Problem

OpenCode progress could appear as assistant text or attach to the wrong response. Reasoning summaries were hard to find among tool activity, while long raw traces could crowd the chat. Late and recovered replies also needed to stay with their original turn.

What changed

  • Show concise reasoning summaries inline. Raw traces stay behind a bounded disclosure; long summaries have their own Show more control.
  • Keep OpenCode text parts separate until their final classification is known, so tool-call progress cannot be appended to an earlier answer. Reasoning-only turns no longer get a synthetic empty assistant message.
  • Share the response-fold and reasoning-display rules used by web and mobile. Expanded tool calls remain in their bounded virtual list, with their scroll position restored when reopened.
  • Preserve turn association for late and recovered replies across provider, server, and client updates.

Validation

  • Focused adapter, ingestion, web timeline, mobile feed, projector, and reducer suites: 522 passed, 1 skipped.
  • Targeted lint, formatting, and typechecks passed for changed packages.

Approvability

Verdict: Not approved

Macroscope's review found this PR not approvable — This PR substantially changes the default chat experience and OpenCode runtime lifecycle across web, mobile, server, persistence, and shared contracts. The new inline reasoning capability and turn/recovery handling are broad enough to require human review rather than automatic approval.

📝 Walkthrough

Walkthrough

The PR classifies provider progress as reasoning, updates message projections, and changes mobile and web timelines to distinguish summaries from raw traces. It also changes turn folding, empty-answer handling, tool-group expansion, and OpenCode response recovery.

Changes

Reasoning progress and timeline

Layer / File(s) Summary
OpenCode response and progress events
packages/contracts/src/providerRuntime.ts, apps/server/src/provider/Layers/OpenCodeAdapter.ts, apps/server/src/provider/Layers/OpenCodeAdapter.test.ts
The runtime contract adds progress stream and presentation values. The adapter classifies continuation text, tracks message-to-turn associations, and confirms assistant completion after idle or reconnect recovery.
Reasoning message ingestion and projection
apps/server/src/orchestration/..., apps/server/src/persistence/..., packages/client-runtime/src/state/threadReducer.ts
Ingestion dispatches progress as reasoning. Projection repositories resolve replacement assistant messages by turn. Projectors and the client reducer update roles and assistant-message references after reclassification.
Mobile feed grouping and rendering
apps/mobile/src/lib/threadActivity.ts, apps/mobile/src/features/threads/ThreadFeed.tsx
The mobile feed derives active turns, preserves terminal empty answers, classifies reasoning, and adjusts folds for active or failed work. Summary reasoning uses bounded expandable content.
Web reasoning and tool timeline
apps/web/src/components/chat/MessagesTimeline.logic.ts, apps/web/src/components/chat/MessagesTimeline.tsx, apps/web/src/components/chat/*.test.tsx, docs/user/activity-groups.md
The web timeline replaces activity-group rows with reasoning-run rows, separates summary and raw reasoning, updates folding and streaming behavior, and renders expanded tool entries below toggle rows. Tests and documentation cover these presentation changes.

Merge Risk: 🔵 Low · up to 95f43

Expanded mobile activity can show a misleading empty-response placeholder in the middle of a completed turn. The issue is limited to that display path and is suitable for owner follow-up.

Security Architecture Review

Security architecture risk: 🟡 Moderate · up to 95f43

Progress now passes through several layers before appearing in a thread. The normal turn-completion path has safeguards, but a progress event without a turn identifier can be shown without clear turn ownership. No access-control bypass was established.

Retained concerns

  • Medium · reliability · inferred: OpenCode progress can be projected without turn ownership when neither a remembered message association nor an active turn supplies a turn ID. The server then finalizes that message immediately, leaving its relationship to a completed or recovered turn unclear.
Security review details

Security Blast Radius

  • inferred — The newly projected text can affect readers of the associated thread across web and mobile. Evidence does not establish cross-tenant exposure, a new privileged capability, or an independently reachable public endpoint.

Trust Boundaries and Controls

  • observed — The adapter emits typed provider events into an internal stream, and server ingestion projects progress using the existing reasoning role. Whether an attacker can influence that text, and whether public thread reads enforce unchanged identity and tenant controls, remains unverified.

Resilience and Maintainability Implications

  • inferred — Message IDs prevent a repeated progress event from necessarily creating another row, but they do not by themselves prevent repeated streaming text from being appended. The inspected tests of terminal completion do not establish exact-delta replay behavior.

Hardening Proposals

  • proposed — Establish a turn-ownership rule for progress events that arrive after interruption or recovery, and verify exact-event replay behavior before relying on progress text as a faithful account of a turn.

- Around line 1579-1580: Update groupAdjacentActivities so intermediate empty
assistant messages do not split activity runs, while the terminal empty

empty-message retention to terminal answers. Preserve grouping of tools from the
same turn across intermediate empty assistant messages.

In `@apps/server/src/orchestration/Layers/ProjectionPipeline.ts`:
- Around line 1572-1596: In the reasoning branch, replace the listByThreadId
full-message scan and findLast search with a projectionThreadMessageRepository
query that returns only the latest assistant message ID for the event’s thread
and turn, excluding the reclassified message. Update assistantMessageId from
that query’s optional result while preserving null when no replacement exists.

In `@apps/server/src/provider/Layers/OpenCodeAdapter.ts`:
- Around line 1519-1544: In the idle-recovery branch for
`promptAdmission.messageObserved`, check `session.messages` for a finished
assistant reply whose `parentID` matches `promptAdmission.messageId` before
awaiting `responseReceipt`. When its finish is `stop` or `length`, set
`assistantResponseFinished` and reconcile the idle status; retain the existing
receipt wait and timeout recovery when no finished reply is found.

In `@apps/web/src/components/chat/MessagesTimeline.tsx`:
- Around line 2351-2353: When activity.unsettledTurnId is null, keyed streaming
messages should use activity.isWorking instead of being treated as settled. Add
one shared predicate and use it for the streaming checks in
AssistantTimelineRow, SummaryReasoningTimelineRow, RawReasoningTimelineRow, and
the raw details list; preserve turn-ID matching when an unsettled turn is known.

In `@apps/web/src/components/chat/MessagesTimeline.logic.ts`:

same grouping when looking up stats in displayKind and
replaceStreamingMessageRows. Add a test with a turnless summary and raw message
after a user message, verifying they render as two reasoning-run rows.

In `@packages/contracts/src/providerRuntime.ts`:
- Line 85: Update the `TestProviderAdapter.integration.ts` content-delta

Note

This comment is posted by Julius' dot

The shared web/mobile changes make reasoning summaries read inline by default and change how completed reasoning folds, beyond the OpenCode progress-classification repair. Those intentional presentation defaults need prior maintainer direction and scope approval, which isn't linked or present here. The before/after captures and focused test results are useful, but don't replace that approval. Closing for now: agree on the display direction with maintainers and request reconsideration, or submit a focused repair that preserves the current presentation.
