Hama gold teaching — every-run retrieval of construction perfection.

operations:

• retrieve: data {intent: str, k: int=3} -> top-k gold exemplars (BARAL municipal + Hama A001/A020) via cosine similarity

• similarity: data {features: dict, gold_id: str="hama_A001"} -> 0-100 vs Hama

• extract: data {} -> extract current drawing features via ezdxf (layers, dims, hatches, viewports) for scoring

• score: data {features: dict} -> composite Hama 0.5validator +0.3vision+0.2*sim

Block ops: list/insert/define/get_attributes/update_attribute.

Decor — hatches, fills, symbols, furnishing blocks (YQArch bg/xf).

Dimensions — linear/aligned/angular/radius/leader with NBC ArchTick 45° DIMTAD 1.

Drawing management: create/open/save/info/purge/plot_pdf/get_variables/setup_nbc_standards.

Generic entity ops: create_line/circle/polyline/rectangle/arc/ellipse/mtext/hatch/list/count/get/erase/copy/move/rotate/scale/mirror/offset/array/fillet/chamfer.

Generate any Hama-level drawing: plan 1:100, section 1:20, detail 1:5, schedule, site 1:200.

operation: drawing_type e.g., plan, section, detail, schedule, site, elevation, wall_detail data: {scale: "1:100"/"1:5"/"1:20", building: [WxH], grid_x, grid_y, walls, title, detail_type, kind, building, etc}

Layer ops: list/create/set_current/set_properties/freeze/thaw/lock/unlock.

Opening — doors/windows (YQArch ad/aw) with NBC door width gate.

Section — cut lines, section views (generates 1:50/1:20 sections).

Stair (YQArch ltj / fallback geometry) — tread/riser validated via 2R+T [600,650].

System — status/undo/redo/purge/plot_pdf/execute_lisp/get_variables (ALLOW_RCE gate).

View — zoom_extents/zoom_window + screenshot (canvas-only if available).

Wall operations (YQArch ww) — create/list with NBC thickness gate.
