## 1. Environments

| Env | How it runs | API base | Auth | Tile providers |
|-----|-------------|----------|------|----------------|
| Development | `bun run dev` (Vite dev server, port 5173) | Vite dev proxy: `/api → http://localhost:8080` (configured in `vite.config.ts`) | Suite admin/ service running locally (typically via parent suite `docker-compose up`) | Suite-internal `satellite-provider` via env-configurable `VITE_SATELLITE_TILE_URL` (defaults to `http://localhost:5100/tiles/{z}/{x}/{y}` when unset). Cookie auth requires same-origin; running the SPA at `localhost:5173` and `satellite-provider` at `localhost:5100` cannot send the auth cookie cross-port — recommend reaching `satellite-provider` through the suite's local nginx OR running it with auth disabled in dev (per AZ-498 risk #2). `mission-planner/` keeps its own independent `VITE_SATELLITE_TILE_URL`. |
| Stage | nginx in container, ARM image `:stage-arm` | nginx `/api/<service>/ → http://<service>:8080/` (intra-cluster) | Stage suite admin/ service | Suite-internal `satellite-provider` on the same origin (nginx-fronted); cookie auth attached automatically. |
| Production | nginx in container, ARM image `:main-arm` | nginx `/api/<service>/ → http://<service>:8080/` | Prod suite admin/ service | Same as Stage. Replaces the previously-used external OpenStreetMap and Esri tile providers as of cycle 2 / 2026-05-12 (AZ-498) — production deploy is gated on the cross-workspace satellite-provider cookie-auth ticket landing (autodev Step 16). |

## 2. Configuration model

The SPA bundle is **fully static**. No env vars are read at runtime by the bundle. Every cross-environment difference is resolved at the **deployment edge** (nginx) or at the **suite-service level**.

| Concern | Where it's set | Notes |
|---------|----------------|-------|
| Backend API URL | nginx `proxy_pass` (`nginx.conf`) — same nginx config across stage / prod | Base URLs are intra-cluster service names (`http://annotations:8080`, etc.); the URL difference between environments is hidden by the orchestrator's DNS |
| Auth cookie domain | Set by suite admin/ service on `Set-Cookie` | UI does not control |
| Refresh-token lifetime | Set by suite admin/ service | UI tolerates any TTL |
| Satellite tile provider URL (main SPA) | `.env.example` declares `VITE_SATELLITE_TILE_URL`; resolved at build time via `getTileUrl()` (`src/features/flights/types.ts`) with `DEFAULT_SATELLITE_TILE_URL` fallback. Cycle 2 / AZ-498. |
| Satellite tile provider URL (mission-planner) | `mission-planner/.env.example` declares its own independent `VITE_SATELLITE_TILE_URL` | mission-planner only; not deployed |
| OpenWeatherMap API key + base URL (main SPA) | `.env.example` declares `VITE_OWM_API_KEY` + `VITE_OWM_BASE_URL`; resolved by `getOwmBaseUrl()` and the `flightPlanUtils.ts` builder. Closed AZ-448 / AZ-449 (no longer hardcoded). |
| OpenWeatherMap API key + base URL (mission-planner) | `mission-planner/.env.example` declares `VITE_OWM_API_KEY` + `VITE_OWM_BASE_URL`; `WeatherService.getWeatherData(lat, lon)` returns `null` and issues NO outbound `fetch` when the key is unset (fail-soft). Closed cycle 2 / AZ-499. The previously-committed literal value MUST be revoked at the OWM dashboard (manual deliverable — AC-42 / AZ-499 AC-7); `STC-SEC1C` defends against re-introduction. |
| Google Geocode API key (mission-planner) | `mission-planner/.env.example` declares `VITE_GOOGLE_GEOCODE_KEY`; `GeocodeService.geocodeAddress(address)` returns `null` and issues NO outbound `fetch` when the key is unset (fail-soft, console.warn). Closed cycle 2 / AZ-501 (AC-43). The previously-committed literal value MUST be revoked at the Google Cloud Console (manual deliverable — AC-43 / AZ-501 AC-6); `STC-SEC1D` defends against re-introduction. |
| `AZAION_REVISION` | Stamped into image at build time | For diagnostics |

## 3. `.env` strategy

Step 4 testability + cycle 2 added a workspace `.env.example` (resolved by Vite at build time via `import.meta.env.VITE_*`). Today it declares: `VITE_OWM_API_KEY`, `VITE_OWM_BASE_URL` (AZ-448 / AZ-449), and `VITE_SATELLITE_TILE_URL` (AZ-498). `mission-planner/.env.example` mirrors the OWM pair (AZ-499), declares its own independent `VITE_SATELLITE_TILE_URL`, and (AZ-501) adds `VITE_GOOGLE_GEOCODE_KEY` for the address-search lookup.

**Trade-off**: Vite resolves `import.meta.env.VITE_*` at build time, so `dist/` is environment-specific once a non-empty `VITE_OWM_API_KEY` is baked in — the OpenWeatherMap key (and any future build-time config) cannot be changed without a rebuild. This trades promotability for the air-gap-friendly pattern that lets a deploy ship with `VITE_OWM_API_KEY=""` (no OWM call, fail-soft `null` return) when the deployment must not touch the internet.

**Future direction** (still open):
- Move the OpenWeatherMap call server-side (`flights/` service) — would eliminate the bundled key entirely; the env-var hardening in cycle 2 reduces the urgency but does not remove the option.
- Introduce a runtime `/config.json` that nginx serves — would let ops change feature flags / tile URLs without rebuilding.
- OR keep the static bundle and continue using Vite's `import.meta.env` for build-time injection of safe-to-publish values (current approach).

## 4. Promotability

The same image (`:dev-arm`, `:stage-arm`, `:main-arm`) is built per branch from the same Dockerfile. Theoretically the `:dev-arm` image is functionally identical to the `:main-arm` image except for the `AZAION_REVISION` label.

In practice: branch separation is the gating mechanism. Once dev → stage → main propagation is normalized, the safer pattern is to build ONE image per commit and re-tag it across environments (immutable image promotion). The Woodpecker pipeline does not implement this today; it rebuilds per-branch.

## 5. Local-dev quirks

- **Vite dev proxy** (`vite.config.ts`) requires the suite to be reachable on `http://localhost:8080`. If the parent suite's docker-compose binds to a different port, the developer must edit `vite.config.ts` (no env-driven override today).
- **`bun.lock`**: committed (per `package.json`'s `packageManager` field). `package-lock.json` is gitignored.
- **`.idea/`, `.claude/`, `.superpowers/`**: gitignored — IDE / agent metadata.
- **Playwright entries in `.gitignore`**: present but aspirational — Playwright is not installed (Step 5–7 territory).
- **mission-planner**: has its own `.env.example` declaring `VITE_SATELLITE_TILE_URL`, (cycle 2 / AZ-499) `VITE_OWM_API_KEY` + `VITE_OWM_BASE_URL`, and (cycle 2 / AZ-501) `VITE_GOOGLE_GEOCODE_KEY`. Runs as a sibling Vite app; not bundled into the deployed image (per AC-31 / NFT-RES-LIM-04). Despite not being deployed, the keys must still be revoked at their respective dashboards because the literals were committed and exist in git history.
