[dogfood 2026-09-23] Unknown paths soft-route to Ask UI

[jon-devlapaz]

Severity

smell / low

Summary

Invented deep links (/foo, /chat, /ask/xyz) soft-fail into the Ask UI instead of 404; prior chat can reappear; invalid URL stays in the address bar.

Repro

1. Open https://ask-jdp.marten-pollux.ts.net/
2. Navigate to /foo, /chat, or /ask/xyz.

Expected vs actual

• Expected: 404 (or explicit unknown-route handling) for invented paths.
• Actual: Soft-routes into Ask UI; prior chat may reappear; address bar keeps invalid URL.
