 Archive extraction can overwrite files outside the directory chosen for the import.
 
+#### Root Cause
+
+The extractor joins the entry name to the output directory without checking whether the destination stays inside it.
+
 #### Validation
 
 The extractor combines the output directory with the entry name and passes the resulting path to the writer. It never checks that the destination stays inside the output directory.
 
 Validation method: Static source review
 
+Evidence:
+- The untrusted entry name reaches the filesystem write without normalization or a containment check.
+
+Limitations:
+- The extraction route was not exercised dynamically.
+
 #### Dataflow
 
 The archive supplies an entry name. The extractor uses that name to select the file it writes.

 New drafts and imports use `codeEvidence`, `rootCause`, `attackPath.dataflow`, and `evidenceRefs`. Legacy aliases (`code_evidence`, `root_cause`, `dataFlow`, `data_flow`, and `evidence_refs`) are rejected on writes. Optional fields must match the current schema; invalid values are not silently repaired or removed. Historical sealed reports remain readable without changing their saved bytes.
 
+Before completing a new scan, each finding must include at least one genuine `codeEvidence` snippet, a `rootCause` explanation, `attackPath.dataflow`, and `validation.method`, a `validation.summary` or `validation.result`, and supporting `validation.evidence` or `validation.evidenceRefs`. Dataflow may be concise text, an object with `summary`, or an object identifying `source` and `sink`. Static source tracing is a valid method; state what was observed and any runtime or deployment uncertainty in `validation.limitations`. Read and verify the snippets against the reviewed source while it is available; a location label is not code. These are completion requirements, not a requirement to run an exploit or lengthen the prose. Incomplete checkpoints and stopped scans can retain partial evidence. Completion reports missing fields without discarding the draft so a continuation can repair them.

 - Use `attackPath.summary` to briefly explain how to reproduce the issue.
 - Explain how the code causes that product behavior in `rootCause.summary`. Use plain language and avoid repetition.

 1. Resolve the authorized target and scope. For a scoped directory use that directory as `targetPath` and `scope: "."`. For a continuation, call `get_codex_security_scan_context` with its `scanId` and supplied `handoffClaimToken`. Use its saved identity and scope. If its mode is Standard or diff, continue with the corresponding scan skill. Follow `../../references/scan-prologue.md` for source access and context updates.
 2. For a new target, call `inspect_codex_security_setup({ targetPath, scope: ".", mode: "deep", projectConfigPath? })`. Show the effective settings and their sources. `max_discovery_runs` caps the total number of Standard scans, including when several run together. Pass a project file only when the user selected it. Existing scans use their saved configuration.
 3. For a newly launched native scan with a supplied scan ID, inspect `otherRunningDeepScans` in the result of `get_codex_security_scan_context` once. Target-based setup previews have no scan ID. If another Deep scan is active, show its target, phase and human-friendly start time. Explain the additional CPU, memory and token use. Offer **Cancel (Recommended)** and **Continue** using `request_user_input`, then `request_codex_security_user_input` or plain chat if unavailable. Wait for an explicit choice. A dismissed dialog is not a cancellation. Cancel only the new scan if requested.
-4. Follow `../../references/access-advisory.md`, then call `start_codex_security_deep_scan({ scanId, handoffClaimToken? })` for an existing scan or `start_codex_security_deep_scan({ targetPath, scope: ".", userContext?, projectConfigPath? })` for a new target. Reuse the project file selected at setup. Await the tool. If the tool runner returns a running cell ID, wait on that cell until it returns the scan result. If the connection closes, rejoin with the same arguments. Report a terminal failure with its saved results. For a policy refusal, identify the worker from its saved error when available. On explicit cancellation call `cancel_codex_security_scan({ scanId })` from the owning thread.

 5. For an SDK-owned scan, return the host's scan ID and manifest path so the SDK can finalize it. When the tool returns `completion`, link its generated `report.md` and canonical artifacts. Use `completion.scan.usage` and any separate cost estimate to report usage per `../../references/final-report.md`. Distinguish a completed audit with zero findings from a deadline reached before any audit completed.
