[Feature] Platform Bridge Integration: [Perplexity]

[vinaykolupula]

Description

Implement a new platform bridge to support [Perplexity] within the ContxtAI framework. This will allow users to manage their context, use the context thermometer, and apply highlight-to-save features directly within the [Perplexity] interface.

Target URL(s)

• Base URL: https://chat.target-platform.com
• Other relevant paths: (e.g., /c/* for chat sessions)

Technical Implementation Checklist

1. Core Bridge Setup

• Create bridge-[platform].ts in the extension/contents/bridges/ directory.
• Define the matching URL patterns in the manifest for content script injection.

2. DOM Selectors & Mapping

• Chat Container: Identify the main scrollable wrapper containing the conversation.
• Input Box: Locate the textarea or contenteditable div where users type prompts.
• Submit Button: Identify the selector to optionally trigger message sending after context injection.
• Assistant Response Blocks: Map the selectors used for rendering code blocks and raw text to support Auto-Distillation.

3. UI & Feature Integration

• Ensure the Context Thermometer mounts correctly near the input box without breaking native UI.
• Verify Highlight-to-Save context menus appear correctly when text is selected.
• Test the Context Invalidated / Fade Warning triggers appropriately on hard refreshes or chat clears.
• Verify Local Scrubber properly intercepts and masks sensitive data before it hits the platform's input area.

Known Challenges / Edge Cases for this Platform

• (Add any specific quirks here, such as: "Grok uses heavily obfuscated class names that change on every build," or "Cursor is an electron app, need to verify extension behavior in their web view.")
