Stop dual-publishing org.statehub.workstream.completed; return 410 Gone for
legacy DELETE /workstreams/{id}. Migrate fix-consistency, MCP adhoc bootstrap,
and dashboard token summary to /workplans/. Add legacy-meter evidence capture
script and pytest snapshot; update docs and close out the workplan.
Share LegacyWorkstreamIdBodyMixin across create schemas; meter POST /tasks/
and /decisions/ workstream_id bodies. State summary uses workplan flow;
NextStep dual-writes workplan_* fields alongside legacy workstream_*.
Add Sunset to legacy compat responses (Jun 2027 planning horizon).
Meter POST /progress/ bodies that use workstream_id; wire hub-core body
hook. Consolidate workstreams deprecation headers via legacy_compat.
Wire hub-core progress legacy-meter hook for GET /progress/?workstream_id.
MCP list_tasks, list_blocked_tasks, and list_human_interventions now call
REST with workplan_id only so internal clients do not inflate legacy usage.
Add legacy_compat helper and Deprecation headers when callers filter
/tasks, /decisions, /token-events, or /execution/launch-requests with
workstream_id. Preferred workplan_id filters are unchanged. Route removal
remains gated on legacy-meter zero-usage windows.
Adds preferred workplan REST/event surfaces, legacy-meter telemetry and weekly review summaries, documentation/dashboard terminology updates, dashboard API loading fixes, and close-out sync for STATE-WP-0052 and STATE-WP-0054.
