Checking this entry found 3 errors, now corrected: against its sources, or where it contradicted itself or its arithmetic did not hold. Each is listed here so a reader can see what changed. How references were checked.

2026-09-28 · Factual correction. Said the walkthrough is standardly run by two to four evaluators working independently and merging lists, which is heuristic evaluation's protocol; it now says a single analyst or a small panel working through the task together.
2026-09-28 · Factual correction. Summarised Norman's action cycle in four steps, contradicting the entry's own seven-part account; it now lists all seven.
2026-09-28 · Factual correction. Called the walkthrough's four questions Norman's; they come from the method's own literature (Wharton and colleagues), and Norman supplied the action cycle they build on.

Editions¶

Version	Date	Change	What changed
v3	2026-09-28	First citations: 5 claims in this entry now cite 5 sources, each footnote saying what that source supports; 1 claim is marked citation pending. 15 passages corrected against the sources that establish them, with independent review. The explanation of a parent relation was corrected.	prose — detailed body (prose edited) · structure — DAG parents (parent links changed)
v2	2026-09-19	Both layers now take their origin domain from one shared 65-domain roster. The domain-specific layer had drifted to 2,744 free-text domain labels, most used once and many just restating the entry's own subdomain, sharing only 18 of them with the closed list the primes used — so the same domain name meant different things in the two layers and their counts could not be read together. All 2,716 off-roster labels were mapped onto the roster, and the finer specialty each entry was authored with was kept as its subdomain, now a list rather than a single value; subdomains that only repeated the domain under an older or broader name were dropped. The prime side no longer reads a hand-maintained registry that had fallen behind the corpus — the Mathematics page listed 66 primes when 154 claimed the domain — and the 61 primes carrying no origin domain at all were classified. Every domain also rolls up into one of eight groups, shown on each entry and browsable in its own right.	structure — origin (fields changed)

Editions are cut at publish time from a content hash of the entity's canonical source, so a version changes only when the content actually changed. Full canonical content for every edition, and the exact per-part diffs between them, are in the downloadable editions archive (editions_archive.jsonl); the current-state index is versions.jsonl.
