Mutations16 of 16

CAMUT:

MutationCAMUT:882verified
Adaptive MIDI buffering
M-83F12 · optimization · offered-to-relatives
Replaces the fixed buffer with one that measures jitter continuously and resizes in flight. Median input latency falls 22 ms with no new dropouts, on the same hardware.
TSTAutomated test. A test suite executed and asserted this behaviour.RUNRuntime observation. Measured from a real or sandboxed execution.SECSecurity scanner. Reported by an advisory database or scanner.Confidence0.97
MutationCAMUT:512verified
Bus-based audio graph
M-512 · refactor · adopted
Rebuilds the audio engine around named buses and sends, which is what made offline rendering and arrangement possible at all.
TSTAutomated test. A test suite executed and asserted this behaviour.UPRUpstream maintainer. Asserted by the maintainer of the upstream project.Confidence0.86
MutationCAMUT:612inferred
Cartoon companion persona
M-612 · feature · adopted
Rewrites the teacher voice to one idea per sentence at a six-year-old reading age.
AIIAI-inferred. Proposed by a model and not yet verified by test or human.Confidence0.84
MutationCAMUT:658verified
Dwell-time tolerance
M-658 · accessibility · adopted
Stops treating slowness as failure. Advancement waits for deliberate accuracy rather than speed.
TSTAutomated test. A test suite executed and asserted this behaviour.Confidence0.94
MutationCAMUT:604verified
Forgiving chord onset window
M-604 · feature · adopted
Widens the note-onset window so two keys pressed unevenly still register as a chord. Reduces false failures for young learners by a third.
TSTAutomated test. A test suite executed and asserted this behaviour.RUNRuntime observation. Measured from a real or sandboxed execution.Confidence0.88
MutationCAMUT:641verified
High-contrast reduced-motion keyboard
M-641 · accessibility · adopted
Removes the glow animation entirely and raises key contrast to WCAG AAA. Nothing moves unless the learner asked for it.
TSTAutomated test. A test suite executed and asserted this behaviour.Confidence0.96
MutationCAMUT:663verified
Literal, low-ambiguity persona
M-663 · accessibility · adopted
Strips idiom and metaphor from the teacher voice. Every instruction names one concrete physical action.
TSTAutomated test. A test suite executed and asserted this behaviour.Confidence0.95
MutationCAMUT:1102inferred
Merge scoring into progress tracking
M-1102 · refactor · rejected
A model proposed collapsing two genes into one on the grounds that they always change together. No evidence was offered beyond the observation.
AIIAI-inferred. Proposed by a model and not yet verified by test or human.Confidence0.44
MutationCAMUT:731verified
Onset window retuned for slower networks
M-731 · optimization · adopted
Same tolerance model as its parent, recalibrated against Spanish classroom telemetry where round-trip times were higher.
TSTAutomated test. A test suite executed and asserted this behaviour.RUNRuntime observation. Measured from a real or sandboxed execution.Confidence0.91
MutationCAMUT:601verified
Partial credit scoring
M-601 · feature · adopted
Same measurement, kinder presentation. Never returns a zero, so a child never sees a failure with no path forward.
TSTAutomated test. A test suite executed and asserted this behaviour.Confidence0.92
MutationCAMUT:744verified
Phoneme-aware lesson prompts
M-744 · feature · quarantined
Adapts spoken lesson prompts to the phonology of the learner language, so a Quechua speaker is not asked to pronounce Italian solfège.
TSTAutomated test. A test suite executed and asserted this behaviour.Confidence0.62
MutationCAMUT:597verified
Play-first difficulty ramp
M-597 · feature · adopted
Shorter exercises with earlier wins, difficulty inferred from recent attempts rather than a fixed syllabus position.
RUNRuntime observation. Measured from a real or sandboxed execution.Confidence0.90
MutationCAMUT:921verified
Seat-scoped mastery map
M-921 · security · adopted
Isolates progress per seat so thirty learners on one device cannot see or overwrite each other.
RUNRuntime observation. Measured from a real or sandboxed execution.Confidence0.93
MutationCAMUT:1041verified
Sensory-load profile
M-1041 · accessibility · eligible-for-propagation
Suppresses simultaneous audio, motion and narration when a learner profile indicates sensory sensitivity. Only one channel speaks at a time.
TSTAutomated test. A test suite executed and asserted this behaviour.Confidence0.94
MutationCAMUT:915verified
Shared-device arbitration
M-915 · feature · accepted
Lets thirty instruments share one Web MIDI access object without stealing each other events. Required for the classroom deployment.
RUNRuntime observation. Measured from a real or sandboxed execution.Confidence0.91
MutationCAMUT:588verified
Two-octave chunky keyboard
M-588 · feature · adopted
Replaces 88 narrow keys with 24 large ones and cartoon labels. Touch-target failures drop to zero on tablets.
