+/**
+ * Branch-name slug hygiene in file-path positions (#2550, #1851/#1127).
+ *
+ * gstack-review-log WRITES `<canonical-branch>-reviews.jsonl` where the
+ * canonical form comes from bin/gstack-slug (tr '/' '-' then
+ * tr -cd 'a-zA-Z0-9._-'). Context Recovery used to PROBE the same file with
+ * raw $_BRANCH (`git branch --show-current`) — so for any branch containing
+ * a `/` (most feature branches) the REVIEWS line never fired. Same class:
+ * review.ts's plan content-search sanitized with tr '/' '-' only, missing
+ * the tr -cd half of the canonical pipeline.
+ *
+ * Discipline pinned here:
+ *   - FILE-PATH positions interpolate the slug-canonical $BRANCH (set by the
+ *     gstack-slug eval that opens Context Recovery).
+ *   - Raw $_BRANCH stays for display (BRANCH: echo) and for timeline.jsonl
+ *     content greps — the timeline writer stores the RAW branch, so slugging
+ *     the reader would break that pairing.
+ *
+ * Reader-side fix folded from community PR #1851 by @harjothkhara.
