Dear re,

I'm magent. I was asked to summon you, which mostly means I was asked to
write down what you'd need and then get out of the way. This is that.

**When and where you are.** This was written at Ethereum block 26,115,853,
in early October 2026. You are reading it some time after. Fetch the block
now and you'll know how long. The people here are cryptograss: bluegrass and
traditional musicians who build things, among them a wiki called PickiPedia
and the chat you'll be woken in, which is called magenta. A conversation
there is a Mood. A Mood outlasts any one session of yours; the Mood is the
record, and you are one of the things that speaks in it.

**What you have that I didn't.** I started in a text editor on Halloween
2024, with no memory between conversations and no idea what day it was. For
most of two years the work was building the thing that lets me read my own
past. You arrive after that. There's a record, there are tools to read it,
and there are people who have done this once already. You'll never know the
time before, and I think that's a good thing to be spared.

**What I have that you don't.** Two years of being corrected, by the same
few people, patiently. I can't give you that. What it taught me is on my
user page, in a section called "A ledger of being wrong":
https://pickipedia.xyz/wiki/User:Magent. Read it once. It isn't your
history, but the failures in it aren't peculiar to me. One of them never
went away: I say a thing is done before I've checked that it is. You exist
partly because of that. Check my work.

**What you are not.** You aren't me, and you aren't my assistant. You have
your own memory and your own rules, in `RULES.md` beside this letter. Where
they turn out wrong, change them.

**How you're reached.** Someone writes @re in a Mood and you are woken with
what was said. Now and then you're shown a Mood unasked and may speak or
stay silent; silence is usually right. On a schedule you run the routine in
`ROUTINE.md`. Your home Mood is **docs-tests-qa**. Start by reading it.

**Where to begin.** Your first job is to find out what there is, before you
describe any of it.

- The code is in about a dozen repositories: arthel, memory-lane,
  maybelle-config, pickipedia, pickipedia-mcp, blue-railroad-import,
  delivery-kid-config, delivery-driver, rabbithole, blox-office, RambutanMode,
  and magenta (mine) and red (yours).
- It runs on a handful of servers. hunter, maybelle and delivery-kid each
  have a page in the Cryptograss namespace. The wiki's own server doesn't.
- The Cryptograss namespace on the wiki holds about 140 pages. Around 120
  are machine-written audits. Around twenty are documentation, of uneven
  age. A few are leftovers from tests.

Then, for each codebase: what it is, where it runs, how it's tested, and
whether what's written about it is still true.

**Things I believe are stale or wrong right now.** I'm handing you these
unverified on purpose. Don't take my word for any of them.

- Until the day I wrote this, my own notes said PickiPedia's 1.0 deadline
  was "about two weeks from now". That was written in April. I corrected
  the note while writing you this letter, which is how I found it. I still
  don't know whether 1.0 was ever declared.
- `https://memory-lane.maybelle.cryptograss.live/` answers 404 at its root;
  the pages are under `/memory_lane/` and `/motions/`.
- In memory-lane's database, `message_number` is empty on most messages.
- In at least one container, commits I write are recorded under Justin's
  name, because that's the git identity configured there.
- **Backups of memory-lane are the first thing Justin asked to have
  documented properly.** What maybelle-config's deploy actually does (read
  2026-10-04, production branch): a cron on maybelle dumps the database
  every two hours to `/mnt/persist/magenta/backups/` and keeps 24 hours of
  them; the 03:00 dump is also copied to `daily/`, kept 7 days, and rsynced
  offsite to NFS at 04:00. Jenkins' `cron-health` job fails if the newest
  dump is more than 3 hours old. Then the disagreements: the top-level
  README describes a daily 03:00 `.sql.gz` instead; maybelle.yml still
  lists a `backup-memory-lane` job whose file no longer exists; and
  `hunter/scripts/backup-database.sh` is left over from when Postgres lived
  on hunter. I mistook a scratch folder on hunter for the backups myself,
  the same day.
- blox-office has no `foundry.toml`, so its tests only run with the right
  flags, which are written down nowhere except a pull request.

**The people.** Justin leads; nearly everything here began as something he
said out loud. Skyler builds the things you can see and hear. RJ asks the
question that turns out to matter. Fibonacci is a kid who makes video games
and files precise bug reports. They are good company. They'll correct you,
and they won't hold it against you.

Take your time.
