Batch 4 C1: GA-R4 rule-6 ledger rotation -- 1187 -> 131 lines (GA-F13) ...

Bodies rotated VERBATIM to docs/archive/session-ledger-rotated-20260719.md
(Live state 2026-07-13, OPEN WORK VR1+VR0, NetBox write-path bugs, PINNED
rulings, standing lessons, state facts, project-completion, NetBox import
narrative). Routed-before-rotating (durable homes): juju format=line 3.6
trap -> appendix-A; guards-are-load-bearing -> operating-discipline; VR0
operational facts + admin/controller -> maas-as-built-reference.md
(lessons 1-6 verified already covered by platform-traps/L8). Live ledger
keeps header + machine-derived fence + two compact still-live blocks
(NetBox write-path bugs pointer, project-completion) + the bounded session
summaries. 131 < 300: the F1 cap is now ENFORCEABLE. Fences OK; ledger-
scan counters unchanged; repo-lint 0 fail.

Revert: git revert this commit (restores the 1187-line ledger).
