v0.0.2 — 2026-05-06

Hardening release — 19 crash-safety, consistency, and correctness fixes across Queue, Worker, Webhook, Scheduler, and Manager engines.

Fix	Impact
Container `claimBlocking` forwarding	Prevents CPU-burning polling when broker supports blocking claims
Stall handler cleanup	Zombie jobs no longer consume permanent concurrency slots
Worker stall filter	Jobs with failed lock renewals are now properly recovered
Batch cancellation check	Cancelled batch jobs can no longer race to "completed" status

Fix	Impact
Webhook held-job release	`resumeDispatcher()` now releases `"hold"` jobs accumulated while paused
Queue resume dependency check	Held jobs with unmet `dependsOn` deps route to `"waiting-children"`, not `"waiting"`
Manager loop safety cap	Held-job release loop capped at 2000 jobs to prevent infinite loops
Retry/rerun priority passthrough	`retryJob()` and `rerunJob()` preserve `opts.priority` through to the broker

Fix	Impact
Retry `runAt` timestamp	Delayed retries now set `job.runAt` — visible in dashboards and reconciliation
Default priority persistence	Queue-level `config.priority` is persisted on `job.opts.priority` at creation time
Cancel writes tombstone	`cancelJob()` writes a `"cancelled"` status instead of deleting — full audit trail
Schedule `run-all` missed fire	`missedFire: "run-all"` now enumerates all missed occurrences, not just one
Cron type stamp	Prevents namespace corruption in multi-module manager lookups

logger: false now correctly disables all logging (was inverted)
stop() timeout no longer leaks — handle is .unref()'d and cleared
Signal handler binding — SIGINT/SIGTERM handlers now bind correctly
Webhook cancel aborts HTTP — cancellation immediately aborts in-flight delivery requests
MemoryStore falsey values — get() correctly returns 0, false, "" instead of null
MemoryBroker extendLock — O(1) direct lookup instead of O(n) scan
Redis claimBlocking pause re-check — items returned during pause are pushed back
UI auth validation — partial auth config (only username or only password) is now rejected
Webhook resend — clears runAt and opts.delay for immediate re-dispatch

OqronKit launches with 12 enterprise modules for background computation:

Task Queue — Unified monolithic queue
Distributed Worker — Decoupled publisher/consumer architecture
Scheduler — Cron expressions, intervals, recurring schedules, and RRule support
Rate Limiter — Sliding-window and token-bucket algorithms
Webhook — Fan-out dispatch with HMAC signing and circuit breakers
Batch — Accumulator buffering with maxSize / maxWaitMs
Workflow (DAG) — Complex dependency grids with dependsOn
Saga — Distributed transactions with compensation chains
Pipeline — Streaming ETL with backpressure
PubSub — Durable topics and fan-out consumer groups
Cache — Stampede-protected hierarchical memory tiers
Ingest — Event-driven step functions (step.run, step.sleep, step.invoke)
