Preview only. This is a draft in the fork showing the exact text of the PR planned for massive-com/client-python. It will be closed, not merged, once the upstream PR is opened.

Fixes #<issue: F1b>

Subscribing to a wildcard such as A.* drops the other subscribed topics on the same channel. The match used t.startswith(channel), so:

• subscribe("A.*") also dropped AM.AAPL, and likewise for XA.*/XAS.* and C.*/CA.*/CAS.*;
• calling subscribe("A.*") a second time unsubscribed A.*, because the wildcard matched itself.

This PR compares the channel exactly and skips the wildcard itself, in subscribe() and unsubscribe(). Nothing else changes: as before, only topics already sent are checked.

client.subs = {"A.MSFT", "AM.AAPL"}  # already sent
client.subscribe("A.*")
client.scheduled_subs  # before: {"A.*"}  now: {"A.*", "AM.AAPL"}

Tests

• New test_websocket/test_wildcard.py: three unit tests that set subs directly, with no server. All three fail on master.
• make test and make lint pass on Python 3.10 and 3.14.

Independent of the other PRs.
