R-04: install the RPC contract bindings as exact immutable snapshots. Registry
and row data are copied from own data descriptors into frozen null-prototype
maps before validation, so a getter is never invoked, extra and symbol keys and
malformed descriptors are composition-time TypeErrors, and the runtime reads
only the snapshot. A post-validation mutation can no longer change replay
policy, deadlines, byte ceilings or transport selection.
R-01: bound transport stream cleanup. The generation is fenced and listeners
released immediately, and iterator.return() is awaited only within a cleanup
bound, so a non-cooperative iterator cannot keep the application generator, its
listeners or the total deadline alive. Unresolved cleanup stays observed.
R-05: reject oversized WebSocket text frames before allocating an encoded copy
and count UTF-8 bytes incrementally with an early exit, matching TextEncoder for
surrogate pairs and lone surrogates.
R-06: canonicalise clock and generation-fence failures into the closed Result
taxonomy instead of letting them escape as native rejections, with listener and
timer cleanup on every exit path.
Browser RPC remains AVAILABLE_NOT_COMPOSED; R-07 transport evidence is still
required before composition.

R-02: add an OPEN/DRAINING/CLOSED lifecycle orthogonal to freshness. Effect and
recovery authorities are now awaited under a deadline: on expiry the commit
capability is revoked and the work aborted, the caller gets a bounded
non-retryable IDLE_TIMEOUT, and the underlying task is retained rather than
dropped. A draining stream refuses new events and recovery, and close() returns
a Promise that succeeds only once every retained task actually settled,
reporting IDLE_TIMEOUT otherwise.
R-03: a handoff fail-close moves active, probe, quiescing and transition leases
into a retired-writer set before clearing their references, and close() waits on
current and retired writers together, so an abandoned non-cooperative writer can
no longer make teardown report a false success.

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.
