context_summarizerlisted

# context_summarizer Compress long traces / conversations into recoverable AAAK blobs. ## Operations - `ctx.summarize(text, target_tokens, anchor_hints?)` — produce AAAK blob. - `ctx.expand(blob)` — reconstruct best-fidelity form. - `ctx.rank(chunks, query)` — relevance scores for eviction. - `ctx.evict(segments, budget)` — compose an eviction plan. ## I/O Contract ```yaml io_contract: input: { op, args } output: { result } idempotent: deterministic_with_seed side_effects: [] ``` ## AAAK Adaptive Anchored Attention Keys — lossy-compressed format with recovery anchors. Written to MemPalace as native `.aaak` blobs.
