What does this PR do?

Fixes #329 (error -80045 on gsa login).

We were sending client info generated from Android Anisette, but claiming to be a Mac. Seems like GrandSlam no longer likes this mismatch.

How was it tested?

  • Run xtool ds certificates after updating -> logged out, provisioning reset
  • Re-auth works

Summary by CodeRabbit

  • Updates
    • Authentication now identifies the client as a Pixel 7 running Android 14 rather than using a macOS-style client description.
    • The provider ID is now consistent across platforms. Existing provisioning may be reset if its saved provider ID differs.
    • Before password login, a notice explains the emulated device and environment, recommends considering a secondary Apple ID, and says credentials are sent only to Apple.

📝 Walkthrough

Password login now uses a fixed Anisette provider ID and Pixel 7 / Android 14 client string. Before prompting for credentials, it prints a notice about device emulation, secondary Apple IDs, and credential handling.

Changes: Password Login

Layer / File(s) Summary
Anisette client identity
Sources/XKit/GrandSlam/Anisette/ADIDataProvider.swift, Sources/XKit/GrandSlam/Anisette/DeviceInfo.swift
The provider ID now returns "2" on all platforms. The client string now identifies a Pixel 7 running Android 14.
Password login notice
Sources/XToolSupport/AuthCommand.swift
Password login prints a notice before the credential prompt. The notice describes device emulation, suggests considering a secondary Apple ID, and states that credentials are only sent to Apple.

Priority: ➖ Normal

Estimated code review effort: 2 (Simple) | ~10 minutes

Change: Bug fix · Severity of issue fixed: Medium

Merge Risk: 🔵 Low · up to 146f6

The login notice makes an absolute claim about where credentials are sent that the code does not enforce. Soften or remove it before merging; otherwise the login identity change is a small, contained edit.

…here

- --real-init builds the structurally real SRP init body that
  AsyncAppleAccount._gsa_authenticate sends (srp.User A2k over a synthetic,
  nonexistent Apple ID - init precedes any credential check, so this is still
  not a sign-in attempt) and reports the response plist's Status.ec/em
- --anisette-json loads a provisioned cpd dump, --anisette-junk fills
  deterministic placeholders, --cpd-set/--cpd-unset vary single body fields
- The edge probes remain untouched; the doc comment that described this mode
  as future work now describes what it found
- With it, the 2026-10-12 refusal localises to one check: an Android-minted
  X-Apple-I-MD-M under a macOS client-info is refused ec=-80045 before OTP,
  serial or device-id are looked at; missing MD-M is -80009, malformed is
  -29004, missing OTP is -80010 - and an Android client-info over a freshly
  Android-provisioned machine id is answered ec=0 (issue parawanderer#248,
  xtool-org/xtool#337)

rubo77 added a commit to rubo77/OpenTagViewer that referenced this pull request Oct 14, 2026
Since 2026-10-12 Grand Slam refuses SRP init (ec=-80045) when a machine id
minted by Apple's Android ADI libraries is presented under a macOS or iPhone
client-info - issue parawanderer#248, and every install of this app.

- Hardware.ANDROID (Pixel 7 / Android 14 / UQ1A.240205.002, the string xtool
  verified in xtool-org/xtool#337) is the new DEFAULT; canSignIn() marks
  LEGACY_MAC and IPHONE as refused at the handler
- LocalAnisette replaces a stored identity whose profile can no longer sign
  in and wipes files/anisette/provisioning before the library is opened, so
  ADI re-provisions under the Android claim - a Mac-provisioned machine id
  presented as Android is answered hsc=434. Costs affected installs one
  re-login; the alternative is an install that can never sign in again
- profileToShow describes the profile the next load will actually use
- Tests: AdiDeviceIdentityTest pins the Android client-info string and
  canSignIn(); LocalAnisetteIdentityTest covers keep-vs-replace and the
  provisioning wipe; test_identity.py pins that the six bridged values
  render as the verified client-info through FindMy.py's own composer

Verified end to end: a freshly Android-provisioned machine id answers ec=0
via scripts/probe_gsa_signin.py --real-init, and on a Pixel 8 Pro this build
downloads the libraries, provisions under the Android identity
(ADIProvisioningEnd = 0) and signs in - password and 2FA accepted - through
to the account step. 469 JVM tests, 46 pytest, 35 instrumented tests green.

Since xtool-org#337, the GSA URL bag lookup sends the Android client info, so
Apple returns the reduced Android bag pointing at gsd.apple.com instead
of gsa.apple.com (see xtool-org#339). Matches isideload 0.4.5:

- Use the Mac client info only for the URL bag lookup
- Use the Android client info and akd user agent for all other GSA
  requests, including ADI provisioning
- Stop sending Mac hardware identifiers in cpd
