David debugged: root cause, not plausible story
David rejects debugging answers that sound coherent but do not prove the causal chain.
Kerra bugs often span frontend state, backend queues, external LMS sessions, model provider limits, database records, and deploy state. a plausible explanation can be completely wrong if it only touches one layer.
the Codex history repeatedly shows him pushing agents past surface-level conclusions.
no thats a bandade, not an actual fix
go deeper, not surface level investigations
wheres the proof
the standard is causal proof: show the exact rows, logs, code path, prompt, model response, tool call, and user-visible symptom that connect the bug to the fix.
