+A rule targets a **genre**, a **series**, or a single **item**; the most specific
+matching rule wins (item > series > genre). Setting a rule for a target that
+already has one replaces it, so nothing can be both prioritised and ignored.

+naturally spreads work across the backlog without needing server-side task
+tracking; an empty array means there's nothing left to do (or every remaining
+item is a virtual/missing-path item that JRay can't process).
+
+**Prioritise/ignore rules apply here.** Items covered by an **ignore** rule are
+never returned. Items covered by a **prioritise** rule are returned ahead of
+un-prioritised items (still randomised within each tier). See
+[Prioritise / ignore rules](#prioritise--ignore-rules) below. Rules only affect
+this work-discovery endpoint — they never change the overlay or the read
+endpoints, so an item you ignore for extraction still shows its overlay if truth
+data happens to exist for it.
+
+## Prioritise / ignore rules
+
+Admins can steer the work-discovery queue with a small set of **rules**. Each
+rule targets a **genre**, a **series**, or a single **item**, and either
+**prioritises** (moves matching items to the front of `Tasks/Pending`) or
+**ignores** them (hides them from `Tasks/Pending` entirely). This is how you
+say "never extract anime", "process this series first", or "skip this one
+movie".
+
+Rule resolution for an item picks the **most specific** matching scope:
+`Item` overrides `Series`, which overrides `Genre`. A rule is uniquely keyed by
+its scope + value, and setting a rule for an existing scope+value **replaces**
+it — so a single target can never be both prioritised and ignored. (An item can
+still be pulled in two directions across scopes, e.g. a prioritised series in an
+ignored genre; specificity resolves that — the series rule wins.)
+
+Rules are persisted to `policy.json` under the plugin's configuration directory.
+A rule object:
+
+```json
+{ "scope": "Genre", "value": "Anime", "action": "Ignore", "label": "Anime" }
+```
+
+- `scope`: `"Genre"`, `"Series"`, or `"Item"`.
+- `value`: a genre name (for `Genre`), a series id GUID (for `Series`), or an
+  item id GUID (for `Item`). Genre matching is case-insensitive.
+- `action`: `"Prioritise"` or `"Ignore"`.
+- `label`: optional human-readable label shown in the config UI (informational).
+
+All endpoints below require an **Administrator** API key.
+
+### `GET /Plugins/JRay/Policy/Rules`
+
+Returns all configured rules as a JSON array of rule objects.
+
+### `PUT /Plugins/JRay/Policy/Rules`
+
+Adds or replaces a rule (body is a single rule object). Replaces any existing
+rule with the same `scope` + `value`. Returns `204`, or `400` if `value` is
+empty.
+
+### `DELETE /Plugins/JRay/Policy/Rules?scope={scope}&value={value}`
+
+Removes the rule matching `scope` + `value`. Idempotent, always returns `204`.
+
+## Coverage overview
+
+### `GET /Plugins/JRay/Coverage`
+
+Returns how much of the library has truth data, overall and broken down by
+media type (Film vs TV) and by genre. Requires an **Administrator** API key.
+
+```json
+{
+  "total":  { "total": 1200, "covered": 300, "pending": 850, "prioritised": 40, "ignored": 50 },
+  "by_media_type": [
+    { "label": "Film", "counts": { "total": 400, "covered": 200, "pending": 190, "prioritised": 10, "ignored": 10 } },
+    { "label": "TV",   "counts": { "total": 800, "covered": 100, "pending": 660, "prioritised": 30, "ignored": 40 } }
+  ],
+  "by_genre": [
+    { "label": "Anime", "counts": { "total": 120, "covered": 0, "pending": 0, "prioritised": 0, "ignored": 120 } }
+  ]
+}
+```
+
+Each `counts` object buckets items as: `covered` (has truth data),
+`pending` (needs processing and not ignored; `prioritised` is the subset of
+`pending` under a prioritise rule), and `ignored` (excluded by an ignore rule).
+`total` is the sum. A useful "percent done" is `covered / (total - ignored)`,
+so ignoring a genre or series does **not** drag the percentage down — ignored
+items are treated as intentionally out of scope.
+
+An item counts toward every genre it carries, so genre rows can overlap and
+their totals need not sum to the library total.
+
+### Pickers for the config UI
+
+Three helper endpoints populate the rule editor's dropdowns (all require an
+**Administrator** API key, all return `[{ "value": ..., "label": ... }]`):
+
+- `GET /Plugins/JRay/Coverage/Genres` — distinct genres present on movies/episodes.
+- `GET /Plugins/JRay/Coverage/Series` — series in the library (`value` is the series id).
+- `GET /Plugins/JRay/Coverage/Items?search={term}&limit={n}` — movies/episodes
+  whose name matches `term` (`value` is the item id; `limit` default 25, max
+  100). An empty/absent `search` returns `[]`.
