North-star acceptance + plan-agnostic + SSOT proof

Goal

Seeded contradiction fixtures turn verify_roadmap --full red; the north-star acceptance proves —full green across the corpus AND all six gates consume the one engine; the tooling stays plan-agnostic.

Implementation Sketch

Author the acceptance suite: an R2 seeded contradiction and an R3 seeded mission_violation each flip —full to exit 2; the green-corpus acceptance asserts —full green + each of the six gates calls assess (no parallel detector). A plan-agnostic test asserts no plan-name/domain hardcode (script-first.md §11). An SSOT test greps that assess is the only evaluator.

Work Items

• Seeded R2 contradiction fixture: two active plans where A removes what B relies on -> verify_roadmap —full exits 2
• Seeded R3 mission_violation fixture: A’s success criterion falsifies B’s mission gate -> —full exits 2
• North-star acceptance: —full green on a coherent corpus AND each of the six gates demonstrably consumes assess (the functional mission probe)
• Plan-agnostic generic-tooling test: no plan-name/domain hardcode in corpus_alignment or verify_roadmap —full (script-first.md §11)
• SSOT test: assert assess is the single alignment evaluator (no parallel detector); LEAK:algorithmic-duplication guard
