About RetroGrid
RetroGrid makes system updates predictable.
Pick a Universe Day.
Test. Validate. Deploy to that day when ready.
Repository history is preserved with clear evidence and auditability.
What We Do
- Capture what was observable on the public internet at specific points in time.
- Record how it was obtained.
- Provide evidence that what you see today matches what was seen then.
- Archive these states forever.
- Create deterministic, defensible reconstructions of past Operating System states, one day at a time.
What We Don't Do
- Interpret publisher intent with our historical archive.
- Correct observed flaws in the state of our historical archive.
- Make claims about other observations made by other parties.
Without Systems Like RetroGrid
Reproducible Update Failure. Without preserved historical states:
- It's impossible to predict the result of testing and updates.
- Past environments cannot be rebuilt.
- Regression analysis becomes guesswork.
- "Known good" baselines don't exist.
- Complex or in-house solutions are common.
Audit Failure Risk. Without a trusted, third-party historical record:
- Claims about past system states become non-verifiable.
- Audits rely on testimony instead of verifiable evidence.
- Public evidence decays and disappears as upstream sources are updated or go offline entirely.
- It becomes difficult to meet the burden of historicity in a manner trusted by third parties.
Evidentiary Decay Over Time.
- Public repos change, disappear, and become corrupted.
- Provenance collapses silently as evidence disappears.
- Disputes become unresolvable.
- Timelines cannot be reconstructed.
RetroGrid Provides Support For
- Auditors.
- Investigators.
- Engineers.
- Organizations that need trustworthy access to historical software states for:
- Compliance.
- Forensics.
- Reproducible builds.
- Incident response.
- Long-term digital preservation.
Current Status
As a new project, RetroGrid does not yet provide:- Cryptographically anchored immutability guarantees
- Third-party attestation or certification
- Formal compliance mappings (ISO, SOC-2, NIST, etc.)
- Contractual SLAs or policy commitments
- Audit opinions or compliance assertions
