Making outline
- Machine and lap close-clearance metal piston/cylinder with integral hydraulic port, gravity loading pieces and mechanically retained travel stops; realize pressure from independently transferred mass, gravity and effective area, checking leakage with a separate hydraulic-column artifact.
- Detailed procedure and acceptance remain unresearched.
What remains unresolved
- Manufacture, quantities, suitability and complete inventory remain unreviewed.
- Current memory-first method needs source and compatibility review.
Canonical reuse assessment
"Earlier independent pressure realization distinct from a gauge under calibration; full piston/seal/materials inventory remains open."
