Editorial review of private implementation and internal acceptance material; not an external security audit.

  1. 1

    What was examined

    A bounded reconstruction implementation, separate oracle and engine paths, and their internal comparison and acceptance records.

  2. 2

    How it was reviewed

    Review of implementation scope, continuity and state-commitment checks, differential outcomes and the limits recorded with acceptance. The website does not rerun these private checks.

  3. 3

    What the review supports

    The reviewed material supports the limited claim that local reconstruction and comparison foundations are implemented. Agreement, refusal and disagreement are distinct observations; none is a blanket production-readiness verdict.

Claim ledger

Every public claim in this section, with the status the evidence supports, its basis and its limit.

Bounded reconstruction of a preserved history is implemented locallyProven todayInternal implementation-scope reviewApplies to the examined historical baseline
Two independent paths compare without default authorityProven todayDifferential review of oracle and engine outcomesSeparation alone does not exclude shared assumptions
Continuity and state-commitment checks are part of the local scopeProven todayInternal implementation-scope reviewNot a general database, a live network or unrestricted replay
Shared refusal classes and the one genuine asymmetric refusal are classified end to endProven todayDifferential tribunal: both paths raise the paired class at the same unit; the sequence frontier is the one asymmetric surface reachable between themBetween two correct implementations no other asymmetric surface can occur without mutating a path
Every other asymmetric surface is classified only by synthetic observationQualifiedComparator-only table, executed from a hostile corpus, proved disjoint from and total with the end-to-end tableQualified by construction: not input-reachable, and never converted into a winner

What the evidence does not establish

  • No distributed network, consensus finality, production throughput or financial-service availability is established by this evidence.
  • A recorded acceptance applies to its examined scope and historical baseline. It does not certify the latest development branch.
  • Asymmetric surfaces beyond the sequence frontier are classified by synthetic observation only and stay qualified by construction. A difference must not be silently converted into a winner or a conclusive diagnosis.
  • Internal reviews, including agent-assisted reviews, are not independent external audits.
  • A digest identifies bytes; it does not by itself prove that a process ran correctly.

Public reproducibility

The full source and private reproduction package are not public. This card is an explanatory scope note, not a downloadable proof or a publicly reproducible verification. The linked illustration uses synthetic data only.

Revision conditions

Re-review when the implementation baseline, accepted scope, known limits or availability changes. A withdrawn claim must also be removed from search and derived presentations.
