SESSION CLOSE per GA-R4: bounded 14-line summary + full body to docs/archive/ (first live compliance run) ...

Grounding-audit session closed: Phases 1-4 complete and externally
reviewed, sweep plan drafted (687dfa8), Phase 5 deferred to a fresh
session. Fences OK post-append. F1 cap noted as not yet enforceable
pending the Batch-4 one-time rotation (GA-R4 rule 6). Revert: git revert
of this commit restores the pre-close ledger.
