N-05: the conditional-validator key was a colon join over components that may
themselves contain colons, so two distinct valid bindings could collide and one
definition's ETag could be prepared for another. The key is now a validated,
byte-bounded fixed tuple encoded with JSON.stringify.
N-09: capture localStorage exactly once and compare StorageEvent.storageArea
against that object identity, so a pulse from sessionStorage or any other area
is rejected instead of matching on key and value alone. The pulse key is
registered in the storage registry as CACHE_INVALIDATION_PULSE.
N-10: race loadPage against the caller signal and re-check before observing a
page, so a non-cooperative loader can neither hold loadAll forever nor have a
post-abort completion accumulated into a successful result.

STO-03: reject at composition any policy that enables Vary variants while
stripping vary from the stored response allowlist, since every stored variant
would collide on the same cache key.
STO-04: extract one verifyReleaseCandidate authority shared by the stage fast
path and activation. A matching release marker is a claim, not evidence, so a
restage now re-verifies each entry, deletes only the owned candidate on a
mismatch and refetches. Abort or an unreadable candidate is never stage success
and never moves the active pointer.
STO-05: split the availability guard. Staging keeps the fetcher requirement
with ONLINE_ONLY recovery; activation, rollback and cleanup need only cache
storage and the mutation lock, so an offline rollback or quota-recovery cleanup
is no longer reported UNSUPPORTED.

Replace the boolean browser-managed target validator with
resolveBrowserManagedTarget, which returns the parsed canonical absolute URL,
and hand that exact value to the host. Previously the raw href was passed on,
so a relative target was re-resolved against document.baseURI and a hostile
<base> could send the navigation to an origin the policy never approved.
STO-08 stays UNVERIFIED: the capability spec does not exercise the system
picker, so the receiver-binding hypothesis is neither reproduced nor refuted
and no source change was made for it.

Repair the compensating half of the OPFS put saga.
The coordinator now owns a single abortPreparedPut() driven by a
composition-owned bounded signal instead of the caller's already aborted one,
and the worker client no longer issues a duplicate fire-and-forget abort.
Journal rows and budget reservations are released only after the physical
effect is confirmed CLEANED or ALREADY_CLEAN; a timeout, malformed response or
EFFECT_UNKNOWN keeps PREPARING/FILES_READY and returns OBJECT_RECONCILE.
New writes carry a transaction-unique physicalGenerationId through the staging
receipt, manifest path and prepared object, so a late compensation deletes only
its own transaction's directory even when a newer transaction legitimately
reuses the same logical generation. v1 paths, receipts and prepared objects stay
readable through the rollback window.
Abort and cleanup hold the origin mutation lease through physical deletion and
staging removal. A transaction that never reached staging returns ALREADY_CLEAN
without waiting for the lease, which would otherwise deadlock against the BEGIN
it is cancelling.

Give the best-effort telemetry adapter a terminal ACTIVE/DISPOSED lifecycle.
dispose() now removes the pagehide listener, clears the queue, invalidates
scheduled callback generations and aborts the in-flight sink; emit after
dispose is a no-op and a sink that ignores the abort cannot reschedule or
update post-dispose state. flush() joins the active delivery instead of
resolving early, and runtime infrastructure teardown disposes telemetry first.
Telemetry and diagnostics capacities are validated at construction against a
documented ceiling, so NaN or Infinity can no longer disable eviction.

Separate per-attempt physical state from the logical execution history. The
executor now keeps one monotonic certainty accumulator joined through
joinMutationEffectCertainty, records MAYBE_APPLIED at dispatch, and reads the
accumulator from every retry-loop fence, final-invariant, cancellation and
timeout return.
A retry-time scope fence landing between the loop-entry check and the
pre-dispatch invariant can no longer downgrade an already dispatched command to
NOT_STARTED.

Install the REST auth profile registry once at composition and make it the
single transport authority for V3. Contract composition now rejects an
unregistered authProfileId, so the executor never resolves a profile at
runtime.
The credential collaborator contributes proof headers only: Fetch credentials
come from the resolved profile, transport-owned and forbidden headers are
rejected, headers outside the profile's allowed set are rejected, and a missing
required header fails closed as AUTH_INTEGRATION_FAILURE with zero fetch calls.
The final invariant re-proves credentials mode and the exact header sets.
Demo mode satisfies the strict bearer profile with a fixed non-secret marker
instead of weakening REFERENCE_EXTERNAL_BEARER. Credential owners now receive
the operation lifetime through AuthOperationContext.

Project one typed HttpExecutionObservation per logical V3 execution through a
closed composition-root projector: only registered diagnostic context keys and
bucketed values reach the sinks, and terminal non-abort failures now emit
exactly one api.request.failed telemetry event. Caller cancellation and scope
fencing record a diagnostic but never a failure event.
routeId becomes a required input at the installed operation-executor boundary
so the feature gateway's low-cardinality route identity survives to the sink.
