fix(opencode): keep tool-call progress out of assistant answers

[Adamulek123]

What changed

Extracts the OpenCode progress-classification repair from #13128, following the maintainer's request for a focused repair that preserves the current presentation.

OpenCode text that finishes with tool-calls becomes progress in the existing reasoning stream. Text parts stay separate until classification, so reclassifying one part cannot absorb an earlier answer. Switching parts completes the previous projected message even when its text buffer is empty. Approval and blocking-question boundaries flush and complete progress messages while the turn waits for input. Late classification and text updates retain their original turn.

Server projections and the shared client reducer update the message role and repair assistant references in turns and checkpoints. The reducer uses the server's existing 2,000-message cap. The test adapter collects only assistant-text deltas into its synthetic answer.

Web, desktop, mobile presentation, user docs, and prompt-admission/response-recovery behavior remain unchanged from main. Inline reasoning summaries are deferred to an Ideas discussion.

Why

A regression fixture on main shows Checking the reviews. appended to the preceding assistant message, producing Starting the review.Checking the reviews.. With this repair, the preface remains Starting the review., progress is its own reasoning message, and the final answer remains The review is complete..

The adapter only learns that assistant text was continuation progress when its parent finishes with tool-calls. Ingestion previously combined parts, and projections retained assistant references after reclassification. Correcting classification therefore needs the adapter, ingestion, persistence, and shared state changes together. Turn association lets a delayed classification update the same message and turn after another turn begins.

Validation

• Seven focused suites: 337 passed, 1 skipped. Covers OpenCodeAdapter, ProviderRuntimeIngestion, ProjectionPipeline, projector, ProjectionThreadMessages, threadReducer, and TestProviderAdapter.
• reclassifies completed OpenCode progress text without changing the final answer fails with main's ingestion and passes with the repair.
• Four settles the previous OpenCode part regressions fail before the part-switch completion fix and pass afterward. Covers token/paragraph delivery and completed/aborted turns without an item-completed event.
• Six pause-boundary cases cover token/paragraph delivery, approval, blocking questions, asynchronous questions, and resumed progress. The four blocking cases fail before the pause fix and pass afterward; asynchronous questions keep streaming.
• Adapter coverage checks tool-call progress, length/stop answers, retained text, and late reports. All existing prompt lifecycle tests pass with main's lifecycle behavior.
• Server typecheck, targeted lint, and formatting passed after the review changes. Contracts and client-runtime typechecks passed for the original extraction and their code has not changed since.
• Ingestion regressions wait on enqueue receipts and worker drains. No live provider or browser verification was performed.

Approvability

Verdict: Not approved

Macroscope's review found this PR not approvable — This repair changes OpenCode’s live streaming classification and the server/client state used to persist and display messages across several production layers. Its intent and regression coverage are clear, but the cross-layer state and late-event behavior are substantial enough to require human review.

Note

This comment is posted by Julius' dot

The classification and projection changes follow the focused repair suggested in #13128. OpenCodeAdapter also changes prompt admission to wait for a finished assistant response and recover lost terminal events. Why are those lifecycle changes necessary for the progress-classification fix? Please explain the dependency under the one-problem rule, or split them if they fix a separate problem.

The changes add OpenCode progress-text events and route progress messages through ingestion as reasoning. Server and client projections update assistant-message references when a message is reclassified.

OpenCode event association and progress classification apps/server/src/provider/Layers/OpenCodeAdapter.ts, apps/server/src/provider/Layers/OpenCodeAdapter.test.ts, packages/contracts/src/providerRuntime.ts	The adapter classifies progress text, associates messages with turns, and emits progress completions.

The persistence query selects the latest other assistant message for the turn. Tests cover these updates and message-history limits.

Security Architecture Review

Security architecture risk: 🔵 Low · up to 4b039

Separating progress from answers is a bounded change with explicit turn-ownership protections. No new permission or cross-session access was identified, but event-ordering and interruption recovery are not fully established.

No architecture-level concerns identified.

Security review details

Security Blast Radius

• inferred — The inspected exposure is provider-controlled message content and identifiers affecting the associated conversation's displayed messages and persisted turn references. Session filtering and thread/turn-scoped reference lookup constrain this path; the reviewed changes do not demonstrate expanded access to another session or data store.

Trust Boundaries and Controls

• observed — Before classification, message events are filtered to the parent session, with related-child handling restricted to request events. Existing runtime-mode permission rules are applied when sessions are created, resumed, or forked. Progress classification does not replace these controls.

Resilience and Maintainability Implications

• observed — The subscription processes events sequentially, and retained classification guards repeated progress completion. However, finish-time classification visits only currently retained parts, while a newly retained part defaults to unclassified. The inspected test supplies text before the finish event; provider ordering and interrupted-emission recovery remain unverified rather than established vulnerabilities.

@juliusmarminge

The prompt-admission wait and session.messages recovery solve an independent lifecycle problem. I removed those changes and their test adjustments in d3dd881, rather than claiming they are prerequisites for classification. Prompt admission, cancellation, and terminal-response recovery now match main.

The remaining message-to-turn associations are needed for delayed classification: a tool-calls finish can reclassify text after its original turn completes or after a newer turn starts. Routing that update through the current active turn would change the wrong turn's message state. Classification and late-routing coverage pass with main's lifecycle restored.

The updated description reflects this narrower scope. Seven focused suites passed: 331 tests passed, 1 skipped. The streaming-part finding was fixed separately in 0fbe94b.

@coderabbitai review

Please review the latest commit, 4b039fc. The previous part-switch finding is fixed with four regression cases. Independent prompt recovery changes were removed, and classified progress now settles at approval/blocking-question boundaries with six additional cases. Focused validation: 337 passed, 1 skipped; server typecheck, targeted lint, and formatting pass.

Thanks for working on this. We merged the orchestrator V2 rewrite in #2829, and we are closing this PR as part of that transition.

This change touches ProjectionPipeline.ts, ProviderRuntimeIngestion.ts, projector.ts, which the V2 merge removed. OpenCode execution now uses V2 adapters and V2 run state.

Sorry for the extra work this creates. If the change is still needed on V2, please rebuild it on current main, verify it there, and open a new PR linking back here. We're closing the current implementation without assuming the underlying request is resolved.
