Gaps
The gaps index lists 22 notes for infrastructure already in the directory, in alphabetical order. Each note quotes what a primary page documents and what it does not document across settlement asset, spend controls, revocation, protocol composition, license, governance body, and cross-company use. Not documented is tied to the read date. The index does not rank listings.

How to read a cell
Documented means a cited page states the fact. Not documented means that page does not state the fact. Mixed means the note has both. Omitted means the note has no checked source for that dimension.
Not documented is not a claim that the fact is false. The read date stays on the claim. The table sort is a display order, not a score.

Questions
- What does not documented mean?
- Not documented means the cited page does not state the fact. The line names that page and the day it was read. It is not a claim that the fact is false.
- What does omitted mean?
- Omitted means this note has no checked source for that dimension. The dimension was left out rather than filled in.
- Does the index rank these products?
- No. The table can be sorted by name, by dimension status, or by checked date. Sort order is not a score.
- Where is the machine readable file?
- GET /data/gaps.json. The file includes every note, the cited sources, and the read dates.
