+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.
+
+## 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.

-repository-specific procedure must state all additional manual gates.
+ConfigKit provides one local release checker. Run it once against the final
+committed candidate using one maintained patch of the minimum supported Go line
+on Linux. It checks module hygiene, formatting and whitespace, the full offline
+suite with the race detector, static analysis, and CGO-disabled Linux amd64/arm64
+builds. Examples, documentation links, consumer fixtures, and package boundaries
+are covered by that suite, not separate repeated runs. Native package compilation
+is covered by the test run. A second toolchain is optional and non-gating.
 
-The required gates are:
+Commit the release note and associated changes before release validation. Record
+the exact validated commit; revalidate if the candidate changes. Do not require
+both pre-commit and post-commit full checker runs for unchanged content.
+Do not publish uncommitted or unvalidated content. Local check failures still
+block publication. Skipped test cases are reported, not separate human sign-off
+requirements.
 
-- dependency or module hygiene appropriate to the language and ecosystem;

-- production builds for every supported target that can be built in the
-  release environment;
-- 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;
-- review for unintended files, generated output, credentials, private data,
-  and unrelated changes; and
-- any additional security, compatibility, migration, packaging, or platform
-  checks required by the product.
-
-Unavailable tooling or an inapplicable check must be addressed explicitly in
-the adopted policy or release procedure; it must not disappear silently from
-the candidate gates.

+# ConfigKit v0.3.1
+
+This release fixes secrets-directory bootstrap when the directory contains Git
+metadata or other dot-prefixed entries.
+
+## Summary
+
+`LoadSecretsDir` now ignores dot-prefixed files, directories, and symlinks,
+including `.git`, `.gitignore`, and `.DS_Store`. These entries no longer prevent
+otherwise valid secrets from loading and are omitted from the bootstrap report.
+See the [bootstrap contract](../config.md#explicit-secrets-directory-bootstrap).
+
+## Compatibility
+
+This is a backward-compatible bug fix for previously rejected directory contents.
+There are no Go API signature changes or migrations for previously accepted
+inputs. Validation of non-hidden entries, existing-environment precedence, and
+the existing enumeration and content limits remain unchanged. Hidden entries
+still count toward the directory enumeration limit.
+
+The minimum Go version remains 1.25. Linux remains release-validated and macOS
+remains best-effort. The explicitly pinned YAML dependency remains
+`go.yaml.in/yaml/v4 v4.0.0-rc.6`; reassessment found no newer published version.
+Retaining this prerelease pin avoids unrelated parser changes in this patch.
+
+## Upgrade
+
+Update the module dependency and rebuild the consuming application:
+
+```sh
+go get gitea.maximumdirect.net/eric/ConfigKit@v0.3.1
+```
+
+No configuration migration is required. A secrets directory can retain its
+dot-prefixed metadata without treating those entries as secret candidates.
+
+## Changes
+
+- Filter hidden entries before filename and metadata validation and reporting.
+- Cover hidden-only and mixed directories, including Git metadata and a dangling
+  hidden symlink, with regression tests.
+- Update public API comments and the canonical bootstrap contract.
+- Stop tracking local codebase-memory tooling artifacts and ignore their directory.

+# ConfigKit v0.4.0
+
+This release renames selected configuration profiles to overlays, intentionally
+breaking the previous naming contract without compatibility aliases or fallback.
+
+## Summary
+
+Selected configuration now uses `Options.Overlay` and `overlays/<name>.yml`.
+Selection, merge rules, input precedence, and lifecycle behavior are unchanged.
+See the [selected-overlay contract](../config.md#selected-overlays).
+
+## Compatibility
+
+This is a breaking minor release before v1.0.0. Four surfaces change:
+
+- Go API: `Options.Profile` becomes `Options.Overlay`, `LayerProfile` becomes
+  `LayerOverlay`, and all seven `CodeProfile*` constants become `CodeOverlay*`.
+- Selected files: `profiles/<name>.yml` becomes `overlays/<name>.yml`; there is
+  no legacy-directory fallback.
+- Provenance: the layer string changes from `profile` to `overlay`.
+- Structured diagnostics: the `profile.*` code prefix becomes `overlay.*`.
+
+The old Go identifiers are removed. Application-owned concepts such as
+`ModelProfile` and `model_profile` are unchanged. Ordinary explicit imports from
+a directory named `profiles` remain valid base inputs.
+
+The minimum Go version remains 1.25. Linux remains release-validated and macOS
+remains best-effort. The YAML dependency remains pinned to
+`go.yaml.in/yaml/v4 v4.0.0-rc.6`; this release does not change parser dependencies.
+
+## Upgrade
+
+Update the dependency:
+
+```sh
+go get gitea.maximumdirect.net/eric/ConfigKit@v0.4.0
+```
+
+Rename the affected Go identifiers, move selected files into `overlays/`, update
+any handling of provenance-layer and diagnostic-code strings, and rebuild.
+The maintained example helper is now `LoadNarratioOverlay` rather than
+`LoadNarratioProfile`. Application CLI flag names remain application-owned;
+ConfigKit does not require renaming domain-specific profile concepts.
+See the [migration guide](../consumers/README.md#selected-overlay-migration).
+
+## Changes
+
+- Rename the selected feature consistently across the public facade, internal
+  engine, diagnostics, source labels, examples, and current documentation.
+- Add regression coverage for the new directory, absence of legacy fallback,
+  public values, explanations, and preservation of application profile fields.
+- Align contributor policies with the current shared standard.
+- Simplify release validation to one local minimum-toolchain check. CI is not a
+  release gate; successful publication of the intended tag completes the
+  source-only release. See the [release procedure](../release.md).
+- Retire completed overlay and release-workflow planning documents to Git history.
