HLS on the P4, scenario percentiles, S3-Zero, and two new effects - #86
Merged
Conversation
A P4 now streams its wall as H.264 over HLS with no desktop in the loop: the chip's own hardware encoder, our own MPEG-TS muxer, and segments served from a PSRAM ring. Small walls are upscaled so they arrive watchable rather than as a postage stamp, and the bitrate is derived from the grid instead of guessed at. Performance: desktop tick 132 us (-10), FPS 7,575 (+533). Flash: esp32p4rev1-eth-wifi 1,972 KB (+84 KB, 48% of its slot), esp32s3-n16r8 1,808 KB (+1 KB), desktop 1,542 KB. Core: - Select options are JSON-escaped (Control.cpp): the panel-card NIC dropdown feeds OS-supplied adapter names into the schema, and one containing a quote made all of /api/state invalid and blanked the UI. - serveHlsFile serves from RAM before falling through to the filesystem, so a platform that keeps segments in memory answers without a disk round trip. Light domain: - HlsDriver runs on the P4 as well as desktop, stating geometry/rate/bitrate through a structured EncoderConfig rather than an ffmpeg command line the P4 would have to parse back out. - scale control: video pixels per light, 0 = auto. One factor for both axes, so the aspect ratio holds and each light stays a square block. Auto lifts a small wall to the encoder's 80-pixel floor; a wall already past it stays 1:1. - The bitrate control is gone. It follows from pixels x fps, and targetFps is the knob a user actually wants for bandwidth. - Frame pacing is a fixed schedule, not a last-sent timestamp: 1000/fps truncates and a late tick used to shift the schedule for good, drifting until players re-buffered. - PanelCardDriver follows the chosen NIC by name across re-enumeration; an index alone could silently move panel output to a different adapter after a hot-plug. - FlyingToasters velocity uses the 16-bit generator: the 8-bit draw clamped the spread at large sprite scales, so big toasters all flew at nearly the same speed. Platform: - platform_esp32_h264.cpp: hardware encode, RGB to YUV420, a 3-slot frame ring and a 12-segment PSRAM ring behind hlsSegment/hlsSegmentRelease. - MpegTs.h: a pure-logic muxer (PAT/PMT, PES, PCR, continuity), host-testable so the wire format is pinned by tests rather than only by watching a TV. - Encoder slots are reserved at start, off the render tick. - CONFIG_DSP_ANSI=y on P4: a documented workaround for a silicon erratum, not a preference. Tests: - unit_MpegTs (11 cases) including the PAT-to-PMT chain, cross-writer continuity, and a guard-band case for a buffer overrun a sanitizer found but the output did not show. - unit_HlsDriver grew to 17: pacing exactness, late-tick recovery, upscaling by whole blocks, and a scaled frame that would overflow int16 before reaching the encoder. - PanelCardDriver: NIC reorder, JSON metacharacters, seam reset. Docs/CI: - The HLS card is a summary again (94 lines to 18), with the depth in a details section and the mechanism in the header. The shipped spec draft is deleted. - repo-health reports capacity, percentage used, and whether each firmware was actually built this run: a carried-forward number read as "no growth" when it meant "not measured". - A write-time prose hook enforces American spelling and no em-dashes, both already in the standards and both broken repeatedly because they are habits rather than decisions. - Desktop packaging builds only the app target, not the test tree. Reviews: - 👾 Reviewer (34 files): heap overrun where a scaled frame overflowed int16 before the encoder check -> widened and rejected first; continuity counters kept their advance for packets a discarded frame never sent -> snapshot and restore; encoderStop freed PSRAM the worker was still writing when stopPinnedTask detached instead of joining -> gated on a real exit, taking the leak-over-use-after-free trade the worker layer already makes. Two minors: the prose hook no longer touches the git index, and the playlist snprintf accumulate is clamped. - 🐇 CodeRabbit (10 findings, post-merge on #85): 6 fixed (JSON escaping, NIC binding, toaster velocity, encoder slot preallocation, a null-pointer range, "Apple Silicon"); 4 skipped with reasons: the sprite coordinate wrap is unreachable (proven exhaustively negative, so clipped), the installer checksum was a prior PO ruling, and two archived plan documents are history rather than current contracts. Upstream: esp-idf#19025 filed for the P4 hardware-loop erratum this branch works around.

In `@docs/history/plans/Plan-20260827` - HLS on ESP32-P4.md:
- Line 1: Apply the no-em-dash documentation style by replacing the em-dash in
the plan title at docs/history/plans/Plan-20260827 - HLS on ESP32-P4.md lines
1-1, the crash description at docs/backlog/backlog-core.md lines 926-927, and
the M5Stack heading at docs/backlog/backlog-light.md line 177 with appropriate
punctuation.
In `@docs/moonmodules/light/drivers.md`:
- Line 203: Update the 512x512 bitrate example in the bitrate explanation to
approximately 800 kbit at the default targetFps of 30, replacing the incorrect 8
Mbit value; leave the 128x128 example and surrounding guidance unchanged.
In `@moondeck/check/hook_prose.py`:
- Around line 71-74: Update the report filtering around `name` and `lines` to
match the repository-relative path rather than the basename, and track the
current report header so indented detail lines are retained only while that
header belongs to the target path. Ensure the early `if not any(...)` check and
resulting message include findings exclusively for the file being processed.
- Around line 50-64: Update the four subprocess.run calls in the hook to pass
check=False explicitly, resolve git and uv through shutil.which and use their
absolute executable paths, and add the -- separator to the git add -N invocation
before path. Preserve the existing list-based argument handling, return-code
checks, and cleanup behavior.
In `@moondeck/check/repo_health.py`:
- Around line 199-202: Update measure_flash to add every successfully measured
entry, including the desktop entry, to MEASURED_THIS_RUN; remove the
desktop-name special case from the downstream Built-status logic so
merge_carry_forward rows are not reported as measured. Use the existing
measurement tracking symbols MEASURED_THIS_RUN, measure_flash, and
merge_carry_forward.
- Around line 473-476: Update the footnote string appended by the L += list
construction so its adjacent string fragments are enclosed in parentheses,
eliminating Ruff ISC004 while preserving the exact rendered text.
In `@src/core/HttpServerModule.cpp`:
- Around line 698-720: Remove the direct platform::hlsSegment and
platform::hlsSegmentRelease calls from the core HTTP serving path in
HttpServerModule, and expose RAM HLS access through a core-neutral callback or
service, or a platform-side adapter. Preserve the existing RAM-first response
behavior and filesystem fallback, including releasing the reserved segment on
every exit.
In `@src/light/drivers/HlsDriver.h`:
- Around line 346-356: Ensure the explicit scale used before startEncoder is
raised to at least the encoder minimum factor calculated by autoScale, while
preserving the configured value when it already meets that floor; apply this in
the scale-selection path rather than changing autoScale itself.
- Around line 207-211: Update the light-count calculation in the HlsDriver
packing path to multiply srcWidth_ and srcHeight_ as size_t before narrowing or
comparing with sourceBuffer_->count(). Ensure the comparison and subsequent
packing use the widened product so large frames such as 640×480 are not
truncated.
In `@src/light/drivers/PanelCardDriver.h`:
- Around line 167-179: When rebuilding interface options in the chosenIf_
handling, reset interfaceSel_ to the explicit capture-only or invalid state
before searching for a matching ifOptions entry, then overwrite it only when
chosenIf_ matches. This prevents a disappeared adapter from reusing a stale
index while preserving the existing match behavior.
In `@src/platform/desktop/platform_desktop.cpp`:
- Around line 2499-2508: Update encoderStart to call stopEncoderProcess() before
calculating or reserving frame slot capacity in encSlots_. Keep the existing
reserve failure handling, and leave the later spawnEncoderProcess flow intact so
its stop call becomes harmless after the previous writer has been joined.
In `@src/platform/esp32/MpegTs.h`:
- Around line 107-113: Update the stuffing calculation in the MPEG-TS
packetization path so the need calculation accounts for the existing adaptLen
before determining additional stuffing; preserve the current minimum stuffing
behavior and ensure a small single-packet keyframe does not spill into an
unnecessary second packet.
In `@src/platform/esp32/platform_config.h`:
- Around line 301-310: Move the W5500 driver explanation from above
hasNamedNetInterfaces to directly above the hasEthW5500 declaration and its
associated `#if`. Leave only the hasNamedNetInterfaces rationale above that
constant, preserving both constants and their existing values.
- Around line 319-327: Constrain the MM_HLS Kconfig symbol at its declaration so
it cannot be enabled unless SOC_H264_SUPPORTED is present, rather than relying
only on its default value. Preserve the platform_config.h hasHls mapping and
ensure non-encoder targets cannot pull in esp_h264 or platform_esp32_h264.cpp.
In `@src/platform/esp32/platform_esp32_h264.cpp`:
- Around line 204-206: Initialize workerExited_ to true, clear it in
encoderStart before spawning the task, and refuse a new start while a previously
detached worker is still alive. Update workerFn so it no longer performs the
initial reset, and preserve the existing cleanup and running-state behavior for
valid starts.
- Around line 103-112: Rename oddLine to a name indicating that it is true for
even zero-based rows, updating its declaration and all uses including the
references around lines 120–121; preserve the existing chroma-selection logic
and inline comment.
- Around line 310-319: Update encoderWrite to reject null data or len == 0
before any slot access or memcpy, returning the contract’s invalid-input failure
result rather than the full-queue drop result. Preserve existing handling for
stopped encoders, dead state, full queues, and valid frames.
- Around line 365-388: In the playlist-building method, clamp the final value of
n to the playlist buffer capacity after the append loop and before assigning
*len, so truncated snprintf results cannot expose bytes beyond the buffer. Also
replace the shared static playlist buffer with per-request storage or otherwise
keep it protected until the caller finishes reading, ensuring concurrent HLS
requests cannot overwrite one another.
- Around line 409-419: In the !CONFIG_MM_HLS branch of platform_esp32_h264.cpp,
complete the mm::platform encoder seam by defining safe no-op/default stubs for
encoderStart, encoderWrite, encoderRunning, and encoderStop, matching the
declarations in platform.h and preserving the existing HLS segment stubs.
In `@src/platform/platform.h`:
- Around line 531-534: Update the HLS video output contract comment near
HlsDriver to remove the “pixel-exact” claim and describe the payload as the
rendered grid after scaling and output correction, while preserving the existing
H.264-over-HLS and hasHls context.
In `@test/unit/light/unit_Effects_golden.cpp`:
- Line 99: Add a one-line explanation to the comment block above the
FlyingToastersEffect golden test stating that launch() now uses next16() instead
of an 8-bit draw for the speed span, changing per-toaster velocities and
intentionally updating the hash.
In `@test/unit/light/unit_MpegTs.cpp`:
- Around line 8-11: Add the direct <cstring> include to unit_MpegTs.cpp so
std::memcmp is declared independently of MpegTs.h.
- Around line 66-101: Extend “The PAT points at the PMT, and the PMT at the
video stream” with an independent CRC-32/MPEG-2 calculation over each PSI
section and compare its result with the four trailing CRC bytes of both PAT and
PMT, avoiding reliance on crc32Mpeg’s implementation. Add coverage for a small
keyframe passed to Writer::writeAccessUnit and assert it occupies exactly one
video TS packet, exercising adaptation-field stuffing.
In `@test/unit/light/unit_PanelCardDriver.cpp`:
- Around line 605-628: Update both the hot-plug case and the metacharacter case
that iterate over driver.controls() to track whether the interface control is
encountered, require that flag after each loop, and keep the existing assertions
unchanged.

Record the reason for the moved golden.
The header of this file states that a moved hash is updated with its reason. The FlyingToastersEffect hash changes here because launch() now samples the speed span with next16() instead of an 8-bit draw, so the per-toaster velocities differ. Add that one-line reason to the comment block above the test case, so a future reader can tell an intended re-blessing from drift.
Based on learnings, "Docs land with the code, not at merge time".

🎯 Functional Correctness | 🔵 Trivial | ⚡ Quick win
Add a test that validates the PAT and PMT section CRC.
The suite walks the PAT to the PMT and reads the elementary-stream descriptor, but no test checks the CRC-32/MPEG-2 that closes each PSI section. A player that validates the CRC drops the table and reports no video track, which is the same class of failure the comment on lines 63-65 records for the PAT pointer. crc32Mpeg is a hand-rolled implementation, so its polynomial, initial value and bit order need a pinned expected value rather than only internal consistency.
Two checks cover it: recompute the CRC over the section bytes with an independent implementation in the test, and compare it against the four trailing bytes of each table packet.
A second gap: no test exercises a keyframe small enough to fit in one TS packet. That case is where the stuffing arithmetic in writeAccessUnit decides how much adaptation-field padding to add. A test asserting the frame occupies exactly one video packet would pin it.

Assert that the interface control was found.
Both new cases put their assertions inside a loop over driver.controls(). If the interface control is absent, the loop body never runs and the case passes without checking anything. Record a found flag and require it, so a control rename or a platform gate makes the test fail instead of going silent.

In `@test/unit/light/unit_PanelCardDriver.cpp` around lines 605 - 628, Update both

Scenario timing was recorded as a widen-only [min, max] range, so the max converged on the worst thing that ever happened on any machine rather than on what the code costs. One contended run pushed a step from 156 to 2131 us permanently. Observations now keep a rolling window of the last 32 samples and report p50, p95, min, max and n over it: the median is what a step normally costs, p95 is its tail, and neither moves far because one run was unlucky. Scripts/MoonDeck: - _observed.py keeps the window and derives the statistics. Percentiles are nearest-rank, so every reported number is an actual observed sample rather than an interpolation between two that never happened. - The mean and standard deviation were considered and rejected: tick times are a hard floor plus a one-sided tail, closer to log-normal than normal, so the mean is dragged by contention and "outside 1 or 2 sigma" has no stable meaning on that shape. - `at` ([first_seen, last_updated]) becomes `last_updated`, a single date. After a full window the creation date describes samples that have aged out, so it read as "how old is this data" while answering something else. - Migrating an old range seeds the window from its MIN only. The max of a widen-only range is the defect being removed; importing it would hold p95 up for 32 runs. - 42 blocks whose tick was 0 (below the host clock, or never measured) reset to n=0, the same state a target that cannot run here gets. A zero is not a measurement and would drag the median to zero. - generate_test_docs.py reads the shape through one adapter instead of each cell renderer re-deriving it, and renders p50 to p95 rather than min to max, which spanned one lucky run to the worst excursion ever seen. Both older shapes still render. - Sample windows are written on one line: 32 numbers over 32 lines buried the statistics they belong to. Tests: - 23 scenario files migrated to the new shape. Trade accepted: a measured scenario file is now rewritten on every run, where an in-bounds value used to be a no-op. A statistic over a window can only exist if the window survives, and the range that never narrowed was the actual defect.
A new thumbnail-sized board runs projectMM: the ESP32-S3-Zero, 4 MB flash and 2 MB
PSRAM, flashed and bench-verified with its onboard LED lit and a strip header ready.
The 16 MB classic moves to MoonBase as well, trading a second app slot nobody used
between updates for 4 MB more filesystem.
Performance: desktop tick 180 us, FPS 5,555. The delta against the previous 132 us is
measurement noise, not a regression: nothing here touches the render path, and the KPI
run shared the machine with six firmware builds. Flash: esp32s3-zero 1,747 KB (70% of
its slot), esp32-16mb 1,767 KB (+93 KB, the MoonBase table rather than code growth),
esp32 1,767 KB (+10 KB), esp32p4rev1-eth-wifi and esp32s3-n16r8 unchanged.
Core:
- A Select persisted by label matches on the part before ", " when the whole string does
not. An option may carry a live detail there (the NIC list appends a link speed), and
matching the whole label lost the user's pick the moment a link renegotiated.
Light domain:
- HlsDriver packs its light count in size_t: nrOfLightsType is uint16_t on a board
without PSRAM, so a 640x480 grid truncated to its low 16 bits.
- An explicit scale is raised to the encoder's minimum only where the hardware has one.
A desktop ffmpeg does not, so a small 1:1 stream stays exactly that.
- PanelCardDriver drops to capture-only before re-matching its NIC: an adapter that
disappeared left the selection on whatever took its row, sending panel data out of a
NIC the user never chose.
Platform:
- New esp32s3-zero variant. Neither existing S3 image can boot this board: both assume
8/16 MB flash and set SPIRAM_MODE_OCT, and octal mode fails PSRAM init on its quad
part. On the MoonBase layout, so the app has 749 KB of headroom rather than 48.
- MoonBase builds for a chip with no internal EMAC. It had only ever been built for the
classic ESP32 and called esp_eth_mac_new_esp32 unconditionally, which does not exist
on the S3; guarded on SOC_EMAC_SUPPORTED, it falls back to WiFi, the right recovery
path on a board with no Ethernet. This unblocks MoonBase on any WiFi-only chip.
- esp32-16mb on MoonBase: one 4096 KB app slot, filesystem 7168 to 11264 KB. The second
slot sat idle except during an update, and MoonBase covers that with a stronger
power-fail story.
- The interface list shows each adapter's link speed ("Realtek PCIe GbE, 1 Gb"), since
the name alone does not say which entry is the 1 Gb NIC and which a virtual switch.
Per-OS lookup (MIB_IF_TABLE2, sysfs, SIOCGIFMEDIA), one shared formatter.
- P4 encoder: encoderWrite rejects null input, the playlist length is clamped to its
buffer, the no-HLS build gets the whole seam rather than half of it, and a chroma flag
named oddLine is renamed for the even rows it actually marks.
Tests:
- A new partition table must declare its capacity (unit_PartitionTables caught the 16 MB
MoonBase table immediately, which is the point of that list).
- PanelCardDriver: a NIC whose speed changed, and one that disappeared.
Docs/CI:
- MoonBase is documented as a per-variant choice rather than a 4 MB rule. It now covers
the 4 MB classic, the S3-Zero and esp32-16mb, and may become the default.
- MIGRATING: esp32-16mb repartitions, so it needs an erase-flash and a backup first.
- deviceModels.json gains the S3-Zero with its pinout image, the onboard LED on GPIO 21
capped to one light, and a strip driver on GPIO 2.
- repo-health reports whether each firmware was actually built this run. It immediately
caught that cmake writes build/projectMM while repo-health reads build/macos/projectMM,
which had been reporting a stale desktop number as a measurement.
- CLAUDE.md: never revert without asking. A written statement is a status, not a law, and
only the product owner knows which.
Reviews:
- 🐇 CodeRabbit (16 findings on the previous commit): 11 fixed, including a 10x error in
the documented bitrate example (512x512 is ~786 kbit, not 8 Mbit, wrong in both the card
and the header) and the light-count overflow above. 5 skipped: em-dashes in docs/history
and docs/backlog (both exempt in check_prose), an indirection for hlsSegment that would
add an abstraction for one caller, an MpegTs stuffing change whose spill does not
reproduce against the ffmpeg-validated tests, a Kconfig guard against a hand-edit nobody
makes, and a second CRC implementation weaker than the ffprobe validation already run.
- The scale-floor fix was applied differently from the suggestion: as written it broke
four tests, because only the P4 hardware has an 80-pixel minimum and forcing it on
desktop would refuse streams ffmpeg handles.

Two new effects join the sprite family: an aquarium of palette-colored fish, and the Pacman cast chomping its way across the wall. All three sprite effects (including Flying Toasters) gain a soundReactive checkbox: each sprite rides its own frequency band, so a kick moves the bass sprites while the hi-hats move the treble ones, and silence stands the scene still. Performance (desktop, no board attached so ESP32 targets are not measured): KPI: 16384lights | Desktop:1542KB | tick:8376us(FPS:119) | heap:134KB | src:234(66326) | test:176(40054) Light domain: - FishTankEffect: three fish shapes swimming both ways through one mirrored drawing; the art carries shade ROLES rather than fixed colors, so each fish fills them from its own place on the palette and one drawing yields as many colorways as there are fish. - PacmanEffect (iteration 1): Pacman plus four ghosts crossing the wall and wrapping the edges, not yet noticing each other. One ghost drawing serves all four colors via palette slots. The maze, pellets and chase are iteration 2, built on the shapes and movement grid this establishes. - soundReactive on FishTank, Pacman and FlyingToasters, sharing one rule. Core: - particles::audioDrive(): per-sprite audio speed from the sprite's own FFT band, gated on the overall level so silence freezes the scene. Returns normal speed when there is no audio source, so a device with no microphone never freezes. - particles::Pool::stepEach(): step() with a per-particle time scale, which is what lets the sprites move independently instead of as one block. - particles::spreadLane(): maps slot i onto a distinct lane, stepping by a value chosen coprime with the count. Fixes a real bug: `(i * 5) % 5` is zero for every i, which stacked all five Pacman characters on one row. FishTank carried the same latent bug for counts divisible by 5 or 7. - draw::sprite() gains flipX, mirroring the read so one drawing serves both travel directions. Scripts/MoonDeck: - Scenario observations no longer record all-zero free_heap / max_alloc_block blocks: on desktop those are a constant 0 that never changes. 0 all-zero blocks remain; the 630 blocks of real ESP32 measurements are untouched. Tests: - Lane distinctness across every count, the silence rule, the no-audio-source rule, and the per-band divergence that keeps the scene from surging as a block. - Golden frame for PacmanEffect; FishTankEffect's golden re-pinned after visually confirming the new lane spread renders correctly. Docs/CI: - Pacman catalog card; soundReactive documented on all three effect cards. Reviews: - CodeRabbit on PR #85: 5 findings fixed (HLS resync duplicate frame, P4 odd dimensions, FPS range with a zero endpoint, sizing docs, MoonBase variant list in building.md), 2 skipped as no longer valid against current code. Verified: 1542 test cases / 102589 assertions pass, check_prose and check_specs clean, and the sound-reactive path confirmed by the product owner playing music against the running desktop build.

Reassign live slots when population boundaries change.
Both effects update slot liveness without reinitializing surviving slots whose role or species has changed. In PacmanEffect, changing pacmen from 1 to 2 while ghosts changes from 4 to 3 can leave the old assignments because alive == want. In FishTankEffect, changing fish from 3 to 0 leaves existing broad fish active until they leave the screen.
After trimming and topping up, derive the required role or species for each active slot and relaunch any slot whose stored assignment differs.

Use an interleaving stride and verify every pair.
For slots == 8, the selected stride is 7. The lane order becomes 0, 7, 6, 5, 4, 3, 2, 1, so most consecutive slots remain adjacent. This groups adjacent species or roles instead of interleaving them.
src/light/particles.h#L147-L155: select a coprime stride near half the slot count, such as3or5for eight slots.test/unit/light/unit_Particles.cpp#L703-L713: require every applicable consecutive pair to be non-adjacent. Do not accept one non-adjacent pair.
As per path instructions, test/** must verify edge cases.

Detect every encoded frame in one tick.
Lines 447-448 add one timestamp when the frame count changes. If one driver.tick() encodes two or more catch-up frames, the test records only one timestamp. The 100 ms interval check then passes despite the burst that this test must reject.
Record one entry per increment, or assert that the frame count increases by at most one per tick.

The pre-merge review round. soundReactive only ever drove the bass end of the spectrum, changing a sprite count left the wall showing the old cast, and the encoder could resize buffers a live writer was still reading. All found by review, all reproduced before being fixed. Performance (desktop, no board attached so ESP32 targets are not measured): KPI: 16384lights | Desktop:1542KB | tick:8376us(FPS:119) | heap:134KB Light domain: - soundReactive spread the 16 FFT bands over the pool CAPACITY rather than the live sprite count, so five characters in a pool of twelve all sat on bass-adjacent bands and the treble drove nothing. The mode still visibly moved, which is why playing music did not reveal it. - Changing how many of each kind are on the wall left the live slots holding their old roles: trading ghosts for Pacmen keeps the total unchanged, so nothing respawned and the controls said three Pacmen while one was drawn. Fixed in Pacman and Fish Tank via a single roleFor/speciesFor rule. - particles::stepDriven(): the soundReactive branch was byte-identical in all three sprite effects. One home for the rule, one line in each effect, and the band-spread fix lands in one place instead of three. - spreadLane picks a stride coprime with the count AND near half of it. Coprimality alone only makes the lanes distinct: slots-1 is coprime but congruent to -1, so consecutive slots walked DOWN adjacent lanes and nothing was interleaved. Minimum gaps go from 1 to 2/3/5/11. - The three sprite effects carry the audio tag now that they read the spectrum. Fish Tank's WLED origin tag was wrong: it is a projectMM original. Core: - MpegTs.h moves from src/platform/esp32/ to src/light/. It is platform-neutral byte-layout logic (no esp_*, namespace mm::ts) and its host test was reaching across the platform boundary to include it. - The HLS RAM branch writes the body in one call instead of a 1 KB loop copied from streamFsFile: conn.write already sends all bytes, so chunking a resident buffer only gave each piece a fresh deadline. The header snprintf is guarded. Platform: - Desktop encoderStart resized the frame slots while the previous writer thread was still reading one without the mutex; a scale change reallocates and frees that buffer mid-write. It stops before resizing. - A detached P4 encode worker could resurrect: stopPinnedTask detaches after its join deadline, and the next start set running_ back to true, giving two producers on one encoder handle. Workers are retired by generation. - workerExited_ was cleared inside the worker, so a stop landing between the spawn and the worker's first instruction freed buffers under a live worker. - A segment could open on a non-keyframe after an overflow rotate, leaving a seeking player with no reference frame. The comment claimed otherwise. - MM_HLS depends on IDF_TARGET_ESP32P4. The title said P4-only but nothing enforced it, so a fragment could pull esp_h264 onto silicon with no encoder. Tests: - unit_SpritePopulation pins the role fix through the drawn frame (Pacman's yellow belongs to no other character, so counting it counts Pacmen). - The interleave test now checks EVERY consecutive pair across counts 5-12; the old form passed if merely one pair was non-adjacent, which is exactly why it never caught the stride. - The HLS pacing test asserts at most one frame per tick, so a catch-up burst cannot slip past the interval check. - Goldens re-pinned for both effects after visually confirming the new spread. Docs/CI: - Effect cards carry the new tags; soundReactive documented on all three. Reviews: - 👾 Reviewer over the branch diff: 11 findings fixed, 4 skipped with reasons. - 🐇 CodeRabbit: all 29 inline comments verified against current code, 26 fixed, 3 skipped. Core calling platform::hlsSegment is the platform seam working as intended (core already makes 96 such calls); the syncPopulation ordering claim does not hold; the tag legend drift is real but pre-existing and library-wide. Verified: 1545 test cases / 103961 assertions, every mechanical merge gate green, and all four bench boards (classic, S3-N16R8, S31, P4) built, flashed and booted. The performance snapshot in performance.md is not updated: the desktop KPI above is recorded, but no board was attached to measure the ESP32 targets.

Four pieces of work on one branch: HLS streaming from the ESP32-P4 in hardware, a rework of how scenario observations are recorded, ESP32-S3-Zero support with MoonBase on the 16 MB classic, and two new effects (Fish Tank and Pacman) that brought a shared sound-reactive mode to the sprite effects.
Bench-verified across four boards: classic ESP32, S3-N16R8, S31 and P4 all build, flash, boot and run this branch. The P4 streams 128x128 upscaled to 384x384: VLC plays it, ffmpeg records 300 frames in 10.0 s with no corrupt packets. The sound-reactive mode was verified against real music on the desktop build.
Performance: desktop tick 132 us (-10), FPS 7,575 (+533).

A P4 streams its wall as H.264 over HLS with no desktop in the loop: the chip's own hardware encoder, our own MPEG-TS muxer, and segments served from a PSRAM ring. Small walls are upscaled so they arrive watchable rather than as a postage stamp, and the bitrate is derived from the grid instead of guessed at.

§ HLS, detailssection and the mechanism in the header. The shipped spec draft is deleted.repo-healthreports capacity, percentage used, and whether each firmware was actually built this run: a carried-forward number read as "no growth" when it meant "not measured".2. Scenario observations: percentiles over a sample window
tick_uswas a widen-only[min, max]range, so one contended gate run poisoned a baseline permanently (a 156 us scenario recorded 2131 us and stayed there). Observations are now p50/p95/min/max/n over a rolling 32-sample window, which absorbs an outlier instead of enshrining it.Zero values are never recorded: on desktop
free_heapandmax_alloc_blockare a constant 0 meaning "unlimited", and storing a field that never changes is noise. Verified after the change: 0 all-zero blocks remain, and the 630 blocks of real ESP32 measurements are untouched.3. ESP32-S3-Zero, and MoonBase on the 16 MB classic

Two new effects, plus a shared sound-reactive mode across all three sprite effects.
soundReactiveon Fish Tank, Pacman and Flying Toasters, shared asparticles::audioDrive()+Pool::stepDriven(): each sprite rides its own FFT band, so a kick moves the bass sprites while hi-hats move the treble ones, and silence stands the scene still.

Coprimality alone only guarantees distinctness;slots - 1is coprime but congruent to -1, so consecutive slots landed on adjacent lanes and nothing was actually interleaved.MpegTs.hmoved fromsrc/platform/esp32/tosrc/light/: it is platform-neutral byte-layout logic (noesp_*, namespacemm::ts), and its host test was reaching across the platform boundary to reach it.Reviews
👾 Reviewer (34 files): three majors, all fixed:
int16before the encoder check. An 821×4 wall at scale 80 wrapped to 144×320, so the buffer was sized from the wrapped number while the pixel loop walked the real source. Now widened and rejected first.encoderStopfreed PSRAM the worker was still writing, becausestopPinnedTaskdetaches rather than joins after its deadline. Now gated on a real exit, taking the leak-over-use-after-free trade the worker layer already makes.Two minors also fixed: the prose hook no longer touches the git index, and the playlist
snprintfaccumulate is clamped.🐇 CodeRabbit (10 findings, post-merge on #85): 6 fixed, 4 skipped with reasons:
👾 Reviewer + 🐇 CodeRabbit, pre-merge round over the whole branch - 11 fixed, 4 skipped with reasons:
Defects found and fixed:
soundReactiveused only the bottom third of the spectrum. The band spread was taken over the pool CAPACITY rather than the live sprite count, so with 5 characters in a pool of 12 every sprite sat on a bass-adjacent band and the treble drove nothing. The feature worked visibly, which is why it passed a listening test.encoderStartresized the frame slots while the previous writer thread was still reading one without the mutex; ascalechange reallocates and frees the buffer mid-write(). Now stops before resizing.stopPinnedTaskdetaches after its deadline and the next start setrunning_back to true. Now retired by generation.workerExited_was cleared inside the worker, so a stop landing between the spawn and the worker's first instruction freed buffers under a live worker. Now cleared at start.MM_HLSwas not constrained to the P4 - the title said "P4 only" but a fragment could enable it on silicon with no encoder. Verified both directions after the fix.snprintfguard and a copied chunk loop in the RAM serving path, effect tags, and two weak tests strengthened (the interleave test passed if merely ONE pair was non-adjacent, which is why it never caught the stride).Skipped: core calling
platform::hlsSegmentis the platform seam working as intended (core already makes 96 such calls, andfsReadAtsits beside it); thesyncPopulationordering claim does not hold; the📊/🔊tag legend drift is real but pre-existing and library-wide; modulo bias in the toaster draw is under 5% and cosmetic.Upstream
esp-idf#19025 filed for the ESP32-P4 hardware-loop erratum this branch works around: IDF patches it on the coprocessor restore paths but not on save, so a task switched out of the esp-dsp assembly FFT loses its loop state and faults. Another reporter hit the same fault independently (esp-dsp#119), on a different IDF version.
