Phase V — Second Independent Verifier (Verifier B) — report + loop-1 addendum, verbatim

Provenance note (orchestrator, not the verifier): two sessions raced this mission on completion-run; each independently spawned an adversarial Phase V verifier. Verifier A's report is V_verifier_report.md (landed with c11eb2e). This file is Verifier B's report and its loop-1 re-check addendum, reproduced VERBATIM below (basis SHAs are pre-merge: adc5e6c for the report, ffac680 for the addendum). The two lanes' fixes were then union-merged in 37dbb43, and a final loop-2 verification ran on the reconciled tree — its addendum is appended at the end of this file when complete. Everything between the rules below is the verifier's own text, unedited except one rendering-only normalization: the verifier ended each report with an EMPTY fenced code block (its literal empty porcelain output), which breaks Markdown rendering for the rest of the file — those bare fence pairs are replaced with an italicized "(no output)" line. No other character of the reports was altered.

Phase V — Independent Adversarial Verification Report

0. Verification basis

• Branch/SHAs (verified, not trusted): git branch --show-current = completion-run; HEAD = adc5e6c54019a34aae7dc1578e0c98ba78d211e2. git merge-base ef5ae95 HEAD = ef5ae95108df3378e7d1912d323bf2385a141700 (exactly ef5ae95's full SHA — the PR diff is git diff ef5ae95 HEAD). Pristine main worktree at the scratchpad main-check path: git rev-parse HEAD = ef5ae95108df3378e7d1912d323bf2385a141700 ✓.
• Diff stat: 76 files changed, 9,006 insertions(+), 77 deletions(−). Branch-only commits: 9551ace, 0769a77, 98b9d5f, d910eed, a5349cf, 40560c8, bb1b27a, 1242794, a74e8de, 6a1f7e3, adc5e6c (plus the merge of origin/main).
• Environment: python 3.11.15, pytest 9.1.1, cov-7.1.0. Installs made by me: pip install -q scikit-learn (installed 1.9.0 — needed to even attempt the ledger-cited lift-engine suite). Invocation nuance used: PYTHONPATH=/home/user/MIZOKICloudRun/contracts for tests/remediation/test_contracts_hardening.py (imports mizoki_contracts), and lift-engine run from its service directory (imports src.core.*).
• Refused as evidence: PR #638 body/comments, all builder summaries, commit messages, and ADR/RUNBOOK prose (checked only for existence/consistency). A1/A2/A3 audit files were opened only to locate claim page anchors (C24–C26, C39, C41–C45 line references); every behavior claim below is verified against code I read, tests I ran, and page text I extracted.
• Method notes (transparency): my first rule-A seed and first constant-mutation both silently no-opped (sed pattern mismatch); both were redone with grep-verified application before judging. All conclusions below are from verified-applied experiments.

1. Content QA vs independent grep (Task 1)

Tool runs (from # MIZ OKI 3.5/): python3 scripts/content_qa.py → CONTENT QA OK — 25 scoped files clean, exit 0. --self-test → 16/16 seeded classes CAUGHT (A banned strings incl. quokka/KL/sub-N-ms, B intent+net-yield preview framing, C number label, D §-sequence, E(a)–(d)), clean fixtures 0 findings, exit 0.

Independent case-insensitive greps over ALL of # MIZ OKI 3.5/**/*.html (85-file universe incl. unscoped marketing/, media/), executive-briefing/js/*.js, docs/marketing/*.md, blog/**:

Residual observation (not a violation found): 11 served marketing/*.html pages and all media/** pages are outside content_qa scope (only marketing/governance.html is scoped); today they are clean under the tool's own regexes, but nothing gates them going forward.

2. Claims verdicts (Task 2)

Suites backing these verdicts are the runs in §3 (192 rails, 110 claims-backing, 27 cell36, 15 identity, 22 envelope, 13 contracts-hardening, 60 cell34, 59 net-yield, 427 site). "pack" = tests/claims_backing/.

Ledger/BUILD_DEBT two-way cross-check (independent script): 32 ledger rows; every evidence: path exists on disk (0 missing); cited debt ids {AU-1, CL-26, CMEK-1, GB-1, LEG-1, RF-1, RL-1} all have BUILD_DEBT rows; every BUILD_DEBT row is cited by the ledger (0 orphans); meta.page_coverage fully satisfied; the strict subset parser's output is exactly equal to PyYAML's on the real ledger. Gap on the other axis: coverage is self-declared, so C39/C41 on shopify.html and C24–C26/C45 have no rows at all — structurally invisible to rule E(d).

3. Test suites & flag enforcement (Task 3)

Flag flip-tests: - NET_YIELD_WRITEBACK=true python3 -m pytest services/net-yield/ -q → 2 failed as required: test_api.py::TestApi::test_health_reports_writeback_off and test_api.py::TestApi::test_metrics_exposes_counters_and_flag (metrics text shows net_yield_writeback_enabled 1). Enforced. ✓ - MEASUREMENT_WRITEBACK=true python3 -m pytest services/measurement-rails/ -q → 192 passed — stays GREEN → mission-defined FAIL finding. Root cause (code-read): every rails test class (test_flags.py, test_main_api.py, test_writeback_rails.py) runs _clear_env() / os.environ.pop(MEASUREMENT_WRITEBACK…) in setUp, so ambient env can never fail the suite; test_env_true_enables even asserts env=true enables (the operator path). The deeper property does hold in a different form, which I proved by experiment: flipping the code literal WRITEBACK_DEFAULT = False → True fails 9 tests loudly (test_literal_defaults_pinned_in_code asserts both the value and the source text, plus 8 behavioral tests incl. test_send_refused_while_writeback_flag_off, test_health_reports_claim_label_and_flags_off). So the shipped default is pinned against code tampering, but the mission's env-flip criterion is unmet — net-yield has an ambient-env sentinel, measurement-rails does not.

Per-module dry-run guard trace (grep for requests|httpx|urllib|socket across all non-test rails + net-yield modules: zero network imports anywhere — sole hit is urllib.parse (URL parsing only) in net-yield/order_economics.py; the word "requests" in the Google module is docstring prose):

In flag-off state no HTTP call is reachable in any module: the only callable that touches a network is an injected transport, and every path to it passes a raising guard first.

4. Seeded violations & structural checks (Task 4)

All seeds were verified-applied (grep count = 1) before judging; each was reverted with git restore and porcelain confirmed empty after every seed.

Bonus mutation probes: coded uplift-floor default "0.05"→"0.07" in autonomous_budget_reallocation_mvp.py → 2 pack tests failed (test_c27_default_gate_constants_…, test_c27_passing_edges_funded_…); WRITEBACK_DEFAULT=True in flags.py → 9 tests failed. The pins assert real behavior; no rule class passed silently.

Structural checks: - §-sequence integrity: all 7 sec-mark pages strictly 1..N (signal 1–9, thresholds 1–6, budget 1–6, creative 1–4, audiences 1–5, measurement 1–4, shopify 1–6). ✓ - Links/anchors (five dossiers + /signal + index + pricing + shopify, script-checked): all same-page anchors resolve; all internal links resolve to files or verified Flask routes (/contact app.py:743, /demo/counsel:711, /favicon.ico:761, feeds); the K1 fix (/#platform→/#what, /#governance→/#control) verified against real index ids. Zero broken. ✓ - Story bank: v1.1 header + all five rules in both homes; drop/signal-story-bank-v1.1.md and # MIZ OKI 3.5/docs/marketing/signal-story-bank.md are md5-identical (17ca73b7…); positioning doc also identical in both homes. ✓ - Pointers: TRUTH.md §6.6 binds customer-story copy to the story bank; site CLAUDE.md points to it twice (governance pointer + coding guideline 5). ✓ - Canon: check_design_canon.py → CANON OK — 20 core surfaces match (re-pin landed with the copy edits). ✓ - Merge check: git merge-base --is-ancestor HEAD origin/main fails (exit 1) ✓; none of the 11 branch-only SHAs appear in git log origin/main --oneline -30 ✓. - Deploy-evidence (tree-level only): no .github/** edits, no terraform/tfstate files in the diff; programmatic test of every workflow on.push.paths filter against all 76 changed files → 0 matches (the diff is router-inert; services/measurement-rails/cloudbuild.yaml is a new in-service manifest, referenced by no workflow). Deploy checks from inside the repo are necessarily tree-level; live state was not probed. ✓

5. Findings

FAIL findings (builder action needed): 1. FAIL — MEASUREMENT_WRITEBACK env-flip run stays green (mission criterion violated). MEASUREMENT_WRITEBACK=true pytest services/measurement-rails/ → 192 passed. Cause: uniform _clear_env() test isolation. Mitigating fact (proved): flipping the code default fails 9 tests. Fix: add an ambient-env sentinel test like net-yield's test_health_reports_writeback_off. 2. FAIL — C34 ledger cites a failing test. claims-ledger.yaml C34 evidence services/lift-engine/tests/test_causal_reasoning.py fails against its own module (signature drift; 23F/3P; the cited Thompson test fails). Pre-existing on main, but the branch-authored ledger asserts it as backing. Fix: repair the lift-engine tests, or add a Thompson pin to the pack, or re-cite. 3. FAIL — C24/C25/C26 unpinned and unrowed. Matrix §2b promised B5 pins for "$50 floor; 80/85/15% defaults"; no test pins them (repo-wide grep) and no ledger rows exist. Constants verified honest to code by inspection (relu_threshold_agents.py:70/71/77), labels present on-page. 4. FAIL — C41 "Prove is live" (shopify.html §05): unhedged liveness claim; matrix-promised ledger row (citing live-verified memory records) was never created; unverifiable from the tree. 5. FAIL — C45 ledger row missing: matrix promised "ledger records basis" for the 13-connector/650+ stat row; no row exists (the GA4 tile + count change did land correctly). 6. FAIL (policy deviation, owner adjudication) — C20: signal.html retains present-tense "Budget reallocation reads from this ledger" with wiring absent; RL-1 registered but the verbatim build-to-claim policy requires an on-page relabel that the owner-approved matrix resolution omitted. 7. Finding — C38 tail clause: signal-audiences.html §02 "…and the measured version written back after" present-tense; AU-1 registered, page unlabeled. 8. Finding — ledger coverage gap on shopify.html: page_coverage lists only C40; the §04 "experiments on your actual spend" (C39) and §05 "Prove is live" (C41) machinery claims are invisible to rule E. Rule E(d) is structurally blind to claims on pages not self-declared in the map. 9. Finding — C23 wording: signal-thresholds.html §02/§05 say "knowledge graph"; the tested store is the relu_playbook_patterns Firestore collection, and the ledger's own note mandates "pattern library" wording that never reached the page.

PASS highlights (attempted refutations that failed): content_qa clean + 16/16 self-test; zero real banned strings anywhere in the 85-file universe including unscoped files; all 7 seeded violations caught with file names; two-way ledger/BUILD_DEBT cross-check perfect (0 missing paths, 0 phantom/orphan debt ids); subset parser ≡ PyYAML; every dry-run guard traced to a raising gate with zero network imports; net-yield flip enforced by 2 named tests; constants mutation-tested as genuinely pinned; §-sequences, links, story-bank parity, pointers, canon all clean; diff is router-inert and merge-free.

Pre-existing-on-main attributions (not branch FAILs): - Site suite: 2 homepage failures (test_homepage_serves_teaser_and_driver, test_every_page_declares_the_icon_set) — identical at ef5ae95. - test_virtuoso_models.py::TestJourneyEvent::test_schema_hash_matches_deployed_service — identical at ef5ae95. - services/lift-engine/tests/test_causal_reasoning.py drift (23F) — identical at ef5ae95; lift-engine untouched by the branch (0 diff lines). Becomes branch-relevant only via Finding 2's citation.

Not reproducible / variances noted: K2 was resolved by removing the two og-image references from posts.json rather than generating assets (matrix offered generate-or-repoint; removal also stops the 404s — acceptable variance). M1's "nightly" is a job + RUNBOOK schedule, operator-created — disclosed, not observed. Installs recorded: scikit-learn 1.9.0.

6. Verdict

Overall: PASS with 5 required fixes and 1 owner adjudication. The core build holds under adversarial testing: the measurement-rails service is real, 96%-covered, transport-injected, and refuses to send in shipped state by construction; the claims machinery (rule E + ledger + BUILD_DEBT) is internally consistent both ways and every seeded violation class fires; the B2 copy fixes all landed exactly as specified; nothing from the branch is on main and the diff triggers no deploy path.

Builders must fix: (1) add an ambient-env sentinel test so MEASUREMENT_WRITEBACK=true fails the rails suite; (2) C34's failing cited test (repair or re-cite with a passing Thompson pin); (3) pin C24/C25/C26 constants and add their ledger rows; (4) add the promised C41 row or hedge "Prove is live"; (5) add the promised C45 basis row. Owner adjudication: C20 (and the C38 tail / C39 / C23 wording) — relabel the unbuilt clauses per the verbatim policy, or explicitly ratify the matrix's keep-present-tense-with-debt-row resolution.

Not verifiable from inside the repo: live deploy/serving state (C41 "is live", C39 "your actual spend", "650+ tools" live count, mizoki3.com parity, nightly schedules, IAM lock state) — tree-level checks only, stated as such throughout.

7. Tree hygiene

Final git status --porcelain output (empty — no edits survive; nothing was committed, pushed, or dispatched):

(no output — the porcelain check printed nothing)

Phase V — Re-check addendum (loop 1)

Basis (verified, not trusted): branch completion-run, tip ffac680 → 8e8e4d5 → adc5e6c (git log --oneline -3 matches); working tree clean on arrival; git diff adc5e6c HEAD --stat = exactly the 8 claimed files (+326/−13) — nothing else touched; merge-base with ef5ae95 unchanged; git merge-base --is-ancestor HEAD origin/main still fails (exit 1). All bytecode/pytest caches purged before any scored run, re-purged after each mutation probe, and at the end.

Bytecode-cache incident (my side): Accepted as my process fault. My C27 probe ("0.05"→"0.07") was byte-length-preserving and the git restore landed within the same mtime second — CPython's mtime+size .pyc validation cannot detect that, so a stale cache serving the mutated constant is exactly what that sequence produces. I could not re-observe the poisoned state (orchestrator purged it), but I verified the clean end-state from a fresh interpreter: DEFAULT_THRESH_UPLIFT imports as 0.05, matching source line 102 — confirmed again as the final act of this pass. Protocol adopted: purge before scoring, purge after every probe, fresh-import spot-check at close.

Full re-runs at tip: content_qa → 25 scoped files clean, exit 0; --self-test → PASS. Claims-backing pack → exit 0 (126 dots = 110 + 16 new). Site suite → 428 passed, 2 failed — exactly the two pre-existing base failures I attributed to ef5ae95 in pass 1. Canon → CANON OK — 20 core surfaces match; I independently confirmed the coordinator's canon claim: the files map pins 20 entries and contains none of signal.html / signal-audiences.html / signal-thresholds.html (my initial grep hit was the locked annotation prose, not a file entry), so no re-pin was required. Two-way ledger/BUILD_DEBT cross-check: 38 rows; 0 evidence paths missing (including the quoted "# MIZ OKI 3.5/tests/test_content_qa.py" entry, which resolves on disk); debt ids clean both directions; strict subset parser output == PyYAML exactly; check_claims_ledger on the real tree → zero findings.

New regressions: none found. Nothing outside the 8 declared files changed; no .github/terraform/deploy paths touched; the diff remains router-inert.

Overall verdict: PASS. All six FAILs and findings 7/9 are resolved with evidence I reproduced myself; finding 8 is resolved for every currently-declared page with the E(d) structural blindness honestly left open and recorded here. The standing, correctly-disclosed limits are unchanged: C41 liveness and C39 "your actual spend" are engagement/deploy facts the tree cannot re-verify — both now say so in the ledger.

Tree hygiene: final git status --porcelain output (empty), bytecode/pytest cache directories remaining: 0, fresh-import DEFAULT_THRESH_UPLIFT = 0.05 matches source:

(no output — the porcelain check printed nothing)

Phase V — Final union verification (loop 2)

Reconciliation structure (verified by measurement, not trusted): tip 6f466c7 → union merge 37dbb43 (parents = ffac680 [Lane B, my verified loop-1 tip] + 5b1d6a7); 5b1d6a7 = merge of origin/main (bcd025f) into Lane A (c11eb2e ← 885d92c ← adc5e6c) — both Lane-A commits confirmed in HEAD ancestry (merge-base --is-ancestor exit 0 for each). Tree clean on arrival; all bytecode/pytest caches purged before every scored run.

1. Lane-A fixes intact — PASS. signal.html:241 reads exactly "Budget reallocation is designed to read from this ledger — never from platform-reported ROAS alone."; signal-thresholds.html says "playbook pattern store" at both spots (:264, :316 — no "knowledge graph", no "pattern library"); marketing/index.html proof strip: caption "Signal Latency — design target" beside the <100ms figure (co-presence confirmed through content_qa's own sectionizer: label True in that section); OBSERVED_PERF now carries the (?:&lt;|<)\s*\d+\s*ms\b arm and --self-test reports unlabeled <N-ms latency: CAUGHT. Judged variance, recorded: the union kept Lane-A's shorter C20 sentence — my loop-1 "(operating design)" tag is gone, but "is designed to read" is itself the design framing and the merged ledger C20 note was amended to match ("the page sentence is design-framed to match") — no unbacked present tense remains. Standing observation unchanged: marketing/index.html is still outside the 25-file scope (pre-existing posture; the label fix there is voluntary, the new regex arm gates scoped pages).
2. Lane-B fixes intact — PASS. Rails normal = 194 passed; MEASUREMENT_WRITEBACK=true run = 1 failed: TestAmbientShippedState::test_ambient_environment_ships_writeback_off; ledger C34 evidence cites tests/claims_backing/test_c34_bandit_pins.py = True and the drifted services/lift-engine/tests/test_causal_reasoning.py = False; C39 row exists with shopify coverage [C39, C40, C41]; signal-audiences.html:260 tail ends "— operating design, in development."; StatTileBasisTestCase present and passing (1 passed standalone, and inside the 428).
3. Evidence unions correct — PASS. C24/C25/C26 each cite BOTH test_c22_c23_relu_threshold_agents.py AND test_c24_c25_c26_budget_defaults.py (union kept both pin sets — Lane-A's 4 config-value pins landed inside the c22_c23 file alongside my lane's 7-test file); C41 evidence includes the memory-archive record (on disk); C45 includes the quoted "# MIZ OKI 3.5/tests/test_content_qa.py" entry (resolves on disk); duplicate claim ids: NONE (38 rows); the enforcing ledger test file run from repo root: 20 passed.
4. Union gates, fresh — PASS. content_qa scan 25 scoped files clean (exit 0) + self-test PASS; canon CANON OK — 20 core surfaces (none of the three edited dossier pages is canon-pinned, re-confirmed); site suite 428 passed + exactly the 2 pre-existing base failures I attributed to ef5ae95 in pass 1; claims pack exit 0, 130 tests; rails 194 + flip enforced (item 2); net-yield 59 passed; two-way ledger/BUILD_DEBT cross-check: 0 missing evidence paths, debt ids clean both directions, 0 uncovered coverage ids, check_claims_ledger on the real tree = zero findings; strict subset parser output == PyYAML exactly on the merged ledger.
5. Merge safety — PASS. After a fresh git fetch origin main: git merge-base --is-ancestor HEAD origin/main fails (exit 1); git diff 5b1d6a7 HEAD --name-only = 8 files with zero .github/terraform/tfstate/deployment paths. Noted for the record: 5b1d6a7 also merged newer origin/main content into the branch (UI base-url drain, memory rollover, skills-acceptance files) — that is main's own content arriving via merge, and the reconciliation delta I measured introduced no deploy-path changes.

Regressions found: none. The single wording variance (C20's literal tag → design-framed sentence + amended ledger note) is internally consistent and judged acceptable, recorded above rather than silently absorbed.

Tree hygiene: final git status --porcelain output empty (exit 0 printing nothing), cache directories remaining: 0.

FINAL VERDICT — completion-run branch: PASS. The union lost neither lane's fixes; every gate, pin, flip-test, and cross-check holds at 6f466c7 by direct re-measurement; nothing has merged to main; the only standing limits are the honestly-disclosed ones (deploy-state liveness claims tree-unverifiable; rule-E(d) blind to never-declared pages; marketing/* mostly outside content_qa scope) — all recorded in the ledger notes and my three reports.
