# WeatherTool update roadmap

This document tracks proposed WeatherTool improvements. Work should be delivered in small, reviewable phases rather than as one large rewrite. Each phase should leave the application runnable and independently testable.

## Environments and workflow

- **Windows source workspace:** source editing, review, and Git operations only; do not install dependencies, compile, build, run, or test here.
- **Rocky development and staging:** the sole compile, build, development-runtime, and test environment, with production-like Docker staging at `http://192.168.1.101:9190`.
- **Git over SSH:** Windows pushes reviewed commits to a private bare repository on Rocky; the Rocky staging checkout pulls those commits and rebuilds.
- **Ubuntu VPS deployment:** release `b0b58d2` is publicly operational behind Cloudflare strict TLS, Nginx, and Authelia, ingesting real LVĢMC open-data station/water-temperature observations on a schedule; the `weather` table was wiped and re-populated fresh once the UTC/local timezone mismatch between sources was fixed. FTP (`ENABLE_LVGMC_FTP_JOBS`) stays `false` on both Rocky and the VPS pending a real answer from the LVGMC contact about the `ltv` account's connection/rate policy — see Phase 7 for the full, still-unresolved diagnosis. The VPS does not compile or build the project.
- **Workplace production:** remains separate until changes are reviewed, tested, and explicitly approved for workplace use.

Do not synchronize `.env`, database directories, generated dependencies, build output, or provider credentials between machines.

## Working principles

1. Make one coherent change at a time.
2. Record the existing behavior before intentionally changing it.
3. Keep dependency updates separate from UI redesign and functional changes.
4. Review and commit on Windows, then deploy and test the same commit on Rocky staging.
5. Use synthetic or sanitized data outside the workplace environment.
6. Never enable external provider schedules with placeholder credentials.
7. Do not connect staging to workplace services without explicit authorization.

## Phase 0 — Reproducible development baseline

Status: in progress

- [x] Review backend, frontend, deployment, and security structure.
- [x] Run the project locally through Docker Desktop.
- [x] Add configurable host port and scheduled-job switch.
- [x] Add deterministic synthetic station data for the repository station set and the Faktiskā-required Valmiera position.
- [x] Create an isolated Rocky Linux staging deployment.
- [x] Keep staging PostgreSQL private to its Compose network.
- [x] Commit the baseline changes and establish the Git-over-SSH workflow.
- [x] Document normal build, seed, frontend deploy, source rollback, and current operational limitations. (Database backup/restore remains pending.)
- [ ] Capture representative screenshots and expected API responses.

## Phase 1 — Behavior discovery and bug inventory

Status: in progress

- [ ] Walk through every page with synthetic data.
- [x] Document the current understood purpose of each workflow; validate it with workplace users over time.
- [x] Separate analytical dashboard features from broadcast-graphic authoring tools on the city-results map.
- [ ] Record unclear controls, missing units, broken states, and layout problems.
- [ ] Fix the `atmPressire` frontend field typo.
- [ ] Fix shifted Database export columns caused by duplicated `tempMax`.
- [ ] Correct malformed integer route handling.
- [ ] Add consistent loading, empty, and error states. (City selection empty state completed.)

## Phase 2 — Test safety net

Status: in progress

- [ ] Add backend route tests for representative station and country queries.
- [ ] Add database integration tests for aggregation and export behavior.
- [ ] Restore and expand CSV parser tests.
- [ ] Add GRIB parser boundary and malformed-file tests.
- [ ] Add security tests for invalid fields, filenames, offsets, lengths, and date ranges.
- [ ] Add frontend type checking and critical workflow smoke tests.
- [ ] Run tests automatically before staging deployment.

## Phase 3 — Dependency modernization

Status: in progress — frontend maintenance complete; backend maintenance pending

The first observed frontend install reported 15 vulnerabilities: 1 critical, 10 high, 3 moderate, and 1 low. The frontend dependency tree was reviewed in controlled groups, obsolete packages were removed, and both the complete and production-only npm audits now report zero known vulnerabilities at commit `de6f279`.

- [x] Capture and review the full npm audit report.
- [x] Establish that the production dependency audit is primarily blocked by `solid-js@1.9.4` resolving vulnerable `seroval@1.2.0`; confirm that the full audit also contains development-tool advisories.
- [x] Update direct frontend dependencies in controlled groups.
- [x] Replace or remove obsolete frontend packages where appropriate.
- [x] Add a committed TypeScript typecheck command and validate the updated frontend with a clean `npm ci`, typecheck, and production build.
- [x] Resolve the remaining transitive build-tool advisories after reviewing the proposed `npm audit fix` changes; verify full and production-only audits at zero.
- [x] Build, smoke-test, checksum, transfer, and deploy a commit-addressed VPS release containing `de6f279` or later without restarting PostgreSQL or Authelia. (`ef64895` deployed 2026-08-22.)
- [ ] Visually compare every page and representative exported PNG in the deployed dependency-maintenance release.
- [ ] Update Scala within the supported 2.13 line before considering larger migration.
- [ ] Update http4s, Doobie, Circe, Cats Effect, Logback, and test libraries in compatible groups.
- [ ] Replace release-candidate dependencies with stable releases where possible.
- [ ] Update Docker base images deliberately and pin reproducible versions.
- [ ] Verify database compatibility and generated artifacts after every group.

Dependency changes must not be combined with a visual redesign unless a package migration strictly requires it.

## Phase 4 — Security hardening

Status: pending

- [ ] Rotate and remove the API key exposed in a source comment (`src/main/scala/fetch/dmi/FetchService.scala:56`, a DMI HARMONIE key introduced 2025-02-01; confirmed the repo's GitHub `origin` is public, so this has been externally exposed for roughly 18 months — decision on rotation vs. a git-history rewrite is still open).
- [x] Remove credentials/internal error details from connection-error messages: `/api/fetch/lvgmc/stations` was returning `error.getMessage` straight to the caller; now logs it server-side and returns a generic message.
- [ ] Protect or remove debug and administrative endpoints. Partial: `/api/fetch/lvgmc/stations` (the one that could trigger a real FTP login) is now gated behind `ENABLE_LVGMC_FTP_JOBS`, but `/api/debug/time`, `/api/debug/folder-structure`, and `/api/debug/delete-tmp` remain unauthenticated.
- [ ] Convert state-changing `GET` routes to appropriate methods.
- [ ] Introduce closed, validated weather-field and aggregation types. Partial: the one route that let a raw field string reach SQL now validates against `WeatherData.getKeys` (see below), but this is a route-level allowlist, not a closed type threaded through the codebase.
- [x] Eliminate raw user-controlled SQL identifiers: `/api/query/city/.../{field}/...` let an arbitrary path segment reach `Fragment.const` unescaped; added `ValidateField`, the same allowlist-against-`WeatherData.getKeys` pattern `/query/country` already used.
- [x] Validate and constrain filenames, resolved paths, offsets, and byte lengths: added `ValidateFileName` (allowlist regex, rejects `..` and separators including decoded `%2f`) and applied it to every route that concatenated a raw path segment into a filesystem or FTP path (`/debug/file`, `/show/grib`, `/grib/binary-chunk`, `/show/lvgmc-forecast`); hardened `ValidateInt` to reject negative integers; capped `binary-chunk` read length at 64MB to remove an unbounded allocation.
- [ ] Add query-range, response-size, request-rate, and timeout limits.
- [ ] Restrict CORS to intended origins.
- [ ] Define authentication and authorization requirements for workplace deployment.

## Phase 5 — Runtime reliability and operations

Status: pending

- [ ] Manage custom executors as resources and close them cleanly.
- [ ] Remove explicit `System.gc()` calls.
- [ ] Supervise scheduled jobs independently instead of recursively restarting the application.
- [ ] Add application health and readiness endpoints.
- [ ] Add structured logging without leaking secrets.
- [ ] Define PostgreSQL and GRIB-data backup/restore procedures.
- [ ] Add container resource limits and deployment health checks.
- [ ] Document monitoring, update, rollback, and incident procedures.
- [x] Harden `WarningService`: bound LVĢMC retry attempts to once per cache window during an upstream outage, isolate one warning's polygon-fetch failure from the rest instead of failing the whole response, verify the CKAN polygon filter against real column-type ambiguity rather than guessing, and log (rather than silently swallow) a defaulted vertex-order value.

## Phase 6 — Information architecture and UI redesign

Status: pending

- [ ] Identify primary user roles and their most frequent tasks.
- [ ] Separate historical analysis, live station monitoring, database inspection, HARMONIE visualization, and broadcast graphics.
- [ ] Replace technical/internal labels with task-oriented language.
- [x] Replace the copy/paste weather-character workflow with a direct visual font-glyph picker, bulk assignment, and city exceptions.
- [x] Explain and visually separate manual wind and weather-icon inputs from queried data.
- [ ] Add units, legends, contextual help, and clear date semantics.
- [x] Establish the first responsive layout, typography, spacing, and component-system foundation.
- [x] Add an explicit PNG download workflow for broadcast map assets.
- [x] Implement the fixed Faktiskā station set, latest-temperature loading, manual overrides, and locked 3840×1440 export.
- [x] Make Faktiskā weather-symbol selection manual while keeping placement automatic and badge-relative.
- [x] Replace Daira font glyphs with normalized 256×256 transparent image assets across the editor and canvas renderers.
- [x] Add a separate Latvian-named Ūdens workspace with fixed manual fields.
- [x] Calibrate and visually validate independent Ūdens exports at 1920×1080 and 3840×1440 against the supplied production templates.
- [x] Bundle the confirmed Monda Regular/Bold files and replace temporary Rubik rendering.
- [ ] Perform pixel-level Monda comparison against the authoritative production masters.
- [x] Add a separate Latvian-named Brīdinājumi workspace that renders current LVĢMC warning polygons without manual tracing.
- [x] Add production border overlay artwork and feathered warning-polygon fills to Brīdinājumi.
- [x] Replace Brīdinājumi's 4-corner bounding-box projection with an affine fit calibrated against the same validated Kartes/Faktiskā city pixel positions.
- [x] Limit the Brīdinājumi canvas to one operator-selected warning (superseded below by multi-warning selection), remove the on-canvas legend, collapse card detail to phenomenon/severity by default with full detail on click, and pre-fill the title from the selected warning's phenomenon.
- [x] Redesign Brīdinājumi warning cards as compact phenomenon-icon chips and move full warning text into a dialog popup over a dimmed, blurred backdrop.
- [x] Give Brīdinājumi chips a hover state where the severity-colored icon capsule expands to fill the chip, adapted from a reviewed external Uiverse.io reference component.
- [x] Split Brīdinājumi's warning selection (checkbox, drives the map) from viewing a warning's detail (clicking the chip, opens the popup) so choosing a map warning no longer forces the popup open; widen the detail popup for readability.
- [x] Replace single-warning selection with multi-select checkboxes so combined-severity newsroom maps (e.g. yellow + orange wind together) can be produced; re-add severity-ordered compositing of every checked warning's polygons. Restyle chips as narrower, fully severity-colored, white-icon/white-text buttons, and port a reviewed Uiverse.io checkbox component for the selection control.
- [x] Add per-warning editorial weather-symbol placement to Brīdinājumi, reusing Faktiskā's existing symbol set: drag to move, drag a corner handle to resize, stored as canvas-fraction coordinates so placement holds across both export resolutions; the drag/resize affordance is preview-only and never reaches the exported PNG. This is the app's first direct-manipulation canvas control (everywhere else is plain form inputs).
- [ ] Decide whether Brīdinājumi should actively prevent checking warnings of different phenomena together, or continue leaving that as an operator responsibility.
- [ ] Tune Brīdinājumi feather-blur bleed at sharp coastline curves (e.g. the Gulf of Rīga indentation).
- [ ] Test target resolutions and real workplace display conditions.
- [ ] Check keyboard navigation, contrast, focus states, and screen-reader labeling.

## Phase 7 — Real data and production readiness

Status: in progress

Phased plan: real station/temperature data first, then Harmonie once DMI
credentials are registered, then remaining sources. Synthetic data is kept
running in parallel until each real source is proven, not cut over in one step.

- [ ] Confirm the actual workplace deployment topology and current deployed commit.
- [x] Find a credential-free real alternative for current station observations:
      LVĢMC also publishes `hidrometeorologiskie-noverojumi` on `data.gov.lv`
      (the same free, keyless CKAN API already used for Brīdinājumi warnings),
      including a 48h rolling "operational" resource with the same fields the
      private FTP feed provides (minus `visibilityMin`/`dewPoint`/`sunDuration`,
      which aren't published there).
- [x] Add `fetch.lvgmc.OpenDataStationService`, pivoting that feed's tall
      `{STATION_ID, ABBREVIATION, DATETIME, VALUE}` rows into the existing
      `WeatherData` shape via a verified `STATION_ID → city` map (32 of the
      app's 37 tracked cities have a direct station), and schedule it in
      `Main.scala` (minutes 15/45) alongside — not replacing — the existing
      FTP fetch, writing into the same `weather` table via the existing
      `PostgresService.insertInWeatherTable` upsert.
- [x] Verify end to end on Rocky: real rows confirmed in `weather` via direct
      SQL, Faktiskā's 13 fixed stations rendering real current temperatures
      (Valmiera, the one city with no matching open-data station, correctly
      falls back to older synthetic data via the existing stale-observation
      UI rather than breaking), and Kartes' aggregate query API returning
      sane blended real+synthetic values.
- [x] Stop synthetic data generation now that real data is verified and this
      tool may plausibly be used against live broadcasts, where mixed
      real/fake data — both shown identically as "older observation" — is a
      real hazard, not just messiness: removed `dev/seed_weather.sql`, the
      `seed` Compose service, and the README section describing it.
- [x] Wipe the synthetic rows already sitting in the `weather` table on both
      the VPS and Rocky (both backed up first — VPS to
      `/srv/weathertool/backups/pre-real-data-release/`, Rocky to a local
      `pg_dump` — before truncating) so history going forward is real data
      only, not a mix — confirmed Valmiera (no matching open-data station)
      now shows no data rather than a stale synthetic fallback. Cities with
      no matching open-data station (Valmiera, Cēsis) should show no data
      rather than falling back to old synthetic rows — deferred by design,
      revisit once a real source is found or accepted as permanently
      unavailable.
- [x] Deleted the dead `METEO_*` fetch path (`fetch/csv/FetchService.scala`,
      its empty test, and its env vars everywhere). Confirmed via git history
      it wasn't a separate vendor: the first commit (2023-04-13) included
      real sample CSVs from it with a Latvian header identical to the
      LVGMC/open-data fields — the same underlying LVĢMC data, just an
      earlier delivery mechanism superseded by the FTP feed and never
      cleaned up. It was never wired into anything that runs.
- [x] Split scheduled jobs so the working open-data fetch (and cleanup) can
      run without the FTP/Harmonie jobs' placeholder credentials
      crash-looping the whole app: `ENABLE_SCHEDULED_JOBS` now only gates
      the safe jobs; a new `ENABLE_LEGACY_PROVIDER_JOBS` (default false)
      independently gates the FTP station fetch and Harmonie fetch. Turned
      the former on for Rocky staging; real station data now accumulates
      automatically every 30 minutes with no manual trigger needed.
- [x] FTP (`fetch/lvgmc/FetchService.scala`) credentials obtained 2026-08-23
      (`ftp.meteo.lv`, user `ltv`) and verified working against both a
      sample file and the real production file (`Latvija_faktiskais_laiks.csv`)
      via a manual `sbt runMain` check before any scheduling was touched.
      No code changes were needed to use them — confirming the original
      design intent. Split the combined `ENABLE_LEGACY_PROVIDER_JOBS` flag
      into independent `ENABLE_LVGMC_FTP_JOBS`/`ENABLE_HARMONIE_JOBS` flags
      first, since real credentials for the two providers arrive on
      different timelines and a single flag would have enabled Harmonie
      (still placeholder) the moment FTP's were ready — caught this before
      it could crash-loop the app (the Grib job was ~15 min from its first
      scheduled run when this was noticed). FTP enabled on Rocky.
      Also found and fixed a real UTC-vs-local timezone mismatch while
      verifying FTP alongside open-data: both write into `weather.dateTime`
      with no conversion, but the open-data portal's DATETIME is UTC while
      FTP's "Laiks" column is already local — silently present since
      open-data went live, only becoming an active problem now that a
      second, correctly-labeled source exists alongside it. Fixed by
      converting open-data's timestamps to Europe/Riga at ingestion
      (`OpenDataStationService`) and in the Ūdens water-temperature display
      (`WaterTemperatureService`, same root cause, display-only). Also
      hardened `insert_weather_table.sql`'s upsert from a blind overwrite to
      `COALESCE(excluded.field, weather.field)`, since open-data's rows
      always carry null visibilityMin/dewPoint/sunDuration and an empty
      phenomena array — a blind overwrite would silently erase FTP's real
      values for those fields whenever open-data's write landed later.
- [x] Went live on both Rocky and the VPS with all of the above: backed up
      and wiped both `weather` tables (Rocky: `/tmp` scratch backup this
      session; VPS: `/srv/weathertool/backups/pre-timezone-fix-wipe/`) now
      that the timezone bug is fixed, so history going forward is correctly
      and consistently timestamped rather than mixing the old UTC-mislabeled
      open-data rows with correctly-local FTP rows. Fixed a second real bug
      found only when wiring up the VPS specifically: `deploy/vps/compose.yml`
      hardcoded `LVGMC_USER`/`PASSWORD`/`URL` to inert placeholder strings
      directly in the file (unlike `POSTGRES_*`, which already read from
      `.env.staging`) — real credentials in `.env.staging` alone would have
      had no effect until this was switched to the same `${VAR}` substitution
      pattern. VPS now runs release `3eddf95`/`dc04f66` with real FTP
      credentials (added directly on the VPS by the user, never typed into
      this session) and `ENABLE_LVGMC_FTP_JOBS=true`. Good thing this was
      watched instead of assumed safe: the VPS's first scheduled FTP fetch
      (19:13 UTC) failed with `Failed to login to FTP server`, and because
      `parMapN` cancels every sibling task the instant one throws, this
      cascaded all the way up through `Main.scala`'s top-level
      `handleErrorWith` — which tears down and rebuilds the *entire* app
      (DB connections, HTTP server, schedulers) and retries every ~5s. Not a
      Docker-level restart (`RestartCount` stayed `0`, since the JVM process
      itself never exited) but a real in-process crash-loop on the public
      site, repeating every ~2 minutes as the FTP schedule re-fired. Reverted
      `ENABLE_LVGMC_FTP_JOBS` to `false` on the VPS immediately (the user was
      already asleep; this is undoing a flag flipped minutes earlier as part
      of the same authorized change, not new destructive action, so didn't
      wait) — confirmed stable afterward, no fatal errors, public site
      responding normally again.

      Diagnosed before reverting further: from the VPS, `ftp.meteo.lv:21` is
      reachable and returns a normal vsFTPd banner, and an anonymous login
      attempt correctly gets rejected (`530 Login incorrect`) — so this is
      **not** a network/firewall problem, outbound FTP works fine from the
      VPS. The real `ltv` account specifically fails to authenticate from
      the VPS despite working from Rocky a couple of hours earlier with the
      same credentials. Two candidate causes, neither confirmed (didn't
      inspect the actual password value to check):
      1. A transcription error when the password was typed into the VPS's
         `.env.staging` (manual entry, real risk for a long decoded string).
      2. LVGMC IP-allowlists the `ltv` account to specific source addresses
         — common for partner/business FTP accounts — and the VPS's outbound
         IP isn't on that list even though Rocky's apparently is. The VPS's
         outbound IP is `57.128.250.38`, in case it needs to be given to the
         LVGMC contact for allowlisting.
      **2026-08-24 morning update: the two-machine-collision theory above
      does not fully hold.** Independently confirmed the `ltv` account
      itself isn't hard-locked (a FileZilla login from a separate PC on the
      same network succeeded, browsed `/ltv/tabulas`, saw
      `Latvija_faktiskais_laiks.csv` freshly modified — LVGMC's feed is
      alive). A manual isolated fetch from Rocky then succeeded too. But
      re-enabling Rocky's *scheduler* (`ENABLE_LVGMC_FTP_JOBS=true`, VPS
      confirmed still `false` the whole time) failed on its very next
      scheduled attempt, ~4 minutes after the successful manual test, on
      Rocky alone with nothing else touching the account. Three attempts in
      ~10 minutes, two succeeded and one didn't, with no pattern found yet
      (not simultaneity, not which machine, not obviously attempt spacing).
      Reverted `ENABLE_LVGMC_FTP_JOBS` to `false` on Rocky again immediately.
      **Decision: stop self-testing this via trial and error — every
      attempt might be feeding an unknown rate/session limit — and wait for
      the user to ask the LVGMC contact directly what the account's
      connection policy actually is.** Both Rocky and the VPS run open-data
      only until there's a real answer.
- [x] Researched DMI HARMONIE credentials while waiting on the above and
      confirmed live (not just from search results, which claimed a specific
      date that wasn't independently verified): DMI's Forecast Data EDR and
      STAC APIs no longer validate an API key at all — a direct request to
      both the old `dmigw.govcloud.dk` and the new `opendataapi.dmi.dk` with
      *no* `api-key` parameter returned real GRIB/STAC data from both. New
      collection-items STAC path confirmed as
      `https://opendataapi.dmi.dk/v1/forecastdata/collections/harmonie_dini_sf/items`,
      with the same `properties.modelRun`/`properties.datetime` schema
      `fetch.dmi.FetchService` already expects — no response-shape changes
      needed, just the domain and dropping real key handling (the app's own
      config loader still needs *some* non-empty string for
      `HARMONIE_EDR_API_KEY`/`HARMONIE_STAC_API_KEY`, but DMI ignores it).
      Not wired up yet — see "Harmonie verification (planned)" below.
- [ ] **Harmonie verification (planned, next session)** — the user confirmed
      this data is used daily today (exported as a numbered PNG frame
      sequence per forecast hour, zipped, imported into After Effects for
      the on-air animated forecast loop — confirmed directly in
      `SlideShow.tsx`'s `downloadImagesAsZip`), so getting it working
      correctly matters, but the code has real, untested risk after a long
      dormant period (no HARMONIE fixtures, no configured provider access
      in staging, ever, per the existing product-workflow notes). Real data
      access itself is solved (see above); what's unverified is everything
      downstream. Plan, in order:
      1. Fetch one real current GRIB file and confirm `parse.grib.GribParser`
         decodes it cleanly with sane values — the low-level GRIB2 parsing
         reads discipline/category/product generically per the spec, so
         likely still fine, but not yet checked against a real current file.
      2. Verify each frontend field renderer (`draw/temperature.ts`,
         `windDirection.ts`, `precipitation.ts`, `snowDepth.ts`) against real
         data via screenshot — check in particular whether "Crop Latvia"
         (`interfaces.ts`'s `CROP_BOUNDS = { x: 1906-1-660, y: 840, width:
         660, height: 620, angle: 26 }`) still aligns correctly. This is a
         hardcoded pixel/grid offset into HARMONIE's specific grid
         domain/rotation — there's already one commented-out earlier version
         of this constant, meaning it's been hand-recalibrated at least once
         before, so it's a real, not hypothetical, risk if DMI's grid
         definition has shifted at all since.
      3. Verify the frame-export ZIP workflow end-to-end with real
         multi-hour data — frame count, naming, timing — against the user's
         own older HARMONIE exports and existing After Effects projects,
         which they have on hand for direct comparison.
      4. Only then: update `HARMONIE_EDR_URL`/`HARMONIE_STAC_URL` to
         `opendataapi.dmi.dk` (see above), set
         `HARMONIE_EDR_API_KEY`/`HARMONIE_STAC_API_KEY` to any non-empty
         placeholder (DMI no longer validates them), flip
         `ENABLE_HARMONIE_JOBS=true`.
      5. Lower priority, later: the Harmonie workspace is still raw/English
         dev-tool UI ("Crop Latvia", "Contour", "Interpolate" checkboxes,
         unstyled file list) unlike the polished, Latvian, newly-redesigned
         Faktiskā/Ūdens/Brīdinājumi workspaces — worth the same treatment
         once the data/rendering itself is trusted.
- [x] Add real water temperature data for Ūdens: `fetch.lvgmc.WaterTemperatureService`
      fetches LVĢMC's open hydrological data (`data.gov.lv`, same free CKAN
      API), mapping one representative real station per named zone (coastal
      `SEDUT` stations for Jūra/Līcis, inland `WTEMD` stations for the four
      historical regions). Fetch-on-demand with in-memory caching only —
      water temperature has never been persisted or needed history, unlike
      station observations. The frontend auto-fills both min/max per zone
      from the real reading, mirroring Faktiskā's override/reset pattern.
- [ ] Investigate a real source for the LVĢMC forecast CSV workspace,
      following the same open-data-portal approach used for station
      observations and water temperature.
- [ ] Test scheduled ingestion failure and recovery behavior.
- [ ] Rehearse deployment and rollback using sanitized data.
- [ ] Obtain technical and operational review before workplace rollout.

## Phase 8 — Temporary VPS user acceptance

Status: in progress

- [x] Document the proposed isolated VPS topology and trusted Rocky-to-VPS release flow.
- [x] Choose `laikapstak.li` and `auth.laikapstak.li`, create their proxied Cloudflare DNS records, and activate Cloudflare delegation.
- [x] Record a read-only VPS inventory before provisioning and confirm ports, networks, storage, and capacity do not collide with existing services.
- [x] Provision a dedicated `/srv/weathertool` tree, Compose project, private network, database storage, and loopback-only application and Authelia ports.
- [x] Configure Authelia with one temporary shared account, Argon2id password storage, rate limiting, and temporary IP bans.
- [x] Add an exact-host Cloudflare origin certificate and Nginx authorization routing without disrupting the existing HOP site.
- [x] Build and verify commit-addressed images on Rocky, transfer and checksum-verify them on the VPS, and update only the application service. Current full-SHA image: `weathertool:138f57c808631dc17396b22ac0305b670fbcf776`; PostgreSQL and Authelia were not restarted.
- [ ] Complete UAT verification: public authentication and application health pass; direct-origin blocking, logout, throttling, PNG downloads, backups, logs, and rollback remain.
- [ ] Share the domain with newsroom testers without a walkthrough first, to observe unassisted intuitiveness, before providing any guidance.
- [ ] Run the month-long user test with manual releases and record feedback before any workplace-production decision.

## Known current limitations

- The fixed production PNG bases, browser/social metadata, reviewed frontend dependency updates, stabilized header navigation, authenticated API routing, the full Brīdinājumi warning-map workspace (including draggable per-warning symbol placement), hardened LVĢMC warning fetching, real open-data station/water-temperature ingestion, and the scheduler safety split are deployed in UAT release `138f57c8`; newsroom workflow validation is in progress.
- Link-preview crawlers cannot authenticate through Authelia; the final Nginx policy must deliberately expose only the minimum preview metadata/assets if WhatsApp previews are required.

- Both the VPS and Rocky `weather` tables now hold only real open-data station observations; their original synthetic rows were backed up and wiped 2026-08-23.
- LVGMC forecast CSV fixtures are not yet available.
- HARMONIE GRIB fixtures are not yet available.
- The private LVGMC FTP feed has real credentials as of 2026-08-23, but `ENABLE_LVGMC_FTP_JOBS` stays `false` on both Rocky and the VPS pending a real answer from LVGMC about the `ltv` account's connection/rate policy (see Phase 7). The DMI HARMONIE forecast feed remains gated (`ENABLE_HARMONIE_JOBS`, default off) pending real credentials — turned out not to need any (DMI dropped its key requirement), but wiring it up is deferred to a dedicated verification session (see Phase 7).
- Existing automated test coverage is minimal.
- Full Docker build context scanning on Rocky can fail on the container-owned `postgres/` bind directory; do not loosen its permissions.

| 2026-08-22 | `70fd24c` | Give Brīdinājumi chips a hover-expanding severity capsule, adapted from a reviewed Uiverse.io reference component | Yes — Rocky typecheck, build, and headless-browser screenshot verification of rest/hover/active chip states; deployed to VPS in release `b5150ab` on 2026-08-22 |
| 2026-08-22 | `6fbf672` | Split Brīdinājumi warning selection (checkbox) from viewing detail (chip click) and widen the detail popup | Yes — Rocky typecheck, build, and headless-browser verification that checkbox clicks change the map selection without opening the popup and chip clicks open the correct warning's detail without changing the selection; deployed to VPS in release `b5150ab` on 2026-08-22 |
| 2026-08-22 | `56b8716` | Replace single-warning Brīdinājumi selection with multi-select checkboxes and severity-ordered polygon compositing, and restyle chips as narrower, fully severity-colored, white-icon/white-text buttons with a ported Uiverse.io checkbox component | Yes — Rocky typecheck, build, and headless-browser screenshot verification of multiple simultaneous checked warnings compositing correctly on the map; deployed to VPS in release `b5150ab` on 2026-08-22 |
| 2026-08-22 | `6185dbf` | Harden `WarningService` against partial upstream failures: bounded outage retry, per-warning fetch isolation, a live-API-verified CKAN polygon filter, and visible logging for a previously-silent vertex-order default | Yes — Scala tests, Rocky full-stack rebuild verified against real live LVĢMC data (including a genuinely severe 52,345-point wind-warning polygon rendering correctly); deployed to VPS in release `6185dbf` on 2026-08-22, verified against live data on the VPS itself |
| 2026-08-23 | `c97875d` | Add draggable, resizable per-warning weather-symbol placement to Brīdinājumi, reusing Faktiskā's symbol set and image cache | Yes — Rocky typecheck, build, and headless-browser mouse-drag/resize verification against fixture warning data (the live LVĢMC feed had zero active warnings at test time); confirmed the exported PNG excludes the preview-only drag/resize handles; deployed to VPS in release `138f57c8` on 2026-08-23 |
| 2026-08-23 | `893a09a` | Add `fetch.lvgmc.OpenDataStationService`: real, free, keyless current station observations from LVĢMC's open-data portal, scheduled alongside (not replacing) the private FTP feed | Yes — Scala tests, manual `sbt runMain` fetch+write against the real feed on Rocky staging (1,577 rows, 33 cities), confirmed in `weather` via direct SQL, Faktiskā's 13 fixed stations rendering real temperatures with correct stale-fallback for the one uncovered city (Valmiera), and Kartes' aggregate query API returning sane blended values; deployed to VPS in release `138f57c8` on 2026-08-23 |
| 2026-08-23 | `cb25316` | Stop generating synthetic weather data (remove `dev/seed_weather.sql`, the `seed` Compose service, and the README section describing it) now that real data is verified and this tool may plausibly be used against live broadcasts | Yes — `docker compose config` valid, running Rocky stack unaffected (profile-gated service, no running containers touched); deployed to VPS in release `138f57c8` on 2026-08-23 |
| 2026-08-23 | `6ddfe73` | Split scheduled jobs (`ENABLE_SCHEDULED_JOBS` vs. new `ENABLE_LEGACY_PROVIDER_JOBS`) so the working open-data station fetch runs without the FTP/Harmonie jobs' placeholder credentials crash-looping the whole app via `parMapN` | Yes — Scala tests, Rocky rebuild deployed with the flag on: logs confirm only the safe jobs scheduled, FTP/Harmonie never attempted, app stayed up; deployed to VPS in release `138f57c8` on 2026-08-23 |
| 2026-08-23 | `39fcb3e` | Remove the dead `METEO_*` fetch path (`fetch/csv/FetchService.scala`, its empty test, and its env vars everywhere) — confirmed via git history it's the same underlying LVĢMC data as the FTP/open-data paths, just an earlier, superseded delivery mechanism that was never wired into anything running | Yes — Scala tests (2 suites now, down from 3, the deleted one was empty); deployed to VPS in release `138f57c8` on 2026-08-23 |
| 2026-08-23 | `4036d24`–`4b92272` | Add `fetch.lvgmc.WaterTemperatureService`: real, free, keyless water temperatures for all 6 Ūdens zones (2 coastal `SEDUT` stations for Jūra/Līcis, 4 inland `WTEMD` stations for Kurzeme/Zemgale/Vidzeme/Latgale), fetch-on-demand with a 15-minute in-memory cache mirroring `WarningService` rather than the persisted station-observation path, since Ūdens has never stored history | Yes — Scala tests, Rocky rebuild, direct API curl confirming real values for all 6 zones; caught and fixed one station-selection error (Daugavpils only reports water level, not temperature — swapped for Ludza) via direct verification before committing; deployed to VPS in release `138f57c8` on 2026-08-23 |
| 2026-08-23 | `5a92465` | Auto-populate Ūdens's min/max fields from `/api/water-temperatures` on load, mirroring Faktiskā's fetch/override/reset pattern, with per-zone manual-override tracking and an "Atiestatīt" reset button | Yes — Rocky typecheck, build, and headless-browser verification (Playwright in Docker, since `chromium-cli` wasn't available in this environment) confirming auto-populated values match the API, manual edit correctly flips a zone to "Manuāli" and enables its reset button, and reset correctly restores the fetched value; noted along the way that `/udens-temperatura` 404s on a direct hit (no SPA fallback yet, consistent with the known limitation already listed) but works via client-side nav; deployed to VPS in release `138f57c8` on 2026-08-23 |
| 2026-08-23 | `9eca9eb` | Fix the one-station-per-zone design catching a real problem after deploy: every zone showed the same value duplicated as both min and max ("19...19"). Classified all 65 LVĢMC stations that report water temperature (56 inland WTEMD, 9 coastal SEDUT) into the 6 zones by geography and report the real min/max across each zone's currently-reporting stations, dropping readings over 12h stale so one stuck sensor can't skew a range | Yes — Scala tests, Rocky rebuild, direct API curl confirming a genuine spread per zone (e.g. Vidzeme 11.4–18.7°C, traced the low point to a real fresh reading from a colder headwater station near Cēsis, not a stale-sensor artifact), and headless-browser screenshot confirming the UI renders the real spread (e.g. "11...19") with no console errors; deployed to VPS in release `138f57c8` on 2026-08-23 |
| 2026-08-23 | `69a5260` | Bring architecture/workflow docs current with real-data ingestion (removed synthetic-seed staging descriptions, documented Ūdens auto-populate, the scheduler split) | Yes — doc-only change, no rebuild needed |
| 2026-08-23 | `138f57c8` | **Full go-live VPS release**: deployed image `weathertool:138f57c808631dc17396b22ac0305b670fbcf776` (everything from `c97875d` through `69a5260` — Brīdinājumi draggable symbol placement, real open-data station/water-temperature ingestion, synthetic-data removal, scheduler split, `METEO_*` deletion, real per-zone water-temperature ranges), flipped `ENABLE_SCHEDULED_JOBS=true` on the VPS now that the open-data path is proven, and wiped the VPS `weather` table's original 12,784 synthetic rows down to 0 (Rocky's own table was left untouched — separate decision, not requested for this release) | Yes — exact release image smoke-tested on Rocky (healthy, real warnings/water-temperature data) before transfer; VPS PostgreSQL backed up to `/srv/weathertool/backups/pre-real-data-release/` before the wipe; checksum verified on both ends; `app` service recreated without touching PostgreSQL/Authelia; confirmed healthy container, working loopback and public HTTPS (302 unauthenticated page, 401 unauthenticated API — matching established behavior), real warnings/water-temperature API responses, the scheduled open-data job firing on schedule and landing 1,577 real rows within ~2 minutes, and a real (non-Valmiera) city query returning genuine current temperatures with Valmiera correctly absent rather than falling back to wiped synthetic data |
| 2026-08-23 | `744d706` | Rework the visual palette: layered blue-gray background gradient (sampled tones, iterated visually against Home/Brīdinājumi/Kartes) replacing the near-flat pale tint, while keeping buttons/icons/links on the original saturated accent blue; removed the "Testa dati" badge, a synthetic-data leftover | Yes — Rocky build and headless-browser screenshot comparison across Home, Brīdinājumi, and Kartes; deployed to VPS in release `f78b0a26` on 2026-08-23 |
| 2026-08-23 | `a1c2fd5` | Declutter Faktiskā: collapse "Jaunākās temperatūras" and "Kartes noformējums" by default behind toggles (with a manual-override-count badge so nothing's silently hidden), fix a real cascade bug forcing Faktiskā's resolution buttons into full-width left-aligned rows instead of a compact pair, restructure "Kartes noformējums" into distinct bordered cards, translate its still-English symbol/city-assignment block to Latvian ("Mākoņi pilsētām"), and collapse its city list to exceptions-only by default | Yes — Rocky typecheck, build, and headless-browser screenshot verification of the collapse/expand toggles, the exceptions-only city list, and the button fix; deployed to VPS in release `f78b0a26` on 2026-08-23 |
| 2026-08-23 | `5c00e48` | Fix temperature numbers rendering visually too high in their map badges: canvas `textBaseline: "middle"` centers on font em-box metrics, not visible glyph ink, and digits have no descenders — centered on actual glyph bounds instead, matching the technique already used correctly in Ūdens | Yes — Rocky build and headless-browser screenshot comparison of the map badges before/after; shared by Faktiskā and the older Kartes comparison map; deployed to VPS in release `f78b0a26` on 2026-08-23 |
| 2026-08-23 | `59bb499` | Promote Brīdinājumi from the "Vairāk" overflow menu into the always-visible header nav, and add a small icon to every visible nav item (reusing the same icons as their Home cards) | Yes — Rocky build and headless-browser screenshot verification at 1900/1440/1200px widths, confirming no overflow and correct active/overflow-menu state; deployed to VPS in release `f78b0a26` on 2026-08-23 |
| 2026-08-23 | `f78b0a26` | Deploy the full frontend design pass (background/accent rework, Faktiskā decluttering, temperature-badge centering fix, header nav) to the VPS — no database or scheduler changes, application-only release | Yes — exact release image smoke-tested on Rocky (bundle hash and headless-browser screenshot confirmed against the known-good local build) before transfer; checksum verified on both ends; `app` service recreated without touching PostgreSQL/Authelia; confirmed healthy container, matching bundle hash on the VPS, working loopback and public HTTPS (302 unauthenticated page, 401 unauthenticated API), and real warnings/water-temperature API responses |
| 2026-08-23 | `d7439a2b` | Fresh-eyes review of the whole design pass turned up two real issues, fixed here: `WindInputs` had no Latvian branching and was showing "Wind direction"/"Wind speed"/"Gusts" in English right under the freshly-translated "Temperatūra un vējš" heading on Faktiskā (threaded the same `productionTemplate` flag `MapView.tsx` already uses elsewhere), and a confirmed-unreferenced `.assignedSymbol` CSS rule was removed. The review also flagged two things left alone: a pre-existing (not introduced this session) `.symbolPalette`/`.selectedPreview`/`.currentSymbol` cross-file class collision in `weatherIcons.css` currently masked by `!important` rather than actually resolved, and a naming nit on "Mākoņi pilsētām" (the section assigns arbitrary weather symbols, not just clouds) — both worth a look later, not blocking | Yes — Rocky typecheck, build, and headless-browser screenshot confirming the wind fields now render in Latvian; deployed to VPS in release `d7439a2b`, exact release image smoke-tested (bundle hash matched) before transfer, checksum verified, container healthy, public HTTPS/API checks passing |
| 2026-08-23 | `e446f1f` | Consolidate `.symbolPalette`/`.selectedPreview`/`.currentSymbol` (used by both Faktiskā's `IconInputs.tsx` and Brīdinājumi's `Warnings.tsx`) into one real definition in `weatherIcons.css`, the file both actually import, removing the dead/duplicate versions in `mapGraphics.css` and the `!important` size patches that were masking the collision. "Mākoņi pilsētām" naming confirmed intentional — the newsroom users are non-technical and the same people who'll use this long-term, so intuitive-but-imprecise beats literally-correct-but-jargony | Yes — Rocky typecheck, build, headless-browser screenshot on Faktiskā (pixel-identical to before), and computed-style verification on both Faktiskā and Brīdinājumi confirming identical resolved CSS with no `!important`; caught one incidental fix for free (`.currentSymbol.empty`'s Inter font was silently losing to the `!important` rule, normal cascade now applies it correctly); deployed to VPS in release `e446f1ff`, exact release image smoke-tested (bundle hash matched) before transfer, checksum verified, container healthy, public HTTPS/API checks passing |
| 2026-08-23 | `2b5dff6` | Make the `weather` table upsert non-destructive: `ON CONFLICT DO UPDATE` was a blind full-row overwrite, so open-data's always-null `visibilityMin`/`dewPoint`/`sunDuration` and always-empty `phenomena` would silently erase real FTP values whenever open-data's write landed later for the same row. Switched to `COALESCE(excluded.field, weather.field)`, with `NULLIF` against an empty array specifically for `phenomena` since Scala's `List[String]` never maps to SQL `NULL` | Yes — Scala tests; found while wiring up real FTP credentials, before any real dual-source writes had happened |
| 2026-08-23 | `cab94d0` | Fix a real UTC-vs-local timezone mismatch: the open-data portal's `DATETIME` is UTC, stored into `weather.dateTime` with no conversion, while FTP's "Laiks" column is already local and also stored as-is — silently present since open-data went live (`893a09a`), invisible until a second, correctly-labeled source existed alongside it. Fixed by converting to `Europe/Riga` at ingestion in `OpenDataStationService` | Yes — Scala tests; verified live: at real local time 20:31 EEST the fix produces `dateTime=20:00` instead of the previous `17:00`, matching what FTP writes for the same real hour |
| 2026-08-23 | `3315f00` | Fix the same UTC-vs-local mismatch in Ūdens's `observedAt` display (`WaterTemperatureService`) — same open-data portal, same root cause, display-only (internal recency filtering was already self-consistent either way) | Yes — Scala tests; verified live via `/api/water-temperatures`: `observedAt` now matches real local time |
| 2026-08-23 | `3eddf95` | Split `ENABLE_LEGACY_PROVIDER_JOBS` into independent `ENABLE_LVGMC_FTP_JOBS`/`ENABLE_HARMONIE_JOBS` — real LVGMC FTP credentials arrived today, real DMI HARMONIE credentials haven't, and the combined flag would have enabled both together, crash-looping the app on HARMONIE's still-placeholder values via `parMapN` | Yes — Scala tests; caught before it could happen (the Grib job was ~15 min from its first scheduled run when noticed) and reverted within under a minute; re-verified after the fix that only "Fetch Weather Stations" scheduled, not "Fetch Grib" |
| 2026-08-23 | `dc04f66` | Fix `deploy/vps/compose.yml` hardcoding `LVGMC_USER`/`PASSWORD`/`URL` to inert placeholder strings directly in the file (unlike `POSTGRES_*`, which already read from `.env.staging`) — real credentials added to `.env.staging` alone would have had no effect until this switched to the same `${VAR}` substitution pattern. Enabled `ENABLE_LVGMC_FTP_JOBS` on the VPS | Yes — `docker compose config` syntax valid; VPS `app` container came up healthy with real credentials loaded (would have crashed immediately on missing-config if not) |
| 2026-08-24 | `6b9c7cf` | Fix path traversal, auth-bypass, and DoS findings from an independent fresh-eyes security review (requested by the user specifically to get a second, skeptical pass against the local Rocky version): a live-verified CRITICAL — `/api/debug/file/{fileName}` allowed unauthenticated arbitrary file read, confirmed by reading `/proc/self/environ` and leaking `LVGMC_PASSWORD`/`POSTGRES_PASSWORD` into the review's own output — plus the same raw-filename pattern in `/show/grib`, `/grib/binary-chunk`, and `/show/lvgmc-forecast`. Added `ValidateFileName` (allowlist regex; rejects `..` and separators including decoded `%2f`) and applied it everywhere a path segment reached a filesystem or FTP path; hardened `ValidateInt` to reject negatives; gated `/api/fetch/lvgmc/stations` behind `ENABLE_LVGMC_FTP_JOBS` (it could otherwise trigger a real, unauthenticated FTP login regardless of the flag) and stopped it leaking `error.getMessage`; added an explicit `/api/*` catch-all so an unmatched API route can never fall through to the SPA shell; capped `binary-chunk` read length at 64MB | Yes — Scala tests, Rocky rebuild, live curl verification of `%2f`-encoded and literal traversal payloads (404), the gated FTP route (503 while the flag is off), an unmatched `/api/*` route (404, not `index.html`), and legitimate filenames/queries still returning correct 200s |
| 2026-08-24 | `8c45d8d` | Fix SQL injection surfaced by the same security review: `/api/query/city/.../{field}/...` passed its `field` path segment unvalidated into `PostgresService.query`, which splices it into SQL via `Fragment.const` (unescaped) whenever the aggregate key is min/max/avg/sum/distinct, or whenever granularity is `hour` in the list branch. Added `ValidateField`, reusing the `WeatherData.getKeys` allowlist `AggFieldList` already applied to `/query/country`. `AggregateKey` values reaching `Fragment.const` elsewhere were already safe — they come from a closed ADT (`AggregateKey.fromString`), not raw input | Yes — Scala tests, Rocky rebuild, live curl verification that SQL-injection payloads in the `field` segment 404 and a legitimate query still returns correct data |
| 2026-08-24 | *(operational, no commit)* | Rotated Rocky's `POSTGRES_PASSWORD` following the security review, since the old value had been exposed into this session's context multiple times (two of my own sloppy shell commands, plus the `/proc/self/environ` read the review used as its traversal proof). Changed the role's actual password via `ALTER ROLE` against the running container (editing `.env` alone has no effect on an already-initialized PostgreSQL data directory), then updated `.env` and recreated the `scala` service. The Postgres container itself was also recreated as a side effect (its own `POSTGRES_PASSWORD` env interpolation changed too), which is harmless — that variable only takes effect on a fresh, empty data directory, not an existing one — but is worth knowing about | Yes — clean scala container startup with no auth errors, and a real query (`/api/query/latest-temperatures/Rīga`) returning live data over the new password |
| 2026-08-24 | `2c44888`–`b0b58d2` | Replace the hardcoded per-route static-file list (`/station`, `/cities`, `/latvia`, `/database`, `/harmonie`, `/lvgmc-forecast`, `/bridinajumi`) with a general SPA fallback: real files serve as-is, anything else falls back to `index.html` so the SolidJS router handles it client-side — fixes a real, user-reported bug where a direct hit (e.g. a browser refresh) on `/faktiska` or `/udens-temperatura` 404ed instead of loading the app, since those two routes were never added to the old list. A missing file under `/assets` specifically still 404s properly rather than silently serving HTML, so a stale tab after a future deploy gets a clean error instead of a confusing JS parse failure | Yes — first attempt silently no-op'd because the fix was built into a `git archive HEAD` image before being committed (classic mistake, caught immediately by re-testing and finding identical old behavior); after committing, verified via curl on all previously-working routes, both previously-broken routes, a missing asset (404), a real asset (200), and `/api` (200), then a full headless-browser render check (zero console errors, real data, correct nav state) on a genuine direct hit — not just HTTP status codes; deployed to VPS in release `b0b58d2`, verified the same way through both the loopback port and the public domain (Authelia gate still correctly redirects unauthenticated requests) |
