-# OpenCloud All-in-One Docker Container
+# CasjaysDev Docker Application Image Specification (casjaysdevdocker)
 
-## Overview
+**Name**: {name}
 
-This is a comprehensive all-in-one Docker container for OpenCloud, a Go-based file sync and share platform (successor to ownCloud). The container includes all integrated services required for a full-featured deployment.
+**About this file:** This is the complete, authoritative specification for a CasjaysDev
+Docker **application image** repository (`casjaysdevdocker/{name}`). It is a master
+template — copied into an app image repo as that repo's `AI.md`. It is **permanent** —
+never delete it from a repo that carries it.
 
-## Included Services
+**Note:** `{name}` in this file is a reference token, not setup-time replacement text. Its
+value is always the repo directory basename (`basename "$PWD"`).
 
-| Service | Port | Purpose |
-|---------|------|---------|
-| ClamAV | Socket | Antivirus scanning for uploaded files |
-| Apache Tika | 9998 | Full-text search and document extraction |
-| Radicale | 5232 | CalDAV/CardDAV for Calendar and Contacts |
-| Collabora CODE | 9980 | Document collaboration (LibreOffice Online) |
-| OpenCloud | 9200 | Core file sync/share platform |
-| Nginx | 80 | Reverse proxy (external-facing) |
+**Maintenance procedure:** The bootstrap/update runbook (regenerating files after upstream
+template changes, creating new repos) is NOT in this file — it lives in the
+`dockersrc-bootstrap` agent (it handles both repo families via `REPO_TYPE` detection).
+This file defines the standards that procedure enforces.

+
+# PART 0: CRITICAL RULES
+
+## Org mapping
+
+| System | Org | Example |
+|--------|-----|---------|
+| GitHub (source) | `casjaysdevdocker` | `https://github.com/casjaysdevdocker/{name}` |
+| Docker Hub (push) | `casjaysdevdocker` | `casjaysdevdocker/{name}` |
+
+`casjaysdevdocker` repos are **applications** (gitea, opengist, super-productivity,
+ampache, aria2, …). They always build FROM the pre-built, multi-arch `casjaysdev/*` base
+images — never directly from upstream distro images. The bases themselves live in the
+separate `dockersrc` org (GitHub `dockersrc/{base}` → Docker Hub `casjaysdev/{base}`) —
+see the base specification (`DOCKERSRC.md`).
+
+## Non-negotiable rules
+
+1. **`AI.md` is permanent** — never delete it from the repo.
+2. **Generated files are owned by the template system** — never hand-tune content that
+   `gen-dockerfile` regenerates (see PART 1 ownership table); fix the upstream
+   `gen-dockerfile` template instead, then regenerate.
+3. **Hand-crafted files are owned by the repo** — `gen-dockerfile` must never overwrite
+   app-specific init.d scripts, custom bin scripts, a `05-custom.sh` with real content, or
+   a hand-crafted README (PART 6).
+4. **Removed OCI labels stay removed** (PART 2) — never re-add `base.name`,
+   `schema-version`, or duplicate `authors`/`source` entries.
+5. **`image.url` is a browsable page** — `https://hub.docker.com/r/casjaysdevdocker/{name}`.
+   `docker.io` is only a registry pull host; it is never a label URL.
+6. **`image.source` and `image.documentation` are the GitHub repo** —
+   `https://github.com/casjaysdevdocker/{name}`.
+7. **One Dockerfile, one file set** — app repos build one image (`latest` + date tag);
+   version variants (`Dockerfile.{ver}`) belong to base repos only.
+8. **Always `FROM casjaysdev/<base>`** — never pull an upstream distro image directly;
+   the base repos exist so every app shares one patched, multi-arch foundation.
+9. **Only `root/`, `tmp/`, and `usr/` may exist at `rootfs/` top level** (PART 1).
+10. **Maintenance runs through the `dockersrc-bootstrap` agent** — do not improvise the
+    update procedure from memory.
+
+---
+
+# PART 1: REPOSITORY MODEL & STRUCTURE
+
+## What an app image repo is
+
+A `casjaysdevdocker/{name}` repo containerizes one application on top of a
+`casjaysdev/*` base. It publishes a single image (`casjaysdevdocker/{name}:latest` plus a
+date tag) — no per-version Dockerfile variants. The application itself is installed in
+`05-custom.sh` and started by one or more init.d service scripts.
+

-## Service Startup Order
+`[generated]` — safe to regenerate; local edits will be lost.
+`[generated*]` — regenerated from the template, EXCEPT files carrying repo-specific
+content (`05-custom.sh` with a real body, extra bin scripts, a hand-crafted README) —
+those follow the hand-crafted rules in PARTs 5 and 6.
+`[hand-crafted]` — never overwritten by the template system.
 
-Services start in this order to ensure dependencies are available:
+App repos may additionally carry project files (`IDEA.md`, `CLAUDE.md`, `TODO.AI.md`)
+per the global project conventions — they are repo-owned and never touched by tooling.
 
-1. **01-clamav.sh** - Antivirus daemon (other services depend on scanning)
-2. **02-tika.sh** - Search indexing service
-3. **03-radicale.sh** - Calendar/Contacts (CalDAV/CardDAV)
-4. **04-collabora.sh** - Document collaboration
-5. **05-opencloud.sh** - Main OpenCloud server
-6. **06-nginx.sh** - Reverse proxy (last, needs all backends)
+## rootfs top-level policy
 
-## Environment Variables
+The only valid directories at the `rootfs/` root are `root/`, `tmp/`, and `usr/`.
+Anything else is a leftover from old patterns. Migration map:
 
-### Domain Configuration
+| Old rootfs path | Correct rootfs path |
+|-----------------|---------------------|
+| `rootfs/etc/{path}` | `rootfs/tmp/etc/{path}` |

+| `rootfs/data/{path}` | `rootfs/tmp/var/{path}` |
+| `rootfs/var/{path}` | `rootfs/tmp/var/{path}` |
+| `rootfs/opt/{path}` | `rootfs/tmp/opt/{path}` |

-| Variable | Default | Description |
-|----------|---------|-------------|

-| `OC_DOMAIN` | `${DOMAIN:-$HOSTNAME}` | OpenCloud domain (for URL generation) |
-| `COLLABORA_SERVER_NAME` | `collabora.${DOMAIN:-$HOSTNAME}` | Collabora server identifier for WOPI |
+`rootfs/usr/local/share/template-files/` is retired — the `DEFAULT_TEMPLATE_DIR`,
+`DEFAULT_FILE_DIR`, `DEFAULT_DATA_DIR`, and `DEFAULT_CONF_DIR` variables were removed
+from the template system; the entrypoint installs staged files from `rootfs/tmp/etc/`
+at container start instead.

-## Usage
-
-### Basic Run
+A repo is an **app** repo when no `Dockerfile.*` variant files exist:
 
 ```bash
-docker run -d \
-  --name opencloud \
-  -p 80:80 \
-  -v opencloud-config:/config \
-  -v opencloud-data:/data \
-  casjaysdevdocker/opencloud:latest start
+if find . -maxdepth 1 -name 'Dockerfile.*' -type f | grep -q -- .; then
+  REPO_TYPE="base"
+else
+  REPO_TYPE="app"
+fi
 ```
 
-### With Custom Admin Password
+---
+
+# PART 2: TEMPLATE SYSTEM REFERENCE
+
+Templates ship with `gen-dockerfile`, installed at
+`/usr/local/share/CasjaysDev/scripts/templates/dockerfiles/`
+(`$CASJAYSDEVDIR/templates/dockerfiles/` in a dev checkout). To inspect what the current
+templates produce, generate a fresh reference tree in a temp dir:
 
 ```bash
-docker run -d \
-  --name opencloud \
-  -p 80:80 \
-  -e ADMIN_PASSWORD=mysecurepassword \
-  -v opencloud-config:/config \
-  -v opencloud-data:/data \
-  casjaysdevdocker/opencloud:latest start
+gen-dockerfile /tmp/gen-dockerfile/{org}/{repo} {distro}
 ```
 
-### Docker Compose
+See `gen-dockerfile --help` for supported distros/types. Keep this PART in sync whenever
+the templates change.
+
+## Template inventory
+
+The template name selects the base OS family; for an app repo the resulting pull URL is
+always the matching `casjaysdev/*` image:
+
+| Template | Final stage | Init / PID 1 | App pulls FROM |
+|----------|-------------|--------------|----------------|
+| `alpine.template` | `scratch.template` | tini | `casjaysdev/alpine` |
+| `debian.template` | `scratch.template` | tini | `casjaysdev/debian` |
+| `ubuntu.template` | `scratch.template` | tini | `casjaysdev/ubuntu` |
+| `rhel.template` | `scratch.template` | tini | `casjaysdev/almalinux` |
+| `archlinux.template` | `scratch.template` | tini | `casjaysdev/archlinux` (multi-arch manifest) |
+| `web.template` | `systemd.template` | `/sbin/init` | `casjaysdev/web` |
+| `xorg.template` | `systemd.template` | `/sbin/init` | `casjaysdev/xorg` |
+
+Default template for app repos is `alpine` unless the application needs systemd, a GUI
+stack, or a distro-specific package.
+
+## Final-stage templates
+
+`scratch.template` — all non-GUI templates.
+- `ENTRYPOINT [ "tini", "-p", "SIGTERM","--", "/usr/local/bin/entrypoint.sh" ]`
+- `STOPSIGNAL SIGRTMIN+3`
+
+`systemd.template` — `web` and `xorg` (systemd is PID 1; tini is redundant).
+- `ENTRYPOINT [ "/sbin/init" ]`
+- `STOPSIGNAL SIGRTMIN+3`
+- No `tini_provider` stage, no `COPY --from=tini_provider` line.
+
+Both are identical apart from `ENTRYPOINT`. OCI labels, `ENV HOSTNAME`, and
+`VOLUME`/`EXPOSE`/`HEALTHCHECK` are the same in both.
+
+## OCI label standard
+
+Both final-stage templates emit these labels (no others):
+
+```
+LABEL maintainer="${GEN_DOCKERFILE_MAINTAINER}"
+LABEL org.opencontainers.image.vendor="${GEN_DOCKERFILE_VENDOR:-CasjaysDev}"
+LABEL org.opencontainers.image.authors="${GEN_DOCKERFILE_AUTHOR:-CasjaysDev}"
+LABEL org.opencontainers.image.licenses="${LICENSE}"
+LABEL org.opencontainers.image.title="${IMAGE_NAME}"
+LABEL org.opencontainers.image.description="Containerized version of ${IMAGE_NAME}"
+LABEL org.opencontainers.image.created="${BUILD_DATE}"
+LABEL org.opencontainers.image.version="${BUILD_VERSION}"
+LABEL org.opencontainers.image.revision="${GIT_COMMIT}"
+LABEL org.opencontainers.image.url="${GEN_DOCKERFILE_HUB_REPO}"
+LABEL org.opencontainers.image.source="${GEN_DOCKERFILE_GIT_REPO}"
+LABEL org.opencontainers.image.documentation="${GEN_DOCKERFILE_GIT_REPO}"
+LABEL org.opencontainers.image.vcs-type="Git"
+LABEL com.github.containers.toolbox="false"
+```
+
+Shell-expanded values (no `\`) are evaluated at template-render time by `gen-dockerfile`.
+Dollar-escaped values (`\${...}`) become literal Docker `ARG`/`ENV` references in the
+generated `Dockerfile`.
+
+Resolved values for a `casjaysdevdocker` repo pushing to Docker Hub:
+
+| Label | Value |
+|-------|-------|
+| `url` | `https://hub.docker.com/r/casjaysdevdocker/{name}` — browsable Hub page; `gen-dockerfile` derives it from the registry host (`docker.io` → `hub.docker.com/r/`) |
+| `source` | `https://github.com/casjaysdevdocker/{name}` |
+| `documentation` | `https://github.com/casjaysdevdocker/{name}` |
+
+Older app repos may still carry `url="https://docker.io/casjaysdevdocker/{name}"` — that
+is the stale form; regeneration corrects it. Removed labels (never re-add):
+- `org.opencontainers.image.base.name` — belongs on the base image, not this image
+- `org.opencontainers.image.schema-version` — non-spec; redundant with `version`
+- Any duplicate `authors` or `source` entries
+
+## HOSTNAME convention
+
+All templates set `ENV HOSTNAME="casjaysdevdocker-${IMAGE_NAME}"` in every stage that
+declares it. The prefix is always `casjaysdevdocker-`, never `casjaysdev-`.
+
+## `GEN_DOCKERFILE_APP_DIR` and pull URL logic
+
+`GEN_DOCKERFILE_APP_DIR` is auto-detected by `gen-dockerfile` from the parent directory
+of `$PWD` (the org the checkout lives in):
+
+```bash
+GEN_DOCKERFILE_APP_DIR="${GEN_DOCKERFILE_APP_DIR:-$(basename -- "$(dirname -- "$PWD")")}"
+```
+
+It selects the `GEN_DOCKER_SPECIFY_IMAGE_SOURCE_*` defaults:
+
+- `casjaysdevdocker/*` repos → `FROM casjaysdev/<distro>:latest` (pre-built, multi-arch)
+- `dockersrc/*` and all other orgs → `FROM <distro>:latest` (upstream official images)
+
+App repos must resolve to the `casjaysdev/*` branch — a checkout outside
+`~/Projects/*/casjaysdevdocker/` needs `GEN_DOCKERFILE_APP_DIR="casjaysdevdocker"`
+exported before calling `gen-dockerfile`, or the regenerated Dockerfile silently reverts
+to upstream distro pulls (rule 8 violation).
+
+## Arch Linux apps
+
+`casjaysdev/archlinux` is a multi-arch manifest (`linux/amd64` + `linux/arm64`), so app
+repos use a single `FROM ${PULL_URL}:${DISTRO_VERSION} AS build` — the three-stage
+`base-${TARGETARCH}` FROM block belongs to the base repo only.
+
+## `web.template` / `xorg.template` notes
+
+`web` apps inherit the systemd + noVNC stack (`SERVICE_PORT="5800"`,
+`EXPOSE_PORTS="5800 5900"` defaults); `xorg` apps inherit the systemd + Xorg stack. App
+packages go in `ENV_PACKAGES` / `02-packages.sh`, never by editing the template's stack
+list.
+
+## `debian.template` / `ubuntu.template` — RUN continuation
+
+The first `RUN` block must have `; \` after the `echo` line so
+`export DEBIAN_FRONTEND=noninteractive` executes before `apt-get`:
+
+```dockerfile
+RUN set -e; \
+  echo "Updating the system"; \
+  export DEBIAN_FRONTEND=noninteractive; \
+  apt-get update && apt-get upgrade -yy && apt-get dist-upgrade -yy
+```
+
+Without the `; \` the export is a no-op and `apt-get` may prompt interactively.
+
+## Template resolution order
+
+1. `$GEN_DOCKERFILE_CONFIG_DIR/templates/<name>.template` (user override)
+2. `/usr/local/share/CasjaysDev/scripts/templates/dockerfiles/<name>.template`
+   (installed; `$CASJAYSDEVDIR/templates/dockerfiles/` in a dev checkout)
+
+`template_options.source` is sourced after `__set_variables`, allowing template-specific
+variable overrides.
+

+
+# PART 3: TOOLING — gen-dockerfile & gen-script
+
+## `gen-dockerfile`
+
+```
+Usage: gen-dockerfile [options] [dir] [template] [repo-name] [git-repo-url]
+```
+
+| Flag | Meaning |
+|------|---------|
+| `--update` | Rewrite `.env.scripts` (add/drop vars against the current template) and update ARG/LABEL lines in the `Dockerfile`. Touches no other file. |
+| `--nogit` | Do not init or commit a git repo — required inside an existing repo. |
+| `--dir PATH` | Operate on / write output to PATH instead of `$PWD`. |
+| `--template NAME` | Template to use (`alpine`, `debian`, `ubuntu`, `rhel`, `archlinux`, `scratch`, `web`, `xorg`). Defaults to `alpine`. |
+| `--repo NAME` | Registry repo name (image basename). Defaults to the directory name. |
+| `--org NAME` | Registry owner / GitHub org (`--user` is an alias). Prefix `git:` or `reg:` to scope to one system; bare value sets both. For app repos both are `casjaysdevdocker`. |
+| `--registry URL` | Registry provider URL (e.g. `https://docker.io`). |
+| `--tag VERSION` | Image version tag (default `latest`). |
+| `--add-tags TAGS` | Comma-separated additional tags (`USE_DATE` = auto date tag). |
+| `--distro-name IMG` | Base image pull URL (overrides `ENV_PULL_URL`). |
+| `--distro-version T` | Base image tag (overrides `ENV_DISTRO_TAG`). |
+| `--startup FILE` | Generate an init.d service script at `rootfs/usr/local/etc/docker/init.d/FILE` via `gen-script other/start-service`. |
+| `--dockerfile` | Regenerate the Dockerfile only. |
+| `--force` | Overwrite existing files without prompting. |
+
+Resolution order when a value is not given by a flag: flags → git remote → project dirs →
+defaults.
+
+Special subcommand — `gen-dockerfile actions` writes `.gitea/workflows/build.yml` from
+the existing `Dockerfile` (PART 7). App repos have no versioned `build.{ver}.yml` files.
+
+## `gen-script`
+
+```
+Usage: gen-script [options] [template] [filename]
+```
+
+| Flag / env var | Meaning |
+|----------------|---------|
+| `--dir PATH` | Write the generated file to `PATH/filename`. |
+| `-n` / `--name VALUE` | Service name substituted into the template — fills `REPLACE_SERVICE_NAME` in `other/start-service`, pre-populating `SERVICE_NAME=` without a sed step. |
+| `GEN_SCRIPT_OVERWRITE="Y"` | Overwrite the output without prompting (default `"A"` = ask). Required when the target exists, even with `GEN_SCRIPT_EDITFILE="N"`. |
+| `GEN_SCRIPT_EDITFILE="N"` | Suppress the interactive editor after generation. `-e`/`--no` sets BOTH this AND `GEN_SCRIPT_OVERWRITE="Y"`; the env var alone does not. |
+| `other/start-service` | Template path — positional arg 1, slash-joined words, matching the `@@Template` header. |
+| `filename` | Output basename — positional arg 2, combined with `--dir`. |
+
+Other flags: `-k`/`--keep` (never overwrite), `--replace` (new header replaces old),
+`-d`/`--desc` (header description), `-p`/`--prev` (copy header metadata from a file).
+
+---
+
+# PART 4: `.env.scripts` REFERENCE
+
+Generated at the repo root; sourced by `gen-dockerfile` and by CI at build time. App
+repos carry exactly one. It is a pure `KEY="value"` file — no logic.
+
+## Variables
+
+| Variable | Purpose |
+|----------|---------|
+| `ENV_DOCKERFILE` | Dockerfile to build (`Dockerfile`) |
+| `ENV_REGISTRY_REPO` | Image name in the registry (`{name}`) |
+| `ENV_REGISTRY_ORG` | Registry namespace — `casjaysdevdocker` for app repos |
+| `ENV_REGISTRY_URL` | Registry base URL (`https://docker.io`) — pull/push host, never a label URL |
+| `ENV_REGISTRY_PUSH` | Full push path `org/repo` (`casjaysdevdocker/{name}`) |
+| `ENV_ADD_IMAGE_PUSH` | Extra push destinations |
+| `ENV_GIT_REPO_URL` | Full Git repo URL — `https://github.com/casjaysdevdocker/{name}`; feeds the `source`/`documentation` labels, so a wrong value here regresses labels on regeneration |
+| `ENV_USE_TEMPLATE` | Template name (`alpine`, `debian`, …) — the authoritative record of which base family the app builds on |
+| `ENV_PULL_URL` | Base image to pull FROM (`casjaysdev/<base>`) |
+| `ENV_DISTRO_TAG` | Tag for the pull image (`latest`) |
+| `ENV_IMAGE_TAG` | Default image tag (`latest`) |
+| `ENV_ADD_TAGS` | Additional comma-separated tags; `USE_DATE` auto-generates a date tag |
+| `ENV_PACKAGES` | Space-separated package list |
+| `ENV_VENDOR` / `ENV_AUTHOR` / `ENV_MAINTAINER` | Label metadata |
+| `SERVICE_PORT` | Primary exposed port — apps normally set this |
+| `EXPOSE_PORTS` | Additional exposed ports |
+| `PHP_VERSION` / `NODE_VERSION` / `NODE_MANAGER` | Runtime versions (`system` default) |
+| `WWW_ROOT_DIR` | Web root (`/usr/local/share/httpd/default`) |
+| `DOCKER_ENTYPOINT_PORTS_WEB` / `DOCKER_ENTYPOINT_PORTS_SRV` | Ports passed to the entrypoint |
+| `DOCKER_ENTYPOINT_HEALTH_APPS` / `DOCKER_ENTYPOINT_HEALTH_ENDPOINTS` | Healthcheck targets |
+
+## Legacy variable auto-migration
+
+`gen-dockerfile` calls `__migrate_env_script` on every run, renaming old variables:
+
+| Old name | Current name |
+|----------|-------------|
+| `ENV_IMAGE_NAME` | `ENV_REGISTRY_REPO` |
+| `ENV_IMAGE_PUSH` | `ENV_REGISTRY_PUSH` |
+| `ENV_HUB_BASE` | `ENV_REGISTRY_URL` |
+| `ENV_ORG_NAME` | `ENV_REGISTRY_ORG` |
+
+Never use the old names in new files. Retired variables that must not reappear anywhere:
+`DEFAULT_TEMPLATE_DIR`, `DEFAULT_FILE_DIR`, `DEFAULT_DATA_DIR`, `DEFAULT_CONF_DIR`.

+
+# PART 5: RUNTIME SYSTEM — SETUP SCRIPTS, ENTRYPOINT, INIT.D
+
+## Build-time setup scripts (`rootfs/root/docker/setup/`)
+
+Run in order inside the build stage:
+
+| Script | Role |
+|--------|------|
+| `00-init.sh` | Initialize base directory structure and environment |
+| `01-system.sh` | Repos, locales, timezone, system settings |
+| `02-packages.sh` | App-specific packages, package managers, language runtimes |
+| `03-files.sh` | Install staged files (`rootfs/tmp/etc/*` → `/etc/*`), permissions, symlinks |
+| `04-users.sh` | Create service users/groups |
+| `05-custom.sh` | Application install logic — the heart of an app repo |
+| `06-post.sh` | Post-install configuration |
+| `07-cleanup.sh` | Remove build deps, caches, temp files |
+
+**`05-custom.sh` ownership:** the upstream template ships an empty stub. An app repo's
+`05-custom.sh` carries the application install (download/build, users, default config) —
+that content exists only in the repo's git history, never in the template. On
+regeneration, keep the existing body and pull forward only boilerplate (version-stamp
+header, `set` line, shellcheck-disable line). The same rule applies to any other `0*.sh`
+found to contain real logic beyond the stub.
+
+## Entrypoint flow
+
+```
+tini → /usr/local/bin/entrypoint.sh
+├─ Load /usr/local/etc/docker/functions/entrypoint.sh
+├─ Source env: /root/env.sh, /usr/local/etc/docker/env/*.sh, /config/env/*.sh
+├─ Seed /config and /data on first run
+├─ __start_init_scripts — source every init.d/*.sh in sort order
+├─ Handle `healthcheck` command
+└─ Execute main application
+```
+
+`rootfs/usr/local/bin/` generated set: `entrypoint.sh`, `pkmgr`, `symlink`, `copy`,
+`healthcheck`. `pkmgr` wraps the native package manager (`apk`, `apt-get`, `dnf`,
+`pacman`) behind `pkmgr update|install|remove|clean`.
+
+## App-specific bin scripts
+
+Extra scripts in `rootfs/usr/local/bin/` that `gen-dockerfile` does not generate are
+repo-owned. Their `@@Template` header governs maintenance:
+
+- `@@Template : shell/sh` — boilerplate synced from `$TEMPLATE_DIR/scripts/shell/sh`;
+  `#!/usr/bin/env sh`, `set -e` only (`pipefail` is a bashism — must NOT appear)
+- `@@Template : shell/bash` — synced from `shell/bash`; `set -eo pipefail` required
+- No `@@Template` header — hand-written; never modified by tooling
+
+## init.d scripts — critical rules
+
+**Each service gets its own numbered init.d script. Never merge or remove services.**
+`__start_init_scripts` sources every `*.sh` in sort order — multi-process apps have one
+script per daemon (e.g. gitea: `05-dockerd.sh`, `08-gitea.sh`, `zz-act_runner.sh`).
+
+init.d scripts are **regenerated, never patched in place** — old copies may call functions
+removed from the current `functions/entrypoint.sh`. Generate fresh via
+`gen-script other/start-service` (or `gen-dockerfile --startup`), then restore the
+app-specific values. They are `#!/usr/bin/env bash` with `set -eo pipefail`.
+
+Required variables in every init.d script:
+
+```bash
+SERVICE_NAME="myapp"
+EXEC_CMD_BIN='myapp'
+EXEC_CMD_ARGS=''
+EXEC_PRE_SCRIPT=''
+SERVICE_USES_PID=''
+IS_WEB_SERVER="no"
+IS_DATABASE_SERVICE="no"
+USES_DATABASE_SERVICE="no"
+DATABASE_SERVICE_TYPE="sqlite"
+RUNAS_USER="root"
+```
+
+Directory variables:
+
+```bash
+DATA_DIR="/data/$SERVICE_NAME"
+CONF_DIR="/config/$SERVICE_NAME"
+ETC_DIR="/etc/$SERVICE_NAME"
+LOG_DIR="/data/logs/$SERVICE_NAME"
+TMP_DIR="/tmp/$SERVICE_NAME"
+RUN_DIR="/run/$SERVICE_NAME"
+ROOT_FILE_PREFIX="/config/secure/auth/root"
+USER_FILE_PREFIX="/config/secure/auth/user"
+```
+
+## Hook functions
+
+The `start-service` template generates all outer hooks fully implemented — customise via
+the matching `*_local()` stub, which each outer hook calls automatically if defined:
+
+| Outer hook (do not redefine) | Customise via |
+|------------------------------|---------------|
+| `__run_precopy` | `__run_precopy_local` |
+| `__execute_prerun` | `__execute_prerun_local` |
+| `__run_pre_execute_checks` | `__run_pre_execute_checks_local` |
+| `__update_conf_files` | `__update_conf_files_local` |
+| `__pre_execute` | `__pre_execute_local` |
+| `__post_execute` | `__post_execute_local` |
+| `__pre_message` | `__pre_message_local` |
+| `__update_ssl_conf` | `__update_ssl_conf_local` |
+| `__create_service_env` | — |
+| `__run_start_script` | — |
+| `__run_secure_function` | — |
+
+## PID sentinel guard
+
+Every init.d script must guard on exactly this sentinel — leading dot, no underscores in
+the filename portion; any other form silently skips the guard:
+
+```bash
+if [ ! -f "/run/.start_init_scripts.pid" ]; then
+  echo "__start_init_scripts function hasn't been Initialized" >&2
+  SERVICE_IS_RUNNING="no"
+  __script_exit 1
+fi
+```
+
+## Volumes
+
+- `/config` — persistent configuration
+- `/data` — persistent application data
+
+---
+
+# PART 6: README.md STANDARD LAYOUT
+
+App image layout (`casjaysdevdocker/{name}` → `casjaysdevdocker/{name}`). Substitute
+`{name}` and `{port}` (the value of `SERVICE_PORT`); omit all `-p`/`ports:` sections only
+in the rare case `SERVICE_PORT` is empty.
+
+**Hand-crafted README exception:** a repo whose README deliberately diverges from this
+layout (full env-var tables, app-specific quick-start flags — e.g. gitea) owns its README.
+Update its facts (image name, org, ports, URLs), never rewrite its structure back to the
+generated layout.

-- `/` → OpenCloud (port 9200)
-- `/cool/` → Collabora WebSocket

-## Technical Notes
+## Authors
 
-### Base Image
+🤖 casjay: [Github](https://github.com/casjay) 🤖
+⛵ casjaysdevdocker: [Github](https://github.com/casjaysdevdocker) [Docker](https://hub.docker.com/u/casjaysdevdocker) ⛵
+````
 
-Uses Debian-based image (not Alpine) because Collabora CODE requires glibc.
+---
 
-### SSL/TLS
+# PART 7: CI/CD WORKFLOWS
 
-SSL is disabled by default (`PROXY_TLS=false`) as the container is designed to run behind a reverse proxy that handles TLS termination.
+## Generated workflow (`gen-dockerfile actions`)
 
-### ClamAV Virus Definitions
+`gen-dockerfile actions` writes `.gitea/workflows/build.yml` from the current
+`Dockerfile`. App repos get the single `build.yml` only — no versioned variants. All
+actions are SHA-pinned — never tag-pinned.
 
-Virus definitions are downloaded during image build to reduce container startup time. Updates can be performed by restarting the container or running `freshclam` manually.
+- **Triggers:** `push` to `main`, monthly schedule, `workflow_dispatch`
+- **Registry strategy:** always logs in to the Gitea registry via the auto-provided
+  `GITEA_TOKEN`; conditionally logs in to Docker Hub when `vars.DOCKER_USERNAME` is set
+  (`vars.DOCKER_USERNAME` + `secrets.DOCKER_PASSWORD`; `vars.DOCKER_REGISTRY` overrides
+  the registry, `vars.DOCKER_ORG` the namespace)
+- **Platforms:** `linux/amd64,linux/arm64`
+- **build-args:** only `BUILD_DATE`, `GIT_COMMIT`, `BUILD_VERSION`
+- **Tags pushed:** date tag (`yymm`) + `latest` to both registries
+- **Annotations:** mirror the OCI label standard (PART 2), with `url`/`source`/
+  `documentation` set to the workflow's repository URL
 
-### Collabora User
+## Legacy workflow (`docker.yaml`)
 
-Collabora CODE must run as the `cool` user (not root) for security reasons.
+A hand-crafted `.gitea/workflows/docker.yaml` may exist in older repos — reference copy in
+the org-level `.github` repo. **Never overwrite it, and never use it as a template for new
+work** — it uses tag-pinned actions and retired secret names. All new/updated workflows
+come from `gen-dockerfile actions`.
 
-### Admin Password
+---
 
-If `ADMIN_PASSWORD` is not set, a random 16-character password is generated and saved to `/config/secure/auth/root/opencloud_admin_pass`.
+# PART 8: VERIFICATION & COMMIT
 
-## Troubleshooting
+## Syntax gates
 
-### Check Service Status
+Every touched script must pass before commit:
 
 ```bash
-docker logs opencloud-test 2>&1 | grep -E "completed|Error|Starting"
+for f in rootfs/usr/local/bin/*; do
+  [ -f "$f" ] || continue
+  case "$(head -1 "$f")" in
+    *bash*) bash -n "$f" || exit 1 ;;
+    *sh*)   sh -n "$f"   || exit 1 ;;
+  esac
+done
+
+bash -n rootfs/usr/local/etc/docker/functions/entrypoint.sh
+
+for f in rootfs/root/docker/setup/0*.sh rootfs/usr/local/etc/docker/init.d/*.sh; do
+  [ -f "$f" ] || continue
+  bash -n "$f" || exit 1
+done
 ```
 
-### Access Container Shell
+## Dead-reference gates
+
+After any regeneration:
+
+1. No script references an env var removed from `.env.scripts` (diff-driven check).
+2. No script calls a function absent from both the current
+   `functions/entrypoint.sh` and the script itself.
+3. No `__copy_templates` calls remain (retired with `DEFAULT_TEMPLATE_DIR`).
+4. `Dockerfile` still pulls `FROM casjaysdev/*` (rule 8) — an upstream distro pull means
+   `GEN_DOCKERFILE_APP_DIR` resolved wrong during regeneration.
+
+## Commit
 
 ```bash
-docker exec -it opencloud /bin/bash
+git status --porcelain
+git diff --stat
 ```
 
-### Check Running Processes
+Write `.git/COMMIT_MESS` from the actual diff — subject ≤64 chars, body as
+`- path: change` bullets covering every changed file. Then:
 
 ```bash
-docker exec opencloud ps aux
+gitcommit --dir "$(git rev-parse --show-toplevel)" all
 ```
 
-### View Service Logs
-
-```bash
-# OpenCloud
-docker exec opencloud cat /data/logs/opencloud/opencloud.log
-
-# Nginx
-docker exec opencloud cat /data/logs/nginx/access.log
-
-# Collabora

-## Files Structure
-
-### Setup Scripts (`/root/docker/setup/`)
-
-- `02-packages.sh` - Base package installation info (actual packages in ENV_PACKAGES)
-- `03-files.sh` - Downloads OpenCloud binary, Tika JAR, ClamAV definitions
-- `04-users.sh` - Creates opencloud user and group
-
-### Init Scripts (`/usr/local/etc/docker/init.d/`)
-
-- `01-clamav.sh` - ClamAV antivirus daemon
-- `02-tika.sh` - Apache Tika search service
-- `03-radicale.sh` - Radicale CalDAV/CardDAV
-- `04-collabora.sh` - Collabora CODE
-- `05-opencloud.sh` - OpenCloud server
-- `06-nginx.sh` - Nginx reverse proxy
-
-### Configuration Templates
-
-- `/usr/local/share/template-files/config/` - Default configurations
-- `/etc/radicale/config` - Radicale default config
-
-## Package List
-
-Packages installed via `ENV_PACKAGES`:
-
-- Core: ca-certificates, curl, wget, bash, tini, gnupg, apt-transport-https, tzdata, procps, netcat-openbsd, nginx
-- Java: default-jre-headless (for Tika)
-- Python: python3, python3-pip, python3-venv (for Radicale)
-- Antivirus: clamav, clamav-daemon, clamav-freshclam
-
-Additional packages installed in `03-files.sh`:

-
-## Version Information
-
-- OpenCloud: Latest from GitHub releases (auto-detected)
-- Apache Tika: 2.9.1
-- Radicale: Latest from pip
-- Collabora CODE: Latest from official repository
-
-## Known Limitations
-
-1. Single container deployment - not suitable for high-availability setups
-2. ClamAV definitions are from build time - consider periodic updates
-3. No built-in SSL - requires external reverse proxy for HTTPS
-4. Memory intensive due to Java (Tika) and Collabora
-5. Collabora CODE may require additional configuration for production use - check `/usr/bin/discovery.xml`
-
-## Current Service Status
-
-- **ClamAV**: Working
-- **Apache Tika**: Working
-- **Radicale**: Working
-- **Collabora CODE**: Requires additional configuration (may fail on first run)
-- **OpenCloud**: Dependent on Collabora for document editing features
-- **Nginx**: Working (serves as reverse proxy)

+# OpenCloud All-in-One Docker Container
+
+## Overview
+
+This is a comprehensive all-in-one Docker container for OpenCloud, a Go-based file sync and share platform (successor to ownCloud). The container includes all integrated services required for a full-featured deployment.
+
+## Included Services
+
+| Service | Port | Purpose |
+|---------|------|---------|
+| ClamAV | Socket | Antivirus scanning for uploaded files |
+| Apache Tika | 9998 | Full-text search and document extraction |
+| Radicale | 5232 | CalDAV/CardDAV for Calendar and Contacts |
+| Collabora CODE | 9980 | Document collaboration (LibreOffice Online) |
+| OpenCloud | 9200 | Core file sync/share platform |
+| Nginx | 80 | Reverse proxy (external-facing) |
+
+## Architecture
+
+```
+                    +------------------+
+                    |      Nginx       |
+                    |     (Port 80)    |
+                    +--------+---------+
+                             |
+        +--------------------+--------------------+
+        |          |         |         |          |
+   +----v----+ +---v---+ +---v---+ +---v---+ +---v---+
+   |OpenCloud| |Collabora| |Radicale| | Tika | |ClamAV |
+   | (9200)  | | (9980)  | | (5232) | |(9998)| |(sock) |
+   +---------+ +---------+ +--------+ +------+ +-------+
+```
+
+## Service Startup Order
+
+Services start in this order to ensure dependencies are available:
+
+1. **01-clamav.sh** - Antivirus daemon (other services depend on scanning)
+2. **02-tika.sh** - Search indexing service
+3. **03-radicale.sh** - Calendar/Contacts (CalDAV/CardDAV)
+4. **04-collabora.sh** - Document collaboration
+5. **05-opencloud.sh** - Main OpenCloud server
+6. **06-nginx.sh** - Reverse proxy (last, needs all backends)

+Collabora CODE must run as the `cool` user (not root) for security reasons.
+
+### Admin Password
+
+If `ADMIN_PASSWORD` is not set, a random 16-character password is generated and saved to `/config/secure/auth/root/opencloud_admin_pass`.
+
+## Troubleshooting
+
+### Check Service Status
+
+```bash
+docker logs opencloud-test 2>&1 | grep -E "completed|Error|Starting"
+```
+
+### Access Container Shell
+
+```bash
+docker exec -it opencloud /bin/bash
+```
+
+### Check Running Processes
+
+```bash
+docker exec opencloud ps aux
+```
+
+### View Service Logs
+
+```bash
+# OpenCloud
+docker exec opencloud cat /data/logs/opencloud/opencloud.log
+
+# Nginx
+docker exec opencloud cat /data/logs/nginx/access.log
+
+# Collabora
+docker exec opencloud cat /data/logs/collabora/collabora.log
+```
+
+## Files Structure
+
+### Setup Scripts (`/root/docker/setup/`)
+
+- `02-packages.sh` - Base package installation info (actual packages in ENV_PACKAGES)
+- `03-files.sh` - Downloads OpenCloud binary, Tika JAR, ClamAV definitions
+- `04-users.sh` - Creates opencloud user and group
+
+### Init Scripts (`/usr/local/etc/docker/init.d/`)
+
+- `01-clamav.sh` - ClamAV antivirus daemon
+- `02-tika.sh` - Apache Tika search service
+- `03-radicale.sh` - Radicale CalDAV/CardDAV
+- `04-collabora.sh` - Collabora CODE
+- `05-opencloud.sh` - OpenCloud server
+- `06-nginx.sh` - Nginx reverse proxy
+
+### Configuration Templates
+
+- `/usr/local/share/template-files/config/` - Default configurations
+- `/etc/radicale/config` - Radicale default config
+
+## Package List
+
+Packages installed via `ENV_PACKAGES`:
+
+- Core: ca-certificates, curl, wget, bash, tini, gnupg, apt-transport-https, tzdata, procps, netcat-openbsd, nginx
+- Java: default-jre-headless (for Tika)
+- Python: python3, python3-pip, python3-venv (for Radicale)
+- Antivirus: clamav, clamav-daemon, clamav-freshclam
+
+Additional packages installed in `03-files.sh`:
+- Collabora: coolwsd, code-brand (from Collabora repository)
+- Radicale: installed via pip
+
+## Version Information
+
+- OpenCloud: Latest from GitHub releases (auto-detected)
+- Apache Tika: 2.9.1
+- Radicale: Latest from pip
+- Collabora CODE: Latest from official repository
+
+## Known Limitations
+
+1. Single container deployment - not suitable for high-availability setups
+2. ClamAV definitions are from build time - consider periodic updates
+3. No built-in SSL - requires external reverse proxy for HTTPS
+4. Memory intensive due to Java (Tika) and Collabora
+5. Collabora CODE may require additional configuration for production use - check `/usr/bin/discovery.xml`
+
+## Current Service Status
+
+- **ClamAV**: Working
+- **Apache Tika**: Working
+- **Radicale**: Working
+- **Collabora CODE**: Requires additional configuration (may fail on first run)
+- **OpenCloud**: Dependent on Collabora for document editing features
+- **Nginx**: Working (serves as reverse proxy)
