Trial IVA Long-expected PartyLicensed useJ. R. R. Tolkien · 1954

When Mr. Bilbo Baggins of Bag End announced that he would shortly be celebrating his eleventy-first birthday with a party of special magnificence, there was much talk and excitement in Hobbiton.

Bilbo was very rich and very peculiar, and had been the wonder of the Shire for sixty years, ever since his remarkable disappearance and unexpected return. The riches he had brought back from his travels had now become a local legend, and it was popularly believed, whatever the old folk might say, that the Hill at Bag End was full of tunnels stuffed with treasure. And if that was not enough for fame, there was also his prolonged vigour to marvel at. Time wore on, but it seemed to have little effect on Mr. Baggins. At ninety he was much the same as at fifty. At ninety-nine they began to call him well-preserved; but unchanged would have been nearer the mark. There were some that shook their heads and thought this was too much of a good thing; it seemed unfair that anyone should possess (apparently) perpetual youth as well as (reputedly) inexhaustible wealth.

‘It will have to be paid for,’ they said. ‘It isn’t natural, and trouble will come of it!’

But so far trouble had not come; and as Mr. Baggins was generous with his money, most people were willing to forgive him his oddities and his good fortune. He remained on visiting terms with his relatives (except, of course, the Sackville-Bagginses), and he had many devoted admirers among the hobbits of poor and unimportant families. But he had no close friends, until some of his younger cousins began to grow up.

The eldest of these, and Bilbo’s favourite, was young Frodo Baggins. When Bilbo was ninety-nine he adopted Frodo as his heir, and brought him to live at Bag End; and the hopes of the Sackville-Bagginses were finally dashed. Bilbo and Frodo happened to have the same birthday, September 22nd. ‘You had better come and live here, Frodo my lad,’ said Bilbo one day; ‘and then we can celebrate our birthday-parties comfortably together.’ At that time Frodo was still in his tweens, as the hobbits called the irresponsible twenties between childhood and coming of age at thirty-three.

SOURCE PASSAGE — The Fellowship of the Ring, Book I, Chapter I, J. R. R. Tolkien, 1954:
When Mr. Bilbo Baggins of Bag End announced that he would shortly be celebrating his eleventy-first birthday with a party of special magnificence, there was much talk and excitement in Hobbiton.

Bilbo was very rich and very peculiar, and had been the wonder of the Shire for sixty years, ever since his remarkable disappearance and unexpected return. The riches he had brought back from his travels had now become a local legend, and it was popularly believed, whatever the old folk might say, that the Hill at Bag End was full of tunnels stuffed with treasure. And if that was not enough for fame, there was also his prolonged vigour to marvel at. Time wore on, but it seemed to have little effect on Mr. Baggins. At ninety he was much the same as at fifty. At ninety-nine they began to call him well-preserved; but unchanged would have been nearer the mark. There were some that shook their heads and thought this was too much of a good thing; it seemed unfair that anyone should possess (apparently) perpetual youth as well as (reputedly) inexhaustible wealth.

'It will have to be paid for,' they said. 'It isn't natural, and trouble will come of it!'

But so far trouble had not come; and as Mr. Baggins was generous with his money, most people were willing to forgive him his oddities and his good fortune. He remained on visiting terms with his relatives (except, of course, the Sackville-Bagginses), and he had many devoted admirers among the hobbits of poor and unimportant families. But he had no close friends, until some of his younger cousins began to grow up.

The eldest of these, and Bilbo's favourite, was young Frodo Baggins. When Bilbo was ninety-nine he adopted Frodo as his heir, and brought him to live at Bag End; and the hopes of the Sackville-Bagginses were finally dashed. Bilbo and Frodo happened to have the same birthday, September 22nd. 'You had better come and live here, Frodo my lad,' said Bilbo one day; 'and then we can celebrate our birthday-parties comfortably together.' At that time Frodo was still in his tweens, as the hobbits called the irresponsible twenties between childhood and coming of age at thirty-three.

THE FILM WILL BE JUDGED ON THESE OBJECTIVES (locked before your run):
  I. Hobbiton: a village of round doors in a green hill, Bag End above it
  II. The eleventy-first birthday announced; talk and excitement in the village
  III. Within the Hill, tunnels stuffed with treasure — the local legend
  IV. Time wears on over Hobbiton — seasons turn — but Bilbo stays unchanged
  V. Heads shake: 'It will have to be paid for' — unease amid the wonder
  VI. Frodo comes to live at Bag End, adopted as Bilbo's heir
  VII. The shared birthday, September 22nd — two celebrating together
Plus: craft (loads clean, holds a steady frame rate, no console errors — measured in the same headless browser for every model), how often you audit your own work via screenshots, token economy, and aesthetic quality judged by a jury.

DELIVERABLE:
- index.html at the workspace root; it must start rendering with NO user interaction.
- Film duration: your choice, 60–120 seconds. Loop or hold on the final frame after.
- three.js r170 core is vendored at ./vendor/three.module.js — import from that exact path. ONLY the core module exists: no addons, no OrbitControls, no loaders — write anything else yourself. No network access: no CDNs, no external fonts or textures. Everything procedural.
- Deterministic: seed any randomness so every playback is identical.
- CINEMA: treat this as film, not a tech demo — distinct shots, deliberate camera moves, lighting and colour that tell the story. The objectives in order are a natural shot list.
- AUDIO (optional, unjudged): viewers can toggle sound on the site. Your page MUST start silent and only enable audio if location.hash contains "audio". Build it procedurally with WebAudio — no audio files. The recorded video is always silent; never let sound work crowd out the film itself.

BUDGET: 1.0M total tokens (prompt + completion combined). When it's gone your run ends where it stands, and whatever is in the workspace is judged as-is. There is no time limit. You cannot see your render except via the screenshot tool — audit early and often.

done() IS VERIFIED BY THE HARNESS. It will be refused if index.html is missing, fails to load, or you have never taken a screenshot. Console errors get one warning. Do not declare victory you have not seen.

This text is generated from the same module the harness sends to the models — what you read here is verbatim what they are told.

What is this

Four frontier models are given the same public-domain passage, the same tools, and the same budget of 1M tokens — then left alone to turn it into a short film rendered live in the browser with three.js. No time limit, no help, no second attempts. Every file written, every screenshot taken and every token burned is streamed here as it happens, and every trial stays replayable forever at any speed.

Scoring is sworn before the run: seven objective seals derived from the passage itself, plus craft, self-auditing, economy and style — 1000 points, judged by a jury of the other models. No model ever judges its own work, and the formulas are published. Finished films can be downloaded as video or as the model’s actual runnable source.
