Add the CTS under src/python/isaaccapture/cts/: the hand suite in cts/hand (capture, checker, oracle) and the shared core in cts/common (MCAP reading, the check model, verdicts, the replay panel parts and the submission archive). A take is one scripted recording; the checker reads its MCAP with only mcap and flatbuffers and returns pass, fail, retake or insufficient_data. The docs gain a Device Conformance section under Devices: overview, setup, the hand suite and submission. docs/tools/cts_media regenerates the step animations and the hand rehearsal track. cts/ stays out of the wheel, and *.wav and *.mp3 go through Git LFS.

@src/python/isaaccapture/cts/common/src/cts_common/panel/track.py:
- Around line 98-106: Update TrackBuilder._stamp and Track.update so each track
uses a single clock domain when computing times_s and interval_ms. Handle frames
with sample_time_ns=None without mixing log_time_ns values into an established
sample-time sequence; either normalize every log-time fallback with one fixed
sample/log offset, including buffered frames, or reuse the previous sample
timestamp and set that frame’s interval to None. Preserve correct behavior for
clock tracking, origin, index_at, duration, and rate calculations.
Review comments at @src/python/isaaccapture/cts/hand/capture/make_labels.py:
- Around line 84-86: Update write() to persist the windows-only sidecar before
running audit(recording, windows), while preserving the no-windows early return.
Wrap the audit call so any failure still retains the windows and produces a BAD
audit row, then use a safe fallback for first_ns and info.get("records") when
derived fields are unavailable.
Review comments at
@src/python/isaaccapture/cts/hand/checker/src/hand_cts/mcap_source.py:
- Around line 94-101: Update the message-decoding loop around decode_record to
catch struct.error and IndexError only during payload decoding, then raise
mcap_reader.UnreadableRecording with the path, sequence, topic, schema, and
original error chained. Yield the decoded frame after the guarded call, keeping
mcap_reader.messages and downstream checks outside the wrapper so faults inside
checks still propagate.

…udit fails A hand record whose FlatBuffer cannot be decoded raised struct.error out of the checker, which then exited 1, the status of a fail. The frame source now raises UnreadableRecording for it, so the CLI exits 4. make_labels wrote the sidecar only after the audit had read the take, so an unreadable take lost its step windows, which the recording cannot regenerate. The windows are written first, and an unreadable take is reported as one BAD row. The panel's rate filters use math.isnan instead of comparing a value with itself.

Description
Adds the CTS, a conformance test suite for device integrations, under
src/python/isaaccapture/cts/, and a Device Conformance section on the docs site that walks an integrator through it. A vendor records one scripted take with their device; the checker reads the MCAP and returns a verdict:pass,fail(the device is at fault),retake(the take was not performed as scripted) orinsufficient_data. A browser panel replays the take alongside the results and packages it for submission.The full-body suite follows in its own PR once this one merges.
The suite

It holds nothing schema-specific; a suite subclasses the shared checks to place them in its own groups.The hand suite has
