atlas-orchestrator: a verification gate for Claude Code

Field notes

The plugin freezes a task packet before implementation, including the intent, ordered success criteria, scope, verification command, and baseline. Its ledger stores each transition under .atlas/<run_id>, allowing an interrupted run to resume rather than restart. The visible example records a parse_duration change, with the harness reporting a mismatch for Arabic-Indic numerals and forcing a refinement pass despite the initial gate result.
