grabowski	764764e07e	feat: refuse silent v3->v2 downgrade; monthly retrain timer with staged promote ... train_all() now raises RainUnavailableError when use_rain=True and the Open-Meteo history cannot be loaded, instead of logging a warning and writing gauge-only (v2) bundles over the deployed v3 set -- which is what the 2026-09-01 server retrain did unnoticed. --no-rain remains the explicit way to get v2. CLI exits 2 with a one-line error. Three tests cover the guard, the opt-out, and the v3 happy path. scripts/retrain.sh trains into models/.staging, refuses to promote unless metrics.json shows hgb-v3+ and >=14 trained stations, then renames bundles into place (previous generation kept in models/.previous). No API restart: predict.py reloads by mtime on the hourly precompute. water-monitor-retrain.{service,timer}: 1st of each month 03:30, Persistent, OMP_NUM_THREADS=4, Nice=15, same sandbox as the API unit. install.sh now does `uv sync` into .venv (one env rule; removes a stale venv/) and enables the timer. water-monitor.service in the repo matched neither the deployed unit nor the uv env; it now does (run.py --web-api, .venv, EnvironmentFile).	2026-09-11 21:37:11 +02:00
grabowski	f6570ac10f	chore: declutter the repo ... Removes 26 tracked files that no longer describe or serve the running system, verified one by one against the whole repo (source, tests, docs, README, Makefile, Dockerfile, .gitea workflows, pyproject, packaging spec) plus dynamic-reference paths, before deletion. Root (11): one-off launch/setup write-ups from the project's first weeks that document events which never happened the way they describe — a github.com publication (the remote is self-hosted Gitea) and a 15-minute scheduler (the service runs hourly). Also .gitlab-ci.yml (unused, CI is .gitea/), .env.postgres and setup.py.backup (a placeholder env file and a backup in version control), and the PyInstaller packaging trio build_executable.py / build_simple.py / ping-river-monitor.spec, which bundled docs that no longer exist and is not how this deploys. docs (9): stale guides superseded by DATABASE_DEPLOYMENT_GUIDE, GITEA_WORKFLOWS, FLOOD_FORECASTING and DATA_SOURCES, plus two snapshots (PROJECT_STATUS, PROJECT_STRUCTURE) describing a 4-file src/ that is now 39. scripts (5): one-shot bootstrap tools already run — init_git.sh/.bat, generate_badges.py, migrate_geolocation.py, encode_password.py. Every inbound reference was fixed rather than left dangling: README doc index and migration section, three Makefile targets, the docs.yml summary step, and the GITEA_WORKFLOWS resource list. src/ is deliberately untouched. The audit proposed removing several live modules; verification showed those proposals were mis-scoped and would have broken production. .gitignore now covers the agent tooling dirs, model eval output and editor/shell leftovers — the working tree had collected 56 zero-byte files named after fragments of shell commands. 136 tests pass; production modules import clean.	2026-08-14 13:45:03 +07:00

grabowski	4358d52d55	feat: ML flood-event forecasting from 8 years of gauge history ... Add src/ml/ package predicting, per station and per 6/12/24 h horizon, the probability of exceeding warning (3.0 m) and danger (4.5 m) levels plus expected peak level, trained on the 592k-row PostgreSQL history: - features.py: hourly grid with coverage gating and no future leakage; upstream stations enter at empirically measured travel-time lags (P.20 +17h ... P.103 +1h vs P.1); hour-of-day deliberately excluded (it encodes the scrape schedule, not hydrology) - train.py: HistGradientBoosting regression + warn/danger classifier heads per station x horizon, >=30-positives gate with calibrated sigmoid-on-regression fallback, strict temporal splits, per-event lead-time evaluation; guards against sklearn 1.9.0 crash on degenerate feature columns - predict.py: bundle loading with feature-name checks, heuristic fallback tier, get_latest_forecasts() for the API; raises when no models are trained so the endpoint 503s instead of serving persistence output as forecasts - data.py: Postgres-first loader (FLOOD_ML_DB_URL override), HTTP API fallback (flagged: that path backfills synthetic discharge), csv.gz cache - /forecast endpoint (15-min TTL cache) + dashboard flood-risk panel (hidden until models exist) - docs/FLOOD_FORECASTING.md: full system doc with measured deployment numbers (~335 MB RSS, CPU negligible, ~6 min full retrain) and retraining policy Validation: out-of-sample backtest of the record 2024 flood season (train <= Aug 2024) alerted 24-48 h ahead of the Oct 5 peak; 2025-26 test split: P.1 6h PR-AUC 0.974, recall 98.3% at 1% false-alarm rate. Also: fix P.81 station coordinates (was Ban Pong/Ratchaburi, 493 km out of basin; now 18.6936 N 99.0819 E per RID station page), pin scikit-learn==1.9.0 and numpy<2, gitignore model artifacts (~100 MB, train on the server via scripts/train_flood_model.py).	2026-08-10 12:49:47 +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
