home-assistant/frontend: technical due diligence, read from its repository
What Borehole read in home-assistant/frontend's code and history at 2c6cf8e: its licence, security advisories, releases, review practice, tests, dependencies and operations. Every finding cites the file and line it rests on. The full report also covers the team and asks the questions the code cannot answer.

Architecture & Codebase — including AI provenance
strongsrc/data/energy.ts is 2,585 lines, 22× this codebase's median file
adequateThe median source file here is 116 lines. 44 files exceed 1,160 lines, the largest being 2,585. Size is not a defect on its own — some problems genuinely live in one place — but these are where merge conflicts, review fatigue and single-owner knowledge concentrate, and they are the first thing that slows an inheriting engineer down.
src/data/energy.ts:1 — 2,585 lines (22× median) |
src/fake_data/demo_services.ts:1 — 2,361 lines (20× median) |
src/components/chart/ha-chart-base.ts:1 — 2,349 lines (20× median) |
src/resources/jinja_ha_completions.ts:1 — 2,294 lines (19× median) |
src/components/data-table/ha-data-table.ts:1 — 2,190 lines (18× median) |
Engineering Process & SDLC Maturity
strongTests are retried until they pass
adequateThe suite is configured to retry failing tests (test/e2e/playwright.app.config.ts). A retry turns a flaky test green without saying why it failed, so a green build means the tests passed eventually. Ask how many retries a typical run needs, and which tests need them.
test/e2e/playwright.app.config.ts:14 — test retry |
Product & Engineering Maturity
adequate94 direct dependencies in a single manifest
adequatepackage.json declares 94 direct dependencies. Each one is a maintenance obligation, a supply-chain surface and a potential licence question that transfers with the asset. The count says nothing about whether any given dependency was a good choice; it says how many such choices a buyer inherits.
package.json — 94 declared |
6% of bug fixes add or change a test
adequateOf 1858 fixes in the last 24 months, 118 touched a test. A fix without the test that would have caught the bug can quietly come back, and the suite never learns from what went wrong.
| 118 of 1858 |
Releases are cut from another branch than the one surveyed
adequateThe newest release, 20261028.3, is not on the branch this survey read; the newest release on it is 20261028.0. The shipped product may differ from what this report describes. Survey the release branch too.

Security & Reliability Posture
strong19 locked dependencies have published vulnerabilities, 16 high or critical
adequate19 of 1,676 locked dependencies match 39 published advisories in OSV, 16 of them rated high or critical. A lockfile says which version is installed, not whether the flawed code is reachable from this product, so each needs a look. Most are fixed by an upgrade, and the advisory names the version. None of the high or critical ones is in what the product ships: they are development dependencies.
pnpm-lock.yaml — shell-quote 1.10.0: GHSA-pqg4-j6r4-53mv (critical), fixed in 1.11.0; a development dependency |
pnpm-lock.yaml — brace-expansion 1.1.18: GHSA-6j4f-fj2g-mc7p (high), fixed in 1.1.19; a development dependency |
pnpm-lock.yaml — brace-expansion 2.1.4: GHSA-6j4f-fj2g-mc7p (high), fixed in 2.1.5; a development dependency |
Observability & Operations
not assessableNot rated: only 5 of 16 checks could reach a conclusion here; the rest do not apply to this repository or could not read it.
