Release runbook

Cut, verify, and repair an Akron release across every public release surface.

Use this when cutting or repairing an Akron release.

Goal

Ship one version consistently across the GitHub tag, GitHub Release, GameBanana mod page, README install links, and akron.micr.dev.

The GitHub tag is the source of truth. A release is complete only after every required public surface has been confirmed updated. If one surface is stale after publishing starts, treat the release as partially published and repair it from the same tag.

Release contract

Required public surfaces:

• GitHub tag: vX.Y.Z
• GitHub Release: readable title, notes, Akron-vX.Y.Z.zip, its .zip.sha256 checksum, the .dependencies.json dependency manifest, and the .cdx.json CycloneDX SBOM
• GameBanana: release update and downloadable file for the same tag
• README: Olympus one-click handoff and raw-download links point at Akron’s stable install endpoints
• akron.micr.dev: docs are current, install endpoints resolve to the published release, and fallback GameBanana file ids point at the published file

Tags and artifact names stay canonical because external links use them. Public titles and changelog headings can use readable names such as Akron Beta 42. Do not mint a replacement tag for a sync or publishing failure unless rollback or unpublish has been explicitly chosen. Normal recovery repairs the same tag.

Deterministic path

The prepare, publish, and completion phases below are scripted. The prose sections stay authoritative for what each step means and for repairing a partial publish; the scripts are how a normal release runs them.

1. Write the release notes into the changelog’s ## Unreleased section as work merges. This is the one judgment step no script owns.
2. Cut the release:

scripts/release/cut-release.sh X.Y.Z

The script refuses a dirty tree, a stale main, an existing tag, an unbumped version, or an empty Unreleased section, then moves the notes under the release heading, bumps everest.yaml, runs make preflight-release, checks the package contents contract, commits, pushes main, and pushes the tag. main and v* tags are admin-bypass only by ruleset, so the cut runs locally as the release owner; everything after the tag is Actions.

3. The tag triggers the Release workflow as before. When it completes, the Verify Release workflow runs scripts/release/verify-release.sh against the tag: release assets, checksum, zip integrity, the GameBanana update, both akron.micr.dev install endpoints, byte-identity between the GameBanana file and the GitHub release zip, and the README links. A stale surface fails that run instead of waiting for someone to remember a check. The same script runs locally, and the workflow can be dispatched with tag_name when repairing an old tag.

Required configuration

See Release Configuration for the non-secret configuration matrix.

release-build environment variable:

• AKRON_CELESTE_REFS_SHA256: lowercase SHA-256 digest of the exact Celeste reference archive used by CI and release builds.

Repository variables:

• GAMEBANANA_SUBMISSION_ID: optional GameBanana publisher override. The workflow defaults to Akron’s mod id, 681169. Link sync uses its own fixed Akron mod id unless AKRON_GAMEBANANA_MOD_ID is passed to the sync script.
• GAMEBANANA_USER_AGENT: optional browser user agent replayed by the GameBanana publisher when the stored auth was captured with a browser profile that GameBanana expects to see again.
• TAILSCALE_EXIT_NODE: optional Tailscale exit node name or Tailscale IP used to route GameBanana publishing through a trusted network.
• TAILSCALE_TAGS: optional comma-separated Tailscale tags for the ephemeral Actions node. Defaults to tag:ci.

For local or manual publishing, GAMEBANANA_BROWSER can select the browser automation package. The GitHub release workflow pins this value to cloakbrowser; it is not a repository variable.

release-build environment secrets:

• AKRON_CELESTE_REFS_URL: archive containing the stripped Celeste references needed by CI.
• AKRON_CELESTE_REFS_TOKEN: optional token for the Celeste reference archive.

release environment secrets:

• AKRON_WEBSITE_TOKEN: token with contents:write access to Microck/akron-website.
• GAMEBANANA_COOKIES: base64-encoded JSON cookie export for GameBanana. This can be a Playwright storage state, an array of cookie objects, or a simple object of cookie names to values.
• GAMEBANANA_STORAGE_STATE_B64: base64-encoded Playwright storage state for a manually verified GameBanana session.
• GAMEBANANA_STORAGE_STATE_B64_GZ: gzip-compressed and base64-encoded Playwright storage state. Use this instead of GAMEBANANA_STORAGE_STATE_B64 if the plain base64 value exceeds GitHub’s 48 KB secret limit.
• GAMEBANANA_USERNAME and GAMEBANANA_PASSWORD: optional fallback credentials for local/manual runs and automated retries when stored authentication cannot edit the submission. The workflow still requires cookie or storage-state authentication at startup because direct username/password authentication on GitHub-hosted runners can trigger GameBanana’s UNKNOWN_DEVICE captcha.
• TS_OAUTH_CLIENT_ID and TS_OAUTH_SECRET: required only when TAILSCALE_EXIT_NODE is set. The OAuth client must be allowed to create tagged auth keys for the configured TAILSCALE_TAGS.

The workflow checks required publishing configuration before publishing to GameBanana or creating/updating the GitHub Release.

Preflight

1. Merge approved work into main.
2. Confirm main is green.
3. Pick the release version X.Y.Z.
4. Audit every commit since the previous release tag before writing release notes:

release_ref="${RELEASE_REF:-HEAD}"
previous_tag="$(git describe --tags --abbrev=0 --match 'v*' "${release_ref}^")"
git log --reverse --decorate --oneline "${previous_tag}..${release_ref}"
git log --reverse --format='%h %s%n%b' "${previous_tag}..${release_ref}"
git diff --name-status "${previous_tag}..${release_ref}"

For each commit in that range, either add a concrete user-facing note to the new CHANGELOG.md section or write down why it is intentionally omitted, such as a test-only, docs-only, CI-only, or internal refactor commit. Do not leave notes for commits after previous_tag under the previous version’s changelog section. If a commit message references issues or feedback, inspect that commit before summarizing it; do not rely on the latest commit alone.

5. Update CHANGELOG.md before tagging. The workflow extracts release notes from a readable heading such as ## Akron Beta 42, the canonical ## X.Y.Z, or their bracketed equivalents; the matching section must exist and must cover the audited commit range.
6. Update docs under docs/ for user-facing changes.
7. Check for hardcoded version, file id, or release text references that need to change.
8. Run the local release preflight:

make preflight-release

make preflight-release checks formatting for AkronFeatureRegistry.cs and its registry tests without rewriting files, builds, tests, packages Akron.zip, and verifies the zip can be read. If that focused formatting check fails, run make format, inspect the diff, and rerun the preflight. Format other changed C# files with dotnet format Akron.sln --include <changed-csharp-files>.

Package contents contract

Before publishing, the release package must be a valid zip and contain the expected Everest mod payload.

Required contents:

• everest.yaml
• bin/Akron.dll
• bin/ImGui.NET.dll
• bin/runtimes/linux-x64/native/libcimgui.so
• bin/runtimes/osx/native/libcimgui.dylib
• at least one Windows cimgui.dll runtime under bin/runtimes/
• Dialog/English.txt
• LICENSE
• ThirdPartyNotices.txt

Check the local package:

make package
unzip -l Akron.zip

Missing required contents means do not publish. Fix packaging first.

The packaged LICENSE and ThirdPartyNotices.txt must be byte-identical to the repository copies. Akron-owned material uses CC BY-NC-ND 4.0, while the components identified in the notices retain their original licenses.

Publish

1. Push main.
2. Create and push the tag:

git tag vX.Y.Z
git push origin vX.Y.Z

3. The tag triggers .github/workflows/release.yml. You can also rerun the Release workflow manually with tag_name set to the existing tag and prerelease set as needed.

What the workflow does:

• checks out the tag
• restores Celeste reference DLLs
• restores, builds, and tests Akron
• verifies Akron.zip, copies it to Akron-<tag>.zip, and writes a SHA-256 file
• writes a dependency manifest and CycloneDX SBOM for the release package
• extracts release notes from CHANGELOG.md
• checks publishing configuration
• publishes the release update and zip to GameBanana
• creates or updates the GitHub Release
• syncs README GameBanana links on main
• syncs Microck/akron-website fallback GameBanana file ids

Completion checks

A release is complete only after all checks pass.

1. GitHub Release:

gh release view vX.Y.Z -R Microck/Akron
gh release download vX.Y.Z -R Microck/Akron --pattern 'Akron-vX.Y.Z*' --dir /tmp/akron-release-check
(cd /tmp/akron-release-check && sha256sum -c Akron-vX.Y.Z.zip.sha256)
unzip -t /tmp/akron-release-check/Akron-vX.Y.Z.zip

2. Workflow health:

gh run list -R Microck/Akron --workflow Release --limit 5
gh run list -R Microck/Akron --workflow 'Sync GameBanana README Links' --limit 5

3. GameBanana:

• Verify the rendered mod page shows the new release/update.
• Verify the latest file is downloadable and matches the released version.
• Verify https://akron.micr.dev/olympus resolves to the current everest: install URL and https://akron.micr.dev/raw resolves to the new raw download file.

4. README:

grep -n 'akron.micr.dev/olympus\|akron.micr.dev/raw' README.md

Confirm the image buttons point at Akron’s stable install endpoints.

5. akron.micr.dev:

• Verify the rendered public site reflects the released docs.
• Verify install/download links resolve to the current GameBanana file.
• Verify any changed docs pages render correctly.

Rendered public pages should be checked with a browser-capable CLI or agent workflow when possible. API and text checks are useful, but they do not catch stale rendered content, broken layout, or bad public links.

Partial publish recovery

Use the same tag for recovery unless rollback/unpublish has been explicitly chosen.

Release workflow failed before GameBanana publishing

No public release should exist yet. Fix the configuration, changelog, package, or build failure, then rerun the existing tag:

gh workflow run release.yml -R Microck/Akron -f tag_name=vX.Y.Z -f prerelease=false

GameBanana failed

Inspect the failed workflow logs and the uploaded gamebanana-debug-vX.Y.Z artifact. Common causes are expired storage state, missing edit permission, captcha/permit pages, or an untrusted runner IP.

If the stored session is invalid, refresh the storage state using the storage-state procedure below, update the secret, and rerun the release workflow for the same tag.

If the runner IP is the issue and TAILSCALE_EXIT_NODE is configured, verify that the workflow reports the configured exit node as active and confirms HTTPS egress before treating the cookie as bad.

GitHub Release failed after GameBanana succeeded

Rerun the release workflow for the same tag. The workflow updates existing GameBanana/GitHub state where possible and uploads release assets with --clobber.

gh workflow run release.yml -R Microck/Akron -f tag_name=vX.Y.Z -f prerelease=false
gh release view vX.Y.Z -R Microck/Akron

README link sync failed

Run the sync workflow or run the script locally after identifying the intended GameBanana file id:

gh workflow run sync-gamebanana-readme-links.yml -R Microck/Akron
AKRON_GAMEBANANA_FILE_ID=<file-id> bash scripts/sync-gamebanana-readme-links.sh

Commit and push the README update if running locally.

akron.micr.dev link sync failed

Inspect the Sync Akron website GameBanana links step. The usual causes are a missing or under-scoped AKRON_WEBSITE_TOKEN, a changed website source path, or a stale GameBanana file id.

Verify the website repository state:

gh repo view Microck/akron-website
gh run list -R Microck/Akron --workflow Release --limit 5

If the release workflow already published GameBanana and GitHub successfully, repair the website from the same file id and tag. Do not create a new Akron release.

Rendered public pages are stale

First distinguish deployment delay from wrong source state:

• Check the committed README and Microck/akron-website source values.
• Check the rendered pages again after the deployment window.
• If source is wrong, repair the source and redeploy.
• If source is right but rendered output is stale, inspect the website deployment provider before changing release assets.

Exceptional rollback or unpublish

Rollback or unpublish is not the normal path for release failures. Use it only after an explicit decision, because deleted or replaced public releases can confuse users, external links, and GameBanana/Olympus install state.

Prefer repairing the same tag when the issue is auth, upload, README sync, website sync, or rendered-page staleness.

Optional Tailscale exit node

Use this when local verification accepts the stored GameBanana session but GitHub-hosted runner IPs reject the same cookies.

On the trusted network that can use the GameBanana session, advertise an approved host as a Tailscale exit node:

sudo tailscale up --advertise-exit-node

Approve the advertised exit node in the Tailscale admin console. Disable key expiry for that connector if it is meant to support unattended releases.

Create a Tailscale OAuth client with the writable auth_keys scope and a tag such as tag:ci. Add a matching ACL tag owner rule in Tailscale if needed, then store the credentials:

gh secret set TS_OAUTH_CLIENT_ID -R Microck/Akron --env release
gh secret set TS_OAUTH_SECRET -R Microck/Akron --env release
gh variable set TAILSCALE_TAGS -R Microck/Akron --body tag:ci
gh variable set TAILSCALE_EXIT_NODE -R Microck/Akron --body <exit-node-name-or-100.x.y.z>

The release workflow joins the tailnet before GameBanana publishing, checks that Tailscale reports TAILSCALE_EXIT_NODE as the active exit node, and confirms HTTPS egress. It does not print the Tailscale status or public IP.

GameBanana storage state size

Treat every captured storage-state file as a credential. Restrict the full state before reading or deriving another file from it:

umask 077
chmod 600 gamebanana-storage-state.json

Before setting the secret, verify the captured state can open the Akron edit form without a permit or captcha page:

npx playwright codegen --browser=chromium \
  --load-storage=gamebanana-storage-state.json \
  https://gamebanana.com/mods/edit/681169

Only continue once the loaded browser is visibly authenticated as the Akron owner and can edit the mod. A state that only passes Cloudflare but cannot edit 681169 will still fail in GitHub Actions because direct username/password login triggers GameBanana UNKNOWN_DEVICE.

Do not upload a full browser profile state if it is too large for GitHub secrets. Keep only GameBanana cookies first:

jq -c '
  {
    cookies: [
      .cookies[]
      | select((.domain | ltrimstr(".")) | endswith("gamebanana.com"))
    ],
    origins: []
  }
' gamebanana-storage-state.json > gamebanana-storage-state.min.json

chmod 600 gamebanana-storage-state.min.json

npx playwright codegen --browser=chromium \
  --load-storage=gamebanana-storage-state.min.json \
  https://gamebanana.com/mods/edit/681169

base64 < gamebanana-storage-state.min.json | tr -d '\n' \
  | gh secret set GAMEBANANA_STORAGE_STATE_B64 -R Microck/Akron --env release --body-file -

If the minified state does not open the edit form, do not set it as GAMEBANANA_STORAGE_STATE_B64. Store the verified full state through the compressed secret instead:

gzip -9c gamebanana-storage-state.json | base64 | tr -d '\n' \
  | gh secret set GAMEBANANA_STORAGE_STATE_B64_GZ -R Microck/Akron --env release --body-file -

If the minimized cookie state is still larger than 48 KB, store the gzip form:

gzip -9c gamebanana-storage-state.min.json | base64 | tr -d '\n' \
  | gh secret set GAMEBANANA_STORAGE_STATE_B64_GZ -R Microck/Akron --env release --body-file -

After the environment secret is stored and verified, remove the local credential files or move the full state into an approved secret store:

rm -f gamebanana-storage-state.min.json gamebanana-storage-state.json
