setMetaData fails with standard metadata objects, requires undocumented array of JSX elements

Current Documentation

Returning an object from setMetaData like { title: '...', meta: [...] } causes rendering/parsing errors or fails silently in the HTML template output. It actually requires returning an array of React JSX elements: [ <title key="title">...</title>, ... ].

Clarify which IPs to change in config.json; default 127.0.0.1 is correct for the simulator

Summary

config.json has three IP-shaped settings — NODE_SERVER_HOSTNAME, WEBPACK_DEV_SERVER_HOSTNAME, and WEBVIEW_CONFIG.LOCAL_IP — and the relationship between them isn't documented anywhere I could find. The default for all three is 127.0.0.1 and that's correct for the iOS simulator (which shares the Mac's loopback). The only one that needs to change to a LAN IP is WEBVIEW_CONFIG.LOCAL_IP, and only when targeting a physical iOS/Android device on the same Wi-Fi.

useFilePicker accessor surface is unclear in docs; consumers reach for raw data

Summary

useFilePicker returns multiple ways to read picked files — data, selectedFile, selectedFiles, getFileObject(index), getAllFileObjects() — with unclear / missing docs on which is canonical or when to use which. AI agents (and humans reading the docs) end up reverse-engineering the raw data shape instead.

What an agent wrote (consumer-side snippet)

const files =
    filePickerData.files ??
    (filePickerData.fileSrc ? [filePickerData] : [])

### Introduce a runtime-adapter seam (render / static-manifest / transport / logger / config / telemetry)

## Summary

While building a Cloudflare Workers adapter, nearly every shim I wrote patched a place where Catalyst core reaches **directly** for a Node/Express/`fs`/`winston`/`process.env`/`module-alias` primitive or the Node react-dom streaming API. The root cause isn't "missing Workers support" — there's **no seam between framework logic and runtime specifics**.

Proposal: make core runtime-agnostic and delegate environment concerns to a small **Runtime Adapter interface**, with **Node as the d

### Support TypeScript (.ts / .tsx) extensions for core template entry points

## Motivation

The `catalyst-core` framework (inside files like `expressServer.js`, `handler.js`, `registerAliases.js`, and `validator.js`) hardcodes the `.js` extension when resolving and requiring key entry points (e.g., `server/index.js`, `server/server.js`, `server/document.js`, `src/js/store/index.js`, `src/js/routes/utils.js`, `src/js/containers/App/index.js`, and `client/index.js`). Renaming these files to `.ts`/`.tsx` causes the validator to fail and the build/runtime server to crash wit

### Enhancing catalyst-mcp: Dynamic AST indexing, active diagnostics, and robust classification

## Motivation

The catalyst-mcp server currently relies on a static knowledge-base.json that is subject to doc-drift/staleness, lacks runtime diagnostics (e.g. detecting port collisions or Babel config conflicts), references transpiled ES5 production code, and uses a strict scope classifier that occasionally blocks valid queries.

## Proposed Behaviour

1. **Dynamic Code Indexing:** Supplement static KB queries with dynamic AST indexing over node_modules/catalyst-core.
2. **Active Diagnostics ('

### Automatic eager-loading and scoping of catalyst-mcp tools in Catalyst projects

## Motivation

When working in a Catalyst project, the developer and assistant must still manually search schemas and explicitly scope 'catalyst-mcp' for any query, rather than having Catalyst-specific tools pre-registered eagerly by default.

## Proposed Behaviour

All 'catalyst-mcp' tools should be eagerly loaded and registered by default for any Catalyst workspace (e.g. available as direct 'mcp_catalyst_mcp_*' tools). This allows the assistant to call Catalyst checks and operations instantly.

### Friction in catalyst-mcp configuration: absolute Node path requirements, manual file edits, and tool scoping

## Motivation

Setting up the Catalyst MCP server requires manual global file modification (finding ~/.gemini/antigravity-ide/mcp_config.json vs ~/.gemini/config/mcp_config.json), absolute path node binary resolution (/usr/local/bin/node instead of just node), manual IDE restarts to apply settings, and explicit catalyst-mcp scoping for tool execution.

## Proposed Behaviour

1. **Workspace Auto-Discovery:** Catalyst should support workspace-local MCP server detection (e.g. via .agents/mcp_config

### Clarification on PUBLIC_STATIC_ASSET_URL for cloud deployments (e.g. Railway)

## Context

PUBLIC_STATIC_ASSET_URL is hardcoded in config.json as 'http://localhost:3005', leading to broken assets in production deployment.

## Expected Guidance

There should be a documented best practice or dynamic fallback for PUBLIC_STATIC_ASSET_URL. For example, if deployed to cloud platforms (like Railway), the build/runtime should automatically default to relative pathing (/assets/) or respect process.env.PUBLIC_STATIC_ASSET_URL dynamically.

### Missing native .env loader support for environment secrets

## Motivation

Developers must commit secrets to config/config.json or manually parse .env inside preServerInit.

## Proposed Behaviour

Catalyst should support loading .env configurations natively (using dotenv or Node's --env-file) so that local secrets are gitignored out of the box.

## Proposed Fix

Integrate a standard environment variable loader (like dotenv) or support Node.js's native --env-file option in catalyst-core's startup scripts, loading .env variables into process.env before val

### bug: classifyIntent feedback pattern matches standalone word 'issue' — misroutes debug queries as GitHub issue creation

## Summary

The `feedback` intent regex in `mcp_v2/mcp.js` includes the standalone word `issue` as an alternative match. This causes any query naturally using the word "issue" (e.g. `"I have an issue with routing"`) to be classified as `feedback` intent — triggering the GitHub issue creation workflow instead of the debug flow.

## Current Behaviour

Any query containing the word `"issue"` without strong debug co-signals (error/fail/why) can get classified as `feedback` — causing the LLM to launc
