The traversal value is normally a valid HCL string, but can be
simplified if a traversal step has a complex index value (e.g. an
object). This means it is not always parseable HCL, so this commit
updates the documentation to clarify this and explicitly record that we
do not guarantee its contents are stable. The purpose of these values is
purely for building human-readable UI.
In line with the other complex JSON output formats for plan and provider
schema, here we add an explicit `format_version` field to the JSON
output of terraform validate.
Fixes#27506
Add a new flag `-lockfile=readonly` to `terraform init`.
It would be useful to allow us to suppress dependency lockfile changes
explicitly.
The type of the `-lockfile` flag is string rather than bool, leaving
room for future extensions to other behavior variants.
The readonly mode suppresses lockfile changes, but should verify
checksums against the information already recorded. It should conflict
with the `-upgrade` flag.
Note: In the original use-case described in #27506, I would like to
suppress adding zh hashes, but a test code here suppresses adding h1
hashes because it's easy for testing.

Since this is still at an early phase and likely to change significantly
in future iterations, rather than attempting to guess on a suitable final
location for documenting the testing feature I've instead taken the
unusual approach of adding a new page that is explicitly about the
experiment. My expectation is that once we conclude the experiment we'll
replace this new page with a stub that just explains that there was once
an experiment and then links to whatever final feature unfolded from the
research.
The URL for this page is hard-coded into the warning message in the
"terraform test" command, so as we continue to evolve this feature in
future releases we'll need to update the callout note on the page about
which Terraform CLI version it's currently talking about, so users of
older versions can clearly see when they'd need to upgrade in order to
participate in a later incarnation of the experiment.
To make the command arguments easier to understand and extend, we are
moving away from positional arguments. This commit changes the graph
command to take a `-plan` flag instead of an optional trailing path.
