Pi Mono: Hardening Session Resume and Agent Reliability

Good morning, it's September 19th, and this is Pi Mono.
The dominant pattern today is resilience work in the coding agent, especially around sessions and retries. Several PRs independently close gaps where the agent could stall, crash, or silently do the wrong thing.
Start with session identity. PR 9754 fixes a case where resuming a session from a git worktree of the same repo incorrectly offered a cross-project fork instead of a silent resume — the fix resolves symlinked session directories properly. PR 9734 closes a related gap: ambiguous session or fork ID prefixes used to…
Next, turn and retry robustness. PR 9744 adds a slash command to resume a turn abandoned after failed connection retries — useful for anyone running local models where a server restart or flaky connection used to dead-end the session. PR 9738 fixes a subtler bug: deferred custom messages from compaction weren't…
A third thread is defensive UI and input handling. PR 9762 guards the TUI against extension tools returning malformed results, preventing a full process crash from one bad tool response. PR 9746 fixes file autocomplete to treat CJK punctuation as a word boundary, and PR 9745 clarifies the copy shortcut…
