+# 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
 
-Releases are cut from the `beta` branch (rolling beta) and promoted to `main` (stable) on a 4–6 week cadence. `release-please` handles version bumps, changelog generation, and Docker image publication automatically — contributors don't update `package.json` or `CHANGELOG.md` by hand.

-See [RELEASING.md](RELEASING.md) for the full operational doc (promotion criteria, conflict-resolution checklist for the beta→main merge, hotfix backport path, versioning rules).
+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).

 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).

 ## TL;DR
 
-- **`beta` branch** receives all merged work. Every push triggers a `release-please` PR that proposes the next `vX.Y.Z-beta.N` release. Merging that PR tags the beta and publishes Docker images on the `beta` tag.
-- **`main` branch** holds the stable channel. Stable releases are cut from a known-good `beta` point via a `release/X.Y.Z-merge-from-beta` branch and a manual PR to `main`. Merging that PR triggers `release-please` to propose the stable release.
-- Target cadence: **a stable release every 4–6 weeks**, or sooner if a beta has been quiet and ready for promotion.
+- **`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 beta 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 beta releases (multiple beta 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 a beta has been quiet and stable longer than usual. Cut later if a beta is in flux for security or migration reasons.

 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 beta before re-evaluating.

 ## How a stable release is cut
 
 The actual mechanics, in order:
 
-1. **Pick the beta tip.** Confirm it satisfies the four promotion criteria above. Note the exact SHA — that's what you're promoting.
+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 beta tip.**
+2. **Create the release branch from the `main` tip.**
    ```bash
-   git push origin <beta-tip-sha>:refs/heads/release/X.Y.Z-merge-from-beta
+   git push origin <main-tip-sha>:refs/heads/release/X.Y.Z-merge-from-main
    ```
-   Naming convention: `release/X.Y.Z-merge-from-beta`, 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 `main`.** Title: `chore(release): promote beta → main 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.
+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.** Main almost always has commits beta 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 beta's version (superset), but verify any security-pinned deps (`axios`, `nodemailer`, `i18next-http-backend`, `multer`, `tar`) on beta are `>=` the pinned versions on main. If main has a newer pinned version (e.g. an emergency CVE backport beta hasn't picked up), take main's pin.
-   - **`README.md`** — keep main's version if main has had a recent rewrite that beta didn't pick up; otherwise take beta's.
-   - **`CHANGELOG.md`** — keep main's; release-please regenerates entries on its next stable cut from the commits going forward.
-   - **`.release-please-manifest.json`** — keep main's; release-please owns this file.
+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:

+   - **`.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 beta — beta has already moved on).
