From 2dfe213af038493acabbe5893b5addc46ae88e92 Mon Sep 17 00:00:00 2001 From: Nora Date: Tue, 7 Jul 2026 22:33:42 -0600 Subject: [PATCH 01/13] feat(sp41): wire claim-id dedup into submit_file pre-flight MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Inserts a per-claim-id check_duplicate() walk into submit_file between the payer-mismatch guard and the BatchRecord837 DB write (Task 9). If any CLM01 in the parsed 837P file was submitted within the 30-day window recorded in the submission_dedup table, submit_file raises DuplicateClaimError before any DB write or SFTP upload. The DB-first, upload-second invariant is preserved: a duplicate blocks both the BatchRecord837 write AND the paramiko upload. The api_routers/submission.submit_batch per-file loop special-cases DuplicateClaimError BEFORE the generic Exception handler so the 200-with-results status-code contract documented at the top of the module is preserved (per-file failures stay in the body). The exception remains 409-class by design — a future caller that propagates it past the per-file loop will surface 409 at the FastAPI layer. Approach A per the Task 9 spec (raise, don't return a SubmitResult). Tests: - test_submission_dedup.test_submit_file_raises_on_duplicate_claim_id pre-populates the dedup table via record_submission('CLM001', ...), calls submit_file against minimal_837p.txt, expects DuplicateClaimError with structured claim_id / original_submission_at attributes, and pins the DB-write invariant (no Batch row landed) plus an AssertionError sentinel on the SFTP factory. --- backend/src/cyclone/api_routers/submission.py | 27 ++++++ backend/src/cyclone/submission/core.py | 23 +++++ backend/tests/test_submission_dedup.py | 84 ++++++++++++++++++- 3 files changed, 133 insertions(+), 1 deletion(-) diff --git a/backend/src/cyclone/api_routers/submission.py b/backend/src/cyclone/api_routers/submission.py index de208fd..2b6f530 100644 --- a/backend/src/cyclone/api_routers/submission.py +++ b/backend/src/cyclone/api_routers/submission.py @@ -33,6 +33,7 @@ from pydantic import BaseModel, ConfigDict, Field from cyclone.auth.deps import matrix_gate from cyclone.store import store as cycl_store +from cyclone.store.exceptions import DuplicateClaimError from cyclone.submission.core import submit_file from cyclone.submission.result import SubmitOutcome, SubmitResult @@ -154,6 +155,32 @@ def submit_batch(body: SubmitBatchRequest): # monkey-patch submit_file itself instead of wiring a # factory here. ) + except DuplicateClaimError as exc: + # SP41 Task 9: 409-class domain exception (see the exception + # docstring on ``DuplicateClaimError``).

Pipeline A: build a ClaimOutput adapter from the canonical RebillClaim fields (claim_id/member_id/procedure/svc_date/charge) — the per-claim envelope context (provider NPI, subscriber name, payer name) comes from the original claim being replaced and isn't carried forward by the rebill pipeline, so the adapter emits safe placeholders and lets the SP40 serializer fallbacks fill PER / SBR09. Then serialize_837 → cyclone.edifabric.validate_edi → write to pipeline-a/ on success or quarantine/ on Status=='error'. Pipeline B: serialize_member_week_batch(b, tpid=tpid) (the Task 14 overload — takes a MemberWeekBatch, not a ClaimOutput) → cyclone.edifabric.validate_edi → write to pipeline-b/ or quarantine/. Filename disambiguation: build_outbound_filename embeds a millisecond timestamp; multiple files emitted in the same millisecond would collide. Append per-claim / per-batch suffix so the audit trail (claim_id ↔ file / batch_key ↔ file) stays one-to-one. Edifabric unavailability (no API key, network error, 5xx) fails OPEN with a WARNING log: the file lands in the pipeline dir, matches the SP40 dev/CI posture for boxes without a paid key. Quarantine only on Edifabric Status=='error'. New tests in backend/tests/test_rebill_run.py cover: real 837P file emission (non-empty, ISA..IEA envelope) for both pipelines, quarantine on Edifabric error, fail-open on Edifabric unavailability, HCPF-spec filename prefix preserved, per-claim / per-batch disambiguation suffix present, original claim_id preserved in Pipeline A CLM01. --- backend/src/cyclone/rebill/run.py | 202 +++++++++++++++--- backend/tests/test_rebill_run.py | 328 ++++++++++++++++++++++++++++++ 2 files changed, 505 insertions(+), 25 deletions(-) create mode 100644 backend/tests/test_rebill_run.py diff --git a/backend/src/cyclone/rebill/run.py b/backend/src/cyclone/rebill/run.py index beef89d..b8bb638 100644 --- a/backend/src/cyclone/rebill/run.py +++ b/backend/src/cyclone/rebill/run.py @@ -9,11 +9,14 @@ paths from --visits / --ingest / --out; HTTP endpoint passes the same. from __future__ import annotations import csv as _csv +import logging from dataclasses import dataclass from datetime import date, datetime from decimal import Decimal from pathlib import Path +from cyclone import edifabric as _edifabric +from cyclone.edi.filenames import build_outbound_filename from cyclone.rebill.carc_filter import CarcDecision, decide_carc from cyclone.rebill.parse_835_svc import SvcRow, parse_835_svc from cyclone.rebill.pipeline_a import RebillClaim @@ -33,6 +36,8 @@ from cyclone.rebill.summary import ( ) from cyclone.rebill.timely_filing import timely_filing_decision +_log = logging.getLogger(__name__) + @dataclass class RunResult: @@ -78,14 +83,17 @@ def run_rebill( - NOT_IN_835 + past-window → EXCLUDED_TIMELY_FILING (no override) - DENIED/PARTIAL + EXCLUDED CARC → EXCLUDED_CARC - DENIED/PARTIAL + REVIEW/REBILL → Pipeline A (REBILLED_A) - 5.
