Every metre of this road has a status.
Nobody set them. Each of the 14,000 cells on this road takes its colour from the inspections raised against it. Approve one, and the road changes underneath you.

Nobody sets a status
A cell is not a field anyone can edit. Its state is computed, every time it is drawn, from the inspections covering it — and the worst case wins, so a failed sixty-metre stretch can never be hidden by the approvals on either side of it.
That is the whole map above: four states, 306 records.
- Approved
- 303 inspections signed off behind the working front, back to 120+000.
- Awaiting approval
- Inspection 352 — Submitted, 120 m of GSB on the LHS, 130+300–130+420.Inspection 357 — Raised, 280 m of GSB on the RHS, 130+520–130+800.
- Rejected
- Inspection 341 — 60 m of GSB on the LHS, 130+180–130+240.
- Not assigned
- Everything ahead of the front. No inspection has claimed it yet.
The evidence comes first
An inspection carries the tests its layer’s frequency plan requires. It cannot go to an approver until every due test has evidence against it — a field sheet read off the page, or a lab result keyed in. The moment the last one lands, it submits itself. There is no override.

What a failure looks like
130+180 → 130+240 · GSB · LHS · 60 m
Six pits of field dry density by sand replacement, read off the photographed sheet and averaged by the same arithmetic the sheet prints. It came out under the line, so the inspection could not close and 60 m of sub-base went red on the map — and stayed red until the stretch was re-compacted and re-tested.
96.78%
Required > 98% · MoRT&H Cl. 401.3.2
“Compaction 96.78% — below specified 98%. Re-compact and re-test.”
Two ways in
The console
For the people on the road and the people answering for it.
Seven destinations: an overview that leads with what needs attention, the road itself, every inspection, every test behind them, a work queue ordered by what is latest, reports on throughput and rework, and administration. It reads on a phone in the sun and on a desk in the site office.
The REST API
For the system that already runs the contract.
The same read model over HTTP: cursor pagination, idempotency keys on every write, signed webhooks on every state change. An ERP can raise an inspection, collect its results and reconcile the register without anyone opening a browser.
