1-1:⚠️ Potential issue | 🔴 CriticalCI pipeline failure: branch coverage 83.78% < 84% threshold.
The pipeline reports that Jest branch coverage is below the 84% threshold. This needs to be addressed before merge — likely by adding tests for the new
linkWalletMethod/linkJwtMethodbranches (e.g., missing SIWE fields, cross-account collision, already-linked scenarios).apps/web/src/components/file-browser/ImagePreviewDialog.tsx (1)
87-87:⚠️ Potential issue | 🟠 MajorDo not use
.bufferonUint8Arrayfor Blob construction.
plaintext.buffercan reference a larger underlyingArrayBufferthan the typed array's view, causing silent data corruption. Pass the typed array directly.🐛 Proposed fix
- const blob = new Blob([plaintext.buffer as ArrayBuffer], { type: mime }); + const blob = new Blob([plaintext], { type: mime });As per coding guidelines: "Never use
.bufferon Uint8Array for Blob construction; pass the typed array directly to avoid silent data corruption from including extra bytes."apps/web/src/api/models/vaultExportDto.ts (1)
8-27:⚠️ Potential issue | 🟡 MinorFix OpenAPI schema for
derivationMethodto correctly generatestring | nullinstead of{ [key: string]: unknown } | null.The generated frontend type
VaultExportDtoDerivationMethodis overly broad ({ [key: string]: unknown } | null), while the backend DTO correctly specifiesstring | nulland all tests expect either the literal string'web3auth'ornull. This mismatch causes the frontend to lose type safety when working with the derivation method value.The issue is in the OpenAPI schema generation (orval) interpreting the backend DTO spec incorrectly. The backend annotations should be reviewed to ensure they properly constrain the type to
string | null(or an enum of'web3auth'for stricter typing).apps/web/src/api/models/index.ts (1)
11-13:⚠️ Potential issue | 🟡 MinorOld
derivationInfo-related exports are unused and should be removed from the OpenAPI spec.Lines 11–13 export
derivationInfoDto,derivationInfoDtoDerivationVersion, andderivationInfoDtoMethod, and line 51 exportsvaultExportDtoDerivationInfo. These types appear nowhere outside the models folder and are not referenced byVaultExportDto, which instead usesderivationMethod(line 52). Since this is a generated file, the root cause is in the backend OpenAPI spec still defining these unused schemas. Update the spec to removeDerivationInfoDtoschema references so they stop being generated.
🤖 Fix all issues with AI agents
In `@apps/api/src/auth/auth.service.ts`:
- Around line 299-303: The error message thrown when crossAccountMethod is
detected uses a faulty ternary in auth.service.ts (the throw in the block
referencing crossAccountMethod) that always returns "email"; change the ternary
to emit distinct strings based on authMethodType (e.g., use "Google account" or
"Google" when authMethodType === 'google' and "email" or "email address"
otherwise) so the BadRequestException accurately states which auth method is
already linked to another account.
- Around line 93-100: The safety-net in auth.service.ts that saves a missing
auth method always hardcodes type: 'email' (saving via authMethodRepository.save
when authMethod is falsy); change it to derive the correct type from the
authentication context/JWT payload (e.g., inspect the incoming token or request
for provider indicators such as a provider claim, presence of email vs wallet
address, or a custom claim like auth_provider) and use that derived value
instead of the literal 'email' when calling authMethodRepository.save for the
user/identifier; ensure the logic lives near the existing auth resolution code
so functions/variables like authMethod, identifier, user, and
authMethodRepository are used consistently and fallback only with a correctly
computed type.
In `@apps/api/src/auth/controllers/identity.controller.ts`:
- Line 213: The code reads SIWE_DOMAIN with
this.configService.get<string>('SIWE_DOMAIN', 'localhost') in
identity.controller.ts which falls back to 'localhost' — add SIWE_DOMAIN to
apps/api/.env.example and change startup behavior to fail safe in production:
remove or avoid a permissive 'localhost' default for SIWE_DOMAIN, validate the
env var on app start (e.g. in bootstrap or ConfigService initialization) and
throw a clear error if SIWE_DOMAIN is missing or set to 'localhost' when
NODE_ENV !== 'development'; reference the existing config lookup
(this.configService.get('SIWE_DOMAIN', ...)) and identity controller to
implement the validation and enforcement.
In `@apps/api/src/auth/dto/identity.dto.ts`:
- Around line 70-89: The WalletVerifyDto allows unbounded inputs: add length
constraints to the message and signature fields — for message (property name
message on class WalletVerifyDto) add a MaxLength of ~1024 to prevent oversized
payloads; for signature (property name signature on class WalletVerifyDto)
enforce exact Ethereum signature length by replacing the loose hex pattern with
either a stricter regex ^0x[0-9a-fA-F]{130}$ or add a `@Length`(132,132) plus the
existing hex match; ensure you update/keep the class-validator decorators (e.g.,
`@MaxLength`, `@Length`) and adjust the `@Matches` pattern accordingly so validation
rejects oversized or malformed values.
In `@apps/api/src/auth/services/siwe.service.ts`:
- Around line 1-5: Update the import for verifyMessage so it comes from the viem
root export instead of viem/utils; locate the import block at the top of
apps/api/src/auth/services/siwe.service.ts and change the import source so that
verifyMessage is imported from 'viem' (match the other viem imports like
getAddress, parseSiweMessage, validateSiweMessage) to avoid runtime module
resolution errors.
In `@apps/api/src/vault/dto/vault-export.dto.ts`:
- Around line 45-51: The OpenAPI schema for the derivationMethod property is
being inferred incorrectly; update the ApiPropertyOptional decorator on
derivationMethod in vault-export.dto.ts to include an explicit type: String
option so Swagger generates a string | null schema (keep the TypeScript property
signature derivationMethod!: string | null intact); i.e., add type: String to
the ApiPropertyOptional metadata for the derivationMethod property to fix the
generated client type.
In `@apps/web/src/api/models/vaultExportDtoDerivationMethod.ts`:
- Line 13: The OpenAPI schema for VaultExportDto's derivationMethod is generated
as an object because the VaultExportDto property lacks an explicit type in its
decorator — open the VaultExportDto (vault-export.dto.ts) and on the
derivationMethod property’s `@ApiPropertyOptional` decorator add the explicit type
(e.g. type: String or () => String) so the schema emits "type":"string" (keeping
the nullable behavior), then regenerate the client (orval) to produce
VaultExportDtoDerivationMethod as string | null; reference the VaultExportDto
class and the derivationMethod property when making the change.
In `@apps/web/src/api/models/walletVerifyDto.ts`:
- Around line 1-14: The header in apps/web/src/api/models/walletVerifyDto.ts
declares "Generated by orval v7.18.0" but package.json pins orval to ^7.3.0;
either update the dependency in apps/web/package.json to ^7.18.0 to match the
generated file header or regenerate the API typings with the installed orval
version so the header reflects the real generator; locate the WalletVerifyDto
file to confirm header change and update the package.json or run the orval
regeneration command used in the repo (referencing the orval dependency entry in
package.json and the WalletVerifyDto output) to keep versions consistent.
In `@apps/web/src/components/auth/LinkedMethods.tsx`:
- Around line 190-212: The dismiss button only calls setActionError(null) so
errors coming from mutationLinkError will persist; update the dismiss handler in
the linked-methods error block to also clear the mutation error exposed by your
hook (e.g., call resetLinkError or mutationLink.reset()) when mutationLinkError
is the active source, or only render the dismiss button when actionError is
non-null — reference displayError, actionError, mutationLinkError,
setActionError and whatever reset function your useLinkedMethods hook provides
(e.g., resetLinkError or mutationLink.reset) and ensure the handler clears both
sources appropriately.
- Around line 136-142: The DTO validation currently rejects an empty idToken
which breaks wallet linking; update the LinkMethodDto by adding `@IsOptional`() to
the idToken property (removing or replacing `@IsNotEmpty`()) and update the
idToken comment to state it is only required for non-wallet loginType, so wallet
flows (loginType === 'wallet') can omit idToken; ensure LinkMethodDto (idToken)
still validates other fields (siweMessage/siweSignature) for wallet linking.
🧹 Nitpick comments (19)
apps/api/jest.config.js (1)
43-43: Comment-only change, no functional impact.The branch threshold remains at 84. Consider adding per-file coverage thresholds for the new
siwe.service.tsandidentity.controller.tsfiles if you want to enforce the same rigor as other auth services, but this is optional given the global thresholds cover them.apps/api/src/auth/dto/link-method.dto.ts (1)
18-31: Missing conditional validation: wallet fields should be required whenloginTypeis'wallet'.All three wallet fields (
walletAddress,siweMessage,siweSignature) are@IsOptional()unconditionally. A request withloginType: 'wallet'but missing SIWE data will pass DTO validation and only fail deeper in the service layer (or worse, produce confusing errors). Use@ValidateIfto enforce them conditionally.♻️ Proposed conditional validation
- `@ApiPropertyOptional`({ description: 'Wallet address (required when loginType is wallet)' }) - `@IsOptional`() + `@ApiPropertyOptional`({ description: 'Wallet address (required when loginType is wallet)' }) + `@ValidateIf`((o) => o.loginType === 'wallet') + `@IsNotEmpty`() `@IsString`() walletAddress?: string; - `@ApiPropertyOptional`({ description: 'SIWE message (required when loginType is wallet)' }) - `@IsOptional`() + `@ApiPropertyOptional`({ description: 'SIWE message (required when loginType is wallet)' }) + `@ValidateIf`((o) => o.loginType === 'wallet') + `@IsNotEmpty`() `@IsString`() siweMessage?: string; - `@ApiPropertyOptional`({ description: 'SIWE signature (required when loginType is wallet)' }) - `@IsOptional`() + `@ApiPropertyOptional`({ description: 'SIWE signature (required when loginType is wallet)' }) + `@ValidateIf`((o) => o.loginType === 'wallet') + `@IsNotEmpty`() `@IsString`() siweSignature?: string;You'll need to add
ValidateIfto the import:-import { IsString, IsNotEmpty, IsIn, IsOptional } from 'class-validator'; +import { IsString, IsNotEmpty, IsIn, IsOptional, ValidateIf } from 'class-validator';apps/api/src/migrations/1700000000000-FullSchema.ts (1)
82-85: Consider a unique index onidentifier_hashinstead of a non-unique one.The cross-account collision check ("wallet already linked to another account") is enforced at the service layer, but a unique index on
identifier_hashwould provide a database-level safety net against race conditions where two concurrent requests link the same wallet to different accounts. Sinceidentifier_hashis nullable, most databases (PostgreSQL included) allow multiple NULLs in a unique index, so non-wallet methods won't conflict.♻️ Proposed change
- await queryRunner.query( - `CREATE INDEX "IDX_auth_methods_identifier_hash" ON "auth_methods" ("identifier_hash")` - ); + await queryRunner.query( + `CREATE UNIQUE INDEX "IDX_auth_methods_identifier_hash" ON "auth_methods" ("identifier_hash")` + );apps/api/src/auth/services/siwe.service.ts (1)
67-80:getAddresswill throw on invalid input — consider wrapping in hash/truncate methods.Both
hashWalletAddressandtruncateWalletAddresscallgetAddress()which throws if the input is not a valid Ethereum address. If these methods are only ever called with addresses already validated byverifySiweMessage, this is safe. However, if they're used independently (e.g., during wallet linking from controller input), an unhandled viem error would surface as a 500 rather than a meaningful 400.♻️ Optional: Wrap getAddress in a try/catch
hashWalletAddress(address: string): string { + try { const checksummed = getAddress(address); return createHash('sha256').update(checksummed).digest('hex'); + } catch { + throw new UnauthorizedException('Invalid wallet address'); + } }.planning/phases/12.3-siwe-unified-identity/12.3-CONTEXT.md (1)
44-48: Implementation deviates from plan: truncated display instead of AES-encrypted plaintext.The plan specifies "AES-encrypted plaintext for display in settings" but the implementation uses a pre-truncated
identifierDisplaycolumn (e.g.,0xAbCd...1234). The implementation is arguably simpler and avoids managing an encryption key for display purposes. Consider updating this planning doc to reflect the actual approach for future reference.apps/web/src/lib/web3auth/hooks.ts (1)
28-37: Consider anelsebranch for unexpected Core Kit status afterloginWithJWT.If
coreKit.statusis neitherLOGGED_INnorREQUIRED_SHAREafterloginWithJWT, the function silently resolves. This could mask an unexpected state. Anelsethrow (or at least a warning log) would make failures more visible.Suggested improvement
if (coreKit.status === COREKIT_STATUS.LOGGED_IN) { await coreKit.commitChanges(); - } - // REQUIRED_SHARE means MFA is enabled but device factor missing - // Phase 12.4 will handle this -- for now, throw so calling code can surface it - if (coreKit.status === COREKIT_STATUS.REQUIRED_SHARE) { + } else if (coreKit.status === COREKIT_STATUS.REQUIRED_SHARE) { + // REQUIRED_SHARE means MFA is enabled but device factor missing + // Phase 12.4 will handle this -- for now, throw so calling code can surface it throw new Error( 'Additional verification required. Multi-factor recovery is not yet supported.' ); + } else { + console.warn('[CoreKit] Unexpected status after loginWithJWT:', coreKit.status); }apps/api/src/auth/services/web3auth-verifier.service.ts (1)
110-117: Unconditional fallback to'email'silently swallows unknown verifier types.Line 116 returns
'email'even when no email is present and the verifier is unrecognized. If a wallet or future auth method accidentally routes through this extractor, it would be silently classified as email. Consider returning'wallet'when wallet data is present, or throwing for truly unrecognized verifiers to fail fast.Suggested improvement
// Default to email if email is present if (payload.email) { return 'email'; } - // Fallback - return 'email'; + // Check for wallet-like payload + const wallet = payload.wallets?.[0]; + if (wallet?.address || wallet?.public_key) { + return 'wallet'; + } + + // Fallback — email is safest default for social/passwordless verifiers + return 'email';apps/api/src/auth/auth.service.ts (2)
388-397:identifierandidentifierHashstore the same value — potential confusion.The wallet address hash is saved as both
identifierandidentifierHash. This meansidentifieris no longer a human-readable value for wallet methods (it's a hash), which breaks the implicit contract thatgetLinkedMethodsfalls back tomethod.identifierwhenidentifierDisplayis absent. IfidentifierDisplayis ever missing for a wallet method, users will see a raw SHA-256 hash. Consider storing a sentinel or the truncated address inidentifierinstead, or documenting this dual-storage explicitly.
344-357: Dynamicimport('viem/siwe')on every wallet-link call adds per-request latency.
parseSiweMessageis imported dynamically each timelinkWalletMethodis invoked. For a backend service, a top-level static import is simpler and avoids repeated module resolution overhead.Proposed fix
Add a top-level import and remove the dynamic one:
+import { parseSiweMessage } from 'viem/siwe'; ... - const { parseSiweMessage } = await import('viem/siwe');apps/web/src/components/file-browser/TextEditorDialog.tsx (1)
114-115: Pre-existing: prefer passing Uint8Array directly to Blob instead of.buffer.Line 114's
.slice()mitigates the offset-view problem, but the coding guideline explicitly states to pass the typed array directly toBlobrather than using.buffer. This isn't introduced by this PR, but worth a follow-up fix.♻️ Suggested fix
const ciphertextBytes = encrypted.ciphertext.slice(); - const blob = new Blob([ciphertextBytes.buffer as ArrayBuffer]); + const blob = new Blob([ciphertextBytes]);As per coding guidelines: "Never use
.bufferon Uint8Array for Blob construction; pass the typed array directly to avoid silent data corruption from including extra bytes."apps/api/src/auth/controllers/identity.controller.spec.ts (1)
108-109:clearAllMocksvsresetAllMocks— intentional change?
clearAllMocksclears call counts and results but preserves mock implementations, whileresetAllMocksalso removes implementations. Since mocks are configured per-test in this file, both work, butresetAllMocksprovides stronger isolation. This is fine as-is given the test structure.apps/web/src/App.css (1)
678-683: Hardcodedfont-size: 10pxbreaks the design token pattern.Lines 679 and 846 use
font-size: 10pxdirectly instead of a CSS custom property likevar(--font-size-xs)or similar, which is used consistently throughout the rest of the file. If10pxis intentionally smaller than--font-size-xs, consider adding a--font-size-2xstoken.Also applies to: 844-849
apps/web/src/components/auth/WalletLoginButton.tsx (2)
41-46: MissinghandleSiweFlowinuseEffectdependency array — stale closure risk.
handleSiweFlowis referenced inside this effect but is not listed in the dependency array and is not memoized withuseCallback. While thesiweInProgressref guard prevents double-invocation in practice, the effect captures a stale version ofhandleSiweFlowif the parent re-renders with newonLogin/signMessageAsyncreferences.Since
handleConnectorClickalready callshandleSiweFlowdirectly afterconnectAsyncresolves (line 124), consider whether thisuseEffectfallback path is still needed. If it is (for connectors that resolve asynchronously), wraphandleSiweFlowinuseCallbackand include it in the dependency array.♻️ Suggested approach
Either remove the
useEffectentirely (sincehandleConnectorClickdrives the flow), or stabilizehandleSiweFlow:+ const handleSiweFlow = useCallback(async (walletAddress: `0x${string}`) => { + // ... existing body ... + }, [signMessageAsync, disconnect, onLogin]); + useEffect(() => { if (isConnected && address && phase === 'connecting' && !siweInProgress.current) { siweInProgress.current = true; handleSiweFlow(address); } - }, [isConnected, address, phase]); + }, [isConnected, address, phase, handleSiweFlow]);
86-98: Variablemessageshadows the outer SIWE message.The
const messageon line 87 (error message string) shadows themessageon line 56 (SIWE message string). Not a runtime bug since the outermessageisn't needed in the catch block, but it reduces readability.✏️ Rename to avoid shadowing
} catch (err) { - const message = err instanceof Error ? err.message : 'Wallet login failed'; + const errMessage = err instanceof Error ? err.message : 'Wallet login failed'; // Handle user rejection specifically if ( - message.includes('User rejected') || - message.includes('user rejected') || - message.includes('ACTION_REJECTED') + errMessage.includes('User rejected') || + errMessage.includes('user rejected') || + errMessage.includes('ACTION_REJECTED') ) { setError('Signature request was rejected'); } else { - setError(message); + setError(errMessage); }apps/web/src/lib/api/auth.ts (1)
35-41: Consider a discriminated union forLinkMethodRequesttype safety.The current flat type allows invalid combinations (e.g.,
loginType: 'google'withsiweMessageset, orloginType: 'wallet'without SIWE fields). A discriminated union would enforce correct field combinations at compile time.✏️ Discriminated union approach

262-283:isLoggingInas a closure-captured guard + dependency creates a subtle race.
isLoggingInis a React state value captured in the closure and also listed in the dependency array. If two rapid calls arrive before the state update flushes, both closures seeisLoggingIn === falseand proceed. This is the same pattern used byloginWithGoogle/loginWithEmail, so it's a pre-existing issue rather than a new regression—flagging for awareness.A
useRefguard (similar torestoringRef) would be race-free. Low priority since the UI button is likely disabled while loading.apps/api/src/auth/controllers/identity.controller.ts (1)
52-59: Redis instantiated directly instead of via NestJS DI — creates an unmanaged connection.Creating a
new Redis()inside the constructor bypasses NestJS's dependency injection. This means:
- An extra connection pool outside the shared Redis provider that other services (e.g.,
EmailOtpService) likely use.- Harder to mock in tests (you need to intercept the constructor).
- If multiple instances are created (e.g., request-scoped), each gets its own connection.
Consider injecting a shared Redis instance via a NestJS provider or module (e.g.,

390-399:identifierandidentifierHashstore the same value for wallet methods.Both fields are set to
addressHash. This means wallet methods use the hash as the primaryidentifier, which is consistent for cross-account collision queries but creates an asymmetry: for email/Google methodsidentifieris the raw value, while for wallet methods it's a hash. This could confuse future maintainers or queries that assumeidentifieris human-readable.If
identifierHashis the canonical lookup column for wallets, consider settingidentifierto the truncated display address (or null) to keep the column's semantics consistent, or add a brief comment documenting this intentional dual-use.

75-75: Good fix removing.buffer; theas BlobPartcast is redundant.
Uint8Arrayalready satisfies theBlobParttype (ArrayBufferView | ArrayBuffer | Blob | string), so the cast adds no safety. Passing the typed array directly is the correct approach per project guidelines. Consider dropping the cast for clarity.As per coding guidelines: "Never use
.bufferon Uint8Array for Blob construction; pass the typed array directly to avoid silent data corruption from including extra bytes."Proposed simplification
- const blob = new Blob([plaintext as BlobPart], { type: mimeType }); + const blob = new Blob([plaintext], { type: mimeType });
94-94:mimeTypeis used inside the effect (Line 75) but missing from the dependency array.If
mimeTypechanges whileopenanditemremain the same, the blob will use a stale MIME type. This is pre-existing and likely benign (mimeType is typically derived from the item), but worth noting.Similarly,
objectUrlis read on Line 40 but not in the deps — the stale reference means the revocation in the "closing" branch may miss the current URL. The cleanup function (Lines 88–92) correctly uses the localurlvariable, so actual leaks are unlikely.apps/api/src/auth/auth.service.spec.ts (2)

authMethodRepository.findOne.mockResolvedValue(null), then lines 213–215 override with twomockResolvedValueOnce(null)calls. Since all returnnull, this is functionally correct but the line 212 call is dead code that makes the mock chain harder to follow.♻️ Suggested cleanup
const mockUser = { id: 'user-id', publicKey: 'abc123' }; userRepository.findOne.mockResolvedValue(mockUser); - authMethodRepository.findOne.mockResolvedValue(null); authMethodRepository.findOne .mockResolvedValueOnce(null) // identifier lookup with sub .mockResolvedValueOnce(null); // userId fallback
778-804: Consider consolidating duplicate invocations for exception assertions.Several tests (here and in similar blocks) invoke the method under test twice — once to assert the exception class, once to assert the message — re-mocking all dependencies in between. You can do both in a single call:

- await expect(service.linkMethod('user-id', linkDto)).rejects.toThrow(BadRequestException); - // Reset mocks for second assertion - userRepository.findOne.mockResolvedValue(mockUser); - (jose.jwtVerify as jest.Mock).mockResolvedValue({ payload: mockPayload }); - authMethodRepository.findOne - .mockResolvedValueOnce(null) - .mockResolvedValueOnce(existingMethod); - await expect(service.linkMethod('user-id', linkDto)).rejects.toThrow( - 'This auth method is already linked to your account' - ); + await expect(service.linkMethod('user-id', linkDto)).rejects.toThrow( + expect.objectContaining({ + constructor: BadRequestException, + message: expect.stringContaining('already linked to your account'), + }) + );Or simply rely on the message assertion alone, since a matching message from a non-

46-46: Migration strategy needs detailed specification."Add migration for existing auth_methods rows" is underspecified for a sensitive operation that will hash all existing identifiers.
Consider documenting:

- Edge case handling: Null identifiers, malformed data, duplicate emails.
- Rollback strategy: Can the migration be safely reversed if issues arise?
- Testing plan: How to verify no users lose access after migration?
- Phased rollout: Consider a feature flag to gradually enable hashed lookups.

Cross-method email linking mechanism is underspecified.
After the migration, Google auth methods will store identifier_hash = SHA-256(sub) and email auth methods will store identifier_hash = SHA-256(email). These hashes are cryptographically unrelated even when the email matches.
How will findOrCreateUserByEmail link Google and email methods by email if both rely on different hashed lookups?
Possible solutions to specify:
- Store a separate
normalized_email_hashcolumn for all methods (Google, email, wallet if email provided) to enable cross-method email matching. - Use
identifier_displayfor cross-method email matching (though this may expose plaintext emails in lookups). - Maintain a separate email-to-userId mapping table.
- Accept that Google and email methods can't auto-link by email and require explicit manual linking.
This is a critical implementation detail that must be resolved before coding begins.

Good catch on the cross-method linking problem. We've decided to solve this by removing auto-linking entirely in the upcoming Phase 12.3.1 (Pre-Wipe Identity Cleanup).
Each auth method will be a fully independent identity:
- Google:
identifier_hash = SHA-256(google_sub) - Email:
identifier_hash = SHA-256(normalized_email) - Wallet:
identifier_hash = SHA-256(checksummed_address)
No normalized_email_hash column needed — findOrCreateUserByEmail and all cross-method email linking logic will be removed. Users who want multiple auth methods on the same account link them explicitly via the Settings page (already built in 12.3-04).
This sidesteps the hash-mismatch problem, is more transparent to users (no surprise account merging), and since we're wiping the DB before production, there's no migration to worry about.
See commit 579c4ed (Phase 12.3.1 insertion).

@FSM1, excellent architectural decision! Removing auto-linking and treating each auth method as an independent identity with explicit linking is cleaner and more transparent:
✅ Eliminates the hash-mismatch complexity — no need for normalized_email_hash or lookup fallbacks
✅ User-transparent — no surprise account merging; users control which methods link to which account
✅ Zero migration debt — pre-production DB wipe means clean slate
✅ Already implemented — Settings page linking flow from 12.3-04 handles this
The explicit linking model aligns well with CipherBox's security-first philosophy — users explicitly authorize account associations rather than having the system infer them.

Learning: In Phase 12.3.1 (Pre-Wipe Identity Cleanup), CipherBox removes all auto-linking of auth methods by email. Each auth method (Google, Email, Wallet) is now a fully independent identity with its own identifier_hash based on the credential type (SHA-256(google_sub), SHA-256(normalized_email), SHA-256(checksummed_address)). Users link methods explicitly via the Settings page; there is no cross-method email matching or findOrCreateUserByEmail logic.
