Research infra: freeze Decision Engine V1 CAL Pipeline candidate

[camerontjs-dot]

Classification

Draft Integration Evidence / candidate identity freeze. Documentation/evidence only. Do not merge as a runtime change.

Terminal local-slice status

QUALIFIED_FOR_LOCAL_PIPELINE_RUNS_C1_ONLY

The frozen candidate is not this PR head. It is the already released Decision Engine v1.0.0 object:

• release commit: 7be709b2141c767c5da89b8b94cf90233c4238fe
• release tree: 4e92703e781024de62c77f2f14e9164aceb16815
• annotated tag object: 7835f2f53267843113212abfa0cac6e726242409
• deterministic release archive SHA-256: c440d5de2a3853db9f4ccc2ba37d273e29ce8d9e71e0d646fc0c20eee0cd5902

No Decision research head is promoted or substituted by this PR.

New authority-freeze convention

This record is now aligned to Apparatus Contracts #100:

freeze only state the apparatus uniquely owns and that a legitimate downstream consumer must be able to verify without reconstructing producer-private behavior.

The Decision -> Contract D freeze is explicitly recorded as:

• exact input-authority kind/id/immutable identity;
• exact Decision policy id/version;
• exact target kind/id/content hash;
• evaluation state;
• completed disposition;
• exact typed/versioned normalized effect + parameters;
• Contract D semantic identity;
• metadata explicitly non-authoritative.

CAL semantics, Contract C participant authority, Authorization, actor/delegation state, and execution remain outside Decision authority.

Qualification

Exact release-object qualification already provides the decisive evidence:

• extracted-release smoke: PASS
• deterministic archive rebuild: PASS
• exact Contract C / D authority checks: PASS
• maintained V1 policy cohorts: PASS

Portable local slice

Use the published decision-engine-v1.0.0-source.tar.gz artifact after verifying its recorded SHA-256. The maintained local invocation surface is:

• library: evaluateContractCDecision(options)
• CLI: scripts/decision-engine-evaluate.mjs
• output: canonical Contract D 1.0.0

Boundary that remains live

This qualification is C1-only.

Released Decision V1 does not natively accept Contract C 2.x. The current richer CAL V1 parent/decomposition state also must not be silently discarded or downgraded merely to reach Decision.

Decision PR #75 and successor research PRs preserve C2/successor ingress experiments separately. They do not enter this frozen V1 slice and do not authorize production promotion.

No maintained source, policy, Contract authority, Authorization, execution, tag, release, or production default is changed by this PR.
