This session (frontend focus):
- Rebuild /apps/new as a 4-step wizard (Basics → Configure → Trigger → Review):
WizardRail, SourceKindPicker card grid, AppManifest review, per-step validation,
ConfirmDialog-based unsaved-changes guard.
- Extract lib/workload/sourceForms.ts (single source of truth for source_config)
+ {Image,Compose,Static,Dockerfile}SourceForm + StaticDiscoveryWizard; fold the
/apps/[id] edit form onto the same components (removes the duplication). Add
vitest + sourceForms unit tests.
- Branch preview environments UI: /chain is_preview/preview_branch + a Preview
environments panel on /apps/[id] (per-branch URLs, ConfirmDialog teardown, armed
state); RegistryImagePicker on the registry trigger and the image source.
- Fixes: image-inspect 404 -> admin-gated POST /api/discovery/image/inspect;
conflict-panel blur flicker; friendly localized discovery errors; CPU/Memory
label hints; dashboard + /apps "Total workloads" count only source_kind workloads
(drop stale trigger_kind gate); NPM cert/access-list name cache; EntityPicker
empty-list guard.
- Update CLAUDE.md frontend conventions + add a Build & Test section.
Also captures pre-existing in-progress platform work (not from this session):
workload notifications, Prometheus metrics export, store lockfile, health probes,
backup hardening, and related store/webhook/scheduler changes.
