/**
* Regression pin: `gstack-memory-ingest` must pass `--include-gitignored` to
* `gbrain import`.
*
* gstack-artifacts-init writes an ignore-everything `.gitignore` (a bare `*`,
* headed "Do not edit") at the root of `~/.gstack`. The memory ingest stages
* pages into `~/.gstack/.staging-ingest-<pid>-<ts>/`, which is INSIDE that
* repo, and gbrain's markdown collector honours .gitignore. So the collector
* walks the staging dir, matches every file against `*`, and collects zero.
*
* The failure is silent: `gbrain import` exits 0 having imported nothing,
* while the ingest still prints `written: N` from the STAGED count rather
* than the imported count. A run that indexes nothing is indistinguishable
* from a healthy one, and the memory corpus quietly stops growing.
*
* Two tests here:
* 1. Source pin (same shape as memory-ingest-no-put_page.test.ts): the flag
* is present in active code, so removing it trips the build.
* 2. Behavioural proof of the underlying collision, using git's own ignore
* machinery. No gbrain and no network required.
