rakestraw.dnd_pipeline

Installs the D&D transcript-processing application suite by composing the standalone Seriatim, Audita, Notarius, Scriptorium, and Narratio roles. It supports Ubuntu 26.04 and Ansible Core 2.18 or newer. Downstream roles perform their own task-level privilege escalation, so a play does not need become. Supported host architectures are amd64 and arm64.

Installation

Install the role dependencies and their collection before applying this role:

ansible-galaxy role install -r requirements.yml
ansible-galaxy collection install -r collections/requirements.yml

The dependency manifest installs the roles under their canonical names: rakestraw.seriatim, rakestraw.audita, rakestraw.notarius, rakestraw.scriptorium, and rakestraw.narratio. It selects the compatible v0.1.0 release of each role. This standalone role is named rakestraw.dnd_pipeline.

- name: Install the D&D pipeline foundation
  hosts: pipeline_hosts
  gather_facts: true

      vars:
        dnd_pipeline_whisperx_transcribe_url: https://whisperx.example/transcribe

The collection source exposes a reviewed snapshot of this role as rakestraw.dnd.pipeline:

- name: Install the D&D pipeline from the collection
  hosts: pipeline_hosts
  gather_facts: true
  roles:
    - role: rakestraw.dnd.pipeline
      vars:
        dnd_pipeline_whisperx_transcribe_url: https://whisperx.example/transcribe

Collection consumers should follow the unified bootstrap instructions in the rakestraw.dnd collection repository. This standalone repository remains authoritative for role changes; collection maintainers import a reviewed, pushed commit or immutable tag as a snapshot. Collection releases are published independently and are listed in the collection repository.

Variables

dnd_pipeline_whisperx_transcribe_url is required and is passed to Narratio. The compatible application versions are selected through these variables:

Variable	Default
dnd_pipeline_audita_version	v0.9.1
dnd_pipeline_narratio_version	v2.1.0
dnd_pipeline_notarius_version	v0.7.0
dnd_pipeline_seriatim_version	v1.5.0
dnd_pipeline_scriptorium_version	v0.13.0
dnd_pipeline_manage_build_dependencies	true
dnd_pipeline_go_snap_channel	1.26/stable
dnd_pipeline_go_binary	/snap/bin/go
dnd_pipeline_campaigns_repository_url	https://gitea.maximumdirect.net/eric/campaigns.git
dnd_pipeline_campaigns_revision	main
dnd_pipeline_campaigns_root	/usr/local/share/narratio/campaigns
dnd_pipeline_prompt_library_repository_url	https://gitea.maximumdirect.net/eric/narratio-prompts.git
dnd_pipeline_prompt_library_revision	main
dnd_pipeline_prompt_library_root	/usr/local/share/narratio/prompt-library

The common dependency-management switch controls whether every application role installs Git and Go. Callers that disable it must provide both Git and Go. The Go channel and executable are likewise passed to all five roles. Advanced callers may supply unmapped standalone-role variables directly through normal Ansible variable precedence.

The following values are deliberate D&D suite policy passed through the standalone roles' generic configuration interfaces; they are not standalone defaults. Narratio runs first and establishes the selected runtime user and group before the remaining configuration-bearing dependencies run.

Variable	Default policy
dnd_pipeline_runtime_user	narratio
dnd_pipeline_runtime_group	narratio
dnd_pipeline_config_directory_mode	0755
dnd_pipeline_config_file_mode	0644

All application configuration, including pipeline-owned Narratio fragments, is therefore narratio:narratio, world-readable, and Ansible-managed. It is not an operator-editable configuration surface.

Narratio receives the standard Seriatim, Audita, Notarius, and Scriptorium binary and configuration paths managed by the composed roles. Notarius is enabled with the suite-owned dnd-session extraction pipeline.

The role deploys the campaign repository directly at the campaign root and the prompt library directly at the prompt-library root. By default both follow their main branches; callers can select an immutable commit, tag, or another branch through the revision variables. Narratio receives the deployed campaign root, while Scriptorium receives its prompts/ and schemas/ children.

D&D processing policy

The variables below are deliberate D&D suite policy, not a copy of application defaults. They remain ordinary inventory variables, so callers can replace a chosen policy value when their deployment requires it.

Variable group	Default policy
dnd_pipeline_audita_pipeline_modules	glossary, homophones, glossary, spoken_word, grammar
dnd_pipeline_audita_output_schema	audita-v1
dnd_pipeline_audita_llm_proposal_*	https://inference.ai.rakestrawhome.com/v1, google/gemma-4-31b-it, AUDITA_LLM_API_KEY, 900s, 3
dnd_pipeline_audita_llm_validation_*	https://inference.ai.rakestrawhome.com/v1, google/gemma-4-31b-it, AUDITA_LLM_API_KEY, 900s, 3
dnd_pipeline_audita_concurrency_*	total, proposal, and validation concurrency of 4
dnd_pipeline_audita_chunking_*	8 target sections, 6144 maximum and 2048 minimum section tokens
dnd_pipeline_audita_normalization_*	3s maximum and ellipsis gaps, 240s maximum duration, 2048 maximum tokens
dnd_pipeline_audita_thresholds_*	0.8 for glossary, homophones, spoken word, and grammar
dnd_pipeline_audita_context_description	D&D-game transcript context, including possible pre- and post-session banter
dnd_pipeline_audita_diagnostics_*	/tmp/audita, retained automatically

Audita's proposal and validation settings independently remain overrideable, but both default to the one typed AUDITA_LLM_API_KEY reference Narratio can forward. Audita owns its endpoint, model, tuning, and diagnostics configuration; Narratio receives its managed Audita configuration path and supplies the run-specific output path.

Variable	Default
dnd_pipeline_narratio_seriatim_output_schema	seriatim-intermediate
dnd_pipeline_narratio_normalize_output_path	transcripts/final.json
dnd_pipeline_narratio_normalize_output_schema	seriatim-intermediate
dnd_pipeline_narratio_trim_enabled	true
dnd_pipeline_narratio_trim_output_path	transcripts/final.trimmed.json
dnd_pipeline_narratio_trim_bounds_prompt_id	dnd.session_bounds
dnd_pipeline_narratio_trim_bounds_transcript_input_name	transcript
dnd_pipeline_narratio_trim_bounds_output_path	artifacts/session_bounds.json
dnd_pipeline_narratio_render_enabled	true
dnd_pipeline_narratio_render_format	markdown
dnd_pipeline_narratio_testing_scriptorium_profile	gemini-flash-latest

dnd_pipeline_audita_output_schema is also the Narratio Audita-adapter schema; it is the shared cross-application boundary. Other Narratio-local controls, including reports, timeouts, debug rendering, presentation, and bounds prompt profile selection, remain Narratio defaults.

Artifacts and profiles

The role owns these complete native mapping variables. Replacing one mapping changes that source's configuration as a whole; it does not change the fixed file name, import, or source key. Set enabled: false to retain an available source while excluding it from normal analysis.

Variable	Fixed source	Default state	Output
dnd_pipeline_narratio_session_recap_artifact	session_recap	enabled	artifacts/session_recap.md
dnd_pipeline_narratio_hostile_rumors_artifact	hostile_rumors	enabled	artifacts/hostile_rumors.md
dnd_pipeline_narratio_deranged_rumors_artifact	deranged_rumors	enabled	artifacts/deranged_rumors.md
dnd_pipeline_narratio_scene_map_artifact	scene_map	disabled	artifacts/scene_map.json
dnd_pipeline_narratio_character_analysis_family	character_meta_analysis	disabled	artifacts/character_meta_analysis/{character_id}.md

The character-analysis family expands over campaign party.characters and passes each member's name and class summary to its prompt. Recap and both rumor sources are enabled; the rumor input derives its recap dependency without a redundant explicit ordering edge. Production artifacts inherit each prompt's declared profile.

Narratio's root file remains owned by the standalone role. It imports the suite-owned base fragments in this fixed order:

/usr/local/etc/narratio/
├── pipeline.yml
├── conf.d/processing.yml
├── artifacts/session-recap.yml
├── artifacts/hostile-rumors.yml
├── artifacts/deranged-rumors.yml
├── artifacts/scene-map.yml
├── artifact-families/character-meta-analysis.yml
└── profiles/testing.yml

The testing profile is an overlay, not a second configuration tree. It only sets the Scriptorium profile_id for the four artifact sources and the one family. Its default, gemini-flash-latest, is an inexpensive development choice, not a compatibility guarantee. Replace it through inventory when a different testing profile is appropriate:

dnd_pipeline_narratio_testing_scriptorium_profile: endpoint-profile

Notarius extraction policy

The Notarius root configuration imports the fixed pipelines/dnd-session.yml fragment. The suite owns that fragment at /usr/local/etc/notarius/pipelines/dnd-session.yml; callers do not edit it.

Variable	Default policy
dnd_pipeline_notarius_pipelines	Complete native map containing dnd-session
dnd_pipeline_notarius_cache_root	/var/cache/notarius
dnd_pipeline_notarius_cache_chunk_plans_mode	auto
dnd_pipeline_notarius_cache_checkpoints_enabled	true
dnd_pipeline_narratio_notarius_pipeline_id	dnd-session
dnd_pipeline_narratio_notarius_llm_api_key	OPENROUTER_API_KEY
dnd_pipeline_narratio_notarius_resume	true
dnd_pipeline_narratio_notarius_references	party, players, and glossary prepared sources
dnd_pipeline_narratio_notarius_outputs	Complete native map of ten accepted D&D lanes

The pipeline, reference, and output values are complete native mappings. Inventory can replace them or compose additions with Jinja's combine filter; a replacement pipeline map requires a matching selected pipeline ID.

Narratio materializes the party, players, and glossary references for each invocation. No campaign filesystem path appears in Notarius configuration. The optional spell_catalog reference remains absent until a campaign supplies that input. The accepted sources are narratio.extraction.item_registry, npc_registry, location_registry, scene_descriptions, item_occurrences, spells, combat_turns, npc_occurrences, location_occurrences, and enemy_events.

Narratio forwards the typed OPENROUTER_API_KEY reference to the selected Notarius profile and ordinary extraction requests checkpoint reuse with resume: true. Chunk plans use Notarius's root-owned auto policy; the pipeline deliberately leaves Narratio's optional chunk_cache override unset. The chunk-plans and checkpoints paths derive from the cache root and are created by Notarius during use. Base and testing configurations select the same dnd-extraction profile and Notarius pipeline; the testing overlay changes only Scriptorium profiles, so a real testing run may invoke Notarius. The integration suite performs offline configuration inspection only.

Inspecting configuration

The following native Narratio commands resolve configuration without running transcription or requesting a model provider. Select a deployed campaign for the party-driven character family:

sudo -u narratio narratio config validate \
  --config /usr/local/etc/narratio/pipeline.yml --campaign centaurs
sudo -u narratio narratio config validate \
  --config /usr/local/etc/narratio/pipeline.yml --campaign centaurs --profile testing
sudo -u narratio narratio config artifacts \
  --config /usr/local/etc/narratio/pipeline.yml --campaign centaurs
sudo -u narratio narratio config diff default testing \
  --config /usr/local/etc/narratio/pipeline.yml --campaign centaurs

The first two commands validate production and testing resolution. Artifact inspection shows enabled sources, inferred dependencies, and generated family members; the diff shows the overlay's profile selections without modifying managed files.

Storage and publishing, operator selection and group-membership management, scheduling, and end-to-end external execution remain deferred.

Shared execution filesystem

/var/lib/narratio, /var/spool/narratio, /var/cache/narratio, and /var/cache/notarius are narratio:narratio mode 2775 setgid directories. Their access and default ACLs retain owner and group write access plus world read/traverse access for newly created content. The pipeline may run as narratio or as a human account already in the selected runtime group; the production role neither selects people nor manages their group membership. For example, a consumer play can manage its selected operator separately:

- name: Add the selected operator to the pipeline group
  become: true
  ansible.builtin.user:
    name: "{{ pipeline_operator }}"
    groups:
      - "{{ dnd_pipeline_runtime_group }}"
    append: true

Configuration, transcripts, caches, generated artifacts, campaign data, prompts, and logs are non-secret D&D content. Credentials use the restricted /usr/local/etc/narratio/secrets subtree, owned by the selected runtime user and group with mode 0750; managed files use mode 0640. Runtime-group membership authorizes use of these shared credentials, while the subtree grants no world access. Ordinary configuration remains world-readable and contains only reference names.

Managed credentials

dnd_pipeline_secrets defaults to {}. Its keys must be valid environment variable names, and each string value is managed as the exact named credential file. Omitted names are unmanaged: the role neither mirrors nor purges the directory. Narratio loads this conventional sibling directory before configuration resolution; an already-set process environment value takes precedence. The role adds no wrapper, service, or parallel credential loader.

Keep values in encrypted inventory, for example with Ansible Vault; Vault is a consumer workflow, not role functionality:

dnd_pipeline_secrets:
  AUDITA_LLM_API_KEY: "{{ vault_dnd_audita_llm_api_key }}"
  OPENROUTER_API_KEY: "{{ vault_dnd_openrouter_api_key }}"

Scriptorium profiles continue to own their api_key_env selection. To supply that credential through the suite, add a dnd_pipeline_secrets entry whose name matches the selected profile's api_key_env. Narratio's secrets bootstrap loads the value, and its existing Scriptorium adapter forwards only the profile-selected credential.

Validation

tests/integration installs the pinned Git dependencies and collection into private temporary paths, runs syntax and production-profile lint checks, then applies the suite with a local syntactically valid WhisperX URL and explicit immutable file:// asset inputs. It uses native application smoke/configuration commands, validates Notarius's imported pipeline and effective cache policy, and validates Narratio for both deployed campaigns and the testing overlay. It inspects enabled Notarius wiring through Narratio's native effective configuration, validates the same imported Notarius pipeline as a temporary existing-group-member fixture, exercises representative shared cache access across the service and fixture identities, and confirms that nobody can read ordinary configuration. It also composes an alternate pair of version-5 pipeline maps through the public interface and requires clean repeats for the baseline and override cases. Cleanup reapplies the asset-enabled baseline suite and removes only the fixture account, its named test content, and the driver's private temporary directory.
