-# OpenAI-Compatible Structured Output
-
-This document describes the external LLM provider contract implemented by the
-production Notarius LLM client.
-
-## Provider
-
-- Provider key: `openai-compatible`
-- HTTP method: `POST`
-- Endpoint: `<base_url>/chat/completions`
-- Request body: JSON
-- Response mode: chat completions with structured JSON schema output
-
-`base_url` is trimmed of trailing slashes before `/chat/completions` is
-appended. Configure provider settings in [Configuration](../config.md).
-
-## Request
-
-The client sends a JSON object with:
-
-```json
-{
-  "model": "configured-model",
-  "messages": [
-    {
-      "role": "system",
-      "content": "..."
-    },
-    {
-      "role": "user",
-      "content": "..."
-    }

-    "type": "json_schema",

-      "name": "schema_name",
-      "strict": true,
-      "schema": {}
-    }
-  }
-}
-```
-
-Implemented request behavior:
-
-- `model` comes from the structured completion request when set, otherwise from
-  the configured LLM profile.
-- `messages` must be non-empty; each role and content must be non-empty after
-  trimming.
-- `response_format.type` is always `json_schema`.
-- `response_format.json_schema.strict` is always `true`.
-- `response_format.json_schema.name` and `schema` come from the extractor or
-  validator making the call.
-
-If an API key is configured, the client sends:
-
-```text
-Authorization: Bearer <api-key>
-```
-
-The client always sends `Content-Type: application/json`.
-
-## Response
-
-The client expects a JSON response with at least one choice:
-
-```json
-{
-  "model": "provider-model",
-  "choices": [
-    {
-      "message": {
-        "content": "{\"field\":\"value\"}"
-      }
-    }
-  ],
-  "usage": {
-    "prompt_tokens": 10,
-    "completion_tokens": 5,
-    "total_tokens": 15
-  }
-}
-```
-
-`choices[0].message.content` may be either:
-
-- a JSON string whose contents are valid JSON; or
-- raw JSON.
-
-The decoded content is unmarshaled into the caller-provided structured output
-target. If `usage` is present, prompt, completion, and total token counts are
-copied into the completion response.
-
-## Errors And Retries
-
-The client validates base URL, model, response schema name, response schema
-JSON, messages, and output target before or during the call.
-
-Retryable failures:
-
-- HTTP request failure;
-- response body read failure;
-- HTTP `429`;
-- HTTP `5xx`;
-- malformed provider response envelope;
-- missing choices;
-- missing, empty, or invalid assistant JSON content;
-- structured-output decode failure.
-
-Non-retryable provider status codes include non-`429` `4xx` responses.
-
-Provider error bodies are parsed for `error.message` or `message` when present.
-Configured API key values and bearer-token values are redacted from returned
-provider errors.
-
-## Timeouts And Concurrency
-
-The configured profile timeout is applied per provider request when greater
-than zero. Context cancellation is respected.
-
-The production CLI wraps the provider client with the LLM scheduler. Effective
-concurrency is described in [LLM runtime internals](../internal/llm.md).
-
-## Limits
-
-This contract documents only the fields the implemented client sends and reads.
-Provider-specific extensions are ignored unless they affect those fields.

-- Keep Scriptorium types out of chunk, extract, and normalize module contracts.
+Remaining product and operational ideas belong in [Future Work](future.md).
-  Module-facing requests should use Notarius-owned contract types.
-- Keep provider plumbing behind `internal/framework/llm` and CLI construction.
-- Keep module-owned prompt intent, prompt IDs, response schemas, validators, and
-  source-reference validation with the relevant modules.
-- Keep raw input material, raw references, raw prompts, raw schemas, and API
-  keys out of manifests and default diagnostics.
-- Treat the original source input and large references as prompt input
-  materials. They may be passed to Scriptorium as inline/file inputs, but should
-  not be copied into durable provenance.
-- Use Scriptorium profile configuration directly. Do not keep Notarius'
-  `llm_profiles` schema as a second profile system.
-- Use Scriptorium structured-output execution and validation behavior for
-  production calls. Notarius should still unmarshal successful structured JSON
-  into module-owned response structs and run module-owned deterministic
-  validation afterward.
-
-## Stage 1: Dependency And API Grounding
-
-Goal: add the Scriptorium dependency and establish the exact public API surface
-used by the rest of the implementation.
-
-Work:
-
-- Add `gitea.maximumdirect.net/eric/scriptorium` to `go.mod` with `go get`.
-- Inspect the installed package with `go doc` or source reads before coding the
-  adapter. Confirm names and fields for:
-  - `NewEngine`;
-  - `Config`;
-  - `WithPromptFS`, `WithPromptFile`, or equivalent prompt source options;
-  - `WithProfileFile`, `WithProfileFS`, profile directory config, and built-in
-    profile behavior;
-  - `WithSchemaFS` or equivalent schema source options;
-  - `RunRequest`, including prompt ID, prompt version, profile ID, inputs,
-    variables, metadata, direct API key, and validation override fields;
-  - `RunResult`, including raw output, output artifact, validation status,
-    prompt/profile/model metadata, usage, and timings;
-  - public sentinel errors.
-- Add a short internal implementation note as a code comment only where needed;
-  do not add user-facing docs in this stage except if a package-level test
-  helper needs explanation.
-
-Acceptance checks:
-
-- `go test ./internal/framework/llm`
-- `go test ./internal/cli`
-- `go test ./...`
-
-## Stage 2: Prompt Input Materials And Session IDs
-
-Goal: make raw source input and references available to module prompt execution
-without storing large content in manifests or default diagnostics.
-
-Work:
-
-- Add Notarius-owned contract types under `internal/framework/contracts`:
-  - `LLMInputMaterial` with at least `Name`, `MediaType`, `Content`, `Digest`,
-    `OriginURI`, and `SizeBytes`;
-  - a helper-friendly collection type, such as `LLMInputSet`, if useful.
-- Add prompt-execution fields to `StructuredCompletionRequest`:
-  - `PromptID`;
-  - `PromptVersion`;
-  - `ProfileID` or reuse the request `LLMProfile` value when called from stage
-    requests;
-  - `SessionID`;
-  - `Inputs map[string]LLMInputMaterial`;
-  - `Vars map[string]any`.
-- Keep or remove the old `Messages`, `Model`, `ResponseSchemaName`, and
-  `ResponseSchema` fields according to what makes the cutover cleanest. The
-  final production path must not require modules to pass rendered messages or
-  raw schema JSON directly to the provider adapter.
-- Add `SourceInput contracts.LLMInputMaterial` and `SessionID string` to
-  `ChunkRequest`, `ExtractionRequest`, and `NormalizeRequest`.
-- Add `SessionID string` to `pipeline.RunInput`.
-- In `pipeline.Run`, build a source input material from `RunInput.RawInput` and
-  `RunInput.Path`:
-  - preserve the bytes exactly;
-  - infer media type from the input path extension, using `application/json`
-    for `.json` and a deterministic fallback for unknown extensions;
-  - compute a SHA-256 digest;
-  - use a file URI or path-derived origin URI;
-  - do not put the bytes in manifest metadata.
-- Pass the same source input material and session ID to chunk, extract, and
-  normalize requests.
-- Reuse existing materialized `ReferenceSet` content for reference prompt
-  inputs. Do not introduce a second file-reading path for references.
-- Add CLI support for `--session-id <id>` on `notarius run`.
-  - Empty means use a deterministic default derived from the parsed source
-    document ID.
-  - The deterministic default must be stable across runs over the same parsed
-    source document.
-  - The explicit value should be trimmed and rejected if empty after trimming.
-- Because the default depends on the parsed source document, compute and attach
-  the final session ID inside the runner after input parsing, or return enough
-  information from parsing for the CLI to resolve it before LLM calls.
-- Record the non-secret session ID in run metadata or manifest metadata, but
-  never record raw prompt content.
-
-Acceptance tests:
-
-- Contract tests proving `LLMInputMaterial.Content` is defensively copied where
-  relevant and omitted from JSON.
-- Pipeline tests proving chunk, extract, and normalize requests receive the same
-  source input bytes and session ID.
-- CLI tests for `--session-id`, including explicit value, missing value,
-  trimming, and default behavior.
-- Redaction/diagnostics tests proving raw source bytes and reference content do
-  not appear in manifests or default diagnostics.
-
-Focused checks:
-
-- `go test ./internal/framework/contracts`
-- `go test ./internal/framework/pipeline`
-- `go test ./internal/cli`
-
-## Stage 3: Configuration Hard Cutover To Scriptorium Profiles
-
-Goal: replace Notarius' local LLM profile schema with Scriptorium profile
-selection and profile sources.
-
-Work:
-
-- Bump the Notarius file config version because this is an incompatible config
-  schema change.
-- Remove the top-level `llm_profiles` file-config schema and the local
-  `config.LLMProfile` model.
-- Add a top-level Scriptorium config block. Use this shape unless Scriptorium's
-  installed API requires a small naming adjustment:
-
-  ```yaml
-  scriptorium:
-    profile_dir: ./profiles
-    profile_file: ./profiles.yml
-  ```
-
-- Treat `profile_dir` and `profile_file` as mutually exclusive in Notarius
-  config validation. Built-in Scriptorium profiles remain available when neither
-  is set.
-- Keep existing module binding field name `llm_profile`; it now names a
-  Scriptorium profile ID.
-- Stop forcing empty module `llm_profile` bindings to
-  `pipeline.DefaultLLMProfile`. Empty means "use the Scriptorium prompt's
-  `default_profile`."
-- Keep `--llm-profile` as a run-level operational override. It should set the
-  same explicit Scriptorium profile ID for every LLM-eligible selected target.
-- Remove `OpenAICompatibleClientConfig` construction from `internal/core/config`.
-- Remove local OpenAI-compatible provider validation from config validation.
-- Add config validation for:
-  - config version;
-  - mutually exclusive `scriptorium.profile_dir` and
-    `scriptorium.profile_file`;
-  - non-empty profile source paths when fields are present;
-  - non-empty explicit `llm_profile` strings after trimming.
-- Add CLI/config validation that uses Scriptorium profile loading to reject
-  unknown explicit profile IDs when possible. Prompt-default profile failures
-  may surface during Scriptorium prepare/run if Scriptorium owns that lookup.
-- Remove or replace environment override behavior tied to
-  `NOTARIUS_LLM_DEFAULT_*`. Secrets should come from Scriptorium profile
-  `api_key_env` values or direct request-scoped Scriptorium behavior.
-- Update redacted effective config behavior for the new Scriptorium config
-  shape.
-
-Acceptance tests:
-
-- Config parsing accepts `scriptorium.profile_dir`.
-- Config parsing accepts `scriptorium.profile_file`.
-- Config validation rejects both fields set at once.
-- Config validation rejects stale `llm_profiles`.
-- Existing pipeline bindings with explicit `llm_profile` resolve to trimmed
-  Scriptorium profile IDs.
-- Empty `llm_profile` remains empty through resolution unless `--llm-profile`
-  is supplied.
-- CLI config validation fails cleanly for an unknown explicit profile ID.
-- Redacted config diagnostics do not contain raw API keys.
-
-Focused checks:
-
-- `go test ./internal/core/config`
-- `go test ./internal/cli`
-
-## Stage 4: Scriptorium Prompt And Schema Assets
-
-Goal: move production LLM prompts and schemas to Scriptorium-compatible assets
-while preserving module ownership.
-
-Work:
-
-- Create a prompt/schema asset registration mechanism that does not put
-  D&D-specific prompt content in framework packages.
-  - Recommended shape: add a small prompt-asset registry in
-    `internal/framework/llm` or a sibling framework package that can collect
-    `fs.FS` roots for Scriptorium prompt and schema sources.
-  - Production module packages should register their own Scriptorium prompt and
-    schema assets through production catalog/registry wiring in `internal/cli`.
-  - Shared D&D prompt assets may live in a D&D-specific module package such as
-    `internal/modules/dnd/promptassets`; they must not live in `internal/core`
-    or source-agnostic framework packages.
-- Add shared D&D prompt assets:
-  - stable shared system message, if needed;
-  - stable cacheable transcript user message:
-
-    ```text
-    A transcript of a Dungeons & Dragons gameplay session is provided below.
-
-    {{ input "transcript" }}
-    ```
-
-  - stable cacheable reference/context message templates for roster, glossary,
-    previous recap, or other large references used by current D&D modules.
-- Convert `dnd/scenes` to a Scriptorium prompt definition:
-  - prompt ID: `dnd.scenes`;
-  - prompt version: current module prompt version;
-  - input `transcript`, required, `application/json`;
-  - messages ordered for cache reuse: shared system, shared transcript user
-    message with cache control, scene task, scene instructions;
-  - output JSON schema path pointing at the existing scene schema asset;
-  - schema IDs/names/versions remain module-owned and manifest-safe.
-- Convert `dnd/spells` to a Scriptorium prompt definition:
-  - prompt ID: `dnd.spells`;
-  - prompt version: current module prompt version;
-  - input `transcript`, required, `application/json`;
-  - optional inputs for `roster` and `glossary`;
-  - messages ordered for cache reuse: shared system, shared transcript user
-    message with cache control, optional/reference context message with cache
-    control, spell task, spell instructions;
-  - output JSON schema path pointing at the existing spell schema asset.
-- For optional references, pass empty inline input material when the slot is
-  unbound unless Scriptorium's template/input semantics support missing
-  optional inputs cleanly. Do not let optional missing references make prompt
-  rendering fail.
-- For multiple reference items in one slot, concatenate deterministically with
-  stable headings that include only non-secret provenance, then pass the result
-  as that prompt input. Existing single-item slots should keep their current
-  behavior.
-- Replace current prompt hash metadata with hashes derived from the
-  Scriptorium prompt definition plus message assets, or with Scriptorium
-  prepared-run prompt metadata if it is available without raw prompt content.
-- Preserve existing manifest metadata keys where practical:
-  - `prompt_id`;
-  - `prompt_version`;
-  - `prompt_sha256`;
-  - `response_schema_key`;
-  - `response_schema_id`;
-  - `response_schema_name`;
-  - `response_schema_version`;
-  - `response_schema_sha256`.
-
-Acceptance tests:
-
-- Prompt asset loading fails fast for missing prompt files or schemas.
-- `dnd/scenes` prepared prompt contains separate transcript and task messages.
-- `dnd/spells` prepared prompt contains separate transcript, reference, and
-  task messages.
-- The transcript message body is byte-identical to the expected shared template
-  plus original Seriatim JSON bytes.
-- Reference prompt input rendering is deterministic.
-- Prompt/schema diagnostics omit raw prompt text, raw transcript bytes, raw
-  reference content, and raw schema JSON.
-
-Focused checks:
-
-- `go test ./internal/framework/llm`
-- `go test ./internal/modules/chunk/dnd/scenes`
-- `go test ./internal/modules/extract/dnd/spells`
-
-## Stage 5: Scriptorium-Backed LLM Runtime
-
-Goal: implement the production `StructuredLLMClient` using Scriptorium.
-
-Work:
-
-- Add a Scriptorium-backed client under `internal/framework/llm`.
-- Its constructor should accept:
-  - Scriptorium profile source settings from effective Notarius config;
-  - registered prompt/schema assets;
-  - request timeout or HTTP client settings only if still owned by Notarius
-    after the profile cutover;
-  - optional Scriptorium engine options for tests.
-- Implement `CompleteStructured(ctx, req, out)` by:
-  - validating `out` is a non-nil pointer;
-  - validating `req.PromptID` is non-empty;
-  - converting Notarius `LLMInputMaterial` values to Scriptorium artifact refs;
-  - adding `session_id` to Scriptorium request vars when non-empty;
-  - passing explicit profile ID only when the module binding or CLI override
-    supplied one;
-  - passing no raw API key unless a deliberate request-scoped secret path is
-    implemented;
-  - calling Scriptorium `Run`;
-  - converting final validation failure into a Notarius error;
-  - unmarshaling successful structured JSON into `out`;
-  - returning `StructuredCompletionResponse` with raw JSON content, provider,
-    model, profile ID when available, token usage, and non-secret metadata.
-- Add a profile recorder or response accumulator so `RunManifest.LLMProfiles`
-  records the actual Scriptorium profile/provider/model values used during the
-  run.
-  - Do not rely on one precomputed profile ID before pipeline execution.
-  - Deduplicate profile manifest entries deterministically.
-- Keep the existing `Scheduler` and scheduled client wrapper unless Scriptorium
-  provides an equivalent Notarius-approved concurrency mechanism.
-- Ensure all Scriptorium errors are wrapped with context and converted to
-  concise CLI-facing errors. Preserve `errors.Is` checks internally when
-  practical.
-- Apply Notarius secret redaction to errors before writing diagnostics.
-- Remove production construction of `OpenAICompatibleClient`.
-
-Acceptance tests:
-
-- Scriptorium adapter maps Notarius prompt request fields into the expected
-  Scriptorium run request using an injected fake Scriptorium LLM client.
-- Successful structured output unmarshals into the caller target.
-- Scriptorium validation failure returns an error.
-- Provider/runtime failure returns an error with operation context.
-- Context cancellation is respected.
-- Token usage maps into `StructuredCompletionResponse`.
-- Used Scriptorium profile/provider/model metadata appears in the run manifest
-  without secrets.
-- API keys or bearer tokens in synthetic errors are redacted.
-- Scheduler still bounds concurrent Scriptorium-backed calls.
-
-Focused checks:
-
-- `go test ./internal/framework/llm`
-- `go test ./internal/framework/pipeline`
-- `go test ./internal/cli`
-
-## Stage 6: Module Cutover And Legacy Runtime Removal
-
-Goal: update production modules to call the prompt-based contract and remove
-obsolete local prompt/runtime code.
-
-Work:
-
-- Update `dnd/scenes`:
-  - stop rendering local system/user prompt strings;
-  - call `CompleteStructured` with `PromptID`, `PromptVersion`, `SessionID`,
-    `ProfileID` or request LLM profile, `transcript` input material, and any
-    required vars;
-  - keep existing response validation, chunk canonicalization, caveat handling,
-    and manifest metadata policy.
-- Update `dnd/spells`:
-  - stop rendering local system/user prompt strings;
-  - call `CompleteStructured` with `transcript`, optional `roster`, optional
-    `glossary`, session ID, profile ID, and vars;
-  - keep existing spell response validation, source-reference validation, and
-    manifest metadata policy.
-- Update any LLM-backed normalize modules if present. If only noop normalize is
-  present, ensure the contract and tests prove normalizers can receive the same
-  Scriptorium-capable client and prompt inputs.
-- Remove the old `internal/framework/prompt` renderer if no remaining code uses
-  it. If generic tests still need prompt rendering, replace them with
-  Scriptorium prompt asset tests or delete obsolete tests.
-- Remove `internal/framework/llm/openai_compatible_client.go` and its tests
-  after the Scriptorium adapter tests cover replacement behavior.
-- Remove local OpenAI-compatible integration docs after current-behavior docs
-  are updated in Stage 7.
-- Remove stale schema registry helpers only if they are no longer needed for
-  module-owned schema metadata. Keep lightweight schema hashing/loading helpers
-  if modules still use them for manifest metadata.
-
-Acceptance tests:
-
-- `dnd/scenes` fake-client tests assert the module sends prompt ID,
-  transcript input, session ID, and schema/prompt metadata rather than rendered
-  message text.
-- `dnd/spells` fake-client tests assert roster/glossary inputs are passed as
-  inputs and not interpolated locally.
-- Existing malformed LLM response tests still fail as malformed structured
-  output.
-- Existing source-reference validation tests still pass.
-- No production code imports the old prompt renderer or local
-  OpenAI-compatible client.
-
-Focused checks:
-
-- `go test ./internal/modules/chunk/dnd/scenes`
-- `go test ./internal/modules/extract/dnd/spells`
-- If `internal/framework/prompt` is deleted, do not run a package-specific test
-  for it; instead verify with `rg -n "internal/framework/prompt|RenderUserSystem" internal`
-  that no production code still depends on it.
-
-## Stage 7: CLI, Examples, Docs, And Full Validation
-
-Goal: finish user-facing behavior, examples, and canonical docs for the new
-runtime.
-
-Work:
-
-- Update `examples/dnd-spells.config.yml` and any maintained test configs to
-  the new config version and Scriptorium profile source behavior.
-- Update `docs/config.md`:
-  - new config version;
-  - `scriptorium.profile_dir` and `scriptorium.profile_file`;
-  - `llm_profile` now means Scriptorium profile ID;
-  - empty `llm_profile` behavior;
-  - removed `llm_profiles`;
-  - removed `NOTARIUS_LLM_DEFAULT_*` env behavior if removed;
-  - secret-handling policy through Scriptorium profile `api_key_env`.
-- Update `docs/cli.md`:
-  - add `--session-id`;
-  - update `--llm-profile` wording to Scriptorium profile override;
-  - update run examples if needed.
-- Update `docs/internal/llm.md`:
-  - Scriptorium-backed runtime;
-  - prompt asset loading;
-  - input material handling;
-  - scheduling;
-  - structured-output validation;
-  - profile manifest recording;
-  - secret redaction.
-- Update `docs/internal/modules.md`:
-  - module prompt ownership through Scriptorium prompt definitions;
-  - chunk/extract/normalize request input materials and session ID;
-  - D&D scenes/spells prompt metadata.
-- Update `docs/internal/pipeline.md`:
-  - raw input material lifecycle;
-  - reference material lifecycle into prompt inputs;
-  - session ID lifecycle;
-  - actual LLM profile provenance.
-- Update `docs/integrations/json-output.md` for any manifest changes.
-- Remove or rewrite `docs/integrations/openai-compatible.md`. If no local
-  OpenAI-compatible adapter remains, do not document it as current Notarius
-  behavior.
-- Update `docs/troubleshooting.md` for:
-  - Scriptorium profile-not-found;
-  - prompt-not-found;
-  - schema/validation failures;
-  - missing API key env values;
-  - session ID usage if relevant.
-- Update `docs/operations.md` if diagnostics or retention behavior changes.
-- Remove the Scriptorium migration item from `docs/roadmap/future.md` once the
-  feature is implemented.
-- Replace `docs/roadmap/implementation.md` with a completed note or remove it
-  after implementation is complete, according to the repository's current
-  roadmap cleanup pattern.
-
-Acceptance tests and inspections:
-
-- `rg -n "llm_profiles|OpenAICompatibleClient|openai-compatible|RenderUserSystem|NOTARIUS_LLM_DEFAULT" internal docs examples`
-  should return only intentional historical/deferred references, if any.
-- `rg -n "scriptorium|session-id|profile_dir|profile_file" docs examples`
-  should show current-behavior docs and examples are updated.
-- `go test ./...`
-- `go vet ./...`
-- `go build ./cmd/notarius`
-
-## Cross-Stage Review Checklist
-
-Before considering the implementation complete, verify:
-
-- No Scriptorium public types appear in chunk, extract, or normalize contracts.
-- No raw source input, reference content, prompt text, schema JSON, API key, or
-  bearer token appears in manifests or default diagnostics.
-- The shared transcript message uses original Seriatim JSON bytes exactly.
-- Large reference content can be supplied as Scriptorium prompt inputs without
-  changing module-facing reference slot contracts.
-- `--session-id` is easy for an external orchestrator to pass.
-- Empty `llm_profile` lets prompt defaults work; explicit `llm_profile` and
-  `--llm-profile` select Scriptorium profile IDs.
-- Production Notarius LLM execution goes through Scriptorium.
-- Current-behavior documentation describes only implemented behavior.
