# State Machines

## Document version

```text
acquired -> security_checked -> parsed -> normalized -> chunked
-> embedded -> indexed -> validated -> published
```

Terminal/alternatief:

- `quarantined`: securitygate faalde of vereist review;
- `failed`: technische fout met retryclassificatie;
- `superseded`: was gepubliceerd maar is vervangen;
- `retired`: bron verwijderd/retentie verlopen.

Alle transities zijn expliciet, geaudit en idempotent. `published` vereist dat alle voorafgaande artifacts duurzaam bestaan.

## Job

```text
pending -> ready -> leased -> running -> succeeded
                    |          \-> retry_wait -> ready
                    \-> expired -> ready
running -> failed_terminal
running -> cancelled
```

## Source sync

```text
idle -> scheduled -> scanning -> applying -> validating -> completed
                       \-> failed
```

## Index build

```text
created -> building -> validating -> ready -> active -> retired
                     \-> failed
```

Aliasactivatie mag alleen van `ready` naar `active`, met rollback naar vorige actieve build.
