The user-global instruction scope now reads two roots: $DSH_HOME/AGENTS.md
first, then the shared agents root that other agent tools use
($DSH_AGENTS_HOME, else ~/.agents). Both resolve from the process environment
through @deepseek-ai/dsh-home-paths; no config field is added, because the
stack base (PR #5718) removed the per-row home override.
The two files are candidates of one candidate group: identical trimmed content
renders once from the harness home, an unobservable candidate preserves the
group's last-good state, and reconciliation probes both roots so external
edits, removals, and new files become visible change notices. A candidate
dropped as a duplicate keeps being reconciled, so deleting or changing the
retained candidate promotes it. The harness-home file keeps its recorded
`user-global` scope key; the shared file carries `agents-global`.
A user-global delta states `These user-global instructions apply to all work.`
instead of naming its reconciliation scope, and a project path whose first
component would collide with a user-global scope directory renders with a
leading `.` so it keeps its own scope.
