Evidence-status rules

The resource distinguishes four evidence classes. Here, evidence status describes what a source can support, not a score for how sophisticated its formatting appears.

Status	Meaning	Appropriate public use
Verified verbatim record	Wording checked against an original export, screenshot or authoritative transcript	May be quoted with a source note
Conversation-history reconstruction	A recovered summary or wording that has not been checked against the original record	Paraphrase; do not present as a quotation
Frozen project evidence	Manuscript, output, figure, log, handover or other version-controlled project artefact	May support claims within its actual evidential scope
Current interpretation	A later claim about what an episode demonstrates	Label as interpretation and keep it narrower than the underlying evidence

Why the distinction matters

A clean narrative written after the event can make contribution appear more certain than it was.

A version history can show that a sentence changed without establishing why it changed. A transcript can show that someone claimed to have performed a check without proving that the check was executed correctly. A local execution log can show that code ran without proving that the research design was scientifically appropriate.

Evidence should therefore be matched to the claim.

Public quotation rule

Do not convert reconstructed wording into a quotation merely because a quotation would be more vivid.

Before publication, every quotation from an AI conversation should be checked against the original export, screenshot or equivalent authoritative record.

Internal verification and public auditability

The status frozen project evidence describes material preserved and checked within the research workflow; it does not mean that readers can independently reproduce the claim from the contents of this website. Some PISA outputs and historic records are held internally and are not republished because the resource separates public teaching examples from private project archives.

Worked cases now identify what is publicly inspectable and where interpretation relies on described but non-public material. A public case narrative is itself inspectable, but the existence of a narrative is not independent verification of an underlying statistic or contribution history. Any later provision of primary material would require separate evidential and rights review.
