Subject: [PATCH 01/10] Improve Keycard benchmark verification and test

Use the card's extended-key API and robust local verification when benchmarking Keycard/Satochip signing, plus add a standalone test script.

- _keycard_benchmark_pubkey: switch to using card_bip32_get_extendedkey at the leaf path and return an embit PublicKey parsed from the card key bytes (matches Satochip signing behavior).
- _verify_der_signature: refactor to try the cryptography library first, fall back to pycryptodomex, normalize/handle DER as needed, and log failures. This provides more reliable ECDSA verification across environments.
- Benchmark views (ToolsKeycardBenchmarkSignView / ToolsKeycardBenchmarkMessageSignView): obtain per-leaf pubkeys for best-effort verification, do not abort the benchmark on mismatches (just record whether signatures verified), set connector._last_path for 0xFF routing, and improve logging/messages.
- Minor import adjustments and add GenericStaticQrEncoder import used in Satochip export QR view.
- Add tools/test_keycard_benchmark.py: standalone script to connect to a Keycard, sign a deterministic hash, and exercise multiple DER parsing/verification methods (secp256k1, embit, cryptography, ecdsa) to aid debugging of DER/signature issues.

These changes improve the fidelity of benchmark verification (verifying against the same key the card uses), make verification resilient across different verification backends, and add a developer tool for reproducing and diagnosing signature/DER problems.

Subject: [PATCH 02/10] Tolerate non-canonical DER and use digit keyboard

Monkey-patch keycard-py signing to accept non-minimal DER integer encodings (strip leading zero padding) by injecting a tolerant DER parser and replacing the sign() implementation at import time. Also coerce signature_der to bytes and attempt to normalize DER via seedsigner.helpers.satochip_signer when available to avoid UnexpectedDER errors. Additionally, default several PIN/PUK/passphrase prompts to the digits-only keyboard (SeedAddPassphraseScreen.KEYBOARD__DIGITS_BUTTON_TEXT) so PIN/PUK entry is easier and less error-prone in the smartcard views.

Subject: [PATCH 03/10] Add keyboard text and kwargs to FakePrompt

Update multiple FakePrompt classes in tests/test_javacard_mnemonic_tools.py to define KEYBOARD__DIGITS_BUTTON_TEXT and accept **kwargs in __init__. This makes the fake prompts match the real prompt interface (preventing missing-attribute or unexpected-argument errors) across several tests and the _run_prompt_with_responses helper.

Subject: [PATCH 04/10] Initialize passphrase keyboard from initial state

SeedAddPassphraseScreen._run now sets cur_keyboard and button labels based on self.initial_keyboard (uppercase, digits, symbols_1, symbols_2), matching the _render logic. This ensures the interactive passphrase entry starts with the same keyboard layout shown initially and avoids UI/state mismatches; falls back to the default abc keyboard when no initial keyboard is specified.

Subject: [PATCH 07/10] Return SignResult and add signing timeout retry

Introduce a SignResult dataclass and update card signing APIs to return it (signed_count, timed_out). sign_psbt_with_satochip and sign_psbt_with_keycard now accept an optional timeout override and report whether a TimeoutError occurred. PSBTFinalizeView consumes the new result, logs timed_out state, and prompts the user to retry with an increased timeout when a card signing timeout happens (tracking a per-controller retry timeout).

Also: adjust keycard timeout choices (granularity, min/max/default) in settings, fix several import issues after splitting tools_views (add missing pysatochip JCconstants imports in gpg_views and smartcard_views, import ToolsCommonFilterScreen), improve SeedKeeper init error message, ensure loading_screen is stopped safely on exception, and remove Javacard mnemonic menu entries and related tests. Add new tests to validate module-level imports and update existing signing tests to expect SignResult.

Subject: [PATCH 08/10] Handle stale keycard pref for SeedKeeper flows

Avoid crashing when a stale backend_preference='keycard' is present for SeedKeeper/card filters that are not satochip. _init_card_connector now logs the incompatibility and falls back to auto (using the legacy connector) instead of raising an exception; it still uses the keycard connector when the card_filter is ['satochip']. Views were updated to explicitly set smartcard_backend_preference to 'pysatochip' for SeedKeeper, Satochip, Satochip-DIY and common/tools that require pysatochip to ensure the correct backend is used. Tests were added to verify the fallback behavior and that keycard is preserved for satochip filters.

+# BIP85 GPG Version History
+
+SeedSigner implements [BIP85](https://github.com/bitcoin/bips/blob/master/bip-0085.mediawiki)
+for deterministic GPG key derivation. The derivation scheme has evolved through
+several versions as the spec and available hardware matured.
+
+## Overview
+
+| Version | Period | Tags | Key change |
+|---------|--------|------|------------|
+| v0 | Aug 31 – Sep 14, 2025 | *(development only, no release)* | Initial implementation; all keys use app 828365 |
+| v1 | Sep 15, 2025 – Mar 8, 2026 | `SS0.8.6+Satochip+Earthdiver-B4` … `SeSi-0.8.6+ShSi-B8` | Separate BIP85 app per curve |
+| v2 | Mar 9, 2026 – Jun 2026 | `SeSi-0.8.6+ShSi-B9`, `SeSi-0.8.6+ShSi-B10` | Unified app 828365 with `key_type` codes |
+| v3 | Jun 2026+ (planned) | *(B11-TestingFixes branch, unreleased)* | Split RSA (828365) and ECC (828366) apps |
+
+## Detailed per-version description
+
+### v0 (development — unreleased)
+
+First working implementation. Every curve used the same BIP85 app number and
+a simple `[param, index]` path.
+
+- **App**: `828365'` for all key types
+- **Path format**: `m/83696968'/828365'/{param}'/{index}'`
+- **Param**: `{key_bits}` for RSA (e.g. 2048), `259` for Curve25519, `256` for ECDSA curves
+- **Curves**: RSA 2048/3072/4096, Curve25519, secp256k1, NIST P-256
+- **Tags**: None — development-only. The compatible upstream
+  [bipsea](https://github.com/3rdIteration/bipsea) test vectors were never
+  generated for this version.
+
+### v1 (tagged releases B4 through B8)
+
+Each curve got its own BIP85 app number. ECC was restricted to 256-bit.
+
+- **Apps**:
+
+  | Curve | App |
+  |-------|-----|
+  | RSA | `828365'` |
+  | Curve25519 | `828366'` |
+  | secp256k1 | `828367'` |
+  | NIST P-256 | `828368'` |
+  | Brainpool P-256 | `828369'` |
+
+- **Path format**: `m/83696968'/{app}'/256'/{index}'` (ECC); `m/83696968'/828365'/{bits}'/{index}'` (RSA)
+- **Key type codes**: Not used — the curve was encoded in the app number
+- **Curves**: RSA, Curve25519, secp256k1, NIST P-256, Brainpool P-256
+- **Tags**: `SS0.8.6+Satochip+Earthdiver-B4` through `SeSi-0.8.6+ShSi-B8`
+
+### v2 (tagged releases B9, B10)
+
+Unified all curves under a single app number with a `key_type` discriminator.
+Added P-384, P-521, Brainpool P-384, Brainpool P-512.
+
+- **App**: `828365'` for all key types
+- **Path format**: `m/83696968'/828365'/{key_type}'/{key_bits}'/{index}'[/{sub_index}']`
+- **Key type codes**:
+
+  | Code | Curve |
+  |------|-------|
+  | 0 | RSA |
+  | 1 | Curve25519 |
+  | 2 | secp256k1 |
+  | 3 | NIST P-256 / P-384 / P-521 |
+  | 4 | Brainpool P-256 / P-384 / P-512 |
+
+- **Curves**: RSA, Curve25519, secp256k1, NIST (P-256/P-384/P-521), Brainpool (P-256/P-384/P-512)
+- **Tags**: `SeSi-0.8.6+ShSi-B9`, `SeSi-0.8.6+ShSi-B10`
+
+### v3 (B11-TestingFixes branch — unreleased)
+
+**Breaking change for ECC keys only.** RSA key derivation is identical to v2.
+
+Splits RSA and ECC into separate apps and remaps ECC `key_type` codes so the
+least-used curve (Brainpool) occupies code 0, reducing migration friction.
+
+- **Apps**:
+
+  | Family | App |
+  |--------|-----|
+  | RSA | `828365'` (unchanged from v2) |
+  | ECC | `828366'` (new) |
+
+- **Path format**:
+  - RSA: `m/83696968'/828365'/0'/{bits}'/{index}'[/{sub_index}']`
+  - ECC: `m/83696968'/828366'/{key_type}'/{key_bits}'/{index}'[/{sub_index}']`
+- **ECC key type codes** (remapped):
+
+  | Code | Curve |
+  |------|-------|
+  | 0 | Brainpool P-256 / P-384 / P-512 |
+  | 1 | Curve25519 |
+  | 2 | secp256k1 |
+  | 3 | NIST P-256 / P-384 / P-521 |
+
+- **RSA key type code**: 0 (unchanged from v2)
+- **Curves**: Same as v2

+
+## Notes
+
+- **v0 was never released** — no tagged release or public build contains it.
+  The compatible bipsea test vectors were generated starting from v1.
+- **v2 → v3 is a breaking change for ECC keys** — the app number changed
+  from `828365'` to `828366'` and key_type codes were remapped. RSA keys
+  are unaffected.
+- **Upstream SeedSigner (v0.8.7)** does **not** contain any GPG support.
+  All versions described above are on the
+  [3rdIteration](https://github.com/3rdIteration/SeedSigner) fork.
