Analytics charts: translucent typical fill, last-week tail on week view

Render the seasonal typical estimate as a translucent muted fill (no
stroke, same 0.6 opacity as the data) instead of a grey line, on both day
and week views. Continue the fixed Monday-Monday week view with last
week's curve from the current bucket to the end of the week (secondary
accent, translucent fill), so the chart is useful early in the week and
last week is gradually replaced by the current one.

Gate the typical estimate on history spanning twice the view's full time
(third day / third week on) and the last-week tail on data reaching into
last week at all; the legend shows each entry only when present.

-## What is collected
+## Raw records
+
+The store is deliberately close to an access log: two append-only lists plus
+shared metadata. **Nothing is classified when recorded** — whether a client
+turns out to be a reader, a crawler or a scanner is decided by
+`Store.display()` from the raw events, so the stored data survives any future
+change to the classification rules.
+
+Each `Get` record (one per served document):
+
+- `t` — timestamp of the request,
+- `path` — full request path, query string included (e.g. `/.env?x=1`),
+- `status` — the true HTTP status of the response (200, or 404 for a category
+  placeholder or a missing page),
+- `ref` — external https origin of the `Referer`, `""` for direct/internal
+  (same-origin referers are dropped by the recorder),
+- `pre` — true for idle-time link preloads from pagerite.js
+  (`x-pagerite-preload` header): never counted as a view, crawler hit or
+  abuse — recorded only so a navigation later served from the in-memory page
+  cache (which issues no GET at all) can be attributed this GET's status,
+- `lang` — rendered content language of the served document (the resolved
+  language of a localized page), `""` for non-localized responses (404
+  probes, reserved paths),
+- `client` — 6-byte blake3 hash referencing `Analytics.clients`.
+
+304 revalidation responses return before recording and are not logged.
+
+Each `Msg` record (one per pagerite.js activity message over `/_ws`):
+
+- `t` — timestamp,
+- `client` — 6-byte blake3 hash referencing `Analytics.clients`,
+- `fr` — path of the page the activity happened on (`""` for the initial
+  load),
+- `to` — navigation target (validated at record time: internal slug path or
+  external https URL; anything else is dropped — sanitation, not
+  classification),
+- `read` — active seconds spent on `fr` since the previous report,
+- `lang` — rendered language reported by the client for the page the
+  activity happened on (the page's `<html lang>`; `""` from old clients).
+
+Each `Client` record (shared by every event, keyed by hash):
+
+- `ip` — visitor IP address (first `X-Forwarded-For` hop, or direct peer),
+- `host` — reverse-DNS host name for `ip` when resolvable, else `""`,
+- `lang` — first `Accept-Language` tag, lowercased (e.g. `"en-us"`),
+- `country` — two-letter country code.  Initially derived from the
+  `Accept-Language` region subtag, but overwritten by the DB-IP MMDB result
+  when a database is available,
+- `city` — city name from the DB-IP MMDB lookup, when available,
+- `ua` — raw `User-Agent` string,
+- `hide` — true for admin clients (`hide` message field): everything this
+  client ever did is recorded but excluded from every statistic and from the
+  viewer payload.  This is the one flag set at record time — it is a client
+  property, not a classification.
+
+The viewer payload adds one display-time field to each client, never
+persisted (stored records keep the default and old data always follows the
+current uarite version):
+
+- `uarite` — the `uarite.UA` dataclass from parsing the raw UA
+  (`pretty`/`engine`/`os`/`provider`/`kind`/`url`): the crawler name for
+  bots,
+  with a category suffix only where a provider runs crawlers of more than
+  one kind (`GPTBot (AI)` vs `OAI-SearchBot (search)`, `Googlebot (search)`
+  vs `Google-Extended (AI)`; single-kind providers stay plain: `Facebook`,
+  `WhatsApp`), `Browser/major OS` on the desktop, the device where that is
+  the relevant information (iPhone reports its iOS version, Android phones
+  their model instead of the OS), otherwise the raw string; `url` is the
+  crawler's info page when uarite knows one (rendered as a 🔗 link after the
+  pretty UA in the viewer), `kind` drives the bot classification.
+
+A reverse-DNS lookup is attempted for each new client and the result, when
+available, is stored as `host`; local/reserved/multicast addresses are
+skipped.  If a DB-IP MMDB file (`dbip-*.mmdb` or `dbip-*.mmdb.gz`) is present
+in the working directory, it is loaded at startup and used to look up
+`country`/`city`.  These lookups run in background tasks after the event is
+stored, so WebSocket message handling is never delayed.  Only the downloaded
+`.mmdb.gz` is kept on disk (in the working directory, ignored by git); it is
+decompressed into RAM when opened.  The
+CLI flag `--dbip` (`uv run pagerite --dbip`) downloads the latest
+`dbip-city-lite-YYYY-MM.mmdb.gz` from DB-IP at startup (in the app lifespan,
+before the MMDB is opened), skipping the download when the local database is
+already current and removing older versions after an update; without the flag
+only an existing file is used.
+
+## What the client sends
 
 The client (`pagerite.js`) keeps a WebSocket connection to `/_ws` for the
 whole browsing session and sends activity messages over it — JSON text
 frames matching the server's `Ping` msgspec struct with the fields `fr`
 (source path), `to` (navigation target), `read` (active seconds on `fr`

-  (`_MIN_VISIT_READ`; durations are client-provided and trusted — such bots
-  report 0–2 s) is reclassified as crawler hits at display time, one hit
-  per internal trail page, and counts in no visit aggregate.  The
-  `Accept-Language` header is stored on the shared
-  `Client` immediately; reverse-DNS host names and DB-IP geoip
-  country/city are filled in asynchronously, just like for real visits.  In
-  the analytics viewer, crawler hits are grouped by client hash and shown as
-  a trail of internal pages that crawler visited, preceded by its referer
-  when there is one — spiders often advertise their own site as the
-  referer, and it is rendered with its favicon like visit referers (crawler
-  referers are included in the favicon fetch origins).  The crawler table lists
-  the most recent crawler first, with the most active as a tie-breaker.
-- **Abuse (scanner) hits**: a 404 for a telltale path — any URL segment
-  starting with a dot (`/.env`, `/.git/config`) or ending in `.php` —
-  classifies the source IP as abuse immediately, and ten plain 404s from one
-  IP do too.  Classification reclassifies history: all earlier crawler hits
-  from that IP (persisted and pending) move to the `abuse` list, so a
-  random-UA scanner no longer pollutes the crawler stats of the legitimate
-  bot it impersonates.  Once classified, every document GET and 404 from the
-  IP is recorded as an abuse hit with the full request path (query string
-  included), and its activity messages are ignored.  The classified IP set (`abuse_ips`)
-  is persisted in the JSON file; the plain-404 counters are RAM-only.  In the
-  viewer, abuse hits are grouped by IP (never by client/UA — scanners
-  randomize theirs) in a separate "Abuse" table.  Identical paths are
-  collapsed into one entry with their hit count.  The 404 probes ("paths
-  abused": flagged paths that triggered classification first, then other
-  404s) are kept in a separate column from the real articles the abuser
-  actually read ("articles read": document GETs that returned 200, not the
-  404 fallback rendering — rendered as trail links like the visitor and
-  crawler tables, with the query string stripped).  Raw User-Agent strings are shown one

+  allows 404 pages to render red in the viewer even when the navigation
+  itself was served from the page cache. Each trail item also carries the
+  rendered language: the client's report, for the entry page falling back
+  to its GET's rendered language (old clients don't send one); a page
+  re-visited in a different language becomes a distinct trail step instead
+  of merging into the existing item. The entry page's referer and
+  `utm_*` tags come from the GET that loaded it (within 10 s before the
+  first message).
+- **Crawler hits**: a document GET no activity message matched within
+  `_CRAWLER_TIMEOUT` (10 s) is a crawler hit — plain bots that only fetch
+  documents never register as visits. JS-running crawlers (Googlebot,
+  GoogleOther, Applebot, ...) do connect and send messages, but their UA
+  gives them away (`_is_bot_ua`, backed by `uarite.uaparse` — which
+  also knows the disguised ones: facebookexternalhit, Google-Extended,
+  WhatsApp, ...): their messages are ignored at display
+  time, so their GETs never match and land in the crawler list too. Real-
+  browser bots whose UA does not match are caught by engagement: a visit
+  whose total reported reading time is under 5 seconds (`_MIN_VISIT_READ`;
+  durations are client-provided and trusted — such bots report 0–2 s) is
+  reclassified as crawler hits, one per internal trail page, and counts in
+  no visit aggregate. No source-IP verification is done: a spoofed bot UA
+  merely lands in the crawler stats, and scanners that probe telltale paths
+  are caught by the abuse rules regardless. In the viewer, crawler hits are
+  grouped by client hash and shown as a trail of pages, preceded by the
+  referer when there is one (rendered with its favicon like visit
+  referers). The crawler table lists the most recent crawler first, with
+  the most active as a tie-breaker.
+- **Abuse (scanner) hits**: a 404 on a telltale path — an empty URL segment
+  (`//foo` — no real client generates those), any segment starting with a
+  dot (`/.env`, `/.git/config`) or ending in `.php` — classifies the source
+  IP as abuse, and ten plain 404s within one hour (`_ABUSE_404_WINDOW`) on
+  paths that don't resolve to a menu node do too. Two exemptions keep
+  legitimate traffic out: RFC 8615 well-known URIs (`/.well-known/…` —
+  browsers and services probe them, e.g. Chrome's devtools fetch of
+  `appspecific/com.chrome.devtools.json`) are never telltale and never
+  count toward the threshold, and category placeholders return 404 but are
+  real menu nodes, so they never count either. The window keeps a
+  long-time reader's slowly accumulating misses from ever crossing the
+  threshold — scanners spray in bursts. Hidden (admin) clients never
+  trigger classification: editing means visiting not-found pages, since
+  that is where the create pen lives. Once an IP is classified, **all** its document GETs are shown in the abuse list —
+  including any that arrived before classification, since the raw log keeps
+  everything — and its activity messages are ignored. In the viewer, abuse
+  hits are grouped by IP (never by client/UA — scanners randomize theirs)
+  in a separate "Abuse" table, split by the recorded status: the 404 probes
+  ("paths abused" — flagged paths that triggered classification first, then
+  other 404s, shown verbatim with query strings) versus the real articles
+  the abuser actually read ("articles read" — the 200 document GETs,

Built in: `{dates}` expands to the article's published/updated dateline (`p.dateline`, from `Node.created`/`modified`, registered by `render()` when `created` is given); views.py resolves `{cards}` — the page's published children, one card each (on the front page: the other top-level pages) — and `{cards: path path/* path/** ...}` (space-separated: a plain path renders that page alone, `path/*` its published children, `path/**` all published descendant pages; a page-less item is represented by its first leaf page, the nav-link logic) into the same card-row markup as category pages (`.cards.wide`, a boundary block outside the column segments).

 The navbar holds top-level items only; the current section's subitems go to a left `#sidebar` as a nested list (the section's direct children plain, deeper levels indented with article-list-style markers), rendered only from the second level down — main-level pages list their children as cards after the content instead. Below that, the sidebar renders when the section offers at least two published items, or exactly one while viewing anything other than that only page — the section index, a 404, a grandchild (so those pages can reach the child), and also on that only page itself when it has published children of its own; no aside element at all on the front page, main-level pages, leaf pages and the sole childless page of a one-page section. Also, category labels are nodes without content — None *or* empty markdown — and their nav links point at their first child page.

Fenced code blocks are highlighted server-side with **Pygments** (`nowrap` spans styled by `/_assets/pygments-*.css`, which maps every token class onto the `--code-*` variables; the base stylesheet defines light and dark palette sets resolved via `light-dark()`, so each theme gets the set matching its `color-scheme` and may only retint `--code-bg` to keep the well in the page's color family); a JS copy button appears on hover. Should this prove limiting, we implement our own renderer on top of html5tagger, which we already use for all HTML generation.

 ## Page structure and navigation
 
 - All pages share one static layout, defined once as an **html5tagger Template** with capitalized placeholders (`Title`, `Banner`, `Nav`, `Sidebar`, `Main`) filled per request. The dynamic regions carry stable ids (`#page-banner`, `#nav`, `#sidebar`, `#main`).
 - The page top is a **full-width banner header** with the site name and the navigation bar overlaid on it — no separate chrome header. The banner combines two layers, stacked in `#page-banner` (a grid, so they overlay): first the **banner design** — a named design living in a theme folder (`pagerite/themes/{name}/banner.css` plus artwork as `banner.html` — arbitrary markup like canvas + style + script — or `banner.svg`), chosen per page via `Node.banner_design` (a design name, "" for none, None to inherit from the nearest ancestor, then the front page, then the active theme's own design). The artwork is inlined into a `div[data-design]` wrapper: SVG artwork can be recolored from the theme stylesheet (corporate's single SVG serves both light and dark mode via `var()`-driven stops). Second, **per-page author code**: `Node.banner` holds an arbitrary trusted HTML snippet (an image, a styled div, canvas + script — anything), resolved by walking up the node's ancestors to the front page and rendered **after** the design artwork, so author styles always win over the design's own. The base stylesheet falls back to a plain gradient. There is deliberately no scrim fading the banner into the page background — any such fade would ruin user-supplied designs; themes that want one bake it into their SVG (purple does).
 - **Fetch-navigation.** Links are plain `<a href>`; a small script (`frontend/src/pagerite.js`) intercepts same-origin clicks, fetches the page, and swaps the `#page-banner`, `#nav`, `#sidebar` and `#main` regions, the document title, and the site-wide custom CSS (`<style id="pagerite-user">` in `<head>`), keeping the rest of `<head>` and the layout chrome. Without JS everything works as normal page loads. Scripts inside fetched banner and content regions are re-created so they execute. Swaps run inside `document.startViewTransition` for the page transition selected in the site settings (`Data.transition`; the `cube` design — CSS adapted from termotohtori.fi, fragile, do not tweak — rotates, mirrored on browser back; `crossfade` fades; both skipped under `prefers-reduced-motion`). With `cube`, navigation within the same top-level section crossfades instead of rotating.
-- **The site structure is a tree of labels.** `Data.menu` holds the top-level items by slug, each with `children` keyed by slug — the URL path is the slug chain. The front page is a top-level node with slug "" (an item *parallel* to the other main level pages, not their parent) and cannot have children. The header navbar holds only the top level; a top-level item is highlighted when viewing any of its subpages. A page with published children lists them as **cards** after its content (the child page's share image as the cover, like the og tags, with the title overlaid); a **left sidebar** (`#sidebar`) with the section's sub-navigation appears only from the second level down, when there is something to navigate — main-level pages, sections with fewer than two published items, leaf pages and the front page render no aside element at all. Other sections' subitems are never shown without navigating into them first.

Other sections' subitems are never shown without navigating into them first.
 - **Landing pages are optional.** Every label can either have content (`Node.content`, a Markdown page) or none — a content-less label renders a 404 page listing its children as cards (with a pen to create the landing page) instead of redirecting, while nav links to it point straight at its first child, so categories need no filler content and normal navigation never sees the 404. Title and slug of every label are editable; renaming a slug moves the whole subtree. The sidebar never lists the section itself, avoiding title duplication with the navbar.
 - **Menu order is manual.** Each node has a fractional `order` key among its siblings; reordering/moving writes only the moved node (it takes a fresh value halfway between its new siblings; all other items keep theirs). New pages append at the end of their menu. Structure edits (reorder, move/rename with the whole subtree, retitle) go through `POST /_api/structure` and the editor's structure panel.
 - Unpublished pages are hidden from both nav and URL access (404).

Below it, the site's own cards preview in both modes (small and large) with the real `.card` markup and styles from pagerite.css — theme variables included, they are the site's look — scaled down via font-size (the card internals are all em, so the layout proportions match real cards exactly); both render the effective card image (the resolved node image, else the image the server mines from the article), and the description appears only in the small format, like the backend's `_card`. The previews double as the card-mode selector for the per-article `Node.large` override: clicking one forces that mode (thin solid outline), clicking the selected one returns to automatic; under automatic the mode auto currently resolves to gets a dashed marker (both outlines — selection never shifts the layout), approximated from image presence only (the server's dimension probe is not available in the panel).

 Media uploads everywhere use the image icon buttons (pasting into the editor works too). The article, banner and site-settings pens are shorthands that open the shell on the matching tab; once open, clicking a pen switches tabs (and retargets the editors to the current page) instead of closing/remounting. The close button in the tab bar closes the shell (deliberately NOT Escape — it fired too easily by accident); tabs have no close buttons of their own. Closing only HIDES the shell — the Vue app stays mounted, so page-editor state (unsaved text included) survives until a real page reload; the editor always follows the URL, so fetch-navigating with the shell open (or before re-opening it) retargets it to the new page — unsaved text is stashed per path for the session and restored when returning, cleared on save. Saving there is explicit (Ctrl+S) and refreshes the page regions in place. Admin panels never reload the page.

 Asset wiring differs by mode. In dev the backend links the Vite dev-server URLs (`pagerite:editor-src`/`-css`/`pagerite:analytics-src` meta tags, `<link>` stylesheets) and Vite injects the entry CSS from JS for hot reloads. In production there are no pagerite meta tags: all page assets are inlined into the document — stylesheets as `<style>` elements in `<head>` (fixed order: base, theme, banner design, page transition, entry sheets, custom CSS last), module scripts as inline `<script>`s at the end of the body (relative chunk imports are rewritten to absolute `/_assets/` paths) — and the on-demand bundles' URLs ride in a `<script type="application/json" id="pagerite-assets">` config. The editor bundle always stays external, imported on demand when a pen is opened. Every stylesheet element carries a stable id so fetch-navigation and the site editor can sync `<head>` positionally across swaps (the analytics sheet exists on `/_a` only and is added/removed as you navigate). The analytics entry is inlined into the `/_a` page itself; pagerite.js re-creates that script element after fetch-navigating there (inline scripts don't execute on a DOM swap) and calls the module's exposed unmount before swapping away.

+
+Design for augmenting the fragment-based machine translation
+(docs/localization.md) with general-purpose instruct LLMs that understand
+Markdown natively — as opposed to pure text-to-text models like Seed-X.
+
+## Motivation
+
+The chunk + segment pipeline (`chunks.py` → `segments.py` → Seed-X) exists
+because Seed-X mangles Markdown: links, formatting, fences and placeholders
+must be stripped before dispatch and re-inserted into the result. The
+re-insertion of link and formatting markup is the imprecise part: when
+word-alignment by form similarity finds no anchor (always for CJK targets),
+positions fall back to word-weight ratios, which land a word or so off.
+All of `segments.py` — segmentation, offset splicing, `_find_mark`,
+weight-ratio fallback, `_NEUTRAL` punctuation swaps, `<` encoding — is
+defensive scaffolding around that one limitation.
+
+An instruct LLM translates Markdown natively: `[text](url)` stays intact
+and moves as a unit, fences, container markers, attrs and `{...}`
+placeholders are preserved, and link texts translate in sentence context.
+For such a translator the entire segments layer is unnecessary.
+
+## Trial evidence (2026-09, RTX 4090 24 GB + 128 GB RAM, ollama 0.34)
+
+Whole-article translation of two real articles (5.5 KB marketing, 18.3 KB
+technical with code fences and `{dates}`) into fi/es/zh:
+
+- **qwen3.8:27b** (dense, 17 GB Q4 — fits VRAM): structure-perfect on all
+  runs — URLs, placeholders, heading/block counts preserved, fenced code
+  byte-identical. es/zh excellent; fi fluent with occasional lexical slips
+  (covered by the human override layer). ~30 s per short article, ~2.5 min
+  for 18 KB. **The reference model for article and markdown modes.**
+- **qwen3:30b-instruct**: 3× faster, good prose, but rewrote comments and
+  docstrings inside code fences despite explicit instructions — fails
+  anchor validation (see below).
+- **qwen3-next:80b** (MoE): best Finnish word choice on short documents,
+  but degenerates on longer input in every configuration tried — runaway
+  thinking loops (293k tokens), empty responses, 3× length output with
+  hallucinated URLs, and ~10× blowup even in 2 KB scoped chunks. Unusable
+  on current ollama builds.
+- **CPU-only** (i7-14700, 14 threads): MoE 3B-active 10.6 t/s generation
+  (viable for batch), dense 27B 2.5 t/s (not viable). Hybrid GPU+CPU
+  splits bottleneck prompt evaluation (~52 t/s vs 62 t/s pure CPU) —
+  dense GPU-resident or MoE CPU-resident are the sane configurations;
+  mixing hurts.
+
+Operational requirements established by the trials (all client-side):
+
+- **Always disable thinking** for hybrid models (`think: false` on
+  ollama): the reasoning phase adds minutes per article and can loop
+  unbounded.
+- **Always cap generation** (`num_predict` ≈ 2–3× input tokens): a
+  runaway on a whole-article job burns hours, vs. seconds for a
+  Seed-X segment.
+- temperature 0.2 with the strict structure prompt works well for
+  qwen3.8.
+
+## What carries over unchanged
+
+The valuable parts of the current design are the **storage and staleness
+model**, not the segmentation — and none of them require the machine
+translation to be produced chunk by chunk. The chunk store is a
+storage/diffing format; LLM output at any granularity is *projected
+into* it:
+
+- Content-addressed source chunks (`Data.chunks`, `chunk_key`) — staleness
+  still falls out of source-hash keys: editing the original invalidates
+  exactly the edited chunks, all other translations keep applying.
+- Per-chunk machine translations (`Data.trans[hash][lang]`) and the hybrid
+  render with per-chunk fallback to the original.
+- User overrides (`Data.overrides`) — per-original-chunk edits
+  (search/replace pairs, drops, anchored additions) applied structurally to
+  the assembled hybrid, each independent and best-effort. Overrides are
+  orthogonal to how `Data.trans` entries were produced.
+- `pending_items`: after a source edit, exactly the changed (lang, hash)
+  pairs are pending — **focused retranslation of edits falls out of the
+  existing bookkeeping**, no whole-article reruns.
+
+## Protocol: capabilities and job modes
+
+The `/_translate/{key}` WebSocket stays the single channel; Seed-X
+clients work unchanged. The client→server `Hello` gains two optional
+fields:
+
+```python
+class Hello(msgspec.Struct, tag="hello"):
+    langs: list[str]  # as today: languages the model can produce
+    model: str = ""  # free-form model string (logging, debugging)
+    modes: list[str] = ["segments"]  # job granularities accepted
+```
+
+Four job modes, in increasing granularity:
+
+- **`segments`** — the current protocol, unchanged: `Job.texts` carries
+  prose segments (markup never crosses the wire), `Result.texts` returns
+  them, the server splices by offset (`segments.py`). For text-to-text
+  models (Seed-X). Default when a client omits `modes`.
+- **`markdown`** (scoped instruct mode) — one fragment as full Markdown:
+  a body chunk or a title. `Job.texts` carries a single element, the
+  chunk's Markdown; `Job.contexts` carries up to two context strings
+  (previous and next block of the **served hybrid** in the target
+  language — current machine translation with user overrides applied),
+  "" where none. The client is instructed to output ONLY the translation
+  of the target block; the context is terminology/tone reference.
+  Using the *overridden* hybrid as context propagates human corrections
+  into fresh machine translations without the LLM ever touching override
+  storage. `Result.texts` carries one element, the translated block.
+  The server validates: exactly one block after re-chunking, anchor
+  constructs (URLs, image destinations, code fence content, `{...}`
+  placeholders) preserved where the source block has them, then stores
+  to `Data.trans` as usual.
+- **`article`** — a whole page. `Job.texts` carries one element, the full
+  original Markdown (the chunk sequence is recoverable server-side via
+  `node.chunks`); `Result.texts` carries one element, the full translated
+  Markdown. The server decomposes (below) and stores per chunk.
+- **`nav`** — the whole navigation hierarchy. `Job.texts` carries one
+  element, a nested Markdown list of every node title still pending for
+  the language (`- Title`, indented by depth, in menu order);
+  `Result.texts` carries one element, the translated list. The server
+  decomposes by list structure (`align_nav`): item count and nesting
+  depth must match the source item for item, then each item is stored as
+  a per-title fragment under its title's chunk hash.
+
+Titles are jobs like any other in all modes (`kind="title"` keeps its
+article-opening context rule; in `markdown` mode a title crosses as
+plain text, since it carries no markup by construction) — but for
+nav-capable connections a single `nav` job names the entire menu first:
+one round trip instead of one per page, with siblings, parents and
+children translating in sight of each other. A structurally mangled list
+is rejected wholesale and the titles fall back to scoped title jobs.

+`article` job carries the page title injected as a `# {title}` line at
+the top when the render would inject it (the body has no h1 of its own):
+the title translates in document context and the opening paragraphs see
+the heading. The menu title's and parent node's existing translations
+ride along as `Job.contexts` ("" where none), so the heading can match
+the menu while the model may still adapt the in-article title to the
+content. The heading's pair in the decomposed result becomes the
+title fragment (heading text only, never stored as a body chunk).
+
+### Dispatch and validation
+
+- Routing is per connection as today (wanted ∩ capable, one job in
+  flight, requeue on disconnect), extended by mode: the smallest
+  suitable unit goes to each free connection — `article` jobs only to
+  article-capable connections, and only while a page is *mostly*
+  pending (a whole new article or a full refresh); steady-state edit
+  follow-up is `markdown`/`segments` jobs. Mixed translator fleets (a
+  Seed-X instance, a local qwen, an API-backed client) run concurrently
+  and share the work by capability.
+- The validation skip-list becomes **mode-scoped** (`(lang, key, mode)`):
+  a fragment a Seed-X client rejects stays offerable to instruct clients
+  (and vice versa) — near-deterministic re-failure applies per model,
+  not across approaches.
+- `Result` matching is unchanged (lang, key); article results match on
+  the key of the article's first chunk.
+
+## Article result decomposition
+
+1. Re-chunk the translated article with the same `chunk_markdown`.
+2. Align translated blocks to source blocks. A well-behaved model does
+   not reorder paragraphs, so positional / `SequenceMatcher` alignment
+   at block granularity suffices. Blocks that must not change — code
+   fences, container fence lines, `{...}` placeholders, image
+   destinations, raw HTML — are matched verbatim and serve as alignment
+   anchors, like diff context lines.
+3. Store each translated block in `Data.trans[source_chunk_hash][lang]`.
+
+Validation happens *before* anything is stored, same spirit as the
+`pure_prose` segment checks but structural:
+
+- Anchor blocks must appear verbatim and in order (this is what rejects
+  qwen3:30b-instruct's translated code comments automatically).
+- Per anchor-bounded region, source and translated block counts must
+  match 1:1; regions that don't align store nothing and their chunks
+  stay pending (they fall back to `markdown`-mode scoped jobs).
+
+## Reference client
+
+A second client script next to `scripts/translator.py` speaking the
+`markdown` and `article` modes. Internally it targets the **OpenAI
+Chat Completions API shape** (`POST /v1/chat/completions`): ollama
+serves it at `:11434/v1`, llama.cpp's server likewise, and hosted APIs
+(OpenAI and compatible providers) natively — `--base-url` + `--model`
+selects local GPU, local CPU or a remote model, the API key comes from
+the standard per-provider environment variable (`KIMI_API_KEY`,
+`MOONSHOT_API_KEY`, `OPENAI_API_KEY`, each sent only to its own
+provider's host; `LLM_API_KEY` for anything else) — deliberately never
+a CLI flag or a config file — and backend quirks (ollama's
+`think: false`, `num_predict` cap, per-model sampling) live in the
+script's `DEFAULT_CONFIG`.
+How the client drives its LLM is its internal matter; the wire protocol
+above is the contract.
+
+Field-proven backends: the local qwen3.8:27b of the trials above, and
+the **Kimi Code API** (`--base-url https://api.kimi.com/coding` resp.
+`api.kimi.ai`, `--model k3-256k`): the `/coding` endpoint fixes sampling
+internally (the client drops `temperature`/`top_p` for it — they 400)
+and runs `reasoning_effort: low` from the config, which produces good
+translations at a fraction of the default (high) effort's latency and
+quota; thinking output is logged verbatim but stripped from the result.
+
+The client announces in `Hello`:
+
+- `model`: the model string it is actually serving (e.g. `qwen3.8:27b`)
+- `langs`: from its per-model language table — for the shipped qwen3.8
+  configuration the site languages as configured server-side
+  (de, es, fi, pt, zh; Finnish flagged as the weakest, override-covered)
+- `modes`: `["markdown", "article", "nav"]` for a structure-proven model,
+  `["markdown"]` for one that is only trusted in scoped mode
+
+The Seed-X client is untouched and announces `["segments"]` (implicitly,
+by omitting `modes`).
+
+## Importing human-made full translations
+
+The decomposition function doubles as an import path for translations
+produced outside the pipeline — e.g. an article translated with ChatGPT
+and pasted back. Today such a paste lands in the translation editor and
+is stored as one giant set of overrides; feeding it through the same
+decomposition instead writes proper `Data.trans` fragments, so later
+source edits invalidate and re-translate per chunk rather than letting
+the monolithic override silently go stale chunk by chunk. This import path is
+also the natural testbed for the decomposition and validation logic
+before any live LLM client uses it.

+  into that addition (its text is stable, user-written), as do edits and
+  deletions of added paragraphs — no original hash is ever needed for
+  translation-only content.
+
+A save often mixes several edits. `SequenceMatcher` lumps adjacent changes
+into one `replace` opcode, so regions that *removed* blocks are refined
+(`_refine_replace`): blocks pair greedily by similarity (ratio ≥ 0.5) into
+text edits, leaving unpaired source blocks as deletions — a sentence fix
+in the paragraph above a deleted paragraph no longer drags the deletion
+into the same patch. The split-paragraph grey case (one paragraph
+becomes two) deliberately stays a single `replace` patch holding both
+paragraphs: it applies whole across retranslations, rather than
+half-applying, and telling a split apart from an edit-plus-insert is
+fuzzy anyway.
+
+Every classification is best effort: a diff position whose base text no
+longer matches what the hybrid serves there (the original or the machine

+  connections and only while a page is *mostly* pending (a new article or
+  a full refresh; steady-state edit follow-up stays scoped jobs). The
+  job's key is the page's first chunk; `Job.texts` carries the full
+  original Markdown — with the page title injected as a `# {title}` line
+  at the top when the render would inject it (the body has no h1 of its
+  own), so the title translates in document context and the opening
+  paragraphs see the heading. The menu title's and parent node's existing
+  translations (from a nav job or earlier work) ride along as
+  `Job.contexts`, so the heading can match the menu while the model may
+  still adapt the in-article title to the content. The result is
+  decomposed per chunk
+  (`align_article`): non-translatable blocks (code fences, container
+  fences, raw HTML — everything `needs_translation` rejects) must appear
+  verbatim and in order and anchor the alignment; regions between anchors
+  pair positionally, a region whose block count changed stores nothing
+  (its chunks stay pending and fall back to scoped jobs), and a paired
+  block whose destinations/placeholders did not survive likewise. An
+  injected title heading's pair becomes the title fragment (heading text
+  only — never a body chunk; a demoted or merged heading simply skips it
+  and the title stays pending for a scoped title job).
+- **`nav`** — the whole navigation hierarchy at once, offered only to
+  nav-capable connections and ahead of any per-title jobs: `Job.texts`
+  carries one element, a nested Markdown list of every node title still
+  pending for the language (`- Title`, indented by depth, in menu order —
+  pages and category labels alike); the job's key is the hash of that
+  list. One round trip names the entire menu, and sibling titles
+  translate in sight of each other. The result is decomposed back into
+  per-title fragments (`align_nav`): it must be the same list item for
+  item — same count, same nesting depth at every position — or it is
+  rejected wholesale and the titles fall back to scoped title jobs; an
+  item that comes back empty, marked-up or with its destinations/
+  placeholders lost is skipped individually and likewise stays pending
+  for a scoped title job.
+
+`scripts/llm_translator.py` is the reference markdown+article+nav client
+(instruct LLMs via an OpenAI Chat Completions endpoint or ollama's native
+API); `scripts/translator.py` (Seed-X) is untouched and announces
+`["segments"]` implicitly.
+
+**Importing human-made full translations:** `align_article` doubles as an
+import path — `scripts/import_translation.py PATH LANG FILE.md` (run with
+the server stopped) decomposes a pasted whole-article translation (e.g.
+from ChatGPT) into proper `Data.trans` fragments with the same validation,
+so later source edits invalidate and re-translate per chunk rather than
+letting the translation editor's one monolithic override go stale chunk by
+chunk.

+Same channel as scripts/translator.py (Seed-X) — connect to the server's

+job modes: fragments, whole pages and the whole navigation tree cross as
+Markdown, and the server validates structure (blocks, fences, URLs,
+placeholders, list shape) before storing.
+
+The script figures out the LLM-side details itself: the endpoint shape is
+autodetected (an ollama server answers /api/version and gets its native
+/api/chat — its OpenAI-compatible /v1 ignores think:false, which hybrid
+models need off; anything else gets /v1/chat/completions — a Kimi Code
+/coding endpoint additionally has its sampling fields dropped, since it
+fixes them internally and 400s otherwise, and gets reasoning_effort
+from the config), and the
+announced language capabilities follow the model family unless overridden
+(--langs). API keys come only from the standard per-provider environment
+variables (KIMI_API_KEY, MOONSHOT_API_KEY, OPENAI_API_KEY — each sent
+only to its own provider's host — and LLM_API_KEY for any other
+OpenAI-compatible endpoint): never a config file on disk, never a CLI
+flag visible in the process list. Backend quirks (sampling, num_predict
