v4.3.0

Restructured compileGlob() into three distinct phases:
1. Resolve glob patterns and clean ALL output directories upfront
2. Compile all TypeScript tasks (no filesystem cleanup during this phase)
3. Unpack all outputs after all compilations complete

This prevents XFS metadata corruption from rm operations overlapping
with TypeScript compilation writes to sibling directories.

 # Changelog
 
+## 2026-03-06 - 4.3.0 - feat(mod_logger)
+add centralized TsBuildLogger and replace ad-hoc console output with structured, colored logging
+
+- Add ts/mod_logger/classes.logger.ts providing header/step/detail/success/error/warn/indent utilities with ANSI color support
+- Export logger from ts/mod_logger/index.ts and re-export from ts/index.ts
+- Replace console.log/console.error/console.warn calls in mod_cli, mod_compiler, and mod_unpack with TsBuildLogger methods for consistent, hierarchical output
+- Refactor error-summary, emit and type-check output to use logger separators, colors, and structured messages
+
+## 2026-03-05 - 4.2.6 - fix(meta)
+no changes
+
+- Current package version: 4.2.5
+- No code or file changes detected in this commit; no release required
+
+## 2026-03-05 - 4.2.5 - fix(compiler)
+yield to the event loop after TypeScript emit to allow pending microtasks and I/O to settle before reading or modifying the output directory
+
+- Added await new Promise(resolve => process.nextTick(resolve)) immediately after program.emit()
+- Prevents race conditions by allowing libuv write completions and other deferred callbacks to complete before accessing the output directory
+- File changed: ts/mod_compiler/classes.tscompiler.ts
+
+## 2026-03-05 - 4.2.4 - fix(fshelpers)
+remove outdated comment about using synchronous rm to avoid XFS metadata corruption
+
+- Comment-only change in ts/mod_fs/classes.fshelpers.ts; no runtime or API behavior changes
+- Bump patch version from 4.2.3 to 4.2.4
+
+## 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
+
+- Imported fs to allow reading output directories for diagnostics
+- Logs entries and directory counts for each successful output directory both pre- and post-import-path-rewrite
+- Diagnostics are gated by !isQuiet && !isJson and are read-only (no behavior change)
+- Tags used: 'diag' (post-compilation) and 'diag-post-rewrite' (after rewriting) to help identify missing or unexpected output folders
+
+## 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
