v0.5.0 — LAN mode and repeat-copy API keys

Version 0.5.0 — LAN access and repeat-copy keys

Optional LAN mode binds the selected assigned RFC1918 IPv4 address plus loopback. API key authentication is mandatory in LAN mode; exact Host matching, Origin rejection and private IPv4 client filtering remain enforced. The API tab shows detected addresses and a selectable full LAN URL. Firewall rules are not automatically changed. HTTP is unencrypted and intended for a trusted LAN or encrypted tunnel.

New API keys store an authentication hash and a Windows-user DPAPI encrypted recoverable secret. Select a key and Copy selected key after restart as often as needed. Old hash-only keys cannot be recovered; replace them and update clients. Revocation removes authentication and copy access.

Updated Pi/OpenCode helpers and DeepSeek plugin 0.2.0 accept explicitly configured private-network bridge endpoints. Stable harness session IDs remain required; local tools execute on the harness device.

Verification: 166 C# assertions passed including actual HTTP access on the PC's assigned LAN interface, required authentication, immediate revocation, host/origin/private-network policy, encrypted key persistence/retrieval and no plaintext secret in settings. Existing JavaScript helper tests, package install/backup checks and published DeepSeek runtime checks passed. Main WPF build and self-contained installer publish passed. A second physical LAN device, full firewall traversal, new installer execution and v0.5.0 live Perplexity generation remain unverified.

Local Perplexity Bridge v0.4.0 — Windows installer and harness helpers

Windows x64 installer and helper packages for Local Perplexity Bridge 0.4.0.

Downloads

• LocalPerplexityBridge-Setup-0.4.0-x64.exe: single self-contained Windows x64 installer. WebView2 Runtime is required. Existing settings/browser profiles are designed to be retained.
• LocalPerplexityBridge-All-Helpers-0.4.0.zip: all harness helper packages with instructions.
• Individual Pi/OpenCode ZIPs: extract, run Install.cmd (Node.js required), configure provider/key, and restart the harness. Existing helper files are backed up.
• DeepSeek Harness ZIP: extract to a permanent folder, install that folder through Plugins > Add plugin, then Enable now. The .tgz is the native bundle alternative. Select the plugin-owned perplexity-bridge provider in a new conversation.
• SHA256SUMS.txt: checksums for all binary/package assets.

Changes

Bounded correction for completed invalid responses, stronger tool-envelope validation, DeepSeek provider integration with stable session identity and saved-credential resolution, and a dark-by-default offline HTML handbook.

Verification boundaries

Automated API/recovery checks (152 assertions), updater checks (28 assertions), JavaScript transport/model/session suites, helper archive/install/backup tests, and published Cordis runtime checks passed. Installer build, payload integrity, and SHA-256 were verified. This final v0.4.0 installer has not received a fresh end-to-end installation/live generation test. Latest installed live evidence used bridge v0.3.4, Pro, perplexity-claude55sonnetthinking. The DeepSeek runtime tool loop passed using a harmless QA dispatcher; full Harness UI installation/built-in tool execution and full OpenCode UI execution remain unverified. Free/Max generation and live multi-account quota failover remain unverified.

This is an experimental web-session adapter with prompt-translated tools and buffered streaming. It is not the official Perplexity API. Creating this release does not configure the app updater feed.
