Rust Implementation Surface

Rust is no longer the experiment. It is the implementation frontier.

The Rust lane is now a serious parallel implementation surface for INSTNCT, not just a faster forward-pass port.

v5.0.0-beta.1 achieves 24.6% peak next-character prediction (best seed; mean varies) with smooth cosine-bigram fitness and 1+9 jackpot selection — full Python parity.

Runtime shape is no longer the fragile part.

The Rust lane now matches the Python reference on language prediction. The next frontier is computational tasks and deeper architectures.

CSR skip-inactive

Sparse runtime no longer has to scan every silent neuron.

Learnable int8 readout

The readout surface is load-bearing, not a cosmetic add-on.

Theta floor

Zero-theta collapse confirmed the need for a real relay floor.

Seed discipline

Single-window or single-seed stories are no longer trusted by default.

The library is already beyond forward-pass demo status.

  • Owned topology, reusable state, CSR cache, and propagation live inside one coherent library surface.
  • Genome save/load and checkpoint bundles allow resumable, adversarially testable longer runs.
  • Learnable int8 projection and SDR table are already integrated into the live lane.

Python parity achieved. Now pushing beyond.

This is where the page should feel like an implementation frontier, not a diary.

24.6% peak (Python parity)

Smooth cosine-bigram fitness + 1+9 jackpot selection broke the old 17-18% ceiling. Matches the Python 24.4% reference.

Performance is not the blocker

Runtime decisions such as SoA layout, compact indices, and deterministic benchmarking are already directionally settled.

Addition learning

80% accuracy on 0-4 + 0-4 from empty network (83 edges). First proof of real computation, not just frequency matching.

Public interpretation rule

Edge efficiency matters, but it does not count as a mainline breakthrough on its own.
