From fb4b1e3c58f65c2ad609c7e4132282cbc5991ca0 Mon Sep 17 00:00:00 2001 From: weichen Date: Wed, 14 Oct 2026 02:51:30 +0000 Subject: [PATCH] Gate material choices on verified results MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Why: failed or ungrounded material notices still asked nontechnical users to choose deliverables and could act on invented model options. Evidence: failure, partial, no-suggestion, forged-marker, source-drift, reload and host-option RED→GREEN tests; race, isolated PostgreSQL, full Backend vet and tests pass. Impact: only a completed source-bound result with 3-4 bounded suggestions can offer a choice; failed or stale notices preserve truthful status and block unsolicited delegation.
