Retrieval Boundaries
Purpose
This page documents how retrieval scope is defined and constrained so the system accesses only permitted information. This layer exists to prevent unqualified, out-of-scope, or implicitly inferred material from entering the generation path.
In practice, this is the difference between allowing a system to “look anywhere it finds something relevant” and restricting it to retrieve only from sources it is explicitly permitted to use.
It establishes the rules that determine what content may be retrieved, combined, or surfaced during generation, based on prior qualification and metadata constraints.
Scope
Includes definition of allowed retrieval domains, filtering rules, exclusion zones, and handling of out-of-scope or unanswerable queries. Excludes indexing mechanics, ranking algorithms, similarity tuning, and any assumption that broader retrieval improves output quality.
Constraints
- Retrieval is limited to content that has been explicitly qualified and approved for use.
- Out-of-scope, disallowed, or insufficiently qualified material is not retrieved, even when semantically adjacent.
- Boundary rules are enforced uniformly across all queries, sessions, and output contexts.
- When retrieval constraints prevent a valid response, the system surfaces that limitation rather than inferring or fabricating an answer.
These constraints ensure that generation cannot exceed the system’s documented knowledge boundary. Relaxing them introduces silent scope expansion that downstream explanation cannot consistently detect.
Notes
Retrieval boundaries are the primary operational defense against scope creep. Weak, implicit, or inconsistently enforced boundaries tend to produce confident outputs that exceed the system’s actual authority.
