Crate zeph_context 

Context budget, lifecycle management, compaction strategy, and context assembler for Zeph.

This crate contains the stateless and data-only parts of context management extracted from zeph-core. It has no dependency on zeph-core — callers in zeph-core implement the input::IndexAccess trait for their own types and populate input::ContextMemoryView before each assembly pass.

Modules

• budget — budget::ContextBudget and budget::BudgetAllocation
• manager — manager::ContextManager state machine and manager::CompactionState
• assembler — assembler::ContextAssembler parallel fetch coordinator
• input — input::ContextAssemblyInput, input::ContextMemoryView, traits
• slot — slot::ContextSlot, slot::CompactionOutcome, helper functions
• summarization — pure prompt-building helpers for context compaction
• turn_context — turn_context::TurnId, turn_context::TurnContext per-turn carrier
• compression_feedback — context-loss detection and failure classification
• microcompact — low-value tool detection helpers for time-based microcompact
• fidelity — heuristic fidelity scorer for Context-Adaptive Memory (CAM)
• tool_result_compress — per-result and batch-level token budget enforcement for tool outputs
• typed_page — typed page classification and minimum-fidelity invariants for compaction
• error — error::AssemblerError
