Add MoonLive palettes, perceptual brightness, and QuinLED Dig-Next-2 support - #93
Merged
Conversation
Palettes can now be scripts: a .mlp recomputes its sixteen entries every frame, so a palette can follow audio or drift where a gradient stop list is frozen. They are chosen from the same picker as the sixty built-ins. Brightness now follows the CIE 1931 lightness curve, so a slider at half reads as half. Core - /api/scripts served only three of the five script roles, so services and palettes reached no picker and could never be downloaded. Light domain - MoonLivePalette: the fifth MoonLive binding, filling a scratch palette per frame and swapping it whole, so a sampler sees old or new, never both. - Scripted palettes sort LAST, after the built-ins: a palette selection is an index that is persisted, rides seg[0].pal over the WLED API, and is rendered positionally by Home Assistant, so only the scripted tail may renumber. - LivePalettes references its publisher's arrays rather than copying them, and publication moved from defineControls() to prepare(). /api/modules builds a throwaway module, runs defineControls() and destroys it; that probe took the seam and died holding it, so /api/state read freed memory and crashed (SIGSEGV in strlen) on any device carrying .mlp files. clear() now takes the caller's array, so a departing publisher can only ever unpublish itself. - The palette control is sized from the instance's own scan, not the seam: seam-sized, it capped at the built-ins and silently rejected every scripted index. - Correction: white balance and brightness stay linear gains, the perceptual curve applies last before quantize (Cie, Gamma22, Gamma28, Linear). UI - The palette dropdown is now the shared picker: search, emoji chips and the gradient swatch column, rather than a second hand-rolled list. Catalog palettes the device does not hold yet appear alongside the local ones and download on select, the contract every other MoonLive role already had; their swatch is a dashed placeholder, because a script has no colors until it runs. Tests - Three regressions pin the seam: a departing publisher cannot unpublish its successor, an unconditional clear detaches whoever owns it, and a probe module leaves the seam exactly as it found it. Docs/CI - Desktop first is now a rule in CLAUDE.md: verify on the desktop before any ESP32 build or flash. Two portability bugs here were invisible to clang and fatal under the ESP32 toolchain (a uint32_t callback parameter spelled size_t, and a %s snprintf GCC cannot prove fits), so the palette feature had never compiled for any device. Gates: esp32 and esp32s3-n16r8 rebuilt; esp32s3-n8r8 and esp32s31 binaries NOT rebuilt (stopped at the product owner's request to commit) — the next commit covers the download path and rebuilds all four. Improv smoke test not run: the diff does not touch the provisioning path. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

Clear MoonLivePalette::active_ from both Drivers::release() and ~Drivers(). LivePalettes::clear(livePtrs_) clears a different seam, and MoonModule::release() does not visit the paletteScriptModule_ member. If Drivers is released or destroyed while the instance is active, Effects::tick() can call active_->tick() through a dangling pointer. Clear it only when it equals &paletteScriptModule_.

A new esp32-pico firmware brings up the QuinLED Dig-Next-2 (ESP32-PICO-V3-02: 8 MB embedded flash, 2 MB embedded PSRAM) with its two LED outputs and its four relay channels. Scripted palettes now reach Home Assistant, and two static seams that pointed into a departed module are closed. Core - The WLED shim served `palcount` and `palettes[]` as the built-ins alone while the `palette` control already accepted the scripted indices above them, so a scripted palette was unnameable and unselectable from Home Assistant. Both now come from one `paletteCount()`, so the count cannot drift from the array it describes. Light domain - MoonLivePalette's active-instance pointer is a static INTO a Drivers member and `Effects::tick` dereferences it every frame, so a released or destroyed Drivers left the render path running a script in freed memory. It now detaches the same ownership-checked way LivePalettes does, and frees the compiled script with it. - ParallelLedDriver refuses a bus pin the chip has wired to flash or PSRAM before touching the bus, with a status naming the GPIO. The platform already knew those pins; this path was not asking. - The i80 WR/DC defaults are chosen per chip: 10/11 are free on the S3 they were picked on and are the flash bus on a classic ESP32. UI - A downloaded palette that has not appeared in the list yet is retried once and then reported. It used to skip selection silently, so a successful download looked like nothing happening. - beat-flash.mlp wraps its hue with mod(): byteArg clamps at 255, so a high `hue` setting flattened the gradient across the upper entries. Tests - The i80 clock/DC defaults never land on a chip's flash pins; a reserved bus pin is refused rather than routed; the WLED palette list and its count cover the scripted palettes. unit_PartitionTables now validates the 8 MB table. Docs/CI - Backlogged by name: ParallelLedDriver hangs inside esp_lcd_new_i80_bus on classic ESP32 (IDF v6.1-rc1). Traced to the call itself, which never returns. Ruled out on the bench: frame size, duplicate pins parked on WR, and the WR/DC pin choice. It stays registered and selectable, since hiding it would remove the one path anyone can retest with, and it is correct on every LCD_CAM chip. Reviews - 🐇 hue clamped past 255 in beat-flash.mlp: done, via mod() (MoonLive has no `%` operator, so the suggested form would not compile). - 🐇 MoonLivePalette::active_ not cleared on release/destroy (raised twice, one defect): done, both paths. - 🐇 silent skip when the post-download index is missing: done, retry then report (there is no rebuild-completion signal to hook, so it is a bounded retry rather than an event). - 🐇 palcount/paletteNames miss the live palettes: done, plus a test pinning the two together. Gates: ESP32 binaries NOT rebuilt for any of the five variants (stale against this diff) - the next commit rebuilds them. Improv smoke test PASSED on the Dig-Next-2 over USB. Scenario p50 moves are rolling-window shift, not regression: the retained outliers are unchanged and nothing here touches the audio or layout tick path.

Keep the device model chip value at the family level.
chipFamily() normalizes ESP32-PICO-V3-02 to "ESP32", while applyDetectedChip() requires an exact chip match. The "ESP32-PICO-V3-02" value therefore omits QuinLED Dig-Next-2 from the detected-chip board list.

Validate the i80 WR and DC pins as well.
busPinList() does not represent every GPIO used by the i80 bus. In a full-width direct configuration, it contains only data pins, so clockPin is not included as padding. dcPin is never included. src/light/drivers/MultiPinLedDriver.h still routes both controls through addBusControls() at Lines 160-163. A configuration such as dcPin=6 on classic ESP32 can therefore pass this scan and route a control signal onto a flash pin. Extend the reserved-pin validation contract to include clockPin and dcPin, then add a full-width regression near Lines 687-709 of test/unit/light/unit_ParallelLedDriver_pinexpander.cpp.

Repaint the palette trigger after a downloaded palette is selected.
After finding the new palette's index, this code sets fresh.dataset.value = idx but does not repaint the trigger's swatch or name. Because wrap.dataset.value now equals the soon-to-arrive ctrl.value, the WS patch path (case "palette" in updateModuleControls) will see no mismatch and will skip repainting. The trigger keeps showing the previously-selected palette's name and swatch until an unrelated full re-render happens, even though the device is now running the newly selected scripted palette.

Fixes four review findings on the prior commit's work: a device-model field
that broke chip auto-detection, a script-engine leak on teardown, a reserved-
pin gap in the i80 bus init, and a stale UI trigger after a palette download.
Core
- HttpServerModule's WLED-state palette clamp now checks the full palette
count (built-ins plus scripted), matching the range paletteNames() serves.
Light domain
- ParallelLedDriver's reserved-pin refusal now covers the i80 clockPin/dcPin
controls too, via validateBusFatal(): the lane sweep alone missed a
full-width bus, where there's no spare lane left to park WR on and dcPin
never rides the lane list at all. Both status buffers merged into one
member (mutually exclusive cold-path messages; the classic ESP32 has little
RAM to spend on two).
- Drivers' destructor now releases the scripted-palette engine, not just its
static seam pointer, so a Drivers torn down without release() (a stack
instance, a test) doesn't leak the compiled script.
- deviceModels.json's Dig-Next-2 entry uses the chip FAMILY value ("ESP32")
applyDetectedChip() matches against, not the specific ESP32-PICO-V3-02
string, which made the board unreachable by auto-detect.
UI
- The palette picker's download-then-select path repaints the trigger
(swatch/name) from the freshly-fetched control and stamps dragTs, matching
what the already-local selection path does. It previously left the old
palette showing until an unrelated render happened to run.
- remotePalettes() normalizes the .mlp suffix on both sides of its
already-downloaded check, not just the catalog side, so a downloaded
palette no longer doubles up as an offer to download it again.
Tests
- A full-width bus (8 pins, no spare lane) with clockPin/dcPin on a reserved
GPIO is refused, pinning the gap validateBusFatal() closes.
Docs/CI
- Pre-merge run over the whole branch diff (59 files vs main): every commit-
table check plus the Reviewer agent (sonnet; Fable/Opus reporting service
issues). Reviewer found no boundary, hot-path, duplication, or bloat
findings against CLAUDE.md's Merge criteria.
- Desktop build's -Wfunction-effects count grew (this branch adds palette
builtins to the same lazy-init/call-chain patterns already backlogged in
backlog-core.md, which explicitly notes this class "reports these but
never fails a build"); the authoritative hot-path check confirms zero new
entries against the frozen baseline.
- No-backend build's 16 pre-existing failures (compile() has no non-JIT
fallback) are confirmed present on unmodified main via an isolated clone,
not introduced by this branch.

What this is
Three things, one branch: scripted palettes as the fifth MoonLive binding, a CIE 1931 perceptual brightness curve, and QuinLED Dig-Next-2 support on a new
esp32-picofirmware. Along the way it closes two dangling-static-seam crashes, an ESP32-only build break, and two rounds of CodeRabbit findings.MoonLive palettes (
.mlp)A palette that is CODE rather than data. A
.mlpscript fills the 16 active palette entries once per frame, so a palette can respond to audio, drift over time, or compute from an algorithm. A gradient stop list cannot express any of that: it is frozen the moment it is saved.The idea is MoonLight's. Their implementation runs a scripted palette in a separate FreeRTOS task at 8 KB of stack plus an on-device compiler, which is why their live scripts need a PSRAM-class board. We already JIT to native code and run every binding inline on the render thread, so
.mlpis the fifth binding beside.mle/.mll/.mlm/.mls: the sameMoonLiveScriptmember, the samesync()on prepare, the same file picker. A role, not a mechanism.The cost is what makes it work: 16 entries once per frame, not per light. A 16x16 grid runs an effect body 256 times a frame; a
.mlpruns 16 iterations whatever the rig size.Five ship:
beat-flash,drift,fire,spectrum,temperature.Ordering is load-bearing. Scripted palettes sort LAST, after the sixty built-ins. A palette selection is an index: it is persisted, it rides
seg[0].palover the WLED API, and Home Assistant's integration renderspaletteNamespositionally. Putting scripted ones first would mean saving one more.mlpsilently turns a storedpalette: 12into palette 11. Last means only the scripted tail renumbers. The WLED shim'spalcountandpalettes[]now include that tail, from onepaletteCount(), so HA can name and select a scripted palette.Perceptual brightness
Brightness now follows the CIE 1931 lightness curve (CIE 15 / ISO 11664-4), so a slider at half reads as half. White balance and brightness stay linear gains; the perceptual curve applies last, before quantize. Selectable: CIE, gamma 2.2, gamma 2.8, linear. The implementation uses the standard's 903.3 / 116 constants, not the widely copied 902.3 / 119 typo.
QuinLED Dig-Next-2
New
esp32-picofirmware for the ESP32-PICO-V3-02 (classic ESP32 SiP: 8 MB embedded flash, 2 MB embedded quad PSRAM). Its own variant because the base assumes 4 MB and no PSRAM. MoonBase layout: factory recovery image, one 3 MB app slot, 4 MB LittleFS. The device model carries the two LED outputs (GPIO 2, 4), the four relay channels (5, 20, 21, 22, matching the vendor pinout and MoonLight's map), and a 460800 flash baud because the board's USB bridge drops the 921600 default mid-flash.Verified on two boards: Improv provisioning passes, relays follow master power, RMT renders. The onboard microphone is PDM (GPIO 7/8, no SCK), which the I2S path does not support; left under
planned.ParallelLedDriver hangs on this chip, inside
esp_lcd_new_i80_busitself, which never returns (watchdog reset, both CPUs at the same PC, no panic). Traced with a log line before and after the call. Ruled out on the bench: frame size, duplicate pins parked on WR, and the WR/DC pin choice. Backlogged by name inbacklog-light.md; the driver stays registered and selectable so it can be retested, and it is correct on every LCD_CAM chip. Two guards did come out of the investigation:ParallelLedDriverrefuses any bus pin the chip wires to flash/PSRAM (the platform already knew those pins; the bus path was not asking), and the i80 WR/DC defaults are chosen per chip, since 10/11 are free on the S3 and are the flash bus on a classic ESP32.The crashes this uncovered
LivePalettesreferences its publisher's arrays rather than copying them (~640 bytes of static RAM saved on every board). Publication sat indefineControls(), but/api/modulesbuilds a throwaway module, runsdefineControls(), and destroys it. That probe took the seam and died holding it, so/api/stateread freed memory and crashed with a SIGSEGV instrlenon any device carrying.mlpfiles. Fixed by publishing fromprepare(), which only a scheduler-mounted module runs, and givingclear()the caller's array so a departing publisher can only ever unpublish itself.MoonLivePalette::active_is the same shape (a static into a Drivers member thatEffects::tickdereferences every frame) and got the same fix, plus the engine is now freed on release and destruction.A third, caught by CI's ASan and TSan lanes: the reserved-pin refusal formatted its status into a stack buffer, and
setStatusstores the pointer rather than copying. Now a single member buffer shared by the driver's formatted statuses.UI
The palette dropdown is now the shared picker (search, emoji chips, gradient swatch column) rather than a second hand-rolled list. Catalog palettes the device does not hold yet appear alongside the local ones and download on select, the contract every other MoonLive role already had; their swatch is a dashed placeholder, because a script has no colors until it runs. After a download the trigger repaints from the freshly fetched control, and a palette that has not appeared yet is retried once and then reported rather than silently skipped.
/api/scriptsserved only three of the five script roles, so services and palettes reached no picker and could never be downloaded at all.Two portability bugs, and a new rule
A
uint32_tcallback parameter spelledsize_t, and a%ssnprintf GCC cannot prove fits. Both invisible to clang, both fatal under the ESP32 toolchain: the palette feature had never compiled for any device. Desktop first is now a rule in CLAUDE.md: verify on the desktop before any ESP32 build or flash.Reviews
Two CodeRabbit rounds, every finding processed (9 fixed, 0 skipped; two applied in a different form than suggested, both recorded in the commit messages). Pre-merge Reviewer agent over the whole 59-file branch diff against CLAUDE.md's Merge criteria: no boundary, hot-path, duplication, or bloat findings.
Verification
Desktop: 1710 unit cases, 143 Python, 121 JS, 20 scenarios (observations recorded), zero-warning build (only the backlogged
-Wfunction-effectsclass appears; the hot-path check confirms zero new against its baseline). The no-backend build carries 16 pre-existing failures that are identical on unmodifiedmain(compile()has no non-JIT fallback), confirmed in an isolated clone.Hardware: S31 (palettes catalog, seam stability across probe endpoints), two Dig-Next-2 boards (Improv, relays, RMT, the ParallelLed hang reproduced with serial capture).
Open gate: the ESP32 binaries are stale against the final diff.
esp32-picoandesp32s31were built and flashed during the work, but no variant was rebuilt after the last two commits.🤖 Generated with Claude Code
