nx_workmix_lib.nx -- THE WORK-MIX RULER (ecosystem EC56, 2026-09-17): what LANDED in a window, classed by what it was an investment IN. OPERATOR 2026-09-17: measure and shift our investment, through better and better estate capabilities, towards features, and reduce the rework, enablement and expansion investment that detracts from the goals we set. FEATURE a landed rung whose rungrole is contender or arm; with no rungrole, a rung on a board the class table marks product ENABLEMENT rungrole substrate; with no rungrole, a rung on an operations board. Split by whether a FEATURE rung names it in its deps (it unblocks a feature) or no feature rung does (enablement for its own sake, the class to shrink) REWORK a land row whose rung's newest EARLIER event is a retract (the claim was withdrawn and landed again); retract rows are counted beside it as events of their own. A rung that lands twice is NOT rework by that alone: a land row journals a SLICE, and slices are how a rung is climbed (the close ruler learned this the same day). UNCLASSED everything the data cannot class: no rungrole and no board class, a superseded or malformed role, a board whose plan could not be read. It is its OWN bucket and it is printed: a class the ruler guessed is a lie. the classes PARTITION the land rows of the window (their sum is printed beside the row count). ONE reader of land rows: the events come from the costcal ledger (nx_costest_lib grammar); plans are read only for what the ledger does not carry -- rungrole rows and deps. Pure: buffers and numbers in, so a gate drives it on planted rows. license_tier: ORIGINAL No hw writes (Rule 26).
