feat(pst): PostCompact hook to recover ledger state after auto compact#65
Merged
Conversation
…paction Adds pst-post-compact.rb wired to the PostCompact auto event. After an auto compact, the hook re-inits the ledger JSON if the file was lost and emits a user-visible summary of in-flight tasks. Claude picks up ledger state on the next turn via the rule-22 nudge in pst-prompt-reminder.rb (PostCompact stdout is shown to the user only, not injected into context). Also fixes stale hook binaries: pst-mode.rb's install step now includes pst-post-compact.rb so re-arming keeps all hooks current.

…ocess pst-ledger.rb resolve_sid checks ENV['CLAUDE_SESSION_ID'] first; without it, stdin is /dev/null so resolve_sid returns '' and init exits 1 silently. Pass the session id as an env var so the subprocess can resolve it. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_019BCr5Qxi8jXnG2Rr7zdkw1
