Summary

Implements the second review of all briefs.

Structure and tooling

• The nav, README and index now group topics into Fundamentals, Languages, Web, Infrastructure and Domains, alphabetical within each group.
• New scripts/lint_briefs.py checks the AGENTS.md rules:
  • at most 6 bullets and 3 bold terms (outside tables) per concept;
  • at least 2 concepts per section;
  • no "as above" references;
  • no duplicate concepts or double blank lines;
  • every topic listed in README, index and nav.
• New check.yml workflow runs the lint and zensical build --clean --strict on pull requests. The Pages workflow also runs the lint.
• AGENTS.md documents the groups, the bold limit, the minimum section size and the lint script.

Content (concepts: 537 → 596)

• Ethereum restructured into smaller concepts:
  • New Solidity section: data locations, checked arithmetic, gas optimization patterns.
  • DeFi split into AMMs, lending and flash loans, MEV, and bridge exploits.
  • Transaction types moved into a table.
• Misfiled items moved:
  • Algorithms: new Strings and Greedy/backtracking sections.
  • System: geospatial indexes moved out of Sketches.
  • JavaScript: Memory separated from Metaprogramming.
  • Frontend: new CSS section; React split into rendering model and hooks pitfalls.
  • Security: attacks split into server-side and browser-side, plus a new Authorization section.
• Gaps filled:
  • AI: attention cost, mixture of experts, reasoning models, batch and streaming.
  • JavaScript: Node.js runtime (libuv thread pool, backpressure, workers, AsyncLocalStorage).
  • DevOps: persistent volumes, workload identity, CI practices.
  • System: long-lived connection balancing, cache and database consistency, proximity service, file sync, metrics aggregation, job scheduler.
  • Security: command injection, SSTI, XXE, prototype pollution, request smuggling, CSP, open redirect.
  • Rust: async locks; Deref, AsRef and Borrow.
  • Python: functools.cache pitfalls, dataclass default_factory.
  • TypeScript: 6.0 defaults, utility types on unions.
  • OS: cgroup memory limits, swap, NUMA.
  • Networking: TCP keepalive and half-open connections.
  • Backend: PATCH formats, health endpoints.
  • Go: PGO, GODEBUG.
• Cleanup:
  • Removed duplicates (Go version list, TypeScript satisfies, AWS SCP and ALB bullets) and generic advice.
  • Merged one-line concepts and single-concept sections.
  • Trimmed bold terms to at most 3 per concept.
• Facts re-checked: Lambda Managed Instances 90-minute timeout (Sept 2026); Temporal (Stage 4, ES2026; Safari only in Technology Preview).

Test plan

• python scripts/lint_briefs.py: 0 problems
• zensical build --clean --strict: no issues
