Complete RedFlag codebase with two major security audit implementations.
== A-1: Ed25519 Key Rotation Support ==
Server:
- SignCommand sets SignedAt timestamp and KeyID on every signature
- signing_keys database table (migration 020) for multi-key rotation
- InitializePrimaryKey registers active key at startup
- /api/v1/public-keys endpoint for rotation-aware agents
- SigningKeyQueries for key lifecycle management
Agent:
- Key-ID-aware verification via CheckKeyRotation
- FetchAndCacheAllActiveKeys for rotation pre-caching
- Cache metadata with TTL and staleness fallback
- SecurityLogger events for key rotation and command signing
== A-2: Replay Attack Fixes (F-1 through F-7) ==
F-5 CRITICAL - RetryCommand now signs via signAndCreateCommand
F-1 HIGH - v3 format: "{agent_id}:{cmd_id}:{type}:{hash}:{ts}"
F-7 HIGH - Migration 026: expires_at column with partial index
F-6 HIGH - GetPendingCommands/GetStuckCommands filter by expires_at
F-2 HIGH - Agent-side executedIDs dedup map with cleanup
F-4 HIGH - commandMaxAge reduced from 24h to 4h
F-3 CRITICAL - Old-format commands rejected after 48h via CreatedAt
Verification fixes: migration idempotency (ETHOS #4), log format
compliance (ETHOS #1), stale comments updated.
All 24 tests passing. Docker --no-cache build verified.
See docs/ for full audit reports and deviation log (DEV-001 to DEV-019).
