M-Obs 1: Event bus in @shade/core
- ShadeEventEmitter with typed event union, ring buffer for replay
- 12 event types covering session lifecycle, ratchet operations,
prekey changes, identity rotation, trust changes
- Wired into ShadeSessionManager (zero overhead when not enabled)
- shortHash helper for safe display of public keys
- Security test: regex-checks event payloads contain no key material
M-Obs 2: Prekey server event hooks
- PrekeyServerEvents emitter mirroring core's pattern
- 5 server event types: registered, fetched, replenished, deleted, rate_limited
- Wired into all routes including the rate-limit error handler
- shortHash helper using crypto.subtle directly (no provider dep)
M-Obs 3: @shade/observer package
- StateAggregator subscribes to client + server events, builds rolling snapshot
- Hono routes: GET /api/state (snapshot), GET /api/events (SSE stream)
- Bearer token auth via SHADE_OBSERVER_TOKEN, query string for SSE
- Refuses to start with token < 16 chars (ConfigurationError)
- Static file serving for bundled dashboard at /dashboard/
- Placeholder dashboard renders when no built SPA present

M-Hard 6: PostgreSQL Storage Backend
- @shade/storage-postgres with PostgresStorage + PostgresPrekeyStore
- Drizzle-style raw SQL ensureClientTables / ensurePrekeyServerTables
- All tables prefixed `shade_` to avoid collisions in shared databases
- DELETE ... FOR UPDATE SKIP LOCKED for concurrent OTPK consumption
- Tests skip gracefully without SHADE_TEST_PG_URL, run against real PG when set
M-Hard 7: Production Server Infrastructure
- Structured JSON logger (logger.ts) — SHADE_LOG_LEVEL configurable
- Health endpoints (/health, /healthz, /ready) — Kubernetes-friendly
- Prometheus metrics (/metrics) — counters, histograms, middleware
- Graceful shutdown with SIGTERM/SIGINT handlers + store close
- Production Dockerfile with non-root user, healthcheck, multi-stage build
- docker-compose.yml example for Dokploy with optional PostgreSQL

Shade sessions and keys now survive server crashes, container restarts,
and power outages via SQLite with WAL mode.
New packages:
- @shade/storage-sqlite: SQLiteStorage (StorageProvider) + SqlitePrekeyStore
(PrekeyStore), both using bun:sqlite with auto-created tables and WAL mode
- Serialization layer in shade-core for SessionState/keys ↔ JSON/base64
Docker usage: mount volume at /data, set SHADE_DB_PATH=/data/shade-client.db
Prekey server auto-detects SHADE_PREKEY_DB_PATH for SQLite persistence
Includes crash recovery integration test: encrypt → close DB → reopen →
conversation continues seamlessly.
129 tests, 0 failures.
