Nueva regla del operador (2026-10-31): los ficheros de secretos solo se
inspeccionan con herramientas que no muestran valores (jq keys, grep -c,
stat). Prohibido cat/grep -r sobre .env y volcar errores con DSN.
- tests/test_no_credential_patterns.py: 3 tests — DSN con credencial
literal fuera de placeholders, nsec bech32 versionado, tokens hex de
64 chars fuera de tests/.
- scripts/check-credential-leaks.sh: hook que falla si journald
reciente contiene DSN con contraseña o nsec (redactando el valor en
la salida). Sin timer propio (no autorizado); ejecutar manual o desde
cron del operador.
Contexto: la rotación del rol hardcap y el DSN filtrado a journald por
el test del gate (corregido; la credencial filtrada ya está rotada).
Critical 1 (approval forgery): audit_log is now hash-chained
(prev_hash/entry_hash, verify_audit_chain); executor approve REQUIRES a
BIP-340 signature over sha256(cayce-ops:approve:<id>) when
CAYCE_OPS_OPERATOR_PUBKEY is set; deploy/roles.sql ships least-privilege
per-daemon DB roles.
Critical 2 (threading dead): sends create real OUTBOUND rows (own
Message-ID, In-Reply-To -> inbound); inbound message_id never overwritten;
maild compose adds the first-contact path; _match_proposal falls back to
inbound chains.
Critical 3 (duplicate sends): per-message transactions in send path —
SMTP failure on message N no longer resurrects 1..N-1; failures audited
(send_failed) and the row stays queued.
Critical 4 (classifier): negated approvals (cannot accept / not approved /
not accepting) classify REJECTION at 0.95 before the bare-keyword rule;
LLM prompt braces escaped (.format no longer KeyError into silent fallback).
Critical 5 (systemd): every daemon has a run subcommand
(maild run = poll+send, publisher run = publish-due, monitor run = build);
deploy README documents the separate daily publisher plan timer.
Mediums: approved_hash binds drafts/captions to the approved text (edited
text refuses to send/publish until re-approved); risk_score renamed
match_score (migration 0002) and auto-approve orders HIGHEST relevance
first; compose binds postgres to 127.0.0.1; IMAP marks \\Seen only after
commit (fetch returns (num, raw), mark post-commit); disabled channels are
terminal (ContentStatus.SKIPPED) and publish failures burn a bounded
attempt budget before abandonment; make hooks installs the pre-push gate.
tests: 12 new — 56 total, all green; ruff 0 findings; gitleaks clean.
