Candidate

bar_shannon_entropy (custom)

Frozen test constants

k=5 · binning=equal_width

Axis-2 status

defensible — Binning scheme flagged for operator confirmation (see header).

Window

Gate: PASS = |ρ|≤0.85 AND R²≤0.85 AND h_norm≥0.05 across every valid bar set. Not yet fully grounded — see verdict pill.

Most frequent worst competitors:

bar_petrosian_fd — appeared as worst competitor in 66 cell(s)
trade_intensity — appeared as worst competitor in 44 cell(s)
bar_katz_fd — appeared as worst competitor in 39 cell(s)

3 · Next steps

Iteration 2: bar_permutation_entropy (tested at m=3 · tau=1).

4 · Pending tasks

3 bar set(s) skipped (insufficient bars / empty cell).
Axis-2 final status deferred to Stage 2 (project-wide constant ratification, after the full family is evaluated).
Cross-candidate ρ/LOO-R² matrix (run_cross_candidate.py) must run before any PROMOTE — catches sibling clusters.
