EdisonJwa 0f418f1d7e feat(legal): resolve DEC-020 — dual-license under Apache-2.0 OR MIT 
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.

Decision register state after this commit:
  Accepted:       23 of 23 unique decisions
  Open/Deferred:  0
  Proposed:       0

  • poc/sqlite-storage-spike/ — PoC proving SRS-089's "embedded data store + migration mechanism" acceptance criteria: forward-only schema migrator tracked via PRAGMA user_version, repository pattern with BookmarkRepository / SettingsRepository traits over LocalDatabaseRepository. 11/11 tests verified on 2026-05-13.
  • poc/diagnostics-redaction-spike/ — PoC proving the diagnostic redaction policy from diagnostic-redaction-audit-report.md: typed policy + regex rules + literal known-secret registry + bundle redaction. Audit cases REDACT-TC-001..010 verified on 2026-05-13.

  • poc/README.md summarising PoC status against docs/architecture/proof-of-concept-plan.md.

Changed

  • DEC-020 license resolved. Chanora is now dual-licensed under Apache-2.0 OR MIT (recipient's choice), the standard Rust-ecosystem permissive model. Compatible with every direct dependency (tsclientlib, flutter_rust_bridge, cpal, rusqlite, keyring, etc.) and with the Flutter framework's BSD-3-Clause. LICENSE rewritten as a dual-license aggregator pointing at LICENSE-APACHE and LICENSE-MIT. NOTICE rewritten with current direct-dependency attributions. README.md §License updated.

  • docs/governance/product-decision-register.md bumped to v0.9.6: DEC-020 status promoted from Open to Accepted. §4 license row updated. §6 collapsed: there is no longer any open decision — DEC-012 legal review remains as a work item, not a pending decision. Change-history entry added.

  • docs/governance/poc-results-summary.md bumped to v0.4.0: RISK-PoC-003 closed. DEC-020 row moved from the "Still open" section into the closed table.

  • docs/governance/product-decision-register.md bumped to v0.9.5: owner confirmation on all 17 previously-Proposed decisions (DEC-001..010, 012, 015..019, 021). Sixteen were Accepted as recommended; two were modified by the owner — DEC-004 Android minimum raised from API 24 to API 28, and DEC-015 product language for MVP expanded from English-only to English + Chinese (Simplified). DEC-020 license remains Open / Deferred and is now the only public-release-gating decision outstanding. §4 renamed "Recommended" → "Accepted MVP Defaults" with MODIFIED rows annotated. §6 collapsed to the single remaining DEC-020 item. §7 dated and statused for every decision.

  • docs/governance/poc-results-summary.md bumped to v0.3.0: RISK-PoC-004 closed by the owner-confirmation pass; new RISK-PoC-006 (Android minSdk move 24 → 28 for product code) and RISK-PoC-007 (MVP language expansion to en + zh-Hans) added.

  • docs/architecture/proof-of-concept-plan.md bumped to v0.3.0 to promote the audio PoC from PARTIAL PASS to PASS after the Android mobile half was closed; all six PoC plan entries are now PASS.

  • docs/governance/product-decision-register.md bumped to v0.9.4 to promote DEC-011.1 mobile half from Deferred to Accepted (Android), keeping iOS Deferred.

  • docs/governance/poc-results-summary.md bumped to v0.2.0: audio row promoted to PASS, RISK-PoC-001 narrowed from "mobile audio" to "iOS audio only", Android toolchain added to the toolchain table.

  • poc/audio-capture-playback-spike/VERIFICATION.md updated to point at the Android spike for the mobile half.

  • poc/README.md updated to list both audio spike directories.

  • docs/architecture/proof-of-concept-plan.md bumped to v0.2.0 to record PoC outcomes (5 PASS, 1 PARTIAL) and add a Status column.

  • docs/security/secure-storage-audit-report.md bumped to v0.9.3: SS-AUD-001/002/003/005/006 status set to PoC Pass with evidence pointers; SS-TC-003 (Linux) Actual Result populated and Status set to PoC Pass; findings SS-FIND-001..003 added; non-Linux test cases marked Deferred.

  • docs/security/diagnostic-redaction-audit-report.md bumped to v0.9.3: REDACT-TC-001..010 status set to PoC Pass with evidence pointers; export bundle policy §5 populated; findings REDACT-FIND-001..003 added.

  • docs/governance/product-decision-register.md bumped to v0.9.3: owner-confirmed decisions recorded — DEC-014 Accepted (flutter_rust_bridge 2.x pinned), DEC-013.1 Accepted (rusqlite bundled), DEC-013.2 Accepted (Linux Secret Service preferred, keyutils fallback), DEC-011.1 Accepted (desktop cpal) / Deferred (mobile), DEC-022 Accepted (canonical implementation directory layout per README sketch + SAD §7.2), DEC-020 explicitly Deferred and remains a public-release blocker.

Added (governance)

  • docs/governance/poc-results-summary.md v0.1.0 — single-page reviewer-facing summary of the PoC phase, the toolchain exercised, the owner decisions taken, the audit coverage, and the open risks RISK-PoC-001..005.
