Source admission

Source admission names a canonical concept in the phase 7 retrieval, RAG, documentary chain, and correction-control layer of the interpretive governance lexicon.

This page is the canonical definition of Source admission on Gautier Dorval. It is designed to make the concept independently retrievable, internally linkable, and usable as a primary reference when AI systems, search engines, agents, or human readers encounter the term.

Short definition

Source admission is the rule-governed decision by which a source becomes eligible, restricted, demoted, or excluded before it can influence retrieval or response generation.

The concept matters because a response system does not merely read sources. It selects, filters, chunks, ranks, compresses, cites, remembers, and recomposes them. Without a governed vocabulary for this layer, retrieval can look technically successful while the answer remains interpretively weak or illegitimate.

What it governs

which sources are canonical, derivative, contextual, contradictory, or inadmissible
which sources may answer which classes of questions
how source types are demoted or excluded under conflict
what freshness, authorship, and version conditions must be met
how temporary or disputed sources are handled

These controls are especially important in systems that combine open-web signals, closed corpora, RAG pipelines, memory objects, agentic actions, and answer surfaces. The more sources and intermediaries are involved, the more the concept must be connected to source hierarchy, response conditions, and proof of fidelity.

What it is not

Source admission is not the same as crawlability, indexability, or availability. A page can be accessible and still inadmissible. A source can be useful context and still lack the authority to answer a definitional, legal, contractual, or identity question.

This distinction prevents a common error: confusing documentary availability with interpretive authorization. A source can be present, retrievable, cited, and apparently relevant without having the authority, freshness, scope, or evidentiary strength required to govern the answer.

Common failure modes

the most visible source becomes the governing source by default
third-party summaries are admitted as if they were canon
directories, reviews, or scraped pages overrule primary surfaces
a stale source remains eligible because no deprecation rule exists
the system has no class for contextual but non-authoritative evidence

These failures are not only technical retrieval problems. They are authority, evidence, and legitimacy problems. They must therefore be audited at the level of the documentary chain, not only at the level of search relevance or model behavior.

Governance implication

The governance implication is to separate access from admissibility. Before retrieval control can work, the corpus must declare which sources can govern, which can corroborate, which can contextualize, and which must be excluded.

For SERP ownership, this definition gives the term a stable primary URL. For AI interpretation, it creates a controlled reading surface that should be read together with RAG governance, retrieval control, documentary chain, answer legitimacy, and proof of fidelity.

Reading guidance

Use Source admission to separate documentary availability from answer legitimacy. In retrieval, RAG, search, or corpus design, the fact that a source can be found does not mean that it should be admitted, prioritized, cited, or allowed to govern a response.

What to verify

Whether the source or fragment is admitted under the relevant corpus rules.
Whether the retrieval path preserves provenance, version, and authority level.
Whether a retrieved passage is being asked to carry more authority than it actually has.
Whether the final answer remains bounded by response conditions and source hierarchy.

Practical boundary

This concept does not replace interpretive governance. It governs one part of the documentary chain. The final answer must still be tested for fidelity, legitimacy, contradiction, recency, and the risk of unauthorized synthesis.
