```markdown ## Executive Finding Current stock is answerable through the live API. Feature support is partial because A/B have documentary backing while C has taxonomy labels only. Model C warranty terms are unavailable. Purchase-history access is denied and must not be translated into "no purchases." Assumptions: the inventory API is the system of record for stock; the customer table denial applies to this session's role, not a permanent lockout. ## Answerability Matrix | Question family | Required evidence | Capable source/path | Status | Confidence | Basis | |---|---|---|---|---|---| | Feature support | Model-feature evidence | A/B manuals; taxonomy for C | PARTIAL | HIGH | Manuals back A/B; taxonomy cannot prove C support | | Current stock | SKU, quantity, timestamp | Inventory API | ANSWERABLE | HIGH | Direct executable source | | Model C warranty | Model-specific warranty text | None | UNAVAILABLE | HIGH | No warranty evidence path | | Purchase history | Authorized customer/order records | Denied customer table | UNAVAILABLE to caller | HIGH | Explicit access denial | ## Coverage Gaps | Gap | Failure mode | Impact | Smallest repair | Priority | |---|---|---|---|---| | No C manual | Taxonomy treated as evidence | Unsupported claims | Add versioned C manual | P0 | | No warranty corpus | Terms copied from A/B | Contract error | Add authoritative warranty source | P0 | | Denied customer view | Denial treated as empty | Privacy/false negative | Authorized purpose-bound view | P0 | ## Admission Rules Answer stock with timestamp; answer A/B feature claims with citations; answer cross-model questions partially; refuse purchase history; escalate Model C warranty. ## Unknowns Whether the customer-table denial is role-specific or account-wide is not established by the input.
