Compaction summaries were capped at 80 percent of reserve tokens, turn prefixes at half, and branch summaries at a hard-coded value. On providers where reasoning shares the output limit, like OpenAI Responses and adaptive…
Second theme is provider reliability and plumbing. Commit 4dd2b14 treats whitespace-only tool output as empty, after bare newlines from shell tools were triggering repeat 400 errors on OpenAI and Google. Commits 698a2d2 and 0fbdbd3 expand automatic retries for gateway upstream failures and for Vertex token refresh…
