Sample data

This repository does not exist. It is part of the preview's fictional dataset, present so this page's every state — badge, waivers, allocations, coverage — can be seen and tested before a real project adopts. A production build refuses this data outright.

Semantic diffs for spreadsheets — cell-level changes, formula moves, and sheet renames, as a library.

Conversion to Apache-2.0

Every released version converts on its own fourth anniversary — the licence is not a single clock, and a project that keeps releasing keeps a rolling four-year window rather than reaching one cliff.

Per-release-year conversion dates for this repository

Versions released in Convert to Apache-2.0 during
2026 2030

The licence version itself (PurposeSource-1.0) converts on 2030-09-01, computed from its publication date rather than stored.

Organisations covered for this repository

Impact Shares

5 holders. Largest share 44% · median 15%. Algorithm version: pp-v0 (sample)

below the published floor — points and percentiles only, no currency figure. Impact Shares direct a pool towards cause categories; they never pay a contributor. The share figures are coarse on purpose — the display gate exists so a small share is never dressed up as an income, and the algorithm version is printed because the shares mean nothing without it.

Public benefit produced

Nothing has been allocated to this repository's pool yet. No intake is recorded against it either.

Where this project's pool routes

  • Research project-default

Categories come from the published menu, never from free text. A project that sets none inherits the steward default; either way the routing is visible here and in the ledger rows.

Fee waivers

Waivers granted for this repository. 0 voided inside the cooling window and are omitted — a voided waiver never vested anything.

Proving coverage for this repository

There is no live coverage endpoint at this phase. The proof of coverage is the published, signed entitlement record plus this site's verification page: fetch /v1/entitlements/{companyId}.jws, check its ES256 signature against /jwks.json, and read the lane, scope and period. The computed endpoint activates later with no schema change, so a client written against those documents today keeps working.

Badge embed kit

Sample data

This repository is part of the sample dataset, so the snippets below point at a node id that no real repository holds. They are here to show the exact shape of what a real administrator copies.

The badge reads a published artifact through the shields.io endpoint protocol, so it reflects the registry within the published propagation bound and needs no build step in your repository.

The endpoint itself

https://api.purposesource.org/badge/R_kgDOSMPL0005.json

verify only at purposesource.org/verify — the badge asserts registration, and a certificate proves it. Any other address offering to verify a Purpose Source certificate is not ours, and the one above is the only address printed on any artifact we issue.

Contributors: claim your impact. A merged contribution to helvetica-tools/sheet-diff can carry an attributed, verifiable record once the claim flow exists. The only channels that will ever invite you are this page, the badge, and links in the repository itself — no email campaigns, no unsolicited messages.
