- Coverage gate (test:coverage:unit) now runs inside the ubuntu/24 full lane; the standalone coverage job duplicated that lane's entire unit run (~4 min of runner time per PR). required-tests gate updated accordingly. - New second-tier floor: c8 check-coverage --lines 55 over scripts/** re-slices the same V8 data (measured 65.95%) — the CI/release/lint tooling was previously enforced at 0%. - Coverage artifact now excludes coverage/tmp (>1 GB of raw V8 dumps). - lint-tests runs npm run lint:ci — one orchestrated step, identical set locally and in CI; drops the no-op eslint --cache flag (CI never restored the cache directory). - Delete unreferenced scripts/run-cross-platform-tests.cjs (+ its test); document the mutation UNMUTATED blind spot (~48% of lib lines) in stryker.config.mjs.

/**

* stryker.config.mjs
|
|
*
|
|
* Mutation testing configuration for gsd-core.
|
|
*
|
|
* Test runner: 'command' (built into @stryker-mutator/core)
|
|
* Runs: node --test over the lib test files via the repo's run-tests invocation.
|
|
*
|
|
* Mutate scope: bin/lib/**\/*.cjs, excluding generated files and test files.
|
|
*
|
|
* coverageAnalysis: 'off' — command runner does not support per-mutant coverage
|
|
* thresholds: high=80, low=60, break=50
|
|
* incremental: true — caches results; PR-scoped runs pass --mutate <changed-files>
|
|
*
|
|
* Reports:
|
|
* - html: reports/mutation/mutation.html
|
|
* - clear-text (console)
|
|
* - progress (spinner)
|
|
*
|
|
* NOTE: This is incremental / changed-files-only in CI (--mutate <changed-files>)
|
|
* to stay bounded. Full runs are for local exploration only.

// ADR-457: bin/lib/*.cjs are gitignored build artifacts (compiled from
|
|
// src/*.cts by `npm run build:lib`, which the mutation CI job runs via `npm ci`
|
|
// → prepare before Stryker). Stryker mutates the *built* .cjs directly — the
|
|
// command runner runs the tests with NO rebuild, so each mutation to the
|
|
// shipped artifact is seen by the tests. (Mutating src/*.cts instead would
|
|
// force a full tsc rebuild per mutant — far too slow for the 30-min CI budget.)
|
|
// Large/low-coverage modules are excluded (the command's test set does not
|
|
// exercise them, so they would only ever produce survived mutants).
|
|
//
|
|
// KNOWN BLIND SPOT (2026-06 CI audit): this list excludes ~14.2k of ~29.8k
|
|
// lib lines (~48%), including the most central modules (state, core,
|
|
// commands, phase, verify). Mutation results therefore speak only for the
|
|
// well-tested half of the lib. Shrinking the list is deliberate tracked work:
|
|
// bring one module into scope per release by first giving it per-module
|
|
// *.unit.test.cjs / *.property.test.cjs coverage, then deleting its entry —
|
|
// never delete an entry without that coverage (it will only produce survived
|
|
// mutants and trip the break threshold).
