The persistence layer for the SP28 join table lands in
cyclone/store/claim_acks.py:
- add_claim_ack — insert + publish 'claim_ack_written' on the bus
(mirrors the publish-from-store pattern used by the ACKs paths)
- list_acks_for_claim / list_claims_for_ack — read helpers for the
two list endpoints
- find_ack_orphans — Inbox ack-orphans lane source: every ack row
whose ack_id has no ClaimAck row tied to it
- remove_claim_ack — unlink + publish 'claim_ack_dropped'
- batch_envelope_index — D10 in-memory map of
{envelope.control_number: batch.id}, called once per ingest (cost
is ~16 lookups today; trivially cheap)
Plus the to_ui_claim_ack serializer in store/ui.py mirroring
to_ui_ack shape — single source of truth for the wire format so the
live-tail event payload matches the list endpoint byte-for-byte.
Includes a single SELECT against claims for the claim_state field
(TA1 batch-level rows return 'n/a').
The CycloneStore facade in store/__init__.py re-exports all six
methods (add_claim_ack, list_acks_for_claim, list_claims_for_ack,
find_ack_orphans, remove_claim_ack, batch_envelope_index) plus
to_ui_claim_ack from the ui module.
Migration-version assertions in test_acks.py and test_db_migrate.py
bumped 17 → 18 to match the new migration head.
Steps 3.1/3.2/3.3/3.4 of the SP28 implementation plan.
