Give a distinct four-query word with the same six-input endpoint as #6766: 20 literal events instead of 21, or 22 instead of 23 after identical final normalizers. A four-input variant uses 18 events. Full q^4 coefficients and characteristic-two transfer agree. Event counts imply no weighted physical-cost saving.

Independently confirm the existing COMPLEX ceiling 0.0033072446849 with directed integer square roots and a separate rational atanh/Taylor checker. #6766 receives priority for the shared endpoint and broader COMPLEX+BIT result.

Base: 7c49fe3.
#6726: 435bbe9.

Reproduce (Python 3.12, stdlib):

python3 -B scripts/research_package.py --package research/binary-equal-orientation-fragments

Expected: PASS_BINARY_EQUAL_ORIENTATION_FRAGMENT_PACKAGE, PASS_INDEPENDENT_ATANH_TREE_REVIEW, PASS_REGISTERED_RESEARCH_PACKAGE.

Executed: exact 4/6-input maps and inverses; all 20 event omissions; phase, alias, normalizer, source and missing-query controls; 44 finite totals and an analytic unbounded tail. The independent engine includes 2,352 orientation comparisons and 15,180 triples. Positive local-gain controls prevent overstating the obstruction. Normal/-O, metadata, committed bytes/modes, export and Git-free checks pass. No randomized construction search.

No new κ. Fixed native tariffs, root and independently paid idles only. Physical installation, changed idle-sharing interfaces, roots and native tariffs remain open. All five selected assumptions remain.
