+### 2. Grind: #451 + #454 (PRs #451 + #456)
+
+Two issues processed through the grind workflow:
+
+**#451 — `check-worktree.sh` primary checkout detection fix** (PR #451, squash
+`615cd34`): The script used to derive a "primary path" from the script's own
+location and compare it against `git worktree list`, which always matched the
+worktree the caller was standing in — so every worktree commit printed "in the
+primary checkout", and the genuine case (primary checkout left on a feature
+branch) was buried under noise. Fixed by using `git rev-parse --git-common-dir`
+vs `--absolute-git-dir` (identical only in the primary checkout). Also fixed the
+`GREEN` color variable bug that was hidden by the detection bug. 8 real-repo
+tests added. The PR included collateral changes (Caddyfile redirect support, 2
+KB articles) merged together per operator preference.
+
+**#454 — 33 dead global skill symlinks** (PR #456, squash `44d20af`): All 45
+entries in `~/.config/opencode/skills/` were symlinks; 33 pointed into a deleted
+worktree (`opskit-wt-437`), making them dead. Added
+`bin/check-global-skills.sh` — a doctor script that reports broken links
+(`--check`, exit 1 if found) and repoints them to the main checkout (`--fix`).
+The 33 broken symlinks were manually repointed during this session; 0 remain
+broken. 4 tests added.
+
+## Uncommitted work (not mine)
+
+These files are present on main checkout, from other sessions:
+
+- `.opencode/skills/lfnw-linkedin-photo/` (untracked dir)
+- `.tmp/`, `Knoah.md`, `bin/.tmp/`, `worktrees/` (untracked dirs)
+- `argparse`, `json`, `os`, `subprocess`, `sys`, `threading` (untracked files —
+  likely accidental shell redirects from a mangled command)
+- `bin/bwunlock.sh` (modified), `docs/ideas.md` (staged)
+
+Not touched during this session.
