## Phase 9D continuation — deferred applicability / notice tooling — 2026-09-16
- Initial Git clean. `tools/security_overrides.py` now requires exact ssh-userauth service, exact bounded CHANNEL_FAILURE recipient with existing fatal policy, and length-first exact names for all nine channel requests. Supported bodies and unknown-request ACK/consumption retained. No ordering/crypto/version changes. `docs/ssh_parser_remaining_review.md` closes finite PR899/902/918/919 and generic current signature caller trace: client key-skip functions remain unpatched but blocked by current server ordering; forwarding absent; no current short-digest/OID trigger found. Not exhaustive parser certification.
- `docs/idf_security_review.md` adds six named advisory dispositions with original/generated/config evidence: ECDH callers sized safely, driver-only PK path excluded, no untrusted CA promotion, privileged-local ECC sidechannel excluded not fixed, server tickets off despite compiled support, fixed CN avoids ASN zero-length replacement. No additional current-path source fix established; generic library defects remain explicitly recorded.
- `tools/release_notices.py` + `third_party/release-notices/inputs.json` assemble62 exact hash-pinned allowlisted notice inputs offline into fresh explicit output, descriptor no-follow traversal, bounded preflight, exclusive creates/no overwrite, deterministic names/bytes. No secret scanning/full repo/config/build collection. Tests30PASS; agent+independent reviewer verified two actual deterministic bundles and hashes. Historical64files541147bytes not general future promise. `docs/release_packaging.md` separates notices from source/recipient/legal obligations. No distribution clearance: radio source exception question, wolf package discrepancy, exact icon provenance and recipient delivery remain open.
- Parent `pio run` PASS **94,340 B linked RAM / 1,768,901 B flash** (+200flash). Parent seven suites PASS: parser3,258x2 plus channel production2,737x2 and fouralternate profiles, 11parser+18name+2appgate mutations; release notices30; auth135; protocol; strict crypto; SDK actual8C+header registration; ordering8,028/7mutations and12OpenSSH sessions each256KiB exact with rekey/cleancloseEOF. Independent review no actionable scoped defects, reran parser/notices and actual bundle determinism. Host evidence not hardware/resource/signoff.
- README/roadmap/hardening/wolf/license/code map integrated latest evidence and finite closure. **Next:** use hardeningdoc remaining implementation/maintenance, release/source/delivery and whole-phase target gates rather than repeatedly reopening completed finite reviews. Broader advisory coverage/unpatched unused primitives not certified; release packaging does not solve legal/source/provenance questions. User whole-phase validation remains deferred; secureboot/encryptedNVS excluded. No device/asset regeneration/dependency upgrade/commit.
## Phase 9D continuation — restricted SSH ordering correction — 2026-09-16
- Initial Git status clean. Implemented restricted-profile CVE-2025-14942 correction without upgrading managed pins. `tools/wolfssh_order/` archives exact PR793/819/840/855/921 bytes, hashes/commits, authoritative consolidated delta and scope. Generator now replaces eight C sources plus one internal header. PUBLIC forced overlay and stale-header marker preserve ABI across all consumers; joined `-include/path` avoids PlatformIO argument sorting/dedup failure.
