# tier4_qa_compressed_fix

## v1

**Why this iteration:** Lifted from `docs/MMA_Support/Tier4_Utility.md:6-7` (the "financial firewall" framing — Tier 4 solves the cost of feeding massive traces back into mid-tier models) + `docs/MMA_Support/Tier4_Utility.md:17` (the "20-50 token surgical string" output spec). Together: Tier 4 is a stateless translator, not a full diagnosis.
**Source:** `docs/MMA_Support/Tier4_Utility.md:6-7 + 17`

**Lifted:** 2026-07-02 (scavenge pass — directive library expansion from unread markdown in `docs/MMA_Support/`)
