Client-side optimizer for Neverness to Everness console builds. Imports a gear export from nte-history-exporter, keeps it in IndexedDB, and solves for the best module placement per character or across a team. - domain/: pure ports of the Python research scripts (shapes, cartridges, board tiling, stats, scoring, set bonuses, Arc effects, sheet prediction). No DOM, no storage imports, so they stay worker-safe and Node-testable. - solver/: single-character solve with branch and bound, plus a three-phase team solve (portfolio, leximin, column generation) over disjoint item sets. Runs in a Worker when one can be constructed, inline otherwise. - db/: three storage tiers selected by use rather than feature detection, fail-closed import validation, and undo that restores both sides of a steal. - ui/: React 19 views for items, characters and teams; the board is drawn as the deliverable rather than a score. - Two build targets: a hosted bundle and a single self-contained nte.html with no external requests. Values the model cannot measure are reported as unavailable rather than guessed: cartridge set bonuses, the level 80 base-stat multiplier, and the distinction between "optimal for this packing" and globally optimal. 145 tests, tsc clean, both build targets clean.
