* 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.

* 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.

* 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.

* 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.

* 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.

* 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.

Route live OMP custom messages through the existing system-notice mapper so background notices render as task notifications while advisor, hidden, and ordinary custom-message behavior stays intact.
* Accept OMP session state without thinkingLevel
Models whose reasoning effort is encoded in the model ID (e.g.
cursor-grok-4.5-high-fast) are marked reasoning: false by OMP, which
omits thinkingLevel from get_state. The required schema field made
session creation throw a ZodError. Make it optional and resolve the
thinking option to null when absent.
* Render OMP advisor messages as blocks
Pi and OMP share only the JSONL child-process transport while retaining provider-owned launch, RPC, runtime, session, history, and permission behavior. Removes captured fixtures in favor of typed harnesses and real-provider coverage.
Closes#2006Closes#2060
* fix(pi): complete locally handled prompts
Slash commands the Pi CLI handles without starting a model turn previously
left the Paseo turn hanging until interrupt. Parse the optional
agentInvoked correlation from prompt acknowledgements, surface
command_output/notify output as timeline content, and complete the turn
locally when no agent turn will start. Older Pi binaries without the
correlation are detected via a getState compatibility probe.
* review: guard command output without an active turn, simplify delegates
- Drop late-arriving command_output when no turn is active instead of
emitting an orphaned timeline item with turnId undefined
- Remove redundant 'text' in event check (type is already narrowed)
- Inline recordNoTurnNotification delegate
* refactor(pi): consolidate local prompt state
