01
Register source evidence
Original files are verified, hashed, and staged in R2 before the case references them.
Evidence-led land administration
A land-record decision should be traceable to its source.
Follow every claim from original evidence, through deterministic checks and maker–checker review, to a commitment that an independent verifier can recompute.

One case · complete chain of custody
Everyone sees the same evidence. Each role does one clear job.
The interface follows the record lifecycle, while server-side authorization prevents a role from quietly stepping outside its responsibility.02
Locate every assertion
AI proposes source-linked facts with page coordinates and marks uncertain readings instead of guessing.
03
Reconcile deterministically
Rules compare survey numbers, extents, chronology, exclusive claims, and tenant rights.
04
Decide with separation
A maker prepares the change. A different checker independently approves or rejects it.
Built for review, not black-box automation
The model can propose a reading. It cannot make the legal decision.
Every extracted field keeps its source location and provenance. Ambiguous handwriting remains uncertain. Corrections preserve the raw text and require a reason. Legal restrictions remain hard stops for the appropriate process.
- Raw and normalized values stay separate
- Effective dates control chronology—not upload time
- Maker and checker must be different identities

Responsibility by design
The application changes with the person who signs in.
Navigation, guidance, and available actions are scoped to the verified Clerk role and jurisdiction.Own the application
Start a request, attach source records, and see what has entered review.
Prepare reliable evidence
Receive files, validate metadata, run extraction, and hand off a complete dossier.
Build the source-grounded proposal
Correct OCR with reasons, address permitted discrepancies, and freeze the facts.
Attest physical geometry
Confirm shared boundaries before an amalgamation can move forward.
Make the independent decision
Review a frozen proposal and approve only when every server-side gate passes.
Verify without changing records
Recompute commitments, check freshness, and confirm registered evidence digests.
