rootform check

check is the Policy gate. It evaluates selected Policies against a plan's Planned architecture, a state's Recorded architecture, or both sides of a comparison Form by default, then exits with one verdict. The input is a plan or state export, compiled with the project's Dialects, or a saved Form, loaded without compiling it again. check never serves, never changes the Form, and writes a Policy result that is separate from the Form.

Usage

rootform check <input> [options]

SHELL

Options

Target selection

Flag	Type	Default	Description
--side	string	""	sides of a comparison Form to evaluate: before|after|both; default: both
--stage	string	""	stage to evaluate: planned|refreshed|recorded; default: Planned for a plan, Recorded for a state; with a comparison Form, needs --side before or after

Policy selection

Flag	Type	Default	Description
--policy	stringArray	[]	evaluate only the Policies selector names: PACK.policy.NAME, PACK/NAME, a bare name, or PACK/*; repeatable
--policy-pack	stringArray	[]	add or replace the Policy Pack at path, a source directory or a compiled file, for this command only; repeatable

Output

Flag	Type	Default	Description
--details	bool	false	also list passed evaluations, Policy Pack identities, and diagnostic codes
--format	string	""	format of standard output, or of a single -o file without a recognized extension: text|json|markdown|sarif; default: text
-o, --output	stringArray	[]	write file; its extension selects the format: .json (the Policy result), .txt, .md, .sarif, or .sarif.json; repeatable

Rootform project

Flag	Type	Default	Description
--dialect	stringArray	[]	use Dialect source dir for this command only; repeatable
--locked	bool	false	refuse to run unless rootform.lock is valid
--project	string	""	read rootform.lock from project dir; paths stay relative to the working directory; default: the working directory

Advanced evidence settings

Flag	Type	Default	Description
--plan-complete	string	""	declare the plan complete; the only value is attested
--plan-file	string	""	pair the plan JSON with the saved plan file it was exported from, to enrich it; pairing compares version, timestamp, and configuration shape
--producer	string	""	declare the tool that produced the input: terraform|opentofu
--provider-map	stringArray	[]	map an observed provider to a binding, as observed=binding; repeatable
--require-enrichment	bool	false	refuse the input when its saved plan file does not pair with the plan JSON

Global options

Flag	Type	Default	Description
-h, --help	bool	false	show how to use rootform check
--color	mode	auto	color human output: auto|always|never; default: auto
--no-pager	bool	false	print a long report in full instead of opening it in less

Example

From a checkout of the repository, save the reviewed commerce plan as a Form, then check it against the example Policy Pack and keep every report:

rootform run examples/playground/commerce-platform/head/plan.json \
  --plan-file examples/playground/commerce-platform/head/plan.tfplan \
  --no-serve -o analysis.json
rootform check analysis.json --policy-pack policy-packs/baseline \
  -o results.json -o report.md -o results.sarif

Shell

Check summary OUTPUT

Policy check completed

Input          analysis.json
Origin         Plan (saved Form)
Stage          Planned
Policies       2 selected

Evaluations    2
Passed         2
Violated       0
Indeterminate  0

Verdict        PASSED

All selected evaluations passed.

Loading analysis.json (saved Form; no recompilation) on standard error confirms that the saved Form was evaluated as written. results.json is the Policy result, report.md the review report, and results.sarif a SARIF 2.1.0 log. Each report is written whatever the verdict.

Choose the evaluated stage

A plan is checked on Planned and a state on Recorded. A comparison Form is checked on both Before and After by default, each at the stage selected in the saved comparison for that side. --side before or --side after limits the check to one side; --side both names the default. --stage selects another stage of the input, or of the one side a comparison check names with --side before or --side after: refreshed when the plan has one, never a plan's reconstructed recorded stage. An absent stage stops the check with STAGE_UNAVAILABLE; Rootform never falls back to another stage. Comparisons, drift, and the drift report are never evaluated as architectures.

Select Policies

The active Policy Packs come from rootform.lock. --policy-pack adds or replaces one pack for this command without changing the lock, and --locked refuses it. Without --policy, check selects every Policy of the --policy-pack packs, or every Policy of every active pack when none is given. Each --policy selector (PACK/*, PACK/NAME, PACK.policy.NAME, or a unique NAME) narrows that selection before anything is linked; an unknown or ambiguous selector exits 2. Only packs holding a selected Policy are linked, against the semantics recorded in the Form. Reports name each Policy by the identity list and show print, PACK.policy.NAME; SARIF rule IDs keep PACK/NAME. A violation or an indeterminate evaluation lists the Policy, the resource, the Requirement the Policy declares, and the recorded Evidence that decided it.

Reports

Each requested report records the Policy result or review format for this check. See Outputs and exit status for exact formats, -o and --format behavior, stream separation, and output failures.

Exit status

Exit	Description
0	Every selected Policy passed on every requested side.
1	A selected Policy was violated on a requested side.
2	The command was used incorrectly.
3	No verdict: indeterminate, no target, nothing selected, a side that could not be evaluated, an input that was refused, or an invalid rootform.lock.
4	An input or report file could not be read or written.

A violation takes precedence over indeterminate results. Standard output states the verdict once, in the summary or in the --format output. Standard error carries progress, plus a code when the check stops before evaluating, such as STAGE_UNAVAILABLE or POLICY_UNAVAILABLE, or when a report cannot be written (OUTPUT_FAILED). Understand Policy outcomes walks through each outcome, and Policies and Policy Packs explains what a result proves.
