These workflow files are not valid YAML, so they have never run. Not "ran and failed" — never ran. GitHub Actions rejects the file before creating any job: the run is recorded as failure with no jobs, no log and no check run, and gh pr checks shows no row at all. A red mark with nothing behind it to read.

Cause

A sweep added permission declarations by line position rather than by parsing the document. Three invalid shapes resulted:

A — a mapping indented under a scalar value

permissions: read-all
  actions: read        # read-all is a SCALAR; it cannot take children

read-all already grants everything actions: read would, so the orphaned line is dropped and nothing is lost.

B — injected inside another block

on:
  permissions: contents: read     # two colons, and illegal under `on:` anyway
  push:

C — a literal \n that was never interpreted, gluing the escape's n to the key:

    runs-on: ubuntu-latest
npermissions:                     # "\npermissions:" written literally

Only a text-level writer emitting an uninterpreted escape can produce that.

Verified, not assumed

Every workflow in this repository parses after the change. The repairer refuses to write any file that does not parse and still contain jobs afterwards.

Where a job-level permissions: line was removed, a read-only top-level permissions: remains, so nothing is widened — and if none would remain, the tool reports that rather than inventing one. Guessing a permission set is how you silently over-grant.

Estate context

67 repositories and 100 workflow files are in this state. The most frequently broken file is workflow-linter.yml, in 22 repositories — followed by scorecard.yml (20) and dogfood-gate.yml (13).

The workflow whose job is to lint workflows was itself unparseable, so it never ran, and never caught this or anything else. The check that would have found the damage was destroyed by the same sweep that caused it.

So it cannot recur invisibly

Detection is being added upstream: a strict-YAML check in the governance reusable — hyperpolymath/standards#582. Ordinary validation cannot see this class of fault, because yaml.safe_load silently accepts duplicate keys and only a full parse catches the malformed indentation.

Expect this repository to get louder

Workflows that have been failing silently will now actually run, and some will find real problems that have been invisible for as long as the files have been broken.

🤖 Generated with Claude Code

GitHub Actions rejects an unparseable workflow before creating any job: the
run is `failure` with no jobs, no log and no check run. These files have never
executed once.

All of it traces to sweeps that edited by LINE POSITION rather than by parsing.
The shapes repaired here:

  * A permissions block substituted INTO A QUOTED SHELL STRING, splitting it:

        echo "Add 'permissions:
      contents: read' at workflow level"

    The second line sits at 2-space indent, less than the surrounding block
    scalar, so it terminates the block and YAML tries to parse it. Rejoined.

  * A top-level `permissions:` block dropped INSIDE a job, at column 0 between
    `timeout-minutes` and `steps`. Removed; the job is covered by the
    top-level declaration.

  * TWO top-level `permissions:` blocks. Merged, keeping the widest value for
    each key (write > read > none) — the only choice that cannot remove a
    capability a job already relies on.

  * An embedded interpreter script written at column 0 inside `run: |`,
    ending the block scalar. Re-indented into it. Safe for the program too:
    YAML strips the block-scalar indent when building the string, so the shell
    and Python still receive it at column 0 with relative indentation intact.

  * A `run:` scalar containing ": " inside a quoted string, which YAML reads
    as a mapping. Converted to a block scalar.

VERIFIED: every workflow in this repository parses after the change, and each
repairer refuses to write a file that does not parse and still contain jobs.

Part of an estate-wide repair — 67 repositories, 100 workflow files. The
most frequently broken file was workflow-linter.yml, in 22 repositories: the
workflow whose job is to lint workflows was itself unparseable, so it never
ran and never caught this.

Detection is being added upstream so it cannot recur invisibly:
hyperpolymath/standards#582. Ordinary validation cannot see this class of
fault — yaml.safe_load silently keeps the last duplicate and reports success.

EXPECT THIS REPOSITORY TO GET LOUDER.
