docs + audit sweep 2026-07-23: fill-model lesson, five-test day, archive pass

FINDINGS: 'The fill model is the next scorer' section (A2 chain grade
-$7.54/fill x1344 confirms the surge kill; oracle harness chain grade
vetoes the ledger-positive tiers; virtual-book +26% variance footnote;
the five tandem tests and the makers-on-the-wall through-line).
HANDOFF: snapshot -> 07-23 (7-wallet rev 5, dark flags, Friday agenda
incl #20/#21). READMEs: /test consolidation row, measurement-harness
research row, study statuses + new script inventory.
Archive: value/ (closed 07-19) + its test, ETHERSCAN_MIGRATION.md,
order_probe v1 -> archive/; replay_out/ gitignored; links repaired.
Tests: all 7 active scripts pass post-move.
