1	Parent Doc:	Design Doc: ES6 modules in Blink		Fields
2	Spec Algorithm	Blink Entrypoint	Blink Impl	module script	url	fetch client settings object	module map settings object	destination	cryptographic nonce	parser state	credentials mode	referrer	ancestor list	top-level module fetch flag	type	mode	source text	muted errors	module record	instantiation state	instantiation error

3	Fetch a module script graph	Mtor::fetchTree	ModulatorImpl	N/A	arg	arg		arg	arg	arg	arg	fill "client"	N/A	fill "top level fetch"	N/A	N/A	N/A	N/A	N/A	N/A	N/A
4	Fetch a module worker script graph	TODO	ModulatorImpl	N/A	arg	arg	arg	arg	fill "" (empty string)	fill "not parser inserted"	arg	fill "client"	N/A	fill "top level fetch"	N/A	N/A	N/A	N/A	N/A	N/A	N/A
5	Internal module script graph fetching	Mtor::fetchTreeInternal	ModuleTreeLinker	N/A	arg	arg	arg	arg	arg	arg	arg	arg	arg	arg	N/A	N/A	N/A	N/A	N/A	N/A	N/A
6	Fetch a single module script	Mtor::fetchSingle	ModuleMap	N/A	arg	arg	arg	arg	arg	arg	arg	arg	N/A	arg	N/A	N/A	N/A	N/A	N/A	N/A	N/A
7	^^ Steps 5-9 (new module script fetch)	Mtor::fetchNewSingle	ModuleScriptLoader	N/A	arg	arg	N/A	arg	arg	arg	arg	arg	N/A	N/A	fill "script"	fill "cors"	N/A	N/A	N/A	N/A	N/A
8	Perform a fetch	N/A	ScriptResource::fetch	N/A	arg	arg	N/A	arg	arg	arg	arg	arg	N/A	N/A	arg	arg	N/A	N/A	N/A	N/A	N/A
9	Fetch the descendants of a module script	N/A	MTLinker::fetchDescendants	arg	from MS	from MS	from MS	arg	from MS	from MS	from MS	from MS baseURL	arg	fill "Not top level fetch"	N/A	N/A	N/A	N/A	N/A	N/A	N/A
10												base url
11	Create a module script		MSLoader::createModuleScript	N/A	N/A	arg		N/A	arg	arg	arg	arg	N/A	N/A	N/A	N/A	N/A	N/A	N/A	fill "uninstantiated"	fill None

13	Spec Concepts: {Structure, Enum, Flag}		Blink Impl
14	"script"		TODO	N/A	N/A	has_a		N/A
15	"classic script"		PendingScript???	N/A	N/A	↑		N/A					N/A	N/A	N/A	N/A	has_a	has_a	N/A	N/A	N/A
16	"module script"		ModuleScript	N/A	N/A	↑		N/A	has_a	has_a	has_a	has_a	N/A	N/A	N/A	N/A	N/A	N/A	N/A	has_a	has_a
17	"module record"		ScriptModule	→	v8::Module
18	"environment settings object"		ScriptState		Note: ScriptState owns V8PerContextData which owns Modulator which owns ModuleMap
19	"module map settings object"		Modulator		Note: a module map settings object is an environment settings object in the spec (from domenic@)
20	"fetch client settings object"		ResourceFetcher Modulator::m_fetcher
21	"cryptographic nonce"		WTFString
22	"parser state"		ParserDisposition
23	"credentials mode"		WebURLRequest::FetchCredentialsMode
24	"instantiation state"		InstantiationState
25	"referrer" in fetch spec		{Atomic,}String
26	"referrer policy" in fetch spec		weborigin/ReferrerPolicy
27	the environment settings object's Realm		v8::Context

29	Blink Parameter Object
30	ModuleScriptFetchRequest				has_a			has_a	has_a	has_a	has_a	has_a
31
32			Legend	N/A	The value doesn't make sense for the algorithm.
33				arg	The algorithm takes the value from its caller for its argument
34				fill X	The algorithm fills in value X to use when invoking other algorithms
35				from MS	The algorithm extracts and use the value from its "module script" argument.
36				has_a	The spec structure + corresponding Blink class instance "has_a" value
37				Blink has_a	The corresponding Blink class instance "has_a" value, although the corresponding spec structure doesn't have the value.
38				↑	The parent "has_a" value
