Split the monolithic transaction into focused modules: append-only crash-recoverable journal under ~/.elydora/transactions with owner tokens and per-transaction namespaces, staged atomic publication (stage .pending, fsync, rename, fsync), platform-specific atomic replacement (MoveFileEx, renameat2, renamex_np), private-directory hardening per OS, lock-guarded recovery, and workspace cleanup that removes only transaction-created empty directories. Add the Kiro IDE 1.0 plugin: strict v1 hook schema with one enabled PreToolUse guard and PostToolUse audit pair bound to the active workspace, agent-to-workspace identity binding in runtime config, and exact migration of the legacy elydora-audit.kiro.hook contract. Gates: go test ./... and -race pass, go vet clean, govulncheck reports zero reachable vulnerabilities, git diff --check clean.
