night 2026-09-13/14: first "be a customer" rotation (adventurelog) — 7 defects found, 13 rows closed

New runbooks/nightly-rotation.md; observations_gate.py reads every section
(R-471); target-selection.md names real paths (R-461); R-93 carries the
fact that drill-r50 is gone. Register: R-473/R-474/R-466/R-471/R-453/R-461
and v0.240.0's R-477/R-478/R-480/R-482/R-484/R-485/R-486 closed; R-481,
R-483, R-487, R-488, R-489 opened. 09 §6.1, 07 §6, CONTEXT, STATUS note.
