/// Pins Trio's alert-routing behavior for the **TandemKit** pump plugin.

/// Rows are derived from the synthesis audit of the Tandem stack
/// (`TandemCore` / `TandemKit` / `TandemKitUI` / `TandemKitPlugin`; pump:
/// Tandem t:slim X2 / Mobi). The audit's central finding is STRUCTURAL:
/// TandemKit issues **zero** LoopKit Alerts. There is no
/// `issueAlert` / `retractAlert` / `Alert(identifier:)` / `DeviceAlert` /
/// `UNUserNotificationCenter` usage anywhere in the shipping targets
/// (audit.md:7-8, Notes:192), so TandemKit never constructs an
/// `Alert.Identifier` and there is no `(managerIdentifier, alertIdentifier)`
/// pair for Trio to route. The PRIMARY emitted-alert table is therefore empty
/// and `AlertCatalogRegistry` has — and could match — no Tandem entries.
///
/// Every Tandem pump alarm the device surfaces (occlusion N1->Critical;
/// empty/removed cartridge & "No Insulin" N4->Critical; battery-shutdown
/// N5-pump->Critical; temperature/altitude/stuck-button/invalid-date/
/// pump-reset & the non-dismissable Malfunction item N1->Critical;
/// resume-pump / auto-off delivery-stopped N2->Critical; CGM-alert catalog
/// N7->High) is rendered ONLY inside TandemKit's own in-app
/// "Pump notifications" settings list
/// (`NotificationBundle` -> `TandemKitNotificationsView`), which Trio never
/// receives. The `AlertResponseType` description catalog is intercepted in
/// `fetchNotifications` (audit:129,193) and is dead for display, and the lone
/// `didError` call site (`TandemPumpManager.swift:218`) has no callers.
///
/// GAP SUMMARY: the effective interruption level of every taxonomy-Critical
/// Tandem alarm is "never delivered" — strictly less severe than `.critical`.
/// This is broader than a registry-key mismatch: no `Alert.Identifier` is
/// ever issued, so no escalation is possible until upstream TandemKit issues
/// LoopKit Alerts (and adopts `AlertCatalogVendor`, or Trio adds Tandem
/// registry entries). The remediation gap is documented in this suite's prose
/// rather than as table rows, because there are no emitted-alert rows to ratchet.
///
/// The only Tandem signals that DO reach Trio are `PumpManagerError`-wrapped
/// `PumpCommError` / `TandemPumpManagerValidationError` values returned through
/// `PumpManager` dosing/limit/time completion handlers (e.g. `enactTempBasal`
/// -> `APSManager:703` `APSError.pumpError(error)` -> `processError` ->
/// `TrioAlertClassifier.categorize`). These are error-STRING emissions, not
/// Alerts. No classifier rows are pinned here: the TandemKit submodule is not
/// present in Trio-dev and the audit recorded the rendered `errorDescription`
/// text rather than the `String(describing:)` form, so the exact classifier
/// input (a LoopKit `PumpManagerError` enum — not `CustomStringConvertible` —
/// wrapping a `PumpCommError`/validation case) cannot be stated with
/// certainty. Per the SCOPE rule those are omitted rather than guessed.

///
/// IMPORTANT — what production actually feeds the classifier vs. what this
/// suite feeds it: in production `APSManager` hands
/// `TrioAlertClassifier.categorize(error:)` a LoopKit `PumpManagerError`
/// wrapping a `PumpCommError` / `TandemPumpManagerValidationError`, and the
/// classifier runs `String(describing:)` over THAT — i.e. it sees the Swift
/// **case name** (e.g. `pumpError(...)` / `pumpNotConnected`), not the rendered
/// display string. TandemKit also uses NONE of the LoopKit Alert / AlertIssuer
/// machinery and never delivers a live `pumpManager(_:didError:)`, so there are
/// no real LoopKit `Alert.alertIdentifier` values to attach (that structural
/// finding is pinned by the registry-routing suite above). Every user-facing
/// row here surfaces instead through one of: (1) `PumpCommError` /
/// `TandemPumpManagerValidationError` wrapped in `PumpManagerError` returned to
/// Loop completion handlers, (2) the in-app "Pump notifications" settings list
/// (`NotificationBundle` items whose displayed string is the formatted enum
/// case-name title), (3) `pumpStatusHighlight` strings, (4) SwiftUI
/// `.alert`/ActionSheet/ErrorSheet text, and (5) CGM settings status rows. The
/// `alertIdentifier` column is therefore the error enum case name / source
/// symbol for the row, NOT a LoopKit alert id.
///
/// This catalog deliberately feeds the classifier the **display string** of
/// each emission so we pin how the substring matcher handles real
/// natural-language text — the worst case for a token matcher. The classifier's
/// `categorize(pumpError:)` tokens are concatenated and space-free
/// ("notconnected", "noresponse", "reservoirempty", "sensorfailed", ...), while
/// TandemKit's prose has spaces, so almost every emission falls through to
/// `.other`. Only strings literally containing "occlusion"/"occluded" hit a real
/// bucket. Connectivity strings ("Pump not connected", "No response from pump",
/// "Pump Disconnected") do NOT match "notconnected"/"noresponse" because of the
/// spaces and wrongly land in `.other` — the principal gaps. See
/// `Trio/Sources/Services/Alerts/TrioAlertCategory.swift`.
