Research & methodologyAn evidence architecture
An evidence architecture
for ecological obligations.
This research room documents the problem framing, ontology, amendment logic, evaluation design, spatial intelligence architecture, and explicit limits behind VerdaTrace.
Research positionMissing evidence is a workflow state—not a legal conclusion.
01
Problem statement
The obligation lifecycle is structurally fragmented.
Environmental commitments begin as prose, change through later approvals, and are verified through heterogeneous evidence. Most workflows preserve the documents but not the relationships among duties, revisions, evidence, geography, and decisions.
Temporal problem
Later amendments may replace only one condition while preserving the remainder of the earlier approval.
Evidence problem
Proof exists in maps, notifications, reports, photos, and field observations with uneven integrity metadata.
02
Obligation ontology01 02 03 04 05 06 07 08
A shared grammar for what must happen—and what proves it.
The ontology separates source-grounded facts from later assessments. This makes extraction measurable, revision logic deterministic, and human disagreement visible.
Actor
Who is responsible for the action or evidence
Action
What must be done, maintained, submitted, or verified
Object
The parcel, habitat, report, fund, or asset affected
Measure
Area, quantity, unit, threshold, or duration
Time
Deadline, recurrence, or effective date
Place
Named geography or referenced spatial artifact
Source
Document, page, clause, and immutable fingerprint
State
Current, superseded, due, evidenced, or review required
Obligation=
actor + action + object + measure + time + place + source + state03
System method
Probabilistic reading, deterministic boundaries.
VerdaTrace Intelligence handles multimodal document understanding and structured extraction. Rules handle the conditions where a plausible automated answer is not sufficient.
Model layer
Multimodal document interpretation
Read digital records, scans, and field images, preserve visible identifiers, and return structured obligation candidates.

Schema and revision controls
Reject uncited outputs, normalize fields, connect replacement clauses, and prevent simultaneous active states.

Demonstration case15 May 2025 03 September 2025
Proposal FP/KA/ROAD/7440/2014
The case concerns forest land diversion for an approach road in Ballari district, Karnataka. It was selected because a later public amendment changes the ecological treatment of a 9.54-hectare parcel, creating a clear test of temporal reasoning.
Final approval
The approval contains project conditions including compensatory afforestation treatment for the identified parcel.
Open public PDFreplacement condition
Amendment
The parcel is instead to be conserved for natural growth and wildlife habitat; unchanged conditions continue.
Open public PDFProposal and spatial record indexThe source portal provides project records and a KML entry point. The demo does not invent the amended parcel boundary when the precise geometry is absent from the review set.

Evaluation design
Measured claims only.
The bundled gold set contains 24 prepared obligation labels. Consultant review remains outstanding, so precision and recall are deliberately unpublished.

Geospatial intelligence architectureFoundation Integration ready Calibration track
Evidence layers without false precision.
VerdaTrace anchors spatial analysis to documented geometry and treats missing boundaries as evidence gaps. Remote-sensing layers enter operational workflows through reproducible methods, project-level calibration, and expert-reviewed thresholds.
Source geometry
KML/GeoJSON validation, area discrepancy flags, and explicit gaps.
Dynamic World
Ten-metre land-cover probabilities, temporal baselines, and interpretable change signals.
AlphaEarth
Annual landscape embeddings for site similarity, anomaly ranking, and sparse-label modelling.
07
Limitations & safeguardsNo legal determination No invented geography No unreviewed benchmark claim
What the system does not claim.
Evidence gaps are triage signals. They are not proof of non-compliance, negligence, or ecological harm.
Approximate locations are labelled. Missing parcels remain missing until a valid spatial artifact is supplied.
Prepared labels are not presented as expert-validated accuracy until an external reviewer confirms them.
