+Guidance for working in this repo. Read alongside `README.md` (user-facing setup
+for the original FastAPI skeleton this app was built from).
 
 ## What this is
 
-A FastAPI skeleton serving **both** a JSON API (`/api/*`) and server-rendered
+**Fitguide**: a parts-compatibility guide for Armament scopes and accessories,
-HTML via **Jinja2 + HTMX** (`/`, `/admin/*`). Async SQLAlchemy 2.0 ORM, JWT auth

+server-rendered HTML via **Jinja2 + HTMX** (`/`, `/scopes`, `/admin/*`). Async
+SQLAlchemy 2.0 ORM, JWT auth with refresh-token revocation (plus optional LDAP
+direct-bind login), and RBAC (users → roles → permissions). The domain layer on
+top of the skeleton tracks parts, their attachment points, and which parts fit
+together — see "Domain model" below.
 
 ## Commands
 
 ```bash
 uv sync --extra dev                    # install (incl. dev tools)
+uv run alembic upgrade head            # apply migrations
 uv run python -m scripts.seed          # seed perms/roles/superuser (idempotent)
 uv run uvicorn app.main:app --reload   # dev server on :8000
 uv run pytest                          # tests (in-memory SQLite)
+uv run pytest tests/test_foo.py::test_bar   # single test
 uv run ruff check . [--fix]            # lint
-uv run alembic upgrade head            # apply migrations
+uv run black .                         # format (ruff does not format here)
 uv run alembic revision --autogenerate -m "msg"   # new migration after model changes
 docker compose up --build              # app + Postgres, auto-seeded
 ```
 
+`Makefile` wraps the common ones (`make sync|seed|dev|test|fmt|migrate`).
+`make clean` deletes the local `app.db`, re-migrates, and reseeds — the quick
+way to get a clean dev database. `make seed` runs `alembic upgrade head` before
+seeding, i.e. day-to-day dev relies on migrations, not just
+`AUTO_CREATE_TABLES` (see "Database").

 token logic in `app/services/auth.py`. Keep route handlers thin; put DB logic in
 `crud/`, not in routers.
 
+`app/api/` is one router module per resource, all mounted under `/api` by
+`app/api/router.py`. `app/web/` is organized differently: `pages.py` (dashboard/
+login), `scopes.py` (the public-facing `/scopes` fit guide), and **`admin.py`**
+— a single ~3000-line router covering every admin screen (users, roles, part
+taxonomy tables, imported parts, augmented parts + detail + nested attachment
+points/fits, audit log, etc.), organized into `# --- Section ---` banner
+comments per resource rather than split into files. When adding an admin screen,
+follow the existing banner-section convention there rather than starting a new
+web router module.
+
+## Domain model
+
+The business domain, independent of the auth/RBAC skeleton:
+
+- **`AugmentedPart`** (`augmented_parts`) is the generic "part" entity — a
+  scope, flip cover, ARD, polarizer, adapter ring, etc. — distinguished by
+  `PartType`/`SubPartType`, with `PartColour`, `Manufacturer`, and an optional
+  `ScopeModel`. "Scope" is just one `PartType` value (see `SCOPE_TYPE_NAME` in
+  `app/services/scope_guide.py`), not a separate table.
+- **`ScopeInfo`** is a 1:1 extension of `AugmentedPart` (magnification,
+  objective thread, model suffix) populated only for scope-type parts.
+- **`AttachmentPoint`** belongs to one `AugmentedPart`, is named via
+  `AttachmentPointName` (e.g. "Ocular", "Objective"), and connects via
+  *exactly one* of `IsoThread` / `UncThread` / `ClampConnection` /
+  `StaticConnection` — that "exactly one" invariant is enforced in the app
+  layer (CRUD/API validation), not by a DB constraint.
+- **`Fit`** (`app/models/fit.py`) pairs two `AttachmentPoint`s (canonical
+  ordering enforced in `app/crud/fit.py` so a pair only ever has one row),
+  labeled `possible` / `exact` / `none`, with threaded `FitNote`s.
+  `app/services/fit_matching.py` computes `possible` fits automatically
+  (matching ISO/UNC thread specs exactly, or a static connection's dimension
+  falling inside a clamp connection's range); `exact`/`none` are user-asserted
+  and never touched by the algorithm.
+- **`ImportedPart`** (`imported_parts`, PK is the string `InventoryID` — not an
+  int id) holds raw rows from an external inventory feed, fetched via
+  `app/services/odata.py` (OData v4, paginated). `app/services/
+  augmented_part_sync.py` reconciles these into `AugmentedPart` +
+  `AttachmentPoint` rows: infers `PartType` by substring match on the
+  description, parses `TBXThreadAttribute` against ISO/UNC regexes (falling
+  back to an OD-derived `StaticConnection`), and prunes `AugmentedPart`s whose
+  backing `ImportedPart`s have disappeared.
+- **`app/services/scope_import.py`** is a separate, manually-triggered bulk
+  importer: reads an uploaded `.xlsx` of third-party scopes, upserting by
+  `product_number` (→ `AugmentedPart.sku`) and creating `ScopeModel`,
+  `ScopeInfo`, up to three `AttachmentPoint`s, and up to two `Fit`s per row
+  (see the module docstring for the full column mapping).
+- **`app/services/scope_guide.py`** assembles the `/scopes` page: one row per
+  Scope-type `AugmentedPart`, one column per other `PartType`, each cell
+  listing parts of that type with a recorded `Fit`.
+
 ## Conventions that matter
 
 - **Everything async.** Engine, sessions, CRUD, routes, tests. Use `await`; never
   add a sync DB call. `get_db` (in `app/core/database.py`) yields the request session.
-- **Relationships use `lazy="selectin"`** (`User.roles`, `Role.permissions`) so
+- **Relationships use `lazy="selectin"`** (`User.roles`, `Role.permissions`,
-  attributes are safe to read after the session closes — required under async.
+  `AttachmentPoint.iso_thread`, etc.) so attributes are safe to read after the
-  Preserve this when adding relationships that templates/schemas read.
+  session closes — required under async. Preserve this when adding relationships
+  that templates/schemas read.
 - **Config** is `app/core/config.py` (`pydantic-settings`). Add new settings there;
   they're auto-read from env vars (uppercased field name) or `.env`. Env wins.
 - **RBAC**: guard API routes with `Depends(require_permission("resource:action"))`;
   guard web routes with `web_require(...)` in `app/web/admin.py`. Superusers bypass
   all checks (`User.is_superuser` / `User.has_permission`). Add new permission
   strings to `scripts/seed.py`'s `PERMISSIONS`/`ROLES`.
+- **HTMX UI-level write gating**: on top of route-level RBAC, pages that mix
+  read-only and read-write viewers (e.g. `augmented_part_detail.html`'s Fits and
+  Attachment Points sections) compute a `can_write_<thing>` bool from the
+  current user's permissions and wrap add/edit/delete controls in
+  `{% if can_write_<thing> %}` in the template, so read-only users see data but
+  not controls they'd get a 403 on. The route-level `web_require(...)` check
+  remains the real security boundary; the template flag is only for UX.
 - **Auth, two transports**: API uses `Authorization: Bearer`; the HTMX UI uses an
   httpOnly cookie (`settings.cookie_name`). `app/deps.py` reads both. Web auth
-  failures raise `NotAuthenticated`, handled in `main.py` as a redirect to `/login`.
+  failures raise `NotAuthenticated`, handled in `main.py` as a redirect to `/login`
+  (preserving the original path as `?next=`).
 - **Refresh tokens** are stored server-side (hash + `jti` + `revoked`) in the
   `refresh_tokens` table. `services/auth.rotate_refresh_token` revokes-then-reissues.
   Note: JWT payload `exp` is a tz-aware `datetime` (PyJWT only epoch-encodes inside
   the token) — pass it straight to the model, don't `fromtimestamp` it.
+- **LDAP login** (`app/services/ldap.py`) is optional (`settings.ldap_enabled`),
+  direct-bind, and just-in-time provisions a local `User` on first successful
+  login. `ldap3` is sync, so its calls run via `run_in_threadpool`.
 
 ## Database
 
 One `DATABASE_URL` drives SQLite (`sqlite+aiosqlite://`, the default) or Postgres
 (`postgresql+asyncpg://`). `AUTO_CREATE_TABLES=true` calls `Base.metadata.create_all`
-on startup for dev convenience; production should use Alembic instead. `init_db()`
+on startup for dev convenience, but the day-to-day `make seed`/`make clean` flow
-imports `app.models` inside the function to avoid a circular import.
+runs `alembic upgrade head` first — treat Alembic migrations as the source of
+truth and keep them in sync with model changes. `init_db()` imports `app.models`
+inside the function to avoid a circular import.
 
 ## Tests
 
 `tests/conftest.py` builds an in-memory SQLite engine with `StaticPool`, creates
 tables, and overrides `get_db`. Fixtures: `client` (httpx ASGI), `seeded`
-(perms+roles), `make_user`. `asyncio_mode = "auto"` — write `async def test_*`
+(perms+roles from `scripts.seed.PERMISSIONS`/`ROLES`), `make_user`, and
-without decorators.
+`db_sessionmaker` (used directly in tests to seed domain rows — models, fits,
+attachment points — beyond what `seeded`/`make_user` cover). `asyncio_mode =
+"auto"` — write `async def test_*` without decorators.
