commit f97d4845affb2f018e8be5eca279ed8ca390b25b Author: jpetree331 Date: Sat Mar 28 21:25:47 2026 -0400 feat(security): A-1 Ed25519 key rotation + A-2 replay attack fixes 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).
