-## Why 300 tags?
+## Why 304 tags?
 
 The project convention is one `v3-*` tag per green step across all
 sessions (two-phase parse slices, generics increments, Unicode, stdlib,
 …).  They are a searchable history of passing states, not branches.
-`git tag --list | wc -l` = 300 is expected; only the recent ones above

 ## Current state
 
-- `master` = `6b2df4c` + docs, **ahead** of `origin/master` (`2d1c658`).
-- `v3-rangechecks`, `v3-packedset` and the 2026-10-23 session tags are
-  local; push them with `master` when ready.
+- `master` = `96a3080` + this map, **5 commits ahead** of
+  `origin/master` (`2a30d8c`).
+- `v3-exceptions` and `v3-session-2026-10-23-exceptions-end` are local;
+  push them with `master` when ready.  Earlier PACKEDSET/history tags
+  are already on the remote.
 - Next session: start from `master` and read
   `docs/handoff-2026-10-23-next.md`.
