Plancheck

A deployment-document intake agent that knows which of its own answers to trust.

Prepared by Neel Barmecha For Forward Deployed · AI Consultant Status Proof of concept

Infrastructure projects run on paper. Permits, notices to proceed, interconnection agreements, inspection reports — each one read by a person and hand-keyed into the system of record. It is slow, and it fails quietly: a transposed permit number or a wrong expiration date surfaces as a stalled build six weeks later.

Extraction is the easy part of fixing that. Any current model reads a permit. What decides whether anyone keeps using the system is whether it knows which of its own answers to trust — and hands the rest to a person before they reach the record.

01 · Extract
Every field returns a value, a calibrated confidence, and the verbatim span it came from. Nothing ungrounded.
02 · Verify
A second, independent pass audits each value against the source. This is what catches confident-and-wrong.
03 · Decide
Clears its bar and verifies, it posts. Anything else goes to the exception queue. High-stakes fields carry a stricter bar.

Modelled, not measured. The figures move with the assumptions above and with the calibration. The last line is the one that matters in a review: throughput bought by loosening the bar is paid for in errors nobody catches.

Turn the verification pass off and watch the fee field. It posts $1,240.00 — confidently, plausibly, and wrong. The document's total is $2,225.00; the extraction took the first line item. No confidence score catches that, because the model is not uncertain. Only a second pass reading the source is.

That case is seeded deliberately in this run and should be read as an illustration, not a failure caught in the wild. Whether a particular model misreads a particular fee table varies run to run, which is precisely the argument: a pipeline that only works when the model happens to be careful is not a pipeline. Extraction is a commodity. Knowing what not to trust is the product.

Week 01

Map the paper

Sit with the people doing intake today and take the real inventory.

  • Document types and volumes
  • Fields each one feeds, and the object they land on
  • Which errors have actually cost a project

Week 02

Calibrate on their corpus

Run a labelled sample and set the bars against measured behaviour.

  • Per-field confidence bars
  • High-stakes list agreed with the business
  • Precision and review-load curve signed off

Week 03

Wire it in, hand it over

Into the system of record, with the queue where reviewers already work.

  • JSON to record integration
  • Queue routing and audit trail
  • Drift monitoring and runbook
Runs live or offline — python3 plancheck.py sample_permit.txt · --no-verify to see what escapes · --sweep for the calibration curve.
