Registry YAML Sort Policy

The hyperlane-registry CI (and CodeRabbit) reject a PR whose warp route YAML isn't alphabetically sorted on two levels. Every skill that writes or edits a deploy.yaml or config.yaml must satisfy both invariants before showing the file for review or committing, so this is the single source of the rule and the canonical key orders.

This ordering is a lint / CI requirement, not a schema-semantic one — YAML mappings parse identically regardless of key order, so a mis-ordered entry never breaks a deploy or changes behavior (e.g. type after tokenFee is valid); it only fails the PR check. Sort for the lint, not for correctness.

The two invariants

1. Top-level chain entries must be in alphabetical order by chain name. E.g. an arbitrum + base + ethereum route has arbitrum: before base: before ethereum:. When inserting a new chain or restructuring a file, re-sort the top level by chain name — insert at the alphabetical position, never at the top or bottom.
2. Keys within each chain entry must be in strict alphabetical order. When adding a field, insert it at its alphabetical position — never at the top, the bottom, or "after a specific sibling key".

Canonical key orders

These are the alphabetical orderings for the two file types (use them as the visual reference when inserting a key):

• deploy.yaml token entry: decimals, mailbox, name, owner, symbol, token, tokenFee, type. (Additional keys — e.g. hook, interchainSecurityModule, gas, collateralChainName — slot in at their own alphabetical position.)
• config.yaml token block: addressOrDenom, chainName, coinGeckoId, connections, decimals, logoURI, name, standard, symbol, tokenType.

Any key not listed slots in at its own alphabetical position; the lists above are the common cases, not an exhaustive schema.

Verify before review / commit

Before showing the file for review (or committing), confirm both invariants on the final file:

• Top-level chain entries are alphabetical by chain name.
• Within each chain's block, keys are alphabetical (a visual scan against the canonical order above is enough; for stronger confidence pipe the file through yq and compare against a sorted rendering).

If either invariant fails, fix the file first — CI / CodeRabbit will otherwise block the PR.
