-- Pin all action references to released tags (for example `@v1.0.0`).
+- **Always use full `https://` URLs** in `uses:` references for all vociferate actions (for example `uses: https://git.hrafn.xyz/aether/vociferate/prepare@v1.0.2`). This ensures correct action resolution on both GitHub and self-hosted Gitea instances. Never use shorthand coordinates like `aether/vociferate` without the full URL.
+- Pin all action references to released tags (for example `@v1.0.2`).
 - Keep all vociferate references on the same tag within a workflow.
-- In self-hosted runner environments (git.hrafn.xyz), use explicit `https://` action paths in `uses:` references and avoid shorthand owner/repo coordinates.
 - Use `prepare` action to update changelog/version and create release tags.
 - Use `publish` action to create/update release notes and assets from existing tags.
 - Do not mix alternate release actions unless a repository-local policy explicitly documents an override.

 ### Added
 
+- Added changelog gate validation to `decorate-pr` action for enforcing changelog updates on qualifying code changes.
+- Changelog gate modes: `strict` (fails job on violation) and `soft` (warns via PR comment).
+- Docs-only PR exemption with customizable glob patterns for documentation files.
+- PR label-based exemptions for changelog gate (example: `skip-changelog`).
+- Precise diff parsing: validates only added lines within the Unreleased section.
+- Gate decision outputs: `gate-passed`, `docs-only`, `unreleased-additions-count`, `gate-failure-reason` for reuse downstream.
+- Integrated remediation guidance in PR comments showing how to add changelog entries.
+
 ### Changed
 
+- Refactored `internal/vociferate` to use a constructor-backed service with injected filesystem, environment, and git dependencies while preserving the existing package-level API.
+- Hardened `prepare-release` validation to enforce formatting checks, module hygiene, `gosec`, and `govulncheck` before preparing a release.
+- Added matching local validation targets in `justfile` for formatting, module hygiene, tests, and security checks.
+- `decorate-pr` now reads Unreleased changelog content through the `vociferate` Go CLI instead of maintaining separate shell parsing logic in the composite action.
+- `publish` now extracts tagged release notes through the `vociferate` Go CLI instead of duplicating changelog section parsing in shell.
+- Composite actions now share a centralized `run-vociferate` orchestration flow, with binary-versus-source execution delegated through shared composite actions and single-use runtime/download logic folded back into `run-vociferate.binary`.
+- `run-vociferate` now contains both binary and source execution flows directly in a single action implementation, removing nested local action wrappers for better runner compatibility.
+
 ### Removed
 
 ### Fixed
 
+- Made `do-release` version resolution resilient to `workflow_call` input passing issues by adding a separate tag detection step that fetches and discovers the latest tag from origin as a fallback when `inputs.tag` is empty, enabling proper operation even when Gitea's workflow_call doesn't pass inputs through correctly.
+- Fixed version resolution in `do-release` workflow by moving version calculation before checkout, resolving from inputs/git tags, and always passing explicit version to `publish` action.
+- Made `publish` action version resolution more robust with clearer error messages when version input is missing and workflow is not running from a tag push.
+- Fixed `do-release` workflow to always checkout the resolved release tag, eliminating conditional checkout logic that could skip the checkout when called from `prepare-release` workflow.
+- Pinned `securego/gosec` and `golang/govulncheck-action` to concrete version tags (`v2.22.4` and `v1.0.4`) so self-hosted Gitea runners can resolve them via direct git clone without relying on the GitHub Actions floating-tag API.
+- Restored explicit gosec caching by storing a pinned `v2.22.4` binary under `${{ runner.temp }}/gosec-bin` with `actions/cache@v4`, so CI keeps fast security scans while still using the Go 1.26 toolchain from `setup-go`.
+- Replaced `securego/gosec` composite action with a direct `go install github.com/securego/gosec/v2/cmd/gosec@v2.22.4 && gosec ./...` run step so gosec uses the Go 1.26 toolchain installed by `setup-go` rather than the action's bundled Go 1.24 binary which ignores `GOTOOLCHAIN=auto`.
+- Fixed nested local composite-action references to use repository-local `./run-vociferate` paths so strict runners do not misparse parent-directory (`../`) action references as malformed remote coordinates.
+- Consolidated `run-vociferate` binary and source execution flows directly into the main `run-vociferate` action to avoid nested local-action path resolution issues on strict runners.
+- Hardened workflow module hygiene by retrying `go mod verify` after a module-cache refresh (`go clean -modcache` + `go mod download`) when runners report modified cached dependency directories.

+# Vociferate Standards Compliance Analysis
+
+**Date:** March 21, 2026  
+**Repository:** git.hrafn.xyz/aether/vociferate  
+**Analysis Scope:** Go codebase, CI workflows, and engineering practices
+
+---
+
+## Executive Summary
+
+The vociferate codebase demonstrates **solid fundamentals** in testing, error handling, and package organization but **lacks critical CI/CD workflow validation** steps documented in the project standards. The main gaps are:
+
+- ✅ **Strong:** Test structure (testify suites), coverage (80%+), error handling (proper wrapping)
+- ⚠️ **Acceptable:** Dependency injection patterns (functional options pattern used appropriately)
+- ❌ **Critical Gaps:** Missing `go fmt`, `go mod tidy/verify`, `gosec`, `govulncheck` in CI workflows
+
+---
+
+## 1. Testing Structure
+
+### ✅ Status: COMPLIANT
+
+**Findings:**
+
+- **Test file format:** Properly organized in `*_test.go` files
+  - [cmd/vociferate/main_test.go](cmd/vociferate/main_test.go)
+  - [internal/vociferate/vociferate_test.go](internal/vociferate/vociferate_test.go)
+  - [internal/vociferate/vociferate_internal_test.go](internal/vociferate/vociferate_internal_test.go)
+
+- **Testify suite usage:** ✅ Yes, properly implemented
+  - `PrepareSuite` in [vociferate_test.go](internal/vociferate/vociferate_test.go#L12) uses `suite.Suite`
+  - Tests use `require` assertions from testify
+  - Setup/teardown via `SetupTest()` method
+- **Coverage analysis:**
+  - **cmd/vociferate:** 84.6% ✅ (exceeds 80% target)
+  - **internal/vociferate:** 80.9% ✅ (meets 80% target)
+  - **Total:** Both packages meet or exceed target
+  - Coverage methodology: `go test -covermode=atomic -coverprofile=coverage.out ./...`
+
+**Compliance:** ✅ Full compliance with testing standards
+
+---
+
+## 2. Dependency Injection
+
+### ⚠️ Status: PARTIAL COMPLIANCE
+
+**Findings:**
+
+**What's Good:**
+
+- ✅ No global singletons or hidden state
+- ✅ Package state is minimal and functions are stateless
+- ✅ Functional options pattern used (`vociferate.Options` struct):
+  ```go
+  type Options struct {
+      VersionFile    string
+      VersionPattern string
+      Changelog      string
+  }
+  ```
+- ✅ Functions accept options explicitly (not constructor-injected, but appropriate for this use case)
+
+**What Needs Attention:**
+
+- ⚠️ **No explicit `New*` constructor functions** — This is acceptable for a utility library, but pattern not followed
+- ⚠️ **Global regex variables** (4 instances, should be const or lazy-initialized):
+
+  ```go
+  var releasedSectionRe = regexp.MustCompile(`(?m)^## \[(\d+\.\d+\.\d+)\] - `)
+  var linkedReleasedSectionRe = regexp.MustCompile(...)
+  var unreleasedHeadingRe = regexp.MustCompile(...)
+  var releaseHeadingRe = regexp.MustCompile(...)
+  var refLinkLineRe = regexp.MustCompile(...)
+  ```
+
+  - **Issue:** Mutable global state; should be const or initialized once
+  - **Low risk** for this codebase (single-use CLI), but violates best practices
+
+**Compliance:** ⚠️ Acceptable for library code; regex vars could be improved
+
+---
+
+## 3. Error Handling
+
+### ✅ Status: EXCELLENT
+
+**Findings:**
+
+- ✅ All errors wrapped with context using `fmt.Errorf("%w", err)`
+- ✅ Consistent error wrapping throughout codebase:
+  - [vociferate.go lines 68, 73, 81, 87, 104](internal/vociferate/vociferate.go#L68-L87)
+  - `"version must not be empty"` → `fmt.Errorf("version must not be empty")`
+  - `"compile version pattern: %w"` → wraps underlying error
+  - `"read version file: %w"` → proper context wrapping
+  - `"write changelog: %w"` → proper context wrapping
+
+- ✅ No log-and-return anti-pattern observed
+- ✅ Error propagation allows callers to decide handling
+
+**Examples of proper error handling:**
+
+```go
+// From updateVersionFile
+if err := os.ReadFile(path); err != nil {
+    if os.IsNotExist(err) {
+        return os.WriteFile(...)
+    }
+    return fmt.Errorf("read version file: %w", err)
+}
+
+// From resolveOptions
+versionExpr, err := regexp.Compile(pattern)
+if err != nil {
+    return resolvedOptions{}, fmt.Errorf("compile version pattern: %w", err)
+}
+```
+
+**Compliance:** ✅ Full compliance with error handling standards
+
+---
+
+## 4. Package Organization
+
+### ✅ Status: COMPLIANT
+
+**Findings:**
+
+- ✅ **Domain-driven structure:**
+  - `internal/vociferate/` — Core domain logic
+  - `cmd/vociferate/` — CLI entry point
+  - No layer-based top-level packages (no `service/`, `handler/`, `repository/`)
+
+- ✅ **Clear separation of concerns:**
+  - CLI parsing and execution in `cmd/vociferate/main.go`
+  - Domain logic in `internal/vociferate/vociferate.go`
+  - Tests colocated with implementations
+
+- ✅ **Version placeholder package** (empty, future-ready):
+  - `internal/vociferate/version/` — Prepared for versioning but not yet populated
+
+- ✅ **Minimal, focused code organization:**
+  - No unnecessary intermediate packages
+  - Clear domain boundaries
+
+**Compliance:** ✅ Full compliance with package organization standards
+
+---
+
+## 5. CI/CD Workflows
+
+### ✅ Status: COMPLIANT
+
+**Workflows analyzed:**
+
+- [push-validation.yml](.gitea/workflows/push-validation.yml)
+- [prepare-release.yml](.gitea/workflows/prepare-release.yml)
+- [do-release.yml](.gitea/workflows/do-release.yml)
+
+#### What's Implemented
+
+**push-validation.yml:**
+
+- ✅ Go 1.26.1 setup with `actions/setup-go@v5`
+- ✅ Caching enabled (`cache: true`, `cache-dependency-path: go.sum`)
+- ✅ Code formatting validation (`go fmt` check)
+- ✅ Module hygiene checks (`go mod tidy` and `go mod verify`)
+- ✅ Security analysis with `gosec`
+- ✅ Vulnerability scanning with `govulncheck`
+- ✅ Full unit test suite with coverage (`go test -covermode=atomic -coverprofile=coverage.out`)
+- ✅ Coverage badge publication
+- ✅ Release tag recommendation on `main` branch
+
+**prepare-release.yml:**
+
+- ✅ Go setup and caching
+- ✅ Tests run before release preparation
+- ✅ Version and changelog updates
+- ✅ Tag creation
+
+#### What's Fixed
+
+| Step                  | Documented Requirement                    | Push Validation | Status   |
+| --------------------- | ----------------------------------------- | --------------- | -------- |
+| **go fmt validation** | Required                                  | ✅ YES          | Enforced |
+| **go mod tidy**       | Required                                  | ✅ YES          | Enforced |
+| **go mod verify**     | Required                                  | ✅ YES          | Enforced |
+| **gosec**             | Required (`securego/gosec@v2`)            | ✅ YES          | Enforced |
+| **govulncheck**       | Required (`golang/govulncheck-action@v1`) | ✅ YES          | Enforced |
+
+**Implemented Actions (commit 7cb7b05):**
+
+```yaml
+# Now in push-validation.yml:
+- name: Validate formatting
+  run: test -z "$(gofmt -l .)"
+
+- name: Module hygiene
+  run: |
+    set -euo pipefail
+    go mod tidy
+    go mod verify
+
+- name: Run gosec security analysis
+  uses: securego/gosec@v2
+  with:
+    args: ./...
+
+- name: Run govulncheck
+  uses: golang/govulncheck-action@v1
+  with:
+    go-package: ./...
+    cache: true
+    cache-dependency-path: go.sum
+```
+
+**Note:** Changelog gate is a PR-level feature implemented in the `decorate-pr` action, not a push validation check.
+
+---
+
+## 6. Validation Sequence
+
+### ✅ Status: NOW FOLLOWING DOCUMENTED STANDARD
+
+**Documented sequence (from copilot-instructions.md):**
+
+1. ✅ Run `go fmt ./...` for code formatting
+2. ✅ **Validate formatting** — **NOW IMPLEMENTED**
+3. ✅ **Run `go mod tidy` and `go mod verify`** — **NOW IMPLEMENTED**
+4. ✅ Run focused package tests
+5. ✅ Run broader test suites
+6. ✅ **Run `gosec ./...`** — **NOW IMPLEMENTED**
+7. ✅ **Run `govulncheck ./...`** — **NOW IMPLEMENTED**
+8. ✅ Run full project validation (coverage checks)
+9. ✅ Verify coverage gates per module (target 80%)
+
+**Current workflow sequence (after commit 7cb7b05):**
+
+1. Setup Go environment with caching ✅
+2. Validate code formatting ✅
+3. Check module hygiene (tidy + verify) ✅
+4. Run security analysis (gosec) ✅
+5. Run vulnerability scanning (govulncheck) ✅
+6. Run full unit test suite with coverage ✅
+7. Publish coverage badge ✅
+8. (On main) Recommend next release tag ✅
+
+**Impact:** All security, formatting, and module checks now run in CI, preventing:
+
+- Inconsistent code formatting from merging ✅
+- Stale/incorrect `go.mod` from merging ✅
+- Known vulnerabilities from going undetected ✅
+
+---
+
+## 7. Additional Observations
+
+### Code Quality Improvements (commit 7cb7b05)
+
+**Regex Variables in `internal/vociferate/vociferate.go`:**
+
+- ✅ Grouped into `var (...)` block for clarity
+- ✅ Added clarifying comment about read-only nature
+- Maintains Go idioms while signaling immutability intent
+- No functional changes; improves code organization
+
+### Justfile (Local Automation)
+
+**Current state:** Aligned with CI baseline for local validation
+
+```bash
+go-build
+go-test
+validate-fmt
+validate-mod
+security
+validate
+```
+
+**Implemented locally (commit 383aad4):**
+
+- ✅ `validate-fmt` runs `go fmt ./...` and verifies `gofmt -l .` is clean
+- ✅ `validate-mod` runs `go mod tidy` and `go mod verify`
+- ✅ `security` runs `gosec ./...` and `govulncheck ./...`
+- ✅ `validate` composes formatting, module hygiene, tests, and security checks
+
+### Go Module Configuration
+
+✅ **go.mod** is properly configured:
+
+- Go 1.26 with toolchain 1.26.1
+- Dependencies: `github.com/stretchr/testify v1.10.0` (for test suites)
+- No extraneous dependencies
+
+### Code Formatting
+
+✅ **Code appears to follow Go conventions:**
+
+- Consistent naming (camelCase for exported names)
+- Proper error returns
+- Clear package documentation
+
+---
+
+## Recommendations (Priority Order)
+
+### ✅ COMPLETED (commit 7cb7b05)
+
+1. ✅ **`gosec` security scanning** — Now implemented in `push-validation.yml`
+2. ✅ **`govulncheck` vulnerability scanning** — Now implemented in `push-validation.yml`
+3. ✅ **`go fmt` validation** — Now implemented in `push-validation.yml`
+4. ✅ **Module hygiene checks** (`go mod tidy` + `go mod verify`) — Now implemented in `push-validation.yml`
+5. ✅ **Regex variable organization** — Grouped with clarifying comments in `vociferate.go`
+6. ✅ **DI service boundary** — `internal/vociferate` now uses a constructor-backed service with injected filesystem, environment, and git dependencies (commit 383aad4)
+7. ✅ **Local validation parity** — `justfile` now mirrors CI checks for format, modules, tests, and security (commit 383aad4)
+
+### 🟡 FUTURE (Lower Priority)
+
+8. **Implement changelog gate in PR workflows** — The `decorate-pr` action has changelog gate support; consider enabling `changelog-gate-mode: soft` in workflow if desired for future enhancement.

+
+## Conclusion
+
+**Current State (Updated):** The codebase now demonstrates strong engineering fundamentals in testing, error handling, structure, **and CI/CD validation**.
+
+✅ **All critical standards gaps have been addressed** across commits 7cb7b05 and 383aad4:
+
+- Security scanning (`gosec` + `govulncheck`) now enforced
+- Code formatting validation now required
+- Module hygiene checks (`go mod tidy`/`verify`) now enforced
+- Regex variable organization clarified
+- Dependency injection implemented through a constructor-backed service
+- Local `justfile` validation now mirrors CI checks
+
+**Validation Sequence:** The workflow now follows the documented 8-step validation sequence from copilot-instructions.md:
+
+1. Format validation
+2. Module hygiene
+3. Security analysis
+4. Vulnerability scanning
+5. Full test suite
+6. Coverage analysis
+
+**Effort Invested:**
+
+- CI/CD improvements: workflow hardening in `push-validation.yml` and `prepare-release.yml`
+- Code organization: injected service boundaries for filesystem, environment, and git access
+- Local automation: `justfile` validation parity for format, modules, tests, and security
+- **Primary commits:** 7cb7b05, 383aad4, 5c903c9

+#### Changelog Gate (Strict Mode)
+
+Enable changelog validation to enforce that code changes include `Unreleased` changelog entries. The gate fails the workflow in strict mode, or warns in soft mode:
+
+```yaml
+- name: Decorate pull request with changelog gate
+  if: github.event_name == 'pull_request'
+  uses: https://git.hrafn.xyz/aether/vociferate/decorate-pr@v1.0.2
+  with:
+    coverage-percentage: ${{ steps.coverage.outputs.total }}
+    badge-url: ${{ steps.coverage.outputs.badge-url }}
+    enable-changelog-gate: true
+    changelog-gate-mode: strict
+    changelog-gate-required-for: "code,behavior,security,workflow,tooling"
+    changelog-gate-allow-docs-only: true
+    changelog-gate-docs-globs: "docs/**,**.md,**.txt,**.rst"
+    changelog-gate-skip-labels: "skip-changelog"
+```
+
+The gate automatically:
+
+- Parses diffs to detect docs-only PRs (skips requirement for doc-only changes)
+- Counts `Unreleased` additions using section-aware parsing (ignores edits outside the section)
+- Checks PR labels for skip exemptions (for example, `skip-changelog`)
+- Outputs decision status and remediation guidance in the PR comment
+- Handles both strict (fail) and soft (warn) modes
+
+Decision outputs enable downstream workflow logic:
+
+```yaml
+- name: Decorate PR and check gate
+  id: decorate
+  if: github.event_name == 'pull_request'
+  uses: https://git.hrafn.xyz/aether/vociferate/decorate-pr@v1.0.2
+  with:
+    coverage-percentage: ${{ steps.coverage.outputs.total }}
+    badge-url: ${{ steps.coverage.outputs.badge-url }}
+    enable-changelog-gate: true
+    changelog-gate-mode: soft
+

+    echo "Gate passed: ${{ steps.decorate.outputs.gate-passed }}"
+    echo "Is docs-only PR: ${{ steps.decorate.outputs.docs-only }}"
+    echo "Unreleased additions: ${{ steps.decorate.outputs.unreleased-additions-count }}"
+    if [[ "${{ steps.decorate.outputs.gate-passed }}" == "false" ]]; then
+      echo "Gate failure reason: ${{ steps.decorate.outputs.gate-failure-reason }}"
+    fi
+```
+
 The action automatically finds existing vociferate comments by their marker and updates them instead of creating duplicates. This keeps PR timelines clean while keeping review information current.
