 `epiphany-pipeline/src/lib.rs` and the four schema files, this cut is wrong**:
 stop and report rather than retyping.
 
+**Landed 2026-09-16** at `4d6af409` (deletes; does not build by design, the
+outcome having no `Bounded` impl until the next commit), `13570e84` (the

+`tools/eureka-cut6c-mutations.psd1`). Hands re-anchored by content, since
+`lib.rs` had moved twice since `95ee551a`; the spec's "twenty tests" was
+twenty-one by then. `schemars` 1.2.2 accepted the `extend` attribute on the
+variant field, and `"maxItems": 8` appears exactly once, under
+`Superseded.by`. Six schema files regenerated (+193/−22); `index.json`

+Corrections and scars from Hands:
+
+29. **M19 and M20 first came back "DID NOT BUILD."** The sample and the test
+    spelled the label and commit with the newtype constructors, so widening
+    the type made the tree fail to compile instead of admitting the forgery.
+    Fixed by constructing through `From<&str>`. A type-level mutation only
+    reads as a kill when the fixture is spelled so the widened tree compiles;
+    the spec implied that and did not say it.
+30. **`5f98228` is a legal seven-character sha**, so it was no forgery;
+    replaced by six characters.
+31. **The estimate test carries one assertion beyond the spec**: the sample
+    estimate equals the sample report's structural delta, which required
+    aligning the sample's `formats_added`. Soul is asked whether that moved
+    anything else.
+32. **The refusal `value` is the failing part, not the whole id**, so the
+    third-batch reader fixture asserts `field` only, as Cut 6b's did.

+Soul in flight.
