This phase targets learned QKV functions across different layers, independent of cost. The six full-attention layers (indices 3/7/11/15/19/23) form 15 unordered pairs. No within-layer Q/K/V substitution, training, continuous R fitting, GPU, or new model download.

Read fixed primary protocol and findings with evidence limits. The original main protocol had no passing candidate. A later fixed one-source audit showed near-self-token retrieval and small readout errors, but failed strict fresh mean-JS/row-JS-P95/row-TV-P95 criteria; it is not relabeled as a primary pass.

core.py: exact discrete head assignment, actual attention parts, common-space head decomposition, fixed recipient V/gate/O transplants and temporal-cache controls.
protocol.py, fresh_samples.json: predeclared layer/unit/gate scope and untouched fresh texts.
run.py, fresh.py: calibration, frozen selection, old validation and gated fresh/network steps.
conditional.py: separately registered post-screen metric audit on one fixed H23 candidate; no fallback selection or later threshold changes.
audit_case.py: recompute selected fresh probabilities, self mass, shared top5 mass and actual-H3 versus same-H23 difference; no full-network intervention after failure.
report.py, audit.py: saved-data scientific plots, raw-count/matching/probability audits, SHA256 and explicit small Git delivery with external large-cache metadata.

Use the authorized remote CPU environment with the retained source checkpoint/cache:

OPENBLAS_NUM_THREADS=1 OMP_NUM_THREADS=1 venv/bin/python -B -m unittest tests.test_crossqkv -v
OPENBLAS_NUM_THREADS=1 OMP_NUM_THREADS=1 timeout 7200 venv/bin/python -B -m crossqkv.run --source runs/cpu-qwen35-2b --root runs/NEW_QKV_DIRECTORY

The main run requires a fresh directory and never overwrites prior protocol evidence. The recorded execution used runs/cross-layer-qkv-v2 after fixing a controls-variable shadowing error in the first attempt; old logs and its profile cache are retained. The first attempt took about 10.3 seconds, then a 60-second reserve was deducted from the next 7140-second run limit. The main study finished in about 74.8 seconds. The fixed conditional audit used only remaining shared budget and took about 105.3 seconds. Final tests/plots/audits fit comfortably within the two-hour computation budget.

All weights and caches stay on the server until explicit user deletion. Git contains all figure tables and the selected small probability matrices; large caches have exact paths/sizes/hashes in external-caches.json. Old validation texts were used in earlier experiments; the four fresh texts were fixed before the new cross-layer measurements.
