+## Plan
+
+> Anchor: design `specs/2026-06-11-design-handoff-design.md` (v1.0.0, graduated) · §7.2 SLICE-3
+> Anchor issues: #95 (storage/linkage — link step), #93 (spec field) · Eligibility: R2a (graduated Solution Design) — eligible, no override
+> Worktree: `.claude/worktrees/session-0072-design-handoff-slice3` (branch `worktree-session-0072-design-handoff-slice3`) — isolated; ≥1 concurrent --INPROGRESS placeholder in flight
+
+SLICE-3 — the **link step** of `wgl-design-handoff` (PUC-1, PP-3): an idempotent
+issue-body-upsert that writes a canonical `**Designs:** <path>` pointer line into
+the tracking Gitea issue, so a homed bundle (SLICE-2) is discoverable from its
+ticket. Independent of SLICE-2/SLICE-4. Offline + fixture-tested (§6.8).
+
+Deliverables (bottom-up, TDD):
+
+1. **`gitea-api.sh` extension** (§6.2/§6.4 — helper lives *in* gitea-api.sh):
+   - `upsert-body-line --label L --value V` — **PURE** transform: reads a body on
+     stdin, emits the body with the labelled line inserted/replaced/deduped on
+     stdout. No token, no network — the testable core carrying all INV-2 logic.
+   - `issue-body-upsert [--token-service S] <host> <repo> <issue> --label L --value V [--dry-run]`
+     — network glue: GET issue body → run the pure transform → **no-op if
+     unchanged**, else PATCH `{body}`. Idempotency decision = `new == old`.
+   - Legacy `<host> <METHOD> <path>` passthrough untouched (30+ callers).
+2. **Thin caller** `skills/wgl-design-handoff/scripts/link-design-issue.sh`
+   (modelled on `set-patchwatch-status.sh`): `--issue N --design PATH [--repo o/n]
+   [--host h] [--dir D] [--dry-run]`; resolves repo/host from git origin; token
+   `WGL_DESIGN_HANDOFF_TOKEN_SERVICE` (default `wgl-gitea-issues-readwrite-token`,
+   INV-5); hardcodes label `**Designs:**`; delegates to `issue-body-upsert`.
+3. **Test** `test-design-issue-link.sh` (offline, hermetic):
+   A. pure transform vs fixture bodies — insert / replace / no-op-identical /
+      dedup-multiple / empty-body / preserve-other-lines / path with slashes.
+   B. thin caller vs stubbed `CLAUDE_PLUGIN_ROOT`/fake `gitea-api.sh` (test-typecheck
+      pattern) — correct delegation (label/issue/value), git-origin repo
+      resolution, --dry-run, usage errors.
+   C. `issue-body-upsert` integration vs fake `curl`+`security` on PATH — GET
+      fixture body → PATCH-when-changed, **no PATCH when unchanged** (INV-2 at the
+      API layer).
+4. **Docs + ship:** TOKENS.md `WGL_DESIGN_HANDOFF_TOKEN_SERVICE` row; bump
+   `plugin.json` 0.53.0 → 0.54.0; `scripts/lint.sh --check-bump`; PR; merge.
+
+Pipeline (§9): no deployable runtime surface (plugin scripts only) → DoD = unit
+tests + lint green, merged to `main`, version bumped. Live next session after
+re-install (`update-plugin.sh` at finalize).
