+## CRITICAL: Lint Rules Are Sacred and Immutable
+
+**ABSOLUTE PROHIBITION**: You are **FORBIDDEN** from modifying, disabling, or bypassing any lint rules, ESLint configurations, TypeScript compiler settings, or any other code quality enforcement mechanisms in this repository.
+
+## Non-Negotiable Principles
+
+### 1. Rules Must NEVER Be Changed
+
+- **NO** adding `// eslint-disable` comments
+- **NO** adding `// @ts-ignore` or `// @ts-expect-error` comments
+- **NO** modifying `.eslintrc`, `eslint.config.js`, or any ESLint configuration files
+- **NO** modifying `tsconfig.json` compiler options to silence errors
+- **NO** modifying `biome.json`, `prettier.config.js`, `.oxlintrc`, or any formatter settings
+- **NO** adding files to `.eslintignore` or exclude patterns
+- **NO** downgrading errors to warnings or warnings to off
+- **NO** adjusting rule severity or options
+
+### 2. Fix the Root Cause, Not the Symptom
+
+When encountering a lint error or type error:
+
+1. **Attempt 1-10**: Fix the underlying code issue that violates the rule
+   - Refactor the code to comply with the rule
+   - Restructure the logic to avoid the violation
+   - Use proper types and patterns that satisfy the linter
+   - Redesign the approach entirely if needed
+   - Consider alternative implementations
+   - Review similar patterns in the codebase for guidance
+   - Consult documentation for the library/framework being used
+   - Try multiple different architectural approaches
+   - Explore edge cases and alternative solutions
+   - Exhaust ALL possible code-level fixes
+
+2. **After 10+ Genuine Attempts**: If you have exhausted ALL reasonable code fixes and the error persists:
+   - **STOP** and **ASK THE USER** for guidance
+   - Present the specific rule violation
+   - Explain what you've tried (all 10+ attempts)
+   - Ask if there's a pattern you're missing or if an exception is warranted
+   - **NEVER** make the decision to disable or modify rules yourself
+
+### 3. Why Rules Exist
+
+- Lint rules enforce consistency across the codebase
+- They prevent bugs and anti-patterns
+- They represent team decisions and conventions
+- They ensure code quality and maintainability
+- They are project-specific and carefully chosen
+
+### 4. Common Scenarios and Correct Responses
+
+#### Scenario: "Unused variable" error
+- ❌ WRONG: Add `// eslint-disable-next-line no-unused-vars`
+- ✅ RIGHT: Remove the unused variable or use it properly
+
+#### Scenario: "any type" error
+- ❌ WRONG: Add `// @ts-ignore` or change to `unknown` just to silence
+- ✅ RIGHT: Define proper types that accurately represent the data
+
+#### Scenario: "Missing dependency in useEffect" warning
+- ❌ WRONG: Add `// eslint-disable-next-line react-hooks/exhaustive-deps`
+- ✅ RIGHT: Add the missing dependency or restructure to avoid the issue
+
+#### Scenario: "Type errors in third-party library"
+- ❌ WRONG: Use `@ts-expect-error` or cast to `any`
+- ✅ RIGHT: Install proper type definitions, create a typed wrapper, or use proper type assertions
+
+#### Scenario: "Complexity too high" error
+- ❌ WRONG: Disable the complexity rule
+- ✅ RIGHT: Refactor the function into smaller, simpler functions
+
+### 5. Enforcement Priority
+
+Lint rules have **MAXIMUM PRIORITY**. They outrank:
+- Personal coding preferences
+- Convenience
+- Speed of implementation
+- Desire to "just make it work"
+
+### 6. Remember
+
+**You are here to serve the repository's conventions, not to modify them.**
+
+If you find yourself thinking "it would be easier to just disable this rule," that is **EXACTLY** when you must **NOT** do it.
+
+## Summary
+
+1. ❌ NEVER disable, ignore, or modify lint rules
+2. ✅ ALWAYS fix the code to comply with rules
+3. ✅ Try 10+ different approaches to fix the root issue
+4. ✅ ASK THE USER if all code-level fixes fail
+5. ❌ NEVER act autonomously on rule modifications
+
+**These are not guidelines. These are absolute requirements.**

+## Bun Guidelines
+
+**CRITICAL**: Do not assume you know full Bun APIs. For **ANY** Bun API you use, confirm them by using `bun-docs` MCP tools.
+
+Default to using Bun instead of Node.js.
+
+- Use `bun <file>` instead of `node <file>` or `ts-node <file>`
+- Use `bun test` instead of `jest` or `vitest`
+- Use `bun build <file.html|file.ts|file.css>` instead of `webpack` or `esbuild`
+- Use `bun install` instead of `npm install` or `yarn install` or `pnpm install`
+- Use `bun run <script>` instead of `npm run <script>` or `yarn run <script>` or `pnpm run <script>`
+- Use `bunx <package> <command>` instead of `npx <package> <command>`
+- Bun automatically loads .env, so don't use dotenv.
+
+### APIs
+
+- `Bun.serve()` supports WebSockets, HTTPS, and routes. Don't use `express`.
+- `bun:sqlite` for SQLite. Don't use `better-sqlite3`.
+- `Bun.redis` for Redis. Don't use `ioredis`.
+- `Bun.sql` for Postgres. Don't use `pg` or `postgres.js`.
+- `WebSocket` is built-in. Don't use `ws`.
+- Prefer `Bun.file` over `node:fs`'s readFile/writeFile
+- Bun.$`ls` instead of execa.
+
+### Testing
+
+#### Quick Start
+- Run tests: `bun test`
+- Write tests in `tests/` folder
+
+#### Test Structure
+- Use `describe` blocks to group related tests
+- Use `test` for individual test cases
+- Use `beforeEach`/`afterEach` for setup/teardown
+
+#### Assertions
+- Import: `import { test, expect, describe, beforeEach, afterEach, mock } from "bun:test";`
+- Common: `expect(value).toBe(expected)`, `expect(fn).rejects.toThrow()`
+- Async: `await expect(asyncFn()).resolves.toBe(expected)`
+
+#### Mocking
+- Mock functions: `mock(fn)`
+- Mock globals: `global.fetch = mock(...)`
+- Restore mocks in `afterEach` or `finally`
+
+#### Best Practices
+- Mock external APIs (fetch, file I/O)
+- Test error cases and edge conditions
+- Use descriptive test names
+- Clean up resources in `afterEach`
+
+For more information, read the Bun API docs in `node_modules/bun-types/docs/**.mdx`.

+## Zod Guidelines
+
+### Schema Definition
+- Define all schemas in `src/types.ts`
+- Use `z.object()` for objects, `z.array()` for arrays
+- Mark optional fields with `.optional()`
+- Create generic schemas for reusable structures
+
+### Type Inference
+- Always infer types from schemas: `export type Foo = z.infer<typeof FooSchema>`
+
+### Validation
+- Use `.parse()` to validate API responses
+- Only validate successful responses (`retcode === RESPONSE_CODES.SUCCESS`)
+- Return unvalidated responses for error cases
+
+### Patterns
+- Follow existing schema naming: `FooSchema` for schemas, `Foo` for types
+- Use `ZZZResponseSchema(dataSchema)` for API responses

+# Production Testing Doctrine
+_Project-Agnostic Engineering Standard_
+
+---
+
+# 1. Purpose of Testing
+
+Testing exists to:
+
+- Prevent regressions
+- Protect critical business behavior
+- Enforce invariants
+- Guard boundaries
+- Provide safe refactoring
+- Reduce production incidents
+
+Testing does not exist to:
+
+- Increase coverage numbers
+- Satisfy tooling requirements
+- Mirror implementation line‑by‑line
+- Create a false sense of security
+
+If a test does not reduce real-world risk, it should not exist.
+
+---
+
+# 2. Core Principles
+
+---
+
+## 2.1 Determinism Is Non-Negotiable
+
+A test must:
+
+- Produce the same result every run
+- Not depend on execution order
+- Not depend on global state
+- Not depend on wall-clock time
+- Not depend on external networks
+- Not depend on randomness (unless seeded)
+
+A flaky test is worse than no test.
+
+If a test fails intermittently:
+- Fix it immediately
+- Or delete it
+
+There is no third option.
+
+---
+
+## 2.2 Isolation of Behavior
+
+Tests should verify behavior in isolation from unrelated systems.
+
+The smaller the scope of the test, the more reliable and faster it is.
+
+We separate:
+
+- Pure logic
+- System interactions
+- External integrations
+- Full-system behavior
+
+Confusing these layers results in slow, fragile suites.
+
+---
+
+## 2.3 Risk-Based Testing
+
+Testing effort should scale with risk.
+
+High-risk areas:
+- Financial logic
+- Security and access control
+- Data mutation
+- Distributed coordination
+- Concurrency
+- Migration and transformation logic
+
+Low-risk areas:
+- Static rendering
+- Formatting helpers
+- Simple data mapping
+
+Testing must prioritize business-critical systems.
+
+---
+
+## 2.4 Tests Are Part of the System
+
+Tests must follow the same standards as production code:
+
+- Clean structure
+- Clear naming
+- Maintainable
+- Reviewed in PRs
+- Refactored when necessary
+
+Test code quality reflects engineering quality.
+
+---
+
+# 3. Testing Layers (Architecture-Neutral)
+
+These layers apply universally.
+
+---
+
+# 3.1 Unit Tests (Logic Layer)
+
+Definition:
+Tests that validate pure behavior without system dependencies.
+
+Must:
+
+- Run fast
+- Avoid I/O
+- Avoid network
+- Avoid persistent state
+- Avoid framework bootstrapping
+
+Should test:
+
+- Business rules
+- Domain invariants
+- Edge cases
+- Validation
+- Transformation logic
+
+Reasoning:
+If logic cannot be tested without infrastructure, it is coupled too tightly.
+
+---
+
+# 3.2 Integration Tests (System Boundary Layer)
+
+Definition:
+Tests that validate interactions between internal components.
+
+May include:
+
+- Datastores
+- Filesystems
+- Queues
+- Caches
+- Framework wiring
+- Service boundaries
+
+Must:
+
+- Use real internal components
+- Reset state between runs
+- Avoid real external services
+
+Reasoning:
+Most production bugs occur at boundaries, not in pure functions.
+
+---
+
+# 3.3 External Integration Tests
+
+Definition:
+Tests that validate interaction with third-party systems.
+
+Policy:
+
+- Prefer mocking or simulation
+- Use sandbox environments only when necessary
+- Never depend on live production services
+
+Reasoning:
+External systems are outside your control and introduce nondeterminism.
+
+---
+
+# 3.4 End-to-End Tests (System-Level)
+
+Definition:
+Tests that validate complete workflows from entry to outcome.
+
+Must:
+
+- Cover only critical flows
+- Be minimal in number
+- Run in isolated environments
+- Avoid unnecessary duplication of lower-level tests
+
+End-to-end tests are expensive and fragile. Use them surgically.
+
+---
+
+# 4. State Management Policy
+
+---
+
+## 4.1 No Shared State Between Tests
+
+Every test must assume a blank environment.
+
+Options:
+
+- Fresh environment per test
+- Transaction rollback
+- Full reset between runs
+- Isolated test containers
+
+No test may depend on side effects from another test.
+
+---
+
+## 4.2 Reproducible Environments
+
+Tests must run consistently:
+
+- Locally
+- In CI
+- In parallel
+- Across operating systems (if supported)
+
+Environment drift is unacceptable.
+
+---
+
+# 5. Mocking Policy
+
+---
+
+## 5.1 Mock External Systems
+
+Mock:
+
+- Third-party APIs
+- Payment providers
+- Email systems
+- External storage
+- Network services outside system boundary
+
+Reasoning:
+You do not control them.
+
+---
+
+## 5.2 Do Not Mock Core Logic
+
+Never mock:
+
+- Business rules
+- Authorization checks
+- Data validation
+- Domain logic
+
+Mocking internal logic invalidates the test.
+
+---
+
+## 5.3 Avoid Over-Mocking
+
+Over-mocking:
+
+- Couples tests to implementation
+- Breaks refactoring
+- Creates fragile tests
+
+Mock only what crosses system boundaries.
+
+---
+
+# 6. Error & Edge Case Policy
+
+Every public interface must have tests for:
+
+- Valid input
+- Invalid input
+- Unauthorized or restricted access (if applicable)
+- Boundary values
+- Failure paths
+- Concurrency conflicts (if applicable)
+
+Most real-world failures happen outside happy paths.
+
+---
+
+# 7. Security Testing Doctrine
+
+All systems must test:
+
+- Access control enforcement
+- Privilege boundaries
+- Input validation
+- Injection resistance (where applicable)
+- Role escalation prevention
+
+Security-sensitive logic must have near-complete coverage.
+
+---
+
+# 8. Concurrency & Race Conditions
+
+If the system involves:
+
+- Multi-threading
+- Distributed nodes
+- Async processing
+- Queues
+- Parallel writes
+
+Then tests must include:
+
+- Concurrent execution scenarios
+- Conflict handling
+- Idempotency verification
+- Retry logic behavior
+
+These bugs rarely appear in simple test cases.
+
+---
+
+# 9. Migration & Data Evolution
+
+If the system stores data over time:
+
+- Schema migrations must be tested
+- Data transformation must be verified
+- Backward compatibility must be validated
+- Downgrade scenarios (if supported) must be considered
+
+Silent data corruption is catastrophic.
+
+---
+
+# 10. CI Enforcement
+
+Tests must run automatically:
+
+- On every pull request
+- On main branch
+- Before release
+
+CI must:
+
+- Fail fast
+- Prevent merges on failure
+- Run in clean environments
+- Be reproducible
+
+If tests only run locally, they are not part of the system.
+
+---
+
+# 11. Coverage Philosophy
+
+Coverage is a diagnostic tool, not a goal.
+
+Required:
+
+- High coverage on business-critical modules
+- Full coverage on security boundaries
+- Full coverage on financial logic
+
+Optional:
+
+- High coverage on trivial UI or formatting
+
+100% coverage does not imply correctness.
+Low coverage in critical areas is unacceptable.
+
+---
+
+# 12. Performance of the Test Suite
+
+The test suite must:
+
+- Run quickly enough to encourage frequent execution
+- Support parallelization
+- Avoid arbitrary sleeps
+- Avoid unnecessary bootstrapping
+
+Slow tests reduce engineering velocity and discourage use.
+
+---
+
+# 13. Red Flags (Immediate Rejection)
+
+- Tests that sometimes fail
+- Tests that depend on execution order
+- Snapshot abuse
+- Arbitrary timeouts to “fix” flakiness
+- Global mutable state
+- Randomized data without seed
+- Testing implementation details instead of behavior
+- Excessive E2E replacing proper layering
+- Mocking core domain logic
+- Tests that assert only truthy values
+
+---
+
+# 14. Refactoring Policy
+
+Tests must enable refactoring.
+
+If changing internal structure breaks many tests without changing behavior:
+
+- The tests are coupled incorrectly.
+
+Behavioral contracts should remain stable under refactor.
+
+---
+
+# 15. Production Observability Complements Testing
+
+Testing does not replace:
+
+- Logging
+- Monitoring
+- Alerting
+- Metrics
+- Tracing
+
+Tests prevent known failures.
+Observability detects unknown ones.
+
+Both are required.
+
+---
+
+# 16. The Engineering Mindset
+
+Before writing any test, ask:
+
+1. What failure would hurt the business most?
+2. What invariant must never break?
+3. What boundary is being crossed?
+4. What assumptions are being made?
+5. Can this test fail nondeterministically?
+6. Is this testing behavior or implementation?
+
+If the test does not meaningfully reduce risk, reconsider it.
+
+---
+
+# 17. Definition of Production-Grade Testing
+
+A system with production-grade testing:
+
+- Can be refactored safely
+- Rarely ships regressions
+- Catches security violations before release
+- Detects data integrity failures early
+- Has a stable, trusted CI pipeline
+- Has a fast feedback loop
+- Is boringly reliable
+
+Engineers trust the test suite.
+They do not ignore it.
+They do not fear it.
+They rely on it.
+
+That is the standard.

+# Nix Tool Preference Directive
+
+## Core Instruction
+
+**Always prioritize Nix-based tools (`nix_nix`, `nix_nix_versions`, `nix-shell`, `nix run`, etc.) for querying packages, versions, options, environments, and reproducible workflows whenever relevant.**
+
+Nix ensures declarative, isolated, reproducible results. Use these before generic searches, manual installs, or distro tools.
+
+## Trigger Conditions
+
+- Package discovery/version info: `nix_nix` or `nix_nix_versions`.
+- Environment setup: `nix-shell`, `nix develop`.
+- NixOS/Home-manager config: `nix_nix action=options`.
+- Reproducibility/CI: Nix flakes/builds.
+
+**Fallback**: Native tools if Nix unsuitable; note Nix alternative.
+
+## Specific Tools
+
+### **`nix_nix`** - Query NixOS, Home Manager, Darwin, flakes, and more
+
+| Parameter | Description |
+|-----------|-------------|
+| `action` | `search`, `info`, `stats`, `options`, `channels`, `flake-inputs`, `cache` |
+| `source` | `nixos`, `home-manager`, `darwin`, `flakes`, `flakehub`, `nixvim`, `wiki`, `nix-dev`, `noogle`, `nixhub` |
+| `query` | Search term, name, or prefix |
+| `type` | `packages`, `options`, `programs`, `list`, `ls`, `read` |
+| `channel` | `unstable`, `stable`, `25.05` |
+| `limit` | 1-100 (or 1-2000 for flake-inputs read) |
+
+### **`nix_nix_versions`** - Get package version history from NixHub.io
+
+| Parameter | Description |
+|-----------|-------------|
+| `package` | Package name |
+| `version` | Specific version to find (optional) |
+| `limit` | 1-50 |
+
+## Key Use-Cases
+
+| Use-Case | Tool/Command | Example |
+|----------|--------------|---------|
+| Search packages | `nix_nix` | `nix_nix action=search query=ripgrep source=nixos` |
+| Find options | `nix_nix` | `nix_nix action=options query=services.nginx source=nixos` |
+| Flake inputs | `nix_nix` | `nix_nix action=flake-inputs query=read source=flakes` |
+| Version history | `nix_nix_versions` | `nix_nix_versions package=nodejs` |
+| Temporary tool | `nix run` | `nix run nixpkgs#ripgrep -- search_term` |
+| Project env | `nix develop` | Loads `flake.nix` deps |
+| Pure shell | `nix-shell --pure` | Isolated env |
+
+## Agent Integration
+
+- **Query packages/options first**: Use `nix_nix` before assuming availability.
+- **Pin versions**: Check `nix_nix_versions` for stable choices.
+- **Generate configs**: Create `shell.nix`/flakes based on queries.
+- **Verify**: `nix --version` if needed.
+
+## Example `shell.nix`
+
+````nix
+{ pkgs ? import <nixpkgs> {} }:
+
+pkgs.mkShell {
+  buildInputs = with pkgs; [ nodejs_20 python311 ripgrep ];
+}
+````
+
+## Flake Creation for Packages
+
+**Guideline**: Create `flake.nix` for building packages, reproducible dev shells, multi-language support, and cross-platform compatibility.
+
+**Triggers**:
+- Building language-specific packages (e.g., Rust via `crane`).
+- Configurable dev environments (Rust/Node/Go/etc.).
+- Use `nix_nix` first: e.g., `nix_nix action=search query=crane source=flakes` for libs.
+
+**Key Structure**:
+- **inputs**: `nixpkgs`, `flake-parts`, lang tools (`crane`, `fenix`, etc.).
+- **outputs**: `packages.default`, `devShells.default` with `shellHook`.
+- Multi-system: `x86_64-linux`, `aarch64-darwin`, etc.
+
+**Example `flake.nix`** (Rust MCP server + configurable dev envs via `dev-environments`):
+
+````nix
+{
+  description = "Rust documentation MCP server";
+  inputs = {
+    flake-parts.url = "github:hercules-ci/flake-parts";
+    nixpkgs.url = "github:NixOS/nixpkgs/nixos-unstable";

+    crane = {
+      url = "github:ipetkov/crane";
+    };
+  };

+        };
+    };
+}
+````
+
+**Usage**:
+- `nix develop` for dev shell.
+- `nix build` for package.
+- `nix run` for app.
+
+## uv2nix for Python Projects
+
+**When to use**: Python projects with `uv.lock` - handles complex dependencies not in nixpkgs.
+
+**Inputs needed**:
+```nix
+pyproject-nix.url = "github:pyproject-nix/pyproject.nix";
+uv2nix.url = "github:pyproject-nix/uv2nix";
+pyproject-build-systems.url = "github:pyproject-nix/build-system-pkgs";
+```
+
+**Critical API details**:
+- Function is `loadWorkspace`, NOT `loadUvWorkspace` (despite tool name)
+- Use `python = pkgs.python313`, NOT `inherit (pkgs) python313`
+- Creates virtual environments via `mkVirtualEnv`, not traditional derivations
+
+**Overlay composition order** (must be exact):
+1. `pyproject-build-systems.overlays.default`
+2. Project overlay from `workspace.mkPyprojectOverlay`
+3. Custom `pyprojectOverrides`
+
+**Pattern**:
+```nix
+workspace = uv2nix.lib.workspace.loadWorkspace { workspaceRoot = ./.; };
+overlay = workspace.mkPyprojectOverlay { sourcePreference = "wheel"; };
+pythonSet = (pkgs.callPackage pyproject-nix.build.packages {
+  python = pkgs.python313;
+}).overrideScope (lib.composeManyExtensions [
+  pyproject-build-systems.overlays.default
+  overlay
+  pyprojectOverrides
+]);
+in {
+  packages.default = pythonSet.mkVirtualEnv "env-name" workspace.deps.default;
+}
+```
+
+**Output**: Virtual env with executables in `result/bin/<package-name>`.
+
+## Prohibitions
+
+- Avoid non-reproducible installs (e.g., `apt`).
+- Avoid non-declarative package management (e.g., `nix-env -iA nixos.ripgrep` or `nix profile add nixpkgs#ripgrep`)
+- Always check Nix tools first.
+
+**Next**: Query a package with `nix_nix` or generate `shell.nix`.
