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-
behaviour. Adds src/node-globals.d.ts (minimal ambient shim; "types":[]).

* 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
(no any/ts-ignore); behaviour preserved. Full suite green, lint 0 errors.

* enhancement(#537): migrate runtime-slash to TS (cross-import proof)

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.

* enhancement(#537): migrate 10 more bin/lib modules to TS (batch 3)

ADR-457 build-at-publish, Wave-1 leaves: event, workstream-inventory-builder,
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
unnecessary casts); plan-scan/project-root/workstream-inventory-builder dropped
from tsconfig.lint exclude. Behaviour preserved; suite green, lint 0 errors.

* enhancement(#537): migrate 5 large Wave-1 leaves to TS (batch 4)

ADR-457 build-at-publish: configuration, state-document, shell-command-
projection (42 dependents), security, command-aliases. shell-command-
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) —
full suite (3030 pass) confirms behaviour preserved. configuration/
state-document/command-aliases dropped from tsconfig.lint exclude. Also fixes
the malformed batch-3 changeset frontmatter (type/pr) that failed lint:docs.

* enhancement(#537): migrate 6 Wave-2 modules to TS (batch 5)

ADR-457 build-at-publish: config-schema, model-profiles,
002-codex-legacy-hooks-json, logger, active-workstream-store, adr-parser.
First batch importing already-migrated siblings (configuration, model-catalog,
shell-command-projection, redaction, security) via ./sibling.cjs specifiers.
Strict type narrowing (typeof guards over String(unknown)); behaviour
preserved; suite 3030 pass, lint 0 errors.

* enhancement(#537): migrate 5 large Wave-2 modules to TS (batch 6)

ADR-457 build-at-publish: graphify, install-profiles, intel,
installer-migrations, worktree-safety. installer-migrations preserves its
dynamic require() loader for numbered migration modules (scoped lint
suppressions). Strict typing (typeof guards over String(unknown)); behaviour
preserved; suite 3030 pass, lint 0 errors. Wave 2 complete.

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

* enhancement(#537): migrate Wave-3 modules to TS (batch 7)

ADR-457 build-at-publish: planning-workspace, runtime-artifact-layout,
command-routing-hub, drift. Uses `import x = require()` for export= siblings;
drift's lazy require of runtime-slash hoisted to a top-level import (verified
non-circular). Behaviour preserved; suite 3030 pass, lint 0 errors.

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

* enhancement(#537): migrate small Wave-4 modules to TS (batch 8)

ADR-457 build-at-publish: cjs-command-router-adapter, phase-command-router,
surface, roadmap-upgrade. Typed the hub router handler results as the HubResult
discriminated union; surface drops 4 genuinely-unused imports. Behaviour
preserved; suite 3030 pass, lint 0 errors.

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

* enhancement(#537): migrate core hub (2.5k LOC, 68 dependents) to TS (batch 9)

ADR-457 build-at-publish: get-shit-done/bin/lib/core.cjs -> src/core.cts,
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,
no any/ts-ignore; config-schema lazy require hoisted (non-circular). Behaviour
preserved (independently verified: core's shard 3030 pass / 0 fail).

* test(#537): make ESLint-coverage + test-sprawl checks migration-aware

#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.

* enhancement(#537): migrate 9 Wave-5 router/inventory modules to TS (batch 10)

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
flag regression mid-migration). Full suite green across all shards (only the 4
local gpg-env changeset-notes failures remain; CI passes them).

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

* enhancement(#537): migrate 7 Wave-5 modules to TS (batch 11)

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).

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

* 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
(only the 4 local gpg-env failures). Wave 5 complete.

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

* enhancement(#537): migrate 5 Wave-6 modules to TS (batch 13)

ADR-457 build-at-publish: template, uat, workstream, roadmap, audit. Behaviour
preserved (dead toPosixPath import dropped from audit; inline requires hoisted).
Suite green across all shards (only the 4 local gpg-env failures).

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

* enhancement(#537): migrate commands + state hubs to TS (batch 14)

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
green across all shards (only the 4 local gpg-env failures). Wave 6 complete.

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

* 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
(only the 4 local gpg-env failures).

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

* 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.

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

* 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.

/**
* Prune GSD-managed skill directories from a skills directory.
*
* Removes every directory in `skillsDir` that is GSD-owned but NOT listed
* in `retainedNames`. User-owned dirs (not matching the GSD ownership criteria)
* are always preserved.
*
* Ownership criteria:
* - Non-empty prefix (e.g. 'gsd-'): dir name starts with that prefix AND
* appears in the manifest (manifest membership is required). Dirs that match
* the prefix but are NOT in the manifest are treated as user-owned and
* preserved — this prevents data loss for user-created gsd-* directories.
* A warning is written to stderr when such a dir is encountered.
* - Empty prefix (Hermes): dir name appears as a canonical skill stem in the
* manifest. User dirs not in the manifest are preserved.
* - Empty prefix without manifest, or manifest not a Map: conservative; no
* dirs are removed.
*
* This is the single point of truth for skill-dir pruning. Both _syncGsdDir
* (surface apply) and callers that need stand-alone pruning use this function.
*
* @param skillsDir directory that contains the gsd-STEM sub-dirs
* @param retainedNames set of directory names to keep (e.g. 'gsd-help')
* @param prefix GSD dir prefix, e.g. 'gsd-' (or '' for Hermes)
* @param manifest optional; required for Hermes empty-prefix case
* and for manifest-membership gate in prefixed case.
* Must be a Map; any other type is treated as missing.
