Audit Pile
Answers 'who approved this' from a folder of exported approval emails. Built for Receipts — build something that makes a messy pile of documents answerable. Thread reconstruction and approval-chain extraction. The interface is deliberately narrow: one path, done properly, rather than a broad surface that half-works at the deadline.

On the clock
What shipped, what didn't
Completed in time
Thread reconstruction and approval-chain extraction.
Unfinished / faked
Breaks on forwarded threads with trimmed quotes.
Obstacles
Spent too long on the data model and had to build the interface in the last eight minutes.
Lessons learned
Test the demo path once at minute 25. I didn't, and it showed.
Process
Prompting approach
Started from a single system prompt describing the user and their constraint, then iterated with the assistant on the Audit Pile data model before writing any interface code. Full prompt log is in the repository under /prompts.
Fairness
Disclosures
Declared by the builder at submission time, visible to judges before scoring.
Judging
Public feedback
Judges' private notes stay private — this is what they chose to say publicly.

Nice work under the clock. The unfinished list is longer than the finished one, but what shipped works and you were straight about it.
