Authored entirely by Codex CLI (codex exec, reasoning effort high), one session
resumed across capacity fallbacks:
- gpt-6.1-sol (schema + initial db work, stopped at capacity)
- gpt-6-astra (db/server/agent/frontend, stopped at capacity)
- gpt-6-sol (remaining items, tests, fixes; stopped at capacity after final checks)
Schemes 1+2+3: prompt/acceptance (2..20, evidenced differences justify
independent, merged no longer blocked by unified report), group suggestions with
member table, superset reuse/subset superseded, veto-aware reject/exclusion,
anchor re-anchoring trigger, sweep after merge/reject/remove, frontend group card
with stale-response guard, candidate scoring with tier/hit_reasons/strong_total.
