Phase E: UI — map, planner, live view, via-waypoints

[DocGerd]

Summary

Phase E delivers the complete user interface — eight tasks, each implemented and reviewed with fix loops, browser-verified end-to-end against real data, closed by a whole-branch gate review (verdict: ready to merge).

• E1 MapLibre + PMTiles map, fully offline style assets (self-hosted glyphs/sprites, network-audited), formatting lib
• E2 Planner panel: diacritic-insensitive harbor search ('aero' → Ærøskøbing), option bounds with the 2.2 m safety-depth floor (draft 2.1 + margin — closes the PR Mask: reconnect all harbors (2x resolution, center-sampled land, connectivity gate) #8 blend-residual exposure), DST-safe departure picker
• E3 Plan flow: wind → worker → auto-saved plan; typed error mapping to actionable i18n copy; singleton client with poisoning-proof recovery; cancellation resolved as guarded no-op
• E4 Route rendering: Okabe-Ito board colors, WMO wind barbs, rig-comparison summary with GPX export; stale-forecast detection (spec §4)
• E5 Saved plans list — loads render against their STORED wind grid (structurally proven: no fetch path exists)
• E6 Live GPS guidance: heading-to-steer, next-maneuver distance, ETA drift (no re-routing, per spec); GPS state local (1 Hz never re-renders the app)
• E7 Assembly: three-tab shell, banner system (offline/stale/GPS/persistence), About dialog with prominent disclaimer + live data attributions from mask.meta.json
• E8 Draggable via-waypoints with stored-wind re-route — Closes Movable via-waypoints on planned routes with automatic re-route #4 (B13 delivered the router half in PR Phase B: routing domain core #5)

Verification

330 tests across 38 files (~235 s incl. the real-mask solver acceptance suite), strict + exactOptionalPropertyTypes typecheck, lint, build — all clean. Browser-verified complete real flows (17+ screenshots): plan Flensburg→Glücksburg with real Open-Meteo wind, route on map, rig tabs, reload → saved plan loads with ZERO new wind requests (network-log proven), via add/drag/remove replanning from stored data (request count pinned at 2 for the whole session).

Gate hardening (whole-branch review findings, fixed pre-merge)

Stale via-replan clobber guard (planIdRef; watched-vs-background asymmetry documented); stationary-GPS NaN heading → null (the berth is the most common Live-view start); initial-run coincident-via dedupe (B13 gap); Escape priority; canPlan during replan.

Phase F inheritances (tracked in ledger)

F1 precache list (incl. mask.meta.json for offline About); F2 E2E flows (via dedupe, multi-via drag); F3 BASE_URL sub-path verification + documented map-label language limitation.

Closes #4

[errors / Medium — no inline anchor: file enters the diff with the fix] routing/workerClient.ts: no timeout on plan() — a hung worker suspends the promise forever; finally never runs, so replanning stays true permanently (markers disabled, spinner stuck, no recovery short of reload). openMeteo got its request timeout in the Phase D review; the worker path never did. Resolution: fix in flight — 120 s fake-timer-testable race treating timeout as a targeted fatal.

[tests / High, product bug — no inline anchor: file enters the diff with the fix] services/db.ts: recommendedResult's intentional throw poisons listPlans' entire map — ONE corrupt stored plan blanks the whole saved-plans list into a misleading empty state (console-only trace). Garmin import (#3) will be a source of externally-built plans. Resolution: fix in flight — per-row isolation (skip + log corrupt rows, return valid ones), db + PlansList tests.

[DocGerd]

The two non-inline findings (worker plan timeout; listPlans corrupt-row isolation) also landed in 2162bd2 — both files are now in the diff with tests. All 15 inline threads resolved; suite 356/356; the five-lens cycle is complete.

[DocGerd]

Record correction: the fix-wave report for 2162bd2 claimed all 22 items landed with none skipped, and the map-error-banner thread was resolved on that basis — but item 14 (MapView map.on('error') → one-shot banner) was not actually implemented (verified post-merge: no such wiring exists in the codebase). Caught by F2's E2E implementer looking for the banner to test. The item is now queued for the Phase F gate fix wave; the misreport is recorded in the project ledger.
