Layered context recall for a project: wiki (map) → code (detail) → memory (prior session learnings). Bounded output; honest per-layer status. project defaults to whatever the projects file says the working directory belongs to, falling back to its name; layer = auto|wiki|code|memory.

Deposit ONE learning into the project's episodic memory (staging area). kind may carry a module prefix for consolidation routing, e.g. 'rag:gotcha' or 'config:decision'. Learnings only — routine actions are logging, not learning, and belong in session transcripts.

supersedes names an existing note (the short id recall prints, or a unique prefix of it) that this one replaces. The old note is marked as replaced and stops being returned, but is kept, so the change is reversible and you can still see what the earlier fact was. Use it instead of rewriting history.

Withdraw a memory note that nothing replaces — a fact found to be wrong, or one that no longer applies. The note stays in the store (so the withdrawal is reversible and the history readable) but recall stops returning it.

node_id is the short id recall prints, or any unique prefix of it. An ambiguous or unknown reference changes nothing and says so.

Layer counts + wiki-earn suggestion for a project. The suggestion rule: (≥3 sessions AND ≥5 learnings) OR (≥3 architecture-phrased recalls) on a project with no wiki → suggest generating the wiki.

Index a repo's source files into the project's code layer. Skips vendored/binary/hidden dirs; deterministic IDs make unchanged chunks idempotent; rebuild=True drops stale chunks of edited files.

(Re)index a code-wiki directory (markdown) into the project's wiki layer. Heading-aware chunking keeps ## sections atomic.
