+# Plate Like Reference
+
+## When to read this file
+
+Read this reference when the request matches these triggers:
+
+- `bracket`
+- `plate`
+- `支架`
+- `板`
+
+## Object boundary
+
+Use this reference to improve first-pass CAD modeling structure. It is not a validator, factory, or engineering certification. Do not model adjacent assemblies unless the user explicitly requests them.
+
+## Recognition
+
+This node represents `mechanical_part.plate_like` in the generated taxonomy. It was mined from 2 source models.
+
+## Core invariants
+
+- The main body is a flat prismatic plate.
+- Holes, slots, and pockets should be positioned from datum edges or centerlines.
+- Thickness and edge treatment should be named.
+
+## Common variants
+
+- Keep variants driven by the user prompt and source evidence.
+- Prefer adding a child variant skill when one branch becomes too specific.
+- Do not collapse all examples into one fixed template.
+
+## Required parameter roles
+
+- `datum_edges`
+- `flat_body`
+- `holes_or_slots`
+
+## Feature roles
+
+- `datum_edges`
+- `flat_body`
+- `holes_or_slots`
+
+## Operation / construction sequence
+
+1. Build the primary base solid first.
+2. Add major bosses or protrusions second.
+3. Apply subtractive cuts, holes, pockets, and slots after the base is valid.
+4. Create repeated features through patterns rather than independent ad hoc geometry.
+5. Apply fillets and chamfers last.
+
+## Common failures to prevent
+
+- Unnamed magic dimensions hidden inside geometry calls.
+- Decorative features with no functional role.
+- Fillets or chamfers applied before major cuts.
+- Claiming engineering performance or standard compliance from reference guidance alone.
+
+## Validation targets
+
+- The generated model contains the core invariants above.
+- Major feature roles are visible or represented by named parameters.
+- Repeated features have consistent count, spacing, and datum relationship.
+- The output is a valid solid or explicitly requested assembly.
+
+## Exclusions
+
+- `shaft`
+- `vessel`
+
+## Source evidence summary
+
+- Source sample count: 2
+- Sample ids: 000124, 001082
+- Operation evidence: HoleWzd: 4, Chamfer: 4, Cut: 4, Extrusion: 2, LPattern: 2
+- Taxonomy confidence: 0.74
