I. Question architecture

An answering machine does not read a page; it looks for the shape of an answer. Most of what this archive knows is easiest to state truthfully in that shape, and the archive already held every one of those answers. It had no way to emit them as answers.

I.1

A page may emit a question node: FAQPage for more than one question, QAPage for exactly one. The archive emits whichever is true rather than always the larger of the two.

I.3

Every answer is composed only from fields the record carries. There is no generated prose. A question the record cannot answer does not ship — enforced by returning nothing rather than something.

I.4

Every answer carries its warrant: a citation naming the attestation, and isBasedOn pointing at the record's own provenance node.

I.5

The page and the graph say the same thing, in the same words, with the same citations.

I.6

At most eight questions to a page — a term of the archive's page-weight guard, not a matter of taste. Fewer than two answerable questions and no node is emitted at all.

I.7

The addendum declares itself separately. The ratified profile's own conformance declaration is unchanged.

II. The addressed holding

The ratified profile emitted a boundary by putting its coordinates inside the page. On the record of the Charles River Reservation that came to 940,481 bytes of one document — fourteen times the archive's own page-weight ceiling — and it put the record's identity behind a wall of numbers. Coordinates are data. Data in this archive is a preserved holding with an address, a media type, a licence, and a digest.

II.1

A page must not inline a coordinate array. The boundary is a Map node addressing a self-hosted geo+json holding, with its size, digest, and licence.

II.2

A page must not inline a column dictionary. The publisher's dictionary is a DataDownload addressing a self-hosted holding, preserved verbatim.

II.3

One shape across the corpus. Wide records and narrow ones emit the same nodes in the same positions.

II.4

A rendered map is an ImageObject carrying its alternative text in both caption and description. The schema refuses to store an image without it.

II.5

Every asset is rendered server-side, at accession, and never in a browser.

II.6

An asset is served with its digest and its licence in headers, so a consumer that never parses the graph still receives both.

II.7

The move is a recorded transform on each record it touched. It is not a silent edit.

II.8

What is simplified says so. The drawing is simplified for display; the GeoJSON holding is not.

III. What this addendum refuses

An invented question. A question whose answer would have to be composed rather than assembled is not emitted, however useful it would be to a search engine. The archive has no opinion it did not accession.

An unlabelled picture. The schema will not store an image asset without alternative text, so a page cannot emit one.

Borrowed conformance. Pages declare this addendum provisional for exactly as long as it is unsigned.

Deleting what it moves. Nothing an addressed holding contains was removed from the archive. The boundary, the dictionary, and the list of contained places are each served whole at a stable address, and the page that no longer inlines them names that address in the reader's own sentence.

Attestation

The signature block stands open in the instrument of record. On signature, one constant moves in the reference implementation and the whole emission surface advances in a single edit.
