tigrbl-runtime

Runtime pipeline helpers and execution bridge surfaces for Tigrbl ASGI applications, transports, and operation dispatch.

What is tigrbl-runtime?

Runtime pipeline helpers and execution bridge surfaces for Tigrbl ASGI applications, transports, and operation dispatch.

Why use tigrbl-runtime?

Use it when you need this foundational Tigrbl layer directly as a small, focused dependency.

When should I install tigrbl-runtime?

Install it for extension packages, package-local tests, or internals that need this boundary without the whole facade.

Who is tigrbl-runtime for?

Framework maintainers, extension authors, and advanced users composing Tigrbl from split packages.

Where does tigrbl-runtime fit?

tigrbl-runtime lives at pkgs/core/tigrbl_runtime and serves a focused layer in the split Tigrbl framework.

How does tigrbl-runtime work?

It owns a narrow layer in the split workspace and is consumed by higher-level packages through explicit dependencies.

Certification Status

• Package status: governed package in the tigrbl/tigrbl workspace.
• Governance source: SSOT registry.
• Release evidence: publish workflow validates package builds, tests, GitHub release assets, and PyPI publication for managed packages.
• Local certification guard: pkgs/core/tigrbl_tests/tests/unit/test_package_badges_and_notices.py verifies every package README keeps the Discord badge, Apache 2.0 badge, explicit Python-version badge, LICENSE, and NOTICE.
• Scope note: this README documents the package boundary. Runtime feature support remains governed by .ssot/ entities and the conformance docs linked below.

What It Owns

tigrbl-runtime owns the foundational framework package boundary. It should be installed when you need this package's focused responsibility without assuming every other Tigrbl workspace package is present.

Implementation orientation:

• tigrbl_runtime: callbacks, channel/, config/, executors/, protocol/, runtime/, transactions, webhooks

Runtime authoring BCP:

• Do use this package for runtime-owned routing, request execution, transport-unit execution, framing atoms, transport channels, transaction helpers, and kernel integration.
• Do keep handler invocation, transaction progression, error handling, and transport emission aligned with compiled plans.
• Do not make application route handlers, FastAPI/Starlette objects, direct SQLAlchemy session calls, or ad-hoc engine construction the runtime contract.
• Do not bypass kernel plans or lifecycle phases when adding REST, JSON-RPC, stream, SSE, WebSocket, or WebTransport behavior.
• Avoid hiding behavior in transport wrappers that diagnostics and compiled plans cannot inspect.

Public API and Import Surface

• Import roots: tigrbl_runtime.
• Public symbols: Runtime, RuntimeBase.
• Workspace dependencies: tigrbl-typing, tigrbl-kernel, tigrbl-atoms, tigrbl-base, tigrbl-core.
• External runtime dependencies: numba>=0.61.2.

Usage Examples

Verify the installed package

python -m pip show tigrbl-runtime
python - <<'PY'
from importlib.metadata import version
print(version("tigrbl-runtime"))
PY

Import the package boundary

import importlib

module = importlib.import_module("tigrbl_runtime")
print(module.__name__)

Import a public symbol

from tigrbl_runtime import Runtime

print(Runtime)

Use with the facade when building applications

uv add tigrbl tigrbl-runtime
python - <<'PY'
import tigrbl
print(tigrbl.__name__)
PY

How To Choose This Package

Choose tigrbl-runtime when the quick-answer table matches your use case. Choose tigrbl instead when you want the full public facade. Choose a lower-level package such as tigrbl-core, tigrbl-base, or tigrbl-runtime when you are building framework extensions or testing a specific internal boundary.
