+
+# Weekly cadence for evidence-based LFG burn tracking. Runs
+# tools/budget/snapshot-burn.sh, captures the resulting JSONL row,
+# opens a PR (per the AceHack-first UPSTREAM-RHYTHM rhythm) with the
+# snapshot included, and arms auto-merge so the row lands without
+# human intervention. Closes task #297 (cadence half of the
+# evidence-based-budgeting work; tooling was task #285, baseline
+# snapshot was task #287).
+#
+# Why weekly: docs/budget-history/README.md says "On a cadenced
+# schedule (weekly) — catches drift when no PRs are merging." Weekly
+# is the right balance for a small project — daily produces too many
+# rows for the burn pattern to be informative; monthly is too coarse
+# for the Stage-1-blocker decision the snapshots were originally
+# designed to gate.
+#
+# Why off-the-hour: GHA cron thundering-herd avoidance per
+# .github/workflows/github-settings-drift.yml convention. Sunday is
+# chosen over weekdays so the snapshot isn't competing with PR
+# cadence for runner minutes.
+#
+# Security note (safe-pattern compliance per
+# https://github.blog/security/vulnerability-research/how-to-catch-github-actions-workflow-injections-before-attackers-do/
+# ): this workflow consumes only first-party trusted context —
+# secrets.GITHUB_TOKEN, github.repository, github.run_id. Every
+# expression value is passed via env: into run blocks and quoted
+# there as "$VAR"; no expressions are interpolated directly inside
+# run-block scripts. The workflow_dispatch `note` input is also
+# routed via env: + quoted to neutralise potentially-malicious
+# content if an attacker with dispatch permissions tries injection.
+#
+# Scope coverage limits per docs/budget-history/README.md:
+# snapshot-burn.sh works without admin:org but captures the
+# scope_coverage block honestly. If the human maintainer later runs
+# `gh auth refresh -s admin:org` the snapshots get richer
+# automatically (Actions billing / Packages / shared-storage).
+#
+# AgencySignature v1 attribution (per the post-ferry-7 convention):
+# this workflow's commits identify themselves as the
+# budget-cadence-workflow agent running on GitHub Actions. The
+# Human-Review-Evidence trailer is "signed-policy" because the
+# cadence is authorized by docs/budget-history/README.md +
+# the maintainer's 2026-04-22 standing direction for evidence-based
+# budgeting.
+#
+# Auto-merge limitation (Codex review #25 P1): events triggered by
+# secrets.GITHUB_TOKEN do not fire downstream workflow runs (GitHub's
+# anti-infinite-loop guard). That means a PR opened by this workflow
+# would never accumulate the required-status-check runs that
+# auto-merge needs to fire on, and `gh pr merge --auto` would sit
+# in a dead-end. Until a PAT secret is configured, this workflow
+# opens the snapshot PR and leaves it for the next human-or-agent
+# pass through the queue to merge — explicit-no-auto-merge over
+# silent-stall is the operational call.
