Masks the document locally, packs it with the terraform source into + an archive, uploads it, creates a StackGuardian run, polls it and reports the verdict as JSON + and/or markdown. +- `ExitStatus.ERROR_POLICY_FAILED` (3), so a caller can tell "a policy said no" from "tirith could + not reach the platform". Exit 1 stays reserved for the latter, and applies even without + `--fail-on-error`: a run that produced no verdict must never look like a pass. + +### Changed +- `cli.main(args=...)` is now honoured. It previously called `parse_args()` with no argument, so + the parameter was ignored and the CLI could only ever read `sys.argv`. + +### Notes +- The local evaluation surface is unchanged, including its single-dash long options. Subcommands + are dispatched before the flat parser sees anything, so `--json` output stays byte-identical. +- No new runtime dependencies: the platform integration is stdlib-only. + +## [1.1.0] - 2026-08-01 + +### Added +- `core`: Policy metadata passthrough — `meta.id`, `meta.name`, `meta.description`, + `meta.severity`, `meta.enforcement`, `meta.tags` and `meta.remediation` now reach the result + document when a policy declares them. Keys that are absent are omitted, so the output of a + policy declaring none of them is unchanged. `{{ var.x }}` substitution works in all of them. + +### Fixed +- `core`: Variable substitution no longer mutates the caller's policy dictionary. Evaluating the + same parsed policy more than once (a policy set, or a retry) previously leaked substituted + values from one evaluation into the next. +- `core`: An unsupported `condition.type` now populates `result` instead of returning without it, + which raised `KeyError` in the pretty printer far from the real cause. +- `core`: Provider errors reported without a `ProviderError` severity are now surfaced instead of + being discarded and `None` evaluated against the condition — a typo'd `operation_type` read as + a genuine policy violation. These are treated as malformed provider calls and are deliberately + not subject to `error_tolerance`. + ## [1.0.5] - 2025-11-19 ### Fixed diff --git a/README.md b/README.md index 786a16e5..d410d3e6 100644 --- a/README.md +++ b/README.md @@ -1,4 +1,4 @@ -[![Contributor Covenant](https://img.shields.io/badge/Contributor%20Covenant-2.1-4baaaa.svg)](code_of_conduct.md) +[![Contributor Covenant](https://img.shields.io/badge/Contributor%20Covenant-2.1-4baaaa.svg)](CODE_OF_CONDUCT.md) [![Code style: black](https://img.shields.io/badge/code%20style-black-000000.svg)](https://github.com/psf/black) [![Quality Gate Status](https://sonarcloud.io/api/project_badges/measure?project=StackGuardian_policy-framework&metric=alert_status&token=4a4d06e73940505edb7fc9d27a7f03b35fbbf23d)](https://sonarcloud.io/summary/new_code?id=StackGuardian_policy-framework) [![Maintainability Rating](https://sonarcloud.io/api/project_badges/measure?project=StackGuardian_policy-framework&metric=sqale_rating&token=4a4d06e73940505edb7fc9d27a7f03b35fbbf23d)](https://sonarcloud.io/summary/new_code?id=StackGuardian_policy-framework) @@ -26,6 +26,8 @@ Tirith scans declarative Infrastructure as Code (IaC) configurations like Terraf - [Features](#features) - [Installation](#installation) - [Usage](#usage) +- [Exit codes](#exit-codes) +- [Evaluating against your StackGuardian organization](#evaluating-against-your-stackguardian-organization) - [Example Tirith policies](#example-tirith-policies) - [Terraform Plan](#terraform-plan-provider) - [Infracost](#infracost-provider) @@ -89,8 +91,8 @@ pip install git+https://github.com/StackGuardian/tirith.git - Clone the repository to your local machine: ```bash - git clone - cd + git clone https://github.com/StackGuardian/tirith.git + cd tirith ``` - Start the Docker Engine using docker desktop or CLI. @@ -143,8 +145,7 @@ pip install -e . ``` tirith --version -1.0.0-beta.12 - +tirith 1.2.0 ``` Congratulations!
