3. Review Item Verification

Item 1: Codex R1~R3 Resolution & Server Routing

• Codex R1 (Server Routing on Attach & Verification):
  • Addressed across multi-agent-mux-resume/SKILL.md:
    • Case 3 (line 80): updated to herdr --session <server> agent attach <name>.
    • Workflow explanation (line 89): clearly notes that native herdr does not route on ambient environment variables, requiring explicit --session <server> for manual attach.
    • When NOT to use (line 130): herdr --session <server> agent attach <name>.
    • Verification block (lines 108–121): reads SERVER from the row's herdr_session (falling back to 'default' via .get('herdr_session') or 'default') and invokes herdr --session "$SERVER" agent get/read.
  • Confirmed via herdr --help that native herdr defines global syntax herdr --session <name> [options].
• Codex R2 (--dry-run Semantics):
  • In both multi-agent-mux-create/SKILL.md:58 and multi-agent-mux-resume/SKILL.md:98, table entries now accurately document that --dry-run skips spawn and registry updates, but runs pre-spawn checks and strips macOS com.apple.quarantine attributes.
• Codex R3 (Deleted Body Anti-Reintroduction Guard):
  • Implemented test_no_deleted_body_came_back() scanning all current blocks in all 8 SKILL.md files against DATA["removed"] and DATA["superseded"].
  • Independent of DATA["blocks"]: re-registering a deleted block under class c or b will still be detected and fail the test.
  • Self-verification in test_a_returned_body_is_caught_reindented_and_with_the_inventory_updated() ensures both exact base_sha and re-indented base_fingerprint matches trigger failures.

Item 2: Robustness of Fingerprinting

• Fingerprint definition: hashlib.sha256(" ".join(body.split()).encode()).hexdigest()[:12].
• Normalizes all internal whitespace and indentation, robustly detecting re-indented copies (e.g. within list items) without falsely flagging unrelated example blocks.

Item 3: Inventory Classification Integrity

• Git diff of tests/data/skill_code_blocks.json shows only boundary shifts for the updated resume verification block (start: 103, end: 128, sha: 8a468dfa43bd). Its classification remains strictly class: "b", kind: "verification".
• Added base_fingerprint fields to removed blocks.
• Added superseded entry for the folded create/SKILL.md call block (base_start: 263, class: "c", kind: "invocation").
• No block's class or kind was changed.

Item 4: Scope & Documentation Refinements

• Claude O4: Accurately documented MAM_KILL_ON_READY_TIMEOUT=1 for create exit 42 and --purge-conversation exception for stop exit 0.
• Boundaries: Strictly limited to documentation and test guard verification. Zero product code changes. Zero version bumps.
