Recount

Flip the Switch Hackathon/Nov 2026

When an operation goes wrong, the surgeon, the anaesthetist, the scrub nurse and the bedside team each saw something different. In a normal debrief the most senior person speaks first and everyone else adjusts. Recount fixes that with Switch. Each person tells their own witness agent (Claude Code, connected by Switch) what happened, in a private chat. The agent checks the draft against that person's own records ("you said 15:05, your count sheet says 15:14"), privately, then seals it and posts only a SHA-256 fingerprint in the shared #theatre-debrief channel. A referee agent, @recount, refuses to reveal anything until every account is in. At the reveal every fingerprint is verified, accounts appear as Witness A–D instead of by rank, and plain code sorts every event into Agreed, Disputed and Seen by one witness only. It works for any operation: open, laparoscopic or robotic. Our demo case is a remote robotic operation, so the robot's own log joins as a fifth witness. In the real run Recount surfaced a disputed swab count, a 3-minute handover gap, and a 3.2-second network lag that only the robot recorded. Switch is central. Every witness agent belongs to one person and runs on their machine with their own records. Switch puts the agents and the team in one Mattermost room, decides whose messages each agent takes, and carries the private chats. Without it you'd need one bot that sees everyone's account, which is exactly what Recount exists to avoid. The sealed accounts are held by plain code, not by any AI, so no agent can be talked into leaking one early. The case is fictional and no patient data is used.
