Workspace packages import 'notifkit' which resolves to root dist/index.d.mts. Running build first ensures declaration files exist before workspace typecheck runs.
- Scope root tsconfig to exclude workspace packages and restore declaration resolution
- Align MCP package zod dependency to ^4.6.5 and update record schemas to explicit key/value syntax
- Upgrade ai dependency to ^7.0.118 to restore bundled dist/index.d.ts declarations
- Fix rate limiter inFlightLease promise initialization in TS strict mode
- Add typecheck:workspaces script and wire into CI workflow
- Run k6 inside Docker bridge network to eliminate host networking and Node loop overhead
- Add dual-scenario execution for 45s warm-up and 180s steady-state isolation
- Track custom k6 Trend metrics and parse steady-state latency percentiles
- Support --warmup and --vus CLI flags in test runner
- Buffer concurrent publish and publishBatch calls into a single pipeline flush per event loop tick
- Apply MAXLEN ~ trimming only to the last command in each batch to reduce scan overhead
- Throttle periodic stream length monitoring to once every 5 seconds
- Key in-memory authCache by raw token instead of tokenHash
- Compute SHA-256 only on cache misses when querying database
- Store structured auth record to avoid string splitting and parseInt
- Maintain tokenHash-to-token reverse map for targeted cache invalidations
- Replace per-request synchronous Redis check with ApiRateLimiter in request pipeline
- Replace eager new URL() allocation with indexOf query pathname slice and lazy getters
- Invalidate in-memory rate limiter leases on API key broadcast
- Upgrade zod to ^4.6.5 along with compatible dependency updates across ai, dotenv, drizzle-orm, ioredis, pino, postgres, and dev tools.
- Adjust tests/workers-ai.test.ts mock UUIDs to adhere to RFC 4122 v4 validation in Zod 4.
- Update tests/http.test.ts validation message expectations for Zod 4.
- Replace generic server container names with role-based definitions (api-server-1, api-server-2, enricher-worker, engine-worker, delivery-worker).
- Add serverNodes option in distributed profiling harness to route and health-check designated worker and API nodes.
- Add multi-run statistical metrics (mean, median, min, max, stdDev) reporting to money-scaling benchmark runner.
- Support budget tier arguments with or without leading dollar signs in test:money
- Tune worker concurrency and provider mock latency defaults for scaling tests
- Add two-phase idempotency with acquireLease and markProcessed using a single-key SET NX fast path
- Return { ack: false } on lock collisions to leave messages pending in the stream instead of acknowledging them
- Bound provider dispatch timeout within the lock lease window to prevent duplicate delivery under slow responses
- Replace per-message Redis MULTI/INCR retry keys with Redis Stream PEL delivery counts
- Handle LockHeldError in BaseWorker to skip message acknowledgement when another worker holds the lock
Eliminate dynamic imports on execution hot paths and module startup:
- Import drizzle-orm sql statically in delivery worker
- Import node:crypto and transport registry statically in API handlers
- Import provider SDKs statically in Twilio and FCM packages
- Replace root barrel imports in config and db with direct submodules to prevent circular evaluation
- Update workflow tests to preserve redis mock exports via importOriginal
- Register custom Lua scripts during RedisClient initialization via defineCommand
- Pre-compile checkApiRateLimit, throttleProvider, throttleUser, releaseLock, renewLock, and schedulerPoll
- Augment ioredis Redis and ChainableCommander type interfaces for custom commands
- Maintain eval fallbacks across callers for compatibility with test mocks
- Add test suite in tests/redis.test.ts verifying registration, execution, and fallbacks
- Replace O(N) ZSET with O(1) sliding-window counter across two buckets
- Define LUA_SLIDING_WINDOW_COUNTER at module level to avoid per-request string allocations
- Eliminate crypto randomBytes generation on hot path
- Use Redis hash tags for cluster-safe multi-key evaluation
- Add tests for window weighting, TTL, and limit rejection
- Cap Redis stream retention at 100,000 messages (down from 10,000,000) in
src/config/index.ts and .env.example to prevent unbounded memory growth.
- In src/services/api/handlers.ts, update getSystemMetrics to resolve stream
queue depths using consumer group lag and in-flight pending entries (via
XINFO GROUPS) instead of raw XLEN. This prevents acknowledged and delivered
notifications from persisting as ghost backlog in the dashboard.
- Retain XLEN measurement for DEAD_LETTER queue where messages persist until
replayed or deleted.
- Adjust dashboard capacity scaling to 100,000 items in AnalyticsPage.tsx and
update backpressure warning threshold to 80,000 in DashboardHeader.tsx.
- Ensure 0-depth queues render empty (0% width) in the backlog gauge meter.
- Update queue test expectations in tests/queue.test.ts and add unit tests
verifying consumer group lag resolution in tests/api-admin.test.ts.
- Provide Docker Compose test harness with CPU and memory resource limits\n- Add single-node CPU scaling benchmark suite (0.5 to 4.0 vCPU)\n- Add distributed multi-node scaling and budget benchmarks (, , /mo)\n- Support partitioned service topologies (dedicated API, pipeline worker, and delivery worker instances)\n- Implement configurable provider latency simulation with randomized network jitter\n- Support dynamic client and worker concurrency tuning
- Support latencyMs in ConsoleTransportOptions as a fixed number or range string (e.g. '60-150')\n- Apply randomized jitter between bounds to simulate real-world vendor network response times
- Collapse Enricher and Decision Engine into direct outbound dispatch: Enricher evaluates quiet hours, topic opt-outs, and renders templates in-memory before publishing directly to STREAMS.OUTBOUND_*, eliminating intermediate STREAMS.ENRICHED_* Redis stream hops
- Add transactional direct fast-path in /v1/notify: Critical priority notifications with inline user targets bypass inbound and decision queues, rendering templates from cache and dispatching directly to STREAMS.OUTBOUND_CRITICAL
- Reduce first-delivery latency from 6.2s to 0.38s and increase wall drain throughput by up to 58% on budget infrastructure
- Add unit and integration tests covering Enricher direct outbound dispatch and API transactional fast-path routing
- Implement stream-keyed ACK buffering in StreamConsumer with periodic and capacity-triggered flushes
- Consolidate delivery outbox persistence to a single post-dispatch write, cutting PostgreSQL outbox writes by 50%
- Make retry key deletion and idempotency TTL extension non-blocking on message success
- Add host-unique consumer identifiers across distributed delivery, engine, and enricher workers
- Add unit tests verifying buffered stream ACK flushing behavior
- migrate dashboard from Next.js to Vite SPA with React Router
- install standard shadcn/ui components using shadcn CLI
- use standard shadcn theme with default CSS variables
- handle optional project scoping in system metrics and health handlers
- update admin-static service to serve Vite dist and proxy dev server
