Master artwork (vector source)
The controlled vector source the logo really lives in. Every PNG, favicon, and t-shirt print is exported from it, never redrawn.

What it is
The canonical source artwork the logo actually lives in: a controlled vector file, or a small controlled set of them, usually .ai, .svg, or .eps. In practice it is a set more often than a single file, because one brand normally needs an RGB master and a CMYK or spot-color master, plus the approved variants (full color, one color, reversed). What makes it master artwork is not the file count, it is that everything downstream is exported from it. Every PNG, favicon, embroidery file, and vinyl cut comes out of it. Nothing downstream gets redrawn, and nothing gets traced back up from a raster.
A real master has live paths (not an autotraced blob), type converted to outlines so it survives on a machine without your font, no stray hidden layers or live effects, and an artboard trimmed to the mark's true bounding box so alignment is predictable. Ask for it by name at delivery: 'master artwork, vector, outlined' beats 'send me the logo', which gets you a 600px PNG with a white box behind it.
Gotchas: keep a second copy with live text for future edits, because outlined type cannot be re-kerned. And keep separate RGB/hex and CMYK/Pantone masters instead of converting at export time, since automatic color conversion is where brand color quietly drifts between screen and press.
Ask AI for it
In a vector-capable editor, clean the attached approved source vector using the supplied font and color specifications [FONTS] and [COLOR VALUES]. Preserve the approved geometry exactly: remove stray anchor points, hidden layers, and live effects, and trim the artboard to the mark's true bounding box, but do not redraw curves. Retain one source layer with live text for future kerning, and create an outlined production copy alongside it. Export the listed files: layered source, optimized SVG, 4000px transparent PNG, an RGB master, a CMYK master, and a spot-color master, each in full color, all-black, all-white, and one-color versions. Do not infer missing colors, Pantone equivalents, or typefaces: list anything not supplied as missing.
