Conversation
The FUG-60 flasher rides on the Web Serial API, which Chrome exposes on desktop but not on Android — so the port chooser found nothing and the Device tab's flash flow was a dead end on phones/tablets. Android Chrome does expose WebUSB, so install Google's web-serial-polyfill (a Web Serial implementation over WebUSB, the same layer esp-web-tools / esptool-js#144 use) as navigator.serial when native Serial is absent but WebUSB is present. The polyfill's ports implement the standard SerialPort interface (getInfo/readable/writable/open/close/setSignals), so esptool-js and every flash backend are unchanged — the exact same detect → write → hard-reset path now runs over WebUSB. - webserial.ts snapshots the browser's real capabilities first (installing the polyfill makes `"serial" in navigator` true, which would otherwise mask the WebUSB fallback in diagnostics), then installs the polyfill. - env.ts: WebUSB now counts as a flashable transport (with an Android caveat note); only a browser with neither API (e.g. iOS) is reported as unsupported. Adds a "Flash transport" diagnostics line. - flashSheet.ts: updated help copy and surfaces the WebUSB caveat up front. - The polyfill lands only in the lazy flashSheet chunk, off the main bundle. Deps: web-serial-polyfill (Apache-2.0) + @types/w3c-web-usb, wired into the web BUILD target. Tests: extended flashEnv suite (Android-ok-via-polyfill, iOS-unsupported), full //web:unit_tests (50) and typecheck pass, and the Vite bundle builds. End-to-end Android write needs a real board + Android Chrome, unavailable in the container — flagged for manual verification, as with FUG-60's desktop path.

…-USB baud)
Flashing from Android Chrome failed at three successive points; this makes the
whole detect -> write -> verify path work on the ESP32-C6's native USB.
1. Install the polyfill even when navigator.serial exists. Chrome for Android
138 shipped Web Serial, but only over Bluetooth (it can't see a USB board),
so the native picker listed phones/speakers and never the ESP. Install the
WebUSB polyfill whenever WebUSB is present AND (no native Serial OR Android).
navigator.serial is a read-only accessor once native, so assigning to it
throws in module code (and, running at import, took down the flashSheet
chunk -> button did nothing); install via Object.defineProperty instead, in
a try/catch, and surface "WebUSB polyfill installed: yes/no" in diagnostics.
2. Patch web-serial-polyfill's empty-chunk enqueue. The C6's USB-Serial/JTAG
emits zero-length USB packets; the polyfill enqueued them into a byte stream,
which throws "chunk is empty" and kills the read loop ("No serial data
received"). pnpm patch guards the enqueue on byteLength > 0.
3. Skip the baud-change reopen on native USB. esptool-js renegotiates baud by
closing and reopening the port; the C6's native USB-Serial/JTAG goes silent
after re-claiming its interface mid-flash, and its baud is nominal anyway
(USB runs full-speed regardless). Keep native-USB (VID 0x303a) at 115200 to
skip the reopen; real UART bridges still get 921600.
Tests: extended flashEnv suite (Android-with-native-Serial routes via polyfill),
full //web:unit_tests (51) + typecheck pass, Vite bundle builds with the patched
polyfill and the native-USB baud path. On-device Android write confirmed working.

Renaming a device regenerates its self-signed TLS cert (its CN/hostname is derived from the name, FUG-83) and reboots it to apply the new identity. The already-connected client saw a warm drop and reconnected with backoff — but every reconnect now hit the NEW, untrusted cert (ERR_CERT_AUTHORITY_INVALID) and closed without welcoming. Because the client had already welcomed once, the cert-trust give-up path (gated on !everWelcomed) never fired, so it retried forever, stuck at "connecting (N)…" with no way for the user to re-trust the cert. Track consecutive reconnects that never reach welcome (reset on each welcome) and, on a cert-trust target, surface onCertTrustNeeded once they exceed a limit — for a warm client too, not just a cold one. The cold limit stays 1 (an untrusted cert is untrusted from the first attempt); the new warmRetryLimit defaults to 4 so an ordinary reboot (same cert) still reconnects within the backoff instead of prematurely dropping the user to "trust needed". Once surfaced, the existing "Trust & connect" flow re-accepts the rotated cert and reconnects. Test: warm wss client whose reconnects keep failing surfaces cert-trust after warmRetryLimit and then stops; existing cold-give-up test unchanged. Full //web:unit_tests (51) + typecheck pass.

…S restart) Renaming a device left wss:443 dead until reboot. Device serial at the rename: [wss] re-issued cert with SAN IP:192.168.68.50 (heap=78800); restarting TLS [wss] httpd_ssl_start failed: 45064 (heap=77620) 45064 = 0xB008 = ESP_ERR_HTTPD_TASK: httpd_ssl_start's xTaskCreate for the 28 KB server-task stack (cfg.httpd.stack_size) failed — NOT for lack of heap (77 KB free) but for lack of a CONTIGUOUS 28 KB block. The heap is fragmented by the TLS handshakes that ran while the browser rejected the untrusted self-signed cert (min-free fell to 14 KB), and reissue_cert_for_lan() tore the server down and immediately restarted it. Two firmware bugs compounded it: 1. The rename forced the re-issue at all. The STA IP — the SAN the app connects by — didn't change; only the hostname (cert CN + <hostname>.local DNS SAN) did. So the served cert stayed valid and the restart was pure downside: it both risked the 0xb008 wedge AND rotated the cert bytes, forcing the browser to re-accept the self-signed cert. Fix: poll_device_rename no longer zeroes g_cert_ip. The hostname lands in the SAN on the next genuine IP change/reboot (all the DNS SAN is used for); wss stays up AND trusted across a rename, and the app's socket never even drops. 2. The unavoidable restarts (real IP change) weren't robust. httpd_ssl_stop()'s 28 KB task stack is reclaimed by the idle task asynchronously, so an immediate wss_start() races the reclaim and hits 0xb008. And g_cert_ip was committed BEFORE the restart, so a failed one was never retried. Fix: yield after httpd_ssl_stop() so the idle task frees the stack (reopening the hole the new task reuses), and commit g_cert_ip only on a confirmed restart so a failure self-heals via loop()'s reconcile instead of stranding :443. Complements the web-side warm-drop cert-trust fallback (prior commit): with (1) a rename needs no re-trust at all, and the fallback covers genuine cert changes. Builds: bazel build //firmware/player_app:esp32c6_flashbundle. Hardware verify on lilbuddy pending (HITL bench couldn't hold a DUT on WiFi this session).

Reserve -> flash -> Improv-provision -> connect wss -> rename via set_device_name -> probe that :443 stays up. This is the on-hardware regression for the rename wss wedge (httpd_ssl_start ESP_ERR_HTTPD_TASK 0xb008 on the cert-reissue restart, fixed in the firmware commit). With --device-ws it hits a reachable board directly (skipping reserve/flash/provision) — how it was used to verify the fix against lilbuddy: initial connect + rename + reconnect all succeed, vs the prior permanent ConnectionResetError. py_binary mirrors the other harness on-hardware drivers (manual + hitl tags).

…in //... Two lanes were crossed. Fix both: - The on-hardware workflow (was `HITL e2e`, job `hitl-e2e`) ran only the e2e binary. Rename it to `HITL tests` / job `hitl_tests` and run the WHOLE //pi/hitl/harness on-hardware suite — e2e, map_upload, mapping_trigger, fx_bench, rename_wss — each grouped in the log so a failure names the target. Every binary takes --server; e2e keeps its --monitor-seconds/--skip-flash knobs. The concurrency group already serializes the bench, so runs are sequential. - The pure-logic units (//pi/hitl/tests:hitl_test — Improv codec + SNTP sync, no hardware/network) were tags=["manual","hitl"] and run by a bespoke `hitl-tests` job in test.yaml that bazel-queried the `hitl` tag. Drop the tags so they run in the normal `bazel test //...` suite (the `test` job) like every other unit test, and delete the now-redundant job. The harness py_library has no pip deps and the test imports none of the BLE/ws modules, so //... stays light.

…azel test` The on-hardware harness drivers were py_binaries the workflow `bazel run` one by one. Make them the real test surface instead: convert e2e, mapping_trigger, fx_bench, map_upload, and rename_wss to py_test tagged ["manual","hitl"] (timeout=eternal — a flash+provision cycle runs minutes), and have hitl.yaml discover them the same way the unit lane used to — `bazel query 'attr(tags, "\bhitl\b", tests(//...))'` — then `bazel test` the set. `manual` keeps them out of `bazel test //...` (the normal lane, where the pure-logic units now live); the `hitl` tag is now unambiguously "on-hardware", so the query returns exactly these five. Run with --test_output=streamed so the shared bench takes one reservation at a time with live flash output; HITL_* env is forwarded with --test_env and a pinned --server via --test_arg (all targets accept it). Each is still `bazel run`-able locally (e.g. --device-ws). Verified: the query returns the five; they build as tests and are excluded from the non-manual //... wildcard while //pi/hitl/tests:hitl_test stays in it.

…dled) Now that the firmware keeps wss up across a rename (no reconnect), the device echoes a fresh `welcome` as the set_device_name REPLY on the LIVE socket. The client's onmessage handler treated ANY `welcome` as the initial handshake: it re-fired onConnected — which sets the pill to "syncing clock…" — and returned before dispatching, so setDeviceName's `welcome` waiter never resolved. Nothing follows an already-connected re-welcome with a syncClock + "connected" (that only happens in the initial connect() chain), so the pill hung at "syncing clock…" even though the socket was fine. Only the FIRST welcome on a socket is the handshake (fires onConnected, resolves connect()). A later welcome is a request reply: update the cached welcome and dispatch it to the waiter so setDeviceName/setColorCorrection resolve, without re-running the connect path. The device sheet's applyWelcome + "Device renamed" toast now fire too. Test: a re-welcome resolves setDeviceName with the new deviceName, does NOT re-fire onConnected, and stays connected.

The per-device row had a one-tap trash (Forget) button sitting next to Connect, and the config popup was only reachable by long-press/right-click — undiscoverable and easy to fat-finger the delete. Replace both with a single 3-dots (⋮, the `more` icon) button that opens the existing device config popup. Delete already lives in that popup as "Forget device", so it stays one layer down where it can't be hit by accident, and the config is now an obvious tap rather than a hidden long-press. Drops the pointer/contextmenu long-press handlers. Typecheck passes. Co-Authored-By: Claude Agent <k4757026@gmail.com> Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
…onnect Three devices-page tweaks: - Probe immediately on disconnect. The prober skips the ACTIVE device (it's connected), so after a disconnect the just-freed device kept a stale dot until the round-robin/backoff loop happened to reach it (up to a full interval). disconnect() now calls deviceProber.probeNow(id) so the row flips to reachable/offline right away. Factored the per-device probe into probeOne(); probeNow()/probeAllNow() reuse it, bypassing the round-robin. - Pull-to-refresh. Dragging the devices list down past a threshold fires a one-shot poll of every non-active device (deviceProber.probeAllNow()), with an in-place "Pull / Release / Refreshing…" indicator between the head and the list. Touch-only; desktop still gets the auto-poll + refresh()-on-open. - Connect/disconnect as plug icons. Connect is a plug on --accent (blue), disconnect a slashed plug on --err (red) — clearer and more compact than the text buttons. Adds `plug`/`plug-off` icons and a `className` hook on IconButton. Typecheck + //web:unit_tests (51) pass; Vite bundle builds with the new icons/CSS.

appState.connect() marks the device active immediately, so the row's button flipped straight to the red disconnect while the wss handshake was still in flight. Split the active state: only isConnected (welcome received) shows the red disconnect; active-but-not-yet-connected shows a new gray "connecting" plug that breathes (plug-pulse) with a slash "wave" sweeping across (plug-slash-wave), and tapping it cancels the attempt. It settles to red once the handshake completes. Honors prefers-reduced-motion (drops the animation). Typecheck + Vite build pass.

…inner Two refinements to the previous commit: - The connecting plug now also covers the "syncing clock…" phase. Red disconnect shows only in the fully "connected" status state; "connecting…" and "syncing clock…" both report state "connecting", so both keep the gray in-progress plug. And the animation no longer restarts on the sheet's per-status-change re-renders: the recreated button is phase-synced to a global 1.2s clock via a negative animation-delay (--conn-phase, set from performance.now()), so pulse + slash-wave stay continuous. The status dot also now tracks status.state directly while active. - Pull-to-refresh uses a spinner instead of text: it rides the fold's bottom edge and fades in as you pull (frozen), starts spinning on release past the threshold, and pops out (scale/fade) when the poll resolves before collapsing. prefers-reduced-motion drops the spin/pop. Typecheck + Vite build pass. Co-Authored-By: Claude Agent <k4757026@gmail.com> Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Reworked the device detail sheet: - Display name shows as a label with a pencil (edit) button; tapping swaps in an input with a floppy (save) button. Enter/floppy saves, Escape or tapping away cancels (the floppy's pointerdown is prevented so the input's blur=cancel doesn't beat the save click). Drops the big full-width "Save name" button. - Color correction / Move to folder / Forget are now a compact ActionGrid (icon over label, same tiles as the map/effect browsers) instead of three full-width buttons; Forget keeps the danger tint. - Reordered: display name → action grid → divider → diagnostics (LAN address, MAC, folder). Dropped the redundant "Bluetooth name" row (it's the display name). Adds a `save` (floppy) icon. Typecheck + //web:unit_tests (50) + Vite build pass. Co-Authored-By: Claude Agent <k4757026@gmail.com> Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Trim the ActionGrid tiles to single words — "Gamma", "Move", "Forget" — so the labels fit the tile face, and swap the color-correction tile's sparkles glyph for a new `gamma` icon: an exponential curve plotted on axes. Typecheck + Vite build pass. Co-Authored-By: Claude Agent <k4757026@gmail.com> Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
The inline name editor jumped the content below it when switching modes: the <input> is taller than the label span, and .sheet-input carries a margin-bottom that only appeared in edit mode. Give the label span the same box as the input (equal padding, a transparent 1px border, matching line-height) and zero the input's margin, so the row height is identical in both states and the pencil/floppy stays vertically centered. Vite build passes. Co-Authored-By: Claude Agent <k4757026@gmail.com> Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
The prior fix didn't take: .device-name-input and .sheet-input have equal specificity and .sheet-input is defined later, so its margin-bottom (present only in edit mode) and `font: inherit` (resetting line-height) won — the row still grew/shifted on edit. Bump the selector to `input.device-name-input` (type + class) so the margin-zero + matched line-height actually apply, keeping the row a constant height across the toggle. Vite build passes.

The connected-device subtitle showed clock.offsetMs, e.g. "offset 6955340.1ms". That offset is "add to local time to get server time" = the device's millis() since boot minus the tab's performance.now() since load — two unrelated monotonic epochs, so the number is huge (hours in ms) and reads like a fault, though it's just an internal mapping used for pattern-clock scheduling. Show the round-trip latency (the kept min-RTT sample) instead — small and an actual link-quality readout — e.g. "connected · 12 ms RTT"; falls back to no suffix until the first sync lands (rtt starts Infinity). Typecheck + Vite build pass. Co-Authored-By: Claude Agent <k4757026@gmail.com> Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
The dev container reaches the tailnet but its DUTs drop WiFi, so the on-hardware
harness is flaky there; on a laptop that's properly on the tailnet the tests run
to completion. This shim runs on such a host and is curl-driven, so the suite can
be exercised one target at a time from anywhere:
python3 pi/hitl/scripts/hitl_shim.py # or bazel run //pi/hitl/scripts:hitl_shim
curl -N http://<host>:8091/run?target=e2e
curl -N http://<host>:8091/runall
Each /run shells out to `bazel run -c opt //pi/hitl/harness:<target> -- <args>`
in the checkout and streams combined output + the exit code. Some targets don't
complete bare (fx_bench's --out is required; the wss ones want --insecure), so
each carries a default arg set, overridable per request (?args replaces, ?extra
appends, ?server adds --server). One run at a time; the bench is shared. Stdlib
only; modeled on tools/flash_server.py. Smoke-tested (usage/validation/errors).

… out
Two things from running the suite on a real rig via hitl_shim.
1) Default all wss tests to accepting the device's self-signed cert. e2e already
modeled `--ws-verify` (verify = opt-in); map_upload, mapping_trigger, fx_bench,
and rename_wss carried `--insecure` (two even defaulting False, so they FAILED
the self-signed bench cert bare). Swap each for `--ws-verify` and derive
`insecure = not ws_verify`, so every wss test runs bare and verification is the
explicit opt-in.
2) Make fx_bench a real pass/fail test against known hardware.
- Collected a golden per-effect frame-cycle reference from a real ESP32-C6 rig
DUT (goldens/fx_bench.esp32c6.json, 72 samples), wired into runfiles.
- compare_to_golden (fx_bench_core, unit-tested): a run must match the golden's
measuredFrameCycles per effect within margin. Show cycles (transmit path,
noisier) aren't gated. Default margin 5% — the ~70 real compute effects hold
≤2.3% across runs — with looser per-label margins on the two tiny anchors
whose relative noise is higher: empty 10%, sweep16 15% (observed worst 5.1%
/ 11.5% over 3 runs). Validated: 2 independent real runs pass, 0 offenders.
- `--out` is now optional: defaults to the test sandbox
($TEST_UNDECLARED_OUTPUTS_DIR or a tempdir); an explicit path still wins.
- New knobs: --golden, --margin, --no-golden-check, --emit-golden (regenerate).
hitl_shim: all five targets now run bare, so the per-target default args are
dropped. //pi/hitl/tests unit suite + all harness targets build; fx_bench
end-to-end on the rig writes to the sandbox and runs the golden check.

The target failed bare with FileNotFoundError on `…/mapping_trigger.runfiles/_main/fx_compiler/fx_compile_/fx_compile`. Two bugs, same as fx_bench avoids: `_rlocation` returned Rlocation()'s CONSTRUCTED path without checking the file exists, so default_fx_compile's first (wrong) candidate `_/fx_compile` always won and the correct `_main/fx_compiler/fx_compile` fallback never ran; compile_fx then exec'd a non-existent path. Existence-check `_rlocation` (like fx_bench) and prefer the target-name rloc. Confirmed on the rig: fx_compile resolves, empty.fx compiles, and start_mapping asserts pass (exit 0) — the last of the five HITL targets green.

…test Both fx_bench tests now share ONE source of truth, web/tests/testdata/device-bench-esp32c6.json — a full device-measurement bundle (72 real ESP32-C6 programs, fxbBase64 kept) plus an `fxBenchMargins` block: - HITL (pi/hitl/harness:fx_bench) reads it from runfiles (cross-package dep on //web:tests/testdata/...) and gates a fresh run's per-effect frame cycles vs the golden within margin (5% default; empty 10%, sweep16 15%). Confirmed on the rig: reads the golden from runfiles, 72 effects, PASS. - The web estimator test (deviceProfileHardware.test.ts) imports the same file, fits buildDeviceProfile on the 65 fit programs and validates a 7-program held-out spread of real effects — RMS 9.9%, gated at 13%. fx_bench_core: compare_to_golden / bundle_to_golden now speak the bundle+margins format (parseDeviceBundle ignores fxBenchMargins, so the estimator is unaffected). fx_bench --emit-golden regenerates the unified file. Dropped the separate slimmed goldens/ file. Also adds a FIT_DEBUG per-program residual dump to the fit tool. NOTE on the estimator margin: the linear sum-of-op-costs model tops out ~10% RMS here — it over-predicts the cheapest real effects (empty +34%, lavalamp +19%), and reweighting toward relative error hurts generalization. 13% is the tightest honest gate; reaching ~5% needs a richer cost model (structural/nonlinear features + targeted microbenchmarks), tracked as follow-up. Tests: //web:unit_tests (52) + typecheck, //pi/hitl/tests, and fx_bench on the rig all pass.

Record the estimator-accuracy follow-up: the linear opcode cost model over- predicts the cheapest real effects (measured via FIT_DEBUG), tops out ~10% RMS so the estimator gate is 13% not 5%, relative-weighting was tried and hurts generalization, and the concrete directions + offline/rig loop to close the gap.

FUG-85 Flashing esp from the browser on Android doesn't work
Seems that this may be due to no native USB serial drivers on Android. Gemini thinks there might be workarounds: Workarounds for Wired USB SerialWeb Serial Polyfill: Developers can use the Google Web Serial Polyfill combined with WebUSB, though this is restricted to specific unassigned USB CDC-ACM hardware classes that the Android OS hasn't already claimed with a built-in driver.Third-Party Bridges: Use external hardware or local Wi-Fi/Bluetooth serial bridging apps (like a local server or ESP32 bridge) to relay serial data to the Android browser over a network socket or Bluetooth.Dedicated Native Apps: For reliable wired USB-to-serial communication on Android (using OTG cables), a native Android application utilizing the android.hardware.usb host API or third-party libraries like UsbSerialForAndroid is still required instead of Chrome.Would you like details on how to set up the Web Serial Polyfill using WebUSB? Investigate of any of these might work and implement a fix. |

Adding pi/hitl/scripts/BUILD.bazel for the hitl_shim py_binary turned
pi/hitl/scripts/ into its own Bazel package, which orphaned the scripts/*.sh
files that //pi/hitl references as `//pi/hitl:scripts/seed-wifi.sh` — so `bazel
query //...` (the hitl_tests CI job's discovery step) failed to load //pi/hitl
("'pi/hitl/scripts' is a subpackage"), taking the whole job down before any test
ran. Drop scripts/BUILD.bazel and declare `//pi/hitl:hitl_shim` in pi/hitl/BUILD
(srcs = scripts/hitl_shim.py) so scripts/ stays part of //pi/hitl and the seed
targets resolve again.
Verified: `bazel build --nobuild //...` loads clean, the hitl-tag query returns
the five harness tests, and hitl_shim / seed_wifi / seed_tailscale_authkey all
resolve.

map_upload reddened CI on `ws never came up … timed out during opening handshake`: after a cold --erase-fs flash the DUT reformats littlefs, joins WiFi, re-issues the LAN cert and restarts the TLS server, which occasionally runs past the 25s wss-settle window. The four on-hardware wss opens (map_upload, mapping, e2e, fx_bench) now wait 60s. Pure slack — a warm DUT answers on the first attempt (0 retries observed), so the happy path is unchanged; the extra window is only consumed when a cold boot is genuinely slow to bring up wss:443. Confirmed flaky first (3 PASS / 2 FAIL across CI + local rig runs), in two independent spots: this settle race, and inherent BLE/improv provisioning (already bounded by 3 retries + hard reset, left as-is).

The intermittent map_upload/e2e failures on the rig were misdirected
provisioning, not a firmware or timing bug. A serial trace showed the harness
flashing the reserved DUT (c6-123170 = 8C:FD:49:12:31:72 "Led Widget CA2BFE",
which booted healthy with wss on :443) while the BLE provisioner connected to a
DIFFERENT board in RF range — a ghost left renamed + powered by a prior e2e run
("HITL Test 13679", 58:E6:C5:FA:33:06) — and ran the whole test against it. That
stray board's drifting TLS state produced the ConnectionResetError storms and
the mangled-first-frame "envelope has no message set" errors.
_run_provisioner never passed --address, so the scan took whatever named Improv
device answered first. Fix: read the reserved board's BLE advertising MAC off
its OWN serial (hitl-monitor reads that specific USB port, so the MAC is
guaranteed to be the flashed board), then pin the Improv scan to it. A stray
board can no longer be provisioned in place of ours; a failed MAC read falls
back to the old name scan with a warning. The reset-to-read also lands the board
in the clean soft-AP first-join state provisioning already prefers.
Centralized in provision.py, so all five hardware drivers benefit. Adds
//pi/hitl/harness:serial_probe, the diagnostic that found this (flash, stream
serial while provisioning + hammering the wss open).
Validated on the rig: map_upload 4/4 + e2e all green, every run pinned to
8c:fd:49:12:31:72 — vs the prior pass/fail randomness on the stray board.

Widen the blanket default to a deliberately safe 10% until we do a comprehensive per-effect run-to-run variance measurement and tighten it back down. sweep16 keeps its looser 15%; the now-redundant empty override (was 10%) drops out under the new default. Updated both the golden's fxBenchMargins block and the _GOLDEN_* emit-golden constants so a regeneration reproduces the file.

Started as "flash from Android Chrome" and grew to fix the rename → reconnect
failures it exposed, refresh the devices page around them, and get the full HITL
harness suite green (including a real pass/fail for the FX cost estimator).
Android WebUSB flashing (
web/src/flash,patches/)Flashing from Android Chrome failed at three successive points; the whole
detect → write → verify path now works on the ESP32‑C6's native USB:
navigator.serialexists. Chromefor Android 138 shipped Web Serial, but only over Bluetooth — so the native
picker listed speakers, never the USB board. Install the WebUSB‑backed polyfill
whenever WebUSB is present AND (no native Serial OR Android).
navigator.serialis a read‑only accessor once native, so install via
Object.defineProperty(a plain assignment threw at import and took the flashSheet chunk down).
web-serial-polyfill's zero‑length enqueue (pnpm patch): the C6'sUSB‑Serial/JTAG emits zero‑length USB packets; the polyfill enqueued them into a
byte stream (
chunk is empty→ killed the read loop → "No serial datareceived"). Guard the enqueue on
byteLength > 0.closing and reopening the port; the C6's native USB‑Serial/JTAG goes silent when
its interface is re‑claimed mid‑flash, and its baud is nominal anyway — keep
native‑USB (VID
0x303a) at 115200; real UART bridges still get 921600.Firmware: rename no longer wedges

restart. Two fixes: (1) the rename no longer re‑issues the cert at all when the
STA IP is unchanged (only the hostname changed; the app connects by IP SAN) — so
wss stays up and trusted, and the app's socket never even drops; (2) the
restarts that are needed (real IP change) now yield for the idle task to reclaim
the old stack and only commit

The FX estimator gate is 13%, not the desired 5% — that's the linear

relative‑error weighting hurts generalization). Root cause + concrete directions
