Chapter 3 of 7 · Section 12 of 51

Sections

1. Intro

  • 1. Agenda
  • 2. Las Vegas, 2011 — where I learned to program

2. The Rails Lesson

  • 3. Convention over configuration
  • 4. The database was a shared design
  • 5. Controllers — where a request becomes a decision
  • 6. Parameter handling — the shape of what comes in
  • 7. Middleware — the layer I didn't know I needed
  • 8. "It works on my machine"
  • 9. How new all of this still was
  • 10. From Rails conventions to Navigator

3. Shared craft compounds

  • 12. Keep domain seams in Rust, where interest compounds
  • 13. Widely available — governed in the open
  • 14. A cautionary tale — Java, Oracle, and the price of a single owner
  • 15. Say it with your whole chest

4. Six ways to know a change holds

  • 16. One giant change deserves more than one glance
  • 17. The compiler asks whether the program can be true
  • 18. Clippy and rustfmt ask whether the code speaks our dialect
  • 19. Tests ask whether the promise still holds at the boundary
  • 20. Bloom turns verification into a learning loop
  • 21. Marketing copy must explain the way, not only the claim
  • 22. Three workshops, three people, one method
  • 23. Fast generation, slow enough verification

5. From Law to Workflow

  • 24. The goal — deterministic workflows from law
  • 25. Step 1 — read the law
  • 26. Step 2 — write the behavior before the code
  • 27. "It works on my machine" — so we stopped trusting my machine
  • 28. Step 3 — the template: a questionnaire and a workflow
  • 29. Step 4 — the attorney gate is a graph invariant
  • 30. Step 5 — signature is a modular step
  • 31. Step 6 — the filing, run durably
  • 32. "It works on my machine" — even when my machine dies
  • 33. Why a workflow beats a prompt
  • 34. Privacy-preserving operations are part of the product

  • 36. From Postgres to Rust — with a bridge
  • 37. The runtime story: keep the seam, change the engine
  • 38. One deployment bucket; many matter repositories
  • 39. Rust where we can own the path; partners at the edge
  • 40. Rust reaches the places lawyers work
  • 41. I want a commercial relationship with everything I depend on
  • 42. Always the latest, always Rust
  • 43. Swap the seam — it still works

  • 45. Ethics is part of the stack
  • 46. The simplest developer environment I can get away with
  • 47. The online developer environment
  • 48. "It works on my machine in the cloud — and on yours, and on my client's"
  • 49. Where we are today — live by August 19
  • 50. Betting on ourselves — Rust in peace

7. Wrap Up

  • 51. Take the method home

Keep domain seams in Rust, where interest compounds

The bet is not "write a service in Rust." Rust owns reusable domain systems: libraries, command-line tools, workers, editor integrations, tests, and — through Dioxus — the browser pages. The payoff is that each good decision reinforces the next one.

Presenter notes

The core claim for a Rust room is stronger than "Rust is pleasant" or "Rust is safe." The claim is that keeping domain seams in Rust changes the economics of a small team. A CLI can call the same validators as the website. A workflow worker can share the same state-machine types as the template authoring rules. The LSP can surface those rules in whatever editor a lawyer writes in. A release can ship one dated set of binaries, images, and editor assets. The ecosystem compounds when the domain seams stay in the same language long enough to reuse them.

That is why Rust owns Navigator's rules, workflows, storage, authorization, store, CLI, and — through Dioxus — the browser surface. navigator orchestrates machine-bound flows; there are no shell scripts and no Makefile. We do not win because we wrote more code than everyone else. We win when the code someone else wrote in the Rust ecosystem becomes a trustworthy brick in our law practice.
