Struct DerivedContext 

pub struct DerivedContext {
    pub messages: Vec<Message>,
    pub origin_len: usize,
    pub compressed: bool,
    pub dropped_ranges: Vec<(usize, usize)>,
    pub provenance: Vec<String>,
    pub resolutions: Vec<ResidencyLevel>,
}

The per-step LLM context, derived from an append-only chat history.

This is the object the prompt loop should hand to the provider — not Session::messages directly.

Fields

• messages — The message list to include in the completion request.
• origin_len — Length of the source history at the moment of derivation.
• compressed — Whether compression fired during this derivation.
• dropped_ranges — Best-effort ranges elided from the working context.
• provenance — Pipeline steps that produced this context.
• resolutions — Per-message residency levels in the derived context.

Examples

use codetether_agent::session::context::DerivedContext;

let derived = DerivedContext {
    messages: Vec::new(),
    origin_len: 0,
    compressed: false,
    dropped_ranges: Vec::new(),
    provenance: Vec::new(),
    resolutions: Vec::new(),
};
assert_eq!(derived.origin_len, 0);
assert!(!derived.compressed);

Fields

messages: Vec<Message>

Messages to send to the provider this turn.

origin_len: usize

session.messages.len() at the moment of derivation.

compressed: bool

true when any compression / truncation pass rewrote the clone.

dropped_ranges: Vec<(usize, usize)>

Best-effort elided ranges from the source history.

provenance: Vec<String>

Names of the pipeline stages that shaped this context.

resolutions: Vec<ResidencyLevel>

Per-message residency level in the derived context.
