The README only documented up to SP8 even though SP9-SP13 (multi-payer
+ multi-NPI + SFTP stub, 277CA + Payer-Rejected lane, tamper-evident
audit log, optional SQLCipher encryption, paramiko SFTP wire-up) are
all merged into main.
This brings the README back in line with the codebase:
- Inbox section: bump lane count from four to five, add the
payer_rejected lane (and its monotonic stamping contract).
- Add a Multi-Payer, Multi-NPI & Clearhouse section (SP9): the
providers / payers / payer_configs / clearhouse tables, the
config/payers.yaml loader, the new config + clearhouse endpoints.
- Add a 277CA Claim Acknowledgment section (SP10): parse-277ca +
277ca-acks, the Payer-Rejected stamp semantics.
- Add a Tamper-Evident Audit Log section (SP11): hash-chained
audit_log, the verify endpoint.
- Add an Encryption at Rest section (SP12): Keychain-stored
SQLCipher key, transparent fallback to plain SQLite.
- Add an SFTP Wire-Up (paramiko) section (SP13): the production
submit path and the file-naming template.
- Persistence section: link to the Encryption at Rest section.
- Roadmap: bump shipped sub-projects to 2-13, add a one-line
pointer to the completeness review for the honest industry-gap
accounting.
- Project layout: add api_helpers, db_crypto, audit_log, the new
inbox_* modules, providers/payers/secrets, the new test files,
and the config/ + docs/reviews/ + docs/superpowers/specs/ tree.
- backend/README: refresh the endpoint table to include the
parse-999/parse-ta1/parse-277ca/eligibility/clearhouse/admin
surface; point at the root README for the full route list.
