What's Wrong?

claude --from-pr <N> reports "No conversations found in this project" even though a session linked toPR #N exists on disk (its transcript under ~/.claude/projects/<project>/ contains the pr-link entry with
"prNumber":<N>).

Cause, from observing picker behavior: the session picker loads/enriches sessions in pages (~50 per page), most-recently-modified first, and the --from-pr filter is applied only to pages already loaded. Additional pages
load on scroll — but with zero matching rows visible there is nothing to scroll, so later pages never load. Any PR whose linked session is older than the most recent ~50 sessions is permanently unfindable via --from-pr, and
the picker presents this as if the conversation does not exist.

A second, related problem: while the picker is still enriching (large transcript store), it displays "No conversations found in this project" instead of a loading state, so even a findable session can look gone if the user quits early.

What Should Happen?

• The --from-pr filter should search all of the project's sessions (or keep loading pages until a match or exhaustion), not just the most recent page(s).
• While loading, the picker should show a loading indicator rather than "No conversations found".

Steps to Reproduce

## Steps to reproduce

1. In a repo where Claude created a PR (session has a pr-link entry — verify with grep -l '"prNumber":<N>,' ~/.claude/projects/<project-dir>/*.jsonl).
2. Accumulate 50+ newer sessions in that project (busy repos with worktree/subagent workflows reach this within days; our project dir has ~2,400 session files).
3. Run claude --from-pr <N> from the repo root.
4. Picker shows "No conversations found in this project." indefinitely. Ctrl+W / Ctrl+A don't help. claude --resume <session-id> (id taken from the grep above) resumes the same session fine, confirming the transcript is

intact and resumable.

Reproduced with PRs whose sessions were ~3.5 weeks old; PRs from the last day or two are found instantly, consistent with the recency-window explanation.
