+### 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.

+### Transcription continuation and replacement
+
+Transcribe checkpoints each validated speaker independently. If a later
+speaker exhausts HTTP retries, the process is canceled, or the aggregate stage
+save fails, the aggregate stage is not successful and downstream merge cannot
+consume the partial set. The last successfully saved speaker records and their
+canonical `transcripts/raw/<speaker>.json` files remain durable, however.
+
+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
+speakers. A changed audio file replaces only its speaker; a changed WhisperX
+URL or language makes every current speaker non-reusable. Retry, timeout, and

+
+Force durably clears the reusable collection before sending requests. If that
+forced attempt fails, a later ordinary retry reuses only replacement speakers
+checkpointed after the reset; it does not revive pre-force results. Do not edit
+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
+identifier is unchanged, but older strict-decoding Narratio binaries may reject
+a manifest after current Narratio writes the additive speaker fields; retain a
+backup or complete the upgrade before relying on downgrade.
+
+Restoring a manifest does not implicitly publish or restore every raw speaker
+file. If a recorded canonical transcript is absent locally, ordinary
+reconciliation schedules that speaker again. Removing run directories does not

+`effective_config.selected_profile` are rejected by strict decoding; Narratio
+does not silently discard or translate that retired field.
+
+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.model`, `validation_model` | Audita PromptKit profile files; optionally select them from Narratio with `audita.proposal_profile` and `validation_profile` |
+| `audita.llm_api_key` | `audita.credentials: [PROVIDER_KEY_NAME]`, matching each Audita backend's `credential` name |
+| `notarius.llm_api_key` | `notarius.credentials: [PROVIDER_KEY_NAME]`, matching references in Notarius-owned profiles |
+| `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
+backends, including those not currently selected. Notarius looks up its own
+profiles; Narratio does not discover their credential names. Credential lists
+may be cleared with `[]` in a Narratio overlay.
+
+Prepare the external file from Audita's maintained
+[local example](https://gitea.maximumdirect.net/eric/audita/src/tag/v2.0.0/examples/minimal-config.yml),

+and [v2 migration guide](https://gitea.maximumdirect.net/eric/audita/src/tag/v2.0.0/docs/migrations/v2.md).
+Before switching the executable, validate the file offline:
+
+```bash
+audita config validate --config /usr/local/etc/audita/config.yml
+```
+
+Use `audita config print-effective --config /usr/local/etc/audita/config.yml --view profiles`
+to inspect downstream profile selection without contacting a provider. For a
+production Audita configuration, leave ordinary reports enabled
+and debug disabled unless an operator deliberately chooses otherwise; Narratio
+does not override those settings. Audita writes `errors.yml`, `recoveries.yml`,
+and `report.md` beside the polished output when reporting is enabled. An
+exit-zero run with a valid transcript succeeds even if those reports describe
+recoverable errors or no applied corrections. See the [Audita integration
+contract](./integrations/audita.md) for report placement and limits.
+
+Narratio's polish resume evidence tracks selected config path, Audita overlay,
+profiles, ordered modules, description, schema, and output identity. Editing
+Audita-owned files behind unchanged selectors is invisible to Narratio; force

+# 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.

+## Prerequisites and publication scope
+
+Use a checkout on `main` with Git authentication permitting fetches and pushes

+before offline validation. No model/provider credentials are needed. Gitea

+# 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.

+`.DS_Store` during secrets bootstrap. These entries no longer block otherwise
+valid credentials from loading and are omitted from bootstrap reports.
+
+## Compatibility
+
+This is a backward-compatible dependency bug fix. Configuration schemas,

+# 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.

+# Narratio v2.2.1

+
+## Summary
+
+Transcribe and analyze now share one internal operation for preparing isolated
+checkpoint candidates, saving them, and promoting successfully saved progress
+into live state. Each stage retains its own progress model and recovery policy.
+
+## Compatibility
+
+CLI commands, configuration, manifest schemas, artifact formats, and external

+# 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.

-# ConfigKit Adoption and Platform Simplification
-
-**Status:** Accepted; implementation pending
-
-## Purpose
-
-Narratio currently owns a substantial YAML configuration subsystem for strict
-decoding, explicit imports, additive composition, profile overlays, presence
-tracking, provenance, and effective-value inspection. ConfigKit was extracted
-from this implementation and now provides those generic responsibilities as a
-maintained library.
-
-Narratio 2.0 will adopt ConfigKit as its configuration foundation, remove the
-superseded generic infrastructure, and retain only Narratio-specific configuration
-policy and domain resolution. The same major release will narrow the supported
-platform set to the systems that Narratio is expected to run on in practice.
-
-This roadmap defines the desired contracts and end state. The
-[implementation plan](implementation.md) owns sequencing and completion gates.
-
-## Goals
-
-- Reduce Narratio-owned configuration code and tests by delegating generic YAML
-  mechanics to ConfigKit.
-- Establish one strict and explainable configuration lifecycle rather than
-  retaining parallel or compatibility loaders.
-- Preserve Narratio's application-specific defaults, validation, campaign/session
-  resolution, party handling, artifact-family expansion, digests, and CLI policy.
-- Make individual artifact definitions easy to organize, identify, inspect, and
-  reuse as dependencies of later artifacts.
-- Keep raw credentials out of YAML and adopt a predictable secrets-directory
-  convention that works before configuration loading.
-- Remove unsupported platform code and release obligations that provide no known
-  user value.
-- Deliver the resulting contract changes as Narratio v2.0.0 with a clear migration
-  guide.
-
-## Platform Contract
-
-Narratio's v2 platform matrix is:
-
-| Platform | Status | Required evidence and deliverables |
-| --- | --- | --- |
-| Linux amd64 | Primary, supported | Default tests, race checks, static analysis, build validation, and a release asset |
-| Linux arm64 | Primary, supported | Cross-build validation and a release asset; native validation is used when an appropriate runner is available |
-| macOS arm64 | Best effort | Cross-build validation and a release asset; native CI and platform-equivalent runtime guarantees are not required release gates |
-| macOS amd64 | Unsupported | No build gate, release asset, compatibility promise, or platform-specific maintenance |
-| Windows | Unsupported | No build gate, release asset, compatibility promise, or platform-specific maintenance |
-
-Windows- and Intel-Mac-specific code, tests, CI entries, release packaging, and
-documentation are removed when they no longer serve a supported build. Portable
-code should remain portable where doing so is natural, but accidental compilation
-on an unsupported target does not create a support commitment.
-
-Best-effort macOS arm64 support means Narratio intends to keep the target buildable
-and will consider reported defects when practical. Lack of a native runner or an
-unverified platform-specific behavior does not block a release. A target for which
-Narratio publishes an asset must still pass its configured cross-build gate.
-
-## ConfigKit Dependency and Ownership
-
-Narratio will depend on the tagged ConfigKit module at an exact reviewed version,
-initially `gitea.maximumdirect.net/eric/ConfigKit@v0.1.1`. ConfigKit is pre-1.0 and
-may make compatibility changes in later minor versions, so dependency upgrades are
-intentional changes accompanied by contract review and focused Narratio integration
-tests; Narratio does not follow an unpinned branch or automatically accept a newer
-minor release.
-
-ConfigKit owns:
-
-- bounded file, byte, and reader input;
-- the accepted YAML syntax and strict typed decoding;
-- import declarations, traversal, containment, and resource limits;
-- additive composition and conflict attribution;
-- selected-profile overlay semantics;
-- explicit input presence and source provenance;
-- application-default and recorded-resolution coordination;
-- structured configuration diagnostics;
-- secret-reference parsing and resolution;
-- secrets-directory loading and its safe report; and
-- detached effective configuration inspection supplied by its public result.
-
-Narratio owns:
-
-- pipeline, campaign, session, party, and runtime domain types;
-- configuration-file discovery and CLI selection;
-- concrete defaults, normalization, and semantic validation;
-- campaign/session identity and stable-input resolution;
-- canonical party parsing requirements and authored-byte retention;
-- character artifact-family expansion and generated ownership attribution;
-- root-relative interpretation of Narratio-owned runtime paths;
-- effective pipeline digests and semantic profile diffs;
-- command output and exit behavior; and
-- adapter and runtime initialization after configuration succeeds.
-
-Narratio must use ConfigKit through its public package. It must not import
-ConfigKit's private YAML implementation or reproduce ConfigKit's parser,
-composition, profile, provenance, or secret-bootstrap mechanics locally.
-
-## Configuration Format
-
-Narratio adopts ConfigKit's configuration conventions directly. The old Narratio
-`composition:` envelope, declared profile catalog, arbitrary overlay paths, and
-`composition.default_profile` are removed without a compatibility parser.
-
-The root pipeline uses `configkit.imports` declarations. Import paths, optional
-imports, globs, recursion, ordering, composition conflicts, containment, and limits
-have the meanings defined by the pinned ConfigKit contract. Narratio does not add a
-second import syntax or narrower application-specific traversal implementation.
-
-The unoverlaid root and its imports are the production configuration. A named
-profile is a ConfigKit overlay at `profiles/<name>.yml`; in particular,
-`profiles/testing.yml` contains inexpensive-model overrides and testing-only
-artifacts. Omitting `--profile`, or selecting ConfigKit's `default` profile, uses the
-production base. `--profile testing` applies the testing overlay. Narratio does not
-maintain a separate configured default-profile mechanism or validate unselected
-profile files.
-
-ConfigKit's rules for explicit false, zero, empty, and null values replace
-Narratio's custom presence tracking. Application defaults and normalization use a
-ConfigKit definition and recorded resolution where the final value depends on
-whether input was present. `NormalizeConfig.UnmarshalYAML` and equivalent
-parser-coupled application hooks are removed.
-
-Pipeline, campaign, session, and party inputs use the common ConfigKit loading
-boundary where its schema model can represent their types. Narratio may perform
-narrow pre- or post-load domain work, such as retaining authored party bytes,
-rejecting unresolved session-template placeholders, resolving stable inputs, and
-expanding artifact families. Such work must not recreate a second generic YAML
-loader.
-
-## Artifact Definition Ergonomics
-
-The canonical v2 configuration layout defines each ordinary Scriptorium artifact
-in its own file under `artifacts/`. The root pipeline imports the directory through
-ConfigKit, for example:
-
-```yaml
-configkit:
-  imports:
-    - glob: artifacts/*.yml
-```
-
-Each file contributes one ordinary entry at
-`scriptorium.artifacts.<artifact_key>`. The map key is the authoritative Narratio
-artifact key and therefore makes the artifact's internal identity explicit in the
-definition itself:
-
-```yaml
-# artifacts/session_recap.yml
-scriptorium:
-  artifacts:
-    session_recap:
-      enabled: true
-      prompt_id: dnd.session_recap
-      output_path: artifacts/session_recap.md
-```
-
-The canonical reusable source ID is derived without another configured identifier:
-`session_recap` becomes `narratio.artifact.session_recap`. The recommended filename
-is `<artifact_key>.yml`, but the filename is organizational rather than an identity
-source. Renaming or moving a file without changing its map key does not change the
-artifact contract. ConfigKit additive composition rejects duplicate artifact keys.
-
-The one-artifact-per-file layout is the documented happy path and is used by
-maintained examples. Narratio does not prohibit an inline artifact or another
-ConfigKit-compatible source organization merely because it differs from that
-layout. Artifact identity always comes from the effective map key, never implicitly
-from a filename or import position.
-
-Artifact families use the corresponding `artifact-families/*.yml` convention, with
-one `scriptorium.artifact_families.<family_key>` entry per file. The family key is
-explicit. Concrete member keys and source IDs continue to use Narratio's existing
-deterministic family/member naming rule after canonical party resolution.
-
-Narratio adds a read-only `narratio config artifacts` command using the ordinary
-pipeline, profile, and campaign selectors. It reports every effective ordinary
-artifact's key, canonical `narratio.artifact.<key>` source ID, defining source,
-enabled state, output path, and effective dependencies. Generated family members
-also report their family origin. Output ordering is deterministic by artifact key,
-and the command does not require a session or initialize runtime adapters.
-
-A configured-artifact input creates an implicit dependency on the referenced
-artifact. For example:
-
-```yaml
-inputs:
-  recap:
-    source: narratio.artifact.session_recap
-```
-
-The effective dependency graph is the union of explicit `depends_on` entries and
-dependencies inferred from `narratio.artifact.<key>` inputs. Inferred and explicit
-duplicates collapse to one dependency. `depends_on` remains available for an
-ordering requirement when the upstream output is not supplied as an input.
-Validation applies the same existence, self-reference, and cycle rules to both
-kinds of dependency, and diagnostics identify the declaration or input that
-introduced an invalid edge. Operators no longer need to repeat an artifact input in
-`depends_on` merely to make that input valid.
-
-## Effective Inspection, Digests, and Profile Diff
-
-ConfigKit results are the authority for composed input presence, base/profile
-origins, diagnostics, and the initial typed effective configuration. Narratio's
-configuration commands adapt those results to existing application-facing command
-formats rather than exposing ConfigKit implementation types directly.
-
-Party-dependent artifact families are expanded only after the selected campaign and
-canonical party are known. That derived state is intentionally outside ConfigKit's
-completed load snapshot. Narratio retains a narrow application-owned layer that:
-
-- records generated family/member and publish-rule attribution;
-- projects the final post-expansion pipeline for operator inspection;
-- recomputes the effective pipeline digest after expansion; and
-- ensures stages and adapters receive only the final concrete configuration.
-
-Narratio continues to own semantic `config diff` behavior because ConfigKit does
-not provide configuration diffs or fingerprints. Each side of a profile comparison
-may be loaded independently through ConfigKit. The former guarantee that both sides
-come from one parsed source snapshot is removed; operators must not rely on a
-meaningful comparison while concurrently modifying its source files. Equality is
-still based on normalized effective values rather than YAML formatting or source
-layout.
-
-## Credential and Secrets Convention
-
-Raw API keys and other credential values remain prohibited in pipeline, campaign,
-session, generated configuration, manifests, diagnostics, examples, and logs.
-Credential-bearing configuration fields use ConfigKit secret references: YAML
-contains an environment-variable name, while the resolved value remains available
-only through ConfigKit's trusted typed boundary. Fields should use credential names
-rather than legacy names ending in `_env` when the v2 schema is updated.
-
-The `pipeline.secrets.env_dir` stanza is removed. Narratio selects a secrets
-directory before parsing the pipeline using this precedence:
-
-1. an explicitly supplied `--secrets-dir PATH`; otherwise
-2. the `secrets` subdirectory beside the selected root pipeline file.
-
-The conventional directory is derived from the resolved root pipeline path, never
-from the current working directory, an imported file, or a selected profile. A
-relative explicit CLI path is resolved from the caller's current working directory,
-consistent with an ordinary command-line path argument.
-
-If an explicitly selected directory is missing or invalid, the command fails with a
-clear bootstrap diagnostic. If the conventional directory is absent, Narratio
-performs no directory bootstrap and continues; pre-existing environment variables
-may satisfy all references. If the conventional directory exists but ConfigKit
-rejects or cannot read it, the command fails. Already-set environment variables,
-including empty values, retain ConfigKit's documented precedence.
-
-Narratio explicitly calls `configkit.LoadSecretsDir` at most once for a command,
-before the first ConfigKit load that may resolve secret references and before any
-concurrent work or runtime client initialization. This application-level convention
-does not make ConfigKit's ordinary `Load` mutate process-global state. The bootstrap
-report is rendered or summarized through a safe Narratio command boundary without
-secret values.
-
-Narratio adopts ConfigKit's secret-directory rules and limits without restoring its
-old permission-mode, selected-directory-symlink, invalid-entry, byte-limit, or
-newline-trimming behavior through compatibility wrappers. Configuration inspection
-may require the referenced environment variables or the selected secrets directory
-because an ordinary successful ConfigKit load resolves effective typed secret
-references. Inspection output may show non-secret reference names where appropriate,
-but must never expose resolved values.
-
-## Validation and Diagnostics
-
-Narratio's semantic rules remain recognizable application code registered with the
-appropriate ConfigKit definition. Validation continues to reject invalid pipeline,
-campaign, session, party, adapter, publish, and artifact relationships before
-runtime work where practical. Validation order and exact prose are not compatibility
-contracts.
-
-ConfigKit diagnostic codes, paths, and source locations should be preserved through
-the application error boundary where useful. Narratio adds command context and exit
-classification but does not parse ConfigKit error strings or expose raw parser
-errors. Secret values must remain absent from success and failure diagnostics.
-
-## Compatibility and Migration
-
-This work intentionally changes supported platforms, pipeline composition syntax,
-profile layout and selection, secret configuration, YAML semantics, diagnostics,
-and some inspection prerequisites. It is released as Narratio v2.0.0.
-
-There is no runtime compatibility layer for the old `composition` or
-`pipeline.secrets` syntax. Maintained examples are converted to the ConfigKit
-format, and the v2 release documentation provides a concise migration guide that
-covers:
-
-- converting imports to `configkit.imports` declarations;
-- folding the production overlay into the base configuration;
-- placing testing overrides in `profiles/testing.yml`;
-- moving ordinary artifacts and artifact families into the recommended individual
-  definition files and using their map keys as canonical identities;
-- removing redundant `depends_on` entries when a configured-artifact input now
-  supplies the same dependency;
-- moving secret files to the conventional sibling `secrets/` directory or using
-  `--secrets-dir`;
-- renaming credential-reference fields where applicable;
-- ConfigKit's stricter YAML and explicit-value semantics;
-- the independent-load behavior of `config diff`; and
-- the removal of Windows and macOS amd64 artifacts.
-
-Obsolete application implementation, tests, documentation, examples, CI paths, and
-release machinery are removed rather than left deprecated inside the v2 codebase.
-
-## Required Changes
-
-- Add and pin the ConfigKit module dependency and establish a small application
-  integration boundary for definitions, result adaptation, and diagnostics.
-- Replace Narratio's generic YAML parsing, composition, import, profile, presence,
-  and provenance implementation with ConfigKit public APIs.
-- Express existing defaults, presence-sensitive normalization, and semantic
-  validation through ConfigKit definitions without moving Narratio domain policy
-  into the library.
-- Adapt pipeline/campaign/session/party loading and preserve the existing
-  application resolution steps that occur after their independent typed loads.
-- Rework effective configuration, sources, and diff commands around ConfigKit
-  results plus Narratio's post-party generated-attribution layer.
-- Add the maintained per-artifact and per-family file layouts, the read-only
-  `config artifacts` catalog, and effective dependency inference from configured
-  artifact inputs.
-- Convert credential configuration to typed references, add the common
-  `--secrets-dir` option, implement conventional-directory selection, and replace
-  the custom API-key directory loader with `configkit.LoadSecretsDir`.
-- Update adapters to consume resolved credentials or safe environment reference
-  names from typed configuration without independently rediscovering secret values.
-- Remove Windows and macOS amd64 build targets, release assets, CI entries,
-  platform-specific implementation, and obsolete tests and documentation.
-- Convert maintained examples and add v2 migration and release documentation.
-- Retain focused Narratio tests for domain policy and assembled application
-  behavior while deleting parser/composer/bootstrap mechanism tests now owned by
-  ConfigKit. Tests remain deterministic, offline, credential-free, and aligned with
-  the repository testing policy.
-- Update canonical architecture, configuration, CLI, operations, development,
-  internal, troubleshooting, and release documentation only as the corresponding
-  behavior is implemented.
-
-## Target End State
-
-Narratio v2.0.0 has one configuration infrastructure dependency and no duplicate
-YAML composition subsystem. Operators maintain a production base configuration,
-optional explicit imports, and fixed named overlays such as `testing`. ConfigKit
-provides strict parsing, composition, typed loading, provenance, diagnostics, and
-credential resolution; Narratio supplies domain meaning and its post-campaign
-artifact expansion.
-
-Operators can add an artifact by creating one discoverable YAML file whose map key
-is its stable Narratio identity. `config artifacts` exposes that key, its canonical
-source ID, origin, output, and effective dependency set. A later artifact can reuse
-the output through `narratio.artifact.<key>` without repeating the same edge in
-`depends_on`, while explicit ordering-only dependencies remain supported.
-
-Secrets normally live in a predictable `secrets/` directory beside the selected
-pipeline, with `--secrets-dir` available for deployment-specific placement. Raw
-credential values never enter YAML or inspection output. The bootstrap is explicit
-in application startup and ordinary ConfigKit loading remains free of process-global
-mutation.
-
-Release and CI maintenance covers Linux amd64 and arm64 as the primary platforms
-and macOS arm64 on a best-effort basis. Windows and macOS amd64 carry no remaining
-support or release burden. The repository contains no legacy configuration parser,
-profile compatibility layer, obsolete platform implementation, or redundant tests
-for behavior owned by ConfigKit.
-
-## Deferred Work
-
-- A ConfigKit reference-only inspection or typed prepare/finalize lifecycle may be
-  considered upstream if credential-free inspection becomes a demonstrated shared
-  requirement. Narratio does not implement a private substitute in this migration.
-- ConfigKit hot reload, remote providers, automatic configuration migration, and
-  application command frameworks remain outside Narratio's scope.
-- Native macOS arm64 CI may be added later when a reliable runner is available; it
-  is not required for v2.0.0.

+# 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.

-# ConfigKit Adoption Implementation Plan
+# Implementation Plan: Audita v2 and Shared Provider Credentials
 
-Status: Complete
+Status: Complete (2026-09-25).
 
-Implement the [ConfigKit adoption roadmap](configkit-adoption.md) in the order
+## Scope and working instructions
-below. The target is Narratio v2.0.0: ConfigKit v0.1.1, the reduced platform
-matrix, and the artifact-authoring workflow described there. Each stage is a
-bounded implementation assignment for a gpt-5.6-terra coding agent. Mark a stage
-complete only after its changes and acceptance checks succeed; record a short
-completion and verification note beside its status.
 
-## Instructions for every stage
+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.

+release.
-  cache for v0.1.1 is an alternative. Do not require a sibling checkout, a local
-  `replace`, a Go workspace, an upstream patch, or an unpinned revision to build.
-- Keep Narratio domain policy in `internal/config`, startup and selectors in
-  `internal/app`, and credential delivery in the owning adapters. Do not build
-  a general configuration framework around ConfigKit.
-- Keep each stage buildable and run focused behavioral tests for its changed
-  boundary. Temporary migration helpers may exist between stages only where
-  named here; they must not introduce runtime format auto-detection or fallback.
-- Update each canonical current-behavior document when its behavior changes.
-  The roadmap remains the owner of unimplemented work. Preserve historical
-  release notes; their descriptions of old platforms and formats are history.
-- Tests use real ConfigKit and temporary files, with fake external adapters or
-  storage where needed. Use synthetic credentials and isolate environment
-  mutation; such tests must not run in parallel. Retain domain and security
-  coverage, remove superseded mechanism tests, and avoid exact diagnostic prose
-  or private callback choreography assertions.
-- Do not tag or publish v2.0.0 as part of this plan. Release preparation belongs
-  here; release authorization and tag publication are a later task. The existing
-  release completion boundary remains successful upstream tag push, with no CI
-  polling or waiting.
 
-## Decisions that apply across stages
+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 roadmap is authoritative for product scope. These implementation choices
+The user approved a clean cutover: no Audita v1 runner, deprecated aliases,
-make that scope concrete:
+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.
 
-- Enable ConfigKit imports and profile selection for pipeline files only.
+## Selected design
-  Campaign, session, and party are single-source definitions with imports and
-  profiles disabled. Preserve their domain schemas and source-relative inputs.
-  Omitted or empty profile and the exact name `default` select the base; other
-  names use ConfigKit's fixed `profiles/<name>.yml` convention.
-- Defaults apply to absent fields. Explicit empty/zero/false/null values follow
-  ConfigKit decoding and then domain validation; do not refill invalid explicit
-  values with legacy defaults. Optional null stage sections remain absent;
-  required sections fail domain validation rather than being resurrected.
-- Keep ConfigKit metadata/result snapshots separate from runtime-only Narratio
-  state. ConfigKit discards ignored and unexported fields when detaching values;
-  attach root paths, retained party bytes, family catalogs, and digest metadata
-  after loading. No validator may mutate bound configuration.
-- Use one Narratio-owned safe effective projection for the final expanded
-  pipeline. It contains configuration values and credential reference names,
-  never resolved credential bytes. It feeds show, semantic diff, digest, and
-  catalog data. ConfigKit metadata remains the authority for input provenance;
-  Narratio adds only domain-generated attribution.
-- Rename `storage.s3.access_key_id_env` to `access_key_id`,
-  `storage.s3.secret_access_key_env` to `secret_access_key`, and
-  `audita.llm_api_key_env` to `llm_api_key`. Each is an optional `*configkit.Secret`.
-  An explicit reference always resolves during loading, even if the associated
-  stage will not execute. Require both S3 fields together or neither. With neither,
-  retain the AWS SDK default credential chain; do not synthesize mandatory secret
-  references that would break role-based authentication or local-only inspection.
-  With no Audita reference, preserve its existing downstream credential discovery.
-  Explicit references replace Narratio's old per-adapter environment lookup.
-- Keep absent S3 credentials out of defaults; migration examples explicitly name
-  the existing AWS variables when static credentials are intended. A non-nil
-  missing/empty reference fails instead of silently falling back. This preserves
-  provider-managed credentials while making explicit configuration trustworthy.
-- `config artifacts` uses the existing configuration command selectors and text
-  output convention. No new JSON mode, artifact creation wizard, inferred filename
-  identity, or profile catalog is added.
-- Preserve the roadmap's unique base artifact definition rule explicitly:
-  ConfigKit rejects conflicting leaves but can compose disjoint children of the
-  same mapping. Use its public source metadata to reject an ordinary artifact key
-  declared by multiple base files, even if their fields are disjoint. Apply the
-  same rule to family keys. A selected profile may override or extend a definition.
-  This is a narrow Narratio declaration rule, not a different merge algorithm.
-- Relax only the obsolete configuration/secrets filesystem restrictions identified
-  by the roadmap. Do not remove session restore, cleanup, publication, workspace
-  confinement, or ordinary shared-workspace mode guarantees as collateral work.

-## Stage 2 — Separate configuration normalization from validation
+### Configuration and credentials
 
-Status: Complete — Added explicit deterministic pipeline normalization before
+- Both `pipeline.audita.credentials` and `pipeline.notarius.credentials` are

+  lists of ConfigKit secret references. Use `[]configkit.Secret`; each element
-documented the boundary, and verified config race tests plus app/stage consumers.
+  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.
 
-Read: `internal/config/load.go`, `defaults.go`, `normalize.go`, `validate*.go`,
+### Invocation, reports, and failure
-`artifact_families.go`, and ConfigKit's “Recorded application resolution”,
-“Semantic validation”, and “Defaults and typed decoding” contracts.
 
-1. Separate value-producing normalization from read-only validation, including

-   mutations, including changes that would occur only on error paths.
+Remove required `WorkDir` and legacy `ReportPath` request/result plumbing.
-2. Keep reusable domain normalization ordinary package code. Validation checks the
+Document production external-config defaults without forcibly overriding or

-   constructed values without silently fixing them.
-3. Inventory defaults in `load.go`: static defaults, per-map-entry/list-element
-   defaults, and inherited or presence-sensitive defaults. Retain named constants
-   in `defaults.go`. This inventory should guide code and concise comments, not
-   become a permanent parallel defaults document.
-4. Keep the current loader calling normalization explicitly before validation
-   during this preparatory stage. The ConfigKit resolver replaces that loading
-   choreography in Stage 4. Preserve family expansion as an explicit domain step.
 
-Acceptance: focused configuration tests prove normalization is deterministic and

-## Stage 3 — Replace composition-dependent effective projection
+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.
 
-Status: Complete — Introduced one typed safe projection for effective YAML,
+Reports are diagnostics, not a new correctness gate:
-semantic values, source paths, and the versioned v3 digest; removed composition
-parsing from those consumers and verified ordering, expansion, relocation,
-nil/empty, exact-integer, CLI diff, and semantic-resume behavior.
 
-Read: `internal/config/effective_pipeline.go`, `effective_digest.go`,
+- Bound reads of present reports using the existing named 16 MiB report limit;
-`pipeline_composition.go`, `internal/app/config_commands.go`, the config-diff

-implementation, and `docs/internal/configuration.md`.
+  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.

-2. Render this projection as deterministic YAML using the existing YAML encoder;
-   encoding output is not a replacement YAML loader. Produce semantic records
-   directly from the safe projection using standard JSON encoding/decoding with
-   number preservation if a plain value tree is useful. Do not reparse YAML or
-   reconstruct `compositionNode` trees to compare or hash effective values.
-3. Make show, diff values, and digest use that common projection. Mapping order is
-   immaterial; sequences remain atomic for diff; nil and empty remain distinct.
-   Exclude family declarations once expanded, all runtime metadata, profile names,
-   source locations, and raw credentials. Preserve logical Notarius path handling
-   so moving an equivalent bundle does not change its digest.
-4. Version the changed digest encoding explicitly using the package's digest

-## Stage 4 — Cut pipeline loading over to ConfigKit
+Generated invocation YAML becomes `audita.generated.v2`, recording actual

+a diagnostic invocation record, not an Audita configuration file.
 
-Status: Complete — Replaced pipeline composition with ConfigKit v0.1.1 imports,

-   and inherited defaults with `Resolution.Default`/`IsExplicit`; use recorded
-   normalization for transformations from Stage 2. Do not call old post-decode
-   zero-filling defaults. Remove `NormalizeConfig.UnmarshalYAML` and its private
-   presence bit. Include publication list-entry defaults, optional section
-   allocation, and trim's Scriptorium requirement in this conversion.
-3. Perform file-local semantic checks in the definition. Defer checks needing
-   canonical party expansion or campaign/session context to the existing explicit
-   resolution boundary; do not reject references to future concrete family members
-   merely because the campaign has not loaded yet. Run full checks after expansion.
-4. Replace pipeline composition and profile loaders. `configkit.imports` is the
-   only directive; no `composition` or `_configkit` alias is accepted. Pass profile
-   selection directly under the agreed convention; unselected overlays are not read.
-   `LoadPipelineProfilePair` may remain a thin pair of independent loads, with no
-   shared parse cache or paired source-snapshot promise.
-5. Adapt ConfigKit sources and metadata to Narratio's existing reporting records.
-   Translate paths structurally using public path APIs, not error-message parsing.
-   Preserve multiple contributing locations for composite/profile-owned mappings
-   and distinguish defaults/resolution from authored values.
-   Check artifact/family map-entry ownership for duplicate base declarations using
-   those locations; ignore synthetic defaults and allow the selected overlay.
-6. Attach runtime metadata only after load succeeds. Preserve root-relative runtime
-   path interpretation and capture logical paths before making them absolute.
-   Retain family declarations and original ConfigKit metadata for later expansion.
-7. Replace generic mechanism tests with a small integration set proving actual
-   Narratio wiring. Convert fixtures affected by this stage. Delete
-   `composition.go`, obsolete pipeline traversal/overlay/presence machinery, and
-   their redundant tests once the callers are migrated.
 
-Acceptance: a real root with imports and a testing overlay loads; duplicate claims
+## Stage 1: Adopt ConfigKit v0.4.0 and pipeline overlays
-fail with useful source attribution, including two base files contributing disjoint
-fields to one artifact or family key; base/default selection works; malformed

-still fail. Commands use the new pipeline loader with no format fallback. Update

-Unknown fields and disabled directives fail through ConfigKit. Focused config,

-prepare/extract, and application loading tests pass.
 
-## Stage 6 — Move secrets bootstrap before all configuration loads
+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.

-   caller CWD; otherwise choose `secrets/` beside the resolved root pipeline.
-   An explicitly empty flag is invalid. Missing conventional directories are
-   skipped; missing explicit directories and unreadable/invalid existing directories
-   fail. Use ConfigKit's selected-directory symlink behavior without custom rejection.
-3. Call `LoadSecretsDir` at most once per command before any ConfigKit load or
-   adapter creation, including both loads of config diff and remote session lookup.
-   Use invocation state, not a package-global `sync.Once`. A new command gets its
-   own bootstrap; library config loaders themselves never mutate the environment.
-4. Present safe bootstrap warnings/failures through stderr or the existing safe
-   diagnostic boundary, never into YAML show output. Preserve the partial report
-   on bootstrap failure. Do not add rollback or reinterpret ConfigKit file rules.
-5. Remove late bootstrap calls in object-store and runner composition, the custom
-   directory reader and permission platform files, `pipeline.secrets`, its defaults
-   and validators, and their obsolete tests. Convert affected fixtures immediately.

-## Stage 7 — Resolve typed credentials and protect all output boundaries
+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.

+## Stage 3: Migrate Notarius to credential lists
-   Reject old `_env` schema keys; remove their default-name and lookup helpers.
-   Convert maintained fixtures with synthetic environment setup where references
-   are present. Do not add credentials to unrelated local pipeline fixtures.
-2. Pass resolved S3 values to the SDK adapter's explicit static provider only when
-   the pair is configured. With neither, preserve its default provider chain.
-   Pass Audita the resolved value and safe reference name; deliver the value only
-   through the child environment's existing `AUDITA_LLM_API_KEY` override.
-   Do not re-read the environment for an explicitly resolved reference.
-3. Adapt every serialization, digest, source/diff output, diagnostic, generated
-   invocation config, manifest, and provenance caller to safe reference names.
-   Never YAML-marshal ConfigKit's opaque secret directly or call `Value()` in an
-   inspection path. Secret changes alone must not alter effective digests or
-   invalidate artifact evidence; reference-name changes may change provenance.
-4. Keep ConfigKit errors structured and safe. Domain validation messages must
-   avoid raw credential values; do not unwrap private parser errors or interpolate
-   whole trusted configuration structs into error messages.
-5. Preserve downstream tool ownership for Notarius/Scriptorium credentials that
-   Narratio does not configure. Do not add a parallel credential schema for them.

-4. Use the same finalized state as show/sources/diff and runtime configuration.
-   No session download, adapter initialization, manifest access, or workspace

+`docs/internal/adapters.md`, `docs/internal/stage-polish.md`, and pipeline examples.
+
+1. Complete current-behavior documentation as implementation lands. Configuration

+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

+   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,

+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

+# 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.

-## 7. Do not resolve unused base credentials when loading a profile
-
-Status: Resolved — P2
-
-Resolution: Upgraded to released ConfigKit v0.1.2 and replaced the extra base load
-with `Metadata.HistoricalPaths()` enumeration of declaration paths in the selected
-result. Ownership checks still inspect base-layer history for both ordinary
-artifacts and families, even when overlays remove them. Regression tests verify
-that a profile can replace an unset production credential with a resolvable testing
-reference or remove it with null. Existing hidden-duplicate and legitimate-override
-tests remain intact. No local dependency replacement or second composer is needed.
-
-Follow-up review: 2026-09-07 at `3ce1981`. The original six reproductions are
-addressed, but the fix for finding 3 introduces this regression.
-
-**Evidence:** `internal/config/pipeline_configkit.go:49-57` loads the base again
-without a profile to check duplicate base definitions. This calls the complete
-typed ConfigKit loader, including secret resolution, domain resolution, and
-validation—not just declaration ownership inspection. Consequently, loading a
-valid testing profile also requires credentials from the unselected base.
-
-**Reproduction:** In an otherwise valid base, set `audita.llm_api_key` to
-`NARRATIO_REVIEW_PROD_KEY`. In `profiles/testing.yml`, replace it with
-`NARRATIO_REVIEW_TEST_KEY`. Leave the production variable unset and supply only
-the testing variable with a synthetic value. `config validate --config <root>
---profile testing` fails with `secret.unset` at the base credential declaration.
-Supplying both variables makes it pass. A profile that instead sets
-`audita.llm_api_key: null` also fails when the unused production variable is
-unset. Both failures were reproduced through the current CLI.
-
-**Impact:** Operators cannot use an independent testing credential environment
-or remove a production credential requirement through a profile. Commands fail
-despite having all credentials required by their effective configuration. The
-extra full load also unnecessarily repeats configuration processing.
-
-**Required change:** Enforce unique base ownership without requiring the
-unselected base to succeed as a separately resolved runtime configuration.
-Inspect complete declaration history through ConfigKit's public metadata,
-including declarations displaced by overlays. If additional upstream metadata
-support is needed, address that explicitly rather than requiring unused secrets,
-suppressing arbitrary load failures, reparsing YAML, or restoring a second
-composer. Preserve the duplicate-definition protection added for finding 3.
-
-**Acceptance:** Add public-boundary regression tests for a profile replacing an
-unset production credential with an available testing credential, and for a
-profile removing that credential with null. Both must load successfully without
-the production variable. Retain failures for duplicate base ordinary/family
-definitions hidden by null overlays, along with legitimate profile override and
-profile-only definition coverage. Resolve secrets only for the selected effective
-configuration.
-
-## Follow-up verification
-
-After adopting ConfigKit v0.1.2 and completing finding 7, the full
-`scripts/check-release-candidate.sh v2.0.0` check passed: module hygiene,
-formatting/whitespace, uncached tests and race tests, vet, build, documentation,
-maintained examples, and Linux amd64/arm64 plus macOS arm64 release cross-builds.
-`go mod verify` also passed. The new credential regressions failed before the
-ownership-check fix and passed afterward. No local module replacements, release
-tags, or pushes were used.
-
-At `3ce1981`, `go test ./...`, `go test -race ./...`, `go vet ./...`, and
-`go build ./...` passed. The new finding was reproduced with a freshly built CLI,
-temporary configuration files, and synthetic credentials; no external adapters
-or cloud services were invoked. That review pass changed only this review record.
-
-## Original verification and scope
-
-The following checks passed at the reviewed commit:
-
-- `go test ./...`
-- `go test -race ./...`
-- `go vet ./...`
-- `go build ./...`

-
-The existing full suites include documentation and maintained-example checks.
-The findings above were additionally reproduced through a freshly built CLI with

+# 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
+  speaker authority; or
+- the manifest has only legacy aggregate transcribe state and cannot bind old
+  outputs to their source audio.
+
+Safe fix:
+
+- inspect the reported speaker and filesystem error, repair the prepared input
+  or canonical-output path when needed, then retry transcribe normally;
+- allow a legacy aggregate-only record to regenerate once; and
+- do not edit the manifest or copy an old JSON file into place as a substitute
+  for a successful checkpoint.

+## WhisperX model changed but transcription was reused
+
+Symptom:
+
+- WhisperX model weights, prompts, or private server configuration changed at
+  the same configured URL, but Narratio still considers speaker transcripts
+  current.
+
+Likely cause:
+
+- 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
+  only successfully checkpointed speakers.

+A canonical raw transcript left by the failed checkpoint is incidental and
+does not become reusable authority. Preserve the manifest and diagnostics if

+## 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
