Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# packages/shared/contracts — shared wire contracts (JSON Schema)

Source-of-truth schemas for cross-service/SDK wire shapes:
`schemas/policy.schema.json` covers tenant policy and
`schemas/practice.schema.json` covers practice-library records.

## Layout

- `schemas/policy.schema.json` — JSON Schema 2020-12 for the tenant policy object (required: version, runtime_mode, fail_policy, providers, limits, retention, optimizers, telemetry, sdk)
- `schemas/practice.schema.json` — strict JSON Schema 2020-12 for one practice record; unknown fields and enums fail closed
- `schemas/adapter-conformance.schema.json` — static Pi/Claude/Vercel AI SDK/Eve/
  Mastra contract-record shape; `evidence: static_contract_only` explicitly
  denies executable proof
- `schemas/canonical-span.schema.json` — `caveman.span.v1`, the normalized
  evidence-plane span shared by trace intelligence and replay
- `schemas/agent-run-receipt.schema.json` — `caveman.agent.run-receipt.v1`,
  content-blind per-run SDK economic receipt. It is a shared wire shape, not an
  anonymous CLI event and not a signed verified-savings receipt. Retry events
  carry reserved spend, measured spend, and measurement basis

How to install

The exact contents, by fingerprint

mdr add juliusbrussee/caveman/packages/shared/contracts/CLAUDE.md@sha256:6a47877f9279f409

The line at the top of this page pins the label git:20260925.489940d, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
