Two branch-only commits each armed a defect in the compose-up handler
topic, and both failed in run 33785198875.

63f7f962bf registered the topic owner at the top of sys-svc-rdbms'
dedicated.yml so the notify two tasks below stopped aborting with
ERROR_ON_MISSING_HANDLER. The notification then survived to the
unconditional meta: flush_handlers at sys-svc-container/tasks/00_core.yml:53,
reached from sys-svc-compose's own 00_core before that role installs
BIN_COMPOSE, and long before 02_stack_host_prep installs BIN_CA_INJECT.
Matrix#1 died there on ca-inject with rc 2 after seven retries. That play
carries exactly one compose notification (job 100756596907, log line
11046), so closing this window is sufficient, not merely necessary.
dedicated.yml now enters 00_core.yml under the role's run-once flag
before it notifies, so the flush drains an empty queue and the flag then
makes main.yml skip the body on the real entry. The registration itself
stays ungated: gating it would skip the owner from the second app on.

95186163aa hoisted the sys-svc-compose include to sys-stk-backend
position 1. The consumer therefore rendered and notified compose-up
before sys-svc-objstore lazily loaded the provider app role, whose own
unconditional flush consumed the notification and ran the single
registered handler in the provider's chdir. mastodon and peertube never
got a stack, in compose and in swarm alike; the victim's own guard task
appears zero times in all four logs. Restoring the include below rdbms,
objstore and engine puts the notify after every foreign crossing. Two
pre-hoist runs in exactly that order are green on record.

The test keeps its cases and gains one. It selects the render include by
the absence of tasks_from instead of by first occurrence, so an early
registration-only include stays legal while a hoisted render still fails.
The new case pins the bootstrap: entry point, position before the first
notify, and the run-once guard whose removal would let 01_reset.yml tear
down DIR_COMPOSITIONS once per dedicated-DB app.

Same class, pre-existing, not fixed here: svc-db-qdrant notifies and
flushes three tasks before its first compose entry; web-app-magento pairs
a dedicated database with a shared object store; web-app-seaweedfs still
flushes a topic it does not own; svc-runner enters 00_core.yml unguarded.
