Give CI its jobs back, and stop a restore ack muting every restart - #482
Conversation
`runner.temp` in workflow-level `env` is not a warning and not one failing job: GitHub rejects the whole file. The run reports failure with ZERO jobs, which reads like an outage rather than a typo, and every gate this repo has silently stops existing. That is what my own previous commit did to master. `github.workspace` is available there and still keeps the target directory off the 7.9G tmpfs, which was the point of moving it. The audit exists because nothing else could have caught this: the file is valid YAML, so the yaml parse I ran passed, and the breakage is only visible once GitHub evaluates contexts. It checks the one thing that is cheap to check and expensive to miss -- a job-scoped context used above `jobs:` -- and it fails on exactly the line that broke, with the consequence spelled out. Prove-failed by reinstating `runner.temp`. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Aimux-Pre-Commit: a7ef910
Twenty agents went offline after a restart and aimux never asked whether to restore them. The snapshot was intact and the boot gate was open; the offer was being deliberately suppressed by an acknowledgement from the day before. A snapshot's id changes only when the SET of agents changes, so the same agents killed a second time carry the same id as the first. The ack was keyed on that id alone, so accepting one offer muted every restart that followed -- permanently, for that set of agents. On this machine it had muted five projects at once. The prompt gate beside it already re-seeds on every daemon boot, which is exactly the unit of "a new occasion". The ack now carries the same stamp and is compared against it, so one made in a previous boot is spent rather than eternal. An ack with no stamp -- every ack written before this -- is treated as spent too: an extra prompt costs a keystroke, and the alternative is what left the user with no prompt at all. The test drives the ack file rather than the restore route, because the route also writes a retry offer when a restore fails and that short-circuits the derive before it ever reads the acknowledgement. That is also why this went unnoticed: the one path a test would naturally take never reaches the check. Gate prove-failed with the mutation verified first: making the acknowledgement permanent again fails the second-restart case.

## Defining environment variables for a single workflow
To set a custom environment variable for a single workflow, you can define it using the `env` key in the workflow file. The scope of a custom variable set by this method is limited to the element in which it is defined. You can define variables that are scoped for:
* The entire workflow, by using `env` at the top level of the workflow file.
* The contents of a job within a workflow, by using `jobs.<job_id>.env`.
* A specific step within a job, by using `jobs.<job_id>.steps[*].env`.

<excerpt>citeturn0search1 [wordlim: 200] Crawled: last week; {% data reusables.actions.expression-syntax-if %} For more information, see AUTOTITLE. ... if: {% raw %}${{ github.event_name == 'pull_request' && github.event.action == 'unassigned' }}{% endraw %} ... Instead, consider setting secrets as job-level environment variables, then referencing the environment variables to conditionally run steps in the job. ... You can also set variables for the entire workflow or a job. ... {% data reusables.repositories.actions-env-var-note %}
Unlike the Docker `ENTRYPOINT` instruction which has a shell and exec form, `entrypoint` keyword accepts only a single string defining the executable to be run.
### Example of `jobs.<job_id>.steps[*].with.entrypoint`
steps:
- name: Run a custom command
uses: octo-org/action-name@main
with:
entrypoint: /a/different/executable
The `entrypoint` keyword is meant to be used with Docker container actions, but you can also use it with JavaScript actions that don't define any inputs.
## `jobs.<job_id>.steps[*].env`
Sets variables for steps to use in the runner environment. You can also set variables for the entire workflow or a job. For more information, see `env` and `jobs.<job_id>.env`.
{% data reusables.repositories.actions-env-var-note %}
Public actions may specify expected variables in the README file. If you are setting a secret or sensitive value, such as a password or token, you must set secrets using the `secrets` context. For more information, see AUTOTITLE.
### Example of `jobs.<job_id>.steps[*].env`
{% raw %}
steps:
- name: My first action
env:
GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
FIRST_NAME: Mona
LAST_NAME: Octocat
{% endraw %}
## `jobs.<job_id>.steps[*].continue-on-error`
Prevents a job from failing when a step fails. Set to `true` to allow a job to pass when this step fails.
## `jobs.<job_id>.steps[*].timeout-minutes`
The maximum number of minutes to run the step before killing the process. Maximum: 360 for both {% data variables.product.github %}-hosted and self-hosted runners.
Fractional values are not supported. `timeout-minutes` must be a positive integer.
{% ifversion actions-nga %}
## `jobs.<job_id>.steps[*].background`
Runs a step asynchronously so the job continues to the next step without waiting for it to finish. Use `background: true` for long-running processes, such as databases, servers, or monitoring tasks, that need to run alongside other steps. You synchronize with background steps later using `wait` or `wait-all` or stop them with `cancel`.

<title>Workflow commands for GitHub Actions - GitHub Docs</title>
<location>https://docs.github.com/en/actions/writing-workflows/choosing-what-your-workflow-does/workflow-commands-for-github-actions?tool=powershell</location>
<excerpt>citeturn0search2 [wordlim: 200] Crawled: 1.3 years ago; To use environment variables in a GitHub Action, you create or modify `.env` files using specific GitHub Actions commands. ... You can make an environment variable available to any subsequent steps in a workflow job by defining or updating the environment variable and writing this to the `GITHUB_ENV` environment file. ... For multiline strings, you may use a delimiter with the following syntax.
YAML
`steps:
- name: Store build timestamp
run: echo "BUILD_TIME=$(date +'%T')" >> $GITHUB_ENV
- name: Deploy using stored timestamp
run: echo "Deploying at $BUILD_TIME"
`
Note
PowerShell versions 5.1 and below (`shell: powershell`) do not use UTF-8 by default, so you must specify the UTF-8 encoding. For example:
YAML
`jobs:
legacy-powershell-example:
runs-on: windows-latest
steps:
- shell: powershell
run: |
"mypath" | Out-File -FilePath $env:GITHUB_PATH -Encoding utf8 -Append
`
PowerShell Core versions 6 and higher (`shell: pwsh`) use UTF-8 by default. For example:
YAML
`jobs:
powershell-core-example:
runs-on: windows-latest
steps:
- shell: pwsh
run: |
"mypath" >> $env:GITHUB_PATH
`
## Setting an environment variable
Note
To avoid issues, it's good practice to treat environment variables as case sensitive, irrespective of the behavior of the operating system and shell you are using.
Bash
`echo "{environment_variable_name}={value}" >> "$GITHUB_ENV"
`
* Using PowerShell version 6 and higher:
PowerShell
`"{environment_variable_name}={value}" >> $env:GITHUB_ENV
`
* Using PowerShell version 5.1 and below:
PowerShell
`"{environment_variable_name}={value}" | Out-File -FilePath $env:GITHUB_ENV -Encoding utf8 -Append
`
You can make an environment variable available to any subsequent steps in a workflow job by defining or updating the environment variable and writing this to the `GITHUB_ENV` environment file. The step that creates or updates the environment variable does not have access to the new value, but all subsequent steps in a job will have access.
You can't overwrite the value of the default environment variables named `GITHUB_*` and `RUNNER_*`. Currently you can overwrite the value of the `CI` variable. However, it's not guaranteed that this will always be possible. For more information about the default environment variables, see Store information in variables.

<location>https://docs.github.com/en/enterprise-server%403.22/actions/reference/workflows-and-actions/workflow-syntax</location>
<excerpt>citeturn0search3 [wordlim: 200] Crawled: yesterday; When you use expressions in an `if` conditional, you can, optionally, omit the `${{ }}` expression syntax because GitHub Actions automatically evaluates the `if` conditional as an expression. ... Allowed expression contexts: `github`, `inputs`, `vars`, `needs`, `strategy`, `matrix`, `job`, `runner`, `env`, and `steps`. ... * Jobs or workflow runs in the same concurrency group are processed in first-in-first-out (FIFO) order according to the time each one started waiting on the concurrency group, not the time each workflow was dispatched. ... The default behavior of GitHub Actions is to allow multiple jobs or workflow runs to run concurrently.
For more information, see `env` and `jobs.<job_id>.steps[*].env`.
When more than one environment variable is defined with the same name, GitHub uses the most specific variable. For example, an environment variable defined in a step will override job and workflow environment variables with the same name, while the step executes. An environment variable defined for a job will override a workflow variable with the same name, while the job executes.
### Example of `jobs.<job_id>.env`
`jobs:
job1:
env:
FIRST_NAME: Mona
`
## `jobs.<job_id>.defaults`
Use `jobs.<job_id>.defaults` to create a `map` of default settings that will apply to all steps in the job. You can also set default settings for the entire workflow. For more information, see `defaults`.
When more than one default setting is defined with the same name, GitHub uses the most specific default setting. For example, a default setting defined in a job will override a default setting that has the same name defined in a workflow.
## `jobs.<job_id>.defaults.run`
Use `jobs.<job_id>.defaults.run` to provide default `shell` and `working-directory` to all `run` steps in the job.
You can provide default `shell` and `working-directory` options for all `run` steps in a job. You can also set default settings for `run` for the entire workflow. For more information, see `defaults.run`.
These can be overridden at the `jobs.<job_id>.defaults.run` and `jobs.<job_id>.steps[*].run` levels.
When more than one default setting is defined with the same name, GitHub uses the most specific default setting. For example, a default setting defined in a job will override a default setting that has the same name defined in a workflow.

Two failures that only became visible once the Linux job could finish a full suite again. It had been dying three minutes in for days, so nothing it would have caught was being caught. The stream-surface contract records the periodic task list, and #481 added `backend-session-id-capture` without re-recording it. This is the third time a new periodic task has broken this fixture, and the reason is always the same: it is a serial-lane target, `yarn verify` does not run it, and the scoped run covering the change does not touch it. Regenerated through the fixture's own record mode rather than hand-edited. The second is mine from an hour ago. `Path::ancestors` is lexical, so `<workspace>/../aimux-cargo-target-ci` leaves the checkout itself an ancestor of the target directory -- and the runtime version is resolved by walking the executable's ancestors for a package.json. The tests found the repo's 0.1.70 instead of the 9.8.7-test they planted, and two entrypoint tests failed on it. A sibling of the workspace has the same disk and no traversal. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Aimux-Pre-Commit: f90578d
Two unrelated fixes, both for things I broke or found while looking at the
other.
CI has no jobs on master right now
My previous commit put
runner.tempin workflow-levelenv. That context isonly available once a job is running, and using it above
jobs:is not awarning and not one failing job — GitHub rejects the whole file. The run
reports failure with zero jobs, which reads like an outage rather than a typo,
and every gate this repo relies on silently stops existing.
github.workspaceis valid there and still keeps the target directory off the7.9G tmpfs, which was the point of the original move.
The audit exists because nothing I ran could have caught it: the file is valid
YAML, so the parse passed, and the breakage only appears once GitHub evaluates
contexts. It checks the one thing cheap to check and expensive to miss — a
job-scoped context above
jobs:— and fails on exactly the offending line withthe consequence spelled out. Prove-failed by reinstating
runner.temp.Twenty agents went offline and aimux never asked to restore them
The snapshot was intact (20 sessions, rewritten right after the restart) and
the boot gate was open. The offer was being deliberately suppressed by an
acknowledgement from the previous day:
A snapshot's id changes only when the set of agents changes
(
same_restore_session_ids), so the same agents killed a second time carry thesame id as the first. The ack was keyed on that id alone, so one accepted offer
muted every restart that followed, permanently, for that set of agents. On this
machine it had muted five projects at once — tealstreet-next (20 agents),
sblr (8), tealstreet-mobile (5), jiten (2), thegrand (2).
The asymmetry is the bug: the prompt gate beside it already re-seeds on every
daemon boot, which is exactly the unit of "a new occasion", while the ack was
eternal — and the ack wins. The ack now carries the same stamp and is compared
against it. An ack with no stamp (every one written before this) is treated as
spent: an extra prompt costs a keystroke, and the alternative is what left the
user with no prompt at all.
Worth noting why this survived: the test that would naturally cover it drives
the restore route, and that route writes a retry offer when a restore fails,
which short-circuits the derive before it ever reads the acknowledgement. The
new test drives the ack file directly for that reason.
This also explains an earlier report in the same session — "I hit restore and
it doesn't work" and "I wasn't even asked" are the same bug: the failed restore
wrote the ack that muted everything after it.
Stale acks on the affected machine were moved aside separately, since no code
change can un-mute an ack already written.
