nx_lbclimb_lib.nx -- THE ONE climb ruler (search R0d, ecosystem EC62, 2026-09-17): does a board's DECLARED ladder reach the leader of the public leaderboard it names, and which rank does each declared gate reach? WHY. The operator asked "what ladder do we need to climb to beat rank 1" and a seat answered by hand, staging the rungs with accept numbers NO rung had pre-declared. The estate already held every input as DATA -- the leaderboard rows (<dom>.leaderboard, nx_leaderboard_lib) and the dated targets and rung roles (<dom>.plan, nx_ladder_lib) -- and lacked only the JOIN and one datum: the score each contender rung must reach on the board. This lib is that join. climbboard|<board>|<sotatarget id>|<note> which leaderboard board measures which target climbgate|<rung>|<board>|<floor>|<basis> the rung's accept floor on that board: a score (22.9), a single dash (declared UNMEASURED) or the word leader (strictly above the leader of the day, so the gate moves when the public board does) The floor is never the last field, so a CRLF-terminated row parses (the trailing CR lands in the prose). POPULATION: the rungs whose rungrole row says contender toward the board's target. PARTITION (the CLI prints it): contenders = gated + ungated + nogate + badfloor. A climbgate row naming a rung outside that population is a STRAY: counted, never voting (a gate planted on a substrate rung cannot make a ladder reach). VERDICT: REACHES when at least one gated contender's floor is strictly above the leader; SHORT when numeric gates exist and none clears the leader; NOGATES when no contender carries a numeric gate; NOBOARD when the leaderboard holds no rival row for the board; BADTARGET when the climbboard row names no declared sotatarget. SHORT is the forcing verdict: the declared ladder cannot reach the target whatever ships, so the board owes a rung whose gate does. Pure over two buffers (plan, leaderboard): the gate drives it in-process; the CLI, the goal mapper and the emitter compose it and never re-derive it. license_tier: ORIGINAL. No hw writes (Rule 26).
