TEST 1 — transient inflationary shock, fix ON:
  inflation held at ~0 across the shock; dividend flat (yr10 = 0.0202, same path as no-shock).
  bond/GDP peaks at 23% during the shock, unwinds to 0% after.
  -> downward independence RESTORED: the anchor is defended through an inflationary shock, dividend intact.

TEST 2 — persistent +3% inflationary drift, bond/GDP ratio by interest rate:
  r=1%  (r<g): yr40 b=   84% of GDP, converges, steady b*=155%
  r=3%  (r=g): yr40 b=  120% of GDP, linear
  r=5%  (r>g): yr40 b=  179% of GDP, EXPLODES
  -> the fix is sustainable for persistent drift ONLY if r<g (positive carry). r>=g -> unbounded sterilization.

TEST 3 — runway to a 100%-of-GDP sterilization ceiling (then must abandon anchor or cut dividend):
  drift 2%/yr, r=3%: never hits ceiling in 40y
  drift 4%/yr, r=3%: ceiling hit at year 26
  drift 6%/yr, r=3%: ceiling hit at year 17
  drift 2%/yr, r=5%: ceiling hit at year 36
  drift 4%/yr, r=5%: ceiling hit at year 21
  drift 6%/yr, r=5%: ceiling hit at year 15
  -> a transient shock is absorbed with the dividend safe; a PERSISTENT real inflationary imbalance
     buys only a finite runway. No monetary instrument neutralizes a real imbalance forever.
