+# Changes Log
+
+## 2026-03-23
+
+### Added
+- Created `.idea/start prompt.md` as a persistent project working prompt for future sessions.
+- Added `.idea/changes.md` as the preferred in-project location for the detailed session change log.
+- Added release notes support in the active Bahmcloud Store runtime path: backend provider fetching, a dedicated API endpoint, and panel display for the currently selected version when provider release notes are available.
+- Bumped the Home Assistant panel asset cache-buster from `v=109` to `v=110` so the updated frontend loads reliably after deployment.
+- Bumped the integration version from `0.7.2` to `0.7.3`.
+- Added the `0.7.3` release entry to `CHANGELOG.md` with the new release-notes and project-workflow changes.
+
+### Documented
+- Captured the verified project identity from the repository and README files: Bahmcloud Store is a Home Assistant custom integration intended to behave like a provider-neutral store for custom integrations, similar to HACS but broader than GitHub-only workflows.
+- Recorded the actual active architecture from source analysis, including the config-entry-only setup, the fixed Bahmcloud store index, delayed startup refresh, periodic refresh, repo merge flow, cache usage, install/update/uninstall pipeline, backup/restore pipeline, update entities, and Repairs-based restart handling.
+- Recorded the current provider reality from code: GitHub, GitLab, and Gitea-compatible repositories are the concrete supported paths today, while truly generic "all git providers" support is still an intention and must be validated case by case.
+- Recorded the public API endpoints exposed by `views.py` so future work preserves the current backend contract unless a deliberate breaking change is approved.
+- Recorded storage facts from `storage.py`, including the `bcs_store` Home Assistant storage key and the persisted sections for custom repositories, installed repositories, settings, HACS cache, and repo enrichment cache.
+- Recorded frontend facts from the active panel registration in `__init__.py` and the active frontend implementation in `panel/panel.js`, including the cache-busting panel asset version query.
+- Updated the persistent start prompt to point future work to `.idea/changes.md` as the canonical detailed work log.
+- Release notes are intentionally tied to provider release objects, so tags or branches without release bodies now return a clear "not available" state instead of misleading fallback text.
+
+### Important findings from code analysis
+- Identified `custom_components/bahmcloud_store/panel/panel.js` as the active Home Assistant panel script currently loaded by the integration.
+- Identified `custom_components/bahmcloud_store/panel/app.js`, `custom_components/bahmcloud_store/panel/index.html`, and `custom_components/bahmcloud_store/panel/styles.css` as likely legacy or secondary assets that should not be treated as authoritative without verification.
+- Identified `custom_components/bahmcloud_store/store.py` as an older implementation with a different data model and API shape than the active `BCSCore` runtime.
+- Identified `custom_components/bahmcloud_store/custom_repo_view.py` as duplicate or legacy API code because the active custom-repo handling already exists in `views.py`.
+- Noted that the README set is directionally useful but not fully authoritative where it conflicts with current code behavior.
+- Noted that some repository files contain encoding or mojibake artifacts, so future edits should preserve valid UTF-8 and avoid spreading broken text.
+
+### Project rules written into the start prompt
+- Never push, commit, tag, or create a release without explicit user approval.
+- Always append a dated and detailed entry to `.idea/changes.md` for every change made.
+- When a release is created, collect all relevant changes since the last release into `CHANGELOG.md`.
+
+### Verification
+- Reviewed repository structure and current git status.
+- Read `README.md`, `README_DEVELOPER.md`, `README_FULL.md`, `bcs.yaml`, and the current `CHANGELOG.md`.
+- Analyzed the active backend files: `__init__.py`, `const.py`, `core.py`, `providers.py`, `metadata.py`, `storage.py`, `views.py`, `config_flow.py`, `update.py`, and `repairs.py`.
+- Checked panel and legacy-related files to distinguish the currently active UI path from older or duplicated files.
+- Verified that the active panel (`panel/panel.js`) now requests release notes from the new backend route and reloads them when the selected install version changes.

+## Bahmcloud Store Start Prompt
+
+You are working in the `Bahmcloud Store` repository.
+
+Project identity:
+- This is a Home Assistant custom integration named `bahmcloud_store`.
+- The product goal is a provider-neutral store for Home Assistant custom integrations, similar in spirit to HACS, but not limited to GitHub.
+- Current real provider implementation is strongest for GitHub, GitLab, and Gitea-compatible providers. Unknown providers currently fall through the Gitea-style code paths, so do not assume every arbitrary Git provider works without verification.
+
+Working rules:
+- Never push, commit, tag, or create a release without explicit user approval.
+- Always document every change in `.idea/changes.md` with the current date and a detailed description of what changed, why it changed, and any verification done.
+- If a new release is created, update `CHANGELOG.md` with all relevant changes since the last released version.
+- Prefer changing the real active code paths, not legacy or duplicate files.
+- When docs and code disagree, trust the current code first, then update docs to match verified behavior.
+- Do not remove user changes or perform destructive git actions unless the user explicitly asks for them.
+
+Repository facts to keep in mind:
+- Main integration path: `custom_components/bahmcloud_store/`
+- Entry point: `__init__.py`
+- Main runtime/service layer: `core.py`
+- HTTP API layer: `views.py`
+- Provider detection and remote version/readme fetching: `providers.py`
+- Repo metadata loading (`bcs.yaml`, `hacs.yaml`, `hacs.json`): `metadata.py`
+- Persistent storage: `storage.py`
+- Update entities: `update.py`
+- Repairs restart flow: `repairs.py`
+- Frontend panel actually loaded by Home Assistant: `panel/panel.js`
+- Panel registration uses `/api/bahmcloud_store_static/panel.js?v=109`; if frontend assets change in a real release, bump the version query to break HA browser cache.
+
+Current architecture summary:
+- Setup is config-entry only. YAML configuration is intentionally unsupported and only logs a warning if present.
+- Only one integration instance is allowed.
+- The official store index URL is fixed in `const.py`:
+  `https://git.bahmcloud.de/bahmcloud/ha_store/raw/branch/main/store.yaml`
+- The store index format currently used by the active code is a YAML mapping with:
+  - `refresh_seconds`
+  - `repos`
+  - each repo entry contains at least `url`, optionally `name` and `category`
+- Refresh flow:
+  - integration initializes storage and caches
+  - after `homeassistant_started`, a delayed refresh runs
+  - periodic refresh also runs on an interval from the store index
+  - refresh merges official index repos, optional HACS repos, and user custom repos
+  - cached enrichment is applied first, installed repos are refreshed eagerly, and the rest are enriched in the background
+- Optional HACS support exists behind the `hacs_enabled` setting and currently loads the official HACS integration list from `data-v2.hacs.xyz`. That path is GitHub-only metadata, not a general provider abstraction.
+- Install/update flow:
+  - picks a ref from selected version, latest version, or default branch
+  - downloads a ZIP from the provider-specific archive endpoint
+  - extracts the repository
+  - finds `custom_components`
+  - installs every integration folder inside `custom_components/*` that contains `manifest.json`
+  - stores the installed ref and manifest version in HA storage
+  - creates backups before overwriting existing domains
+  - marks restart required through Repairs
+- Backup/restore behavior:
+  - backups live under `/config/.bcs_backups/<domain>/<timestamp>/`
+  - restore updates stored installed-version info so the UI and update entities reflect the restored state
+  - retention is currently 5 backups per domain
+- Installed-state reconciliation exists:
+  - if folders are deleted from `/config/custom_components`, stale installed entries are removed from storage
+  - BCS also tries to self-reconcile as installed when it was deployed externally
+
+Public/API contract to preserve unless intentionally changed:
+- `GET /api/bcs`
+- `POST /api/bcs?action=refresh`
+- `GET /api/bcs/settings`
+- `POST /api/bcs/settings`
+- `GET /api/bcs/readme?repo_id=...`
+- `GET /api/bcs/versions?repo_id=...`
+- `GET /api/bcs/repo?repo_id=...`
+- `POST /api/bcs/install?repo_id=...&version=...`
+- `POST /api/bcs/update?repo_id=...&version=...`
+- `POST /api/bcs/uninstall?repo_id=...`
+- `GET /api/bcs/backups?repo_id=...`
+- `POST /api/bcs/restore?repo_id=...&backup_id=...`
+- `POST /api/bcs/restart`
+- `DELETE /api/bcs/custom_repo?id=...`
+
+Storage model:
+- Home Assistant storage key: `bcs_store`
+- Stored sections:
+  - `custom_repos`
+  - `installed_repos`
+  - `settings`
+  - `hacs_cache`
+  - `repo_cache`
+
+Frontend/UI facts:
+- The active HA panel script is `custom_components/bahmcloud_store/panel/panel.js`.
+- The richer UI is implemented there: source filtering, HACS toggle, repo detail loading, version selection, backups restore modal, restart action, and history handling.
+- `panel/app.js`, `panel/index.html`, and `panel/styles.css` look like older standalone or legacy panel assets. Treat them as secondary unless you confirm they are still used for a real path.
+
+Code-analysis findings that should influence future work:
+- `store.py` represents an older store implementation with a different data model (`packages`, `source_path`, older API routes). It does not appear to be the active runtime path for the current integration flow.
+- `custom_repo_view.py` duplicates logic that already exists in `views.py` and looks legacy/unreferenced.
+- README files describe the project direction correctly at a high level, but some wording overstates provider generality. The actual code is provider-neutral in intent, but concretely implemented around GitHub, GitLab, and Gitea-style endpoints.
+- The end-user and full READMEs contain some stale or inconsistent details compared with the current UI and code. Verify behavior in source before using README text as specification.
+- There are visible encoding/mojibake issues in some documentation and older UI assets. Preserve valid UTF-8 when editing.
+
+Project constraints to respect in future edits:
+- Keep async I/O non-blocking in Home Assistant.
+- Avoid startup-heavy network work before HA is fully started.
+- Preserve repo-cache and HACS-cache behavior unless intentionally redesigning refresh logic.
+- Preserve backup-before-overwrite safety for install/update/restore flows.
+- Preserve update-entity behavior for installed repos.
+- Keep the integration UI-admin-only and config-entry-based.
+
+Recommended workflow for future tasks:
+1. Read `README.md`, `README_DEVELOPER.md`, and relevant source files.
+2. Verify whether the requested change belongs in active code or in legacy files.
+3. Implement the change in the active runtime path.
+4. Update documentation if behavior changed.
+5. Append a detailed dated entry to `.idea/changes.md`.
+6. If and only if a release is being prepared with user approval, fold release-worthy changes into `CHANGELOG.md`.
+
+Current release baseline:
+- `manifest.json` version is `0.7.3`
+- Latest documented release in `CHANGELOG.md` is `0.7.3` dated `2026-03-23`

+## Architecture
+
+Repositories:
+1) Installer Add-on (HAOS/Supervised) ```https://git.bahmcloud.de/bahmcloud/addons```
+2) Core Integration ```https://git.bahmcloud.de/bahmcloud/bahmcloud_store```
+3) Store Index (`store.yaml`) ```https://git.bahmcloud.de/bahmcloud/ha_store```
+
+### Integration Layout
+
+custom_components/bahmcloud_store/
+- __init__.py: setup, panel registration, schedule background after HA started
+- core.py: index merge, enrichment, install/update/uninstall, backups, restore, caching
+- providers.py: GitHub/GitLab/Gitea repo info + latest version helpers
+- metadata.py: read bcs.yaml / hacs.json / hacs.yaml
+- storage.py: persistent storage (installed, custom, repo cache, hacs cache)
+- views.py: HTTP API endpoints
+- update.py: UpdateEntity implementation
+- repairs.py: (optional) Repairs flow for restart

+
+## Runtime Model
+
+- RepoItem (merged)
+- Installed repos (storage)
+- Repo cache (persisted enrichment)
+- HACS meta cache (mapping owner/repo → name/description)
+
+## Background
+
+- Heavy work only after `homeassistant_started`
+- Refresh: if index unchanged → installed-only refresh + schedule enrichment
+- Opening a repo triggers `ensure_repo_details()` and persists to cache
+
+## Providers
+
+- GitHub: API/releases/tags/atom + raw readme
+- GitLab: API releases/tags + raw readme
+- Gitea: API releases/tags + raw readme
+- Custom: API or HTTPS Request to your Git Provider
+
+## Metadata
+
+- Prefer `bcs.yaml`, fallback `hacs.json` / `hacs.yaml`
+- Populate name/description/category/author/maintainer
+
+## HTTP API (excerpt)
+
+Base: /api/bcs
+
+- GET  /api/bcs
+- POST /api/bcs?action=refresh
+- GET  /api/bcs/readme?repo_id=...
+- GET  /api/bcs/versions?repo_id=...
+- POST /api/bcs/install?repo_id=...&version=...

+- GET  /api/bcs/backups?repo_id=...
+- POST /api/bcs/restore?repo_id=...&backup_id=...
+- (optional) POST/DELETE custom_repo
+
+## Update Entities
+
+- Unique id bcs:<repo_id>
+- Compare installed ref vs latest ref
+- Dispatcher signal on refresh/install/update
+
+## Storage
+
+- JSON in HA `.storage`
+- async read/write helpers
+- repo cache applied on startup
+
+## Contributing to **BCS Official**
+
+1) Add pull request to `https://git.bahmcloud.de/bahmcloud/ha_store` (with your integration added to) `store.yaml`)  
+2) Add entry:
+```yaml
+- name: Your Integration Name
+  url: https://your-git-hoster.com/your-org/your-repo
+  category: Category (actually only "Integrations" are supported)
+```
+3) (Recommended) Add `bcs.yaml` to your repo:
+```yaml
+name: Your Integration Name
+description: One-liner for the store (optional, store information are also catched from git repository)
+category: Integrations (actually only supported)
+author: Your Name
+maintainer: Your Handle
+```
+4) Open PR; validation checks: reachable, has `custom_components/<domain>/manifest.json`, sensible metadata
+5) Merge → appears in **BCS Official** after refresh
+
+## Coding Guidelines
+
+- Async I/O, no blocking event loop
+- Respect provider rate limits
+- Clean logging around refresh/install/update/restore
+- Keep UI responsive; throttle updates

+# Bahmcloud Store – Full User Guide
+
+This guide explains **all features** of Bahmcloud Store (BCS) for Home Assistant.
+It is written for users and admins who want a complete, practical reference.
+
+> BCS lets you install & manage custom integrations from **GitHub/GitLab/Gitea** and your own sources, with backups, restore, and version pinning.
+
+---

+## Contents
+- Concepts
+- Sources (BCS / HACS / Custom)
+- UI Overview
+- Finding Integrations
+- Installing
+- Selecting Versions / Downgrading
+- Updating
+- Uninstalling
+- Backups & Restore
+- Custom Repositories
+- HACS Repositories
+- Update Entities in Home Assistant
+- Background Caching & Performance
+- Restart Required
+- Troubleshooting
+- FAQ
+
+---
+
+## Concepts
+
+- **Sources**:
+  - **BCS Official** → entries from index (`store.yaml`) made and added from Bahmcloud
+  - **HACS** → official HACS integrations list (toggleable)
+  - **Custom** → manual entries you add locally
+- **Install location**: `/config/custom_components/<domain>`
+- **Backup**: BCS keeps pre‑update copies in `/config/.bcs_backups/<domain>/<timestamp>/`
+
+---
+
+## Sources (BCS / HACS / Custom)
+
+Each repository card shows a **source badge**:
+- **BCS Official** – from Bahmcloud index
+- **HACS** – from HACS official list (enable with the toggle)
+- **Custom** – added by you
+
+You can **filter by source** with the **Source** dropdown (All / BCS Official / HACS / Custom).
+
+---
+
+## UI Overview
+
+Top bar:
+- **Search** (name/description)
+- **Source** filter (All/BCS Official/HACS/Custom)
+- **Category** filter (actually only Integrations are supported)
+- **State-Filter** filter (All/Installed/Not installed/Update available/Custom repos)
+- **Sort** (name (A-Z)/Updates first/Installed first)
+- **HACS official** toggle (on/off)
+
+Repository card:
+- Name, description, badges (source, installed/update), category
+- Buttons: **Install / Update / Uninstall**
+- **Readme** expandable
+- **Open** to see details (available versions, metadata)
+
+---
+
+## Finding Integrations
+
+1. Use **Search** to filter by keywords.
+2. Combine with **Category** and **Source**.
+3. Sort to surface desired results.
+
+Descriptions and latest versions are filled progressively by a background process; opening a repo loads details on demand.
+
+---
+
+## Installing
+
+1. Open a repository.
+2. Optionally select **Install version** (default: **Latest**).
+3. Click **Install** and wait for confirmation.
+4. Follow the **Restart required** prompt. (or use restart toggle in HomeAssistant Settings)
+
+**What happens internally**
+- BCS downloads the repository ZIP for the selected version (release/tag/branch).
+- It extracts all integrations found under `custom_components/<domain>` and deploys them.
+- It saves the **installed version (ref)** to track updates reliably, even if the repo’s own `manifest.json` is wrong/outdated.
+
+---
+
+## Selecting Versions / Downgrading
+
+- Use the **Install version** dropdown in the detail view.
+- Choose **Latest** or a previous **release/tag**.
+- Installing a chosen ref **pins** the integration to that ref (no surprise updates).
+- You can upgrade again later by selecting **Latest** and clicking **Update**.
+
+---
+
+## Updating
+
+- The **Update** button appears when `latest_version` differs from your **installed version (ref)**.
+- Updates are also available via **Home Assistant → Settings → Updates** (native Update entity).
+- Clicking **Update** runs the same safe pipeline as **Install** (with backup).
+
+**Tip:** Opening a repository detail view forces an immediate check for the latest version for that repo.
+
+---
+
+## Uninstalling
+
+- Click **Uninstall** on the repository.
+- BCS removes the integration folders under `custom_components/<domain>`.
+- The installed state is cleared in the Store.
+- Restart Home Assistant if prompted.
+
+---
+
+## Backups & Restore
+
+Before an update/install over existing files, BCS creates a backup:
+
+```
+/config/.bcs_backups/<domain>/<timestamp>/
+```
+
+**Restore**:
+1. Open the repository in store.
+2. Select **Restore…**.
+3. Pick one of the **last backups** (up to retention limit). (Version details are showed in ())
+4. Confirm – BCS restores files and reconciles installed version to the restored ref.
+5. Restart Home Assistant if prompted.
+
+If the old backup lacks metadata, BCS best‑effort derives the installed version from the backup’s `manifest.json`, or marks the ref as `restored:<timestamp>` so updates remain possible.
+
+---
+
+## Custom Repositories
+
+You can add any public repository (GitHub/GitLab/Gitea/Any other Git Hoster). BCS will attempt to detect:
+- provider & default branch
+- latest version (release/tag/atom)
+- repo metadata (prefer `bcs.yaml`, fallback `hacs.json/hacs.yaml`)
+- readme (common filenames)
+
+**Add an custom repository**(typical flows):
+- From the Store UI
+  1. If you start up Bahmcloud Store, you are on tab "Store"
+  2. Go to tab "Manage" 
+  3. Add Repository URL (Example: ``https://git.bahmcloud.de/bahmcloud/bahmcloud_store``) and (optional) Name you want to show up (will be grabbed from GIT Repository)
+  4. Repository show up in Custom Repositories-list and in "Store" Tab, if available
+
+**Remove an custom repository**(typical flows):
+- From the Store UI
+  1. If you start up Bahmcloud Store, you are on tab "Store"
+  2. Go to tab "Manage" 
+  3. Your repository you want to remove (if its custom) show up in the list
+  4. Press "Remove" Button to delete from Store (Attention: If you Remove installed Repository, you won´t be able to Uninstall from Store, you have to remove by your own (Delete Folder from ```config/custom_components/*```))
+
+Custom repos get the **Custom** badge and can be filtered via **Source**.
+
+---
+
+## HACS Repositories
+
+Enable the **HACS official** toggle to include official HACS integrations.
+
+- BCS downloads the HACS integration list and maps **human‑readable names/descriptions** from HACS metadata.
+- HACS entries are **not** part of your BCS-Official Repositories (avoid duplicate entries).
+
+With many HACS repos, metadata loads in the background; names/descriptions appear progressively and are cached.
+
+---
+
+## Update Entities in Home Assistant
+
+BCS exposes update entities for installed repos:
+- Found under **Settings → Updates**
+- Clicking **Install** triggers BCS update pipeline
+- Shows **installed** and **latest** versions (BCS ref logic)
+
+---
+
+## Background Caching & Performance
+
+- **Fast initial list**: index + local cache only
+- **Background enrichment**: provider info, latest version, metadata, description, readme (best effort)
+- **On‑demand**: opening a repo triggers immediate enrichment; data is **persisted** to cache
+- **Persistent cache**: survives HA restarts; speeds up subsequent runs
+- **Refresh**: immediately rechecks installed repos and key metadata
+
+---
+
+## Restart Required
+
+After install, update, or restore, BCS raises a **Restart required** item in Home Assistant (Repairs). You can restart directly from there.
+
+---
+
+## Troubleshooting
+
+- **New release but no update**: Open the repo detail once; ensure it’s a **release/tag** (commits alone don’t change the ref).
+- **Descriptions/Latest missing**: Wait for background enrichment or open the repo detail (forces enrichment). Cached afterwards.
+(You also can Install new version by selecting in Version tab)
+- **Slow startup**: BCS schedules heavy work after HA started. Keep indexes reasonable.
+
+---
+
+## FAQ
+
+- **Backups path?** `/config/.bcs_backups/<domain>/<timestamp>/`
+- **Install path?** `/config/custom_components/<domain>`
+- **Downgrade?** Yes, pick an older version and install.
+- **Restart needed?** Yes, after install/update/restore.
