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

+# 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.

+
+Safe fix:

+- investigate unexpected links or special files as possible tampering; and
+- remove only the reported conflicting leaf or digest directory after
+  confirming it belongs to the reconstructible reference cache.

+## Notarius resume executes work instead of reusing it
+
+Symptom:
+
+- Narratio executes `extract`, and Notarius makes provider calls despite
+  `pipeline.notarius.resume: true`.
+
+Likely causes:
+
+- checkpoint recording is disabled in the Notarius configuration;
+- Notarius is using a nonpersistent or different checkpoint root;
+- transcript/reference bytes, reference paths, pipeline/profile content,
+  local-backend endpoint, selected lanes, or another checkpoint identity input
+  changed; or
+- Narratio extraction was forced, which deliberately omits `--resume`.
+
+Safe fix:
+
+- validate the deployed Notarius configuration and configure explicit
+  persistent chunk-plan and checkpoint roots;
+- inspect Notarius checkpoint decision reason codes for a legitimate cold miss;
+  and
+- retry without force only when reuse is intended.
+
+Remember that Narratio skipping a completed `extract` stage is separate from
+Notarius reusing work inside an extraction that does execute. Narratio does not
+read the Notarius configuration to infer checkpoint enablement.
