Conversation
Every file upload, to flash or to the SD card, now streams a slice per tick, so a slow client can no longer freeze the lights or reboot the board through the watchdog. On the Teensy, host names in NetworkSend, OSC, audio sync and MIDI resolve, and uploads run ten times faster after a QNEthernet flow-control fix. Two new plans: streams (pictures, recorded shows and live input) and audio-reactive live performance.

Review comments at @docs/work/present/Plan-20261013 - Audio reactive live
performance.md:
- Line 35: Update the `MidiFrame` documentation to define note starts and ends
as ordered events that preserve repeated events for the same pitch between
frames. Update the unit-test description to include two note-on/note-off cycles
for one pitch between frames.
- Line 115: Update the ToF zone-grid prerequisite in the plan to require a
measured VL53L8CX read strategy that does not stall the render thread; evaluate
suitable options such as SPI, a lower ranging rate, or moving reads off the
render core rather than requiring a non-blocking read specifically.
Review comments at @docs/work/present/Plan-20261013 - Streams, every frame from
outside.md:
- Line 70: Revise the G1 wiring-order description to define it as the inverse of
the base layout mapping, before layer modifiers are applied; preserve modifier
transforms in the subsequent layer mapping so mirror and rotation do not cancel.
Add a non-identity modifier case to the acceptance checks, and lower the
severity to minor because this is a plan defect rather than a runtime
regression.
Review comments at @src/platform/teensy/platform_teensy.cpp:
- Line 501: Update the Ethernet-disconnection path in the lookup function
containing this guard to clear g_dns and advance its generation before returning
Failed, so reconnecting starts a fresh lookup and callbacks from the previous
connection cannot provide an answer.

Lights streamed over Art-Net, E1.31 or DDP now arrive whole far more often: Network Receive drains packets as they come and reports packets and frames per second, and Network Send spaces its packets so access points and Ethernet receivers keep up. A board receiving a stream no longer loses its network to a stuck latch, and a new mapped_by setting takes frames the sender already mapped (xLights, FSEQ, Network Send).

Commit: src +504/-147 lines | test +4779/-8 lines | code findings 1632 -> 1629 (blocking call on the render path -2, large stack frame -1) | duplicated lines 3656 -> 3654 (-2)
**Core**
- TryLock releases with an exchange: on an ESP32 with PSRAM a plain store raced the emulated read-modify-write and left the latch set with no owner, which froze the receive task and took the WiFi stack down with it.
- Platform: UdpSocket::waitReadable (select on desktop and ESP32, none on the Teensy) and sleepUs on a worker task (a one-shot esp_timer on the ESP32), so a task waits on sockets and paces below the scheduler tick without busy-waiting.
- CONFIG_LWIP_UDP_RECVMBOX_SIZE 6 -> 32 on every board; P4 Ethernet DMA 30 receive buffers of 1600 bytes, transmit kept at 10 (30 rebooted a sending P4).
- Teensy: an in-flight host-name lookup is abandoned on an Ethernet drop, so a reconnect resolves afresh.
**Light domain**
- Network Receive: a receive task on core 1, mapped_by (receiver or sender) with the path in the status ("one copy" or "mapped twice"), read-only packets_per_s and frames_per_s per second of elapsed time.
- MappingLUT::gatherFromPhysical places a sender-mapped frame, 7.3 -> 4.5 ms at 12,288 lights on the S3.
- Network Send: packet_gap (default 500 us) paces a frame's packets from a send task, clamped to fit the fps period, with a backoff on a full transmit queue; a gap of 0 or a board without tasks sends the burst from the tick.
- DdpPacket names the push flag, and its parser reports it.
**Scripts/MoonDeck**
- run_live_scenario: --board NAME=HOST for scenarios over several boards, steps marked with a device, read values on measure steps, observations keyed by the board combination, every board restored.
**Tests**
- Receive: sender and receiver mapping on serpentine, 3D and identity layouts, the status path, the counters and their per-second rate.
- Send: a gap spaces the packets from a task, a gap of 0 bursts from the tick, a long gap fits the fps period, a correction that grows the buffer under a paced send.
- Scenarios: scenario_NetworkReceive_two_boards (sizes, layouts, mapping, layers, protocols) and scenario_NetworkSend_one_sender_many_receivers, run on S3 WiFi and P4 Ethernet in all four pairings and on the Teensy.
**Docs/CI**
- Cards for mapped_by, the counters and packet_gap; testing.md on several boards; the Streams plan records where it stands, G5 (sender mapping skips the board's mapping), the channel-data sink FSEQ shares, and a backlog from the measurements; backlog-light gains the identity correction.
- CLAUDE.md: the contributed pull request size rule, which removes nothing since it states a limit the review process already implied; "Each check runs once per commit" as the gate rule's headline.
**Reviews**
- 👾 corrected_ reallocated under the running send task: done, resizeCorrected stops and restarts it; regression test added.
- 👾 waits reachable from non-blocking ticks: done, the pause and backoff live only in sendFrame<true>, the lock wait only in drainSockets<true>.
- 👾 single-core comments contradicted the platform: done.
- 👾 mangled include comment: done.
- 👾 torn destination address across cores: done, no refresh while the task sends.
- 👾 rate window not reset on prepare: done.
- 👾 mapped_by without an enum: done, MappedBy.
- 👾 two paragraphs run together in testing.md: done.
- 👾 dashes in edited files: done, an em-dash in a test name and six ranges in drivers.md.
- 👾 the push flag read beside the parser, a stale drain-bound name: done, the parser reports it; kMaxPacketsPerDrain.
- 👾 effectiveGap arithmetic: done, the same chunk as sendFrame, the bound commented.
- 👾 the passthrough send path undocumented: done.
- 👾 the PR-size rule names no subtraction and the stacked-PR sentence had two homes: the rule removes nothing (said above); the plan now links CLAUDE.md.
- 👾 a fixed wait in a loopback test: done, it polls on the last packet landing.
- 🐇 Teensy lookup survives an Ethernet drop: done.
- 🐇 MidiFrame loses repeated hits of one pitch: done, ordered events, tested with two cycles.
- 🐇 ToF read could stall the render task: done, a measured read is now a prerequisite.
- 🐇 G1 inverts modifiers too: done in the plan; the code inverts the whole mapping, so G5 (next commit) inverts the layout's mapping alone, with rotated and mirrored tests.
- Gates: check_prose, check_docgen, check_code and two rate tests failed on the first run (long sentences, over-wide comments, test clones, the rate window against the test clock); fixed and rerun, all below baseline. ESP32 classic, S3 and P4 rebuilt and fresh; the Teensy built and verified on the bench.

Line 119 reports 28 cells with at least four samples, but the scenario table has 29 unmarked cells. This makes the generated coverage summary inconsistent with its table. Regenerate the report and correct the stale measurement or report output. The renderer in moondeck/check/repo_health.py, Lines 705-740, uses the same n >= 4 threshold for the marker and the 4+ count.

A stream mapped by its sender (xLights, FSEQ, Network Send) now reaches the LEDs in one copy on any layout, halving the S3's tick at 64x64, and a modifier on its layer transforms it. A new Picture service and Picture effect show a test card on any layout, fitted, filled or stretched, ready for USB capture and a browser source to feed them. The installer resends settings the board refused, lets a mistyped WiFi password be corrected in place, and applies a device's defaults without reflashing.

Under a static modifier the frame is placed by the layout's positions (Layer::placeByLayout), so a mirror or transpose transforms it. - G6: ChannelDataSink holds, places and copies channel data for Network Receive and the new FseqPlayerEffect, a registered stub with file, loop and speed that reads no file yet (TouchMyLight's contribution). - G4: PictureEffect samples the picture per light, fit, fill or stretch, point or area in linear light, from separable range tables refilled without allocating. - Drivers composites through one composite() helper; BeatRipples walks the whole palette, its index wrapping with height and shifting per stone. **UI** - Installer: stop-and-wait APPLY_OP that reads the board's replies and resends a refused or unanswered document; a WiFi form that comes back with the reason after a failed join; "Apply device defaults now, without flashing"; an erase progress bar estimated at 3 s per MB. - Tooltips for the picture and recorded-show emoji. - Waveshare ESP32-S3-RGB-Matrix device model: ES7210 audio and BeatRipples as its default effect. **Scripts/MoonDeck** - fseq_play: writes and plays uncompressed FSEQ v2 over DDP, the reference sender for FSEQ. - monitor_esp32 raises only the board on its port to Info, in the background, restores it on exit or SIGTERM, and opens the port without asserting DTR/RTS; collect_kpi raises only its own board and says when none is registered. - screenshot_modules lets the device name the modules it adds, which the 15-character name limit refused for long type names. **Tests** - G5: pass-through on serpentine and 3D layouts, a mirror and a transpose on sender-mapped frames, both failing with the placement switched off. - PictureService: the test card's landmarks, the generation, the empty frame, and a writer task racing a reader with two pictures and with one, both reading every picture whole (the one-picture case fails with its lock removed). - PictureEffect: point against area by hand, fit, fill and stretch, a cube, no resampling without a new picture; FseqPlayerEffect: its output path and status; BeatRipples: the palette spread; NetworkModule: the join window and a rejoin after a dropout; installer reply parsing. **Docs/CI** - Streams plan: G3 to G7 built, G8 (the browser as a picture source) added with recording and baking as follow-ups; the how-to for adding a picture or channel-data source (G7); cards and images for Picture, FseqPlayer and the new Network Receive card. - CLAUDE.md: every pull request is based on main, the one exception a step of a larger topic. **Reviews** - 👾 the background log-level raise could hold the port for about 75 s on an unreachable board: fixed, it stops with the monitor. - 👾 collect_kpi skipped a board with no recorded port silently: fixed, it says so. - 👾 wiringSource computed per frame: kept, since a state document that changes mapped_by re-prepares only the effect, so a cached answer would go stale. - 👾 any Improv error aborted the defaults push: fixed, only "unknown RPC" means unsupported, the rest is resent. - 👾 the two-picture writer path has no writer yet: accepted, it is #139's groundwork, built on request before this commit; the double generation bump in prepare fixed. - 👾 FseqPlayerEffect's default dimensions override and PictureEffect's unexplained include: fixed. - 🐇 CLAUDE.md's generated-file wording, the plan's pacing paragraph, a long test comment, an unsynchronized staging read in a test: fixed; the repo-health coverage count: not a defect, marker and summary share the n >= 4 threshold.

- Line 318: Rephrase the sentence beginning with “#138 and #139” so Markdown
does not parse it as an ATX heading; for example, begin with “Pull requests”
before the issue numbers. Keep the sentence’s existing meaning and links.
Review comments at @moondeck/_moondeck_config.py:
- Line 33: Update the reused-port assignment in the discover path so it clears
last_port from every other record in the active network, including carried-over
offline records, before assigning the port to the newly discovered board; keep
device_ips_for_port selecting only the newly assigned board.
Review comments at @moondeck/docs/screenshot_modules.py:
- Around line 344-345: Update the create flow around the `id_` handling so a
retry after an ambiguous `_post` failure first reconciles whether the initial
create succeeded, or uses a stable request identity to prevent creating a second
auto-named module. Ensure the script tracks the created module before proceeding

Review comments at @moondeck/run/fseq_play.py:
- Line 119: Restrict the `--step` argument in the argument parser to values from
1 through 255, matching the one-byte `step_ms` field packed in `HEADER`, so
invalid values are rejected before file writing.
Review comments at @mooninstaller/install-orchestrator.js:
- Around line 186-198: Update the frame retry loop around `replies.next` so
delayed acknowledgements cannot be mistaken for replies to a resent frame:
correlate acknowledgements with frame sequence numbers if the reply payload
exposes them; otherwise clear stale queued replies before each document attempt.
Give committing frames marked `last` a longer acknowledgement wait, and only
return success after the final frame’s own acknowledgement.
Review comments at @src/core/util/JoinWindow.h:
- Line 15: Shorten the JoinWindow description to distinguish the join grace
period for unassociated stations from the address wait for associated stations;
keep the wording concise and limited to this behavior.
Review comments at @src/light/effects/BeatRipplesEffect.h:
- Around line 145-147: Update the arithmetic in `paletteIndex` to use an
explicit, consistent integer type and bound the result with a `0xFF` mask before
converting to `uint8_t`. Preserve the intended modulo-256 behavior for negative
`height` values and limit `stones` to the bits needed for its contribution.
Review comments at @src/light/effects/ChannelDataSink.h:

Explain the changed baseline timing before committing.
The current observation block already contains a 2026-10-14 rerun. Its desktop-macOS measure-baseline p50 changed from 7 µs to 8 µs, but the diff gives no reason for the change. Add the cause before committing this KPI refresh.

Fix the heading-like line at Line 318.
The static analysis hint reports MD018 for this line. The line starts with #138 and #139, so markdownlint parses it as an ATX heading with no space after the hash. The rendered page shows a heading instead of a paragraph. Rephrase the sentence so it does not start with #, or escape the first character.

Clear reused last_port values from offline records.
The discover path can keep the previous board as an offline registry record while assigning the reused port to the newly discovered board. device_ips_for_port does not filter offline records, and [:1] then selects whichever matching record sorts first. The monitor can raise the log level on the wrong board.
Clear last_port from every other record in the active network when assigning a reused port, including carried-over offline records.

Do not retry an auto-named create without reconciliation.
If the server creates a module but the response connection fails, _post retries the request. With no id, the endpoint can assign a second free name. The script tracks only the returned module, so the first module can remain in the device state and affect later captures. Before a create retry, check whether the first create succeeded, or use a stable request identity.

Keep the orphan sweep from deleting existing modules.
The new 15-character prefix can equal a valid user-assigned module name. When that name matches a listed type prefix, the opening sweep deletes the user’s module before capture. Track modules created by this tool instead of treating a type-name prefix as proof of ownership.

Set dirty_ before you release the lock.
write releases lock_ before it stores dirty_ = true. A render copy can run in that gap. The copy takes the lock, stores dirty_ = false, and copies the frame. The writer then stores true again. The next tick copies the same frame a second time. This costs one extra copy and causes no wrong output. Storing dirty_ while the lock is still held makes the ordering explicit.

Make a sampling change redraw the picture.
tick redraws only when the picture size, the picture generation or the layer generation changes. A sampling change touches none of these. With the test pattern, the generation never changes after prepare, so switching between point and area shows nothing until the next resize. This breaks the rule that every setting applies live.

ESP-IDF 6.1 usb_serial_jtag_vfs_use_driver usb_serial_jtag_is_driver_installed official source
💡 Result:
For **ESP-IDF `release/v6.1`**, both APIs exist, but they’re declared in different headers:
- **`usb_serial_jtag_vfs_use_driver()`** is implemented in `usb_serial_jtag_vfs.c`. It switches VFS read/write/flush callbacks to use the USB Serial/JTAG driver; it does **not** install the driver itself. Install the driver first with `usb_serial_jtag_driver_install()`. ([github.com](https://github.com/espressif/esp-idf/blob/release/v6.1/components/esp_driver_usb_serial_jtag/src/usb_serial_jtag_vfs.c))
- **`usb_serial_jtag_is_driver_installed()`** is declared in `driver/usb_serial_jtag.h`; it returns whether the driver is installed. The VFS source also calls it before handling `select()`. ([github.com](https://github.com/espressif/esp-idf/blob/release/v6.1/components/esp_driver_usb_serial_jtag/include/driver/usb_serial_jtag.h))
The VFS source shows the intended sequence: install the driver, check for success, then call `usb_serial_jtag_vfs_use_driver()`. ([github.com](https://github.com/espressif/esp-idf/blob/release/v6.1/components/esp_driver_usb_serial_jtag/src/usb_serial_jtag_vfs.c))

Switch the USB VFS when an installed driver is reused.
When usb_serial_jtag_is_driver_installed() is already true, this branch sets g_jtagReady without calling usb_serial_jtag_vfs_use_driver(). Improv then uses the USB driver while console writes can remain on the direct FIFO path, which can silence the port. Select the driver-backed VFS whenever g_jtagReady is true.

Update the USB serial JTAG initialization flow so that whenever g_jtagReady is
true, including when usb_serial_jtag_is_driver_installed() reports an existing
driver, the driver-backed VFS is selected with usb_serial_jtag_vfs_use_driver().

Describe host worker placement in positive form.
“Core pinning is a no-op” describes what does not happen. State the host behavior instead, such as “The host leaves worker placement to the operating system.”
As per coding guidelines, “Present tense and positive form only, describing what exists rather than what was or what is not.”

Fix the test comment and pin the black fill.
The comment says the effect "leaves the layer alone". In fact tick fills the layer with black (PictureEffect.h Line 58). Because the test reads as documentation, it describes the opposite of the actual behaviour.
Correct the comment. Also assert that a cell is black, so the test pins the fill.

… installer The pre-merge reviews' fixes. A sender-mapped stream that shares its layer is placed by one rule, a Picture effect's sampling change shows at once, and the installer no longer pairs a late acknowledgement with the wrong chunk. The Waveshare model shows BeatRipples alone, and the smoke test checks a provisioned board's network too.

Network streams now arrive whole, and a stream mapped by its sender reaches the LEDs in one copy on any layout. A new Picture service and Picture effect lay the groundwork for video sources, and the FSEQ player has its module. Uploads stream without ever blocking the lights, the Teensy resolves host names and uploads ten times faster, and the web installer handles a wrong WiFi password and late device defaults without a reflash.
