Conditional κ = 0.001620246754858718: improved owner map for the PR604 cold-ended witness

[jeremykothe2]

Summary

Conditional κ = 0.001620246754858718. This is +9.97e-8 over PR604 (0.001620147045734211). The conservative model gives 0.001620246751982763.

This PR is DreamingOfClouds' PR604 (complex-571-cold14: 14 cold factory-scratch helpers per call ending at 4-dimensional frames, on our PR601 witness) with an improved literal owner map only. Dispatch is unchanged: ck ×44, atm3 ×22, jp8 ×6. A depth-2 ejection-chain polish of PR604's map changes the idle remainders, which the concave moment cost rewards. Against PR604's package, only data/OWNERS.json.gz, data/PLAN.json (windows and profile) and data/SPEC.json (expected values) differ. All construction code, cold_end and every other step, controls, proofs and the verifier are PR604's, byte for byte. The package directory is renamed complex-571-cold14-j1 so it doesn't collide with PR604's, and README, NOTICE and verify.sh name it accordingly.

All of PR604's soundness argument applies unchanged: Lean via #593/#599 (hpe_word_multi, exact_cold), exact (N) checks for every (0, U_b) pair, the guarded refactored cleanup, and wrapper-order enforcement. An owner map only changes which helper sits in which owner slot. PR604's strict physical owner audit, invoice and assembly re-check that from scratch.

Verification

research/complex-571-cold14-j1/verify.sh /tmp/complex-571-cold14-j1 ..   # SOURCE_ROOT holds worktrees pr568 pr569 pr571 pr575 pr583 at the pinned commits

Local result (Windows, CPython 3.11.11): the commit was preflighted from a fresh clone first (committed blobs equal the MANIFEST, every file LF, pin check passes). The official run from that clean clone of ddd81bc then gave PASS_COLD14_NATIVE_COMPLEX_AND_CITED_BIT, κ 0.001620246754858718, 55/55 stages exit 0, 478 s, with no reused baseline or locals. The receipt records MANIFEST sha256 d3196098…, equal to the committed MANIFEST.

GitHub CI has not run, and I make no claim about it.

Declarative inputs

Unlike our PR591–PR603, this package doesn't yet ship data/WITNESS.json, data/EXPECTED.json or data/cand.json, because our witness tools don't yet support PR604's cold_end step. Those files will follow as a separate commit on this PR, after their own official verify.

• jeremykothe2: PR601, PR600, PR596, PR593, PR592 and PR591 (the hyperplane-end base), and this owner map.

AI disclosure and authorship: Claude Opus 5.5 (Anthropic), running in the omp coding harness, found this owner map and prepared the PR. Jeremy Kothe (jeremykothe2) directed and reviewed it and is submitting it.

Scope

The result is conditional on the inherited all-size compiler, common-label/mutable-source realization, whole-call hosting, precision/tape/exact recovery, analytic transfer and the bit H1–H5 assumptions. It inherits PR604's draft status: PR604's own heavy verification was still running when this was opened. It is finite exact evidence, not an unconditional theorem, a complete Lean proof, or a practical speedup.
