Tom Boucher 463cffd894 chore(#604): rename get-shit-done/ runtime directory to gsd-core/ (#615)
* chore(#604): rename get-shit-done/ runtime directory to gsd-core/

Renames the installed runtime directory `get-shit-done/` to `gsd-core/` so the
on-disk name matches the package (`@opengsd/gsd-core`), repo, and binary
(`gsd-tools`). The npm package name and binary are unchanged; npx/npm consumers
are unaffected.

Mechanical (bulk, ~90% of the diff):
- `git mv get-shit-done gsd-core`
- Swept path/identifier references across the repo via
  `perl -pe 's/get-shit-done(?!-\w)/gsd-core/g'`. The negative lookahead
  preserves the five legitimate slug variants that are NOT the directory:
  get-shit-done-{OLD,cc,classic,cli,redux} (old package/repo names).
- Build/manifest wiring: package.json (bin, files, coverage globs),
  tsconfig.build.json (outDir), ~86 .gitignore build-output entries,
  stryker.config.mjs, scan-ignore files, install.js path strings.
- Frozen (not rewritten): CHANGELOG.md history; translated docs
  (README.<locale>.md and docs/{ja-JP,ko-KR,pt-BR,zh-CN}/).

New logic (review here):
- src/installer-migrations/003-rename-get-shit-done-to-gsd-core.cts: a proper
  ADR-0008 installer migration. On upgrade it walks the legacy
  `~/.claude/get-shit-done/` tree, classifies each file via the prior install
  manifest, and emits remove-managed / backup-and-remove for managed files
  while PRESERVING unknown user-added files. Symlink-safe (skips a symlinked
  root and symlinked entries; bounds-checks every path under configDir). The
  framework rolls back on install failure. Emptied dirs may remain (framework
  has no recursive dir-removal primitive) — documented.
- scripts/lint-legacy-dir-name.cjs: CI regression guard forbidding the bare
  `get-shit-done` directory token (split token to avoid self-match; case-
  insensitive; `(?!-\w)` lookahead allows the slug variants; allowlists
  CHANGELOG, translated docs, and `gsd-allow-legacy-name` marker lines).
  Wired into the lint-tests CI job.
- Restored scripts/lint-package-identity-drift.cjs detection regexes (the
  mechanical sweep had wrongly rewritten the old-name patterns it exists to
  detect) and marked them as intentional legacy references.
- TDD tests for the migration and the guard; do.md slash-command guard regex
  tightened so a `/gsd-core/bin` path segment is not mistaken for a command;
  changeset + docs/installer-migrations.md row added.

Breaking: the installed runtime path moves `~/.claude/get-shit-done/` ->
`~/.claude/gsd-core/`. Migration 003 removes the stale legacy dir's managed
files (preserving user files) on upgrade. Users with custom hooks/configs
hardcoding the old path must update them.

Closes #604

* fix(#604): unsweep pending changesets + allowlist injection-example docs

CI fixes for the rename PR:
- Do not sweep pending .changeset/*.md (ephemeral release-note fragments,
  like CHANGELOG); reverted those body edits so 5 pre-existing malformed
  fragments (missing type/pr) no longer enter the PR diff and trip docs-lint.
  Allowlisted .changeset/ in the legacy-name guard accordingly.
- Allowlisted TEST-EXAMPLES.md and docs/explanation/security-model.md in
  prompt-injection-scan.sh: they contain intentional injection examples /
  security-model prose; the path-reference rewrites are kept.

CodeQL alerts on this PR are pre-existing (alert lines unchanged by this PR;
none in the new migration/guard) and are out of scope for the rename.

* fix(#604): resolve CodeQL alerts surfaced on this PR

The rename diff touched files carrying pre-existing CodeQL findings; per the
no-pre-existing-dismissal rule, fixing every surfaced alert rather than waving
them off. All behavior-preserving:

- scripts/ci-test-scope.cjs: build the config-path match from string
  .includes() instead of a RegExp over an arg-derived value (js/regex-injection).
- src/profile-output.cts: escape backslashes before pipe-escaping desc/safeName
  so the table-cell escape is complete (js/incomplete-sanitization).
- tests/{bug-2643,bug-2808,docs-parity-live-registry}: two-pass HTML-comment
  strip so a bare/unclosed `<!--` cannot survive (js/incomplete-multi-character-sanitization).
- tests/inline-plan-threshold: drop the no-op `\s`->`\s` identity replace,
  keep the meaningful POSIX-class conversion (js/identity-replacement).

Verified: build:lib green; the touched test files + ci-test-scope + profile-output
suites pass; lint:legacy-name clean.

* fix(#604): correctly resolve remaining CodeQL alerts (regex-injection + sanitization)

The prior commit's fixes for two alerts were ineffective:
- ci-test-scope.cjs js/regex-injection: the alert is the CLI-arg-derived `file`
  reaching static regex `.test(file)` calls (not the config rule). Removed ALL
  regex over file/t — startsWith/includes/=== string checks + an isWindowsHint
  helper — so there is no regex sink for the tainted value.
- js/incomplete-multi-character-sanitization (3 test files): a single
  `.replace(/<!--...-->/g,'')` can let `<!--` re-form. Replaced with a fixpoint
  loop (replace until stable) plus a final bare-opener strip.

Verified: no regex over file/t remains; ci-test-scope + the 3 test suites pass;
lint:legacy-name clean.

* fix(#604): make ci-test-scope + comment-strippers regex-free to clear CodeQL

CodeQL flags the regex PATTERNS syntactically (regex-injection on the
--files arg split; incomplete-multi-character-sanitization on the <!--...-->
replace), so loop fixes do not satisfy it. Made these paths regex-free:
- ci-test-scope.cjs splitFiles: char-by-char separator tokenizer (no /[,\\s]+/).
- 3 test files: indexOf/slice HTML-comment stripper (no .replace(/<!--/)).
Behavior preserved; ci-test-scope + the 3 suites pass; guard clean.

* fix(#604): unblock security base64 scan on the large rename diff

The security job hit its 10m timeout: base64-scan.sh choked on the binary
test fixture tests/feat-3594-parser-property-style.test.cjs (embedded NUL/
non-UTF8 bytes -> thousands of bogus blobs + "ignored null byte" warnings),
and the ~800-file rename diff is slow to scan regardless.

- scripts/base64-scan.sh: skip binary-by-content files (grep -Iq .) — they
  can't carry base64-obfuscated *text* and feeding NUL bytes through the
  per-line scanner is pathologically slow. collect_files already filtered
  binary *extensions*; this catches binary *content* in text extensions.
- .github/workflows/security-scan.yml: raise the security job timeout 10m->30m
  to accommodate very large diffs (the scan itself is unchanged).

Verified locally: scan skips the fixture, 0 "ignored null byte" warnings,
0 findings, exit 0.

* fix(#604): sweep get-shit-done refs introduced by merging next

The branch was updated with next (#614/#384/#618 etc.), which reference the
get-shit-done/ dir (still named that on next). Swept the stale references in
the merged files to gsd-core so the rename stays consistent and lint:legacy-name
passes:
- commands/gsd/discuss-phase.md (runtime-launcher shim paths)
- src/core.cts (getAgentsDir layout comments)
- tests/bug-384-agents-runtime-aware.test.cjs (require path to runtime lib)

Verified: guard 0 violations; build green.

* fix(#604): exclude gsd-core/ path segments from bug-3683 command cross-ref invariant

The #614 runtime-launcher shim added to discuss-phase.md references
`${_GSD_RUNTIME_ROOT}/gsd-core/bin/...`. bug-3683's REF_PATTERN excluded path-y
refs only via lookbehind, but `}` precedes `/gsd-core/` in the shim, so it
mis-read the directory path as a dangling `/gsd-core` command ref (same class as
the #604 bug-2954 fix). Added a trailing `(?![\w-]*\/)` so `/gsd-<x>/...` path
segments are not treated as slash-command references.

Verified locally on BOTH platforms before pushing:
- mac (node 26) full suite: 0 failures
- gsd-test-runner (linux, node22 image) full suite: 0 failures
- bug-3683 + bug-2954 pass.

* fix(#604): lazily resolve findProjectRoot in gsd-tools (harden flaky CI)

CI intermittently failed state.test's gsd-tools subprocess with
"findProjectRoot is not a function" (flip-flopping across legs; not reproducible
on mac full suite, gsd-test linux full suite, test:unit, or state.test x8).
findProjectRoot is a re-export from core.cjs (sourced from project-root.cjs);
binding it via destructure at module-load can be undefined under a load-ordering
edge. Resolve it lazily at call time via a small wrapper so the lookup happens
after core.cjs is fully initialized.

Verified green on BOTH platforms before pushing:
- mac (node 26) full suite: 0 failures
- gsd-test-runner (linux, node22) full suite: 0 failures
- state.test.cjs: 106/106; gsd-tools loads cleanly.

* fix(#604): allowlist verification-patterns.md placeholder examples in secret scan

The rename git-mv'd references/verification-patterns.md into gsd-core/, pulling
it into the secret-scan diff. It documents stub/placeholder RED-FLAG env-var
examples (illustrative Stripe test-key / database-URL / API-key placeholders) —
not real credentials. Added it to .secretscanignore with the strict annotation,
mirroring the existing gsd-core/workflows/plan-phase.md exception.

Verified locally: secret-scan-lint --strict OK; secret-scan --diff origin/next
exits 0 with 0 findings.

# MVP Concepts — index
Cross-reference for the six MVP-related reference files. Each file has a single, narrow purpose. This index exists so future readers (and agents resolving `@`-refs) can find the right file without grepping the directory.
Canonical domain terms for the concepts named below live in [CONTEXT.md](../../CONTEXT.md) under "Domain terms" — start there if you need a precise definition.
## File map
| File | Purpose | Loaded by |
|---|---|---|
| `references/planner-mvp-mode.md` | **Rules.** Vertical-slice planning rules, slice ordering, Walking Skeleton constraints. | `gsd-planner` agent when `MVP_MODE=true` |
| `references/skeleton-template.md` | **Template.** Shape of `SKELETON.md` for new-project Phase 1 under `--mvp`. | `gsd-planner` agent when the Walking Skeleton gate fires |
| `references/user-story-template.md` | **Template.** Format and slot definitions for `As a / I want to / So that`. | `gsd-mvp-phase` workflow during interactive prompting; `gsd-planner` when emitting the `## Phase Goal` header |
| `references/spidr-splitting.md` | **Splitting discipline.** Five-axis decomposition (Spike, Paths, Interfaces, Data, Rules) for stories too large for one phase. | `gsd-mvp-phase` workflow when the user story exceeds size threshold |
| `references/execute-mvp-tdd.md` | **Gate.** MVP+TDD runtime gate semantics: when it fires, what it checks, halt-and-report protocol, end-of-phase blocking escalation, Behavior-Adding Task definition. | `gsd-executor` agent when `MVP_MODE=true && TDD_MODE=true` |
| `references/verify-mvp-mode.md` | **UAT framing.** Three-section UAT structure (user-flow → technical → coverage), anti-patterns, `User Flow Coverage` section in VERIFICATION.md. | `gsd-verifier` agent when the phase under verification has `mode: mvp` |
## Concept-to-file map
If you're looking for the canonical statement of a concept, this is where to find it:
- **MVP Mode resolution chain** — `workflows/plan-phase.md` Step 1 (CLI flag → roadmap → config → false). Mirrored in `execute-phase.md` and `verify-work.md`.
- **`**Mode:** mvp` parser** — `gsd-core/bin/lib/roadmap.cjs` (`searchPhaseInContent` + `cmdRoadmapAnalyze`). Workflows compare against the parser output, never re-parse.
- **User Story regex** — `/^As a .+, I want to .+, so that .+\.$/` — applied at runtime by `gsd-verifier` (the user-story-format guard) and `gsd-mvp-phase` (interactive validation).
- **Behavior-Adding Task predicate** — `references/execute-mvp-tdd.md` (the canonical three-check definition). Applied at runtime by `gsd-executor`.
- **Walking Skeleton gate condition** — `workflows/plan-phase.md` (Phase 1 + new project + `--mvp` + no prior summaries → emit `SKELETON.md`).
- **MVP+TDD Gate** (RED→GREEN enforcement) — `references/execute-mvp-tdd.md`.
- **MVP-mode UAT framing** (user-flow first, technical deferred) — `references/verify-mvp-mode.md`.
- **Per-phase mode authoring** — `workflows/mvp-phase.md` (writes `**Mode:** mvp` to ROADMAP.md after collecting the user story).
- **Project-wide mode prompt at init** — `workflows/new-project.md` (Vertical MVP vs Horizontal Layers question).
## Interactions worth knowing
- **`--mvp` and `--prd <file>` together on Phase 1.** Both paths converge at the planner spawn. The PRD express path creates `CONTEXT.md` from the PRD file and continues to the research step; the Walking Skeleton gate fires independently when Phase 1 + new project + `--mvp`. The planner therefore receives both `WALKING_SKELETON=true` and PRD-derived context. This is intentional: the PRD informs what the skeleton should prove.
- **`MVP_MODE` is all-or-nothing per phase, not per task.** A phase is either MVP-mode or standard. Mixed-mode phases are not supported (PRD #2826 Q1).
- **`TDD_MODE` is independent of `MVP_MODE`.** TDD can be on without MVP, MVP can be on without TDD. Only the *intersection* (both true) activates the MVP+TDD Gate.
- **The `gsd-roadmapper` agent makes the MVP/standard decision once at project init** based on `PROJECT_MODE`. Per-phase opt-in/out happens later via `/gsd:mvp-phase` or `/gsd-edit-phase`.
## Tests
Structural contract tests for each integration site live under `tests/`:
- `plan-phase-mvp-flag.test.cjs` — plan-phase MVP_MODE resolution chain
- `planner-mvp-mode.test.cjs` — gsd-planner agent MVP section
- `mvp-phase-command.test.cjs`, `mvp-phase-integration.test.cjs`, `mvp-phase-spidr.test.cjs` — `/gsd:mvp-phase`
- `execute-mvp-tdd-gate.test.cjs`, `executor-mvp-tdd-section.test.cjs` — MVP+TDD Gate
- `verifier-mvp-section.test.cjs`, `verify-mvp-uat.test.cjs` — verifier UAT framing
- `new-project-mvp-prompt.test.cjs` — mode prompt at init
- `progress-mvp-display.test.cjs`, `stats-mvp-display.test.cjs`, `graphify-mvp-viz.test.cjs` — discovery surfaces
