Release Process (Strict SOP)

This document defines the only allowed release workflow for this repository. All maintainers should follow it exactly.

1) Branch roles

• main:
  • primary development branch
  • all regular feature/fix work lands here via PR
  • should usually carry a development version (for example X.Y.Z-dev)
• next:
  • release-candidate (RC) stabilization branch
  • receives promoted changes from main
  • receives RC-only fixes during freeze
• release:
  • stable release branch
  • only receives promoted commits from next

Direct push to these branches is not part of normal human workflow. Use PRs and promotion workflows.

2) Versioning rules (mandatory)

Version is authoritative in package.json and package-lock.json. Promotion workflows run scripts/sync-tauri-version-from-package.js, which also aligns [workspace.package] in src-tauri/Cargo.toml, tauri.conf.json, and the psysonic* workspace crate version fields in src-tauri/Cargo.lock (local cargo build alone does not commit that lock metadata).

• main version format: X.Y.Z-dev
• next version format: X.Y.Z-rc.N
• release version format: X.Y.Z

Rules:

1. Never edit versions manually in random commits.
2. Version transitions must happen through the defined promotion workflows.
3. Tags must match package version:
   • RC: app-vX.Y.Z-rc.N
   • Stable: app-vX.Y.Z

3) Standard release flow

Step A: Prepare in main

1. Merge ready PRs into main.
2. Confirm CI is green on main.
3. Refresh the bundled Open-Source-Licenses data (maintainer-only, run locally):
   • Requires cargo-about (one-time install: cargo install cargo-about --features cli).
   • Run directly: node scripts/generate-licenses.mjs from the repo root.
   • Inspect the diff on src/data/licenses.json (size + entry count delta should be plausible).
   • Commit on main if the file changed. No npm script wrapper exists on purpose — adding one to package.json would trigger the nix-npm-deps-hash-sync workflow on every push. Contributors consume the committed JSON as-is.

Step B: Promote to RC (next)

0. Confirm WHATS_NEW.md has a ## [X.Y.Z] section for the release line about to ship (user-facing copy for the in-app What's New screen; CI uploads it as whats-new.md on the release tag).
1. Run workflow: Promote main to next.
2. Workflow behavior:
   • validates required main checks before promotion (default: ci-ok, or UI-style ci-main / ci-ok; either satisfies the gate)
   • resets next to main snapshot
   • auto-bump package version in next to next -rc.N
   • commit and push version bump
3. Push on next triggers Next Channel workflow:
   • build/publish RC artifacts for all platforms
   • run Nix verification path

Step C: Stabilize RC

1. Test RC artifacts.
2. If fixes are needed, follow Section 5 (RC fix policy).
3. Repeat Step B as needed until release candidate is accepted.

Step D: Promote to stable (release)

1. Run workflow: Promote next to release.
2. Workflow behavior:
   • resets release to next snapshot
   • finalize version from -rc.N to X.Y.Z
   • commit and push finalized version
3. Push on release triggers Release Channel workflow:
   • stable artifact publish
   • Nix verification
   • opens PR to bump main to next minor -dev

Step E: Move main forward

1. Merge the auto-generated PR that bumps main to next minor dev version.
2. Confirm main now uses X.(Y+1).0-dev.
3. Update AUR package metadata for the same stable version:
   • bump pkgver in packages/aur/PKGBUILD
   • regenerate packages/aur/.SRCINFO
   • publish/update in AUR remote

4) Freeze policy (RC stabilization window)

When RC freeze starts:

• Do not run Promote main to next automatically or casually.
• Only approved release manager(s) may run promotion workflows.
• next accepts only stabilization changes (fixes/docs/chore required for release quality).
• New features remain in main and wait for next cycle.

Freeze ends after next -> release promotion is complete.

5) RC fix policy (strict backport/forward-port rules)

If a bug is discovered during RC stabilization:

1. Create dedicated fix branch from next:
   • example: fix/rc-crash-login
2. Open PR: fix/rc-crash-login -> next
3. After merge to next, create dedicated backport branch from main:
   • example: fix/backport-rc-crash-login-main
4. Cherry-pick (or re-apply) same fix.
5. Open PR: fix/backport-rc-crash-login-main -> main
6. Merge this main backport PR before the next Promote main to next run.

This is mandatory. RC-only fixes may not stay only in next.

Alternative allowed order:

• implement first in main, then promote main -> next.

But if main is ahead with non-release features and promotion is frozen, use the next-first + mandatory main backport flow above.

6) Post-release critical hotfix policy (default path)

After a stable release X.Y.Z, critical fixes must be shipped as a patch release:

• next stable target is always X.Y.(Z+1)
• RC tags for hotfix cycle: app-vX.Y.(Z+1)-rc.N
• final stable tag: app-vX.Y.(Z+1)

Never re-use or overwrite X.Y.Z tags/releases.

Case A: next is not yet used for the next minor

This case is uncommon in this repository but allowed.

1. Create hotfix branch from release.
2. Implement fix and open PR to release.
3. Move patch line through next RC flow (X.Y.(Z+1)-rc.N).
4. Promote next -> release for final X.Y.(Z+1).
5. Backport fix to main via dedicated PR (mandatory).

Case B (default): next already tracks next minor

This is the expected real-world case.

Assume:

• release is 1.9.0
• main/next already moved to 1.10.0-*
• critical bug requires 1.9.1

Required steps:

1. Announce hotfix override window and freeze normal next-minor RC flow.
2. Create hotfix branch from release (1.9.0 baseline).
3. Implement fix and merge into release branch via PR.
4. Temporarily align next to the hotfix patch line for RC publication.
5. Publish hotfix RC(s): 1.9.1-rc.N.
6. Promote next -> release to finalize 1.9.1.
7. Backport/cherry-pick same fix into main via dedicated PR (mandatory).
8. Restore next back to the normal next-minor line from main.
9. Announce end of hotfix override and resume normal RC cycle.

Hard rule: no feature work may be merged into next during hotfix override.

7) Idempotency and rerun behavior

Manual workflow reruns should be safe:

• rerunning Promote main to next:
  • no change if no new commits
  • version bump occurs only when needed for next RC number
• rerunning Promote next to release:
  • no change if release already matches next
  • no extra version increment beyond X.Y.Z
• rerunning release publish:
  • main dev bump step should no-op when main already has target dev version

Rerun is allowed for recovery, but must be announced in release channel/chat.

8) Hard rules and prohibitions

Do:

• use PRs for all code changes
• keep channel promotions deterministic and force-push only through approved promotion workflows
• require green CI before promotions
• document exceptions in PR description

Do not:

• manually retag or overwrite release tags
• manually edit package.json version outside defined release flow
• merge feature PRs into next during freeze
• skip the next/release -> main backport for RC fixes or hotfixes
• force-push next or release manually outside promotion workflows

9) Incident handling

If an incorrect promotion happened:

1. Stop further promotions immediately.
2. Announce incident and current branch SHAs.
3. Create corrective PRs (do not use destructive git history rewrites on protected branches).
4. Re-run affected workflows only after corrective PRs are merged.

10) Operator checklist (quick)

Before main -> next:

• main CI green
• freeze status known
• release manager approval
• branch rules allow workflow --force-with-lease on next

Before next -> release:

• RC validation complete
• all RC fixes merged to next
• corresponding backports to main completed or queued with owners
• branch rules allow workflow --force-with-lease on release

After stable release:

• verify stable artifacts exist
• merge auto PR for next -dev bump in main
• publish AUR update (PKGBUILD + .SRCINFO)
• announce cycle close

For post-release hotfix:

• patch target decided: X.Y.(Z+1)
• hotfix override for next announced
• fix merged to release patch line
• hotfix backport PR to main merged
• next restored to normal next-minor line

Nix note:

• nix-npm-deps-hash-sync.yml runs on pushes to main, next, and release.
• verify-nix in channel publish still performs full lock/hash refresh verification for release artifacts.
• Channel-local nix refresh PRs are advisory and can be overwritten by later reset-based promotions.
• If a nix refresh must survive release cycles, ensure the same change is merged into main.
