The token estimate (chars/4) doesn't account for prompt overhead, markdown formatting, and file path wrapping. 75% of context window was too tight. 50% gives enough room. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

Summary
Pre-pass chunks at 75% of context window were still exceeding the token limit due to prompt/formatting overhead not accounted for in the estimate. Dropped to 50%.
