+  * Bump to 3bc0da1 — picks up daedalus-v4l2 PR #15.  Per-frame
+    `decoder: OK ...` log line gains `decode_us=N` (libavcodec
+    send_packet + receive_frame wall-clock cost in microseconds).
+    New `decoder stats` summary line every 60 decoded frames with
+    codec, fps, avg decode_us, MBs/s throughput, B/MB bitrate.
+  * Pure observability — no decode-path behaviour change.
+    Establishes baseline metrics for the substitution work in
+    daedalus-v4l2#11 step 2 (replacing libavcodec primitives with
+    daedalus-fourier kernels one cycle at a time).
+  * On Pi CM5 / bbb 720p H.264 baseline: ~4 ms decode_us / 24 fps
+    / 90 K MBs/s — workload is well under 1 % of any single
+    daedalus-fourier kernel's NEON ceiling.
+  * Wire protocol unchanged.  No daedalus-v4l2-dkms bump needed.
