 ### Fixed
 
+- README / `@cedarjs/pg/vite-plus` Vite+ example: `dev` is now `cedarpg run --attach --mode=dev -- vp dev` (with `cache: false`). Vite+ `dependsOn` does not forward env and task `env` only passes through the `vp` process env, so the old `command: "vp dev"` + `env: ["DATABASE_URL"]` never saw the leased URL.
 - `cedarpg run` (plain and `--attach`) and `cedarpg studio` forward `SIGINT` / `SIGTERM` / `SIGHUP` to the child. A supervisor that signalled only the `cedarpg` process (Nx, pm2, `kill <pid>`) used to leave the child running. A child killed by a signal now exits with `128 + n` (130 for `SIGINT`, 143 for `SIGTERM`) instead of 1.
 - Ephemeral host cold start no longer deletes `/dev/shm/PostgreSQL.*` and `pgserve-*`. Those are live shared-memory segments of every Postgres on the machine. Running with `CI=true` or `CEDAR_PG_EPHEMERAL_HOST=1` next to a registered local host deleted that host's segment, and every new connection to it then failed with `58P01 could not open shared memory segment` until it was restarted. Cold start now removes only cedar-pg's own leftover data dir (`/dev/shm/cedar-pg-<uid>`). The `53100` / quota hint no longer recommends `rm /dev/shm/PostgreSQL.*`.
 - TEMPLATE `cloneWorkerDatabase` reuses the worker's `<template>_c_<workerId>` in Postgres across Jest test files. The `0.2.0-beta.0` fix cached the clone on `globalThis`, but Jest resets `globalThis` and the module registry for each test file. So the second file in a worker still ran `CREATE DATABASE` and failed with `database already exists`. The in-memory memo is removed; the database is the source of truth. As a result, calling it again with a different `root` / `name` in one process no longer throws: each call clones or reuses its own name. `smoke:pg` now runs two Jest files in one worker, after a seeded crashed run.

+Like Nx `dependsOn`, Vite+ `dependsOn` does not forward env, and task `env` only fingerprints and passes through variables already set in the `vp` process. So `dev` acquires once via `db:acquire`, then `cedarpg run --attach` hands the lease `DATABASE_URL` to `vp dev`. `test` needs no wrapper: the stock Vitest setup acquires and sets the URL itself.

 `cedarPgDev()` does not acquire. Keep `dependsOn: ["db:acquire"]`. On listen it prints a status panel (TTY, non-CI). Vite CLI shortcuts (`key` then Enter; also listed under `h`):
