SW-06: correlate activation, reset and drain replies by source object identity
against the captured waiting worker or controller, so an arbitrary same-origin
source cannot close this page's admission, and end a request immediately as
PROTOCOL_MISMATCH when the source is swapped instead of waiting for the drain
timeout. requestActivation() and resetOwnedCaches() are single-flight, so ten
concurrent callers share one nonce, listener and postMessage.
SW-07: an empty in-scope client set is vacuously drained rather than rejecting
a waiting worker when the requester already closed.
SW-08: isolate per-client postMessage failures. A client that cannot receive the
drain request fails immediately instead of holding pending state to the timeout,
skipWaiting() is the activation commit and its failure is a rejection, and the
accepted and reload notifications are sent afterwards as best effort.
SW-09: fence late install work. A fenced worker starts no new candidate work, a
late response body from a non-cooperative fetch is cancelled, a throwing digest
maps to a closed outcome, and a second exact delete of the owned candidate cache
is registered once the abandoned install settles - without extending the public
60s bound.

SW-URL-01: canonicalize each generated root-relative manifest URL against the
registration scope once, re-check same-origin, and share that absolute identity
across install cache keys, fetch classification and cache lookup or delete.
Previously every verified asset fell through to the network.
SW-01: serve verified static requests only from the current release cache. A
CacheStorage-wide match could return a previous release's response for the same
URL while the delete targeted a cache that was never read. The worker scope
facade no longer exposes a wide match at all.
SW-02: cache reset deletes only names that parse as owned, so a foreign cache
sharing the ca-static-v1- prefix survives.
SW-03: unregister() resolving to false is a FAILED unregister, not UNREGISTERED.
SW-04: staged removal reports what happened - ABSENT, UNREGISTERED and PURGED
map to DISABLED, OWNERSHIP_MISMATCH to INCOMPATIBLE and FAILED to FAILED - so a
later release cannot delete the worker while a registration or owned cache is
still present.
SW-05: add the runtime-neutral service-worker-static-manifest codec that owns
exact row keys, the extension and content-type allowlist, the root-relative URL
rule and the length-prefixed canonical bytes. The generator and the build gate
hash those same bytes, and the build gate now decodes and recomputes the set
digest instead of type-casting the manifest.
