Literature Survey Loop

A search → extract → map → expand loop that builds an evidence/contradiction matrix and stops at saturation. The artifact is the matrix (claims × sources, with each source's stance); the feedback signal is how many new, matrix-changing sources a round adds — you keep expanding until that falls below <min_new> for <patience> rounds. Unlike a one-shot summary, the loop deliberately hunts contradictions and gaps and keeps pulling threads until the picture stops changing.

The discipline: every cell — a source's stance on a claim — is backed by a verbatim snippet from a real retrieval. The value is not a tidy narrative; it is an honest map of where the literature agrees, disagrees, and is silent.

When to use

Use this for a multi-source survey of a question where the deliverable is a structured map of the evidence, not a paragraph. Default: run the full expand→admit→map loop below until saturation. Escape hatch: if the user wants only a quick scan, run round 0 (seed) alone and hand back the seed matrix. Not for grading a written proposal against the literature, and not for proposing new hypotheses.
