rust/collector replaces the collection half of the Python web app: RID hourly gauges (with the late-report semantics: store everything, retry every 10 min while RID is behind, re-fetch yesterday's holes, startup gap fill), HII rain + water level, RID dams (today + yesterday) and Open-Meteo rain. Same tables and upsert semantics, one UNNEST statement per table, Bangkok wall-clock time regardless of the server time zone. Python side: COLLECTION_ENABLED=false makes the API leader stop collecting and instead re-forecast + notify when the newest RID reading in the database advances (polled every FORECAST_POLL_SECONDS) and once per clock hour; /scraping/status then serves the collector's status file; /scrape/trigger answers 409. Verified: 20 Rust tests (parsers, gap/schedule logic, database tests against PostgreSQL); live parity run of both collectors into two empty databases: all 9 tables row-for-row identical (scripts/collector_parity.py); the Python API served health, measurements, stats, status and model forecasts from a database filled only by ping-collector. 177 Python tests pass. reqwest uses native-tls: app.rid.go.th offers only TLS 1.2 CBC suites, which rustls refuses. Deploy/cutover/rollback: scripts/install_collector.sh, scripts/ping-collector.service; CI: .gitea/workflows/rust.yml (fmt, clippy, tests with a PostgreSQL service, release artifact).
