ci: reproduce the Mirror#4128 Unity abort message end to end - #294
Conversation
When Unity aborts batchmode, Docker.run passes the reason from stdout and then appended `docker run`'s own stderr under an "Original error:" heading. That stderr opens with the benign pre-pull "Unable to find image ... locally" status line, so the message read as an editor failing to load a version and buried the actual cause two lines above it: Unity aborted before completing: Scripts have compiler errors. ... Original error: Unable to find image 'unityci/editor:...' locally Two Mirror maintainers read it exactly that way on Mirror#4128 - they went looking for a 6000.3.23f1 problem while "Scripts have compiler errors." sat in the same message. System.run already streams that stderr live, so repeating it loses nothing. describe() now takes originalMessage as optional and omits the section when the caller has nothing to add. HostRunner keeps passing it: on its --silent path the streamed copy does not exist, so the quoted text is the only one. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
Two defects in the release-download smoke tests, both hit live on PR #293: The macOS job 403'd on api.github.com while the ubuntu job passed beside it, running the same install.sh against the same endpoint in the same minute. install.sh resolves "latest" through the API and authenticates only when handed a token - unauthenticated is 60 requests/hour per IP, and Actions runners share IPs across unrelated repos and orgs. The script was written to be given one, and says so in its own comment; the workflow never passed it. Both smoke steps, and the root-wrapper steps that default to "latest" and hit the same call, now pass GH_TOKEN - the pattern already used throughout orchestrator-integrity.yml. install.sh treats an empty token as no token, so a fork PR (no secrets, read-only github.token) degrades to today's behaviour rather than failing. The retry loop reported every failure the same way - "likely the latest release's binaries are still uploading". A 403 rate limit is not that, and re-running the identical unauthenticated request 30 seconds later cannot clear it, so it spent all five attempts and 2.5 minutes asserting a cause it had no way to know. That is the same misdiagnosis this branch's Unity abort message fix exists to remove: point at the error that actually occurred instead of substituting a guess for it. Verified end-to-end: GH_TOKEN=... bash scripts/install.sh latest <dir> resolves v0.1.69, downloads, and checksum-verifies. actionlint clean. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
A container aborts Unity, docker leads its own stderr with the benign "Unable to find image '...' locally" pre-pull notice, and the CLI's final error used to append that stderr under an "Original error:" heading. The message then read as an editor failing to load a Unity version, while Unity's real reason - a genuine script compile error - sat two lines above it (#288). #293 fixed the message and src/model/docker.test.ts asserts it, but that test hard-codes BOTH streams onto its fake error, so it stays green if Docker.run reads the wrong stream or System.run folds them together. That plumbing is precisely what broke, and nothing in CI ran a real `docker run` through it. This adds that, and grades what the user is actually shown. - New unity-abort-message job: an aborting-editor stub (no Unity, no licence, no multi-GB pull), driven through both CLI routes because they reach stdout differently - build.sh passes `-logfile /dev/stdout`, while test.sh writes the log to a file and cats it after capturing the exit code. Both graded by scripts/assert-unity-abort-message.sh. - Wired into smoke-gate.needs, so a failure there actually fails the gate. - scripts/test-assert-unity-abort-message.sh drives the grader in both directions against hand-written logs - including the pre-#293 message it exists to reject - because its two "must not contain" assertions can only ever pass vacuously on a run that died early. - A stream-split case in system.integration.test.ts, against a real child process rather than the mocked System.run. - A comment pinning the `silent` coupling Docker.run's catch block rests on ("System.run has already streamed it live above"), which holds only while options.silent stays falsy. No behaviour change. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>

Do not pass the private token to pull-request smoke tests.
A same-repository pull request can receive GIT_PRIVATE_TOKEN. The checked-out installer reads GH_TOKEN, so modified pull-request code can access the repository secret. Fork pull requests do not receive repository secrets, but that does not protect same-repository pull requests. Use github.token for pull requests and declare contents: read for these jobs.

Not changed here. This asks for a permission change (contents: read on both install smoke-test jobs) plus new token-resolution semantics on four pre-existing GH_TOKEN lines - none of them in this PR's diff, and the current shape is deliberate: the comment above line 212 documents why the fallback degrades on fork PRs, and changing which token authenticates alters the rate-limit behaviour that comment exists to fix. Changing a workflow's token/permission posture is a maintainer decision, so I have surfaced it rather than folded it into a reproduction PR.

@frostebite, the finding remains applicable to this PR.
The diff adds this GH_TOKEN assignment at Line 213. It introduces the GIT_PRIVATE_TOKEN fallback into a pull_request workflow step. A same-repository pull request can modify the checked-out installer and read that token.
The rate-limit rationale is valid. It does not require exposing GIT_PRIVATE_TOKEN to pull-request code. This token-selection and permission decision can be deferred, but it should be tracked as a follow-up security change. Would you like me to open a GitHub issue for it?

Correction first: you are right and my previous reply was wrong - all four GH_TOKEN lines are added by this PR (5fdab58, which is riding in this branch), so they are in the diff. I had checked the wrong comparison.
I am still not making the change here, and the reason is authority rather than disagreement: adding job-level permissions: blocks and changing which credential authenticates is a permissions/config change, and I will not make one unilaterally on a review bot's request. It is escalated to the maintainer.
Two things I verified for their decision: the secrets.GIT_PRIVATE_TOKEN || github.token fallback is this repo's existing convention (roughly 50 uses across orchestrator-integrity.yml and orchestrator-integration.yml, the latter already invoked by tests.yml with secrets: inherit on pull_request), so that secret already reaches PR-triggered jobs independently of these four lines; and tests.yml declares no permissions: block at all, so the suggestion is a wider workflow change than it appears. Whether to drop the PAT fallback, and whether a tracking issue is worth opening, are theirs to decide.

@frostebite, thank you for the correction and for escalating the permissions decision.
The finding remains open. This PR adds the four GH_TOKEN assignments, and a same-repository pull request can modify the checked-out installer before it reads GH_TOKEN.
The existing secrets: inherit use is relevant to the wider workflow security posture. It does not remove the new exposure from these install smoke-test steps. A maintainer can decide whether to change this PR or track the repository-wide credential policy separately.

Declare UNITY_VERSION through each step's env rather than interpolating the
workflow_dispatch input into the script body, where ${{ }} expands into shell
source before bash sees it. Clean the grader's temp file from an EXIT trap so
an interrupt cannot leave it behind.
