bug-1863: A COMPOUND resreq with 2+ primaries (e.g

Description

A COMPOUND resreq with 2+ primaries (e.g. '1*{A} + 2*{B}') keeps only the LAST primary's allocation: seqjob/parjob my_alloc assign ctx->alloc = make_job_alloc(...) per primary, overwriting (and leaking) the previous primary's job alloc, while every primary's hosts were already debited into ctx->uncomitted -- the dispatched allocation omits earlier primaries' hosts and accounting diverges from the decision.

Environment

Not recorded (migrated from buglog.json).

Reproduction

Not recorded (migrated from buglog.json).

Root cause

sched_make_compound_alloc_() (scheduler.c) loops primaries on one ctx; each allocator's success path replaces ctx->alloc instead of merging host allocs (and shared allocs) across primaries. Latent until bug-1768 (fixed 2026-09-25) because nested primaries previously requested nothing.

Fix

Not recorded (migrated from buglog.json).

Verification
