+## Slice 25 - Business Overview Missing Proof Ledger
+
+This slice hardens the last high-risk semantic edge before the module can be treated as nearly closed: broad company analysis now carries a machine-readable ledger of the proof families that are still missing, instead of relying only on prose boundaries.
+
+The important distinction is not "can we say something useful?" because the current overview already can. The distinction is whether downstream answer drafting and future route expansion can reliably tell:
+
+- what was actually checked in the current turn;
+- what is only a bounded proxy;
+- what still has no reviewed route wired into runtime;
+- what must never be promoted into a confirmed business-audit conclusion.
+
+Implemented now:
+
+- `derived_business_overview.missing_proof_families` records the remaining hard proof families for accounting profit/margin, due-date debt aging, inventory reserve/liquidation quality, and vendor-risk/procurement quality;
+- each missing proof family exposes `current_status`, `current_supported_evidence`, `next_required_evidence`, and `must_not_claim`;
+- trading-margin evidence is explicitly recorded as `proxy_only_currently` for accounting profit/margin, not as clean profit or P&L;
+- open-settlement/debt-staleness evidence is explicitly recorded as proxy-only for due-date aging, not as contractual overdue debt;
+- inventory stock/turnover/staleness evidence is explicitly recorded as proxy-only for reserves, write-offs, obsolescence, and liquidation value;
+- supplier concentration is explicitly recorded as proxy-only for vendor/procurement quality, not as supplier reliability or full expense-structure proof;
+- the answer adapter adds a guard reason code and a `must_not_claim` rule so the proof ledger itself is not mistaken for an executed route.
+
+This is not a new exact P&L, payment-term, reserve/write-off, or vendor-risk engine. It is a semantic safety ledger for the remaining exact-route work: future slices can either wire a reviewed evidence route or keep the family honestly unproved.
+
+Local validation is accepted for this slice:
+
+- `npm.cmd test -- assistantMcpDiscoveryPilotExecutor.test.ts assistantMcpDiscoveryAnswerAdapter.test.ts`: passed `66` with `1` skipped.
