backlog(B-0087 P1): github-settings-drift.yml broken since PR #45 — invalid GHA permission

[AceHack]

Summary

The Workflow Null-Result Audit Signal class memory (PR #685, Amara naming) just paid out concretely. Applied the six-question diagnostic to the budget-snapshot-flagged failing workflow — caught a real factory-hygiene bug:

$ actionlint .github/workflows/github-settings-drift.yml
Line 45: unknown permission scope "administration"

administration is NOT a valid GITHUB_TOKEN permission scope. Workflow has been broken for its entire history on LFG main (PR #45 introduced; PR #375 didn't fix). GHA returns "workflow file issue" at startup → all runs fail → drift detector silently inactive for days+.

What this PR adds

One per-row backlog file at docs/backlog/P1/B-0087-*.md (164 lines) asking maintainer to pick A (replace permission with valid scopes) / B (PAT secret) / C (GitHub App).

Why this is substrate-grade

Closes the discipline-application loop:

1. Class memorialized in PR memory + backlog: TypeScript-default + 3 Amara-named classes + B-0086 port row #685 (Amara naming)
2. Audit applied this tick
3. Real factory-hygiene bug found
4. Backlog row filed (visibility-constraint prevents autonomous fix)

This is the "class pays rent immediately, not just being named" pattern — same shape Amara called out in the Chronological Insertion Polarity Error case.

Test plan

• Per-row file validates against schema in tools/backlog/README.md
• No code-surface changes (substrate only)
• actionlint output verified (verbatim error captured in row body)
• Pushed for visibility, not auto-merged — maintainer-call required

Pull request overview

Adds a P1 backlog row documenting that .github/workflows/github-settings-drift.yml is currently invalid due to an unsupported GITHUB_TOKEN permission scope (administration: read), causing the drift-detector workflow to fail at startup and provide no signal.

Changes:

• Add B-0087 per-row backlog file describing the invalid permission, impact (workflow never runs), and suggested remediation options (valid scopes vs PAT vs GitHub App).
• Capture the actionlint diagnostic output and define acceptance criteria for restoring the drift detector’s signal.

The referenced memory file memory/feedback_incomplete_source_set_regeneration_hazard_and_workflow_null_result_audit_amara_2026_04_28.md does not exist in this repo (so this link will be broken after merge). Either include the memory file in this PR, or change the reference to an existing in-repo artifact (or the PR/commit where it was introduced).

In the failure-mode bullets, the gh api /repos/.../rulesets call is attributed to tools/hygiene/check-github-settings-drift.sh, but that script only diffs expected vs a temp snapshot and delegates API calls to tools/hygiene/snapshot-github-settings.sh. Updating this description will make the debugging path accurate (permissions/errors originate in the snapshot script).

Suggested change

	(`tools/hygiene/check-github-settings-drift.sh`) calls
	`gh api /repos/.../rulesets` and similar admin endpoints,
	which return 403.
	(`tools/hygiene/check-github-settings-drift.sh`) delegates
	snapshot collection to

	those calls return 403.

This bullet claims the drift detector script was run locally “per the workflow header comment”, but .github/workflows/github-settings-drift.yml doesn’t mention that, and the scripts’ headers don’t document a specific prior run. Consider rephrasing to a verifiable statement (e.g., that the scripts are safe to run locally with sufficient credentials) or cite the exact in-repo comment/source that supports the claim.

Suggested change

	- The drift detector **script** itself works correctly when
	run with a sufficient PAT (Aaron has run it locally per the
	workflow header comment).
	- The drift detector **script** is intended to work when run
	locally with a sufficiently privileged PAT; the documented
	failure here is the workflow's invalid `GITHUB_TOKEN`
	permission/request path, not the script logic itself.
