feat!: remove the serve CLI, rename ServingConfig to ServeConfig

[mikasenghaas]

Summary

Removes the serve CLI entrypoint: hosting an env server from the command line is the trainer's job (prime-rl's uv run env), and nothing in verifiers, prime-rl, or research-environments invokes uv run serve — the server-backed eval path already calls serve_env in-process.

• Deletes verifiers/v1/cli/serve.py, its run config verifiers/v1/configs/cli/serve.py, and the serve console script.
• Renames ServingConfig → ServeConfig (the name the CLI config freed up): the reusable [serve] block — pool, address, max_concurrent — read by whoever hosts an env. serve_env, pool_serve_kwargs, and the eval CLI's [serve] block are unchanged apart from the type name.

Breaking

• uv run serve is gone. Host an env server programmatically via serve_env, or through a trainer (prime-rl's uv run env, one server per source).
• vf.ServingConfig is renamed to vf.ServeConfig (same fields: pool, address, max_concurrent). The CLI-only ServeConfig (env + serve + legacy + verbose/dry_run) is removed with the CLI; it was not exported at the verifiers.v1 top level.

Note

Remove the serve CLI and rename ServingConfig to ServeConfig

• Deletes verifiers/v1/cli/serve.py and removes the serve console script entry point from pyproject.toml; the serve command can no longer be invoked via the package.
• Renames ServingConfig to ServeConfig in verifiers/v1/configs/serve.py and updates all imports and __all__ exports across the package.
• Removes ServeConfig from verifiers.v1.configs.cli since the CLI config module for serve is also deleted.
• Risk: breaking change — any code importing ServingConfig or invoking the serve CLI entry point will break.

Note

Medium Risk
Breaking API and CLI removal affects any external scripts using uv run serve or importing ServingConfig; in-repo eval/server paths only need the rename.

Overview
Breaking: Removes the standalone serve console script and the entire uv run serve CLI (verifiers/v1/cli/serve.py plus verifiers/v1/configs/cli/serve.py). Hosting an env server is expected via serve_env in-process (e.g. eval --server) or through trainers such as prime-rl’s uv run env, not a dedicated verifiers CLI.

Renames the shared [serve] pydantic block from ServingConfig to ServeConfig in verifiers/v1/configs/serve.py, with matching import/__all__ updates (including EvalConfig.serve). Field semantics (pool, address, max_concurrent) and helpers like pool_serve_kwargs / serve_env are unchanged aside from the type name. Docs in pyproject.toml now list validate instead of serve among default v1 CLIs.

Callers must stop using uv run serve and replace ServingConfig imports with ServeConfig.

Approvability

Verdict: Needs human review

This PR removes the serve CLI command entirely, which is a breaking change to the public API. While the rename from ServingConfig to ServeConfig is mechanical, removing a public CLI entrypoint warrants human review to confirm the intended deprecation path.
