Why: branch protection requires the head to contain the current base before merge.
Evidence: fetched origin/main=336a90f0ade0ffe049879ca5159a61f0a3948708.
Impact: integrate upstream changes without rewriting task history.
Refs: Documents PR #63
Why: the user reviewed and approved the plan (2026-10-11, five stages bundled) and chose a two-tier admin model for KTD4 instead of strict ledger separation.
Evidence: SELF user session rulings recorded in the Dev task card; document-check receipt follows in the task card evidence section.
Impact: proposal r1 and INDEX now record approval and the two-tier admin ruling; no code or deployment change.

Why: assess existing two-tree and trace-network capabilities and define project-scoped inspection.
Evidence: SELF source receipt and document checks; business and runtime verification were not run.
Impact: pending-review proposal and index only; no product implementation or deployment.
