Let me analyze the results and generate a final response.

Schema update for 'never' interval is safely integrated
The codebase shows consistent handling of the "never" interval across all relevant components:

• Database schema in keys.ts includes "never" in the enum
• API routes and validation schemas properly include "never" as a valid option
• Frontend components (dashboard) correctly handle the "never" option in forms and UI
• Migration-related code properly supports the new interval option

No conflicts or inconsistencies found with existing records or schema definitions. The change has been properly propagated throughout the codebase.

The following scripts were executed for the analysis:

Script:

#!/bin/bash
# Verifying references to old refill intervals ('daily','monthly') in codebase
rg -A 3 "refill(\s*)?\{.*interval:\s?\"daily\"|\"monthly\"" 

Length of output: 15048

Let me gather more information about this validation and its usage in the UI to verify the concerns.

Let me check the client component to understand how this validation is used in the UI.

Based on the analysis of both the validation schema and the client component, I can now provide the final response:

Making the refill amount optional with min(0) is appropriate for this use case.
The validation is correctly implemented as the refill amount is only required when the limit is enabled and the refill interval is not "never". The UI handles this by:

1. Disabling the refill amount input when interval is "never"
2. Setting a default value of 0 when the field is enabled
3. Properly cleaning up the form when limit features are disabled

The following scripts were executed for the analysis:

Let me gather information about the usage of refillInterval and any potential constraints in the database schema.

This will help us:

1. Find all files using refillInterval to check for constraints
2. Look for schema definitions and validations
3. Find any SQL migrations that might have NOT NULL constraints

Let's check the actual schema definition and any validation logic around refillInterval to understand the constraints.

This will help us:

1. See the complete schema context around refillInterval
2. Check how "never" is handled in create/update operations
3. Look for any validation rules that might enforce non-null constraints

Let's check for any NOT NULL constraints in the database migrations and look at the actual usage of refillInterval in the codebase.

This will help us:

1. Find any NOT NULL constraints in migrations
2. Understand how refillInterval is handled during key creation/updates
3. Check for any default values that might have been set

Based on the gathered information, I can now provide a final response:

Verified: "never" enum value is safely implemented
The codebase shows that refillInterval is properly handled as a nullable field, with explicit null handling in both create and update operations. The schema allows for the new "never" value, and there are no NOT NULL constraints that would conflict with this change. The update logic specifically handles null cases by setting related fields (refillAmount, refillDay, lastRefillAt) to null as well.

Let me gather more information about how the interval, refillDay, and amount fields are used in the codebase.

Based on the search results, I can now provide a final response. The codebase already handles the logical consistency for "never" interval appropriately:

1. In the UI (apps/dashboard/app/(app)/apis/[apiId]/keys/[keyAuthId]/new/client.tsx), the amount and refillDay fields are automatically disabled when interval is set to "never".
2. The schema definitions consistently allow amount to be 0 (z.number().int().min(0)) and refillDay to be optional across all routes.
3. The OpenAPI descriptions clearly document the behavior of these fields.

No changes needed - the implementation already handles "never" interval consistently

The current implementation correctly handles the case when interval is "never":

• The UI automatically disables related fields
• The schema allows zero amount and optional refillDay
• The API documentation clearly describes the behavior

The following scripts were executed for the analysis:

Error: No shell scripts found

Script:

#!/bin/bash
# Search for the schema definition and usage of these fields
ast-grep --pattern 'z.object({
  $$$
  interval: $_,
  $$$
})'

# Also search for any direct references to these fields
rg -A 5 "interval.*never" 

Length of output: 28863

Let me search for related code to verify the handling of "never" interval and its interaction with refill logic.

Based on the search results, I can now provide a definitive response about the handling of the "never" interval:

Validation for "never" interval is properly implemented.

The codebase correctly handles the "never" interval case:

• When interval is "never", the UI disables the amount input field (apps/dashboard/app/(app)/apis/[apiId]/keys/[keyAuthId]/new/client.tsx)
• The database schema (internal/db/src/schema/keys.ts) properly supports the "never" value in the refill_interval enum
• When refill.interval is "never" or "none", the refill configuration is removed entirely (apps/dashboard/lib/trpc/routers/key/updateRemaining.ts)
• The refill functionality is only activated when interval is "daily" or "monthly", effectively making "never" act as a no-refill state

Let me gather more information about how the "never" interval is handled in the codebase.

Let me search for any validation or processing logic specifically related to refillDay.

Based on the search results, I can now provide a final response:

Handling of "never" interval is properly implemented

The codebase shows consistent handling of the "never" interval case:

• For "daily" interval: refillDay must be null (explicitly validated)
• For "monthly" interval: refillDay is used to specify the day of refill (1-31)
• For "never" interval: refillDay is effectively ignored as no refills occur, and the schema makes refillDay optional

The implementation in v1_keys_createKey.ts and v1_apis_listKeys.ts shows that refillDay is only considered when interval is "monthly", which is the correct behavior. The schema's description accurately documents that refillDay is only meaningful for monthly intervals.

Let me gather information about the form implementation and validation logic to verify this concern.

Let me check the validation schema to verify how the form handles the limit.refill.amount when interval is "never".

Based on the code analysis, I can now provide the final response:

Form validation and submission are properly handling the "never" interval case

The implementation is correct and safe because:

1. The form field is properly disabled when interval is "never" through the disabled prop
2. The validation schema makes the amount field optional with optional()
3. The form submission logic in onSubmit handles the refill data appropriately by:
   • Removing the entire limit object if limitEnabled is false
   • Only including refill data when it exists
   • Setting a default amount of 0 when needed

No unintended submissions of leftover values can occur as the validation and submission logic properly handle this case.
