+### Audita Selection and Credentials
+
+`pipeline.audita.config_path` optionally passes an Audita v2 configuration file;
+when empty, Audita uses its own native config discovery. `overlay`,
+`proposal_profile`, and `validation_profile` are independent, optional Audita
+selectors. Empty or omitted strings add no command-line override. Narratio's
+selected pipeline overlay is never inferred as an Audita overlay, and Narratio
+does not create or validate Audita's backend or PromptKit profile files. Prepare
+them with [Audita's v2 migration guide](https://gitea.maximumdirect.net/eric/audita/src/tag/v2.0.0/docs/migrations/v2.md).
+
+Omit `modules` or set it to `null` to use Audita's configured default sequence.
+Set `modules: []` to run no correction modules. A nonempty list is passed in
+order, including repetitions. Narratio does not add a reporting or debug flag;
+Audita's external configuration controls those settings.
+
+`pipeline.audita.credentials` lists secret-reference names, not values. Narratio
+resolves every listed name during pipeline loading and forwards the captured
+nonempty value under that exact name to Audita. It does not inspect Audita's
+configuration to discover names or map them to aliases. Audita v2 resolves
+credentials for **all configured backends**, even ones not selected by the
+current profiles: list every named backend credential in the selected Audita
+configuration. An unauthenticated backend needs no reference. Omission, `null`,
+or `[]` forwards nothing. A Narratio overlay replaces the entire list, and
+`[]` clears it. See the [Audita integration contract](./integrations/audita.md)
+for the subprocess and redaction boundary.
+
+### Notarius Configuration Profile
+
+`pipeline.notarius.config_profile` optionally selects a Notarius ConfigKit
+configuration profile when extraction executes:
+
+```yaml
+notarius:
+  config_profile: downstream-economy
+```
+
+When the field is omitted or `null`, Narratio supplies no downstream profile
+selector and preserves Notarius's existing configuration-selection behavior.
+When present, Narratio forwards the exact string to Notarius, including an
+empty string or `default`, which explicitly select Notarius's composed base
+configuration. Notarius owns selector interpretation and validation; Narratio
+does not restrict profile names, resolve profile files, or rewrite the value.
+
+This selection is independent of Narratio's own `--overlay` selection. A
+Narratio overlay may explicitly select a differently named Notarius overlay,
+but Narratio never forwards its own overlay name automatically. It is also
+independent of `pipeline.notarius.credentials`: an overlay may change either or
+both fields according to the deployed Notarius configuration. See the
+[Notarius integration contract](./integrations/notarius.md) for invocation and
+failure behavior.
+
+### Notarius Credentials
+
+`pipeline.notarius.credentials` optionally lists environment-variable names
+to forward to the Notarius child process:
+
+```yaml
+notarius:
+  credentials: [OPENROUTER_API_KEY, ANTHROPIC_API_KEY]
+```
+
+The list contains variable names, not credential values. Those names must
+match the references used by the Notarius/PromptKit profiles that Notarius
+loads. Notarius owns profile lookup; Narratio neither infers those names nor
+remaps them. Omission, `null`, or `[]` forwards nothing. Each selected reference
+must resolve at pipeline load time through the process environment or existing
+secrets-directory bootstrap, even when Notarius is disabled, extract is outside
+the requested range, or a completed extraction can be reused.
+
+The Notarius child receives only Narratio's minimal execution environment plus
+these exact selected names and loaded values. Other credentials are not forwarded.
+Changing a value, name, presence, or absence does not invalidate extract's
+semantic resume evidence. The public names remain part of safe effective
+inspection, so renaming them may appear in `config diff` and change the effective
+configuration digest; rotating only their values does neither. An overlay
+replaces the whole list, including with `[]` to clear it.
+
+See the [Notarius integration contract](./integrations/notarius.md) for the
+delivery and redaction boundary.
+
+### Notarius Cache Controls
+
+`pipeline.notarius.resume` defaults to `false`. When true, an executed ordinary
+extraction passes `--resume`; the deployed Notarius configuration must already
+enable checkpoint recording and should select an explicit persistent checkpoint
+root. Narratio does not inspect or generate that configuration.
+
+`pipeline.notarius.chunk_cache` is empty by default, leaving Notarius's
+configured mode in control. A nonempty value must be `auto`, `bypass`, or
+`refresh` and is passed as `--chunk_cache`. Forced extraction takes precedence
+over both fields: it omits `--resume` and passes `--chunk_cache refresh`.
+Neither field changes Narratio's semantic extraction fingerprint, so changing
+them alone does not rerun an otherwise complete durable extraction.

 # Integration: Audita
 
-## Purpose
-Define the Audita adapter contract used by the `polish` stage.
+Narratio invokes Audita v2's `process INPUT --glossary PATH --output PATH`
+subprocess for `polish`. The configured timeout and parent cancellation bound
+execution. Narratio passes explicit `--config`, `--overlay`,
+`--proposal-profile`, `--validation-profile`, `--transcript-description`,
+`--output-schema`, and `--modules` only when selected. An omitted module list
+leaves Audita's default sequence in place; `modules: []` passes an explicit
+empty argument and runs no correction modules. Order and repetitions are kept.
+Narratio passes no debug, work-directory, or reporting flags, leaving those
+choices to Audita's own configuration.
 
-## External Boundary
+Audita owns its ConfigKit file, backend and profile definitions, native config
+discovery, and their validation. Narratio does not create an Audita
+configuration or infer downstream overlay/profile names from its own selected
+pipeline overlay. An empty Narratio Audita selector adds no CLI override.
+The [configuration reference](../config.md#audita-selection-and-credentials)
+owns Narratio's fields and defaults. Audita's
+[v2 migration guide](https://gitea.maximumdirect.net/eric/audita/src/tag/v2.0.0/docs/migrations/v2.md)
+owns its downstream file format.
 
-Narratio invokes `audita process` as a subprocess for each polish operation.
-The configured timeout and parent cancellation bound the invocation. Internal
-runner composition is documented in
-[the adapter implementation guide](../internal/adapters.md).
+Each name in `pipeline.audita.credentials` is a ConfigKit secret reference
+resolved when Narratio loads the pipeline. Narratio forwards only the selected
+names and their captured, nonempty values under those exact names, in the
+minimal child environment; it never maps them to a fixed alias or rereads the
+parent environment. Every name is registered for captured stdout/stderr and
+failure-diagnostic redaction. Audita resolves credentials for all configured
+backends, including unselected ones, so operators must list every backend
+credential that its selected configuration needs. The downstream files and
+provider output remain Audita's responsibility, outside Narratio's
+captured-stream redaction boundary.
 
-## Request Contract
-`PolishRequest` carries:
-- required transcript/glossary/output/work-dir paths;
-- optional report path (required when report mode is enabled);
-- generated config and stdout/stderr log paths;
-- optional per-invocation module override.
+The corrected transcript is the only canonical polish output. A successful
+invocation must produce a valid JSON transcript with a top-level `segments`
+array within Narratio's 64 MiB bound. Exit zero is accepted even if Audita's
+ordinary reports describe recoverable model errors or no corrections. Narratio
+does not parse report status, counts, or Markdown. It discovers only
+`errors.yml`, `recoveries.yml`, and `report.md` next to the requested output,
+each subject to a 16 MiB read bound. Missing reports are allowed, for example
+when Audita reporting is disabled externally. Available reports are diagnostic
+references, not canonical artifact outputs. See Audita's
+[ordinary output contract](https://gitea.maximumdirect.net/eric/audita/src/tag/v2.0.0/docs/integrations/output-files.md)
+for their schemas, and [operations](../operations.md) for placement and
+publication.
 
-The constructed runner owns static Audita settings: binary, timeout,
-credentials, default modules, model and endpoint settings, validation and output
-settings, report mode, and concurrency. The `polish` stage supplies only
-invocation-specific paths and may override modules for that invocation.
+On nonzero exit, Narratio preserves the original subprocess error and
+available run-local evidence; it never promotes a transcript merely because
+the file exists. The adapter returns safe paths, exit details, and selection
+metadata on failure. Narratio's `audita.generated.v2` YAML records the
+invocation, including arguments, paths, and credential names but never values;
+it is a diagnostic record, not a generated Audita config file.
 
-## Result Contract
-`PolishResult` returns:
-- processed transcript path;
-- optional report path;
-- work dir and generated-config/log paths;
-- exit code, duration, binary provenance;
-- adapter metadata map.
-
-## Validation and Failure Semantics
-Construction fails for invalid static config values, including:
-- empty binary;
-- non-positive timeout;
-- invalid base URL;
-- invalid output schema;
-- invalid work-dir retention value;
-- invalid concurrency values.
-
-Run fails for:
-- missing required request paths;
-- missing required credential env var when configured (`llm_api_key_env`);
-- subprocess execution failure;
-- invalid processed transcript JSON (`segments` array required);
-- invalid report JSON when reporting is enabled.
-
-Processed transcript JSON is limited to 64 MiB and optional report JSON to 16
-MiB. Both must be regular files without symlinked path components.
-
-Failure results still include output/log/config/exit metadata for diagnostics.
-
-## Deterministic Behavior
-- CLI args are built from runner config + request in a fixed order.
-- Generated invocation YAML (`audita.generated.v1`) is emitted when requested.
-- Manifest writes are stage-owned; adapter itself is stateless.

+
+After correcting the underlying problem, retry normally:
+
+```bash

+
+Narratio hashes the current prepared audio, validates recorded transcript JSON,
+checksum, size, and location, and calls WhisperX only for missing or obsolete

+speaker checksums or copy older JSON into the canonical directory to influence
+reuse.
+
+The first current Narratio invocation that selects transcribe for an older
+aggregate-only manifest retranscribes every current speaker once because the
+old record cannot prove which audio bytes produced each file. Subsequent runs
+reuse the new versioned evidence normally. The overall session-manifest schema

+a manifest after current Narratio writes the additive speaker fields; retain a

+
+Before using an affected local session with the new version:
+
+1. Stop Narratio activity for the session and back up its manifest.
+2. Rename only `effective_config.selected_profile` to `selected_overlay`, keeping
+   its `name` and `source`, or remove the retired informational member. If a
+   current `selected_overlay` member already exists, retain it and remove the
+   retired member rather than creating duplicate keys.
+3. Preserve the schema version, digest, stage records, checkpoint evidence,
+   output references, and other session state. Retry the intended command.
+
+This metadata is informational, not resume authority. Do not delete session
+progress or force all stages merely to perform this migration. Other unknown
+fields still require investigation rather than blanket removal.
+
+Do not edit immutable remote committed snapshots. Restoring an older snapshot
+with retired provenance requires a compatible previous Narratio version, followed
+by migration of the restored local manifest before using the new version.
+
+## Migrating Audita and Provider Credentials
+
+This is a breaking clean cutover to Audita v2. Narratio does not translate an
+Audita v1 configuration, retain old field aliases, or generate a downstream
+configuration. Update both the deployed Audita executable/configuration and
+the Narratio pipeline before running polish. Retired Narratio fields are
+rejected by strict configuration loading; account for this break when choosing
+a release version.
+
+| Previous Narratio setting | New ownership and selection |
+| --- | --- |
+| `audita.base_url` | Audita v2 `backends.<id>.endpoint` |
+| `audita.total_llm_concurrency`, `proposal_llm_concurrency`, `validation_llm_concurrency` | Audita v2 `backends.<id>.concurrency` and optional `queue_capacity`; backend capacity is shared across roles |

+| `audita.work_dir_retention`, `report` | Remove; Audita's external configuration owns diagnostics and reporting |
+
+An Audita configuration can also be selected through `audita.config_path`,
+and `audita.overlay` selects an Audita overlay independently of Narratio's
+`--overlay`. Narratio forwards no implicit provider key: a single provider-named
+secret source may be listed for both adapters, and an Audita-only backend key
+may be listed only for Audita. Audita resolves credentials for all configured

+# Agent Policy
+
+**Base Policy Version:** 1.1
+
+**Last Updated**: 2026-09-25
+
+## Purpose
+
+Agents working in this repository must read and adhere to the following house rules.
+
+## Implementation Discipline
+
+**KEY PRINCIPLES:** Write the simplest idiomatic code that satisfies the user's
+request. Do not implicitly strengthen requirements, restrictions, or guarantees
+beyond what the user actually requested.
+
+Simplify the mechanism, not the user's choices.
+
+**Keep implementation machinery proportionate.** Use straightforward,
+idiomatic code and introduce only the machinery needed to support the requested
+behavior and flexibility. Optimize for conceptual simplicity and
+maintainability, not for the fewest lines, fewest options, or narrowest product
+surface.
+
+**Do not invent restrictions.** Do not reject, prohibit, constrain, cap,
+harden, or otherwise narrow behavior unless required by the user, an explicit
+repository contract, or an unavoidable correctness constraint. Preserve
+operator and caller choice where policy has not been established. If an
+additional restriction appears advisable, present it as a decision rather than
+silently implementing it.
+
+A correctness constraint must follow from the requested behavior or an
+established invariant, not from the convenience of the chosen implementation.
+Explain the specific failure it prevents and why a less restrictive
+implementation cannot satisfy the contract.
+
+**Do not invent guarantees.** Do not strengthen public contracts, guarantees,
+or invariants beyond those expressly requested by the user.
+
+**Use the standard library.** For example: in almost every case, the best
+approach to copying files is to use the standard library. Writing custom code to
+implement power-loss protection at the application level, or to guard against
+bad actors with privileged and concurrent access to the host's filesystem,
+is wasteful, unnecessary, and not idiomatic. Stick to the simple, standard, and
+idiomatic approach unless another path is expressly requested by the user.
+
+**An implementation detail is not repository policy.** Tests and documentation
+must not elevate incidental behavior into a durable guarantee or restriction
+unless that behavior was expressly selected as part of the contract. Existing
+explicit contracts remain authoritative; changing or weakening one requires a
+deliberate decision rather than being inferred from this principle.
+
+Agent-authored plans, tests, documentation, and prior implementations are not
+evidence that an additional restriction was deliberately approved. Identify the
+authorizing requirement or decision; when that authority is unclear, surface
+the ambiguity rather than treating repetition as approval.
+
+Standard-library guidance does not authorize weakening Narratio's established
+filesystem, manifest, or publication contracts. Preserve them unless a deliberate
+decision changes them.
+
+## Git Commit Policy
+
+By default, create a commit after completing each coherent unit of work, using a
+concise, plain-English message describing what changed. This policy is standing
+authorization to create those local commits; a separate user request is not
+required. An explicit user instruction to leave work uncommitted takes precedence.
+
+A unit of work is a focused, reviewable outcome, including its relevant tests and
+documentation. Do not commit after every intermediate edit or create empty commits.
+Complete the appropriate validation before committing. If work is incomplete or
+validation is blocked, report that state rather than presenting it as completed.
+
+Before committing:
+
+1. Run `git status --short` and review the relevant diff, including any staged
+   changes. Identify changes that predate the current unit of work.
+2. Exclude secrets, local environment files, generated junk, and unrelated changes.
+3. Stage only the files or hunks belonging to the completed unit. Use `git add .`
+   only when every included change belongs to that unit. Do not disturb unrelated
+   staged or unstaged work.
+4. Review `git diff --staged` and run appropriate checks for the change. Do not
+   repeat checks already passed for unchanged content merely to create a commit.
+5. Review `git log --oneline -n 10` and use
+   `git commit -m "<concise plain-English commit message>"`.
+6. Report the commit identifier and any remaining uncommitted work.
+
+If the unit cannot be safely separated from pre-existing work, leave it uncommitted
+and explain the overlap rather than silently including that work. If a commit
+fails, preserve the changes and report the failure; do not bypass hooks.
+
+Default commit authorization does not authorize pushing, publishing, amending,
+resetting, reverting, or rewriting history. Those actions require a separate user
+instruction. Do not use `git commit -a` or `git commit --no-verify` to bypass the
+staging and validation discipline above.

+# Release Policy
+
+**Base Policy Version:** 1.0
+
+**Last Updated**: 2026-09-25
+
+## Purpose
+
+This policy defines the minimum requirements for selecting, validating,
+publishing, verifying, and correcting releases. Its goal is to make every
+release intentional, reproducible from an exact source revision, documented
+for consumers, and safe from retrospective replacement.
+
+The repository-specific commands that implement these requirements belong in
+`docs/release.md`. Historical release summaries belong in `docs/releases/`.
+Neither document may weaken this policy, including its explicit repository
+exceptions.
+
+## Release Model
+
+A release consists of:
+
+- one exact source commit reachable from the repository's primary branch;
+- one immutable version tag identifying that commit;
+- one version-matched, checked-in release note; and
+- every artifact, image, package, registry entry, or other deliverable the
+  repository declares for that release.
+
+The repository's primary branch is `main` unless an adopted policy documents
+an exception. A release candidate must be committed and pushed to that branch
+before its release tag is published.
+
+The source tag is the authoritative release identity. Published deliverables
+must be traceable to the tagged source and must agree with its version. A
+repository may publish source only. When it publishes additional deliverables,
+its release procedure must enumerate them and define how each is built,
+identified, published, and verified.
+
+Release automation may validate or publish a release only when its exact
+responsibility is documented. Automation must not silently change the source
+candidate, move a published tag, replace a published deliverable, or repair a
+release in place.
+
+## Versioning And Compatibility
+
+Stable releases use Semantic Versioning in the form `vMAJOR.MINOR.PATCH`, with
+no leading zeroes. Each version must be unused locally and in every configured
+remote or publication channel before publication begins.
+
+Unless an adopted policy explicitly supports and defines prereleases,
+prerelease versions are not permitted.
+
+For releases at or after `v1.0.0`:
+
+- a major release may make intentional incompatible changes;
+- a minor release may add backward-compatible behavior; and
+- a patch release may make backward-compatible fixes.
+
+Before `v1.0.0`, a minor release may change a documented public, operational,
+configuration, data, integration, or compatibility contract when the release
+note explains the impact and required consumer action. A patch release must
+not intentionally break those contracts within its minor line.
+
+A repository with additional compatibility promises must define them in its
+adopted policy or canonical contract documentation. A release note may explain
+a compatibility change, but it must not redefine the current compatibility
+contract.
+
+## Release Documentation
+
+Every release made under this policy must include
+`docs/releases/<version>.md` in the tagged source tree. The filename must use
+the complete version tag, and the document must begin with a title containing
+the product name and that exact version.
+
+Every new release note must contain these sections:
+
+```markdown
+# <Product> vMAJOR.MINOR.PATCH
+
+This release ...
+
+## Summary
+
+## Compatibility
+
+## Upgrade
+
+## Changes
+```
+
+Use an explicit statement such as "No action required" when a section has no
+substantive content.
+
+Release notes are immutable historical summaries. They should link to current
+canonical documentation for exact behavior. Every affected canonical document
+must be updated in the same candidate; a release note must not substitute for
+current documentation or defer required documentation changes.
+
+## Candidate Preparation And Validation
+
+Each repository must provide one documented release-check command or script
+that exercises the complete set of automated source-candidate gates. The
+repository-specific procedure must state all additional manual gates.
+
+The required gates are:
+
+- dependency or module hygiene appropriate to the language and ecosystem;
+- the complete deterministic, offline default test suite;
+- static analysis and linting used by the repository;
+- formatting and whitespace checks;
+- validation of maintained examples, configuration, schemas, generated
+  sources, and documentation commands where applicable;
+- review of changed local documentation links;
+- removal of obsolete roadmap documents under `docs/roadmap/` that describe
+  completed work included in the release; and
+- review for unintended files, generated output, credentials, private data,
+  and unrelated changes.
+
+## Publication Guards
+
+Immediately before publication, the maintainer or release automation must
+fetch the current primary branch and tags from the authoritative remote and
+verify all of the following:
+
+- the version has the required format and is not already published;
+- the current branch is the primary release branch;
+- the worktree and index are clean;
+- the current commit is the recorded, validated candidate;
+- the authoritative remote branch points to that same commit;
+- the matching release note exists in that commit and has the required title
+  and sections;
+- all required approvals and automated gates succeeded for that commit; and
+- no local or remote tag already uses the selected version.
+
+Create the version tag against the guarded commit and verify its target before
+publishing it. Publish only the exact intended ref and deliverables. Broad
+operations such as `git push --tags` are discouraged because they can publish
+unreviewed refs unrelated to the release.
+
+The repository-specific procedure must make these guards executable or give
+copyable commands for performing them.
+
+## Immutability And Correction
+
+Published version tags and published deliverables are immutable. Do not move,
+overwrite, recreate, or delete a published tag. Do not replace an artifact,
+image, package, checksum, signature, provenance statement, or release note
+under an already published version.
+
+If validation fails before publication, correct the candidate, rerun the
+complete gates, and repeat the publication guards. An unpublished local tag
+may be removed after confirming that it was never published or used by a
+release channel.
+
+If publication or post-publication verification reveals a defect, leave the
+published release intact. Correct the defect on the primary branch, choose a
+new patch version or other semantically appropriate new version, write a new
+matching release note, and perform the complete release procedure again.
+
+A distribution channel's supported yank, deprecation, or advisory mechanism
+may warn consumers away from a defective release, but it must not replace that
+release's contents or reuse its version.
+
+## Repository Release Procedure
+
+Every adopting repository must maintain `docs/release.md` as the canonical
+maintainer runbook for implementing this policy. It must define, in execution
+order:
+
+1. maintainer prerequisites and required access;
+2. version selection and compatibility review;
+3. release-note creation;
+4. candidate preparation and the complete validation command;
+5. candidate commit, push, and exact commit recording;
+6. publication guards;
+7. exact tag and deliverable publication commands;
+8. authoritative remote and consumer-facing verification; and
+9. failure handling and correction.
+
+The procedure should use copyable, fail-fast commands where practical. It must
+name the primary branch, authoritative remote, tag form, published
+deliverables, supported build targets, release automation responsibilities,
+and consumer verification path. It must link to this policy instead of
+restating or redefining its requirements.
+
+## Policy Exceptions
+
+### Tag-push completion and asynchronous deliverables
+
+Narratio's automated release responsibility ends when the exact intended tag is
+successfully pushed to `origin`. It must not wait for, poll, or check CI/Gitea
+results, download assets, or verify their checksums as a completion condition.
+Binary and checksum publication is asynchronous; consumer-facing inspection is
+optional follow-up, not a gate on the source release.
+
+This deliberately qualifies the base policy's complete-deliverable and
+post-publication verification requirements. CI reliability is outside the
+release command's scope; an unavailable publication service must not cause an
+automated releaser to wait indefinitely or claim to repair a published version.
+
+Compensating controls are complete local candidate validation (including supported
+cross-builds and a host version check), exact source/tag guards, immutable source
+tags, asynchronous build validation, and non-overwriting asset publication.
+Successful tag publication is not evidence that binary assets are available.
+Optional inspection and corrective-release procedures belong in
+[the release procedure](../release.md).
+
+### Authoritative publication scope
+
+Narratio's synchronous publication guards inspect the authoritative `origin`
+remote and its `main` branch, not every configured Git remote or a Gitea release
+entry. The command does not add release-service or registry availability checks.
+This qualifies the base policy's all-channel unused-version requirement.
+
+Other remotes are not Narratio release authorities, and Gitea asset publication
+is asynchronous. The compensating controls are local and origin tag uniqueness,
+exact candidate matching, and the publisher's non-overwrite settings. Any known
+already-published version or conflicting deliverable remains ineligible for
+reuse: choose a new version rather than bypassing guards. A future additional
+distribution channel requires deliberate policy/procedure updates.

 # Releasing Narratio
 
-This document is the maintainer procedure for creating a Narratio source and
-binary release. The synchronous release boundary is a successful push of one
-new tag to `origin`; Woodpecker and Gitea publication happen later and do not
-change that result.
+This is the maintainer runbook for the [Release Policy](policy/release.md).
+Its [explicit exceptions](policy/release.md#policy-exceptions) preserve the
+successful tag push as the automated responsibility boundary. Binary publication
+is asynchronous; later consumer-facing inspection is optional.
+
+## Prerequisites and publication scope
+
+Use a checkout on `main` with Git authentication permitting fetches and pushes
+to `origin`, the authoritative Git remote. Install Git, a POSIX shell, standard
+Unix build tools, and the Go toolchain below. Make required modules available
+before offline validation. No model/provider credentials are needed. Gitea
+publication credentials belong to CI's secret store, not the local command.
+
+Synchronous guards inspect local tags and `origin`, not every configured remote
+or Gitea release entry. Do not select a version known to have been published in
+any channel, even if these guards cannot see it.
 
 ## Go prerequisite

+# Narratio v2.0.0
+
+Narratio v2.0.0 replaces its configuration infrastructure with ConfigKit,
+simplifies the supported release platforms, and makes artifact definitions and
+their effective dependency graph directly inspectable.
+
+## Summary
+
+Pipeline roots now use ConfigKit v0.1.2 for strict YAML loading, explicit
+imports, fixed-path named profiles, provenance, defaults, and typed credential
+references. The recommended production layout keeps production values in the
+base, defines each ordinary artifact and artifact family in its own imported
+file, and keeps testing changes in `profiles/testing.yml`.
+
+Configured-artifact inputs now create their dependency edges automatically.
+`narratio config artifacts` reports the finalized concrete catalog, including
+generated party-family members, without loading a session or initializing
+runtime adapters.
+
+## Compatibility
+
+This is a breaking configuration and platform release. There is no runtime
+fallback for the retired Narratio composition/profile catalog, `pipeline.secrets`
+or `secrets.env_dir`, credential `_env` fields, or the previous YAML
+presence/default behavior. Defaults apply only to absent values; explicit empty,
+zero, false, and null values retain their typed meaning and may fail Narratio
+domain validation.
+
+The maintained binaries are Linux amd64, Linux arm64, and macOS arm64. Windows
+and macOS amd64 builds are no longer produced or supported. Existing v1 release
+notes remain historical descriptions of their releases.
+
+Inspection commands still avoid session, manifest, workspace, adapter, and
+remote-service activity, but they are not credential-free loaders: every
+explicit typed credential reference in the selected effective configuration must
+resolve; references replaced or removed by that profile need not resolve.
+Pipelines containing artifact families also require a campaign so the canonical
+party can be expanded.
+`config show` is a secret-safe review projection, not a promised reloadable
+authoring file.
+
+## Upgrade
+
+Migrate each operational bundle before running v2:
+
+1. Replace old composition syntax with root-owned
+   [`configkit.imports`](../config.md#pipeline-imports-and-profiles). Imports are
+   additive base sources; they do not override one another.
+2. Fold the old production overlay into the base pipeline. Move testing changes
+   to `profiles/testing.yml`; compare the two independent resolutions with
+   `narratio config diff default testing`.
+3. Follow the maintained
+   [`examples/production-testing`](../../examples/production-testing/pipeline.yml)
+   layout: one explicit artifact entry per `artifacts/<key>.yml` and one family
+   entry per `artifact-families/<key>.yml`. The map key, not the filename, is the
+   stable artifact identity.
+4. Move credential files to an untracked `secrets/` directory beside
+   `pipeline.yml`, or pass `--secrets-dir`. Rename S3 fields to `access_key_id`
+   and `secret_access_key`, and rename the Audita field to `llm_api_key`.
+5. For static S3 credentials, configure both S3 references (commonly
+   `OBJECT_STORAGE_KEY_ID` and `OBJECT_STORAGE_KEY`) and make them resolvable.
+   To use instance roles, workload identity, shared SDK files, or another AWS SDK
+   discovery provider, omit both references. A partial pair is invalid.
+6. Remove a `depends_on` entry when it only duplicates a
+   `narratio.artifact.<key>` input. Keep explicit entries that express ordering
+   without supplying the upstream output as an input.
+7. Review ConfigKit's stricter explicit-value/null semantics and correct values
+   that previously acquired defaults after being explicitly empty. Do not use
+   `config show` output as a source migration mechanism.
+8. Run `config validate`, `config show`, `config sources`, and `config artifacts`
+   with the same profile, campaign, and secrets selection intended for runtime.
+   Resolve the campaign-owned party whenever families are present.
+9. Update deployment and download automation to one of the three maintained
+   platform assets before removing the v1 binary.
+
+The [configuration reference](../config.md), [CLI reference](../cli.md), and
+[maintained examples](../../examples/README.md) are the canonical detailed
+guides.
+
+## Changes
+
+- Adopted ConfigKit v0.1.2 across pipeline, campaign, session, and party loading
+  while keeping Narratio domain validation and post-campaign expansion explicit.
+- Added ConfigKit imports and fixed `profiles/<name>.yml` pipeline overlays,
+  unified safe effective show/diff/digest projection, and source provenance.
+- Added invocation-scoped ConfigKit secrets-directory bootstrap and typed S3 and
+  Audita credential references without exposing resolved values.
+- Inferred, normalized, and validated configured-artifact input dependencies as
+  part of the one concrete graph consumed by analyze planning and resume logic.
+- Added `config artifacts` with stable concrete identities, definition sources,
+  effective dependencies, and generated family/party provenance.
+- Added the maintained production-base/testing-overlay artifact authoring layout.
+- Reduced release assets and active platform support to Linux amd64/arm64 and
+  macOS arm64.

+# Narratio v2.1.0
+
+This release adds explicit Notarius credential forwarding and cache reuse,
+with predictable forced regeneration and clearer artifact-development guidance.
+
+## Summary
+
+Narratio can pass one typed API-key reference to Notarius and opt into reuse of
+its accepted execution checkpoints. Stable, verified reference snapshots allow
+unchanged references to retain their cache identity across Narratio invocations.
+Configuration loading now uses ConfigKit v0.3.0.
+
+## Compatibility
+
+The new `notarius.llm_api_key`, `notarius.resume`, and `notarius.chunk_cache`
+fields are optional. Existing v2 configuration needs no schema migration.
+Configured credential references must resolve during configuration loading,
+even when extraction will not execute; omitted references add no requirement.
+
+Forced extraction now omits Notarius checkpoint loading and requests chunk-plan
+refresh. This includes `regenerate-artifacts`, which remains an alias for a
+forced run from extract through analyze. `analyze` continues to force analysis
+only, preserving extraction results and transcripts.
+
+Notarius v0.7.0 is the tested cache integration baseline, not an unconditional
+minimum-version gate. The executable must support the flags selected for the
+invocation, including `--chunk_cache refresh` for forced extraction. Reference
+bindings retain the contract introduced in Notarius v0.6.0. Receipt and artifact
+schemas are unchanged; reused producers may report zero production attempts.
+
+Supported release platforms remain Linux amd64/arm64 and best-effort macOS
+arm64. macOS validation is cross-compilation, not native runtime testing.
+
+## Upgrade
+
+No special migration is required for existing v2 configuration. To use the new
+features:
+
+- Declare `notarius.llm_api_key` with the environment-variable name expected by
+  the deployed Notarius profile, supplying its value through the existing
+  environment or secrets-directory mechanism.
+- Enable checkpoint recording in Notarius configuration before setting
+  Narratio's `notarius.resume: true`. Prefer explicit persistent Notarius cache
+  roots for service deployments. An optional `notarius.chunk_cache` overrides
+  its ordinary chunk-plan policy.
+- Expect an initial checkpoint miss when moving from old run-local reference
+  paths to stable session snapshots. No migration or deletion of old caches is
+  required. Force refreshes the current input's plan, not the whole cache.
+- Use `narratio analyze SESSION` for analysis-only iteration, and
+  `narratio regenerate-artifacts SESSION` when extraction should also be rebuilt.
+
+See [Configuration](../config.md), the
+[Notarius integration contract](../integrations/notarius.md), and
+[Artifact Development Workflows](../operations.md#artifact-development-workflows)
+for current details.
+
+## Changes
+
+- Upgraded ConfigKit from v0.1.2 to v0.3.0 and isolated pipeline-discovery tests
+  from machine configuration.
+- Added optional typed Notarius credentials, exact-name environment delivery,
+  safe configuration projections, and captured-stream redaction for custom names.
+- Added Notarius resume and chunk-cache controls with force taking precedence.
+- Added verified, content-addressed session reference snapshots that survive
+  ordinary run cleanup without becoming published artifacts.
+- Preserved relative-workspace support for snapshot delivery and confinement.
+- Kept credentials and cache-policy controls outside extract's semantic resume
+  identity, so operational changes alone do not invalidate completed results.
+- Added an opt-in real Notarius integration test using a local provider to
+  verify reuse, partial-failure recovery, and forced refresh without paid calls.

+# Narratio v2.1.1
+
+This release fixes configuration loading for publish rules that explicitly set
+requiredness while relying on a derived destination.
+
+## Summary
+
+Publish rules with a derivable source and omitted `dest` now load correctly
+whether `required` is omitted, explicitly true, or explicitly false. Previously,
+explicit requiredness could trigger ConfigKit's `resolve.unrecorded_change`
+diagnostic instead of accepting valid configuration.
+
+## Compatibility
+
+This is a backward-compatible bookkeeping correction. Publish schemas,
+destination derivation, requiredness defaults, and YAML syntax support are
+unchanged. Explicit destinations and explicit false values remain intact.
+No ConfigKit upgrade or publication/storage behavior change is involved.
+
+## Upgrade
+
+No special upgrade action or configuration migration is required. Operators
+need not add a derivable `dest`, remove explicit `required` values, or change
+flow-style YAML to block-style YAML. See the
+[configuration reference](../config.md#publish-configuration-summary).
+
+## Changes
+
+- Recorded derived publish destinations at ConfigKit's atomic sequence boundary
+  while retaining field-level resolution records.
+- Added real load/validation and safe effective-configuration regression coverage
+  for built-in and configured-artifact sources, explicit requiredness, and an
+  explicit destination that must remain unchanged.

+# Narratio v2.2.0
+
+This release adds resumable per-speaker transcription, replayable WhisperX
+uploads, and explicit Notarius configuration profile selection.
+
+## Summary
+
+Successfully checkpointed speaker transcripts survive later transcription
+failures. Ordinary retry reuses valid completed speakers and processes only the
+remaining work. WhisperX uploads can now be replayed by the HTTP transport
+without buffering whole audio files.
+
+## Compatibility
+
+Existing CLI commands, speaker identities, transcript formats, and pipeline
+ordering are unchanged. Session manifests gain optional per-speaker completion
+evidence. Older manifests remain readable, but older Narratio binaries may
+reject manifests containing the new fields; downgrading after transcription
+is not transparent.
+
+The optional `pipeline.notarius.config_profile` field selects a downstream
+Notarius configuration profile independently of Narratio's own profile. Using
+it requires a Notarius version supporting `--config-profile`; v0.7.0 is a known
+supporting version. Omitting the field retains downstream default selection.
+
+## Upgrade
+
+No configuration migration is required. When transcribe is next selected for
+an older aggregate-only manifest, all current speakers are transcribed once
+to establish reusable evidence. Previously unrecorded results from failed runs
+are not automatically imported.
+
+Use ordinary run/resume to retain valid checkpoints. Forcing transcribe resets
+reuse of prior results; an ordinary retry after a failed forced invocation can
+retain replacements already checkpointed by that attempt. See the
+[operations guide](../operations.md) and
+[Notarius profile configuration](../config.md#notarius-configuration-profile).
+
+## Changes
+
+- Persist validated speaker completions independently of aggregate stage status,
+  with serialized saves for concurrent work and input/output integrity checks.
+- Rebuild aggregate transcript references when speakers are removed or those
+  references need repair, without retranscribing otherwise-current speakers.
+- Keep removed and incomplete speaker results out of versioned merge inputs.
+- Permit checkpoint evidence for zero-byte audio when WhisperX accepts it;
+  service rejection still fails normally.
+- Provide fresh streaming multipart bodies for HTTP transport replay while
+  preserving application retries, cancellation, and resource cleanup. This
+  addresses the missing-body-replay limitation, not persistent upstream
+  protocol failures or exactly-once service execution.
+- Pass explicit Notarius configuration profiles through the CLI and include
+  their selection in extraction reuse decisions.

+# Adopt Audita v2 and ConfigKit v0.4.0
+
+Status: implemented (2026-09-25); release pending.
+
+## Goal
+
+Migrate Narratio's `polish` integration from Audita's former command/configuration
+contract to Audita v2.0.0. Keep Narratio responsible for orchestration and Audita
+responsible for correction behavior and LLM execution configuration.
+
+Adopt a consistent provider-named credential list for both Audita and Notarius,
+so operators define each secret once and explicitly share it with the downstream
+applications that need it. This is a clean cutover without backward-compatibility
+shims.
+
+Adopt ConfigKit v0.4.0 and use “overlay” consistently for Narratio's selected
+pipeline configuration, distinct from downstream LLM model profiles.
+
+Production runs use Audita's default reporting configuration: Narratio passes
+neither `--debug` nor `--reporting=false`. Normal reports remain available without
+enabling debug diagnostics. Adding debug reporting through Narratio's testing
+profile is deferred.
+
+This document defines the intended end state, migration scope, and policy.
+The [implementation plan](implementation.md) owns implementation sequencing and
+verification steps.
+
+## Baseline and upstream contract
+
+The baseline is Narratio v2.2.1 and the Audita checkout tagged v2.0.0. Upstream
+references are Audita's `docs/migrations/v2.md`, `docs/cli.md`,
+`docs/integrations/subprocess.md`, and `docs/integrations/output-files.md`,
+available in the sibling `../audita/` checkout. Narratio's current contract is
+documented in [Integration: Audita](../integrations/audita.md).
+
+The current integration is not compatible with Audita v2:
+
+- It requests `--report-json` by default; that flag has been removed.
+- It can pass retired endpoint, model, concurrency, and work-directory-retention
+  flags.
+- It expects one JSON report instead of the normal v2 report bundle.
+- Its single forwarded `AUDITA_LLM_API_KEY` has no implicit meaning in v2;
+  an Audita backend must explicitly reference that environment variable.
+- Its semantic fingerprint sorts modules, although Audita treats module order
+  and repetitions as meaningful.
+
+Audita v2 requires a version-2 configuration file. An explicit `--config` selects
+one; otherwise Audita performs its own documented discovery. Backend definitions
+own endpoints, credentials, and capacity. PromptKit profiles own models and
+per-attempt controls. Audita owns retry/repair policy and operation deadlines.
+Narratio's generated invocation YAML is a diagnostic record, not a substitute
+for that Audita configuration file.
+
+## Target architecture
+
+Retain the existing subprocess boundary and `polish` stage. Do not introduce a
+second correction engine, an in-process Audita dependency, or a generic external
+tool configuration framework.
+
+Narratio owns:
+
+- Selection of the executable and the overall invocation timeout/cancellation.
+- Transcript and glossary inputs, run-local output placement, validation of the
+  corrected transcript, and promotion to the existing polished transcript
+  identity.
+- Explicit configuration/profile selections and supported domain overrides.
+- Deliberate credential forwarding, secret-safe invocation diagnostics, and
+  manifest references to results and reports.
+- Existing stage completion, resume, force, publish, restore, and cleanup
+  behavior.
+
+Audita owns its configuration schema and discovery, backend/model configuration,
+provider execution, correction sequence, recovery behavior, and report contents.
+Narratio does not translate old settings into a generated v2 configuration or
+duplicate Audita's complete validation logic.
+
+## Configuration and invocation migration
+
+### ConfigKit and pipeline overlays
+
+Upgrade Narratio's ConfigKit dependency from v0.3.1 to v0.4.0. ConfigKit's
+selected-configuration terminology changes from profile to overlay: the Go API
+uses `Options.Overlay`, `LayerOverlay`, and `CodeOverlay*`; source layers and
+diagnostic codes use `overlay` and `overlay.*`. Composition, precedence, secret
+resolution, and lifecycle semantics otherwise remain unchanged.
+
+Narratio's pipeline-selection interface becomes `--overlay`, selecting
+`overlays/<name>.yml` beside the root pipeline file. Remove `--profile` and old
+selected-directory discovery without aliases or fallbacks. Preserve existing
+base selection for omission, explicit empty selection, and `default`.
+Configuration inspection, diff descriptions, internal selection names, and
+newly written selection provenance use overlay terminology as well.
+
+Maintain existing value-based digest and stage-reuse semantics; renaming
+informational selection provenance is not a reason to invalidate completed
+work or automatically rewrite historical manifests. Strict manifest decoding
+rejects retired provenance fields; operators must deliberately migrate that
+informational member on a backed-up manifest, preserving execution/checkpoint
+state. Update maintained examples and operator migration guidance for the
+directory, flag, and provenance changes.
+
+This rename does not apply to downstream model profiles, Scriptorium
+`profile_id`, Audita's proposal/validation profiles, or Notarius's
+`config_profile`. Nor does it prohibit ordinary explicit imports from a directory
+named `profiles`. Narratio overlays do not automatically select downstream
+overlays or profiles. These are independently owned choices.
+
+### Audita v2 configuration
+
+Keep binary, timeout, explicit config-path selection, and surviving explicit
+domain overrides such as transcript description, output schema, and modules.
+Allow Audita's native configuration discovery when no config path is selected;
+do not impose an additional requirement to supply an explicit path.
+
+Provide optional Audita overlay, proposal-profile, and validation-profile
+selectors, passed through to their corresponding CLI flags. Omission leaves
+Audita's own defaults and validation-profile inheritance in control. These are
+Audita selectors, not automatic translations of Narratio overlay names.
+
+Retire the Narratio settings that mirror removed Audita endpoint/model/capacity
+flags and work-directory retention. Move their operational meaning into the
+operator-maintained Audita configuration and profiles. Remove stale adapter
+fields, validation, invocation metadata, examples, and tests along with them.
+Remove the old report toggle and both adapters' singular `llm_api_key` fields
+from accepted Narratio configuration. Do not retain deprecated aliases,
+automatic conversion, ignored fields, or a v1 execution path. Existing strict
+configuration decoding rejects removed fields. Provide migration guidance and a
+release compatibility notice rather than runtime compatibility machinery.
+
+Preserve the distinction between omitted modules and an explicitly empty module
+list: omission requests Audita's configured/default sequence; an empty list
+requests no correction modules. Preserve order and repetitions rather than
+sorting or deduplicating. Do not broaden this into a change to unrelated
+adapters' module semantics.
+
+Normal invocations no longer pass `--report-json`, `--work-dir-retention`, or
+debug-work-directory flags as a way to obtain reports. They need no reporting
+override: Audita writes its ordinary report bundle by default. The old
+Narratio `report` toggle must not silently become `--reporting=false`.
+
+The production Audita configuration must also retain reporting enabled and debug
+disabled. Omitting CLI flags does not override an operator's explicit external
+configuration. Document this distinction rather than silently adding forced
+boolean overrides or rejecting otherwise valid Audita configuration.
+
+## Credentials
+
+Define secrets once under provider-oriented environment-variable names, such as
+`OPENROUTER_API_KEY` and `RAKESTRAWHOME_API_KEY`, through the process environment
+or Narratio's existing secrets-directory bootstrap. These names are examples,
+not a fixed provider registry; application-specific names are not required.
+
+Add `pipeline.audita.credentials` and `pipeline.notarius.credentials` as lists
+of Narratio typed secret references. Each entry names the environment variable
+whose captured value is forwarded under that exact name. Omission or an empty
+list forwards no credentials. The same reference may appear in both adapters'
+lists without duplicating its stored secret value. An illustrative configuration
+fragment is:
+
+```yaml
+pipeline:
+  audita:
+    credentials:
+      - OPENROUTER_API_KEY
+      - RAKESTRAWHOME_API_KEY
+  notarius:
+    credentials:
+      - OPENROUTER_API_KEY
+```
+
+Resolve references through the existing configuration/secret-loading mechanism
+before adapter execution, preserving its nonempty-value requirement. Forward
+the captured values rather than rereading the parent environment during a run.
+Retain the minimal child execution environment plus each adapter's explicit
+credential list; do not forward every secret found during bootstrap.
+
+Audita backends select these names through `credential`; the current Notarius
+PromptKit profiles select them through `api_key_env`. Narratio neither inspects
+downstream configuration to infer required credentials nor translates names,
+registers providers, or duplicates backend configuration. Audita resolves
+credentials for every surviving configured backend, even one not selected by
+a profile, so its list must cover all those references.
+
+Generalize Notarius's current single-name forwarding and replace Audita's fixed
+`AUDITA_LLM_API_KEY` destination with this shared convention. Use existing shared
+secret and subprocess facilities, extending narrow helpers where needed rather
+than introducing a new secret-management framework. Register every forwarded
+credential with captured-output redaction, including custom names and multiple
+keys. Values must not enter arguments, generated configuration, manifests,
+logs, or examples. As today, downstream tools remain responsible for files they
+write directly; this does not add arbitrary downstream-file scanning.
+
+## Ordinary reports and result handling
+
+Replace the old `audita.report.json` handling with Audita's normal `errors.yml`,
+`recoveries.yml`, and `report.md` bundle. With a file output, Audita writes these
+beside the corrected transcript; an arbitrary report destination is not supplied
+through the removed report flag.
+
+Discover the reports at their defined run-local locations and retain them as
+diagnostics using Narratio's existing manifest and diagnostic lifecycle. Keep
+them distinguishable from the canonical polished transcript. Adapt report
+references, publication/restore coverage, and operator inspection guidance so
+the bundle is not lost or confused with an older run's JSON report. Do not
+fabricate a legacy JSON report or delete historical diagnostics as part of the
+migration.
+
+Retain existing bounded, confined file handling. Replace JSON-specific report
+handling with only the validation needed for consuming the v2 bundle; do not
+introduce a second comprehensive report-schema validator or make incidental
+Markdown wording a contract. Report locations must be discoverable without
+parsing human-readable stderr. Detailed report-counter ingestion is not required
+for this migration.
+
+Audita's exit status remains authoritative. Exit zero with a valid corrected
+transcript may include recoverable LLM failures, including a normalized result
+with no model corrections. Preserve the reports so operators can assess that
+outcome; do not add an unrequested fail-on-recovery or minimum-correction policy.
+
+Conversely, a nonzero exit must fail polish even if a transcript file exists:
+Audita can fail while writing required reports after writing the transcript.
+Preserve available failure diagnostics without requiring early failures to have
+produced a complete report bundle. Failed output must not become the canonical
+successful result.
+
+## Resume and semantic evidence
+
+Update polish's semantic evidence for the new result-affecting selections and
+remove retired endpoint/model fields. Include explicit config/overlay/profile
+selection and preserve ordered module semantics, including omitted versus empty
+selection. Version the changed evidence so incompatible older evidence is not
+mistaken for a valid match when polish is considered for reuse.
+
+Keep the existing boundary for opaque downstream configuration: Narratio does
+not recursively hash Audita configuration, overlays, and profile contents.
+Operators force polish when changing contents behind unchanged selectors.
+Timeouts, credential values, reporting details, and other execution-only settings
+must not become blanket semantic invalidation keys. Do not rerun unrelated or
+unselected stages merely because the integration was upgraded.
+
+## Migration guidance and verification
+
+Update the canonical [configuration reference](../config.md),
+[Audita integration contract](../integrations/audita.md),
+[Notarius integration contract](../integrations/notarius.md),
+[polish internals](../internal/stage-polish.md), maintained examples, and relevant
+operations/troubleshooting guidance when implementation lands. Cover:
+
+- Moving selected Narratio pipeline files to `overlays/`, replacing `--profile`
+  with `--overlay`, and distinguishing configuration overlays from model profiles.
+- Updating ConfigKit API/source attribution and verifying unchanged effective
+  values retain existing semantic reuse behavior.
+- Preparing and validating an Audita v2 configuration and its profiles before
+  switching the executable; copying an old v1 configuration is insufficient.
+- Moving endpoint, model, capacity, and credential selections to their v2 owners.
+- Replacing both singular `llm_api_key` settings with explicit `credentials`
+  lists, storing each provider key once, and matching downstream credential
+  references to those names. State clearly that old fields are removed.
+- Using normal reports to inspect recoveries and failures without debug mode.
+- Force/resume expectations and the treatment of existing completed sessions.
+- The explicitly deferred nature of Narratio testing-profile debug support.
+
+Verification should exercise the real adapter boundary with offline subprocess
+fixtures and focused stage/configuration tests: accepted v2 arguments, omitted
+defaults, ordered/empty modules, secret-safe forwarding, successful report
+capture, recoverable-error success, nonzero exit with an existing transcript,
+failure diagnostics, and semantic reuse/invalidation. Update existing behavioral
+tests rather than retaining assertions for removed flags or exact stderr prose.
+Where practical, verify invocation against the tagged Audita CLI without live
+provider calls. Follow the repository's testing and documentation policies.
+
+Credential tests must cover both adapters, multiple custom names, reuse of one
+secret by both tools, no forwarding of unselected secrets, captured-value
+semantics, and redaction of every forwarded value. Verify removal of obsolete
+configuration fields without preserving their compatibility behavior.
+
+## Scope boundaries
+
+No changes to pipeline order, transcript identity, downstream artifact
+definitions, or provider algorithms are intended. No automatic v1 configuration
+converter, Audita-internal resume mechanism, runtime binary-version negotiation,
+or live-service release gate is required. Debug-profile integration and ingestion
+of Audita's debug-only execution artifacts are future work.
+
+The Notarius change is limited to credential configuration, forwarding, and
+associated diagnostics/documentation/tests; extraction and cache behavior are
+unchanged. This migration breaks existing pipeline configurations using removed
+fields; account for that explicitly in Narratio release versioning.

+# Bugfix Request: Preserve Publish Destination Derivation with Explicit Rules
+
+Status: Implemented; release target v2.1.1
+
+## Summary
+
+Narratio should successfully derive a publish destination when a valid
+`publish.outputs` rule omits `dest`, regardless of whether that rule explicitly
+sets `required`. Narratio v2.1.0 currently rejects this valid configuration in
+some cases with a ConfigKit `resolve.unrecorded_change` diagnostic.
+
+This is a configuration-resolution bookkeeping defect, not a YAML formatting
+restriction. The fix should preserve the existing public configuration
+contract: operators may omit a derivable destination and may independently set
+`required` to either `true` or `false`.
+
+## Observed Behavior
+
+A pipeline containing a rule equivalent to the following fails during native
+configuration loading:
+
+```yaml
+publish:
+  outputs: [{"source": "narratio.transcript.final", "required": true}]
+```
+
+Narratio reports:
+
+```text
+error [resolve.unrecorded_change] /publish/outputs: application resolution changed a value without a covering record
+```
+
+The same failure is possible with ordinary block-style YAML when `required` is
+explicit and `dest` is omitted. Flow-style YAML is valid input and is not the
+cause of the defect.
+
+The existing destination-derivation tests do not expose this case because
+their rules also omit `required`. Narratio then supplies the default value for
+`required` and records a change covering the complete `publish.outputs`
+sequence. That broader record happens to cover the destination mutation as
+well, masking the missing resolution record that occurs when `required` is
+already explicit.
+
+## Expected Contract
+
+The current configuration contract remains unchanged:
+
+- `publish.outputs[].source` is required;
+- `publish.outputs[].dest` may be omitted when Narratio can derive it from the
+  selected built-in or configured artifact source;
+- `publish.outputs[].required` defaults to `true`, but an operator may set it
+  explicitly to either `true` or `false`; and
+- equivalent valid YAML representations have equivalent configuration
+  semantics.
+
+For example, both rules below should load and validate, retain their explicit
+requiredness, and receive the canonical derived destination:
+
+```yaml
+publish:
+  outputs:
+    - source: narratio.transcript.final
+      required: true
+    - source: narratio.transcript.final_markdown
+      required: false
+```
+
+## Root Cause
+
+ConfigKit intentionally treats sequences as atomic when comparing values
+before and after application resolution. Changing a field within one
+`publish.outputs` entry is therefore observed as a change to the
+`/publish/outputs` sequence.
+
+Narratio currently derives each missing destination by recording a
+normalization at the individual `publish.outputs[index].dest` path. That child
+record does not cover the atomic parent-sequence change. A separate
+container-level record is currently created only when Narratio also defaults
+an omitted `required` value, so configurations with explicit `required` values
+lose that incidental coverage.
+
+## Recommended Fix
+
+Make Narratio's publish-output resolution bookkeeping conform to ConfigKit's
+atomic-sequence contract. Whenever resolution derives one or more destinations
+inside `publish.outputs`, the recorded resolution changes must cover the
+`/publish/outputs` container. Destination derivation must not depend on an
+unrelated `required` default being applied in the same list.
+
+The implementation may retain more specific provenance where useful, but it
+must provide valid container-level coverage for the sequence mutation. Do not
+change ConfigKit's sequence comparison semantics merely to accommodate this
+call site.
+
+## Scope
+
+- Correct destination derivation for publish rules that explicitly set
+  `required` and omit a derivable `dest`.
+- Preserve explicit `required: true` and `required: false` values.
+- Preserve canonical destination derivation for built-in transcript sources
+  and configured artifact sources.
+- Add focused regression coverage through Narratio's real configuration load
+  and validation boundary.
+- Prepare a backward-compatible patch release after the fix passes the normal
+  repository validation.
+
+## Non-goals
+
+- Changing the `publish.outputs` schema, defaults, source vocabulary, or
+  destination derivation rules.
+- Requiring operators or configuration generators to supply `dest` when it is
+  derivable.
+- Requiring operators to omit explicit `required: true` values.
+- Treating flow-style YAML or JSON-compatible YAML values as unsupported.
+- Changing ConfigKit's documented atomic treatment of sequences.
+- Adding storage, publication, or network integration behavior.
+
+## Regression Coverage
+
+Add one focused package-level behavioral test that loads and validates a
+pipeline with omitted destinations and explicit requiredness. A representative
+list should include both `required: true` and `required: false`, then assert
+that:
+
+- loading and validation succeed;
+- each destination is derived from its source; and
+- each explicit `required` value is preserved.
+
+Using the compact flow-style representation that exposed the integration
+failure is reasonable, while the existing block-style cases continue to cover
+omitted `required`. The test should exercise the public configuration behavior,
+not ConfigKit call choreography or Narratio's private recording mechanism.
+
+No network service, object store, credential, or test double is required.
+
+## Target End State
+
+All valid publish rules with derivable sources behave consistently across
+these cases:
+
+| `dest` | `required` | Result |
+| --- | --- | --- |
+| omitted | omitted | destination derived; required defaults to `true` |
+| omitted | `true` | destination derived; explicit `true` retained |
+| omitted | `false` | destination derived; explicit `false` retained |
+| explicit | either value | explicit destination and requiredness retained |
+
+`narratio config validate`, `narratio config show`, and ordinary pipeline
+loading accept the corrected cases without an unrecorded-change diagnostic.
+No operator configuration migration or workaround is required.
+
+## Release
+
+This is a backward-compatible correction to documented configuration behavior
+and should be released as Narratio `v2.1.1`. The release note should identify
+the corrected explicit-required/derived-destination interaction and state that
+no special upgrade action is required.
+
+## Acceptance Criteria
+
+- The focused regression test fails against v2.1.0 behavior and passes after
+  the fix.
+- Publish rules with explicit `required: true` or `required: false` and omitted
+  derivable destinations load and validate successfully.
+- Derived destinations and explicit requiredness appear correctly in the safe
+  effective configuration.
+- Existing destination derivation, publish validation, imports, profiles, and
+  configuration inspection tests remain green.
+- The complete repository validation and release-candidate checks pass.
+- The correction is published as the immutable `v2.1.1` tag with the required
+  release note.

+# Implementation Plan: Audita v2 and Shared Provider Credentials
+
+Status: Complete (2026-09-25).
+
+## Scope and working instructions
+
+Implement [the Audita roadmap](audita.md). The baseline is Narratio commit
+`70f1dbf` (v2.2.1), with ConfigKit v0.4.0 and Audita v2.0.0 as the target
+upstream contracts. This replaces the completed checkpoint-refactoring plan,
+which remains in Git history.
+
+Complete Stage 1 through Stage 8 in order, one bounded implementation prompt per
+stage for gpt-5.6-terra. Record completion and actual verification results under
+each stage. These instructions apply to the implementation sprint; the planning
+pass changes documentation only. Intermediate stages are not release candidates.
+Do not add compatibility code to make intermediate states look like a supported
+release.
+
+Before each stage, read `AGENTS.md`, `docs/development.md`, and all policies
+under `docs/policy/`: agents, architecture, documentation, testing, and release.
+Read this plan's selected design and that stage's preparation. Use Go 1.26 and graph-first code
+discovery; inspect current files when graph results are incomplete. Preserve
+unrelated changes. Test at behavioral owners rather than replicating every case
+across configuration, adapter, stage, and command tests.
+
+The user approved a clean cutover: no Audita v1 runner, deprecated aliases,
+compatibility shims, generated configuration conversion, or silently ignored
+old settings. Do not broaden that decision into a purge of unrelated legacy
+code or historical session data.
+
+## Selected design
+
+### ConfigKit and Narratio overlay terminology
+
+Upgrade ConfigKit from v0.3.1 to v0.4.0 before adapter work. Rename its
+`Options.Profile`, `LayerProfile`, and any `CodeProfile*` uses to their overlay
+equivalents. Selected pipeline files move from `profiles/<name>.yml` to
+`overlays/<name>.yml`; no fallback directory or alias is permitted.
+
+Rename Narratio's pipeline-selection flag to `--overlay` everywhere it is
+accepted, including convenience commands and configuration inspection. Rename
+application-owned selection types/helpers, help, errors, and current inspection
+labels consistently. `config diff` still takes two positional selections,
+now described as overlays. Preserve omission, explicit empty, and `default`
+as base selection; do not add a persistent default selector or new precedence.
+
+Rename newly written informational provenance to overlay terminology, including
+`selected_overlay` in manifest configuration provenance. Do not add a dual-field
+reader, automatically rewrite historical manifests, or introduce a manifest-version
+rejection solely for this informational rename. Existing strict typed decoding
+rejects retired provenance fields. Document backed-up operator migration of
+that informational member without changing execution/checkpoint state; it does
+not become resume authority. Preserve
+semantic fingerprints and effective-value digest rules when values are unchanged.
+
+Only Narratio pipeline configuration selection is renamed. Keep model/profile
+fields such as Scriptorium `profile_id`, Audita `proposal_profile` and
+`validation_profile`, and Notarius `config_profile` unchanged. Explicit imports
+from directories named `profiles` remain legal; only selected pipeline overlay
+discovery changes. Do not globally replace the word “profile.”
+
+### Configuration and credentials
+
+- Both `pipeline.audita.credentials` and `pipeline.notarius.credentials` are
+  lists of ConfigKit secret references. Use `[]configkit.Secret`; each element
+  is an actual reference rather than a nullable pointer. Existing ConfigKit
+  validation owns name/value resolution. Omitted, null, or empty lists mean no
+  additional credential forwarding.
+- Define each key once through existing environment/secrets-directory bootstrap.
+  Forward it under its original name to each adapter whose list includes it.
+  No alias mappings, provider registry, downstream config inspection, extra
+  bootstrap, or inheritance of the entire environment.
+- Repeated names need no new rejection rule: forwarding the same captured
+  reference once suffices. Arbitrary valid variable names remain supported;
+  provider names in the roadmap are examples, not an allowlist.
+- Add a narrow shared helper in `internal/adapters/subprocess` converting resolved
+  references to `EnvOverrides` and `SensitiveEnvNames`. It checks the existing
+  resolved/nonempty requirement for direct adapter callers but never resolves
+  secrets or rereads environment values. Errors expose no values. Both adapters
+  use it; the ConfigKit upgrade is owned by Stage 1, not this helper. No new
+  credential service is needed.
+- Configuration projections and diagnostic metadata contain reference names
+  only. Register all forwarded names for existing captured-stream redaction.
+  Downstream tools remain responsible for files they write themselves.
+- Remove both singular `llm_api_key` fields. For Audita also remove `base_url`,
+  `model`, `validation_model`, `total_llm_concurrency`,
+  `proposal_llm_concurrency`, `validation_llm_concurrency`,
+  `work_dir_retention`, and `report`, including defaults and projections.
+- Retain Audita `binary`, `timeout`, `config_path`, `transcript_description`,
+  `output_schema`, and `modules`. Add optional string selectors `overlay`,
+  `proposal_profile`, and `validation_profile`: empty/unset means no CLI
+  override. Audita owns downstream file/profile validation and native config
+  discovery. Narratio overlay names are not implicitly Audita overlay names.
+- Preserve nil versus non-nil empty `modules` through loading, projection,
+  cloning, composition, adapter defaults, and request overrides. Nil omits the
+  flag; empty passes `--modules` with an empty argument; nonempty joins in order
+  with repetitions intact. A nil request override uses the configured selection.
+  Avoid clones that collapse empty slices to nil. YAML null follows unset
+  behavior. Other adapters' module semantics do not change.
+
+### Invocation, reports, and failure
+
+Use `process INPUT --glossary PATH --output PATH` plus selected surviving
+overrides. Production passes no reporting or debug switches, including
+`--debug`, `--reporting=false`, `--report-dir`, or `--work-dir`.
+Remove required `WorkDir` and legacy `ReportPath` request/result plumbing.
+Document production external-config defaults without forcibly overriding or
+rejecting deliberate external reporting/debug choices.
+
+Replace Audita's long positional config-values constructor with typed runner
+configuration. Keep timeout parsing in composition and subprocess cancellation
+through the existing runner. No version probe or automatic config-validation
+subprocess is required.
+
+The corrected transcript remains the only canonical polish output, with existing
+identity, path, validation, and bounded file handling. Discover exactly
+`errors.yml`, `recoveries.yml`, and `report.md` beside the requested output.
+Represent available paths in a small typed report bundle in `PolishResult`.
+Fixed names belong to the adapter; do not parse stderr or recursively scan.
+
+Reports are diagnostics, not a new correctness gate:
+
+- Bound reads of present reports using the existing named 16 MiB report limit;
+  retain confined regular-file handling and errors identifying Audita, the file,
+  and limit. No new smaller limits or report schema/status/count validation is
+  necessary when Narratio only preserves bytes; Markdown needs no parser.
+- Missing files are not independently fatal: external configuration can disable
+  reports and early failures may produce none. Default-reporting success tests
+  must nevertheless demonstrate capture of all three files.
+- On process failure, preserve available diagnostics and the original error;
+  report-inspection errors must not hide it. Never promote an output merely
+  because it exists following a nonzero exit.
+- Exit zero with a valid transcript may include recoverable errors or no model
+  corrections. Accept it without a fail-on-recovery or minimum-correction rule.
+
+Keep reports next to the run-local transcript, not in a second canonical
+destination. Register present report paths in the existing `StageResult.Logs`
+diagnostic collection alongside stdout/stderr, with safe bundle-path metadata.
+Reuse current manifest-driven diagnostic publication rather than adding a
+manifest schema or new publish source IDs. Physical placement does not define
+canonical artifact identity. Existing diagnostic retention/cleanup rules apply.
+
+On failure, retain run-local files and expose the output/report directory in
+contextual errors. Do not add runner-wide failed-result persistence merely to
+register those files. Do not fabricate legacy JSON reports or delete historical
+reports. Normal successful stage-record replacement removes obsolete current
+output references.
+
+Generated invocation YAML becomes `audita.generated.v2`, recording actual
+arguments, selections, paths, and credential names, never values. This remains
+a diagnostic invocation record, not an Audita configuration file.
+
+### Resume boundary
+
+Bump only polish semantic-config version from 1 to 2. Record config path,
+overlay/proposal/validation selectors, ordered modules with presence preserved,
+transcript description, output schema, and existing output identity. Remove old
+endpoint/model fields. Existing runner comparison reconsiders obsolete evidence
+when polish is selected; do not synthesize equivalent fingerprints or expand
+normal dependency/selection invalidation.
+
+Credentials, binary path, timeout, and diagnostics are not semantic keys. Do not
+hash downstream config/profile contents; operators force polish after edits
+behind unchanged selections. Notarius credential migration does not change
+extraction fingerprints, references, force, resume, or chunk-cache behavior.
+
+## Stage 1: Adopt ConfigKit v0.4.0 and pipeline overlays
+
+Status: Complete (2026-09-25).
+
+Verification: `go test ./internal/config ./internal/app ./internal/manifest`,
+`go test ./...`, `go test ./internal/doccheck`,
+`go test ./internal/config -run '^TestExamplesLoadAndValidate$'`, and
+`git diff --check` passed.
+
+Preparation: ConfigKit v0.4.0 release notes and selected-overlay migration guide
+in `../ConfigKit/docs/`; Narratio `internal/config/pipeline_configkit.go`,
+`artifact_catalog.go`, `load.go`, `effective_digest.go`; CLI flag parsing and
+config commands in `internal/app/`; configuration provenance in
+`internal/manifest/manifest.go`; current config/CLI docs and pipeline examples.
+
+1. Update `go.mod`/`go.sum` to ConfigKit v0.4.0 using normal module tooling;
+   do not leave a local replacement or change unrelated dependencies.
+   Replace removed ConfigKit APIs in loading, ownership, and artifact catalog
+   inspection. Account for source layer `overlay` and diagnostic prefix
+   `overlay.*` wherever they are consumed or asserted.
+2. Rename Narratio's pipeline selector to `--overlay` across all commands and
+   aliases, load options, pair loading, inspection, provenance, and tests.
+   Preserve explicit-presence handling through convenience commands and existing
+   base/default selection. Remove `--profile` rather than retaining an alias.
+   Apply the selected design's informational manifest-provenance treatment.
+3. Move maintained selected pipeline files and generated fixture paths to
+   `overlays/`. Update current canonical documentation, policy terminology,
+   examples, and user-visible migration guidance with the directory/flag break.
+   Do not rewrite historical release notes, rename downstream model profiles,
+   or prohibit ordinary explicit imports from a directory named `profiles`.
+4. Adapt existing config/app tests to prove base and named-overlay selection,
+   imported defaults plus overrides, secret replacement/removal, source attribution
+   through character-family expansion, config diff, and convenient-command
+   forwarding. Add focused checks that the retired flag is rejected and the old
+   directory is not a discovery fallback. Do not freeze incidental error wording.
+5. Verify unchanged effective values retain digest and stage-reuse behavior;
+   only diagnostic source labels/paths and selected provenance terminology change.
+   Test current provenance round trips and strict rejection of unknown/retired
+   provenance fields. Document deliberate operator migration; do not add a
+   compatibility decoder, semantic invalidation rule, or schema-version gate.
+6. Run focused and full tests before proceeding so failures from the dependency
+   and terminology change are separated from adapter migrations. No Audita or
+   Notarius credential/CLI behavior changes in this stage.
+
+Verify: `go test ./internal/config ./internal/app ./internal/manifest`,
+`go test ./...`, `go test ./internal/doccheck`,
+`go test ./internal/config -run '^TestExamplesLoadAndValidate$'`, and
+`git diff --check`.
+
+Done when Narratio uses ConfigKit v0.4.0, exposes pipeline overlays consistently,
+has no old selector/directory fallback, and preserves configuration semantics and
+downstream model-profile concepts.
+
+## Stage 2: Add shared resolved-credential forwarding
+
+Status: Complete (2026-09-25).
+
+Verification: `go test ./internal/adapters/subprocess`,
+`go test -race ./internal/adapters/subprocess`, and `git diff --check` passed.
+
+Preparation: `internal/adapters/subprocess/run.go`, its environment/redaction
+helpers and tests; `internal/adapters/notarius/subprocess.go`;
+`internal/config/credential_projection.go`; the pinned ConfigKit secret API.
+
+1. Add the narrow helper described above. Return an independent environment map
+   and selected sensitive names. No logging/serialization of values and no
+   changes to minimal child environment inheritance.
+2. Test multiple custom names, empty lists, repeated names, unresolved references,
+   and captured values after the parent environment changes. Reuse existing
+   split/overlapping-stream redaction coverage rather than repeating its matrix.
+3. Leave production callers unchanged until their migrations.
+
+Verify: `go test ./internal/adapters/subprocess` and
+`go test -race ./internal/adapters/subprocess`.
+
+Done when both adapters can reuse one small conversion mechanism without adding
+a resolver, provider policy, or ambient-secret inheritance.
+
+## Stage 3: Migrate Notarius to credential lists
+
+Status: Complete (2026-09-25).
+
+Verification: `go test ./internal/config ./internal/adapters/notarius ./internal/stage ./internal/app`,
+`go test -race ./internal/adapters/notarius`, and `git diff --check` passed.
+
+Preparation: `internal/config/config.go`, `credential_projection.go`, loading/
+inspection tests; `internal/adapters/notarius/runner.go`, `subprocess.go`;
+`internal/stage/extract.go` and its request construction;
+`docs/integrations/notarius.md` and secret handling in `docs/config.md`.
+
+1. Replace the singular field with the typed list across configuration,
+   projection, request types, stage wiring, and adapter execution. Use Stage 2's
+   helper and register all selected names for redaction.
+2. Update name-only metadata and config-show/diff/effective projections. Test
+   real ConfigKit loading, overlay list replacement, and empty-list clearing.
+   Preserve bootstrap precedence and existing load-time reference resolution,
+   including references outside the selected stage range.
+3. Migrate maintained examples, fixtures, and current Notarius configuration/
+   integration documentation for this field. Ordinary strict decoding rejects
+   the old field; do not add a compatibility parser.
+4. Cover multi-key forwarding, unselected-key exclusion, empty selection,
+   captured-value behavior, and custom-name redaction on success/failure.
+   Keep extraction cache/reference/output tests as regression protection,
+   not occasions to redesign extraction.
+
+Verify: `go test ./internal/config ./internal/adapters/notarius ./internal/stage ./internal/app`
+and `go test -race ./internal/adapters/notarius`.
+
+Done when Notarius uses credential lists end to end and no active singular
+credential path remains.
+
+## Stage 4: Cut Audita configuration and adapter over to v2
+
+Status: Complete (2026-09-25).
+
+Verification: `go test ./internal/config ./internal/adapters/audita ./internal/stage ./internal/app`,
+`go test -race ./internal/adapters/audita`, `go test ./...`, and
+`git diff --check` passed.
+
+Preparation: Audita v2.0.0 `docs/migrations/v2.md`, `docs/cli.md`,
+`docs/integrations/subprocess.md`, and `docs/integrations/output-files.md` in
+`../audita/`; Narratio `internal/adapters/audita/`,
+`internal/app/runner.go` (`buildDefaultAuditaRunner`), and config types,
+defaults, validation, and credential projection.
+
+1. Replace the Audita configuration surface as selected above, updating defaults,
+   validation, safe projection, examples, and config fixtures. Prove nil/empty
+   modules survive real configuration loading and overlay overrides.
+2. Migrate runner construction, selectors, and credential forwarding. Remove
+   retired flags, fixed credential alias, required work-directory plumbing, and
+   old JSON-report validation. Add the typed report bundle.
+3. Implement adjacent report discovery, bounded reads, failure results, and
+   generated invocation v2. Share metadata construction between success/failure
+   instead of maintaining duplicate field maps.
+4. Rewrite the Audita subprocess fixture to model v2 argument acceptance and
+   output placement. Cover omitted/selected selectors, ordered/repeated/empty
+   modules, no report/debug switches, malformed/missing transcript, ordinary
+   reports, externally disabled reporting, recoverable-error success, and
+   nonzero exit after transcript creation. Cover multiple custom credential names
+   and redaction; preserve timeout/cancellation coverage at its existing owner.
+5. Make mechanical polish and app-fixture adjustments needed to compile: remove
+   obsolete request/metadata fields and old report materialization. Stage 5 owns
+   complete diagnostic integration. Remove retired fingerprint members as needed
+   to compile; Stage 6 completes the replacement semantic contract. These are
+   bounded call-site changes, not permission to introduce transitional shims.
+
+Verify: `go test ./internal/config ./internal/adapters/audita ./internal/stage ./internal/app`
+and `go test -race ./internal/adapters/audita`.
+
+Done when configuration composes a v2-only adapter and subprocess tests prove its
+credential/transcript/report boundary. Stages 5 and 6 complete diagnostic and
+semantic integration; all stages are required before release.
+
+## Stage 5: Integrate polish reports with diagnostic lifecycle
+
+Status: Complete (2026-09-25).
+
+Verification: `go test ./internal/stage ./internal/app ./internal/manifest ./internal/artifacts`,
+`go test -race ./internal/stage ./internal/app`, and `git diff --check` passed.
+
+Preparation: `internal/stage/polish.go`, `polish_test.go`, `run_local.go`,
+`stage.go`, `publish_sources.go`; result application in `internal/app/runner.go`;
+publish/restore diagnostic tests; `docs/internal/stage-polish.md`.
+
+1. Finish stage integration: materialize only the canonical polished transcript;
+   register available adjacent reports as diagnostics plus safe metadata and
+   existing logs/generated invocation references. Remove old `audita_report`
+   production and stale stage metadata.
+2. Use existing authoritative-path checks for the requested transcript and fixed
+   adjacent report paths. Do not accept arbitrary fake-returned paths, scan
+   directories, or copy reports to a second destination. Preserve workspace
+   handling/modes.
+3. On execution failure, preserve canonical transcript authority and run-local
+   diagnostics, with actionable directory/log context and original error identity.
+   Test failure after output creation.
+4. Adapt the fake and app helper. With real manifest/store collaborators, prove
+   successful promotion, report references, absence of report canonical outputs,
+   and current-run diagnostic publication. Preserve restore's existing scope of
+   declared committed transcript/artifact objects: run-archive diagnostics do not
+   become automatically restored canonical objects. Test that report references
+   do not create new required canonical restore targets. Document remote diagnostic
+   inspection separately; no new diagnostic-restore feature is authorized.
+5. Leave historical files untouched. Update tests expecting a second canonical
+   polish output without introducing a manifest-format migration.
+
+Verify: `go test ./internal/stage ./internal/app ./internal/manifest ./internal/artifacts`
+and `go test -race ./internal/stage ./internal/app`.
+
+Done when reports use existing diagnostic lifecycle and failed execution cannot
+promote an incidental transcript.
+
+## Stage 6: Complete semantic evidence and resume behavior
+
+Status: Complete (2026-09-25).
+
+Verification: `go test ./internal/stage ./internal/app`,
+`go test -race ./internal/stage ./internal/app`, and `git diff --check` passed.
+
+Preparation: `internal/stage/semantic_contracts_refinement.go`, semantic
+fingerprint tests, app runner semantic comparison tests, and extraction semantic
+configuration tests (locate their current owners through graph discovery).
+
+1. Implement polish evidence version 2 and the selected payload. Remove sorting;
+   preserve nil/empty distinction in payload encoding and copies.
+2. Test changes from module order/repetition/presence and external selectors.
+   Credentials and execution-only settings do not change evidence. Avoid
+   assertions on incidental digest literals.
+3. Exercise old-version evidence through runner resume behavior: selected polish
+   is reconsidered and normal dependent invalidation applies. Downstream-only
+   bounded execution does not unexpectedly invoke polish. Unchanged new evidence
+   reuses valid completed output.
+4. Confirm credential-list changes leave extraction semantic/cache behavior
+   unchanged. No downstream file-content scanning or eager fingerprint migration.
+
+Verify: `go test ./internal/stage ./internal/app` and
+`go test -race ./internal/stage ./internal/app`.
+
+Done when selections affect reuse accurately without blanket credential/config
+invalidation or changes to unselected-stage execution.
+
+## Stage 7: Complete operator migration documentation and examples
+
+Status: Complete (2026-09-25).
+
+Verification: `go test ./internal/doccheck`,
+`go test ./internal/config -run '^TestExamplesLoadAndValidate$'`, and
+`git diff --check` passed.
+
+Preparation: documentation policy; `docs/config.md`, `docs/operations.md`,
+`docs/troubleshooting.md`, both integration guides,
+`docs/internal/adapters.md`, `docs/internal/stage-polish.md`, and pipeline examples.
+
+1. Complete current-behavior documentation as implementation lands. Configuration
+   owns fields/defaults; integrations own external contracts; operations owns
+   placement and migration; internal docs explain ownership and link onward.
+2. Provide an old-to-new migration table: endpoints/capacity move to Audita
+   backends, models to profiles, role selection to selectors, and credentials to
+   provider-named lists. Remove report/retention settings. Explain Audita's
+   all-configured-backend credential resolution and Notarius's profile lookup.
+3. Describe preparing and validating Audita v2 config offline with its documented
+   command before switching executables. Link upstream examples rather than
+   building a downstream configuration generator. Explain ordinary reports,
+   recoverable-error success, and force after edits behind unchanged selectors.
+4. Production examples omit modules when upstream defaults are intended;
+   `modules: []` deliberately disables correction modules. Production external
+   Audita config keeps reports enabled/debug disabled, without Narratio flag
+   overrides. Testing-profile debug integration remains deferred.
+5. Document the configuration-breaking clean cutover for release-version
+   consideration. Do not edit historical release records, tag a release, or
+   remove unrelated roadmaps.
+
+Verify: `go test ./internal/doccheck`,
+`go test ./internal/config -run '^TestExamplesLoadAndValidate$'`, and
+`git diff --check`.
+
+Done when operators can migrate using valid examples without obsolete fields,
+implicit credential aliases, or retired CLI/report expectations.
+
+## Stage 8: Verify assembled behavior and audit scope
+
+Status: Complete (2026-09-25).
+
+Verification: the offline app-level shared/Audita-only credential scenario
+passed with config bootstrap, both subprocess fixtures, safe inspection/logging,
+and ordinary polish reports. The tagged Audita v2.0.0 CLI validated its minimal
+configuration and produced a transcript plus all three reports with an empty
+module sequence and no provider request. Active-reference and scope audits found
+no removed production fields or compatibility path; remaining old names occur in
+migration guidance, explicit-rejection checks, or historical fixtures. `go test
+./...`, `go test -race ./...`, `go vet ./...`, `go build ./...`, `go test
+./internal/doccheck`, `go test ./internal/config -run
+'^TestExamplesLoadAndValidate$'`, and `git diff --check` passed.
+
+Preparation: cumulative diff, this plan, feature roadmap, app configuration/
+subprocess integration tests, and all policies.
+
+1. Adapt or add one representative offline app-level scenario showing one
+   provider-named secret source supplying both adapters and another key selected
+   only for Audita. Use real config/bootstrap/composition with subprocess fixtures.
+   Prove safe inspection/logging and successful polish reports. Leave exhaustive
+   flag/redaction cases at lower layers.
+2. Where the tagged Audita checkout is available, smoke-test CLI acceptance and
+   ordinary transcript/reports offline with an explicit minimal v2 config,
+   unauthenticated backend/profile fixtures, and an empty module sequence.
+   No provider requests or production credentials. This is optional local evidence,
+   not a default test dependent on sibling checkouts or installed tools.
+3. Audit active references to removed fields/flags/aliases; historical release
+   notes and completed roadmaps are not compatibility code. Review tests
+   collectively for duplication while retaining consequential failure coverage.
+4. Confirm no provider-name restrictions, duplicate-name rejection, downstream
+   content hashing, fail-on-recovery rule, mandatory explicit config path, debug
+   requirement, live-service gate, pipeline-order change, or Notarius cache change
+   slipped in. Do not require missing reports when disabled externally. Surface
+   additional policy choices rather than encoding them silently in tests.
+5. Run every gate below and record actual results. Mark complete only after all
+   stages and gates pass. No release, tag, push, or unrelated cleanup in this plan.
+
+```sh
+go test ./...
+go test -race ./...
+go vet ./...
+go build ./...
+go test ./internal/doccheck
+go test ./internal/config -run '^TestExamplesLoadAndValidate$'
+git diff --check
+```
+
+Done when the assembled v2 integration and shared credentials meet the roadmap,
+verification passes, and no compatibility machinery remains within scope.
+
+## Open Questions
+
+None requiring a product decision before implementation. The user settled the
+clean cutover and shared provider-named lists. Reports use existing diagnostics
+without new content-based success criteria; debug-profile work remains deferred.
+Release version selection belongs to the later release procedure.

+# Notarius Configuration Profile Selection
+
+Status: Implemented.
+
+## Goal and Authority
+
+Implement the consumer behavior in the
+[feature request](feature-request-notarius-config-profile.yml): let a Narratio
+configuration overlay explicitly select a Notarius configuration overlay.
+Operators can select testing once in Narratio while each application retains
+ownership of its own model choices and other settings.
+
+This roadmap describes the target state and required change areas, not an
+implementation sequence; the [implementation plan](implementation.md) owns
+the ordered work and implementation decisions. The feature request is the scope
+authority; the mechanisms suggested below do not establish additional
+user-facing contracts.
+
+## Underlying Issue
+
+Narratio can select its own testing profile, but extraction currently invokes
+Notarius without a configuration-profile selector. Consequently, a Narratio
+testing invocation cannot explicitly select the independently deployed Notarius
+testing overlay through pipeline configuration.
+
+Adding individual downstream model or tuning fields would duplicate Notarius's
+configuration responsibilities. Passing its existing profile selector provides
+the requested flexibility without that duplication.
+
+## Targeted End State
+
+### Explicit Configuration Composition
+
+`pipeline.notarius.config_profile` is an optional Notarius configuration-profile
+name, usable in Narratio's base configuration and ordinary overlays. For
+example, Narratio's `profiles/testing.yml` may contain:
+
+```yaml
+notarius:
+  config_profile: testing
+```
+
+Selecting Narratio's `--profile testing` then selects that explicit downstream
+profile whenever extraction executes. The two profile names need not match.
+Narratio does not automatically forward its own profile name.
+
+When supplied, the selection is passed through Notarius's `--config-profile`
+argument. Omitted or null values add no profile-selection flag and preserve
+existing downstream selection behavior. Notarius's selector semantics remain
+authoritative, including empty and `default` selections for the composed base
+configuration. Narratio does not introduce a stricter profile-name policy.
+
+This field selects a ConfigKit configuration overlay, not a PromptKit profile
+through `--llm-profile`. The Notarius overlay owns any resulting LLM-profile
+selection. Notarius resolves overlays relative to its own configuration root;
+Narratio neither resolves those files against its own root nor rewrites them.
+
+### Execution, Reuse, and Failure
+
+A changed downstream profile selection must not silently reuse Narratio's
+completed extraction from the previous selection. Existing dependent-stage
+invalidation applies when extraction changes; the feature does not change the
+pipeline order or transcript-generation behavior.
+
+Notarius continues to own downstream overlay discovery, composition, validation,
+and cache compatibility. A missing or invalid selected overlay must fail
+extraction through the existing subprocess error path, without silently falling
+back to production or reporting successful extraction.
+
+Existing resume and chunk-cache controls, including force precedence, remain
+in place. Profile selection does not itself mean forced regeneration or cache
+deletion. Narratio's decision to execute extraction and Notarius's decision to
+reuse compatible work remain separate responsibilities.
+
+Changes to private Notarius configuration behind an unchanged selector retain
+the existing operator responsibility to force extraction when needed. There is
+no new downstream file inspection or content-tracking requirement.
+
+Credential forwarding remains independently configured through
+`notarius.llm_api_key`. A Narratio testing overlay may select a different
+credential reference alongside the downstream profile; no new credential
+discovery or provider-name mapping is introduced.
+
+## Required Change Areas
+
+### Configuration and Inspection
+
+Extend the typed Notarius configuration and its existing safe effective-YAML
+projection to carry the optional field. Preserve the ordinary configuration
+composition behavior for base values, overlay overrides, and null values.
+Configuration inspection must reflect the selected field without exposing
+credential values. No replacement configuration loader or downstream preflight
+loader is needed.
+
+### Stage and Adapter Boundary
+
+Carry the selection from resolved configuration through the extraction request
+to the subprocess adapter. Construct the optional CLI flag using the existing
+argument-vector mechanism, alongside the current configuration path, references,
+credential forwarding, and cache controls. Retain normal Notarius error handling.
+
+### Extraction Reuse Evidence
+
+Account for the downstream selection in the existing extraction reuse evidence.
+The current semantic-configuration and invocation fingerprints are the relevant
+change points. Keep their treatment of selection consistent so that a profile
+change cannot bypass the required rerun and downstream invalidation.
+
+This roadmap does not require a new manifest schema, separate profile-indexed
+workspaces, historical per-profile result retention, or an upgrade-wide forced
+rerun.
+
+### Verification and Documentation
+
+Use focused behavioral coverage for configuration composition and inspection,
+explicit argument forwarding and omission, changed-selection reuse decisions,
+and ordinary subprocess failure handling. Reuse existing test coverage where
+it already protects unchanged credentials, force behavior, and invalidation;
+do not duplicate Notarius's complete profile-validation or cache test suites.
+
+When implemented, update the canonical
+[configuration reference](../config.md),
+[Notarius integration contract](../integrations/notarius.md),
+[extract internals](../internal/stage-extract.md), and relevant maintained
+examples. The development workflow in [Operations](../operations.md) should
+explain explicit profile composition and the existing need to force extraction
+after private downstream edits. Clarify that profile selection does not create
+an isolated testing workspace or separate current extraction state.
+
+## Compatibility and Scope Boundaries
+
+Notarius v0.7.0 already documents `--config-profile`; no upstream change is
+required. Document the capability needed when the option is used, without adding
+an unconditional runtime version gate for existing unconfigured deployments.
+
+This feature adds no Narratio CLI selector, automatic profile propagation,
+Notarius LLM-profile selector, downstream configuration rewriting, new
+credential mechanism, or generalized recursive orchestration. Existing output
+and receipt contracts remain unchanged.
+
+The consumer's Ansible role and suite updates are follow-up work outside this
+repository. They can deploy downstream overlays and populate this field after
+the interface is released.
+
+## Scope Review
+
+No stronger requirements or new invariants are proposed beyond the feature
+request and existing repository contracts. In particular, minimizing one-time
+upgrade invalidation and avoiding reruns between equivalent base selectors are
+implementation considerations, not additional acceptance guarantees imposed
+by this roadmap. No user decisions are currently required before planning.

+# Audita v2 and ConfigKit Migration Review Remediation
+
+Status: Complete.
+
+Reviewed `83eaa96` through `fae18bf` against the approved clean-cutover decisions,
+[feature roadmap](audita.md), and [implementation plan](implementation.md).
+Review date: 2026-09-25. No production changes were made. The previous completed
+transcription review is retained below as historical context.
+
+## 1. Preserve omitted modules in direct YAML serialization
+
+Priority: P2. Status: Complete.
+
+The safe YAML projection now omits nil modules while retaining explicit empty
+and ordered/repeated selections. A round-trip regression failed before the fix
+and passes afterward. Config package tests, including credential-safety coverage,
+and its race tests pass.
+
+Location: `internal/config/credential_projection.go:25` (`AuditaConfig.MarshalYAML`),
+especially the plain slice field at line 30 and assignment at line 40.
+
+The direct safe YAML projection passes a nil module slice to yaml.v3, which
+serializes it as `modules: []`. Loading that output produces a non-nil empty
+slice. Under the new Audita contract these are different instructions: nil
+delegates to Audita's configuration/default sequence; empty passes an explicit
+empty module argument and disables correction modules. Serialization therefore
+silently changes behavior for a configuration that is subsequently reloaded.
+
+Evidence: a temporary package test marshaled
+`AuditaConfig{Binary: "audita", Timeout: "3h"}`, unmarshaled it into another
+`AuditaConfig`, and required `Modules == nil`. It failed with output containing
+`modules: []`. The test was removed after reproduction. This concerns direct
+`yaml.Marshal` of the typed configuration; ordinary CLI `config show` uses
+`MarshalEffectivePipeline` through a separate JSON/value-tree projection and
+does not use this faulty path.
+
+Required remediation:
+
+- Make the direct safe YAML projection preserve nil as null or omission and
+  explicit empty as `[]`. Do not simply add `omitempty` to the slice: that would
+  instead erase the explicit empty selection.
+- Keep credential serialization name-only and preserve module order/repetitions.
+- Add a small round-trip regression covering nil, explicit empty, and an ordered
+  repeated selection; retain effective-output inspection coverage without
+  duplicating its whole test matrix.
+
+## 2. Remove the unapproved manifest compatibility decoder
+
+Priority: P2. Status: Complete.
+
+Removed the permissive custom decoder; ordinary strict typed decoding now
+applies to provenance as well. Replaced historical-acceptance coverage with
+retired/unknown-field rejection tests, all of which failed before removal.
+Current provenance round-trip coverage remains intact. Corrected the roadmap,
+plan, internal contract, and operator guidance for narrow backed-up migration
+without discarding execution/checkpoint state or changing resume authority.
+
+Location: `internal/manifest/manifest.go:79-89`,
+`internal/manifest/store_test.go:78`, and `docs/internal/manifest.md`'s decoding
+contract. Also correct the conflicting migration language in the plan/roadmap.
+
+The new `EffectiveConfigProvenance.UnmarshalJSON` bypasses the manifest store's
+`DisallowUnknownFields` by using permissive `json.Unmarshal` for the entire
+provenance object. It accepts retired `selected_profile` data and silently
+discards it. It also silently accepts unknown current provenance fields,
+including unknown nested selection fields, rather than limiting behavior to
+the renamed label.
+
+The user expressly selected a clean cutover without backward-compatibility
+shims. This adds precisely such a shim and a new historical-input acceptance
+guarantee. The regression test explicitly requires the old selection to load,
+and the internal guide now declares permissive informational-field decoding.
+
+The plan contributed to this divergence: it said existing generic decoding
+would handle historical optional provenance and required old manifests to load.
+That assumption was false; the baseline store already strictly decoded these
+fields. Repetition in the plan, tests, and documentation does not authorize
+overriding the user's clean-cutover decision.
+
+Required remediation:
+
+- Remove the custom compatibility unmarshaler and retain ordinary strict typed
+  decoding for the new `selected_overlay` representation. Do not add dual fields,
+  special retired-field handling, automatic manifest rewrites, or a format-version
+  bump just for this rename.
+- Replace the historical-acceptance test with coverage for current provenance
+  round trips and unknown/retired provenance rejection through the real store.
+- Correct the plan and current documentation to acknowledge the upgrade effect:
+  manifests with retired provenance require deliberate operator migration before
+  loading. Document narrow removal/renaming of retired informational provenance
+  on a backed-up manifest, preserving execution/checkpoint state; do not advise
+  deleting all session progress or rerunning everything.
+- Keep provenance informational: this correction does not authorize adding it
+  to semantic resume keys or invalidating work based on overlay identity alone.
+
+If transparent historical-manifest acceptance is desired instead, obtain an
+explicit exception to the clean-cutover decision before retaining a compatibility
+reader. Do not treat that exception as already granted.
+
+## Review verification
+
+The following records the original review, before remediation.
+
+- Existing `go test ./...` passed.
+- Race tests passed for subprocess, Audita, Notarius, config, stage, app, and
+  manifest packages after removing the temporary reproduction.
+- `go vet ./...` passed.
+- The temporary direct-YAML regression failed as described above.
+- Source inspection and the new historical-provenance test establish finding 2;
+  `LocalStore.LoadReader` still uses strict decoding outside the custom hook.
+
+The primary architecture is otherwise in place: ConfigKit v0.4.0 overlays,
+shared named credential forwarding/redaction, a v2-only Audita subprocess
+adapter, ordinary reports as diagnostics, and versioned ordered-module polish
+evidence. No live model/provider runs were performed during this review.
+
+## Migration remediation verification
+
+Completed on 2026-09-25. Both new regressions failed before their respective
+fixes. After remediation, `go test ./...`, `go test -race ./...`,
+`go vet ./...`, `go build ./...`, documentation checks, maintained configuration
+example checks, and `git diff --check` passed. No live provider runs were needed.
+
+## Historical completed transcription review
+
+Status: Complete.
+
+Reviewed commits `7b0bf99` through `96b4e73` against the speaker-checkpoint and
+upload-replay roadmap and the original user request. No production changes were
+made during review. The two failures below were reproduced with temporary tests
+using the existing stage fixtures; those temporary tests were removed afterward.
+
+### 1. Reconcile Aggregate State Even When No Speaker Needs HTTP Work
+
+Priority: P2. Status: Complete.
+
+Implemented read-only aggregate identity/evidence checks before resume skips.
+Regression tests cover removed inputs, missing/duplicate/mismatched outputs,
+repair without HTTP requests, downstream invalidation, and exclusion of removed
+speakers from merge without deleting their files. Equivalent path forms and
+output ordering remain reusable. Focused app/stage tests and documentation
+checks pass.
+
+Location: `internal/stage/transcribe_resume.go:21` and the reconciliation result
+consumed there.
+
+`ValidateResume` returns reusable whenever `reconciliation.work` is empty. That
+only establishes that the remaining speakers need no transcription; it does
+not establish that the stored speaker collection and aggregate outputs match
+the current input set. Removing a speaker while the remaining inputs are
+unchanged produces an empty work list, so a succeeded record can be skipped
+without pruning the removed speaker. Its old aggregate output can then remain
+available to merge. Likewise, missing/inconsistent aggregate output references
+are not repaired when all individual checkpoints remain valid. A prepare rerun
+may already stale transcribe in some workflows, but the resume validator cannot
+rely on that to satisfy its own current-input/output checks.
+
+Reproduction: create complete alice/bob checkpoint records and aggregate
+outputs with the existing fixture, mark the stage succeeded, remove bob from
+the manifest's audio inputs, and call `ValidateResume`. It returns reusable
+despite still retaining bob in the stored collection and aggregate outputs.
+
+Required change:
+
+- Distinguish no HTTP work from no reconciliation work. Validate that the
+  committed speaker set and aggregate transcript references represent the
+  reconciled current set, including relevant identity/evidence, before skipping.
+- When only collection/output repair is needed, return non-resumable and let
+  normal execution checkpoint the pruned collection and rebuild aggregate
+  outputs without retranscribing reusable speakers. Preserve existing dependent
+  invalidation; do not force otherwise-current speaker jobs.
+- Keep resume inspection read-only. Do not fix this by deleting incidental
+  transcript files or changing stage selection rules.
+
+Verification: add removed-only input coverage (not just removal combined with
+an added speaker), plus incomplete/inconsistent aggregate output coverage.
+Exercise the runner skip path and assert zero additional WhisperX requests,
+correct rebuilt outputs, and no removed speaker reaching merge.
+
+### 2. Remove the Unrequested Positive Audio-Size Requirement
+
+Priority: P2. Status: Complete.
+
+Audio evidence now permits zero size while still rejecting negative values.
+Regression tests verify zero-size manifest round trips, successful service
+results being checkpointed and reused, and service rejection being propagated
+without creating a completion record. Nonempty valid-JSON output validation is
+unchanged. Both new success regressions failed before the fix.
+
+Location: `internal/manifest/transcribe_state.go:95`.
+
+The new record validator requires `AudioSize > 0`. Previously Narratio accepted
+a regular `.flac` file and delegated transcription acceptance to WhisperX;
+neither the user request nor the roadmap introduced minimum audio size or a new
+audio-content validation policy. Zero-byte content still has a valid checksum
+and can be represented by the checkpoint mechanism. The current check runs
+after a successful response and output materialization, causing the entire
+stage to fail instead of retaining the completed work.
+
+Reproduction: prepare one speaker, replace its prepared audio with an empty
+regular file, and use the existing successful fake WhisperX client. Stage
+execution fails at checkpoint validation with `audio_size must be positive`.
+This demonstrates the extra Narratio restriction; it does not assert that a
+particular production WhisperX deployment accepts empty audio.
+
+Required change:
+
+- Permit zero audio size and reject negative sizes. Keep byte hashing and
+  size equality checks. Let the downstream service decide whether the input
+  can be transcribed, as before.
+- Do not remove the nonempty valid-JSON output requirement, which has a separate
+  existing justification. Do not add a new early empty-audio rejection instead.
+- Update any new tests/documentation that promote strictly positive input size
+  to a contract.
+
+Verification: cover a zero-size record round-trip and successful adapter result
+being checkpointed/reused for that input; retain negative-size rejection and
+ordinary downstream-failure tests.
+
+### Verification After Remediation
+
+Completed on 2026-09-22 with Go 1.26.8: focused stage/application tests,
+changed-package race tests, `go test ./...`, `go test -race ./...`,
+`go vet ./...`, `go build ./...`, `go test ./internal/doccheck`,
+`go test ./internal/config -run '^TestExamplesLoadAndValidate$'`, and
+`git diff --check` all passed. Existing replay and cancellation regression
+tests remain intact; the HTTP adapter required no changes.

+# Resumable Speaker Transcription and Replayable Uploads
+
+Status: Implemented.
+
+## Goal and User Intent
+
+Preserve completed speaker transcriptions when another speaker fails, so an
+ordinary run or resume does not repeat expensive successful work. Separately,
+allow Go's HTTP transport to replay WhisperX uploads when it encounters a
+recoverable connection or stream failure.
+
+The motivating incident exhausted four transcription attempts for one speaker
+after three other speakers had completed. The final error reported an HTTP/2
+peer `PROTOCOL_ERROR` and an inability to replay the request body without
+`Request.GetBody`.
+
+These are related reliability improvements, not a promise to eliminate all
+service failures. This document records the target state and scope. The
+completed implementation sequence is retained in Git history; current behavior
+is documented in the canonical guides linked below.
+
+## Pre-implementation Limitations
+
+The [transcribe stage](../internal/stage-transcribe.md) writes successful
+responses into the invocation's run directory. It installs canonical transcripts
+and returns its per-file metadata only after every speaker succeeds. A failure
+therefore leaves no durable per-speaker progress that ordinary resume can use,
+even though some completed JSON files may remain on disk.
+
+The [WhisperX adapter](../integrations/whisperx.md) already retries requests at
+the application level, reopening audio for each attempt. Its multipart request
+body is streamed through a pipe and has no replay callback. Transport-level
+recovery within an attempt cannot reconstruct a consumed body. Providing that
+capability addresses the replay limitation, not the underlying peer protocol
+error; persistent failures can still require service or proxy investigation.
+
+## Targeted End State
+
+### Durable Per-Speaker Completion
+
+Each successfully transcribed speaker file is validated, saved, and recorded
+durably before that work is treated as reusable. The session manifest remains
+the progress authority. Follow the existing analyze-stage checkpoint pattern
+without turning speakers into pipeline stages or introducing a general task
+engine.
+
+Ordinary execution reconciles the current prepared audio set with recorded
+speaker results. It reuses valid completed work and schedules failed,
+unattempted, missing, or obsolete results. A result is not reusable merely
+because a matching filename exists. Evidence binds it to the speaker/audio
+identity, audio content, Narratio-visible recognition settings, and the saved
+transcript's integrity.
+
+The relevant recognition settings remain the WhisperX service URL and language.
+Retry count/delay, concurrency, timeout, credentials, and diagnostic locations
+remain operational settings rather than reasons to discard completed results.
+Changes to private service models or configuration remain an operator reason
+to force transcription; Narratio does not inspect the service's private state.
+
+Changes to individual audio inputs require replacement of affected results,
+not automatic retranscription of unrelated unchanged speakers. New speakers
+need transcription; removed speakers do not remain in the current aggregate
+output set. Records must describe the inputs actually used, not grant reuse to
+old bytes under a changed identity.
+
+### Aggregate Completion, Failure, and Force
+
+The overall stage succeeds only when every currently required speaker has a
+validated, durably recorded result. Incomplete per-speaker progress does not
+make the aggregate stage successful or authorize downstream consumption of an
+incomplete collection. Existing dependent-stage invalidation remains in effect.
+
+Retain bounded concurrency and the current fail-fast behavior: a speaker
+failure cancels outstanding work. Results already checkpointed remain reusable
+after failure, cancellation, or process interruption. A later ordinary run or
+resume retries the remaining work; it does not need a new CLI command.
+
+Checkpoint writes must be serialized so concurrently finishing speakers cannot
+overwrite each other's progress. A failed persistence operation must not
+advertise an unrecorded result as complete. Previously committed progress remains
+the recovery authority, and checkpoint errors must be surfaced rather than
+reported as successful transcription.
+
+`--force` on transcribe regenerates all currently required speakers instead of
+reusing their prior completions. Successful replacements are checkpointed too,
+so an ordinary retry after a failed forced invocation can retain the newly
+completed work. Old results for speakers not successfully regenerated must not
+satisfy that unfinished forced replacement on the next ordinary retry.
+
+This deliberately relaxes the current all-speakers-before-canonical-installation
+implementation: individual durable results may exist while the stage remains
+failed or incomplete. The all-speakers-before-stage-success boundary remains.
+
+### Replayable WhisperX Requests
+
+Provide `Request.GetBody` so the HTTP transport can obtain a fresh body for the
+same request. Replay reopens the audio and reproduces the multipart boundary,
+filename, fields, and framing used by the original request. Independent bodies
+must not share a consumed reader or mutable read position.
+
+Preserve bounded-memory streaming rather than buffering entire audio files in
+memory. Correctly close every original and replay body and its audio resources;
+preserve source-read errors and cancellation, including partial uploads and
+early server responses. Successful response handling must not accidentally wait
+on, or report errors solely from, an abandoned body instead of the replay that
+produced the response.
+
+Keep the existing application-level retry count, delay, classification, and
+per-attempt timeout semantics. Transport replays occur within an application
+attempt and its context; they are not additional Narratio-configured attempts.
+Do not add another custom retry loop, silently increase retries, or disable
+HTTP/2 globally as a substitute for replay support.
+
+The adapter still validates and installs only successful JSON responses.
+Request replay does not provide exactly-once server execution: a lost response
+can cause repeated transcription work, as can existing application retries.
+No new service-side idempotency protocol is required by this feature.
+
+## Required Change Areas
+
+- **Manifest and persistence:** Add transcribe-owned per-speaker progress and
+  evidence, with safe checkpoint updates and preservation through runner failure
+  handling. Review manifest validation, copying, serialization, and existing
+  publish/restore handling wherever the new records pass through those paths.
+- **Stage execution and reuse:** Reconcile speaker records before scheduling,
+  checkpoint validated completions, rebuild aggregate outputs from the current
+  set, and account for partial progress in ordinary and forced execution.
+  Review successful-stage reuse as well as failed-stage retries so stale audio
+  or missing/corrupt transcript evidence is not bypassed by an aggregate skip.
+- **Artifact lifecycle:** Use existing path, installation, integrity, and manifest
+  mechanisms. Ensure checkpointed results do not depend on an ephemeral run
+  directory surviving cleanup. Do not introduce a second authoritative ledger
+  or infer completion by scanning abandoned runs.
+- **HTTP adapter:** Make multipart bodies reproducible and correctly manage
+  every replay's lifetime, without changing the WhisperX HTTP schema or requiring
+  an upstream service change.
+- **Tests:** Cover per-speaker recovery after a later failure, interruption and
+  checkpoint failure; changed/missing inputs or outputs; force followed by an
+  ordinary retry; concurrent successful completions; and aggregate downstream
+  gating. Extend existing fixtures rather than duplicating analyze's complete
+  test suite. Exercise actual body reconstruction after partial consumption,
+  multipart equivalence, cancellation/resource cleanup, and existing bounded
+  streaming and retry behavior—not just the presence of a callback. Default
+  tests remain offline and use local/fake HTTP boundaries, never paid services.
+- **Documentation:** Update the canonical
+  [stage guide](../internal/stage-transcribe.md),
+  [manifest guide](../internal/manifest.md),
+  [WhisperX contract](../integrations/whisperx.md),
+  [operations guide](../operations.md), and
+  [troubleshooting guide](../troubleshooting.md) when implemented. Explain
+  partial completion, ordinary retry versus force, and the distinction between
+  request replay limitations and persistent peer protocol failures.
+
+## Compatibility and Scope Boundaries
+
+Existing speaker identities, raw transcript formats, and the fixed pipeline
+order remain unchanged. Existing manifests remain readable, but must not be
+treated as containing per-speaker evidence they never recorded. Recovery relies
+on verified recorded evidence, not guessed associations between old transcripts
+and current audio. No general legacy-migration framework is part of the feature.
+
+Automatic adoption of unrecorded outputs from previously failed runs is outside
+this feature. Such files may be recoverable after verifying their inputs, but
+their presence alone does not prove completion. No recovery/import command,
+speaker-selection CLI, historical invocation ledger, new service configuration
+discovery, or broader orchestration refactor is included.
+
+The feature does not diagnose the remote service/proxy's underlying HTTP/2
+problem, guarantee recovery from persistent protocol errors, or change the
+policy for continuing unrelated work after failure.
+
+## Completion Criteria
+
+For speakers A, B, C, and D: if A and B are checkpointed, C fails, and D has not
+completed, ordinary resume retains A and B, retries C, and completes D. No
+downstream stage receives an incomplete successful transcription collection.
+Force replaces all four, while an ordinary retry can reuse checkpoints from
+that forced replacement attempt.
+
+The HTTP transport can reconstruct the upload after consuming the original
+body, without whole-file memory buffering, lost source errors, or stranded
+upload resources. A persistent peer error still fails normally after the
+configured application attempts, without discarding checkpointed speakers.

+## Transcription retries speakers that previously finished
+
+Symptom:
+
+- an ordinary transcribe retry calls WhisperX for a speaker that appeared to
+  finish earlier; or
+- an older successful session retranscribes all speakers once after upgrade.
+
+Likely causes:
+
+- the earlier response or canonical file was not followed by a successful
+  speaker manifest checkpoint;
+- the prepared audio bytes/path, WhisperX URL, or language changed;
+- the canonical transcript is missing, unsafe, non-regular, invalid JSON, or
+  no longer matches its recorded size/checksum;
+- the previous invocation used `--force`, which durably cleared pre-force

+- the manifest has only legacy aggregate transcribe state and cannot bind old

+

+
+- inspect the reported speaker and filesystem error, repair the prepared input

+  the same configured URL, but Narratio still considers speaker transcripts
+  current.
+

+- Narratio can fingerprint its configured URL and language, not private state

+## Transcription manifest checkpoint failed
+
+Symptom:
+
+- transcribe reports that a speaker completed but the session manifest could
+  not be saved.
+
+Likely causes:
+
+- the workspace is unwritable or out of space;
+- the manifest path or parent directory is unsafe or the wrong type; or
+- a transient filesystem error interrupted atomic replacement.
+

+
+- correct the reported filesystem or permission problem and retry transcribe
+  normally. Narratio reconciles from the last readable collection and reuses

+## Notarius credential reference unavailable
+
+Symptom:
+
+- configuration loading reports `secret.unset`, `secret.empty`, or an invalid
+  name in `pipeline.notarius.credentials`, including during inspection or a
+  run that would not execute extraction.
+
+Likely causes:
+
+- the named environment variable is absent or empty;
+- the selected secrets directory lacks a file with that exact name;
+- a process environment variable exists but is empty, so bootstrap correctly
+  leaves it in place; or
+- the Narratio reference name does not match `api_key_env` in the selected
+  Notarius/PromptKit profile.
+
+Safe fix:
+
+- set the exact nonempty environment variable or provide an equivalently named
+  file through the conventional or explicit secrets directory;
+- remove, set to `null`, or set to `[]` when that deployment needs no credential;
+  and
+- use `config show`, `config sources`, and `config diff` to inspect the public
+  reference name and ownership without exposing its value.
+
+Narratio resolves selected credential references during ordinary pipeline
+loading, before stage selection or resume. Credential changes alone do not
+invalidate a completed extraction, but the current reference must still resolve
+for the command to proceed.

+
+## Audita v2 configuration or credential failure
+
+Symptom:
+
+- Narratio rejects a retired `pipeline.audita` field during loading, reports
+  `secret.unset` or `secret.empty` for a listed credential, or Audita rejects
+  its external configuration or selected profile when polish runs.
+
+Likely causes:
+
+- the Narratio pipeline still uses v1 endpoint, model, capacity, singular key,
+  report, or retention settings;
+- the named key is missing or empty, including a present but empty process
+  environment variable that takes precedence over a secrets-directory file;
+- Audita's external v2 file references a backend credential name not forwarded
+  by `pipeline.audita.credentials`, including a backend not selected by the
+  current profile; or
+- an Audita overlay or profile selector names a missing downstream definition.
+
+Safe fix:
+
+- follow the [migration table](./operations.md#migrating-audita-and-provider-credentials)
+  and use a supported Audita v2 executable and configuration;
+- provide each needed provider-named variable through the environment or
+  secrets directory, and list that same name in `pipeline.audita.credentials`;
+- validate the external file offline with
+  `audita config validate --config <file>` before switching executables; and
+- inspect Audita's effective profile selection separately from Narratio's
+  `config show`. Narratio does not infer downstream selectors.
+
+An exit-zero polish with a valid transcript succeeds even when Audita reports
+recoverable errors or no corrections. Missing reports are allowed when Audita
+reporting is disabled externally. Edits to Audita-owned files behind unchanged
+selectors require `narratio run-stage polish <session-id> --force` to replace a
