virtual-fly canonical initial checkpoint
Lineage: Canonical v1 initial state
This is the initial checkpoint of the current virtual-fly canonical experiment. Initial does not mean a randomly initialized artificial neural network. It means the initial neural checkpoint used by canonical v1 after constructing the simulation state from the released MaleCNS connectome and the canonical runtime assumptions.
This checkpoint was produced by the recorded canonical v1 experiment at original Git commit 7fa464aad7269d34f46f1171080b51e095d1d811. Its privacy-redacted public scientific equivalent is f9c86c904d67ff974f3c43d37aab3619bc93fc1b; the rewrite changed only historical local-path usernames, not executable source or canonical conditions. This checkpoint is global weight version 0 at aggregate neural step 0.
Checkpoint semantics
The manifest declares checkpoint_semantics=global-weights-only-v1 and step_semantics=aggregate-slot-neural-step-count-v1. The on-disk layout contains the full set of checkpoint arrays for loader compatibility, but canonical population training persists only the global synaptic weights across episodes. Membrane, spike, refractory, activity-trace, modulation, eligibility, body, and peripheral state are reset between episodes. Do not interpret the directory as a continuously persistent whole-fly biological state.
Relationship to the trained checkpoint
The corresponding canonical trained checkpoint will be published as ../trained using the same actual publication date. The short canonical run changed exactly 2,163,179 stored edges. Its frozen initial and final evaluations had the same categorical outcome, so the pair demonstrates current-semantics weight change rather than established behavioral improvement.

The checkpoint is not self-contained without a compatible MaleCNS snapshot and the virtual-fly runtime. Raw MaleCNS is intentionally not mirrored here; obtain it from the official MaleCNS source or use the GitHub reproduction path.

The checkpoint directory is kept in the native virtual-fly checkpoint layout so that the source repository can consume it without repacking. Raw MaleCNS source data and body assets are intentionally not included.
Integrity
SHA256SUMS records the exact hashes of the original checkpoint files selected for publication. Verify the checkpoint before use.
