Heartcode Experimental Action Evidence v0.1

Eight original synthetic fixtures for an experimental action-submission boundary. GitHub is canonical: release directory. Hugging Face is a distribution copy of these exact files.

What this measures

A host-owned test grant allows exactly one bound RESET proposal. Missing, expired, revoked, stale, mismatched or unverifiable authority blocks submission to a fake environment. Expected records include deterministic decisions, reason codes, execution outcomes and integrity hashes. These are software regression outcomes, not independent human labels or the eight conversational Heartcode rule verdicts.

The ARC-shaped fixture names a synthetic session for ls20. No upstream ARC agent, game, model, provider or live scorecard was run. No ARC endorsement, conformance, task-performance improvement or general safety conclusion is established.

Files and schema

• —fixtures.jsonl: eight rows with caseid, schemaversion, synthetic, input and input_sha256. Input contains the proposal, separate trustedTestAuthority, fixed time and host bindings. The test host provides authority; copying this JSON grants no permission.
• —expected.jsonl: caseid, inputsha256, environment_calls and evidence. Evidence contains schemaVersion, policy, observedAt, proposal, grant, decision, reason, execution, receiptId, submissionsReserved and artifactSha256.
• —manifest.json: release identity, generation source revision and SHA-256 of each listed file's exact UTF-8 bytes (excluding the manifest itself).
• —verify.mjs and verify.test.mjs: standalone integrity/consistency verifier and tests.
• —LICENSE: MIT terms scoped to this directory's newly authored material.

A grant may be null in evidence if host binding checks fail before authority is resolved. Expected decisions are for policy experimental-action-boundary.v0.1, not an open-ended authorization policy.

Verify offline

Requires Node.js 22 or newer; no package installation, network, model or GPU.

node verify.mjs
node --test verify.test.mjs

The verifier checks the file manifest, record identity, input/evidence hashes and declared call/outcome consistency. It does not independently re-run the private evaluator or authenticate the issuer. Full regeneration uses the pinned Validator Master generation source recorded in the manifest and requires access to that implementation. Hashes are unkeyed integrity checks, not signatures.

Provenance, license and privacy

All rows were newly authored with Codex for Heartcode Protocol on 2026-09-15. Identifiers, authority, receipts and timestamps are synthetic. There are no user conversations, provider responses, credentials, payment data or imported ARC game assets. The MIT license covers this directory only; it does not relicense the protocol specification, trademarks, third-party artifacts or Validator Master.

Limitations and intended use

Use for regression testing evidence importers and studying fail-closed semantics. Eight hand-designed cases provide narrow coverage. There is no independent annotation, measured benchmark accuracy, multilingual coverage, durable authority store or production authentication system. The in-memory implementation's replay state is process-local and must not be treated as durable security enforcement.

Version and sync policy

Submit corrections to the public GitHub repository first. Publish a new version when fixtures, policy or expected outputs change; preserve old releases. HF copies must match the manifest. Verify downloads after upload and retain the HF revision. No paid inference service or duplicated Validator Master application is needed.
