No custodian holds the NSK. + +### `lez_wallet_module` + +The Rust crate (`lez-wallet-core`) compiles with `--features lez-bridge` to produce a `cdylib`/`staticlib` used by the Qt module via FFI.

Configuration runs through `meta.configure` from the owner's `logoscore` instance or any Logos app. Pre-built arm64 bundles are committed so macOS arm64 users skip the build entirely. ### Reliability -The wallet sync operation retries on `reqwest` connection errors up to a configurable retry count. Pending approvals are held in an in-memory queue with a configurable timeout (`approval_timeout_seconds`); on timeout the call is rejected and the failure is reported to the owner via the owner channel. Each skill dispatch is wrapped in a top-level `try { ... } catch (const std::exception&)` block; a failing skill returns `{"error": "..."}` without terminating the module. +Wallet sync retries on `reqwest` connection errors. Pending approvals are held with a configurable timeout; on expiry the call is rejected and the owner is notified via the owner channel. Skill dispatch is wrapped per-skill; an exception returns a JSON error and does not terminate the module or affect other running skills. ### Performance -CU costs on LEZ devnet/testnet (measured with `RISC0_DEV_MODE=0`): +Indicative CU costs on LEZ devnet with `RISC0_DEV_MODE=0`: -| Operation | Approx.

CI runs `rust-unit` and `rust-lez-bridge-check` on every push without a chain; the `integration` job brings up the chain via `docker-compose`. `ARCHITECTURE.md` covers module architecture, skill interface, spending threshold, A2A protocol binding, and security model. `LEARNING.md` documents the lez-build internals research and known gaps. ## Supporting Materials -- Demo script: `demo.sh` — 7-step end-to-end walkthrough (wallet creation, NPK, balance, sync, program deploy, program call, A2A task). -- Three-agent deployment: `docs/DEPLOYMENT.md` — storage-agent, messaging-agent, blockchain-agent with separate home dirs. -- Integration tests: `lez-wallet-module/lez-wallet-core/tests/integration_test.rs`. -- Architecture and design: `ARCHITECTURE.md`, `LEARNING.md`. -- Skill interface: `lp-0008-ai-module/scaffold/interfaces/skill.h`, `lez_wallet.h`. +- `demo.sh` -- 7-step end-to-end walkthrough (wallet creation, NPK, balance, sync, program deploy, program call, A2A task). +- `docs/DEPLOYMENT.md` -- three-agent deployment (storage-agent, messaging-agent, blockchain-agent). +- `lez-wallet-module/lez-wallet-core/tests/integration_test.rs` -- 7 integration tests. +- `ARCHITECTURE.md`, `LEARNING.md` -- design and research documentation. +- `interfaces/skill.h`, `interfaces/lez_wallet.h` -- skill and wallet interface specs. ## Terms & Conditions From ee5f0cf319b54525cbe8503376849e25f13cd6fb Mon Sep 17 00:00:00 2001 From: retraca Date: Fri, 12 Jun 2026 00:25:30 +0800 Subject: [PATCH 3/4] fix: submitted by -> retraca only --- solutions/LP-0008.md | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/solutions/LP-0008.md b/solutions/LP-0008.md index 56cc9ab..b371398 100644 --- a/solutions/LP-0008.md +++ b/solutions/LP-0008.md @@ -1,6 +1,6 @@ # Solution: LP-0008 — Autonomous AI Agent Module for Logos Core -**Submitted by:** retraca (Gonçalo Traça) +**Submitted by:** retraca ## Summary From a8a03eb2b681ddb81d6e52389fb9daa7c1f9c072 Mon Sep 17 00:00:00 2001 From: retraca Date: Fri, 12 Jun 2026 12:52:44 +0800 Subject: [PATCH 4/4] fix: update LP-0008 repo URL to lp-0008-logos-agent-module --- solutions/LP-0008.md | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/solutions/LP-0008.md b/solutions/LP-0008.md index b371398..0f9a5f9 100644 --- a/solutions/LP-0008.md +++ b/solutions/LP-0008.md @@ -12,7 +12,7 @@ Two Logos Core modules that wire a shielded LEZ wallet, Logos Messaging, Logos S ## Repository -- **Repo:** https://github.com/retraca/logos-agent-module +- **Repo:** https://github.com/retraca/lp-0008-logos-agent-module ## Approach
