Northing

Ver 1.0 // United Kingdom // Record of Effort

REF: 56.8121° N, 5.0035° W

STATE: READY

01. Primary Functions

[AUDIT] Ledger Ingestion: Northing performs a post-hoc audit of the local device health ledger. We ingest raw coordinate samples and barometric pressure data to ensure an un-smoothed record of effort.
[FIX] Coordinate Verification: Verify summit arrival by cross-referencing raw ledger samples against a 100-metre technical tolerance.
[GAIN] Vertical Delta: Absolute gain is calculated via the delta of atmospheric pressure samples, bypassing standard consumer-grade estimation.

Operating Rules

AGENCY: Northing never replaces judgment. It supports it. Users are responsible for their own safety and navigation.

FACTS OVER FEELINGS: No motivational copy. No "well done." Effort is recorded without dilution or praise.

THE FRAME: We provide the start and end. We never provide the route. The mountain dictates the line.

NO SAFETY THEATRE: No colour-coded danger states. No false confidence scores. The user assesses the risk.

DURABILITY: No novelty features. If it dates the product in five years, it is rejected.

SOVEREIGNTY: Your data is yours. No feeds, no likes, no performance for others.

Technical Documentation

Annex A: Statement of Sovereignty

Northing operates on a strict Local-First architecture with a Zero-Cloud default. All ledger data resides solely on the local device. No telemetry, social graph ingestion, or external server synchronisation occurs without explicit user export action.

Annex B: Audit Protocol

Coordinate verification mandates a raw ledger sample within a 100-metre horizontal tolerance of the target summit. Vertical accumulation is calculated via absolute barometric delta, rejecting standard GPS vertical estimation to minimise atmospheric drift errors.

Annex C: Ledger Index

Geographic scope is restricted to Great Britain (England, Scotland, Wales). The internal database comprises 282 Munros, 214 Wainwrights, and 1,550 Marilyns. Ireland and Northern Ireland are strictly excluded from the current build.
