+The index tracks the repo automatically, from the only moment the corpus actually changes — a
+successful pull. `git_pull_execute.sh` re-indexes behind three gates: the pull succeeded and
+changed tracked files, `AI_INDEX_ON_PULL=true`, and `AI_ENABLED=true`. It is never fatal — a
+failed index leaves the previous one in place and the pull still reports success.

-`AI_INDEX_ON_PULL` exists in `master.conf` as the intended gate for wiring this into
-`git_pull_execute.sh` directly. It is not yet consumed by anything — the variable is reserved,
-not live.
+No cron entry and no `DAILY_MAINTENANCE_SCRIPTS` line are needed; the daily pull carries it.
 
 An incremental run on an unchanged repo is ~70 ms, so a daily entry costs effectively nothing
 and a pull that changed twelve files costs a few seconds.
