NOTICE IN · RECOVERY OUT
One failed-inspection notice becomes an active recovery.
Mettle preserves the notice’s explicit proof instructions. When proof is not specified, it asks the contractor before outreach.

CONTRACTOR-REVIEWED HANDOFF
Reinspection packet
Mettle assembles the evidence. The contractor reviews and releases it.
EVIDENCE COVERAGE
What is ready
Nothing is released until the contractor approves it.
RUN RECEIPT · SANITIZED · READ ONLY
What acted, what paused, and why.
Inspectable Strands control flow, safe outputs, and contractor boundaries—without prompts, private reasoning, credentials, or runtime identifiers.
ORCHESTRATION AT A GLANCE
What runs, what wakes it, where it stops.
Each step names its role: model agent, deterministic policy, or contractor decision.
Bounded authority: models interpret language and visible evidence; they never decide deadlines, gates, or what Mettle may claim.
