 - did the run show context pressure, model mismatch, or accounting oddities?
 - which tools did the model try to call?
 
-## What It Cannot Tell You
-
-Codex Blackbox does not see everything Codex does locally.
-
-It cannot prove:
-
-- whether a local tool call succeeded or failed
-- whether an MCP server started, stopped, or failed
-- whether a skill loaded or failed
-- why a permission was approved or denied
-- provider quota, cap, or rate-limit state
-- cache TTL, cache expiry, or cache rebuild timing

-When the report lists tool calls, read that as "the model tried to call this
-tool", not "the tool succeeded".
