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.

## Verify Architectural Boundaries with Tests
|
|
|
|
Use automated tests to enforce that dependency rules are followed. Architecture tests catch violations before they become entrenched patterns.
|
|
|
|
**Incorrect (no boundary verification):**
|
|
|
|
```java
|
|
// Over time, developers add shortcuts
|
|
// domain/Order.java
|
|
import org.springframework.stereotype.Component; // Framework in domain!
|
|
import javax.persistence.Entity; // JPA in domain!
|
|
|
|
// application/CreateOrderUseCase.java
|
|
import com.stripe.Stripe; // Direct payment vendor dependency!
|
|
import infrastructure.email.SendGridClient; // Infrastructure in application!
|
|
|
|
// No tests catch these violations
|
|
// They accumulate until refactoring becomes impossible
|
|
```
|
|
|
|
**Correct (architecture tests enforce boundaries):**
|
|
|
|
```java
|
|
// Using ArchUnit (Java) or similar tools
|
|
@AnalyzeClasses(packages = "com.myapp")
|
|
class ArchitectureTest {
|
|
|
|
@ArchTest
|
|
static final ArchRule domain_should_not_depend_on_infrastructure =
|
|
noClasses()
|
|
.that().resideInAPackage("..domain..")
|
|
.should().dependOnClassesThat()
|
|
.resideInAPackage("..infrastructure..");
|
|
|
|
@ArchTest
|
|
static final ArchRule domain_should_not_use_frameworks =
|
|
noClasses()
|
|
.that().resideInAPackage("..domain..")
|
|
.should().dependOnClassesThat()
|
|
.resideInAnyPackage(
|
|
"org.springframework..",
|
|
"javax.persistence..",
|
|
"jakarta.persistence.."
|
|
);
|
|
|
|
@ArchTest
|
|
static final ArchRule usecases_should_not_access_controllers =
|
|
noClasses()
|
|
.that().resideInAPackage("..application..")
|
|
.should().dependOnClassesThat()
|
|
.resideInAPackage("..interface..");
|
|
|
|
@ArchTest
|
|
static final ArchRule dependencies_point_inward =
|
|
layeredArchitecture()
|
|
.consideringAllDependencies()
|
|
.layer("Domain").definedBy("..domain..")
|
|
.layer("Application").definedBy("..application..")
|
|
.layer("Infrastructure").definedBy("..infrastructure..")
|
|
.layer("Interface").definedBy("..interface..")
|
|
.whereLayer("Domain").mayNotAccessAnyLayer()
|
|
.whereLayer("Application").mayOnlyAccessLayers("Domain")
|
|
.whereLayer("Infrastructure").mayOnlyAccessLayers("Domain", "Application")
|
|
.whereLayer("Interface").mayOnlyAccessLayers("Domain", "Application");
|
|
}
|
|
|
|
// TypeScript equivalent using dependency-cruiser
|
|
// .dependency-cruiser.js
|
|
module.exports = {
|
|
forbidden: [
|
|
{
|
|
name: 'domain-no-infra',
|
|
from: { path: '^src/domain' },
|
|
to: { path: '^src/infrastructure' }
|
|
},
|
|
{
|
|
name: 'domain-no-frameworks',
|
|
from: { path: '^src/domain' },
|
|
to: { path: 'node_modules/(express|prisma|typeorm)' }
|
|
}
|
|
]
|
|
};
|
|
```
|
|
|
|
**Run in CI:**
|
|
```yaml
|
|
# .github/workflows/ci.yml
|
|
- name: Check architecture
|
|
run: |
|
|
./gradlew archTest # Java with ArchUnit
|
|
npx depcruise src # TypeScript with dependency-cruiser
|
|
```
|
|
|
|
**Benefits:**
|
|
- Violations caught immediately in CI
|
|
- New developers can't accidentally break boundaries
|
|
- Architecture documentation that stays accurate
