 **`gstack-context-bill` now bills a real install.** On `~/.claude/skills` it reported "2 skills, ~134 tok" always-on, because setup installs each skill as a real directory whose `SKILL.md` and `sections/` are symlinks into the gstack checkout, and the walker only counted regular files. The tool built to answer the token-cost complaint gave a falsely tiny answer on the layout users actually have. On a fresh install it now reports 58 skills, ~6.8K tokens always-on, and 3.6 MB on disk (it was 37 KB across 2 skills). Billing the checkout itself is unchanged (66 skills, ~7.2K tokens).
 
 ### Fixed
-- **`lib/context-bill.ts`**: `findSkillDirs`, `walkMd` and the foreign-file check follow symlinked files and directories. Every path the bill reports, and every file `--exact` keys on, stays the lexical path under the root you passed. Each real directory is walked once (cycle guard), and a link to a directory that contains the tree being walked (`..`, `/`, `$HOME`) is never followed, so a link cannot pull a sibling skill or your home directory into the bill. `walkMd` skips a child repo checkout (the `gstack/` link beside the installed skills), as `findSkillDirs` already did, so `--exact` does not send the whole checkout.
+- **`lib/context-bill.ts`**: `findSkillDirs`, `walkMd` and the foreign-file check follow symlinked files and directories. Every path the bill reports, and every file `--exact` keys on, stays the lexical path under the root you passed. A directory already on the current walk (a loop) is never re-entered, and a link to a directory that contains the tree being walked (`..`, `/`, `$HOME`) is never followed, so a link cannot pull a sibling skill or your home directory into the bill. Two links to one directory are both walked, as two links to one skill already were, so the result never depends on directory listing order. `walkMd` skips a child repo checkout (the `gstack/` link beside the installed skills), as `findSkillDirs` already did, so `--exact` does not send the whole checkout.
 
 ### Tests
 - `test/context-bill.test.ts`: an installed-layout fixture (a checkout outside the skills root, real skill directories with symlinked `SKILL.md` and `sections/`, and a `gstack/` link to the checkout) bills both skills with the target's exact frontmatter, `SKILL.md` and section bytes, and keeps every walked path under the root. Negative controls: a dangling `SKILL.md` link and a `SKILL.md` link to a directory are not skills. A second fixture holds a self link, a parent link that reaches a skill outside the root, a loop back into the skill and a link up to the temp root; only the one real skill and its own files are billed. Both cases fail on main (the first finds no skills, the second bills the outside skill).
