Sync malware advisories into GitLab database
We have to Sync the malware advisories data from the private bucket which is being handled in https://gitlab.com/groups/gitlab-org/-/work_items/20538 into GitLab.
### Unknowns
1. Auth for connecting to the private bucket for performing the data sync.
- Can use ADS and cloud connector framework to get the token to communicate with the endpoint. Details available in https://gitlab.com/gitlab-com/content-sites/handbook/-/merge_requests/18229#note_3159494508
### Implementation pieces
1. Tables and data model for the GLAM advisories.
2. Sync framework which ingests data into the tables.

## Work breakdown & structure
Following the [POC outcome](https://gitlab.com/gitlab-org/gitlab/-/work_items/596491#note_3437298702) ([!226660](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/226660), closed), the Rails sync is decomposed into the issues below, grouped by dependency wave (everything within a wave can be worked in parallel; `is_blocked_by` links are set on each issue). Live status is in the GLQL table below; MRs are called out per row.
**Issue status:** ✅ done · 🔄 in progress · 🚫 blocked · 📅 scheduled · ⏭️ not required.

GA-hardening follow-ups, deferred until after the core sync is validated — large-file handling (a single Sidekiq job can't run long — [job-duration limit](https://docs.gitlab.com/development/sidekiq/#job-duration-limit) — and an `/all` snapshot decompresses to ~13× its compressed size), plus packaging/licensing and data-lifecycle items:

Seen locally: a `full` sync logged for `npm` (64 files) wrote **0** npm rows and 773 `nuget` rows, yet advanced npm's cursor to `chunk=63`, so npm then resolves to delta and its snapshot is never fetched.

### Related cross-epic change
- **Bulk multi-registry `/delta`** ([#603947](https://gitlab.com/gitlab-org/gitlab/-/work_items/603947), PDS epic gitlab-org&21313 / pmdb-distribution-service!27): one `/delta` poll covers all registries (~7× fewer PDS calls). The Rails side calls PDS **per-`purl_type`** today (using registry ids, [#607045](https://gitlab.com/gitlab-org/gitlab/-/work_items/607045)); the bulk multi-registry `/delta` is tracked as its own Wave 2 item [#607448](https://gitlab.com/gitlab-org/gitlab/-/work_items/607448) (MR [!247652](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/247652), connector foundation only so far). PDS lists unsupported registries in the bulk response body rather than `400`-ing the request, so a single bulk call tolerates them. It supersedes [#607370](https://gitlab.com/gitlab-org/gitlab/-/work_items/607370) (closed as duplicate). **No Rails DB change** — the existing per-PURL `pm_checkpoints` rows already supply the per-registry cursors.

- **PDS service** (`/all` + `/delta` endpoints, OIDC middleware) — PMDB ingestion epic gitlab-org&20538.
- **CVS scanning integration** (`GlobalMalwareAdvisoryScanWorker`, scanner) — companion MR [!226519](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/226519) / scanning epic.
- **Ingestion event emission** (`IngestedMalwareAdvisoryEvent`) — not required by the sync; it exists only to feed the downstream SBOM/CVS scanning integration, so it was dropped from [#602431](https://gitlab.com/gitlab-org/gitlab/-/work_items/602431) ([!240168](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/240168)) and is tracked in [#606613](https://gitlab.com/gitlab-org/gitlab/-/work_items/606613) under integration epic gitlab-org&21156.
### Future scope (tracked, not scheduled)
- [#604392](https://gitlab.com/gitlab-org/gitlab/-/work_items/604392) — widen `pm_checkpoints.sequence` + `first_sync_until` from `integer` to `bigint`. They hold Unix-second epoch cursors; `integer` overflows at **2038-01-19** (~11.6 yr headroom). Low priority; shared with public-advisory checkpoints so coordinate as a general `pm_checkpoints` change.
