Blast Radius Zero is a dsh plugin bundle (dsh-plugin-blast-radius) that turns the DeepSeek Harness into a control plane for untrusted work. You give it a repository and a goal; it plans a job, and every command that job needs — installing dependencies, compiling, running a test suite, running scanners — is dispatched into a disposable Microsandbox microVM that exists for that job and nothing else. The agent touches the code, never the machine. Why the boundary is the product: an agent that modifies a codebase runs dozens of binaries nobody wrote, some of them hostile. Process isolation, secret hygiene, resource caps and lifecycle discipline are enforced on every exec: host credentials never enter the microVM, the egress allowlist only ever attaches the inference key to api.vultrinference.com, and the VM is destroyed when the task ends. Verifiable output, not prose: before and after a run, eighteen metrics are measured (source lines, dependencies, CVEs, test count, coverage, peak memory, wall time). Every row carries the command that produced it, its exit code and a SHA-256 of the output, and every tool call is appended to a hash-chained receipt log, so a finding can be replayed and a claim checked instead of believed. On Vultr: Cloud Compute (VX1) hosts the stack, nginx terminates TLS on 443 and proxies to the dsh web UI on loopback, Serverless Inference at api.vultrinference.com/v1 serves the agent's model calls, and the Vultr API v2 provisions and destroys throwaway instances. Stack: TypeScript on Node 22, zero runtime dependencies, a Python sandbox runner, 92 automated tests, MIT licensed. Status: the tree is complete and green offline (18 verify checks, 63 gate checks, 92 tests, receipt chain head 15a413244d15). The public demo box, the domain and the recorded containment moment are the three steps that need a Vultr account and a KVM host, and each is listed with its blocker in docs/BLOCKED-EXTERNAL.md.

🌎 Hybrid Hackathon | 💻 Online Build: 3–8 November 2026 | On-site Phase: 8 November 2026 📍 On-site Venue: Pierpont Place 163 W Pierpont Ave, Salt Lake City, UT 84101, USA ✨ Please note that travel and accommodation are not covered.

🌎 Online Hackathon | 💻 Online Build: Sept 26 - Oct 5, 2026 A virtual, global hackathon. Build from anywhere in the world. Dark Factory is the official hackathon of WeAreDevelopers World Congress North America, presented by BAND, but you don't need to be in San Jose to take part. For one week, you build a software factory in BAND Desktop: a band of coding agents that plans work, implements it and checks its own results. 🎟️ Bonus for sign-ups: you are eligible for a free ticket to WeAreDevelopers World Congress North America in San Jose (Sep 23–25). If you do go, stop by the BAND booth: a surprise is waiting for you.
