Texture-mode passes append to one retained command buffer flushed at the
window pass (safety flush at repaint start for texture-only frames) —
the 12-pass gauss pyramid paid ~1ms commit/schedule latency PER PASS.
Profiling mode (MAKEPAD_GPU_PROFILE) keeps per-pass buffers so spans
stay attributable. Startup window 3400x2050 for pixel-heavy iteration.

Post-build O(n) partition on the per-vertex zoom-floor slot; pass 4 draws
the band only at view >= 16.25. Kills millions of shader-collapsed icon
verts per frame at mid zooms.

Per command buffer: pass debug name, GPU start->end interval, draw calls,
vertices, instances, upload bytes — accumulated and printed as a 1Hz
table from the completion threads. Map frame stats gain gpu_ms/gpu_max
from the existing PERF_CHANNEL_GPU ring.

Europe re-cut with these buckets happens on explicit go; the NL cut
lives in local/maps (untracked) for cross-session stability.

The cache-hit path re-emitted every glyph CPU-side with the pan shift
baked into vertices; under tilt that visibly trailed the tile geometry
(which pans purely by uniform). The pan/zoom delta now rides two new
uniforms applied before the existing camera-delta matrix, in the same
frame as map_offset — labels physically cannot lag the map. Pin-interior
text keeps constant px via a billboard instance flag.

Pinned carriers stretched the 1px AA band into a wide smear at corr>1 —
the dirty road edges across the morph band.
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
At the keyframe corr==1 cancels offsets entirely, so ring-circular 1-2-1
smoothing (3 passes) costs zero keyframe fidelity; mid-morph the edge no
longer saw-tooths where junction wrap-arounds swing miter direction
per vertex.

The deck-shadow dissolve ran after the bake sink's early return, so no
cut ever contained it and every dz-covered street tile paid ~59ms at
runtime (found via emit-section fencing: ebuild=59). Extracted
dissolve_deck_shadows; the sink concatenates it into the baked shadow
shapes (concat == today's two separate emits exactly); a shadow HIT now
gates the runtime block off. Also: face-arm/stroke-arm/events laps, icon
template cache, batched expanded writer.

subdivide_face_mesh_morph carries the offset channel (midpoints average
endpoints); decked bodies emit via the expanded layout with per-vertex
deck override. Fixes the magnified-wide roads across bridge-dz coverage
(all central Amsterdam) at deep zoom.

Street trees memcpy one origin-built mesh (anchor+zbias patch); icon
stalk clearance queries a building-ring cell grid instead of scanning
icons x groups x rings. Worst AMS 368 -> ~310ms serial.

The icon matchers read a finite key set; parsing micro-POI layers with
the whitelist off was ~140ms/tile at kf16. Worst AMS 504 -> 368ms serial.

Icon-horizon tiles run 50-85MB; a fixed 1.2GB budget sat below
visible+pan-ring at street zoom and pure LRU evicted the very neighbors
a circling pan re-enters — every loop around a center rebuilt its ring.
Budget now grows to hold 2x the visible set and eviction orders by
distance from the view center (LRU only as tiebreak): the ring survives,
the trail is what dies.

Morphable (flat, opaque, non-emissive) face bodies+fringes emit through
append_expanded_stroke_geometry (anchor = pos - miter*hw_key): the live
zoom re-widths them per frame via the existing width_correction path, and
the expanded branch already zeroes the fragment params faces with glow
would need — those stay pinned. render_bucket collapses to keyframes
{<=14 native, 15->14, >=16 -> 16}; icons include to a z18 horizon from
the high keyframe and reveal via the live icon_zoom uniform (mechanism
existed). Existing v3 streams serve both keyframes unchanged — the only
restyle event left on the zoom axis is the single 14<->16 crossover.

build_paint_faces maps every outline vertex's exact f32 coords to its
miter normal and emits offsets (normal x keyframe half-width) parallel to
body and fringe verts; junction blends, clip cuts, carrier outer edges
and translucent groups pin at zero.

BakedFacesBucket v3 carries the dissolved shadow shapes + grounded
footprints under their own input signature (job rings/heights, sun,
scale, min-edge); the runtime shadow block on a HIT skips
sweep/dissolve/diff/open wholesale and tessellates the baked shapes
(b-sh-baked 0.5ms vs 0.2-2.6s). bake_tile_paint_faces now builds 3D so
the shadow pass runs at bake time; faces signatures are road-only and
stay valid. Night/dynamic-sun themes gate at bake_shadows and simply
never submit the shapes. Theme-independence test passes on v3; NL smoke:
8418/5388 2.7s -> 97ms, 8417/5387 1.6s -> 134ms, worst AMS rz16 258ms
honest (was 611ms with runtime shadows).

The headless probe theme ran with bake_shadows OFF while every app theme
runs it ON, so all headless profiles silently skipped the shadow pass —
'155ms worst tile' excluded the 0.2-2.6s shadow dissolve the app pays
(user's 1.6-3.1s dockland tiles reproduce exactly now). Probe now bakes
shadows; b-jobs/b-sh-sweep/-dissolve/-diff/-open laps split the stage.
Buildings-buffer pre-reservation REVERTED (first-touch of ~240MB zero
pages per builder serialized 12 workers on the kernel fault path: 340ms
-> 3000ms in-app). Minkowski-sweep shadow silhouette tried and REVERTED
(epsilon-concave rings hand i_overlay self-crossing polygons, 10-15s;
also: f32-grid arithmetic in shadow geometry is load-bearing — f64-exact
translated points changed boolean coincidences and tripled dissolve
time). Real fix queued: bake dissolved shadow shapes per bucket.

libs/mbtile_reader gains the .mkmap consumer: root.mkidx parse (Hilbert
tile ids, root ranges -> brotli leaf directories -> shard/offset/len),
positioned shard reads, same get_metadata/get_tile_decoded surface as
MbtilesReader; TileArchiveReader sniffs the path so mbtiles_path can
point at either. Index format v2 drops JSON: the metadata section is now
varint KV like the leaves (writer + reader; no serde in the container).
Loader, zoom-range probe and the headless harness go through the enum;
bridge-dz/overlay sidecars stay mbtiles. Harness parity via shards:
worst AMS rz16 164.7ms, z12 native 51.3ms — identical to mbtiles. App
repointed to local/maps/europe-base-br.mkmap (111 shards + root.mkidx,
the exact bytes a CDN would serve).

In-app at z15 every tile ran the 460ms runtime cascade (buckets were
14+16 only); NL smoke: worst rz15 key 600 -> 53ms. Europe final cut
rerunning with 14,15,16.

Road-surface tier identity (RoadSurfaceKey) now carries a theme-stable
class id (fnv of the styling rule's kind) plus geometric fields instead of
resolved colors; identically-styled rules alias to one canonical id at
theme compile so kinds a theme paints the same still union as one tier.
Plaza grouping keys on alpha alone (road-polygon fills are one theme
constant). The bake input signature contains no colors, so recolor-only
themes (night, circuit city — user contract: themes only recolor, shadows
fade via alpha) share one baked stream: proven by
baked_faces_theme_independent (5 keys, identical signatures + regions
under a full recolor via probe_compiled_theme_recolored). Light output:
fills byte-equal, casing within 0.3% (same-rank painter tiebreak moved
from color values to class ids — visual check pending).

The bake guard now hashes the ring-construction INPUT (tier order/styles,
smoothed way points+dz, plaza rings, joint/portal end sets, clip) with a
deterministic FNV std-Hasher instead of hashing the constructed rings, so
a HIT skips road_ribbon_rings + per-ring field classification wholesale:
rings+fields 35.7 -> 0.8ms, worst AMS rz16 3D 224 -> 155ms (NL v2 bake,
byte-equal buffers vs the runtime cascade kill switch). BAKED_FACES_VERSION
2 rejects v1 streams (old semantic) into the safe fallback. Also: part-
centroid cell grid for the building cover test (buildings 25.5 -> 13.6ms,
Paris was 56ms), lookup-only cell maps switch SipHash for a multiply-rotate
hasher (DzField::sample), VisibleRegions: Clone for the OOB-region guard.

Replaces the remaining linear bbox scans in grade-through/flush-ends with
a 16-unit cell grid (candidates stay in ascending way order, so
first-match semantics survive); append helpers now extend_from_slice one
19-float record with reserved capacity. 7-tile rz16 sweep + z12 byte-equal.

The zoom-out pyramid was never baked: z11-13 city tiles ran the full
painter cascade at runtime (z12 AMS 340ms cascade, 661ms build). map_bake
gains --zooms (native bucket below z14) and the renderer accepts baked
buckets 10-16; NL smoke bake: 861 tiles/55MB/31s, z13 166->19ms,
z11 252->28ms. Remaining z12 cost was two quadratic endpoint passes over
4017 join ways: bbox+reach prefilters and an endpoint hash grid cut
grade-through 103->33ms and flush-ends 98->3ms, bit-identical (every gate
is half-width-bounded; buffer sizes byte-equal across the sweep). Also
sp-* sub-laps in stroke-prep.

Deck matching was O(verts x corridor segments) per stroke (84ms on the
worst AMS tile): per-tile CorridorGrid + mirrored-pair reuse cut it to
4ms, bit-identical (MAKEPAD_CORRIDOR_VERIFY oracle, MAKEPAD_CORRIDOR_BRUTE
fallback). Detail-merge parsed all six osm_* layers with full tags
(~110ms/tile constant): per-geometry-class layer skip + tag-key whitelist
below icon zooms cut it to 28-40ms; whitelist audited against style.rs
readers ('tunnel' omission flipped Paris plaza rings and MISSed the baked
cascade — CASCADE-GROUP dump + 7-tile size-parity sweep now guard it).
Full-build stage laps (payload/baked/dz/mvt-parse/detail-merge) close the
former ~110ms accounting gap; MAKEPAD_TILE_HASH prints a buffer fnv.

Overnight run 2026-08-01: 9,380,390 tiles z2-14 in 3.2h, faces bake 1h
(+8GB, worker-side brotli q10), transmux to 99 shards all <510MB.
App repointed to europe-base-br-faces.mbtiles. nl-bridge-dz verified
byte-identical against the new base (deterministic feature indices).

- The boolean union cascade (59-77% of heavy tile builds) is now baked
per (tile, bucket 14/15/16) as additive field 101: cascade output made
deterministic (1/64 grid snap, canonical ring order, sorted tiers) and
bit-reproducible; renderer consumes guarded by structure signature +
coordinate checksum with runtime fallback; MAKEPAD_NO_BAKED_FACES=1.
Roundtrip bit-identical on all keys x buckets x dz configs. New
tools/map_bake producer (worker-pool incl. worker-side brotli).
- z14 streets merging never ran (early-out at DETAIL_ZOOM): fixed —
1957->1285 ways (-34%), payload -20MB, cascade input shrunk at source.
- Slow-tile log now prints per-stage ms + a ready-to-paste headless repro
command; harness honors archive/detail/dz/overlay/rz/3D envs.
- Worst AMS tile: 2-3s cold -> 175ms rz16 (61ms native); NL bake data
882MB at 60ms threshold; Europe needs threshold 150ms + 2 buckets to
fit shard budget (+2-4GB est).
- App -> nl-base-br3-faces archive; bridge-dz rebake required (joins
fail closed against br3 feature indices).

The stale-bucket result drop compared buffers.render_zoom (request-zoom
space, clamped to the archive max) against render_bucket() (unclamped):
never equal at overzoom, so EVERY completed tile at building zooms was
discarded, re-requested and discarded again — one-tile viewport, stuck
queues. Stale-bucket results are drawable; the bucket-restyle path
rebuilds them properly.
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
- Regression attributed: the combined archive's six osm_* detail layers
were wholesale-ingested and STYLED by the base parse (roads double-
styled via streets + osm_lines: union input 946->3940 rings, stroke
prep 26x) -> 2.1-5.5x slower than the old two-archive pair. Layer-level
lazy skip (MvtSink::wants_layer): unconsumed layers skip as raw bytes
in both passes; all 24 profile cells improve 1.3-2.3x.
- Gray-tile keep-stale: three kill paths fixed — mark_tile_failed no
longer replaces drawable Ready entries with gray placeholders on batch
errors (archive rewrites), transient absent reads no longer evict
Ready meshes + 30s blacklist, retry backoff moved to TileEntry.
- Tilt-aware request priority (camera-projected screen distance with
toward-camera bias) — the near field builds first under tilt.
- Restyle bursts lift the 4-slot gesture throttle to 12; queued jobs for
dead zoom/bucket/mode are pruned (TagThreadPool::retain_queued), stale
results dropped pre-upload; uploads byte-budgeted (24MB/frame).
- Stage matrix: painter-order union cascade = 59-77% of every cell
(~320-350ms worst key) — per-bucket face bake is the path to <200ms.
- Baked-fill strips: A/B shows no measurable win post fill-tessellator
optimization -> removal recommended (dissolve stays).
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
- Sign probe was 57-76% of z9/z13 fill cost (point_in_fill_rule scans all
contours per probe): exact bbox prefilter (always on, bit-identical) +
trusted-winding map-only mode (holes take the exterior's sign; bowties
and orphan slivers keep the probe). Sweep rework: persistent zero-alloc
tessellator, events sorted once + cursor (BinaryHeap::pop was 40% of
fill CPU), ~V events instead of 2V, direct index output. 4.4-7x per
tile, worst per-fill 42.9ms -> 4.5ms, 6798/6798 fixture fills
bit-identical in both modes. MAKEPAD_TESS_DUMP fixture capture +
fixture_bench with per-stage split.
- Baked-fill fast path (v2-fills-1, flat mode): field-100 strip decode,
per-triangle Sutherland-Hodgman clip to the fill overlap rect, edge AA
via new Tessellator::fill_fringe_into over the deduped rings; 5% area
guard falls back to runtime tess — and caught a real emitter bug
(inverted ring winding on z13 water would have erased a water body).
MAKEPAD_NO_BAKED_FILLS=1 kill switch; baked_fill_audit headless test.
