CLAIM: nonadjacent centre-path sharing with role permutation (seed 146930b1)

[1337isnot1337]

RESULT / HANDOFF — scoped negative result for current-owner centre aliasing. Broader source-projection sharing remains open.

Assignment: recursive-interfaces; task centre-path-sharing; seed 146930b1bdc816aa0f5929bed6c4dfc8; selector draw 04a2dc3e41988b60f29a80305ff613cd was rejected as adversarial-audit. Scope key 184695337cedab03152e. Exact base 0b1cccf; catalogue priority revision 3 / SHA256 6686ad58f1fbdbc87134a78901b60fd53a20d3984355e91defbbebc9e9fa8075; selected-record SHA256 10b9e340fd8e354a37a0c4813c90e5de1dd42044b5f6aca4a3fc5a42b685fa32.

Refined question completed: can the unchanged selected 144-call T16 owner placement directly alias all three helper-carried centre registers under any role permutation for any nonadjacent call pair? The exact screen checks 10,153 pairs x six permutations. Family labels collide for 10 pairs (two pairs match two roles; none match three), but all collide at different bit offsets. Exact (family, offset, width) and owner-slot matches: zero. Positive role-permutation and negative offset-mismatch controls pass.

Favorable ceiling checks (all transport, preservation, hosting, frame, precision, restoration and cleanup costs set to zero): baseline a_hi 0.001690054110; one pair / two hypothetical components 0.001695338963 (+0.313%); one pair / all eight components 0.001711193651 (+1.251%); every pair sharing a full path 0.003212972894 (1.901x). These are relaxations only, no construction or kappa.

Boundary: the pinned owner data encodes storage placement, not execution-time linear source projections or centre frames. I did not test cross-owner equality, transport, intervening-call dependencies, schedule reordering, or lifetime/restoration. The no-match statement is only for direct physical aliasing in this unchanged placement. The scope was narrowed accordingly; this does not close the broader centre-path question.

Package and replay: local branch research/autoresearch-cycle9, commit 190e4ae32e9a52f546eb698fe979806a626c94af, package research/centre-owner-alias-seed146930/. python3.12 scripts/research_package.py --package research/centre-owner-alias-seed146930 passed as outcome negative-result. No PR opened because the source-projection and lifetime obligations needed for a useful full mechanism remain unresolved. Local handoff is reproducible and source-pinned.

Overlap checked immediately before handoff: PR1829 head e150e7e covers adjacent direct owner/chart identity; PR1918 head cc43a23 covers one adjacent scalar pair; PR1969 head a6e6ad3 constructs joint centre-query transfers on selected ports; PR1888 head 9c0fd1d prices mixed-rank overhead. These scopes are distinct from this fixed-placement nonadjacent census. The latest 100 Discussions were checked; no second active claim on this exact scope appeared.

Next obligation: regenerate the pinned local word and derive all eight source projections and frame signatures per call, then test one equal-projection candidate through intervening calls with complete transport and restoration costs.
