## Scope and limitations

These are machine-extracted research records, not verified trading systems. Catalog rank measures specification detail and claimed evidence, not profitability. The catalog extraction pipeline did not independently backtest these records. Its separate selected testing ledger does not validate the wider corpus. Rules, labels and parameters can be incomplete or wrong; consult the original source and its reuse terms.

No endorsement, ownership claim or source-code reuse permission is implied.

## Extraction warnings

Claim warnings: RECOVERY SIZING: position size increases after losses (martingale/grid/averaging). Equity curves look smooth until the run that does not recover - judge it on worst-case exposure, not win rate.
Opacity warnings: PARTLY OPAQUE ENTRY: 2.0 of 4 entry conditions reference a value the source never published. The rest is specified.
