The latest commit extracted parseHl7DateToIso from DmpNhrAdapter.ts into a dedicated helper module: - New: packages/@doctolib/national-health-records/src/helpers/parseHl7DateToIso.ts — pure exported function, no dependencies - New: packages/@doctolib/national-health-records/src/helpers/parseHl7DateToIso.test.ts — 9 unit tests - Modified: packages/@doctolib/national-health-records/src/business/adapters/DmpNhrAdapter.ts — imports from '../../helpers/parseHl7DateToIso' Focus on: UpFront architecture compliance (is helpers/ a valid layer in this package structure?), naming conventions, import path style, separation of concerns.

Let me compile the review. --- Architecture Review: parseHl7DateToIso extraction (PR #240556) Critical Issues (must fix) None. The extraction does not violate separation of concerns: the function is a pure string transformer with no React imports and no data access. Placing it in src/helpers/ is correct. --- Warnings (should fix) 1. parseHl7DateToIso belongs in src/business/, not src/helpers/. src/helpers/ is the right layer for generic, domain-agnostic utilities (formatting, string manipulation, math). parseHl7DateToIso is not generic — it encodes knowledge specific to the HL7 DTM format as used by the DMP API and produces values consumed by domain objects (NhrDocument.creationDate, serviceInformation.startDate, etc.). That is a domain concern, which is the charter of src/business/. The UpFront rule is: src/business/ holds pure functions and domain types with no React imports. This function satisfies that contract exactly. It should live at: src/business/helpers/parseHl7DateToIso.ts src/business/helpers/parseHl7DateToIso.test.ts or, if the team prefers to keep it flat alongside the adapter: src/business/adapters/parseHl7DateToIso.ts src/business/adapters/parseHl7DateToIso.test.ts The adapter file already imports from ../../helpers/parseHl7DateToIso; moving the file to src/business/helpers/ would change that to ../helpers/parseHl7DateToIso — a one-level traversal that reads clearly without an alias. Note: src/helpers/ is not invalid here — it exists in dozens of packages in this monorepo. The concern is purely about semantic fit. If the team decision is that src/helpers/ holds all pure-function utilities regardless of domain specificity, this is acceptable practice across the codebase and the warning can be downgraded to a suggestion. 2. The parseHl7DateToIso function is not exported from src/index.ts. This is intentional if the function is package-internal only. But it should be a deliberate decision: if any other package may need to parse HL7 dates (e.g., a future NHR variant adapter), leaving it unexported forces duplication. The current placement in src/helpers/ gives it no path to export without also being added to src/index.ts. Document the intent or export it. --- Suggestions (consider improving) 1. The relative import depth from DmpNhrAdapter.ts is ../../helpers/ — two levels, not three. The #helpers/ alias threshold is 3+ ../ traversals, so the current relative import '../../helpers/parseHl7DateToIso' is below the alias threshold. No alias needed. This is correct as written. 2. Flat src/helpers/ is a single file today — no subdirectory risk. The UpFront rule prohibits subdirectories inside src/helpers/. With one file, there is nothing to flag now, but be aware: if the helpers/ layer grows, any grouping must not create subdirectories under it. If growth is anticipated, structuring inside src/business/ provides natural subdirectory support (src/business/helpers/, src/business/adapters/, etc.) without violating the flat-helpers rule. 3. Test file naming is correct. parseHl7DateToIso.test.ts is colocated with its source and follows the {mantissa}.test.ts derived-file naming pattern. The 9-case test suite covers the two valid formats, non-numeric inputs, undefined, empty string, and unrecognised lengths — no gaps. --- Summary The extraction itself is clean and the code quality is high. The single actionable item worth raising in the PR is whether src/helpers/ is the right layer for a domain-specific parser, with src/business/ being the architecturally preferred location under UpFront rules. Everything else — naming, test colocation, import depth, export style (named export, no default) — is correct.
