Project · Write the spec for the project you will build

Pick one of the six projects in this course and write its full spec before any code: claim.md with the blanks unfilled, done_when.md with a five-minute verification path a stranger could follow, a corpus smell-test result, and a cost estimate from a 10-document sample. Submit the four files plus one paragraph on why you chose that project over the others.

• claim.md — the sentence with the blank, the measurement procedure, and the falsification line.
• done_when.md — observable behaviour plus the five-minute stranger verification path.
• Corpus smell-test output showing >60% of documents share an entity.
• Cost estimate extrapolated from a 10-document sample, with a hard spend ceiling set.

• The claim names a baseline and a stratification, not just a metric.
• The finish line is observable behaviour; a stranger could verify it without reading code.
• The falsification line states a concrete result that would mean the project failed.
• The cost estimate is derived from a measured sample, not guessed.
• The chosen project is justified against the dependency chain, not picked at random.
