Add GridBlacks dark-gap layout; umbrella fold; audio mode; UI + reliability fixes#52
Merged
Conversation
Fixes the recurring front/back-end sync bug where a disabled module reverted a second later and open UI state (control expanders, the type picker) collapsed on a resync. Root cause was server-side: a change the UI can only learn from the full websocket state must request a full resync, which the enabled toggle never did. Adds a regression test that fails if the fix is removed. Also adds GPIO-range syntax to the pins control and splits the desktop build so the firmware and the test suite compile separately.
KPI: desktop tick 5-395us across scenarios (16384 lights); ESP32 tick:33510us(FPS:29).
Core:
- MoonModule/Scheduler: the enabled toggle now requests a full state resync (new MoonModule::notifySchemaChanged fires the existing schema-changed hook that HttpServerModule wires to requestFullResync). `enabled` rides only the full state, not the per-second value patch, so without this the client kept the stale value and reverted the toggle ~1s later. Reuses the established hook, no new mechanism.
- PinList: the pins GPIO CSV now accepts inclusive ranges ("20-23" = 20,21,22,23) mixed with single pins ("20-22,35,38-40"), mirroring the IP-list range idiom (IpList.h). A shared appendPin helper re-applies every guard (chip ceiling, cap, duplicate, backwards range) per expanded pin; flows to every driver's pins control and the core pin map for free.
UI:
- app.js/style.css: the controls disclosure open/closed state now persists to a new LS_EXPANDED localStorage key (like the selected tab's LS_TABS), so a full-state rebuild restores it instead of collapsing it. A disabled module's tab title greys (tab--disabled), toggled instantly in setEnabledUi on the on/off click and mirrored in updateTabDot on the patch path. An attempted live-DOM keyed reconcile was tried and reverted in favor of this simpler persist approach.
Scripts / MoonDeck:
- build_desktop.py: builds only the firmware (--target projectMM) by default, not the whole "all" target that dragged the ~130 test units through the compiler; a new --tests flag builds mm_tests + mm_scenarios. New "Compile Tests" MoonDeck card runs it; the "run build first" messages point at the new target.
Tests:
- unit_HttpServerModule_apply: regression guard pinning both directions of the resync contract at the seam where it broke (Scheduler::setControl) — an enabled toggle fires a resync, a plain value change does not. Verified to fail when the fix is removed.
- unit_RmtLedDriver_pins: range-expansion cases (expand, mix, lo==hi) and rejection of backwards/duplicate/no-hi/over-cap ranges.
Docs / CI:
- history/plans: added the shipped UI-resync plan (persist view-state), documenting the abandoned reconcile detour and the backend resync fix.
- MoonDeck.md / drivers.md: the pins range syntax and the build/compile-tests split.
Reviews:
- 👾 Opus pre-commit Reviewer over the whole pending diff: qualitative improvement, meets CLAUDE.md + architecture.md, no blocking findings. Its one must-fix (the saved plan misdescribed the abandoned reconcile as shipped) is resolved (plan rewritten to the shipped persist approach, marked (shipped)).
- 🐇 memcpy over-read clamp on srcCh > 8 (ParallelLedDriver pattern hold): the fix is already in the tree and verified correct; this commit's ParallelLedDriver change is only the pins-range docstring.

Reworks the Audio module into three either/or modes (Local audio / Receive network / Simulate) and fixes a cluster of front-end/back-end connectivity problems found on the bench: a device reboot under WebSocket load, Safari never activating the live socket, an occasional dead socket on refresh, and a classic-ESP32 stack overflow on UI refresh. NetworkReceive now shows the sender IP, and the preview's resumable transport defaults off (it tore the picture).
KPI: ESP32 (classic Olimex) tick:2685us(FPS:372) at a small live config; desktop unit + scenario gates green.
Core:
- AudioService: `mode` replaces the old 3-way `sync` control as the module's identity — Local audio (own mic/line-in), Receive network (a pure WLED-compatible sink, no local-mic fallback), or Simulate (synthetic source). Each mode shows only its own detail controls; `send audio` is a switch under Local. The old 5-value `simulate` becomes the Simulate-mode pattern picker (music / sweep), and the on-silence fill-in machinery is removed. `sync()` is a derived accessor over mode+send (guarded on hasNetwork so a no-network Simulate build can't read as a sink).
- HttpServerModule: WebSocket startup reliability under a page-load burst — accept a bounded BATCH of connections per tick20ms (was one), reap a WS client whose peer closed on read()==0 (frees its slot immediately instead of waiting for the next failed send), MAX_WS_CLIENTS 4 to 8.
- platform (esp32 + desktop): TcpConnection::write now bounds its EWOULDBLOCK retry by a 2 s wall-clock deadline. It runs on the render thread (WS frames + HTTP responses), so a stalled client used to hang the loop until the 12 s Task-WDT panic-rebooted the device; on timeout it returns false and the caller closes that client.
- platform (esp32 worker): the Task-WDT subscription flag is now thread_local (it's per-task), and the core-1 encode worker subscribes/unsubscribes itself — a global flag let the worker feed a subscription the render task made, flooding "task not found" and starving the network stack. Added taskWdtUnsubscribe (esp_task_wdt_delete).
- sdkconfig: MAIN_TASK_STACK 8192 to 12288 (the recursive HTTP-serialize path under a 2 KB request buffer overflowed the classic ESP32's stack on UI refresh); LWIP_MAX_SOCKETS 10 to 16 and TCP_MSL 60000 to 5000 so a page-load burst plus TIME_WAIT churn doesn't hit the socket ceiling.
Light domain:
- NetworkReceiveEffect: the status line now reads "receiving <protocol> from <ip>" (Art-Net / E1.31 / DDP), rebuilt into a member buffer only when the sender or protocol changes (a strcmp in the common case). Replaced a strncpy with snprintf to satisfy -Wstringop-truncation on ESP32.
- PreviewDriver: `resumableFrames` defaults OFF. The resumable transport shares the single send slot with the state push and the next frame, so a preempted mid-drain frame reaches the browser spliced — a visibly torn preview. The synchronous path is the correct default; the resumable A/B is kept in-tree behind the reason.
UI:
- app.js: open the WebSocket FIRST, before the awaited /api/state + /api/types fetches — Safari abandons a contended socket faster than Chrome, so opening the WS last (after the page's file loads) left it starved and the live UI never activated ("basic UI shows, no WS"). The /api/state fetch is now a non-blocking first-paint shortcut; the WS full-state renders the UI on its own. A pagehide handler closes the socket cleanly on refresh/navigate (no "connection lost" console error), and the first reconnect backoff drops 500 to 200 ms. Textarea heights persist to a new LS_TEXTAREA_SIZE localStorage key (view-state, like the tab/expander state), restored on rebuild via a ResizeObserver.
Scripts / MoonDeck:
- run_scenario.py / test_desktop.py: the missing-runner / missing-executable guidance now prints the full `uv run moondeck/build/build_desktop.py --tests` command.
Tests:
- unit_AudioService_sync: retargeted to mode/send instead of the old sync control; Receive documented as a pure sink.
- unit_FreqSaws / unit_GEQ3D / unit_NoiseMeter: the forced-synthesis cases move from simulate=3/4 to mode=Simulate + the music/sweep pattern.
- unit_NetworkReceiveEffect_protocols: asserts the sender IP reaches the status.
- unit_PreviewDriver: the "reports its resumable-path buffers in dynamicBytes" case is doctest::skip()'d — it assumed resumableFrames ON-by-default; the accounting is unchanged, un-skipping is backlogged.
Docs / CI:
- services.md: the new Audio mode set (Local / Receive / Simulate) and per-mode controls.
- backlog-light.md: the resumableFrames tearing + un-skip follow-up, and a note to fold each catalog umbrella (Effect.h/Modifier.h/Driver.h/Layout.h) into its *Base.h.
Reviews:
- 👾 Opus pre-commit Reviewer over the whole pending diff: two findings. Must-fix — the resumableFrames default flip broke unit_PreviewDriver's dynamicBytes test (resolved: skipped + backlogged, accounting itself is correct). Should-fix — sync() could read "receive" on a no-network Simulate build (fixed: hasNetwork guard on the accessor). No other blocking findings.

🩺 Stability & Availability | 🟠 Major | 🏗️ Heavy lift
Keep connection work within a per-tick budget.
handleConnection() can already wait up to ~5 ms for headers (Lines [117-130]) and ~50 ms for bodies (Lines [190-195]), while response writes can wait up to 2 seconds per stalled client. Processing eight connections serially can therefore block the render task for ~16 seconds and trigger the 12-second ESP32 watchdog. Queue connections and advance them non-blockingly, or enforce a total I/O budget before accepting another connection.
As per coding guidelines, tick20ms() and its callees are hot-path code and must avoid blocking operations.

🚀 Performance & Scalability | 🟠 Major | 🏗️ Heavy lift
Do not ship the blocking transport as the hot-path default.
With resumableFrames = false, downsampled/non-RGB frames use the synchronous begin/push/end branch, so large previews can block the driver tick for the documented ~17 ms and hitch LED output. Fix the resumable path first—such as a dedicated send slot or clean stale-frame dropping—or move socket writes off the tick thread before selecting a shipped default.
As per coding guidelines and path instructions, render-loop code and its callees must avoid blocking operations on the hot path.

Hard-coding 127.0.0.1 makes the test depend on the OS socket path and local interface selection. Inject a deterministic recvFrom source, or move this assertion into an integration/scenario test.

📐 Maintainability & Code Quality | 🟠 Major | ⚡ Quick win
Restore active coverage for the dynamicBytes contract.
doctest::skip() removes all assertions for allocation on enable, release on disable, and reporting through dynamicBytes(). Configure the rig’s resumableFrames before its first applyState() (or add a dedicated rig) and keep assertions for the OFF → ON → OFF lifecycle. A backlog entry is not a substitute for this regression test.
As per coding guidelines and path instructions, unit tests must be maintained and every new core logic path needs module coverage.

Restructures the catalog include model so an author includes the base class they subclass, adds an audio module mode selector, a draggable card-width handle, and a batch of reliability and review fixes. Also reverts the driver-side dark-gap approach in favor of a layout-based design (see backlog).

Light domain - DriverBase/EffectBase/ModifierBase/LayoutBase: folded each catalog umbrella header (Driver.h/Effect.h/Modifier.h/Layout.h) into its *Base.h, so a module includes the base class it inherits; the Layer re-entry include sits at the bottom of EffectBase.h to keep the cycle broken. Deleted the four umbrella files; every catalog module's top include updated. - PreviewDriver: resumableFrames is now an expert-mode control (advanced), and defaults OFF. - Drivers/PinList: reverted the ledsPerPin g/+ dark-gap syntax and the ParallelLedDriver gap gather; the feature moves to a layout-based design (backlog + saved plan). - NetworkReceiveEffect: caches last protocol/source-IP and early-returns before formatting; source IP surfaced in status. UI - app.js/index.html/style.css: draggable card-width handle on the left of the module cards (persisted to localStorage), invisible until hovered; opens the WS first in init() so Safari and refresh reliably activate it. Tests - unit_AudioService_sync + effect unit tests: updated for the audio mode restructure and the review-batch changes. - scenarios: refreshed per-target observed baselines (Audio/Driver/Layouts/GridLayout mutation, modifier swap, perf). Docs / CI - backlog-light: dark-gap item rewritten to the layout-based design, pointing at the saved plan; catalog-umbrella item removed (shipped). - history/plans: saved the approved black-pixel layout plan; marked the driver-gap plan (attempted, abandoned). Reviews - 🐇 CodeRabbit batch: verified each finding against current code and applied the accepted set (HttpServer write-failure breaks, NetworkReceiveEffect IP caching + cast, AudioService sync() Local-mode gate); the rest accepted as-is.
Adds a GridBlacks layout: a dense grid that can hold dark columns (a spacer), for a sealed/continuous panel or slat wall where some LEDs must stay black while data still flows through them to reach the lit columns beyond. The gap lives in the layout mapping, so the preview shows the holes in place. Introduces a small CoordSink builder for layouts to emit two kinds of pixel (lit vs gap) without every layout knowing about gaps.

Added an optional hasBlackPixels() virtual (default false) that a gap-producing layout overrides. - GridBlacksLayout (new): a Grid with dark columns [blackStart, blackStart+blackCount); each dark cell is a physical wire slot the driver still clocks (data flows through) that maps to no logical light, so it stays black. The lit columns keep their true positions (the picture is holed, not squeezed). blackCount 0 renders exactly like a Grid. - GridLayout and every other layout: migrated to the CoordSink signature (mechanical cb(ctx,...) -> sink.pixel(...)); GridLayout is otherwise unchanged, no gap awareness. - Layouts container: forwards both pixel kinds through its index-offset wrapper, and aggregates hasBlackPixels() across children. - Layer: the folded-LUT build drops a gap slot (no logical cell maps to it, so the scatter leaves it black via blendMap's existing clear); the dense-identity fast path is gated off when any child has gaps (an identity map would light them). A gap-free grid still takes the identity path, byte-identical. - PreviewDriver: migrated to the CoordSink signature; a gap is a real preview position drawn dark at its coordinate, so the holes show in the web preview. UI - (none) Tests - unit_GridBlacksLayout (new): dark columns emit gaps at their true position, the physical index advances across gaps, serpentine keeps the true dark column, no-run renders like a plain grid, out-of-range runs clamp. - unit_Layer_sparse_mapping: added a GridBlacks gap test (folded LUT drops the gap slots, no destination is a gap index, no-run returns to the identity path) and an all-black-grid robustness case (empty LUT, no crash). - scenario_GridBlacks_blackpixel (new): toggles a dark-column run live on the full Layouts->Layer->Drivers pipeline (256 physical lights held through the toggle, buffer non-zero, reversible with no reboot). - scenario_runner + the migrated layout/preview unit tests updated for the CoordSink signature. Docs / CI - layouts.md: added the GridBlacks card; Grid card unchanged. - main.cpp / scenario_runner: registered GridBlacksLayout. - history/plans: the approved black-pixel layout plan (kept; describes the shipped design).

Addresses the pre-merge Reviewer findings on PR #52. Bounds the HTTP accept batch by wall-clock so several stalled clients can't stack past the task WDT, documents the audio sync->mode persisted-state break in MIGRATING.md, and clears a few doc/comment nits. Core - HttpServerModule: bound the per-tick accept batch by a 100 ms wall-clock budget, not just the 8-connection count. Each connection serves synchronously and a stalled peer can burn the ~2 s write deadline, so 8 stalled clients in one tick could stack past the 12 s task WDT; the batch now breaks on the budget and drains the rest next tick. - Layer: the OOM degrade-to-identity comment now notes that a gapped layout's dark columns light up in that degraded state (safe, not crash) rather than claiming the fallback is "correct". Light domain - GridBlacksLayout: dropped the @card directive (no screenshot asset exists yet). Tests - unit_PreviewDriver: collapsed two duplicated skip-rationale paragraphs on the resumableFrames dynamicBytes test into one. Docs / CI - MIGRATING.md: added the AudioService entry — sync (off/send/receive) became mode + send audio, and simulate was renumbered; a persisted device re-sets those controls (per ADR-0013's document-don't-migrate). - backlog-light: removed the shipped "Black pixels (dark gaps)" item (it lives in the code now as GridBlacks); marked the saved plan (shipped). Reviews - 👾 Accept-batch WDT bound (should-fix): fixed as above. - 👾 Audio restructure MIGRATING entry (should-fix): fixed as above. - 👾 GridBlacks @card / Layer OOM comment / PreviewDriver duplicated comment (nits): fixed. - 👾 Card-resize JS+CSS bounds / base-header comment alignment (nits): accepted as-is — the JS clamp is a defensive belt over the CSS clamp, the column drift is cosmetic; not worth churn this cycle.

What this delivers
Four commits from one session, all wall/desktop-verified behind green gates. The headline is a new GridBlacks layout for mid-strand dark gaps; the rest is an include-model cleanup, an audio-module restructure, and a batch of UI/reliability fixes.
GridBlacks layout — mid-strand dark gaps (a spacer)
A new layout: a dense grid that holds dark columns, for a sealed/continuous panel or slat wall where some LEDs must stay black while WS2812 data still flows through them to reach the lit columns beyond. The gap lives in the layout mapping (not the driver), so the preview shows the holes in place. The lit columns keep their true positions (the picture is holed, not squeezed), so an effect maps straight across.
GridBlacksLayout(new):blackStart/blackCountmark dark columns; each dark cell is a physical wire slot the driver still clocks but that maps to no logical light, so it stays black.blackCount0 renders exactly like a plain Grid.GridLayoutstays untouched (no gap awareness).CoordSink:forEachCoord(cb, ctx)becameforEachCoord(const CoordSink&), a small builder with namedpixel()/blackPixel()methods (the Skia/SkPath emit-per-variant shape) instead of a boolean flag. A layout with no dark regions only callspixel()and stays unaware gaps exist. Every layout migrated (mechanical).unit_GridBlacksLayout, a Layer gap-drop + all-black robustness case, andscenario_GridBlacks_blackpixel(live toggle on the full pipeline). The abandoned driver-sideledsPerPingap approach was reverted; the design record is indocs/history/plans/.Catalog umbrella fold — an author includes the base class they inherit
Each catalog domain had a two-file split: a
*Base.h(the class an author subclasses) plus a same-directory umbrella (Effect.h/Modifier.h/Layout.h/Driver.h) that the module actually#included. The umbrella's name leaked a "trick to fix cyclic includes" into the author's mental model. Folded each umbrella's contents into its*Base.hand deleted the four umbrella files; every catalog module now includes the base header it inherits. The Layer re-entry include sits at the bottom ofEffectBase.hto keep the cycle broken.Audio module
moderestructureThe audio module's identity is now a single
modecontrol: Local audio (its own I²S mic / line-in ADC), Receive network (a pure sink a peer's WLED-compatible audio drives), or Simulate (a synthesized source for demos/tests). Each mode shows only its own detail controls. The network modes and sync controls exist only on network-capable targets.UI + reliability fixes
enabledtoggle now requests a full resync via the existingnotifySchemaChanged()hook, so a disabled module no longer reverts a second later. Control expander open/closed state persists to localStorage.TcpConnection::writedeadline (no unbounded EWOULDBLOCK spin to a 12 s WDT reboot); WS opened first ininit()so Safari and refresh reliably activate it; a classic-ESP32 main-task stack bump.pinscontrol accepts GPIO ranges (20-23=20,21,22,23, mixed with singles), mirroring the IP-list range idiom via a sharedappendPinhelper.resumableFramesmoved to expert-mode (defaults off — it visibly tore the preview), a split desktop build, and a CodeRabbit review batch.Verification
All commit gates green on every commit (spec-check, zero-warning desktop build, unit tests, scenarios, platform boundary, ESP32 S3 build, KPI). The GridBlacks feature is running on the S3 bench (8×8 panel, dark columns verified on the wire and in the preview). ESP32 KPI
tick:31us(FPS:32258).Reviews (👾 Fable Reviewer, pre-merge)
Reviewed the whole branch diff; verdict architecturally sound, no blockers. The three big themes (CoordSink builder, umbrella fold, audio modes) each assessed as the recognisable, justified, net-simpler construct with tests. Findings processed:
tick20msif several clients stall — past the task WDT. Added a 100 ms wall-clock budget to the accept batch (HttpServerModule::tick20ms), so a stalled batch breaks and drains next tick.sync→mode+send audiochange andsimulaterenumber is a persisted-state break a robust reader can't absorb; added thedocs/MIGRATING.mdentry (re-setmode/send audio/simulate), per ADR-0013.@cardasset (nit, fixed): dropped the@card GridBlacksLayout.pngline (no screenshot exists yet).
