Entry ${targetId} not found

Error message

Entry ${targetId} not found

What it means

appendLabelChange writes a label entry that targets an existing entry by id (targetId). If the target id is absent from the session index, the label would reference a nonexistent entry, so the call throws before recording anything. Only labels on live entries in the currently loaded session are allowed.

Solutions

1. Refresh the entry list from the current SessionManager and use a currently valid entry id.
2. Check the target still exists before labelling (lookup/getEntry first).
3. Reload or switch to the session that actually contains the target entry.
4. Skip labels for entries missing from the index (they were compacted away).

Example fix

// before
mgr.appendLabelChange(oldId, "done"); // may throw
// after
const target = mgr.getEntry(oldId);
if (target) mgr.appendLabelChange(oldId, "done");

if (!mgr.hasEntry(targetId)) {
  return; // entry was compacted away or belongs to another session
}

function entryExists(mgr, id) {
  return mgr.getEntry(id) != null;
}

try {
  mgr.appendLabelChange(targetId, label);
} catch (err) {
  if (/Entry .* not found/.test(err.message)) {
    logger.warn("Label target missing; skipping", { targetId });
  } else throw err;
}

When it happens

Trigger: Calling appendLabelChange(targetId, label) with an id not present in the current session's entry index — id from another session, pruned by compaction, fabricated, or from a stale in-memory list after reloading the session file.

Common situations: Labelling entries after the session was compacted (old ids gone); mixing ids across branched sessions; UI holding stale selection while the session reloaded underneath it.
