Phase 5.5: investigate stray v2.0.1 branch and PR #1, don't delete/close (FABRIC-3.6.md)

refs/heads/v2.0.1's tip is the exact merge-base with master -- a strict
ancestor, fully subsumed, confirmed by its own commit message ("master
fast-forwarded to v2.0.1, verified"). Stale ref hygiene debt, safe to
delete, not deleted here -- needs Captain Bob's explicit go-ahead.

PR #1 turned out not to be a stray reference at all: it's a PR from this
same branch against master, already closed (not merged) 20 seconds after
it was opened on 2026-09-18, before any of this reshuffle's work existed.
Nothing to resolve beyond recording what it is.
