# TASKS
| Task | Owner(s) | Depends on | Notes |
|---|---|---|---|
|Ecosystem fetchers (npm, pypi, maven, go, crates)|BE-Conn-OSV|Source.Common|**DONE** – archive fetch loop iterates ecosystems with pagination + change gating.|
|OSV options & HttpClient configuration|BE-Conn-OSV|Source.Common|**DONE** – `OsvOptions` + `AddOsvConnector` configure allowlisted HttpClient.|
|DTO validation + sanitizer|BE-Conn-OSV|Source.Common|**DONE** – JSON deserialization sanitizes payloads before persistence; schema enforcement deferred.|
|Mapper to canonical SemVer ranges|BE-Conn-OSV|Models|**DONE** – `OsvMapper` emits SemVer ranges with provenance metadata.|
|Alias consolidation (GHSA/CVE)|BE-Merge|Merge|DONE – OSV advisory records now emit GHSA/CVE aliases captured by alias graph tests.|
|Tests: snapshot per ecosystem|QA|Tests|DONE – deterministic snapshots added for npm and PyPI advisories.|
|Cursor persistence and hash gating|BE-Conn-OSV|Storage.Mongo|**DONE** – `OsvCursor` tracks per-ecosystem metadata and SHA gating.|
|Parity checks vs GHSA data|QA|Merge|DONE – `OsvGhsaParityRegressionTests` keep OSV ↔ GHSA fixtures green; regeneration workflow documented in docs/19_TEST_SUITE_OVERVIEW.md.|
|Connector DI routine & job registration|BE-Conn-OSV|Core|**DONE** – DI routine registers fetch/parse/map jobs with scheduler.|
|Implement OSV fetch/parse/map skeleton|BE-Conn-OSV|Source.Common|**DONE** – connector now persists documents, DTOs, and canonical advisories.|
