fix: keep group visible as header for the running event

Search every text field with optional filters, keep result selection stable, and expose clearer match context and counts. Cover query parsing, matching, mixed-entry indexing, and the reveal flow.

+description: Review Ontime changes for concrete correctness, architecture, testing, routing, security, and maintenance issues. For GitHub Copilot review.
+---
+
+# Review Ontime changes
+
+Review as a maintainer. Find material defects, not speculative advice, style preferences, or generic checklists. Approve when no material issue remains.
+
+## Load relevant context
+
+Read the full diff, PR description, linked issue, tests, and nearby owning code. Then load only applicable guides:
+
+- Every non-trivial review: [change assessment](../../../docs/agent-guides/change-assessment.md)
+- Module placement, server layers, client state, shared packages: [architecture](../../../docs/agent-guides/architecture.md)
+- Tests or changed behaviour: [testing](../../../docs/agent-guides/testing.md)
+- Comments, abstractions, naming, complexity: [code quality](../../../docs/agent-guides/code-quality.md)
+- Authentication, external input, files, integrations, assets, secrets: [security](../../../docs/agent-guides/security.md)
+- Routes, URLs, websockets, authentication, cookies, presets, assets: [routing and cloud](../../../docs/agent-guides/routing-and-cloud.md)
+- Rundowns, timers, persistence, imports, cache, realtime: [domain invariants](../../../docs/agent-guides/domain-invariants.md)
+- Commands, imports, dependencies, formatting, CI claims: [workflow](../../../docs/agent-guides/workflow.md)
+
+Check a guide and nearby canonical code before citing an Ontime convention. Skip unrelated guides.
+
+## Review order
+
+1. Establish intent and affected runtime surfaces.
+2. Read tests first. Identify claimed behaviour and coverage.
+3. Trace implementation, errors, and state transitions.
+4. Check correctness/data integrity, security, architecture/testability, cloud routing, lifecycle/performance, maintainability.
+5. Verify claimed checks. Never claim unobserved results.
+
+Passing tests do not prove architecture, routing, comments, or error paths. Review changed behaviour only; include existing problems only when the diff worsens or relies on them.
+
+## Findings
+
+Report only concrete, actionable issues. Each finding: tight line range, direct defect, impact and trigger, smallest viable remedy when unclear.
+
+- **P0 — Critical:** data loss, exploitable vulnerability, broadly broken production. Blocks merge.
+- **P1 — High:** likely correctness failure or major supported-deployment regression. Blocks merge.
+- **P2 — Medium:** real edge-case defect, architecture regression, missing business-rule test, stale comment, meaningful maintenance risk. Normally blocks merge.
+- **P3 — Low:** local improvement with limited impact. No subjective style or tool-managed formatting.
+
+Order by priority. Prefer few high-confidence findings. No praise or checklist before findings. If none, say so and note verification gaps or residual risk.
+
+Then give one concise PR-level value/risk/complexity assessment. Never repeat it per finding.

+# Ontime agent guide
+
+Make the smallest maintainable change. Keep scope narrow. Inspect nearby code first. Reuse helpers and boundaries when semantics match.
+
+## Load only relevant guides
+
+- Commands, validation, formatting, imports, PRs: [workflow](docs/agent-guides/workflow.md).
+- Non-trivial planning, implementation, review: [change assessment](docs/agent-guides/change-assessment.md).
+- Module placement, server layers, client state, shared packages: [architecture](docs/agent-guides/architecture.md).
+- Tests or changed behaviour: [testing](docs/agent-guides/testing.md).
+- Comments, naming, abstractions, maintainability: [code quality](docs/agent-guides/code-quality.md).
+- Authentication, external input, files, integrations, assets, secrets: [security](docs/agent-guides/security.md).
+- Navigation, URLs, API paths, websockets, redirects, cookies, static assets: [routing and cloud](docs/agent-guides/routing-and-cloud.md).
+- Rundowns, timers, imports, persistence, cache, websockets: [domain invariants](docs/agent-guides/domain-invariants.md).
+
+Load multiple guides when needed. Skip unrelated guides for mechanical work.
+
+## Before handoff
+
+- Check the final diff for scope, stale comments, temporary code, redundant tests, generated files.
+- If work reveals a missing, stable, reusable system, domain, or product invariant, update its owning guide. Exclude guesses, one-off bugs, and implementation details.
+- Follow [workflow verification](docs/agent-guides/workflow.md). Report only observed results.

+# Ontime architecture
+
+Use for module placement or cross-boundary changes.
+
+## Direction
+
+Dependencies point toward pure domain logic:
+
+```text
+HTTP request
+  -> validation / router or controller
+  -> service orchestration
+  -> pure domain utilities
+
+service orchestration
+  -> DAO / stores / adapters / external clients
+```
+
+Keep a layer only for clearer ownership, isolated side effects, or direct business-rule tests.
+
+## Reuse and ownership
+
+Before adding a module, helper, service, or interface, find the concept owner and inspect callers.
+
+1. Reuse when the contract already matches.
+2. Extend for the same concept when the contract stays coherent.
+3. Keep local when reuse needs flags, broad optional inputs, unrelated modes, or leaky terms.
+4. Generalise only after stable common behaviour appears across real callers.
+
+Do not duplicate canonical rules or distort an abstraction to force reuse. Small local duplication can beat coupling unrelated concepts.
+
+## Server
+
+### Routers and controllers
+
+Routers declare paths and middleware. Controllers map validated HTTP input to typed service arguments, then results/errors to responses.
+
+Keep reusable calculations, domain decisions, transformations, persistence workflows, and integration coordination out of handlers. Simple reads may stay direct when a service would only pass through.
+
+### Services
+
+Services orchestrate use cases and side-effect boundaries. Make ordering and effects visible. Move substantial branching, calculation, comparison, parsing, and transformation to pure utilities.
+
+### Pure utilities
+
+Pass required state, config, and time explicitly. No I/O, stores/globals, logging, websocket publication, browser inspection, or caller-owned mutation unless explicitly contracted.
+
+Use focused Vitest coverage. Colocate feature logic. Move to `ontime-utils` only for genuine cross-package use.
+
+### State and boundaries
+
+- DAOs/data providers: persistence.
+- Stores: mutable runtime state.
+- Adapters/clients: external protocols and integrations.
+- Validators/parsers: protect boundaries before domain logic.
+- Commit state before dependent notifications or invalidations.
+
+Old layering exceptions are context, not precedent. Improve touched boundaries only through focused, behaviour-preserving moves.
+
+## Client
+
+- `common/api`: HTTP transport.
+- `common/hooks-query`: TanStack Query reads, mutations, keys, cache, invalidation.
+- `features`: reusable product capabilities and domain behaviour.
+- `views`: route-level composition.
+- `common`: genuinely cross-feature code.
+
+Keep substantial rules out of JSX, effects, and handlers. Use tested, colocated pure utilities. TanStack Query owns server state; established Zustand/context owns local state. No parallel caches.
+
+Limit subscriptions with selectors. Keep effect dependencies stable. Clean up listeners, intervals, external resources.
+
+## Shared packages
+
+- `ontime-types`: shared contracts; type-focused.
+- `ontime-utils`: environment-independent, side-effect-free shared logic.
+- Never import application layers into shared packages.
+- Keep feature-specific helpers with their owner, even when used by another file.
+
+## Review prompts
+
+- Business rule understandable/testable without app startup?
+- Transport, orchestration, state, transformation separated?
+- Existing owner reused without forcing unrelated behaviour?
+- Abstraction removes concepts rather than relocating them?
+- Smallest focused remedy clear?
