Three changes that unblock the daily inbound pull from Gainwell's
FromHPE MFT path:
1. INBOUND_RE now accepts both 'TP' and 'tp' prefixes via inline
(?i:TP) scoping — case-folding the whole pattern would let
lowercase '837p' / tracking IDs through, which is invalid HCPF.
The rest of the pattern is still case-sensitive.
2. _list_inbound_paramiko skips *_warn.txt entries. Gainwell's MFT
drops ~583 advisory text-format notes in the same inbound dir;
they come first alphabetically and were padding every poll with
~80 min of pointless downloads.
3. New SftpClient.list_inbound_names() + download_inbound() pair
gives a metadata-only listing and on-demand fetch. The
scheduler's existing full-listing path still works (now without
the warn padding); the new path is what the new
/api/admin/scheduler/pull-inbound endpoint and the
'cyclone pull-inbound' CLI use to fast-target a date range
without paying the cost of a full ~6000-file download.
Scheduler.process_inbound_files() runs the same per-file pipeline
as a regular tick on the pre-fetched list, so dedup via
processed_inbound_files still applies.
Tests added in test_filenames.py (lowercase + mixed-case cases),
test_sftp_paramiko.py (warn skip + no-download listing), and
test_scheduler.py (process_inbound_files idempotency).
With this, the daily 385-file pull for 20260624 completes in
seconds via 'docker exec cyclone-backend-1 python -m cyclone
pull-inbound --date 20260624 --block dzinesco' (or the equivalent
POST to /api/admin/scheduler/pull-inbound?date=20260624).
The dzinesco SP9 seed had `paths.inbound` and `paths.outbound` mapped to
the wrong Gainwell MFT directories:
- paths.outbound was FromHPE/ (HPE sends files FROM here TO us — inbound)
- paths.inbound was ToHPE/ (we send files TO here — outbound)
So `/api/clearhouse/submit` was writing 837P claims to FromHPE (where
HPE puts acks/835s) and the SP16 scheduler was polling ToHPE (where our
claims go). 999 / TA1 / 835 files in the real FromHPE inbox were
unreachable.
Semantics per operator (2026-06-24):
- FromHPE = HPE/Gainwell → us = 999, TA1, 835 (inbound)
- ToHPE = us → HPE/Gainwell = 837P claims (outbound)
**Runtime code (the actual fix):**
- backend/src/cyclone/store.py — SP9 seed paths flipped
- backend/src/cyclone/edi/filenames.py — docstring corrected
**Test fixtures + assertions (would otherwise fail on the new seed):**
- backend/tests/test_clearhouse_api.py
- backend/tests/test_providers_seed.py
- backend/tests/test_sftp_stub.py — incl. inbound dir paths
- backend/tests/test_sftp_paramiko.py
- backend/tests/test_store_update_clearhouse.py
- backend/tests/test_api_clearhouse_patch.py
- backend/tests/test_scheduler.py
- backend/tests/test_api_scheduler.py
**Docs (text-only — keeps the codebase self-consistent):**
- README.md
- docs/reference/co-medicaid.md
- docs/superpowers/specs/2026-06-20-cyclone-multi-payer-npi-sftp-design.md
**Operator action required after merge:** the existing clearhouse row in
`~/.local/share/cyclone/cyclone.db` was seeded with the old wrong
paths. Easiest recovery:
1. `rm ~/.local/share/cyclone/cyclone.db` and let `ensure_clearhouse_seeded` re-run on next boot, OR
2. PATCH /api/clearhouse with the new `paths` block (the SP25
reconfigure hook picks it up live, including by the running scheduler).
**Verification:**
- 82 tests in the affected files pass (test_clearhouse_api, test_providers_seed,
test_sftp_stub, test_sftp_paramiko, test_store_update_clearhouse,
test_api_clearhouse_patch, test_scheduler, test_api_scheduler, test_filenames).
- Full backend suite: 1029 pass + 36 pre-existing order-dependent flakes
unrelated to this change (verified by running the same tests in isolation).
Adds an asyncio-based background scheduler that polls the Gainwell
MFT inbound path, downloads new files, and routes them through the
appropriate parser (999 / 835 / 277CA / TA1). Idempotent (re-ticks
and restarts skip already-processed files via the new
processed_inbound_files table). Crash-safe (per-file try/except so
one bad file doesn't stop the loop).
Lifespan auto-configures from the seeded dzinesco clearhouse's SFTP
block; auto-start is opt-in via CYCLONE_SCHEDULER_AUTOSTART.
Five admin endpoints added:
GET /api/admin/scheduler/status
POST /api/admin/scheduler/start
POST /api/admin/scheduler/stop
POST /api/admin/scheduler/tick
GET /api/admin/scheduler/processed-files?status=&limit=
20 new tests (15 unit + 5 API).
