📝 Walkthrough

• Fixes empty App Logs output by waiting for editor layout readiness before appending log entries.
• Re-synchronizes log output when layout readiness times out.
• Prevents cleared logs from appearing again by preserving the latest sequence number for empty buffers.
• Adds LogViewModel.resync() to emit a fresh retained-history snapshot.
• Adds tests for clear isolation, resynchronization, and submission ordering.
• Returns append failures from IDEEditor.appendBatch and logs the failure.
• Risk: Log updates can wait up to two seconds for editor layout readiness.

Walkthrough

The log pipeline preserves sequence state after clearing, supports view-model resynchronization, and bounds editor layout waits. The output fragment requests a fresh snapshot after a layout timeout. Tests cover stale-entry exclusion, history replay, and event ordering.

Changes

Log rendering synchronization

Layer / File(s)	Summary
Log stream sequencing and resynchronization app/src/main/java/com/itsaky/androidide/logs/LogBuffer.kt, app/src/main/java/com/itsaky/androidide/viewmodel/LogViewModel.kt, app/src/test/java/com/itsaky/androidide/logs/LogBufferTest.kt, app/src/test/java/com/itsaky/androidide/viewmodel/LogViewModelTest.kt	Empty snapshots retain the latest issued sequence number. LogViewModel.resync() restarts the event generation and emits retained history. Tests cover clearing, replay, and submission ordering.
Layout-aware log appending app/src/main/java/com/itsaky/androidide/fragments/output/LogViewFragment.kt, editor/src/main/java/com/itsaky/androidide/editor/ui/IDEEditor.kt	Editor layout waits use a two-second timeout. The fragment updates content state before waiting, appends only after readiness, and requests resynchronization after timeout. IDEEditor.appendBatch returns append status, logs failures, and preserves cancellation.

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

Merge Risk: 🟡 Moderate · up to cc990

App Logs can still omit entries or stop updating when appending fails because failures are hidden and cancellation or fatal errors may be treated as normal failures. The PR is not merge-ready until this bounded reliability risk is fixed or explicitly accepted.

Poem

A rabbit watched the log lines flow,
Through cleared-out space where old lines go.
When layout waits, the stream resyncs,
Fresh snapshots hop across the links.
Failed appends return a warning sign,
And ordered lines arrive in time.
