The doc-typecheck opt-out ratio gate now fails at 74/146 after merging
master. The model and branded-ID blocks are self-contained, so check
them as ordinary ts fences (72/146 remain opted out); re-record the
pairing sidecar.
tool-pwsh now renders sandbox denial facts (denial marker + same-turn escalation hint, runner-failed notice on background reads) and advertises the sandbox_permissions/justification escalation pair resolved through ctx.approval before execution — the shared fail-closed sequence from dsh-sandbox, with the tool name 'pwsh'. The description teaches the ConstrainedLanguage contract under the Windows sandbox (both confined modes run pwsh in CLM: Add-Type, non-core .NET statics, COM, and reflection fail; the mode cannot be lifted — probe-verified, pinned by LANGMODE assertions in the runner suite and description assertions in the tool suite). The stale pwsh-sandbox JSDoc ('the tool owns approval') and the parity notes' superseded 'minus sandbox' claims are corrected.
A session that materialized its workspace-write grant and then switched to read-only (or crashed and resumed under read-only) kept a writable workspace for the server lifetime: the standing orphan-SID ACE survived the downgrade and list I still carried the orphan, so the write-restricted pass-2 check granted it. List I is now [logon SID, EVERYONE] only — the standing ACE stays inert under read-only while the unrevoked ACE keeps the re-upgrade free (map hit, no re-propagation). Pinned by the runner's real-token mode-downgrade regression (standing ACE denied under read-only, effective again on re-upgrade), the acl-session mode-switch cycle (nothing under read-only, one materialization on upgrade, no revoke on downgrade), and ConstrainedLanguage pins in both modes.
interrupt_agent(agent_id) passes the calling agent as the ancestor
authority for ctx.subagents.interrupt(); the service verifies live
registry identity and recorded lineage, so a direct child or deeper
descendant stops with the same generic parameter while send_message keeps
its exact-direct-parent authority.
Discovery: list_agents gains an optional scope. descendants walks the new
SubagentService.listDescendants() — one lineage trace flattened in stable
pre-order across ordinary and one-shot intermediates, each entry carrying
its verified parentId and depth — and every status now comes from the
live Agent registry (running/idle/complete).

The composer's single primary action now stops a running continuable
child: Session.cancel() routes a continuable address through
subagent.interrupt (ordinary sessions keep session.cancel; one-shot
addresses stay uncancellable), and InputBar switches the same Send button
to Stop while a continuable child runs. A running parent-offline child
keeps the default composer with disabled input so that Stop stays
reachable; the read-only takeover returns once it stops.
Refs #1535
The continuable-subagent core-data page and the continuation lifecycle
Agent Note claimed no public subagent cancellation existed; interrupt()
is now that one public stop. Both pages and their Chinese counterparts
state the shipped contract and link the owning interrupt note.

A browserless keyless-replay e2e boots the shipped web composition, holds
a continuable child's turn open with a replay hang entry, queues a
follow-up and interrupts over plain HTTP, and proves from the real
session state that the turn aborted, the follow-up parked without a new
turn, and a waking send resumed the preserved FIFO order.
Refs #1535
ctx.subagents.interrupt() stops one live continuable child's current turn
via Agent.cancel(cause, { keepInbox: true }) under either a human durable
parent address or an exact live ancestor Agent. Fire-and-return: admission
is synchronous, quiescence is not awaited. Pending inbox work, the
Activation, and published descendants are preserved; only a later waking
send resumes the parked FIFO queue. Absent, one-shot, and disposing
targets are accepted no-ops.
The new Host RPC subagent.interrupt calls only that primitive with user
authority — no catalog, history, persistence, or parent-registry lookup —
so a live child stays stoppable while its parent Agent is offline.
