## Changes
Related to #545 and the permission-system removal in #555.
- Upgrade the shipped skill to v24 and remove obsolete filesystem grants, per-call approval flags, Electron file-root configuration, and DMG approval flags. Calls follow the user-requested investigation directly. Keep setup plan confirmation, actual OS requirements, and process/archive lifecycle boundaries.
- Correct the passive browser guide: endpoint/scope come from requests; ordinary local URL queries are retained, while credentials remain redacted.
- Audit canonical tool effects: declare possible DMG process/temp-directory effects, mark fresh extraction non-idempotent, and mark comparisons of supplied captures/PNGs as closed-world. Align artifact-provider capability effects with temporary mount-directory writes.
- Retain non-read-only hints for calls that add Evidence to the session; document that annotations are hints and that clients control their confirmation UI. Do not mislabel session mutations as read-only to suppress prompts.
- Regenerate package, skill, MCP, and product metadata from source.
## Verification
- `npm run test:focused -- <11 affected test files>`: **40 tests passed**, including skill transaction/backup/idempotence, SDK tools/list annotations, actual local capture/PNG comparisons, artifact extraction/containment/cancellation, DMG launcher/cleanup seam, setup confirmation, browser MCP and scenario MCP, CLI catalog parity.
- `npm run check`: typecheck, lint, format, knip, package metadata.
- `npm run docs:check`: generated catalogs, skill metadata, documentation facts, completion ledger, error schema.
No local real Hopper/Ghidra run: their adapters and analysis operations are unchanged. Native macOS DMG behavior is covered locally through the launcher seam; no local macOS/hdiutil claim is made.
Real browser verification passed using existing Headless Chrome143.0.7499.4: actual CLI/stdio MCP,9,331,407-byte PNG, passive capture/source maps, and owned/external scenario cleanup. An initial full Chrome143 run failed the existing screenshot-height assertion (1397 versus1536); the dedicated headless-shell run passed the complete verifier without code changes. The verifier run-lineage field remained unavailable; no lineage-coverage claim is made. Browser download into `.codex` was blocked by CDN403, so the successful run used an existing browser without changing host configuration.
