Endpoint-Specific Engineering Notes

This section is intentionally unique for POST /api/update/check. Focus area: triggering version check and interpreting availability state. When integrating OpenHaldex at scale, this endpoint should be treated as a dedicated workflow step rather than a generic HTTP action.

Operational scenario: Run check only after network readiness is confirmed; then branch UI to install or no-update paths.

Domain vocabulary: check-trigger, version-compare, manifest-read, availability-flag, check-timestamp, update-candidate, preinstall-gate, network-prereq, release-match, channel-check.

Common Mistakes for This Endpoint

Checking without connectivity
Treating transient errors as permanent
Not clearing previous check messages

Practical Validation Pattern

Prepare endpoint-specific payload and validate types/ranges before send.
Execute POST /api/update/check and capture status code + raw response.
Parse response and apply only validated fields to UI state.
Run a follow-up read (usually /api/status) to verify runtime convergence.
Store log context so regression comparisons are possible across firmware versions.

Reference Snippet

await fetch('/api/update/check',{method:'POST'});

Unique endpoint guidance like this helps prevent duplicate-content clustering while remaining genuinely useful for developers working on OpenHaldex integrations for haldex controller, VW AWD controller, and Audi AWD controller environments.
