Two fixes, both filed rather than deferred.
1. member-portal#2 — the sweep deactivates every member whose email is missing
from the Open Collective member list, and the existing fail-safe only covers a
fetch that RAISES. A fetch that SUCCEEDS while returning nothing or far less
than usual is unguarded, and is what a narrowed token scope, an expired
credential with partial access, or a renamed Membership tier produces (the
fetch filters on the tier's name). That path deactivates the membership
instead of failing. fetch_members() now checks the result against the local
active count before any caller can act on it: empty, or at or below half of
local, raises — so the sweep's fail-safe takes over and members stay active.
Skipped when we have no active members of our own (fresh install).
Correction to the issue as filed: listmonk_reconcile reads the local members
table, not this fetch, so the newsletter path was never exposed to it. The
sweep is the only destructive consumer.
2. ops/security#2 — OC's generic webhooks cannot send headers, so the webhook
secret must travel in the URL path, and uvicorn wrote it into the access log
on every delivery. A logging filter on uvicorn.access and on the root handler
replaces the token with <redacted>. The token cannot be kept out of the URL;
it can be kept out of the retention.
Both pieces are unit-tested in isolation before shipping: the guard's decision
function over eight cases, and the filter against a real access-log record, an
unrelated path (no over-redaction), and a missing dependency (must not break
logging).
