+# 2026-07-10 — Save-version claim correction
+
+```
+Type: log
+```
+
+## Intent
+
+Tick check found a contradiction: `wiki/mechanics/sim-mechanics.md` still
+said the save format was “currently 21,” while `crates/misaligned-core/src/save.rs`
+declares `SAVE_VERSION = 22` and `wiki/engineering/current-build.md` states the
+build is live on v22.
+
+## Correction
+
+- `wiki/mechanics/sim-mechanics.md`: updated the save format sentence in the
+  “Save format” section from “currently 21” to “currently 22.”
+
+## Checks
+
+- `tools/ledger_index.sh`
+- `git diff --check`
+- `./tools/check.sh --docs`
+
+## Impact
+
+Knowledge wording updated only; no code, tooling, or gameplay behavior changed.
