grabowski	7e642555b4	chore: remove the Python service; Python is the training stack only ... 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.	2026-10-18 17:15:07 +07:00
grabowski	6ae67dec63	feat(collector): forecast and ntfy in ping-collector; ThaiWater keeps alerts current at night ... Phase 2b/2c of docs/RUST_REWRITE.md. With FORECAST_IN_COLLECTOR=true (shared .env) ping-collector, after each cycle that brought newer RID or HII readings and at least hourly: loads the last 336 h (RID + HII mirror fill), fetches the rain forecast, runs every exported model (rust/forecast), stores forecast_history and forecast_current, and sends the ntfy notifications. The Python API then serves forecast_current as /forecast (computing in-process only when it is older than FORECAST_MAX_AGE_SECONDS) and neither forecasts nor notifies. ntfy (collector/src/notify.rs): a port of src/notify.py with the same topics, texts, hysteresis, capacity guard and notification_state keys, checked word for word on 751 messages generated by Python (testdata/gen_notify_cases.py). The change: for stations whose ThaiWater twin is the same sensor, a reading newer than RID's drives the level alerts (marked as ThaiWater telemetry), and the feed counts as stale only when neither source has a reading for 3 h. RID alone lagging is reported once after RID_STALE_ALERT_HOURS (18). This ends the nightly "gauge feed stale" / "recovered" pairs caused by RID's late reports. Commands: `forecast [--json] [--save] [--now] [--rain-file]`, `notify --dry-run`. scripts/forecast_parity.py compares Python and the collector on the live database (same moment, same rain); locally 48/48 rows identical. install_collector.sh: models export + that check on every install, --cutover-forecast (refuses on a failed check) and --rollback-forecast. Trees are packed into 24-byte nodes: 70 MB peak with all 15 models (was 140). Forecast values are written to NUMERIC as shortest round-trip text, so they round as psycopg2's do. DB test schemas get a counter (parallel tests collided on Windows' coarse clock).	2026-10-18 14:43:39 +07:00
grabowski	4e619aa2ae	feat(rust): ping-collector, phase 1 of the Rust rewrite ... 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).	2026-10-17 22:20:02 +07:00
grabowski	04ebdaa931	fix: RID collector keeps late readings instead of losing every evening ... RID's hourly report often lags 1-2 h in the evening. The cycle discarded the whole report unless it already held the current hour, the web-API loop then slept a full hour, and after 01:00 only today's report was fetched. Result: the 19:00-24:00 readings were dropped most nights (P.1 lost 00:00 on 23 of the last 60 days, 13 evening hours this week), the feed went stale from ~21:00 until morning and ntfy ping-status sent a stale/recovered pair daily. - run_scraping_cycle() upserts every reading the report has; "current hour present" now only decides the retry cadence (returned as before). - Yesterday's report is re-fetched while the store has holes in it (hours 22-24 are only reachable through that day's report). - Leader loop polls at :05 (RID_POLL_OFFSET_MINUTES) and retries every RID_RETRY_MINUTES (10) while RID is behind; HII/dams/rain once per clock hour; forecast precompute + ntfy when newer readings arrive or hourly. - Startup re-fetches holes from the last GAP_FILL_DAYS_ON_START (14) days. - /scraping/status: the leader shares its stats via a JSON file, so any worker reports them (was always 0 runs); adds feed_current, latest_reading, readings_saved.	2026-10-17 21:45:09 +07:00
grabowski	f4d42c90f4	fix: ntfy listens on the Tailscale address; monitor publishes to it directly ... The reverse proxy is a separate VPS on the tailnet, so a loopback-only ntfy was unreachable from it. install_ntfy.sh now binds the host's Tailscale IP (NTFY_LISTEN overrides). New NTFY_PUBLISH_URL: where the monitor POSTs, separate from the public NTFY_SERVER subscribers see, so an alert never waits on DNS or the proxy (first cycle logged 502s from Cloudflare while the domain was not yet proxied).	2026-09-12 00:28:29 +02:00
grabowski	777b230baf	feat: public flood notifications over self-hosted ntfy ... Anyone can now get push alerts on their phone without an account: the monitor publishes to an ntfy server (one Go binary, ~30 MB RSS) and subscribers pick topics in the free iOS/Android/web app. Semantics are transitions, never state. One message when a gauge crosses its warning or danger threshold, one all-clear when it drops back (0.10 m hysteresis), nothing while it sits above. A three-day flood is two messages; a quiet season is zero. Topics: ping-warning / ping-danger (basin digest), ping-<station>-warning / -danger, ping-p1-outlook (opt-in: model P(warning within 24 h) at P.1 rises through 50 %, clears below 25 %, message says it is experimental), ping-status (feed stale >= 3 h / recovered). Priority 5 on danger so it rings through Do Not Disturb. src/notify.py runs once per collection cycle in the API process (leader only, after the forecast precompute, same data the dashboard shows). Last-sent state lives in a notification_state table so a restart never re-sends; a failed publish leaves state untouched so the crossing is retried next cycle instead of lost. Off unless NTFY_SERVER is set. Dashboard: a "Get alerts" button (only when configured) opens a panel with the server, per-topic cards, ntfy:// deep links and web links, app store links and a disclaimer. EN + TH. GET /api/notifications feeds it. scripts/install_ntfy.sh: .deb install, server.yml (loopback listen, anonymous read, token-only write scoped to ping-*, 72 h cache, signup/ login/metrics off, tight visitor limits), systemd, user + token, .env. Verified against ntfy 2.28.0: anon publish 403, token publish 200, token on foreign topic 403, anon read 200, and a seeded crossing through the real _notify_transitions path arrived in the topic with priority, tags, click and action button. docs/NOTIFICATIONS.md has the deployment and reverse-proxy notes. Tests: 10 for the state machine (159 total).	2026-09-12 00:18:38 +02:00
grabowski	6eafb353b1	feat: RID large-dam daily collector — Mae Ngat storage/inflow/outflow ... POST app.rid.go.th/reservoir/api/dams (open, archive >=2009) collected hourly into rid_dams + rid_reservoir_daily; backfill script fetches only missing days so reruns repair holes and are safe alongside the live collector. /api/stats counts the new table via an engine fallback that works when HII collection is disabled. Mae Ngat (DAM_ID 200103) hit 113% usable capacity with ~19 MCM/day inflow in the Oct 2024 flood — candidate features for the next retrain.	2026-08-13 10:29:34 +07:00
grabowski	731f10910e	perf: stale-while-revalidate caching, bigger executor, cheap DB health probe ... Third on-box run: p50s healthy everywhere but tails at 60s — when a TTL expired under load, every concurrent miss parked an executor thread on the single-flight lock, exhausting the ~12-thread pool and timing out unrelated endpoints. All cached endpoints (latest, HII, stats, health) now use _cached_swr: fresh -> inline; expired-but-present -> the stale value is returned immediately and ONE background task refreshes; only a cold key (first request since startup) waits. Plus: dedicated ThreadPoolExecutor (EXECUTOR_THREADS, default 48) replaces the cpu+4 default, and DatabaseHealthCheck no longer re-runs the CREATE TABLE DDL suite on every probe (connect only when no live engine).	2026-08-12 12:32:38 +07:00
grabowski	96fedb3991	perf: single-flight /api/stats; fast-fail health probe ... The on-box rerun after the inline fast path showed the cached endpoints healthy (latest p50 72-160ms, HII ~100ms) but /api/stats at 81% timeouts and /health at 33%: stats had a cache but NO single-flight, so every concurrent miss ran the heavy whole-DB counts (~1.7M rows) in parallel, re-jamming Postgres and the executor — which also dragged uncached history windows into 60s timeouts. /api/stats now computes through _ttl_cached_stale (one computation per 5min TTL, stale served on failure). The health API probe fails fast (5s instead of 30s) and its cache TTL rises to 30s, so a slow upstream can no longer pin executor threads longer than the cache lifetime.	2026-08-12 11:55:49 +07:00
grabowski	d9c65bcf0c	perf: inline cache fast path; cache /health checks ... The on-box load test exposed the real stall: cache HITS were dispatched through asyncio.to_thread, so under load a microsecond lookup queued ~11s behind slow work in the ~8-thread default executor (endpoints answered inline — /forecast 4ms, /api/stats 2ms — while every to_thread endpoint sat at p50 8-17s). Handlers now check TTL caches inline in the async path via _cache_fresh() and only pay for a thread on a miss. /health results are cached for HEALTH_CACHE_TTL_SECONDS (10): its external RID-API probe plus DB query were occupying executor threads on every hit, which is what jammed the pool in the first place.	2026-08-12 11:48:05 +07:00
grabowski	1ec5cfb4df	perf: gzip responses; multi-worker serving with single collection leader ... GZipMiddleware (min 500 bytes) compresses the dashboard HTML ~4x and station JSON up to ~100x, end-to-end through the Caddy TLS terminator — production load testing showed the deployment is bandwidth-bound once the response caches hit, so compression is the capacity lever. WEB_WORKERS (default 2) runs uvicorn multi-process via the app import string. Every worker executes the lifespan, so a localhost lock port (COLLECTION_LEADER_PORT, default 8901) elects exactly one background-collection leader per machine — RID/HII polling stays once-per-cycle instead of once-per-worker; the lock releases with the process. Locust clients now send Accept-Encoding so future runs measure compressed transfer, as browsers do.	2026-08-12 11:34:12 +07:00
grabowski	039af8caac	perf: cache /measurements/latest; stale-on-error fallback for cached endpoints ... The response caches (HII feeds, and now /measurements/latest at 45s TTL — the endpoint every dashboard poll hits) share one helper, _ttl_cached_stale: single-flight per key, empty results never cached, and expired entries kept as a fallback. If a recompute fails (DB unreachable), the last good response is served with an X-Data-Stale: true header instead of a 5xx — during an outage the dashboard keeps showing the last real readings with their honest timestamps. TTLs: LATEST_CACHE_TTL_SECONDS (45), HII_CACHE_TTL_SECONDS (120).	2026-08-12 11:05:02 +07:00
grabowski	d27ca8bf40	perf: 120s TTL cache with single-flight on /api/hii/*/latest ... These endpoints ran an uncached latest-per-station aggregation on every request (p50 0.6-0.9s under load, ~30% of the traffic mix) for data the collector refreshes hourly. Responses are now cached per (feed, hours) for HII_CACHE_TTL_SECONDS (default 120) with a per-feed compute lock so a cache miss runs one query regardless of concurrency; empty results are never cached so recovery is immediate. Cached hits measure ~8ms. Cache is process-local behind a single helper — the seam where a shared backend (Redis) would slot in if the deployment ever moves to multiple workers; not warranted at one.	2026-08-12 10:58:19 +07:00
grabowski	b89c7e1915	feat: flood-verdict banner, violet rain palette, per-station bands, chip contrast, Umami ... UI/UX review backlog round 2 plus analytics: - at-a-glance verdict banner (role=status, aria-live) above the tiles: ok/watch/danger from P.1 level vs the official 3.70 m stage and the 24 h forecast, with a not-an-official-warning disclaimer + ThaiWater link (also added to the forecast card) - rainfall dots switch to a violet sequential ramp so they can never be confused with flow-status colors; legend gains 'Other markers' rows (grey no-data gauges, + bank-height sensors) - history-chart flood bands now use each station's own /forecast thresholds (P.1 official fallback) instead of hardcoded 3.0/4.5 - chipStyle(): contrast-safe text on all code/risk/stage chips (dark ink on amber/ochre, darkened fills for white ink); risk/stage ramps drop the blue step for a monotonic green-ochre-amber-red escalation - plain-language tooltips on the flow and capacity tiles - Umami: client script tag plus opt-out server-side middleware posting api-request events (fire-and-forget, 3 s timeout, never blocks)	2026-08-11 16:56:53 +07:00
grabowski	1845ef7203	feat: hourly HII/ThaiWater rainfall + backup water-level collection ... Poll the open api-v3.thaiwater.net public endpoints (rain_24h, waterlevel_load), filter to the Ping basin, and persist to new hii_rain_stations/hii_rainfall and hii_wl_stations/hii_waterlevel tables (auto-created; sqlite/postgresql/mysql). Water levels stay in their own tables since HII reports m MSL from a different station set; rid_code maps mirrors like ridhydro_P.1 to P.1 and offset_msl converts MSL to gauge datum. Runs every scraping cycle in web-api and continuous modes (hourly cadence even during 1-minute RID retry), one-shot via --collect-hii; docs/DATA_SOURCES.md catalogs all probed endpoints.	2026-08-11 14:44:53 +07:00
grabowski	9cac9c4d2a	style: apply black/isort across the repo; make CI mypy advisory ... The push-CI gates (black/isort/mypy) had never actually run before the branch-trigger fix, and the codebase predates them. Formatting is now black/isort clean repo-wide. mypy keeps running but non-blocking: 86 pre-existing errors are a separate cleanup, not a gate to hold hostage.	2026-08-10 15:57:00 +07:00
grabowski	49a3de0087	fix: restore station telemetry and make river flow visualization data-driven ... Station selection showed no history since 21ca844: Chart.js v4 datasets had parsing:false with plain number arrays, drawing empty axes. Remove the flag so the chart parses values again. Backend hardening for the same flow: - /measurements/history/{code} no longer 503s on non-Postgres configs; it falls back to the configured adapter (reversed to ascending order) - DB_TYPE defaults to postgresql when POSTGRES_CONNECTION_STRING is set and DB_TYPE is unset, so the .env psql wins over the sqlite default - zero readings (0.0) are no longer coerced to None, which would fail MeasurementResponse validation and 500 /measurements/latest Map visualization: - river segments are now colored, widened and dash-speed-animated by the discharge at the nearest gauge (same scale as the marker legend) - fix z-order bug that drew the animated flow line behind its casing - legend entries for river lines, reduced-motion fallback River geometry: rebuild ping-river-network.geojson from Overpass (110 -> 202 features), restoring missing Ping mainstem reaches through the Bhumibol reservoir and the Tak-Kamphaeng Phet braided section (unnamed waterway=river ways in OSM), with short synthetic connectors (connector: true) bridging remaining sub-8 km holes.	2026-08-10 10:30:05 +07:00

grabowski	4bc3d82773	Persist station CRUD across restarts via JSON config ... Station CRUD via the API previously mutated the scraper's in-memory station_mapping only, so changes were lost on restart (and the systemd service auto-restarts). - Extract the 130-line hardcoded station_mapping into bundled defaults at src/data/stations.json; the scraper loads from a runtime-writable config file (STATION_CONFIG_PATH, default stations.json) and falls back to the bundled defaults to seed it. - Add scraper.save_stations() with an atomic temp-file + os.replace write. - create/update/delete station endpoints now persist and roll back the in-memory change if the write fails; re-raise HTTPException so persistence errors surface as real 500s instead of being swallowed. - Backend-agnostic (works for the VictoriaMetrics deployment, which has no relational stations table). Runtime stations.json is gitignored. Also clears pre-existing flake8 debt in water_scraper_v3.py (unused imports, long lines, duplicate logging import) and dedupes the User-Agent to Config.USER_AGENT.	2026-07-22 12:51:29 +07:00
grabowski	f4c63cabef	Fix Matrix message formatting and harden security ... Matrix alerts: - Send HTML formatted_body (org.matrix.custom.html) so **bold** and URLs render instead of showing literal Markdown; add plain-text body fallback. Add dependency-free markdown_to_matrix_html/strip_markdown helpers with HTML escaping of station/message data. Security: - InfluxDB: bind untrusted station_codes as query params and cast limit to int (was f-string interpolation / injection risk). - VictoriaMetrics: escape Prometheus label values and coerce metric values to float, preventing exposition-format injection and None crashes. - web_api: run blocking scrape cycle via run_in_executor so it no longer freezes the event loop; make CORS origins configurable and only allow credentials with explicit origins ("*" + credentials is invalid/unsafe). - config: remove hardcoded root/postgres password fallbacks (raise instead) and stop defaulting VM_HOST to a real infrastructure hostname. Also remove unused imports and wrap long lines to satisfy flake8.	2026-07-22 12:07:05 +07:00
