From b270aa5624b84ae5cf6031d299554dcf5f45d61c Mon Sep 17 00:00:00 2001 From: robbond Date: Mon, 31 Aug 2026 09:22:50 +0100 Subject: [PATCH] =?UTF-8?q?feat(confidence-engine):=20case/update=20synthe?= =?UTF-8?q?sis=20=E2=80=94=20dedicated=20reconstruction=20per=20update=20(?= =?UTF-8?q?v0.50)?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Architecture: after successful /api/cases/update, derive explicit nextGraph + nextFindings, call synthesizeFromFindings exactly once, replace Current Understanding with reconstruction result. Key invariants: - outcome.summary retired as final CU authority → always synthesis reconstruction - Explicit derived state (no React-state reread) for graph and findings - Previous CU preserved on synthesis failure (no fallback to outcome.summary) - Graph and Findings NOT lost on synthesis failure - saveInvestigation persistence uses currentUnderstanding, not outcome.summary Deterministic regression: 7 tests (Cases A-E + 2 edges) covering all rules.
