Session Handoff [auto-1886]: Distinguish ./ From $/ Resolution in the Pin Rule's Prose (#1886)

[ptr727]

Next steps, in priority order

1. Fix A Local ./ Reference in a Called Reusable Workflow Does Not Run at the Workflow Commit #1886. scripts/README.md's sha-pin bullet says local (./) and self-repository ($/) references both "run at the workflow commit". Distinguish them: a $/ reference resolves at the containing workflow file's commit, while a ./ reference resolves against whatever the job checked out, which for a reusable workflow called from another repository is the caller's checkout. Check WORKFLOW.md's test-methodology trace paragraph (the sentence "A local (./) or self-repository ($/) call carries no pin of its own and runs at the workflow commit") for the same gap and correct it the same way. Verify the claim against docs/reusable-workflows.md and the definition of $/ that State the Pin Comment as the Release Tag and Define $/ #1885 added before editing. Done looks like: both surfaces state the distinction, the prose gates pass, and a pull request into develop carrying Closes on promotion: #1886 has merged.

External blockers

None known.

Internal dependencies

None. WORKFLOW.md is carried canonical content, so the wording must hold for every carrier, not only the hub.

State

No branch, worktree, or pull request exists for this lane yet. #1885, which introduced the $/ definition this issue builds on, is merged to develop and not yet promoted. Re-derive develop's tip and the open pull requests before starting.

The parked decision queue

None for this lane.

What the last round did

A picker created this lane from the open backlog. Nothing has been worked.

What not to repeat

Nothing yet.

New learnings

None.

Lane closed out

• Merged: Distinguish ./ From $/ Resolution in the Pin Rule's Prose #1888 into develop as 22c6a8b. It carries Closes on promotion: #1886, so A Local ./ Reference in a Called Reusable Workflow Does Not Run at the Workflow Commit #1886 stays open until the develop -> main promotion.
• Fixed: A Local ./ Reference in a Called Reusable Workflow Does Not Run at the Workflow Commit #1886. scripts/README.md's sha-pin bullet and WORKFLOW.md's test-methodology trace paragraph now distinguish a $/ call or job-level ./ reusable-workflow call, which resolves at the calling workflow file's commit, from a ./ action reference, which resolves against whatever the job checked out. The check_sha_pin docstring matches, and the generated skill copies are regenerated.
• Filed: Tighten sha-pin's Local-Ref Skip: Bare .github/ and Quoted Refs #1889, a pre-existing gap in check_sha_pin's skip list (a bare .github/ ref is skipped unvalidated, and a quoted local ref is reported as having no ref). No lesson issue was filed.
• Review: four local strict review passes, the findings fixed in the branch. Copilot raised one thread, fixed and resolved. The worktree and both branch copies are deleted.

This auto-* lane held one issue, so it closes with no successor.
