26.8.4

Features & Desktop Enhancements

• Desktop LLM Engine Parameter Parity (LlmEngine.svelte, config.svelte.ts): Added interactive slider controls for Frequency Penalty (-2.0 to 2.0), Presence Penalty (-2.0 to 2.0), and Repetition Penalty (0.0 to 2.0) to the Desktop app's LLM Engine modal, achieving full parameter parity with the Dashboard web interface.
• Desktop Settings Dropdown Clipping Fix (LlmEngine.svelte, Appearance.svelte, RiskPolicy.svelte, SecurityPrivacy.svelte, AgentProfile.svelte): Replaced overflow-hidden with overflow-visible across settings card containers so dropdown menus (such as Reasoning Effort in LLM Engine) are no longer clipped or hidden when opened near the bottom of a container.
• Unified Dropdown & Provider Icons (Dropdown.svelte, LlmIcon.svelte, Settings.tsx): Standardized dropdown component typography, alignment, and hover-states across Desktop and Dashboard, and injected visual LLM Provider Icons for enhanced visual consistency.

Security & Dependency Maintenance

• NPM Audit Vulnerability Remediation (package.json, package-lock.json): Resolved 6 moderate-to-high security vulnerabilities across core dependencies (including brace-expansion, fast-uri, hono, ip-address, postcss, and undici) by updating lockfile versions and overriding outdated tar package resolution. Registered trusted lifecycle scripts in allowScripts to maintain secure build environments.

Documentation & Ecosystem Enhancements

• Comprehensive Documentation Refresh & New Guides: Added detailed documentation for Desktop CLI (docs/cli/desktop.md), OpenSea API v2 NFT Trading Skills (docs/core/nft.md), and External MCP Servers (docs/mcp/external-servers.md). Updated core guides across architecture, CLI, chains, Etherscan, Market Oracles, ML Engine, native skills, playbooks, dashboard, privacy, security, and sandbox instructions.
• Local Version Increment: Bumped Nyxora version to v26.8.4 across all workspace packages and submodules.
