  {"id":"O3","fact":"Fresh uncached source read succeeds with verified same current token identity","interpretation":"Whole credential expiry less plausible; read success does not prove write access"},
  {"id":"O4","fact":"Authorised grant/config comparison shows job selected read-only connection; expected write-capable connection differs","interpretation":"Missing write capability contributes; identify who/what changed selection before claiming cause"}

 "hypotheses":[
  {"name":"Parser regression","test":"Bypass new transformation using previously accepted fixture under same boundary conditions","ifSuccess":"Inspect changed transformation","ifDenied":"Inspect write authority/path first; do not claim parser proven correct"},
  {"name":"Whole credential expired","test":"Check fresh permitted read and credential expiry metadata with same actual token identity","ifExpired":"Renew by permitted procedure and recheck","ifReadSucceeds":"Do not assume write access; inspect grant/resource permissions"},
  {"name":"Wrong or reduced write capability","test":"Compare selected connection identity, granted operations and resource access to expected job configuration","ifMismatch":"Owner decides correction; no arbitrary scope expansion","ifMatch":"Inspect provider denial details and resource policy"}

 "mitigation":"Preserve source data and mark report stale; stop blind automatic writes while classification is established",
 "nextProof":"After approved configuration correction, bounded write to a designated test resource, then verify the intended report update independently"
