-This release contains two narrowly scoped corrections discovered while
-validating all public Phase 1 query constraints against the static inventory.
+## Canonical cuisine policy
 
-## Shanghai cuisine label
+The canonical executable Chinese cuisine value for the 66 corresponding
+Shanghai restaurant rows is `本帮菜`. The English rows continue to use
+`Shanghai cuisine`.
 
-The English Shanghai restaurant table consistently used `Shanghai cuisine`,
-while the corresponding 66 Chinese rows used `本帮菜` and some public DSL used
-`上海菜`. The Chinese executable label is now canonicalized to `上海菜`; natural
-user prose may still use “本帮菜”. No restaurant names, prices, coordinates,
-hours, or recommended dishes changed.
+Natural-language queries are intentionally not normalized: expressions such
+as “上海菜”, “本帮菜”, “上海特色美食”, and “当地特色菜” remain valid linguistic
+variants. Only the executable DSL and sandbox values are canonicalized.
 
-## Fuchun cruise operating interval
+Release `2026.08.1` briefly changed these 66 Chinese values to `上海菜`.
+Release `2026.08.2` restores them to `本帮菜`. No restaurant name, price,
+coordinate, opening hour, recommendation, or other field changed.
 
-Attraction row `id=198` in Hangzhou declared a recommended visit duration of
-3.0–3.5 hours but an operating interval of only `14:00–15:00`. Its closing time
-is now `18:00` in both languages:
+## Retained Fuchun cruise repair
+
+The corrected closing time for attraction row `id=198` remains `18:00` in
+both languages, allowing its published 3.0–3.5 hour recommended visit duration
+to fit inside the `14:00–18:00` operating interval:
 
 - `富春山居号游船`
 - `Fuchun Mountain Residence Cruise`
 
-No other attraction field changed.

 ## Validation
 
+- Compared with `2026.08.1`, exactly one Chinese source file differs.
+- Exactly 66 rows differ, and `cuisine` is the only changed field.
+- All 132 English source files are byte-identical to `2026.08.1`.
 - Chinese and English source layouts remain parallel at 132 files each.
-- All normalized bilingual table row counts remain equal.
-- Parquet round trips passed for all 14 language/table outputs.
-- Raw ZIP archives contain the corrected evaluator-compatible databases.
-- All files are covered by per-language checksums and the root release
-  manifest.
+- All 14 Parquet outputs passed round-trip validation.
