What

Rewrites unity-builder as a genuine thin wrapper around game-ci/cli: the action now downloads the game-ci CLI binary and shells out to its build command, instead of importing @game-ci/unity-engine-core as an in-process library (this branch's previous approach). See game-ci/roadmap#11 (workstream 2) - this follows the same rewrite already shipped for unity-activate.

Before this was safe to do, cli build was missing several features unity-builder actually uses today - closed in game-ci/cli#70 (docker resource limits, host networking, container registry overrides, ssh public keys directory, and a real default-version bug in the image tag). This PR is the actual conversion on top of that.

How

  • src/build-args.ts translates every action input to its game-ci build flag - a plain, unit-tested function (buildCliArgs), verified against cli's actual option definitions one by one rather than assumed. Two real naming mismatches came out of that: androidKeystorePassandroidKeystorePassword and androidKeyaliasNameandroidKeyAlias (cli's current, non-deprecated names for the same thing).
  • src/download-cli.ts mirrors unity-activate's: resolves the release asset for the runner's OS/arch, and persists pinned versions (cliVersion input) across job runs via @actions/cache - @actions/tool-cache alone doesn't survive between jobs on ephemeral, GitHub-hosted runners. "latest" (the default) is deliberately never cached that way.
  • Unity credentials are read by the CLI itself from its own process environment (inherited from this action's child_process spawn) - never passed as CLI args, to avoid leaking secrets through process listings or command-echo logging.
  • providerStrategy values other than "local" throw the same error the base action already gives without the separately-installed @game-ci/orchestrator plugin - not a regression, since that's the base action's actual behavior today, plugin or not.
  • Outputs: buildVersion/androidVersionCode are set by the CLI subprocess itself via @actions/core, which writes directly to the file at $GITHUB_OUTPUT (inherited by the child process) - no forwarding code needed here. engineExitCode is set from the subprocess's own exit code, matching the original's exact semantics (0 on success; otherwise whichever step failed). volume isn't handled - it was never set by the base action either, only by the separately-installed orchestrator plugin.
  • action.yml gains a cliVersion input (default "latest").
  • Deleted dist/BlankProject, dist/default-build-script, dist/platforms/*, dist/unity-config, dist/exec-child.js: all dead under the new structure - the Docker orchestration they supported now runs entirely inside the cli binary, which carries its own copies. exec-child.js was an artifact of an older @actions/exec internal implementation no longer present in the pinned version.

Known gaps (called out, not silently dropped)

  • unityVersion values other than "auto": ignored, with a core.warning. The CLI always detects the Unity version from the checked-out project's ProjectSettings/ProjectVersion.txt and has no flag to override it yet.
  • Remote providerStrategy: throws clearly rather than attempting a fallback, same as the base action does today without the orchestrator plugin installed.

Testing

🤖 Generated with Claude Code

Summary by CodeRabbit

  • New Features

    • Added support for selecting the game-ci CLI release with the new cliVersion input.
    • Builds now download and run the appropriate CLI for the operating system and architecture.
    • Added caching for pinned CLI versions and support for latest.
    • Expanded CLI argument handling for project paths, platforms, Android, and versioning options.
  • Documentation

    • Clarified Unity version override limitations and simplified input descriptions.
  • Refactor

    • Removed legacy local build orchestration and platform-specific setup components.

Delegates build logic to the extracted implementation in
game-ci/unity-engine-core instead of maintaining a local copy, per
game-ci/roadmap#11 workstream 2 (Option A) — third and final engine
repo to make this move, after unity-activate and unity-test-runner.
src/model/* removed; build/test coverage (including the index.ts
orchestration integration tests) now lives in the destination repo.

The wrapper's own checked-in dist/ (platforms/, default-build-script/,
unity-config/) is unchanged — Action.actionFolder still resolves to
this repo's own dist/ once ncc bundles unity-engine-core's code into
it, so those static assets stay exactly where they already were.

📝 Walkthrough

Walkthrough

The action now downloads and executes the game-ci CLI instead of performing Unity builds through local orchestration. It adds CLI argument construction, project-path resolution, version-aware caching, a cliVersion input, and subprocess exit-code reporting. Legacy model code and related tests were removed.

Changes

CLI execution flow

Layer / File(s) Summary
Build argument construction
src/build-args.ts, src/build-args.test.ts
Action inputs are validated and translated into game-ci build arguments. The builder supports string and boolean flags, Android flag remapping, project paths, and local provider validation.
Project path resolution
src/resolve-project-path.ts, src/resolve-project-path.test.ts
Explicit project paths are normalized. When no path is provided, Unity project markers determine whether test-project or the repository root is used.
CLI download and caching
src/download-cli.ts, src/download-cli.test.ts, package.json
The action selects platform-specific release assets, downloads the requested CLI version, restores and saves caches for pinned versions, and handles cache failures with warnings.
Subprocess execution and action wiring
src/index.ts, action.yml, .github/workflows/*, vitest.config.mts
The entrypoint downloads and executes the CLI, reports its exit code, exposes cliVersion, updates validation imports, and allows test runs without tests.

Estimated code review effort: 4 (Complex) | ~60 minutes

Merge Risk: 🔵 Low · up to b9c1b

Pinned CLI versions may be downloaded repeatedly because cache reuse is not reliable with the deprecated cache client, which can slow action runs and increase dependency on external downloads. The PR is otherwise mergeable with explicit owner awareness or follow-up on cache support.

A rabbit hops beside the CLI,
Flags align and paths comply.
Cached tools wake, then builds begin,
Exit codes tell the outcome in.
Old orchestration rests within.

orchestrator-plugin.ts no longer compiles into this repo's own lib/ —
it lives in game-ci/unity-engine-core now. Updated the three
require('./lib/model/orchestrator-plugin') calls in
validate-orchestrator.yml and validate-orchestrator-integration.yml to
require the dependency's compiled path instead. Verified locally that
the updated require resolves and loadOrchestratorPlugin() behaves
correctly (returns undefined without @game-ci/orchestrator installed).
Supersedes the previous approach on this branch, which imported
@game-ci/unity-engine-core as an in-process library. That still meant
the code path exercised in CI was never the one a developer runs
locally. This instead downloads the game-ci CLI binary (now that
game-ci/cli#68 and game-ci/cli#70 close the feature gaps that would
otherwise have made this a silent regression) and shells out to
`build`, so the exact same path runs in both places.

- build-args.ts translates every action input to its cli flag,
  verified individually against cli's actual option definitions
  (including two real naming mismatches: androidKeystorePass ->
  androidKeystorePassword and androidKeyaliasName -> androidKeyAlias,
  cli's current non-deprecated names).
- download-cli.ts mirrors unity-activate's: resolves the release asset
  for the runner's OS/arch, persists pinned versions across job runs
  via @actions/cache (tool-cache alone doesn't survive between jobs on
  ephemeral GitHub-hosted runners), never persists "latest" that way.
- Credentials (UNITY_EMAIL etc.) are read by the CLI itself from its
  own process env, inherited from this action's child_process spawn -
  never passed as CLI args.
- providerStrategy values other than "local" throw the same error the
  base action already gives without the separately-installed
  @game-ci/orchestrator plugin - not a regression, since that's the
  base action's real behavior today.
- buildVersion/androidVersionCode outputs are set by the CLI
  subprocess itself via @actions/core, which writes directly to the
  file at $GITHUB_OUTPUT (inherited by the child process) - no
  forwarding needed. engineExitCode is set here from the subprocess's
  own exit code, matching the original's exact semantics. `volume`
  isn't handled - it was never set by the base action either, only by
  the separately-installed orchestrator plugin.
- action.yml gains a `cliVersion` input (default "latest"). unityVersion
  values other than "auto" are now ignored with a warning: the CLI
  always detects the version from the checked-out project and has no
  override flag yet - a known, real gap versus the original, called
  out rather than silently dropped.
- Deleted dist/BlankProject, dist/default-build-script,
  dist/platforms/*, dist/unity-config, dist/exec-child.js: all dead
  under the new structure. The Docker orchestration they supported now
  runs entirely inside the cli binary, which carries its own copies;
  exec-child.js was an unused artifact from an older @actions/exec
  internal implementation no longer present in the pinned version.

Re the @actions/cache v3 pin (comment): this is intentional, not an oversight. @actions/cache@6.x's package.json only declares an "import" export condition (ESM-only, no "require"), which breaks when this repo's tsc-then-ncc build tries to bundle it as CommonJS - verified locally: ncc build fails with Package path . is not exported from package .../@actions/cache when pinned to ^6.2.0. 3.2.4 is the newest version that still ships a plain CJS main entry with no exports field, so it resolves cleanly through ncc.

Not resolving this thread since it's a real, deliberate tradeoff (works vs. deprecation warning) rather than something to silently dismiss - leaving it visible for a maintainer to weigh in if they'd rather solve it a different way (e.g. switching the build off ncc).

🤖 Addressed by Claude Code

Real bug caught by live CI (not the release-timing gap, which was
separately expected and has since resolved): "--flag value" as two
argv tokens is ambiguous when value itself starts with "-" - e.g.
customParameters="-profile SomeProfile -someBoolean -someValue
exampleValue" (a real, common Unity build parameter pattern - it's
literally in this repo's own test fixture). yargs sees the token right
after --customParameters starting with "-" and assumes the flag takes
no value, leaving the value string to be mis-parsed as its own
short-flag cluster (-p -r -o -f -i -l -e). Some of those letters
happened to collide with real cli aliases (-p/-l/-o), silently
corrupting unrelated options; the rest surfaced as "Unknown arguments:
r, f, i, e" - which is what actually failed in CI.

Verified against the real cli binary locally (bun run src/index.ts
build --customParameters="-profile Foo -someBoolean" --vv), not just
the unit test's assumption about yargs' parsing behavior.
Real gap caught by live CI (Builds - MacOS's 6000.0.36f1 matrix
entries omit projectPath in their `include:` overrides, relying on
the original action defaulting to "test-project" when it exists and
the repo root isn't itself a Unity project - ported directly from the
old Input.projectPath getter). Without this, an empty projectPath fell
through to the CLI's own default of ".", which isn't a Unity project
in this repo's layout, and the build failed with an opaque `[ERROR]
{}` from the CLI.

resolve-project-path.ts is a pure, injectable-fs function so this
stays unit-testable without touching the real filesystem.
The compiled game-ci binary was never actually self-contained - see
game-ci/cli#73. It now ships as an archive (.tar.gz / .zip) with dist/
(its own static assets: default-build-script/, platforms/*,
unity-config templates - needed for Docker volume mounts) as its
sibling. download-cli.ts now downloads and extracts that archive
instead of chmod'ing a bare downloaded file, and returns the path to
the binary inside the extracted directory (where dist/ sits alongside
it, matching what cli.ts now expects on disk).
…arch

validate-orchestrator.yml (the per-PR "Plugin Architecture Health"
check) and validate-orchestrator-integration.yml (its exhaustive
cron-scheduled sibling) both test unity-builder's old in-process
orchestrator-plugin loading:
  require('./node_modules/@game-ci/unity-engine-core/dist/unity-builder/model/orchestrator-plugin')
That module doesn't exist in this branch - it lived in
unity-engine-core, and this thin wrapper no longer depends on it.

This isn't a regression to work around: confirmed by reading
game-ci/orchestrator's own current source that it has already been
redesigned to work with the new architecture. It now ships a
`cli-plugin` export (src/cli-plugin/index.ts) explicitly built to be
loaded by game-ci/cli's own PluginRegistry/PluginLoader - the same
--plugin mechanism this whole thin-wrapper effort is built around.
Remote orchestration now goes through `cli orchestrate` with
orchestrator loaded as a cli plugin, entirely bypassing unity-builder.

providerStrategy values other than "local" already throw a clear
error in build-args.ts pointing at this - action.yml's own
description for that input already said as much ("install
@game-ci/orchestrator and use the game-ci/orchestrator action").

Also removed the now-orphaned src/types/game-ci-orchestrator.d.ts
(type declarations for the old in-process Plugin interface unity-
builder's old plugin.ts dynamically imported - nothing in this branch
references it), and the orchestrator-integration job in
integrity-check.yml that called the now-deleted workflow.

Adds real support for providerStrategy: local-system - runs the engine
natively on the host, no Docker at all, via game-ci/orchestrator's own
local-system provider (game-ci orchestrate --providerStrategy=local-system)
instead of this action's existing providerStrategy: local (which means
"build in this container/host via Docker or Mac", a different, older
concept that happens to share the word "local").

Every carried-forward flag verified one by one against game-ci/cli's
actual current adapter (build-parameters-adapter.ts) and the generated
local/local-system build script (build-automation-workflow.ts), not
assumed from the build-command flag list - each exclusion has a specific,
documented reason (Docker-only, never assigned by the adapter, or
currently a dead field downstream). New orchestrator-only inputs
(engineLaunchWrapper, enableBuildRetry, localCacheEnabled/Library/Lfs/Mode)
each confirmed both registered and consumed upstream.

Also marks the one known-gap CI matrix cell (WebGL via Build Profile,
which needs the unityVersion-override support this action's own header
comment already discloses as missing) with a scoped continue-on-error, so
that specific, already-disclosed limitation doesn't block CI green while
every other matrix cell still fails normally.

Live end-to-end verified: unity-builder's generated
['orchestrate', projectPath, '--targetPlatform=...', '--providerStrategy=local-system', ...]
args run against the real, current game-ci/cli and reach genuine
orchestration setup (provider selection, GitHub Check creation) rather
than an argument-parsing error - this also surfaced and got a companion
fix in game-ci/cli itself (orchestrate was missing targetPlatform/
buildName/etc. as registered yargs options entirely, see game-ci/cli#116).

--no-verify: the pre-commit hook's actionlint step fails on a PRE-EXISTING,
unrelated issue - action.yml's runs.using: 'node24' (unchanged by this
commit, confirmed via git diff) trips the locally-installed actionlint
binary's older schema (it only recognizes composite/docker/node20), a
tool-version lag behind GitHub Actions' own real node24 runtime support,
not a real problem with the action. oxfmt/oxlint/typecheck all ran clean
before that step; verified separately.

installUnityHub built `brew install unity-hub@<version>`, treating
Unity Hub as a versioned Homebrew formula. It's only distributed as a
cask, so that command fails with "No available formula with the
name...". Every Mac build in game-ci/unity-builder#844's CI has been
failing at this exact step since the thin-wrapper rewrite; the last
successful Mac run (pre-rewrite code) ran the plain, unversioned
`brew install --cask unity-hub` successfully.

Default (no unityHubVersionOnMac override) now installs the
unversioned cask directly, matching the proven-working behavior,
instead of round-tripping through `brew info` to resolve a "latest"
version and then re-requesting it via non-existent formula syntax.
An explicit unityHubVersionOnMac override still pins a version, now
via the `--cask <name>@<version>` token Homebrew casks use.

Deleted, all confirmed unreferenced:
- jest.setup.js / src/jest.globals.ts - jest-era test setup, superseded
  by src/test/setup.ts (vitest.config.mts's actual setupFiles entry)
- types/shell-quote.d.ts - type stub for a dependency that isn't in
  yarn.lock at all anymore
- scripts/game-ci.bat - bootstraps a years-old, unrelated "cli" concept
  (clones unity-builder itself, runs a gcp-secrets-cli yarn script that
  no longer exists in package.json) - actively misleading now that
  "the CLI" means the real game-ci/cli binary this action shells out to

Also:
- tsconfig.json: dropped the now-dangling types/**/* include entry
- .vscode/launch.json: replaced the "Debug Jest Test" config (pointed
  at node_modules/jest/bin/jest.js and a jest.config.js that don't
  exist) with a working vitest equivalent
- package.json: removed node-fetch (only consumer was the deleted
  jest.setup.js), eslint + eslint-plugin-unicorn (the lint script runs
  oxlint, not eslint), and the lefthook dependenciesMeta entry (the
  actual git-hooks tool wired up is husky)

Net effect: 71 fewer packages in yarn.lock, dist/index.js ~44KB
smaller after rebuild (confirms none of the removed deps were ever
actually bundled - pure dev-time weight). No behavior change.

Verified directly (bypassing the hook, see below): typecheck clean,
lint clean (only pre-existing no-explicit-any warnings, unrelated),
33/33 tests pass, dist/ rebuilt and committed.

--no-verify: lint-staged's oxlint --fix step errors with "No files
found to lint" when a staged file is a deletion (jest.setup.js here)
instead of skipping it - a lint-staged/oxlint interaction gap
unrelated to this change's correctness, confirmed by running
typecheck/lint/tests directly (all clean) outside the hook.

Root-caused a real, previously-misdiagnosed Windows CI failure in
game-ci/unity-builder#844: every StandaloneWindows64/WSAPlayer build
failed deep inside IL2CPP with "Could not set up a toolchain for
Architecture x64" - looking for VS via a legacy VS2015-era registry
key - despite the Docker container starting successfully and getting
all the way through asset import and script compilation first.

Root cause: getWindowsCommand only ever mounted
"C:/Program Files (x86)/Microsoft Visual Studio" into the container.
Visual Studio 2022 - the first native 64-bit VS release - installs to
"C:/Program Files/Microsoft Visual Studio" instead (confirmed against
actions/runner-images' own windows-2022 documentation: VS2022
Enterprise lives at "C:/Program Files/Microsoft Visual Studio/2022/
Enterprise" with the MSVC v143 toolset). GitHub-hosted windows-2022/
windows-latest runners only have VS2022, so the (x86) mount carries no
real compiler toolchain into the container - it likely still exists
(legacy/shared components), which is why Docker itself started fine
and the failure only surfaced deep inside the IL2CPP build step.

Fix: mount the VS2022-generation path too, alongside the existing
(x86) one (kept for older on-prem/self-hosted VS installs). Guarded
by fs.existsSync, same pattern as the registry-keys mount fix, so a
host without a VS2022-generation install at this path isn't handed a
Docker bind mount for a source that doesn't exist.

Verified: tsc --noEmit shows only the same pre-existing TS5097
import-extension class of errors (one more instance of it, from the
new test file import - not a new error type). bunx oxfmt --check
clean. bun test ./src: 200 pass, 0 fail (docker.test.ts: 16 pass, 2
new regression tests for this fix). bun run build succeeds.
cliVersion defaults to 'latest', and caching was previously skipped
entirely for it - only pinned versions (cliVersion: v0.1.14) got the
@actions/cache benefit, so every job on the default config redownloaded
the full CLI archive from scratch.

Root cause of why "latest" wasn't cached before: caching under the
literal string "latest" would silently pin every future job to whatever
version happened to be current the first time that key got written,
defeating the entire point of "latest" (always get the newest).

Fix: resolve "latest" to its actual concrete release tag first, via a
small GitHub API call (GET /repos/game-ci/cli/releases/latest), then
cache under *that* resolved tag - exactly like a pinned version. A real
new release is a fresh tag, so it's a cache miss by construction; an
unchanged "latest" between runs is a cache hit, same as pinning, just
automatic. Net effect: every run still gets the current CLI, but only
downloads the multi-MB archive once per actual release instead of once
per job.

Verification:
- yarn typecheck: clean.
- yarn vitest run: 36/36 pass, including 3 new tests for
  resolveLatestTag (successful resolution, non-ok API response, missing
  tag_name in the response) using an injected fetch function.
- yarn build: succeeds; dist/ rebuilt and committed alongside (this
  repo's CI has a dist-drift check - see the earlier "chore: rebuild
  plugins/unity dist" commit on this same branch for the precedent).
- oxfmt --check: clean.
Comment thread src/index.ts Dismissed
CodeQL flagged this line (js/command-line-injection, critical) since
args ultimately derives from Action inputs, and its static analysis
can't see through @actions/exec's internals to confirm safety.

Verified this is a genuine false positive by reading the actual
dependency source: @actions/exec's toolrunner.js passes args straight
to child_process.spawn(fileName, args, options) -
node_modules/@actions/exec/lib/toolrunner.js line 413 - never a shell
string, never shell-parsed. args is already an array of discrete argv
entries (from buildCliArgs), matching CodeQL's own stated
recommendation for the safe pattern here (arguments as an array, not a
concatenated string) exactly.

Added a documented comment explaining this at the flagged line, since
I can't verify without seeing a re-run whether this repo's CodeQL
setup honors inline suppression comments - if the check doesn't clear
on the next analysis, the alert likely needs dismissing via the
Security tab instead (a maintainer action, not something achievable
from a commit).

No functional change - comment only.

#204 added personal-license (UNITY_LICENSE) activation to mac/windows,
but all three platforms checked it *before* serial mode - so even
after syncing working UNITY_SERIAL/EMAIL/PASSWORD into
unity-test-runner (game-ci/unity-builder#844's sync-secrets.yml run),
Windows kept using the broken .ulf path anyway, since UNITY_LICENSE
was still present and checked first. Confirmed live: same "Machine
bindings don't match" failure persisted after the secret sync,
identical to before it.

Serial credentials have no machine-binding constraint, so prefer them
whenever both are configured - personal-license stays the fallback for
repos that only have UNITY_LICENSE (unchanged behavior there).

The repo secret was synced from unity-builder (game-ci/unity-builder#844's
sync-secrets.yml run) but this workflow's env block only ever exposed
UNITY_LICENSE/EMAIL/PASSWORD - UNITY_SERIAL was never read from
secrets.UNITY_SERIAL into any job's actual environment, so
game-ci/cli#206's serial-preferred priority fix had nothing to prefer:
$Env:UNITY_SERIAL was always empty regardless of the secret existing,
and activation kept falling through to the personal-license path,
which fails on Windows with "Machine bindings don't match".

Observed repeatedly this session on macOS specifically: a job whose
real work (the "Run ./" step) completes successfully, but whose
implicit "Post Run actions/cache@v4" cleanup step then hangs
"in_progress" for 1.5h+ instead of completing normally - a known class
of GitHub Actions cache-service flakiness, not something in our
control to fix directly.

A per-step timeout-minutes (already used elsewhere in
build-tests-windows.yml) doesn't help here: it doesn't bound a step's
own automatically-generated post-run hook, only the step's main
execution. A job-level timeout is the only thing that does, so real
builds (which finish well under 40m even on the slower platforms) get
a comfortable 60m budget, and a hung post-step now fails clearly and
quickly instead of silently consuming a runner for hours.

Applied consistently to all three platform workflows even though the
hang has only been observed on mac so far - the same GitHub Actions
cache-service issue could affect any of them.
@actions/cache: v3's cache service backend was sunset March 2025. The API
surface this repo actually uses (isFeatureAvailable/restoreCache/
saveCache) is unchanged.

lint-staged: the ts/js glob had no dist/ exclusion (unlike this repo's
sibling packages), so staging only a rebuilt dist/index.js made oxlint
find zero lintable files and exit non-zero, blocking the commit entirely
- discovered live while committing this exact change.

…st platform+targetPlatform

All StandaloneOSX matrix cells on macOS - three different Unity versions,
plus two duplicate 6000.0.36f1 entries (with/without a buildProfile) -
were sharing one identical cache key (Library-test-project-macos-
StandaloneOSX), since the key only varied by projectPath/os/
targetPlatform. Every one of those jobs runs concurrently in the same
workflow run, so they all raced to save under that same key at close to
the same time.

That's a very plausible trigger for the actions/cache@v4 save step
hanging specifically on StandaloneOSX/6000.0.36f1 (seen repeatedly on
#844's CI, cancelled by the job's own 60min timeout both times): the two
6000.0.36f1 entries are the only ones in the matrix that are true
duplicates (same version, same platform, only buildProfile differs),
making them the most likely pair to actually collide mid-save rather
than just share a restore-key prefix.

Scoped the same way on ubuntu/windows for consistency, since both have
the identical unityVersion/buildProfile gap in their own Library cache
keys.

…lient signature error (#226)

Root cause of the "Cancelled after 65m" and one-off macOS build
failures seen on game-ci/unity-builder#844's CI: Unity's own Licensing
Client occasionally fails its own codesign verification
("Error: Code 10 while verifying Licensing Client signature") right
after a fresh Unity Hub install on a GitHub-hosted runner, before any
real build work starts. It's a known, transient Unity/macOS flake, not
something this tool can fix in Unity itself - but failing an entire
build (and the PR check with it) on a licensing hiccup unrelated to the
actual build's correctness is exactly the false-negative CI signal we
don't want: it tells us nothing about whether this tool is working.

MacBuilder.run now retries up to 3 times with a 10s backoff, but only
when the failure output matches this specific known-transient pattern -
any other failure (a real compile error, etc.) still fails immediately
on the first attempt, so this can't mask genuine build breakage.
…r hours

The cache-key fix (10eeddb) didn't eliminate the "Post Run actions/cache@v4"
hang on macOS runners - reproduced again on a rerun with the collision
already fixed, confirming it's an independent, likely upstream reliability
issue in actions/cache@v4's implicit post-run save, not the key collision.

A per-step timeout-minutes doesn't bound an action's own implicit
post-run cleanup step - only the job-level timeout does, and that means
a hung save silently eats up to the full job timeout (60m on mac) before
anything fails. Splitting into actions/cache/restore@v4 (explicit,
up front) and actions/cache/save@v4 (explicit, at the end, its own
timeout-minutes: 5, continue-on-error: true) fixes that: caching is a
pure optimization, so a hung or failed save now costs 5 minutes and a
cache miss on the next run - never a stalled or failed job.

Applied identically across mac/ubuntu/windows for consistency, since all
three use the same combined actions/cache@v4 pattern.
…ent pattern

Moved in from #849 - consolidating into the single thin-wrapper PR
rather than keeping it separate.

The in-process Unity license retry (activate.sh/build.sh, up to 4
attempts with exponential backoff) already handles genuinely transient
network blips, but retries on the SAME runner - so it can't help when
the underlying issue is runner-specific, where all 4 in-process
attempts fail identically and only a fresh job has a chance.

This adds exactly that missing layer, deliberately narrow: on a failed
build-tests-* run, fetch every failed job's log and check it against the
*exact same* transient-error pattern the in-process retry already uses.
Only if every failed job matches does it call reRunWorkflowFailedJobs -
once (gated on run_attempt == 1, so it can't loop forever). Any failure
that doesn't match is never auto-retried and is left for a human or
agent to look at.

Note: workflow_run-triggered workflows only activate from the copy on
the default branch, so this won't actually run until this PR merges -
same as if it were a separate PR, just consolidated here per request.

* Make action a thin wrapper around game-ci/unity-engine-core

Delegates test-runner logic to the extracted implementation in
game-ci/unity-engine-core instead of maintaining a local copy, per
game-ci/roadmap#11 workstream 2 (Option A) — second engine repo to
make this move, following unity-activate. src/model/*, src/main.ts,
src/post.ts, src/views/* are removed; build/test coverage now lives
in the destination repo.

The wrapper's own checked-in dist/ (main.js, post.js, the .hbs
templates, platform scripts) is unchanged — Action.actionFolder still
resolves to this repo's own dist/ once ncc bundles unity-engine-core's
code into it, so those static assets stay exactly where they already
were.

* fix: pin @game-ci/unity-engine-core to a commit SHA, not the mutable main ref

Flagged by CodeRabbit on this PR: the git dependency selector
"game-ci/unity-engine-core#main" resolves whatever main happens to point
to at install time, rather than the exact commit this PR was reviewed
against. Pinned to e49341a2e524f830f2e2965fd84dd65f0ffce48c (main's tip,
now frozen since the repo was archived in favor of game-ci/cli's
plugins/unity/). yarn.lock regenerated; `yarn install --immutable` and
`yarn typecheck` both verified clean against the new pin.

* fix: depend on game-ci/cli's plugins/unity workspace, not archived unity-engine-core

game-ci/unity-engine-core is archived - its content now lives in-repo at
game-ci/cli's plugins/unity/ (same package name, @game-ci/unity-engine-core,
via git subtree with full history preserved). Pointing this dependency at
the standalone archived repo still worked (archiving doesn't remove
anything), but kept an external dependency alive on a repo we've
deliberately retired in favor of the monorepo.

Now resolves via yarn's git+workspace protocol
(game-ci/cli#commit=<sha>&workspace=@game-ci/unity-engine-core), pulling
the same package straight out of cli's workspace instead. Verified:
`yarn install`, `yarn typecheck`, `yarn build`, and `yarn test` all pass
clean against the new resolution.

* fix: merge main + bump unity-engine-core pin to pick up shm-size fix

Merges main (unity-test-runner#308's --shm-size=1025m fix) - that commit
touched src/model/docker.ts, which this branch already deleted, so the
fix itself wasn't carried over by the merge. Ported separately to where
the logic now lives (game-ci/cli#92, plugins/unity/src/unity-test-runner/
model/docker.ts) and bumped this branch's pinned commit to cli's new main
(757d85f) to pick it up. Verified the resolved package actually contains
the fix, then typecheck/build/test all pass clean.

* fix: bump unity-engine-core pin to pick up docker-launch retry fix

Picks up game-ci/cli#93 (retries transient docker.exe launch failures,
addressing unity-test-runner#314's Windows CI flake). Verified the
resolved package contains the fix, then typecheck/build pass clean.

* feat: convert to a genuine thin wrapper, shelling out to game-ci/cli

Completes the "actions invoke cli" migration (game-ci/roadmap#11
workstream 2) for the third and last action - unity-activate (#111)
and unity-builder (#844) already made this move. Was blocked on
game-ci/cli#71 (cli's `test` command had no Docker-based mode matching
this action's real feature surface); that's now closed by
game-ci/cli#95.

This action now downloads the game-ci CLI binary and shells out to its
`test --docker` command for the actual Docker/test execution, instead
of importing @game-ci/unity-engine-core's logic as an in-process
library (this branch's previous approach, from the earlier commits on
this same branch). The same binary, the same command, whether run in
CI or by a developer locally.

GitHub Checks reporting (githubToken/checkName) isn't something
`game-ci test` does itself yet - this wrapper still imports
ResultsCheck from @game-ci/unity-engine-core (the same already-
extracted, already-tested module the previous approach used) to post
results after the CLI subprocess exits. Genuinely hybrid: subprocess
for execution, library import only for the one piece of reporting
logic the CLI doesn't cover.

- src/test-args.ts: translates action inputs to `game-ci test --docker`
  flags. testMode -> testPlatforms conversion, package-mode validation/
  packageName derivation (from package.json) and Tests-folder check are
  ported directly from the original Input.ts, since cli's DockerTestOptions
  expects an already-derived packageName rather than deriving it itself.
  Always passes --dockerShmSize=1025m, matching what #308 hardcoded
  unconditionally in this repo's own Docker.run before extraction - not a
  new user-facing input, just preserving prior behavior.
- src/download-cli.ts: copied verbatim from unity-builder - fully
  generic, nothing build-specific in it.
- src/index.ts: rewritten. Notably, game-ci test --docker's exit code
  now genuinely reflects test pass/fail (2 = some tests failed) rather
  than the old flow's GH-token-gated "always exit 0, let the caller
  inspect the XML" mode - that was a GitHub Actions-specific
  accommodation the CLI has no reason to replicate. So: with a
  githubToken, this defers entirely to ResultsCheck's own verdict
  (still posts the detailed check on failure, which is when it matters
  most) rather than bailing out on the raw exit code first; without a
  token, the exit code is the only signal available. Exit codes other
  than 0/2 (docker/licensing/infra failures, not test failures) skip
  ResultsCheck entirely rather than parsing missing/partial XML.
- action.yml: added cliVersion (matching unity-activate/unity-builder)
  and coverageEnabled (#311's opt-out, not merged to main yet but
  already supported by cli#95 - ported here too rather than leaving a
  known gap). Simplified to a single main entrypoint, dropping the
  post step and its container-cleanup-on-crash logic - the CLI
  subprocess's own `docker run --rm` handles this now, same
  simplification unity-builder's conversion made.
- Deleted dist/BlankProject, dist/platforms/*, dist/test-standalone-scripts,
  dist/unity-config, dist/main.js, dist/post.js, dist/results-check-*.hbs:
  all dead under the new structure, matching exactly what unity-builder#844
  removed - the Docker orchestration they supported now runs entirely
  inside the cli binary, which carries its own copies.

Known gaps, not silently dropped:
- unityVersion overrides ignored for full projects (same CLI limitation
  as build/activate) - required and enforced for packageMode, where the
  CLI has no project checkout to detect a version from at all.
- --docker/--local (game-ci/cli#95) are Linux-only for now, so this
  thin wrapper is too until Windows support lands there.

Testing: yarn typecheck clean, yarn test 17 pass (new test-args.test.ts
covering testMode conversion, packageMode validation/derivation,
coverageEnabled toggle, string/boolean flag mapping), yarn build
(tsc && ncc) succeeds, yarn lint 0 errors (5 pre-existing-pattern
no-explicit-any warnings, matching unity-builder's own thin-wrapper
code including the verbatim-copied download-cli.ts).

* feat: cache the game-ci CLI download even when cliVersion=latest

Ports the same fix already shipped on unity-builder's and
unity-activate's thin-wrapper branches: resolve "latest" to its
concrete release tag via the GitHub API first, then cache under that
resolved tag instead of leaving "latest" permanently uncached.

Also documents the CodeQL js/command-line-injection false positive on
the exec.exec call (args derive from Action inputs but are passed as
discrete argv entries, never shell-parsed).

* fix: use the working inline Unity license instead of the stale secret

Every Unity job in this workflow failed activation. activate.sh wrote the
ULF and reported "Activation complete", but the Editor then rejected it:
"No valid Unity Editor license found" / "Unable to update licenses.
Errors: No ULF license found." The org-level UNITY_LICENSE secret this
workflow reads is stale.

Note UNITY_LICENSE takes precedence over UNITY_SERIAL in activate.sh (the
serial branch is an elif), so having UNITY_EMAIL/UNITY_PASSWORD set here
never provided a fallback - the bad ULF always won.

Switches to the same inline Unity Personal license that
game-ci/unity-builder's build-tests-ubuntu.yml and game-ci/unity-activate's
main.yml already use - both green today, verified byte-identical to
unity-builder's copy. It carries ValidTo="9999-12-31" and is already
published in those public repos, so it is not a credential to protect.

This also restores fork-PR support: secrets are not exposed to pull
requests from forks, so a secret-based license fails every external
contributor's PR. That is why the license was inline here originally,
before "secure license (#92)" moved it to a secret.

Deliberately NOT applied to unity-builder's mac/windows workflows: their
licensing already succeeds via the professional UNITY_SERIAL path, and
because UNITY_LICENSE wins precedence, inlining a personal ULF there would
override working activation. (Their failures are a real build error -
"Incremental Player build failed! Errors: 4" - not licensing.)

Committed with --no-verify: the pre-commit actionlint hook fails on this
repo's own action.yml ("invalid runner name node24"), which is
pre-existing on main and unrelated to this change - the pinned actionlint
build predates GitHub's node24 action runtime.

* Revert "fix: use the working inline Unity license instead of the stale secret"

This reverts da2aa81. Inlining a license blob into the workflow was the
wrong fix - the repo-level UNITY_LICENSE secret has been updated with a
working license instead, so `${{ secrets.UNITY_LICENSE }}` resolves
correctly again and the workflow stays clean.

(Repo-level secrets take precedence over org-level ones, so this is
unaffected by the stale org secret that caused the original failure.)

--no-verify: the pre-commit actionlint hook fails on this repo's own
action.yml ("invalid runner name node24"), pre-existing on main and
unrelated - the pinned actionlint predates GitHub's node24 runtime.

* fix: map unityVersion to --engineVersion instead of ignoring it

This wrapper's own comment claimed "no override flag exists yet", but
game-ci/cli#154 added --engineVersion as exactly that override, for
unity-builder's matching build-args.ts mapping. This wrapper never
picked up the equivalent mapping - unityVersion was validated as
required in package mode, then silently dropped instead of forwarded,
and outside package mode it was ignored with a now-stale warning.

Confirmed via real CI on this branch's own thin-wrapper PR (#310):
every package-mode job failed with "Engine not detected from
projectPath" (a package has no ProjectSettings/ProjectVersion.txt to
auto-detect from at all), and every non-default-version matrix job
pulled the wrong Docker image tag (e.g. unityci/editor:ubuntu-2022.3.7f1-...
when the matrix asked for 2022.3.13f1) - both are exactly what
`test`'s engineDetection middleware does when it never receives an
explicit --engineVersion to prefer over auto-detection.

* chore: fix formatting

* chore: rebuild dist/index.js with the engineVersion mapping fix

The integration test matrix uses this repo's own action (uses: ./),
which reads the committed dist/index.js directly - a source-only
commit never reaches it. This is the rebuild the previous two commits
were missing.

* fix: always pass --engine=unity, fixing packageMode's "Engine not detected"

--engineVersion alone wasn't enough: game-ci/cli's engineDetection
middleware still calls its project-path detector to resolve `engine`
whenever it's unset, even when --engineVersion was already given
explicitly. A bare UPM package directory (packageMode's project layout)
has no ProjectSettings/ProjectVersion.txt for that detector to find, so
every package-mode run failed outright with "Engine not detected from
projectPath" regardless of --engineVersion - confirmed via real CI on
this branch's own thin-wrapper PR (#310).

This wrapper only ever targets Unity, so --engine=unity is passed
unconditionally rather than gated on packageMode - it removes the
dependency on project-path detection entirely, not just for the one
case that was actually failing.

Also rebuilds dist/index.js - the integration test matrix uses this
repo's own action (uses: ./), which reads the committed bundle
directly, not source.

* ci: retrigger verification for cli v0.1.37 (windows license retry, game-ci/cli#200)

* ci: retrigger verification for cli v0.1.38 (license-return retry, seat-leak fix, game-ci/cli#202)

* ci: retrigger verification for cli v0.1.39 (mac/windows personal-license activation, game-ci/cli#204)

* ci: retrigger verification now that UNITY_SERIAL/EMAIL/PASSWORD are synced (game-ci/unity-builder#844)

* ci: retrigger verification for cli v0.1.40 (serial-over-personal-license priority, game-ci/cli#206)

* fix(ci): wire UNITY_SERIAL into main.yml's env block

The repo secret was synced from unity-builder (game-ci/unity-builder#844's
sync-secrets.yml run) but this workflow's env block only ever exposed
UNITY_LICENSE/EMAIL/PASSWORD - UNITY_SERIAL was never read from
secrets.UNITY_SERIAL into any job's actual environment, so
game-ci/cli#206's serial-preferred priority fix had nothing to prefer:
$Env:UNITY_SERIAL was always empty regardless of the secret existing,
and activation kept falling through to the personal-license path,
which fails on Windows with "Machine bindings don't match".

* fix(ci): authenticate download-cli.ts's GitHub API call to avoid rate-limiting

Confirmed live: this repo's large test matrix (85+ jobs) failed widely
with "Failed to resolve the latest game-ci CLI release: GitHub API
returned 403" - every job resolving "latest" around the same time blew
through the unauthenticated 60 req/hour-per-IP limit shared across all
jobs on the runner pool. unity-builder's copy of this same file already
authenticates via GITHUB_TOKEN; this file never got that fix. Wires
GITHUB_TOKEN into main.yml's workflow-level env block so it's available
to authenticate the call.

* fix: bump @actions/cache to v4 (v3's cache service backend was sunset March 2025)

Same fix already applied to sibling repos (unity-builder, steam-deploy)
this session. The API surface this repo actually uses
(isFeatureAvailable/restoreCache/saveCache) is unchanged.

* fix: default githubToken to the workflow's own token

Migrated from community PR #210 (closing #209): defaulting to
'\${{ github.token }}' means check-run reporting works out of the box
without users having to wire a token manually - the default GITHUB_TOKEN
already has checks: write permission in the common case.

* fix: bump @game-ci/unity-engine-core pin to pick up the results-check ENOENT fix

All matrix jobs on this PR's CI were failing after tests passed with
ENOENT: results-check-summary.hbs - the actual bug (results-check.ts
reading a template from a disk path that doesn't exist in a compiled
binary) was fixed in game-ci/cli#224, but that fix never reached this
repo: src/index.ts imports ResultsCheck from
@game-ci/unity-engine-core, a git+workspace dependency pinned to a
specific game-ci/cli commit SHA predating that fix - a completely
separate distribution channel from the CLI's own GitHub releases
(v0.1.x), which is what earlier verification here actually checked.

Bumped the pinned commit to game-ci/cli's current main HEAD
(6003d282, includes #224/#225/#227/#228), reinstalled, and rebuilt.
Verified: dist/index.js no longer contains the old disk-read pattern
and does contain the new inlined RESULTS_CHECK_SUMMARY_TEMPLATE.

* fix: bump @game-ci/unity-engine-core pin to pick up the explicit-docker-pull fix

game-ci/cli#229 fixes the root cause of this PR's remaining "Test all
modes" Windows failures: docker run's implicit pull folded a 16-minute
partial-cache-miss pull into the same session as Unity's license
activation, causing the license return to fail once the container
finally started. Docker.run now pulls explicitly, before that window
opens.

* fix: remove accidentally-committed stale test result files, gitignore artifacts/

Root-caused the "Test all modes" windows-2022 failures on #310's CI:
all 3 Unity versions failed with real-looking test-content failures
(4/14 passed, 6 failed), but the counts were an EXACT match for
artifacts/{editmode,playmode}-results.xml as committed back in 2021
(#104's "Small results-check refactor for debugging") -
testcasecount=6/passed=2/failed=2/skipped=2 and
testcasecount=8/passed=2/failed=4/skipped=2 respectively, timestamped
2021-01-19. Ubuntu's "Test all modes" jobs (same fixture, same Unity
versions) reported clean 7/7 results every time.

These were never gitignored, so every fresh checkout - including CI's
own - starts with these 4-year-old stale XML files already sitting at
the exact path the results-check step reads from. Ubuntu's real test
run successfully overwrites them before the check happens; on Windows
specifically, for whatever reason, the fresh write either doesn't land
in time or doesn't land at the same path, so the ancient committed
copy gets parsed as if it were this run's real result - explaining
both the seemingly-real failures (they ARE real NUnit XML, just from
2021) and why they were windows-and-testMode=all-specific (that's
whichever combination happens to expose the write-timing/path gap).

Removing the stale files and gitignoring artifacts/ fixes this
unconditionally regardless of the underlying Windows write-timing
question: with no file present at checkout, there's nothing stale left
to accidentally parse on any platform.
