%% data_flow.mmd - section 8 data flow / context propagation (flowchart LR)
%%
%% Placeholders (substituted by render_architecture.load_mermaid):
%%   NODES placeholder: node declarations: `<id>[<label>]`, one per line.
%%   EDGES placeholder: labeled-where-possible edges:
%%                      `A -->|<var>: <type>| B`, bare `A --> B` when no
%%                      parameter threads between the lanes.
%%
%% placeholder names are written as bare tokens (no double-curly)
%% so load_mermaid's single-pass str.replace cannot corrupt this header.
%%
%% Source: GenAiPlannerAttrDefinition rows on the planner drive which slots
%% populate which actions. Renderer (render_architecture._render_data_flow)
%% builds nodes/edges from the tree's planner-slot metadata; no slots ->
%% degenerate diagram with just `User --> Planner --> Actions` skeleton.
