Overview

Server middleware. Runs around ‘perform` for any job carrying a `bid`. On success → BATCH_ACK_SUCCESS → if pending hit zero and no deaths, enqueue `:success` callback jobs; if live jids hit zero, enqueue `:complete` callback jobs.

On a job raising (and thus heading to retry), records a transient failure → BATCH_ACK_FAILED → the jid joins ‘b-<bid>-failed` and `failures` reflects the count of currently-failing jobs. A later successful retry clears it; a terminal death moves it to `b-<bid>-died`. Clean handled exits (JobRetry::Skip from expiry/interrupt, cooperative IterableJob interruption) are re-raised without counting as failures.

Invalidated batches short-circuit: the job is skipped without raising — counts as a “success” for batch purposes per spec §12.

Death handling lives in Wurk::Batch::DeathHandler (registered as a config death_handler) because death is signalled from the retry layer, not from this middleware’s rescue path.
