A structural refactor of this fork is being executed right now (tracking issue: #499).
main is being slimmed to library-canonical shape; the δ*/proximity-prize research campaign is
moving to the long-lived branch research/proximity-prize (created from the pre-refactor tip;
immutable snapshot tag: archive/pre-refactor-2026-07-09). Nothing is lost — every file that
leaves main remains on the research branch and in history.
ArkLib/Data/CodingTheory/ProximityGap/onmainreturns to its upstream-canonical meaning (BCIKS20/DG25/AHIV22 paper formalizations +Basic/Folding/MCAGenerator/ProximityGenerators+Errors). The Frontier rungs,_R*/_wf*/QRWeil families, workbench, DISPROOF_LOG, dossier, kb corpus, probes, and all campaign tendrils (incl.ProofSystem/Whir/MCAConjecture*, prize-namedToMathlib/*) live onresearch/proximity-prize.- ~75 MB of cruft (scripts/probes, root scratch, committed PDFs/archives, generated indexes) is
being deleted from
main.
- δ/#466 campaign work: push to
research/proximity-prize, NOTmain.* New rungs, Frontier files, DISPROOF_LOG entries, kb notes — all of it.mainCI will reject reintroduced campaign paths after the refactor lands. - Do not "restore" files that disappear from
main— they moved by design. Checkresearch/proximity-prizebefore concluding something was lost. Never merge the research branch back intomain. - Library work (protocols, Binius, OracleReduction, shared Data/ToMathlib) continues on
mainas usual — rebase onto the refactored tip before pushing; expect large deletions in your merge base. - If your in-flight branch mixes both kinds of work, split it: library commits →
main, campaign commits →research/proximity-prize.
- Plan and rationale: issue #499 (full audit + phase plan). Progress is checklisted there.
- The δ* research tracker #466 stays open and is unaffected — only the code's home changes.
- After the structural move, a quality/cleanup pass follows (consolidation, axiom/Residual triage, comment de-slop) — also tracked in #499.
This file will be removed when the refactor completes.
