- Line 69: Update the `sync_matching_threshold_ms` table entry to clarify that
5.0 ms is only the upstream grouping window and that `Odometry::Track` rejects
image pairs differing by 1 ms or more; advise configuring synchronization so
resulting image timestamp differences stay strictly below 1 ms.
Review comments at @TROUBLESHOOTING.md:
- Around line 361-362: Qualify the claim about `track()` returning poses without
an error: stale image pairs that fail `CheckImages` timestamp validation can
cause an error. State that the no-error behavior applies only to inputs that
pass timestamp validation, or explicitly mention this error case.

Δ is the change from the median of the last 14 runs. ⚠ marks a KPI that, in this configuration, is more than 5% off every level seen before (in at least 2 runs, first at least 7 days ago) and worse than all of them; FPS is not checked here, against main's nightly history. Failed counts sequences that failed. Regressions (2, marked ⚠ above):

Feeding track() one camera per call looked allowed, since partial image sets are supported, but cuVSLAM matches cameras only within a call. State the rule in the Odometry::Track and Python track() docs and the README, add a short TROUBLESHOOTING section with remedies, and fix skill docs that suggested a wider sync threshold or described image_jitter_threshold_ms as a tolerance between cameras. Also correct the timestamp source (images[0]) and the nonexistent is_valid in Odometry.track. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

set is saved only when its maximum timestamp difference is strictly less than
sync_threshold_ns; clarify that a difference equal to or greater than the
threshold is rejected.
Review comments at @TROUBLESHOOTING.md:
- Line 362: Update the timestamp-check guidance in TROUBLESHOOTING.md to remove
the unsupported claims that tracking will freeze, drift, or diverge with an IMU;
unless a documented contract or synchronization-specific test supports those
outcomes, state only that tracking accuracy is not guaranteed.

bag2edex keeps a frame set only when its timestamps differ by less than sync_threshold_ns, and track() rejects images 1 ms or more apart, so say so exactly. No contract or test backs the claim that such input freezes, drifts or, with an IMU, diverges the pose, and the outcome varies by odometry mode, so state only that tracking accuracy is not guaranteed.

cuvslam-skills/cuvslam-troubleshoot/SKILL.md:93
🎯 Functional Correctness | 🟡 Minor | ⚡ Quick winDocument the sequencer timeout behavior.
image_jitter_threshold_msis not warning-only. The Isaac ROS message sequencer uses it as a timeout. When the image gap exceeds the threshold, the sequencer flushes the buffered image batch toTrack. The node also logs a warning. The threshold does not drop that batch, but the current wording omits this delivery behavior.Suggested fix
- `image_jitter_threshold_ms` — tolerated gap between consecutive frames (exceeding it only logs a warning), not a tolerance between cameras + `image_jitter_threshold_ms` — gap threshold for consecutive frames; exceeding it flushes the image batch to `Track` and logs a warning, not a tolerance between cameras🤖 Prompt for AI Agents

Review asked the README to say unsynchronized cameras are not supported, suggest separate trackers and link the TROUBLESHOOTING section; the sync bullet now does that. Review also asked whether the Isaac ROS defaults come from the node and whether the skill can check them. They are the declare_parameter values in release-4.3 visual_slam_node.cpp, except imu_frame, which defaults to "" there, not imu. The reference now names that source and tells the skill to check it for the user's release. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
