EP051 · local-to-hosted data sync

Local → hosted.
Two pipes, one goal.

How trade evidence moves from the local SQL Server instance to (a) the local directory app at 127.0.0.1:8012, and (b) the hosted Render deployment at ep051-directory.onrender.com. Built from the actual diagnosis session on 2026-08-27/28 — every status below is either directly verified or explicitly marked unproven, never assumed.

Current known gap: the hosted publish pipe is fully bug-fixed and passes local integrity verification, but has never completed a real end-to-end publish — the live Render service returned intermittent 502s when sent a full 28MB/2000-strategy payload. Not yet root-caused on the server side (no Render log access from this session).
