# Discipline Skeleton -- Historiography

**Library:** Public RAM. **Authored by:** Epistemic Output Layer (S4). **Consumed by:** S4 at Phase D overlay.

Use when the invoked Librarian discipline is `historiography`. Historiography traces the evolution, causation, and change of phenomena over time through systematic source criticism and temporal analysis. Attach the three-axis block per causation claim or per narrative-change claim.

## Native Skeleton (preserve)

1. **Historical Question and Periodization** -- what is being explained, over what period, with what temporal segments.
2. **Primary Source Inventory** -- archival holdings, contemporaneous documents, oral histories. Provenance per source.
3. **Secondary Source Inventory** -- prior historiography; named schools of interpretation.
4. **Source Criticism** -- per source: authorship, dating, authenticity, bias, survival selection.
5. **Narrative Reconstruction** -- chronological or thematic. Causation claims explicit.
6. **Counterfactual and Contingency Reasoning** -- where relevant; pressure-tests the causal account.
7. **Historiographical Positioning** -- how this account engages, extends, or contests prior interpretations.
8. **Implications and Continuities to the Present.**

## Overlay Hooks

- Each **causation claim** ("Event A caused Event B via mechanism M under conditions C") or **narrative-change claim** is a slot.
- Typical claim types: causal (structural history) or interpretive (meaning, significance). Distinct slots.
- Source criticism feeds UPSTREAM integrity inputs; it is not the three-axis confidence.
- Surprise Register and Search Ledger render as top-level sections after Implications.
- Methodology trace: historiography tag, archival holdings identified, school of interpretation engaged.

## Native elements that MUST survive overlay
- Periodization.
- Source criticism (primary + secondary).
- Counterfactual and Contingency Reasoning.
- Historiographical Positioning.

Historiographical transportability is tricky: the "decision context" may be the present reader drawing lessons. Transportability rationale should name what analogy or mechanism is being asked to transport forward in time, and what the contextual-delta risk is.
