adaptive-compaction

Adaptive add-on policy and recovery layer that decides WHEN a coding agent should compact, prune, snapshot, or fork -- replacing fixed-percent auto-compaction across Claude Code, Codex, and MCP-capable hosts. Deterministic 4-signal scorer (headroom/relevance/burden/continuity), zero-LLM pruning, state snapshots with secret redaction, host-capability-aware downgrade, self-installing hooks. Does not compact for you: it flags the moment + snapshots state + gates a triggered compaction; user runs /compact. No model calls, no network.
