millrace-ai 0.11.1

Millrace runtime rewrite baseline package

Millrace

Millrace is a thin-core autonomous runtime packaged as millrace_ai.

The runtime bootstraps all operational files under <workspace>/millrace-agents/ and keeps canonical source code in the package itself.

Source Layout

• importable code lives under src/millrace_ai/
• tests mirror package ownership under tests/assets/, tests/cli/, tests/config/, tests/runners/, tests/runtime/, tests/workspace/, and tests/integration/
• preserved compatibility facades remain at the package root for legacy imports such as millrace_ai.control, millrace_ai.run_inspection, millrace_ai.runner, millrace_ai.entrypoints, and workspace support modules

Use docs/source-package-map.md for the old-to-new module map and the intentionally preserved facade list.

Quick Start

WORKSPACE=/absolute/path/to/workspace

uv run --extra dev python -m millrace_ai compile validate --workspace "$WORKSPACE"
uv run --extra dev python -m millrace_ai run once --workspace "$WORKSPACE"
uv run --extra dev python -m millrace_ai status --workspace "$WORKSPACE"

Equivalent installed CLI:

millrace compile validate --workspace "$WORKSPACE"
millrace run once --workspace "$WORKSPACE"
millrace status --workspace "$WORKSPACE"

Operator Surface

Use the shortest truthful forms for routine operation:

• millrace run once
• millrace status
• millrace runs ls
• millrace queue add-task <path-to-task.md|path-to-task.json>
• millrace pause, millrace resume, millrace stop

millrace status show remains available as the explicit subcommand form, but the canonical operator example is millrace status.

Use docs/OPERATOR_GUIDE.md for the current operator workflow and docs/runtime/millrace-cli-reference.md for the full command inventory, grouped forms, and alias details.

Work Artifacts

Canonical queue artifacts are lightweight headed markdown work documents (.md) under:

• millrace-agents/tasks/{queue,active,done,blocked}/
• millrace-agents/specs/{queue,active,done,blocked}/
• millrace-agents/incidents/{incoming,active,resolved,blocked}/

Task/spec/incident files use a human-facing shape with an H1 title plus plain field headings such as:

# Add run inspection CLI

Task-ID: example-task-001
Title: Add run inspection CLI

Target-Paths:
- src/millrace_ai/cli/commands/runs.py

Acceptance:
- `millrace runs ls` reports persisted run summaries.

JSON remains runtime-internal for snapshot, diagnostics, mailbox archives, and event/log surfaces.

Stage Runner Resolution

Runtime stage execution now routes through a configurable runner dispatcher.

Resolution order per stage request:

1. request.runner_name (compiled from mode/stage bindings)
2. runners.default_runner from runtime config
3. fallback literal codex_cli

Default adapter is Codex CLI. Add runner settings in <workspace>/millrace-agents/millrace.toml:

[runners]
default_runner = "codex_cli"

[runners.codex]
command = "codex"
args = ["exec"]
permission_default = "basic"
# permission_by_stage = { builder = "elevated" }
# permission_by_model = { "gpt-5.4" = "maximum" }
skip_git_repo_check = true

Permission levels map to Codex CLI flags:

• basic: --full-auto
• elevated: -c approval_policy="never" --sandbox danger-full-access
• maximum: --dangerously-bypass-approvals-and-sandbox

Verification

Authoritative local verification commands:

uv run --extra dev python -m pytest -q
uv run --with ruff ruff check src/millrace_ai tests
uv run --with mypy mypy src/millrace_ai

Operational source + wheel checks (minimum functionality workspace):

WORKSPACE=/absolute/path/to/minimum-functionality-workspace

rm -rf "$WORKSPACE/millrace-agents"

uv run --extra dev python -m millrace_ai compile validate --workspace "$WORKSPACE"
uv run --extra dev python -m millrace_ai run once --workspace "$WORKSPACE"
uv run --extra dev python -m millrace_ai status --workspace "$WORKSPACE"

rm -rf "$WORKSPACE/millrace-agents"

uv build --wheel
python3 -m venv /tmp/millrace-wheel-test
source /tmp/millrace-wheel-test/bin/activate
pip install dist/*.whl
millrace compile validate --workspace "$WORKSPACE"
millrace run once --workspace "$WORKSPACE"
millrace status --workspace "$WORKSPACE"

For clean proof runs, refresh only "$WORKSPACE/millrace-agents/" in place. Do not mutate operator-authored files elsewhere in the workspace root.
