apply-stage-gate
Purpose
Apply explicit GO / HOLD / RECYCLE / KILL gates to a candidate or work package, tying each outcome to evidence thresholds and a next action.
Input contract
yamlrequired: [candidate_record, gate_criteria, evidence_register] optional: [prior_gate_decision, remediation_options] constraints: [each criterion has an observable status; gate outcome and next action are explicit]
Procedure
- Normalize the candidate, gate criteria, evidence, and unresolved assumptions into a gate table.
- Evaluate every criterion as met, unmet, or unknown, preserving the cited evidence and threshold direction.
- Apply precedence: KILL for disqualifying hard failure, RECYCLE for repairable failure, HOLD for insufficient evidence, otherwise GO.
- Emit the gate decision, failed criteria, evidence gaps, and the smallest justified next action.
Output contract
yamlproduces: [gate_table, gate_decision, failed_criteria, next_action] delta_fields: [findings, evidence_updates, uncertainties, decisions, recommended_jumps]
Quality gates
- A-class gate: declared universe = all candidate criteria and evidence items; numerator = criteria with explicit status and source; batch increment = one evaluated criterion; stopping reason = every criterion resolved or a hard failure terminates the gate; source references = criterion/evidence IDs; direction/threshold reason = GO requires all hard criteria met, while HOLD/RECYCLE/KILL follows the declared precedence.
- No GO is emitted while any hard criterion is unknown.
Failure and counterexamples
Do not turn an absent measurement into a pass. A repairable shortfall is RECYCLE only when a concrete remediation and re-gate condition are recorded.
