+- **#206** — STATUS.md updated for 2026-06-05 sprint planning cycle (this entry). Last-updated date set to 2026-06-05.
+- **Completed outcomes from 2026-06-04 sprint planning cycle recorded:**
+  - Issue #204 (smoke-tests): reopened and relabeled `blocked` — was prematurely closed while prerequisites (DNS #33/#150, Flux #2/#187) are still open.
+  - ROADMAP cross-reference: all 18 unchecked items confirmed grounded in open issues (zero gaps).
+  - Staleness check: oldest open issue is #2 from 2026-05-18 (18 days, under 30-day threshold — no closures).
+  - Label audit: no label changes required — all existing priority/complexity labels are correct.
+- **Critical path confirmed:** Operator must (1) create `0xWheatyz/api-company` (#47), (2) merge upstream Talos PR #14 (#187) to activate Flux, (3) configure DNS (#33, #106, #150).
+- **`kustomize build flux/` = PASS** — no regressions.
+- **0 open PRs** — nothing to review or merge.

   - **#204** (smoke tests): ❌ BLOCKED — all HTTP endpoints timeout; DNS not configured; kubectl unreachable.
