+## 1.0.0

+- Initial Protocol-Commons release with versioned Commons schemas, shared primitives, and example vectors under `schemas/v1.0.0` and `examples/v1.0.0`
+- Introduced the canonical Commons verb set and request/receipt validation model for cross-runtime interoperability
+- Established the historical pinned release line that `v1.1.0` now extends as the current in-repo schema family

+# Contributing — Protocol Commons
+
+Protocol-Commons contributions must be small, traceable, and validation-complete.
+
+## Pull Request Spine
+
+Every PR should:
+
+1. Open from a focused branch for one change set
+2. Explain the semantic, schema, or documentation impact
+3. Include schema/example updates together when contracts change
+4. Pass the required validation commands before review
+5. Update release notes when the visible contract changes
+
+## Commit Convention
+
+Use a clear imperative subject line. Prefer conventional-style prefixes when they fit, for example:
+
+- `docs: tighten README contract language`
+- `feat: add new commons verb schema family`
+- `fix: correct receipt validation example`
+
+## Required Checks
+
+Run the canonical validation command before opening a PR:
+
+```bash
+npm install
+npm run validate
+```
+
+Run additional checks when packaging behavior changes:
+
+```bash
+npm run test:smoke:import
+npm run test:smoke:pack
+```
+
+## When Schemas Change
+
+If you change a schema or semantic contract, you must also:
+
+- Add or update matching examples/tests
+- Preserve immutability of published version directories unless the change is explicitly historical documentation only
+- Review `SCHEMAS.md` and `SPEC.md` for versioning implications
+- Update `CHANGELOG.md` when the externally visible contract changes
+- Update `RESOLUTION.md`, provenance, or checksum artifacts if the release process requires it
+
+## Versioning Expectations
+
+- Treat published release lines as append-only history
+- Use a new version directory for semantic changes
+- Keep `v1.1.0` documented as the current in-repo line until a newer line is intentionally introduced
+
+## Review Standard
+
+A contribution is ready for review when a maintainer can understand the intent quickly, reproduce validation locally, and see exact schema/example/doc alignment without extra interpretation.
