+# Pitchfork Architecture and Core Properties
+
+Pitchfork is a highly consistent, modular, and secure web application and command-line framework written in Go. It acts as the foundation for [Trident](https://trident.li) and other identity, group, and wiki management systems.
+
+This document describes the core properties, design patterns, and architecture of the Pitchfork framework.
+
+---
+
+## 1. System Architecture and Directory Structure
+
+The codebase is organized into clear, single-responsibility domains:
+
+*   **`cmd/`**: Application entry points.
+    *   `cmd/server/`: Web server daemon (`server.go`).
+    *   `cmd/cli/`: Command-line client (`cli.go`).
+    *   `cmd/setup/`: System initialization, database schema creation, migrations, and administrative tools (adds first user, resets passwords, sudo testing).
+    *   `cmd/wikiexport/`: Command utility to bulk export wiki structures.
+*   **`lib/`**: Core business logic, framework, ORM, state handling, and domain modules.
+    *   `app.go` & `cfg.go`: Global state and configuration (JSON-based parsing with comments stripping).
+    *   `ctx.go`: Context definition (`PfCtx`) containing the request session, transactional DB scope, client IP, language translation, and scopes.
+    *   `db.go`: Postgres driver wrapper enforcing auditing, connection pooling, and raw SQL transaction handling.
+    *   `struct.go`: Proprietary reflection-based Object-Relational Mapping (ORM) engine.
+    *   `system.go`: General system configuration (stored in DB) and auditing extraction.
+    *   `user.go`, `group.go`, `ml.go`: Core domain models (users, groups, mailing lists, 2FA, emails, wiki pages).
+    *   `iptrk.go`: Goroutine-driven, database-backed IP rate tracking and lockout engine.
+*   **`ui/`**: Web front-end.
+    *   `ui.go`: Extended context (`PfUI`) adding HTTP parsing, cookie management, response writing, headers, and page templates rendering.
+    *   `form.go`: Reflection-based HTML forms compiler.
+    *   `root.go`: Main HTTP handler and tree-based path router.
+*   **`share/`**: Static assets and resources.
+    *   `share/dbschemas/`: Incremental PostgreSQL schema migrations (`DB_0.psql` to `DB_20.psql`).
+    *   `share/languages/`: Localization translations.
+    *   `share/templates/`: HTML templates.
+
+---
+
+## 2. The Unified Execution Engine Design Pattern
+
+One of Pitchfork's most powerful architectural properties is its **Unified Web & CLI Execution Engine**.
+
+Instead of duplicating business logic between CLI flags/commands and Web UI routes, Pitchfork routes **all** user actions through a single command-tree system:
+
+```mermaid
+graph TD
+    CLI[CLI Application] -->|Parses line| CmdParser[lib.Ctx.Cmd]
+    WebForm[Web UI POST Form] -->|Parses form keys| FormHandler[ui.HandleFormS]
+    FormHandler -->|Constructs equivalent CLI args| CmdParser
+    CmdParser -->|Permission check| CheckPerms[lib.Ctx.CheckPerms]
+    CheckPerms -->|Allowed| Exec[Command Function: lib.PfFunc]
+```
+
+### Mechanics
+1. **Command Definition**: Business actions are defined as `PfMEntry` items, specifying parameter counts, argument types, permission requirements, and the implementation `PfFunc` callback:
+   ```go
+   type PfFunc func(ctx PfCtx, args []string) error
+   ```
+2. **Web Form Binding**: When a web form is submitted via POST, `ui.HandleFormS` automatically:
+   * Evaluates struct tags to list valid updateable fields.
+   * Matches keys present in the form submission.
+   * Synthesizes a space-separated CLI command array (e.g., `[]string{"user", "set", "email", "user@example.com"}`).
+   * Dispatches the synthesized command directly into `ctx.Cmd()`.
+3. **Benefits**:
+   * **100% Consistency**: The CLI and Web UI are guaranteed to behave identically.
+   * **Zero Duplication**: Developers write a change or validation step once, and it automatically supports both terminal scripts and web interfaces.
+   * **Auditability**: Because all writes resolve to commands, the system can audit operations uniformly.
+
+---
+
+## 3. Context & Session State Lifecycle (`PfCtx` & `PfUI`)
+
+Pitchfork maintains request isolation using an explicit context passing pattern:
+
+*   **`PfCtx` Interface**: Extends across all operations. It carries:
+    *   `abort <-chan bool`: Client cancellation channel.
+    *   `user PfUser`: Currently authenticated caller.
+    *   `db_Tx *Tx`: Transaction boundary for the request.
+    *   `sel_user`, `sel_group`: Target scopes of the command (who or what group is being acted upon).
+    *   `client_ip`: Fully resolved client IP.
+    *   `tfunc`: Current localization translation hook.
+*   **`PfUI` Interface**: Extends `PfCtx` with Web-only attributes (`http.Request`, `http.ResponseWriter`, cookies, templates metadata).
+*   **Impersonation (`Become`)**: Administrative commands or test routines can swap the execution identity inside the context using `ctx.Become(targetUser)`.
+
+---
+
+## 4. Strict Database Auditing & Postgres Wrapper
+
+To meet operational compliance standards, the database wrapper `PfDB` implements **Mandatory Auditing Constraints**:
+
+1. **Explicit Audit Messages**: All SQL writes (inserts, updates, deletes) executed via `DB.Exec` or `DB.QueryRowA` **must** supply a non-empty `audittxt` string. Running a non-`SELECT` query without an audit message triggers a runtime `panic`.
+2. **Transactional Integrity**: If a write is made outside an explicit context transaction, `PfDB` opens a short local transaction, executes the statement, inserts the audit entry into the `audit_history` table, and commits or rolls back atomically.
+3. **Audit Ingestion**: The audit log captures the acting user (`member`), target user (`username`), target group (`trustgroup`), exact formatted SQL action text, and the remote client IP.
+
+---
+
+## 5. Reflection-Based ORM and Forms Compilation
+
+To reduce boilerplate, Pitchfork avoids third-party heavyweight ORM libraries and instead utilizes two custom Go-reflection engines:
+
+### Dynamic SQL ORM (`lib/struct.go`)
+Pitchfork maps Go structs directly to Postgres tables using struct tags:
+*   `pfcol`: Specifies the database column name.
+*   `pftable`: Specifies the database table name.
+*   `coalesce`: Specifies the default value to return for nullable rows.
+
+`StructFetchFields` reads struct tags to automatically construct SQL `SELECT` projection clauses and yields matching scanner destination pointers. `StructFetchStore` maps completed SQL row scans back into the instantiated struct fields.
+
+### Reflective Forms Compiler (`ui/form.go`)
+Web forms are rendered directly from database-backed Go structs using the custom `pfform` template function:
+*   Reads field datatypes (e.g., `string`, `bool`, `int`, `struct`).
+*   Inspects validation constraints such as `min`, `max`, and custom config regex patterns (e.g., `username_regexp`).
+*   Enforces structural access rules:
+    *   `isvisible`: Points to a struct method that decides if the user has permissions to see the field.
+    *   `readonly`: Compiles inputs into static, un-editable text fields accompanied by hidden inputs to keep POST requests intact.
+
+---
+
+## 6. Security and Robustness Measures
+
+Pitchfork implements multiple defensive programming guards:
+
+*   **CSRF Protection**: `ui/ui.go` strictly validates a cryptographic hidden value (`CSRF_TOKENNAME` or `X-XSRF-TOKEN` header) for all POST form requests.
+*   **Proxy-Safe IP Resolution (XFF)**: `ParseClientIP` walks the `X-Forwarded-For` chain from right-to-left to locate the first untrusted IP outside of the configured reverse proxy CIDRs (`xff_trusted_cidr`). This prevents header-injection spoofing of client IP addresses.
+*   **SysAdmin IP Restrictions (SAR)**: Even if a user's account has the `SysAdmin` flag enabled, administrative actions are rejected unless the resolved client IP falls within the space-separated CIDR block specified in `SARestrict` (excluding localhost/loopback).
+*   **IP Lockout Engine (`iptrk`)**: Failed logins or invalid CSRF requests increment a database-backed IP tracking count. When this threshold (`IPtrk_Max`) is breached, requests are locked out. Updates are processed asynchronously via a dedicated background Goroutine to prevent thread congestion during flood attacks.
+*   **Stateless JWT Sessions**: Signed private/public JWT tokens track authenticated sessions. To mitigate token leaks, Pitchfork supports token invalidation via a `jwt_invalid` table.
+*   **HTML Sanitization**: Utilizes `bluemonday` to cleanse dynamic HTML inputs before they are rendered on Wiki templates.
+
+---
+
+## 7. Multi-Namespace Wiki System
+
+The built-in Wiki system supports dynamic, multi-tenant namespace routing:
+*   **Data model**: Wiki paths are mapped in `wiki_namespace` while full histories are kept under `wiki_page_rev`.
+*   **Mount points (`Wiki_ModOpts`)**: Wikis can be mounted under different paths (e.g., a global wiki at `/system/wiki` or a group-specific wiki at `/group/<groupname>/wiki`).
+*   **Search & Revisions**: Includes built-in search projecting matching snippets and standard revision list retrieval.
+*   **Markup**: Uses `blackfriday` to translate markdown to structured, safe HTML bodies alongside automatically synthesized tables of contents (`html_toc`).

+# Pitchfork Codebase Modernization & Security Review Plan
+
+This document outlines a phased plan to modernize the Pitchfork framework, improve its testability and coverage, and conduct a thorough security review.
+
+---
+
+## Executive Summary
+
+Pitchfork is a modular and secure web application and CLI framework written in Go. While it has a solid architectural foundation (Unified Execution Engine, strict database auditing, proxy-safe IP resolution), it currently faces several technical debt challenges:
+*   **Outdated Go Version:** Currently using Go 1.18 (released in early 2022).
+*   **Outdated Dependencies:** Many third-party libraries are outdated or deprecated.
+*   **High Barrier to Testing:** Existing tests are integration tests requiring an active PostgreSQL database and specific environment variables, resulting in 0% actual unit test coverage during standard `go test` runs.
+*   **Custom Components:** Relying on custom reflection-based ORM and Forms compilers which are hard to maintain and audit.
+
+This plan proposes a **5-Phase approach** to address these issues, targeting modern Go standards, near 100% test coverage for critical components, and a robust security posture.
+
+---
+
+## Phase 1: Assessment & Local Test Environment Setup [COMPLETE]
+
+**Goal:** Enable reliable, repeatable execution of existing integration tests locally and in CI.
+
+### Actions:
+1.  **Create a Containerized Test Environment:** (Completed)
+    *   Develop a `docker-compose.yml` file to spin up a local PostgreSQL database.
+    *   Define a Dockerfile for Pitchfork that can run migrations and execute tests.
+2.  **Document and Automate Test Execution:** (Completed)
+    *   Create a script (e.g., `scripts/run_tests.sh`) that automatically sets up the database, applies schema migrations (`share/dbschemas/`), sets required environment variables (`PITCHFORK_TOOLNAME`, `PITCHFORK_CONFROOT`), and runs the tests.
+    *   Fix the early-exit behavior in `lib/test/helpers.go` so that tests fail visibly if the environment is misconfigured, rather than silently passing with 0% coverage.
+3.  **Baseline Coverage Assessment:** (Completed)
+    *   Run the existing tests in the containerized environment to get a true baseline coverage report.
+
+---
+
+## Phase 2: Go & Dependency Modernization
+
+**Goal:** Upgrade the core Go runtime and modernize third-party dependencies.
+
+### Actions:
+1.  **Upgrade Go Version:**
+    *   Upgrade `go.mod` to **Go 1.21** (or **1.22**).
+    *   Update `debian/control` to reflect the newer Go version requirement for packaging.
+2.  **Update Key Dependencies:**
+    *   `github.com/golang-jwt/jwt`: Upgrade to `github.com/golang-jwt/jwt/v5` (or v4) as v3 is deprecated and has known security issues.
+    *   `github.com/russross/blackfriday`: Upgrade to v2 or migrate to `github.com/yuin/goldmark` (the standard markdown parser in modern Go).
+    *   `github.com/nicksnyder/go-i18n`: Upgrade to v2 for better localization support.
+    *   `github.com/pborman/uuid`: Replace with the more standard `github.com/google/uuid`.
+3.  **Refactor for Modern Go Features:**
+    *   **Structured Logging (`slog`):** Evaluate replacing custom logging in `lib/db.go` and `lib/misc.go` with the standard library's `charcoal/slog` (available in Go 1.21+) for structured, level-based logging.
+    *   **Generics:** Explore using generics to simplify the custom ORM (`lib/struct.go`) or other utility functions.
+
+---
+
+## Phase 3: Test Suite Refactoring & Decoupling (Unit Testing)
+
+**Goal:** Decouple business logic from the database to allow fast, hermetic unit tests, aiming for high coverage.
+
+### Actions:
+1.  **Introduce Database Mocking:**
+    *   Integrate `github.com/DATA-DOG/go-sqlmock` into the test suite.
+    *   Refactor `PfDB` connection logic to allow injecting a mocked `*sql.DB` connection during tests.
+2.  **Refactor to Interfaces (Dependency Injection):**
+    *   Define interfaces for core services (e.g., User Service, Group Service, Wiki Service).
+    *   Modify the handlers and commands to accept these interfaces rather than relying strictly on global state. This allows mocking services in tests.
+3.  **Write Comprehensive Unit Tests:**
+    *   **Priority 1 (Core Logic):** Write unit tests with mocked DB for `lib/user.go`, `lib/group.go`, `lib/jwt.go`, and `lib/iptrk.go`.
+    *   **Priority 2 (Custom Framework):** Write tests for the reflection-based ORM (`lib/struct.go`) and forms compiler (`ui/form.go`) with various edge cases.
+    *   **Priority 3 (UI Handlers):** Use `net/http/httptest` to test HTTP handlers in `ui/root.go` and `ui/form.go` with simulated requests.
+4.  **Target Coverage:**
+    *   Aim for **>90% coverage** on core business logic (`lib/`) and security-critical components (`lib/jwt.go`, `lib/user_2fa.go`, `lib/iptrk.go`).
+
+---
+
+## Phase 4: CI/CD Pipeline & Code Quality
+
+**Goal:** Automate testing, linting, and coverage reporting to prevent regression.
+
+### Actions:
+1.  **GitHub Actions Integration:**
+    *   Create `.github/workflows/test.yml` to run on every Pull Request and commit to `main`.
+    *   **Job 1 (Linting):** Run `golangci-lint` to enforce style, check for common bugs, and ensure formatting.
+    *   **Job 2 (Unit Tests):** Run unit tests (using mocks) without needing a database.
+    *   **Job 3 (Integration Tests):** Spin up a Postgres service container, run migrations, and execute database-dependent integration tests.
+2.  **Coverage Reporting:**
+    *   Integrate a coverage reporting tool (e.g., Codecov or GitHub Actions artifacts) to track coverage over time and block PRs that decrease coverage.
+
+---
+
+## Phase 5: Security Review & Hardening
+
+**Goal:** Conduct a deep, structured security review and establish a vulnerability management process.
+
+### Threat Modeling & Review Areas:
+1.  **Custom ORM & SQL Injection:**
+    *   *Risk:* Dynamic SQL generation in `lib/struct.go` and query helper methods (`Q_AddWhere`, `Q_AddArg`) in `lib/db.go`.
+    *   *Action:* Audit how queries are constructed. Ensure all user input is strictly parameterized and no raw string concatenation of user input occurs.
+2.  **Authentication & Session Management:**
+    *   *Risk:* JWT token leakage, signature bypass, or weak key usage.
+    *   *Action:* Review JWT signing and verification logic in `lib/jwt.go`. Verify token invalidation mechanism (`jwt_invalid` table) works under load. Ensure keys are managed securely and not hardcoded.
+3.  **Impersonation (`Become`):**
+    *   *Risk:* Unauthorized users triggering the `Become` function to escalate privileges.
+    *   *Action:* Thoroughly audit all usages of `ctx.Become`. Enforce that only validated administrators from trusted IPs (SAR) can trigger it.
+4.  **Proxy-Safe IP Resolution (XFF):**
+    *   *Risk:* IP spoofing leading to SAR bypass or IP lockout evasion.
+    *   *Action:* Audit `ParseClientIP` in `lib/misc.go` against various proxy configurations (multiple proxies, spoofed headers).
+5.  **Input Validation & XSS:**
+    *   *Risk:* XSS in Wiki pages or custom forms.
+    *   *Action:* Verify `bluemonday` HTML sanitization is applied consistently to all user-supplied markdown/HTML before rendering. Audit the reflection-based forms validation constraints.
+6.  **CSRF Protection:**
+    *   *Risk:* CSRF bypass on state-changing POST requests.
+    *   *Action:* Verify CSRF token validation in `ui/ui.go` is robust and cannot be bypassed (e.g., by changing content type or omitting the token).
+
+### Security Tooling & Finding Management:
+*   **Static Application Security Testing (SAST):** Integrate `gosec` into the linting phase to automatically scan for common Go security issues.
+*   **Dependency Scanning:** Integrate `govulncheck` into the CI pipeline to detect known vulnerabilities in dependencies.
+*   **Finding Management Plan:**
+    *   **Triage:** Classify findings using CVSS (Common Vulnerability Scoring System).
+    *   **Remediation SLA:** Establish timelines for fixing vulnerabilities (e.g., Critical: 7 days, High: 30 days, Medium: 90 days).
+    *   **Regression Testing:** For every security fix, write a dedicated test case to prevent reintroduction.
