Short Git-tracked spec_ref with the exact P28-01 work/acceptance, the P28
cross-cutting six and BASELINE.txt line references. Collector task contract
(codex/gpt-6-astra, independent Opus review) limited to execution/p28-01/
collector/**, outside the product source map, so the formal 192-suite
evidence stays valid. Nothing registered or run; original credit unchanged.
