+# ADR-081: Per-process output TMP dirs in draw-image test beforeAll
+
+## Статус
+Accepted (2026-07-31)
+
+## Контекст
+Тестовые файлы draw-image использовали общий output-каталог на тест-файл (`/tmp/draw-image-<name>`), создаваемый/очищаемый в `beforeAll`. При параллельном запуске нескольких процессов vitest concurrently (внешняя параллель, не intra-pool) процессы с одинаковым набором тест-файлов конкурировали за один каталог: `rmSync(TMP, recursive)` процесса A удалял PNG + `meta.json`, только что написанные процессом B → падение assertions (`existsSync`, `skipped vs rendered`, `unable to open for write`). Аналогично race на `input.svg` (#177, test helper), но для output-каталогов `beforeAll`. Issue #183.
+
+## Решение
+Уникализировать output-каталог на процесс через `process.pid` suffix: `TMP = path.join(os.tmpdir(), \`draw-image-<name>-\${process.pid}\`)`. Добавить `afterAll` cleanup где отсутствовал. `process.pid` уникален на каждый параллельный vitest-процесс → каталоги не коллизируют. Не использован `mkdtempSync` — детерминированный suffixed path проще для assertions и достаточно уникален для внешней параллельности (intra-pool workers у vitest по умолчанию forks → разные PID).
+
+## Альтернативы
+- `fs.mkdtempSync(path.join(os.tmpdir(), "draw-image-<name>-"))` — гарантированная уникальность даже при одинаковом PID (threads pool), но nondeterministic path усложняет дебаг. PID-suffix достаточен для текущего pool-режима vitest.
+- Vitest `--no-parallel` / `--pool=threads --poolOptions.threads.singleThread: true` — подавляет параллель, но не устраняет root cause и замедляет CI.

+pr: 186
+title: fix(draw-image): per-process output TMP in beforeAll for parallel vitest
+---
+
+## Что сделано
+- 7 affected тест-файлов `.opencode/draw-image/tests/` переведены с общего output-каталога `/tmp/draw-image-<name>` на per-process: `TMP = path.join(os.tmpdir(), \`draw-image-<name>-\${process.pid}\`)`.
+- Файлы: `render.integration.test.ts`, `render.optional.integration.test.ts`, `e2e.optional.test.ts`, `e2e.bad-input.test.ts`, `e2e.no-icon.test.ts`, `cleanup.test.ts`, `idempotency.test.ts`.
+- Добавлен `import os from "node:os"` где отсутствовал (5 файлов).
+- Добавлен `afterAll` с `rmSync(TMP, { recursive, force })` в 6 файлах (в `cleanup.test.ts` уже был — оставлен as-is).
+- Импорт `afterAll` добавлен в vitest-импорты 6 файлов.
+
+## Почему
+При параллельном запуске 10× `npx vitest run` процессы с одинаковым набором тест-файлов конкурировали за один output-каталог: `beforeAll` процесса A удалял `TMP` (вместе с PNG + `meta.json`, только что написанными процессом B) → assertion `existsSync(outPath)` падал с `expected false to be true`, idempotency-тест падал с `expected 'skipped' to be 'rendered'`, cleanup-тест — с `unable to open for write`. `process.pid` уникален на параллельный vitest-процесс → per-process TMP устраняет race. Аналогично #177 (test helper), но для output-каталогов `beforeAll`.
+
+## Pending
+- Issue #185: тот же bug class в `tests/e2e.test.ts` (не вошёл в список #183) — отдельный PR.
+
+## Watch out
+- `e2e.test.ts` всё ещё имеет общий `/tmp/draw-image-e2e` — параллельный запуск 10× vitest падает в этом файле (4/10 запусков), фикс трекается в #185. 7 зафиксированных файлов идут зелёные во всех 10 параллельных запусках.
+- Одиночный `npx vitest run`: 58/58 зелёные.
+- `mkdtempSync` не использовался — `process.pid` suffixed path достаточен для внешней параллельности (отдельные процессы vitest); для intra-process threads у vitest по умолчанию forks pool, PID разный у каждого воркера.
