Three conde clauses: empty list -> empty result; head matches x ->
skip and recurse; head differs (nafc-gated) -> keep and recurse.
Distinct from rembero, which removes only the first occurrence.

- **2026-05-08** — **removeo-allo**: removes every occurrence of x (vs rembero, which removes only the first). Three conde clauses: empty -> empty; head matches -> skip and recurse; head differs (nafc) -> keep and recurse. 5 new tests, 446/446 cumulative.
- **2026-05-08** — **btree-walko (matche showcase)**: walks a binary tree (:leaf v) | (:node l r) and emits each leaf value via conde. Demonstrates matche dispatch on tagged-list patterns, recursion through both branches via conde, and run* enumerating all 5 leaves of a small tree. 4 new tests, 441/441 cumulative.
- **2026-05-08** — **swap-firsto**: swap the first two elements of a list. Built via four conso constraints. Self-inverse on length-2+ lists; runs forward and backward. 6 new tests, 437/437 cumulative.
- **2026-05-08** — **pairlisto**: relational zip — pairs is the zipped list of (l1[i] l2[i]). Runs forward, recovers l1 given l2 and pairs, recovers l2 given l1 and pairs. 5 new tests, 431/431 cumulative.
