- 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).

- aes67_cfg: cfg_set_number(group, key, value, apply) for firmware-side
changes, stored in NVS like a POST; apply can be skipped.
- aes67_sdp_sap: once a second, a change of the PTP GM (ts-refclk) bumps
aes67.session_ver without re-applying the aes67 group (no stream
restart); SAP then re-announces. Runs whether or not SAP is on.
- Verified with ptp4l as a normal clock (p1 128): board auto (p1 250)
steps down to SLAVE (session_ver 1->2); role master p1 100 via API ->
board MASTER at once (->3); back to auto p1 250 -> ptp4l takes over
within ~1 s, board SLAVE again (->4).

- aes67_sdp_sap: SAP (RFC 2974) announcer task. SAPv1 to
239.255.255.255:9875 every 30 s and within 1 s of any SDP change
(config save, GM change), with the old hash deleted first. Active while
aes67.discovery = sap, the stream is enabled, the AES67 interface has
an IP and a PTP GM is known. Deletion when that stops and at shutdown
(reboot/OTA) via a shutdown handler. TTL = aes67.ttl.
- Docs: SAP implementation notes; session_ver bump on GM change still open.
- Verified with a SAP listener: 30 s repeats with a stable hash; rename
-> delete old + announce new (o= version follows); manual -> delete;
sap -> announce; reboot and OTA -> delete at shutdown, first announce
after boot only once the GM is known.

- 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.

- 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.
