Closes #459

Operator workspace

• Compact, width-constrained title/tenant/actions header with the main management tabs immediately below it.
• Collapsed tenant rollout eligibility and release automation details; important attention indicators remain visible and policy guidance remains accessible.
• Local imports promoted to a top-level tab, with a direct catalogue shortcut, independent refresh, 20/50/100 pagination, approval/retry/cancel/source checks and the existing confirmed deletion/cleanup workflow.
• All management tables default to 20 rows and offer 20/50/100. GitHub catalogue page composition respects the existing cached 20-row API and its 600-entry discovery boundary; page-size and channel changes reset to page one.
• Fence cancelled/superseded catalogue reads and separate local import errors from upstream discovery. Preserve tab-dependent activity streaming, draft navigation guards, tenant policy and release verification.

Focused tests

• Page traversal across 20/50/100 boundaries without missing/duplicated entries; single forced prefix refresh; partial discovery, scan bounds and cancellation.
• Component tests for collapsed guidance, dedicated imports navigation, page-size reset/retention and unchanged deletion blockers/confirmation/navigation safety.
• Existing regression groups and CI gates remain enabled.

Beta preparation

Directory.Build.props is updated to 0.1.3-beta.4, the next unused beta tag at preparation time. This includes the previously merged inventory reliability/UX work (#456). Release notes are under the existing canonical release-notes category.

Validation will be recorded from the existing hosted PR workflow. Merge only after CI passes. The owner explicitly requests publication after merge; a version bump/PR merge alone does not establish published artifacts. No production deployment is requested.

Validation completed

Validated head 8394e29686bda9477b7c3969bc077f8d55c16e4a against main 785c2ba22b1dc661c57fb7eb032be5673eb252a3 in Public PR validation run 41318765281.

All required jobs passed: Public disclosure gate, Source and release contracts, .NET build and tests, and the final PR validation gate.

• Product version authority: 22 projects verified at 0.1.3-beta.4.
• Release-configuration solution build: passed, 0 errors; compiler/analyzer warnings remain. Build duration 3m05s.
• Web components: 682 passed, 0 failed, 0 skipped (43s stage).
• Core: 4,724 passed, 0 failed, 0 skipped (815s stage).
• API integration: 36 passed, 0 failed, 0 skipped (323s stage, overlapping Core).
• Total: 5,442 passed; all three TRX receipts validated. No tests, assertions or CI gates disabled. The build/test job completed in approximately 18m21s, within the existing 20-minute limit.

New coverage exercises 20/50/100 catalogue boundaries, incomplete discovery without skipping unloaded rows, single forced refresh, cancellation, collapsed workspace guidance, dedicated Local imports, page-size reset/retention and preserved deletion confirmation/blocker/navigation safeguards.

Test receipts are retained as dotnet-test-results (CI evidence, not release binaries).

The owner requested beta publication after merge. The source version and release notes are prepared; publication remains not started and is tracked in #461 because this session's connector does not expose tag/release creation or workflow dispatch. No production deployment or live browser/native acceptance was performed.

Post-merge main validation passed

The merged commit 0754a75bd5f6462dc40df45d5dc6d061d840dbbb passed all required jobs in main-push validation 41320743148, including the final validation gate.

Downloaded and verified the retained TRX archive against its GitHub-reported SHA-256 47e2285945f7c855fb5dde62e3548e74afba2d26c5db7ba418010e439c544c51. Main results match the PR run: 682 Components + 4,724 Core + 36 API = 5,442 passed, with zero failures or skipped/not-executed tests. Main regression stage durations: Components 36s, Core 668s, API 234s (Core/API overlap).

Main test receipts are CI evidence only. The merged tree also exactly matches the tree tested by the successful PR run.

Implementation, merge and PR/main CI are complete. The product source version is 0.1.3-beta.4. Release publication remains unstarted, tracked in #461; no tag or distributable beta assets have been created by this session.
