Mohamed Boudra 91dca5702b Connect saved hosts and delegate agents across daemons (#7370)
* feat(hosts): connect to saved hosts through a daemon

* fix(hosts): validate safe targets and verify encrypted relay routes

* test(hosts): include relay coverage in existing CI contracts

* fix(cli): preserve validated addresses in daemon command hints

* fix(hosts): share daemon links across isolated routed sessions

Multiplex logical sessions over the monitored daemon connection and wrap original binary bytes in routing headers. Admit channels under their authenticated parent and current grants; preserve scoped delivery and physical send completion.

* fix(hosts): bound encrypted overload and initial acquisition

Check encrypted wire capacity before the async channel converts a resource limit into a physical connection error. Bound initial routed acquisition with the existing client timeout, then enable reconnect after admission.

* fix(hosts): keep compact row actions clear of host labels

Give compact connected-host rows separate text and action widths so long names and producer labels cannot compete with primary controls.

* refactor(hosts): remove management settings UI from phase one

Keep connected-host management in the CLI and shared SDK while preserving app saved connections and plugin access.

* test(hosts): control physical write backpressure across platforms

Hold real TCP writes until assertions finish instead of assuming a paused receiver exhausts every platform receive buffer. Preserve physical send settlement, byte identity, capacity and sibling checks.

* refactor(hosts): use the ordinary client contract over channel transports

Keep queuing, permission codes and reconnection independent of transport selection. Track submitted request outcomes generically while retaining connection error codes and structured causes.

* test(e2e): keep transient developer toasts from stalling checks

Concurrent locator handlers can wait for a dismiss button another handler removed. Dismiss existing toast DOM at document lifetime, including its open shadow root, without intercepting app actions.

* Create, prompt, and monitor agents across connected hosts (#7507)

* feat(hosts): delegate agents across connected hosts

Resolve MCP host operations through in-process commands for self and the existing routed client transport for other destinations. Keep ordinary parent labels, app sessions and idle finish notifications.

* test(app): normalize subagent fixtures through snapshots

* docs(protocol): clarify same-host parent labels

* fix(hosts): resolve subagents through destination sessions

A child address identifies its destination regardless of the connection used. Reuse the existing host candidate selection for discovered routes and direct connections, and keep navigation and row actions independent of the parent transport.

* fix(hosts): keep routed destinations distinct during discovery

A routed candidate names only the origin daemon. Match it within the named destination profile so two destinations discovered through the same origin retain separate identities and connections, including existing saved routes.

* feat(hosts): prompt and query agents on selected hosts

Extend the existing MCP host operation boundary with prompt, status, activity and list operations. Local calls retain their handlers and notification owner; selected destinations use ordinary client RPCs and the existing idle finish wait.

* test(e2e): preserve toast coverage with CSS hiding

* docs(hosts): translate connected host references

559c0200e0 Reuse workspace and subagent lists while replies stream (#7342)
* perf(app): skip workspace agent visibility rebuild on stream ticks

The workspace screen derived agent visibility on every session-store
update: it copied every agent and agent detail into a new Map, walked
all agents, and allocated two Sets, then compared them. Stream ticks
update the store but leave the agent maps untouched, so this was pure
waste at stream rate.

createWorkspaceAgentVisibilitySelector returns the previous result until
session.agents or session.agentDetails changes, and keeps it when a
recompute yields the same sets. Parent lookups read the two maps
directly instead of merging them.

Fixes #4817

* perf(app): skip subagent row rebuild on stream ticks

Every mounted agent panel selected its subagent rows by walking all
session agents, allocating rows, sorting, and deep-comparing on every
session-store update, including every stream tick.

createSubagentsForParentSelector returns the previous rows until
session.agents changes, and keeps them when a recompute yields equal
rows. The hook rebuilds the selector when the parent or the pending
archive ids change.

Mohamed Boudra efd6023b90 Restore live sessions immediately after app resume (#4160)
* perf(app): restore live sessions immediately after resume

Foregrounding now reconnects every host without waiting for scheduled backoff, while cached turns, timelines, agents, and workspaces remain internally consistent until authoritative catch-up arrives. Replica persistence is keyed and incremental so ordinary updates avoid whole-directory serialization.

* fix(app): preserve turn ownership through session updates

Stream turn closure now wakes queued-message delivery, while same-turn snapshots retain local cancellation state. Offline liveness remains visible until an authoritative close arrives.

* fix(app): preserve pending chat cache writes and trim resume refactor

Directory baseline replacement must preserve independently accepted timeline changes until the deferred flush. Keep the reconnect and persistence fixes while removing the session-data facade and broad read-hook migration.

* fix(app): initialize reconnect policy from current app state

Initialize visibility before host bootstrap so a background mount cannot leave reconnect enabled. Seed sidebar fixtures through the workspace owner so cache hydration preserves their rows.

* test(app): verify submission settlement across reconnect

Keep submission acknowledgement separate from turn liveness: disconnect preserves the running turn until authoritative catch-up. Wait for confirmed running chrome before exercising queued cancellation so the alternate-send shortcut cannot race turn startup.

* docs: remove cache implementation recap

Mohamed Boudra f4b209be4d Preserve nested subagent ownership (#4321)
* fix(subagents): preserve recursive provider ownership

Provider events retained enough lineage to identify nested work, but the canonical descriptor discarded the direct owner. Preserve that relationship at ingestion so child timelines and hierarchy remain attached to the process that emitted them, including after history replay.

* test(e2e): clarify nested ownership journey

* test(e2e): separate nested ownership actions

* fix(subagents): retain nested ownership across replay

Wait and interaction events can reference descendants without spawning them. Preserve the original spawning owner and route persisted background notifications through that same relationship after history reload.

* test(subagents): hide provider turn plumbing

* fix(subagents): scope nested tracks to their host

Plugin-provided icons are host-specific. Carry the panel host through nested child tracks so the rebased ownership UI resolves the same provider presentation as its parent.

* fix(workspaces): preserve launched terminal focus

Mohamed Boudra 75bbca4a1b Archive finished subagents across the whole track (#3368)
* feat(app): archive finished subagents together

Mohamed Boudra 8021d2b6c9 Keep agent timelines stable from submission through resume (#2718)
* Reapply: Stop completed turns from appearing stuck (#2484)

* Reapply: Keep older chat history and image previews stable (#2490)

* Lock timeline layout stability with user-driven specs

Two reds reproduce the reported jank:
- new agent, first prompt: the row paints at top=100 then jumps to 144 through
  authoritative hydration, because the draft tab and the agent panel each render
  their own AgentStreamView for the same logical row.
- long loaded timeline, submit: scrollHeight collapses 10793 -> 9111 mid-turn,
  because splitOrderedTail reclassifies measured rows into the virtualized segment
  where the virtualizer falls back to estimateStreamItemHeight.

Also restores centered timeline rows: the pagination anchor wrapper introduced in
#2490 was a plain block div, which broke alignSelf: center.

* Measure the turn footer blink from when the footer appears

Bounding the window at the prompt row conflated two things: the footer arriving a
frame after the row, and the footer leaving the layout and coming back. Bounded from
the footer's first frame, the blink still reproduces, so the footer-ownership race is
real rather than a sampling artifact.

* Rename the shadowed prompt row binding in the frame recorder

* fix(desktop): allow concurrent worktree dev instances

Desktop terminals can inherit another instance's profile path and debugging flags. Scope the profile to the current dev root and select an available debugging port so instances do not share global runtime state.

* fix(desktop): expose development providers in dev builds

Desktop-managed daemons inherited no Paseo runtime mode, so dev builds constructed the production provider registry. Mark unpackaged internal launches as development while continuing to force packaged launches to production.

* fix(timeline): stabilize optimistic turn layout

Keep initial history loading dormant until user intent and preserve active-turn layout across delayed transport updates. Add painted-frame coverage for optimistic timeline transitions.

* fix(timeline): preserve optimistic prompts through hydration

Canonical replacement relied on a transport submission record that can settle before a provider echoes the user row. Keep presentation continuity owned by the unreconciled row while destructive history replacement remains governed by active transactions.

* fix(timeline): make submitted prompts canonical

Submission settlement previously depended on status updates that could arrive after the optimistic row. Persist every accepted prompt in the canonical timeline and keep the footer active until RPC and canonical acknowledgement converge.

* fix(timeline): stop older history pages repeating entries

Backward pagination counted source sequence rows, so page boundaries inside a merged projected item could return that item repeatedly. Count projected entries and advance from their display anchors instead, with server and browser regressions covering the contract.

* fix(timeline): resume agents from the latest history

Use a bounded tail probe on resume so long background runs appear atomically instead of replaying every missed page. Preserve unchanged views, reconcile local/live rows, and keep skipped history reachable through backward pagination.

* fix(timeline): reconcile turn state after missed updates

Turn completion events can be missed while an agent timeline is unsubscribed, leaving footer activity stale even after the directory reports idle. Reconcile the single-owned turn lifecycle from authoritative resume snapshots while preserving newer live evidence.

* test(timeline): cover running state across refresh

Protect the hydration boundary where directory state must restore consistent tab, composer, and footer activity. Expose the running indicator semantically so the regression checks user-visible state instead of spinner implementation details.

* fix(timeline): keep history loading geometry stable

Reserve a fixed history-start gutter regardless of pagination state so showing or hiding the loader cannot shift timeline content.

* fix(timeline): keep turn activity coherent

Derive footer, tab, and composer activity from one lifecycle and submission projection. Idle directory transitions now request an authoritative resume so missed terminal events converge without treating directory delivery order as turn authority.

* fix(tests): align checks with runtime boundaries

* fix(desktop): stop dev app surviving its terminal

Electron was detached from the desktop runner, allowing it to outlive a stopped workspace terminal with broken output pipes and retain the single-instance lock. Keep Electron owned by the runner and preserve explicit process-group cleanup for detached child trees.

* fix(timeline): preserve activity through turn handoff

Correlate lifecycle events and snapshots with daemon-owned turn identity, and keep optimistic submissions active until their canonical row arrives. This prevents stale updates and RPC timing from exposing a false idle state.

* refactor(timeline): remove submission timing state

* fix(timeline): restore prompt identity on resume

* fix(timeline): exclude attachments from canonical prompt text

Structured provider prompts can include hidden history attachments before the user's text. Persist only plain prompt blocks so authoritative user messages match what the composer displayed while provider input remains unchanged.

* refactor(agent): remove unused pending-run message identity

* fix(desktop): let Chromium allocate the debugging port

* refactor(agent): remove impossible finalized-turn tracking

* fix(timeline): load history after keyboard scrolling

Treat observed upward displacement as user intent so keyboard and scrollbar navigation can wake dormant pagination.

* test(server): preserve accepted turn stream order

The manager-owned accepted turn boundary intentionally precedes coalesced output. Assert that lifecycle event explicitly while retaining the timeline-before-terminal ordering contract.

* test(app): scope sidebar fixtures by identity

Shared E2E daemon state may contain unrelated projects. Keep stale-route coverage tied to its named missing project and drag only the two rows seeded by the reorder spec.

* fix(timeline): gate prompt revisions by client capability

* fix(timeline): finalize canonical prompt delivery

Treat provider identity as a single stored-row transition so legacy clients receive one deliverable canonical prompt. Release identity-pending rows before later foreground output or the current terminal while preserving stale-turn isolation.

* fix(server): preserve legacy prompt pagination

* fix(timeline): keep assistant block identity stable

Assign canonical block IDs during live promotion so terminal finalization cannot remount image-bearing rows.

* fix(timeline): apply covered revisions during resume append

Run the exact canonical revision pass before overlapping resume pages append newer rows, while leaving cursor advancement to the incremental path.

* fix(server): preserve queued agent transitions

Project each queued live snapshot before awaiting stored metadata so later lifecycle state cannot overwrite an earlier transition.

* fix(server): snapshot queued agent updates

Capture each live agent payload before it enters the per-agent queue so shared nested state cannot change while an earlier storage read is pending.

* docs(app): date agent turn compatibility cleanup

* refactor(timeline): mint submitted prompt identity at acceptance

Canonical prompt rows now keep one immutable wire identity while provider identity remains internal for rewind translation. This removes the unreleased same-sequence revision and legacy projection contract.

* refactor(app): remove prompt revision reconciliation

Submitted prompt rows are immutable on the wire, so resume and live reducers no longer need to apply already-covered same-sequence updates.

* test(app): cover submitted prompt rewind roundtrip

* docs(timeline): describe immutable submitted prompt identity

Provider echoes now enrich daemon-internal identity only; wire rows keep their acceptance-time identity and rewind performs the provider translation.

* test(server): validate mock rewind targets

Reject unknown provider message IDs so app rewind coverage exercises wire-to-provider identity translation.

* fix(server): validate rewind before interrupting

* fix(server): omit rewind identity for daemon prompts

* test(app): guard rewind eligibility and rejection

* fix(server): preserve prompt identity across hydration

* refactor(timeline): remove stale revision remnants

* Revert "fix(server): preserve prompt identity across hydration"

This reverts commit 6adcf7e5b0.

* fix(timeline): settle missed submission acknowledgements

706ae3d9bb Read Claude subagents from the SDK task protocol (#2498)
* refactor(claude): derive subagents from the SDK task protocol

Claude Code announces subagent identity and lifecycle on the SDK stream
(task_started, task_updated, task_notification). Paseo consumed only
task_notification and reconstructed the rest from sidechain frames, in two
independent derivations that had drifted apart.

Both paths now translate into one small observation vocabulary and fold it
with one function, so identity and status are derived once. The fold is
stateless: the task protocol is edge-triggered and the store's sticky merge
already accumulates.

- Replay links a subagent through the agent-<id>.meta.json sidecar, which
  carries the same Task tool_use id the live stream keys on. The agentId
  text scrape stays as a fallback for sessions recorded without it.
- The sidechain tracker keeps mapping frames to timeline items but no longer
  owns the descriptor when the task protocol is active, detected from the
  session rather than from a version string.
- Adds replay coverage, which did not exist.

Subagent ids are unchanged, so no protocol, store, or client change.

* fix(claude): keep non-subagent tasks out of the track, open the child timeline with its prompt

Backgrounded shell commands announce as task_started with a tool_use_id but
task_type local_bash and no subagent_type, so filtering on the id alone put
`sleep 20` in the subagents track. Discriminate on task_type, falling back to
subagent_type for releases that predate it.

task_started also carries the prompt. Emitting it as the child's first timeline
item means the pane no longer opens mid-conversation, and matches replay, where
the sidechain transcript already begins with the prompt.

Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

* fix(claude): drop status for tasks that were never declared as subagents

task_notification also fires for backgrounded shell commands and carries a
tool_use_id. Routing status off that id readmitted exactly what the declaration
filter rejected, as a descriptor with a status and no identity — rendered in the
track as a nameless "Loading..." row.

Status now routes only through the task_id map populated at declaration.

Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

* fix(app): name a subagent row after its task, not its type

The descriptor carries the subagent type in title and the task in description.
The client collapsed them and rendered only the type, so every child in a
fan-out read "general-purpose". The task is what tells siblings apart, so it
names the row and the type moves to the muted secondary line, which the track
computed but never drew.

Providers that report no task keep the previous behavior.

Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

* fix(claude): label the parent's Task card from the subagent declaration

A backgrounded Task subagent emits no frames carrying parent_tool_use_id, so
the sidechain tracker never runs for one and never supplies the sub_agent
detail. Its card in the parent transcript rendered as a bare "Task".

The declaration already carries the type and the task, so the card is built
from it. For a foreground subagent the tracker still emits the same card
enriched with the child's action log; the two collapse on the shared tool-call
id, so that case is unchanged.

* feat(subagents): surface a subagent's model, effort, and cost

Adds model, effort and usage to the provider subagent descriptor, populated
from observations the child itself reports.

- model: read per assistant frame, live and on replay. Never snapshotted, since
  a provider can swap models mid-flight on overload or refusal fallback, and
  never inherited from the parent.
- effort: replay only. The SDK's assistant message does not carry it and it can
  be silently downgraded for the chosen model, so a live value would be a guess.
- usage: task_progress reports tokens and tool count once per tool use, and
  task_notification reports the terminal totals. This matters most for
  backgrounded subagents, which emit no sidechain frames and would otherwise
  show no sign of activity at all.

Status becomes optional on the upsert event: a report that only carries a model
or a cost says nothing about whether the child is still running, and must not
revert a finished one. Usage merges rather than replaces, because duration only
arrives at the end.

Fields are optional on the wire, so an older daemon simply omits them and the
client renders nothing rather than substituting the parent's settings.

Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

* feat(claude): read subagent effort from hooks

Effort appears nowhere on the SDK message stream — verified by scanning every
message type at depth — and the level Paseo requests is not necessarily the one
that runs, since a model that does not support it is silently downgraded.

Hooks are the source. Every hook input carries agent_id and effort.level, the
active level for that turn after any downgrade, and agent_id is the same id
task_started calls task_id, so it routes through the table already built at
declaration. PreToolUse, PostToolUse and SubagentStop are registered purely to
observe; they record what they see and always return empty, so they cannot
affect tool execution or turn control.

Paseo's hooks merge with any the user configured rather than replacing them:
extraClaudeOptions is spread after the base options, so assigning would have
silently stopped effort being observed for anyone with their own hooks.

Verified end to end through ClaudeAgentClient against a real session: a
subagent descriptor now carries model, effort and usage together.

* feat(subagents): show a subagent's runtime facts in its pane, and its cost on replay

The track row carried model, effort and cost; the pane carried none of it, so
opening a subagent showed only its task.

The pane gets a header strip rather than a longer tab subtitle: the subtitle
feeds the width-constrained tab strip, whose job is to name the task. Duration
appears in the pane, which has room, and stays out of the dense row.

Replay had no usage source, so a reopened agent lost its subagents' token and
tool counts permanently — descriptors are in-memory and cleared when an agent
closes. Usage is now derived from the child's own transcript, matching the live
producer exactly: total tokens are the four counters summed on the last
assistant turn (a context reading, not a cumulative sum, which would multiply
the cached prefix by the turn count), and tool uses are tool_use blocks across
assistant entries. Duration is an approximation — the transcript's first entry
is written after the task starts — and is the one field replay cannot match.

Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

* docs(claude): record the task protocol's undocumented wire facts

The subagent sources depend on Claude Code internals the SDK types do not
explain: which announced tasks are subagents, why a status for an undeclared
task is dropped, why task ids outlive a turn, why effort is only reachable
through hooks, and why a replayed session must skip its grandchildren.

Mohamed BoudraandOmer 66445adc07 Show provider subagents in the subagents track (#2013)
* Add provider-owned subagent stream contract

* OpenCode provider: detect child sessions, attach adopted children to the hosting server, synthesize external turns

- Emit internal provider_child_session_detected / provider_session_deleted stream events from the global event stream (before the no-active-turn gate), including BFS hydration of existing descendants on subscribe
- Track child sessions in a registry mapping child session id -> hosting server url; resumeSession attaches via acquireExisting() so adopted children share the parent's server generation and keep receiving live events
- Synthesize external turns for adopted (externally driven) sessions so timeline, tool calls, and permission requests stream without a Paseo-initiated prompt
- Honor launchContext.env in resumeSession (acquireDedicated parity with createSession)
- Stop folding child tool parts into the parent's sub_agent action log; the parent row stays as a pointer

Mohamed Boudra 3eda7dd15b fix(app): subagents track display + archive flicker
- Bucket finished subagents as `done` instead of `attention`; drop
  "needs attention" segment from the section header — subagents are
  transient and don't carry an unread state worth surfacing.
- Gate the subagents selector on the existing pending-archive query so
  optimistic archives survive authoritative agent snapshots that wipe
  the local `archivedAt`. Last subagent archived now cleanly hides the
  whole track via the existing empty-rows guard.

Mohamed Boudra c097678cdf Surface paseo subagents in a collapsible section above the composer (#532)
* Surface paseo subagents in a collapsible section above the composer

Subagents no longer auto-open as tabs. Each parent agent's pane shows
a compact tab attached to the top of the composer, listing its direct
children with name and status; clicking a row opens or focuses the
subagent's tab. The section is provider-neutral so Claude Code Task
and Codex subagent sources can feed the same UI later. Reconciliation
now separates pruning (`activeAgentIds`) from auto-opening
(`autoOpenAgentIds`) so manually opened subagent tabs survive.

* Tighten subagents composer code from review

Collapse duplicate helper in workspace reconciliation, swap a hand-rolled
shallow comparator for fast-deep-equal (matching repo convention), drop
an unused React default import and a single-use formatCount helper, and
extract a shared PaneOverrides type in the agent-panel test.

* Fix oxlint failures in subagents code

Switch type aliases to interfaces, hoist inline JSX styles/handlers in
SubagentsSection to satisfy react-perf rules, and lift the test
makeAgent helpers onto AGENT_DEFAULTS so their cyclomatic complexity
drops below the configured cap.

* Add missing unistyles mock exports after rebase

After rebasing onto main, SubagentsSection now imports both
useUnistyles and (transitively, via WorkspaceTabIcon) withUnistyles.
Two test mocks needed updating to expose them.

Test drift fix: the implementation contract is correct; the local
react-native-unistyles mocks were stale.

* Tuck subagents tab under the composer

Subagents tab now grows visually from beneath the composer's rounded
top edge: the surface overlaps the composer by the corner radius so
the rounded curve nests into the tab. Composer's top padding is
removed so the tab sits flush against the input box with no
click-dead gutter. The tab is full-width in both states, the header
label drops the medium weight to follow design-system §3 (content
text inside a surface is normal), and hover covers the entire
visible tab when collapsed but stays scoped to the header row when
expanded.

* Decouple subagent close-tab from archive

Closing a subagent's tab no longer archives the agent — the tab is
removed from the per-client layout, the agent stays in the parent's
track until explicitly archived. Track rows gain an archive button (X)
to make the lifecycle gesture explicit. AgentManager.archiveAgent now
cascades to children carrying the paseo.parent-agent-id label so
subagent fleets don't outlive their orchestrator.

Trade-offs documented in docs/agent-lifecycle.md, including the known
limitation that handoff agents launched via the same MCP path get
cascade-archived alongside true subagents until a richer relation
model lands.

* Stabilize subagent archive button hover

Apply the sidebar workspace row pattern to fix two issues with the
new archive button: the row no longer drops hover when the pointer
moves onto the button, and the button slot reserves layout space
when invisible so adding/removing it doesn't shift the row.

The wrapper View tracks hover via onPointerEnter/onPointerLeave
(workspace rows do the same), and the slot stays mounted with
opacity 0 + pointerEvents="none" when the button is hidden. Also
swap the X icon for the Archive icon to match the gesture's intent.

* Match design language for subagent archive button

Hover state now changes the icon color from foregroundMuted to
foreground, matching the project-row trailing-action pattern in
sidebar-workspace-list.tsx. Drops the surface3 background hover
that didn't match the design language.

Adds a tooltip ("Archive subagent") on the trigger using the
canonical Tooltip + TooltipTrigger asChild pattern. Disabled when
the slot is hidden so it never appears unbidden.

* Slot subagents into one module + harden cascade

Reshape the subagents-in-composer feature so it lives behind one
module and integrates at a few explicit sites instead of being
smeared across generic files.

- Extract `PARENT_AGENT_ID_LABEL` to `packages/server/src/shared/agent-labels.ts`. Sweeps 16 literal sites across server, client, CLI, and tests.
- `packages/app/src/subagents/` is now a deep module: `index.ts` is the only React entry (`SubagentsSection`, `useArchiveSubagent`, `useSubagentsForParent`, `selectSubagentsForParent`, `resolveCloseAgentTabPolicy`, `shouldAutoOpenAgentTab`); `policies.ts` is a second designed entry for non-RN data consumers. Internal files renamed (`section.tsx`, `select.ts`, `close-tab-policy.ts`, `auto-open-tab-policy.ts`, `use-archive-subagent.ts`).
- Move the 22-line subagent archive flow out of `agent-panel.tsx` into `useArchiveSubagent`. Agent-panel becomes a one-line consumer.
- Move the close-tab subagent branch out of `workspace-screen.tsx` into `resolveCloseAgentTabPolicy` (discriminated union).
- Move the auto-open exclusion rule out of `workspace-agent-visibility.ts` into `shouldAutoOpenAgentTab`.
- Theme chevrons in `section.tsx` via `withUnistyles`; drop the forbidden `useUnistyles()` call from the hot path.

Server-side cascade hardening:

- Single write path: extract `markRecordArchived` and route both `archiveAgent` and the off-memory cascade branch through it. Off-memory cascaded children now notify subscribers (previously silent).
- Cascade no longer swallows child failures with `try/catch warn`. Failures propagate.
- Cascade test extended from 1 weak assertion to 5 contract tests: full archive shape (archivedAt, normalized lastStatus, requiresAttention=false), running child runtime stop, off-memory branch, subscriber notification for in-memory and off-memory children, partial-failure surfacing.

Net diff vs the start of this PR: -1037 / +444 lines. The feature now slots into the repo at four explicit sites: `agent-panel.tsx` (3 imports + a hook + the section), `workspace-screen.tsx` (one policy import), `workspace-agent-visibility.ts` (one predicate import), and `agent-manager.ts` (the cascade plus the shared label constant).
