Show HN: StaleTrace – A temporal ledger that catches stale-state agent bugs

StaleTrace — stop agents acting on stale state

How it works

From raw logs to a root cause.

Feed it your agent's tool calls and the facts your systems already record. It does the rest — deterministically.

01<br>Reconstruct the timeline<br>Replays your fact events into a temporal ledger, so every value has a window of when it was actually valid.

02<br>Find the bad fact<br>Checks what the agent used against what was valid at that moment — surfacing stale, conflicting, or closed-account state.

03<br>Generate the report<br>Produces a plain-language root cause, a blast radius, and a copyable incident report your team can act on.

Why it's different

It's a ledger, not a model.

No guesses, no embeddings, no second LLM to audit the first. The same inputs always produce the same verdict — which is what you want when you're explaining a production failure. The engine is ValidMemory , a zero-token temporal fact ledger.
