## What
Adds the ability to **automatically migrate the dedicated run-ops
database** (the NEW DB in the run-ops split), matching how every other
database in the system is migrated. Follow-up to the run-ops split
activation.
## Changes
- **Migrate runner** — new
`internal-packages/run-ops-database/scripts/migrate.mjs`, exposed as
`db:migrate:deploy` / `db:migrate:status`. Connects via
`RUN_OPS_DATABASE_URL` (the same var the app uses) and expands `${VAR}`
refs like Prisma's dotenv.
- **Self-host** — `docker/scripts/entrypoint.sh` runs the run-ops
migration on boot when the DB is configured, gated by
`SKIP_RUN_OPS_MIGRATIONS`. Single-DB installs never set the URL, so it's
a clean no-op.
- **Single env-var family** — the run-ops DB is now addressed by one
canonical `RUN_OPS_*` family, connect path and migrations resolving the
identical URL:
- `RUN_OPS_DATABASE_URL` (writer) — replaces `TASK_RUN_DATABASE_URL`
- `RUN_OPS_LEGACY_DATABASE_URL` — replaces
`TASK_RUN_LEGACY_DATABASE_URL`
- `RUN_OPS_DATABASE_READ_REPLICA_URL` — replaces
`TASK_RUN_DATABASE_READ_REPLICA_URL`
- the old `TASK_RUN_*` aliases, the `??` coalesce, the
`runOpsNewDatabaseUrl` indirection, and the migrate-only `directUrl` are
all removed (consumers read `env.RUN_OPS_DATABASE_URL` directly).
`directUrl` was dropped because it was only ever used by `prisma
migrate` (never the app runtime) to bypass a pooler for advisory locks —
premature here since the run-ops connection isn't wired to the app yet.
If a pooler is later introduced for the app, a direct URL can be
reintroduced then.
## Safety
- **Pure rename** — nothing deployed sets any `TASK_RUN_*` var (the
split isn't activated anywhere yet; `.env.example`, docker-compose, and
cloud already use `RUN_OPS_*`), so there is no config migration.
- **Single-DB / self-host** — no new required env var; entrypoint and
migrate are no-ops when `RUN_OPS_DATABASE_URL` is unset.
- **Cloud** — runs migrations as pre-deploy ECS tasks (companion cloud
PR), calling these same `db:migrate:deploy` / `db:migrate:status`
commands.
## Verification
- Live migration against a fresh scratch DB with only
`RUN_OPS_DATABASE_URL` set: both migrations applied, no `P1012`/`P1013`;
`${VAR}` expansion, idempotent re-run, `status`, and no-op skip all
pass.
- Schema parity 4/4; `typecheck --filter webapp` 18/18; affected
split/replication tests 34/34.
## Scope
This delivers automatic migrations only. Enabling the app to *use* the
new DB (setting `RUN_OPS_DATABASE_URL` + `RUN_OPS_SPLIT_ENABLED` on the
service) is a separate activation step.
