+  "goal": "# Fix: Sub-agent file writes not tracked in API backend\n\n## Context\n\nWhen the API backend's agent spawns sub-agents that call `edit_file`/`write_file`, those files are missing from `outcome.files_touched`. This causes downstream nodes (like `simplify_opus`) to receive an incomplete file list in their prompt preamble.\n\nRoot cause: `spawn_event_forwarder` in `backend.rs` only matches top-level `ToolCallStarted`/`ToolCallCompleted` events. Sub-agent tool calls arrive wrapped as `AgentEvent::SubAgentEvent { event: Box<inner> }` and hit the `_ => {}` catch-all.\n\n## Plan\n\n**Single file change:** `lib/crates/fabro-workflows/src/cli/backend.rs`\n\nIn `spawn_event_forwarder` (line 51), replace the flat match with a helper that recursively unwraps `SubAgentEvent` to extract the inner `ToolCallStarted`/`ToolCallCompleted`:\n\n```\nmatch &event.event {\n    AgentEvent::ToolCallStarted { .. } => { /* existing logic */ }\n    AgentEvent::ToolCallCompleted { .. } => { /* existing logic */ }\n+   AgentEvent::SubAgentEvent { event: inner, .. } => {\n+       // Recursively extract file-tracking events from sub-agents\n+       track_file_event(inner, &pending_tool_calls, &files_touched, &last_file_touched);\n+   }\n    _ => {}\n}\n```\n\nExtract the file-tracking logic into a `track_file_event(event, pending, touched, last)` function that:\n1. Matches `ToolCallStarted` for `write_file`/`edit_file` → records to `pending_tool_calls`\n2. Matches `ToolCallCompleted` (non-error) → moves from pending to `files_touched`\n3. Matches `SubAgentEvent` → recurses into the inner event (handles sub-sub-agents)\n4. Otherwise → no-op\n\nThe existing inline match in `spawn_event_forwarder` calls `track_file_event` for both top-level and sub-agent events.\n\n## Verification\n\n1. `cargo test -p fabro-workflows` — existing tests pass\n2. `cargo clippy --workspace -- -D warnings` — clean\n3. Add a unit test: emit a `SubAgentEvent` wrapping a `ToolCallStarted`/`ToolCallCompleted` for `edit_file`, verify it appears in `files_touched`\n",
