Two session models shared one process. `/v1/*` and `/v1/stream` are the live
one; `/api/sessions*` and `/api/compare_live_vs_still` were the earlier model,
still constructed on every `create_app()` through `build_legacy_scans` even
though nothing called them. The web client and `stream_client.py` speak only
`/v1`.
Deleted: `observe.py` (ScanService/PerceptionService/PerceptionAdapter),
`yolo_adapter.py` (imported only by the legacy builder), `pipeline.py` and
`test_suite.py` (the old single-image CLI, reachable only from each other),
`test_observe.py` (its Session* tests), the eight legacy route handlers,
`build_legacy_scans` with its two facades, `create_fastapi_app`, and the
`scans` parameter on `create_app`.
`IdentityRankingTests` moved to `test_identity.py` before `test_observe.py` was
deleted: those five ranking rules are the live path's contract, not the legacy
model's. `test_api.py` keeps every `/v1` and WebSocket test.
Verified: 246 tests OK (2 skipped), and a route dump of a freshly built app
shows no `/api/*` path with all nine `/v1` routes and the WebSocket intact.
docs/API.md is the full contract: run flags and environment, auth, coordinate
convention, the identity vocabulary, every REST endpoint and WebSocket message
with examples, the backpressure rule, what a client may rely on, the design
decisions with their rejected alternatives, measured performance, known
limitations, and notes for the future mobile client.
README.md (Vietnamese) now documents the client-server shape, both modes, the
flags, the API, the test commands, and the source layout. It also repairs the
PowerShell escape damage in the original file (backtick-r had become a line
break, backtick-b a backspace, backtick-a a bell), which had left the code
fences and file paths mangled.
test_real_model.py is the opt-in integration test (DORAYAKI_REAL_MODEL=1): it
guards the measured baseline (170 detections, 105 recognized on image.jpg) and
proves a pan keeps labels stable with no unexplained changes.
run_app.sh / run_app.bat pass arguments through to the server.
