[FORGE-100] feat(reconcile): /reconcile skill + forge orchestrate reconcile verb (P2.5-T09)#164
Merged
Merged
Conversation
Phase 2.5 task IDs (P2.5-T01) and phase IDs (phase-2.5) didn't match the
schema regexes. Live phases.yaml also used `type: skill` / `type: docs` and
`status: deferred-v0.5` / `dropped` / `paused` fields that weren't in
TaskSchema. Result: loadPhases() throws on the very file forge generates
about itself.
- TASK_TYPES += 'skill', 'docs'
- PHASE_STATUSES += 'paused'
- TaskSchema gains optional status + {deferred,dropped,paused}_{at,reason}
- Phase/Task id regex accept decimal phase numbers (P2.5-T01)
- Fix YAML over-escaped backticks in P2.5-T18 description (\\` → `)
Prep work for FORGE-100 /reconcile, which needs loadPhases() to read
phases.yaml as the first step of the diff. Schema patch is additive — no
existing fixtures break.
Decision: Q4 schema-fix-strategy → user chose option B (fix in this PR)
Future verbs (FORGE-100 /reconcile next) need atomic file writes; the init/scaffold.ts private helper now lives in src/core/fs-atomic.ts and scaffold imports it. Adds tmp-file cleanup on rename failure (previous behavior left the tmp behind). Unit tests cover: happy path, nested mkdir, overwrite, no tmp residue on success, tmp cleanup on rename failure.
Pure functions for tracker ↔ phases.yaml sync:
- diffPull(issues, phases) → { updated, removed, added, unmanaged }
* updated: title or depends_on diverges; tracker blockerIds mapped back
to task IDs via the local tracker_issue_id index
* removed: phases.yaml task with no matching tracker issue (orphan)
* added: tracker issue with forge:task footer but no local task
(informational — phases.yaml only gains tasks via /amend-roadmap)
* unmanaged: tracker issue without forge:task footer (created outside forge)
- diffPush(phases, issues) → { bodies, skipped }
* bodies: each (task, phase) → rendered markdown
* skipped: no_tracker_issue_id | orphan_in_phases
- renderTaskBody(task, phase) — markdown shape mirroring live tracker bodies
(metadata header + description + acceptance checklist)
- applyPullToPhases(phases, plan, { confirmPrune }) — updates titles +
depends_on; prunes orphans only when confirmPrune=true; never auto-inserts
added[] (caller must surface them out-of-band)
Decision: depends_on diff sorts both sides before comparison so blockerId
order changes don't generate false positives.
…pull
Live phases.yaml has ~100 comment lines (phase rationale, deferral reasons,
rescope footnotes). Re-stringifying from the parsed Phases shape strips them
all. Per [[validator-narrower-than-preserver-causes-silent-corruption]], the
--pull writer must use yaml.parseDocument and mutate in place.
applyPlanToDocument(doc, plan, { confirmPrune }) traverses the Document tree,
applies title + depends_on updates, prunes orphans when confirmed. Returns
mutation count so the caller can skip the write when zero.
Decision (mid-implementation AUTO): preserve comments via Document API.
Rejected: re-stringify from Phases — loses ~100 comment lines on the very
file forge generates about itself.
CLI surface for FORGE-100 /reconcile. Flat naming matches the 6 existing
orchestrate-*.ts verb files.
Behavior:
- --pull --dry-run: emits {ok, data:{pull:PullPlan, applied:false}}; exits 0
unless orphans present (exit 1 = PRUNE_PENDING).
- --pull (no --dry-run): with orphans and no --confirm-prune|--no-prune,
exits 1 with the plan in stdout and a stderr hint to re-run with one of
the flags. With --confirm-prune, applies updates and prunes orphans via
applyPlanToDocument so phases.yaml comments survive.
- --push --dry-run: emits the rendered bodies without calling the tracker.
- --push: best-effort updateIssueBody loop; each per-task error collected
into failed[]; exits 2 if any failed (PARTIAL_PUSH_FAILURE per plan §Q3).
- --push for tasks without tracker_issue_id: skipped silently.
- Notion --push: gets NOT_IMPLEMENTED from the adapter stub; surfaced via
failed[] like any other per-task error.
Tracker instantiation inline switch on settings.tracker.type. Tests inject
a fakeTracker via trackerOverride so the unit suite has no network surface.
Decision: Q2 partial-push failure → best-effort + summary (user pick).
Decision: Q1 conflict UI → no conflict prompt (SPEC > LINEAR AC).
Decision: Q3 schema → schema patched in earlier commit, --pull reads via
PhasesSchema.safeParse successfully.
Adds 'reconcile' to the orchestrate subcommand switch and usage banner. Verb already self-contained; bin just forwards process.cwd() + subArgs. Smoke: built dist/bin/forge.cjs prints INVALID_ARGS JSON when --pull/--push absent, confirming end-to-end wiring through the bundler.
Skill wraps `forge orchestrate reconcile`: 1. Direction prompt (--pull / --push) 2. --dry-run --json call; present diff summary to user 3. Orphan-prune confirmation when --pull has removed[] (re-invokes with --confirm-prune or --no-prune) 4. Apply (no --dry-run); parse JSON envelope 5. One-line outcome summary + per-task failure listing on --push partial Notes documented in the skill: - Notion --push is a NOT_IMPLEMENTED stub (FORGE-117) - No conflict-resolution UI (SPEC > LINEAR AC per Q1) - YAML comments preserved across --pull writes - Exit codes 1/2 are user-actionable (PRUNE_PENDING / PARTIAL_PUSH_FAILURE)
Behavioral coverage at the CLI verb level driving a shared FakeTracker: - Round-trip: --pull → --push → --pull is idempotent (no diff on round 3) - Unmanaged tracker issue (no forge:task footer) appears in unmanaged[] and is NOT added to phases.yaml - --pull preserves YAML comments + field ordering when applying writes - Orphan flow: dry-run exits PRUNE_PENDING; --confirm-prune actually prunes - --no-prune applies title/depends updates but keeps orphans in yaml Per [[scope-cut-worldview-check-before-multi-adapter-stdlib]]: one FakeTracker against the Tracker interface contract, not three per-adapter runs. Adapter-specific quirks (Notion stub, Linear/GitHub footer parsing) are covered by FORGE-94's tests.
Supersedes the "Conflict prompt fires when same task edited in both places" acceptance line. Per [[spec-beats-linear-ac]], SPEC + the team-mode minimum architecture doc (spec/ORCHESTRATOR.md §CLI surface line 42) override the older AC text: - "Conflict prompt" removed; replaced with diff-preview + --confirm-prune - File path updated: src/cli/orchestrate/reconcile.ts → src/cli/orchestrate-reconcile.ts (flat naming, matches the 6 existing orchestrate-*.ts verb files) - Comment + ordering preservation called out explicitly (yaml.parseDocument) - Integration test AC reinterpreted: Tracker interface contract via shared FakeTracker, not 3 per-adapter runs; per-adapter quirks covered by FORGE-94 tests Decision: Q1 conflict UI → SPEC > LINEAR AC per user answer.
QA on FORGE-100 caught that exit codes 3 (PHASES_NOT_FOUND/INVALID_CONFIG) and 4 (TRACKER_ERROR at listActiveIssues) had no regression test. Two new unit cases cover: - exitCode 3 when plans/phases.yaml is missing (no settingsOverride flag involved — config-loading path) - exitCode 4 when tracker.listActiveIssues() rejects Both error paths emit JSON envelope to stderr per the spec-diff verb pattern. Also notes the --task <id> filter as deferred to FORGE-119 (filed during QA) — none of the locked ACs depend on it and the diff helpers already accept arbitrary inputs, so the follow-up is a thin filter layer.
3 BLOCKs from code-reviewer + 4 MEDIUMs from security-auditor + 1 LOW
addressed in this commit. The remaining LOW (TASK_STATUSES enum widening)
is deferred to a fast-follow per the auditor's verdict.
## Code-review blocks
1. **Exit code collision (BLOCK)**: INVALID_ARGS now exits 3 (hard error),
not 1 (PRUNE_PENDING). A caller checking `exitCode === 1` to decide
whether to prompt for orphan-prune confirmation can no longer mistake a
malformed call for a prune gate. Unit test updated to pin the new code.
2. **MCP handle leak (BLOCK + MEDIUM)**: `createTracker` now returns
`{ tracker, close? }` and `runOrchestrateReconcile` awaits `close()` in
a try/finally. Notion's StdioClientTransport child process is torn down
on every exit path including thrown errors. Linear/GitHub return
`close: undefined` (no-op).
3. **Local-only depends_on corruption (BLOCK)**: if any local
`depends_on` entry pointed to a task without `tracker_issue_id`, the
diff would silently overwrite to the shorter tracker-mapped list,
dropping local-only deps. Now: `diffTaskAgainstIssue` skips the
`depends_on` diff entirely when not every local dep can be represented
on tracker. Regression test added in
`test/unit/orchestrator/reconcile.test.ts`.
## Security MEDIUMs
4. **settings.yaml symlink check**: `validateUnderRoot` is now called on
both `phasesPath` and `settingsPath` before any read/write. Symlinks
pointing outside `cwd` throw `PATH_ESCAPE` and surface as
`INVALID_CONFIG` with exit 3.
5. **phases.yaml write target symlink check**: same as above; covers the
`writeAtomic(phasesPath, …)` call site.
6. **mcp_command unconstrained spawn**: `createTracker` enforces an
allowlist of `{npx, node}` for `mcp_command[0]`. An attacker with write
access to `.forge/settings.yaml` (e.g. malicious CI PR) can no longer
pin the launcher to an arbitrary binary. Out-of-band launchers can be
added to the allowlist if needed.
## Security LOWs
7. **TOCTOU**: `loadPhasesWithDocument` now stat()s the file BEFORE
`readFileSync`, so a 4 MiB+ adversarial file is rejected without
loading into memory.
## Improvements
- Dead code `void titleAndDepsChanges` removed.
- Orphan-pending path: stdout now emits `ok:false` with
`code: PRUNE_PENDING`, stderr carries the full plan (skill consumers
no longer need to inspect data.pull.removed.length to detect).
- `applyPlanToDocument` gains a comment explaining `added[]` is
intentionally skipped (parity with `applyPullToPhases`).
- SKILL.md documents that NOT_IMPLEMENTED and PRECONDITION_FAILED loop
forever — automated retries should filter to RATE_LIMITED/TRANSPORT/
TIMEOUT codes.
## Deferred to follow-up
- LOW: `task.status` schema widening (`z.string().optional()`). Auditor
recommended `z.enum(TASK_STATUSES)`. Deferred because live phases.yaml
uses values like `'deferred-v0.5'` that aren't trivially enumerable;
the right shape needs its own scoping. Filed as a fast-follow.
## Verification
- `npm run typecheck`: clean
- `npm test`: 945 tests, 934 pass, 11 skipped, 0 fail
- `npm run build`: dual ESM+CJS dist
- `npm run test:pack`: 0 forbidden paths in tarball
- Smoke: `node dist/bin/forge.cjs orchestrate reconcile` returns
`INVALID_ARGS` JSON (exit 3), mutually-exclusive flags rejected.
Two independent reviewers (Codex CLI + Claude code-reviewer) flagged
three new BLOCKs on the post-fix PR. All three plus three high-confidence
improvements addressed in this commit.
## BLOCKs
1. **Duplicate forgeTaskId attribution (Codex conf 9)**:
`diffPull` previously fell back from `byTrackerId.get(issue.id)` to
`byTaskId.get(issue.forgeTaskId)` unconditionally. If a malicious or
duplicate tracker issue carried `<!-- forge:task=P1-T01 -->` while the
local P1-T01 already bound a different `tracker_issue_id`, the fallback
would silently apply the duplicate issue's title/deps to the local
task. Now: fall back only when the local task has no
`tracker_issue_id` yet (legitimate first-sync case); a colliding
footer on a different tracker issue surfaces as `unmanaged[]`.
2. **MCP allowlist was security theater (Codex conf 8)**:
The earlier `{npx, node}` allowlist on `mcp_command[0]` did not
constrain anything meaningful: `node -e '...'` and `npx -y
<attacker-pkg>` are both arbitrary code execution. Removed the
allowlist and documented the honest trust model: settings.yaml is
TRUSTED EXECUTABLE CONFIG (same trust level as package.json scripts
or a Makefile). Mitigation lives at the repo layer (branch protection,
CODEOWNERS), not at the argv[0] layer.
3. **YAML anchor splice crash (Claude 2nd-pass)**:
`tasksNode.items.splice(ti, 1)` on a task node carrying a YAML anchor
leaves any `*alias` elsewhere in the document dangling; yaml v2's
`doc.toString()` then throws "Unresolved alias". forge-generated
phases.yaml never uses anchors, but a hand-edited file might. Now:
`applyPlanToDocument` throws a clear VALIDATION error before splicing,
pointing the user to resolve the anchor manually.
## Improvements
- **PRUNE_PENDING stream convention (Codex conf 8)**: stdout now carries
the structured plan envelope and stderr the human diagnostic, matching
`orchestrate-spec-diff.ts`. Previously inverted (error on stdout).
- **Round-trip e2e was a placebo (Codex conf 7)**: `FakeTracker.updateIssueBody`
now actually stores the body, and the round-trip test asserts the rendered
body reached the tracker (Forge task ID, type, owner, depends_on,
acceptance — all present in the pushed body).
- **Local-only depends_on regression test scope (Codex conf 7)**: assertion
narrowed from "no update at all" to "no depends_on change", so a
future title diff on the same task can't mask a real regression.
## New regression tests
- diffPull duplicate forgeTaskId footer → unmanaged (not attributed)
- diffPull forgeTaskId fallback still works when local tracker_issue_id is undefined
- applyPlanToDocument refuses to prune an anchored task
## Verification
- `npm run typecheck`: clean
- `npm test`: 962 tests, 951 pass, 11 skipped, 0 fail
- `npm run build`: dual ESM+CJS dist
- `npm run test:pack`: 0 forbidden paths
- Smoke: `node dist/bin/forge.cjs orchestrate reconcile` returns INVALID_ARGS (exit 3)
