feat(server): deliver finished runs to plugins from an acknowledged cursor

[saphid]

Stacked on #16047 (and #15010). Review only the top 6 commits: d92c363.

Rebased 2026-10-10 onto #15010's current head (1fe8efd69a, on main 57b3780). The follow-up commits in this PR answer review-bot and review findings, each with a focused test; GPT-6.1 Sol (high) reviewed them in two rounds: SHIP. The plugin event cursor table moved from migration 060 to 062 after main's two new migrations, and RunFinalized.test.ts imports the ID allocator from @t3tools/provider-core, where main moved it. A new first commit makes the replay harness answer a runtime request only once its approval or question card is projected: a provider's request and its card can commit separately, and with this layer's extra work per commit the harness answered between them, leaving main's subagent approval cards "waiting". Clients already answer the card they show, so only the harness changes. Main moved the host process references into a HostProcess module (#17641), so the event feed test provides the process arguments through HostProcess.Arguments. GPT-6.1 Sol (high) reviewed this port: SHIP. Captures below were taken at the revisions they name. At this head (d92c363683) these pass: focused tests (11 files, 138 tests), typecheck (t3, @t3tools/client-runtime, @t3tools/contracts), lint and fmt on the changed files, knip.

Problem

A plugin cannot react to the one thing people most often want it for: "a turn finished". There is no durable OV2 record that a run and its follow-up work are done. thread.settled is the sidebar's parking state, and the terminal run.updated lands before the checkpoint capture and workspace refresh. A plugin that keyed off either would fire early, twice, or not at all after a restart. There is also no path from the event log to a plugin process, so the plugin host from the previous stacked PR has nothing that actually launches a plugin.

This PR adds both halves of one concern: plugins receive run lifecycle events at least once, in order, from an acknowledged cursor that survives restarts. Nothing user-visible changes in the web, desktop or mobile UI.

Why this qualifies

This is the proposal route in CONTRIBUTING. It needs two approvals, and no maintainer has agreed to either yet:

• OV2 owner: the new run.finalized / run.finalization-failed thread events in the orchestration contract (on #6837 or a new Ideas post). Its only consumer today is plugin events, which is why it ships in this PR instead of on its own.
• #6837 (lifecycle hooks for extensions), on top of the plugin-system approval the previous PR needs on #6714 / [Feature]: Pi-style extension API for lifecycle hooks, UI contributions, and settings #6837.

It stacks on the plugin host PR (supervised child processes + catalogue + consent). If the answer is no, we close this and the plugin PRs above it. Previous PR in this stack: feat(server): run consented local plugins in supervised child processes (#16047).

Fix

Run finalization (OV2).

• Contracts: run.finalized { runId, outcome: completed | failed | interrupted | cancelled, checkpointId | null } and run.finalization-failed { runId, operation: capture-checkpoint | refresh-workspace | record-finalized } as thread events (and their JSON arms). Clients without this PR skip them as unknown events.
• Every newly finished run that was not rolled back records exactly one of the two, once, under one deterministic event id. A run that queued a checkpoint capture records run.finalized from RunFinalizationService after capture and workspace refresh succeed. When the effect worker gives up on its last attempt, the failure record commits in the same transaction that fails the outbox row; a cancelled capture records the failure in the cancelling commit; an interrupted capture is replayed after restart, never recorded as a failure.
• Every other terminal path (provider failure, stop, start failure, restart recovery, thread deletion) is finalized by one commit-time rule in EventSink, so a new terminal path needs no extra wiring. Thread activity, thread.settled and the relay are unchanged.

Plugin events.

• A plugin declares "capabilities": ["events"] with "proposedApi": true and registers context.proposed.onEvent(handler). A server without this PR refuses the plugin instead of running it without delivery.
• Projection (pluginEvents.ts): only those two event types, each with deliveryId (stable dedupe key), sequence, occurredAt, environmentId, threadId, runId, the thread's projectId and title (≤200 chars, null if the thread was deleted), and outcome or operation. No message text, no provider ids.
• Delivery (PluginEventFeed.ts, migration 058 plugin_event_cursors): one cursor per installation, started at the end of the log when the installation is enabled (no history backfill). The feed reads bounded pages from the durable event log and invokes the host-reserved t3.events handler through the plugin catalogue. The cursor moves only after the plugin acknowledges the page. EventSink commits only wake the feed through a sliding subscription, so orchestration never waits on a plugin.
• Failure handling: any failed page (handler error, timeout, crash, defect) is retried with backoff (2 s doubling to 1 min) and quarantined after 5 consecutive failures with the cursor unchanged. The existing plugins.resume clears quarantine; re-enable and restart retry from the cursor. A stored event the server cannot read (bad payload or bad identifiers) stops delivery in front of it, quarantined with 0 failures, until it is repaired and resumed; it is never skipped. Storage errors are never counted against the plugin. Disable stops delivery, enable continues from the cursor, remove forgets it.
• PluginInstallation.eventDelivery (forward-compatible optional) reports active | retrying | quarantined so a client can show it; the management UI PR renders it.
• Handler names starting with t3. are host-reserved: handle("t3.…") throws in the plugin process. Later stacked PRs open exactly three names, each with its capability: t3.tool.<name> (tools), t3.transform.enrich (context transforms) and t3.approval.decide (approvals). Every other t3.* stays refused.

No new RPC: plugins.resume already exists and keeps its access:write scope.

Size: 34 files, +3405 / −82. About 1.7k of the added lines are tests.

Evidence

Environment: macOS arm64; this PR on top of the plugin host PR.

How to exercise it (isolated vp run dev, administrative session): add, consent and enable a plugin whose entry calls context.proposed.onEvent(e => appendFile(log, JSON.stringify(e))), then run a turn with any provider. One run.finalized line appears after the turn's checkpoint lands, and the stored cursor equals that event's sequence.

Live trace (run on an earlier revision of this PR with an identical patch, before the stack was restacked; isolated server on a fresh home, macOS 26 arm64, Node 24; real Claude turns (claudeAgent, claude-opus-5-5) through the isolated server's default provider configuration; the fixture plugin appends each event to a file outside its directory, deduplicated by environmentId + deliveryId):

	Plugin host PR (parent)	This PR
Add a plugin declaring "capabilities": ["events"]	refused: this server does not support events	needs consent → enabled
Real Claude turn completes	run completed, 0 run.finalized records, no cursor table, 0 plugin processes	run.finalized at sequence 38, right after the checkpoint; plugin process launched; handler wrote Turn finished in "…turn 1": completed; cursor = 38

What the trace shows, in order:

1. Enable: the cursor row starts at the log head; no plugin process until the first page.
2. Delivery: a real turn persists checkpoint.captured (33, 34), run.updated (36), then run.finalized (38). The host launches the plugin, the handler runs, and the cursor is acknowledged at 38. plugins.list shows host running, eventDelivery: active.
3. Failing handler: with the handler throwing, plugins.subscribe shows retrying with failures 1–4 (retries 4 s, 8 s, 16 s apart), then quarantined with 5 failures. The server logs Quarantined a plugin's event delivery; the cursor stays at 38 while the log head is 75. Once the handler would succeed, delivery stays quarantined until plugins.resume, which delivers the page once (7th attempt) and moves the cursor to 75.
4. Plugin crash: the handler is held mid-page and the plugin process is killed with SIGKILL. The supervisor logs Plugin failed; backing off (was killed by SIGKILL, 1000 ms), starts a new process (new pid), and the same page is delivered again and acknowledged (cursor 112). The plugin's dedupe kept one notification.
5. Interrupted disable: with deactivate never settling, the first plugins.disable is interrupted by its client after 300 ms while the process is still alive. The retried disable returns 1.7 s later (2.0 s after the first call, the stop grace) and the process is gone.
6. Disabled, then restart: a turn finished while the plugin was disabled records run.finalized (149), but nothing is delivered and the cursor stays at 112. The server is stopped and started on the same home; the installation is still disabled and nothing is delivered. enable delivers sequence 149 from the cursor, and no acknowledged event is delivered again.
7. Restart while enabled: a further restart (into the --share run below) left the cursor at 153 and the attempt count unchanged.
8. Remove: the cursor row is deleted and no plugin process remains.

Remote pass (vp run dev --share, same isolated home, clients reached the server only through the tailnet HTTPS origin): a standard client read eventDelivery: active through plugins.list, then followed plugins.subscribe while a remote administrator ran a Claude turn with the handler failing. It saw idle → starting → running, retrying 1–4, then quarantined (5). Its own plugins.resume was refused (requiredScope=access:write); the administrator's resume delivered the page, and the standard client's plugins.list showed active again.

Checks at this head (55906e7fbb), re-run 2026-10-05 (CI=true, all exit 0):

• vp test run (apps/server) on RunFinalized.test.ts, RunFinalizationService.test.ts, EffectWorker.test.ts, PluginEventFeed.test.ts, the two migration-manifest tests, plus the plugin host's catalogue, supervisor and RPC-scope tests: 9 files, 88 tests pass. Contracts orchestrationV2.test.ts + pluginCatalog.test.ts: 2 files, 36 tests pass.
• Recorded during development: with only this PR's wiring reverted to its parent (new modules kept so the new tests load), RunFinalized.test.ts and PluginEventFeed.test.ts fail 29 of 30 tests (measured before the unreadable-identifier test was added); with all production files reverted, 5 server and 2 contracts tests fail and the two new files cannot load. The unreadable-identifier test fails against the previous revision of this PR (the worker died without quarantine, so Resume could not recover it) and passes now.
• RunFinalized.test.ts runs the real effect worker, outbox, SQLite event sink and projection, finalization service and restart recovery; only capture and refresh are stubbed. PluginEventFeed.test.ts runs the real catalogue and supervisor with real plugin child processes. Both wait on persisted events, worker drains and the feed's receipts; retry backoff is crossed with TestClock. None sleep.
• Neighbouring OV2 suites (run execution, checkpoint capture and rollback, restart recovery, replay recovery, persistence, relay, client projection and thread sync): 11 files, 257 tests pass on an earlier revision with an identical patch (not part of the re-run).
• vp run --filter typecheck for @t3tools/contracts, t3 and @t3tools/client-runtime; vp lint --report-unused-disable-directives and vp fmt --check on the touched files (one lint warning, unchanged from the parent: an unused daemonLayer in EffectWorker.ts); vp run knip:check; web build; vp run build:desktop; node scripts/release-smoke.ts. All pass.

Surfaces

• Entry points: none new. Plugin authors use context.proposed.onEvent; administrators use the existing plugins.resume. No settings, command palette or keybinding.
• Clients: web, desktop and mobile are unchanged. eventDelivery is added to installation snapshots; the management UI PR displays it. Clients that do not know it ignore it.
• Providers: provider-agnostic. Codex, Claude, Cursor, Grok, OpenCode, Antigravity and Pi all run turns as OV2 runs whose terminal status is written by the shared run execution path, never by the adapter, so every provider gets run.finalized through the same rule. Completed, interrupted and cancelled runs finalize after their checkpoint; failed runs finalize in their terminal commit; rolled-back runs never do. The plugin feed neither reads nor filters by provider. Live delivery at this head was exercised with Claude.
• Contracts: two new OV2 thread events, the plugin event projection and an optional eventDelivery installation field. New client + old server: no events, field absent (treated as unknown). Old client + new server: events are skipped as unknown; field ignored.
• Reverse states: quarantine ↔ plugins.resume; disable ↔ enable (continues from the cursor); remove forgets the cursor. A run.finalization-failed run never later records run.finalized.
• Connection modes: delivery is server-side between the event log and a local child process, so local, remote, relay and tunnel behave the same. The only wire change is the optional snapshot field on the existing plugin RPCs.
• Docs: one constraint paragraph in docs/internals/overview.md (exactly-one finalization record, committed with its work; EventSink owns the no-capture paths). No user doc yet: users cannot install plugins until the management UI PR, which adds the guide.

Not verified

• Live turns (on the earlier, identical-patch revision) used Claude only. Other providers are covered by the shared code path and the replay-harness tests, not by live turns.
• Runs that finished before this ships, and provider-native subagent nodes, never get run.finalized (by design); app-owned subagents finalize in their own threads.
• Delivery is at-least-once, not exactly-once: a crash between a plugin's side effect and the cursor write redelivers that page. Plugins must dedupe by environmentId + deliveryId.
• Quarantine state is in memory and clears on restart, so a plugin that keeps failing is retried 5 more times after each restart.
• The remote read of eventDelivery used the tailnet (--share) only, with a scripted RPC client rather than a browser (no client renders the field yet). No relay or T3 Connect tunnel run.
• No server was stopped while a turn was finishing; the "finished while away" case was shown with the plugin disabled across a restart instead.
• Windows and Linux plugin children were not run.

This pull request adds contribution-status streams and displays, run-finalization events, a local plugin runtime with management and event delivery, and a typed web side-panel registry with scoped panel operations.

Changes

Contribution Status

Layer / File(s)	Summary
Status contracts and server lifecycle packages/contracts/src/contributionStatus.ts, packages/client-runtime/src/state/contributionStatus.ts, apps/server/src/contributions/*, apps/server/src/orchestration-v2/Adapters/PiAdapterV2.ts	Shared schemas and capability-gated subscriptions carry full status snapshots. The server store validates, normalizes, limits, and publishes entries. Pi status sources follow session lifecycle changes and rollback outcomes.
Web and mobile presentation apps/web/src/components/chat/ThreadContributionStatus*, apps/mobile/src/features/threads/*, apps/mobile/src/lib/layout.ts	Web displays attributed status chips in a popover. Mobile displays a scrollable status strip and includes its reserved space in feed geometry.

Run Finalization

Layer / File(s)	Summary
Finalization contracts and processing packages/contracts/src/orchestrationV2.ts, apps/server/src/orchestration-v2/*, docs/internals/overview.md	Settled runs record run.finalized or run.finalization-failed. Checkpoint capture, workspace refresh, retries, cancellations, and restart recovery update these records.

Plugin Platform

Layer / File(s)	Summary
Plugin contracts and isolated execution packages/contracts/src/plugin*.ts, apps/server/src/plugins/PluginManifestLoader.ts, apps/server/src/plugins/PluginSource.ts, apps/server/src/plugins/PluginIpc*.ts, apps/server/src/plugins/PluginSupervisor.ts, apps/server/src/plugins/pluginHostChild.ts	Plugin manifests, catalog and event contracts, source digests, and bounded IPC are added. The supervisor runs plugins in child processes and manages invocation, cancellation, restart, and quarantine states.
Plugin catalog, event delivery, and server wiring apps/server/src/plugins/PluginCatalog.ts, apps/server/src/plugins/PluginEvent*.ts, apps/server/src/persistence/Migrations/*, apps/server/src/server.ts, apps/server/src/ws.ts, packages/contracts/src/rpc.ts	The catalog persists installations and digest-based consent. Event workers deliver projected events with persistent cursors. Migrations, RPC handlers, capabilities, and authorization expose these services.

Web Side-Panel Registry

Layer / File(s)	Summary
Typed registry and host integration apps/web/src/panels/panelRegistry.ts, apps/web/src/panels/bundledPanels.tsx, apps/web/src/panels/panelHost.ts, apps/web/src/components/ChatView.tsx, apps/web/src/components/RightPanelTabs.tsx	Panel metadata, typed lazy-loaded bodies, and shared host context replace direct panel rendering and per-panel launcher props.
Scoped panel operations apps/web/src/panels/device/*, apps/web/src/panels/preview/*, apps/web/src/panels/files/*, apps/web/src/panels/pullRequest/*, apps/web/src/browser/openFileInPreview.ts	Panels read thread state from the host context. Scope checks prevent late asynchronous work from updating a different thread visit.
Terminal panel and drawer apps/web/src/panels/terminal/*	The persistent terminal drawer and terminal panel are placed in the panel modules. Terminal launch locations and session IDs are derived from thread, project, and panel state.

Merge Risk: 🔵 Low · up to 9b2e9

The ChatView panel migration has no confirmed new blocker. Before merging the full PR, owners should address or explicitly accept the remaining plugin-message, documentation, and terminal-location concerns.

Security Architecture Review

Security architecture risk: 🟡 Moderate · up to 9b2e9

Approved local plugins can run automatically and receive activity across an environment. Administrative permissions and thread isolation limit exposure, but failure recovery, rollback, and some authorization paths have not been fully verified.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

• inferred — The documented plugin trust model is server-OS-user execution, so potential authority is broader than the metadata delivered over the event feed. The feed selects events across the environment rather than restricting an installation to one thread. This is an explicitly privileged extension boundary, not an established authorization bypass.

Trust Boundaries and Controls

• observed — Plugin add, refresh, consent, enable, disable, remove, and resume require administrative access scope. Orchestration command dispatch requires operate scope. The server installs authorization middleware against the authenticated WebSocket session's scopes, independently of client-side permission checks.
• observed — The panel annotation sender compares the originating environment-plus-thread key with the latest sender before forwarding. The inspected preview flow preserves existing preview and orchestration permission checks. Navigation does not redirect an old annotation callback into a different thread or environment.

Resilience and Maintainability Implications

• observed — The catalog serializes management operations, disables an enabled installation when reinspection no longer matches readiness, rejects calls prepared for a different registration generation, and reinspects source before admitting a call that requires fresh verification. These controls address replacement and approval drift; they are not proof of an OS sandbox.

Hardening Proposals

• proposed — For plugins performing security-sensitive external mutations, document and demonstrate durable deduplication using deliveryId. A successful handler followed by interruption or cursor-storage failure can be delivered again under the intended at-least-once contract.

Approvability

Verdict: Not approved

Macroscope's review found this PR not approvable — This PR introduces a broad plugin execution/event-delivery platform, durable orchestration records, authorization changes, and new user-visible provider status behavior across server, web, and mobile. It also changes product defaults and adds static-analysis suppressions, so the scope and sensitivity require human review.

Use the documented service shape for this module.

The effect-services guideline says: "No standalone FooShape; name the type Foo["Service"]." This module exports ContributionStatusStoreShape, and the adapter and tests import that name. The Context.Reference default-value pattern is a deliberate choice that lets adapters work without the store. Keep that pattern. Inline the interface in the tag, then switch consumers to ContributionStatusStore.ContributionStatusStore["Service"].

Nitpick comments:
Review comments at @apps/server/src/contributions/ContributionStatusStore.ts:
- Around line 88-97: Update the ContributionStatusStore Context.Reference to
define its service shape inline instead of relying on the standalone
ContributionStatusStoreShape type, while preserving the defaultValue behavior.
Update adapters and tests that import the shape to use the
ContributionStatusStore service type.

Review comments at @apps/server/src/plugins/PluginCatalog.ts:
- Around line 50-57: Change the PluginEventDelivery and PluginSupervisor imports
in PluginCatalog to namespace imports, then qualify their service and error type
references as PluginEventDelivery.PluginEventDelivery,
PluginSupervisor.PluginSupervisor, and PluginSupervisor.PluginInvokeError; use
the qualified service symbols in Effect.serviceOption and yield*.

apps/server/src/orchestration-v2/Adapters/PiAdapterV2.ts (1)

246-246: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

Type the store dependency as ContributionStatusStore.ContributionStatusStore["Service"].

PiAdapterV2Options.statusStore uses the standalone ContributionStatusStoreShape type. The service conventions forbid a standalone shape type for a service interface. Use the tag's Service type instead. makeGatedStatusStore in PiAdapterV2.test.ts (Line 442) uses the same alias. If no other code uses ContributionStatusStoreShape, remove its export from ContributionStatusStore.ts. Otherwise knip reports it as unused.

♻️ Proposed change

-  readonly statusStore: ContributionStatusStore.ContributionStatusStoreShape;
+  readonly statusStore: ContributionStatusStore.ContributionStatusStore["Service"];

As per coding guidelines: "Interface. No standalone FooShape; name the type Foo["Service"]."
