# Tasks

- [x] Remove VeloPack packaging from release workflow.
- [x] Keep signed FileMap path as interim compatibility fallback.
- [x] Remove launcher/runtime Velopack branching.
- [x] Add `phainon.yml` for PDCC publish configuration.
- [ ] Add PDCC installation + publish steps in `release.yml` (deferred; active path is GitHub Actions PloNDS static publish).
- [x] Upload app payload artifacts for PloNDS delta generation in release build jobs.
- [x] Publish PloNDS metadata + sha256 object repo to S3 path root `lanmountain/update/`.
- [x] Mirror installers to `lanmountain/update/installers/<platform>/<version>/`.
- [x] Keep update source compatibility (`pdc`/`stcn` normalize to active PloNDS source).
- [x] Add PloNDS static payload model into host update check result.
- [x] Add host download path for PloNDS payload (`plonds-filemap.json` + signature + object repo).
- [x] Add launcher PloNDS FileMap apply path with rollback-compatible semantics.
- [x] Keep old `files.json + update.zip` path behind compatibility fallback.
- [x] Keep rollback deployment directories after successful apply and prune by bounded retention.
- [x] Return structured failure when manual rollback snapshot source is missing.
- [x] Verify static S3 layout, filemap/signature, distribution, latest pointer, and at least one object in CI workflows.
- [x] Add regression tests for PloNDS success rollback, hash-failure auto rollback, missing rollback source, static NS3 manifest, and manifest field mapping.
- [ ] Attach live CI run proving the full release matrix passes.
- [ ] Verify N-1 -> N incremental update on Windows x86 and Linux x64 in release artifacts.
