Two independent defects, both found by running the gate honestly instead of
bypassing it:
1. packages/mosaic/framework/tools/orchestrator/README.md fails the repo's own
prettier config (unaligned markdown table). It landed via MERGED PR #868
(b79336a8). A merged commit that fails `pnpm format:check` means the CI format
gate did not block it — the gate is INERT. This is the P-QUEUE-001 /
P-CONFORMANCE-001 failure class ("gate-6 was inert fleet-wide") reproduced on
main, and it is exactly what this remediation mission exists to eliminate.
2. .prettierignore did not exclude Python build/test artifacts, so any local venv
drops ~2400 third-party files into format:check and makes the gate unpassable
in a working checkout. Added **/venv, **/__pycache__, **/.mypy_cache,
**/.pytest_cache, **/htmlcov — the same category as the existing
node_modules/dist/.next entries. This narrows what the gate SCANS (generated
trees), never what it ENFORCES over source.
