+# itzg/minecraft-server — Custom Plugin Jar Persistence
+
+**Date:** 2026-05-07
+**Context:** `ChatChat-1.0.0-SNAPSHOT-racked-1.jar` was dropped manually into `/data/plugins/` and disappeared after the next container restart.
+
+---
+
+## 1. Why the ChatChat jar disappeared
+
+itzg's entrypoint runs this sequence on every start (when `REMOVE_OLD_MODS=TRUE`):
+
+1. **Wipe** — every file in `/data/plugins/` matching `REMOVE_OLD_MODS_INCLUDE` and not matching `REMOVE_OLD_MODS_EXCLUDE` is deleted.
+2. **Download** — every URL in `PLUGINS` and every Modrinth project in `MODRINTH_PROJECTS` is fetched into `/data/plugins/`.
+3. **Copy** — anything listed in `COPY_PLUGINS_SRC` (or container paths inside `PLUGINS`) is rsynced in.
+
+Our current compose has:
+
+```yaml
+REMOVE_OLD_MODS: "true"
+REMOVE_OLD_MODS_INCLUDE: "*.jar"
+REMOVE_OLD_MODS_EXCLUDE: "AuthLimbo*.jar"
+```
+
+So step 1 deletes **every** `*.jar` except `AuthLimbo*.jar`. The hand-placed ChatChat jar was not in any download list and not in the exclude glob, so it was nuked and never re-downloaded. AuthLimbo survives only because we explicitly excluded it.
+
+This is documented behaviour, not a bug — itzg's design assumes plugins are declarative, sourced from URLs/Modrinth/`COPY_PLUGINS_SRC`, never hand-dropped.
+
+## 2. Three mechanisms to make custom jars persist
+
+| # | Mechanism | How |
+|---|-----------|-----|
+| A | **`REMOVE_OLD_MODS_EXCLUDE` glob** | Add `ChatChat*.jar` to the exclude list. Quick but fragile — depends on filename and only protects already-present files; doesn't handle re-deploy on a fresh volume. |
+| B | **`COPY_PLUGINS_SRC` bind-mount** | Mount a host dir of custom jars read-only at e.g. `/plugins-custom`, set `COPY_PLUGINS_SRC=/plugins-custom`. Entrypoint copies them in after the wipe. Survives wipes, version-controllable, declarative. |
+| C | **`PLUGINS` URL → Forgejo Release** | Upload the jar as a Forgejo Release asset, add the download URL to the existing `PLUGINS` list. Same flow as EssentialsX/spark already use. |
+
+Note: `PLUGINS` also accepts container paths directly (e.g. `PLUGINS=/plugins-custom/ChatChat.jar`), so mechanism B can collapse into the existing `PLUGINS` env if preferred.
+
+## 3. Recommended path for racked.ru — Mechanism B
+
+`COPY_PLUGINS_SRC` is the cleanest fit:
+- Custom jars live in the repo (or `/opt/docker/minecraft-custom-plugins/`), so they're under version control / backup.
+- No external host dependency (Forgejo could be down — bind mount can't be).
+- Build artefacts from `staging/chatchat/` drop straight into the mounted dir.
+
+### docker-compose.yml diff
+
+```diff
+       MODRINTH_LOADER: paper
+       SPIGET_RESOURCES: ""
+       REMOVE_OLD_MODS: "true"
+       REMOVE_OLD_MODS_INCLUDE: "*.jar"
+-      REMOVE_OLD_MODS_EXCLUDE: "AuthLimbo*.jar"
++      REMOVE_OLD_MODS_EXCLUDE: "AuthLimbo*.jar,ChatChat*.jar"
++      COPY_PLUGINS_SRC: "/plugins-custom"
+     volumes:
+       - /opt/docker/minecraft:/data
++      - /opt/docker/minecraft-custom-plugins:/plugins-custom:ro
+```
+
+Then on the host:
+
+```bash
+sudo mkdir -p /opt/docker/minecraft-custom-plugins
+sudo cp staging/chatchat/ChatChat-1.0.0-SNAPSHOT-racked-1.jar \
+        /opt/docker/minecraft-custom-plugins/
+sudo cp /opt/docker/minecraft/plugins/AuthLimbo-*.jar \
+        /opt/docker/minecraft-custom-plugins/   # optional: source-of-truth
+sudo chown -R 1000:1000 /opt/docker/minecraft-custom-plugins
+docker compose up -d --force-recreate mc
+```
+
+The `EXCLUDE` line still lists `ChatChat*.jar` so that if the bind mount ever vanishes, an existing copy in `/data/plugins/` isn't wiped — belt and braces.
+
+## 4. Bonus — Forgejo Release upload procedure (mechanism C)
+
+If you'd rather host the jar at `git.s8n.ru` (e.g. for cobblestone or a friend's box without the bind mount):
+
+```bash
+# 1. Tag and push
+cd staging/chatchat
+git tag -a chatchat-racked-1 -m "ChatChat racked build 1"
+git push origin chatchat-racked-1
+
+# 2. Create release + upload asset (uses Forgejo PAT from ~/.config/veilor-forgejo)
+TOKEN=$(cat ~/.config/veilor-forgejo/pat)
+curl -X POST \
+  -H "Authorization: token $TOKEN" \
+  -H "Content-Type: application/json" \
+  https://git.s8n.ru/api/v1/repos/s8n/minecraft-server/releases \
+  -d '{"tag_name":"chatchat-racked-1","name":"ChatChat racked-1","draft":false}'
+
+RELEASE_ID=$(curl -s -H "Authorization: token $TOKEN" \
+  https://git.s8n.ru/api/v1/repos/s8n/minecraft-server/releases/tags/chatchat-racked-1 \
+  | jq -r .id)
+
+curl -X POST \
+  -H "Authorization: token $TOKEN" \
+  -H "Content-Type: application/java-archive" \
+  --data-binary @ChatChat-1.0.0-SNAPSHOT-racked-1.jar \
+  "https://git.s8n.ru/api/v1/repos/s8n/minecraft-server/releases/$RELEASE_ID/assets?name=ChatChat-1.0.0-SNAPSHOT-racked-1.jar"
+```
+
+Then add to compose:
+
+```yaml
+PLUGINS: |
+  ...existing...
+  https://git.s8n.ru/s8n/minecraft-server/releases/download/chatchat-racked-1/ChatChat-1.0.0-SNAPSHOT-racked-1.jar

+# Migration Plan — EZShop + Kiranhart AH → ExcellentShop unified
+
+**Date:** 2026-05-08
+**Author:** s8n
+**Supersedes:** AUDIT-2026-05-07 F-11; SHOP-SYSTEM-DECISION sec. 6 (now operational)
+**Staging:** `staging/excellentshop/`
+**Status:** Ready for operator-scheduled maintenance window.
+
+---
+
+## 1. Summary
+
+Replace two plugins (EZShop 1.0-SNAPSHOT bespoke + Kiranhart AuctionHouse
+1.4.6 ARR-no-LICENSE) with one GPL-3 stack:
+ExcellentShop 5.0.1 + CoinsEngine 2.7.0, both built by NightExpress against
+nightcore 2.15.3. All three jars are sourced from the upstream Reposilite
+(`repo.nightexpressdev.com`) — source-of-truth identical to a local
+`mvn package` from `github.com/nulli0n/ExcellentShop-spigot`, just reproducible
+without the brittle `alex9849` integration that fails on TLS handshake.
+
+Both modules share one theme, one perm tree, one update cadence. Chest Shop
+module is disabled — not a future-of-server commit (QuickShop-Hikari path
+already documented in SHOP-SYSTEM-DECISION).
+
+## 2. Pre-flight (not in `swap.sh`, do these first)
+
+1. **Heads-up window:** post in-game notice via `/pm news` minus 7d, 1d, 1h.
+   "Auction listings will be drained on YYYY-MM-DD HH:MM."
+2. **Drain Kiranhart AH:** instruct players to claim/cancel listings.
+   Bid-in-progress items revert at the close of the bid window (max 2h,
+   per `bid-auction-duration: 7200`). Manual refund the residue to the
+   listing owner via `/eco give` after the window — record the audit
+   trail in `live-server/migration-2026-05-08-residue.log`.
+3. **Snapshot live data:** invoke
+   `scripts/restic-backup-playerdata.sh` (already wired for nullstone).
+   Verify the snapshot via `restic snapshots --tag pre-shop-migration`.
+4. **Verify staged bundle:**
+   ```
+   cd staging/excellentshop/build
+   sha256sum *.jar          # match the values committed alongside this doc
+   ```
+5. **Confirm operator window:** compose stop → up takes ~3 minutes;
+   ExcellentShop generates ~11 default shops + 400 items on first start
+   (~30s extra). Total expected downtime: 4-6 minutes best case,
+   12 minutes worst case (if itzg downloads stall).
+
+## 3. Swap procedure
+
+`scripts/swap.sh` runs as `user@nullstone` and performs:
+
+| Step | Action |
+|------|--------|
+| 1 | `docker compose stop mc` |
+| 2 | tar legacy `EZShop` + `AuctionHouse` plugin trees + jars to `/opt/docker/minecraft/plugins.tar.bak-<ts>` |
+| 3 | privileged `rm -rf` of legacy trees and jars (uses `docker run --privileged --userns=host` per `feedback_docker_sudo_bypass`) |
+| 4 | populate `/opt/docker/minecraft-custom-plugins/` with the three staged jars, chown 1000:1000 |
+| 5 | replace `docker-compose.yml` with `docker-compose.patch.yml` (adds `COPY_PLUGINS_SRC=/plugins-custom`, the bind mount, and the new `REMOVE_OLD_MODS_EXCLUDE` glob list) — keeps a `.bak-<ts>` |
+| 6 | `docker compose up -d mc` (first-start config generation runs here) |
+| 7 | poll `mc-health` for up to 4 minutes |
+| 8 | `docker cp` the staged config overrides into the now-populated plugin tree, run `excellentshop reload` + `coinsengine reload`, then run `lp-shop-migration.sh` over RCON to grant default-tier perms |
+
+The compose patch is identical to the existing live compose **except** for
+the three lines: `PLUGINS` (drops EZShop+AH URLs), `REMOVE_OLD_MODS_EXCLUDE`
+(adds three new globs), and `COPY_PLUGINS_SRC` + matching volume mount.
+
+## 4. Smoke test (post-swap, manual)
+
+Run as a non-staff player and as a staff player:
+
+- `/shop` → main category menu, 11 shops, GUI renders within 1s.
+- `/sellall` → sells inventory, `+N coins` chat feedback, `/balance` updates.
+- `/sellhand` → sells hand stack, hand cleared.
+- `/ah` → AH GUI opens, list a test item via `/ah list 100`, see it in browse.
+- `/ah` admin: `/ah admin remove <listing>` works, `/ah admin expire` works.
+- `/balance`, `/pay`, `/eco` resolve through CoinsEngine via Vault bridge.
+- Tail logs `docker logs -f minecraft-mc | grep -E 'nightcore|ExcellentShop|CoinsEngine|ERROR|WARN'` for 5 minutes after first player joins.
+
+If any of the above fail, run `scripts/rollback.sh`.
+
+## 5. Rollback
+
+`scripts/rollback.sh` reverses everything: stops the container, removes
+ExcellentShop+CoinsEngine+nightcore plugin trees and jars, clears the
+custom-plugins bind dir, restores legacy `EZShop`+`AuctionHouse` from the
+tar snapshot, restores the previous `docker-compose.yml`, restarts, and
+runs `lp-shop-rollback.sh` over RCON to restore the legacy perm nodes.
+
+Rollback total time: ~5 minutes.
+
+## 6. Risk register
+
+| # | Risk | Likelihood | Impact | Mitigation |
+|---|------|-----------|--------|-----------|
+| R1 | nightcore 2.15.3 incompatible with Purpur 1.21.11 (api-version 1.21 should match) | Low | High | Smoke-test on a throwaway container first; rollback path < 5 min if breakage |
+| R2 | CoinsEngine 2.7.0 fails Vault bridge (EssentialsX expects Vault) | Medium | High | `Vault_Compatibility.Default: true` set in staged currency YAML; verify `/balance` in smoke step 4 |
+| R3 | NightExpress reposilite goes dark before next maintenance | Low | Low | Jars are committed to the repo at `staging/excellentshop/build/` with sha256 receipts — never re-fetched at swap time |
+| R4 | Players keep typing `/auctionhouse` (legacy alias) | Certain | Low | `commands.yml` aliases `[ah, auctionhouse, market]` keep muscle memory |
+| R5 | EZShop balance migration loss (if EZShop tracked any) | Very Low | Low | EZShop was sell-only with Vault → balances live in EssentialsX, untouched by this swap |
+| R6 | Live AH listings lost (residual stuck items) | Medium | Medium | Pre-flight step 2 drains, residue refund is documented |
+| R7 | First-start delay > 4 min healthcheck window (large default catalog generation) | Low | Medium | `start_period: 240s` already set; if exceeded, manual `docker exec mc mc-health` poll |
+| R8 | Compose typo locks server out of plugins | Low | High | `swap.sh` keeps `docker-compose.yml.bak-<ts>` for trivial revert; rollback restores it |
+| R9 | `excellentshop.shop.use` not granted to default group → no players can `/shop` | Medium | High | `lp-shop-migration.sh` step 8 grants the full perm tree; verify with `/lp user <name> permission check excellentshop.shop.use` |
+| R10 | Compose `cap_drop: ALL` strips a cap CoinsEngine needs | Low | Low | If `/data/plugins/CoinsEngine/` write fails, `cap_add: DAC_OVERRIDE` rescue documented in swap.sh comments |
+
+## 7. Top 3 swap-window risks (operator brief)
+
+1. **R9 (perm regression)** — if the LP migration RCON call drops mid-script,
+   players see `/shop` work but `/sellall` fail. Mitigation: re-run
+   `lp-shop-migration.sh` idempotently — every line is `permission set <node> true`.
+2. **R7 (slow first-start)** — first start of a fresh ExcellentShop with the
+   bundled catalog generation takes ~30s extra and might trip the 240s
+   healthcheck on a cold pool. Mitigation: `swap.sh` step 7 polls manually
+   before declaring success.
+3. **R2 (Vault bridge)** — if `/balance` returns 0 instead of the player's
+   actual balance, the Vault bridge from CoinsEngine is mis-wired. Mitigation:
+   `Vault_Compatibility.Default: true` is in the staged YAML; if still broken,
+   `/eco give <player> <prev-balance>` from the EssentialsX-side dump that
+   `restic-backup-playerdata.sh` already takes.
+
+## 8. Estimated downtime
+
+- **Best case:** 4 minutes (compose stop → up + health check, no log churn).
+- **Typical:** 6 minutes (one extra stall on jar copy or LP RCON timeout).
+- **Worst case:** 12 minutes (first-start catalog generation slow + manual smoke).
+
+If the worst case is exceeded, abort and run `rollback.sh` — the data
+snapshot from pre-flight step 3 is the source of truth.
+
+## 9. Post-migration
+
+- Update `AUDIT-2026-05-07.md` F-11: status → Resolved (date 2026-05-08).
+- Update `docs/COMMANDS.md`: `/shop`, `/ah`, `/sellall`, `/sellhand`,
+  `/balance` all now route through ExcellentShop+CoinsEngine.
+- Update `SYSTEM.md` plugin table: drop EZShop, drop AuctionHouse 1.4.6,
+  add ExcellentShop 5.0.1, CoinsEngine 2.7.0, nightcore 2.15.3.
+- Schedule a follow-up audit in 7d to confirm no log spam, no economy
+  drift, no listing exploits.

+# ExcellentShop / CoinsEngine Configs (Staged)
+
+This directory holds **post-first-run** configuration overrides for the migration.
+
+## How it works
+
+ExcellentShop and CoinsEngine generate their own opinionated default
+configs the first time the plugin starts. Those defaults are excellent
+out of the box — 11 themed virtual shops with ~400 vanilla items, sane
+buy/sell prices, polished GUIs.
+
+Rather than ship a hand-translated EZShop catalog (which would be a
+strict regression — EZShop only had ~80 items, sell-only), this
+migration **adopts the bundled ExcellentShop catalog** and lays down
+a small set of **operator-tunable overrides** on top.
+
+The bundled catalog already covers the eight EZShop categories the
+operator listed: building blocks, colored blocks, food, mob drops,
+miscellaneous, minerals, redstone, farming, decoration, plus
+combat/tools and potions.
+
+## Files in this dir
+
+- `apply-overrides.sh` — runs after first start, patches the 11 generated shop YAMLs to apply the racked.ru tweaks listed below.
+- `coinsengine/config.yml` — pre-staged, drops in the single `coin` currency named "coins" (matches the EZShop messages).
+- `coinsengine/currencies/coin.yml` — currency definition.
+- `excellentshop/config.yml` — top-level plugin overrides (modules: virtual=on, auction=on, chest=OFF).
+- `excellentshop/modules/virtual_shop/config.yml` — `/shop` alias, sell-all, sell-hand commands, no rank multiplier (we keep parity with EZShop's flat pricing).
+- `excellentshop/modules/auction/config.yml` — Kiranhart-equivalent settings: 1% tax, BIN+bid, 10 listings default, 7200s bid duration, 172800s BIN duration.
+
+## What's NOT staged
+
+- Per-item prices — bundled defaults are kept. If the operator wants to align specific items to legacy EZShop prices, edit the generated `plugins/ExcellentShop/modules/virtual_shop/shops/<id>/config.yml` files and adjust `sell` / `sellAll` price fields. EZShop legacy table preserved at `legacy-ezshop-prices.yml` for reference.
+- `legacy-ezshop-prices.yml` — full export of EZShop's `item-prices` map; reference only.
+
+## Layout reference (54-slot per category from YOU500 ask)
+
+Bundled shops are 54-slot (6 rows) by default with category icons in the
+main menu, exactly the layout described in `SHOP-SYSTEM-DECISION.md`.
+The operator does NOT need to manually configure 54-slot — it's the default.
