- rain radar layer: pure-Rust KNMI HDF5 reader (superblock v0 walk,
single-chunk deflate datasets, byte-exact vs h5py), ellipsoidal polar
stereographic reprojection (20 m vs product corners), bilinear value
sampling -> smooth banded isolines, textured quad overlay through the
overlay camera, 25-frame nowcast animation; RadarSync polls at most
once per 4 min through a disk-persisted gate and caches frames on disk
- makepad-geodata + makepad-tesla crates join the workspace (overlay
builders, radar sync, NL open-data layers; transit routes now z7-14)
- Europe major-roads routing graph: nav-build --major-roads does a
ways-first scan (5.7M ways / 46M nodes / 194 s / 971 MB) and the app
falls back to it when a route leaves the regional graph — Amsterdam to
Paris routes offline (501.8 km)
- 3D flying markers: chargers/POIs/stops ride thin stalks with DYNAMIC
height (each pin clears its own building +8 m); labels, kW text,
brand and tap zones all consume the baked per-marker lift; stalks and
buildings grow together on the 2D->3D transition (per-tile flat->3D
fade heights, no replay on zoom regens)
- markers depth-honest (small bias, buildings occlude them); phong-lit
canopy/light spheres matching the buildings' NW sun; buildings tint by
BAG age in 3D; district area tints (rank 60, alpha .32); transit line
labels + stop names; follow-mode is an explicit attach/detach toggle;
rotation release schedules the label re-place (no stuck upside-down
labels after a fast spin)

- Tesla-style droplet pins anchored at the tail tip (rotate around the
exact site point in tilted views); red exclusively Tesla, amber DC,
blue AC; Tesla pins show stall count, others peak kW
- in-pin text through the normal text renderer: billboard-anchored
glyphs (anchor scales with the map, glyph size constant), exempt from
label collision/repeat culling, no halo
- upright camera-delta labels: straightened labels (place names, POIs,
brands, pin text) translate with the rotation gesture but stay
horizontal — no more rotate-then-snap on regen
- per-icon zoom floors baked in vertex param4 + live icon_zoom uniform:
stale deeper-bucket tiles never flash markers on zoom-out (param4 is
lift-height only for non-icon shapes — icons stay on the ground)
- motorway exit labels (street_labels_points): carto-red name + ref
- 2D/3D mode: tilt gesture syncs app state (TiltChanged action), tilt
release near-flat settles to exact 0, mode flip re-bakes tiles
(extrusions appear/disappear without a zoom nudge)
- Simple 3D Buildings: building:part volumes with min_height bases;
outlines containing parts flatten to footprints; famous buildings
with tourism=attraction extrude instead of dying as attraction fills
- little 3D trees in tilt mode: crossed trunk quads + sphere-slice
ball canopy (architecture-model proportions)
- searchdb/mbtiles support work: reach-based distance ranking, direct
tile lookup + writer ordering

Relations reference ways randomly across the extract; the 128-group
WayStore LRU crawled Europe's pass 4 at ~260 relations/s (5+ hours).
Now: FlatWayStore decodes the whole relation-member way store into RAM
next to FlatNodeStore, assembler workers resolve and prepare features
(new prepare_point completes the set), a single writer owns the spool,
and the ordered consumer only parses members/tags. NH pass 4 3.9s ->
1.3s, per-layer feature counts identical.

Projected grid values are <= 2^26 at zoom 14, so i32 is exact; decode
hard-errors on out-of-range rather than ever truncating (no swimming
roads). NH output identical feature counts.

Europe's ways arrive in creation order, i.e. spatially random: any node
cache that fits in a fraction of the store loses. The store is only
13.8GB compressed, so FlatNodeStore decodes ALL of it once (parallel,
~a minute for Europe) and resolver workers share it lock-free via Arc —
no cache, no eviction, no zlib on the hot path. NH pass 3: 5.6s -> 3.5s;
feature counts unchanged.

- NodeStore eviction was a min_by_key scan of the whole cache per miss;
with the Europe-sized cache that scan became the bottleneck (1.2k
ways/s). FIFO queue eviction is O(1) amortized
- way resolution now fans out over a resolver worker pool (each with
its own NodeStore handle and cache slice); geometry is localized on
the workers via prepare_lines/prepare_polygons and a single writer
thread owns the spool, so the on-disk format is untouched. The
id-ordered relation-way store stays on the ordered consumer thread
- Noord-Holland: pass 3 32.6s -> 5.6s, full conversion 25.7s; per-layer
feature counts identical (byte diff is record interleave order only)

Two fixes to the detail converter that spent 10+ hours on Europe:
- visit_pbf: ordered parallel decode — blob reads stay serial, the
zlib+protobuf decode fans out over a worker pool, and the callback
runs in exact file order on the calling thread, so id-ordered store
builders need no changes
- NodeStore group cache: 256 groups (128MB) thrashed on Europe-scale
way resolution (~115us/way of cache-miss zlib re-decode, ~8.6k
ways/s); now MAKEPAD_NODE_CACHE_MIB (default 8GB), way resolution
~370k/s
Noord-Holland: 61s end-to-end, output byte-identical to the slow
converter (7547 tiles, same bytes).

- Hella Haasseplein root cause: pedestrian squares in osm_lines arrive
as LineStrings, so `closed` was never set and the area admission
skipped them — detect implicit closure (first==last) and mark the
ring closed for the fill pass
- icon collision: doors and generic dots now yield to real symbols
(the recycling icon was losing to the building entrance beside it);
entrances gate at z18 like carto
- tools: tagprobe <pbf> <name> — dump every OSM element matching a
name, for answering "how is this actually tagged" without overpass

score_search_hit: settlements are near-immune to distance ("brussels"
from Amsterdam means Bruxelles, not the closest Brusselsestraat),
POIs/streets keep strong local bias, and a number token signals
address intent. nav-build --places-only scans a pbf for settlement
nodes into a compact index (Europe: 1.31M places, 67MB, 60s); the app
merges it with the regional full index, deduping same-name near hits.
Route overlay decimation now measures against the last drawn point,
bounding the error at ~1.5px — pairwise skipping compounded and
visibly reshaped the route when zoomed out.

Conversion tooling (tools/map_tiles): curated Shortbread base pyramid
from a VersaTiles planet archive (bbox extract, brotli->gzip transcode
parallelized per 256x256 block), all-tag native OSM pbf detail
converter, pbf audit, and nav-build/nav-probe producing the routing
graph + search index artifacts. download_map.sh orchestrates pinned
downloads and conversions. mbtile_reader writer now skips SQLite's
lock-byte page at byte offset 1 GiB — allocating through it corrupted
every database over 1 GiB ("2nd reference to page 16385"); the 31 GB
Europe conversion passes integrity checks.
Navigation (libs/map_nav, new): region.search place/POI/street/address
index (prefix autocomplete, NL/EN category synonyms, proximity
ranking) and region.graph routing graph (CSR directed edges,
car/bike/foot speeds, oneway, turn restrictions, snap grid, A*),
maneuver generation and the NavSession map-matching state machine;
26 unit tests.
MapView interaction layer: MapViewAction, camera API + animated
fly_to, overlay.rs (route polyline with traveled dimming, markers,
position puck), per-widget mbtiles_path override, archive
minzoom/maxzoom honored for tile requests, zoom-level cross-fade over
the previous level's imagery, floating panels win hit-testing.
examples/map is the navigator app: worker-thread search, Drive/Bike/
Walk routing, simulated turn-by-turn with banner, follow camera.
