The daemon handed every index worker aggregate/physical_job_limit (a
fixed quarter by default) regardless of how many jobs were running, so a
lone worker on a host like #1864 was capped at a quarter of the memory
the daemon itself was allowed — and with the budget now failing whole
(decision A) that fixed slice would have turned an idle host into a
guaranteed over_memory_budget. Decision 2 (#1997, #832): the slice is
decided at spawn time as aggregate / jobs active right then (the job
being spawned included), so a lone worker may use the whole aggregate
and concurrent jobs split it. The explicit CBM_MEM_BUDGET_MB override
keeps its precedence inside the worker (bf46b91f); the sub-byte-per-slot
guard is unchanged. The spawn line logs project, active_jobs,
aggregate_mb and slice_mb so a fail-whole verdict can be read against
the budget the worker really had.
Tests: sequenced admission proves first=aggregate, second=aggregate/2;
the racing 4-way admission test accepts any aggregate/1..4 slice (the
divisor is scheduling-dependent there); a scripted CLEAN worker
returning the over_memory_budget error response is passed through
verbatim on the first attempt — no recovery loop, no quarantine.
