/// Pins how DanaKit's emitted LoopKit Alerts are routed through Trio's alert
/// layer, as recorded by the synthesis audit over the managers / pump /
/// DanaKit sources (`DanaKit/Packets/DanaNotifyAlarm.swift`,
/// `DanaKit/PumpManager/PumpManagerAlert.swift`,
/// `DanaKit/PumpManager/DanaKitPumpManager.swift`).
///
/// What this suite pins:
///  - The CURRENT (not ideal) registry behavior for every alert DanaKit
///    issues. Unlike MinimedKit, DanaKit issues all 15 `PumpManagerAlert`
///    cases via `delegate.issueAlert` with managerIdentifier "Dana", which
///    MATCHES the registry key (AlertCatalogRegistry.swift:99-115). Every
///    emission therefore resolves to a registry `CatalogEntry` and is
///    overridden to that entry's interruptionLevel; the plugin itself sets no
///    interruptionLevel, so without a registry hit they would fall back to
///    LoopKit's default `.timeSensitive`.
///  - The documented escalation gaps, as a ratchet that fails when a gap is
///    fixed (forcing this file to be updated).
///
/// No classifier rows: every `DanaKitPumpManagerError` reaching
/// `APSManager.processError` is wrapped in LoopKit's `PumpManagerError` before
/// leaving the completion handler, so the exact `String(describing:)` input is
/// the wrapping, not the Dana case name. That input cannot be stated from the
/// synthesis audit alone, so classifier rows are omitted rather than guessed.
///
/// One-line gap summary: three taxonomy-Critical emissions are
/// under-escalated by the registry — `basalMax` and `dailyMax` (N2 Delivery
/// Suspended/Stopped -> `.critical`) are registered `.active`, and `unknown`
/// (N1 Hardware Fault catch-all -> `.critical`) is registered `.timeSensitive`
/// — so a daily/basal hard stop or an unrecognized pump alarm reaches the user
/// below critical.

///
/// IMPORTANT — what production actually feeds the classifier vs. what this
/// suite feeds: in prod, `categorize(error:)` falls through to
/// `categorize(pumpError:)`, which keys off `String(describing: error)` — i.e.
/// the Swift *case name* of the error value (e.g. "noConnection",
/// "failedTempBasalAdjustment"), NOT the human-readable display copy. This
/// suite instead catalogs every reportable DanaKit *message* (alert titles /
/// bodies, error descriptions, notification copy, onboarding/validation
/// strings) with its emission identifier, and pins how the ordered substring
/// classifier would route that exact natural-language text.
///
/// Why almost everything lands in `.other`: `categorize(pumpError:)`
/// lowercases the string and runs ordered `contains` checks for concatenated
/// tokens ("uncertaindelivery", "occlusion", "reservoirempty", "fault",
/// "timeout", "communication", "bolusfailed", ...). Natural prose rarely
/// contains those exact (space-free) tokens, so it falls through to
/// `.other(originalString)`. The only natural matches here are:
///   - the occlusion alert TITLE ("Occlusion" contains "occlusion") ->
///     `.occlusion`; its BODY ("Check the reservoir and infus...") does NOT,
///     so the body is a gap.
///   - connectivity strings that literally contain the word "timeout"
///     ("Connection timeout is hit...", "Timeout has been hit...",
///     "A bolus timeout is active...") -> `.commsTransient`.
/// Notably the reservoir-empty copy ("Reservoir is empty. Replace it now!" /
/// "Empty reservoir") does NOT contain "reservoirempty"/"emptyreservoir" (the
/// space breaks the token), so it falls to `.other` despite an N4 taxonomy.
///
/// Each `Row` pairs an emission identifier with its exact display string and
/// pins the category `categorize(error:)` returns for that string TODAY. The
/// pinned `expected` reflects the classifier's ACTUAL output on the verbatim
/// message (green by construction); see the per-row sourceRef comments, which
