Origin session history

This branch is written automatically by Origin. It is not part of your codebase — nothing here is built, imported, or deployed. It records which AI agent wrote the code on the other branches, and the prompt behind each change.

You don't need Origin installed to read any of it. Plain git is enough.

Layout

sessions/<session-id>/metadata.json   model, cost, tokens, duration, commits
sessions/<session-id>/prompts.md      the prompts, in order
sessions/<session-id>/changes.json    per-prompt diffs and files touched

Reading it

List the sessions:

git ls-tree --name-only origin/origin-sessions:sessions/

Read the prompts behind one:

git show origin/origin-sessions:sessions/<session-id>/prompts.md

Per-commit attribution (one extra step)

Origin also writes a git note per commit, so git log can show you which agent wrote it and why. Notes live in refs/notes/origin, and git clone does not fetch them — that's a git default, not an Origin choice. Bring them down once:

git fetch origin refs/notes/origin:refs/notes/origin

Then, with plain git:

git log --show-notes=origin

To keep them arriving on every ordinary git pull, add the refspec:

git config --add remote.origin.fetch '+refs/notes/origin:refs/notes/origin-remote'

(That stages them into refs/notes/origin-remote. Origin merges the staging ref into refs/notes/origin so your own local notes are never overwritten — mapping the remote straight onto refs/notes/origin with a forced refspec would silently destroy any note you hadn't pushed yet.)
