Previously a capability that failed to LOAD (e.g. incompatible engines.gsd) but
declared a gate-kind loop hook caused the loop resolver to inject a BLOCKING
synthetic gate (blocking:true, onError:halt) at every declared point, halting
every ship:pre / verify:post project-wide over an unrelated load error, with no
remediation surfaced.
Per maintainer decision (#2009) it now fails OPEN: no gate is injected (the loop
proceeds; --active-cap correctly reports the failed cap inactive) and a loud
warning is emitted — to stderr (the channel host workflows/agents actually see)
and in the envelope 'warnings' array — naming the load reason and the exact
'gsd capability remove <id>' remediation. The loader still records blockedGates;
only the consequence changes from block to warn.
Security (review): capId and reason originate from a third-party manifest /
directory name. capId is validated against the canonical kebab-case id shape
before it is placed in the runnable remediation command (withheld otherwise);
reason is stripped of control chars and backticks. This closes an argument/
prompt-injection vector in the surfaced message.
Docs updated to the fail-open-warning posture (ARCHITECTURE, INVENTORY,
CONFIGURATION, README, capability-overlay-model). Also removes a dead 'before'
import surfaced by lint in the issue-2045 test.
The flattened install layout broke the third-party capability ecosystem in two
ways. Both are fixed at the host-version / installer boundary.
Gap 1 — host version read as 0.0.0. The running GSD version was resolved via
require('../../../package.json') (loader/source) and require('../../package.json')
(the gsd-tools CLI), which in the installed layout is the versionless CommonJS
marker → the fail-closed fallback reported 0.0.0, so `capability install` rejected
any manifest with a real engines.gsd range as "incompatible with GSD 0.0.0". For
runtimes that get no marker, and for local installs, that walked-up package.json
could even be the USER's own project, reporting a wrong version. Fix:
readHostVersion() (capability-loader.cts, capability-source.cts) and capHostVersion()
(gsd-tools.cjs) now prefer the authoritative gsd-core/VERSION the installer already
writes for EVERY runtime (mirrors resolveVersionFrom(), #1383), falling back to the
runtime-root package.json for the dev/source tree, then fail-closing. This fixes
every runtime and the actual `capability install` CLI path without touching the
marker package.json, so uninstall is unchanged (no data-loss surface).
Gap 2 — scripts/gen-capability-registry.cjs (+ its sibling
gen-loop-host-contract.cjs) were never copied by the installer, so the loader's
never-crash invariant discarded every overlay and fell back to the frozen
first-party registry (installed capabilities silently inert). Now copied,
uninstalled, and manifest-tracked exactly like fix-slash-commands.cjs (#1223).
Regenerates the 16 golden-install-parity fixtures to capture the two newly shipped
generator scripts and the gsd-tools.cjs change.
Regression tests (RED→GREEN): readHostVersion VERSION-first / fallback / fail-closed
resolution; an end-to-end `capability install` against a REAL installed layout
proving the engines gate sees the real host version, not 0.0.0; and a real-install
check that both generators are shipped and manifest-tracked.

* feat(#1435): capability matrix (generated + drift-guarded) + trust-model doc consolidation
ADR-1244 Phase 6. Adds the capability matrix reference, generated FROM the committed registry so it
can never drift from the actual capability set:
- scripts/gen-capability-matrix.cjs (--write / --check); --check is a CI drift guard.
- tests/capability-matrix-sync.test.cjs (4 tests): drift guard, buildMatrix==committed, every cap
present, no placeholders.
- docs/reference/capability-matrix.md regenerated from the registry (release-stable: shows engines.gsd,
omits the lockstep per-cap version that would churn the file every release).
- Consolidated the duplicate trust-model doc: deleted docs/explanation/the-capability-trust-model.md,
merged its content into capability-trust-model.md, redirected ~10 references; no stale links remain.
- Diataxis verification (now that gsd capability is a real command): corrected the matrix's third-party
section — the matrix is the first-party catalogue; the overlay-aware view of installed third-party
capabilities is 'gsd capability list', not this generated file.

Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
* fix(#1435): address code-review — non-vacuous matrix test + generator polish
- capability-matrix-sync.test.cjs: assert the 'security registers a ship:pre gate' precondition
unconditionally so the extension-point check can never degrade to a vacuous pass on registry drift.
- gen-capability-matrix.cjs: warn (stderr) on an unknown loop point at generation time; rename
enginesOf -> fmtEngines for consistency with the other fmt* helpers (output unchanged).
- capability-trust-model.md: point the two how-to links at the real files
(import-a-capability-from-a-url.md, version-a-capability.md) instead of the bare directory.

ADR-1244 Phase 5 (D7). dispatchOverlayCapabilityCommand in gsd-tools.cjs dispatches an installed third-party capability command family via loadRegistry({includeInstalled}), gated on a committed ledger entry (consent) and confined to the capability's install root (defaultRequireFromInstallRoot: bare-.cjs basename + realpath containment, rejects ../ traversal + symlink escape); same own-property/function/sync/ExitError guards as the first-party path. capability-loader records _overlay.commandRoots only for accepted overlay caps with a committed, structurally-valid ledger entry (fail closed). First-party graphify/intel/audit unchanged (already on the registry seam). 3 Codex rounds converged + /security-review (no HIGH) + /code-review (Approve); gsd-test green both platforms; CI green.
Closes#1434.

* feat(#1431): runtime capability registry overlay (ADR-1244 Phase 2)
Promote the registry from a frozen data file to loadRegistry({includeInstalled}),
composing the first-party registry with a validated installed overlay (ADR-1244 D2):
- Extract the conformance validator to a shared runtime-callable module
(gsd-core/bin/lib/capability-validator.cjs); the generator re-exports it
verbatim, guarded by a generative-parity test (no build-time/runtime drift).
- capability-loader.cts: loadRegistry({includeInstalled}) composes first-party
∪ validated overlay from $GSD_HOME/.gsd/capabilities (global) and
<root>/.gsd/capabilities (project) via the canonical buildRegistry. First-party
always wins (id/skill/agent/config/command-family + reserved gsd-/anthropic-
prefixes); full merged-set cross-capability validation; engines.gsd load-time
re-gate (skip-with-warning); gate-kind capabilities FAIL CLOSED; fragment-path
escapes rejected.
- semverSatisfies (hand-written, no dep) for the engines.gsd gate, fail-closed.
- Wire surface/state + loop to the overlay; loop injects a blocking gate for each
skipped gate-kind overlay (fail-closed).
- cwd-aware overlay config-key federation: config-loader _federatedConfigSchema(cwd)
+ config-schema isValidConfigKey(key, cwd) compose the overlay per loadConfig/
config-set call (never eager at module load, never wrong-cwd); first-party path
unchanged with no cwd.
- run-tests.cjs sandboxes GSD_HOME (idempotent — nested spawns reuse it) for test
hermeticity; capability-loader.cjs git+eslint-ignored (tsc artifact);
capability-validator.cjs stays linted (#551 migration coverage).
Closes#1431

* test(#1431): kill config-schema cwd-aware federation mutants (Stryker ≥52)
The cwd-aware overlay config-key federation added to config-schema.cts
(_capabilityConfigSchema(cwd) + isCapabilityConfigKey/isValidConfigKey cwd
threading) introduced mutable surface uncovered by config-schema's mutation
test set, dropping its score to 39.58% (below the 52 break threshold). Add a
real-overlay-fixture describe block exercising every branch (cwd guard, overlay
loadRegistry, found-branch, first-party fallback, cwd threading); local Stryker
score 39.58% -> 77.08%.
