Configuration Reference

Purpose

Narratio resolves three YAML documents:

• pipeline.yml: pipeline/runtime settings
• campaign.yml: campaign identity and stable input defaults
• session.yml: session identity, metadata, and audio source selection

Discovery and Selection

pipeline.yml

When --config is omitted, search order is:

1. /usr/local/etc/narratio/pipeline.yml
2. /etc/narratio/pipeline.yml

campaign.yml

Selection rules:

• if --campaign-file is set, use that path;
• else if --campaign <id> is set, use {pipeline.campaigns.root}/{id}/campaign.yml;
• else use {pipeline.campaigns.root}/{pipeline.campaigns.default_campaign_id}/campaign.yml.

session.yml

When --session is omitted, local search order is:

1. /usr/local/etc/narratio/session.yml
2. /etc/narratio/session.yml

If local session discovery fails and a session_id is known, Narratio attempts remote session loading from:

• {root_prefix}/campaigns/{campaign}/sessions/{session_id}/session.yml

using configured object storage.

The downloaded remote session file is command-scoped: Narratio removes it after the command finishes and records only the remote object provenance alongside the durable copied session input.

Identity segments

Campaign IDs (campaign_id and default_campaign_id), session IDs, previous session IDs, and Narratio run IDs are opaque portable segments. They must use only ASCII letters, digits, ., _, and -; empty values, ./.., path separators, drive forms, whitespace, control characters, and non-ASCII text are rejected. Narratio does not trim or rewrite these values. Existing manifests or remote state with an unsafe legacy identity must be migrated before use.

Validation and Merge Rules

• YAML decode is strict (KnownFields(true)) and accepts exactly one document: unknown fields or trailing documents fail load.
• Configured timeout and retry-delay durations must be positive. An omitted artifact timeout continues to inherit its configured Scriptorium timeout.
• Session files must be concrete; unresolved {{ ... }} placeholders fail load.
• Pipeline defaults are applied before validation.
• Campaign and session identities must agree.
• Stable files (speakers_file, autocorrect_file, glossary_file, players_file, party_file) resolve from session overrides when provided, otherwise from campaign defaults.
• Exactly one audio mode must be configured in session input:
  • local (audio_dir or audio_files), or
  • S3 (audio_s3.prefix).

Minimal Working Configuration

pipeline.yml

campaigns:
  root: /usr/local/share/narratio/campaigns
  default_campaign_id: sample-campaign
whisperx:
  transcribe_url: https://transcription.example.com/transcribe

campaign.yml

campaign_id: sample-campaign
inputs:
  speakers_file: ./speakers.yml
  autocorrect_file: ./autocorrect.yml
  glossary_file: ./glossary.yml
  players_file: ./players.yml
  party_file: ./party.yml

session.yml (local audio)

session_id: 2026-05-03
inputs:
  audio_dir: ./audio

Secrets Handling

• Do not place raw secrets in YAML.
• Use env var names in config (for example pipeline.audita.llm_api_key_env).
• Optionally load credential files from pipeline.secrets.env_dir. Each valid environment-variable filename supplies one value; trailing CR/LF is removed.
• An existing process environment value takes precedence over a credential file.
• Credential directories and files must not be symlinks and must be regular, bounded files (at most 8 KiB per value). On POSIX, provision the directory with no group/other access (normally 0700) and files with no group/other access (normally 0600).
• Commands that need storage/auth load filesystem secrets before constructing adapters.

Publish Configuration Summary

Publish rules live under pipeline.publish.

publish:
  enabled: true
  upload_run: true
  outputs:
    - source: narratio.transcript.final_trimmed
      dest: transcripts/final.trimmed.json
      required: true
    - source: narratio.transcript.final_markdown
      dest: transcripts/final.md
      required: true
    - source: narratio.transcript.final_trimmed_markdown
      dest: transcripts/final.trimmed.md
      required: true
    - source: narratio.artifact.session_recap
      dest: artifacts/session_recap.md
      required: true
  locks:
    - source: narratio.artifact.session_recap
      reason: manual post-publish edits

Rules:

• outputs[].source is required.
• outputs[].dest may be omitted when derivable from source.
• extraction sources require an explicit outputs[].dest and publish only when a rule names that source; the Notarius index and complete bundle are not publish sources.
• outputs[].required defaults to true.
• static locks (pipeline.publish.locks) merge with remote locks ({session_prefix}/locks.yml), with static locks taking precedence on duplicates.

Notarius Output Entries

For each pipeline.notarius.outputs.<name>:

Field	Type	Required	Rule
lane_id	string	Yes	unique Notarius lane ID
media_type	string	Yes	exact accepted descriptor media type
schema_id	string	Yes	exact accepted descriptor schema ID
schema_version	string	Yes	exact accepted descriptor schema version
module_key	string	No	exact accepted module key when set

Output names must match ^[a-z][a-z0-9_]*$ and become selectable sources named narratio.extraction.<name>. Lane IDs must be unique. Every declared output is required from a successful Notarius result; a missing, rejected, duplicate, or contract-incompatible lane fails extraction. See the complete maintained example for the current ten-lane D&D mapping and the Notarius contract for compatibility ownership.

Scriptorium Artifact Entries

For each pipeline.scriptorium.artifacts.<name>:

Field	Type	Required	Rule
enabled	bool	No	false if omitted
depends_on[]	list[string]	No	must reference configured artifact keys; no self-reference; enabled graph must be acyclic
render_debug	bool	No	per-artifact override
prompt_id	string	Conditional	required when artifact is enabled
profile_id	string	No	empty
output_path	string	Conditional	required when enabled; also required when referenced by publish/output/input rules
timeout	duration	No	artifact override
inputs	map	No	input key names must be non-empty
vars	map	No	values must be string or bool; session_id is reserved and overwritten by Narratio

Narratio adds session_id=narratio-session-<session_id> to every Scriptorium request for sticky upstream LLM routing. If an artifact config sets vars.session_id, Narratio replaces that value before invoking Scriptorium. Use a different variable name if a prompt needs the raw Narratio session ID as content.

For each artifact input pipeline.scriptorium.artifacts.<name>.inputs.<input_name>:

Field	Type	Required	Rule
source	string	Yes	built-in runtime source, prepared input source, narratio.extraction.<name>, narratio.artifact.<name>, or narratio.previous_session.artifact.<name>
required	bool	No	optional input requirement

artifact and path are obsolete and rejected by strict configuration loading. Use the canonical source identifier to select the input; Narratio does not provide adapter-specific input passthrough fields.

Notifications

Narratio currently supports only notification.mode: noop, which is also the default when the section is omitted. The notify stage performs no delivery in this mode. Backend, recipient, timeout, and other provider settings are rejected by strict configuration loading until Narratio has a provider integration.

Campaign

Field	Type	Required	Notes
campaign_id	string	Yes	canonical opaque campaign identity
session_template_file	string	No	used by session init when set
inputs.speakers_file	string	Yes	stable input default
inputs.autocorrect_file	string	Yes	stable input default
inputs.glossary_file	string	Yes	stable input default
inputs.players_file	string	Yes	stable input default
inputs.party_file	string	Yes	stable input default

Session

Field	Type	Required in session file	Notes
session_id	string	Yes	opaque identity; must match CLI session target when provided
previous_session_id	string	No	opaque identity; must not equal session_id
campaign	string	No	opaque identity; filled from campaign_id during resolve if omitted
date	string	No	metadata
title	string	No	metadata
inputs.speakers_file	string	No	overrides campaign stable input
inputs.autocorrect_file	string	No	overrides campaign stable input
inputs.glossary_file	string	No	overrides campaign stable input
inputs.players_file	string	No	overrides campaign stable input
inputs.party_file	string	No	overrides campaign stable input
inputs.audio_dir	string	Conditional	local audio mode
inputs.audio_files[]	list[string]	Conditional	local audio mode
inputs.audio_s3.prefix	string	Conditional	S3 audio mode

Audio rules:

• configure local mode (audio_dir or audio_files) or S3 mode (audio_s3.prefix), not both.
• audio_s3 requires pipeline.storage.backend: s3 and a configured S3 bucket.

Storage backend selection

local is the default and disables remote object-store operations. Configure s3 explicitly before supplying storage.s3; a populated S3 block does not select a backend on its own. Unknown backend names and an S3 block paired with local are rejected during configuration validation.

Previous-session expectation

previous_session_id is optional in a session file. When a command supplies --previous-session-id, however, the session file must contain the same value; an omitted or different value is rejected before the command performs work.

Maintained Examples

See the maintained examples index for complete pipeline, campaign, session, template, and input fixtures. Keep complete copyable files there rather than duplicating them in this reference.
