Removed all #ifdef USE_SDL guards, -DUSE_SDL, -lSDL3, SDL3/SDL.h
include. SDL3 code always compiles with void* types and dlsym
function pointers. No compile-time or link-time SDL dependency.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

All SDL3 functions loaded via dlsym at runtime instead of link-time
dependency. Binary starts and works on any hardware:
- SDL3 libs present + working GPU: GPU-accelerated rendering
- SDL3 libs missing or DRI broken: graceful fallback to DRM/fbdev
- Probe runs in child process to catch Mesa/GBM segfaults

No more -lSDL3 in LDFLAGS. Oven builds re-enabled with USE_SDL=1.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

Binary crash from linker loading libSDL3→libgbm→iris_dri.so before
main(). Needs dlsym-based loading to avoid link-time dep. SDL off
in oven builds for now. Probe improvements kept for future use.

- docker-build.sh: transitive dep loop now includes lib64/dri/*.so
(DRI drivers have many deps that were never resolved)
- init: set LD_LIBRARY_PATH, LIBGL_DRIVERS_PATH, GBM_DRIVERS_PATH,
MESA_LOADER_DRIVER_OVERRIDE=iris for Intel UHD 615
- AC_BUILD_SDL now defaults to 0; this fix prepares for re-enabling

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

SDL3/GBM/Mesa DRI libs caused immediate segfault on ThinkPad 11e
(libgbm.so cannot open DRI driver). Build now defaults to DRM-only
(AC_BUILD_SDL=0). SDL can be re-enabled per-build with AC_BUILD_SDL=1.

JS_NewObjectClass(painting_class_id) for nopaint buffer/painting
meant GC would call fb_destroy() on runtime-owned framebuffers.
Now the finalizer skips buffers that match current_rt->nopaint_*.

command -v returns exit 1 when tool not found, which set -e catches.
Also [ -n "" ] && cp pattern exits 1 with set -e. Fixed both with
|| true guards and if/then instead of && chains.

partprobe was never in initramfs — all partition table re-reads
after sfdisk were silently failing, causing mkfs.vfat to fail on
NVMe because /dev/nvme0n1p1 didn't exist yet.

Now: partprobe bundled, plus blockdev/busybox/sfdisk --verify as
fallbacks, with 5s polling loop for device node appearance.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

Install: wait up to 5s for partition device node after repartitioning
with repeated partprobe probes. The 500ms wait was insufficient for
NVMe devices — mkfs.vfat failed because /dev/nvme0n1p1 didn't exist
yet after sfdisk recreated the partition table.

WiFi: save captive portal HTML to /mnt/portal_page.html for debugging
Getty ClearPass portals.

- Dockerfile.builder: install ccache
- docker-build.sh: CC="ccache gcc" for binary + kernel builds,
skip make clean when ccache available, log hit rate at end
- native-builder.mjs: mount persistent ac-os-ccache Docker volume
- First build: same ~25min (cold cache). Subsequent: ~2-5min
(only recompiles changed files, rest served from cache)

Migrated from V1 (Node.js/SQLite on silo) to V2 (Go/Postgres on lith).
All 8 channels and 17 playlists migrated. Landing page updated with V2
API endpoints, DP-1 protocol section, Feral File attribution, and
iframe lifecycle tied to AC boot-log ready signal. KidLisp KIDLISP_COLORS
synced with full cssColors map + c0-c150 index shortnames + patterns.

- net.rewrite/net.log stubs
- pppline(points): polyline drawing on ink chain
- nopaint.mjs module stub: all exports stubbed for import resolution

Runtime-level persistent painting canvas that survives piece swaps:
- system.painting: persistent ACFramebuffer, accessible from any piece
- system.nopaint: state machine (is/cancelStroke), brush position, buffer
- Auto-creates painting+buffer when piece exports system="nopaint"
- Touch→paint→bake lifecycle handled in C (js_call_act/js_call_paint)
- Painting composited as background before piece paint()
- Buffer baked onto painting on stroke lift, then cleared
- Non-nopaint pieces (prompt) can access system.painting to show it

New rendering primitives:
- page(painting) switches render target, returns chainable proxy
- paste(painting, dx, dy) alpha-composites buffers
- painting.pixels Uint8Array for direct pixel access
- line(x0,y0,x1,y1,thickness) thick lines via filled circles
- graph_line_thick() in graph.c

Includes painting.mjs test piece for standalone testing.

Painting system:
- page(painting) switches render target, returns chainable proxy
- paste(painting, dx, dy) alpha-composites onto current target
- painting(w,h,cb) now exposes .pixels Uint8Array for direct access
- graph_line_thick() for variable-width brush strokes
- line(x0,y0,x1,y1,thickness) JS API with 5th thickness param
- New painting.mjs piece: persistent canvas, freehand line brush,
color cycling (c key), clear (n key), scroll thickness

DJ fixes:
- Speed control moved to audio callback with linear interpolation
(was broken in decoder resampler) — scratching actually works
- Negative speed support (-4x to +4x) for reverse scratching
- TTS fixed: was calling tts.speak() but API is sound.speak()

WiFi: ClearPass captive portal cmd=authenticate strategy
ac-os: strip @ prefix from handle, USE_SDL defaults off

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

- audio: speed control now in audio callback with linear interpolation
instead of broken resampler approach — scratching actually works
- audio-decode: allow negative speed (-4 to +4), init ring_frac,
decoder always decodes at 1x (speed applied at playback)
- wifi: add ClearPass cmd=authenticate strategy for Getty portals,
add POST with accept params, add -k flag for HTTPS portals
- dj.mjs: TTS was calling tts.speak() but API exposes sound.speak()
— replaced all tts refs with sound.speak via say() helper
- ac-os: strip @ prefix from handle to prevent @@jeffrey double prefix

Scale two-pass Gaussian blur strength by 1/3 to match the old single-pass
behavior — blur(5) was producing ~3x stronger output after the rewrite,
breaking pieces like $4bb that rely on specific blur levels.

Re-enable console.warn for network errors in fetchCachedCode so embed
failures are visible in devtools instead of silently swallowed.

- All colors now use __theme (T.bg, T.fg, T.bar, T.border, T.accent,
T.ok, T.warn) — auto light/dark based on time of day
- USB plug: "USB DJ on" TTS, auto-scan + play first track
- USB unplug: "USB DJ off" TTS, stop playback, clear track list

GettyLink returned HTTP 200 with a login page but the old code just
re-fetched the connectivity check URL. New flow:
1. Detect portal (connectivity check != 204)
2. Follow redirects, save portal page HTML
3. Extract form action URL from the page
4. POST to the form action (accepts terms on most portals)
5. Re-check connectivity after 1s propagation delay

Logs from USB showed: portal detected → auto-accept did nothing →
WebSocket connections got 302 Captive Portal endlessly.

Scratch:
- Radial drag around platter center (atan2 angular delta)
- Modulates playback speed (-3x to 3x) based on drag direction
- Release returns to normal speed or pauses
- Visual rotation follows actual speed including reverse

Controls:
- Left/right arrows: speed/stretch (pitch fader style)
- Up/down arrows: seek
- Z: reset to 1x speed

Also skip dot-prefixed files (._ metadata from macOS)

- Touch/drag anywhere to scratch (drag down=forward, up=rewind)
- Big spinning platter with grooves, needle, label
- N/P: next/prev track, Space: play/pause, R: rescan
- Auto-advance to next track when current ends
- USB hot-plug with TTS
- Theme-aware colors

notepat.mjs was calling wifi.scan() every 120 frames (2s) which
triggered iw scan causing 65ms+ frame drops. Reduced to every
1800 frames (30s). WiFi re-enabled in C init.

additional creds loaded from /mnt/wifi_creds.json on boot.

- WiFi fully disabled — notepat.mjs calls wifi.scan every 120 frames
causing 65ms+ frame drops from iw scan. Will re-enable once scan
is non-blocking.
- DJ turntable scratch is now mouse/touchpad interactive:
- Touch/click platter to grab it, drag to scratch
- Drag down = forward, up = rewind (100px = 2s seek)
- Bigger platters with groove rings and spinning needle
- Visual feedback: platter highlights, needle follows position

mountMusic() was mounting /dev/sda2 (boot USB data partition) as

- Adds ext4 and ntfs3 filesystem support
- Logs each mount attempt for debugging

- Hitbox ring (r=7) drawn around all alive players
- Spectators use server positions for all players (no local prediction)
- Removed debug clientlog relay
