Deep implementation details for src/core/ — task model (5 text fields, phase lifecycle, dependencies, session slots, child tasks), session monitoring (3-layer), message queue & FIFO/JSONL delivery patterns, daemon-uniform file access rule, chat history compaction. Use when implementing or debugging anything in src/core/ or the session data layer.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Core Layer — Implementation Details Detailed internals for `src/core/`. For architecture overview, see project `CLAUDE.md`. ## Task Model Details ### Task text fields (5-field model) Each task has `description` (what & why — pre-action context, user-set), `summary` (TL;DR of progress — AI-maintained), `note` (detailed markdown blob — evolving, append via `addNote()` or replace via `updateNote()`), and `conversation_log` (append-only markdown log of user↔agent interactions, auto-managed by the chat handler via `appendConversationLog()`). The conversation_log is automatically appended server-side after every chat turn where a task is focused — each entry has a `### YYYY-MM-DD HH:MM` timestamp heading followed by `**User:**`/`**AI:**` summaries (truncated to 150/200 chars). The field is optional, starts as `undefined`, and is created on first interaction. Migration from the old `notes: string[]` is handled by `migrateNotesToFields()` in `task-manager.ts`. …

How to install
mdr add evanzhang008/open-walnut/walnut-core-internals@sha256:a99da5bc66fb9519The line at the top of this page pins the label git:20260929.89b1b35, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
