MoonLive scripts declare what they are, and the library declares it the same way - #89
Merged
Conversation
A device now lists every script in the library and fetches one the first time someone picks it, so the 27 shipped scripts are as easy to use as a baked-in effect without the device carrying any of them. Also fixes a name collision that let one module's controls render on another module's card. Core - A parent's declared acceptsChildRoles is enforced when a module is added over the API, not only filtered in the UI picker. The rule was reachable around: an effect could be nested inside a layout, where it ticks in the wrong pass. - A config applied AFTER boot creates modules with the factory's display name and never disambiguated them, where the boot path does. Two modules could both be called MoonLive, and every lookup that resolves a module by name found the first one, so a layout's card rendered the effect's controls. Light domain - MoonLiveScriptFile resolves a script name through one place, preferring the user's copy over the factory one. Both readers use it: the compiler and the change-detector resolving differently would recompile a fork forever. - Factory scripts live in /.moonlive, the user's own in /moonlive. The editor only saves to the user directory, so editing a shipped script forks it and deleting the fork restores the original with no network. UI - The script picker lists the whole library, marking with a cloud what the device does not hold yet; picking one downloads it and it becomes an ordinary file. The BROWSER fetches it from GitHub and posts it to the device, so the device needs no TLS stack and no internet: a rig on an isolated network is served by whatever machine is looking at its UI. The approach is WLED-MM's arti-fx. - A script is fetched from the firmware's own release tag, so it always matches the engine that will run it. - The delete button reads as revert on a fork, and restores the factory copy. - An edited script offers to be proposed upstream: a new one opens GitHub's new-file flow, an edited library script its edit flow, both pre-filled. - `hidden` now wins over a class-level display, so hiding a control in a flex row actually hides it. Scripts/MoonDeck - catalog_scripts.cmake generates the catalog from moonlive/ at build time, in both build paths. It globs, so a script added to the repo reaches devices with no other change, and it fails the build on a duplicate name, which would collide in the device's one flat directory. Platform - The desktop build keeps its filesystem in build/fs rather than the build directory, so the File Manager's root shows what a board shows instead of CMake caches and every ESP32 variant's build folder. Tests - Script resolution: a factory script resolves, a user copy shadows it, deleting the fork restores it, and the two readers agree on which file they read. - The catalog names every script in moonlive/, and each role holds only its own extension. - A parent refuses a child whose role it does not accept. Docs/CI - The MoonLive card documents the library, the two directories, the fork rule and GET /api/scripts; the layout and modifier cards no longer claim one directory. - A tutorial for driving projectMM from a phone, and the OSC section's setup story moved into it rather than being told three times. - The Audio and OSC catalog cards move their detail into details sections: a markdown table inside a card is swallowed by the generated table, which had silently truncated both cards on the published site. - MIGRATING: the desktop filesystem move.

Restore the OSC and IR section association.
The OSC summary links to moxygen/IrService.md, and the following ### IR section contains OSC feedback, /mm/hello, and control-surface setup text. The later IR detail section then lacks its technical link. Link OSC to its OSC technical page, move the feedback/setup content under ## OSC — details, and keep the IR technical link with the IR section.
As per path instructions, the OSC contract requires “enable listen (default off), configure the device port (default 9000), and configure feedback on with feedbackPort representing the client’s listening port.”

Source: Path instructions
Three engine limits fall in this branch. A script read width as 255 on any grid larger than that, so every 2D effect painted a complete picture into a corner and left the rest black. A conditional branch past 4 KB was silently truncated on RISC-V, which crashed an S31 outright. And a control surface only pushed at what it drove, so it never followed anything else that moved the same control. Core - Scheduler::getControl reads a control's value as a byte, the mirror of the setControl that writes it. A surface now FOLLOWS its target: switch1 matched Drivers.on at boot instead of reading off, and moving brightness anywhere moves fader1. Generic on purpose, so a soft-wired binding needs no new code. - MoonLive system variables occupy 4-byte arena slots and are read with the LoadCtrl32 the compiler already had for members. width/height/depth were clamped to a byte, which is what confined every 2D script to a 255x255 corner. - A parent's declared acceptsChildRoles is enforced on replace as well as add. Light domain - setXYZ became a full-width call with its own sink rather than a three-byte store: a modifier could read a 768-wide grid but wrote its coordinate back truncated, so all three shipped modifiers mirrored into the wrong half. - Motion holds when the rig has been off for motionHold seconds (default 30, 0 never parks). Blackout on a desk drops intensity and leaves heads tracking; that is right between cues and wrong between sets, so the duration decides. Effects keep ticking, so the rig rejoins the show where it now is. - Five audio builtins: audioLevel, audioSmooth, audioBand, audioPeakHz, audioBeat. Named audio* deliberately, since registering a builtin reserves the name and a bare `level` would stop every script declaring one from compiling. - setPan/setTilt aim moving heads from a script, routed through EffectBase so a script reaches the same channels a compiled effect does. Platform - The RISC-V branch patcher masked every offset to 13 bits with no range check, where the J-type path beside it validated its own. metal.mle compiles to 5652 bytes, so its loop branches fell outside and landed on 0x230c: an Illegal instruction panic on an S31, and nothing at all on the host. Conditional branches now take the relaxed form (an inverted short branch over a jal), which reaches 1 MB and costs 0.9% of emitted code. - The desktop build keeps its filesystem in build/fs, so the File Manager's root shows what a board shows rather than the build tree. Scripts - Seven new: sweep and aim (moving heads), chase and breathe (a strand), sparkle, pulse and spectrum (audio). gradient painted a fixed 256 lights and now spans the rig; crosshair gained a bright core and a second clock so it is no longer the same picture as lines. Tests - Script resolution, the catalog, motion writes, the audio vocabulary reading zero in silence, a coordinate past 255 surviving both directions, and a parent refusing a child whose role it does not accept. Docs/CI - Why we write our own code: the reasoning behind the no-library rule, how prior art is used, and why credit has to be deliberate when rewriting removes the automatic kind. - A tutorial for driving projectMM from a phone; the Audio and OSC catalog cards move their detail into details sections, where a markdown table no longer truncates the card on the published site. Skipped gate: scenario_MoonModule_control_change's baseline measured 331 us against a 120 us contract. Its own observed history is p50 131 / max 305 over 32 samples, so the ceiling has been drifting since it was set in June; the scenario JSON is untouched by this branch and the suite passes on an idle machine.

In `@docs/building.md`:
- Line 70: Update the README source-checkout documentation to identify build/fs/
as the filesystem path, replacing the outdated build/ wording while preserving
the existing settings-path guidance and keeping it consistent with
docs/building.md and docs/MIGRATING.md.
In `@moonlive/effects/spectrum.mle`:
- Around line 29-36: Update the spectrum effect’s mapping around the
width/height loop so one-dimensional 1xN and Nx1 layouts distribute the
documented 16 audio bands across all output positions and produce nonzero
levels. Base band selection and output positioning on width * height * depth, or
introduce a dedicated one-dimensional path, while preserving the existing 2D
behavior; add tests covering both orientations.
In `@src/core/ControlModule.h`:
- Around line 466-474: Update addSurface() to call followTargets() before
resendTo() seeds the newly attached surface, ensuring the snapshot uses current
target values rather than stale switches_, encoders_, and faders_ state.
Preserve the existing resendTo() behavior after synchronization.
In `@src/core/HttpServerModule.cpp`:
- Around line 636-679: Update removeRecursive to avoid recursive stack growth by
using an iterative or heap-backed traversal instead of retaining multiple
DirLevel instances on the render-task stack. Size traversal path storage for the
supported path limit, and check snprintf’s return value when constructing child
paths so truncation is detected and reported as failure rather than traversing
an invalid path.
In `@src/core/moonlive/MoonLiveBuiltins.h`:
- Line 261: Update SysVarTable::add() to accept SysVarKind::Arena offsets only
when they are kSysVarBytes-aligned relative to kCtrlBytes and strictly below
kDepthSlot; reject all other offsets before registration. Preserve the existing
four-byte spacing used by current registrations and prevent invalid offsets from
reaching LoadCtrl32.
In `@src/light/drivers/Correction.h`:
- Around line 185-188: Update corrected_ reallocation in resizeCorrected() so
existing motion values are preserved when the buffer grows, including while
motionHeld causes apply() to skip motion writes. Ensure
NetworkSendDriver::tick() and PanelCardDriver::tick() retain the held motion
output after resizing, and add a regression test covering reallocation during
motionHeld.
In `@src/light/drivers/DriverBase.h`:
- Line 201: Restrict the hold-state API exposed by
DriverBase::correctionForHold() so callers cannot mutate Correction or its
derived fields; add a narrowly scoped setMotionHeld(bool) or equivalent friend
API that updates only the documented hold state, and change
Drivers::updateMotionHold() to use it.
In `@src/light/drivers/Drivers.h`:
- Line 346: Synchronize publication of each driver’s motionHeld state with the
split-render frame handoff so Correction::apply() cannot concurrently read while
tick1s() writes it. Update the handoff logic around renderSplitActive_ and the
child(i) correctionForHold() assignment, preserving Correction’s existing
copy-and-rebuild contract and ensuring park/unpark transitions are not missed.
In `@src/light/moonlive/MoonLiveBuiltins_light.h`:
- Around line 886-887: Update the motion-value handling in both the pan call and
mm_light_set_tilt to use byteArg(args[1]) instead of converting through uint32_t
and manually clamping, preserving the required signed 0..255 behavior.
- Line 534: Update releaseIfEmpty to require both motion and coord sinks,
alongside the existing sinks, to be empty before clearing owner; ensure
motionSink() and coordSink() cannot use a stale context during detach
interleavings, and add a deterministic regression test covering this sequence.

Move recursive deletion off the render-task stack and detect path truncation.
HttpServerModule::tick20ms() calls handleConnection() on the ESP32 app_main task, whose configured stack is 12 KB. removeRecursive() can keep nine DirLevel objects live through depth == 8; each is about 2.6 KB, before child[192] and handleConnection()’s 2 KB buffer. A nested directory can therefore exceed the task stack and reboot the device.
On desktop, snprintf() can also truncate child because parseFilePath() accepts paths up to 159 characters and collectEntry() accepts 39-character names. Check its return value and use an iterative or heap-backed traversal, with a path buffer sized for the supported path limit. ESP32’s filesystem rejects paths above its 128-byte translated-path limit, so this path-length issue is primarily a desktop portability failure.

Preserve held motion when corrected_ is reallocated.
NetworkSendDriver::tick() and PanelCardDriver::tick() apply into corrected_. When resizeCorrected() grows it, Buffer::allocate() zero-fills the new buffer. If this occurs while motionHeld is true, apply() skips motion writes and the next frame can send zero motion. Preserve held motion across reallocation and add a regression test.

The lifecycle gates are no longer a Python runner: each event's checks are a table in CLAUDE.md, one command per check with a path trigger, run directly. Correction now takes every driver's real source width, so a moving-head preset reaches an LED driver's channels instead of being dropped. Core: ControlModule seeds a connecting surface from the target values rather than the mirror's last ones, so a surface that attaches mid-show is correct immediately. SysVarTable refuses an arena offset that a 32-bit read would run past. removeRecursive checks snprintf for truncation before deleting through a path. Light domain: applyColorOnly removed; every sink passes srcChannels and Correction's own hasMotion decides what is carried, which is the fact the pipeline already held. HueDriver's destination widened to hold a moving-head preset's channels. DriverBase exposes setMotionHeld instead of the whole Correction. setPan/setTilt read their value through byteArg, so a negative aim clamps to 0 rather than to 255. Scripts/MoonDeck: moondeck/event/ deleted (595 lines) with its MoonDeck cards; run_scenario.py gains --no-write so a check reports without dirtying the tree it just checked. Tests: the effect sweep gains 3D grids (1x60x10, 1x10x60, 8x8x8), which no case covered before, plus a test that an effect reaches past the first tube of a tube rig. Regression tests for the arena bounds and the surface seeding.

A script declares its dimensions and its tags the way the compiled module it stands in for does, so a scripted effect reads like any other in the picker and the layer extrudes it correctly. Getting there needed the language's first statement that answers rather than acts: `return`. Core: `return <expr>;` and a bare `return;`, lowered as a jump to the function's one exit so an early return still unwinds the recursion-depth counter. Every function declares what it hands back (`void`, `int`, `string`), recorded per entry point, so the host reads a value only from a function that says it has one; calling a `void` function for its value would read whatever sat in the return register. Four backends park the value in their own ABI register: x0 on arm64, rax on x86-64, a2 on Xtensa, a0 on RISC-V. Light domain: MoonLiveEffect answers dimensions() and tags() from the loaded script, read once per compile, falling back to D2 and the scripted notepad when a script stays silent. A script declaring 1 now paints a line and the framework fans it across the rig, which is what lets one script fill a 16x16 panel and a 1x60x10 tube rig without knowing either shape. UI: the script field is a button that opens the same picker the module picker uses, with its search, emoji chips and keyboard handling; a script row shows its own emoji and dimension, including for scripts not yet downloaded. Both pickers are now modals rather than blocks appended into whatever opened them, which is what put the module picker at the bottom of a card instead of beside the field. Scripts/MoonDeck: all 34 shipped scripts typed and declared (6 D1, 15 D2, 3 D3; 8 tagged). The catalog generator extracts both from the source and fails the build on a declaration it cannot read, so the two readers of the language cannot drift quietly. A development build fetches library scripts from the commit it was built from rather than main, so a script always matches the engine that will run it. Tests: the return statement per backend, with the ESP32 encodings checked by finding the ABI move in the emitted bytes; declared types accepted and refused; a script's identity reaching the module; a D1 script extruding across the width; the catalog parser, including a control that must fire. A new test compiles every script example in the docs, which found a placeholder that no user could have pasted. Docs: the language reference gains return, the return types and the dimensions()/tags() rules; the effect spec states that a grid is told to a script while its dimensionality is declared.

Each effect, layout and modifier now declares its dimension and its tags, and the picker groups its chips by what they mean. The emoji legend moved to the page end users read, because the chips are what they see on every card. Core: removeRecursive lists a directory on the heap rather than in its frame, which at depth 8 put ~20 KB on a 12 KB main task that a user could reach by nesting folders. A script's return is now checked against the type its function declared, so a value from a void function, a bare return from a typed one, and an int/string mismatch are all refused rather than reaching the host as a plausible wrong number. Light domain: HueDriver corrects in place only while its buffer provably holds the light, since presets go to 32 channels and the fixed 9-byte array was a stack overrun on the render task. Drivers re-derives motionHold's visibility on its own tick, so the control appears when a child driver selects a moving-head preset instead of waiting for a reboot. A failed script compile forgets the previous script's identity rather than pointing tags at a re-used string pool. LayoutBase declares dimensions(), and every module states its own explicitly: the default is expected to move to D3, and a stated value survives that where an implicit one silently follows it. UI: the type picker opens as a modal under the control that opened it, centered over the cards column, clamped so it stays on screen at any window height. Its chips are grouped scripted, type, dimension, origin, capability, with a separator between groups. Scripts/MoonDeck: all 34 shipped scripts declare dimensions() and tags(), carry one header line, and document each control at its addControl. check_prose.py now reads .mle/.mll/.mlm, which were unchecked: the shipped library is the most user-facing prose in the repo and had drifted to British spellings, including an identifier in the teaching script the README cites. Tests: removeRecursive gained the tests its header claimed existed (a tree, a depth refusal, a plain file); the return type checks are pinned in both directions. Docs: the emoji legend lives in the end-user page with architecture.md keeping the mechanism; the multicast discovery gap and the repo-wide spelling sweep are backlogged. Reviews: 👾 10 findings, each verified against current code. Eight fixed, one documented (a non-atomic bool whose worst case is one frame of latency), one skipped: MIGRATING.md exempts MoonLive until it launches.

changed the title
Core: removeRecursive constructs its heap DirLevel with placement new instead of re-assigning two fields the struct already defaults, so a member added later cannot be silently skipped. Its docstring named the wrong task: the walk runs on the main task, which is also the render task. Light domain: Drivers reads each driver's already-resolved correction to decide whether motionHold is shown, rather than calling fixtureChannels(), which rebuilds every driver's preset roles and its 256-entry brightness LUT. That ran once a second on the render tick, against the contract stated three lines above it. MoonLiveLayout and MoonLiveModifier answer dimensions() and tags() from the loaded script the way MoonLiveEffect does: all ten shipped layout and modifier scripts declare both, the picker showed them, and the card then forgot them. FlyingToasters and Pacman move to the frequency marker, since both drive per-sprite bands rather than reading a level. UI: the "+" tab anchors its picker to the tab. It anchored to the footer's add button, which is display:none at that depth, and a hidden element's rect is all zeros, so the modal pinned to the top of the window. Docs: the emoji comment above ROLE_EMOJI pointed at four emoji no module carries any more; it now links the legend rather than re-listing it. Four tags() glosses labelled a WLED origin marker as a dimension, teaching the one thing the vocabulary forbids. A scripted module's dimension chip still comes from its type, which needs a virtual on MoonModule to fix: backlogged with the tradeoff rather than reached for here.

A MoonLive script can now say what it is, and every module in the library says it the same way.
What a user sees
Pick a script from the library and it downloads on the spot: the device carries the catalog, the browser fetches the text from GitHub, so flash scales with how many scripts exist rather than how large they are. Every row in the picker shows what it is before you choose it, and the picker itself is now the same widget everywhere, a modal that opens under the control you clicked.
A script also carries its own dimension, so it fills the rig it is given. Declare 1 and the framework fans a line across the width; declare 2 and it copies the picture through the depth. One script works on a 16x16 panel and a 1x60x10 tube rig without knowing either shape.
The language grew a
returnScripts had no way to answer a question, only to act.
returncloses that, across all four JIT backends (arm64, x86-64, Xtensa, RISC-V), and every function now declares what it hands back:Declared types are not decoration: reading a value from a function that returns nothing reads whatever sat in the return register, which is a plausible wrong number rather than an obvious failure. The compiler now refuses that, and a mismatched
returnwith it.One vocabulary for the whole library
Every effect, layout and modifier declares its dimension and its tags, and the emoji mean the same thing everywhere: origin, creator, and the capability groups (audio, particles, motion, shader, sprites, simulation, network). The legend moved to the page end users read, since the chips are what they see on every card. The picker groups its chips by category with separators.
Dimensions are stated explicitly even where they match the default, because the default is expected to move to D3: a stated value survives that, an implicit one silently follows it.

The gate scripts are gone. Each event's checks are a table in CLAUDE.md, one command with a path trigger, run directly: the runner was orchestration around knowledge that reads better as a list.
check_prose.pynow covers.mle/.mll/.mlm, which were unchecked, and immediately found British spellings in the shipped library including an identifier in the teaching script the README cites.A development build fetches library scripts from the commit it was built from rather than
main, so a script always matches the engine that will run it.Verification
Desktop build (zero warnings), 1626 unit tests, scenarios, 100 Python, 105 JS, specs, prose, platform boundary. All three ESP32 variants build (Xtensa classic, Xtensa S3, RISC-V P4). Run on the S3 bench: scripts compile and run through the Xtensa JIT, each publishing its own controls and emoji, and the commit-pinned library fetch verified end to end.
Two Reviewer rounds; every finding verified against current code and fixed, except one skipped with reason (MIGRATING.md exempts MoonLive until it launches) and one documented (a non-atomic bool whose worst case is one frame of latency).
This PR is 225 files, past the ~100 ceiling where CodeRabbit declines to review. It reviewed the commits individually on request, and those findings are addressed.
