The reason for a state other than active. The library's reasons are
catalogue words (source_not_persisted, source_unreadable,
legacy_inactive, legacy_owner); a host's reason is the text it gave.
Who recorded the state.
Unix epoch milliseconds of the last state change.
Optional writeThe id of the write that set this state, when the row carries one.
The request this process holds for the tool: the stored one when it could
be read, else the one derived from the source, else null. A state change
that names no request leaves the stored column as it is.
A tool's state as this process holds it. It mirrors the tool's row in
agentos_emergent_tool_state, except forrequest, which can benullwhile the row stores a request this release cannot read.
