# 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.

The 2026-07-17 post-stop re-entry decision is preserved in
`daily_reentry_matrix.json`. It is the canonical source for the nine-policy
daily replay, production-like full-universe ranking, the disjoint 2025+ book,
and the cost/capacity sensitivity matrix. The interpretation and production
decision live in
[`docs/research/post-stop-reentry.md`](../docs/research/post-stop-reentry.md).

The earlier `post-stop-reentry-20260717.json`,
`post-stop-cooldown-sweep-20260717.json`, and
`gate-protected-stop-20260717.json` reports were removed as superseded
intermediate experiments. They used weekly/hybrid entry cadence or tested the
rejected stop-adjustment path, and add no decision evidence beyond the final
daily matrix and narrative. Their matching one-off runners were removed too.
All remain recoverable from Git history. Rebuildable candidate pickle caches
are intentionally ignored and must not be committed.

### Phase B fip breadth IC (2026-07-18/19) — compact evidence

Canonical artifacts:

- `fip-reconcile-20260719-000520.json` — single-sourced authoritative ICs
  (unconditional liquid fip, tiers, prod-subset, mom-conditional, context
  signals). Membership symbol dumps stripped after the decision; narrative in
  [`docs/research/fip-breadth-ic.md`](../docs/research/fip-breadth-ic.md).
- `fip-breadth-20260718-211440-fingerprint.json` — prod-snapshot fingerprint
  pass (fip IC −0.045 / t −2.91).

Removed as superseded / dangerous intermediate noise (recoverable from Git):

- `fip-breadth-20260718-211440-breadth.json` (+ wrapper) — **orphaned** +0.0575
  / t +5.12 from racing a partial `research.sqlite`. Kept out of the tree so it
  cannot be re-mythologized.
- `fip-breadth-20260718-194828*.json` — fingerprint-only partial run.
- `fip-breadth-diagnostics-20260718-213705.json` and `…-213908.json` — dual-path
  diagnostics superseded by the single-sourced reconcile.
