review: comprehensive audit of architecture, CI/CD, and UI changes

[ashllll]

Problem Statement

Three groups of changes were made in rapid succession across architecture, CI/CD, and frontend design. A comprehensive review is needed to confirm correctness, standards compliance, and absence of architectural defects before these changes are considered production-ready.

Review Scope

Group A: Architecture Deepening

• Commits: 008c246, ee7d842, fa855b7
• Spec: GitHub Issue refactor: deepen architecture — timestamp parsing, config models, extraction policy #93
• Changes: unified timestamp parsing, split config models, extracted extraction policy hook

Group B: CI/CD Pipeline Hardening

• Commit: ecb11b3
• Changes: SHA-tag-based release, CI Gate, 6-platform matrix, documentation separation, checksums

Group C: Apple Glass UI Design System

• Commits: 75124bc, 006de7e
• Changes: glass CSS variables, glass component classes, full surface application

Review Axes

Axis 1: Standards Compliance

• AGENTS.md coding conventions
• ADR-0001 seam discipline (no hypothetical seams)
• Fowler smell baseline (Mysterious Name, Duplicated Code, Feature Envy, Data Clumps, Primitive Obsession, Repeated Switches, Shotgun Surgery, Divergent Change, Speculative Generality, Message Chains, Middle Man, Refused Bequest)
• Existing code style (Rust formatting, TypeScript conventions, Tailwind patterns)
• Tooling-enforced rules excluded (cargo fmt, clippy, tsc, eslint)

Axis 2: Spec Compliance

• Group A: Issue refactor: deepen architecture — timestamp parsing, config models, extraction policy #93 acceptance criteria (17 user stories)
• Group B: Implicit spec from grilling decisions (SHA consistency, CI Gate, Pages separation)
• Group C: HTML design demo (no gradients, white/dark modes, glassmorphism, all pages)

Axis 3: Architectural Design Defects

• Module depth: are interfaces small relative to implementation?
• Seam discipline: are seams real (2+ adapters) or hypothetical (1 adapter)?
• Dependency direction: does la-core remain dependency-free?
• Locality: do changes concentrate knowledge or scatter it?
• Leverage: do new interfaces serve multiple callers?
• Coupling: do changes introduce hidden dependencies?
• Naming: do new names match CONTEXT.md vocabulary?
• Reversibility: are changes easy to undo if wrong?

Test Seams

Group A seams

• la-core::TimestampParser::parse_unix_timestamp — timestamp parsing behavior
• la-core::models::config re-exports — backward compatibility after split
• useExtractionPolicy hook — frontend policy logic extraction

Group B seams

• scripts/check_ci_workflows.mjs --verify-remote — structural invariant validation
• scripts/validate-ci.sh — full CI pipeline
• GitHub Actions workflow syntax — actionlint

Group C seams

• npm run type-check — TypeScript compilation
• npm run test:ci — 441 frontend tests
• npm run build — Vite production build
• CSS variable definitions in index.css — light/dark theme tokens

Acceptance Criteria

• No confirmed Standards violations
• No confirmed Spec violations
• No architectural design defects identified
• Full CI (12/12) passes
• All 441 frontend tests pass
• All 530+ Rust tests pass
• TypeScript compiles cleanly
• Vite build succeeds

Out of Scope

• Reviewing code that was not changed in this session
• Proposing new architecture candidates
• Modifying any code (review only)
• Re-litigating rejected candidates from Issue refactor: deepen architecture — timestamp parsing, config models, extraction policy #93
