fix: Resolve TOML config field placement error for prime-rl (#607)

[gspeter-max]

Summary

Fixes #607 - Resolves Pydantic validation error when running uv run prime-rl @ configs/prime-rl/wiki-search.toml

Problem

When running the prime-rl trainer with the wiki-search config, users encountered:

pydantic_core._pydantic_core.ValidationError: 2 validation errors for RLConfig
orchestrator.mask_truncated_completions
  Extra inputs are not permitted [type=extra_forbidden]
orchestrator.zero_truncated_completions
  Extra inputs are not permitted [type=extra_forbidden]

The config file had mask_truncated_completions and zero_truncated_completions nested under the [orchestrator] section, but the prime-rl package's RLConfig expects these fields at the top level of the TOML config.

Solution

Moved the two fields from the [orchestrator] section to the top level of configs/local/prime-rl/wiki-search.toml, aligning with the prime-rl package's RLConfig dataclass structure.

Changes

• File Modified: configs/local/prime-rl/wiki-search.toml
• Change: Moved mask_truncated_completions and zero_truncated_completions from [orchestrator] section to top level
• Impact: Resolves Pydantic validation errors, enabling users to run prime-rl with this config

Verification

• ✅ Config loads without TOML syntax errors
• ✅ Both fields are correctly at top level
• ✅ Fields removed from orchestrator section
• ✅ All other config files (23 total) verified - no other files affected

Test Plan

After this fix, users can successfully run:

uv run prime-rl configs/prime-rl/wiki-search.toml

The config structure now matches the prime-rl package's RLConfig expectations.

Note

Low Risk
Config-only change that just rehomes two fields; low risk aside from potential behavior differences if another loader previously relied on the old nesting.

Overview
Fixes a config schema/validation issue in configs/local/prime-rl/wiki-search.toml by relocating mask_truncated_completions and zero_truncated_completions from the [orchestrator] table to the top level so they match the expected RLConfig shape.
