ENGINEERING EVIDENCE
August 6, 2026 PASS
This checkpoint predates the final Zora RAG v1.0.0 release and is presented as evidence for the retrieval and governed-history claims in the case study.

Mean Reciprocal Rank
In practical terms: when Zora was tested against questions with known answers, the correct evidence was retrieved first 98% of the time and appeared within the top three results every time.
Unknown-content negative case
PASS
Overall retrieval requirements
PASS
Evaluation strength was preserved. Maximum acceptable rank remained 1, minimum top score remained 0.35, and retrieval thresholds were not weakened to obtain the result.

04 EVIDENCE SCOPE
Retrieval Quality
The recorded metrics substantiate the retrieval-performance claims shown on the main Evidence page.
Governed Behavior
The checkpoint verifies public-interface acceptance, privacy protection, unsupported-question rejection, and bounded behavior.
Known-Good State
The checkpoint records a reproducible engineering state with tests, acceptance results, and explicit limitations.
This is not an independent audit, certification, or the final v1.0.0 release record.
05 SOURCE RECORD
This page is derived from the original machine-readable and human-readable August 6 engineering checkpoint. Private hostnames, filesystem paths, sensor identifiers, rollback markers, backup paths, and other implementation-specific details have been intentionally omitted from the public portfolio.
