What this changes

Adds a Step 3 subsection to references/safe-refactoring.md, inside the existing Entity Renames section:

Display names are a separate field (Step 3):

entity_id and display name are stored independently, and renaming in the UI writes a user override rather than changing the value the integration supplied. The registry keeps both:

Registry Integration-supplied User override
entity original_name name
device default_name name_by_user

The override takes precedence for as long as it is set. If the integration later reports a corrected name — the device is renamed in its vendor app, a firmware update fixes a typo — the new value lands in the integration-supplied field and never reaches the UI, so the stale override looks like an integration bug to whoever finds it later.

Rename at the source when the source is what is wrong, and reserve the override for names HA itself owns. To annotate without shadowing — marking an entity unused, grouping for a dashboard — use labels, areas, or categories, which live in their own fields and survive a source-side rename. Clearing the override restores the inherited name.

Placed inside the existing section rather than as a new top-level one, so no TOC entries or anchors change.

Why

Entity Renames covers entity_id renames thoroughly — sibling discovery, dashboard reference locations, config-entry and storage-dashboard blind spots — but the display name is a different field with a different failure mode, and it is not mentioned.

The failure is delayed, which is what makes it worth a paragraph. Setting the override is immediate and obviously correct at the time. The cost lands later, when the integration reports a better name and it silently does not appear; at that point the override reads as an integration bug rather than a local setting, and the natural next step is to go debug the integration.

Concretely: an agent asked to make a badly-named entity clearer will set the name, because that is the direct route. The skill currently gives it no reason to consider the source, or to reach for a label instead.

Tests

  • python -m skills_ref.cli validate skills/home-assistant-best-practices/Valid skill
  • No new links or anchors introduced; the subsection sits under an existing heading, so existing anchors and the TOC are untouched.
  • Per CONTRIBUTING step 6, updated the descriptions that route a reader here, since the file now covers a scope they did not imply: the safe-refactoring rows in SKILL.md's reference table and README.md's Skill Contents table, plus the decision-workflow gate at the top of SKILL.md.

Scoped to HA registry behaviour only — no naming conventions or style preferences, per CONTRIBUTING's "no opinionated conventions".

Summary by CodeRabbit

  • Documentation
    • Expanded safe-refactoring guidance to cover display-name overrides in addition to entity renames.
    • Documented how display names differ from entity IDs and how user overrides affect inherited names.
    • Added recommendations for choosing between source renames, overrides, labels, areas, and categories.

The Entity Renames section covers entity_id renames thoroughly — sibling
discovery, dashboard reference locations, config-entry blind spots — but
never mentions that the display name is stored independently, and that
renaming in the UI writes a user override rather than changing the value
the integration supplied.

That gap has a delayed failure mode. Once `name` / `name_by_user` is set it
takes precedence for as long as it exists, so a later corrected name from
the integration — device renamed in its vendor app, firmware typo fixed —
lands in `original_name` / `default_name` and never reaches the UI. The
stale override then reads as an integration bug rather than a local
setting, often months after it was set.

Adds a Step 3 subsection with the field pairs, the mechanism, and the
non-shadowing alternatives (labels, areas, categories). Placed inside the
existing Entity Renames section rather than as a new top-level section, so
no TOC entries or anchors change.

Per CONTRIBUTING step 6, also updates the descriptions that route a reader
to this file, since it now covers a scope they did not imply: the
safe-refactoring rows in SKILL.md's reference table and README.md's Skill
Contents table, and the decision-workflow gate at the top of SKILL.md.

Verified with `skills_ref.cli validate` — skill valid.

… covers display-name changes

- Device registry table: the integration-supplied value lives in the
  entry's `name` field (DeviceInfo `default_name` is a deprecated
  discovery-only default, not the registry field `name_by_user` shadows).
- Step 0 gate in SKILL.md now names display-name changes explicitly so a
  display-name-only rename also routes through safe-refactoring.md.

Verified with `skills_ref.cli validate` — skill valid.

Addressed both review findings in 9d00f5c: the device registry table now shows name as the integration-supplied field (default_name was the deprecated DeviceInfo discovery default, not the registry field), and the Step 0 gate now explicitly includes display-name changes so display-name-only renames also route through safe-refactoring.md.
