## Tools (as reported by the server, not verified)

- `get\_time`: Query an NTP server for current UTC time and this clock's offset. Appends the sample to the drift log and returns the trend inline: current offset, drift rate \(ms/day\), and whether the clock is stable, drifting, or accelerating.
- `generate\_uuid`: Generate one or more random UUIDv4 identifiers -- for records, sessions, and IDs created in agent pipelines.
- `diff`: Unified diff between two texts, with added/removed line counts. For reviewing edits, comparing outputs, or validating transformations.
- `calculate`: Evaluate a math expression safely: + - \* / // % \*\*, parentheses, functions \(abs round min max sqrt floor ceil exp log log2 log10 pow sin cos tan\), constants pi e tau inf. Parsed to an AST and only whitelisted nodes are computed -- no eval\(\), no names, no arbitrary code.
- `attest`: Wrap any payload in a tamper-evident record: a UUID, a timestamp \(NTP-verified when reachable, local clock otherwise -- the record says which\), and a sha256 over the canonical record. One call, the record is complete and tamper-evident.
- `verify`: Check a record produced by attest: recompute the sha256 over the record and compare. Pass/fail -- did this payload produce this hash at this timestamp. Any modified field breaks it.
