The DISCOVER pipeline’s attrition, counted.

“The model contributed nothing” has at least five distinct causes, and they call for opposite responses: an empty bundle is a capture problem, a model that abstained may need better evidence or a better prompt, drafts dying at GROUND suggest fabrication, drafts dying at VERIFY suggest they were vague, and drafts dying at the floor were merely unconfident. Without this they are indistinguishable from the outside — every one of them renders as an empty ledger and reads like a clean null. That ambiguity cost a six-cell measurement run before it was noticed.

Fields

evidence: u64

Grains offered to the model as evidence. Zero means nothing to reflect on.

proposed: u64

Drafts the model returned.

cited: u64

Survived the cite-check and target-class filter.

dropped_uncited: u64

Dropped for citing a hash the bundle does not hold. Its own counter because the fix is specific: models copy long hex badly, and that is a different problem from one aiming at a surface it may not touch.

dropped_target: u64

Dropped for targeting a class the vocabulary may not reach — a prompt, host config, or its own grader.

grounded: u64

Survived GROUND — their premises were found in the cited evidence.

ground_verdicts: u64

Verdicts GROUND actually returned. grounded = 0 with verdicts > 0 is the gate refusing every draft; grounded = 0 with verdicts = 0 is a grader that answered with nothing usable, which is a backend problem wearing a gate’s clothes.

ground_call_failed: bool

The GROUND call itself failed — no response at all. The engine fail-softs here by design, so without this the run looks like a model that had nothing to say.

kept: u64

Survived VERIFY’s adversarial pass.

stored: u64

Cleared the confidence floor and reached the queue.

advisory_thin_evidence: u64

Kept, but demoted to advisory for citing fewer distinct evidence grains than Policy::min_evidence. Omitted when zero, so a run under the default policy reads exactly as before.

dropped_near_duplicate: u64

Kept, but dropped before the queue for restating a live lesson on the same entity in other words (Policy::near_duplicate = suppress). Its own counter beside dropped_uncited and dropped_target, so “the model contributed nothing” keeps its distinct causes. Omitted when zero.
