"""tht CLI -- Typer app `tht`.

Minimal skeleton for now: registers `phase_app` (the gate needs `tht phase meta --json`).
Other command groups (db, schema, lsh, vector, memory, session, decision, sql, cte,
evidence, search) are wired in their porting tasks, once their backend deps land
(A9 ports db/mschema/_guards; B1 ports vectorstore; B3 ports search/lshindex/sampling).
