+name: Schema drift (#530)
+
+# Verifies that `migrate:safe` can recover a DB that's been seeded only
+# by `initializeDatabase()` — the recovery scenario where the migrations
+# tracking table is empty but the schema already has the modern bootstrap.
+#
+# This is NOT how production reaches its state on normal installs or
+# upgrades. The scenario only fires when:
+#   - A backup was restored that captured tables but not the migrations
+#     table (manifest divergence),
+#   - Someone manually invoked initializeDatabase() outside the migration
+#     runner (recovery / debugging),
+#   - The DB was moved between systems and the migrations table was not
+#     copied along.
+#
+# When `detectExistingSchema()` sees the modern-bootstrap fingerprint
+# (photo_categories + cms_pages tables) but an empty migrations table,
+# it treats it as an "existing deployment" — which runs the legacy
+# chain first. Legacy/008 renames email_templates.subject → subject_en,
+# but core/029 (which runs later in this chain) inserts email templates
+# referencing the pre-rename column name. The chain dies with a
+# "column subject does not exist" error.
+#
+# Fix (in the same PR as this workflow): when the modern-bootstrap
+# fingerprint is detected, mark all legacy migrations as applied so the
+# chain matches what a fresh install runs — only core/*, in order.
+#
+# This workflow boots the failing scenario from scratch on every PR
+# that touches the migrations or db.js, so any future migration with
+# the same shape is caught before merge.

+# 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.

+## 🌿 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).

 Get PicPeak running in under 5 minutes:

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

-# Copy environment template
+# Copy the environment template — the defaults work out of the box.
+# Machine secrets (JWT, DB, Redis) are auto-generated on first run, and the
+# admin account is created in the browser (see below). Edit .env only to
+# customise (domain, SMTP, storage paths, …) — nothing is required.
 cp .env.example .env

-# Edit configuration (required: JWT_SECRET)
-nano .env
-
 # Start with Docker Compose
 docker compose up -d

 # Access at http://localhost:3000
 ```

-Note on Docker file permissions (PUID/PGID)
- When using bind mounts (e.g., `./storage`, `./data`, `./logs`, `./events`), ensure the container user can write to these host folders. The backend runs as a non‑root user by default.
- Set `PUID` and `PGID` in your `.env` to match your host user’s UID/GID (run `id -u` and `id -g` on the host). Compose maps the container user to these values.
- Example in `.env`:
-  - `PUID=1000`
-  - `PGID=1000`
- Without this, creating events, uploads, thumbnails, or logs can fail with "Permission denied".
+### 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).

 **ARM64 (aarch64) systems:** Pre-built images include native `linux/arm64`, no platform flags or emulation needed. If you're on an older image tag that's still amd64-only, see [docker-compose.amd64.override.yml](docker-compose.amd64.override.yml) for a transitional fallback.

+### 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.

+# 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.

+ * 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.

+ *   3. New row inserted at runtime → walker picks it up without restart

+ *   5. Empty table → walker falls back to LEGACY_BACKUP_PATHS (defense
+ *      in depth — never silently scans nothing)
+ *
+ * Why not stub `db('backup_paths')`: the whole point of Stage B is

+ * 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.
