Per architecture_comparison.md universal-win for Go side: ports the
Rust crates/validator/src/staffing/ to internal/validator/. Production
safety net Go was missing — FillValidator catches phantom worker IDs
+ status/blacklist/geo/role mismatches; EmailValidator catches
SSN-shape PII + salary disclosure + wrong-target name in email/SMS
drafts.
Files:
- types.go: Artifact (FillProposal | EmailDraft), Validator interface,
WorkerLookup interface, ValidationError + Finding + Severity
- lookup.go: InMemoryWorkerLookup with case-insensitive ID lookup
- fill.go: FillValidator — schema → completeness → cross-roster
(phantom ID / status / blacklist / geo / role)
- email.go: EmailValidator — schema → length → PII (SSN + salary)
→ worker-name consistency
- fill_test.go + email_test.go: 24 tests covering happy path +
every error variant + the load-bearing edge cases (phone-pattern
not flagged as SSN, flanking-digit guard rejects extended
numeric runs)
Validator names match Rust (staffing.fill / staffing.email) so
cross-runtime audit logs share the same identifier. PII scanners
(containsSSNPattern, containsSalaryDisclosure) ported byte-for-byte
so a draft flagged by one runtime is flagged by the other.
Caveat: the Rust validator crate also has parquet_lookup.rs (loads
workers_500k.parquet at startup) and playbook.rs (additional
checks). Those weren't ported in this wave — only the two
load-bearing validators that were named in the comparison doc.
Closes one of the two universal-win items for Go side. The other
(materializer port) remains deferred — it's a bigger surface change
and depends on transforms.ts source-class adapters.
