Ansible Role: Audita

Installs and configures Audita from source on Ubuntu 26.04 (x86_64 or aarch64). The role requires gathered facts and uses privilege escalation on tasks that install dependencies or manage root-owned application state.

Variables

Every invocation requires caller-supplied audita_backends and audita_llm_proposal_profile. Neither has a role default.

When audita_manage_build_dependencies is false, Git and the executable selected by audita_go_binary must already be available. Otherwise, the role installs Git with APT and the classic Go Snap from audita_go_snap_channel.

The checkout is authoritative: local source changes are discarded while selecting audita_version. The role builds Audita directly to audita_binary_path using audita_go_binary, CGO_ENABLED=0, GOWORK=off, GOTOOLCHAIN=local, -trimpath, and release linker metadata. It rebuilds when the checkout changes or the binary is absent. The source tree is recursively owned by root:root; the binary is root:root mode 0755.

The configuration variables map directly to Audita's version-2 YAML fields. audita_backends and audita_llm_proposal_profile are required caller inputs; the role has no defaults for them. Callers own the selected PromptKit profile files. Every optional variable defaults to null; null values and their empty parent sections are omitted, allowing Audita to retain ownership of its built-in defaults. audita_config_version always renders as version and defaults to 2. The role manages audita_config_path | dirname and the resulting file with the audita_config_owner, audita_config_group, audita_config_directory_mode, and audita_config_file_mode inputs. The standalone defaults are root:root, directory mode 0755, and file mode 0644. Composing roles may override these generic configuration inputs for their own deployment policy.

Backend credential values are explicit environment-variable reference names, not secret values. Every surviving reference must resolve to a nonempty value when Audita loads configuration, including references on unselected backends. An omitted or null credential permits unauthenticated local use. The role does not supply secret values, start a service, or probe profiles during convergence.

Migrating from the version-1 role

This revision renders version-2 configuration only. Existing version-1 users can retain the previous role revision while planning a coordinated migration. The old fields have no compatibility aliases:

Previous role inputs	Version-2 destination
audita_llm_{proposal,validation}_base_url	audita_backends.<id>.endpoint; both selections may share one backend.
audita_llm_{proposal,validation}_api_key_env	audita_backends.<id>.credential, an explicit environment-variable name.
audita_concurrency_{total_llm,proposal_llm,validation_llm}	audita_backends.<id>.concurrency and optional queue_capacity; capacity is shared by roles using that backend.
audita_llm_{proposal,validation}_model	Model in caller-owned PromptKit profile files, selected by audita_llm_proposal_profile and optional audita_llm_validation_profile.
audita_llm_{proposal,validation}_timeout	Per-attempt timeout_seconds in profile files; audita_llm_operation_timeout separately bounds a logical call.
audita_llm_{proposal,validation}_max_retries	audita_llm_transient_retries and audita_llm_repair_attempts are separate native budgets; old values do not map directly.
Three audita_normalization_* gap/duration values	Same role variables, now numeric seconds rather than duration strings.
audita_diagnostics_retention	Removed; use audita_diagnostics_debug and audita_diagnostics_work_dir for v2 debug behavior. Reporting uses audita_reporting_enabled and audita_reporting_stdout_dir.

Omitting audita_llm_validation_profile lets Audita inherit the proposal selection. audita_llm_operation_timeout is a Go duration string, while normalization times are numbers. See the tagged v2 migration guide and configuration reference for exact validation and precedence rules.

Example

Inventory can supply the required choices for a local backend:

# host_vars/audita_host.yml (caller-owned)
audita_backends:
  local:
    endpoint: http://127.0.0.1:11434/v1
    credential: null
audita_llm_proposal_profile: local-proposal

The caller also supplies profiles/local-proposal.yaml beside the managed configuration, or selects another directory with audita_profiles_dir:

# profiles/local-proposal.yaml (caller-owned)
id: local-proposal
backend: local
model: replace-with-an-available-local-model
timeout_seconds: 30

Choose a model available at the selected endpoint. These profile files must exist before invoking Audita, but need not exist before applying the role. The role neither deploys them nor selects a ConfigKit overlay.

Validation

The integration driver installs pinned collection dependencies, runs syntax checking and ansible-lint, and applies the role with local fixture backends and caller-owned profiles. It checks the temporary configuration with native config validate and the effective settings and profiles views, then requires clean repeated convergence. It also tests a caller-supplied Go executable with dependency management disabled after removing the managed binary. The fixture configuration and sibling profiles/ directory live under the script's private temporary root, which cleanup removes. The role still mutates the local managed source checkout and binary; an existing system configuration is not replaced. These offline checks do not establish provider connectivity, runtime report behavior, or compatibility with the unchanged D&D suite:
