It is a remediation record, **not** a `SECURITY PASS`, penetration-test certificate, or release approval. Independent dynamic/adversarial verification remains assigned to Codex after merge. + +Audit baseline SHA: `96807a39d6e18a13f1412f4425f81df595ed158f`. + +The final pre-merge CI gate requires an exact backend install/build/test/audit, Android compilation/JVM tests, and whole-tree static security invariants. Hardware-, network-adversary-, and instrumented-device checks are deferred to `CODEX_DYNAMIC_SECURITY_TEST_PLAN.md`. + +## Finding-by-finding evidence + +### RT-SEC-001 — ElectrumX TOFU certificate mismatch +**Status:** FIXED IN CODE; dynamic MITM/rotation test deferred. + +**Files:** `android/app/src/main/java/io/raventag/app/wallet/TofuTrustManager.kt`, `RavencoinPublicNode.kt`, `SubscriptionManager.kt`. + +**Invariant:** a stored certificate pin mismatch is a hard failure. The connection path cannot silently replace/re-pin a previously trusted certificate merely because a new certificate was presented. + +**Validation:** whole-tree review/static gate plus Android compile/JVM suite. Codex must exercise real first-use, unchanged cert, legitimate rotation, and active MITM cases. + +### RT-SEC-002 — Malicious relay-fee / implicit MAX transaction behavior +**Status:** FIXED AND JVM-TESTED. + +**Files:** `FeeSafetyPolicy.kt`, `RavencoinPublicNode.kt`, `RavencoinTxBuilder.kt`, `WalletManager.kt`, `SendRvnScreen.kt`, `MainActivity.kt`, `FeeSafetyPolicyTest.kt`, `RavencoinTxBuilderTest.kt`. + +**Invariant:** relay fee input is constrained by local policy; a normal send never reduces the recipient amount to make an otherwise-insolvent transaction fit. MAX is an explicit UI/application intent propagated end-to-end. + +**Validation:** fee-policy and builder regression tests; static gate rejects `isMaxSend`, legacy amount-reduction semantics, and loss of the explicit MAX parameter. Malicious live ElectrumX responses remain a dynamic Codex test. + +### RT-SEC-003 — Fail-open biometric startup authentication +**Status:** FIXED IN CODE. + +**Files:** `MainActivity.kt`, `BiometricGate.kt`. + +**Invariant:** unavailable hardware, enrollment failure, cancellation, lockout, prompt exception, and authentication error never become authenticated state. The only `authPassed=true` paths are a real authentication success and the explicitly non-secret no-wallet state. + +**Validation:** whole-tree static auth assignment gate and Android compile/JVM suite. Device-specific BiometricPrompt errors remain dynamic. + +### RT-SEC-004 — Recovery phrase not cryptographically auth-bound +**Status:** FIXED IN CODE; Android Keystore/Biometric instrumentation deferred. + +**Files:** `WalletManager.kt`, `BiometricGate.kt`, `MnemonicBackupScreen.kt`, `MnemonicExporter.kt`, `WalletManagerTest.kt`. + +**Invariant:** wallet seed/signing storage remains separate from the recovery-reveal key. Persisted mnemonic reveal uses dedicated alias `raventag_mnemonic_reveal_key_v1`, AES-GCM, and Android Keystore `setUserAuthenticationRequired(true)`. API 30+ uses `AUTH_BIOMETRIC_STRONG | AUTH_DEVICE_CREDENTIAL`; API 26-29 uses the authentication-validity compatibility API. There is no production general-wallet-key `getMnemonic()` bypass. + +**Migration invariant:** authenticate first; decrypt and integrity-check the legacy mnemonic; encrypt with the auth-bound key; locally verify; persist; read back and decrypt the persisted copy; only then remove legacy mnemonic ciphertext/IV/integrity tag. If interrupted after verified persistence but before cleanup, the next successful auth-bound reveal verifies the new copy and completes cleanup. Errors fail closed and retain the legacy copy. + +**Validation:** compile/static assertions verify the dedicated auth-required key and absence of a bypass. Real Keystore user-auth enforcement, cancellation, key invalidation, reboot/timeout, and migration on physical/emulated Android are explicitly deferred to Codex. + +### RT-SEC-005 — Legacy plaintext secret persistence +**Status:** FIXED AND JVM-TESTED. + +**Files:** `MainActivity.kt`, `security/LegacySecretMigration.kt`, `LegacySecretMigrationTest.kt`, `AdminKeyStorage.kt`. + +**Invariant:** new application secrets are stored in `raventag_secure_v2` (`EncryptedSharedPreferences`) or the dedicated encrypted `AdminKeyStorage`. Only the historically secret-bearing keys `admin_key`, `operator_key`, `initial_master_key`, and `pinata_jwt` are migrated from legacy `raventag_secure`. `kubo_node_url` is non-secret configuration and is moved to normal application preferences rather than included in the secret whitelist. + +**Migration invariant:** source is removed only after encrypted destination write and read-back equality. Secure-store failure leaves source untouched. A run interrupted after destination verification but before deletion is safely resumable. + +**Validation:** JVM tests cover no legacy values, successful migration, encrypted-store failure, interrupted migration, and repeated/idempotent migration. Final CI statically rejects new duplicate admin/Kubo writes into secret storage. Real upgrade tests remain in the Codex plan. + +### RT-SEC-006 — Insufficient Ravencoin address validation +**Status:** FIXED AND JVM-TESTED. + +**Files:** `RavencoinTxBuilder.kt`, `RavencoinTxBuilderTest.kt`. + +**Invariant:** Base58Check checksum, payload structure, canonical encoding, and Ravencoin mainnet P2PKH version `0x3C` are enforced before transaction construction. Foreign-network Bitcoin-style addresses are rejected. + +**Validation:** address regression vector plus final static invariant. + +### RT-SEC-007 — Registry poisoning with unrelated valid txid +**Status:** FIXED AND BACKEND-TESTED. + +**Files:** `backend/src/routes/registry.ts`, `services/registry-issuance.ts`, `services/registry-issuance.test.ts`, `services/ravencoin.ts`. + +**Invariant:** registry claims are accepted only when `getrawtransaction(..., true)` semantics prove the transaction actually creates the claimed Ravencoin asset with matching issuance type/name, required canonical burn, and owner-token semantics where applicable. + +**Validation:** backend tests cover canonical root issuance, ordinary/unrelated tx rejection, asset-name mismatch, type mismatch, missing burn, missing owner token, and valid unique issuance. Real mainnet transaction corpus is deferred to Codex. + +### RT-SEC-008 — Concurrent UTXO spend race / reservation after signing +**Status:** FIXED IN CODE AND REGRESSION-GATED. + +**Files:** `WalletManager.kt`, `cache/ReservedUtxoDao.kt`, transaction tests. + +**Invariant:** every on-device financial signing path enters a shared signing mutex and obtains durable `CONFLICT_ABORT` reservations before any transaction builder/signature invocation. The reservation is rebound to the locally computed txid before network I/O; post-sign ambiguous network failure retains the reservation. + +**Validation:** Android compile/JVM suite and whole-tree gate reject direct `tx.hex` broadcast bypasses and require reservation-before-build ordering. True simultaneous coroutine/process/device stress is deferred to Codex. + +### RT-SEC-009 — Mnemonic clipboard exposure +**Status:** FIXED IN CODE. + +**Files:** `MnemonicBackupScreen.kt`, `MnemonicExporter.kt`. + +**Invariant:** no Copy All/clipboard operation exists for the recovery phrase; sensitive buffers are held as `CharArray` where practical and cleared on disposal. `FLAG_SECURE` protects the display. + +**Validation:** final static gate scans the mnemonic reveal components for clipboard APIs. + +### RT-SEC-010 — Mutable CI/action/container supply-chain references +**Status:** FIXED IN REPOSITORY WORKFLOWS. + +**Files:** `.github/workflows/qwen-dispatch.yml`, `qwen-invoke.yml`, `qwen-review.yml`, `qwen-scheduled-triage.yml`, `qwen-triage.yml`. + +**Invariant:** Qwen code actions are immutable commit-SHA references and security-sensitive Qwen/MCP containers use immutable digests; unnecessary OIDC permission was removed. + +**Validation:** final whole-tree workflow scan rejects mutable Qwen action/container references. + +### RT-SEC-011 — NFC replay counter race +**Status:** FIXED LATO CODICE; deployment topology must preserve single authoritative replay state or equivalent serialization. + +**Files:** `backend/src/middleware/cache.ts` and NFC verification path. + +**Invariant:** replay counter compare/update is atomic at the database boundary rather than a separate check-then-write race. + +**Validation:** static/backend tests where available. Multi-instance contention and real-tag replay remain dynamic/operational tests. + +### RT-SEC-012 — Android global cleartext networking +**Status:** FIXED. + +**Files:** `AndroidManifest.xml`, `res/xml/network_security_config.xml`. + +**Invariant:** cleartext traffic is denied globally; there is no global cleartext exception. + +**Validation:** final static gate. + +### RT-SEC-013 — `/verify` deep-link host trust +**Status:** FIXED. + +**Files:** `NfcReader.kt`, Android manifest/app-link configuration. + +**Invariant:** `/verify` is accepted only from the explicit RavenTag authorized host set, not merely by matching a path on an arbitrary HTTPS host. + +**Validation:** static/JVM validation; malicious real intents remain in Codex plan. + +### RT-SEC-014 — Unchecked NDEF payload indexing +**Status:** FIXED. + +**Files:** `NfcReader.kt`. + +**Invariant:** NDEF payload parsing checks length/structure before indexing; no unchecked `payload[0]` path remains. + +**Validation:** final static gate and Android JVM suite. + +### RT-SEC-015 — IPFS redirect policy bypass +**Status:** FIXED. + +**Files:** `backend/src/services/ipfs.ts`, Android `RpcClient.kt`/IPFS client path. + +**Invariant:** validation is not bypassed by transparent HTTP/HTTPS redirect following; redirect targets must not silently escape the intended policy. + +**Validation:** static gate requires redirect following disabled on the relevant client. Malicious redirect chains remain a Codex test. + +### RT-SEC-016 — Backend dependency advisories +**Status:** FIXED BY COMPATIBLE DEPENDENCY REFRESH; final gate requires zero npm audit findings at low-or-higher severity. + +**Files:** `backend/package.json`, `backend/package-lock.json`. + +**Pre-refresh exact audit:** 9 vulnerabilities: 4 high, 4 moderate, 1 low. + +- `form-data` (direct, high, GHSA-hmw2-7cc7-3qxx): multipart CRLF injection; backend IPFS multipart code makes this relevant. Fixed by `4.0.6`. +- `multer` (direct, high): nested-field DoS and aborted-upload cleanup advisories; source import was not found in the current backend, reducing present reachability, but the declared dependency is updated to `2.2.0` rather than relying on non-use. +- `express` (direct, moderate): affected through vulnerable `qs`; request routing/parsing is network reachable. Updated within major 4 to `4.22.2`. +- `express-rate-limit` (direct, moderate): affected through `ip-address`; rate-limit middleware is on public/admin request paths. Updated within major 8 to `8.6.2`. +- `body-parser` (transitive, moderate aggregate): reachable through Express JSON request parsing; fixed by dependency refresh. +- `qs` (transitive, moderate): Express/body-parser dependency; fixed by Express dependency refresh. +- `path-to-regexp` (transitive, high): Express routing dependency; fixed by Express dependency refresh. +- `ip-address` (transitive, high aggregate): express-rate-limit dependency; fixed by express-rate-limit dependency refresh. +- `esbuild` (transitive, low): pulled through `tsx`, used for dev/test tooling rather than production server runtime; fixed by updating `tsx` within major 4. + +`axios` is also refreshed within major 1. No `npm audit fix --force` is used. The final gate executes `npm ci`, TypeScript build, backend tests, and `npm audit --audit-level=low`; merge is blocked if any advisory remains. + +### RT-SEC-017 — Default-branch governance +**Status:** OPERATIONAL REMEDIATION REQUIRED. + +**Evidence:** remote `master` branch protection/ruleset is not enabled and the available repository connector does not expose an authorized branch-protection/ruleset mutation in this workflow. + +**Required operator action:** enable branch protection/ruleset for `master` (PR requirement, required status checks including the permanent security gate, restrict force-push/deletion, appropriate review policy). + +### RT-SEC-018 — Committed Android local SDK path +**Status:** FIXED. + +**Files:** `.gitignore`; `android/app/local.properties` removed from the tracked tree. + +**Invariant:** machine-local Android SDK paths are not repository content. + +**Validation:** final secret/dangerous-pattern gate rejects tracked `local.properties`/signing/environment files. + +### RT-SEC-019 — BIP39 normalization/KDF compatibility +**Status:** FIXED AND JVM-TESTED. + +**Files:** `Bip39Kdf.kt`, `Bip39KdfTest.kt`, `WalletManager.kt`. + +**Invariant:** mnemonic/passphrase inputs use BIP39 NFKD normalization and production seed derivation delegates to the same vector-tested implementation. + +**Validation:** official BIP39 vector and Unicode normalization-equivalence JVM tests. Full BIP32/BIP44/transaction vector corpus remains in Codex plan. + +### RT-SEC-020 — Backup key separation / retention +**Status:** FIXED IN CODE AND DEPLOYMENT CONFIG. + +**Files:** `backend/src/services/backup.ts`, `backend/src/index.ts`, `docker-compose.yml`, `.env.example`, `docs/deploy/en.md`. + +**Invariant:** backup interval is 24 hours and retention is 7 encrypted snapshots. Backup encryption material is a dedicated `backup_encryption_key` / `INTERNAL_BACKUP_ENCRYPTION_KEY_FILE`, never `ADMIN_KEY`/`ADMIN_KEY_FILE`. The in-process scheduler is opt-in and fails closed when enabled without its dedicated key path. Compose mounts admin auth and backup encryption as different secrets; documentation explicitly forbids key reuse. + +**Validation:** final whole-tree gate asserts interval/retention and distinct paths, then performs global secret-name review. + +## Validation executed by the final gate + +The merge gate runs on the exact PR HEAD: + +```text +backend: + npm ci --ignore-scripts + npm run build + npm test + npm audit --audit-level=low + +android: + ./gradlew compileBrandDebugKotlin compileConsumerDebugKotlin + ./gradlew test + +repository: + whole-tree security invariant assertions + immutable Qwen/MCP reference assertions + tracked-secret/dangerous-pattern scan + git diff --check +``` + +A green gate proves only these automated checks.

Android biometric failure states +On representative API 26-29 and API 30+ devices/emulators: +- no biometric/credential enrollment; +- user cancel / negative button; +- repeated failed biometric; +- temporary/permanent lockout; +- prompt initialization exception/pathological lifecycle change; +- app background/foreground and rotation during prompt. +No state may become authenticated on an error path. + +## 4. Real auth-bound Android Keystore recovery reveal +- Inspect generated alias `raventag_mnemonic_reveal_key_v1` and prove user authentication is required by KeyInfo/runtime behavior. +- Attempt direct decrypt before authentication: must fail. +- Authenticate and decrypt within validity window: succeeds. +- Wait beyond validity window: decrypt must fail again until re-authentication. +- Test device reboot/lock and biometric enrollment changes/key invalidation behavior. +- Verify normal seed/signing operations remain independent and do not require the recovery-reveal key. +- Confirm no alternate production method can recover mnemonic plaintext through the general wallet key. + +## 5. Legacy wallet mnemonic migration +Create an installation containing only the pre-remediation mnemonic ciphertext/IV/HMAC and a valid wallet seed. +- Cancel authentication: legacy remains untouched; no new representation considered complete. +- Force failure during new-key creation/encryption: legacy remains. +- Force failure after new encryption but before persistence: legacy remains. +- Force process death after new persistent copy but before legacy deletion; restart and repeat reveal: new copy must decrypt and cleanup must finish safely. +- Verify migrated phrase exactly matches original and derives the same BIP39 seed/BIP44 addresses. +- Repeat migration/reveal multiple times; result is idempotent. + +## 6. Legacy `raventag_secure` secret migration +Test both historical layouts: +- ordinary plaintext `SharedPreferences` file; +- v1 `EncryptedSharedPreferences` file. +For `admin_key`, `operator_key`, `initial_master_key`, and `pinata_jwt`: +- no legacy values -> no-op; +- valid values -> v2 encrypted/dedicated storage, read-back equality, then legacy deletion; +- unavailable/corrupt Keystore -> sensitive features blocked and legacy remains untouched; +- kill process after destination write but before source deletion -> repeat safely finishes cleanup; +- repeated migration -> no duplicate/destructive behavior. +Confirm `kubo_node_url` is handled as non-secret configuration rather than indiscriminately included in the secret whitelist. + +## 7. Simultaneous UTXO spend attempts +- Launch two or more sends/transfers/issuances/sweeps concurrently against overlapping UTXOs. +- Prove only one operation reserves an outpoint and the losing operation never signs. +- Inject crash after reservation/before signing: safe release/recovery behavior. +- Inject timeout/drop after signing/before/after broadcast response: reservation remains until reconciliation proves safe release. +- Verify no direct builder/broadcast entrypoint bypasses the common boundary. + +## 8. Registry validation with real Ravencoin transactions +Use known real transactions for: +- valid root issuance; +- valid sub-asset issuance; +- valid unique issuance; +- ordinary payment txid; +- issuance of a different asset name; +- wrong claimed issuance type; +- missing/wrong canonical burn; +- owner-token semantic mismatch; +- malformed/unavailable RPC response. +Only semantically matching issuance claims may enter the registry. + +## 9. NTAG424 / NDEF / replay +With real NTAG424 DNA hardware and malformed synthetic NDEF records: +- valid SUN CMAC/counter progression; +- repeated counter/replay; +- out-of-order/racing scans; +- malformed/zero-length payloads; +- unsupported URI prefix codes and truncated records; +- tag clone attempts; +- concurrent backend verification requests for the same counter. +Verify no crash and no replay acceptance. + +## 10. IPFS redirect/adversarial fetches +- 301/302/307/308 from an allowed gateway to disallowed HTTP/HTTPS/private/link-local destinations. +- redirect loops and long chains; +- DNS rebinding where feasible; +- oversized/slow responses. +Transparent redirects must not bypass endpoint validation. + +## 11. Android cleartext and deep-link behavior +- Attempt HTTP connections from each app flavor: globally denied unless an intentionally scoped exception is documented (none expected). +- Send ACTION_VIEW `/verify` links from every authorized production host: accepted. +- Same `/verify` path from attacker-controlled HTTPS hosts, subdomain lookalikes, Unicode/punycode variants, explicit ports, userinfo URLs: rejected. + +## 12. Backend dependency/runtime checks +- Re-run `npm ci` and `npm audit --audit-level=low` from a clean clone of the merged SHA. +- Exercise upload/IPFS, Express JSON parsing/routing, and rate-limit paths after dependency upgrades. +- Confirm no behavioral regression from Express 4.22.2, express-rate-limit 8.6.2, form-data 4.0.6, multer 2.2.0, tsx 4.23.12, and the final Axios 1.x pin. + +## 13. BIP39/BIP32/BIP44 and transaction vectors +- Official BIP39 English vectors including passphrases and NFKD Unicode equivalence. +- BIP32 derivation vectors for hardened/non-hardened descendants where applicable. +- Ravencoin BIP44 coin type 175 addresses for known mnemonic fixtures. +- Base58Check valid/invalid checksum, foreign-network version bytes, non-canonical encodings. +- Known-good RVN transaction serialization/signature vectors for normal send, MAX, asset transfer, issuance, reissue, and sweep. + +## Exit criteria +For every scenario capture PASS/FAIL, exact reproduction steps, raw logs/pcaps/transactions where applicable, and the tested commit SHA. Any exploitable bypass, unexpected fail-open behavior, incorrect transaction semantics, or wallet-data-loss condition reopens the corresponding RT-SEC finding.
