Session switcher only shows a few sessions when many subagent sessions exist

[cwj2001]

Description

The TUI session switcher can show only a few top-level sessions when a project has many recently updated subagent/child sessions.

The sync cache loads recent sessions with the default server limit, then the session dialog filters out child sessions on the client. If child sessions consume most of that limit, older top-level sessions are absent from the non-search /sessions list even though they still exist and can be found by search.

Plugins

None required

OpenCode version

1.17.7

Steps to reproduce

1. Use a project with more than 100 recent sessions where most are subagent/child sessions.
2. Open the TUI session switcher with /sessions.
3. Observe that only a small subset of top-level sessions is shown.
4. Search for an older top-level session and observe that it can still be found.

This issue might be a duplicate of existing issues. Please check:

• TUI session list can hide sessions when recent rows are subagents #30606: TUI session list can hide sessions when recent rows are subagents (same root cause: client-side filtering after server-limited fetch lets child sessions crowd out root sessions)
• bug(tui): Switch Session can hide recent root sessions behind child sessions #23277: bug(tui): Switch Session can hide recent root sessions behind child sessions (identical repro scenario and mechanism)
