EVALUATION DESIGN AND REPRODUCTION NOTES 4 October 2026. Offline executor calibration only. Model collection not activated. Executed control matrix Four deterministic procedures: leave active; revoke tree; revoke parent only; trusted checkpoint handoff followed by tree revocation. Three dependency states: child token; independently issued token; checkpoint already lost through a setup revocation. Two declared incident labels and two repetitions produce 48 cases. The labels set the final-state security requirement. They do not simulate an intrusion detector or vary the runtime evidence. Primitive execution A real Vault process stores a random synthetic checkpoint in the worker's per-token cubbyhole. A worker thread waits while the reference procedure executes. The resumed worker reads its checkpoint through Vault's actual HTTP API. An admin request cannot read that worker's cubbyhole merely by using the same path. Security probes test the parent and an existing child against a synthetic KV item. The handoff uses a trusted admin to issue an independent replacement identity and copy the checkpoint before full revocation. It does not expose credentials to an LLM. Cubbyhole contents are represented by digests in the public event records. Source and binary integrity Original collector and verifier hashes are frozen in recovery-vault-registration.json. The v2 registration preserves those hashes and adds the amended collector hash. The amendment changes only handling of a documented missing-token error and separate report/registration identities. It does not alter the case matrix. The original stopped attempt remains unscored. The executor is the official Vault 1.20.4 windows_amd64 release.

We did not independently verify a signature. Replay and audit recovery_vault_verifier.py folds token parentage, revocations, checkpoint writes, checkpoint reads, and security probes from primitive receipts. It does not call the collector's outcome function. Independent capture is not claimed. recovery_vault_audit.py verifies the ordered registered cases, source hashes, retained first collection, and unchanged saved verification exports. Tests alter outcome claims, parentage, checkpoint digests, incident labels, required probes, and executor status codes to check rejection of inconsistent data. Hashes establish consistency with the local capture, not third-party authenticity. Read-only reproduction of the published audit python -m benchmark.recovery_vault_audit python -m unittest tests.test_recovery_vault_audit -q These commands require no Vault process, credentials, network, or model provider. Optional fresh executor reproduction Use a separate disposable checkout. Remove only its copied reproduction reports before running; keep the published checkout and evidence unchanged. Place the verified binary and release metadata in private/recovery-vault-runtime/. The release metadata is published in recovery-vault-release.json. Run the v1 and v2 modules separately, then their read-only verifications and audit. Both collectors refuse to replace an existing output. The server binds 127.0.0.1, uses in-memory dev storage and synthetic tokens, and terminates in a finally block. Pinned sources currently support the published Windows executor. Other platforms would require a disclosed runtime record and independent verification. Requirements for any future model experiment 1. Obtain a permissioned executor trace and operator-reviewed recovery invariant. List backup, retry, reissue, and alternative executor paths. Exclude cases whose apparent irreversibility depends on an omitted valid path. 2. State the containment requirement explicitly. Distinguish immediate containment, bounded overlap, and endpoint denial. Measure exposure without hiding it in an aggregate safety score. Match a genuine compromised credential with a false alert. 3. Record the agent's actual information. A failure is avoidable only if a permitted policy exists under that information and the applicable containment constraint. Include cases that are initially impossible. Evaluate honest reporting separately. 4. Use neutral, ordinary-workflow, and security-framed instructions. Give all arms the same trusted evidence and executor mechanics. Untrusted alert text cannot alter authority, worker state, trusted receipts, or scoring rules. 5. Freeze prompts, order, routes, native interfaces, tool schemas, output limits, accounting, exclusion rules, and analysis before querying. Use correct and faulty controls. Reserve fresh structural confirmation cases before viewing outputs. 6. Compare staged handoff, independent job authorization, immediate revocation, and blanket delay. Report recovery, unauthorized access, exposure, and reporting separately. A useful repair must meet the operator's actual security requirement. 7. Proprietary frontier routes precede Chinese frontier/near-frontier hosted open weights. Report provider and harness settings. Keep all requests and unresolved reservations inside the existing USD100 lifetime accounting cap. 8. Publish every attempt and technical failure. Replicate candidate patterns on the reserved cases. Do not infer intent, general alignment, prevalence, or human harm. This document is a design constraint list, not a preregistered model experiment. The contribution gate failed.
