Task: Integrate leadership dashboard product definition

Identity

Integrate feature commit 823d1cb6305077e1743f8783176d2cae3b5aec39 and its accepted leadership-dashboard product correction into canonical project memory.
Reconcile AUTH-001, architecture/data-flow, domain rules, current state, evidence, and reflection indexes.
Do not change runtime behavior, restart services, access ERP, mutate tasks, or send data externally.

Preserve the accepted three-role authorization and read-only manual-task dashboard boundary.
Record the user-confirmed distinction between an aggregate-first leadership operations view and an audit/debug history surface.
Canonicalize the rule that technical payloads and machine-shaped historical input are not rendered in the leadership dashboard while underlying audit evidence remains unchanged.

Accepted the feature task's promotion candidates without semantic conflict: the correction narrows presentation and product framing but does not widen access or change task mutation authority.
Updated AUTH-001, decision index, system overview, data flow, business rules, current state, evidence index, and reflection index.
Recorded feature commit 823d1cb6305077e1743f8783176d2cae3b5aec39 and this integration task under Integrated Through.
No runtime, database, ERP, external-system, or service-process state was changed.

Source feature verification: repository check 10/10, control-plane 153/153, legacy 256/256, TypeScript check/build, JavaScript syntax, focused 8/8, diff check, and authenticated browser drill-through all passed.

Create representative team-lead and ordinary-user accounts through the existing administrator workflow so the people-comparison dimension contains more than the migrated administrator.
Apply the control-plane projection on the next separately authorized service restart; the running static page already enforces the same leadership-safe presentation.
