Owner

Corrects an inaccuracy from #178: geodesic-dome-mcp is not stdlib-only — it imports numpy and PIL (Pillow) at module load (lines 12-13, unguarded).

Why this matters

The #178 preflight only ran command -v python3. That passes on a host that has python3 but lacks numpy/Pillow — and geodesic-dome-mcp then fails only when the MCP host first invokes it. That's the exact late-failure the preflight was meant to prevent, so the check was effectively false confidence.

Changes

setup-mother.sh — after the python3-exists check, add python3 -c "import numpy, PIL"; abort with a pkg install py311-numpy py311-pillow hint if either is missing. Now the preflight verifies the real dependency.
MOTHER-SETUP.md — correct the prereq: python3 + numpy + Pillow, install via pkg install python3 py311-numpy py311-pillow.

Scope note: this hardens mother-on-osa setup (G4), separate from the ISO build lane. sh -n clean.

Corrects an inaccuracy from #178: `geodesic-dome-mcp` is **not** stdlib-only — it imports `numpy` and `PIL` (Pillow) at module load (lines 12-13, unguarded). ### Why this matters The #178 preflight only ran `command -v python3`.

geodesic-dome-mcp imports numpy + PIL at module load (not stdlib-only, as
#178 incorrectly stated). A present python3 therefore proves nothing — the
preflight would pass on a host missing numpy/Pillow and the tool would fail
only when the MCP host first invokes it.

- setup-mother.sh: add a 'python3 -c "import numpy, PIL"' check after the
  python3-exists check, with a pkg install py311-numpy py311-pillow hint.
- MOTHER-SETUP.md: correct the prereq from 'stdlib only, no pip' to
  'python3 + numpy + Pillow'.
