# apply-workflow-pins — re-point consumer repositories at the current standards
# reusable-workflow SHA, on a cadence.
#
# WHY A SCHEDULED APPLIER AND NOT A SWEEP (owner ruling STD-R-3):
# A fix landed in `standards` does not reach its callers. Measured 2026-09-15,
# 28 of 29 live remote callers are SHA-pinned and exactly one tracks `@main`.
# A pinned caller keeps consuming the broken commit until something re-points
# it. A sweep does that once and then rots; an applier converges and keeps
# converging, which is what "the estate stays fixed" actually requires.
#
# DEFAULT IS AUDIT. The scheduled run writes nothing unless `mode: fix` is
# chosen explicitly via workflow_dispatch, because the first thing this needs to
# produce is an honest census — how many repos are BEHIND, DEAD-REF or ILLEGAL —
# and a census is evidence only while nothing is mutating underneath it.

# a DEDICATED App for this applier, explicitly NOT OikosBot. Owner ruling
# STD-R-3 / R-14 (2026-09-15). OikosBot is named as a BYPASS ACTOR in the

# identity that may bypass the rules, it would be permanently exempt from
# the rules it exists to uphold. Separation of duties, not style.

# The App needs `contents: write` and `pull_requests: write`, and must be

# and carries its own rate limit, so `owner:` is required — without it the

Select the installation token for each owner.

tok-user is the only token passed to APP_USER and GH_TOKEN. tok-org is never consumed. The applier iterates over OWNERS, but all GitHub CLI calls use the process-wide GH_TOKEN; it has no per-owner token selection.

The workflow states that an installation token is scoped to one owner. If tok-user is present and tok-org fails, the gate still passes and the applier can fail to read or write metadatastician repositories with the hyperpolymath token. Audit mode can also fall back to GITHUB_TOKEN, but tok-org remains unused.

Run each owner with its matching token. If fix mode includes both owners, require both tokens before enumeration.

only still-valid issues, skip the rest with a brief reason, keep changes
minimal, and validate.

In @.github/workflows/apply-workflow-pins.yml at line 97, Update the owner
iteration and GitHub CLI authentication in the workflow so each owner uses its
matching installation token, consuming both tok-user and tok-org instead of a
process-wide GH_TOKEN. In fix mode, validate that every token required by the
selected owners is available before repository enumeration; preserve the
documented audit fallback only where applicable.

After applying the fix, consider running `coderabbit review --agent` for local
