# Internal web UI — local development (#426)

Read-only MVP skeleton for the MCP Control Plane operator console. Gitea,
MCP capability gates, and `skills/llm-project-workflow/` remain the source of
truth; this UI only provides route stubs and layout.

## Prerequisites

- Python 3.11+ with project dependencies installed (`pip install -r requirements.txt`)
- No secrets in repo, config, or client bundle

## Start the server

From the repository root (or an issue worktree):

```bash
./scripts/run-webui
```

Or directly:

```bash
python3 -m webui
```

Optional environment variables:

| Variable | Default | Purpose |
|----------|---------|---------|
| `WEBUI_HOST` | `127.0.0.1` | Bind address (keep local for MVP) |
| `WEBUI_PORT` | `8765` | Listen port |

## Routes (MVP)

| Path | Description |
|------|-------------|
| `/` | Home / operator overview |
| `/health` | JSON liveness (`status`, `service`, `mode`, `timestamp`) |
| `/queue` | Live PR and issue queue dashboard (#429) |
| `/api/queue` | JSON queue export with pagination metadata |
| `/projects` | Project registry list (#427) |
| `/projects/{id}` | Project detail + onboarding checklist |
| `/api/projects` | JSON registry export |
| `/prompts` | Prompt library with per-prompt copy buttons (#428) |
| `/api/prompts` | JSON prompt export with workflow hashes |
| `/runtime` | MCP runtime health and stale detection (#430) |
| `/api/runtime` | JSON runtime health export |
| `/audit` | Report audit paste + validator preview (#431) |
| `/api/audit` | JSON validator preview (POST `report_text`, optional `task_kind`) |
| `/worktrees` | Worktree hygiene dashboard (#432) |
| `/api/worktrees` | JSON worktree scan with classifications and anomalies |
| `/actions` | Gated write-action registry — all disabled in MVP (#434) |
| `/api/actions` | JSON action registry with capability metadata |
| `/api/actions/{id}/preview` | Mutation ledger preview (GET, read-only) |
| `/leases` | Lease and collision visibility (#433) |
| `/api/leases` | JSON lease/collision export |

Most routes are GET-only. POST/PUT/PATCH/DELETE return `405` with
`read-only-mvp`, except `/audit` and `/api/audit` which accept POST for
local validator preview only (no Gitea mutations, no server-side storage).

## Report audit (#431)

Paste an LLM final report at `/audit` or POST JSON to `/api/audit`. The UI
reuses `final_report_validator` and review schema checks to surface missing
proof fields, wrong validation vocabulary, mutation contradictions, and a
suggested next prompt or issue-comment draft. Task kind can be auto-detected
or selected explicitly.

## Project registry (#427)

Versioned registry file: `webui/data/projects.registry.json` (schema version `1`).

Override path with `WEBUI_PROJECT_REGISTRY` when operators keep a machine-local
copy outside git. The registry stores repo identity, remotes, profile names,
workflow/schema path references, and onboarding checklist steps — never tokens
or credentials.

Seed entry: **Gitea-Tools** on `https://gitea.prgs.cc` with `prgs-author`,
`prgs-reviewer`, and `prgs-reconciler` profiles.

## Prompt library (#428)

Prompts are generated at load time from canonical workflow files under
`skills/llm-project-workflow/workflows/`. SHA-256 hashes are computed from
`WEBUI_REPO_ROOT` (defaults to the repository root). Prompt bodies are short
copy/paste starters; canonical workflow files remain the only full policy
source.

## Live queue dashboard (#429)

`/queue` loads open PRs and issues for the default registry project (seed:
**Gitea-Tools** on `https://gitea.prgs.cc`) using existing `gitea_auth` read
credentials. The UI surfaces pagination proof (returned count, pages fetched,
`has_more`, `inventory_complete`) and classification badges (`claimed`,
`blocked`, `in-review`, `duplicate`) when evidence exists.

If credentials are missing or the fetch fails, the page shows an explicit error
instead of an empty queue (fail closed).

## Gated actions (#434)

`/actions` registers future write actions (claim, comment, review, merge,
delete branch, create PR/issue). Each entry declares the MCP tool, required
permission, and profile role from `task_capability_map.py` — aligned with
`gitea_resolve_task_capability`. Buttons are disabled; previews always render
a mutation ledger. Direct `attempt_action` calls fail closed without invoking
MCP tools.

## Worktree hygiene (#432)

`/worktrees` scans local `branches/` directories and registered git worktrees.
Each entry is classified (`active-pr`, `active-issue`, `dirty`, `stale-clean`,
`detached-review`, `unsafe-unknown`, `orphan`). Missing preserved worktrees
referenced by the issue lock file are flagged as anomalies (#404). The page
includes a copy/paste canonical cleanup prompt only — no deletion actions.

Override scan root with `WEBUI_REPO_ROOT` (defaults to repository root).

## Lease visibility (#433)

`/leases` surfaces read-only lease and collision state: local issue lock file,
in-progress claim inventory (#268), reviewer PR lease comments when present
(`<!-- mcp-review-lease:v1 -->`, #407), duplicate open PRs per issue (#400),
and duplicate local branches per issue. Links to collision-history backend
issues (#267, #268, #400, #407) are included. No lease acquire/release from UI.

## Runtime health (#430)

`/runtime` surfaces read-only MCP/runtime diagnostics for the default registry
project: active profile and role kind, authenticated identity (when credentials
are available), config model/mode, local vs remote `master` SHA sync, shell
health, workflow/schema SHA-256 hashes, and stale-runtime warnings when the
checkout is behind merged safety-gate changes. Restart guidance links to #420;
no tokens or MCP restart actions are exposed.
