+ * v1.30.25 — prompt injection arriving through a DATA field.
+ *
+ * The pre-existing red-team battery probes hostile USER MESSAGES and hostile
+ * MODEL REPLIES. Neither covers the channel that actually reaches the prompt
+ * without passing a guard: a lab analyte / panel / unit name, or a medication
+ * label. Those strings are not authored by the user. A lab row committed from
+ * an uploaded document carries the name a model transcribed out of that PDF,
+ * stored verbatim as `Biomarker.name` by `resolveOrMintBiomarker`, and from
+ * there it lands in the Coach SNAPSHOT and in the `labs_read` tool result on
+ * every turn. The document, not the account holder, chooses the string.
+ *
+ * These cases drive the REAL chain — `buildLabsSnapshotBlock` over a mocked
+ * Prisma, then the real fencing helpers — and assert the two guards that
+ * apply: the field sanitiser at the data source, and the fence around the
+ * block. The model's contract must be unreachable from a data field.
