# Query Parameter Inventory

| Query param | Pages using it | Identifier type | Allowed? | Visible to user? | Clearable? | Persisted? | Conflicts | Notes |
|---|---|---|---|---|---|---|---|---|
| `tenant` | Finding Exceptions Queue, Customer Review Workspace, Governance Inbox, Baseline Compare, Baseline Profiles, Baseline Snapshots | slug/external id for most pages; sometimes accepted as database id | Conditional | Sometimes | Inconsistent | Sometimes converted into table/session filter | Conflicts with `managed_environment_id` naming and route tenant semantics | Browser: `tenant=<slug>` showed visible filter on Finding Exceptions and Customer Reviews; Customer Reviews clear did not remove URL and reload restored visible filter. |
| `tenant_id` | Legacy searches, compatibility code, tests | mixed | No for new context contract | Rarely | Unknown | Unknown | Conflicts with database key semantics | No high-risk browser route required `tenant_id`; keep as legacy cleanup target. |
| `managed_environment_id` | Operations, Provider Connections, Evidence Overview, Review Register, Decision Register, table filters | mixed: database id on Operations/Evidence/Reviews/Decision; slug/external id on Provider Connections | Conditional explicit filter only | Sometimes | Inconsistent | Yes through Livewire/Filament table filters on several pages | Same name carries different identifier types | Browser: Operations accepted DB id but showed "All environments"; Provider Connections accepted slug and filtered rows with no page-level clear. |
| `environment_id` | Search hits and compatibility code | unknown | No for new admin context contract | Not observed | Unknown | Unknown | Competes with `managed_environment_id` | Not observed in browser URLs during audited flows. |
| `tenant_scope` | Operations | enum/string (`all`) | Allowed for explicit all-environment view | Partly | Via Show all environments action | Query-backed | Interacts with `managed_environment_id` | Code sets `tenant_scope=all` when clearing operation environment context, but the environment CTA flow did not expose a direct `Clear filters` action. |
| `tableFilters` | Filament table state across list pages; route/query search hits | serialized Livewire/Filament state | Avoid for durable environment context | Usually hidden behind filter UI | Inconsistent | Yes | Can override sidebar intent after hydration | Code state contracts mark several `tableFilters` carriers as session-restorable and tenant-sensitive. |
| `activeTab` | Operations dashboard CTA | string enum | Allowed for operations lane | Visible as tabs | Via URL/tab navigation | Query-backed | Combines with `problemClass` and tenant filter | CTA used `activeTab=terminal_follow_up`. |
| `problemClass` | Operations dashboard CTA | string enum | Allowed for operations lane | Visible as tab/filters | Via URL/tab navigation | Query-backed | Can mask tenant filter impact | CTA used `problemClass=terminal_follow_up`. |
| `register_state` | Decision Register | string enum | Allowed for register lane | Visible as register tab/count | Link-based | Query-backed | Page access depends on current/filtered state | Workspace clean URL 403 for audited actor, but `managed_environment_id=4` opened the page. |

## Key Finding

The same logical environment prefilter is represented by at least `tenant`, `managed_environment_id`, `tenant_scope`, and hidden `tableFilters`. Identifier type also drifts: Provider Connections uses environment slug/external id under `managed_environment_id`, while Operations/Evidence/Reviews/Decision use database ids under the same param name.
