Phase 4 of docs/RUST_REWRITE.md. Since 2026-10-18 ping-collector (rust/)
collects, forecasts, notifies (ntfy + Matrix) and serves the website/API;
nothing in production ran the Python service code any more.
Removed (~17k lines): the FastAPI app (web_api, schemas, health_check,
metrics, postgres_history, forecast_history, thaiwater), the Python RID
collector and CLI (water_scraper_v3, main, run.py), the notifier and Matrix
alerting (notify, alerting), the multi-backend adapters (SQLite, MySQL,
InfluxDB, VictoriaMetrics) with demo databases, models/validators/exceptions/
logging/rate limiter, ml/skill.py (served by Rust now), the migration tooling
(api_parity, collector_parity, e2e_notify, install_collector.sh,
gen_notify_cases.py, spikes/rust-forecast), Docker/compose/Grafana files,
sql/, the release workflow and the docs for all of that. Their tests went
with them.
Kept in Python: src/ml (training, evaluation harness, export; predict.py as
the reference the Rust forecaster is tested against), the HII and RID-dam
clients/stores for the archive backfills (their live collectors removed),
the backfill scripts, retrain.sh + timer, forecast_parity.py.
- PostgreSQL only: src/config.py is database_url() from POSTGRES_* / .env;
the stores lost their sqlite/mysql branches (and the 2026-08 column
migration). The database tests run against a throwaway schema from
TEST_DATABASE_URL (tests/conftest.py pg_url, skipped without it), as the
Rust tests do; CI gets a PostgreSQL service. 100 tests (66 without a DB).
- The notifier settings moved from src/notify.py into src/ml/export.py;
flood_config.json regenerates byte-identical.
- tests/test_dashboard.py checks every path the dashboard fetches against
ping-collector's router.
- Dependencies: fastapi, uvicorn, pydantic, influxdb, pymysql, psutil,
schedule, sphinx, pyinstaller, mypy, pytest-asyncio dropped; python-dotenv
1.1.1 explicit (it came in through uvicorn[standard]).
- Formatting contract extended to scripts/ and tests/ (reformatted once).
- scripts/install.sh is the one installer (fresh host or update, in place in
a checkout without touching its ownership): binary, units, uv sync, .env
defaults, removes the retired water-monitor.service and any old
--alert-check cron job, dry run + forecast check, restart, readiness wait.
- Docs, CLAUDE.md, CONTRIBUTING.md, .env.example, Makefile, unit comments
and Rust doc comments updated to the Rust service.
load_measurements() (DB path) patches missing station-hours from the
hii_waterlevel mirror telemetry: exact mirrors (P.1/P.103/P.20/P.4A/P.67/
P.75/P.82/P.84/P.92) plus bias-corrected P.81 (+9,340 h). Per-station
MSL->gauge offset is derived from >=168 h of series overlap, which
reproduces the published offsets for exact mirrors and absorbs P.81's
bias; P.76/P.77/P.85/P.87 HII twins are different physical sensors and
stay excluded. Training and serving share the loader, so both sides see
identical filled series; water_measurements is never written.
