54085516c1 fix(#4211): materialize Kimi's agent tree recursively during surface apply (#4371)
* fix(#4211): materialize Kimi's agent tree recursively during surface apply

kimiAgentsKind stages `gsd.yaml` + `gsd.md` + `subagents/gsd-*.{yaml,md}`, and
install copies that tree recursively (_copyStaged). Surface apply fell through
to _syncGsdDir's flat command/agent branch, which reads only top-level `*.md`:
the YAML half and the whole subagents/ subtree were ignored, and `gsd.md` was
written as `gsdgsd.md` because the flat branch re-applies kind.prefix to a name
that already carries it. A surface change could therefore corrupt Kimi's
installed artifacts while still reporting success.

Three divergences from the install path, all in src/surface.cts:

- _syncGsdDir gains a kimi-agents branch: recursive copy, then a prune scoped
  to exactly what install's _removeGsdEntries owns for this kind (the two root
  files, and gsd-*.{yaml,md} under subagents/). Everything else is user-owned
  and preserved.
- applySurface stages kimi-agents WITH agentCtx and the `skills: '*'` rule for
  an unmodified full profile, as it already does for the agents kind and as
  createRuntimeArtifactInstallPlan does for every kind — without it Kimi's
  generated subagents lost their path-prefix rewrites and attribution trailer,
  and an unmodified full profile staged only the skill-referenced subset.
- applySurface runs rewriteStagedSkillBodies for kimi-agents, which the
  install plan routes through it alongside skills.

* chore: add changeset for #4211

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.

* 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.

* 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.

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.

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

* 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.

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

* 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
call tree; the stricter adapter is what exposed them.

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

* 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.

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

* 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.

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

* 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.

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

* 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.

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

* 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.

cf6de5e1c0 feat(#2871): resolve triggers and host precedence, not just placement (#3291)
* test(#2871): failing-first suite for trigger-surface resolution

23 tests over the 50-test-matrix rows. RED by construction:
resolveTriggerSurface and DEFAULT_TRIGGER_PRECEDENCE do not exist yet,
and the validator silently ignores triggerPrecedence today.

Written in the per-runtime describe idiom the other four
runtime-artifact-layout suites use, not a table.

The rows that carry the weight: windsurf must NOT report a shadow it
does not have, since its global scope emits only agents and agents are
not trigger-bearing; agents and kimi-agents must be absent from the
output for every runtime; and reordering a runtime's triggerPrecedence
must flip the winner, which is the only assertion that proves the axis
is read rather than decorative.

Stems are injected, never scanned, so the surface is assertable with no
filesystem.

* feat(#2871): resolve triggers and host precedence, not just placement

resolveTriggerSurface(runtime, scopes) returns every /gsd-<name> trigger
a runtime emits, with the scope and kind that produced it, whether the
host registers it directly or only through a router, and which artifact
shadows it. resolveRuntimeArtifactLayout is untouched -- its 7 callers
need placement only and the issue requires them unchanged.

AGENTS ARE NOT TRIGGER-BEARING, and ADR-2866 said they were. The
host-integration matrix models command and dispatch as separate interface
points: an agent is invoked through the Agent tool's subagent_type, not
by typing a slash trigger, and _copyStaged never applies the kind prefix
to an agents entry. So agents and kimi-agents are excluded from the
surface entirely, and this commit amends ADR-2866 with a dated
correction. #2218's conclusion is unchanged -- the collision is strictly
commands-vs-skills, and claude's local /gsd-* trigger surface is still
fully shadowed -- but the ADR implied the local agents surface was lost
too, and it is not.

That correction is what makes windsurf come out right. Its global scope
emits only agents, so it has no global trigger and its local commands
are unshadowed. Model agents as trigger-bearing and windsurf falsely
reports a full shadow.

The triggerPrecedence axis lands on all 19 descriptors as an ordered
kind list, one value with one owner, rather than a numeric rank spread
across N kind entries with nothing keeping them consistent. Validation
uses a required-with-default shape that has no precedent in this
validator -- every existing axis is hard-required -- so a third-party
capability.json omitting the field still validates, which is what
ADR-894's additive-only contract promises.

Winner resolution reads Phase 1's scope rank first, then the kind
ordering. A test reorders the axis and asserts the winner flips, since
an axis that is added, validated and never consulted would pass every
other assertion.

shadowedBy ships unread. Phase 4 (#2873) is its first consumer, per this
issue's out-of-scope note.

Verified via the remote runner.

* fix(#2871): single-source namespacedByDir and close two test gaps

Four findings from the isolated adversarial review.

The namespacedByDir rule had reached three copies -- install-engine,
surface, and the new trigger resolver -- one of which carried a
hand-written keep-in-sync comment and no assertion. That is this repo's
generative-fix-divergence class. Extracted to one exported predicate all
three now call. Verified by diverging one copy deliberately: the existing
#816 parity test failed, and passes again on revert.

The omission test was vacuous. Row 16 asserted that a descriptor without
triggerPrecedence still validates, but built its fixture from claude's
shipped descriptor -- which this PR had just added the axis to. It now
clones and deletes the key, following the shippedDescriptorWithout
pattern, and asserts both that validation passes and that the resolver
still picks the right winner from the default. The second half is what
makes it prove anything.

resolveTriggerSurface silently dropped an unrecognized scope while every
sibling in this epic throws. Two phases of one epic should not disagree
about whether an invalid scope is an error, so it now rejects through the
same shared validator; an empty scope list still returns empty rather
than throwing.

The ADR amendment had been spliced into the middle of the References
list, orphaning its last bullet. Moved to the top, after the header
block, which is where ADR-3660 and ADR-1016 both put dated amendments.
No lint checks markdown structure, so this was green while malformed.

* fix(#2871): single-source the command filename composition too

The earlier fix shared the namespacedByDir boolean but left the
filename composition around it written twice -- once in _copyStaged as
what actually gets written, once in resolveTriggerSurface as what gets
predicted. The predictor could go stale silently.

One exported helper now composes it for both. The entry.name asymmetry
that looked like it would block extraction does not: entry.name is
filtered to end in .md and stem is entry.name minus those three
characters, so the two branches are the same string by construction.

Divergence proven to fail: injecting a marker into the helper broke the
trigger-surface suite; reverting restored 25/25. The four sibling layout
suites hold at 227 unchanged.

* docs(#2871): correct the ADR timing notes that this phase makes stale

The Amended by back-links on ADR-3660 and ADR-1016 were written in
Phase 0, when the widenings they describe had not shipped. Each carried
a forward-looking clause -- "the module changes at Phase 2, not before,
until then this module resolves placement only" -- which becomes false
the moment this PR merges. ADR-2866's own Amends header and its
reciprocal-notes section carried the same tense.

All four now describe what shipped. This is a tense and status
correction on Accepted ADRs, not a change to any decision.

Worth stating because it is the failure mode this epic keeps meeting:
gen-adr-index.cjs tracks only Supersedes and Subsumes, so nothing in CI
would have caught either the missing back-link in Phase 0 or these stale
clauses now. They stay correct only because someone checks.

c2f24265f2 feat(#2870): resolve install scope as a value (#3278)
* test(#2870): failing-first suite for the Install Scope Module

19 tests over the 50-test-matrix rows 1-19. RED by construction: the
module under test does not exist yet, so the suite fails at require with
MODULE_NOT_FOUND until src/install-scope.cts lands.

Every row asserts a returned value with injected env/home/existsSync --
no filesystem, per the issue's acceptance criterion that tests assert the
resolved value directly.

Row 7 asserts the RELATION rank(global) > rank(local) rather than a
literal, so Phase 2 (#2871) can re-base the numbers without a fixture
edit. Row 4 iterates the real runtime registry rather than a hardcoded
list, excluding vscode, which declares configHome.kind none and is never
CLI-installed.

* feat(#2870): add the Install Scope Module

Scope becomes one resolved value instead of a bare string re-derived at
every layer. resolveScope({id, runtime, ...}) returns
{id, configHome, settingsFile, consentRequired, hostPrecedenceRank}.

It COMPOSES resolveConfigHomeFromDescriptor rather than extending it.
That function has 60 dependents across 13 files and 2 process flows -- a
CRITICAL blast radius -- so adding a scope parameter to it, which the
issue's framing invites, would ripple through all of them. Composing
costs nothing and leaves every existing caller byte-identical.

The module owns the InstallScope type name, which previously lived
privately in runtime-artifact-install-plan.cts; that module now imports
it. A fifth spelling of the same concept would have defeated the phase.

settingsFile is null for the 18 runtimes that declare no
settingsFileByScope -- absence is a value, not an error, and inventing a
Claude-shaped default would leak that host's shape onto every other one.

hostPrecedenceRank ships unread: Phase 2 (#2871) is its first consumer.
It is carried as data only, per this issue's out-of-scope note that
precedence semantics belong to that phase.

Vocabulary: the install axis standardizes on local. ConsentRecord.scope
keeps project deliberately -- that literal is serialized into consent
records in the user's home, and renaming it would silently deactivate
every project-scoped capability on the machine. CONTEXT.md records the
boundary mapping instead.

Every environmental input is injectable (env, home, existsSync, cwd), so
the resolved value is assertable with no filesystem at all.

Registration ripple: .gitignore, eslint.config.mjs, CONTEXT.md glossary,
docs/INVENTORY.md, and the inventory manifest (regenerated after
build:lib, never before).

Verified via the remote runner.

* refactor(#2870): route scope re-derivations through the module

bin/install.js resolves scope once per function instead of inline at
each of its 12 sites, and the settingsFileByScope consumer reads it
through resolveScope().

Seven downstream boolean re-derivations now call the module's
isGlobalScope() instead of comparing the literal independently:
runtime-artifact-install-plan, both runtime-artifact-layout kind
builders, dispatchKindEntry, surface, and two install-engine sites. The
fifth through seventh were not named in the issue -- they are the same
re-derivation class, and leaving them would have made the acceptance
criterion false.

_computePathPrefix keeps its isGlobal boolean API, so the projection is
centralized rather than eliminated. resolveScope and isGlobalScope share
one validator, so the two surfaces cannot drift.

TWO SITES DELIBERATELY NOT ROUTED: runtime-artifact-conversion's
rewriteStagedSkillBodies and rewriteStagedCommandBodies. ADR-1508 fixes
the direction as installer/layout -> conversion, never upward, and
install-scope composes runtime-homes, so importing it into the
conversion module would invert that direction. Left as-is on purpose.

Behavior-preserving throughout. Each step was proven by capturing full
layout and plan output -- including every kind's home field and the
hashed contents of emitted files -- before and after, across both scopes
for claude, codex, opencode, hermes, kimi and kilo. Byte-identical.

surface.cts keeps a scope ?? 'global' default before the call because
Layout.scope is optional there; isGlobalScope throws where the old
inline compare returned false, and that difference would have been a
placement regression.

Verified via the remote runner.

* fix(#2870): cover the no-config-home throw and document the strictness

Two findings from the isolated adversarial review.

The vscode case was implemented but untested. resolveScope throws for a
runtime whose descriptor declares configHome.kind 'none', which is the
design's own behavior-table row 13, but the registry sweep excluded
vscode rather than asserting the throw -- so the behavior shipped with
no test. The exclusion is now legitimate because the case has its own
test naming the runtime in the assertion.

isGlobalScope throws where the inline compare it replaced returned
false. No reachable caller can deliver an out-of-union value today, but
the types are not enforced at runtime, so a future caller passing an
optional Layout.scope would crash rather than silently misroute. That is
the better failure -- misrouting writes artifacts to the wrong place --
but it was undocumented, so the reason is now on the function.

Adds the changeset the acceptance criteria require.

* refactor(#2870): route the last two sites; correct the ADR-1508 claim

The previous commit declined to route runtime-artifact-conversion's
rewriteStagedSkillBodies and rewriteStagedCommandBodies, claiming
ADR-1508's dependency direction forbade the import. That reasoning was
wrong, and this commit corrects it.

Two independent reviewers checked the actual import graph:
runtime-artifact-conversion already imports capability-registry,
command-roster, runtime-name-policy and shell-command-projection -- it
depends on leaf-tier siblings today. install-scope imports only
runtime-homes plus node builtins, and runtime-homes imports only node
builtins, so there is no cycle at any depth. ADR-1508 governs the
installer/layout to conversion boundary, not a leaf-to-leaf sibling
import of the same shape conversion already makes.

With those two routed, every isGlobal re-derivation in the tree now goes
through one owner and acceptance criterion 1 is fully met rather than
partially. Nine sites, not the four the issue enumerated.

Also from the review:

Tests were falling through to the real process.cwd() at five local-scope
call sites, which contradicts the acceptance criterion that the resolved
value be assertable with no filesystem. Every one now injects a cwd. One
of the five was a site the review had not spotted.

bin/install.js carried two near-identical copies of the guarded
resolveScope block, one in install() and one in uninstall() -- duplicated
scope logic in the phase whose purpose is removing it. Extracted to one
helper, and the new sites use the file's existing ternary idiom rather
than the if/else that replaced it.

Equivalence re-proven across both scopes for claude, codex, opencode,
kilo and hermes, now including the staged skill and command body
rewrites hashed per file, since those decide the literal spec-root path
baked into every emitted artifact. Byte-identical.

Verified via the remote runner.

* fix(#2870): assert configHome portably instead of with a native separator

The windows-latest node24 shard failed on two install-scope assertions.
The module was right and the tests were wrong: they built their expected
value with path.join, which emits \fake\home\.claude on Windows, while
resolveScope normalizes separators unconditionally to /fake/home/.claude.

That unconditional normalization is deliberate -- backslash paths arrive
on Linux too, so normalizing via path.sep is the documented defect this
repo guards against. Weakening it to make the assertion pass would have
inverted the fix.

Every path.join-built expectation in the suite now goes through
toPosixPath from tests/helpers.cjs, which is the pattern the
no-path-literal-in-assert rule's own valid-case list sanctions. It splits
on the running platform's path.sep and rejoins with forward slashes, so
it reverses whatever path.join produced on that same platform and the
expectation is invariant everywhere.

Two more call sites had the same latent problem and passed on Linux and
macOS by luck; they are fixed too.

This is the class of defect the remote runner structurally cannot catch
-- its matrix is Linux-only, so a green pass there is not evidence of
portability, and CI's Windows lane is the only place it surfaces.

Verified via the remote runner.

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.

23a65c4a3d fix(#2322): materialize installed third-party capability skills (#2340)
* test(#2322): fail-first tests for third-party capability skill materialization

Red phase: tests (1) and (6) fail — resolveSurface reports the third-party stem
surfaced (#2045) but no SKILL.md is ever written to disk. The other four are
controls that must keep holding: first-party-wins collision, profile-tier filter,
nested-router layout unperturbed, and absent/malformed capability must not throw.

* fix(#2322): materialize installed third-party capability skills

A capability could report installed:true, surfaced:true, active:true and still
never exist as an invocable command. #2045 fixed the registry layer —
resolveSurface unions registry.capabilityClusters into the resolved skill set —
but the materialization layer never got the matching fix.
stageSkillsForRuntimeAsSkills only ever read gsd-core's own bundled
commands/gsd/*.md and silently skipped any stem it couldn't find there, so a
third-party skill living at <GSD_HOME>/.gsd/capabilities/<id>/skills/<stem>/
was never copied. Registry said surfaced; disk had nothing.

Installed capability skills are now staged alongside the first-party ones, copied
verbatim (they are authored complete for their target runtime and need no
converter). First-party stems always win a collision, the profile filter still
applies, and an absent or malformed capability degrades rather than throwing.

Security: capability.json's skills[] entries are validated only as non-empty
non-reserved strings (capability-validator.cjs:503-514) — no path shape is
enforced upstream — so stems are sanitized (rejecting separators, '..', absolute
paths, NUL) with an independent isPathConfined check on both the read and write
paths. A '../../evil' stem writes nothing outside the capability's own dir.

Also fixes a defect this surfaced in pruneSkillDirs: a materialized capability
skill dir has no first-party manifest entry, so every apply logged
"preserving (user-owned or unknown)" for a live GSD-managed dir. The retained
check now precedes the manifest gate; no deletion outcome changes, and genuinely
unknown gsd-* dirs still warn and are preserved.

* fix(#2322): address security review — bind skills to declaring capability, fix full profile

An independent security review BLOCKED the first pass. Both blockers were mine.

BLOCKER 1 (security): readInstalledCapabilitySkill scanned every capability dir
and returned the first sorted match, never checking that a capability DECLARES
the stem — ownership was inferred from attacker-controlled filesystem layout.
Since install copies the whole bundle and the validator only checks DECLARED
entries, a capability declaring `skills: []` could ship an undeclared
skills/deploy/SKILL.md and win the `deploy` stem on sort order, supplying the
agent-invocable instructions the user believed came from the registered
capability. Stems are now bound to their owning capId via
registry.capabilityClusters, and only that capability's dir is read.

BLOCKER 2: the fill-in pass was gated `skills !== '*'` on the premise that
applySurface materializes `full` into a concrete Set. True for applySurface —
false for the installer, which is the default path: resolveProfile returns the
'*' sentinel and bin/install.js passes it straight to staging. So #2322 survived
on the default `full` profile, i.e. the fix didn't fix the reported bug. The
registry is now plumbed to staging, and '*' stages all capability-cluster stems.
Wiring this surfaced a second gap: the ADR-1239 imperative adapter (the primary
install path) never threaded its registry either, which would have silently
defeated the fix on the real default install.

HIGH: staged capability skills were never prunable — pruneSkillDirs gates on the
first-party manifest, so uninstalling a capability left its instructions live in
the agent's context forever. Staged skills now carry a marker making them
GSD-owned and prunable; genuinely unknown gsd-* dirs still warn and are preserved.

MEDIUM: the "staged verbatim" claim was false — applySurface rewrites bodies over
the whole stage dir. The tests asserted byte-equality and passed only because
their fixtures contained no rewrite triggers. Claim dropped; tests now assert the
rewrite against triggering content.

LOW: isPathConfined is lexical, not realpath (symlink-defeatable, currently
unreachable because install rejects symlinks) — comment corrected. The validator
does not enforce non-empty, so isSafeCapabilitySkillStem is the sole defense, not
a second layer — comment corrected and it now has traversal/NUL/absolute/empty
test coverage (previously mutating it to `return true` left every test green).

* test(#2322): pin that the imperative adapter forwards a capability registry

The delegation-args test deep-equalled the exact argv to
installRuntimeArtifacts, so threading the composed capability registry through
the ADR-1239 imperative adapter (required for #2322 — without it the default
`full` install path never materializes third-party capability skills) failed it.

The contract legitimately gained a parameter, so this is a stale-test
correction, not a regression. Rather than deep-equalling the whole composed
registry (brittle — it embeds the full agent/profile map), the test pins the
leading args exactly and asserts only that a registry-shaped value is forwarded.
That still fails if the adapter stops threading it, which is the regression the
test exists to catch.

e0f969af6a refactor(#2246): centralize cross-platform path-separator handling (toPosixPath / toNativePath / posixNormalize) (#2247)
Replace every open-coded separator translation across the installer/hooks
source with named, tested seams in shell-command-projection.cts (the platform
seam), removing all hardcoded `/`+`\` from path handling:

- toPosixPath(p)   — this machine's native path → POSIX (running-OS relative;
                     for local filesystem paths).
- toNativePath(p)  — POSIX → native (collapses the win32 `/\//g,'\\'` ternary).
- posixNormalize(p)— unconditional `\`→`/`, OS-independent; for emitting paths
                     to a POSIX/bash TARGET (which may differ from the running
                     OS) and for parsing mixed-separator input.

core-utils.toPosixPath now delegates to the seam, so its 20+ existing consumers
resolve to one implementation; no duplicate helper.

- ~47 sites across runtime-hooks-surface, runtime-artifact-conversion,
  runtime-artifact-install-plan, drift, init, worktree-safety,
  installer-migrations, installer-migration-authoring, install-engine, surface,
  verify, runtime-artifact-layout, schema-detect, check-command-router.
- Closes the latent POSIX-literal-backslash corruption class (the regex form
  corrupts a POSIX path containing a literal backslash; split(path.sep) does not).
- New unit + fast-check property tests for all three helpers.

Closes #2246

d1e9491fef feat(#2099): drive GitHub Copilot through the EoS descriptor + multi-event hook bus (ADR-1239)
Fold Copilot's residual runtime-literal branches onto descriptor-driven
hostBehaviors. Several issue premises were inaccurate (verified via research)
and deliberately NOT followed: writesSharedSettings/"legacy exclusion list"
(per-runtime descriptor data, copilot's false is correct); RUNTIME_CONTENT_DISPATCH.copilot
+ installSurface==='copilot-instructions' (already descriptor-driven);
extendedHookEvents (closed Claude/Gemini enum — hooks extended in code instead);
reapply ternary (already folded, kimi #2095).

Real folds (all byte-parity — golden byte-identical for every runtime):
- src/install-engine.cts + src/surface.cts: the two `.agent.md` filename cutovers
  (_copyStaged + _syncGsdDir) unified onto hostBehaviors.agentFileExtension via a
  new exported agentFileExtensionFor() accessor (kills the two-mechanism divergence).
- src/runtime-artifact-conversion.cts: applyAgentPathRewrites' copilot skip →
  hostBehaviors.noPathRewrite:true (antigravity #2096 precedent).
- bin/install.js uninstall: the two isCopilot cleanup branches → installSurface===
  'copilot-instructions' gate (symmetric with install-time).
- bin/install.js: `!isCopilot` in the two skipSharedHooksInstall checks →
  hostBehaviors.skipSharedHooksInstall:true (copilot has no shared gsd-*.js hooks).
- bin/install.js: three dead legacy inline-agent-loop isCopilot refs removed
  (copilot ∈ _DESCRIPTOR_AGENTS_RUNTIMES → unreachable; byte-parity proven by clean
  golden + real reachable-runtime install diffs). isCopilot dropped from 4 destructures.
Zero live `runtime==='copilot'`/`isCopilot` branches remain in bin/install.js,
install-engine.cts, surface.cts, or runtime-artifact-conversion.cts (AC2 guard scans all four).

UPGRADE 1 (multi-event hook bus): buildCopilotHookConfig() now emits preToolUse/
postToolUse/userPromptSubmitted/sessionEnd advisory handlers alongside sessionStart
(static inline bash/powershell — deterministic, golden-trackable). Only copilot.json's
gsd-session.json hash changes.

UPGRADE 2 (background dispatch): surfaced via the negotiated contract only —
dispatch.background:true exceeds the declarative-cli baseline and survives negotiation
with no downgrade warning. NO .agent.md frontmatter field (copilot has none). MCP
companion out of scope (AC4 names only 2 upgrades).

Tests: declarative-reference-copilot (adapter/axes/fail-closed + AC2 4-file source-grep
guard) + copilot-upgrades (live 5-event hook wiring; dispatch.background negotiation).
Matrix EoS note + how-to; changeset (Changed). capability-registry regenerated.

Incidental flaky-test RE-ARCHITECTURE (no-defer, maintainer-directed):
tests/opencode-review-reconstruction.property.test.cjs spawned ~600 synchronous
execFileSync('jq') subprocesses (numRuns:200 × 3 fast-check properties, one jq per
generated stream); a single jq freezing on a contended macos-22 CI runner hung the whole
unit-test chunk to its 600s kill (this PR's CI). --test-force-exit can't interrupt a
synchronous execFileSync, so the cure is to stop spawning per case, not just time-bound
it. Re-architected to run the SHIPPED jq program over the whole fast-check corpus in ONE
jq process: each generated stream is one compact-JSON array per line in a temp file,
`jq -c <PROGRAM>` (no -s) applies PROGRAM to each array (`.` == the array, exactly what
production's `jq -rs <file>` sees after slurping) and emits one result per line —
empirically byte-identical to the per-stream form across embedded-newline/empty/quote/
unicode/null-drop cases, and file-input (like production) so there's no stdin pipe to
deadlock on large I/O. ~600 spawns → 6; coverage unchanged (200-case corpus per property,
deterministic seeds) plus explicit boundary/diagnostic example batches. Still property-
tests the real shipped jq (no JS reimplementation). Per-call jq timeout retained as a
belt-and-suspenders bound.

847de596b8 fix: third-party capability skills surface correctly (#2045)
A skills-only role:feature third-party capability installed 'active' but its skills never reached the runtime surface, capability enable/set rejected it as 'unknown capability', and capability list disagreed with capability state. Three defects, fix shape 1b (teach resolveSurface, no on-disk linking):

D1 (materialization): resolveSurface built the surfaced skills Set only from the on-disk manifest; third-party cap skills live at ~/.gsd/capabilities/<id>/skills/ and never entered the Set -> surfaced:false. Fix: union registry.capabilityClusters values into the Set in the full-profile branch (idempotent for first-party, additive for third-party; prototype-pollution guarded).

D2 (enable/set unknown): setCapabilityState validated the capId against the static first-party registry instead of the composed overlay-aware registry. Fix: validate against loadRegistry({includeInstalled}) like capability-state.cts does.

D3 (list vs state): capability list derived status purely from ledger existence, never surface composition. Fix: add a 'surfaced' field to list rows sourced from the same resolver capability state uses, so list and state agree.

Regression coverage: tests/issue-2045-third-party-skills-surface.test.cjs asserts all five acceptance criteria (resolveSurface union, state surfaced:true, enable/set not-unknown, list/state agreement, first-party + unknown-id regression). gsd-test: 23916/23916 green (linux-node22 + linux-node24).

d671171698 feat(#1575): complete agent-converter descriptor cutover for copilot/antigravity + surface path parity
- Teach applySurface to build agentCtx (pathPrefix + attribution) and pass it
  to kind.stage() for agents kind, mirroring createRuntimeArtifactInstallPlan
  (ADR-1235 §1). Surface-path agents now receive path-rewrite + attribution +
  converter + normalize, matching install output byte-for-byte.

- Pass skills:'*' sentinel for agents staging when no surface state modifications
  exist, so ALL agents are staged (not just those referenced by _calls_agents_).

- Declare converted agents kind in copilot and antigravity capability.json;
  add to _DESCRIPTOR_AGENTS_RUNTIMES in bin/install.js.

- Handle copilot .agent.md filename rename in both _copyStaged (install path)
  and _syncGsdDir (surface path).

- Ship golden-parity harness (ADR-1235 §0): tests/issue-1575-agent-descriptor-
  parity.test.cjs asserts applySurface output is byte-identical to
  installRuntimeArtifacts for all 7 descriptor-driven runtimes, plus stale-
  cleanup convergence and prune data-loss coverage.

460956bfed fix(#2018): applySurface empty manifest no longer deletes gsd-* agents (#2031)
* fix(#2018): applySurface empty manifest no longer deletes gsd-* agents

The agent-prune loop in _syncGsdDir deleted any gsd-*.md not in the staged
set. When the manifest resolved empty (null/non-object, no entries, no files
key, or unresolvable install source root), the staged set was empty → every
gsd-* agent was deleted. Skills were guarded by pruneSkillDirs' manifest-
membership check; agents had no equivalent.

- src/surface.cts: skip the agent-prune loop when the manifest is empty/absent
  (copy still runs — genuinely new agents are added).
- tests/surface-empty-manifest-agents.test.cjs: boundary matrix — empty
  manifest preserves agents (Map() + undefined); non-empty manifest + empty
  staged still prunes (boundary); empty manifest + new staged copies new +

658ea33cb6 fix(#1615): applySurface rewrites commands kind, not just skills
Codex adversarial orthogonal review of PR #1622 surfaced that applySurface (src/surface.cts) only called rewriteStagedSkillBodies for kind='skills', skipping kind='commands'. The gap meant /gsd-surface profile changes on any runtime with commands kinds (windsurf, opencode, kilo, cursor, augment, codebuddy, gemini) wrote raw @~/.claude/... references into synced command/workflow bodies, which fail at invocation time on non-Claude runtimes.

For Windsurf specifically, this left workflow files containing @~/.claude/gsd-core/commands/gsd/X.md after a profile change — paths that don't exist on a Windsurf install. Verified by the new regression test which fails before the fix (workflow bodies contained @~/.claude/) and passes after (workflow bodies reference the install target).

Captures the return value of rewriteStagedCommandBodies (temp dir path — commands rewrite uses copy-then-rewrite to avoid mutating the package source), syncs from the temp dir, then cleans up. Type annotations satisfy typescript-eslint strict mode.

Findings 2 (install ordering) and 3 (legacy .devin cleanup) from the same review are tracked in #1629 — both real but out of scope for #1615.

eb81faaeab refactor(#1511): move content-rewrite engine to conversion module, delete the install.js relay (#1513)
* refactor(#1511): move content-rewrite engine to conversion module, delete the install.js relay

Phase 2 of epic #1507 (ADR-1508). Behavior-preserving: makes the Runtime
Artifact Conversion Module the single owner of per-runtime content rewriting and
removes the last upward .cts -> bin/install.js dependency.

- src/runtime-artifact-conversion.cts now owns the engine (_applyRuntimeRewrites,
  5-arg with INJECTED attribution), the staged-content walkers
  (applyRuntimeContentRewritesInPlace / ...ForCommandsInPlace), computePathPrefix
  (private, exported as _computePathPrefix for tests), and the deep public seam
  rewriteStagedSkillBodies / rewriteStagedCommandBodies({runtime, configDir,
  scope, homedir?, platform?, resolveAttribution?}).
- src/surface.cts:applySurface calls rewriteStagedSkillBodies directly (no
  resolveAttribution -> undefined). Co-Authored-By is absent from ALL rewritten
  content, so processAttribution is vacuous there and undefined is provably
  behavior-identical. surface no longer imports getInstallExports.
- src/runtime-artifact-layout.cts: deleted getInstallExports / loadInstallExports
  / InstallExports + the GSD_TEST_MODE require('bin/install.js') relay.
- bin/install.js: binds computePathPrefix / the two walkers / _applyRuntimeRewrites
  from the conversion module (single implementation, exports preserved for Hyrum);
  install callsites pass getCommitAttribution(runtime) as the injected attribution.
  getCommitAttribution stays here (impure install-time config I/O).
- DEFECT.GENERATIVE-FIX guard: tests assert install.X === conversion.X reference
  identity for computePathPrefix + both walkers (no drift).

* test(#1511): make rewrite-engine path assertions Windows-robust

The deep seam normalizes paths as path.resolve(configDir).replace(/\\/g,'/')
and compares homedir().replace(/\\/g,'/'). Three assertions in the new test
rebuilt expected paths without that normalization, so they passed on Mac/Linux
but failed on Windows CI (PR #1513):

- two absolute-branch asserts rebuilt resolvedTarget via path.resolve(configDir)
  without the backslash→slash replace → mismatch on Windows.
- the $HOME-branch test fed a POSIX-literal /home/testuser, which Windows
  path.resolve re-roots onto the cwd drive (D:/home/...), so the
  resolvedTarget.startsWith(homeDir) check failed and the $HOME shorthand was
  never produced.

Fix is test-only (engine unchanged, still behavior-preserving): mirror the
engine's .replace(/\\/g,'/') in the two absolute-branch asserts, and use a real
absolute path (path.resolve(os.tmpdir(), ...)) + platform: process.platform for
the $HOME-branch test so the comparison holds on all platforms.

dc139b38e0 feat(#949): install/surface consume derived profiles/clusters (ADR-857 phase 4c) (#954)
Make install + surface read the registry's derived profileMembership/
capabilityClusters so a capability's tier drives what installs + surfaces.
resolveProfile (when given the registry) unions capability skills for the
profiles its tier implies before the requires: closure; resolveSurface merges
capabilityClusters into the cluster map. bin/install.js, /gsd:surface, and the
capability-state resolver all thread the registry.

Shipped as a proven no-op: the UI capability is reconciled to tier:full (its
skills were full-only in the hand-authored profiles), so it contributes only to
the full profile (already the '*' sentinel) and core/standard are unchanged.
Equivalence tests prove resolveProfile/resolveSurface/listSurface/staging/
capability-state are identical with vs without the registry; the core-alias
staging path is verified equivalent (empty manifest → raw PROFILES.core).

Closes #949

1373f9bfb4 fix(#816): mirror install command-prefix handling in _syncGsdDir (#822)
* fix(#816): mirror install command-prefix handling in _syncGsdDir

applySurface() via _syncGsdDir handled command artifacts differently from a
fresh install. For flat command dirs (cursor/augment/opencode/kilo) install's
_copyStaged adds kind.prefix (gsd-<stem>.md) and _removeGsdEntries prunes
prefix-scoped, but _syncGsdDir copied staged files verbatim (unprefixed) and
pruned by exact name. So every /gsd:surface toggle wrote wrong filenames,
orphaned the installed gsd-*.md, and deleted user-authored command files.

_syncGsdDir's commands/agents branch now mirrors install:
- flat command dirs get the gsd- prefix on copy; namespaced dirs (commands/gsd)
  and agents keep staged names, using install's namespacedByDir rule
- prune is prefix-scoped so user files in shared flat dirs are preserved;
  namespaced commands/gsd stays membership-pruned so superseded commands are
  still removed on profile shrink

The naming rule is intentionally re-implemented (not via require('bin/install.js')
to avoid its module-load banner side-effect); a strict parity test asserts
applySurface and installRuntimeArtifacts produce identical command filenames for
opencode/kilo/cursor/augment/gemini, guarding against drift.

907cd01aa3 fix(#813): apply per-runtime skill path rewrites in applySurface (#817)
* fix(#813): apply per-runtime skill path rewrites in applySurface

applySurface() re-staged skill artifacts but, unlike installRuntimeArtifacts(),
never applied the per-runtime path rewrites. So /gsd:surface
(profile/enable/disable/reset) overwrote installed SKILL.md bodies with the
converter's default ~/.claude paths instead of the install target (pathPrefix),
silently regressing skill path references for every skillsKind runtime until
the next reinstall.

applySurface now mirrors installRuntimeArtifacts: for kind.kind === 'skills' it
derives pathPrefix the same way and applies applyRuntimeContentRewritesInPlace
on the staged dir before syncing.

- bin/install.js: export applyRuntimeContentRewritesInPlace
- runtime-artifact-layout.cts: carry resolved scope on Layout; export
  getInstallExports; type computePathPrefix/applyRuntimeContentRewritesInPlace
  on InstallExports
- surface.cts: lazily derive pathPrefix (only when a skills kind exists) and
  apply the rewrite via the shared getInstallExports accessor — single source of
  truth with install, only skills kinds rewritten (matches install)
- tests: regression test parameterized over cursor + codex asserting
  post-applySurface bodies carry the install pathPrefix, not ~/.claude
- CONTEXT.md: glossary updated for the applySurface rewrite parity + scope seam

Closes #813

* test(#813): normalize configDir prefix to forward slashes for Windows CI

The #813 regression assertion compared skill bodies against a raw
${configDir}/ prefix, but production derives pathPrefix via
path.resolve(configDir).replace(/\\/g, '/'). On Windows, mkdtempSync
returns backslash paths while the rewritten body uses forward slashes,
so the assertion would fail Windows-only (not covered by local gsd-test).
Normalize the expected prefix the same way production does.

df04aae5e4 enhancement(#537): migrate all hand-written bin/lib/*.cjs to TypeScript source of truth (ADR-457) (#602)
* enhancement(#537): migrate code-review-flags to TS source of truth

Collapse the hand-written get-shit-done/bin/lib/code-review-flags.cjs to a
TypeScript source of truth (src/code-review-flags.cts), compiled by tsc to a
gitignored .cjs build artifact at the same path, per ADR-457 (build-at-publish).
Second module after the semver-compare pilot (#541).

Behaviour is preserved byte-for-behaviour (characterization test added in
tests/code-review-flags.test.cjs locks the parser quirks). Adds compile-time
type checking: CodeReviewFlags interface + CodeReviewWorkflow literal union.
The require() path is unchanged, so code-review.md and the bug-3727 test keep
working. The emitted .cjs is gitignored and eslint-ignored, mirroring the pilot.

* enhancement(#537): migrate 9 leaf bin/lib modules to TS source of truth

ADR-457 build-at-publish, batch 1 (pure leaf modules, 0 sibling-deps):
001-legacy-orphan-files, context-utilization, redaction, artifacts,
command-arg-projection, clock, ui-safety-gate, review-reviewer-selection,
clusters. Each moves to src/*.cts (strict TS, typed), compiled by tsc to a
gitignored .cjs at the same require() path; behaviour preserved byte-for-

* chore(#537): add @types/node, drop hand-rolled node-globals shim

ADR-457 migration infra: replace the temporary src/node-globals.d.ts ambient
shim with @types/node@22 + "types":["node"] in tsconfig.build.json. Unblocks
migrating the ~49 remaining bin/lib modules that use node:fs/path/os/
child_process. Build + full suite (3030 pass) + lint all green; no .cts type
changes were needed (real Node types matched the shim).

* enhancement(#537): migrate 9 more bin/lib modules to TS (batch 2)

ADR-457 build-at-publish. Clean leaves: installer-migration-report,
prompt-budget. Type-error-prone leaves (were tsconfig.lint-excluded; now
strict-typed and removed from that exclude list): secrets, phase-lifecycle,
workstream-name-policy, decisions, validate, schema-detect. Plus
runtime-name-policy. Strict type fixes narrow unknown->concrete domain types

ADR-457. First cross-module TS->TS import: src/runtime-slash.cts imports
./runtime-name-policy.cjs and tsc resolves the sibling .cts types under strict
(no declaration files; NodeNext .cjs->.cts mapping), emitting a correct
require("./runtime-name-policy.cjs"). Confirms the recipe for coupled modules,
which must be migrated in dependency order (leaves-up). Suite green, lint clean.

plan-scan, fallow-runner, project-root, installer-migration-authoring,
update-context, 000-first-time-baseline, runtime-homes, model-catalog. Strict
typing fixed real issues (narrowing unknown, qualified fs/path calls, removed

projection keeps a namespace child_process import for mock-intercept
testability. loadConfig/migrateOnDisk emit synchronously (every caller uses
them sync; the one awaited migrateOnDisk caller tolerates a non-Promise) —

preserving all 63 exports via export=. All sibling deps already migrated
(shell-command-projection, model-profiles, model-catalog, worktree-safety,
planning-workspace, project-root, configuration, config-schema). Strict types,

#551 test hardcoded 12 now-migrated modules as "hand-written, must be linted";
that invariant is obsoleted by the ADR-457 migration. Rewrite it to a
filesystem-driven invariant that holds at every stage: a bin/lib/*.cjs must be
eslint-ignored IFF it has a src/*.cts source (tsc-generated), else linted
(covers package-identity, which has no TS source). Also eslint-ignore
config-types.cjs (has a src counterpart) and drop the redundant
tests/clock.test.cjs (clock already covered by clock-seam + bug-474 tests),
which tripped the lint-test-file-count ratchet.

ADR-457 build-at-publish: phases/verify/init/agent/task/validate/roadmap/state
command routers + workstream-inventory. Router handler results typed against
core's exported shapes; behaviour preserved (caught+fixed a --verify boolean

ADR-457 build-at-publish: gap-checker, docs, check-command-router, frontmatter,
learnings, gsd2-import, profile-pipeline. Behaviour preserved; full suite green
across all shards (only the 4 local gpg-env failures remain). Also broadens
atomic-write-coverage.test.cjs to accept the tsc-compiled namespace-import form
while still asserting platformWriteSync is called (safety guard intact).

* enhancement(#537): migrate config + profile-output to TS (batch 12)

ADR-457 build-at-publish: config (729 LOC), profile-output (1142 LOC). All
exports preserved; cmdMigrateConfig de-asynced (migrateOnDisk is sync, awaited
caller tolerates it). Behaviour preserved; suite green across all shards

ADR-457 build-at-publish: commands (1305 LOC), state (2074 LOC, 17 dependents).
All exports preserved; inner requires kept non-hoisted where load-order matters
(install.js, per-call security); acquireStateLock cast inlined to preserve the
err.code source token a structural test inspects. Behaviour preserved; suite

* enhancement(#537): migrate milestone to TS (batch 15a, hand-authored)

ADR-457 build-at-publish: milestone -> src/milestone.cts. Authored directly
(subagent capacity was unavailable). Also relaxes core.output()'s 3rd param to
optional, matching its real always-optional call contract (unblocks remaining
2-arg output callers). Behaviour preserved; suite green across all shards

* enhancement(#537): migrate phase, verify, init to TS (batch 15, final modules)

ADR-457 build-at-publish, Wave 7 (the last hubs): phase (1608 LOC), verify
(1615), init (2113). Adds src/package-identity.d.cts so verify can import the
permanently value-baked package-identity.cjs under strict TS.

Fixes two regressions the migration introduced in verify: restore
cmdValidateHealth's `return result` (callers/tests read result.warnings — it is
NOT side-effect-only), and make the bug-3384 source-pattern test tolerant of the
tsc-compiled bracket-notation form of the git_list_failed->W020 branch (behaviour
intact). Full suite green across all shards (only the 4 local gpg-env failures);
lint 0 errors. All 86 migratable bin/lib modules are now TypeScript sources.

* chore(#537): finalize ADR-457 migration — retire tsconfig.lint.json

All hand-written bin/lib/*.cjs are now src/*.cts sources, so the checkJs
stopgap tsconfig.lint.json (unused; not wired into eslint, scripts, or CI) is
deleted per ADR-457's final step. Also gitignore the tsc-generated
config-types.cjs (was still committed) for consistency with every other
emitted artifact. package-identity.cjs stays value-baked (declared via
src/package-identity.d.cts). Suite green; #551 ESLint-coverage test green.

* fix(#537): add prepare script so unpacked/git installs build bin/lib artifacts

ADR-457 build-at-publish: bin/lib/*.cjs are now gitignored, built by tsc. The
prepack/prepublishOnly hooks cover `npm pack`/publish, but `npm install -g
<dir>` and git installs run the `prepare` lifecycle — which was missing — so the
unpacked install shipped without the compiled .cjs and failed at startup with
"Cannot find module './lib/core.cjs'" (caught by the smoke-unpacked CI job).
Add `prepare` mirroring prepublishOnly (build:lib + build:hooks). prepare does
NOT run for registry consumers (they get the pre-built tarball), only for
source/local/pack installs.

Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

* fix(#537): make CI build/lockfile checks work with gitignored bin/lib artifacts

ADR-457 build-at-publish exposed two CI assumptions that bin/lib/*.cjs are
always present on disk:
- check:env's lockfile-sync ran `npm ci --dry-run`, which now triggers the
  `prepare` build (tsc) — but it runs before deps are installed, so tsc is
  absent and it misreported the lockfile as out of sync. Add --ignore-scripts
  (a lockfile check must not build).
- the lint-tests job installs with --ignore-scripts (no prepare build), but
  lint:skill-deps require()s the built install-profiles.cjs. Add an explicit
  `npm run build:lib` step after install.

Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

* fix(#537): narrow prepare to build:lib only (unbreak packed-smoke pack step)

prepare running build:hooks emitted "✓ Copying ..." stdout during `npm pack`,
which the install-smoke "Pack root tarball" step captures into $GITHUB_OUTPUT —
breaking it with "Invalid format". build:lib (tsc) is silent on success and is
all the unpacked/source install needs (the smoke-unpacked assertions exercise
gsd-tools, i.e. bin/lib, and tolerate hook setup with `|| true`). Matches
prepack. build:hooks still runs on prepublishOnly for real publishes.

* fix(#537): wire Stryker mutation gate to build-at-publish layout

The gate scored 0.00 because it mutated changed bin/lib/*.cjs that (a) were
generated artifacts and (b) included modules with no coverage in the command's
test set. Rework: mutation.yml now derives changed COVERED modules from
src/*.cts and maps them to their built bin/lib/*.cjs; Stryker mutates those
built artifacts with a no-rebuild command (mutating src/*.cts + per-mutant tsc
was ~3x over the 30-min CI budget).

NOTE: with the gate now correctly measuring the covered modules, their actual
mutation score is 42.94% (< break 50) — a pre-existing test-coverage gap
(adr-parser/prompt-budget/etc.), not introduced by this behaviour-preserving
migration. Reaching 50 needs more tests, a threshold/scope change, or a waiver —
a maintainer decision.

Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

* test(#537): raise mutation coverage of covered modules above the 50 gate

Adds focused example-based unit tests that kill surviving mutants in the two
lowest-scoring covered modules:
- tests/prompt-budget.unit.test.cjs (112 tests): 17.9% -> 97.9%
- tests/adr-parser.unit.test.cjs (205 tests): 44.7% -> 89.4%
Both wired into stryker.config.mjs's command. Fresh full run over the 6 covered
modules now scores 82.25% (>= break 50); every covered module is >= 68%.

Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

* enhancement(#537,#609): parallelize mutation gate via dynamic per-module matrix

The serial Stryker run timed out at 30 min once the migration's added tests
made every mutant re-run ~300 tests. Replace it with a dynamic matrix so the
gate completes well under budget — folded into this PR (was tracked as #609)
because it's a prerequisite for this PR's mutation gate to pass.

- scripts/mutation-matrix.cjs: single source of truth (covered-module -> test
  files) computing changed covered modules from git diff -> {has_work, matrix}.
- mutation.yml: detect -> dynamic `matrix: fromJSON(...)` mutate job (one
  parallel shard per changed module, scoped via MUTATION_TEST_CMD to only that
  module's tests, 15-min/shard) -> summary job that KEEPS the legacy check name
  "Stryker mutation score (changed files only)" so branch protection is
  unchanged. Per-shard jobs report as "Stryker (<module>)".
- stryker.config.mjs: commandRunner.command reads MUTATION_TEST_CMD (falls back
  to the full command locally).

Closes #609.

* test(#537,#609): give each mutation shard ≥50% on its own tests; drop blacksmith note

Per-module sharding revealed that active-workstream-store (46.5%) and
frontmatter (7.4%) only cleared 50% in the old serial run via timeout-noise from
the bloated 300-test command; on their own tests they were below the gate. Add
focused unit tests:
- tests/active-workstream-store.unit.test.cjs (115 tests): 46.5% -> 81.9%
- tests/frontmatter.unit.test.cjs (165 tests): 7.4% -> 63.4%
Both wired into scripts/mutation-matrix.cjs (per-module test map) and
stryker.config.mjs DEFAULT_TEST_CMD. All 6 covered modules now clear break:50
with only their own tests (config-schema/context-utilization/prompt-budget/
adr-parser already did). Also removes the leftover blacksmith TODO comment —
GitHub-hosted runners only; speed comes from parallel per-module shards.

* test(#537,#609): strengthen prompt-budget tests to clear the gate on its own tests

prompt-budget scored 39.58% when mutation-tested with ONLY its own tests (the
way the per-module CI shard runs it) — an earlier ~98% reading was inflated by
accidentally running the full multi-module command. Add 96 targeted tests to
tests/prompt-budget.unit.test.cjs (exact note-template text, plan-truncation
arithmetic/percentages, drop-block strings, noteInjected/hardFailed booleans):
scoped score 39.58% -> 68.75% (>= break 50). All 6 covered modules now clear
the gate on their own tests.
