Site workers currently use a default of 3m regardless of Site Agent configuration. The Site Agent's collection interval is configurable through TEMPORAL_INVENTORY_SCHEDULE and runs as low as @every 1m where REST and Core share a cluster. This PR addresses this disconnect by allowing Site Agent to report it's interval instead.

SKU and Operating System deletion steps were missing the staleness guard, they are fixed here too.

Review Change Stack

Summary by CodeRabbit

  • New Features

    • Site inventory schedules can now be reported by each Site Agent.
    • Site records display Site Agent version and inventory interval information.
    • Added support for publishing combined Core and Site Agent build details.
    • Added a V2 inventory workflow while preserving compatibility with the existing workflow.
  • Bug Fixes

    • Improved stale-inventory handling using site-specific schedules and clock-skew protection.
    • Prevents recently created inventory records from being deleted prematurely.
    • Inventory collection now runs more frequently by default.

Walkthrough

Site Agent inventory schedules now use shared resolution and report their cadence. Core stores the reported interval and Site Agent metadata. A V2 workflow publishes and persists this data. Inventory reconciliation uses site-specific stale thresholds.

Changes

Inventory cadence and staleness

Layer / File(s) Summary
Staleness contract and persistence
rest-api/common/pkg/util/workflow.go, rest-api/db/pkg/db/model/site.go, rest-api/db/pkg/migrations/..., rest-api/proto/core/src/v1/inventory.proto
Adds default and buffered staleness intervals, persists InventoryIntervalSeconds, and adds inventory metadata messages.
Shared schedule resolution and reporting
devspace.yaml, rest-api/site-agent/pkg/components/managers/*/cron.go, rest-api/site-agent/pkg/components/managers/workflow/utils.go, rest-api/site-agent/pkg/components/managers/site/publisher.go, rest-api/site-workflow/pkg/util/*
Centralizes inventory schedule selection. Site Agent publishers derive and report the interval.
V2 inventory workflow
rest-api/site-workflow/pkg/activity/site.go, rest-api/workflow/pkg/workflow/site/update.go, rest-api/workflow/cmd/workflow/main.go, rest-api/workflow/pkg/activity/site/*
Adds UpdateSiteConfigInventoryV2, preserves V1 compatibility, publishes combined build information, and persists Site Agent version and interval data.
Reconciliation guards
rest-api/workflow/pkg/activity/*
Replaces global interval checks with Site.IsTimeWithinStaleInventoryThreshold. Tests cover default and site-specific intervals, deferred deletion, and updated interval names.

Estimated code review effort: 4 (Complex) | ~60 minutes

Merge Risk: 🔴 Critical · up to ac0b3

This PR is not merge-ready because it contains a compile-breaking alias reference and can incorrectly delete valid SKU records when delayed inventory receipts are processed; removing exported schedule constants may also break external consumers.

Preserve the exported schedule constants.

The change removes InventoryDefaultSchedule from the dpuextensionservice, site, and tenant packages. External consumers of these exported identifiers will no longer compile. Add deprecated aliases such as const InventoryDefaultSchedule = wfmgr.InventoryDefaultSchedule in each original package, and apply the same fix to the other manager packages that removed this identifier.

Use the surviving workflow utility alias.

These lines still reference cwutil.DefaultInventoryReceiptInterval, but the change removes the rest-api/workflow/pkg/util import. This leaves cwutil undefined at compile time. Use cwu.DefaultInventoryReceiptInterval in both timestamp expressions, or retain the removed import.

Use a Core-controlled timestamp for the SKU staleness guard.

sk.Created is persisted from the Site-reported Sku.Created value. The SKU tests verify this behavior. A SKU first stored from a newer receipt can therefore have an old creation timestamp. If an older delayed receipt omits that SKU, this check treats it as stale and deletes it immediately.

Store a first-seen timestamp in Core, or preserve a database insertion timestamp for this guard. Add an out-of-order receipt test with an old source Created value.

As per path instructions, review rest-api/workflow/** for safe external side effects.
