Webapp keeps stale blue task indicators after sessions return idle/completed

[OpenCodeEngineer]

Summary

Regression on deployed webapp (100.108.64.76:4096): blue dot task indicators remain visible even after tasks/sessions are completed and status is idle.

User impact

Sidebar/task state appears stale, suggesting unfinished work when backend session is already completed/idle.

Initial evidence

• Reproduced on live page path under .../witty-squid/session/....
• URL can recover to session list while blue indicator persists.
• Prior related area: stale busy/status handling in Fix workspace thrash, stale busy status, and noisy MCP startup errors on remote serve #146.

Scope

• Trace indicator source of truth (unseen/session status/toast state) in app state reducers and sidebar rendering.
• Confirm whether /session/status and event stream payloads are correct vs local derived state.
• Fix stale indicator cleanup when session transitions to idle/completed.
• Add regression test coverage.
• Redeploy remote opencode-serve.

Triage update:

• Reproduced on live web UI with browser inspection.
• Blue dots are currently driven by notification.*.unseenCount (turn-complete notifications), not by active run state.
• This causes completed/idle tasks to keep a blue indicator until separate viewed-marking paths run.

Implementing a frontend fix so completed/idle tasks do not show blue dots (while preserving spinner for active work and warning/error indicators).

[OpenCodeEngineer]

Implementation ready on branch fix/no-blue-complete-dots.

Change summary:

• Removed blue session-row indicator tied to completion-unseen notifications.
• Project tile indicator now only shows warning/error attention states (no generic blue completion dot).
• Spinner (active), warning, and error indicators remain.

Opening PR now, then merging and redeploying to remote VM.

Merged PR #214 to dev and redeployed on remote VM.

Deployment details:

• Merge commit: 61c2dcb
• Service: opencode-serve (azureuser@100.108.64.76)
• Health: {"healthy":true,"version":"0.0.0--202605190054"}
• Served app asset: assets/index-DcEtHvB9.js

Status: completed.

Post-deploy live check on the reported URL confirms the session list is no longer rendering blue completion dots (bg-text-interactive-base).

Current indicator scan in the sidebar found only one red error indicator (bg-text-diff-delete-base) for an error session, which is expected behavior.
