Conversation
…and deep-merge rule Document the central-config branch governance on production (2 approvals, Mergify-only merge-gate bypass, required validate check), replace the audit-log paste evidence with blob-SHA hash verification, and explain how the Global YAML deep-merges into per-repo codecov.yml (informational pin). 🤖 Generated by [robots](https://vyos.io)

Review comments at @AGENTS.md:
- Line 19: Clarify that the dashboard-edit prohibition applies to ad hoc edits,
while permitting only the documented, verified post-merge paste. In AGENTS.md
lines 19-19, narrow the prohibition accordingly; in README.md lines 24-26,
identify the pinned post-merge paste as the sole permitted dashboard edit.

# Repo context for AI assistants
## Change protocol
1. PRs only. No direct dashboard edits. This repo carries the enterprise governance tier
`central-config`: merges to `production` need 2 approving reviews (stale approvals are
dismissed on push), the only bypass on that merge gate is Mergify's PR merge path (no
human bypass), and the per-repo ruleset `production-required-checks` makes `validate`
required. Plan changes so two reviewers are available.

## Change protocol
4. Verify the paste by content hash — the Codecov UI exposes no audit history for the
account YAML. Capture the pre-paste editor content (rollback pre-image), paste via
the clipboard (never type it), reload, copy the editor content back, and check that
`git hash-object` of the copy equals the `codecov.yml` blob SHA. Fetch the payload and
the blob SHA from one `production` commit SHA resolved up front, not from the moving
`production` ref.
Record source commit SHA, blob SHA, paste timestamp, pre-state, and the result in the
change ticket. Full steps: README.md "Paste protocol (operator)".

29-30: 📐 Maintainability & Code QualityCodecov’s documentation says Global YAML changes are stored in history, but it does not establish whether the current
vyosaccount UI shows prior versions, provides rollback, or exposes audit details. The available evidence cannot determine whether “no audit history” is accurate or whether the pre-paste snapshot is needed as the rollback record.
…load Narrow the dashboard rule to the single allowed change (pasting the merged, pinned production payload) and make AGENTS step 3 fetch payload.yml at one resolved commit SHA, matching the README paste protocol. 🤖 Generated by [robots](https://vyos.io)
