feat(telemetry): anonymous install and update counts - #599
Merged
Merged
Conversation
One event when an install first runs and one per new version, after a one-time notice in the app. Settings -> About shows the event as sent and turns it off; HERDR_WEB_TELEMETRY=0, DO_NOT_TRACK, CI and test environments block it. The receiver in telemetry/ is a Cloudflare Worker over D1 that stores no IP address.
📝 SummarySummary by CodeRabbit
WalkthroughThe change adds anonymous install and update reporting, including server-side state and a D1-backed receiver. It adds an app notice and Settings controls, documents telemetry and opt-outs, and includes telemetry tests in the test and TypeScript input configuration. ChangesAnonymous Usage Telemetry
Priority: ➖ Normal Estimated code review effort: 4 (Complex) | ~45 minutes Change: Feature Merge Risk: 🔵 Low · up to Telemetry is currently gated on the notice and deduplicated on replay, but CI does not protect those behaviors against regression. The focused tests are worthwhile before relying on these privacy and count guarantees; the live Worker address also needs confirmation before release. Security Architecture ReviewSecurity architecture risk: 🟡 Moderate · up to Telemetry creates new privacy and public-service exposure. Concurrent app instances can overwrite a confirmed opt-out, and the public collection endpoint accepts persistent writes without application-level abuse limits. The supported risks concern telemetry privacy, collection capacity and count integrity—not access to terminals, files or accounts. Retained concerns

… state directory - The first event waits NOTICE_GRACE_MS (10 min) after the notice was shown, so Turn off on the notice stops it; before, it left the moment the notice drew. - Turning the switch off (or stopping the server) aborts a send in flight. - The state file is re-read before each decision and before saving, so a switch turned off by another server on the same state directory holds. - A state directory that cannot be written no longer stops the server from starting: telemetry logs once and sends nothing. - The Worker refuses a body over 2 KB as soon as it passes the limit instead of reading it to the end first.
…f is confirmed - notice_seen is posted two frames after the notice committed in a visible tab, not from a hidden or not-yet-painted one. - Turn off keeps the notice until the server has the switch off, and says so when that failed so it can be pressed again.

Independent review of the merge lane's commits c74606b, 2f8a0bc, 713ccd1 and b46f7e5 (lead session; lane rev-599 wrote them), head 713ccd1.
Verdict: merge.
What I ran, in a scratch copy of 713ccd1:
| Check | Result |
|---|---|
server/telemetry.test.ts + telemetry/worker.test.ts |
20 pass, 0 fail |
the same with server/telemetry.ts and telemetry/worker.ts from 91af8b2 (before the lane) |
6 fail: exactly the new cases (unwritable state directory, another server's opt-out holds, the first event waits after the notice, opt-out aborts a send in flight, a prerelease version is one event, an oversized body refused before it ends) |
Read:
- Nothing leaves before the notice was painted in a visible tab, and the first event waits ten minutes after it, so Turn off on the notice really sends nothing. Opt-out aborts a send in flight; the state file is re-read before each decision, so a second server cannot undo an opt-out.
- A send that fails (no receiver yet) is logged once and retried at the next start; an unwritable state directory makes telemetry silent instead of stopping the server.
- The Worker reads no header but the content type, binds every SQL value, keeps the day only, has Workers Logs off, and stops reading a body past 2 KB.
- The new route sits behind the token gate and the device roles; the POST needs same-origin and
x-herdr-update: 1; tests, CI,DO_NOT_TRACK,HERDR_WEB_TELEMETRY=0, the demo and remote bridges never send. telemetry/wrangler.tomlnames the D1 database (5cbb96eb-…) that the lead created for this account; the account's workers.dev subdomain isdevswha, matchingTELEMETRY_URL.
The Lows in #599 (comment) are fine as follow-ups. The lead deploys the Worker right after this merge.

…esh the front-page copy (#610) ## What - **New address.** The website and every install command now name https://herdrweb.dev/. The Pages custom domain is already live (Let's Encrypt cert, HTTPS enforced), and GitHub redirects every `devswha.github.io/herdr-web-ui/` path there with a 301, so `curl -fsSL https://devswha.github.io/herdr-web-ui/install.sh | sh` and the PowerShell one keep working (checked: they end on `https://herdrweb.dev/install.sh`). `herdrapp.dev` 301s to `herdrweb.dev` with the path kept. Changed: READMEs, INSTALL.md, guide, development and CONTRIBUTING docs, installer comments, `scripts/plugin.ts`, the Settings link, the film end card, the Windows install workflow, and the page's canonical, og and sitemap URLs. Past CHANGELOG entries keep the old address. - **Simplified Chinese page.** `site/zh/index.html` is the page in Simplified Chinese at `/zh/`. The header links `中文` ⇄ `EN`, and both pages carry hreflang alternates. `build-site.ts` now fills in the figures, unlinks missing media and writes the FAQ structured data for both pages, and lists both in `sitemap.xml`. The clip captions come from `README.zh-CN.md`; the mock agent screens (Codex prompt, task titles) stay in English, as the agents print them. - **Front-page copy for v0.4.0.** README (en/ko/ja/zh-CN) and the page now mention the customizable key bar (#508), typing the next message while an agent works (#520), and patch notes per update (#535, #560); the comparison's "Also" row mentions the four UI languages. The ko/ja/zh-CN READMEs gain the Windows install section, which only the English one had, and the Korean README the voice-input line. - **Header width.** With the language link, the header now fits from 316px up on both pages: under 560px the star chip hides (the stats strip right below shows the same count), and the nav hides under 960px instead of 900px. ## Not in this PR - The feature-clip and hero videos (and their alt text, which still names the old sidebar's **Needs you** and DONE/RUN labels) will be re-shot separately. - Devin CLI (#438) and anonymous usage counts (#599) are unreleased, so the front page does not mention them yet. The privacy FAQ ("Does my code or conversation leave my machine?") should mention the counts in the release that ships #599. - Google Search Console verifies the old URL; `herdrweb.dev` needs its own property. ## Checks - `bun run check fast`: 1776 pass, 0 fail. - `bun scripts/build-site.ts`: exit 0; `_site/zh/index.html` gets its figures and FAQPage data, and `sitemap.xml` lists both pages. - Both pages served from `_site/` in headless Chromium at 390 and 1440px: no 4xx, no page errors. Horizontal overflow measured every 2px from 300 to 1200px: none on `/zh/`, none on `/` from 316px up.

Release v0.4.2 from `main` at cc9701c. Stop before merge: the maintainer merges and runs the release. ## What's in it - Version 0.4.2 in `package.json` and `herdr-plugin.toml`. - CHANGELOG: `## [Unreleased]` cut into `## [0.4.2] - 2026-10-09`, compare links updated, the two #598 entries given their PR link. Outside contributors are credited as GitHub lists them as authors. - `release-summaries.json`: 0.4.2 patch notes in en/ko/ja/zh (new 5, improved 5, fixed 4). - `REMOTE_BUNDLE_VERSION` raised to `"22"`: the remote-PC bundle ships `server/`, `shared/` and `dist/` (`scripts/build-remote-bundle.ts`), and all three changed since remote-v21 (#543, #438, #599, #600, #601, #605 and others). A `remote-v22` tag is needed on the merge commit before the release. ## PRs since v0.4.1 #598, #524, #599, #603, #600, #601, #605, #438, #610, #607, #543 ## Whole-release review Codex astra (gpt-6-astra) over `v0.4.1..cc9701c`, looking for cross-PR problems: **no release blocker**. One Medium, verified by reading the code and left as a follow-up: in an OpenCode chat, "Show the whole output" fetched while a tool is still running can keep the older text if the tool later rewrites its output, because the output reference carries no revision. It affects only what is displayed until the row remounts; the fix needs a new protocol field, so it is out of scope for a release PR. ## Checks - `bun run check fast`: green locally (1928 pass, 6 skip, 0 fail; typecheck, build, generated types). - `server/release-notes.test.ts` and `scripts/release-notes.test.ts`: 27 pass; `bun scripts/release-notes.ts 0.4.2` renders the notes.

… bar order (#661) ## What The front page, brought to v0.4.2. Docs only: the four READMEs and both site pages. No app code, no CHANGELOG. - **Devin CLI (#438)** joins the chat-view agents: the feature line and the "Which agents" FAQ in all four READMEs and on `/` and `/zh/`. The FAQ says when it is a chat (herdr or the running process names the session, as `devin --resume` with an ID does) and when it stays the terminal (a plain `devin`), as the guide does. On the site, the 01 example's `OpenCode 2` row becomes `OpenCode 2 · Devin CLI`. - **Anonymous usage counts (#599)**: the "Does my code or conversation leave my machine?" FAQ now says the app sends a count on install and on each update (version, OS, install method, random ID, no IP stored) and that Settings → About → Anonymous usage counts shows and turns it off. Since v0.4.2 the answer was incomplete without it. - **Key bar order (#607)**: the site's key bar example follows the new default, Esc, Tab, Ctrl+C, Ctrl, Alt, Shift, Enter, arrows (read from `DEFAULT_KEY_BAR_ITEMS`). The site FAQ writes "`devin --resume` with a session ID" instead of `<id>`: `build-site.ts` decodes only `&` when it writes the FAQPage data, so `<id>` would have reached it literally. ## Checks - `bun scripts/build-site.ts`: exit 0. The FAQPage data on both pages has 7 questions, includes the Devin and anonymous-count text, and holds no HTML entities. - Both pages in headless Chromium: no 4xx, no page errors; the 01 example's labels are not clipped at 390 or 1440px.

It never reads the sender's address or any header but the content type, stores the day rather than the time, keeps each (install, event, version) once, and has Workers Logs off. Deploy steps and the queries to read the counts are intelemetry/README.md.A failed send is logged once and tried again at the next start; it never loops. Turning the switch off aborts a send in flight, the state file is re-read before each decision (two servers on one state directory agree), and a state directory that cannot be written leaves the app running with telemetry silent.
