+# Dashboard tables
+
+How every data table on the dashboard is laid out, and the rules a new table
+must follow so it never grows a horizontal scrollbar on a desktop screen.
+Everything here is plain CSS in `src/web/tailwind.css` plus four cell classes;
+there is no table library and no JavaScript involved.
+
+## The problem this solves
+
+A table used to be `min-width: max-content` inside a `.scroll-x` wrapper, and
+most cells were `white-space: nowrap`. Any table whose natural width exceeded
+the page column (80rem, ~1355px at the site's 110% scale) became a horizontal
+scroller, even on a 2560px monitor, and the columns that mattered were hidden
+behind the scrollbar. Wrapping columns were squeezed to their minimum while the
+nowrap ones kept everything.
+
+## The three rules
+
+1. **Tables get the whole viewport, everything else keeps the page column.**
+   `.dashboard` is a CSS grid with two named column spans: `content` (at most
+   80rem minus the page gutters, exactly what the header uses) and `wide` (the
+   viewport minus the same gutters). Every direct child sits in `content`; a
+   direct-child `.scroll-x` sits in `wide`. The table inside a wide wrapper is
+   `width: auto` (shrink-to-fit) with `min-width` equal to the content column
+   and `max-width: 100%`, centred. A table that fits the page column therefore
+   looks exactly as before; a table that needs more grows, centred, up to the
+   viewport edge; the page itself never scrolls sideways.
+
+2. **Columns wrap before the table scrolls.** The `min-width: max-content` rule
+   is gone. A table shrinks by wrapping its text columns down to their floors,
+   and only when the floors alone no longer fit (phones, mostly) does the
+   `.scroll-x` wrapper scroll. Headers always wrap.
+
+3. **A cell declares what it holds, and nothing else decides its width.**
+   There are exactly four cell classes:
+
+   | class        | use it for                                                     | behaviour                                                              |
+   | ------------ | -------------------------------------------------------------- | ---------------------------------------------------------------------- |
+   | *(none)*     | short prose, names, tokens, badges and badge lists             | wraps at spaces (a `.badge` is nowrap on its own, so lists wrap between badges) |
+   | `num`        | numbers, money, counts                                         | right-aligned tabular figures; `td.num` never wraps, `th.num` may      |
+   | `cell-tight` | timestamps, dates, ids, a single short token that must not split | `white-space: nowrap`. Nothing longer than ~20 characters              |
+   | `cell-wrap`  | titles, URLs, notes, messages, anything free-form              | floor 10rem, ceiling 32rem, `overflow-wrap: anywhere`                  |
+
+   Anything long that must not wrap gets an inner block with a Tailwind clamp
+   (`<div class="line-clamp-2" title="…">`) inside a `cell-wrap` cell; the cell
+   ceiling bounds the column, the clamp bounds the row height. Do not put
+   `truncate`/`line-clamp-*` on a `td` itself (a table cell cannot be a
+   `-webkit-box`), and do not use `table-fixed` on a page-level table (fixed
+   layout needs a definite width and is silently ignored with `width: auto`).
+
+## Checklist for a new table
+
+- Wrap it in `<div class="scroll-x">` and make that wrapper a **direct child** of `<section class="dashboard">` if the
+  table has more than a handful of columns. Tables inside `.card`, `.cards` or
+  `details` stay inside their box and just wrap/scroll there.
+- Let the page scroll. A table that is the page's feature (paginated lists,
+  anything that is the last thing on the page) shows every row at full height;
+  a scrolling island inside a scrolling page just fights the wheel. Add `tall`
+  (70vh cap, own scrollbar) only when the table is a side feature with real
+  content below it, as the profile page's version history is.
+- Give every `td` one of the four classes above according to its content.
+  When in doubt, leave it unclassed: wrapping is the safe default.
+- Never `cell-tight` a name, a title, a reason sentence or a free-text field.
+- Check the page at 390, 1280 and 2560px. At 1440 and above the wrapper's
+  `scrollWidth` must equal its `clientWidth`; at 390 a wide table is allowed to
+  scroll. A table's floor is the sum of its nowrap columns plus 10rem per
+  `cell-wrap` column: the 13-column articles table bottoms out near 1270px, so
+  it still scrolls a little on a 1280px viewport. Tables inside a `.card`
+  cannot grow past the card (20rem minimum), so a card table with more than
+  four numeric columns (run page: provider usage) scrolls inside its card at
+  1280px; move such a table to page level if that matters.
+
+## Measuring
+
+`docs/plans/briefs/dashboard-tables/measure.mjs` logs in as the dev-seed admin,
+visits every dashboard page at several widths and prints, per page, whether the
+document overflows and which table wrappers scroll. Run it against a seeded
+dev server (`cargo run --example seed_dev_db -- ./dev`) before and after a CSS
+change; the "scrolling" count for widths ≥ 1280 should be zero.

+# "Read in BookOrbit" link on the issue page
+
+**Date:** 2026-09-05
+**Repository:** `thallada/the-daily-epub`
+**Status:** small implementation plan, ready to execute
+**Builds on:** `docs/plans/2026-09-03-web-dashboard.md` (the signed-in issue page this adds a button to)
+
+Written for a fresh implementation agent. Every fact about BookOrbit below was verified on 2026-09-05 against its source (`github.com/bookorbit/bookorbit`, `HEAD`) and against the live instance on this host. Do not re-derive them; do re-check anything marked *assumption*.
+
+---
+
+## 1. Goal
+
+On the signed-in issue page (`src/web/templates/issue_full.html`), next to the existing **Download EPUB / X4 EPUB / XTC** buttons, add a **Read in BookOrbit** button that opens the *normal* (Standard) edition of that issue in BookOrbit's in-browser EPUB reader at `https://bookorbit.hallada.net`. The operator reads on desktop through this link instead of downloading.
+
+Out of scope: the X4 edition, the public (anonymous) issue page, the OPDS feed, the EPUB itself.
+
+## 2. Verified facts
+
+### About this repo
+
+- The pipeline does **not** upload to BookOrbit. `publish::publish_issue` atomically copies both EPUB editions into `publish.epub_dir` (`/home/thallada/bookorbit/books/daily-epub` on the host); BookOrbit's *watched folder* scanner picks them up later. Nothing in the run ever learns a BookOrbit id.
+- BookOrbit runs on the same host as Docker (`~/bookorbit/docker-compose.yml`): app container `bookorbit-app` published on `127.0.0.1:3498`, Postgres in `bookorbit-db` with **no published port**, and the `daily-epub` service user has no Docker socket access. Reading BookOrbit's database directly is therefore not an option.
+- Issue titles: `Issue::title()` is `The Daily EPUB — <date>` (em dash), and `title_for(Edition::Standard)` is that exact string while `title_for(Edition::X4)` appends ` (X4)` (`src/types.rs` ~531–544). Filenames use a hyphen instead: `publish::issue_filename(date, edition, "epub")` → `The Daily EPUB - <date>.epub` / `... (X4).epub`.
+- The signed-in issue view is built in `src/web/issue.rs`: `IssueView` (line ~33) carries `downloads: Vec<Download>`, assembled around line 258 from the `issues` row (`row.epub_path`, `row.x4_path`, `row.xtc_path`). The template renders them at `src/web/templates/issue_full.html:6` as `<a class="btn" href="{{ download.href }}">Download …</a>`.
+- Signed-in issue routes live in the `full_issues` router in `src/web/mod.rs` (~line 659: `/issues/{date}/articles/{article_id}`, `/issues/{date}/world`, `/issues/{date}/behind`, behind `login_required!` and `map_forbidden`); public routes (`/issues`, `/issues/{date}`) are on the root router ~line 682. Put the new route in **`full_issues`**.
+- `issues` table (`migrations/0001_init.sql:70`): `date TEXT PK, issue_number, generated_at, epub_path, x4_path, xtc_path, front_page_html, report_json` (+ `issue_json` added later). Migrations run via `sqlx::migrate!("./migrations")` (`src/db.rs:24`); latest file is `0004_web.sql`, so the new one is `0005_bookorbit.sql`. `Db::issue_by_date(date) -> Option<IssueRow>` is at `src/db.rs:537`; `upsert_issue` at `:496` (do not touch it, ids are resolved lazily, see §3).
+- Config: sections are `#[serde(deny_unknown_fields, default)]` structs hung off `Config` (`src/config.rs:82–85`, e.g. `pub server: ServerConfig`), with `Default` impls. Env overrides are `DAILY_EPUB_<SECTION>__<KEY>`. `config.example.toml` documents every key; the README has a configuration table (~line 350).
+- The settings dashboard (`src/web/dashboard/settings.rs`) has a **hardcoded section registry** (`const` list around line 248–259 ending `"publish", "xtc", "server", "miniflux"`), a secret-field list (`("server.basic_auth_pass", FieldKind::Secret)` ~line 219, plus `SECRET_SUFFIXES` at ~223), per-key help text (~line 360), and a test asserting the section list (~line 1683). A new section must be added to all of these or the settings page/test breaks.
+- Shared HTTP client: `crate::http::build_client(timeout)` (`src/http.rs:14`), rustls + gzip, no cookies. reqwest 0.13 with the `query` and `json` features is already a dependency; **no XML parser is in the tree** — the OPDS response is tiny and regular, so either add `quick-xml` or match with a small hand parser (see §4).
+
+### About BookOrbit
+
+- Web reader route (client router, `client/src/router/index.ts`): **`/read/:bookId/:fileId`**. Both ids are required numeric integers. Book detail page is `/book/:bookId`.
+- An unauthenticated visit to `/read/...` serves the SPA shell (200) and the client auth guard redirects to `/login?redirect=<fullPath>`, returning to the reader after sign-in. So the link can point straight at the reader.
+- OPDS (server `server/src/modules/opds/opds.service.ts`, `BASE = '/api/v1/opds'`):
+  - Auth is **HTTP Basic** against a dedicated *OPDS user* created in BookOrbit's settings (separate static credentials, not the web login). Verified live: `GET http://127.0.0.1:3498/api/v1/opds/catalog?q=Daily` → `401`, `www-authenticate: Basic realm="bookorbit OPDS"`.
+  - Search: `GET /api/v1/opds/catalog?q=<terms>` (Atom acquisition feed; server-side `ILIKE` on title, accent-insensitive). Paged with `?page=N`.
+  - Each `<entry>` contains `<title>…</title>`, `<id>urn:bookorbit:book:<bookId></id>`, and one acquisition link per file:
+    `<link rel="http://opds-spec.org/acquisition" href="/api/v1/opds/<bookId>/download?fileId=<fileId>" type="application/epub+zip" title="EPUB"/>`.
+    **That href carries both numbers the reader URL needs.** Each daily issue edition is its own book with a single EPUB file.
+- The JSON API (`/api/v1/books/search?q=`, `/api/v1/books/:id` with `files[].id`) exists too but needs a JWT from `/auth/login` (5/min throttle, refresh cookie). Not worth it; OPDS is enough.
+- Book titles come from the EPUB `dc:title`, so the Standard edition is titled `The Daily EPUB — 2026-09-05` and the X4 one `The Daily EPUB — 2026-09-05 (X4)`. *Assumption:* BookOrbit's metadata fetcher has not renamed them; the matcher in §4 tolerates a fallback to the filename form.
+
+## 3. Design decisions (settled)
+
+| Topic | Decision | Why |
+|---|---|---|
+| Where ids are resolved | **Lazily, on click**, by a new redirect route `GET /issues/{date}/read` in the signed-in router. | BookOrbit indexes the folder some time after the run ends, so the id does not exist at publish time. Rendering the issue page must stay free of cross-service calls (see perf work in `main` 17a8804 and earlier). |
+| Caching | Two nullable columns on `issues`: `bookorbit_book_id INTEGER`, `bookorbit_file_id INTEGER`. Filled on first successful lookup; later clicks redirect from the cache with no network call. | One OPDS call per issue, ever. |
+| Stale cache | If BookOrbit answers the *reader page*, we can't tell from a redirect. Instead: `GET /issues/{date}/read?refresh=1` clears the cached ids and re-resolves. Expose it as a tiny "wrong book?" link only if trivial; otherwise document the query param in the README. | Books can be deleted/re-added in BookOrbit, changing ids. |
+| Not indexed yet | Route returns **503** with the existing error template (`src/web/templates/error.html`), message "BookOrbit has not indexed this issue yet. Try again in a minute." Nothing cached. | Honest, cheap, retry-friendly. |
+| Which edition | Standard only. The entry whose `<title>` equals `issue.title_for(Edition::Standard)` **exactly**; entries ending in ` (X4)` are never chosen. | The whole point is desktop reading. |
+| Auth to BookOrbit | HTTP Basic with an OPDS user's credentials from config. | Static creds, no token lifecycle; same mechanism KOReader already uses. |
+| Feature flag | Whole feature off unless `[bookorbit] enabled = true` **and** the three credentials/URL keys are set. Button and route are absent when off. | Repo stays usable without BookOrbit, as today. |
+| Link target | `<public_url>/read/<bookId>/<fileId>`, `public_url` from config (`https://bookorbit.hallada.net`), opened with `target="_blank" rel="noopener"`. | BookOrbit's own login redirect handles the signed-out case. |
+
+## 4. Implementation steps
+
+1. **Config** (`src/config.rs`, `config.example.toml`, README table):
+   ```toml
+   [bookorbit]
+   enabled = false
+   public_url = "https://bookorbit.hallada.net"   # what the browser opens
+   api_url = "http://127.0.0.1:3498"               # where the server talks OPDS; same host
+   opds_user = ""                                  # an OPDS user from BookOrbit → Settings → OPDS
+   # opds_pass: environment only (DAILY_EPUB_BOOKORBIT__OPDS_PASS)
+   ```
+   `BookorbitConfig { enabled: bool, public_url: String, api_url: String, opds_user: Option<String>, opds_pass: Option<String> }` with `deny_unknown_fields, default`. Add `pub bookorbit: BookorbitConfig` to `Config` and its `Default`. Add a `fn is_active(&self) -> bool` (enabled + user + pass non-empty). Validate URLs have no trailing slash (or trim).
+
+2. **Settings dashboard** (`src/web/dashboard/settings.rs`): add `"bookorbit"` to the section list, `("bookorbit.opds_pass", FieldKind::Secret)` (and `"opds_pass"` to `SECRET_SUFFIXES`), help text for the five keys, update the section-list test. Copy the pattern used for `server.basic_auth_pass`.
+
+3. **Migration** `migrations/0005_bookorbit.sql`:
+   ```sql
+   ALTER TABLE issues ADD COLUMN bookorbit_book_id INTEGER;
+   ALTER TABLE issues ADD COLUMN bookorbit_file_id INTEGER;
+   ```
+   Extend `IssueRow` and `issue_by_date`'s `SELECT` with the two columns; add `Db::set_bookorbit_ids(date, Option<(i64, i64)>)` (`None` clears).
+
+4. **OPDS client** — new module `src/bookorbit.rs` (~100 lines):
+   - `pub async fn find_issue(client: &reqwest::Client, cfg: &BookorbitConfig, issue_title: &str, date: Date) -> Result<Option<(i64, i64)>>`.
+   - `GET {api_url}/api/v1/opds/catalog?q={date}` with `.basic_auth(user, Some(pass))` and `Accept: application/atom+xml`. Searching by the ISO date string avoids em-dash/hyphen and ILIKE-escaping questions, and returns at most the two editions.
+   - Parse entries: split on `<entry>`…`</entry>`, take `<title>` (XML-unescape `&amp;` etc.), and the first acquisition `href` matching `^/api/v1/opds/(\d+)/download\?fileId=(\d+)$`. Choose the entry whose title equals `issue_title` exactly; if none, accept the title equal to the filename stem `The Daily EPUB - <date>` (hyphen form); never accept a title ending in `(X4)`. Prefer `quick-xml` if you'd rather not hand-roll; either is fine, keep it small and unit-tested against a fixture built from the real XML shape in §2.
+   - Map `401/403` to a clear error ("BookOrbit rejected the OPDS credentials"), connection errors to "BookOrbit unreachable". Timeout 5 s via `http::build_client`.
+   - Log at `info` on first resolution with both ids.
+
+5. **Route** `GET /issues/{date}/read` (`src/web/issue.rs`, registered in `src/web/mod.rs` next to `/issues/{date}/behind`, same session guard as the other signed-in issue routes):
+   - 404 if the feature is inactive or the issue row is missing.
+   - If `refresh=1`, clear cached ids first.
+   - Cached ids → `303 See Other` to `{public_url}/read/{book}/{file}`.
+   - Else call `bookorbit::find_issue`; on `Some`, store and redirect; on `None`, 503 with the "not indexed yet" message; on `Err`, 502 with the error text (operator-only page, so the text can be specific).
+   - Hold a `reqwest::Client` in `WebState` (`src/web/mod.rs:144`) or build one per call; per-call is acceptable at this frequency.
+
+6. **Template**: add `read_href: Option<String>` to `IssueView` (set to `/issues/{date}/read` when the feature is active and `row.epub_path` is present, i.e. only alongside a real Standard EPUB). In `issue_full.html:6`, render `<a class="btn" href="{{ href }}" target="_blank" rel="noopener">Read in BookOrbit</a>` **before** the download buttons, inside the same flex row, and keep the row visible when it is the only button.
+
+7. **Tests**: unit tests for the XML matcher (exact title, X4 skipped, hyphen fallback, no match, malformed href); a `src/web` test that the route is 404 when inactive and 303 to the right URL when ids are cached (no network). Follow `downloads_are_listed_only_while_the_files_exist` (`src/web/issue.rs:~2059`) for the fixture style.
+
+8. **Docs/ops**: README configuration table rows for `[bookorbit]`; a note under Delivery: create an OPDS user in BookOrbit (Settings → OPDS), put its name in `config.toml` and the password in `/etc/daily-epub/env` as `DAILY_EPUB_BOOKORBIT__OPDS_PASS`, restart `daily-epub.service`. No systemd change is needed: `systemd/daily-epub.service` sets only `RestrictAddressFamilies=AF_INET AF_INET6 AF_UNIX` and no `IPAddressDeny`, so loopback HTTP to port 3498 is allowed.
+
+## 5. Acceptance
+
+- With the section absent or `enabled = false`: no button, `/issues/<date>/read` → 404, all existing tests pass.
+- With valid OPDS credentials: first click on today's issue → 303 to `https://bookorbit.hallada.net/read/<n>/<m>` and the `issues` row now has both ids; second click makes no request to BookOrbit (check the journal).
+- Clicking before BookOrbit has scanned the new file → 503 "not indexed yet", nothing cached, later click succeeds.
+- The X4 edition is never the target even though it matches the same search.
+- `cargo fmt`, `cargo clippy`, `cargo test` clean.

+# Feed discovery: propose new Miniflux subscriptions from aggregator hits
+
+**Date:** 2026-09-07
+**Repository:** `thallada/the-daily-epub`
+**Status:** small implementation plan, ready to execute
+**Builds on:** `docs/plans/2026-09-03-web-dashboard.md` (the admin dashboard this adds a page to), `docs/plans/2026-09-02-personalized-curation-v2.md` (the per-article signals this reuses)
+
+Written for a fresh implementation agent. Facts about this repo were checked against `main` (`e69940f`) on 2026-09-07. Facts about the Miniflux API were checked against `https://miniflux.app/docs/api.html` the same day; anything marked *assumption* must be re-checked against the live instance before relying on it.
+
+---
+
+## 1. Goal
+
+Most of the paper's articles arrive through aggregators (Hacker News, Lobsters, Reddit, Scour), not through the author's own feed. Every such article is a lead on a feed the operator does not subscribe to yet. This feature:
+
+1. During `generate`, after articles are persisted, asks Miniflux to discover the feed(s) behind each aggregator-only article and records the ones the operator is not already subscribed to as **feed candidates**.
+2. Adds an admin dashboard page, **Feeds** (`/dashboard/feeds`), listing candidates ranked by how likely the operator is to enjoy the feed, computed **algorithmically from telemetry the pipeline already persists** (utility / preliminary blend, stage reached, explicit ratings). No LLM calls, no new embeddings.
+3. Each row has **Add** (with a Miniflux category picker; calls `POST /v1/feeds`) and **Dismiss**.
+
+Over time the subscribed set grows and the pool of direct-feed articles each issue draws from grows with it.
+
+Out of scope (deliberately, see §7): auto-subscribing, feed previews/health checks, Scour integration, OPML, per-feed LLM judgement, un-dismissing from the UI.
+
+## 2. Verified facts
+
+### About this repo
+
+- **Pipeline order** (`src/pipeline.rs:354` `run_stages`): ingest → dedupe → extraction → `persist_articles` (stage 4, ~line 443, mints real article ids) → social enrichment (stage 5, best effort, ~line 448) → hygiene/embeddings/signals (stage 6) → … Failure policy is documented at the top of the file: *best effort* stages log, push a warning onto `report` (status `degraded`) and continue. The new stage is best effort.
+- **How an article arrived** is stored per article in `articles.sources_json` as `Vec<SourceRef>` (`src/types.rs:64`), each with a `SourceKind` (`Scour | HnFrontpage | Lobsters | Reddit | Feed`, `src/types.rs:49`). Classification is `dedupe::classify_source_with_feed` (`src/dedupe.rs:177`). `Article::came_via(kind)` exists (`src/types.rs:147`). "Aggregator-only" therefore means `!article.sources.iter().any(|s| s.kind == SourceKind::Feed)`.
+- **Ingest already loads the whole subscription list once per run**: `MinifluxClient::ingest_window` returns `(Vec<Entry>, HashMap<FeedId, FeedMeta>)` where `FeedMeta` has `feed_url` and `site_url` (`src/miniflux.rs:105`). That map is the "already subscribed" set; no extra call needed in the pipeline.
+- **Miniflux client** (`src/miniflux.rs`) is currently GET-only: one private `get_json` helper with retry (`RetryPolicy`, retry on network/5xx/429), `X-Auth-Token` auth, `MinifluxError::{Http, Status, Decode, MissingApiKey}`. Module doc says "Reads only … read state is never mutated" — still true for the pipeline; the dashboard **Add** action is the only writer and only creates feeds.
+- **Per-article ranking evidence is persisted** in `candidate_runs` (`migrations/0002_curation_v2.sql:59`): `(run_id, article_id) PK, stage, excluded_reason, signals_json, utility REAL, rank_utility, …`. `signals_json` decodes to `curate::telemetry::SignalsJson` (`src/curate/telemetry.rs:114`) whose `blend()` returns the preliminary blend on 0–100 and whose `top_interests: Vec<TopInterest{name, z, cos}>` names the matched interests. `utility` (0–100) is set only for articles that reached the deep set (`admitted`/`assessed`/`shortlisted`/`selected`). Stage names: `dashboard::STAGES` (`src/web/dashboard/mod.rs`). `runs.status` distinguishes finished runs; dry runs are not flagged in `runs` (a dry run still writes telemetry, which is fine to use).
+- **Ratings**: `Db::current_ratings(lookback_days) -> Vec<RatedArticle>` (`src/db.rs:708`) returns one current verdict per article with `value` (`loved` 1.0, `good` 0.35, `not_for_me` −1.0) — the same numbers `signals::RatedExample` uses.
+- **Dashboard conventions**: one submodule per page group under `src/web/dashboard/`, each exposing `routes() -> Router<AppState>` merged in `dashboard::router()` (`src/web/dashboard/mod.rs:41`). Admin gating is applied by the caller. POST-then-redirect with a session flash is the established pattern (`users::approve`, `src/web/dashboard/users.rs:122`, uses `set_flash(&session, "error"|"ok", text)` then `Redirect::to`). Nav tabs are hardcoded in `src/web/templates/layout.html:47–54` keyed on `page.active_nav`. Overview tiles live in `src/web/templates/dashboard/overview.html`. Templates are askama; shared pager is `dashboard/_pager.html`.
+- **`AppState`** (`src/server.rs:79`) holds `db`, `config: Arc<RwLock<Arc<Config>>>` (read via `state.config()`), `web: Arc<WebState>`, `mailer`. Handlers construct outbound clients from config as needed (`bookorbit.rs` does this for OPDS); reuse whatever shared `reqwest::Client` `WebState` already carries, otherwise `http::build_client(http::DEFAULT_TIMEOUT)`.
+- **Config**: sections are `#[serde(deny_unknown_fields, default)]` structs on `Config` with `Default` impls; env override is `DAILY_EPUB_<SECTION>__<KEY>`. The settings dashboard has a **hardcoded section list**, help text and a test asserting the list (`src/web/dashboard/settings.rs`, see the BookOrbit plan §2 for the exact spots) — a new section must be added there or the settings page/test breaks. `config.example.toml` and the README config table document every key.
+- **Migrations**: `sqlx::migrate!("./migrations")`; latest is `0009_request_username.sql`, so the new file is `0010_feed_discovery.sql`.
+- **Jobs / CLI**: catalogue jobs are in `src/jobs.rs` and run through `main.rs` (`Job::ImportRatings => imports::run(...)`). A one-off backfill only needs a CLI subcommand, not a job (§4 step 6).
+
+### About Miniflux (docs, 2026-09-07)
+
+- **Discover**: `POST /v1/discover` with body `{"url": "<page or site url>"}` → `[{"url": "<feed url>", "title": "…", "type": "rss|atom|json"}]`. Optional body fields (`username`, `password`, `user_agent`, `fetch_via_proxy`) are not needed. **Observed live on 2026-09-07** (operator ran it against several hosts):
+  - When the page has no `<link rel="alternate">`, Miniflux falls back to probing well-known paths on the site root (`/atom.xml`, `/feed.atom`, `/feed.xml`, `/feed/`, `/index.rss`, `/index.xml`, `/rss.xml`, `/rss/`, `/rss/feed.xml`) and **returns every path that answered 200 without checking that the body is a feed**. A site that serves its SPA shell for any path (zombo.com, immich, BookOrbit) yields up to nine bogus results, each with `title == url`. **Discover results are leads, not facts; every one must be validated before it is stored (§3, §4 step 3).**
+  - When the target site fails, the response is a 4xx/5xx with `{"error_message": "fetcher: bad gateway (502 status code)"}`, `"fetcher: unexpected status code (412 status code)"`, or `"resource not found"` (nothing found / 404). Treat all of these as "host checked, zero candidates" and move on; never retry within the run.
+  - Real `<link rel="alternate">` hits work from an **article** URL. Observed for `https://blog.philz.dev/blog/language-server-db/`:
+    `[{"title":"blog.philz.dev","url":"https://blog.philz.dev/feed/feed.xml","type":"atom"},{"title":"blog.philz.dev","url":"https://blog.philz.dev/feed/feed.json","type":"json"}]`.
+    The same content is offered twice (Atom and JSON Feed) under one title, so link-tag hits need deduping by title too (§3). Miniflux substitutes the URL for the title when the tag has none, so `title == url` marks a result as a well-known-path guess in practice.
+- **Create feed duplicate**: observed `HTTP 400` with `{"error_message":"This feed already exists."}`. The flash shows `error_message` verbatim; on that exact message the row is also flipped to `added` (without a `miniflux_feed_id`), since the operator subscribed by other means.
+- **Create feed**: `POST /v1/feeds` with `{"feed_url": "…", "category_id": <int>}` → `{"feed_id": <int>}`. Errors come back as 4xx/5xx with a JSON `error_message`; a duplicate subscription is a 4xx (*assumption:* 400 with "This feed already exists"). Surface `error_message` in the flash rather than special-casing.
+- **Categories**: `GET /v1/categories` → `[{"id", "user_id", "title", "hide_globally"}]`.
+- **Feeds**: `GET /v1/feeds` elements carry `feed_url` and `site_url` (already modelled as `MinifluxFeed`).
+- API keys are full-access; the existing key can create feeds. Nothing to provision.
+
+## 3. Design decisions (settled)
+
+| Topic | Decision | Why |
+|---|---|---|
+| Where discovery runs | A best-effort **pipeline stage right after social enrichment** (needs real article ids, before hygiene). Plus a CLI backfill (`daily-epub feeds discover --days N`) that runs the same function over recent `articles`, for seeding. | The user asked for "a step in article processing". The backfill is the same function behind a flag; without it the page is empty until tomorrow. |
+| Which articles | Aggregator-only articles: no `SourceKind::Feed` in `sources`. Skip when the canonical URL's host is in `discovery.skip_hosts` or matches the host of any subscribed feed's `site_url`/`feed_url`. | Articles that already came through a direct feed prove nothing. Host match against subscriptions catches "same site, different feed URL" cheaply. |
+| Discovery mechanism | **Miniflux `POST /v1/discover`** with the article URL, followed by **our own validation fetch** of each returned URL. No new crate. | Miniflux already does `<link rel=alternate>` + well-known paths + YouTube etc. and runs on the same host, but its well-known-path guesses are unverified (§2). Validating is ~40 lines; replacing discover with a home-built finder is far more. |
+| Validation | `GET` each discovered URL with the shared client (10 s timeout, read at most 256 KB). Accept only if the body, after an optional BOM, whitespace and `<?xml …?>` declaration, starts with `<rss`, `<feed`, or `<rdf:RDF`, or is JSON containing `"https://jsonfeed.org/version/`. Take the feed's own `<title>` from that body (first `<title>…</title>` in the buffer, unescaped, trimmed) as the candidate title when Miniflux gave `title == url`. Any other body, a non-2xx status or an error rejects the URL. | Content-type alone is unreliable (SPAs return `text/html` for everything, some real feeds return `text/xml` or `application/octet-stream`). Sniffing the root element is cheap and decisive. |
+| Duplicate results | After validation: group link-tag hits (`title != url`) by `title`, keeping one per group and preferring `type` `rss`/`atom` over `json`; then at most **one** `title == url` guess (the first in Miniflux's order); at most 3 per host overall. | blog.philz.dev offers the same feed as Atom and JSON Feed under one title; WordPress answers `/feed/` and `/rss/`, Hugo `/index.xml` and `/feed.xml`, all with the same content. One is enough. Real tag/category feeds arrive with distinct link-tag titles and are kept. |
+| Per-host memo | Table `feed_discovery_hosts(host PK, checked_at, candidates)`. A host is looked up **once**; re-checked only after `RECHECK_DAYS = 90` (const). New articles on an already-checked host are just **linked** to that host's existing candidates (no network). | Keeps per-run lookups bounded and lets a candidate accumulate evidence for free. |
+| Per-run cap | `discovery.max_lookups_per_run` (default 30), concurrency 4, 10 s timeout per lookup. Order: articles with the highest social score first. | A run already takes ~12 min; discovery must not add more than ~1 min. |
+| Multiple feeds per host | Drop results whose URL or title contains `comment` before validating. Each kept result is one candidate keyed by canonicalized `feed_url` (unique). | Comment feeds are noise; tag/category feeds are a real choice the operator can make on the page. |
+| Ranking | Pure function over the candidate's linked articles (§4 step 4): per-article evidence `s_i ∈ [−1, 1]` = explicit rating value if rated; else `0.85` if `stage = selected`; else `utility/100` if present; else `blend()/100` if present; else no evidence. Feed score = shrunk mean `(Σ s_i + prior·k) / (n + k)` with `prior = 0.3`, `k = 2`, shown as 0–100. Sort: score desc, then `n` desc, then `last_seen` desc. | Reuses exactly the signals the paper selects on (interest, knn, feed, social, heuristic, triage, quality, fit) with zero new cost. Shrinkage stops a single 95-utility article outranking three 80s. Constants live in one place; not configurable (YAGNI). |
+| "Why" column | The three most frequent `top_interests[].name` across the linked articles, plus the linked article titles (top 3 by `s_i`) linking to `/dashboard/articles/{id}`. | Enough to decide at a glance; all read from `signals_json`, no extra work. |
+| Add | Row form: `<select name="category_id">` + **Add** → `POST /dashboard/feeds/{id}/add` → Miniflux `POST /v1/feeds` → set `status = 'added'`, `miniflux_feed_id`, `decided_at`; flash "Added *title* to *category*". The select defaults to the last category used (`kv` key `feed_discovery_last_category`). | The operator will click Add many times in a row; remembering the category saves a click each time. |
+| Categories | `GET /v1/categories` **on page render**, one call. If it fails: flash the error and render the table with Add disabled. | Categories change rarely but caching them is more code than a call. |
+| Dismiss | `POST /dashboard/feeds/{id}/dismiss` → `status = 'dismissed'`, `decided_at`. No restore button. | Dismissals are cheap to undo with SQL if ever needed. |
+| Reconciliation | At each run's discovery stage, any `candidate` whose `feed_url` (or host) now appears in the subscribed feed map becomes `added` (with `miniflux_feed_id`). | Feeds added directly in Miniflux disappear from the list without manual bookkeeping. |
+| Page filter | `?status=candidate|added|dismissed` (default `candidate`), allow-listed; paginated with `_pager.html`, 50 rows. | One query param buys an audit view of what was added/dismissed. |
+| Config | `[discovery] enabled = true, max_lookups_per_run = 30, skip_hosts = [...]`. | Exactly the knobs that need turning: kill switch, run-time bound, noise list. |
+
+## 4. Implementation steps
+
+1. **Migration** `migrations/0010_feed_discovery.sql`:
+   ```sql
+   CREATE TABLE feed_candidates (
+       id               INTEGER PRIMARY KEY AUTOINCREMENT,
+       feed_url         TEXT NOT NULL UNIQUE,
+       host             TEXT NOT NULL,
+       title            TEXT,
+       status           TEXT NOT NULL CHECK (status IN ('candidate', 'added', 'dismissed')),
+       first_seen       TEXT NOT NULL,
+       last_seen        TEXT NOT NULL,
+       miniflux_feed_id INTEGER,
+       decided_at       TEXT
+   );
+   CREATE INDEX idx_feed_candidates_status_host ON feed_candidates(status, host);
+
+   CREATE TABLE feed_candidate_articles (
+       candidate_id INTEGER NOT NULL REFERENCES feed_candidates(id) ON DELETE CASCADE,
+       article_id   INTEGER NOT NULL REFERENCES articles(id) ON DELETE CASCADE,
+       PRIMARY KEY (candidate_id, article_id)
+   );
+
+   CREATE TABLE feed_discovery_hosts (
+       host       TEXT PRIMARY KEY,
+       checked_at TEXT NOT NULL,
+       candidates INTEGER NOT NULL
+   );
+   ```
+   `Db` methods (in a new `src/discovery.rs`, not `db.rs`, following `imports.rs`): `hosts_checked(hosts) -> HashMap<host, (checked_at, candidates)>`, `mark_host_checked`, `upsert_candidate(feed_url, host, title, now) -> id` (bumps `last_seen`, never demotes `added`/`dismissed`), `link_article(candidate_id, article_id)`, `candidates_for_host(host)`, `list(status, page)`, `set_status(id, status, miniflux_feed_id, now)`, `reconcile_added(subscribed: &[(feed_url, site_host)], now)`, `count(status)`.
+
+2. **Miniflux client** (`src/miniflux.rs`): add a private `post_json<B: Serialize, T: DeserializeOwned>(path, body)` mirroring `get_json` (same retry predicate; **do not retry** `create_feed` on 5xx — a retried create can double-subscribe; pass `RetryPolicy::none()` or a flag). Wire types `Discovered { url, title, type }`, `Category { id, title }`, `CreatedFeed { feed_id }`. Methods: `discover(url) -> Vec<Discovered>`, `categories() -> Vec<Category>`, `create_feed(feed_url, category_id) -> i64`. Make `MinifluxError::Status` keep the `error_message` string when the body is JSON so the flash reads "This feed already exists" rather than raw JSON. Update the module doc's "reads only" sentence. Tests: deserialize fixtures for all three.
+
+3. **Discovery stage** (`src/discovery.rs` + wiring in `src/pipeline.rs` after stage 5, timing key `"discovery"`, report count `feed_candidates_new`, warning on error):
+   ```text
+   select aggregator-only articles → drop skip_hosts / subscribed hosts
+     → reconcile_added(subscribed)
+     → for each distinct host: if checked within RECHECK_DAYS → link article to its candidates
+                              else queue (cap max_lookups_per_run, highest social score first)
+     → discover() ×4 concurrent (an error_message response = host checked, 0 candidates)
+     → drop "comment" results and already-subscribed feed_urls
+     → validate each remaining URL (GET, ≤256 KB, feed-root sniff, pull <title>)
+     → one link-tag hit per title (xml over json) + at most one guessed URL, max 3
+     → upsert_candidate + link_article + mark_host_checked
+   ```
+   The function signature is `pub async fn run(db, miniflux: &MinifluxClient, http: &reqwest::Client, cfg: &DiscoveryConfig, articles: &[Article], subscribed: &HashMap<FeedId, FeedMeta>, now) -> Result<Summary>` so the pipeline and the CLI share it. Host = `url::Url::host_str()` lowercased with a leading `www.` stripped; compare subscriptions the same way. Budget: one discover call plus up to nine validation GETs per host, so with the 30-host cap the stage is bounded at ~300 small requests, 4 in flight; log the count. Pure helpers (`aggregator_only`, `host_of`, `keep_result`, `sniff_feed(&[u8]) -> Option<FeedKind>`, `feed_title(&[u8])`, `dedupe_guesses`) get unit tests, including the observed zombo.com response (nine `title == url` guesses that all fail the sniff → zero candidates), the observed blog.philz.dev response (Atom + JSON under one title → exactly the Atom candidate), and an SPA shell body (`<!doctype html>…`) rejected by `sniff_feed`.
+
+4. **Ranking** (`src/discovery.rs`, pure): `pub fn score(evidence: &[ArticleEvidence]) -> f64` and `pub fn why(evidence) -> Vec<String>` per §3. Evidence loading is one query per page render: for the page's candidates, `SELECT article_id, stage, utility, signals_json FROM candidate_runs WHERE article_id IN (…) ORDER BY run_id DESC` keeping the latest row per article, joined with `current_ratings`. The page holds ≤ 50 candidates × a handful of articles each, so ranking happens in Rust after loading **all** `candidate`-status rows (sorting must be global, not per page). If the candidate count ever exceeds ~2 000 this needs a stored score; not now.
+   Unit tests: rated article dominates; shrinkage (one 0.95 article scores below three 0.8s); no evidence → prior; `why` picks the modal interests.
+
+5. **Dashboard page** `src/web/dashboard/feeds.rs` + `src/web/templates/dashboard/feeds.html`:
+   - Routes: `GET /dashboard/feeds`, `POST /dashboard/feeds/{id}/add`, `POST /dashboard/feeds/{id}/dismiss`. Merge into `dashboard::router()`. Nav tab **Feeds** in `layout.html` (`active_nav = "feeds"`). Overview tile "Feed candidates → review" linking to the page.
+   - Table columns: Score (0–100, tabular numerals), Feed (title → `feed_url`, host beneath), Why (interest names + up to 3 article titles linking to the article page), Articles (n), Seen (first/last via `format_time`), Actions (category select + Add; Dismiss). `?status=` filter links at the top. Added rows show the category and a link to the Miniflux feed page (`{base_url}/feeds/{miniflux_feed_id}`); dismissed rows show only the date.
+   - Add handler: read `category_id` from the form and pass it through (Miniflux validates it), call `create_feed`. On `Ok` set status + `kv` last category + flash ok. On a 400 whose `error_message` is `This feed already exists.` set status `added` and flash that message as info. On any other `Err` flash `error_message` (or the transport error) and leave the row as `candidate`. Requires `state.config().miniflux.api_key`; if the client fails to build, flash "Miniflux API key is not configured".
+   - Server test in the existing dashboard test harness: page renders with an empty table; add/dismiss flip `status` (point `miniflux.base_url` at a `tokio` listener that answers the create call, as the BookOrbit tests do for OPDS; note the loopback-bind caveat in `memory/codex-sandbox-quirk.md`).
+
+6. **CLI backfill** (`src/main.rs`): `daily-epub feeds discover [--days 14] [--limit 200]` — loads `articles` with `first_seen` in the window, fetches the feed map (`MinifluxClient::feed_map`), calls `discovery::run` with `max_lookups_per_run = limit`, prints the summary. Takes the pipeline run lock (it writes the same tables the run does). No job-catalogue entry.
+
+7. **Config + docs**: `DiscoveryConfig { enabled: bool, max_lookups_per_run: usize, skip_hosts: Vec<String> }` with defaults `true, 30, ["news.ycombinator.com", "lobste.rs", "reddit.com", "github.com", "gist.github.com", "x.com", "twitter.com", "youtube.com", "en.wikipedia.org", "arxiv.org", "docs.google.com"]`. Register the section in the settings dashboard (list, help text, test). Document in `config.example.toml` and the README table. Add a short "Feeds" paragraph to the dashboard section of the README.
+
+Order matters only for 1 → 2 → 3 → 4 → 5; 6 and 7 can be done alongside. Expect roughly 900 lines including tests.
+
+## 5. Verification
+
+- `cargo test` green; new pure-function tests in `discovery.rs`, wire-type tests in `miniflux.rs`, one handler test for the page.
+- Live, on the server after deploy: run `daily-epub feeds discover --days 14 --limit 50`, open `/dashboard/feeds`, confirm the top rows look like feeds the operator would actually want, click **Add** on one, confirm it appears in Miniflux under the chosen category and the row flips to *added*. Run `generate --dry-run` and check the report has a `discovery` timing under ~60 s and no warning.
+- Check the `journalctl` line for how many hosts were skipped as already subscribed; if it is near zero the `www.`/host normalisation is wrong.
+- Check the line for discover results rejected by validation. A healthy day should reject a good share of them (SPA catch-alls); zero rejections means the sniff is too lenient, and near-total rejection means it is too strict (look for feeds served with a leading comment or DOCTYPE).
+
+## 6. Rollout notes
+
+- Migrations run automatically on the first `daily-epub` command after deploy.
+- No new secrets: the existing `DAILY_EPUB_MINIFLUX__API_KEY` can create feeds.
+- Seed the page once with the CLI backfill so it is useful on day one.
+- Every Miniflux behaviour the design depends on was observed live on 2026-09-07 (§2); the recorded responses are the test fixtures. Nothing remains to confirm before implementation.
+
+## 7. Non-goals (do not add)
+
+- Auto-subscribing without a click, or any LLM judgement of feeds.
+- Fetching or previewing feed contents, feed health checks, unread counts.
+- Un-dismiss / undo buttons, per-row notes, bulk actions, sorting controls (the list is already sorted by the only order that matters).
+- A stored/cached score column, a scheduled job, OPML export, Scour "recommended feeds" integration (ideas.md item, separate).
+- Configurable ranking constants.

+# First-class interests: a table, a page, categories, links, and a rating-driven weight
+
+**Date:** 2026-09-12
+**Repository:** `thallada/the-daily-epub`
+**Status:** implementation plan, ready to execute
+**Builds on:** `docs/plans/2026-09-02-personalized-curation-v2.md` (§8 profile and interests, §9 cheap signals, §12 blend and utility), `docs/plans/2026-09-03-web-dashboard.md` (page conventions), `docs/plans/2026-09-07-feed-discovery.md` (the most recent page + job + CLI addition; copy its shapes)
+
+Written for a fresh implementation agent. Facts about this repo were checked against `main` (`e82f7b0`) on 2026-09-12. Nothing here depends on an external service beyond the LLM providers and Voyage that the pipeline already uses.
+
+---
+
+## 1. Goal
+
+Today the reader's ~230 standing interests live in a Scour OPML export (`data/scour-interests.opml`) plus an optional `## Interests` section of `profile.md`. They are parsed on every run, embedded, matched against each day's articles (`signals::interest_matches`), grouped for the system prompt by a hand-written keyword table (`profile/themes.rs`), and — since the last commit — shown to the reader as the **Matches:** line under every article header. They cannot be added from the dashboard, ratings never touch them, and nothing links from an interest to the articles that matched it.
+
+This plan makes interests a first-class record:
+
+1. **A database table is the only source of interests.** The OPML and the profile's `## Interests` section become one-time import inputs.
+2. **An Interests dashboard page** lists them with category, weight, and match counts; adds new ones; filters by category; changes a category by hand; deletes.
+3. **Categories** are kept (the grouped view the operator likes) and assigned by an LLM in one daily batch, only when uncategorized interests exist, with a manual **Categorize now** button.
+4. **Every interest name in the web UI is a link** to the Articles page filtered (and sorted) to the articles that matched it, with a cut-off so unrelated articles never appear. The Articles page gains an interest filter and an interests column.
+5. **Ratings nudge interests.** Each explicit rating credits the interests the article matched, scaled by how strongly it matched; the resulting per-interest weight is shown on the Interests page (default sort: highest first) and feeds curation as one bounded signal, so diversity is preserved.
+6. **Backfill** is two CLI commands the operator runs once.
+
+## 2. Verified facts
+
+### Interests today
+
+- `profile::parse_interests(opml)` reads `<outline text="…">` names; `parse_profile_str` strips `## Interests` from `profile.md` and returns its lines; `union_interests` dedupes case-insensitively (`src/curate/profile/mod.rs:36–150`). `load_standing_interests(opml, profile)` is called from `pipeline::prepare_features` (`src/pipeline.rs:946`), `embedding::plan_backfill` (`src/curate/embedding.rs:901`), and `profile::load_or_build`/`rebuild` (through `prompt_inputs`). `config.interests_opml` is referenced in 20 places in `src/` (mostly tests that write a temp OPML), `config.example.toml:29`, README (lines 103 and 369), and `docs/runbooks/curation-v2-migration.md`.
+- The system prompt's "Standing interests" section groups names with `profile::group_into_themes` (`src/curate/profile/themes.rs`): twelve keyword themes plus "Other standing interests", deterministic, sorted. The profile dashboard page renders the same grouping (`src/web/dashboard/profile.rs:249`, template `dashboard/profile.html:42`).
+- `interest_embeddings` (migration 0002) is keyed by the interest **name**; `EmbeddingService::interests(&[String])` returns cached vectors and fetches misses (`src/curate/embedding.rs:743`). A new name is embedded automatically the next time it is passed.
+- `signals::interest_matches(article_embeddings, interest_embeddings)` (`src/curate/signals.rs:492`) computes cosine per interest × article, z-scores each interest across the day's embedded articles (std floored at 1e-3; raw top-1 cosine fallback under 30 articles), keeps the top `RECORDED_TOP = 3` per article as `TopInterest { name, z, cos }`, and scores `0.7·z₁ + 0.3·mean(top-3 z)`. `signals.top_interests` is serialized into `candidate_runs.signals_json` (`telemetry::serialize_signals`), copied into `Pick.top_interests` as bare names by the editor (`src/curate/editor.rs:598`), and rendered as the Matches line by `chapters::understanding` → `_understanding.html` (web) and `chapter.xhtml` / `in_this_issue.xhtml` (EPUB). Prompts list interests with `z ≥ 1.5` as "matches" (`triage.rs:135`, `assess.rs:192`, `editor.rs:159`).
+- Interest names also appear on: the dashboard article detail (`dashboard/article.html:61`, "Top interests" table), `_signals_table.html:5` (runs and article history), and the Feeds page "Why" badges (`dashboard/feeds.html:14`, from `discovery::why`).
+- Daily volume: ~365 entries → a few hundred articles per run; 512-dim `voyage-4-lite` vectors; `embedding_retention_days = 120`, so the embedding cache holds on the order of 30–50 k vectors (≈2 KB each). Scanning the cache per web request is not an option; a per-run cosine pass is milliseconds (§9.1 of the curation plan).
+
+### Ratings and the learned signals
+
+- `rating_events` is append-only; `Db::current_ratings(lookback_days) -> Vec<RatedArticle>` returns the latest explicit verdict per article with `value` (`loved` 1.0, `good` 0.35, `not_for_me` −1.0, `slop` per `feedback.slop_value`) and `event_at` (`src/db.rs:713`). Ratings are written by `web::rate::post` (dashboard and issue pages), `rate::record_explicit` (CLI), and `imports::run`.
+- `signals::PreferenceState::load` (`src/curate/signals.rs:238`) builds the run's learned state from current ratings: decayed weights `value × 0.5^(age/half_life)`, kNN over rated embeddings, and **feed/author affinity** as Beta-smoothed rates `(up+1)/(up+down+2)` with a gate `gate(n, feed_floor=15, feed_full=40)`. Every cheap signal is `Option<f64>`, percentile-normalized over the eligible set (`normalize`, `PERCENTILE_SIGNALS`), blended with renormalized weights (`preliminary_blend`; `rank::calculate_utility_for` for the deep set). Absent is never zero. The slop-author factor scales both blends. Diversity is enforced downstream by `rank::shortlist` (cluster threshold 0.85, `per_cluster_cap = 2`, `utility_protected = 10`) and by the editor prompt.
+- Signal names are enumerated in: `signals::PERCENTILE_SIGNALS`, `Signals::raw`, `preliminary_blend`'s candidate list, `rank::calculate_utility_for`'s weighted list, `telemetry::serialize_signals` (raw list) and `RENDERED_SIGNALS`, `dashboard::SIGNAL_NAMES`, `config::{PreliminaryWeights, UtilityWeights}`, and `settings::SETTINGS_HELP`. A new signal touches all of them.
+- The Ratings dashboard page computes each verdict's feed credit on the fly with a pure function (`ratings::contribution`) rather than storing it. Follow that precedent.
+
+### Dashboard, jobs, CLI, config
+
+- One submodule per page group under `src/web/dashboard/`, each with `routes()`, merged in `dashboard::router()`; admin gating is applied by the caller. Nav tabs are hard-coded in `src/web/templates/layout.html` (keyed on `page.active_nav`); overview tiles in `dashboard/overview.html`. POST → flash → redirect via `jobs::set_flash`. `Page::is_admin()` is available in every template. Pager partial `dashboard/_pager.html`; client-side row filter `data-table-filter`.
+- The Articles list (`src/web/dashboard/articles.rs`) builds `ARTICLE_INNER` (articles ⨝ best entry ⨝ latest `candidate_runs` row ⨝ assessments, with correlated subqueries for rating and publication) and wraps it in `SELECT * FROM (…) x WHERE 1=1 {clauses} ORDER BY {sort}`. Filters are allow-listed; sorts come from `ARTICLE_SORTS`; `Pager::new(pagination, path, &filters.params())` round-trips them.
+- Jobs are a fixed catalogue (`jobs::Job`, `CATALOGUE`, `parse`, `name`, `description`, `takes_lock`, `dangerous`) run as `daily-epub-job@<name>.service` and dispatched in `main::run_job`. The profile page starts `profile-rebuild` with a plain form posting to `/dashboard/jobs/profile-rebuild`. The only daily entry point is the `daily-epub-generate.timer` (05:30 America/New_York).
+- `pipeline::build_llms` (`src/pipeline.rs:1133`) builds the taste-profile prompt, the clients, and runs the weekly learned-adjustments rebuild, then rebuilds the clients with the new prompt. An LLM step that must precede the prompt goes here.
+- Config sections are `#[serde(deny_unknown_fields, default)]`; an unknown top-level key makes `Config` fail to load. The settings page has a hard-coded `GROUP_ORDER`, `PATH_KEYS`, and `SETTINGS_HELP`, with a test over the section list. Migrations: `sqlx::migrate!("./migrations")`; latest is `0012_article_publication.sql`, so the new file is `0013_interests.sql`. `db.rs` has a migration test asserting a table list (`src/db.rs:1720`).
+
+## 3. Options considered
+
+### 3.1 Where "articles matching interest X" comes from
+
+| Option | How | Verdict |
+|---|---|---|
+| A. Compute on request | Load the interest vector and every cached article embedding, dot, sort. | **Rejected.** 30–50 k × 2 KB per request; the dashboard is 1–7 ms today and should stay there. |
+| B. Query `candidate_runs.signals_json` with `json_each` | The top-3 names are already persisted per run. | **Rejected.** A JSON scan over every telemetry row (hundreds of thousands, pruned at 180 days) per request, no index, and rows vanish with telemetry retention. |
+| C. **A junction table written by the signals stage** | `article_interests(article_id, interest_id, cos, z)`: the same top-3 the run already computes, one row each, indexed by interest. The filter is an indexed join. | **Chosen.** ~1 k rows/day, zero extra computation, and the backfill is one pass over cached embeddings. |
+
+### 3.2 How an interest weight is computed and stored
+
+| Option | How | Verdict |
+|---|---|---|
+| A. Stored counters updated on every rating event | Add `up/down` columns to `interests`; the rating handlers, CLI, and importer bump them; write a backfill migration script. | **Rejected.** Four write paths to keep in sync, decay cannot be stored (it is a function of *now*), and it duplicates the ratings history that already exists. |
+| B. **Derived on the fly from current ratings × matches** | One pure function over `current_ratings` and their `article_interests` rows, exactly like feed affinity. The run computes it in `PreferenceState::load`; the Interests page computes it on render. | **Chosen.** No new write path, always current, decay and lookback for free, backfill is "make sure rated articles have match rows". ≤ a few hundred ratings × 3 rows: microseconds. |
+| C. Ask the weekly learned-adjustments rebuild to write per-interest weights | An LLM judges the rating history per interest. | **Rejected.** Non-deterministic, weekly, and the numbers would not be explainable. The existing prose rebuild already sees the ratings. |
+
+### 3.3 How the weight enters curation
+
+| Option | How | Verdict |
+|---|---|---|
+| A. **A new bounded cheap signal, `affinity`** | Per article: match-strength-weighted mean of its matched interests' weights; percentile-normalized; gated on rating count; small configured weight in the preliminary blend and the utility. | **Chosen.** Fits the existing design (absent ≠ zero, renormalized weights, `explain` shows it), and its influence is capped at its weight share, so one runaway interest cannot dominate. Diversity machinery downstream is untouched. |
+| B. Multiply each interest's z by its weight before the top-3 is taken | Changes which interests appear as matches. | **Rejected.** Entangles "what does this article match" with "what does he like", and the Matches line would drift with ratings. |
+| C. Annotate the prompt's Standing interests with ↑/↓ | Cheap and the LLM would use it. | **Deferred** (§9). Worth adding once the weights have a few weeks of ratings behind them; it is a five-line change on top of this plan. |
+| D. A new deep-set admission retriever by affinity | Like the `interest` and `knn` quotas. | **Rejected.** More slots for the same signal; the blend fill already admits high-affinity articles. |
+
+### 3.4 Categories
+
+| Option | Verdict |
+|---|---|
+| A. **`interests.category TEXT NULL`; the category set is the distinct values** | **Chosen.** No FK, no second page, renaming is an `UPDATE`. |
+| B. A separate `interest_categories` table with FK | Rejected: a table with one meaningful column. |
+| C. Keep the keyword table in `themes.rs` | Rejected as the source of truth (the user wants DB-tracked interests and LLM categorization), but **kept for the one-time import** so the current grouping survives unchanged. |
+
+### 3.5 When the categorizer runs
+
+| Option | Verdict |
+|---|---|
+| A. **Inside `generate`, before the prompt is built, only when uncategorized interests exist; plus a catalogue job for the button** | **Chosen.** The morning timer is the only daily trigger that exists; a run without new interests spends nothing. |
+| B. Its own systemd timer | Rejected: another unit to install for a call that takes seconds. |
+| C. Synchronously in the Add handler | Rejected: an LLM call in a request path, and the user asked for a daily batch. |
+
+## 4. Design decisions (settled)
+
+| Topic | Decision |
+|---|---|
+| Match rule (one definition everywhere) | An interest **matches** an article when it is among the article's top three interests by z **and** `z ≥ MATCH_MIN_Z = 1.0`. `interest_matches` applies this when it truncates, so `signals.top_interests`, the Matches line, the stored rows, the Articles filter, and the interest weights all agree. The score formula is unchanged (computed before the cut). The prompts keep their stricter `z ≥ 1.5` for "matches interests". |
+| Stored rows | `article_interests(article_id, interest_id, cos, z, run_id)`, upserted per eligible article per run (the same article can be eligible on consecutive days; the latest run wins; cosine is stable, z is that day's). Rows are never pruned (≈40 bytes each, ~1 k/day). |
+| Link target and filter key | `/dashboard/articles?interest=<name>`: names are unique (case-insensitive), human-readable, and `Pick.top_interests` already carries names, so no id has to travel through `issue_json`. The handler resolves the name to an id; an unknown name yields an empty list, never an error. When `interest` is set and `sort` is absent, the sort defaults to `match` (cosine descending). |
+| Who sees links | The dashboard is admin-only, so the Matches line links only for admin viewers (`page.is_admin()`); readers and anonymous visitors see plain text as today. The EPUB never links. |
+| Interest weight | Beta-smoothed rate over decayed, strength-scaled credits (§5.2): `(up + 1) / (up + down + 2)`, in (0, 1), 0.5 = no information. Shown with two decimals plus `up`, `down`, and the number of rated matches. |
+| Match strength | `s = clamp(z / 3, 0, 1)`: a z of 3 credits the full rating, a bare match (z = 1) a third. |
+| Curation signal | `affinity` (§5.3): signed, centred on zero, gated on the number of ratings that credited at least one interest (`affinity_floor = 15`, `affinity_full = 40`, same shape as the feed gate). Default weights: preliminary 0.10 (taken from `interest` 0.35→0.30 and `social` 0.10→0.05), utility 0.05 (taken from `knn` 0.15→0.10). |
+| Diversity | Guaranteed by construction: the signal's share of the blend is its configured weight (≤ 10 % / 5 %), percentile normalization caps a favourite interest's articles at percentile 1.0 of that one signal, Beta smoothing means a single *loved* moves a weight from 0.50 to at most 0.67, ratings decay with the 60-day half-life, and `rank::shortlist`'s per-cluster cap and the editor's diversity instructions are unchanged. No new cap is needed. |
+| Source of truth | The `interests` table. `interests_opml` is **removed** from config; `profile.md`'s `## Interests` section is still stripped by the parser but no longer read (the importer consumes it once; the profile page says so). |
+| Prompt grouping | "Standing interests" groups by `interests.category` (sorted by category name, members sorted case-insensitively); `NULL` renders under the existing label "Other standing interests". `themes.rs` is used only by the importer. |
+| Categorizer | One JSON call on the bulk provider over every uncategorized interest, given the existing category list; may create a category only when none fits. Unassigned names stay `NULL` and are retried the next day. Also the catalogue job `interests-categorize` behind the **Categorize now** button. |
+| Interests page actions | Add (name + optional category), change category (per-row select + Save), Delete (confirm; cascades match rows, deletes the cached embedding). No rename (delete + add). |
+| Backfill | `daily-epub interests import` (OPML + profile section → rows, categorized by the keyword table) and `daily-epub interests backfill` (match rows for every cached embedding). Weights need no backfill: they are derived. |
+| Config | No new section. `[curation.ranking]` gains `affinity_floor`, `affinity_full`; the two weight tables gain `affinity`. |
+
+## 5. The numbers
+
+### 5.1 Match rows
+
+In `prepare_features` (`src/pipeline.rs`), after `signals::compute_all` and before the candidates are handed on: for every candidate with non-empty `signals.top_interests`, upsert `(article_id, interest_id, cos, z, run_id)`. One transaction, `INSERT … ON CONFLICT(article_id, interest_id) DO UPDATE SET cos, z, run_id`. Names map to ids through the `interests` rows loaded at the top of the stage (the same rows whose names go to `service.interests`). Best effort: a failure is a report warning, never a failed run.
+
+### 5.2 Interest weight (pure, `interests::rates`)
+
+Inputs: `current_ratings(rating_lookback_days)` and the `article_interests` rows of those articles.
+
+```text
+for each current rating r on article a  (value v_r, decay d_r = 0.5^(age_days / half_life_days))
+  for each match row (a, i, z):
+     s      = clamp(z / 3, 0, 1)
+     credit = v_r × d_r × s
+     up_i   += max(credit, 0)
+     down_i += max(−credit, 0)
+     n_i    += 1
+weight_i = (up_i + 1) / (up_i + down_i + 2)          # 0.5 when n_i = 0
+```
+
+`cleared` verdicts are already excluded by `current_ratings`; `slop` carries `feedback.slop_value` like everywhere else. A rating is *attributable to interests* when it credits at least one interest; that count drives the gate.
+
+### 5.3 The `affinity` signal (pure, in `PreferenceState`)
+
+```text
+matched = the article's top_interests with n_i > 0
+affinity = Σ s_i × (weight_i − 0.5) / Σ s_i        absent when matched is empty or the gate is 0
+gate     = gate(attributable_interest_ratings, affinity_floor, affinity_full)
+```
+
+The raw value lives in [−0.5, 0.5]; it is percentile-normalized with the other cheap signals, weighted by `weights.preliminary.affinity × gate` in the blend and `weights.utility.affinity × gate` in the utility. `explain` and `_signals_table.html` show it like any other signal. The once-per-run preference log line gains `affinity gate … (n=…)`.
+
+## 6. Data model — `migrations/0013_interests.sql`
+
+```sql
+CREATE TABLE interests (
+    id             INTEGER PRIMARY KEY AUTOINCREMENT,
+    name           TEXT NOT NULL COLLATE NOCASE UNIQUE,
+    category       TEXT,                      -- NULL until categorized
+    created_at     TEXT NOT NULL,
+    categorized_at TEXT
+);
+CREATE INDEX idx_interests_category ON interests(category);
+
+CREATE TABLE article_interests (
+    article_id  INTEGER NOT NULL REFERENCES articles(id) ON DELETE CASCADE,
+    interest_id INTEGER NOT NULL REFERENCES interests(id) ON DELETE CASCADE,
+    cos         REAL NOT NULL,
+    z           REAL NOT NULL,
+    run_id      INTEGER,                      -- NULL for backfilled rows
+    PRIMARY KEY (article_id, interest_id)
+);
+CREATE INDEX idx_article_interests_interest ON article_interests(interest_id, cos DESC);
+```
+
+`interest_embeddings` stays keyed by name (no migration): a deleted interest also deletes its embedding row; a renamed one is a new interest.
+
+## 7. Implementation steps
+
+Sizes are rough line counts including tests. Steps 1–3 must be in order; 4–8 can proceed in parallel after 3; 9 last.
+
+1. **Migration + `src/interests.rs`** (~350). The table above; the db-list test in `db.rs` gains both tables. Module (following `discovery.rs`: data access, pure functions, and the LLM step in one file):
+   - `Interest { id, name, category, created_at, categorized_at }`; `list(db) -> Vec<Interest>` (ordered by name), `add(db, name, category, now) -> Result<id, Duplicate>` (trimmed, 1–80 chars, unique case-insensitive), `set_category(db, id, Option<category>, now)`, `delete(db, id)` (also `DELETE FROM interest_embeddings WHERE interest = name`), `names(db) -> Vec<String>`, `grouped(db) -> Vec<(String, Vec<String>)>` (for the prompt), `uncategorized(db)`.
+   - `replace_matches(db, run_id, &[(ArticleId, &[TopInterest])], names→ids)`; `matches_for_articles(db, ids) -> Vec<MatchRow { article_id, interest_id, name, cos, z }>`; `match_counts(db) -> HashMap<interest_id, i64>`.
+   - `pub fn rates(ratings: &[(ArticleId, value, decay)], rows: &[(ArticleId, interest_id, z)]) -> (HashMap<interest_id, Rate { up, down, n }>, attributable)` per §5.2, and `Rate::weight()`.
+   - Tests: uniqueness is case-insensitive; `rates` matches hand-checked numbers (a loved z=3 → up 1.0; a good z=1.5 → up 0.175; a not-for-me z=0.9 → nothing, below the cut); delete cascades; `grouped` puts `NULL` last under "Other standing interests".
+
+2. **Signals** (~250). In `signals.rs`: `MATCH_MIN_Z = 1.0` applied inside `interest_matches` after truncation; `Signals.affinity: Option<f64>`; `"affinity"` in `PERCENTILE_SIGNALS`, `Signals::raw`, `preliminary_blend` (gate `affinity_gate`); `PreferenceState` gains `interest_rates: HashMap<String, Rate>` (keyed by name — `TopInterest` carries names), `affinity_gate`, `attributable_interest_ratings`, `fn affinity(&self, top: &[TopInterest]) -> Option<f64>`, loaded in `load` from `interests::matches_for_articles(rated ids)` and exposed on `PreferenceSummary` and in `log`. `rank::calculate_utility_for` adds `("affinity", configured.affinity, candidate.signals.affinity_gate)`. `telemetry`: `serialize_signals` raw list and `RENDERED_SIGNALS`; `render_explain` prints it with the others. `dashboard::SIGNAL_NAMES` and `_signals_table.html` pick it up automatically once the name is in the list. Config: `RankingConfig { affinity_floor: 15, affinity_full: 40 }`, `PreliminaryWeights { affinity: 0.10, interest: 0.30, social: 0.05 }`, `UtilityWeights { affinity: 0.05, knn: 0.10 }`, `SETTINGS_HELP` lines, `config.example.toml`, README table.
+   Tests: the top-3 cut drops a z=0.4 third interest; affinity is absent under the gate and with no rated interests; a candidate matching a 0.8-weight interest outranks an otherwise identical one matching a 0.3-weight interest in the blend; blend weights still renormalize to 1.
+
+3. **Replace the OPML/profile plumbing** (~300, mostly deletions and test edits). `profile::load_standing_interests`, `parse_interests`, `union_interests`, and `prompt_inputs`' OPML argument go; `build`, `load_or_build`, `rebuild`, and `weekly_rebuild_if_due` take `grouped: Vec<(String, Vec<String>)>` from `interests::grouped(db)` instead of `interests: &[String]` + `group_into_themes`. `pipeline::prepare_features` and `embedding::plan_backfill` take names from `interests::names(db)`. `themes.rs` stays but is only referenced by the importer (step 8); `pub use themes::group_into_themes` is removed from the profile module. Remove `Config.interests_opml` (struct, `Default`, `config check` line, the `deny_unknown_fields` implication is a rollout note in §10), `settings::PATH_KEYS`/`SETTINGS_HELP`, `config.example.toml`, README (lines 103, 369), and the runbook mention. Every test that writes a temp OPML instead inserts rows with `interests::add`. The profile page loses the OPML card and the "Extracted `## Interests` lines" preview; in their place one line: "N standing interests in M categories — manage them on the Interests page", and the editor note says the `## Interests` section is ignored.
+
+4. **Match rows in the run** (~80). `prepare_features` writes them per §5.1 (timing folded into the existing `signals` timing; count `interest_matches` on the report counts is optional — skip unless free).
+
+5. **Articles page** (~200). `ArticlesQuery.interest: Option<String>` → `ArticleFilters.interest: Option<(i64, String)>` resolved by name (case-insensitive) in `from_query`'s caller (it needs the db; resolve in `list` before building filters, or make `from_query` async — pick the former). When set: `ARTICLE_INNER` gains `JOIN article_interests ai ON ai.article_id = a.id AND ai.interest_id = ?` (inside the inner query so `idx_article_interests_interest` drives it; the join is a `{interest_join}` placeholder that is empty otherwise) and exposes `ai.cos AS match_cos`; `ARTICLE_SORTS` gains `("match", "x.match_cos DESC, x.id DESC")`, which is the default when `interest` is set and `sort` is absent, and is ignored (falls back to `first_seen`) when it is not. Filter UI: a `<select name="interest">` over all interest names (blank = any), populated from `interests::list`. New column **interests**: for the page's ≤ 50 rows, one query through `matches_for_articles`, grouped per article, rendered as badges linking to `?interest=<name>` (ordered by z desc). `params()` round-trips `interest` and `sort=match`. Test: a seeded match row is found by the filter, an unknown name yields an empty table (200), and the column links.
+
+6. **Interests page** (~450). `src/web/dashboard/interests.rs` + `dashboard/interests.html`; routes `GET /dashboard/interests`, `POST /dashboard/interests` (add), `POST /dashboard/interests/{id}/category`, `POST /dashboard/interests/{id}/delete`. Nav tab **Interests** after Ratings; overview tile "N interests · M uncategorized". Page: add form (name, category select with a blank "let the categorizer decide" option), category filter tabs or select (`?category=<name>` and `?category=uncategorized`), sort select (`weight` default, `name`, `matches`, `added`), the `data-table-filter` row filter, no pager (≤ a few hundred rows). Columns: interest (link → `/dashboard/articles?interest=<name>`), category (link → `?category=`), weight (2 decimals, tabular; `—` when n = 0), up, down, rated matches n, matched articles (count), added (`format_time`), actions (category select + Save; Delete with `confirm`). Weights come from `interests::rates` over `current_ratings(rating_lookback_days)` computed on render; the header says which lookback and half-life it uses and shows the affinity gate state ("affinity gate 0.35 · 22 of 40 attributable ratings"), mirroring the Ratings page. **Categorize now** button posts to `/dashboard/jobs/interests-categorize` (the existing generic job route), shown enabled when `jobs_enabled` and disabled with the manual command otherwise, with the uncategorized count next to it. Flash messages for add/duplicate/deleted. Tests: page renders with weights sorted descending; add rejects a duplicate differing only in case; delete removes match rows and the embedding row; routes are admin-only.
+
+7. **Links everywhere** (~120). `chapters::Understanding.interests` becomes `Vec<InterestRef { name, href }>` (`href = "/dashboard/articles?interest=" + encode_component(name)`) with `interests_line()` for the EPUB templates; `_understanding.html` renders `{% for %}…{% if page.is_admin() %}<a href>…` joined by ` · `. Dashboard article detail "Top interests" table, `_signals_table.html`, and the Feeds page "Why" badges link the same way. Existing tests asserting `Matches: Filesystems · Rust` keep passing for non-admin views; add one admin assertion.
+
+8. **Categorizer + job + CLI** (~350).
+   - `interests::categorize(config, db) -> Result<String>`: load uncategorized; if none, return "nothing to categorize"; build `Llms::from_config` with the current taste prompt (as `cmd_profile_rebuild` does) and take `bulk` (fall back to `editor_or_bulk`); one `complete_json` at temperature 0.2 with:
+     ```text
+     TASK: file each new standing interest under one of the reader's interest categories.
+     Existing categories (reuse these names verbatim): <list>
+     Create a new category only when none of the existing ones fits; a new category must be broad enough to hold several interests and named like the existing ones (two to five words, sentence case). Every interest gets exactly one category.
+     New interests: <one per line>
+     Return JSON exactly: {"assignments":[{"interest":"…","category":"…"}]}
+     ```
+     Validate: interest must be one of the batch (case-insensitive), category trimmed, 1–60 chars; unknown names are ignored; anything unassigned stays `NULL`. Log "categorized N (M new categories: …)". Return that as the job message.
+   - `pipeline::build_llms`: after the clients exist, if `interests::uncategorized(db)` is non-empty and a client is available, run `categorize` (warning on error), then rebuild the prompt and the clients exactly as the weekly rebuild path does (the grouping changed). Both the categorizer and the weekly rebuild share that "prompt changed, remake clients" tail.
+   - `jobs::Job::InterestsCategorize` (`interests-categorize`, description "File uncategorized interests under categories with the bulk model, creating new ones only when needed.", `takes_lock` None, not dangerous); `main::run_job` dispatch; catalogue tests.
+   - CLI `daily-epub interests <import|backfill>` in `main.rs`:
+     - `import [--opml PATH] [--profile PATH]` (defaults `data/scour-interests.opml` and `config.profile_path`): parse the OPML with the old `parse_interests` (moved into `interests.rs` as a private helper) and the profile's `## Interests` lines, insert with `add` skipping duplicates, assign each new row's category with `themes::group_into_themes` mapped back per name ("Other standing interests" → `NULL` so the LLM gets a go at them). Print "imported N, skipped M existing, K left for the categorizer".
+     - `backfill`: load every `article_embeddings` row compatible with the configured model/dimension in chunks, load interest vectors from `interest_embeddings` (fetching misses through the service if Voyage is enabled), run `interest_matches` over the whole set (z over the whole cached set stands in for the per-day cohort; say so in the docstring), and `INSERT OR IGNORE` the rows with `run_id NULL` so real-run rows win. Print the row count. Takes the run lock (it writes what the run writes).
+   - Tests: the categorizer with `MockBackend` assigns two interests, creates one new category, ignores a name not in the batch; `import` is idempotent; `backfill` on a two-article fixture writes the expected rows and leaves an existing run-written row alone.
+
+9. **Docs** (~40). README: the "Web site and dashboard" paragraph gets a sentence on Interests; the Commands section gets `interests import` / `interests backfill`; the configuration table gains the three keys and loses `interests_opml`; the Layout section lists `src/interests.rs`. `docs/ideas.md`: strike the "what interests most match" item.
+
+Expect roughly 2 100 lines including tests.
+
+## 8. Verification
+
+- `cargo test`, `cargo clippy`, `cargo fmt` green.
+- Dev seed (`dev/`): `interests import --opml data/scour-interests.opml`, then `interests backfill` (no embeddings in the seed → "0 rows", exits 0), open `/dashboard/interests`: 230 rows, every one categorized except a handful under Uncategorized, weight `—` everywhere; add "Rust macros" → appears uncategorized; **Categorize now** with jobs disabled shows the manual command.
+- After deploy, on the server: run the two commands (§10), open the page, click **Categorize now**, watch the job page, refresh: no Uncategorized left, new categories (if any) look sane. Rate one article from the issue page; its matched interests' weights move on the next refresh with the expected magnitude (`0.5 → 0.67` for a full-strength *loved*).
+- Next morning's run: `explain` on a selected article shows `affinity` present with a weight, or absent with the gate at 0 if fewer than 15 ratings credited an interest (expected at first; the log line says which). The Articles page filtered by an interest the reader knows well returns articles that obviously belong, sorted by cosine; nothing unrelated appears at the bottom of the first page. Dashboard timing for that page stays single-digit ms (`Server-Timing` header).
+- The system prompt on the profile page groups Standing interests by the DB categories with the same members as before the change (byte-stable apart from category names that the LLM added).
+
+## 9. Deferred, with triggers
+
+- **Prompt annotation** of Standing interests with the strongest and weakest weights (e.g. `Rust ↑`, `Coffee ↓`) — once the affinity gate is open and the weights look right for a couple of weeks.
+- **Renaming** an interest in place, and merging duplicates — when the operator actually needs it (delete + add loses nothing but the match rows, which the next runs rebuild).
+- **Match-row retention** — if `article_interests` ever exceeds a few million rows; today it grows ~1 k/day.
+- **Implicit ratings** feeding the weights — already designed for in the curation plan §6.4; nothing here blocks it.
+- **Scour** — the Scour feeds in Miniflux keep working as sources; nothing here syncs interests back to Scour.
+
+## 10. Rollout notes
+
+1. Deploy the binary. **Before restarting the service, delete `interests_opml` from `/etc/daily-epub/config.toml`** (the key is gone and `Config` rejects unknown keys). Migrations run on the first command.
+2. `daily-epub interests import --opml /var/lib/daily-epub/data/scour-interests.opml` (the profile's `## Interests` section is read from `profile_path`; it has been empty so far). Then delete that section from `profile.md`, or leave it — it is ignored either way.
+3. `daily-epub features backfill --rated-only` if any rated article lacks an embedding (it prints the count), then `daily-epub interests backfill`.
+4. Open `/dashboard/interests`, press **Categorize now** for the leftovers, and read the weights: they are live from that moment because they are derived from the existing ratings.
+5. Optional: `daily-epub generate --dry-run` to see `affinity` in a run before the morning.
+
+## 11. Non-goals (do not add)
+
+- A category editor page, category colours, or ordering beyond alphabetical.
+- Per-interest notes, pinning, or manual weight overrides — the weight is derived from ratings only, so the operator changes it by rating.
+- Interest suggestions from articles ("you seem to like X") — a separate feature with its own plan if wanted.
+- Syncing interests to or from Scour, or OPML export.
+- A stored weight column, incremental counters, or a scheduled recompute.
+- Configurable `MATCH_MIN_Z` or match strength curve — constants until there is a reason.
+- Public (anonymous or reader-role) links from the Matches line; the dashboard is admin-only.

+# Shared brief — dashboard tables (2026-09-20)
+
+The operator sees horizontal scrollbars on most dashboard tables, even on an
+ultrawide monitor, because every table is capped at the 80rem page column and
+`min-width: max-content` forbids wrapping. The fix is a small, reusable table
+framework described in **`docs/dashboard-tables.md` — read it first; it is the
+spec.** Two tasks run in parallel in separate git worktrees:
+
+- `01-css.md` — the CSS side (`src/web/tailwind.css`, rebuilt `app.css`).
+- `02-templates.md` — the template audit (every `td` gets the right cell class).
+
+## Ground rules
+
+- Work only in the worktree named in your brief. **Never touch the main checkout**
+  at `/home/thallada/workspace/the-daily-epub`. **Do not `git commit`** (the sandbox
+  cannot write `.git/worktrees`); leave the work in the tree, the orchestrator
+  commits.
+- Styling lives in **`src/web/tailwind.css`** (Tailwind v4, `@apply` inside
+  `@layer components`, semantic colour tokens). After every CSS change run
+  `npm run css` (writes `src/web/static/app.css`, which the binary embeds with
+  `include_str!`). `npm run css:check` must print no diff at the end.
+- CSP forbids inline `<style>`, `<script>` and `style=""` attributes. No new JS,
+  no new dependencies, no table library: this is plain CSS + four cell classes.
+- Keep every hook `app.js` relies on: `table[data-filter]`, `.table-filter`,
+  `input[data-table-filter]`, `.scroll-x` (the filter script does
+  `table.closest(".scroll-x")`), `form[data-confirm]`, `details[id]`, `[data-refresh]`.
+- Keep `cargo fmt`, `cargo clippy --all-targets -- -D warnings` and the tests
+  green (`cargo test --lib web::` while iterating, one full `cargo test` at the
+  end). **Sandbox note:** inside the Codex sandbox `bind()` on 127.0.0.1 is
+  forbidden; ignore every test that fails with `PermissionDenied`/bind errors
+  (about 17 pre-existing ones). Do not "fix" them.
+- 4 cores / 7 GB shared with another agent building Rust at the same time: one
+  cargo process at a time, be patient.
+- KISS / YAGNI: no config knobs, no per-table width tables, no JS resizing, no
+  responsive card-ification of rows. Where the brief and the code disagree,
+  follow the code and note the deviation in your handoff.
+- Finish by writing `docs/plans/briefs/dashboard-tables/handoff-<task>.md`:
+  what changed (file by file), deviations, what you verified and how, anything
+  left open.
+
+## Previewing (optional — the sandbox usually cannot bind a port)
+
+Seed a throwaway database with `cargo run --example seed_dev_db -- ./dev`
+(git-ignored) and serve it with
+`DAILY_EPUB_SERVER__HMAC_SECRET=$(head -c 48 /dev/urandom | base64) DAILY_EPUB_SERVER__BIND=127.0.0.1:<port> cargo run -- --config ./dev/config.toml serve`.
+`measure.mjs` in this directory (needs `playwright` on the module path; a copy
+lives at `~/.npm/_npx/705bc6b22212b352/node_modules`) prints per page and width
+whether the document overflows and which table wrappers scroll. If you cannot
+bind, rely on the router tests and say so; the orchestrator screenshots every
+page at 390/768/1280/1920/2560 after merging.

+# Task 01 — table framework CSS
+
+Worktree: `/home/thallada/workspace/the-daily-epub-tables-css` (branch `tables-css`).
+Read `00-shared.md` and `docs/dashboard-tables.md` first. Only `src/web/tailwind.css`
+and the rebuilt `src/web/static/app.css` change in this task (plus your handoff).
+The template audit happens in a sibling worktree; do not edit templates.
+
+## 1. `.dashboard` becomes a content grid
+
+Replace `.dashboard { @apply mx-auto my-8 max-w-7xl px-4 pb-6 … sm:px-6; }` with a
+grid that keeps the page column pixel-identical to the header
+(`mx-auto max-w-7xl px-4 sm:px-6` = content width `80rem - 2 * gutter`, centred):
+
+```css
+.dashboard {
+  --gutter: 1rem;
+  @apply my-8 grid pb-6 font-sans text-base leading-normal;
+  grid-template-columns:
+    [full-start] var(--gutter)
+    [wide-start] 1fr
+    [content-start] minmax(0, calc(80rem - 2 * var(--gutter)))
+    [content-end] 1fr
+    [wide-end] var(--gutter)
+    [full-end];
+}
+@media (width >= 40rem) { .dashboard { --gutter: 1.5rem; } }   /* Tailwind `sm` */
+.dashboard > * { grid-column: content; min-width: 0; }
+.dashboard > .scroll-x { grid-column: wide; }
+```
+
+Keep `.dashboard > * + * { mt-4 }` and every other `.dashboard …` rule as they
+are (margins on grid items work). Verify in the templates that nothing relied
+on the old padding: `.save-bar` uses `-mx-4 sm:-mx-6` to bleed to the edges;
+under the grid it still overflows its `content` area into the gutter columns
+by the same amount, so leave it unless you see a problem. The `sm` breakpoint
+is `40rem` in Tailwind v4 and `@media` rem is always 16px-based, so the query
+above matches `sm:` exactly.
+
+Prototype measured in Chromium and Firefox at 390/1280/2560: `h1` left edge and
+width identical to today, no document overflow, table centred and wider than
+the column only when its content needs it.
+
+## 2. Tables shrink by wrapping; page-level tables may grow past the column
+
+- Delete `.scroll-x > table { min-width:max-content; }`.
+- Add, for the wide wrapper only:
+
+```css
+.dashboard > .scroll-x > table {
+  width: auto;                                   /* shrink-to-fit */
+  min-width: min(100%, calc(80rem - 2 * var(--gutter)));
+  max-width: 100%;
+  margin-inline: auto;
+}
+```
+
+  A table narrower than the page column fills the column as today; a wider one
+  grows, centred, to the viewport edge; the wrapper scrolls only past that.
+  Tables that are not direct children (cards, disclosures, signal tables inside
+  cells) keep `w-full` from the base rule and simply wrap, then scroll.
+
+## 3. Cell vocabulary (exactly four classes, see the doc's table)
+
+- `.num` → `@apply text-right tabular-nums;` and `td.num { @apply whitespace-nowrap; }`.
+  Header cells with `.num` may wrap ("cache write", "matched articles").
+- `.cell-tight` unchanged (`whitespace-nowrap`).
+- `.cell-wrap` → `@apply min-w-[10rem] max-w-[32rem] whitespace-normal; overflow-wrap:anywhere;`
+  (ceiling raised from 24rem so titles get a single line when the screen has
+  room; `max-width` on a cell is honoured by Chromium and Firefox for the
+  column's max-content contribution — measured).
+- `th` keeps wrapping (no nowrap); keep the sticky `thead`.
+- `td > pre.preview { max-w-md }` and `.rating-cell` rules stay.
+
+## 4. Small things to keep honest
+
+- `.prose-body table` (reader pages) keeps its own rules; do not touch.
+- Put a short comment above the table rules pointing at `docs/dashboard-tables.md`.
+- `npm run css`, then `cargo build` (the binary embeds app.css) and
+  `cargo test --lib web::`. Router tests assert on markup, not on these rules,
+  so nothing should break; if something does, say what and why in the handoff.
+- If you can run the dev server + `measure.mjs`, do it and paste the ≥1280 lines
+  for `/dashboard/articles`, `/dashboard/runs` and `/dashboard/runs/1` into the
+  handoff. With unchanged templates some tables will still scroll at 1280 —
+  that is expected until the template audit lands — but at 2560 the articles
+  and candidates tables must fit without scrolling.

+# Task 02 — template audit: every cell says what it holds
+
+Worktree: `/home/thallada/workspace/the-daily-epub-tables-tpl` (branch `tables-tpl`).
+Read `00-shared.md` and `docs/dashboard-tables.md` first. Only files under
+`src/web/templates/` change in this task (plus your handoff). The CSS lands in a
+sibling worktree; assume the four cell classes behave exactly as the doc's
+table says (`cell-wrap` floor 10rem / ceiling 32rem with `overflow-wrap:anywhere`,
+`cell-tight` nowrap, `td.num` nowrap right-aligned, unclassed cells wrap at
+spaces, `th` always wraps, page-level tables grow past the page column when
+their content needs it).
+
+Go through every `<table>` in `src/web/templates/dashboard/*.html`,
+`src/web/templates/_candidate_row.html` and `src/web/templates/_signals_table.html`
+and apply these rules to each `td`:
+
+1. **`cell-tight` only on timestamps, dates, ids and single tokens ≤ ~20
+   characters** (`first_seen`, `when`, `started`, `finished`, `requested`,
+   `created`, `last_login`, `saved_at`, `changed_at`, `event_at`, `issue_date`,
+   `published`, `run.date`, `run.funnel` "310 → 200 → …", `age → decay`,
+   `#id`). **Remove it** from feed names/titles (`article.feed`, `candidate.feed`,
+   `miss.feed`, `row.feed_credits`, nearest-article `feed`), reasons
+   (`article.reason`, `row.reason`, `candidate.reason`), "admitted by" cells,
+   usernames / `requested_by` / `saved_by`, roles, sources, kinds, job names,
+   and from any cell that combines a badge with more text (stage + run date).
+   A `.badge` is already `whitespace-nowrap` on its own, so a badge-only cell
+   needs no class.
+2. **`cell-wrap` on every free-form column**: titles, URLs, notes, messages,
+   "reason or comment", facet values, badge lists (interests), config diff
+   before/after, anything a user typed. Keep it where it already is.
+3. **`num` on numbers only** (it already is; just make sure no text column
+   uses it because it wanted right alignment — `#id` cells may keep `num`).
+4. **Long text that should not stretch a row**: if a column can hold hundreds of
+   characters (job `message`, rating-import `message`, `note`), keep
+   `cell-wrap` and wrap the text in `<div class="line-clamp-3" title="{{ … }}">`
+   **only** if the full text is reachable somewhere else on the page or via the
+   `title`; otherwise let it wrap. Never put `truncate`/`line-clamp-*` on a `td`.
+5. **`dashboard/feeds.html`**: drop `table-fixed` (fixed layout is ignored once
+   the page-level table is `width:auto`). Keep the `w-*` hints on the `th`s
+   (they act as minimums under auto layout), keep the `line-clamp-*`/`truncate`
+   inner elements — they already sit on block children, which is the pattern —
+   and put `cell-wrap` on the Feed and Why cells if it is not there. The
+   actions cell keeps its forms; give it `cell-tight` only if the buttons wrap
+   badly, otherwise leave it unclassed.
+6. **`dashboard/run.html` Feeds card** (`<table class="table-fixed">` inside
+   `.card`): this table is `w-full` inside a card, so `table-fixed` still works
+   there; leave it, but it is the only allowed `table-fixed`.
+7. **Header cells**: remove nothing, but make sure no `th` has `whitespace-nowrap`
+   or `cell-tight`; long headers such as
+   "considered → eligible → triaged → assessed → shortlisted → selected" may wrap.
+8. **Wrappers**: every page-level table (more than a handful of columns:
+   runs, candidates, articles, ratings current/events, interests, feeds, users,
+   jobs, stats runs/costs, settings history, profile versions, near misses,
+   funnel) must sit in a `<div class="scroll-x …">` that is a **direct child**
+   of `<section class="dashboard …">` — check that no such wrapper is nested in
+   a stray `<div>`; tables inside `.card`/`.cards`/`details` stay where they are.
+   Keep `tall` where it is today.
+
+Do not change the columns themselves, their order, the text, or any
+`data-*`/`id`/`name`/`action`/`aria-*` attribute. Do not touch reader/public
+templates (`issue_*.html`, `article.html`, `world.html`, `behind.html`, `_toc.html`).
+
+Verify: `cargo test --lib web::` (router tests assert on text and some class
+names; if one breaks only because a class moved, update the test and say so),
+then `cargo fmt`/`clippy`. List in the handoff, per template, which cells lost
+`cell-tight`, which gained `cell-wrap`, and any clamp you added.

+    `content`/`wide` grid and 1rem/1.5rem gutter variable.
+  - Let direct-child `.scroll-x` wrappers occupy the wide track and made their
+    tables shrink-to-fit between the content-column floor and wrapper ceiling.
+  - Removed the global `.scroll-x > table { min-width:max-content; }` rule.
+  - Kept `.num` alignment/tabular figures on headers and cells, while limiting
+    nowrap to `td.num`.
+  - Raised `.cell-wrap`'s maximum width from 24rem to 32rem.
+  - Added a pointer from the table rules to `docs/dashboard-tables.md`.
+- `src/web/static/app.css`
+  - Rebuilt from the Tailwind source and checked for reproducibility.
+
+No templates, JavaScript, reader table rules, preview rules, or rating-cell
+rules changed.
+
+## Generated CSS diff audit
+
+Compared committed and rebuilt CSS one closing brace per line with:
+
+```sh
+diff -U0 \
+  <(git show HEAD:src/web/static/app.css | tr '}' '\n') \
+  <(tr '}' '\n' < src/web/static/app.css)
+```
+
+The 177-line diff contained 111 removed and 12 added content lines (excluding
+the two diff file headers). The component-rule changes were exactly the table
+framework changes above: remove `.scroll-x > table`, replace `.dashboard`, add
+the three direct-child dashboard selectors, split `td.num` nowrap from `.num`,
+and change `.cell-wrap` from 24rem to 32rem. The remainder was removal of
+utilities, unused theme symbols, and supporting custom properties that had
+previously been emitted by repository-wide automatic source discovery. There
+were no unrelated added selectors.
+
+The rebuilt file shrank from 77,721 to 70,697 bytes. The documentation-only
+utility selectors `.line-clamp-3`, `.max-w-[32rem]`, `.min-w-[10rem]`, and
+`.pb-6` are absent. The semantic `.cell-wrap` component still contains
+`min-width:10rem` and `max-width:32rem`, and `.dashboard` still contains its
+requested `padding-bottom` declaration.
+
+## Verification
+
+- `npm run css` — passed.
+- `npm run css:check` — passed with no diff.
+- `cargo build` — passed after the final CSS build.
+- `cargo test --lib web::` — 135 passed; the two failures were
+  `web::dashboard::feeds::tests::a_duplicate_subscription_still_decides_the_row`
+  and `web::dashboard::feeds::tests::add_subscribes_and_records_the_miniflux_feed_id`.
+  Both failed at the test bind setup with the documented
+  `PermissionDenied` / `Operation not permitted` sandbox error.
+- `cargo fmt` — passed without changes.
+- `cargo clippy --all-targets -- -D warnings` — passed.
+- `git diff --check` — passed.
+
+An extra full `cargo test` required by the shared brief was attempted, but the
+filesystem ran out of space while creating another test archive before tests
+started. I removed only this package's generated artifacts with
+`cargo clean -p daily-epub` (2.0 GiB), then reran the complete user-requested
+command sequence above successfully. The full suite remains unverified; the
+focused web suite is verified subject only to the two allowed bind failures.
+
+## Deviations and open items
+
+There are no implementation deviations. I did not run the browser measurement
+script because the sandbox cannot bind a preview server, as independently
+confirmed by the focused test failures. Visual viewport measurement remains for
+the post-merge environment described in the shared brief.

+# Dashboard tables template handoff
+
+Implemented `02-templates.md` against `00-shared.md` and
+`docs/dashboard-tables.md`. No columns, content, hooks, or attributes were
+changed. The existing page-level `.scroll-x` wrappers already had the required

+| `dashboard/stats.html` | Runs status | None | None |
+| `dashboard/users.html` | None | None | None |
+
+`dashboard/feeds.html` also lost page-level `table-fixed`; its existing header
+width hints and inner Feed/Why clamps remain. The card-local `table-fixed` feeds
+table in `dashboard/run.html` remains as specified.
+
+## Deviations
+
+None. Templates whose cells were already compliant were left unchanged.

+## Verification
+
+- `cargo test --lib web::`: 135 passed; two Miniflux mock-server tests failed

+//! Preview an article the way the Xteink X4 will show it.

+//! Browsers are a poor stand-in for the X4: its pages are rendered ahead of
+//! time by the XTC converter's CREngine, which has its own defaults (`code` is a
+//! block, `pre` has no margin) and only four grey levels. This builds both
+//! EPUB editions around one article, runs the real converter on the X4 one and
+//! decodes every page to `page-NNN.png`.
+//!
+//! ```text
+//! cargo run --example x4_preview -- <article URL | HTML file> <out dir>
+//! cargo run --example x4_preview -- --convert <x4.epub> <out dir>
+//! ```
+//!
+//! A URL goes through the real extraction path; an HTML file is used as the
+//! stored body as-is. `--convert` skips the build, for iterating on a
+//! stylesheet inside an unzipped EPUB. Needs the converter at
+//! `/opt/epub-to-xtc-converter` and runs it with `xtc-settings.example.json`.

+//! BookOrbit OPDS catalog lookup support.
+//!
+//! BookOrbit is the companion library and browser-based EPUB reader used by
+//! this service. Its OPDS catalog is preferable to its JSON API here because
+//! OPDS uses static HTTP Basic credentials and therefore needs no JWT/refresh
+//! token lifecycle. Searches use `/api/v1/opds/catalog?q=<date>`, acquisition
+//! links expose `/api/v1/opds/<book_id>/download?fileId=<file_id>`, and browser
+//! links use `/read/<book_id>/<file_id>`. See
+//! `docs/plans/2026-09-05-bookorbit-read-link.md` for the integration design.

+//!   language hint the page carries (`language-rust`, Rouge's wrapper `<div>`,

+//!   article page and both EPUB editions. Blocks with a hint use it; blocks
+//!   without one are guessed from their content ([`guess_language`]), and
+//!   anything not confidently code is left exactly as it was.
+//!
+//! Tokens come out as flat `<span class="hl-…">` elements, one class each, so
