Q
What breaks first without staged compression?
Tool outputs: one verbose test run or directory dump poisons every later turn until compaction. Micro caps are the cheapest lever.

Token-Fold.
Compression in three tiers.
Direct answer
Token-Fold is Anvaya's staged compression thesis: Micro (per-tool-call output caps and filters), Meso (per-turn packing under budget), and Macro (cross-session synthesis into threads and nodes). Each tier assumes the last leaks — caps catch verbose tools, packing catches redundant retrieval, synthesis catches repeated history. Design thesis: 100+ tool rounds at stable quality, because no single tier carries the whole burden.

How We Implement It.
01Token-FoldImplemented across anv-agent (caps, guard, accounting, cache) and mind-services (Quorum packing, SessionSynthesizer threads at ~25x).
Questions
Asked About Token-Fold.
Q
How many tool rounds stay stable?
Design target is 100+ rounds at stable quality; measurement trials with published scripts arrive Q3 2026.
Q
Is Token-Fold just summarization?
No — summarization is one Meso tactic. Folding spans caps, packing, caching, isolation, and cross-session synthesis as one budget discipline.
