# Engineering Log — SET50 Alternative Data Platform

## Current status

| Milestone | Status | Evidence | Next action |
|---|---|---|---|
| M0 repo foundation | complete | Flask API, Vue/Vite shell | replace fixture with source adapter |
| Tourism deterministic signal | complete | 7 backend tests pass | add replayable real source |
| Internal paper ledger | complete | POST/readback through live API | persist in PostgreSQL later |
| Dashboard | complete | Vite build + live HTML/API checks | visual browser capture after permission is available |
| LLM analysis | deferred | intentionally no LLM dependency in M0 | add after signal lineage is stable |
| Webhook receiver | deferred | contract only, no external receiver | choose after core app is usable |
| MT5 bridge | deferred | not started | paper bridge after webhook decision |

## Guardrails

- Research and paper modes only.
- No live orders, external webhook receiver, broker credentials, or MT5 connection.
- Deterministic signal is authoritative; LLM will remain downstream.
- Fixture source is clearly marked and must be replaced before investment use.
- `target_weight` is recorded in the internal paper ledger; it is not an order.

## Verification

- Backend: 10 unittest tests pass.
- Independent review: **PASSED**; no concrete security or logic blockers.
- Reviewer suggestions: set `PAPER_COOKIE_SECURE=1` outside local HTTP; replace in-memory sessions before multi-worker deployment.
- Frontend: `npm run build` passes with Vite.
- Backend health endpoint returns HTTP 200 JSON.
- Dashboard served HTML contains the current title, Vue mount point and Vite entry.
- Paper ledger POST and readback work through the live API.
- Browser visual capture was blocked by Chrome remote-debugging permission; no permission dialog was clicked.
