Closes the only previously-open decision in the register. Chanora is
now dual-licensed under either:
* Apache License, Version 2.0 (LICENSE-APACHE), OR
* MIT License (LICENSE-MIT)
at the recipient's option. This is the standard Rust-ecosystem
permissive model and is compatible with every direct dependency
in the PoC tree:
tsclientlib MIT OR Apache-2.0
flutter_rust_bridge MIT
cpal Apache-2.0
rusqlite MIT
keyring MIT OR Apache-2.0
hound Apache-2.0
ndk-context, jni, android_logger, regex, serde, tokio,
tracing, thiserror, zeroize, etc. MIT OR Apache-2.0
and with the Flutter framework's BSD-3-Clause.
Files added:
- LICENSE-APACHE Apache 2.0 license text.
- LICENSE-MIT MIT license text with the standard 2026 copyright
line.
Files updated:
- LICENSE Now the dual-license aggregator. Includes the standard
Apache-2.0 inbound-contribution clause ("Unless you
explicitly state otherwise, any contribution
intentionally submitted for inclusion in Chanora by you,
as defined in the Apache-2.0 license, shall be
dual-licensed as above, without any additional terms or
conditions.").
- NOTICE Rewritten with the dual-license declaration and an
inventory of direct dependencies with their upstream
licenses. Transitive deps remain to be enumerated by
build tooling (cargo about, Flutter LicenseRegistry).
- README.md §License section rewritten to point at LICENSE-APACHE
and LICENSE-MIT.
- docs/governance/product-decision-register.md v0.9.5 → v0.9.6:
DEC-020 status: Open → Accepted. §4 license row updated. §6
collapsed: every previously-Proposed or Open decision in the
register is now resolved. DEC-012 legal review remains as a
release-gating *work* item, but is not an open decision.
- docs/governance/poc-results-summary.md v0.3.0 → v0.4.0:
RISK-PoC-003 closed. DEC-020 row moved out of 'Still open'.
This is a license-model commitment, not a substitute for the
DEC-012 legal review. Per DEC-012 the actual legal review work
(transitive-dep OSS obligations, trademark registrability, final
sign-off on the non-affiliation wording) must still be completed
before any public/store release; that is sign-off work, not an
architectural decision.

Chanora
Chanora is a cross-platform voice communication client for TeamSpeak-compatible servers.
It is built with a shared Flutter UI and a Rust core, with TeamSpeak-compatible protocol integration isolated behind tsclientlib.
Flutter UI + Rust Core + tsclientlib
Chanora is an independent project and is not affiliated with, endorsed by, sponsored by, or officially associated with TeamSpeak.
Status
Chanora is currently in early planning and baseline-candidate design.
Current documentation baseline: v0.9.2
Current status: Baseline Candidate
Implementation status: Not production-ready
The current engineering focus is:
- defining the system and software architecture;
- preparing the Flutter + Rust application structure;
- validating TeamSpeak-compatible protocol integration through
tsclientlib; - defining cross-platform audio behavior;
- preparing release, verification, security, privacy, and legal gates.
Target Platforms
Chanora is intended to support:
- Windows
- macOS
- Linux
- Android
- iOS / iPadOS
Current platform policy:
| Platform | Baseline |
|---|---|
| iOS / iPadOS runtime target | iOS 13+ unless Flutter, plugin, audio, or product constraints require raising it |
| App Store Connect upload gate | Xcode 26+ with iOS 26 / iPadOS 26 SDK+ for upload on or after 2026-04-28 |
| Android runtime target | Android API 24+ unless Flutter, plugin, audio, or product constraints require raising it |
| Google Play target API | Target the Google Play-required API level on upload date |
The App Store / Play Store upload gates are release requirements. They are separate from local development and internal testing requirements.
Architecture Overview
Chanora separates UI, protocol logic, state synchronization, audio processing, diagnostics, and platform services.
Flutter Application
├─ App Shell
├─ Material 3 / Chanora Design System
├─ Feature Modules
├─ View Models / State
└─ Typed Flutter/Rust Bridge
Rust Core
├─ Connection Manager
├─ State Synchronization
├─ Protocol Adapter
├─ Audio Subsystem
├─ Storage Services
└─ Diagnostics
Protocol Layer
└─ tsclientlib
└─ TeamSpeak-compatible server
Key architecture rules:
- Flutter does not call
tsclientlibdirectly. - Protocol-specific types do not leak into the Flutter UI layer.
- Rust Core owns protocol coordination, state synchronization, audio logic, storage services, diagnostics, and bridge-facing DTOs.
- Flutter owns presentation, navigation, Material 3 theming, accessibility, localization presentation, and platform UI behavior.
- Product localization and server-provided content are separated.
- UTF-8 is the internal cross-layer text representation.
- Non-UTF-8 conversion, if needed, occurs only at explicit protocol or platform boundaries.
MVP Direction
The current recommended MVP scope is:
| Area | MVP decision |
|---|---|
| Active server connections | One active server connection per client instance |
| UI baseline | Material 3 + Chanora Design System |
| Product language | English UI first, i18n-ready architecture |
| Server content | Preserve Unicode and do not translate server-provided content |
| Audio processing defaults | Echo Canceller, Automatic Gain Control, Noise Suppression, and High-Pass Filter enabled where supported and stable |
| Audio implementation path | Platform-native first; fallback isolated behind the audio subsystem |
| Local non-secret storage | SQLite or equivalent embedded database |
| Secret storage | Platform secure storage |
| Flutter/Rust bridge | Stable typed bridge with generated or schema-controlled DTOs |
| Diagnostics | Local, user-initiated export only |
| Telemetry | None in MVP |
| Crash reporting | Disabled unless explicitly approved later |

Engineering Process
Chanora follows this documentation hierarchy:
SysRS -> SysDes -> SRS -> SAD -> SDD
Direct traceability rules:
| Document | Direct upstream source |
|---|---|
| SysDes | SysRS |
| SRS | SysDes only |
| SAD | SRS only |
| SDD | SAD only |
Verification mapping:
SDD -> SWE.4 Unit Verification
SAD + SDD -> SWE.5 Software Integration Verification
SRS -> SWE.6 Software Verification
SysDes -> SYS.4 System Integration Verification
Release readiness is tracked separately through the Go/No-Go record.
Release Readiness
A release is not approved by design documents alone.
Before an external or public release, the project must complete:
docs/release/release-readiness-go-nogo-record.md
The release decision must explicitly state:
Go
Conditional Go
No-Go
Release readiness must include:
- release scope;
- build number;
- commit SHA;
- Git tag;
- artifact hashes;
- satisfied P0/MVP requirements;
- deferred requirements;
- verification results;
- waivers;
- security review status;
- platform readiness;
- legal and OSS review status;
- privacy policy status;
- approval decision and approvers.
Security, Privacy, and Legal Gates
Security, privacy, and legal evidence are required before public or store release.
Required documents include:
docs/security/threat-model.md
docs/security/secure-storage-audit-report.md
docs/security/diagnostic-redaction-audit-report.md
docs/security/dependency-and-supply-chain-report.md
docs/privacy/privacy-policy.md
docs/legal/trademark-and-attribution-review.md
Important gates:
- identity secrets and server passwords must use platform secure storage;
- logs and diagnostic exports must redact secrets;
- diagnostic export must be user-initiated unless a later approved policy changes this;
- dependency licenses and vulnerabilities must be reviewed;
- OSS notices must be prepared where required;
- public wording must not imply official TeamSpeak affiliation;
- privacy policy must describe local storage, diagnostics, permissions, and data handling.
Git Commit Convention
Chanora uses a Conventional Commits style format:
<type>(<scope>): <summary>
Examples:
feat(voice): add push-to-talk state handling
fix(protocol): recover channel tree after reconnect snapshot
docs(sad): add interface catalog and performance view
i18n(ui): add fallback behavior for missing localization keys
sec(diagnostics): redact server password from export bundle
release(android): prepare internal alpha build metadata
See:
docs/governance/git-commit-message-convention.md
Development
Implementation commands will be added after the repository scaffold is finalized.
Expected future commands may include:
flutter pub get
flutter test
cargo test
cargo clippy
cargo fmt
Do not treat these as authoritative until the actual Flutter/Rust workspace has been created.
Contributing
Before making a change:
- Check the affected requirement/design document.
- Confirm the correct traceability layer.
- Use the Git commit convention.
- Update docs and verification plans when the change affects requirements, architecture, detailed design, release behavior, security, privacy, or legal gates.
