# Verification: commit 92f614e (Protocol-N reference-integrity guard) — collision check > Snapshot as of 2026-07-16 — focused verification that the commit which landed during > a duplicate-session collision is a SINGLE, CLEAN, CORRECT guard. > Nothing was fixed, committed, or pushed. Verification only. ## VERDICT: CLEAN ✅ `92f614e` is a single, clean, correct guard commit. No duplication, no corruption, no half-merge from the collision. Nothing to do. --- ## 1. Git state — CLEAN - `git fetch` run; `HEAD == origin/dev == 92f614e6baae0fa752fc6e79161fd3c0e66eb5ec`. - Working tree clean (`git status` empty), before and after all verification steps. - `git log --oneline 09c1e73..HEAD` → exactly ONE commit (`92f614e`). - No stashes (`git stash list` empty), no untracked leftovers (`git clean -nd` empty). - `git log --all --grep="Protocol N"` → the guard commit exists exactly once across ALL refs (no second guard commit lurking on any branch). ## 2. Diff coherent and minimal — CLEAN `git show --stat 92f614e` — 6 files, +127/−17: | File | Change | Nature | | ---- | ------ | ------ | | `tests/robco-diagnostics.js` | +111/−1 | the 220.9 guard block + Suite-220 header comment (8→9 tests) | | `CLAUDE.md` | 8 lines | pure 3276→3277 count syncs | | `README.md` | 4 lines | pure count syncs | | `ARCHITECTURE.md` | 2 lines | pure count syncs | | `RULES.md` | 1 line | count sync | | `CHANGELOG.md` | header + 1 entry | Unreleased header 3277/3277 + one plain-English `### Added` entry describing the guard | - **No data files, no CSS, no JS-source, no served/precached file** → no CACHE_NAME bump needed (Protocol 1, correct). - Every changed line accounted for; grep of doc diffs excluding `3276|3277` returned nothing beyond the one changelog entry. ## 3. Guard exists EXACTLY ONCE — CLEAN - One `220.9` block in `tests/robco-diagnostics.js` (lines ~40731–40835), one `assert`. - Identifier census (`protoRefRe220`, `danglingRef220`, `REF_ALLOW_220`, `defineParseOk220`): 13 occurrences, all inside the single block (declarations + uses) — no double-added block. - Repo-wide grep for the guard's signatures (`danglingRef`, `protoRefRe`, "protocol-heading reference") → exactly one file: `tests/robco-diagnostics.js`. ## 4. Runner green, counts synced — CLEAN - `node tests/robco-diagnostics.js` → **ALL 3277 TESTS PASSED** (232 suites), exit 0. - Protocol 2a sync verified: 3277 present in `RULES.md`, `CLAUDE.md` (gate block, note, P4/P5 checklists, Arch Quick Ref), `README.md` (stack table, file-structure comment, workflow, Current State), `ARCHITECTURE.md` (file listing + pre-commit checklist), `CHANGELOG.md` Unreleased header (`Tests: 3277/3277 | Cache: robco-terminal-v2.8.0-r41`). - All other numeric hits are legitimate: frozen released CHANGELOG entries (intentional per 2a), per-suite `// N tests` comments, synthetic fixture strings inside tests (2938/2944), historical prose ("all 3002 tests" in the U-B3 entry — accurate at its landing time), and `tests/test.html`'s own `Suites: 22` runtime-mirror marker (untouched by this commit). ## 5. Guard BITES — red-then-green PROVEN (done fresh, not trusted from the commit message) - **Red:** appended `<!-- collision-verification probe: Protocol 999 -->` to `ARCHITECTURE.md`, ran the runner → exit 1, `1 TEST(S) FAILED (3276 passed)`, failure line: `✗ 220.9: … — DANGLING: 999 (ARCHITECTURE.md)` — names the token AND the file. - **Green:** `git checkout -- ARCHITECTURE.md`, reran → exit 0, ALL 3277 PASSED. - **No false positives:** merged (29/30/31, 32/33/35), retired (15), and forward-ref (47) numbers all confirmed PRESENT in the scanned corpus (`CLAUDE.md`, `ARCHITECTURE.md`, `QUEUE.md`, `RULES.md`, `js/services/cloud.js`, `tests/robco-diagnostics.js`) — so the green run genuinely exercised them and they all resolve. - Self-integrity clause verified in the code: DEFINED-set parse must be ≥40 numbers and contain 1, 46, 33 (proving compound-heading split) and UI-1 — guards against a vacuous empty parse. ## 6. Full gate — GREEN - `npm run gate` end-to-end (lint, format, 3277-test runner, Playwright boot-smoke, render-check, a11y, test.html headless audit, save-survival paths, offline-first network-cut check) → **[GATE] All checks passed!**, exit 0. ## Incident during verification (not repo corruption) - A stale, 0-byte `.git/index.lock` (created 09:47, no `git.exe` process running) briefly blocked the restore step. Removed the stale lock; git operations resumed normally. Assessed as transient lock contention (likely from this session's own parallel git commands), NOT collision damage — the index, refs, and working tree were all intact. ## Actions taken - None to the repo content. Temporary probe in `ARCHITECTURE.md` (bite test) was fully reverted; stale `.git/index.lock` removed. Final `git status`: clean at `92f614e`. - Nothing committed, nothing pushed.
