Most of what's written about STIV's approval model describes the version where everything works: an agent drafts, a human reviews, a mistake gets caught before it ships. That's the common case, but it isn't the only one worth being honest about. Sometimes something ships and turns out to be wrong anyway — an approved report used a stale reconciliation, a redline missed a clause a playbook hadn't anticipated. What happens then is the more interesting question.
Reversible means something specific, not just an adjective
Every action in STIV's audit trail is logged, timestamped, and reversible — described in general terms in our security architecture piece. In practice, "reversible" means the system retains what changed, what it was before, and who approved it, so correcting a mistake doesn't mean reconstructing what happened from memory or a scattered email thread. The correction itself becomes a new, equally logged entry — not a quiet edit to the original record.
The difference between a caught mistake and a shipped one
- A caught mistake — rejected or edited before it goes out — is covered by the approval gate itself, and the three outcomes described in what a rejected approval actually looks like.
- A shipped mistake means a human already approved something that turned out to be wrong — the gate did its job of requiring sign-off, and the sign-off itself was the point where the error passed through.
- The fix in both cases routes through the same accountable review process — nobody quietly patches an output without the correction landing in the record.
- A pattern of shipped mistakes on the same clause, line item, or ticket type gets treated as a playbook gap to close, not an isolated incident to apologize for.
Why this doesn't undermine the approval model
A system that never makes a mistake that reaches a human isn't a realistic claim, and STIV doesn't make it. The claim that matters is narrower: nothing an agent does is untraceable or unrecoverable, and a wrong output is a correctable, logged event rather than a silent failure discovered weeks later. That's a materially different guarantee than "this won't happen," and it's the one that's actually verifiable.
If a vendor's answer to "what happens when it's wrong" is a claim that it won't be, that's worth more suspicion than a straight answer about how the correction gets made and recorded. The approval gate reduces how often something wrong ships; the audit trail is what makes it survivable on the occasions it still does.
