fix(ci): pin third-party actions to full commit SHAs

The account's Actions policy requires a full-length SHA ref. A tag or branch ref is refused at
startup — startup_failure, no jobs, "this workflow graph cannot be shown" — so these workflows
could not run at all. This resolves each ref to the commit it currently points at and records the
ref in a trailing comment, e.g. actions/checkout@<sha> # v4.

dtolnay/rust-toolchain takes its toolchain from the ref itself, so those steps also gained an
explicit with: toolchain: input; without it, a SHA ref would silently lose the channel.

No behaviour is intended to change beyond the pins.

site:docs.github.com GitHub Actions workflow duplicate YAML mapping keys duplicate key parser error

💡 Result:

<search_synthesis>
In GitHub Actions, YAML files must adhere to standard YAML syntax [1][2]. While the official GitHub Actions documentation does not explicitly detail a specific "duplicate key parser error" message, standard YAML parsers—which GitHub uses to process workflow files—typically treat duplicate keys as invalid or ambiguous [1][2]. If a GitHub Actions workflow contains duplicate mapping keys, the workflow will generally fail to parse, resulting in a validation error when you attempt to commit or run the workflow. This is because the YAML specification (which GitHub Actions follows) requires keys within a mapping to be unique. To resolve this issue: 1. Review your workflow YAML file for any keys that appear more than once at the same indentation level (e.g., defining env or steps twice within the same job). 2. Ensure that all job identifiers (jobs.<job_id>) are unique within the jobs object [1][3]. 3. Use a YAML validator or linter to identify the specific line causing the duplication. Note that this behavior is distinct from some other GitHub APIs (such as the Copilot content exclusion API), which may simply overwrite earlier entries with the last occurrence of a duplicate key [4][5]; however, for GitHub Actions workflow files, strict YAML compliance is required, and duplicate keys will cause the workflow to be rejected.

See Understanding GitHub Actions. ## Setting an ID for a job Use `jobs.<job_id>` to give your job a unique identifier. The key `job_id` is a string and its value is a map of the job&`#39`;s configuration data. You must replace `<job_id>` with a string that is unique to the `jobs` object. The `<job_id>` must start with a letter or `_` and contain only alphanumeric characters, `-`, or `_`. ### Example: Creating jobs In this example, two jobs have been created, and their `job_id` values are `my_first_job` and `my_second_job`. ```yaml jobs: my_first_job: name: My first job my_second_job: name: My second job ``` ## Setting a name for a job Use `jobs.<job_id>.name` to set a name for the job, which is displayed in the GitHub UI. ## Defining prerequisite jobs Use `jobs.<job_id>.needs` to identify any jobs that must complete successfully before this job will run. It can be a string or array of strings. If a job fails or is skipped, all jobs that need it are skipped unless the jobs use a conditional expression that causes the job to continue. If a run contains a series of jobs that need each other, a failure or skip applies to all jobs in the dependency chain from the point of failure or skip onwards. If you would like a job to run even if a job it is dependent on did not succeed, use the `always()` conditional expression in `jobs.<job_id>.if`. ### Example: Requiring successful dependent jobs ```yaml jobs: job1: job2: needs: job1 job3: needs: [job1, job2] ``` In this example, `job1` must complete successfully before `job2` begins, and `job3` waits for both `job1` and `job2` to complete. The jobs in this example run sequentially: 1. `job1` 2. `job2` 3. `job3` ### Example: Not requiring successful dependent jobs ```yaml jobs: job1: job2: needs: job1 job3: if: ${{ always() }} needs: [job1, job2] ``` In this example, `job3` uses the `always()` conditional expression so that it always runs after `job1` and `job2` have completed, regardless of whether they were successful. For more information, see Evaluate expressions in workflows and actions. ## Using a matrix to run jobs with different variables To automatically run a job with different combinations of variables, such as operating systems or language versions, define a `matrix` strategy in your workflow. For more information, see Running variations of jobs in a workflow. <title>REST API endpoints for Copilot content exclusion management</title> https://docs.github.com/en/rest/copilot/copilot-content-exclusion-management # REST API endpoints for Copilot content exclusion management Use the REST API to manage Copilot content exclusion rules. > [!NOTE] > Most endpoints use `Authorization: Bearer ` and `Accept: application/vnd.github+json` headers, plus `X-GitHub-Api-Version: 2026-03-10`.

"GitHub Actions" duplicate key with YAML workflow error

💡 Result:

<search_synthesis>
A "duplicate key" error in a GitHub Actions YAML workflow occurs when a key is defined more than once within the same mapping (dictionary) [1][2]. Because GitHub Actions requires unique keys to parse the workflow configuration correctly, the presence of duplicates causes the workflow file to be rejected as invalid [1][3][4]. Common causes and solutions include: 1. Duplicate Job IDs: If you define two jobs with the same identifier (e.g., two jobs named build), the workflow will fail [1]. Ensure every job has a unique ID [1]. 2. Accidental Concatenation: Sometimes, a workflow file may accidentally contain two full workflow definitions concatenated together, resulting in duplicate top-level keys like name, on, or jobs [4]. Review the file to ensure it contains only one complete workflow structure [4]. 3. Case-Insensitivity: Note that some keys in GitHub Actions are treated as case-insensitive [5][6]. For example, defining both version_name and VERSION_NAME within the same matrix mapping will trigger a duplicate key error because the system treats them as the same key [5][6]. 4. Duplicate Triggers or Configuration: Accidentally repeating blocks (such as multiple on: pull_request sections) will cause a failure [3]. Consolidate these into a single block [4]. To prevent and debug these errors: - Use a YAML linter or specialized tools like actionlint, which can detect duplicate keys and other syntax issues before you push your code [5][1][7]. - Carefully review your YAML indentation and structure to ensure keys are not nested incorrectly or repeated [2]. - If you are using a CI/CD pipeline to validate your workflows, ensure it runs a linter that specifically checks for duplicate keys [1][3].

A Missing Required Field (Like `on:` or `jobs:`). It’s tempting to assume a missing top-level key is the culprit. However, the “Invalid workflow file” error is more granular than that. Missing `on:` or `jobs:` will usually result in a more specific error message pointing directly to the missing key. This error typically indicates a problem within a defined section, not the absence of a section itself. While verifying these top-level keys is good practice, don’t spend excessive time on them if you’re seeing this specific message. ... 7. A Simple Typo in a Key Name (Like `job` instead of `jobs`). While typos are common, this error message is often triggered by more subtle issues than a simple misspelling of a top-level key.

Unexpected empty mappings ... Unexpected mapping values ... { }}` ... [Workflow syntax][syntax-doc] defines what keys can be defined in which mapping object. When unknown key is defined, it makes the workflow run fail. actionlint can detect unexpected keys while parsing workflow syntax and report them as an error. Key names are basically case-sensitive (though some specific key names are case-insensitive). This check is useful to catch case-sensitivity mistakes. ## Missing required keys and key duplicates ... Example input: ```yaml on: push jobs: test: strategy: # ERROR: Matrix name is duplicated. These keys are case-insensitive matrix: version_name: [v1, v2] VERSION_NAME: [V1, V2] # ERROR: runs-on is missing steps: - run: echo &`#39`;hello&`#39`; ``` ... ``` test.yaml:3:3: "runs-on" section is missing in ...

Some mappings must include specific keys. For example, job mappings must include `runs-on:` and `steps:`. And duplicate keys are not allowed. In workflow syntax, comparing some keys is **case-insensitive**. For example, the job ID `test` in lower case and the job ID `TEST` in upper case are not able to exist in the same workflow. actionlint checks these missing required keys and duplicate keys while parsing, and reports an error. ## Unexpected empty mappings

Merge the duplicate with mappings.

The dtolnay/rust-toolchain step defines with twice at the same mapping level. GitHub Actions rejects duplicate mapping keys during workflow validation; it does not silently discard one input. Keep both inputs in one mapping.

Proposed fix

         with:
           toolchain: stable
-        with:
-          components: rustfmt, clippy
+          components: rustfmt, clippy
