 ## Verification
-- Run Rust verification from `rust/`: `cargo fmt`, `cargo clippy --workspace --all-targets -- -D warnings`, `cargo test --workspace`
+- Run Rust verification from repo root: `scripts/fmt.sh --check`; for formatting use `scripts/fmt.sh`. Run Rust clippy/tests from `rust/`: `cargo clippy --workspace --all-targets -- -D warnings`, `cargo test --workspace`
 - `src/` and `tests/` are both present; update both surfaces together when behavior changes.

+------------------------------------------------
+- Selected next actionable backlog item because no active task was in progress.
+- ROADMAP #200: Interactive MCP/tool permission prompts are invisible blockers.
+- Files: rust/crates/runtime/src/worker_boot.rs, rust/crates/runtime/src/recovery_recipes.rs, ROADMAP.md, progress.txt.
+- Added tool_permission_required worker status and event classification for interactive MCP/tool permission gates.
+- Added structured ToolPermissionPrompt payload with server/tool identity and prompt preview.
+- Startup evidence now records tool_permission_prompt_detected and classifies timeout evidence as tool_permission_required.
+- Readiness snapshots now mark tool-permission-gated workers as blocked, not ready/idle.
+- Tests: targeted tool_permission regressions, full runtime test/clippy/fmt pending in Ralph verification loop.

 ## Verification
-- Run Rust verification from the repo root: `cargo fmt`, `cargo clippy --workspace --all-targets -- -D warnings`, `cargo test --workspace`
+- From the repository root, run Rust formatting with `scripts/fmt.sh` (or `scripts/fmt.sh --check` for CI-style checks). From this `rust/` directory, the equivalent command is `../scripts/fmt.sh`. Root-level `cargo fmt --manifest-path rust/Cargo.toml` is not the supported formatting command.
+- From this `rust/` directory, run Rust verification with `cargo clippy --workspace --all-targets -- -D warnings` and `cargo test --workspace`.
 
 ## Working agreement
 - Prefer small, reviewable changes and keep generated bootstrap files aligned with actual repo workflows.
