v1.50.2: the v1.50.1 review (HP-1501-01, HP-1501-02)

- HP-1501-01: v1.50.1 bounded layout positions and left room rectangles,
  polygon vertices, view_box and opening coordinates on bare _finite — the
  same absurd-magnitude failure, one schema over. _GEOM (±4) covers them all
  now, opening angles get ±360. And because a store may already hold such a
  vertex from before the door existed, contentBounds applies its canvas
  envelope to room geometry exactly as it does to device positions: the
  point renders where it is, the frame ignores it, a space of nothing but
  absurd points falls back to the whole canvas.
- HP-1501-02: a repair matching zero positions answered ok/moved:0 and
  replaced the one-deep backup with an empty one — a typo right after
  repairing the wrong space destroyed the promised way back. Empty match is
  nothing_to_repair now: no write, no revision bump, backup intact.

Old test fixtures carried view_box [0,0,100,100] from the render-unit days;
they now use the normalised box the product actually stores.
