+
+### SICUREZZA: Risultati Operation Obsidian Stress
+
+- **Shield: bypass tramite caratteri Unicode di formato (ZRT-006).** Caratteri
+  Unicode invisibili (ZWJ U+200D, ZWNJ U+200C, ZWSP U+200B) inseriti all'interno
+  di un token potevano eludere il pattern matching. Il normalizzatore ora rimuove
+  tutti i caratteri Unicode di categoria Cf prima della scansione.
+- **Shield: bypass tramite offuscamento con entità HTML (ZRT-006).** I riferimenti
+  a caratteri HTML (`AK` → `AK`) potevano nascondere i prefissi delle
+  credenziali. Il normalizzatore ora decodifica le entità `&#NNN;`/`&#xHH;`
+  tramite `html.unescape()`.
+- **Shield: bypass tramite interleaving di commenti (ZRT-007).** Commenti HTML
+  (`<!-- -->`) e commenti MDX (`{/* */}`) inseriti all'interno di un token
+  potevano interrompere il pattern matching. Il normalizzatore ora rimuove
+  entrambe le forme di commento.
+- **Shield: rilevamento token spezzati tra righe (ZRT-007).** Aggiunto un buffer
+  lookback di 1 riga tramite `scan_lines_with_lookback()` per rilevare segreti
+  suddivisi su due righe consecutive (es. scalari YAML folded). I duplicati sono
+  soppressi tramite il set di tipi già rilevati sulla riga precedente.
+
 ### Aggiunto
 
 - **`--format json` sui comandi di controllo singoli.** `check links`, `check orphans`,

+## [0.6.1rc2] — 2026-04-16 — Obsidian Bastion (Hardened)
+
+### SECURITY: Operation Obsidian Stress Findings
+
+- **Shield: Unicode format character bypass (ZRT-006).** Zero-width Unicode
+  characters (ZWJ U+200D, ZWNJ U+200C, ZWSP U+200B) inserted mid-token could
+  break regex matching. The normalizer now strips all Unicode category Cf
+  characters before scanning.
+- **Shield: HTML entity obfuscation bypass (ZRT-006).** HTML character
+  references (`AK` → `AK`) could hide credential prefixes. The
+  normalizer now decodes `&#NNN;`/`&#xHH;` entities via `html.unescape()`.
+- **Shield: comment-interleaving bypass (ZRT-007).** HTML comments
+  (`<!-- -->`) and MDX comments (`{/* */}`) inserted mid-token could break
+  pattern matching. The normalizer now strips both comment forms.
+- **Shield: cross-line split-token detection (ZRT-007).** Added a 1-line
+  lookback buffer via `scan_lines_with_lookback()` to detect secrets split
+  across two consecutive lines (e.g. YAML folded scalars). Suppresses duplicates
+  via previous-line seen set.
+
 ### Added
 
 - **`--format json` on individual check commands.** `check links`, `check orphans`,

 ## Security & Compliance
 
 - **Security First:** Any new path resolution MUST be tested against Path Traversal. Use `PathTraversal` logic from `core`.
+- **Shield Obfuscation Tests:** Every new Shield pattern or normalizer rule MUST include obfuscation regression tests: Unicode format characters (category Cf), HTML entity encoding, comment interleaving (HTML `<!-- -->` and MDX `{/* */}`), and cross-line split tokens. See `tests/test_shield_obfuscation.py` for reference.
 - **Bilingual Parity:** Documentation lives in [zenzic-doc](https://github.com/PythonWoods/zenzic-doc). Refer documentation contributors there.
