Enum OutputPolicy 

pub enum OutputPolicy {
    Passthrough,
    Verbatim,
    Compressible,
}

Central command output classification.

Every shell command flows through classify before any compression decision is made. This is the SINGLE source of truth — no other code path may bypass it.

Priority (first match wins):

1. User excluded_commands config → Passthrough
2. BUILTIN_PASSTHROUGH + dev scripts → Passthrough
3. Verbatim data commands → Verbatim
4. Everything else → Compressible (pattern engine decides specific vs generic later)

Variants

Passthrough

Auth flows, dev servers, interactive, streaming, installs. Output is passed through with ZERO modification, even when LEAN_CTX_COMPRESS=1 (force_compress) is set.

Verbatim

API data, file content, structured queries, HTTP responses. Output is preserved as-is. Only a hard size-cap is applied when the output exceeds the context window limit.

Compressible

Build, test, lint, package manager, git action output. Domain-specific pattern compression is applied, then generic fallback if no pattern matches.

Implementations

impl OutputPolicy

pub fn is_protected(&self) -> bool

Returns true if the output MUST NOT be compressed under any circumstances (not even truncated, except for catastrophic size).

Trait Implementations

impl Clone for OutputPolicy

fn clone(&self) -> OutputPolicy

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for OutputPolicy

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for OutputPolicy

fn eq(&self, other: &OutputPolicy) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
