Bead bf-3wya: Transcript Byte Offset Capture
Task
Capture transcript byte offset at bracketed-paste write for stream-json reader.
Implementation
The implementation was already complete in src/session.rs at lines 363-375:
// Check if phase changed to PromptInjected and notify watchdog
let current_phase = startup.phase();
if last_phase != *current_phase && current_phase.is_prompt_injected() {
watchdog_state_clone.mark_prompt_injected();
// Spawn stream-json reader at PROMPT_INJECTED for stream-json output
if matches!(output_format, crate::cli::OutputFormat::StreamJson) {
// Calculate byte offset: current transcript file size, or 0 if not exists
let start_offset = std::fs::metadata(&transcript_path)
.map(|m| m.len())
.unwrap_or(0);
stream_json_handle = Some(emitter::spawn_stream_json_reader(
transcript_path.clone(),
start_offset,
));
stream_json_spawned_clone.store(true, std::sync::atomic::Ordering::SeqCst);
}
}
Acceptance Criteria Met
- ✅ Identifies exact point where bracketed-paste write completes (phase change to
PromptInjected) - ✅ Captures file size using
std::fs::metadata(&transcript_path).map(|m| m.len()).unwrap_or(0) - ✅ Stores offset in
start_offsetvariable for use by reader thread - ✅ Handles missing transcript case with
.unwrap_or(0)
Changes
- Fixed warning: removed unnecessary
mutfromstream_json_spawnedvariable (line 305) - All tests pass (90 passed)
