fork-fold maintenance repository

This repository is a fork-fold stack: an upstream base plus an ordered set of live topic branches, assembled into a single branch with tracked conflict resolutions.

• manifest.toml -- intent: remotes, base, ordered entries.
• manifest.lock.json -- fact: the OIDs and tree hash of the last build.
• resolutions/ -- tracked sidecar files replaying each conflicted merge.
• patches/ -- patch entries (escape hatch for cross-topic semantic fixes).

Common operations:

fork-fold add mine:some-branch   # append a topic
fork-fold build                  # assemble (incremental for appends)
fork-fold status                 # lock vs. manifest vs. live refs

The assembled branch is compiled output. Never develop on it, never merge it back into a topic.
