Seven-field contract
Objective, primary object, delivery surface, scope, must/must-not, authorization, and completion evidence.
Read-only Hugging Face mirror
Keep execution aligned with the task contract.
A local-first deterministic Guard for explicit action boundaries and completion evidence, with Codex and unofficial DeepSeek Harness integrations.

What the project owns
The Guard checks deterministic task-contract rules and current evidence. The Host still owns planning, sandboxing, permissions, tool execution, and user interaction.
Action gates
Structured forbidden and requires-user rules can intervene; natural-language matches remain advisory.
Evidence receipts
Current structured outcomes can satisfy exact requirements; newer failure invalidates older pass.
Operational sequence
The sequence is explanatory. Install and execute the actual project locally from its canonical repository.
01
Load contract
Validate one explicit task contract from the trusted workspace.
02
Check pending action
Classify structured tool and command signals before execution.
03
Observe result
Retain bounded, content-free evidence references and current status.
04
Check completion
Compare required evidence with current receipts.
05
Continue at most twice
Balanced mode may request bounded verification; loop guards prevent endless steering.
Evidence boundary
This page preserves the project's published limits instead of turning engineering checks into outcome claims.
Native controls remain
The Guard never weakens Host sandboxing, approval, or permission systems.
Semantic checks advisory
Only structured deterministic rules may hard-block.
No general efficacy claim
Unit and integration tests establish covered behavior, not real-world task improvement.
