Prefer Reversible One-Variable Experiments
When experimentation is appropriate, change one variable and preserve a path back.
#method-runtime#prefer#violin-stand-partner
Capture
- change bow speed but not pressure;
- alter one fingering;
- test one posture cue;
- compare one phrase under two conditions.
When experimentation is appropriate, change one variable and preserve a path back.
Why
Multiple simultaneous changes destroy evidence.
Why-Not
Not every instrument-facing action is reversible. Physical action requires stronger authorization.
Commit
Decision: When experimentation is appropriate, change one variable and preserve a path back.
Not every instrument-facing action is reversible. Physical action requires stronger authorization.
Confidence: Medium-high for public architecture; implementation details remain private and subject to launch evidence.
