# Project registry API (#635)
|
||||
|
||||
Phase 1 of the [console architecture ADR](architecture/webui-control-plane-console-architecture-adr.md)
|
||||
gives the project registry a versioned, read-only API. This document is the
|
||||
field-by-field contract for that API and for the registry file behind it.
|
||||
|
||||
Everything here is **read-only**. The console never writes the registry; an
|
||||
operator edits the JSON file, and an invalid file fails closed rather than
|
||||
rendering a partial inventory.
|
||||
|
||||
## Routes
|
||||
|
||||
| Route | Method | Description |
|
||||
|-------|--------|-------------|
|
||||
| `/api/v1/projects` | GET | Versioned registry export: all projects, with provenance |
|
||||
| `/api/v1/projects/{project_id}` | GET | Single project; `404` with `project_not_found` when unknown |
|
||||
| `/api/projects` | GET | Unversioned MVP alias (#427), retained for all of Phase 1 |
|
||||
| `/projects` | GET | HTML list — status and onboarding progress per project |
|
||||
| `/projects/{project_id}` | GET | HTML detail — identity, profiles, paths, checklist |
|
||||
|
||||
Per ADR section 6 the unversioned alias may be retired no earlier than Phase 2,
|
||||
and only after this document and `webui-local-dev.md` record the swap. The alias
|
||||
returns the same payload as `/api/v1/projects`, including the legacy `version`
|
||||
and `source_path` keys #427 consumers already read.
|
||||
|
||||
The HTML views render from the same DTO the JSON routes serialize
|
||||
(`project_to_dict`), so the console and the API cannot disagree about a
|
||||
project's status or onboarding progress.
|
||||
|
||||
## Registry file
|
||||
|
||||
Default location: `webui/data/projects.registry.json`. Override with the
|
||||
`WEBUI_PROJECT_REGISTRY` environment variable.
|
||||
|
||||
Schema versions: **1** and **2** are accepted; **2** is current. A version 1
|
||||
file loads unchanged and is normalized with the documented defaults, so an
|
||||
existing operator registry keeps working without edits.
|
||||
|
||||
### Root
|
||||
|
||||
| Field | Type | Required | Notes |
|
||||
|-------|------|----------|-------|
|
||||
| `version` | int | yes | `1` or `2`. Anything else fails closed |
|
||||
| `projects` | array | yes | Must be non-empty |
|
||||
|
||||
### Project
|
||||
|
||||
| Field | Type | Required | Default | Notes |
|
||||
|-------|------|----------|---------|-------|
|
||||
| `id` | string | yes | — | Stable registry id used in URLs |
|
||||
| `repo_name` | string | yes | — | Gitea repository name |
|
||||
| `gitea_owner` | string | yes | — | Owning org or user |
|
||||
| `remote_host` | string | yes | — | Instance base URL, no credentials |
|
||||
| `remote_name` | string | no | `null` | Logical remote label, e.g. `prgs` (v2) |
|
||||
| `default_branch` | string | yes | — | Stable branch name |
|
||||
| `local_checkout_path` | string | yes | — | Control checkout path |
|
||||
| `status` | string | no | `active` | `active`, `onboarding`, `paused`, `archived` (v2) |
|
||||
| `profiles` | object | yes | — | Must map `author`, `reviewer`, `reconciler` |
|
||||
| `workflow_paths` | object | yes | — | Non-empty; label to repo-relative path |
|
||||
| `schema_paths` | object | no | `{}` | Label to repo-relative path |
|
||||
| `onboarding_checklist` | array | no | `[]` | See below |
|
||||
| `last_seen_health` | object | no | `null` | Redacted health only (v2) |
|
||||
|
||||
### Onboarding step
|
||||
|
||||
| Field | Type | Required | Default | Notes |
|
||||
|-------|------|----------|---------|-------|
|
||||
| `id` | string | yes | — | Stable step id |
|
||||
| `title` | string | yes | — | Short operator-facing label |
|
||||
| `description` | string | yes | — | Self-contained; assumes no chat history |
|
||||
| `state` | string | no | `pending` | `complete`, `pending`, `blocked`, `not_applicable` (v2) |
|
||||
| `required` | bool | no | `true` | Optional steps never block readiness (v2) |
|
||||
|
||||
### Last-seen health
|
||||
|
||||
| Field | Type | Required | Notes |
|
||||
|-------|------|----------|-------|
|
||||
| `status` | string | no (default `unknown`) | `healthy`, `degraded`, `unreachable`, `unknown` |
|
||||
| `checked_at` | string | no | ISO-8601 UTC timestamp, e.g. `2026-01-01T00:00:00Z` |
|
||||
| `detail` | string | no | Short redacted note |
|
||||
|
||||
Health is recorded metadata, not a live probe: Phase 1 performs no outbound
|
||||
health checks. Endpoints, tokens, and keychain identifiers must never appear
|
||||
here.
|
||||
|
||||
## Response shape
|
||||
|
||||
`GET /api/v1/projects`:
|
||||
|
||||
```json
|
||||
{
|
||||
"api_version": "v1",
|
||||
"schema_version": 2,
|
||||
"version": 2,
|
||||
"source_path": "/path/to/webui/data/projects.registry.json",
|
||||
"source": {
|
||||
"kind": "file",
|
||||
"path": "/path/to/webui/data/projects.registry.json",
|
||||
"inventory_complete": true
|
||||
},
|
||||
"project_count": 1,
|
||||
"projects": [
|
||||
{
|
||||
"id": "example",
|
||||
"repo_name": "Example",
|
||||
"gitea_owner": "Org",
|
||||
"repo_full_name": "Org/Example",
|
||||
"remote_host": "https://gitea.example.invalid",
|
||||
"remote_name": "example-remote",
|
||||
"default_branch": "main",
|
||||
"local_checkout_path": ".",
|
||||
"status": "active",
|
||||
"profiles": {"author": "...", "reviewer": "...", "reconciler": "..."},
|
||||
"workflow_paths": {"skill": "skills/..."},
|
||||
"schema_paths": {},
|
||||
"onboarding_checklist": [
|
||||
{
|
||||
"id": "profiles",
|
||||
"title": "Configure execution profiles",
|
||||
"description": "...",
|
||||
"state": "complete",
|
||||
"required": true
|
||||
}
|
||||
],
|
||||
"onboarding_summary": {
|
||||
"total": 1,
|
||||
"complete": 1,
|
||||
"pending": 0,
|
||||
"blocked": 0,
|
||||
"not_applicable": 0,
|
||||
"required_outstanding": 0,
|
||||
"onboarding_complete": true
|
||||
},
|
||||
"last_seen_health": null
|
||||
}
|
||||
]
|
||||
}
|
||||
```
|
||||
|
||||
`GET /api/v1/projects/{project_id}` returns `api_version`, `schema_version`,
|
||||
`source`, and a single `project` object with the same fields.
|
||||
|
||||
The `source` block satisfies the ADR section 6 provenance rule: every payload
|
||||
states where the data came from and whether the inventory is complete. A
|
||||
file-backed registry is always complete — there is no pagination to truncate it.
|
||||
|
||||
`onboarding_summary` is derived, never stored. `required_outstanding` counts
|
||||
steps that are `required` **and** in state `pending` or `blocked`;
|
||||
`onboarding_complete` is true when that count is zero.
|
||||
|
||||
## Fail-closed errors
|
||||
|
||||
Validation failures raise `RegistryError`, which routes render instead of a
|
||||
traceback.
|
||||
|
||||
`404` — unknown project id on `/api/v1/projects/{project_id}`:
|
||||
|
||||
```json
|
||||
{
|
||||
"error": "project_not_found",
|
||||
"project_id": "not-registered",
|
||||
"known_project_ids": ["example"],
|
||||
"remediation": "Request one of the known project ids, or add the project ...",
|
||||
"source": {"kind": "file", "path": "...", "inventory_complete": true}
|
||||
}
|
||||
```
|
||||
|
||||
`500` — invalid registry, on both the versioned route and the alias:
|
||||
|
||||
```json
|
||||
{
|
||||
"error": "registry_invalid",
|
||||
"detail": "unsupported registry version: 42",
|
||||
"remediation": "Set 'version' to one of 1, 2 (current schema is 2) ...",
|
||||
"field_path": "version",
|
||||
"source_path": "/path/to/registry.json"
|
||||
}
|
||||
```
|
||||
|
||||
`field_path` points at the offending location (`projects[0].profiles.reconciler`,
|
||||
`projects[0].onboarding_checklist[2].state`, and so on). The HTML routes render
|
||||
the same detail, field, source, and remediation on a "Project registry
|
||||
unavailable" page.
|
||||
|
||||
Conditions that fail closed:
|
||||
|
||||
* file missing or unreadable;
|
||||
* invalid JSON (the remediation names line and column);
|
||||
* root not an object, or `projects` missing/empty;
|
||||
* unsupported `version`;
|
||||
* a credential-shaped key anywhere in the file (`token`, `*_secret`, `auth_*`, and similar);
|
||||
* a project missing a required field, or missing an `author`/`reviewer`/`reconciler` profile;
|
||||
* an unknown `status`, onboarding `state`, or health `status`.
|
||||
|
||||
## Credential rule
|
||||
|
||||
The registry stores redacted metadata only. Credential-shaped keys are
|
||||
rejected at load time, before any DTO is built, consistent with
|
||||
[safety-model.md](safety-model.md) and
|
||||
[credential-isolation.md](credential-isolation.md). Tokens live in the keychain
|
||||
and are resolved server-side by `gitea_auth`.
|
||||
|
||||
## Migrating a version 1 registry
|
||||
|
||||
1. Set `"version": 2`.
|
||||
2. Optionally add `"status"` per project (omitted means `active`).
|
||||
3. Optionally add `"remote_name"` per project.
|
||||
4. Optionally add `"state"` and `"required"` to each onboarding step (omitted
|
||||
means `pending` and `true`).
|
||||
5. Optionally add `"last_seen_health"`.
|
||||
|
||||
No step is mandatory: a version 1 file keeps loading. Bumping the version only
|
||||
declares that the file may use the v2 fields.
