Retrieval is the cognitive mechanism by which stored information is accessed and brought into active conscious processing. Parameters: (1) target — a previously encoded and stored memory trace; (2) cue — internal or external stimulus that triggers the search; (3) output — the recovered information, which may be complete, partial, or distorted. Persistence mechanism: cognitive science research, pedagogical practice, and linguistic convention maintain retrieval as a distinct concept from encoding, storage, and recall. Retrieval differs from mere recollection in that it includes both intentional and involuntary access, and from recognition in that it requires production rather than identification. The study of retrieval — including retrieval practice, retrieval-induced forgetting, and cue-dependent forgetting — establishes it as one of the three core processes of the memory system alongside encoding and storage.

Definition
Why it is in scope
The cognitive process of accessing and bringing stored information to conscious awareness. Human-made as a scientific concept: the map of the faculty of recall, distinct from the natural memory process itself. Central to learning science as both a demonstration and strengthening mechanism.

Test: which came first? Memory (the human-made concept of storing and retaining information for later recall) predates retrieval (the structured practice of accessing stored information). One must first conceptually understand storage before developing the concept of accessing it. Memory as a conceptual category existed first and fed into the development of retrieval as a distinct concept — from simple recall to indexed search to database query. The concept of retrieval is built on the prior concept of memory.

Retrieval is built and maintained for the sake of decision-making: information retrieval provides the data and evidence that decisions require. By design, retrieval exists to feed informed choices.
- storageDEPENDS_ON →
Retrieval is the process of obtaining items; without storage there is no persistent source to retrieve from, so retrieval stops operating when storage is removed.

indexing is built and maintained for the sake of retrieval: its designed purpose is to structure and direct access to stored information so retrieval can operate efficiently. Per Law 8d, the servant (indexing) points at the master (retrieval). Unlike DEPENDS_ON, SERVES says nothing about whether retrieval collapses without indexing — only that indexing exists to serve retrieval's operation.

Reranking is designed and maintained for the sake of improving retrieval quality. Its entire purpose is to take the output of an initial retrieval and reorder it for better relevance — the servant (reranking) points at the master (retrieval). Removal test: without reranking, retrieval still operates but with lower precision; reranking exists specifically to serve better retrieval outcomes.
- cmsnhnjxs03yq1q13fwu9obkz← DEPENDS_ON
Removal test: remove retrieval and reranking stops operating — it has no candidate set to reorder. Reranking is a post-processing step that operates on retrieval output; without retrieval as input, the reranking function has no purpose and no data to process. This is constitutive at the operational level, not merely sayable.
- storage← SERVES
storage exists to enable retrieval — data is stored for the sake of being retrieved later. The servant (storage) points at the master (retrieval). Storage is built and maintained for the purpose of enabling future access.

An index is built specifically to enable retrieval — its design purpose is to make it possible to find information by organizing entry points to content. For whose sake? Retrieval. The index points at retrieval as its master.

Canonical references, standards, and authoritative forms serve retrieval — they provide trusted, indexed, and easily locatable information. A canonical entry in a knowledge base is designed to be found and relied upon. Servant→master per Law 8d.
