docs(herdr): Keep Codex recovery prose at the external contract

Problem

The policy review of #473 at 84ce7ffc3d5093aec469526c63f654526beeda6c identified presentation-only duplication in skills/herdr-teamlead/references/dispatch-recovery.md:624–626: prose repeats internal prompt/proof transitions owned by source_prompt. See review 5255112435 and rules/script-as-black-box.md.

Proposed approach

Shorten this added Codex paragraph to the externally observable recovery contract and retain its existing skills/herdr-teamlead/teamlead/report_delivery.py / source_prompt reference. Preserve required complete unchanged transcript inputs, the private-copy versus actual-delivery distinction, and the accepted modern/legacy compatibility boundary. No parser, tests, recovery behavior or authority change is proposed.

Prior work and scope

#373 covered similar Claude parser prose and was completed by #419. This is newly added Codex prose from #473, so that closed issue does not track this remaining item. #458 concerns different release-skill helpers. #441's skill-length recommendation is a separate advisory, not this defect.

This is a bounded documentation proposal for a future appropriate change. Is this direction welcome when adjacent documentation work is next needed? No implementation, schedule or dedicated correction round is promised; the advisory does not gate #473.

AI disclosure

OpenAI Codex prepared this proposal from the current policy review and independently verified reports. No human line-by-line review is claimed.

Read skills/herdr-teamlead/references/dispatch-recovery.md at lines 624–626, then consult rules/script-as-black-box.md and the existing skills/herdr-teamlead/teamlead/report_delivery.py/source_prompt reference. Shorten only the Codex paragraph to the external recovery contract while preserving complete unchanged transcript inputs, private-copy versus actual-delivery distinctions, and modern/legacy compatibility; no parser, test, recovery behavior, or authority changes should result.
