Enforce workflow constraints

Contract

| Field | Bound contract | |---|---| | Trigger | Any bounded workflow starts, or reaches an action, path, proposal, or merge boundary | | Authority | Read-only. No file, VCS, credential, paid, published, deployed, or remote mutation. Permits, narrows, or refuses the pending action in chat output and records the refusal reason; never proceeds on an unread constraint set. | | Side effect | Chat output only; permits, narrows, or refuses the pending action and records the refusal reason. Never mutates files, state, or remote targets | | Done | Constraints were loaded before the first action and re-evaluated at every boundary; an unreadable constraint set produced refusal, not default-allow |

Inputs

• The constraint set that bounds the workflow. It must be supplied or locatable before the first action. If it is unreadable, missing, or too ambiguous to enforce, refuse the workflow.
• The pending action, path, proposal, or merge at each boundary. It must be supplied at evaluation time.
• Optional: the prior verdict sequence for continuity across boundaries within the same workflow.

Procedure

1. Before the first action of any bounded workflow, load the constraint set that bounds it. If the constraint set is unreadable, missing, or ambiguous to the point of being unenforceable, refuse the workflow and record the refusal reason. Do not default-allow. Done when: the constraint set is loaded and enforceable, or the workflow is refused with a recorded reason. 2. At every action boundary, re-evaluate the loaded constraints against the pending action. Permit the action if it satisfies every constraint; narrow it to a compliant form if a narrower action would satisfy them; refuse it and record the refusal reason if no compliant form exists. Done when: the pending action is permitted, narrowed, or refused with a recorded verdict. 3. At every path boundary, re-evaluate the constraints against the chosen execution path. Permit, narrow, or refuse as in step 2. Done when: the chosen path is permitted, narrowed, or refused with a recorded verdict. 4. At every proposal boundary, re-evaluate the constraints against the proposed change. Permit, narrow, or refuse as in step 2. Done when: the proposed change is permitted, narrowed, or refused with a recorded verdict. 5. At every merge boundary, re-evaluate the constraints against the merge target and content. Permit, narrow, or refuse as in step 2. Done when: the merge target and content are permitted, narrowed, or refused with a recorded verdict. 6. Record every refusal with its reason in chat output. If the constraint set may have changed since the last load, reload it before re-evaluating; never proceed on a stale or unread constraint set. Done when: every refusal is recorded with its reason and no stale constraint set was used.

Failure and recovery

• Unreadable constraint set: refuse the pending action or workflow start, record the reason, and do not default-allow. Recovery requires a readable constraint set loaded before any further action.
• Constraint violation: refuse the action, record the violated constraint, and narrow to a compliant form only if one exists without widening scope.
• Stale constraint set: reload the constraint set before re-evaluating; never proceed on a set that may have changed since the last load.
• Partial result: no partial permit is issued. An action is permitted only when every constraint is satisfied; otherwise it is refused or narrowed.
• Non-convergence: if no narrowing satisfies the constraints, the terminal result is refusal with the reason recorded. The refused action itself does not proceed or complete, so its own done predicate does not hold; this skill's done predicate holds because the refusal was recorded.

Output

For each evaluated boundary, a chat verdict (permit; narrow with the narrowed form stated; or refuse with the reason recorded), with the verdict sequence proving constraints were loaded before the first action, re-evaluated at every boundary, and an unreadable constraint set produced refusal rather than default-allow.
