Repo Contract

The controller expects this layout in each bootstrapped repo:

.mosaic/orchestrator/
  config.json
  tasks.json
  state.json
  events.ndjson
  logs/
  results/

Quick Start

From a bootstrapped repo:

~/.config/mosaic/bin/mosaic-orchestrator-matrix-cycle
~/.config/mosaic/bin/mosaic-orchestrator-run --once
~/.config/mosaic/bin/mosaic-orchestrator-drain

Continuous loop:

~/.config/mosaic/bin/mosaic-orchestrator-run --poll-sec 10

Sync from docs/TASKS.md to queue:

~/.config/mosaic/bin/mosaic-orchestrator-sync-tasks --apply

Set worker command when needed:

export MOSAIC_WORKER_EXEC="codex -p"
# or
export MOSAIC_WORKER_EXEC="opencode -p"

Publish new orchestrator events to Matrix:

~/.config/mosaic/bin/mosaic-orchestrator-matrix-publish

Consume Matrix task messages into tasks.json:

~/.config/mosaic/bin/mosaic-orchestrator-matrix-consume

Matrix Note

This rail writes canonical events to .mosaic/orchestrator/events.ndjson. The Matrix transport bridge publishes those events into the configured control room and can consume task commands from that room.

Task injection message format (room text):

!mosaic-task {"id":"TASK-123","title":"Fix bug","command":"echo run","quality_gates":["pnpm lint"]}

MACP Notes

MACP-aware tasks add dispatch metadata on top of the existing queue model:

dispatch: exec, yolo, or acp
type: task category used for orchestration intent
worktree / branch: task-specific git execution context
brief_path: markdown brief consumed by runtime-backed dispatchers
result_path: structured result JSON written under .mosaic/orchestrator/

Controller behavior remains backward compatible:

Tasks without dispatch continue through the legacy shell execution path.
Tasks with dispatch use the MACP dispatcher and can emit task.gated and task.escalated.

Manual queue operations are exposed through:

mosaic macp submit ...
mosaic macp status
mosaic macp drain
mosaic macp history --task-id TASK-001
