PageKind

codetether_agent::session::pages

Enum PageKind 

Source 
pub enum PageKind {
    Bootstrap,
    Constraint,
    Plan,
    Preference,
    Evidence,
    Conversation,
}
Expand description

ClawVM page classification for a single chat-history entry.

Kinds are stable identifiers, not flags — a message has exactly one kind. The degradation path and minimum-fidelity invariant are encoded on PageKind itself (see min_fidelity and degradation_path).

Variants§

§

Bootstrap

System prompts and procedural directives. Losing them causes “forgot its protocol” failures (ClawVM §2).

§

Constraint

Hard-pinned invariants the agent must honour — codetether’s .tasks.jsonl goal entries map here natively.

§

Plan

Current objective and step. Live plan state.

§

Preference

Scoped user or project preferences.

§

Evidence

Tool outputs. Pointer-safe (Phase B): can degrade to a handle backed by the MinIO history sink.

§

Conversation

User / assistant conversation spans. The bulk of the transcript.

Implementations§

Source§

impl PageKind

Source

pub fn min_fidelity(self) -> ResidencyLevel

The minimum-fidelity level this kind is allowed to drop to.

Compression / eviction strategies that would drop a page below its minimum fidelity must be rejected (ClawVM §3), not silently applied.

§Examples
use codetether_agent::session::pages::{PageKind, ResidencyLevel};

assert_eq!(PageKind::Constraint.min_fidelity(), ResidencyLevel::Structured);
assert_eq!(PageKind::Evidence.min_fidelity(), ResidencyLevel::Pointer);
Source

pub fn degradation_path(self) -> &'static [ResidencyLevel]

The ordered sequence of residency levels this kind is allowed to visit, from full down to its minimum fidelity.

Used by Phase B’s DerivePolicy::Incremental to pick the next marginal downgrade when the token budget is tight.
