CHANGELOG.md

@@ -24,7 +24,7 @@ The format is inspired by Keep a Changelog, and version tags follow the reposito
 - Unit tests now cover chat-completions parsing and knowledge-card note generation
 - Coding-plan analysis now defaults to `glm-4.7`, instead of probing `glm-5` first
 - BigModel / z.ai `chat/completions` summary requests now disable `thinking` by default so `glm-4.7` returns final answer text instead of reasoning-only payloads
-- GitHub cards now use the exact repository name as the note title, student-learning sections, repository-specific summaries, method checkpoints, branch tags, and category links instead of generic web-page sentence ranking
+- GitHub cards now use the exact repository name as the note title, plus a DeepWiki-inspired breakdown: what problem the repo solves, how the system is layered, which paths to read first, and how to start digging into the code
 - Knowledge-card notes no longer dump full raw content for high-confidence web / GitHub captures; folded evidence is only shown for lower-confidence fallback cases or transcript-style media
 - Obsidian knowledge indexes now insert new cards under the correct date heading instead of appending entries into the wrong day block
 - Obsidian `_log.md` now uses the same date-grouped one-line entry style as `_index.md`, so historical notes and new ingest logs stay readable
