# Changelog
+## 4.0.0
+
+### Major Changes
+
+- Make Policy Runner HTTP server mode compact by default through protocol version `2`. `/policy/reset` receives static specs and configuration once, while each `/policy/decide-batch` request sends compact vectors, previous actions, metrics, and events instead of repeating rich observation objects, schemas, snapshots, or track metadata.
+
+### Performance And Runtime
+
+- Rework the race-step phase order so normal active steps perform one authoritative broad race-state commit per simulation step, while pre-physics work reads the previous committed state.
+- Make the normal active-step broad commit consume the already-refreshed post-motion wheel/track state instead of recomputing wheel-surface classification a second time for every car.
+- Derive broad-commit DRS reference cars from one physical-track-order pass instead of re-scanning the full field for every car during the same commit.
+- Keep the common no-DNF full-field DRS reference build on the already-ordered race field and write references straight into the reused indexed buffer, so the benchmark broad-commit path avoids rebuilding a second live-car list before the same ordered-forward reference walk.
+- Keep DRS latch updates on cached active-zone references and in-place detection records instead of repeatedly re-finding the same zone by id and rebuilding the detection object shape on every broad-commit latch update.
+- Cache the next DRS detection-zone index on each car across steady forward motion, so broad-commit DRS latch updates stop rescanning the whole DRS-zone list on the common path while external car-state jumps still invalidate the cache safely.
+- Add a narrower cached-next-zone no-crossing fast path inside broad-commit DRS latch updates, and enforce it with direct unit coverage plus runtime benchmark counters so the dominant steady-forward unlatched case stays off the generic wrap-aware crossing math.
+- Keep the broad-commit DRS latch path on a sim-bound scalar call instead of rebuilding the same options object for every car on every step.
+- Keep the common no-finish race-end check on one direct ordered-field pass, so broad commits stop allocating a temporary finished-car list and then rescanning the same field again just to prove the race is still running.
+- Reuse lap-telemetry sector arrays and sector-performance buffers in place during broad race-state commits, removing per-step short-lived timing allocations without changing the public telemetry shape.
+- Keep lap-telemetry position refresh in place during broad commits, so normal per-car telemetry updates stop allocating a temporary lap/sector position object before rewriting the same fields back onto `lapTelemetry`.
+- Keep the common no-boundary lap-telemetry path on a narrower in-progress sync that updates only live scalars plus the active-sector slots, instead of re-synchronizing the whole three-sector position structure on every committed step.
+- Dirty-gate broad-commit sector-performance classification so unchanged current/last/best sector buffers keep their existing `lapTelemetry.sectorPerformance` arrays instead of rebuilding the whole field classification on every committed step.
+- Reduce browser/runtime churn by keeping full public snapshots for host/debug/export/full-state APIs while using lean render, training, and transport paths for hot loops.
+- Keep Policy Runner diagnostic JSON throttled so automatic playback does not stringify the debug readout every frame.
+- Keep more driver-precision road-edge, kerb, and illegal-surface rays on the direct indexed ray-band path, including validated off-track recovery boundaries, and resolve ambiguous recovery, pit-connector, and pit-lane-origin rays through one bounded sampled pass inside the ray-band tracer instead of separate road/surface fallback scans.
+- Keep diagnostic `debug` precision inside the same ray-band tracer, including refined sampled recovery for pit-connector and other ambiguous diagnostic rays, so debug ray builds no longer escape to the legacy separate road/surface scans unless the track index is unavailable.
+- Keep common main-road illegal-surface direct rays on tracer-owned post-kerb band classification instead of re-running generic nearest-track validation at the outer kerb boundary, so validated direct sensor-ray paths cut their remaining classification queries without reopening the sampled-recovery cases.
+- Rebuild direct sensor-ray origin state from same-pose main-road `progress`/`signedOffset` geometry when that pose already matches the live ray origin, so the runtime sensor-ray benchmark stays on its direct boundary-validation work instead of paying an extra nearest-track origin lookup on every iteration.
+- Let batch-training surface rays use the same ray-band tracer as normal driver rays, with a main-track-only connector mode and scratch-owned tracer result/surface-boundary containers, so kerb/illegal-surface-only batches stay on reusable direct indexed geometry with `nearestQueries: 0` and no per-ray tracer result replacement.
+- Anchor direct sensor-ray boundary validation on the exact ray-hit boundary segment neighborhood instead of a generic nearest-track classification lookup, so the benchmark direct path keeps all `320` rays fully direct with `nearestQueries: 0` while generated-track validation still agrees with sampled characterization.
+- Reuse the already-known main-road origin classification on direct sensor-ray boundary validation, so main-road direct rays validate the outside boundary sample only and the benchmark direct path drops from two indexed boundary-neighborhood queries per ray to one without reopening sampled recovery or generic nearest-track fallbacks.
+- Keep barrier-origin direct illegal-surface boundary validation on the exact ray-hit segment neighborhood instead of falling back to generic nearest-track classification for those three boundary samples, and pin that path with a dedicated runtime benchmark that must stay fully direct with `nearestQueries: 0` and `segmentNeighborhoodQueries: rayCount * 3`.
+- Keep barrier-origin off-track recovery rays on direct indexed band classification whenever the tracer already proves road-edge/kerb misses and the first non-barrier illegal-surface entry, so that recovery route no longer drops into the sampled local-marching path just to confirm the same result.
+- Keep direct sensor-ray boundary tracing on reusable segment-id scans and centerline typed arrays instead of materializing temporary track segment objects, and pin zero ray segment object allocations in the runtime benchmark contract.
+- Keep indexed sensor-ray boundary tracing on tracer-owned reusable offset, distance, segment-id, and boundary-result containers in the per-ray scratch query, and enforce that direct sensor rays reuse those containers in the runtime benchmark contract.
+- Keep indexed sensor-ray grid traversal on one query-scratch sample point instead of allocating a temporary `{ x, y }` point per ray-grid step, and enforce that sample-point reuse in the runtime benchmark contract.
+- Keep sensor-ray channel selection on reusable scalar channel flags in the per-ray shared query instead of allocating `Set` containers or using filter/spread min helpers on the hot tracer path, and enforce zero channel-set allocations plus stable channel-flag containers in the runtime benchmark contract.
+- Resolve pit-lane-origin side rays directly from the pit-road normal/width geometry when the current pit-lane frame proves the boundary hit, so common pit transition rays avoid sampled nearest-track classification entirely while retaining bounded sampled recovery for ambiguous pit rays.
+- Keep pit-route transitions on route-owned scalar segment cursors, reusable stop sample points, and reusable route-projection scratch instead of allocating sampled route points or projection objects during entry, queue-release, and exit movement, and add a required runtime benchmark category that fails on sample allocations or cursor fallback scans.
+- Keep indexed pit-road state projection on reusable polyline projection plus index-owned route distance tables instead of rebuilding candidate sets, filtered segment arrays, or cumulative distance arrays for each entry/fast-lane/working-lane/exit classification, and extend the track-query benchmark with explicit pit-road probes that require grid hits, scratch reuse, precomputed route distances, zero cumulative-distance rebuilds, zero grid misses, and zero pit fallbacks.
+- Keep scratch-backed rich sensor rays on stable road-edge, kerb, illegal-surface, and car-hit channel containers across repeated direct builds, while public no-scratch ray calls still receive fresh channel objects.
+- Keep car-ray exact footprint checks on the caller-owned ray vector and scalar local footprint math, writing scratch-backed hits into reusable per-ray result targets and pinning zero car-ray vector recomputes in the sensor-ray runtime benchmark.
+- Reuse scratch-backed ray-detectable target arrays and target wrappers across vector-only environment ray batches, so car-ray broadphase stops rebuilding target metadata containers while public no-scratch sensor calls keep fresh target arrays.
+- Keep scratch-backed per-car ray target filtering on one stable filtered-target container and scalar write/count loops, so the car-ray path stops rebuilding callback-driven target lists before each ray batch and the runtime benchmark now fails if that filtered container is replaced.
+- Cache normalized ray options inside scratch-backed ray batches and scalarize ray-option normalization loops, so repeated raw ray option objects no longer rebuild normalized ray/channel arrays before every rich/vector/append sensor pass.
+- Reuse headless environment observation lookup scratch for controlled-driver car maps and no-event grouping, so vector-only training steps stop rebuilding those lookup containers on every result while public observation shapes stay unchanged.
+- Reuse headless environment metric lookup scratch for previous/current car maps and contact-event driver grouping, so vector-only training steps stop rebuilding those metric containers on every result while contact counts still dedupe duplicate driver ids per event.
+- Precompute the nearest nonlocal segment distance for each track segment through the kerb band and let hinted nearest-track queries trust local segment neighborhoods only when the current offset is geometrically provable, so centerline/near-center common paths avoid extra exact-grid refinement while close-loop and generated-track cases stay on the more defensive indexed path.
+- Precompute ring-1 segment-neighborhood density per track-query cell and let low-density `track/kerb` hinted nearest-track queries trust their exact local segment neighborhood even when the nonlocal distance proof stays inconclusive, so the benchmark nearest-track path keeps the benchmark track on local geometry instead of dropping into exact-grid refinement while denser generated-track cells stay on the defensive path.
+- Precompute exact ring-1 candidate segment neighborhoods for low-density query cells and let hinted gravel-adjacent nearest-track queries prove exactness by ring-2 lower bounds before falling into the full exact-grid walk, so the benchmark nearest-track path keeps most remaining gravel queries off the broader cell-search loop while denser or more ambiguous cells still fall back to the original exact refinement.
+- Route low-density cell exact nearest-track queries through that grid-owned ring-2 proof before any arc-bucket prepass, so the benchmark gravel path no longer computes the radius-2 arc candidate window just to hand off to the same certified cell-neighborhood winner.
+- Route outside-runoff nearest-track queries through the sparse exact segment-grid walk before arc buckets, so far-out recovery and destroyed-car classifications use the grid-owned exact proof directly instead of seeding the same exact result through a radius-2 arc candidate prepass.
+- Keep benchmark-style runoff nearest-track queries on an exact radius-2 segment-neighborhood proof guarded by ring-3 cell lower bounds, and seed the fallback exact-grid walk from that same local winner when the proof does not close, so the remaining hinted runoff path avoids repeating inner-cell work while generated-track equivalence stays covered.
+- Start exact-grid nearest-track refinement at the first occupied segment-grid ring instead of rescanning known-empty inner rings, so far-off accurate-hint queries skip empty-cell work before they reach real track geometry while preserving the same exact winner.
+- Skip recomputing the already-seeded hinted winner segment when exact-grid nearest-track refinement starts from an initial local projection, so hinted off-track exact checks spend less time re-evaluating the same segment before scanning genuinely competing cells.
+- Precompute the common radius-2 arc-bucket segment neighborhoods at track-query index build time and reuse those candidate lists on hinted arc lookups, so the dominant remaining arc-hint nearest-query path stops rebuilding and re-deduping the same five-bucket candidate window on every query.
+- Precompute immutable centerline projection scalars per segment and reuse them across exact-grid, arc-bucket, candidate, and neighborhood track-query loops, so hot nearest-track projection paths stop rebuilding the same `dx`/`dy`/length-span math on every segment visit.
+- Cache repeated progress-hint segment resolution and hint-point reconstruction across adjacent same-distance nearest-track queries, so the indexed hinted path stops repeating the same binary-search and hint-point reconstruction work for each offset around the same centerline sample.
+- Replace the blanket pit-connector wheel-surface fallback with per-wheel connector geometry plus tighter exact local segment-neighborhood wheel-center projections for the real connector cases, batch those exact wheel-center neighborhood queries across all four wheels, skip pit-lane override work when main-track precedence already settles the wheel, and skip pit-box grid scans outside service/garage bounds, so the benchmark connector pose keeps its one-nearest-query-per-iteration shape, no longer wastes pit-box misses, and connector wheel-center queries stop rebuilding the broader default neighborhood separately for each wheel.
+- Route direct `calculateWheelSurfaceState()` calls through the same scalar wheel-state writers used by the scratch-backed apply path, removing the public-path `map()`/patch-sample fallback arrays and adding a wheel-surface benchmark gate for scratchless scalar writer batches and per-wheel writes.
+- Make exact local segment-neighborhood batch queries scan the shared neighborhood once for all requested wheel centers instead of rerunning the same exact neighborhood walk per wheel, so connector local-refresh path queries reuse segment data without changing exactness.
+- Skip pit-lane override index work for nearest-track queries already proven to be on the main road and outside pit-box bounds, so connector-adjacent common-path track classification stays on the geometry result instead of paying unnecessary pit road/box candidate scans.
+- Keep connector-adjacent pit-entry/pit-exit nearest-track classification on indexed endpoint-window road candidates keyed by track-progress hints, so the track-query benchmark no longer drops those valid cap projections onto the full pit-road polyline fallback after a road-grid miss.
+- Resolve connector-adjacent pit-entry/pit-exit overrides and adjacent non-pit gravel/runoff skips directly from exact local pit-road geometry before the indexed pit-lane query path, so the benchmark track-query route keeps the remaining connector cases off pit-road grid work entirely while preserving the same pit-lane classification.
+- Keep those direct connector pit-road projections on the query-index-owned reusable projection target and route-distance metadata, and extend the runtime track-query benchmark so direct connector state/skip coverage must also prove projection scratch reuse.
+- Precompute pit-route endpoint segment windows and use bounded direct connector projection candidates instead of scanning full pit-entry/pit-exit polylines in connector shortcut paths, while mid-connector points without endpoint progress hints use indexed route candidates without counting as full pit-lane queries.
+- Keep hinted nearest-track projections on a direct hinted-segment neighborhood through the main-road, kerb, and gravel bands, and resolve the remaining wide-runoff cases through one wider same-neighborhood segment-radius search instead of spending the extra local segment-grid refinement on the benchmark path.
+- Precompute the wrapped segment-id neighborhoods for the dominant radius-2 and wide-runoff hinted nearest-track searches, so those hot local hinted paths stop rebuilding the same wrapped modulo walk on every query.
+- Keep hinted and exact local segment-neighborhood track projections on direct wrapped segment loops instead of materializing temporary neighborhood id arrays first, and pin zero hinted-neighborhood id scratch materialization in the runtime benchmark contract.
+- Keep nearest-track exact-grid, arc-bucket, and candidate scans on scalar candidate accumulation instead of allocating transient per-segment projection objects during the hot indexed query path, and pin zero candidate projection object allocations in the runtime benchmark contract.
+- Reuse one internal nearest-track projection scratch object through `nearestTrackState()` while keeping the public nearest-track projection query fresh per call, and pin that reuse in the runtime benchmark contract so the hot indexed track-state path stops rebuilding the same transient projection container.
+- Keep connector local-refresh wheel-surface handling on exact wheel-center projections alone when every exact wheel center still resolves to the main track, so that route avoids materializing redundant finalized connector queried track-state pools before falling straight back to analytic wheel-state handling.
+- Keep the explicit-center connector local-refresh path on a one-pass analytic summary whenever the exact batched wheel-center neighborhood queries all stay on the main track, and add a dedicated runtime benchmark for that explicit-center route so post-runoff wheel-surface work is measured against the same path the sim actually uses during local refresh.
+- Refresh automatic connector-adjacent wheel-surface center state through the existing local runoff-track fast path instead of a broad nearest-track query when a previous committed track state already exists, and pin zero nearest queries for the near-pit connector benchmark path in the runtime benchmark contract.
+- Reuse the already-committed current-pose `car.trackState` directly on same-pose automatic connector-adjacent wheel-surface refreshes, so the near-pit connector benchmark no longer spends a fifth local segment-neighborhood query just to re-derive the already-valid center state.
+- Prove straight connector-adjacent main-track wheel footprints analytically from the center track frame before running exact wheel-center neighborhood projections, so centered pit-straight connector local-refresh paths stay on reusable analytic wheel writes with `segmentNeighborhoodQueries: 0` and `segmentNeighborhoodBatchCalls: 0` while ambiguous pit-side wheels still use the exact connector geometry path.
+- Thread the already-resolved current vehicle geometry straight through wheel-surface recomputes and delay connector sample-closure creation until the path actually needs sampled recovery, so common local-refresh wheel-surface work stops paying duplicate current-geometry reads and unused connector closures.
+- Add a strict common-case wheel-surface fast path for cars whose center state is still on the main track and not near a pit connector, so the dominant local-refresh path returns directly from the analytic main-track branch instead of walking the pit/connector decision tree before landing on the same result.
+- Make exact local segment-neighborhood projections write their final result into reusable target objects instead of allocating a fresh projection object for every connector/runoff exact query, and enforce that reuse on the connector wheel-surface benchmarks.
+- Keep the exact connector wheel-center batch path allocation-light by reusing the queried-state target array and reusable wheel-center point refs instead of allocating a fresh batched state array and copying the results back out on every local-surface refresh.
+- Skip connector wheel-center track queries entirely for connector-adjacent main-track cars whose full wheel footprint stays on the opposite half of the track from the pit-lane side, keeping those cars on the plain analytic wheel path and cutting the local-surface connector query volume back to the ambiguous cases only.
+- Replace per-step timing-history `shift()` trimming and timing-line key rescans with bounded lazy compaction and cached timing-line retention bounds, and add a warmed-history runtime benchmark so long-run timing maintenance stays production-ready.
+- Skip unchanged zero-travel timing-line maintenance once the retained-line prune cutoff is already current, so idle broad-commit timing updates stop rescanning stored crossing keys while still preserving the first prune/bounds catch-up pass.
+- Move runtime timing-history writes onto a fixed structured ring store, so broad race-state commits stop allocating a fresh `{ time, raceDistance }` object for every car on every timing sample while keeping legacy array readers valid for tests and older internal fixtures.
+- Cache the last successful structured timing-history interpolation neighborhood and probe it first on the next adjacent-gap lookup, so broad-commit interval timing stops rescanning the same timing-history window from the tail on every repeated follower-gap estimate.
+- Bound timing-gap timing-line scans to the overlapping stored line window shared by the compared cars, so broad race-state commits stop walking the full retained timing-line span when the latest shared crossing already proves the interval gap.
+- Skip timing-line gap scans entirely when either compared car has not stored a valid timing-line window yet, and enforce that empty-window fast path with a runtime benchmark that must perform zero timing-line crossing reads.
+- Skip the timing-line helper call entirely on the common empty-window gap-estimation path, so adjacent broad-commit gap checks fall straight back to timing-history interpolation without paying extra timing-line wrapper/setup work when no stored timing-line window exists.
+- Cache the last successful timing-history interpolation segment as direct distance/time scalars, so the common adjacent broad-commit gap path can reuse the same structured timing-history segment on nearby repeated targets instead of rebuilding the segment lookup from the offset cache every call.
+- Flatten Policy Runner protocol `2` per-decision JSON around `driverIds`, sending aligned vector arrays, compact previous-action tuples, and compact metric tuples while moving tuple field order into reset metadata, so HTTP policy-server mode spends less bandwidth and stringify time without reintroducing rich observation payloads.
+- Keep `car.trackState` and the wheel-surface cache wrapper stable across internal `applyWheelSurfaceState()` recomputes, so the exact post-physics local-refresh path stops replacing those hot-loop containers when only the track-state fields changed.
+- Replace per-call wheel-surface cache signature string building with direct geometry-pose and center-state field checks, so repeated explicit-center refreshes stay on the cache-hit path without avoidable string churn.
+- Split current-pose vehicle geometry reuse from swept-collision geometry reuse so pre-physics wheel-surface refreshes do not rebuild the same current wheel/body geometry just because `previousX`, `previousY`, and `previousHeading` were updated for collision history.
+- Update the cached current-pose vehicle geometry state in place when the car's live pose changes, so post-physics wheel-surface refreshes stop allocating a fresh current body/wheel/corner tree for every moved car on every step.
+- Keep the cached current-pose geometry writer on shared heading scalars and direct body/wheel rectangle writes, so post-motion local refresh no longer allocates temporary axis and center objects while rebuilding the stable geometry tree.
+- Keep current-pose wheel/body corners lazy inside the wheel-surface geometry cache, so normal post-motion refresh only rebuilds contact-patch centers, axes, and extents while sampled recovery paths still materialize and reuse exact corners on demand.
+- Drop unused string signature bookkeeping from the hot current-only vehicle-geometry cache, so post-motion local refresh stops rebuilding `x:y:heading` signature strings that runtime code never reads.
+- Collapse wheel-surface result summarization into one pass so effective surface, representative offset, and track-limits ownership no longer rescan the same four wheels with separate reductions on every refresh.
+- Keep scratch-backed wheel-surface classification on a reusable summary accumulator whose track-limit result is the stable `car.trackLimitState` object, so connector, pit-analytic, full-sample, and main-track refreshes write wheels, representative state, effective surface, and limit ownership in the classifier pass instead of rescanning the four wheels afterward.
+- Share the projected wheel half-width across the four same-heading main-track wheel patches during the internal analytic apply path and fold analytic wheel writes plus summary into one pass, so the normal local wheel refresh stops recomputing the same projection term four times before summarizing the result again.
+- Replace advanced-physics wheel-surface aggregation and left/right wheel-drag resistance `filter()` / `reduce()` passes with direct scalar loops, removing per-step array churn from the hot advanced integration path while preserving the existing wheel-state contract.
+- Stop broad race-state commits from re-filtering the field for per-car aggression updates, and collapse the common race-order path into one live/DNF partition before sorting.
+- Skip the excluded-participant reset scan on the normal broad-commit path when the ordered list already covers every car, and derive live field depth from the ordered live/DNF boundary instead of another per-commit reduction over the full field.
+- Keep the common running `orderedCars()` path off unnecessary `id -> car` maps and redundant finished/DNF filters, so broad race-state commits only pay those lookup structures in the finished, classified, or frozen-order branches that actually need them.
+- Trim the hot running `orderedCars()` path further by sorting the live field in place and appending DNF cars directly instead of cloning and reassembling extra arrays on the common branch.
+- Reuse the already-built broad-commit ordered field inside finish evaluation instead of recomputing race order again at the end of every normal step, and enforce `0` finish-evaluation ordered-field rescans on the benchmark path.
+- Fold timing-sample recording and timing-line crossing updates into the same per-car broad-commit loop that recomputes race distance and lap telemetry, and enforce one timing-state update per car per commit on the benchmark path.
+- Keep broad-commit DRS references in a reusable per-car indexed scratch array after the physical-track-order pass instead of rebuilding a transient `Map` just to feed the ordered commit loop, and enforce one indexed DRS scratch build per broad commit on the benchmark path.
+- Skip the wrapped-progress physical-order sort inside DRS reference building whenever the active live field still fits inside one lap window, while keeping the old physical-order fallback for lapped-traffic cases where the race order no longer matches the car order on track.
+- Let `calculateWheelSurfaceState()` write the representative state directly into the stable `car.trackState` container on the hot `applyWheelSurfaceState()` path, removing the temporary representative-state object and follow-up copy from local wheel-surface refresh.
+- Keep the advanced simulator physics path on scalar heading axes inside `integrateSimulatorVehiclePhysics()`, removing the per-step temporary `vehicleAxes()` object allocation from the hot velocity projection and acceleration reconstruction path.
+- Make same-lap leader gap seconds accumulate from already-computed interval gaps inside the ordered broad-commit loop, so the normal running path stops re-estimating a separate leader-vs-car timing gap for every follower when finite interval timing is already available.
+- Rework swept collision narrowphase to interpolate body-only rectangles into reusable scratch shapes instead of rebuilding full temporary vehicle geometry for every sweep step.
+- Reuse SAT projection scratch and keep collision narrowphase on direct scalar axis checks instead of rebuilding per-axis projection objects and temporary axis arrays through repeated body-body overlap tests.
+- Keep collision narrowphase contact results, metadata wrappers, and contact-axis containers in reusable scratch storage on hot internal calls, while preserving fresh public no-scratch collision result objects.
+- Keep collision contact velocity response on scalar `velocityX/Y` math instead of rebuilding temporary vector objects for advanced-mode and pit-fixed contact damping, and pin that path in the runtime collision benchmark.
+- Keep collision resolver phase containers in reusable simulation scratch storage, so collidable-car filtering and per-pass reported-contact tracking stay on arrays and typed epoch marks instead of rebuilding arrays or string-key `Set` containers on every collision phase.
+- Keep collision steward context assembly on resolver-owned scratch and scalar velocity math, so fresh-contact reviews stop rebuilding spread metadata/vector helper objects before handing facts to the penalty steward.
+- Emit collision steward penalties directly into the simulation ledger on the internal review path, so fresh-contact review no longer builds an intermediate penalty array before immediately recording the same payloads.
+- Keep collision broadphase candidate de-duplication on scratch-owned typed pair marks, source-indexed distance entries, and reusable missing-distance flag/index arrays instead of object `Map`/`Set` bookkeeping, so hot candidate generation avoids string keys, car-order maps, and fallback sets while preserving the public pair-array result shape.
+- Reuse pit-road and pit-box candidate containers inside indexed pit-lane state resolution, and extend the runtime track-query benchmark so pit-transition queries are explicitly exercised with `pitFallbacks: 0`.
+- Route normal runoff barrier checks through a tiny local segment-neighborhood projection from the previous committed track frame, so main-track cars stop paying both the full nearest-track query and the broader hinted-arc path every step while pit-bound and teleport-like moves still fall back to the broader indexed query path.
+- Reuse the exact local-neighborhood track-state target and returned result wrapper on the common runoff fast path, cutting per-step track-state allocation from post-physics barrier checks without changing runoff query exactness or pit-aware fallback behavior.
+- Tighten the runoff fast path so only roughly meter-scale committed motion uses the smallest exact local-segment neighborhood, while larger non-teleport motion widens back to the broader exact neighborhood automatically and keeps the common benchmark path on the cheaper query radius without weakening exactness.
+- Narrow pit-aware runoff broadphase to connector-only runtime bounds plus a pit-side off-track gate, so true pit-transition edge cases still fall back to the full pit-aware nearest query without collapsing the benchmark path for normal cars running down the pit straight.
+- Replace per-corner runoff barrier reach scans with an analytic body/wheel/visual-footprint reach calculation, keeping barrier contact behavior while removing hot-loop corner projection work.
+- Make hinted local arc projections scan deduped arc-bucket candidates directly instead of first materializing transient candidate arrays, cutting runoff and connector-adjacent query overhead without changing geometric tie-breaking behavior.
+- Make full snapshot JSON serialization use a cached compact track view with rounded static geometry, decimated exported track samples encoded through `track.sampleSchema`, and no engine-only pit bounds / pit-crew metadata or duplicated pit-box/service-area team fields, cutting repeated full-state export cost without changing the live in-memory track object used by the simulator.
+
+### Fixes And Hardening
+
+- Reuse render snapshot buffers, collision candidate arrays, wheel-surface containers, and timing-tower row nodes in hot paths.
+- Synchronize the npm lockfile for clean-checkout installs, including optional transitive `@emnapi` entries that a warm local install can mask during `npm ci --dry-run`.
+
+### Migration Notes
+
+- Update Policy Runner HTTP servers for protocol version `2`: read model inputs from `body.driverIds[index]` plus aligned `body.vectors[index]`, `body.previousActions[index]`, and `body.metrics[index]`, and cache `actionSpec`, `observationSpec`, configuration, `previousActionFields`, and `metricFields` from `/policy/reset`. There is no legacy rich-observation per-decision transport option in Policy Runner server mode.
+- Browser mounts, composable simulator APIs, headless environment imports, and data helper imports keep the `3.0.0` public API shape unless they depend on Policy Runner HTTP server payloads.
+
+### Verification Notes
+
+- The normal package handoff gate is `npm run check`.
+- The final release gate is `npm run check:release`, which adds slow characterization coverage and the full browser smoke matrix.
+- 3.0.0 comparison runs showed real environment stepping faster on the checked worst procedural seeds, including normal-profile seeds `104729`, `4101`, and `47`, and batch-training on the same seeds. A standalone adversarial ray-sensor torture sweep can be slower on kerb/gravel/runoff poses because the current tracer performs more bounded indexed exact validation to preserve driver-precision surface semantics.
+- The final seed sweep covered 69 procedural seeds, 447,120 ray builds, 3,129,840 rays, 149,040 wheel classifications, and 1,380 environment steps with zero invalid ray payloads, wheel classifications, observations, nearest fallbacks, or pit fallbacks.

Rich observation objects, schemas, snapshots, and track metadata are no longer sent on every policy-server decision.
+- Browser mounts, composable simulator APIs, headless environment imports, and data helper imports keep the `3.0.0` public API shape unless they depend on Policy Runner HTTP server payloads.
+
### 3.0.0 Migration Notes
- Remove any `trackQueryIndex` host option. Indexed track queries are always canonical package internals in 3.0.0.
- Rename strict vehicle-physics usage from `physicsMode: 'simulator'` to `physicsMode: 'advanced'`. The old string is no longer accepted and will resolve to the default `physicsMode: 'arcade'`.
- Prefer the semantic `theme` contract for new customization. Partial themes are valid, resolved themes are complete, and one-sided light/dark token overrides generate and cache the opposite mode. Legacy aliases such as `accentColor`, `greenColor`, and `yellowColor` remain migration aliases.
- Use `ui.driverCamera: true` to show the generated Driver camera button, or `initialCameraMode: 'driver'` to start in that mode.
+- Use `@inventure71/paddockjs/environment` for browser-free simulation/training imports.
+- Use `@inventure71/paddockjs/data` for CSS-free data/helper imports such as `DriverData`, `normalizeSimulatorDrivers`, `createProceduralTrack`, and speed conversion helpers.
- `backLinkHref` is sanitized; relative URLs, hash URLs, and absolute `http:` / `https:` URLs are accepted, while unsafe schemes fall back to the package default.
- Full public snapshots include `car.trackState` for the stable car-center track classification shape.
+- Rebuild the host bundle and browser-smoke the host page, including theme toggles, selected-driver surfaces, and any composable mount roots. See [Troubleshooting](docs/troubleshooting.md) if the host build fails after the upgrade.
## Package Release Workflow
The package repo owns its release process:
-- `npm run check` runs fast runtime tests, public type verification, dry-pack verification, packed-consumer install/build verification, the tracked showcase build, and a quick Chromium browser smoke test.

# PaddockJS
-PaddockJS is an installable F1-style simulator component for browser host websites. It owns the simulator source, bundled simulator assets, CSS, demo data, and public mount API.
+PaddockJS is an installable browser component package for an F1-style project race simulator. It owns the simulator UI, PixiJS runtime, bundled simulator assets, CSS, demo data, and public mount APIs. Host websites provide data, page placement, routing, and optional theme choices.
-## Install
+Code snippets in this README are illustrative host integration fragments unless a section says they are a complete runnable file.
-From npm:
+## Install
```bash
npm install @inventure71/paddockjs
```
-## Documentation
-
-Start with [docs/index.md](docs/index.md) for the full package map: what to install, which API to use, what data to pass, how rules modules work, how the browser and headless runtimes differ, and which verification commands prove a change. If you are integrating the package into a host site, read [System Specs](docs/system_specs.md), [Data Contract](docs/data_contract.md), and [Rules](docs/rules.md) first. If you already trained a driver model and want to run it in PaddockJS, use the [Custom Model Controller Guide](docs/custom_model_controller.md).
-
-## Package Workflow
-
-The repo includes the full package-release boundary:
-
-- a tracked showcase host in `local-preview/`
-- public TypeScript declarations in `src/index.d.ts`
-- GitHub Actions CI in `.github/workflows/ci.yml`
-- Changesets release automation in `.github/workflows/release.yml`
-- npm trusted publishing support through GitHub Actions OIDC
-
-Useful commands:
-
-```bash
-npm run check
-npm run check:release
-npm run consumer:smoke
-npm run browser:smoke
-npm run showcase:dev
-npm run showcase:build
-npm run changeset
-```
-
-`npm run check` is the normal local gate: fast runtime tests, public declarations, dry package contents, packed-package consumption in a fresh Vite app, the showcase build, and a quick Chromium smoke against the showcase. `npm run check:release` runs the same package gates plus slow characterization tests and the full browser smoke matrix.
-
-Local development and showcase builds require Node `20.19.0` or newer. CI currently runs the package check on Node 22 and releases on Node 24.
-
-## 3.0 Release Highlights
-
-The `3.0.0` release line adds semantic theme customization with complete resolved light/dark themes, reusable derivative theme packages, component/team theme selectors, cached opposite-mode color generation, and validated color tokens. Indexed track queries are now canonical/internal, so hosts should remove any `trackQueryIndex` option usage. The local preview adds first-class Customization and playable keyboard routes, including theme package switching, selected-team theming, component overrides, pit request/commit/clear, and target-compound controls. The public camera contract includes the opt-in `driver` camera, and full public car snapshots document `car.trackState` as the stable car-center track classification shape.
-
-The release also hardens public URL handling for options such as `backLinkHref`, keeps package readouts safe for partial startup or external-renderer snapshots, preserves scheduler cancellation behavior in `createPaddockDriverControllerLoop()`, and keeps the release workflow centered on `npm run check` plus the final `npm run check:release` gate.
-
-The package still does not ship trained model weights, model storage, a Python Gymnasium/PettingZoo package, static obstacles, weather, reliability failures, fuel-load effects, or debug mutation APIs. Those remain host-owned or future scope.
-
-## Expert Environment API
-
-Headless training code imports the environment subpath:
-
-```js
-import { createPaddockEnvironment } from '@inventure71/paddockjs/environment';
-```
-
-The package root remains the browser component API. The environment subpath is intentionally browser-free and does not import DOM, PixiJS, or package CSS.
-PaddockJS is a bring-your-own-model environment. It does not choose an ML framework, store model weights, or ship a trained driver. The shared `createPaddockDriverControllerLoop()` helper lets a user-owned controller run against either browser expert mode or `createPaddockEnvironment()` with the same batched `decideBatch(context)` call shape.
-
-Browser and headless environments default to `physicsMode: 'arcade'` for existing hosts. Opt into the stricter vehicle model with `physicsMode: 'advanced'` when you want 2D velocity/yaw dynamics, traction limits, steering scrub, derived slip telemetry, reduced off-road grip, and advanced-mode AI tuning:
-
-```js
-const env = createPaddockEnvironment({
- drivers,
- entries,
- controlledDrivers: ['budget'],
- frameSkip: 2,
- physicsMode: 'advanced',
-});
-
-let result = env.reset();
-result = env.step({
- budget: { steering: 0, throttle: 1, brake: 0 },
-});
-```
-
-Action steering is an absolute normalized steering target: `-1` points the wheel to maximum left, `0` points it to center, `1` points it to maximum right, and intermediate values target the same percentage of the maximum angle. Physics still rate-limits how quickly the steering wheel reaches that target.
-
-The environment can run with no reward, as above, or with a host-supplied `reward(context)` callback. Reward formulas stay user-owned; PaddockJS only supplies the neutral facts:
-
-```js
-const env = createPaddockEnvironment({
- drivers,
- entries,
- controlledDrivers: ['budget'],
- reward({ metrics, episode }) {
- if (metrics.destroyed) return -200;
- if (metrics.offTrack) return -12;
- if (episode.terminated) return 0;
- return metrics.legalProgressDeltaMeters;
- },
-});
-```
-
-Reward callback results are converted to numbers per controlled driver. Missing, `NaN`, or infinite callback results become a neutral `0` so one bad callback value cannot poison a training batch.
+Use Node `20.19.0` or newer for local package development and modern Vite-based host builds.
-The repository also includes dependency-free examples that use the same environment contract:
+## Browser Mount
-```bash
-node examples/train-basic-policy.mjs --generations=4 --candidates=5 --episodes=1 --steps=240
-```
-
-The starter script imports the public `@inventure71/paddockjs/environment` subpath and uses self-contained example data from `examples/trainingData.mjs`, so it does not depend on private package source modules for demo drivers. `createProgressReward()` remains available as example/demo reward code only; it is not the official reward and not part of the environment objective.
-
-Each default ray reports track-transition distance and car distance. A track hit uses `kind: 'exit'` when the ray leaves the road and `kind: 'entry'` when an off-track ray points back to the road. Richer sensor layouts are opt-in: rays can use per-ray lengths, predefined layouts such as `driver-front-heavy`, channels for `roadEdge`, `kerb`, `illegalSurface`, and `car`, and `precision: 'driver' | 'debug'`. Driver precision is the default model-facing contract; debug precision is only for clearly labeled diagnostics. Surface channels are computed only when requested. Barrier walls are rendered and enforced as hard destruction boundaries in both physics modes, but they are not model-facing ray targets. `observation.object.self.onTrack` follows the simulator's wheel-level legality rules, so track, kerb, and legal pit-lane/box surfaces are on-track for reward and observation purposes. `pitIntent: 0` is always accepted as the no-op clear value, including environments where pit stops are disabled.
-
-For realistic local-perception policies, use `physicsMode: 'advanced'` with `observation.profile: 'physical-driver'`. It exposes yaw rate, local boundary distances, contact-patch surface readings, richer opponent radar, and surface-aware ray fields in the versioned vector schema. The profile defaults track lookahead to `[]` so the policy does not receive privileged future curvature unless the host explicitly opts back in.
-
-External training code can inspect the environment contract without guessing field ranges:
-
-```js
-const actionSpec = env.getActionSpec();
-const observationSpec = env.getObservationSpec();
-```
-
-Controller modules own model loading, inference, memory, rewards, and logs. PaddockJS supplies cached specs, stable controlled-driver ordering, compact observations, action validation, and repeated stepping through normal physics controls:
-
-```js
-import { createPaddockDriverControllerLoop } from '@inventure71/paddockjs';
-
-const controller = {
- async decideBatch(ctx) {
- return Object.fromEntries(ctx.orderedObservations.map(({ driverId, vector }) => [
- driverId,
- userModelAction(vector),
- ]));
- },
-};
-
-const loop = createPaddockDriverControllerLoop({
- runtime: env,
- controller,
- actionRepeat: 4,
-});
-await loop.reset();
-await loop.step();
-```
-
-`loop.start()` may begin from a fresh runtime and will lazily reset before the first scheduled step. In `onStep(ctx)`, `ctx.actions` is the current applied action map and `ctx.previousActions` is the action map applied on the prior physics step. Scheduled playback stops on controller/runtime errors and exposes the value through `loop.stats.lastError`.
-
-The environment also exposes reset-only scenario placement, neutral rollout recording, deterministic evaluation metrics, and a JSON-serializable worker protocol for external bridges:
-
-```js
-const env = createPaddockEnvironment({
- drivers,
- entries,
- controlledDrivers: ['budget'],
- scenario: {
- preset: 'off-track-recovery',
- placements: {
- budget: { distanceMeters: 420, offsetMeters: 16, speedKph: 65 },
- },
- },
-});
-```
-
-Scenario placement is an environment reset feature, not a policy assist. During `step(actions)`, controlled cars still move only through normalized steering, throttle, brake, and pit intent. `steering`, `throttle`, and `brake` are required for each controlled-driver action; missing or non-finite values fail validation instead of becoming silent zero controls.
-
-For same-environment batched learning, controlled cars can use compact vector observations and reset independently at episode boundaries:
+For a normal website page, mount the all-in-one simulator from the root browser package:
```js
-const env = createPaddockEnvironment({
- drivers,
- entries,
- controlledDrivers: agentIds,
- physicsMode: 'advanced',
- participantInteractions: { defaultProfile: 'batch-training' },
- observation: {
- profile: 'physical-driver',
- output: 'vector',
- includeSchema: false,
- vectorType: 'float32',
- },
- result: {
- stateOutput: 'none',
- resetDriversObservationScope: 'reset',
- },
-});
-
-const schema = env.getObservationSpec();
-let result = env.reset();
-result = env.step(actionsByDriver);
-
-env.resetDrivers({
- [agentIds[0]]: { distanceMeters: 1200, offsetMeters: 3, speedKph: 80 },
-}, {
- stateOutput: 'none',
- observationScope: 'reset',
-});
-```
-
-`batch-training` cars remain real rendered cars in `snapshot.cars`, but they are non-colliding, sensor-hidden, pit-non-blocking, and excluded from race order by default. Step results include `info.drivers[driverId]` episode state and neutral `metrics[driverId]` facts for external logging or user-defined rewards. `stateOutput: 'none'` suppresses repeated `state.snapshot` payloads for high-throughput loops; use `minimal` when the loop still needs the observation snapshot, or omit the option for the full backward-compatible public snapshot. Deterministic evaluation helpers can accept compact no-state base options and internally request the minimal snapshot needed for evaluation metrics. Reset placements are classified against the same runoff/barrier rules before observations are returned: recovery starts stay physical, while cars placed inside terminal barrier space return destroyed metrics and stable miss-valued rays instead of running far-out ray geometry.
-
-On the package's local 20-car simulator benchmark with front-heavy physical-driver rays, compact vector/no-state output measured around `3.3ms` per environment action, with a no-ray baseline around `1.5ms`. Those numbers are hardware dependent, but they show the intended usage: keep schema/spec lookup separate, request compact vectors in training loops, and reserve full snapshots for debugging or visualization.
-
-For multi-car training and visual comparison, PaddockJS separates real participants from replay overlays:
-
-- `participantInteractions` changes how physics-driven cars interact with collisions, sensors, pit occupancy, and race order. Those cars remain in `snapshot.cars` and still move through steering, throttle, brake, pit intent, tire state, timing, and rules.
-- `replayGhosts` are trajectory-driven overlays for reference laps, debugging, or comparison. They appear in `snapshot.replayGhosts`, never in `snapshot.cars`, and do not collide, rank, pit, or trigger penalties. They are sensor-hidden by default and only appear in rays or nearby observations when their own sensor flags opt in.
-- In the browser view, non-colliding participants remain solid clickable cars but get a blue no-collision outline marker. Replay ghosts remain translucent overlays.
+import { mountF1Simulator } from '@inventure71/paddockjs';
-```js
-const env = createPaddockEnvironment({
- drivers,
- entries,
- controlledDrivers: ['model-a', 'model-b'],
- participantInteractions: {
- drivers: {
- 'model-a': { profile: 'isolated-training' },
- 'model-b': { profile: 'isolated-training' },
+const root = document.getElementById('sim-root');
+
+if (root) {
+ await mountF1Simulator(root, {
+ drivers: [
+ {
+ id: 'budget',
+ name: 'Budget Buddy',
+ color: '#ff2d55',

+ timingName: 'Budget',
+ },
+ ],
+ onDriverOpen(driver) {
+ if (driver.link) window.location.href = driver.link;
},
- },
-});
+ });
+}
```
-`isolated-training` is the no-collision profile for real cars that should still remain in race order. `batch-training` is the preferred no-collision profile for same-environment learner batches because it is also excluded from race order. Both profiles hide the car from other cars' ray sensors and `nearbyCars` observations by default; use `phantom-race` or explicit `detectableByRays` / `detectableAsNearby` overrides only when sensor visibility is intentional.
-
-Browser expert mode is opt-in through the normal mount API. When enabled, the visual simulator advances only when host code calls `simulator.expert.step(actions)`. Expert mode is a mount-time boundary; changing `expert` through `restart(nextOptions)` is rejected so ticker ownership cannot silently change under a mounted simulator.
-Browser expert mode uses the same episode lifecycle as the headless environment. The default episode horizon is a high safety cap (`1_000_000` expert steps, roughly 4.6 hours at 60Hz with `frameSkip: 1`) so normal user-facing sessions should end by race finish, not by the safety cap. Training and evaluation loops should set a smaller explicit `expert.episode.maxSteps` or `episode.maxSteps` when they need bounded rollouts; `episode.endOnRaceFinish` keeps normal race completion as the terminal condition.
-Set `expert.visualizeSensors` to draw expert sensor rays inside the actual race canvas for visual debugging:
+The root package is browser-oriented and imports package CSS. If your host build does not extract CSS from JavaScript imports, import the stylesheet explicitly:
```js
-const simulator = await mountF1Simulator(root, {
- drivers,
- entries,
- expert: {
- enabled: true,
- controlledDrivers: ['budget'],
- frameSkip: 4,
- visualizeSensors: {
- rays: true,
- },
- },
-});
+import '@inventure71/paddockjs/styles.css';
```
-The overlay renders ray values from the same active observation returned by `simulator.expert.step(actions)`; it does not recompute a separate sensor model for the browser layer. Each detected ray channel is shown as its own colored marker, so road-edge, kerb, illegal surface, and car hits can be inspected independently. This applies to every model-facing sense: Policy Runner and expert visualizations must show what the policy receives, while extra high-precision diagnostics must be labeled separately.
-
-When multiple drivers are controlled, sensor visualization renders the selected controlled driver by default so batch-training previews do not draw every agent's rays every frame. Use `visualizeSensors: { rays: true, drivers: 'all' }` only when you intentionally want the heavier all-controlled-car overlay.
+PaddockJS CSS is scoped under package mount/component roots and uses system font stacks. The package does not load Google Fonts or any other remote font. Hosts that want branded typography should load fonts in the host app.
-## API
+Start here:
-The root package exports the browser mounts, composable helper mounts, data/rating helpers, bundled asset and preset constants, procedural-track helper, simulator unit converters, and `createPaddockDriverControllerLoop`. The browser-free training runtime lives under `@inventure71/paddockjs/environment`; see [docs/system_specs.md](docs/system_specs.md) for the full export catalog.
+- [Getting Started](docs/getting-started.md): install, browser mount, CSS, assets, host responsibilities, and container sizing.
+- [Data Contract](docs/data_contract.md): driver, entry, callback, rules, and option shapes.
+- [Troubleshooting](docs/troubleshooting.md): common integration failures and supported checks.
-All-in-one mount:
+## Composable Layouts
-```js
-import { mountF1Simulator } from '@inventure71/paddockjs';
-
-const simulator = await mountF1Simulator(document.getElementById('sim-root'), {
- preset: 'timing-overlay',
- drivers: [
- {
- id: 'budget',
- name: 'Budget Buddy',
- color: '#ff2d55',
- link: '/project_details/project-budget-buddy.html',
- raceData: ['AI finance coach', 'Python + LLM', 'Budget guardrails'],
- },
- ],
- entries: [
- {
- driverId: 'budget',
- driverNumber: 71,
- timingName: 'Budget',
- driver: { pace: 52, racecraft: 74, aggression: 38, riskTolerance: 47, patience: 81, consistency: 86 },
- vehicle: { id: 'budget-bb01', name: 'BB-01 Ledger', power: 48, braking: 72, aero: 55, dragEfficiency: 66, mechanicalGrip: 63, weightControl: 58, tireCare: 82 },
- },
- ],
- initialCameraMode: 'show-all',
- expert: {
- enabled: true,
- controlledDrivers: ['budget'],
- },
- onDriverOpen(driver) {
- window.location.href = driver.link;
- },
-});
-```
-
-Composable mount:
+Use `createPaddockSimulator()` when a host wants to place package-owned surfaces in separate roots while keeping one simulator controller:
```js
import { createPaddockSimulator } from '@inventure71/paddockjs';
-const simulator = createPaddockSimulator({
- drivers,
- entries,
- onDriverOpen(driver) {
- window.location.href = driver.link;
- },
-});
+const simulator = createPaddockSimulator({ drivers, entries });
simulator.mountRaceControls(document.getElementById('sim-controls'));
-simulator.mountCameraControls(document.getElementById('sim-camera-controls'));
-simulator.mountSafetyCarControl(document.getElementById('sim-safety-car'));
-simulator.mountTimingTower(document.getElementById('sim-timing'));
simulator.mountRaceCanvas(document.getElementById('sim-race'), {
+ includeTimingTower: true,
includeRaceDataPanel: true,
});
-simulator.mountTelemetryCore(document.getElementById('sim-telemetry-core'));
-simulator.mountTelemetrySectors(document.getElementById('sim-telemetry-sectors'));
-simulator.mountTelemetrySectorBanner(document.getElementById('sim-telemetry-sector-banner'));
-simulator.mountTelemetryLapTimes(document.getElementById('sim-telemetry-laps'));
-simulator.mountTelemetrySectorTimes(document.getElementById('sim-telemetry-sector-times'));
-simulator.mountCarDriverOverview(document.getElementById('sim-overview'));
+simulator.mountRaceDataPanel(document.getElementById('sim-race-data'));
await simulator.start();
```
-The race canvas can also own the timing tower when a host wants a single reusable race-window component:
+The controller methods are the canonical composable API. See [Composable Layouts](docs/composable-layouts.md) for the available surfaces, lifecycle, restart behavior, and sizing contract.
-```js
-simulator.mountRaceCanvas(document.getElementById('sim-race'), {
- includeTimingTower: true,
- includeRaceDataPanel: true,
- timingTowerVerticalFit: 'scroll',
-});
-```
+## Headless And Data Subpaths
-For a packaged race-window template with a right-side telemetry drawer:
+Do not import the root package from raw Node or headless training code. The root package is for browser mounts and imports CSS/assets.
-```js
-simulator.mountRaceTelemetryDrawer(document.getElementById('sim-race-workbench'), {
- timingTowerVerticalFit: 'expand-race-view',
- raceDataTelemetryDetail: true,
-});
-```
-
-When a composable host intends to use pit APIs or automatic pit behavior, include the pit rules in the simulator options before mounting components:
+Use the browser-free environment subpath for simulation/training loops:
```js
-const simulator = createPaddockSimulator({
- drivers,
- entries,
- rules: {
- ruleset: 'custom',
- modules: {
- pitStops: { enabled: true },
- stalledDnf: { enabled: true },
- tireStrategy: { enabled: true, mandatoryDistinctDryCompounds: 2 },
- },
- },
-});
+import { createPaddockEnvironment } from '@inventure71/paddockjs/environment';
```
-`drivers` is the host-owned project/pilot list. `entries` is the optional driver/car/team pairing sheet. The car/driver overview uses the existing driver and vehicle rating components from each entry. Driver and vehicle entries can also include `customFields` as extra label/value metadata. Entries can include `team: { id, name, color, icon, theme, pitCrew }`; the timing tower uses the team icon, defaults team color to the car color when omitted, and can map `team.theme` into the semantic theme system. `team.pitCrew` accepts `speed`, `consistency`, and `reliability` values from `0` to `1` for optional pit-service variability. Assets, including the default car image and generic driver helmet, are bundled by default, so the host website does not need to provide simulator images or textures.
-
-The returned object supports:
-
-- `destroy()`
-- `restart(nextOptions)` for non-asset, non-expert race/data/seed changes
-- `selectDriver(driverId)`
-- `setSafetyCarDeployed(deployed)`
-- `setRedFlagDeployed(deployed)`
-- `setPitLaneOpen(open)`
-- `callSafetyCar()`
-- `clearSafetyCar()`
-- `toggleSafetyCar()`
-- `setPitIntent(driverId, intent, targetCompound?)`
-- `getPitIntent(driverId)`
-- `getPitTargetCompound(driverId)`
-- `getSimulationSpeed()`
-- `setTimingGapMode(mode)`
-- `getTimingGapMode()`
-- `toggleTimingGapMode()`
-- `servePenalty(penaltyId)`
-- `cancelPenalty(penaltyId)`
-- `getSnapshot()`
-- `expert` when explicitly enabled, otherwise `null`
-
-Timing gap mode is controller-owned, not tied to whether the manual tower toggle is visible. `setTimingGapMode('interval')` makes timing rows show interval to the car ahead, `setTimingGapMode('leader')` makes them show gap to P1, and `toggleTimingGapMode()` switches between those two values. These methods can be called after mounting or while the race is running; mounted timing towers update immediately and keep the same selected driver/order state.
-
-Useful UI options:
+Use the CSS-free data subpath for tooling, server-side data normalization, and procedural track helpers:
```js
-preset: 'timing-overlay',
-theme: {
- mode: 'system',
- use: 'trackside',
- tokens: {
- primary: { light: '#008c55', dark: '#00ff84' },
- pitLane: '#7c3aed',
- },
- themes: {
- trackside: {
- extends: 'default',
- tokens: { yellowFlag: { dark: '#ffcc00' } },
- components: {
- button: { background: 'pitLane', text: 'primaryText', border: 'primary' },
- },
- },
- },
- componentThemes: {
- 'race-controls': 'trackside',
- },
- timingTowerMaxWidth: '360px',
- raceViewMinHeight: '720px',
-},
-ui: {
- layoutPreset: 'left-tower-overlay',
- cameraControls: 'external',
- showFps: false,
- telemetryIncludesOverview: false,
- telemetryModules: ['core', 'sectors', 'lapTimes', 'sectorTimes'],
- raceDataBanners: {
- initial: 'project',
- enabled: ['project', 'radio'],
- },
- raceDataBannerSize: 'auto',
- raceDataTelemetryDetail: true,
- timingTowerVerticalFit: 'expand-race-view',
- timingGapMode: 'interval',
- timingGapModeToggle: true,
- timingEntryVerticalPadding: 5,
-},
-debug: {
- physicsModeIndicator: false,
-}
+import { DriverData, normalizeSimulatorDrivers } from '@inventure71/paddockjs/data';
```
-`preset` is resolved before explicit host options. Available presets are `dashboard`, `timing-overlay`, `compact-race`, and `full-dashboard`; hosts can start from a preset and override any `ui`, `debug`, or `theme` field. `debug.physicsModeIndicator: true` renders a small top-left race-canvas square: blue for arcade physics and red for advanced physics. It defaults to `false` for package consumers and is intended only for debug/development use. `theme` resolves semantic package tokens into complete light/dark themes, can define reusable named theme packages with `extends`, and can assign a named theme to component scopes such as `race-controls` through `componentThemes`. Component theme keys accept package `data-paddock-component` names and camelCase aliases such as `raceControls` or `timingTower`; `selectedDriverPanel` targets both selected-driver package surfaces. Selected-driver surfaces such as the car/driver overview and race-data panel use the selected team's theme by default when one is available. Unknown theme tokens or component slots are ignored, one-sided light/dark token overrides generate and cache the opposite mode, and theme plus driver/team colors are validated before they are written to CSS variables. Legacy aliases such as `accentColor`, `greenColor`, and `yellowColor` still map to the semantic token system for migration.

-### Layout Support Contract
-
-PaddockJS supports the all-in-one shell and host mount roots in containers at least `320px` wide. Hosts should size the outer mount root with normal responsive CSS, for example `width: 100%; min-width: 0;`, and avoid adding host rules that target package internals such as `.sim-grid`, `.sim-timing`, or `.race-data-panel`. The host owns page placement; PaddockJS owns the shell, timing-board width, camera safe area, lower-thirds, drawer behavior, focus styles, and touch target sizing. Package-owned subcomponents can have smaller internal widths when their own layout is designed for it; for example, the broadcast timing tower remains valid at its package-owned narrow width. Responsive narrow template variants are enabled by default and can be disabled with `ui.responsiveNarrowLayout: false` or the matching composable mount option when a host intentionally wants the older stacked timing/drawer behavior.
-
-The package uses container-width density tiers:
-
-- `320px` to `519px`: mobile density. Controls wrap, embedded timing towers stop reserving a side gutter and use the package timing reveal, telemetry drawers reveal over the race view, and lower-thirds compress inside the race view. The lower-third may cover empty timing-tower chrome, but if it would cover any timing entries the race view adds package-owned banner clearance to its minimum height. If the entries remain clear, no extra banner height is reserved.
-- `520px` to `759px`: narrow tablet density. Race surfaces keep readable controls while standalone telemetry and overview modules collapse to single-column layouts.
-- `760px` to `1119px`: tablet density. Side-by-side host sections may still give an individual component a narrow container, so package components use their own container width rather than viewport width.
-- `1120px` and wider: desktop density. The broadcast timing tower can sit in the left race gutter at its package-owned width, and telemetry/drawer layouts use wider horizontal space.
-
-If the shell/mount root receives less than `320px` inline size, or an individual package component is constrained below its component-specific minimum, PaddockJS marks it with `data-paddock-size-unsupported="true"` and shows an accessible `Unsupported size` placeholder. That is intentional: below the support envelope, the package prefers a clear placeholder over clipped controls, horizontal scrolling, or overlapping race UI. The placeholder is package-owned and uses `role="status"` with polite live-region behavior.
-
-Package controls, drawer toggles, lower-third actions, and close buttons maintain practical `44px` touch targets. Timing rows are compact selectable broadcast entries with configurable vertical padding. Touch driving controls are not part of the package; the playable preview remains keyboard/expert-action driven and does not add a virtual joystick.
+Read [Headless Environment](docs/headless-environment.md), [Data Helpers](docs/data-helpers.md), and [Bring Your Own Model](docs/training.md) for those paths.
-If `trackSeed` is omitted, each mounted browser simulator creates a fresh procedural circuit. Passing `trackSeed` makes the track deterministic so multiple embeds can share the same generated circuit; repeated procedural seeds are cached within the page runtime as immutable track definitions. Treat values returned by `createProceduralTrack()` as read-only and pass custom mutable copies when experimenting with track-definition edits. `restart({ trackSeed })` rebuilds the race on the deterministic circuit for the new seed. Asset URL changes are not restartable; destroy and mount a new simulator when changing assets.
+## Runtime Theming
-Warmup is enabled by default across browser, headless environment, and direct simulation creation. The runtime warms a disposable instance during loading and caches by configuration fingerprint, so identical resets/restarts skip repeated warmup while seed/config changes warm again automatically. Override with `warmup: { enabled, policy: 'config-change' | 'always' | 'never', steps }` or `warmup: false`.
-
-Generated circuits are built from seeded connected region boundaries that are smoothed and warped into a validated centerline, so tracks can include concave infield/outfield sections and chicane-like bends instead of simple oval-like fallback shapes. Hosts can pass `trackGeneration` alongside `trackSeed` to choose a profile and override semantic generation controls:
+Use mount-time `theme` for defaults and controller methods for runtime site theme toggles:
```js
-const simulator = await mountF1Simulator(root, {
- drivers,
- entries,
- trackSeed: 4101,
- trackGeneration: {
- profile: 'training-short',
- length: { minMeters: 900, maxMeters: 1800 },
- startStraight: { gridMeters: 0 },
- pitLane: { enabled: false },
- },
- rules: {
- modules: {
- pitStops: { enabled: false },
- },
- },
-});
-
-simulator.restart({
- trackSeed: 5051,
- trackGeneration: { profile: 'race' },
-});
-```
+const simulator = await mountF1Simulator(root, { drivers, entries });
-Advanced callers can import `createProceduralTrack(seed, options)` when they need the generated track definition directly instead of mounting a simulator:
+simulator.setThemeMode(document.documentElement.dataset.theme === 'light' ? 'light' : 'dark');
-```js
-import { createProceduralTrack } from '@inventure71/paddockjs';
-
-const trainingTrack = createProceduralTrack(4101, {
- profile: 'training-short',
- length: { minMeters: 900, maxMeters: 1800 },
- startStraight: { gridMeters: 0, exitMeters: 80, blendMeters: 80 },
- pitLane: { enabled: false },
- shape: { scale: 0.2, cornerDensity: 1.3, variation: 0.22 },
- validation: { minClearanceMultiplier: 1, maxLocalTurnRadians: 1.85 },
- attempts: { primary: 80, fallback: 200 },
+const stopThemeSync = simulator.syncThemeFrom(document.documentElement, {
+ attribute: 'data-theme',
+ map: { light: 'light', dark: 'dark' },
});
```
-Profiles are presets, not separate generators. `race` preserves the default full circuit with pit lane; `training-short`, `training-medium`, and `training-technical` generate smaller pitless circuits for training or demos. Resolution is `race` defaults, then the selected profile, then explicit overrides.
-
-Pit-lane geometry depends on the resolved generation options. The `race` profile includes:
-
-- rendered pit lane beside the start/finish straight
-- lane-aligned procedural entry and exit roads
-- main fast lane sized from the team/box layout
-- parallel working lane
-- 10 shared team service areas
-- 20 unused garage boxes arranged as 10 team pairs
-
-Training profiles disable pit-lane generation by default. If a host explicitly sets `pitLane: { enabled: false }`, pit-related rules should also be disabled or left in a no-op configuration.
+Do not restart the simulator only to change presentation. Runtime theme APIs keep race state, selected driver, penalties, speed, camera state, and pit intent state. See [Theming](docs/theming.md).
-Pit-lane asphalt, working-lane service areas, and garage boxes are legal drivable surfaces for sensors, runoff handling, track-limit stewarding, and stalled-DNF timing. In both physics modes, the rendered barrier wall marks the hard outer runoff boundary; cars whose footprint reaches the wall's inner face are marked `destroyed`, stopped, removed from active collision/sensor participation, and treated as DNF entries at the bottom of the timing order. `physicsMode` changes vehicle integration and grip behavior, not barrier consequences. Environment results expose destruction as neutral `metrics[driverId].destroyed` and a per-driver `endReason: 'destroyed'`, so training loops can assign their own negative reward and then call `resetDrivers()` for a new episode. Opt-in stalled off-track DNF uses `endReason: 'stalled-off-track'` without setting `destroyed`. Tire energy degrades down to 1% and affects grip nonlinearly, so badly worn tires are slower and harder to rotate without making the car instantly undrivable.
+## Upgrade From 2.x
-When `rules.modules.pitStops.enabled` is true, cars automatically form bounded pit trains when lane space is available. They brake to the limiter by the main pit-lane start, drive along the main fast lane, pass through the team queue spot as a rolling gate, roll into the team-colored working-lane service area when it is clear, stop, serve eligible penalties before tire work, show the remaining stationary service time above the car, change to the requested configured tire compound or the default alternate compound, and exit back to the race track.
+If a host is moving from 2.x-era usage, use [Upgrading Hosts To PaddockJS 4.x](docs/upgrading-hosts-to-3.md). The short version:
-`tireStrategy` does not enable automatic pit stops. It controls available compounds, pit-stop target compound choices, and tire-requirement stewarding. Use `rules.modules.pitStops.enabled: true` for automatic pit routing and pit APIs, or choose a preset such as `ruleset: 'fia2025'` / `ruleset: 'grandPrix2025'` that enables both pit stops and the two-compound tire strategy by default.
+- install `@inventure71/paddockjs@4`
+- remove `trackQueryIndex`
+- replace `physicsMode: 'simulator'` with `physicsMode: 'advanced'` or omit it for `arcade`
+- import package CSS intentionally for browser mounts
+- use `/environment` for headless simulation and `/data` for CSS-free helpers
+- rebuild and browser-smoke the host page
-Team-mates share one service area. Every car enters through the queue spot first, but it only stops there when the active service spot is blocked. A second team car waits in the queue spot until the active service spot is physically clear, including the previous car's first movement out of the box, without blocking the main fast lane.
+## Reference Docs
-By default, built-in AI cars request an opportunistic `pitIntent: 1` below 50% tire energy and commit `pitIntent: 2` below 30%. Hosts can change those thresholds with `tirePitRequestThresholdPercent` and `tirePitCommitThresholdPercent`. Expert/headless controlled drivers do not receive those automatic tire-threshold calls and must request service with `pitIntent`.
+Normal consumers should start with the task docs above. These reference docs are the deeper package source of truth:
-Hosts can override the pit call with `setPitIntent(driverId, 0 | 1 | 2, 'H')` or expert action `{ pitIntent: 2, pitCompound: 'H' }`:
+- [System Specs](docs/system_specs.md): public API, runtime guarantees, and verification standards.
+- [Rules](docs/rules.md): race-control behavior, DRS, safety car, starts, ordering, contact handling, pits, penalties, and simulation rules.
+- [Concepts](docs/concepts.md): simulator vocabulary.
+- [Architecture](docs/architecture.md): module ownership and data/control flow for package contributors.
+- [Component Inventory](docs/component_inventory.md): package-owned UI surfaces and template ownership.
-- `0` means no request
-- `1` means keep trying until a free pit-entry window is available
-- `2` means commit to entering at the next pit-entry window even when pit-lane capacity or gap checks would block an opportunistic stop
-
-Completed stops can be re-armed later by tire condition or by `setPitIntent`, so pit stops are not one-use per race. Optional `pitStops.variability` uses `team.pitCrew` speed, consistency, and reliability to adjust service time and slow-stop chance; `pitStops.variability.perfect: true` forces deterministic default service time for training.
-
-`setPitLaneOpen(false)` keeps new pending pit calls on track until reopened and the canvas shows a small red/green/yellow light near pit entry. `setRedFlagDeployed(true)` freezes race movement, closes the effective pit lane, and emits red-flag race-control state until cleared. The pit speed limiter applies on the straight main pit lane/working lane, not on the entry and exit connector roads, but automatic pit-entry routing still keeps connector speeds bounded so cars can reach the limiter safely.
+## Package Workflow
-Race behavior is configurable through `rules`. Flat existing options such as `standingStart: false` remain supported, and advanced behavior is grouped under module config:
+Useful local commands:

+npm run showcase:dev
```
-For deterministic single-skill training or visual checkpoint comparison, set `rules.modules.tireDegradation.enabled: false` so tyre energy remains fixed while the car still drives through normal steering, throttle, brake, and surface physics. `rules.modules.stalledDnf` defaults to `enabled: false` so base simulator and training environments keep stuck off-track cars live unless a host opts in. Set `enabled: true` to retire cars that are off legal racing or pit surfaces while below `speedThresholdKph` for `maxStoppedSeconds`.
-
-Supported rulesets are `paddock`, `grandPrix2025`, `fia2025`, and `custom`. Presets only choose defaults; explicit module config wins. Weather, reliability, and fuel-load performance effects are reserved future modules and are not active `3.0.0` behavior. Penalty subsections use `strictness` from `0` to `1` instead of plain booleans. Track limits use the white line as the legal edge and require all four wheel contact patches to be fully outside the same side of the line before recording a violation, so normal kerb riding is not punished. Per-car `surface` is resolved from the worst wheel surface, snapshots include `car.wheels` for per-wheel surface and white-line state, and asymmetric left/right wheel resistance adds a small capped yaw tug toward the slower side when only one side is on a worse surface. Collision stewarding is driven by a body collision hull, not transparent sprite bounds or wheel-only overlap, and contact events include shape ids, contact type, depth, and time of impact. It considers impact severity, closing speed, and whether one car clearly hit another from behind; clear rear contact penalizes only the physically trailing car, including lapped traffic cases, while unclear meaningful contact records shared-fault penalties for both cars. Stalled off-track DNFs emit `car-dnf` with `reason: 'stalled-off-track'`, freeze the car, remove it from active control/collision/sensor/pit participation, and classify it with the existing DNF metadata. Pit-lane speeding is enforced on the main fast lane, working lane, service areas, and garage boxes, but not on pit-entry or pit-exit connector roads. Track-limit warnings are emitted as `track-limits` events, while penalty decisions are exposed through `snapshot.penalties` plus `penalty` events. Penalty consequences support warning, time, drive-through, stop-go, position-drop, grid-drop, and disqualification payloads. Time consequences are additive, drive-through and stop-go penalties are service obligations, and unserved service penalties convert to configured time at final classification.
-
-`initialCameraMode` accepts `'overview'`, `'leader'`, `'selected'`, `'driver'`, `'show-all'`, or `'pit'`; invalid values fall back to `'leader'`. The overview camera frames the active generated track bounds, including package-owned track padding and pit-lane extent, instead of using a fixed world-center zoom. Camera mode changes ease from the current camera target to the next target after the initial frame, so switching between leader, selected, driver, overview, show-all, and pit views does not snap the world view.
-
-The pit camera targets the generated operational pit-lane geometry, including the lane, boxes, service areas, and queue areas, while excluding the longer entry/exit access roads. It zooms out as needed to fit that work area inside the active race-view safe area, and its control is hidden when the active track has no pit lane.
-
-The driver camera follows the selected car from a lower screen anchor and rotates the world so the car's heading points upward. Its control is opt-in through `ui.driverCamera: true`, and setting `initialCameraMode: 'driver'` enables that control automatically.
-
-Zoom buttons and wheel zoom apply to every camera mode. Zoom-out is bounded by the active generated track frame so the camera cannot pull far beyond the circuit. The renderer keeps grass coverage larger than the simulated world, and the transparent canvas host uses the same grass color as a fallback around the framed circuit.
-
-`layoutPreset: 'left-tower-overlay'` creates a left broadcast gutter inside the race view, frames the camera around the remaining race area, and places the timing tower in that gutter without covering camera controls. The project/radio lower-third stays inside the race window and can intentionally render over the timing sidebar instead of shrinking around it.
-
-Composable hosts should pass `{ includeRaceDataPanel: true }` to `mountRaceCanvas()` when they want that lower-third clipped and layered by the race window. `mountRaceDataPanel()` remains available for hosts that intentionally want the banner as a standalone surface.
-
-`raceDataTelemetryDetail: true` makes the project lower-third include a compact S1/S2/S3 sector strip with live sector elapsed time and per-sector progress. That telemetry project lower-third stays visible until dismissed, muted, or replaced, while radio mode keeps its normal schedule. The standalone `mountTelemetrySectorBanner()` surface remains available only when a host explicitly mounts it.
-
-`includeTimingTower: true` embeds the timing tower directly inside the race canvas and reserves camera space from the measured tower gutter when the tower is a side overlay. In narrow hosts, the embedded timing tower becomes a package-owned left reveal panel opened by the race view's Timing control instead of taking permanent height above the track. The control updates `aria-expanded`, the closed tower is inert/hidden to assistive tech, and the renderer/camera keep resizing through the transition without remounting the simulator. This responsive narrow behavior is enabled by default; pass `responsiveNarrowLayout: false` to `mountRaceCanvas()` or set `ui.responsiveNarrowLayout: false` to opt out.
-
-`mountRaceTelemetryDrawer()` is a higher-level template that mounts an external top control row, race canvas, embedded timing tower, lower-third, top steward message, safety-car control, and a telemetry drawer together. Pass `{ raceDataTelemetryDetail: true }` when the drawer lower-third should include compact sector detail. On narrow hosts the responsive template is enabled by default: the top workbench controls stack into full-width rows, the safety-car and telemetry actions become a two-column row, the telemetry drawer reveals over the race view instead of forcing the race canvas to reserve permanent drawer height, and the race view measures lower-third/timing-entry geometry before adding extra vertical clearance. Pass `{ responsiveNarrowLayout: false }` to opt out.
-
-The drawer top row contains camera controls, a `1x` simulation-speed button that cycles through `2x`, `3x`, `4x`, `5x`, `10x`, and back to `1x`, a `Mute banners` toggle, safety car, and the telemetry toggle so those controls do not cover the race. For other camera-control placements the speed button is hidden by default and can be enabled with `ui.simulationSpeedControl: true`.
-
-`Mute banners` is off by default and temporarily suppresses project/radio lower-thirds while it is pressed; steward penalty banners are separate and remain controlled by `penaltyBanners`. Opening the drawer reduces the race area instead of overlaying it, and closing it removes the drawer from interaction. The drawer uses the same package-owned `telemetry-stack` component as `mountTelemetryPanel()`, so constrained host heights scroll telemetry vertically instead of letting the sidebar escape its frame.
-
-Banner and timing layout options:
-
-- `raceDataBanners.initial` selects the starting banner state: `'project'`, `'radio'`, or `'hidden'`.
-- `raceDataBanners.enabled` chooses which banner types may appear.
-- `raceDataBannerSize: 'auto'` uses the race space to the right of the timing board when it is wide enough and falls back to the full lower-third overlap when it is not.
-- `raceDataBannerSize: 'custom'` preserves the default CSS-variable-driven lower-third size for hosts that want to tune their own banner geometry.
-- `timingTowerVerticalFit: 'expand-race-view'` lets the race window grow tall enough for the tower.
-- `timingTowerVerticalFit: 'scroll'` keeps the race window height and scrolls the timing list inside the cropped tower.
-- `timingGapMode: 'interval'` starts the timing tower in `Int` mode, showing interval to the car ahead. Use `'leader'` to start in `Gap` mode, showing the total gap to P1.
-- `timingGapModeToggle: true` shows the compact timing-tower header toggle by default. Set it to `false` when the host should own mode changes through `setTimingGapMode()`, `getTimingGapMode()`, or `toggleTimingGapMode()`.
-- `timingEntryVerticalPadding: 5` adds `5px` above and below each timing entry. Set one non-negative number to change all entry rows together.
-
-The same timing fit values can be passed to `mountRaceCanvas()` when `includeTimingTower` is enabled. Standalone timing towers are capped by `--timing-board-max-width` and fill their mount root height; placing the root in a fixed-height container makes only the timing entries scroll. Timing entries always stack from the top as compact content-sized rows, so P1/P2 occupy the same vertical positions whether the race has 2 cars or 20. Use `timingEntryVerticalPadding` when the tower needs looser or denser row spacing.
-
-The timing tower defaults to `Int` mode and includes a single compact `Int`/`Gap` header toggle unless `ui.timingGapModeToggle: false` is set. The toggle lives in the timing header's gap column and is package-owned: it keeps the same header alignment as `POS`, `TEAM`, `PROJECT`, and `TYRE`, uses a practical `44px` hit target, and draws selected/focus states inside the tower header so the broadcast proportions do not shift. Hosts should not replace this with custom CSS against package internals. If a host needs a different control placement, hide the header toggle and call the controller methods from host-owned UI instead.
-
-Hosts can set the initial mode with `ui.timingGapMode` and can change it at any time with `setTimingGapMode('interval' | 'leader')`, `getTimingGapMode()`, or `toggleTimingGapMode()`. `Int` shows the interval to the car ahead, while `Gap` shows total gap to the leader. Seconds gaps are measured from hidden fixed timing-line crossings on the track. If a car is one or more whole laps behind in the selected mode, the tower shows labels such as `+1` or `+2` instead of a seconds estimate.
-
-Other UI switches:
-
-- `cameraControls` defaults to `'external'`; set it to `'embedded'` only when controls should intentionally appear inside the canvas, or `false` to omit them.
-- `penaltyBanners: true` shows warnings and penalties in the top steward message instead of the project/radio lower-third.
-- `showFps: false` hides the FPS readout.
-- `telemetryIncludesOverview: false` keeps the car/driver overview out of the telemetry stack so hosts can mount `mountCarDriverOverview()` separately.
-- `telemetryModules` controls optional package-owned telemetry surfaces: `core`, `sectors`, `lapTimes`, and `sectorTimes`.
-
-Project/radio lower-thirds include a package-owned top-right close button that hides the current pill before its scheduled timeout. Time penalties put a large `+10s` style chip in the left block of the steward message and the affected car/rule beside it. Warning messages use warning colors and do not create timing-row `!` badges. The telemetry surfaces are also available as fully detached mount methods.
-
-### Composable overlay layout contract
-
-`ui.layoutPreset: 'left-tower-overlay'` is package-owned. Hosts should not recreate or depend on internal shell classes such as `.sim-shell--left-tower-overlay` or `.sim-grid` as their public integration contract.
-
-For the all-in-one simulator, call `mountF1Simulator()` and let PaddockJS generate the shell. For composable layouts, hosts should provide mount roots and call package mount methods such as `mountRaceCanvas(root, { includeTimingTower: true, includeRaceDataPanel: true })` or `mountRaceTelemetryDrawer(root)`. Host CSS may size the outer container, but timing-tower placement, gutter measurement, camera safe area, and narrow-screen stacking are owned by PaddockJS.
-
-Mounted package surfaces include a lightweight red start-light loading overlay. The runtime removes each overlay after PixiJS, assets, controls, and the initial readouts are ready.
-
-The runtime also pauses its render ticker when the race canvas is offscreen or the browser tab is hidden. This keeps pages with multiple PaddockJS embeds responsive without requiring host code to manually start and stop each simulator. At `5x` and `10x` browser playback, noncritical timing/readout DOM refreshes run at a lower cadence while fixed-step simulation and race events keep using authoritative race state.
-
-Lifecycle callbacks are optional and host-owned. PaddockJS emits `onLoadingChange`, `onReady`, `onError`, `onDriverSelect`, `onRaceEvent`, `onLapChange`, and `onRaceFinish`; lifecycle callback errors are routed to `onError` when provided and do not stop the simulator loop. `onDriverOpen(driver)` is host-owned navigation code and is not wrapped as a lifecycle callback. Race snapshots include per-car interval timing, leader-gap timing, whole-lap gap counts, calibrated `speedKph`, automatic `track.sectors`, hidden `track.timingLines`, per-car `lapTelemetry`, finish state, `raceControl.winner` after the first finisher, and final `raceControl.classification` only after the whole field is finished or DNF. Sector telemetry clears future-sector values so banners and sidebars show completed splits before the active sector plus the active live timer, not stale later-sector entries. Cars that have crossed the line before full race completion expose `raceStatus: 'waved-flag'` / `wavedFlag: true` and stay frozen in provisional finish order; later barrier contact or stalled-off-track detection does not turn that result into DNF. Destroyed/out-of-race cars expose DNF metadata, show `DNF` at the bottom of the timing tower, render faded/gray in the race canvas, and appear after finishers in final classification with no finish time. If a DNF car is restored before final classification, it re-enters live timing and the race waits for it again; once `raceControl.finished` is true, classification stays final. Final classification applies time penalties and unserved service conversions through `adjustedFinishTime`, then applies position-drop and disqualification consequences to finishers before DNF entries. The field then circulates in safety-car mode and the race canvas shows a package-owned winner banner.
+`npm run check` is the normal local gate: docs checks, fast runtime tests, public declarations, dry package contents, packed-package consumption in a fresh Vite app, the showcase build, and a quick Chromium smoke against the showcase. `npm run check:release` adds slow characterization tests and the full browser smoke matrix.

Observation output formatting is separate from object/vector construction so compact training loops can request vector-only results while `getObservationSpec()` remains the schema source. Vector-only mode uses a direct vector path and can return `Float32Array` buffers without building the full public object observation. When a loop requests vector-only, schema-free, no-state output, `runtime.js` uses the internal `snapshotTraining()` path instead of the heavier public observation snapshot; returned state still uses public snapshot shapes. Environment-owned simulations always use the internal track query index because repeated track/surface/ray queries otherwise dominate step cost. `sensors.js` is a compatibility barrel; nearby-car scans, ray defaults, ray config normalization, track rays, surface rays, indexed ray-band intersections, car rays, body senses, contact-patch senses, boundary senses, opponent radar, and ray geometry live under `src/environment/sensors/`. Expensive surface-ray channels are opt-in and appear in the vector schema whenever requested. Replay-ghost sensor type flags are also part of compact ray/nearby-car vectors so vector-only consumers can distinguish real cars from opt-in references. Driver rays use a precision-aware cached origin state and shared per-observation ray target context. Driver `precision: 'driver'` road-edge, kerb, and illegal-surface channels use the canonical indexed projection path with driver-precision validation. Destroyed/out-of-race cars keep the active ray schema but short-circuit to miss-valued rays before creating track ray contexts, which prevents terminal cars in batch training from repeatedly querying far-out geometry. Pit-connector and unusual cases can still use sampled validation internally. Ray precision defaults to the model-facing `driver` contract; `debug` precision is diagnostic-only and must not be silently substituted into policy inputs or model-sense visualization.
-- `metrics.js` owns reward-neutral per-driver facts such as progress delta, legal progress delta, off-track/severe-cut state, destroyed state, low-speed state, spin/backwards/instability state, lap completion, lap time, and contact count. Contact metrics dedupe the identifiers on each normalized physical contact event so one event increments each involved driver once. It must not encode or choose rewards.

Vector-only mode uses a direct vector path and can return `Float32Array` buffers without building the full public object observation; schema-free ray values are appended into the final vector instead of first allocating per-ray value arrays. When a loop requests vector-only, schema-free, no-state output, `runtime.js` uses the internal `snapshotTraining()` path instead of the heavier public observation snapshot; returned state still uses public snapshot shapes. `runtime.js` also owns reusable observation scratch for environment results, and `observations.js` uses it to keep controlled-driver car lookup maps and event-grouping containers stable across headless reset/step builds while no-scratch direct calls retain fresh lookup containers. Environment-owned simulations always use the internal track query index because repeated track/surface/ray queries otherwise dominate step cost. `sensors.js` is a compatibility barrel; nearby-car scans, ray defaults, ray config normalization, track rays, surface rays, indexed ray-band intersections, car rays, body senses, contact-patch senses, boundary senses, opponent radar, and ray geometry live under `src/environment/sensors/`. Expensive surface-ray channels are opt-in and appear in the vector schema whenever requested. Replay-ghost sensor type flags are also part of compact ray/nearby-car vectors so vector-only consumers can distinguish real cars from opt-in references. Driver rays use a precision-aware cached origin state, shared per-observation ray target context, and optional per-batch scratch storage for ray-detectable target arrays and target wrappers, rich ray result containers, shared indexed-query objects, filtered car targets, reusable ray-boundary offset/distance/segment-id containers, reusable tracer result containers, validated boundary samples, and bounded sampled-recovery samples. Scratch reuse is internal to environment/render loops; exported sensor calls without scratch continue returning fresh arrays/objects. Driver `precision: 'driver'` road-edge, kerb, and illegal-surface channels use direct indexed ray-band intersections for safe main-track geometry, including track edge, kerb outer edge, gravel edge, and runoff edge. Normal driver candidates are validated against driver-precision track state before they become model-facing values; validated off-track recovery boundaries can also remain on the direct path. The ray-band tracer owns boundary-distance scratch and the returned road-edge/kerb/illegal-surface result shell through the per-ray shared query so direct model-facing rays reuse their offset list, distance list, segment-id list, boundary result object, and channel result objects instead of rebuilding those containers per ray. Pit-lane-origin side rays whose current pit-road frame proves the lateral road boundary resolve directly from pit-road normal/width geometry with no nearest-track sampling; ambiguous recovery, pit-connector, and unproven pit-lane-origin rays stay inside the ray-band tracer as a single bounded sampled-recovery pass for all requested road/surface channels. Debug precision also uses that tracer-owned route with additional sampled refinement for diagnostic distances; only missing-index cases use the older sampled fallback path. The `batch-training` interaction profile now uses that same tracer-owned road/surface path for safe main-track rays, including kerb/illegal-surface-only batches that synthesize same-pose origin state from `progress`/`signedOffset` and pass a main-track-only tracer mode so pit-connector-adjacent training rays stay on direct indexed geometry instead of sampled connector recovery. Destroyed/out-of-race cars keep the active ray schema but short-circuit to miss-valued rays before creating track ray contexts, which prevents terminal cars in batch training from repeatedly querying far-out geometry. Ray precision defaults to the model-facing `driver` contract; `debug` precision is diagnostic-only and must not be silently substituted into policy inputs or model-sense visualization.
+- `rayChannels.js` owns the canonical ray channel list, reusable scalar channel-flag containers, and legal-surface predicate used by the ray-band tracer. Scratch-backed driver rays write requested-channel dispatch into the per-ray shared query instead of allocating channel `Set` instances, and runtime benchmarks require zero channel-set allocations plus stable channel-flag containers on the common direct ray path. Scratch-backed ray batches also cache normalized raw ray option objects and keep ray-option normalization on scalar loops, so rich/vector/append sensor passes reuse the same normalized rays and channel arrays. Scratch-backed car-ray target discovery also keeps the all-target wrapper array and each self-filtered per-car target array stable, using scalar writes rather than callback-driven list rebuilding before the exact footprint checks.
+- `metrics.js` owns reward-neutral per-driver facts such as progress delta, legal progress delta, off-track/severe-cut state, destroyed state, low-speed state, spin/backwards/instability state, lap completion, lap time, and contact count. Contact metrics dedupe the identifiers on each normalized physical contact event so one event increments each involved driver once. `runtime.js` owns reusable metric scratch for environment result builds, and `metrics.js` uses it to keep previous/current car lookup maps plus contact-count grouping containers stable across headless reset/step builds while no-event builds skip contact-count containers. It must not encode or choose rewards.
- `recorder.js` owns neutral rollout transition export. It snapshots observations, actions, rewards, next observations, terminal flags, and info at record time and does not interpret rewards or policies.
- `controllerLoop.js` owns browser/headless controller orchestration around an injected runtime. It may lazily reset a fresh runtime before scheduled playback, but public `reset()` remains an explicit playback stop. Controller contexts report current `actions` separately from `previousActions`, where previous means the last action map actually applied before the current physics step. It maintains an observation cache so reset-only `resetDrivers()` results can stay small without handing null observations to the next batch decision for non-reset controlled drivers. Scheduled playback catches controller/runtime failures, stops the loop, and exposes the thrown value through loop stats.
+- `local-preview/src/policyRunner/controllers.js` owns the browser Policy Runner HTTP policy-server transport. Its protocol is intentionally compact: reset sends static specs/configuration plus `previousActionFields` and `metricFields` once, while per-decision JSON contains only `driverIds` plus aligned numeric `vectors`, compact previous-action tuples, compact metric tuples, and events. It must not reintroduce full observation objects, schemas, snapshots, or static track metadata into `/policy/decide-batch`; those belong in reset/init metadata or explicit debug/export surfaces.

The broad commit is the only normal active-step phase that recalculates race distance, laps, sector timing, timing-line crossings, order, gaps, DRS latch state, finish state, and classification-facing rank fields. Same-lap leader gaps now accumulate from already-computed interval gaps inside that ordered broad-commit loop instead of re-estimating a fresh leader-vs-car timing gap for every same-lap follower, with the direct leader estimate kept only as a fallback when interval timing is not finite. Interval gap estimation itself now bounds timing-line lookups to the overlapping stored line window for the two cars instead of scanning the whole retained line-history span every time, returns before touching timing-line crossings at all when either car has not stored a valid timing-line window yet, and skips the timing-line helper call entirely on that empty-window path so the common broad-commit wrapper falls straight back to timing-history interpolation without extra timing-line setup work. Sector-performance classification is also dirty-gated inside the commit: the simulation still keeps `lapTelemetry.sectorPerformance` exact, but it only rebuilds the field-wide current/last/best sector classification buffers when a sector split or reset changed the underlying sector arrays or when the field-wide overall best sector values changed.

Broad race-state commits should derive nearest-ahead DRS references from one physical-track-order pass over the current active field instead of re-scanning the whole field per car. When the active running field still fits inside one lap window, the DRS helper may safely reuse the already ordered race field as that physical order and skip the extra wrapped-progress sort altogether; once lapped traffic appears, it falls back to the explicit physical-order sort so DRS can still reference physically ahead backmarkers correctly.

Local refresh updates current wheel/track state needed by post-motion rule phases without changing timing/order. When runoff has already computed a center track state for the same final pose, local refresh may reuse it; if collision correction changed the pose, it discards that pending state and queries from the final position. Connector-adjacent wheel refresh now keeps those reused center states on an exact local segment-neighborhood path for wheel-center classification, instead of falling back to broad nearest-track scans at each wheel. Normal active steps now treat that local refresh as the authoritative post-motion surface pass, so the following broad commit reuses the already-committed wheel/track state instead of recomputing the same surface classification a second time for every car. The broad commit also derives DRS references from a one-pass physical track ordering once per commit instead of calling back into per-car whole-field DRS scans, keeps those references in a reusable per-car indexed scratch array rather than rebuilding a transient `Map` just to feed the ordered commit loop, and now skips that extra physical-order sort entirely when the ordered live field is provably still inside one lap window. DRS latch updates also cache the currently active zone reference on the car, cache the next detection-zone index across steady forward motion, mutate zone detection records in place, and stay on a sim-bound scalar call path during broad commits so the hot loop avoids rebuilding the same options object for every car on every step. External car-state changes clear that next-zone cache so repositioned cars still detect later zones correctly. It passes one precomputed live field depth into aggression updates instead of re-filtering the full field once per car, skips the excluded-participant reset scan entirely when the ordered list already covers every car in the field, and threads that same ordered field into finish evaluation instead of recomputing race order again at the end of the commit. On the common non-finish path, that finish evaluation now stays on one direct ordered-field pass instead of allocating a temporary `newlyFinished` array and then rescanning the field again just to prove the race is still running.

On that current-pose cache, wheel and body corners now stay lazy by default and are only materialized when a sampled wheel-surface path actually needs them; once materialized they are updated in place and reused across pose changes. The hot current-only cache also drops the old string signature bookkeeping, because runtime consumers match pose through the cached pose object itself rather than through rebuilt `x:y:heading` strings. Root `src/simulation/vehicleGeometry.js`, `vehiclePhysics.js`, and `wheelSurface.js` are compatibility re-exports.
+
+`src/simulation/collisionGeometry.js` owns shape-confirmed vehicle contact. It first prunes pairs by nearby track progress with a circular-track window, then uses swept body AABBs, SAT body/body overlap checks, and conservative continuous checks between previous and current poses. Hot internal broadphase calls reuse scratch-owned candidate arrays, pooled pair arrays, source-indexed distance entries, typed pair marks for candidate de-duplication, and reusable missing-distance flag/index arrays; public no-scratch candidate queries still return fresh pair arrays. Candidate generation carries each sorted distance entry's source car index directly into hidden pair metadata and the pair marker, so the hot path no longer builds an object `Map` for car order or a fallback `Set` for missing-distance membership. The swept narrowphase now interpolates body-only shapes into reusable scratch rectangles instead of rebuilding full temporary vehicle geometry on every sweep sample. Hot internal collision calls also keep shape-contact results, vehicle-contact metadata, and their contact-axis objects in reusable scratch containers; public no-scratch collision queries still return fresh result objects. The simulation collision resolver uses the hidden candidate-pair indexes to mark already-reported fresh contacts in a scratch-owned typed epoch buffer instead of building string keys in a `Set` during the collision phase. Wheel shapes are intentionally excluded from car-vs-car collision for cost and stability; wheel geometry is still used by the surface and track-limit pipeline. `raceSimulation.js` only orchestrates response/cooldown/steward review after this module returns contact metadata, and collision stewarding derives rear-contact fault from physical track order so lapped cars are handled consistently.
+
+`src/simulation/track/spatialQueries.js`, `pitLaneState.js`, and the pit sections of `trackQueryPitIndex.js` own drivable-region state resolution. Main-track nearest projection stays indexed through the centerline query index, while pit-road and pit-box candidate lookup stays inside the pit query index. The pit query helpers can now reuse scratch candidate arrays/route buckets for hot internal callers such as `nearestTrackState()`, so pit entry/fast-lane/working-lane/exit and pit-box classification no longer rebuild temporary candidate containers on every call. Indexed pit-road classification also projects restricted entry/fast-lane/working-lane/exit candidate segments into one reusable polyline result while reading cumulative route distances precomputed on the pit query index, instead of rebuilding candidate sets, filtered segment arrays, and distance arrays per route. Connector-adjacent direct pit-entry/pit-exit override checks use that same query-index-owned polyline projection target and route metadata. Endpoint-progress shortcuts read precomputed route endpoint segment windows, while mid-connector points without an endpoint progress hint read bounded route candidates from the pit index without becoming full pit-lane queries, so connector shortcuts avoid full-route pit-entry/pit-exit projection scans and transient projection objects. Direct sensor-ray boundary tracing also asks the query index for reusable segment IDs and then reads typed centerline arrays directly, leaving temporary segment-object materialization to the public/debug `queryTrackSegmentsAlongRay()` helper instead of the hot ray-band tracer. `pitLaneState.js` also skips pit-box grid lookups entirely when a point is outside the dedicated box/service-area bounds, which removes wasted garage/service misses from connector-adjacent wheel and track classification. Transition resolution still chooses between indexed main-track and indexed pit-lane states, but the benchmark gate now explicitly exercises pit queries and requires direct connector projection scratch reuse, positive endpoint-window connector projection calls, zero direct connector full-route projection scans, pit-road grid hits, reused pit-road projection scratch, precomputed pit-road route distances, zero cumulative-distance rebuilds, zero road-grid misses, and `pitFallbacks: 0`. `trackStatePolicy.js` also owns the car-specific runoff fast path: when the previous committed track frame is valid and pit geometry is irrelevant, it resolves the new main-track frame through an exact local segment-neighborhood projection instead of the broader nearest-track search or hinted-arc path, using the tightest exact radius only for roughly meter-scale committed motion and widening back to the broader exact neighborhood automatically when motion is larger. That single-car runoff path now writes its exact local-neighborhood result into a reusable per-car track-state target and reuses a stable result wrapper, so the common post-physics runoff query avoids per-step track-state allocation without changing the exact geometric contract. Pit-aware runoff now only exits that fast path when the previous committed state is already beyond the main-road edge on the pit-lane side and the new pose lands inside connector-only runtime bounds, so normal on-track cars near the pit straight keep the exact local query path while true pit-transition edge cases still fall back to the full pit-aware nearest resolution.

+`src/simulation/vehicle/wheelSurface.js` owns per-wheel track sampling and the effective car surface. Surface priority, analytic main-track classification, and pit-lane/connector classification are split into `surfacePriority.js`, `mainTrackWheelSurface.js`, and `pitWheelSurface.js`. On normal main-track running it uses the cached wheel geometry and the car center's track normal to analytically classify each wheel patch from signed offsets. That normal-running apply path now shares the projected wheel half-width across the four same-orientation patches and folds analytic wheel writes plus surface/track-limit summarization into one pass, so the hot local-refresh path stops recomputing the same projection term and rewalking the same four wheels just to summarize them. The dominant common case now short-circuits directly to that analytic branch whenever the resolved center state is on the main track and not near a pit connector, instead of first walking the pit/connector decision tree before landing on the same result. Near pit connectors it still resolves ambiguous wheel centers through exact local segment-neighborhood projections anchored on the already-known center track segment, but those wheel-center projections now use a tighter exact radius for the real connector cases, write into reusable projection containers, and can be queried as one shared batch instead of rebuilding the same neighborhood search separately for each wheel. Straight connector-adjacent main-track poses first prove the full wheel footprint against the center track frame and skip those wheel-center projections entirely when every patch remains inside the main-track limits, so centered pit-straight connector refreshes use the same analytic writes as normal main-track running. When an exact batch is needed and proves every wheel center still belongs to the main track, the post-query apply path now stays on a one-pass analytic summary instead of routing each wheel back through the slower mixed connector branch plus a second summary pass. Connector-adjacent main-track cars whose full wheel footprint stays on the opposite half of the track from the pit-lane side skip those connector track queries entirely and stay on the plain analytic main-track path, because pit overlap is geometrically impossible in that region. Indexed pit geometry or full patch samples still run only when that local geometric pass says the wheel is genuinely ambiguous against pit-road bounds. Center-in-pit-lane states still use pit analytics when the whole patch fits inside the road and fall back to full sampling otherwise. The internal `applyWheelSurfaceState()` path keeps per-car scratch storage for wheel arrays, wheel objects, sampled-state arrays, reusable connector wheel-center states, reusable connector wheel-center projections, reusable connector wheel-center point refs, a reusable wheel-summary accumulator, a stable mutable `car.trackState`, and a stable cache wrapper so the post-physics refresh path avoids replacing hot-loop containers when only the field values changed; it now also passes the reusable queried-state target array straight through the exact connector batch query instead of allocating a fresh state array and copying the results back out. On cache misses it threads the already-resolved current geometry straight through `calculateWheelSurfaceState()` instead of rereading the same current-geometry cache a second time. Its cache-hit validation now compares geometry pose and explicit center-state fields directly instead of rebuilding per-call cache signature strings, so repeated explicit-center refreshes stay on the cheap cache-hit path without avoidable string churn. It also reads current-pose vehicle geometry from a current-only cache so pre-physics wheel-surface checks do not rebuild wheel geometry just because swept-collision history (`previousX/Y/Heading`) was refreshed, and that current-only geometry cache now updates its body/wheel containers in place when the current pose changes while leaving wheel/body corners lazy until a sampled path requests them, so post-physics local refresh stops rebuilding unused current-geometry corner trees every step without weakening exact sampled wheel checks. The final wheel summary now stays in the classifier pass for scratch-backed main-track, connector, pit-analytic, and full-sample branches, and its reusable `trackLimits` object is the car's stable `trackLimitState`; runtime benchmarks require the summary container, track-limit object, wheel containers, sampled-state objects, and representative track-state object to stay reused. Direct calculation calls still return fresh public containers, but they now use the same scalar wheel writer batches and direct full-patch sampler functions instead of rebuilding callback-driven patch-sample arrays; the wheel-surface benchmark requires scratchless scalar writer batches and one scalar wheel write per wheel on the direct connector path. `vehiclePhysics.js` consumes that effective surface through the car track state, and separately compares left-side and right-side wheel resistance to add a small capped yaw bias toward the slower side.
-`src/simulation/vehicle/wheelSurface.js` owns per-wheel track sampling and the effective car surface. Surface priority, analytic main-track classification, and pit-lane/connector classification are split into `surfacePriority.js`, `mainTrackWheelSurface.js`, and `pitWheelSurface.js`.

It falls back to full patch sampling near pit connectors and inside pit-lane states. `vehiclePhysics.js` consumes that effective surface through the car track state, and separately compares left-side and right-side wheel resistance to add a small capped yaw bias toward the slower side.
+Timing maintenance is also kept allocation-light now. Runtime timing writes in `timingHistory.js` use a fixed structured ring store for per-car `{ time, raceDistance }` samples, so broad commits no longer allocate a fresh object for every timing sample and long-running races stay bounded without repeated array churn. Structured timing-history interpolation also caches the last successful neighborhood and probes that bracket first on the next nearby lookup, which matches the normal adjacent-car broad-commit pattern and avoids repeatedly rescanning the same trailing timing-history window from the tail. `interpolateTimeAtDistance()` still accepts the older array-of-objects shape so characterization tests and legacy internal fixtures can keep using explicit sample arrays where needed. `timingLines.js` likewise caches the first and last retained mini-sector line numbers, so pruning old timing-line crossings only walks the numeric range when the pruning cutoff actually advances instead of rescanning object keys every step, and zero-travel updates with an unchanged cutoff now stop at the timestamp refresh instead of rewalking stored line keys.

Browser frame paths may fill reusable render-source and interpolation buffers, while public snapshot methods continue returning fresh caller-owned snapshot objects.
The app runtime pauses its PixiJS ticker when the race canvas is outside the viewport or the document is hidden, then resets the frame clock before resuming. Runtime visibility uses `IntersectionObserver` plus a bounded canvas-geometry check on observer, scroll, resize, focus, and page-show events so a visible canvas cannot remain paused because of a stale observer result. Ticker synchronization also compares the intended runtime state with PixiJS' actual `ticker.started` state before deciding whether to call `start()` or `stop()`. This prevents host pages with several simulator embeds from running every race while only one is visible, and avoids a large simulation catch-up step when the canvas re-enters view. Camera safe-area layout measurements are cached and invalidated by resize observation so the 60 FPS render path does not force repeated DOM geometry reads. Camera framing derives a cached active-track bounds box from generated samples plus pit-lane extent; overview uses that frame directly, and every camera uses it as the zoom-out floor. The first camera frame is applied immediately, then later camera mode changes interpolate target position and scale so leader/selected/overview/show-all/pit switches do not jump the world view. Runtime readouts avoid redundant DOM writes for unchanged text, timing markup, finish classification, and static selected-car overview data, and `updateDom()` reuses its supplied full snapshot for camera-control availability instead of taking another public snapshot. Static pit-lane status graphics are redrawn only when their status/geometry key changes, and DRS trail histories are pruned in place. Startup marks the initial DOM refresh time so the first ticker frame does not immediately redo the same full readout update. At `5x` and `10x` browser playback, noncritical DOM/timing refreshes are throttled more aggressively while fixed-step simulation, event emission, and rendering continue from authoritative simulation state. Long project-radio delays are also treated as stale schedule state instead of replaying every missed lower-third transition.

+# Composable Layouts
+
+Use composable layouts when a host page wants to place package-owned simulator pieces in separate DOM roots. The host owns placement and surrounding page layout; PaddockJS still owns generated markup, CSS variables, race state, timing state, and component behavior.
+
+## Create One Controller
+
+```js
+import { createPaddockSimulator } from '@inventure71/paddockjs';
+
+const simulator = createPaddockSimulator({
+ drivers,
+ entries,
+ onDriverOpen(driver) {
+ if (driver.link) window.location.href = driver.link;
+ },
+});
+```
+
+Keep one controller per race runtime. Mount the surfaces you need, then start it:
+
+```js
+simulator.mountRaceControls(document.getElementById('sim-controls'));
+simulator.mountCameraControls(document.getElementById('sim-camera-controls'));
+simulator.mountSafetyCarControl(document.getElementById('sim-safety-car'));
+simulator.mountRaceCanvas(document.getElementById('sim-race'), {
+ includeTimingTower: true,
+ includeRaceDataPanel: true,
+ timingTowerVerticalFit: 'scroll',
+});
+simulator.mountRaceDataPanel(document.getElementById('sim-race-data'));
+
+await simulator.start();
+```
+
+Controller methods are the canonical composable style. The standalone mount helper exports exist for compatibility, but new host code should prefer `simulator.mountRaceCanvas(root)` and the matching controller methods.
+
+## Available Surfaces
+
+- `mountRaceControls(root)`
+- `mountCameraControls(root)`
+- `mountSafetyCarControl(root)`
+- `mountTimingTower(root)`
+- `mountRaceCanvas(root, options)`
+- `mountTelemetryPanel(root)`
+- `mountTelemetryCore(root)`
+- `mountTelemetrySectors(root)`
+- `mountTelemetrySectorBanner(root)`
+- `mountTelemetryLapTimes(root)`
+- `mountTelemetrySectorTimes(root)`
+- `mountRaceTelemetryDrawer(root, options)`
+- `mountCarDriverOverview(root)`
+- `mountRaceDataPanel(root)`
+
+`mountRaceCanvas()` can embed the timing tower and race-data lower-third when the host wants a single package-owned race window. `mountRaceTelemetryDrawer()` mounts a larger workbench with top controls, race canvas, timing tower, safety-car control, and telemetry drawer.
+
+## Lifecycle
+
+```js
+await simulator.start();
+
+simulator.selectDriver('budget');
+simulator.setTimingGapMode('leader');
+simulator.setPitLaneOpen(false);
+
+simulator.restart({ trackSeed: 5051 });
+simulator.destroy();
+```
+
+Use `restart(nextOptions)` for race/data/seed changes. Use `setTheme()`, `setThemeMode()`, or `syncThemeFrom()` for presentation changes so the race does not reset.
+
+Browser expert mode changes are not a casual restart setting. Expert mode changes ticker ownership and freezes the visual simulator until host code steps it, so only enable it intentionally for policy playback or debugging.
+
+## Sizing
+
+Each mounted root receives PaddockJS component scope classes and package CSS variables. Hosts may size the outer roots, but timing-board width, broadcast proportions, camera safe area, drawer behavior, lower-thirds, focus styles, and touch targets remain package-owned.
+
+Use `includeTimingTower: true` when the race canvas should own the timing tower placement. Use `timingTowerVerticalFit: 'scroll'` to keep a fixed race height with a scrolling timing list, or `'expand-race-view'` when the race window may grow to fit the tower.

+# Getting Started
+
+Use this guide when installing PaddockJS into a normal browser host website.
+
+## Install
+
+```bash
+npm install @inventure71/paddockjs
+```
+
+PaddockJS is a browser component package. A host page gives it a root element, project/driver data, and optional routing callbacks. PaddockJS owns the simulator shell, PixiJS renderer, CSS, default assets, race controls, timing tower, telemetry surfaces, and simulation runtime.
+
+## Mount The Simulator
+
+```html
+
+```
+
+```js
+import { mountF1Simulator } from '@inventure71/paddockjs';
+
+const root = document.getElementById('f1-simulator-root');
+
+if (root) {
+ await mountF1Simulator(root, {
+ drivers,
+ entries,
+ title: 'F1 Simulator Lab',
+ kicker: 'Race Control',
+ backLinkHref: '/projects',
+ backLinkLabel: 'Projects',
+ onDriverOpen(driver) {
+ if (driver.link) window.location.href = driver.link;
+ },
+ });
+}
+```
+
+Use the root package only for browser mounts and browser helper exports. It imports package CSS and bundled simulator assets.
+
+## CSS
+
+Most browser bundlers consume the root package stylesheet automatically. If your host build does not, import the stylesheet explicitly from a browser entry:
+
+```js
+import '@inventure71/paddockjs/styles.css';
+```
+
+Package CSS is scoped to PaddockJS mount roots/components. It uses system font stacks and does not load Google Fonts or any remote font. Hosts that want branded typography should load fonts in the host app.
+
+Do not target package internals such as `.sim-grid`, `.timing-list`, `.race-data-panel`, `.camera-controls`, or `.start-lights` from host CSS. Size the mount root; let PaddockJS own internal layout.
+
+## Assets
+
+Hosts should not copy simulator assets into their own source tree. PaddockJS ships its default car, safety-car, logo, panel, and track texture assets. Browser bundlers such as Vite, Rollup, and Webpack bundle those assets from the package.
+
+## Container Sizing
+
+PaddockJS supports mount roots at least `320px` wide. Use normal responsive host CSS:
+
+```css
+.simulator-section {
+ width: 100%;
+ min-width: 0;
+}
+```
+
+If a package surface is constrained below its supported size, PaddockJS shows an `Unsupported size` placeholder rather than clipping controls or overlapping race UI.
+
+## Where To Go Next
+
+- Use [Composable Layouts](composable-layouts.md) when the host needs separate package-owned surfaces.
+- Use [Theming](theming.md) for runtime light/dark sync and token customization.
+- Use [Data Contract](data_contract.md) for full driver, entry, rule, UI, callback, and asset option shapes.
+- Use [Troubleshooting](troubleshooting.md) when a host build or browser smoke fails.

+# Headless Environment
+
+Use the environment subpath for browser-free simulation, JavaScript training loops, evaluation, and worker bridges.
+
+```js
+import { createPaddockEnvironment } from '@inventure71/paddockjs/environment';
+```
+
+Do not import the root package from raw Node or headless tooling. The root package is a browser component entry and imports CSS and image assets.
+
+## Basic Loop
+
+```js
+const env = createPaddockEnvironment({
+ drivers,
+ entries,
+ controlledDrivers: ['budget'],
+ frameSkip: 4,
+ physicsMode: 'advanced',
+});
+
+let result = env.reset();
+result = env.step({
+ budget: { steering: 0, throttle: 1, brake: 0 },
+});
+
+env.destroy();
+```
+
+`controlledDrivers` is required. Controlled actions use normalized `steering`, `throttle`, and `brake`, plus optional `pitIntent` and `pitCompound`.
+
+## Training Boundary
+
+PaddockJS owns deterministic stepping, observations, action validation, specs, neutral metrics, scenario reset placement, browser playback hooks, and optional reward callback plumbing. The user owns the ML framework, model weights, reward formula, storage, checkpoints, logs, and training algorithm.
+
+For realistic local-perception policies, prefer:
+
+```js
+const env = createPaddockEnvironment({
+ drivers,
+ entries,
+ controlledDrivers: ['budget'],
+ physicsMode: 'advanced',
+ observation: { profile: 'physical-driver' },
+});
+```
+
+Use `env.getActionSpec()` and `env.getObservationSpec()` instead of guessing action ranges or vector fields.
+
+## Browser Expert Mode
+
+Browser expert mode is opt-in through the browser mount API and is for visual policy playback/debugging:
+
+```js
+const simulator = await mountF1Simulator(root, {
+ drivers,
+ entries,
+ expert: {
+ enabled: true,
+ controlledDrivers: ['budget'],
+ frameSkip: 4,
+ },
+});
+```
+
+When expert mode is enabled, the visual simulator advances only when host code calls `simulator.expert.step(actions)`. Do not enable expert mode in basic consumer examples; it is easy to think the simulator is broken because it is intentionally waiting for model actions.
+
+For the full contract, see [Bring Your Own Model](training.md), [Custom Model Controller Guide](custom_model_controller.md), and [Model Sense Contract](sense_contract.md).

-Ray observations expose track-transition distance and car distance per ray.

Track-position, surface, pit-lane, and ray fallback queries use an internal non-enumerable track query index built with the track model. Browser/expert mounts, headless environments, direct race-simulation construction, and compact training-style environment runs all use the indexed path. This changes runtime cost, not public observation shapes.
+Ray observations expose track-transition distance and car distance per ray. Track transitions use `kind: 'exit'` when the ray starts on track and reaches the border, `kind: 'entry'` when the ray starts off track and reaches the road again, and `kind: null` with max distance when no transition is visible. Driver-precision road-edge, kerb, and illegal-surface channels use direct indexed ray-band intersections when the candidate boundary can be validated against driver track state, including validated off-track recovery boundaries. Barrier-origin recovery rays also stay on the direct indexed path when the tracer can already prove road-edge/kerb misses and the first non-barrier illegal-surface entry. Direct ray-band intersection consumes query-index segment IDs and typed centerline arrays instead of materializing temporary segment objects; the object-returning segment query helper remains for public/debug callers. Scratch-backed internal ray batches reuse the rich ray channel containers for road-edge, kerb, illegal-surface, and car hits, and car-hit footprint checks reuse the caller-owned ray vector plus a per-ray result target instead of recomputing ray geometry; no-scratch public ray calls still return fresh channel objects. Batch-training surface-only ray batches synthesize safe main-road origin state from same-pose `progress`/`signedOffset` geometry and reuse shared track-band boundary plus surface-hit containers, so kerb/illegal-surface channels stay indexed without nearest-track origin classification or per-ray hit-object replacement. Ambiguous recovery, pit-connector, and pit-lane-origin rays that are still not provable from the indexed bands are resolved by one bounded sampled recovery pass inside the ray-band tracer so all requested road/surface channels share the same sampled states. Debug precision uses the same tracer-owned path with additional sampled refinement for diagnostic distances; only missing-index cases use the older sampled fallback path. Track-position, surface, pit-lane, and ray fallback queries use an internal non-enumerable track query index built with the track model. Pit-road state classification reuses indexed route candidate buckets, one polyline projection result, and precomputed cumulative route distance tables for entry, fast-lane, working-lane, and exit roads. Connector-adjacent direct pit-entry/pit-exit override checks reuse that same projection target and route metadata; endpoint-progress shortcuts use precomputed endpoint segment windows, and mid-connector points use bounded indexed route candidates without becoming full pit-lane queries. The runtime track-query benchmark explicitly requires those pit-road probes to stay indexed with reused direct connector scratch, positive endpoint-window connector projections, zero connector full-route projection scans, reused route scratch, precomputed distances, zero cumulative-distance rebuilds, and zero pit fallbacks. Browser/expert mounts, headless environments, direct race-simulation construction, and compact training-style environment runs all use the indexed path. This changes runtime cost, not public observation shapes.

+Scratch-backed internal ray batches also keep requested-channel dispatch in reusable scalar channel flags owned by the shared ray query. The runtime benchmark contract fails if the common direct sensor-ray path allocates channel `Set` containers or replaces those channel-flag containers between batches.
The package must not own model training, model persistence, model registries, or trained policy behavior. The supported contract is: external code reads observations, returns normalized actions, and advances either the headless environment or browser expert mode.
The shared expert runtime exposes `getActionSpec()` and `getObservationSpec()` so external code can inspect controlled drivers, action ranges, sensor layout, nearby-car limits, track lookahead fields, and the versioned vector schema before connecting a model. Environment reset may apply deterministic scenario placement presets or explicit placement/traffic layouts; model steps may not mutate position and still use normalized actions only. Neutral rollout recording, deterministic evaluation metrics, and the JSON worker protocol are environment utilities, not training algorithms.
`createPaddockDriverControllerLoop({ runtime, controller, actionRepeat })` is the shared public controller orchestrator for browser playback and JavaScript training-style loops. `runtime` may be browser expert mode or a headless environment, and `controller.decideBatch(context)` is called once per policy step for all controlled drivers in stable spec order. The loop lazily resets when scheduled playback starts from a fresh instance, caches `actionSpec` and `observationSpec`, reuses the active observation payload, supports async controllers, forwards actions through the normal `step(actions)` API, and repeats each decision for `actionRepeat` runtime frames. Scheduled playback stops and records `stats.lastError` when controller initialization, decision, stepping, or `onStep` hooks fail. `stop()` cancels pending package-owned scheduler handles and custom scheduler handles that either expose `cancel()` or return browser-style numeric timeout/animation-frame ids. It does not load checkpoints, run neural networks, parse model formats, compute rewards, or mutate vehicle state.

- `theme` is the public sizing/color contract. It resolves semantic package-owned tokens into complete light/dark themes, supports named derivative theme packages through `theme.themes`, selects the active package with `theme.use`, applies component-specific packages through `theme.componentThemes`, and accepts team selectors through `theme.teamThemes` or `entries[*].team.theme`. Component theme keys accept package component ids such as `timing-tower` and camelCase aliases such as `timingTower`; `selectedDriverPanel` targets both selected-driver package surfaces. Selected-driver surfaces use the selected team's theme by default when one is available while structural controls keep the active global theme unless explicitly overridden. Unknown theme tokens or component slots are ignored, one-sided light/dark token overrides generate and cache the opposite mode, and theme plus driver/team colors are validated before they are written to CSS variables. Legacy aliases such as `accentColor`, `greenColor`, and `yellowColor` remain migration aliases for the new semantic tokens.
+- `setTheme(theme)`, `setThemeMode(mode)`, and `syncThemeFrom(element, options)` are runtime presentation APIs. They must resolve through the same theme normalizer used at mount time, reapply CSS variables to every package-owned mounted root, and must not call `restart()` or replace race state. Existing simulation state, timing order, selected driver, active penalties, camera state, speed setting, and pit intent state remain owned by the running app. `syncThemeFrom()` applies immediately, watches the configured attribute with `MutationObserver` when available, maps host attribute values through `options.map`, and returns a cleanup function.
- `initialCameraMode` accepts `'overview'`, `'leader'`, `'selected'`, `'driver'`, `'show-all'`, or `'pit'`; invalid values fall back to `'leader'`. The overview camera frames the active generated track bounds with package-owned padding and pit-lane extent. The driver camera follows the selected car from a lower screen anchor and rotates the world so the selected car points upward; its control is opt-in through `ui.driverCamera: true`, and `initialCameraMode: 'driver'` enables that control automatically. The pit camera frames the operational `track.pitLane` lane, boxes, service areas, and queue areas instead of the longer entry/exit access roads, zooms out when needed to keep that pit-lane work area inside the active race-view safe area, and its control is hidden/disabled if the active track has no pit lane. Zoom buttons and wheel zoom work in every camera mode, including overview, show-all, driver, and pit, but cannot zoom farther out than the active track frame.
- Camera controls default to external placement so they do not cover the race view. They can still be embedded in the race canvas by setting `ui.cameraControls: 'embedded'`, externally mounted, or omitted with `false`.

Strict action policy throws on missing or non-finite vehicle controls, while report policy records the error and releases stale manual controls so the built-in driver owns that physics step. `info.drivers[driverId]` exposes per-driver `terminated`, `truncated`, `endReason`, `episodeStep`, and `episodeId` for batched loops; selected-driver resets clear only selected driver truncation/termination and do not rewind global `info.step`. For scoped reset results, `info.controlledDrivers` matches the drivers present in `observation` and `metrics`, while `info.drivers` preserves episode state for all configured controlled drivers. Controlled drivers do not receive tire-threshold automatic pit calls; they request automatic pit service through `pitIntent`, may choose the target tire through `pitCompound`, and observe pit-lane/service/race-control state in `observation[driverId].object.self` and `.race`. `pitIntent: 0` is a no-op clear request and does not fail when pit stops are disabled. `self.onTrack` follows wheel-level legality, so track, kerb, and legal pit-lane/box surfaces are on-track while gravel/grass/barrier are off-track. Barrier-wall contact in both physics modes is measured against the rendered wall's inner face; contact marks the car destroyed/DNF, removes it from active collision/sensor participation, emits a `car-destroyed` event, and terminates that driver's episode with `endReason: 'destroyed'`. Opt-in stalled off-track DNF removes the car from the same active participation systems while keeping `destroyed: false` and terminates controlled-driver episodes with `endReason: 'stalled-off-track'` when `rules.modules.stalledDnf.enabled` is `true`. Reset is still an episode-boundary `resetDrivers()` call. Environment scenarios may set reset positions with `preset`, `placements`, and relative `traffic`; `resetDrivers(placements)` may reset selected controlled drivers between episodes without recreating the whole simulation. Partial `reset(options)` calls preserve omitted nested option groups while replacing arrays and explicit scenario placement maps. After placement, selected cars are classified by the same runoff/barrier rules before observations are returned, so cars already inside terminal barrier space report destroyed metrics and stable miss-valued rays instead of doing alive-car far-out ray scans. Both scenario placement and `resetDrivers()` are setup data, not policy actions. `participantInteractions` may make real physics cars non-colliding, sensor-hidden, non-blocking for pit occupancy, or excluded from race order, but those cars still live in `snapshot.cars` and move only through normal physics/control APIs. The `batch-training` profile is non-colliding, sensor-hidden, pit-non-blocking, excluded from race order, and still rendered. `replayGhosts` are separate trajectory-driven entities in `snapshot.replayGhosts`; they are visual/reference overlays and never enter car physics, timing, pit, order, or penalty systems. Replay ghosts are sensor-hidden unless their own sensor flags explicitly opt them into ray or nearby observations.
- Headless environments also accept an optional `externalRenderer` observer hook. It receives `{ snapshot, observation, meta }` on `reset`, `step`, and `resetDrivers`, so external tooling can stream authoritative frames to visualizers without letting that transport mutate simulation state.
- Controller loop code should use `createPaddockDriverControllerLoop()` instead of duplicating browser/headless stepping. Its controller context groups observations by controlled driver id, includes `orderedObservations` for direct batch tensor assembly, exposes metrics, events, cached specs, and reset-driver ids, and keeps per-driver resets as controller reset hooks when the runtime supports `resetDrivers()`. `previousActions` is the last action map actually applied before the current `actions`; on the first controlled frame after reset it is empty, and after repeated frames it reflects the prior physics step rather than pre-copying the current decision.

Ambiguous recovery, pit-connector, and pit-lane-origin rays use bounded sampled validation inside the ray-band tracer, and `precision: 'debug'` uses that same tracer path with extra sampled refinement for diagnostics. Only missing-index cases use the older sampled fallback path. This preserves model-facing distances without substituting debug-only refinement.

- Browser expert mode is opt-in with `expert: { enabled: true, controlledDrivers, frameSkip }`. It shares the environment episode lifecycle.

- Browser expert mode may opt into `expert.visualizeSensors: true` or `expert.visualizeSensors: { rays: true }`. When enabled, ray sensors render in the race canvas world layer from the selected controlled car by default, using the same observation result produced by explicit expert steps. The overlay draws a separate colored marker for each detected active channel on each ray, including road-edge, kerb, illegal surface, and car hits. Barrier walls are visible track geometry, not ray-hit markers, and browser components must not reintroduce a barrier ray label. Hosts may request `visualizeSensors: { rays: true, drivers: 'all' }` for the heavier all-controlled-car overlay or pass an explicit driver id list.

Recovery rays can also use the direct path when the indexed boundary is validated against driver-precision track state, including barrier-to-runoff illegal-surface recovery and off-track road/kerb re-entry. Low-curvature recovery and validation samples may reuse the origin segment to stay off generic nearest-track classification, while curved ambiguous recovery, pit-connector, and pit-lane-origin rays stay inside the ray-band tracer and use one bounded sampled validation pass for all requested road/surface channels instead of falling back to separate legacy road and surface scans. `precision: 'debug'` uses the same tracer-owned path with additional sampled refinement for clearly labeled diagnostics; only missing-index cases use the older sampled fallback path.

+Scratch-backed driver ray batches keep requested-channel dispatch in reusable scalar channel flags rather than rebuilding channel `Set` containers per ray. The indexed boundary traversal also reuses one query-index sample point across ray-grid steps instead of allocating temporary points. The runtime benchmark gate enforces zero channel-set allocations, stable channel-flag containers, and sample-point reuse for the common direct ray path.
When a full observation includes both `object` and `vector`, Policy Runner model inputs that need ray geometry use the observation object's actual `angleDegrees` and `lengthMeters`. Compact vector schemas intentionally carry ray channel values, not out-of-band ray geometry, so consumers with per-driver sensor overrides must read the active object observation or the exact per-driver spec instead of reconstructing layout from a default preset.
The model-facing sense proof boundary is documented in [Model Sense Contract](sense_contract.md). The executable contract test compares object observations against independent simulator-snapshot oracles, decodes vector entries by schema name, and checks compact vector-only output against full output for the same deterministic state. New model-facing sense fields must extend that oracle instead of relying only on snapshot or shape tests.

Endpoint-progress shortcut checks use precomputed route endpoint segment windows, while mid-connector points use bounded indexed route candidates without becoming full pit-lane queries. The runtime track-query benchmark explicitly probes those pit-road routes and requires direct connector scratch reuse, positive endpoint-window connector projections, zero connector full-route projection scans, grid hits, scratch reuse, precomputed route distances, zero cumulative-distance rebuilds, zero road-grid misses, and zero pit fallbacks.

`resetDrivers()` is part of episode control, not policy action. After reset placement, the environment immediately reclassifies the selected cars against the same runoff/barrier rules used during stepping before building observations.

Servers should read model inputs from `body.vectors[index]` where `body.driverIds[index]` is the driver being evaluated; `previousActions[index]` is a `[steering, throttle, brake]` tuple for the same driver, and `metrics[index]` follows the reset-time `metricFields` order. Rich observation objects and schemas are no longer repeated on every decision. This is a breaking transport contract for policy-server integrations. There is no rich per-decision fallback in Policy Runner server mode; use object/full observation output only in local JavaScript, headless, debug, or explicit state/export flows.

+Those numbers are hardware- and track-dependent, but the relative result is the useful guidance: compact state/observation output reduces serialization/allocation overhead, indexed track queries prevent off-track recovery rays from becoming the dominant cost center in real environment loops, and direct indexed ray-band intersections keep common driver-precision road/surface rays off the expensive sampled nearest-query path. The high-volume seed sweep covered 69 procedural seeds, 447,120 ray builds, 3,129,840 individual rays, 149,040 wheel-surface classifications, and 1,380 environment steps with zero invalid ray payloads, zero invalid environment observations, zero invalid wheel classifications, and zero nearest/pit fallbacks.

+There is one deliberate microbenchmark caveat: adversarial standalone `buildRaySensors()` sweeps that force normal-profile rays from kerb, gravel, and runoff poses on complex generated tracks can be slower than 3.0.0 because the current path performs more bounded indexed exact validation to preserve driver-precision surface semantics. On the worst checked seeds, real environment stepping still measured faster than 3.0.0.

+# Troubleshooting
+
+Use this when a host integration or package release check fails.
+
+## Raw Node Import Fails
+
+Do not use this as the main package check:
+
+```bash
+node -e "import('@inventure71/paddockjs')"
+```
+
+The root package is browser-oriented and imports CSS/assets. Use the browser-free subpaths in Node:
+
+```js
+import { createPaddockEnvironment } from '@inventure71/paddockjs/environment';
+import { DriverData } from '@inventure71/paddockjs/data';
+```
+
+## CSS Is Missing
+
+Import the package stylesheet from a browser entry when the host bundler does not extract it automatically:
+
+```js
+import '@inventure71/paddockjs/styles.css';
+```
+
+If styles are present but the simulator is squeezed or overlapping, check the host container size before changing package internals. PaddockJS supports roots at least `320px` wide and shows an `Unsupported size` placeholder below supported bounds.
+
+## Assets Do Not Resolve
+
+PaddockJS owns default simulator assets. Hosts should not copy them manually. In the package repo, verify publish contents with:
+
+```bash
+npm run pack:dry
+```
+
+In a host app, verify through the host's browser build rather than a raw Node import.
+
+## Simulator Looks Frozen
+
+Check whether browser expert mode is enabled:
+
+```js
+expert: { enabled: true, controlledDrivers: ['budget'] }
+```
+
+Expert mode intentionally waits for `simulator.expert.step(actions)`. Basic website mounts should omit `expert` unless they are playing back a model or debugging policy observations.
+
+## Policy Server Receives No Observations
+
+Policy Runner server mode uses protocol version `2`. `/policy/decide-batch`
+receives aligned compact arrays, not rich `observations`. Static specs,
+configuration, `previousActionFields`, and `metricFields` are sent once to
+`/policy/reset`, so servers should cache `observationSpec` and read model
+inputs from `body.vectors[index]` for `body.driverIds[index]` during decisions.
+
+## Theme Toggle Resets The Race
+
+Use runtime theme APIs instead of restarting:
+
+```js
+simulator.setThemeMode('dark');
+simulator.setTheme({ tokens: { primary: '#008c55' } });
+```
+
+`restart(nextOptions)` is for race/data/seed changes, not normal light/dark presentation sync.
+
+## 3.x Upgrade Symptoms
+
+- Remove host usage of `trackQueryIndex`; indexed track queries are package internals.
+- Replace old strict physics usage with `physicsMode: 'advanced'`, or omit `physicsMode` for the default `arcade` mode.
+- Use `@inventure71/paddockjs/environment` for headless simulation.
+- Use `@inventure71/paddockjs/data` for CSS-free data/tooling imports.

+# Upgrading Hosts To PaddockJS 4.x
+
+Use this checklist when moving a browser host website from 2.x-era PaddockJS usage to the 4.x package API.
+
+1. Install the 4.x package:
+
+ ```bash
+ npm install @inventure71/paddockjs@4
+ ```
+
+2. Import package CSS intentionally anywhere browser mounts are used:
+
+ ```js
+ import '@inventure71/paddockjs/styles.css';
+ ```
+
+ The stylesheet is scoped to PaddockJS roots and uses system fonts by default. Load any branded web fonts from the host app instead of relying on package-side remote font imports.
+
+3. Remove host usage of `trackQueryIndex`. Track query indexing is package-owned and internal in 4.x.
+
+4. Replace `physicsMode: 'simulator'` with `physicsMode: 'advanced'`, or omit `physicsMode` to keep the default `arcade` mode.
+
+5. Decide how the host should theme the simulator. Use mount-time `theme` for defaults, then use `simulator.setThemeMode(mode)` or `simulator.setTheme(theme)` for site light/dark toggles. Do not call `restart({ theme })` only to change presentation.
+
+6. Reuse public theme helpers instead of copying CSS variable names:
+
+ ```js
+ import {
+ PADDOCK_THEME_CSS_VARIABLES,
+ PADDOCK_THEME_TOKEN_KEYS,
+ applyPaddockTheme,
+ resolvePaddockTheme,
+ } from '@inventure71/paddockjs';
+ ```
+
+7. Decide whether the host should enable the driver camera with `ui.driverCamera: true` or `initialCameraMode: 'driver'`.
+
+8. Use `@inventure71/paddockjs/environment` for browser-free simulation/training imports.
+
+9. Use `@inventure71/paddockjs/data` for CSS-free data/helper imports such as `DriverData`, `normalizeSimulatorDrivers`, `createProceduralTrack`, and speed conversion helpers.
+
+10. Rebuild the host bundle and browser-smoke the host page, including theme toggles, selected-driver surfaces, and any composable mount roots.
