Project description:
"I need an Erlang-savvy developer to extend ejabberd’s mod_roster so it handles presence subscriptions on server differently. The focus is advanced subscription management, specifically:

- custom ejabberd module to hook mod_roster
I need presence to be set on both when both but only when contacts have each other in roster. If not both have each other in roster it should be set to none

• Automated subscription approvals that follow clear, configurable rules.

The finished work should compile cleanly against the current ejabberd release, slot into the normal modules directory, and respect all existing hooks so other components continue to work. Please include:

1. The patched or new .erl file plus compiled .beam.
2. A brief config snippet showing how to enable and adjust the new options.
3. Unit tests (eunit or common-test) proving the new logic.
4. A short README walking through build, deploy, and rollback steps.

PLEASE NO GENERIC BIDDING, IF YOU READ THIS PUT TITLE OF YOUR BID AS: "MOD_ROSTER BID" THEN I WILL READ/CONSIDER THE BID.

IF SOMEONE ALREADY HAS HAVE THIS MODULE MADE BEFORE IT WOULD BE GLADLY APPRECIATED AS IT IS NEEDED ASAP

I’ll provide a test server and can run your branch if you prefer working in a public fork. Code quality, clear comments, and sensible error handling are essential; I want to drop this straight into staging and see green bars." (client-provided description)
