- resolved 9g's forks EMPIRICALLY against the running compiler:
- count(<query>) and len(<query>) already work (fork 2 collapses to
zero code)
- skillhost's correlated NOT EXISTS is a backlink emptiness in
writeonce (`where len(x.children) == 0`), using only 9b machinery
(fork 1) — verified on a self-referential ?ref/backlink table
=> corpus #1 forces NO new grammar; per the method ("add only what a
corpus uses"), exists/not-exists was NOT built
- docs/examples/skill-catalog: mirrors skillhost's `skills` table
(name @unique, description/location/root, parent ?ref Skill, children
backlink) and translates all five of its SQL statements 1:1
(insert+dup-trap, get-by-name, list, roots via backlink-emptiness,
count); scripts/skill-catalog-accept.sh 7/0, WAL-durable, dup trap
persists across restart
- fixture run/db-query-corpus (count(query) + backlink NOT EXISTS);
just skill-catalog module; target/ gitignored
- general exists/not-exists left unbuilt and recorded as "enters when a
corpus forces a non-relation correlation"
- gates: oop-e2e 80/0, woc-test 566/0, skill-catalog 7/0; story + board
record the finding
