 # Changelog
 
+## 2026-03-05 - 4.2.3 - fix(compiler)
+defer unpacking until after all compilations and remove diagnostic filesystem syncs to avoid XFS metadata visibility issues
+
+- Queue pending unpack operations during compilation and run them after all compile tasks complete to avoid modifying output directories while other compilations are writing.
+- Remove TypeScript sys interception, execSync('sync') calls, and per-unpack fs.fsyncSync usage that attempted to work around XFS delayed metadata commits; rely on performing all unpacks after compilation instead.
+- Clean up noisy diagnostic code (external 'ls' comparisons, readdir snapshots) and simplify logging of unpack results.
+- Remove unused imports (fs and child_process.execSync) from the compiler module.
+
+## 2026-03-05 - 4.2.2 - fix(compiler)
+force global filesystem sync to flush XFS delayed logging and add diagnostics comparing Node's readdirSync with system ls to detect directory entry inconsistencies
+
+- Replace per-directory fs.fsyncSync loop with execSync('sync') to ensure parent B+tree metadata is flushed on XFS
+- Import execSync from child_process
+- Add diagnostic comparison: run ls -1 and compare its entries to fs.readdirSync; log mismatches and full entry lists for debugging Node.js caching/readdir inconsistencies
+
+## 2026-03-05 - 4.2.1 - fix(compiler)
+use TypeScript sys hooks instead of fs monkeypatching to detect writes/deletes in previous output directories
+
+- Replace direct fs.* monkeypatching with interception of typescript.sys.writeFile, typescript.sys.deleteFile and typescript.sys.createDirectory
+- Add guards for optional sys.deleteFile before overriding it and preserve original sys methods to restore after compilation
+- Update diagnostic messages to reference TypeScript sys ops and add an informational message when no ops are observed
+- Reduce surface area of changes by avoiding global fs changes and focusing on TypeScript's sys API for safer interception
+
+## 2026-03-05 - 4.2.0 - feat(mod_compiler)
+add diagnostic interception of fs operations to detect and report unexpected file system changes in previously compiled output directories during compilation
+
+- Wraps fs.unlinkSync, fs.rmSync, fs.rmdirSync, fs.renameSync and fs.writeFileSync to record operations targeting other successful output directories during a compile.
+- Enabled only when there are previously compiled output dirs and when not running in quiet or JSON mode; original fs methods are restored after compilation.
+- Logs up to 30 intercepted operations and prints a summary count if any ops were observed; intercepted calls still perform the original fs action (diagnostic-only).
+- No functional change to compilation behavior beyond additional diagnostic reporting.
+
+## 2026-03-05 - 4.1.26 - fix(compiler)
+fsync output directories after unpack to avoid XFS delayed logging causing corrupt or invisible directory entries during subsequent TypeScript emits
+
+- Force fsync on each successful output directory (open, fsync, close) before the next compilation step.
+- Prevents XFS delayed logging from making directory entries invisible or corrupted during TypeScript emit operations.
+- Operation swallows errors if a directory doesn't exist yet; non-breaking fix with small additional IO.
+
+## 2026-03-05 - 4.1.25 - fix(mod_unpack)
+flush directory metadata on XFS before reading and use readdirSync-based iteration to avoid missing entries when unpacking
+
+- Call fs.fsyncSync on destination and nested directory file descriptors to force XFS to commit delayed directory metadata (addresses XFS CIL delayed logging causing incomplete readdir/opendir results).
+- Replace opendirSync/readSync loops with readdirSync-based iteration for simpler, deterministic directory listing.
+- Remove unused moved counter and update diagnostic log to report nestedEntries.length for moved entry count.
+
+## 2026-03-05 - 4.1.24 - fix(mod_unpack)
+iterate directories with opendirSync/readSync to avoid missing entries on XFS and ensure directory handles are closed
+
+- Replaced readdirSync loops with opendirSync + readSync for destination and nested directories to provide a single stable directory handle during iteration
+- Added explicit closeSync() calls to close directory handles and avoid resource leaks
+- Avoids partial results/missed entries that can occur when repeatedly calling readdirSync (observed on XFS with delayed metadata)
+- Preserves existing renameSync move logic and increments moved counter while cleaning up the now-empty nested directory
+
+## 2026-03-05 - 4.1.23 - fix(mod_unpack)
+handle partial readdirSync results when moving nested directory entries and add diagnostic log
+
+- Loop over readdirSync results until the nested directory is empty to avoid missing entries from partial reads
+- Count moved entries and print a diagnostic message with the final destination entry count
+- Keep removal of the now-empty nested directory (fs.rmdirSync) after moving contents
+
+## 2026-03-05 - 4.1.22 - fix(mod_compiler)
+improve logging of successful output directories to include a sorted list of entries and use a shortened relative path
+
+- Adds shortDir variable to display relative path instead of repeating inline replace(this.cwd + '/')
+- Appends a sorted, comma-separated list of directory entries to the log output for easier inspection
+- Change located in ts/mod_compiler/classes.tscompiler.ts
+
+## 2026-03-05 - 4.1.21 - fix(compiler)
+log emitted files written outside expected destination directory for diagnostics
+
+- Adds diagnostic logging for emitted files that are not under the configured destDir, listing up to 20 example paths and reporting the remaining count.
+- Logging is conditional: only when not in quiet mode and not emitting JSON.
+- Diagnostic runs after compilation (post-compile) and before unpacking of outputs; paths are trimmed using the process cwd for readability.
+
+## 2026-03-05 - 4.1.20 - fix(mod_compiler)
+add diagnostic snapshots for output directories around clear and compile steps
+
+- Introduce diagSnap helper to log entry and directory counts for successful output directories when not in quiet or JSON mode
+- Call diagSnap before clearing the destination directory, after clearing, and after compilation to aid debugging of missing or unexpected outputs
+- Behavior for emitted files and unpacking is unchanged; this is observational/logging-only instrumentation
+
+## 2026-03-05 - 4.1.19 - fix(mod_fs)
+use synchronous rm to avoid XFS metadata corruption when removing directories
+
+- Replaced async fs.promises.rm with synchronous fs.rmSync in removeDirectory to avoid observed XFS metadata corruption affecting sibling entries under libuv thread-pool and signal pressure
+- Retains previous options: recursive, force, maxRetries, retryDelay
+- Adds inline comment documenting the rationale for using a synchronous removal
+
 ## 2026-03-05 - 4.1.18 - fix(mod_compiler)
 add diagnostic logging of output directory states after compilation and after import-path rewriting to aid debugging
