Per-session policy overrides (sandbox/mode, approval/policy) never crossed
the delegation boundary: a spawn child of a read-only-switched parent ran
under the wider deployment default, and a fork child missed any switch made
after its seed boundary — delegation was a bypass channel for a user's
tightening.
The in-process driver now snapshots the delegating parent's override chain
and stamps it onto the child through the canonical write paths
(SandboxPolicyService.inheritOverride / ApprovalService.inheritOverride),
anchored inside the child's first turn via a one-shot agent/prompt-submit
listener: turn-enclosed (durable), ahead of the first request (an inherited
'never' reaches the child's first system prompt), and positioned after any
stale fork-seed switch so the ordinary last-event-wins fold resolves it.
Only overrides are copied — an unswitched parent stamps nothing and the
child follows the live deployment default; both services are consumed
opportunistically, so compositions without them delegate unchanged. Nesting
composes by construction (each stamp folds the already-stamped parent log).
Evidence: inheritance.spec.ts drives scripted-model children into the real
dsh-fs-sandbox fence through the real write tool (disk-state + denial-marker
assertions; spawn, stale-seed fork, grandchild, escalation fail-closed, and
no-stamp guards), inheritOverride contract tests in both service suites, and
the recorded subagent-sandbox-inheritance ACP snapshot (read-only preset →
delegate → child denied, replayed keylessly).

Address a fresh-eye review of the disposal/injection fixes:
- disposal now snapshots, clears, and marks disposed BEFORE emitting
agent/inbox/discard (mirroring cancel's snapshot→clear→emit), so a
re-entrant send/cancel from a discard listener throws 'disposed' or
finds an empty inbox instead of leaking or double-discarding an id.
The discard is unconditional (even on unpublished setup-rollback) to
match send's unconditional enqueue, keeping every id balanced.
- restore the turnRecorded guard on the idle-injection flush: a
turn/start rejected pre-commit (append reentrancy / internal-dispatch
veto) records nothing and owes no flush; the previous unconditional
flush emitted a phantom-turn agent/error. The isTurnOpen/turnRecorded
branches are reachable (reentrant inject from a session/event
listener) and now covered by a regression test rather than v8-ignored.
- rewrite the agent/inbox/discard event JSDoc to enumerate all three
emitters (cancel, terminal turn-stop, disposal) — every enqueued id
gets exactly one terminal dequeue-or-discard.
Per-file coverage stays 100%.
The loading-chain RFC (2026-07-23-client-plugin-loading-model, en/zh)
states the shipped model in its final form: two package kinds (dshClient
means plugin), one module system + one plugin governor, the end-to-end
loading flow, and hot reload with its support boundary — written for a
first-time reader, no intermediate-design narration. The two 2026-07-19
GUI RFCs defer their loading-chain sections to it and drop stale
vocabulary. config-catalog regenerated for the package rename; pairing
manifest tracks the renamed pair.
ui-question landed on master as a full dshClient plugin package (composer
question flow); it enters the flat roster, apps/cli deps/refs, and the
smoke graph. Restore the workspace-context and user-interaction host deps
the conflict resolution had dropped.
