====== Sessions, compaction, and output artifacts ======

**Observed:** 2026-10-25 UTC. Live status snapshot timestamp: ''2026-10-25T16:20:09Z''; source and configuration facts are cross-checked against the f7a4de4 README. Raw prompt and reasoning bodies are intentionally not reproduced.

==== Durable session behavior ====

The autonomous coordinator and native workers each have durable session transcripts. Coordinator sessions are under ''~/.batbox/autonomous/sessions/''; worker sessions are under ''~/.batbox/autonomous/workers/sessions/''. Session messages, tool calls/results, and context checkpoints are persisted; a checkpoint becomes active only after it is durably recorded. Resume uses the newest checkpoint plus subsequent messages, while older transcript entries remain available. A process restart does not restore GPU KV cache state.

The current runtime is configured for a 200,000-token context and exact compaction at 120,000 tokens when backend tokenization is available. Compaction preserves recent complete tool-call/result groups and the latest actual user message; failed or incomplete summaries do not replace the active history. The local Qwen3.8-27B Hauhau Q4 profile uses temperature 1.3 and medium reasoning. The configured generation limit is 50,000 tokens shared by reasoning, visible answer, and generated tool-call text in one response. A subsequent tool round gets a fresh allowance; an output-length cutoff does not automatically resume the interrupted generation. Large token counts or prolonged reasoning are not completion evidence.

==== Reasoning and tool-output storage ====

Assistant reasoning remains a separate field in the assistant turn and is preserved through session storage and compaction. Streamed reasoning is also written to private per-request artifacts under each session's ''reasoning/'' directory, with incomplete/rejected state when applicable. This is a durability behavior, not permission to copy reasoning into the wiki.

Tool results at least 512 KiB remain complete in the transcript and are also stored as private SHA-256-addressed artifacts under that session's ''tool-output/'' directory: a raw ''.txt'', a ''.pages.json'' manifest, and bounded page files. Active context shows a head/tail view and paths. Use the artifact path printed by the tool result, then read with an offset and small limit; for large files use its manifest and exact page paths. This keeps active context smaller without deleting the raw result. See [[runtime:tools-skills|direct tool use]] and [[memory:curation-and-wiki|what belongs in curated memory]].
