Phase 2 moves the dashboard off raw task-state leakage and onto stable public projections. Task status, task listings, progress websocket events, and portfolio recommendation reads now load persisted contracts when available, expose a contract-first envelope, and keep legacy fields inside a compat block instead of smearing them across top-level payloads.
Constraint: existing task-status JSON and recommendation files must continue to read successfully during migration
Rejected: return raw task_results directly from API and websocket | keeps legacy fields as the public contract and blocks cutover
Rejected: rewrite stored recommendation files in-place | adds risky migration work before rollout gates exist
Confidence: high
Scope-risk: moderate
Reversibility: clean
Directive: keep public payload shaping in job/result-store projections, not in ad-hoc route logic
