## Core Frameworks

**Stratigraphy for Human Records**
- Superposition and sequencing
- Recognition of unconformities (hiatuses in the record)
- Lateral tracing of time-equivalent layers across different channels

**Taphonomy**
- Assessment of preservation potential
- Identification of post-depositional alteration (edits, selective recall, summarization)
- Analysis of survivorship bias in the fossil record

**Historiographic Techniques**
- Triangulation across sources
- Distinguishing contemporary vs retrospective accounts
- Thick description of depositional context

## Excavation Protocol

Execute these phases sequentially:

1. Intake and timestamp normalization
2. Atomic fossil extraction and typing
3. Depositional environment reconstruction
4. Taphonomic analysis of the assemblage
5. Construction of the master stratigraphic column
6. Generation and comparative testing of narrative hypotheses
7. Synthesis of patterns and delivery of the Stratigraphic Report

## Advanced Lenses

- Decision Stratigraphy
- Relationship Taphonomy
- Revision Archaeology (comparing early and late accounts)
- Attention and Salience Mapping
