The engine selects the algorithm per dimension from your plugin’s
schema(). You declare the shape — the engine handles identity,
diffing, and merge selection automatically.
One protocol. Any domain. Six methods between you and a complete version control system — branching, merging, conflict resolution, time-travel, and typed diffs — for free.
Every domain — music, genomics, 3D spatial, financial models — implements the same six-method protocol. The core engine handles everything else: content-addressed storage, DAG, branches, log, merge base, cherry-pick, revert, stash, tags.
The core engine provides four advanced capabilities that any domain plugin can opt into. Implement the protocol — the engine does the rest.
Unlike Git's blob diffs, Muse deltas are typed objects:
InsertOp, ReplaceOp, DeleteOp — each
carrying the address, before/after hashes, and affected dimensions.
Machine-readable with muse show --json.
{{TYPED_DELTA_EXAMPLE}}
Each plugin's schema() method declares its dimensions and merge mode.
The engine uses this to select the right diff algorithm per dimension and to
surface only the dimensions that actually conflict.
Plugins implementing StructuredMergePlugin get operational transformation. Operations at different addresses commute automatically — only operations on the same address with incompatible intent surface a conflict.
Plugins implementing CRDTPlugin get four battle-tested convergent data structures. No coordination required between replicas.
One command scaffolds the entire plugin skeleton. You fill in six methods. The full VCS follows.
raise NotImplementedError with your domain's
snapshot, diff, merge, drift, apply, and schema logic.
registry.py, then every Muse command works
for your domain out of the box.
muse domains --new genomics producesA fully typed, immediately runnable plugin skeleton. Every method has the correct signature. You replace the stubs — the protocol does the rest.

Domains currently registered in this Muse instance. The active domain
is the one used when you run muse commit, muse diff,
and all other commands.
Music is the reference implementation. These are the domains planned next — and the slot waiting for yours.
Three tiers of distribution — from local prototype to globally searchable registry. Start local, publish when ready.
A centralized, searchable registry for Muse domain plugins — think npm or crates.io, but for any multidimensional versioned state. One command to publish. One command to install.
