launchBrowser() hangs indefinitely on Chrome 145 in the Android
emulator. Replaced with chrome-command-line proxy flag + force-stop/
restart + connectOverCDP. A polling retry loop (max 15 s) handles
CDP startup variance.
proxy_service.dart: added _ensureCardOpen() which calls isCardAttached()
and re-runs _tryOpenCard() if the emulator socket was closed (e.g. after
a bridge restart). Called before makeCredential and getAssertion in all
three handler paths so the app reconnects automatically without restart.
playwright.config.js: global timeout 180 s → 60 s.
All 4 tests in k_phone_android.spec.js now pass (16 s total).

Three new specs in tests/:
- k_phone_portal.spec.js: portal UI flow (enroll/login/status/logout/delete)
- k_phone_proxy.spec.js: 4 serial proxy-routing tests via Node http module;
requires adb forward for emulator use
- k_phone_android.spec.js: same 4 tests with Chrome running inside the
Android emulator via playwright.android; no port-forward needed,
auto-skips if no ADB device found
All tests use card_emulator_bridge.py for instant FIDO2 auto-approval —
no physical card or fingerprint interaction required in emulator mode.

tests/test_k_server.py:
- TestVerifyAssertionToken (12 tests): unit tests using raw P-256 keys —
valid accept, wrong path/method, tampered nonce/signature/key, cross-
resource replay, malformed/empty token, wrong cdj type, missing field.
- TestVerifyAssertionTokenRoundTrip (5 tests): end-to-end via CardEmulator
— register, getAssertion with bound challenge, build bundle as k_phone
does, verify on server. Tests include wrong path/method and cross-user
key swap. Skipped automatically if fido2 is not installed.
All 17 pass.
proxy_service.dart: add comment to _handleSessionLogin explaining why
random challenge is correct there (user-presence proof for portal session,
not per-request resource binding).

- _mockTokenServer now reads and captures the request body instead of
draining it — Completer type updated to ({HttpRequest, String rawBody})
- Two new tests: assert that url, method, nonce are present in the
/auth/get-token request body; verify POST requests carry method=POST
48/48 tests pass.

Each request to a gated endpoint now triggers a fresh FIDO2 assertion.
Challenge = SHA256(url|method|nonce) — bound to the specific resource.
The self-contained assertion bundle lets the server verify independently
without calling back to the phone.
- fido2_ops.dart: GetAssertionResult gains clientDataJson; getAssertion
accepts optional challenge override
- proxy_service.dart: _handleAuthGetToken accepts {url,method,nonce},
derives challenge, runs card assertion, returns b64url bundle
- filter_proxy.dart: _getAuthToken(uri, method) generates nonce and
passes binding fields to Component 2
- component3/phone.go: stateless GetTokenForRequest(url, method) —
no session caching, no expiry, one card touch per request
- component3/proxy.go: use GetTokenForRequest
- component3/main.go: remove --user flag (Component 2 picks enrolled user)
- k_server_app.py: _verify_assertion_token() — verifies path+method
match, challenge claim, and ECDSA-P256 signature; accepts both
legacy X-Proxy-Token and new Bearer assertion tokens

Local branch was started fresh on new Mac (2026-04-29) as a workspace
snapshot of the full project state, then extended with Phase 9 k_phone
work. Remote has the complete git history up to 2026-04-27.
This merge grafts the two histories together. Local content is preserved
in full (it is a strict superset of the remote state).
proxy_service.dart: _handleConnect gates on hasAnyActiveSession() (407 if
no active session), then connects directly to the upstream external target
(host:port from Host header), detaches the socket, and pipes bytes
bidirectionally. k_server is not involved in CONNECT tunnels.
filter_proxy_test.dart: replace _mockTcp() with _mockComp2Tcp() in the
CONNECT routing group so the mock speaks the full CONNECT handshake
(reads request headers, sends 200 Connection Established, pauses sub).
All 21 tests pass.

- k_phone/lib/filter_proxy.dart: Component 1 — raw-socket HTTP proxy with
gating filter; gated hosts relay to Component 2, others go direct
- k_phone/lib/session_manager.dart: add hasAnyActiveSession() for the
personal-device gated-proxy authorization model
- k_phone/test/filter_proxy_test.dart: full test suite for Component 1
- k_phone/test/enrollment_test.dart: full test suite for EnrollmentDb
- k_phone/integration_test/registration_login_test.dart: emulator integration test
- Misc k_phone lib fixes (ctaphid_channel, fido2_ops, proxy_service, main,
enrollment_db, k_server_client) and pubspec/Gradle updates
- CLAUDE.md + Workplan.md: document Component 1, k_phone module map,
gated terminology (replacing "allowlist"), pending CONNECT handler in
Component 2

Records CardEmulator addition, the two fido2-direct id=/raw_id= bug fixes,
and the expanded test count (100 → 122). Marks project status unchanged:
Phases 7 and 9 remain externally gated.

tests/card_emulator.py: software emulator of the ChromeCard FIDO2
authenticator. Implements make_credential and get_assertion with real P-256
cryptography and an in-memory credential store. Both methods accept
user_confirms=True/False to simulate the card's Yes/No confirmation dialog;
False raises CtapError(OPERATION_DENIED). refusing() returns a wrapper that
forces user_confirms=False for integration tests that route through
_with_direct_ctap2. forget_user() simulates card-side credential removal.
Module docstring serves as the usage guide.
tests/test_k_proxy.py: 22 new tests across TestCardEmulatorUnit (direct
emulator calls) and TestCardEmulatorIntegration (full ProxyState flows
covering register, authenticate, user-says-no, forget, two-user isolation,
and sign-count monotonicity).
k_proxy_app.py: fix two bugs where RegistrationResponse and
AuthenticationResponse were constructed with id= instead of raw_id=. Both
calls raised TypeError at runtime, silently caught by the surrounding except
block, making all fido2-direct register and authenticate calls fail.

- fido2-direct confirmed as deployed default after full browser flow with real card
- Document enroll-clears-session bug fix
- Document k_proxy unit test suite (100 tests)
- Record current deployed service state and port map

- Update module docstrings to concise service descriptions
- Add _require_json() helper to Handler in k_proxy and k_client_portal,
eliminating repetitive try/except JSON-parse blocks in handler methods
- Cache SSL context once in ClientState.__init__ instead of per-request
- Fix: ClientState.enroll() now calls /session/logout on k_proxy before
re-enrolling, so the old server-side session is invalidated rather than
left to expire (discovered via live test where re-register after login
caused subsequent logout to fail with missing bearer token)
- Add targeted comments explaining non-obvious invariants: _gc_locked lock
ownership, _with_direct_ctap2 retry-on-reopen, _require_session None
convention, will_close connection reuse, HTTP/1.1 body-drain requirement,
90 s interactive timeout margin, and enroll session-clearing rationale

100 tests covering session management, enrollment CRUD, probe and direct
FIDO2 auth routing, UpstreamPool connection handling, and all HTTP
endpoints via a live in-process server. Card (FIDO2/CTAP) and k_server
are fully mocked so the suite runs locally without hardware or VMs.
Also hardens the fido2.features.webauthn_json_mapping import guard to
tolerate older python-fido2 versions that lack the attribute.
