Hooks that send each Claude Code tool call to a local Tracekit signer before it runs: allowed, denied with the rule that matched, or held until you approve it from another terminal. The signer signs every call, decision and result into a hash-chained record that `tracekit verify` checks offline. Needs the tracekit-ai Python package (`pip install tracekit-ai==1.6.0 && tracekit init --dev --v2 --no-hooks`). In that dev mode the signer runs as your own user; on Linux, system mode runs it as a separate user.
