Research sweep captured in research/20260709-workstream-caller-sweep.md.
Migrate dashboard detail tasks query, custodian_cli POST bodies, and
onboarding curl to workplan-first paths; re-capture 8h legacy-meter evidence.
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.
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.
