 # Changelog
 
+## 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
