A spare i80 bus lane was parked on a real GPIO, and on the S31 that pin is an Ethernet transmit line: every frame the MAC sent went out corrupt while the link reported 1000 Mbit with zero drops. Fixing it made both the LED panel and S31 Ethernet work for the first time. The pin map now shows the pads a peripheral holds without a control naming them. Performance: no tick-path change; the added work is one virtual call on the bus build path, never per frame or per light. Light domain - LedPeripheral::spareLanesNeedPad() (default true, false on MoonI80): esp_lcd rejects an NC data pin so it must park spares on a real pad, but a backend that routes its own GPIOs leaves them unconnected. busPinCount() now hands such a backend only the lanes a strand reads, so a one-strand board stops driving six or seven GPIOs it never asked for. Core - MoonModule::fixedPins(): the GPIOs a module holds that are NOT controls, which is how a silicon-fixed pad reaches the pin map. Reported only while the module uses them, so a board with ethType None spends those pins on LEDs; three of the four classic boards in the catalog have no PHY at all. - PinsModule asks every module for them. The map reads controls as the pin registry, and a pad no control names is a pad it shows free while a peripheral drives it. - NetworkModule reports the twelve RGMII pads from one platform::ethRgmiiPads list that ethInitEmac also reads, by name rather than by index so a reorder cannot rewire the MAC. They are not controls: nobody can choose them. - MDC/MDIO are shown on RGMII, not only RMII. ethInitEmac sets smi_gpio outside the interface branch, so an RGMII board drives them too; hidden, they were two more pins the map could not see. - The classic ESP32's default states MDC 23 / MDIO 18 rather than -1. The MAC used those either way (a -1 makes ethInitEmac skip smi_gpio and IDF applies the same pair), but -1 is invisible to the map. NOTE: a board with -1 already persisted keeps it; set them once or erase NVS. - The Ethernet status carries the negotiated link speed, so a gigabit PHY that fell back to 100M is visible rather than looking identical. Scripts/MoonDeck - grid.mll: cols/rows reach 128, so a scripted grid can fill 16384 lights. Tests - a peripheral that routes its own pins is handed only the lanes it drives. - the RGMII pad list's count matches its length (a static_assert where it is evaluated: hasEthernet is false on the desktop, so a host test of the control side would assert nothing). Docs/CI - docs/friend-repos/ holds the friend-repo digests, moved out of history/ with the digest prompt that generates them; a new Funkelfetisch/projectMM digest covers the fork building HELIO on this project. - backlog: the GPIO collision, the RMII data pins and the classic MDC/MDIO gap that remain open, and the S31 Ethernet entry DELETED: it blamed an RGMII Tx-clock mismatch since 2026-07-26, and the cause was this same pin. Reviews - 👾 Reviewer (Fable) over the staged diff, 8 findings. Fixed: a zero-size constexpr array that MSVC rejects (the Windows CI job compiles that header), a test that asserted nothing on the desktop, a positional pad-to-role mapping in two places, the digest-prompt links, four link labels, a stray blank line. Investigated and dropped: a scenario tick bound loosened 103 to 242 us, which re-measured clean on an idle machine, so the tighter bound stands. Left for the PO: `readonly` is a UI hint rather than a write gate, which is a core-wide question rather than part of this change. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

| Monthly logs of what shipped on related open-source LED projects — the live landscape projectMM watches to sharpen its own designs under the *Industry standards, our own code* principle ([CLAUDE.md § Principles](../../CLAUDE.md#principles)): study to think, write fresh, never copy. Generated by the [digest prompt](#digest-prompt-reusable) below. | ||
|
|
||
| - [FastLED-FastLED.md](FastLED-FastLED.md) — the LED-animation library; ESP32/Arduino driver + color math. | ||
| - [wled-WLED.md](wled-WLED.md) — upstream WLED firmware. | ||
| - [MoonModules-WLED-MM.md](MoonModules-WLED-MM.md) — MoonModules' WLED fork (the direct lineage). | ||
| - [troyhacks-WLED.md](troyhacks-WLED.md) — troyhacks' personal fork of WLED-MM (PixelForge, RMTHI, audio-reactive hardening). | ||
| - [Funkelfetisch-projectMM.md](Funkelfetisch-projectMM.md) — a fork of THIS project building a commercial product on it (HELIO, a physical infinity-sphere lamp); the work lives in feature branches, not on its default branch. | ||
| - [PlummersSoftwareLLC-NightDriverStrip.md](PlummersSoftwareLLC-NightDriverStrip.md) — Dave Plummer's LED matrix/strip firmware. | ||
| - [hpwit-I2SClocklessLedDriver.md](hpwit-I2SClocklessLedDriver.md) — hpwit's I2S/LCD DMA clockless LED driver (parallel multi-strip output). | ||
| - [hpwit-I2SClocklessVirtualLedDriver.md](hpwit-I2SClocklessVirtualLedDriver.md) — the shift-register "virtual pins" variant of the above (dormant since 2024). | ||
| - [hpwit-ESPLiveScript.md](hpwit-ESPLiveScript.md) — hpwit's live C-like script compiler for the ESP32 (main quiet; work moved to version branches). | ||
| - [hpwit-new-parser.md](hpwit-new-parser.md) — **ESPLiveScript2**, hpwit's from-scratch rewrite of the above (repo is named `new-parser`; the library lives in `asmparser2/`). Dormant May 2025 → August 2026, then an active rewrite whose stated goal is a *verifiable* compiler: host builds plus QEMU running the actual compiled Xtensa bytes. | ||
|
|
||
| ## Digest prompt (reusable) | ||
|
|
||
| > **Friend-repo monthly digest.** For the repo `<NAME>` (local clone at `<PATH>`, or via `gh api repos/<owner>/<NAME>`), summarise what landed on its **main/default branch** during `<MONTH YEAR>`. | ||
| > | ||
| > 1. Read the merged commits on the default branch with author-date in that calendar month (`git log --first-parent --since/--until` on the local clone, or the GitHub API). Use `--first-parent` so it's the merged-feature view, not every squashed sub-commit. The default branch isn't always `main`/`master` — check (`git remote show origin`); e.g. WLED-MM's is `mdev`. | ||
| > 1b. **Also investigate the issues over that month.** The REST `gh api repos/<owner>/<NAME>/issues` endpoint returns **pull requests too** — filter them out (`--jq '.[] | select(.pull_request == null)'`) or use the GitHub **search** API, which already excludes them: `search/issues?q=repo:<owner>/<NAME>+is:issue+created:<YYYY-MM-DD..YYYY-MM-DD>` (and the same with `closed:`). Only real issues, not PRs. The commit log shows what shipped; the issues show what users *hit* and what the maintainers are prioritising — the two together are the real activity picture. Skim: notable bugs opened (recurring pain points, hardware quirks), fixes closed that map to a commit, and any heavily-discussed feature request or design thread. Fold the user-facing ones into the summary below (a widely-reported bug that got fixed, a feature the community is pushing for); an issue with no user-facing outcome yet is still worth a one-line "watching:" note if it signals a direction. Don't list every issue — surface the few that matter, the same bar as the commit summary. | ||
| > 2. **Split a month at any release boundary — but only if the release was cut from the branch you're summarising.** If a *versioned* release was published mid-month (check `git for-each-ref refs/tags` / the GitHub releases API; ignore rolling tags like `nightly` and prereleases), AND the tag is an ancestor of the digest branch (`git merge-base --is-ancestor <tag> <branch>`), split that month at the release date into `## <Month Year> (up to v<X>)` / `## <Month Year> (post-v<X>)`. If the tag is NOT an ancestor (the project cuts releases from a separate release branch — e.g. upstream WLED tags off `0_15`/release branches, not `main`), do NOT split: keep the month whole and just note which release shipped that month as context, since the trunk you're summarising feeds future releases rather than being the release line. Whole months with no in-branch release stay one section. | ||
| > 3. Write an **end-user-readable** summary: what changed that a *user of the library* would notice or care about — new features, new hardware/platform support, notable fixes, breaking changes. Skip internal refactors, CI, test-only, and dependency bumps unless they affect users. | ||
| > 4. Format as **short bullet points**, each one line, plainest language, minimal jargon. Group only if there's a natural split (e.g. "New" / "Fixed"); otherwise a flat list. | ||
| > 5. Add it as a `## <MONTH YEAR>` section to `docs/friend-repos/<NAME>.md`, newest month on top. Don't editorialise or compare to projectMM — just report what they shipped. |

A MoonLive script's controls came back at their defaults however they were set: a scripted grid layout always booted 16x16. The values were saved correctly all along, and thrown away on load. Also reports the P4's Ethernet data pins in the pin map, and re-measures the WiFi co-processor's HTTP cost. Performance: no tick-path change; the new load pass runs once, during setup. Core - Scheduler gains a phase 5: after every module has prepared, saved VALUES are re-applied once. Boot order is defineControls, load, applyState, and a MoonLive script's declared controls exist only after the script COMPILES, which is prepare()'s work. So at load time `cols`/`rows` were in no control list at all, overlayControls skipped them, and prepare() then seeded them from the script's own defaults. applyNode already had a two-pass overlay for a schema depending on a control VALUE (ParallelLedDriver's `peripheral`); this covers a schema depending on prepare's WORK, which no rebuildControls() can produce. - FilesystemModule::reapplyValues re-reads and overlays values only, no tree reconciliation: the shape was settled by the load pass. Once, at boot: after that the live values are the truth and re-reading would undo the edit that triggered any later prepare. It re-reads rather than holding every node's JSON until prepare, which would cost memory on every module for a case that is three (the effect, layout and modifier bindings, and a future driver script). - NetworkModule reports the P4's six RMII data pins through fixedPins(), the same path the S31's twelve RGMII pads use. Verified on MM-P4: Network owns all ten of its Ethernet GPIOs, against four before. platform::ethRgmiiPads is renamed ethFixedPads, since it now holds RMII pins too and the old name was a lie. Tests - a control that only exists after prepare() keeps its saved value (fails without the phase, 16 vs 42). - the pin map lists the pins a module holds without a control naming them, frees them when it stops, and states a capacity the module must respect. Docs - performance.md: the P4's WiFi co-processor costs ~4x per HTTP request and ~2x throughput against the same board on Ethernet, measured on both images over the same cable. No scenario captures this, which is what this page is for. - backlog: the co-processor penalty re-measured on v6.1-rc1 (4x/2x, against 33-60x/17x when written, and the alternating 0.4/0.8 s pattern gone); the classic MDC/MDIO gap marked fixed; the scripted-control entry deleted rather than deferred. Reviews - 🐇 CodeRabbit, 13 findings, each verified against current code. Fixed: the classic MDC/MDIO entry still claiming -1, two comments describing the control approach that fixedPins() replaced, a self-contradicting release-boundary note, and unbounded issue queries in the digest this branch added. Skipped with reason: a prose sweep over the friend-repo digests, which check_prose exempts because they quote other projects' own summaries and rewriting them falsifies the record; two "typos" that are quoted upstream text; and retro-fitting audit queries onto eight historical digests, which would fabricate an audit trail. The one finding with real substance was that fixedPins() had no test at all. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

Rebuild value-dependent late schemas before the final overlay.
reapplyNode restores only the controls that exist at entry. If a restored late control changes its module's control schema, controls selected by that value do not exist yet and keep their defaults. This differs from applyNode, which performs overlay, rebuildControls(), then overlay again.
Keep this pass value-only, but use the same two-overlay sequence before visiting children.
Proposed fix
void FilesystemModule::reapplyNode(MoonModule* m, const char* json, const char* prefix) {
if (!m) return;
overlayControls(m, json, prefix);
+ m->rebuildControls();

Rebuild derived state after value restoration.
Phase 4 builds derived state before this hook runs. reapplyValuesHook_ then changes bound values without calling prepareTree(). A late control that affects dimensions, mappings, or peripheral allocation leaves the prepared state based on its script default.
Run prepareTree() after a successful value-only pass. Extend the regression test to assert state derived from the late value, not only the backing member.

Source: Coding guidelines
MoonLive scripts can divide, draw soft-edged shapes that melt into each
other, and leave decaying trails. Every trail in the system now fades at
the rate the effect asked for rather than at whatever speed the hardware
renders, so a tail is the same length on a 470 fps board and a 140,000 fps
desktop.
Performance: desktop 1,167 KB (+1), esp32 1,715 KB (+0), esp32s3-n16r8
1,756 KB (+2). metal.mle 59.6 ms/frame on shiffy's 80x48 (12,288 host
calls per frame, 3 square roots per pixel); plasma.mle 16.0 ms as the
reference.
Core:
- '/' and '%' are operators, at multiplication's precedence. Both lower to
the host call `mod` already used, so the operator costs nothing the
capability did not: no ISA here has a divide. The parser resolves them by
NAME through the builtin table, so core stays domain-neutral and a domain
registering neither simply has no operator.
- Layer::fadeToBlackBy takes a RATE per reference frame; the Layer scales it
by elapsed time and carries the sub-unit remainder. The clock advances on
every frame, not only on frames that fade: leaving it frozen let a gap
discharge as one full wipe, snapping a trail to black on resume.
Layer::prepare resets it, the guarantee LissajousEffect used to give for
its own trail, now given once for every effect.
- Classic ESP32 RMII pins declared (TX_EN 21, TXD0 19, TXD1 22, CRS_DV 27,
RXD0 25, RXD1 26), from IDF's own RMII Data Plane GPIO table. All ten
Ethernet pins now appear in the pin map; verified on MM-Olimex at 100 Mbit.
Light domain:
- Five builtins: smoothstep, uvX, uvY, smin, fade. Each folds several host
calls into one on the per-pixel path, which is the bar now that '/' covers
the general case. uv computes one axis per call rather than discarding half
of a two-axis result, and stays 32-bit so a large width saturates instead
of wrapping past its own guard.
- signedArg() is one helper rather than six copies: a script's arithmetic is
unsigned, and a builtin that forgets to re-center renders INVERTED rather
than failing.
- Three effects hand-rolled the elapsed-to-amount conversion and had drifted
into two versions (one carried the fraction, two floored to 1 and so
over-faded at high rates). All three deleted; the Layer owns it.
- RandomEffect spawns per second, StarField's fade left the step gate that
throttled it twice, SphereMove clears with draw::fill. fadeToBlackBy(255)
no longer means CLEAR: a second meaning at the top of six user-facing
sliders was a discontinuity in kind, not degree.
- BlurzEffect is NOT migrated and stays framerate-dependent at 3.57. Its
per-frame draw::blur is a COMPOUNDING spatial operation, so the carry
pattern does not transfer; fixing it needs draw::blur itself to become
time-aware. Recorded in the test with its reason.
Scripts/MoonDeck:
- moonlive/effects/metal.mle: three blobs of liquid metal melting together.
The blend control at 0 is three overlapping circles; raised, one surface.
Tests:
- Framerate bands recorded per effect with reasons rather than widened for
all 51. Random and StarField sit outside the lit-pixel metric while their
physics matches within 0.5% across 60/240/1200 fps.
- Four goldens re-blessed (Fireworks, Lissajous, StarField, BouncingBalls).
SphereMove's did NOT move, which is the check that draw::fill reproduces
what the sentinel did.
- A test that could not distinguish fixed from broken was removed rather
than kept: a control check showed it passed with the bug reintroduced.
Docs/CI:
- The tick-rate rule extended to modifiers and to anything on the tick path,
plus where the machinery lives and the two traps found by hitting them.
- coding-standards gains the practical form: the carry pattern, why flooring
to 1 is the bug, and checking whether something upstream already scales.
- Roadmap item 9 (division) marked shipped; 9b added for the ScratchBuffer
pool handle that particles need.
Reviews:
- 👾 Reviewer over the staged diff, 10 findings.
- Fade clock frozen on non-fading frames -> fixed (a 5 s gap became a full
wipe: scale 2048, rate 60 became amt 480 clamped to 255).
- Layer::prepare missing the clock reset -> fixed, orphaned comment removed.
- fadeToBlackBy(255) sentinel -> removed entirely, SphereMove uses fill.
- uvX/uvY double divides + defeated narrowing guard -> both fixed.
- signedArg duplicated six times -> extracted.
- Two tests not earning their place -> one deleted, one now asserts the
overflow case its description promised.
- div lacking the unsigned warning its siblings carry -> accepted, noted.
- Framerate bands without a backlog entry for Blurz -> accepted; recorded
in the test rather than filed, since the fix is named there.
- Dead code after the deletions -> removed.
- releaseIfEmpty checking the new sink -> verified correct, no change.

Review findings for

MoonLive scripts can now drive the particle kernel: a script sizes its own pool and calls whole-pool physics, so a 300-spark fountain costs less than a shader that touches every pixel. Four example effects ship with it. Separately, a filesystem scan that ran every second on the render thread now runs once a minute, which removed a visible stutter on every device. Performance: desktop 1,185 KB (+18), esp32 1,715 KB (+0), esp32s3-n16r8 1,759 KB (+3). On shiffy's 80x48: fountain.mle 1,093 us against metal.mle's 59,600 us, the per-frame cost model against the per-pixel one. The filesystem fix moved frame deltas from 83/78/80/79/82/66/72 to 83/85/85/83/84/87/85. Core: - FileManagerModule::tick1s called platform::filesystemUsed() every second, which is esp_littlefs_info walking every block of the partition (~80 ms on an S3), INLINE on the render thread, to feed one progress bar. Throttled to once a minute. Pre-existing on main; particles are what made it visible, because a particle integrates a stall into its trajectory (one frame after an 80 ms gap moves every particle 6.7x its usual distance) where a shader just redraws from the clock and skips a frame invisibly. Light domain: - MoonLiveParticles holds six ScratchBuffers, a Pool and a FrameTime, owned by the effect binding. Particle state lives OUTSIDE the script arena: a Pool is eight parallel arrays, and at 64 bytes a script could hold about five particles. Widening the arena was the wrong fix, since sizeof(MoonLive) is probed on the main task's stack by registerType. - Nine builtins: pool, emit, gravity, drag, step, age, render, bounce, collide. pool(n) is reachable ONLY from defineControls(): called from tick() it reports the live count and allocates nothing, which is what keeps a malloc off the render path. The frame scale rides on the pool handle, so framerate independence is the system's property rather than the author's. - collide was rejected in the plan as an O(n^2) foot-gun and re-admitted on measurement: 3.2 us at 48 particles against 0.1 us without, 53.6 us at 200. The quadratic is real; at ball-pit sizes the absolute cost is not. The numbers are at the call site so an author knows what a big pool would cost. - MoonLiveScript::releaseReporting: all three scripted bindings now hand back the bytes they reported when disabled. Only the effect did, which was an asymmetry this change introduced by fixing one of three paths. - sync() reports a DELTA rather than assigning the total: a binding may also own ScratchBuffers, and MoonModule states "don't mix addDynamicBytes with setDynamicBytes". Scripts/MoonDeck: - fountain, comet-trail, rain, ballpit. Between them they show that emit() takes a position and an angle the script computes per frame: a fixed nozzle, a moving emitter shedding a trail, emission scattered along an axis, and balls that pile up. Throw and pull scale with grid height, so a plume fills a 16x16 and a 128x96 alike. - check_taglines.py: README, docs/index.md and CLAUDE.md had drifted into four orderings of the same six platforms, one of which also demoted five of the six to secondary. They are all targets. An include cannot fix this because GitHub renders README.md itself, so the one home is enforced by a gate. Tests: - 12 cases for the pool: sizing, no-default-pool, no-allocation-on-tick, live resize, release, absent handle, a spark that comes back down, a full pool that stops rather than overwriting, slots that recycle, two effects with separate pools, a moving emit seed, and colliding balls that pile higher. - Two tests were removed rather than shipped: each passed with its own bug reintroduced, so neither could tell fixed from broken. Docs/CI: - Every entity in README's Credits now also appears on the doc page covering their part. FPP appeared nowhere in the repo at all; FastLED was absent from the primitives page that describes exactly what it is credited for. - Three misattributions corrected: the WLED Particle System was credited to @Brandon502/WildCats08, but git shows Damian Schneider (@DedeHai) wrote it. He is added to Credits and to the kernel and MoonLive pages. - Roadmap item 9b deleted (shipped) and rewritten with what landed, including the finding that structs were NOT needed: every pool operation is whole-pool or takes scalars, so a script never names a particle field. - Backlogged: capping the particle frame scale. Deliberately not done, because it would make motion lie about elapsed time and every stall it hides is a real defect elsewhere. WLED-PS takes the opposite side (no millis() anywhere), so its motion speed is a property of the frame rate. Reviews: - 🐇 CodeRabbit: uvX/uvY overflow. VALID and fixed. A script can write 65535 * 65535, which as int32_t is -131071, so a coordinate far off the right of the grid clamped to the LEFT edge after overflowing a signed multiply. 64-bit throughout now, with a regression test that fails when the read is put back to int32_t. - 👾 Reviewer, 4 findings, all fixed: the release-reporting asymmetry above; a duplicated draft comment; ballpit gating emission on a FRAME counter (10/s at 60 fps against 200/s at 1200, breaking the rule this branch documented) now clock-driven at 20/s on any device; and .mle headers over the two-line rule, trimmed on all four. - Cleared on inspection: releaseIfEmpty covers both new sinks, nextEmitSeed's atomic emits no lock guard, dims.x - 1 cannot underflow (the Layer gates on hasGrid), and the release ordering is correct.

changed the title
The pre-merge review found three places where documentation still described behaviour this branch had removed, plus the performance snapshot and lessons the merge gates ask for. Docs/CI: - architecture.md still said `fadeToBlackBy(255)` means CLEAR THIS FRAME. That sentinel was deleted earlier on this branch, so the page licensed exactly the bug the branch removed: someone writing the next clearing effect would have followed it, got a time-scaled fade, and seen the previous frame bleed through. Now states the rule the code states. - The MoonLive roadmap said "seven builtins" and listed `bounce` and `collide` under "not exposed, each with a reason". Nine shipped, and `ballpit.mle` in the same commit calls both. Corrected, with collide's measured N-body numbers carried over. - power-functions.md's `draw::fade` caller list named SphereMove (migrated off it here) and omitted Fireworks. Verified against the call sites: 13 either way, two names wrong. - StarFieldEffect's `blur` control was still described as a per-frame amount; it is a rate per reference frame. - platform_config.h (desktop) carried two paraphrases of the same "a host has no EMAC" comment. - performance.md gains this branch's snapshot: the two cost models side by side (metal.mle 59,600 us against fountain.mle's 1,093 us on the same 80x48, 54x), what makes the shader expensive (polarR wraps a real square root, ~3.5 us per pixel, called three times), collide's non-linear cost, and the frame deltas before and after the filesystem fix. - lessons.md gains three, each one that cost something to learn: a stateful effect is a jitter meter and a stateless one hides the same fault; standardising a duplicated sentence means deciding which version is TRUE first, since the most formal-looking one here was simply wrong; and a test that passes with its own bug reintroduced is worse than no test, which three tests on this branch each did before a control check caught them. Reviews: - 👾 Reviewer over the whole branch diff (88 files, 4 commits). Verdict merge-ready: "net-subtractive in the places that matter". Three findings and two nits, all documentation contradicting shipped code, all fixed above. Cleared on inspection: core stays domain-neutral (zero particles:: references outside the light domain), the '/' operator seam resolves by name through the builtin table rather than hard-coding a function, a non-particle effect pays one FrameTime::advance per Layer per frame, and the five example scripts are each a distinct shape rather than variations.

Brings the five commits released as PR #71 onto this branch, so the x86-64 JIT backend is developed against what shipped rather than against the state before it: fixed-pin claiming, scripted-control persistence, the MoonLive shader vocabulary, and particles. Four conflicts, all resolved by keeping both sides: - moondeck/event/_gates.py: this branch changed the desktop build gate to host_build_dir(); main added a "front pages agree" gate. Both wanted, so the new gate now runs against the host-specific build directory. - docs/backlog/backlog-core.md: both branches appended entries at the same point, with no overlap in subject (Windows repo-health and stdout encoding here; the GPIO-collision writeup from main). Both kept. - docs/metrics/repo-health.{json,md}: generated by the KPI gate on both sides, so neither version is authored. Took main's as the base; the next gate run rewrites both from this machine. Verified after resolution: desktop build clean, 1386 unit tests pass, all 25 scripts in moonlive/ compile. That last one was the risk worth checking, since this branch's own commit notes that x86-64 saves and restores its register pool around every call site, and main's particle and shader builtins are call-heavy. They fit. The x86-64 backend needs no work for main's new builtins: it lowers IrOp::Call generically through the shared moonlive_lower.h and names no builtin, so the nine particle calls and the '/' and '%' operators reach it without a backend change. NOTE for whoever merges this branch onward: check_prose.py reports 88 issues, all in this branch's own files (48 in moonlive_asm_host.cpp). They predate this merge and are not introduced by it, but they are a blocker for merging to main. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

Four things landed on this branch, in the order they were found.
An LED driver could silently take an Ethernet pin
ParallelLedwas configured withclockPin = 10, which on an ESP32-S31 istxd2, one of the four RGMII transmit lines. The i80 bus is always 8 or 16 bits wide, so spare lanes were parked on the clock pin and routed as data. Nothing could tell you: the pin map showed no claim.One GPIO, two bugs. A ColorLight panel would not light, and S31 Ethernet DHCP had been broken since 2026-07-26. Both fixed by the same change, both verified on hardware.
The architectural half is that fixed pins are now claimed like any other. A module declares them through
MoonModule::fixedPins()and the pin map reads them, so a collision is visible instead of silent. All three interfaces are covered: classic RMII (6 data pins, from IDF's own RMII Data Plane GPIO table), P4 RMII, and S31 RGMII (12 pads). Verified live on MM-Olimex at 100 Mbit.A scripted control keeps its value across a reboot
A MoonLive script's controls exist only after the script compiles, which happens in
prepare()— after persistence has already been applied. So a scripted grid always booted at its default. Fixed by a fifth scheduler phase that reapplies persisted values once the tree has settled. Verified on hardware: a 48x40 grid survives a reboot.Scripts get division, shaders and trails
/and%are operators now, at multiplication's precedence. Both lower to the host callmodalready used, so the operator costs nothing the capability did not: no ISA here has a divide. The parser resolves them by NAME through the builtin table, so core stays domain-neutral.Five builtins:
smoothstep,uvX,uvY,smin,fade. Each folds several host calls into one on the per-pixel path, which is the bar now that/covers the general case.Every trail in the system now fades at the rate the effect asked for, not at the speed the hardware renders.
Layer::fadeToBlackBytakes a rate and the Layer scales it by elapsed time. Three effects had hand-rolled that conversion and drifted into two versions of it; those copies are gone.metal.mleships as the example.Scripts get particles
A script sizes its own pool and calls whole-pool physics. Particle state lives outside the script arena in ScratchBuffers the binding owns, because a
Poolis eight parallel arrays and the 64-byte arena would hold about five particles.Nine builtins:
pool,emit,gravity,drag,step,age,render,bounce,collide.pool(n)is reachable only fromdefineControls(); called fromtick()it reports the live count and allocates nothing, which keeps a malloc off the render path.The headline is the cost model. On shiffy's 80x48:
fountain.mlemeasures 1,093 us againstmetal.mle's 59,600 us. It is the first script vocabulary whose cost scales with the objects rather than with the grid. Four examples ship: fountain, comet-trail, rain, ballpit.And one stutter that was always there
FileManagerModule::tick1s()calledesp_littlefs_infoevery second, on the render thread, to feed one progress bar. That walks every block of the partition, ~80 ms on an S3. Frame deltas went from83 78 80 79 82 66 72to83 85 85 83 84 87 85.It is pre-existing on main. Particles are what made it visible: a particle integrates a stall into its trajectory (one frame after an 80 ms gap moves every particle 6.7x its usual distance) where a shader just redraws from the clock and skips a frame invisibly.
Verification
All pre-commit gates green on each commit. 1386 unit tests. Every feature above was verified on real hardware: MM-Olimex (classic Ethernet), the S31 (RGMII), and shiffy (S3, the 80x48 wall).
Worth knowing about the tests: two were removed rather than shipped, because each passed with its own bug reintroduced and so could not tell fixed from broken.
Known gaps, recorded rather than hidden
draw::bluris a compounding spatial operation, so the carry pattern that fixed the others does not transfer; it needsdraw::bluritself to become time-aware. Recorded in the test with its reason.RandomEffectandStarFieldEffectare recorded per effect with reasons rather than widened for all 51. Their physics matches within 0.5% across 60/240/1200 fps; what differs is how a continuous fade quantises between discrete steps.
