-Signal is a B2B CGM documentation readiness tracker for DMEPOS suppliers.
+Signal is a B2B DMEPOS documentation readiness tracker for CGM suppliers.
 It ingests order data from any DME order management CSV export (e.g., Brightree),
 evaluates each patient against documentation requirements (6-month qualifying
-visit, PECOS enrollment, SWO, resupply eligibility), and produces a Signal Report
-so supplier staff can prioritize outreach and capture revenue before it leaks.

-## Level 1 Stack (Active)
-- Hosting: Hostinger VPS (self-hosted, data never leaves VPS)
-- Language: Python (FastAPI or Flask)
-- Database: PostgreSQL (encrypted at rest, audit logs)
-- Orchestration: n8n self-hosted (24-hr batch trigger)
-- Notifications: Self-hosted Mailcow — encrypted email to DME staff only
-- Frontend: Simple dashboard (Vercel or self-hosted)
-- Auth: Session tokens in PostgreSQL (no Convex needed for MVP)
+## Current Stack (Updated 2026-05-29)
+- Backend: Railway (Python/FastAPI) — live at https://signal-api-production-91c2.up.railway.app
+- Database: Supabase (PostgreSQL + RLS policies + Third Party Auth with Clerk)
+- Auth: Clerk — app name: eternal-goblin-1, domain: eternal-goblin-1.clerk.accounts.dev
+- Frontend: Vite/React (signal-ui) — local dev only at localhost:5173, NOT YET deployed publicly
+- Orgs in Clerk: STTIL Solutions (default), Gaboro DME (org_3EPAEcAw06V2yGMSkxE3UjqIA3c)

+## Run Commands
+- Frontend (local): `cd signal-ui && pnpm dev` → localhost:5173
+- Backend deploy (code change): `railway up --detach` from project root — forces fresh build

+## Known Bugs — Fix Before Pilot
+1. ~~**Payer matching**~~ — FIXED 2026-05-29. `_normalize_payer()` added to `coverage_calculator.py`. Handles: "Medicare Part B" → medicare, "Tricare for Life" / "TFL" → medicare, "Medicaid - GA" → medicaid, commercial insurer names → commercial.
+2. **Visit date**: coverage_calculator.py uses shipment_date as proxy for qualifying visit, not an actual visit date. Fix: use stored confirmed visit date when available; fall back to shipment_date - 30 days labeled as estimated.
 
-## Workload Impact Model (Build This)
-Two-curve graph showing supplier staff time over months:
-- Curve A: Appeals/denials workload (reactive) — starts HIGH, trends DOWN
-- Curve B: Proactive outreach via Signal — starts MANAGEABLE, stays FLAT
-- X-axis: Months 1–12 post-onboarding
-- Crossover point = ROI moment to show on discovery calls
+## Features Not Yet Built — Pilot Priority
+- **Confirm Visit workflow**: staff button on each worklist row to record a confirmed visit date. Signal stores it against patient_id in Supabase. This is Signal's core persistent value — without it, visit dates never improve beyond estimates.
+- **Frontend public URL**: DEPLOYED 2026-05-29 — https://signal-ui-xi.vercel.app
+- **25 CSV variant test suite**: whitepaper requirement. Generate and test 25 mock CSVs with different column orders, headers, date formats, and payer name variants.
+- **Mapping review interface**: confidence score display, user override dropdown per column (per whitepaper spec).

-| Item | Phase | Reason deferred |
-|------|-------|----------------|
-| AWS infrastructure (any service) | Post-pilot | Jakub (coach, 2026-05-28): mock data is sufficient for demos and pilots. AWS takes 2 hours to set up — do it right before signing live PHI contracts. Do not start during MVP or pilot phase. |
-| Dexcom OAuth API integration | Phase 2 | Requires vendor agreement + PHI scope expansion |
-| Billing system API integration (Brightree, Bonafide, Fastrack, etc.) | Phase 2 | Build after pilot reveals which systems suppliers use; vendor agreements required; PHI scope expands significantly |
-| CMS and contact management integration (Salesforce, etc.) | Phase 2 | Pilot feedback will reveal if suppliers have CMS and what they use; do not assume |
-| Prescriber fax automation | Phase 2 | Workflow complexity; Level 1 manual outreach sufficient |
-| Patient-facing SMS (Twilio, not SignalWire) | Phase 3 | PHI transmission to third-party; requires BAA + consent layer |
-| Consortium strategy (Level 2/3) | 18–24 months | Depends on 15+ paying Level 1 suppliers first |
-| Convex | Phase 2+ | Not needed until real-time sync requirements emerge |

+| Demo login / controlled access working | PASS |
+| Synthetic sample data loads end to end | NOT VERIFIED as Gaboro org |
+| 25 CSV variants pass ingestion tests | NOT DONE |
+| Import flow: mapping, validation, warnings | PARTIAL — CSVImport exists, full mapping review unconfirmed |
+| Report generation calculates from backend | PASS |
+| Each status has reason + recommended action | PARTIAL — payer bug fixed; visit date still uses shipment proxy |
+| Export CSV works and opens cleanly | NOT VERIFIED end to end |
+| Placeholder content removed | NOT VERIFIED |
+| Browser smoke test passes | NOT RUN |
+| Data handling rules documented | PASS |
+| Real PHI blocked | PASS |
+| Pilot success metrics written down | PASS |

 ## Instructions for Claude Code Sessions
-- Work only on Level 1 scope
+- Work only on pilot-scope items from the checklist above
 - Never suggest adding PHI fields beyond patient_id
 - Flag any vendor integration that would require a new BAA
 - When building calculations, reference payer_rules.json for wear days
 - When building audit logs, always hash patient_id before storing
-- If asked about Phase 2/3, acknowledge and defer — do not spec or build
-- Use "resupply" not "refill". CGM supply allowances are exempt from Medicare refill rules
+- Use "resupply" not "refill" — CGM supply allowances are exempt from Medicare refill rules
+- Always calculate progress against the whitepaper checklist table above — not subjective feel
+- Before quoting any % complete to Kisa, count the PASS items in the checklist
