Core meaning
- Capability purpose
- Make context selection governable and explainable independently of the model or consumer that uses it.
- Meaningful outcome
- A bounded context package and receipt identify what was selected and why.
- Boundaries — includes
- request purpose, active scope, authorization filters, candidate retrieval, ranking, limits, source references, graceful degradation, and receipt.
- Boundaries — excludes
- answer generation, source-truth mutation, consolidation production, allocation changes, and provider routing.
- Terms and concepts
context package is selected information for a downstream consumer; context receipt records selection provenance and policy.
Interaction Contract MLEs
Assemble context
- Actor
- An authorized application, agent, or workflow preparing a governed operation.
- Command / intent
- Assemble relevant context for a stated purpose and scope.
- Current state
- Governed sources and policy are available; the request has identity and purpose.
- Policies / invariants
- Filter by authority before ranking; respect scope and exclusions; enforce bounded cost/size; preserve source references; record policy and rationale; missing optional sources do not cause fabricated context.
- Transition
- Resolve policy, identify eligible candidates, rank and select them, package the result, and create the receipt.
- Result
- A bounded context package and selection receipt, or a reasoned failure.
- Events / effects
- A downstream generation or execution capability may consume the package.
- Unknowns
- Universal ranking, tier count, and receipt-retention duration are not established.
Rules and defaults
Rules / invariants
- Context assembly remains separable from model generation.
- Ineligible content is excluded before semantic ranking or model exposure.
- Selected content remains attributable to source references.
Recommended defaults
- Prefer deterministic ordering for equal inputs and policy versions.
- Prefer direct recent context before broader derived recall when both are eligible.
