A value deny-list (`disable`/`allow`/`prefer`, MySQL `DISABLED`/`PREFERRED`, `Encrypt=no`/`0`/`false`/`off`) now sits beside the key regex, in ONE shared classifier the posture readers import rather than restate. The encrypted-but-unverified class (`sslmode=require`) is deliberately NOT classified and the reason is written at the constant. The warning also named no connection; both directions now name themselves, `Source` gaining an optional `name` the runner fills. Two readers joined `accepted_cleartext_hops` โ€” `expiry_relaxed_hops` (the flag lands in `spec.settings`, not a typed field) and `unverified_generic_db_hops`, which walks **inbound as well as outbound** because a `DatabasePoll` crosses the same hop with the same credential in the same DSN. Both are **required** parameters on `security_loosenings()` per its own rule that an optional parameter is a detector that silently fails to fire; all four call sites updated, and both graphless callers now name all three connection-scoped deviations in their scope marker (naming only `cleartext_accepted` made the *declared scope* itself incomplete). Advisory `tls-allow-expired` and `generic-db-tls` CheckResults sit beside `_check_cleartext_accepted`. **Ten** DEPLOYMENT.md assertion sites were rewritten, not the five the item predicted โ€” enumerated by grep against the shipped file; eight became outright false the moment step 4 landed. **The durable half (step 7):** the existing floors iterate `model_fields`, so a connection-scoped deviation is outside their reach BY CONSTRUCTION; the new floor censuses the connection FACTORY signatures instead, and was proven red on purpose twice. Reported is not gated โ€” nothing refuses either deviation, and DEPLOYMENT.md's maintenance note now carries that as a standing rule. *(Filed as one item, not two: both are fixed by the same edits to the same four files โ€” a reader beside `accepted_cleartext_hops`, an entry in `security_loosenings()`, an advisory beside `_check_cleartext_accepted`, and threading at `api/app.py`.

All 41 status glyphs are gone, per [`../CLAUDE.md`](../CLAUDE.md) ยง11: a glyph's meaning is positional and invisible to a reader who learns it from examples, and every table here reads identically without one. Most sat beside the word they decorated (`Built`, `Strong`, `shipped`) and were simply deleted, that word carrying the meaning on its own; only two were rewrites โ€” the red circle in Appendix A.2 row 6 became **Failing**, and the Appendix A.3 legend, where the glyph was the subject rather than a decoration, became prose. The pass also edited **five historical rows of this table in place** (0.11, 0.10, 0.9, 0.8, 0.3), so the record itself moved; only the glyphs in them changed. Added **ยง5.1** as the single home for `/simplify`, a local, human-invoked review tool that **applies** its fixes: it is not one of the five measurement gates, sits outside the AI companion ยง6.5 local gate, and carries no **Built** status, because it ships with Claude Code rather than with this project and so leaves no artifact here to score. ยง5.1's out-of-scope list is an open "at least" class: it names the store-backend parity signal 9 already whitelists and the ADR 0030 `tee/anon/` vendoring that signal 9's `messagefoundry/`-scoped scan cannot see, and it carries the defensive branching tolerant HL7 parsing requires as a separate signal 11 (complexity) concern rather than a duplication one. Corrected a **pre-existing** Appendix A.3 error that the glyph pass surfaced rather than introduced: the legend glossed its status marker as *shipped (advisory; PR \#1028 or PR \#1040)* over a five-item list whose item 5 is blocking and shipped under PR \#1047 โ€” that legend is unchanged in every commit this file has existed in, so it long predates this cycle.

That is a failure mode this rubric had no defence against: section 4.1 forbids over-trusting a *number*, but nothing forbade over-trusting a *green check that never ran* โ€” and three defects across two of the five Tier 2 gates turned out to have that shape (two measuring nothing, one publishing a wrong derived number). Section 4.0 now requires every advisory gate to prove it measured something (units **examined**, never units found โ€” a clean repo reports zero and must still pass) or to declare explicitly, with a reason, that it had nothing to measure; and any derived headline figure must be cross-checked against an independently produced measurement of the same quantity. Implemented as the `liveness` job in `quality-advisory.yml` โ€” the only job there permitted to go red โ€” with `tests/test_gate_liveness.py` replaying the historical incidents to prove the check catches them, and the good-news cases to prove it does not fire on them. **The control was itself adversarially reviewed before merge, and the review found it carrying the same weakness it was built to catch, in three places** โ€” a dead coverage gate could pass by claiming "not applicable", an empty mutmut results file reported a flawless score, and the reconciliation sum was algebraically blind to the very count it claimed to protect. All three are fixed and regression-tested; rule 3 above was rewritten because of the third.

Corrections, each measured rather than reasoned: **(a) Signal 7 was scored Built in 0.8 and 0.9 while producing nothing.** `mutmut<3` resolved to 2.5.1, which crashes on Python 3.14 in its pony-ORM cache (`cannot pickle 'itertools.count'`) *before generating a single mutant*; `\|\| true` made the job report success in 37s, so the gate looked green for two versions. Repaired on `mutmut==3.6.0` (+ `pytest-timeout`, and `source_paths` must be the package, not the one file, or the mutant copy cannot import `conftest`). Now genuinely measured: **461 mutants, 87 killed, 19 survived, 3 seconds** โ€” so the "Expensive / never per-PR" cost model in ยง5 was also wrong, and mutation now runs on PRs. **(b) Signal 11's "85 functions over C901>10" is now 122 across 43 files**, and the raw list was found unusable as a diff signal (every finding anchors on one `def` line), so a merge-base delta was added that reports only PR-caused changes. **(c) Signal 8 now emits inline PR annotations** rather than console-only output.

Extend `tests/test_phi_exception_sweep.py` (SEC-46's module) with that arm: (a) after a real `serve` startup, assert `loop.get_exception_handler()` and `sys.excepthook` are the project's, not the interpreter defaults; (b) induce an unhandled exception on **each** path โ€” a fire-and-forget asyncio task and a main-thread raise โ€” whose argument carries a synthetic PHI sentinel; (c) assert the sentinel appears **zero** times in the stdout capture, every `[logging]` file sink, the syslog forwarder stub, the audit row, `/metrics` and a support bundle taken afterwards, while the exception **type** still appears (so the row cannot pass by swallowing the failure). `KeyboardInterrupt` must still reach `sys.__excepthook__` untouched. | | SEC-74 | `netaddr` allow-list parity across its two callers | Negative/Security | pytest | any | n/a | T | P1 | New `tests/test_netaddr_parity.py`. `messagefoundry/netaddr.py` exists to be "the ONE place an IP allow-list decision is made" โ€” its entire value is that its two callers cannot disagree about what an entry means: the inbound connectors' per-connection `source_ip_allowlist` (`peer_ip_allowed`, called from `transports/mllp.py:1419`, `tcp.py:495`, `dicom.py:263`, `http_listener.py:374`) and `[security].allowed_client_networks` (`client_network_allowed`, called from `api/client_networks.py:159`). Drive **one shared table** of (address, allow-list) cases through **both** callers and assert an identical decision per cell: bare IPv4, IPv4 CIDR, bare IPv6, IPv6 CIDR, an IPv4-mapped IPv6 peer (`::ffff:a.b.c.d`) against an IPv4 entry, `/32` and `/128`, a host-bits-set entry (`strict=False`), a malformed entry (skipped defensively), an unresolvable/`None` peer (fail closed), a non-parsing literal such as starlette's `"testclient"` (denied), and an empty/`None` list (permit all). **Exactly one divergence is sanctioned and the test must assert it is the only one:** loopback is unconditionally allowed by `client_network_allowed` (`netaddr.py:95-108`) and is **not** allowed by `peer_ip_allowed`, because an ingest listener allow-listing a partner must never silently also admit the local box. A new divergence in either direction reds the suite.

Feed `load_pkcs12` an adversarial corpus generated in `tmp_path`: wrong passphrase, empty passphrase vs `None`, truncated/garbage DER, a zero-byte file, a bundle with no private key, one with no leaf certificate, a multi-certificate chain with the leaf last, an oversized (>10 MiB) bundle, a deliberately deep chain, and a key algorithm the PEM exporters do not support.
