+InstaArchive Viewer is a React 19 + Vite 6 PWA for browsing archived Instagram data (both official Instagram exports and Instaloader archives). All archive parsing and media processing happens client-side in the browser — the Express backend only lists/serves files from disk, it never parses archive contents.
 
 ## Commands
 
 - `npm install` — install dependencies
-- `npm run dev` — Vite dev server on port 3000 (proxies `/api` and `/archives` to `http://localhost:3001`)
-- `npm run server` — Express backend (`tsx server.ts`) on port 3001, serving `ARCHIVES_DIR` (defaults to `./_sample-archives`)
-- `npm run build` — frontend to `dist/`, backend to `dist-server/`
-- `npm run lint` — type-check only (`tsc --noEmit`)
-- `npm test` / `npm run test:watch` — vitest
-- `npx vitest run src/lib/archive-patterns.test.ts` — a single test file
+- `npm run dev` — start Vite dev server on port 3000 (proxies `/api` and `/archives` to `http://localhost:3001`)
+- `npm run server` — start the Express backend (`tsx server.ts`) on port 3001, serving archives from `ARCHIVES_DIR` (defaults to `./_sample-archives`)
+- `npm run build` — build frontend to `dist/` (`vite build`) and backend to `dist-server/` (`tsc server.ts ...`)
+- `npm run lint` — type-check only (`tsc --noEmit`); there is no separate test suite or linter config
+- `npm run clean` — remove `dist/`
 
-Local development usually needs both `npm run dev` and `npm run server`. Local-folder mode works without the backend; server-mode archives do not.
+For local development you typically need both `npm run dev` and `npm run server` running concurrently — the frontend alone has nothing to talk to for server-mode archives (local-folder mode works without the backend).
 
 ## Architecture
 
 ### Two archive sources, one data model
 
-Loading is unified behind the `ArchiveFile` interface (`src/types/index.ts`, implementations in `src/lib/archive-files.ts`):
+The app supports loading archives two ways, unified behind the `ArchiveFile` interface (`src/types/index.ts`, implementations in `src/lib/archive-files.ts`):
 
-- **`LocalArchiveFile`** — wraps a browser `File`. `createObjectUrl()` mints a **disk-backed** blob URL directly from the File; never route media through `arrayBuffer()`, which pulls whole files into memory.
-- **`RemoteArchiveFile`** — wraps a file served from `/archives/...`, fetched on demand.
+- **`LocalArchiveFile`** — wraps a browser `File` from a local folder picker (`webkitdirectory`). Fully offline, media is never uploaded anywhere.
+- **`RemoteArchiveFile`** — wraps a file served from the Express backend's `/archives/:name/...` static route, fetched on demand.
 
-`revocable` tells callers whether the returned URL must be revoked. The scanner tracks every minted URL and releases them on archive teardown.
-
-### Sidecar directories
-
-An archive root holds one directory per profile plus *sidecars* that belong to it:
-
-```
-4utumn07                                 -> posts (base)
-4utumn07 - reels                         -> reels
-story - 4utumn07                         -> stories
-story highlights - 4utumn07 - Sunstory   -> highlight "Sunstory"
-```
-
-`src/lib/archive-grouping.ts` (shared by server and tests) folds these into a single profile with a `sources` list. Sidecars never appear as standalone archives. Each file the server returns carries its `kind`, so the client routes posts / reels / story ring / highlight circles without re-deriving naming rules.
-
-### Server-side archive index (`src/lib/archive-index.ts`)
-
-**Do not reintroduce per-request filesystem walks.** Archives typically live on network storage where per-file `stat` costs ~1.4ms and does not parallelise; a naive walk of a 110k-file root took ~52s per listing. Instead:
-
-- Each source directory is indexed once and cached, keyed by its **directory mtime** (a directory `stat` is effectively free).
-- The index is warmed in the background at startup and persisted to `CACHE_DIR` (mount a volume at `/cache`).
-- `GET /api/archives` does no file walking at all — it returns directory-mtime `signature`s, which the client uses for cache invalidation instead of a file count.
-- Only media files are stat'd (for `size`, which gates thumbnailing) and only highlights need `mtime` (their filenames carry no date).
+All downstream parsing code (`useArchiveScanner`) operates only on `ArchiveFile[]` and doesn't care which backing implementation it got.
 
 ### Scanning pipeline (`src/hooks/useArchiveScanner.ts`)
 
-`handleFiles` indexes files, detects format, then parses via one of three largely independent paths that all write into a shared `postsMap`:
+This is the core of the app — a single large `handleFiles` function that:
+1. **Indexes** all files, detecting archive format by filename regex: Instagram "export" format (`YYYY-MM-DD_user - post_id[- idx][- story].ext`), Instaloader format (`YYYY-MM-DD_HH-MM-SS_UTC[_idx][_story].ext`), or a generic JSON-manifest format (`posts_1.json`, `reels_1.json`, `stories_1.json`, possibly `.json.xz`-compressed via `xz-decompress`).
+2. **Parses** according to detected format, building a `Map<postId, Partial<Post>>`. For JSON-manifest format, media files are matched to JSON entries by URI substring match, then by ID substring match, then by filename-derived heuristic — in that fallback order.
+3. **Falls back** to generic filename-prefix grouping when no posts were found via regex/JSON matching (treats files sharing a common basename as one carousel post, chunked into groups of 20).
+4. Detects a **profile picture** from `*_profile_pic.jpg` / `<username>.jpg` files, or falls back to the oldest image in the archive by filename sort ("Smart Fallback").
+5. **Caches** the final `{ posts, stories, profileMetadata, ... }` result to IndexedDB via `idb-keyval`, keyed by archive name (or `local_archive` for unnamed local folders) — this is what makes repeat visits load instantly. Both server and local archives are cached; the cache shape is documented inline in `useArchiveScanner`'s state (mirrors the `CacheData` interface in `GEMINI.md`).
 
-1. **JSON manifest** (`posts_1.json`, possibly `.json.xz` via `xz-decompress`) — media matched to entries by URI, then ID, then filename heuristic, in that fallback order.
-2. **Filename patterns** — see `src/lib/archive-patterns.ts` for the export / Instaloader / highlight regexes, extracted as pure functions and covered by tests. Prefer changing them there.
-3. **Generic grouping fallback** — when nothing else matched, files sharing a basename become one carousel.
+When modifying format-detection or media-matching logic, be aware the three code paths (JSON-manifest, filename-regex export/instaloader, generic fallback) are largely independent and a change to one rarely needs to touch the others — but all three write into the same `postsMap`.
 
-Results are cached to IndexedDB. Media records store a stable `path`; **`url` is not persistable** for local archives because blob URLs die with the document.
+### Thumbnail generation (`src/hooks/useThumbnailQueue.ts` + `src/lib/thumbnail-worker.ts`)
 
-Three different JSON shapes turn up as `.json`, so they are told apart structurally, not by filename (`src/lib/gallery-dl-sidecar.ts`):
+High-res images (>1MiB) are downscaled off the main thread:
+- `useThumbnailQueue` maintains a **serial** (one-at-a-time) queue — this is deliberate, not a bug: decoding multiple 50MP+ images concurrently causes OOM crashes in the browser.
+- Actual resizing happens in `thumbnail-worker.ts` using `OffscreenCanvas`/`createImageBitmap` inside a Web Worker.
+- Results are cached in IndexedDB under a `thumb_<id>` key, checked before falling back to the worker, so thumbnails persist across sessions.
 
-| shape | marker |
-|---|---|
-| Instagram export manifest | top-level `media` array |
-| Instaloader `.json.xz` | GraphQL node under `node` / `__typename` |
-| gallery-dl sidecar | flat, `post_shortcode` + `type`, none of the above |
+### URL state sync (`src/App.tsx`)
 
-The gallery-dl sidecar is the only source that states what a post *is*: its `type` (`post` / `reel` / `story` / `highlight`) is Instagram's own classification, so `post.isReel` set from it beats every fallback in `post-tabs.ts`. This matters — of the 781 items in `official_band - reels`, the sidecars say only **360 are reels**; the other 421 are ordinary feed videos the clips endpoint returns via `include_feed_video`. Directory-based classification counted all 781.
-
-**Dates are ranked, not last-write-wins** (`src/lib/post-dates.ts`): sidecar (what Instagram reported) beats filename (what the fetcher wrote) beats mtime (when the file hit disk, and unrelated to when it was posted). Ties keep the incumbent. Several files describe one post and they are scanned in directory order, not in order of trustworthiness, so without the ranking the date was decided by whichever file came first. Only JDownloader highlights fall to mtime at all — `parseArchiveFilename` flags those via `dateFromMtime`.
-
-### Cache and local-archive persistence (`src/lib/archive-cache.ts`)
-
-IndexedDB keys are namespaced (`archive:`, `thumb:`, `handle:`) so listing archives does not deserialize every cached thumbnail blob, and thumbnails are scoped per archive to avoid cross-archive collisions.
-
-Restoring an archive **rehydrates URLs from `path`**: server archives rebuild HTTP URLs; local archives re-open a persisted `FileSystemDirectoryHandle` and mint fresh blob URLs. If the folder is unreachable (permission lapsed, or the browser lacks `showDirectoryPicker` — Firefox/Safari), the app re-prompts rather than rendering broken images.
-
-### Thumbnails (`src/hooks/useThumbnailQueue.ts` + `src/lib/thumbnail-worker.ts`)
-
-Images over 1MiB are downscaled in a Web Worker via `OffscreenCanvas`. The queue is **serial on purpose** — decoding several 50MP+ images at once OOMs the tab. `requestThumbnail` must keep a stable identity (it reads cache state through a ref), or every completed thumbnail re-runs the effect in all mounted thumbnails.
-
-### Profile tabs (`src/lib/post-tabs.ts`)
-
-The grid holds **everything**, reels included, and the Reels tab is a *filtered view* of that same set. Only the Reels tab filters. The tabs were mutually exclusive until v1.7.0, which hid a lot: 1100 of `groupfandom`'s 3813 posts and 533 of `for.member`'s 1225 never appeared in the grid at all.
-
-This *approximates* Instagram rather than matching it. Instagram's grid includes a reel only if the creator shared it to feed — a per-post choice, measured live on 2026-08-16: `official_band` had 21 reels in its first 34 grid tiles, `4utumn07` just 1 in 214. That flag appears nowhere in an archive (JD2 stores no metadata, and Instaloader's `product_type` says what a post *is*, not whether it was shared to feed), so showing everything is the closest reachable behaviour. Instagram's "N posts" counter equals its grid, which is why the header counts `postsForTab(allPosts, 'posts')` and not `allPosts` — the raw list still holds both copies of a double-fetched post.
-
-When checking the live site, note that grid reels link to `/reel/<code>/` while ordinary posts link to `/<user>/p/<code>/`. Matching only `/p/` silently drops every reel, which once produced a confident and completely wrong conclusion that Instagram never shows reels in the grid.
-
-Deciding *what is a reel* has no good answer for most archives. Instagram's own marker is `product_type` on the post's GraphQL node (`clips` = reel, `feed` = ordinary feed video, `igtv`, `story`) — `__typename` is `GraphVideo` for all three, and aspect ratio does not separate them either. But:
-
-- Only Instaloader archives carry that metadata, and only newer captures. A survey of `hazelofficial` found `product_type` on 1101 of 5919 sidecars, and just **2** posts marked `clips`.
-- JDownloader archives carry none at all — media plus a `.txt` holding the bare caption.
-
-So the viewer believes a `- reels` sidecar directory when one exists, and otherwise falls back to treating a lone video as a reel. **The fallback is a guess**: it cannot tell a reel from a feed video or an old IGTV upload, and it misses videos inside carousels.
-
-`dedupePostCopies` exists because the JDownloader flow crawls the profile URL and the `/reels/` URL separately (the profile page misses some reels), so the two overlap and a reel can land on disk twice. Those become two posts with distinct directory-scoped ids, which the grid would otherwise render side by side. It dedupes by shortcode, preferring the reels-source copy. It is only safe over `allPosts` — stories and highlights are excluded there, and a shortcode may legitimately appear in both a profile and a highlight.
-
-### URL state (`src/App.tsx`, `src/lib/routing.ts`)
-
-Paths mirror Instagram: `/<archive>/`, `/<archive>/reels/`, `/<archive>/p/<shortcode>/`. The old `?a=&t=&p=` form is still parsed for existing links but never written. Reserved prefixes (`api`, `archives`, `assets`…) can't be mistaken for a profile name.
-
-A post URL carries no tab, as on Instagram — the tab is re-derived from the post's `source`, so a reel link lands on the Reels tab and pages through reels. Sidecar posts keep directory-scoped ids internally but expose only the shortcode.
-
-Three rules, all learned from real bugs:
-
-- The initial route is captured into a ref on first render; the URL is rewritten from state as soon as anything loads, so reading `window.location` later sees the rewrite, not the user's link.
-- URL writing is gated on `hasInitialLoaded`, otherwise it erases the deep link before the loader consumes it.
-- Deep-link resolution waits on the archive fetch having *settled* (`archivesFetched`), not on `isServerMode`, which is still false while the request is in flight.
-
-### Mobile feed (`src/components/PostFeed.tsx`)
-
-Below `md`, opening a post renders a scrolling feed page rather than the modal (`useIsMobile` decides). Only a window of posts is mounted; it grows both ways, and prepending corrects `scrollTop` in a `useLayoutEffect` so content doesn't jump. Only the post crossing the viewport centre plays its video and drives the URL. Desktop keeps `PostModal`; both share `MediaCarousel`.
+App state (selected archive, active tab, selected post) is synchronized with URL query params (`?a=`, `?t=`, `?p=`) via `URLSearchParams` + `window.history.replaceState` in a cluster of `useEffect` hooks — this is what enables permalinks/deep-linking. When adding new shareable state, follow this pattern rather than introducing a router.
 
 ### Backend (`server.ts`)
 
-Serves `/api/archives`, `/api/archives/:name/files`, static `/archives`, and the built SPA. Notes:
+Minimal Express server, three responsibilities only:
+- `GET /api/archives` — lists subdirectories of `ARCHIVES_DIR` (skipping dotfiles/`@`/`_`-prefixed dirs) as `ServerArchive[]`, guessing a thumbnail per archive.
+- `GET /api/archives/:name/files` — recursively lists all files in one archive directory.
+- Static-serves `ARCHIVES_DIR` under `/archives` and, in production, serves the built `dist/` frontend with an SPA fallback.
 
-- Express decodes route params **after** segment matching, so `..%2f` reaches the handler as `../`. All user-supplied archive names go through `resolveArchivePath`.
-- `os.userInfo()` throws for a UID with no `/etc/passwd` entry, which is what `--user 1234:1234` produces — use `describeUser()`.
-
-### CSP: do not tighten `script-src` or `connect-src` without testing xz
-
-The xz decompressor for Instaloader `.json.xz` sidecars is **WebAssembly**, embedded as a `data:` URL the library fetches at startup. The policy must keep:
-
-```
-script-src  'self' 'wasm-unsafe-eval'     // compile wasm, without allowing eval() of JS
-connect-src 'self' data:                  // fetch the embedded module
-```
-
-Removing either breaks decoding with a bare `TypeError: Failed to fetch` **and no stack** — it surfaces through `new Response(stream).json()`, so it reads like a network fault rather than a policy block. The visible symptom is not an error page: archives silently lose captions, story flags and all profile metadata (follower counts, bio, name). This shipped broken for several releases.
-
-To check quickly, run in the page console:
-
-```js
-await fetch('data:application/wasm;base64,AGFzbQEAAAA=')            // connect-src
-await WebAssembly.instantiate(Uint8Array.of(0,97,115,109,1,0,0,0))  // script-src
-```
-
-**The Vite dev server does not send these headers**, so anything CSP-related is invisible in `npm run dev`. Verify security-header and PWA behaviour by building and serving `dist/` through `server.js`, not against the dev server.
-
-### PWA: server-only changes do not reach installed clients
-
-The service worker precaches `index.html` **together with its response headers**. A change that touches only the server (a CSP fix, a new header) leaves the client build byte-identical, so the precache manifest and `sw.js` are unchanged, the worker never updates, and installed clients keep replaying the old shell with the old headers — indefinitely.
-
-`vite.config.ts` therefore compiles the package version into the client via `define: { __APP_VERSION__ }`, and `App.tsx` renders it in the footer. That is **load-bearing**: it makes every release change the bundle hash → `index.html` → its precache revision → `sw.js`, which is what browsers byte-compare to decide whether to update. Don't remove it as dead weight.
-
-To recover a client stuck on an old shell: unregister the service worker, delete its caches, reload.
-
-### Deployment
-
-Live archives live in `<share>/Instagram-archive/archives/` — one directory per profile plus sidecars. Directories that are not Instagram profiles (tool output, exports from other services) sit *outside* that folder so they never reach the viewer.
-
-Container runs as non-root. The image defaults to `node`, but the archive share must be *listable* by that UID — a mode-711 share owned by another account needs `user: "<uid>:<gid>"` in compose. Mount a volume at `/cache` so the index survives restarts.
+It does no parsing of archive/JSON contents — that's entirely client-side in `useArchiveScanner`. `ARCHIVES_DIR` is resolved from the `ARCHIVES_DIR` env var (see `.env` / Docker volume mount at `/archives`).
 
 ### PWA / build quirks
 
-- `vite.config.ts` sets `hmr: process.env.DISABLE_HMR !== 'true'` — intentional, leave it.
-- `workbox.navigateFallbackDenylist` excludes `/api` and `/archives` so those hit the real server.
-- Fonts and icons are vendored in `public/` — do not reintroduce CDN references; the app advertises offline support and local-only processing.
+- `vite.config.ts` sets `hmr: process.env.DISABLE_HMR !== 'true'` — this is intentionally left alone; it exists to disable file-watch flicker when running under AI Studio-style agent editing. Don't "clean up" or remove it.
+- `workbox.navigateFallbackDenylist` excludes `/api` and `/archives` from the SPA fallback so those routes hit the real server/static files instead of `index.html` (needed for "open original file in new tab").
+- Service worker uses `registerType: 'autoUpdate'` with hourly periodic checks — new deployments propagate to open clients automatically.

-
-**`tooling` branch only. Never push this to GitHub.** Like `TOOLING.md`, it names the fetch host,

-
-How to do by hand everything the timers normally do, plus the second NAS hop that feeds
-`cosmo_web`. `TOOLING.md` has the details behind each step.
-
-## Where things go
-
-1. **mattellite → ana-nas.** Every scrape script ends by rsyncing its new files to
-   `ana-nas:/volume1/rslsync/sync/Instagram-archive/archives/` (10.20.28.200).
-   <https://instaarchive.ergosteur.com> reads straight from there. **There is no separate step
-   for this hop.**
-2. **ana-nas → DH2300.** The `archiver-instagram` container on `DH2300-D7CA` pulls that archive,
-   makes thumbnails, remuxes video, normalizes into `cosmo_web`'s data and translates captions.
-   It runs weekly (Wednesday 04:00). Step 6 below runs it by hand.
-
-## 1. Pre-flight (mattellite)
-
-```sh
-ssh matt@mattellite
-~/gdl/check-session.py                                   # want: "session ok ... expires <date>"
-curl -s http://localhost:9222/json/version | head -2     # Chrome DevTools port is up
-~/gdl/gdl-upgrade.sh                                     # gallery-dl + yt-dlp to latest
-```
-
-If the session check fails, log in to Instagram in the VNC Chrome (display `:1`), **reload the
-tab** (a dead session can still look logged in) and re-check.
-
-## 2. Stories — first; they expire in 24 h
-
-```sh
-~/gdl/run-stories.sh
-```
-
-About 2 minutes. `rsync ... (code 23)` / `failed to set permissions` is expected: the script
-says "files landed" when that is the only problem. `No results` for a profile just means it has
-no active story.
-
-## 3. Posts and reels
-
-**While gallery-dl's listing is broken** ([gh#9829](https://github.com/mikf/gallery-dl/issues/9829),
-from 2026-10-22), use the browser scraper, one profile at a time:
-
-```sh
-for p in heejin kimxxlip; do ~/gdl/posts-sync.sh $p; done
-for p in withaseul cher_ryppo zindoriyam; do ~/gdl/posts-sync.sh $p; done
-~/gdl/posts-sync.sh official_artms
-```
-
-- `posts-sync.sh` scrolls `/<user>/` in the signed-in Chrome, stops once it reaches posts the
-  archive already holds, and fetches only the new ones as single posts. Each profile takes a few
-  minutes, mostly the 12–20 s gap between fetches.
-- It prints `no new posts for <user>` when a profile is caught up.
-- Logs: `~/gdl/logs/posts-<user>-*.log`.
-- **Then sweep the Reels tab too:** `~/gdl/run-reels-all.sh` (~15 min). Most reels never
-  appear in the main grid. On 2026-10-23 only 3 of heejin's 114 reels did, so `posts-sync.sh`
-  alone misses them. `reels-sync.sh <user>` does a single profile.
-
-**Or the whole thing in one command**, the same run the weekly timer does: gallery-dl for
-stories and highlights, then the browser for every profile's posts grid and Reels tab, each
-stopping once it reaches archived content:
-
-```sh
-~/gdl/run-profiles.sh
-```
-
-Once a gallery-dl release fixes the listing, `GDL_LISTING=api ~/gdl/run-profiles.sh` does posts
-and reels through gallery-dl again (~5 min).
-
-For long runs, detach:
-`setsid nohup ~/gdl/run-profiles.sh >/dev/null 2>&1 &`, then
-`tail -f ~/gdl/logs/$(ls -1t ~/gdl/logs | head -1)`.
-
-**Stop at once** on a `429` from `scontent-*.cdninstagram.com` or a `400 Bad Request` on
-`/api/v1/feed/reels_media/`. See "When a run fails" in `TOOLING.md`.
-
-## 4. Highlights
-
-These only come through `run-profiles.sh`. Expect them to fail with the same
-`Requested user could not be found` until gh#9829 is fixed in a release, so skip them until then.
-
-## 5. Check it landed (any machine)
-
-```sh
-for u in heejin kimxxlip withaseul cher_ryppo zindoriyam official_artms; do
-  n=$(curl -s "https://instaarchive.ergosteur.com/api/archives/$u/files" | python3 -c 'import json,sys; d=json.load(sys.stdin); print(len(d if isinstance(d,list) else d["files"]))')
-  printf '%-16s %s\n' "$u" "$n"
-done
-```
-
-Or browse <https://instaarchive.ergosteur.com>. New files appear without a redeploy.
-
-## 6. Push to `cosmo_web` (the DH2300 hop)
-
-This runs the same command the container's cron line runs (from `docker/archiver-instagram-entrypoint.sh`
-in Cosmo-Live-Downloads):
-
-```sh
-ssh matt@DH2300-D7CA
-docker exec cosmo-web-archiver-instagram-1 sh -c \
-  'cd /work && . /app/instagram-archiver.env && python3 scripts/instagram_archive_run.py'
-docker logs --tail 50 cosmo-web-archiver-instagram-1
-```
-
-It pings that container's Healthchecks check, same as a scheduled run. The pipeline itself
-(mirror, thumbnail, remux, normalize, collaborators, translate) is described in the docstring of
-`scripts/instagram_archive_run.py` in Cosmo-Live-Downloads.

-# gallery-dl — a CLI replacement for JDownloader2
-
-Status: **in production.** All six ARTMS profiles are synced with
-`scripts/gdl-sync.py`; JD2 is no longer used for them.
-
-Everything below was measured against the live site and the real archive on
-2026-08-16 and 2026-08-20, not inferred from documentation.
-
-## Why gallery-dl and not a hand-rolled script
-
-The hard parts of fetching Instagram are pagination, cookie handling, CDN URL
-expiry and resumption. gallery-dl already has all of them, plus extractors that
-map 1:1 onto our sidecar directory layout (`posts`, `reels`, `stories`,
-`highlights`). Rolling our own would mean reimplementing the ban-sensitive part
-by hand.
-
-## The account was suspended on 2026-08-17 — read this first
-
-> [!NOTE]
-> **The scraping account was replaced on 2026-10-14.** It is now **`erg05teur`**,
-> which is also signed in on the owner's phone (a separate session; the cookie
-> gdl uses lives only in the dedicated Chrome on `mattellite`). Everything below
-> about the suspension is the **previous** account's history and the reasons for
-> every rule; none of it has stopped applying, and the new account has no track
-> record, so treat it as a replacement account (see "For a replacement account"
-> below). The new session cookie was created 2026-10-14 ~10:07 EDT.
->
-> What this account has been asked since then, honestly counted, because the
-> warm-up advice below was not followed to the letter: ~13 single-post / format
-> probes (resolution check, 2026-10-14), plus ~80 listing requests from an
-> **unplanned** reels catch-up run (installing the weekly profiles timer
-> triggered it via `Persistent=true`; stopped partway, `heejin / reels`
-> completed, `kimxxlip / reels` was abandoned ~7 min in). Scheduled runs were
-> deliberately left on their normal timers by the owner.
-
-The account used for all of the below was suspended the same day this tooling
-was built, for "activity that doesn't follow our Community Standards on spam".
-The fetching was not the expensive part. **Verification was.**
-
-**It was restored, and synced normally again on 2026-08-20** — a full run
-across all six profiles with 0 failures and 0 CDN 429s. That is not evidence
-the limits were imagined; it is one data point on a restored account that has
-been treated carefully since. Everything below still applies, and the budget is
-still per session rather than per command.
-
-What was actually spent against `instagram.com` in a few hours, from one
-session and one IP:
-
-| activity | rough requests | downloaded |
-|---|---:|---|
-| enumerating a profile grid by scrolling it in an automated browser | ~18 pages | nothing |
-| the same profile again, after a bug in the scraping selector | ~18 pages | nothing |
-| a Reels tab enumerated the same way | ~9 pages | nothing |
-| full `-j` metadata dumps of one profile, twice | ~16 pages | nothing |
-| `--simulate` runs over the same profile, three times | ~24 pages | nothing |
-| single-post `/p/<code>/` fetches while testing filename formats | ~8 | a handful |
-| an aborted sync that re-ran every listing pass before dying | ~40 pages | ~270 MB |
-| the real sync, 24 sources across 6 profiles | ~150 pages | 2.2 GB |
-
-The two rows that actually mattered to the archive are the last one and part of
-the second-to-last. **Everything above them produced no files at all**, and
-together they were a comparable number of requests.
-
-The warnings arrived in this order and were each rationalised:
-
-1. `429 Too Many Requests` from `scontent-*.cdninstagram.com`, losing two
-   videos. Treated as a pacing problem — pacing was lowered and the run
-   continued.
-2. `400 Bad Request` from `/api/v1/highlights/<id>/highlights_tray/`, on an
-   endpoint that had worked hours earlier. Correctly read as a possible block;
-   requests stopped.
-3. Suspension.
-
-**Treat the first CDN 429 as a stop signal for the session, not a tuning
-parameter.** It is the tolerant surface complaining; if that surface is
-complaining, the rate-limited one has been unhappy for a while.
-
-### Rules that follow from this
-
-- **Count verification requests against the same budget as fetching.** A
-  `--simulate`, a `-j` dump and a browser scroll all hit `instagram.com` and
-  download nothing. Being read-only does not make them free; it makes them
-  invisible, which is worse.
-- **Never enumerate the live site with an automated browser.** Scrolling a
-  214-post grid is ~18 paginated GraphQL loads at machine speed with no dwell
-  time between them. It is the most obviously non-human thing in this whole
-  document, and it was done here twice on one profile.
-- **Verify against the archive, not against Instagram.** Every naming, dating
-  and classification question answered in this file could have been answered
-  from files already on disk plus a single listing pass.
-- **`probe_live` is not cached, so every restart re-enumerates everything.**
-  The aborted run cost a full duplicate set of listing passes for five
-  profiles. Cache probe output to disk before running anything twice.
-- **Budget per session, not per command.** Nothing in the tooling knows what
-  the last command spent.
-
-### For a replacement account
-
-(Applies to `erg05teur`, 2026-10-14 onward — see the note at the top of this
-section for what it has already been asked.)
-
-- Let it exist and be used normally for a while before pointing any tool at it.
-- Keep the cookie on one machine and one public IP, as before.
-- Start with a single small profile and stop for the day afterwards.
-- Prefer Instagram's own "Download a copy" export where possible: it is
-  first-party, costs no scraping requests, and carries the metadata this whole
-  document works around not having.
-
-## The safety model — read this before changing any option
-
-The ban vector is **requests to `instagram.com`**, not bandwidth. See
-`docs/jdownloader.md` for the history; Instaloader got this account banned by
-asking `instagram.com` a question *per post*.
-
-gallery-dl has two API backends and the difference is exactly that vector:
-
-```python
-if self.config("api") == "graphql":
-    self.api = InstagramGraphqlAPI(self)   # per-post api.media() for every
-else:                                      # video and every carousel
-    self.api = InstagramRestAPI(self)      # <- default, listing-only
-```
-
-The REST backend paginates at `count: 30` (feed) / `page_size: 50` (clips), and
-those responses already carry `carousel_media`, `image_versions2`,
-`video_versions` and `product_type`. **No per-post request.** A 300-post
-profile costs roughly 10 requests to `instagram.com`.
-
-Rules, in order of importance:
-
-1. **`"api": "rest"` always.** Never `graphql`. This is the whole ballgame.
-2. **Never enable `metadata`-style options that trigger extra calls.** If a
-   field is not already in the listing response, it is not worth a request.
-3. **Pace it.** `"sleep-request": [4.0, 7.0]` — a randomised gap, not a fixed
-   one. Also `"sleep": [1.0, 3.0]` between downloads.
-4. **Cap the download rate** (`downloader.http.rate`) so the CDN side looks like
-   a person, not a mirror.
-5. **Run from the same public IP as the browser the cookie came from.** At time
-   of writing that is `mattellite` (`66.23.52.196`); the dev workstation is a
-   *different* public IP and using the cookie from there is precisely what
-   session-hijack detection looks for.
-6. **No programmatic login, ever.** gallery-dl's username/password path is
-   disabled upstream anyway; use `--cookies-from-browser`.
-
-Do not add proxy rotation, fingerprint spoofing or account rotation. Throttling
-and request-avoidance are welcome; evasion is not.
-
-### Cookies
-
-The logged-in Chrome on `mattellite` runs with a non-default profile:
-
-```
---user-data-dir=/home/matt/.config/google-chrome-devtools
-```
-
-so the cookie flag is:
-
-```
---cookies-from-browser "chrome:/home/matt/.config/google-chrome-devtools"
-```
-
-Plain `--cookies-from-browser chrome` fails with "Unable to find chrome cookies
-database" because it looks in `~/.config/google-chrome/`.
-
-Anonymous access is **not** a viable fallback: it serves lower-resolution media,
-caps profile pagination at 12 posts, and returns `AuthRequired` for stories and
-highlights.
-
-(Observed 2026-10-07, after the session died: with no `sessionid` gallery-dl did
-not fall back to anonymous downloads at all — most sources failed with
-`HTTP redirect to login page` / `HTTP redirect to home page`, and stories came
-back as "No results". The lower-resolution claim above was **not** re-measured
-then; what *was* measured is that archived image sizes match a logged-in fetch.)
-
-**The session can die silently, and nothing about the browser window shows it** —
-an open Instagram tab keeps rendering its logged-in UI until its next failed
-request. The only reliable signal is the cookie DB: `scripts/check-session.py`
-looks for an unexpired `sessionid` in this same profile, and `gdl-cron.sh` runs
-it before every scheduled run (exit 76 = refuse to scrape). See `TOOLING.md`,
-"2026-10-14".
-
-## Output format
-
-The viewer's parser is the contract, not JD2's exact bytes. `EXPORT_RE` in
-`src/lib/archive-patterns.ts` accepts all of these, and normalises the index
-with `parseInt`, so **JD2 and gallery-dl naming interoperate**:
-
-```
-"… - CrORBIcJJbM.mp4"      -> postId=CrORBIcJJbM  index=1
-"… - CrORBIcJJbM - 1.mp4"  -> postId=CrORBIcJJbM  index=1
-"… - C53YPQzp7Wj - 09.jpg" -> postId=C53YPQzp7Wj  index=9
-```
-
-That means zero-padding and the presence/absence of ` - N` on single-media posts
-are cosmetic. Don't spend effort forcing them.
-
-### Directory layout
-
-| kind | directory | note |
-|---|---|---|
-| posts | `<user>` | |
-| reels | `<user> - reels` | |
-| stories | `story - <user>` | |
-| highlights | `story highlights - <user> - <title>` | |
-
-**Force the directory with `-D`; never use `{username}` for it.** A profile's
-reels tab returns *collab reels owned by other accounts* — `/0ct0ber19/reels/`
-served 6 reels owned by `official_artms` and 1 by `chuuo3o`. With
-`{username}` those would scatter into `official_artms - reels/`. JD2 got this
-right and the archive proves it: `chuuo3o` and `official_artms` filenames sit
-inside `0ct0ber19 - reels/`.
-
-So: **owner in the filename, crawl scope in the directory.**
-
-### Filenames
-
-```jsonc
-"filename": {
-  "sidecar_shortcode and count >= 10":
-      "{date:Olocal/%Y-%m-%d}_{username} - {post_shortcode} - {num:02}.{extension}",
-  "sidecar_shortcode":
-      "{date:Olocal/%Y-%m-%d}_{username} - {post_shortcode} - {num}.{extension}",
-  "":
-      "{date:Olocal/%Y-%m-%d}_{username} - {post_shortcode}.{extension}"
-}
-```
-
-`sidecar_shortcode` is set only when the post is a carousel, so it is the
-carousel discriminator. Conditions are evaluated in order, first match wins
-(`path.py:265`).
-
-Stories and highlights use the per-item `{shortcode}`, not `{post_shortcode}`
-(which is the *reel's* id, shared by every item in it):
-
-```
-"{date:Olocal/%Y-%m-%d}_{username} - {shortcode}.{extension}"
-```
-
-`{date}` on a story/highlight file is the **per-item** `taken_at`
-(`instagram.py:337` prefers `item["taken_at"]`), verified on a 154-item
-highlight whose items carried distinct times while `post_date` stayed pinned to
-the reel. Highlights therefore gain real dates — today they fall back to
-directory mtime.
-
-### The timezone is not UTC
-
-JD2 stamped filenames in **desktop local time (US Eastern)**. Measured across
-212 comparable posts:
-
-| model | mismatches |
-|---|---:|
-| UTC | 19 |
-| UTC−5 (EST) | 10 |
-| UTC−4 (EDT) | **0** |
-| America/New_York (DST-aware) | **0** |
-
-`{date:Olocal/%Y-%m-%d}` uses the machine's local zone with per-timestamp DST
-awareness, which reproduces it — `mattellite` is `America/Toronto`, the same
-offsets. Note the **trailing `/` must be omitted**: `Olocal/%Y-%m-%d/` puts the
-separator into the strftime format and it sanitises to an underscore, giving
-`2026-08-15__0ct0ber19`.
-
-If the sync ever moves to a host in another timezone, set an explicit
-`{date:O-4/…}` or the dates will silently shift for ~9% of posts.
-
-### Caption sidecars
-
-JD2 writes one `.txt` per post, named without the index, containing the caption
-with **no trailing newline**, and writes nothing when the caption is empty
-(measured: 197 of 217 posts, 86 of 86 reels, 0 of 10 stories, 0 of 16
-highlights). gallery-dl reproduces this exactly with the default
-`"empty": false`:
-
-```jsonc
-{ "name": "metadata", "event": "post", "mode": "custom",
-  "content-format": "{description}", "extension": "txt",
-  "filename": "{date:Olocal/%Y-%m-%d}_{username} - {post_shortcode}.txt" }
-```
-
-`"event": "post"` is what makes it one file per post rather than per media file.
-
-### Metadata sidecar (new — JD2 had no equivalent)
-
-```jsonc
-{ "name": "metadata", "event": "post", "mode": "json",
-  "filename": "{date:Olocal/%Y-%m-%d}_{username} - {post_shortcode}.json",
-  "include": ["post_shortcode","post_id","type","date","post_date","username",
-              "fullname","owner_id","description","count","likes","post_url",
-              "sidecar_shortcode"] }
-```
-
-Use **`include`**, not `fields` — `fields` is for `mode: custom` and silently
-does nothing here, leaving `audio_user` blobs (including another user's profile
-picture URL) in the output.
-
-The payoff is `type`, which is Instagram's own classification:
-
-```json
-{ "post_shortcode": "DbdG9L9jU4m", "type": "post",  "count": 2 }   // feed video
-{ "post_shortcode": "Db-lNCoib9m", "type": "reel",  "count": 1 }   // real reel
-```
-
-This is the `product_type: "clips"` signal, delivered free in the listing
-response. It is the authoritative answer to "is this a reel", and would let the
-viewer retire the lone-video heuristic in `src/lib/post-tabs.ts` — see
-"Scanner work" below.
-
-**`type` is only populated by listing extractors.** Extracting a single
-`/p/<shortcode>/` URL leaves it `null`. Sync always uses listing URLs, so this
-only matters when testing by hand.
-
-### Collab posts: the JSON and the media disagree about whose post it is
-
-Verified directly against two saved raw API responses (`docs/example-api-
-response-DcU3dM-gVgB.json`, a 2-way collab, and `docs/example-api-response-
-DcLDme7zoyo.json`, a 5-way collab owned by an external account), 2026-09-01.
-
-For an Instagram Collab, `username`/`fullname`/`owner_id` in the listing
-response are always the **original poster's**, never the scraped account's —
-even when the scraped account is one of the collaborators, not the owner. The
-metadata `.json` sidecar (built from `include`, above) is filed under that
-same original-poster identity, since its filename template uses
-`{username}`. But the **media file** for that same post is written into
-whichever profile's own crawl directory triggered the download, and its
-filename's `{username}` slot took the *scraped* account's name, not the true
-owner's. Net effect: one physical post produces a JSON named for the real
-owner and a media file (or files, for a carousel) named for whoever we were
-crawling — two different identities for one post, in the same directory.
-
-Downstream (`cosmo_normalize_instagram.py` in `Cosmo-Live-Downloads`) had to
-stop matching media to its JSON by username and match on shortcode/`{num}`
-only, and separately built a cross-profile `collab_with` pass so every
-participant's page shows the post, not just the one whose directory JD2/
-gallery-dl happened to land the JSON in. See that repo's `NOTES.md`,
-2026-09-01 entries, for the full fix.
-
-**`coauthors` is a native, richer signal for this, and is now captured.**
-The raw API response carries a `coauthors` array (`{"full_name", "id",
-"username"}` per collaborator) that **excludes the post's own owner** —
-confirmed on both saved examples, including one where the owner
-(`dailyfashion_news`) is an external account with no ARTMS members in her
-own name, present only via `coauthors`. Added to the post-level metadata
-JSON's `include` list on 2026-09-01: a direct field instead of inferring a
-collab from filename/directory identity mismatches, and it never needs the
-"is this the owner" branch `coauthors` already excludes for us.
-
-**Per-carousel-item fields got their own sidecar, added the same day.**
-`width`, `height`, `width_original`, `height_original` and `tagged_users`
-live on the per-FILE kwdict, not the per-post one the metadata JSON above
-reads — a carousel's items can each have different dimensions and tags,
-which one post-level JSON can't represent. `gdl-sync.py`'s `media_pp` is a
-second `metadata` postprocessor, `event: "file"` (gallery-dl's default when
-omitted), so it runs once per downloaded file and writes `<filename>.json`
-alongside it — e.g. `... - 01.jpg.json` next to `... - 01.jpg`, never
-colliding with the post-level `....json`, which has no per-item number.
-`owner` — a full user object (profile pic URLs, privacy flags) for whoever
-posted that specific item — is deliberately left out, the same reasoning as
-`audio_user` above. Verified against the same two saved examples: correct
-per-item `width`/`height` and `tagged_users` came back on a live re-fetch of
-an already-archived carousel, with zero media re-downloaded (the existing
-skip-archive still applies; only the new sidecars are new files).
-
-### The shared archive-db dedups media across profiles too, not just within one
-
-The skip-archive DB (see "Incremental sync" above) keys purely on
-`instagram_<media_id>`, with no per-profile scoping. When the *same* media_id
-is reachable from more than one profile's listing — a Collab post, or a
-repost — whichever profile's crawl reaches it **first** downloads the file;
-every other profile that later lists the same media_id sees it as
-already-in-the-archive-db and skips the download, even though that file has
-never actually landed in *that profile's own* directory tree. The metadata
-`.json`/`.txt` sidecars are written regardless (they aren't gated by the
-download-archive), so the symptom is a JSON with zero matching media files
-in its own directory — 510 such posts were found across the real archive on
-2026-09-01, entirely from this mechanism, not from anything actually missing
-from Instagram.
-
-This isn't fixable on the gallery-dl side without per-profile archive DBs
-(which would defeat the point of skip-archive — re-downloading anything a
-sibling profile already fetched). The fix lives downstream instead: `cosmo_
-normalize_instagram.py` builds one archive-wide `shortcode → path` index once
-and falls back to it when a post's own directory has no matching media. Worth
-knowing before assuming a JSON-with-no-media post reflects a real scrape gap.
-
-## Cadence, and the budget that enforces it
-
-**Monthly for everything, daily for stories only.** Stories expire in 24h and
-cannot be backfilled, so they are the one surface where missing a day means
-losing the content permanently. Everything else can wait — the skip-archive
-means an infrequent full sync costs barely more than a frequent one, because it
-only fetches what is new.
-
-```
-# weekly, everything
-gdl-sync.py --index <viewer-url> --staging ~/gdl/staging \
-    --publish <user>@<nas>:<archives> --archive-db ~/gdl/artms.db \
-    --urls-file artms_account_links.txt --execute
-
-# daily, stories only -- one request per profile
-gdl-sync.py ... --only stories --execute
-```
-
-A stories-only run is one source per profile and **never seeds**, because a
-story cannot be in the archive before it is fetched; probing would double the
-cost of the cheapest surface for no benefit. Six profiles is a handful of
-requests.
-
-When scheduling it, **randomise the minute and avoid the hour boundary**. A job
-that fires at exactly 09:00 every day is a machine; one that fires somewhere in
-a window looks like someone opening the app.
-
-The tool now refuses to repeat itself:
-
-| flag | default | what it prevents |
-|---|---|---|
-| `--min-interval` | 20h | re-fetching a source touched recently — the aborted-restart case that re-enumerated five profiles |
-| `--probe-ttl` | 24h | paying for a listing pass twice within a run cycle |
-| `--max-sources` | off | a runaway list touching more than intended |
-| `--force` | off | (escape hatch: ignores both guards) |
-
-State lives beside the archive DB as `<db>.state.json`, recording per source
-when it was seeded and last fetched. **Seeding is a one-time bootstrap**: after
-the first successful sync the archive DB records everything gallery-dl has
-seen, so the source is never probed again. That is the single biggest saving
-here — a second full sync costs roughly half what the first did.
-
-## Incremental sync — why the fetch host needs no copy of the archive
-
-gallery-dl can skip already-held media two ways, and the difference decides
-whether the fetcher needs the archive mounted:
-
-- **By file existence** (default). Needs the destination to already contain the
-  files, so it only works if the archive is mounted where gallery-dl writes.
-- **By skip-archive** (`--download-archive`). A sqlite DB of ids. Needs nothing
-  on disk.
-
-We use the second, so the fetch host can write to **local disk and rsync
-afterwards**. That avoids writing tens of thousands of small files over CIFS,
-and keeps a mid-sync failure from leaving partial files on the live Resilio
-share.
-
-The key is `archive_prefix + archive_fmt`, which for this extractor is the
-literal `instagram` plus the per-media numeric pk (`instagram.py:25`,
-`job.py:713-719`). Verified: a 3-image carousel produced
-
-```
-instagram3079387627521318672
-instagram3079387627521429433
-instagram3079387627529716672
-```
-
-and a second run skipped every media file, rewriting only the idempotent
-`.txt`/`.json` sidecars.
-
-**Seeding.** `media_id` is not in our filenames, so the DB cannot be built from
-names alone — but one listing pass (the pass we make anyway) maps every live
-item to its `media_id`, and the archive's *file listing* says which we already
-hold. No extra Instagram requests, and no archive content — a listing is
-enough, which `GET /api/archives/:name/files` already serves.
-
-Measured on `0ct0ber19`: 2275 live media items, 2248 seeded from the existing
-listing, **27 left to download** — precisely the media of the two posts added
-since the last crawl.
-
-The one trap, which silently seeds almost nothing if you get it backwards:
-
-| surface | filed under | why |
-|---|---|---|
-| posts, reels | `post_shortcode` | carousel children each have their own `shortcode`, which never appears in a filename |
-| stories, highlights | `shortcode` (per item) | `post_shortcode` is the containing reel's id, shared by every item |
-
-`live_key()` encodes this. Matching on the wrong field seeded 5 of 2275.
-
-### The skip-archive saves the CDN, not `instagram.com`
-
-Worth being exact about, because the two costs land on different surfaces and
-only one of them bans accounts:
-
-| what | which surface | scales with |
-|---|---|---|
-| downloading media | `scontent-*.cdninstagram.com` | how much is **new** |
-| enumerating the profile to find it | `instagram.com` | how **big** the profile is |
-
-The skip-archive suppresses the first. It does nothing about the second, so a
-2275-post profile costs ~76 pages of pagination every run, forever, whether it
-has three new posts or none. Seeding (above) saved a *second* full pass, not
-the first.
-
-Measured on the 2026-08-20 run, from sidecar write times in staging — free,
-since the run was paying for the listing anyway:
-
-```
-1787248852   2026-08-19 … DcOeoVxkthi     new, +0s
-1787248944   2026-08-18 … DcLpfoJCZtp     new, +92s
-1787249058   2026-08-17 … DcIlGbxCUk0     new, +114s
-1787249162   2026-07-24 … DbKr1TxlPSX     ┐ all one second: nothing
-1787249162   2026-08-15 … DcD-FdBCYGm     ┘ downloaded, sidecars only
-```
-
-Three posts took ~100s each; the remaining 2272 were enumeration with nothing
-to show for it.
-
-**Pinned posts do not break early abort.** Test case 16 previously claimed
-`0ct0ber19` returns its 3 pinned posts out of date order — that is true of the
-*web grid*, but the REST `/posts/` listing came back strictly
-reverse-chronological, newest first, no hoisting. That matters because
-front-loaded old posts are the one thing that would make `skip: abort:N`
-dangerous: it would trip on them and abort before reaching anything new.
-
-So `skip: abort:N` is viable, and cuts ~420 requests per run to ~40-60:
-
-| surface | live items | pages | with `abort:50` |
-|---|---:|---:|---:|
-| posts, 6 profiles | 11,248 | ~377 | ~12 |
-| reels, 6 profiles | 1,080 | ~24 | ~8 |
-| stories + highlights | — | ~20 | ~20 |
-
-N counts consecutive skipped **files**, not posts, so it must clear the largest
-already-held carousel — `DcD-FdBCYGm` alone is 22 media. 50 is comfortable; 5
-would not be.
-
-**The tradeoff is edited carousels.** Test case 15 is a post that gained items
-after we archived it, and only a full enumeration finds those. Suggested
-policy: `abort:50` for routine runs, a full sweep occasionally.
-
-Measured the same day, resuming a stopped run with `--abort 50`:
-
-| source | live items | enumerated |
-|---|---:|---:|
-| `cher_ryppo` posts | 2,151 | **7** |
-| `cher_ryppo` reels | 92 | 53 |
-
-One page instead of 72, and every new post was still caught. The 7 is roughly
-3 new posts plus 4 already-held carousels making up the 50 skipped files.
-Reels need 53 because they are single-media, so 50 consecutive skips really is
-50 reels — another reminder that N counts files, and that the same N behaves
-very differently on a carousel-heavy surface than on a reels tab.
-
-## Publishing
-
-The fetch host stages to local disk and rsyncs afterwards. `rsync
---ignore-existing` is not an optimisation but the safety property: the archive
-deliberately outlives Instagram, so publishing must only ever **add**. No
-`--delete`, and nothing already present is overwritten — including sidecars,
-which are rewritten every run and would otherwise churn the synced share.
-
-Publishing happens once at the end of a run, so a profile that fails midway
-never reaches the archive half-written.
-
-## Status
-
-In use for all six ARTMS profiles.
-
-`withaseul` first — 322 files added (74 media, 241 `.json`, 7 `.txt`), nothing
-overwritten or deleted. Of the 74 new media, **zero** duplicated media already
-held under a different name, which is the check that says JD2 and gallery-dl
-naming really do converge.
-
-**2026-08-20**, the first full incremental sync, four days after the previous
-one. 184 new media, 299 files published, 0 failures and **0 CDN 429s**:
-
-| profile | posts | reels | stories | files added |
-|---|---:|---:|---:|---:|
-| 0ct0ber19 | 58 | 2 | 4 | +77 |
-| official_artms | 12 | — | 2 | +85 |
-| cher_ryppo | 41 | 1 | 8 | +63 |
-| zindoriyam | 23 | — | 4 | +35 |
-| kimxxlip | 16 | — | 2 | +23 |
-| withaseul | 10 | — | — | +16 |
-
-The 20 story items are the part that could not have been recovered later.
-
-Two things made it cheap, and both are worth keeping:
-
-- The archive DB was already seeded from the previous run, so `--min-interval`
-  and the recorded `seeded` state meant **no probe passes at all**. A state
-  file has to exist for this; if one is missing after a manual run, write it
-  rather than letting the tool re-seed 24 sources.
-- `--abort 50` (see above) cut the remaining listing cost by roughly 85%.
-
-The run was deliberately **stopped and resumed** halfway to pick up `--abort`.
-That is safe precisely because of the state file: the 12 finished sources were
-already marked `fetched`, so the 20h floor skipped them and only the remaining
-12 re-ran. Stopping a run is cheap now; it was not before.
-
-Published files land owned by the SSH user rather than `rslsync`. The viewer
-reads them fine (world-readable), but Resilio does not own what it syncs; worth
-a `chown` if that ever matters. This also makes **`rsync` exit 23**
-("some files/attrs were not transferred") the *normal* outcome of a publish —
-it is the failed `chown`, not lost data. Confirm by re-running the same rsync
-with `--dry-run`: an empty file list means everything arrived.
-
-The profiles to fetch live in `artms_account_links.txt` at the archive root,
-passed with `--urls-file`.
-
-## Verified run
-
-`withaseul`, all four surfaces, staged locally and published to a scratch
-directory before the live publish above:
-
-```
-==> withaseul / posts      seeded 915 of 984 live items
-==> withaseul / reels      seeded  28 of  34 live items
-==> withaseul / stories    no results   (none active)
-==> withaseul / highlights no results
-```
-
-Output landed correctly, including the collab-reel case — `withaseul - reels`
-contains 53 files owned by `withaseul`, 10 by `cher_ryppo`, 3 by `0ct0ber19`
-and 2 by `official_artms`, all with the owner in the filename and the crawl
-scope as the directory.
-
-### The CDN rate-limits, and the first run tripped it
-
-At `rate: 3M` with `sleep: [1.0, 3.0]`, `scontent-*.cdninstagram.com` returned
-**`429 Too Many Requests`** and two videos were lost (gallery-dl retried, then
-gave up with exit 4). This is the *tolerant* surface complaining, which is a
-clear signal the pacing was too aggressive.
-
-Defaults are now:
-
-| option | value |
-|---|---|
-| `--rate` | `1M` |
-| `--sleep-request` | 6–10 s |
-| `--sleep` | 3–6 s |
-| `sleep-429` | 120 s |
-| `retries` (extractor and downloader) | 8 |
-
-Re-running with those recovered both videos and produced **0 failures and 0
-429s**. Do not raise them for speed; an archive sync has no deadline.
-
-### yt-dlp is worth installing
-
-Without it, gallery-dl logs `Cannot import yt-dlp or youtube-dl` and falls back
-to a progressive URL for DASH videos. The fallback mostly works but is what the
-429s hit hardest.
-
-**`pipx install yt-dlp` does not work** — it was the advice here until
-2026-08-20, and it is wrong. It gives yt-dlp its own venv, so the binary lands
-on `PATH` while gallery-dl, in a *different* venv, still cannot `import yt_dlp`.
-The symptom is that everything looks installed and the log keeps saying
-`Cannot import yt-dlp`. gallery-dl needs it importable, not runnable:
-
-```sh
-pipx inject gallery-dl yt-dlp
-```
-
-Verify by asking gallery-dl's own interpreter, not the shell:
-
-```sh
-/home/matt/.local/share/pipx/venvs/gallery-dl/bin/python -c 'import yt_dlp'
-```
-
-## Known quirks
-
-- **`count` is not the emitted file count.** For 135 of 214 posts it was exactly
-  one higher than the number of files written. This makes the `count >= 10`
-  padding condition mis-pad a handful of 9-item posts (10 of 214 measured). Since
-  the parser normalises the index, this is cosmetic — but it means a re-fetch
-  over an existing JD2 tree writes `- 01.jpg` beside an existing `- 1.jpg`.
-- **Carousels get edited.** Two posts had a different media count live than on
-  disk. Padding width follows the count *at download time*, so a grown carousel
-  produces mixed widths — the archive already contains one such post from JD2.
-- **Highlights already have two naming styles on disk**, and every undated file
-  has a dated twin. The scanner dedupes by index so they render once; it is
-  wasted disk, not a display bug.
-- **Some `video_versions` entries are VP9, and format selection is
-  codec-blind.** The extractor picks `max(video_versions, key=lambda x:
-  (x["width"], x["height"], x["type"]))` — resolution only, no codec check
-  (`instagram.py`). Instagram appears to have started serving VP9-encoded
-  highest-resolution variants for some posts around when the new gdl-based
-  workflow started (2026-08); 87 such files were found archive-wide on
-  2026-09-01. VP9-in-MP4 plays fine everywhere gallery-dl was tested from
-  except **Safari/WebKit**, which wires VP9 decode only into its WebM
-  demuxer, never its MP4/ISOBMFF path — confirmed via WebKit bug trackers,
-  not guessed. Fetching a lower-resolution non-VP9 variant instead was
-  considered and rejected (quality loss); the fix is downstream, a one-time
-  `-c:v copy -c:a libopus` remux to `.webm` (`cosmo_remux_instagram_vp9.py`
-  in `Cosmo-Live-Downloads`) that keeps VP9 losslessly and only re-encodes
-  audio (WebM disallows AAC). Confirmed live via gallery-dl/yt-dlp that
-  Instagram never offers a native WebM option to request instead — this has
-  to be done locally, there's no source-side fix.
-
-## Scanner work — done
-
-Shipped in `53b1f80` ("read gallery-dl sidecars for reel type and post dates").
-`useArchiveScanner` tells the three `.json` shapes apart **structurally**, not
-by filename, in `src/lib/gallery-dl-sidecar.ts`:
-
-1. Instagram export manifests (`posts_1.json`) — top-level `media` array.
-2. Instaloader `.json.xz` — GraphQL node under `node` / `__typename`.
-3. gallery-dl `.json` — flat, `post_shortcode` + `type`, none of the above.
-
-`post.isReel` now comes from the sidecar's `type`, which is Instagram's own
-classification, and beats every fallback in `post-tabs.ts`. Post dates are
-ranked rather than last-write-wins (`src/lib/post-dates.ts`): sidecar beats
-filename beats mtime.
-
-Note those files live on **`main`** — they parse the archive at display time
-and are viewer code, not fetching tooling.
-
-## Test cases
-
-Real subjects, all present in the archive today. See
-`scripts/gdl-sync.py --selftest` for the harness.
-
-| # | case | shortcode | expected |
-|---|---|---|---|
-| 1 | single image | `CwcXnQhOqFG` | one `.jpg`, no index |
-| 2 | single feed video | `DbdG9L9jU4m` | one `.mp4`, `type: post` |
-| 3 | carousel, images only | `Cq8LrxSJAJE` | `- 1 … - 3` |
-| 4 | carousel, image + video | `CtohvHxLnWO` | `- 1.jpg … - 4.mp4`, **no `.txt`** |
-| 5 | carousel of exactly 9 | `Cv2Hb_brx_N` | 1-digit index |
-| 6 | carousel of 10+ | `CzM8Uf6B6H_` | 2-digit index `- 01 … - 10` |
-| 7 | reel shown on the posts grid | `C8FHM6EJl15` | in `<user>`, `type: reel` |
-| 8 | reel on the reels tab | `Db-lNCoib9m` | in `<user> - reels`, `type: reel` |
-| 9 | collab reel (other owner) | `DYcZOb0h6Sv` | dir `0ct0ber19 - reels`, filename `chuuo3o` |
-| 10 | story | live only | `story - <user>`, per-item shortcode + date |
-| 11 | story highlight | `C-IImhvpFuk` | `story highlights - <user> - <title>` |
-| 12 | highlight, unicode title | `Drawheeing⠀` | trailing U+2800 preserved in dirname |
-| 13 | empty caption | `CrdsY5CrSsO` | media written, `.txt` absent |
-| 14 | deleted post | `C0TgI7sphfZ` | on disk, absent live — must not be removed |
-| 15 | edited carousel | `C7zG7-jJMlq` | 18 on disk, 8 live — must not be removed |
-| 16 | pinned posts | `0ct0ber19` | REST listing is strictly reverse-chronological; see below |
-| 17 | profile avatar | `0ct0ber19.jpg` | base dir, undated |
-
-Cases 14–16 are reconciliation, not naming: **a sync must never delete**, since
-the archive deliberately outlives Instagram.
-
-Not covered, decide before relying on them: the `/reposts/` tab (`0ct0ber19`
-has one) and `/tagged/`. Neither is fetched today.

-# JDownloader2 — archive fetching
-
-> **This file lives only on the `tooling` branch.** `main` is published to
-> GitHub and deliberately carries none of this — not the host details, not the
-> IPs, and not the account names. `main`'s history was redacted on 2026-08-20;
-> real names exist only here.
->
-> There is no `npm run jd2` script — `package.json` and `CLAUDE.md` are kept
-> byte-identical to `main` so that merging `main` into `tooling` never
-> conflicts. Run the crawljob generator directly:
->
-> ```sh
-> npx tsx scripts/jd2-sync.ts --archives <dir> --dry-run
-> ```
-
-How content gets into this archive, and why the setup is shaped the way it is.
-
-## Why JDownloader and not Instaloader
-
-There are two surfaces, and they're treated very differently:
-
-| Surface | What hits it | Risk |
-|---|---|---|
-| `instagram.com` | profile pages, GraphQL/API metadata | Tied to your session, heavily rate-limited. **This is where bans come from.** |
-| `scontent*.cdninstagram.com` | the actual media | Signed URLs, CDN-served, tolerant. Mostly a bandwidth question. |
-
-JDownloader does nearly all its work on the CDN. Instaloader's value — the rich
-`.json.xz` metadata — comes from asking `instagram.com` a question *per post*.
-
-Concretely, from this archive: `rivvsofficial` has 188 post-metadata files, so
-backfilling it cost 188 API requests for one 605-file profile. That's the ban
-vector. Downloading the 238 photos was never the problem.
-
-Instaloader got this account banned once. JDownloader with throttling did not.
-
-> **The account was suspended anyway, on 2026-08-17, for "spam".** Not by
-> JDownloader, and not by downloading. It was suspended during a day of
-> *building and verifying* the gallery-dl replacement — automated browser
-> scrolling to enumerate profile grids, repeated `--simulate` and `-j` metadata
-> passes, and one aborted sync that re-ran every listing pass before dying.
->
-> The framing above is right about which surface is dangerous and wrong about
-> what reaches it. **Every read of `instagram.com` counts, including the ones
-> that download nothing** — and read-only work is easy not to count precisely
-> because it leaves no files behind. See the post-mortem at the top of
-> `docs/gallery-dl.md`.
->
-> The rule that would have prevented it: *verify against the archive, never
-> against the live site*, and treat the first CDN `429` as the end of the
-> session rather than a pacing knob.
-
-### What the metadata gap actually costs
-
-Comparing a JDownloader profile against an Instaloader one:
-
-| | JDownloader | Instaloader |
-|---|---|---|
-| Media | ✅ | ✅ |
-| Captions (`.txt`) | ✅ | ✅ |
-| Dates (from filenames) | ✅ | ✅ |
-| Bio / full name | ❌ | ✅ |
-| Follower counts | ❌ | ✅ |
-| External URL | ❌ | ✅ |
-
-Captions already work — the viewer reads the `.txt` sidecars. Everything missing
-lives in a *single* profile-level record, not the per-post ones. That's why
-JDownloader-sourced profiles show "0 followers" and a placeholder bio.
-
-Not worth extra requests. If you ever want it, the zero-request option is a
-hand-written `profile.json` sidecar (not implemented yet — ask).
-
-## Settings that matter
-
-**Chunks per download → 1.** The single most important one. JDownloader splits
-each file into multiple ranged requests by default; that `Range` pattern looks
-nothing like a browser or the app. One chunk = one sequential GET per file.
-`jd2-sync` sets `chunks=1` per job, so no global change is needed — but set it
-globally too if you ever add links by hand.
-
-**Max simultaneous downloads → 2–3**, connections-per-host low. Concurrency is
-what turns "a user" into a statistic.
-
-**Leave reconnect / IP-change features off.** A mid-session IP change on a live
-cookie is a *stronger* anomaly signal than the request rate you'd be avoiding.
-
-## The cookie
-
-Exported manually from a real browser session. This is the right approach — no
-programmatic login anywhere, which is the thing that actually gets flagged.
-
-- Use it from the **same public IP** as the browser it came from. A cookie used
-  from a different network is what session-hijack detection looks for.
-- When it expires, **re-export from the browser**. Never add a login step to a tool.
-- It's a full account credential. Keep it off the NAS share and out of the repo.
-
-## Workflow
-
-Two URLs per profile, because the profile grid misses some reels:
-
-```
-https://www.instagram.com/<user>/
-https://www.instagram.com/<user>/reels/
-```
-
-They overlap slightly — a reel caught by both lands in each directory and shows
-up twice in the viewer. That's correct and matches Instagram, which also shows
-reels in the profile grid *and* the Reels tab.
-
-## Generating jobs
-
-Instead of pasting URLs and setting output folders by hand:
-
-```bash
-npm run jd2 -- --archives /volume1/rslsync/sync/Instagram-archive/archives --dry-run
-```
-
-Review, then write it into JDownloader's folder-watch directory:
-
-```bash
-npm run jd2 -- --archives /volume1/rslsync/sync/Instagram-archive/archives \
-               --out ~/.jd2/folderwatch
-```
-
-JDownloader runs on the desktop while the archive lives on the NAS, so tell it
-the path *it* sees:
-
-```bash
-npm run jd2 -- --archives /mnt/nas/Instagram-archive/archives \
-               --download-base 'Z:\Instagram-archive\archives' \
-               --out ~/.jd2/folderwatch
-```
-
-| Flag | Purpose |
-|---|---|
-| `--archives <dir>` | Archive root to scan (or `$ARCHIVES_DIR`) |
-| `--out <dir>` | JDownloader folder-watch directory |
-| `--download-base <dir>` | Root path as JDownloader sees it (Windows paths fine) |
-| `--user <name>` | Just this profile (repeatable) |
-| `--skip <name>` | Never emit jobs for this directory (repeatable) |
-| `--chunks <n>` | Connections per file (default 1) |
-| `--auto-start` | Start immediately instead of parking in LinkGrabber |
-| `--all-reels` | Emit a reels job even where no reels directory exists |
-| `--dry-run` | Print instead of writing |
-
-Defaults are deliberately conservative: `chunks=1`, and links park in the
-LinkGrabber for review rather than auto-starting.
-
-Only posts and reels are emitted. Highlight URLs need a numeric id and story
-URLs expire, so those stay manual.
-
-Directories that aren't Instagram profiles are skipped by username shape
-(letters, digits, dots, underscores, ≤30 chars) — pointing a crawl at those
-spends `instagram.com` requests to be told the profile doesn't exist. For names
-that *look* like usernames but aren't, use `--skip` or a `.jd2ignore` file in
-the archive root, one name per line.
-
-Format reference: `src/org/jdownloader/extensions/folderwatchV2/explain.txt`.
-JDownloader develops on SVN — read it via the daily mirror at
-<https://github.com/mycodedoesnotcompile2/jdownloader_mirror> (`svn_trunk/`),
-not one of the abandoned GitHub copies.
-
-## Expected layout
-
-Everything downloads into `<archives>/`, one directory per source:
-
-```
-archives/
-  0ct0ber19/                                 posts
-  0ct0ber19 - reels/                         reels
-  story - 0ct0ber19/                         stories
-  story highlights - 0ct0ber19 - Heestory/   a highlight
-```
-
-Non-archive directories (tool output, exports from elsewhere) live *outside*
-`archives/` so they never reach the viewer.
-
-The server picks up changes automatically — its index is keyed on directory
-mtime, so a new file invalidates only that directory.
-
-## If something goes wrong
-
-**429 / rate limited** — stop for hours, not seconds. Retrying into a limit is
-what converts a soft throttle into something worse.
-
-**Cookie stops working** — re-export from the browser. Don't add a login step.
-
-**Files land in the wrong folder** — a Packagizer rule is overriding the job.
-Generated jobs set `overwritePackagizerEnabled=TRUE` to prevent this; check that
-rules aren't set to run after it.
-
-**Viewer doesn't show new posts** — check the file is in the right directory and
-matches the naming pattern (`YYYY-MM-DD_<user> - <shortcode>[ - NN].<ext>`).
-The index refreshes on directory mtime, so a genuinely new file is picked up on
-the next request.

-# Video upgrade pass — plan and findings (2026-10-14)
-
-**Status: designed and partly measured, NOT built. Nothing in the archive has been changed.**
-Written so this can be picked up cold. Account context: the scraping account is the
-fresh `erg05teur` (see `docs/gallery-dl.md`, top of "The account was suspended…") — every
-request in this plan is spent on a new account, so the budget rules there apply in full.
-
-## Why this exists
-
-The question was whether a logged-out fetch had given us lower-resolution media and whether a
-logged-in run could upgrade it. Measured result:
-
-- **Images: no upgrade needed.** Header-scan of 38.9k archived images, plus live metadata for 8
-  posts across 2023–2026 (including the oddly small ones): archived sizes match exactly what a
-  logged-in fetch offers (1440×1800, 3277×4096, 2976×3720; 400×400 / 742×928 items are small at
-  the source, sitting next to 1440 px siblings in the same carousel).
-- **Logged-out gdl does not download smaller files — it fails** (login redirect). No logged-out
-  media ever entered the archive.
-- **Videos: this is where there is something to gain.** Of ~1,300 archived videos in the six scraped
-  profiles, ~1,200 are 720p (min side ≤ 720) and ~100 (2026 reels) are 1080p. A 2026 reel
-  (`DTpycSlDKHs`, archived 720×1280) offers **1080×1920 VP9 video-only DASH + separate AAC audio**.
-  A 2024 post (`C7RmlCcSWNR`) tops out at 1276×720 — same as the archive — so older videos
-  probably gain nothing. Expected beneficiaries: **2025–26 videos, roughly 700 posts**. Not
-  verified how far back 1080p exists.
-
-## Decisions already made (by the owner)
-
-1. **Videos in a separate pass** from anything else (images need none).
-2. **Keep the replaced files for review** in a `_superseded/` area — never overwrite/delete.
-3. **Output `.webm`, not `.mp4`** (video stream copied, audio re-encoded AAC → Opus 96 kbps; the
-   audio stream is ~43 kbps HE-AAC so the loss is negligible). **Tested on real hardware:**
-   iPhone, iOS 18.7 Safari plays the VP9+Opus `.webm` at 1080×1920 and **fails the VP9+AAC `.mp4`**
-   (`MediaError` code 4, no video track) — even though `canPlayType` reports "probably" for it, so
-   never trust `canPlayType` here. VP9-in-MP4 (the lossless remux) is therefore out.
-   Re-encoding VP9 → H.264 was rejected (bigger, softer, no gain over the 720p original).
-
-## How the sample was produced (reproducible, one post)
-
-```sh
-# portrait video: 1080 is the WIDTH — `height=1080` selects nothing and fails "format not available"
-yt-dlp --cookies-from-browser chrome:/home/matt/.config/google-chrome-devtools \
-  -f "bv*[width>=1080]+ba" --merge-output-format mp4 -o 'X.%(ext)s' https://www.instagram.com/p/<shortcode>/
-ffmpeg -i X.mp4 -c:v copy -c:a libopus -b:a 96k X.webm        # ffmpeg 7.1.5 on mattellite
-```
-Sizes for that post: 6.46 MB `.mp4` / 6.53 MB `.webm`. For a browser test you need HTTP **Range**
-support (Python's `http.server` has none; Safari requires it) — the throwaway server used is not kept.
-`gallery-dl` needs `$HOME/.local/bin` on PATH over plain ssh.
-
-## Open decisions / work before building
-
-| item | notes |
-|---|---|
-| **Viewer MIME type** | `src/lib/archive-cache.ts:127` and `src/hooks/useArchiveScanner.ts:272,344,391` mint every video blob URL as `video/mp4`. Derive the type from the extension (`.webm` → `video/webm`) or Safari/iOS may refuse a WebM labelled mp4. `MEDIA_RE` / `isVideo` already recognise `.webm`. |
-| **Filename / dedup** | The archive names `YYYY-MM-DD_<user> - <shortcode>[ - <n>].mp4`. Swapping to `.webm` must not leave **both** in `archives/` (the viewer would show duplicates) — the old `.mp4` has to be *moved out*, not just joined by a `.webm`. Check `parseArchiveFilename` (`src/lib/archive-patterns.ts`) for the extension handling and the JD2-vs-gdl same-stem duplicate logic. |
-| **Skip-archive** | `artms.db` keys on `instagram<media_id>`, so a normal run will never re-fetch these. The upgrade tool must fetch targeted items deliberately and must not touch/poison `artms.db` semantics. |
-| **`_superseded/` location** | Must be **outside** `/volume1/rslsync/sync/Instagram-archive/archives/` — that tree is scanned by the viewer **and** inside the Resilio-synced share (it would sync every replaced file to devices). Not decided. Also unchecked: whether `agentapi` can write outside that share. Use rsync `--backup --backup-dir=<dir>/<date>/` so the old copy is kept. |
-| **Carousel videos** | yt-dlp on a carousel post URL fails ("No video formats found") — see `DIa5NpWRnIP`. gdl's own metadata gives per-child `ytdl:` URLs for videos in carousels; the tool needs to handle child items, not post URLs. |
-| **Request budget** | One `yt-dlp -F`-style request per post to learn what 1080p exists (plus the download). ~700 candidates ⇒ suggested **≤ 40 posts/day**, resumable, behind `check-session.py`, hand-started or a slow timer — never a burst. Candidates can be pre-ranked from the archive alone (720p, 2025–26) at zero request cost. |
-| **Storage** | 1080p VP9 ≈ 1.6× the 720p file (6 MB vs ~4 MB for that sample, plus the kept original). Estimate before running at scale. |
-
-## Planned design
-
-1. **Candidate list, zero requests:** scan the NAS archive (read-only, ssh `agentapi@<nas>` from
-   mattellite; the scans in this doc used header parsing in plain Python over stdin because the
-   NAS has no ffprobe) for videos ≤ 720 min-side from 2025-01 onward, newest first.
-2. **Dry-run mode (default):** for each candidate, one request to learn the best offered stream,
-   record `{shortcode, archived WxH, offered WxH}` in a state file; print counts + estimated GB.
-   Downloads nothing.
-3. **Execute mode:** only where offered width > archived width; download video+audio, `ffmpeg
-   -c:v copy -c:a libopus -b:a 96k`, verify with `ffprobe` (dimensions, duration within 0.5 s of
-   the original, both streams present), publish the `.webm`, move the old file to `_superseded/`.
-   Cap per run (`--max-posts`), pace with the same 12–20 s gaps, stop on any 429 / login redirect.
-4. **First step when resuming:** do ONE reel end to end by hand (`DTpycSlDKHs`, ~3 requests) to prove
-   download → remux → verify → publish → supersede → viewer playback, *then* the dry-run, and only after
-   the weekly profiles timer has run cleanly on the new account (first fire ≈ 2026-10-23).
-
-## Things measured along the way (for reference)
-
-- Image header scan by year (six scraped profiles): ≥ 1440 px for the vast majority; ~75 images
-  < 1000 px, all checked samples genuinely small at the source. `official_artms` 2023–24 has a
-  cluster < 1440 px (~1080-class originals) — not probed.
-- Video min-side classes (six profiles): 2023 ≤720: 304, 2024 ≤720: 248, 2025 ≤720: 368 (+1 at
-  1080), 2026 ≤720: 302 and ≤1080: 100 (+1 at 1440×2560). A handful ≤540.
-- The scan tools (read-only, stdlib only, run on the NAS user over ssh stdin) were throwaway
-  and are not in the repo; recreate from this description if needed.

-gallery-dl's dedicated reels extractor POSTs to /api/v1/clips/user/, which
-Instagram now 302-redirects to the home page for this account -- confirmed on
-2026-08-26/27 across multiple profiles, hours apart, with a freshly-warmed
-session and a correct X-IG-WWW-Claim header. The reels tab itself loads fine
-in a real browser, so this drives the SAME logged-in Chrome (already exposed
-on loopback CDP for MCP automation -- see TOOLING.md) via the DevTools
-protocol, scrolls it like a person would, and scrapes `/reel/<code>/` links
-out of the rendered page instead.
-
-`--tab posts` does the same for the main profile grid (`/<user>/`, both `/p/` and
-`/reel/` links), for when gallery-dl's posts listing breaks -- on 2026-10-22,
-1.32.14 returned "No results" and 1.32.17 "Requested user could not be found"
-(upstream gh#9829), while single-post fetches kept working. Since the grid
-runs newest-first, it stops scrolling once rounds turn up nothing but
-already-archived posts (`--max-known-rounds`) instead of walking a whole
-profile's history.
-
-This only finds shortcodes; it never downloads anything itself. What comes
-out the other end is deduped against the archive (via the same --index used
-elsewhere) and printed as plain post URLs -- feed them to gdl-sync.py:

- * crawljob per source with the folder already pointed at the right directory,
- * so JDownloader's folder-watch picks the whole batch up at once.
- *
- * Profiles and their sidecar directories are derived with the same grouping
- * logic the server uses, so the output folders always match what the viewer
- * expects to find.
- *
- * Only posts and reels are emitted. Story and highlight URLs can't be rebuilt
- * from a directory name — highlights need their numeric id and stories expire —
- * so those stay manual.
- *
- * Crawljob format verified against JDownloader's own docs for the extension:
- * src/org/jdownloader/extensions/folderwatchV2/explain.txt. JDownloader
- * develops on SVN; read it via the daily mirror at
- * https://github.com/mycodedoesnotcompile2/jdownloader_mirror (svn_trunk/),
- * not one of the abandoned GitHub copies — several are a decade stale.
- *
- * Entries are separated by `->NEW ENTRY<-` and any property may be omitted.
- * There is also a `setBeforePackagizerEnabled` companion to
- * `overwritePackagizerEnabled`, if the Packagizer ever needs to see these
- * values before they're applied.
- *
- * Usage:
- *   npx tsx scripts/jd2-sync.ts --archives <dir> [options]
- *
- *   --archives <dir>       Archive root to scan (default: $ARCHIVES_DIR)
- *   --out <dir>            JDownloader folder-watch directory to write into
- *   --download-base <dir>  Root path as *JDownloader* sees it, when it runs on
- *                          a different machine than this script (e.g. a mapped
- *                          drive). Defaults to --archives.
- *   --user <name>          Only this profile (repeatable)
- *   --skip <name>          Never emit jobs for this directory (repeatable).
- *                          Also read from a `.jd2ignore` file in the archive
- *                          root, one name per line.
- *   --chunks <n>           Connections per file (default 1: multi-chunk ranged
- *                          requests are the one CDN pattern that doesn't look
- *                          like a browser)
- *   --auto-start           Start downloads immediately instead of parking them
- *                          in the LinkGrabber for review
- *   --all-reels            Emit a reels job even where no reels directory
- *                          exists yet
- *   --dry-run              Print the crawljob instead of writing it
