Error message

pipeline(): max 1000 items per call

What it means

Startup warning: tui.toml exists but does not parse as TOML - the raw file is re-parsed as toml::Value after TuiPrefs::load already fell back to defaults. The TUI starts with default UI preferences and surfaces this warning instead of silently dropping the configuration.

Solutions

1. Fix the syntax error at the position given by the ({e}) message
2. Validate with a TOML parser/linter before relaunching
3. If unsure, regenerate the file from defaults and re-apply the preferences

Example fix

# before (tui.toml)
[scrollback
lines = 10_000
# after
[scrollback]
lines = 10000

// Same guard for UI prefs: parse tui.toml before launch.
let raw = std::fs::read_to_string(tui_prefs_path)?;
toml::from_str::<toml::Value>(&raw)?;

When it happens

Trigger: TOML syntax errors in tui.toml: unclosed strings or tables, duplicate keys, merge-conflict markers, or truncated writes.

Common situations: Manual edits with typos; git merge conflicts; a sync tool truncating the file while copying dotfiles between machines.
