docs(compliance): add docs/compliance reference examples and README

Adds docs/compliance/ as the canonical onboarding reference for the
compliance module, covering every field in each generated YAML artifact
with inline annotations and explaining the docs/compliance/ (examples)
vs compliance/ (live artifacts) split.

# docs/compliance — reference examples for the compliance module
This folder contains **annotated example files** that document the schema used by the compliance generators. It is **not** the live compliance artifact directory.
| Location | Contents | Edit manually? |
| -------------------------------- | ------------------------------- | ----------------------- |
| `docs/compliance/` (this folder) | Schema examples and this README | Yes — static reference |
| `compliance/` (repo root) | Live generated artifacts | No — run the generators |
---
## What each file in `compliance/` contains
### `compliance/data-map.yml`
A field-level PII inventory derived from every Payload collection in the workspace.
For each collection the generator records:
- **auth** — whether the collection has Payload authentication enabled
- **piiFields** — every field carrying a `custom.pii` tag, plus Payload auth defaults (`email`, etc.) for auth collections
Each PII field entry captures the **category** (e.g. `contact-email`, `identification-username`), one or more **purposes** (e.g. `account-authentication`, `service-delivery`), whether the field is **exportable** (GDPR Art. 15) and **restrictable** (GDPR Art. 18), the **source** (`field-tag`, `auth-default`, or `auth-override`), and an optional per-field **retention** override.
See `docs/compliance/data-map.example.yml` for every field with annotations.
### `compliance/retention-policy.yml`
A collection-level retention schedule derived from `custom.retention` blocks in Payload collection configs.
For each collection the generator records:
- **purgeSchedule** — cadence for the background purge job (`daily` | `weekly` | `monthly`); **required** on every collection
- **activeRetention** _(optional)_ — how long to keep a live record before triggering deletion
- **coldArchive** _(optional)_ — long-term archive window for regulatory fixed-term obligations
- **postDeletion** — what happens after a DSR erasure or account-closure request (`hard-delete` or `pseudonymize` with an ISO 8601 grace period)
See `docs/compliance/retention-policy.example.yml` for every field with annotations.
### `compliance/sub-processors.yml`
An inventory of every third-party processor that receives personal data from this application. Entries come from two sources and are merged at emit time:
1. **Library decision traces** (`docs/library-decisions/*.md`) — npm packages where `is-sub-processor: true` in the frontmatter.
2. **Manual entries** (`compliance/sub-processors.manual.yml`) — non-npm vendors (REST APIs, SaaS integrations, infrastructure providers).
Each entry records the **package** name (sort key), **data-sent** description, **region**, **dpa-signed** and **sccs-required** booleans, a **contact** URL, the **decision** status, and a **source** discriminator (`library-trace` or `manual`).
See `docs/compliance/sub-processors.example.yml` for both entry kinds with annotations.
---
## How the files are generated
All three artifacts are regenerated together:
```bash
pnpm compliance:emit-all
```
Or individually:
```bash
pnpm compliance:data-map # writes compliance/data-map.yml
pnpm compliance:retention-policy # writes compliance/retention-policy.yml
pnpm compliance:sub-processors # writes compliance/sub-processors.yml
```
Each script also supports two diagnostic modes:
```bash
pnpm compliance:data-map -- --print # write YAML to stdout (no file written)
pnpm compliance:data-map -- --check # diff vs committed file; exit 1 on mismatch
```
`--check` mode is used by the pre-commit hook and CI drift gate to detect uncommitted changes to collection configs that would cause `compliance/*.yml` to drift from the source of truth.
---
## Keeping `compliance/*.yml` up to date
Regenerate and commit the artifacts whenever you:
- Add or modify a Payload collection in any feature package
- Change `custom.pii` tags on collection fields
- Change `custom.retention` blocks on collection configs
- Add a library decision trace with `is-sub-processor: true`
- Add or update entries in `compliance/sub-processors.manual.yml`
The pre-commit hook and CI gate run `emit-all --check` and will reject the commit or PR if the committed YAML is stale.
---
## Annotating PII fields in a collection
Add `custom.pii` to any field in a Payload collection config:
```ts
{
name: "phone",
type: "text",
custom: {
pii: {
category: "contact-phone", // PiiCategory
purpose: ["transactional-notifications"], // DataProcessingPurpose[]
exportable: true,
restrictable: true,
// Optional per-field retention override:
retention: {
duration: "P1Y", // ISO 8601
trigger: "from-last-access", // "from-creation" | "from-last-access" | "after-deletion"
action: "hard-delete", // "hard-delete" | "pseudonymize"
},
},
},
},
```
For auth collections, `email` is automatically classified via `PAYLOAD_AUTH_PII_DEFAULTS`. Override per-collection via `custom.authPii`:
```ts
{
slug: "members",
auth: true,
custom: {
authPii: {
// Extend or replace the email default for this collection only:
email: {
category: "contact-email",
purpose: ["account-authentication", "marketing-communications"],
exportable: true,
restrictable: true,
},
},
},
}
```
See `packages/core-shared/src/payload/pii-types.ts` for the full list of allowed `PiiCategory` and `DataProcessingPurpose` values.
---
## Annotating retention policy in a collection
Add `custom.retention` to the collection config. `purgeSchedule` is **required** on every collection; the other fields are optional:
```ts
{
slug: "profiles",
custom: {
retention: {
purgeSchedule: "daily", // Required: "daily" | "weekly" | "monthly"
activeRetention: { // Optional: expire live records
duration: "P2Y",
trigger: "from-last-access",
},
coldArchive: { // Optional: regulatory fixed-term archive
duration: "P7Y",
trigger: "from-creation",
},
postDeletion: { // Optional: override the default post-deletion behaviour
action: "pseudonymize", // "hard-delete" | "pseudonymize"
duration: "P30D",
trigger: "after-deletion",
},
},
},
}
```

## Registering a sub-processor
### From an npm library (preferred)
Add sub-processor fields to the library's decision trace in `docs/library-decisions/`:
```markdown
---
package: "@acme/notifications-sdk"
version: "^2.3.0"
decision: approved
is-sub-processor: true
data-sent: "user email address and display name for transactional notification delivery"
region: EU
dpa-signed: true
sccs-required: false
contact: https://acme-sdk.example/privacy/dpa
---
```
Run `pnpm compliance:sub-processors` to regenerate.
### Non-npm vendors (REST APIs, SaaS, infrastructure)
Create `compliance/sub-processors.manual.yml` if it doesn't already exist and add an entry:
```yaml
- package: acme-email-service # slug-style identifier (no @ prefix)
version: "REST API v3"
data-sent: "user email address and message body for transactional email delivery"
region: EU
dpa-signed: true
sccs-required: false
contact: https://acme-email.example/legal/dpa
decision: approved
```
`compliance/sub-processors.manual.yml` is a hand-authored file committed to the repository alongside the generated `compliance/sub-processors.yml`. The generator merges manual entries at emit time and injects `source: "manual"` automatically. Do **not** add `source:` manually — it will be overwritten.
Run `pnpm compliance:sub-processors` after any change to regenerate `compliance/sub-processors.yml`.
---
## `sccs-required` guidance
Set `sccs-required: true` when:
- The vendor's primary data-residency region is outside the EEA **and**
- There is no EU adequacy decision covering that country (e.g. US before Privacy Shield replacement, India, most of Asia-Pacific)
Set `sccs-required: false` when:
- The vendor is EU/EEA-resident, **or**
- The vendor's country has a current EU adequacy decision, **or**
- The data transfer is covered by Binding Corporate Rules
When `sccs-required: true`, ensure SCCs are incorporated in the DPA before marking `dpa-signed: true`.
