App 2.43.1: Halloween's bats can be seen

They were near-black and small on the darkest part of the sky. Now a moonlit purple-grey with a light edge, a third larger. Not tried on the car. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01LhzAVaUyqcw5PkGjz4mWW6

 name: car-logs
 description: Download the signal recordings the MG4 sent to the car server (fetch-logs) and read them. Use when the owner says a recording is on the server, asks to get, download or look at the car's logs or recordings, or after a test drive with the signal recorder.
 ---
 # Fetch and read the car's recordings
 The app's signal recorder (Logs tab, `SignalRecorder`) sends each finished recording to the
 car server (`LogOutbox`, `PUT /v1/logs/{name}`); the server keeps the newest 200
 (`server/logs.go`). `fetch-logs` in the dev shell downloads the ones not yet in `logs/`.
 ## Fetch
 ```sh
 nix develop -c fetch-logs
 ```
 It prints each new file (`logs/signal-recording-YYYYMMDD-HHMMSS.txt`) and `fetch-logs: N new`.
 The token comes from `~/.config/nilsmg4/logs-token` (the server's `LOGS_TOKEN`) and goes only in
 a header.
 - **Never print, cat or echo the token**, and never pass it on a command line you show. Do not
  read the token file.
 - `no token`: ask the owner to put the server's `LOGS_TOKEN` in `~/.config/nilsmg4/logs-token`
  (and in `k8s/secrets/secrets.yaml`, then apply it). Do not create or fill it yourself.
 - HTTP 401: the file and the server's Secret differ. HTTP 404: reading is off (no
  `LOGS_TOKEN` on the server) or the server is older than 2.9.0. The owner applies manifests and
  Secrets; never run `kubectl` against the cluster, not even read-only.
 - `0 new`: nothing arrived. In the car, the Logs tab says "Sent to the server." or how many wait
  and why (no server set up, server not reached, an HTTP status); the car retries every 2
  minutes while the service runs.
 ## Read
 The files are plain text but `file` may call them data; search with `rg -a`. Newest first:
 `ls -t logs/`. If the owner said what they did and when (e.g. "ACC on at 08:50, set speed
 100→90 at 08:51"), line those times up with the timeline.
 A recording has four parts, in this order:
 1. Header: captures, start time, app version.
 2. **Steering-wheel keys and notes.** The first note says whether listening worked:
   `listening to N assistance properties (M refused)`, or `not possible (<reason>)`.
 3. **Assistance properties heard** (`EVHardware.listenToProperties` on `AssistBlock`, the
   `0x21x0A1xx` block): change events, properties whose value changed first. This is where a
   value shows up that the head unit fills only while someone listens.
 4. **Changed values (polled)**, rarest first, then **Everything, in order**: every capture
   (about every 5 s) with what changed since the last.
 Useful cuts:
 ```sh
 rg -a 'listening to' logs/<file>                                   # did listening work
 awk '/^Assistance properties heard/,/^$/' logs/<file>              # what listening heard
 rg -a 'A15B|A15A' logs/<file>                                      # one property's history
 rg -a 'getLatestSpeed' logs/<file> | head                          # the car's speed over time
 ```
 Known leads (SPECS.md, 2026-10-27): `0x2160A15B` is `AAD_EPTCCTRGTSPD`, by its name the cruise
 control's target speed (0.0 when only polled); `0x2140A15A` moved between 3 and 7;
 `0x2160A1A3`/`0x2160A1A4` counted up by 0.1. A value that tracks what the owner did at the
 times they name is a lead; say how sure it is, and that it is not confirmed until a second
 drive shows the same.
 ## Music-sources checks
 `fetch-logs` also brings `media-probe-YYYYMMDD-HHMMSS.txt` (Logs tab, "Check music sources",
 `MediaProbe`). Three parts: audio players (use, app, state), active media sessions with state
 and song (TITLE, ARTIST, ALBUM, ALBUM_ART as a size or ALBUM_ART_URI), and the media browser
 services by name (2.42.1 on; 2.42.0 also connected to them, which stopped the music). CarPlay's
 session is `com.allgo.remoteui.mediabrowserservice`, Bluetooth's `com.android.bluetooth`. Ask what was playing
 when the check ran.
 ## Rules
 - Recordings and checks are the car's data: `logs/`, `/signal-recording-*.txt` and
  `/media-probe-*.txt` are gitignored. Never
  commit, publish or upload them anywhere.
 - Findings that change what the project knows go into a `SPECS.md` done-log entry, as usual.

  jack-o'-lantern with the speed in its grin, burning yellow or, regenerating, green; an arch of
  embers = power; a potion flask = battery; a tombstone and bats = range; the hill = the last two
  minutes of power. What a value lights is `Tally` (pure, unit-tested: an unread value lights
  nothing). The static scene is drawn once per size into a bitmap (about 4.5 MB while the view is
  attached), so a frame only draws the readings; flags, flames, bats, bubbles and the ghost move
  only while the car moves. Tests and lint pass. Emulator with sample values, panel and full

  services.** In the car, 2.42.0's check (14:26, Bluetooth music playing) made the head unit ask
  whether to allow access to media (the owner agreed) and **stopped the Bluetooth music**: it
  connected to every media browser service, and among them the AOSP car radio's
  (`com.android.car.radio/.RadioService`, which answered "connecting", most likely taking the
  audio) and the Local Media Player (`com.android.car.media.localmediaplayer`, whose permission
  request is most likely the question; it may now read media files). My claim that the check only
  read was wrong: binding another app's service starts it. Now the services are only listed.
  Nothing lost: the active sessions alone carried everything — **Bluetooth**
  (`com.android.bluetooth`: title, artist, album, duration, track, cover as a file path, playing)
  and **CarPlay** (`com.allgo.remoteui.mediabrowserservice`: title, artist, duration, paused) —
  readable with MEDIA_CONTENT_CONTROL, no connection needed. Services on the car: CarPlay's,
  Bluetooth A2DP, Local Media Player, the AOSP car radio, SAIC's radio (DAB, "Brillux Radio"),
  SAIC's USB 1/2 and online media, and SAIC's video browser. Tests and lint pass; not run on the
  emulator (stopped for low memory; the change only removes code); not tried on the car.

  `MediaProbeText`; owner: "is it possible to show playing music in our dashboard as well?", then
  "yes start the probe"). Before a now-playing display, it finds where the head unit tells what is
  playing, read only: the players Android's audio service reports (use, app, state), the active
  media sessions (`MediaSessionManager.getActiveSessions`, MEDIA_CONTENT_CONTROL, which the system
  user has) with their song, and every media browser service, each connected to, its session read
  and disconnected. CarPlay's is tried even when not listed:
  `com.allgo.remoteui.mediabrowserservice/.RemoteUIMediaBrowserService`, which the car's own media
  library (`com.saicmotor.sdk.media…MediaPlayControlManager` in Allgo's APK) reads CarPlay's title,
  artist, album and cover from through a plain `MediaBrowser`. Nothing of Allgo's is changed and
  nothing is played, paused or skipped. The report (`media-probe-YYYYMMDD-HHMMSS.txt`) goes where
  a recording goes, through the shared `SignalRecorder.saveCopies`: the app, a USB stick, the
  server (`fetch-logs`). Unit tests for the text; tests and lint pass. Emulator (Android 9): the
  players are read with their app and state (the system APIs answer the system user), the
  sessions are readable (none there, no SecurityException), the AOSP music app's browser service
  connects and is read, CarPlay's (not installed there) is "refused or failed", and the report
  lands in the outbox. **Not tried on the car.** Unknown until then: whether CarPlay's service
  lets the app connect, and whether the radio, Bluetooth and USB sources publish a session.

 ## Día de Muertos
 After the ofrenda, the altar families in Mexico build to welcome their dead back for a visit: a
 celebration, so bright and warm rather than frightening. The papel picado across the top is the
 battery, one cut-paper flag per 10 %, those not lit hanging dark, turning red with "BATTERY LOW"
 below 20 %. The calavera in the middle, a decorated sugar skull with marigolds (cempasúchil) for
 eyes, has the speed on its forehead; the ring of marigolds round it is the power, clockwise while
 drawing, turquoise and anticlockwise while regenerating. The altar's candles are the range, one
 per 50 km. The path of marigold petals along the bottom, which in the tradition leads the visitors
 home, is the last two minutes of power. On the right the clock in a tin frame, P R N D as small
 marigolds, and trip, usage, climate and odometer on the altar cloth. While you drive the flags
 sway and the flames flicker. The app turns the papel picado's pink with it.

 ## Halloween
 A graveyard hill under a full moon. The jack-o'-lantern has the speed cut into its grin, and its
 carving burns candle yellow while drawing and witch-fire green while regenerating; the arch of
 embers over it is the power, from the left while drawing and from the right while regenerating.
 The potion flask is the battery, red with "BATTERY LOW" blinking below 20 %. The tombstone reads
 the range ("here lies … km"), and the bats are the range too, one per 50 km; P R N D are small
 gravestones, the one engaged lit. The moon holds the clock, a sign hanging from a cobweb has trip,
 usage, climate and odometer, and the hill along the bottom is the last two minutes of power. While
 you drive the bats fly, the potion bubbles and the ghost floats (where there is room for it, as on
 this screen). The app turns the pumpkin's orange with it.

 *
 * In the middle a jack-o'-lantern with the speed cut into its grin; its carving burns candle yellow
 * while drawing and witch-fire green while regenerating, and the arch of embers over it is the
 * power, left to right while drawing, green and right to left while regenerating. On the left a
 * potion flask: the battery, red with "BATTERY LOW" blinking below 20 %, under a sign hanging from
 * a cobweb with trip, usage, climate and odometer. On the right the moon holds the clock, and a
 * tombstone reads the range ("here lies … km"); P R N D are four small gravestones, the one engaged
 * lit. The bats are the range too, one per 50 km. The hill along the bottom is the last two minutes
 * of power, rising with it, in orange or, where it regenerated, green. Unread values show "—" and
 * light nothing.
 *
 * The night sky is drawn once into a bitmap per size; only the rest goes over it. Bats, bubbles and
 * the ghost move (about 30 frames a second) only while the car moves and the view is on screen.

nilsandClaude Opus 5.5	adc2c86303	App 2.43.0: Overview styles Día de Muertos and Halloween Día de Muertos is an ofrenda: papel picado for the battery, a calavera with the speed in a ring of marigolds for the power, candles for the range, a path of petals for the last two minutes of power. Halloween is a graveyard hill: a jack-o'-lantern with the speed in its grin, embers for the power, a potion flask for the battery, a tombstone and bats for the range. Each has its own palette; Tally counts what a value lights.
