AO — bounded two-epoch conditioning-interface validation

This independent branch does not replace the frozen reference, runtime or any Phase 1–AN result. It tests the installation interface for the existing frozen eligibility-v2 rule. It is not a new dynamics hypothesis or a learned model.

Fixed, pre-outcome selection

• Master seed: 20260930; no seed search or outcome-based retries.
• First canonical block: physiological / PAM15 / reinforce_A / rep01.
• First normal paired epoch requesting a US, and its immediate successor.
• Both selected epochs are odor A (4-ethylphenol), not an A/B discrimination test. Exact recorded L glomerular/PN mapping and PN column order are retained.
• Each epoch is 120 ms: 100 ms CS plus 20 ms tail, US at tick 900.
• D1, D0 and frozen arms receive identical saved CS and DAN requests. The scheduled artificial D scalar is not measured dopamine concentration and is not multiplied by actual DAN request acceptance. Delivery is reported apart.
• Two executors (reference and light), two fresh epochs per arm: 12 calls, 14,400 timesteps. This does not authorize the full conditioning inventory.

Immutable neural semantics and authority

Each epoch resets V, g, refractory counters, APL state and both delay queues; the zero-initialized eligibility trace is computed from actual sealed spikes. Only the float32-mV plastic delta carries between epochs. No update occurs inside an epoch. Original graph, base weights, transmitter signs, numerical precision, APL parameters, frozen v2 rule and complete 14,232-edge mask remain unchanged. Full graph is 166,700 neurons and 25,582,938 edges.

Registration pins source snapshots, actual graph/APL/coefficient files, frozen L static resources, H mappings, the complete generated semantic plan and the 12 selected call descriptors before CUDA sampling. Sampling receipts bind the two generated request arrays before any brain call. Every input file is shared byte-for-byte between arms and executors. The full 63-bit input seed is separate from the inherited conservative 31-bit neural reset-control value.

A fixed first-seed CUDA check executes only the four original L sampling AST statements, compares sparse requests, and compares full63-bit versus low32-bit uniform matrices. This is a sampler test, not a neural trial or seed search. Two production and three diagnostic matrices are drawn; each is 1200×PN count, at most 2,000,000 uniform values. No continuous-time Poisson claim is made.

Each neural output is immediately sealed. Outside that seal, the coordinator binds original inputs, checkpoint events, actual v2 recomputation and the new delta snapshot. parent_snapshot_sha256 means the previous overlay NPZ file, not its manifest or the neural checkpoint. Epoch 2 must install that exact snapshot; D0/frozen deltas must stay positive-zero bitwise.

Finite gates and reporting limits

Required: all 12 processes complete; six reference/light pairs have identical sparse events, counts, final V/g/ref and terminal queues/APL; deltas are exact; D0/frozen identity holds; epoch 2 actually installs epoch 1 delta. D1 must have nonzero actual update coverage or the result is INCOMPLETE, never rescued by another input. Nonzero delta is interface coverage, not evidence of memory.

The light executor does not record intermediate floating states; no all-tick bitwise claim is inferred. This validation has only one training replicate, two A epochs, no independent behavioral evaluation, and no acquisition/reversal/ retention success claim. The post-update retention boundary is still unsupported.

Resource and failure policy

Use only RTX4090 UUID GPU-79f3a85d-adce-7833-7003-6488140ca596; admit a child only when all three ComfyUI queues are empty. Never stop or evict services. Cap new output at 4 GiB plus 10 GiB free reserve and each child at 1800 seconds. Preserve partial output and stop on any failure; no automatic brain retry. End by rechecking AN and AM seals and the inherited 28-root integrity inventory. Five old frozen reference results are retained from sealed AM evidence, not claimed to have been rerun by this small interface gate.
