+
+The agent owns source/dependency inspection, security-review coordination,
+compilation/scanners, evidence collection, revision/hash tracking, cleanup,
+and permitted dispatch/monitoring/audit. Do not ask the user to perform these

 ## Strategy
 
 1. **Anchor intent and failure.** First [capture developer intent from the current session](debug-security-review.md#capture-session-intent-first). Clarification is optional when the user is available; otherwise record unknown intent, continue static diagnosis/clearly authorized work and block uncertain execution/upload/effects. Record revisions, versions, trigger/inputs. [Collect existing evidence](#collect-existing-evidence) from supplied accessible runs or cached logs; otherwise start from source/fixtures, never dispatch for evidence. Compare existing runs with `gh aw audit RUN_ID RUN_ID_2 --group` for recurrence. Label observed/local/fixture/inferred/unavailable evidence.
 
-2. **Preflight MCP startup.** Read declarations/imports, credential references, startup commands/destinations without resolving secrets. Follow the [agentic security-review instructions](debug-security-review.md) before executing changed code or starting servers, including local reproductions and dry-run tooling. Before `gh aw mcp list WORKFLOW`, `gh aw mcp list-tools WORKFLOW --server NAME` or `gh aw mcp inspect WORKFLOW --server NAME`, account for startup/connections. Require isolated scoped test bindings, reviewed startup effects and metadata-only calls; otherwise use cached schemas. Do not mutate ambient credentials.

 3. **Reproduce one boundary.** Choose compilation/prompt/MCP/agent/safe outputs. Run the real component with existing edge test doubles, minimal inputs, output assertions, disposable files and a timeout. Mock missing context/APIs/credentials. Never contact production or disable the firewall; leave OIDC, approvals, hosted tokens and runners unverified.

+## Agent Ownership
+
+The agent performs the review: capture intent, inspect source and reachable
+runtime dependencies, prepare the evidence packet, run independent judges,
+resolve findings and missing coverage, execute permitted compilation/scanners,
+and record the result. Do not hand these steps to the user as a checklist.
+An incomplete judge response is missing review evidence, not a confirmed
+vulnerability or a reason to ask the user to inspect code. Gather the missing
+evidence within the judge limits below; never turn UNKNOWN into PASS.
+
+The agent also prepares exact revisions, hashes, credential-source/destination
+metadata, permissions, protections and run bounds for any required human
+validation. Ask only for decisions or authorization the agent cannot supply,
+such as protected-environment approval or authentication repair. Human
+validation remains required for live execution; it is not a request for the
+user to perform the technical review. Never retrieve secret values or claim
+to have verified credential validity/expiry when metadata cannot establish it.
+
+## Compile-Only Validation
+
+The agent may run the installed, trusted `gh aw compile WORKFLOW --dry-run`
+to obtain emitted locks and compiler/scanner evidence before the final
+source/lock review. This permission covers compilation, not execution of
+workflow scripts, changed compiler code, build hooks, harnesses or MCP servers.
+Review those separately before running them. The judges remain read-only.
+
+Emission is required: do not combine `--dry-run` with `--no-emit`. Compilation
+may run in the current checkout; a disposable checkout is optional, not a
+prerequisite or work to delegate to the user. Snapshot the pre-command contents
+and existence of every file the compiler can modify, including pre-existing
+user edits and untracked files. Preserve the diagnostic locks and results in
+session artifacts, then restore only compiler-generated changes to that
+snapshot. Remove only known files created by this invocation; never reset the
+worktree or overwrite concurrent edits. If ownership is unclear, stop cleanup
+and report the conflict.
+
+Record hashes of both the diagnostic output and the restored files. Reverting
+diagnostic output does not erase findings, satisfy a failed gate, or transfer
+the diagnostic lock's review verdict to a different live lock.

+## Agent ownership
+

+review coordination when required, compilation/scanners, evidence collection,
+finding resolution and cleanup. Do not give the user a technical preflight
+checklist to execute. Report concrete blockers and request only authorization
+or decisions the agent cannot supply. For debugging and live-test gates, follow
