Verify quality gates between work groups

Verify single-task group independently before advancing

Enforcing independent evidence per task before multiplying work; prevents bad specs from cascading into later phases.

• · task group (Group A/B/C...)
• · verification command
• · Iron Law evidence (test pass, screenshot, assertion)

• · checkpoint pass/fail verdict
• · verification evidence logged

• · verification command (test, lint, build)
• · conducty-verify

Task group executed; verification criteria pre-specified in plan

• · self-attested 'done' without independent evidence → advances bad code
• · verification command flaky → false positives/negatives

• · Iron Law: no advancement without independent evidence
• · Tracer-first pattern (one task per group before parallelizing)
