π 41 candidates are substrate-blocked (need intra-bar per-quote / per-tick / bid-ask-path / price-path data that forex_bars does not persist) — runnable corpus = 36 substrate-clean. View the substrate-blocked board →
A fully-provenanced shortlist of parameterless-by-inspection, computable-on-our-data, candidate features for the forex strategy (EURUSD / GBPUSD / XAUUSD). Every row carries a FOSS implementation reference, an SPDX license verdict vs the MIT host, a stable paper ID, and a git + chronicle provenance anchor. Empirical orthogonality (Spearman / Chatterjee ΞΎ / CODEC) is the deferred numeric battery.

Post-audit corrections (challenged-and-held, 2026-06-05) β a two-agent adversarial audit (4 HELD / 6 PARTIAL / 4 CONCEDED) reclassified #33/#34/#35/#36 OUT-OF-SCOPE (the FXView quote-only substrate has no trades/volume), narrowed #117 to the |ΞT| magnitude (sign duplicates #46), and flagged #42/#43/#45/#118 paper-ID β£ PENDING. Net: 118 not-covered, but the effective grounded-and-computable slate β114. Gates G1 (per-tick store anchored), G2 (canonical sign-word), G3 (min-quote-count guard) are pinned; G4 (re-examine near-shipped composites vs shipped columns) is deferred to the numeric battery.
FOSS & licensing β 64 permissive (MIT/BSD/Apache/ISC/NCSA β vendorable), 43 copyleft (reference-only β clean-room reimplement), 13 unverified. The deliverable ships no third-party code (research markdown + a future clean-room Rust port), and a mathematical statistic is uncopyrightable, so all candidates are deployable MIT-clean. Every FOSS reference below links to its upstream repo.
Provenance & chronicle cross-check β git-anchored not-covered vs compute_features_v2@c803ef96e + schema.sql@2d308f1c, then re-verified against the prior 2026-05-26/27 forex orthogonality-eval Gate chronicles (52 files). That cross-check excluded 2 forex duplicates (#73 spectral-entropy β shipped; #32 quote-revision-imbalance β dropped at Gate 8-FP.1). Detail β
