When should I install tigrbl-atoms?

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

Who is tigrbl-atoms for?

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

Where does tigrbl-atoms fit?

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

How does tigrbl-atoms 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-atoms 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_atoms: _ctx, _opview_helpers, _request, algebra, atoms/, events, fallback, phases, protocol_runtime, runtime_callbacks, runtime_channel, runtime_transactions

Public API and Import Surface

• Import roots: tigrbl_atoms.
• Public symbols: EGRESS_PHASES, EdgeTarget, ErrorCtx, HANDLER_PHASES, HookPhase, HookPhases, HookPredicate, INGRESS_PHASES, PHASE_SEQUENCE, PhaseTreeEdge, PhaseTreeNode, StepFn.
• Workspace dependencies: tigrbl-ops-oltp, tigrbl-ops-olap, tigrbl-ops-realtime, tigrbl-core, tigrbl-typing.
• External runtime dependencies: jinja2>=3.1, sqlalchemy>=2.0, typing-extensions>=4.0.

Usage Examples

Verify the installed package

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

Import the package boundary

import importlib

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

Import a public symbol

from tigrbl_atoms import EGRESS_PHASES

print(EGRESS_PHASES)

Use with the facade when building applications

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

How To Choose This Package

Choose tigrbl-atoms 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.
