Summary

Implements ChromelessV2 M0 — the native-peer CI gate. All 9 R# requirements landed; full reform-TDD discipline applied per R#.

  • R1 Gate harness + 2-mode CLI (--scaffold/--strict) + JSON contract (verification/native-peer-gate.mjs)
  • R2 Module-completion config + verdict algebra; ratified gate-blocking schedule encoded as DATA (verification/lib/verdict.mjs)
  • R3 Assertion #1 streamer-page absence + shared image-FS helper (verification/assertions/streamer-page.mjs, verification/lib/image-fs.mjs)
  • R4 Assertion #2 input-bridge / cursor-watcher absence (verification/assertions/bridges.mjs)
  • R5 Assertion #3 codec-cap vs encoder-factory truth, swappable probe strategy (verification/assertions/codec-cap.mjs)
  • R6 Assertion #4 native-peer connectivity probe (verification/assertions/native-peer.mjs)
  • R7 Container-boot + in-netns CDP harness (verification/lib/harness.mjs)
  • R8 Forgejo Actions wiring (.github/workflows/native-peer-gate.yml) + branch-protection compensating evidence
  • R9 integration/native-peer branch (already pushed) + verification/INTEGRATION_BASE.txt anchor

Ratified gate-blocking schedule (encoded as DATA)

# id enablingModule gateBlockingAt
1 streamer-page-absent M7 M7
2 bridges-absent M7 M7
3 codec-cap-matches-factory M1 M1
4 native-peer-connects M3 M3

Source of truth: verification/lib/verdict.mjs::DEFAULT_SCHEDULE. Changing the schedule is a one-line edit.

Test plan

  • Full suite: 76 PASS / 8 SKIP / 0 FAIL locally (84 total).
  • R7 docker-dependent tests SKIP cleanly without docker daemon; exercised in CI via the build-image job.
  • Operator UAT manually verified locally:
    • --scaffold against current source → FAIL (R3 honestly reports streamer-page PRESENT)
    • --strict against current source → FAIL
    • --scaffold against synthetic-clean fixture → PASS with streamer-page-absent: PASS, bridges-absent: PASS, codec-cap: NYI, native-peer: NYI (post-M7 simulation)

Known M0-deferred work

  • R5 current-image-libwebrtc-default.json fixture is a reference placeholder (provenance honest in the JSON _provenance field). MUST be re-captured from a real chromeless:ci image via verification/scripts/cb-encoder-probe-v3.mjs before the M0 PR merges — feedback_test_fixtures_from_real_artifacts requires it. The only honest gap; everything else is grounded in real artifacts (encoder_factory_stub.cc:146 for EXPECTED_FORMATS; on-disk file probes for R3/R4 sanity rows).
  • R8 branch-protection is operator policy (Forgejo admin), not in-repo state. Compensating evidence: verification/scripts/check-branch-protection.sh + verification/README.md#branch-protection. Operator wires the required-check native-peer-gate / native-peer-gate-scaffold.

- Push integration/native-peer branch from main@b438523 (operator-blessed
  base for ChromelessV2 M0-M6 development; M7 squash-merges to main).
- verification/INTEGRATION_BASE.txt records the base SHA for the audit
  trail; verification/__tests__/integration-branch.test.mjs is the
  compensating-evidence E1 anchor (R9 tdd_mode=pragmatic per audit).

Plane: CV2-18 (R9 of M0).
- verification/lib/harness.mjs:
  - boot({imageTag, timeoutMs, env, args}) returns {containerId, wsUrl, client, teardown}
  - per-call CDP via docker exec python3 -c <embedded WS client> (mirrors
    tests/smoke/container-boot.sh — Chromium 147 binds DevTools 127.0.0.1 only)
  - HarnessBootError {code: image-missing | container-exited | ...}
  - HarnessBootTimeoutError {phase: devtools-ready | cdp-<method>}
  - Duck-typed client.send(method, params) -> result; matches the surface
    that R5 codec-cap and R6 connectivity assertions need.
- verification/scripts/with-container.sh: bash-side wrapper exposing
  CONTAINER_ID to the wrapped command, cleanup on exit (trap).
- verification/__tests__/harness-container-boot.test.mjs: 6 RED tests +
  2 always-on error-class shape tests. Docker-dependent tests skip when
  docker daemon / chromeless:ci image absent (locally), exercised in CI.
- verification/__tests__/harness-with-container.sh.test.mjs: 2 RED tests
  for the shell wrapper (cleanup on success AND failure).

Plane: CV2-16 (R7 of M0).
- verification/native-peer-gate.mjs: top-level entrypoint with
  --scaffold|--strict modes, knobs for image/target/timeout/position/
  schedule/source-root, single-JSON stdout contract, human-readable
  table on stderr.
- verification/lib/registry.mjs: assertion contract (id/number/title/run)
  + Status enum (PASS|FAIL|NOT_YET_IMPLEMENTED|SKIPPED) +
  defaultStubAssertions() locking the 4-assertion shape before R3-R6
  drop in real probes.
- verification/lib/verdict.mjs: per-mode verdict algebra (scaffold
  permits NYI for pre-blocking assertions; strict requires PASS) — R2
  fills in the ratified gate-blocking schedule as DATA here.
- Probes are loaded dynamically from verification/assertions/*.mjs;
  missing modules degrade to stub-NYI rather than crashing the gate.
- verification/__tests__/gate-cli.test.mjs: 8 GREEN tests locking the
  IO + exit-code contract; UAT-1 (operator runs locally) deferred to
  M0 closeout once R2-R8 land.

Plane: CV2-10 (R1 of M0).
The ratified gate-blocking schedule (CV2-11 audit) is locked as DATA in
verification/lib/verdict.mjs::DEFAULT_SCHEDULE:
  #1 streamer-page-absent     → post-M7  (deletion-target)
  #2 bridges-absent           → post-M7  (deletion-target)
  #3 codec-cap-matches-factory → post-M1 (encoder factory landed)
  #4 native-peer-connects     → post-M3 (native peer landed)

verification/__tests__/verdict-algebra.test.mjs encodes the schedule as
25 executable assertions across 5 groups:
  1. Table-driven verdict matrix (11 rows): covers ratified current-image
     UAT rows (scaffold/M0+all-NYI→PASS,0 and strict/M0+all-NYI→FAIL,1)
     + post-M1/M3/M7 happy + regression rows + strict honors PASS.
  2. Gate-blocking schedule loader: all 8 position permutations
     (M0..M7) cross all 4 assertions, with the ratified mapping.
  3. Probe-authorship vs gate-blocking decoupling: the executable form
     of the ratified spec resolution (NYI is permissible pre-blocking,
     flips to FAIL once gate-blocking active).
  4. Schema-version invalidator: a stale config is rejected at load,
     guarding against silent drift.

Plane: CV2-11 (R2 of M0).
- verification/lib/image-fs.mjs: shared probeSource()/probeImage() helper.
  probeImage prefers a synthetic manifest fixture (verification/fixtures/
  <safe-name>/image-manifest.json) when present, then docker, then a
  loud SKIPPED with rationale. R4 reuses unchanged.
- verification/assertions/streamer-page.mjs: default source paths
  (capture/streamer-page, capture/streamer-page/index.html) + default
  image paths (/opt/cloud-browser/streamer/streamer.js,
  /opt/cloud-browser/streamer/streamer-page). PASS only when BOTH source
  AND image probe agree absent; image-probe-skipped → conservative FAIL.
- verification/fixtures/synthetic-clean-streamer/ + image-manifest for
  PASS-path test (#3).
- verification/fixtures/chromeless_synthetic-hybrid-streamer/image-manifest
  for hybrid 'source-clean / image-dirty' regression test (#4).
- verification/__tests__/assertion-streamer-page.test.mjs: 6 GREEN tests
  including the ground-truth sanity probe (kills phantom-fixtures class).

Plane: CV2-12 (R3 of M0).
- verification/assertions/bridges.mjs: reuses R3's image-FS helper.
  Inspected-path surface is CONFIG-OVERRIDABLE — pass ctx.bridgesSourcePaths
  (flat list OR split {inputBridge, cursorWatcher}) and ctx.bridgesImagePaths
  to scope to any custom surface. Defaults exposed as
  DEFAULT_INSPECTED_PATHS_BRIDGES + DEFAULT_INSPECTED_IMAGE_PATHS_BRIDGES.
- Evidence splits per-sidecar (inputBridge / cursorWatcher) for downstream
  triage (test #6).
- verification/fixtures/synthetic-clean-bridges/ + matching image-manifest
  for PASS-path test (#3).
- verification/__tests__/assertion-bridges.test.mjs: 6 GREEN tests.

Plane: CV2-13 (R4 of M0).
- verification/assertions/codec-cap.mjs:
  - EXPECTED_FORMATS const, provenance comment 'From capture/encoder/
    encoder_factory_stub.cc:146 GetSupportedFormats() on 2026-05-16'
    (worktree @ b438523d8). VP9 + H264 (profile-level-id=42e01f,
    packetization-mode=1, level-asymmetry-allowed=1).
  - compareCodecs(observed, expected): violation enumeration
    {extra-format, missing-format, parameter-mismatch}. Returns pass +
    violations + normalized observed.
  - Swappable strategy registry: cdp-getCapabilities (default, real CDP
    via R7 client) + sdp-inspection (stub for M1 false-green resolution).
    M1 swap is a one-line config flip; comparator + harness unchanged.
  - NYI shim discipline: pre-enabling-module position returns NOT_YET_
    IMPLEMENTED even if probe wired — preserves scaffold-green contract.
- verification/scripts/cb-encoder-probe-v3.mjs: harness-mode capture
  script for re-generating verification/fixtures/cdp-codecs/
  current-image-libwebrtc-default.json from a live chromeless:ci image.
- verification/fixtures/cdp-codecs/post-m1-expected.json: PASS fixture
  derived from encoder_factory_stub.cc, provenance noted.
- verification/fixtures/cdp-codecs/current-image-libwebrtc-default.json:
  REFERENCE FIXTURE (provenance honest — pre-real-capture placeholder
  per .triform/architecture/chromeless-native-webrtc.md PR #1708; MUST
  be re-captured from real chromeless:ci before M0 PR merges per the
  test-fixtures-from-real-artifacts discipline).
- verification/__tests__/assertion-codec-cap.test.mjs: 9 GREEN tests.

Plane: CV2-14 (R5 of M0).
- verification/assertions/native-peer.mjs:
  - probeNativePeer({target, timeoutMs}) → discriminated result
    ({kind:'ack'|'protocol-mismatch'|'timeout'|'refused'}).
  - Single-handshake TCP wire (HELLO + ACK), JSON frames newline-terminated.
    M3 replaces the wire with real DataChannel/SDP; comparator surface
    (PASS/FAIL + evidence shape) is contractual.
  - Socket destroy() on completion to avoid lingering connections.
  - NYI shim discipline: pre-M3 returns NOT_YET_IMPLEMENTED even with
    target wired (test #6) — preserves scaffold-green contract.
  - Bounded timeouts on all failure modes (no infinite poll).
- verification/fixtures/native-peer-loopback/peer-stub.mjs: three test
  servers (conformant / malformed / silent) with wrap() helper that
  tracks live sockets so close() force-destroys lingering connections
  (otherwise server.close() awaits forever, hanging node:test).
- verification/__tests__/assertion-native-peer.test.mjs: 6 GREEN tests
  including bounded-timeout discipline (test #4 wall-time <5s).

Spec-deviation fix flagged by team-lead on PR #17 review. The verdict
algebra previously propagated explicit FAIL to the gate even when the
assertion was not gate-blocking at the current pipeline position, which
silently re-interpreted the ratified UAT 'scaffold exits 0 against the
current image'.

The whole purpose of the gate-blocking schedule (#1,#2 → post-M7;
#3 → post-M1; #4 → post-M3) was: pre-M7 the gate must NOT block M1-M6
dev pushes on assertions like 'streamer absent' which is impossible
until M7's deletion lands. With the previous logic, R3's honest FAIL
on the current source tree (capture/streamer-page exists) failed every
scaffold run — directly contradicting the UAT and breaking the dev loop
the gate was designed to enable.

Fix (verdict-layer, per team-lead Solution A): in scaffold mode, a
probe contributes to the verdict ONLY when it is gate-blocking-active.
Non-blocking FAIL stays honest in the per-assertion evidence
(JSON.assertions[i].status = 'FAIL', blocked = false) but does NOT
propagate to gate.verdict. Strict mode unchanged — strict ignores the
schedule and requires every assertion to PASS.

Tests:
- New R2 rows:
  * scaffold/M0 + non-blocking FAIL on #1 → PASS,0 (ratified UAT row)
  * scaffold/M0 + non-blocking FAIL on #1+#2 (current-image shape) → PASS,0
  * scaffold/M1 + non-blocking FAIL on #1+#2 + blocking FAIL on #3 → FAIL,1
  * scaffold/M7 + FAIL on #1 → FAIL,1 (M7 regressed)
- R2 row that previously asserted 'M0 + any FAIL → FAIL,1' was the
  silent re-interpretation in test form — corrected to expect PASS,0
  with a comment noting the deviation correction.
- R1 test #2 updated: scaffold with no-blocking schedule MUST exit 0
  regardless of per-assertion FAIL (the load-bearing UAT).
- R8 test #9 updated: scaffold@M0 against current SOURCE → PASS,0 with
  per-assertion #1 still honestly FAIL + blocked=false.

End-to-end UAT verified:
  scaffold@M0 → verdict=PASS exit=0  (assertions honestly show #1/#2 FAIL)
  strict@M0   → verdict=FAIL exit=1  (strict ignores schedule)
  scaffold@M1 → verdict=FAIL exit=1  (#3 gate-blocking flips on at M1)

Full suite: 87 tests, 79 PASS, 8 SKIP (docker-dependent R7), 0 FAIL.

Process note: this was a silent spec deviation I baked into the
implementation instead of flagging as a finding. Future deviations
will be raised before being implemented.

Plane: CV2-11 (R2 of M0, fix-up).

Closing as fully landed — this PR would add nothing.

Evidence on the current tree:

git rev-list --count origin/main..origin/cv2/m0-ci-gate   -> 0
git diff --stat origin/main...origin/cv2/m0-ci-gate       -> (empty)

The three-dot diff is what a merge would actually introduce, and it is empty:
every commit on cv2/m0-ci-gate is reachable from main.

Worth stating because I got it wrong first: the two-dot git diff origin/main origin/cv2/m0-ci-gate is NOT empty (~343 commits of difference), but that measures how
far main has moved since this branch was cut, not what this PR carries. Only
the three-dot form answers the question.

It also targets integration/native-peer, which is no longer the integration
path.

Nothing is lost by closing; reopen if the three-dot diff ever shows content.
