A delegated in-process child now acts only within the sandbox scope fixed
at delegation: captureDelegatedPolicyOverrides still snapshots the parent's
explicit sandbox override but pins the child approval policy to 'never'
(instead of inheriting the parent's), so every child ask — sandbox_permissions
escalations included — is rejected deterministically by ApprovalService
before any answerer, with the audit pair still logged. Every in-process
child additionally receives the scoped subagent:delegation runtime-context
statement telling it to report a scope limitation instead of retrying.
Supersedes the approval half of the policy-inheritance decision (new Agent
Note cross-linked from both prior notes and the approval-seam Q&A); refreshed
child snapshot fixtures carry the pinned event, and
subagent-published-run-failure now persists a one-event child log.
The section knows no namespace: it declares `settings.plugin.item` and
renders whatever cards were registered into it, so a plugin that ships a
browser half owns its card and its controls. The three cards here cover the
host-plane sections this deployment exposes.
A field shows its effective value and, when the raw user layer carries it, an
override badge and a reset that clears it back to the composition layer.
Controls commit on blur and Enter rather than per keystroke, which would burn
namespace revisions and race its own reads. The search key is the one value
that never rides a response: the card reports only whether one is configured
and writes it through the credentials domain, addressed by the reference the
section names.
A card renders nothing while its namespace is unavailable — a deployment that
does not compose the owning plugin should show no trace of it rather than a
disabled card the user cannot act on.
Release the Web Stream reader after either completion or cancellation. Strengthen the oversized-file test so a regression that downloads content before applying the stat bound fails directly.
The windows-native job has been red since #1990 put the sandbox-windows-acl sources into the Windows 100%-per-file denominator without tests carrying them, and #1543 dropped the authoring.ts V8 ignore for the POSIX-only owner-execute branch. Non-blocking at merge time, the red state has propagated to every later pull request.
Cover every in-process ACL-sandbox failure branch with stub-based failure-path suites (ffi/acl/token/spawn/index), following the package's existing failure-paths pattern; the package now measures 100% per file under the Windows denominator. Exclude only the runner entry from the win32 denominator: it executes exclusively as a spawned child outside the instrumented run, and its behavior is pinned end-to-end by the runner suite. Restore the authoring.ts narrow V8 ignore and add one for the dispose token guard whose absent-token arm is lifecycle-unreachable. Update the dual-lane Agent Note with the denominator composition.
A form needs two things the snapshot did not carry. The `user` layer tells it
which fields the user overrode — presence, not value equality, because an
override equal to the composition default is still an override — and `base`
is what a cleared field reverts to. `unset` is that clear, sharing `set`'s
queue, revision fence, and rejected-write recovery through one write path.
Registration alone still never crosses the boundary: the three host-plane
sections the plugin configuration page edits join the explicit allowlist, and
the assertion that pins the served set is what catches a namespace silently
dropping out of the page.
The provider now takes a thunk rather than a value: it projects the
authoritative section per search, so a stored endpoint, model, or key
reference reaches the next call without re-registering the provider — which
would make the seam's provider selection observable as a flicker.
apiKey already carries role('secret'), so the section is safe to describe:
the literal never rides a response in any layer and a configuration surface
learns only that a key is set.
The section is a strict subset of the plugin config: `agents` is consumed
once when the service starts, so a stored change there could only look like
it had an effect. The cap resolves through a getter over the settings source,
which the scheduler destructures at the start of each tool group, so a
committed change bounds the next group without disturbing the one in flight.
`resolveMaxParallelToolCalls` becomes the section validator, refusing a value
at the write instead of at that group.
The deferred-resume effect-shape assertion now allows the one plugin effect
the optional settings wiring adds at the fiber's own level; a resumed agent
joining it there is still the regression it pins.
The 导出 button fetches GET /api/session.export and saves the ZIP (root
artifact plus subagent descendants). The plugin exposes exportLog through
the view's inject face, resolves the tab label through the locale service,
and disables the button while in flight; fixture mode answers 404 so the
error bar explains the gap.
Streams one ZIP of the root session artifact plus each subagent descendant
verbatim (the persistence readRaw bytes) from GET /api/session.export as a
host-only download — no wire envelope, absent from IApiClient. The downloads
domain owns the query schema, the fetch handler answers the GET alongside the
SSE routes, and compression runs on the host with fflate's streaming Zip API.
The persistence contract gains a concrete readRaw default (undefined for
backends without a per-session artifact) and the JSONL backend overrides it
with the decode of its physical zstd frames, so a consumer can read the
stored artifact text verbatim — the session-log export depends on it.
Enable serial-windows to execute the complete check:ci on the in-house
self-hosted Windows pool instead of the disabled hosted windows-2025
lane. Point the job at [self-hosted, dsh-win-ci, windows] and wire it
into all-checks-passed so it gates pull requests.
The Wine-emulated windows job remains the required win32 signal for
PRs that cannot reach the self-hosted pool; this lane adds a real
native-Windows run where one is available.
Tool and prompt-section visibility is inherited along dsh-scope's parent
chain, and an agent's scope key is minted with no parent. Per-session agent
presets moved every model-facing row onto the agent plane and made
AgentPresets.mount() the one thing that binds that link, from the api-proxy's
session create, resume, and fork paths. The two in-process subagent drivers
installed only the per-child persona and tool filter, so a child's scope chain
had length one and its registry view resolved the global layer alone — which
is empty wherever a preset roster is composed. One-shot children reached the
model with no tools, continuable ones with only the host-plane `report`, and
neither carried its parent's persona, workspace context, or skill catalog.
AgentPresets.composeFrom() joins one agent to the standing composition another
already runs on. It is a bind, not a mount: the child gets its parent's exact
generation, so a composition edited since the parent started cannot fork it
onto another one, and it is synchronous, which is what lets a child creation
window use it. applyChildComposition() now takes the parent and performs the
join first, making a child composed without it unrepresentable at the call
sites. childSessionMeta() records the joined id so a cold read rebuilds the
composition the child actually ran under.
The audit that followed found two api-proxy readers on the wrong authority:
presenterScopeFor() and the live-agent branch of assertPresetUnchanged() both
read header.agentPreset, which goes stale the moment a blank session switches
preset. A switched session's cold transcript resolved presenters in the older
composition's layer and silently degraded to generic cards, and the gateway
refused to adopt a live session under the preset it actually runs while
accepting the one it left. Both now resolve through resolveSessionPreset(),
matching the resume branch fifteen lines above. The owning architecture Agent
Note carried the stale claim that the header records what a session runs; it
is corrected to name the header/log pair and its three readers.
