Exercise 3: A ufw Role That Runs Clean But Does Nothing — Possible Solution
====================================================================

-- Most likely explanation --
--
-- Per the chapter's own warn-box, this exact symptom -- a role that
-- reports success with no errors, but visibly accomplishes nothing --
-- is the signature of a typo'd or misnamed directory somewhere inside
-- the role, most commonly tasks/ being misspelled as task/ (singular)
-- or placed at the wrong path entirely. Because Ansible loads role
-- tasks purely by convention, based on the directory actually being
-- named tasks/, a misnamed folder means Ansible simply finds nothing
-- there to run -- it doesn't raise an error, doesn't warn that
-- something looks missing, and doesn't fail the play. It just quietly
-- treats the role as having zero tasks, which is exactly consistent
-- with "runs successfully" (nothing to fail) combined with "does
-- nothing" (nothing was ever actually run).

-- How to confirm it --
--
-- The most direct check is simply listing the contents of the
-- roles/ufw/ directory and confirming the folder is spelled exactly
-- "tasks" (not "task", not "Tasks", not placed one level too deep or
-- too shallow). A second, more diagnostic confirmation is running the
-- playbook with increased verbosity (ansible-playbook -vv), which
-- will show, for each role, which task files Ansible actually
-- discovered and attempted to include -- if the ufw role's own task
-- file is genuinely missing from that output, that directly confirms
-- the directory-naming problem rather than, say, every individual
-- task inside tasks/main.yml happening to be skipped by a when:
-- condition instead.

WHY THIS WORKS AS AN ANSWER
------------------------------
This identifies the specific failure mode the chapter's own warn-box
names (a silently misnamed tasks/ directory) as the most likely cause
given the described symptoms, then proposes two concrete, distinct
ways to confirm it rather than a single vague "check the role."
