Fixes 9 auth middleware findings from the A-3 recon audit.
F-A3-11 CRITICAL: Removed JWT secret from WebAuthMiddleware log output.
Replaced emoji-prefixed fmt.Printf with ETHOS-compliant log.Printf.
No secret values in any log output.
F-A3-7 CRITICAL: Config download now requires WebAuthMiddleware.
GET /downloads/config/:agent_id is admin-only (agents never call it).
F-A3-6 HIGH: Update package download now requires AuthMiddleware.
GET /downloads/updates/:package_id requires valid agent JWT.
F-A3-10 HIGH: Scheduler stats changed from AuthMiddleware to
WebAuthMiddleware. Agent JWTs can no longer view scheduler internals.
F-A3-13 LOW: RequireAdmin() middleware implemented. 7 security settings
routes re-enabled (GET/PUT/POST under /security/settings).
security_settings.go.broken renamed to .go, API mismatches fixed.
F-A3-12 MEDIUM: JWT issuer claims added for token type separation.
Agent tokens: issuer=redflag-agent, Web tokens: issuer=redflag-web.
AuthMiddleware rejects tokens with wrong issuer.
Grace period: tokens with no issuer still accepted (backward compat).
F-A3-2 MEDIUM: /auth/verify now has WebAuthMiddleware applied.
Endpoint returns 200 with valid=true for valid admin tokens.
F-A3-9 MEDIUM: Agent self-unregister (DELETE /:id) now rate-limited
using the same agent_reports rate limiter as other agent routes.
F-A3-14 LOW: CORS origin configurable via REDFLAG_CORS_ORIGIN env var.
Defaults to http://localhost:3000 for development.
Added PATCH method and agent-specific headers to CORS config.
All 27 server tests pass. All 14 agent tests pass. No regressions.
See docs/A3_Fix_Implementation.md and docs/Deviations_Report.md
(DEV-020 through DEV-022).

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).
