Replaces the stale 2026-09-20 docs, which predated per-gun real attribution,
the offline gun range and the DrussGT boss, and whose verdicts were built on
virtual hit rates that turned out to be ANTI-correlated with reality.
docs/gun_rack_analysis.md (751 lines) covers: the test infrastructure
described honestly (offline range with its flaky-acceptance caveat, the 20
fixtures and what each set is good for, the live boss, and the A/B methodology
of per-run server-side real hit rate with an explicit overlap test); the
virtual-vs-real metric lesson with Spearman -0.374 and the point-vs-path A/B;
per-gun real performance and the 16-rule ranking A/B; the offline per-fixture
gun matrix; KEEP/MARGINAL/BELOW verdicts; and the five root-cause bugs with
before/after numbers.
docs/gun_rack_summary.md (58 lines) is the verdict table plus top actions.
The '~230 point' score-noise band that has been steering methodology all night
was re-derived from the artifacts rather than asserted: the 13 shipped-config
run scores span 175-526, s.d. ~105, i.e. a ~210-point 2-s.d. band.
Caveats recorded verbatim rather than softened: the offline==online acceptance
is flaky (typically 11/12 on unmodified HEAD), fixtures are perfect-information
and therefore optimistic vs live play, per-gun real N is small so single-gun
ordering is indicative, the headline numbers come from ONE wave-surfer
adversary, and HeadOn must stay despite being lowest because it is the floor
fallback (disabling it: 5.08% / 175 dmg vs 6.95% / 251 dmg).
