* feat(plugins): implement Host data API write RPCs (CreateTask/UpdateTask/CreateComment)
The api_write manifest capability was a stored no-op. Wire the deferred
phase-2 write RPCs (ADR 0043) so closed-loop plugins (Sentry->task,
Slack slash-command task creation, refactor fan-out) can create and
update tasks and post comments.
- SDK: Host.Tasks() gains Create/Update; new Host.Comments() writer;
CreateTaskInput/UpdateTaskInput/Comment DTOs (pkg/pluginsdk).
- Gating: api_write:tasks gates Create/UpdateTask, api_write:comments
gates CreateComment; undeclared -> gRPC PermissionDenied, per-method
and independent of the read caps on the same resource.
- Writes route through the first-party service layer (task service for
tasks, office service for comments) via backendapp adapters, never a
repository -- so task.*/comment-created events fire and WS updates.
Server stamps source="plugin:<id>"; CreateTask resolves workspace/
workflow defaults and best-effort honors start_agent; UpdateTask uses
a conservative title/description/state/workflow_step_id mask.
- Fixture plugins exercise a CreateTask+CreateComment round-trip;
in-process, real-broker wire, and subprocess tests cover the round-trip
and per-capability denial.
- Docs: spec, GRPC-CONTRACT, HOST-DATA-API.proto, proto comments moved
writes deferred -> implemented; ADR 0043 amended with the concrete
service-layer routing decision.

* feat(plugins): send a message to a task session via Host SendMessage (replaces CreateComment)
The office TaskComment write was the wrong primitive — it's an office/
dashboard construct, not a way to message the agent working a task, and
it only did anything under office reactivity. Replace the CreateComment
write RPC with SendMessage, which delivers a prompt to a task session
through the orchestrator's real delivery path (the same one message_task
uses).
- Proto: swap CreateComment/Comment for SendMessage(SendMessageRequest)
returns SendMessageResponse{session_id, status}; regenerated stubs.
- SDK: Host.Comments() removed; Host.Messages().Send(taskID, sessionID,
text) added (pairs with Messages().List), returning MessageDispatch.
- Gating: api_write:comments dropped; SendMessage gated api_write:messages
(independent of api_read:messages on the same accessor, like Tasks()).
- Delivery: a new pluginsTaskMessengerAdapter (backendapp) resolves the
target session (explicit id verified against the task, or the primary
session), records a user message stamped source="plugin:<id>", then
dispatches by state — running → queue; idle/completed → prompt (resume
if the agent process is gone); never-started → launch; failed dispatch
deletes the recorded message. Wired via SetWriteDeps (live-read).
- Tests: adapter state-machine unit tests (queue/start/prompt/resume/
delete-on-failure/belongs-to-task/no-primary/terminal); SDK, in-process
gating, wire, and subprocess round-trips updated to SendMessage.
- Docs: spec, GRPC-CONTRACT, HOST-DATA-API.proto, proto comments, and the
ADR 0043 amendment updated from comment-create to message-send.

* fix(plugins): address PR review — nil guards, detached contexts, state validation
Follow-up fixes from the #1970 review (Claude + CodeRabbit bots):
- grpcHostServer.CreateTask/UpdateTask/SendMessage: nil-guard the returned
value before toProto() so a custom/test Host returning (nil, nil) yields a
gRPC Internal error, not a server panic (matches GetTask's pattern).
- host.go: fix stale server doc comment (Comments()/CreateComment →
Messages()/SendMessage).
- startTaskBestEffort and the post-resume wait+retry now run on
context.WithoutCancel(ctx): the task/resume is already committed, so a
plugin's incoming deadline must not silently abort the launch/resume.
- pluginsTaskWriterAdapter.UpdateTask validates the state string against the
known task-state enum (excluding orchestrator-owned SCHEDULING) and returns
InvalidArgument, so a plugin typo can't forward a bogus state to the service.
- Tests: add the resume-wait-timeout path (message deleted so a retry can't
duplicate), and a dedicated pluginsTaskWriterAdapter test covering
source→metadata mapping and state validation (both adapters now depend on
narrow interfaces for testability).

* fix(plugins): launch start_agent asynchronously so CreateTask doesn't block
Review nit follow-up: startTaskBestEffort called StartTask synchronously, so
with the detached context the plugin's CreateTask RPC blocked on the
orchestrator's full inline launch path (office lookup, state update, workflow
step move, task fetch) with no bound — and the "asynchronous" comment was wrong.
Move the fire-and-forget into pluginsTaskStarterAdapter (backendapp, no goleak),
mirroring MCP's launchAutoStartTask: the launch runs in a goroutine on a
context.WithTimeout(context.WithoutCancel(ctx), AgentLaunchTimeout), and
StartTask returns immediately. The plugin host stays a simple synchronous call
(its taskStarter contract now documents "returns promptly, launches async").
Adds adapters_plugin_starter_test.go: launch invoked, returns before the launch
completes, detaches from a cancelled caller context, and swallows launch errors.

* docs(plugins): document write validation + SendMessage rollback; harden starter test cleanup
Addresses the final PR #1970 review nits:
- adapters_plugin_starter_test.go: register the block-channel release via
t.Cleanup (sync.Once-guarded) before the goroutine can block, per AGENTS.md.
- GRPC-CONTRACT.md: document CreateTask/UpdateTask validation + error rules
(title required, id required, NotFound on missing task, invalid-state reject).
- spec.md: document that a failed SendMessage dispatch deletes the recorded
message, plus the required-field/NotFound/terminal-session rules.
