Merge branch 'master' into fix/issue-850-native-mcp-bootstrap

Post-merge cleanup previously continued past ownership-blocked remote
deletes, which skipped independently safe local worktree removal when the
only block was worktree_binding. Remove the clean owned worktree first,
reassess ownership, then delete the remote branch only if still safe.
Preserve fail-closed protection for dirty/foreign ownership categories.

Closes #851

+"""Sanctioned author issue worktree bootstrap for allocated issues (#850).
+
+Bootstraps an allocated author branch, canonical worktree under ``branches/``,
+worktree registration, issue lock, and lease/assignment binding without
+caller-side Git, Bash, or helper scripts.
+
+Features:
+1. Durable phase journal with read-after-write evidence for every phase.
+2. Idempotent replay handling via idempotency keys.
+3. Authoritative expected-base / concurrency-pin validation.
+4. Typed stale-pin refusal without silent rebasing or repointing.
+5. Canonical branches-root enforcement (path MUST be inside branches/).
+6. Preexisting work preservation (dirty tracked/untracked check, foreign ownership refusal).
+7. Compensating recovery limited strictly to artifacts created by this transition.
+8. Satisfiable exact_next_action for MCP scheduled workers.

-## Policy & guardrail visibility (#646)
+## Application shell — Phase 1 (#638)
 
-`/policy` (HTML) and `/api/v1/policy` (JSON) surface a **read-only** projection
-of the major workflow guardrails — role separation/RBAC, lease lifecycle,
-author worktree binding, merge confirmation, secret redaction, contamination
-containment, allocator policy, audit logging, and mutation gating. Each entry
-carries source pointers to the file/module/doc that owns it, a compact active
-value derived from the existing safe policy accessors, and — where a documented
-default is declared — a diff of active vs documented. The whole payload is run
-through the console redaction pass before it is emitted, so a planted or
-accidental secret degrades to the placeholder rather than reaching a client.
-The view never edits policy and exposes no gate-weakening toggle.
+The console shell (`webui/layout.py`) renders a grouped navigation driven by a
+single nav-config module, `webui/nav.py`. Nav groups follow the epic #631
+Phase 1 information architecture: **Health, Traffic, Runtime/Sessions,
+Projects, Inventory, Timeline, Policy** (placeholder), and **Insights**
+(placeholder). Live views and Phase 1 placeholders (`stub`) are declared in one
+place so the layout and the route table cannot drift.
+
+The header carries two read-only status badges — an **environment** badge
+(`local` for loopback binds, `remote` otherwise, derived from `WEBUI_HOST`) and
+a **mode: read-only** badge — plus a **Docs** link to this document. No
+privileged action controls are present in the Phase 1 shell.
+
+Not-yet-implemented surfaces (`/sessions`, `/inventory`, `/timeline`,
+`/policy`, `/insights`) resolve to graceful read-only stub pages instead of
+404s; their backing views land in later child issues of #631 (the inventory
+surfaces are backed by #636). Mutating methods on stub routes still fail closed
+with `read-only-mvp`.

-"""Read-only workflow policy and guardrail inventory for the web UI (#646).
-
-Policy and guardrails live in code, profiles, docs, and skills. An operator
-cannot *see* the active workflow policy configuration from the console without
-reading the repository tree. This module projects the major guardrails into a
-redacted, machine-readable inventory with source attribution (file / module /
-doc), so the console can render them as HTML tables with source pointers.
-
-Design constraints (Phase 3, #646):
-
-- **Read-only projection.** Nothing here edits policy or exposes a toggle that
-  could weaken a gate. It reports what is already enforced elsewhere.
-- **Source attribution without secrets.** Every guardrail carries pointers to
-  the file/module/doc that owns it. Live values are compact summaries derived
-  from the safe policy accessors that already exist (``rbac_matrix``,
-  ``redaction_policy``, ``audit_policy``); raw regex, tokens, and endpoints are
-  never embedded.
-- **Redact before emit.** ``snapshot_to_dict`` runs the whole payload through
-  ``console_redaction.redact_payload`` so a planted or accidental secret in any
-  projected value degrades to the placeholder rather than reaching a client.
-- **Fail soft.** A projection that raises is recorded as a per-entry error and
-  never takes the page down; a guardrail is still listed with its sources.
-- **Diff vs documented defaults where feasible.** When a guardrail declares a
-  documented invariant, the active projection is compared against it and the
-  result is reported; otherwise the diff is explicitly ``None`` with a reason.
