# Backtest report index

Reports dated 2026-07-11 or earlier are the historical production research
record and remain untouched.

The completed 2026-07-12/13 S/R and Gate Target Ladder research is preserved as
compact decision evidence instead of full per-arm replay output:

- `sr-v2-validation-comparison.json` and `sr-v2-validation-cohorts.csv` record
  the held-out detector comparison.
- `sr-full-production-vs-candidate-comparison.json` and its cohort CSV record
  the full-period clean-structure replacement decision.
- `sr-explicit-target-ladder-comparison.json` and its cohort CSV record exact
  GTL parity: 202,765 candidates, 1,086 qualified setups, 321 book trades,
  Sharpe 2.03, CAGR 50.0%, and max drawdown 21.4% in both arms.
- The three `backtest-20260713-gtl-*.json/.md` pairs record the tuning,
  confirmation, and strength-sensitivity decisions. No stable improvement was
  found, so the production GTL stayed frozen.

The large `backtest-sr-*.json` replay files were removed after consolidation.
They duplicated hundreds of thousands of candidate rows while adding no
decision information beyond the compact comparisons and the narrative in
`docs/research/sr-levels-and-exits.md`. The original raw files remain available
in Git history if a forensic reconstruction is ever necessary.

The initial untracked `backtest-20260712-sr-detector-rewrite.json` is local-only
and is intentionally not part of the repository.
