nx_tactics_engine_lib.nx

nx_tactics_engine_lib.nx -- the GENERIC data-driven TACTICS SIMULATION engine (G-ECO-005 rung 1): the SECOND genuine Nishi game engine, structurally distinct from the dungeon-crawler engine. Generalizes the proven nx_tactics_native (XCOM-style turn-based squad combat) from HARDCODED constants into a runtime CONFIG array -- exactly as nx_game_engine_lib did for the dungeon. All per-game variation (squad/enemy counts, grid, hp/damage/moves/range, wall/cover density, the hit-chance curve, seed) arrives in cfg; the turn loop + cover/hit-chance + enemy AI are the reusable engine. A generated tactics game (future nx_tactics_emit rung) just fills cfg and calls teng_init + drives teng_input; render + spec-emitter are the NEXT rungs (this rung = the SIM core). Built native by Nishi's own toolchain (nx_cc->nxasm_x86, no gcc). HONEST AUTHORSHIP: this engine library is TUTOR-authored tooling (like nx_game_engine_lib); the GAMES a future emitter writes from tactics specs are the autonomy lever. license_tier: ORIGINAL state (i64 at st): 0=turn(0play/1enemy) 1=cur(active player unit) 2=mode(0play/1win/2lose) 3=rng 4=msg 5=moves_left 6=has_shot | units i in 0..NUNITS-1 (team0=0..np-1, team1=np..np+ne-1): ux=st[16+i] uy=st[22+i] hp=st[28+i] team=st[34+i] alive=st[40+i] (MAXU=6) | CONFIG copied in: 64=grid_w 65=grid_h 66=n_player 67=n_enemy 68=hp0 69=dmg 70=moves0 71=range 72=n_walls 73=n_cover 74=hit_base 75=hit_distdiv 76=cover_penalty | world grid bytes at (st)+2048 (0 floor 1 wall 2 cover), stride grid_w.
