_ground_feedback_corpus now pulls matched email bodies (the richest objection
signal) alongside communications and grid notes, round-robin merged so email is
never crowded out by a flat LIMIT, per-item capped at 4000 chars to keep the local
minimize tractable on long threads, and degrading gracefully when the email tables
are absent. Email remains Tier-2-sensitive: it only ever enters the redaction
boundary, never Claude directly. Inert until Gmail capture is enrolled. Not yet
deployed (bundles into the next release with the meeting-notes work).
Test: test_ground_corpus.py.
