# Changelog — evidence-backed-brief

## [0.1.0] — unreleased (local candidate)

### Added
- First version of the protocol: contract (`protocol.yaml`), skill (`SKILL.md`),
  README (the ten questions), a claim-typing reference, brief and receipt
  templates, a worked example that doubles as the test fixture, structural test
  cases with positive, failure/boundary, and discrimination cases, the
  `ebb-core-v1` three-arm eval task set (design only, not executed), and four
  adapters (generic-chat copy-and-run, Claude, Codex, local-agent).

### Status
- Protocol assurance: set by the pack `RECEIPT.json` after `verify-all`.
- Productivity evidence: `NO_IMPACT_EVIDENCE` — no evaluation has been run.
