edui.inspector.presetActions

The Settings section's preset actions, offered on an asset's Settings section and on a component card's:

• Save as preset opens a name field beneath the section. Save captures the values the section shows as a typed preset targeting the declarer that governs them (preset.capture), and selects the new preset. A bare name lands in /source/presets; a path ending in .preset lands where it says. A name the capture refuses shows its reason beneath the section.
• Apply preset… lists the presets whose target is that declarer. Picking one applies it to the section's subject (preset.apply) as one undo step, and the outcome — the fields written, and any the target refuses — shows beneath the section.

local PresetActions = require("@builtin::editor.edui.inspector.presetActions")

local subject, declarer = PresetActions.subjectOf(ctx)     -- asset ref, or { entity, component }
for _, c in ipairs(PresetActions.presetsFor(declarer)) do  -- { ref, guid, name }
    print(c.name)
end
local outcome = PresetActions.applyInto(c.ref, c.name, { subject })  -- { text, tone }

SAVE and APPLY are the two entries settingsSection.ACTIONS carries. release(keyPrefix) forgets the open action, typed name, listed presets and outcome kept under a Context's key prefix; Inspector.release calls it.
