A saved research checkpoint is useful only if its specified state can be recovered and checked. This technical reference describes preservation and recovery practices documented through CP106–CP109, followed by clearly labeled future improvements.
Evidence boundary: Historical outcomes are reported from eight retained project reports, provenance records and final delivery receipts. Recovery procedures were not independently re-executed for this reference. This is a research-methodology milestone; it does not establish scientific correctness or demonstrate new physics.
Figure 1. Research checkpoint preservation and recovery verification. AI-generated conceptual illustration for Beyond the Light Barrier. The PASS indicator represents documented CP108/CP109 recovery-verification outcomes, not scientific validation or approval of AR-1.7.
Four operational outcomes
PASS: Positive evidence satisfies the stated check within its declared scope. FAIL: An executed check fails, or a required recovery outcome is not achieved. BLOCKED: A prerequisite or execution restriction prevents completion. NOT TESTED: No completed test is documented for the specified claim. Missing documentation does not prove historical failure. Planned work is not a PASS.
Keep the investigation result, preservation result, recovery result and final durability result separate. Scientific readiness is another assessment. A matching cryptographic checksum provides strong evidence of matching bytes; it does not prove the reasoning in those bytes is correct or by itself authenticate their origin.
Historically documented checks
1. Establish the intended baseline
Identify the exact predecessor and checkpoint state. Verify repository identity, expected history, clean state and the declared file populations before new work. Where publication is required, compare the published checkpoint identities with the intended final state after publication. Successful read access does not establish write authorization or successful publication.
PASS: Required identities, continuity and declared populations agree. FAIL: A required identity or population differs. BLOCKED: Access or a required prerequisite prevents checking. NOT TESTED: The comparison has not been completed.
2. Preserve research completeness and chronology
Inventory the required reports, evidence, metadata and predecessor dependencies. Compare inherited files against their frozen baseline. Keep additions and corrections traceable; retain original findings, defective entries, failed attempts and later corrective addenda. A missing historical manifest field should remain visibly absent rather than acquire an invented verification result.
PASS: All required declared populations are accounted for and verified. FAIL: Required evidence is missing or mismatched. BLOCKED: A required dependency cannot be obtained or examined. NOT TESTED: Completeness has not been checked.
3. Check archive identity and metadata
Record archive identity, size and cryptographic digest. Preserve a raw inventory of payload sizes, digests and required file/directory permissions. Keep the recovery verifier and instructions. Verify the retained destination copy against the expected archive identity. Archive bytes, payload integrity and repository identity answer different questions.
PASS: The specified archive and declared inventory agree. FAIL: A required byte, digest or metadata check disagrees. BLOCKED: The archive or required reference cannot be accessed. NOT TESTED: The stated comparison has not run.
4. Demonstrate a pristine fresh restoration
Extract into a new directory using a method that preserves required permissions. Run the supplied verifier before ordinary repository inspection. Require the successful restoration to pass without permission fixes, inventory edits or repository resets. Retain a failed attempt unchanged and use another fresh directory for a new attempt. After the verifier, separately check the restored repository against the intended checkpoint. Restore required predecessor packages when the checkpoint's closure gates require it.
PASS: The pristine restoration and required follow-up checks pass within their declared scope. FAIL: Extraction, verification or identity checks fail. BLOCKED: Environment or dependency prerequisites prevent completion. NOT TESTED: No fresh restoration has been completed. A repaired restoration does not count as the documented pristine PASS.
5. Complete retention and issue a final receipt
Verify the designated retained copy and preserve its digest companion, instructions and logs. Keep a dated final receipt separate when it records checks performed after immutable package construction. Close durability only after every defined publication, packaging, restoration and retention gate passes. Preserve earlier pending records as the history of their stage.
PASS: All required closure gates have positive evidence and the final receipt identifies the checkpoint and package. FAIL: A required executed gate fails. BLOCKED: A prerequisite prevents closure. NOT TESTED: Required completion evidence or checks remain absent. Durability PASS is limited to those gates; it is not a guarantee against every future failure.
What the checkpoint history actually establishes
| Checkpoint or attempt | Reported outcome and limit |
|---|---|
| CP106 baseline | Later records document a successful fresh restoration of CP106, including repository and declared evidence checks. A prior incomplete archive transfer was retained as a failure before exact recovery of the original transfer. |
| Original CP107 | The authoritative original repository state remains unavailable and unrecovered. Surviving documentation does not restore its missing repository objects. Some external negative searches were owner-reported rather than independently repeated in the later inquiry. |
| CP107-R1 | A distinct re-performance from the verified CP106 baseline. Prior exposure was disclosed; it was not a blinded independent scientific reproduction. Its successful baseline recovery does not recover original CP107. |
| Initial CP106 extraction for CP107-R1 | Failed on a permission mismatch. The failed directory was retained; another fresh extraction preserving permissions passed. The failure did not establish an archive defect. |
| Pre-CP108 operational attempt | A write test was blocked before execution. This did not demonstrate an authentication failure or successful write capability. Later owner publication and read-only verification were separately documented. |
| CP108 | The Phase A report recorded pending durability gates. The later final delivery receipt records durable PASS while the correspondence-ground inquiry remains incomplete — REVISE. |
| CP109 | The Phase A report likewise recorded pending durability. The later receipt records durable PASS, including successful fresh restoration of its retained CP108 recovery dependency. Producer-authority inquiry remains incomplete — REVISE. |
The final receipts were recorded on October 10, 2026 in UTC, which was still October 9 in the project's America/Chicago timezone. Earlier “not begun” and “pending” statements belong to their recorded stages. A later receipt updates operational completion without rewriting those records.
AR-1.7 remains NOT READY. The 36 retained witnesses remained specification-only, unexecuted and unadmitted. Manual documentary controls and separate review phases were not empirical experiments. CP108 and CP109 semantic reviews were performed by the same analyst in later phases. These records establish neither independently reproduced scientific results nor experimental results for this work. They demonstrate no faster-than-light communication, propulsion, wormholes or other new physical phenomenon.
Proposed future improvements
The following are recommendations, not procedures established as completed by these eight historical records:
- Copies separated by location, administration and failure risks, including offline or immutable retention where appropriate.
- Scheduled fresh-restoration drills and drills after changes to archive formats or dependencies.
- A second operator testing recovery from the written instructions, with assistance and deviations recorded.
- Authenticated manifests or receipts and a defined threat model for tampering.
- Explicit retention periods, recovery-time and recovery-point targets, and storage monitoring.
- Complete tool/environment requirements and separately tested portability across supported platforms.
- A documented public-release sanitation check.
Each proposed control needs an adopted scope and acceptance test. Its historical status here is NOT TESTED. Several copies in designated locations do not, by themselves, establish independent failure domains or long-term recoverability.
Practical recording form
For a future run, record the checkpoint and stage, check being performed, expected scope, observed output, operator and time, environment, evidence locator, and PASS/FAIL/BLOCKED/NOT TESTED. Record why a check failed or was blocked and which later gates depend on it. This unified form is a v1.0 recommendation, not a claim that every historical record used the same template.
Source note
The historical claims derive from the CP106 report; CP107-R1 primary report and lost-original provenance record; pre-CP108 durability report; CP108 Phase A report and final delivery receipt; and CP109 Phase A report and final delivery receipt. These are private internal project records. A separate internal crosswalk retains exact source-line references. Their underlying packages, repository objects and verifier logs were not independently examined or re-executed for this reference. This public version deliberately omits private identifiers and infrastructure details.
