Adds `GET /api/v1/system/health`, a structured read-only health surface for
automated readiness checks, and keeps `/health` as the cheap liveness probe.
webui/system_health.py composes a DTO from fail-soft dependency probes: the
control-plane database, the local checkout, and — opt-in via `?deep=1` — live
Gitea reachability, each carrying status, reason, and probe latency. Required
probes drive readiness; the optional Gitea probe can only degrade overall
status, because local inventory stays serveable when the remote is
unreachable. A probe that did not run leaves readiness incomplete rather than
silently passing.
Read-only throughout: the control-plane database is opened through a `mode=ro`
URI because `ControlPlaneDB.__init__` creates directories and runs migrations,
which a health check must never do. No restart or reload control is exposed;
those are Phase 2 and #630 forbids process-kill recovery.
No unproven claims: `stale_runtime.mutation_safe` is true only when the
runtime, checkout, and remote commits are all known and equal, and MCP
namespaces always report `unproven` because a web process cannot exercise the
IDE-managed client path (#543). Probe details are redacted at the browser
boundary — URLs lose userinfo and query strings, credential-shaped text is
masked.
`/health` is expanded additively: every MVP key is retained, plus `started_at`,
`uptime_seconds`, and a pointer to the versioned API. The versioned route
returns 503 when not ready so automation can branch on the status code alone.
Verified at master 9eb0f29: focused file 40 passed / 11 subtests; `-k "webui or
health"` 230 passed / 159 subtests; full suite 4358 passed with the 11
pre-existing master-drift failures unchanged from the clean-master baseline.

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):
./scripts/run-webui
Or directly:
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 |
WEBUI_REPO_ROOT |
repository root | Prompt library workflow hash root |
WEBUI_PROJECT_REGISTRY |
packaged JSON | Project registry path |
GITEA_MCP_CONFIG |
unset | Server-side MCP profile config (never sent to browser) |
GITEA_MCP_PROFILE |
unset | Active MCP profile name (server-side only) |
See webui-deployment.md for internal-only serving, Cloudflare Access/WARP/VPN guidance, and unsafe bind overrides (#435).
See
architecture/webui-control-plane-console-architecture-adr.md
for the console architecture: layer and authority boundaries, the redaction
boundary, /api/v1/... versioning, the target page map, and the phase gates
that govern when a write path may open (#632, epic #631).

local validator preview only (no Gitea mutations, no server-side storage).
System health API (#634)
GET /api/v1/system/health is the structured, read-only health surface for
automated readiness checks. It is the first console API under the /api/v1
prefix; the unversioned MVP exports remain as compatibility aliases.
/health is unchanged for existing consumers — every MVP key is still present
— and now also carries started_at, uptime_seconds, and a
system_health_api pointer. It stays deliberately cheap and runs no dependency
probe, because answering readiness costs real work.
Status codes. 200 when ready, 503 when a required dependency failed or
was never probed. Automation can branch on the code without parsing the body.
Query flags. The Gitea check is a network call, so it is opt-in:
GET /api/v1/system/health?deep=1 runs it and caches the result for
WEBUI_HEALTH_PROBE_TTL_SECONDS (default 15s) so dashboard polling does not
amplify into remote load. Without the flag that probe reports skipped.
Dependencies. control_plane_db and repository are required and drive
readiness. gitea is optional: when it fails the overall status degrades but
readiness.ready stays true, because local inventory is still serveable. Each
entry carries status, detail, required, and latency_ms.
Two honesty rules are worth knowing before reading the payload:
stale_runtime.mutation_safeis true only when the runtime, checkout, and remote-tracking commits are all known and equal. An unfetched remote is reported as indeterminate, never as safe.mcp_namespacesentries are alwaysunproven. A web process runs outside the IDE-managed MCP client and cannot invoke a namespace tool, so per #543 only aclient_namespaceprobe can prove that path.
Sample response (abridged, healthy):

],

"probe_errors": []
}
No restart, reload, or process-kill control is exposed here: those are Phase 2
at the earliest, and #630 forbids process-kill recovery outright. Every probe
opens its subject read-only — the control-plane database is opened through a
mode=ro URI so a health check can never create or migrate a schema.
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.
Deployment boundary (#435)
MVP serves on loopback by default. Binding 0.0.0.0 or :: is refused
unless WEBUI_ALLOW_PUBLIC_BIND=1. Non-loopback hosts log a warning unless
WEBUI_ALLOW_REMOTE_BIND=1. GET /health exposes deployment metadata.

## Tests (#436)
Run the full hermetic web UI suite (all `test_webui_*.py` modules):
```bash
./scripts/test-webui
CI / Jenkins multibranch can call the path-filtered gate (runs only when the
diff touches webui/, tests/test_webui_*, or web UI docs/scripts):
./scripts/ci-webui-check
WEBUI_CI_FORCE=1 ./scripts/ci-webui-check # always run
scripts/test-webui sets WEBUI_TEST_OFFLINE=1 by default. In that mode the
queue, lease, and runtime routes use empty offline snapshots instead of Gitea
credentials, so CI can run without MCP daemon credential access. Set
WEBUI_TEST_OFFLINE=0 only when deliberately validating live fetch behavior.
Or invoke unittest directly:
python3 -m unittest discover -s tests -p 'test_webui_*.py' -q
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.
