Five SVG diagrams anchor the architecture story across README, the
public doc site and the landing page:
- 01-data-flow: source → ingest → store → read → surface
- 02-coach-pipeline: question → snapshot → prompt → provider chain → cited reply
- 03-self-hosting-topology: reverse proxy → app + worker → Postgres + image registry
- 04-source-priority: per-metric ladder with audit-trail kept/dropped lanes
- 05-security-model: three concentric layers plus rate-limit / audit / SSRF rails
Hand-authored SVG, no external dependencies, mirrored into the
healthlog-docs and healthlog-landing repos so each surface ships its own
copy.
