 ## [Unreleased]
 
+### Added
+- **Försterkreislauf** (Issue #25):
+  - **Setzlinge beim Fällen**: Jeder gefällte Baum gibt 1–2 `tree_seed` in den Stockpile
+  - **Försterhaus** (`forester_hut`): Neues Gebäude im Build-Menü (Kosten: 50 wood); Log-Hütten-Grafik mit Baum-Symbol; Klick auf das Haus öffnet ein Info-Panel
+  - **Zonenmarkierung**: Im Info-Panel öffnet „Edit Zone" den Zonen-Editor; innerhalb eines Radius von 5 Tiles können Tiles per Klick zur Pflanzzone hinzugefügt oder entfernt werden; markierte Tiles werden als halbtransparente grüne Fläche im Spiel angezeigt; Zone wird im Save gespeichert
+  - **Förster-Job** (`forester`): Nisse mit `forester`-Priorität > 0 pflanzen automatisch `tree_seed` auf leeren Zonen-Tiles; erfordert `tree_seed` im Stockpile
+  - **Chop-Priorisierung**: Beim Fällen werden Bäume innerhalb von Förster-Zonen bevorzugt; natürliche Bäume werden erst gefällt wenn keine Zonen-Bäume mehr vorhanden sind
+  - Nisse-Info-Panel und Nisse-Panel (V) zeigen jetzt auch die `forester`-Priorität als Schaltfläche
+
 ### Fixed
+- **Nisse idle loop** (Issue #22): Nisse no longer retry unreachable trees/rocks in an infinite 1.5 s loop — `pickJob` now skips resources with no adjacent passable tile via `hasAdjacentPassable()`; pathfind-fail cooldown raised to 4 s
+- **Resource-based passability** (Issue #22): FOREST and ROCK terrain tiles are only impassable when a tree/rock resource occupies them — empty forest floor and rocky ground are now walkable; `WorldSystem` maintains an O(1) `resourceTiles` index kept in sync at runtime
+- **Terrain canvas not updating** (Issue #22): `CHANGE_TILE` now calls `refreshTerrainTile()` centrally via the adapter handler, fixing the visual glitch where chopped trees left a dark FOREST-coloured pixel instead of DARK_GRASS
 - **Stockpile panel** (Issue #20): panel background now uses `uiOpacity` and updates live when Settings opacity changes; panel height increased so the Nisse count row no longer overlaps the carrot row
 - **ESC menu** (Issue #20): internal bottom padding corrected — last button now has 16px gap to panel edge instead of 0px

+## Gitea Workflow (repo: tekki/nissefolk)
+
+**Tool:** `tea` CLI (installed at `~/.local/bin/tea`, login `zally` configured).
+Never use raw `curl` with `${CLAUDE_GITEA_TOKEN}` for Gitea — use `tea` instead.
+All `tea` commands run from `~/game` (git remote `gitea` points to the repo).
+
+**Git commands:** Always use `git -C ~/game <cmd>` — never `cd ~/game && git <cmd>` (triggers security prompt).
+
+```bash
+# Create PR (always wait for user approval before merging)
+# Use ~/scripts/create-pr.sh — pass \n literally for newlines, the script expands them via printf.
+# Never use heredocs or $(cat file) — they trigger permission prompts.
+~/scripts/create-pr.sh "PR title" "Fixes #N.\n\n## What changed\n- item one\n- item two" feature/xyz
+
+# List open PRs / issues
+tea pr list --login zally
+tea issue list --login zally
+
+# View a single issue (body + comments)
+tea issue --login zally --repo tekki/nissefolk <ISSUE_NUMBER>
+
+# Merge PR — ONLY after explicit user says "merge it"
+tea pr merge --login zally --style merge <PR_NUMBER>
+
+# Close issue
+tea issue close --login zally --repo tekki/nissefolk <ISSUE_NUMBER>
+
+# List labels
+tea labels list --login zally --repo tekki/nissefolk
+
+# Set/remove labels on an issue (use label names, not IDs)
+tea issue edit --login zally --repo tekki/nissefolk --add-labels "status: done" <N>
+tea issue edit --login zally --repo tekki/nissefolk --remove-labels "status: in discussion" <N>
+
+
+# Both flags can be combined; --add-labels takes precedence over --remove-labels
+tea issue edit <N> --add-labels "status: done" --remove-labels "status: in progress" --repo tekki/nissefolk
+
+# Note: "tea labels" manages label definitions in the repo — not issue assignments
+```
+
+**Label IDs** (repo-specific, don't guess):
+| ID | Name |
+|----|------|
+| 1  | feature |
+| 2  | improvement |
+| 3  | bug |
+| 6  | status: backlog |
+| 8  | status: ready |
+| 9  | status: in progress |
+| 10 | status: review |
+| 11 | status: done |
+
+**PR workflow rules:**
+1. Commit → push branch → `tea pr create` → **share URL, stop, wait for user approval**
+2. Only merge when user explicitly says so
+3. After merge: close issue + set label to `status: done`
+
+**master branch is protected** — direct push is rejected. Always use PRs.
+
+**Routine load issue**
+1. Load Issues
+if-> If the label is status: ready
+    -> work as it says
+    -> use a new branch for each issue
+    -> test your code
+    -> commit your code
+    -> change the issue label
+    -> do an pr to master
+
+if-> If the label is status: discussion
+    -> think if you need more information
+    -> ask questions as comment in gitea
+
+**Issue create**
+If i say something like "create an issue about..." you need to attach the labels to it to. Use status: discussion and feature/bug
