Purpose

Ensure the same concept uses one symbol and different concepts do not collide.

Inputs

• problem parse and relationships;
• active methods/Qx/qx_method_card.md;
• approved code plans when available;
• question dependency map;
• existing planning/symbol_table.md.

Read legacy candidate pools only when method cards are absent.

Workflow

1. Extract inputs, outputs, parameters, decisions, states, indices, sets, functions, and intermediate quantities.
2. Preserve user-established notation unless it conflicts or is ambiguous.
3. Resolve:
   • same meaning with different symbols;
   • different meanings with the same symbol;
   • unit/domain conflicts;
   • Qx output-to-input handoff conflicts.
4. Classify each symbol by role and scope.
5. Save or update planning/symbol_table.md.
6. If a canonical symbol changes, classify it CANONICAL and run scoped consistency for affected Qx.

Table Fields

• symbol;
• plain name;
• definition;
• type: input, output, parameter, estimated parameter, decision, state, intermediate, index, set, function;
• domain/range;
• unit;
• scope/Qx;
• source artifact;
• notes or conflict resolution.

Rules

• Define every symbol before first use.
• Record units and domains when applicable.
• Use one notation for cross-question handoffs.
• Do not invent variables to make a table look complete.
• Do not maintain a separate verbose conflict log; record material resolutions in the table notes.

Verification

• Active method-card and code-plan variables are covered.
• No unresolved symbol or unit collision remains.
• Shared quantities agree across Qx.
• Downstream artifacts can cite one canonical table.
