The Goal-1 host refactor is now functionally complete — all 6 stages, §2.5, and
all three Stage-5 seam-trait tightenings have landed (EncoderCaps = 0ccd0fe).
Remaining is non-blocking: the optional namespace collapse (decision: skip —
pure churn), the merge to main (confirm with the user — outward-facing), and the
pf-vdisplay slot-reclaim driver fix (reassigned to windows-host-rewrite.md, the
greenfield driver rewrite, alongside the fullscreen-game capture bug).
