Summary

Closes #39.

• Scope cycle acknowledgement and status timestamps to the tmux server lifetime plus pane ID.
• Capture server PID, start time, and socket in the pane snapshot; hash that identity into a server-specific ledger directory.
• Ignore legacy unscoped records and disable persistent history when server identity is unavailable.
• Preserve attention history through detach/reattach and same-server pane survival; reset it after a full restart, including the same socket.
• Document the fresh attention sweep after restart without changing tmux-resurrect behavior.

Verification

• Test-first: four regressions failed before production changes; focused ledger/server tests now pass 10/10.
• Real tmux tests exercise concurrent servers with reused pane IDs, control-mode attach/detach/reattach, same-server session churn, and restart on the same socket.
• Full suite passes 280/280 in a normal-clone snapshot; all nine committed files were byte-verified against that snapshot.
• Prepared worktree passes 279/280. The remaining sync-plugin test fails because rsync's .git/ exclusion does not exclude a worktree .git file. The identical failure was reproduced on the unchanged baseline (274/275); unrelated sync behavior was not modified.
• Passed lint, typecheck, formatting, CLI smoke check, shellcheck, shell formatting, and diff whitespace checks.
• Independent Codex reviews of both the uncommitted change and committed base-to-head diff found no actionable regressions. Reviewer sandbox restrictions prevented its real-tmux tests; the external real-tmux runs passed.

Limits

• Old server ledger directories are retained; pruning is separate housekeeping.
• Server identity uses tmux PID/start-time/socket metadata. An exact tuple collision is theoretically possible with PID reuse and identical second-resolution start time.
