Keep the last verified version snapshot during a failed background poll, then clear the warning when the endpoint recovers.

Why this matters

A transient API restart currently removes the update/version information already shown to the operator.

Root cause: The poll's catch handler replaces the last successful version with null and successful recovery does not clear the prior error.

Behavioral invariant: A failed observation is not evidence that the previous version disappeared; a newer successful receipt replaces it and clears the error.

Implementation and compatibility

Preserve version state on failure and clear error on success. Tests cover network, HTTP and JSON failures plus a previously dismissed update and a genuinely newer release.

This updates the original canonical PR onto public-beta at 3c186f3f12ba21dad7b7266ec5449393529abb00; it does not create a competing replacement. The shared browser code applies to Linux, macOS and Windows installations. There is no persisted schema migration. Rollback is a revert/rebuild of the dashboard; server lifecycle and authorization remain backend-owned.

Overlap check

Searched open and closed upstream PRs by semantic keywords and inspected the complete 1,010-entry public-beta changed-file index on 2026-09-16. Searched production paths: ods/extensions/services/dashboard/src/hooks/useVersion.js.

Relevant same-file results: No public-beta PR touched these production files in the all-state changed-file index.

Retains #3046 as the original canonical change. Browser-storage access is a separate known concern (#2780), not folded into this failure-retention fix.

Regression and validation

Candidate commit: 6eb08c2986b4db2bb58fed90029f68573b1fd75f.

• From ods/extensions/services/dashboard: npx vitest run src/hooks/__tests__/useVersion.test.js — 9 passed.
• Unmodified beta production code fails all 3 new retention/recovery scenarios; candidate passes 9 tests.
• Changed-file ESLint, git diff --check, and pre-commit secret/private-key/large-file checks pass. Existing lint warnings are not errors.
• Clean beta baseline: full dashboard 1,232 tests passed, lint and production build passed on Windows Node 24.14.1. CI uses Node 20 and validates Linux/macOS/Windows. No browser-on-hardware or live GPU/model-service claim is made by these mocked HTTP/UI tests.
• Broad make gate on a Linux-native clean beta checkout stops at the existing no-sudo Docker fallback contract (2 failures under the root test environment). The Windows-mounted copy additionally exposed CRLF-sensitive Hermes fixture assertions. Full-tree pre-commit finds existing dummy private-key test fixtures and Windows lacks awk for the heredoc hook; the candidate's scoped secret/key/size hooks pass. These limitations are not represented as successful runtime validation.

Review readiness and batch integration

Implementation and focused checks are complete; this PR is Ready for independent review. CI limits below remain visible and no upstream merge or deployment has been performed.

Exact-head CI at 2026-09-16T13:33:01.8060875Z for 6eb08c2986b4db2bb58fed90029f68573b1fd75f: 36 successful checks; 1 failed; 0 pending; 4 skipped review/security jobs (not counted as passes). distro: cachyos.

The failed CachyOS job stopped while installing checkout prerequisites: the distro repository signature was invalid, before this candidate was checked out. Later candidates passed the same distro job, but this exact head remains red. GitHub refused the failed-run rerun with “Must have admin rights to Repository.” A maintainer rerun is still required; no signature checks were disabled.

All 20 exact candidate commits were merged into synthetic integration d3c05b74ddfa from beta 3c186f3f12ba21dad7b7266ec5449393529abb00. That exact head passed 1,279 tests across 167 files, full ESLint (0 errors; 618 existing warnings), production build, scoped secret/private-key/large-file hooks and git diff --check on Windows Node 24.14.1. These are mocked browser/HTTP checks, not live GPU or deployment evidence.

Verified merge order: #3044 → #3046 → #3025 → #3038 → #3043 → #3050 → #3312 → #3313 → #3315 → #3316 → #3376 → #3041 → #3042 → #3051 → #3065 → #3062 → #3039 → #3040 → #3049 → #2780.

Merge guidance for this scope: With #2780, production code merges cleanly; retain the union of retention/recovery and denied-storage tests.

The only textual conflicts inside the selected batch were #3316/#3040 (download hook plus tests) and #3046/#2780 (tests only). Use the linked integration commit as the reviewed resolution reference. Each PR remains independently based on beta; if merging them separately or squashing, reapply the relevant resolution and rerun affected suites. Outside-batch checks used git merge-tree only: #3846/#3848/#3841/#3843 merged textually, while #3803/#4356/#5276/#5125 conflicted. Textual compatibility alone does not establish runtime compatibility.

Additional clean-beta Linux checks: make lint, make smoke, and make simulate pass. make bats has five baseline environment failures (WSL classification, root permissions/preflight, and a 15 GB free-space boundary), in addition to the full-gate limitations described above. Installer/backend sources are unchanged by this batch. Rollback remains a revert and dashboard rebuild; no stored schema or backend lifecycle migration was introduced.
