Certify pm CLI 2026.9.21 and adopt the canonical pm-ops lint, duplication and merge-driver gates by unbraind · Pull Request #112 · unbraind/pm-graph

unbraind · 2026-09-23T00:16:09Z

What

pm-graph moves to pm CLI 2026.9.21 (pm-changelog and pm-ops at 2026.9.18) and adopts the canonical pm-ops gates:

Lint: scripts/lint.ts wraps pm-ops/eslint and runs in CI and in release:check.
Duplication: scripts/duplication-gate.ts wraps pm-ops/duplication at a 0% threshold. It was at 5.6%. Shared workspace and harness setup became documented helpers with multiple call sites (for example withCommandWorkspace, runContractCommand), and duplicated import blocks were removed.
Merge driver: scripts/prepare-merge-driver.ts is now the thin launcher over pm-ops/merge-driver.
- The vendored implementation is gone, so its 13 unit tests go with it: POSIX/Windows PATH resolution, the installer, the entry guard. That logic lives in pm-ops, which tests it.
- A new test proves the launcher delegates to the canonical export.
8 type aliases and 3 functions gained docstrings.
The branch is rebased onto today's Dependabot merges (chore(deps-dev): bump @types/node from 26.5.1 to 26.6.2 #107, chore(deps-dev): bump pm-ops from 2026.9.13 to 2026.9.18 #108, chore(deps-dev): bump pm-changelog from 2026.9.16 to 2026.9.18 #109, chore(deps): bump the codeql-action group with 2 updates #111).

Evidence

I reran this independently after the agent's run:

npm run release:check: exit 0, 287 pass, 0 fail, duplication 0% (0/11,842 lines, 46 sources).
There are no lint suppressions, coverage ignores or threshold changes, and no any.
pm health --strict-exit: exit 0.

Known, tracked separately

The merge-driver launcher still statically imports the devDependency pm-ops, so an --omit=dev source checkout fails in prepare. That's fixed in Ship a guarded merge-driver launcher so omit-dev clone installs complete pm-ops#119 (a shipped guarded template) and adopted with the next pm-ops pin bump. Hub item pm-cli-website-xy19.
Supersedes chore(deps-dev): bump @unbrained/pm-cli from 2026.9.17 to 2026.9.19 #110 (pm CLI 2026.9.18).

pm items

pm-graph-yuzr: certify 2026.9.21 and adopt the canonical gates.

Summary by cubic

Certifies pm CLI 2026.9.21 and replaces the vendored merge-driver, lint, and duplication logic with the canonical pm-ops gates.

Gates

scripts/lint.ts and scripts/duplication-gate.ts are thin launchers over pm-ops/eslint and pm-ops/duplication, wired into CI and release:check.
Duplication sits at 0% (down from 5.6%); shared workspace and harness helpers moved to test/helpers.ts, and duplicated import blocks were removed. Also fixed a shared helper, captureStdoutThrow, that was swallowing its own failed assertion and reporting a pass.
Fixed the any casts in tests against real neo4j-driver types, added docstrings to 8 type aliases and 3 functions, and dropped nine dead declarations flagged by DeepScan.
Two of those declarations were assertions the tests promised but never made: topo-sort now verifies Beta precedes Gamma, and analyze --root verifies the neighborhood is exactly the root plus its one-hop dependent.

Merge driver

scripts/prepare-merge-driver.ts is now a launcher over pm-ops/merge-driver; the vendored implementation and its 13 unit tests are gone, replaced by a test that proves delegation.
The Windows prepare-lifecycle CI job is restored: npm ci runs the launcher through cmd.exe, and pm health --strict-exit --require-merge-drivers fails unless the drivers registered.
The Windows integration test drives pm-ops' runPrepareMergeDriver through a real cmd.exe with a pm.cmd shim in a directory holding spaces and a literal %USERNAME%, asserting the shim received exactly merge install.

Known and tracked separately: the launcher still statically imports the pm-ops devDependency, so an --omit=dev checkout fails in prepare; resolved with the next pm-ops pin.

^{Written for commit b2035c0. Summary will update on new commits.}

Adopt pm CLI 2026.9.21, pin @unbrained/pm-cli 2026.9.21 / pm-changelog / pm-ops exactly, absorb Dependabot bumps, add canonical lint (pm-ops/eslint) and duplication (pm-ops/jscpd) gates with zero findings. Duplication eliminated by extracting genuinely shared logic: - test/helpers.ts: withNeo4jQueryTest, withCommandWorkspace, setupChainWorkspace/CycleWorkspace/BareWorkspace, activateWithRecording, captureStdoutThrow, expectCommandError/Multi, expectExporterReject, runExportRaw, createChain, synthNode/Rel/Graph, NEO4J_FAIL_ENV, setNeo4jTestEnv, applyEnv, CmdResult/CommandError types - src/index.ts: unwrapNeo4jInteger, nodeLabelParts, orderedNodeSet, collectBidirectionalEdges, loadShapedAnalytics, wrapCommandError - Added docstrings to 8 type aliases and 3 functions Lint: 0 errors. Duplication: 0% (0 clone pairs). Tests: 287 pass. Coverage: 100/100/100. pm health --strict-exit: exit 0.

- Added CI verification that merge drivers are installed and required for health checks.
- Exposed graph-related types for improved extension and integration support.
Bug Fixes
- Improved Neo4j loading and retry behavior, including clearer error handling.
- Preserved command errors without unnecessary re-wrapping.
Documentation
- Clarified merge-driver setup, registry installation behavior, and production installation requirements.
Tests
- Expanded and strengthened coverage for analytics, exports, diagrams, Neo4j integration, and Windows workflows.

Walkthrough

The PR adds canonical lint and duplication gates, delegates merge-driver setup to pm-ops, consolidates runtime helpers, and exports shared graph types. It also centralizes test helpers, converts Neo4j fixtures to synchronous resolve hooks, and refactors command and integration tests.

Changes

CLI certification and quality gates

Layer / File(s)	Summary
Certification records and quality gates `.agents/pm/`, `.github/workflows/ci.yml`, `README.md`, `package.json`, `scripts/`	Adds task certification records, canonical lint and duplication gates, CI enforcement, updated dependency pins, and `pm-ops` merge-driver delegation.
Runtime loading and analytics consolidation `src/index.ts`	Adds lazy CommonJS Neo4j resolution, exported graph types, shared error and numeric helpers, shared renderer labels, impact-subgraph helpers, and common analytics loading.
Typed analytics test fixtures `test/analytics.test.ts`	Replaces manually shaped graphs and `any` casts with typed graph fixtures while preserving the existing analytics and renderer assertions.
Shared test infrastructure `test/helpers.ts`	Adds shared workspace, command, environment, fixture, fake npm, output-capture, cleanup, and assertion helpers.
Command and contract test migration `test/command-surface.test.ts`, `test/coverage-gaps.test.ts`, `test/diagram-commands.test.ts`, `test/edge-cases.test.ts`, `test/explain-command.test.ts`, `test/export-and-contract.test.ts`, `test/id-resolution.test.ts`, `test/impact-command.test.ts`	Migrates tests to shared helpers, typed result shapes, reusable workspace setup, centralized error assertions, and shared cleanup.
Neo4j loader and lifecycle test migration `test/fixtures/`, `test/neo4j-.test.ts`, `test/prepare-merge-driver.test.ts`, `test/smoke.test.ts`, `test/windows-prepare.integration.ts`	Types fixture resolvers with `ResolveHookSync`, uses `registerHooks` and shared Neo4j query setup, and updates merge-driver and smoke coverage for the new launchers and exported types.

…ller The certify refactor deleted the windows-prepare-lifecycle CI job together with the vendored installer its integration test imported, leaving the README's POSIX/Windows equivalence claim unverified. The job is back: npm ci runs the thin launcher through cmd.exe, pm health --require-merge-drivers fails unless that registered the drivers, and the integration test drives pm-ops' runPrepareMergeDriver through a real cmd.exe with a pm.cmd shim in a directory named with spaces and a literal %USERNAME%, asserting the shim received exactly 'merge install' (Greptile review on #112).

@greptileai review

DeepScan reported 9 new issues; tsc --noUnusedLocals --noUnusedParameters reproduces exactly nine. Two were assertions the tests promised but never made: topo-sort now also asserts Beta precedes Gamma (its comment said so), and analyze --root asserts the neighborhood is exactly root plus its one-hop dependent instead of 1..2 items. The rest were dead: two destructured bindings in topo-sort (flags, graph), two unused tmpdir imports, an unused t2/b binding, and an unused main import.

In `@scripts/prepare-merge-driver.ts`:
- Line 8: Update the prepare script around runPrepareMergeDriver so pm-ops is
resolved lazily or guarded at runtime instead of through a static import. Ensure
npm ci --omit=dev can execute prepare without the development dependency, while
preserving merge-driver registration when pm-ops is available and the existing
no-op behavior otherwise.

In `@test/diagram-commands.test.ts`:
- Around line 20-22: Update assertCycleFormatThrows to remove the outer
try/catch and directly inspect the outcome returned by captureStdoutThrow.
Assert that outcome.error is defined, then match its message against /dependency
cycle/i before returning outcome.stdout, so assertion failures are not converted
into successful cycle detection.

captureStdoutThrow returns the handler's error instead of throwing it, so the helper's catch only ever caught its own failed assert.match and turned it into a pass. With the expected message changed to one the command never prints, both cycle-format tests still passed. The helper now asserts on outcome.error directly, and the same change fails both tests. The swallowing pattern predates this branch (two copies on main, merged into this helper by the deduplication) (CodeRabbit review on #112).
