1. Seed key-coverage gap: build.sh:2405 only seeded 3 of 6 provider keys.
ZAI_API_KEY, ANTHROPIC_API_KEY, and EMBED_API_KEY were defined in
build.cfg and written to the manifest but never reached the seed
partition. Expanded grep pattern to all 6.
2. AGENTS.md test header: marked PENDING/xfail with a stale comment
referencing a not-yet-merged patch. The importer has shipped this
feature (clawdie-live-seed lines 361-369). Updated comment and
section header to reflect shipped status.
