Ocarina V5 Explorer Readiness Summary

This generated companion page summarizes the V5 explorer state for tonykoop/ocarina. The richer studio explorer remains explorer.html.

Status: V5 explorer/build-packet candidate, not build-ready. The governing model is Helmholtz vessel flute, but chamber volume, voicing, shrinkage, and tuning remain measurement-required before production CAD or validated fabrication claims.

Authority Ledgers

Family/spec

family-spec.csv

Tracks vessel-flute model, chamber, voicing, shrinkage, tuning, and authority state.

Visual authority

visual-output-register.csv

Separates candidate CAD/design-table authority from derived previews and concept images.

Validation loop

validation-loop.csv

Names the next physical checks needed before promotion.

Provenance

cad/mcp-session-log.md

Records that this lane added local ledgers and did not run MCP generation sessions.

Current Authority

Artifact	Authority	Caveat
`ocarina-design-table.xlsx`	Candidate fabrication/design-table authority	Workbook values remain inferred until measured.
`cad/ocarina_master.scad`	Candidate CAD authority	Master-shape starter only; fipple and voicing are not validated.
`drawings/*.svg`	Derived preview	Not a reviewed DXF or production drawing.
`images/*.png`	Concept only	No dimensional, hole-location, or toolpath authority.

Release Gates

Measure fired clay shrinkage and update the master scale factor.
Water-fill chamber volume after forming, bisque, and glaze fire.
Validate OCA-P0/OCA-P1 fipple response and all-closed pitch.
Record measured frequencies and cents errors before freezing the 12-hole layout.
Export/review DXF or production CAD only after empirical voicing validation.
