P1–P3 shipped libraries but kb-app facade is still all `bail!("not yet
wired")` stubs, so the CLI is structurally complete but unusable.
Insert p3-5 between P3-4 and P4-1 to swap the facade bodies — ingest,
search, list_docs, inspect_doc, inspect_chunk — into real
compositions of the libraries shipped through P3-4. `ask` stays
stubbed; P4-3 owns it.
After p3-5 merges:
- `kb index` walks a workspace and persists chunks (SQLite +
optionally LanceDB).
- `kb search --mode {lexical,vector,hybrid}` returns real SearchHits
with citations.
- `kb list` / `kb inspect doc|chunk` round-trip from the store.
Updates:
- New task spec at tasks/p3/p3-5-app-wiring.md (depends_on
p1-6/p2-2/p3-2/p3-3/p3-4; unblocks p4-3/p9-1/p9-2/p9-4).
- tasks/INDEX.md bumps P3 component count 4 → 5 and adds the link.
- tasks/phase-3-vector-hybrid.md replaces the speculative
`embed_index` facade signature with the actual frozen kb-app
surface and updates the phase completion checklist.
