The nine-day sprint
294 commits in nine days: the Vibe system, the first Hash Drift, a compiling orchestrator and a Unity apartment. Most of it written by AI agents.
Written after the fact, from the commit history and the design logs.
From November 10 to 18 the repo took 294 commits. That pace needs explaining: the project had just set up ten AI development agents and six QA agents, with git worktrees so they could work in parallel without stepping on each other. A solo developer with a small synthetic team.
What landed in those nine days:
- The Vibe system, database schema through API. Vibe is the non-tradeable reputation layer; it survived every reset since.
- The Dr1ftS0und tables: cassettes as on-chain collectibles, a plan the full game still keeps.
- The first implementation of Hash Drift, the permanent record of what you did. Thirteen action types, from ChallengeSolved to Caught, each entry chained to the previous one with SHA-256. The commit message gave it its motto: “Your Hash is Your Soul”.
- The match orchestrator went from 119 compile errors to zero in one session. A few days later the blockchain library was swapped from ethers to Alloy, and the license went from MIT to proprietary.
- On the Unity side: the starter apartment scene, a player controller, and code-based generators for the apartment, desk, laptop, chair and bookshelf. Plus a low-poly NPC set, five archetypes with twenty clothing variations, under 500 triangles each.
One honest footnote, found a year later. That first Hash Drift stamped every entry with the wall clock and a random UUID, which means no run can ever be replayed and verified. You cannot reconstruct the same chain twice. When Drift Core needed replayable transcripts, that is the first thing that had to be rebuilt. The chain on our home page is deterministic for exactly that reason.
