Every shipped MoonLive script runs on a classic ESP32, and RMT costs 3 bytes per light - #100
Merged
Conversation
Provisioning a board over USB set its WiFi and nothing else: the script sent a vendor RPC no firmware has ever handled, then reported success. It now applies the catalog entry the way the web installer does, so a fresh board comes up configured. Four device models had wrong or missing pins, including the P4 shield, where two of eight LED panels stayed dark. Performance: desktop 1199 fps, 834 us/tick; flash esp32 2057984, esp32-16mb 2058000, esp32-pico 2106464, esp32p4rev1-eth 1995280, esp32p4rev1-eth-wifi 2284640, esp32s3-n16r8 2100032, esp32s3-n8r8 2087168, esp32s31 2348592, desktop 1909464. 2000 test cases, 27 scenarios. Core: - JsonSink flags a refused heap grow instead of dropping bytes silently: a truncated document was indistinguishable from a whole one at the far end, so a board that could not allocate shipped a cut module tree under a frame header declaring it complete, and the UI lost whole cards with nothing logged. ensureHeap also steps down in quarters when a doubling is refused, which fits a fragmented heap where the doubled block does not. - The state push warns and keeps the patch stream alive when the document does not fit, rather than returning early: an early return left fullResyncPending_ set, starved the patch branch, and froze the whole UI (no fps, no heap, no live values) on a board where the state simply does not fit. Light domain: - ParallelLedDriver counts the peripheral's DMA buffers in its memory readout. They are platform-allocated and were left out on that ownership argument, which made the card lie about the figure a user picks a driver on: the i80 frame is sized by the bus width, not the pins in use, so a one-lane board reported 512 bytes against RmtLedDriver's 32 KB while costing 49 KB more free heap. Counts the buffers that EXIST, not the ones doubleBuffer asks for. UI: - Two modules whose names differ only in case shared a card. The firmware compares names with strcmp, so `lines` and `Lines` are different modules; CSS attribute selectors match case-insensitively, so every name-keyed querySelector resolved to whichever came first in the DOM and a Layer holding both rendered no effect cards at all. Narrowed in JS by queryByName(): the Selectors Level 4 `s` flag was tried first and reverted, because Chrome throws SyntaxError on it and takes out every card on the page. Scripts/MoonDeck: - improv_provision.py applies the device model as APPLY_OP ops, a faithful port of the browser's planner (clearChildren pre-pass, add, then set), sent closed-loop: each frame is acked, a busy device is retried, and the device's own state chatter is no longer read as a refusal. It probes GET_CURRENT_STATE first, so an already-provisioned board keeps its credentials and still gets the config, and an Ethernet-only entry skips the WiFi exchange entirely. - Catalog order now matters and is documented: an entry whose LED pins include GPIO 1/3 lists its driver LAST, because setting those pins ends serial reception and every later op is lost. Four entries reordered. Tests: - The Improv frame tests gained the op planner (mirroring config-ops.js case for case), the chunked framing, a scripted fake port for the closed-loop sender, and a guard that the phantom RPC never returns. - unit_JsonSink_overflow, unit_AllocTracking, ui-name-case, and the DMA readout cases in the shared host_bus harness. Docs/CI: - The MHC-WLED P4 shield reference contradicted itself: its terminal line reads O21 O20 O25 O5 O7 O23 O8 O27 while its table listed O22/O24 in positions 5 and 7. The catalog followed the table, so two strands got no signal. Table corrected, with the I2C trade-off stated (GPIO 7/8 are also the I2C bus). - Device models: Dig-2-Go gains its relay pin and GRBW preset, Dig-Octa and Dig-Next-2 move to ParallelLed with a DC pin, the P4 shield lists both its firmwares so the installer can offer the WiFi variant. - Backlog: the state-over-WebSocket architecture (snapshot over HTTP, deltas over WS), the P4 co-processor WiFi findings, the persisted firmware-variant bug, and the RMT/ParallelLed crossover measured at ~500 lights. - The WebSocket streaming plan is archived as attempted-and-reverted: it worked on the bench and still crashed a 65 KB board on a UI refresh, because the chain holds the whole document for the drain's duration.

In `@docs/backlog/backlog-light.md`:
- Line 884: Update the memory formula near the ParallelLedDriver discussion to
express usage as lights × channels × 8 × 4 bytes per light, explicitly
identifying 96 bytes per light as RGB-only and noting that configurable
channelsPerLight makes RGBW/GRBW 128 bytes per light; adjust the downstream
crossover and memory guidance accordingly.
In `@docs/reference/mhc-wled-esp32-p4-shield.md`:
- Line 25: The documentation’s default Parallel LED lane description is
inconsistent with the physical mapping. Update the default configuration text
near the Parallel LED guidance to identify GPIO 7 and GPIO 8, and explicitly
instruct users to reconfigure the Parallel LED lane pins before moving those
strands to O22 and O24 for I²C use.
In `@moonbase/main/moonbase_main.cpp`:
- Line 489: Update the chip-to-asset-prefix rule in fwList() to recognize
ESP32-P4 asset names using the esp32p4rev family, including names such as
esp32p4rev1-eth. Preserve the existing exact VAR-based filtering behavior when
VAR is available.
In `@src/core/HttpServerModule.cpp`:
- Around line 2980-2989: Update pushStateToWebSockets around sink.overflowed()
so an overflowed truncated frame is never passed through baselineLeafHashes() or
used to clear fullResyncPending_. Add a recovery path that produces and sends a
complete state frame before establishing the leaf baseline and clearing the
resync flag; otherwise retain the pending resync state for a later complete
frame.
In `@src/core/SystemModule.h`:
- Line 173: After the final FilesystemModule::reapplyValues() restoration pass,
overwrite the persisted firmware variant with kFirmwareName, then call
markDirty() and FilesystemModule::noteDirty() so the corrected value is saved;
keep the existing firmwareVariant_ initialization in SystemModule::setup()
unchanged.
In `@src/light/drivers/ParallelLedDriver.h`:
- Around line 1397-1409: Update driverHeapBytes() to use an aggregate DMA
allocation size exposed by MoonI80Peripheral, including all ringBufs slices and
any shared zero-pad buffer, while preserving existing non-ring accounting. Add a
ring-mode accounting test that verifies the reported heap usage includes the
full createRingState() allocation.
In `@src/platform/esp32/platform_esp32.cpp`:
- Around line 225-233: Update the ESP32 allocation wrappers alloc(),
allocInternal(), and free() to track only their own allocations using size
metadata, maintaining allocated bytes, peak bytes, and live-block counters.
Replace the MALLOC_CAP_8BIT-based implementations of allocated() and
allocatedPeak() with these wrapper-maintained metrics, preserving correct
bookkeeping across successful allocations and frees.
In `@src/ui/app.js`:
- Line 2815: Fix the filepath branch in createControl by removing the undefined
v argument and calling buildFilePathControl with only the values it uses; update
buildFilePathControl’s signature to remove its unused v parameter while
preserving its ctrl.value-based behavior.
- Line 4524: Update the queryByName call in the loop to pass the raw module name

data-mid comparison aligned with the raw value so live control patches continue
to match module IDs containing quotes or backslashes.
In `@test/python/test_improv_frame.py`:

Do not baseline an overflowed full-state frame.
ws.onmessage passes the complete text to JSON.parse; truncated JSON throws, and the catch ignores the entire frame. It does not apply a partial tree. However, pushStateToWebSockets() still calls baselineLeafHashes() and clears fullResyncPending_ after accepting that frame. Later patches omit unchanged leaves from the baseline, so a new or structurally changed client can remain incomplete. Only baseline and clear the resync flag after producing a complete frame. Add an overflow recovery path that can produce such a frame.

Persist the compiled variant after the final restore pass.
FilesystemModule::reapplyValues() runs after SystemModule::setup() and can overlay the old persistable "firmware" value again. MoonBase reads this value from SystemModule.json and can filter assets for the previous variant after an OTA. Add a post-restoration step that writes kFirmwareName, calls markDirty(), and calls FilesystemModule::noteDirty().

Optionally record retry payloads.
send_apply_op builds each bytes frame once and reuses the same frame after each busy response. The current implementation cannot resend different bytes on this path. If this invariant should be pinned, record data in FakePort.write and assert that all retry entries equal the first. No checked-in CI or lint configuration enforces an unused-argument failure.

Make the overflow case deterministic.
mm_tests runs this case in CI, but heap-mode JsonSink uses the host allocator. On hosts with enough memory, the loop can allocate about 256 MiB and take the else branch without testing overflowed(). On lower-memory hosts, allocation can fail at a different point or terminate the process before the flag is set. Add a test-only allocation-failure seam or bounded allocator fixture so the overflow assertions run without host-dependent memory growth.

The RMT LED driver no longer pre-expands every data bit into a 32-bit hardware symbol. It ships the corrected wire bytes and the peripheral does the expansion, which cuts its memory from 96 bytes per RGB light to 3 and removes the ceiling where a long strand silently stopped updating. A Dig-2-Go handed 33 KB of internal RAM back to the system; a Dig-Next-2 now drives 2048 lights flicker-free where 900 used to freeze the strip with a healthy-looking status. Performance: flash +816 B esp32, +1424 B esp32s3-n16r8, +624 B esp32p4rev1-eth, +208 B desktop. Driver heap at 1024 lights: 98,307 B to 3,075 B. Scenario ticks unchanged or slightly better across the matrix. **Core** - MoonBase's firmware picker recognizes the P4's `esp32p4rev1-*` assets. The chip/hyphen boundary rejected every one, so a P4 in recovery saw an empty list, which is the one place a user has no other way to install. **Light domain** - `RmtLedDriver` keeps a wire-byte frame (`lights x channels`) instead of a symbol buffer (`lights x channels x 8 x 4`). Expansion moves to the IDF bytes encoder on the DMA chips and to the level-5 refill on classic ESP32. - Above what internal RAM could give, the old buffer fell back to PSRAM, which the classic refill cannot read with the flash cache off, so `rmtWs2812Transmit` refused every frame while the card reported "driving N of N". That path now reports the failure and releases the buffer rather than freezing quietly. - `platform.h` gains `rmtWs2812SetBitTiming`; `rmtWs2812Transmit` takes bytes. The pre-expanded symbol API and `encodeWs2812Symbols` are gone. **UI** - The module-name comparison in the live control patch used the CSS-escaped name against the raw `data-mid` attribute, so a name needing escaping stopped matching and its card silently stopped updating. - `buildFilePathControl` no longer takes an argument that was never defined at the call site nor read in the body. **Scripts/MoonDeck** - `ioreg` output is decoded leniently. A `UnicodeDecodeError` is neither `OSError` nor `SubprocessError`, so a non-UTF-8 byte escaped the handler and 500'd every `/api/ports` request, emptying the port dropdown with boards attached. - The web installer's progress bar crosses once per install rather than once per image, and the post-flash port reopen waits for a fresh user gesture. **Tests** - Pin-offset expectations move from symbol words to bytes. They previously pinned the wrong contract and would have kept the multi-pin bug green. - The encoder tests keep the MSB-first and channel-order contracts against a reference expander, since the real expansion now happens in hardware. - New: the installer's flash-progress function (6 cases). **Docs/CI** - New tutorial: running projectMM on a Linux machine, covering x86-64 packages and building from source on an arm64 SBC (Raspberry Pi, NanoPi R28S). - The P4 shield's LED-lane default said GPIO 22/24 where the catalog uses 7/8, and the I2C workaround now says the driver's `pins` must change too. - Backlog: an arm64 Linux release build, a flashable SD image, and the ring driver's heap readout counting one buffer rather than the pool. **Reviews** - 👾 Reviewer: `pinOffsets_` stayed in symbol words while `tick()` read them as bytes, so every pin after the first was 8x off and never transmitted. Fixed, and verified on a Dig-2-Go: adding a second pin took 51 to 101 fps. - 👾 `symbolsUnusable_` promised a PSRAM check it did not do -> done. Dead `ensureWire` scratch -> removed. Split `symbols_`/`frame_` vocabulary -> unified. Half-block multiple-of-8 assumption -> `static_assert`. Stale symbol-era comments in four files -> rewritten. - 👾 Two false claims in the new tutorial: a container image that ships only in an unmerged PR, and a byte figure contradicting its own formula -> corrected. - 🐇 CodeRabbit: filepath `v`, `queryByName` escaping, the P4 asset prefix, the 96-bytes-per-light formula, and the P4 shield I2C guidance -> all fixed. WebSocket overflow finding -> skipped: it asks for the behavior we reverted this session, where retaining the resync flag starves the patch branch and freezes the whole UI. Persisted-firmware and ring-accounting findings -> backlogged, both needing design decisions beyond a minimal fix. Test-determinism findings -> not addressed, they need new test seams.

The compiler was never the problem: three heap allocations made at once exceeded the chip's largest free block, and each failure was reported as "codegen failed". Two of 33 shipped scripts ran on a Dig-Octa before; all 33 run now, on the Octa and on a Shelly, each swept end to end with no reset and every script transmitting. The RMT driver also stops sleeping a scheduler tick per frame (Shelly 100 to 957 fps, Octa 100 to 358), classic boards move to RMT by default, and a Linux/SBC install tutorial lands. Performance: flash +1472 B esp32, +2144 B esp32-16mb, +1344 B S3, +1440 B P4, +528 B desktop, for the refusal diagnostics and the maxExec probe. Compile transient heap on classic: ~110 KB peak to ~40 KB for the largest script. worst_ccn 108 to 128: spillToBudget grew the dry-pass count and fast path. **Core** - MoonLive lowering emits into the caller's staging buffer; the assemblers gained a borrowing constructor, so the full-size twin buffer and its memcpy are gone. - kIrOpsPerToken 4 to 1: measured 0.75 ops per token across every shipped script, never above 0.85. The old bound reserved 61 KB for 10 KB of IR. - spillToBudget skips its rewrite when nothing spills (32 of 33 scripts) and otherwise sizes the rewrite array by an exact dry pass, not 6x worst case. - The four ways a lowering can refuse now carry distinct messages, and the allocator records which guard fired with the budget it saw. That is what found the cause: the device named "guard 11", an allocation, for scripts the host lowered without complaint. thread_local: the suite compiles from two threads and CI runs TSan. - maxExecAllocBlock() on the platform and `maxExec` on /api/system, so the executable pool is reported rather than inferred (on classic it equals maxBlock: one pool). - /api/ports survives a non-UTF-8 byte in `ioreg` output. **Light domain** - rmtWs2812Wait spins to about one scheduler tick before vTaskDelay(1). The yield slept 10 ms whatever the frame took, so 8 lights cost the same as 256; the tick now tracks the wire. - rmtWs2812SetBitTiming commits the bit shapes only on success and the transmit refuses until they are set, so no frame can clock zero symbols. nsToTicks converts at the channel's own granted resolution. - Dig-Next-2 and Dig-Octa move to RmtLedDriver (every other classic board already was); the Octa pins flashBaud 460800, which is what its bridge sustains. **UI** - The filepath picker's live update matched a `select` that no longer exists; it is a button, so a script changed elsewhere never repainted. **Tests** - The Xtensa codegen test compiles every shipped script from disk at the device's own code budget, asserting the on-disk count. A compiler guardrail: a host has no heap ceiling. - Pin-offset expectations move to bytes; a missing code buffer is refused before lowering. **Docs/CI** - Tutorial: running projectMM on a Linux machine, x86-64 package or arm64 build from source (Raspberry Pi, NanoPi R28S), Debian-family throughout. - esp-idf#19025: Espressif found the P4 hardware-loop root cause (misaligned esp-dsp loops, a mis-gated erratum guard). The sdkconfig note and backlog cite it; the save-path guess is recorded as wrong. - Backlog: completed entries removed; the classic-memory entry now names where the RAM is (WiFi, lwIP, task stacks; modules hold under 10 KB). **Reviews** - Reviewer: my backlog edit deleted five open Distribution entries by replacing a range; restored byte for byte, then the completed entries removed on purpose. The three diagnostic statics raced under the suite's two-thread compiles; thread_local, and the spill message moved into the CompileResult so a second failing module cannot rewrite the first's status. kNoCodeMemory was unreachable: deleted with its mapping and the test that pinned only a string. The reserve comment claimed "cannot undershoot" while the design undershoots by measurement: rewritten. 33 scripts duplicated as literals: the test reads the real files. Stale buf_ comments and the moxygen field list: fixed. - CodeRabbit: swap advice needed `dphys-swapfile setup`; per-channel RMT resolution; transmit gated on timing; filepath selector. All fixed. Peak CAS loop skipped: the code declares that race accepted, and a CAS on the allocator hot path buys a diagnostic. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>

Do not busy-wait on the render path.
RmtLedDriver::tick() calls rmtWs2812Wait() after transmit. Line 392 occupies the render task for up to 10 ms before it can yield. A 256-light WS2812 lane needs about 7.68 ms on the wire, so this blocks normal render cycles. Longer frames then block through vTaskDelay(1).
Use asynchronous completion with frame ownership or double buffering. Return pending status to the render loop instead of spinning or sleeping here.

Two pre-merge review findings. The allocator's refusal message had been moved into the CompileResult to stop a shared static racing, which turned the race into a pointer at a dead stack frame: a script the register allocator refuses showed stack garbage as its status. And a board flashed from one variant to another kept reporting the old firmware name, which is the field MoonBase's recovery list keys on. Performance: flash +224 B esp32-16mb, +224 B S3, +96 B P4, +256 B desktop, the refusal detail line and the firmware re-assert. complexity.over_threshold +1 (SystemModule::onControlChanged gained a branch). **Core** - The register refusal is a string literal; the numbers behind it live in the thread_local spillDetail and MoonLive formats them into ONE file-static line on that cold path only. Nothing added to the engine or the result: the per-instance buffer a first fix proposed was rejected for exactly that cost. The line is sized to the worst case GCC's -Wformat-truncation proved (six three-digit fields), which clang had not flagged. - SystemModule re-asserts kFirmwareName whenever the persisted `firmware` text is written back, and marks dirty so the correction persists. - kNoCodeMemory deleted: compileSource refuses a missing buffer before any lowering runs, so the mapping was unreachable. **Light domain** - RmtLedDriver's remaining symbol-era comments say wire bytes, and the timing comment now matches the code: a `timing` change reaches the peripheral via reinit() and pushBitTiming, not a per-frame read. **Docs/CI** - performance.md no longer says RMT bails with no status or reports 0 bytes; backlog-light's inverted PSRAM claim corrected, the shipped alloc-status item deleted, and the frameUnusable_ test backlogged with the seam it needs (the desktop allocator never refuses, so a test against it passes vacuously). - Stale SET_DEVICE_MODEL references removed: the firmware has two vendor RPCs, not three. An orphaned moonbase comment removed. **Tests** - Pins the register refusal returning a literal with spillDetail recorded, and a stale persisted firmware name being overwritten on write. **Reviews** - Reviewer + CodeRabbit, the same bug from both: the spillMsg use-after-scope. Fixed as above. Reviewer: firmware re-assert, symbol-era comments, the two inverted doc claims, the shipped backlog item, the orphan comment, the RPC refs: all fixed. The frameUnusable_ guardrail: backlogged, no seam exists. - CodeRabbit: peak CAS skipped (the code declares the race accepted; a CAS on the allocator hot path buys a diagnostic); async RMT double-buffering skipped (a driver redesign, not a fix: the wait was blocking before this branch and the change only shortened it); app.js cssEscape finding wrong, `k` is already escaped at its definition.

All three sanitizer lanes failed at COMPILE, before running a test: the firmware-name regression test used std::string without <string>. Clang resolves it transitively and GCC does not, which is the class the --gcc build exists to catch; it reproduced the failure locally and links clean with the include. No behavior change. **Tests** - unit_SystemModule.cpp includes <string>. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
Both sanitizer lanes failed on one assertion: the register-refusal test compared `r.error == kSpillRefused` by pointer. Clang merges identical literals so the addresses coincided locally; GCC gives the inline constexpr a distinct address per translation unit and the compare failed on CI while the strings were identical. The contract is the text, so it is a strcmp. Proved on the GCC build, which reproduced the failure: 1904 pass on both toolchains. **Tests** - unit_moonlive_compiler.cpp: strcmp, with the reason recorded.

Every shipped MoonLive script now runs on a classic ESP32, the RMT LED driver costs 3 bytes per light instead of 96 and no longer sleeps a scheduler tick per frame, and a board provisioned over USB comes up configured. Four commits, verified on seven bench boards.

What changed
MoonLive on classic ESP32. The compiler was never wrong: three heap allocations made at once exceeded the chip's largest free block, each reported as "codegen failed". The assemblers borrow the caller's staging buffer instead of allocating a full-size twin (0 instead of 16 KB); the IR array is sized to the measured 0.75 ops per token instead of a guessed 4 (12 KB instead of 61); the spill pass skips its rewrite when nothing spills, 32 of 33 scripts (0 instead of 41 KB). Codegen goldens are byte-identical on all three ISAs. The four ways a lowering can refuse now carry distinct messages and the allocator records which guard fired, which is what found the cause. A test compiles every shipped script from disk at the device's own budget.
RMT driver. Wire bytes instead of pre-expanded 32-bit symbols; the peripheral expands bits (IDF bytes encoder on DMA chips, an inline level-5 refill on classic). A pre-merge review caught that
pinOffsets_stayed in symbol words, which would have broken every multi-pin board; fixed and verified on 8 lanes.rmtWs2812Waitspins to about one scheduler tick beforevTaskDelay(1), which slept 10 ms whatever the frame took: 8 lights cost the same as 256. Bit timing commits only on success and a transmit refuses until it is set. Two classic boards move to RmtLedDriver by default; the Dig-Octa pins the flash baud its bridge sustains.Provisioning.
improv_provision.pyapplies the catalog entry as closed-loopAPPLY_OPframes, the way the browser does; it had sent a vendor RPC no firmware handles and reported success. Catalog rule from the bench: an entry with GPIO 1/3 (UART0) as LED pins lists its driver last.Core.
JsonSinkflags a refused heap grow instead of truncating silently, and the state push warns and keeps the patch stream alive rather than freezing the UI.maxExecon/api/system./api/portssurvives a non-UTF-8 byte inioreg.SystemModulere-asserts the compile-time firmware name over a stale persisted one (the field MoonBase keys on).UI / installer. Case-colliding module names got one card; fixed with
queryByName(). The web installer's progress bar crosses once per install rather than once per image, and the post-flash port reopen waits for a user gesture. The filepath picker's live update matched aselectthat is now a button.Docs. A tutorial for running projectMM on a Linux machine (x86-64 package, or arm64 build from source on a Raspberry Pi or NanoPi R28S, Debian-family throughout). The P4 shield reference corrected against its own terminal line. esp-idf#19025: Espressif found the P4 hardware-loop root cause (misaligned esp-dsp loops, a mis-gated erratum guard); our notes cite it and record the save-path guess as wrong.
Attempted and reverted
WebSocket state streaming (worked on the bench, crashed a 65 KB board on refresh), the P4 co-processor WiFi gate and retry (refused WiFi on a healthy board), and a chatter/log-level theory for CH340 sync failures (disproved: the tick line does not block a sync). All backlogged with evidence.
Performance
Flash: esp32 2060272, esp32-16mb 2060368, esp32-pico 2107168, esp32p4rev1-eth 1997440, esp32s3-n16r8 2103024, desktop 1910456. 1904 unit test cases, 24 scenarios, 136 JS, 170 Python. Compile transient heap on classic: ~110 KB peak to ~40 KB for the largest script.
