Summary

  • update Oxlint and @oxlint/plugins from 1.78.0 to 1.80.0
  • validate channel-task creation at the HTTP boundary and normalize supplied titles in the store
  • replace conditional empty-object spreads and remove the no-op channel-task serializer
  • narrow notification routing to the state it actually consumes, removing as never fixtures
  • remove nearby unused destructures and unnecessary Set copies

Validation

  • pnpm typecheck
  • pnpm test — 2,166 main-suite tests passed (plus broker, Electron, launcher, and packaged-server checks)
  • changed-line Oxlint scan — 0 diagnostics
  • git diff --check

Existing lint backlog

The full repository lint remains red from drift already present on main: 1,633 anti-slop errors and 39 warnings across older subsystems. This pass reduces the total diagnostics from 1,690 to 1,672, introduces none on changed lines, and does not disable or weaken any rule. That backlog should be split into subsystem-sized follow-up PRs rather than hidden inside this channel cleanup.

Summary by CodeRabbit

  • Bug Fixes
    • Group task titles are now trimmed and limited to 80 characters when created.
    • Invalid task titles, such as numbers or other non-text values, are rejected with a clear HTTP 400 error.
    • Group task data is now returned consistently across group and task views.
  • Improvements
    • Notification routing and task lifecycle handling have been made more reliable.

Review Change Stack

📝 Walkthrough

Walkthrough

Changes

Group task flow

Layer / File(s) Summary
Task API validation and responses
server/index.ts, server/index.test.ts
Group-task creation now rejects non-string titles with HTTP 400. Group payloads and task endpoints return task records directly.
Task title normalization
server/store.ts, server/group-tasks.test.ts
New task titles are trimmed and truncated to 80 characters. Tests cover this behavior.

Server maintenance

Layer / File(s) Summary
Group record construction
server/store.ts
Group migration and creation use explicit conditional assignments while preserving persisted fields.
Server iteration and discarded fields
server/store.ts, server/index.ts
SSE listener iteration and discarded-field destructuring were simplified.

Notification routing types

Layer / File(s) Summary
Notification routing contract and fixtures
src/state/store.tsx, src/state/store.test.ts
Notification routing uses dedicated local interfaces. Test fixtures no longer use as never.

Lint tooling

Layer / File(s) Summary
Oxlint development dependencies
package.json
Oxlint packages were upgraded from 1.78.0 to 1.80.0.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🔵 Low · up to 97f1e

Store change notifications may now behave differently when callbacks add or remove subscriptions during delivery, potentially skipping a listener or notifying a newly added listener. The risk is localized and the PR is otherwise mergeable with explicit owner awareness or a follow-up to preserve snapshot semantics.

Preserve snapshot semantics in Store.emit.

Store.onChange allows callbacks to add or remove listeners. Iterating the live this.listeners set can skip a listener or deliver the current change to a newly added listener. Iterate over [...this.listeners] instead.
