AI Decision System
Replayable, offline-verifiable records for AI-assisted go/no-go decisions.
Site, schemas and conformance vectors: https://bichengwang.github.io/ai-decision-system/
Why
Model output is not authority. Promotions, approvals and releases need a record that a third party can re-check against frozen inputs and rules. Dashboards and logs can describe what happened; re-verifiable evidence also preserves what is needed to recompute the decision.

The arrows show possible decision points, not implemented cross-package connections. Each emits a machine-checkable record; verification mechanisms and retained-input needs vary. See Decision record conventions.
Components
| Component | Decision point | Package | Record and offline check | Status |
|---|---|---|---|---|
| Jev decision | Typed yes/no, choice and score answers; labeled quality gates | jevdecision | Typed answer, evaluation.json, provenance; jev-decision-verify answer.json, jev-decision-eval --responses … with retained questions/cases/requirements | 0.1.0 on GitHub and PyPI; schemas, verifier and signing arrive in 0.2.0 (unreleased on main) |
| decision-control | Frozen routing policy, human approval and local ticket action | decisioncontrol | Exported record; decision-control replay --record … | 0.1.0 on GitHub and PyPI; registry, OPA/Cedar adapters, LangGraph example and signing arrive in 0.2.0 (unreleased on main) |
| Experiment gate | SHIP / HOLD / ROLLBACK / INVALID from exported A/B aggregates | expgate | decision.json; experiment-gate-verify … | 0.1.0 on GitHub and PyPI; schema 3, GrowthBook importer and signing arrive in 0.2.0 (unreleased on main) |
| RELIA | Synthetic model release and guarded update | Not published | results.json, MANIFEST.json; python -m relia.compare … --protocol … in its environment | Unreleased; human-gated |
The three small packages require Python 3.11+ and use only the standard library
at runtime. decision-control is a trusted local SDK/CLI, not an identity service
or external executor. Experiment gate consumes summaries; it does not run an
experiment or deploy a model. Jev supports Jev and OpenAI Decisions backends;
provider-reported confidence is not a calibrated safety guarantee, so on main
jev-decision-eval can fit a calibration on one labeled set and measure it on held-out cases.
Since 0.1.0, main also has (all unreleased; see each CHANGELOG): JSON Schemas and
conformance vectors for every record type, re-checked by an independent Node job
(scripts/conformance); RFC 8785 digests in the
current schemas; jev-decision-verify; optional signed records (--sign-key,
--require-signature: an in-toto Statement in a DSSE envelope, HMAC in-package,
Sigstore through external cosign); an action registry with OPA and Cedar adapters
and a LangGraph approvals example in decision-control; and
experiment-gate --from growthbook. These bridges and fixtures are
software-behavior evidence on synthetic data; no outside use is claimed.
A signature shows the holder of a key signed the bytes, not who that person is.
Quickstart from a clone
Use Python 3.11+ in a virtual environment. For the published 0.1.0 packages:
pip install expgate jevdecision decisioncontrolFeatures documented on main beyond 0.1.0 arrive with 0.2.0, which is not
published yet. Until then, install each independent project from source:
pip install "git+https://github.com/BichengWang/ai-decision-system#subdirectory=ai-workflows/experiment-gate"
pip install "git+https://github.com/BichengWang/ai-decision-system#subdirectory=ai-workflows/jev-decision"
pip install "git+https://github.com/BichengWang/ai-decision-system#subdirectory=ai-workflows/decision-control"Run the examples below from a clone's repository root, with new output paths. Examples are in the source tree/sdist, not installed as wheel package data.

cat /tmp/control-new/summary.jsonThe 0.1.0 packages are on PyPI with trusted-publishing attestations; 0.2.0 remains
unreleased. Live Jev calls require
TYPESAFE_API_KEY (Jev) or OPENAI_API_KEY (OpenAI). The examples above make no
provider calls and use hand-written/synthetic fixtures. They are software checks,
not live-model, calibration, adoption or production evidence. Hashes detect
change, not forgery; identities are caller-asserted and provider origin is not
authenticated.
How this differs
These tools complement existing platforms; the bounded contribution is retained, re-checkable decision evidence, not a replacement for their operational features.
| Category | Typical role | This repository's scope |
|---|---|---|
| Experiment platforms (GrowthBook, Statsig, Eppo) | Compute and manage experiment statistics in a platform | expgate consumes exported aggregates (a GrowthBook results export can be imported) and emits a re-verifiable promotion decision |
| Policy engines / human review (OPA, Cedar, LangGraph interrupts) | Decide authorization or pause a workflow for review | decision-control freezes policy, proposer and review into replayable evidence with label-based separation of duties; it can freeze an OPA or Cedar decision and has a LangGraph approvals example |
| Evaluation tools (promptfoo, OpenAI Evals) | Score prompts and model behavior | Jev gates typed answers with explicit PASS/FAIL/UNGATED and refusal/unknown-confidence semantics |
| Registries / monitoring (MLflow, Evidently) | Track models and monitor performance | RELIA provides byte-reproducible synthetic release gates in its pinned environment |
RELIA uses its own Python 3.13 environment (3.13.7 pinned for reproduction). Its reproduction protocol requires fresh runs and separate reference comparison/reviewer attestations. Synthetic results do not establish real-world commercial performance, fairness, legal compliance or consumer benefit. Thresholds are proposed engineering gates, not industry/government standards; no agency endorsement is claimed. No accepted RELIA public release is claimed. Rights clearance, unaffiliated reproduction and acceptance remain human-gated.
Workspace navigation and validation
The workspace guide and manifest
register independent environments, ownership, CI checks and commands.
With Python 3.11+ resolved as python3:
make workspace-list
make workspace-check
make affected BASE=origin/main
make affected-test BASE=origin/main
make workspace-test COMPONENTS="experiment-gate jev-decision decision-control"
make release-status
make records-demo DEMO_OUT=/abs/new/dirworkspace-check tests tooling and checks syntax, boundaries, CI consistency and
Markdown links; it does not run every behavioral suite. affected-test needs
prepared component environments. release-status inspects candidate metadata
(Python 3.11+). records-demo writes and verifies experiment records, runs Jev
fixture replay, then exports/replays a local review record; it requires an absolute
new directory and prints retained record paths. See the Makefile.
For RELIA use make relia-sync, make relia-test and
make relia-reproduce RELIA_OUT=/abs/new/dir; a local pass is not release acceptance.
The older src/ research workbench has a separate root
environment. Its limited service-free make test baseline uses Python 3.11
(the pinned pandas 1.5.3 lacks Python 3.12+ wheels); broker, browser and ML probes
need separate services/environments. Root tests do not validate the whole repo.
Licensing and project guides
The three small packages carry their own MIT licenses; the root MIT license covers the research material within its scope. RELIA's license status grants no current rights; intended Apache-2.0 publication requires rights clearance. See SECURITY, CONTRIBUTING, CITATION, records, releasing, pilot protocol template, regulatory mapping (draft, no compliance claim), documentation index and plan.
