Auto-edge Implementation: Design Analysis Findings and Fixes

Issues Found and Fixed

1. Similarity threshold bypass — keyword-only results lack a "similarity" key, so if similarity is not None always short-circuited the threshold check. Fixed by requiring tag overlap for the keyword-only path instead.

2. Backwards description arrow — The → in the edge description could point the wrong direction when a heuristic reversed from/to. Fixed by building the description string after direction resolution.

3. Wasted slice slots — [:AUTO_EDGE_MAX] slice happened before threshold filtering, consuming slots on results that would later be rejected. Fixed by filter-then-slice ordering.

4. Weak recall query — Title-only recall gave weak signal. Fixed by concatenating tags into the query string.

Deferred Issues (Not Fixed This Session)

• Git commit batching in relate() (issue #2)
• Semantic recall surfacing dormant memories (issue #3)
