PET v0.1.0

PET v0.1.0

First official PET release.

Included layers

• PET-Base: stable canonical representation, validation, encoding, decoding, rendering, and CLI contracts.
• PET-Metrics: canonical structural metrics, extended/research metrics, scan/query/atlas workflows.
• PET-METICA: operational rewrite-geometric toolkit for bounded research-facing analysis.

PET-METICA operational core

• pet branch-neighbors
• pet rewrite pair
• pet rewrite explain
• pet rewrite friction
• pet rewrite scan
• pet rewrite matrix

Reports and documentation

• bounded PET-METICA rewrite report
• canonical PET-METICA demo report
• operational observables documentation
• number-level vs shape-level distinction
• claim hygiene separating stable, bounded, exploratory, and non-core material

Status

PET-METICA is operational and research-facing. Rewrite scans, hub observations, friction observations, and family behavior are bounded empirical results, not general theorems.
