Bounds plugin disk use: installing never removed the version it replaced, so
~/.kandev/plugins/<id>/ accumulated a full copy per install forever (4.2GB on
one machine, 3.74GB of it superseded versions). A plugin now keeps its active
version plus one rollback target, pruned only once the new version is
confirmed running.

Per-session events are published on a suffixed bus subject
("shell.output.<sessionId>") but stamped with the bare event-type constant
("shell.output"). The plugin deliverer subscribed with the manifest pattern and
then re-checked that pattern against event.Type, which made every suffixed
subject undeliverable: a 3-segment pattern matched the bus subscription but
failed the re-check on segment count, while a 2-segment pattern passed the
re-check but never subscribed to the 3-segment subject.
Carry the concrete publish subject on bus.Event (stamped in place by Publish in
both the memory and NATS implementations; the NATS receive side prefers the
delivering msg.Subject) and re-check the manifest pattern against it via a new
Event.EffectiveSubject helper that falls back to Type. The concrete subject is
also what plugins receive as pluginsdk.Event.EventType -- already documented in
the proto as "bus subject" -- so a plugin subscribed to "shell.output.*" can
read the session id off it.
Audited all 109 EventBus.Publish call sites: 17 subject families were affected;
office.run.event_appended, the office tree-hold subjects and the cross-plugin
plugin.<id>.<name> already stamped Type with the full subject. Three git.ws
sites in the orchestrator publish on git.ws.<sessionId> while stamping
events.GitEvent, so the subject there is not a suffixed form of its own type at
all -- left as-is, since the gateway routes off the subject and never reads
event.Type. Unsuffixed subjects publish with subject == type, so existing
2-segment subscriptions are unaffected, and the re-check still enforces manifest
segment-count strictness over the bus's looser NATS ">" semantics.
* 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.

* feat(plugins): add auth capability for plugin-provided OIDC/SAML login
Plugins can now authenticate a visitor against an external IdP (OIDC/SAML)
and contribute a login button to the pre-auth screen:
- new `auth` manifest capability + a capability-gated X-Kandev-Auth-Login
webhook-response directive; the host mints the kandev_session (ADR 0050),
the plugin never receives the raw token. Plugin-set Set-Cookie is dropped.
- auth.Service.AuthenticateExternal: existing-identity / link-by-email / JIT
member provisioning; refuses to auto-link to an admin; verified-email is
the plugin's contract.
- auth_providers manifest block + plugins.SSOProviders() populate the
anonymous boot payload (auth.ssoProviders); the login page renders a
"Continue with <provider>" button per provider.
- ADR 0050 + plugin-manifest / plugin-authoring / auth spec docs.

* docs: exclude publish_review_findings_kandev from public-docs coverage
The native code-review agent (#1957) added the publish_review_findings_kandev
MCP tool but did not update docs/public/coverage.json; that PR did not touch
docs/public so the path-filtered validator never ran. It's an internal review
reporting tool, not a user-facing feature, so record it as an exclusion.

* fix(plugins,auth): address review on SSO directive and JIT provisioning
- takeAuthLoginDirective strips every case variant of X-Kandev-Auth-Login and
rejects (403) when a plugin sends more than one, so no variant leaks to the
browser and login never uses a nondeterministically-picked assertion.
- provisionExternalUser rolls back the just-created user when the identity
insert fails (transient error or a lost UNIQUE(provider,subject) race) and
resolves to the winning identity, so no account is left without a login and
no email is reserved by an unusable row. Adds userstore.DeleteUser.
- auth spec: mark the login-page SSO buttons + provider discovery as landed.

* feat: add opt-in plugin auto-updater
Automatically update installed plugins in the background, off by default
and opt-in. Builds on the existing verified install pipeline — an
auto-update is just an automatic reinstall of a newer catalog package_url.
Two-tier toggle on Settings > Plugins: an instance-wide default (SQLite
plugin_settings) plus a per-plugin override (tri-state auto_update on the
plugin record, carried forward on upgrade). The AutoUpdatePoller
(~90-min cadence + a boot sweep) upgrades only plugins that are currently
active, opted in, and report update_available; disabled/errored plugins
stay on their installed version.
New endpoints: GET/PUT /api/plugins/settings and
PUT /api/plugins/:id/auto-update.

* fix(plugins): recheck auto-update eligibility at install and fix test mock
Address PR #1903 review feedback:
- Re-check each plugin's current status + effective opt-in immediately before
InstallFromURL (eligibleForAutoUpdate), closing the TOCTOU window between the
candidate snapshot / catalog fetch and the install so a plugin disabled or
opted out mid-sweep is never reinstalled and reactivated.
- Correct the marketplace spec to describe the real failure behavior (shared
with manual updates) instead of promising a version rollback the install
pipeline does not perform.
- Fix the frontend CI failure: the plugins page test mocked the whole
plugins-api module without the new settings/auto-update functions, so
useAutoUpdateSettings threw at mount.
- Add an aria-label to the per-plugin auto-update Switch and Reset control.
- Add a use-auto-update-settings hook test (load, failure, optimistic setDefault,
rollback) and an eligibleForAutoUpdate unit test.
