v0.52.11: Tela-server: Resolved entry html rawURL

Here’s a short, clean GitHub-ready summary of the fix and reasoning, focusing on rawURL + baseURL 👇

Summary: Fix SCID reloads & non-index.html entrypoints (rawURL + baseURL)

Problem

• Some TELA SCIDs do not use index.html (e.g. Snake Deluxe.html, algo4.html)
• Electron is not forgiving with redirects or / → HTML resolution
• Reloading a previously opened SCID failed because /add/<SCID> returned only "OK" without the actual entry URL
• BrowserView needs the exact HTML entry file, not just /tela/<SCID>/

Root Cause

• tela-server internally knows the real entry file (rawURL)
• But on idempotent reloads, the server discarded it
• Electron then tried to load an empty or incorrect URL → ERR_INVALID_URL, redirect loops, or blank pages

---

Solution

1️⃣ Track two URLs per SCID

• rawURL → exact HTML entry file
  Example:

  http://localhost:8084/Snake Deluxe.html
  

• baseURL → directory root for assets & proxying
  Example:

  http://localhost:8084/
  

---

2️⃣ Return rawURL even when SCID is already loaded

if alreadyLoaded {
    fmt.Fprintf(w, "OK (already loaded): %s", rawURL)
    return
}

This guarantees:

• First load ✅
• Reload after tab close ✅
• Non-index.html SCIDs ✅

---

3️⃣ Electron always loads the returned URL

const addRes = await fetch(`/add/${scid}?node=...`);
const text = await addRes.text();

let scidURL;
if (text.startsWith("OK: ")) {
  scidURL = text.slice(4).trim();
} else if (text.startsWith("OK (already loaded): ")) {
  scidURL = text.slice("OK (already loaded): ".length).trim();
}

await view.webContents.loadURL(encodeURI(scidURL));

---

Result

✅ SCIDs with index.html
✅ SCIDs with custom HTML filenames
✅ Reloading SCIDs after tab close
✅ No redirects, no timeouts, no Electron quirks

---

TL;DR

Return rawURL on every /add/<SCID> call (new or already loaded).
Use baseURL only for proxying assets.

This keeps Electron happy without forcing index.html rewrites 🚀
