Capture the Sean's AI Stories loop-engineering video in the TAC meta-prompt. Require plans to name harness context, memory, guardrails, traces, evals, and promotion criteria, and lock those markers with pytest.
Add the TAC Product Factory, signed deploy action contract, Plan F3 artifacts, RSI evidence metadata, and loop-engineering meta-prompt. Vendor the Plan F3 skill, add product receipts/dashboard output, and cover deploy/plan/product invariants with pytest. Keep broader auto-patch claims guarded behind degraded-skill recovery receipts while preserving canary evidence.
