name = "{0} should be a palindrome" is the whole trick: {0} is a positional reference to the
single @ValueSource argument, and the console runner always quotes a String argument's own text
when it substitutes it in -- which is why the output reads "racecar" should be a palindrome
rather than requiring quotes inside the template itself. An earlier draft of this template used
name = "''{0}'' should be a palindrome", which doubles up with the console's own quoting and
renders as the much uglier '"racecar"' should be a palindrome -- fixed here before publishing by
simply dropping the extra quote marks from the template.

Five invocations, not three: @NullAndEmptySource contributes the null and "" cases, and the
@ValueSource(strings = {" ", "\t", "\n"}) alongside it contributes the other three. All five are
blank per String.isBlank() -- which is the actual point of the test, and the reason it needs real
tab and newline characters rather than the letters "t" and "n", which are not blank at all.

This is the genuinely new, easy-to-miss finding in this rewrite. The custom template is
name = "user {0} with role {1}" -- plain positional placeholders, the same {0}/{1} syntax used
everywhere else in this module. But because @CsvSource(useHeadersInDisplayName = true) is also
set, each individual {0} and {1} does not resolve to the bare value ("1001", "EDITOR") the way
it would without that flag -- it resolves to "HEADER = value" ("USER_ID = \"1001\"",
"ROLE = \"EDITOR\""). useHeadersInDisplayName changes what every positional placeholder expands
to, not just the auto-generated default name used when no custom name is given at all. Compare
this against docs/output/05-csv-source-headers-default-display-name.txt (no custom name, same
data, same flag) and docs/output/06-header-name-placeholder-throws.txt (an attempt to put the
header name directly inside the template, which is a different thing entirely and throws).

With no custom name, useHeadersInDisplayName = true changes JUnit's own auto-generated default
from the bare [1] "1001", "EDITOR", "true" you would otherwise get to the header-qualified
[1] USER_ID = "1001", ROLE = "EDITOR", CAN_PUBLISH = "true" shown here. That is the documented,
intended effect of the flag. The surprise in
docs/output/04-csv-source-custom-name-with-headers.txt is that the exact same flag also changes
what a *custom* name's positional placeholders resolve to, which is easy to miss if you only
ever tested the flag against the default name.

The stack trace gives away the mechanism: @ParameterizedTest's `name` attribute is not its own
template language -- it compiles down to a real java.text.MessageFormat pattern, and
MessageFormat only understands numeric argument indices ({0}, {1}, ...). "USER_ID" is not a
number, so MessageFormat's own pattern parser throws NumberFormatException trying to read it
as one, before the test ever runs a single invocation. useHeadersInDisplayName = true changes
what JUnit generates automatically when no custom name is given (see
docs/output/05-csv-source-headers-default-display-name.txt) -- it does not add a new kind of
placeholder you can reference yourself.

privilegedRolesShouldHaveWriteAccess uses mode = INCLUDE with names = {"ADMIN", "SUPERUSER"},

The second invocation fails with exactly the same assertion, same line number, same test
method -- but now expects 1 and gets 2, because it is the SAME Config instance the first
invocation already touched. Nothing about invocation 2's own code is wrong; the bug is that
sharedProvider() built one Config and handed it to both Arguments.of(...) calls. This is
exactly the failure mode the "fresh instance per invocation" fix in goodFreshConfigIsAlwaysTouchedOnce
avoids -- that test passes all the way through for the identical reason this one fails.

freshProvider() builds a new Config() inside the Stream for each Arguments.of(...) call, so each
invocation gets its own isolated instance -- the whole fix is that simple. Both display names
read Config[callCount=0], which is correct and not a bug: JUnit resolves each invocation's
display name from the argument's toString() at argument-resolution time, before the test method
body (and its config.touch() call) has run, so callCount is still 0 at the moment the name is
built even though the assertion afterwards confirms it becomes 1.

activeUserProvider() hands out three real User objects built with real LocalDate renewal dates.
alice's renewalDueDate is one day in the past but still inside the 3-day grace period
isActive() allows, and she's enabled -- active. bob's is 30 days in the future and he's
enabled -- active. carol's date is identical to alice's (one day in the past, still within the
grace period), but she's enabled = false -- and isActive() requires both conditions, so she's
inactive purely because of the enabled flag, not the date. All three outcomes match
User.isActive()'s real logic -- see the module README for why this differs from the original
post's version of the same example.

@ArgumentsSource(ScenarioArgumentsProvider.class) delegates argument production to a real,
separately-compiled class implementing ArgumentsProvider -- the escape hatch to reach for once a
data source needs more structure than @MethodSource's single static method comfortably holds
(loading fixtures, branching on environment, composing other providers). ScenarioArgumentsProvider
overrides the current provideArguments(ParameterDeclarations, ExtensionContext) overload rather
than the older single-argument form, which still compiles but is now deprecated.

The @ValueSource arguments are plain ISO-format date strings; @ConvertWith(DashDateConverter.class)
is what turns each one into a real java.time.LocalDate before the test method ever sees it, via
DashDateConverter's own SimpleArgumentConverter.convert() override. JUnit actually has an
implicit String-to-LocalDate conversion for this exact ISO shape, so this particular example
would work without @ConvertWith too -- it's shown here because the same mechanism is what you
reach for once the source strings need a format or extra validation JUnit's implicit converters
don't cover, and DashDateConverter.java is the smallest possible shape to build that converter
in when the need arises.

testPermissions is the BAD example: one parameterized test asserting two unrelated behaviors
(canDelete and canRead) per row, so a failure in either one just says "testPermissions failed"
without telling you which behavior broke. It passes here -- this is a design-smell illustration,
not a test that's expected to fail -- but a reader who only sees it pass has no way to tell
canDelete and canRead apart from the test name alone. adminShouldDelete and allRolesShouldRead
are the fix: the same two behaviors, split into two single-assertion parameterized tests, each
with a display name that says exactly what broke if it ever does.
