 # Changelog
 
+## 2026-03-05 - 4.1.17 - fix(tsunpacker)
+use synchronous fs operations in tsunpacker to avoid readdir race conditions
+
+- Replaced async fs.promises.readdir/rename/rm/rmdir loops with fs.readdirSync/renameSync/rmSync/rmdirSync
+- Removed readdir retry loops that attempted to handle partial/stale readdir results
+- Updated comment to document rationale: avoid race conditions under signal pressure and XFS metadata lag
+- Note: function remains async but now performs blocking sync filesystem calls which may block the event loop during unpack
+
+## 2026-03-05 - 4.1.16 - fix(mod_unpack)
+handle partial readdir results from signal-interrupted getdents64 when unpacking to ensure sibling removal and nested moves complete
+
+- Loop readdir calls for destination directory until only the source folder remains to avoid partial-listing leftovers
+- Loop readdir calls for nested directory and repeatedly rename entries until the nested directory is empty
+- Prevents leftover files and incomplete moves when readdir returns partial results under signals
+
+## 2026-03-05 - 4.1.15 - fix(mod_unpack)
+flatten nested output directory without temporary rename steps to avoid race conditions
+
+- Replace rename-rm-rename strategy with: remove sibling entries in destination, move nested source entries up into the destination, then remove the now-empty nested folder.
+- Avoid creating temporary sibling directories and avoid removing the destination directory to reduce filesystem race conditions and metadata lag issues (XFS/NFS/etc.).
+- Remove removed removeEmptyDirectory helper and stop using FsHelpers.move/removeDirectory in unpack; import and use fs.promises methods (readdir, rm, rename, rmdir) directly.
+
+## 2026-03-05 - 4.1.14 - fix(fs)
+replace execSync and fsync workarounds with atomic async FsHelpers operations to avoid XFS races and shell dependencies
+
+- Removed child_process.execSync usage and shell mv/rm commands in mod_unpack and mod_compiler.
+- Removed syncDirectoryTree and fsync-based workaround from the compiler module.
+- Use FsHelpers.move and FsHelpers.removeDirectory (async rename/remove) for atomic filesystem operations during unpack.
+- Await performUnpack directly and simplify unpack flow to improve portability and reliability on XFS and other filesystems.
+
+## 2026-03-05 - 4.1.13 - fix(mod_unpack)
+Use child_process.execSync (mv/rm) to perform unpack atomically, replacing async fs operations and logs to avoid ENOENT/partial directory listings on XFS
+
+- Replaced async fs.promises.rename/rm and readdir/stat debugging with execSync rm -rf and mv operations for sequential, atomic moves
+- Imported execSync from child_process and removed verbose console logging and extra fs checks
+- Addresses race conditions observed on filesystems like XFS where libuv async operations can return partial results or ENOENT errors
+
+## 2026-03-05 - 4.1.12 - fix(mod_compiler)
+replace runtime require calls with top-level imports and use execSync/path.join for filesystem sync and traversal
+
+- Added top-level imports: path and execSync from child_process
+- Replaced require('child_process').execSync('sync') with execSync('sync') to force fs sync
+- Replaced require('path').join(...) with path.join(...) when recursing directories
+- Refactor is purely local/maintenance-focused (consistency and slight performance/readability improvement); no functional change expected
+
+## 2026-03-05 - 4.1.11 - fix(mod_compiler)
+flush directory entries before unpack to avoid XFS delayed-log causing partial readdir results
+
+- Add fs import and call child_process.execSync('sync') before unpacking compiled output to force kernel-level sync
+- Add syncDirectoryTree(dir) to recursively open and fsync directory file descriptors and traverse subdirectories
+- Call syncDirectoryTree on the destination directory before performing unpack to ensure TypeScript writeFileSync entries are committed (prevents partial readdir results on XFS)
+- Errors during directory sync are ignored to avoid breaking normal flow
+
+## 2026-03-05 - 4.1.10 - fix(unpack)
+use atomic renames to flatten nested output and make unpacking more reliable
+
+- Replace per-entry moves with an atomic 3-step strategy: rename nested dir to a temp location, remove the destination dir, then rename temp back to the destination to avoid partial readdir/move under signal pressure.
+- FsHelpers.move switched from sync rename to fs.promises.rename to work with async flows.
+- Use fs.promises.rm with retries and explicit temp-dir cleanup to handle previous failed runs.
+- Add diagnostic logging and verification of intermediate states.
+- Removed the older removeSiblingDirectories and moveNestedContentsUp methods in favor of the new rename-based approach.
+
+## 2026-03-05 - 4.1.9 - fix(fs)
+improve filesystem helpers: use sync rename for reliability on certain filesystems; retry rmdir with delays and avoid recursive rm; bump @push.rocks/smartfs to ^1.3.2
+
+- move(): use fs.renameSync to improve reliability on XFS/mounted filesystems where async rename can be interrupted by process managers
+- removeEmptyDirectory(): retry fs.promises.rmdir up to 5 attempts with incremental delays; return on ENOENT; avoid recursive rm on ENOTEMPTY to prevent removing still-valid references
+- Dependency bump: @push.rocks/smartfs from ^1.3.1 to ^1.3.2
+
+## 2026-03-05 - 4.1.8 - fix(unpack)
+catch unpack errors and add verbose unpack logging
+
+- Wrap performUnpack call in the compiler to catch and log exceptions so unpack failures don't crash the process
+- Log the number of directories and files being unpacked when moving nested contents to aid debugging
+
+## 2026-03-05 - 4.1.7 - fix(fs/compiler/unpack)
+robustify directory removal and remove noisy diagnostic logging
+
+- Use fs.promises.rm with force, maxRetries and retryDelay in removeDirectory to reduce intermittent failures during removals.
+- Handle ENOTEMPTY in removeEmptyDirectory by falling back to a recursive rm and ignore ENOENT to avoid errors from transient filesystem metadata lag.
+- Remove several diagnostic/verbose console logs in the compiler and unpacker paths to reduce noisy output and simplify flow.
+- Short-circuit unpack logic when no nesting is detected to avoid unnecessary work and logs.
+- No public API or behavior-breaking changes; suitable for a patch release.
+
+## 2026-03-05 - 4.1.6 - fix(mod_compiler)
+add diagnostic logging to report dist_ts and output directory contents after each compilation task and after import-path rewriting
+
+- Adds DIAG-CROSSTASK logs to inspect dist_ts subdirectories after each task when not in quiet or JSON mode
+- Adds DIAG-FINAL logs to report directory names and file counts for each successful output dir after import-path rewriting
+- Diagnostics use dynamic fs import and are non-intrusive: gated by isQuiet/isJson and errors are ignored
+
+## 2026-03-05 - 4.1.5 - fix(diagnostics)
+add diagnostic logging around compilation and unpack to aid troubleshooting
+
+- Enable TypeScript CompilerOptions.listEmittedFiles to surface emitted file info
+- Log destination directory contents and emitted file/error counts after compile and after unpack (only when not quiet and not json)
+- Add unpack-specific diagnostic logs: shouldUnpack skip, detectNesting result and nestedPath, and nested/destination directory listings before removing sibling directories
+- All logs use console.log and are wrapped in try/catch to avoid throwing; changes are informational and non-breaking
+
+## 2026-03-05 - 4.1.4 - fix(deps)
+bump @git.zone/tspublish dependency to ^1.11.2
+
+- Updated @git.zone/tspublish from ^1.11.0 to ^1.11.2 in package.json
+
+## 2026-03-04 - 4.1.3 - fix(deps)
+bump dependencies: @push.rocks/smartcli, @push.rocks/smartlog, @git.zone/tstest, and @types/node to their newer versions
+
+- @push.rocks/smartcli: ^4.0.19 -> ^4.0.20
+- @push.rocks/smartlog: ^3.1.10 -> ^3.2.1
+- @git.zone/tstest: ^3.1.4 -> ^3.2.0
+- @types/node: ^25.0.3 -> ^25.3.3
+- Non-breaking dependency version bumps
+
 ## 2026-01-04 - 4.1.0 - feat(docs)
 update README with improved docs and monorepo/tspublish guidance; namespace and extend npmextra.json with release registries; bump several dependencies
