<section class="section limits"><div class="eyebrow">05 / The fine print, in normal-sized type</div><h2>Selection. Not magic.</h2><p>This is a standalone offline selector, not live compaction and not an integration with Claude Code, Fly or Boring. It accepts ordered user/assistant/tool JSONL and message-wrapped user/assistant records; metadata rows, branching histories and incomplete exchanges are rejected. Normalize unsupported exports first. There is no tokenizer, summarizer, secret scrubber or semantic dependency analysis. Inspect the packet before sharing it.</p><p>Pinned payloads remain verbatim inside Markdown JSONL blocks. Unpinned exchanges can be omitted. The manifest tells you exactly which ones. A selected exchange keeps all its tool calls and results. Selection does not guarantee an assistant will obey the continuation.</p><p>The board’s upstream reference is <a href="https://github.com/anthropics/claude-code/issues/83489">anthropics/claude-code #83489: named model + effort presets</a>, closed as not planned. That issue asks for presets; this venture implements the board’s separate context-priority brief. It does not implement model presets and is not affiliated with Anthropic.</p></section>
