Merge #159: Finished joins the admin filter vocabulary

finished_at lands on series (0016 seeds it from the pre-flip finished
bookmarks, then flips those bookmarks to archived), the poll gate and
eligible count read the flag instead of a per-Reader vote, PUT rejects
the finished status like any unknown value, and the web UI drops the
Finished tab, badge and finish button. Novel merge rank is archived >
reading. Per-Reader disagreement (one Reader keeps a finished Series in
reading forever) is what the flag repairs; the cutover keeps polling
state unchanged for every Series.

+# 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.
