Learn

Learn is an optional, off-path consumer of bounded native episodes, verdicts, checks, BD handoff facts, Git changes and user corrections. It is the compatible entrypoint for Memory's mine/learn operation. Read that reference when invoked; do not require Learn to finish ordinary work.

Resolve the caller-selected source set, access, question, consumer and separate budget. Include failures, corrections, harmful and null outcomes. Return narrow supported observations or no-change; one incident is not a general rule. Search existing topic pages and prefer a qualified update or removal over a file per session. Missing provenance remains a disclosed gap; do not delete unique proof.
