+# Generic Rotational Part Reference
+
+## When to read this file
+
+Read this reference when the request matches these triggers:
+
+- `rotational part`
+- `turned part`
+
+## 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.rotating_part.generic_rotational_part` in the generated taxonomy. It was mined from 2 source models.
+
+## Core invariants
+
+- Identify the dominant base body before adding secondary features.
+- Keep repeated holes, slots, bosses, and cuts parameterized.
+- Preserve datum relationships over decorative symmetry.
+
+## 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
+
+- `circular_edges`
+- `cylindrical_faces`
+- `main_axis`
+
+## Feature roles
+
+- `circular_edges`
+- `cylindrical_faces`
+- `main_axis`
+
+## 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
+
+- `box-like housing`
+
+## Source evidence summary

+
+## Recognition
+
+This node represents `mechanical_part.rotating_part.shaft_like` in the generated taxonomy. It was mined from 6 source models.
+
+## Core invariants
+
+- A single dominant rotation axis organizes the part.
+- Cylindrical sections should be coaxial and station-based.
+- Journals, shoulders, grooves, threads, or keyways should attach to plausible axial regions.
+
+## 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
+
+- `coaxial_sections`
+- `journals`
+- `main_axis`
+- `shoulders`
+
+## Feature roles
+
+- `coaxial_sections`
+- `journals`
+- `main_axis`
+- `shoulders`
+
+## Operation / construction sequence
+
+1. Define the shaft axis and axial stations first.
+2. Build the coaxial stack by revolve or fused cylinders.
+3. Cut bores, keyways, grooves, threads, or splines after the base shaft is valid.
+4. Overshoot subtractive tools through the shaft.
+5. Apply shoulder reliefs, chamfers, and fillets last.
+
