v0.2.3 — Auto-Update

🚀 v0.2.3 — Auto-Update + Simplify-Review Fixes

New MCP Tools (2)

• check_update 🔄 — Check if a newer version is available
• do_update ⬆️ — Pull latest from GitHub, reinstall, self-restart

Simplify-Review Fixes (9 Issues)

1. Event-Loop Blockade — _check_for_update + _do_update von sync auf async+run_in_executor umgestellt
2. User-Agent hardcodiert — "nexus-memory/0.2.0" → f"nexus-memory/{nexus_version}"
3. Version-Cache Bug — nach pip install aus Datei gelesen via importlib.reload statt from nexus import (sys.modules Bug)
4. Repo-Pfad hardcodiert — ~/nexus-memory → dynamisch aus nexus.file abgeleitet
5. git fetch redundant — entfernt (git pull --ff-only macht fetch selbst)
6. os._exit(0) unsauber — stdout.flush() vor Exit
7. Version-Vergleich — split/int → packaging.version.parse (robust gegen Suffixe)
8. Duplicate Handler — veralteter sync do_update Block gelöscht
9. setup.sh (2 Fixes) — macOS grep -oP → -oE; uv --system in venv gefixt

Self-Restart

After a successful update the server exits cleanly. The MCP client restarts it automatically.

v0.2.2 — Justification Check (Rung 2)

Justification Check (Rung 2) — Source URL Verification on Recall.

New Feature

• verification field in recall results — each result now includes:
  • verified — source URL is reachable
  • unreachable — source URL unreachable or blocks HEAD requests
  • unchecked — no source_url was set
• Payload enrichment — hybrid results now carry full provenance (source_url, access_level, category, source)
• Parallel async HTTP HEAD checks on all source URLs at recall time

Docs

• AGENTS.md: Justification Check section added

Follows Rung 2 (Justification Verification) from Spivakovsky's Ladder of Checks.
