• Ticket: [ENG-9818]
• Feature flag: collectionSubmissionWithCedar (environment config)

Purpose

When the collectionSubmissionWithCedar feature flag is active, switch the collection discover page (/collections/<id>/discover) from the legacy OSF v2 search API to the shtrove API (/trove/index-card-search), reusing the shared GlobalSearchComponent already used by preprint, registry, and institution search pages. If the collection provider has a required_metadata_template, derive additional filter facets from that CEDAR template's fields and append them to the search filter panel.

Summary of Changes

global-search store

• Added SetExtraFilters action and extraFilters: DiscoverableFilter[] state field (default [])
• updateResourcesState now merges API-returned filters with extraFilters, deduplicating by key — extra filters survive repeated FetchResources calls
• ResetSearchState clears extraFilters (included in GLOBAL_SEARCH_STATE_DEFAULTS)

CedarTemplateFilterMapper (new — src/app/shared/mappers/filters/)

• Static fromTemplate(template: CedarTemplate): DiscoverableFilter[]
• Iterates _ui.order, skips fields with blank/missing labels, maps each to a DiscoverableFilter with operator: AnyOf
• Spec covers: normal mapping, empty/whitespace labels, absent keys, order preservation, empty template

CollectionsDiscoverComponent

• Reads environment.collectionSubmissionWithCedar once at construction as readonly useShtrovSearch
• In shtrove mode: dispatches SetDefaultFilterValue('isContainedBy', apiDomainUrl/v2/collections/<id>/) to scope trove results to the collection; if provider has requiredMetadataTemplate, maps its fields via CedarTemplateFilterMapper and dispatches SetExtraFilters
• Template: @if (useShtrovSearch) renders <osf-global-search [searchControlInput]="searchControl" /> (guarded by defaultSearchFiltersInitialized); @else keeps existing <osf-collections-main-content />
• Legacy effects (getCollectionDetails, URL query sync, debounced search binding) are skipped in shtrove mode
• On destroy: always calls clearCollections; additionally calls resetSearchState in shtrove mode
• Refactored monolithic setupEffects() into focused private methods (setupBrandingEffect, setupShtrovSearchEffect, setupCollectionDetailsEffect, setupUrlSyncEffect, setupLegacySearchEffect)
