These appear as REGISTER_SPILL findings\n because both are in AARCH64_CALLEE_SAVED.

Leaf\n functions must allocate stack space explicitly; no red-zone analysis needed.\n - Apple AArch64 (M1/M2) and Linux AArch64 both use AAPCS64 with no red zone;\n the analysis is platform-agnostic.\n\nCalled by check_rust_asm.py.

Verify `compile_db` file exists at the given path.\n2. Verify at least one entry in the compile DB resolves to an existing source file and working directory.\n3. Attempt a trial compilation of one representative TU using its captured flags to confirm the codebase is buildable.\n4. Verify `{baseDir}/tools/extract_compile_flags.py` exists and is executable.\n5. Verify `{baseDir}/tools/emit_ir.sh` exists and is executable.\n6. If `enable_asm=true`: verify `{baseDir}/tools/emit_asm.sh` exists; if missing, set `enable_asm=false` and emit a warning.\n7. If `mcp_mode != off`: run `{baseDir}/tools/mcp/check_mcp.sh` to probe MCP availability.\n - If `mcp_mode=require` and MCP is unreachable: **stop the run** and report the MCP failure.\n - If `mcp_mode=prefer` and MCP is unreachable: set `mcp_available=false`, continue, and apply confidence downgrades in the report assembly phase.\n\n**Step 3 — Common preflight** (always):\n\n8. Verify `{baseDir}/tools/generate_poc.py` exists and is executable. If missing: **stop the run** — PoC generation is mandatory.\n\n**Step 4 — Rust preflight** (skip if `language_mode=c`):\n\n9. Verify `cargo_manifest` file exists (must be a `Cargo.toml` path).\n10. Run `cargo check --manifest-path \u003ccargo_manifest>` to confirm the crate is buildable. If it fails: **stop the run**.\n11. Verify `cargo +nightly --version` succeeds. If not: **stop the run** — nightly toolchain is required for MIR and LLVM IR emission.\n - Note: use `~/.cargo/bin/cargo +nightly` (rustup proxy) rather than a system cargo that may not support the `+toolchain` syntax.\n12. Verify `uv --version` succeeds. If not: **stop the run** — `uv` is required to run Python analysis scripts.\n13. Verify `{baseDir}/tools/emit_rust_mir.sh` exists and is executable. If missing: **stop the run** — MIR analysis is required.\n14. Verify `{baseDir}/tools/emit_rust_ir.sh` exists and is executable. If missing: **stop the run** — LLVM IR analysis is required.\n15. For each tool below: if missing or not executable, warn and mark that capability as skipped (do not fail the run):\n - `{baseDir}/tools/emit_rust_asm.sh` — if missing, set `enable_asm=false` for Rust; warn `STACK_RETENTION`/`REGISTER_SPILL` findings will be skipped.\n - `{baseDir}/tools/diff_rust_mir.sh` — if missing, warn that MIR-level optimization comparison will be skipped.\n16. For each Python script below: if missing, warn and mark that sub-step as skipped (do not fail the run):\n - `{baseDir}/tools/scripts/semantic_audit.py`\n - `{baseDir}/tools/scripts/find_dangerous_apis.py`\n - `{baseDir}/tools/scripts/check_mir_patterns.py`\n - `{baseDir}/tools/scripts/check_llvm_patterns.py`\n - `{baseDir}/tools/scripts/check_rust_asm.py` — if missing, assembly analysis findings (`STACK_RETENTION`, `REGISTER_SPILL`) will be skipped even if `enable_asm=true`.\n\n**Step 5 — TU / crate enumeration**:\n\n- **C/C++** (skip if `language_mode=rust`): Parse `compile_db` and enumerate all translation units. Apply `max_tus` limit if set. Filter by `languages`. Compute `tu_hash = sha1(source_path)[:8]` for each TU. Run a lightweight grep across TU sources for sensitive name patterns (from merged config) to produce `sensitive_candidates`.\n- **Rust** (skip if `language_mode=c`): Compute `rust_tu_hash = sha1(abspath(cargo_manifest))[:8]`. Set `rust_crate_root = dirname(cargo_manifest)`.\n\n**Step 6 — Create work directory**:\n\n```bash\nRUN_ID=$(date +%Y%m%d%H%M%S)\nWORKDIR=\"/tmp/zeroize-audit-${RUN_ID}\"\nmkdir -p \"${WORKDIR}\"/{mcp-evidence,source-analysis,compiler-analysis,rust-compiler-analysis,report,poc,tests,agent-inputs}\n```\n\n**Step 7 — Write `{workdir}/preflight.json`**:\n\n```json\n{\n \"run_id\": \"\u003cRUN_ID>\",\n \"timestamp\": \"\u003cISO-8601>\",\n \"repo\": \"\u003cpath>\",\n \"language_mode\": \"\u003cc|rust|mixed>\",\n \"compile_db\": \"\u003ccompile_db or null>\",\n \"cargo_manifest\": \"\u003ccargo_manifest or null>\",\n \"rust_crate_root\": \"\u003cdirname(cargo_manifest) or null>\",\n \"rust_tu_hash\": \"\u003chash or null>\",\n \"opt_levels\": [\"O0\", \"O1\", \"O2\"],\n \"mcp_mode\": \"\u003cmcp_mode>\",\n \"mcp_available\": true,\n \"enable_asm\": true,\n \"enable_semantic_ir\": false,\n \"enable_cfg\": false,\n \"enable_runtime_tests\": false,\n \"tu_count\": 0,\n \"tu_list\": [{\"file\": \"/path/to/file.c\", \"tu_hash\": \"a1b2c3d4\"}],\n \"sensitive_candidates\": [],\n \"tools_verified\": [\"uv\", \"cargo+nightly\"],\n \"notes\": \"\"\n}\n```\n\n**Step 8 — Write `{workdir}/orchestrator-state.json`** with the full state structure.\n\nReport each preflight failure with the specific check that failed and the remediation step.\n\n**After completion**: The agent's response includes the `workdir` path. Read `{workdir}/orchestrator-state.json` to initialize:\n\n- `workdir` — use for all subsequent phases\n- `routing.mcp_available` — MCP probe result\n- `routing.tu_count` — number of TUs to process\n- `key_file_paths.config` — path to merged config file\n\n## State Update\n\nThe `0-preflight` agent writes the initial `orchestrator-state.json`.
