+# Phase 4AP: exact, process-isolated conditioning interface
+
+This independent engineering branch repairs process ownership, not neural
+mathematics. Phase 4AO remains sealed `FAIL-POSTPROCESS-MODULE-IDENTITY`.
+It is not resumed or reclassified. No source in its 51-file inventory changes.
+
+## Registered scope
+
+The new registration covers 12 trial slots: **one explicitly imported, complete
+AO neural checkpoint and 11 new neural executions**, 14,400 covered ticks and
+13,200 new ticks. The imported slot is D1/reference/epoch-000. Its original case,
+requests, spec and checkpoint paths remain unchanged. Incomplete AO process
+evidence is never replaced by a successful AP process claim.
+
+Reuse both sealed AO request arrays byte-for-byte. Zero new sampler calls;
+no seed selection, resampling, rate/parameter rescue or data-selected retry.
+The two A epochs, original full 63-bit seeds, fixed PAM15 compartment, timing,
+D1/D0/frozen arms and reference/light recording modes are inherited exactly.
+New case specs differ only in output budget root/cap, with per-field derivations.
+Each epoch starts a fresh neural state. Only its own arm/mode's preceding delta
+is carried. This does not implement retention-state transition.
+
+## Process ownership
+
+Each new brain trial runs in a new `python -B` exec process using the frozen
+ordinary runtime. It seals its checkpoint before returning. The separate CPU
+update process loads only the frozen epoch adapter E and its verified dependencies,
+with CUDA hidden before scientific imports. The coordinator never calls E.
+No module binding is deleted, no private cache is cleared, no verifier is relaxed.
+
+The imported trial also receives fresh CPU postprocessing into AP, with no brain
+rerun. Its delta raw float32 bits and update receipt must match the separately
+sealed AO isolation diagnostic. NPZ container byte equality is not required.
+
+## Integrity and admission
+
+Commit all five new source files before preregistration. Bind actual input/source
+and prepared-case SHA-256, prior seals, source commit, actual saved requests,
+and the imported authority. Pin external registration SHA before executing.
+Job SHA is externally passed to each child. Verify input/source bytes before
+and after execution. Bind the complete output hash inventory, checkpoint/chain,
+authority, parent delta, actual child exit status and logs. Exclusive attempt,
+output and receipt paths prevent retry after partial failure.
+
+Single physical RTX 4090 UUID GPU-79f3a85d-adce-7833-7003-6488140ca596 only.
+Check all three existing ComfyUI queues before every brain trial; never stop or
+evict their services. Preserve precision configuration. Finite AP output cap
+4 GiB, reserve 10 GiB, child timeout 1,800 seconds. Stop on first failure and
+preserve all partial evidence. Never restart because the observing SSH command
+or tool times out; inspect actual process/log state first.
+
+## Pass gate and interpretation
+
+- Six reference/light pairs: exact observed spikes, counters, final state,
+  delay state and delta; inherited Q gate with independent expected effective
+  weight hash computed from frozen base, frozen fast-APL mask and actual delta.
+- Six zero-weight cross-arm comparisons: D0/frozen in each epoch and
+  D1/D0 before any update, separately for each recording mode.
+- Original U receipt recomputation, correct compartment/mask/floor, exact
+  D0/frozen positive-zero delta and actual D1 nonzero update coverage.
+- Second D1 epoch actually installs its own preceding delta file/raw bits.
+- All previous sealed AO/diagnostic/AN/AM and 28 protected roots remain intact.
+
+If all checks hold, status is
+`PASS-EXACT-PROCESS-ISOLATED-DELTA-INTERFACE-NOT-LEARNING`.
+If D1 has no actual nonzero update coverage, report
+`INCOMPLETE-NO-NONZERO-UPDATE-COVERAGE`, not a synthetic success.
+Failures remain failures; do not rerun with alternative inputs.
+
+Scheduled D is an artificial unconditioned-signal scalar, not a measured dopamine
+concentration and not multiplied by accepted DAN events. Report requested,
+accepted/rejected US events and actual DAN spikes separately. Unknown anatomical
+mapping stays unknown. The frozen APL approximation and its non-KC limitations
+remain disclosed. No intermediate light-mode state is claimed observed.
+
+This finite gate is **not learning success**, an A/B behavior evaluation,
+retention, full acquisition or a learned-model candidate. Full conditioning
+still needs its bounded registered gate/resource plan and validated post-update
+same-state transition. Phase 4C's five trial evidence is preserved via AM seals;
+this gate does not claim it reruns those trials. No game, RL, decoder, visual or
+Web work is included.
