I use Graphify a lot, and one thing I wanted to explore further was time — when did a node first show up, what came before what. Graphify already gives you the structure; I wanted to add a temporal layer on top of it.

Turns out your filesystem already tracks this: mtime, ctime, birthtime, even the parent directory's mtime. That's a timeline sitting there for free, no LLM call needed.

So I built graphify-temporal, a companion CLI that runs after a graphify build:

graphify-temporal enrich --cross-file --use-birthtime

It stats the file behind each node, stamps file_mtime / file_birthtime / dir_mtime, and chains nodes with preceded_by edges — within a file by line order, and optionally across the whole project. It's idempotent, so you can re-run with different flags anytime.

Once the graph has timestamps, query and timeline let you filter and walk it by time — what changed since a date, oldest node in a file, gap stats across the project.
