+# What's New highlights — GitHub Models release step (reusable)
+#
+# Called by the release-please workflows AFTER a release is created
+# (release-please.yml for `stable`, release-please-beta.yml for `main`). It runs
+# as a job in the SAME workflow run rather than on its own `release: published`
+# trigger, because release-please creates the release with the default
+# GITHUB_TOKEN and GitHub does not start new workflow runs from token-generated
+# events — a standalone `release:` workflow would simply never fire.
+#
+# What it does: condenses the new release's "### Features" into <=8 short
+# bullets via GitHub Models (free tier, `models: read`) and injects a
+# `<!-- whatsnew -->` block at the top of the release notes. The app reads that
+# block (backend utils/whatsNew.parseWhatsNew) and falls back to the raw
+# Features list for releases without it — so this is purely a quality upgrade,
+# never a hard dependency. Failure is isolated by `continue-on-error` + the
+# deterministic fallback below, so it can never break a release.
+#
+# GitHub Models is OPTIONAL. If it is disabled/unavailable for the org the AI
+# step fails soft (continue-on-error) and the deterministic fallback produces
+# the bullets instead — the feature works either way, Models just polishes them.
+#
+# Validated end-to-end on a fork (extract -> openai/gpt-4o-mini -> inject into

+## 🌿 Branch model
+
+PicPeak runs on two long-lived branches:
+
+| Branch | Role | What targets it |
+|---|---|---|
+| **`main`** | Active development. The next release is being assembled here. | Feature PRs. Most bugfix PRs. |
+| **`stable`** | Curated release channel. Production-recommended. | Urgent bugfix backports only — small, surgical PRs that land cleanly without dragging in unrelated changes. |
+
+### Which branch should my PR target?
+
+- **New feature** → target `main`.
+- **Bugfix that ONLY affects active dev** → target `main`.
+- **Bugfix that current stable users need** → open a small PR against `main`, AND a separate small PR against `stable` with the same change. Keep both surgical so each lands cleanly.
+
+**Hard rule on PR scope**: bugfix PRs against `stable` must be small enough to backport without conflict. Omnibus PRs (e.g. five unrelated sub-features) are fine for `main`, but never for `stable` — they make the next `main → stable` merge painful and break the "stable is always shippable" invariant.
+
+If you're not sure which branch to target, default to `main` and a maintainer will retarget during review.
+
 ## 🔄 Release Process
 
-1. Update version numbers in package.json files
-2. Update CHANGELOG.md
-3. Create a new release on GitHub
-4. Docker images are automatically built and published
+Releases are cut independently from `main` (pre-release versions for the active channel) and `stable` (semver releases for the curated channel). `release-please` handles version bumps, changelog generation, and Docker image publication automatically — contributors don't update `package.json` or `CHANGELOG.md` by hand.
+
+Periodic `main → stable` merges promote a batch of `main` work to the stable channel. The maintainer chooses when (typically every ~4 weeks, sooner if a hot bug demands it).
+
+See [RELEASING.md](RELEASING.md) for the full operational doc (promotion criteria, conflict-resolution checklist for the `main → stable` merge, hotfix backport path, versioning rules).

+# Clone the repository
+git clone https://github.com/PicPeak/picpeak.git
 cd picpeak

-# Edit .env — set at least JWT_SECRET and passwords
+
+# Start with Docker Compose

 ```
 
-Open `http://localhost:3000` and log in with the credentials from your `.env`.
+### First run — create your admin account
+
+On first start with no `ADMIN_PASSWORD` set, PicPeak has **no admin account yet** and greets you with an in-browser setup screen — no credentials in `.env`:
+
+1. Open **http://localhost:3000/admin** — you'll be redirected to `/setup`.
+2. Grab the **one-time setup token** from the backend logs (it's also saved to `data/SETUP_TOKEN`):
+   ```bash
+   docker compose logs backend | grep -i "setup token"
+   ```
+3. Paste the token, set your admin **email + password**, and you're in. The token is single-use, and the setup screen closes permanently once an admin exists.
+
+> Prefer the old behaviour? Set `ADMIN_PASSWORD` in `.env` and PicPeak auto-creates the admin on first boot instead (credentials written to `data/ADMIN_CREDENTIALS.txt`).
+
+Note on Docker file permissions
+- The backend container starts as root, chowns bind-mounted host directories (`./storage`, `./data`, `./logs`) to UID 1001 (`nodejs`), then drops privileges via `su-exec` before running the app. No host-side setup needed for fresh installs.
+- If you pin `user:` in a compose override (e.g. to map a specific host UID), the self-chown is skipped and you must pre-chown the host directories to that UID — see [docs.picpeak.app/deployment/docker#permissions](https://docs.picpeak.app/deployment/docker#permissions).
 
 > **Permissions:** Set `PUID` and `PGID` in `.env` to match your host user (`id -u` / `id -g`) so Docker volumes are writable.

+## 🏗️ Tech Stack
+
+- **Backend**: Node.js, Express, SQLite/PostgreSQL
+- **Frontend**: React, Tailwind CSS, Framer Motion
+- **Storage**: Local filesystem (default) or S3-compatible object store (AWS S3, MinIO, R2, B2, Wasabi, Spaces) — see [Storage Backends](#storage-backends)
+- **Email**: SMTP with customizable templates
+- **Analytics**: Privacy-focused with Umami integration
+
+## 💾 Storage Backends
+
+PicPeak supports two storage backends for photos, thumbnails, hero images, watermarks, and archive zips. Both are configured via environment variables; no code change is required to switch.
+
+| Capability | `STORAGE_BACKEND=local` (default) | `STORAGE_BACKEND=s3` |
+|---|---|---|
+| Photo / thumbnail / hero storage | Local filesystem under `STORAGE_PATH` | Bucket on any S3-compatible service |
+| Admin UI upload | ✅ | ✅ |
+| Filesystem auto-import (chokidar watcher) | ✅ | ❌ — disabled (use the upload API) |
+| Watermarks, fingerprinting, fragmentation | ✅ | ✅ (materialized to a tmp file just-in-time) |
+| Bulk download zips (cached + on-the-fly) | ✅ | ✅ |
+| Backups | ✅ | ✅ |
+| External media reference mode (`EXTERNAL_MEDIA_ROOT`) | ✅ (always local) | ✅ (still local — not migrated) |
+
+### Switching to an S3-compatible backend
+
+1. Provision a bucket and credentials. The minimum IAM policy is documented in `.env.example`.
+2. Set `STORAGE_BACKEND=s3` plus `STORAGE_S3_BUCKET`, `STORAGE_S3_REGION`, `STORAGE_S3_ACCESS_KEY`, `STORAGE_S3_SECRET_KEY`. For non-AWS providers (MinIO, R2, B2, …) also set `STORAGE_S3_ENDPOINT`.
+3. If you have existing local content, copy it first: `node backend/scripts/migrate-storage.js --dry-run` then `node backend/scripts/migrate-storage.js`. The script is idempotent and writes a failures CSV.
+4. Restart the backend. The startup check pings the bucket and refuses to boot on misconfig.
+
+Note: presigned-URL serving (zero-bandwidth direct downloads from S3) is intentionally **not** in v1 — every request still streams through the backend so watermarks, devtools-detection, and access logging keep working.
+
+## 🔔 Webhooks
+
+PicPeak POSTs event/photo lifecycle notifications to URLs you configure under **Settings → Webhooks**. Each delivery is signed `HMAC-SHA256` with a per-webhook secret in the `X-PicPeak-Signature` header so receivers can verify the request really came from your PicPeak instance.
+
+### Event types
+
+| Event | Fires when |
+|---|---|
+| `event.created` | Gallery created (admin or API) |
+| `event.published` | Draft becomes live (`is_draft: true → false`) — also fires when an event is created with `is_draft=false` |
+| `event.archived` | Bulk-archive, manual archive, or auto-archive on expiry |
+| `event.expired` | Expiration checker marks the gallery inactive (fires before `event.archived` in the cascade) |
+| `photo.uploaded` | Admin upload, API upload, guest upload, or auto-import |
+| `photo.deleted` | Single delete, bulk delete (NOT fired per-photo when an event is archived — receivers infer from `event.archived` to avoid flooding) |
+
+### Payload shape
+
+```json
+{
+  "id": "delivery-uuid",
+  "type": "event.published",
+  "created_at": "2026-04-28T05:25:00.000Z",
+  "data": {
+    "event": { "id": 123, "slug": "wedding-smith", "share_url": "https://..." }
+  }
+}
+```
+
+Also sent on every request:
+- `X-PicPeak-Signature` — `HMAC-SHA256(secret, raw_body)` as hex
+- `X-PicPeak-Event` — the event type (handy for routing without parsing the body)
+- `X-PicPeak-Delivery` — UUID for idempotency on the receiver side
+- `User-Agent: PicPeak-Webhooks/1.0`
+
+### Verifying signatures
+
+**Node.js**
+```js
+const crypto = require('crypto');
+function verify(secret, rawBody, signature) {
+  const expected = crypto.createHmac('sha256', secret).update(rawBody).digest('hex');
+  const a = Buffer.from(expected, 'hex');
+  const b = Buffer.from(signature, 'hex');
+  if (a.length !== b.length) return false;
+  return crypto.timingSafeEqual(a, b);
+}
+```
+
+**Python**
+```python
+import hmac, hashlib
+def verify(secret: str, raw_body: bytes, signature: str) -> bool:
+    expected = hmac.new(secret.encode(), raw_body, hashlib.sha256).hexdigest()
+    return hmac.compare_digest(expected, signature)
+```
+
+**curl + openssl** (one-liner for a quick replay)
+```sh
+SIG=$(printf '%s' "$BODY" | openssl dgst -sha256 -hmac "$SECRET" | awk '{print $2}')
+[ "$SIG" = "$RECEIVED_SIG" ] && echo OK || echo MISMATCH
+```
+
+### Retries + observability
+
+- `2xx` → success, recorded with latency
+- Non-`2xx` or network error → exponential backoff: `1m → 5m → 30m → 2h → 12h`, max 5 attempts
+- After max attempts: status `failed`, surfaces in **Settings → Webhooks → Deliveries** with a "Replay" button
+- Up to 5 deliveries in flight at once; one slow consumer can't block others (configurable via `WEBHOOK_DELIVERY_CONCURRENCY`)
+- Response body truncated to 1KB before storage so chatty receivers don't bloat the audit log
+
+The deliveries page (`/admin/webhooks/:id/deliveries`) shows every attempt with timestamp, status, HTTP code, latency, payload sent, signature, and response. Click "Send test event" to fire a synthetic delivery for any event type.
+
+### SSRF protection
+
+Webhook URLs are validated against the same private-IP blocklist used elsewhere in the app — loopback, private RFC1918 ranges, link-local, `.local`/`.internal` hostnames, cloud metadata endpoints. The check runs both at create time and per-delivery (DNS-rebinding mitigation).
+
+For local development with a receiver on the same machine or docker network, set `WEBHOOK_ALLOW_PRIVATE_URLS=true`. Production deployments must leave this OFF.
+
+## 💻 System Requirements
+
+### Minimum Requirements
+- **CPU**: 2 CPU cores
+- **RAM**: **4 GB minimum** for a normal photo-upload workload — sharp/libvips
+  decodes the full uncompressed frame before resize, and the default two
+  worker loops at sharp-concurrency 2 can push peak RSS past 1.5 GB on a
+  batch of 20-MP+ photos. On a 2 GB VPS that's enough to OOM-kill the
+  backend mid-batch (surfaces as 503s on thumbnails — see [Low-memory
+  hosts](#low-memory-hosts) below for the recipe to run on 2 GB).
+- **Storage**: 20GB minimum (plus photo storage needs)
+- **OS**: Linux (Ubuntu 20.04+), macOS, or Windows with WSL2
+- **Node.js**: v18.0.0 or higher
+- **Database**: SQLite (included) or PostgreSQL 12+
+
+### Docker Requirements (Recommended)
+- **Docker**: v20.10.0+
+- **Docker Compose**: v2.0.0+
+
+### Low-memory hosts
+
+Running on 2 GB RAM (e.g. an entry-level VPS) is workable but requires
+tuning the upload-processor concurrency down. The backend auto-detects
+total RAM at startup via `os.totalmem()` — on a host that reports < 3 GB,
+it defaults `UPLOAD_PROCESSOR_CONCURRENCY` to **1** instead of 2 and logs
+a one-shot warning. You can pin the value explicitly in `.env`:
+
+```env
+# Single worker loop — slower batch processing, lower peak RSS
+UPLOAD_PROCESSOR_CONCURRENCY=1
+```
+
+The trade-off is throughput: a single worker processes one photo at a
+time, so a 100-photo batch takes ~2× as long but won't OOM. **Health-check
+note**: if the backend dies under memory pressure, the gallery serves
+`503 Service Unavailable` on thumbnails until Docker's
+`restart: unless-stopped` brings the container back. Persistent 503s
+during/after an upload batch on a low-memory host are almost always this.
+
+### Video Support Requirements
+When enabling video uploads, consider these additional resources:
+
+| Resource | Recommendation | Notes |
+|----------|----------------|-------|
+| **RAM** | 4GB+ recommended | FFmpeg processing requires more memory |
+| **Storage** | Plan for 10-100x more | Videos are significantly larger than images |
+| **CPU** | Additional cores help | Video thumbnail extraction is CPU-intensive |
+| **Bandwidth** | Higher throughput | Video streaming requires more bandwidth |
+
+**Technical Notes:**
+- FFmpeg is bundled via npm (`@ffmpeg-installer/ffmpeg`) - no system installation required
+- Maximum upload size: **10GB per video file**
+- Chunked upload support for files >100MB (resumable uploads)
+- Supported formats: MP4, WebM, MOV, AVI
+- Video thumbnails are automatically generated from the first few seconds
+
+**For Nginx/Reverse Proxy:**
+If using Nginx, increase the client max body size:
+```nginx
+client_max_body_size 10G;
+proxy_read_timeout 3600;
+proxy_send_timeout 3600;
+```

+## 🙏 Acknowledgments
+
+PicPeak is inspired by the best features of commercial platforms while remaining completely open source. Special thanks to all contributors who make this project possible.
+
+### 👥 Contributors
+
+A huge thank you to the people whose code, reports, and feedback have shaped PicPeak:
+
+- [**@the-luap**](https://github.com/the-luap) — creator and lead maintainer. Started the project and built PicPeak's foundation and the entire gallery experience (events, galleries, uploads, sharing, download protection, templates), plus backup & restore, analytics, system health, branding/theming, and WhatsApp notifications — and the architecture every later feature builds on.
+- [**@Luca-Timo**](https://github.com/Luca-Timo) — native Apple Silicon multi-arch images, external-URL toggle for legal CMS pages, the lazy-loaded folder tree picker, the admin-email picker on event creation, the data-driven self-hosted webfont system, the gallery header/banner decoupling, several typed-API refactors, and the CRM + accounting suite (quotes/contracts/invoices, hours logging, calendar, tax report, inbound supplier-invoice capture, expenses, and the Treuhänder/Banana export). Consistently raises the bar with thoughtful PRs.
+- [**@Rekoo-PS**](https://github.com/Rekoo-PS) — sharp-eyed bug reporter and product feedback. Filed the issues that drove the login-loop fix, the gallery-loading skeleton work, the redirection cleanup, the mobile-lightbox overhaul, the admin-events search-counter fix, the photo-count column, and the bulk-delete workflow. Also a [BuyMeACoffee](https://buymeacoffee.com/theluap) supporter — the kind of feedback loop that keeps the project useful for real deployments.
+
+If you've contributed and aren't listed here, please open a PR — this list is meant to grow.
+
+### 🤖 AI-Assisted Development
+
+This project was generated with the assistance of AI technology, but has been:
+- ✅ **Fully tested end-to-end** by human developers
+- 🔒 **Security audited** with comprehensive security checks
+- 👨‍💻 **Human-reviewed** for code quality and best practices
+- 🧪 **Production-tested** in real-world scenarios
+
+We believe in transparent development practices and the responsible use of AI as a tool to accelerate development while maintaining high standards of quality and security.
+
+## ⚠️ CRM & Accounting disclaimers — examples only, verify locally
+
+The CRM & accounting modules (contracts, invoices, QR-bills, the tax
+report and the accountant exports) ship seeded content and computed
+figures that are intended as a **starting point only**:
+
+- **Contract blocks** (image rights, NDA, model release, cancellation,
+  jurisdiction, …) are written by the maintainer, **not by a lawyer**.
+  Every operator must have their lawyer review and adapt them before
+  sending any contract to a customer.
+- **QR-bills and SEPA EPC payloads** are rendered from the data you
+  typed. Picpeak is open source — please scan a test invoice with your
+  bank's app to check the QR actually works. We are not responsible for
+  any mistakes that come from sending an invoice with bad data on it.
+- **Tax, VAT & accounting figures** (the tax report, VAT-payable, the
+  per-rate breakdown, the Treuhänder / Banana export, etc.) are computed
+  from the data you enter and the defaults you configure. They are
+  **guidance only and jurisdiction-specific** — tax rules, VAT rates,
+  deduction schemes (e.g. the Liechtenstein 20 % Gewinnungskosten flat
+  rate) and filing duties differ by country and change over time. **Every
+  operator must check their own tax / VAT regulations and verify the
+  numbers with their accountant / Treuhänder / tax authority before
+  relying on any figure or export.** Picpeak makes no warranty that the
+  output is correct for your jurisdiction or situation.
+
+Read [`docs/crm-disclaimers.md`](docs/crm-disclaimers.md) before
+enabling the Contracts, Invoices or Accounting features.

+# Release Process
+
+This document describes how PicPeak releases are cut. It's the maintainer's reference, not user documentation — for the user-facing channel choice (stable vs pre-release) see the [Release Channels section in README.md](README.md#-release-channels).
+
+## TL;DR
+
+- **`main` branch** receives all merged work (active development). Every push triggers a `release-please` PR that proposes the next `vX.Y.Z-beta.N` pre-release. Merging that PR tags the pre-release and publishes Docker images under the `:main` rolling tag + the version-specific tag.
+- **`stable` branch** holds the curated stable channel. Stable releases are cut from a known-good `main` point via a `release/X.Y.Z-merge-from-main` branch and a manual PR to `stable`. Merging that PR triggers `release-please` to propose the stable release.
+- Target cadence: **a stable release every 4–6 weeks**, or sooner if `main` has been quiet and ready for promotion.
+
+> **Branch model background** — `main` (active dev) was previously called `beta`, and `stable` (curated channel) was previously called `main`. The rename happened with #669 to match the convention every other open-source project uses. The mechanics below all reference the post-rename names.
+
+## Cadence target
+
+4–6 weeks between stable releases is the working target. Reasoning:
+
+- Long enough that each stable carries meaningful changes worth the upgrade burden.
+- Short enough that pre-release users aren't carrying the "real" project alone for months — the stable channel should actually be usable as the recommended channel for new installs.
+- Aligns with how release-please surfaces pre-releases (multiple pre-release points usually accumulate inside a 4–6 week window, which gives natural promotion candidates).
+
+This is a target, not a hard rule. Cut sooner if `main` has been quiet and stable longer than usual. Cut later if `main` is in flux for security or migration reasons.
+
+## Promotion criteria
+
+A `main` tip is eligible for promotion to `stable` when **all** of the following hold:
+
+1. **CI green on the candidate `main` tip.** Specifically: `schema-drift` (`upgrade-from-bootstrap`), `fresh-install`, `Tests` (backend Jest + frontend Vitest), the four `Build and Push Docker Images` arch matrices, and `GitGuardian Security Checks`.
+2. **No open `bug`-labelled issues against the candidate for at least 7 days.** Issues fixed-but-not-yet-closed count as fixed; verify their PR is in the candidate `main` tip before closing them out.
+3. **An upgrade walk has been done on real production-shaped data** — apply the candidate's migration chain to a snapshot of the previous stable's DB and verify no manual intervention is required. CI proves fresh-install works; the upgrade walk is what proves the upgrade path works.
+4. **Operator-time smoke** on the candidate: log in, create event, upload photos, share gallery, open as a customer, log out. Catches binary-incompatibility regressions and UI-level breaks that unit tests don't see.
+
+If any of the four fail, the promotion waits. File any blockers as `bug`-labelled issues and let them bake on `main` before re-evaluating.
+
+## How a stable release is cut
+
+The actual mechanics, in order:
+
+1. **Pick the `main` tip.** Confirm it satisfies the four promotion criteria above. Note the exact SHA — that's what you're promoting.
+
+2. **Create the release branch from the `main` tip.**
+   ```bash
+   git push origin <main-tip-sha>:refs/heads/release/X.Y.Z-merge-from-main
+   ```
+   Naming convention: `release/X.Y.Z-merge-from-main`, where `X.Y.Z` is the stable version you intend to land. release-please will write the actual `X.Y.Z` on merge — the branch name is just a human label.
+
+3. **Open a PR to `stable`.** Title: `chore(release): promote main → stable as vX.Y.Z`. Body should summarise the major themes since the previous stable, the migration count, and any operator notes (e.g. "this release adds 22 migrations; existing installs should snapshot before upgrading"). See PR #568 as a worked example (predates the rename; the mechanics are unchanged).
+
+4. **Resolve conflicts.** `stable` almost always has commits `main` doesn't (security backports, release-please's stable-channel release commits, README rewrites). For each conflicting file, decide deliberately:
+   - **`backend/package.json` / `package-lock.json` + `frontend/package.json` / `package-lock.json`** — usually take `main`'s version (superset), but verify any security-pinned deps (`axios`, `nodemailer`, `i18next-http-backend`, `multer`, `tar`) on `main` are `>=` the pinned versions on `stable`. If `stable` has a newer pinned version (e.g. an emergency CVE backport `main` hasn't picked up), take `stable`'s pin.
+   - **`README.md`** — keep `stable`'s version if it has had a recent rewrite that `main` didn't pick up; otherwise take `main`'s.
+   - **`CHANGELOG.md`** — keep `stable`'s; release-please regenerates entries on its next stable cut from the commits going forward.
+   - **`.release-please-manifest.json`** — keep `stable`'s; release-please owns this file.
+   - Any other auto-merged file — spot-check that the auto-merge produced something sensible, especially for security-sensitive files (`backend/src/middleware/`, `backend/src/utils/tokenUtils.js`).
+
+5. **Wait for CI on the PR.** All ten checks (the original eight plus `merge-backend` and `merge-frontend`) must be green. If anything fails, fix on the release branch (NOT on `main` — `main` has already moved on).
+
+6. **Merge.** Standard merge commit, not squash — the PR's history (the individual feature commits) carries forward into `stable`'s log.
+
+7. **release-please picks it up.** Within minutes, release-please will open a new `chore(stable): release X.Y.Z` PR proposing the stable release. Review the auto-generated CHANGELOG.md entries for accuracy, edit if needed, and merge. That merge creates the `vX.Y.Z` git tag, publishes Docker images on the `:stable` and `:latest` tags, and creates the GitHub Release page.
+
+8. **Close the loop.** Bulk-close any `bug` issues that were fixed-but-not-closed and now appear in the released changelog. Reference the merge commit so reporters know which version contains the fix.
+
+## Hotfix path (backport to current stable)
+
+If a critical bug or security issue affects the current stable and `main` has moved too far for a full promotion to be appropriate, backport just the fix:
+
+1. Create a `security/cve-backport-X.Y.Z` or `fix/critical-X.Y.Z` branch off `stable`.
+2. Cherry-pick or hand-write the minimal fix.
+3. Open a PR to `stable` with the smallest possible diff.
+4. After merge, release-please will propose a patch-level stable release (e.g. `v3.55.1`).
+5. **Forward-port the fix to `main`** if it isn't already there. Otherwise the next full promotion will reintroduce the bug.
+
+PR #412 ("backport 18 dependency CVE patches from beta") is a worked example of this path (predates the rename; the mechanics are unchanged).
+
+## Versioning
+
+PicPeak follows [Semantic Versioning](https://semver.org/) with one project-specific convention:
+
+- **MAJOR** bumps are reserved for breaking schema changes that require operator action on upgrade (e.g. a migration that's not safe to auto-apply, an env-var rename that can't be auto-detected).
+- **MINOR** bumps for new features, additive schema changes, and any change to the public HTTP API surface.
+- **PATCH** bumps for bug fixes and operator-invisible internal changes.
+- **Pre-release suffix** (`-beta.N`) for every `main`-channel cut; the `N` counter resets on each new MINOR or MAJOR target. The suffix kept the historical `-beta` literal even after the branch rename — operators were already pinning to `v3.x.y-beta.N` and changing the literal would have broken those pins.
+
+release-please derives all of this from conventional commit prefixes (`feat:`, `fix:`, `BREAKING CHANGE:`, etc.) automatically.
+
+## Things that don't go through this process
+
+- **Documentation-only changes** can land on either `stable` or `main` directly (no release cut needed); release-please will pick them up on the next regular release.
+- **Test-only changes** — same.
+- **CI / workflow changes** — same, but be aware they take effect on the branch they land on, so a CI fix targeting `main` won't fix a broken stable-channel workflow until the next promotion.
+
+## When this doc is wrong
+
+If you find yourself working around something here, update the doc before doing the workaround. The point of a written process is that future-you doesn't have to remember the workaround.

+## 🔑 First Login — Create Your Admin
+
+If you installed with `picpeak-setup.sh` and gave an `--admin-password`, your admin account already exists — log in at `/admin` with that email and password.
+
+If you started PicPeak **without** setting `ADMIN_PASSWORD` (e.g. a plain `docker compose up`), there's **no admin yet** and you create it in the browser:
+
+1. Open `http://your-server:3000/admin` — you'll land on a setup screen.
+2. Get the **one-time setup token** from the backend logs (also saved to `data/SETUP_TOKEN`):
+   ```bash
+   docker compose logs backend | grep -i "setup token"
+   ```
+3. Paste it, set your admin email + password. The token is single-use and the screen closes once an admin exists.

+/**
+ * Integration test for GET /api/admin/system-health/backup-coverage.
+ *
+ * Pins the Stage C diagnostic that tells admins what the next
+ * "Run Backup Now" will include, skip, or silently miss.
+ *
+ * Test surface:
+ *   1. Empty / fresh install → default seed (7 paths), inline mode,
+ *      no DB dump on file yet, no drift
+ *   2. Toggle `include_in_default=false` → coverage flips to
+ *      'skipped-by-toggle'
+ *   3. Feature_flag gating reflects the actual app_settings value
+ *      (events/archived ⇄ backup_include_archived)
+ *   4. Drift detection: a top-level subdir on disk with no
+ *      `backup_paths` row is flagged in `unconfiguredOnDisk`
+ *   5. Allow-list: `backups/` and `tmp/` are never flagged as drift
+ *   6. Scheduled-only mode + recent dump → `database.ok = true`
+ *   7. Scheduled-only mode + stale (>26h) dump → `database.ok = false`
+ *      and `lastDumpStale = true`
+ *
+ * Same auth/permission pass-through strategy as
+ * adminBackupIntegrity.test.js — we exercise the route's logic,
+ * not the auth middleware.

+ * list of storage subdirectories (events/active, events/archived,
+ * thumbnails, previews, heroes, uploads) and silently omitted the
+ * entire `business-docs/` tree. That meant every CRM PDF + signature
+ * drawing — quotes, contracts (system-rendered + wet uploads),
+ * invoices, Storno, imported historical invoices, and the customer
+ * signature PNG/JPG drawn on the public signing page — fell outside
+ * the in-app scheduled backup, leaving every `*_path` column on
+ * `quotes` / `contracts` / `invoices` as a broken FK after restore.
+ *
+ * The fix is a single `scanDirectory(business-docs, ...)` call. This
+ * suite pins the contract so a future refactor of the walker cannot
+ * silently drop business-docs again.

+// `getFilesToBackupInternal` before returning, OR to skip walking a
+// path if a longer one has already covered it.

+ *   - findByShortSlug returns soft-deleted rows (caller decides 410 vs 404)

+ *   - Non-empty trigger file → uses the path inside
+ *   - DB not empty → refuses (no restore call)
+ *   - DB not empty + FORCE env → proceeds
+ *   - Successful restore → deletes trigger file
+ *   - Failed restore → leaves trigger file in place
+ *
+ * These are the surfaces an admin will hit when actually using the

+/**
+ * Pins the fix for the PR #596 review blocker.
+ *
+ * **The bug**
+ *
+ *   `preservedMeta` was declared with `let` INSIDE the PostgreSQL
+ *   `else` branch of `performDatabaseRestore`, then read AFTER the
+ *   `else` block closed at the shared replay site (~L1030). On every
+ *   real PG restore:
+ *
+ *     ReferenceError: preservedMeta is not defined
+ *
+ *   would fire — psql had already completed the data restore, but
+ *   the operator-meta replay never ran, the trigger file was left
+ *   in place by `_installFromBackupBoot.js` because the restore
+ *   "failed", and `combined.log` got a loud FAILED line even though
+ *   the data was back. Caught on PR #596 review by the maintainer.
+ *
+ * **Why CI missed it**
+ *
+ *   The integration tests around `performFullRestore` only exercise
+ *   the SQLite branch via `this.dbType === 'sqlite'`. The PG branch
+ *   (~L827-984) requires a real PG connection + real `psql` binary,
+ *   neither of which are in the test environment. So the scope leak
+ *   sat untested until the maintainer ran a real DR cycle.
+ *
+ * **What this test does**
+ *
+ *   Reads the source of `restoreService.js` and asserts the scope
+ *   contract: the `preservedMeta` declaration sits ABOVE the
+ *   SQLite/PG branch split, so the replay block at the bottom of the
+ *   try{} can read it on either branch.
+ *
+ *   Source-inspection is uglier than a runtime test but it has two
+ *   advantages here: (a) it doesn't require a real PG cluster + psql
+ *   binary in CI, (b) it pins the EXACT contract — "the declaration
+ *   must be visible to the replay block" — which is the property
+ *   that broke, more directly than a runtime test would.
+ *
+ *   The follow-up "real-PG integration test in CI" (separate task)
+ *   would replace this with an end-to-end exercise, at which point
+ *   this can be deleted.

+ *   - Valid token + super_admin role → 2xx / 404 (resource-based)

+ * Unit tests for the WhatsApp template-parameter selection (#647 follow-up).
+ *
+ * Pins:
+ *  - parseTemplateParams sanitizes unknown / non-string / duplicate keys,
+ *    and falls back to the default 5-slot shape on empty / malformed input.
+ *  - buildComponents emits ONLY the listed slots, in the listed order, so
+ *    a 2-parameter template (event_name + gallery_link) sends exactly 2
+ *    positional values — the reporter's exact case from issue #647.
+ *  - The legacy 5-slot default still works unchanged for installs that
+ *    haven't reconfigured.

+/**
+ * Migration 107 — CRM consolidated schema + seeds.
+ *
+ * ---------------------------------------------------------------------------
+ *
+ * Single migration that brings up the entire CRM feature area:
+ *
+ *   - Quotes / Invoices / Contracts data layer (tables, FKs, indexes)
+ *   - Payment-term templates (legacy + split: net-days + timing)
+ *   - Installment plans, deal_uuid lineage across quotes / contracts /
+ *     invoices, monthly billing accumulator
+ *   - Customer hour-logging tables + customer-side feature flags
+ *   - Admin calendar columns on events, pre-event reminder columns
+ *   - Document sequence helper (gap-free atomic numbering)
+ *   - Email templates seeded for all CRM lifecycle events (en + de)
+ *   - RBAC permissions for the new resources (split customers.* too)
+ *   - Feature flags (quotes / bills / contracts / hoursLogging / taxReport /
+ *     calendar / calendarBooking / reminderEmails / crmDevelopment / messaging)
+ *
+ * Replaces the in-flight chain of 42 separate migrations (102..143 on
+ * the `feat/crm` branch). Each table is created in its FINAL form via
+ * a single createTable() — no ALTER chains. Seeds are grouped by target
+ * table at the bottom.
+ *
+ * ---------------------------------------------------------------------------
+ *
+ * Sections (in order):
+ *
+ *   1. Issuer block — business_profile (singleton) + business_bank_accounts
+ *   2. Payment-term templates — legacy + split (net-days + timing)
+ *   3. Quotes — table, line items, line-item presets, action tokens
+ *   4. Invoices — table, line items, payment log
+ *   5. Contracts — table, blocks, block inclusions, action tokens,
+ *      signatures, payments-tokens
+ *   6. Event ↔ document glue — event_payment_plans
+ *   7. Customer hour logging — customer_hour_entries
+ *   8. Document sequences — atomic gap-free numbering helper
+ *   9. ALTER existing upstream tables — events / customer_accounts /
+ *      monthly_billings / app_settings / admin_users
+ *  10. Seeds — payment-term templates (system rows)
+ *  11. Seeds — split payment templates (net-days + timing)
+ *  12. Seeds — email templates (8 from 102 + per-event-type reminders)
+ *  13. Seeds — RBAC permissions (4 new + split customers.*)
+ *  14. Seeds — feature flags + app_settings (CRM defaults, ToS,
+ *      payment defaults, reminder defaults, locked roadmap force-off)
+ *
+ * ---------------------------------------------------------------------------
+ *
+ * Idempotency: every step is guarded by hasTable / hasColumn / row-
+ * existence check. Safe to re-run; safe on a partial-state DB.
+ *
+ * Money is INTEGER minor units (cents/Rappen) + ISO 4217 currency code.
+ * Never DECIMAL/FLOAT — avoids floating-point drift on totals.
+ *
+ * Cross-dialect: tested on SQLite + PostgreSQL. JSON columns use
+ * `t.jsonb` where available (`t.json` falls back).
+ *
+ * Translations: en + de hand-translated. fr/nl/pt/ru are intentionally
+ * absent on email templates; the renderer falls through to en until
+ * the admin overrides them via Templates UI. Flag for native review
+ * in the PR description.

+/**
+ * Migration 109 — config-driven backup walker.
+ *
+ * (Originally numbered 108 on bugfix/crm-backup. Renumbered to 109
+ * before merge because upstream/beta independently shipped
+ * 108_seed_sl_email_template_translations.js. The createTable is
+ * idempotent via `hasTable` guard and the seed uses
+ * `onConflict('path').ignore()`, so beta installs that ran the
+ * 108-named version of this file get a harmless no-op when 109
+ * runs against the already-seeded table.)
+ *
+ * Stage B of the three-stage backup-hardening plan. The file-backup
+ * walker (`getFilesToBackupInternal` in backupService.js) historically
+ * hard-coded its list of subdirectories: events/active, events/archived,
+ * thumbnails, previews, heroes, uploads, business-docs.
+ *
+ * That list is a footgun every time a new feature lands that drops
+ * artefacts under STORAGE_PATH/<something>/ — the maintainer has to
+ * remember to edit the walker, and there's no schema-level record of
+ * what *should* be backed up. The CRM rollout missed `business-docs`
+ * for ~6 months (#XXX) for exactly this reason.
+ *
+ * This migration introduces a `backup_paths` table that the walker
+ * reads at runtime. New features add a row; the walker picks them up
+ * automatically. The `feature_flag` column gates scans behind an
+ * existing app_settings boolean (e.g. `backup_include_archived`),
+ * mirroring how the previous `includeArchived` parameter worked.
+ *
+ * Columns:
+ *   - path                : relative to STORAGE_PATH, unique
+ *   - include_in_default  : on/off without deleting the row (so
+ *                           audit trail of "we used to back this up"
+ *                           is preserved)
+ *   - feature_flag        : nullable; when set, walker checks the
+ *                           same-named app_settings boolean before
+ *                           scanning. Matches the existing pattern
+ *                           used by `backup_include_archived`.
+ *   - display_order       : controls admin-UI listing order
+ *   - description         : human-readable purpose, shown in admin UI
+ *
+ * Defense-in-depth: the walker also keeps a hard-coded LEGACY_DEFAULTS
+ * fallback so that if this table is somehow empty (failed migration on
+ * an existing install, manual truncation), backups still cover the
+ * historical set instead of silently shipping nothing. The boot-time
+ * self-heal in `_backupPathsBoot.js` re-seeds missing default rows on
+ * every startup so newly-added defaults reach already-deployed
+ * installs without a follow-up migration.
+ *
+ * Idempotent: skips the createTable if it already exists, and the
+ * seed uses `onConflict('path').ignore()` so re-runs don't duplicate.

+ * as positional parameters to the configured Meta template (and in what
+ * order). Reporter @Rekoo-PS hit the gap that motivated this: their

+ * matching `gallery_ready` — so Meta rejected with a parameter-count
+ * mismatch even after the language fix landed (migration 137).
+ *
+ * Schema: TEXT column, empty/null means "fall back to the legacy 5-slot
+ * shape" so installs that haven't reconfigured continue to work without
+ * intervention. The processor's `buildComponents` reads this column,
+ * parses the array, and emits only the listed slots in the listed order.
+ *
+ * Known slot keys (any other keys are ignored): `customer_name`,
+ * `event_name`, `gallery_link`, `password_line`, `expiry_date`.
+ *

+ * PR #646 (138 — slideshow_share, 139 — slideshow_styling). Additive +

+ * reset-admin-mfa.js — disable two-factor auth for a locked-out admin (#738).
+ *
+ * Break-glass recovery for when an admin loses their authenticator AND their
+ * recovery codes. Clears the MFA state so the admin can log in with just their
+ * password and re-enroll from Settings.
+ *
+ * Usage (inside the running backend container):
+ *   docker compose exec backend node scripts/reset-admin-mfa.js --email admin@example.com
+ *   docker compose exec backend node scripts/reset-admin-mfa.js --all --yes
+ *
+ * Flags:
+ *   --email <addr>   target a single admin by email (or --username <name>)
+ *   --all            reset MFA for EVERY admin (full lockout / break-glass)
+ *   --yes            non-interactive (skip the confirmation prompt)

+/**
+ * Admin calendar aggregate endpoint.
+ *
+ * One read returns four layers the frontend renders together on the
+ * admin calendar surface (`/admin/clients/calendar`):
+ *
+ *   1. events       — galleries from the `events` table. Blue solid.
+ *   2. hours        — customer_hour_entries. Green solid; greyed when
+ *                     locked (entry's invoice is past send/draft state).
+ *   3. quotes       — quotes that haven't been converted to an event yet,
+ *                     `status IN ('sent','accepted')`. Amber dashed.
+ *   4. contracts    — contracts that haven't been converted to an event
+ *                     yet, `status IN ('signed_by_customer','fully_signed')`.
+ *                     Purple dashed.
+ *
+ * Each item carries a `kind` discriminator so the frontend can union-type
+ * the response.
+ *
+ * **Access**
+ *
+ * Behind the `calendar` master feature flag (admin can disable globally
+ * via Settings → Features). Read permission is `customers.view` —
+ * mirrors the existing hour-entry list permission, since the calendar's
+ * primary mutation surface is hour entries and we want the same audience
+ * for read.
+ *
+ * **Range guard**
+ *
+ * `from` / `to` are required ISO date strings. We cap `to-from` at
+ * **90 days** so a misconfigured client (e.g. an infinite scroll that
+ * keeps expanding the range) can't trigger a multi-year scan. FullCalendar
+ * fetches month-by-month by default, so 90 days is a comfortable margin.
+ *
+ * **Drift guards**
+ *
+ * The `events.event_time_start / event_time_end / is_full_day` columns
+ * (migration 137) are read through `hasColumnCached` so un-migrated
+ * installs default to all-day rendering without 500-ing.
+ *
+ * **No mutations here**
+ *
+ * Hour-entry CRUD stays on the existing `/api/admin/customers/:id/
+ * hour-entries` routes (migration 129 + B.6 permission split). The
+ * calendar's drag-create / inline-edit modals call those directly.

+ * to source the sample PDFs, which leaked one customer's invoice to
+ * a different admin's inbox in multi-admin installs. The synthetic-

+ *
+ * The disk is the source of truth for restore. After a disaster
+ * (`docker compose down -v`, drive corruption, fresh install) the
+ * `backup_runs` table is empty — but the manifest JSONs are exactly
+ * what's left on disk for an admin to recover from. A wizard that
+ * only reads the DB shows "No backups found" precisely when the
+ * admin needs it most. So we walk first, dedupe-by-manifestId
+ * against any surviving DB rows, and present a unified list.
+ *
+ * Discovery rules:
+ *   - Walks `backup_destination_path` AND `backup_manifest_path` if
+ *     they're distinct (manifests can live in a sibling directory).
+ *   - Recurses up to 3 levels deep — enough to find
+ *     `<root>/manifests/backup-manifest-<id>.json` (the default
+ *     layout) without scanning the entire photo tree.
+ *   - Matches manifest files by glob: `backup-manifest-*.json`,
+ *     `backup-manifest-*.yaml`, and the legacy bare `manifest.json`.
+ *   - Parses each manifest to extract real metadata (timestamp,
+ *     size, file count, source type) instead of showing the admin
+ *     a list of opaque filenames.
+ *
+ * Returns: array of `{ type, name, path, manifestId, size,
+ * filesCount, completed, source: 'disk' | 'db' }`.

+ * Boot-time self-heal for the `backup_paths` table.
+ *
+ * **Why this exists**
+ *
+ * Knex won't re-run an applied migration, so once migration
+ * 109_add_backup_paths.js has run, any later default we want to add
+ * (a new subdirectory shipped by a future feature) would never reach
+ * already-deployed installs. The historical fix for this kind of
+ * "schema is fine, seed drifted" problem is the boot-time self-heal
+ * pattern documented in [[feedback_self_heal_pattern]] — we just
+ * re-apply the canonical seed on every boot with `onConflict.ignore()`
+ * so admin edits stay intact and new rows trickle in.
+ *
+ * **Authoritative list**
+ *
+ * The list of defaults lives on migration 109 itself
+ * (`DEFAULT_PATHS` export) — one source of truth that both the
+ * migration and this seeder read. Tests assert these two stay in
+ * lockstep.
+ *
+ * **Failure semantics**
+ *
+ * If the table doesn't exist yet (migrations haven't run, fresh
+ * install before migration 109 lands, etc.) we no-op and log. The
+ * walker has a hard-coded `LEGACY_DEFAULTS` fallback for the same
+ * reason — defense in depth so "Run Backup Now" can never silently
+ * ship a files-only manifest because of a seed issue. See
+ * `backupService.js` getFilesToBackupInternal.

+/**
+ * Install-from-backup boot hook.
+ *
+ * **The problem this closes**
+ *
+ * Without this hook, recovering a picpeak install from a backup is a
+ * six-step process:
+ *   1. Stand up the compose stack with empty volumes
+ *   2. Wait for boot → land on the onboarding wizard
+ *   3. Create a throwaway fresh-install admin
+ *   4. Navigate to Backup → Restore
+ *   5. Walk through the wizard with Force Restore ticked
+ *   6. Log out, log back in with original (pre-disaster) credentials
+ *
+ * With this hook, admins skip steps 2-6. They place their backup
+ * artefacts in the existing bind-mounted /backup directory, drop a
+ * trigger file alongside, and the next container start runs the
+ * restore BEFORE creating the throwaway onboarding admin. Server
+ * comes up populated, original login works first try.
+ *
+ * **The trigger file convention (chosen for zero compose-file changes)**
+ *
+ * Drop a file named `RESTORE_ON_INSTALL` (no extension, or .txt) into
+ * the root of the `/backup` mount. Two payload variants:
+ *
+ *   1. EMPTY file (or pure whitespace) — auto-pick the newest
+ *      `backup-manifest-*.json` from `/backup/manifests/`. Useful when
+ *      the admin doesn't know or care which one is most recent.
+ *
+ *   2. NON-EMPTY file containing a relative or absolute path to a
+ *      specific manifest. Trimmed; first line wins. Useful when the
+ *      admin wants a specific older backup.
+ *
+ * After a successful restore the trigger file is DELETED so the next
+ * boot doesn't re-trigger. On failure the file is preserved + the
+ * error is logged, so the admin can fix the input and retry by just
+ * restarting the container.
+ *
+ * **Safety**
+ *
+ * Three layers gate this against accidental data loss:
+ *   1. Trigger file must exist (intentional admin action, not auto-magic)
+ *   2. DB must be empty — admin_users.count = 0 AND events.count = 0.
+ *      If either is non-zero, the hook refuses to run.
+ *   3. The Stage A restore path (with all of tonight's fixes) handles
+ *      the actual swap atomically. If anything fails, the rollback
+ *      runs and the install stays in fresh-install state.
+ *
+ * Override: `INSTALL_FROM_BACKUP_FORCE=true` skips the empty-DB check
+ * for the "I know what I'm doing" edge case (e.g. dev environment
+ * rebuilds where there's leftover data that's safe to clobber).

+ * is a maintenance trap and any future renderer change relying on the
+ * raw string would fail surprisingly on one document type.
+ *
+ * Two helpers live here:
+ *
+ *   - `buildIssuerBlock(profile, resolvedLogoPath, options?)` — the
+ *     full issuer shape consumed by pdfService.drawIssuerBlock. Honors
+ *     the existing pdf_show_logo / pdf_show_company_name visibility
+ *     toggles, logo-height, folding-marks, etc. `options.quoteToggles`
+ *     adds the two quote-only fields (`quoteShowNetDays`,
+ *     `quoteShowSkonto`) — they are silently dropped for invoice and
+ *     contract callers so the same helper serves all three doc types.
+ *
+ *   - `buildRecipientBlock(profile, customer)` — the recipient address
+ *     block. Honors the maintainer spec: companies bold the company
+ *     name on line 1 + "z. Hd. <person>" on line 2; private customers
+ *     bold the person name on line 1 with no z.Hd. line at all. The
+ *     attentionLine string is always populated when a person+salutation
+ *     exists (the downstream renderer gates emission on hasCompany);
+ *     keeping the string non-empty preserves the back-pointer for
+ *     audit/debug surfaces that read the context directly.
+ *
+ * **What stayed in each service**
+ *
+ * Doc-type-specific fields (line items, totals, payment-term resolution,
+ * Skonto fallback chain, doc/title block, contract signatures + audit
+ * trail, source-quote line-items table) all stay where they are. Only
+ * the issuer + recipient blocks are extracted, since those are
+ * verbatim duplicates across all three services.

+/**
+ * Boot-time self-heal for restore-meta settings.
+ *
+ * **Why this exists**
+ *
+ * `restore_allow_force` gates whether the Restore wizard accepts a
+ * `force: true` payload. The flag exists to add admin friction
+ * before letting a restore override safety warnings (e.g. "1 active
+ * admin user — restoring would clobber the current install").
+ *
+ * In practice the friction lands at the worst possible moment: a
+ * fresh install (no app_settings row yet OR `restore_allow_force =
+ * false` by default) hits the wall on its very FIRST restore. The
+ * admin is mid disaster-recovery, panicked, and gets:
+ *
+ *   "Force restore is not allowed by system settings"
+ *
+ * They then have to hand-craft SQL like
+ *
+ *   INSERT INTO app_settings (setting_key, setting_value, ...)
+ *   VALUES ('restore_allow_force', 'true', 'restore', NOW())
+ *   ON CONFLICT ... SET setting_value = 'true';
+ *
+ * before they can recover their data. This isn't security — the
+ * admin who could run that SQL could also flip the setting via the
+ * UI. It's just a sharp edge that bites every new install once.
+ *
+ * Cure: seed the default ON at boot via `INSERT ... ON CONFLICT
+ * DO NOTHING`. New installs get force-allowed out of the box.
+ * Existing installs that have explicitly set the row (true OR
+ * false) are NOT overwritten — admin policy wins. Same pattern
+ * `_backupPathsBoot.js` uses for the canonical backup_paths rows.
+ *
+ * **Default-ON rationale (matches Stage A's principle)**
+ *
+ * Stage A defaulted inline DB dumps to ON because the cost of
+ * forgetting was data loss. By the same logic, `restore_allow_force`
+ * defaults ON because the cost of forgetting is being unable to
+ * recover from a disaster. Audit logging captures every forced
+ * restore so the accountability story stays intact.
+ *
+ * If/when the broader "exclude restore-meta settings from being
+ * overwritten by restore" follow-up lands (the second half of this
+ * chicken-and-egg), this self-heal becomes the safety net for
+ * fresh installs only — existing installs by that point have the
+ * row preserved across restores.

+ * because the whole reason Stage B exists is that the walker's
+ * subdirectory list used to silently fall behind reality every time
+ * a new feature dropped artefacts under STORAGE_PATH.
+ *
+ * This service answers two questions:
+ *
+ *   1. For every row in `backup_paths`, what will the next backup
+ *      do with it? (scan / skip-via-feature-flag / skip-via-toggle /
+ *      missing-on-disk)
+ *   2. What subdirectories EXIST under STORAGE_PATH but have NO row
+ *      in `backup_paths` — i.e. drift the admin should know about
+ *      before they lose data on a restore?
+ *
+ * Plus a top-level database-dump status block: are we configured
+ * for inline dump (default), or relying on the scheduled dump?
+ * When was the last successful dump? Is it stale?
+ *
+ * **What this service does NOT do**
+ *
+ *   - Does not run the backup
+ *   - Does not write anything (no DB mutations, no fs touches)
+ *   - Does not auto-recover drift (it's a diagnostic — admins decide
+ *     whether to add a `backup_paths` row, delete the orphan dir, etc.)
+ *   - Does not walk file contents — only top-level directory entries
+ *     under STORAGE_PATH are inspected (cheap; no recursion through
+ *     potentially-millions of photos)
+ *
+ * Read-only. Returns a JSON report — same shape as
+ * backupIntegrityService.verifyDocumentArtefacts.

+/**
+ * Backup-integrity verifier — walks every CRM document-artefact path
+ * column and confirms (a) the file exists on disk, (b) when a SHA-256
+ * is stored, the file's actual bytes hash to the stored value.
+ *
+ * **Why this is a separate service**
+ *
+ * The audit trail captured at issue / sign time (signed_customer_ip,
+ * signed_by_customer_at, signed_pdf_sha256, signed_*_signature_path,
+ * issue_date, etc.) is worth exactly nothing on its own — what makes
+ * it legally meaningful is being able to produce the document the
+ * audit trail refers to. A backup that captures the DB but skips
+ * `storage/business-docs/` (the bug fixed in this same PR) leaves
+ * every `*_path` column a broken FK and every `*_sha256` column with
+ * nothing to verify against. This service is the diagnostic for
+ * exactly that drift — runs on demand, surfaces missing files +
+ * hash mismatches without making any changes.
+ *
+ * **Verification modes**
+ *
+ *   - existence — file at `*_path` must exist on disk
+ *   - sha256    — file at `*_path` must exist AND its sha256 must
+ *                 equal `*_sha256` column (when that column is set)
+ *
+ * Per-table coverage (lines reference migrations/core/107_crm_consolidated.js):
+ *
+ *   quotes.pdf_path                            line 844   (existence)
+ *   contracts.pdf_path                         line 1245  (existence + sha256 via contracts.pdf_sha256)
+ *   contracts.signed_pdf_path                  line 1246  (existence + sha256 via contracts.signed_pdf_sha256)
+ *   contracts.signed_customer_signature_path   line 1269  (existence — drawn signatures, no hash column)
+ *   contracts.signed_admin_signature_path      line 1273  (existence — admin counter-signature drawing)
+ *   invoices.pdf_path                          line 1026  (existence)
+ *   invoices.imported_pdf_path                 line 1020  (existence — admin-uploaded scans)
+ *
+ * Wet uploads (`contracts.signed_pdf_is_wet_upload = true`) DO have a
+ * `signed_pdf_sha256` computed at upload time (contractService.js
+ * upload route), so they're hash-verified the same as system-rendered
+ * contracts — no special case here.
+ *
+ * **What this service does NOT do**
+ *
+ *   - Does not write anything (no DB mutations, no fs touches)
+ *   - Does not fail the request when a mismatch is found — the
+ *     report shape carries the data, the caller decides what to do
+ *   - Does not auto-trigger after restore (D2 decision: surface a
+ *     CTA on the restore-completed screen instead)
+ *   - Does not run on a schedule (D1 decision: on-demand v1; revisit
+ *     once we have runtime data on large installs)

+ *     marks the `backup_runs` row failed and queues the admin email
+ *

+ *
+ * Two tables back this:
+ *   - business_profile        singleton row (id=1) seeded by migration 102
+ *   - business_bank_accounts  1:N from business_profile
+ *
+ * Bank accounts are partitioned by currency: at most one default per
+ * currency. The Quote/Invoice editors auto-pick the matching default when
+ * the user changes the doc currency. The defaulting rule is enforced at
+ * the service layer (inside a transaction) — the DB doesn't have a
+ * partial unique index so we can't rely on it cross-dialect.

+/**
+ * contractService — orchestrates the lifecycle of `contracts`, their
+ * `contract_block_inclusions` (which blocks from the library make it
+ * onto a given contract), and the public `contract_action_tokens` used
+ * by the customer's signing link.
+ *
+ * Contracts are an INDEPENDENT document type alongside quotes and
+ * invoices. Composition model:
+ *   - Admin picks blocks from the `contract_blocks` library and toggles
+ *     them on/off per section (basics → scope → privacy → commercial →
+ *     nda → closing). Order within a section is admin-controlled.
+ *   - On send, every included block's body is FROZEN into
+ *     `body_text_snapshot` on the inclusion row, so future edits to
+ *     the source block don't mutate already-sent contracts.
+ *
+ * Signing:
+ *   1. Customer opens /contract/:token and either:
+ *      a) Types name, optionally draws a signature on canvas, ticks
+ *         "I have read and agree", submits → recordCustomerSignature
+ *         stamps the signature into a re-rendered PDF and the system
+ *         emails the admin.
+ *      b) Uploads a wet-signed PDF → attachSignedPdfUpload sets the
+ *         signed_pdf_path as the authoritative copy.
+ *   2. Admin counter-signs (in-browser or by re-uploading the
+ *      double-signed PDF) → status flips to `fully_signed`.
+ *
+ * Bodies support {{placeholders}} resolved at PDF/preview render time
+ * using the same Handlebars-lite regex that emailProcessor.safeTemplateReplace
+ * uses. We rebuild it inline here (not exported from emailProcessor) to
+ * keep the dependency tree shallow and so contracts can render
+ * client-side previews in the future without pulling the email
+ * processor.

+ * The consolidated migration (107_crm_consolidated.js) owns SCHEMA only;

+ *
+ * Same pattern as contractEmailTemplates.js + eventReminderTemplates.js
+ * — per the maintainer's "never ship compensation migrations" rule,
+ * we self-heal at runtime instead of bolting content into the schema diff.

+ *      → saving an entry immediately appends a line item onto the
+ *        running monthly draft (migration 128 accumulator) and flips
+ *        the entry to status='billed'. Admin doesn't have to remember
+ *        to convert; the running totals on the customer detail page
+ *        reflect the bill that will eventually go out.
+ *
+ *   2. Per-event customer + feature_hours_logging on
+ *      → entries sit at status='unbilled' until admin clicks
+ *        "Bill these hours" (billUnbilledEntries below). That call
+ *        mints a standalone invoice with one line per entry.
+ *
+ * Lockout: once an entry's invoice is "armed for send" (the monthly
+ * scheduler has cleared is_monthly_draft + set scheduled_send_at, or
+ * the invoice transitioned to sent/paid/cancelled), edits + deletes
+ * are refused. Admin must Storno the invoice to change billed hours

-  1. Ensure destination path has sufficient space
-  2. For large databases, backups may take significant time
-  3. PostgreSQL backups use single-transaction mode by default
-  4. Compression typically reduces size by 70-90%
-  5. Schedule backups during low-traffic periods
-  6. Monitor backup history for failures
-  7. Test restore procedures regularly
-  8. Consider replication for real-time redundancy

+/**
+ * eventReminderService — pre-event customer reminder emails
+ * (migration 143).
+ *
+ * Sends ONE reminder per event N days before `event_date`. Goal: nudge
+ * the customer on prep — space for equipment setup, dress-code notes,
+ * access logistics — so the photographer arrives to a workable scene.
+ *
+ * **Wiring**
+ *
+ * `runEventReminderPass()` is invoked from the invoice scheduler's
+ * hourly cron tick (commit #3 of this feature). Idempotent: every send
+ * stamps `events.event_reminder_sent_at`; subsequent ticks skip rows
+ * with a non-null timestamp.
+ *
+ * **Template resolution**
+ *
+ *   1. `event_reminder_<events.event_type>` — per-type template, if
+ *      seeded. Admin manages these via the existing email-template
+ *      editor (no schema rule restricts what they can create here;
+ *      whatever slug-prefixed templates exist will match).
+ *   2. `event_reminder_default` — catch-all, seeded by migration 143.
+ *
+ * Falls through silently when the catch-all is missing (logs a warn
+ * but doesn't throw — the cron must not crash the whole tick because
+ * of one stale install).
+ *
+ * **Override precedence per event**
+ *
+ *   - `events.event_reminder_disabled = true` → skip
+ *   - `events.event_reminder_offset_days` (nullable int) → overrides
+ *     the global `crm_event_reminders_days_before`
+ *   - `events.event_reminder_body_override` (text) → if set,
+ *     replaces the template body verbatim. Subject still comes from
+ *     the template. Useful for one-off "the venue has no loading zone,
+ *     arrive via the rear door"-style notes.
+ *
+ * **Recipient**
+ *
+ * Only the event's primary customer (`events.customer_account_id`).
+ * Multi-customer assignments via `event_customer_assignments` are NOT
+ * notified — confirmed with maintainer 2026-05-25. Events without a
+ * customer_account_id or without an email on file are skipped.
+ *
+ * **Snapshot semantics**
+ *
+ * We resolve + send eagerly per tick. The current shape stamps the
+ * sent_at timestamp on send — we deliberately do NOT snapshot the
+ * resolved body onto the event row at scheduling time, because the
+ * candidate window is short (N days before event) and the cron picks
+ * the freshest template every pass until the moment of send. If a
+ * future "schedule N hours ahead, freeze the body, send later" model
+ * is needed, add a snapshot column and resolve at scheduling time.

+/**
+ * Pre-event customer reminder templates — definitions + runtime self-heal.
+ *
+ * Migration 143 originally seeded an empty `event_reminder_default` row.
+ * That left admins staring at a blank editor and had no per-event-type
+ * variants. Per the maintainer's "never ship compensation migrations" rule
+ * (see contractEmailTemplates.js for the same pattern), we self-heal at
+ * runtime instead of bolting on a follow-up migration.
+ *
+ * `ensureEventReminderTemplatesSeeded(db, logger)` is idempotent — call
+ * it as often as you like:
+ *   - Missing template_keys get inserted with EN+DE example content.
+ *   - Existing template_keys whose EN translation is entirely empty
+ *     (the legacy migration-143 case) are backfilled with the example
+ *     content. Translations that already have any subject/body content
+ *     are LEFT ALONE so an admin's customisations never get clobbered.
+ *
+ * Process-level boolean caches the "all templates verified" state once
+ * we've made one successful pass, so the cron's hourly retick is free.
+ *
+ * Variables expected on every template: customer_name, event_name,
+ * event_date, event_type, days_before, business_name. Keep this list in
+ * sync with eventReminderService.composePayload.
+ *
+ * Per-type template keys (`event_reminder_<slug_prefix>`) are seeded for
+ * the four SYSTEM event_types from migration 061: wedding, birthday,
+ * corporate, other. Admins who add custom event_types via the Event
+ * Types settings page get no seeded body — they author their own via
+ * the Reminder Emails tab (the "Default" pill on the sidebar makes
+ * obvious which types are still riding the catch-all).

+/**
+ * Branded URL shortener for gallery share links (#699).
+ *
+ * Admins create `/s/<short_slug>` URLs that resolve to a gallery's full
+ * link AND answer social-crawler scrapes with the gallery's OG preview.
+ * The short URL is what photographers actually paste into chat — the
+ * og:url canonical points back at the short URL itself, so each social
+ * platform's cache is keyed on the slug the operator chose, not the
+ * underlying gallery URL that may rotate.
+ *
+ * Behaviour decisions worth pinning here (and in the migration comment):
+ *   - Soft-delete with `deleted_at` so an accidental delete is recoverable.
+ *     Public route serves 410 Gone (not 404) on a soft-deleted slug so
+ *     the admin sees their delete was intentional in scrapes/logs.
+ *   - Re-creating a soft-deleted slug rotates ownership: the old row is
+ *     hard-deleted, the new row is created. The UNIQUE constraint on
+ *     short_slug enforces this — you can't have two live rows for the
+ *     same public path.
+ *   - target_path is captured AT CREATE TIME from the event's current
+ *     state (slug + share_token + the global "Use short gallery URLs"
+ *     toggle). A later flip of that toggle doesn't silently change

+ *      `events.event_reminder_sent_at`.

+ * picpeak is NOT a double-entry ledger (that's Layer B). This service:
+ *   1. CRUD for `ledger_accounts` (Swiss/LI KMU-Kontenrahmen) + `vat_codes`,
+ *      plus the category→account and tax_treatment→VAT-code mappings.
+ *   2. buildPostings(): turns the data we already capture (revenue invoices,
+ *      incoming supplier invoices, internal expenses) into balanced
+ *      "Buchungssätze" — accrual-dated, single-row Soll/Haben entries with a
+ *      VAT code the target software expands.
+ *   3. Export formatters (generic / Banana / bexio) so a Treuhänder can import
+ *      the collective journal.
+ *
+ * Accrual basis only — payment/bank postings are Layer B (bank reconciliation).
+ * Legal/financial output is a GUIDELINE: every surface must point the user at a
+ * Treuhänder ([[feedback_legal_financial_examples_only]]).

+ *     yield working authenticator seeds;
+ *   - generate/verify one-time recovery codes, hashed (bcrypt) and single-use;
+ *   - build the otpauth:// URI + QR data-URL for enrollment.
+ *
+ * The encryption key is derived (scrypt) from MFA_ENCRYPTION_KEY when set,

+/**
+ * pdfService — render quote / invoice PDFs.
+ *
+ * Built on PDFKit + swissqrbill (the latter ships the SwissQRBill class
+ * for the QR-bill payment slip + a `Table` helper for the line items).
+ * Same engine renders both quotes and invoices — they differ only in
+ * title, lead-in text, optional Rabatt column (quotes only) and the
+ * QR-bill section (invoices only, when qr_format = 'swiss').
+ *
+ * Public API:
+ *   renderQuoteToBuffer(context)    → Promise<Buffer>
+ *   renderInvoiceToBuffer(context)  → Promise<Buffer>
+ *
+ * The caller (quoteService / invoiceService) hydrates the `context` from
+ * the DB and passes everything in — keeping pdfService a pure renderer
+ * makes both unit-tests and preview-from-form (no DB write) trivial.
+ *
+ * Money: every "*_minor" field is treated as INTEGER minor units
+ * (cents/Rappen) and rendered via Intl.NumberFormat using the supplied
+ * locale + currency.
+ *
+ * Layout reference: the user's existing Angebot / Rechnung templates
+ * (issuer block top-right, customer block left, "Datum" line, title,
+ * salutation + lead-in, line-item table, totals box right-aligned,
+ * payment conditions block, IBAN block, footer).

+ * Contract-PDF stamp service.
+ *
+ * Replaces the previous re-render-on-every-signature approach with
+ * the industry-standard pattern: the unsigned contract PDF is
+ * rendered once at send time and stays byte-immutable from then on.
+ * Each signature event opens that PDF with pdf-lib, overlays the
+ * signature PNG at the fixed coordinates defined in
+ * pdfService.CONTRACT_SIGNATURE_LAYOUT, then writes the result to a
+ * new timestamped file. Same model DocuSign / Adobe Sign / HelloSign
+ * use.

+ *   - No render-code drift between sign events; later layout
+ *     tweaks to renderContractToBuffer don't retroactively change
+ *     what already-signed PDFs look like.
+ *   - The audit certificate (timestamps, IPs, hashes) is a

+ * Compute line totals + document totals authoritatively from the
+ * supplied line items + VAT rate. Returns BigInt-safe integers (minor
+ * units). Discount is applied before VAT.
+ *
+ * Hierarchy rules (migration 119):
+ *   - Items with `parent_position` are SUB-ITEMS of the referenced
+ *     top-level item.
+ *   - Each sub-item's `line_total_minor` is computed (qty × unit ×
+ *     (1 − discount)) so the renderer can show its individual price
+ *     in parentheses for transparency.
+ *   - **Parent total auto-resolves from sub-items when any are
+ *     priced.** If at least one sub-item under a given parent has
+ *     `unit_price_minor > 0`, the parent's effective line_total is
+ *     the SUM of those sub-items' line_totals — the parent's own
+ *     stored unit_price is ignored. Mental model: when you list
+ *     itemised equipment with individual prices, the parent line
+ *     becomes a header that auto-totals what's under it.
+ *   - If all sub-items are priceless (transparency-only bullets), the
+ *     parent's own qty × unit × discount math stands as today.
+ *   - Sub-items NEVER contribute to the document net directly —
+ *     only the parent's effective line_total does. So sub-items
+ *     don't double-count, and the parent's "sum-of-sub-items" total
+ *     is what lands in net + VAT.
+ *
+ * The empty-payload check upstream ensures `lineItems` is always an
+ * array; we treat anything truthy on `parent_position` (number or
+ * string that parses to int) as "I'm a sub-item".

+      // restart" — but that left the running process serving a

+      // Not acceptable per the "backup must restore completely even

+      // is untouched). Idempotent — migrations already applied are
+      // tracked in the restored `migrations` table and get skipped.

+ * taxReportService — period-scoped revenue listing for tax filing.
+ *
+ * Pulls every revenue-relevant invoice in [from, to] (accrual basis,
+ * keyed on `issue_date`) and returns rows + totals broken down by
+ * VAT rate. Cancelled invoices stay in the row list (DE/CH/AT audit
+ * trail requires a gap-free invoice-number sequence) but are excluded
+ * from the totals math.
+ *
+ * Late fees: the user opted to include them in the totals. We split
+ * each invoice's `late_fee_amount_minor` proportionally using the
+ * invoice's own VAT rate:
+ *   lateFeeNet = round(late_fee_amount_minor / (1 + vat_rate/100))
+ *   lateFeeVat = late_fee_amount_minor − lateFeeNet
+ * and add those onto the stored `net_amount_minor` / `vat_amount_minor`
+ * before reporting. Invoices without a late fee → math collapses to
+ * the stored values.
+ *
+ * Returned shape (see getTaxReport):
+ *   {
+ *     rows:               [{ id, invoiceNumber, issueDate, currency,

+ *                referrerpolicy, data-*
+ *   <noscript> — no attributes
+ *   <link>     — rel (preconnect/dns-prefetch only), href, crossorigin
+ *   <meta>     — name, content, charset
+ *
+ * Anything else is stripped. Inline script bodies pass through unchanged
+ * (the tracker's bootstrap snippet is the whole point), but we DO normalise
+ * URL schemes — `javascript:` / `data:` URLs on `src` / `href` are removed.

+/**
+ * Rybbit metrics-API adapter (#663 Phase 1).
+ *
+ * Rybbit is a self-hosted privacy-friendly analytics product (https://rybbit.io).
+ * Reporter @alexvaltchev specifically asked for it in #661 follow-up, hence
+ * its inclusion as the second native adapter alongside Umami.
+ *
+ * Contract: matches `umamiAdapter` exactly so the dashboard route can call
+ * either via the factory.
+ *
+ * Auth: Rybbit v1 issues per-account API keys (Account → Settings → API
+ * Keys). Sent via `Authorization: Bearer <key>`. Their docs at
+ * https://rybbit.io/docs/api describe the analytics endpoints.
+ *
+ * Endpoint shape (Rybbit v1 stats API, devices breakdown):
+ *
+ *   GET {baseUrl}/api/site/{websiteId}/breakdown
+ *     ?dimension=device
+ *     &start={iso8601-or-epoch-ms}
+ *     &end={iso8601-or-epoch-ms}
+ *
+ * Returns rows like `[{ device: 'desktop', visitors: 123, sessions: 456 }, …]`.
+ * We aggregate `sessions` into the same 3-bucket shape Umami returns.
+ *
+ * Per-bucket naming: Rybbit reports `desktop` / `mobile` / `tablet`
+ * directly (matches our UI). Anything unrecognised is dropped rather than
+ * silently miscategorised.
+ *
+ * NOTE: Rybbit's API is on v0.x at the time of writing. The endpoint /
+ * dimension names below match the documented v1 GA shape; if a tester
+ * confirms a deviation in the wild we adjust here, and the rest of the
+ * codebase keeps working because the adapter returns null on shape
+ * mismatch (route falls back to access_logs).

+ * address they were given — see #574.

+ * Use this options object on every `.normalizeEmail()` call. The only

+ * safe — local-parts are case-insensitive in practice on every major
+ * provider, and lowercasing keeps login lookup consistent.

+ *
+ * What this enforces:

+ *   2. **Expiry**            — 410 when `expires_at` is in the past

+ *                              not "valid forever" — historical bug).
+ *   3. **One-shot semantics** — when `requireUnused: true`, 409 if
+ *                              `used_at` is already set. Prevents
+ *                              replay of leaked tokens on the upload

+ *                              per call site.
+ *   4. **Attempt throttling** — non-existent tokens increment a per-IP
+ *                              counter; the IP is locked out for 15 min
+ *                              after 20 invalid attempts. Mitigates the

+ * resolveLogoFile — resolve a logo to an absolute existing file path.
+ *
+ * The CRM PDFs accept a logo from three different sources and each
+ * source may store the path in a different shape (absolute multer
+ * path, relative URL, bare filename, etc.). Rather than have the PDF
+ * renderer guess, we build an exhaustive candidate list HERE, return
+ * the first existing PNG/JPEG file, and log everything we tried when
+ * we come up empty.
+ *
+ * Why this lives in utils:
+ *   - both invoiceService and quoteService need the same resolution
+ *   - the renderer (pdfService) should NOT touch the DB or the
+ *     filesystem-discovery rules; it just calls doc.image(path)
+ *
+ * Sources we accept (in priority order):
+ *   1. business_profile.logo_path  — explicit per-CRM logo
+ *   2. app_settings.branding_logo_path  — absolute multer path from
+ *      Settings → Branding (preferred — already absolute)
+ *   3. app_settings.branding_logo_url   — URL path from the same
+ *      branding upload (fallback for older installs)
+ *
+ * For each source we try multiple candidate disk paths:
+ *   - The raw value as an absolute path (if absolute)
+ *   - STORAGE_PATH joined with the value (stripped of leading "/")
+ *   - STORAGE_PATH/uploads/logos/<basename>
+ *   - STORAGE_PATH/branding/<basename>
+ *   - CWD/storage joined with the value (last-ditch for older
+ *     docker-compose configs that didn't set STORAGE_PATH)
+ *
+ * Format filter:
+ *   PDFKit only natively decodes PNG + JPEG. SVG/WebP/GIF/TIFF files
+ *   are silently skipped here (with a warn log) so the rest of the
+ *   PDF still renders rather than crashing on an unsupported format.

+/**
+ * safePath — path-containment helpers for the contract / quote / invoice
+ * PDF surfaces.
+ *
+ * **Why this exists**
+ *
+ * The audit (#25, #31) flagged that several routes pipe `fs.createReadStream`
+ * on a path read directly from the DB (`contracts.pdf_path`,
+ * `contracts.signed_pdf_path`) and that `attachSignedPdfUpload` accepts
+ * a route-supplied filePath with no containment assertion. The
+ * defence-in-depth concern: if a path ever got into the DB pointing
+ * outside the legitimate storage roots (via a future migration bug,
+ * a hand-edited row, or a SQL-injection regression elsewhere), the
+ * stream would happily read /etc/passwd or any other readable file
+ * for the requesting admin.
+ *
+ * Today the DB paths are written by the service layer and never
+ * accept caller input directly, so the practical exposure is low —
+ * but a 4-line containment check at the read boundary makes the
+ * invariant explicit and protects against future drift.
+ *
+ * **Approach**
+ *
+ * `assertPathInside(absoluteFilePath, allowedRoots)` resolves both
+ * sides to canonical absolute paths via `fs.realpathSync` and
+ * verifies the file path starts with one of the allowed root strings
+ * followed by a path separator (so /storage-evil/ doesn't pass when
+ * /storage/ is allowed). Throws `AppError 403` on violation.
+ *
+ * `realpathSync` resolves symlinks, defeating the obvious attack
+ * (symlink in storage root → /etc/passwd). It throws on missing
+ * files, which is fine — callers already exists-check before stream
+ * via `fs.existsSync`. We re-throw missing-file errors as
+ * AppError 404 to keep the response shape consistent.
+ *
+ * **What the contract surface uses**
+ *
+ * Two roots:
+ *   1. `<cwd>/storage/business-docs/contract/<year>/` — system-stamped
+ *      PDFs (immutable as-sent + signed copies).
+ *   2. `<STORAGE_PATH or cwd/storage>/uploads/contracts/signed/` —
+ *      wet-upload PDFs (admin or customer-supplied).
+ *
+ * Both roots are constants from the operator's perspective; legitimate
+ * paths always live under one of them.

+/**
+ * schemaCache — process-local memoisation for `db.schema.hasColumn`.
+ *
+ * **Why this exists**
+ *
+ * The CRM services on `feat/crm` are riddled with `hasColumn` guards
+ * because the schema has been drifting fast (every doc-feature
+ * migration adds a column that older installs may not yet have).
+ * Each call hits information_schema (Postgres) or sqlite_master
+ * (SQLite). On hot paths — `recordCustomerSignature`,
+ * `recordAdminCountersignature`, `getContractById`, the monthly
+ * billing pass — we issue 4–8 hasColumn checks per request, all
+ * for columns whose presence cannot change at runtime.
+ *
+ * The audit flagged this as a perf medium. Caching is safe because:
+ *
+ *   1. Schema-changing operations (migrations, `ALTER TABLE`) only
+ *      run at boot via `run-migrations-safe.js`, BEFORE any service
+ *      module accepts traffic. The cache is populated lazily after
+ *      boot finishes, so the entries reflect post-migration state.
+ *
+ *   2. The Node process is the only schema authority. There's no
+ *      sibling process sneaking in `ALTER TABLE` while we serve
+ *      requests.
+ *
+ *   3. If a future migration path needs to run mid-flight, it can
+ *      call `invalidateSchemaCache()` after the schema change.
+ *
+ * **What we cache**
+ *
+ * Just the boolean answer to `(table, column)`. A miss means the
+ * column doesn't exist on this install; a hit means it does. The
+ * cache key is `${table}.${column}`. There's no TTL — the entry is
+ * valid for the lifetime of the Node process.
+ *
+ * **What we DON'T cache**
+ *
+ * Negative results from `hasTable` failures (the table simply isn't
+ * there) — those go through the underlying call each time. That
+ * scenario is exceptional (table truly missing during a half-applied
+ * migration window) and we want it to surface, not get masked by a
+ * stale cache.

+# Accounting — Incoming invoices, expenses & re-bill
+
+> **Status:** built on `feat/accounting-inbound-invoices` (based on `upstream/beta`); not yet merged to `main`.
+> **Legal:** every VAT / tax-treatment surface is an *example only* and must be reviewed with a Treuhänder before relying on it. Jurisdiction scope is **Liechtenstein-first** (Swiss/LI rails — QR-bill, LI MWST), not German DATEV/ELSTER/ITSG. See `docs/crm-disclaimers.md`.
+
+## Why
+The studio receives supplier invoices/receipts (hotels, equipment, Fremdleistungen). This feature lets an admin **capture** an incoming invoice (upload, **phone/tablet camera**, or **IMAP email intake**), confirm its fields, give it a **disposition**, mark the **supplier payable** paid, and — for client-borne costs — **re-bill it to a client** ("Weiterverrechnung"), consolidated onto the client's bill the same way billable hours are.
+
+## Two distinct entities (split in migration 126)
+Incoming invoices and internal expenses are **separate** — one document never appears in both surfaces.
+
+- **Incoming invoices** (`inbound_documents`) — an *external* supplier document. The **row itself is the payable**: it carries the disposition, tax treatment, event booking, re-bill linkage, supplier-payment, note, and (for re-bills) the attached customer. Categorising it **updates the document** — it never derives an `expenses` row. Mark-paid lives here.
+- **Expenses** (`expenses`, `inbound_document_id IS NULL`) — *internal* own-costs: `kind = amount | mileage | per_diem` (amount = quantity × rate, rate from accounting settings with per-entry override), optional proof file, booked to an event or the company. Disposition is always `eigener_aufwand`; no supplier payment.
+
+This document covers the **incoming-invoices** surface. Expenses share the markup/re-bill helpers but are otherwise independent.
+
+## Lifecycle
+```
+capture (upload / camera / email)
+   → inbox row, status = unsorted, parse_status = pending
+triage (confirm fields + disposition + note)
+   ├─ eigener_aufwand → company expense (pick category), booked to company
+   ├─ durchlaufend    → pass-through; optionally attach a client (billed at cost)
+   ├─ rebill          → re-bill to a client (with markup)
+   ├─ duplikat        → status = duplicate (excluded from the books)
+   └─ abgelehnt       → status = declined (excluded from the books)
+supplier payment (independent axis): markInboundSupplierPayment → supplier_paid
+```
+
+### Dispositions
+Five: `rebill` · `durchlaufend` (Durchlaufender Posten) · `eigener_aufwand` (company expense) · `duplikat` · `abgelehnt`.
+
+- **`rebill`** — your own supplier cost, invoiced on to a client, usually with a **markup** (percent or flat). Requires a customer.
+- **`durchlaufend`** — an amount fronted on behalf of a client and passed through **at cost / VAT-neutral**. May optionally attach a client (then it is re-billed like a rebill, but **never carries a markup** — enforced in both the UI and `categorizeInbound`). With no client it is only booked to an event/company.
+- **`eigener_aufwand`** — own cost, not re-billed; pick an expense category for the Erfolgsrechnung.
+
+The triage modal shows an **inline explainer** for the selected disposition (`accounting.disposition.help.*`) and a **note** field on every disposition.
+
+### Re-categorisation
+Categorising is **re-runnable** — a categorised invoice can be changed again (e.g. pass-through → company expense), including after the supplier has been paid (supplier-payment and classification are independent axes). When the document was already re-billed, `categorizeInbound` first **unwinds** the prior re-bill line (removes the invoice line, recomputes the invoice totals) before applying the new disposition. It **refuses** (`INVOICE_LOCKED`) only when the re-bill sits on an already-issued invoice — then a Storno is required (`isInvoiceMutable` mirrors the hour-entry lock rules). The only hard lock is an *issued* invoice, never supplier-payment.
+
+### Re-bill: cadence-aware, like hours
+Re-bill/pass-through-to-a-customer consolidates onto the client's bill exactly like `customerHoursService`:
+
+- **Monthly / manual customers** — the line is appended **immediately** onto the customer's running monthly draft (via `invoiceService.createInvoice`'s accumulator intercept). `billed_invoice_id` is set at categorise time.
+- **Per-event customers** — the item stays **PENDING** in the customer's pool (`customer_account_id` set, `billed_invoice_id` null). The inbox surfaces a **"Pending re-bills"** card grouped by customer; **"Bill these"** (`billPendingRebills`) bundles all of a customer's pending items into **one** invoice (one line per document), then navigates to the bill editor so the admin can add more lines before sending. This mirrors `billUnbilledEntries`.
+
+Markup resolution (rebill only): expense/document override → contract `Spesen-Zuschlag` clause → 0% (`resolveMarkup`). The re-bill line description is `"{supplier} (Weiterverrechnung)"` / `"… (Durchlaufende Position)"`.
+
+## Data model (migrations 122–132)
+All money is integer minor units (`*_amount_minor`). Additive, hasTable/hasColumn-guarded.
+
+- **122** — seed `accounting` master flag (default OFF; preserve-visuals auto-enable where `taxReport` was on).
+- **123** — `accounting.view` / `accounting.manage` permissions.
+- **124** — `inbound_documents`, `expenses`, `expense_categories` (+ seed categories).
+- **125** — contract `expense_markup_type|_percent|_flat_minor` (Spesen-Zuschlag clause).
+- **126** — split incoming vs expenses: disposition/tax_treatment/event_id/category_id, re-bill markup + `billed_invoice_id`/`billed_invoice_line_item_id`, supplier-payment columns on `inbound_documents`; `kind`/`quantity`/`rate_minor` on `expenses`.
+- **127** — separate `expenses` sub-flag + accounting `app_settings` (km/per-diem rate, require-proof). *(NB: `app_settings` has no `created_at/updated_at` — seed `setting_key/value/type` only.)*
+- **128** — incoming mail (IMAP): `incomingMail` flag + `email_configs.imap_*` + `received_emails`.
+- **129** — `ledger_accounts` + `vat_codes` (Swiss/LI KMU seed) + category→account mapping.
+- **130** — `vat_code` snapshot column on quotes + invoices.
+- **132** — `inbound_documents.note` + `inbound_documents.customer_account_id` (the attached re-bill client; loose link, indexed for the pending-pool lookup).
+
+`inbound_documents` key columns: parsed fields (`supplier_name`, `invoice_date`, `total/net/vat_amount_minor`, `iban`, `payment_reference`) + separate untrusted `qr_amount_minor` (tamper cross-check — the authoritative total is the text value); `status` (unsorted/categorized/declined/duplicate); `disposition`; `tax_treatment`; `event_id` (NULL = company); `category_id`; `customer_account_id`; `markup_type/_percent/_flat_minor`; `billed_invoice_id` + `_line_item_id`; `supplier_paid` + `_at/_method/_ref`; `note`.
+
+## API (`/api/admin/expenses`, gated by `incomingInvoices` + `accounting.*`)
+- `POST /inbound` (multipart) — capture (upload/camera). Deduped by SHA-256.
+- `GET  /inbound` — list (joins the attached customer name/email).
+- `GET  /inbound/pending-summary` — per-customer pending re-bills (registered before `/inbound/:id`).
+- `POST /inbound/bill-pending` — bundle one customer's pending re-bills into one invoice.
+- `GET  /inbound/:id` · `PATCH /inbound/:id` (edit/confirm fields incl. `note`).
+- `GET  /inbound/:id/page/:n` — rasterised PNG of a page. `GET /inbound/:id/file` — original (PDFs as attachment only, never inline).
+- `POST /inbound/:id/categorize` — set disposition (re-runnable; unwinds prior re-bill).
+- `POST /inbound/:id/rebill` — explicit "re-bill this one now" (forces an immediate single-doc bill).
+- `POST /inbound/:id/supplier-payment` — toggle supplier paid + method/date/reference.
+- Expenses: `GET/POST /`, `GET/PATCH /:id`, `POST /:id/invoice`, `POST /:id/paid`, `GET /:id/proof`.
+- Categories: `GET/POST/PATCH/DELETE /categories` (accounting master).
+
+## Document preview = server-side rasterised images
+Raw PDFs are **never** served inline. `rasterizeService` shells out to poppler `pdftoppm` (OS package in the Docker image — not a Node PDF lib, runs no JS, no egress). Pages cached under `storage/business-docs/inbound/rendered/<id>/page-<n>.png`, served with `Content-Security-Policy: default-src 'none'` + `nosniff`. Page count capped at 200. The triage preview defaults to the last page (the Swiss QR-bill usually sits at the bottom).
+
+## Reporting & export
+- **Tax report** (`taxReportService`) — full Einnahmen-Ausgaben: incoming invoices + expenses feed the `costs` side, grouped Company vs Event; re-billed costs are kept (the matching re-bill revenue is also counted, so it nets). `vatPayable` = output VAT − reclaimable input VAT (excludes `foreign_vat_non_reclaimable`); zero when not VAT-registered. Gated on `accounting` + `taxReport` (no longer `bills`).
+- **Treuhänder export** (`ledgerService`) — accrual Buchungssätze → generic/Banana/bexio CSV. Accrual basis only; bank/payment postings are Layer B (deferred). See `project_banana_treuhaender_export_format`.
+- VAT config (codes, rate→code + treatment→code maps, registration & reclaim countries, chart of accounts) lives under **Settings → Accounting**; invoices snapshot the chosen `vat_code`.
+
+## Flag model
+`accounting` is an explicit top-level **master** flag with sub-toggles: `incomingInvoices` (this surface), `expenses` (internal expenses), `taxReport` (moved permanently out of CRM, now independent of `bills`). `incomingMail` (IMAP) is a separate flag, not under accounting. `accounting` off forces `taxReport` + `incomingInvoices` off.
+
+## Conventions followed
+Idempotent migrations; new flags default OFF; flag reads tolerate `true|1|'1'`; money as integer `*_minor`; `requirePermission` guards; camelCase API ↔ snake_case service; multer + `safePath` containment at every file boundary; localized dates via `useLocalizedDate`; money via `utils/money`; every tax/legal surface carries a "verify with your Treuhänder" disclaimer.
+
+## Deferred
+- **OCR / auto-extract** — `extractionService` is a no-op stub (Tesseract + Swiss-QR decode); admin reads the slip and types the fields.
+- **Capture-time VAT reclaim default** — `accounting_vat_reclaim_countries` is stored but not yet consumed; needs a `supplier_country` column to default `tax_treatment`.
+- **Bank reconciliation** — match incoming payments to open invoices / confirm supplier invoices paid (LLB DataFeed / camt.053 / EBICS). Phased, Swiss/LI rails.
+- **Native double-entry (Layer B)** — picpeak stays a feeder/export tool below the CHF 500k threshold; full Erfolgsrechnung/Bilanz is out of scope.

+title: Backup & Restore
+description: How picpeak captures your install, where backups land, and how to recover from them — including full disaster recovery.
+sidebar_position: 2
+---
+
+# Backup & Restore
+
+picpeak's backup system captures your entire install — database, photos, CRM documents, gallery archives, and configuration — to a destination of your choice. Recovery happens through one of two paths depending on how badly things went wrong:
+
+- **The install is alive** → use the **Restore wizard** in the admin UI to roll back to a chosen backup.
+- **The install is gone** (host migration, `docker compose down -v`, drive replacement) → use the **install-from-backup** trigger file convention to rebuild in one boot, with no onboarding wizard and no temporary admin step.
+
+This guide covers both.
+

+
+## What gets backed up
+
+Every "Run Backup Now" (manual or scheduled) produces:
+
+1. **A database dump** captured inline at the start of the run. Always included by default. picpeak refuses to ship a backup without a database dump unless the operator has explicitly opted out via the `backup_database_inline_dump` setting — see [Inline DB dump](#inline-db-dump) below.
+
+2. **Files from a configurable list of paths**, declared in the `backup_paths` table:
+   | Path | Default | Notes |
+   | --- | --- | --- |
+   | `events/active` | ✓ | Live gallery photo originals |
+   | `events/archived` | gated by `backup_include_archived` | Long-term archive |
+   | `thumbnails` | ✓ | Generated thumbnails |
+   | `previews` | ✓ | Lightbox preview tier |
+   | `heroes` | ✓ | Gallery hero images |
+   | `uploads` | ✓ | Wet-signature contracts, imported invoices, etc. |
+   | `business-docs` | ✓ | CRM PDFs, signature artefacts, imported historical invoices |
+
+   Admins can add or remove rows from `backup_paths` to teach the walker about new feature directories — see [Custom backup paths](#custom-backup-paths).
+
+3. **A manifest JSON** describing the run, written to `<destination>/manifests/backup-manifest-<id>.json`. The manifest carries the database dump path, the file inventory, checksums, and per-path counters.
+
+## Destinations
+
+picpeak supports three destination types, configured via **Backup → Configuration**:
+
+- **Local** — files copied to a directory on the same host (default: `/backup` inside the container, which is typically a bind mount).
+- **S3 / MinIO** — files uploaded via the S3 API. Supports custom endpoints (for MinIO, Backblaze B2, Wasabi, etc.).
+- **rsync** — synchronised to a remote host over SSH.
+
+Direct download from the admin UI is supported for local destinations; S3 backups can be retrieved via pre-signed URLs.
+
+## Inline DB dump
+
+Every "Run Backup Now" runs `pg_dump` (or `sqlite3 .backup`) inline before walking files. This guarantees the manifest's `database.backup_file` is always a fresh capture, never a stale reference to a previously-scheduled dump that may not exist.
+
+If the inline dump fails (disk full, pg_dump crash, permission error), the run aborts and writes the error to `backup_runs.error_message`. The UI surfaces this as a failed run — no more silent files-only manifests.
+
+**To opt out** (e.g. if you have a separately-orchestrated DB backup that you trust more):
+
+```sql
+INSERT INTO app_settings (setting_key, setting_value, setting_type, updated_at)
+VALUES ('backup_database_inline_dump', 'false', 'backup', NOW())
+ON CONFLICT (setting_key) DO UPDATE
+  SET setting_value = 'false', updated_at = NOW();
+```
+
+With inline-dump opted out, picpeak's fail-loud guard still applies: a file backup with no recent DB dump on file (within 26 hours) will fail rather than ship a files-only manifest.
+
+## Custom backup paths
+
+To add a new directory to the backup walker (e.g. you've shipped a feature that drops artefacts under `storage/my-feature/`):
+
+```sql
+INSERT INTO backup_paths (path, include_in_default, display_order, description, created_at, updated_at)
+VALUES ('my-feature', true, 100, 'My new feature artefacts', NOW(), NOW());
+```
+
+Next "Run Backup Now" picks it up — no restart, no migration. Set `include_in_default = false` to temporarily disable a path without dropping the row.
+
+The `feature_flag` column gates a path behind an app_settings boolean (matches how `events/archived` is gated by `backup_include_archived`). Useful when a backup path corresponds to an optional feature.
+
+## The Coverage tab
+
+**Backup → Coverage** answers "what will the next backup actually include?" without having to run it:
+
+- **Database** — inline-dump mode + last dump timestamp + staleness check
+- **Configured paths** — one row per `backup_paths` entry with its current coverage status (`will-scan` / `skipped-by-toggle` / `skipped-by-feature-flag` / `missing-on-disk`)
+- **Drift detection** — flags top-level directories under `STORAGE_PATH` that exist on disk but have NO matching `backup_paths` row. This is the canary for "a feature shipped without a matching backup row" — the most common cause of silent data loss in pre-2026-05 picpeak.
+
+The Coverage tab auto-fetches on open. If everything is green, your next backup will capture what you'd expect.
+
+## The Integrity tab
+
+**Backup → Integrity** verifies that every `*_path` column on quotes / contracts / invoices / signatures actually resolves to a file on disk, AND that files with a stored `*_sha256` still hash to the same value. Read-only, on-demand. Useful for:
+
+- Post-restore validation
+- Detecting bit-rot
+- Auditing legal-evidence artefacts before a tax review or dispute
+
+## Restoring on a live install
+
+Use this when picpeak is running and you want to roll back to a specific backup point — e.g. recovering accidentally-deleted records, reverting a bad migration, or testing a restore drill.
+
+**Backup → Restore** walks you through:
+
+1. **Source** — Local, S3, or rsync
+2. **Choose Backup** — manifests discovered from disk (works after a fresh install where `backup_runs` is empty) or from the database history
+3. **Restore Options** — Full / Database only / Files only / Selective + Force + Skip Pre-Restore
+4. **Review** — surfaces validation warnings before you commit
+5. **Restore Progress** — real-time stream of the actual steps
+
+Failures during restore trigger an automatic rollback from the pre-restore safety snapshot. The destination ends up either as the restored state OR as the original pre-restore state — never as a half-clobbered mix.
+
+### Restoring an older backup on a newer image
+
+picpeak's restore path is forward-compatible: a backup taken on an older version restores cleanly onto a newer image without any manual schema work. After loading the dump, the restore service runs the same `npm run migrate:safe` script that `wait-for-db.sh` uses on every container boot. Any migrations that have been added between the backup's snapshot and the current image are applied inline, against the freshly-restored DB, before the restore is reported as complete.
+
+Net effect: even if `bugfix/cool-new-feature` shipped a migration that adds a `widgets` table and your backup predates that branch, after restore your install has the `widgets` table (empty), the right indexes, and any seed rows the migration emits. No "you'll need to restart the container once" footnote.
+
+The same applies to the install-from-backup trigger — migrations land inside the restore boundary, so the moment the server prints `Server running on port 3000`, the schema matches the running image. Log in and use the install immediately.
+
+## Disaster recovery (install from a backup)
+
+For full DR after `docker compose down -v`, host migration, drive replacement, or moving an install between hosts. picpeak detects a trigger file on first boot and runs the restore before the admin UI surfaces. You open the browser, log in with your original credentials, and the install is fully populated.
+
+### Prerequisites
+
+- Your install's backup files must already be present in the `/backup` mount. They survive `docker compose down -v` because `/backup` is a bind mount, not a Docker-managed volume.
+- The image must include the install-from-backup feature (shipped 2026-05-31 on `beta`; available in `main` after the next stable release).
+- The backup must contain a database dump. The wizard cannot reconstruct your CRM data, customers, quotes, invoices, or admin users from a files-only backup. Confirm by inspecting any `backup-manifest-*.json` and checking that `database.backup_file` is non-null.
+
+### How the trigger works
+
+On every container start, picpeak's boot sequence checks for a trigger file in the root of the `/backup` mount. If found AND the destination database is empty, the restore runs automatically. After a successful restore the trigger file is deleted so the next boot doesn't redo the work. On failure the trigger file is preserved — fix the input and restart the container to retry.
+
+The trigger file is named **`RESTORE_ON_INSTALL`** (no extension) or **`RESTORE_ON_INSTALL.txt`** — either is accepted.
+
+### Two trigger flavors
+
+#### Auto-pick the newest backup
+
+Create an empty trigger file:
+
+```sh
+touch /path/to/backup/RESTORE_ON_INSTALL
+```
+
+The boot hook will scan `/backup/manifests/` for files matching `backup-manifest-*.json` (or `.yaml`) and pick the one with the most recent modification time. Best for the common DR case where you simply want the latest snapshot.
+
+#### Use a specific backup
+
+Write the path of the manifest you want — either relative to the `/backup` mount root or an absolute path — into the trigger file:
+
+```sh
+# Relative path (recommended)
+echo "manifests/backup-manifest-backup-20260530-190617-e9be97b3.json" \
+  > /path/to/backup/RESTORE_ON_INSTALL
+
+# Or absolute path inside the container
+echo "/backup/manifests/backup-manifest-backup-20260530-190617-e9be97b3.json" \
+  > /path/to/backup/RESTORE_ON_INSTALL
+```
+
+Use this when you need to restore an older backup (e.g. rolling back a data corruption that happened after the most recent backup ran).
+
+### Full DR walkthrough
+
+```sh
+# 1. Snapshot the backup outside the compose directory (belt + suspenders).
+#    This is a docker-compose-down-v-proof copy in case anything goes wrong.
+SNAPSHOT=~/picpeak-snapshots/$(date +%Y%m%d-%H%M%S)
+mkdir -p "$SNAPSHOT" && cp -av /path/to/picpeak/backup/. "$SNAPSHOT/"
+
+# 2. Verify the backup is restorable. database.backup_file must be non-null.
+LATEST=$(ls -t /path/to/picpeak/backup/manifests/*.json | head -1)
+docker compose exec backend cat "/backup/manifests/$(basename $LATEST)" \
+  | python3 -c "import json,sys; m=json.load(sys.stdin); \
+      print('DB included:', bool(m.get('database',{}).get('backup_file')))"
+
+# 3. Drop the trigger file. Two variants — pick one:
+
+# (a) auto-pick newest
+touch /path/to/picpeak/backup/RESTORE_ON_INSTALL
+
+# (b) specific manifest
+echo "manifests/backup-manifest-backup-20260530-190617-e9be97b3.json" \
+  > /path/to/picpeak/backup/RESTORE_ON_INSTALL
+
+# 4. Boot.
+docker compose down -v
+docker compose up -d
+docker compose logs -f backend --tail=100
+```
+
+When the boot log shows `Install-from-backup: restore completed successfully` followed by `Server running on port 3000`, the install is ready. Open the admin UI and log in with your original (pre-disaster) credentials.
+
+### Safety gates
+
+Three layers prevent accidental data loss:
+
+1. **The trigger file must exist.** No auto-magic — an admin explicitly drops the file to signal intent.
+
+2. **The destination database must be empty.** If the database contains any events, the install-from-backup hook refuses to run. The fresh-install default admin (auto-created by migration 001) is treated as throwaway and replaced by the backup's admin row, so a single admin user does not block the restore.
+
+3. **Failed restores roll back to the pre-restore state.** If anything fails after the DROP DATABASE step, picpeak's automatic rollback restores the destination from the pre-restore safety backup it took before starting.
+
+#### Override for advanced cases
+
+If you have a populated install you intentionally want to clobber (dev rebuilds, staging refresh, etc.):
+
+```yaml
+# In docker-compose.yml
+backend:
+  environment:
+    - INSTALL_FROM_BACKUP_FORCE=true
+```
+
+Or via the CLI:
+
+```sh
+INSTALL_FROM_BACKUP_FORCE=true docker compose up -d backend
+```
+
+With this set, gate #2 is skipped and the restore proceeds even with existing data. Gates #1 (trigger file presence) and #3 (rollback on failure) still apply.
+
+### Verifying DR success
+
+After the boot log shows `Install-from-backup: restore completed successfully`:
+
+```sh
+# Trigger should be gone (deleted on successful restore)
+ls /path/to/picpeak/backup/RESTORE_ON_INSTALL 2>/dev/null \
+  || echo "Trigger cleaned up — restore succeeded."
+
+# Inspect the restore_runs row
+docker compose exec -T postgres psql -U picpeak -d picpeak_prod -c \
+  "SELECT id, status, was_successful, was_rollback_attempted FROM restore_runs ORDER BY id DESC LIMIT 1;"
+
+# Confirm data is back
+docker compose exec -T postgres psql -U picpeak -d picpeak_prod -c "
+  SELECT 'admin' AS t, COUNT(*) FROM admin_users
+  UNION ALL SELECT 'events',       COUNT(*) FROM events
+  UNION ALL SELECT 'invoices',     COUNT(*) FROM invoices
+  UNION ALL SELECT 'app_settings', COUNT(*) FROM app_settings;"
+```
+
+Then open the admin login and use your **original** pre-disaster credentials.
+
+## Backup History detail
+
+Each row in **Backup → Backup History** expands to show:
+
+- **Database** — whether the dump was included
+- **Per-path file counts** — one row per `backup_paths` entry that contributed files, with count + total size. e.g.:
+  ```
+  events/active      142 (3.2 GB)
+  business-docs       17 (4.5 MB)
+  thumbnails         142 (12.4 MB)
+  ```
+- **Total files** + total bytes
+- Error message if the run failed
+
+This breakdown reflects Stage B's data-driven walker, so admins can see at a glance which paths contributed how much.
+
+## Settings reference
+
+Backup-related settings live in `app_settings` with `setting_type = 'backup'` or `setting_type = 'restore'`:
+
+| Setting | Default | Notes |
+| --- | --- | --- |
+| `backup_enabled` | true | Master scheduler switch |
+| `backup_destination_type` | `'local'` | `'local'`, `'s3'`, or `'rsync'` |
+| `backup_destination_path` | `'/backup'` | Local destination |
+| `backup_database_inline_dump` | true | Inline DB dump on every run |
+| `backup_include_archived` | false | Gate `events/archived` |
+| `backup_incremental` | true | Skip unchanged files (checksum-tracked) |
+| `restore_allow_force` | true | Permit Force Restore via the wizard |
+| `restore_require_pre_backup` | true | Take a pre-restore safety snapshot |
+| `restore_verify_checksums` | true | Verify file checksums after restore |
+| `restore_email_on_completion` | true | Notify admin when restore finishes |
+| `restore_retention_days` | 30 | How long pre-restore snapshots survive |
+
+Most settings are exposed in the **Backup → Configuration** tab. Less common ones can be set via SQL.
+
+## Troubleshooting
+
+### "Run Backup Now" fails with `No database backup available`
+
+The inline DB dump was disabled AND no recent scheduled dump exists. Either re-enable inline dumps (set `backup_database_inline_dump = 'true'`) or configure a scheduled DB dump that completes within the staleness window (default 26h).
+
+### Backup History row says "completed" but shows 0 files
+
+This is the legacy of a pre-2026-05 install where the walker was hard-coded and missed paths. After upgrading, the new walker captures everything per `backup_paths`. The 0-file row is historical — new backups will count correctly.
+
+### Restore wizard shows "No backups found"
+
+The wizard's disk discovery looks in `backup_destination_path` + its `manifests/` subdirectory. If you moved manifests elsewhere or your bind mount points at a different host directory than expected, the discovery won't find them. Check `backup_destination_path` in the Configuration tab matches reality.
+
+### Restore completes but login fails
+
+Caused by the pre-2026-05 dead-pool bug — fixed in the current image. If you're on a stale image and still see this, restart the backend container once:
+
+```sh
+docker compose restart backend
+```
+
+Then try logging in again.
+
+### Install-from-backup: boot log shows no `Install-from-backup:` lines
+
+Check that the trigger file is actually visible from inside the container:
+
+```sh
+docker compose exec backend ls -la /backup/RESTORE_ON_INSTALL
+docker compose exec backend cat /backup/RESTORE_ON_INSTALL
+```
+
+If `ls` reports the file but the hook didn't run, the most likely cause is that the trigger pointed at a manifest that doesn't exist. The hook silently returns when the manifest path can't be resolved. Verify the path inside the file matches an actual manifest:
+
+```sh
+docker compose exec backend ls -la /backup/manifests/
+```
+
+### Install-from-backup: restore fails and leaves the trigger file in place
+
+This is the intentional behavior — fix the input, then restart the container to retry. The boot log will surface the underlying error (e.g. corrupt manifest, missing database dump file, validator warnings without the force override).
+
+Common failure modes:
+
+- **Backup is files-only** (`database.backup_file = null` in the manifest). Pick a different backup or proceed with caution via the admin wizard, knowing you will restore files only.
+- **Manifest path mismatch.** The path in the trigger file points at a manifest that doesn't exist. Either fix the path or use the empty-file auto-pick variant.
+- **Existing data** without the force override. Either start from a truly empty install (`docker compose down -v`) or set `INSTALL_FROM_BACKUP_FORCE=true`.
+
+### How do I disable install-from-backup entirely?
+
+Don't create a `RESTORE_ON_INSTALL` file. Without the trigger, the hook is a no-op on every boot. There is no separate "off switch" because the feature is opt-in by design.

+# CRM disclaimers — important reading for every picpeak operator
+
+The CRM module ships defaults that touch two regulated areas: **legally
+binding contracts** and **payment instruments (QR-bills, IBAN/BIC)**.
+The text and data picpeak renders are mechanically correct, but the
+**substance is the operator's responsibility**.
+
+> [!IMPORTANT]
+> Whatever picpeak ships in these two areas is an **EXAMPLE ONLY**. It is
+> every operator's own duty to have the content reviewed by their lawyer
+> (for contracts) and verified with their bank (for QR-bills / SEPA EPC
+> payloads) before sending it to a customer. Picpeak does not provide
+> legal advice and cannot validate banking data — only the operator can.
+
+## 1. Contract block library
+
+The contract feature (`feat/crm`, migration `130_add_contracts.js`) seeds
+twelve "system" blocks across six sections:
+
+- Basics — contract subject / scope-of-work header
+- Scope — image-rights clauses (private + commercial variants)
+- Privacy — model-release clauses (private / commercial / minors), DSGVO notice
+- Commercial — payment-terms reference, tiered cancellation schedule
+- NDA — mutual confidentiality
+- Closing — jurisdiction (CH + DE variants)
+
+All bodies are hand-written by the picpeak maintainer (DE first, EN
+translated). **None of them have been reviewed by a lawyer.** They are
+intended as starting points — every operator must:
+
+1. Read each system block they intend to send.
+2. Adjust the body text to match their own jurisdiction, business
+   structure, and risk profile, in consultation with their lawyer.
+3. Where appropriate, replace a system block entirely with admin-authored
+   blocks under their lawyer's guidance.
+
+The admin UI surfaces this disclaimer:
+- as a persistent banner on the Block Library page,
+- as a persistent banner on the Contract Editor,
+- as a "system block" badge plus an "Examples only — have your lawyer
+  review" line on every seeded block's description.
+
+System blocks **cannot be deleted** (the seed migration would re-create
+them on re-run); operators who reject a seeded block toggle
+`is_active=false` on it so it stops appearing in new contracts. The body
+text of a system block is fully editable — when an operator's lawyer
+delivers a reviewed version, the operator pastes it into the system
+block and the new body is what gets snapshotted onto every subsequent
+contract.
+
+## 2. QR-bill / SEPA EPC payment payloads
+
+Picpeak is an open-source project. The invoice feature renders Swiss
+QR-bills and SEPA EPC QR codes from the data you typed (IBAN, BIC,
+account holder, amount, reference) — that's it. We don't have a way to
+tell whether the code actually scans correctly in your bank's app, so
+**please test that yourself before sending real invoices**.
+
+Before going live:
+
+1. Print one test invoice with the QR code.
+2. Scan it with the e-banking app of your own bank.
+3. If you expect customers on other banks (UBS, PostFinance, Raiffeisen,
+   Migros Bank for Swiss QR; any major SEPA bank for EPC QR), scan with
+   those too.
+4. If it doesn't scan or the prefilled fields look wrong, fix your
+   bank-account data in picpeak and try again.
+
+**We are not responsible for any mistakes** in the rendered QR codes,
+payment data, or anything that flows from sending an invoice with bad
+data on it. That's why picpeak is MIT-licensed — use it freely, but
+the verification is on you.
+
+The admin UI surfaces this same note as a banner on the Business
+Profile → Bank Accounts and QR-format settings pages.
+
+## 3. Signature type — picpeak provides SES, not QES
+
+The contract signing flow (typed name + acceptance checkbox + canvas
+signature image + IP address + timestamp + SHA-256 audit page) is a
+**Simple Electronic Signature (SES)** under the EU eIDAS regulation
+and the Swiss ZertES. SES is the same legal tier as DocuSign's basic
+plan, HelloSign's free tier, or Adobe Acrobat Sign without a
+qualified-certificate add-on.
+
+### What SES is legally sufficient for
+
+In DACH (CH, DE, AT, FL), SES is valid and routinely upheld in civil
+court for contracts that **don't** legally require a specific form:
+
+- Photography service agreements
+- Image-rights / model-release clauses
+- Cancellation policies
+- NDAs between private parties
+- Most commercial service contracts
+- Most B2B agreements
+
+For these, picpeak's evidence chain (frozen block bodies + signature
+images + names + IPs + timestamps + content hashes + immutable
+audit-log timeline) is comparable to what an SES provider charging
+€10–30/month delivers. The audit page appended to the signed PDF
+makes the evidence self-contained — the customer can re-hash their
+copy and prove integrity without trusting picpeak's database.
+
+### What SES is NOT sufficient for
+
+Certain documents **legally require Schriftform** (handwritten
+signature on paper) OR a **Qualified Electronic Signature (QES)**
+backed by a certificate from an accredited Trust Service Provider
+(Swisscom Sign, D-Trust, A-Trust, Bundesdruckerei, etc.). The most
+common categories in DACH:
+
+| Jurisdiction | Document type | Statute |
+|---|---|---|
+| DE | Bürgschaft (guaranty) | § 766 BGB |
+| DE | Verbraucherdarlehensvertrag (consumer loan) | § 492 BGB |
+| DE | Befristete Arbeitsverträge (fixed-term employment) | § 14 Abs. 4 TzBfG |
+| DE | Kündigung Arbeitsverhältnis (employment termination) | § 623 BGB |
+| DE | Aufhebungsvertrag (employment cancellation agreement) | § 623 BGB |
+| CH | Bürgschaft above CHF 2'000 | Art. 493 OR |
+| CH | Eheverträge (matrimonial property agreements) | Art. 184 ZGB |
+| AT | Bürgschaftserklärung (guaranty declaration) | § 1346 ABGB |
+
+If you send any of these via picpeak's signing flow, the signature
+is **legally invalid** and the contract may be unenforceable. Use a
+QES provider for these documents.
+
+If you're unsure which category your contract falls into, ask your
+lawyer. The cost of asking is hours; the cost of getting it wrong
+is years.
+
+### What picpeak does NOT provide
+
+- **Identity verification.** Anyone who receives the signing email
+  can sign. There's no second factor (SMS, video ident, ID upload).
+- **Qualified-certificate-based signatures (QES).** Requires a
+  separate service.
+- **External / third-party timestamp.** All timestamps are
+  server-side; an RFC 3161 Trust Service Provider timestamp would
+  close the clock-manipulation defence but isn't currently part of
+  the audit page.
+- **WORM / immutable storage.** Signed PDFs live on the regular
+  filesystem path under `storage/business-docs/contract/<year>/`.
+  Hardening this for high-stakes contracts is an infrastructure-
+  level decision (S3 Object Lock, etc.) outside picpeak's code.
+
+The signing flow is fine for routine photographer-customer
+contracts. For anything with significant economic value or
+Schriftform-bound documents, layer a QES provider on top of
+picpeak's contract management.
+
+## Why this matters
+
+- **Liability.** Sending an unreviewed contract or a malformed QR-bill
+  is the operator's liability — not picpeak's. The MIT licence
+  explicitly disclaims warranty.
+- **Jurisdictional variance.** Even the most carefully drafted clause
+  is wrong somewhere. The CH-jurisdiction closing block won't help a
+  photographer in Bavaria. The cancellation schedule that's standard
+  in Zurich would be challenged in Berlin.
+
+If you are unsure: don't send. Pause, read this file again, and run
+your seeded contract content past your lawyer (or scan one test QR-bill
+yourself) before turning the feature on for live customers.

+# Live Slideshow ("Diashow")
+
+The Live Slideshow is a dedicated, token-only, **fullscreen** URL for an event that **auto-picks-up newly uploaded photos while it runs** — designed for a projector or screen at a live event (weddings, concerts, parties). Guests at the venue watch the photos appear in near real time; the photographer keeps culling and uploading from the back of the room.
+
+It is separate from the normal guest gallery: its own link, no gallery password, no chrome — just the photos.
+
+## Table of contents
+
+- [Enable the feature](#enable-the-feature)
+- [Create a slideshow link](#create-a-slideshow-link)
+- [Run it on a projector](#run-it-on-a-projector)
+- [Global defaults (Settings → Slideshow)](#global-defaults-settings--slideshow)
+- [Per-event options](#per-event-options)
+- [How live updates work](#how-live-updates-work)
+- [Good to know](#good-to-know)
+
+## Enable the feature
+
+Live Slideshow is **off by default**. Turn it on under **Settings → Features → Live Slideshow**. While it's off, no slideshow UI appears and any existing slideshow link returns "not active".
+
+## Create a slideshow link
+
+1. Open the event, find the **Live Slideshow** card.
+2. Click **Generate slideshow link**. This mints a unique link of the form:
+
+   ```
+   https://your-host/gallery/<event-slug>/show/<token>
+   ```
+
+3. **Copy** it (or **Regenerate** to rotate the token and kill the old link, or **Disable** to remove it). The link is a secret — the token *is* the access; there is no separate password.
+
+The link only shows **published, non-hidden** photos — the same set guests see.
+
+## Run it on a projector
+
+Open the link on the machine driving the projector. You'll see a **▶ Start slideshow** splash. Click it once — browsers only allow fullscreen in response to a click — and it goes fullscreen and starts cycling. From then on it runs unattended: cursor hides, it loops at the end, and shows a "Waiting for photos…" screen if the event has none yet.
+
+## Global defaults (Settings → Slideshow)
+
+The picpeak-wide look and feel lives in one place: **Settings → Slideshow**. These apply to every slideshow.
+
+- **Default style for new slideshows** — the transition, display time, transition speed and color filter that **new events inherit**. Each event can still override these.
+  - Transitions: **Crossfade, Cut, Slide, Ken Burns, Dip to white, Dip to black**.
+  - Color filters: None, Black & White, Sepia, Warm, Cool, Vignette.
+- **Image fit** — **Fill screen (crop)** or **Black bars (no crop)**. Use black bars if your set is portrait-heavy and you don't want faces cropped. *(Live — applies to running slideshows immediately.)*
+- **Watermark** — overlay a logo in a corner, TV-station-ident style.
+  - **Logo**: your light logo, dark-mode logo, favicon, or the event's own logo (shown with a live preview).
+  - **Style**: **White** (recolors a dark/transparent logo white) or **Original colours** (for a logo that already has its own colours/box).
+  - **Position**, **opacity**, and **size**.
+  *(Live — applies immediately.)*
+
+## Per-event options
+
+On the event's Live Slideshow card you can:
+
+- Generate / copy / regenerate / disable the link.
+- Override the **display style** (transition, timing, color filter) for this event.
+- Override the **watermark**: **Use global default**, **On**, or **Off** — e.g. turn the watermark off for one sensitive event without changing your global setting.
+
+## How live updates work
+
+While a slideshow is running it polls a lightweight endpoint every few seconds:
+
+- **New uploads are appended quietly** at the end — the current slide is never interrupted or skipped.
+- **Settings changes apply live** — change the display time, transition, image fit or watermark and the running projector picks it up within a few seconds. No need to regenerate the link or restart.
+- **Disabling the feature (or the link) kills it** — turning off the **Live Slideshow** feature flag, or disabling/regenerating the link, makes the projector stop on its next poll.
+
+## Good to know
+
+- **The token is the secret.** Anyone with the link can view the slideshow — **published photos only**: a slideshow link is display-only and cannot download, upload, or post feedback. Rotate it with **Regenerate** if it leaks; **Disable** removes it entirely.
+- **Regenerate / Disable is not instant revocation.** A running projector stops within one poll, but the browser session it already opened keeps working for **up to 12 hours** on the old token (there's no token-revocation list — same as gallery passwords). For a hard cut-off, also turn the **Live Slideshow** feature flag off, which denies every link immediately.
+- **Fullscreen needs the first click.** The ▶ splash exists because browsers require a user gesture to enter fullscreen — unavoidable, and harmless for a projector.
+- **Slideshow views don't pollute analytics.** The projector is excluded from your event's visitor view/download counts.
+- **Turning the feature off suspends, doesn't destroy.** Existing links stop working while the flag is off and resume when you turn it back on — the token isn't deleted.

+# Migration: PicPeak moved to its own GitHub organization
+
+PicPeak's repository moved from the maintainer's personal handle to a dedicated
+GitHub organization. This is a one-time, operator-facing change. The software
+itself is unchanged; only the URLs you pull images from have moved.
+
+## TL;DR — what changed and what you need to do
+
+| | Before | After |
+|---|---|---|
+| **Repository URL** | `github.com/the-luap/picpeak` | `github.com/PicPeak/picpeak` |
+| **Docker images** | `ghcr.io/the-luap/picpeak/{backend,frontend}` | `ghcr.io/picpeak/picpeak/{backend,frontend}` |
+| **Branches (active dev)** | `beta` | `main` |
+| **Branches (stable channel)** | `main` | `stable` |
+
+**Action required**: update your `docker-compose.yml` to pull from
+`ghcr.io/picpeak/picpeak/{backend,frontend}`. The old path no longer serves
+images.
+
+## Why this changed
+
+The repo lived under a personal GitHub handle since the project began. Moving to
+an organization is a one-time housekeeping step that:
+
+- Separates the project's identity from any individual maintainer's account.
+- Lets the project add additional maintainers later without re-transferring.
+- Matches the convention every other open-source project uses for branch names
+  (`main` = active development, `stable` = curated production channel).
+
+## docker-compose.yml — exact edit
+
+Find these two lines:
+
+```yaml
+    image: ghcr.io/the-luap/picpeak/backend:${PICPEAK_CHANNEL:-stable}
+    # ...
+    image: ghcr.io/the-luap/picpeak/frontend:${PICPEAK_CHANNEL:-stable}
+```
+
+Replace with:
+
+```yaml
+    image: ghcr.io/picpeak/picpeak/backend:${PICPEAK_CHANNEL:-stable}
+    # ...
+    image: ghcr.io/picpeak/picpeak/frontend:${PICPEAK_CHANNEL:-stable}
+```
+
+Then:
+
+```bash
+docker compose pull
+docker compose up -d
+```
+
+That's it. No data migration, no config changes, no database changes.
+
+## What auto-redirects (you don't have to change)
+
+GitHub redirects the old repo URL indefinitely, so these all keep working:
+
+- Browser links to `github.com/the-luap/picpeak/...` (issues, PRs, files)
+- `git clone https://github.com/the-luap/picpeak.git`
+- GitHub API calls to `api.github.com/repos/the-luap/picpeak/...`
+
+Worth updating to the canonical `PicPeak/picpeak` form when convenient, but
+nothing breaks if you don't.
+
+## What does NOT auto-redirect
+
+- **GHCR image paths.** `ghcr.io/the-luap/picpeak/*` returns **404** — you must
+  update your compose file.
+
+## Branch rename
+
+The active-development branch was renamed from `beta` → `main`, and the previous
+`main` (stable channel) was renamed to `stable`. This matches the convention
+every other open-source project uses.
+
+If you're a contributor:
+
+- **Feature PRs**: target `main`.
+- **Bugfix PRs**: target `main`. If the fix also needs to ship to current stable
+  users, open a separate small PR against `stable`.
+
+If you're an operator: ignore. Branch names don't affect pulls.
+
+## Got stuck?
+
+Open an issue at https://github.com/PicPeak/picpeak/issues with the error
+message and we'll help.

+ *
+ * Placed in /public so vite copies it to /bootstrap.js at build time

+ * BackupIntegrityCard — on-demand verifier for CRM document artefacts.
+ *
+ * Walks every `*_path` column on quotes / contracts / invoices and
+ * confirms (a) the referenced file exists on disk, (b) where a SHA-256
+ * is stored, the file's bytes hash to the expected value. Surfaces
+ * three failure buckets:
+ *
+ *   - missing         — `*_path` set, file not on disk (broken FK)
+ *   - hashMismatches  — file exists but bytes don't match the stored hash
+ *   - existsButNoHash — verified by existence only; weaker evidence
+ *
+ * Designed to be portable. Currently embedded as a tab on
+ * `BackupManagement.tsx`; when the System Health page (backlog item)
+ * lands, this same component can be lifted there without changes.

+/**
+ * CustomerPicker — shared search-or-create surface for the three CRM
+ * editors (Quote, Bill, Contract).
+ *
+ * **Why this exists**
+ *
+ * The audit flagged that QuoteEditorPage, BillEditorPage, and
+ * ContractEditorPage each carried near-identical ~80-line customer
+ * picker blocks: a "currently selected" row when an id is present,
+ * a search-debounced lookup with passive-badge chips, and an
+ * "InlineCustomerCreate" expansion when the admin clicks "+ Create
+ * new customer". The three copies had drifted: passive badge text
+ * positioning differed, the contract variant used a bare `<input>`
+ * instead of the shared `<Input>` component, and the contract change
+ * link used `text-accent-dark hover:underline` instead of the
+ * Button-variant "outline" style the other two used.
+ *
+ * Behavior unified here matches the Quote and Bill variants (which
+ * were already in sync with each other); the contract variant's
+ * styling differences are folded in.
+ *
+ * **API**
+ *
+ *   <CustomerPicker
+ *     value={customerAccountId}        // number | null
+ *     label={customerLabel}            // pre-formatted display label
+ *     isPassive={customerIsPassive}    // boolean
+ *     onSelect={(c) => { ... }}        // CustomerSummary from search
+ *     onCreate={(c) => { ... }}        // CustomerAccountDetail from inline create
+ *     onClear={() => { ... }}          // user clicked "Change"
+ *     readOnly={false}                 // contract editor uses true on edit
+ *   />
+ *
+ * The component owns the `customerSearch` state + the debounced
+ * useQuery against customerAdminService.search and the "+ Create new
+ * customer" expansion toggle. Parents own the canonical
+ * `customerAccountId / label / isPassive` triple because each editor
+ * stores them differently (Quote nests them inside a form object,
+ * Bill + Contract use separate useStates). Keeping the triple owned
+ * by the parent avoids a forced shape migration.
+ *
+ * **Selection vs creation callbacks**
+ *
+ * `onSelect` receives the CustomerSummary shape from the search
+ * endpoint (id, email, displayName, companyName, firstName, lastName,
+ * isPassive). `onCreate` receives the full CustomerAccountDetail
+ * because some editors want to inherit additional fields from a
+ * freshly-created customer (e.g. Quote inherits the new customer's
+ * preferredLanguage so the doc renders in their locale by default).

+ * <DocumentLineageCard> — flat list of every document sharing one
+ * `deal_uuid` (migration 140), grouped by type. Renders on the three
+ * detail pages (Quote / Contract / Bill) so the admin sees the
+ * complete chain — quotes + contracts + invoices (incl. Storno /
+ * reissue / installment siblings) — without walking individual FKs.
+ *
+ * Data comes from `GET /api/admin/deals/:uuid/documents` (commit #3).
+ * The card is purely presentational; the parent passes the dealUuid
+ * and a `currentId` so the row representing "the document you're
+ * looking at" can be highlighted instead of linked.
+ *
+ * When no other documents share the deal (newly-created standalone
+ * doc), the card renders a compact "no related documents" line
+ * instead of three empty groups — keeps the detail page from looking
+ * busy on the common case.

+ * (via the lineage payload — no extra fetch needed).
+ *
+ * Triggered from `<DocumentLineageCard>`, which only renders the

+ * scheduled / pending_delivery (the same gate enforced server-side).
+ * The server still re-checks on save; a 409 INVOICE_LOCKED races back
+ * if a sibling shipped between modal open and save click.
+ *
+ * Plan total preservation: the backend uses sum(existing sibling totals)

+/**
+ * <EventReminderOverrideCard>
+ *
+ * Per-event override for the pre-event customer reminder (migration
+ * 143). Mounted once on the EventDetailsPage; admin can:
+ *   - Disable the reminder for THIS event only (no global flip)
+ *   - Override the global "days before" offset (null = inherit)
+ *   - Provide a custom body that overrides the resolved template's
+ *     body for THIS event only (subject still comes from the template)
+ *
+ * Saves through the existing PUT /api/admin/events/:id endpoint with
+ * the three new whitelisted fields (added 2026-05-25):
+ *   - event_reminder_disabled        (bool)
+ *   - event_reminder_offset_days     (int | null)
+ *   - event_reminder_body_override   (string | null)
+ *
+ * Behaves correctly on pre-migration installs: if the event object
+ * doesn't carry the new fields, the form starts blank and "Reset to
+ * default" is a no-op until admin saves something.
+ *
+ * Strings: every label / hint / button goes through `t()` with a
+ * fallback. The maintainer flagged "no hard coded i18n" in commit #5
+ * — applying that convention strictly from here forward.

+ *
+ * Two save modes:
+ *   - "Save as passive customer" → POST /admin/customers. No email,
+ *     no invitation. The customer becomes a usable record
+ *     immediately for the current quote/invoice.
+ *   - "Save & send portal invitation" → POST /admin/customers
+ *     followed by POST /admin/customers/:id/send-invite. Customer is
+ *     created (passive in DB), then a standard onboarding email is
+ *     queued so they can claim portal access. Orchestrated client-
+ *     side so the backend endpoints stay simple and single-purpose.
+ *
+ * If the second call fails after the first succeeds, the customer
+ * stays saved (passive) and a warning toast asks the admin to retry
+ * from the customer detail page.
+ *
+ * Field set mirrors the customer detail page so admins see the same
+ * shape regardless of where they're editing.

+/**
+ * <InstallmentsPanel> — shared editor surface for the per-document
+ * installment plan. Used by both QuoteEditorPage and BillEditorPage.
+ *
+ * Two render modes:
+ *   - Simple (default): per-row date picker mapped to trigger='fixed_date'
+ *   - Advanced (toggle): per-row trigger dropdown + offset_days
+ *
+ * Rows store the canonical {label, percent, trigger, offset_days}
+ * shape (PaymentTermInstallment from quotes.service.ts). Date pickers
+ * are a UX convenience layered over `trigger='fixed_date' + offset_days`.
+ *
+ * When the panel is "off" (`value: null`), the document is treated as
+ * a single-invoice / single-payment plan and the parent editor skips
+ * the installment field on save. Switching the panel on inserts a
+ * default 100% row pre-populated from `useInstallmentDefaults()`.
+ *
+ * Validation: percents must sum to 100 (rendered inline below the
+ * footer; parent uses `onValidityChange` to disable Save when wrong).
+ *
+ * The parent owns the `value` state; this component is fully
+ * controlled. Render is React-Strict-Mode safe (no state in refs that
+ * outlives the props).

+/**
+ * Reusable line-items editor for quotes + invoices.
+ *
+ * Two-level hierarchy (migration 119):
+ *   - Top-level items roll into the document net/VAT/total.
+ *   - Sub-items render indented under their parent. Their line total
+ *     is shown in parentheses for transparency but is display-only;
+ *     only the parent's price contributes to net.
+ *   - Per-item `detailsText` is an optional free-form notes block
+ *     rendered below the description on the PDF + customer view.
+ *
+ * Items in `items` are kept in DISPLAY ORDER (parent immediately
+ * followed by its sub-items, then the next parent, etc.). `position`
+ * is a stable unique identifier used to link sub-items to parents in
+ * the payload — once assigned at row creation we never renumber it.
+ * Move up/down only swaps within the same level (top-level among
+ * top-level, sub-items among siblings of the same parent).
+ *
+ * Money values are stored in MAJOR units in the form state (e.g. 250.00)
+ * for editor ergonomics, then converted to minor (25000) when persisting.
+ * The conversion happens at the save boundary in the parent page.

+ * Promise-based confirm dialog (#640 part C, ported from 8digit/picpeak@88bfde1).
+ *
+ * Replaces `window.confirm()` with a styled, themed, accessible in-app modal.
+ * Usage:
+ *
+ *   const confirm = useConfirm();
+ *   const ok = await confirm({
+ *     title: 'Delete event?',
+ *     message: 'This will permanently remove the gallery and all photos.',
+ *     variant: 'danger',
+ *     confirmLabel: 'Delete',
+ *   });
+ *   if (ok) doDelete();
+ *
+ * Wraps once at the App level via <ConfirmDialogProvider />; every component
+ * below it gets `useConfirm()` for free. Variants:
+ *   - 'primary' (default) — plain confirm, no icon
+ *   - 'danger'            — red AlertCircle, red confirm button
+ *   - 'warning'           — amber AlertTriangle
+ *
+ * Keyboard: Escape cancels, Enter confirms, backdrop click cancels. The cancel
+ * button is focused by default so a stray Enter doesn't accidentally confirm a
+ * destructive action.
+ *
+ * This is the generic primitive. Existing inline-modal flows (PublishGalleryDialog,
+ * DuplicateEventDialog, PasswordResetModal, etc.) stay as-is — they collect
+ * structured input, not a simple yes/no. Call-site sweeps of `window.confirm()`
+ * follow in later PRs.

+/**
+ * /admin/clients/calendar — admin calendar (read-only skeleton for E.6).
+ *
+ * Renders four layers fetched in one shot from /api/admin/calendar/items
+ * (backend route adminCalendar.js, E.3):
+ *
+ *   - events (galleries)              → blue solid
+ *   - hour entries                    → green solid (greyed when locked)
+ *   - pending quotes (not converted)  → amber dashed
+ *   - pending contracts (not converted) → purple dashed
+ *
+ * View toggle (Month / Week) persists per admin via localStorage
+ * (`utils/calendarPrefs.ts`).
+ *
+ * Click behaviour:
+ *   - event    → /admin/events/:slug
+ *   - quote    → /admin/clients/quotes/:id
+ *   - contract → /admin/clients/contracts/:id
+ *   - hours    → noop in E.6; E.7 adds the inline edit popover.
+ *
+ * Interactions deferred to E.7:
+ *   - drag-create on empty slots (hour-entry create modal)
+ *   - drag-resize / drag-move on unlocked hour entries
+ *   - inline edit popover on hour entries
+ *
+ * Bundle note: this file is the entry point of the `fullcalendar` chunk
+ * carved in vite.config.ts (E.5). FullCalendar's plugin imports flow
+ * through here only — the calling App.tsx loads this module lazily.

+/**
+ * HourEntryDragCreateModal — opens when the admin drag-selects an
+ * empty time range on the admin calendar (E.7).
+ *
+ * Pre-filled fields from the drag:
+ *   - entryDate  (the drag's start day, YYYY-MM-DD)
+ *   - startTime  (HH:MM)
+ *   - endTime    (HH:MM)
+ *
+ * Admin picks the customer through the existing CustomerPicker (C.5)
+ * and optionally adds a description. Submit → POST /admin/customers/
+ * :id/hour-entries (existing route from migration 129 + B.6 permission
+ * split). On success, the calendar invalidates its `calendar-items`
+ * query so the new entry appears as a green block.
+ *
+ * Per user spec: customer field is BLANK by default — no pre-fill from
+ * the day's events even when there's exactly one event on that day.
+ * Admin picks every time.
+ *
+ * The drag-create UX is gated by the existing route-layer permission:
+ * the parent page already requires `customers.view`; the backend
+ * enforces `customers.edit` on the POST. If the admin's role is
+ * view-only, the modal opens but the submit fails with a clean 403
+ * from the backend and the toast surfaces the error.

+ * HourEntryInlinePopover — quick-edit / delete for an hour entry,

+ * Two render modes:
+ *   - editable (item.locked === false): start/end/description fields
+ *     + Save + Delete buttons. Save → PUT /admin/customers/:id/
+ *     hour-entries/:entryId. Delete → DELETE same.
+ *   - locked   (item.locked === true): read-only summary + a lock
+ *     badge + tooltip "Billed — invoice X locked. Storno to edit."
+ *
+ * Lock predicate is computed by the backend (customerHoursService.
+ * _internal.isEntryLocked) and surfaced on each item via E.3. The
+ * popover trusts that flag for the UI gate; the backend STILL enforces
+ * the rule on every mutation (PUT/DELETE return 409 ENTRY_LOCKED when
+ * the row's invoice has shipped), so even if a stale flag slipped
+ * through, the user-visible state stays correct.
+ *
+ * Why a portal-style fixed overlay rather than a positioned bubble:
+ * FullCalendar doesn't ship a popover anchor, and the admin calendar
+ * already uses a similar full-screen overlay for the drag-create
+ * modal. Reusing the pattern keeps the visual language consistent.

+/**
+ * Admin → Contract block library.
+ *
+ * Two-column layout intentionally mirroring EmailConfigPage's Templates
+ * tab so admins navigate one shape across all template-style editors:
+ *   - Left: sticky sidebar with sections (basics / scope / privacy /
+ *     commercial / nda / closing) as uppercase headings, blocks listed
+ *     below each, "+ New block" button at the top. Selected block
+ *     uses `tile-selected`; non-selected blocks use the same
+ *     `bg-neutral-50 dark:bg-neutral-700` palette as the email tabs.
+ *     Inactive blocks render `opacity-50`.
+ *   - Right: edit panel with language tabs (EN/DE/RU/PT/NL/FR) at the
+ *     top, then Section + Name + Description + Body fields. Active
+ *     toggle + Save + Delete actions. New-block mode renders the same
+ *     form with empty values and an enabled Section dropdown.
+ *
+ * Schema: contract_blocks carries body_text + body_text_<locale> for
+ * each of the six locales (migration 130 seeded EN+DE; migration 131
+ * added RU/PT/NL/FR as nullable). Translation completeness shown in
+ * the sidebar pill (e.g. "3/6") matches the email-templates display.

+ * Admin → Contracts list page.

+ * Lists every contract (filterable by status + customer + search) with
+ * a "New contract" button and a "Block library" shortcut. Visual
+ * shape mirrors BillsListPage / QuotesListPage so the three lists
+ * under /admin/clients feel like one product — same container wrapper,
+ * same h1 + BETA badge, same Button component for actions, same table
+ * head + row-hover + click-row-to-open behaviour. Contract-specific
+ * columns (Number, Customer, Title, Issued, Status) and the per-status
+ * badge palette are preserved.

+/**
+ * Admin → Settings → CRM → Reminder Emails.
+ *
+ * Two-column layout deliberately mirroring the contract block library
+ * and the email-template editor so admins navigate one shape across
+ * every template surface. Left rail lists "Default (catch-all)" first,
+ * then every active event_type from the catalog with a "Default" pill
+ * when no per-type template exists yet (admin's first save creates it
+ * from whatever's currently in the form, which on entry mirrors the
+ * default).
+ *
+ * Right panel: full language tab row (EN/DE/RU/PT/NL/FR with flags +
+ * amber bullets for missing translations) → Subject input → the same
+ * tiptap-based `EmailTemplateEditor` used in the main email-templates
+ * editor so the body styling, toolbar, and variable inserter match.
+ *
+ * Plus a header strip with the two global toggles (`crm_event_reminders_enabled`,
+ * `crm_event_reminders_days_before`).
+ *
+ * Template-key naming convention (matches eventReminderService):
+ *   - `event_reminder_default` — catch-all, seeded at runtime
+ *   - `event_reminder_<event_type slug_prefix>` — per-type override
+ *
+ * Per-type templates that don't exist yet have their right-panel fields
+ * pre-filled from the default's content so admin can see what the
+ * customer would currently receive and decide whether to override.
+ * First Save on such a row hits POST /admin/email/templates which
+ * creates the per-type row.

-// Umami Analytics Service
-// Provides integration with Umami for tracking page views and events

+//
+// Routes initialization to the right tracker based on the operator's chosen
+// provider in Settings → Analytics, and dispatches `track()` calls to the
+// tracker's runtime API when one is loaded.
+//
+//   None    → no script, no-op tracking.
+//   Umami   → inject Umami script tag; `window.umami.track(name, data)`.
+//   Rybbit  → inject Rybbit script tag; `window.rybbit.event(name, data)`.
+//   Custom  → render admin-pasted HTML (sanitised server-side) into <head>;
+//             no runtime API hook — `track()` becomes a no-op.

+ *     language), not de-CH. Call-sites can override with the `locale`
+ *     option for special cases (e.g. always-DE PDF previews).
+ *   - Two entry points: `formatMoney` for MAJOR units (preferred —
+ *     matches what most templates and editor forms already pass), and
+ *     `formatMoneyMinor` for MINOR units (use this when reading raw
+ *     `*_amount_minor` columns).
