A generation whose request or poll fetch was in flight at a host death counts
one failed attempt of the retry policy (backoff, the partial kept, the same
deferred handle polled again); without retries left the run ends with
runFailure interrupted. restartLimit ends every other task visibly instead of
parking it (tool error result, compactionFailure, runFailure restart_limit,
faulted extension tasks) and reports task_interrupted; retryTask, task_parked
and the restart_limit blocked reason are removed.

The Node driver takes the count from node:sqlite; the Durable Object driver reads
SELECT changes() after the statement, since the cursor's rowsWritten also counts
index writes (verified in workerd). run is unchanged and costs nothing more.
Every built-in storage implements ReplayableStorage: head(), replay() at an explicit sequence, and export() of the current state as a log that replays to the same reads. SQLite schema version 3 adds sequence indexes so export streams. @earendil-works/pi-durable/sync adds ReplicatingStorage, which appends each committed batch to an outbox with fork copies resolved, compactRecords(), and versioned JSON log lines.
- Open counts restarts per task; at settings.restartLimit (default 5) a task is parked as blocked
(restart_limit) until Harness.retryTask().
- onReport(error, info) with ReportInfo: session, task (faulted), extension, listener, host, timer, wake.
Task faults are reported.
- settings.afterFailedRun: keep, continue, or withdraw the inputs queued behind a failed run.
- TaskGraphNode.blocked follows registry changes and failed migrations.
- README: fallback alarm before Harness.open in the Durable Object example.
The README example and the test worker arm the recovery alarm before resume() in the constructor and in
alarm(). Timers should not fire early, and callers recheck; nativeTimer no longer needs a non-null assertion.
Due sleeps are picked up at every scheduling pass, so a pass that drops the timer cannot strand them.
Code mode drops a global's result after the script finished instead of reading an ended invocation's clock.
A foreground timer the host declines falls back to setTimeout; the default timer never fires early; Progress
rechecks its clock; an undelivered onWake is offered again. Spec, README, and tests follow.
Runs the storage conformance suite, the schema migration, an alarm-woken sleep across an eviction, and a
turn recovered through the recovery alarm in workerd via @cloudflare/vitest-plugin (npm run test:workers).
fix(durable): decline background timers in Cloudflare Workers. With nodejs_compat, timers have an unref(),
so the idle-memory timers were armed and a pending one kept a Durable Object from hibernating or being evicted.
