+**Session-cost reality (#2387, measured):** every `codex exec` call — resumed
+or fresh — pays Codex's ~21K-token session prelude (its skill catalogue +
+instructions); `resume` does NOT amortize it (a measured resume came in
+slightly ABOVE a fresh call). Resume buys conversational continuity, never
+token savings. So: prefer ONE codex call per skill where the workflow allows,
+batch questions into that call, and reach for resume only when the follow-up
+genuinely needs the prior session's context.

-# that dirt poisons the stash: the post-upgrade `git stash pop` would
-# restore STALE generated markdown over the fresh checkout permanently.
-# These files are regenerable (setup re-renders brain-aware variants to
-# ~/.gstack/render), so discarding is lossless; anything else the user
-# changed still reaches the stash untouched. Same file classification as

+ in `$INSTALL_DIR`.
+2. If BOTH are empty, the reset is provably safe — run the fallback block
+ below without asking.
+3. Otherwise ask via AskUserQuestion (one-way door — destructive), listing
+ exactly what will be discarded: each dirty file and each unpushed commit
+ by hash + subject. Options: **A)** Discard them and upgrade (reset) —
+ requires the explicit letter; **B)** Abort the upgrade so the user can
+ rescue their work first (recommended when local commits exist). Never
+ proceed on a vague reply.
