Record a typed episode to memory. Call this when important decisions are made, patterns are noticed, tensions are identified, questions arise, or outcomes are observed. Record the reasoning, not just the fact — 'Chose X because Y' is more valuable than 'using X'. Episodes accumulate during a session and serve as raw material for compression into the continuity file at session end.

Query episodes from memory with filters. Call this to find prior context before making decisions, to locate specific episodes for citation during graduation, or to review recent work. Returns matching episodes ordered by timestamp (newest first). Supports time range, type, source, and keyword filters.

Prepare a compression package for session wrap. Call this at session boundaries — when work is ending, the user says to wrap up, or the session is getting long. Returns all episodes since the last wrap, the current continuity file, stale pattern warnings, Hebbian association context (which episodes have been thought about together before), and compression instructions. Marks a wrap as in-progress and mints a session-handshake token (shown as 'Wrap token: ' at the end of the response) — round-trip that token to save_continuity's wrap_token argument so the save call can verify it matches the in-progress wrap and catch stale tokens. After calling, follow the returned instructions to compress episodes into an updated continuity file, then save with save_continuity. The compression step is where the real thinking happens — patterns emerge that weren't visible in the raw episodes.

Validate and save the compressed continuity file. Call this after compressing your episodes using the instructions from prepare_wrap. The text must contain exactly 4 sections: ## State, ## Patterns, ## Decisions, ## Context. The server validates structure, checks graduation citations against real episodes (cited IDs must exist), checks explanation overlap (evidence must reference actual episode content), detects citation gaming (suspicious reuse of single episodes), and may demote ungrounded graduations. Also records Hebbian associations between co-cited episodes (episodes cited together on the same pattern line form strong links; episodes cited in the same wrap form weaker links) and decays unreinforced associations. Returns validation results, association metrics, and section sizes.

Delete a single episode by ID. Use this for content that should not exist: accidentally recorded PII, sensitive data, or fundamentally wrong recordings. Do NOT use for factual corrections — record a new episode with the correction instead and let compression resolve it. Deletion cascades: all Hebbian associations involving the episode are removed, and the deletion is logged in the audit trail. By default, a tombstone is preserved as an existence proof for audit integrity: episode ID, original timestamp, episode type, and SHA-256 content hash are retained — the original text is fully erased. Under GDPR framing, the retained fields are pseudonymized metadata, not content; disable tombstones at Store construction (keep_tombstones=False) if even this metadata must not survive. The hash chain remains verifiable either way. This action is irreversible.

Get memory health metrics. Call this at session start to understand memory state, or when diagnosing issues. Returns episode counts (total and since last wrap), wrap history, continuity file size, episodes by type, whether a wrap is currently in progress, Hebbian association network metrics (total links, average/max strength, network density), and audit trail health (enabled/disabled, entry count, log path, retention window). Use anneal-memory verify from the CLI to validate the audit hash chain itself — status() only surfaces cheap health signals, not integrity proof.
