+# The DisExcel Project — Context for Claude Code
+
+Backend: FastAPI + SQLAlchemy (async) + Pydantic v2 + PostgreSQL. JWT auth
+(access + refresh tokens), RBAC permissions, Redis cache, RabbitMQ background
+workers. Python >=3.13,<4.0, Poetry for dependency management.
+
+## Auth & Permissions
+
+- Users have `direct_permissions` (list of `Permissions`) and `group`
+  (list of `PermissionsGroups`, each with its own `permissions`) —
+  many-to-many both ways.
+- Effective permissions = `direct_permissions ∪ (union of all groups' permissions)`.
+- `require_permissions(*permissions)` in `src/web/protected_routes` is a
+  FastAPI dependency factory — wraps `CurrentUserService.get_current_user`.
+  Call with no args (`require_permissions()`) for "just authenticated, no
+  specific permission needed".
+- Access tokens carry a `jti` claim. Logout writes `revoked_access_token:{jti}`
+  to Redis with TTL = remaining token lifetime — `get_current_user` checks
+  this key before anything else.
+- `secure` flag on refresh_token cookie is driven by `env_settings.PROD_MODE`
+  (bool) — `False` locally/tests so cookies work over plain HTTP, `True` in
+  prod.
+
+## Redis (`src/cache/`)
+
+- `RedisClient(redis.Redis)` — module-level shared singleton, subclasses
+  `redis.Redis` directly (inherits all commands, no manual wrapping needed).
+- Three uses: permissions is-cache was considered and rejected (no real DB
+  savings — `get_user_by_id` already eager-loads everything via `selectin`
+  in one call); rate limiting on login (`RateLimit.rate_limit(ip)` —
+  `INCR` + `EXPIRE` on first attempt, blocks >5/60s); access-token revoke
+  blacklist (see above).
+- Rate limit is only triggered inside `except HTTPException` on `/protected/token`
+  — i.e. only on failed logins, not successful ones (otherwise legitimate
+  repeated logins would trip it).
+
+## RabbitMQ (`src/messaging/`)
+
+- `RabbitMQClient` — shared class, lazy `connect()` (can't be async `__init__`),
+  holds one `connection` + one `channel`, `get_channel()` ensures setup.
+  `connect()` retries `connect_robust()` up to 5 times with exponential
+  backoff (`asyncio.sleep(2**attempt)`) before raising — needed because
+  when running the app locally (outside Docker Compose) right after
+  `docker compose up rabbitmq`, the broker's AMQP listener isn't
+  immediately ready and resets the connection mid-handshake
+  (`ConnectionResetError`). Compose's own `depends_on: condition:
+  service_healthy` only helps when the app itself also runs as a Compose
+  service — it does nothing when the app is started on the host.
+- **Topology is centralized, not declared ad-hoc.** `src/models/rabbitmq_models/email.py`
+  defines the whole topology as pydantic data (`Topology`/`ExchangeSpec`/`QueueSpec`,
+  exported as `email_topology`) — topic exchange `"email"`, one durable
+  quorum queue per message type (`queue_welcome_email`/`email.welcome`,
+  `queue_reset_email`/`email.reset`), each with a matching dead-letter queue.
+  `src/messaging/topology_setup.py::apply_topology(channel, topology)` is
+  the only place that actually calls `declare_exchange`/`declare_queue`/`bind`
+  against RabbitMQ. It's called once at startup — in `main.py`'s `lifespan`
+  (web) and in `daemon_run.py`'s `main()` (daemon entrypoint) — **before**
+  any producer/consumer touches the exchange/queues. `EmailProducer`/
+  `WelcomeEmailConsumer`/`ResetEmailConsumer` no longer declare or bind
+  anything themselves — they only `get_exchange("email")` /
+  `get_queue("queue_...")`, assuming `apply_topology` already ran.
+  Changing a queue's arguments in `email_topology` requires manually
+  deleting the existing queue in RabbitMQ first — `declare_queue` on an
+  already-existing queue with different arguments fails with
+  `PRECONDITION_FAILED`, it doesn't update in place.
+- **Dead-lettering**: each original queue's `x-dead-letter-exchange` points
+  at `email.dlx`, a **`direct`** exchange (not `fanout` — fanout would
+  broadcast every dead-lettered message to *all* DLQs, mixing up
+  welcome/reset failures). Each DLQ is bound to `email.dlx` with the same
+  routing key as the original queue (`email.welcome`/`email.reset`);
+  RabbitMQ preserves a message's original routing key when dead-lettering,
+  so no explicit `x-dead-letter-routing-key` override is needed — the
+  `direct` exchange alone routes each dead letter back to the correct DLQ.
+- `message.process(ignore_processed=True)` + manual `await message.nack(...)`
+  in `process_message`, not the plain auto-ack/nack that `message.process()`
+  does by default — needed because business-logic exceptions are caught
+  *inside* the block (to log them and decide retry vs. dead-letter) rather
+  than left to propagate, so `process()` itself must be told not to also
+  try to ack/nack on exit. Classification: transient errors (SMTP/network:
+  `SMTPServerDisconnected`, `SMTPConnectError`, `TimeoutError`,
+  `ConnectionRefusedError`) → `nack(requeue=True)`; everything else
+  (bad message body, `SMTPAuthenticationError`, bugs) → `nack(requeue=False)`
+  → DLQ. Note `SMTPAuthenticationError` is a known rough edge here — it's
+  a systemic config problem (bad credentials), not a per-message one, but
+  is currently DLQ'd per-message like any other permanent error rather
+  than halting the daemon with an alert.
+- Email templates: Jinja2 (`src/service/email/jinja_env.py` — one shared
+  `Environment`/`FileSystemLoader` singleton, templates in
+  `src/service/email/templates/`), inline CSS (email clients don't support
+  `<style>` reliably), `EmailMessage` with `set_content()` (plain-text
+  fallback) + `add_alternative(html, subtype="html")`.
+- Reset-password flow mirrors welcome: `ResetEmailSender`
+  (`src/service/email/email_reset.py`) renders `templates/reset.html`
+  (`{{ temp_password }}`, no longer hardcoded) the same way
+  `DaemonEmailSender` does `welcome.html`. `ResetEmailConsumer.process_message`
+  reads both `email` and `temp_password` from the message body and uses the
+  same transient/permanent classification as `WelcomeEmailConsumer`.
+  `EmailProducer.send_reset_email(email, temp_password)` takes the password
+  as a second argument now. **Still missing**: nothing in the app actually
+  calls `send_reset_email` yet — there's no password-reset route that
+  generates a `temp_password` and publishes it. Don't assume the
+  reset-password feature is reachable end-to-end until that route exists.
+
+## Logging (`src/logging/`)
+
+- All log output (HTTP endpoints, SQL, daemons) funnels through one
+  module-level `asyncio.Queue` (`log_queue` in `src/logging/logger.py`) and
+  a single `LogWriter.log_writer()` background task that drains it and
+  appends to `./logs/{type}_log_{month}_{year}.txt` — this avoids the
+  original bug of firing an unsupervised `asyncio.create_task` per log
+  line (unordered writes, lost logs if the process died before the task
+  ran). **`log_writer()` must be started explicitly wherever the process
+  entrypoint is** — it's `asyncio.create_task(writer.log_writer())` in
+  `main.py`'s `lifespan` for the web process, and the same call in
+  `daemon_run.py`'s `main()` for the daemon process. `log_queue` is
+  process-local (plain in-memory `asyncio.Queue`, not shared across
+  processes), so **every new entrypoint needs its own writer task** or its
+  logs silently queue forever and are never written (unbounded memory
+  growth, not a crash).
+- `logging.Handler` subclasses (`LoggerDB` for `sqlalchemy.engine`,
+  `LoggerDaemon` for the `"daemon"` logger) just push `(type, formatted_msg)`
+  onto `log_queue` from `emit()` — do **not** give them a custom `__init__`
+  that doesn't call `super().__init__()`; skipping it means `self.level`/
+  `self.filters`/etc. never get set and any log call raises `AttributeError:
+  'LoggerX' object has no attribute 'level'`.
+- Two `ContextVar`s tag log lines with a correlation id without threading
+  it through every function call: `request_id_ctx` (set once per HTTP
+  request in `LoggingMiddleware.dispatch`) and `message_id_ctx` (meant to
+  be set once per RabbitMQ message in `process_message`). Only visible
+  within the same async call chain — a `ContextVar` set in an HTTP request
+  is `"-"` (the default) inside daemon code, and vice versa; they don't
+  cross the process boundary either.
+- **`src/logging/logger.py` vs `src/logging/http_logger.py` split matters
+  for Docker.** `logger.py` has zero `fastapi`/`starlette` imports —
+  intentional, because the `daemon` Poetry group (and therefore the daemon
+  Docker image) never installs `fastapi`. `http_logger.py` holds
+  `LoggingMiddleware`/`ProcessingTimeMiddleware` (the only things that
+  actually need FastAPI/Starlette) and is imported only from `main.py`.
+  `src/logging/__init__.py` imports only from `logger.py`. **Never import
+  `src.logging.http_logger` from anything that runs in the daemon
+  process** (`consumers.py`, `email_welcome.py`, `daemon_run.py`, etc.) —
+  it would drag in `fastapi`, which raises `ModuleNotFoundError` in the
+  daemon container.
+- Plain `logger.exception(...)` must only be called from inside an
+  `except` block — it pulls the active exception via `sys.exc_info()` to
+  attach a traceback. Called outside `except` (e.g. for a routine "message
+  received" log line), it still runs but appends a literal `NoneType: None`
+  instead of a traceback, since there's no active exception to format.
+
+## Daemons / workers (`src/daemons/`)
+
+- `BaseDaemon` ABC (`name` + async `run()`), one subclass per consumer
+  (`WelcomeEmailDaemon`, `ResetEmailDaemon`, more to come — e.g. reports).
+- `DAEMONS` registry dict maps string name → daemon class.
+- `daemon_run.py` (project root) is the single entrypoint: `python
+  daemon_run.py <name>` runs one daemon, `python daemon_run.py --all` reads
+  `configs/daemons.json` (`{"daemons": [...]}`) and runs all enabled ones
+  concurrently via `asyncio.gather`. `main()` also applies the RabbitMQ
+  topology (`apply_topology`) and starts the log writer task before
+  dispatching to either mode, inside a `try`/`finally` so both the
+  single-daemon and `--all` paths cancel the writer task on the way out.
+- Each daemon runs as its own Docker service/container (`command: ["python",
+  "daemon_run.py", "<name>"]`), same pattern as the `migration` service.
+- `daemons.json` is read with a plain Pydantic `BaseModel` + manual
+  `json.load`, NOT `pydantic-settings` `json_file` — that requires wiring
+  `settings_customise_sources` manually in this pydantic-settings version
+  and isn't worth the complexity here.
+
+## Docker / Poetry groups
+
+- `pyproject.toml` uses PEP 621 `[project.dependencies]` for shared deps
+  (sqlalchemy, redis, aio-pika, pydantic, bcrypt, jose, aiofiles, asyncpg,
+  psycopg2-binary, alembic, greenlet).
+- `web` group: fastapi, uvicorn, gunicorn, python-multipart — only needed
+  by the API server.
+- `daemon` group: worker-only deps — `aiosmtpd`, `jinja2` (email sending
+  and templating). Must **not** gain a `fastapi`/`starlette` dependency;
+  see the `src/logging/logger.py` vs `http_logger.py` split above for why
+  that boundary is enforced deliberately.
+- `dev` group: pytest stack, allure, httpie, requests-async.
+- `claude` group: `graphifyy` (the `/graphify` Claude Code skill) — dev
+  tooling only, never referenced by any Dockerfile stage, install with
+  `poetry install --with claude` when needed locally.
+- Dockerfile has parallel builder→final stage pairs: `builder`→`prod`
+  (installs `main,web`) and `worker-builder`→`worker` (installs
+  `main,daemon`). Same base pattern: venv builder stage copies
+  `/opt/venv` into a clean final stage, poetry itself is uninstalled
+  after install to keep the final image lean.
+- Alembic runs against a **separate sync engine** (`asyncpg` swapped out,
+  psycopg2 used instead) — async SQLAlchemy engine can't drive Alembic
+  directly without the `run_sync` bridge, and a dedicated sync engine is
+  simpler than that bridge.
+- `DB_HOST` differs between contexts: `psql` (Docker service name) for
+  containers talking to each other, `localhost` for anything run on the
+  host (e.g. local `alembic revision --autogenerate`). Compose services
+  override `DB_HOST` via `environment:`; the `.env` file's own default is
+  for host-side runs.
+
+## Codebase knowledge graph (graphify)
+
+- `/graphify` (Claude Code skill, `graphifyy` package in the `claude`
+  Poetry group) builds a navigable knowledge graph of this repo into
+  `graphify-out/` (`graph.html`, `GRAPH_REPORT.md`, `graph.json`) —
+  gitignored, regenerable, never commit it.
+- Its own interpreter/venv detection defaults to `uv tool`/pipx-style
+  installs; **this project has neither** — `graphifyy` is installed
+  straight into the project's own `.venv` via Poetry, so point graphify
+  at `.venv/bin/python3` directly rather than letting it search for `uv`.
+- The sandbox's blanket `**/.env`/`**/.env.*` read-deny blocks graphify
+  from reading `configs/.env.example` too (not just the real `.env`) —
+  it shows up as `skipped_sensitive` in detection. This is a sandbox-level
+  block, not graphify's own sensitive-file heuristic; a real `.env` would
+  be excluded by graphify anyway, but `.env.example` (no real secrets)
+  would otherwise be safe to include if the sandbox allowed reading it.
+- A `GRAPH HEALTH WARNING` (dangling-endpoint edges, collapsed edges) on
+  a fresh build most likely means the AST extractor's node-ID format
+  changed since a previous partial run — re-run with `graphify extract
+  --force` if it persists across rebuilds; a one-off warning on first
+  build isn't necessarily a problem.
+
+## Testing (`tests/unit`, `tests/integrated`, `tests/e2e`)
+
+- **Recurring root cause of "different event loop" / `MissingGreenlet`-style
+  errors**: prod code uses module-level singletons (`engine`, `redis_client`)
+  created once at import time and reused for the app's whole lifetime — this
+  is correct for prod (one event loop, whole uptime) but breaks under
+  pytest-asyncio's default `function`-scoped event loop (a new loop per
+  test, but the singleton's connections stay bound to the *first* loop).
+  Fix: test fixtures create a **fresh** `engine`/`RedisClient` per test and
+  monkeypatch or inject them in place of the global singleton, then dispose
+  on teardown — not a global `session`-scoped event loop (that would mask
+  real isolation bugs).
+- e2e `MySession` must subclass `httpx.AsyncClient` (not `requests_async.
+  AsyncSession` — that library silently drops cookies between requests,
+  which broke refresh-token-cookie-dependent tests like logout).
+- `test_user_fixture` is `indirect=True` parametrized with
+  `(direct_permissions, group)` tuples.
+- `tests/unit/test_consumers.py` covers `RabbitMQClient`/`WelcomeEmailConsumer`/
+  `ResetEmailConsumer` entirely with mocks — no real broker involved.
+  Pattern: `monkeypatch.setattr(rabbitmq_client_module.aio_pika, "connect_robust", ...)`
+  patches the module attribute that `connect()` looks up at call time (not
+  the `rabbitmq_client` singleton's method — that's a bound method, it has
+  no attribute of its own to patch). `aio_pika.connect_robust`/`asyncio.sleep`
+  must both be mocked when testing the retry loop, or the test really
+  sleeps `2**attempt` seconds between attempts. `message.process(...)` is an
+  async context manager, not a plain awaitable — mocking it needs a
+  `MagicMock` with `__aenter__`/`__aexit__` set to `AsyncMock`s (see
+  `make_fake_message()` in that file), not just `AsyncMock()`. When
+  asserting on what a mocked async method returned, compare against
+  `mock.return_value` (or a variable captured before assigning it), never
+  against the mock itself — `some_mock is some_mock.return_value` is never
+  true, they're two different objects.

 Layers are connected top to bottom: `web → service → database → models`.
 
+## Background workers (RabbitMQ)
+
+Email sending (welcome / password-reset) runs as separate daemon processes,
+decoupled from the web API via a RabbitMQ topic exchange:
+
+```
+main.py / daemon_run.py → apply_topology() → RabbitMQ ("email" exchange)
+                                                   ├── queue_welcome_email → WelcomeEmailConsumer
+                                                   └── queue_reset_email  → ResetEmailConsumer
+```
+
+Each queue has a matching dead-letter queue for messages that fail
+permanently (bad data, non-retryable errors) instead of retrying forever.
+Run a worker locally with:
+
+```bash
+python daemon_run.py welcome_email   # single daemon
+python daemon_run.py --all           # all daemons enabled in configs/daemons.json
+```

 Uses pytest, pytest-asyncio, pytest-cov, pytest-mock, allure-pytest.
 
+### Allure report
+
+`make allure` needs the Allure **command-line tool** (Java-based, not a pip
+package) — `allure-pytest` only writes raw result files, the CLI turns them
+into an HTML report.
+
+1. Download Allure **2.44.0** from
+   [github.com/allure-framework/allure2/releases](https://github.com/allure-framework/allure2/releases).
+2. Extract it into `.venv/allure-2.44.0/` so that `.venv/allure-2.44.0/bin/allure`
+   exists — this matches the `ALLURE` variable already set in `makefile`.
+3. If you install it somewhere else (or on Windows), update the `ALLURE`
+   variable at the top of `makefile` to point to your actual `allure`
+   binary path — the Windows path is already there, commented out.
+
+```bash
+make test     # runs pytest, writes results to tests/allure-results/reports
+make allure   # builds tests/allure-results/html/index.html from those results
+```
+
 ## Installation
 
+Requires Poetry itself to be installed first (it's a global tool, not a
+project dependency). Recommended via [pipx](https://pipx.pypa.io/):
+
+```bash
+pipx install poetry
+```
+
+or via the official installer:
+
+```bash
+curl -sSL https://install.python-poetry.org | python3 -
+```
+
+Then install the project dependencies:
+
 ```bash
 poetry install
 ```
 
+## Codebase knowledge graph (graphify)
+
+The repo can be explored as a navigable knowledge graph via the
+[graphify](https://github.com/safishamsi/graphify) Claude Code skill —
+useful for onboarding or tracing how a change ripples across modules.
+It lives in its own Poetry group (`claude`) so it's never installed in
+`web`/`daemon`/prod images:
+
+```bash
+poetry install --with claude
+```
+
+Then, inside a Claude Code session in this repo, run:
+
+```text
+/graphify
+```
+
+This builds `graphify-out/graph.html` (open directly in a browser),
+`graphify-out/GRAPH_REPORT.md` (god nodes, surprising cross-module
+connections, suggested questions), and `graphify-out/graph.json` (raw
+graph data). Ask follow-up questions about the codebase directly — once
+`graphify-out/graph.json` exists, Claude answers from the graph instead
+of rebuilding it. `graphify-out/` is gitignored: it's regenerable local
+output, not part of the codebase.
