the prototype-chain host guard, the exported enums and
maps, isAnthropicFlavoredModel's provider namespacings, the profile projections,
nextTier, and mergeEffortTierDefaults. The last two were nearly left out and are
worth naming — every uncovered exported function is score given away, and
mergeEffortTierDefaults turned out to have a genuinely interesting contract
(#3531: a partial override merges over the built-ins rather than replacing them,
and isValid gates the VALUE, not the tier name, so an unknown tier key is still
merged in). Every expectation was probed against the built module before being
asserted.

minScore is 1 and that is a PLACEHOLDER, flagged as such in the registry comment.
Floors in this repo are measured, not chosen — the existing entries sit at 94, 75
and 56 — and they can only be measured in CI, because mutation shards run
`node --test`, which is hard-blocked locally. The first CI run on this branch
reports the real number and the floor gets ratcheted to it before merge. A
placeholder of 1 reaching `next` would make the gate decorative: it would pass
whether or not a single mutant is ever killed.

Note the target is "never regress from measured", not a fixed 80 — planning-inspect
sits at 56 and is documented as an accepted ratchet candidate.

* test(#3007): bootstrap model-catalog's mutation floor legally

The placeholder floor was structurally illegal and the remote run said so.
tests/mutation-matrix-ratchet.test.cjs guards the guard: every COVERED module
must carry a matching RATCHET_BASELINE entry in the same diff, minScore must
EQUAL that baseline, and it must be at least 50. `minScore: 1` failed all three.
That is the ratchet working exactly as intended — a floor nobody can satisfy
accidentally is the point of it.

Bootstrapped at 50 in both places. Fifty is not a measured score and the comment
says so plainly: it is the minimum the guard permits, and it coincides with
Stryker's own configured `break` threshold, so it is the lowest legal starting
point for a module that has never been measured. It still must be ratcheted to
floor(measured) - 1 before this PR merges.

Also corrected a real defect in the file's own instructions. "HOW TO UPDATE"
step 1 read "Run the per-module Stryker shard locally" — which cannot be done
here, and which the same file contradicts eighty lines further down, where the
#2790 scores are recorded as "not a local run; mutation shards run `node --test`,
hard-blocked in this repo's local environment". stryker.config.mjs confirms the
command runner invokes `node --test` once per mutant, and
.claude/hooks/block-local-node-test.sh denies exactly that. So the documented
first step sends the next contributor at a wall. Rewritten to describe the path
that works — push, read the measured score off the CI shard, then set the floor
and its baseline together in one diff — and to say why local measurement is not
available, so nobody rediscovers it the slow way. GOODHART SAFETY is untouched.

The two-step is inherent to the environment rather than a shortcut: a floor
cannot be measured before the first CI run exists, and the guard rightly refuses
to accept an unmeasured one below its minimum.

* test(#3007): ratchet model-catalog's mutation floor to its measured score

The shard ran in CI and reported 59.62% — 248 mutants killed, 168 survived, no
timeouts, no errors (run 32605073352, job 97108869486). Floor set to 58 per this
file's own rule, minScore = floor(measured) - 1, which is the same arithmetic
every sibling entry used: 57.03 to 56, 76.58 to 75, 95.65 to 94.

Both halves moved together, because the ratchet guard asserts minScore equals its
RATCHET_BASELINE entry and would reject them drifting apart.

The spawn-free unit surface is vindicated by the clock: 57 seconds, against a
15-minute shard cap and a 9m46s frontmatter shard in the same run. That was the
whole reason for creating tests/model-catalog.unit.test.cjs rather than pointing
the shard at tests/model-resolver.test.cjs — #2790 recorded shards being
CANCELLED at that cap when they targeted a runGsdTools-heavy integration file.

The registry comment is rewritten rather than deleted. It previously warned that
the floor was provisional and must not ship that way; leaving that text next to a
measured floor would make the file lie in the other direction. It now records the
measurement the way the sibling entries do, including that 59.62 sits below
TARGET (80) and is therefore a ratchet candidate like planning-inspect at 56 —
comfortably clear of its own floor with real room to grow. Raise it as the tests
improve; never lower it.

Worth stating plainly: 168 surviving mutants is not a clean bill of health. It is
an honest floor for a module that had NO mutation coverage at all an hour ago,
and it is now pinned so it cannot silently regress.

682eaae3f0 enh(#2876): retire the dead and pass-through exports from bin/install.js (#3615)
* enh(#2876): retire the dead and pass-through exports from bin/install.js

The installer exported 197 names and had zero production consumers - every
non-test require of it repo-wide sits inside a comment. Its interface was
shaped by test access, not by callers.

Removes 9 dead exports and 61 pass-throughs, repointing their tests onto the
extracted modules' own interfaces. 197 down to 127.

Every count in the issue was wrong: 197 exports not 188, 9 dead not 12, 61
pass-throughs not 49, 44 test files not 42 - and the audit itself then missed
7 more consumer files. restoreUserArtifacts was on the dead list but ceased to
exist in phase 6, and two _GSD_EFFORT_MANIFEST_* names listed as dead are now
genuinely asserted, so acting on that list would have deleted live exports.

7 of the 9 dead names collide with an independent declaration that install.js
delegates TO. Each removal was justified by which declaration a reference
resolves to, never by whether the name appears somewhere.

Coverage parity was the gate rather than test greenness: per-file counts were
captured before any edit and diffed after. 44 of 45 files are byte-identical;
the single delta is one added assertion, not a loss.

The sweep for scattered require sites found two forms static grep misses -
require(VARIABLE) and multi-line require() - plus tests asserting that
install.js re-exports the SAME object, which now assert retirement instead.

* fix(#2876): close review findings — restore the duplicate-body guard, sweep orphaned code

Both review engines found real defects in the first cut.

The DEFECT.GENERATIVE-FIX single-owner guard from #1511 had been repointed
from a reference-identity check to install.X === undefined. Those are not
equivalent: the guard exists to catch a duplicate function body reintroduced
into install.js, and the replacement passes cleanly if that duplicate is used
internally and never exported. It now walks bin/install.js's real top-level
bindings, so it catches a duplicate under either shape, exported or not -
strictly stronger than the check it replaced. Proved by injecting a duplicate
and watching it go red.

That weakening survived the coverage-parity gate because the assertion count
never moved. The gate compares counts, so an assertion that changes meaning
rather than number is invisible to it.

Removing the exports had orphaned their wrapper bodies: 14 dead wrappers, 9
consts and 9 destructure entries, several pre-existing and found by the same
sweep. Dead code left in the file this phase exists to shrink.

Three more comments claimed re-exports this phase removed, and tests were
reading Cursor and Windsurf hook constants from install.js's local copy while
calling functions from the hooks surface - equal today, with nothing holding
them equal. The local consts now reference the owning module.

3ab0007164 enh(#2875): materialization primitives — durable user-artifact staging and descriptor-authoritative agents (#3600)
* fix(#2875): stage user artifacts durably across install wipes (#1874-F19)

preserveUserArtifacts held user files only in an in-memory Map across the
wipe, so any process death between preserve and restore lost them outright.

Seven call sites, not the four the issue records. Three of them never called
the helper at all - they open-coded the same read/wipe/write - so searching
for callers under-counted by construction; the extra sites were found by
sweeping for the pattern instead.

The worst is the mainline install path, where the crash window spans the
entire gsd-core tree copy rather than a single rmSync.

Adds src/user-artifact-staging.cts: durable on-disk staging with a record
written after the copies land as the commit point, plus recovery of orphaned
batches on the next run - without recovery the staged bytes survive but the
user's file is still gone, which would pass its own test while delivering
nothing.

Routes copyPreservingSymlink through installFs() so staging cannot bypass the
install fs seam, and reunites its symlink-safety docblock with the function it
documents.

* docs(#2875): amend ADR-3574 with four claims disproved by implementation

Implementing Phase 6 disproved four statements the ADR rests on. The central
decision - no single materializer - is unaffected and stands.

Corrected: decision 3 was already satisfied, so nothing was extracted; the
agents-bypass runtime set omitted claude, kilo and opencode, and closing it
needed three new pieces of descriptor contract rather than proceeding on its
own terms; three of the four blockers the layout comment names were already
stale; and F19 is seven call sites, not four.

Records the generalizable lesson: the defect is the pattern of holding user
data in memory across a wipe, not the helper, so searching for callers of the
helper under-counts by construction.

Also resolves the ADR's open question on USER_OWNED_ARTIFACTS membership, and
notes that copyPreservingSymlink needed routing through the install fs seam
before it could be reused.

* fix(#2875): close dangling-symlink blind spot and harden staging recovery

An adversarial review found the F19 staging work shipped red and unsafe.

Root cause, shared by two arbitrary-write findings: hasExistingSymlinkBetween
missed dangling symlinks in both its root check and its per-segment walk,
because it probed with existsSync, which is false for a link whose target does
not exist. Fixing only the new module would have reused a guard that was
itself blind. This guard protects the whole install tree.

Recovery no longer throws: it degrades per entry and per file, so one bad
batch cannot block the others. Previously an unrecoverable entry propagated
out of the first statement of install and uninstall, before the cleanup that
would have removed it - wedging the installer permanently.

Partial fs adapters now throw on any omitted method instead of silently
reaching the real filesystem, closing the trap that let a test poison list
pass while real IO happened.

Staged names must be flat, recovery refuses a dangling destination symlink,
and a batch whose recovery genuinely failed is no longer swept - it was
discarding the only durable copy of the file it had just failed to restore.

Replaces three tests that could not fail, including the one labelled negative
proof.

Known limitation, documented not closed: concurrent installs sharing a staging
key can still lose a batch. A real fix needs a cross-process lock.

* enh(#2875): make the descriptor authoritative for the agents kind

Deletes the inline agent-staging loop in bin/install.js and the
_DESCRIPTOR_AGENTS_RUNTIMES set, so every runtime materializes agents from
its capability descriptor instead of an inline hostBehaviors dispatch.

Closing it needed three pieces of contract the descriptor pipeline never had,
all reducible to one missing input - per-agent resolution context: a
frontmatter-extensions step for claude's effort and disallowedTools, per-agent
model-override resolution for kilo and opencode, and a named branding
converter for hermes, whose rewrite data was already declared.

Seven runtimes were on the loop, not the six the design recorded - kimi-code
was found by a golden fixture, not by analysis. claude-local and kimi-code
both silently lost their agents mid-change; the fixtures caught both and the
cause was fixed rather than the fixtures regenerated.

A parity harness gates the migration: both pipelines over identical inputs,
byte-identical output including filenames, per runtime. It is demonstrated
red before being trusted. Surface and install paths converge for all seven,
which also fixes surface previously writing no agents for these runtimes.

Codex's config.toml strip stays put - it mutates host config, which no
descriptor kind models.

Also routes install-model-override-resolver and install-effort-resolver
through the install fs seam. Both leaked real filesystem IO from the install

* docs(#2875): record the agents-descriptor migration and correct the ADR count

The _DESCRIPTOR_AGENTS_RUNTIMES allow-list no longer exists, so the host
integration guide told readers to join a set that is gone. Replaces that with
what is now true - declare an agents entry and it installs, on the surface
path as well as install - and points anyone needing a per-agent transform at
the three extension points rather than at a new inline branch.

Corrects the ADR amendment: seven runtimes were on the inline loop, not six.
kimi-code was found by a golden fixture going red, not by reading. That is the
third short count this phase, all from enumerating by symbol or set membership
when the thing that matters is a behavior.

Adds the Changed changeset for the surface-path convergence.

* docs(#2875): amend ADR-2866 - claude global always wrote agents on disk

The claude row's global=[skills] described what capability.json declared, not
what the installer wrote. bin/install.js's inline agent-staging loop was never
scope-gated and never consulted the descriptor, so a claude --global install
has always written agents/gsd-*.md.

Phase 6 closes the gap by deleting that loop and declaring agents on claude's
descriptor at global scope. On-disk bytes are unchanged - the golden fixtures
did not move, which is the evidence that the descriptor, not the installer,
was incomplete.

#2218 is unaffected: agents are not trigger-bearing, so the wider row does not
introduce a new shadowing case.

Records the warning that an incomplete descriptor is invisible while a second
code path silently does its work, and only surfaces when the two are forced
into agreement.

* fix(#2875): close review findings across staging, agents and the parity harness

Two independent reviews of this branch found defects the local gates missed.

Security: a dangling symlink at a migration destination allowed writing
outside configDir - the same class this change claimed to close, missed at the
terminal write of the flow being added. The staging-root resolver threw as the
first statement of install and uninstall, so a hostile symlink bricked both,
and symlinked-configDir users lost uninstall as well as install; it now
degrades instead of aborting. Recovery gained a source-side symlink check and
now refuses a relative destDir, which resolved against cwd. Converter dispatch
gained a runtime allowlist - lint-time validation stopped mattering once this
branch promoted that dispatch from the surface path to real installs.

Correctness: claude --local --minimal exited 1 because the minimal profile
legitimately yields zero agents and the new path treated that as a failure.
cline --local silently lost its agents - its descriptor declared none while
the deleted loop wrote them unconditionally. The agents prune was widened to
any gsd-* entry and destroyed user files it never owned.

The parity harness, on which the migration's safety argument rested, drove a
synthetic registry and never byte-compared the shipped descriptors; two of its
trap rows could not fail. It now drives the real registry across 13
runtime-scope rows including kimi-code and cline-local, and its red-proof is
demonstrated by corrupting a live capability.json. Three goldens that had
encoded the cline regression as expected behavior were corrected.

Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

* fix(#2875): close findings from both mandated review engines

/security-review found the staging source-side walk honouring
GSD_ALLOW_SYMLINKED_DEST, an opt-in documented as relaxing only the write
destination. A symlinked files/ component dereferenced because
copyPreservingSymlink lstats the leaf only, so an intermediate link is
followed. The source walk no longer honours the opt-in; the destination check
still does.

/code-review spec axis found this branch had reintroduced its own bug:
migrateLegacyDevPreferencesToSkill's new symlink refusal threw unguarded after
the legacy dir was wiped and before the staged batch was restored, so a
planted symlink bricked uninstall permanently and orphaned the batch. Refusal
kept, abort removed.

kimi-code local silently lost its agents, the same class as the cline bug, and
the parity harness recorded that exclusion as intentional - the third test in
this branch to pin a regression as correct.

--minimal now creates an empty agents/ dir that never existed. Behaviour
restored rather than softening the changeset, so its byte-identical claim
stays true.

Standards axis: try/finally removed from twelve test bodies, fast-check
properties added for parseOwnerPid, boundary coverage at the grace window and
the ancestor-probe depth, a parity assertion for the staging-root helper
duplicated across two files, and the 8-deep config walk deduplicated.

Records 60-review.json with every finding and disposition from five passes,
including the smells left unfixed and why.

* fix(#2875): prune stale agents unconditionally in minimal mode

The previous round stopped an empty agents/ directory being created when the
resolved profile yields no agents. That was implemented by skipping the agents
kind entirely, which also skipped its stale-agent prune - so a full to minimal
downgrade left stale gsd-* agents behind.

The deleted inline loop pruned unconditionally and only skipped writing. Those
are three separate conditions, not one: prune always, write only when there is
something to write, create the directory only when writing.

Both call sites now run _removeGsdEntries before the empty-staged early exit.
The symlink-escape guard moved with it, since the prune also touches dest.
Codex .toml agents and the config.toml stanzas are cleaned again, and
user-owned agents are still preserved.

The agents/ directory is left in place after a prune empties it, matching
every sibling kind - none of them remove the destination directory itself.

Golden fixtures confirmed byte-identical: the prune is a no-op on a fresh
install, so fixture generation is unaffected.

* docs(#2875): document interrupted-install recovery for user-owned files

The durable-staging fix is invisible to the user it protects. Someone whose
install died mid-flight has no way to know USER-PROFILE.md was staged before
the delete, that the next run restores it, or that recovery happens at the
start of that run rather than in the background.

Written as the task the user has - finish the interrupted command - rather
than as a description of the mechanism, and states what it will not do:
overwrite a file already present, or touch staging belonging to another
install still running.

* test(#2875): assert the J8 model override without building a regex

CodeQL flagged incomplete string escaping: the assertion interpolated the
override value into a RegExp while escaping only forward slashes, which is
meaningless in a constructor, leaving real metacharacters unescaped.

The failure direction was the dangerous one - a metacharacter would have made
the match more permissive, so the row would pass when it should fail. That
matters here because J8 exists precisely because an earlier revision was a
tautology; the rewrite reintroduced a different way for the same assertion to
stop discriminating.

Replaced with a line-wise exact match, so no regex is constructed at all.
Swept the other test files this branch adds; no sibling instances.

lint:ci passed on the original - lint-no-adhoc-regex-escape matches a full
metachar-escape copy, so a single slash replace slipped under it.

a4a02a7a01 enhance(#2874): return the executed plan and route install IO through a seam (#3568)
* test(#2874): add failing-first gate for the executed-plan return

Four rows from the matrix's red-first order. E3 pins the one early return,
for the opencode family, where a void-shaped hole would otherwise survive
unnoticed. E13 sweeps every runtime in the registry - enumerated from the
registry rather than hardcoded, so a runtime added later cannot slip past.
F2 proves absence of real filesystem contact rather than merely that the
happy path ran, which is the difference between a complete seam and a
partial one.

G1 and G3 are the additive guard and must be green before and after. G3
deliberately leaves the two existing adapter test doubles untouched: if
this change required editing them it would not be additive, and the
acceptance criterion would be unmet.

No production code. All 19 runtimes install without throwing today, so
E3 and E13 fail on the undefined comparison alone.

Refs #2874

* feat(#2874): return the executed plan and route install IO through a seam

installRuntimeArtifacts returned void, so its correctness was observable
only by re-reading disk. It now returns what it executed - per kind, per
scope - including on the combinedFamilyInstall path, which was the one
early return where a void-shaped hole would have survived unnoticed.

Failure still throws rather than becoming an ok:false return, so control
flow is unchanged for both existing callers. A best-effort cleanup that
fails is still swallowed, but is now visible in the returned value rather
than silently absent.

The fs seam is ambient rather than threaded. Explicit deps through
install-profiles and the 3000-line conversion module was impractical; the
tradeoff, the synchronous-only re-entrancy assumption, the restore
guarantee and the partial-adapter fallback trap are all documented at the
seam. findInstallSourceRoot and its sibling stay unrouted by design -
they locate the package's own source, not the install destination.

readCmdNames keeps a second implementation because the standalone CLI
that owns the original cannot require the compiled adapter without a
build-order dependency on its own output. A parity test fails if the two
ever disagree.

Refs #2874

* chore(#2874): gitignore the new build artifact

install-fs-adapter.cjs is tsc output from src/install-fs-adapter.cts, not
a tracked source file. It was added to eslint's ignore list but not to
.gitignore, so it landed as a tracked file - the third time this step of
the new-.cts ripple has been missed on this epic.

Refs #2874

* fix(#2874): close two seam leaks and correct a false comment

A correctness review found the seam still leaked in two places, both
subtler than the three already closed.

readGsdCommandNames was routed when it should not have been: it reads the
package's own commands directory, which a destination-fake is never
seeded with, so under a fake adapter it returned an empty or wrong roster
instead of failing loudly. It now reads real fs, matching the precedent
already documented for findInstallSourceRoot.

cleanupStagedSkills ran raw rmSync from a process exit handler, which is
real filesystem work deferred past the point where withInstallFs has
restored - the one thing the synchronous-only contract exists to
exclude. Staging now captures the adapter that created each directory and
cleanup replays it, so a real install cleans up exactly as before and a
fake-staged path never reaches the real filesystem.

Also corrected a comment claiming the migration reads were an unrouted,
untested residual gap. They are routed and exercised; a comment
understating the seam is as corrosive as one overstating it in a module
whose trust rests on being honestly documented.

Refs #2874

* test(#2874): migrate the exemplar group and cover the matrix

AC3's exemplar migration lands in place: the qwen install group now
asserts skills and agents destinations from the returned plan in one
deepStrictEqual instead of probing the filesystem for each.

Nine facts the old probes established were enumerated first. Two moved to
the value assertion; seven were retained deliberately - per-file SKILL.md
existence, the VERSION file written outside this function, the manifest
content, and the post-uninstall absence checks all sit outside the plan's
per-kind contract. A migration that quietly asserts less looks like a win
and is a regression, so the enumeration is the guard rather than the
line count.

Also implements the rest of the matrix: the executed-plan shape, adapter
failure modes, the security-boundary rows including a fake that cannot
certify an install the real filesystem would refuse, cleanup visibility,
and two seeded property tests. Only the two external CI gates are left
unticked, because self-certifying them would be a claim rather than a
check.

Refs #2874

* fix(#2874): restore streaming hashes and derive F2 from the boundary rule

The checkpoint found three things reasoning had missed.

sha256File had been converted from raw-fd streaming to a single
readFileSync on the assumption that GSD artifacts are never large. A test
named for exactly that contract already existed and went red. Streaming is
restored, now routed through the adapter, which gains openSync, readSync
and closeSync. The contract was the specification; the assumption was not.

Three existing tests inject faults by monkeypatching real fs. They broke
because mkInstallTempDir stopped calling real mkdtempSync, not because of
any binding subtlety - the real adapter was already late-bound. It now
calls the real function when no fake is injected, so a monkeypatch applied
after import is still seen and the additive contract holds.

F2 poisoned real fs by method, so a deliberately unrouted package-source
read failed a correct design. It now poisons by path: destination IO is
forbidden, package-source IO is allowed and positively asserted. The claim
was always zero real destination IO, and the test now derives from that
rule instead of coincidentally matching it.

Refs #2874

* docs(#2874): add the contributor how-to for plan-based test migration

The phase gate caught a real gap. The docs plan was Reference plus
Explanation only, and every CI check would have passed, because the
docs-required lint only verifies that some file under docs/ moved.

But this phase exists to demonstrate a pattern for follow-on work, and
that work is other contributors migrating probing test groups. The
sequence has two live traps - a partial fake silently falls back to real
fs, and the seam is ambient and synchronous-only - plus one discipline
nobody infers: enumerate the facts before converting, or you assert less
and call it a win.

The page carries the qwen migration's arithmetic, nine facts enumerated
and only two converted, because a reader seeing only the diff would
reasonably conclude the pattern is to replace probes wholesale.

No locale mirrors: none of the four carries any contributor-only how-to,
so a single translated file would manufacture parity rather than provide
it.

Refs #2874

* chore(#2874): backfill changeset pr number

* test(#2874): normalize both sides of the G1 tree comparison

G1 failed on Windows only, deterministically on both shards. The defect
was in the test helper, not production.

_computePathPrefix posix-normalizes the resolved config dir
unconditionally, so on Windows the path embedded in every emitted
SKILL.md body is forward-slash form. hashDirTree stripped against the raw
backslash path from mkdtempSync, so the substring never matched and each
install's unique temp suffix stayed baked into every file - all fifteen
skill bodies hashed differently for two runs that had written identical
bytes.

Both sides are now normalized unconditionally rather than gated on
path.sep, matching the rule this repo already records: backslash paths
arrive on Linux too.

Production code is untouched and was verified correct. Normalizing this
away on the production side would have hidden a real portability bug if
one had existed.

2d72577e07 test(#2873): align generated-doc counts and drop text-anchored assertions
The remote runner caught three families this branch caused. W028 moves the
generated health table to 35 rows / 32 rules, so gen-health-docs.test.cjs
is updated in both its assertion and its title - a title carrying the old
count is a test that lies about what it checks.

The three negative-proof rows no longer match a literal report substring.
They assert the typed signal instead: buildShadowReport reports
not_shadowed, renderShadowReport returns no lines, and stderr contains
none of those lines. That takes the new allow-test-rule annotations to
zero rather than lifting the ceiling to fit them.

health.md's growth is acknowledged at its existing key. A second fragment
on the same key is a duplicate-ack error, and the re-arm path only fires
on a reworded reason at the same key.

147856040b fix(#2873): close review findings across fences, sanitizer and docs
Isolated security review found resolveSpecRootReference's fence tracker
toggled on any delimiter, so a backtick fence could be closed by a tilde
one and an include in the gap was rewritten inside a code block. Fixed by
reusing scanFencedBlocks - the canonical engine already behind
stripFencedCode and extractFencedBlock - rather than carrying a fourth
copy of fence detection, which also closes the duplication the standards
review flagged.

sanitizeForRender now strips combining marks and zero-width characters
alongside the ANSI, control and bidi classes it already handled.

Adds the C, E and F matrix rows the spec review found missing, including
installer-level coverage that spawns the real install rather than calling
the report builder. Ships the how-to, the reference and command docs in
five locales, the changeset, the inventory and glossary entries, and
regenerates health.md for the new W028 rule.

2641e6cb67 feat(#2873): detect cross-scope shadowing and reach the local spec tree
4a - the detection floor. A shadowed install now reports which triggers are
shadowed and which scope wins, at install time and through a new W028
/gsd-health diagnostic. Exit codes are untouched: a shadowed install is a
warning, not a failure. Only triggers whose stem exists at BOTH scopes are
reported, so a global full profile beside a local core profile no longer
names local artifacts the user does not have.

4b - spec-root reachability, claude runtime and global scope only. The
winning global skill stops carrying a static workflow @-include and instead
resolves its spec at runtime: prefer the project-local copy, fall back to
the global one, stop if neither exists. Every other @-include stays static,
and the local emission is byte-identical. It runs after the staged-skills
rewrite pass, whose claude branch would otherwise mangle the literal tilde
path into an undocumented $HOME form.

Also fixed inline: readInstallManifest classified a top-level JSON array as
an installed v1 manifest, because typeof [] is object.

69e7afd0c7 chore(#3212): bounded quantifiers over document content — prohibition with teeth — Phase 4 (#3441)
* feat(#3415): ship local/no-unbounded-quantifier, burn down ReDoS class

Phase 4 of epic #3212 (ADR-3212 §5/§7, the final phase). New rule flags
an unbounded */+/{n,} quantifier over a broad character class
([\s\S], dotAll ., or a 1-2-unit negated class like [^\n]/[^)\n] — the
exact #2128-fixed shape) applied to a regex whose match target is
data-flow-traced to readFileSync content.

eslint-rules/lib/readfilesync-trace.cjs extracts the data-flow tracer
shared with no-crlf-fragile-split (Phase 2) rather than a second copy
— no-crlf-fragile-split refactored onto it with zero behavior change,
parity-tested.

Real triage, not 798 mechanical edits: the ADR's census (2026-08-08)
screened every unbounded quantifier in the tree unscoped. Correctly
scoped to readFileSync-derived content (matching Phase 2's own G2/G3
scoping), the rule found 162 real hits across two detection waves — the
second wave (93) surfaced only after a genuine off-by-one bug in this
rule's own first draft was caught while writing its RuleTester tests
and fixed (the bug silently missed every directly-quantified [\s\S]*
with no gap before the quantifier — exactly the class this rule exists
to catch). 3 hits landed in production src/ (commands.cts, milestone.cts,
roadmap.cts) and were each empirically timed against adversarial input
(matching #2128's own measured-not-assumed precedent) — all confirmed
linear-time/benign, left unbounded with a measured-evidence comment
rather than mechanically bounded. The remaining 159 are test-file
fixture parsing (test-author-controlled, fixed-size content, not
adversarial input) — each suppressed with a specific, non-generic
reason. Zero functional behavior changed anywhere in this diff.

tests/no-pending-3212-markers.test.cjs locks the epic's own closing
invariant (ADR §7: "assert zero pending #3212 markers remain") — ground
truth confirmed trivially true today (no phase left any such marker
behind), now regression-locked going forward.

* fix(#3415): correct rule category mislabel, add CI test-scope entry

An orthogonal Standards-axis review found eslint-rules/no-unbounded-quantifier.cjs
mistakenly carried meta.docs.category: 'Portability', copied from a sibling
rule without realizing what that implied: docs/contributing/cross-platform-
portability-rules.md governs an ADR-1703 rule family under a hard "zero
escape hatches" contract (tests/portability-rule-disable-ban.test.cjs's
PROTECTED_RULES bans eslint-disable for those rules entirely). This rule is
not part of that family — it's ADR-3212 (ReDoS/CWE-1333), a different epic —
and its eslint-disable-next-line suppressions (159 of them, added earlier
this same phase after empirical benign-verification) are an intentional,
correct design, not a bypass. Corrected to category: 'Best Practices',
matching the actual precedent (no-adhoc-regex-escape.cjs, Phase 1 of the
same epic, which is also correctly outside PROTECTED_RULES), and the rule's
own docstring now states this explicitly so a future reader doesn't have to
re-derive it.

Also registers a new scripts/ci-test-scope.cjs bucket so editing this rule
or the shared eslint-rules/lib/readfilesync-trace.cjs helper re-runs their
own test suites under targeted CI selection — was previously unregistered
and invisible to that fast-path (this PR's own gsd-test checkpoint runs the
full suite regardless, so this only affects future narrowly-scoped PRs).

* fix(#3415): bound no-unbounded-quantifier's own scanner (CWE-1333, ironic)

Security review found the rule meant to catch algorithmic-complexity bugs
had one of its own: hasUnboundedBroadQuantifier's negated-class inner
scan walked from each `[^` occurrence to the next `]` (or EOF) with no
bound, while the outer loop only ever advanced by one character — O(n²)
total work on a pattern with many unclosed `[^` runs. Runs unconditionally
inside checkPattern on any `new RegExp('literal string')` argument in any
linted file, before the (cheap) readFileSync data-flow gate — so a single
crafted string literal, no valid regex syntax required, could make
`npm run lint` / CI hang.

Empirically confirmed both the bug and the fix: pre-fix, n=4000/8000/
16000/32000 chars took 30.8/115.6/463.8/1874.3ms (~4x work per 2x n,
quadratic); extrapolated, the 300000-char repro from the finding would
run ~165s. Post-fix (bail the inner scan once units exceeds the rule's
own 1-2-unit scope, rather than continuing to hunt for a closing `]`),
the same 300000-char input runs in 8.7ms via the real rule module,
independently reconfirmed at 18ms via a fresh Linter.verify() call.

New regression row in tests/no-unbounded-quantifier.rule.test.cjs
asserts the RuleTester run on a 50000-char adversarial pattern
completes and returns a defined result — no wall-clock assertion
(CLAUDE.md Clock Seams / local/no-elapsed-assertion).

b9adedbc86 fix(#3151): stop emitting effort: into skill frontmatter (cache invalidation) (#3425)
Claude Code applies SKILL.md effort: as output_config.effort; any change from
the session baseline invalidates the prompt cache at BOTH scope boundaries
(entry + exit, the latter often machine-fired via subagent-completion
notification). The reporter's owned measurement confirms it: /gsd-progress
(effort:low) in a medium session → cache_creation 63,404 (entry) + 18,589
(exit), while a no-effort skill shows none. ~76% of invocations paid in full.

Fix (trek-e AC#2/AC#4): convertClaudeCommandToClaudeSkill no longer emits
effort: into Claude-runtime skill frontmatter (src/runtime-artifact-conversion.cts
+ duplicated bin/install.js). normalizeClaudeSkillEffort removed (dead). The six
declaring skills (plan-phase/execute-phase/autonomous/next/progress/stats) no
longer carry effort. Source command files keep effort (input, used elsewhere);
the separate agent-effort surface (#3160) is untouched.

Tests: install-runtime-artifacts #769 block flipped to assert effort is ABSENT
from installed SKILL.md + converter output (the AC#4 behavioral coverage).

dc3c81e93d chore(#3212): src/pattern.cts is the sole owner of runtime-value regex construction — Phase 1 (#3416)
* test(#3412): failing-first suite for the pattern-construction seam

Phase 1 of epic #3212 (ADR-3212 §1/§2/§7). Tests only — src/pattern.cts
and eslint-rules/no-adhoc-regex-escape.cjs do not exist yet, so both
suites fail with MODULE_NOT_FOUND, which is the intended RED.

Locks the measured behavior rather than the assumed behavior:
RegExp.escape hex-escapes the leading character of nearly every string
("abc" -> "\x61bc"), so the suite asserts match-equivalence against an
inlined historical oracle (the implementation being deleted) rather
than byte-equivalence of pattern text — 200 seeded fast-check runs plus
a fixed corpus, 0 mismatches. Also locks the latent character-class
range bug this phase fixes as a side effect: a hyphen-bearing value
interpolated into [...] currently forms a real range and matches an
unintended character; post-migration it must not.

* chore(#3412): src/pattern.cts owns runtime-value regex construction

Phase 1 of epic #3212 (ADR-3212 §1/§2/§6/§7). Adds the pattern seam
delegating to the built-in RegExp.escape, deletes every hand-rolled
copy, and raises the Node floor to the Active LTS line.

The census was low, three times over. ADR-3212 counted 10 copies; a
graph query found 12; the new lint rule — once live — found 27 more.
The difference is that the census counted named helper FUNCTIONS while
the rule counts the escape SHAPE, so inline .replace(<class>, '\$&')
copies were never in scope. ADR §1's actual requirement is that no
module outside the seam escapes a value for regex use, so all of them
are, and CLAUDE.md's no-defer rule makes them this change's work.
Fourth consecutive epic here whose copy count was low — the argument
for ADR-3180 Amendment 3's "state N found by the guard" rule.

Also corrected mid-implementation: the survey reported phase-id.cts's
escapeRegex had 0 external importers. It had 8 production importers,
making its removal a public-surface change to an ADR-2121-owned module
and requiring an update to that ADR's locked-surface test. Blast
radius revised Medium-High -> High.

RegExp.escape is match-equivalent but NOT text-equivalent: it
hex-escapes the leading char of nearly every string ("abc" ->
"\x61bc"). Equivalence is proven by a seeded fast-check property test
against the deleted implementation as oracle. It also fixes a latent
bug: a hyphen-bearing value interpolated into a character class
previously formed a real range and matched an unintended character.

Node floor 22 -> 24 (RegExp.escape is Node 24+), across engines,
.nvmrc, package-lock, 9 CI matrix entries, and 5 docs. The aggregate
`required-tests` context is unchanged and no job was added or removed,
so branch protection cannot be orphaned by the dropped lanes.

Enforced by eslint-rules/no-adhoc-regex-escape.cjs (shape-matched, with
structural provenance for reviewed pattern-fragment constants rather
than a name heuristic) plus a whole-tree companion guard covering the
directories ESLint's globs miss.

* fix(#3412): close the _SOURCE guard evasion, correct two false claims

Three findings from the orthogonal review pass, all fixed.

1. The ESLint rule's `_SOURCE` provenance fallback was pure identifier-
   name matching with no binding check, so `new RegExp(userInput_SOURCE)`
   — a function parameter — sailed past the guard. That is the same
   rename-evasion class issue #3410 documents, reopened by the very
   fallback meant to complement the structural check. Now bound to the
   identifier's actual binding kind: import, require-derived const, or
   module-scope const; parameters, `let`/`var`, and unresolvable
   bindings fail closed. Four RuleTester cases cover the evasion and
   prove the legitimate cross-module case still passes.

2. src/pattern.cts's own header carried the stale pre-correction counts
   (12 copies / 17 call sites) while CONTEXT.md and the design doc
   carried the corrected ones (~39 / ~44) — a self-contradiction inside
   the PR whose entire purpose is deleting divergent copies. Rewritten,
   preserving the durable lesson: a named-function census cannot see
   inline copies; only a shape-matching guard can.

3. The claim that all deleted copies threw TypeError on non-string was
   false. phase-id.cts's copy — the one with 8 external importers — did
   String(value).replace(...) and never threw. The seam's locked
   signature does not coerce, so this is a real, now-disclosed behavior
   change rather than the pure preservation the tests asserted. Audited
   all 32 invocations across the 8 importers and 6 in-file callers:
   every one is safe by construction (upstream truthy guard or a
   string-producing derivation), verified by runtime probe against the
   compiled modules rather than by TS compilation, which cannot see a
   runtime undefined. Corrected the false claim in both the test comment
   and the design doc, and added it to Known limits.

* docs(#3412): add Changed changeset for the Node 24 floor

The only user-visible break in this phase. The escape-behavior change
is internal and match-equivalent, so it carries no user-facing note.

* fix(#3412): resolve the seam's require graph in script fixtures and packaging

Checkpoint 2 came back red with 90 failures on the node24 lane. Three
distinct defects, all introduced by routing scripts/ through the new
pattern seam, none reproducible by any local gate:

1. ~82 failures — tests/adr-index-gate.test.cjs and
   tests/removed-but-needed-lint.test.cjs copy a scripts/*.cjs into an
   mkdtemp fixture and spawn it there (necessary: those scripts resolve
   their scan root from __dirname/.., so running the real script would
   scan the real repo). Each harness hand-listed the dependencies to
   copy alongside. Adding require('../gsd-core/bin/lib/pattern.cjs') to
   gen-adr-index.cjs made both lists silently incomplete ->
   MODULE_NOT_FOUND, plus 17 downstream 'did not emit parseable JSON'
   failures from the same crash.

   Fixed as a class, not an instance: new tests/helpers/copy-script-
   fixture.cjs walks a script's transitive static relative-require graph
   and copies it, so dependencies are derived and never re-declared. It
   throws (naming the unbuilt artifact) instead of letting the child die
   with a bare MODULE_NOT_FOUND. Verified for all four seam-consuming
   scripts: gen-adr-index, lint-removed-but-needed, gen-loop-host-
   contract, sync-runtime-launcher.

2. 2 failures — scripts/ ships wholesale but eslint-rules/ does not, so
   the new scripts/lint-no-adhoc-regex-escape.cjs would be
   MODULE_NOT_FOUND in a published install (#2858 guard). Excluded from
   the tarball, matching the existing precedent for gen-emitted-
   baseline.cjs, which is excluded for the identical reason, and locked
   with a test modeled on that one. Confirmed against a real npm pack:
   890 files, 0 from eslint-rules/, and gsd-core/bin/lib/pattern.cjs
   present (so the other four scripts' requires are legitimate).

3. 6 failures — tests/phase-id.test.cjs asserted the literal escaped
   source text ('0*29', 'PROJ-42'). RegExp.escape is match-equivalent to
   the retired hand-rolled escaper but NOT text-equivalent: it hex-
   escapes the leading character and all hyphens ('0*\x329',
   '\x50ROJ\x2d42'). Verified NOT a behavior change — 576 match
   decisions across all three real interpolation prefixes, zero
   divergence. Those tests now compile each source into the same heading
   regex src/roadmap.cts's searchPhaseInContent builds and assert what
   matches and what does not, including the 'i'-flag canonicalization
   the hex escape has to preserve. Re-pinning the new literals would
   have rebuilt the same brittleness one layer down. Adds a test for the
   property the escape exists for: a dot in '1.2' must not act as a
   wildcard.

Also shares one definition of 'a require' between the packaging guard
and the fixture copier, so the two cannot disagree about what they scan.

* fix(#3412): refuse to copy a fixture dependency outside the fixture root

copyScriptWithDeps resolved each relative require and joined the
repo-relative result onto fixtureRoot. A require resolving OUTSIDE the
repo yields a '../'-prefixed relative path, so path.join climbed out of
the fixture and wrote into the surrounding temp dir (verified:
repoRoot=/repo + depAbs=/etc/passwd wrote /tmp/etc/passwd).

No script in the tree does this today, so this closes an available
escape rather than an active one. Refuses via the existing unresolved-
require path so the failure names the offending specifier. Covered by a
negative proof that the guard fires and that nothing lands outside the
fixture.

* fix(#3412): parse requires instead of pattern-matching them; restore the foreign-prefix contract

Applies all findings from the second orthogonal review round, re-run
because real code changed after round 1.

HIGH (security) — extractRequires stripped BLOCK comments before LINE
comments, so a '//' comment containing '/*' opened a phantom block
comment, and a '//' inside a string literal truncated the line. Both
hid real requires: 'const u="http://x"; require("./real.cjs")'
returned [], and four real requires in gsd-core/bin/gsd-tools.cjs were
invisible. Replaced with a real AST parse via espree.

This is ADR-3212's own Decision 4 — tokenizer-first for stateful
grammars — applied to the case it describes; comment/string/regex
nesting is exactly such a grammar, which is why the regex version was
wrong. The function was moved byte-identical out of the #2858 packaging
guard, so the bug PRE-DATES this branch and has been a live blind spot
there: a shipped script could have required an unshipped path
undetected. Fixing it makes that guard strictly stronger than on next.

espree is promoted from a transitive eslint dependency to an explicit
devDependency rather than relying on hoisting. The script parse attempt
sets ecmaFeatures.globalReturn because Node wraps CommonJS bodies in a
function, making a top-level return legal — scripts/check-coverage-gate
.cjs relies on it, and without the flag the guard throws on a file it
is supposed to scan. Verified 0 unparseable across all 324 .cjs/.js
under scripts/, bin/, and gsd-core/bin/, and 0 new violations against a
real npm pack, so the exact extractor does not newly fail the guard.

MEDIUM (security) — the repo-containment check guarded dependencies but
not the entry path. One escapesContainment predicate now guards both.

LOW (security) — containment was lexical while fs follows symlinks, and
a directory symlink could mint a fresh dedupe key per level. realpath
now resolves both repoRoot and each dependency before the decision, and
the realpath-derived path is the dedupe key. Destination layout still
uses the original repo-relative path, so copied trees are unchanged.

MAJOR (standards) — the round-1 behavioral rewrite of phase-id tests
lost the foreign-prefix contract: every assertion was satisfied by an
impl returning [A-Z]+\x2d42, i.e. ANY project code — the exact #3599
bug class the exact-source prevents. The literal assertions it replaced
were catching this. Now asserts the compiled regex REJECTS a different
prefix with the same number.

MAJOR (standards) — the test hand-duplicated production's heading regex
with no parity guard (CLAUDE.md's 'Generative Fix Divergence'). Removed
the parallel surface instead of policing it: src/roadmap.cts exports
buildPhaseHeadingRegex, searchPhaseInContent calls it, the test imports
it. Byte-identical .source and .flags verified for both escaped forms.

MINOR — '..foo' no longer false-flagged as an escape; the inverted
spurious-vs-missing doc claim corrected; the dead allow-test-rule
header removed.

* chore(#3412): backfill changeset pr number to 3416

* fix(#3412): make the escape guard's own regex linear, reword an injection-scan collision

Two CI failures on PR #3416, both in code this branch added.

CodeQL js/redos (high) — REPLACE_CALL_RE's outer alternation let a
bracket run be consumed EITHER by the character-class branch OR one
character at a time by the trailing catch-all, so a failing match
explored both parses of every pair. Measured on the real regex:
n=26 -> 204ms, n=28 -> 791ms, n=30 -> 3475ms, a clean 2^n. This script
scans repo source, so a file with a long bracket run after '.replace(/'
would hang CI outright — a guard against undisciplined pattern
construction was itself the worst pattern in the diff.

Fixed the way ADR-3212 already prescribes: the catch-all branch now
excludes '[' and ']' so a bracket can only be consumed by the class
branch (this is what makes it linear), and every quantifier is bounded
(the locked bounded-quantifiers decision) as a second line of defense.
Now 0ms at n=2000. Disclosed coverage tradeoff, recorded at the
constant: a regex literal with a BARE unescaped ']' outside a class is
no longer matched by this backstop. No census shape has that form, and
the AST rule remains the primary detector.

Verified the guard did not go blind doing it: a real census-shape
violation is still reported, and an allow-adhoc-regex-escape
suppression comment is still honored.

Regression test drives the exported findViolations on a
2000-repetition adversarial input and asserts the RESULT. It makes no
wall-clock assertion — elapsed-time tests are forbidden — so a
regression surfaces as a harness timeout, which is the correct signal.

Prompt injection scan — 'must not act as a regex wildcard' in a test
comment matched the scanner's jailbreak pattern act\s+as\s+(a|an|if|
my). Reworded to 'behave as'. Deliberately NOT allowlisted: silencing a
whole test file over one phrase would blunt the scanner permanently,
and the comment has nothing to do with injection.

Neither failure was reachable from the remote runner — CodeQL and the
injection scan are not in that matrix, so the sha it passed was green
and still wrong.

58d73dd220 enhance(#3241): omit the codex per-agent model by default (#3276)
* test(#3241): failing-first suite for the codex passive model posture

Locks ADR-2313's D1-D5 before any production code exists, so the tests
bind to the behavior rather than to whatever the implementation happens
to do.

Red-first (fail against the current tree):
  - the resolver path emits no `model` and no `model_reasoning_effort`
  - a whitespace-only model_overrides value yields no pin
  - isAnthropicFlavoredModel / CLAUDE_AGENT_ALIASES on model-catalog
  - the one-time install notice, and its once-per-install dedupe

Regression guards (pass today, must keep passing): resolver-null via
`inherit` and via absent runtime; a resolver that resolves to nothing;
empty-string and non-string overrides; and the light-tier
service_tier/model_verbosity fields, which are NOT coupled to the model
pin and would silently regress if the implementation coupled them.

Classifying each test as red-first or regression guard is deliberate.
A test that passes on both sides of the change proves nothing, and this
epic has already shipped two such rows before catching them.

The whitespace case is a live defect, not a quirk: `'   '` is truthy,
survives the type guard, is not Anthropic-flavored, and is embedded
verbatim as `model = "   "` — the same class the #2310 guard exists to
stop. Same function, same path, fixed in this phase per CLAUDE.md §3.

Two matrix rows were dropped as vacuous rather than shipped green: a
64-char truncation case (the pinned notice interpolates no
user-controlled value, so it cannot exhibit truncation) and a newline
hazard that the input surface cannot reach.

* feat(#3241): omit the codex per-agent model by default

Implements ADR-2313 D1-D5. generateCodexAgentToml no longer embeds the
runtime resolver's per-tier Codex model, so an agent inherits the
always-available session model instead of a pin a ChatGPT-account Codex
may not expose. model_reasoning_effort disappears with it via the
existing hasPinnedModel coupling (#838) — no logic change needed there.

Supersedes #2517's embedding on the default path only. An explicit
real-Codex model_overrides pin is still embedded verbatim, and the #2310
Anthropic-flavored guard is retained: the model_overrides route to it is
still live even though the resolver route is now unreachable.

The shared rule moves down a layer. CLAUDE_AGENT_ALIASES leaves
model-resolver for model-catalog — a genuine leaf importing only
node:path and its own JSON — with isAnthropicFlavoredModel defined beside
it, and is re-exported from model-resolver so every existing importer is
untouched. This is what lets Phase 2's install-check and Phase 3's sync
consume the rule without taking the config-loader dependency
model-resolver would have dragged into a module documented as pure
read/verify with 33 dependents. A parity test fails if the two ever fork.

Also fixes a live defect surfaced while writing the tests: a
whitespace-only model_overrides value was truthy, survived the type
guard, was not Anthropic-flavored, and so was embedded verbatim as
`model = "   "` — the same class the #2310 guard exists to stop, reached
by a different route. Trimmed before the truthiness test. It is
deliberately not routed through _warnCodexModelOverrideDropped, whose
text would misdescribe a blank field as a mis-typed model.

Adds the one-time install notice (maintainer direction, recorded as an
ADR-2313 amendment): one stderr line naming model_overrides and the
session model, deduped per install rather than per agent, and emitted
only for the population that actually loses a pin.

service_tier and model_verbosity stay decoupled from the model (#774);
a regression guard asserts they still emit with nothing pinned.

* docs(#3241): amend ADR-2313, add the model-catalog glossary entry

ADR-2313 gains two dated amendments rather than edits to its merged
text, since ADRs here are append-only.

The first records that a deprecation notice IS offered, reversing the
Migration section's "no deprecation window" position, and states why
that position was wrong rather than just superseding it: the ADR
identified the API-key population as losing something real and then
declined to warn it, in the same document. Hyrum's guidance was applied
to the recourse and not to the notice.

The second records the whitespace-only model_overrides defect and notes
that D2 always implied the fix — the implementation simply never
enforced it and no test covered the case.

CONTEXT.md gains a Model Catalog Module entry. The module had none,
which is why the glossary gate passed without one: check-glossary-refs
verifies that references resolve, not that modules are documented. The
entry records why the Anthropic-flavored rule lives there rather than in
model-resolver, so a later reader does not "helpfully" move it back. The
Model Resolver entry is updated to point at its new home and note the
back-compat re-export.

docs/CONFIGURATION.md carried a claim that is now false: that the
resolved tier ID is embedded into agent frontmatter at install time on
codex and opencode. Corrected to name codex as the exception, with the
400 symptom and the model_overrides recourse.

Changeset leads with the user-visible change and the migration line
rather than the implementation, per the ADR's Hyrum's-Law analysis.

* fix(#3241): only notice a lost pin when one was actually embeddable

Review finding from an isolated reviewer. The deprecation notice gated
on whether the runtime resolver would have returned *any* model, but the
question that matters is whether that model would have been *embedded*.

Those differ. The #2310 safety gate already rejected an Anthropic-
flavored model arriving from the resolver path before Phase 1 — so for a
mixed-runtime config resolving to a claude-* id against a Codex install
target, the user never had that pin. The notice told them they lost
something they never got, and pointed them at model_overrides for no
reason.

The existing #2310 test drives exactly that path but asserts only the
emitted `model` line, never stderr, which is why it slipped through. Now
covered.

Deliberately unchanged: an Anthropic-flavored model_overrides value plus
a legal resolver model fires BOTH the override warning and the notice.
That is correct — pre-Phase-1 the guard dropped the override, execution
fell through to the resolver, and the resolver's model was embedded, so
that user did lose a pin. Two messages, two distinct true facts, and the
prefixes differ (`gsd: warning — ` vs `gsd: notice — `) so the
one-notice-per-install contract holds. A regression test now pins that
behavior so it does not get "simplified" away.

Of the three tests added, only the first is red-first; the other two
pass on both sides by design and are labelled as guards — one against
over-correcting the fix into silence, one against removing the
intentional double message.

* fix(#3241): reset the notice dedupe via a seam, not a require.cache bust

The remote runner caught a regression I introduced: the #2760
post-write-validation test began failing with the validator override no
longer intercepting.

Cause, confirmed by trace rather than guessed: the new #3241 review
tests deleted require.cache for bin/install.js and re-required it mid
suite, to clear the notice's module-level dedupe flag. But
runCodexInstall destructures `install` at file load, closing over the
ORIGINAL module's exports. After the cache bust a second instance
existed, so the test's `installModule.__codexSchemaValidator = ...`
mutated the new object while the code under test still called the old
one. The override silently stopped intercepting, the real validator ran
and passed on GSD-emitted output, and the abort-and-restore path was
never exercised.

Cache-busting a module mid-suite breaks every later test that assumes a
single instance, which every other test in the file is entitled to. So
the fix is a seam, not a workaround: bin/install.js exports
_resetCodexNoticeDedupeForTests(), and the three tests call it directly
instead of reloading the module.

The flag is module-level by design — the dedupe is per-install and
install() already resets it — so a unit test driving
generateCodexAgentToml directly needs an explicit way to reset it. That
is now what it has.

Swept the rest of the #3241 diff for the same hazard; this flag was the
only shared module-level state introduced.

Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

* fix(#3241): reset both codex dedupe stores, not just the notice flag

Second incomplete fix, same class one layer down. bin/install.js keeps
TWO module-level dedupe stores and the require.cache bust I removed had
been papering over both; my replacement seam cleared only one.

_codexModelOverrideDroppedWarned is a Set keyed `${agent}::${value}`.
tests/codex-config.test.cjs:558 already emits for `gsd-executor::sonnet`,
so by the time the review test using the same agent and value ran,
_warnCodexModelOverrideDropped was a silent no-op and the expected
warning never appeared.

The seam now clears both stores and is renamed to say so. Its comment
records that per-install dedupe lives in module scope deliberately and
that this is the single sanctioned way for a unit test to clear it.

Swept bin/install.js for every other module-scope mutable a test could
latch. Two are inert (capability registries assigned once at require
time; selectedRuntimes computed once from argv). One is a genuine latent
hazard and is deliberately NOT folded in: attributionCache (:1654)
memoizes getCommitAttribution by runtime name for process lifetime, so
two in-process installs of one runtime with differing attribution config
would collide. It is unreachable from any current test and is a
different concern from Codex warning dedupe, so it stays out of this PR
rather than widening it.

* docs(#3241): correct the codex tier-routing how-to

The docs gate forced the task-oriented quadrant and found the worst
defect in this change's documentation surface.

docs/how-to/configure-model-profiles.md carried a section titled "If you
want tiered models on Codex" telling users to set runtime:codex +
model_profile:balanced, promising "GSD resolves each tier alias to the
Codex-native model and reasoning effort defined in the runtime tier
map." That is exactly the behavior this PR removes — a how-to page
confidently instructing users to do something that no longer works,
which is worse than a missing page because it fails at the moment of
use.

Rewritten to state that Codex does no tier routing, give the
model_overrides pin as the supported alternative, and name the two
constraints on what may be pinned: it must be a real Codex model id, and
the account must actually expose it — GSD cannot verify the second, so
the honest advice when unsure is to omit the pin. Carries an upgrade
note for both account types, since the change is a no-op for ChatGPT
accounts and a real loss for API-key ones.

Also tightened the same page's claim that Codex "embeds the resolved
model" at install time — now true only of an explicit override. The
re-install instruction it supports is still correct and still needed, so
only the premise moved.

Both the required-docs set (COMMANDS.md + FEATURES.md) and
lint-docs-required.cjs would have passed before this commit, since
CONFIGURATION.md and the ADR had already moved. Neither checks the
quadrant a user in trouble actually opens.

36f4f9479a fix(#2665): scrub config-location env on raw spawns that sandbox only HOME
Same class as the in-process leak, on the child-spawn side. These call spawnSync
directly rather than through runGsdTools, so TEST_ENV_BASE never applies to them
and an ambient config-location var survives into the child.

  - install-runtime-artifacts: the dev-preferences writer resolved env-first and
    wrote SKILL.md into the live config dir instead of its tmp HOME. This also
    fixes a test that FAILS today on any machine with CLAUDE_CONFIG_DIR set.
  - issue-766: the `claude` CLI is third-party and bootstraps its own config into
    whatever CLAUDE_CONFIG_DIR names, so even a bare --version probe wrote there.
    It gets an explicit throwaway dir rather than a blank value -- GSD's resolvers
    treat '' as falsy and fall back to the home dir, but a third-party binary
    offers no such guarantee (blanking it produced a stray backups/ in the repo
    root).

These two were the last writers standing between the suite and #2665's stated
acceptance criterion.

* fix(#3039): clamp max/xhigh effort to high for Claude-runtime skills

effort: max in plan-phase, execute-phase, and autonomous SKILL.md frontmatter
was passed through as output_config.effort, which the Anthropic API rejects
when extended thinking is disabled (400: effort 'max' is not supported when
thinking is disabled on this model). The frontmatter is static at install
time and the installer cannot know whether thinking will be on or off at
invocation.

normalizeClaudeSkillEffort now clamps both 'max' and 'xhigh' to 'high' —
the maximum value that works in both thinking states on all supported models.

8c1962200d fix(#2911): resolve surface re-stage destinations the way the installer does (#3049)
* fix(#2911): resolve surface re-stage destinations the way the installer does

Two writers computed the same destination differently. The installer honors a
skills-kind home override; the surface re-stage ignored it and always resolved
against configDir. For a global Codex install that override points at
$HOME/.agents, so every re-stage built a second GSD-managed skill tree under
$CODEX_HOME alongside the correct one, with nothing indicating which was live.

Honors the override as a fallback, never a replacement -- runtimes without one
still resolve against configDir, which is most of them.

The real deliverable is the parity test, not the one-expression fix: it walks
every runtime in the registry across both scopes, computes the installer and
surface destinations, and fails naming the runtime if they ever disagree. Today
only Codex global carries an override, so it discriminates on exactly one
runtime -- stating that plainly rather than implying broader coverage -- but it
is derived from the registry, so a newly-added runtime is covered without anyone
remembering to add it.

Two further defects fixed rather than deferred:

- The legacy dev-preferences migration carried the identical defect, which the
  issue flagged as a latent instance of the same shape.
- Fixing it exposed a symlink-escape guard confined against the wrong root: it
  checked the span between configDir and the skill dir, but a home override
  moves the skill dir outside configDir entirely, so the span was meaningless
  and threw a false-positive escape. Now confined against the install root the
  destination actually resolves under. The guard is unchanged in strength and
  still honors its opt-in; only the root it measures from is corrected.

Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

* fix(#2911): honor the home override in the fourth destination writer too

Adversarial review found a writer the fix had missed: the opencode-family skills
installer resolved its destination and its symlink guard against targetDir,
never consulting the skills-kind home override, while its three siblings all
already honored it.

Pre-existing and currently dormant -- it is reachable only for the
combined-family runtimes, and none of them declares an override today, so no
user is affected right now. Fixed anyway rather than left as a latent instance
of the same shape, which is exactly what this issue asked for in the case of the
legacy migration.

Mirrors the shape used for the other three: a single installRoot local that both
the destination and the guard derive from, so the two cannot drift apart. The
guard's message now names the root it actually confined against.

Coverage extended to this writer and proven non-theatre: reverting the change in
a scratch build makes it fail for both combined-family runtimes.

Enumerated every remaining site that computes a destination from destSubpath or
calls the confinement helper -- install and uninstall paths, the surface module,
the read-side skills-root reporter. All honor the override or structurally
cannot express one. No fifth defect. The one adjacent shape, the flat command
directory, reads a different descriptor field that no kind declares an override
for in the current schema; noted rather than papered over with a fallback for a
field that cannot exist.

Verified no behavior change for the affected runtimes today: normalized
file-tree hashes before and after are identical.

628648d63a chore(#2931): cap emitted per-runtime bytes and single-source windsurf (#2984)
* fix(#2931): preserve protected regions and cap emitted per-runtime bytes

Route every runtime brand swap through applyClaudeCodeBrandSwap so
"Claude Code" survives verbatim inside <runtime_compatibility> regions
(#2284b). The fix existed only in bin/install.js's local copies; the
src/*.cts exports still used a naive replace, so binding install.js to
the single source -- as this phase does for the Windsurf family --
would have silently regressed those runtimes. A table-driven parity
guard now covers all nine brand-swapping converters.

De-duplicate the Windsurf converter family: delete the six local copies
in bin/install.js and bind the four exported ones by reference, guarded
by reference-identity assertions (the ADR-1508/#1675 pattern). The two
unexported helpers and an unused tool table go with them.

Replace the Windsurf 12,000-byte throw with description truncation,
matching the bound its sibling skill converter already applied. The
throw could only fire on an ~11.7 KB frontmatter description: the
largest emitted workflow is 311 bytes. Truncation makes the cap
unreachable by construction and leaves 12,000 in exactly one place,
eliminating the dual-surface duplication rather than testing for it.

Add the emitted-byte cap gate: buildEmittedSizes captures LF- and
<HOME>-normalized bytes from the walk buildParityManifest already
performs, and evaluateEmittedCaps asserts them against a per-runtime
cap table with dead-rule detection. buildParityManifest's return shape
is deliberately unchanged -- diffEmitted compares its values with
===, so making them objects would report all 8,529 emitted paths as
moved. A regression test pins the values as strings.

Add a deterministic trim-safety gate over composeWithinBudget's
omitted/shrunk/floored/isolatePrefix metadata, with an anti-vacuity
rule, replacing the model-graded eval gate the issue described.

* docs(#2931): correct ADR-1671 windsurf premise and trim-safety contract

* fix(#2931): bound the windsurf command name and single-source the brand swap

Review findings from the orthogonal passes, all fixed inline.

The claim that removing the 12,000-byte throw left total emission
"bounded by construction" was false. The #1615 regex constrains the
character class but not the length, and commandName is interpolated
three times into the emitted workflow: a 20,000-character name emitted
60,162 bytes silently. Add WINDSURF_COMMAND_NAME_MAX=128 as a separate,
clearly-labelled size control that THROWS -- commandName is the @-ref
path target, so truncating it would point the workflow at a file that
does not exist (DEFECT.WORKFLOW-DELEGATION-TARGET-NOT-INSTALLED). The
#1615 security regex is untouched and still runs first. 128 is generous:
the longest shipped name is gsd-plan-review-convergence at 27.

Harmonize convertClaudeCommandToWindsurfSkill onto the code-point-safe
truncation helper. It still used a UTF-16 slice(0,177) -- the exact
surrogate-splitting bug the helper was written to avoid, in the very
sibling the helper's comment cites as its model. Bounds are unchanged,
so output is byte-identical for every shipped command (descriptions max
out at 99 chars).

Export applyClaudeCodeBrandSwap and bind it in bin/install.js, deleting
the local copy. Adding it to the .cts left two unlinked implementations
of identical logic -- the drift class this change exists to remove.
Verified byte-identical across eight fixtures and five sequential calls
before merging, and guarded by a reference-identity assertion.

Convert three try/finally test bodies to t.after (CONTRIBUTING.md:344),
add fast-check property coverage for the trim-safety contract, and use
fc.pre instead of a bare return in a property callback.

* test(#2931): fix three test-authoring bugs the remote matrix caught

The remote runner returned 8 unique failures on 6f15cdeb8. All three
causes were in the test files, not the modules under test -- local
harnesses exercise the modules directly, so nothing executed the test
bodies until the matrix did.

`{ __proto__: [...] }` in an object literal sets the prototype instead
of an own key, so the JSON round-trip erased it and the cap table never
saw a reserved runtime key. The production rejection was already
correct; the test could not reach it. Use a computed key.

Two cap fixtures tripped orthogonal error paths rather than the paths
they name: one declared windsurf in the cap table but omitted it from
sizes (UNKNOWN_RUNTIME), the other left the sole windsurf pattern
matching nothing (a genuine dead rule). Both now include a compliant
artifact so the intended branch is what is asserted. The dead-rule and
unknown-runtime contracts are deliberate and unchanged.

`const { root } = makeSyntheticConfig({ ... `${root}` })` referenced
`root` from inside its own initializer -- a temporal dead zone error.
makeSyntheticConfig now optionally takes a (root) => files factory.

Also raise the npm pack --dry-run bound 60s -> 120s in the shipped-
scripts packaging test. That failure is NOT from this branch: the file
is byte-identical to next, a fresh tsc measures 1.98s there vs 2.14s
here, and the run recorded 60,637ms against a 60,000ms bound -- a
timeout under 28,948-test parallel contention, not a slowdown. Fixed
rather than deferred because a bound that tight is fragile regardless
of which branch trips it.

88d6b392af fix(#2362): materialize third-party capability skills on opencode/kilo install (#2434)
* fix(#2362): materialize third-party capability skills on opencode/kilo install

installOpencodeFamilyArtifacts/installOpencodeFamilySkills never received
the capability registry, so a registered+surfaced+active third-party
capability skill was silently dropped by the OpenCode/Kilo combined-family
INSTALL path (registry said surfaced:true, disk had nothing). Thread
capabilityRegistry through and reuse the existing #2322 seam's exported
helpers (readInstalledCapabilitySkill, capabilityClusterStems,
CAPABILITY_SKILL_MARKER) to fill in third-party skills after the first-party
loop, with the same guarantees: registry-bound ownership, first-party-wins,
full/'*' sentinel support, and graceful degradation on a missing/corrupt
capability skill.

* test(#2362): cover the tiered (non-'*') profile candidateStems branch

Review found the new third-party capability-skill fill-in for OpenCode/Kilo
had zero coverage of the tiered-profile path — all 12 regression tests only
exercised the '*' full-profile sentinel. Adds a case that resolves a
`standard`-tier profile through a synthetic registry (mirroring the seam's
own __registryFor pattern) and asserts the resulting concrete Set still
materializes the registered capability skill, with its prune-parity marker,
alongside the tier's first-party skills.

Also adds the .changeset/ fragment this fix was still missing.

Extend the #789 CodeBuddy de-dup to Cursor: convertClaudeCommandToCursorSkill (in both src and the live bin/install.js) now emits user-invocable:false, so the skill stays model-invocable while the commands surface is the single '/' entry point.

ed06b6a4b9 fix(#2329): write opencode slash commands to commands/ (plural), migrate legacy command/ (#2354)
* test(#2329): fail-first tests for opencode commands/ (plural) command dir

Red phase, empirically probed: global/local install lands in command/ (singular)
with 71 gsd-*.md files and no commands/; the manifest records 71 keys under
command/ and zero under commands/; all four declaring sites report 'command'.
Migration coverage is black-box (two sequential install runs against one
configDir) so it holds regardless of how the fix implements cleanup.

The Kilo guard passes today by design — a forward-looking no-collateral check.

* fix(#2329): write opencode commands to commands/ (plural), migrate legacy command/

OpenCode discovers slash commands from commands/ (plural); the installer wrote
them to command/ (singular), so none of the ~71 /gsd-* commands appeared in the
TUI. Five sites declared the directory and all had to agree:

- capabilities/opencode/capability.json: both artifactLayout destSubpath entries
  (global + local) and hostBehaviors.flatCommandDir
- bin/install.js: the manifest prefix was a SEPARATE hardcoded 'command/' literal,
  so the manifest would have diverged from the descriptor even after a rename. It
  now derives from _hostBehaviors(runtime).flatCommandDir.
- src/install-engine.cts installOpencodeFamilyArtifacts: the actual write target,
  which bypasses resolveRuntimeArtifactLayout via combinedFamilyInstall. This was
  a fifth site the issue did not list — without it the descriptor change alone
  would not have moved a single file.

Migration: an upgrade over a pre-fix install removes only manifest-proven
GSD-managed files from the legacy command/ dir and rmdirs it once empty.
Unmanifested user files are preserved, never deleted.

Kilo shares the opencode family install path and is explicitly unaffected —
pinned by a no-collateral test.

Note on the tests: the migration cases originally built their legacy fixture by
running the installer and relying on it to produce command/ — i.e. they depended
on the bug to set up the fixture, and became unsatisfiable the moment it was
fixed (block 1 requires command/ to be absent after a fresh install). They now
fabricate the legacy layout explicitly, including rewriting the manifest keys to
the command/ prefix — which is load-bearing, since the migration only removes
manifest-proven files and an unrewritten fixture would silently no-op and pass
even against a broken migration.

* test(#2329): regenerate opencode install golden after rebase onto next

The golden conflicted on rebase because #2322 also regenerated it. Resolved by
regenerating from the merged source rather than hand-merging a generated file;
the only delta is the 71 command/gsd-*.md -> commands/gsd-*.md key renames.

* test(#2329): update stale tests that pinned opencode's singular command/ dir

Seven tests encoded the old contract (opencode: command/gsd-help.md exists, the
descriptor's flatCommandDir, the install-integration contract, and the
resolveRuntimeArtifactLayout golden). They passed in the red phase precisely
because they pinned the buggy singular dir; the fix intentionally changes that
contract, so these are stale-test corrections, not regressions.

Kilo shares the opencode family install path and is deliberately NOT changing —
it stays on command/ (singular). The shared opencode/kilo test is now split via
an explicit per-runtime dir map so the two cannot be conflated, and Kilo's own
layout test is untouched. tests/opencode-command-dir-plural.test.cjs
independently pins Kilo unchanged end-to-end.

* docs(#2329): correct the changeset — do not assert opencode ignores command/

The changeset repeated the issue's stated mechanism ("OpenCode discovers them
from commands/ ... a clean install produced no usable commands in the TUI at
all"). OpenCode's source contradicts that: packages/core/src/v1/config/command.ts
globs {command,commands}/**/*.md, so BOTH names resolve, and its own skill doc
still calls .opencode/command/ typical. Shipping that claim as a release note
would document a mechanism that does not exist.

The change is still right, for the stronger reason: OpenCode's config docs list
plural as the convention and singular as backwards compatibility, so GSD was
shipping on the alias the vendor may withdraw. Reworded to describe it as the
alignment it is, decided on OpenCode's source and docs rather than on bug reports
in either repo.

* fix(#2329): baseline opencode's commands/ surface — closes a data-loss path this PR opened

Not a bookkeeping gap. Moving opencode's command dir to commands/ moved the
install destination to a surface the first-time baseline scan does not cover:
000-first-time-baseline's RUNTIME_SURFACES.opencode lists ['gsd-core','command',
'skills','agents'] — no 'commands'.

installOpencodeFamilyCommands unconditionally unlinks every gsd-*.md under its
destination before writing the fresh set (install-engine.cts:870-873), with zero
manifest or migration involvement. The only thing that protects a pre-existing
file is assertInstallerMigrationsUnblocked, which runs before materialization and
halts when the baseline scan flags an unknown file at a KNOWN surface.

Probed: a pre-existing commands/gsd-plan.md is silently destroyed (install exits
0). The identical file under the legacy, already-baselined command/ surface
correctly halts the install with "installer migration blocked pending user
choice". So this PR would have traded a protected surface for an unprotected one.

Fixed with a NEW fix-forward migration rather than editing 000, per
docs/installer-migrations.md:131-134 — an applied migration never re-runs, so
editing 000 would only protect fresh installs and leave every existing machine
exposed. A new id runs for both populations and drifts no shipped checksum;
adding its entry to EXPECTED_CHECKSUMS is the case that test explicitly sanctions.
All five pre-existing shipped checksums verified byte-identical.

Kilo is excluded by the migration's runtimes filter and keeps command/.

This was previously deferred as a PR-body note claiming "low impact — nothing
else acts on baseline-scan misses". That claim was never probed and was wrong.

185abe2d66 feat(codex): advance Codex/OpenAI model defaults to GPT-5.6 (Sol/Terra/Luna)
Update runtimeTierDefaults.codex and providerPresets.openai in
model-catalog.json to the GPT-5.6 family (gpt-5.6-sol/terra/luna),
advancing from the superseded GPT-5.4/5.5 generation.

Model IDs verified against OpenAI developer API docs:
- gpt-5.6-sol: flagship, /, reasoning xhigh
- gpt-5.6-terra: balanced, .50/, reasoning medium
- gpt-5.6-luna: fast/cheap, /, reasoning medium

Tier mapping is 1:1 (Sol↔flagship, Terra↔balanced, Luna↔fast),
so profile semantics are unchanged — only the underlying IDs advance.

Updates: catalog JSON, test assertions (catalog defaults), docs
(CONFIGURATION.md + zh-CN/pt-BR translations, workflow settings),
and changeset.

16b61d437f test(#2126): resolve review findings — fold dedup, harness fidelity, malformed-parity lock
Adversarial review of the Phase 3 branch surfaced three verified defects; fix
all three in place (no defer):

- install-runtime-artifacts.test.cjs: finish the fold-triplication dedup started
  earlier (only enh-1511 had been collapsed). 11 B1-batch __foldDescribe blocks
  were byte-identical triplicates (~5.9k lines, ~49% of the file), tripling the
  subprocess-spawning installer suites under --test-concurrency — the same
  starvation that produced the temp-dir races this branch fixes. Byte-identity
  verified per block before removal; 230 distinct test/it titles preserved
  (origin/next: 230 -> 230), interleaved B3/B5/B6 singletons untouched.
- config-get-default.test.cjs: make runExpectError faithful to production. The
  throwing process.exit seam was caught by cmdConfigGet's "No config.json"
  guard and reclassified into a spurious 2nd error() with the wrong reason
  (CONFIG_PARSE_FAILED). Drive io.setJsonErrorMode + carry the original message
  on the sentinel so the guard re-throws (single fire), assert exitCount===1,
  and strengthen both probes to assert the typed reason (CONFIG_NO_FILE /
  CONFIG_KEY_NOT_FOUND).
- roadmap.test.cjs: lock the #2121/#2114 malformed_roadmap parity — a
  project-code-prefixed query against a checklist-only roadmap now surfaces the
  same diagnostic a bare query always did (fails on prior silent-empty behavior).

119702ff29 test(#2126): fix os.tmpdir() cross-file race + dedup folds surfaced by gsd-test (no-defer)
Phase 3's gsd-test surfaced 8 pre-existing test-isolation races (in #2090's test
files now on next). Per CLAUDE.md's no-defer rule these are fixed inline in the
current change. Root-caused via /qa-test-architect — all bad-test (the
rewrite-engine production code is race-free):

- install-runtime-artifacts.test.cjs: the "rmSync when readFileSync throws" test
  diffed the SHARED os.tmpdir() for gsd-cmd-rewrites-* dirs and force-deleted any
  new one with no ownership check. Under --test-concurrency it deleted a sibling
  test file's LIVE tempDir mid-copy (the #1575 "ENOENT .../graphify.md") and
  misattributed it as its own leak. Fixed: capture the exact tempDir THIS call
  creates (fs.mkdtempSync monkeypatch, restored in finally) and assert only on
  that — never sweep/delete the shared os.tmpdir(). Also deduped the enh-1511
  block the #1969 consolidation folded in 3x byte-identically (#1970/#1974/#1975)
  down to 1 copy; 308 unique test titles unchanged (verified).
- issue-1575-agent-descriptor-parity.test.cjs: a missing }); nested the M2
  'cursor attribution' test inside the per-runtime loop so it ran 7x (widening
  the tempDir window). Fixed the brace -> runs once as a describe sibling.
- config-get-default.test.cjs: local run()/runRaw() spawned node via
  execFileSync with a fixed 5s timeout and no retry -> ETIMEDOUT under Docker
  load. Redesigned to call cmdConfigGet in-process (fs.writeSync fd-capture +
  process.exit sentinel, both restored in finally) — no subprocess, no wall clock.
- runtime-artifact-conversion.cts: fixed the stale "No production caller today"
  JSDoc on rewriteStagedCommandBodies (real callers: applySurface,
  createRuntimeArtifactInstallPlan) — the false doc invited the bad test.

6e773d97df feat(#2088): migrate Codex onto the Embeddable Orchestration System (ADR-1239)
Drive Codex install/uninstall through the descriptor-driven Host-Integration
Interface (declarative embedding adapter → engine surface dispatch) and fold
every positive `runtime === 'codex'` / `isCodex` projection into descriptor-driven
`runtime.hostBehaviors`. Install/uninstall output stays byte-parity-gated
(tests/fixtures/golden-install-parity/codex.json); no other runtime changes.

Three Context7-verified upgrades, each with a test on the user-reachable surface:
- Skill root → canonical $HOME/.agents/skills via a skills-kind `home` override,
  with pre-move migration cleanup (stale ~/.codex/skills/gsd-* removed on install
  and uninstall; user content preserved). Fixes getGlobalSkillsBase, writeManifest,
  and the skill-manifest inventory to honor the override so --skills-root /
  sync-skills / the manifest report the real location.
- Six new hooks.json lifecycle events (PreToolUse, PermissionRequest, PreCompact,
  PostCompact, SubagentStop, UserPromptSubmit) shared by install + uninstall;
  extendedHookEvents reconciled [] -> the schema-valid wired subset.
- Explicit `[agents] max_depth = 1` in the managed config.toml block, pinning the
  negotiated dispatch.maxDepth:1 axis. validateCodexConfigSchema now permits a
  known-scalar-only bare `[agents]` AgentsToml table (still rejects [[agents]] and
  unknown-key break-forms, #2760); mergeCodexConfig preserves the user's own
  AgentsToml scalars (max_threads etc.) instead of dropping them.

8f2ebbe9bf feat(#1928): remove sunset Gemini CLI runtime, redirect to Antigravity (#1996)
* feat(#1928): remove sunset gemini cli runtime, redirect to antigravity

Google sunset Gemini CLI on 2026-06-18; Antigravity CLI is its official successor (already a first-class GSD runtime). Remove the gemini runtime from the enum (16->15), aliases, labels, config-home fragment, install path, converters (convertClaudeToGemini{Markdown,Toml,Agent}, convertSlashCommandsToGeminiMentions), capability descriptor, gemini-extension.json, RULESET.GEMINI.*, and the interactive menu (renumbered, no gap).

--gemini now prints an explicit deprecation notice citing the 2026-06-18 sunset and redirects to --antigravity (no silent alias, per the issue's Hyrum's-Law rejection). Antigravity is preserved throughout: its GEMINI.md contextFileName, .gemini/antigravity config home, the shared convertGeminiToolName/claudeToGeminiTools tool vocabulary, and the 'gemini' hookEvents dialect it declares. GEMINI.md retargeted as Antigravity's context file.

canonical module suites (runtime-launcher-parity, worktree-safety, install-*, managed-hooks,

Host-env pre-check (per B2): no CLI-receiving host sets a redirecting GSD_WORKSTREAM/GSD_PROJECT
value. One folded suite (bug-3668 runtime resolver) creates an extension-less PATH gsd-tools
stub + bash -c; co-locating it with the host's chmodSync tripped local/no-unguarded-nonportable-exec,
so it's now Windows-guarded (skip on win32) matching the host suite's own bash -c guard.

Regenerates regression-name allowlist (222->182), ratchets file-count allowlist (graphify 7->6,
docs entry removed), makes 26 relocated allow-test-rule exemptions issue-ref-compliant (ADR-456;

../ so it resolves from tests/ root (verified). Host-env pre-check: no CLI-receiving host
sets a redirecting GSD_WORKSTREAM/GSD_PROJECT value.

Regenerates regression-name allowlist (222->205), ratchets file-count allowlist (verify
11->8, validate entry removed), makes 16 relocated allow-test-rule exemptions issue-ref-
compliant (ADR-456; prunes stale ids). Repoints 15 tests/ references across state-md.md
(EN + ja/ko/pt/zh). lint:ci green.

Part of epic #1969. Closes #1974.

85ed50cc4f test(#1972): consolidate 94 command/module regression tests into subject suites
Fold 94 issue-named command/module regression files into the canonical test file
that owns each subject-under-test, across 52 existing suites (state, config, frontmatter,
roadmap-parser, capability-registry, shell-command-projection-dispatch, plan-phase-drift-guard,
health-validation, runtime-converters, commands, etc.). Verbatim block-scoped describe
wrappers; 881 subtests conserved 1:1. No new test files.

Host-env pre-check (per B2): the only GSD_WORKSTREAM/GSD_PROJECT-touching destinations
(intel, planning-workspace) clear those vars hermetically, so folded CLI tests are safe.

Regenerates regression-name allowlist (222->162), ratchets file-count allowlist across
8 buckets (validate entry removed after dropping <=2), makes 34 relocated allow-test-rule
exemptions issue-ref-compliant (ADR-456; prunes 34 stale ids). Repoints CONTEXT.md +
ADR-0002/443/1235/3524 test-file references. lint:ci green.

Part of epic #1969. Closes #1972.

4f779eda43 test(#1970): consolidate 61 install-suite regression tests into function suites
Fold 61 issue-named install/codex/runtime regression files into the canonical
test file that owns each subject-under-test, preserving every assertion and its
origin issue number as provenance (block-scoped describe wrappers, zero assertion
loss — 652 subtests conserved 1:1). Routes:

- codex-config.test.cjs        +19 (codex config/toml/hooks/adapter/skill surface)
- install.test.cjs             +18 (node-runner norm, manifest, arg parse, finishInstall)
- install-runtime-artifacts    +13 (per-runtime conversion + emission)
- install-minimal-hooks        +6  (hook-event dialects + guards)
- path-replacement             +2  (opencode absolute pathPrefix)
- install-write-confinement    +2  (pristine dir writes)
- install-regressions          +1  (user-artifact preservation)

Removes 61 tests/ files → 61 fewer CI processes. Regenerates the regression-name
allowlist (271→222), ratchets the file-count allowlist (config 10→9, install 12→9),
and makes 13 relocated allow-test-rule exemptions issue-ref-compliant (ADR-456;
prunes 13 stale allowlist ids). Repoints ADR-0009's moved-test list. lint:ci green.

Part of epic #1969. Closes #1970.

b307c4cfde refactor(#1734): extract install engine from bin/install.js (ADR-1239 Phase B deep move) (#1735)
* refactor(#1734): extract install engine from bin/install.js (ADR-1239 Phase B deep move)

Relocate the runtime-artifact install cluster out of the 12,490-line
bin/install.js into a dedicated src/install-engine.cts -> install-engine.cjs:
installRuntimeArtifacts, uninstallRuntimeArtifacts, installOpencodeFamilySkills,
and their cluster helpers (_copyStaged, snapshot/restore, legacy migration,
GSD-entry pruning, preserve/restoreUserArtifacts, OpenCode-family converters,
USER_OWNED_ARTIFACTS).

- bin/install.js imports the engine and re-exports the moved symbols for
  back-compat; getCommitAttribution STAYS in install.js (impure config I/O +
  argv explicitConfigDir global) and is injected via a resolveAttribution param.
- 17 test files migrated to import the moved symbols from the engine.
- Bookkeeping: eslint built-artifact ignore, .gitignore, INVENTORY manifest+row,
  CONTEXT.md Install Engine Module glossary seam.

Behaviour-preserving: install output is byte-identical for all 16 runtimes
(golden-parity harness #1730) — the only delta is the new install-engine.cjs
file shipping in the installed gsd-core/bin/lib/ tree.

Closes #1734

527142ad2e fix(#1615): normalize Windows backslash paths in workflow content
computePathPrefix returned a Windows-style path (with backslashes from path.join) into markdown @-references. Workflow file content on Windows ended up with mixed separators, breaking substring checks in install/install-runtime-artifacts tests on windows-latest CI only.

Normalize resolvedTarget and homeDir to forward slashes inside computePathPrefix. The prefix is always substituted into markdown body text, which uses POSIX paths universally. Idempotent on POSIX.

Also normalizes the two test assertions to forward-slash form so they pass on Windows. Adds a regression test for backslash-style input.

Documents DEFECT.WINDOWS-PATH-LEAK-IN-MARKDOWN-CONTENT + RULESET.CONTENT-PATH-NORMALIZATION in CONTEXT.md so this anti-pattern stops recurring.
