Entitlement holders

Entitlement binds to the holder, not the parcel. Apportionment is by basis points and survives a change of parcel mix.

Soil sampling

Sampling progress across the holding. A parcel is the unit of record — cores are pulled within it, not within an arbitrary grid.

Field capture. Everything here is provenance the file itself will not carry — record it now or lose it.

New core

GPS latitude * GPS longitude * Parcel (LPID) * Sample depth * Core ID * Collection date * Collected by * Laboratory *

Depth other than 0–50 cm will be flagged at import: the record's basis is fixed-depth 0–50 cm and mixing bases silently breaks comparability.

Notes

Site / core photo Tap or drop an image. Held with the core until sync — the photo is provenance, not decoration.

Import lab results

Map the lab's columns onto the record's fields, see what fails before anything is written, then import the rows that pass.

Warnings do not block an import. A row with a missing optional value is still a true observation, and rejecting the batch to protect a schema loses real data. Only rows that fail structurally are held back.

Carbon stock

Density by parcel on the fixed 0–50 cm basis, against the round 1 baseline. Colour encodes tC/ha on a single hue — the scale is sequential, so darker is strictly more.

Basis and comparability

Import a livestock registry extract

Format is detected from content, not filename. The parser reads the record-type letter, builds residency intervals from movement rows, and reports unresolved references rather than rejecting them.

Herd

Animals currently on the holding, as resolved from the most recent registry extract. A herd is a snapshot, not a roll — an animal that has left is absent, not marked departed.

Passport

Verification

A passport is only as strong as the weakest link above. Nothing here is a claim about the animal — it is a claim about the evidence for the animal.

Identity

Provenance

Add an animal

Manual entry is the exception. An animal that exists in the registry should arrive by extract — typing it in by hand creates a record the scheme cannot corroborate.

The check digit is not validated — the algorithm is unconfirmed, and on anonymised files the digit is a pseudonym that would never pass. See Registry extract.

Residency and event chain

What the extract does not say

Entitlement and issuance

What the round actually entitles the holding to, and why the figure is smaller than the measurement.

Certified chain satisfied

From measurement to issuance

Land token asymmetry rule

Only a land token with an unbroken certified chain back to an actual soil measurement event may mint. One parcel this round has no physical measurement, so its contribution is excluded in full rather than discounted.

Excluded: NO2547-2201 · 9.8 ha permanent grassland
Reason: Modelled remote SOC product, depth-extrapolated 0–30 → 0–50 cm. No coring event this round.
Effect: 43.159 tCO₂e removed at 100%
Recoverable: Yes — a coring round on this parcel restores the chain.

Enforced in contract, not in the interface. The payload carries certified_chain.satisfied; the smart contract refuses to mint against an affected quantity regardless of what any dashboard displays.

Holder apportionment

Legal names never cross the boundary. Beyond it a holder is a stable pseudonymous reference, so Scotcoin can attribute tokens across rounds without learning who anyone is.

40 tCO₂e deferred. The holding is not yet at net zero, so the first tranche is held back pending a round evidencing a net position at or below zero. Review 2 March 2027.

Request issuance

Assembles the payload that crosses to Scotcoin. Everything shown here is derived from the signed record — nothing is entered by hand at this stage.

Field app

The mobile journey as artboards, so it can be reviewed alongside the console. Offline-first: the phone is the one place in this system that cannot assume a network.

What crosses the boundary

WP1 holds the record on the permissioned ledger. WP3 receives a projection of it. This screen exists so the split is auditable rather than assumed.

Crosses to Scotcoin

Signed payload

Platform: Hyperledger Fabric · network agorin-poc · channel agorin · chaincode dpp
Issuer: Signed by a WP1 Fabric node identity, pinned by Scotcoin against the agreed allowlist
Holder identity: urn:ubl:holder-ref:… plus DID where issued. There is no address field and no wallet.
Commitment: Granular data committed by hash, RFC 8785 canonical JSON, disclosed only under an inclusion proof
Parcel set: Merkle root over the parcel collection, so a single parcel can be proven without revealing the rest

Terminology. The holding and transfer mechanism is deliberately not called a wallet, at Scotcoin's request. The schema has no such field; this interface follows it.
