## 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

Opacity warnings: OPAQUE ENTRY: every entry condition reads a value out of something the source never defined -- a custom-indicator buffer, an iCustom() call, or an author-named score. The rule names the signal without specifying it, so it cannot be reproduced bar-for-bar from this record.
