+## 0.8.13 (2026-05-18)
+
+- Fix: node ID collisions across same-named files in different directories — SQL extractor and Python import resolver now use directory-qualified stems (`dir_file_entity`) instead of bare filename stems, preventing silent node merging on repos with duplicate filenames (#1A, #1B)
+- Perf: stat-based mtime fastpath for `file_hash` — skips full SHA256 read when file size+mtime_ns unchanged, same trade-off as make; index flushed atomically via atexit
+- Fix: absolute `source_file` paths from semantic subagents no longer stored in graph — `build_from_json`, `build`, and `build_merge` accept a `root` param and relativize paths at build time (#932)
+- Fix: failed semantic chunks no longer permanently freeze their files in the manifest — only files that appear in extraction output get `semantic_hash` stamped; failed-chunk files keep empty `semantic_hash` and are re-queued on next run (#933)
+- Feat: `graphify cache-check`, `graphify merge-chunks`, `graphify merge-semantic` CLI subcommands expose cache and merge logic as library-callable commands for skill pipelines
+
 ## 0.8.12 (2026-05-18)
 
 - Security: `_is_sensitive` now correctly flags underscore-prefixed secret filenames (`api_token.txt`, `oauth_token.json`) — `\b` word boundary was treating `_` as a word char, so names like `api_token` never matched (#920)
