Twelve documents under docs/onboarding/ covering orientation, local setup, the repo map, per-domain deep dives, the cross-service contracts, CI and the release flow, infra and secrets, observability, task recipes, and a list of which docs in this tree are currently stale. Every command in the setup guide was run against this checkout: the backend suite (429 passed, 8 skipped), the frontend Go suite, a venv boot of the backend, and a build+boot of the Go frontend. Two findings recorded along the way: - static/units.js's F_REGIONS is guarded by no test, despite three source comments claiming "a test asserts all three stay identical". The Go test only cross-checks the Go copy against the backend's Python. All four copies are currently identical. - backend/ and frontend/docker-compose.test.yml still default to the retired emi/thermograph-backend/app image path, and the frontend harness pins the split-era v0.0.2-split-ci tag.

thermograph
The Thermograph monorepo — the split repos reunified (2026-07-22) with full history via subtree merges, while keeping everything the split was actually for: per-domain images, per-domain deploys, and an async FE/BE contract.
Domains
| Dir | What | CI |
|---|---|---|
backend/ |
FastAPI graded-climate API, accounts, notifications (Discord bot, push, mail), data pipeline | build-push → image emi/thermograph/backend; deploy |
frontend/ |
Public client: static JS/CSS + SSR pages | same build-push / deploy workflows, matrixed by domain; image emi/thermograph/frontend |
infra/ |
Compose (beta, LAN dev) + the Swarm stack (prod), deploy scripts, terraform, SOPS secrets vault, ops cron | infra-sync (host checkout + secrets render), secrets-guard, ops-cron |
observability/ |
Loki + Grafana + Alloy stack | observability-validate |
thermograph-docs deliberately stays its own repo (ADRs + runbooks, no
build artifacts, different change cadence).
New here?
docs/onboarding/ is the developer onboarding
path: orientation, verified local-setup recipes, a per-domain deep dive, the
cross-service contracts that break silently, the release flow, and a list of
which docs in this repo are currently stale.
How CI stays decoupled
Every workflow in .forgejo/workflows/ is path-filtered to its domain: a
push touching only frontend/** builds/deploys nothing else. Images stay
separate (emi/thermograph/backend, emi/thermograph/frontend, each tagged
sha-<12hex>), deploys stay per-service (infra/deploy/deploy.sh SERVICE=backend|frontend|all), and the API version contract
(GET /api/version, PAYLOAD_VER) still lets FE and BE ship out of lockstep.
The one intentionally coupled piece is pr-build.yml: a single always-running
gate required check that builds only the domains a PR touches (a
path-filtered required check would deadlock auto-merge).
Branch model (unchanged from the split era): PRs → dev, main → beta,
release → prod; infra tracked via main on all hosts.
