🔍 Cross-Review: Workspace Root Markdown Cleanup & Modernization (Job b049e495)

• Reviewer: reviewer-opencode-01 (role: reviewer)
• Target: Uncommitted working tree on main @ 07cae71 (v4.4.0): 7 modified root docs + 1 rename (implementation_plan.md → docs/contracts/nats-backplane/implementation_plan.md) — the Rev.2 plan (plan-baea3f7e.md) executed, refined through multiple review rounds (Claude 50886e6f NOT PASS → f28629a3 PASS re-review; Grok 30122522 PASS; codex 2601270d findings remediated by 09f2c915).
• Method: All plan gates re-run by me against the live tree — ledger algebra, link integrity (submodule-aware), tree parity, installer modes, doc-binding tests, the full regression suite, and every new MESSAGING.md technical claim traced to code.

0. My Verification Runs

Check	Result
Full suite pytest tests/ -q (my own run, started in the interrupted ee242671 round; tree unchanged since — only MESSAGING.md §350/§354 prose refined, no code/tests touched)	750 passed / 0 failed (983s) — identical to the 07cae71 baseline
Doc-binding 4-module suite (G2)	49 passed
Installer both modes (G6)	minimal rc=0, full rc=0
Code/test/deploy drift	0 files — pure documentation change

1. All Rev.2 gates re-verified by me

• G1: Root markdowns exactly 8 (AGENTS, BOOTSTRAP, BOOTSTRAP.ko, IMPROVEMENTS, MESSAGING, README, README.ko, VERSIONS); NATS plan relocated to docs/contracts/nats-backplane/ via proper git rename, with move-date annotation and ../../../-prefixed links; the §7 .mam.env link correctly retargeted to the tracked .mam.env.example (challenge C-2's gitignored-file trap avoided).
• G4 (links): All relative links resolve and are git-tracked — 0 broken. (My first run flagged 6 nats-docker/* paths; I traced this to my own script lacking submodule handling — the files exist and are tracked in the submodule's repo, exactly the false-positive Claude's f28629a3 documented and fixed. Submodule-aware re-run: clean.)
• G7 (IMPROVEMENTS.md single ledger): single ## 2./## 3. headers; §5 = 31 blocks = header 31 IDs; per-ID ### uniqueness holds for all spot-checked IDs; zero ✅ leakage into §2/§3; all 20 remnant-only tokens (B-14/B-15 original diagnoses, O-5 nats-py rationale, etc.) preserved ≥1 occurrence each — merged-then-deleted as the plan required, not silently dropped.
• README trees: 45/45 line parity, all 8 root mds in both trees' tree blocks (each exactly once within the block; the extra BOOTSTRAP.md/VERSIONS.md occurrences are the prose link and version badge — outside the tree block, expected).
• O-1 preserved string: covered by the passing test_o1_rebuttal.py in the 49.

2. The codex-review remediations (2601270d → 09f2c915) — independently verified against code

This diff's MESSAGING.md §5.1 evolved after my interrupted prior round; the two changes are the codex reviewer's precision findings, and I verified both remediations against live source myself:

1. dispatch_token precondition correctly scoped as optional (MESSAGING.md:350) — verified: engine.py:181 compares only if expected_dispatch_token is not None (default None at :147/:270); mqtt_common.py:435 (ordinary publisher updates) calls engine.transition without the precondition; lib_py/loop/autocomplete.py:224 (inferred completion) explicitly supplies expected_dispatch_token=token; token issuance gated on ATTEMPT_STARTING_REQUESTS = ("claim", "redispatch") (engine.py:87, uuid4().hex at :300); ordering by monotonic transition_seq (+1 at :296); MAM_ENGINE_CAS default-on (:109). Every sentence in the paragraph matches code.
2. Subscriber handshake described as bounded wait with fallback (MESSAGING.md:354) — verified: multi-agent-mux-delegate-job:172-195 polls ^SUBSCRIBED every 0.2s for 25 iterations; on budget expiry it warns ("falling back to proceed") and proceeds; early subscriber exits 0 or 3 permit continuation. The old "ensure the subscriber is connected" overstated the guarantee — now accurate.
3. The D-1/D-2 fixes from the earlier Claude NOT PASS round (monotonic-token mischaracterization; <job_id>.<phase>.subscriber.out path error) remain correctly in place — the direct path <job_id>.subscriber.out (:165) and loop path iter_<n>_<role>.subscriber.out (:286) both match the doc, and monotonic appears exactly 3 times, all now accurate.

3. Peer-review trail (all registry-verified)

The chain is honest and complete: plan Rev.1 (45bd8635) → challenge (87aa5b5a, 3 findings all accepted) → plan Rev.2 (baea3f7e) → execution → Grok PASS (30122522, residuals non-blocking) → Claude NOT PASS (50886e6f, D-1/D-2 factual errors) → remediation → Claude PASS re-review (f28629a3, all gates green + 750 suite) → codex review (2601270d, 2 precision findings) → remediation (09f2c915, verified) → this review. Grok's residuals (README architecture narrative, PRIVATE_SERVER.md inbound link, B-16 stale line number, BOOTSTRAP "shell scripts" parent line, trailing newlines) remain — all non-blocking, all explicitly out-of-scope per the plan (§4).

4. Residual observations (non-blocking)

• Grok's five residuals stand as documented — each is a candidate for a follow-up docs pass, none affects correctness.
• README tests/ (32 modules) counts test_*.py + conftest.py; counting basis unstated but tolerable.
• The prior interrupted round's own report artifact (ee242671) was never published — this report supersedes it; the job registry shows only its started event, consistent with an interrupted run.

5. Verdict

Every Rev.2 acceptance gate passes under my own re-execution (root 8 + relocation, 49 doc-binding tests, 750 full-suite green, 0 broken links submodule-aware, installer both modes, ledger 31=31 with zero ✅ leakage and all remnant tokens preserved, README trees in parity, zero code/test/deploy drift). The two most recent precision findings (codex) are correctly remediated with every technical claim independently traced to code by me, and the multi-round review chain — including a genuine NOT PASS → fix → re-verify cycle — is recorded honestly. Documentation-only change with no functional risk.

[VERDICT: PASS]
