From 9cd680051f201d362f87104b4c66d26bb8ae9fac Mon Sep 17 00:00:00 2001 From: Number531 <120485065+Number531@users.noreply.github.com> Date: Sun, 17 May 2026 00:16:45 -0400 Subject: [PATCH] =?UTF-8?q?feat(kg):=20v6.12.0=20=E2=80=94=20deterministic?= =?UTF-8?q?=20entities.json=20synthesis=20for=20legacy=20backfill?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Transparent 4-tier deterministic synthesizer inside /api/admin/sessions/:key/ rebuild-kg. When entities.json is absent from report_artifacts, synthesizes from data already structured in the DB before running the existing 10-phase KG build. Zero LLM, zero new endpoints, zero frontend changes, zero schema. Tiers (all fail-soft, skip rather than misclassify): 1. Parse ## DEAL_METADATA from orchestrator-state markdown 2. Static map: research agent report_keys → regulator catalog 3. Union with kg_nodes WHERE node_type='regulator' (session-specific) 4. Mine fact_node.fact_name for narrow entity-keyword patterns Dedup case-insensitive on canonical_name; higher-tier wins, loser's match_patterns merge into winner. 50-cap enforced at synthesis + Zod. Operator UX unchanged — existing "Rebuild KG" button gains capability: legacy sessions get entities_source: "synthesized" + per-tier audit; fresh v6.11.0+ sessions continue entities_source: "native". Failure of synthesis is logged but never blocks rebuild — LEGACY fallback still kicks in. Expected SpaceX backfill yield: ~15-18 entities. Phase 9 recovery target: 267 → ~1,500 edges.
