 **Injecting test data:** Run `backend/inject_test_logs.py` (or the inline docker compose command in README.md) to write test log entries for yesterday, then trigger parsing via `GET /api/parse`.
 
+### Admin dashboard — mobile build orchestration (implemented)
+
+Admin users can create mobile build requests, upload platform signing files, run preflight checks, trigger remote builds, monitor logs/status, and download generated artifacts.
+
+**High-level flow:**
+1. Admin creates a build request (platforms, identifiers, version/build numbers, release profile).
+2. Admin uploads exactly two files per selected platform:
+	- Android: keystore + descriptor JSON
+	- iOS: `.p12` certificate + `.mobileprovision` profile
+3. Backend preflight validates request completeness, file presence, platform requirements, and basic iOS CarPlay entitlement marker.
+4. Backend dispatches build via SSH to external build workers:
+	- Android worker runs `./do_android_build.sh`
+	- iOS worker runs `./do_ios_build.sh`
+5. Backend copies generated `.aab`/`.ipa` artifacts back, stores metadata/checksums, and exposes admin download URLs.
+
+**SSH contract (current implementation):**
+- Connect as user `buildbot` (password-auth expected in the build-control environment).
+- Remote app directory is `~/mobile_app`.
+- Uploaded signing files are copied into `~/mobile_app` before script execution.
+- Build scripts are executed from `~/mobile_app`.
+
+**Key backend files:**
+- [backend/app/api/mobile_builds.py](backend/app/api/mobile_builds.py) — mobile build endpoints, preflight, SSH execution, artifact collection
+- [backend/app/models.py](backend/app/models.py) — `MobileBuildRequest`, `MobileBuildUploadedFile`, `MobileBuildArtifact`
+- [backend/app/schemas.py](backend/app/schemas.py) — mobile build request/response schemas
+- [backend/app/config.py](backend/app/config.py) — `KMTN_MOBILE_BUILD_*` settings (hosts, scripts, paths)
+- [backend/app/main.py](backend/app/main.py) — router registration at `/api/mobile-builds`
+
+**Key frontend files:**
+- [src/app/admin/admin.component.ts](src/app/admin/admin.component.ts) — mobile build tab state/actions
+- [src/app/admin/admin.component.html](src/app/admin/admin.component.html) — upload/preflight/trigger/logs/download UI
+- [src/app/admin/admin.component.scss](src/app/admin/admin.component.scss) — mobile build panel styling
+- [src/app/services/mobile-build.service.ts](src/app/services/mobile-build.service.ts) — API client for mobile build endpoints
+- [src/app/interfaces/mobile-build.ts](src/app/interfaces/mobile-build.ts) — frontend build models
+
+**Current scope:**
+- Build artifact generation only (`.aab` and `.ipa`).
+- No automatic App Store Connect / Google Play upload.
+
 ## Common tasks
 
 - **Re-skin:** Edit colors in `_variables.scss` only.
