"""CLI wrapper for target_revenue.effort_calculator (WP-0010-T02).

Prints a proposed `phase.target_basis` estimate for a repo, with full
derivation and warnings, as JSON. Token counts are caller-supplied (e.g.
pulled from the state hub's `get_token_summary` beforehand) rather than
fetched here — this script has no MCP client of its own, matching the
offline-first design of the rest of this library.

Does not select a Target Multiple and does not register anything with
the hosted Trust Service — this is an estimation aid, not a Phase
declaration tool (that remains `scripts/trf_onboard.py`).
