Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.03029 | $0.03029 |
| Opus 5.5 | $0.01212 | $0.01212 |
| Sonnet 5.5 | $0.00606 | $0.00606 |
| Haiku 4.5 | $0.00303 | $0.00303 |
Grade A, and why
luno CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Project
This repo is the Android app for Luno, a self-hosted SMS gateway agent. An Android phone runs a long-lived background service that sends/receives SMS and reports device health (SIM, signal, battery, delivery status) to a backend over WebSocket (REST as fallback) — any server that speaks the Luno protocol; the backend's tech stack is out of scope for this repo. Flutter is the dashboard UI only — it never talks to telephony APIs directly.
Scope decision: Android only, for now. Linux/Windows "nodes" would require external USB GSM modems and AT-command integration (no shared code with the Android telephony layer); macOS has no cellular hardware path at all. Both are explicitly out of scope until the Android app is solid. Don't add Linux/Windows/macOS platform code or dependencies without being asked.
The backend and dashboard are separate concerns (separate repositories), not part of this codebase. The node is backend-agnostic: it prescribes no server technology (Firebase, Supabase, Express, Next, Nest, … all work equally), it hardcodes no endpoints (they're runtime config set at pairing), and it depends only on the versioned wire protocol. How the backend is built is not our concern — the node's job is: receive a command, act on the radio, report what happened.
State of the repo
Progress: M1–M17 complete, plus the pairing-session system (2026-07-19).
docs/milestones.md covered the initial build-out (M1–M18)
and is kept for history; work is no longer gated on its running order.
Pairing sessions (2026-07-19). The node is now a pure pairing client: it
submits a code — typed or scanned — and renders the backend's verdict, enforcing
no expiry, usage limit, revocation or approval rule of its own, so every
enrolment policy is backend config rather than an app release. New/changed:
backend/auth/{PairingPayload,PendingEnrollment,SealedValueStore,InstallId}.kt,
a policy-driven PairingError taxonomy with forward-compatible unknown codes,
RestClient enroll v2 (nonce, installId, sessionId, reserved publicKey,
status: approved|pending|denied) plus POST /enroll/status, and QR pairing
(versioned luno://pair / JSON payload parsed natively; mobile_scanner is a
viewfinder only). See docs/pairing.md — that file is the
contract the @luno-oss/* server SDKs implement.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
