Jeremy McSpadden 77c7b4fc9d fix(#1522): enforce canonical verification before phase transition (#1548) 
* fix: require fresh phase verification before transition

* no-mistakes(review): Fix canonical verification closeout gates

* no-mistakes(review): Fix verify-work frontmatter promotion command

* no-mistakes(review): Fix stale verification gates

* no-mistakes(review): Fix canonical verification routing gates

* no-mistakes(review): Fix verification dependency and runtime routing gates

* no-mistakes(review): Block stale verification bypasses

* fix: handle large init manager outputs in verification workflows

* chore: update changeset pr number

* fix(verify-work): use fresh verification.status for stale gate

The stale check after UAT used phase_completion.verification_status from
session-start INIT while human_needed promotion already queried fresh
verification.status. Align the stale gate with the canonical query so
mid-session verification refresh is not ignored.

* fix(init): skip roadmap-checked phases when selecting next_phase

Roadmap-only phases without a disk directory were still promoted to
next_phase when their checkbox was already checked. Exclude
checkboxComplete phases so progress routing does not point at work the
roadmap already marks done.

* fix: gaps_found not overridden by stale, transition uses canonical verification

- verification.cts: check gaps_found before stale so gap-closure routing
  is not masked by a newer summary mtime
- phase.cts: remove redundant findStaleVerificationSummary — readVerificationStatus
  already handles stale detection
- transition.md: replace raw grep on file content with verification.status query
  to avoid false-positive blocks from body text matching

* ci: retrigger tests after rebase

* fix(transition): replace gsd_run advisory check with awk frontmatter extraction

The runtime launcher is not defined until the update_roadmap_and_state step
bash block (~line 165). The early verify_completion block used gsd_run to
query verification.status, which violated the runtime-launcher-parity test:
'preamble appears AFTER the first gsd_run reference'.

Replace the gsd_run call with an awk-based frontmatter extractor that reads
only the status: field between the two --- fences. This avoids both the
preamble-ordering constraint and the original false-positive grep bug where
body text like 'previous_status: gaps_found' would match a full-text regex.

The phase.complete gate at update_roadmap_and_state is the canonical
enforcement point; this early check is advisory only.

Also update workflow-size-baseline.json for the updated transition.md size.

Fixes: runtime-launcher-parity test (B)

* fix: re-check verification under planning lock in phase complete

Move readVerificationStatus into withPlanningLock so stale verification
cannot slip through when a SUMMARY.md is written between the gate and
the roadmap/state mutation. Return the blocked status from the lock
callback and emit the error after release to avoid leaving .lock behind.

* fix(transition): gate on canonical verification.status including stale

Replace awk frontmatter read with verification.status query so transition
blocks when summaries are newer than VERIFICATION.md, matching phase.complete
and other workflows (autonomous, progress, verify-work).

* Fix workflow verification gates for yolo transition and stale routing

Require VERIFY_STATUS passed before yolo/interactive transition advance.
Route stale verification recovery to verify-work, matching canonical projection.

* fix(transition): use verification.status query for stale-aware advisory check

The awk-based check read raw frontmatter status: passed, which misses the
stale case where summaries are newer than the VERIFICATION.md file even
though the frontmatter still says passed. The stale status is computed from
file modification times, not stored in frontmatter.

Move the preamble to the verify_completion bash block (the first block with
a gsd_run call) so gsd_run query verification.status can be used for the
advisory check. This gives the full readVerificationStatus logic including
mtime-based staleness detection, matching the enforcement gate at phase.complete.

Capture full JSON (VERIFY_JSON) so next_action can be included in the
advisory output alongside the status.

Also update workflow-size-baseline.json for the updated transition.md size.

* fix(transition): restore awk frontmatter extraction for pre-shim verification check

The gsd_run launcher shim is not defined until line ~163 of transition.md,
so the verification debt check at line ~80 cannot use gsd_run. Restore the
awk-based frontmatter extraction that correctly reads status without needing
the runtime, and restore the shim at its proper location before
phase.complete.

* fix(#1522): guard findStaleVerificationSummary FS calls + thread opts.fs seam (review)

Address review blocker B1 on #1548: findStaleVerificationSummary ran fs.readdirSync
and two fs.statSync calls unguarded between readVerificationStatus's try/catch sections,
so a TOCTOU race (a SUMMARY listed by scanPhasePlans then removed before statSync) or any
FS error threw uncaught into callers NOT under the planning lock (init.manager /
init.progress / uat-predicate). Wrap the body in try/catch degrading to 'not stale', and
thread the injectable opts.fs seam (add statSync to FsLike, pass fsImpl from the caller)
for parity with readVerificationStatus's no-throw contract and testability. Also adds the
Verification Module glossary entry to CONTEXT.md (review B3).

## Glossary — Domain modules and seams
### Milestone Module
Module owning `milestone complete` (archive roadmap/requirements/phases, build MILESTONES.md entry, update STATE.md), `requirements mark-complete` (checkbox + table update with regex-global-state fix), and `phases clear`. Key behaviors: milestone-phase scoping (extract phases from ROADMAP.md milestone slice, support project-code-prefix dirs e.g. CK-01-name, exclude prior-milestone phases), milestone-archive layout (resolve phase dirs from `.planning/milestones/v*-phases/` when `.planning/phases/` absent), fenced-code-block boundary tracking in `extractCurrentMilestone`. Source of truth: `gsd-core/bin/lib/milestone.cjs` (query handlers for `milestone.complete`, `phases.archive`). Test consolidation: PR #3753 (10 files → 4). (The SDK milestone surface and `GSD.run()` milestone runner were retired with the SDK package per ADR-0174.)
### Dispatch Pipeline Module
Module that composes Dispatch Policy Module, Query Execution Policy Module, and per-stage handlers (input-validation, plan, execution, result-builder, formatting, error-mapping, observability) into the end-to-end pipeline that produces a `QueryDispatchResult`. The SDK-era pipeline collapsed onto the Command Routing Hub per ADR-0174; current dispatch seam: `gsd-core/bin/lib/command-routing-hub.cjs` (see Command Routing Hub below).
### Phase Id Module
Module owning the pure phase-id parsing and matching helpers: phase-name normalization, phase-token extraction/matching, milestone- and phase-dir id parsing, and phase-markdown regex builders (`escapeRegex`, `normalizePhaseName`, `comparePhaseNum`, `extractPhaseToken`, `phaseTokenMatches`, `phaseMarkdownRegexSource`/`phaseMarkdownRegexSourceExact`, `getMilestoneFromPhaseId`, `getPhaseDirFromPhaseId`). Pure string/regex — no I/O, no config, no other core dependency. Extracted from the Core module per ADR-857 rollout phase 2a (#865) as the cycle-free leaf that unblocks the roadmap-parser and phase-locator extractions; the `core.cjs` re-export spine was retired in epic #1267, so callers import this leaf directly. Source of truth: `gsd-core/bin/lib/phase-id.cjs` (generated from `src/phase-id.cts`).
### Phase Lifecycle Module
Module owning phase create, rename, complete, remove, list, and plan-index operations, plus phase-dir prefix validation, STATE.md staleness detection, and auto-prune behaviour. Entry point: `gsd-core/bin/lib/phase.cjs` (CJS surface). Typed phase events: `GSDPhaseStartEvent`, `GSDPhaseStepStartEvent`, `GSDPhaseStepCompleteEvent`, `GSDPhaseCompleteEvent`. (The SDK native-query surface, the `types.ts` event definitions, `phase-runner.ts`, and `phase-prompt.ts` were retired with the SDK package per ADR-0174.)
### Verification Module
Module owning the canonical phase-verification status projection shared by phase transition, progress, manager, autonomous, and closeout readiness paths. `readVerificationStatus(phaseDir, opts?)` reads the first `*-VERIFICATION.md` frontmatter `status`, maps it through `VERIFICATION_ROUTING_TABLE`, and fail-closes — only `{passed}` satisfies the canonical gate; `missing`/`unknown`/`gaps_found`/`human_needed`/`stale` all route away from "complete" (#1522). `findStaleVerificationSummary` flags a SUMMARY newer than the VERIFICATION file (status `stale`). Both honor a no-throw, degrade-to-safe contract (any FS error → `missing` / not-stale) and an injectable `opts.fs` seam. Source of truth: `gsd-core/bin/lib/verification.cjs` (generated from `src/verification.cts`).
### Phase Locator Module
Module owning phase-directory search and location: active-phase discovery against the `.planning/phases/` tree (`searchPhaseInDir`, `findPhaseInternal`) and archived-phase-dir enumeration (`getArchivedPhaseDirs`), matching phase ids/tokens against the filesystem. Depends only on leaf modules (`phase-id` for token/name matching, `core-utils` for fs-scan/path helpers, `planning-workspace` for `planningDir`) — no `loadConfig`, no other core dependency. Extracted from the Core module per ADR-857 rollout phase 2d (#881); the `core.cjs` re-export spine was retired in epic #1267, so callers import this leaf directly. Source of truth: `gsd-core/bin/lib/phase-locator.cjs` (generated from `src/phase-locator.cts`).
### Dispatch Policy Module
Module owning dispatch error mapping, fallback policy, timeout classification, and CLI exit mapping contract.
Canonical error kind set:
- `unknown_command`
- `native_failure`
- `native_timeout`
- `fallback_failure`
- `validation_error`
- `internal_error`
### Command Definition Module
Canonical command metadata Interface powering alias, catalog, and semantics generation.
### Query Runtime Context Module
Module owning query-time context resolution for `projectDir` and `ws`, including precedence and validation policy used by query adapters.
### Native Dispatch Adapter Module
Adapter Module that satisfies native query dispatch at the Dispatch Policy seam, so policy modules consume a focused dispatch Interface instead of closure-wired call sites.
### Query CLI Output Module
Module owning projection from dispatch results/errors to CLI `{ exitCode, stdoutChunks, stderrLines }` output contract.
### STATE.md Document Module
Module owning STATE.md parse, field extraction, field replacement, status normalization, and frontmatter reconstruction. It does not scan `.planning/phases` and does not own persistence or locking; phase/plan/summary counts arrive from inventory/progress Modules as inputs, and read-modify-write paths remain Adapters. Source of truth: `gsd-core/bin/lib/state-document.cjs`.
### Query Execution Policy Module
Module owning query transport routing policy projection (`preferNative`, fallback policy, workstream subprocess forcing) at execution seam.
### Query Subprocess Adapter Module
Adapter Module owning subprocess execution contract for query commands (JSON/raw invocation, `@file:` indirection parsing, timeout/exit error projection).
### Query Command Resolution Module
Canonical command normalization and resolution Interface (`query-command-resolution-strategy`) used by internal query/transport paths after dead-wrapper convergence.
### Command Topology Module
Module owning command resolution, policy projection (`mutation`, `output_mode`), unknown-command diagnosis, and handler Adapter binding at one seam for query dispatch.
### Init Command Module
Module owning the `init.*` family of query handlers that compose atomic queries into the flat JSON bundles consumed by init workflows (`/gsd-execute-phase`, `/gsd-plan-phase`, `/gsd-verify-work`, `/gsd-new-project`, `/gsd-manager`, `/gsd-progress`, `/gsd-resume`, etc.). Source of truth: `gsd-core/bin/lib/init.cjs` — the basic handlers (plus `withProjectRoot` project-identity injection) and the 3 heavyweight handlers (`initNewProject`, `initProgress`, `initManager`). All handlers return `{ data: <flat JSON> }`. Test seams: `tests/init.test.cjs` and `tests/init-manager.test.cjs` (cover withProjectRoot precedence, progress/manager precedence regression #2674, workstream scoping regression #3196, and cross-milestone dependency regression #2267). (The SDK `handlers/init/*.ts` sources and the `init*.test.ts` seams were retired with the SDK package per ADR-0174.)
### Command Routing Hub
Single dispatch seam (`gsd-core/bin/lib/command-routing-hub.cjs`) that centralizes CJS routing, the no-throw pure-result contract, typed error variants, and dispatch-event emission for all command family adapters. Interface: `createHub({ cjsRegistry, manifest, logger }) → hub`; `hub.dispatch({ family, subcommand, args, cwd, raw, parentTraceId? }) → Result` where `Result = { ok: true, data } | { ok: false, kind, ...typedPayload }` and `kind ∈ { UnknownCommand, InvalidArgs, HandlerRefusal, HandlerFailure }`. The `InvalidArgs` variant carries an optional `exitReason?: string` field (amendment #1642 / #1644 Phase 1) holding the `ERROR_REASON` enum value, separate from `reason` (the explanation text); the `makeInvalidArgs(arg, reason, exitReason?)` factory omits the field when the third arg is absent, undefined, or empty — preserving the strict-keys invariant tested at `tests/command-routing-hub.test.cjs:444`. The Hub is single-runtime (no mode selection, no sdkLoader), never prints, never exits, never throws. Adapters call `createHub`, dispatch, then translate the pure Result to `output()`/`error()` calls; when an `InvalidArgs` Result carries `exitReason`, the adapter passes it as the second arg to `error(message, exitReason)` so the JSON-error envelope (`GSD_JSON_ERRORS=1`) preserves the typed reason. Source: `gsd-core/bin/lib/command-routing-hub.cjs`; ADR: `docs/adr/0174-retire-gsd-sdk-package-boundary.md` (§5 amended #1642).
### Runtime Source Layout Module
Single-runtime seam layout for this repository after SDK retirement. Runtime execution paths live under `gsd-core/bin/lib/` and are grouped by seam concern (dispatch, manifest, handlers, runtime, observability, installer). ADR-0174 preserves the seam vocabulary and defines the canonical long-term shape as a seam-aligned TypeScript `src/` tree (`src/dispatch/`, `src/handlers/`, `src/errors/`, `src/manifest/`, `src/config/`, `src/state/`, `src/workstream/`, `src/runtime/`, `src/cli/`, `src/observability/`) compiled to CJS.
### Runtime Launcher Module
Canonical space-safe shell preamble (`gsd_run`) used by every workflow bash block to invoke the GSD runtime CLI. Resolves `gsd-core/bin/gsd-tools.cjs` via `node` when present, falls back to a `gsd-tools` binary on PATH, else errors. Single source of truth: `gsd-core/workflows/_runtime-launcher.snippet.sh`; propagated by `scripts/sync-runtime-launcher.cjs`; enforced by `tests/runtime-launcher-parity.test.cjs`. Replaced the retired unquoted `$GSD_SDK` variable (#373). `gsd_run` is also shipped as a standalone executable (`gsd-core/bin/gsd_run`) via the npm `bin` field; on runtimes that run each fenced bash block in a fresh shell (e.g. Claude Code), the per-file preamble appends the bin directory to `CLAUDE_ENV_FILE` so `gsd_run` resolves from PATH in later blocks — the inline function definition remains the fallback for all other runtimes.
### Dispatch Observability Module
Module owning dispatch-event creation, redaction, and logger behavior for the Command Routing Hub. Core files: `gsd-core/bin/lib/observability/event.cjs`, `gsd-core/bin/lib/observability/logger.cjs`, `gsd-core/bin/lib/observability/redaction.cjs`. Contract: silent on success by default, structured JSON to stderr on error, and opt-in audit trail at `.planning/.gsd-trace.jsonl` via `GSD_AUDIT=1` or config (`audit.enabled`). Each dispatch carries a `traceId`; composed dispatches set `parentTraceId` for correlation.
### Query Pre-Project Config Policy Module
Module policy that defines query-time behavior when `.planning/config.json` is absent: use built-in defaults for parity-sensitive query Interfaces, and emit parity-aligned empty model ids for pre-project model resolution surfaces.
### Configuration Module
Module owning legacy-key normalization, defaults merge, and explicit on-disk migration for `.planning/config.json`. Interface: `normalizeLegacyKeys(parsed) → { parsed, normalizations[] }` (idempotent, pure, returns the list of normalizations applied), `mergeDefaults(parsed) → MergedConfig` (deep-merge of parsed config over canonical defaults), `migrateOnDisk(cwd) → MigrationReport` (explicit, opt-in, called by the installer and by `gsd-tools migrate-config`). Invariants: legacy top-level keys (`branching_strategy`, `sub_repos`, `multiRepo`, `depth`) are normalized into their canonical nested locations in the returned value; defaults come from the shared `gsd-core/bin/shared/config-defaults.manifest.json`; schema (`VALID_CONFIG_KEYS`, `RUNTIME_STATE_KEYS`, `DYNAMIC_KEY_PATTERNS`) comes from `gsd-core/bin/shared/config-schema.manifest.json`. Note: `loadConfig` (project config read + merge) was extracted to the Config Loader Module (`config-loader.cjs`) per ADR-857 phase 2e (#885); `configuration.cjs` now provides only the pure normalization and defaults primitives that `config-loader.cjs` depends on. Source of truth: `gsd-core/bin/lib/configuration.cjs`, consumed via `bin/lib/config-loader.cjs` and `bin/lib/config-schema.cjs`. Eliminates the recurring #3523-class drift bug structurally.
### Planning Workspace Module
Module owning `.planning` path resolution, active workstream pointer policy (`session-scoped > shared`), pointer self-heal behavior, and planning lock semantics for workstream-aware execution.
### Workstream Inventory Module
Module owning workstream directory discovery, per-workstream state projection, phase/plan/summary counting, roadmap-declared phase count, active marker projection, and active-workstream collision inputs. Command handlers render list/status/progress outputs from this inventory instead of rescanning `.planning/workstreams/*` directly. Source of truth for the pure projection is `gsd-core/bin/lib/workstream-inventory-builder.cjs` (a Builder Module); the Reader Adapter `gsd-core/bin/lib/workstream-inventory.cjs` collects filesystem inputs and delegates projection to the Builder.
### Project-Root Resolution Module
Module owning project-root resolution from any starting directory. Walks the ancestor chain (bounded by `FIND_PROJECT_ROOT_MAX_DEPTH = 10`) applying five heuristics in order: (0) own `.planning/` guard (#1362), (1) parent `.planning/config.json` `sub_repos` traversal, (2) legacy `multiRepo: true` boolean + ancestor `.git`, (3) `.git` heuristic with parent `.planning/`, (4) nearest-ancestor `.planning/` walk-up (#1414, epic #1411) — a last-resort second walk (same depth bound, stops at `os.homedir()`) that anchors a plain descendant subdirectory of a single-repo project to its nearest ancestor `.planning/` instead of degrading to defaults; ordered after (1)–(3) so `sub_repos`/`multiRepo` resolution always wins (the Resolution Provenance deterministic-anchoring rule). Returns `startDir` when no ancestor qualifies. Sync `node:fs` I/O. Source of truth: `gsd-core/bin/lib/project-root.cjs`; the `core.cjs` re-export spine was retired in epic #1267, so callers import this leaf directly.
### Planning Path Projection Module
Module owning projection from project/workstream context to concrete `.planning` paths. Policy precedence is `explicit workstream > env workstream > env project > root`. Invalid workspace context is a validation error at this seam rather than a silent fallback.
### Resolution Provenance
Cross-seam principle (ADR-1411, epic #1411): context resolution — config loading, project-root anchoring, workstream resolution — must report its provenance, not fall open silently to defaults. A resolver anchors deterministically to the project root (one walk-up module, no dependence on an arbitrary descendant cwd), returns *what* it resolved **and** *where it came from* (`source`/`degraded`), and surfaces a diagnostic when a *configured* input resolves empty (`not configured` and `configured-but-empty` are distinguishable). The resolution-side analog of ADR-227 (input-validation shape). Target seams: Config Loader Module (`loadConfig` → `ConfigResolution { config, source, degraded }`), Project-Root Resolution Module (single nearest-`.planning/` walk-up, retiring ad-hoc resolvers like `resolvePlanningCwd`), I/O Module (`Resolution<T> { value, configured, reason, warnings }` output envelope). A configured input resolving empty without a reason is a CI-guarded regression. **P1 (nearest-.planning/ heuristic) shipped in #1413; P2 (loadConfigResolved + agent-skills diagnostic) shipped in #1415 / closes #1366**: `loadConfigResolved` now implements the Config Loader seam target; `cmdAgentSkills` uses `findProjectRoot` + `loadConfigResolved` and emits `configured`/`reason`/`source`/`degraded` in its `--json` IR.
### Resolution Convention
Diagnostic-output convention for the Resolution Provenance principle (ADR-1411 P3, #1416). Config-interpreting read verbs expose `Resolution<T> { value, configured, reason, warnings }` (`src/resolution.cts`); agent-skills is the first adopter, where `value = { block, skills_count }` and `source`/`degraded` remain config-provenance extras outside the envelope. Other read verbs expose at least `warnings[]` (e.g. capability-state `{ runtimeConfigDir, capabilities, warnings? }`) without `configured`/`reason`, which are meaningful only for config-interpreting verbs. Mutation verbs expose `warnings[]` (advisory) PLUS `errors[]` (operation-not-applied), e.g. capability-writer `{ capabilities, warnings, errors }`. The shared seam across all shapes is `warnings: string[]`; a single generic `Resolution<T>` across read+write verbs was rejected by the deletion test (`configured`/`reason` are meaningless for capability verbs; `errors[]` cannot fold into `warnings[]`) — ADR-1411 P3 amendment. Recurrence prevention is delivered by P4's CI guard (a configured input resolving empty must carry a `reason`), not by a shared envelope. A CI guard (`scripts/lint-resolution-provenance.cjs`, wired into `lint:ci`) enforces that every registered config-interpreting read verb keeps a `configured_empty`/`not_configured` contract test; the registry in that script is the registration point for future verbs (ADR-1411 P4 / #1417).
### Worktree Safety Policy Module
CJS Module owning worktree lifecycle safety policy for the GSD orchestration layer. Interface: `resolveWorktreeContext(cwd, deps) → WorktreeContext` (linked-worktree root mapping), `parseWorktreePorcelain(output) → WorktreeEntry[]` (porcelain parser, skips detached HEAD), `planWorktreePrune(repoRoot, opts, deps) → PrunePlan` (metadata-prune plan, never destructive by default), `executeWorktreePrunePlan(plan, deps) → PruneResult` (executes prune; degrades gracefully on git timeout), `listLinkedWorktreePaths(repoRoot, deps) → LinkedPathsResult`, `inspectWorktreeHealth(repoRoot, opts, deps) → HealthResult` (orphan + stale detection), `snapshotWorktreeInventory(repoRoot, opts, deps) → InventoryResult`, `planWorktreeWaveCleanup(repoRoot, manifest) → CleanupPlan` (manifest-scoped, fail-closed), `executeWorktreeWaveCleanupPlan(plan, deps) → CleanupResult`, `planWorktreeRecordAgent(manifestRaw, fields) → RecordAgentPlan` (write-strict per-agent manifest append; validates each field at write time via the same `normalizeCleanupManifestEntry` rules the reader enforces; fail-closed on a missing/garbled field or a duplicate `(worktree_path, branch)` the reader would dedup away), `cmdWorktreeRecordAgent(cwd, args, deps) → RecordAgentCmdResult` (thin deps-injectable IO wrapper for the `worktree record-agent` verb). Source of truth: `gsd-core/bin/lib/worktree-safety.cjs`. Timeout path: all git subprocess calls are bounded; callers receive `ok:false, reason:'git_timed_out'` rather than a thrown exception. Test anchor: `tests/worktree-safety.test.cjs`. The `core.cjs` re-export spine was retired in epic #1267: this module absorbed the two thin compositional wrappers that squatted in Core — `resolveWorktreeRoot(cwd, deps)` (a projection over `resolveWorktreeContext`) and `pruneOrphanedWorktrees(...)` (sequences `planWorktreePrune` + `executeWorktreePrunePlan` with a timeout warning) — so callers reach this single worktree-lifecycle seam directly. `gitWorktreeInfoInternal` did NOT move here — worktree-info detection belongs to the Git Query Module.
### Worktree Lifecycle Module
Workflow contract seam covering agent worktree lifecycle orchestration rules. The `worktree_branch_check` block lives in one canonical fragment (`gsd-core/references/worktree-branch-check.md`) that `execute-phase.md`, `quick.md`, `diagnose-issues.md`, and `execute-plan.md` embed at dispatch. Key invariants: `worktree_branch_check` is **verify-only and fail-closed** — the orchestrator owns worktree lifecycle and base recovery, so the sub-agent holds no state-correction primitives; HEAD attachment verified via `git symbolic-ref`; positive allow-list `^worktree-agent-*` enforced; `git update-ref` on protected refs is prohibited; on base mismatch the sub-agent halts with `exit 42` and surfaces to the orchestrator (#48); the orchestrator runs a cwd-drift guard at `execute_waves` entry that resolves the worktree root and refuses drift into an agent worktree (#48); cleanup is manifest-scoped (`WAVE_WORKTREE_MANIFEST`) not global-discovery-based; worktree spawning is sequential (one `run_in_background` at a time to avoid `config.lock` contention). Test anchor: `tests/worktree.test.cjs`.
### Worktree Root Resolution Adapter Module
Adapter Module owning linked-worktree root mapping and metadata-prune policy (`git worktree prune` non-destructive default) for planning/workstream callers.
### Git Query Module
Module owning bounded, never-throw git repository introspection — the single seam for read-only git queries that degrade gracefully rather than throwing. **Adapter 1 — base-branch detection** (`gsd_run query git.base-branch`): Implements a full precedence ladder: (1) `git.base_branch` config override from `.planning/config.json`; (2) `git symbolic-ref --short refs/remotes/origin/HEAD`; (3) `git remote show origin` HEAD branch (authoritative when origin/HEAD is unset — the common case for `git init + remote add + fetch` without `set-head`); (4) local branch existence (`master` present and `main` absent → `master`; `main` present → `main`); (5) `"main"` last-resort default. All git subprocesses are bounded with timeouts (5–15 s) and degrade gracefully to the next tier; the function never throws. Replaces duplicated per-workflow bash detection that silently fell through to `:-main` on master repos (#1146). **Adapter 2 — worktree-info detection**: `gitWorktreeInfoInternal` (`git rev-parse --is-inside-work-tree` + `--show-toplevel`), absorbed from the Core module when the `core.cjs` re-export spine was retired and aligned to this module's bounded-timeout / degrade-don't-throw convention (worktree-info detection is a query concern, distinct from the Worktree Safety Policy Module's lifecycle policy). Source: `src/git-base-branch.cts` → `gsd-core/bin/lib/git-base-branch.cjs`. Wired into `execute-phase.md`, `quick.md`, `ship.md`, `complete-milestone.md`, and `pr-branch.md`.
### Runtime Name Policy Module
Module owning runtime identity normalization at runtime-selection seams. Canonicalizes alias signals from env/config (`GSD_RUNTIME`, `.planning/config.json:runtime`) to supported runtime IDs so output emitters and query runtime gates stay consistent across naming variants (for example `codex-app`/`codex-cli` -> `codex`). Sources: `gsd-core/bin/lib/runtime-name-policy.cjs`, alias manifest `gsd-core/bin/shared/runtime-aliases.manifest.json`.
### Installer Migration Authoring Guard Module
Module owning validation for Installer Migration Module records and planned actions. It enforces migration metadata, explicit install scopes, ownership evidence for destructive/config actions, and runtime contract citations for runtime config rewrites before a migration can enter planning or apply.
### Installer Module
Primary installer for all runtimes. Single production file: `bin/install.js` (generated). Exports: `install(isGlobal, runtime[, configDir])` → typed result `{ runtime, configDir, settingsPath, settings, statuslineCommand, updateBannerCommand }`; `uninstall(isGlobal, runtime[, configDir])`; `installRuntimeArtifacts(runtime, configDir, scope, resolvedProfile)`; `uninstallRuntimeArtifacts(runtime, configDir, scope)`; `writeManifest(configDir, runtime)`. Runtime enum: `allRuntimes` (15 values: claude, antigravity, augment, cline, codebuddy, codex, copilot, cursor, gemini, hermes, kilo, opencode, qwen, trae, windsurf). Directory helpers: `getDirName(runtime)` → local dir name; `getConfigDirFromHome(runtime, isGlobal)` → shell-quoted path fragment. Per-runtime global config-dir resolution is delegated to `gsd-core/bin/lib/runtime-homes.cjs:getGlobalConfigDir(runtime[, explicitDir])` — the canonical, env-var–aware projection (`explicitDir` override + opencode/kilo `*_CONFIG` file-path precedence); the legacy in-installer `getGlobalDir`/`getOpencodeGlobalDir`/`getKiloGlobalDir` were retired into it (#56). The same module exposes `detectAntigravityDirAmbiguity(opts)` — a side-effect-free probe reporting whether multiple `~/.gemini/antigravity{,-ide,-cli}` dirs coexist and which one GSD's `gsd-core/VERSION` marker (the `dot-home-nested` `probeExists`) resolves to, for installer / `/gsd-update` operator guidance when a pre-#217 install landed in the wrong sibling dir (#1441). Runtime-specific helpers: `resolveKiloConfigPath(configDir)`, `configureKiloPermissions(isGlobal[, explicitDir])`. Claude-specific permission helpers: `mergeClaudePermissions(settings)` — non-destructively appends GSD-owned allow/deny entries (see `GSD_CLAUDE_ALLOW_PERMISSIONS`, `GSD_CLAUDE_DENY_PERMISSIONS` constants) to a Claude Code settings object; called from `finishInstall` for `runtime === 'claude'` only; uninstall removes exactly these entries (#768). Layout-driven artifact copy/removal delegates to `gsd-core/bin/lib/runtime-artifact-layout.cjs:resolveRuntimeArtifactLayout` (throws `TypeError` for unknown runtimes). Seven runtimes with non-recursive skill loaders (claude global, cline, qwen, hermes, augment, trae, antigravity) use a nested router layout: 6 `gsd-ns-*` router bundles emitted as top-level skills, with concrete skills nested at `<router>/skills/<name>/SKILL.md` (hermes prefix='': `skills/gsd/ns-*/…`). The remaining skills-runtimes (cursor, codex, copilot, windsurf, codebuddy, opencode, kilo) use the flat `skills/gsd-<stem>/` layout unchanged. See Skill Surface Budget Module and Runtime Artifact Layout Module.
### I/O Module
Module owning the tool's CLI I/O primitives: `output()` result emission (with large-payload temp-file spillover via `GSD_TEMP_DIR`/`ensureGsdTempDir`/`reapStaleTempFiles`), `error()` stderr emission with exit-code mapping, and the JSON-error-mode toggle (`setJsonErrorMode`/`getJsonErrorMode`, `ERROR_REASON`). Extracted from the Core module per ADR-857 rollout phase 1 (#859) so feature modules (`graphify`, `intel`, `audit`, `profile-pipeline`) depend on a small I/O seam instead of the core god-module; the `core.cjs` re-export spine was retired in epic #1267, so callers import this leaf directly. Source of truth: `gsd-core/bin/lib/io.cjs` (generated from `src/io.cts`).
### Markdown Sectionizer
Canonical markdown-structure parsing seam (`gsd-core/bin/lib/markdown-sectionizer.cjs`, generated from `src/markdown-sectionizer.cts`). Pure functions, Node built-ins only. Exports: `stripFencedCode(content) → { text, unterminatedFence }` (CommonMark-correct state machine, CRLF-safe, signals unterminated fences); `tokenizeHeadings(content) → HeadingToken[]` (ATX headings outside fenced blocks, `{ level, text, line, offset }`); `collectSections(content, stopPredicate) → Section[]` (line-by-line section collection driven by a heading predicate); `collectSection(content, headingPredicate, { levelBounded, stripFences }) → Section | null` (single named section with level-bounded stop); `iterateBullets(sectionText) → BulletItem[]` (dash/checkbox/numbered markers with indented continuation); `extractTaggedBlocks(content, tagName) → string[]` (inner text of every `<tagName>…</tagName>` block in document order, tagName regex-escaped, caller decides fence-stripping — generalises `decisions.cts`'s bespoke extractor for T1); `replaceSection(content, section, newBody) → string` (pure character-offset splice using `Section.bodyStart`/`bodyEnd` for read-modify-write callers — eliminates T6 `state.cts`'s 7× inline `content.replace` pattern). `Section` carries `bodyStart`/`bodyEnd` offsets for `replaceSection`. ADR-1372 (epic #1372) establishes this seam and a tiered migration plan (T0–T7) to retire the 8+ ad-hoc markdown parsers and ~20 inline section-collects across `src/*.cts`. New `src/*.cts` modules must import this seam instead of hand-rolling fence strippers or heading-regex section walks (enforced by the `no-adhoc-markdown-parsing` ESLint rule landing in tier T7).
### Roadmap Parser Module
Module owning ROADMAP.md parsing: shipped-milestone slicing, current-milestone extraction, milestone/phase lookups, and milestone-phase filtering (`stripShippedMilestones`, `extractCurrentMilestone`, `replaceInCurrentMilestone`, `getRoadmapPhaseInternal`, `getMilestoneInfo`, `getMilestonePhaseFilter`). Depends only on leaf modules (`phase-id`, `planning-workspace`, `shell-command-projection`) — no `loadConfig`, no other core dependency. Extracted from the Core module per ADR-857 rollout phase 2b (#870), resolving the ROADMAP.md parse/write straddle so the Roadmap module (`roadmap.cjs`, which owns ROADMAP.md mutation) imports parsing directly instead of through Core; the `core.cjs` re-export spine was retired in epic #1267, so callers import this leaf directly. Source of truth: `gsd-core/bin/lib/roadmap-parser.cjs` (generated from `src/roadmap-parser.cts`).
### Core Utilities Module
Module owning the shared low-level utility primitives extracted from Core: POSIX path normalization (`toPosixPath`), filesystem scanning (`detectSubRepos`, `readSubdirectories`, `getPhaseFileStats`, `pathExistsInternal`), and small pure helpers (`generateSlugInternal`, `extractOneLinerFromBody`, `filterPlanFiles`, `filterSummaryFiles`, `extractCanonicalPlanId`, `timeAgo`). Depends only on Node built-ins and already-leafed modules (`phase-id` for `comparePhaseNum`, `planning-workspace` for `findContextMdIn`) — no `loadConfig`, no other core dependency. Extracted from the Core module per ADR-857 rollout phase 2c (#877) as the shared leaf that unblocks the phase-locator fs-search extraction (2d); the `core.cjs` re-export spine was retired in epic #1267, so callers import this leaf directly. Source of truth: `gsd-core/bin/lib/core-utils.cjs` (generated from `src/core-utils.cts`).
### Agent Install Check Module
Module owning agent-presence resolution and verification, extracted from the Core module as the cleanup step that retired the `core.cjs` re-export spine (the final ADR-857 decomposition, epic #1267). Interface: `getAgentsDir(runtime?, env?)` — env-var-aware, runtime-aware agents-directory resolution (the `claude` runtime resolves `__dirname`-relative); `checkAgentsInstalled(...)` — multi-runtime agent-presence check that validates `gsd-file-manifest.json` completeness and confirms the declared agents exist on disk. Pure read/verify — no install-write side effects (writes remain the Installer Module's). Consumed by the Init Command Module, the verify workflow, and the docs workflow. Source of truth: `gsd-core/bin/lib/agent-install-check.cjs` (generated from `src/agent-install-check.cts`); replaced the two functions that squatted in `core.cts`. See Installer Module and ADR-857.
### Config Loader Module
Module owning project configuration loading: reads `.planning/config.json`, merges built-in defaults (`CONFIG_DEFAULTS`/`CANONICAL_CONFIG_DEFAULTS`), normalizes legacy keys, applies the active-workstream overlay, validates against the config schema, and warns on unknown keys/profile overrides. Primary interface: `loadConfigResolved(cwd, options) → ConfigResolution { config, source, degraded }` (provenance-aware, ADR-1411 P2 / #1415) — `source` ∈ `'workstream' | 'root' | 'builtin-defaults' | 'global-defaults'`; `degraded:true` when a workstream was requested but its config.json was absent (fell back to root config). `loadConfig(cwd, options) → Record<string,unknown>` is the back-compat thin wrapper over `loadConfigResolved` (byte-identical result). Resolution is **caller-anchored, not loader-anchored**: `loadConfigResolved` resolves `cwd` as-is (no walk-up), so `loadConfig` stays byte-identical for its callers; callers that need cwd-drift tolerance (e.g. `cmdAgentSkills`) anchor to the project root via `findProjectRoot` (Project-Root Resolution Module) *before* calling `loadConfigResolved`. Helper exports: `_deepMergeConfig`, `isGitIgnored`, `_warnUnknownProfileOverrides`. Depends only on leaf modules (`configuration`, `config-schema`, `planning-workspace`, `shell-command-projection`, `core-utils`, `model-catalog`) — no other core dependency. Extracted from the Core module per ADR-857 rollout phase 2e (#885) as the prerequisite for the model-resolver extraction (the resolvers call `loadConfig`); the `core.cjs` re-export spine was retired in epic #1267, so callers import this leaf directly. Source of truth: `gsd-core/bin/lib/config-loader.cjs` (generated from `src/config-loader.cts`).
### Model Resolver Module
Module owning model and effort resolution policy: resolves the model, runtime tier, planning granularity, reasoning effort, and fast-mode for a given agent by reading project config and resolving against the model profiles and catalog (`resolveModelInternal`, `resolveModelPolicy`, `resolveTierEntry`, `resolveModelForTier`, `resolveGranularityInternal`, `resolveEffortInternal`, `resolveFastModeInternal`, `resolveEffortForTier`, `nextEffort`, `assertValidGranularityOverride`). Depends only on leaf modules (`config-loader` for `loadConfig`, `configuration` for defaults, `model-profiles` and `model-catalog` for the static tables) — no other core dependency. Extracted from the Core module per ADR-857 rollout phase 2f (#888) — the final core.cts decomposition step; the `core.cjs` re-export spine was retired in epic #1267, so callers import this leaf directly. Source of truth: `gsd-core/bin/lib/model-resolver.cjs` (generated from `src/model-resolver.cts`).
### Package Identity Module [Planned]
Single seam owning GSD's published-package coordinates so a repoint/rename is a one-line change instead of a tree-wide sweep. Source of truth is `package.json`; values are *derived*, not re-typed: `packageName` (`.name` → `@opengsd/get-shit-done-redux`), `binName` (`Object.keys(.bin)[0]` → `get-shit-done-redux`), `repoSlug` (parsed from `.repository.url` → `open-gsd/get-shit-done-redux`), plus derived `changelogRawUrl` and `manualInstallCommand({ scope, runtime })`. Generated `.cjs` per ADR-457 (generated-single-source); shipped under `gsd-core/bin/lib/`. Three consumer worlds: **Node** consumers `require()` it at runtime (worker, `check-latest-version.cjs`, `bin/install.js`); the **bash launcher** snippet receives the literal injected by `scripts/sync-runtime-launcher.cjs` at sync time; **prose/help** literals (`update.md`, installer help) carry a committed copy. A drift-guard lint (`scripts/lint-package-identity-drift.cjs`, sibling to `check:alias-drift`) fails CI on any raw package/repo literal outside `package.json`, the generated module, and the value-checked materialization sites — this is what keeps the seam real (`two adapters`, not one). Replaces the contradictory pair it consolidates: the runtime-broken `require('../package.json').name` in `hooks/gsd-check-update-worker.js` (#378, resolves to `undefined` post-install) and the hardcoded constant in `check-latest-version.cjs` (#2992). _Avoid_: "package name string", "the npm name" (when you mean the seam). See ADR-457 and Installer Module.
### Update Context Module [Planned]
Module owning install detection for `/gsd:update`. `resolveUpdateContext({ home, cwd, env, fs, preferredConfigDir, preferredRuntime })` is a pure, injected-fs port of update.md's former ~280-line `get_installed_version` bash; it reproduces the full precedence cascade — preferred-config-dir fast path, local-over-global probe with same-path dedup, env-var overrides (`CLAUDE_CONFIG_DIR`, `OPENCODE_CONFIG`, `KILO_CONFIG`, `XDG_CONFIG_HOME`, `CODEX_HOME`, …), and semver validation — and returns the 4-field contract `{ installedVersion, scope, runtime, gsdDir }` (scope ∈ `LOCAL`/`GLOBAL`/`UNKNOWN`). Antigravity is modelled first-class (its `.gemini/antigravity{,-ide,-cli}` dirs probe before bare `.gemini`; #3608). Exposed to the workflow as `gsd-tools update-context [--config-dir <d>] [--runtime <r>] --json`; `loadUpdateContext` wires the real fs. The workflow keeps only the execution_context path → `PREFERRED_*` derivation (the one input it alone knows). Source: `gsd-core/bin/lib/update-context.cjs`; tests: `tests/issue-498-update-context.test.cjs`. See Installer Module and Package Identity Module.
### Skill Surface Budget Module
Module owning which skills and agents are written to runtime config directories at install time (Phase 1) and at runtime via cluster-level toggles (Phase 2). Phase 1: `gsd-core/bin/lib/install-profiles.cjs` defines named profiles (`core`, `standard`, `full`), computes transitive closure over `requires:` frontmatter, stages skills/agents to runtime config dirs, and persists the chosen profile in a `.gsd-profile` marker. Profile resolution precedence: explicit `--profile=` flag > `.gsd-profile` marker > `full`. `--minimal`/`--core-only` are back-compat aliases for `--profile=core`. Phase 2: `gsd-core/bin/lib/surface.cjs` implements the `/gsd:surface` slash command for cluster-level enable/disable without reinstall; cluster definitions live in `gsd-core/bin/lib/clusters.cjs`; per-runtime state persists in `<runtimeConfigDir>/.gsd-surface.json` independent from the `.gsd-profile` marker. See ADR-0011.
### Runtime Artifact Layout Module
Module owning the per-runtime mapping from artifact kind to filesystem placement. ADR-3660 defines the typed `kinds` per runtime (`commands`, `agents`, `skills`) with destination subpath, prefix, and stage adapter (with per-runtime converters in `bin/install.js`: `convertClaudeCommandToClaudeSkill`, `…CodexSkill`, `…CopilotSkill`, `…AntigravitySkill`). Owns the per-runtime `nested` skill-bundle decision (#69): a `skillsKind` flag in `src/runtime-artifact-layout.cts` drives whether a runtime receives the nested router layout (6 `gsd-ns-*` routers + concrete skills under `<router>/skills/<name>/`) or the flat `skills/gsd-<stem>/` layout; the evidence/doc-link matrix is recorded in a comment above `resolveRuntimeArtifactLayout`. Phase 1 applies this seam to the Runtime Surface Module (`surface.cjs:applySurface`); as of #813, `applySurface` applies the same per-runtime skill-body path rewrites as `installRuntimeArtifacts` for `skills` kinds — re-surfacing no longer overwrites installed SKILL.md bodies with converter-default `~/.claude` paths. Per ADR-1508 / #1511 the former `getInstallExports`/`loadInstallExports` relay (a `GSD_TEST_MODE`-guarded `require('bin/install.js')` by which `surface.cjs` reached `computePathPrefix`/`applyRuntimeContentRewritesInPlace`) was DELETED from this module; content rewriting now lives in the Runtime Artifact Conversion Module and `surface.cjs:applySurface` calls its `rewriteStagedSkillBodies` directly. The resolved `scope` is still carried on the `Layout` object so `applySurface` derives the same `pathPrefix` (global `$HOME` form vs. absolute) as a fresh install. Phase 2 is planned to migrate install/uninstall in `bin/install.js` so all lifecycle sites iterate one shared layout table instead of re-encoding runtime layout logic. This design is intended to remove the #3659 class of omissions. Migrations remain under the Installer Migration Module (ADR-0008). See ADR-3660.
### Runtime Artifact Conversion Module
Sibling Module to Runtime Artifact Layout Module. Owns projection from canonical Claude-authored command/agent/skill markdown into runtime-specific artifact bodies, including converter selection, frontmatter/body normalization, runtime path rewrites, and staged artifact generation. Runtime Artifact Layout remains responsible for filesystem placement (`kind`, destination subpath, prefix, nesting); Runtime Artifact Conversion owns the content Implementation behind that placement seam so install, uninstall/surface parity, and future plugin/package projections stop reaching back through `bin/install.js` for converter functions or `GSD_TEST_MODE`-guarded installer exports. Chosen direction: sibling Module, not an expanded Layout Module, to preserve ADR-3660's narrow placement responsibility while deepening artifact content locality. First slice: relocate only the layout-reached conversion family (`convertClaudeCommandTo*Skill`, converted command-file emitters, `buildKimiAgentArtifacts`) plus the minimal helper closure they need; do not leave helper dependencies in `bin/install.js` because that would preserve the same shallow seam under a new filename. Installer integration decision: `bin/install.js` imports the conversion Module at top level and re-exports the moved names for compatibility; the conversion Module must not import `bin/install.js` or Runtime Artifact Layout, so the dependency direction becomes installer/layout Adapters -> conversion Module, never conversion -> installer. First-slice Interface decision: export the existing compatibility names only; do not introduce a grouped `convertRuntimeArtifact` Interface until after relocation proves byte-for-byte behavior. SHIPPED (ADR-1508): the converter family relocated in #1510 Phase 1 (`getDirName`→runtime-name-policy, `processAttribution` here); #1511 Phase 2 moved the content-rewrite engine here in full — `_applyRuntimeRewrites` (per-runtime switch, injected attribution), the staged-content walkers `applyRuntimeContentRewritesInPlace`/`applyRuntimeContentRewritesForCommandsInPlace`, `computePathPrefix` (private; `_computePathPrefix` for tests), and the deep public seam `rewriteStagedSkillBodies`/`rewriteStagedCommandBodies({runtime,configDir,scope,homedir?,platform?,resolveAttribution?})`. `bin/install.js` binds these back (single owner, exports preserved); `getCommitAttribution` stays in `bin/install.js` (impure install-time config I/O) and is injected. The `getInstallExports` relay in Runtime Artifact Layout Module was deleted; the dependency direction installer/layout → conversion (never upward) is now enforced. Exception: opencode and kilo path-prefix rewriting is a deliberate `bin/install.js`-owned pre-conversion step (`applyOpencodeFamilyPathPrefix`) per #784, not a violation of the single-owner rule. Source: `gsd-core/bin/lib/runtime-artifact-conversion.cjs` (generated from `src/runtime-artifact-conversion.cts`). Also exports `resolveVersionFrom(libDir)` — a lazy, defensive GSD-version resolver (installed-tree `gsd-core/VERSION` first, then the source/npm `package.json` three dirs up, both validated against the repo's shared semver-prefix shape, degrading to `''` on failure) that replaced a module-load-time `require('../../../package.json')` which crashed on runtimes whose root carries no `package.json` (e.g. Codex) (#1383).
### Runtime Artifact Install Plan Module
Module owning install-time staging and content-rewrite selection for a pre-resolved Runtime Artifact Layout. Interface: `createRuntimeArtifactInstallPlan({ layout, resolvedProfile, homedir?, platform?, resolveAttribution?, deps? }) -> { ok:true, plan:{ items, cleanupDirs } } | { ok:false, kind:'stage_failed'|'rewrite_failed', message, cleanupDirs, failedKind? }`. It iterates `layout.kinds` in order, calls each kind's `stage(resolvedProfile)`, delegates `commands` to Runtime Artifact Conversion `rewriteStagedCommandBodies`, delegates `skills` and `kimi-agents` to `rewriteStagedSkillBodies`, leaves non-rewritten kinds unchanged, and projects copy items as `{ kind, sourceDir, destDir }`. It deliberately does not prune, copy, run legacy migrations, print output, or execute cleanup; those remain Installer Module adapter responsibilities until later slices wire the plan into `bin/install.js`. Source: `gsd-core/bin/lib/runtime-artifact-install-plan.cjs` (generated from `src/runtime-artifact-install-plan.cts`). See Runtime Artifact Layout Module and Runtime Artifact Conversion Module.
### Command Roster Module
Tiny read-only helper Module owning discovery of canonical `commands/gsd/*.md` command stems for artifact conversion and runtime projection. It is a sibling dependency of Runtime Artifact Conversion Module, not part of conversion itself: conversion consumes a roster to safely rewrite `gsd:` / `/gsd-` references, while roster discovery owns filesystem/catalog knowledge. First slice: extract existing `readGsdCommandNames` behavior behind this Module instead of moving it into Runtime Artifact Conversion Module or keeping it as installer-owned state.
### Runtime Install Policy Module
Projects a pure, typed install plan for a given runtime by composing artifact placements (Runtime Artifact Layout Module), command text (Shell Command Projection Module), and per-runtime config intentions — with no filesystem IO or format-specific serialization. Runtime-specific adapters consume the plan and execute concrete file mutations and config rendering. See ADR-58.
### Capability [Planned]
A bundle delivering one optional GSD feature, toggled as a unit at install or after install. Owns its skills, agents, hooks, federated config-key schema (keys + defaults + validation), and loop extension-point registrations, plus a `requires` list of other Capabilities, plus an optional `activationKey` (a dotted config key, e.g. `graphify.enabled`) naming the config toggle that gates the whole capability — consumed by the Capability State Resolver's per-capability `active` (absent → no config gate; see Capability State Resolver tri-state deepening). Declared co-located in the Capability's own folder and compiled into a generated central Capability Registry at build time. The five-step loop (Discuss → Plan → Execute → Verify → Ship) and shared-infrastructure skills (phase, config, help, update, surface, progress) are the privileged host, not Capabilities, in v1 — but host extension points are data so a loop step can become a Capability under a future uniform kernel. Supersedes the implicit feature-scattering across clusters, install-profiles, and config-schema. Generalizes the Skill Surface Budget Module and Runtime Install Policy Module.
### Loop Host Contract
Generated description of what the five-step loop (Discuss → Plan → Execute → Verify → Ship) exposes as extension points: per-step loop points, agent roles, and core artifacts. Sourced from structured `<!-- gsd:loop-host ... -->` HTML-comment markers embedded near the top of each of the five step workflow files (`discuss-phase.md`, `plan-phase.md`, `execute-phase.md`, `verify-work.md`, `ship.md`). Generated by `scripts/gen-loop-host-contract.cjs` → `gsd-core/bin/lib/loop-host-contract.cjs` (ADR-894 §3 phase 3a-impl-2). Covers exactly the 12 canonical points (discuss:pre/post, plan:pre/post, execute:pre/wave:pre/wave:post/post, verify:pre/post, ship:pre/post). The generator enforces a drift guard: every declared non-orchestrator agent role must correspond to an actual agent reference in the workflow file. Consumed by `gen-capability-registry.cjs` (replaces the former inline `LOOP_HOST_CONTRACT` constant). Run `node scripts/gen-loop-host-contract.cjs --write` after editing a workflow step marker.
### Capability Registry
Generated central manifest projecting all co-located Capability declarations into one validated artifact for runtime resolution and for the install, surface, config, and loop-extension adapters. Mirrors the research-profiles / package-identity generation pattern (co-located source → generated central file). Generated by `scripts/gen-capability-registry.cjs` → `gsd-core/bin/lib/capability-registry.cjs` (ADR-894 §5 phase 3a-impl). Role-partitioned indexes: `bySkill`, `byAgent`, `byLoopPoint` (hook ordering materialized), `configKeys` (ownership map: key→capId), `configSchema` (full per-key schema: key→{ owner, type, default, description }), `runtimes`, `requiresClosure(id)`. Each feature capability's entry in `capabilities` now includes the optional `activationKey` field (the dotted config key that gates the whole capability, e.g. `"graphify.enabled"`; absent means no config gate). ADR-857 phase 3b adds `configSchema` with validated type/default/description per key, sourced from each capability's `.config` slice. ADR-857 phase 4a adds two derived views: `capabilityClusters` (`{ <capId>: [<skill stems>] }` — each cap's skills array, sorted, derived from the capability's `skills` declaration; consistency-gated against the hand-authored `CLUSTERS`) and `profileMembership` (`{ <capId>: { tier, profiles: [...] } }` — the tier-derived index: suffix of `PROFILE_RANK` starting at the capability's tier). Both views cover the same capability set: only capabilities that own skills (non-empty `skills` array). The generator enforces a HARD gate (throws) if a capId matching a `CLUSTERS` key has a mismatched skill set, and emits SOFT `⚠ pending-reconciliation` warnings to stderr (never to the file) for skills not yet in the hand-authored profile at the capability's tier. `install` and `surface` are UNTOUCHED (still read hand-authored constants; derived views are emitted and tested but unconsumed until cutover). Validated against the Loop Host Contract (12 points; generated by `gen-loop-host-contract.cjs` from workflow markers, phase 3a-impl-2). Run `node scripts/gen-capability-registry.cjs --write` after editing any `capabilities/<id>/capability.json`.
### Federated Config
ADR-857 phase 3b seam that merges capability-declared config slices into the `loadConfig` return value. Implemented in `src/federated-config.cts` → `gsd-core/bin/lib/federated-config.cjs`. Exports `mergeFederatedConfig({ configSchema, isCentralKey, userConfig }) → { values, validKeys, warnings }`. Rules: central-schema keys are skipped with a `pending-migration` warning; malformed slices are skipped with a warning (never throws); valid federated keys (absent from the central schema) resolve to the user-supplied value (if type-matches) or the slice default. Object writes are guarded against prototype pollution with inline literal `__proto__`/`constructor`/`prototype` key checks. ADR-857 phase 6 made the channel live for migrated Capability keys: `config-schema.cjs` exposes `isCentralConfigKey()` for central ownership and `isValidConfigKey()` accepts central + runtime + dynamic + Capability-owned registry keys. `loadConfig` exposes `_setFederatedRegistryForTests`/`_resetFederatedRegistryForTests` seams for injecting a synthetic registry in tests.
### Capability Registry Overlay
Runtime seam (`gsd-core/bin/lib/capability-loader.cjs`, ADR-1244 D2) that composes the frozen first-party Capability Registry (`capability-registry.cjs`) with a validated installed overlay of third-party capability manifests discovered at load time. Install roots are global (`$GSD_HOME/.gsd/capabilities/<id>/capability.json`, where `GSD_HOME` defaults to `~`) and project (`<projectRoot>/.gsd/capabilities/<id>/capability.json`). Primary interface: `loadRegistry({ includeInstalled }) → registry` — when `includeInstalled` is true the overlay is merged via the canonical `buildRegistry` so all derived views (bySkill, byAgent, byLoopPoint, configKeys) cover first-party and overlay entries identically. First-party always wins: any overlay entry whose id, owned skill/agent stem, or federated config key collides with first-party, or whose id uses a reserved `gsd-`/`gsd-core-`/`anthropic-` prefix, is rejected at load time. Load-time re-gate: an overlay failing schema validation or whose `engines.gsd` semver range does not satisfy the running GSD version is skipped with a warning and never crashes the load loop. Per-hook-kind policy: a skipped capability that declared a `gate`-kind hook fails CLOSED (the loop resolver injects a blocking gate); skipped `step` or `contribution` capabilities skip open. A capability dir whose co-located ledger entry carries an in-flight `_pending` intent (a crashed/uncommitted install or upgrade, ADR-1244 Phase 4) is skipped OPEN (never activated until reconciliation commits or rolls it back). #1459 user-owned consent gate: a PROJECT-scope overlay is activated (declarative surfaces AND command dispatch) ONLY when the user-owned Capability Consent Store holds a record for `(realpath(projectRoot), id)` whose stored `contentHash` equals the bundle content hash the loader RECOMPUTES at load (`bundleContentHash(capDir)` over the whole on-disk bundle) — NOT the repo-plantable ledger integrity nor the executable-only disclosure signature — otherwise the cap is DISCOVERED-BUT-INACTIVE (a warning carrying `kind:'unconsented'`, no surfaces, empty commandRoots), so a forged/cloned in-repo project ledger or any post-consent tamper no longer activates anything; GLOBAL scope (under the user's own home) is trusted without a record, and the global-vs-project root dedup/escalation is realpath-keyed so a symlinked `GSD_HOME` aliasing the project root cannot bypass the gate (finding 1). The consent lookup is wrapped to fail CLOSED (inactive); both the per-scope ledger AND the `capability.json` manifest are read via the shared bounded `readSmallRegularFile` (a repo-planted FIFO/oversized ledger or manifest can no longer hang or OOM the loader — finding 2). The loader reuses the ledger's shared `isValidLedgerEntry` for committed-entry parity. Consumers wired to the overlay-aware registry: `config-loader.cjs`, `config-schema.cjs`, `capability-state.cjs`, `loop-resolver.cjs`.
### Capability Validator
Shared conformance validator (`gsd-core/bin/lib/capability-validator.cjs`, ADR-1244 D2) extracted from `scripts/gen-capability-registry.cjs` so the build-time generator and the runtime overlay loader share one validator implementation. Exports the same `validateCapability(manifest)` surface consumed by both the generator (build-time) and `capability-loader.cjs` (runtime). Generative-parity is CI-guarded: a drift between the generator's validation logic and the extracted module is a hard failure. Callers that previously inlined validation against the generator's internal helpers are migrated to import this module directly. Source of truth: `gsd-core/bin/lib/capability-validator.cjs`.
### Capability Source Resolver
ADR-1244 D3 fetch-and-stage seam (`gsd-core/bin/lib/capability-source.cjs`). Primary interface: `resolveCapabilitySource(spec, opts) → { id, version, stagedDir, integrity, source }`. Parses specs via `parseSpec` and dispatches to one adapter per source kind: `local` (fs copy from a `./`-prefixed path), `git` (clone `--depth 1` + checkout via `execGit`; https/ssh/git transports only — `ext::` and `file://` are rejected), `npm` (pack via `execNpm --ignore-scripts` + tar extract — NEVER `npm install`, no lifecycle scripts; shell-metacharacter spec rejection for Windows shell safety), `tarball` (HTTPS download + sha512 integrity verify BEFORE extraction + tar extract), and `registry` (explicit stub — no first-party endpoint yet). Security contract: install never executes capability code (copy/extract only); integrity is verified before staging; tar-slip member paths and symlinks are rejected. Staging is atomic: a per-pid/timestamp scratch directory under `.staging/` is renamed into `$GSD_HOME/.gsd/capabilities/<id>/` on success and removed on failure. The Phase 1/2 validator suite runs on the fetched manifest before finalizing; `engines.gsd` is pre-checked. Test seam: `_setCapabilitySourceHttpGet`.
### Capability Ledger
ADR-1244 D4 per-runtime install manifest (`gsd-core/bin/lib/capability-ledger.cjs`). Leaf module (only `node:fs`/`node:path` plus `shell-command-projection`'s `platformWriteSync`). Records `{ id, version, source, integrity, files[], sharedEdits[{file,marker}] }` per installed capability in `.gsd-capabilities.json` at the runtime config dir root. Exports: `readLedger` (structural-validated, never throws), `writeLedger` (atomic via `platformWriteSync`), `recordInstall` (idempotent, prototype-pollution-guarded), `removeEntry`, and `reconcile` (reports orphans whose `files[]` are missing on disk; hardened against non-string/`..` members; never mutates). Serves as the atomic commit point for Phase-4 upgrade/remove and the reconciliation basis for detecting stale entries after out-of-band deletions.
### Capability Consent Store
Issue #1459 user-owned consent seam (`gsd-core/bin/lib/capability-consent.cjs`, generated from `src/capability-consent.cts`). Leaf module (`node:fs`/`node:path`/`node:os`/`node:crypto` + the ledger's shared bounded `readSmallRegularFile`/`readSmallRegularFileBuffer` + the shared `capability-lock` primitive). Stores `{ version:"1", records: { "<JSON disk key {r:realpath(projectRoot),i:id}>": { projectRoot, id, scope:'project', integrity, disclosureSignature, contentHash, consentedAt } } }` at `${GSD_HOME||homedir()}/.gsd/consent.json` — a USER-OWNED file OUTSIDE any repository. Exports: `consentStorePath(gsdHome?)`, `readConsentStore(gsdHome?)` (bounded via `readSmallRegularFile` + 8 MiB cap, NON-THROWING — missing/corrupt/oversized/FIFO/wrong-shape → empty `{records:{}}`; caps records at `MAX_RECORDS=4096`), `bundleContentHash(capDir)` (THE security binding — a `sha512-<base64>` over a DETERMINISTIC, INJECTIVE, LOSSLESS serialization of EVERY regular file AND directory under the bundle: length-FRAMED entry COUNT + per-entry TYPE tag + uint32 path-byte-len + RAW path bytes from a `{encoding:'buffer'}` dir walk [finding 4] + for files uint64 content-byte-len + RAW content bytes via `readSmallRegularFileBuffer` [finding 1b], plus typed DIR markers binding empty directories [finding 2]; symlinks/non-regular rejected; size+count bounded), `hasProjectConsent({gsdHome,projectRoot,id,contentHash})` (true iff a record for `${realpath(projectRoot)}<id>` exists AND its stored `contentHash` equals the supplied recomputed hash — the binding is `contentHash`, NOT `integrity` and NOT `disclosureSignature` (those remain on the record purely for the human disclosure + re-consent-on-executable-change UX); unsafe ids → false; prototype-pollution-safe NUL-joined keys + `Object.prototype.hasOwnProperty`), `recordProjectConsent({gsdHome,projectRoot,id,integrity,disclosureSignature,contentHash})` (LOCKED, atomic+durable write — tmp `wx`/fsync/rename/dir-fsync mirroring `writeLedger`; enforces the record cap at write time) and `revokeProjectConsent({gsdHome,projectRoot,id})` (LOCKED atomic delete, no-op if absent) — BOTH **THROW** rather than perform an UNLOCKED read-modify-write when the consent-store lock cannot be acquired (finding 3; the lifecycle treats a consent-write failure as non-fatal, and the `trust revoke` CLI catches the throw and emits a clean error). This is the authoritative consent signal the loader recomputes (`bundleContentHash(capDir)`) and checks at load before activating a PROJECT-scope third-party overlay (declarative surfaces AND command dispatch): a forged/cloned in-repo project ledger, OR any post-consent tamper (swapped declarative manifest, edited hook script, empty-integrity local install — all change the recomputed hash), leaves the cap DISCOVERED-BUT-INACTIVE until the user consents on THIS machine to the EXACT bundle (the lifecycle records the consent on a consented project install/upgrade and revokes it on remove; install/lookup/revoke share one canonical `consentProjectRoot` root key). GLOBAL-scope overlays (under the user's own home) need no record; and when `GSD_HOME` resolves (via realpath, defeating symlink aliasing — finding 1) to a genuine project root the in-repo bundle still requires a record. The consent lock is the SHARED hardened primitive (below), so it never stale-steals a slow-but-live writer (finding 4). See `docs/explanation/capability-trust-model.md` "project-scope trust boundary".
### Capability Lock
Issue #1459 finding 4 shared cross-process lock primitive (`gsd-core/bin/lib/capability-lock.cjs`, generated from `src/capability-lock.cts`). Leaf module (`node:fs`/`node:path`/`node:os`/`node:crypto` + the ledger's bounded `readSmallRegularFile` + `shell-command-projection`'s `execTool` for the rare start-time shell-out). THE single hardened lockfile protocol shared by BOTH `capability-lifecycle` (the `.gsd/capabilities/.lock` mutation lock) and `capability-consent` (the consent-store `.consent.lock`) — extracted so the two locks cannot diverge (mirrors the shared-validator / shared bounded-reader lessons). Exports: `acquireLock(lockPath, opts?)` (O_EXCL create with a JSON `{token,pid,hostname,startTime,ts}` body; steal protocol binds age to the body's own `ts`, never stale-steals a VERIFIED-LIVE same-host holder — pid alive AND recorded start-time matches the pid's current start-time, defeating pid-reuse without ever stealing a live holder — and reclaims only a dead/unverifiable holder via the dead-pid fast path or the hard `LOCK_DEADMAN_MS` deadman; `opts.maxAttempts` raises the bounded retry budget and `opts.waitForFresh` makes a contended fresh/live holder be WAITED FOR rather than failed-fast so genuinely-racing consent writers serialize), `releaseLock(handle)` (token + inode owner-safe — never deletes a successor's lock), `getProcessStartTime`, and the `_setLockProbes`/`_resetLockProbes` test seams. Carries the #1462 lifecycle-lock invariants (process-start-time liveness, TOCTOU-safe pre-rename identity recheck, bounded iterative loop).
### Capability Trust Gate
ADR-1244 Phase 4 (D5) PURE policy module (`gsd-core/bin/lib/capability-trust.cjs`). Computes *what* a capability would do and *whether* policy permits it; performs no mutation and no I/O beyond existence-checking declared artifacts. Exports: `discloseExecutableSurfaces(manifest, stagedDir?)` (enumerates the three executable surfaces — `hooks`, command modules, `mcpServers` — and flags `hasExecutable`); `evaluateInstallTrust(args)` (composes source policy + reserved-namespace + engines gate + disclosure into `{ allowed, requiresConsent, disclosure, engines, blockReasons }`); `evaluateSourceAllowed(parsed, strictKnownRegistries)` enforcing `capabilities.strict_known_registries` (unset/null → permissive-with-consent; `[]` → block all external; non-empty → host-based allowlist, never substring); `checkEngines(manifest, hostVersion)` (engines.gsd hard gate via `semverSatisfies` + `compatVersions` graceful-downgrade picking the newest working version); `executableSetChanged(old, new)` (auto-update re-consent trigger); `checkReservedNamespace` (`gsd-`/`gsd-core-`/`anthropic-`). The MCP disclosure also captures each server's `env` (string→string, filtered) and `cwd` (#1459) — `disclosureSignature` folds them in as STABLE SORTED JSON so any env/cwd add/change forces re-consent while a key reorder does not; `signatureForManifest(manifest, stagedDir?)` is the single source of truth for that signature (consumed by the loader's consent check and the lifecycle's consent binding). #1459 finding 5: each MCP surface also carries `rawConfig` — the FULL declared server config the writer persists (`{...config}`), prototype-pollution-cleaned — folded into the signature as STABLE SORTED JSON so a change to ANY persisted field (not just the explicit whitelist — a future `envFile`/`workingDir`/launch option) forces re-consent, while a pure key reorder does not; the human summary stays readable via the key fields only. The barrier is consent + integrity + reversibility, NOT a sandbox — see `docs/explanation/capability-trust-model.md`.
### Capability Lifecycle
ADR-1244 Phase 4 (D5+D6) orchestration seam (`gsd-core/bin/lib/capability-lifecycle.cjs`) composing the source resolver, ledger, and trust gate into the mutating operations. Exports: `installCapability` (pre-fetch source gate → resolve copy-only with `promote:false` → trust verdict → promote + apply marker-stamped shared edits → **ledger commit**; nothing written on block/abort), `upgradeCapability` (atomic stage-then-swap: old set aside, new swapped in, shared edits re-derived, **ledger committed**, backup dropped; re-prompts when the executable set changed), `removeCapability` (strip only `_gsdCapability`-marked shared-config entries — user hand-edits preserved — delete exactly the ledger-recorded files, then drop the entry; `CAPABILITY_DATA` preserved unless `removeData`), `reconcileCapabilities` (crash recovery driven by the ledger's `_pending {kind,backupName,sharedFiles}` INTENT — not a version comparison: roll an uncommitted upgrade back by restoring the backup, an uncommitted fresh install away entirely, and re-sync shared config from the winning bundle, guaranteeing no half-state), plus `applyCapabilitySharedEdits`/`stripCapabilitySharedEdits` (marker-isolated JSON edits, prototype-pollution-guarded). All four mutating ops + reconcile take a cross-process lock (`.gsd/capabilities/.lock`, atomic stale-steal) so a concurrent reconcile can't clear a live intent. Capability code never executes during any operation. The source resolver's `promote:false`/`skipEnginesGate` options are the seams that let this module own the swap/commit ordering and the engines gate (with `compatVersions` downgrade hint).
### Capability Command Dispatch
ADR-1244 Phase 5 (D7) registry-driven dispatch of capability command families. First-party families (`graphify`/`intel`/`audit`, shipped in `bin/lib/`) dispatch via `dispatchCapabilityCommand` (`gsd-core/bin/gsd-tools.cjs`) against the FROZEN `capability-registry.cjs` `commandFamilies` (confined to `bin/lib/`) — unchanged. Third-party (installed overlay) families dispatch via `dispatchOverlayCapabilityCommand`: after the first-party path returns false, it calls `loadRegistry({ includeInstalled, cwd })` and dispatches a family iff its `capId` is in `_overlay.commandRoots` — which `capability-loader.cjs` populates ONLY for accepted overlay capabilities that declare `commands` AND pass the loader's activation gate (a **committed** ledger entry, present and non-`_pending`, PLUS — for PROJECT scope — a matching user consent record in the Capability Consent Store; GLOBAL scope needs no consent record). A bundle dropped on disk with no install (no ledger entry) or no on-this-machine consent is NOT command-dispatchable. The router module is `require()`'d FROM the capability's install root via `defaultRequireFromInstallRoot` (bare-`.cjs` basename + `realpath` containment, rejecting `..` traversal and symlink escape); same own-property/function/sync-only guards as the first-party path. Wired into the `runCommand` default arm before "Unknown command". A repo-planted project ledger no longer activates anything on its own (#1459) — see `docs/explanation/capability-trust-model.md` "project-scope trust boundary".
### Loop Extension Point
A named, stable site on a host loop step (per-step `pre`/`post` plus per-wave in Execute; 12 total) where Capabilities register hooks. Three hook kinds: `step` (runs as its own sequenced unit), `contribution` (injects into the core step's prompt/context), and `gate` (checks and optionally blocks via a declared `blocking` flag). Each hook declares the artifacts it produces and consumes; hook order is derived by topological sort of that produces/consumes graph (capability-id tiebreak), which also defines data flow — file-artifact based, surviving `/clear` and fresh executor contexts. Hooks are surfaced by runtime resolution with concrete projection: the workflow calls a query that resolves the active hooks and returns fully-rendered, ordered markdown for the executor. Failure is default-resilient — a non-gate hook that errors is skipped with a warning; a hook may opt into `onError: halt`. Part of the Capability system. ADR-857 phase 3c ships the registry-consuming query layer: `gsd-core/bin/lib/loop-resolver.cjs` exposes `resolveLoopHooks({ point, registry, config })` (pure, no I/O), `renderLoopHooks(resolved)` (pure markdown renderer), and `cmdLoopRenderHooks(cwd, point, raw, opts)` (I/O entry point); activated via `gsd-tools loop render-hooks <point>` which emits `{ point, activeHooks[], rendered }`. Activation is driven by `when` (dotted config key resolved against `loadConfig`), with inline literal `__proto__`/`constructor`/`prototype` prototype-pollution guard. The first phase-6 cutovers wiring workflows to this query have landed — ui-phase at `plan:pre` and ui-review at `verify:post` (in `plan-phase.md`/`autonomous.md`); further per-feature cutovers are ongoing.
### Capability State Resolver
ADR-857 phase 4b/6 unified resolver that composes the three toggle systems (install profile, runtime surface, config activation) into one per-capability view consumed by workflow hook rendering. Source of truth: `gsd-core/bin/lib/capability-state.cjs` (generated from `src/capability-state.cts`). Interface: `resolveCapabilityState({ registry, installedSkills, surfacedSkills, config, cwd? }) → { capabilities: CapabilityStateEntry[] }` (pure, no I/O); `resolveCapabilityRuntimeState(cwd, runtimeConfigDir)` (I/O resolver shared by workflow dispatch and diagnostics — returns `{ runtimeConfigDir, warnings, capabilities }` only; `registry` and `config` are NOT returned — callers that need them import `capability-registry.cjs` and call `loadConfig(cwd)` directly); `cmdCapabilityState(cwd, runtimeConfigDir, raw, opts)` (I/O output entry point); `isCapabilityActive(capId, cwd): boolean` (convenience predicate — calls `resolveCapabilityRuntimeState`, finds the entry, returns `entry.active`; `false` when capability not found). CLI surface: `gsd-tools capability state [--config-dir <path>]` — emits `{ runtimeConfigDir, capabilities[] }`. Per-capability output: `{ id, tier, skills[], installed, surfaced, enabled, active, hooks[] }` where `installed` = every owned skill ∈ installedSkills (or `installedSkills==='*'`; vacuously true for empty-skills caps), `surfaced` = every owned skill ∈ surfacedSkills (vacuously true for empty-skills caps), `enabled = installed && surfaced` (unchanged — install+surface toggle only), `active = enabled && configActivation` (tri-state deepening: configActivation resolves the capability's `activationKey` via `_resolveActivationValue`; absent `activationKey` → configActivation=true, so `active===enabled` for ungated capabilities), and `hooks` = `[{ point, kind: 'step'|'gate'|'contribution', when, configured, active }]` derived from the cap's `steps`, `gates`, `contributions` arrays (`configured` resolves `when`; `active = enabled && configured`). Capabilities sorted by `id` for determinism. Defensive: malformed registry → `{ capabilities: [] }`, never throws; inline literal `__proto__`/`constructor`/`prototype` prototype-pollution guard on capability id keys.
### Capability State Writer
The write-side mirror of the Capability State Resolver. Takes a desired capability state — per-capability `enabled` plus per-hook `gates` — and projects it onto the substrates: `enabled` drives the runtime surface (`.gsd-surface.json`) as the capability on/off switch; `gates` drive the federated config keys (`config.json` `workflow.*`) for hook-level granularity; the install profile (`.gsd-profile`) is a read-only floor it never writes. Writes the surface once and config once (atomic per substrate), then re-runs the resolver and reports divergence (assert-and-report) — so 'off means off' holds as a write-time invariant rather than by caller discipline. Source of truth: `src/capability-writer.cts`; the surface and config writers become its internal adapters.
### Capability Command Family [Planned — mechanism built, unconsumed]
ADR-959 (phase 4d) — a CLI command family (a top-level `gsd-tools` command and its subcommands) owned by a Capability via a new optional `commands: [{ family, module, router }]` field on the `feature` role. The Capability declares the `family` name, a first-party in-tree `module` (under `gsd-core/bin/lib/`), and the exported `router` — a standard `route*Command({ args, cwd, raw, error })` function identical in shape to the 12 existing host routers (so it routes through the stateless CommandRoutingHub via `routeCjsCommandFamily`, owning its own subcommand list and arg parsing). The registry materializes a `commandFamilies` index (`family → { capId, module, router }`); the formerly-dead `_dispatchNonFamily` shim is replaced by a real `dispatchCapabilityCommand` (exported from `gsd-core/bin/gsd-tools.cjs`) consulted in `runCommand`'s **`default` case** — an unmigrated command hits its hardcoded `case`; a migrated command's `case` is removed so it reaches `default` → registry → router, making collision structurally impossible. The registry *discovers* a router (it does not rebuild a handler table). First-party only; third-party command loading deferred. **Mechanism built (4d-impl-1):** `commands` schema + validator + single-family-ownership cross-check in `gen-capability-registry.cjs`; `commandFamilies` index emitted in the generated `capability-registry.cjs` (currently `{}` — no capability declares commands yet); `dispatchCapabilityCommand` wired into `runCommand`'s `default` case (behavior-preserving today). **Pilot complete (4d-impl-2):** `graphify` cut over as the first real capability command family — `capabilities/graphify/capability.json` bundles the command (`family: graphify`, `module: graphify-command-router.cjs`, `router: routeGraphifyCommand`), skill (`graphify`), config gate (`graphify.enabled`), and `tier: full`; the `case 'graphify':` arm removed from `gsd-tools.cjs`; dispatch flows `default → dispatchCapabilityCommand → commandFamilies.graphify → graphify-command-router.cjs → routeGraphifyCommand`; behavior proven equivalent (all subcommands: build, query, status, diff, build snapshot, unknown subcommand error, usage error, disabled gate). Template for phase-6 per-feature cutovers. **Audit cutover (4d-impl-3):** `audit-uat` and `audit-open` cut over as the second capability command family pair — `capabilities/audit/capability.json` declares two commands (`family: audit-uat`, `module: audit-command-router.cjs`, `router: routeAuditUat`) and (`family: audit-open`, `module: audit-command-router.cjs`, `router: routeAuditOpen`); the `case 'audit-uat':` and `case 'audit-open':` arms removed from `gsd-tools.cjs`; `commandFamilies` now holds `audit-uat`, `audit-open`, and `graphify`; dispatch flows `default → dispatchCapabilityCommand → commandFamilies["audit-uat"|"audit-open"] → audit-command-router.cjs → routeAuditUat|routeAuditOpen`; behavior equivalence proven by existing regression tests (bug-2659, bug-2911, uat.test.cjs) plus new cutover tests. Confirms hyphenated family names pass registry validator (no format restriction beyond non-empty + non-reserved). **Intel cutover (4d-impl-4, last first-party cutover):** `intel` cut over — `capabilities/intel/capability.json` declares the command (`family: intel`, `module: intel-command-router.cjs`, `router: routeIntelCommand`) and the existing config gate (`intel.enabled`, default false); the `case 'intel':` arm removed from `gsd-tools.cjs`; `commandFamilies` now holds `intel`, `audit-uat`, `audit-open`, and `graphify`; dispatch flows `default → dispatchCapabilityCommand → commandFamilies.intel → intel-command-router.cjs → routeIntelCommand`; all 9 subcommands (query, status, update, diff, snapshot, patch-meta, validate, extract-exports, api-surface) and both usage-error paths preserved; non-raw `timeAgo` transform on `status.files[*].updated_at` preserved exactly. `intel.enabled` is Capability-owned config after ADR-857 phase 6. Completes the initial 4d capability command cutover batch.
### Runtime Capability [Planned]
A `role: runtime` variant of a Capability (a Capability carries `role: feature | runtime`) that projects GSD's produced artifacts (skills/agents/hooks/commands) onto one host CLI's conventions — config-surface format, artifact-layout kinds, command template, hooks manifest, sandbox tier. It is a declarative descriptor over a fixed first-party primitive vocabulary (not a code adapter); install composes active Feature Capabilities × the chosen Runtime Capability at the InstallPlan seam (ADR-0058). First-party runtimes are authored through the same descriptor a third party would write (dogfooding the interface); tier-1 (Claude Code, Codex, Antigravity) is fully tested, the other existing runtimes ship lower-tier, none dropped. Third-party runtime loading is deferred to a purely additive external loader + trust gate. Note: "third-party" here is the authorship/distribution axis (who wrote/ships it), distinct from the integration-shape axis (in-host vs Connected Capability).
### Connected Capability [Planned — deferred design]
A Capability whose integration shape brings its own external process, service, or persistent state — for example an MCP server plus a backing database — rather than running entirely within the host's process and trust boundary as declarative artifacts and in-tree first-party code referenced by closed name. Orthogonal to authorship: a Connected Capability may be first-party (e.g. MemPalace, issue #956) or third-party. Contrast with a plain Capability (declarative artifacts + in-host-trust code) and a Runtime Capability (closed-vocabulary projection descriptor), both of which run within host trust. The Connected Capability contract — external-process/MCP-server/backend-provider contributions plus a trust and load gate — is deferred design (ADR-857 §7); vehicle issue #956. It is NOT expressed by the current capability schema.
`RULESET.CAPABILITY.off-means-off=the host derives shared outputs from the ACTIVE hook set (via loop.render-hooks); a hook may ADD a labeled block or be COUNTED into a host-computed aggregate (e.g. a score denominator), but NEVER mutates host source — so a disabled capability yields the base output by construction, not by authoring discipline. Ratify in ADR-894; proven by spike #1018.`
`RULESET.CAPABILITY.cutover-self-gating=a phase-6 per-feature cutover moves the host's phase-context detection + mode/flag logic INTO the skill (self-gating, per ADR-894); the loop hook is intentionally COARSE — "invoke skill X at point Y when config Z" — and carries no detection/mode. WORKED EXAMPLE: plan-phase.md §5.6 UI gate (frontend-detection via ui-safety-gate.cjs + --auto/manual branch + --skip-ui bypass) must move into gsd-ui-phase before its plan:pre hook can replace the inline call without behavior loss. Spike #1018 finding.`
`RULESET.CAPABILITY.step-additive-gate-blocks=a `step` hook is purely additive (invoke skill + produce artifacts, NEVER halts the host); host-blocking preconditions are `gate`s (blocking:true, onError:halt); runtime/mode context (auto/chain vs manual) self-gates IN THE SKILL, not via `when` (config-only). §5.6 = plan:pre step (ui-phase; skill self-gates on frontend+pipeline, auto-fires only in pipelines) + a NEW plan:pre gate (frontend-and-no-UI-SPEC → halt, when:workflow.ui_safety_gate); the loop.render-hooks dispatch template handles steps AND gates. Resolves #1022.`
`RULESET.CAPABILITY.precedence-engine-single-owner=the config-key four-level precedence walk (loadConfig result → workstream config.json → root config.json → registry.configSchema default → absent) is owned solely by src/capability-activation.cts: raw-value primitive resolveConfigKey(dotKey, {config,cwd,registry}) and boolean wrapper _resolveActivationValue(dotKey,config,cwd,registry); loop-resolver.cts imports the engine (no duplicate); resolveConfigValues in loop-resolver.cts delegates to resolveConfigKey; resolveCapabilityRuntimeState does NOT return registry/config — callers import capability-registry.cjs and call loadConfig(cwd) directly.`
### Teams Status Module
Pure read-only detector for claude-code's experimental agent-teams feature (issue #1355). Stops gsd-core hanging silently when run under `CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS`. Source of truth: `src/teams-status.cts` → `gsd-core/bin/lib/teams-status.cjs`. Exports: `resolveTeamsStatus({ runtime, env }) → TeamsStatus` (pure, env injected, no process.env/disk inside — hermetic for tests) and `cmdTeamsStatus(cwd, { active? })` (I/O entry point; reuses `resolveRuntime` from `runtime-slash.cjs` for canonical `GSD_RUNTIME` → `config.runtime` → `'claude'` precedence). `TeamsStatus` shape: `{ active: boolean, runtime: string, env_present: boolean, source: 'on: env' | 'off: flag absent' | 'off: non-claude' }`. `active` is true only when the flag is strictly truthy (`"1"` or `"true"`, case-insensitive) AND the runtime is `"claude"`. CLI surface: `gsd-tools query teams-status [--active]` (default: JSON; `--active`: exit 0/1 boolean). Used only by a non-fatal `--active` check warning in `plan-phase.md` init block — does NOT block execution, does NOT activate capabilities, does NOT change behavior on any non-claude runtime.
### Wing
A MemPalace organizational unit corresponding to one project or repository. GSD derives the wing name from `project_code` or the project directory when `mempalace.wing` is unset. A wing contains Rooms. Cross-project Tunnels connect rooms across wings. MemPalace vocabulary — see Connected Capability, MemPalace memory capability (issue #956).
### Room
A named bucket inside a Wing that groups drawers by semantic kind. GSD maps its phase artifacts to five fixed rooms: `decisions` (CONTEXT.md), `planning` (PLAN.md), `milestones` (SUMMARY.md/UAT.md excerpts), `problems` (confirmed bug→fix pairs), and `learnings` (extract-learnings output). MemPalace vocabulary — see Wing.
### Drawer
A verbatim-content unit stored inside a Room. GSD files phase artifacts as drawers using `mempalace_add_drawer`; duplicate-check via `mempalace_check_duplicate` makes capture idempotent. GSD stores verbatim text (not AAAK summaries) to preserve recall fidelity. MemPalace vocabulary — see Room.
### Tunnel
A cross-Wing knowledge connection created by `mempalace_create_tunnel`. GSD proposes tunnels at `ship:post` when `mempalace.cross_project_tunnels: true`, linking rooms in the current wing to semantically related rooms in other project wings. MemPalace vocabulary — see Wing.
### Diary
A per-agent narrative entry written by `mempalace_diary_write`. GSD's `gsd-mempalace-curator` writes a diary entry at `ship:post` when `mempalace.diary_journal: true`, recording a session summary scoped to the project and agent role. MemPalace vocabulary — see Connected Capability.
### memory_mode
The `mempalace.memory_mode` config key controlling how tightly MemPalace couples to GSD's native memory. Three declared values: `augment` (default — **implemented**; palace is an additional write-mostly recall layer; lowest coupling), `kg_backend` (**declared; routing seam not yet implemented** — intended to route graphify KG queries through MemPalace's temporal graph; selecting today behaves as `augment`), `replace` (**declared; not yet functional** — intended to make the palace the durable store; selecting today behaves as `augment`). Only `augment` has effect in the current release; `kg_backend` and `replace` are forward-declared for a future release. Read at hook-render time; switching is a config change, not a reinstall. See MemPalace Settings in `docs/CONFIGURATION.md`.
### Runtime Hooks Surface Module
Standalone hook-surface writer module extracted from `bin/install.js` as ADR-857 phase 5f-1 (behavior-preserving relocation, no logic change). Owns: Cline rules-body/agents-md/pre-tool-use hook generation (`buildClineRulesBody`, `buildClineAgentsMdBody`, `buildClinePreToolUseHook`, `mergeGsdAgentsMd`, `writeClineArtifacts`); Cursor `hooks.json` lifecycle (`buildCursorHookEntry`, `isManagedCursorHookEntry`, `reconcileCursorHooksJson`, `writeCursorHooksJson`, `removeCursorHooksJson`); Copilot session-hook config (`buildCopilotHookConfig`, `writeCopilotHookConfig`); Codex hook-block and event management (`buildCodexHookBlock`, `rewriteLegacyCodexHookBlock`, `reconcileCodexHooksJsonEvent`, `reconcileCodexHooksJsonSessionStart`, `ensureCodexHooksJsonSessionStart`, `ensureCodexHooksJsonEvent`, `removeCodexHooksJsonEvent`, `removeCodexHooksJsonSessionStart`, `buildCodexHookWindowsShimIR`); and shared hook command helpers (`buildHookCommand`, `rewriteLegacyManagedNodeHookCommands`, `normalizeNodePath`, `resolveNodeRunner`). `bin/install.js` delegates to this module via thin wrappers and re-exports its functions unchanged so existing tests require no modification. Source: `src/runtime-hooks-surface.cts`. Built output: `gsd-core/bin/lib/runtime-hooks-surface.cjs`.
### Runtime Config Adapter Registry
Module owning the explicit per-runtime config-mutation dispatch table for the installer. `resolveRuntimeConfigIntent(runtime)` projects a typed config intent — `installSurface` (`settings-json` | `codex-toml` | `copilot-instructions` | `cline-rules` | `cursor-hooks-json` | `profile-marker-only`), `writesSharedSettings` (the `finishInstall` shared-settings write gate), and `finishPermissionWriter` (`opencode` | `kilo` | none) — that `bin/install.js` dispatches on instead of inline `runtime === '...'` branching. Owns adapter selection only: it performs no filesystem IO and does not execute config mutations (the install/finishInstall handlers and the per-runtime writers do that). Unknown runtimes fail loudly with a `TypeError`, guarded by an `Object.hasOwn` own-property check so prototype-chain keys (`__proto__`, `constructor`) also throw. Also exports `resolveInstallPlan(runtime)` — the ADR-58 `InstallPlan` capstone — which collects the install-level descriptor axes (`installSurface`, `writesSharedSettings`, `finishPermissionWriter`, `hookEvents`, `extendedHookEvents`, `hooksSurface`, `sandboxTier`) into one typed `InstallPlan` value consumed by `install()` and `finishInstall()` in `bin/install.js`. `sandboxTier` (`none` | `codex-agent-sandbox`) gates per-agent `sandbox_mode` emission in the codex TOML path and fails loud on a missing/invalid value (#1151). The spatial axes (`configHome`, `artifactLayout`, `commandStyle`) remain behind their self-resolving adapter modules and are not part of the plan; they are the execution adapters. Realizes both the adapter-selection and plan-collection halves of the Runtime Install Policy Module boundary. Source: `gsd-core/bin/lib/runtime-config-adapter-registry.cjs`. See ADR-58, #60.
### Claude Code Plugin Manifest Module
Module owning the projection of gsd-core's artifact surfaces (`commands`, `agents`, hooks) onto the Claude Code plugin contract (`.claude-plugin/plugin.json` + `hooks/hooks.json`) — the plugin-contract sibling of the Runtime Artifact Layout Module (which projects the same surfaces onto filesystem placements). Defined mapping: `name`=`binName` (drives the `/gsd-core:` command namespace), `repository`/`homepage`=`repoUrl` (Package Identity Module), `version`/`description`/`license` from `package.json` (`version` is required for `claude plugin validate --strict`), `commands`=`./commands/gsd/`, agents via Claude Code's default `agents/` discovery (the explicit string form is schema-rejected), `hooks`=`./hooks/hooks.json`. The hook projection carries ONLY the always-on subset of the Installer Module's Claude `settings.json` wiring (check-update, context-monitor, prompt-guard, read-guard, worktree-path-guard, read-injection-scanner) via `${CLAUDE_PLUGIN_ROOT}`; config-gated opt-in hooks are excluded because a static manifest cannot honor per-project config gates, and plugin-shipped agents cannot carry hook frontmatter (so all plugin-path hook wiring lives in hooks.json). `hooks.json` covers all seven Claude Code lifecycle events: SessionStart, PreToolUse, PostToolUse, SubagentStop, Stop, PreCompact (all wired to context-monitor for context-headroom awareness), and FileChanged (matcher: `config.json` → config-reload, injects `additionalContext` when `.planning/config.json` changes mid-session). Additive — the file-copy path (Runtime Artifact Layout / Install Policy / Installer Modules) is unchanged. Conformance is validated by `claude plugin validate --strict` plus the in-repo drift-guard `tests/issue-766-plugin-manifest.test.cjs`. _Avoid_: "the plugin API", "the plugin file" (when you mean the seam). See ADR-766 and Runtime Artifact Layout Module.
### Gemini Extension Package
The repo-root `gemini-extension.json` + `GEMINI.md` pair that projects gsd-core onto the Gemini CLI extension contract, enabling one-step lifecycle management via `gemini extensions install <git-url>` / `update` / `remove` (and `gemini extensions link <path>` for dev). The Gemini-CLI sibling of the Claude Code Plugin Manifest Module — same additive idea, different runtime package format. Defined mapping: `name`=`binName` (`gsd-core`; lowercase-dashes per Gemini's extension naming rule), `version` tracks `package.json` (Gemini's `gemini extensions update` keys off the manifest `version` field), `description` (required by the manifest schema), `contextFileName`=`GEMINI.md` (the extension's context payload, loaded into every Gemini session). Intentionally minimal: no `mcpServers` (gsd-core ships no MCP server). Slash-command / agent / hook projection into the extension (which would require committing the Gemini-format TOML/agent conversions the Installer Module produces at `--gemini` install time) is deferred — the manual `npx gsd-core --gemini` path remains the way to install the `/gsd:*` commands, and is unchanged (additive, no breaking change). Conformance is guarded by the in-repo drift test `tests/issue-775-gemini-extension.test.cjs` (manifest validity, `version`↔`package.json` parity, `contextFileName` existence, `files[]` publication). _Avoid_: "the Gemini plugin" (Gemini calls them extensions, not plugins). See #775, ADR-766, Claude Code Plugin Manifest Module, and Runtime Artifact Layout Module.
### Knowledge Graph Module
Module owning the graphify integration: tri-state capability gate (`isCapabilityActive('graphify', cwd)` from capability-state.cjs — requires installed AND surfaced AND config-enabled; replaces the former config-only `isGraphifyEnabled` gate, cutover in #1306), disabled response (`disabledResponse`), subprocess helper (`execGraphify`, typed `GRAPHIFY_REASON` enum), presence detection (`checkGraphifyInstalled`), version checking (`checkGraphifyVersion`), query surface (`graphifyQuery` — BFS seed-expand + budget trim), status surface (`graphifyStatus` — node/edge counts, mtime staleness, commit-staleness tri-state via `built_at_commit`/`commits_behind`/`commit_stale`), diff surface (`graphifyDiff` — added/removed/changed nodes+edges), build pre-flight (`graphifyBuild`), snapshot management (`writeSnapshot`). Config leg reads `.planning/config.json:graphify.enabled`; all three legs (install, surface, config) must be active; writes to `.planning/graphs/`. Auto-update hook (`hooks/gsd-graphify-update.sh`) triggers a detached background rebuild after HEAD-advancing git operations on the default branch when `graphify.auto_update=true`. Status file `.planning/graphs/.last-build-status.json` carries `{ ts, status, exit_code, duration_ms, head_at_build, graphify_version }`. Graph IR uses `nodes[]`, `edges[]` (or `links[]` for graphify ≥0.7 compat), `hyperedges[]`, `built_at_commit`. `commit_stale` is tri-state: `false` (known fresh), `true` (stale), `null` (unknown — no git or pre-v0.7 graph). Source: `gsd-core/bin/lib/graphify.cjs`. Skill: `commands/gsd/graphify.md`.
### Intel Module
Module owning the code-intelligence store: tri-state capability gate (`isCapabilityActive('intel', cwd)` from capability-state.cjs — honours installed+surfaced+config-enabled; replaces the former config-only `isIntelEnabled` gate, cutover in #1307; intel has `skills:[]` so installed/surfaced are vacuously true and the effective gate is `intel.enabled` in config), disabled response, query surface (`intelQuery` — full-text search across all intel JSON files), status surface (`intelStatus` — per-file freshness, 24-hour staleness threshold), diff surface (`intelDiff` — added/changed/removed files vs last-refresh snapshot), snapshot management (`saveRefreshSnapshot`/`intelSnapshot`), validation (`intelValidate` — existence, JSON validity, _meta.updated_at recency), api-surface render (`intelApiSurface` — generates `.planning/intel/API-SURFACE.md` from `api-map.json`), plus ungated utilities (`intelPatchMeta` — patches `_meta.updated_at` in any JSON file; `intelExtractExports` — extracts CJS/ESM exports from any JS file). Loop hook rendering gates on `state.active` (not `state.enabled`) so the `activationKey` config gate is honoured even without a per-hook `when` guard (Phase 4 tri-state alignment, #1307). Source: `gsd-core/bin/lib/intel.cjs` (generated from `src/intel.cts`). Router: `gsd-core/bin/lib/intel-command-router.cjs`. See Capability Command Family Module (ADR-959 4d-impl-4) and Loop Extension Point.
### Research Module
The GSD-RESEARCH capability behind an L2-hybrid seam: code owns cache + provider policy + package legitimacy; MCP owns the actual fetch. Reachable via `gsd-tools query research-plan|research-store|package-legitimacy`. Source: `src/research-{store,provider}.cts` + `src/package-legitimacy.cts` (generated to `gsd-core/bin/lib/*.cjs` per ADR-457). Replaces the prose provider-waterfall duplicated across the researcher agents and the pip-install `slopcheck` bolt-on.
- `GSD-RESEARCH.MODULE.research-store=content-addressed cache; key=sha256(ecosystem+library+version+query+kind); getResearch->{hit,stale} never throws (mirrors graphify staleness); ttlForSource curated HIGH 30d|MED 7d|web LOW 1d; tiers: curated-doc kinds -> ~/.gsd/research-cache (cross-project), web/synthesis -> project .planning/research/.cache`
- `GSD-RESEARCH.MODULE.research-provider=single source of truth PROVIDER_WATERFALL (docs Context7->Ref->Jina->websearch; web Exa->Tavily->Perplexity->Brave->websearch; scrape Firecrawl->Jina); planResearch returns cache-hits+fetch-plan; classifyConfidence stamps HIGH|MEDIUM|LOW by provider AUTHORITY + verification EVIDENCE (HIGH requires code-computed ground-truth corroboration e.g. legitimacyVerdict OK; provider authority alone caps at MEDIUM; SLOP caps at LOW); Firecrawl is scrape-only (not in docs/web discovery)`
- `GSD-RESEARCH.MODULE.package-legitimacy=registry-API verdicts (npm/PyPI/crates.io injectable adapters) computed from thresholds {minAgeDays:30,minWeeklyDownloads:1000,requireRepo:true}; verdict OK|SUS|SLOP per package; slopcheck=optional adapter that can only escalate, never the install-or-degrade gate`
- `GSD-RESEARCH.INTEGRATION.L2-hybrid=code owns cache+legitimacy+confidence+provider-pick (gsd-tools query research-plan/research-store/package-legitimacy); MCP owns the fetch; agent returns RESEARCH.md path, never raw fetches`
- `GSD-RESEARCH.PROVIDER.availability=config flags brave_search/exa_search/firecrawl/tavily_search/ref_search/perplexity/jina (env <X>_API_KEY or ~/.gsd/<x>_api_key); context7/jina/websearch always available; planResearch falls through waterfall to websearch terminal`
- `GSD-RESEARCH.CONTEXT-DISCIPLINE=less-context levers: subagent isolation + compact provider output + fetches-to-disk + cache-returns-digest; API clear_tool_uses/memory tool are the conceptual model, not a Claude Code harness knob`
- `DEFECT.RESEARCH-PROVIDER-PROSE-DRIFT=provider waterfall duplicated across N researcher agent .md files drifts independently (META.RULE.brief-no-paraphrase); fix-forward=research-provider.cjs single source of truth + generated agents (#657)`
### UAT-Passed Predicate
Runtime-neutral predicate evaluating `*-UAT.md` / `*-VERIFICATION.md` result fields with markdown-aware parsing that ignores false-positive contexts (frontmatter body, fenced code, HTML comments, blockquotes). Returns `passed: true` only when all required checks pass; supports `--require-verification` to demand at least one VERIFICATION.md file alongside UAT results. Output envelope: `{ passed, uat_files[], verification_files[], checks[], blockers[], policy }`. Source: `gsd-core/bin/lib/uat-predicate.cjs` (generated from `src/uat-predicate.cts`). Wired via `phase uat-passed` alias → `phase-command-router` → `cmdPhaseUatPassed`.
### Coverage Metadata Module
Deterministic classifier for the per-deliverable coverage RTM on SUMMARY.md (#1602). Parses the optional `coverage:` frontmatter block (a list-of-maps-with-nested-list-of-maps that `extractFrontmatter` cannot represent — so a dedicated indentation parser, sibling of `parseMustHavesBlock`), validates each entry's schema, and classifies each into `auto_passed` (deterministically covered) vs `present` (human UAT required). Output envelope: `{ mode, summary_file, total, all_auto_covered, auto_passed[], present[], errors[] }` with frozen `MODE`/`PRESENT_REASON`/`ERROR_CODE` enums. Auto-pass requires the narrow proven case (strict-boolean `human_judgment:false` AND non-empty all-`pass` verification AND zero errors); everything else, including a malformed entry, routes to `present` (fail-safe — never drops a deliverable, never false-auto-passes). `mode:legacy` (absent block) ⇒ caller falls back to prose `## Accomplishments` extraction, byte-identical for un-migrated phases. Source: `gsd-core/bin/lib/coverage.cjs` (generated from `src/coverage.cts`). Wired via `uat classify-coverage --summary <f>` → `cmdClassify`; authored by `execute-plan` create_summary, consumed by `verify-work` extract_tests. See `RULESET.WORKFLOW.COVERAGE-METADATA`.
### Probe Core Module
Generic spec-phase probe resolution model — the shared seam underlying spec-completeness probes (ADR-550 Decision 7). Owns the `status × verification` model (`status: resolved | dismissed | unresolved` × a per-probe `verification` tier), structural validation (`validateResolution`, `validateRequirement` — fail-closed: `verification` must be null unless status is `resolved`, and an out-of-enum status, a `dismissed`-without-`reason`, or an `unresolved` carrying a `resolution`/`reason`/tier payload all throw rather than silently miscount), the `analyzeCoverage(items, resolutions?, validators)` merge/rollup/orphan-reject pipeline, the `byVerification` per-tier rollup, and the `runProbeCli` I/O scaffold (parse → validate → analyze → emit, structurally guarding the report shape before write — a malformed report fails closed with stderr + exit 2 instead of stringifying as green). Adapter-agnostic: consumed by the Edge Probe Module today and the Prohibition Probe Module (#644) next. Exports (generic surface): `VALID_STATUS`, `validateResolution`, `validateRequirement`, `analyzeCoverage`, `runProbeCli` — the prohibition adapter exports that also ship from this module (`projectProhibitions`, `PROHIBITION_VALIDATORS`, `validateProhibitionResolution`, `dispositionForProhibition`) are documented under the Prohibition Probe Module's own locked-surface line. Source of truth: `gsd-core/bin/lib/probe-core.cjs` (generated from `src/probe-core.cts`, gitignored per ADR-457). Tests: `tests/probe-core.test.cjs`. See ADR-550 and Edge Probe Module. Under ADR-857 (phase-6 boundary, settled 2026-06-12) this seam is classified **core verification substrate** on the *contract* side: its deterministic validators are the verifier↔predicate contract's CI-testable surface (ADR-550 Decision 5) — core and non-toggleable, never an off-by-default Feature Capability. (The recall-gapped *generator* is the probe adapters that propose predicates, not this resolution engine — see Edge Probe Module and Verification substrate (predicate boundary).)
### Edge Probe Module
First adapter of the Probe Core Module (ADR-550 Decision 7): the spec-phase edge-completeness probe wired into spec-phase Step 5.5. Owns shape classification (`classifyShape`), the applicable-category relevance filter (`applicableCategories` over the 8-category edge `TAXONOMY`), edge proposal (`proposeEdges`), and the `{explicit, backstop}` verification validators; delegates merge/rollup/CLI to `probe-core`. Fail-closed input contract: an edge requirement with missing/empty `text` and no `shapes` override is rejected (a `{ id }`-only requirement no longer classifies to zero edges and silently drops), while the legitimate `shapes: []` opt-out is preserved. Downstream, the `plan-phase` planner lifts every `covered`/`backstop` edge from the SPEC `## Edge Coverage` section into `must_haves.truths`. Exports (locked surface): `classifyShape`, `applicableCategories`, `proposeEdges`, `analyzeCoverage`, `validateResolution`, `validateRequirement`, plus the constants `TAXONOMY` (the **closed** 8 edge categories), `UNCLASSIFIED_CATEGORY` (the `unclassified` review-manually sentinel for zero-cue prose, #1110 — deliberately **not** a 9th taxonomy entry: it stays out of `TAXONOMY` but is present in `EDGE_VALIDATORS.categories`), `VALID_SHAPES`, `SHAPE_CUES`, and `EDGE_VALIDATORS` (the `{explicit, backstop}` validators bundle injected into `probe-core`'s generic engine; its `categories` = the `TAXONOMY` ids plus `UNCLASSIFIED_CATEGORY`). Source of truth: `gsd-core/bin/lib/edge-probe.cjs` (generated from `src/edge-probe.cts`, gitignored per ADR-457). Tests: `tests/edge-probe.test.cjs`, `tests/edge-probe-spec-phase-contract.test.cjs`, `tests/edge-probe-planner-contract.test.cjs`. See ADR-550 and Probe Core Module. Per ADR-857's phase-6 boundary (2026-06-12) the predicates this module generates are **core verification substrate** (they set the verifier's reach), so it is wired onto the core predicate rail as a core-default module rather than migrated to an off-by-default `capabilities/edge-probe/` Feature Capability.
### Verification substrate (predicate boundary)
The ADR-857 classification (settled 2026-06-12, prompted by @davesienkowski's boundary analysis on #857) that predicate-generation — the must-NOT-have / edge predicates that set the verifier's reach — is **core**, not an off-by-default Feature Capability. Load-bearing premise: *verifier reach = spec reach* (the verifier can only catch what the spec concretely names). Decomposes into: the **verifier↔predicate contract** (the verifier always expects predicates and grades **exogenously** against them — core, non-toggleable, a stability contract alongside the Loop Extension Point names), and the **generator** (the probe *adapters* that propose predicates — edge-probe's `classifyShape`/`proposeEdges`, the prohibition probe's adversarial LLM-propose — core-default but independently versionable, kept their own module because of a measured recall gap; `probe-core`'s deterministic validators sit on the contract side, not the generator side). Altitude rule distinguishing it from `gate` hooks: a gate runs *against* the spec (hook); predicate-generation defines the spec's *reach* (core). The decision-#6 `produces`/`consumes` artifact flow is the internal rail from generation to the core verifier. See ADR-857 *Verification substrate vs. plug-in tier (the predicate boundary)* and the ADR-550 cross-reference.
### Probe Family
The set of spec-phase completeness probes that share the Probe Core Module seam (ADR-550 Decision 7): the Edge Probe (Step 5.5, data-shape edges) and the Prohibition Probe (Step 5.6, unwritten *must-NOT* constraints) today, with room for a third nearly-free adapter. A "probe" walks each SPEC requirement, surfaces candidate omissions, and resolves each through the shared `status × verification` model — but each family member owns its own *recall* mechanism: a deterministic closed-taxonomy classifier for edges (shape→category), open-vocabulary adversarial LLM prose for prohibitions (recall is model-driven, not a compute adapter — ADR-550 D7b). What is shared is the resolution/validation/rollup engine and the soft-gate lifecycle; what diverges is how candidates are recalled. See Probe Core Module, Edge Probe Module, Prohibition Probe Module.
### Verification Tier
The orthogonal `verification` dimension a resolved probe item carries alongside its `status` (ADR-550 D7a — `status: resolved | dismissed | unresolved` is the shared resolution lifecycle; `verification` is the probe-defined enforcement axis). Each probe defines its own tier vocabulary: the edge probe uses `explicit | backstop`; the prohibition probe uses `test | judgment`. For prohibitions the tier names *how* a must-NOT can be enforced — `test` (a negative test can fail-close on it) vs `judgment` (an irreducible values/safety rule only human/LLM judgment can assess). Verify-phase routes on the tier: `test`-tier items must be provably wired and fail closed when unwired (never a silent green); `judgment`-tier items take the mode-dependent soft-gate (ADR-550 D4 — interactive demands human resolution, autonomous records a non-authoritative LLM-judge verdict + an `unverified-prohibition` flag, never a silent pass and never a hard halt). The rollup exposes `coverage.byVerification: { <tier>: count }` so verify-phase reads the per-tier denominator without re-scanning. See Probe Core Module, Prohibition Probe Module.
### Bespoke vs Canon Prohibition
The ownership seam between the prohibition probe and security/compliance tooling (ADR-550 D6). The probe owns **bespoke** product/values prohibitions — the unwritten must-NOTs specific to this feature's intent (e.g. "the streak reminder must not manipulate the user into returning"). When precision classifies an item as a **canon** security/compliance concern (OWASP / GDPR / fairness / prototype-pollution / path-traversal — the codified, cross-project rule sets), the probe does **not** mint a SPEC prohibition: it emits a one-line breadcrumb (*"possible canon-security concern X — owned by `/gsd:secure-phase` / eslint"*) and stops. Canon checks are **referred, not duplicated** — keeping the surfaced list short (#644's ~2–3-item precision goal) and the secure-phase boundary explicit. See Prohibition Probe Module.
### Prohibition Probe Module
Second adapter of the Probe Core Module (ADR-550 Decision 7): the spec-phase prohibition-completeness probe wired into spec-phase Step 5.6, surfacing the unwritten *must-NOT* constraints (values/safety/ethics) the spec never forbids. Unlike the Edge Probe, recall is **prose-orchestrated, not a compiled engine** (ADR-550 D7b) — a two-stage pass per requirement: Stage 1 an adversarial recall question, Stage 2 a one-pass precision classifier (drop routine engineering, keep genuine prohibitions). The code surface is schema/projection only: `projectProhibitions()` (deterministic SPEC↔`must_haves.prohibitions` projection backing the `DEFECT.GENERATIVE-FIX` parity assertion), the `{test, judgment}` `PROHIBITION_VALIDATORS`, `validateProhibitionResolution`, and `dispositionForProhibition()` (the fail-closed default — an unwired `test`-tier item resolves to `unverified`/flagged, never green). **Deterministic test-tier locate (#1278, ADR-550 D3 addendum):** a resolved `test`-tier prohibition MAY carry an optional flat-scalar `check` descriptor — `check_kind` (`node-test` | `lint-rule`), `check_target`, and `check_rule` (lint-rule only) — that `projectProhibitions` emits into `must_haves.prohibitions` when well-formed, and `descriptorFromProjection()` (the read-back seam in the #1259 enforcement producer, `src/prohibition-enforcement.cts`) reconstructs into a `{kind, target, rule?}` `CheckDescriptor`, so verify-phase locates the wired check with zero LLM/author authoring. **Flat scalars, never a nested `check:{}` object** — so the round-trip rides the *unchanged* shared `parseMustHavesBlock` (the #644 no-parser-rewrite precedent); an absent/partial descriptor falls through to the producer's existing fail-closed locate, and `failFirst` stays caller-attested (machine-proof is #1279). No `proposeProhibitions()` — recall is LLM prose. `plan-phase` lifts every resolved prohibition from the SPEC `## Prohibitions (must-NOT)` section into the `must_haves.prohibitions` sibling block (never `truths`). Exports (locked surface): `projectProhibitions`, `PROHIBITION_VALIDATORS` (the `{test, judgment}` validators bundle injected into `probe-core`'s generic engine), `validateProhibitionResolution`, and `dispositionForProhibition` (the fail-closed disposition) — the prohibition adapter surface, shipped from `probe-core` alongside the generic engine. Source of truth: `gsd-core/bin/lib/probe-core.cjs` (the prohibition exports live in `src/probe-core.cts`, gitignored per ADR-457) + `gsd-core/references/prohibition-probe.md`. Tests: `tests/prohibition-probe.*.test.cjs`. See ADR-550, Probe Core Module, Edge Probe Module, Verification Tier, Bespoke vs Canon Prohibition.
### MVP Mode
Phase-level planning mode that frames work as a vertical slice (UI → API → DB) of one user-visible capability instead of horizontal layers. Resolved at workflow init via the precedence chain: `--mvp` CLI flag → ROADMAP.md `**Mode:** mvp` field → `workflow.mvp_mode` config → false. All-or-nothing per phase (PRD #2826 Q1). Surfaced as `MVP_MODE=true|false` to the planner, executor, verifier, and discovery surfaces (progress, stats, graphify). Canonical parser: `roadmap.cjs` `**Mode:**` field; canonical resolution chain documented in `workflows/plan-phase.md`. Concept index: `references/mvp-concepts.md`.
### User Story
Phase-goal format under MVP Mode: `As a [role], I want to [capability], so that [outcome].` Required regex shape: `/^As a .+, I want to .+, so that .+\.$/`. Used as the framing input by `gsd-planner` (emits as bolded `## Phase Goal` header in PLAN.md) and as the verification target by `gsd-verifier` (the `[outcome]` clause is the goal-backward verification anchor). Authored interactively by `/gsd-mvp-phase`, validated by SPIDR Splitting when too large.
### Walking Skeleton
Phase 1 deliverable under `--mvp` on a new project: the thinnest end-to-end stack proving every layer (framework, DB, routing, deployment) works together. Emitted as `SKELETON.md` capturing the architectural decisions subsequent vertical slices inherit. Gate fires when `phase_number == "01"` AND `prior_summaries == 0` AND `MVP_MODE=true`. Scope intentionally narrow (PRD #2826 Q2) — does not retrofit existing projects.
### Vertical Slice
Single-feature task that moves one user capability from open-to-close (happy path) end-to-end. Contrast with the horizontal layer (all models, then all APIs, then all UI). The MVP Mode planning unit; SPIDR Splitting axes (Spike, Paths, Interfaces, Data, Rules) are the canonical decomposition tools when a slice is too large for one phase.
### Behavior-Adding Task
Predicate over a PLAN.md task: `tdd="true"` frontmatter AND `<behavior>` block names a user-visible outcome AND `<files>` includes at least one non-`*.md` / non-`*.json` / non-`*.test.*` source file. Pure doc/config/test-only tasks are exempt. The MVP+TDD Gate (in `references/execute-mvp-tdd.md`) only halts execution on this predicate; the gsd-executor agent applies all three checks at runtime. Currently a prose-only specification — no shared utility.
### MVP+TDD Gate
Per-task runtime gate in `/gsd-execute-phase` that, when both `MVP_MODE` and `TDD_MODE` are true, refuses to advance a Behavior-Adding Task until a failing-test commit (`test({phase}-{plan})`) exists for it. The `tdd_review_checkpoint` end-of-phase review escalates from advisory to blocking under the same condition. Documented contract: `references/execute-mvp-tdd.md`. Reserved escape hatch `--force-mvp-gate` is documented but not implemented.
### SPIDR Splitting
Five-axis story decomposition discipline (**S**pike, **P**aths, **I**nterfaces, **D**ata, **R**ules) used by `/gsd-mvp-phase` when a User Story is too large for one phase. Full interactive flow per PRD #2826 Q3 (not a lightweight filter). Reference: `gsd-core/references/spidr-splitting.md`.
### Clock seam
An injectable time abstraction accepted as an optional parameter by production code (`{ clock = Date } = {}`). Test code substitutes `node:test` `mock.timers` to control time deterministically without waiting for real OS scheduler events. Canonical pattern established by ADR 456 (`docs/adr/456-test-rigor-architecture.md`).
### Deterministic scheduler
Test-execution model in which all timing and concurrency outcomes are fully controlled by the test (via clock seam, explicit `await` ordering, or synchronous stepping) rather than by the OS thread scheduler. Opposed to real-race tests, which are non-deterministic on loaded CI runners.
### Property-based test
A test that generates many adversarial inputs automatically (via `fast-check`) and asserts that a stated invariant holds for all of them, rather than asserting on a fixed set of hand-chosen examples. Invariant categories used in this codebase: round-trip, monotonicity, boundary containment, idempotency. See `RULESET.TESTS.property-based-testing`.
### Mutation testing / mutation score
Stryker injects small code mutations (e.g., flipping a `>` to `>=`, deleting a `return` statement) and reruns the test suite for each. A mutation is "killed" if at least one test fails; "surviving" if all tests pass despite the mutation. Mutation score = killed / total. Score below 80 % on the changed scope blocks PR merge. See `RULESET.TESTS.mutation-score`.
### ESLint harness
The canonical lint infrastructure adopted in ADR 452 (`docs/adr/452-eslint-lint-harness.md`): ESLint flat config (`eslint.config.mjs`) with `typescript-eslint`, `eslint-plugin-n`, `eslint-plugin-no-only-tests`, and a local AST-rule plugin at `scripts/eslint-rules/`. Replaces the homegrown `scripts/lint-*.cjs` regex scanners. The three custom test-rigor rules (`local/no-source-grep`, `local/no-magic-sleep-in-tests`, `local/no-elapsed-assertion`) initially ship at `warn`; they become `error` after the cleanup sweep tracked at issue #453 merges.
### External-job-waiting half-state
A legal deferred state of an Execute step (`external_job_waiting`): the executor has dispatched a long-running async external job and committed an async-job manifest at `.planning/async-jobs/<job>.json` instead of a SUMMARY.md. Distinct from the synchronous "mid-production-commits" half-state and from an illegal partial-plan state. The core loop's step-completion + safe-resume/pause contract treats a non-terminal manifest as legal and reconciles against it (never re-dispatching the plan, which would duplicate the external job); SUMMARY.md is deferred until the job reaches a terminal state and its `expected_artifacts` are verified. The manifest is a versioned stability contract (`docs/reference/planning-artifacts.md`); core *consumes* it while a default-off scheduler-adapter Capability (#1164) *produces* it at `execute:wave:post` — the contract-is-core / producer-is-capability seam mirrors ADR-857's verification-substrate decision. Status enum is closed and scheduler-agnostic: `submitted`, `running`, `completed-unverified`, `failed`, `cancelled`, `timeout`.

## Shell Command Projection Module (expanded glossary entry, 2026-05-13)
Module owning all OS-facing I/O for the tool: runtime-aware command-text rendering (hook commands, PATH action lines, shim scripts), subprocess dispatch (run-git, run-npm, run-tool, probeTty), and platform file I/O (platformWriteSync, platformReadSync, platformEnsureDir). Single seam for platform-conditional logic — one place to fix any shell or file write regression across Windows, macOS, and Linux. Lives in `gsd-core/bin/lib/shell-command-projection.cjs`. See ADR-0009 (superseded "does not execute" constraint) and ADR-0010 (superseded File Operation Engine).
Invariants:
- Result shape: all run-* return `{ exitCode, stdout, stderr }`; never throw on non-zero exit code.
- Platform policy owned at the seam: `shell: process.platform === 'win32'` lives only in run-npm; probeTty returns `null` on Windows.
- Normalization policy: platformWriteSync owns full `normalizeMd` for `.md`; CRLF-to-LF + trailing newline for all others; callers must NOT pre-call `normalizeMd`.
- `_normalizeMd` is re-implemented inline (not imported from `core.cjs`) to avoid circular dep.
- `atomicWriteFileSync`, `safeReadFile`, `normalizeMd` were in `core.cjs` exports (retired in epic #1267); callers now import these from their respective leaf modules directly.
Migration plan: Phase 1 (#3465) seam additions complete; Phase 2 (#3466) targets 6 subprocess files; Phase 3 (#3467) targets 15 fs files (215 call sites); Phase 4 (#3468) removes compat exports.

- **Affected this session:** #154, #156, #143, #155, #169
- **Fix:** Add row to `docs/INVENTORY.md` + `node scripts/gen-inventory-manifest.cjs --write`
### Slash command two-tier confusion
- **Symptom:** `tests/bug-2543-gsd-slash-namespace.test.cjs` or `tests/bug-3584-runtime-slash-emitters.test.cjs` fails
- **Affected this session:** #154 (three passes), #164 (added the authoritative matrix)
- **Fix:** Consult `## Slash-command form` section of this file before touching any `/gsd-` or `/gsd:` token — colon for `agents/`/`commands/`, hyphen for runtime emitters
### Concurrency cancel-in-progress masking real CI state
- **Symptom:** `gh pr checks` shows failures but the latest commit SHA's run was cancelled before Tests even started
- **Affected this session:** #154, #136
- **Fix:** `gh workflow run Tests --repo open-gsd/gsd-core --ref <branch>`; verify with `gh run list --branch <branch> --workflow Tests --limit 1 --json status,conclusion,headSha`
### Missing changeset fragment
- **Symptom:** `changeset-lint` fails with `fail_missing_fragment` (~5s)
- **Affected this session:** #156, #143, #164
- **Fix:** `node scripts/changeset/new.cjs --type <Type> --pr <N> --body "..."` or apply `no-changelog` label for doc-only PRs
### Cross-platform Windows / Node 24 hazards
- **Symptom:** Windows CI leg fails; Mac/Linux green — POSIX paths in `node -e`, hardcoded `.nvmrc` fixtures, 2000ms wall-clock budget flakes, `synckit` uncaught Worker exception
- **Affected this session:** #157
- **Fix:** Use `./package.json` not `$PWD/package.json`; write `.nvmrc` dynamically in `before()` hook; use 5000ms budget; wrap `getExecuteForCjs()` in `try/catch`
### Sub-agent rubber-duck stall
- **Symptom:** Sub-agent returns a question list and halts; no commits or push in the worktree
- **Affected this session:** Multiple agents mid-session
- **Fix:** Every sub-agent brief must include: `Skill rubber-duck is BANNED in this sub-agent. Convert to internal monologue and proceed.`
### Stacked PR squash-merge breakage
- **Symptom:** After base PR squash-merges, stacked PR shows conflicts or wrong diff; GitHub auto-retarget fails
- **Affected this session:** #158 stacked on #156
- **Fix:** `git rebase --onto main <old-base> <stacked-branch>` then force-push and `gh pr edit --base main`
### `tee` pipe swallowing exit codes
- **Symptom:** `gsd-test-summary --both 2>&1 | tee /tmp/log` returns `0` even when Docker reports failures
- **Affected this session:** Session-wide risk
- **Fix:** Run un-piped, or `set -o pipefail` before the pipe
### Auto-merge disabled
- **Symptom:** `gh pr merge --auto` returns `GraphQL: Auto merge is not allowed for this repository`
- **Affected this session:** All stacked PRs
- **Fix:** Merge manually by hand in dependency order once CI greens; `gh pr merge <N> --squash --repo open-gsd/gsd-core`
