Runtime Authority Contract Source-Signal Handoff

Local semantic retrieval authority now depends on runtime source-authority proof.

The Single Idea

AIN-510 local exact-cosine authority now depends on the promoted runtime contract source-authority signal. The engine can no longer request local semantic retrieval authority from AIN-510 proof alone; it must also prove that production_runtime_contracts_v1 is present, valid, local-only, abstention-aware, and carrying source-authority repair metadata.

01 · What Changed

The AIN-510 switch now reads the promoted contract.

ain_510_runtime_authority_contract_v1 now reads the generated production_runtime_contracts_v1.json receipt. The authority contract requires that receipt to be present, valid, local-only, abstention-aware, and carrying source-authority metadata before local exact-cosine authority can be granted.

AIN-510Exact-cosine vector proof stays necessary for local semantic retrieval.

Runtime ContractsSource-authority and JD blocker status must be visible and passing.

FallbacksDeterministic fallback and rollback remain required before any local authority switch.

02 · Current Proof

The real receipt allows local-only exact cosine.

Field	Value
Status	`local_exact_cosine_authority_allowed`
Valid	`true`
Failed checks	`[]`
Source-authority signal required	`true`
Source-authority contract source	`production_runtime_contracts_v1`
Source-authority repair decisions	`4`

Source-authority status	Count
`deterministic_payload`	965
`source_authority_incomplete`	35
`runtime_payload_backstop_with_source_conflicts`	2
`jd_context_authoritative_backstop`	1
`jd_context_confirmation_blocked`	1

03 · Validation

The focused and full checks pass.

Check	Result
Focused pytest	`8 passed`
Ruff	`All checks passed`
AIN-510 runtime authority contract	`local_exact_cosine_authority_allowed`
Full validation	`pass`

04 · Boundary

No production boundary moved.

No live Gemini call was made, no production runtime was unlocked, no real-user data or external writes were introduced, and runtime embedding authority remains unpromoted.

05 · Next Move

Build the local role-context query surface next.

The next slice should add a local role-context query surface that reads RoleResolutionDecisionV1.source_authority_status and routes each title through serve, fallback, abstain, or confirm-more-context. That is the production path for ambiguous titles like case manager, web designer, and director bi.

06 · Resume

Start from the authority contract.

cd /srv/aina/aina-data-engine-room
git status --short --branch
uv run aina-data-engine --root /srv/aina/aina-data-engine-room ain-510-runtime-authority-contract --request-local-authority
uv run aina-data-engine --root /srv/aina/aina-data-engine-room production-runtime-contracts
uv run aina-data-engine --root /srv/aina/aina-data-engine-room validate

Where to start

Use the source-authority status as the runtime routing signal, not as a report-only decoration.
