BT-PRE-02: add the top-level PRESIGNED_TRANSFER_V1 protocol literal to the
capability request and response. A missing, V0 or V2 envelope is closed as
POLICY_REJECTED before the vault registers anything. The server negotiates by
request shape; fields are never dual-emitted into a strict decoder, and the
nested PRESIGNED_MULTIPART_V1 binding protocol is unchanged.
BT-PRE-03: aborting a controller does not settle a fetch that ignores its
signal, so both presigned scopes now race the task, cancel a late response body
and survive a throwing scheduler without leaking the external abort listener.
BT-PRE-04: the vault owns its registration invariants, re-checking method,
href/origin/path agreement, embedded credentials, byte bounds, digest shape and
expiry, so a second issuer cannot register a weaker capability of the same type.
BT-PRE-05: decode each path segment once and require it to round-trip through
the canonical uppercase percent encoder, closing %2f, %5c, %252e%252e, mixed-case
escapes and encoded NUL while still admitting valid opaque UTF-8 segments.
BT-UP-02: inject and snapshot the upload transport clock and scheduler, so
Retry-After delta-seconds and HTTP-date resolve against the same captured now
and a clock rollback clamps to zero instead of producing a negative delay.
BT-IMG-01: make the image resolve() lifetime signal required, replacing the
hidden PRIMARY_REQUIRED preset precondition with a type-level one, and add the
negative typecheck fixture and gate that prove it.

BT-X-01: add the shared abortable-operation utility with golden tests for first
terminal owner, idempotent close, listener and timer cleanup under a throwing
scheduler, observed late rejection and late-handle compensation. It carries no
subsystem result taxonomy.
BT-PRE-01: make the presigned download lease lazy and single-start. open() now
validates, claims and consumes the capability without any network I/O; the
fetch, the transfer deadline and the expiry recheck happen at first stream
consumption. The source gained close(), which discards an unused lease with no
I/O and otherwise cancels the body and releases the scope exactly once.
BT-UP-01: require removeEventListener in the AbortSignal structural guard and
isolate release cleanup so a hostile facade cannot replace a typed terminal
result with a rejection.
BT-UP-03: deleteDatabase cannot be cancelled after dispatch, so a blocked
deadline now returns PENDING with effect UNKNOWN instead of a failure that reads
as NOT_APPLIED. A realm-scoped (factory, databaseName) registry prevents
recreating the partition until the native request settles.
BT-UP-04: reject non-finite and negative upload clocks as a dependency failure
instead of letting them bypass every capability expiry comparison.
BT-IMG-02: replace the naive Cache-Control quote stripping with a quote- and
escape-aware tokenizer, so max-age="60 or 60" is no longer read as 60 and a
comma inside a quoted extension is not a directive boundary.
