+## TEESimulator-RS v6.0.1-282
+
+AUTO-mode key attestation now forges plain attestation from the keybox instead of deferring to the real TEE.
+
+### Detection coverage
+- AUTO dispatch probed the device with `checkTeeFunctionality`, which only proves the TEE can mint one EC key. It says nothing about RSA attestation, device-ID attestation, or whether a patched chain survives RSA verify. Plain attestation requests (attest-key OFF, challenge present) were routed to PATCH and deferred to hardware, so devices that can't back that surfaced KeyAttestation reds: `ATTESTATION_KEYS_NOT_PROVISIONED` (-49) and `BLOCK_TYPE_IS_NOT_01`.
+- AUTO targets carrying an attestation challenge now take the FORGE path, the same one attest-key-ON already used: a synthetic chain built from the keybox and rooted under the Google root key. Requests with no challenge still pass through to real hardware, so KeyDetector's hardware-backed checks are unaffected.
+
+### Verified
+- Offline conformance against real FORGE captures: uid10389 and uid10154 chains are GREEN; the root SPKI byte-matches `GOOGLE_ROOT_PUBLIC_KEY`.
+
+---
+
+## TEESimulator-RS v6.0.1-280
+
+Clears the Duck Detector generate-mode parcel fingerprint that real Android 16 hardware also trips, fixes RSA attestation under an EC-only keybox, and restores device-property attestation for Play Integrity hardware apps such as BHIM and UPI. Generate-mode fix field-confirmed on Android 16.
+
+### Detection coverage
+- Generate-mode fingerprint: Duck reads the reply at a flat 12-byte stride and flags the sentinel tuple at positions 12 and 13 that the device's native ALGORITHM-first authorization order lands on. Real A16 silicon trips the same probe, so faithful mirroring stayed flagged. `normalizeAuthorizationLayout` marshals the auth array, runs Duck's exact predicate, and applies a minimal deterministic reorder only when it would match. Count, values, security levels, and the cert chain are untouched, and the reorder keys on the byte condition, never on a package. Applied on both the patch and forge reply paths. (#33)
+- `updateAad` on a non-AEAD operation now answers per vendor: Samsung and Xiaomi-MTK TEEs return success, others return INVALID_TAG, matching Duck's OperationErrorPathProbe on both the sign/verify and cipher paths.
+
+### Attestation correctness (Android 16, EC and RSA)
+- RSA leaf under an EC-only keybox: patching used to catch the no-RSA-key throw and return the chain untouched, leaking the device's real unlocked Root of Trust for RSA keys while EC keys patched cleanly. It now falls back to any keybox key (EC preferred) and signs the patched leaf with the keybox key's own algorithm, so the RSA leaf re-roots to the Google keybox under a forged locked RoT.
+- RSA attest-key forge on an EC-only keybox: the forge path matched the algorithm exactly and threw -75 ATTESTATION_KEYS_NOT_PROVISIONED on a miss, so an RSA ATTEST_KEY request never rooted and verifiers reported an unknown certificate. It now falls back to any attestation key, since an EC key validly ECDSA-signs an RSA-subject leaf. No-op on a dual keybox.
+- A16 attestVersion: the device's KeyMint reports version 100 and the lazy cache shadowed the BAKLAVA-to-400 map, so the forge presented 100. It now caches the AOSP value per SDK and presents the correct 400.
+- Algorithm-split key on restore: a persisted record holding an EC private key under an RSA leaf failed every signature as DATA_TOO_LARGE_FOR_MODULUS. Restore now drops the record when the private key and served leaf disagree, so the next generateKey rebuilds a coherent key.
+- Stale chain on regenerate: reusing an alias in generateKey now evicts the cached chain, matching keystore2, so getKeyEntry serves the current key instead of a stale forge from an earlier generation.
+
+### App compatibility
+- Device-property attestation (BRAND, MODEL, and the rest) now forges unconditionally. The old gate probed the live TEE, which is dead on every device the module serves, so it rejected GMS Play Integrity's hardware path and broke BHIM and other UPI and Play-Integrity apps. Device-ID attestation (IMEI, serial) stays governed by the real KeyMint caller-permission rule: privileged callers get it, ordinary apps do not.
+- getKeyEntry now reaches the owned-key lookup for skipped privileged UIDs, so framework attestKeyAlias resolution no longer returns "Invalid attestKeyAlias" for Key Attestation over Shizuku. Non-owned keys still skip post-processing, so a real app's key is never patched.
+- Device-ID attestation over Shizuku (a privileged UID absent from target.txt) now takes the forge path instead of hitting the real TEE's CANNOT_ATTEST_IDS (-66). "Use attest key" no longer double-roots: a reused persistent attest key is resolved by KEY_ID as well as alias, and an unresolved designated attest key refuses to emit a leaf rather than silently re-rooting under the keybox.
+
+### Diagnostics (debug builds only)
+- Per-UID attestation dossier for targeted UIDs at /data/local/tmp/teesim/, recording the decoded chain on both forge and patch paths, key params, the keybox pick (including EC fail-safe), prop sources, forge failures, the emitted authorization shape, and served-versus-verified chains. Release builds strip this through R8 and stay silent. Keybox certificate serials log on every fetch for revocation triage.
+
+### Verified
+- Android 16: generate-mode fingerprint signal gone, confirmed on device 2026-06-19.
+
+---
+
+## TEESimulator-RS v6.0.1-251
+
+14 commits since v6.0.0-235. Clears the remaining Duck Detector grant-domain rows (incl. the Android 16 OnePlus report), restores Google Wallet and fingerprint compatibility, and removes the in-module patch-level/bulletin resolvers. Test device (SDK 35) TEE tamper score 28 → 8.
+
+### Detection coverage
+- Grant plane virtualized: owner read and cross-app `Domain.GRANT` read return one identical chain. 6 RED rows cleared. (28 → 18)
+- Generate-mode fingerprint: dropped 2 surplus authorizations (both patchlevels), USER_ID moved to SOFTWARE to mirror a captured device. (18 → 8)
+- Android 16 grant: patch-mode keys now served on the grant plane, so owner and grant reads match — fixes CHAIN_SPLIT.
+- Grant gated to SDK ≥ 36: Android 15 answers PERMISSION_DENIED, no synthetic over-capability.
+- Stale-chain eviction: import and updateSubcomponent drop the cached attestation; no pre-mutation chain replays.
+- Lifecycle coherence: clearNamespace / deleteAllKeys / migrateKeyNamespace mirror synthetic key and grant state — defeats delete-then-read probes.
+- Device-ID attestation mirrors the real TEE: returns CANNOT_ATTEST_IDS where silicon can't attest, instead of forging it.
+
+### App compatibility
+- Google Wallet: INCLUDE_UNIQUE_ID stripped (not rejected) when the caller lacks the permission; card binding works. (PR #27)
+- Fingerprint / vendor keys: KEY_ID miss skips the post-handler, so real HAL operations are no longer wrapped and broken. (PR #26)
+
+### Removed
+- PatchLevelManager — auto-resolved the security-patch date from an installed PlayIntegrityFix module (with hot-reload) and applied it to props.
+- BulletinPoller — scheduled security-bulletin refresh.
+
+### Other
+- Release builds purge stale `teesim-*.bin` diagnostics from `/data/local/tmp` at boot.
+- Vol-key confirmation rewritten to 1s `getevent` bursts (piped stream missed single presses on Magisk).
+
+### Verified
+- SDK 35, Xiaomi 23106RN0DA: tamper 28 → 8; generate-mode signal gone; 4 grant rows UNAVAILABLE (correct for Android 15); no regressions.
+- Android 16 grant fix built but unconfirmed on SDK 36 — needs an affected OnePlus user to confirm the grant rows clear.
+
+---
+
+## TEESimulator-RS v6.0.0-235
+
+11 commits since v6.0.0-224. Duck Detector generate-mode fingerprint cleared. Shizuku-routed BYO attestation fixed. Vol-key confirmation restored on Magisk.
+
+### Detection Coverage
+- Duck Detector "TEE Simulator generate-mode fingerprint" cleared. `toAuthorizations` reordered to AOSP keymint reference order; KEY_SIZE moves from auth#4 to auth#2, breaking the byte-224 anchor the probe relied on. 0/31 matches on fresh self-probes (was 15/36).
+- `persist.logd.size` variants blanked at boot via `service.sh`. Removes a logd-tuning side-channel.
+
+### BYO & Shizuku Routing
+- Shizuku-routed BYO attestation no longer fails with `-49 UNSUPPORTED_TAG`. `shouldSkipUid` moved into `handleGenerateKey`, evaluated after BYO parameters are parsed.
+- `createOperation` parallel fix: outer UID gate removed; the cache-or-forward lookup is the sole gate. BYO keys created under Shizuku UID can now be used for signing under the same UID.
+- `forceGenerate` simplified: any attest-key or BYO request routes to software unconditionally.
+- BYO attest-key miss returns the full keybox chain instead of a malformed depth-1 chain.
+- AUTO TEE race dispatch removed. Resolution uses `DeviceAttestationService.isTeeFunctional` only.
+- Symmetric gen rejects `attestationKey != null` early with `INVALID_ARGUMENT`. Unsupported-algorithm branch returns `-38` instead of `-49`.
+
+### Action Button
+- Vol+ / Vol- confirmation restored on Magisk. Streaming `getevent -lq` matched inline against `KEY_VOLUMEUP DOWN` / `KEY_VOLUMEDOWN DOWN`, wrapped in `/system/bin/timeout 10`. The prior polled approach timed out on six-events-per-keypress kernels.
+
+### Verified
+- Android 15 (SDK 35), daemon PID 1466.
+- Cross-device confirmation pending on OnePlus PKX110 and Samsung SM-S928B.
+
+---
+
+## TEESimulator-RS v6.0.0-224
+
+59 commits since v6.0.0-162. Self-sufficient spoofing infrastructure, Duck Detector TamperScore-4 cleared on Xiaomi A16, persistent symmetric key storage (PR #22), 22-language action button hardening.
+
+### Detection Coverage
+- Duck Detector TimingSideChannelProbe cleared on Xiaomi A16 (SDK 35). Timing ratio dropped 1.555x to 1.055x, verdict WARNING to CLEAR. Threshold is > 1.1x.
+- `KEY_ID` resolved from `teeResponses` instead of synthesized, matching real KeyMint binder behavior.
+- Non-attested key cache mirrors attested path for byte-level metadata parity.
+- `KEY_SIZE` emitted for EC keys; omitted when `ecCurve` is present, matching AOSP attestation_record.h.
+- SSE messages synthesized canonically on non-AEAD `updateAad`; passthrough shape normalized.
+- StrongBox attest version no longer hardcoded; resolved from device context.
+- TEE op latency floor enforced to defeat micro-timing probes.
+- Attest key resolution restored to nspace-aware lookup after revert/restore cycle.
+
+### Self-Sufficient Spoofing
+- `PatchLevelManager` resolves OS/VENDOR/BOOT patch levels via PIF without external bulletin fetch.
+- `BulletinPoller` refreshes bulletin data on a schedule, isolated from boot path via umbrella `try/catch`.
+- Bootloader-lock props pushed via `resetprop` at boot; absent vbmeta complement props filled; `vbmeta.device_state` included.
+- PIF hot-reload via `FileObserver`; empty source files skipped; future patch dates bounded by `MAX_FUTURE_DAYS`.
+- Default `security_patch.txt` dropped at install time.
+- `sepolicy.rule` allows UDP egress for DNS resolution.
+
+### Key Persistence (PR #22)
+- Symmetric keys persist across reboots with byte-identical metadata.
+- Keybox edits no longer wipe stored keys.
+- Delete marker dropped on key regeneration to prevent stale state.
+- Defensive symmetric fallback path with clean error codes.
+
+### Reliability
+- `atomicWrite` preserves `[pkg]` sections; errors guarded in `updateTo`.
+- `applyToProps` serialized against concurrent callers.
+- `pollOnce` wrapped in umbrella `try/catch`; `BulletinPoller.start` failure isolated from spoofer init.
+- Spoofer ordering fixed: runs before keystore hook to prevent attest-time prop drift.
+- `isAutoMode` reads raw package mode; `system=prop` passive default respected.
+- `mergedContents` propagates read errors instead of swallowing them.
+- Date regex validation on `currentPatch`; YYYY-MM input skips day synthesis.
+- Global key-assignment check requires `=` delimiter (no more partial matches).
+- `validation_rejected` status emitted on invalid spoof input.
+
+### Action Button UX
+- Vol+ required to clear `persistent_keys`. Vol- cancels. 10-second timeout defaults to cancel.
+- Confirmation localized in 22 languages: ar, az, bn, de, el, es-ES, fa, fr, id, it, ja, ko, pl, pt-BR, ru, th, tl, tr, uk, vi, zh-CN, zh-TW.
+- Every echoed string resolves through `_msg()` against device locale.
+
+### Build & Ops
+- Kotlin `jvmTarget` raised to JVM 21.
+- Gradle auto-rewrites `module/update.json` on packaging.
+- `scripts/package.sh` locates user-local cargo; rust task receives cargo bin path.
+- Verified on Xiaomi Android 16 (SDK 35) `v6.0.0-224-Release`. Daemon alive PID 1392. Pending cross-device confirm on OnePlus PKX110 (qcom sun) and Samsung SM-S928B (pineapple).
