docs: design for authentication & authorization system

Add docs/auth.md describing the default-open auth/authz design: service
account and user principals, hashed bearer tokens, a path+capability ACL
model (read/write/delete/create), an observe-only enforcement middleware
gated by AUTH_ENFORCE, Vault mint/revoke integration with a companion
vault-plugin-secrets-artifactapi engine, OIDC/LDAP user login, and a
phased delivery plan.

+# Authentication & Authorization — Design
+
+Status: **proposed** (tracking issue #79)
+
+Today ArtifactAPI has no authentication: every proxy and management request is
+served unconditionally. This document describes an auth/authz system that adds
+identity and path-scoped authorization **without changing behaviour until an
+operator turns enforcement on** — the default policy is fully open.
+
+## Goals
+
+- Identify callers as one of two principal kinds: **service accounts** and **users**.
+- Authorize each request against a **path + capability** ACL model.
+- Let **Vault/OpenBao** mint short-lived tokens so the Terraform provider can get
+  just-in-time credentials to make config changes.
+- Ship **default-open**: an unconfigured deployment behaves exactly as today.
+
+## Non-goals (initial phase)
+
+- Per-object encryption, signing, or content trust.
+- Rate limiting / quotas (separate concern).
+- Multi-tenancy beyond what path ACLs express.
+
+## Principals
+
+| Kind | Authenticates with | Created by | Lifetime |
+|---|---|---|---|
+| Service account — static token | `Authorization: Bearer <token>` | admin via management API | until revoked |
+| Service account — dynamic token | `Authorization: Bearer <token>` | Vault secrets engine → mint endpoint | lease TTL (auto-revoked) |
+| User | UI session cookie (OIDC/LDAP login) | external IdP, first-seen on login | session TTL |
+
+A **service account** is a named identity holding a set of ACL grants. It may
+have any number of associated tokens (static, or dynamic ones minted by Vault).
+A **user** is an identity resolved from an external IdP; group membership from
+the IdP maps to ACL grants.
+
+## Tokens
+
+- Format: `aapi_<base62(32 random bytes)>`. The `aapi_` prefix makes tokens
+  greppable and lets us reject obviously-malformed values cheaply.
+- Storage: only the **SHA-256 of the token** is stored, never the plaintext.
+  Lookup hashes the presented token and matches by hash.
+- Each token row carries: id, principal (service account) ref, sha256, optional
+  label, `expires_at` (null = non-expiring), `created_at`, `last_used_at`.
+- Revocation: delete the row (static) or Vault lease revoke → mint endpoint
+  revoke (dynamic).
+
+## ACL model
+
+A grant is `(path_pattern, capability)`. A principal is allowed an action iff at
+least one of its grants matches the request's resource path and capability.
+
+### Resource paths
+
+```
+remote/<remote-name>/<path-in-remote>     # proxy + local repo objects
+virtual/<virtual-name>/<path>             # virtual repo reads
+admin/remotes/<remote-name>               # manage a remote definition
+admin/virtuals/<virtual-name>             # manage a virtual definition
+admin/principals/<name>                   # manage service accounts / tokens
+```
+
+Patterns support a trailing `*` wildcard and `<segment>/*` prefixes, e.g.
+`remote/dockerhub/*`, `remote/*`, `admin/*`. Matching is longest-prefix by
+segment; an exact match always wins over a wildcard.
+
+### Capabilities
+
+| Capability | Meaning for `remote/...` | Meaning for `admin/...` |
+|---|---|---|
+| `read` | GET/HEAD an artifact | GET a definition |
+| `create` | first upload of a new local file | create a new definition |
+| `write` | overwrite / re-publish | update an existing definition |
+| `delete` | remove an object | delete a definition |
+
+The HTTP layer maps each route to `(resource path, capability)`:
+
+| Route | Resource | Capability |
+|---|---|---|
+| `GET /api/v1/remote/{r}/*`, `/v2/{r}/*` | `remote/{r}/{path}` | `read` |
+| `GET /api/v1/virtual/{v}/*` | `virtual/{v}/{path}` | `read` |
+| `PUT /api/v2/remotes/{r}/files/*` (new file) | `remote/{r}/{path}` | `create` |
+| `PUT ...` (existing file) | `remote/{r}/{path}` | `write` |
+| `DELETE /api/v2/remotes/{r}/files/*` | `remote/{r}/{path}` | `delete` |
+| `POST /api/v2/remotes` | `admin/remotes/{name}` | `create` |
+| `PUT /api/v2/remotes/{r}` | `admin/remotes/{r}` | `write` |
+| `DELETE /api/v2/remotes/{r}` | `admin/remotes/{r}` | `delete` |
+
+## Enforcement middleware & default-open
+
+A single middleware runs before the proxy/management handlers:
+
+1. Resolve the principal from the request (bearer token → service account, or
+   session cookie → user). No credential → the **anonymous** principal.
+2. Compute `(resource, capability)` for the route.
+3. If **enforcement is disabled** (default), allow. Otherwise, evaluate the
+   principal's grants (including the anonymous principal's grants) and allow iff
+   a grant matches; else 401 (no/invalid credential) or 403 (authenticated but
+   unauthorized).
+
+Enforcement is controlled by a single setting, `AUTH_ENFORCE` (default `false`).
+While `false`, the middleware still *resolves* the principal (so `last_used_at`
+and audit logging work) but never denies — making rollout observable before it
+is enforced. The **anonymous** principal is seeded with `*` → all capabilities,
+so even flipping `AUTH_ENFORCE=true` with no other config keeps the deployment
+open until an admin tightens the anonymous grants.
+
+## Vault integration
+
+### Mint endpoint (artifactapi side)
+
+`POST /api/v2/auth/tokens:mint` — restricted to callers Vault trusts. It creates
+a dynamic token bound to a named service account with a caller-supplied TTL, and
+returns the plaintext once. `DELETE /api/v2/auth/tokens/{id}` revokes it.
+
+Trust between Vault and artifactapi: a dedicated **bootstrap service account**
+whose static token is stored in Vault's engine `config`. The mint endpoint
+requires `admin/principals/*: write`. (mTLS is a future hardening option.)
+
+### `vault-plugin-secrets-artifactapi` (new repo)
+
+Mirrors [`vault-plugin-secrets-litellm`](https://git.unkin.net/unkin/vault-plugin-secrets-litellm):
+HashiCorp `vault/sdk`, OpenBao-compatible single binary. Paths:
+
+- `config` — artifactapi base URL + bootstrap token.
+- `roles/<name>` — target service account + default/max TTL.
+- `creds/<name>` — mint a dynamic token (calls the mint endpoint); the Vault
+  lease's revoke calls the revoke endpoint.
+
+E2e (`make e2e`) spins Postgres + MinIO + Redis + artifactapi + Vault + OpenBao
+in Docker and exercises the full lease lifecycle against both engines. On the
+Fedora host all bind mounts need `:z` (SELinux).
+
+## User login (OIDC/LDAP) & UI
+
+- `GET /api/v2/auth/login` starts an OIDC auth-code flow (or LDAP bind form);
+  `GET /api/v2/auth/callback` establishes a signed session cookie.
+- IdP groups map to service-account-style grants via configurable group→grant
+  rules. Existing infra: `terraform-authentik`, `terraform-ldap`.
+- The React UI gains a login state and sends the session cookie; management
+  screens hide actions the principal lacks.
+
+## Terraform provider
+
+`terraform-provider-artifactapi` gains a `token` attribute (and
+`ARTIFACTAPI_TOKEN` env var) sent as `Authorization: Bearer`. In CI the token is
+sourced from the Vault engine above, so config changes use short-lived creds.
+
+## Data model (new tables, additive migration)
+
+```sql
+service_accounts(name PK, description, disabled, created_at)
+auth_tokens(id PK, principal TEXT REFERENCES service_accounts(name) ON DELETE CASCADE,
+            token_sha256 TEXT UNIQUE, label, expires_at, created_at, last_used_at)
+acl_grants(id PK, principal TEXT, path_pattern TEXT, capability TEXT,
+           UNIQUE(principal, path_pattern, capability))
+-- principal = a service account name, the reserved 'anonymous', or 'user:<sub>'
+```
+
+All tables are created with `CREATE TABLE IF NOT EXISTS` alongside the existing
+inline migrations; adding them changes no current behaviour.
+
+## Rollout / phased delivery
+
+Each phase is a separate PR; the system stays open until phase 6 is deliberately
+enabled.
+
+1. **Data model + resolution** — tables, token hashing, principal resolution
+   middleware in **observe-only** mode (never denies). Seed anonymous `*`.
+2. **ACL evaluation** — grant matching + `(resource, capability)` route mapping,
+   still gated by `AUTH_ENFORCE=false`.
+3. **Management API** — CRUD for service accounts, tokens, grants.
+4. **Vault mint/revoke endpoints** + bootstrap trust.
+5. **`vault-plugin-secrets-artifactapi`** (new repo) + `terraform-vault` role,
+   policies; `argocd-apps` deploy.
+6. **OIDC/LDAP user login + UI**, Terraform provider `token`, and the switch to
+   enable enforcement in an environment.
+
+## Cross-repo dependencies
+
+- `terraform-vault` — mount the secrets engine, define `roles/*`, ACL policies,
+  and the K8s auth role the Terraform CI uses.
+- `argocd-apps` — deploy the plugin sidecar/init and any ServiceAccount.
+- `terraform-provider-artifactapi` — `token` attribute.
+- `terraform-authentik` / `terraform-ldap` — IdP client + group mappings.
