Trigger Script

scm-js/plugin-trigger-script, installed from Browse Plugins, is the Script Editor: a TypeScript-subset language kept as a file inside the map (scmjs\triggers.ts, with a build manifest in scmjs\triggers.json) and compiled into a block of the trigger list. It used to be part of the editor and was moved out so the editor no longer carries Monaco and a second TypeScript; the plugin fetches both from a CDN when the dialog first opens (Monaco as jsDelivr's bundled ESM build, TypeScript into a blob worker with a main-thread fallback). It is the worked example for api.triggers.claim — the manifest holds a hash of the generated records, locate looks for them at the recorded start and then anywhere in the list, so the Trigger Editor badges and locks the block wherever local edits moved it, and a hand edit inside it makes the block stale (ordinary triggers again; the next Build appends a fresh one) — and for a plugin publishing commands for other plugins: trigger-script.state, .declarations, .compile, .build, .print, .simulate, .triggerAtLine and .open, which the AI plugin calls through api.commands.run after checking commands.has, listening to the "commands" event since plugins activate in no fixed order. Its source keeps the compiler out of the browser-specific parts (compiler/ is pure, tested under vitest with the real typescript package, and vendors the trigger tables it reads), which is what lets the same modules run in the worker.
