Enum ReadDedup 

pub enum ReadDedup {
    Auto,
    On,
    Off,
}

Controls the PostToolUse native-Read re-read dedup.

• Auto: (Default) dedup only on hosts with a read-before-write guard (Claude Code / CodeBuddy) — exactly where the PreToolUse redirect is off and the savings would otherwise be lost. Elsewhere the PreToolUse redirect already dedups re-reads, so the PostToolUse hook stays passive.
• On: dedup wherever the hook fires.
• Off: never replace a Read result.

Implementations

impl ReadDedup

pub fn from_env() -> Option<Self>

Parse LEAN_CTX_READ_DEDUP. Accepts the canonical auto|on|off plus the usual boolean spellings, mirroring LEAN_CTX_READ_REDIRECT.

pub fn effective(config: &Config) -> Self

Env override (LEAN_CTX_READ_DEDUP) wins over the on-disk config value.

pub fn read_dedup_enabled(config: &Config) -> bool

Whether the PostToolUse read-dedup may replace a re-read result in the current process/host. Auto restricts it to guard hosts, where the PreToolUse redirect is disabled and re-reads would otherwise flow at full size (#637 / GL #1140).
