Summary

AI summary

Fixed path traversal, concurrent write loss, and non-atomic read‑modify‑write issues.

Full changelog

Patch release. Internal hardening, no API changes.

Fixed

  • Path traversal through excluded dirs: .git/.obsidian/.trash rejected at any depth, not just vault root.
  • Unconfigured-vault CWD leak: tools are no longer registered when no vault is configured (prevents path-traversal guards from resolving against process CWD).
  • Walker exposing nested excluded dirs: walkVault prunes excluded names at every depth.
  • Concurrent write loss: per-file locks extended to writeNote, deleteNote, moveNote. Lock keys case-normalized on Windows/macOS. moveNote sorts lock acquisition to prevent deadlock.
  • Non-atomic read-modify-write: new updateNote and updateCanvasFile helpers lock across the full read/transform/write. Used by update_frontmatter, add_canvas_node, add_canvas_edge.
  • TOCTOU in create paths: writeNote gained { exclusive } option using wx flag. create_note and create_daily_note use it.
  • writeCanvasFile unlocked: now takes the file lock.
  • Malformed YAML aborting vault-wide scans: parseFrontmatter returns empty data on parse failure instead of throwing. One broken note can't break get_tags/search_by_tag/search_by_frontmatter anymore.
  • Graph cache LRU evicting hot entries: buildLinkGraph refreshes recency on hit; capped at 32 entries.
  • Dead ensureNewline param removed from append_to_note schema (was declared but never wired).
