From 9857ed1424e16fbc462d7da3ea1a4548589237bb Mon Sep 17 00:00:00 2001 From: tegwick Date: Fri, 15 May 2026 15:53:10 +0200 Subject: [PATCH] feat(warden): implement WARDEN-WP-0002 correctness and operational completeness MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit T1 — TTL max enforcement: - models.py: MAX_TTL_HOURS policy constant - ca.py: _enforce_ttl() raises CAError when spec.ttl_hours > type max - Called at top of LocalCA.sign() and VaultCA.sign() - scorecard.py: check_ttl_policy() — flags certs with issued TTL > type max - run_scorecard() now returns 5 checks T2 — Stale cert cleanup: - ca.py: _evict_cert() removes existing cert before writing new one (no accumulation) - cli.py: warden cleanup [actor] [--dry-run] command - check_no_stale_certs detail suggests 'warden cleanup' when stale certs found T3 — Outgoing signatures log: - ca.py: _append_signature_log() writes JSONL to state_dir/signatures.log - Called after every successful sign() in LocalCA and VaultCA - cli.py: warden log [actor] [--last N] [--json] command - parse_cert_metadata now also returns valid_from (needed for TTL policy check) 61 tests passing, ruff clean.
