finding(console): /organizations leaves the viewport centre uncovered for ~453ms after the org gate has handed off

[claude]

Found while implementing #6507 (PR #6565), on a page that card did not send me to. One measurement, no rate.

The reading

Driving a signed-in mock boot into RequireOrganization's "no org at all, multi-org enabled" decision, with the coverage probe from e2e/console-boot-indicator.spec.ts (hit test at the viewport centre on every mutation and every animation frame after React's first commit):

• 26 covered samples, then 22 uncovered samples
• every uncovered sample on /organizations — none on the entry path
• the centre hit test lands on a div that is outside both #root and #boot-splash
• the window spans roughly 453 ms, first sample at t=2489 ms

That signature — the viewport centre resolving to something the app is not responsible for — is what this campaign (objectui#6378, #6506, #6507) treats as a blank viewport.

Why this is filed separately from #6507

The redirect that #6507 converts had already handed off cleanly when these samples were taken. The gate's own window came back empty of findings; every uncovered sample is on the destination page, after arrival. Asserting on it inside #6507's tests would have made them red for a reason pointing away from the redirect they exist to guard.

What is NOT established

• Whether this is a real blank frame or a probe artifact. A full-screen portal or overlay rendered outside #root would produce the same reading without any visible defect. That hypothesis was not tested — checking it is most of the work here.
• Any rate. One measurement, one scenario, one fixture. objectui#6378's figures came from 102 paired boots; this is not comparable to them.
• Whether a real (non-mocked) boot reaches the same state. The organizations surface was reached with mocked endpoints.
• The related scenario ("member of orgs, none active") recorded zero samples of any kind, because that surface performs a full-page navigation which tears down an init-script probe along with the document. That is a fixture limit, and it also means this page is awkward to instrument the usual way.

Reproducing

Production apps/console bundle, boot endpoints mocked to return a signed-in session with an empty organization list and features.multiOrgEnabled: true, entry at /home. Probe as in e2e/console-boot-indicator.spec.ts's Console boot continuity test. Browser: pre-installed Chromium 141 at PLAYWRIGHT_BROWSERS_PATH=/opt/pw-browsers, driven via executablePath (do not run playwright install — that CDN is blocked).

PM note (domain:ui seat, session session_011SfZeFWrhGLHmfq61xbz4q) — context for grading, not a grading. ⛔ No labels applied; domain:*, type and severity are the triage seat's to produce.

One comparison that is not in the card and that bears on how it gets read.

The window measured here is ~453 ms. The campaign this came out of measured 41–147 ms.

objectui#6378 established the blank-viewport defect with a CDP frame ledger against a DOM ledger on a shared clock, and the three gates it fixed showed 41–147 ms of empty #root — present on 102/102 boots, producing a full-viewport white frame on 67/87. That was considered severe enough to justify RedirectWithSplash, PR #6506, and the follow-up campaign that became #6507.

So this reading is roughly three times wider than the widest window that campaign treated as a defect, and it occurs after the org gate has already handed off cleanly — meaning it is not the handoff shape #6506 and #6507 fixed. Whatever it is, it is a different mechanism.

What is NOT established, stated as the filer stated it: one measurement, no rate, and the portal-overlay hypothesis explicitly untested. It was found on a page the dev was not dispatched to, which is why it is filed rather than folded into PR #6565.

⭐ Why this seat is flagging it rather than sitting on it: read as "a probe artifact on a page nobody asked about", this card looks like housekeeping. Read against the campaign's own numbers, it is the widest uncovered window anyone has measured in this codebase. Those two readings deserve different grades, and only the second one is available if you have the 41–147 ms figure to hand.

If it grades into this lane, this seat will take it. If the right first step is a rate rather than a fix — the filer has one boot, not a distribution — that framing would match how #6378 itself established its case.

Triage: lands in apps/console / app-shell boot surface ⇒ domain:ui, promoted straight to pm:queue, type Task. Rationale: read against the campaign's own numbers (lane PM's comment above: #6378 treated 41–147 ms as defect-grade; this window is ~453 ms, on 22 consecutive samples), this is the widest uncovered-viewport window measured in this codebase — that is not housekeeping, even at n=1.

Charter (premise-first, in this order):

1. Establish a rate and test the portal-overlay hypothesis first — the filer's own caveat: a full-screen portal/overlay outside #root would produce this reading with no visible defect. Method should follow perf(console): a one-frame white flash right AFTER LoadingScreen's first paint (40-230 ms, ~1 boot in 3) #6378's own case-building (paired boots, frame ledger vs DOM ledger). premise_still_valid: false (probe artifact) is a legitimate and valuable outcome — report it, close, no fix.
2. Only if a real blank frame is established: diagnose the /organizations post-handoff mechanism (it is NOT the fix(app-shell,console): keep the splash painted across the console boot redirects #6506/finding(app-shell): six more boot gates still hand off from LoadingFallback to a null-rendering <Navigate> #6507 handoff shape — the gate had already handed off cleanly) and fix within the campaign's existing idiom.

Not a Bug yet by the type test: no declared contract is measurably violated until step 1 establishes the blank frame is real.

1. Premise first. A refutation is a success outcome.

Triage's charter, in order and binding:

1. Establish a rate and test the portal-overlay hypothesis first — the filer's own caveat: a full-screen portal/overlay outside #root would produce this reading with no visible defect. Method should follow perf(console): a one-frame white flash right AFTER LoadingScreen's first paint (40-230 ms, ~1 boot in 3) #6378's own case-building (paired boots, frame ledger vs DOM ledger). premise_still_valid: false (probe artifact) is a legitimate and valuable outcome — report it, close, no fix.
2. Only if a real blank frame is established: diagnose the /organizations post-handoff mechanism (it is NOT the fix(app-shell,console): keep the splash painted across the console boot redirects #6506/finding(app-shell): six more boot gates still hand off from LoadingFallback to a null-rendering <Navigate> #6507 handoff shape — the gate had already handed off cleanly) and fix within the campaign's existing idiom.

⛔ Do not skip to step 2. The card is n=1 with the overlay hypothesis explicitly untested by its own filer. If a full-screen portal outside #root explains it, the correct deliverable is that measurement and a closed card.

2. ⭐ The browser is available — do not go looking for one

This matters because the previous dev on this campaign lost time to it. A working Chromium is pre-installed: PLAYWRIGHT_BROWSERS_PATH=/opt/pw-browsers is already exported, /opt/pw-browsers/chromium symlinks to chromium-1194/chrome-linux/chrome, and it runs — Chromium 141.0.7390.37, headless smoke test passes.

⛔ Never run playwright install / npx playwright install chromium — that hits a CDN this environment blocks (403), and the 403 reads like "no browser exists" when a browser does. If the repo pins a @playwright/test expecting a different build, launch with executablePath: '/opt/pw-browsers/chromium'.

⚠️ One trap: find /opt/pw-browsers/chromium -name chrome returns nothing, because find does not descend a symlink without -L. That absence is an artifact.

3. Prior art you should reuse rather than rebuild

• perf(console): a one-frame white flash right AFTER LoadingScreen's first paint (40-230 ms, ~1 boot in 3) #6378 is the method: a CDP frame ledger correlated against a DOM ledger on a shared performance.timeOrigin, with the white rule (no colour channel below 242). That is how the 41–147 ms figure was established, and it is the standard this card's number has to be measured against.
• finding(e2e): the boot-continuity probe cannot fail for any gate that decides after a session exists #6569 carries a reusable signed-in endpoint set built by finding(app-shell): six more boot gates still hand off from LoadingFallback to a null-rendering <Navigate> #6507's dev — session, metadata, org and app endpoints — plus the ablation and 20× throttling results. Read it before building a fixture; it may save you the whole scaffold.
• e2e/console-boot-indicator.spec.ts on main now documents what that boot reaches and what it does not, including why the pre-React #boot-splash counts as covering. That last fact is directly relevant: the splash counting as covering is what made finding(app-shell): six more boot gates still hand off from LoadingFallback to a null-rendering <Navigate> #6507's per-site scenarios unable to fail, and it may equally explain or fail to explain this reading.

4. ⛔ The instrument must be able to fail

The single most important lesson from #6507, and it applies with more force here because you are establishing a defect rather than fixing a known one: an assertion that cannot fail is not evidence. #6507's dev built signed-in scenarios that stayed green against a bundle rebuilt from ablated source, even at 20× CPU throttling, and deleted them rather than commit them.

So: whatever probe you build, show it reds on a case you know is uncovered and greens on a case you know is covered, before you trust either reading about /organizations. A control arm that must read "covered" is what keeps an "empty" reading falsifiable.

5. Why the number matters, so you can judge your own result

#6378 treated 41–147 ms as defect-grade — present on 102/102 boots, a full-viewport white frame on 67/87 — and that justified RedirectWithSplash, PR #6506, and the campaign that became #6507. This card reports ~453 ms across 22 consecutive samples, roughly three times the widest window that campaign acted on, and it occurs after the org gate has already handed off cleanly.

So if it is real, it is the widest uncovered window measured in this codebase and a different mechanism from the one the campaign fixed. If it is not real, that is worth knowing before anyone builds on the number — which is why step 1 comes first.

6. Scope

Whatever step 1 requires. ⛔ No fix without step 1's result. ⛔ Do not modify RedirectWithSplash or any of the seven sites #6565 just converted — this is explicitly not that shape.

Shadow check: no in-flight card touches the boot path. #6567 is in apps/console/src/components/.

Report the rate, the control-arm behaviour, and what you did not establish. "One boot, no distribution" was the filer's honest limit; do not inherit it silently.

Step 1 result: probe artifact. The filer's own untested hypothesis is the answer.

premise_still_valid: false. No fix, no PR. What the viewport centre resolves to on /organizations is the "Create a workspace" modal dialog, rendered through a Radix portal as a body-level sibling of #root, over a fully rendered page. Nothing is blank at any point.

The rate (n=20, production bundle, Chromium 141)

Same fixture as the card: signed-in mock boot, empty organization list, features.multiOrgEnabled: true, entry at /console/, hit test at the viewport centre on every mutation and every animation frame after React's first commit. Trailing sample window 500 ms, which is what the card's spec uses.

• 20/20 boots reproduce the card's reading. 12-28 uncovered samples per boot (median 21), spanning 304-618 ms (median 446 ms). The card's "22 uncovered samples, ~453 ms" is the median of this distribution, not an outlier.
• 0 white frames on 391 post-mount frames. CDP Page.startScreencast at everyNthFrame: 1, every frame classified by objectui#6378's white rule (no colour channel below 242), correlated with the DOM ledger on a shared performance.timeOrigin. The minimum colour channel inside every uncovered window was 0 - the modal's 80%-black overlay.

What the DOM holds at those samples, on 20/20 boots:

reading	value
location.pathname	/organizations
centre element, first uncovered sample	div[data-state=open].fixed.inset-0.z-50 (Radix DialogOverlay)
centre element, later samples	div.grid.gap-4.py-4 inside form inside div#radix-_r_h_[role=dialog][data-state=open]
open modal dialog present	true
#root child elements / box / text	2 / 1280x720 / 196 characters
body computed pointer-events	none
#root aria-hidden	null

A screenshot taken at the first uncovered sample shows the "Create a workspace" dialog centred over the rendered "Your Workspaces" page, with the header, search box and "New workspace" button all painted behind it.

Why the full hit stack does not rescue the reading either

The obvious repair - read document.elementsFromPoint instead of elementFromPoint, so a portal on top does not hide the app underneath - does not work here. Radix's DismissableLayer parks pointer-events: none on <body> while a modal is open, and hit testing skips pointer-events: none elements, so #root and its entire subtree leave the stack. Measured: uncoveredStack equals uncoveredTop on all 20 boots.

The instrument that does separate them is the pixel ledger. Filed separately as #6578.

The mechanism, in source

packages/app-shell/src/console/organizations/OrganizationsPage.tsx opens the dialog on purpose for exactly this user:

const firstRunNoOrg = orgList.length === 0 && canCreateOrg;
if ((wantsCreate || firstRunNoOrg) && !createOpenedRef.current) { ... setIsCreateOpen(true); }

with the comment "land them straight on the 'name your workspace' form instead of an empty picker (one hop fewer on first run)". CreateWorkspaceDialog renders DialogContent inside DialogPortal (packages/components/src/ui/dialog.tsx:45), with DialogOverlay at fixed inset-0 z-50 - both body-level siblings of #root.

So the reading is not merely benign, it is the intended first-run UI, and it appears because the org gate handed off cleanly.

The "~453 ms window" does not close - it tracks the sampling window

Same scenario, only the trailing sample window changed:

trailing settle	uncovered samples	span
500 ms	22-24	507-520 ms
1500 ms	81	1747 ms
3000 ms	137-161	2841-3019 ms

1:1 with sampling time. This is a steady state that lasts as long as the dialog is open (i.e. until the user types a workspace name or dismisses it), not a window that opens and closes. The card's 453 ms is a property of when the probe stopped sampling, not of the page. It is therefore not comparable to objectui#6378's 41-147 ms, and the "3x wider than anything the campaign acted on" framing does not survive the measurement.

The instrument can fail - control arms (n=3 each, signed-out /login boot, settle 1500 ms)

arm	uncovered (top rule)	uncovered (full-stack rule)	white frames	min channel
untouched - must read covered	0	0	0/31	n/a
#root emptied + splash removed - must read uncovered	34-36	34-36	6/34	246
body-level overlay, app hit-testable underneath	33-38	0	0/34	0
body-level overlay + body{pointer-events:none} (Radix modal shape)	38-42	38-42	0/33	0

Row 2 is the falsifiability proof: a real blank viewport in the real bundle reds both DOM rules and trips the white rule, min channel 246 - the bare page background is white, which is the #6378 flash. Row 1 is the control arm that must read "covered" and does. Rows 3-4 reproduce the card's signature deliberately, with a fully visible app and no defect.

Under objectui#6378's throttled profile the reading gets weaker

20x CPU throttling (Emulation.setCPUThrottlingRate), n=6: uncovered samples drop to 0-8 (median 2), white frames 0/749. A real timing race widens under throttling; this narrows, because the dialog simply opens later and fewer of the fixed 500 ms of samples land while it is up. That is the opposite direction from a defect.

What I did NOT establish

• A real, non-mocked boot. Everything here is the mocked endpoint set from finding(e2e): the boot-continuity probe cannot fail for any gate that decides after a session exists #6569. The dialog is opened from session state (orgList.length === 0 && canCreateOrg), not from anything the fixture does, so a real zero-org boot should reach the same state - but that is inference from source, not a measurement.
• The sibling scenario ("member of orgs, none active") is still uninstrumented. It performs a full-page navigation that tears down an init-script probe with the document, exactly as the card said. I did not attempt it; it is not needed to settle this card.
• A zero-blank-frame proof. The screencast emits frames on compositor swaps, so a perfectly static period emits few frames. 391 post-mount frames (n=20) and 749 more under throttling contained no white frame; that is a strong bound, not a proof of zero.
• Whether other body-level portals (toasts, popovers, command palette) produce the same false positive. Only the dialog shape was measured. Recorded in finding(e2e): the boot-continuity coverage rule reads an open modal as a blank viewport #6578.

Deliverable

No code. The harness lives outside the repo and is not committed; the branch claude/issue-6570-organizations-uncovered-window carries no commits beyond the contract's write-route probe push. Recommend closing this card as not_planned (probe artifact), with #6578 carrying the reusable half.

Premise refuted. Closing not_planned — no defect, no code changed.

Dispatched premise-first. The step-1 probe was authorised to kill the card, and it did. Summary of what was measured, plus an independent source check by this seat that does not depend on the probe at all.

What the "uncovered viewport" actually is

It is the CreateWorkspaceDialog, deliberately auto-opened on the first-run path — a body-level portal sibling of #root, not a blank frame. Confirmed by this seat directly against main, independently of the probe, in packages/app-shell/src/console/organizations/OrganizationsPage.tsx:

:149  // they have nothing to pick, so land them straight on the "name your
:150  // workspace" form instead of an empty picker (one hop fewer on first run).
:156  const firstRunNoOrg = orgList.length === 0 && canCreateOrg;
:157  if ((wantsCreate || firstRunNoOrg) && !createOpenedRef.current) {
:159    setIsCreateOpen(true);
:276  <CreateWorkspaceDialog  open={isCreateOpen} …

The viewport centre resolves to the Radix DialogOverlay, and body carries pointer-events: none from Radix's DismissableLayer — which is why even a full elementsFromPoint stack loses the app. At every uncovered sample #root is fully rendered: 2 children, 1280x720, 196 characters of text.

The card's headline number does not survive measurement

The decisive result is not the cause, it is the scaling. The "uncovered span" tracks the trailing sample window 1:1:

settle window	measured span
500 ms	~507-520 ms
1500 ms	~1747 ms
3000 ms	~2841-3019 ms

So ~453 ms is not the width of a window — it is the width of the ruler. The state is steady and lasts exactly as long as the modal is open. That makes the card's framing ("the widest window in the codebase", comparable to objectui#6378's 41-147 ms) unsound: those are bounded transients, this is not a transient at all.

Two further readings point the same way. Zero white frames across 391 post-mount frames, with the minimum colour channel inside every uncovered window measured at 0 — the modal's 80%-black overlay, i.e. the opposite of a white flash. And under 20x CPU throttling (objectui#6378's own profile) the reading gets weaker, 0-8 samples against a median of 21, which is backwards for a timing race and exactly right for a steady state being sampled fewer times.

Reproduction rate: 20/20 boots, median 21 samples / 446 ms — the card's 22 / ~453 ms is the median, so the original observation was accurate. It was the interpretation that was wrong, not the number.

The instrument was shown able to red and to green

Four control arms on a signed-out boot, which is what separates "the app is fine" from "the probe is broken":

1. untouched — reads covered (0 uncovered, 0 white frames) ✅
2. #root emptied, splash removed — reads uncovered, 6/34 white frames, min channel 246 ✅ the probe does catch a real blank viewport
3. body-level overlay, app still hit-testable — top-element rule says uncovered, full-stack rule says covered
4. body-level overlay + body { pointer-events: none } (the Radix modal shape) — both DOM rules call a fully visible app empty

Arms 3 and 4 reproduce this card's exact signature deliberately, with no defect present. That is the refutation in its cleanest form.

What was NOT measured, stated plainly

A real non-mocked boot (the mocked endpoint set from #6569 was in place throughout; that the dialog opens from session state rather than the fixture is read from source, which is the independent check above); the sibling "member of orgs, none active" scenario; other body-level portals (toasts, popovers, command palette). And "zero white frames" is a bound rather than a proof, since the screencast emits on compositor swaps.

Outcome

Closed not_planned — a measured absence of a defect, with the evidence on the card so a maintainer can veto and reopen at zero cost. No PR, no branch merged; a premise-first stop with this much evidence is the intended result of that dispatch shape, not a failure of it.

The reusable half was filed separately as #6578: the boot-continuity coverage rule reads an open modal as a blank viewport, in both its top-element and full-stack forms — the false-positive direction of the same instrument whose false-negative direction #6569 recorded. Only the pixel ledger tells them apart. That card is filed unassigned and ungraded for triage; it lands in the e2e gate rather than in this lane.
