Telegram Allowlist Hardening

Date: 2026-01-05
Status: Complete
PR: #216

Summary​

Telegram allowlists now accept telegram: and tg: prefixes case-insensitively, and tolerate accidental whitespace. This aligns inbound allowlist checks with outbound send normalization.

What changed​

  • Prefixes telegram: and tg: are treated the same (case-insensitive).
  • Allowlist entries are trimmed; empty entries are ignored.

Examples​

All of these are accepted for the same ID:

  • telegram:123456
  • TG:123456
  • tg:123456

Why it matters​

Copy/paste from logs or chat IDs often includes prefixes and whitespace. Normalizing avoids false negatives when deciding whether to respond in DMs or groups.
