Pre-ERC: Agent Pre-Sign Risk ReportPre-ERC: Agent Pre-Sign Risk Report is a draft Ethereum Magicians proposal for an EIP-712-signed report that a risk source, identified by an ERC-8004 identity, returns about one unsigned request. It carries typed findings on tokens, approvals, addresses, payments (x402) and texts, and each finding is marked read or not read. It has no score or verdict, so the consumer applies its own policy. The author's live implementation, toll, runs on Robinhood Chain.

Poisoning 0.1% of pretraining data planted a remote code execution backdoor in Qwen3 models (0.6B, 1.7B, 4B) trained from scratch. It survived SFT, DPO and RL, and fired on about 92% of triggered prompts at 4B. At a 0.0005% poison rate (about 2,500 documents) it still fired on 1.4% of prompts.

A tweet from chasmmmmmmmmmmm says Claude Code received a new rule around 27 October 2026, delivered from Anthropic's servers under the flag "tengu_heron_brook", with no setting to disable it. The quoted rule allows original games, genre games and games from the user's own designs and assets, but forbids recreating a specific existing game, even if renamed. The post asks whether this ends game rewrites and modding, and gives no verification beyond the quoted text.

Anthropic's daily average rose from about 0.6 to 2.25 trillion tokens alongside the Opus 5.5, Sonnet 5.5 and Haiku 5.5 releases. DeepSeek leads text requests at 26.5%, and agents plus coding account for 57.7% of spending. The author notes the data describes OpenRouter only.

[Draft ERC] Swarm AI Framework β registry and charter model for purpose-bound agent swarmsEthereum Magicians discussion of a draft ERC, the Swarm AI Framework. It proposes a registry and charter model in which accounts, including autonomous agents, form, bound, run and dissolve purpose-bound swarms. A hashed on-chain SwarmSpec (roles with eligibility modules, phases, decision authorities, fallback timers) is paired with an off-chain Swarm Pack charter. Two-sided signed admission (EIP-712 / ERC-1271), challenge and substitution, and minor versus material amendments are included. Phase posture is a coordinate: executed boundary and admission, plus declared payoff, topology and coordination terms from a write-once vocabulary. This lets cooperation, competition, tenders, debate, ensembles and pipelines be expressed. It integrates with ERC-8004 agent identity and ERC-8436 decision adapters. The reference implementation is a non-upgradeable registry with five eligibility modules and a task-tender adapter. The post asks reviewers specific design questions on vocabulary, amendment classes, roster snapshots and digest kinds.

Every record remains a valid ARD entry. It adds four kinds (skill, task, agent, registry), CAIP-19/CAIP-10 anchors, JCS+SHA-256 descriptor hashes and domain claims collected as endorsements. A Solidity/Foundry reference kernel with four adapters and a Node.js resolver/gateway are included; the gateway passes the official ARD conformance CLI. The author asks for feedback on the address-as-root boundary, the envelope exclusion from the hash, same-chain-only anchors, and the proposed application/ai-task+json payload.

GitHub issue asking OpenAI to make `daemon_auto_start` opt-in in Codex CLI 0.157.0. By default, opening an interactive session starts a persistent `codex app-server --managed-daemon` that outlives the terminal. It also copies a ~374 MB platform package into ~/.codex/packages/app-server-daemon and runs a detached hourly `pid-update-loop` updater. The daemon keeps the first session's environment (proxy variables, cwd, direnv values), which the reporter ties to hook bugs #42457 and #37537. Comments confirm the problem on Windows and add the workaround (`codex features disable daemon_auto_start`, kill the updater, remove the package dir). They also note that `daemon stop` leaves the updater running and that the option is missing from the config docs. One commenter proposes an "execution receipt" (CLI version, daemon binary digest, generation, inherited-environment generation).

GitHub issue asking OpenAI to make Codex CLI's daemon_auto_start opt-in. Since 0.157.0, opening a session starts a persistent app-server daemon with no TTY. It copies a ~374 MB platform package into ~/.codex/packages, so the running binary is decoupled from the npm-installed version. A detached hourly updater restarts the backend, and the daemon pins the first session's environment variables (proxy settings, direnv-style secrets like GH_TOKEN) and cwd. The thread also reports that `daemon stop` leaves the pid-update-loop updater alive, gives a manual workaround, and proposes an "execution receipt" (client version, daemon binary digest, generation, updater state, environment generation) so clients can tell which binary and environment served a turn.

Neither involved persuading a model. The author concludes that teams should benchmark what an agent believes and also audit what it can reach, using plugin signing and update policy, least-privilege credentials per agent, and treating local MCP surfaces as attack surface.

Hybrid post-quantum stealth addresses (ERC-5564 schemeId 3)A draft ERC proposing schemeId 3 for ERC-5564 stealth addresses, combining an ML-KEM-768 encapsulation with a secp256k1 ECDH secret so that future quantum computers cannot retroactively deanonymize recipients from the public announcement log, while spending stays classical secp256k1 (and thus still quantum-vulnerable once spent).

Spending remains classical secp256k1 and unprotected once quantum computers exist; the authors flag open issues including a documented downgrade attack (recipients registered under both scheme 1 and 3 can still be paid without PQ protection), the lack of a formal ANO-CCA proof for standardized ML-KEM, and a non-NIST-approved secret combiner. It reuses the existing ERC-5564 announcer and ERC-6538 registry with no contract changes, costing 111,330 gas per payment.
