-# ansible-role-dnd-pipeline
+# rakestraw.dnd_pipeline
 
-An Ansible role to install the full D&D production pipeline (Narratio, Seriatim, Audita, Notarius, and Scriptorium, plus supporting assets).
\ No newline at end of file
+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`.
+
+## Installation
+
+Install the role dependencies and their collection before applying this role:
+
+```sh
+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`. This standalone role is
+named `rakestraw.dnd_pipeline`; a later collection release will expose it as
+`rakestraw.dnd.pipeline`.
+
+```yaml
+---
+- name: Install the D&D pipeline foundation
+  hosts: pipeline_hosts
+  gather_facts: true
+  roles:
+    - role: rakestraw.dnd_pipeline
+      vars:
+        dnd_pipeline_whisperx_transcribe_url: https://whisperx.example/transcribe
+```
+
+## 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` | `v2.0.0` |
+| `dnd_pipeline_notarius_version` | `v0.6.0` |
+| `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` |
+
+The common dependency-management switch controls whether every application
+role installs 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.
+
+Narratio receives the standard Seriatim, Audita, Notarius, and Scriptorium
+binary and configuration paths managed by the composed roles. Notarius is
+installed but remains disabled in Narratio until a later feature supplies a
+Notarius pipeline. Campaign content, prompt content, operator policy, and
+secret delivery are intentionally deferred.
+
+## Validation
+
+`tests/integration` installs the pinned Git dependencies and collection into
+private temporary paths, runs syntax and production-profile lint checks, then
+applies the baseline suite with a local syntactically valid WhisperX URL. It
+uses native application smoke/configuration commands, validates Narratio's
+assembled configuration as the Narratio account, and requires an immediate
+clean repeat. Cleanup reapplies the baseline suite and removes only the
+driver's private temporary directory.
+
+An Ansible role to install the full D&D production pipeline (Narratio, Seriatim, Audita, Notarius, and Scriptorium, plus supporting assets).
