 # Audita
 
-Audita is a framework-first transcript correction application. The public `audita` package provides:
+Audita is a transcript polishing CLI.
 
-- deterministic transcript normalization
-- token-batched module orchestration
-- concrete `glossary`, `homophones`, `spoken_word`, and `grammar` modules built on reusable proposal / validator contracts
-- structured run reporting and work-dir diagnostics
+`audita process` validates transcript/glossary input, normalizes and chunks transcript segments, runs the default correction pipeline, and emits corrected transcript output plus machine-readable diagnostics and reports.
 
-The previous working implementation has been preserved as `audita_prototype` inside this repository. Its full regression suite lives under `tests/audita_prototype`.
+## What Audita Does
 
-## Development
+Default module sequence:
+- `glossary`
+- `homophones`
+- `glossary`
+- `spoken_word`
+- `grammar`
 
-This project is set up for `uv`.
+Pipeline behavior includes:
+- glossary-backed domain/acoustic corrections
+- conservative homophone and mistranscription corrections
+- conservative spoken-word dysfluency cleanup with semantic guardrails
+- grammar/punctuation/capitalization/formatting cleanup
+- validator-chain enforcement before application
+- malformed module-stage LLM payloads degrade to warnings/rejections instead of failing the run
+- run reports and diagnostics artifacts with secret redaction
+
+## Build and Install
+
+Build a local binary:
 
 ```sh
-uv sync --extra dev
-uv run pytest
+go build -o ./bin/audita ./cmd/audita
 ```
 
-## Usage
-
-Process a transcript with the current framework implementation:
+Install into your Go bin directory:
 
 ```sh
-uv run audita process transcript.json --glossary glossary.yaml --output corrected.json
+go install ./cmd/audita
 ```
 
-The framework currently runs this default module sequence:
-
-1. `glossary`
-2. `homophones`
-3. `glossary`
-4. `spoken_word`
-5. `grammar`
-
-Resolved run instance names are auto-numbered for repeats, so the default report pipeline is:
-
-1. `glossary_1`
-2. `homophones`
-3. `glossary_2`
-4. `spoken_word`
-5. `grammar`
-
-The default module sequence is fully implemented today:
-
-- `glossary` proposes glossary-supported acoustic corrections
-- `homophones` proposes conservative homophone and mistranscription corrections
-- `spoken_word` proposes conservative dysfluency cleanup
-- `grammar` proposes punctuation, capitalization, and spacing cleanup only
-
-To run a custom module sequence, pass `--modules`:
+CLI help:
 
 ```sh
-uv run audita process transcript.json --glossary glossary.yaml --modules grammar --output corrected.json
+audita --help
+audita process --help
+audita config --help
 ```
 
-To also write a structured JSON report:
+## Test
+
+Run all tests:
 
 ```sh
-uv run audita process transcript.json --glossary glossary.yaml --output corrected.json --report-json report.json
+go test ./...
 ```
 
-From a checked-out repository, you can also use the root launcher:
+## Basic Usage
+
+Required inputs:
+- transcript JSON path (positional argument)
+- `--glossary <glossary.yaml>`
+
+Recommended run:
 
 ```sh
-./audita process transcript.json --glossary glossary.yaml --output corrected.json
+audita process transcript.json \
+  --glossary glossary.yaml \
+  --output corrected.json \
+  --report-json report.json
 ```
 
-For a system-wide command, install the source tree under `/usr/local/src/audita`, sync dependencies there, and symlink the root launcher into your `PATH`:
+Select an explicit output schema (default is `bare-segments`):
 
 ```sh
-cd /usr/local/src/audita
-uv sync --extra dev
-ln -s /usr/local/src/audita/audita /usr/local/bin/audita
-audita process transcript.json --glossary glossary.yaml --output corrected.json
+audita process transcript.json \
+  --glossary glossary.yaml \
+  --output-schema audita-v1 \
+  --output corrected.json \
+  --report-json report.json
 ```
 
-Without `--output`, Audita writes the corrected transcript JSON to stdout and progress logs to stderr.
-`--report-json` writes a separate machine-readable run report and never mixes report data into stdout.
-
-Useful configuration can be supplied by CLI flag or environment variable. CLI flags take precedence over environment variables. Default OpenRouter runs require LLM API credentials, because the `glossary`, `homophones`, `spoken_word`, and `grammar` modules make real LLM calls. Self-hosted or other non-default OpenAI-compatible endpoints may not require credentials. `AUDITA_LLM_API_KEY` and `--llm-api-key` are the preferred provider-neutral credential surfaces, while `OPENROUTER_API_KEY` remains supported as a backward-compatible fallback.
-
-| Environment variable | CLI flag | Default | Purpose |
-| --- | --- | --- | --- |
-| `AUDITA_MODULES` | `--modules` | `glossary,homophones,glossary,spoken_word,grammar` | Comma-separated logical module keys to run; CLI overrides the environment value |
-| `AUDITA_LLM_API_KEY` | `--llm-api-key` | unset | Preferred provider-neutral LLM API credential; required for the default OpenRouter endpoint and optional for non-default endpoints; CLI overrides both environment-key variants |
-| `AUDITA_VALIDATION_LLM_API_KEY` | `--validation-llm-api-key` | unset | Validation-phase LLM API credential; defaults to the primary LLM API key and is optional for non-default validation endpoints |
-| `AUDITA_MODEL` | `--model` | `openrouter/google/gemma-4-31b-it` | LLM model name sent to the configured OpenAI-compatible endpoint |
-| `AUDITA_VALIDATION_MODEL` | `--validation-model` | unset | Validation-phase LLM model; defaults to `AUDITA_MODEL` |
-| `AUDITA_BASE_URL` | `--base-url` | `https://openrouter.ai/api/v1` | OpenAI-compatible API base URL |
-| `AUDITA_VALIDATION_BASE_URL` | `--validation-base-url` | unset | Validation-phase OpenAI-compatible API base URL; defaults to `AUDITA_BASE_URL` |
-| `AUDITA_LLM_TIMEOUT_SECONDS` | `--llm-timeout-seconds` | `600` | Per-request timeout in seconds for LLM calls to the configured OpenAI-compatible endpoint |
-| `AUDITA_VALIDATION_LLM_TIMEOUT_SECONDS` | `--validation-llm-timeout-seconds` | unset | Validation-phase per-request timeout in seconds; defaults to `AUDITA_LLM_TIMEOUT_SECONDS` |
-| `AUDITA_VALIDATION_MAX_PROMPT_TOKENS` | `--validation-max-prompt-tokens` | `2048` | Maximum estimated tokens per validation-phase LLM prompt batch |
-| `AUDITA_TARGET_SECTIONS` | `--target-sections` | unset | Exact number of contiguous proposal-stage transcript sections; errors if min/max token bounds cannot be satisfied |
-| `AUDITA_MAX_RETRIES` | `--max-retries` | `3` | Maximum Instructor retries for structured responses |
-| `AUDITA_VALIDATION_MAX_RETRIES` | `--validation-max-retries` | unset | Validation-phase structured-output retries; defaults to `AUDITA_MAX_RETRIES` |
-| `AUDITA_VALIDATION_LLM_CONCURRENCY` | `--validation-llm-concurrency` | unset | Validation-phase LLM concurrency; defaults to `AUDITA_LLM_CONCURRENCY` |
-| `AUDITA_MAX_SECTION_TOKENS` | `--max-section-tokens` | `8192` | Maximum estimated tokens per proposal-stage transcript section |
-| `AUDITA_MIN_SECTION_TOKENS` | `--min-section-tokens` | `2048` | Minimum estimated tokens per proposal-stage transcript section when balancing for concurrency |
-| `AUDITA_GLOSSARY_CONFIDENCE_THRESHOLD` | `--glossary-confidence-threshold` | `0.8` | Minimum confidence required for glossary proposals to survive validation |
-| `AUDITA_GRAMMAR_CONFIDENCE_THRESHOLD` | `--grammar-confidence-threshold` | `0.8` | Minimum confidence required for grammar proposals to survive validation |
-| `AUDITA_HOMOPHONES_CONFIDENCE_THRESHOLD` | `--homophones-confidence-threshold` | `0.8` | Minimum confidence required for homophone proposals to survive validation |
-| `AUDITA_SPOKEN_WORD_CONFIDENCE_THRESHOLD` | `--spoken-word-confidence-threshold` | `0.8` | Minimum confidence required for spoken-word proposals to survive validation |
-| `AUDITA_NORMALIZE_MAX_SEGMENT_GAP` | `--normalize-max-segment-gap` | `4.0` | Same-speaker gaps eligible for deterministic merging |
-| `AUDITA_NORMALIZE_ELLIPSIS_GAP` | `--normalize-ellipsis-gap` | `3.5` | Same-speaker gaps above this value are joined with ` ... ` |
-| `AUDITA_NORMALIZE_MAX_SEGMENT_DURATION` | `--normalize-max-segment-duration` | `60.0` | Maximum merged segment duration |
-| `AUDITA_NORMALIZE_MAX_SEGMENT_TOKENS` | `--normalize-max-segment-tokens` | `2048` | Maximum merged segment prompt payload size |
-| `AUDITA_WORK_DIR` | `--work-dir` | `/tmp/audita` | Per-run scratch diagnostics directory |
-| `AUDITA_WORK_DIR_RETENTION` | `--work-dir-retention` | `auto` | Whether to retain the per-run work directory: `auto`, `always`, or `never` |
-
-Set `AUDITA_MODULES=grammar` to run only the grammar module by default, or override it per command with `--modules`.
-
-Validation-phase LLM settings inherit from the primary `AUDITA_*` LLM settings by default. Set any of the `AUDITA_VALIDATION_*` values only when you want LLM-backed validators to use a different model, endpoint, credential, timeout, retry budget, or concurrency level.
-
-OpenRouter remains the default out of the box:
+Recommended config-based run:
 
 ```sh
-export AUDITA_LLM_API_KEY=your-openrouter-key
-audita process transcript.json --glossary glossary.yaml --output corrected.json
+audita process transcript.json \
+  --glossary glossary.yaml \
+  --config audita.yml \
+  --output corrected.json \
+  --report-json report.json
 ```
 
-You can point Audita at any OpenAI-compatible endpoint by changing `AUDITA_BASE_URL` and, if needed, `AUDITA_MODEL`. For example, a local vLLM server:
+Explicit module override:
 
 ```sh
-export AUDITA_BASE_URL=http://localhost:8000/v1
-export AUDITA_MODEL=meta-llama/Llama-3.1-8B-Instruct
-audita process transcript.json --glossary glossary.yaml --output corrected.json
+audita process transcript.json \
+  --glossary glossary.yaml \
+  --modules glossary,homophones,grammar \
+  --output corrected.json \
+  --report-json report.json
 ```
 
-If your self-hosted endpoint requires authentication, you can still set `AUDITA_LLM_API_KEY`; Audita simply no longer requires it for non-default endpoints.
-
-Or the actual OpenAI API:
+Optional transcript background context:
 
 ```sh
-export AUDITA_LLM_API_KEY=your-openai-key
-export AUDITA_BASE_URL=https://api.openai.com/v1
-export AUDITA_MODEL=gpt-4.1-mini
-audita process transcript.json --glossary glossary.yaml --output corrected.json
+audita process transcript.json \
+  --glossary glossary.yaml \
+  --transcript-description "Brief context that may help resolve ambiguous terms." \
+  --output corrected.json
 ```
 
-`AUDITA_WORK_DIR` stores per-run diagnostics while processing. Under the default `AUDITA_WORK_DIR_RETENTION=auto`, clean successful runs are removed, while failed runs and successful runs with final skipped corrections are preserved. Use `always` to keep every run directory and `never` to remove successful run directories even when skips remain.
-Failed runs always preserve the run directory and include an authoritative `report.json` alongside normalization and prompt/response diagnostics.
+The transcript description is background context only and does not override transcript content.
 
-## Prototype Archive
+Write transcript JSON to stdout (no `--output`):
 
-The archived prototype remains importable as `audita_prototype` and is still covered by its original regression suite. This is intentional: the new `audita` package is a framework-oriented rewrite, not a thin wrapper around the old code.
+```sh
+audita process transcript.json --glossary glossary.yaml
+```
+
+Control diagnostics location/retention:
+
+```sh
+audita process transcript.json \
+  --glossary glossary.yaml \
+  --work-dir /tmp/audita \
+  --work-dir-retention auto \
+  --output corrected.json \
+  --report-json report.json
+```
+
+## Stdout/Stderr Contract
+
+- With `--output`, stdout is expected to be empty on success.
+- Without `--output`, stdout contains transcript JSON only on success.
+- `--report-json` writes a file and is never printed to stdout.
+- stderr is human-readable diagnostics/errors.
+- successful runs remain quiet on stderr even when module warnings are recorded in report/diagnostics artifacts.
+
+For subprocess orchestration guidance, see [`docs/subprocess-operations.md`](docs/subprocess-operations.md).
+
+## Configuration
+
+Precedence:
+1. defaults
+2. config file (`--config`, `AUDITA_CONFIG`, or default search paths when present: `/usr/local/etc/audita/config.yml`, then `/etc/audita/config.yml`)
+3. environment (`AUDITA_*`)
+4. CLI flags
+
+Config commands:
+
+```sh
+audita config validate --config audita.yml
+audita config print-effective --config audita.yml
+```
+
+For full config-file schema and examples, see [`docs/configuration.md`](docs/configuration.md).

+# Audita Architecture
+
+## Scope
+This document describes the production architecture implemented in this repository today.
+
+Audita is a single-process Go CLI that:
+- loads effective runtime configuration;
+- reads transcript and glossary inputs;
+- normalizes and sections transcripts;
+- runs a built-in module pipeline with validator chains;
+- writes transcript output and run diagnostics.
+
+## Runtime entrypoints
+Primary CLI commands:
+- `audita process <transcript.json> --glossary <glossary.yaml> [flags]`
+- `audita config validate --config <config.yml>`
+- `audita config print-effective [--config <config.yml>]`
+
+Command ownership lives in `internal/cli/run.go`.
+
+## Configuration model
+`internal/core/config` owns defaults, file parsing, environment overrides, CLI overrides, and validation.
+
+Effective-config loading for `process` and `config print-effective` is centralized in:
+- `ResolveConfigPath`
+- `LoadEffectiveConfig`
+
+Effective precedence for `audita process`:
+1. defaults
+2. config file
+3. environment overrides
+4. CLI overrides
+
+`audita config validate` is intentionally file-only validation:
+- load versioned file;
+- apply onto defaults;
+- validate;
+- do not apply environment overrides.
+
+Supported module and output-schema keys are validated through shared catalogs:
+- module keys: `internal/core/modulecatalog`
+- output schemas: `internal/core/outputschema`
+
+## Pipeline and module orchestration
+The built-in module sequence is configured in runtime config and executed by `internal/framework/runner` through resolved module specs.
+
+Current default sequence:
+- `glossary`
+- `homophones`
+- `glossary`
+- `spoken_word`
+- `grammar`
+
+Execution behavior:
+- modules execute serially over the working transcript;
+- section proposal work can run concurrently within a module;
+- validator execution happens on generated proposals before application;
+- approved proposals are applied once per module in deterministic proposal-index order.
+
+Production modules remain separate packages:
+- `internal/modules/glossary`
+- `internal/modules/homophones`
+- `internal/modules/spoken_word`
+- `internal/modules/grammar`
+
+## Proposal generation and prompt context
+Shared proposal plumbing is centralized in `internal/framework/proposal_generation`.
+
+Module packages provide:
+- module identity and replacement policy;
+- module-specific prompt message building;
+- built-in validator chain selection.
+
+Shared prompt payload helpers are in `internal/framework/promptcontext`.
+
+## Validator architecture
+Built-in validator construction and chain composition live in `internal/validators`.
+
+Shared validator runtime mechanics live in `internal/framework/validators`.
+
+Execution class metadata (deterministic vs LLM-backed) is centralized in `internal/validators/metadata` and used for ordering and reporting classification.
+
+## Structured LLM boundary
+All production LLM calls go through the internal contract:
+- `contracts.StructuredLLMClient`
+- `CompleteStructured(ctx, req, out)`
+
+The OpenAI-compatible HTTP adapter is implemented in `internal/framework/llm`.
+
+Structured response schemas are registered in `internal/framework/responseschema` and attached to requests via `response_format` metadata.
+
+Malformed structured-output detection is centralized in `internal/framework/structuredoutput` and reused by proposal generation and validator execution so downgrade behavior stays consistent.
+
+## Stage naming and diagnostics metadata
+Diagnostics stage naming is centralized in `internal/framework/stagename`:
+- module proposal stage names;
+- proposal-generation stage names;
+- validator batch stage names.
+
+Prompt metadata and response-schema metadata each expose canonical diagnostics maps via:
+- `prompts.Metadata.DiagnosticsMap()`
+- `responseschema.Schema.DiagnosticsMap()`
+
+## Diagnostics and reporting
+Run-directory artifacts are owned by `internal/core/diagnostics`.
+
+Stable artifact names are centralized constants (for example transcript artifacts, `invocation.json`, `effective-config.json`, `utilization-diagnostics.json`, `correction-ledger.json`, `report.json`, `error.log`).
+
+Report diagnostics path metadata is constructed through `BuildDiagnosticsMetadata`, which keeps run-directory artifact references consistent between success and failure reports.
+
+## Secret redaction
+Redaction responsibilities are split by concern:
+- structural config redaction: `config.Config.Redacted()`
+- byte/string payload redaction for diagnostics and surfaced errors: framework redaction utilities.
+
+Configured LLM secret extraction is centralized in `llm.ConfiguredSecrets(cfg)` and reused across proposal and validator diagnostics paths.
+
+## Output contracts
+Transcript output schema selection is owned by `internal/core/outputschema`.
+
+Supported schemas:
+- `bare-segments`
+- `audita-v1`
+
+Unknown schema keys fail validation and runtime resolution.
+
+## Key package map
+Core packages:
+- `internal/core/config`
+- `internal/core/schema`
+- `internal/core/normalization`
+- `internal/core/chunking`
+- `internal/core/diagnostics`
+- `internal/core/reporting`
+- `internal/core/modulecatalog`
+- `internal/core/outputschema`
+
+Framework packages:
+- `internal/framework/contracts`
+- `internal/framework/proposals`
+- `internal/framework/proposal_generation`
+- `internal/framework/promptcontext`
+- `internal/framework/runner`
+- `internal/framework/validators`
+- `internal/framework/llm`
+- `internal/framework/responseschema`
+- `internal/framework/stagename`
+- `internal/framework/structuredoutput`

+Domain packages:
+- `internal/modules/*`

+# Audita Diagnostics
+
+This document describes the run-directory diagnostics artifacts produced by `audita process`.
+
+## Purpose
+
+Diagnostics provide machine-readable run context and execution artifacts for:
+- failure debugging;
+- validator/correction review;
+- post-run performance analysis.
+
+Diagnostics are written under the configured work directory (`--work-dir`) when run-directory initialization succeeds.
+
+## Core artifacts
+
+Typical artifacts in each run directory:
+- `source-transcript.json`
+- `source-transcript-parsed.json`
+- `normalized-transcript.json`
+- `normalization-summary.json`
+- `chunking-summary.json`
+- `invocation.json`
+- `effective-config.json` (redacted)
+- module/validator LLM interaction artifacts
+- `report.json`
+- `error.log` on failure
+
+## Utilization diagnostics artifact
+
+Artifact:
+- `utilization-diagnostics.json`
+
+High-level fields:
+- `effective_concurrency`:
+  - total/proposal/validation LLM concurrency limits in effect.
+- `run_timing`:
+  - run wall time;
+  - scheduler queue wait time;
+  - LLM execution time;
+  - deterministic validator time;
+  - max/average in-flight LLM calls.
+- `llm_calls`:
+  - total proposal and validation LLM call counts.
+- `modules`:
+  - module-level timing summaries.
+- `validators`:
+  - per-validator timing summaries keyed by stable validator key.
+
+## Correction ledger artifact
+
+Artifact:
+- `correction-ledger.json`
+
+Ledger records are flattened review entries derived from module results and include:
+- module/proposal identity (`module_key`, `module_instance`, `proposal_index`, `segment_id`);
+- correction text fields and replacement policy when available;
+- disposition:
+  - `applied`
+  - `rejected`
+  - `skipped`
+  - `failed`
+- stable reason codes/messages;
+- deterministic and LLM validator decision snapshots using stable validator keys.
+
+Validator rejection and proposal-application skip are distinct dispositions.
+Module warnings are reported in module results and diagnostics metadata, but do not create standalone correction-ledger rows.
+
+## Report references
+
+`report.json` and optional `--report-json` output include diagnostics metadata paths for:
+- utilization diagnostics artifact;
+- correction ledger artifact;
+- existing transcript/normalization/chunking/invocation/effective-config artifacts.
+
+Module report entries also include warning records for malformed proposal-generation payloads and malformed validator batches.
+
+## Retention behavior
+
+Run-directory retention follows configured policy:
+- `always`: keep all run directories;
+- `never`: keep successful run directories;
+- `auto`: keep failed runs and successful runs with skipped/rejected corrections.
+
+## Redaction guarantees
+
+API keys and other configured secrets are redacted from:
+- `effective-config.json`;
+- LLM interaction diagnostics artifacts;
+- reports and surfaced errors.
+
+## Debugging guide
+
+When debugging:
+- slow runs:
+  - inspect `utilization-diagnostics.json` (`run_timing`, `modules`, `validators`, in-flight metrics).
+- validator rejections:
+  - inspect `correction-ledger.json` rejected entries and matching validator decisions;
+  - inspect validator response diagnostics payloads.
+- module warnings:
+  - inspect module `warnings` entries in `report.json` or `--report-json`;
+  - follow any diagnostic artifact path on the warning to the recorded error/response payload.
+- application skips:
+  - inspect `correction-ledger.json` skipped entries and skip reason codes;
+  - compare with validator decisions to distinguish validation rejection vs apply-time skip.

+# Audita Output Schemas
+
+This document describes the built-in transcript output schema registry used by `audita process`.
+
+## Supported schema names
+
+### `bare-segments`
+
+Status:
+- implemented
+- default output schema
+
+Shape:
+- top-level JSON array of transcript segments
+
+Segment fields:
+- `id`
+- `speaker`
+- `start`
+- `end`
+- `text`
+- optional `categories`
+
+Compatibility:
+- this preserves the long-standing output shape used by existing consumers.
+
+### `audita-v1`
+
+Status:
+- implemented
+
+Shape:
+- top-level JSON object:
+  - `schema`: `"audita-v1"`
+  - `version`: `"v1"`
+  - `segments`: transcript segment array
+
+Segment fields inside `segments` match `bare-segments` segment fields.
+
+Compatibility:
+- this is the Audita-native object format with explicit schema/version metadata.
+
+### `seriatim-intermediate`
+
+Status:
+- deferred / not implemented
+
+Current behavior:
+- selecting `seriatim-intermediate` fails clearly as an unsupported output schema.
+
+Reason:
+- a concrete, repository-backed contract for this schema has not been finalized yet.
+
+## Selection
+
+Choose output schema with CLI:
+
+```sh
+audita process <transcript.json> --glossary <glossary.yaml> --output-schema audita-v1
+```
+
+Or in file config:
+
+```yaml
+version: 1
+output:
+  schema: audita-v1
+```
+
+Precedence remains:
+1. defaults
+2. file config
+3. environment overrides
+4. CLI overrides
+
+`--output-schema` overrides `output.schema` when both are supplied.
+
+## Output routing behavior
+
+- With `--output`, transcript JSON is written to file using the selected schema and stdout stays empty on success.
+- Without `--output`, stdout contains transcript JSON only, using the selected schema.
+- `--report-json` writes report JSON to file and does not write report payloads to stdout.
+
+## Backward-compatibility expectations
+
+- default schema stays `bare-segments` for compatibility unless explicitly changed in a future breaking release;
+- supported schema names are treated as stable public contract values;
+- unsupported schema names fail before output write.

+# Audita Prompts
+
+This document describes Audita's built-in embedded prompt assets and prompt registry behavior.
+
+## Why embedded prompt assets
+
+Audita embeds production prompt text into the binary so runtime behavior is:
+- deterministic;
+- auditable;
+- dependency-light;
+- not dependent on external prompt files at execution time.
+
+Prompt text is authored as Markdown assets and rendered by Go code using typed template data.
+
+## Built-in prompt registry
+
+The prompt registry lives in `internal/prompts` and is responsible for:
+- loading embedded prompt assets;
+- registering stable prompt IDs and versions;
+- recording prompt source metadata;
+- computing deterministic SHA-256 source hashes;
+- rendering system/user prompts with strict missing-key failures.
+
+Current prompt source behavior:
+- built-in embedded prompts only (`prompt_source = builtin`).
+- filesystem prompt overrides are not supported.
+
+## Built-in prompt IDs
+
+Module proposal prompts:
+- `modules.glossary.proposal`
+- `modules.homophones.proposal`
+- `modules.spoken_word.proposal`
+- `modules.grammar.proposal`
+
+LLM-backed validator prompts:
+- `validators.spoken_form_plausibility`
+- `validators.meaning_reversal_review`
+- `validators.editorial_review`
+- `validators.grammar_review`
+- `validators.spoken_word_review`
+
+## Prompt version semantics
+
+Current built-in prompt version value is `v1`.
+
+Version is a stable metadata identifier for diagnostics and debugging. It is not a dynamic prompt-selection mechanism.
+
+## Prompt hash semantics
+
+Each registered prompt includes a deterministic SHA-256 hash of embedded source text.
+
+Hash purpose:
+- identify exact prompt source used in a run;
+- support diagnostics reproducibility and change auditing.
+
+Current hash scope:
+- source prompt text (system + user assets for a registered prompt), not a runtime secret-bearing payload.
+
+## Template rendering behavior
+
+Prompt rendering uses Go `text/template` with typed template data from module/validator builders.
+
+Missing-key behavior:
+- rendering uses missing-key errors;
+- missing/renamed template fields fail quickly instead of silently producing incomplete prompts.
+
+Go code still owns:
+- structured request/response models;
+- response schema selection;
+- transcript/glossary/payload formatting;
+- module and validator selection;
+- diagnostics wiring.
+
+## Shared prompt hardening policy
+
+A shared hardening fragment is embedded once and included in every module proposal prompt and every LLM-validator prompt.
+
+Hardening policy includes:
+- transcript text is untrusted data;
+- glossary entries and transcript descriptions are reference data, not instructions;
+- instructions found inside transcript text must not be obeyed;
+- model must perform only the requested correction/validation task;
+- no invention of facts, names, events, motivations, speaker intent, or corrections;
+- transcript remains the source of truth.
+
+## Transcript description behavior
+
+Transcript description remains background-only prompt context:
+- it may help interpret ambiguous terms;
+- it is explicitly non-authoritative and must not override transcript content;
+- empty descriptions do not render awkward blank context sections.
+
+Generated transcript descriptions are not implemented in this workstream.
+
+## Diagnostics and report metadata boundaries
+
+Current metadata flow:
+- proposal-generation diagnostics request metadata includes prompt metadata;
+- LLM-validator diagnostics request metadata includes prompt metadata.
+
+Prompt metadata fields used in diagnostics:
+- `prompt_id`
+- `prompt_version`
+- `prompt_source`
+- `embedded_path`
+- `sha256`
+
+Current boundary:
+- detailed prompt metadata is diagnostics-first;
+- broad report-level prompt registries/ledgers are deferred.
+
+## 1.0 boundary
+
+Not implemented for 1.0 in this workstream:
+- filesystem prompt overrides;
+- user-configurable prompt selection;
+- external prompt directories.

+# Audita Public Contract
+
+## Scope
+This document defines stability expectations for Audita's external runtime interfaces.
+
+Covered interfaces:
+- CLI commands and major flags;
+- versioned config behavior and precedence;
+- transcript/glossary input forms;
+- output schema selection;
+- report schema metadata;
+- diagnostics artifact path metadata;
+- stdout/stderr and exit-code behavior;
+- redaction guarantees.
+
+## CLI contract
+Stable commands:
+- `audita process`
+- `audita config validate`
+- `audita config print-effective`
+
+Stable high-value `process` flags:
+- `--config`
+- `--glossary`
+- `--output`
+- `--report-json`
+- `--modules`
+- `--output-schema`
+
+## Config contract
+Supported config format:
+- YAML;
+- `version: 1`;
+- strict unknown-field rejection.
+
+Path resolution for `process` and `config print-effective`:
+1. `--config`
+2. `AUDITA_CONFIG`
+3. `/usr/local/etc/audita/config.yml`
+4. `/etc/audita/config.yml`
+
+Missing explicit path is an error. Missing default paths is non-fatal.
+
+Precedence for `process`:
+1. defaults
+2. file config
+3. environment overrides
+4. CLI overrides
+
+`config validate` remains file-only validation (defaults + file config; no env overrides).
+
+Module and output-schema keys are validated against built-in catalogs. Unknown keys fail validation.
+
+## Input contract
+Supported transcript JSON top-level forms:
+- array of segments
+- object with `segments` array
+
+Supported glossary YAML form:
+- top-level `glossary` list with required entry fields validated by schema parsing.
+
+## Output schema contract
+Supported transcript output schemas:
+- `bare-segments` (default)
+- `audita-v1`
+
+Unknown schema keys fail before output write.
+
+## Report metadata contract
+Process reports include stable report metadata fields:
+- `report_schema_name`
+- `report_schema_version`
+- `output_schema`
+- `config_version` (when file config is loaded)
+
+Current values:
+- `report_schema_name = audita-process-report`
+- `report_schema_version = v1`
+
+`--report-json` output and run-directory `report.json` use the same report schema metadata.
+
+Validator decision/rejection records use stable validator keys via `validator_name`.
+
+## Diagnostics metadata contract
+When run-directory initialization succeeds, diagnostics metadata paths reference stable artifacts, including:
+- transcript and normalization artifacts;
+- chunking summary;
+- invocation metadata;
+- redacted effective config;
+- utilization diagnostics;
+- correction ledger;
+- `error.log` on failures.
+
+LLM interaction diagnostics include stable prompt and structured-schema identifiers where applicable.
+
+## Stdout/stderr and exit codes
+Success:
+- with `--output`, stdout is empty;
+- without `--output`, stdout contains transcript JSON only;
+- report JSON is not written to stdout.
+
+Failures:
+- nonzero exit;
+- human-readable stderr summary;
+- diagnostics directory path on stderr when available.
+
+Exit codes:
+- `0` success
+- nonzero failure
+
+## Redaction contract
+Configured secrets are redacted from:
+- effective config outputs;
+- diagnostics artifacts;
+- report artifacts;
+- surfaced adapter/runtime errors.
+
+## Compatibility policy
+Stable command behavior, schema names, report metadata keys, diagnostics-path field semantics, and validator key identities are treated as public contract.
+
+Additive fields are acceptable when existing fields and behavior remain compatible.

+# Structured LLM Architecture
+
+## Scope
+This document describes Audita's structured LLM runtime boundary and adapter behavior.
+
+## Runtime boundary
+Production LLM integration depends on the internal contract only:
+- `contracts.StructuredLLMClient`
+- `CompleteStructured(ctx, req, out)`
+
+Provider SDK types do not leak past this boundary.
+
+## Adapter ownership
+`internal/framework/llm` owns the OpenAI-compatible HTTP adapter and shared LLM runtime utilities.
+
+Key responsibilities:
+- request assembly;
+- timeout/cancellation propagation;
+- bounded retry behavior;
+- scheduler integration;
+- provider response decoding;
+- error redaction.
+
+## Structured schema registry
+Structured response schemas are registered in `internal/framework/responseschema` and include stable metadata:
+- `id`
+- `version`
+- `name`
+- `json_schema`
+- `sha256`
+
+Current schema keys:
+- `correction_set`
+- `validator_decision_set`
+
+Schema metadata is attached to diagnostics through `Schema.DiagnosticsMap()`.
+
+## Request shape assumptions
+Audita targets OpenAI-compatible chat-completions endpoints and sends structured requests with:
+- model;
+- chat messages;
+- `response_format.type = json_schema`;
+- schema name and JSON schema payload.
+
+## Local validation remains mandatory
+Provider schema enforcement is treated as transport-level guardrails.
+
+Audita still validates output locally before applying behavior changes:
+- proposal decoding and proposal invariants;
+- validator decision decoding and cardinality checks;
+- deterministic validation and apply-time rules.
+
+## Shared malformed-output policy
+Malformed structured-output classification is centralized in `internal/framework/structuredoutput`.
+
+Proposal generation and validator execution both use this shared classifier so downgrade behavior cannot drift between the two paths.
+
+## Secrets and redaction
+Secret extraction for LLM redaction is centralized in `llm.ConfiguredSecrets(cfg)` and reused by proposal and validator diagnostics writers.
+
+Secrets are redacted from:
+- diagnostics artifacts;
+- report artifacts;
+- surfaced adapter/runtime errors.
+
+## Concurrency and scheduling
+LLM execution is constrained by composed scheduler limits:
+- total LLM concurrency;
+- proposal LLM concurrency;
+- validation LLM concurrency.
+
+The scheduler is FIFO and context-aware so permits are released on success, failure, and cancellation.

+# Audita Validators
+
+## Scope
+This document defines the built-in validator system used by production module runs.
+
+## Ownership boundaries
+Built-in validator keys, constructors, and module chains are owned by `internal/validators`.
+
+Shared runtime execution mechanics are owned by `internal/framework/validators`, including:
+- validator request/result models;
+- deterministic proposal checks;
+- LLM validator batching and execution;
+- decision-cardinality enforcement;
+- diagnostics integration.
+
+Execution class metadata is owned by `internal/validators/metadata`.
+
+## Stable validator keys
+Deterministic:
+- `proposal_shape`
+- `confidence_threshold`
+- `original_text_presence`
+- `non_empty_corrected_text`
+- `no_effect`
+- `protected_terms`
+
+LLM-backed:
+- `spoken_form_plausibility`
+- `meaning_reversal_review`

+- `no_effect`
+- `original_text_presence`
+- `confidence_threshold`
+- `protected_terms`
+- `non_empty_corrected_text`
+- `editorial_review`
+- `meaning_reversal_review`
+
+## Ordering and execution semantics
+Validator ordering is based on canonical metadata:
+- deterministic validators run before LLM-backed validators.
+
+Within each module stage:
+- proposals are generated per section;
+- validator chains execute on those proposals;
+- approved proposals are applied once after section work settles.
+
+## Malformed payload behavior
+Malformed structured-output from proposal generation and LLM validator calls is downgraded, not treated as a process-fatal transport error.
+
+Current outcomes:
+- malformed proposal-generation payloads produce section/module warnings and zero proposals for the affected section;
+- malformed validator decision payloads reject the affected validator batch with warnings;
+- deterministic validator behavior and runner order remain unchanged.
+
+## Reporting identity
+Reports and diagnostics use stable validator keys as identifiers.
+
+Correction-ledger deterministic-vs-LLM classification is derived from canonical validator metadata, not package-local hardcoded maps.
+
+## Prompt assets
+LLM validator prompt assets and prompt metadata are documented in [Prompts](./prompts.md).

+2. `AUDITA_CONFIG`
+3. `/usr/local/etc/audita/config.yml` (if present)
+4. `/etc/audita/config.yml` (if present)
+
+Missing-path behavior:
+- missing `--config` path is an error;
+- missing `AUDITA_CONFIG` path is an error;
+- missing both default paths is non-fatal.
+
+## Effective precedence
+`audita process` effective precedence:
+1. defaults
+2. file config
+3. environment overrides
+4. CLI overrides
+
+`audita config print-effective` uses:
+1. defaults
+2. file config
+3. environment overrides
+
+`audita config validate` intentionally uses file-only validation:
+1. defaults
+2. file config
+
+Environment overrides are not applied in `config validate`.

+
+## Module and output-schema validation
+`pipeline.modules` keys are validated against the built-in supported module catalog.
+
+Supported module keys:
+- `glossary`
+- `homophones`
+- `spoken_word`
+- `grammar`
+
+Repeated supported module keys are allowed.
+
+`output.schema` is validated against the built-in output schema catalog.
+
+Supported output schema keys:
+- `bare-segments`
+- `audita-v1`
+
+Unknown module keys and unknown output schema keys fail validation.
+
+## Duration field parsing
+Duration-like fields support:
+- numeric seconds (for example `120`, `3.5`)
+- duration strings (for example `120s`, `2m`)
+
+LLM timeout duration strings must resolve to whole seconds.
+
+## Secret handling
+Use `api_key_env` fields for secrets:
+- `llm.proposal.api_key_env`
+- `llm.validation.api_key_env`
+
+These fields store environment variable names, not secret values.
+
+Resolved secret values are redacted from:
+- `audita config print-effective` output;
+- diagnostics `effective-config.json`;
+- report and diagnostics payloads.
+
+## Commands
+Validate a file config:
+```sh
+audita config validate --config ./audita.yml
+```
+
+Print redacted effective config:
+```sh
+audita config print-effective --config ./audita.yml
+```
+
+## Compatibility notes
+Legacy compatibility flags and environment aliases remain available where implemented, but the stable configuration surface is the versioned YAML model described above.

+# Audita Development Workflow
+
+## Scope
+This document defines the canonical contributor workflow and engineering conventions for this repository.
+
+## Workflow
+1. Start from a clean understanding of scope and constraints.
+2. Make focused changes that preserve existing public behavior unless behavior change is explicitly intended.
+3. Run targeted tests for touched packages.
+4. Run `go test ./...` before finalizing substantial changes.
+5. Update affected documentation so it describes current behavior only.
+
+## Engineering conventions
+- Keep module packages separate: `glossary`, `homophones`, `spoken_word`, `grammar`.
+- Prefer narrow shared helpers and catalogs over broad abstractions.
+- Preserve diagnostics artifact naming and report field contracts unless intentionally changed.
+- Preserve CLI/config precedence semantics unless intentionally changed.
+- Treat stable validator keys, prompt identifiers, and output-schema keys as contract surfaces.
+
+## Configuration and runtime expectations
+- `audita process` precedence is defaults -> file -> env -> CLI.
+- `audita config validate` validates file config merged onto defaults only.
+- `audita config print-effective` includes environment overrides and prints redacted JSON.
+
+## Testing expectations
+- Add tests for new behavior and for bug fixes.
+- Keep deterministic fixtures stable.
+- Do not reduce existing parity, release-fixture, subprocess, or module-specific coverage without equivalent replacement.
+
+## Commit discipline
+- Keep commits scoped and reviewable.
+- Avoid mixing unrelated refactors with behavior changes.
+- Use clear plain-English commit messages.

+# Audita Subprocess Operations
+
+This document describes how parent processes should invoke `audita process` safely in production orchestration.
+
+## Recommended command form
+
+Use explicit file outputs for orchestrated runs:
+
+```sh
+audita process <transcript.json> \
+  --transcript-description "Brief context that may help resolve ambiguous terms." \
+  --glossary <glossary.yaml> \
+  --output <output-transcript.json> \
+  --report-json <report.json>
+```
+
+Additional flags that may be situationally appropriate:
+- `--config <path>` to select an explicit versioned config file.
+- `--output-schema <bare-segments|audita-v1>` to select transcript output shape.
+- `--work-dir <dir>` to control diagnostics location.
+- `--work-dir-retention <always|auto|never>` to control retained run directories.
+- `--total-llm-concurrency`, `--proposal-llm-concurrency`, and `--validation-llm-concurrency` when orchestration needs to set explicit LLM throughput controls.
+- `--modules ...` only when intentionally overriding the default sequence.
+
+For config-driven orchestration, validate config files in CI/preflight:
+
+```sh
+audita config validate --config <path>
+```
+
+## Stdout behavior
+
+- With `--output`: stdout is expected to be empty on success.
+- Without `--output`: stdout contains transcript JSON only on success.
+- Report JSON is never written to stdout.
+
+## Stderr behavior
+
+- Success path should be quiet or minimal human-readable logs.
+- Failure path writes concise human-readable errors.
+- When a diagnostics run directory exists, failure stderr includes its path.
+- Prompt/response diagnostic payloads are not streamed to stderr.
+
+## Output file behavior
+
+- `--output` writes transcript JSON in the selected output schema to the provided path.
+- Output write failures return nonzero and surface actionable errors.
+- The command does not silently ignore output write errors.
+
+## Report JSON behavior
+
+- `--report-json` writes a machine-readable process report to the requested path.
+- Run-directory `report.json` is written independently under diagnostics.
+- Best-effort failure reports are emitted when possible without masking the primary failure.
+- Report write failures return nonzero with clear stderr messaging.
+- Report diagnostics metadata references run-directory artifacts including utilization diagnostics and correction ledger paths when available.
+
+## Diagnostics directory behavior
+
+- Each run creates (when possible) a per-run diagnostics directory.
+- Typical artifacts include transcript, normalization, chunking, invocation, effective config, LLM diagnostics, `utilization-diagnostics.json`, `correction-ledger.json`, `report.json`, and `error.log` on failure.
+- Failed runs retain diagnostics.
+- Under `auto` retention, successful runs with skipped/rejected corrections are retained; clean successful runs may be removed.
+
+## Exit codes
+
+- `0`: success.
+- Nonzero: failure (input/schema/config/module/LLM/runtime/output/report/diagnostics errors).
+
+Treat any nonzero as a failed subprocess invocation.
+
+## Timeout and cancellation
+
+- Runtime operations propagate context cancellation and request timeouts through LLM/scheduler paths.
+- On cancellation or timeout, the process exits nonzero and should not hang.
+- If diagnostics were initialized before failure, failure artifacts remain available for debugging.
+
+## Secret redaction expectations
+
+API keys and configured secret values are redacted from:
+- reports (`--report-json` and run-dir `report.json`);
+- diagnostics artifacts (including effective config and LLM interaction artifacts);
+- surfaced adapter/runtime errors;
+- test fixtures and regression outputs.
+
+Parent-process logs should still avoid printing raw environment variables.
+
+## Parent-process pipe guidance
+
+To avoid deadlocks in orchestrators:
+- always read both stdout and stderr concurrently when invoking as a subprocess;
+- prefer file outputs (`--output`, `--report-json`) for machine workflows;
+- treat stderr as human-readable diagnostics, not structured data;
+- parse structured results from output/report files.
+
+For Go callers, prefer `exec.CommandContext` with explicit timeout/cancellation and buffered/streamed readers for both pipes.

+# Architecture Policy
+
+## Purpose
+
+This document defines Audita's development architecture and invariants for maintainers and LLM coding agents. It describes how the project is intended to be changed safely, based on behavior implemented in this repository today.
+
+User-facing behavior belongs in the README and focused runtime docs. Future or proposed work belongs only under `docs/roadmap/`.
+
+## Project Shape
+
+Audita is a single-process Go CLI for transcript polishing. The executable entrypoint is `cmd/audita`; command handling lives in `internal/cli`.
+
+The implemented `audita process` flow is:
+
+1. load effective config;
+2. read and validate transcript JSON and glossary YAML;
+3. normalize transcript segments;
+4. chunk the working transcript into sections;
+5. resolve configured module instances;
+6. run correction modules and validator chains;
+7. apply approved proposals deterministically;
+8. write transcript output, reports, and diagnostics artifacts.
+
+The current built-in modules are `glossary`, `homophones`, `spoken_word`, and `grammar`. The default configured module sequence repeats `glossary`.
+
+For external behavior and compatibility details, prefer links to existing behavior docs:
+
+- [Architecture overview](../architecture/architecture.md)
+- [Public contract](../architecture/public-contract.md)
+- [Diagnostics](../architecture/diagnostics.md)
+- [Structured LLM](../architecture/structured-llm.md)
+- [Validators](../architecture/validators.md)
+- [Prompts](../architecture/prompts.md)
+- [Output schemas](../architecture/output-schemas.md)
+- [Configuration](../configuration.md)
+
+## Core Design Principles
+
+- **Hexagonal architecture:** keep domain behavior behind narrow internal contracts. CLI, filesystem, config loading, diagnostics writing, and LLM transport are adapters around the core processing flow.
+- **Composable modules and validators:** correction stages and validators should remain small, explicit, and independently testable.
+- **Deterministic orchestration around LLM calls:** LLM responses are nondeterministic inputs. Proposal indexing, validator ordering, proposal application, reports, and output serialization must remain deterministic.
+- **Bounded and observable concurrency:** use the implemented schedulers and configured concurrency limits for LLM call sites. Preserve utilization diagnostics when changing scheduling or orchestration.
+- **Conservative correction behavior:** validate proposed corrections before application; apply accepted proposals through deterministic apply-time safety checks.
+- **Standard-library-first:** prefer the Go standard library. Narrow third-party dependencies are acceptable when they materially improve maintainability, such as `gopkg.in/yaml.v3` for YAML parsing.
+- **Current-behavior documentation:** non-roadmap docs must describe implemented behavior only.
+
+## Architectural Boundaries
+
+`internal/core` owns domain data handling and stable runtime contracts that do not require CLI or provider transport knowledge:
+
+- config defaults, loading, validation, redaction, and catalogs;
+- transcript and glossary schemas;
+- normalization and chunking;
+- output-schema encoding;
+- diagnostics artifact naming and run-directory helpers;
+- public process report shapes.
+
+`internal/framework` owns orchestration contracts and reusable runtime mechanics:
+
+- module and validator interfaces;
+- proposal generation, proposal application, and prompt context;
+- runner orchestration;
+- LLM scheduler, OpenAI-compatible adapter, redaction helpers, and diagnostics writers;
+- structured response schema registry;
+- process report and correction-ledger assembly.
+
+`internal/modules/*` owns module-specific correction stages. `internal/validators/*` owns built-in validator implementations, registry, chains, and execution-class metadata. `internal/prompts` owns embedded prompt assets and prompt metadata.
+
+`internal/cli` owns command parsing, exit codes, stdout/stderr behavior, config command behavior, filesystem input/output wiring, and top-level process orchestration. CLI concerns should not move into modules, validators, or schema logic.
+
+Tests should stay close to the behavior they protect. Shared test helpers are acceptable when they remove clear duplication without hiding module-specific behavior.
+
+## Modules and Validators
+
+Modules implement `contracts.TranscriptModule`. A module must provide:
+
+- a stable key;
+- a replacement policy;
+- a validator chain;
+- proposal generation from explicit request inputs.
+
+Module packages should stay separate. Do not collapse module-specific prompts, scope, or validation choices into a broad generic stage abstraction.
+
+Validators implement the shared validator contract and return one decision per candidate proposal. Deterministic validators and LLM-backed validators are both composable chain elements. Validator identity and execution class metadata are stable enough to affect ordering, diagnostics, reports, and correction-ledger classification.
+
+Future module or validator changes should preserve:
+
+- explicit inputs and outputs;
+- no hidden global state;
+- explicit config dependencies;
+- deterministic proposal index handling;
+- validation before final mutation;
+- stable reason codes and validator keys where already exposed.
+
+## LLM Integration and Concurrency
+
+LLM calls are external effects behind narrow contracts. Production structured completions use `contracts.StructuredLLMClient`; the implemented provider adapter is OpenAI-compatible HTTP code in `internal/framework/llm`.
+
+Structured response schemas are registered in `internal/framework/responseschema`. Provider-side schema enforcement is not a substitute for local validation: Audita still validates proposal structure, validator decision cardinality, and apply-time safety.
+
+Concurrency is bounded by configured scheduler limits:
+
+- total LLM concurrency;
+- proposal LLM concurrency;
+- validation LLM concurrency.
+
+The scheduler is context-aware and releases permits on success, failure, and cancellation. Runner code may collect section-level work concurrently, but transcript mutation is applied later in deterministic proposal-index order.
+
+Diagnostics for LLM interactions should be useful for debugging without leaking configured secrets. Use the existing redaction helpers and `llm.ConfiguredSecrets`.
+
+## State, Inputs, and Outputs
+
+Audita does not implement resume, checkpoint, manifest, or remote storage behavior. Runtime state is in memory plus per-run diagnostics artifacts written under the configured work directory.
+
+Transcript input accepts the implemented JSON forms documented in the public contract. Parsed source transcripts are normalized into Audita's internal transcript shape before chunking and module execution.
+
+Proposals and validator decisions are intermediate runtime data. Approved proposals are applied through `internal/framework/proposals`, which clones transcript state, orders by proposal index, and records applied or skipped changes.
+
+Transcript output is encoded through `internal/core/outputschema`. Reports and correction ledgers are machine-readable artifacts derived from runner outputs; their public shape should not be changed casually.
+
+## Configuration and CLI Boundaries
+
+Config behavior is owned by `internal/core/config`; command usage and process wiring are owned by `internal/cli`.
+
+`audita process` uses implemented precedence: defaults, config file, environment, then CLI flags. `config validate` validates defaults plus a file config and intentionally does not apply environment overrides. `config print-effective` applies defaults, file config, and environment overrides, then prints redacted JSON.
+
+Do not duplicate full CLI or config reference material here. Use [Configuration](../configuration.md), the README, and [Public contract](../architecture/public-contract.md) for current external behavior.
+
+When adding config fields or CLI flags, update:
+
+- config defaults, file/env/CLI application, and validation;
+- CLI flag extraction if applicable;
+- redaction when secrets are involved;
+- tests for precedence and source-specific behavior;
+- user-facing docs if external behavior changes.
+
+## Errors, Logging, and Diagnostics
+
+Errors should be phase-specific enough for CLI users and subprocess callers. The CLI writes human-readable errors to stderr and preserves transcript JSON-only stdout behavior on successful stdout output.
+
+Run diagnostics are best-effort after run-directory creation. Failed runs are retained. Successful run retention follows the implemented work-dir retention policy.
+
+Diagnostics and reports must not leak configured LLM secrets. Config redaction and LLM payload/error redaction are separate responsibilities and should remain separate.
+
+Process reports, diagnostics metadata, utilization diagnostics, and correction ledgers are part of the public contract. Prefer additive, compatible changes.
+
+## Testing Expectations
+
+Use targeted package tests for touched behavior and `go test ./...` for substantial changes.
+
+When changing modules, inspect or add:
+
+- package-local module tests under `internal/modules/*`;
+- prompt rendering or proposal-generation tests when prompt inputs change;
+- parity or release fixtures when public output behavior changes.
+
+When changing validators, inspect or add:
+
+- validator package tests;
+- registry and chain tests under `internal/validators`;
+- framework validator tests for batching, malformed output, diagnostics, and cardinality.
+
+When changing LLM integration or concurrency, inspect or add:
+
+- `internal/framework/llm` scheduler/client/redaction tests;
+- `internal/framework/runner` orchestration and utilization tests;
+- structured-output malformed classification tests.
+
+When changing config, CLI, schema, output, reports, or diagnostics, inspect or add:
+
+- `internal/core/config` tests;
+- CLI tests under `internal/cli`;
+- schema and output-schema tests under `internal/core`;
+- report, diagnostics, parity, and release-fixture tests.
+
+## Dependency Policy
+
+Audita should remain dependency-light. Prefer standard-library solutions for CLI parsing, HTTP, JSON, filesystem, synchronization, and tests.
+
+Third-party dependencies should be narrow, justified, and preferably de facto standard for their purpose. YAML parsing is the current direct dependency exception.
+
+Do not add broad frameworks for CLI, dependency injection, workflow orchestration, logging, or plugin systems without a concrete implemented need and focused tests.
+
+## Documentation Expectations
+
+Follow [Documentation Policy](./documentation.md). Architecture policy must stay concise and aligned with implemented behavior.
+
+Do not use architecture docs as changelogs. Do not describe planned modules, adapters, modes, persistence, or configuration unless they are implemented. Put future work under `docs/roadmap/`.
+
+## Architectural Invariants
+
+- Keep LLM transport behind `StructuredLLMClient` and framework adapter boundaries.
+- Keep correction modules narrowly scoped and package-separated.
+- Keep validators modular, composable, and identified by stable keys.
+- Keep CLI/config/filesystem concerns out of module and validator domain logic.
+- Preserve deterministic transcript mutation and output handling around nondeterministic LLM calls.
+- Keep LLM concurrency bounded, configurable, and observable where implemented.
+- Keep run diagnostics and reports redacted and machine-readable.
+- Keep public CLI, config, output-schema, diagnostics, report, prompt, module, and validator contracts stable unless a change is explicit and tested.
+- Prefer small shared helpers over broad rewrites.
+- Avoid new dependencies unless they are narrow and clearly justified.
+
+## Non-Goals
+
+- No plugin framework is implemented.
+- No generic workflow engine is implemented.
+- No resume, checkpoint, manifest, or remote storage system is implemented.
+- No multi-process service mode is implemented.
+- No provider SDK abstraction beyond the current structured LLM client contract and OpenAI-compatible HTTP adapter is implemented.

+# Go Project Documentation Policy
+
+## Purpose
+
+Project documentation must help four audiences:
+
+1. users who need to run the application;
+2. administrators/operators who need to configure and operate it;
+3. developers who need to understand and change it safely;
+4. LLM coding agents that need clear scope, boundaries, and invariants.
+
+Docs should be accurate, concise, task-oriented, and organized by audience. Prefer links to canonical docs over repetition.
+
+## Core Rules
+
+### 1. Keep docs concise
+
+Each document should cover a defined scope and only the essentials for that scope.
+
+Avoid:
+- long background explanations;
+- repeated reference material;
+- implementation detail in user-facing docs;
+- aspirational language outside roadmap docs;
+- verbose examples where one minimal example is clearer.
+
+### 2. Document only implemented behavior outside roadmap files
+
+Unimplemented, planned, aspirational, experimental, or future work may be described only under:
+
+- `docs/roadmap/`
+
+No other documentation file, including `README.md`, should describe code, features, modules, stages, commands, config fields, or behaviors that do not currently exist.
+
+If a feature is partial, non-roadmap docs may describe only the implemented portion and its current boundary.
+
+### 3. Use canonical homes
+
+Each type of information should have one canonical location.
+
+Canonical homes:
+
+- project purpose and quickstart: `README.md`
+- development principles: `docs/policy/architecture.md`
+- configuration reference: `docs/config.md`
+- CLI reference: `docs/cli.md`
+- operations and recovery: `docs/operations.md`
+- troubleshooting: `docs/troubleshooting.md`
+- implemented internals: `docs/internal/`
+- future work: `docs/roadmap/`
+- contributor workflow: `docs/policy/development.md`
+- copyable examples: `examples/`
+
+Other files should summarize briefly and link to the canonical source.
+
+### 4. Keep examples real
+
+Examples should be valid, maintained, and free of secrets.
+
+Where practical:
+- example configs should load successfully;
+- example commands should match real CLI syntax;
+- important examples should be covered by tests.
+
+## Documentation Profiles
+
+All projects require:
+
+- `README.md`
+- `docs/policy/architecture.md`
+
+Additional docs depend on the project.

+**Audience:** users, administrators, operators
+
+The README is the outward-facing project orientation page.
+
+It should include, in order:
+
+1. concise description;
+2. elevator pitch;
+3. shortest useful command or usage example;
+4. links to targeted docs.
+
+The README should be short. It is not a manual.
+
+The “shortest useful command” means the simplest command that performs the project’s core use case. (It does not mean `app --help`.)

+### docs/policy/architecture.md
+
+**Audience:** developers, LLM coding agents
+
+`docs/policy/architecture.md` is required for every project.

+- project shape;
+- core design principles;
+- package and boundary philosophy;
+- state/persistence philosophy, if applicable;
+- external integration philosophy, if applicable;
+- error-handling and logging principles;
+- testing expectations;
+- documentation expectations;
+- architectural invariants;

+
+The full configuration reference should be canonical.
+
+### docs/cli.md
+
+**Audience:** users, administrators, operators
+
+Required for CLI applications.
+
+It should include, in order:
+
+1. shortest useful command;

+4. common workflows;
+5. diagnostic or recovery commands, if applicable.
+
+Explain when commands are useful, not just their syntax.
+
+### docs/operations.md
+
+**Audience:** administrators, operators
+
+Required for applications that maintain state, support resume behavior, run multiple stages, write durable artifacts, use remote storage, or require recovery procedures.
+
+It should cover:

+- normal workflow;
+- filesystem layout;
+- remote storage layout, if applicable;
+- logs and manifests;
+- resume/retry behavior;
+- cleanup behavior;
+- archive/backup behavior;
+- safe recovery procedures;

+- relevant links.
+
+### docs/internal/
+
+**Audience:** developers, LLM coding agents
+
+Required for modular, staged, service-oriented, or orchestration projects.
+
+This directory describes implemented internal components. It is not the roadmap.

+7. skip/resume behavior, if applicable;
+8. failure behavior;
+9. tests to inspect before changing;
+10. architectural invariants.
+
+### docs/roadmap/
+
+**Audience:** maintainers, developers, LLM coding agents
+
+This is the only place for planned, future, aspirational, experimental, or unimplemented work.
+
+Roadmap docs should clearly distinguish:
+
+- proposed work;
+- accepted plans;
+- deferred ideas;
+- rejected ideas;
+- implementation prompts or task breakdowns, if useful.
+
+Roadmap docs should not be confused with current behavior.
+
+### docs/integrations/
+
+**Audience:** developers, LLM coding agents
+
+Required for projects that depend on external CLIs, APIs, services, protocols, or file formats where the integration contract is important to maintain.
+
+This directory contains concise, versioned reference notes for external integration contracts. It should document only the parts of the external system that this project actually uses.
+
+Use one file per integration where useful.
+
+## Examples Directory
+
+Projects with non-trivial configuration or workflows should include `examples/`.
+
+Useful examples include:
+
+- minimal working config;
+- production-oriented config;
+- full annotated config;
+- local development config;
+- remote/object-storage config;
+- minimal session/input file.
+
+Examples should be valid, maintained, tested when practical, and linked from relevant docs.
+
+## Security and Privacy
+
+Docs and examples must not include:
+
+- real API keys;
+- tokens;
+- passwords;
+- private keys;
+- private environment dumps;
+- sensitive user data;
+- raw private transcripts;
+- private infrastructure details unless intentionally public.
+
+Document secret-handling mechanisms, not actual secret values.
+
+## Maintenance Rules
+
+When docs change, verify the affected behavior.
+
+Where practical:
+
+- load example config files in tests;
+- test CLI examples or command parser behavior;
+- validate documented flags against real flags;
+- remove stale references;
+- update links after renames;
+- keep roadmap content out of non-roadmap docs.
+
+If documentation and code disagree, fix the documentation and/or open a roadmap item; do not leave aspirational behavior in current-behavior docs.
+
+Documentation is complete only when it matches the current code.
+
+## Documentation Change Checklist
+
+Before merging documentation changes, verify:
+
+- README is concise and orientation-focused.
+- `docs/policy/architecture.md` describes development principles.
+- Future work appears only under `docs/roadmap/`.
+- User-facing docs avoid unnecessary internals.
+- Developer-facing docs preserve boundaries and invariants.
+- Config examples match the schema.
+- CLI examples match real commands and flags.
+- Defaults appear in the canonical config reference.
+- No secrets or private data are included.
+- Links are accurate.

+# Audita Release Checklist
+
+Use this checklist before cutting a pre-1.0 or 1.0 release candidate.
+
+## Core test pass
+
+- Run:
+  - `go test ./...`
+- Confirm tests pass without live LLM credentials and without Python dependencies.
+
+## Config validation and precedence
+
+- Validate a representative config:
+  - `audita config validate --config <path>`
+- Inspect redacted effective config:
+  - `audita config print-effective --config <path>`
+- Confirm precedence behavior:
+  - defaults -> file config -> environment -> CLI.
+- Confirm default config search order:
+  - `/usr/local/etc/audita/config.yml` first, then `/etc/audita/config.yml`.
+- Confirm missing both default-path config files is non-fatal when `--config`/`AUDITA_CONFIG` are unset.
+
+## Output schema checks
+
+- Verify default output schema remains `bare-segments`.
+- Verify `--output-schema audita-v1` emits object payload with `schema` and `version`.
+- Verify unknown schema (for example `seriatim-intermediate`) fails clearly.
+
+## Subprocess contract checks
+
+- With `--output`, verify stdout is empty on success.
+- Without `--output`, verify stdout contains transcript JSON only.
+- Verify `--report-json` writes file output and does not write report JSON to stdout.
+- Verify failure stderr remains human-readable and includes diagnostics path when available.
+- Verify nonzero exit on failures.
+
+## Structured LLM checks
+
+- Verify runtime uses the Audita-owned OpenAI-compatible adapter.
+- Verify structured response schemas are attached via `response_format.type=json_schema`.
+- Verify diagnostics metadata includes structured schema `id/version/name/sha256`.
+- Verify provider output is still locally decoded/validated before use.
+- Verify malformed module-stage structured payloads degrade to warnings/rejections instead of failing the run.
+
+## Report and diagnostics schema checks
+
+- Verify report metadata fields:
+  - `report_schema_name`
+  - `report_schema_version`
+  - `output_schema`
+  - `config_version` when file config is used.
+- Verify diagnostics artifact references exist in reports:
+  - transcript/normalization/chunking/invocation/effective-config artifacts
+  - utilization diagnostics artifact
+  - correction ledger artifact
+  - error log on failures.
+
+## Redaction checks
+
+- Verify secrets are redacted from:
+  - `effective-config.json`
+  - run-dir and `--report-json` reports
+  - LLM request/response/error diagnostics payloads.
+- Verify no API keys/bearer tokens leak into fixtures or outputs.
+
+## Prompt and validator metadata checks
+
+- Verify prompt metadata appears in LLM request metadata diagnostics:
+  - `prompt_id`, `prompt_version`, `prompt_source`, `embedded_path`, `sha256`.
+- Verify stable validator keys appear in report decisions/rejections.
+- Verify module warning records appear in reports for malformed proposal-generation payloads and malformed validator batches.
+- Verify built-in validator chains resolve and execute for default and explicit module runs.
+
+## Utilization diagnostics checks
+
+- Verify `utilization-diagnostics.json` exists on successful runs.
+- Verify partial utilization artifact behavior on controlled failure paths.
+- Verify utilization fields are structurally present and nonnegative:
+  - effective concurrency
+  - run timing
+  - module timing summaries
+  - per-validator timing summaries.
+
+## Correction ledger checks
+
+- Verify `correction-ledger.json` exists on successful runs.
+- Verify report references ledger artifact path.
+- Verify ledger dispositions include applied/rejected and skipped/failed where exercised.
+- Verify validator rejection and proposal-application skip remain distinct.
+
+## Pipeline behavior checks
+
+- Verify default full pipeline run remains:
+  - `glossary`, `homophones`, `glossary`, `spoken_word`, `grammar`
+  - with deterministic repeated instance naming (`glossary_1`, `glossary_2`).
+- Verify explicit module runs (`--modules`) still work.
+
+## Failure and cancellation checks
+
+- Verify controlled failure paths retain diagnostics and produce best-effort failure reports.
+- Verify malformed proposal-generation payloads keep exit code `0`, keep stderr empty on success, and record warnings in reports/diagnostics.
+- Verify malformed validator payloads reject only the affected batch and do not fail the module.
+- Verify timeout/cancellation paths exit nonzero, do not hang, and retain failure diagnostics when initialized.
+
+## Release fixture/idempotence checks
+
+- Run release fixtures (`internal/cli/testdata/release`) through `go test ./...`.
+- Confirm fixture checks cover:
+  - must-apply and must-not-apply expectations
+  - protected-term survival
+  - report and diagnostics contracts
+  - output-schema checks
+  - prompt/schema metadata diagnostics
+  - utilization/ledger artifacts
+  - idempotence-oriented second pass no-op behavior with deterministic fake responses.
+
+## Deferred-feature guardrail
+
+- Confirm release docs do not claim support for deferred items:
+  - filesystem prompt overrides
+  - user-configurable validator chains
+  - arbitrary user-supplied output schemas
+  - resume/start-at/stop-after execution
+  - diff/check/propose-only modes
+  - generated transcript descriptions enabled by default
+  - interactive review UI
+  - UI/server wrapper
+  - provider benchmarking harness.

+# Documentation Roadmap
+
+## Purpose
+
+This roadmap defines the work required to bring Audita documentation into compliance with `docs/policy/documentation.md` and the implemented architecture described by `docs/policy/architecture.md`.
+
+This is an implementation plan for future documentation cleanup. It does not rewrite the main documentation. Future implementation passes should document only current behavior outside `docs/roadmap/`, keep planned or unimplemented work in roadmap files, and verify claims against repository code and tests rather than stale documentation.
+
+## Repository Documentation Inventory
+
+- `README.md`: keep and rewrite. It should remain the project orientation and quickstart, but it currently carries too much reference material and includes stale links such as `docs/diagnostics.md`, `docs/structured-llm.md`, and `docs/subprocess-operations.md`.
+- `docs/policy/documentation.md`: keep and lightly update only if needed. It is the canonical documentation policy.
+- `docs/policy/architecture.md`: keep and lightly verify after the migration. It is the canonical architecture policy for developers and coding agents.
+- `docs/development.md`: move and rewrite as `docs/policy/development.md`. Contributor workflow belongs under `docs/policy/`.
+- `docs/configuration.md`: move and rewrite as `docs/config.md`. Configuration reference belongs at the canonical config path.
+- `docs/architecture.md`: merge or delete after the internal docs are created. Its useful content should become an internal overview or links to canonical internal docs.
+- `docs/architecture/architecture.md`: split and rewrite into `docs/internal/overview.md` and `docs/internal/pipeline.md`.
+- `docs/architecture/public-contract.md`: split across `docs/cli.md`, `docs/config.md`, `docs/operations.md`, and integration docs where applicable.
+- `docs/architecture/diagnostics.md`: split across `docs/operations.md` and `docs/internal/diagnostics-reporting.md`.
+- `docs/architecture/structured-llm.md`: split across `docs/internal/llm-runtime.md` and `docs/integrations/openai-compatible-llm.md`.
+- `docs/architecture/validators.md`: move and rewrite as `docs/internal/validators.md`.
+- `docs/architecture/prompts.md`: move and rewrite as `docs/internal/prompts.md`; remove deferred and unimplemented prompt override material.
+- `docs/architecture/output-schemas.md`: move and rewrite as `docs/internal/output-schemas.md`; remove deferred or unimplemented schema material such as `seriatim-intermediate`.
+- `docs/documentation/policy.md`: merge/delete in favor of `docs/policy/documentation.md`. It duplicates policy material in a noncanonical location.
+- `docs/integration/subprocess-operations.md`: move and rewrite as `docs/integrations/subprocess.md`.
+- `docs/release-checklist.md`: merge current-behavior checks into `docs/policy/development.md` or move to a clearer policy/internal location; remove pre-release or deferred-feature guardrail language from non-roadmap docs.
+- `docs/roadmap/audit.md`: currently deleted in the worktree. Treat this as unrelated state unless a later task explicitly restores or updates it.
+- `docs/roadmap/implementation.md`: currently deleted in the worktree. Treat this as unrelated state unless a later task explicitly restores or updates it.
+- `examples/`: create new. No examples directory is currently present, but policy expects copyable examples when practical.
+
+## Policy Compliance Assessment
+
+Required or expected canonical documents are missing:
+
+- `docs/cli.md`
+- `docs/config.md`
+- `docs/operations.md`
+- `docs/internal/`
+- `docs/policy/development.md`
+- `examples/`
+
+Recommended documents that should be added:
+
+- `docs/troubleshooting.md`
+- `docs/integrations/openai-compatible-llm.md`
+- `docs/integrations/transcript-glossary-files.md`
+
+Documents in the wrong canonical home:
+
+- `docs/configuration.md` should become `docs/config.md`.
+- `docs/development.md` should become `docs/policy/development.md`.
+- `docs/integration/` should become `docs/integrations/`.
+- Implemented internal architecture content under `docs/architecture/` should move to `docs/internal/`.
+- `docs/documentation/policy.md` should merge/delete in favor of `docs/policy/documentation.md`.
+
+Content that should not remain outside `docs/roadmap/`:
+
+- Deferred or unimplemented output schema content in `docs/architecture/output-schemas.md`.
+- Deferred or unimplemented prompt override, generated transcript description, and report prompt ledger content in `docs/architecture/prompts.md`.
+- Pre-release or future-feature guardrail language in `docs/release-checklist.md`, unless moved to roadmap or rewritten as current contributor workflow.
+
+Examples and links:
+
+- `examples/` is missing.
+- README links to nonexistent documentation paths.
+- Links to `docs/configuration.md`, `docs/development.md`, and `docs/integration/` should be updated after canonical moves.
+- A repository-wide link/path check should be part of final validation.

+
+## File-by-File Rewrite Guidance
+
+### README
+
+Cover project purpose, shortest useful command, build/test basics, and links to canonical docs. Avoid full CLI flag lists, full config schema, diagnostics reference, module internals, and architectural history. Link to `docs/cli.md`, `docs/config.md`, `docs/operations.md`, `docs/troubleshooting.md`, and policy docs after those files exist. Do not carry forward stale links to nonexistent `docs/diagnostics.md`, `docs/structured-llm.md`, or `docs/subprocess-operations.md`.
+
+### `docs/config.md`
+
+Rewrite from `docs/configuration.md`. Cover path resolution, precedence, YAML schema, env overrides, CLI override relationship, validation, and secrets. Link to `docs/cli.md` for command syntax and to examples for copyable files. Inspect `internal/core/config/*` and config tests. Avoid duplicating every CLI flag except where needed to explain precedence.
+
+### `docs/cli.md`
+
+Build from `internal/cli/run.go`, `internal/cli/process_flags.go`, and CLI tests. Cover `process`, `config validate`, and `config print-effective`. Include implemented output destinations and subprocess-friendly behavior. Link to `docs/config.md` for configuration details and `docs/operations.md` for diagnostics and reports. Avoid documenting unsupported command aliases or future commands.
+
+### `docs/operations.md`
+
+Merge operational material from diagnostics and subprocess docs. Cover run directories, diagnostics artifacts, reports, correction ledger, retention, output/report writes, and safe failure inspection. Inspect `internal/core/diagnostics`, `internal/framework/processreport`, and CLI tests. State that resume, checkpoint, and remote storage are not implemented only if needed to avoid user confusion.
+
+### `docs/troubleshooting.md`
+
+Create concise symptom/cause/inspect/fix entries for implemented failures. Inspect config validation tests, schema tests, LLM adapter tests, reporting tests, and CLI integration tests. Avoid broad operational advice that is not supported by the repository.
+
+### `docs/policy/development.md`
+
+Move and rewrite from `docs/development.md`. Cover setup, package layout, tests, conventions, and how to add config fields, CLI flags, modules, validators, docs, and examples. Merge any still-useful current-behavior release checks from `docs/release-checklist.md`. Avoid roadmap, pre-1.0 history, and deferred-feature guardrail language.
+
+### `docs/internal/*`
+
+Move implemented architecture details out of `docs/architecture/*`. Keep these docs concise and developer-facing. Remove deferred or unimplemented sections such as `seriatim-intermediate`, prompt overrides, generated transcript descriptions, report-level prompt ledgers, plugin systems, workflow engines, resume, and remote storage.
+
+### `docs/integrations/subprocess.md`
+
+Move from `docs/integration/subprocess-operations.md`. Keep stdout/stderr, file outputs, exit behavior, diagnostics/report handling, and parent-process guidance that matches current CLI behavior. Do not document non-existent streaming APIs.
+
+### `docs/integrations/openai-compatible-llm.md`
+
+Derive from implemented `internal/framework/llm` behavior and the current structured LLM architecture doc. Cover OpenAI-compatible chat completions, `response_format.type=json_schema`, retries, timeouts, and redaction. Do not claim support for provider SDKs or non-OpenAI-compatible APIs.
+
+### `docs/integrations/transcript-glossary-files.md`
+
+Create from implemented schema loading and validation. Cover the file shapes accepted by Audita and link to examples. Do not invent a formal external schema version beyond what the code validates.
+
+### `docs/documentation/policy.md`
+
+Delete after verifying any unique useful policy content is already in `docs/policy/documentation.md`. Do not keep two documentation policy homes.
+
+### `docs/release-checklist.md`
+
+Either merge current-behavior contributor checks into `docs/policy/development.md` or move a concise checklist to a clearer policy/internal location. Remove future-feature or deferred-work guardrails from non-roadmap documentation.
+
+## Examples Plan
+
+Create maintained, non-secret examples only for implemented behavior.
+
+### `examples/minimal-config.yml`
+
+- Purpose: smallest useful config with `version: 1`, output schema, and `api_key_env`.
+- Expected validity check: `go run ./cmd/audita config validate --config examples/minimal-config.yml`.
+- Link from: `README.md`, `docs/config.md`, `docs/cli.md`.
+
+### `examples/production-config.yml`
+
+- Purpose: fuller config showing modules, LLMs, concurrency, chunking, normalization, thresholds, context, and diagnostics.
+- Expected validity check: `go run ./cmd/audita config validate --config examples/production-config.yml`.
+- Link from: `docs/config.md`.
+
+### `examples/tiny-transcript.json`
+
+- Purpose: small copyable transcript input for CLI examples and schema documentation.
+- Expected validity check: schema tests or a no-live-LLM CLI parser path if practical.
+- Link from: `README.md`, `docs/cli.md`, `docs/integrations/transcript-glossary-files.md`.
+
+### `examples/tiny-glossary.yaml`
+
+- Purpose: small copyable glossary input for CLI examples.
+- Expected validity check: schema tests or a no-live-LLM CLI parser path if practical.
+- Link from: `README.md`, `docs/cli.md`, `docs/integrations/transcript-glossary-files.md`.
+
+Do not add examples for resume, remote storage, prompt overrides, plugin systems, UI/server mode, unsupported output schemas, or other unimplemented behavior.
+
+## Internal Documentation Plan
+
+### Pipeline
+
+- Path: `docs/internal/pipeline.md`
+- Purpose: document the implemented transcript processing pipeline.
+- Inputs and outputs: normalized transcript, sections, configured module specs, proposal results, validation results, runner output.
+- Boundaries: runner orchestrates; modules propose; validators filter; accepted proposals are applied deterministically.
+- Config fields used: modules, output schema, chunking, normalization, thresholds, concurrency, context, diagnostics.
+- Adapters used: LLM client through framework contracts; filesystem/reporting through CLI and diagnostics boundaries.
+- Failure behavior: module and validator warnings, rejected proposals, run/report error status.
+- Tests to inspect: runner tests, proposal generation tests, CLI parity and release fixture tests.
+- Architectural invariants: keep nondeterministic LLM effects isolated from deterministic transcript state handling.
+
+### Modules
+
+- Path: `docs/internal/modules.md`
+- Purpose: document implemented correction modules and their contracts.
+- Inputs and outputs: `contracts.ProposalRequest`, module proposals, warnings, replacement policies.
+- Boundaries: one package per module; prompt assets remain module-specific; shared framework plumbing stays outside module packages.
+- Config fields used: configured module keys, LLM settings, chunking/context where applicable.
+- Adapters used: LLM client only through contracts and proposal generation framework.
+- Failure behavior: proposal warnings and malformed LLM output handling as implemented.
+- Tests to inspect: `internal/modules/...` and proposal generation tests.
+- Architectural invariants: keep module scope narrow and avoid hidden global state.
+
+### Validators
+
+- Path: `docs/internal/validators.md`
+- Purpose: document validator composition and decision handling.
+- Inputs and outputs: candidate proposals, validator decisions, rejection reasons, warnings.
+- Boundaries: validator registry and chains live in `internal/validators`; runtime mechanics live in `internal/framework/validators`.
+- Config fields used: thresholds, validation LLM settings, validation concurrency, validation prompt limits.
+- Adapters used: LLM-backed validators use the LLM contract rather than direct transport.
+- Failure behavior: rejected proposals, warning behavior, malformed output policy.
+- Tests to inspect: validator registry, chain, batching, malformed output, protected terms, and LLM validator tests.
+- Architectural invariants: validators remain modular and composable.
+
+### LLM Runtime
+
+- Path: `docs/internal/llm-runtime.md`
+- Purpose: document structured LLM calls and bounded scheduling.
+- Inputs and outputs: structured prompt requests, response schemas, parsed responses, scheduler permit results, diagnostics metadata.
+- Boundaries: transport stays behind `StructuredLLMClient`; scheduler manages permits; response schema registry owns schema metadata.
+- Config fields used: model, base URL, API key, timeout, retries, total/proposal/validation concurrency, validation max prompt tokens.
+- Adapters used: OpenAI-compatible HTTP adapter.
+- Failure behavior: retries, timeout/context handling, malformed structured output handling, redacted errors.
+- Tests to inspect: LLM client, scheduler, redaction, response schema, structured output tests.
+- Architectural invariants: keep concurrency bounded and explicit; do not leak secrets in diagnostics.
+
+### Diagnostics and Reporting
+
+- Path: `docs/internal/diagnostics-reporting.md`
+- Purpose: document diagnostics artifacts, process reports, and correction ledger generation.
+- Inputs and outputs: run directory artifacts, diagnostics metadata, process report JSON, correction ledger entries.
+- Boundaries: diagnostics owns artifact names and metadata; processreport maps runner output to reporting structures; CLI chooses output destinations.
+- Config fields used: work dir, work-dir retention, transcript description.
+- Adapters used: filesystem through diagnostics/CLI boundaries.
+- Failure behavior: report status/error mapping and artifact write errors as implemented.
+- Tests to inspect: diagnostics tests, processreport tests, CLI report fixture tests.
+- Architectural invariants: preserve diagnostics filenames and report JSON shape unless intentionally changed and documented.
+
+### Prompts
+
+- Path: `docs/internal/prompts.md`
+- Purpose: document implemented prompt registry, embedded assets, and metadata.
+- Inputs and outputs: prompt identifiers, prompt asset content, rendered prompt payloads, diagnostic metadata.
+- Boundaries: prompt assets remain owned by module/framework areas that use them; no filesystem override mechanism is implemented.
+- Config fields used: transcript description/context where applicable.
+- Adapters used: none directly; prompts are consumed by LLM-backed framework code.
+- Failure behavior: missing or malformed embedded prompt assets should surface through tests or runtime errors as implemented.
+- Tests to inspect: prompt registry and module prompt tests.
+- Architectural invariants: keep prompt metadata consistent with diagnostics.
+
+### Output Schemas
+
+- Path: `docs/internal/output-schemas.md`
+- Purpose: document implemented output schema registry and report/output relationship.
+- Inputs and outputs: configured output schema key, validated schema support, emitted transcript output.
+- Boundaries: output schema registry lives in `internal/core/outputschema`; config validation consumes registry support.
+- Config fields used: output schema.
+- Adapters used: none directly.
+- Failure behavior: unsupported schema keys fail validation.
+- Tests to inspect: output schema and config validation tests.
+- Architectural invariants: do not document unsupported schemas as current behavior.
+
+## Integration Documentation Plan
+
+### `docs/integrations/subprocess.md`
+
+- External system or contract: parent process invoking the `audita` CLI.
+- Current usage in Audita: `audita process` writes output/report files and emits subprocess-friendly diagnostics and errors.
+- Version or compatibility notes: document only the current CLI behavior and implemented exit behavior.
+- What to document: invocation model, command examples, output files, report JSON path, stderr/stdout expectations, diagnostics, exit codes.
+- What not to document: streaming protocols, server mode, remote job control, resume APIs.
+
+### `docs/integrations/openai-compatible-llm.md`
+
+- External system or contract: OpenAI-compatible chat completions endpoint using JSON schema response format.
+- Current usage in Audita: configured primary and validation LLM clients issue structured chat completion requests with retries/timeouts and redaction.
+- Version or compatibility notes: document compatibility based on request behavior in `internal/framework/llm`, not provider marketing claims.
+- What to document: endpoint configuration, authentication, request/response expectations, `response_format.type=json_schema`, retries, timeouts, redaction.
+- What not to document: unsupported provider SDKs, non-OpenAI-compatible APIs, unimplemented model-routing features.
+
+### `docs/integrations/transcript-glossary-files.md`
+
+- External system or contract: transcript JSON and glossary YAML files accepted as inputs.
+- Current usage in Audita: CLI loads transcript and glossary files before processing and validates their shape through core schema code.
+- Version or compatibility notes: document implemented fields and validation behavior only.
+- What to document: accepted file shapes, required/optional fields, common validation errors, tiny examples.
+- What not to document: a formal versioned external schema that the code does not enforce.
+
+## Recommended Implementation Sequence
+
+### Stage 1: Roadmap Creation
+
+- Goal: create this documentation roadmap.
+- Files to create/update/delete/move: create `docs/roadmap/documentation.md` only.
+- Repository areas to inspect: documentation policy, architecture policy, existing docs, CLI/config/package/test layout.
+- Acceptance criteria: roadmap is action-oriented, staged, and limited to future documentation work.
+- Suggested validation commands: `git diff --check -- docs/roadmap/documentation.md`.
+- One prompt: yes.
+
+### Stage 2: Canonical Layout and README Links
+
+- Goal: establish canonical paths and remove obvious stale links without rewriting all content.
+- Files to create/update/delete/move: create target directories, move/rewrite shells for `docs/config.md`, `docs/policy/development.md`, `docs/integrations/subprocess.md`, and update README links; remove old duplicates only after content is preserved.
+- Repository areas to inspect: docs policy, README, moved docs.
+- Acceptance criteria: canonical paths exist; README does not link to nonexistent docs; old paths are either redirected by content moves or removed.
+- Suggested validation commands: `rg "docs/(diagnostics|structured-llm|subprocess-operations)\\.md" README.md docs`; `rg "docs/configuration\\.md|docs/development\\.md|docs/integration/" README.md docs`.
+- One prompt: yes.
+
+### Stage 3: README and CLI Reference
+
+- Goal: make README concise and create complete `docs/cli.md`.
+- Files to create/update/delete/move: `README.md`, `docs/cli.md`.
+- Repository areas to inspect: `cmd/audita/main.go`, `internal/cli/run.go`, `internal/cli/process_flags.go`, CLI tests.
+- Acceptance criteria: README is orientation only; all implemented commands and flags are covered in `docs/cli.md`; examples match parser behavior.
+- Suggested validation commands: `go test ./internal/cli ./cmd/audita`; stale-link grep checks.
+- One prompt: yes.
+
+### Stage 4: Config Reference and Examples
+
+- Goal: rewrite `docs/config.md` and add maintained copyable examples.
+- Files to create/update/delete/move: `docs/config.md`, `examples/minimal-config.yml`, `examples/production-config.yml`, `examples/tiny-transcript.json`, `examples/tiny-glossary.yaml`; remove `docs/configuration.md` after migration.
+- Repository areas to inspect: `internal/core/config/*`, config tests, schema tests.
+- Acceptance criteria: config reference matches implemented defaults, precedence, env vars, validation, and secrets; examples contain no secrets and validate where practical.
+- Suggested validation commands: `go test ./internal/core/config`; `go run ./cmd/audita config validate --config examples/minimal-config.yml`; `go run ./cmd/audita config validate --config examples/production-config.yml`.
+- One prompt: yes.
+
+### Stage 5: Operations and Troubleshooting
+
+- Goal: create operational and troubleshooting references.
+- Files to create/update/delete/move: `docs/operations.md`, `docs/troubleshooting.md`.
+- Repository areas to inspect: `internal/core/diagnostics`, `internal/framework/processreport`, `internal/core/reporting`, CLI failure/report tests.
+- Acceptance criteria: implemented artifacts, retention, reports, correction ledger, and failure inspection are documented; no resume or remote-storage claims.
+- Suggested validation commands: `go test ./internal/core/diagnostics ./internal/framework/processreport ./internal/cli`.
+- One prompt: yes.
+
+### Stage 6: Internal Architecture Docs Migration
+
+- Goal: move implemented architecture details into `docs/internal/` and remove roadmap content from non-roadmap docs.
+- Files to create/update/delete/move: `docs/internal/overview.md`, `docs/internal/pipeline.md`, `docs/internal/modules.md`, `docs/internal/validators.md`, `docs/internal/llm-runtime.md`, `docs/internal/diagnostics-reporting.md`, `docs/internal/prompts.md`, `docs/internal/output-schemas.md`; migrate/delete relevant `docs/architecture/*`.
+- Repository areas to inspect: `internal/core`, `internal/framework`, `internal/modules`, `internal/validators`, `internal/prompts`.
+- Acceptance criteria: internal docs document implemented behavior only; deferred or unimplemented content appears only under `docs/roadmap/`.
+- Suggested validation commands: `go test ./internal/framework/llm ./internal/framework/runner`; `go test ./internal/validators/...`; `go test ./internal/modules/...`; `rg "deferred|not implemented|future|planned|experimental|aspirational" docs --glob '!docs/roadmap/**'`.
+- One prompt: split if needed into pipeline/modules/validators and LLM/diagnostics/prompts/output schemas.
+
+### Stage 7: Integration Docs
+
+- Goal: create external contract docs for implemented integrations.
+- Files to create/update/delete/move: `docs/integrations/subprocess.md`, `docs/integrations/openai-compatible-llm.md`, `docs/integrations/transcript-glossary-files.md`; remove `docs/integration/` after migration.
+- Repository areas to inspect: CLI behavior, `internal/framework/llm`, `internal/core/schema`, integration-related tests.
+- Acceptance criteria: integration docs describe actual external contracts and do not claim unsupported APIs.
+- Suggested validation commands: `go test ./internal/cli ./cmd/audita`; `go test ./internal/framework/llm`; schema package tests.
+- One prompt: yes.
+
+### Stage 8: Development Policy and Duplicate Cleanup
+
+- Goal: finish contributor workflow docs and remove duplicate policy locations.
+- Files to create/update/delete/move: `docs/policy/development.md`, `docs/documentation/policy.md`, `docs/release-checklist.md`, any remaining old architecture/config/development paths.
+- Repository areas to inspect: policy docs, development docs, test layout, final documentation tree.
+- Acceptance criteria: one canonical documentation policy, one canonical development workflow, no duplicate or stale canonical-home references.
+- Suggested validation commands: `find docs -type f | sort`; grep checks for old paths and duplicate policy paths.
+- One prompt: yes.
+
+### Stage 9: Final Documentation Validation
+
+- Goal: repository-wide documentation review after migration.
+- Files to create/update/delete/move: all documentation and examples touched by prior stages only as needed for fixes.
+- Repository areas to inspect: final docs tree, README, examples, code-backed docs.
+- Acceptance criteria: canonical docs exist, stale docs removed, examples valid, no unimplemented claims outside roadmap, Go tests pass.
+- Suggested validation commands: `go test ./...`; all grep/link checks in this roadmap; example validation commands.
+- One prompt: yes.
+
+## Validation Plan
+
+No markdown or documentation linter configuration was found. Use repository behavior tests, whitespace checks, grep checks, and manual review.
+
+Automated checks:
+
+- `git diff --check`
+- `go test ./internal/core/config`
+- `go test ./internal/cli ./cmd/audita`
+- `go test ./internal/core/diagnostics ./internal/framework/processreport`
+- `go test ./internal/framework/llm ./internal/framework/runner`
+- `go test ./...`
+
+Example checks after examples exist:
+
+- `go run ./cmd/audita config validate --config examples/minimal-config.yml`
+- `go run ./cmd/audita config validate --config examples/production-config.yml`
+
+Recommended grep and path checks:
+
+- `rg "docs/(diagnostics|structured-llm|subprocess-operations)\\.md" README.md docs`
+- `rg "docs/configuration\\.md|docs/development\\.md|docs/integration/" README.md docs`
+- `rg "deferred|not implemented|future|planned|experimental|aspirational" docs --glob '!docs/roadmap/**'`
+- `find docs -type f | sort`
+- `find examples -type f | sort`
+
+Manual review:
+
+- Confirm README is concise and links to canonical docs.
+- Confirm CLI and config docs do not duplicate each other.
+- Confirm internal docs are developer-facing and not user manuals.
+- Confirm operations and troubleshooting docs describe current behavior only.
+- Confirm future work appears only under `docs/roadmap/`.
+- Confirm examples contain no secrets or private transcript data.
+
+## Open Questions
+
+No questions block the roadmap. Use these defaults unless a later implementation prompt says otherwise:
+
+- Use the canonical paths from `docs/policy/documentation.md`, even when that requires moving existing docs.
+- Treat `docs/configuration.md`, `docs/development.md`, `docs/integration/`, and `docs/architecture/*` as migration sources, not final homes.
+- Do not restore deleted roadmap files unless separately requested.
+- Prefer concise canonical docs over preserving historical wording from stale files.
