Fase 0 (inventário) + Fase 1 (a regra) da migração total de comentários em
prosa para docs/notes/. Este PR muda regra, não código.

Fase 0 — inventário, medido no origin/main de hoje

Contado por script, por área. // em prosa = linha // que não é ponteiro
Nota: nem diretiva de máquina. /** */ = linhas dentro de blocos doc
(contadas com parser que respeita */ na mesma linha; um falso positivo em
string literal — preview.test.ts:179, "/** Structured language…" — foi
excluído à mão).

área // prosa // ponteiro // diretiva /** */ linhas (arquivos) ///+//! // Rust
src/hooks/ 6 22 4 52 (15) — —
src/app/ 59 73 6 69 (9) — —
src/chrome/ 301 115 44 438 (48) — —
src/surfaces/ 379 201 39 823 (56) — —
src/lib/ 779 248 21 2905 (180) — —
src-tauri/src/ (41 arquivos) — — ~388 atributos 0 725 299
scripts/ (19 arquivos) 110 # — 11 shebangs — — —
total 1524 659 no src (684 com Rust) 114 TS 4287 (321 arquivos) 725 299

Notas de leitura, para ninguém recontar errado:

  • O número "322 arquivos com /** */" que circulou inclui o falso positivo
    acima. O real é 321 arquivos com bloco doc, 4287 linhas.
  • /* */ não-doc em src/: 13 linhas. Irrelevante em volume, migra junto.
  • Diretivas TS exatas: 114 @ts-/@vite-/@vitest-environment + 6
    eslint-disable. São código e ficam.
  • docs/notes/ hoje tem 825 âncoras
    (frontend 364, tauri-boundary 126, harness 121, sessions-tabs 99, state 71,
    settings 19, inbox 23, packaging 2).

Mapeamento área → notes e ordem dos PRs

# área notes volume de prosa aprox.
1 (piloto) src/hooks/ + src/app/ frontend.md, state.md 65 // + 121 doc
2 scripts/ novo scripts.md (comentários de release/build não têm área; enquadrar em packaging.md misturaria runtime com release) 110 #
3 src-tauri/src/ tauri-boundary.md (+ harness.md para harness.rs) 299 // + 725 ///
4 src/chrome/ frontend.md 301 // + 438 doc
5 src/surfaces/ frontend.md, sessions-tabs.md 379 // + 823 doc
6 (última) src/lib/ harness.md, state.md, settings.md, frontend.md 779 // + 2905 doc
7 (trava) guarda no CI estende scripts/notes-anchors.test.mjs —

src/lib/ é a última de propósito: 68% do volume doc mora nela
(locale.ts, opencode.ts, orchestration.ts), e é onde a taxa de
óbvio/duplicado/CORREÇÃO vai ser decidida caso a caso.

O que este PR faz

  • AGENTS.md: a regra parcial (que mantinha Rustdoc, /** */ de API e
    comentários de teste no lugar) vira a regra total.
  • RULES.md: bloco novo Code has no prose comments após Keep the fast paths fast, com o texto pedido.

O que este PR não faz

Nenhuma migração e nenhuma trava. A trava antes da migração quebraria o CI de
todo PR aberto; ela entra por último, contra código já zerado, como a tarefa
manda.

Verificação

Docs-only: node --test scripts/notes-anchors.test.mjs continua 3/3 (nenhum
ponteiro foi tocado).

Summary by CodeRabbit

  • Documentação
    • Atualizadas as diretrizes para proibir comentários em prosa no código. Justificativas de design devem ficar em docs/notes/, com âncora e fonte, e uma referência // Nota: no código.
    • As exceções permitidas incluem diretivas de máquina, shebangs e cabeçalhos de licença.
    • Esclarecido que a verificação confirma se cada referência aponta para uma âncora existente, mas não detecta comentários em prosa no código.

…nters

Replaces the partial migration rule (which kept Rustdoc, /** API blocks
and test comments in place) with the total one: prose comments of any
shape are forbidden in code, each migrates to a notes entry with anchor
and Fonte, and only machine directives, Nota pointers, shebangs and
license headers remain. RULES.md gains the binding block after Keep the
fast paths fast. Migration PRs per area and the guard test follow; this
PR changes no code.

# MonoCode Linux — Project Rules

## Code has no prose comments

Design rationale lives in `docs/notes/`, never in comments. New `//`,
`/* */`, `/** */` or `///` prose in any PR is a review failure. The rule is
enforced by review: `scripts/notes-anchors.test.mjs` only checks that every
pointer resolves to a real anchor, so it will not catch the prose for you.
Only machine directives, `// Nota: docs/notes/<area>.md#<anchor>` pointers,
shebangs and license headers may appear as comments.

Before / after behavior

  • observed — Modified behavior in AGENTS.md: A regra anterior permitia manter diretivas, Rustdoc, blocos de API e comentários de teste, e migrava apenas comentários explicativos. A nova regra proíbe comentários em prosa, exige migrar cada um para docs/notes/ com âncora e fonte, permite deixar somente a referência // Nota: e especifica as exceções: diretivas de máquina, shebangs e cabeçalhos de licença. Também declara que a revisão, não um teste, aplica a proibição, enquanto scripts/notes-anchors.test.mjs verifica se cada referência aponta para uma âncora real.
  • observed — Modified behavior in RULES.md: Adiciona a regra que direciona justificativas de design para docs/notes/, proíbe comentários em prosa e limita comentários permitidos a diretivas de máquina, referências // Nota: para âncoras válidas, shebangs e cabeçalhos de licença. Também declara que scripts/notes-anchors.test.mjs verifica referências a âncoras, mas não detecta prosa em comentários.

Comment thread AGENTS.md Outdated
CodeRabbit #287, and the finding is right. Both documents claimed
scripts/notes-anchors.test.mjs fails on new prose. It does not: walk()
reads src/**/*.ts{,x} that mention 'Nota: docs/notes', and the suite
asserts every pointer resolves to a real anchor. There is no prose
detection in it.

Both now say the rule is enforced by review, and name the test's actual
scope, so a future author does not assume the CI has their back.
