#303 is stacked on #299: this branch now carries main (wai.live.compose, #296) and wai.live.recording. The same lines conflict as in #299's merge: SPEC §5's live-records list and paragraphs, REGISTRY's list, wire table and magics, the registry's capability constants, statuses and wire rows, Cargo features, binaries and tests, the module list, the live-conformance README, the int_kernels_vectors reason and the independent-verifiers job. All are kept, compose, recording, then timed text; the three CI steps stay separate. Co-Authored-By: Claude Opus 5.5 <[email protected]>

Merge origin/main into wai/live-record; live-compose and live-recording side by side
Main gained wai.live.compose (#296), which edits the same lines: SPEC §5's live-records list and its paragraph, REGISTRY's list, wire-identifier table and magics, the registry's capability constants, statuses and wire rows, Cargo features, binaries and tests, the module list, the live-conformance README, the int_kernels_vectors reason and the independent-verifiers job. Both are kept, compose before recording; the two CI steps stay separate. capabilities.json is regenerated by wai registry export. Co-Authored-By: Claude Opus 5.5 <[email protected]>

wai: a recording's signer holds the record power at every instant of its span
A principal other than the room authority may sign WRM1 only under a grant with the record power in effect over the whole span: effective at or before its start, with no leave, grant_exchange or expiry taking the power away before its end. A refusal keeps the code recording_signer_not_permitted and states the first instant of the span without the power, at ["signer", t]. Since a recording holds the room's chains whole, the span now binds the takes the package holds (each start and closing commitment within it) and the takes complete counts, not every context record, so a recorder that gained the power partway seals a span that starts at its grant. New vectors: late_recorder_span (stands), signer_power_late, signer_removed, signer_power_exchanged, signer_grant_expired and signer_grant_revoked (refused at the room: a key-log revocation is not bounded by a time).

wai: recordings corpus — a session with a composite component, and its digest mismatch

Co-Authored-By: Claude Opus 5.5 <[email protected]>
wai: wai.live.recording in the registry, SPEC §5, CI and CHANGELOG; the corpus regenerated with region
The registry lists the record and its magics WRM1 (§4.1) and WCL1 (§5.1); the independent-verifiers job runs the module's tests, tests/live_record.rs and live_record_verify.py; the workflow's path lists name the extension; int_kernels_vectors' live-conformance exclusion names recordings and clips. live-conformance/recordings is regenerated from its seeds with the manifest's region and the outside_region vector. Co-Authored-By: Claude Opus 5.5 <[email protected]>
wai: a recording manifest states where the package is kept, held to the room's region pin
live-rooms §3.7 said the recording extension checks a recording's storage against the pin; WRM1 now carries region and the verifier refuses one outside it (store_outside_region). live-events §8.6, live-rooms §3.7 and capture-binding §1 point at live-recording.
