BUILD FILE. 001 / SELF-DIAGNOSTIC

This site is also a system under test.

Aesthetics open the conversation. This dossier shows what lies underneath: rendering, budgets, degradation, security, and delivery contracts.

SYSTEM LENSES. 00 / PRODUCT → CODE

Three lenses. The same builder.

Product, systems architecture, and applied AI are angles on the same practice: turning a question into something that can be used and evaluated.

PRODUCT ENGINEERING / ACTIVE LENS

From hypothesis to real use.

Code starts with the problem, crosses a complete vertical slice, and returns as a product signal.

  • React
  • Next.js
  • React Native

DELIVERY TRACE. 01 / REQUEST → EVIDENCE

Content first. Interaction later.

The route delivers semantics and navigation before JavaScript. Motion and tools arrive as progressive enhancement through small boundaries.

  1. 01
    ROUTE

    Page contract

    Metadata, semantic content, and JSON-LD are born with the route and never depend on hydration.

  2. 02
    BUILD

    Static compilation

    Vinext and Vite resolve pages, styles, and modules before release; the sanitizer inspects the output.

  3. 03
    DELIVERY

    Versioned payload

    CSS, JavaScript, and fonts receive immutable names; responsive media keeps explicit dimensions and its own cache.

  4. 04
    ENHANCE

    Interaction attached later

    Seven small islands add movement and controls without taking ownership of the main content.

semantic route → sanitized build → immutable assets → bounded enhancement

PERFORMANCE BUDGET. 02 / BOUNDED COMPLEXITY

Every effect pays rent.

Values measured in the latest local artifact. Limits live in code and fail verification when a change exceeds the agreement.

CLIENT ISLANDS. 03 / WHAT HYDRATES — AND WHY

Seven modules. Seven exits.

Each island has a narrow responsibility and a path without JavaScript. The fallback is part of the design, not an error message.

Interactive modules, responsibility, and fallback without JavaScript.

ADAPTIVE UI. 04 / THE ENVIRONMENT IS ALSO INPUT

An aesthetic that knows when to recede.

System preferences change presentation and motion without requiring a separate menu. Information remains available in every mode.

continuous movement and decorative transitions stop
02update: slow
canvas and animations follow the same economical path as reduced motion
03prefers-reduced-transparency
surfaces receive opaque backgrounds and more explicit borders
04prefers-contrast: more
secondary text and separators receive additional contrast
05forced-colors: active
system colors replace effects that do not carry information

THREAT MODEL. 05 / SMALLEST USEFUL SURFACE

Trust does not come from the layout.

The portfolio needs no camera, cookies, or persistent tracking. Aggregate metrics use same-origin intake while the remaining policies stay closed.

  1. 01 / EXECUTION

    Closed origin, explicit bootstrap

    CSP keeps files on the same origin and blocks executable attributes; the runtime-required inline bootstrap remains a documented cost.

    POLICY / ENFORCED
  2. 02 / EMBEDDING

    A surface that cannot be framed

    Frame ancestors, frame source, and X-Frame-Options prevent silent third-party embedding.

    POLICY / ENFORCED
  3. 03 / CAPABILITIES

    Permissions denied by default

    Camera, microphone, geolocation, payments, USB, and browsing topics remain disabled.

    POLICY / ENFORCED
  4. 04 / PRIVACY

    Minimal, declared measurement

    Vercel Web Analytics measures aggregate page views and referrers through same-origin routes, without cookies, persistent identifiers, remote fonts, or advertising pixels.

DECISION LEDGER. 06 / CONTEXT → CHOICE → COST

A decision ends with a consequence.

Four short ADRs record why the implementation took this path, what was left out, and which evidence keeps each choice honest.

  1. ADR-001 / ACCEPTED

    Static route, explicit islands

    The portfolio needed to combine long-form narrative and interactive tools without turning every page into a client application.

    DECISION
    Pre-render content and metadata in Server Components; hydrate only seven modules with narrow responsibilities and named fallbacks.
    REJECTED ALTERNATIVE
    A single SPA would simplify global state, but reading, navigation, and indexing would depend on a larger client boundary.
    ACCEPTED CONSEQUENCE
    Composition requires contracts between HTML and islands, but content, links, and structure remain useful before JavaScript.
    STATIC HTML / 07 ISLANDS / NO-JS FALLBACKS
  2. ADR-002 / ACCEPTED

    Motion constrained by the environment

    Particles and transitions help communicate a technology lab, but they can compete with reading, battery, CPU, and visitor preferences.

    DECISION
    Use a deterministic 2D canvas with capped density and DPR, visibility and intersection pauses, and reduced modes driven by preferences.
    REJECTED ALTERNATIVE
    WebGL and a 3D scene would increase spectacle at a disproportionate cost for a layer that carries no essential information.
    ACCEPTED CONSEQUENCE
    The effect is intentionally less cinematic, but it recedes predictably and never changes hierarchy or navigation.
    BOUNDED CANVAS / DPR CAP / ADAPTIVE MOTION
  3. ADR-003 / ACCEPTED

    Native primitives before custom controls

    Dense cases must progressively reveal detail without hiding content from keyboards, assistive technology, or non-hydrated environments.

    DECISION
    Prioritize links, anchors, tables, meter, details, and summary; add client behavior only when the primitive cannot solve the task.
    REJECTED ALTERNATIVE
    Fully custom accordions and meters would offer more visual control but recreate focus, state, and semantics already available in the browser.
    ACCEPTED CONSEQUENCE
    Some nuances vary across browsers; in exchange, the basic path stays operable, recognizable, and easy to audit.
    NATIVE DISCLOSURE / SEMANTIC METER / KEYBOARD PATH
  4. ADR-004 / ACCEPTED

    Public inspection with aggregate measurement

    Recruiters, readers, and crawlers need to verify authorship, projects, and quality, while the lab also needs to understand its traffic reach and origins.

    DECISION
    Publish portfolio.json, RSS, sitemap, and humans.txt with tested contracts; use only Vercel Web Analytics, without cookies, through same-origin routes.
    REJECTED ALTERNATIVE
    GA4, advertising pixels, and persistent identification would offer deeper funnels but expand collection, network, consent, and privacy risk.
    ACCEPTED CONSEQUENCE
    Page views and referrers are measured in aggregate; there is no persistent profile, session replay, or individual visitor identification.
    PUBLIC CONTRACTS / COOKIE-FREE ANALYTICS / SAME-ORIGIN CSP

QUALITY PIPELINE. 07 / FAIL THE BUILD

Opinion in design. Contract in delivery.

Review runs from editorial data to the HTTP response. Each stage reduces a different class of surprise before a version is considered ready.

CONTRACT BOARD. 08 / LATEST CUT

Six gates. No vanity bar.

01 / TYPE SYSTEMPASS
STRICT

TypeScript as a contract

Strict types, exact optionals, and defensive indexed access block ambiguity before the build.

02 / STATIC ANALYSISPASS
0 WARN

Lint without amnesty

ESLint and JSX/ARIA rules fail on errors and warnings alike; accessibility is never postponed.

03 / CONTRASTPASS
84 AA

Measured readability

Audited information pairs pass WCAG AA, with dedicated adaptations for contrast and forced colors.

04 / PRIVACYPASS
1 ANALYTICS

Aggregate measurement

Vercel Web Analytics records aggregate page views without cookies, persistent profiles, remote fonts, or advertising pixels.

05 / INTERACTIONPASS
28.3 KB

Bounded complexity

Seven custom modules remain isolated and below the 29 KB budget; useful content arrives first.

06 / DISCOVERYPASS
28 URL

Findable and readable

Sitemap, JSON-LD, RSS, canonicals, and JSON Schema connect pages, cases, writing, authorship, and contract.

BUILD HISTORY. 09 / FOUR CUTS

The result preserves the path.

A short release log for the interface itself. Each cut added a verifiable capability without erasing the decision that came before it.

  1. CUT. 01

    The brand became an interface

    Palette, Sora, flask, and laboratory language became a responsive editorial composition.

    TOKENS / ICONS / STATIC ROUTES
  2. CUT. 02

    The manifesto became a system

    Home, Experiments, and Zero were separated; blog, sitemap, RSS, and structured data opened discovery.

    MULTI-PAGE / SEO / WRITING
  3. CUT. 03

    The showcase became evidence

    Cases gained maps, trade-offs, traces, failures, and questions for deeper technical evaluation.

    04 CASES / TRACES / QUESTIONS
  4. CUT. 04

    Evidence gained a contract

    Real budgets, incident drills, machine-readable surfaces, and the build itself became inspectable.
