Michał Pierzchała	60400d04b7	feat(mutation): add target-annotation-serde + snapshot-occlusion kernels (#1553) ... * feat(mutation): add target-annotation-serde + snapshot-occlusion kernels Both are pure decision kernels the lane's own membership rule covers (target-annotation-serde: parse/validate/normalize the .ad comment-line codec, zero I/O; snapshot-occlusion: pure covered/not-covered decision where a wrong answer silently blocks or mis-allows a tap) but were excluded from KERNEL_MODULES. Fixing the harness's packages/*/src blind spot was required, not optional: test-scope.ts, ownership.ts, and vitest.mutation.config.ts all hardcoded `src/` as the only place a kernel's tests could live. target-annotation-serde's own tests live under packages/ad-script/src/internal/__tests__/, so without this fix the module would score 0% from day one — not from weak tests, but because its test file was silently invisible to the lane. Widened the same three places, plus mutation-affected.yml's path filter and isTestFile/ownedTestFiles in ownership.ts, to also recognize packages/*/src/**/*.test.ts (mirroring vitest.config.ts's own unit-core project include list). Triaged every surviving mutant from the initial run: real coverage gaps got a new/adjusted test (kill-with-test), everything else is documented equivalent with an inline comment at the mutation site explaining the invariant that makes it unobservable (redundant early-returns, JSON.stringify dropping undefined-valued keys, Number.isFinite/isSafeInteger's total-function safety, caller-enforced positiveRect/candidate invariants, etc). Baseline recorded from the actual measured run, not inherited or guessed: 94.03% (315/335) and 89.74% (175/195). * style: run the formatter over the four files the gate flagged	2026-08-02 11:36:43 +02:00
Michał Pierzchała	76453add71	refactor: pnpm workspace + @agent-device/kernel pilot (#1490 W0) (#1494) ... * refactor: pnpm workspace + @agent-device/kernel pilot (#1490 W0) Extend the workspace with packages/* and move the kernel behind an enforced public API: packages/kernel with nine consumer-earned subpath exports (errors, device, snapshot, contracts, collections, rect, redaction, daemon-error, bounds — the last absorbed from utils as Rect vocabulary). Every kernel import repo-wide becomes the @agent-device/kernel/<sub> specifier; kernel tests move to src/__tests__/kernel/ and exercise the package surface. The root declares the package in devDependencies (workspace:*), tsdown bundles it (noExternal) so the published artifact and its runtime dependency manifest are unchanged. Gate rewiring in the same change, per the W0 brief: - R1 kernel-sink retires (physically subsumed); new R11 package-boundaries guards no-root-back-imports, relative tunnelling past exports maps, undeclared workspace deps, and non-exported subpaths, with runtime resolution pins via import.meta.resolve. - resolveImportEdges and mutation ownership follow workspace specifiers through exports maps, keeping R4 cycle checks, depgraph, and derived test ownership connected across the seam (kernel-errors still owns 495 tests). listSourceFiles includes packages/*/src. - kernel becomes an unranked zone; mutation registry, stryker mutate globs, and the mutation-affected workflow path filter move to packages/kernel/src/errors.ts. - check:affected gains packages/ ownership (manifests fail open); vitest and coverage include packages/*/src; fallow ignores packages/** (its resolver cannot follow workspace specifiers). - The affected-selector CI job installs dependencies: its closure now crosses workspace specifiers, and the R8 relative exception is unsafe for production src files (Node ESM does not realpath, so dual specifier/relative loads would instantiate modules twice). The R8 zero-dep set is pinned empty with that rationale. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01FUv7bvbWNryuXgSBuqTtep * fix: address W0 review — mutation sandbox, exports-map resolution, tsc -b Review findings on #1494, all five: 1. contracts-schema-public.test.ts reads the kernel source at its packages/ path (fs access invisible to the codemod and typecheck). 2. Mutation lane: Stryker sandboxes the tree but pnpm's node_modules symlink resolves @agent-device/* back to the real repo, so mutants in the sandbox never load and vitest.related finds no tests. vitest.mutation.config.ts now aliases each EXPORTED specifier to its source (derived from exports maps, never a wildcard), keeping resolution inside the mutated tree. Validated: kernel-errors module runs end to end (dry run 3,984 tests, mutants killed, exit 0). 3. Layering/depgraph resolve workspace specifiers through the exports-derived map (workspaceSpecifierTargets) instead of reconstructing paths, so '.'-facade packages resolve; the positional fallback remains only for map-less fixtures (P0 pin). 4. Per-package project references implemented: packages/kernel is composite (emitDeclarationOnly -> dist-types, gitignored), the root references it, and typecheck becomes tsc -b — probed to catch type errors on both sides under TypeScript 7 native. 5. R11's relative-route exception now requires membership in an actual R8 zero-dep job closure (zeroDepClosureFiles walks entries), not mere scripts/ placement — closing the dual-instantiation bypass. Also from review discussion: daemon-error moves out of the kernel package to src/client/ — its consumers (cli, client facade) rehydrate wire DaemonErrors client-side; the daemon only produces them. Kernel drops to 8 exported subpaths before any of them ship. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01FUv7bvbWNryuXgSBuqTtep * refactor: one exports-map reader for mutation alias and ownership Fallow flagged workspaceExportAliases (cognitive 15, CRAP 90). The manifest-reading logic already exists as workspaceSpecifierTargets in scripts/layering/package-boundaries.ts, so both the Stryker sandbox alias table and the mutation ownership walker now consume it instead of carrying near-clones. Behavior unchanged; mutation suite 45/45 and changed-code fallow green. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01FUv7bvbWNryuXgSBuqTtep * fix: composite kernel without a root references edge FreeRange runs plain `tsc -p tsconfig.json`, and a root `references` entry makes non-build-mode TypeScript demand the referenced project's built declarations (TS6305) — a standing "build first" tax on every plain -p consumer (fr, editors). Keep the per-package composite project and build it in typecheck (`tsc -b packages/kernel` before the root and examples/sdk passes), but drop the root references edge: root consumption resolves through exports to source, identical to runtime and to the bundler. Probed: plain -p green with no prebuilt output; kernel-side type errors still caught by its own build. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01FUv7bvbWNryuXgSBuqTtep * fix: R11 uses the layering parser; mutation config is a fallow entry Review blockers on #1494: - R11's private single-quote regex could miss a double-quoted or re-export route into packages/*/src. specifierSites now delegates to the layering model's parseImports (both quote styles, side-effect imports, re-exports, dynamic imports), with direct regressions for each formerly-invisible form. - vitest.mutation.config.ts becomes a declared fallow entry instead of a tolerated unused-file finding: the full-repo audit now reports it reachable (unused files 2 -> 1; the remainder predates this PR). FreeRange clean-checkout evidence: with packages/kernel/dist-types and every *.tsbuildinfo deleted, `pnpm check:freerange` reports 0 findings on this head — the TS6305 topology died with the root references edge in the previous commit; check:freerange has no build precondition.

Michał Pierzchała	d6d2e09529	test(kernel): cover all six errors.ts exports, kernel-errors mutation 55.19% → 86.26% (#1475) ... * test(kernel): cover all six errors.ts exports with table-driven cases (#1456) Extends errors.test.ts beyond normalizeError/toAppErrorCode: - AppError construction and NormalizedError/AppError instanceof contract - asAppError identity/wrap/duck-typing behavior (cross-realm errors, non-Error throws, fallback code precedence) - isAgentDeviceError real-instance-only contract - retriableForErrorCode and defaultHintForCode, table-driven over KNOWN_APP_ERROR_CODES (the module's own source of truth) rather than a hand-copied code subset - normalizeAgentDeviceError delegation to normalizeError - a cross-cutting composition test asserting the retriable/hint contract request-router.ts's enrichDaemonError and the CLI's printHumanError actually rely on No production changes; mutation re-run and PR to follow. * test(kernel): pin maybeEnrichCommandFailedMessage gating and regex boundaries (#1456) Adds targeted cases for branches the table-driven/contract tests didn't reach: the COMMAND_FAILED/processExitError/string-stderr gating in maybeEnrichCommandFailedMessage, GENERIC_EXIT_MESSAGE's `-?\d+$` boundary (negative code, trailing text, non-numeric code, whitespace in the tool token), and STDERR_NOISE_PREFIX's zero-or-more-whitespace semantics for both the adb/xcrun/simctl and "error:" groups. * test(kernel): close remaining mutation gaps in firstStderrLine/detail helpers (#1456) Each addition here was verified against a hand-applied mutation (matching Stryker's actual survivor diffs) before landing, confirming it fails on the mutant and passes on the original: - firstStderrLine: line-trim-before-prefix-match (a real skip-pattern line ahead of the leading-whitespace one is required, since redactDiagnosticData already .trim()s the whole stderr string once before firstStderrLine ever sees it), and the >200-char truncation branch (both sides of the boundary: 200 exact vs 201+). - stringDetail/booleanDetail: reject a wrong-typed diagnosticId/logPath/ hint/retriable instead of surfacing it. - stripDiagnosticMeta: details drops to undefined once stripping the known meta keys leaves nothing behind. * style(kernel): apply oxfmt to errors.test.ts Fixes the Lint & Format CI failure on PR #1456 — format:check flagged this file, oxfmt --write resolves it with no behavior change. * test(kernel): split errors.test.ts into focused sibling suites (#1456) Per review feedback: the growing errors.test.ts hit 601 lines, past AGENTS.md's extract-before-500 threshold (tests are not exempt). Splits along the reviewer's requested seams, moving tests verbatim with no assertion changes: - errors-message.test.ts (234 lines) — stderr/message normalization: maybeEnrichCommandFailedMessage, firstStderrLine, the GENERIC_EXIT_MESSAGE/STDERR_NOISE_PREFIX regex boundaries. - errors-metadata.test.ts (157 lines) — hint/diagnosticId/logPath/ retriable/supportedOn lifting and stripping, divergence passthrough, the stringDetail/booleanDetail/stripDiagnosticMeta type-guard contracts, and the normalizeError/retriableForErrorCode/ defaultHintForCode cross-cutting contract. - errors-code-policy.test.ts (228 lines) — AppError construction, asAppError/isAgentDeviceError duck-typing contract, toAppErrorCode, the retriableForErrorCode/defaultHintForCode table-driven policy tests, and normalizeAgentDeviceError. Also repoints scripts/mutation/ownership.test.ts's two references to the deleted errors.test.ts path at errors-code-policy.test.ts — the mutation ownership deriver reads the file from disk to follow its import graph, so a stale path silently resolves to "owns nothing" instead of failing loudly. --------- Co-authored-by: Claude <noreply@anthropic.com>	2026-07-28 20:06:03 +02:00

devin-ai-integration[bot]	8cce0ef6b8	test: ratchet mutation score over enumerated decision kernels (#1441) ... * test: ratchet mutation score over enumerated decision kernels Adds a Stryker (vitest runner) mutation lane scoped to the decision kernels, a per-module baseline with tool/config provenance, and a ratchet that only lets scores rise. Non-gating until two consecutive stable weekly sweeps. Refs #1415 Co-Authored-By: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com> * chore: declare the mutation test-scope seam for production-export analysis Co-Authored-By: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com> * test: own kernel tests in the mutation registry and ship the #1430 lane envelope - restore bench:help-conformance, broken by a formatting-path edit - kernel test files select their module on PRs (registry `tests` + workflow paths), asserted to reach the kernel through the import graph - every mutation run writes the standard scheduled-lane artifact envelope - move src/utils/__tests__/errors.test.ts beside its source per the mirror rule Refs #1415, #1430 Co-Authored-By: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com> * test: derive kernel test ownership and land the scheduled-lane health monitor Ownership of a kernel's tests is now computed from the static import graph (scripts/mutation/ownership.ts) instead of a hand-listed set, so a test that reaches a kernel indirectly -- src/__tests__/daemon-error.test.ts through src/daemon.ts -- selects that kernel on a PR. The PR lane triggers on every src test and shards the derived modules, keeping wall clock at one module. The lane envelope (#1430) is now written on every exit path with the stage it reached, so a crash before any mutant runs is distinguishable from a lane that never ran. Adds the derived cadence monitor (scripts/lane-health, daily workflow): scheduled lanes are enumerated from .github/workflows/ and reported dark, failing, or never-run against their own cron cadence. * fix: merge only Stryker reports from a shard directory The shard artifacts now carry the lane envelope beside mutation.json, and the merge globbed every .json under the download path, so the ratchet job fed the envelope to the report parser and died after the mutants had already run. * fix(mutation): fail on incomplete shard sets and envelope pre-run failures Co-Authored-By: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com> * fix(mutation): downgrade a passing envelope when a later lane step fails Co-Authored-By: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com> * refactor(mutation): shard by registry, defer the PR lane, drop the bundled watcher Co-Authored-By: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com> * docs: describe registry sharding and the deferred PR mutation lane Co-Authored-By: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com> * fix(mutation): make the pre-graduation tooling exception select real mutants Co-Authored-By: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com> * test(mutation): give the worktree fixture commits their own identity Co-Authored-By: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com> --------- Co-authored-by: Michał Pierzchała <thymikee@gmail.com> Co-authored-by: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com>	2026-07-28 10:07:14 +02:00
