What changes

"The language" was checked feature by feature against ledger/, and the ledger won where they differed. The rest of the README reads in shorter sentences.

Added, each with a short example that compiles (and, where it prints, a // what it shows that the test holds against Simulate):

• New sections: Numbers with a fraction (fixed, Math.sqrt, hypot, sin, cos, tan, atan, atan2, rounding, decimals in a printed text), Functions as values (kept in a variable, an array, a field or a Map; closures), Errors (try, catch, finally, throw, classes of error, e.stack, a stack overflow as a RangeError), Events (on.created, died, killed, morphed, order), Sounds (playWav, tone, noise, pluck, fm, silence, effects, mixdown, together, sounds.Name), Files the script imports (.video, .image, .sound, .notes, cover()), The standard library (math, random, timers, signals, ui, cutscene, fog, screen, music; reserveLocation).
• Time and edges became Waiting and tasks: async/await, nextFrame, until, start() and tasks, Promise.all/race/any, .then, generators, for await.
• Functions return records, tuples and arrays; optional parameters; a nested function sees the outer function's locals.
• Classes in any file, type parameters, protected, instances kept by reference.
• Input: keyHeld, on.key, on.chat, local.*, await sync(), select(), centerLocation with a size.
• memory.game.frame, memory.map.*, memory.vision.countdown.
• Arrays: shift, unshift, splice, at, lastIndexOf, join of numbers. Texts: split, replace/replaceAll, trim*, upper and lower case, charCodeAt, parseInt, isNaN, a boolean in a text, lines of JSX.
• number | undefined, players in variables, labels, const enum, namespace, comment(), a Map keyed by a union of texts.
• The front matter links the guide's new TrigScript and eudplib page (TrigScript guide: four pictures, a table beside eudplib, plainer sentences scm-js#77).

Corrected:

• TrigScript beside TypeScript, row by row.
• What a program does not have, rebuilt from refusals checked with the compiler. The stale "Still to come" paragraph naming docs/eud-plan.md is gone.
• "The game reports no held key": keyHeld exists.
• Input is carried by the map on the own build. A script built through eudplib still uses MSQC and chatEvent, and the README says what each takes from the map.
• A program's texts go into the built map's string table by the build, not "by eudplib".
• A function declared inside another sees the outer function's locals. const b = a copies an array.
• Class limits that no longer hold: one class per array, a variable never given another instance, waves.push(w) refused, no type parameters on a class.
• displayText(text, false) follows the player's subtitle setting.
• The "1700 slots" sentence, which contradicted "a loop costs what the map holds".
• For other plugins and the compiler section no longer say eudplib builds the map.

Not verified

• chatted's {n} "up to 1 048 575" may be the MSQC limit. On the own build the limit depends on the map's size.
• What the own build's input takes from the map comes from the plan's step 12, not from a game run.
• program()'s hover in compiler/declarations.ts still says programs are built by the eudplib plugin. Out of scope here.
• The link to docs.scmjs.dev goes live with the next scm-js release that publishes the docs.

Checked

• npx vitest run tests/readme.test.ts: 46 passed (30 before).
• npx tsc -p tsconfig.json: clean.
• The one ```tsx example (lines of JSX), which the README test does not read, was compiled and simulated by hand.
