Three independently ugly bugs that all fed the same log flood:
* Electron's `WebFrameMain.send` writes every "Render frame was disposed"
to stderr via `console.error`. When the worker fans a second
agent-event past a reloading renderer, we produced thousands of
identical lines and stalled the main loop on stderr I/O. Added a
`mainFrame.detached` guard so the send is short-circuited before
Electron's own catch block fires, and installed a targeted filter in
`suppress-warnings.ts` (now actually imported from the entry point)
so the specific `console.error("Error sending from webFrameMain:"…)`
noise never reaches the terminal. Any other payload still surfaces.
* `dispatchAgentMessage` accepted the human-reader sentinel as a wake
target when an agent replied to `__board__` — `wakeAgentIfPossible`
then called `db.getAgent("__board__")`, threw, and the dispatcher
kept repeating on every send. Strip `HUMAN_SENDER_ID` at
`resolveMessageWakeTargets`, and keep a defense-in-depth guard in the
heartbeat so a stray caller (future automation fan-out) cannot
reintroduce the crash.
* Pi's skills loader rejects any SKILL.md whose frontmatter `name`
diverges from its parent directory. The four bundled `my-writing-style`
copies declared `name: writing-style-skill`, so every install emitted
a warning and dropped the skill. They also lived as orphan gitlinks
(mode 160000 without .gitmodules), and the global `*.md` gitignore
hid every other SKILL.md from version control. Fixed the frontmatter
to match the dir, converted the dangling submodules to plain trees,
and allowlisted `builtin-skills/**/*.md` so a fresh clone carries the
catalogue instead of silently losing it.

Domain Layer Has Zero Framework Dependencies
The domain layer (entities and domain services) should have zero dependencies on frameworks, ORMs, or external libraries. Only language primitives and domain-specific code.
Incorrect (domain depends on framework):
// Domain entity with framework dependencies
using Microsoft.EntityFrameworkCore;
using System.ComponentModel.DataAnnotations;
using Newtonsoft.Json;
namespace Domain.Entities
{
[Table("products")]
public class Product
{
[Key]
[DatabaseGenerated(DatabaseGeneratedOption.Identity)]
public int Id { get; set; }
[Required]
[MaxLength(100)]
[JsonProperty("product_name")]
public string Name { get; set; }
[Column(TypeName = "decimal(18,2)")]
public decimal Price { get; set; }
// EF Core navigation property
public virtual Category Category { get; set; }
// Framework-specific validation
public IEnumerable<ValidationResult> Validate(ValidationContext context)
{
if (Price < 0)
yield return new ValidationResult("Price cannot be negative");
}
}
}
// Domain now depends on: EF Core, DataAnnotations, Newtonsoft.Json
// Cannot exist without these frameworks
Correct (pure domain):
// Domain entity - zero framework dependencies
namespace Domain.Entities
{
public class Product
{
public ProductId Id { get; }
public string Name { get; private set; }
public Money Price { get; private set; }
public CategoryId CategoryId { get; private set; }
public Product(ProductId id, string name, Money price, CategoryId categoryId)
{
if (string.IsNullOrWhiteSpace(name))
throw new InvalidProductNameException();
if (name.Length > 100)
throw new ProductNameTooLongException(name.Length, 100);
if (price.IsNegative)
throw new NegativePriceException(price);
Id = id;
Name = name;
Price = price;
CategoryId = categoryId;
}
public void UpdatePrice(Money newPrice)
{
if (newPrice.IsNegative)
throw new NegativePriceException(newPrice);
Price = newPrice;
}
}
}
// Infrastructure - framework dependencies isolated here
namespace Infrastructure.Persistence
{
using Microsoft.EntityFrameworkCore;
[Table("products")]
internal class ProductEntity
{
[Key] public int Id { get; set; }
[MaxLength(100)] public string Name { get; set; }
[Column(TypeName = "decimal(18,2)")] public decimal Price { get; set; }
public int CategoryId { get; set; }
}
internal class ProductMapper
{
public Product ToDomain(ProductEntity entity) => /* ... */
public ProductEntity ToEntity(Product product) => /* ... */
}
}
How to check domain purity:
# Domain project should have no package references
dotnet list Domain.csproj package
# Should return: No packages found
# Or in package.json
# "dependencies": {} should be empty or only contain domain libraries
