This diagnostic has eight immutable IDs, limits 2..10000, explicit /run
scheduling and startup replay. It is serial, header-only ASCII HTTP, with no
authentication or baseline idle-client timeout. Forward only host loopback.
Ordinary process restart/reboot are verified. Staged writes plus rename are
not a power-loss atomicity, fsync durability or exactly-once execution claim.

REAL SlOS + compiled Hew durable prime jobs (host-side exact HTTP checks)
POST accepts a durable queue entry; POST /run starts work; startup recovers pending entries.
