Automated fix via Hermes Agent. Closes #16

Fixes

Critical

C1: CreateBatch shadowed err with := in loop, causing partial commits on row-insert failure and silently dropping tx.Commit() errors. Fixed with named return and execErr loop variable.

High

H1: OrderBy was concatenated raw into SQL query (injection surface). Added whitelist validation at repo level (independent of HTTP allowlist).
H2: Organization().List dropped args in SelectContext call — IN placeholders were unbound, always erroring with IDs filter.
H3: CourseRepository.Get wrapped sql.ErrNoRows without translating to ErrNotFound, breaking the port contract.

Medium

Create now returns the created entity via Get instead of empty Course{}.
Fixed prepared statement leak in Organization.Create.
Unified time.Now() to time.Now().UTC() for consistency across repos.

Automated fix via Hermes Agent. Closes #16 ## Fixes ### Critical - **C1**: `CreateBatch` shadowed `err` with `:=` in loop, causing partial commits on row-insert failure and silently dropping `tx.Commit()` errors. Fixed with named return and `execErr` loop variable. ### High - **H1**: `OrderBy` was concatenated raw into SQL query (injection surface). Added whitelist validation at repo level (independent of HTTP allowlist). - **H2**: `Organization().List` dropped `args` in `SelectContext` call — IN placeholders were unbound, always erroring with IDs filter. - **H3**: `CourseRepository.Get` wrapped `sql.ErrNoRows` without translating to `ErrNotFound`, breaking the port contract. ### Medium - `Create` now returns the created entity via `Get` instead of empty `Course{}`. - Fixed prepared statement leak in `Organization.Create`. - Unified `time.Now()` to `time.Now().UTC()` for consistency across repos.

fix(issue-16): fix critical transaction bug and high-severity repository issues ca32d865b2

C1: CreateBatch shadowed err with := in loop, causing partial commits on
    failure. Fixed with named return and execErr loop variable.
H1: OrderBy concatenated raw into SQL query. Added whitelist validation.
H2: Organization.List dropped query args in SelectContext call.
H3: CourseRepository.Get wrapped sql.ErrNoRows without translating to
    ErrNotFound, breaking the port contract.
Medium: Create now returns the created entity via Get; fixed prepared
    statement leak in Organization.Create; unified time.Now() to UTC.

Use map[string]struct{} for fields white-list.

Use `map[string]struct{}` for fields white-list.

refactor: use map[string]struct{} for allowedOrderBy whitelist 590fed23ca

Per review feedback on PR #17, comment #137: use map[string]struct{}
(set semantics) instead of map[string]bool for the ORDER BY field
whitelist. Updates the lookup to comma-ok idiom.

Review Responses

[sqlite_course_repository.go:81] - @frx:

Use map[string]struct{} for fields white-list.

Done. Changed map[string]bool → map[string]struct{} for the allowedOrderBy whitelist (set semantics, zero-value footprint). Updated the lookup to the comma-ok idiom (if _, ok := allowedOrderBy[key]; !ok) since struct{} can't be used as a boolean directly.

Commit 590fed2 pushed to this branch.

[internal/kurious/adapters/sqlite_course_repository.go] - @frx:

Use map[string]struct{} for fields white-list.

Done. Changed map[string]bool to the idiomatic map[string]struct{}{} with the comma-ok lookup pattern (if _, ok := allowedOrderBy[params.OrderBy]; !ok). Committed in 590fed2, pushed to fix/issue-16.

All feedback from both reviews has been addressed. Ready for re-review.

[internal/kurious/adapters/sqlite_course_repository.go] - @frx:

Use map[string]struct{} for fields white-list.

Done. Changed allowedOrderBy from map[string]bool to map[string]struct{} — zero-size value type is idiomatic Go for set-style membership checks. Lookup updated to comma-ok form: if _, ok := allowedOrderBy[params.OrderBy]; !ok.
