Keep ANSI formatting out of persisted logs.
build_main_file_handler uses the same formatter as the console handler and does not strip escape sequences. Line 31 therefore writes ANSI codes to main.log. Use separate formatters, or apply color only in the console formatter.

- Around line 281-294: Update the database initialization/migration flow used by
mark_environment_finished and the JobEnvironment model to add the missing
job_environments.finished column for existing SQLite databases, using a default
of 0 and an idempotent migration that safely handles databases where the column
already exists. Add coverage that initializes an existing database without
finished, runs the migration, and verifies the column and default behavior.
In `@core/data_manager/yaml_aggregator.py`:
- Around line 223-254: In the job initialization flow surrounding the existence
checks and subsequent _sync_sqlite/_sync_cloud calls, acquire a durable
job-scoped claim before checking whether the job exists, and retain it until
synchronization reaches a recoverable terminal state. Ensure concurrent
launchers serialize on the same job_id so only one can create initial
environments, while preserving the existing resume, rebuild, and storage-type
behavior.
- Around line 235-245: Update the resume branch in sync_configs_to_db to detect
when the resumed job has no active environments after
_delete_unfinished_session_steps. Return an explicit no-work resume result that
the worker group can recognize, and ensure that result is reported as a
successful no-op rather than failed_no_episodes while preserving the existing
cleanup and connection return behavior.
In `@manager/simulation_worker.py`:
- Around line 280-286: Update the completion flow surrounding
mark_environment_finished so it runs only after evaluation and reward commit
have both succeeded, using the final result status rather than an earlier
success or truncation state. Ensure gateway finalization failures change
result.status to failed or an explicit partial status, preventing run_all from
reporting success while the environment remains unfinished.

Add an idempotent migration for job_environments.finished.
Existing SQLite databases without this column fail with no such column: finished. Add the column with DEFAULT 0, and test the migration on an existing database.

_resolve_session_environment()does not cache misses. After the per-session tracking was removed, this loop resolves the environment for every record.
