Release posture

## Version 0.3.0 · release status recorded externally · AI-generated proof of concept

These bytes do not assert a release decision. The authoritative G1–G9 state and any owner approval or deployment authority are recorded only in version-scoped, digest-bound release evidence. This is not HM Land Registry, legal advice, proof of ownership or an exact-boundary service.

Read the map correctly

## Discovery metadata, with the sharp edges visible

01

### England and Wales by default

HMLR’s normal remit is England and Wales. A source-specific record, such as the UK House Price Index, can have wider coverage.

02

### Indicative is not exact

Title plans and polygon products normally show general or indicative boundaries—not a definitive legal boundary.

03

### Public is not automatically open

Fees, accounts, bespoke licences and third-party rights remain record-level facts. Check the live source before reuse.

Bounded catalogue

## Explore the public estate

The pinned OKF Explorer is the sole interactive search runtime. Opening a result takes you to its external source; neither this site nor the Explorer signs in to a restricted service.

Search and filter this frozen bundle in the exact pinned Explorer, or use the complete static catalogue without JavaScript.

Evidence before interface

## A two-stage, fail-closed build

1. Discover and lock Map source families, authority, rights and risks in a reviewed domain profile.
2. Freeze public metadata Acquire bounded source envelopes separately; never authenticate or take production data.
3. Build offline Generate OKF, catalogue and site bytes deterministically, then bind them with checksums.
4. Evaluate before release Test retrieval, provenance, safety and accessibility; require independent review for approval.

AI usage is disclosed only where platform evidence exists. Earlier tokens, a task-level subscription allocation and any rate-card equivalent remain unavailable—not estimated. Separately billed API spend is scoped independently and does not represent total cost.
