The descriptor-driven gate must treat a runtime as layout-driven when its scoped
artifactLayout is non-empty (any kind), not only when it has a skills kind —
windsurf's global layout is agents-only and is a legitimate layout-driven runtime.
Preserve the three legacy special-cased paths (opencode/kilo combined path,
claude-local copyWithPathReplacement).
zcode falls into the default package.json+hooks path (not in the CommonJS-mode
exclusion roster), so its install contract is packageJson: true — matching
observed install output. No runtime === 'zcode' branch is added (AC#3): zcode
gets the default by not being excluded.
Resolve the zcode test cascade exposed by gsd-test:
- model-catalog.json: add zcode runtimeTierDefaults (null tiers, matching the
other profile-marker-only runtimes) so KNOWN_RUNTIMES stays parity with allRuntimes.
- runtime-name-policy: add zcode to GLOBAL_CONFIG_HOME_FRAGMENTS (~/.zcode) so
getGlobalConfigHomeFragment stops falling through to the .claude default.
- installer-migration-install: add the zcode fresh-install contract (flat-skills,
no settings, no package.json — same shape as trae).
- golden-install-parity: capture the zcode fixture via a standalone generator
script (not node --test — the gate stays gsd-test).
- capability-matrix.md: regenerate so zcode appears as a first-party row.
Fluidify the remaining count-pinned guards so adding a runtime no longer trips a
hand-pinned snapshot: gemini-runtime-removed (flag count derives from the
registry), non-claude-runtimes-registry-derivation (golden list derived from the
registry).
full_matrix fired on 15/15 sampled PRs because any tests/** change forced it,
costing ~25 runner-minutes each. A changed test file now always joins the
scoped windows lane (covering the #482 OS-specific failure class per-file)
and still runs on ubuntu 22/24 via targeted_tests; the residual macOS /
windows-node-22 cross-product is covered on every push to next.
Also narrows WINDOWS_HINTS from 6 substrings (102/633 files, a ~10-minute
scoped lane) to windows/win32/shell/path — the dropped hints (workflow,
install, hook) are either platform-independent lint tests or already covered
by fullMatrix rules.
