patch.moi

Git-first maintenance control plane for custom patches on top of upstream open source software.

Canonical public host: https://patch.moi.

Repository

This is a Bun monorepo:

• apps/patch: the Patch service, feed poller, JSONL store, Discord output, and workspace backend adapter.
• docs: Tome documentation site for patch.moi.

patch.moi treats Git as the source of truth for maintained projects. Upstream and fork remotes, patch branches, tags, and commits describe the patch stack. Patch records update intake, dispatch attempts, and operational history around those Git facts.

Environment

HOST=0.0.0.0
PORT=3000
DATA_DIR=./data
DISCORD_OUTPUT_ENABLED=false
DISCORD_WEBHOOK_URL=
DISCORD_NOTIFY_EVENTS=push,release
FEED_SOURCES_PATH=./feed-sources.json

Discord notifications are off by default. Set DISCORD_OUTPUT_ENABLED=true and DISCORD_WEBHOOK_URL to send Discord output. DISCORD_NOTIFY_EVENTS is a comma-separated allow list and defaults to push,release.

Development

bun install
bun run check
bun run workspace:doctor
bun run dev

Feed watcher events are configured in apps/patch/feed-sources.json. The first poll primes DATA_DIR/feed-state.json; later polls append upstream activity to DATA_DIR/feed-events.jsonl. Targets using mode: "fork_sync" append legacy work to DATA_DIR/feed-jobs.jsonl. Targets using mode: "workspace_flow" append generic flow events to DATA_DIR/flow-events.jsonl, send them to the configured workspace backend or local adapter, and record dispatch outcomes in DATA_DIR/workspace-dispatches.jsonl. Each dispatch also creates or updates a patch.moi-owned DATA_DIR/maintenance-attempts.jsonl entry that links the upstream update to workspace run ids, final flow outcome, and candidate refs.

Patch can dispatch through a configured workspace backend, through the codex-flows Actions/local surface with CODEX_WORKSPACE_MODE=actions, or through synchronous local flow execution for development. The backend does not need to be running in this checkout unless you are explicitly testing or operating that surface.

The harness can also be run through the repo-native workspace task:

CODEX_FLOW_FETCH=0 CODEX_FLOW_PUSH=0 bun run workspace:run:harness

That task writes local operator run state under .codex/workspace/local/, which is ignored by Git. Patch service state remains under DATA_DIR.

Documentation

The publishable docs site is a Tome project in docs/:

bun run docs:dev
bun run docs:build

Docs source follows the Diataxis framework under docs/pages/tutorials, docs/pages/guides, docs/pages/reference, and docs/pages/concepts.
