+## Update 2026-10-15: decomp advanced to 8a174cb
+
+Vendored checkout moved from `aca4f59` to **`8a174cb`**, 18 commits ahead
+(`origin/master`). All 18 are `src/game` function-matching work; **no header,
+doc, config or `config/levels/functions.tsv` changes**, so the function extents and
+level catalogue this project uses are unaffected.
+
+What is new and usable: **14 of the newly matched functions fall inside the
+overlay `.text`** (`0x2a3b80`-`0x447900`), so they are decomp addresses verified
+against the same code this project runs:
+
+    002A7750 002AA800 002B3868 002B6120 002B7E28 002C7748 002CD8C0
+    002D5E98 002DDEC8 002DF1B8 002E7018 002F5220 002FC8D0 00300618
+
+None of them is camera, frustum or GS code -- the bodies are game logic and
+toolchain-status material. Recorded because matched-in-overlay addresses are the
+thing `PROVENANCE.md` says is reliable here, and `20655c7` needs exactly that kind
+of anchor to follow `UpdateCamera_6` from `lvl.camvtbl`.
