Configuration

This is the canonical reference for implemented Notarius configuration.

Notarius reads YAML config files with version: 2. File config is applied over built-in defaults, then environment overrides are applied.

Discovery

Commands that accept --config load configuration in this order:

1. the --config path, when provided;
2. NOTARIUS_CONFIG, when set to a non-empty path;
3. /usr/local/etc/notarius/config.yml.

If none is available, the command fails with a config file not found error.

Minimal Example

version: 2
pipelines:
  dnd-session:
    input: seriatim
    references:
      party: ./dnd-spells-roster.txt
      glossary: ./dnd-spells-glossary.txt
    chunk:
      module: generic
      options:
        max_units: 50
    artifacts:
      spells:
        extract: dnd/spells

The maintained fixture is examples/dnd-spells.config.yml.

Top-Level Fields

• version: required. The only supported value is 2.
• scriptorium: optional Scriptorium profile source settings.
• pipelines: optional map of pipeline IDs to pipeline definitions.
• concurrency: optional global concurrency settings.
• diagnostics: optional diagnostics settings.

Unknown YAML fields are rejected. The removed top-level llm_profiles field is rejected; execution profiles now come from Scriptorium.

Defaults

Built-in defaults:

concurrency:
  total_llm: 1
diagnostics:
  work_dir: /tmp/notarius
  retention: auto

No pipelines are built in. A run requires a configured pipeline.

If scriptorium is omitted, Notarius uses Scriptorium's built-in profile catalog. Prompt definitions may also name default profile IDs. The current D&D scene and spell prompts use Scriptorium prompt defaults when a module binding does not set llm_profile.

Scriptorium Profiles

scriptorium fields:

• profile_dir: optional directory containing Scriptorium profile YAML files.
• profile_file: optional Scriptorium profile YAML file.

profile_dir and profile_file are mutually exclusive. Custom profiles overlay Scriptorium built-in profiles by profile ID.

Scriptorium profile files use Scriptorium's profile schema. A minimal profile looks like:

id: local-fast
endpoint: http://127.0.0.1:8080/v1
model: your-model
api_key_env: SCRIPTORIUM_API_KEY
timeout_seconds: 180

Notarius does not accept raw API keys in Notarius config. For file-backed Scriptorium profiles, store the environment variable name in api_key_env and set that variable in the run environment. Scriptorium rejects raw api_key fields in profile YAML.

Environment Overrides

These environment variables are applied after the config file:

• NOTARIUS_CONFIG: config discovery path.
• NOTARIUS_TOTAL_LLM_CONCURRENCY: integer global LLM concurrency.
• NOTARIUS_WORK_DIR: diagnostics work directory.
• NOTARIUS_DIAGNOSTICS_RETENTION: diagnostics retention mode.

Integer environment values must parse as base-10 integers.

The removed NOTARIUS_LLM_DEFAULT_* variables are not read. Configure provider endpoint, model, and credential environment variable names through Scriptorium profiles.

Pipelines

A pipeline defines the fixed Notarius workflow:

input -> chunk -> extract -> merge -> normalize -> output

Pipeline fields:

• input: required module binding.
• chunk: optional module binding. Default module is generic.
• artifacts: required for pipeline resolution. It maps artifact lane IDs to lane definitions.
• output: optional module binding. Default module is json.
• references: optional map of reference slot names to reference paths. These bindings are defaults for eligible pipeline targets that declare the matching slot.

Artifact lane fields:

• extract: required module binding.
• merge: optional module binding. Default module is appendorder.
• normalize: optional module binding. Default module is noop.
• validators: optional list of module bindings. The production CLI currently does not register validator modules.
• references: optional compatibility alias for extractor reference bindings. Lane bindings override pipeline-level bindings for the same slot.

notarius run and notarius config validate --pipeline resolve the pipeline against the production module catalog and fail fast for unknown or incompatible module keys.

Reference bindings are validated against reference slots declared by eligible chunk, extract, merge, and normalize targets during pipeline resolution. Required slots must be bound after config defaults, target-local references, lane-level compatibility bindings, and run-time --reference or --without-reference overrides are applied. Config-relative paths are resolved relative to the config file; CLI reference paths are resolved relative to the current working directory. Materialized bound files must be UTF-8 text. Materialized reference provenance is recorded for chunk, extractor, merger, and normalizer targets, and runtime reference content is passed to the target that declares the slot. Reference media types are inferred from file extensions, recorded as canonical base media types, and checked only when a module declares AcceptedMediaTypes; unknown extensions are recorded as application/octet-stream. Reference content is not written to diagnostics, logs, errors, or manifests.

Pipeline-level references are defaults. They are valid when at least one eligible target in the full configured pipeline declares the slot, including chunk, extractor, merger, and normalizer targets. During a run, they apply only to the selected targets that declare the slot:

pipelines:
  dnd-session:
    input: seriatim
    references:
      players: ./campaign/players.txt
      party: ./campaign/party-roster.txt
      glossary: ./campaign/glossary.txt
    artifacts:
      spells:
        extract: dnd/spells

Extractor binding references are the canonical lane-local location. The legacy lane-level references field remains supported as an alias; when both bind the same slot, extract.references wins:

pipelines:
  dnd-session:
    input: seriatim
    references:
      glossary: ./campaign/glossary.txt
    artifacts:
      spells:
        references:
          roster: ./campaign/legacy-roster.txt
        extract:
          module: dnd/spells
          references:
            party: ./campaign/session-party.txt

chunk.references, merge.references, and normalize.references are accepted in object-form bindings. They override pipeline-level defaults for slots declared by that target module. Extractor-local references apply only to the extractor, merger-local references apply only to the merger, and normalizer-local references apply only to the normalizer.

Target-local reference fields use the same map shape at:

• pipelines.<id>.chunk.references
• pipelines.<id>.artifacts.<lane>.extract.references
• pipelines.<id>.artifacts.<lane>.merge.references
• pipelines.<id>.artifacts.<lane>.normalize.references

Each binding is valid only when that target module declares the slot.

Module Bindings

Every module binding may use shorthand:

input: seriatim

or object form:

chunk:
  module: dnd/scenes
  llm_profile: local-fast

Binding fields:

• module: module key.
• llm_profile: optional Scriptorium profile ID. Empty or omitted lets the Scriptorium prompt default select the profile.
• retries: non-negative retry count for extra runtime attempts after the first attempt. The runner applies retries to chunk, extract, merge, and normalize bindings.
• options: optional module-specific settings.
• references: optional reference bindings. Supported only for chunk, extract, merge, and normalize bindings. input, validator, and output bindings reject this field during validation.

The --llm-profile run flag overrides every effective LLM-capable module binding to use one Scriptorium profile ID: chunk, every selected lane extract, merge, and normalize binding.

Implemented Production Modules

Slot	Key	Notes
input	seriatim	Reads Seriatim transcript JSON.
chunk	generic	Splits source units into ordered chunks.
chunk	dnd/scenes	Uses an LLM to split transcript source units into D&D scenes.
extract	dnd/spells	Extracts D&D spell raw outputs.
merge	appendorder	Merges JSON raw extract outputs in chunk order.
normalize	noop	Passes merged raw outputs through unchanged.
output	json	Produces JSON output files for normalized application/json lanes.

The generic chunker accepts:

• max_units: positive integer, default 50;
• overlap_units: non-negative integer, default 0, and must be less than max_units.

The dnd/scenes chunker requires transcript source capabilities, calls the configured structured LLM runtime, and does not accept module options. It declares optional players, party, and glossary references for scene disambiguation, and accepts roster as a deprecated compatibility alias for party.

The dnd/spells extractor declares optional reference slots:

• players
• party
• glossary
• roster as a deprecated compatibility alias for party

Both modules accept UTF-8 plain text, Markdown, YAML, or JSON reference files. The extractor uses references only as supporting disambiguation material; spell casts still must be present in the source transcript.

Diagnostics

diagnostics fields:

• work_dir: directory for per-run diagnostics. Default: /tmp/notarius.
• retention: auto, always, or never. Empty uses auto.

auto retains diagnostics for failed runs and successful runs with warnings. always retains diagnostics for every run. never removes diagnostics for successful runs without regard to warnings; failed runs are retained.

The --diagnostics-dir run flag overrides diagnostics.work_dir for that invocation.

Validation

Configuration validation checks:

• supported config version and known YAML fields;
• mutually exclusive scriptorium.profile_dir and scriptorium.profile_file;
• non-empty, non-duplicated IDs after trimming;
• positive global LLM concurrency;
• supported diagnostics retention and non-empty work directory;
• stale removed fields such as llm_profiles.

Pipeline resolution additionally checks:

• the pipeline ID exists;
• at least one artifact lane is declared and selected;
• selected lanes exist when --only is used;
• required module keys are present;
• module keys are registered for the expected slot;
• module capability requirements are satisfied;
• bound reference slots are declared by selected chunk, extractor, merger, or normalizer targets;
• required reference slots are bound for selected targets.
