# oz0 replay start

> Usage and flags for oz0 replay start.

For: Operators and developers looking up a command.

Start a replay of the tenant's jobs that finished within --since (7 days by default, never past the namespace's history retention: a longer window is cut to it and the report says so), newest first, at most --max-jobs. Give exactly one candidate:

--policy FILE        a whole tool-policy document (JSON, the stored form: read_only, destructive, open_world, undeclared, rules, ...)
--promote ID,...     shadow rules to make act, by ID (oz0 tenant tool-policy show lists them)
--preset NAME        a shipped preset (untrusted-then-consequential, confidential-then-egress), or with --preset-rules
FILE a proposed level change: a JSON list of tool rules that act with NAME as their origin
--budget-usd, --budget-model-calls, --budget-children
budget and tree limits per job, decided again from the recorded usage

One replay per tenant runs at a time.

## Usage

```bash
oz0 replay start (--policy FILE | --promote ID,... | --preset NAME [--preset-rules FILE] | --budget-usd USD ...) [--since 7d] [--agent A] [flags]
```
