# 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 | `backend-build-push` → image `emi/thermograph/backend`; `backend-deploy[-prod\|-dev]` |
| `frontend/` | Public client: static JS/CSS + SSR pages | `frontend-*` mirrors of the above; 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).

## 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.
