WORLD EVENT LITERACY
A local-only heuristic review of markers, labels, moving layers, timeline pace, dossier length, source visibility, keyboard access, reduced motion, and low-bandwidth parity.
ORIENTATION
Readers often compensate for a crowded interface until comprehension, context recovery, or accessibility suddenly fails. A visible pre-release pressure review can identify where clustering, progressive disclosure, static alternatives, and rollback testing are required.
LOCAL-ONLY HEURISTIC
The numeric bands below prioritize review. They do not diagnose cognitive load, certify accessibility, measure a person's ability, or replace representative testing with real tasks and access modes.
WORKING BRIEF
Record markers, text labels, moving layers, event pace, and dossier length at the same viewport and task. Hidden layers and progressive disclosure should be documented rather than assumed.
State whether source context, keyboard operation, reduced motion, and low-bandwidth alternatives are actually available. A promise to add them later does not satisfy the review.
The workbench aggregates design pressure to prioritize review. It does not measure intelligence, attention, disability, diagnosis, competence, or an individual user's capability.
Clustering, label prioritization, event staging, progressive disclosure, static alternatives, semantic tables, and explicit source panels are suggested when the related trigger is present.
Test comprehension, task success, errors, context recovery, workload, keyboard completion, screen-reader output, motion comfort, mobile use, and constrained bandwidth.
Do not ship a feature merely because it increases engagement. Confusion, source invisibility, loss of keyboard access, motion harm, or inaccessible fallback should trigger revision or rollback.
COMPLETE DOSSIER
Terms are defined for this site’s evidence method, not as universal legal or clinical definitions.
| Pressure source | Low-review prompt | Escalation prompt | Common response |
|---|---|---|---|
| Markers | Sparse and individually legible | Hundreds visible without clustering | Cluster, filter, aggregate, or stage |
| Labels | A small prioritized set | Persistent labels occlude evidence | Progressive disclosure and deterministic priority |
| Motion and layers | One bounded change at a time | Several moving layers compete | Pause, stage, simplify, and respect reduced motion |
| Timeline pace | Reader-controlled or event-staged | Changes arrive faster than they can be explained | Slow, pause, summarize, and show gaps |
| Dossier length | Scannable summary with clear headings | Long text competes with a dynamic view | Progressive disclosure and source-first structure |
| Access fallbacks | Keyboard, semantic table, static mode, low-bandwidth path | Any equivalent path is missing | Block release until parity is tested |
Can representative users locate, compare, explain uncertainty, trace a source, and recover context?
Pass condition: Task success and comprehension remain acceptable without extreme compensatory effort.
Can the same task be completed by keyboard, screen reader, reduced-motion, mobile, and constrained-bandwidth users?
Pass condition: No access mode loses the evidence, controls, or conclusion.
Are every numeric band and rule identified as a test fixture rather than a universal human limit?
Pass condition: The interface exposes the rule trace and links to empirical validation duties.
Are stop, revision, and rollback conditions specified before testing?
Pass condition: Source invisibility, context loss, inaccessible controls, or motion harm blocks or reverses release.
