Consolidates the branch: what changed (9 commits, 89 files), the evidence that
holds up (packaged -qaselftest, coordinate probes, budgets, 67 tests), all 15
defects found this cycle with severity/root cause/how each was caught, the
iteration toolchain and its current measurements, known limitations, and an
explicit list of what is NOT verified and needs a human.
Also records two things the earlier QA doc did not: the QA self-test is time-based
and can flake (one run reported walk 246 cm and pause FAIL; an immediate re-run
reported 761 cm and PASS with identical content), and the visual-loop scores are a
trend across iterations rather than an absolute quality number, because a wide
block view compared with a tight facade crop always scores low on edge similarity.
