md-first memory extraction framework for AI agents. Markdown is the single source of truth; SQLite holds state and LanceDB provides the rebuildable vector + BM25 + scalar index. The codebase follows a single-direction DDD layering (entrypoints -> service -> memory -> infra, with component / core / config cross-cutting) enforced by import-linter. Engineering surface: - Coding conventions in .claude/rules/ (path-scoped) and workflows in .claude/skills/ (/commit, /new-branch, /pr). - GitHub Actions CI runs make lint + test + integration; pre-commit mirrors the gates locally (ruff, hygiene hooks, gitlint commit-msg). - Commit messages follow Conventional Commits, enforced by gitlint. - make lint also enforces datetime two-zone discipline and OpenAPI drift.

# Architecture rule (always loaded)
|
|
|
|
EverOS is a DDD-layered framework. The dependency direction is **single, downward only**:
|
|
|
|
```
|
|
entrypoints → service → memory → infra
|
|
↓
|
|
component / core / config
|
|
```
|
|
|
|
- `entrypoints/` — CLI + HTTP API (presentation). No business logic.
|
|
- `service/` — use-case orchestration (memorize / retrieve / evolve / manage).
|
|
- `memory/` — domain (extract / search / cascade / prompt_slots / models).
|
|
- `infra/` — storage adapters (markdown + sqlite + lancedb) and the OME subsystem.
|
|
- `component/` — injectable providers (llm / embedding / config / utils).
|
|
- `core/` — runtime base (observability / lifespan / context / persistence primitives).
|
|
- `config/` — configuration data (Settings + default TOML).
|
|
|
|
## Hard constraints (enforced by `import-linter`, run in `make lint`)
|
|
|
|
1. **Layering**: an outer layer may import an inner layer, never the reverse.
|
|
`entrypoints → service → memory → infra`.
|
|
2. **Private internals**: `service`, `memory`, and `entrypoints` must not import
|
|
`infra.persistence.{markdown,lancedb,sqlite}.**` internals — go through the
|
|
package facade (`from everos.infra.persistence.markdown import ...`).
|
|
3. **OME isolation**: `infra.ome` must not import `persistence`, `memory`,
|
|
`service`, or `entrypoints`. It is a low-level scheduler with no domain knowledge.
|
|
|
|
If a change needs to cross a boundary the wrong way, the design is wrong — refactor,
|
|
don't add an exception.
