Close the #714 remediation gap left at 943d402 where env-only mutation
profiles, REMOTES Timesheet defaults treated as explicit caller input, and
machine-dependent Git remotes produced false greens.
- Fail closed when mutations lack a config-backed profile with non-empty
allowed_repositories; env ops cannot invent mutation authority.
- Preserve omitted-vs-explicit org/repo provenance through the mutation
gate; omitted targets bind to the verified workspace repository.
- Prefer workspace-aligned Git remotes over historical Timesheet defaults
in MCP _resolve and CLI resolve_remote.
- Centralize deterministic config-backed mutation fixtures; migrate
mutation tests off env-only authority without weakening security
assertions.
Full suite: 2744 passed, 6 skipped.
Move @mcp.tool() from internal _list_open_pulls helper onto
gitea_lock_issue so author sessions can discover and call the
issue lock required by gitea_create_pr.
Add regression tests for MCP registration and create_pr lock flow.
