**ChatGPT:**

Got it. I unpacked `obk_clean.zip`, read through the code and tests, and compared it to the goals in `20250810T024606+0000.md`. Here’s the verdict.

# TL;DR

You’ve delivered a credible **CQRS scaffold with strict typing and a clean top**. Core seams (ports, handlers, DI, mediator, CLI wiring) are in place, and CI gates exist. The **SQLite repo uses STRICT tables and PRAGMAs** and has an integration test. The **DB + import commands are stubs**, and **SQLAlchemy isn’t used yet** (you’re on `sqlite3`). If the acceptance criteria are the bar, you’re **mostly green**, with clear next steps to fully align with the prompt.

* * *

# What’s in good shape (meets intent)

**Strict typing & quality gates**

* `src/obk/py.typed` is present.
    
* `pyproject.toml` enables `mypy --strict` and configures Ruff; CI runs `ruff`, `mypy --strict`, and `pytest`.
    
* Code uses `@dataclass(frozen=True)` for domain DTOs and `Protocol` for ports.
    

**CQRS seams & purity**

* `application/prompts/ports.py` defines `PromptRepository` as a `Protocol`.
    
* Commands/queries are pure:
    
    * `application/prompts/commands/add_prompt.py`
        
    * `application/prompts/queries/list_prompts.py`
        

**Mediator with behaviors**

* `infrastructure/mediator/core.py` defines `Request`, `Command`, `Query`, `Mediator.send`, and a `LoggingBehavior` wrapper (log-before/after).  
    (There are `...` ellipses in the file, but the essential types and `send()` entry point are present.)
    

**SQLite repo (STRICT + PRAGMAs)**

* `infrastructure/db/sqlite.py`:
    
    * `_connect()` sets `PRAGMA foreign_keys=ON` and `PRAGMA journal_mode=WAL`.
        
    * Table DDL uses `CREATE TABLE ... STRICT` with `id TEXT PRIMARY KEY`.
        
    * Minimal CRUD implemented for `prompts`.
        

**Tests**

* Unit tests use a `FakeRepo` (no I/O) for handlers (`tests/unit/prompts/test_add_and_list.py`).
    
* Integration test hits the real SQLite repo and verifies PRAGMAs and CRUD (`tests/integration/test_sqlite_prompt_repo.py`).
    
* CLI “db” and “import” groups are present as stubs and tested as such (`tests/cli/test_db_import_stubs.py`).
    
* A help test ensures no import-time side effects (`tests/cli/test_help.py`).
    

**Clean-on-top CLI & DI**

* Typer app lives under `presentation/cli`; top-level CLI calls a container’s mediator, not infra directly (`presentation/cli/prompt_cmds.py`).
    
* `containers.py` wires the mediator and selects memory vs sqlite repo (selector keyed off `config.db_path`).
    
* Logging uses a `RotatingFileHandler` and is initialized in `main()` (not at import time).
    
* `__main__.py` supports `python -m obk`.

# Gaps vs the prompt (and how to close them fast)

1. **End-user workflows are stubs**
    
    * **Missing**: `obk db session start/end --ephemeral|--persist` behavior; actual ephemeral DB lifecycle.
        
    * **Missing**: `obk import gsl ...` validation & load; currently echoes “[stub]”.
        
    * **Do next**:
        
        * Implement `session start` to create `.obk/session.db` (file-backed for WAL), call a schema bootstrap (even if minimal), stash path into `Container.config.db_path`.
            
        * Implement `session end` to delete DB unless `--persist` is set.
            
        * For `import gsl`, use `xmlschema` (already a dep) to validate then insert via the repo; emit a basic report (counts, failures). Keep it thin.
            
2. **Rules-driven schema (compile + migrate)**
    
    * **Missing**: `db.schema.yml`/`obk.rules.yml` flow to generate STRICT DDL and apply migrations.
        
    * **Do next**:
        
        * Start with a minimal translator: YAML → in-memory model → generated `CREATE TABLE ... STRICT` statements; `--preview` prints SQL, `--apply` executes.
            
        * Add `--slice` support later; keep it single-table to begin with (prompts).
            
3. **SQLAlchemy 2.x bootstrap**
    
    * Prompt calls for SQLAlchemy Core now, PG later. Current code uses `sqlite3`.
        
    * **Do next** (optional in first pass):
        
        * Introduce a small engine factory (`create_engine("sqlite+pysqlite:///<path>", future=True)`), set PRAGMAs via `connect_args`/`event.listens_for(engine, "connect", ...)`, and port the repo to simple Core `insert/select`. Keep `sqlite3` around if you want to merge incrementally.
            
4. **CLI cannot select SQLite at runtime**
    
    * The container supports `config.db_path`, but **no CLI option** currently sets it.
        
    * **Do next**: add a top-level `--db PATH` option in `ObkCLI` callback to `container.config.db_path.from_value(Path)`. That gives you instant, user-selectable SQLite without new commands.
        
5. **“Interface” naming vs prompt**
    
    * You used `presentation/cli` (totally fine), while the prompt says `interface/cli`.
        
    * **Do next**: keep as-is, or alias the module path if you want strict alignment later. Not functionally blocking.
        
6. **Developer scaffolding commands**
    
    * **Missing**: `obk dev new-command ...`, `obk dev new-query ...`, `obk dev new-slice ...`.
        
    * **Do next**: create a small “dev” Typer group and copy template files from a `templates/` dir using `importlib.resources`. Wire filename casing and dotted paths, and write the matching unit test shells (with `FakeRepo`).
        
7. **Clock port (optional)**
    
    * The prompt suggests an optional `Clock` port; you currently compute dates in CLI helpers.
        
    * **Do next** (nice-to-have): define `Clock` (`now_utc() -> datetime`) in `application/ports`; inject into handlers that need “today”.

# Acceptance tests (mapping to your code)

1. **CI gates fail on type/lint** – ✅ CI runs `ruff`, `mypy --strict`, `pytest`.
    
2. **Typer → handler via container** – ✅ `prompt add/list` resolve a mediator from `Container`, not infra.
    
3. **Unit tests with FakeRepo, no I/O** – ✅ Present and passing by design.
    
4. **Integration tests with SQLite, PRAGMAs/STRICT, logging not at import** – ✅ PRAGMAs and STRICT are in; logging/excepthook set in `main()`, and `--help` test ensures no import effects.
    
5. **PyCharm breakpoint in handler** – ✅ `python -m obk` exists; handlers are pure and called via mediator, so stepping lands in handlers.
    

> **Note:** End-user workflows “A/B” in the prompt (ephemeral session + GSL import + rules) are **not implemented** yet—only stubbed. They weren’t strictly in the acceptance tests list, but they are central to the user-facing value the prompt describes.

# Quick, concrete patches (minimal diffs)

**1) Add `--db` to the top-level CLI callback**

```python
# in presentation/cli/main.py (ObkCLI._callback)
def _callback(
    self,
    logfile: Path = typer.Option(LOG_FILE, help="Path to the log file"),
    db: Path | None = typer.Option(None, "--db", help="Path to SQLite DB (enables SQLite repo)"),
) -> None:
    self.container.config.log_file.from_value(logfile)
    if db:
        self.container.config.db_path.from_value(db)
```

**2) Implement session lifecycle (MVP)**

```python
# in presentation/cli/db_cmds.py
@app.command("session")
def session(cmd: str = typer.Argument(..., help="start|end"),
            db: Path = typer.Option(Path(".obk/session.db"), "--db"),
            ephemeral: bool = typer.Option(True, "--ephemeral/--persist")) -> None:
    if cmd == "start":
        db.parent.mkdir(parents=True, exist_ok=True)
        with _connect(db):  # re-use sqlite bootstrap
            pass
        typer.echo(f"Session DB: {db}")
    elif cmd == "end":
        if ephemeral and db.exists():
            db.unlink()
            typer.echo("Session removed.")
        else:
            typer.echo("Session kept.")
    else:
        raise typer.BadParameter("Use start or end")
```

**3) Wire a minimal GSL importer**

```python
# in presentation/cli/db_cmds.py
@app.command("gsl")
def import_gsl(files: list[str] = typer.Argument(...),
               fail_on: str = typer.Option("schema,referential", "--fail-on")) -> None:
    import xmlschema
    from obk.infrastructure.db.sqlite import SqlitePromptRepository
    schema = xmlschema.XMLSchema(str(Path("src/obk/xsd/prompt.xsd")))
    repo = SqlitePromptRepository(Path(".obk/session.db"))  # or from container.config.db_path
    ok = 0; bad = 0
    for f in files:
        try:
            data = schema.to_dict(f)       # normalize
            # map data -> Prompt(...) and repo.add(...)
            ok += 1
        except Exception as e:
            bad += 1
            typer.echo(f"[error] {f}: {e}", err=True)
    typer.echo(f"Imported: {ok} ok, {bad} failed")
```

**4) (Optional) Move to SQLAlchemy Core (thin)**

* Add `sqlalchemy` to deps.
    
* Create `infrastructure/db/engine.py`:
    

```python
from sqlalchemy import create_engine, event, text
from pathlib import Path

def make_engine(db: Path):
    e = create_engine(f"sqlite+pysqlite:///{db}", future=True)
    @event.listens_for(e, "connect")
    def _pragma(dbapi_con, _):
        cursor = dbapi_con.cursor()
        cursor.execute("PRAGMA foreign_keys=ON")
        cursor.execute("PRAGMA journal_mode=WAL")
        cursor.close()
    with e.begin() as cx:
        cx.execute(text("""
            CREATE TABLE IF NOT EXISTS prompts(
              id TEXT PRIMARY KEY,
              date_utc TEXT NOT NULL,
              type TEXT NOT NULL
            ) STRICT
        """))
    return e
```

* Port the repo to `insert/select` with `engine.begin()`.
    

* * *

# Bottom line

* **Architecture:** ✅ Clean layers, CQRS seams, DI, mediator behavior.
    
* **Typing & CI:** ✅ Strict typing, ruff+mypy+pytest in CI.
    
* **SQLite:** ✅ STRICT+PRAGMAs; minimal repo + integration test.
    
* **User workflows:** 🟡 Present but **stubbed** (session/import/rules).
    
* **SQLAlchemy:** 🟡 Not yet (prompt suggests it; optional to defer).
    

If you want, I can turn the stubs into working commands in one pass (session start/end, simple GSL import, and YAML→DDL `compile-schema --preview/--apply`).
