Scope
Ketju lists an event here when it can change a Ketju memo, a position a client holds, something that position depends on, or the records an advisor should keep. Each entry names the stage the event has reached: reported, proposed, approved, executed, contained, recovered, or explained in a postmortem.
Corrections
Ketju never edits a published version. A recovery, a postmortem, a corrected loss figure, or a changed reading becomes a new version at the same address, and every earlier version stays in the JSON file.
Educational research for financial professionals. Not investment, legal, tax, or compliance advice. An event here does not mean a product is suitable or approved.
