v4.4.0

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
 
+## 2026-03-24 - 4.4.0 - feat(config)
+add smartconfig metadata and update TypeScript build configuration docs
+
+- replace npmextra.json with .smartconfig.json and include it in published files

+- expand documentation for import path rewriting, structured logging, and the compilation pipeline
+
+## 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+remove outdated comment about using synchronous rm to avoid XFS metadata corruption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

+4. **Phase 4: Path Rewrite** - Rewrite cross-module import paths in output dirs
+
 ## Unpack Feature
 
 When TypeScript compiles files that import from sibling directories, it creates nested output:
 ```
 dist_ts_core/
-  ts_core/        ← nested output
-  ts_shared/      ← pulled-in dependency
+  ts_core/        <- nested output
+  ts_shared/      <- pulled-in dependency
 ```
 
 The unpack feature automatically flattens this to:
 ```
 dist_ts_core/
-  index.js        ← flat
+  index.js        <- flat
 ```
 
 ### Configuration
 - Reads `tspublish.json` from source folder
-- `unpack: true` (default if not present) → flatten output
-- `unpack: false` → skip unpacking
-
-### Implementation
-- `TsUnpacker` class in `mod_unpack/classes.tsunpacker.ts`

-### Monorepo Support with tspublish 📦
+### Import Path Rewriting
+
+When working with multi-module projects (multiple `ts_*` folders), TypeScript compiles import paths relative to source directories. After compilation and unpacking, these paths would be wrong because the directory structure changes.
+
+tsbuild automatically detects all `ts_*` folders in the project and rewrites import paths in the compiled output:
+
+```
+# Source code
+import { helper } from '../ts_shared/helper.js';
+
+# Compiled output (after rewriting)
+import { helper } from '../dist_ts_shared/helper.js';
+```
+
+This works for ES module imports, dynamic `import()` calls, and CommonJS `require()` statements. The rewriting happens automatically as part of `compileGlob()`.

+### Structured Logging
 
-## 🔄 CI/CD Integration
+tsbuild uses a 4-level visual hierarchy for console output, making it easy to follow compilation progress:
+
+- **HEADER** - Top-level section start (emoji + bold text + separator)
+- **STEP** - Major action within a section (emoji + text)
+- **DETAIL** - Supplementary info under a step (indented)
+- **SUCCESS/ERROR/WARN** - Outcome indicators with color coding
+
+All output uses ANSI color codes for terminal readability. Use `--quiet` to suppress output or `--json` for machine-readable format.
