PUBLIC DECISION MEMORY

How the service has evolved

This is more than a feature list. Each entry records why a change mattered, how far it was verified, and what MathVoyage still cannot honestly claim.

How to read the states

Public operational

Available in production

Human review pending

Broad contextual review remains

Effect pending

User impact is not yet proven

Effect observed

Explicit observation evidence exists

Infrastructure

Public content moved to a static-first architecture

Source-controlled reading surfaces such as the map, Atlas, mathematicians, and concepts now use versioned artifacts and static pages.

Public operationalEffect pending

What changed

  • Public content remains source-controlled and is frozen into validated JSON artifacts at release time.
  • Static pages respond from the CDN while manifest hashes and artifact-size limits are checked automatically.
  • Only user data whose source of truth is PostgreSQL, such as public notebooks and future contributions, stays on a dynamic path.

Why it matters

It keeps shared explorations fast and resilient by avoiding an application-server and database round trip for each public read.

What remains unproven

Post-release CPU, response-time, and search effects still require an observation window. Shipping the architecture is not proof of impact.

Experience

The home-map voyage now makes the next move predictable

After choosing a “Why here?” voyage, moving, closing, going back, and entering free exploration now preserve the same context.

Public operationalHuman review pendingEffect pending

What changed

  • Closing the voyage panel exposes clear next choices and a route back to the current scene.
  • Browser Back restores a meaningful voyage step instead of jumping to an unrelated year or map position.
  • Mobile event cards and map framing now respect safe areas for place labels and timeline controls.

Why it matters

The map is the main stage for following the movement of time, place, and ideas rather than a decorative background.

What remains unproven

Device-by-device human review and measured comprehension or return-exploration effects remain pending; automated checks do not replace lived use.

Search & discovery

Korean and English explorations now have distinct search URLs

English documents now live under `/en` while established Korean paths remain intact, with per-language canonical, hreflang, and sitemap links.

Public operationalEffect pending

What changed

  • Korean retains the established path while English uses `/en` as its canonical route.
  • Shared scene and query state survives a language-path switch.
  • Sitemaps and document metadata declare the ko, en, and x-default relationship.

Why it matters

It lets search engines and people distinguish language variants and reopen a shared link in the intended language.

What remains unproven

Google indexing and ranking are not guaranteed at deployment time; actual impressions and clicks still require longitudinal Search Console observation.

Content

The Spatial Atlas reached twenty-four voyages

With “How Life Makes Patterns,” the map now holds 24 voyages about when, where, and through which needs and tools mathematics moved.

Public operationalHuman review pending

What changed

  • Twenty-four voyages and 339 scenes connect 189 canonical places through time.
  • Twenty-one intersections let several voyages read one place through different eras and questions.
  • A four-step lab distinguishes plant spirals, reaction–diffusion, L-systems, and cellular automata as different generative models.

Why it matters

It reveals the shoulders of trade, translation, observation, institutions, and tools that disappear inside a lone-genius biography.

What remains unproven

Map lines do not prove a single transmission lineage or civilizational superiority. Scene-level evidence boundaries and comprehensive human review remain necessary.
