Verify lemon features against a running (or disposable) instance using the cheapest sufficient tier: DIRECT (attach/RPC + control-plane WS + bus observation, no Telegram), FAKE TELEGRAM (hermetic transport via LemonChannels.Telegram.FakeAPI), or LIVE TELEGRAM (scripts/telegram_driver.py against the real bot). Use for feature verification, E2E checks, regression repros, and post-change validation.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Verify Lemon

A runbook for verifying lemon behavior end to end. Work in three tiers and
**always prefer the lowest tier that can answer the question** — most claims
about routing, sessions, runs, delivery, and transport plumbing never need
real Telegram.

| Tier | What it exercises | When |
|------|-------------------|------|
| 1 DIRECT | Router, sessions, runs, bus events, control plane, delivery funnel | Default. Anything not Telegram-wire-specific |
| 2 FAKE TELEGRAM | The real Telegram transport + outbound, hermetically (no network) | Buttons, approvals, forum topics, markdown chunking, offset/poller semantics |
| 3 LIVE TELEGRAM | Real Bot API + real chat UX | Only for wire-level/UX claims the fake cannot prove |

If `$ARGUMENTS` is provided, scope the verification session to that feature.

## Tier 1 — DIRECT (no Telegram)

### Attaching to a running instance

Discover the node name and cookie from the beam process args (or fall back to
`bin/lemon` defaults: node `lemon`, cookie `lemon_gateway_dev_cookie`, control
plane 4040, web 4080, sim UI 4090):

More than one beam can be running (production + a disposable instance you

How to install

The exact contents, by fingerprint
mdr add z80dev/lemon/verify-lemon@sha256:10ce815a4795461f

The line at the top of this page pins the label git:20260927.d6d05b6, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
