# Completed Tasks

|Review KEV JSON schema & cadence|BE-Conn-KEV|Research|**DONE** – Feed defaults lock to the public JSON catalog; AGENTS notes call out daily cadence and allowlist requirements.|

|Fetch & cursor implementation|BE-Conn-KEV|Source.Common, Storage.Mongo|**DONE** – SourceFetchService drives ETag/Last-Modified aware fetches with SourceState cursor tracking documents + catalog metadata.|

|DTO/parser implementation|BE-Conn-KEV|Source.Common|**DONE** – `KevCatalogDto`/`KevVulnerabilityDto` deserialize payloads with logging for catalog version/releases before DTO persistence.|

|Canonical mapping & range primitives|BE-Conn-KEV|Models|**DONE** – Mapper produces vendor RangePrimitives (due dates, CWE list, ransomware flag, catalog metadata) and deduplicated references.|

|Deterministic fixtures/tests|QA|Testing|**DONE** – End-to-end fetch→parse→map test with canned catalog + snapshot (`UPDATE_KEV_FIXTURES=1`) guards determinism.|

|Telemetry & docs|DevEx|Docs|**DONE** – Connector emits structured logs + meters for catalog entries/advisories and AGENTS docs cover cadence/allowlist guidance.|

|Schema validation & anomaly surfacing|BE-Conn-KEV, QA|Source.Common|**DONE (2025-10-12)** – Wired `IJsonSchemaValidator` + embedded schema, added failure reasons (`schema`, `download`, `invalidJson`, etc.), anomaly counters (`missingCveId`, `countMismatch`, `nullEntry`), and kept `dotnet test src/Concelier/StellaOps.Concelier.PluginBinaries/StellaOps.Concelier.Connector.Kev.Tests` passing.|

|Metrics export wiring|DevOps, DevEx|Observability|**DONE (2025-10-12)** – Added `kev.fetch.*` counters, parse failure/anomaly tags, refreshed ops runbook + Grafana dashboard (`docs/modules/concelier/operations/connectors/cve-kev-grafana-dashboard.json`) with PromQL guidance.|

|FEEDCONN-KEV-02-003 Normalized versions propagation|BE-Conn-KEV|Models `FEEDMODELS-SCHEMA-01-003`, Normalization playbook|**DONE (2025-10-12)** – Validated catalog/date/due normalized rules emission + ordering; fixtures assert rule set and `dotnet test src/Concelier/StellaOps.Concelier.PluginBinaries/StellaOps.Concelier.Connector.Kev.Tests` remains green.|
