# Tooling branch

> [!CAUTION]
> ## This branch must not be pushed to GitHub
>
> `tooling` is the only branch that still contains the archive-fetching
> scripts and their docs, and those name things `main` was rewritten to
> remove:
>
> - the fetch host's **public IP** (`docs/gallery-dl.md`)
> - the browser profile the session cookie is read from
> - the NAS archive path
> - the **list of Instagram accounts being archived**
>
> On 2026-08-20 `main`'s entire history was rewritten with `git filter-repo`,
> the GitHub repo was deleted and recreated, and 22 container images were
> pruned from ghcr — all to get exactly this material out of public view.
> **One push of this branch to GitHub undoes all of it.**
>
> A second cleanup would be harder than the first: after a force-push the old
> commits stayed reachable by raw SHA, and only deleting the repository
> outright removed them.

## Remotes

| remote | what goes there |
|---|---|
| `origin` → gitea | everything: `main`, `tooling`, tags, backups |
| `github` | **`main` and the current release tag only** — it exists to run the CI/CD image build |

The other 22 release tags stay on gitea. Pushing them all to GitHub triggers
one container build per tag, because each tag carries its own workflow file.

## Guards — recreate these after a fresh clone

Neither guard is versioned, so a new clone has **no protection at all**:

```sh
git config remote.github.push refs/heads/main:refs/heads/main

cat > .git/hooks/pre-push <<'HOOK'
#!/bin/sh
remote_url="$2"
case "$remote_url" in *github.com*) ;; *) exit 0 ;; esac
while read -r _ _ remote_ref _; do
  [ -z "$remote_ref" ] && continue
  case "$remote_ref" in
    refs/heads/main|refs/tags/*) ;;
    *) echo "pre-push: refusing to push '$remote_ref' to GitHub." >&2; exit 1 ;;
  esac
done
exit 0
HOOK
chmod +x .git/hooks/pre-push
```

Decide on the **remote** ref, not the local one: a delete push sends
`(delete)` as the local ref, and an earlier version of this hook rejected
every deletion because of it.

## What lives here

| path | what it is |
|---|---|
| `scripts/gdl-sync.py` | the gallery-dl fetcher; replaced JD2 for the ARTMS profiles |
| `scripts/gdl-cron.sh` | unattended wrapper: `stories` \| `full` \| `sweep` |
| `scripts/systemd/` | the timers actually installed on the fetch host |
| `scripts/test_gdl_sync.py` | its tests |
| `scripts/jd2-sync.ts` | JDownloader `.crawljob` generator, still used elsewhere |
| `docs/gallery-dl.md` | the measurements behind every option in the fetcher — **read before changing pacing** |
| `docs/jdownloader.md` | the older JD2 flow |
| `docs/artms-instagram-accounts.txt` | the profile list passed to `--urls-file` |

## Commands

```sh
# fetch: always --dry-run first; it prints the plan and the publish step
./scripts/gdl-sync.py --index https://instaarchive.ergosteur.com \
    --staging <dir> --publish <user>@<nas>:<archives> \
    --archive-db <db> --urls-file artms_account_links.txt --abort 50 --dry-run

# crawljobs (no npm script — package.json is kept identical to main)
npx tsx scripts/jd2-sync.ts --archives <dir> --dry-run
```

Run the fetcher from the host whose public IP matches the browser the cookie
came from. `--abort 50` is the routine setting; omit it for a full sweep that
also catches edited carousels.

## Why there is no CLAUDE.md entry for any of this

`CLAUDE.md`, `README.md` and `package.json` are kept **byte-identical** to
`main` so that merging `main` into `tooling` never conflicts. The earlier
attempt put tooling notes in `CLAUDE.md` and a `jd2` script in `package.json`;
because `main` had *deleted* those lines, every merge re-applied the deletion.
Keep branch-specific documentation in this file, which `main` does not have.

## Running it by hand

Everything happens on **`mattellite`** — the fetch host whose public IP matches
the browser the cookie came from. Running it anywhere else is what
session-hijack detection looks for.

```sh
ssh mattellite
~/gdl/gdl-cron.sh full        # or: stories | sweep
```

That is the whole thing: it wipes staging, fetches, and publishes straight to
the NAS. To drive `gdl-sync.py` directly instead — always `--dry-run` first,
which prints the plan and the exact rsync that would touch the archive:

```sh
cd ~/gdl
PATH=$HOME/.local/bin:$PATH ./gdl-sync.py \
    --index    https://instaarchive.ergosteur.com \
    --staging  ~/gdl/staging-manual \
    --publish  agentapi@10.20.28.200:/volume1/rslsync/sync/Instagram-archive/archives/ \
    --archive-db ~/gdl/artms.db \
    --urls-file  ~/gdl/artms_account_links.txt \
    --abort 50 --dry-run          # swap for --execute when the plan looks right
```

`PATH` matters: `gallery-dl` is a pipx install in `~/.local/bin`, which is not
on cron's PATH and not on a non-login shell's either.

### The three modes

| mode | cadence | cost | why |
|---|---|---|---|
| `stories` | daily | ~6 requests | stories expire in 24h and **cannot be backfilled**; this is the only run that loses content if skipped |
| `full` | monthly | ~40-60 requests | every surface, `--abort 50` — stops enumerating once it reaches content already held |
| `sweep` | quarterly | ~420 requests | no abort; the **only** run that notices carousels edited after we archived them (test case 15) |

The skip-archive means an infrequent `full` costs barely more than a frequent
one — it only fetches what is new. Frequency buys freshness, not completeness,
except for stories.

## Scheduling — installed on `mattellite`

systemd **user** timers, running as `matt`, with lingering enabled so they fire
without a login session:

```sh
loginctl show-user matt --property=Linger      # Linger=yes
systemctl --user list-timers 'gdl-sync@*'
```

| unit | schedule | next fire (as installed) |
|---|---|---|
| `gdl-sync@stories.timer` | daily 09:00 | 09:36:45 — the delay is the randomisation working |
| `gdl-sync@full.timer` | 3rd of each month, 04:00 | 04:37:44 |
| `gdl-sync@sweep.timer` | 7th of Jan/Apr/Jul/Oct, 04:00 | 04:42:39 |

Unit files are version-controlled in `scripts/systemd/` and installed to
`~/.config/systemd/user/`. One templated service, `gdl-sync@.service`, takes
the mode as its instance name and runs `gdl-cron.sh %i`.

Three settings are load-bearing:

- **`RandomizedDelaySec=45m`** — a job firing at exactly 09:00 daily is
  obviously a machine, and the entire safety model is about not looking like
  one. This is why the table above shows 09:36 rather than 09:00.
- **`Persistent=true`** — catch up a run missed because the host was off.
  cron silently skips, and a skipped `stories` run is content gone for good.
- **`TimeoutStartSec=infinity`** — a sweep can run for hours at this pacing.
  The default 90s would kill it mid-fetch.

Operating them:

```sh
export XDG_RUNTIME_DIR=/run/user/$(id -u)      # needed over non-interactive ssh
systemctl --user start   gdl-sync@stories.service   # run one now
systemctl --user status  gdl-sync@full.timer
journalctl --user -u 'gdl-sync@*' -n 50
systemctl --user disable --now gdl-sync@sweep.timer  # stop one
```

`systemctl --user` fails with "Failed to connect to bus" over ssh unless
`XDG_RUNTIME_DIR` is set. Note also that **month names are not valid in
`OnCalendar`'s date field** — `Jan,Apr,Jul,Oct-07` is rejected outright, hence
`*-01,04,07,10-07`. Check any change with `systemd-analyze calendar '<expr>'`
before installing it.

### cron, if you ever prefer it

```cron
17 9  *  *  *        sleep $(shuf -i 0-2700 -n1); $HOME/gdl/gdl-cron.sh stories
43 4  3  *  *        sleep $(shuf -i 0-2700 -n1); $HOME/gdl/gdl-cron.sh full
11 4  7  1,4,7,10 *  sleep $(shuf -i 0-2700 -n1); $HOME/gdl/gdl-cron.sh sweep
```

cron runs `/bin/sh`, so `$RANDOM` does not exist — hence `shuf`. And `%` in a
crontab line means newline unless escaped, so avoid it entirely. cron has no
equivalent of `Persistent=true`.

## Verifying a run

The first unattended run is **2026-08-21, around 09:36** (09:00 plus the
randomised delay). Nothing below costs an Instagram request — every check is
against the journal, local logs, or our own viewer's API.

```sh
# 1. did it run, and did it exit 0?
ssh mattellite
export XDG_RUNTIME_DIR=/run/user/$(id -u)
systemctl --user list-timers 'gdl-sync@*'          # LAST/PASSED columns
journalctl --user -u 'gdl-sync@stories.service' --since yesterday --no-pager

# 2. what did it actually fetch? (sidecars vastly outnumber media -- count media)
ls -1t ~/gdl/logs | head -3
grep -E '^(==>|    FAILED|done;)' ~/gdl/logs/stories-*.log | tail -20
grep -ic 429 ~/gdl/logs/stories-*.log            # MUST be 0 -- see below
```

**A `429` from `scontent-*.cdninstagram.com` ends the session, it is not a
pacing knob to tune.** The warning order last time was CDN 429 → `400` on the
highlights endpoint → suspension. If a run logs one, disable the timers and
stop for the day:

```sh
systemctl --user disable --now gdl-sync@stories.timer gdl-sync@full.timer gdl-sync@sweep.timer
```

Then confirm the archive actually grew, from the workstation:

```sh
# 3. did the publish land? compare against yesterday's counts
for u in 0ct0ber19 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 '%-18s %s\n' "$u" "$n"
done
```

Counts after the 2026-08-20 run, to diff against:

| profile | files |
|---|---:|
| 0ct0ber19 | 3151 |
| official_artms | 6714 |
| cher_ryppo | 3031 |
| kimxxlip | 3019 |
| zindoriyam | 2253 |
| withaseul | 1760 |

A stories-only run adds few files and often **none** — profiles frequently have
no active story. "0 new" is a normal result, not a failure. `fileCount` in
`/api/archives` is stale by design; use the per-profile `/files` listing.

## 2026-08-21 — scraping warning, automation stopped

**Instagram flagged the account.** Not suspended: an interstitial at
`/accounts/scraping_warning/` reading *"We suspect automated behaviour on your
account"*. It was dismissed in the browser and the account is healthy — feed
loads, still signed in. **All three timers are disabled.** Do not re-enable
them without deciding the cadence question below.

How it unfolded, because each step misled in a different way:

1. **09:13** the daily timer fired, exited 0 in one second, logged
   `done; 0 step(s) failed` — and fetched nothing. Yesterday's manual run was
   18.9–19.2h earlier, just under the `--min-interval 20` floor, so all six
   sources were skipped. **A silent no-op on the one surface that cannot be
   backfilled, reported as success.**
2. **20:28** `chrome-devtools.service` was OOM-killed (5.1 GB peak, ~1w3d CPU).
   Unrelated to the above, and it does not break fetching — gallery-dl reads
   the cookie *file*, not a live browser — but it meant no browser was running
   to notice anything was wrong.
3. **23:19** a manual recovery run passed the floor (33h) and every source
   failed with `400 Bad Request` on
   `/api/v1/feed/reels_media/?reel_ids=…`. Six identical failures across six
   profiles is not a per-profile fault.
4. Cookies were **exported and checked before assuming a block**:
   `sessionid` 77 chars, printable, colon-delimited, 360 days to expiry;
   `ds_user_id` present. Decryption was fine, so the fault was server-side.
   This check costs no Instagram requests and should always come first.
5. The browser then showed the interstitial. The 400s were the challenge
   state, not a ban.

### What has to change before automation is re-enabled

- **The `--min-interval` floor silently defeats the daily job.** Any manual run
  in the preceding 20h makes the scheduled one a no-op. The floor exists to
  stop an *aborted restart* re-enumerating profiles — a minutes-to-hours
  concern — and a stories fetch is one request per profile. `stories` should
  use something like `--min-interval 8`, not 20.
- **A skipped stories run must be loud.** `0 to sync, 6 skipped` currently
  exits 0 and looks identical to success. On this surface a skip is a real
  loss, and it should be visible in the journal without reading the log.
- **Reconsider the daily cadence itself.** A job hitting story endpoints for
  six profiles every morning is the most machine-like thing here, randomised
  delay or not, and it is what was flagged. Every-few-days, or on-demand, may
  be the honest answer even though stories will be missed.
- **`chrome-devtools.service` has `Restart=no`** and died silently for three
  hours. It needs `Restart=on-failure` and probably a `MemoryMax=`, or it will
  be dead the next time the cookie needs refreshing.

### Cost of the pause

`official_artms` and `0ct0ber19` both had active stories on the evening of
2026-08-21 that will expire uncollected. That is the price of stopping, and it
is the right trade: spending requests on story endpoints minutes after
clearing a scraping warning is exactly the behaviour that was flagged.

## What changed on 2026-08-20

One session, three separate pieces of work. Recorded because the reasons are
not recoverable from the diffs.

**The sync run.** First incremental fetch in four days: 184 new media, 299
files published, 0 failures, 0 CDN 429s. 20 story items, which are the part
that could not have been recovered later. Cost about half what it would have,
because the archive DB was already seeded and the state file was primed by hand
so no probe passes ran.

**`--abort 50`.** The skip-archive suppresses *downloads*, which spends the
CDN; it does nothing about the *listing pass*, which spends `instagram.com` and
scales with how big a profile is rather than how much is new. Measured from
sidecar write times mid-run: 3 new posts took ~100s each, the other 2272 were
written in one second. Enumerating `cher_ryppo` fell from 2151 posts to 7.

**The repo split.** `main` is public and now carries none of the fetching
tooling, no host details, and no real account names — its entire history was
rewritten, the GitHub repo deleted and recreated to clear force-push residue,
and 22 container images pruned from ghcr because the server bundle had been
shipping source comments naming real accounts. This branch holds everything
that was removed. See the caution at the top.

**Automation.** mattellite got a key on the NAS, closing the last manual step,
and three systemd timers now run the sync unattended.

## Outstanding

State as of 2026-08-20, after the sync run and the repo split. Nothing here is
broken; these are decisions not yet made and cleanups not yet done.

### Fetching

- **The first unattended run has not happened yet** — 2026-08-21 ~09:36. Until
  it has, the timers are unproven in the one condition that matters: firing
  with nobody watching. Check it with "Verifying a run" above; the 20h floor
  means a manual run beforehand would make the automatic one a no-op.
- `mattellite`'s `~/.ssh/id_ed25519.pub` is in the NAS's `authorized_keys` for
  `agentapi` (added 2026-08-20, alongside the workstation's existing key), so
  the fetch host publishes straight to the archive and no `sshpass` step is
  needed. **That key is what makes the timers work** — remove it and every
  scheduled run will fetch successfully and then fail at publish.

- **5.3 GB of stale staging on `mattellite`** — `~/gdl/staging` and `~/gdl/out`
  (2.2 GB each, from the 2026-08-17 run) and `~/gdl/staging-0820` /
  `~/gdl/out-0820` (446 MB each, from 2026-08-20). Every file in all four was
  verified present in the live archive, so they are safe to delete. 46 GB free,
  so there is no urgency — but nothing will clean them up on its own.
- **No daily stories run is scheduled.** Stories expire in 24h and cannot be
  backfilled, so this is the *only* surface where waiting loses content
  permanently. `--only stories` never seeds and costs roughly six requests for
  all six profiles. When scheduling it, randomise the minute and avoid the hour
  boundary: a job firing at exactly 09:00 daily is obviously a machine.
- **`--abort 50` is opt-in and nothing uses it yet.** It is the right setting
  for routine runs — it cut a 2151-post profile to 7 enumerated posts — but it
  stops noticing **edited carousels** (test case 15), which only a full
  enumeration finds. A full-sweep cadence has not been decided; quarterly was
  suggested and never agreed.
- **The `seeded` flags in `<db>.state.json` were hand-written**, reconstructed
  from the 2026-08-17 log rather than derived from the archive DB. They assert
  "the skip-archive already knows this source". If `artms.db` is ever rebuilt,
  moved or lost, **clear the state file too** — otherwise those sources will
  never re-seed and a fetch into empty staging re-downloads everything.
- **`~/gdl/gdl-sync.py` on the fetch host is a copy, not a checkout.** It
  currently matches this branch (`96e5694e…`), but nothing keeps them in sync;
  `scp` it after any change and re-check the hash.
- The 2026-08-20 run is split across two logs — `artms-run3.log` (12 sources,
  no abort) and `artms-run4.log` (12 sources, `--abort 50`) — because it was
  stopped midway to pick up the new flag.

### Repo and infrastructure

- **The `pre-rewrite-*` branches on gitea hold the unredacted history** — real
  account names, the fetch host's IP, and the tooling, as it was before the
  rewrite. They are deliberate backups. Decide whether they expire; the
  `pre-push` hook does cover them (it allows only `main` and tags to GitHub).
- **The `pre-rewrite-full.bundle` backup is in a session scratchpad** and will
  be deleted with it. If a durable backup outside gitea is wanted, move it now.
- **Only one container image exists.** 22 versions were pruned, so rolling back
  to an older release means checking out its tag from gitea and pushing that
  tag to GitHub to rebuild it — the old images are gone, not archived.
- **CI warns that the Node 20 actions are deprecated.** `actions/checkout@v4`,
  `docker/login-action@v3`, `docker/metadata-action@v5` and
  `docker/build-push-action@v5` are being forced onto Node 24. They work today;
  bump when convenient.
- **`review-fixes`** on gitea is a stale v1.3.0-era branch, never merged,
  published only because the whole local repo was pushed. Probably deletable.
- GitHub Actions run history was lost when the repo was recreated. Cosmetic.
