Add validation for sourceCode maximum length of 50 characters

[Copilot]

OMOP CDM's concept_code field is VARCHAR(50). The Usagi file validator was missing a check to ensure sourceCode doesn't exceed this limit.

Changes

• Validation rule (R/validateUsagiFile.R:100): Added SourceCode.is.more.than.50.characters = field_length(sourceCode, min = 0, max = 50) following the same pattern as the existing SourceName.is.more.than.255.characters validation

• Test data (inst/testdata/VOCABULARIES/ICD10fi/ICD10fi_with_errors.usagi.csv): Added test case with 52-character sourceCode

• Test assertions (tests/testthat/test-validateUsagiFile.R:91-97): Verifies validation detects oversized sourceCodes, sets error message, and flags entries appropriately

Entries with sourceCode > 50 characters will now be flagged with ERROR: SourceCode is more than 50 characters and mappingStatus set to FLAGGED.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• cloud.r-project.org
  • Triggering command: /usr/lib/R/bin/exec/R /usr/lib/R/bin/exec/R --vanilla -e options(repos~+~=~+~c(CRAN~+~=~+~'REDACTED'));~+~install.packages('validate',~+~dependencies=TRUE) (dns block)
• esm.ubuntu.com
  • Triggering command: /usr/lib/apt/methods/https /usr/lib/apt/methods/https (dns block)
• packagemanager.posit.co
  • Triggering command: /usr/lib/R/bin/exec/R /usr/lib/R/bin/exec/R -e options(repos~+~=~+~c(CRAN~+~=~+~'REDACTED'));~+~install.packages(c('validate',~+~'checkmate',~+~'dplyr'),~+~dependencies=TRUE) (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

Comments on the Issue (you are @copilot in this section)

@javier-gracia-tabuenca-tuni In validateUsagiFile.R line 99 should include a validation where SourceName is more that 50 characters

also add a test in test-vlaidateUsagiFile.R
line 90

code and test should be similar to SourceName.is.more.than.255.characters

• Fixes Missing check for large conceptCode #64
