Conversation
A board with PSRAM now keeps at least 100 KB of internal RAM free, with a 50 KB block, for WiFi, the web server and the UI. On the S3 that went from 66 KB to about 150 KB, and LCD-MM from 75 to over 100 fps. A classic ESP32 with the UI and preview open keeps 40 to 55 KB instead of 12 to 23.

| Plan of 2026-10-21, every step done 2026-10-22. An ESP32-S3 driving 3,840 lights through a pin expander ran with 63 KB of internal RAM free and a 30 KB largest block, enough for a TLS handshake to fail and a UI refresh to crash it. The goal: as much internal RAM free as the board allows, never less than 100 KB free with a 50 KB largest block. |

Resolve an accessor before accepting its receiver's comment.
For owner_->snapshotRef(), _referenced_field can find owner_ before snapshot. If owner_ has a /// comment, named uses that comment and skips the comment on snapshot. Resolve accessor-backed arguments first, then use a directly named field or the call-site comment as appropriate. The new fixture leaves owner_ undocumented, so it does not cover this case.

🩺 Stability & Availability | 🟠 Major | 🏗️ Heavy lift
Allow embedded sends to make progress below the fixed threshold.
The 100 KB internal-memory floor makes kSendHeadroom 50 KB. The PR reports 40–55 KB free on a classic ESP32 with the UI open. If free memory stays below 50 KB, embedded bodies and state streams stop sending; the embedded-send drain also refreshes its stall timer on every wait. A page refresh can therefore remain incomplete indefinitely. Use a threshold suited to boards without PSRAM, or permit bounded progress and a finite wait. Based on the reported classic-ESP32 memory range in the PR objectives.

Route shifted frames with more than eight pins to the whole-slot encoder.
ParallelLedDriver::encodeRows calls encodeWs2812ShiftData for every shifted frame. Since that function returns when physPins > 8, configurations with 9–15 shift-mode pins leave the prefilled data words unchanged and can keep the strands dark. Dispatch these configurations to encodeWs2812ShiftSlots, or implement equivalent handling inside encodeWs2812ShiftData.

A show that moves layer windows from a service now runs at full speed: a modifier's change rebuilds only its own layer, a service's writes are never saved, and a layer at opacity 0 costs nothing. On shiffy (3,840 LEDs) the show went from 1.3 to 1.7 s a frame to 44 ms, on a 64x64 HUB75 Waveshare from 273 to 43 ms, and Art-Net from the desktop no longer freezes. MoonLive scripts now live in project folders that mix kinds, such as moonlive/projects/hpwit/.

This was the INT_WDT/TG1WDT reset with a double exception on shiffy right after a config save. - Teensy defines ptrIsPsram. **Light domain** - ModifierBase answers Parent; Drivers records the first layer's shape it sized from and re-prepares in onTreePrepared only when it changed, and only while enabled. - NetworkSendDriver restarts its send task only when its destinations change, compared by the host text and addressing, so a named host keeps its stream too. - A layer above the bottom at opacity 0 neither renders nor blends (Layer::contributes, Effects::tick, Drivers::blendLayer). - hpwit's ten effects in moonlive/projects/hpwit/, each with controls, twinkle-stars and particle-fountain covering the whole canvas; hpwit-show.mls plays them, voronoi and the mandala taking turns per scene by opacity. The StadBeest effects, palette and autopilot in moonlive/projects/stadbeest/; stadbeest-fire is palette 65. **UI** - The script picker fetches a script from its catalog folder and names a collection by its folder. **Scripts/MoonDeck** - run_live_scenario: write_file `from` a repository file, a per-step `settle`, and `--keep` to leave what a scenario built running; the in-process runner takes `from` too and rebuilds the scope prepareScope names. - gen_help registers the cursor kinds libclang's Python bindings lack, the CI check_docgen crash; screenshot_modules finds a script anywhere under moonlive/. - MoonWalk: a fresh agent session per branch, and after a large commit. **Tests** - unit_Scheduler_prepareScope (scopes, merging, widening, a removed scope, live writes), unit_RegionModifier_prepareScope (a Region rebuilds only its layer, verified red with the old whole-tree scope; Drivers re-prepares only on a shape change), a live slot write saves nothing, a script reads its file only after an announced change, AudioService and NetworkSend keep their resources through an unchanged prepare, an invisible layer is not rendered. - The script tests walk all of moonlive/ by extension; IR golden table re-captured for the moved and edited scripts. - Two flaky tests fixed: FixedPointEffect's demos judged with the zoom off, the worker seam waiting for each wake rather than a fixed 5 ms. - improv smoke test: not triggered. **Docs/CI** - Plan "Prepare only what a change reshapes", with its measurements; moonmodule.md, moonlight.md, testing.md, MIGRATING (palette numbers), moonlive/README (project folders); present/index.md keeps generic rules only, its Next items in the backlog; the two plans not started are named so. **Reviews** (Fable, working diff) - NetworkSend's same-destination check failed for named hosts: done, compared by host text and mode, named host tested. - Orphaned doc comments in five files: done. - moonmodule.md said one pending scope: done, four. - The enabled pseudo-control saved on a live write: done, test extended. - The 503 test passed with no file served: done, at least 16 whole. - Drivers re-prepared while disabled: done, guarded. - A failed script re-read its file every prepare: done. - gen_help relied on a private attribute: done, guarded. - The slot count restated the socket setting: done, it names CONFIG_LWIP_MAX_SOCKETS. - Hand-rolled operator!=: done, defaulted ==. - Palette 64/65 swap: done, MIGRATING line. - Plan still named not started: accepted, the product owner's call. - Interrupt-safety change undocumented: done, in this message.

Preserve an empty catalog folder.
If a script sits directly under moonlive/, the catalog sends folder: "". This || group fallback changes that valid folder to effects, so mlRepoPath requests moonlive/effects/example.mle instead of moonlive/example.mle. Fall back only when the catalog entry is missing. Make mlRepoPath omit the folder separator when the folder is empty.

A service script reads JSON from the internet (the weather, a price, a score, a headline), builds documents of its own from its text, and sends them to this device or another, live and never saved. hpwit's show and the StadBeest autopilot now set up every part's look themselves, a layer per look with crossfades, and a script a document names but the device lacks is downloaded by the open page. Every ESP32 now speaks HTTPS, and a board without PSRAM starts a TLS session only while internal RAM holds one, handing MoonCloud's post to the page otherwise. KPI: 256lights | Desktop:2406KB | tick:8/8/7/2/8/7/280/7/7/10us(FPS:125000/125000/142857/500000/125000/142857/3571/142857/142857/100000) | ESP32:2151KB | src:338(86589) | test:255(59441) | functions-over:359 Commit: src +1966/-266 lines | test +1715/-79 lines | code findings 1663 -> 1654 (complex function -1, duplicated block -6, large stack frame -1, mutable static state -1) | duplicated lines 3338 -> 3315 (-23) **Core** - JsonFetch: documents held by generational handle in a 16-slot table; parsed from a script's own text, fetched from a URL and kept fresh (stale-while-revalidate), or answered by a push. One worker task (6 KB stack, measured peak about 4.4 KB) runs the network through two SPSC rings, starts with the first request and stops once no feed is held and nothing is on its way. - Pushes: to this device through Scheduler::applyLive, applied at the frame boundary as StateSource::Live and never marked dirty; to another MoonLight as PATCH /api/state?live=1; to any URL as a POST. A push to a busy target waits, the newest replacing older ones. - JsonUtil: RFC 6901 JSON Pointer read, set (mkdir -p), copy and append; decimals read as fixed point from the number's text, in integer arithmetic, so nodes stay 24 bytes; \uXXXX decodes to UTF-8; quoted numbers read as parseFloat does; one writer, json::write, replacing StateDocument's copy. - Platform: httpFetch (method, URL, body, answer) on ESP32, desktop (curl, WinHTTP) and Teensy; tlsRoom gates HTTPS on boards whose TLS sits in internal RAM; the ESP32 resolves .local over mDNS; cross-signed certificate verify on, so Google Trust Services chains verify. httpsPost is gone. - MoonCloud: a route per board (Direct, Page, DirectOrPage), posts on the JSON worker, a ticket per request so MoonStats and MoonTalk each read their own outcome, settled by a non-blocking field read. - Missing scripts: a module naming a shipped script the device lacks lists it on System's hidden `missing scripts`; the name leaves when its file lands. - HttpServer: `?live=1` read as a whole query parameter; deleting a path that names nothing answers 404. - MoonLive: the `json` type, raw string literals, a per-script string pool sized to its literals (up to 16 KB), and the JSON builtins in the service table. **Light domain** - Drivers recompiles the running palette script when its file changes; the live-palette scan is one struct rather than four statics. **UI** - The open page downloads every missing script through the picker's own path, each at most once a minute, finding the control by its name. **Scripts/MoonDeck** - jsondemo.mls shows four free feeds as scrolling text; hpwit-show.mls builds its look; plasma-wander, mandala, spinning-squares and voronoi advance their phase by elapsed time, so a speed change no longer jumps. - stadbeest-autopilot.mls pushes each part a layer per look, fades them through encoder6 to encoder8, and pushes again every 30 s. - sdkconfig_fragments: a build directory regenerates its sdkconfig when a fragment changes. A Serve for OTA card serves a firmware for a board to fetch. **Tests** - New: JsonUtil pointer and edits, JsonFetch (handles, feeds, pushes, coalescing, retirement, posts), the service end to end, httpFetch and the TLS gate, missing-script download (JS); additions for StateDocument live, the live route, the 404, MoonCloud routes and tickets, MoonStats and MoonTalk outcomes, Drivers' palette recompile. Shared fixtures for the route, SD-card and script-writing tests. **Docs/CI** - moonlive.md gains JSON documents in a service; integrating.md and openapi.yaml the live parameter and the 404; multi-board-installation.md the StadBeest looks; MIGRATING.md the encoder remap; MoonWalk "Show live data from the internet" in Integrate; help.json regenerated; the plan's Where it stands. **Reviews** - Reviewer: a json handle kept across a recompile could name another document; fixed with generational handles, tested. - Reviewer: a missing name left only through a compile; fixed, it leaves when its file lands, tested. - Reviewer: JSON nodes grew 4 bytes; fixed, decimals derive from the text, nodes back to 24 bytes. - Reviewer: live documents queued at scheduler stop were never answered; fixed, answered as refused, tested. - Reviewer: MoonStats and MoonTalk shared one outcome; fixed with tickets, tested. - Reviewer: JsonFetch is a service in core/util; skipped, HostResolver in core/util owns a worker task too. - Reviewer: a push that never went returned a valid handle; fixed, it reports status 0, tested. - Reviewer: `?live=1` matched by substring; fixed, read as a whole parameter, tested. - Reviewer: the plan said the worker runs on core 1; fixed in the plan. - Reviewer: the plan's name still says "(not started)"; deferred to the product owner. - Pre-commit: prose, docgen, check_code and ESP32 freshness failed; fixed (sentences shortened, the new appendix moved into member comments, functions split, statics and blocking sites cut, the S3 image rebuilt), then build, tests, check_code, docgen and prose rerun clean.

…steady memory A JSON document a service edits forever now holds the memory of one edit, so the demo no longer runs a board out of RAM within days.

Check response completion before returning success.
If the peer closes early, esp_http_client_read() can return 0 before the complete response arrives. Both drainAnswer and readAnswer then accept an incomplete response. exchange can report the HTTP status as success even though the response was cut off. Check esp_http_client_is_complete_data_received(client) when a read or probe returns 0; keep the existing overflow check. Espressif uses this separate completion check in its OTA reader. (github.com)

A JSON feed or push on an ESP32 whose answer ends before its declared length or last chunk now reads as failed rather than as a shorter answer. A test's encode worker no longer ticks a driver after the test has destroyed it, the data race ThreadSanitizer reported in CI. KPI: unchanged; desktop tick and flash as in the previous commit (the ESP32 change adds one completeness check). Commit: src +8/-2 lines | test +3/-1 lines | duplicated lines 3315 -> 3315 (+0) **Core** - ESP32 httpFetch: an answer framed by a Content-Length or chunks counts only once IDF confirms it complete; one the server ends by closing, as MoonLight's own state route answers, stays whole when the reads end. **Tests** - RegionModifier prepare-scope rig releases Drivers before its members destruct, so the encode worker stops before the driver it ticks goes. - The repeated-edit test's comment within 30 words. **Reviews** - CI: ThreadSanitizer data race in tickChildren from the prepare-scope test; done, the rig releases Drivers first. - CodeRabbit: a zero read accepted without IDF's completeness check; done for a framed answer; a close-delimited one is kept whole, since requiring the check there fails every push to another MoonLight. - CodeRabbit: the repeated-edit comment over 30 words; done. - Checks: desktop tests, docgen and prose pass; esp32s3-n16r8 builds clean and is fresh; ThreadSanitizer needs Linux, so CI confirms the race fix.

Internal RAM on the ESP32. A board with PSRAM now keeps at least 100 KB of internal RAM free, with a 50 KB largest block, for WiFi, the web server and the UI. An ESP32-S3 driving 3,840 lights through a pin expander went from 63 KB free and a 30 KB block to 150–155 KB and a 108 KB block with the UI open, and from 75 to 102–107 fps. A classic ESP32 with the UI and preview open keeps 40–55 KB instead of 12–23.
A change rebuilds only what it reshapes. A show that moves layer windows from a service runs at full speed: a modifier's change rebuilds only its own layer, a service's writes are never saved, and a layer at opacity 0 costs nothing. On shiffy (3,840 LEDs) hpwit's show went from 1.3–1.7 s a frame to 44 ms, on a 64x64 HUB75 from 273 to 43 ms. MoonLive scripts live in project folders that mix kinds, such as
moonlive/projects/hpwit/.MoonLive services read and send JSON. A service script reads JSON from the internet (the weather, a price, a score, a headline), builds documents of its own, and sends them to this device or another, live and never saved. hpwit's show and the StadBeest autopilot build every part's look themselves, a layer per look with crossfades, and a script a document names but the device lacks is downloaded by the open page. Every ESP32 speaks HTTPS; a board without PSRAM starts a TLS session only while internal RAM holds one, and hands MoonCloud's post to the page otherwise.
Plans: Internal RAM on the ESP32, JSON in MoonLive services
What changed
platform::InternalRamObjectfor what a cache-safe interrupt reads; the LCD-MM ring sized by its lead over the wire; embedded files stream across ticks from 8 send slots and wait while internal RAM is low.JsonFetchholds documents by generational handle, with one worker task (6 KB stack) that starts with the first request and stops once no feed is held;JsonUtiladdresses and edits by JSON Pointer (RFC 6901) in integer arithmetic; a push to this device applies live at the frame boundary, to another MoonLight asPATCH /api/state?live=1, to any URL as a POST.httpFetchclient on ESP32, desktop (curl, WinHTTP) and Teensy;.localnames resolve over mDNS on the ESP32; cross-signed certificate chains verify.Tests

ESP32-S3 N16R8 (shiffy, 3,840 lights), a Waveshare 64x64 HUB75, an ESP32-P4 with Ethernet, a classic Olimex ESP32, a Dig-Octa: the JSON demo's four feeds, hpwit's show and the RAM floors. Not yet seen on hardware: the StadBeest's eyes and mouth.
