	// a cadence is the server's tick loop (ON by default on a schedule-capable store,
	// ADR 0073 — `mecated --no-scheduler` opts out).
	Sched client.ScheduleLister
	// Sessions is the stored-session inventory surface for the /sessions picker
	// (issue #245 Phase 2); nil disables it (the overlay is honestly absent). It is
	// the lister the picker calls to enumerate stored sessions. Unlike the
	// caps-gated overlays it is NOT gated on a ServerCapabilities bit — the picker
	// is available whenever a lister + authoritative transcript loader are wired
	// (a no-FS/cloud server with a durable SessionStore still has stored sessions).

	// taken from its source-correlated preflight, never inferred from row IDs.
	Adoption client.SessionAdopter
	// Transcript is the authoritative snapshot-derived conversation surface used

	Replayer client.SessionReplayer
	// LiveStream is the LIVE per-session event feed (ADR 0075 Scenario 5): the server
	// pushes fire-result delivery notes for the active session as they occur. The ui
	// holds the interface (not a *Client) so it is injectable with a fake for offline
	// tests. nil disables the live bridge (the ui still renders deliveries via the
	// replay on a session switch/reload, just not live). *Client satisfies it.

	// InitialModel is the persisted selection loaded at launch (composition-side,

	// marker) and the startup CreateSession carries it — AFTER the connect-time
	// ListModels reconcile clears it if its PROVIDER is no longer available. The
	// reconcile is provider-level only (issue #41): a model absent from the (possibly
	// embedded-floor) snapshot is still carried verbatim — the server validates it,
	// and a rejection falls back to the default loudly (connectFallbackMsg).
	InitialModel client.ModelSelection
	// WorkspaceDefault / GlobalDefault are the SEPARATE raw state-file values loaded at
	// launch (composition-side): the per-workspace entry (zero when none — see
	// WorkspaceDefaultSet) and the global `default:` block. They are display-only
	// provenance inputs for the /models picker's "current: <model> (<provenance>)"
	// line and the ★ global-default row marker — the ui derives a best-effort label

	// InitialPrompt is a CLI-supplied seed prompt auto-submitted once the first

	// NoBanner suppresses the rich first-run welcome splash (mascot + gradient

	// Set true by the --no-alt-screen/--inline flag — a first-class user opt-out
	// for streaming the session into native scrollback (so it stays
	// searchable/scrollable after exit) — and by golden tests so the final frame
	// persists in the captured output instead of being cleared on exit.
	NoAltScreen bool

	// NoMouse disables mouse capture on the alt screen (View leaves MouseMode at
	// MouseModeNone), so the terminal's OWN click-drag selection works again — at
	// the cost of in-app mouse-wheel scroll and the in-app drag-select/copy layer
	// (selectable() returns false). Keyboard scroll is unaffected. Default false
	// (mouse captured). Set true by --no-mouse / MECATUI_NO_MOUSE=1. Inert under
	// NoAltScreen (mouse is already off inline). The escape hatch for terminals
	// that strip OSC52 or users who prefer native selection.
	NoMouse bool

	// NoWindowTitle suppresses the dynamic terminal window/tab title, leaving the
	// title at the bare "mecatui" (no phase word, no session title). Default
	// false (the title is dynamic: "<title> — <status word> mecatui"). Set true by
	// --terminal-title=off / MECATUI_NO_TERMINAL_TITLE=1 — the escape hatch for
	// terminals/multiplexers where a set title does more harm than good (or where
	// the per-phase churn is unwanted).

	// DebugMouse turns on a footer diagnostic overlay (env MECATUI_DEBUG_MOUSE=1):

	// selection/coordinate issues (it is what surfaced the highlight-on-wrong-line
	// bug). Default OFF (zero cost when unset); main.go reads the env var.
	DebugMouse bool

	// DebugSteer turns on a steer correlation trace in the status line (env
	// MECATUI_DEBUG_STEER=1): each steer ack/echo logs the incoming message_id,
	// the live bundle's id, and the match/burn/drop decision, so a stuck or
	// mis-correlated steer lifecycle is visible in the TUI rather than opaque.
	// Default OFF (zero cost when unset); main.go reads the env var.
	DebugSteer bool

	// DebugAsk registers the /debug-ask built-in (env MECATUI_DEBUG_ASK=1): it
	// injects a fake permission ask with long Bash args through the REAL ask
	// reducer, so the modal's wrap/scroll/full-screen-args behaviour (issue #488)
	// can be exercised by hand without driving a live run. Default OFF (the
