T03: MCP alias retirement gate was unstartable — deprecation notices existed
but no mcp:* interfaces were ever registered or metered. Add
_meter_legacy_mcp() posting /legacy-meter/usage (kind mcp_tool, component
state-hub.mcp) from create_workstream, list_workstreams, update_workstream,
update_workstream_status, and state://workstreams/{topic_slug}; register all
five phase-3 backlog keys so zero-window streaks accrue from today.
T04: trace residual POST /progress/ workstream_id (3 calls/8h, unknown) to
.custodian-brief.md labelling workplans "workstream_id:"; brief generator now
prints "workplan_id:". Briefs refresh on each repo's next fix-consistency run.

Add retire_legacy_route() helper and convert CRUD, dependency, and
execution intent legacy routes to 410 Gone while preserving final-call
legacy-meter attribution. Update tests, retirement backlog, and close
STATE-WP-0075 with handoff to STATE-WP-0070 T02 and STATE-WP-0073 T04.
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.
Introduce flows/workplan.yaml and /flows/workplan/* routes alongside the
legacy workstream flow. Dashboard, README, and MCP flow docs now prefer
open_workplans with open_workstreams fallback until dual-key retirement.
Add the ranked legacy-interface backlog (T01), rename dashboard navigation and
user-facing copy to workplan while preserving wire-compat API keys (T02), and
activate the retirement workplan with T01/T02 marked done.
