- with/without host ID (prefix selection)
- derives ID from service name with sanitization
- special chars replaced with dashes
- preserves alphanumeric, underscore, hyphen
- trims leading/trailing dashes/underscores
- truncates long IDs to 32 chars
- fallback to 'service' when empty
- dockerServiceResourceID 23.8%→100%
- returns name when present
- returns trimmed name
- returns truncated ID when name empty (first 12 chars)
- returns full short ID when < 12 chars
- returns 'service' when both empty/whitespace
- prefers name over ID
- dockerServiceDisplayName 33.3%→100%
- nil thresholds get defaults (CPU 95, Memory 92, Disk 95)
- low thresholds raised to minimum relaxed values
- high thresholds unchanged
- clear adjusted when too close to trigger
- original config unchanged (no mutation)
- alerts package coverage improvement: applyRelaxedGuestThresholds 75%→93.8%
Cover all branches: disabled rate limit (zero/negative MaxAlertsHour),
under limit, at limit blocking, separate limits per alertID, old entry
cleanup, and mixed old/recent entries. Coverage improved from 71.4% to 100%.
Cover both branches: single alert template (isSingle=true with 1 alert)
and grouped alert template (isSingle=false or multiple alerts). Tests
verify subject format, HTML structure, and text body generation.
Coverage improved from 66.7% to 100%.
Cover all branches: nil/empty TimeThresholds, direct match, canonical key
matching (vm→guest, container→guest), "all" fallback, specific match
precedence, and global threshold fallback. Coverage improved from 85.7% to 100%.
Cover all branches: user without realm gets @pam appended, user with
realm unchanged, token auth skips user modification, empty user handling,
and fingerprint/verifySSL preservation. Coverage improved from 66.7% to 100%.
Cover all branches: disabled state, invalid timezone fallback, day not
enabled, invalid start/end time parsing, overnight window spanning
midnight, and normal daytime window. Coverage improved from 61.5% to 96.2%.
Cover all branches of flapping detection: disabled state, below/at/above
threshold, already-flapping state (no suppression update), and window
expiry pruning. Coverage improved from 61.9% to 95.2%.
The expanded container/service drawer cards were overflowing
horizontally instead of wrapping when the table had overflow-x-auto.
Adding overflow-hidden to the drawer's outer container forces the
flex-wrap to work correctly.

- Test different instance and node (full format)
- Test same instance and node (short format)
- Test empty instance defaults to node
- Test whitespace trimming
- Improves BuildGuestKey coverage from 71.4% to 100%
Add test case for malformed IPv6 URL that triggers url.Parse error.
Improves coverage from 90% to 95%. The remaining 5% is a template
Execute error path that's effectively unreachable with current types.
When tasks have identical NextRun and Priority, the Less function
falls back to comparing InstanceName alphabetically. Add test to
cover this edge case branch, improving Less coverage to 100%.
Tests for Proxmox client authentication error handling:
- authHTTPError.Error: message formatting based on status code
(401/403 include status in message, others don't)
- shouldFallbackToForm: determines when to retry with form encoding
(triggers on 400/415, not on auth errors or server errors)
16 test cases covering all code paths.
Tests for alert filter evaluation logic:
- evaluateVMCondition: metric/text/raw conditions for VMs
- evaluateContainerCondition: same for containers
- evaluateFilterStack: AND/OR logic with multiple conditions
- evaluateFilterCondition: type dispatch
74 test cases covering:
- All metric types (cpu, memory, disk, diskread, diskwrite, network)
- All comparison operators (>, <, >=, <=, =, ==)
- Text search fields (name, node, vmid) with case insensitivity
- Raw text search across multiple fields
- Value type conversions (int to float64)
- Edge cases (zero, empty, invalid types)
Coverage improved from 46.8% to 48.9%.

Tests for all 9 functions handling Docker host identification:
- uniqueNonEmptyStrings: dedupe with order preservation
- sanitizeDockerHostSuffix: string cleaning for IDs
- tokenHintFromRecord: redacted token hints
- dockerHostIDExists: ID existence check
- dockerHostSuffixCandidates: candidate suffix generation
- fallbackDockerHostID: hash-based ID generation
- findMatchingDockerHost: host matching by various criteria
- generateDockerHostIdentifier: unique ID generation with suffixes
- resolveDockerHostIdentifier: main resolver orchestration
86 test cases covering edge cases (nil, empty, whitespace), Unicode
handling, and complex matching scenarios.
Tests cover nil/empty inputs, basic field copying, time fields
(CreatedAt/UpdatedAt with nil and zero value handling), update status
conversion, endpoint ports, and labels cloning.
Add comprehensive error handling tests for two pure functions:
renderWebhookURL (8 new test cases):
- Empty/whitespace URL template validation
- Invalid template syntax (unclosed braces, undefined functions)
- Template producing empty URL
- Missing scheme or host in rendered URL
UpdateAllowedPrivateCIDRs (expanded from 8 to 29 cases):
- Invalid IP addresses (garbage, out of range, malformed)
- Invalid CIDR notation (prefix too large, negative, non-numeric)
- Malformed strings (double slash, invalid IP with valid prefix)
- Success cases for valid IPv4/IPv6 CIDRs and bare IPs
