ergosteurandClaude Opus 5 68568ef855 fix: keep the generated config out of the published tree
A dry-run publish against the real archive caught gdl-sync.config.json
being created in the archive root: it was written into the staging
directory, and staging is rsynced wholesale. It now lives as a sibling of
staging instead, with rsync excludes as a second line of defence.

The dry run is otherwise clean -- 322 files added, 0 deleted, no new
directories -- and confirms the property that matters most: of 74 new
media files, zero duplicate media already held under a different name.
The JD2 and gallery-dl naming really do converge.

ergosteurandClaude Opus 5 3a34e4359e feat: publish fetched media by rsync, and back off from the CDN's 429s
Wires up the staging -> rsync step and replaces --archives with --index
(a listing source: local path or the viewer's API), --staging and
--publish, so the fetch host needs no copy of the archive.

rsync runs --ignore-existing with no --delete. That is a safety property
rather than an optimisation: the archive deliberately outlives Instagram,
so publishing must only ever add. It runs once at the end so a profile
that fails midway never reaches the archive half-written.

Exercised end-to-end against withaseul across all four surfaces,
publishing to a scratch directory. Seeding worked as designed (915 of 984
post items and 28 of 34 reel items already held), stories and highlights
returned no results cleanly, and the collab-reel case landed correctly:
"withaseul - reels" holds files owned by cher_ryppo, 0ct0ber19 and
official_artms, each with the owner in the filename and the crawl scope
as the directory.

The first run drew '429 Too Many Requests' from the CDN at 3M with 1-3s
sleeps and lost two videos. That is the tolerant surface complaining, so
the defaults are now 1M, 6-10s between requests, 3-6s between downloads,
sleep-429 of 120s and 8 retries. Re-running recovered both videos with
zero failures and zero 429s. Installing yt-dlp on the fetch host also
matters: without it DASH videos fall back to a progressive URL, which is
what the rate limiting hit hardest.

ergosteurandClaude Opus 5 4fee8b1dfe feat: seed gallery-dl's skip-archive so the fetcher needs no archive copy
gallery-dl skips already-held media either by file existence -- which
requires the archive mounted where it writes -- or by a sqlite
skip-archive, which requires nothing on disk. Using the latter lets the
fetch host write to local disk and rsync afterwards, avoiding tens of
thousands of small writes over CIFS and keeping a mid-sync failure from
leaving partial files on the live Resilio share.

The key is archive_prefix + archive_fmt: the literal "instagram" plus the
per-media numeric pk. Verified against a real run -- a 3-image carousel
produced 3 rows and a re-run skipped every media file.

media_id is absent from our filenames, so the DB cannot be built from
names alone, but the listing pass we already make maps every live item to
its media_id, and a file listing says which we hold. Seeding therefore
costs no extra Instagram requests and no archive content -- the listing
GET /api/archives/:name/files already serves is enough.

Measured on 0ct0ber19: 2275 live items, 2248 seeded, 27 left to fetch --
exactly the media of the two posts added since the last crawl.

The trap worth the comment it carries: posts and reels are filed under
post_shortcode, while stories and highlights use the per-item shortcode
(post_shortcode there is the containing reel's id, shared by every item).
Matching on the wrong field seeded 5 of 2275 rather than failing loudly.

ergosteurandClaude Opus 5 7b63ba6a76 docs: design a gallery-dl replacement for the JDownloader fetcher
Every claim in docs/gallery-dl.md was measured against the live site and
the archive rather than taken from documentation, because two of the
assumptions turned out to be wrong.

The safety model is the reason the config looks the way it does.
gallery-dl has two API backends: the graphql one issues a request PER
POST for every video and carousel -- the pattern that got this account
banned via Instaloader -- while the default rest one paginates listings
at 30-50 items and carries carousel_media, video_versions and
product_type inline. A 300-post profile costs ~10 requests.

Findings worth recording:

- JD2 stamped filenames in desktop LOCAL time (US Eastern), not UTC.
  Across 212 comparable posts: UTC 19 mismatches, UTC-5 10, UTC-4 zero.
  {date:Olocal/%Y-%m-%d} reproduces it; the trailing separator must be
  omitted or it lands in the strftime format.
- A profile's reels tab returns collab reels owned by OTHER accounts, so
  the directory must be forced with -D. JD2 did the same: chuuo3o and
  official_artms filenames sit inside "0ct0ber19 - reels".
- Stories and highlights need per-item {shortcode}; {post_shortcode} is
  the reel's id and is shared by every item. {date} is per-item, verified
  on a 154-item highlight with distinct times.
- gallery-dl reproduces JD2's caption .txt exactly, including writing
  nothing for an empty caption and omitting the trailing newline.
- The json sidecar needs `include`, not `fields`; `fields` silently does
  nothing in mode:json and leaks audio_user blobs. It yields `type`
  (post/reel) -- Instagram's own flag, which can retire the lone-video
  heuristic once the scanner reads it.

Naming differences between the two tools are cosmetic: EXPORT_RE already
makes the index optional and parseInt normalises zero-padding, so a mixed
archive parses identically. Tests pin that down.

ergosteurandClaude Opus 5 aac753ced9 feat: generate JDownloader crawljobs from the archives on disk
The manual flow is: paste a profile URL into JDownloader, paste the /reels URL
separately (the profile page misses some reels), set the output folder by hand,
repeat per profile. scripts/jd2-sync.ts emits one crawljob per source with the
folder already pointed at the right directory, so folder-watch picks up the
whole batch at once.

Profiles and sidecars are derived with the same grouping logic the server uses,
so output folders always match what the viewer expects to find. --download-base
maps the path for a JDownloader running on another machine (Windows paths
included), since it typically runs on a desktop against the share.

Directories that aren't Instagram profiles are skipped: an archive root also
collects tool output and exports from other services, and pointing a crawl at
those spends requests on instagram.com to be told the profile doesn't exist —
exactly the traffic worth not spending. Filtering is by username shape, plus
--skip and a .jd2ignore file for names that look like usernames but aren't.

Defaults are conservative: chunks=1, because multi-chunk ranged requests are the
one CDN-side pattern that doesn't resemble a browser, 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.

Format verified against JDownloader's own explain.txt for the folderwatch
extension, read from the daily SVN mirror rather than one of the decade-stale
GitHub copies.

Also refreshes CLAUDE.md, whose URL-state section still described the query
parameters replaced in 1.4.0, and documents the mobile feed.
