Summary

GatewayBrowserClient in ui/src/ui/gateway.ts uses several raw magic numbers to control WebSocket reconnect behavior. These numbers have no names or comments, making the reconnect logic difficult to understand, tune, or safely modify.

Steps to reproduce

1. Open ui/src/ui/gateway.ts
2. Search for backoffMs
3. Observe raw numbers: 800, 1.7, 15_000, and 750 scattered across the class with no explanation

Expected behavior

Reconnect-related values should be defined as named, documented constants at the top of the file so their purpose is clear and they can be adjusted in one place:

const INITIAL_BACKOFF_MS = 800;
const MAX_BACKOFF_MS = 15_000;
const BACKOFF_MULTIPLIER = 1.7;
const CONNECT_QUEUE_DELAY_MS = 750;

Actual behavior

Raw numbers are hardcoded inline across multiple methods with no documentation:

private backoffMs = 800;
this.backoffMs = Math.min(this.backoffMs * 1.7, 15_000);
this.backoffMs = 800; // reset on success
window.setTimeout(..., 750);

Logs, screenshots, and evidence

Relevant code from ui/src/ui/gateway.ts:

// Line 73 — initial value (magic number)
private backoffMs = 800;

// Line 117 — backoff growth and cap (magic numbers)
this.backoffMs = Math.min(this.backoffMs * 1.7, 15_000);

// Line 227 — reset on successful connect (magic number)
this.backoffMs = 800;

// Line 310 — connect queue delay (magic number)
this.connectTimer = window.setTimeout(() => {
  void this.sendConnect();
}, 750);

No crash or functional bug — this is a maintainability/readability issue in the source code.
