Struct OverflowConfig 

pub struct OverflowConfig {
    pub threshold: usize,
    pub retention_days: u64,
    pub max_overflow_bytes: usize,
    pub max_per_call_override: usize,
}

Configuration for large tool response offload to SQLite.

Fields

threshold: usize

Character threshold above which tool output is offloaded. Default: 50000.

retention_days: u64

Days to retain offloaded entries. Default: 7.

max_overflow_bytes: usize

Maximum bytes per overflow entry. 0 means unlimited. Default: 10 MiB.

max_per_call_override: usize

Hard ceiling (in chars) on a per-call result-size override that an MCP server may request via _meta["zeph/maxResultSizeChars"]. The server’s request is clamped to min(requested, max_per_call_override) and may only raise the effective limit above threshold, never lower it. A value at or below threshold disables per-call overrides entirely. Raising the effective limit also enlarges how much of that call’s output counts against the turn’s context budget, not just summarizer cost. Default: 131072 (128 KiB).

Note: unlike max_overflow_bytes, 0 here does NOT mean “unlimited” — it disables overrides (the clamp floors at threshold).

Note: for sanitized (external/untrusted, :-qualified) MCP output, the effective in-context ceiling under default config is actually zeph-sanitizer’s ContentIsolationConfig::max_content_size (65536 bytes by default), which is smaller than this field’s 131072-char default and caps what reaches the LLM downstream of this clamp — a fail-safe (lower, not higher) bound, not a hole.
