- main/audio_out: one converter instance per source (own rate converter
state): s16 any rate/channels -> 48 kHz stereo int32 -> ring.
- player_write(src, ...) only writes for the active source, drops the
rest; player_src_t is public in player.h.
- HLS decoder uses audio_out (no behaviour change).
- Verified: HLS still sample exact (441344 -> 480375 frames per
10.008 s segment), buffer ~4 s, 0 underruns.

- main/decoder: MPEG-TS demux (packets reassembled across HTTP chunks,
PAT -> PMT -> first ADTS-AAC PID, PES headers stripped) feeding the
esp_audio_codec simple AAC decoder (ADTS, AAC-Plus enabled for HE-AAC
v1/v2 variants). 7.3 only counts and logs PCM per segment.
- esp_audio_codec pinned to ~2.5.0: 2.6+ needs P4 rev >= 3 (this board
is rev 1.3). Noted in CLAUDE.md, also for esp_audio_effects < 1.4.
- The library's combined TS decoder lost ~8% of the frames (segments
decoded to 7.9-9.6 s, "decode error -1"); with the own demux every
segment is sample exact: 441344 / 440320 frames = 10.008 / 9.985 s,
matching EXTINF 10.0078 / 9.9846 (431 / 430 AAC frames), no errors.

- main/hls: task active while source.mode is hls/auto and hls_url is
set. esp_http_client over HTTPS (IDF certificate bundle), redirects
followed (max 5), streamed reads in 4 KB chunks to a sink callback.
- Master playlist: highest BANDWIDTH variant; URL resolution for
absolute, host-relative and path-relative references; CRLF tolerant.
- Media playlist: TARGETDURATION, MEDIA-SEQUENCE, segments; start 3
segments behind the live edge, fetch each new one in order, skip ahead
if the window moved past us, reload after target/2 when nothing is new.
- Verified with Triple J Hottest (ABC, Akamai): 252 kbit/s AAC-LC
variant chosen, 3 back-fill segments then one new ~10 s segment at a
time, ~303 KB in ~1.25 s each; heap 439 KB, PSRAM 31.9 MB free.

- main/audio_ring: SPSC ring of interleaved int32 frames in PSRAM
(4 s at 48 kHz stereo), lock-free with acquire/release counters; the
TX pull callback never blocks.
- main/player: source selection from source.mode and the pull callback
for aes67_tx. tone -> the core's PTP-phased 1 kHz tone; off -> silence;
hls/spotify -> ring with 1 s prefill (silence while buffering is not an
underrun; running dry is, and prefills again). Status fields
active_source, source_state, spotify_state, buffer_ms. source config
applies live.
- New source.mode "tone" (validation, UI dropdown, doc) for commissioning.
- Temporary 440 Hz producer in hls mode (until the HLS player exists).
- Verified: tone 999.7 Hz -18 dBFS; off silent; hls 440.0 Hz with max
sample step 60816 (ideal sine 60825, i.e. no discontinuities), buffer
3983 ms, 0 underruns; spotify silent/not implemented.

- aes67_sdp_sap: aes67_sdp_build() builds the AES67 SDP (RFC 4566 +
RFC 7273) with the same lines and order as the web UI preview;
GET /stream.sdp serves it as application/sdp.
- aes67_ptp: public aes67_ptp_gm_id(), aes67_ptp_locked(),
aes67_ptp_now_ns(). Clock IDs are now uppercase (RFC 7273 style), also
in status.ptp, which the UI copies into ts-refclk.
- aes67_net: aes67_net_netif() returns the AES67 interface.
- Verified on board: /stream.sdp byte-identical to the UI's sdp() for
the same config/status; mono, L16, ptime 0.333, ttl 8, clk_offset
4294967295 and session_ver all follow the config.

- 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.

- aes67_web/cfg.c: cfg_register(group, defaults, validate, apply),
cfg_override_defaults() for project defaults, cfg_get(). Stored values
are loaded on register and merged over defaults (known keys, matching
types). NVS keeps only keys that differ from defaults, one JSON string
per group, so new firmware defaults still reach untouched settings.
- POST /api/config: type check against defaults, per-group validation,
nothing stored unless every group passes; 400 "group.key: reason".
Unknown keys/groups are ignored. Returns the new config.
- Core groups registered by their components with the UI's ranges:
ptp (aes67_ptp), aes67 (aes67_tx, incl. multicast range and mono_sum
=> 1 channel), net/inet (aes67_net), log (aes67_syslog).
- Project: PROJECT.def overrides (hostname p4-aes67, name P4 AES67) and
the "source" group in main/project_cfg.c.
- Config is stored only; nothing is applied live yet.
- Verified on board: defaults, valid save, 8 rejected values (nothing
stored), persistence across reboot, restore to defaults.

- aes67_web: httpd (wildcard URI matching), serves web/index.html embedded
via EMBED_TXTFILES, status registry (status_register) and route registry
(web_register_uri), GET /api/status, POST /api/reboot (restarts 0.5 s
after the response).
- Status fields come from each core component: aes67_net (ip, aes67_ip,
mac, link), aes67_health (fw, uptime_s, heap_free, psram_free),
aes67_tx stub (tx_packets, underruns = 0). No ptp object yet, so the UI
shows "no data".
- Verified on board: / serves index.html byte-identical (27601 B),
/api/status returns live values, reboot via API returns in ~12 s.

- aes67_board: Waveshare ESP32-P4-ETH pin profile and EMAC + IP101 driver
install (PHY addr 1, reset GPIO51, ref clock in on GPIO50).
- aes67_net: Ethernet netif with DHCP client; logs link up/down (speed,
duplex, MAC) and the DHCP lease.
- Verified on board: 100 Mbps full duplex, DHCP lease in ~8 s, ping
0% loss, ~0.2 ms RTT.

- 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.
