Strip ANSI styling before matching option names, using the existing help-test pattern so CI preserves the same validation assertions.

--max-costand--timeoutto single-prompt headless runs. Keep max turns at exit 3 and reserve provider codes 4–9; context overflow now exits 10, local cost limit or unknown spend exits 11, and execution timeout exits 12.All model calls share cost admission, including workers, subagents, compaction, learning, reviews, and retries. Unknown prices or spend close admission. Already admitted calls can exceed the threshold. The timeout covers MCP connection and active execution; synchronous startup and cleanup remain outside its deadline. Remove the unused
on_overflowsetting and retain partial responses on limits.Regression coverage includes concurrent accounting, unknown prices, cancellation, distinct exits, and cleanup. The following JSON layer preserves limit stop reasons and known partial usage.
Tracks LaFabrique #46.
The foreground-shell timeout regression allows two seconds for startup on slow runners while retaining its timeout exit, shell-start, and terminated-process assertions.

mainat74a5e28into the stack, retaining merged PR #22’s memory improvements and PR #27’s removal of automatic Exa/Context7 servers. Each updated branch retains its previous remote head and preceding stack layer through additive merges. Configured MCP servers remain supported.Repaired the session-name mock at its lazy import location, used schema version 2 in non-persistence fixtures, and removed obsolete MCP flag assignments from the memory regression harness. All existing behavioral assertions are retained. Provider codes remain 4–9; context overflow, local cost limit/unknown spend, and execution timeout remain 10/11/12. The existing memory and usage-accounting implementation is unchanged.
