Gaps

1. <Draft /> component mid-section — line 272 (explicit marker)

Original text:

<Draft />

Finding:
Placed in the middle of the "Parallel Documents" section, between "We have developed some slightly less nauseasting solutions to this problem." and the paragraph beginning "Tabs and slide-over windows..." — signals content is missing at that point.

Sources:

• Structural marker only; no external research applicable.

---

2. Pattern 3: Transpointing Windows — stubs — lines 293–295 (explicit marker)

Original text:

Parts of documents visibly point to other parts

LiquidText

Finding:
LiquidText is a PDF/document annotation app by LiquidText, Inc. (founded 2012; iPad, macOS, Windows). Its "pinch-to-compare" feature lets users collapse a document to show two sections side-by-side with live connection lines back to their source locations — the closest mainstream commercial implementation of transpointing windows. Named Apple's most innovative iPad app of 2015; Microsoft top productivity app of 2022. Added real-time collaboration in 2025.

3. Pattern 4: Transclusion — no body content — line 312 (explicit marker)

Original text:

- [[Transclusion and Transcopyright Dreams]]

Finding:
Section body is entirely absent; only an internal wiki link exists. No external research surfaced beyond Maggie's own note on transclusion.

Sources:

• N/A

---

4. Pattern 5: Bi-Directional Links — no body content — line 316 (explicit marker)

Original text:

- [[A Short History of Bi-Directional Links]]

Finding:
Section body is entirely absent; only an internal wiki link exists.

Sources:

• N/A

5. Version control date "1975" — lines 322–323 (soft signal)

Original text:

The first version control system dates back to [1975]((en.wikipedia.org/redacted) It's now difficult to imagine programming without it.

Finding:
The date is wrong. SCCS (Source Code Control System) — widely considered the first deliberate version control system — was started in 1972 by Marc Rochkind at Bell Labs. The 1975 date refers to the SCCS user manual publication (December 4, 1975). The first publicly released version (SCCS version 4) was February 18, 1977.

6. Pattern 7: Modular Text Blocks — stubs — lines 343–347 (explicit marker)

Original text:

Blocks construct documents

Notion pioneered this in the note-taking space

Explosion of note-taking apps using a block-first approach: Roam, Innos, Clover, Craft, Kosmik

Finding:
Notion v1.0 launched March 2016 (Product Hunt #1 Product of Day/Week/Month), introducing its trademark block model. The company was founded in 2013 by Ivan Zhao and Simon Last. Prior mainstream note apps used document (Evernote, 2008) or list (Workflowy, 2010) models rather than blocks-as-primary-unit. The "Notion pioneered" claim is defensible for the mainstream space.

7. Pattern 8: Stable, Universal Addresses — stubs — lines 349–357 (explicit marker)

Original text:

The web enforces addresess on the document level rather than the block level

No stability at all, link rot everywhere

URL queries and subpaths

Roam block UIDs

Finding:
Section is entirely stub notes. Note: "addresess" is a typo for "addresses." No additional external research surfaced.

Sources:

• N/A

8. Empty Hypothesis URL — line 361 (explicit marker)

Original text:

[Hypothesis]()

Finding:
Correct URL: **(web.hypothes.is/redacted) (also rendered as hypothes.is). Hypothesis is an open-source web annotation platform; in August 2022 it restructured from non-profit to a public benefit corporation ("Annotation Unlimited, PBC") to allow investment.

9. Pattern 10: "ZigZag format" — line 373 (explicit marker)

Original text:

ZigZag format

Finding:
ZigZag (also written ZZstructure) is a separate Ted Nelson invention — a multi-dimensional, cell-based data paradigm he calls "hyperthogonal," distinct from Xanadu's hypertext. Nelson's description: "everything is a cell and connections between cells." First Perl prototype by Andrew Pam, 1997; free software project GZigZag ran 2000–2003. U.S. patent 6,262,736 expired May 5, 2019. Nelson retains the ZigZag® trademark.

10. Pattern 11: "Jarons Lanier" name typo — line 377 (explicit marker)

Original text:

Jarons Lanier's dreams in Who Owns the Future

Finding:
Name misspelled. Correct: Jaron Lanier. Book: Who Owns the Future? (Simon & Schuster, 2013). Lanier proposes a universal micropayment system where users are compensated for data their activity generates; he explicitly cites Ted Nelson's two-way linking as a model for never-expiring micropayments.

11. Pattern 11: Coil stale reference — line 381 (explicit marker)

Original text:

Web Monetisation API, Coil

Grant for the Web

Finding:
Coil shut down in March 2023 (memberships cancelled February 10, 2023; creator payments ended March 15, 2023). The Web Monetization standard is now stewarded by the Interledger Foundation, which published a new W3C draft spec in September 2023. "Grant for the Web" (line 383) was originally a $100M fund launched in 2019, co-funded by Coil, Mozilla, and Creative Commons; it is now also run by the Interledger Foundation and remains active as of 2025 (awarded $200K in grants that year).
