Technical field report:
v2.4 rollout.

Sentient inspection v2.4 ships to all Foundry units this week. Detection latency drops 40%, drift heatmap precision lands at 0.4mm, and the BIM overlay engine picks up four new IFC primitive types.

What shipped

v2.4 is the largest single drop we've put through the Foundry channel since the program opened. Three engines were rebuilt: sentient inspection, drift heatmap, and the IFC primitive parser. The visor firmware bumps to 1.04, with a new thermal envelope that lets us run the inspection NPU at sustained 21 TOPS without throttle.

The rollout is staged across the next 14 days. Foundry units are receiving the OTA in cohorts, with telemetry rolling back to engineering in 30-second windows.

Sentient inspection v2.4

We rebuilt the inspection model from scratch with a new vision-language backbone trained on the largest as-built corpus we've ever assembled. The model now handles partial occlusion (formwork, scaffolding, dust) with the precision we used to require a fully-cleared element to achieve.

Inspectors using v2.4 in pilot reported a 61% reduction in inspection time, and a 38% increase in flagged deficiencies that turned out to be true positives. The false-positive rate dropped to 1.6%.

Drift heatmap engine

The drift heatmap is now sub-millimeter against the BIM record set. We re-engineered the visor's stereo capture pipeline to fuse LiDAR returns at 30Hz with the photogrammetric depth field, then run the alignment in a tight inner loop on the visor itself.

What this means in the field: when a beam shifts 4mm out of spec, you don't see it in your QA report next week. You see it in your visor before the next pour.

What's next

v2.5 enters Foundry channel in mid-May. Headline change: Tactical Crew Comms v2.1 lands as a default capability across all units, with role-aware silent badges for hazardous zones. We're also opening early access to the AI Photogrammetry Workspace for select Foundry GCs.

Field reports welcome on the Foundry channel. We read every one.
