A historical photograph supports three different layers of knowledge—what is visibly observable, what its caption claims, and what the researcher infers—and those layers should be recorded separately.
Separating the layers makes uncertainty auditable and prevents an author's informal caption or a researcher's interpretation from being mistaken for direct visual evidence.
The complete LIT-35 review adds a high-value disputed-photograph case: visual observation, reproduced caption, descendant identification, earlier uncertainty, and inference must remain separate.

Atomic statement
A historical photograph supports three different layers of knowledge—what is visibly observable, what its caption claims, and what the researcher infers—and those layers should be recorded separately.
Evidence model
- Observation: visible material, spatial relation, condition, or marking.
- Caption claim: the photographer or author identifies a function, date, person, or historical meaning.
- Researcher inference: a broader interpretation derived from the image, caption, and other evidence.
Why this matters
Separation makes uncertainty auditable and prevents a caption or interpretation from being mistaken for direct visual evidence.
Evidence boundary
Peachee explicitly states at PDF sheet 271 that her captions are informal and not authoritative. The model therefore applies especially strongly to this source.
Development status
Developing. Operationally adopted for this corpus; broader methodological corroboration remains useful.
Peachee — September29 fresh audit qualification
All274 main-text/caption screens and all-page visual survey were reviewed, with22 enlarged details; embedded fine print keeps full-source completion open. Earlier descriptions of a complete review are superseded. Photo/caption locators now span paired screens. Image67 is an Ohio state price label, not automatic proof of federal bonded control; image112/caption113 concerns vertical alignment, not comprehensive structural safety. Caption206 states warehouse design intent, not measured sensory performance. Existing cross-source contributions and maturity are retained.
