feat(ta1): TA1 interchange ACK parser, persistence, and API
Adds full TA1 (Interchange Acknowledgment, X12 envelope-level) support
to mirror the existing 999 transaction-set ACK pipeline.
Parser & models
- parsers/models_ta1.py: Pydantic Ta1Ack + ParseResultTa1 models
(AckCode = Literal['A','E','R'], date serializer mirroring 999)
- parsers/parse_ta1.py: TA1 segment parser
- Tolerant YYMMDD (6-digit) + CCYYMMDD (8-digit) date handling
for CO Medicaid interchange_date / ack_generated_date
- 106-char ISA validation (15-char sender/receiver IDs)
- source_batch_id = 'TA1-<ISA13>'
Persistence
- migrations/0005_create_ta1_acks.sql: ta1_acks table + indexes
on source_batch_id and ack_code
- db.py: Ta1Ack ORM model (flat columns + raw_json, mirrors Ack)
- store.py: add_ta1_ack, list_ta1_acks (returns all rows),
get_ta1_ack
- db version bumped 4 -> 5 (test_acks.py updated)
API (api.py)
- POST /api/parse-ta1: text/file ingest, persists ta1_ack,
returns detail-ready payload
- GET /api/ta1-acks: list with limit + total (mirrors 999 pattern)
- GET /api/ta1-acks/{ack_id}: detail
- _ta1_to_ui / _serialize_ta1 / _serialize_ta1_from_row helpers
Tests (17 new, 508 total passing)
- tests/test_parse_ta1.py (8): CCYYMMDD + YYMMDD acceptance,
E/R codes, source_batch_id, missing ISA/TA1, short defaults
- tests/test_api_ta1.py (9): happy path, rejected persists,
empty/malformed 400, missing file 422, detail regenerates
segment, 404, empty list, newest-first
- tests/test_prodfiles_smoke.py: extended to smoke-test 352
production TA1 files (A=0, R=352, E=0)
- tests/test_api_parse_persists.py: cross-pipeline reconciliation
test asserting invariants across 837P + 835 prod files
Real-data finding: all 352 production TA1s are R (rejected);
operator follow-up warranted.
