# Deployment/API findings

1. `/api/lookup?polynomial=x%2Bmu` returned HTTP 500, while x+y succeeded.
   The local parser and the attempted draft fill identify the unsupported
   multi-letter token as the cause. The HTTP 500 is a site error rather than a
   mathematical rejection. Record a contributor-facing grammar lesson separately.
2. `POST /api/table/T558` with a complete prose document and empty Numbers was
   rejected with "A table needs at least one entry ... Send X-Draft: yes ...".
   The endpoint calls `_document_of(request)` without allowing an empty draft;
   its suggestion does not match that endpoint's behavior. No edit resulted.
3. Authenticated API reads can access the draft while browser page URLs return
   404 with only a Bearer API header. No browser session was established.

No source changes or deployment were attempted. These findings are artifacts
under the artifact-run policy, not edits to docs/agent-environment.md.
