01.03 — KISS and ostentatious complexity#

The criticism that landed#

First public feedback Ocarina got, systematic per the author:

The first “criticisms” were often the same: “You’re bragging about something that’s very simple.”

The Holy Book takes its time answering. Three pillars: the operating nature of simplicity, the simple ≠ unsophisticated distinction, and the rejection of every “creative” counter-proposal that came in.

Simple ≠ unsophisticated#

This is also why KISS (Keep it simple, stupid) is so misunderstood in the industry. Many assume “simple” means “unsophisticated.” It would be hard to misread a principle more thoroughly.

What’s “simple” is the result of work. A terminal state, not a starting one.

The counter-proposals that got refused#

The “First feedbacks” chapter walks through, one by one, the contributions other “peers” tried to push. Every one quoted to be refused:

  • Twisting Ocarina’s ROP (Railway Oriented Programming) implementation until it lost all meaning, since they didn’t even know what ROP is,
  • Dropping “hooks” and other so-called “ninja techniques” right in the middle of test steps,
  • Abandoning typing,
  • Rewriting in Rust over “performance” concerns,
  • Forcing their clueless take on lazy evaluation and IoC down my throat like it’s gospel,
  • “Explaining” imperative vs. declarative programming to me while spewing complete nonsense,
  • “Talking” to me about event-driven programming, while still spouting nonsense,
  • And worst of all, pontificating about a horrifying theory of “declarative object-oriented programming,”
  • Etc.

Each refusal traces back to an Ocarina design choice:

RefusalOcarina choice
“Twisting ROP”Result[T], state machine ActionStart → ActionFailure → ActionSuccess → ActionChain, Neutral* for the failure rail. Strictly linear. Can’t be hijacked. See ../02-ocarina/03-railway/02-action-chain-states.md.
“Hooks in the middle of test steps”Hooks locked to create_act(on_failure=…, on_run_effect=…, act_counter_effect=…). No injectable global hook. See ../02-ocarina/03-railway/05-create-act-hooks.md.
“Abandoning typing”mypy strict = true, ruff select = ALL, PEP 695 generics everywhere, pytest-mypy-plugins to test the types. See ../04-internal-tests/04-mypy-plugins-types.md.
“Rewriting in Rust”Pure Python. The framework’s subject is readability and trade vocabulary, not raw performance — which doesn’t depend on the orchestration language here.
“IoC / lazy misunderstanding”Effect, Thunk, ChainRunner, validate(...).execute(), Watcher.callback — everything’s lazy, IoC documented in the code. See ../03-functional/.
“Declarative object-oriented”@final everywhere. No uncontrolled inheritance. Extension by composition (closures, project adapters).

The compliment being sought#

And if, upon reading a first test scenario, the reaction is “this is super simple…” it would be a shame to mean it as criticism: that is exactly the compliment being sought. Thank you.

That line is central. Simplicity of the result is the quality metric. The inverse — “look how sophisticated this is” — gets labeled narcissism in the Holy Book:

Narcissism expresses itself through making everything shamefully complicated for the sole purpose of domination. Not through acquiring skills and simplifying processes, since the end result is total malfunction: chaos.

Intolerance of failure, a narcissist tell#

The Holy Book names a clinical category: intolerance of failure as the narcissist’s signature in a testing environment.

They can also be recognized by their intolerance of failure. They systematically want to show how much THEY have “thought of everything.”

Never any red with a narcissist, only green, only “ready to ship to production.”

Ocarina goes the other way. A documented failure is worth more. Exactly the posture ocarina-with-ai-example holds, keeping its tests red on CURA’s gaps (see ../08-ai-example/05-security-gaps.md). From CURA_TEST_STRATEGY.md:

Any failure outside the intentional gap fails and the expected chrome BFcache reds listed above (plus the --workers 3 contention flake) is either a regression or a transient network error. Transient errors are auto-retried; persistent failures require investigation.

And the rule is engraved in the AI project’s CLAUDE.md:

Spec changes: update-frd-and-tests (FRD first, tests follow). Gap tests are reframed, not flipped.

Practicality as the goal#

The chapter’s closing line:

Instead of going nerdy, Ocarina focuses on solving small problems without creating bigger ones. The conclusion drawn from this is: “Ocarina is practical.” This is the purpose of Ocarina: its practicality.
