Adding this check surfaces misconfiguration early — e.g. a `storage_dir` override pointing to a nonexistent or read-only path.\n\n## Plan\n\n### 1. Add `check_storage_dir` pure function in `doctor.rs`\n\n**File:** `lib/crates/fabro-cli/src/commands/doctor.rs`\n\nAdd a function like the existing `check_config`:\n\n```rust\nfn check_storage_dir(path: &Path, readable: bool, writable: bool) -> CheckResult\n```\n\n- **Summary always shows the resolved path** (e.g. `/Users/you/.fabro`) — same pattern as `check_config` which puts the path in `summary`.\n- **Pass** — dir exists, readable, writable.\n- **Error** — dir doesn't exist, or not readable, or not writable. Remediation: create it or fix permissions.\n- Details (verbose): existence, read, write status as individual lines.\n\n### 2. Gather state in `run_doctor`\n\nBefore the pure-checks section, resolve the storage dir and probe it:\n\n```rust\nlet storage_dir = cli_settings.storage_dir();\nlet exists = storage_dir.is_dir();\nlet readable = std::fs::read_dir(&storage_dir).is_ok();\nlet writable = tempfile::tempfile_in(&storage_dir).is_ok();  // or write+remove a temp file\n```\n\nUse `std::fs` directly — no async/live probe needed for local filesystem checks.\n\n### 3. Add to \"Required\" section\n\nInsert `check_storage_dir` result into the \"Required\" section, after the \"Configuration\" check and before \"LLM providers\" — storage is fundamental.\n\n### 4. Add unit tests\n\nFollow the existing test pattern (pure function tests with synthetic inputs). Cover:\n- Dir exists + readable + writable → Pass\n- Dir doesn't exist → Error\n- Dir exists but not writable → Error\n\nUse a `tempdir` for real filesystem assertions in a couple of tests.\n\n### 5. Add integration tests in `it/cmd/doctor.rs`\n\n**File:** `lib/crates/fabro-cli/tests/it/cmd/doctor.rs` (existing, has 4 tests)\n\nAdd 2 tests using the existing `test_context!()` + `fabro_snapshot!` pattern:\n\n- **`storage_dir_shown_in_output`** — `TestContext` already creates a temp `storage_dir` and sets `FABRO_STORAGE_DIR`. Run `doctor --dry-run`, snapshot-assert that \"Storage directory\" line appears with the path in the summary.\n- **`storage_dir_missing_shows_error`** — Override `FABRO_STORAGE_DIR` to a nonexistent path via `.env(\"FABRO_STORAGE_DIR\", \"/tmp/nonexistent-fabro-xyz\")`. Run `doctor --dry-run`, snapshot-assert that the check shows error status with the path and remediation text.\n\nBoth tests use `--dry-run` to skip live probes and `fabro_snapshot!` for inline snapshot assertions. Add a filter to normalize the temp dir path (e.g. `[STORAGE_DIR]`).\n\n## Files to modify\n\n- `lib/crates/fabro-cli/src/commands/doctor.rs` — new check function + gather state + wire into section + unit tests\n- `lib/crates/fabro-cli/tests/it/cmd/doctor.rs` — 2 new integration tests\n\n## Verification\n\n- `cargo nextest run -p fabro-cli -- doctor` — unit + integration tests pass\n- `cargo clippy --workspace -- -D warnings` — no lint issues\n- `fabro doctor` — shows new \"Storage directory\" check with the resolved path\n- `fabro doctor -v` — shows detail lines for existence/read/write\n- `FABRO_STORAGE_DIR=/nonexistent fabro doctor` — shows error for missing dir\n\n",
