**Continuous, Verbatim Context Compaction for Autonomous Coding Agents**
*Never lose an exact line number, compiler error, or user constraint to lossy LLM summarization.*

The Problem: Lossy Summarization Breaks Agents
When an AI coding agent runs for 20+ turns, its conversation context approaches LLM window limits. Standard agent frameworks solve this with **summary compaction**: asking an auxiliary model to write a prose summary of older turns.
[!WARNING] **Summary Compaction is Destructive**:
- File paths (
src/core/auth/tokens.tsbecomes "the auth module")- Exact error traces (
Expected 200 OK, got 403 Forbidden at line 48vanishes)- Strict user constraints (
"Never edit files under src/generated") are often dropped or hallucinated away- Re-running tasks becomes erro
