Bounded AI OS-Object Family Baseline (2026-04)

This note marks the first invariant-stable baseline for the current bounded deterministic AI OS-object family in T81.

It is intended as a rollback and reference anchor, not as a claim of general system completeness.

For the single-source freeze document that states what is actually frozen and excluded, see STABLE_BASELINE_CONTRACT.md.

Baseline Identifier

• recommended tag: baseline-bounded-ai-os-object-family-2026-04-02

Included In This Baseline

• validated bounded composition family:
  • assess-fixed
  • route-fixed
  • classify-fixed
• shared typed object pipeline using the current helper surface
• canonical bundle as the top-level persisted object for each validated chain
• Canonical Identity Invariant documented for the validated family
• cross-root validation for identical task/model/policy/input across:
  • result artifact
  • provenance artifact
  • downstream record
  • canonical bundle

What Is Validated

For the current validated family, identical task, model, policy, and input produce identical:

• result_ref and result bytes
• provenance_ref and provenance bytes where checked
• record_ref and downstream record bytes
• bundle_ref and final bundle bytes

Those identities are root-independent across different CanonFS roots.

What Is Explicitly Not Claimed

• no fourth composition is implied
• no open-ended orchestration is implied
• no generalized schema family is implied
• no general AI runtime completeness is implied
• no future composition inherits the invariant automatically without its own proof

Intended Use

Use this baseline as:

• a known-good rollback point
• a reference anchor for future bounded-family work
• a control point for detecting drift in object identity, helper contracts, or bundle discipline

Reference Surfaces Frozen By This Baseline

• canonical newcomer-facing explainer:
  • FIRST_DETERMINISTIC_AI_OS_OBJECT_CHAIN.md
• bounded family catalog:
  • AI_OS_OBJECT_CHAIN_CATALOG.md
• shared framework contract:
  • AI_TASK_SHARED_FRAMEWORK_CONTRACT.md
• current runnable examples:
  • run_assess_fixed_host_action.sh
  • run_route_fixed_path_selection.sh
  • run_classify_fixed_rule_selection.sh

Current Boundary

This baseline preserves a small bounded family only.

It does not promote:

• a workflow engine
• a general packaging system
• a rule execution engine
• agents
• orchestration
• broader inference claims than the currently validated family supports
