Nail set wrong
In at an angle, proud, or short. A senior would stop the gun. The wall still looks finished from the aisle.
Product
Prodius is a trade-specialized vision model on a brim camera. The camera is the eyes. The product is a senior in that trade, watching the work against the drawings. Framing gets a senior framer. Rebar gets a senior ironworker. The flag comes while the work is still open.
Hardware
A molded clip wraps the front of the hard hat. The module looks where the worker looks. That is the only hardware. The rest is the senior.

A molded clip wraps the front brim so the camera sits flush and looks where the worker looks. No cage. No tape.
The model is the skill: a senior framer, a senior ironworker, a senior finisher. One trade. Deep, not wide.
What a senior would stop the crew for comes back before close-in. The super sees the list. The crew can still reach the work.
Software
The feed from the helmet. The miss marked on the work. The spec from this job's sheets. Tap a flag to see where it sits in the bay.

Against the drawings
Sheet A2.1. Stud 14 · 16d @ 6 in o.c.. The senior is checking this job, this trade, this bay.
What the senior watches
In at an angle, proud, or short. A senior would stop the gun. The wall still looks finished from the aisle.
A plate, stud, or hanger missing the count in the spec. Easy to miss when the crew is moving.
Spacing walks off the drawings by a bay or two. Inspectors catch it when they have time. Often they do not.
A skipped tie, a missing member, an unfinished joint. Small. Then someone covers it.
The loop
The senior is only useful if it can see. It can only see if it knows this job. It only pays if the flag arrives before close-in.
A brim camera looks where the worker looks. The feed is the work, not a tour after the fact.
A vision model trained like a senior in that trade. Framing is not rebar. The skill is specific.
Checked against this job's drawings. The senior knows what this bay is supposed to be.
The miss comes back while the work is still open. The crew can still reach it.
A day on the job
06:40
The crew clips the camera to the brim. Today the trade is framing. The senior for that trade is loaded.
07:15
Work starts. The feed is the gun, the plate, the bay - checked against this job's sheets, not a generic rubric.
11:24
Bay 3 is short on the bottom plate. The super sees it on the desk while the wall is still open.
13:10
Two nails. Minutes. Not a callback after drywall. That is the whole loop.
How it lands
On the job
The model sits on the feed. It checks the trade against the drawings in the moment the work is done - not after the wall is closed and the crew has moved on.
On the worker
The same senior, tighter in the loop: a cue while the fastener is still in the worker's hands. That is the product fully on. We start by proving the senior can see.
Compared to the usual walk
| Check | After close-in | With Prodius |
|---|---|---|
| Who is watching | One senior walking the job, when they have time | A senior on every worker doing that trade |
| When the miss is found | After sheathing, drywall, or the pour | While the fastener is still reachable |
| What gets checked | What is still visible at the walkthrough | The work as it was done, against the drawings |
| Cost to fix | Rework, delay, margin | Minutes, not a callback week |
