Code Review
This pull request introduces a shared security pipeline, process_inbound_telegram_message, to ensure consistent access control enforcement across both standalone Telegram bots and gateway polling. It also adds a comprehensive suite of unit tests to verify user/channel allowlists, group policies, and pairing integration. The reviewer feedback highlights a logical bug in group policy enforcement where default values can override explicit settings, and recommends mocking PairingStore in unit tests to prevent side effects on the local filesystem.

In server.py, group_policy is not passed to BotConfig (only mention_required is passed). If BotConfig has a default value of 'mention_only' for group_policy, then getattr(bot.config, 'group_policy') will always return 'mention_only', overriding any custom group_policy (like 'allow_all') configured in gateway.yaml because group_policy == 'mention_only' or mention_required will evaluate to True even if mention_required is False.
To fix this, we should prioritize mention_required when it is explicitly set to False, and also respect group_policy when it is explicitly set to something other than 'mention_only'.

The PairingStore class is instantiated during TelegramBot initialization, which triggers file operations on the real home directory (~/.praisonai/gateway/pairing.json). This can cause side effects on the developer's machine and lead to flaky tests.
We should mock PairingStore using a pytest fixture to ensure the tests are fully isolated and do not touch the real filesystem.

Test may fail: UnknownUserHandler.handle is not mocked.
When the user is not in allowed_users, the pipeline delegates to UnknownUserHandler.handle(). This test doesn't mock that handler, so the assertion on line 94 depends on the real handler's behavior, which may cause unexpected failures or pass for the wrong reason.

Pull request overview
This PR addresses issue #1747 by ensuring inbound Telegram messages received via the gateway polling loop go through the same access-control/security enforcement as the standalone Telegram bot path, eliminating a bypass that allowed unauthorized users to reach agent.chat().
Changes:
- Extracts a shared inbound Telegram security pipeline (
process_inbound_telegram_message) and uses it in both the standalone bot runtime and the gateway polling handler. - Updates the gateway Telegram polling handler to drop messages rejected by channel/user/pairing/group-policy checks before routing to an agent.
- Adds unit tests intended to validate allowlist, group policy, pairing integration, and audio transcription behavior.

1. allowed_users bypassed via pairing 📎 Requirement gap ⛨ Security
In process_inbound_telegram_message(), users not in allowed_users can still be permitted if UnknownUserHandler.handle() returns True (e.g., already paired or policy allows), which can allow unauthorized users to reach _session.chat() in gateway polling mode.
Agent Prompt
## Issue description
Gateway polling must enforce `BotConfig.allowed_users` as a hard allowlist before any chat/LLM call. The current shared pipeline allows `UnknownUserHandler.handle()` to override `allowed_users`, enabling unauthorized users to proceed.
## Issue Context
`process_inbound_telegram_message()` is used by gateway polling and the standalone bot path. With `allowed_users` set (e.g., `["42"]`), a user like `99` must not be able to reach `_session.chat()` regardless of pairing state or unknown-user policy.

2. Group policy command_only bypass 📎 Requirement gap ⛨ Security
The shared pipeline’s group gating in process_inbound_telegram_message() does not correctly implement BotConfig.group_policy semantics: it applies mention-gating whenever mention_required is true and fails to properly enforce command_only (and can also mis-gate respond_all). This can cause incorrect allow/deny behavior, including responding to non-command group messages when policy should suppress replies or dropping messages when respond_all should allow them.
Agent Prompt
## Issue description
Group message gating must correctly enforce the configured `BotConfig.group_policy` semantics (`respond_all`, `mention_only`, `command_only`) and only apply `mention_required` in a way that does not override those policies, so that disallowed group messages are dropped before the bot/gateway responds.
## Issue Context
- `BotConfig.group_policy` explicitly supports `respond_all`, `mention_only`, and `command_only`.
- The shared pipeline is intended to unify enforcement across standalone + gateway, and PR Compliance ID 3 requires that gateway polling enforce group policy/mention requirements before responding.
- Current logic applies mention gating whenever `mention_required` is true (e.g., via `if group_policy == "mention_only" or mention_required`), which can unintentionally allow mention-based replies under `command_only` and can unintentionally require mentions under `respond_all`.
## Fix Focus Areas
- src/praisonai/praisonai/bots/telegram.py[880-896]
- src/praisonai-agents/praisonaiagents/bots/config.py[50-52]
## What to change
- Replace the current mention-gating OR condition with explicit policy dispatch:
- `respond_all`: allow group messages (no mention required)
- `mention_only`: allow only if bot is mentioned OR message is a command
- `command_only`: allow only commands
- If backwards compatibility with `mention_required` is needed, use it only as a fallback when `group_policy` is unset/empty, not as an overriding OR condition.

3. Empty allowlist drops all 🐞 Bug ≡ Correctness
process_inbound_telegram_message() treats users as “not explicitly allowed” when allowed_users is empty and then invokes UnknownUserHandler.handle(); with BotConfig.unknown_user_policy defaulting to "deny", this drops all inbound messages instead of allowing all (the documented empty-allowlist behavior). This will also make the new test_empty_allowlists_allow_all fail and contradicts the gateway warning that empty allowed_users “accepts messages from everyone.”
Agent Prompt
### Issue description
`process_inbound_telegram_message()` currently routes *all* users through `UnknownUserHandler` when `allowed_users` is empty because it uses `bool(config.allowed_users) and is_user_allowed(...)`. Since `BotConfig.unknown_user_policy` defaults to `"deny"`, this causes silent drops for every inbound message whenever no allowlist is configured, contradicting `BotConfig.is_user_allowed()` semantics (empty list => allow all) and the gateway warning text.
### Issue Context
This pipeline is now used by the gateway polling handler, so it can turn previously-working “open” gateway Telegram bots into bots that respond to nobody.
### Fix Focus Areas
- src/praisonai/praisonai/bots/telegram.py[857-878]
- src/praisonai/tests/unit/gateway/test_telegram_security_pipeline.py[186-197]
### What to change
- Replace `is_explicitly_allowed = bool(config.allowed_users) and config.is_user_allowed(user_id)` with logic based on `config.is_user_allowed(user_id)` (or explicitly gate UnknownUserHandler behind `if config.allowed_users and not config.is_user_allowed(user_id):`).
- Only call `UnknownUserHandler.handle(...)` when the allowlist is configured and the user is not in it (so empty allowlist truly means allow all, matching `BotConfig`).
- Update the unit tests accordingly (they currently assert allow-all for empty allowlists).

Gateway extracts group_policy from gateway.yaml but does not pass it into BotConfig; the new shared pipeline then reads bot.config.group_policy and defaults to "mention_only", so gateway Telegram will silently ignore respond_all/command_only and enforce mention-only behavior. This is a security/configuration correctness break because command_only becomes more permissive (mentions allowed) than configured.
Agent Prompt
### Issue description
In gateway mode, the config loader computes `group_policy` but only forwards `mention_required` into `BotConfig`. The new shared Telegram pipeline uses `bot.config.group_policy` for enforcement, so gateway ends up using `BotConfig`’s default `group_policy="mention_only"` regardless of gateway.yaml.
### Issue Context
This impacts the gateway polling path newly wired to `process_inbound_telegram_message()`.
### Fix Focus Areas
- src/praisonai/praisonai/gateway/server.py[1593-1612]
- src/praisonai/praisonai/bots/telegram.py[883-887]
### What to change
- In `gateway/server.py`, include `group_policy=group_policy` in `config_kwargs` when constructing `BotConfig`.
- Then rely on `group_policy` in the shared pipeline (and implement the full policy handling per the other finding).

Silent standalone-bot access-control regression for empty
allowed_users
The old handle_message gated pairing with bool(self.config.allowed_users) and self.config.is_user_allowed(user_id): when allowed_users is empty, this evaluated to False, so every user entered UnknownUserHandler. With the default unknown_user_policy = "deny", that handler rejected everyone. The new pipeline calls bot.config.is_user_allowed(user_id) directly, which returns True for an empty list — so when no allowlist is configured, all users bypass UnknownUserHandler entirely.
Concrete failure: a standalone bot deployed with unknown_user_policy = "pair" (requires explicit owner approval) and no allowed_users list relied on this gate to require pairing before any user could interact. After this change, the pairing system is never invoked and the bot accepts every message without approval.
Fixes security follow-up from #1791. Includes regression tests for Telegram allowlist and MCP queue concurrency.
Fixes #1747
This PR addresses a critical security vulnerability where the gateway Telegram polling path bypassed access control enforcement, allowing unauthorized users to interact with agents.
