- LICENSE (GPL-3.0) at the root; an MIT LICENSE in each components/aes67_*
and in web/, so they travel with the code when reused.
- THIRD_PARTY.md: third-party code and licences, and the known conflict of
the Espressif binary audio libraries with GPL-3.0 (firmware contains cspot).
- CLAUDE.md: rule to keep GPL code out of the core; phase 2 item to replace
the Espressif binaries (opencore-aacdec, Speex resampler).

An upload during an active Spotify session crawled (~10 kB/s, 197 s)
and ended in a reset (seen twice). Workaround:
- aes67_ota_on_update(cb): cb(true) right before an accepted upload
writes flash, cb(false) if it then fails.
- The player pauses Spotify (spotify_pause -> SpircHandler::setPause, the
app follows) and suspends HLS fetching (hls_suspend); resumed if the
upload fails. AES67 TX keeps running (silence).
- Verified: upload during Spotify playback paused the session and
installed in 25.8 s (normal for 2 MB), clean reboot and self-test.
Root cause still open (noted in CLAUDE.md with the other cspot items).

GET /api/ota listed a half-written upload or a rolled-back image as
'previous'. Only report it when esp_ota_check_rollback_is_possible().

- aes67_ota: GET /api/ota (version, project, build_date, idf, running,
previous, previous_version, pending_verify, can_rollback), POST
/api/ota streamed into the inactive slot (4 KiB chunks), POST
/api/ota/confirm and /api/ota/rollback.
- Rejected before any flash write: bad magic, wrong chip, wrong
project_name, chip revision outside the image's min/max range.
esp_ota_end verifies the whole image.
- Self-test on a pending image: IP address plus HTTP 200 from our own
/api/status within 60 s marks it valid; otherwise mark invalid and
reboot into the previous slot. A crash before that is rolled back by
the bootloader.
- CONFIG_AES67_OTA_SELFTEST_FORCE_FAIL (test builds only) forces a
failed self-test.
- aes67_web: web_reboot_later() shared by /api/reboot and OTA.

- Board checked with esptool: ESP32-P4 rev v1.3 (engineering silicon),
32 MB GigaDevice flash. Rev <3 support and 32 MB set in sdkconfig.defaults.
- OTA partition layout: nvs, otadata, phy_init, ota_0/ota_1 (6 MB each,
below 16 MB), coredump; no factory app. Partition table at 0x10000 so
the bootloader can grow.
- App rollback enabled in the bootloader from the start.
- PROJECT_VER from git describe --tags --always --dirty.
- Empty stubs for the nine aes67_* core components; main logs version
and chip revision.
- Built with ESP-IDF v5.5.5; not yet flashed.
