+## [v0.9.5] - JSON Stabilization - April 18, 2026
+
+### 🧩 JSON Parser & Serializer Fixes
+- Fixed JSON text parsing to correctly handle valid quoted strings and escape sequences without falling into false `unterminated text` errors.
+- Hardened object key/value handling for empty-object paths in `JsonValue.set(...)`, `JsonValue.has(...)`, and `JsonValue.getKey(...)`.
+- Corrected unicode `\uXXXX` formatting internals in JSON serialization to avoid type/runtime mismatches in escape generation.
+- Fixed JSON text escaping so regular letters (such as `b` / `f`) are preserved and only real control characters are escaped.
+
+### 🧪 Validation & Coverage
+- Restored full `JsonStandardLibraryComprehensive.cod` assertions (text, object, round-trip, unicode, invalid-case coverage).
+- Verified direct `CommandRunner` execution for the JSON comprehensive suite now passes.
+- Re-validated demo parity suite (`CodPTACParityRunner`) after JSON fixes.
+
## [v0.9.2] - Why Slow? - April 17, 2026

Current demo validation status from `src/main/cod/demo/src/main/test`:
-- `CodP-TAC parity runner` (`cod.runner.CodPTACParityRunner`, excluding `*Invalid*.cod`): **48/48 passed**.
-- `LazyLoop.cod` parity: **passed**.
-- Direct `CommandRunner` scans (same non-invalid set) highlight remaining runtime limitations:
- - `LazyLoop.cod` previously hit a stack overflow error during conditional-formula-style parity value reads. This update fixes the runtime recursion issue without changing demo behavior.
- - `ConditionalFormulaOptimization.cod` can still trigger a stack overflow error.
- - Input-driven demos (`Interactive.cod`, `IO.cod`, `Parity.cod`) fail without real stdin values.
- - `HelloWorld.cod`, `JsonStandardLibraryComprehensive.cod`, `OOPConstructor.cod`, `SuperThis.cod`, and `test/unsafe/*` currently expose parser/runtime issues when executed directly via `CommandRunner`.
+- `CodP-TAC parity runner` (`cod.runner.CodPTACParityRunner`, excluding `*Invalid*.cod`): **56/56 passed**.
+- Direct `CommandRunner` sweep for non-invalid demos: **49/49 passed** (with required stdin fixtures for input-driven demos such as `Interactive.cod`, `IO.cod`, and `Parity.cod`).
+- `JsonStandardLibraryComprehensive.cod` now runs successfully in direct `CommandRunner` mode with full text/object/unicode/invalid-case assertions enabled.
Checked invalid demos (`*Invalid*.cod`) confirm currently unsupported/invalid patterns:
