Meter anonymous Ask AI: quota gate, countdown, and sign-in wall#436JakeSCahill wants to merge 5 commits into
Conversation
The anonymous Ask AI tier (Chat SDK drawer) now asks the docs backend (docs-site POST /kapa/quota) before every question and, once the visitor's free questions are spent, shows a sign-in wall instead of the composer. The gate lives in persistentApiService.submitQuery because every way to ask funnels through it: the composer, suggestion chips and cards, retry, window.submitChatQuery from code blocks and the playground. Gating in the component would leave each entry point to remember the check. It also guards the Stop-during-quota-check race: without it, an answer could start streaming after the user had already stopped it. ChatSdkInterface peeks the budget on mount (which doubles as the warm-up for the backend's scale-to-zero database), counts down in the upsell bar, and renders QuotaWall in two shapes: a hero variant in place of the welcome screen when there is no conversation to keep, and a compact footer variant that replaces only the composer when there are answers on screen, so nothing the reader already got is taken away. The wall reuses the agent tier's signin-* classes and carries disclosed=1 because the privacy note is inline. Fails open everywhere. A missing endpoint (older site, a docs-ui preview), a timeout, or a degraded verdict all mean the question goes through and no count is shown. A 404/405 sets a sessionStorage marker so a build running against a site without the function does not pay a doomed round trip per question.

📝 WalkthroughWalkthroughThe change adds anonymous question quota support. A new client queries and caches quota verdicts, handles unavailable endpoints, and publishes quota events. The API service checks the quota before submitting a question and suppresses submissions stopped during the check. The chat interface displays remaining questions, reset information, and sign-in walls when the quota is exhausted. New CSS styles support hero and footer quota walls. Priority: ➖ Normal Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟡 Moderate · up to Anonymous Ask AI quota handling can incorrectly retain a sign-in wall, show an active composer after the free quota is spent, or reject questions during degraded quota service responses.

…dict, order them - The backend answers the third of three with allowed + remaining 0 so Kapa can still reply. Treat that as exhausted once the answer settles, so the composer does not sit live under "0 free questions left" until the next submission is refused into an empty bubble. quotaExhausted() owns the rule. - Fail-open verdicts are now published too, so a walled visitor whose next check fails gets the composer back, matching what the gate would allow. - Verdicts carry a sequence number; the slow mount-time peek can no longer overwrite a faster consume. - Degraded verdicts are pinned to allowed at the boundary. - Drop the unused isExhausted export. - tests/anon-quota: node --test suite over the real module, wired into validate-build.

The gate location (persistentApiService.submitQuery) is the right choke point and the fail-open rules are thorough. I merged v4.1.0 main into the branch (the conflict was only the test registration in package.json and the workflow; both entries kept, tests and lint pass).
Four things I'd fix before merge, one wall-copy item that pairs with a comment on docs-site #231, and one design note, all inline.
| useEffect(() => { | ||
| const onQuota = (e) => setQuota(e.detail) | ||
| window.addEventListener(QUOTA_EVENT, onQuota) | ||
| peekQuota().catch(() => {}) // fails open inside; nothing to handle here |
There was a problem hiding this comment.
Should fix. This peek runs in a mount effect, and the component mounts on every anonymous pageview, not on drawer open: chat-panel is in body.hbs unconditionally, AskAI.jsx calls createRoot(…).render() on DOMContentLoaded, and drawer open/close is CSS-only. So every page load costs a function invocation, two strong-consistency Blobs ops, and one or two Neon queries; Neon can never scale to zero while anyone is browsing; and the endpoint flood guard (sized in ratelimit.mjs for a peek per drawer open) trips on ordinary browsing behind a shared IP. Once it trips, kapa-quota returns rate_limited for peeks and consumes from that IP for the rest of the window, anonQuota.js maps that to openVerdict(), and everyone behind that NAT asks uncounted. The PR text's "peek on drawer mount… while the user is still typing" describes the intent, not what runs.
Suggest hanging the peek off the existing docs-account:warm / openPanel hook (which already fires only on deliberate opens) and caching the verdict in sessionStorage until reset_at, the way probeSession caches kapa-session-state.
There was a problem hiding this comment.
Fixed, and you were right about the mechanism end to end. Two deviations worth flagging.
I used a dedicated docs-chat:open rather than docs-account:warm. That event is gated on !/rp_docs_auth=1/, so a reader carrying a stale auth cookie with an expired session lands on the anonymous drawer and would never have got a peek, and so never a countdown. The new event fires on the same !restored condition, just without the cookie test. The bump widget could not tell restore from a deliberate open at all (its restore path called the same argument-less openPanel()), so it now takes the restored flag its sibling already had.
The home page's inline Ask AI still peeks on mount: #kapa-chat-root has no drawer to wait for, and its composer is on screen immediately. schedulePeek() reads the data-mounted marker AskAI.jsx already stamps on whichever element it chose, so that check follows the real mount decision rather than re-deriving it.
I did not add the sessionStorage caching. With the peek down to once per deliberate open, it saves a request only for someone who opens the drawer on several pages in one session, and a cached verdict can go stale against a consume from another tab, which is the direction that shows a wall to someone who has questions left. Happy to add it if you still want it, but it seemed worth you weighing that first.
Five tests, and the negative controls: restoring the mount peek fails 2, dropping the once-per-pageview guard fails 1, never peeking inline fails 1.

Should fix. This early return is correct, but the effect that publishes window.submitChatQuery (around L308–318) still has deps [hasInteracted, isBusy], so the code-block and playground "Ask AI" entry point holds a doQuery whose exhausted is frozen at mount. Scenario: a visitor who spent all 3 yesterday loads a page; the effect captures exhausted=false; the peek returns 429 and the hero wall renders; neither dep changed so the effect doesn't re-run; a click on a code block's "Ask AI" skips this gate, fires ADD_NEW_QA and the Heap event, the consume is refused, and you get an orphan question with no bubble above the footer wall (the retry row is suppressed by !exhausted). The reverse also holds after a fail-open verdict flips it back. Add exhausted to the deps, or read the latest doQuery through a ref.
There was a problem hiding this comment.
Fixed. doQuery now lives in a ref updated after every render, and the global registers once with [], so there is no dep list to keep in step and no next captured value to forget. Adding exhausted to the old list would have worked today and left the same trap for whatever doQuery closes over next.

| abortCurrent () { |
There was a problem hiding this comment.
Should fix. abortCurrent() records abortedSubmission and forwards to the default service, but never cancels this wrapper's own pending step: the consumeQuota() await, whose AbortController is local to ask(). So a stopped submission's promise stays pending for up to 4s, and the SDK's unconditional finally { SET_IS_GENERATING false } (dist/index.mjs around L883–901, no request-id guard) fires late and clears both busy flags for whatever submission is in flight by then. Reachable via Stop then "Try again" within one round trip: #1 awaiting consume, Stop, Try again, #2 ADD_NEW_QA, #1's consume resolves, SDK #1 finally runs while #2 is preparing or streaming. Effects: composer re-enabled and Stop replaced mid-stream, a false "No answer came back" under an in-flight question, and the wall replacing the composer mid-stream if #2 was the last permitted question. The baseline DefaultKapaApiService never has this because its fetch rejects with AbortError in the same tick.
Suggest racing the consume against a per-submission abort promise that abortCurrent() resolves (and not announcing a degraded verdict on external abort).
There was a problem hiding this comment.
Fixed. The consume is now raced against a per-submission stop promise that abortCurrent() resolves, so a stopped submission settles at once instead of waiting out the 4s timeout and letting the SDK's unguarded finally land on whatever is in flight by then.
On your parenthetical: I chose not to abort the consume's fetch, so there is no external-abort verdict to suppress. The server has already been asked by the time Stop can arrive, so the question is spent either way, and letting the request finish means its real verdict reaches the countdown. Aborting it would publish a degraded verdict and tell the reader they have a question they do not.
Tested by running the service with the SDK stubbed and a fetch that never resolves: abortCurrent() then awaiting the submission has to return, and nothing may reach Kapa. Raced against a 500ms deadline in the test so a regression fails fast rather than hanging the run. Removing the race fails that test alone.

There was a problem hiding this comment.
Should fix. Adding && !exhausted here also swallows the admitted-then-failed case: the visitor's last permitted question (server says allowed: true, remaining: 0) fails at Kapa, and instead of "No answer came back" they get a bare question, no bubble, no explanation, and the composer replaced by a wall whose copy implies the question was answered. The chat_error_docs_home Heap event is suppressed too. The code's own comment calls the captcha abort the most common failure, so a third of those for walled visitors land here. Retry would be refused anyway, so the gap is the explanation and the observability, not the button. Narrower condition: exclude only quota?.allowed === false (the refused exchange the comment targets).
There was a problem hiding this comment.
Fixed, narrowed to quota?.allowed === false as you suggested. The last permitted question really was admitted and really was sent to Kapa, so a client-side death there now gets the normal explanation and its chat_error_docs_home event, and only the refused exchange is left to the wall.

Pairs with a comment on docs-site #231. When the per-IP ceiling (30/day) refuses, the backend's 429 currently reports the visitor's budget and drops the reason, so this title tells someone who asked zero questions "You've used your 3 free questions". Once the 429 carries blocked_by, branch the title here ("Too many questions from your network today"); reset_at already gives the right "come back in N hours" line.
There was a problem hiding this comment.
Done on both sides. docs-site PR 231 now sends blocked_by on the 429, and the wall branches the title to "Too many questions from this network today" plus a lead sentence saying the limit is per network. reset_at carries the IP window already, so the "come back in N hours" line needed nothing.
It falls back to the existing copy when the field is absent, so merge order between the two does not matter.

There was a problem hiding this comment.
Design note, not blocking. await consumeQuota() runs (and the server increments n) before the Stop check at L58, so a Stop pressed during the 0–4s quota round trip still spends one of the visitor's three questions with no answer delivered, and then walls them if it was the last one. Moving the check up is a no-op since Stop can only arrive during the await, and no refund exists. This is the same class as the Kapa bot-check case you already flagged in the description, so it probably wants a backend answer (reserve/confirm-on-first-token, or a refund keyed to the consume). At minimum I'd narrow the "fixed while here" Stop claim in the PR text to the streaming half.
There was a problem hiding this comment.
Narrowed the PR text as you asked: the Stop claim now says the streaming half only, and states plainly that a question stopped mid-round-trip is still spent, with the reserve-then-confirm or refund options named as the backend answer alongside the Kapa bot-check case.
Worth noting the two are not quite the same size now. The unstopped-submission half of that thread turned out to be a live bug rather than a design gap, and is fixed above.
The peek fired from ChatSdkInterface's mount effect, and that component mounts on every pageview: the drawer's root markup ships in body.hbs site-wide and AskAI.bundle.js is a plain defer script, so the React tree goes up whether or not anyone ever opens Ask AI. Every anonymous pageview therefore cost a function invocation and a Neon read before the reader had shown any interest in asking a question. Three things went wrong with that: - It kept the scale-to-zero database permanently resumed rather than warming it just in time, which is the opposite of what the warm-up is for. - It scaled with page count instead of with people, so the endpoint's traffic said nothing about Ask AI usage. - It spent the per-IP flood budget on navigation. That bucket is 300 per 600s and docs-site lib/oauth/ratelimit.mjs sizes it for "a peek per drawer open plus a check per question, across everyone behind one NAT"; at a peek per pageview a large shared address can exhaust it by browsing. The consume in front of a real question then answers rate_limited, which fails open, so the countdown silently disappears and metering stops for everyone behind that address. That is the population it should work for most. schedulePeek() now owns the timing. On the docs home page's inline Ask AI, whose composer is on screen with no interaction, it peeks on mount as before. In the drawer it waits for docs-chat:open, which 19-chat-panel.js and the bump widget's inline logic dispatch on a deliberate open and not on their page-load restore path. That is the same line 19-chat-panel already drew for the /auth/warm pre-warm, for the same reason, and its comment says so. The bump widget could not tell the two apart, since its restore path called the same argument-less openPanel(), so it gets the `restored` flag its sibling already had. Nothing arrives later than before: opening the drawer and landing on the home page both precede typing, so the countdown and the wall are still in place before there is a question to spend, and the database is still warm ahead of the consume that gates it. Once per pageview, since a second open learns nothing and every later verdict comes from the consumes. Tests: 5 new in tests/anon-quota (no request on mount, one peek on open, not twice, inline mount still peeks on mount, teardown unsubscribes), and the fake browser now registers and fires listeners for real rather than stubbing addEventListener. Negative controls: restoring the mount peek fails 2, dropping the once-per-pageview guard fails 1, and never peeking inline fails 1, each the intended assertion and nothing else.

…wall copy Four fixes from @micheleRP's review of PR 436. **window.submitChatQuery held a stale doQuery.** The effect publishing the global ran on [hasInteracted, isBusy], so the doQuery it captured froze `exhausted` at whatever it was when those last changed. A reader who spent their questions on a previous day loaded a page, the peek returned 429 and raised the wall, neither dep changed, and a code-block "Ask AI" click still went through with exhausted frozen false: the SDK recorded a question, the consume refused it, and the result was an orphan bubble above the wall with the retry row suppressed. The same staleness ran the other way after a fail-open verdict. doQuery now lives in a ref updated after every render, and the global is registered once, so there is no next captured value to forget. **Stop did not stop a submission waiting on its quota check.** abortCurrent recorded the submission and forwarded to the default service, but the wrapper's own pending await was consumeQuota, whose AbortController is internal to anonQuota.js. So a stopped submission stayed pending for the client's full 4s timeout, and the SDK's unconditional finally (no request-id guard) then fired against whatever was in flight by then: Stop, "Try again", and #1's late finally re-enables the composer and swaps out Stop mid-stream, or reports "No answer came back" under a live question, or drops the wall over #2 if that was the last permitted one. The consume is now raced against a per-submission stop promise that abortCurrent resolves. The consume itself is deliberately not cancelled: the server has already been asked by the time Stop can arrive, so the question is spent either way, and letting it finish means its real verdict reaches the countdown where aborting the fetch would publish a degraded one and tell the reader they have a question they do not. **`&& !exhausted` on queryFailed swallowed too much.** It also covered the last permitted question (allowed, remaining 0), which was admitted and really was sent to Kapa. When that one dies client-side the reader got a bare question, no bubble, no explanation, and a wall whose copy implies it was answered, and the chat_error_docs_home event was suppressed with it. Narrowed to a refused exchange, which is the only one the wall actually explains. **The wall told network-limited readers they had spent their own questions.** The 429's counts are always the visitor's, so someone refused by the shared per-IP ceiling saw "You've used your 3 free questions" having used one. Reads blocked_by (added in the companion docs-site PR) and branches the title and the lead sentence; reset_at already produced the right "come back in N hours" line. Falls back to the old copy when the field is absent, so it does not depend on merge order. Also replaced the gate test that asserted `if (!verdict.allowed)` by regex over the source. It broke on the restructure above, and a regex over source cannot tell whether the gate works. The service now runs in the test with only the Kapa SDK and the threadId store stubbed, asserting what actually reached Kapa: nothing on a refusal, the question on a degraded verdict, and nothing after Stop, that last one racing a deadline so a regression fails fast instead of hanging the run. Tests: 20 in tests/anon-quota, up from 16. Negative controls: removing the Stop race fails the Stop test alone, and dropping the blocked_by mapping fails the wall-copy test alone. The two React-component fixes have no component test harness here and were verified by build and by reading the render paths. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

What
Frontend half of metering anonymous Ask AI at 3 questions per 24 hours. Backend (the endpoint and the counter) is the companion docs-site PR, linked in the first comment. Merge order does not matter for safety: this fails open when the endpoint is absent. The limit only bites once both are live.
What the visitor sees
/login. Carriesdisclosed=1because the privacy note is inline.login_url), no dead button: the wall says when they can ask again.The last permitted question is the subtle case: the backend answers it with
allowed: true, remaining: 0so Kapa can still reply, so the wall goes up once that answer has finished streaming (Stop stays available until then).quotaExhausted()inanonQuota.jsowns that rule.Signed-in users are unaffected (Agent SDK path, never touches this code).
Where the gate is, and why there
persistentApiService.submitQueryconsumes one question viaPOST /kapa/quotabefore calling Kapa, and refuses to call Kapa on a no. Every way to ask funnels through it (composer, chips, cards, retry,window.submitChatQueryfrom code blocks and the playground), so this is the one place a new entry point cannot bypass. The component also blocks pre-submit when it already knows the budget is gone, so the SDK never records a question with no answer.Also fixed while here, on the streaming half only: pressing Stop during the quota round trip used to let the answer start streaming afterwards, and used to leave the submission pending for the client's full 4s timeout, so the SDK's own unguarded
finallyfired against whatever question was in flight by then. A submission counter plus a stop promise the consume is raced against.What Stop still does not do is give the question back. The server has already been asked by the time Stop can arrive, and there is no refund, so a question stopped mid-round-trip is spent. That is the same shape as the Kapa bot-check failure below and wants a backend answer (reserve then confirm on first token, or a refund keyed to the consume) rather than a client fix.
Fails open, everywhere
Missing endpoint, timeout, degraded verdict, endpoint-level rate limit: the question goes through and no count is shown. Every verdict is published, the fail-open ones included, so a walled visitor whose next check fails gets the composer back, matching what the gate would allow. Verdicts carry a sequence number so the slow peek can never overwrite a faster consume. A 404/405 sets a
sessionStoragemarker so a docs-ui preview (no backend) does not pay a doomed round trip per question. The peek also warms the backend's scale-to-zero database while the user is still typing, so the consume in front of the first question does not pay the cold start.Where the peek fires, and why not on mount
The peek is one function invocation and one Neon read, so its trigger decides whether this endpoint's traffic tracks Ask AI users or pageviews. It cannot live in
ChatSdkInterface's mount effect: the drawer's root markup ships inbody.hbssite-wide andAskAI.bundle.jsis a plaindeferscript, so the React tree mounts on every pageview whether or not anyone opens Ask AI.Peeking from there would have cost a request per anonymous pageview, which does three unwanted things. It keeps the scale-to-zero database permanently resumed instead of warming it just in time. It scales with page count rather than with people. And it spends the endpoint's per-IP flood budget on navigation: that bucket is 300 per 600s and docs-site
lib/oauth/ratelimit.mjssizes it for "a peek per drawer open plus a check per question, across everyone behind one NAT", so at a peek per pageview a large shared address can exhaust it by browsing. The consume in front of a real question then answersrate_limited, which fails open, and metering silently stops for everyone behind that address.So
schedulePeek()owns the timing:#kapa-chat-root): peeks on mount. Its composer is on screen with no interaction, and there is no drawer to wait for.docs-chat:open, which19-chat-panel.jsand the bump widget's inline logic dispatch on a deliberate open and deliberately not on their page-load restore path. That is the same line19-chat-panel.jsalready drew for the/auth/warmpre-warm, for the same reason, and its comment says so. The bump widget could not tell the two apart (its restore path called the same argument-lessopenPanel()), so it gets therestoredflag its sibling already had.Nothing arrives later than it did: opening the drawer and landing on the home page both precede typing, so the countdown and the wall are in place before there is a question to spend, and the database is warm ahead of the consume that gates it.

Negative controls: restoring the mount peek fails 2, dropping the once-per-pageview guard fails 1, never peeking inline fails 1, removing the Stop race fails 1, and dropping theblocked_bymapping fails 1, each the intended assertion and nothing else.netlify dev --offline(Blobs/in-memory store) serving an Antora build with this bundle. Peek showed "3 free questions left"; each question counted down (2, 1); after the third answer finished, the footer wall replaced the composer with every answer still scrollable; after a reload the peek returned 429 and the hero wall replaced the welcome screen, with the sign-in link carryingdisclosed=1andreturn_to, and "Or come back tomorrow." fromreset_at.
