New achievements table: stage_completed/curriculum_completed/assessment_completed/ capstone_completed, idempotent (WHERE NOT EXISTS guard, not a unique-index dance — simple and correct at this write volume). Not a certificate — a durable internal record Phase 4/5 can render one from later. recordAssessmentAchievement only fires on an actual pass, defensively, even though today's only completion_rule already guarantees that.

-- Persistent completion records — stage/curriculum/assessment/capstone. Not a certificate
|
|
-- (Phase 4/5 territory, see docs/PHASE3B_LEARNING_AND_ASSESSMENT.md): just the durable fact
|
|
-- that something was achieved, with enough context to render a certificate from later without
|
|
-- re-deriving it from raw attempt history.
