# tests/test_tool_packs.py
"""TOOL_PACKS: advertise only the vertical packs a client uses; core is always on.

v1.6 track E adds the `settings` pack: the 22 SECTION 20 environment tools.
Styles (SECTION 18) and page setup / templates (SECTION 19) are drafting
essentials and stay in `core`, so `TOOL_PACKS=core` hides the environment
surface and nothing else.

v1.6 tracks B+G add the `mech` pack: SECTION 21's six part-model tools and
SECTION 22's three standard-parts tools and SECTION 23's five annotation
symbols - 14 in all. SECTION 24 (the sheet: frames, title blocks, revisions,
the parts list, balloons, xrefs, images, DWG) stays in `core` - universal
drafting, not a vertical - and files under its own `sheet` group.

v1.6 track F adds the `arch` pack: SECTION 25's twelve architectural tools -
the wall network, openings, stairs, rooms and their reader, schedules, the
grid and symbols, the furniture and sanitary catalogue, the exterior chains
and the whole plan from one spec. Lean gains four of them.
