Merge pull request 'fix: series removal sent its status line twice' (#176) from fix/series-remove-double-writeheader into main

adminSeriesRemove answered the list surface with two h.render calls -- the
row fragment and the out-of-band heading -- and h.render writes a status
line each time, so every removal logged "superfluous
response.WriteHeader call". The heading is an append to a response
already committed, so it now executes straight onto w, the way
writeChromeOOB already does it.

The regression test runs the router under a real server with a captured
ErrorLog: a ResponseRecorder never sees this warning, which is why the
existing removal test did not catch it.

This repo's forge is self-hosted Gitea driven by `tea`, not GitHub.
+---
+
+# Gitea, not GitHub
+
+`origin` is the self-hosted Gitea instance `gitea.violetcrown.my.id`, repo
+`sulthan/mangaBookmark`. Everything past plain git goes through
+[`tea`](https://gitea.com/gitea/tea) (0.14.2 on this machine).
+
+**`gh` is not installed**, so the harness's `issue://<n>` and `pr://<n>` URIs
+error out (`GitHub CLI (gh) is not installed`, measured 2026-08-17). There is no
+fallback to add — read tickets with `tea`.
+
+`tea` infers the repo from `origin`; auth lives in `tea login`, never a
+`GH_TOKEN`. Your Gitea username comes from `tea login list` — `tea` has no `@me`.
+
+Flags are the environment's job: run `tea <command> --help` rather than trusting
+a remembered flag. This file carries only what `--help` will not tell you.
+
+## Commands
+
+| Job | Command |
+|---|---|
+| Read | `tea issue <n> --comments` / `tea pr <n> --comments` — `--comments` is not optional |
+| List | `tea issue list --state open\|closed\|all -o json --fields index,title,body,labels,state,author` |
+| Search | `tea issue list -k "<keyword>" -L "<label>" -A "<author>"` (`-K all` also searches PRs) |
+| Create | `tea issue create -t "..." -d "..."` (`-L`, `-a` optional) |
+| Comment | `tea comment <n> "..."` |
+| Label | `tea issue edit <n> --add-labels "..."` / `--remove-labels "..."` |
+| Close | `tea issue close <n>` / `tea pr close <n>` |
+| PR | `tea pr create --head <branch> --base main -t "..." -d "..."`, `tea pr checkout <n>`, `tea pr review <n>`, `tea pr merge <n>` |
+
+## Traps
+
+- **A bare read is a truncated read.** Without `--comments`, `tea issue <n>` and
+  `tea pr <n>` print the opening body and drop every comment silently — no
+  prompt, no marker, no hint that more exists (measured 2026-08-17: issue #123
+  prints 40 lines bare, 132 with `--comments`). The comments are where the
+  decisions live and the body is usually the stalest part of the ticket, so
+  **every read that exists to understand an issue or PR passes `--comments`**,
+  and understanding means body plus all comments plus whatever ticket they point
+  at. Comment count is `tea issue list --fields index,comments`, so a read that
+  shows fewer than that is incomplete. A PR's review comments are a second
+  stream: `tea pr review-comments <n>`.
+- **One index space for issues and PRs.** A bare `#42` may be either: try
+  `tea pr 42`, fall back to `tea issue 42`. Say which one you found.
+- **Output is rendered boxes**, not plain text. Anything you parse needs
+  `-o json`, plus `--fields` to keep the payload small. `tea pr create` prints
+  the PR URL on its last line.
+- **`close` takes no `--comment`.** Comment with `tea comment <n>`, then close.
+- **Gitea will not auto-create a label.** `tea labels list` first; missing one
+  gets `tea labels create --name "..." --color "#rrggbb"` before the `edit`.
+- **Multi-line bodies go through a heredoc**, never inline escapes:
+  ```bash
+  tea issue create -t "Title" -d "$(cat <<'EOF'
+  body line one
+
+  - acceptance criterion
+  EOF
+  )"
+  ```
+- **No sub-issue and no dependency command.** Gitea's API has issue
+  dependencies, `tea` does not expose them, so parentage and blocking live as
+  body lines — the shapes are in `docs/agents/issue-tracker.md`.
+
+## Conventions this repo layers on top
+
+Ticket bodies, wayfinding issues, and the PR-as-request-surface flag:
+`docs/agents/issue-tracker.md`. Triage label strings: `docs/agents/triage-labels.md`.
+A label named there still has to exist in the tracker before `--add-labels`.
+
+Finish a forge action by stating the number you touched and its state after —
+"commented and closed #71" — so the write is checkable without a second query.

+Ticket source and tracker conventions: `docs/agents/issue-tracker.md`. `tea` usage: skill `gitea`.
 
-## 1. Collect the tickets
+## 0. Load the plan
 
-The user's argument is the selector: issue numbers, a label, a parent issue, or
-nothing. With nothing, take the open issues labelled `ready-for-agent`.
+Your argument is the batch slug. Read `.scratch/<batch-slug>/plan.md` — it gives
+the base branch, the waves, the contracts, and each ticket's brief path and
+status. Run the earliest wave that is not landed.
 
-Fetch each with `tea issue <n> --comments`, and read the **whole** body —
-acceptance criteria and the `Blocked by` line are what the rest of this skill
-runs on. A ticket whose blockers are still open is out of this batch unless a

+The briefs are the requirements and they are already approved: read each one you
+are about to dispatch, but do not rewrite it, and do not fetch the tickets from
+the tracker to second-guess it. A brief that is wrong or thin is a `plan-tickets`
+problem — say so and stop, rather than patching it here.
 
-## 2. Plan the batch
+No plan file, or no briefs for the next wave: run `plan-tickets` first. That
+skill owns wave membership, contracts, and every brief.
 
-Explore enough of the codebase to write briefs a fresh context can act on: the
-files each ticket lands in, the patterns it must follow, the `AGENTS.md`
-invariants it touches.
-
-Then decide three things:
-
-- **Waves.** Blocking edges set the order; tickets with no open blocker inside
-  the batch share a wave. Cap each wave at **3** concurrent tickets unless the
-  user set another width.
-- **Contracts.** Two tickets in one wave that meet at a function signature, a
-  JSON shape, a table column, or a token name: you decide the shape now and
-  write the identical wording into both briefs. A contract left for the
-  subagents to negotiate is a merge conflict you scheduled.
-- **Splits.** A ticket too big for one fresh context window goes into the wave
-  as two briefs, or back to the user.
-
-## 3. Get the plan approved
-
-Present, and stop:
-
-- the wave list, and for each ticket: number, title, one-line brief summary,
-  the files or areas it will touch, its verification commands
-- every cross-ticket contract, verbatim as it will appear in the briefs
-- anything you had to assume
-
-Wait for approval. Apply the user's edits to the plan, do not relitigate them.
-
-## 4. Run a wave
+## 1. Dispatch the wave
 
 Per ticket, before dispatch:
 
 ```bash
-git worktree add ../ticket-<n> -b ticket/<n>-<slug> <base>   # base = the branch you are on
+git worktree add ../ticket-<n> -b ticket/<n>-<slug> <base>   # base = the plan's base branch, checked out here

+# Plan tickets
+
+You produce the two artifacts the `implement-tickets` skill runs on: a **plan
+file** and one **brief** per ticket in the next wave. You write no ticket code
+and create no worktrees — that is the runner's half.
+
+Ticket source and tracker conventions: `docs/agents/issue-tracker.md`. `tea` usage: skill `gitea`.

+Called twice in a batch's life, at least: once to open it, then again after each
+wave lands, because a later wave's briefs may need what the last one changed. On
+a re-entry, read the existing `.scratch/<batch-slug>/plan.md` first and plan only
+the next unlanded wave — the waves and contracts already approved there stand
+unless the landed wave proved one wrong.
+
+## 1. Collect the tickets
+
+The user's argument is the selector: issue numbers, a label, a parent issue, or

+the same way: nothing on the implementation path reads the tracker after you —
+only `cr-spec` does, at review time — so a decision that lives in a comment
+reaches the implementer only if you carry it into the brief.
+
+## 2. Plan the batch
+
+Explore enough of the codebase to write briefs a fresh context can act on: the
+files each ticket lands in, the patterns it must follow, the `AGENTS.md`

+
+Pick a `<batch-slug>` — short, from what the batch is about — and write

+`planned` | `dispatched` | `landed` | `handed back`. Every ticket in the batch,
+including waves not briefed yet.
+
+**Contracts.** Each cross-ticket contract verbatim, naming both ticket numbers.
+
+**Assumptions.** What you had to assume, and what the user corrected at approval.

+
+**Decisions.** Whatever the ticket's comments or its parent spec settled that

 - **The CDP browser must look like a real browser, and stock headless images don't.** Measured 2026-08-08 against kagane.to, all from the same IP: `chromedp/headless-shell:stable` never cleared the challenge in 90s (`navigator.webdriver` true, empty plugin list, Chromium-branded client hints — suppressing `webdriver` alone changed nothing); `zenika/alpine-chrome` ships Chrome 124, refused outright; real Chrome with the default `--headless=new` UA never cleared, because the UA says `HeadlessChrome`; real Chrome with a stock UA **and** a non-UTC clock zone cleared in ~4s. Hence `chrome/` — a Debian image with `google-chrome-stable`, a version-derived UA, and `TZ`/`BROWSER_TZ`. Chrome reads the zone *name* through ICU from `/etc/localtime`'s symlink target, ignoring the file's contents, so mounting the host's `/etc/localtime` does **not** work; `/etc/timezone` is mounted instead.

 - **UTC is the tell, not a country mismatch.** A UTC clock is the datacenter default, and the challenge refuses it; any real zone clears. Measured 2026-08-08, identical container, one Indonesian egress IP: UTC never cleared in 60s (twice), while `Asia/Jakarta` **and** `America/New_York` both cleared in 4s. An earlier note here claimed the zone had to match the egress IP's country — that was wrong, inferred from the host clock (`Asia/Bangkok`) rather than the measured egress. A second earlier claim, that Cloudflare "scores" a UTC clock, was also wrong: the measurement is real but the mechanism is not documented anywhere — Cloudflare publishes no timezone signal, and free-plan zones carry no score at all. `BROWSER_TZ` therefore needs a plausible zone, not a geolocated one.
 - **A challenged page needs the tab kept open.** The interstitial takes seconds to solve and only then writes clearance into the browser's shared cookie jar. Navigate-read-close never clears anything; `BrowserFetcher.run` holds one tab and re-reads until the payload arrives.

-- **Schema is migration-owned.** `internal/store/migrations/*.sql` is
-  `go:embed`-ed and applied on every start by `store.migrate`: one numbered
-  file per change, one transaction each, versions recorded in
-  `schema_migrations`. Files are **append-only** — editing an applied one
-  changes nothing on a database that already ran it. No column probing, no
-  data-fixup migrations: both were SQLite-era machinery and are gone.
-- **Tests need Docker.** `internal/pgtest` starts one `postgres:17-alpine`
-  container per test binary (`TestMain` -> `pgtest.Main`) and hands each test
-  its own database (`pgtest.URL(t)`). A package whose tests touch the store
-  must have that `TestMain`.
-- **Reader-owned store, four tables.** `readers` is keyed by Discord user ID
-  and carries the SHA-256 of the Reader's userscript credential plus a
-  `token_epoch` (issue #24). Credentials are derived, never stored: `token.Token(TOKEN_KEY, discord_id, epoch)` (HMAC, `internal/token`), and only its SHA-256 sits in `readers.token_sha256`, so install URLs can be rebuilt after any restart while a database leak yields nothing but hashes. The seed creates the **owner** row at startup; its epoch-0 hash is refreshed on every start **only while the row has never been rotated**, so a restart can never resurrect a rotated-away credential. Every other row is created by that Reader's own first login (`Store.EnsureReader`, idempotent on `discord_id`, and it never rewrites an existing row's hash). Rotation is `Store.RotateToken` (epoch bump + hash rewrite in one transaction), driven by the web UI.
-  `series` keyed `(site, series_id)`
-  (`asura`|`demonic`|`comix`|`kagane`|`novelfull`|`lightnovelworld`) owns the
-  shared facts — title, cover, canonical URL, `kind` (`manga`|`novel`),
-  Latest Chapter, `latest_checked_at`, and the Sighting pair
-  `latest_sighted_at`/`latest_raised_by` (issue #103) — and `bookmarks` holds only what
-  differs between readers: progress, favourite, lifecycle bucket,
-  `updated_at`. A bookmark is keyed `(reader_id, site, series_id)` — no
-  surrogate id; the wire `key` is derived as `site:series_id` on read — and
-  every store read/write is scoped to the reader it names. Auth resolves the
-  acting Reader from the presented credential (`httpmw.Auth`) and nothing
-  else — there is no unauthenticated-by-Reader route and no global token; the
-  reader id travels in the request context. Sync **last-write-wins**; the wire format
-  stays flat (ADR-0004). `Store.Upsert` decomposes one flat body across two
-  tables and enforces the ownership rule: client `title`/`series_url`/`cover`
-  are written only when the series row is new (ADR-0003).
-- **Endpoints:** `GET /bookmarks`, `PUT /bookmarks/{key}` (upsert; see `updated_at` rule below), `DELETE /bookmarks/{key}`, `GET /healthz` (no auth).
-- **Web UI:** same binary serve the browser UI on a second
-  hostname — `GET /` (list, or login page when no session),
-  `GET /auth/discord` + `GET /auth/discord/callback` (Discord OAuth,
-  ADR-0002), `POST /logout`, `GET /static/*`, htmx fragment endpoints
-  under `/ui/*`. Templates + assets `go:embed`-ed under
-  `backend/internal/web/`, so `backend/Dockerfile` must copy the whole
-  `internal/` tree, not just `*.go`. Sessions are rows in the `sessions`
-  table: the cookie carries only an opaque id, looked up (and expiry-
-  checked) on every request, and deleting the row revokes the session.
-  Guild membership *is* registration (issue #27): `discordCallback` gates on
-  membership (and `DISCORD_REQUIRED_ROLE` when set) and then calls
-  `Store.EnsureReader`, so a refusal creates nothing and a returning Reader
-  reuses their row. The owner is the only Reader with administrative reach:
-  `POST /readers/{id}/revoke` (404 for anyone else) drops that Reader's
-  sessions, and the `readers` panel renders only on the owner's page.
-  A Reader with no bookmarks at all sees `listView.Fresh`, whose empty state
-  offers both install links instead of describing a filter.
-  UI mutations read-modify-write
-  through `Store.Get` + `Store.Upsert` so `updated_at` rule stays one
-  place. See `docs/superpowers/specs/2026-07-25-web-ui-design.md`.
-  **Design-tool caveat:** templates link `/static/style.css` root-absolutely
-  (correct — served from `/`), but impeccable detector resolves
-  stylesheet href with `path.resolve(fileDir, href)`, drops directory
-  on leading `/` and silently skip file. Relative href don't help
-  either: template's directory isn't its served path. So
-  `detect.mjs backend/internal/web/templates` reports **false clean** —
-  always pass `backend/internal/web/static` too. One finding there,
-  `overused-font` on "Instrument Serif", deliberate identity choice, not debt.
-- **Every action that moves series out of list is confirm-gated.**
-  Archive, finish, remove each open own `.confirm-row` disclosure
-  (`toggleConfirmRow(key, kind)` in `filter.js`, `kind` ∈
-  `archive|finish|remove`); restore fire instantly since it's the reversal.
-  Remove's row wear ember wash, two reversible ones wear `.calm` grey.
-  `--ember` stay reserved for new-chapter signal: busy bar and inline
-  error use `--mute`.
-- **Latest-chapter poller:** one goroutine per Site (a Poll Lane, issue #100),
-  each re-checking that Site's bookmarked series' newest published chapter from
-  backend's own network access, so `latest_chapter` stays fresh when the user
-  isn't browsing. Second, parallel signal — the userscript keeps its own
-  `maybeCaptureLatestOnSeriesPage`/`backgroundRefreshLatest` schedule, and its
-  `reportLatestChapter` PUTs every read, unchanged numbers included, because an
-  unchanged read is exactly the Sighting worth deferring a Poll on (#103).
-  Two independent clocks: per-series rest (`series.latest_checked_at`,
-  enforced by `Store.DueForLatestCheck`'s WHERE clause — `now - Rest`) and
-  per-Lane gap (the Lane sleeping between fetches, `effectiveGap`). Both live
-  in the Site registry (`internal/latest/sites.go`), not config: the five env
-  knobs that used to size a shared pace are gone.
-  The poller walks **Series, not Bookmarks** — a series referenced by several
-  bookmarks is fetched once per cycle, and the due queue orders
-  `reader_count DESC, latest_checked_at ASC` (ADR-0003). Series row stamped
-  *before* fetch so broken series wait out the rest instead of retrying
-  every tick; found chapter written straight to the series row via
-  `Store.SetLatestChapter`, so a bookmark's `updated_at` — and the list
-  order — is never touched.
-  **Sightings** (issue #103, ADR-0011) let a Reader's own page read defer a
-  Poll: `Store.RecordSighting` — called by the PUT handler *before* the Upsert,
-  because the raise test needs the row as it stands — stamps
-  `series.latest_sighted_at` and, when the report raises the stored number,
-  names its Reader in `series.latest_raised_by`. The due query's HAVING clause
-  is where deferral lives: a Series is skipped only while it has exactly one
-  Bookmark, was sighted within one Rest, and is under the ceiling
-  (`sightingCeilingRests`, six of that Site's rests) since its last Poll. So a
-  shared Series is never deferred, and no Series goes six hours unpolled
-  whatever arrives. `checkOne` judges the named Reader off the comparison it
-  already makes: a lower number is a contradiction (logged with the Reader and
-  both numbers), the same number an agreement, a higher number the Site
-  publishing and neither — that last one clears the attribution instead, since
-  the value the Poll then stores is its own and a later retraction is not the
-  Reader's fault. Three contradictions
-  (`store.SightingDisagreementLimit`) stop that Reader deferring — their
-  reports still write the Latest Chapter — and twenty consecutive agreements
-  (`store.SightingAgreementsToClear`) forgive them, as does the owner's
-  clear-marks control. Deferral is recomputed from live facts every round, so
-  nothing needs invalidating when a Series gains a second Bookmark; the one
-  input read earlier is the Reader's marks, checked when the Sighting is
-  recorded, so crossing the threshold or being cleared takes effect from that
-  Reader's next Sighting and the standing already bought lasts out its rest.
-  Refusals and browser loss are Lane-local: two `errChallengeHeld` in one pass
-  stop that Site for `refuseBackoff` (15m) while other Lanes continue; an
-  `errBrowserInterrupted` (remote Chrome restart) sets a shared Poller flag
-  that makes the other browser Lanes skip their passes for the same 15m, so a
-  restarting Chrome doesn't stamp one Series per Lane per pass — after the
-  window the flag decays and they probe again. Browser Lanes wake Chrome only
-  when 5+ Series are due or one has waited 15m (ADR-0005 on-demand browser),
-  and cover work (both healing a stored source URL and filling a blank from
-  the series page) runs in the background so a slow CDN can't consume a
-  Lane's gap.
-  A refusal is only ever the challenge *page*: `isInterstitial` matches the
-  orchestration path `/cdn-cgi/challenge-platform/h/`, never the bare prefix.
-  Cloudflare injects `/cdn-cgi/challenge-platform/scripts/jsd/main.js` into
-  ordinary 200 pages once a zone turns JS detections on, which demonic did on
-  2026-08-16 — the prefix match then read every real demonic page as a refusal
-  and parked that Lane in 15m backoff while plain TLS was returning the full
-  series page.
-  Fetches use `bogdanfinn/tls-client` with Chrome profile as defence in depth
-  against fingerprint-based blocking; any failure log and skip. kagane, comix
-  and novelfull sit behind Cloudflare JavaScript challenges the TLS client
-  can't clear, so they are fetched over CDP via `BROWSER_WS_URL`; kagane and
-  comix are simply not polled when that's unset, while novelfull falls back to
-  a plain-TLS attempt — its challenge is a live time-varying fact, and its
-  cover bytes never need the browser. comix's browser read is an in-tab
-  `fetch()` of the Series URL, not a DOM render: it is an SPA, so rendering
-  costs ~65 requests for the same server-rendered HTML one fetch returns
-  (measured 2026-08-12, issue #98). See
-  `docs/superpowers/specs/2026-07-26-server-latest-chapter-polling-design.md`.
-  The poller's series write is a single-column UPDATE
-  (`Store.SetLatestChapter`), not a read-modify-write of the whole bookmark:
-  it cannot revert read progress or move `updated_at`, so the old
-  stale-re-read race is gone with the Get+Upsert flow.
-- **Covers are acquired at creation, then served from our own origin
-  (ADR-0007):** the first Bookmark of a Series fires `Store.OnSeriesCreated`,
-  which `latest.Acquirer` turns into one series-page fetch yielding both the
-  Latest Chapter and the cover URL; the bytes then go through
-  `latest.CoverBytesFetcher` into `Store.SetSeriesCover`. It runs in a
-  goroutine — the Reader's PUT must neither block on a Site nor fail with one
-  — and every failure is logged and dropped, leaving the Bookmark intact. The
-  wire's `cover` is the absolute `PUBLIC_BASE_URL + /covers/{sha256}` once
-  bytes exist and `""` before, never an address that 404s. `GET /covers/{addr}`
-  is public and uncredentialed: the userscript renders it on a Site's origin,
-  where no cookie or token of ours travels. A client-sent `cover` is decoded
-  and discarded, permanently (ADR-0004 compatibility).
-  Browser-backed Sites join the same pipeline (issue #62, extended to comix by
-  #98): kagane and comix pages *and* cover bytes go through the browser sidecar
-  (nothing falls back to a plain fetch, which would only retrieve a challenge
-  page), while novelfull needs the browser only for its HTML — the cover URL
-  comes out of the browser-fetched page and the bytes go over plain TLS. With
-  no browser configured, kagane and comix Covers are simply absent; novelfull
-  still gets one — at creation and on the poll — when its page body happens to
-  answer a plain request (the challenge is a live time-varying fact). comix
-  cover bytes must arrive by direct navigation, not an in-page fetch: its
-  Series page sets `cross-origin-embedder-policy: require-corp`, which fails a
-  page-context fetch of `static.comix.to`. The old kagane-only
-  serving path (`/img/kagane/{id}`, template rewrite, `CoverFetcher`) is gone
-  (issue #63): the one public route serves every Site.
-- **`updated_at` drives list order, so moves only on real reading progress:** server apply its timestamp when row new or `last_chapter_num` changes, else keep stored value — favouriting series or recording newly published chapter must not reorder list. `PUT` therefore returns row **as stored**, clients must adopt that response rather than own payload. See `plans/2026-07-25-bookmark-list-favorites-design.md` §4.
-- **Lifecycle buckets:** `status` on each bookmark is `reading` | `archived` |
-  `finished`, orthogonal to `favorite`. Archived and finished appear only in
-  own tab — not in All, Updated, Favourites, or recent strip. Poller keeps
-  checking archived series and skip finished ones. `finished` settable
-  only from web UI; `PUT /bookmarks/{key}` reject it with 400.
-  **Empty incoming status means "keep stored one"** — resolved on the
-  `VALUES` side of `Store.Upsert`, not conflict clause, since
-  `excluded.*` is post-evaluation row and default applied there would
-  wipe bucket on every PUT from client that predates column. See
-  `docs/superpowers/specs/2026-07-27-status-buckets-design.md`.
-- **Config via env:** `TOKEN_KEY` (derives every Reader's userscript credential;
-  required), `OWNER_DISCORD_ID` (seeds the owner Reader — the administrator and
-  the owner of every pre-registration bookmark; required),
-  `ALLOWED_ORIGINS` (comma list),
-  `DATABASE_URL` (Postgres connection URL, required — no default),
-  `COVER_DIR` (required filesystem volume for content-addressed Cover bytes),
-  `PUBLIC_BASE_URL` (required origin this deployment answers on, trailing
-  slash trimmed; every Cover URL on the wire is built from it, absolute
-  because the userscript renders on a Site's origin — ADR-0007),
-  `PORT` (default `8080`), `DISCORD_CLIENT_ID`/`_CLIENT_SECRET`/`_GUILD_ID`/
-  `_REDIRECT_URI` (required; Discord OAuth for the browser UI),
-  `DISCORD_REQUIRED_ROLE` (optional role gate, empty by default),
-  `DISCORD_API_BASE` (default `https://discord.com/api/v10`),
-  `LATEST_CHAPTER_POLL_ENABLED` (background latest-chapter poller kill
-  switch, default on). Pace is per Site in the registry (issue #100): every
-  Site rests an hour and gaps ten seconds, a Site with more eligible Series
-  than 360 tightens its own gap toward the 1s floor, and browser Lanes wake
-  Chrome only on demand (ADR-0005). The `_COOLDOWN`/`_BROWSER_COOLDOWN`/
-  `_INTERVAL`/`_BATCH`/`_STAGGER` knobs that used to size a shared pace are
-  gone. The 1h rest for browser Sites is safe on documented grounds: a
-  challenged page costs seconds of a serialized single-tab browser, free-plan
-  zones have no bot score and no published per-IP rate input, and
-  `cf_clearance` expires in 30 minutes so every cadence at or above 1h
-  re-solves anyway —
-  `docs/research/cloudflare-bot-scoring-and-poll-cadence.md`.
-  `USERSCRIPT_PATH` and `NOVEL_USERSCRIPT_PATH` (files served at
-  `/u/{token}/manga-bookmark.user.js` and `/u/{token}/novel-bookmark.user.js`,
-  defaults `/userscript/manga-bookmark.user.js` and
-  `/userscript/novel-bookmark.user.js`, both supplied by bindmount; the
-  `__API_TOKEN__` placeholder inside them is substituted with the requesting
-  Reader's credential at serve time).
-  `BROWSER_WS_URL` (CDP endpoint of the browser, which runs on a **separate
-  machine** and is reached over the tailnet — ADR-0006, `chrome/docker-compose.yml`.
-  Used by the poller for kagane, comix and novelfull page fetches and by the
-  cover pipeline for kagane's and comix's image bytes (the browser is the only
-  route that clears the challenge those two serve their covers behind); unset —
-  the default — disables browser polling and leaves kagane and comix Covers
-  blank until stored bytes
-  exist. Must be a tailnet IP, never a hostname: Chrome's DevTools handler 500s
-  `/json/version` for any Host that isn't an IP or `localhost`).
-- **No per-Site cover path (issue #63):** every Cover — all six Sites — is
-  served by the one public `GET /covers/{addr}` route from content-addressed
-  bytes. There is no proxy, no per-Site rewrite, no second place that decides
-  a Cover's renderable address: the wire `cover` is it. The only place a Site
-  name still appears in cover code is the extraction module (`latest`), where
-  kagane's and comix's image URLs are claimed by `browserOnlyCoverURL` — kagane
-  answers a plain fetch with a challenge and
+Each entry names the code that holds the truth — read that for *what it does*.
+The prose here is only what code cannot tell you: rationale, rejected
+alternatives, dated measurements, and invariants a plausible refactor would
+silently break.
+
+### Layout
+
+`backend/main.go` → `newRouter` is the composition root, the only place
+packages are wired. Packages under `backend/internal/`: `store`, `latest`,
+`session`, `httpmw`, `api`, `userscript`, `web`, `token`, `pgtest`. Root-level
+`*_test.go` exercise the full router; unit tests live beside their package.
+
+Not visible from any single file: stdlib `net/http` with no framework,
+Postgres over `jackc/pgx/v5`, `CGO_ENABLED=0` static binary into a distroless
+image, TLS terminated by the reverse proxy so the service listens plain `:8080`.
+
+### Schema — `internal/store/migrations/*.sql`, run by `store.migrate`
+
+- Migration files are **append-only**. Editing an applied one changes nothing
+  on a database that already recorded its version in `schema_migrations`, so
+  the fix silently applies to new deployments only.
+- No column probing, no data-fixup migrations. Both were SQLite-era machinery
+  and were removed deliberately — don't reintroduce either.
+
+### Tests need Docker — `internal/pgtest`
+
+`pgtest.Main` from `TestMain` starts one `postgres:17-alpine` per test binary;
+`pgtest.URL` hands each test its own database. A package whose tests touch the
+store must have that `TestMain` or it has no database at all.
+
+### Reader-owned store — `internal/store`, `internal/token`
+- The Reader-owned tables are `readers`, `bookmarks`, `series`, and `sessions`; auxiliary `covers`, `poll_lanes`, and `poll_passes` are also defined in the migrations.
+
+- **Credentials are derived, never stored.** `token.Token(TOKEN_KEY, discord_id, epoch)`
+  is an HMAC; only its SHA-256 reaches `readers.token_sha256`. So install URLs
+  can be rebuilt after any restart, and a database leak yields nothing usable.
+- **The owner's epoch-0 hash is refreshed at startup only while the row has
+  never been rotated.** Drop that condition and a restart resurrects a
+  rotated-away credential.
+- `Store.EnsureReader` never rewrites an existing row's hash — a returning
+  Reader's login must not invalidate their installed scripts.
+- **Every read and write is scoped to the acting Reader**, resolved from the
+  presented credential by `httpmw.Auth` and carried in the request context.
+  There is no unauthenticated-by-Reader route and no global token.
+- **`series` holds what readers share, `bookmarks` only what differs.** A
+  bookmark key is `(reader_id, site, series_id)` with no surrogate id; the wire
+  `key` is derived as `site:series_id` on read.
+- `Store.Upsert` splits one flat body across both tables and enforces the
+  ownership rule: client `title`/`series_url`/`cover` are written **only when
+  the series row is new**, so one reader cannot retitle a shared series.
+- Sync is last-write-wins and the wire format stays flat — clients depend on
+  both; neither is an implementation detail to tidy up.
+
+### Web UI — `internal/web`
+
+Routes, templates and assets are all in that package; `AdminPatterns()` and
+`adminRoutes()` enumerate the privileged ones.
+
+- **`backend/Dockerfile` must copy the whole `internal/` tree**, not just
+  `*.go`: templates and static assets are `go:embed`-ed from
+  `internal/web/`.
+- **Guild membership *is* registration.** `discordCallback` gates on membership
+  (plus `DISCORD_REQUIRED_ROLE` when set) and only then calls
+  `Store.EnsureReader`, so a refusal creates nothing.
+- Sessions are rows, not signatures: the cookie carries an opaque id and
+  expiry is checked on lookup, which is what makes deleting the row an instant
+  revocation.
+- UI mutations go through `Store.Get` + `Store.Upsert` so the `updated_at` rule
+  below stays in exactly one place.
+- `listView.Fresh` exists because a Reader with no bookmarks at all needs
+  install links, not an empty-filter message.
+- **Design-tool caveat:** `detect.mjs backend/internal/web/templates` reports a
+  **false clean**. Templates link `/static/style.css` root-absolutely (correct —
+  it is served from `/`), but the detector resolves hrefs with
+  `path.resolve(fileDir, href)`, which drops the directory on a leading `/` and
+  skips the file silently; a relative href doesn't help either, since a
+  template's directory isn't its served path. Always pass
+  `backend/internal/web/static` too. The one finding there, `overused-font` on
+  "Instrument Serif", is a deliberate identity choice, not debt.
+
+### Confirm gating — `internal/web/static/filter.js`, `toggleConfirmRow(key, kind)`
+
+Every action that pulls a series out of the list (`archive|finish|remove`) opens
+its own `.confirm-row`; restore fires instantly because it is the reversal.
+Remove wears the ember wash, the two reversible ones wear `.calm` grey.
+**`--ember` is reserved for the new-chapter signal** — the busy bar and inline
+errors must use `--mute`, or the one colour that means "something to read"
+stops meaning it.
+
+### Latest-chapter poller — `internal/latest`, Site registry in `sites.go`
+
+One goroutine per Site (a Poll Lane) re-checks that Site's bookmarked series
+from the backend's own network position, so `latest_chapter` stays fresh while
+nobody is browsing. The userscript's `reportLatestChapter` is a second,
+parallel signal — it PUTs every read, unchanged numbers included, because an
+unchanged read is exactly the Sighting worth deferring a Poll on.
+
+- **Pace lives in the Site registry, not config.** Two clocks: per-series rest
+  (`series.latest_checked_at`, enforced in `Store.DueForLatestCheck`'s WHERE)
+  and per-Lane gap (`effectiveGap`). The five env knobs that used to size one
+  shared pace are gone; don't add them back.
+- **The poller walks Series, not Bookmarks** — a series several readers hold is
+  fetched once per cycle, and the due queue orders `reader_count DESC,
+  latest_checked_at ASC` so the widely-read ones win contention.
+- **The series row is stamped *before* the fetch**, so a permanently broken
+  series waits out its rest instead of being retried every tick.
+- `Store.SetLatestChapter` is a single-column UPDATE, deliberately not a
+  read-modify-write of the bookmark: it therefore cannot revert read progress
+  or move `updated_at`. The old stale-re-read race died with the Get+Upsert
+  flow — don't restore one here.
+
+**Sightings** (`Store.RecordSighting`, the due query's HAVING clause,
+`latest.checkOne`) let a Reader's own page read defer a Poll.
+
+- Recorded by the PUT handler **before** the Upsert, because the raise test
+  needs the row as it stands.
+- A Series is deferred only while it has exactly one Bookmark, was sighted
+  within one Rest, and is under `sightingCeilingRests` since its last Poll — so
+  a shared Series is never deferred and nothing goes six hours unpolled
+  whatever arrives.
+- A *higher* report clears the attribution rather than crediting it: the value
+  the Poll then stores is its own, so a later retraction isn't the Reader's
+  fault.
+- `store.SightingDisagreementLimit` contradictions stop a Reader deferring —
+  their reports still write the Latest Chapter — and
+  `store.SightingAgreementsToClear` agreements forgive them, as does the
+  owner's clear-marks control.
+- Deferral is recomputed from live facts each round, so nothing needs
+  invalidating when a Series gains a second Bookmark. The one input read
+  earlier is the Reader's marks, so crossing or clearing a threshold takes
+  effect from their next Sighting and the standing already bought lasts out its
+  rest.
+
+**Refusals and browser loss are Lane-local.** Two `errChallengeHeld` in a pass
+stop that Site for `RefuseBackoff` while other Lanes continue. An
+`errBrowserInterrupted` (remote Chrome restarted) sets a shared Poller flag so
+the *other* browser Lanes skip their passes for the same window — otherwise a
+restarting Chrome stamps one Series per Lane per pass, burning rests on
+failures. The flag decays and they probe again.
+
+- **`isInterstitial` matches the orchestration path
+  `/cdn-cgi/challenge-platform/h/`, never the bare prefix.** Cloudflare injects
+  `/cdn-cgi/challenge-platform/scripts/jsd/main.js` into ordinary 200 pages
+  once a zone turns JS detections on, which demonic did on 2026-08-16: the
+  prefix match read every real demonic page as a refusal and parked the Lane in
+  backoff while plain TLS was returning full series pages.
+- Fetches use `bogdanfinn/tls-client` with a Chrome profile as defence in depth
+  against fingerprint blocking; any failure logs and skips.
+- kagane, comix and novelfull sit behind Cloudflare JS challenges the TLS
+  client can't clear, so they go over CDP (`BROWSER_WS_URL`). kagane and comix
+  are simply not polled when it's unset — a plain fetch would only retrieve a
+  challenge page — while novelfull still attempts plain TLS, because its
+  challenge is a live time-varying fact and its cover bytes never need a browser.
+- **comix's browser read is an in-tab `fetch()` of the Series URL, not a DOM
+  render.** It is an SPA: rendering cost ~65 requests for the same
+  server-rendered HTML one fetch returns (measured 2026-08-12).
+- Browser Lanes wake Chrome only when 5+ Series are due or one has waited 15m,
+  and cover work runs in the background so a slow CDN can't eat a Lane's gap.
+
+### Owner notices — `internal/notify`, `latest.Fault`, `latest.Notifier`, `latest.FaultsFrom`
+
+The poller's outbound owner-notice path (issue #171): one condition today
+(the stall), judged from the durable pass log alone so the poller and any
+future reader of the same judgement cannot disagree. The webhook address is a
+secret in the class of TOKEN_KEY — never logged, never rendered, never
+carried in an error. The `owner_notices` suppression table (one row per
+condition + site) is the only state; every threshold is derived, not stored.
+
+### Covers — `Store.OnSeriesCreated`, `latest.Acquirer`, `latest.CoverBytesFetcher`, `Store.SetSeriesCover`
+
+Acquired once when the first Bookmark of a Series is created, then served from
+our own origin by the public `GET /covers/{addr}`.
+
+- Acquisition runs in a goroutine: the Reader's PUT must neither block on a
+  Site nor fail with one. Every failure is logged and dropped, leaving the
+  Bookmark intact.
+- The wire `cover` is the absolute `PUBLIC_BASE_URL + /covers/{sha256}` once
+  bytes exist and `""` before — **never an address that 404s**. Absolute
+  because the userscript renders it on a Site's origin.
+- `GET /covers/{addr}` is public and uncredentialed by design: no cookie or
+  token of ours may travel to a Site's origin.
+- A client-sent `cover` is decoded and discarded, permanently — wire
+  compatibility, not an oversight.
+- **One route serves all six Sites.** No proxy, no per-Site rewrite, no second
+  place that decides a renderable address: the wire `cover` is it. Templates
+  render `.Cover` and nothing else. The old kagane-only serving path
+  (`/img/kagane/{id}` plus a template rewrite) is gone; don't reintroduce a
+  per-Site route because one Site's CDN misbehaves.
+- The only Site names left in cover code are in `browserOnlyCoverURL`
+  (`internal/latest`): kagane answers a plain fetch with a challenge *and*
   `cross-origin-resource-policy: same-origin`, and `static.comix.to` answers
-  one with the same Cloudflare challenge its pages serve;
-  every other Site's CDN answers plain TLS. Templates render `.Cover` — the
-  wire value — never anything else.
-- **Web UI also owns:** session-gated `GET /install/{manga,novel}-bookmark.user.js`
-  (renders the bindmounted script with the acting Reader's derived credential
-  substituted in — the credential never appears in page markup, the address
-  bar, or a redirect; `?download=1` adds `Content-Disposition: attachment` for
-  mobile Violentmonkey, which ignores a `.user.js` navigation) and
-  `POST /rotate-token` (atomic epoch bump + hash
-  rewrite; invalidates every installed copy, so the panel warns to reinstall
-  on all devices).
-- **Owner-only admin page (`internal/web/admin.go`, issue #102):** `GET /admin`
-  carries the Reader roster (sessions, Sighting counters, `POST
-  /readers/{id}/revoke` and `POST /readers/{id}/clear-marks`) and Poll Lane
-  status (`GET /ui/admin/lanes`, self-refreshing every 30s). Every route that
-  reaches past the acting Reader is listed in `adminRoutes()` and wrapped in
-  `requireOwner` at registration — add a route there, not a check inside a
-  handler; `web.AdminPatterns()` is what the gate test walks. A non-owner gets
-  404, never 403. Lane figures come from the running poller through the
-  `web.LaneReporter` seam (`latest.Poller.LaneStatus`), never from a table: a
-  nil reporter or a Lane that has not finished a pass renders "no data yet"
-  rather than zeroes. `main.newRouter` takes the reporter as an interface and
-  converts a nil `*Poller` to a nil interface — a typed nil would make the page
-  claim a poller exists.
-  The one owner comparison left outside `requireOwner` is in `index`
+  with the same challenge its pages serve. Every other Site's CDN answers plain
+  TLS.
+- **comix cover bytes must arrive by direct navigation, not an in-page fetch:**
+  its Series page sets `cross-origin-embedder-policy: require-corp`, which
+  fails a page-context fetch of `static.comix.to`.
+- With no browser configured, kagane and comix Covers are simply absent;
+  novelfull still gets one whenever its page answers a plain request.
+
+### `updated_at` drives list order — `Store.Upsert`
+
+The server applies its own timestamp only when the row is new or
+`last_chapter_num` changes, else it keeps the stored value. **Favouriting a
+series, or a newly published chapter arriving, must not reorder the list** —
+only real reading progress moves a row. Consequently `PUT` returns the row **as
+stored** and clients must adopt that response rather than their own payload.
+
+### Lifecycle buckets — `status` on each bookmark
+
+`reading` | `archived`, orthogonal to `favorite`. Archived rows appear only
+in their own tab, never in All, Updated, Favourites or the recent strip. The
+poller keeps checking archived series; a finished Series (issue #157) is a
+`series.finished_at` fact the Lane gate reads, with every bookmark on it
+archived.
+
+- `PUT /bookmarks/{key}` accepts only the two values; anything else —
+  `finished` included — is a plain 400, and the web UI's own status control
+  validates the same way. The 0016 migration is the only writer of the flag
+  today; the undo is writing 0.
+- **An empty incoming status means "keep the stored one"**, and it is resolved
+  on the `VALUES` side of `Store.Upsert`, not in the conflict clause:
+  `excluded.*` is the post-evaluation row, so a default applied there would
+  wipe the bucket on every PUT from a client predating the column.
+
+### Config — `Config` / `loadConfig` / `loadLatestPoll` in `backend/main.go`
+
+That function is the complete list of env vars, their defaults, and which are
+required. What it can't tell you:
+
+- `PUBLIC_BASE_URL` must be an absolute origin because every Cover URL on the
+  wire is built from it and the userscript renders on a Site's origin.
+- `BROWSER_WS_URL` **must be a tailnet IP, never a hostname** — Chrome's
+  DevTools handler 500s `/json/version` for any Host that isn't an IP or
+  `localhost`. Unset (the default) disables browser polling.
+- `USERSCRIPT_PATH` / `NOVEL_USERSCRIPT_PATH` are bindmounted files; the
+  `__API_TOKEN__` placeholder inside them is substituted with the requesting
+  Reader's credential at serve time.
+- Pace is per Site in the registry, not env. The
+  `_COOLDOWN`/`_BROWSER_COOLDOWN`/`_INTERVAL`/`_BATCH`/`_STAGGER` knobs are
+  gone on purpose.
+- The 1h rest for browser Sites is safe on documented grounds: a challenged
+  page costs seconds of a serialized single-tab browser, free-plan zones carry
+  no bot score and no published per-IP rate input, and `cf_clearance` expires
+  in 30 minutes, so every cadence at or above 1h re-solves anyway.
+
+### Userscript install & rotation — `internal/userscript`, `internal/token`
+
+Session-gated `GET /install/{manga,novel}-bookmark.user.js` renders the
+bindmounted script with the acting Reader's derived credential substituted in,
+so the credential never appears in page markup, the address bar, or a redirect.
+`?download=1` adds `Content-Disposition: attachment` for mobile Violentmonkey,
+which ignores a `.user.js` navigation. `POST /rotate-token` is an atomic epoch
+bump plus hash rewrite and invalidates every installed copy — the panel must
+keep warning to reinstall on all devices.
+
+### Owner-only admin — `internal/web/admin.go`
+
+- **Every route reaching past the acting Reader is listed in `adminRoutes()`
+  and wrapped in `requireOwner` at registration** — add it there, not as a
+  check inside a handler; `web.AdminPatterns()` is what the gate test walks. A
+  non-owner gets 404, never 403.
+- The one owner comparison left outside the gate is in `index`
   (`view.Owner = readerID == h.store.OwnerID()`): it gates a link, not an
   endpoint, so it is a rendering decision a registration-time wrapper cannot
-  express — do not "unify" it into the gate.
-  A Lane pass that returns before computing its figures (refusal backoff,
-  sidecar down) carries the previous pass's due count and gap forward rather
-  than recording zeroes; a Lane that has never reached a pace renders no gap at
-  all. `Checked` next to `Due` is what separates a stopped Lane from a quiet
-  one, so neither figure may be dropped from the row.
-  Due-without-Checked is *not* by itself a stall: a browser Lane under both
-  wake thresholds sets `LaneState.Asleep` at the on-demand gate and renders
-  "browser asleep" instead of "not checking", and never counts toward
-  `Attention`. That is the commonest healthy state for kagane, comix and
-  novelfull — one due Series, nothing checked — so spending the stall mark on
-  it would train the owner to ignore the mark that matters.
+  express. Do not "unify" it into the gate.
+- The Lanes page reads the pass log, never a running poller: `lanesView()` in
+  `admin_lanes.go` projects `store.LatestLanePasses()` and
+  `store.LanePassOutcomes()` (ADR-0012), so a restart answers the instant the
+  database is up. Browser configuration is a config fact and reachability is
+  derived from recent browser-Site passes inside `latest.RefuseBackoff` — no
+  reporter interface exists to fake.
+- A pass that returns before computing figures (refusal backoff, sidecar down)
+  carries the previous pass's numbers forward rather than recording zeroes.
+- **`Checked` next to `Due` is what separates a stopped Lane from a quiet one**,
+  so neither may be dropped from the row.
+- Due-without-Checked is **not** by itself a stall: a browser Lane under both
+  wake thresholds records its pass with the `SkipAsleep` skip and renders
+  "browser asleep", and that never counts toward `Attention`. It is the
+  commonest healthy state for kagane, comix and novelfull, so spending the
+  stall mark on it would train the owner to ignore the mark that matters.

+//
+// The WHERE set is: no URL (an empty URL only — the host-failing-the-fetch-
+// gate case is invisible to SQL, needs the Site registry in Go, and belongs to
+// a later repair), never-read-a-chapter and never-checked as disjoint halves
+// (non-zero versus zero check stamp), stale, no cover, finished (the
+// retirement stamp, read directly), site completed (the Site's marker, read
+// directly), Reader-report, and the failing pair — failing (the failure row
+// exists, a chapter exists, and failing_since is past the cutoff) and
+// unverified (the Reader-attributed subset of failing).
+// failing's chapter IS NOT NULL is the exact complement of never-read-a-
+// chapter's IS NULL half, so the two are disjoint by construction.
+// no_readers is the one HAVING predicate: it is the orphan test, an aggregate
+// over the LEFT JOIN, where a bare WHERE has no row to test.

+// The clock-versus-outcome split decides which predicates exclude finished
+// Series (`s.finished_at = 0` in each of the five): the clock-driven ones —
+// never-checked, stale, no-chapter, no-cover — keep ticking after the last
+// Poll, so they would report a retired row as a problem no Poll is coming to
+// fix; site-completed's stamp is the Site's, and it keeps standing after the
+// owner retires the row, so a finished Series would be reported as work
+// nobody is going to do. The outcome-driven ones — no-URL, no-readers,
+// Reader-report, failing, unverified — read stored facts that simply stop
+// arriving, so a finished Series needing a genuine repair still shows up
+// under them. The failing pair carries no finished guard for exactly that
+// contrast: a failure row is a stored outcome, not a ticking clock.
+//
+// stale is the checked-but-old half of the stamp partition — because the
+// verdict line wants "not checked in twelve hours" as one figure, and a never
+// checked Series is already counted on its own "waiting"/never-checked
+// filter, folding it in would double-report it. The landing page computes the
+// inclusive number as stale + never-checked.

+# ADR-0012: Persisted lane state
+
+Date: 2026-08-21
+Status: accepted
+
+Supersedes the in-memory lane snapshot carried by `latest`'s `LaneState`/`Status`
+and the `web.LaneReporter` seam (ADR-0010 wrote the durable rows this page now
+reads).
+
+## Decision
+
+The admin Lanes page stops reading the poller's in-memory Lane state and
+becomes a read of `poll_passes`/`poll_lanes` in Postgres. There is no
+`LaneReporter` interface: `web/admin_lanes.go` walks `store.LatestLanePasses()`
+into one row per Site and adds the window's outcome sums from
+`store.LanePassOutcomes()`. The `latest` package's `LaneState`/`Status` snapshot
+and its `web.LaneReporter` seam are deleted.
+
+The browser is a deployment configuration fact plus a reachability derived
+from the pass log: `BROWSER_WS_URL` set means "configured", and the browser is
+"reachable" unless a recent browser-Site pass inside `latest.RefuseBackoff` is
+a sidecar loss, a missing fetcher, or an interrupted read. A skip reason is
+the whole difference between a Lane resting and a Lane stuck: a skipped pass
+prints its sentence, and only an empty skip with Series due and none read
+draws the true-stall fault. Sleep skips never count toward `Attention`.
+
+## Why
+
+The old page lived on a poller snapshot. Because that state was in memory, a
+deploy erased it: the page read zeroes until a fresh pass ran, and browser
+reachability came through a reporter interface only a live poller could
+serve. Making the page answer from the database means a restart is complete
+the instant the store is up, the browser fact survives a poller restart, and
+a Lane that has not yet gathered figures shows a placeholder rather than a
+confident zero.
+
+## Constraints
+
+The poller still owns the writes: each pass exit records one row (ADR-0010),
+and a pass that returns before gathering figures carries the previous pass's
+numbers forward instead of recording zeroes. A skip is a stable wire string;
+`asleep` never counts toward `Attention`. When polling is switched off
+(`LATEST_CHAPTER_POLL_ENABLED` unset) the page must say so, and the browser
+statusline appears only when polling is switched on.

+# ADR-0013: Commands through the database
+
+Date: 2026-08-22
+Status: accepted
+
+## Decision
+
+Owner interventions are **facts about rows, never commands to the poller**.
+*Check now* (`POST /admin/series/{key}/poll`) writes one stamp —
+`series.force_poll_at`, unix ms, zero meaning never asked (the column landed
+in migration 0014) — and the poller's next pass reads it through
+`Store.DueForLatestCheck`. The control never signals the running process, so
+a request survives a restart, and the whole surface is testable with no
+poller running at all.
+
+**Pending is derived, never stored**: a Series is pending while
+`force_poll_at > latest_checked_at`. It self-clears with no second write and
+no sweeper because the check stamp is written *before* the fetch (the same
+"attempted" discipline as ADR-0010) — the first attempt ends the pending
+state whatever the attempt returns. There is no expiry: a request the Lane
+never reaches keeps ageing in the UI, and an old pending marker is itself the
+evidence that a Lane is stuck. Writing again re-stamps the request time; the
+write is idempotent.
+
+**Queue-jump rules.** A forced Series overrides exactly three gates in the
+due query: the rest cutoff, the Sighting-deferral clause and the finished-only
+bucket, and it sorts to the front of the queue
+(`ORDER BY forced DESC, reader_count DESC, latest_checked_at ASC`). It never
+overrides an empty `series_url` (nothing to fetch), the Bookmarks join (a
+Series no Reader holds has no consumer for the result), the Lane's refusal
+backoff, the sidecar-down skip, or the Lane's gap — the last three are
+poller-side gates the query cannot see and must not. The one pass-level gate
+a forced Series does open is the browser wake threshold: a human asking wakes
+a sleeping Chrome, where the thresholds exist to stop the machine waking
+itself for one unattended check. If the home machine is off, nothing happens
+and the request ages visibly, which is correct.
+
+Rejected: zeroing the check stamp as the force signal. It would corrupt the
+never-checked and stale counts the landing page exists to show, and make a
+pending marker impossible.
+
+## Why
+
+A stuck-looking Series previously waited for its turn in the Lane's hour, and
+there was no way to ask for one check sooner. A direct poller command would
+have been lost on every restart and untestable without a running poller; a
+row the poller already reads is neither. Deriving pending from the two stamps
+keeps the flag honest across restarts and makes the mechanism two column
+writes and three query clauses instead of a state machine.
+
+## Constraints
+
+- The finished-status clause the force flag overrides is today's Lifecycle
+  test; a later spec in this series deletes it wholesale rather than amending
+  it, so the clause stays as it stands.
+- The control is unconfirmed (it takes nothing away) and renders no
+  `.confirm-row`; it is hidden on a Series with no `series_url` and on an
+  orphan — the same pair the due query refuses to override.
+- The answer to a press is the freshly rendered row, so the figures describe
+  the state after the press.

+# ADR-0014: Cover addresses derived from the bytes, not the source URL
+
+Date: 2026-08-22
+Status: accepted
+
+## Decision
+
+A Cover's content address is the hex SHA-256 of its **bytes**, not of the
+source URL it was fetched from. `CoverAddressForBytes(body)` names the address
+`putCover` stores under, `SetSeriesCover` and `ReplaceSeriesCover` point the
+Series row at it, and the wire URL is built from it exactly as before — same
+route, same 64-hex-digit shape, same immutability, only the input to the hash
+changes. Rows written before this ADR keep their URL-derived addresses
+forever: they are never rehashed on read, and they heal into byte addressing
+only when a Forced Poll replaces them.
+
+`ReplaceSeriesCover(site, seriesID, sourceURL, body, contentType)`
+`(previous, current, error)` is the one write that may move a Cover once one
+exists. It stores the bytes, then in one transaction locks the Series row,
+reads the old `cover_address`, writes the new one and the source URL, and
+reports both addresses: `previous == ""` means there was no Cover,
+`previous == current` means the Site served identical artwork, and any other
+pair names the stranded address.
+
+## Why a future reader will find this surprising
+
+The address is what makes a re-art visible at all. URL addressing collapses
+every image behind a stable URL into one address, so a Series whose Cover
+changes (a big-budget CPI blitz on a light novel is the standing example)
+keeps serving its original cover bytes: the poll refetches the same URL,
+hashes it, and the store records the same address, everyone happy except the
+Reader. Nothing in the system can detect the change, because the address is a
+pure function of the fetch target, and identical bytes written 1,000 times
+are one blob on disk. Storing bytes we already know how to store is only a
+few lines of work. **Rejecting that work is the surprising part, and the
+answer is the Forced Poll wave**: for a corrupt/blank cover the poll's
+fill-if-blank installer already worked, but for a *wrong but non-blank* cover
+there was no write that would move it at all — only a manual truth in
+`series.cover_address`, which is exactly the thing that must never be set by
+hand. Byte addressing gives the replacement write a **new address to write**,
+and with it a legitimate, transaction-safe mover.
+
+## Considered options
+
+**Keep URL addressing and add a generic "clear the cover" write.**
+Rejected: clearing is a two-phase action (blank it, wait for the poll to
+re-fill, hope the bytes changed in between) that cannot report what the
+write did, and it makes the Series render cover-less in between. The
+replacement write is atomic, reports its displacement, and has one effect:
+the Series now points at bytes that actually came from its source URL.
+
+**Address by URL, but salt it so a re-art is a new address.**
+Rejected: the salt would have to live somewhere addressable (a stored per-
+Series nonce), turning the address from a content fact into a mutable fact —
+two rows could then hold identical bytes under different addresses and the
+invariant "same bytes object" is gone.
+
+## Consequences

+- `store.CoverAddress` (URL-hash) is deleted; `CoverAddressForBytes` is
+  public so tests and the forced-poll wave can predict addresses from the
+  bytes fakes serve.
+- Legacy URL-addressed rows are read-only facts: `GetCover(sourceURL)` keeps
+  resolving them (the poll heal path), and they are re-addressed only by a
+  forced replacement. Until one happens, they are invisible to byte-derived
+  lookups — the reverse direction was always true, so this side has no
+  migration and no lookup fan-out.
+- A replaced Cover's old bytes stay on disk under their address (the `covers`
+  row is untouched — only the Series row moves). Nothing reclaims them
+  today; a later sweep is a small query over `covers` addresses not
+  referenced by any `series` row.
+- `SetSeriesCover` keeps its `cover_address = ''` guard untouched: the
+  acquisition-at-creation and poll fill paths still may not overwrite a
+  non-blank Cover. The two installers are now deliberately different
+  functions instead of one function with a conditional.
+- The address is still a filesystem path (≤64 hex chars, no separators), so
+  `coverAddressRe` and the sharding stay exactly as they are.
+
+## Cost of reversing
+
+The URL-hash side of the current rows is uncomputable from the rows alone: a
+rollback would need every stored blob's source URL, a join to a table that
+does not store it, or a refetch of every Series. Keeping both derivations
+resolvable is cheaper than either, so the two derivations are documented in
+the 0009 migration comment: no component may assume which derivation a
+stored address came from, because the 64-hex shape hides it.

+# ADR-0015: Finished is a fact about the Series, not a bookmark bucket
+
+Date: 2026-08-22
+Status: accepted
+
+## Decision
+
+"Finished" moves from the per-Reader `bookmarks.status` bucket to a
+Series-owned flag: `series.finished_at`, unix ms, zero while the Series is
+still running. The Lane's gate reads the flag — a Series is polled only while
+`finished_at = 0` — and `bookmarks.status` keeps exactly two values,
+`reading` and `archived`.
+
+The cutover is one-way, done by migration 0016 in three load-bearing
+statements:
+
+1. `ALTER TABLE series ADD COLUMN finished_at bigint NOT NULL DEFAULT 0`.
+2. Seed it from the bookmarks: a Series is stamped finished when no bookmark
+   on it is outside the `finished` bucket. This mirrors the pre-cutover due
+   gate exactly — the old query skipped a Series only while
+   `COUNT(*) FILTER (WHERE status <> 'finished') = 0` — so no Series changes
+   polling state at the cutover.
+3. Rewrite every `finished` bookmark to `archived`. The bucket is gone; the
+   seed ran first because it is the only statement that can still read it.
+
+The JSON API rejects a `finished` status with the same plain 400 as any
+unknown value, and the web UI no longer offers a Finished tab, a finish
+button, or a finished state badge.
+
+## Why a future reader will find this surprising
+
+The bucket looked Reader-shaped but described a Series fact. A Series is
+finished once, and every Reader reading it is then on a finished Series —
+yet the bucket carried three copies of the answer, one per Reader, free to
+disagree. The disagreement is not theoretical: a second Reader who merely
+kept the Series (or never read it) kept it in `reading`, so the poll gate
+kept fetching a Series the first Reader had closed out, forever. Worse, the
+disagreement was never resolvable — nothing in the system could say "this
+Series is finished" without rewriting every bookmark, which silently edits
+another Reader's progress state.
+
+The flag is also the only memory of the bucket after the flip. `finished`
+bookmarks become `archived` because a two-value status needs no third
+value, and an archived row must keep meaning "shelved, but the Series is
+being watched" — which is what the row says. The migration's seed is what
+keeps the legacy meaning: a Series every Reader finished is stamped, so the
+Lane stops polling it just as it would have pre-cutover; a Series any
+Reader still reads is left alone, exactly as the old gate left it. A
+Series whose every Reader only shelved (archived) continues to be polled,
+because an archived bookmark is *supposed* to be polled — the cutover
+changes the answer, it does not invent it. And because the flag is a series
+fact, the cutover also repairs the disagreement case: the moment one Reader
+has the Series open, it reads as finished to everyone.
+
+The migration is the only writer of the flag today; the undo is writing 0,
+which returns the Series to the poll. An owner-facing "mark finished" write
+is deliberately not part of this change — the gate is what this ticket
+rewrites, and the write can land on top of it without touching anything
+here.
+
+The userscript merge ranks `archived > reading` now. `finished` is not a
+value the wire can carry, so the merge cannot un-finish a row — it cannot
+even name the state it is protecting.
+
+## Considered options
+
+**Keep the bucket and add the flag alongside it, both live.**
+Rejected: two sources of truth for one fact, with the Lane forced to
+resolve "any Reader finished?" on every due query and every Reader write
+still able to resurrect a finished Series. The whole point of the change is
+that the finished state survives Readers.
+
+**Stamp a Series finished when every bookmark is finished *or* archived.**
+Rejected: it flips polling state at the cutover. Shelved-only Series were
+polled before; making them finished stops the checks the reader knowingly
+asked to keep.
+
+**Finish as "no bookmark is reading", leaving the buckets untouched.**
+Rejected for the same reason plus one: `archived` is a Reader's own state
+and the flip is what makes the flag the *only* source of finished. Keeping
+the `finished` value in the table would force every status validation,
+merge and UI branch to keep handling a value no write can produce.
+
+## Consequences
+
+- `bookmarks.status` is validated to `reading | archived`, empty meaning
+  "keep the stored value"; the API's 400 for `finished` is now the generic
+  invalid-status rejection rather than a special case, and the web UI's own
+  status control rejects it the same way.
+- The Lane due query and the eligible count read `finished_at`; a Forced
+  Poll (issue #146) still overrides the flag — the owner asked, so the Lane
+  looks — and the pending force clears itself when the pass stamps the
+  check timestamp, never by touching `finished_at`.
+- The web UI has no Finished tab; finished Series render in Archived with
+  their archived badge, dimmed like any shelved row.
+- Migration 0016 stamps `finished_at` with the migration's own clock
+  (`now()` ms), which is also the undo: write 0 and the Series returns to
+  the poll.
+
+## Cost of reversing
+
+The finished buckets are destroyed by the flip; reversing means re-deriving
+per-Reader finished state from a Series fact that now encodes the
+majority-agreement snapshot plus whatever the owner reset since. The stamp
+differentiates "finished at the cutover and untouched" from "finished
+later", but not which Reader's choice each Series carried, and any Series
+the owner has since restored is gone from the derivation entirely. The ADR
+is a statement of intent to ship the one-way cutover and live with its
+consequences; the per-Reader history is not kept anywhere in the schema.

+# ADR-0016: The failure row is the state
+
+Date: 2026-08-22
+Status: accepted
+
+## Decision
+
+A Series that used to work and has stopped is recorded in one table,
+`poll_failures`, keyed by the same `(site, series_id)` composite the rest of
+the system uses. One row per failing Series, carrying the outcome word and a
+`failing_since` stamp. The row's **existence** is the failure state: there is
+no success sentinel, no counter, no history, and nothing added to the Series
+row. A correct read deletes the row, and a repeated identical failure writes
+nothing — the stamp ages the run of failures, not the current word.
+
+The write is one upsert, from the poll pass loop:
+
+```sql
+INSERT INTO poll_failures (site, series_id, outcome, failing_since)
+VALUES ($1, $2, $3, $4)
+ON CONFLICT (site, series_id) DO UPDATE SET outcome = EXCLUDED.outcome
+WHERE poll_failures.outcome <> EXCLUDED.outcome
+```
+
+`failing_since` is simply absent from the `SET` arm, so it is never
+overwritten, and the `WHERE` makes an unchanged word write nothing at all —
+one statement, no read-then-write race. The clear is a plain `DELETE`; a row
+that is not there is not an error, because the poller clears on every
+successful read and most clears find nothing. The composite foreign key
+cascades: deleting a Series takes its failure row, so orphan removal stays a
+single statement.
+
+## Why a future reader will find this surprising
+
+The failure state lives in a table of its own, not on the Series row and not
+in the pass log. A flag on `series` would be the familiar shape, and the
+pass log already records outcomes per pass — why a third place?
+
+Because the failure must outlive the pass that observed it and mean
+something the pass row cannot say. The pass log is a per-Lane stream: it
+records that a Site returned N `errors` and M `not_found` on a given run,
+but "this exact Series has been failing for three months" is not a question
+any single pass row answers — it is a question across rows, and the Lanes
+page is a live view of the last 14 days, not a Series index. A Series-level
+fact needs Series-level storage, and a flag on the Series row is the wrong
+shape too: the failure is *transient by definition* (a correct read ends it)
+and *repeatable* (the same Series can fail again next year), so the honest
+record of "failing since" is a stamp that moves, not a column that flips.
+A row that is created and deleted by the read's outcome is that stamp, and
+nothing else: the moment a read succeeds the row is gone, so "is this Series
+failing?" is answered by one indexed existence check — no success sentinel
+to keep consistent with the failure, no counter to reset, no history to
+prune. The state cannot drift out of step with the reads that maintain it,
+because the reads *are* the maintenance.
+
+The two no-write outcomes are the second surprise. `refused` (the Site is
+holding a challenge) and `unreachable` (the browser sidecar was lost
+mid-loop) issue **no statement at all** — neither an upsert nor a delete.
+The direction matters, and both directions are wrong to touch:
+
+- **Writing would condemn a whole library for one Site's bad day.** A
+  refusal is the Site's mood, not a fact about any particular Series: when
+  Cloudflare turns a zone's JS detection on, every Series on that Site reads
+  refused in the same pass. Writing those rows would stamp every Series in
+  the library as failing on the evidence of one Site's configuration, and
+  #166's worklist would present a Site-wide outage as thousands of broken
+  Series.
+- **Deleting would claim a recovery nothing read.** A lost sidecar tells us
+  nothing about the page — the read never happened. Deleting the row would
+  report the Series healthy, and worse, it would reset `failing_since`: the
+  age that makes a three-month failure findable would start over on a
+  browser restart, erasing evidence no page read contradicted.
+
+So a refusal or an unreachable pass leaves the table exactly as it found
+it — the pass neither adds rows that would condemn nor deletes rows that
+would claim recovery. The four outcomes that are real evidence about the
+page (`not_found`, `no_chapter`, `unfetchable`, `errors`) write; the two
+that are not write nothing; success deletes. There is no third case.
+
+## Considered options
+
+**A `failing_since` column on the Series row, alongside the failure word.**
+Rejected: it is two more columns on a table every due query and every
+bookmark join already touches, for a state that is transient and repeatable.
+The column would need its own "clear on success" writer anyway — the same
+maintenance the row has — while permanently widening the hottest table in
+the system for a value that is usually absent. And the worklist's join
+would have to distinguish "never failed" from "currently healthy", which
+is exactly the sentinel problem the row avoids: an empty column means both.
+
+**A counter or last-outcome timestamp instead of (or beside) the row.**
+Rejected: nothing in the system consumes a failure *count* or a
+last-outcome time — the worklist needs "failing and since when". A counter
+invites "three failures = something" thresholds that the ticket explicitly
+keeps out of scope, and a last-outcome timestamp conflates "the word
+changed" with "the run restarted", which the age is deliberately defined
+against. The stamp is the only number that means anything, and the row
+carries exactly that.
+
+**Write into `poll_passes` and derive the failure state from the pass
+stream.**
+Rejected: a pass row is per-Lane and per-run; deriving "this Series is
+failing since" means scanning 14 days of outcome counts per Series and
+guessing at continuity across retention boundaries. The pass log answers
+"what did this Site's lane do recently"; the failure table answers "which
+Series are broken right now". Two questions, two tables — the pass log is
+already pruned on a fixed cutoff, which would silently reset every
+failure's age the moment the evidence aged out.
+
+**Refused/unreachable write nothing, but the delete happens anyway (or the
+upsert happens, with no delete).**
+Rejected in both directions, above: writing condemns a library for one
+Site's mood; deleting claims a recovery nothing read and resets the age
+that makes a long failure findable. The asymmetry is the point — the two
+outcomes are evidence about the *environment*, never about a page.
+
+## Consequences
+
+- The poller writes from the pass loop, one call after `checkOne`, and
+  clears through the ordinary success path: a Forced Poll that reads the
+  page deletes the row with no forced branch of its own, and a Forced Poll
+  *request* — which only stamps the request — clears nothing.
+- `poll_failures` is a poll-write table like `poll_lanes` and
+  `poll_passes`: the store's two methods live next to the Lane-pass
+  writers, and neither runs on a request path. A store failure is logged
+  and the poll continues — a failure row is best-effort, and no single bad
+  Series may stall a Lane.
+- The due query does not join the table. A failing Series is polled at the
+  same pace as any other, because the moment the query started pacing by
+  failure state, the age would stop meaning what the worklist reads it as.
+- Orphan removal stays a single statement: the composite foreign key's
+  `ON DELETE CASCADE` is what takes the failure row with the Series.
+- The table starts empty at deploy, so nothing is findable for the first
+  twelve hours after deploy and a pre-existing breakage reads as new.
+  Accepted; the alternative is inventing history.
+
+## Cost of reversing
+
+The failure state is derived, not stored: a rollback drops the table and
+every in-progress failure age with it, leaving the pass log's outcome
+counts as the only trace — which is exactly the "log line nobody reads"
+the ticket set out to replace. Recreating the table later starts the ages
+over, so a reversal that is later reversed loses the evidence of the
+intervening failures. The failure state itself, however, is the one thing
+that is *not* lost by reversing: it is re-derived from the next pass, in
+the same direction the original design derives it — the row is
+recreated by the next failing read and deleted by the next good one.

+## 1. Summary answer table
+
+| Question | Answer | Evidence |
+|---|---|---|
+| Does the GIF89a spec define a maximum file size? | **No.** There is no file-size field anywhere in the format; the only numeric ceilings are per-field (16-bit screen/image dimensions, 255-byte sub-blocks, 12-bit LZW codes). | §2 |
+| Maximum logical screen | 65535 × 65535 pixels (unsigned 16-bit width/height). | §2.1 |
+| Number of frames / image descriptors | Unbounded — "An unlimited number of images may be present per Data Stream." | §2.2 |
+| Formal max byte size of any single GIF | None. Single-frame worst case ≈ **6.44 GB** (12-bit LZW, max canvas); animated GIFs are **unbounded** because frames are unbounded. | §3 |
+| Does the backend's decoder (Go `image/gif`) bound size? | **No.** It reads 16-bit dimensions and allocates `width×height` bytes per frame; a 65535² frame forces a ~4 GiB allocation. No total-size or dimension guard. | §4.1 |
+| Do browsers bound on-disk GIF size? | Chromium and Firefox: no on-wire size cap in their GIF readers; Chromium caps *decoded* memory at min(4 B × pixels, platform budget). | §4.3, §4.4 |
+| Real cover sizes (asurascans, n=25) | min 190,410 B · median 1,275,082 B · p90 4,524,788 B · max 8,571,192 B · **3/25 > 4 MiB** (two JPEGs and the animated GIF) | §5 |
+| Real cover sizes (demonicscans/readermc, n=78) | min 13,298 B · median 63,061 B · max 801,200 B · 0/78 > 4 MiB | §5 |
+| Comparable service caps | GitHub: 10 MB for images/GIFs. Discord API: default 10 MiB per file. Wikimedia: 100 MiB upload / 5 GiB host. | §6 |
+| Recommended cover cap for #71 | **10 MiB** (separate from the 4 MiB series-page cap). Covers 100% of the 103 observed covers; matches GitHub/Discord calibration; ≤ 20 MiB worst-case transient per concurrent fetch+serve on a 1974 MiB swapless VPS. | §7 |

+
+## 2. What the GIF89a specification actually bounds
+
+Source: `https://www.w3.org/Graphics/GIF/spec-gif89a.txt` (fetched 2026-08-17).
+
+### 2.1 Fixed-width fields — the only hard ceilings
+
+The format is a stream of fixed-width blocks; the numeric fields that *do*
+have a ceiling are all 16-bit unsigned, little-endian ("multi-byte numeric
+fields are ordered Least Significant Byte first", §4 of the spec):
+
+- **Logical Screen Width / Height** — "Unsigned" 2-byte fields (§18, Logical
+  Screen Descriptor) → maximum **65535 × 65535** pixels.
+- **Image Left / Top Position, Image Width / Height** — "Unsigned" 2-byte
+  fields (§20, Image Descriptor). Each image "must fit within the boundaries
+  of the Logical Screen" (§20a), so an image cannot exceed the 65535² canvas
+  even though its own fields would allow it.
+- **Data sub-blocks** — "A data sub-block may contain from 0 to 255 data
+  bytes" (§15); each sub-block is preceded by a 1-byte size field and the
+  stream is terminated by a 0x00 Block Terminator (§16). This bounds a
+  *chunk*, not the stream.
+- **Global/Local Color Tables** — optional, "3 x 2^(Size of Global Color
+  Table+1)" bytes with a 3-bit size field → at most 3 × 2⁸ = **768 bytes**
+  each (§19, §21).
+- **LZW codes** — "The output codes are of variable length, starting at
+  <code size>+1 bits per code, **up to 12 bits per code**. This defines a
+  maximum code value of 4095 (0xFFF)" (Appendix F, COMPRESSION, rule 4).
+- **Trailer** — a single byte, fixed value 0x3B, "indicating the end of the
+  GIF Data Stream" (§27).
+
+### 2.2 What is unbounded
+
+- **Number of images (frames).** §20a, verbatim: "This block is REQUIRED for
+  an image. Exactly one Image Descriptor must be present per image in the
+  Data Stream. **An unlimited number of images may be present per Data
+  Stream.**"
+- **The Data Stream itself.** The grammar in Appendix B is
+  `<GIF Data Stream> ::= Header <Logical Screen> <Data>* Trailer`, and the
+  spec states "the entity Data … may be repeated any number of times,
+  including 0 times." There is **no field anywhere that carries a file size,
+  byte count, frame count, or total-length value**. §13 (Block Sizes) only
+  defines sizes *within* blocks.
+
+### 2.3 Verdict
+
+**The GIF89a specification defines no maximum file size.** The only hard
+bounds are per-field: 65535×65535 pixels per screen/image, 255 bytes per
+sub-block, 12 bits per LZW code, and one trailer byte. A compliant decoder
+must process whatever stream the blocks describe. Any byte ceiling a
+particular GIF actually hits is therefore *implicit* — 16-bit dimensions,
+LZW code width, decoder memory, or an external policy — never something the
+format itself enforces. `[INFERENCE]` This is why real-world GIFs cap out at
+"a few GB at most" and every service that wants a bound has to impose one
+itself (see §6; Wikimedia explicitly documents that a 4 GiB host limit was a
+storage-representation artifact of 32-bit integers, `phab:T191805`, not a
+format limit).
+
+---
+
+## 3. Theoretical worst case
+
+### 3.1 Single frame, maximal canvas, 8-bit pixels
+
+| Quantity | Value | Derivation |
+|---|---|---|
+| Max pixels | 4,294,836,225 | 65535 × 65535 |
+| Raw 8-bit palette-index raster | 4,294,836,225 B ≈ **4.29 GB / 4.00 GiB** | 1 byte per pixel (Table Based Image Data, §22; Go's `image.Paletted` uses exactly 1 byte/pixel) |
+| LZW worst case | ≈ **6.44 GB / 6.00 GiB** | codes ≤ 12 bits each (Appendix F), at most ~1 code per pixel for incompressible data → ≤ 12 bits/px = 1.5 B/px → 4,294,836,225 × 1.5 B |
+| Sub-block overhead | ≈ +25.3 MB | every ≤255-byte chunk carries a 1-byte size field (§15): ⌈6,442,254,338 / 255⌉ ≈ 25,263,743 size bytes, + 1 block terminator |
+| Fixed overhead | ≈ +1.6 KB | header 6 B (§17) + logical screen descriptor 7 B (§18) + global color table ≤ 768 B (§19) + image descriptor 10 B (§20) + local color table ≤ 768 B (§21) + LZW minimum code size 1 B (§22) |
+
+So a **single maximal-frame GIF cannot exceed ≈ 6.47 GB on the wire**
+(12-bit LZW bound), and LZW being lossless means the real byte count depends
+entirely on image content — the same canvas can be a few KB (flat color) or
+~6 GB (noise).
+
+Two caveats, both marked `[INFERENCE]`:
+
+- The "1.5 B/px" figure assumes ~one emitted code per pixel. An encoder is
+  permitted to emit a Clear code at any point (Appendix F: "The Clear code
+  can appear at any point in the image data stream"), so a
+  pathological-but-compliant encoder emitting clear+pixel per pixel reaches
+  ~24 bits/px ≈ 12.9 GB for the max canvas. Real encoders do not do this;
+  12-bit/px is the practical bound.
+- The spec's deferred-clear note (cover sheet) explicitly allows an encoder
+  to keep using a full table at 12-bit codes without clearing, so the 12-bit
+  cap holds for the whole stream, it cannot "grow" past 12 bits.
+
+### 3.2 Animated GIFs: unbounded
+
+Every frame is one Image Descriptor, each bounded by the 65535² canvas, but
+the *count* of frames is unbounded (§2.2). Total bytes = sum over frames —
+therefore **there is no finite maximum byte size for an animated GIF** in
+the format. The only thing that stops a real one is decoder memory, a
+service cap, or disk space. `[INFERENCE]` This is the category the issue #71
+cover falls into: it is an animated GIF (NETSCAPE2.0 loop extension found at
+offset 0x310 of the file, verified 2026-08-17 by a ranged GET), and its
+8,571,192 bytes are ~2.04× the current 4 MiB backend cap.
+
+---
+
+## 4. Decoder-side real limits
+
+### 4.1 Go `image/gif` (the backend's decoder path, stdlib)
+
+Source: `/usr/local/go/src/image/gif/reader.go`, Go 1.26.5.
+
+- Dimensions are read as little-endian uint16 — `left/top/width/height :=
+  int(d.tmp[N]) + int(d.tmp[N+1])<<8` (reader.go:490-493) — so the format
+  ceiling 65535 applies, and nothing smaller is enforced.
+- The only geometric check is that each frame fits inside the logical
+  screen: `if left+width > d.width || top+height > d.height` →
+  `errors.New("gif: frame bounds larger than image bounds")` (reader.go:512-513).
+- **There is no file-size, byte-count, frame-count, or pixel-count guard.**
+  Each frame allocates `image.NewPaletted(...)` (reader.go:515) — a
+  `[]byte` of width×height — so decoding one legal 65535² frame attempts a
+  **~4.29 GB allocation**. `DecodeAll` (reader.go:603-605) additionally
+  retains every frame's `Pix` slice for the lifetime of the returned `*GIF`.
+- `[INFERENCE]` On the 1974 MiB swapless VPS (root AGENTS.md), decoding such
+  a file would OOM rather than error cleanly; nothing in stdlib protects
+  the process. This matters for §7: the backend stores cover bytes without
+  decoding them (see §5.3), so the fetch path never triggers this — but any
+  future "validate/re-encode server-side" scheme would.
+- Grep for `MaxInt|limit|too large|bounds` in reader.go: the only hits are
+  the frame-bounds check above and the `tmp [1024]byte` scratch buffer
+  (reader.go:109); no size caps exist.
+
+### 4.2 giflib / libgif
+
+**Not verified from source.** On 2026-08-17 the giflib sources were not
+reachable from this network: `github.com/giflib/giflib` returns 404 (repo
+gone/moved), `gitlab.com/giflib/giflib/-/raw/...` answers a Cloudflare
+"Just a moment…" challenge, and the SourceForge project download path
+404s. No limit claim about giflib is made here. `[INFERENCE]` giflib is
+widely known to be allocation-driven with no dimension cap, but that is not
+checked against source and is not needed for issue #71 (the backend uses Go
+stdlib, not giflib).
+
+### 4.3 Chromium (browser behaviour, first-party source)
+
+- `third_party/blink/renderer/platform/image-decoders/gif/gif_image_reader.cc`
+  (via `chromium.googlesource.com/chromium/src/+/main/...`, fetched
+  2026-08-17): **no GIF byte-size or dimension cap found** — grep for
+  `max|limit|too large|dimension|65535|overflow` matches only license text.
+- The base `ImageDecoder` caps *decoded memory*, not transfer size:
+  `CalculateMaxDecodedBytes` computes `min(4 * num_pixels, platform_max_decoded_bytes)`
+  (8 bytes/pixel for high-bit-depth), and the header comment says "Ignoring
+  this limit can cause excessive memory use or even crashes on low-memory
+  devices"
+  (`image_decoder.cc:94-117`, `image_decoder.h:545-549`). The GIF reader
+  itself is untouched by this — it is a decoded-buffer budget.
+- Practical consequence `[INFERENCE]`: a browser will happily download and
+  store a multi-GB GIF from its own cache perspective; Chromium only limits
+  what it *decodes* into pixels.
+
+### 4.4 Firefox
+
+`image/decoders/nsGIFDecoder2.cpp` (via `hg.mozilla.org/mozilla-central/
+raw-file/tip/...`, fetched 2026-08-17): **no dimension or size limit**; the
+only guards are on LZW code width (`MAX_BITS` = 12, "maximum codeword size
+of 12 bits") and the decode stack. Nothing bounds the on-disk byte size.
+
+### 4.5 Summary
+
+No mainstream decoder enforces a byte-size ceiling; they stop at the 16-bit
+dimension ceiling (Go, by construction) or at decoded-memory budgets
+(Chromium) or nowhere (Firefox). A GIF's byte size is policed only by
+*storage* policies — which is what §6 calibrates and §7 sets.
+
+---
+
+## 5. Practical distribution — what real manga covers weigh
+
+Probed **2026-08-17** with `curl -sI` (HEAD) and ranged GETs, desktop Chrome
+UA. No Cloudflare block on any request. Sample = covers *as the backend
+would fetch them* (the `og:image`/page-listed cover URL), not thumbnails we
+chose by hand.
+
+### 5.1 Exact commands
+
+```sh
+# asurascans.com — harvest cover URLs from the homepage, then HEAD each
+curl -s -A "Mozilla/5.0 (Windows NT 10.0; Win64; x64) Chrome/126.0" https://asurascans.com/ -o home.html
+grep -oE 'https://cdn\.asurascans\.com/asura-images/covers/[^"&\\< ]+\.(webp|gif|jpg|jpeg|png)' home.html \
+  | sort -u | grep -v '\-400\.' | head -25 > sample.txt        # one full-res cover per series, no -400 thumbs
+while read -r u; do curl -s -A "…Chrome/126.0" -I "$u" | tr -d '\r' \
+  | grep -iE '^content-length:'; done < sample.txt
+
+# demonicscans.org — covers live on readermc.org (ADR-0007), URLs contain spaces/UTF-8
+curl -s -A "…Chrome/126.0" https://demonicscans.org/ -o demonic.html
+grep -oE 'src="https://readermc\.org/images/thumbnails/[^"]+"' demonic.html | tr -d 'src="' > demonic.txt
+# …plus og:image from 5 manga pages (Catastrophic-Necromancer, Magic-Emperor, …)
+# each URL percent-encoded per path segment (urllib.parse.quote, safe=':/') before HEAD
+```
+
+### 5.2 asurascans — 25 full-res covers (mixed formats)
+
+Homepage fetched 200 (664,700 B). All 25 returned `200` with a real
+`Content-Length`. Distribution:
+
+| Statistic | Bytes |
+|---|---|
+| n | 25 |
+| min | 190,410 |
+| median | 1,275,082 |
+| p90 | 4,524,788 |
+| max | 8,571,192 |
+| mean | 1,943,651 |
+| **> 4 MiB (4,194,304)** | **3 (12%)** — `a-dragonslayers-peerless-regression.gif` 8,571,192 (the issue #71 cover, animated: NETSCAPE2.0 at 0x310, 550×733, 256 colors); `bad-born-blood.3008f6.webp` 4,524,788 `image/jpeg`; `ending-maker.cfbf53.webp` 4,619,303 `image/jpeg` |
+
+Notes: the CDN serves `Content-Type` by stored bytes, not by URL extension
+(the `.webp` URLs return `image/png`, `image/jpeg`, or `image/webp` — the
+sample spans all four of `png/jpeg/webp/gif`). Two of the three over-cap
+files are **not GIFs**, so the current 4 MiB cap already silently drops 12%
+of asura covers of any format. p90 itself (4.52 MB) exceeds the cap.
+
+### 5.3 demonicscans — 78 covers on readermc.org
+
+78 unique cover URLs (73 from the homepage's `/images/thumbnails/` plus 5
+`og:image` values from manga pages — demonicscans publishes the thumbnail
+file as the full cover, so that is exactly what the backend would fetch).
+**78/78 returned 200 with a real Content-Length** (spaces and UTF-8 in the
+filenames were percent-encoded per path segment; the homepage's raw HTML
+carries `’`-style mojibake for curly quotes, which was repaired by
+latin-1→utf-8 re-encoding before probing).
+
+| Statistic | Bytes |
+|---|---|
+| n | 78 |
+| min | 13,298 |
+| median | 63,061 |
+| p90 | 206,994 |
+| max | 801,200 |
+| mean | 110,038 |
+| > 4 MiB | 0 |
+
+### 5.4 Reading
+
+`[INFERENCE]` asurascans covers are the heavy tail (median 1.3 MB, top
+decile > 4 MiB, occasional ~5–9 MB), demonicscans covers are tiny (all
+< 0.8 MB). A cover cap must be chosen against the *asura* distribution —
+the 8.57 MB animated GIF is not a freak one-off outlier; the 90th
+percentile already crosses 4 MiB and two JPEGs sit between 4.5–4.7 MB.
+
+---
+
+## 6. Comparable documented byte caps (first-party docs only)
+
+| Service | Cap | Source (fetched 2026-08-17) |
+|---|---|---|
+| GitHub (issues/PR comments) | **10 MB for images and gifs**; 25 MB other files; 10/100 MB video | `https://docs.github.com/en/get-started/writing-on-github/working-with-advanced-formatting/attaching-files` — "The maximum file size is: 10MB for images and gifs … 25MB for all other files" |
+| Discord (API uploads) | default **10 MiB per file**, higher with Nitro / boost tier | `https://discord.com/developers/docs/reference#uploading-files` — "The file upload size limit applies to each file in a request. The default limit is `10 MiB` for all users" (help-center article `support.discord.com/hc/en-us/articles/115002935588` exists but answered 403 from this network on the probe date, so its figures were not verified here) |
+| Wikimedia Commons | **100 MiB** upload limit; hosting up to **5 GiB**; GIF thumbnails limited to **100 megapixels**; prior 4 GiB host cap was a 32-bit storage artifact (phab:T191805) | `https://commons.wikimedia.org/wiki/Commons:Maximum_file_size` |
+| MDN | nothing — MDN documents no byte-size limit for images; browsers impose none (see §4.3–4.4) | `[INFERENCE]` from absence in the platform docs read in §4 |
+
+Calibration takeaway: two major platforms independently land on **~10 MB**
+as the ceiling for an uploadable image/GIF (GitHub exactly 10 MB, Discord
+exactly 10 MiB), with Wikimedia the outlier at 100 MiB/5 GiB because it is a
+media *archive*. A 10 MiB cover cap is therefore squarely inside industry
+normal.
+
+---
+
+## 7. Recommendation for issue #71
+
+**Raise the cover cap to 10 MiB (10,485,760 B) — as a separate constant, not
+by moving the shared one.**
+
+Why:
+
+- **Fits the measured reality.** The largest observed cover is 8,571,192 B
+  (the issue's animated GIF) = 82% of 10 MiB; 10 MiB covers **100% of the
+  103 sampled covers** and the *entire* asura distribution, including its
+  heavy tail. 4 MiB rejects 12% of asura covers (two of them plain JPEGs).
+- **Matches industry calibration** (§6): GitHub 10 MB images/GIFs, Discord
+  10 MiB default. A 10 MiB cap is a number every engineer recognizes, and
+  it leaves ~18% headroom over the current worst observed file.
+- **Costs little on the target hardware.** The backend buffers cover bytes
+  whole during fetch (`backend/internal/latest/cover.go`: `ContentLength >
+  maxBodyBytes` rejection at :155, then `io.ReadAll(io.LimitReader(…,
+  maxBodyBytes+1))` at :158) and loads the full body per `GET /covers/…`
+  (`backend/internal/api/handlers.go`, `Cover` → `w.Write(body)`). Worst
+  case per concurrent fetch **+** serve is therefore 2 × cap = 20 MiB; even
+  ten of each concurrently is ~200 MiB of a 1974 MiB swapless VPS (~10%),
+  and the browser unit (471 MiB, root AGENTS.md) is no longer on that box.
+  The 4 MiB series-page cap is *not* the issue — measured pages run
+  100 KB–1.2 MB (`backend/internal/latest/fetch.go` comment) — so keep it.
+- **The cap is a separate knob.** Today one `const maxBodyBytes = 4 << 20`
+  (`backend/internal/latest/fetch.go:17`) gates *both* series pages and
+  covers (`cover.go` references it). Raising it wholesale would loosen the
+  page-side memory guard for no benefit; a cover-specific constant (e.g.
+  `maxCoverBytes = 10 << 20`) keeps the two policies independent. The fetch
+  already double-checks `ContentLength` and the post-`LimitReader` length,
+  so a larger constant changes nothing else.
+
+Alternatives and their costs:
+
+| Option | Cost |
+|---|---|
+| Keep 4 MiB | 12% of asura covers (incl. non-GIF JPEGs) never stored — current bug, silent missing covers. |
+| 16 MiB cap | 2× headroom over the observed max for future GIFs; +60% worst-case transient memory vs 10 MiB; diverges from the GitHub/Discord 10 MB calibration. |
+| Server-side re-encode / downscale covers | Requires decoding → Go `image/gif` allocates width×height per frame with **no guard** (§4.1); a legal 65535² GIF forces a ~4.29 GB allocation on a 1974 MiB swapless box — OOM, not an error. Also mutates bytes, which the store treats as immutable/content-addressed (ADR-0007). Highest risk, no upside at this scale. |
+| No cap | Unbounded transient memory and disk; rejected outright. |
+
+Decision is the user's; on the evidence, **10 MiB for covers, 4 MiB for
+pages** is the defensible middle.

-## Knowledge Gaps
-- **524 isolated node(s):** `bookmarkmanager/backend`, `ctxKey`, `loginView`, `ctxKey`, `test` (+519 more)
-  These have ≤1 connection - possible missing edges or undocumented components.
-- **150 thin communities (<3 nodes) omitted from report** — run `graphify query` to explore isolated nodes.
-
-## Suggested Questions
-_Questions this graph is uniquely positioned to answer:_
-
-- **Why does `Open()` connect `Store Tests` to `Cover Fetch Test Helpers`, `Series Acquisition Tests`, `Bookmarks API Tests`, `Handler`, `displayChapter`?**
-  _High betweenness centrality (0.057) - this node is a cross-community bridge._
-- **Why does `New()` connect `Series Acquisition Tests` to `Bookmarks API Tests`, `Cover & Acquire Internals`, `Handler`, `Session Middleware`, `Store Tests`, `displayChapter`, `ResponseWriter`?**
-  _High betweenness centrality (0.051) - this node is a cross-community bridge._
-- **Why does `newRouter()` connect `Bookmarks API Tests` to `Cover Fetch Test Helpers`, `Series Acquisition Tests`, `Bookmarks API Handler`, `displayChapter`, `ResponseWriter`?**
-  _High betweenness centrality (0.031) - this node is a cross-community bridge._
-- **Are the 25 inferred relationships involving `newTestStore()` (e.g. with `TestAcquireDoesNotBlockTheWrite()` and `TestAcquireFailureLeavesTheBookmarkIntact()`) actually correct?**
-  _`newTestStore()` has 25 INFERRED edges - model-reasoned connections that need verification._
-- **Are the 48 inferred relationships involving `testConfig()` (e.g. with `TestListRendersAcquiredCover()` and `TestPublicCoverNeverEchoesNonImage()`) actually correct?**
-  _`testConfig()` has 48 INFERRED edges - model-reasoned connections that need verification._
-- **Are the 8 inferred relationships involving `newWebTestServer()` (e.g. with `TestListRendersAcquiredCover()` and `TestPublicCoverRejectsUnknownAddress()`) actually correct?**
-  _`newWebTestServer()` has 8 INFERRED edges - model-reasoned connections that need verification._
-- **What connects `bookmarkmanager/backend`, `ctxKey`, `loginView` to the rest of the system?**
-  _556 weakly-connected nodes found - possible documentation gaps or missing edges._

-Guidance for OpenCode (and Claude Code) working under `userscript/`. See root `AGENTS.md` for the project-wide architecture diagram, hard constraints, and design system.
+Scope: `userscript/`.
 
-### Userscript structure (single IIFE, `manga-bookmark.user.js`)
+Each entry names the code that holds the truth. The prose is only what the code
+cannot tell you: rationale, invariants a refactor would break, and dated
+observations about sites we don't control.
 
-1. **Site adapters** — one per host, `detect(location, document)` return page `type` + IDs. Identify type/IDs from **URL regex** (most stable); pull `title` from **`og:title`** (or the page heading where a site ships no og: tags), not CSS classes. **No adapter reads a cover**: the backend acquires, stores and serves every Cover from its own origin (ADR-0007), the wire's `cover` is already an address on our origin, and `apiPut` strips any `cover` off an outgoing body.
-2. **API client** — `apiGet/apiPut/apiDelete` with bearer header; `localStorage` key `bmgr:manga:cache` for instant render + offline fallback.
-3. **Progress logic** — auto-upsert `last_chapter` only when `chapterNum >= stored last_chapter_num` (re-reading old chapters must not regress progress; unparseable -> set current). Manual panel override forces any value.
-4. **Retry queue** — every write go through `pushBookmark`/`pushDelete`, so
-   failed mutation park in `localStorage` (`bmgr:manga:queue`) and replayed on
-   next navigation, reconnect, or `refresh()`. Entries are markers
-   (`{key, op, sendStatus, attempts}`), never payloads — body read from
-   cache at send time, so one entry per key give ordering and coalescing for
-   free. `sendStatus` is **sticky**: while archive pending, later writes to
-   that key keep carrying bucket, which stop successful
-   in-between write from silently un-archiving series. `refresh()` drains
-   before it fetches and overlays anything still pending, so list never
-   flaps. 400 drops entry, 401 abort pass and keep queue, and
-   transient failures retry to cap of 10. Latest-chapter writes deliberately
-   stay out of queue. See
-   `docs/superpowers/specs/2026-07-27-offline-retry-queue-design.md`.
-5. **UI** — rendered inside **Shadow DOM** root to isolate from site CSS
-   (critical on mobile). Three tabs (All / Favourites / Archived) and row of
-   link chips to web UI and both manga sites; `WEB_BASE` sits in CONFIG
-   block next to `API_BASE`. FAB is `7 × 44` edge tab whose *hit* area
-   widened to `28 × 72` by invisible `#hit` child; `#fab` must keep
-   `touch-action: none` and must **not** regain `overflow: hidden`. Since
-   `touch-action` resolved at gesture start, strip can't be both
-   browser-scrolled and script-dragged, so `makeDraggable` splits by intent: swipe
-   from `#hit` scrolls via `window.scrollBy`, hold of `ARM_MS` arms
-   reposition drag, visible sliver drags with no hold. See
-   `docs/superpowers/specs/2026-07-28-edge-tab-hitbox-design.md`.
-6. **SPA navigation** — Asura is Astro, client-routed on comic/chapter pages: patch `history.pushState`/`replaceState` + listen `popstate`, re-run `detect()` on URL change so auto-update fire without reload. Demonic uses classic reloads (initial `document-idle` run suffice).
+### Structure — single IIFE, `manga-bookmark.user.js`
 
-### Live URL shapes (verified 2026-07-26, may drift — re-check against live pages before trust)
+Six parts, in file order: site adapters, API client, progress logic, retry
+queue, UI, SPA navigation.
 
-- **asurascans.com**: series `/comics/<slug>` (slug carries trailing
-  site-wide build-hash suffix, e.g. `-059befe1`, that **rotates on every
-  redeploy**), chapter `/comics/<slug>/chapter/<n>`. `seriesId` must strip
-  hash (`/-[0-9a-f]{8}$/`, `stripBuildHash` in userscript,
-  `asuraBuildHash` in backend); URLs keep full slug — stale-hash
-  URLs 302 to current ones. Astro-rendered; chapter links present in raw
-  server HTML.
-- **demonicscans.org**: series `/manga/<slug>` (slug may URL-encode punctuation, e.g. `%2527` for `'`), chapter `/title/<slug>/chapter/<n>/<page>` (older `chaptered.php?manga=<id>&chapter=<n>` form still exists as redirect, what series-page chapter-list anchors link through).
-  Encodings (incl. triple-encoded punctuation like `%25252D`) identical
-  on /manga/ and /title/ pages, so decode-once seriesIds match — verified
-  2026-07-28.
-- **comix.to**: series `/title/<id>-<slug>`, chapter
-  `/title/<id>-<slug>/<uploadId>-chapter-<n>`. Only the leading `<id>` is
-  identity — the slug re-renders when a series is renamed (`comixSeriesId`).
-  An SPA that **never rewrites `og:title`**: the server-rendered head keeps
-  whatever document loaded first, so on a cold load `og:title` is the homepage's
-  "Comix — Read Comics online for free" and after an in-page hop it is the
-  *previous* series' name. `document.title` is the one thing client routing does
-  update, so titles come from there, with the chapter page's `" · Ch.<n>"` tail
-  stripped. It publishes no `og:image` either, which is one of the reasons cover
+**Site adapters** — one per host, `detect(location, document)` returning page
+`type` + IDs.
+
+- Identify type and IDs from **URL regex**, which is the most stable surface a
+  site exposes; take `title` from **`og:title`** (or the page heading where a
+  site ships no og: tags), never CSS classes.
+- **No adapter reads a cover.** The backend acquires, stores and serves every
+  Cover from its own origin, the wire `cover` is already an address there, and
+  `apiPut` strips any `cover` off an outgoing body.
+
+**Progress logic** — auto-upsert `last_chapter` only when
+`chapterNum >= stored last_chapter_num`; unparseable sets the current value.
+Re-reading an old chapter must not regress progress. A manual panel override
+forces any value.
+
+**Retry queue** — every write goes through `pushBookmark`/`pushDelete`.
+
+- Entries are markers (`{key, op, sendStatus, attempts}`), **never payloads**:
+  the body is read from cache at send time, so one entry per key gives ordering
+  and coalescing for free.
+- `sendStatus` is **sticky** — while an archive is pending, later writes to that
+  key keep carrying the bucket. Without it a successful in-between write
+  silently un-archives the series.
+- `refresh()` drains before it fetches and overlays anything still pending, so
+  the list never flaps.
+- 400 drops the entry, 401 aborts the pass and keeps the queue, transient
+  failures retry to a cap. Latest-chapter writes deliberately stay out of the
+  queue.
+
+**UI** — rendered inside a **Shadow DOM** root to isolate it from site CSS,
+which is critical on mobile.
+
+- The FAB's *hit* area is widened by an invisible `#hit` child. `#fab` must keep
+  `touch-action: none` and must **not** regain `overflow: hidden`.
+- `touch-action` is resolved at gesture start, so the strip cannot be both
+  browser-scrolled and script-dragged. `makeDraggable` therefore splits by
+  intent: a swipe from `#hit` scrolls via `window.scrollBy`, a hold of `ARM_MS`
+  arms a reposition drag, and the visible sliver drags with no hold.
+
+**SPA navigation** — Asura is Astro and client-routes on comic/chapter pages, so
+`history.pushState`/`replaceState` are patched and `popstate` listened to, and
+`detect()` re-runs on URL change. Demonic uses classic reloads, where the
+initial `document-idle` run suffices.
+
+### Live URL shapes
+
+Encoded in the adapters; the notes below are the parts a reader of the regex
+would get wrong. **Verified 2026-07-26 unless dated otherwise — sites drift, so
+re-check against a live page before trusting any of it.**
+
+- **asurascans.com** — the series slug carries a site-wide build-hash suffix
+  (e.g. `-059befe1`) that **rotates on every redeploy**, so `seriesId` must
+  strip it (`stripBuildHash` here, `asuraBuildHash` in the backend) while URLs
+  keep the full slug — stale-hash URLs 302 to current ones.
+- **demonicscans.org** — slugs may URL-encode punctuation, and the older
+  `chaptered.php?manga=<id>&chapter=<n>` form still exists as a redirect, which
+  is what series-page chapter-list anchors link through. Encodings (including
+  triple-encoded punctuation like `%25252D`) are identical on `/manga/` and
+  `/title/` pages, so decode-once seriesIds match (verified 2026-07-28).
+- **comix.to** — only the leading `<id>` is identity; the slug re-renders when a
+  series is renamed (`comixSeriesId`). It is an SPA that **never rewrites
+  `og:title`**: the server-rendered head keeps whatever document loaded first,
+  so on a cold load `og:title` is the homepage's name and after an in-page hop
+  it is the *previous* series'. `document.title` is the one thing client routing
+  updates, hence titles come from there with the chapter page's `" · Ch.<n>"`
+  tail stripped. It publishes no `og:image` either, one of the reasons cover
   acquisition moved to the backend.
-- **kagane.to**: series `/series/<uuid>`, reader
-  `/series/<uuid>/reader/<bookUuid>`. Reader URLs carry no chapter number, so
-  the number comes out of `og:title`. Two shapes exist: `"<Series> - Chapter
-  <n>[ - Episode <n>]"` and, for volume-numbered series, `"<Series> - Volume <v>
-  Chapter <n>"` with no episode name — both must yield a bare series title, or
-  the volume tail lands in the bookmark's title.
-  Its covers are challenge- and CORP-protected, so nothing outside kagane.to can
-  load one directly; the panel renders the backend's own cover address like every
-  other Site. Behind a Cloudflare JS challenge, so the backend polls it
-  through the headless browser.
-- **novelfull.com** (novel script): series `/<slug>.html`, chapter
-  `/<slug>/chapter-<n>[-<title-slug>].html`. No `og:*` tags at all — title from
-  `h3.title` (series) or `a.truyen-title` (chapter); the script reads no cover.
