nx_featuremine.nx -- FEATURES-CLASS MINER over the frontier- plane (miner-sota F1016, 2026-07-23). The census (nx_minecov MC05) measured features COVERED-but-UNMINED: nx_frontier_board derives CPM (ES/EF/float/critical-path/READY/BLOCKED) over the DAG, but nobody mines the BACKLOG ITSELF. The signal CPM does not give is DEPENDENCY IN-DEGREE: which feature BLOCKS THE MOST OTHERS. A row with float 0 is on the critical path; a row with in-degree 9 is a BOTTLENECK -- different questions, and the second is what tells a PM where to put people. Also: per-owner load with a real done-rate, status distribution, unowned rows, and BLOCKED (a dep that is not yet D) kept distinct from READY. ★HONEST LIMIT DECLARED IN THE OUTPUT: frontier ids are F-numbers, NOT epochs, so AGE IS NOT DERIVABLE from this plane -- the organ reports aging_available:0 rather than inventing a number. Composes nx_sovjson_lib (sj_*). Read-only.
