Plan: (1) lib/tea_cs_bridge.ml — new Wasm module, same API surface as tea_bridge.ml, 7 msgs (0-5=select class, 6=confirm), update: selected_tag=msg+1, selected_tag 1-6=class highlighted, 7=navigate. (2) lib/dune + bin/main.ml — add cs-bridge subcommand and update which_arg/interface/verify-bridge. (3) IDApTIK: AffineTEARouter.js+.res add screenJessicaCustomise=6. (4) CharacterSelectScreen.res: csTeaBridge module-level ref, card click handlers → teaDrive, applyView syncs Wasm→ReScript selectedClass, confirm → AffineTEA.update+navigate via showScreenWithTag. Seam check: push TitleScreen→CharacterSelect, select class, confirm→JessicaCustomise, back-stack correct. 173/173 tests currently passing."

Stage 10: tw_interface.ml multi-module boundary verifier (LinearImportCalledMultiple, LinearImportDroppedOnSomePath, CLI interface+verify-bridge cmds). Stage 11: source-level Cmd linearity — Cmd[ClickMsg] bracket syntax, quantity_of_ty_annotation returns QOne for Cmd[_], infer_usage_block declares QOne locals before subsequent stmts so uses tracked, fires LinearVariableUnused when Cmd dropped; builtins cmd_none+cmd_perform in typecheck/resolve/interp.

 session-note-2026-04-11-h = "STAGE 5 (AFFINATEA DRIVES SCENE) COMPLETE: teaDrive(engine, msgTag) is the single entry point from all 4 button handlers — update → applyView → navigate. applyView reads selected_tag via getSelected() and alpha-pulses the chosen button (0.65 → animate 1.0 over 0.22s). teaBridge loaded asynchronously on first show; graceful fallback to direct ReScript navigation when bridge is None. resize handler calls AffineTEA.setScreen(tea, width, height) to keep screen_w/h in sync with canvas. Button handlers reduced to single teaDrive call each. Navigation decision comes FROM Wasm state (selected_tag), not from button identity. Credits button wired (msgCredits) with TODO screen.
