doBrouter() ended with changed(), which nulled routeGeom and re-queued
doBrouter — an endless re-route loop where the road line was never drawn
(editor kept the straight line, distance unchanged). Draw directly instead
(updatePolyline/updateStats).
Verified end-to-end in the UI on a virtual display (Xvfb) against the
RouteServer: editor 'По дорогам' turns a 1.69km straight line into a 2.25km
road-following route; the gap-fill '🧩' overlay draws a shortest-road cyan
dashed line across a track's GPS dropouts. Docs (README/PROJECT_MAP/plan/log)
updated to match; router.js/poi.js now listed in PROJECT_MAP.
Points of interest (cafe, shops, water, toilets, bank/ATM, bus, shelter,
viewpoint, ...) as circular contrasting badges (emoji in a white/dark circle,
readable on light and dark tiles) — not pins. A 📍 control toggles the layer
and opens a per-category filter (checkboxes, remembered). Markers are culled to
the visible bounds and shown from zoom 13 (cap 500/view), on the recording,
track-detail and roads maps.
Data is bundled and fully offline: frontend/data/pois.json ([{la,lo,c,n}], 358KB,
5662 POIs) fetched once from Overpass for ~100km around Novocherkassk (the whole
bbox returned in one query; adaptive subdivision was ready if it had truncated).
Verified functionally on device: 124 badges rendered in view at z16 over
Novocherkassk with correct bounds/category culling; the live visual could not be
screenshotted (the WebView surface is black under CDP). frontend/data + poi.js.
A moon button on the recording, track-detail and roads maps inverts ONLY the
tile layer: body.dark-map applies `invert(1) hue-rotate(180deg) brightness(1.5)`
to .leaflet-tile-pane, so the track/route/roads/puck overlays keep their colours.
Works the same on offline (tiles_*.db) and online tiles — no keys, quotas or
tile repacking. The choice persists in localStorage (baldav_dark_map).
Chosen after ruling out dark tile providers (CARTO/Thunderforest/2GIS/Yandex —
keys/quotas/ToS/projection/RF-reachability) and the transport style (inverts
badly in dense city); plain OSM inverted looks good city and countryside.
Verified on device: filter on the tile pane only, overlay pane filter none,
button active and remembered.
Variant 5 from the findings doc, as GROUND TRUTH for validating the
from-track wind estimate — it does NOT feed kcal/power. Chosen scope
(per user): a toggle button now, binary "in the face" only, voice later.
- rec screen button "Ветер в лицо": tap opens a headwind interval, tap
closes it; the open state is highlighted and survives a screen re-render
- GPS.toggleWindMark()/_closeOpenWindMark(); recording.windMarks =
[{startTs,endTs}] ms, persisted to localStorage, written to the DB on
finish and restored on crash recovery (a dangling interval auto-closes)
- gps_sessions.wind_marks (JSON) + DB.setSessionWindMarks (separate from
finishGpsSession so recompute paths preserve marks); parsed in getGpsSession
- rec-bottom wraps now so the third button never overflows a narrow screen
Analysis (marks vs estimate) stays in tools/track once enough km accumulate.
Acted on docs/gps-model-findings.md (independent analysis of 156 rides).
Implemented:
- crrFromAccel extended past the old 0.008 ceiling: 7-11 -> 0.008,
11-15 -> 0.012 (packed dirt), >15 -> 0.020 (grass/rut/gravel). Rough
surfaces were undercounted ~3x. Applied to session median and per-point Crr.
- Auto walk-the-bike detection (single-speed only, gear_count 1/unset):
a normal-fix segment slower than the 30-rpm-cadence speed is the rider
pushing, not riding. Excluded from ride distance/speed/elevation (elevRef
reset so a pushed climb doesn't merge with the ridden one); effort counted
as walking, not bike physics. Every sub-threshold point excluded regardless
of duration; only runs >=30s reported as walked (walkBikeSec/walkBikeMeters).
gearCount threaded through every computeStats/finish caller.
Documented as known limitations (left as-is by decision, need calibration/DEM):
- kcal max(physics, MET) never sums the biological overhead, so climbs are
slightly undercounted (comment + README + PROJECT_MAP).
- absolute elevation gain is bounded by the raw GPS altimeter (tens of
percent; needs a terrain model / wired DEM preload).
- searchProducts: order-independent token AND (every whitespace word must appear
in name, any order), ranked full-substring > prefix > length. Fixes needing to
type words in the name's order.
- Cleanup of unlabeled junk (health-diet/ashan/fast-food, null source): keep-list
= magnit,5ka,ion,kdv,manual,recipe_import,gridnev. DB.cleanupUnlabeledProducts
deletes non-keep AND unused (food_log/recipe_ingredients protected); Settings
button 'Очистить продукты без магазина' with a counted appConfirm.
- Seed products_seed.db cleaned: 24443 -> 13008 (non-keep removed), seed_meta
version 10 -> 11, VACUUM (13.5MB -> 8.9MB). So future imports don't re-add junk.
On-device 11207 unused non-keep will be removed via the button (24 eaten stay).
- One direction indicator instead of two geo-arrows: an SVG divIcon L.marker
(rotateWithView) — a track-colored circle (20% darker) with white + 1px black
rings, plus a triangle pointing the ACTIVE source heading (compass in compass
mode, GPS course in GPS mode). Rotation = geo heading; rotateWithView keeps it
correct as the map turns. Replaces posMarker + compass/course arrows.
- Z-order via panes: roads -> roadsPane(240), route routePane(250), track
overlay(400), puck markerPane — tiles<roads<route<track<puck (track no longer
hidden under roads).
- Mini-compass shown only in compass mode; tap-to-calibrate kept.
- darkenHex helper; .rec-puck css (no default div-icon box).
build.rs now re-runs when the commit changes (cargo:rerun-if-changed on
.git/HEAD + the branch ref) so GIT_HASH never goes stale, and appends -dirty
when tracked code (frontend, src-tauri/src, build.rs) is uncommitted. Lets a
distributed APK be pinned to an exact source commit for regression tracking.
README documents versionName 0.1.NNN + hash traceability. Decision at b4fdc824144.
Exclude real GPS fixes coarser than the "Макс. погрешность GPS" setting
(minAccuracyM) from a track's stats and its drawn line. Non-destructive: the
points stay in the DB, so raising the threshold brings them back.
- GPS.filterByAccuracy(points, threshold?): drops points with a measured
accuracy above the threshold; always keeps points without accuracy (imported
GPX/FTB, older recordings) and estimated dead-reckoning fills (sentinel >=999).
- Wired into GPS.computeStats (top) so every recompute path funnels through it —
the "Пересчитать" button, "Пересчитать всё", and the post-de-jitter recompute.
Also into GPS.filterNoise so the detail-screen line matches the stats.
- Removes mild jitter detours that the spike filter misses (verified: 342 -> 334m
when a poor-accuracy nudge is dropped). Lower the threshold + Пересчитать to
apply; raise it to undo.
- Route editor (showRouteEditor): create ("Новый маршрут") or edit an existing
route's geometry in-app — tap to add, drag a point to move, tap a point to
delete. Save: new prompts a name (addRoute), edit rewrites points_json
(updateRoutePoints; drops stale elevations, re-fetch from the preview).
- Slope colouring in discrete 1% bands (green→yellow→red→brown→black, ≥10% black)
instead of degree buckets; colour-strip legend (slopeLegendHtml).
- Diagnostic logs compiled-in but silenced in release: get_app_info now returns
debug = cfg!(debug_assertions); JS installs a console.log filter that drops
lines starting with a diagnostic tag ([poll]/[recover]/[stop]/[GPS]/[HR]/[SD])
in release only. No more hand-adding/removing logs.
- Fix: saved-route overlay was invisible on the recording (rotating) map — it
flashed on pinch-zoom then vanished. leaflet-rotate keeps tile/overlay panes
inside _rotatePane, but the commented-out createPane override meant our custom
routePane attached to mapPane (outside rotation). Now parent routePane to
map._rotatePane when present; non-rotating maps unchanged.
See how hilly a hand-drawn route is BEFORE riding it.
- parseRouteGPX reads <ele>; GPS.routeElevStats computes cumulative distance,
grade-to-next, ascent/descent (1m hysteresis) and max grade over smoothed
elevations (filterAndSmoothAlt kills SRTM vertical noise).
- Route preview screen (tap a route name): map with a wide colored casing +
tappable altitude/grade points, elevation profile chart (steep >8% in red),
length/ascent/descent/max-grade, fullscreen expand/collapse.
- Casing colored by slope (deg: lime <2, yellow 2-4, red 4-6, black >6) or by
elevation (green->yellow->brown), toggled with an on-map ∡/⛰ button. Casing
drawn in a dedicated pane below the overlay pane, so a recorded track stays on
top; the same toggle is on the track-detail map too.
- fetchElevations tries, in order: GPXZ (Copernicus GLO-30, key from GPS
settings — stored in localStorage, never in git) -> open-elevation (SRTM) ->
open-meteo -> OpenTopoData (keyless). Import auto-fetches elevations.
- db.js: updateRoutePoints persists fetched elevations into points_json;
getRoutes reports hasEle. Route points are now {lat, lon, ele?}.
Native prompt at route import replaced with in-app appPrompt.
Fixes to the smoothing/routes UI reported on device:
- Blank detail after save/revert: showSessionDetail was called from inside the
open detail modal, stacking a second overlay; querySelector("#sd-map") then
hit the stale, already-initialized Leaflet map and threw, aborting the rest
of the render (map + speed chart). New reopenDetail() closes the current
detail (and its fullscreen-map child) and reopens fresh, like recalc/refine.
- Native confirm()/prompt() replaced with in-app appConfirm/appPrompt dialogs
(winStack + history integrated, hardware back cancels). Used for smoothed
save, route delete, route rename.
- Slow smoothed save: one UPDATE per point (4000+ IPC round-trips) replaced
with a chunked CASE update — 18 statements for 4366 points, params kept
under SQLite's 999 limit. Verified value-for-value on a copy DB.
- Closing the fullscreen map now also closes the smoothing panel (it is a
fixed element that otherwise lingered over the collapsed map).
- "≈" button active state now reflects panel-open only, not session.smoothed
(it looked permanently pressed after a save).
Docs: README + PROJECT_MAP updated for saved routes, de-jitter, accuracy_m,
routes table and new gps_points/gps_sessions columns. Version 0.1.393.
On stretches where the fix rate drops (dt > gapThresholdSec, incl. dead-
reckoning) the straight chord mis-measures the path, so computeStats now
estimates gap distance by avg(speed)*dt (capped at max speed; a tiny chord
over a long gap means the rider was stopped and the reported speed is stale
-> trust the position). A fast jump WITHOUT a time gap is a teleport glitch
and is dropped. Distance now depends only on ts + speed, not on the
`estimated` flag (which live points carry but DB rows don't), so the live
counter, Stop and recompute finally agree. Verified on a real ride: at
gapThreshold=30 -> 35.7 km / 1024 kcal (map-measured ~35 km); clean tracks
without gaps unchanged.
Settings: read GPS config on input+change (reliable on mobile), add a
"Save GPS settings" button and a "saved" toast so it's clear the value
persisted; changing gapThreshold + recompute now visibly applies.
- native_root(): pick app root by presence of gps_live/gps_points files.
app_data_dir() is the root directly on this Tauri; the old .parent().parent()
read the wrong dir, so background (screen-off) points were never imported.
- recoverFromFiles: match file->session by id/date, plus session id stamped
into the native file name (gps_points_<ms>_s<id>.jsonl) for exact binding
(gps_set_session_id -> Kotlin bindSessionIfPending). Proximity dedup +-2.5s,
recalc with noDelete (never runs the destructive glitch/>24h filter that
once wiped real rides), delete already-imported files. Progress bar UI.
- bike kcal is NET (daily balance already books BMR*activityLevel): pedaling =
max(physics power/efficiency, MET-net by speed), coasting (power<=0, the bike
would roll unpowered) = basal only. Elevation via cumulative hysteresis.
recomputeAllStats + "recompute elevation/kcal" menu refresh stored tracks
without touching points.
- live recording: the native file is the DB source of truth; watchPosition
only drives the live marker, so a fix is not stored twice with two timestamps.
- track list pagination, SAF local-file picker, tile regions from router.
- applyBearing: use h, not h - rotOffset. The .rec-screen (map + panel) is
CSS-rotated by rotOffset in landscape and setBearing adds another rotate on
the map pane; subtracting rotOffset cancelled the screen rotation for the
map only, gluing course to the portrait top edge while the panel turned.
Using h lets the map turn with the screen -> course points to physical top.
- Poll: guard the requestAnimationFrame yield with !document.hidden. rAF never
fires while the screen is off, so awaiting it there hung the import loop and
froze point import mid-walk (regression from the progressive-draw change).
- recoverSession: import missing native points by the SET of existing
timestamps instead of ts > maxDbTs. Sparse screen-gated points can have a
late max ts, so the old check imported nothing and left the track full of
gaps; also pass sensorData so bearing/accel/gyro are stored.
- stopRecording: replace the dead _lastNativeCount backfill (the variable
is never assigned → guard is always false → missed points were never
saved) with a full timestamp-based re-import from the native points
file, then recompute stats over the complete set. Fixes losing ~90% of a
track when recording with the screen off — the JS import poll is frozen
by the WebView while the screen is off, so only the native file had all
points.
- Poll: draw each imported point via a lightweight onImportPoint and yield
a frame every ~20 points so the track visibly grows as points transfer
on screen-wake catch-up (restores pre-batch behaviour, kept cheap).
- Native: hard-reject fixes coarser than the Min-accuracy setting (drops
coarse cell ~800m that stuck the track); remove low-accuracy and adaptive
relaxation branches so only accurate fixes are recorded, honest gaps otherwise
- Store bearing_deg per point (gps_points migration + addGpsPoint)
- Default Min-accuracy 20 -> 50m (one-time migration, respects user override)
- Fix: http_request was synchronous with no timeout; an unreachable host
(LAN sync on startup) blocked the whole UI ~30s. Now async + spawn_blocking
+ connect(4s)/global(12s) timeouts, fails in background without freezing
- Bundled prior work: course-up map orientation, compass calibration,
online elevation refine (open-elevation), distance gap-gate fix
Regression from per-session points file change (1feb2ef): the service
returns START_STICKY, so when the OS kills it during screen-off, it
restarts with a null intent and onStartCommand minted a NEW points file,
repointing gps_live_points.jsonl and orphaning accumulated background
points. Evidence: many tiny orphaned gps_points_*.jsonl fragments.
Fix: onStartCommand creates a new session file only on a genuine start
from JS (intent with extras). A START_STICKY restart (null intent) keeps
writing to the existing session file from the pointer — one file per
session until Stop.
Verified on device: am kill (= START_STICKY restart) no longer creates
a new file, pointer unchanged, trail resumes on return. Background
writing confirmed: 49 points in 70s with screen off (Dozing) at 1Hz.
Compass:
- Gimbal lock compensation: when phone tilts past horizontal (|beta|>90
in landscape, |gamma|>90 in portrait), heading flips 180 — compensated
- EMA smoothing for heading (factor 0.3, ~300ms settle) — reduces jitter
from road bumps while keeping responsive turns
- 3 orient modes: X(off) A(auto) L(lock) — lock freezes layout, compass
still works with gimbal compensation
- Debug overlay on map shows alpha/beta/gamma/heading/mode
Build:
- ./build.sh install — install last APK without building
- ./build.sh -d install — install debug APK
- install_apk respects -d flag for debug/release selection
Products:
- health-diet.ru scraper (Tampermonkey) + import script
- 11469 products with 37 nutrients, Dodo 258, McDonalds 619, KFC 361, Ashan 2000
- Rust import_seed_products: dynamic column list, auto-create missing columns
- Seed version bumped to 10
GPS session safety:
- Separate gps_points_{ts}.jsonl per session, deleted only after DB save
- Toast on DB errors, NaN guard in finishGpsSession
Other:
- build.sh: router/VPS upload only with -u flag
- Orientation buttons bottom-right, weather via Yandex Pogoda
Settings:
- Aero drag (CdA), air density, pedal efficiency now in GPS config

- Saved to localStorage, used in computeStats
Bug fixes:
- Recipe detail: overlay.remove without popHandler cleanup → now uses history.back()
- weightKg parseFloat in startRecording and importGPX (string "88" bug)
