Subject: [PATCH] malkhut(docs): fee correction + Fable spec status + 5000-eval
 results

README updated with:
- Fee correction table (10x bug fixed, source of truth documented)
- All prior policies flagged as suspect at correct fees
- 5000-eval partial results: best=15,080 at gen 105, still climbing
- Fable's spec (SPEC_MALKHUT_ACTUALS_INTAKE.md) acknowledged:
  - Fee bug fixed (commit 5523be1d)
  - Two-mode architecture (EXPLORE + RECOMMEND) understood
  - ANNEX A and DAAT understood
  - Ecology stays (actuals calibrate, ecology plays)
  - Outstanding items logged for future sessions

Total: 20 commits, 1186 tests, all green.

+### Fee Correction (CRITICAL — all prior training was at 10x too-cheap fees)
+
+Source of truth: `dolphin.trade_execution_quality` (8006 rows, avg taker=5.016 bps).
+
+| Venue | Old taker (WRONG) | Correct taker | Old maker (WRONG) | Correct maker |
+|-------|-------------------|---------------|-------------------|---------------|
+| BingX | 0.5 bps | **5.0 bps** | -0.2 (rebate) | **+2.0 (POSITIVE)** |
+| Binance | 0.4 bps | **4.5 bps** | -0.2 | -0.2 (UNVERIFIED) |
+| Bybit | 0.06 bps | **5.5 bps** | -0.01 | -0.1 (UNVERIFIED) |
+
+**Every policy trained before this fix is suspect** — cheap fees reward overtrading.
+Re-measurement at correct fees is required for production deployment.
