What

Adds shortest_path() and path_explanation() to MnemosyneArchive.

BFS-based pathfinding through the connection graph answers "how is memory X related to memory Y?" by finding the shortest chain of connections.

Changes

archive.py: shortest_path(start_id, end_id) and path_explanation(path) methods
cli.py: mnemosyne path <start_id> <end_id> command
tests/test_path.py: 8 test cases covering direct, multi-hop, no-path, same-entry, nonexistent, shortest-of-multiple, explanation, and truncation
FEATURES.yaml: marked memory_pulse as shipped, added memory_path

Example

$ mnemosyne path abc123 def456
Path (3 hops):
   abc123: The Architecture of Meaning
     topics: philosophy, structure
   → xyz789: Semantic Networks in Cognition
     topics: cognition, graphs
   → def456: Memory as Graph
     topics: memory, holographic

## What Adds `shortest_path()` and `path_explanation()` to `MnemosyneArchive`. BFS-based pathfinding through the connection graph answers "how is memory X related to memory Y?" by finding the shortest chain of connections. ### Changes - `archive.py`: `shortest_path(start_id, end_id)` and `path_explanation(path)` methods - `cli.py`: `mnemosyne path <start_id> <end_id>` command - `tests/test_path.py`: 8 test cases covering direct, multi-hop, no-path, same-entry, nonexistent, shortest-of-multiple, explanation, and truncation - `FEATURES.yaml`: marked `memory_pulse` as shipped, added `memory_path` ### Example ``` $ mnemosyne path abc123 def456 Path (3 hops): abc123: The Architecture of Meaning topics: philosophy, structure → xyz789: Semantic Networks in Cognition topics: cognition, graphs → def456: Memory as Graph topics: memory, holographic ```
