 ### Step 2 — Map file structure
 
-Before defining tasks, list every file the iteration will create or
-modify, and what each one is responsible for. This is where
-decomposition decisions are locked in.
+Dispatch `ailang-plan-recon` with the spec path and iteration scope.
+Read the returned file-map. Lift the relevant entries into the plan's
+"Files this plan creates or modifies" section; the Boss may add or
+amend entries that recon missed.

+Dispatch carrier:
+
+| Field | Content |
+|-------|---------|
+| `spec_path` | path to the parent spec |
+| `iteration_scope` | which sections of the spec this iteration covers |
+| `focus_hint` | optional — subsystem or symbol to prioritise |
+
+Recon does NOT decide decomposition. Two recon dispatches per planner
+run is unusual but legitimate (e.g. one for the main spec sections,
+one with a sharper `focus_hint` for a tricky subsystem). Three or
+more is a smell — re-read the spec; the iteration scope is probably
+too broad.

+The plan's "Files this plan creates or modifies" section keeps the
+same shape:

-- Create: `crates/ailang-codegen/src/<new>.rs` — <one-line
