Summary

Registration hid the license replacement action when the current boot USB was blacklisted, even though the installed license remained registered to an old TPM after a hardware swap. This restores the existing Replace Key action for that supported state and explains the TPM mismatch without changing the flash blacklist.

Why This Exists

CLD-1117: Registration suppresses TPM “Replace Key” flow when boot USB is blacklisted

In the normal EBLACKLISTED state, the server-state data is an error, so the existing keyInstalled predicate is false. The existing TPM action therefore disappeared even when the boot USB was blacklisted, the installed key was registered to a different old TPM GUID, and a new usable TPM GUID was present.

Resolution

  • Extend the existing Registration eligibility predicate for normal EBLACKLISTED state, requiring a key file, a flash boot device, a usable detected TPM GUID, and a different registered TPM GUID.
  • Expose tpmGuid in the PHP server-state fallback with a null-safe default.
  • Keep the detected and registered TPM GUIDs visible for diagnosis.
  • Add the existing Replace Key action for this exact mismatch case.
  • For this mismatch, send the detected new TPM as guid (replacement target), retaining the old TPM as regGuid (installed license source). Reuse the existing TPM replacement payload.
  • Set state: EGUID on this replacement callback so Account describes the TPM license mismatch. The local boot flash state remains EBLACKLISTED; it must not be attributed to the TPM target.
  • Do not show Move License to TPM for this case because the installed license is already TPM-bound.
  • Keep the new mismatch keys present in every locale bundle using the documented English fallback until translations are supplied.
  • Use hardware-swap-specific mismatch copy instead of generic guidance to copy a key file.
  • Keep EBLACKLISTED1 and EBLACKLISTED2 excluded.

Behavior Changes

A licensed server sees the TPM mismatch state and the existing Replace Key action only when all of these conditions hold:

  • the current boot device is a blacklisted flash drive in normal EBLACKLISTED state;
  • a local key file is present;
  • a usable TPM is detected; and
  • the installed key is registered to a different TPM GUID.

The screen shows both the registered (old) TPM GUID and detected (new) TPM GUID. It explains that a hardware swap can cause the mismatch and that the blacklisted boot flash is not changed. Invalid blacklisted states, missing-key cases, flash-registered keys, and keys already registered to the detected TPM keep their existing behavior.

The Move License to TPM action remains available in the normal installed/trial TPM-transfer flows, but is intentionally omitted from this blacklisted-flash mismatch state.

Verification

  • pnpm --filter @unraid/web exec vitest run — 67 files passed; 1 unrelated existing failure in OnboardingCoreSettingsStep.test.ts (timeZone trusted-default assertion), with 693 passed and 6 skipped.
  • Focused Registration test — 21 passed after confirming Move License to TPM is absent and Replace Key remains functional.
  • Locale key parity — all three mismatch keys are present in all 25 locale bundles.
  • Focused account/server store tests — 48 passed (16 account-store, 32 server-store); together with Registration, 69 focused tests passed.
  • Targeted ESLint and Prettier checks for the changed files — passed.
  • pnpm --filter @unraid/web type-check — passed.
  • Replace payload regression — the mismatch action forwards the detected new TPM as guid and the old TPM as regGuid; 53 Registration/server tests passed after this correction. Targeted lint and type-check passed. Two independent focused reviewers found no blockers.
  • git diff --check — passed.
  • Latest callback-state correction: 21 Registration tests, ESLint, Prettier and type-check passed; both focused reviewers found no blockers. All CI checks passed at aad603d. Published preview build 24 (2026.09.15.1613) includes the correction.
  • Preview plugin — https://preview.dl.unraid.net/unraid-api/tag/PR2083/dynamix.unraid.net.plg

Review Notes

The change is bounded to the existing server-state contract, Registration UI, locale fallback copy, and Registration tests. The branch includes the required forecast and final review receipts. CodeRabbit's current check is green. Its latest historical review still requests replacing the documented English fallback values with translations; that request conflicts with the repository's documented locale workflow, so no review comment was dismissed or resolved.

The callback-state correction is ready for review with passing CI and preview build 24 available. The actual license replacement has not been performed during this verification. No merge, auto-merge, review comment, or thread resolution was performed.

Walkthrough

The server state now includes tpmGuid. The server store detects TPM license mismatches during EBLACKLISTED. Registration displays mismatch details and uses Replace Key with the registered TPM GUID. Tests cover valid and invalid states.

Changes

Merge Risk: 🔵 Low · up to 1f85d

The TPM-mismatch registration flow works, but some supported non-English locales display English guidance instead of localized text. This is a bounded localization issue with low merge risk.

Add all TPM-mismatch keys to every supported locale. web/src/locales/en.json defines server.state.eblacklisted.tpmMismatch.heading, server.state.eblacklisted.tpmMismatch.humanReadable, and server.state.eblacklisted.tpmMismatch.message, but the 24 non-English supported locale files define none of them. The i18n fallback uses English, so these locales show English TPM-mismatch text instead of localized text. Add all three keys to each supported locale.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Translate the TPM mismatch strings in every non-English locale bundle.

When EBLACKLISTED has a TPM mismatch, web/src/store/server.ts:731-739 resolves all three keys with t(...). Every non-English bundle defines those keys with English values, so vue-i18n serves those values instead of using its English fallback for missing keys. Translate heading, humanReadable, and message in all 24 non-English files under web/src/locales, including ar, bn, ca, cs, no, pl, pt, ro, ru, sv, uk, and zh.
