The registry lists tags lexically after this value, so you + can skip large numbers of irrelevant earlier tags (e.g. tens of thousands of + digest tags) without fetching them. It is not a real tag name — any string + works, e.g. `x86_64-u~` jumps straight to the `x86_64-v*` tags. +- `maxScan` (optional) caps how many tags are fetched per repository before + filtering.

Available variables: {{.Registry}}, {{.Repository}}, {{.Tag}} Default (when unset): "{{.Registry}}/{{.Repository}}:{{.Tag}}" Example: "{{.Registry}}/{{.Repository}}@{{.Tag}}" (if tags are actually digests) | +| Start | `start` | `string` | ✓ | | Start is the inclusive start time in "HH:MM" format (24-hour, local time). Example: "09:00" | +| End | `end` | `string` | ✓ | | End is the exclusive end time in "HH:MM" format (24-hour, local time). Example: "17:00" | + +### TimeWeightedAggregateSignalConfig + +TimeWeightedAggregateSignalConfig configures the timeWeightedAggregate signal type. Each sample value is multiplied by the weight of the matching time window before aggregation. + +| Field | JSON | Type | Required | Default | Description | +|-------|------|------|----------|---------|-------------| +| Method | `method` | `AggregationMethod` | ✓ | | Method is the aggregation function applied after weighting (currently only "sum" is meaningful).

Example: "Europe/Berlin", "America/New_York", "UTC" | +| DefaultWeight | `defaultWeight` | `resource.Quantity` | ✓ | | DefaultWeight is applied to samples that do not fall in any configured window. Use "0" to exclude off-hours samples entirely. | +| Windows | `windows` | `[]TimeWeightedWindow` | ✓ | | Windows is the list of hour-of-day windows with associated weights. | + +### TimeWeightedWindow + +TimeWeightedWindow defines a wall-clock hour range and its weight factor. + +| Field | JSON | Type | Required | Default | Description | +|-------|------|------|----------|---------|-------------| +| StartHour | `startHour` | `int32` | ✓ | | StartHour is the inclusive start of the window in local time (0–23). | +| EndHour | `endHour` | `int32` | ✓ | | EndHour is the exclusive end of the window in local time (1–24). | +| Weight | `weight` | `resource.Quantity` | ✓ | | Weight is the factor applied to sample values within this window. Use "1.0" for full weight, "0.3" for partial, "0" to exclude. | + +### WeightedSumRankingConfig + +WeightedSumRankingConfig configures the weightedSum ranking strategy. Score = Σ weight_k * normalize(signal_k(image)). + +| Field | JSON | Type | Required | Default | Description | +|-------|------|------|----------|---------|-------------| +| Normalize | `normalize` | `NormalizeMethod` | ✓ | `minMax` | Normalize selects the normalization method applied to each signal before weighting. Currently only "minMax" is supported. Enum: `minMax` | +| MissingSignal | `missingSignal` | `MissingSignalBehavior` | ✓ | `zero` | MissingSignal controls behavior when an image has no value for a required signal. "zero" treats missing as 0; "drop" removes the image from ranking. Enum: `zero`,`drop` | +| Terms | `terms` | `[]WeightedSumTerm` | ✓ | | Terms is the list of signals and their weights. | + +### WeightedSumTerm + +WeightedSumTerm defines one signal contribution in a weightedSum ranking. + +| Field | JSON | Type | Required | Default | Description | +|-------|------|------|----------|---------|-------------| +| Signal | `signal` | `string` | ✓ | | Signal is the name of the signal to include in the weighted sum. Must match a signals[].name within the same policy. | +| Weight | `weight` | `resource.Quantity` | ✓ | | Weight is the factor applied to the normalized signal value. All weights should be non-negative; they do not need to sum to 1. Example: "0.7" | + +### WindowAggregateSignalConfig + +WindowAggregateSignalConfig configures the windowAggregate signal type. Exactly one of relativeWindow or (window + timezone) must be set. + +| Field | JSON | Type | Required | Default | Description | +|-------|------|------|----------|---------|-------------| +| Method | `method` | `AggregationMethod` | ✓ | | Method is the aggregation function applied to the windowed samples. Enum: `sum`,`count`,`avg`,`max`,`min` | +| RelativeWindow | `relativeWindow` | `*metav1.Duration` | — | | RelativeWindow aggregates only samples from the last N duration before now. Mutually exclusive with window + timezone. Example: "2h" (last 2 hours) | +| Timezone | `timezone` | `string` | — | | Timezone is the IANA time zone for evaluating wall-clock window boundaries. Required when window is set. | +| Window | `window` | `*TimeOfDayWindow` | — | | Window defines fixed wall-clock start/end times within each day.
