Engineering Log — SET50 Alternative Data Platform

Current status

Milestone	Status	Evidence	Next action
M0 repo foundation	complete	Flask API, Vue/Vite shell	keep research/paper guardrails
M1 BOT Tourism adapter	complete	18 tests, live BOT fetch, raw/snapshot persistence	validate multiple vintages
Tourism deterministic signal	complete	live foreign-arrivals YoY surprise	add occupancy/airport metric
Internal paper ledger	complete	POST/readback through live API	persist in PostgreSQL later
Dashboard	complete	Vite build + served source check with live-sign copy	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

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 and provisional BOT sources are explicitly labelled; neither is investment-ready without validation.
target_weight is recorded in the internal paper ledger; it is not an order.

Backend: 18 unittest tests pass.
Independent M1 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.
M1 reviewer backlog: add schema-drift, duplicate/reordered-row, and malformed-vintage regression fixtures.
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.
BOT source live fetch parsed 138 monthly periods and persisted raw HTML plus normalized snapshot.
Data-health reports source_mode=bot, status=provisional, and replayable=true.
Live vintage replay returned the same theme surprise as the current dashboard summary.
Browser visual capture was blocked by Chrome remote-debugging permission; no permission dialog was clicked.
