Case study
Lasting Ground: turning fragmented public context into a readable packet.
A source-backed property review system built around validation gates, evidence scoring, review queues, support-depth rules, and printable artifacts.
A packet system with source checks before language.
Lasting Ground is presented as a review system: source lanes, support-depth scoring, cautious claim language, and a generated sample packet.
The problem
Property context can be scattered across public layers, local boards, source registers, town pages, maps, and records. The product challenge is to make that context readable without overstating what the sources support.
System decisions
Evidence before language
The packet language is downstream of source-lane validation and evidence scoring.
Uncertainty as a product state
Missing or stale lanes become visible warnings and review actions instead of hidden gaps.
Artifacts people can inspect
The system outputs a sample PDF, source register, validation gate, and coverage-backed examples.
Code worth inspecting
- evidence_scoring.py — scores source lanes by authority, freshness, support, and blockers.
- packet_composer.py — composes packet sections from validation output.
- source_lane_validation.py — validates lane status and support depth.
- CI workflow — runs tests and coverage.
Capabilities demonstrated
Evidence architecture plus readable delivery.
Full-stack workflow design, cautious claim handling, source-backed product architecture, validation gates, generated artifacts, and technical communication for complex domains.
