+# AGENTS_ARQUITECTURA.md
+
+These rules complement `AGENTS.md` and are mandatory whenever the task changes project structure, C# architecture, database access, repositories, services, contracts, models, or application transactions.
+
+## Project folder rules
+
+Use this base structure:
+
+```text
+SIG.Web/
+  App_Code/
+    Infrastructure/
+    Sql/
+    Repositories/
+    Security/
+    Utilities/
+    Contracts/
+    Models/
+    Services/
+  Styles/
+  Scripts/
+  Metronic/
+  Site.master
+  Site.master.cs
+  Login.aspx
+  Login.aspx.cs
+  Inicio.aspx
+  Inicio.aspx.cs
+  BundleConfig.cs
+  Global.asax
+  Global.asax.cs
+  Web.config
+```
+
+Rules:
+
+- The active application uses the ASP.NET Web Site runtime-compilation model.
+- Shared C# source belongs in the exact special folder `App_Code`.
+- Pages, master pages, controls, handlers, and `Global.asax` use `CodeFile` or source compiled from `App_Code`; do not introduce new `CodeBehind` dependencies on `SIG.Web.dll`.
+- Keep third-party and external assemblies in `bin`, but do not build or deploy a project assembly named `SIG.Web.dll`.
+- Do not place database access directly inside `.aspx.cs`, `.ascx.cs`, or `Site.master.cs`.
+- Database-related helpers go under `App_Code/Sql` or a clearly named SQL/data folder.
+- Business access goes through `Contracts` and `Services`.
+- The active Web Site does not use explicit project compilation entries; C# files under `App_Code` compile automatically at runtime.
+
+---
+
+## Contract rules
+
+Contracts belong in `/Contracts`.
+
+Current minimum contracts:
+
+```text
+Contracts/IAuthContract.cs
+Contracts/IUserSessionContract.cs
+Contracts/IMenuContract.cs
+Contracts/IMasterPageContract.cs
+```
+
+Suggested future contracts:
+
+```text
+Contracts/IPermissionContract.cs
+Contracts/INotificationContract.cs
+Contracts/ICatalogSearchContract.cs
+Contracts/IAuditContract.cs
+Contracts/ICurrentCompanyContract.cs
+```
+
+Rules:
+
+- Pages call contracts, not SQL classes.
+- Master page calls contracts, not SQL classes.
+- Login calls contracts, not SQL classes.
+- Contracts must return models, DTOs, or result objects, not raw `DataTable` unless migrating legacy code.
+- If legacy `DataTable` is required, isolate it behind a contract and document why.
+
+---
+
+## Repository ownership rules
+
+Repository ownership is determined by the data domain and stored-procedure prefix, not by the page or feature that currently consumes the data.
+
+- Procedures named `PA_Gral_*` belong behind contracts and repositories under `Contracts/General` and `Repositories/General`.
+- General catalogs such as states, countries, municipalities, neighborhoods, and postal codes must not be placed in a security, registration, sales, or page-specific repository.
+- A feature service such as public registration may orchestrate both its feature repository and `IGeneralCatalogRepository`, but it must not move general catalog access into the feature repository.
+- Apply the same ownership rule to future procedure families: `PA_Sis_*` belongs to security/system infrastructure, `PA_Tra_*` to procedures, `PA_Vta_*` to sales, and so on.
+
+## Database executor ownership rules
+
+- `IDbExecutor`, `DbExecutor`, `StoredProcedureCommand`, `IDbCommand`, and direct stored-procedure execution may only be used inside classes under `Repositories` or repository database infrastructure.
+- Services must not reference or receive `IDbExecutor`, create database commands, execute readers, or call stored procedures directly.
+- A service that needs persisted data must depend on a repository contract. The concrete repository receives `IDbExecutor` and owns parameter configuration and result mapping.
+- Keep the `DbExecutor` implementation under `Repositories/Database`; do not place it under `Services` or expose it publicly through `AppServices`.
+
+---
+
+## Service rules
+
+Services belong in `/Services`.
+
+Current starter services may include:
+
+```text
+Services/ContractRegistry.cs
+Services/DummyAuthContract.cs
+Services/UserSessionContract.cs
+Services/DummyMenuContract.cs
+Services/MasterPageContract.cs
+```
+
+Rules:
+
+- `ContractRegistry` may be used as a simple manual dependency resolver for WebForms.
+- Do not introduce a complex dependency injection framework unless required.
+- Services may depend on SQL helpers/repositories.
+- `.aspx.cs` files should be thin and delegate work to services.
+- Keep dummy services separate from SQL-backed services.
+- Services own application transactions when one business operation performs one or more repository mutations.
+- Use `TransactionLogic` inside a `using` block around the repository calls and invoke `Commit()` only after every required repository result succeeds.
+- Pages and repositories must not create, commit, roll back, or dispose application transactions.
+- Repositories participate through the ambient `TransactionScope`; connection strings used for transactional work must not set `Enlist=false`.
+- Select `TransactionScopeOption`, isolation level, and timeout in the service according to the business operation. Use `RequiresNew` or `Suppress` only when that behavior is intentional and documented by the call site.
+- Do not include slow external operations such as SMTP or HTTP calls inside a database transaction.
+
+---
+
+## Model rules
+
+Models belong in `/Models`.
+
+Current starter models may include:
+
+```text
+Models/AppUser.cs
+Models/LoginResult.cs
+Models/MenuItemModel.cs
+Models/MasterLayoutModel.cs
+Models/BreadcrumbItem.cs
+```
+
+Rules:
+
+- Use models to move data between contracts and WebForms pages.
+- Do not pass anonymous objects across layers.
+- Do not expose SQL connection classes or `SqlDataReader` from services to pages.
+- Keep models simple and serializable when possible.
+
+---
+
+## Database and SQL structure rules
+
+All database connection structure must be centralized under `App_Code/Sql` or an equivalent SQL/data folder.
+
+Current starter SQL structure:
+
+```text
+App_Code/Sql/ConnectionNames.cs
+App_Code/Sql/IConnectionStringProvider.cs
+App_Code/Sql/WebConfigConnectionStringProvider.cs
+App_Code/Sql/SqlConnectionFactory.cs
+App_Code/Sql/SqlQueryExecutor.cs
+```
+
+Rules:
+
+- Define connection names in one place.
+- Read connection strings from `Web.config`.
+- Do not hardcode connection strings in pages, master, controls, or services.
+- Do not create `SqlConnection` directly in `.aspx.cs`.
+- Do not create `SqlCommand` directly in `.aspx.cs`.
+- Use repositories or SQL executor classes behind contracts.
+- All application database reads and writes must use stored procedures; inline SQL in C# is prohibited.
+- Access to modules and catalogs is controlled by the menu and page-access layer. Reusable catalog stored procedures must not query `Sis_Usuarios`, restrict execution by `CveRol`, or return access-denied messages for module authorization.
+- Keep `@CveUsuarioEjecuta` in catalog procedures for the required signature and auditing when applicable, not to authorize access to the module.
+- Do not invent or add authorization, role, user-client association, ownership, or business-prerequisite validations to any stored procedure unless the user explicitly requests that exact validation. The user prefers to add those validations manually.
+- Mandatory: read and follow `AGENTS_STORED_PROCEDURES.md` for naming, output parameters, TRY/CATCH, logging, transactions, and physical deletion.
+- Mandatory: read and follow `AGENTS_DATA_READER_MAPPING.md` for object, list, `DataTable`, and `JArray` result mapping.
+- Mandatory: read and follow `AGENTS_DATABASE_ERROR_LOGGING.md` for safe parameter logging and reproducible stored-procedure calls.
+- Mandatory: read and follow `AGENTS_PAGE_STRUCTURE.md` for the `Pages/Modulo/` location of all new WebForms pages.
+- Mandatory: read and follow `AGENTS_WEBFORMS_PARTIAL_POSTBACKS.md` for the single master form, ScriptManager ownership, UpdatePanel usage, and partial-postback rules.
+- Mandatory: read and follow `AGENTS_JAVASCRIPT_INITIALIZATION.md` for per-element initialization flags, global event guards, and idempotent control setup after partial postbacks.
+- Mandatory: read and follow `AGENTS_CATALOG_STRUCTURE.md` for catalog titles, breadcrumbs, actions, filters, indicators, grids, quick-create modals, and detail pages.
+- Mandatory: read and follow `AGENTS_DOCUMENT_STORAGE.md` for document folders, client access validation, protected file retrieval, and GIS file naming.
+- Keep stored procedure names centralized.
+- Repositories must use `CommandType.StoredProcedure` and parameterized inputs/outputs.
+- Never concatenate raw user input into SQL.
+- The database default collation and general text columns must use `Modern_Spanish_CS_AS`.
+- Columns named `Codigo`, beginning with `Codigo`, or containing a real user login identifier such as `NombreUsuario`, `UsuarioPortal`, or `Acum_PortalUsuario` must use `Modern_Spanish_CI_AS`.
+- `AgenteUsuario` is browser/device metadata, not a login identifier, and must use the general `Modern_Spanish_CS_AS` collation.
+- Do not use `Modern_Spanish_CS_AI`.
+
+Recommended Web.config connection string pattern:
+
+```xml
+<connectionStrings>
+  <add name="DefaultConnection" connectionString="..." providerName="System.Data.SqlClient" />
+  <add name="SecurityConnection" connectionString="..." providerName="System.Data.SqlClient" />
+  <add name="ReportingConnection" connectionString="..." providerName="System.Data.SqlClient" />
+</connectionStrings>
+```
+
+---
+
+## Base page rules
+
+Normal pages should inherit from a C# base page.
+
+Preferred base class:
+
+```text
+App_Code/Infrastructure/ClsPaginaBase.cs
+```
+
+If the starter currently has `WebFormsPageBase.cs`, either:
+
+- rename it to `ClsPaginaBase.cs`, or
+- keep `WebFormsPageBase` and update this AGENTS.md/project rules consistently.
+
+Do not keep both base classes doing the same job.
+
+Base page responsibilities:
+
+- Validate authenticated session.
+- Expose current user from `IUserSessionContract`.
+- Provide helper methods for messages, redirects, and permissions.
+- Avoid database access.
+- Avoid page-specific business logic.

+# AGENTS_MANTENIMIENTO_PROYECTO.md
+
+These rules complement `AGENTS.md` and are mandatory whenever the task involves commands, security, error handling, user feedback, grids, PDF migration, file delivery, verification, or project evolution.
+
+## Command rules
+
+When giving commands for this project:
+
+- Prefer **PowerShell**, **Developer PowerShell**, or **Visual Studio Package Manager Console** commands.
+- Commands must be written in **one line**.
+- Do not use PowerShell line continuation with backticks.
+- Do not suggest `dotnet new webforms` because WebForms is not supported by the .NET CLI as an ASP.NET Core project.
+- If a WebForms project must be created from command line, use Visual Studio/MSBuild-compatible project files or create the project through Visual Studio using **ASP.NET Web Application (.NET Framework)**.
+- Target framework must be `.NET Framework 4.8` or `.NET Framework 4.8.1`.
+
+Recommended project creation path:
+
+```powershell
+mkdir "C:\Proyectos\Agua de hermosillo\Plataforma de Desarrolladores"
+```
+
+```powershell
+cd "C:\Proyectos\Agua de hermosillo\Plataforma de Desarrolladores"
+```
+
+Then create/open the WebForms project in Visual Studio 2022 as:
+
+```text
+ASP.NET Web Application (.NET Framework) → Web Forms → C# → .NET Framework 4.8/4.8.1
+```
+
+---
+
+## Security rules
+
+- Do not store passwords in code, comments, Web.config examples, or session.
+- Do not expose real connection strings in committed files.
+- Use dummy values in examples.
+- Use parameterized SQL.
+- Validate uploaded files by extension, MIME type, and size when uploads are later added.
+- Avoid writing raw exception details to the user in production.
+- Keep `customErrors mode="Off"` only for local development.
+
+---
+
+## Error handling rules
+
+Controlled outcomes and technical failures must use different logs.
+
+- `@ErrorTipo = 1`, SQL exceptions, timeouts, contract failures, and unexpected exceptions go to the main technical log.
+- `@ErrorTipo = 2` is a controlled warning. It must not be written to the main technical log.
+- Controlled warnings go to daily compact files under `~/log/controlled`.
+- Controlled log files retain only the current day and the previous two days. The retention is configured with `ControlledLogRetentionDays = 3`.
+- Explicit controlled throws must use `ControlledApplicationException`; do not classify arbitrary `Exception` or `InvalidOperationException` instances as controlled.
+- Controlled logs record date, source, procedure, URL, and friendly message, but omit full stack traces and replay SQL to remain compact.
+- A controlled exception must still return a friendly result to the page and must never be presented as an unexpected application failure.
+
+- Handle null session user cleanly and redirect to login.
+- Handle failed login with a friendly message.
+- Handle async postback errors through `ScriptManager.AsyncPostBackError` only if the handler exists.
+- Avoid infinite loading states in JavaScript controls.
+- For AJAX/server search controls, use client and server timeouts.
+- Recommended default search timeout: about 20 to 30 seconds unless the user asks otherwise.
+
+## Action availability and feedback rules
+
+- Do not disable a button or primary action only because a business prerequisite is missing, such as an unassigned client or an empty related catalog.
+- Keep the action available by default; when the user clicks it, validate the prerequisite and show a clear message explaining why the operation cannot continue and what must be done next.
+- Never leave a disabled action without an immediately visible explanation.
+- Before adding `Enabled="false"`, the HTML `disabled` attribute, or an equivalent disabled CSS/JavaScript state to a catalog or page action, ask the user whether disabling is acceptable or whether a message, modal, link, or other alternative should be used.
+- A transient disabled state used only while a request is being processed to prevent duplicate submissions is allowed, but the action must be restored when processing finishes.
+
+---
+
+## Grid display rules
+
+- Every new or modified `asp:GridView` must declare `GridLines="None"`.
+- Its `CssClass` must include the exact utility class `Widthall` so the grid uses the full available width.
+- Do not add `table-bordered` to a GridView. Existing visual classes such as `table`, `table-striped`, and `table-hover` may be retained when appropriate.
+- Keep GridView declarations and their columns expanded and indented according to the source code readability rules.
+- Detail-page navigation from a GridView or list must use `asp:HyperLink` or another real link with `NavigateUrl`; do not use `LinkButton`, `RowCommand`, or a postback only to open a detail page.
+- URL-building variables and helpers must describe the row entity, for example `cveFraccionamiento`, `fraccionamientoDetalleUrl`, or `GetFraccionamientoDetalleUrl`. Avoid generic names such as `id`, `itemUrl`, or `detailUrl` when the entity is known.
+
+---
+
+## PDF viewer migration rules
+
+If the PDF viewer is added to this project later:
+
+- Implement it in C#.
+- Prefer `App_Code/SigControls` for server controls.
+- Do not add VB files.
+- Do not use `/* */` comments in VB reference files; VB references must remain `.vb.txt` only.
+- Keep global PDF viewer CSS/JS references in bundles.
+- Do not register duplicate resources from the control and master at the same time.
+- Session or temp-folder PDF storage must be explicit and centralized.
+
+---
+
+## File delivery rules for this project
+
+When generating a single downloadable file:
+
+- If the file is `.js` or `.css` and it is not inside a ZIP, append `.txt` to the filename.
+- Example: `custom.js.txt`, `styles.css.txt`.
+- If the file is inside a ZIP, keep the real extension `.js` or `.css`.
+- For project-level delivery, prefer ZIP files.
+
+---
+
+## Current implementation checklist
+
+When modifying or regenerating the project, verify:
+
+- [ ] Project targets .NET Framework 4.8 or 4.8.1.
+- [ ] All new code is C#.
+- [ ] No active `.vb` files were added.
+- [ ] `Styles`, `Scripts`, and `Metronic` were copied as-is.
+- [ ] `BundleConfig.cs` contains only bundles rendered by master/login or required by WebForms AJAX.
+- [ ] `Site.master` owns the only main form.
+- [ ] Normal pages use `Site.master`.
+- [ ] Normal pages do not contain full HTML structure.
+- [ ] Login is the only standalone full HTML page.
+- [ ] User/session data comes from `IUserSessionContract`.
+- [ ] Login uses `IAuthContract`.
+- [ ] Menu comes from `IMenuContract`.
+- [ ] Master layout data comes from `IMasterPageContract`.
+- [ ] SQL connection helpers are centralized under `App_Code/Sql`.
+- [ ] Pages do not directly instantiate SQL connections.
+- [ ] Placeholder IDs are `H`, `C`, and `J`.
+- [ ] No hidden old search box was restored.
+- [ ] Actions button is preserved when present in the selected layout.
+- [ ] `Web.config` login URL matches the actual login page filename.
+- [ ] No duplicate `Login.aspx` / `LogIn.aspx` pages exist.
+- [ ] No OWIN startup error exists, or OWIN automatic startup is disabled.
+- [ ] No missing CodeDom provider error exists.
+
+---
+
+## Preferred next evolution
+
+After the starter works, the safest growth path is:
+
+1. Replace dummy login with SQL-backed `IAuthContract`.
+2. Replace dummy menu with SQL-backed `IMenuContract`.
+3. Add permission contract.
+4. Add base page authorization checks.
+5. Add reusable controls one by one.
+6. Add catalog search and UI helpers.
+7. Add PDF viewer only after the base shell is stable.
+
+Keep every new feature behind contracts so the WebForms UI remains thin and easier to migrate later if needed.

+# AGENTS_WEBFORMS_ESTRUCTURA.md
+
+These rules complement `AGENTS.md` and are mandatory whenever the task changes WebForms pages, the master page, login, session behavior, bundles, assets, configuration, controls, or the application shell.
+
+## Asset folder rules
+
+The following folders are legacy visual dependencies and must be copied as complete folders:
+
+```text
+Styles/
+Scripts/
+Metronic/
+```
+
+Do not replace Metronic with Bootstrap-only layout.
+Do not upgrade Metronic unless the user explicitly asks.
+Do not remove old scripts just because they look unused; only remove references from bundles when they are not used by the master/login flow.
+
+---
+
+## Bundle rules
+
+The project must implement only the bundle methods needed by the current `Site.master` and login page.
+
+Do not bring every old bundle method from the legacy project.
+Do not add unused bundle groups just because they existed before.
+Do not add duplicate bundle keys.
+Do not add empty bundle methods.
+
+Allowed current bundle keys are the ones actually rendered by master/login, especially:
+
+```text
+~/bundles/modernizr
+~/bundles/scripts
+~/bundles/highcharts
+~/Metronic/assets/global/scripts/JSV1
+~/Metronic/assets/global/css/cssV1
+```
+
+WebForms/AjaxControlToolkit support bundles are allowed only when referenced by `ScriptManager` or required by WebForms controls:
+
+```text
+~/bundles/jquery
+~/bundles/WebFormsJs
+~/bundles/MsAjaxJs
+~/Content/AjaxControlToolkit/Styles/Bundle
+```
+
+Rules:
+
+- If `Site.master` or `Login.aspx` does not render a bundle, do not add it.
+- If a bundle exists only for old pages not migrated yet, leave it out until the page needs it.
+- Prefer preserving original asset paths from `Styles`, `Scripts`, and `Metronic`.
+- Use `CssRewriteUrlTransform` for CSS bundles that reference fonts, images, or relative URLs.
+- Do not register CSS/JS from server controls when the style/script is global; use `BundleConfig` and the master page.
+
+---
+
+## WebForms page rules
+
+All normal `.aspx` pages must use `Site.master`, except the login page.
+
+Normal pages:
+
+- Must include `MasterPageFile="~/Site.master"`.
+- Must not include `<html>`, `<head>`, `<body>`, or `<form>`.
+- Must use `<asp:Content>` controls.
+- Should inherit from `ClsPaginaBase` or the current C# page base class.
+- Must not connect directly to SQL classes.
+- Must call contracts/services for data, authentication, permissions, catalogs, menus, and user context.
+
+Public registration exception:
+
+- `Pages/Security/RegistroCliente.aspx`, `RegistroPendiente.aspx` and `VerificarCorreo.aspx` may be standalone public pages with their own `form runat="server"`.
+- `RegistroCliente.aspx` keeps its two-step draft in encrypted ViewState and persists only after all client/company validations pass.
+- All persistence continues through contracts/services/repositories and stored procedures.
+
+Login page:
+
+- Is the only page allowed to have its own full HTML structure.
+- May inherit from `System.Web.UI.Page` or its own login base class.
+- Must not inherit from `ClsPaginaBase` if that base class requires an authenticated session.
+- Must use `IAuthContract` or the current auth contract.
+- Must create a dummy session until real authentication is implemented.
+- Must not hardcode real database login logic in `Login.aspx.cs`.
+
+Important naming rule:
+
+- Do not create both `Login.aspx` and `LogIn.aspx`.
+- If the starter already uses `LogIn.aspx`, keep that name and keep `Web.config` consistent.
+- If creating from scratch, prefer `Login.aspx`, but update `Web.config`, redirects, and links consistently.
+
+---
+
+## Master page rules
+
+`Site.master` owns the main HTML structure.
+
+Rules:
+
+- `Site.master` owns the only main `<form runat="server">`.
+- `Site.master` must keep the Metronic layout structure.
+- Keep the sidebar/header/page-content structure similar to the original Metronic project.
+- Do not restore the hidden search box from the old header.
+- Keep the actions button if it exists in the selected master layout.
+- Do not hardcode real user/menu database logic inside `Site.master.cs`.
+- User data must come from a contract/service.
+- Menu data must come from a contract/service.
+- Breadcrumb/title/layout data must come from a contract/service when dynamic.
+- Do not use `<title id="Titulo" runat="server">`.
+- Prefer `<title><%: Page.Title %></title>`.
+- If a generated starter currently uses a title literal, replace it with `Page.Title` unless there is a specific reason to keep the literal.
+
+Current preferred contracts:
+
+```text
+IAuthContract
+IUserSessionContract
+IMenuContract
+IMasterPageContract
+```
+
+If old names such as `IUserContextProvider` or `IMenuProvider` exist, migrate them to the current contract naming or create adapters. Do not keep two competing naming systems.
+
+---
+
+## ContentPlaceHolder rules
+
+`Site.master` must use short placeholder IDs.
+
+Preferred final placeholder IDs:
+
+```text
+H = page-specific head/CSS content
+C = main page content
+J = page-specific JavaScript
+```
+
+Example in `Site.master`:
+
+```aspx
+<asp:ContentPlaceHolder ID="H" runat="server" />
+<asp:ContentPlaceHolder ID="C" runat="server" />
+<asp:ContentPlaceHolder ID="J" runat="server" />
+```
+
+Example in a normal page:
+
+```aspx
+<asp:Content ID="ContentHead" ContentPlaceHolderID="H" runat="server">
+</asp:Content>
+
+<asp:Content ID="ContentMain" ContentPlaceHolderID="C" runat="server">
+</asp:Content>
+
+<asp:Content ID="ContentScripts" ContentPlaceHolderID="J" runat="server">
+</asp:Content>
+```
+
+If the generated starter currently has `HeadContent`, `MainContent`, or `ScriptsContent`, rename them to `H`, `C`, and `J` before adding more pages.
+
+Do not mix placeholder naming systems in the same project.
+
+---
+
+## WebForms tab and page-state rules
+
+- Register AjaxControlToolkit once in `Web.config` under `system.web/pages/controls` with the exact prefix `ajax`; do not add `<%@ Register ... %>` directives for it in individual pages.
+- AjaxControlToolkit controls must use the `ajax:` prefix, for example `ajax:TabContainer` and `ajax:TabPanel`; do not use `ajaxToolkit:` or another page-specific prefix.
+- Tabs in WebForms pages must use `ajax:TabContainer` and `ajax:TabPanel`; do not build page tabs with Bootstrap `nav-tabs`, custom hidden panels, or JavaScript-only tab switching.
+- Use the `ScriptManager` owned by `Site.master` and the existing AjaxControlToolkit resources. Do not add another `ScriptManager` or duplicate Toolkit scripts/styles.
+- Server-side page state such as current entity keys, selected child keys, editing mode, flags, and the active tab must be stored in typed `ViewState` properties when it must survive postback.
+- Do not add `asp:HiddenField` merely to preserve server-side state across postbacks. A hidden field is allowed only when client-side JavaScript must read or change the value.
+- Hidden-field values are client-controlled and must never be trusted for authorization or sensitive decisions; validate them again on the server when their use is unavoidable.
+- Keep ViewState values small and serializable. Do not store database connections, commands, readers, services, repositories, or unnecessarily large result sets in ViewState.
+- ViewState property and key names must identify the entity and purpose, for example `CveFraccionamientoActual` and `CveFraccionamientoEtapaActual`.
+- When a postback needs to recover related values from an already loaded catalog, store the typed serializable object list in a typed `ViewState` property and locate the selected object by its key.
+- Do not copy server-owned catalog or model values into HTML `data-*` attributes, CSS classes, hidden fields, or other client-controlled markup merely to recover them during a postback. Read them from the typed object list stored in `ViewState`.
+
+---
+
+## Login and session rules
+
+Authentication must go through a contract.
+
+Required flow:
+
+```text
+Login.aspx.cs
+  ↓
+IAuthContract
+  ↓
+DummyAuthContract now, real AuthService later
+  ↓
+IUserSessionContract
+  ↓
+Session user
+```
+
+Initial login may be dummy.
+
+Dummy session user should be safe and clearly fake, for example:
+
+```text
+UserId: 15
+CompanyId: 1
+RoleId: 1
+RoleName: Administrador
+CompanyName: Empresa Demo
+DisplayName: Usuario Demo
+```
+
+Rules:
+
+- Dummy login may accept any non-empty username and password during starter setup.
+- Mark dummy authentication clearly in code comments.
+- Do not mix real SQL authentication with dummy authentication in the same class.
+- When real login is implemented, create a new service such as `SqlAuthContract` or `AuthService`.
+- Do not store passwords in session.
+- Do not log raw passwords.
+- Use Forms Authentication if staying with classic WebForms auth.
+
+---
+
+## Global.asax rules
+
+`Global.asax` / `Global.asax.cs` should:
+
+- Register bundles through `BundleConfig.RegisterBundles(BundleTable.Bundles)`.
+- Configure basic application startup.
+- Avoid business logic.
+- Avoid direct database startup queries unless absolutely required.
+
+If OWIN is not used, prevent startup errors by adding this to `Web.config`:
+
+```xml
+<add key="owin:AutomaticAppStartup" value="false" />
+```
+
+Do not add OWIN packages unless the project actually needs OWIN.
+
+---
+
+## Web.config rules
+
+`Web.config` must stay compatible with ASP.NET WebForms on .NET Framework 4.8/4.8.1.
+
+Rules:
+
+- Use Forms Authentication unless a different auth system is explicitly requested.
+- Allow anonymous access only to the login page and required static assets.
+- Do not add ASP.NET Core middleware settings.
+- Do not add unsupported `.NET Core` config sections.
+- Do not add CodeDom provider entries unless the matching NuGet package is installed.
+- If this error appears: `No se pudo ubicar el tipo de proveedor CodeDom Microsoft.CodeDom.Providers.DotNetCompilerPlatform...`, either install the exact package version or remove/fix the `system.codedom` section.
+- Keep MIME mappings for fonts such as `.woff` and `.woff2` when Metronic requires them.
+
+---
+
+## OWIN rule
+
+If the application shows this error:
+
+```text
+No assembly found containing an OwinStartupAttribute
+```
+
+And the project does not use OWIN, add this in `appSettings`:
+
+```xml
+<add key="owin:AutomaticAppStartup" value="false" />
+```
+
+Do not create an empty OWIN startup class just to silence the error unless OWIN is actually required.
+
+---
+
+## Site.master rendering rules
+
+The master page should render bundles and scripts in this general order:
+
+Inside `<head>`:
+
+```aspx
+<%: Scripts.Render("~/bundles/modernizr") %>
+<%: Styles.Render("~/Content/AjaxControlToolkit/Styles/Bundle") %>
+<%: Styles.Render("~/Metronic/assets/global/css/cssV1") %>
+<asp:ContentPlaceHolder ID="H" runat="server" />
+```
+
+Inside `<form>` near the top:
+
+```aspx
+<asp:ScriptManager ID="TSM" runat="server" />
+<%: Scripts.Render("~/bundles/scripts") %>
+```
+
+Before closing `</form>`:
+
+```aspx
+<%: Scripts.Render("~/Metronic/assets/global/scripts/JSV1") %>
+<%: Scripts.Render("~/bundles/highcharts") %>
+<asp:ContentPlaceHolder ID="J" runat="server" />
+```
+
+Rules:
+
+- Do not render the same script twice.
+- Do not render JQuery twice.
+- Keep `ScriptManager` if AjaxControlToolkit, UpdatePanel, or WebForms AJAX is used.
+- Keep `TSM_AsyncPostBackError` only if implemented in code-behind.
+- Remove or implement any event handler referenced by markup.
+
+---
+
+## Header/menu rules
+
+The master header must preserve the selected Metronic layout.
+
+Rules:
+
+- Keep user dropdown.
+- Keep logout option.
+- Keep actions button when present.
+- Do not restore the hidden/old search box from legacy header.
+- Sidebar menu must be built from `IMenuContract`.
+- Do not build the menu from SQL inside `Site.master.cs`.
+- Menu items should use `MenuItemModel` or an equivalent model.
+- Encode text output when generating HTML menu strings.
+- Module visibility and page access are separate concerns: `Sis_Modulos.Visible` controls whether an item is shown in the menu, but it must not deny direct page access.
+- `PA_Sis_PaginaAccessCheck` must validate role assignment, `PuedeVer`, active state, and URL. It must not require `Sis_Modulos.Visible = 1`.
+
+---
+
+## Page title and breadcrumb rules
+
+Page title and breadcrumb should be handled consistently.
+
+Rules:
+
+- Use `Page.Title` for the browser title.
+- Use a master/layout model for visible page title and breadcrumb.
+- Do not hardcode global breadcrumb logic in every page.
+- Normal pages may set page title in `Page_Load` or via properties.
+
+Preferred model:
+
+```text
+MasterLayoutModel
+  PageTitle
+  Breadcrumbs
+  CurrentUser
+  MenuItems
+```
+
+---
+
+## JavaScript and CSS rules
+
+- Global scripts/styles must be registered in `BundleConfig` and rendered by master.
+- Page-specific scripts go in placeholder `J`.
+- Page-specific CSS/head content goes in placeholder `H`.
+- Do not inline large JavaScript blocks in `.aspx` unless page-specific and small.
+- Do not remove existing custom legacy files unless the user asks.
+- Fix null `addEventListener` errors by checking that the element exists before attaching events.
+- Avoid blocking Ctrl+V unless a specific feature requires it.
+
+---
+
+## User control rules
+
+If server controls are migrated:
+
+- Prefer C# classes under `App_Code/SigControls` when creating reusable server controls.
+- Do not mix WebForms `.ascx` user controls with App_Code server-control classes unless there is a clear reason.
+- Do not register global CSS/JS from the control when master bundles already include them.
+- Controls should expose properties/events and avoid direct SQL access.
+- Controls should call contracts/services when they need data.
+
+---
+
+## Home page rules
+
+Use only one active home page convention.
+
+For local development, the canonical home URL is:
+
+```text
+http://localhost:52706/Inicio.aspx
+```
+
+The application root must be equivalent and redirect explicitly to that page:
+
+```text
+http://localhost:52706/  ->  http://localhost:52706/Inicio.aspx
+```
+
+Keep the root redirect and the `Inicio.aspx` default document consistent. Do not introduce another startup page.
+
+Allowed options:
+
+```text
+Default.aspx
+Inicio.aspx
+```
+
+Rules:
+
+- Do not keep both as competing entry pages.
+- If using `Inicio.aspx`, redirect `Default.aspx` to `Inicio.aspx` or update Forms Authentication default URL.
+- If using `Default.aspx`, keep Web.config and menu links pointing to `Default.aspx`.
+- The home page must use `Site.master`.
