# Chrome Web Store release: checklist and changelog

Release-readiness check of the extension built from `dev` at `fc9b820d` on 2026-10-30. The check was read-only: nothing was published, and the live API was used with a few GET requests.
Release-readiness check of the extension built from `dev` at `fc9b820d` on 2026-10-30, with the TikTok content-script row updated on 2026-11-04 (#1601). The check was read-only: nothing was published, and the live API was used with a few GET requests.

## 1. Readiness check (2026-10-30)

| Check | Result | Evidence |
| :--------------------------------------------- | :------------------------ | :-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| Build (`pnpm --filter @repo/extension build`) | Pass | `dist/` holds 11 files, 936 KB. The manifest is MV3, version `2.0.0`. |
| Extension tests, typecheck, lint | Pass | `test-extension-pipeline.ts` passes, including #1302, #1304 and #1326; `eslint --max-warnings 0` is clean. |
| Manifest permissions match `CHROMEWEBSTORE.md` | Pass | `storage` and `sidePanel`; 11 store host patterns (10 stores, TikTok on two hosts) plus `rate.vn` and `www.rate.vn`. The content-script matches equal the store hosts. The pipeline test enforces this (#1231). |
| `review_risk_score: null` shown as no data | Pass | The live lookup returns `null` for a seller with no analysed review, and the side panel shows `reviewRiskNoData` (#1266). |
| `dosafe_risk_score: null` | Fixed in #1465 (PR #1476) | A seller with no DOSafe score answers null from the API and reads "chưa đủ dữ liệu" in the side panel, never "0". |
| Verdict `messageKey` and the locale catalogue | Pass | All 10 server keys (`apps/web/src/server/rate/extension.ts`) map in `VERDICT_MESSAGES`. Every label and explanation exists in vi, en and cs with the right placeholder count. The live lookup returns `genuine_deal` and `fair_market` with their params. |
| Lookup ranking (#1379) | Pass | Live lookup of "Apple iPhone 16 128GB" matches `apple-iphone-16-128gb`, not the 16e. |
| 429 handling | Fixed in #1466 | After a 429 the extension sends no lookup until `Retry-After` (default 60 s, cap 600 s), the panel says how many seconds to wait, and the pill looks the product up again once the wait is over. |
| No locale sent | Pass | The lookup sends platform, URL, title, mode, ids, variant and prices, but no locale. The verdict is rendered from `messageKey` in the extension's language. |
| Version header | Fixed in #1466 | `X-Rate-Extension-Version` reads `chrome.runtime.getManifest().version`. |

Correct the TikTok scope sentence in the store changelog.

The manifest injects the content script on every shop.tiktok.com page, because its match has no path restriction. The script runs on those pages and sends nothing on non-product pages. The changelog says the extension runs only on product pages, which is inaccurate for shop.tiktok.com. State the behavior separately for each host.

state that the extension loads only on product pages on www.tiktok.com, while on

Product pages with /video/ in the query do not get the content script.

Chrome matches exclude_matches against the path and query. For https://www.tiktok.com/@seller/product/123?ref=/video/456, the include https://www.tiktok.com/@*/product/* matches. The exclude https://www.tiktok.com/@*/video/* at apps/extension/manifest.json:61 also matches, because * spans / and the query. The exclude wins, so the script does not run on this product page and no badge appears.

The current patterns cannot keep this product page while excluding video pages whose query contains /product/, such as /@x/video/y?ref=/product/1. Fixing this requires a decision on how injection is filtered. A check inside the content script runs after injection and does not change which pages receive the script.

Add a regression case for a product URL with /video/ in its query to apps/extension/src/test-extension-pipeline.ts. The current injectedOn model fails that case, so the model must change with the fix.

Review comment at @apps/extension/manifest.json at line 61:
The overlapping `exclude_matches` pattern can suppress product-page injection
based on query text, and the manifest patterns alone cannot distinguish the
required cases. Update the injection-filtering mechanism to base the decision on
the URL path, preserving injection on product pages and exclusion on video pages
regardless of query contents; establish a supported mechanism rather than
relying on a check that runs after injection. Add the product URL regression
case to `injectedOn` in `test-extension-pipeline.ts` and update that model to
reflect the fix.

Limit the TikTok content-script scope to the URL pathname.

The https://www.tiktok.com/@*/product/* match also matches profile URLs whose query contains /product/. For example, https://www.tiktok.com/@seller?ref=/product/123 matches, so the content script runs on a profile page outside the product-page scope. WebExtensions match patterns compare the path together with the query string, so query text can satisfy the path component.

The negative URL list in test-extension-pipeline.ts has no profile URL of this form, so the test does not detect the problem. Add that case only after the scope check uses the pathname. Adding it now fails the injectedOn assertion.

The scope check must ignore the query string. A broad exclude_matches entry such as https://www.tiktok.com/@*?*/product/* is not safe. It also excludes the valid product URL https://www.tiktok.com/@shop/product/1?ref=/product/123. Changing the extractor regex does not change injection, because injectedOn reads only the manifest matches and exclude_matches entries.

556 - 565:
Update the TikTok injection scope so eligibility is determined from the URL
pathname, not query text; manifest match and exclude patterns alone cannot
provide this distinction. Use an injection mechanism that can verify the
pathname before injecting, preserve valid product URLs even when their query
contains `/product/`, and add the profile-query URL to the negative cases in the
`injectedOn` tests.
