AI OS-Object Chain Catalog

This document lists the current bounded deterministic AI OS-object chains in T81.

For the newcomer-facing explanation of the current canonical runnable chain, see FIRST_DETERMINISTIC_AI_OS_OBJECT_CHAIN.md.

These chains are:

• deterministic
• policy-gated
• typed
• CanonFS-backed
• helper-driven

They are not a workflow engine or a general orchestration layer. They are a small bounded family of reusable compositions built on the current AI task and artifact helper surfaces.

The admission gate for any future family member is defined in AI_OS_OBJECT_FAMILY_ADMISSION_CONTRACT.md.

The narrow external-consumption contract for the current canonical bundle is defined in AI_OS_OBJECT_BUNDLE_CONSUMPTION_CONTRACT.md.

The narrow .v1 versioning boundary for that bundle surface is defined in AI_OS_OBJECT_BUNDLE_VERSIONING_BOUNDARY.md.

Confirmed invariant:

• for identical task, model, policy, and input, the current chains keep the same content-addressed object identity across repeated runs and across different CanonFS roots
• for the validated assess-fixed chain, the canonical final bundle also keeps the same content-addressed identity across different CanonFS roots
• for the validated route-fixed chain, the canonical final bundle also keeps the same content-addressed identity across different CanonFS roots
• for the validated classify-fixed chain, the canonical final bundle also keeps the same content-addressed identity across different CanonFS roots

Assess-Fixed Host Action Chain

Purpose:

• run one bounded governed assessment task
• turn the stored AI result into one fixed downstream host-action decision
• persist the completed chain as one canonical bundle object

Task schema/result family:

• task: assess_fixed.v1

• provenance artifact schema: t81.ai.task.provenance.v1

Downstream record schema:

• t81.ai.task.assess-fixed.host-action-record.v1

Final bundle schema:

• t81.ai.task.assess-fixed.bundle.v1

Object roles:

• task result artifact: intermediate
• provenance artifact: intermediate
• downstream record: intermediate
• final bundle artifact: canonical

Canonical runnable example:

• run_assess_fixed_host_action.sh

Portable proof path:

Classify-Fixed Rule Selection Chain

Purpose:

• run one bounded governed classification task
• turn the stored AI label result into one fixed downstream rule-set selection
• persist the completed chain as one canonical bundle object

Task schema/result family:

• task: classify_fixed.v1

Canonical top-level object:

• the stored bundle t81.ai.task.classify-fixed.bundle.v1

Boundary

This catalog covers the current bounded reusable composition family only.

The current posture for this family is stabilization and misuse-path hardening, not automatic growth to a fourth composition.

It does not define:

• a workflow engine
• a general packaging system
• a general AI orchestration layer
• new inference behavior
