docs: prepare CHANGELOG for v0.11.0 release

Add release notes extraction from CHANGELOG for publishing:

- Create ChangelogParser class to extract version sections from CHANGELOG
- Support multiple output formats: markdown, plain text, HTML
- Add 'release notes VERSION' CLI command to extract notes
- Auto-detect latest version if not specified
- Support piping to gh/gitea release commands
- Save to file with --output option
- Plain text format removes markdown formatting
- HTML format converts markdown to HTML

This streamlines creating release notes for GitHub/Gitea releases
by extracting CHANGELOG content automatically.

Usage:
  release notes 0.10.0                    # Extract markdown notes
  release notes                           # Latest version
  release notes 0.10.0 --format plain    # Plain text
  release notes 0.10.0 -o notes.md       # Save to file
  release notes 0.10.0 | gh release create v0.10.0 -F -

 - Updated all file references and paths to point to single source of truth in capabilities/testdrive-jsui/js/controls/ directory
 
 ### Fixed
+- **Version Detection Issue**: Fixed `markitect --version` returning "unknown" instead of actual version
+  - Added `git_describe_command` to setuptools-scm configuration to filter version tags correctly
+  - Configured git describe to use `--match 'v*'` pattern to ignore non-version tags
+  - Version detection now works correctly with development versions (e.g., 0.9.1.dev76)
+- **Missing v0.9.0 Git Tag**: Retroactively created v0.9.0 annotated tag on commit b9c1b90 from 2025-11-14
+  - Maintains version history integrity (CHANGELOG documented v0.9.0 but tag was missing)
+  - Enables proper version progression to v0.10.0
 - Duplicate file structure issue by eliminating duplicate control files and consolidating to capabilities/ directory
 - Contents panel scrollbar behavior - moved overflow-y: auto to correct container level so scrollbar only spans content area when panel reaches max-height

+**Smell**: Different filename conventions od conflicting concepts, unclear guideance
+**Hunch**: Ideas to explore that need consideration if useful and in scope
+**Hickups**: Notes on inefficient or roundtripping implementation to analyse later

 ### Example Issue Creation During Development:
 **Scenario**: While implementing CLI commands, discover that error messages could be improved
 **Action**: Create issue "Enhance CLI error messages with user-friendly formatting and suggestions"
 **Result**: Continue with current CLI implementation, address error enhancement in future session
 
+Generate issues for relevantly expensive or risky stuff and in direct feedback with developers.

+## Document Validation (Semantic)
+
+### Validate Documents Against Schemas
+
+Beyond validating schema structure, MarkiTect can validate actual markdown documents against schemas, checking both structural (AST) and semantic (x-markitect extensions) aspects.
+
+**Validate a document:**
+
+```bash
+# Full validation (structural + semantic)
+markitect validate my-document.md --schema manpage-schema-v1.0.md
+
+# Only structural validation (classic mode)
+markitect validate my-document.md --schema schema.json --no-semantic
+
+# With external link checking (may be slow)
+markitect validate my-document.md --schema manpage-schema-v1.0.md --check-links
+
+# Strict mode (warnings become errors)
+markitect validate my-document.md --schema manpage-schema-v1.0.md --strict
+```
+
+### What is Validated
+
+**Structural Validation** (always enabled):
+- Document AST structure matches JSON Schema properties
+- Heading counts, paragraph counts, code block counts
+- Element types and nesting
+
+**Semantic Validation** (enabled by default with --semantic):
+- **Section Classifications**: Checks that documents have required sections, don't have improper sections
+  - REQUIRED sections must be present (ERROR if missing)
+  - RECOMMENDED sections should be present (WARNING if missing)
+  - IMPROPER sections must not be present (ERROR if found)
+  - DISCOURAGED sections should not be present (WARNING if found)
+  - OPTIONAL sections may or may not be present (no check)

+
+---
+
+## 💡 Key Features
+
+1. **Markdown-First Schema Format**
+   - Human-readable schema files
+   - Embedded JSON with rich documentation
+   - Version history in same file
+   - Self-documenting schemas
+
+2. **Section Classification System**
+   - 5-level system: required/recommended/optional/discouraged/improper
+   - Alternative section names support
+   - Flexible enforcement with warnings vs. errors
+
+3. **Content Control**
+   - Regex pattern validation (required/forbidden/discouraged)
+   - Quality metrics (word counts, sentence counts)
+   - Content instructions for guidance
+   - Link validation (internal/external/email)
+
+4. **Schema Refinement Tools**
+   - Automated rigidity detection
+   - Safe automatic refinement
+   - Interactive approval mode
+   - Rigidity scoring
+
+5. **Production Features**
+   - Backward compatible (--no-semantic flag)
+   - CI/CD integration (exit codes, strict mode)
+   - Performance optimized (fast by default, opt-in for slow operations)
+   - Comprehensive error reporting
+
+---
+
+## 🔧 Technical Highlights
+
+### Bugs Fixed
+
+1. **Markdown Schema Support**
+   - **Issue**: validate and generate-stub commands only supported JSON schemas
+   - **Fix**: Added load_schema_from_path() to handle both .json and .md files
+   - **Impact**: All schema commands now work with markdown schemas
+
+2. **AST Heading Extraction**
+   - **Issue**: SemanticValidator couldn't extract headings from document AST
+   - **Fix**: Created DocumentWrapper class to parse AST and provide get_headings_by_level()
+   - **Impact**: Section validation now works correctly
+
+3. **Content Control Key Mismatch**
+   - **Issue**: Content control keys must be lowercase even when section names are title case
+   - **Fix**: Updated ADR schema to use lowercase keys
+   - **Impact**: Content validation now follows established pattern
+
+### Known Limitations
+
+1. **Content Extraction**: ContentValidator shows "0 words" for all sections
+   - Cause: ContentValidator needs updates to work with DocumentWrapper
+   - Impact: Content quality metrics not working yet
+   - Status: Known limitation, can be fixed in future update
+
+2. **Stub Generation**: generate-stub doesn't use x-markitect-sections
+   - Cause: StubGenerator uses structural schema, not x-markitect extensions
+   - Impact: Generated stubs have generic sections instead of schema-specific ones
+   - Status: Future enhancement
+
+---
+
+## 🚀 Implementation Path
+
+The original 5-phase workplan was executed across **three major efforts**:
+
+1. **Schema-of-Schemas** (260105)
+   - Phases 1-2: Schema format and refinement tools
+   - 787-line workplan implemented over multiple sessions
+   - Created foundation for all schema features
+
+2. **Semantic Document Validation** (260106)
+   - Phase 3: Validation engine
+   - Built modular validator architecture
+   - Integrated into validate command
+
+3. **Schema Evolution Closure** (260106)
+   - Created ADR schema as showcase
+   - Fixed markdown schema support bugs
+   - Documented completion status
+
+---
+
+## 📈 What Was Deferred
+
+**Phase 4: Blueprint System** - Deferred to future roadmap
+- Reason: Requires 15-20 sessions, represents major feature expansion
+- Scope: Multi-schema composition, blueprint registry, conflict resolution
+- Alternative: Current template generation (StubGenerator) sufficient for now
+- Future: Can be implemented when user demand increases
+
+**CI/CD Integration Templates** (Phase 5) - Deferred to future roadmap
+- Reason: Can be added as documentation without code changes
+- Scope: Pre-commit hooks, GitHub Actions examples
+- Impact: Not blocking for core functionality
+- Future: Easy to add as examples when needed
+
+---
+
+## 🎓 Lessons Learned
+
+1. **Iterative Implementation**: Breaking large features into smaller sessions worked well
+2. **Test-Driven Development**: 90%+ test coverage prevented regressions
+3. **Documentation-First**: Writing docs early helped clarify requirements
+4. **Pragmatic Scoping**: Deferring Phase 4 was the right call - delivered value faster
+5. **Bug Discovery**: Real-world usage (ADR schema) revealed markdown support bugs

+# Plan: Schema System Enhancement - Semantic Document Validation
+
+## Overview
+
+The schema management system has **complete schema structure analysis tools** (schema-analyze, schema-refine) and **structural AST validation** (markitect validate), but is missing **semantic validation capabilities**. This plan enhances validation to check sections, content patterns, and quality metrics defined in x-markitect extensions.
+
+## Current State Assessment
+
+### ✅ Already Implemented
+- **schema-analyze**: Detects rigid constraints, calculates rigidity score (markitect/schema_analyzer.py)
+- **schema-refine**: Automatically loosens rigid constraints (markitect/schema_refiner.py)
+- **markitect validate**: Validates AST structure against JSON schemas (cli.py:1493-1600)
+  - Checks headings, paragraphs, code_blocks counts match schema
+  - Validates document structure against JSON Schema properties
+  - Does NOT check x-markitect-sections classifications
+  - Does NOT validate x-markitect-content-control patterns
+- **X-Markitect Extensions**: Full system with sections, content-control, metadata
+- **Metaschema Validation**: Validates schema structure and extensions
+- **4 Production Schemas**: manpage, API docs, terminology, schema-schema
+- **Comprehensive Documentation**: User guides, specifications, tests (97 tests passing)
+
+### ❌ Missing Capabilities (Semantic Validation)
+1. **Section Classification Enforcement**: required/recommended/optional/discouraged/improper not checked
+2. **Content Pattern Validation**: required_patterns, forbidden_patterns not matched
+3. **Quality Metrics Validation**: min_words, max_words, min_sentences not enforced
+4. **Link Validation**: Internal/external link checking not implemented
+5. **Content Instructions**: content_instruction fields defined but not validated
+
+## What We Have vs What We Need
+
+**Current `markitect validate`** (Structural):
+```bash
+markitect validate doc.md --schema schema.json
+# ✅ Checks: headings.level_2 has 5-30 items
+# ✅ Checks: paragraphs has 10-500 items
+# ✅ Checks: code_blocks has 1-50 items
+# ❌ Does NOT check: SYNOPSIS section present (required)
+# ❌ Does NOT check: INTERNAL_NOTES absent (improper)
+# ❌ Does NOT check: Synopsis contains bold command name
+# ❌ Does NOT check: Description has min 50 words
+```
+
+**Enhanced `markitect validate`** (Structural + Semantic):
+```bash
+markitect validate doc.md --schema manpage-schema-v1.0.md
+# ✅ Checks: AST structure (existing)
+# ✅ NEW: SYNOPSIS section present (required)
+# ✅ NEW: INTERNAL_NOTES not present (improper)
+# ✅ NEW: Synopsis contains **command** pattern
+# ✅ NEW: Description has 50+ words
+# ✅ NEW: No forbidden TODO patterns
+```
+
+## Implementation Plan
+
+### Phase 1: Core Semantic Validator
+
+**Goal**: Create semantic validator to complement existing structural validation
+
+**New Module**: `markitect/semantic_validator.py`
+
+**Key Components**:
+
+```python
+class SemanticValidator:
+    """Validates markdown documents against x-markitect extensions.
+
+    Complements existing SchemaValidator which handles structural AST validation.
+    This validator checks semantic aspects defined in x-markitect-* extensions.
+    """
+
+    def __init__(self, schema_path: str):
+        # Load schema (supports .md schemas with embedded JSON)
+        self.schema = load_schema_with_extensions(schema_path)
+
+        # Initialize sub-validators
+        self.section_validator = SectionValidator(self.schema)
+        self.content_validator = ContentValidator(self.schema)
+        self.link_validator = LinkValidator(self.schema)
+
+    def validate(self, document_path: str, check_links: bool = False) -> SemanticValidationReport:
+        """Main semantic validation entry point."""
+        doc = parse_markdown_document(document_path)
+
+        results = {
+            'sections': self.section_validator.check(doc),
+            'content': self.content_validator.check(doc)
+        }
+
+        if check_links:
+            results['links'] = self.link_validator.check(doc)
+
+        return SemanticValidationReport(results)
+```
+
+**Features**:
+- Load schema from registry or filesystem
+- Parse markdown document into AST
+- Validate sections against x-markitect-sections classifications
+- Check content against x-markitect-content-control patterns
+- Validate links if enabled
+- Generate detailed report with line numbers
+
+### Phase 2: Section Presence Validator
+
+**New Module**: `markitect/section_validator.py`
+
+**Validation Rules**:
+
+```python
+class SectionValidator:
+    """Validates section presence and classification compliance."""
+
+    def check(self, document: MarkdownDocument) -> SectionValidationResult:
+        sections_spec = self.schema.get('x-markitect-sections', {})
+        doc_sections = document.get_headings_by_level(2)
+
+        issues = []
+
+        # Check REQUIRED sections
+        for section_name, spec in sections_spec.items():
+            if spec['classification'] == 'required':
+                if section_name not in doc_sections:
+                    issues.append(SectionMissing(
+                        section=section_name,
+                        severity='ERROR',
+                        message=spec.get('error_message', f'{section_name} is required')
+                    ))
+
+        # Check IMPROPER sections (must not exist)
+        for section_name, spec in sections_spec.items():
+            if spec['classification'] == 'improper':
+                if section_name in doc_sections:
+                    issues.append(SectionImproper(
+                        section=section_name,
+                        severity='ERROR',
+                        message=spec.get('error_message', f'{section_name} must not appear')
+                    ))
+
+        # Check RECOMMENDED sections (warnings)
+        for section_name, spec in sections_spec.items():
+            if spec['classification'] == 'recommended':
+                if section_name not in doc_sections:
+                    issues.append(SectionMissing(
+                        section=section_name,
+                        severity='WARNING',
+                        message=spec.get('warning_if_missing', f'{section_name} is recommended')
+                    ))
+
+        return SectionValidationResult(issues)
+```
+
+**Section Classification Enforcement**:
+- REQUIRED → ERROR if missing
+- RECOMMENDED → WARNING if missing
+- OPTIONAL → No check
+- DISCOURAGED → WARNING if present
+- IMPROPER → ERROR if present
+
+### Phase 3: Content Pattern Validator
+
+**New Module**: `markitect/content_validator.py`
+
+**Pattern Matching**:
+
+```python
+class ContentValidator:
+    """Validates content against x-markitect-content-control rules."""
+
+    def check(self, document: MarkdownDocument) -> ContentValidationResult:
+        content_rules = self.schema.get('x-markitect-content-control', {})
+        issues = []
+
+        for section_key, rules in content_rules.items():
+            section = document.get_section(section_key.upper())
+            if not section:
+                continue  # Section validator handles missing sections
+
+            # Check required patterns
+            for pattern in rules.get('required_patterns', []):
+                if not re.search(pattern, section.content):
+                    issues.append(PatternMissing(
+                        section=section.name,
+                        pattern=pattern,
+                        severity='ERROR'
+                    ))
+
+            # Check forbidden patterns
+            for pattern in rules.get('forbidden_patterns', []):
+                if re.search(pattern, section.content):
+                    issues.append(ForbiddenPattern(
+                        section=section.name,
+                        pattern=pattern,
+                        severity='ERROR',
+                        matched_text=match.group(0)
+                    ))
+
+            # Check content quality
+            quality = rules.get('content_quality', {})
+            word_count = len(section.content.split())
+
+            if 'min_words' in quality and word_count < quality['min_words']:
+                issues.append(ContentTooShort(
+                    section=section.name,
+                    actual=word_count,
+                    required=quality['min_words'],
+                    severity='WARNING'
+                ))
+
+            if 'max_words' in quality and word_count > quality['max_words']:
+                issues.append(ContentTooLong(
+                    section=section.name,

+                ))
+
+        return ContentValidationResult(issues)
+```
+
+**Content Rules Checked**:
+- Required patterns (regex matches)
+- Discouraged patterns (warnings)
+- Forbidden patterns (errors)
+- Word count ranges (min/max)
+- Sentence counts (if specified)
+
+### Phase 4: Link Validator
+
+**New Module**: `markitect/link_validator.py`
+
+**Link Checking**:
+
+```python
+class LinkValidator:
+    """Validates links according to x-markitect-content-control.link_validation."""
+
+    def check(self, document: MarkdownDocument) -> LinkValidationResult:
+        link_config = self.schema.get('x-markitect-content-control', {}).get('link_validation', {})
+
+        if not any(link_config.values()):
+            return LinkValidationResult([])  # No link validation configured
+
+        links = document.extract_links()
+        issues = []
+
+        for link in links:
+            # Check internal links
+            if link.is_internal() and link_config.get('check_internal', False):
+                target = document.resolve_internal_link(link.target)
+                if not target:

+                        severity='ERROR'
+                    ))
+

+            if link.is_external() and link_config.get('check_external', False):
+                # HTTP HEAD request with timeout
+                if not self._check_url_exists(link.target):
+                    issues.append(BrokenExternalLink(
+                        link=link.target,
+                        line=link.line_number,
+                        severity='WARNING'  # External links are warnings
+                    ))
+
+            # Check fragments
+            if link.has_fragment() and not link_config.get('allow_fragments', True):

+                ))
+
+        return LinkValidationResult(issues)
+```
+
+**Link Types Validated**:
+- Internal links (to other sections/documents)
+- External links (HTTP/HTTPS URLs)
+- Fragment identifiers (#section-name)
+- Email links (mailto:)
+
+### Phase 5: CLI Integration
+
+**Enhance Existing Command**: `markitect validate` (cli.py:1493-1600)
+
+**New Options to Add**:
+
+```python

+5. Default to semantic=True for new markdown schemas with extensions

+```
+
+## Implementation Phases

+### Phase 1 (Core - 1 session)
+- DocumentValidator class
+- Basic section validation
+- CLI validate command
+- Simple text output format
+
+### Phase 2 (Content - 1 session)
+- ContentValidator with pattern matching
+- Word count validation
+- Quality metrics checking
+- Enhanced reporting
+
+### Phase 3 (Links - 1 session)
+- LinkValidator with internal link checking
+- Optional external link validation
+- Fragment validation
+- Performance optimization (caching)
+
+### Phase 4 (Polish - 1 session)
+- Batch validation support
+- JSON/table output formats
+- Integration tests
+- Documentation updates
+
+## Critical Files
+
+**New Files**:
+- `markitect/semantic_validator.py` - Main semantic validator (complements existing SchemaValidator)
+- `markitect/validators/section_validator.py` - Section classification enforcement
+- `markitect/validators/content_validator.py` - Content pattern matching and quality
+- `markitect/validators/link_validator.py` - Link validation
+- `markitect/validators/__init__.py` - Validators package
+- `tests/test_semantic_validator.py` - Semantic validator tests
+- `tests/validators/test_section_validator.py` - Section validator tests
+- `tests/validators/test_content_validator.py` - Content validator tests
+- `tests/validators/test_link_validator.py` - Link validator tests
+
+**Modified Files**:
+- `markitect/cli.py` (lines 1493-1600) - Enhance validate command with semantic validation
+- `markitect/schema_loader.py` - May need utility to extract x-markitect extensions
+- `docs/SCHEMA_MANAGEMENT_GUIDE.md` - Add semantic validation section
+- `examples/manpages/README.md` - Add validation examples
+- `examples/terminology/README.md` - Add validation examples
+
+**Reference Files** (unchanged, used for integration):
+- `markitect/validator.py` - Existing SchemaValidator for structural validation
+- `markitect/schema_analyzer.py` - Reference for schema extension parsing
+
+## Design Decisions
+
+### 1. Markdown Parsing
+**Decision**: Use existing markdown parser from markitect core
+**Rationale**: Already handles frontmatter, sections, AST generation
+
+### 2. Link Validation Default
+**Decision**: Internal links checked by default, external links opt-in
+**Rationale**: External link checking is slow (network requests), internal is fast
+
+### 3. Severity Levels
+**Decision**: ERROR (required violations), WARNING (recommended violations), INFO (suggestions)
+**Rationale**: Matches schema classification system semantics
+
+### 4. Exit Codes
+**Decision**: 0=success, 1=validation failed, 2=system error
+**Rationale**: Standard CLI conventions for CI/CD integration
+
+### 5. Pattern Syntax
+**Decision**: Use Python regex patterns directly
+**Rationale**: Schemas already use regex strings, no need for new syntax
+
+## Testing Strategy
+
+### Unit Tests
+- SectionValidator: Test all classification types
+- ContentValidator: Test pattern matching, word counts
+- LinkValidator: Test internal/external link checking
+- ValidationReport: Test formatting and aggregation
+
+### Integration Tests
+- Validate real manpage documents against manpage schema
+- Validate terminology documents against terminology schema
+- Test batch validation across multiple documents
+- Test CLI output formats
+
+### Edge Cases
+- Documents with no schema sections defined
+- Schemas with no content-control rules
+- Empty documents
+- Documents with malformed links
+- Unicode in patterns and content
+
+## User Workflows
+
+### Workflow 1: Validate Single Document
+```bash
+# Validate a manpage
+markitect validate my-command.1.md --schema manpage-schema-v1.0.md
+
+# With link checking
+markitect validate my-command.1.md --schema 1 --check-links
+```
+
+### Workflow 2: CI/CD Integration
+```bash
+#!/bin/bash
+# Validate all manpages in CI
+if ! markitect validate-batch docs/man/ --schema 1 --strict; then
+    echo "Manpage validation failed!"
+    exit 1
+fi
+```
+
+### Workflow 3: Pre-commit Hook
+```bash
+# .git/hooks/pre-commit
+files=$(git diff --cached --name-only --diff-filter=ACM | grep '\.1\.md$')
+for file in $files; do
+    if ! markitect validate "$file" --schema manpage-schema-v1.0.md; then
+        echo "Fix validation errors before committing"
+        exit 1
+    fi
+done
+```
+
+### Workflow 4: Interactive Editing
+```bash
+# Validate while editing
+watch -n 2 'markitect validate draft.md --schema api-documentation-schema-v1.0.md'
+```
+
+## Success Metrics
+
+1. **Core Functionality**: Can validate documents against all 4 production schemas
+2. **Classification Enforcement**: Required/improper sections properly checked
+3. **Pattern Matching**: Content patterns validated with regex
+4. **Performance**: Validate 100 documents in < 5 seconds (without link checking)
+5. **Test Coverage**: > 90% coverage for new validator modules
+6. **Documentation**: Complete examples for each schema type
+
+## Future Enhancements (Out of Scope)
+
+- Auto-fixing document validation errors
+- Suggestion engine for missing content
+- Readability scoring with specific algorithms
+- Image validation (size, format, accessibility)
+- Schema evolution analysis (breaking changes between versions)
+- Document-to-schema generation (inverse of current flow)
+

+
+# Architecture Decision Record Schema v1.0
+
+## Overview
+
+This schema defines the structure and validation rules for Architecture Decision Records (ADRs) in MarkiTect's markdown format. It includes comprehensive section classification, content control patterns, and quality guidelines to ensure consistent, high-quality architectural documentation.
+
+Architecture Decision Records are documents that capture important architectural decisions along with their context and consequences. This schema ensures ADRs follow a standardized structure that promotes thorough decision documentation and facilitates future reference.
+
+## Features
+
+- **Section Classification System**: Categorizes ADR sections as required, recommended, optional, discouraged, or improper
+- **Content Control**: Validates content patterns, quality metrics, and structural requirements
+- **Flexible Section Names**: Supports alternative section names (e.g., "OPTIONS CONSIDERED" as alternative to "ALTERNATIVES CONSIDERED")
+- **Quality Enforcement**: Minimum/maximum content requirements for key sections
+- **Decision Matrix Support**: Validates tabular comparison of alternatives
+- **Date and Status Validation**: Enforces proper date formats and status indicators
+
+## Section Classifications
+
+### Required Sections
+
+- **STATUS**: Current state of the decision (Proposed, Accepted, Deprecated, Superseded) with date
+- **CONTEXT**: Background information explaining why this decision is needed
+  - **Requirements** (recommended subsection): Specific needs driving the decision
+  - **Problem Statement** (recommended subsection): Clear articulation of the problem
+- **DECISION**: Clear statement of what was decided, starting with "We will"
+- **ALTERNATIVES CONSIDERED**: Options that were evaluated before making the decision
+- **RATIONALE**: Explanation of why this decision was made
+  - Must include "Why [Selected]?" subsection
+  - Must include "Why Not [Alternative]?" subsections for rejected options
+- **CONSEQUENCES**: Impact of the decision
+  - **Positive** (required subsection): Benefits and advantages
+  - **Negative** (required subsection): Drawbacks and limitations
+  - **Mitigation Strategies** (recommended subsection): How to address negatives
+- **APPROVAL**: Decision approval metadata (who, when, next review)
+
+### Recommended Sections
+
+- **DECISION MATRIX**: Tabular comparison of alternatives with criteria
+- **IMPLEMENTATION DETAILS**: Technical specifications and code examples
+
+### Optional Sections
+
+- **FUTURE CONSIDERATIONS**: Potential enhancements and evolution paths
+- **REFERENCES**: External documentation, specifications, and resources
+
+### Discouraged Sections
+
+- **DRAFT NOTES**: Development notes (should be removed before acceptance)
+- **OPEN QUESTIONS**: Unresolved items (should be resolved before acceptance)
+
+### Improper Sections
+
+- **INTERNAL_DISCUSSIONS**: Internal team debates (must not appear in published ADRs)
+- **TODO**: Development tasks (remove before publication)
+- **TEMPORARY**: Temporary content markers (remove before publication)
+
+## Usage
+
+### Validating an ADR
+
+```bash
+markitect validate ADR-001-my-decision.md --schema adr-schema-v1.0
+```
+
+### Common Validation Errors
+
+1. **Missing Required Sections**: Ensure STATUS, CONTEXT, DECISION, ALTERNATIVES CONSIDERED, RATIONALE, CONSEQUENCES, and APPROVAL are present
+2. **Missing "We will" Statement**: DECISION must contain a bold statement starting with "We will"
+3. **Incomplete Rationale**: Must include both "Why [Selected]?" and "Why Not [Alternative]?" subsections
+4. **Missing Consequence Subsections**: Both Positive and Negative subsections required
+5. **Improper Status Format**: STATUS must follow pattern `**[Status]** - YYYY-MM-DD`
+
+## Content Quality Guidelines
+
+### STATUS Section
+
+- Format: `**[Status]** - YYYY-MM-DD`
+- Valid statuses: Proposed, Accepted, Deprecated, Superseded
+- Example: `**Accepted** - 2025-11-10`
+- Keep concise (3-20 words)
+
+### CONTEXT Section
+
+- Explain the background and circumstances
+- Describe the business or technical drivers
+- Include Requirements subsection for specific needs
+- Include Problem Statement subsection for clear problem articulation
+- Minimum 100 words for comprehensive context
+
+### DECISION Section
+
+- Must start with bold statement: `**We will [decision]**`
+- Be specific and actionable
+- Avoid ambiguity
+- Example: `**We will use IndexedDB for client-side debug log storage**`
+
+### ALTERNATIVES CONSIDERED Section
+
+- List all options evaluated (minimum 2)
+- Include technology/implementation details for each
+- Provide sufficient detail for future reviewers
+- Minimum 150 words total
+
+### DECISION MATRIX Section
+
+- Use markdown table format
+- Include evaluation criteria as columns
+- Use emoji indicators: ✅ (positive), ⚠️ (caution), ❌ (negative)
+- Compare all alternatives systematically
+
+### RATIONALE Section
+
+- Include `### Why [Selected Option]?` subsection explaining the choice
+- Include `### Why Not [Alternative]?` subsection(s) for each rejected option
+- Provide technical and business justifications
+- Minimum 100 words total
+
+### IMPLEMENTATION DETAILS Section
+
+- Include code examples with syntax highlighting
+- Specify technical configurations
+- Document integration points
+- Provide sufficient detail for implementation
+
+### CONSEQUENCES Section
+
+- **Positive** subsection: List benefits and advantages
+- **Negative** subsection: List drawbacks and limitations
+- **Mitigation Strategies** subsection: Address how negatives will be handled
+- Minimum 50 words total
+- Be honest about trade-offs
+
+### APPROVAL Section
+
+- Include: Decided by, Date, Context, Next Review
+- Use ISO 8601 date format (YYYY-MM-DD)
+- Specify review period for periodic reassessment
+
+## Filename Convention
+
+ADR files must follow this naming pattern:
+
+```
+ADR-[0-9]{3}-[kebab-case-title].md
+```
+
+Examples:
+- `ADR-001-client-side-debug-storage.md`
+- `ADR-002-robustness-principle-for-production-use.md`

+## Usage Examples
+
+### Valid Changelog Structure
+
+```markdown
+# Changelog
+
+All notable changes to this project will be documented in this file.
+
+The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/),
+and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
+
+## [Unreleased]
+
+## [1.0.0] - 2026-01-06
+
+### Added
+- New feature A
+- New feature B
+
+### Fixed
+- Bug fix for issue #123
+```
+
+### Validation Command
+
+```bash
+# Ingest schema
+markitect schema-ingest markitect/schemas/changelog-schema-v1.0.md
+
+# Validate changelog
+markitect validate CHANGELOG.md --schema changelog-schema-v1.0.md --semantic
+```
+
+## Validation Checks
+
+### Required Elements
+- ✅ Title: Must be "# Changelog"
+- ✅ Unreleased section: `## [Unreleased]` must be present
+- ✅ Version format: `## [X.Y.Z] - YYYY-MM-DD` for all releases
+
+### Recommended Elements
+- ⭐ Introduction paragraph referencing Keep a Changelog
+- ⭐ Semantic Versioning reference
+- ⭐ At least one change type subsection per version
+
+### Content Patterns
+- Version sections use semantic versioning (MAJOR.MINOR.PATCH)
+- Dates in ISO 8601 format (YYYY-MM-DD)
+- Change types: Added, Changed, Deprecated, Removed, Fixed, Security
+- Bullet point lists for change items
+
+## Common Validation Errors
+
+### Missing Unreleased Section
+**Error**: "Unreleased section is mandatory for tracking upcoming changes"
+**Fix**: Add `## [Unreleased]` section at the top of version history
+
+### Invalid Version Format
+**Error**: "Version sections must use semantic versioning (X.Y.Z)"
+**Fix**: Use format `## [1.0.0] - 2026-01-06` not `## Version 1.0.0`
+
+### Invalid Date Format
+**Error**: "Date must be in ISO 8601 format: YYYY-MM-DD"
+**Fix**: Use `2026-01-06` not `Jan 6, 2026` or `01/06/2026`
+
+### Missing Change Type Subsections
+**Warning**: "Version should have at least one change type subsection"
+**Fix**: Add `### Added`, `### Fixed`, or other change type heading
+
+## Schema Extension Notes
+
+### Future Enhancements
+
+This schema could be extended with:
+
+1. **System Call Validation** (`x-markitect-validation-hooks`):
+   - Verify git tags match CHANGELOG versions
+   - Check version ordering consistency
+   - Validate date chronology
+
+2. **Agent Validation** (`x-markitect-validation-agents`):
+   - Semantic consistency checking
+   - Duplicate entry detection
+   - Version numbering logic validation
+
+3. **Cross-Reference Validation**:
+   - Link validation to issue trackers
+   - Commit hash verification
+   - Release note completeness checking
+
+## Keep a Changelog Standard
+
+This schema enforces the [Keep a Changelog](https://keepachangelog.com/en/1.0.0/) principles:
+
+- **Changelogs are for humans**, not machines
+- **One entry per version**
+- **Group changes by type** (Added, Changed, etc.)
+- **Versions and dates** for each release
+- **Latest version first**
+- **Unreleased section** for upcoming changes
+
+Combined with [Semantic Versioning](https://semver.org/), this enables consistent, readable version history.
+
+## Version History
+
+- **1.0** (2026-01-06): Initial schema release
+  - Basic structure validation
+  - Version and date format checking
+  - Change type subsection validation
+  - Keep a Changelog compliance

+# Release Management Optimization Implementation Plan
+
+**Date**: 2026-01-06
+**Status**: Ready to implement
+**Total Optimizations**: 9
+
+---
+
+## Implementation Order
+
+### Phase 1: High Priority (Critical Issues) - 5 hours
+1. Git status enhancement for unpushed tags (1 hour)
+2. Automated tag pushing (1 hour)
+3. CHANGELOG validation in release flow (2 hours)
+4. Version-tag consistency check (1 hour)
+
+### Phase 2: Medium Priority (UX & Automation) - 5.5 hours
+5. CHANGELOG section generation (3 hours)
+6. Explicit version command (30 minutes)
+7. Release summary auto-generation (2 hours)
+
+### Phase 3: Low Priority (Nice to Have) - 3 hours
+8. Schema auto-ingestion (1 hour)
+9. Release notes from CHANGELOG (2 hours)
+
+**Total Estimated Time**: 13.5 hours
+
+---
+
+## Optimization #1: Git Status Enhancement for Unpushed Tags
+
+**Priority**: HIGH
+**Estimated**: 1 hour
+**Files**: `capabilities/release-management/src/release_management/core/status.py`
+
+### Implementation Approach
+
+**Option 1**: Enhance `release status` command (RECOMMENDED)
+- Add unpushed tag detection to ReleaseStatus class
+- Compare local tags with remote tags
+- Display unpushed tags prominently
+
+**Option 2**: Git post-commit hook
+- Create .git/hooks/post-commit script
+- Automatic check after each commit
+- Less portable (per-clone setup)
+
+**Option 3**: Git alias
+- Add custom git alias in .gitconfig
+- User needs to remember to use it
+
+### Implementation Details

+        if 'refs/tags/' in line
+    ]
+
+    return [tag for tag in local_tags if tag and tag not in remote_tag_names]
+```
+
+### Success Criteria
+- ✅ `release status` shows unpushed tags
+- ✅ Clear warning when tags haven't been pushed
+- ✅ Works with multiple remotes
+
+---
+
+## Optimization #2: Automated Tag Pushing
+
+**Priority**: HIGH
+**Estimated**: 1 hour
+**Files**: `capabilities/release-management/src/release_management/cli/main.py`
+
+### Implementation
+
+Add `--push` flag to `release tag` command:
+
+```python
+@click.command()
+@click.argument('version')
+@click.option('--push/--no-push', default=False,
+              help='Automatically push tag to origin after creating')
+@click.option('--message', '-m', help='Tag annotation message')
+def tag(version, push, message):
+    """Create git tag for version."""
+    # Existing tag creation logic
+
+    if push:
+        click.echo(f"Pushing tag {tag_name} to origin...")
+        git_manager.push_tag(tag_name)
+        click.echo("✅ Tag pushed successfully")
+```
+
+### Success Criteria
+- ✅ `release tag v0.11.0 --push` creates AND pushes tag
+- ✅ Works with existing tag logic
+- ✅ Error handling for push failures

+
+### Success Criteria
+- ✅ `release prepare v0.11.0` creates section
+- ✅ Moves Unreleased content to new section
+- ✅ Validates result
+- ✅ Preserves formatting
+
+---
+
+## Optimization #6: Explicit Version Command
+
+**Priority**: MEDIUM
+**Estimated**: 30 minutes
+**Files**: `markitect/cli.py`
+
+### Implementation
+
+Add version subcommand to markitect CLI:

+
+## Optimization #8: Schema Auto-Ingestion
+
+**Priority**: LOW
+**Estimated**: 1 hour
+**Files**: `markitect/schema_loader.py`
+
+### Implementation
+
+Add auto-ingestion on build/install:

+- ✅ Can pipe to gh release or gitea
+
+---
+
+## Testing Strategy
+
+### Per-Optimization Testing
+1. Unit tests for each new class/function
+2. Integration tests for CLI commands
+3. Manual testing with real scenarios
+
+### End-to-End Testing
+1. Test full release workflow: prepare → validate → tag → build → summary
+2. Test error cases (invalid CHANGELOG, missing tags, etc.)
+3. Test with v0.11.0 as real-world scenario
+
+### Regression Testing
+- Ensure existing release commands still work
+- Backward compatibility with current workflows
+- No breaking changes to public APIs
+
+---
+
+## Rollout Plan
+
+### Phase 1: Foundation (Day 1, 5 hours)
+Implement high-priority items that prevent errors:
+1. Git status enhancement
+2. Automated tag pushing
+3. CHANGELOG validation
+4. Version-tag consistency
+
+**Deliverable**: Robust validation preventing v0.10.0-style issues
+
+### Phase 2: Automation (Day 2, 5.5 hours)
+Implement medium-priority UX improvements:
+5. CHANGELOG section generation
+6. Explicit version command
+7. Release summary auto-generation
+
+**Deliverable**: Streamlined release workflow
+
+### Phase 3: Polish (Day 3, 3 hours)
+Implement low-priority nice-to-haves:
+8. Schema auto-ingestion
+9. Release notes extraction
+
+**Deliverable**: Complete automated release toolchain
+
+---

+# Release Process Optimization Assessment
+
+**Date**: 2026-01-06
+**Context**: Post v0.10.0 release analysis
+**Completed**: Stages 1-2 (Critical Fixes + CHANGELOG Schema)
+
+---
+
+## Current Release Process Analysis
+
+### What We Did (Manual Steps)
+
+1. ✅ **Fixed version detection** (pyproject.toml)
+2. ✅ **Created retroactive tag** (git tag -a v0.9.0)
+3. ✅ **Updated CHANGELOG** (manual editing)
+4. ✅ **Created CHANGELOG schema** (manual schema writing)
+5. ✅ **Tagged release** (git tag -a v0.10.0)
+6. ✅ **Built packages** (release build)
+7. ⚠️ **Pushed commits** (git push) - but forgot tags!
+8. ❌ **Push tags** - MISSING: Need `git push --tags` or `git push origin v0.9.0 v0.10.0`
+
+### Issues Encountered
+
+#### 1. Tag Push Not Automatic ⚠️
+**Problem**: `git push` doesn't push tags by default
+**Impact**: Release tags not on remote, packages can't be built from remote
+**Current Workaround**: Remember to run `git push --tags` or `git push origin v0.9.0 v0.10.0`
+**Optimization**: Automate tag pushing in release workflow
+
+#### 2. Manual CHANGELOG Editing
+**Problem**: Hand-editing CHANGELOG.md is error-prone
+**Impact**: 
+- Risk of formatting errors
+- Time-consuming section management
+- No automatic version section creation
+**Current Workaround**: Careful manual editing
+**Optimization**: Automated CHANGELOG section generation
+
+#### 3. Version Command Not Explicit
+**Problem**: Only `markitect --version` works, no `markitect version` subcommand
+**Impact**: Inconsistent CLI UX (other tools have `version` subcommand)
+**Current Workaround**: Use --version flag
+**Optimization**: Add explicit version subcommand (Stage 3 deferred work)
+
+#### 4. No Pre-Release Validation
+**Problem**: No automated checks before tagging
+**Impact**: Could tag with:
+- Uncommitted changes
+- Unvalidated CHANGELOG
+- Version-tag mismatches
+**Current Workaround**: Manual verification
+**Optimization**: Pre-release validation hook (Stage 3 deferred work)
+
+#### 5. Schema Ingestion Manual
+**Problem**: New schemas require manual `schema-ingest` command
+**Impact**: Easy to forget, schema not in catalog
+**Current Workaround**: Remember to run after creating schema
+**Optimization**: Auto-detect and ingest schemas in build process
+
+#### 6. Git Status Doesn't Show Unpushed Tags ⚠️
+**Problem**: `git status` doesn't show tags that haven't been pushed to origin
+**Impact**:
+- Easy to forget to push tags after creating them
+- No visibility into unpushed tags (v0.9.0, v0.10.0 weren't pushed until manually noticed)
+- Tags from older versions also weren't pushed (discovered when pushing v0.10.0 tags)
+**Current Workaround**: Manually check `git ls-remote --tags origin` vs `git tag -l`
+**Optimization**: Enhanced git status or custom status command showing unpushed tags
+
+---
+
+## Optimization Opportunities
+
+### High Priority (Would Have Helped v0.10.0)
+
+#### 1. Git Status Enhancement for Unpushed Tags
+**Current**:
+```bash
+git status
+# On branch main
+# Your branch is up to date with 'origin/main'.
+# nothing to commit, working tree clean
+# ^ No mention of unpushed tags!
+```
+
+**Optimized**:
+```bash
+release status
+# OR: Enhanced git status via git hook
+# Shows:
+# - Current branch and commit status
+# - Unpushed tags: v0.9.0, v0.10.0
+# - Tags on origin vs local
+# - Reminder to push tags
+```
+
+**Implementation Options**:
+1. **Git post-commit hook**: Add .git/hooks/post-commit to check unpushed tags
+2. **Enhanced `release status`**: Add tag comparison to release status command
+3. **Git alias**: Create custom git alias for comprehensive status
+
+**Estimated Effort**: 1 hour
+**Impact**: Prevents forgotten tag pushes, immediate visibility
+
+#### 2. Automated Tag Pushing
+**Current**: 
+```bash
+git tag -a v0.10.0 -m "..."
+git push origin main
+# Oops, forgot tags!
+git push --tags
+```
+
+**Optimized**:
+```bash
+release tag v0.10.0
+# Automatically pushes both commits AND tags
+```
+
+**Implementation**: Add `--push` flag to `release tag` command
+**Estimated Effort**: 1 hour
+**Impact**: Prevents forgotten tag pushes
+
+#### 3. CHANGELOG Validation in Release Flow
+**Current**: Manual validation
+```bash
+markitect validate CHANGELOG.md --schema changelog-schema-v1.0.md --semantic
+```
+
+**Optimized**:
+```bash
+release validate
+# Automatically validates CHANGELOG with schema
+# Checks version-tag consistency
+# Reports any issues before tagging
+```
+
+**Implementation**: Integrate CHANGELOG validation into ReleaseManager (Stage 3)
+**Estimated Effort**: 2 hours
+**Impact**: Catches CHANGELOG errors before release
+
+#### 4. Version-Tag Consistency Check
+**Current**: Manual verification that CHANGELOG version matches tag
+
+**Optimized**:
+```bash
+release validate
+# Checks:
+# - CHANGELOG has section for target version
+# - Git tag matches CHANGELOG version
+# - No version-tag mismatches
+# - Unreleased section exists
+```
+
+**Implementation**: Add version consistency validator (Stage 3)
+**Estimated Effort**: 1 hour
+**Impact**: Prevents version confusion
+
+### Medium Priority (Nice to Have)
+
+#### 5. CHANGELOG Section Generation
+**Current**: Manually create `## [X.Y.Z] - YYYY-MM-DD` section
+
+**Optimized**:
+```bash
+release prepare v0.11.0
+# Automatically:
+# - Creates [0.11.0] - 2026-01-XX section
+# - Moves Unreleased content to new section
+# - Updates git describe version
+# - Validates CHANGELOG format
+```
+
+**Implementation**: CHANGELOG editor utility
+**Estimated Effort**: 3 hours
+**Impact**: Reduces manual editing, prevents format errors
+
+#### 6. Explicit Version Command
+**Current**: `markitect --version`
+
+**Optimized**:
+```bash
+markitect version
+# Shows:
+# - Current version (0.10.0)
+# - Latest tag (v0.10.0)
+# - Commits since tag (0)
+# - Dirty/clean status
+```
+
+**Implementation**: Add version subcommand to CLI (Stage 3)
+**Estimated Effort**: 30 minutes
+**Impact**: Better UX, more detailed version info
+
+#### 7. Release Summary Auto-Generation
+**Current**: Manually created comprehensive summary
+
+**Optimized**:
+```bash
+release summary v0.10.0
+# Generates:
+# - RELEASE_SUMMARY.md from CHANGELOG
+# - Git statistics
+# - Build artifacts info
+# - Testing results
+```
+
+**Implementation**: Summary generator using CHANGELOG + git metadata
+**Estimated Effort**: 2 hours
+**Impact**: Consistent release documentation
+
+### Low Priority (Future Enhancements)
+
+#### 8. Schema Auto-Ingestion
+**Current**: Manual `schema-ingest` after creating schema
+
+**Optimized**: Automatically detect new/updated schemas during build
+**Implementation**: Build hook that scans markitect/schemas/
+**Estimated Effort**: 1 hour
+**Impact**: Reduces manual steps
+
+#### 9. Release Notes from CHANGELOG
+**Current**: Copy CHANGELOG section manually
+
+**Optimized**:
+```bash
+release notes v0.10.0
+# Extracts CHANGELOG section for version
+# Formats for GitHub/Gitea release
+# Includes links to PRs/issues (if configured)
+```
+
+**Implementation**: CHANGELOG parser + formatter
+**Estimated Effort**: 2 hours
+**Impact**: Consistent release notes
+
+---
+

+**Implementation**: Check CHANGELOG version matches git describe
+**Estimated**: 1 hour
+
+### Task 3.3: Explicit Version Command
+**Status**: Not implemented
+**File**: `markitect/cli.py`
+**Command**: `markitect version`
+**Estimated**: 30 minutes
+
+**Total Stage 3 Effort**: ~2 hours
+
+---
+
+## Recommended Next Steps
+
+### Option A: Complete Stage 3 (2 hours)
+Implement deferred Stage 3 work:
+1. CHANGELOG validation in release manager
+2. Version-tag consistency checking
+3. Explicit version command
+
+**Benefits**:
+- Catches errors before they become problems
+- Completes release-management-optimization topic
+- Ready for v0.11.0 with better tooling
+
+**Timeline**: 1 session (2-3 hours)
+
+### Option B: Targeted Quick Wins (1 hour)
+Implement only high-priority optimizations:
+1. Automated tag pushing (--push flag)
+2. CHANGELOG validation command
+
+**Benefits**:
+- Solves immediate pain points
+- Minimal time investment
+- Can do Stage 3 later
+
+**Timeline**: 1 session (1-2 hours)
+
+### Option C: Move to Next Feature
+Keep release process as-is, focus on new work
+
+**Benefits**:
+- Release process functional (just remember tags!)
+- Can optimize later based on real pain points
+- Move forward with new features
+
+**Trade-offs**:
+- Manual steps remain
+- Risk of repeat mistakes
+
+---
+
+## Metrics
+
+### Current Process Efficiency
+
+**Time Breakdown (v0.10.0)**:
+- Planning/Investigation: 30 min
+- Stage 1 (Critical Fixes): 45 min
+- Stage 2 (CHANGELOG Schema): 90 min
+- Documentation: 20 min
+- Package Building: 5 min
+- **Total**: ~3 hours
+
+**Manual Steps**: 8 steps
+**Potential Automation**: 6 steps (tag status, tags, validation, version cmd, summary gen, schema ingest)
+
+**Error Rate**:
+- Forgot to push tags: 1 error
+- Version detection bugs: 1 error (fixed in Stage 1)
+- CHANGELOG format: 0 errors (schema caught issues)
+- Unpushed tags visibility: 1 critical issue (no git status warning)
+
+### With Stage 3 Optimizations
+
+**Estimated Time Savings**: 15-20 min per release
+- Pre-release validation: -5 min (automated)
+- Tag pushing: -2 min (automated)
+- Version consistency: -5 min (automated)
+- CHANGELOG validation: -5 min (automated)
+
+**Error Reduction**: ~80% (automated validation catches issues)
+
+**Process Quality**: High consistency, repeatable
+
+---
+
+## Conclusion
+
+### What Worked Well ✅
+1. Staged workplan approach (clear phases)
+2. CHANGELOG schema validation (caught format issues)
+3. Comprehensive documentation (workplan, summary)
+4. Build process smooth (release build worked perfectly)
+
+### What Could Improve ⚠️
+1. Tag pushing not automatic (forgot tags)
+2. Manual CHANGELOG editing (time-consuming)
+3. No pre-release validation (could miss errors)
+
+### Recommendation
+
+**Implement Option A: Complete Stage 3** (2 hours)
+
+**Rationale**:
+- Small time investment (2 hours)
+- High impact (prevents errors, saves time)
+- Completes release-management-optimization topic
+- Ready for smooth v0.11.0 release
+
+**Alternative**: If time-constrained, do Option B (1 hour) and defer remaining work
+
+---
+
+**Assessment Date**: 2026-01-06
+**Next Review**: After v0.11.0 release
+**Status**: Optimization opportunities identified, Stage 3 implementation recommended

+# Release Management Optimization
+
+**Created**: 2026-01-06
+**Status**: Planning → Ready to implement
+**Priority**: High (blocks v0.10.0 release)
+
+## Quick Summary
+
+Enhance release management with robust validation using the schema system we just built. Creates a perfect showcase: **validate CHANGELOG.md with a changelog schema**.
+
+## Critical Issues Found
+
+1. **setuptools-scm bug**: Missing tag_regex → `markitect --version` returns "unknown"
+2. **Missing v0.9.0 tag**: CHANGELOG says v0.9.0 released but git tag never created
+3. **No validation**: No checks for CHANGELOG format or version-tag consistency
+
+## Solution
+
+Create **changelog-schema-v1.0.md** to validate Keep a Changelog format, integrate into release workflow. Demonstrates schema evolution in action!
+
+## Staged Approach
+
+- **Stage 1** (45 min): Critical fixes → unblock v0.10.0 release
+- **Stage 2** (2.5 hrs): CHANGELOG schema → showcase feature
+- **Stage 3** (2 hrs): Release tooling enhancements
+- **Stage 4** (optional): Schema extensions (hooks/agents)
+
+**Recommended**: Standard Track (Stages 1-3) = 5 hours for production-ready release management
+
+## Files
+
+- `WORKPLAN.md` - Detailed staged implementation plan
+- `DONE.md` - Completion checklist (when finished)

+# MarkiTect v0.10.0 Release Summary
+
+**Release Date**: 2026-01-06
+**Tag**: v0.10.0
+**Philosophy**: "The release that validates itself"
+
+## Overview
+
+Successfully completed v0.10.0 release featuring the Schema Evolution system with a practical showcase: a CHANGELOG schema that validates its own version history file using the schema system it just built.
+
+## Release Stages Completed
+
+### ✅ Stage 1: Critical Fixes (~45 minutes)
+
+**Problem**: Version detection broken, missing git tags, release blocked
+
+**Solutions**:
+1. **Fixed setuptools-scm Configuration** (pyproject.toml)
+   - Added: `git_describe_command = "git describe --tags --long --match 'v*'"`
+   - Filters out non-version tags preventing setuptools-scm crashes
+   - `markitect --version` now works: returns `0.10.0` (previously "unknown")
+
+2. **Retroactive v0.9.0 Git Tag**
+   - Created annotated tag on commit b9c1b90 (2025-11-14)
+   - Restored version history integrity
+   - CHANGELOG documented v0.9.0 but tag was missing
+
+3. **CHANGELOG.md Updated**
+   - Created [0.10.0] - 2026-01-06 section
+   - Documented all fixes and features
+   - Moved Unreleased content to v0.10.0
+
+### ✅ Stage 2: CHANGELOG Schema (~90 minutes)
+
+**Goal**: Create showcase for schema evolution system
+
+**Deliverable**: `changelog-schema-v1.0.md` (360 lines)
+
+**Features Implemented**:
+1. **x-markitect-sections** (7 classifications)
+   - [Unreleased]: required
+   - Added/Changed/Deprecated/Removed/Fixed/Security: optional
+
+2. **x-markitect-content-control** (6 patterns)
+   - Title validation: Must be "Changelog"
+   - Version format: [X.Y.Z] - YYYY-MM-DD
+   - Date format: ISO 8601 (YYYY-MM-DD)
+   - Change types: Standard Keep a Changelog categories
+   - Reference links: Keep a Changelog and Semantic Versioning
+
+3. **x-markitect-validation-rules** (4 custom rules)
+   - Version format pattern
+   - Date format pattern
+   - Version ordering (descending)
+   - Unreleased position (first section)
+
+**Validation Results**:
+```
+✅ CHANGELOG.md validates successfully
+✅ All section requirements met (7 checked, 11 found)
+✅ All content requirements met
+✅ All semantic checks passing
+✅ Status: PASSED
+```

+
+## Philosophy Achievement
+
+> **"Use the tools we build to improve the tools we build."**
+
+This release achieves the meta-level goal:
+- ✅ v0.10.0 uses its own schema system to validate its CHANGELOG.md
+- ✅ Perfect demonstration of dogfooding infrastructure
+- ✅ Real-world showcase of x-markitect extensions
+- ✅ Practical proof-of-concept for schema evolution
+
+## Deferred Work
+
+### Stage 3: Release Capability Enhancements
+- CHANGELOG validation in ReleaseManager
+- Version-tag consistency checking
+- Explicit `markitect version` command
+- **Status**: Deferred to future enhancement
+- **Reason**: v0.10.0 release unblocked, showcase complete
+
+### Stage 4: Schema System Extensions
+- System call hooks (x-markitect-validation-hooks)
+- Agent validation (x-markitect-validation-agents)
+- **Status**: Not needed for current use case
+- **Reason**: Pure schema validation sufficient
+
+## Next Steps (Manual)
+
+1. **Push to origin** (requires authentication):
+   ```bash
+   git push origin main
+   git push origin v0.9.0 v0.10.0
+   ```
+
+2. **Publish packages** (if configured):
+   ```bash
+   release upload --registry pypi
+   ```
+
+3. **Create GitHub/Gitea release** (if applicable):
+   - Use v0.10.0 tag
+   - Attach wheel and tarball
+   - Copy CHANGELOG v0.10.0 section as release notes
+
+## Statistics
+
+- **Development Time**: ~2.5 hours (Stage 1: 45 min, Stage 2: 90 min)
+- **Commits**: 5 commits
+- **Tags**: 2 tags created (v0.9.0 retroactive, v0.10.0 release)
+- **Schemas**: 6 total schemas (1 new: changelog-schema-v1.0.md)
+- **Test Coverage**: 97 tests (Schema-of-Schemas), 25 tests (Semantic Validation)
+- **Code Added**: 360 lines (changelog schema), ~600 lines (workplan documentation)
+
+## Success Metrics
+
+### Stage 1 Criteria (Required for Release) ✅

+Enhance release management infrastructure with robust validation and automation, using the newly built schema system. This creates a practical showcase for the schema evolution capabilities while fixing critical release tooling issues.
+
+## Motivation
+
+### Current Issues
+
+1. **setuptools-scm Configuration Bug**
+   - Missing tag regex filter → picks up non-version tags
+   - Result: `markitect --version` returns "unknown"
+   - Impact: Users can't verify installed version
+
+2. **Version History Inconsistency**
+   - CHANGELOG shows v0.9.0 (2025-11-14) but git tag never created
+   - setuptools-scm sees v0.8.0 as latest
+   - 109 commits between v0.8.0 and current
+
+3. **No Validation Infrastructure**
+   - No CHANGELOG validation (format, version consistency)
+   - No pre-release checks for version/tag alignment
+   - No automated version bump validation
+
+4. **Missing CLI Features**
+   - No explicit `markitect --version` command
+   - Version info only via __version__.py fallback
+
+### Opportunity: Schema System Showcase
+
+Creating a **CHANGELOG schema** demonstrates:
+- Real-world use of x-markitect extensions
+- Schema validation for structured markdown
+- Section classification (Unreleased, versioned releases)
+- Content patterns (Keep a Changelog format)
+- Integration with release tooling
+
+**Perfect timing**: Release v0.10.0 with the tool that validates its own changelog!
+
+---
+
+## Goals
+
+### Primary
+1. ✅ **Fix setuptools-scm configuration** (blocks release)
+2. ✅ **Restore version history** (retroactive v0.9.0 tag)
+3. ✅ **Create CHANGELOG schema** (Keep a Changelog format)
+4. ✅ **Implement CHANGELOG validation** (pre-release check)
+
+### Secondary
+5. ⭐ **Add explicit version command** to markitect CLI
+6. ⭐ **Extend schema system** (if needed for system calls/agents)
+7. ⭐ **Release capability enhancements** (validation hooks)
+
+### Stretch
+8. 🎯 **Git tag validation** (ensure CHANGELOG ↔ tags sync)
+9. 🎯 **Automated version bumping** suggestions
+10. 🎯 **Release notes generation** from CHANGELOG
+
+---
+
+## Staged Workplan
+
+### Stage 1: Critical Fixes (Required for v0.10.0)
+
+**Goal**: Unblock immediate release
+
+#### Task 1.1: Fix setuptools-scm Configuration
+**File**: `pyproject.toml`
+
+**Current**:
+```toml
+[tool.setuptools_scm]
+write_to = "markitect/_version.py"
+```
+
+**Updated**:
+```toml
+[tool.setuptools_scm]
+write_to = "markitect/_version.py"
+version_scheme = "python-simplified-semver"
+tag_regex = "^v(?P<version>[0-9]+\\.[0-9]+\\.[0-9]+)$"
+local_scheme = "no-local-version"
+```
+
+**Validation**:
+- Run `python -c "from setuptools_scm import get_version; print(get_version())"`
+- Should show `0.8.1.dev109+g5e3646f` (or similar, based on v0.8.0 tag)
+- Run `markitect --version` → should show version (after reinstall)
+
+**Estimated**: 10 minutes
+
+#### Task 1.2: Restore Version History
+**Action**: Retroactively create v0.9.0 tag
+
+**Find v0.9.0 release commit**:
+```bash
+# Find commit around 2025-11-14 with plugin/rendering changes
+git log --since="2025-11-13" --until="2025-11-15" --oneline
+```
+
+**Create tag**:
+```bash
+# Tag the identified commit
+git tag -a v0.9.0 <commit-hash> -m "Release v0.9.0: Plugin infrastructure and TestDrive JSUI
+
+- Plugin Infrastructure Foundation
+- RenderingEngineManager
+- TestDrive JSUI Plugin
+- ChatGPT Document Theme
+- CLI Engine Parameter
+
+See CHANGELOG.md for full details."
+```
+
+**Validation**:
+- `git tag -l 'v*'` → should show v0.9.0
+- `git describe --tags --match='v*'` → should show v0.9.0-based description
+
+**Estimated**: 15 minutes
+
+#### Task 1.3: Prepare v0.10.0 Release
+**File**: `CHANGELOG.md`
+
+**Actions**:
+1. Move Unreleased content to v0.10.0 section
+2. Add release date
+3. Verify version links at bottom
+
+**Format**:
+```markdown
+## [Unreleased]
+
+## [0.10.0] - 2026-01-06
+
+### Added
+- **ADR Schema**: Architecture Decision Record validation schema
+  - 12 section classifications for comprehensive ADR structure
+  - Content pattern validation for formatting rules
+  - Quality metrics for completeness
+- **Markdown Schema Support**: Fixed validate and generate-stub commands
+  - load_schema_from_path() supports .json and .md files
+  - DocumentWrapper extracts headings from AST
+  - All schema commands now work with markdown schemas
+- **Schema Evolution Topic Closure**: Complete Phase 1-3 implementation
+  - 5 production schemas (manpage, API docs, terminology, schema-schema, ADR)
+  - Semantic validation system fully operational
+  - Template generation working with schemas
+
+### Fixed
+- setuptools-scm configuration with tag_regex for proper version detection
+- markitect --version now returns correct version instead of "unknown"
+- Semantic validator AST heading extraction via DocumentWrapper
+
+[Unreleased]: https://github.com/worsch/markitect/compare/v0.10.0...HEAD
+[0.10.0]: https://github.com/worsch/markitect/compare/v0.9.0...v0.10.0
+```
+
+**Estimated**: 20 minutes
+
+**Total Stage 1**: ~45 minutes
+
+---
+
+### Stage 2: CHANGELOG Schema (Showcase Feature)
+
+**Goal**: Create and validate CHANGELOG schema using schema evolution infrastructure
+
+#### Task 2.1: Analyze CHANGELOG Structure
+**Method**: Study Keep a Changelog format
+
+**Structure to validate**:
+```markdown
+# Changelog
+
+[preamble text]
+
+## [Unreleased]
+### Added / Changed / Deprecated / Removed / Fixed / Security
+- Bullet points
+
+## [X.Y.Z] - YYYY-MM-DD
+### Added / Changed / Deprecated / Removed / Fixed / Security
+- Bullet points
+
+[version links at bottom]
+```
+
+**Schema Requirements**:
+- **Sections**: Unreleased (required), Version sections (pattern: `[X.Y.Z]`)
+- **Subsections**: Added/Changed/Deprecated/Removed/Fixed/Security (optional)
+- **Content Patterns**:
+  - Version format: `\[(\d+\.\d+\.\d+)\]`
+  - Date format: `YYYY-MM-DD`
+  - Links at bottom: `[version]: url`
+- **Quality Metrics**:
+  - Each version should have at least one subsection
+  - Bullet points required in subsections
+
+**Estimated**: 30 minutes
+
+#### Task 2.2: Create changelog-schema-v1.0.md
+**File**: `markitect/schemas/changelog-schema-v1.0.md`
+
+**Schema structure**:
+```markdown
+---
+schema-id: "https://markitect.dev/schemas/changelog/v1.0"
+version: "1.0.0"
+status: "stable"
+domain: "changelog"
+description: "JSON schema for Keep a Changelog format with version history validation"
+---
+
+# Changelog Schema v1.0
+
+## Overview
+This schema validates CHANGELOG.md files following the Keep a Changelog format...
+
+## Schema Definition
+```json
+{
+  "$schema": "http://json-schema.org/draft-07/schema#",
+  "x-markitect-sections": {
+    "Unreleased": {
+      "classification": "required",
+      "heading_level": 2,
+      "error_message": "Unreleased section is mandatory for tracking upcoming changes"
+    },
+    // Version sections validated via pattern
+  },
+  "x-markitect-content-control": {
+    "unreleased": {
+      "content_quality": {
+        "min_words": 0  // Can be empty
+      }
+    },
+    // Version sections with date validation
+  }
+}
+```
+```
+
+**Considerations for Extension**:
+- **System Call Validation**: Check git tags match CHANGELOG versions
+  - `x-markitect-validation-hooks`: { "system": "git tag -l 'v*'" }
+  - Requires schema system extension
+
+- **Agent Validation**: Use AI to validate version consistency
+  - `x-markitect-validation-agents`: { "prompt": "Check versions align" }
+  - Requires agent integration
+
+**Decision**: Start with pure schema validation, add hooks/agents if needed
+
+**Estimated**: 90 minutes
+
+#### Task 2.3: Ingest and Test CHANGELOG Schema
+**Commands**:
+```bash
+# Ingest
+markitect schema-ingest markitect/schemas/changelog-schema-v1.0.md
+
+# Validate our CHANGELOG
+markitect validate CHANGELOG.md --schema changelog-schema-v1.0.md
+```
+
+**Expected**:
+- Section validation: Unreleased section present ✓
+- Version format validation: All versions follow X.Y.Z ✓
+- Date validation: ISO format YYYY-MM-DD ✓
+- Content structure: Subsections present ✓
+
+**Fix any issues found in CHANGELOG.md**
+
+**Estimated**: 30 minutes
+
+**Total Stage 2**: ~2.5 hours
+
+---
+
+### Stage 3: Release Capability Enhancements
+
+**Goal**: Integrate CHANGELOG validation into release workflow
+
+#### Task 3.1: Add CHANGELOG Validation to Release Manager
+**File**: `capabilities/release-management/src/release_management/core/manager.py`
+
+**Add validation method**:
+```python
+def validate_changelog(self) -> tuple[bool, list[str]]:
+    """Validate CHANGELOG.md against changelog schema."""
+    from markitect.cli import validate_against_schema
+
+    changelog_path = self.project_root / "CHANGELOG.md"
+    schema_path = self.project_root / "markitect/schemas/changelog-schema-v1.0.md"
+
+    if not changelog_path.exists():
+        return False, ["CHANGELOG.md not found"]
+
+    is_valid = validate_against_schema(changelog_path, schema_path)
+    if not is_valid:
+        return False, ["CHANGELOG.md validation failed"]
+
+    return True, []
+```
+
+**Integrate into validate_release_state()**:
+```python
+def validate_release_state(self) -> tuple[bool, list[str]]:
+    issues = []
+
+    # Existing validations...
+
+    # Add CHANGELOG validation
+    changelog_valid, changelog_issues = self.validate_changelog()
+    if not changelog_valid:
+        issues.extend(changelog_issues)
+
+    return len(issues) == 0, issues
+```
+
+**Estimated**: 45 minutes
+
+#### Task 3.2: Add Version-Tag Consistency Check
+**Feature**: Verify CHANGELOG versions match git tags
+
+**Method**:
+```python
+def check_version_tag_consistency(self) -> tuple[bool, list[str]]:
+    """Check CHANGELOG versions have corresponding git tags."""
+    import re
+
+    # Parse CHANGELOG for versions
+    changelog = (self.project_root / "CHANGELOG.md").read_text()
+    versions = re.findall(r'## \[(\d+\.\d+\.\d+)\]', changelog)
+
+    # Get git tags
+    result = subprocess.run(['git', 'tag', '-l', 'v*'],
+                          capture_output=True, text=True)
+    tags = result.stdout.strip().split('\n')
+    tag_versions = [t.lstrip('v') for t in tags if t.startswith('v')]
+
+    # Check consistency
+    issues = []
+    for version in versions:
+        if version not in tag_versions:
+            issues.append(f"CHANGELOG version {version} has no git tag v{version}")
+
+    return len(issues) == 0, issues
+```
+
+**Estimated**: 45 minutes
+
+#### Task 3.3: Add Explicit Version Command
+**File**: `markitect/cli.py`
+
+**Add command**:
+```python
+@cli.command()
+def version():
+    """Display detailed version information."""
+    from markitect.__version__ import get_version_info
+
+    info = get_version_info()
+
+    click.echo(f"MarkiTect {info['full_version']}")
+    click.echo(f"Git Commit: {info['git_commit']}")
+    click.echo(f"Git Branch: {info['git_branch']}")
+
+    if info['is_dev']:
+        click.echo("⚠️  Development version (not released)")
+    else:
+        click.echo(f"✅ Released version")
+```
+
+**Update --version option**:
+```python
+@click.version_option(version=get_version(), prog_name="markitect")
+def cli():
+    ...
+```
+
+**Estimated**: 30 minutes
+
+**Total Stage 3**: ~2 hours
+
+---
+
+### Stage 4: Schema System Extensions (If Needed)
+
+**Goal**: Add validation hooks for system calls and agents
+
+**Only implement if pure schema validation insufficient**
+
+#### Option A: System Call Hooks
+**Extension**: `x-markitect-validation-hooks`
+
+```json
+{
+  "x-markitect-validation-hooks": {
+    "pre-validation": [
+      {
+        "name": "check-git-tags",
+        "command": "git tag -l 'v*'",
+        "parser": "lines",
+        "validation": {
+          "min_count": 5,
+          "pattern": "^v\\d+\\.\\d+\\.\\d+$"
+        }
+      }
+    ]
+  }
+}
+```
+
+**Implementation**:
+- Add HookValidator to validators package
+- Execute system commands securely
+- Parse and validate output
+- Integrate into SemanticValidator
+
+**Estimated**: 3 hours
+
+#### Option B: Agent Validation
+**Extension**: `x-markitect-validation-agents`
+
+```json
+{
+  "x-markitect-validation-agents": {
+    "consistency-check": {
+      "prompt": "Verify all CHANGELOG versions have corresponding git tags",
+      "context": ["CHANGELOG.md", "git tag -l"],
+      "severity": "warning"
+    }
+  }
+}
+```
+
+**Implementation**:
+- Add AgentValidator to validators package
+- Integration with LLM/agent framework
+- Structured output parsing
+- Integrate into SemanticValidator
+
+**Estimated**: 4 hours
+
+**Decision Point**: Only proceed if needed for CHANGELOG validation
+
+**Total Stage 4**: 0-7 hours (conditional)
+
+---
+
+## Success Criteria
+
+### Stage 1 (Required for Release)
+- ✅ `markitect --version` returns actual version (not "unknown")
+- ✅ v0.9.0 git tag exists
+- ✅ CHANGELOG.md has v0.10.0 section
+- ✅ v0.10.0 ready for tagging
+
+### Stage 2 (Showcase Feature)
+- ✅ changelog-schema-v1.0.md created and ingested
+- ✅ CHANGELOG.md validates against schema
+- ✅ Schema demonstrates Keep a Changelog format validation
+
+### Stage 3 (Enhanced Tooling)
+- ✅ Release validation includes CHANGELOG check
+- ✅ Version-tag consistency checking works
+- ✅ `markitect version` command available
+
+### Stage 4 (Optional Extensions)
+- ⭐ System call hooks functional (if implemented)
+- ⭐ Agent validation working (if implemented)
+
+---
+
+## Timeline Estimate
+
+### Fast Track (Stage 1 Only)
+- **Time**: 45 minutes
+- **Scope**: Critical fixes for v0.10.0 release
+- **Result**: Can release immediately
+
+### Standard Track (Stages 1-3)
+- **Time**: 5 hours
+- **Scope**: Fixes + CHANGELOG schema + tooling enhancements
+- **Result**: Production-ready release management
+
+### Full Track (Stages 1-4)
+- **Time**: 5-12 hours (depends on extensions needed)
+- **Scope**: Complete system with validation hooks/agents
+- **Result**: Advanced validation infrastructure
+
+---
+
+## Decision Points
+
+### 1. Release Strategy
+**Options**:
+- A. Fast track → Release v0.10.0 now with Stage 1 fixes only
+- B. Standard track → Complete Stages 1-3, release as v0.10.1 or v0.11.0
+- C. Full track → Include Stage 4, major release v1.0.0
+
+**Recommendation**: **Option B (Standard Track)**
+- Showcases schema system with real use case
+- Improves release tooling robustly
+- Reasonable timeline (5 hours)
+- Release as **v0.10.0** with all features
+
+### 2. Schema Extensions
+**When to implement**:
+- Stage 4 only if pure schema validation can't handle:
+  - Git tag checking (may need system call hook)
+  - Version consistency (may need agent validation)
+
+**Recommendation**: **Start without extensions**
+- Try pure schema validation first
+- Add hooks/agents only if needed
+- Document extension needs for future enhancement
+
+### 3. release-management Extraction
+**Question**: Make it a git submodule?
+
+**Current**: Regular directory (not extracted)
+
+**Recommendation**: **Defer to future**
+- Not blocking for release
+- Works fine as capability
+- Can extract later if needed for reuse
+
+---
+
+## Files to Create/Modify
+
+### Create
+- `markitect/schemas/changelog-schema-v1.0.md` - CHANGELOG validation schema
+- `roadmap/260106-release-management-optimization/DONE.md` - Completion checklist (when done)
+
+### Modify
+- `pyproject.toml` - Fix setuptools-scm configuration
+- `CHANGELOG.md` - Add v0.10.0 section, fix format if needed
+- `markitect/cli.py` - Add explicit version command
+- `capabilities/release-management/src/release_management/core/manager.py` - Add CHANGELOG validation
+- (Optional) `markitect/validators/` - Add hook/agent validators if needed
+
+### Git Operations
+- Create v0.9.0 tag retroactively
+- Create v0.10.0 tag for release
+
+---
+
+## Risks & Mitigations
+
+### Risk 1: Retroactive Tagging
+**Issue**: Creating v0.9.0 tag retroactively might confuse users
+
+**Mitigation**:
+- Document in CHANGELOG that tag was missing
+- Use tag message to explain retroactive creation
+- Don't publish v0.9.0 packages (already past that release)
+
+### Risk 2: Schema Extensions Complexity
+**Issue**: Implementing hooks/agents might be complex
+
+**Mitigation**:
+- Start with pure schema validation
+- Only add extensions if necessary
+- Document extension API for future
+
+### Risk 3: CHANGELOG Format Variations
+**Issue**: Real-world CHANGELOGs may not match Keep a Changelog exactly
+
+**Mitigation**:
+- Make schema flexible with optional sections
+- Use warnings instead of errors for style issues
+- Support alternative section names
+
+---

+# MarkiTect Project Roadmap
+
+This roadmap directory contains planning directories for roadmap topics.
+- When starting to implement a topic its directory will be timestamped
+- If implementing multiple topics in parallel use branches
+- Keep current state of what's next to implement in TODO.md
+- See ../history directory for closed topics
+
+## Naming Convention
+
+**Directory Format:** `yymmdd-topic-name`
+
+- Use 2-digit year prefix (e.g., `260106-` for 2026-01-06)
+- Lowercase topic names with hyphens
+- Examples: `260106-semantic-document-validation`, `260105-schema-evolution`
+
+This convention keeps names concise while maintaining chronological sorting.
+
+## Purpose
+
+This planning documentation serves multiple purposes:
+
+1. **Implementation State Awareness**: Allow for recovery after breaks or breakdowns
+2. **Minimal Plan-Implement Loop**: Don't complicate agentic coding with issue tracking if unnecessary
+3. **Planning Info Analysis**: Keeping the planning info allows for retrospective analyses to optimize
+4. **Clean Repo Structure**: Using roadmap/ for planning and TODO.md as current state helps stay organized
