+## Update: 13:17 PT — harden sync.sh purge_garbled_paths (locale fix)
+
+During the prior save's sync, `purge_garbled_paths()` printed `grep: -P supports only unibyte and
+UTF-8 locales` — its `grep -P` (PCRE) guard refuses to run on BEAST's Git Bash locale, so the
+garbled-path protection was a silent no-op here.
+
+**Fix:** switched the detector from PCRE (`grep -qaP`) to POSIX ERE (`grep -qaE`), which has no
+such locale restriction, keeping `LC_ALL=C` for byte-wise matching and the **exact same byte set**
+(control chars / `\` / `:` plus the MSYS2 PUA substitutes `0xEE 0x80-0xBF` and `0xEF 0x80-0xA3`).
+Pattern built via `$'...'`. No behavior change other than that it now actually runs.
+
+Verified on BEAST: `bash -n` clean; PUA-garbled name (U+F03A) detected; literal `:` detected;
+normal repo paths not flagged; no `-P` locale error. Applies to all machines on next sync (sync.sh
+is shared).
