-# Phase 1 (semantic) of the Knowledge Genome ingest — the LIGHT version.
+# Phase 1 (semantic) of the Knowledge Genome ingest — light agent + deterministic conform.
+#
+# - FIXED: Add 'title:' field to frontmatter (lint was complaining about missing title)
+# - NEW: Inject existing index (entity/concept names) into prompt to prevent duplicates
+# - NEW: Richer prompt asking for 2-4 sentences per description (not 1-2), with concrete details
+# - Enhanced schema to handle longer descriptions naturally
 #
 # The model does ONLY semantic extraction and returns ONE schema-constrained JSON
 # object (no tools, no file writing, no git, no frontmatter, no slugs). This script
 # then CONFORMS that output deterministically into wiki pages with enforced
 # frontmatter + kebab-case paths, and writes a .ingest-manifest.json in EXACTLY the
-# schema run-ingest.sh expects. run-ingest.sh (phase 2) then does index / log /
-# scoped-lint / PR, unchanged.
+# schema run-ingest.sh expects.

-# Why this shape: local tool-calling via pi/ollama proved fragile, and a small
-# model does not reliably honour folders / naming / frontmatter / manifest schema
-# when it writes files itself. Here the model cannot break the contract because it
-# never touches the filesystem — the script owns all structure. Stdlib only.
-#
 # Emits a single JSON status line on stdout (for n8n / logs).
