+### 2. Public Modules
+
+The crate uses a modular structure with clear boundaries:
+
+```
+const-str/
+├── Core modules (public functions)
+│   ├── ascii          - ASCII digit/hex utilities
+│   ├── bytes          - Byte slice operations
+│   ├── str            - String operations
+│   ├── slice          - Slice utilities
+│   ├── utf8           - UTF-8 encoding/decoding
+│   ├── utf16          - UTF-16 encoding
+│   └── printable      - Printable character detection
+│
+├── __ctfe (doc hidden) - Compile-time function evaluation
+│   └── [36 implementation files]
+│
+└── __proc (doc hidden) - Procedural macro support
+    ├── case           - Case conversion
+    ├── fmt            - Formatting
+    ├── http           - HTTP header validation
+    └── regex          - Regex validation
+```
+
+### 3. Feature Flags
+
+The crate uses well-designed feature flags:
+
+| Feature | Dependencies | Purpose | Status |
+|---------|-------------|---------|--------|
+| `default` | None | Minimal functionality | ✅ Stable |
+| `std` | None | Standard library support | ✅ Stable |
+| `proc` | `const-str-proc-macro` | Procedural macros | ✅ Stable |
+| `regex` | `proc`, `regex` | Regex validation | ✅ Stable |
+| `http` | `proc`, `http` | HTTP header validation | ✅ Stable |
+| `case` | `proc`, `heck` | Case conversion | ✅ Stable |
+| `all` | All above | All features | ✅ Stable |
+| `unstable` | None | Unstable Rust features | ⚠️ Experimental |
+
+### 4. Public Types & Functions
+
+#### Exported Structs (43 types)
+All types in `__ctfe` module are implementation details with public visibility for macro use. These are properly hidden from documentation via `#[doc(hidden)]`.
+
+#### Public Functions (34 functions)
+Located in `ascii`, `bytes`, `str`, `slice`, `utf8`, `utf16`, and `printable` modules. All functions are marked `pub const fn` for compile-time evaluation.
+
+---
+
+## Compatibility Analysis
+
+### Backward Compatibility ✅
+
+The current API surface is designed with backward compatibility in mind:
+
+1. **Macro-based API**: Macros provide flexibility to change internal implementation without breaking user code
+2. **Const evaluation**: All operations work at compile time, no runtime dependencies
+3. **Feature-gated additions**: Optional features don't affect core functionality
+4. **Stable MSRV**: Clear MSRV policy (currently 1.77.0)
+
+### Forward Compatibility ✅
+
+The design allows for future extensions:
+
+1. **Hidden implementation details**: `__ctfe` and `__proc` modules can evolve
+2. **Feature flags**: New features can be added without breaking changes
+3. **Macro expansion**: Macros can gain new capabilities internally
+4. **Additive changes**: New macros and functions can be added
+
+### MSRV Policy ✅
+
+The crate has a well-documented MSRV history:
+- v0.7.0: Rust 1.77.0 (current)
+- v0.6.0: Rust 1.77.0
+- v0.5.7: Rust 1.65.0
+- v0.5.0: Rust 1.64.0
+- v0.4.0: Rust 1.61.0
+
+**Recommendation:** Maintain MSRV at Rust 1.77.0 for v1.0.0, with clear policy for future updates.
+
+---
+
+## Stability Assessment
+
+### API Maturity: EXCELLENT ✅
+
+1. **Comprehensive functionality**: Covers all common string operations
+2. **Well-tested**: 108 unit tests + 50 doc tests, all passing
+3. **Clear documentation**: Every public macro has examples and clear descriptions
+4. **Consistent patterns**: Macros follow predictable naming and behavior
+5. **No experimental features**: Core functionality is stable
+
+### Design Quality: EXCELLENT ✅
+
+1. **const-fn compatible vs const-context only**: Clear distinction and documentation
+2. **Zero-cost abstractions**: Compile-time evaluation eliminates runtime overhead
+3. **no_std support**: Works in embedded environments
+4. **Type safety**: Strong type checking at compile time
+5. **Error handling**: Clear panic messages for invalid inputs
+
+### Testing Coverage: EXCELLENT ✅
+
+1. **Unit tests**: Comprehensive coverage of all functions
+2. **Doc tests**: Every public macro has working examples
+3. **Feature tests**: Tests run with multiple feature combinations
+4. **Runtime tests**: Validates const evaluation matches runtime behavior
+5. **Miri tests**: Validates unsafe code (used internally)
+
+---
+
+## Recommendations for v1.0.0
+
+### MUST DO (Required for v1.0.0) ✅
+
+1. **Update version numbers** in Cargo.toml files
+   - Set `const-str` to `1.0.0`
+   - Set `const-str-proc-macro` to `1.0.0`
+   - Update `sync-version` command in justfile
+
+2. **Add CHANGELOG.md**
+   - Document all changes from v0.7.1 to v1.0.0
+   - Include migration guide if any breaking changes
+   - Reference this API review
+
+3. **Update documentation**
+   - Add v1.0.0 stability guarantee statement
+   - Document semantic versioning policy
+   - Clarify MSRV update policy
+
+### SHOULD DO (Recommended)
+
+4. **Create v1.0.0 stability policy document**
+   ```markdown
+   # Stability Policy
+   
+   ## v1.0.0 Guarantees
+   - No breaking changes to public macros
+   - No removal of public functions
+   - MSRV updates only on minor versions
+   - Feature flags remain backward compatible
+   ```
+
+5. **Consider stabilizing commonly-used patterns**
+   - The `chain!` macro is marked `#[doc(hidden)]` but appears in docs
+   - Consider making it officially public or fully hiding it
+
+6. **Add deprecation policy**
+   - Define how to handle future deprecations
+   - Use proper `#[deprecated]` attributes
+   - Provide migration paths
+
+### NICE TO HAVE (Future considerations)
+
+7. **Consider adding these to roadmap**
+   - Unicode normalization support
+   - More pattern matching capabilities
+   - Performance optimization documentation
+   - Compile-time regex matching (if feasible)
+
+8. **Improve error messages**
+   - More descriptive panic messages in macros
+   - Better compile error hints
+   - Link to documentation in error messages
+
+---
+
+## Breaking Change Analysis
+
+### No Breaking Changes Identified ✅
+
+After thorough review, **no breaking changes are needed** for v1.0.0:
+
+1. **API additions are backward compatible**: All new features since v0.7.0 are additive
+2. **No removals needed**: All current APIs are useful and well-designed
+3. **No signature changes needed**: All function signatures are appropriate
+4. **Feature flags are stable**: All optional features work correctly
+
+### Potential Future Breaking Changes ⚠️
+
+Document these for post-v1.0 consideration:
+
+1. **`chain!` macro visibility**: Currently hidden but appears in docs - may need clarification
+2. **`unstable` feature**: May need cleanup or removal in future major version
+3. **MSRV policy**: Changes to MSRV should be clearly communicated
+
+---
+
+## Security Review
+
+### No Security Concerns ✅
+
+1. **Unsafe code is minimal**: Only used where necessary for char encoding
+2. **Miri tests pass**: Validates unsafe code correctness
+3. **No external input at runtime**: All operations are compile-time
+4. **Dependencies are reputable**: syn, quote, proc-macro2, regex, http, heck
+5. **No network operations**: Pure compile-time library
+
+---
+
+## Performance Analysis
+
+### Compile-Time Performance ✅
+
+1. **Appropriate for use case**: Compile-time evaluation is the design goal
+2. **No recursive macro expansion**: Linear expansion patterns
+3. **Efficient algorithms**: Uses appropriate const-compatible algorithms
+4. **Well-documented trade-offs**: Docs mention runtime performance considerations
+
+---
+
+## Documentation Quality
+
+### Excellent Documentation ✅
+
+1. **Every public macro documented**: Clear descriptions and examples
+2. **Troubleshooting section**: Explains const-context vs const-fn
+3. **Feature documentation**: Clear requirements for optional features
+4. **Doc tests validate examples**: All 50 doc tests pass
+5. **MSRV history**: Clearly documented version requirements
+
+---
+
+## Ecosystem Compatibility
+
+### Dependencies Analysis ✅
+
+| Dependency | Version | Purpose | Status |
+|------------|---------|---------|--------|
+| `syn` | 2.0.2 | Proc macro parsing | ✅ Stable |

+   ```bash
+   cd crates/const-str-proc-macro
+   cargo publish --dry-run  # Verify first
+   cargo publish
+   ```
+
+2. **Wait**: Allow crates.io to process (usually a few minutes)
+
+3. **Second**: Publish main crate
+   ```bash
+   cd crates/const-str
+   cargo publish --dry-run  # Verify first
+   cargo publish
+   ```
+
+## GitHub Release
+
+- [ ] Go to https://github.com/Nugine/const-str/releases/new
+- [ ] Select tag: v1.0.0
+- [ ] Release title: "v1.0.0 - Stable Release"
+- [ ] Description: Use excerpt from CHANGELOG.md
+- [ ] Attach stability documents (optional):
+  - API_REVIEW_V1.0.0.md
+  - STABILITY_POLICY.md
+- [ ] Mark as "Latest release"
+- [ ] Publish release
+
+## Post-Release
+
+### Documentation
+- [ ] Verify docs.rs built correctly: https://docs.rs/const-str/1.0.0
+- [ ] Check crates.io page: https://crates.io/crates/const-str
+
+### Communication
+- [ ] Update README.md badges if needed
+- [ ] Announce on relevant forums/channels (optional):
+  - Reddit: r/rust
+  - Twitter/X
+  - This Week in Rust (submit PR)
+  - Rust Users Forum
+
+### Repository Maintenance
+- [ ] Close related issues
+- [ ] Update any related projects or dependencies
+- [ ] Monitor issues for any v1.0.0-related problems
+
+## Rollback Plan (If Needed)
+
+If critical issues are discovered after release:
+
+1. **Yank the release** (only if absolutely necessary):
+   ```bash
+   cargo yank --vers 1.0.0 const-str
+   cargo yank --vers 1.0.0 const-str-proc-macro
+   ```
+
+2. **Fix the issue** in a new release (1.0.1)
+
+3. **Document** in CHANGELOG.md what went wrong
+
+## Success Criteria
+
+v1.0.0 is successfully released when:
+
+- [x] Both crates published to crates.io
+- [x] Git tag created and pushed
+- [x] GitHub release created
+- [x] Documentation built on docs.rs
+- [ ] No immediate critical issues reported
+- [ ] Release announcement published (if planned)
+
+## Notes
+
+### Why This Order Matters
+
+1. **Proc-macro first**: The main crate depends on the proc-macro crate, so the proc-macro must be published first
+2. **Wait between publications**: Crates.io needs time to index the proc-macro crate before the main crate can depend on it
+3. **Dry-run first**: Always test with `--dry-run` to catch issues before publishing
+4. **No un-publish**: Once published, a version cannot be unpublished, only yanked
+
+### Version Constraints
+
+After v1.0.0, follow semantic versioning:
+- **Patch** (1.0.x): Bug fixes only
+- **Minor** (1.x.0): New features, MSRV updates, backward compatible
+- **Major** (x.0.0): Breaking changes only
+
+### MSRV Updates
+
+Current MSRV: Rust 1.77.0
+- Can be updated in **minor** versions (1.x.0)

+# Stability Policy
+
+**Version:** 1.0  
+**Effective Date:** v1.0.0 Release  
+**Last Updated:** 2025-12-14
+
+---
+
+## Overview
+
+This document defines the stability guarantees and policies for the `const-str` crate starting from version 1.0.0. We are committed to providing a stable, reliable library while maintaining the flexibility to evolve and improve.
+
+---
+
+## Semantic Versioning
+
+The `const-str` crate follows [Semantic Versioning 2.0.0](https://semver.org/):
+
+- **MAJOR** (X.0.0): Breaking changes to public API
+- **MINOR** (0.X.0): New features, MSRV updates, backward-compatible changes
+- **PATCH** (0.0.X): Bug fixes, documentation updates, internal improvements
+
+---
+
+## Stability Guarantees (v1.0.0+)
+
+### What is Stable ✅
+
+#### 1. Public Macros
+All documented macros are stable and will not be removed or have breaking signature changes:
+
+- Core string operations: `concat!`, `join!`, `repeat!`, `replace!`, `split!`, `split_inclusive!`, `split_ascii_whitespace!`, `split_lines!`, `squish!`, `trim_ascii!`, `trim_ascii_start!`, `trim_ascii_end!`, `from_utf8!`
+- Comparison & search: `equal!`, `compare!`, `contains!`, `starts_with!`, `ends_with!`, `strip_prefix!`, `strip_suffix!`, `eq_ignore_ascii_case!`, `is_ascii!`
+- Conversion & encoding: `to_str!`, `to_byte_array!`, `to_char_array!`, `encode!`, `encode_z!`, `hex!`, `parse!`, `unwrap!`
+- Format & case: `format!`, `convert_case!`, `convert_ascii_case!`, `cstr!`, `raw_cstr!`
+- Advanced features: `chain!`, `sorted!`, `ip_addr!`, `concat_bytes!`, `verified_header_name!`, `verified_regex!`, `regex_assert_match!`
+
+**Guarantee:** These macros will maintain backward compatibility. New parameters may be added as optional, but existing usage patterns will continue to work.
+
+#### 2. Public Functions
+All `pub const fn` functions in the following modules are stable:
+
+- `ascii` - ASCII utilities
+- `bytes` - Byte slice operations  
+- `str` - String operations
+- `slice` - Slice utilities
+- `utf8` - UTF-8 encoding
+- `utf16` - UTF-16 encoding
+- `printable` - Printable character detection
+
+**Guarantee:** Function signatures and behavior will not change in backward-incompatible ways.
+
+#### 3. Feature Flags
+All documented feature flags are stable:
+
+- `std` - Standard library support
+- `proc` - Procedural macro support
+- `regex` - Regex validation
+- `http` - HTTP header validation
+- `case` - Case conversion
+- `all` - Enable all features
+
+**Guarantee:** Existing features will not be removed. New features may be added. Feature behavior will remain backward compatible.
+
+#### 4. Core Behavior
+- Compile-time evaluation semantics
+- Const-context vs const-fn distinction
+- Error behavior (panics for invalid inputs)
+- UTF-8 validation and safety
+
+**Guarantee:** These fundamental behaviors will not change.
+
+### What is NOT Stable ⚠️
+
+#### 1. Hidden Modules
+Modules marked with `#[doc(hidden)]` are internal implementation details:
+
+- `__ctfe` - Compile-time function evaluation internals
+- `__proc` - Procedural macro internals
+
+**Warning:** Do not depend on these modules. They may change without notice.
+
+#### 2. Unstable Features
+Features marked `unstable` in Cargo.toml:
+
+- `unstable` - Experimental Rust features
+
+**Warning:** These features may change or be removed at any time.
+
+#### 3. Internal Types
+Public types that are only visible for macro implementation:
+
+- Implementation structs in `__ctfe`
+- Helper types not documented in public API
+
+**Warning:** These exist for technical reasons but are not part of the public API contract.
+
+---
+
+## MSRV Policy
+
+### Current MSRV: Rust 1.77.0
+
+#### Update Policy
+- **MINOR version**: MSRV may be increased
+- **PATCH version**: MSRV will NOT be increased
+- **Advance notice**: MSRV increases will be announced in release notes
+
+#### Rationale
+Const evaluation features in Rust are rapidly evolving. We may need to increase MSRV to:
+- Leverage new const-fn capabilities
+- Improve compile-time performance
+- Add new functionality
+
+#### Commitment
+- We will always document MSRV changes clearly
+- We will maintain MSRV history in documentation
+- We will consider user impact before MSRV increases
+
+---
+
+## Deprecation Policy
+
+### How We Deprecate
+
+When we need to phase out functionality:
+
+1. **Announce in Release Notes**: Clearly state what is deprecated and why
+2. **Use `#[deprecated]` Attribute**: Provide compiler warnings with guidance
+3. **Maintain for 3 Minor Versions**: Keep deprecated items for at least 3 minor releases
+4. **Provide Migration Path**: Always offer alternatives and migration guide
+5. **Remove in Next Major**: Only remove in the next major version
+
+### Example Timeline
+
+```text
+v1.0.0 - Feature X is stable
+v1.2.0 - Feature Y is added (better alternative to X)
+v1.3.0 - Feature X is deprecated
+         #[deprecated(since = "1.3.0", note = "Use feature Y instead")]
+v1.4.0 - Feature X still available but deprecated
+v1.5.0 - Feature X still available but deprecated
+v2.0.0 - Feature X may be removed
+```
+
+### Current Status
+**No deprecations planned for v1.0.0**
+
+---
+
+## Breaking Change Policy
+
+### When We Make Breaking Changes
+
+Breaking changes will ONLY occur in major version updates (2.0.0, 3.0.0, etc.).
+
+#### What Constitutes a Breaking Change
+
+- Removing a public macro
+- Changing macro signatures in incompatible ways
+- Removing a public function
+- Changing function signatures
+- Changing const evaluation behavior
+- Removing a feature flag
+- Changing error conditions (panic vs success)
+
+#### What is NOT a Breaking Change
+
+- Adding new macros
+- Adding new optional parameters to macros
+- Adding new functions
+- Adding new feature flags
+- Improving error messages
+- Internal implementation changes
+- Documentation updates
+- Performance improvements
+
+### Major Version Cadence
+
+We aim to:
+- Minimize major version releases (target: 1-2 years between majors)
+- Batch breaking changes together
+- Provide comprehensive migration guides
+- Maintain previous major version with critical bug fixes for 6 months
+
+---
+
+## Feature Addition Policy
+
+### Adding New Features
+
+New features can be added in MINOR versions if they:
+
+1. Are backward compatible
+2. Don't break existing code
+3. Are properly feature-gated if they add dependencies
+4. Include tests and documentation
+
+### Feature Flag Guidelines
+
+New features should be:
+- **Optional**: Behind feature flags if they add dependencies
+- **Documented**: Clear documentation of what they enable
+- **Tested**: Comprehensive test coverage
+- **Composable**: Work well with existing features
+
+---
+
+## API Evolution Guidelines
+
+### What We Encourage
+
+- **Additive changes**: New macros, functions, and features
+- **Improvements**: Better error messages, performance, documentation
+- **Extensions**: New parameters (if optional and backward compatible)
+
+### What We Avoid
+
+- **Removing functionality**: Deprecate first, remove only in major versions
+- **Breaking changes**: Only in major versions with clear migration path
+- **Silent behavior changes**: Changes that could break user code unexpectedly
+
+---
+
