CAPABILITY MAP
Current public capabilities.
Capabilities are described without shipping implementation details into the browser.
Run
Curated workloads are invoked through the shared adapter/worker layer rather than arbitrary browser shell commands.
Validate
Exact outputs and reference comparisons remain part of the evidence chain.
Claim boundary
Performance improvements are treated as machine- and workload-specific until reproduced. Public presentation should not turn a development timing into a universal speed claim.
