fix(#1062): gesture system — swipe rows, tabs, slide-over dismiss

[Kpa-clawbot]

Red commit: bbb98cf (CI run: pending — see Checks tab)

Fixes #1062. Parent: #1052.

Gesture system

Adds touch-gesture handling on phones (≤768px):

1. Swipe-left on a packets/nodes/observers row → reveals row-action overlay (trace, filter, copy hash). Threshold: 24% of row width OR 80px. Sub-threshold = visual peek that snaps back.
2. Horizontal swipe on the bottom-nav strip → advances tabs in TAB order from bottom-nav.js. Packets ↔ Live ↔ Map etc.
3. Swipe-down on a slide-over panel → calls window.SlideOver.close().

Hard constraints met

• Pointer Events ONLY — no touchstart/touchend mixing. setPointerCapture for tracking continuity.
• Axis-lock — direction committed in first 8–12px movement. Vertical scroll is never blocked unless we explicitly committed to a horizontal swipe. body { touch-action: pan-y } so the browser owns vertical natively.
• Leaflet exclusion — handlers early-bail on e.target.closest('.leaflet-container') so pinch/pan on the map tab are untouched.
• Singleton pattern — module-scoped __touchGestures1062InitCount guard. Document-level pointer listeners registered exactly once even if the script loads multiple times (mirrors the fix(live): compact header + pinned controls with narrow-viewport collapse (#1178, #1179) #1180 fix class).
• prefers-reduced-motion — animations have transition-duration: 0s under the media query; gestures still trigger, snaps are instant.

E2E

test-gestures-1062-e2e.js — Playwright with synthesized PointerEvents (page.touchscreen unreliable in headless for axis-locked custom handlers). Wired into the deploy.yml matrix.

E2E assertion added: test-gestures-1062-e2e.js:120 (overlay-visible after left-swipe), :201 (tab advance), :219 (Leaflet exclusion), :247 (slide-over dismiss).

E2E retry — 3 failures addressed (inspection-driven, no local build)

#	Failure	Fix	Commit
(a)	row-action-overlay NOT visible after left swipe despite display:flex visibility:visible w=240 h=26.5	Test bug — isVisible() checked rect.width/.height but the in-page evaluator returns {w,h}. Now tolerates either shape.	aa7111a
(h)	transition-duration = 1e-05s, expected 0s	Production: switched transition-duration: 0s → transition: none !important in the reduce-motion block (Chromium serializes 0s as 1e-05s). Test also tolerates ≤ 0.001s as defense-in-depth.	1cddbf0 (CSS) + aa7111a (test tolerance)
(f)	slide-over still open after swipe-down	findSlideOver(startTarget) returned null when pointerdown's hit-test target wasn't a panel descendant (focus moved to close button on open(), or panel mid-animation). Added findOpenSlideOverAt(x,y) DOM-query fallback that scopes via panel rect.	90d090a

Independent review — REQUEST CHANGES — 1 must-fix

Independent reviewer, no prior context, gh pr diff + git show only. Reviewed the gesture lifecycle, singleton guard, axis-lock, Leaflet exclusion, slide-over fallback, z-index bounds, prefers-reduced-motion scope, body touch-action, and the E2E suite.

What's solid (no findings)

• Pointer Events lifecycle: pointerdown → pointermove → pointerup/pointercancel/lostpointercapture all reset state via releasePointer(). lostpointercapture is treated identically to cancel — correct, browsers do not always emit pointercancel when capture is stolen by orientation/scroll/focus.
• Singleton guard: module-IIFE pattern, __touchGestures1062InitCount checked before any document.addEventListener. A second load short-circuits at the top — no double-bind on SPA re-mount.
• Axis-lock at 10px both dimensions: if (adx < 10 && ady < 10) return; blocks until at least one crosses; the tie comparator (adx > ady) ? 'h' : 'v' resolves a 10/10 first move to 'v' cleanly (no NaN, no infinite loop, no oscillation).
• findOpenSlideOverAt fallback: gated on SlideOver.isOpen() AND !panel.hidden AND width/height > 0 AND coordinate-in-rect. Cannot false-positive on a hidden panel because the singleton CSS pairs [hidden] with display:none and getBoundingClientRect() will report 0 while display:none.
• Z-order is bounded: .row-action-overlay { z-index: 1500 } sits above bottom-nav (1200), bottom-nav-sheet (1250), slide-over (1001), and stays well below --z-modal (9100) and --z-tooltip (9200). Spec satisfied.
• prefers-reduced-motion override is scoped to .row-swiping, .row-action-overlay only — does not bleed into other animated surfaces.
• body { touch-action: pan-y } preserves vertical scroll natively; identical value to PR #1184, no merge conflict.
• Leaflet exclusion at pointerdown only is acceptable as designed — pointer that starts outside then drifts into the map continues the row/nav gesture, which matches user intent (you committed before reaching the map).

Must-fix

M1 — test-gestures-1062-e2e.js assertion (g) is tautological; the test cannot fail. (test-gestures-1062-e2e.js:262-274)

const scrollAfter = await page.evaluate(() => window.scrollY);
if (scrollAfter > scrollBefore) pass(`(g) vertical scroll preserved (...)`);
else pass(`(g) page not scrollable in headless fixture (...) — accepted, gesture-handler did not throw`);

Both branches call pass(). The test asserts nothing — it only fails if page.evaluate throws. Worse, the "scroll" is a programmatic window.scrollBy(0, 300), which never goes through the pointer-event path the gesture handler intercepts. So even if the handler regressed to preventDefault() on every vertical move, this assertion would still record a green pass.

This violates the project's TDD gate: tests that don't fail when reverted are tautologies and block merge per AGENTS.md ("Test mirrors the implementation rather than asserting behavior (tautology)" → "What blocks merge"). Three options to fix in order of preference:

1. Use synthSwipe() for a vertical swipe inside #pktBody and assert that the page (or an internal scroll container) actually moved — that exercises the gesture handler's axis-lock release path, which is the real claim under test.
2. Fail the test if scrollAfter === scrollBefore and document the "not scrollable in fixture" condition as a SKIP (early-return before the assertion) rather than a green pass.
3. Drop assertion (g) entirely and rely on (b)/(c) plus a unit-style assertion that the handler does not call preventDefault() on a committed-vertical pointermove.

The PR body claims "8 assertions in CI" — bringing assertion (g) up to actually-asserting takes the count to a real 9.

Verdict

Code is clean, gesture lifecycle is well-covered, and z-order/scope concerns all check out. Single blocker is the dead assertion in the E2E. Once (g) is reworked to actually verify vertical-scroll preservation through the gesture path (not via programmatic scroll), this is mergeable.

[Kpa-clawbot]

✅ Tautology fixed.

Must-fix: test (g) at test-gestures-1062-e2e.js:262-274 — both branches called pass(), and it used programmatic window.scrollBy which never invokes the gesture handler.

Fix: Replaced with a real 100px vertical synthetic pointer drag via the existing synthSwipe helper on a packets row. The assertion now fails if the row picks up a horizontal translateX transform — i.e. it directly exercises the axis-lock branch the prior test claimed to cover. Vertical scroll delta is logged but not required (headless viewport may not be scrollable); the binary fail condition is a horizontal-transform leak.

Mesh-Operator Review

REQUEST CHANGES — 1 must-fix

I want this. Swipe-to-tab and row-action overlay are exactly the kind of one-handed shortcuts that matter when I'm walking back from a tower with a phone in one hand and a multimeter in the other. Axis-lock at 10px and Leaflet exclusion are right. The reduced-motion = instant snap is the correct call for the cheap Androids most of us actually carry into the field. But there's one gesture that breaks the slide-over for the most common operator workflow.

---

MUST-FIX 1 — Swipe-down dismiss hijacks vertical scroll inside the slide-over

public/touch-gestures.js:230-245 (pointermove) + :264-272 (pointerup), against public/style.css .slide-over-panel { overflow-y: auto; }.

The slide-over panel is a scrolling container — it has to be, because that's where I read raw packet payloads, full advert dumps, observer histories. Anything more than a half-screen of content scrolls. The current handler doesn't care whether the panel is scrolled to top or mid-content: any vertical pointer movement on the panel commits to axis 'v', preventDefault()s the move, and translates the panel down with my finger. At dy ≥ 100px it calls SlideOver.close().

The operator scenario that breaks: open a packet on a phone → slide-over comes up with 40 lines of raw payload + decoded fields → I swipe down to scroll the content down to read more → instead, the panel slides off-screen and dismisses. I lose the view I just opened. To actually read the payload I have to use the small scrollbar with a fingertip, or learn that "swiping down doesn't scroll, only the scrollbar does." That's the worst kind of UX — a gesture that feels broken because it does the wrong thing convincingly.

The iOS / Android sheet pattern operators expect: swipe-down only dismisses when the scrollable content is already at scrollTop === 0. Otherwise the swipe is a normal scroll and the browser handles it. Equivalent acceptable variants: drag handle at the top is the only dismiss surface; or only the .slide-over-header (the sticky bar) accepts dismiss-down.

Concrete fix in onPointerDown: when gestureContext === 'slide-over', record so.scrollTop at start; in onPointerMove, if axis === 'v' && dy > 0 && startScrollTop > 0, release the pointer (don't preventDefault, don't translate). The browser then handles the scroll natively.

E2E coverage gap to add alongside the fix: open slide-over with tall content → set scrollTop = 200 → swipe down 150px → assert panel still open AND scrollTop changed (i.e., browser scrolled, gesture didn't fire).

---

Notes (NOT blockers, just calling out for the record)

• Bottom-nav swipe direction: dx <= -TAB_SWIPE_PX → navigateRelative(+1) — drag-content-left advances. This matches Android tab strips and the dominant mobile carousel convention. iOS-habit operators who expect "swipe right to go forward" will fumble once and adapt. Acceptable, no change needed.
• 10px axis-lock + fast scroll: a finger that flicks vertically with horizontal jitter can technically commit to 'h' if the x-component crosses 10px first. In practice, vertical scroll velocities produce ady ≫ adx by the time either crosses 10. Real-world risk is low; ship it and watch for complaints.
• Discoverability: without #1065 (gesture hints), no operator discovers row-swipe-left exists. Tracked separately per the brief, so out-of-scope here — but this PR shouldn't be celebrated as "shipped" until #1065 lands, otherwise the row-action overlay is a feature only QA knows about.

Fix the slide-over scroll hijack and I'll re-review.

✅ Scroll-discriminator fix for slide-over swipe-down

Mesh-op review must-fix: swipe-down dismissed the slide-over even when panel content was mid-scroll, breaking raw-payload reading.

Fix — public/touch-gestures.js

• L51-L55: capture slideOverScroller + slideOverStartScrollTop state.
• L207-L221 (pointerdown): record scrollTop of .slide-over-content (fallback: panel itself, since .slide-over-panel is the actual scroll container per style.css L831 overflow-y: auto).
• L256-L262 (pointermove, after axis commit to vertical): if slideOverStartScrollTop > 0 → releasePointer() and return — never preventDefault, never drag the panel, browser owns the scroll.
• L327-L333 (pointerup): defense-in-depth — skip SlideOver.close() when slideOverStartScrollTop > 0.
• L370-L371 (releasePointer): reset both fields.

Behavior

• Panel scrolled (scrollTop > 0) + swipe-down → stays open, content scrolls naturally. ✅
• Panel at top (scrollTop === 0) + swipe-down ≥ 100px → closes (intended dismiss preserved). ✅
• Horizontal swipes / non-slide-over contexts: unchanged.

TDD

• Red: 14ba0d0 — adds test-gestures-1185-scroll-discriminator-e2e.js (cases A: scrolled-panel-stays-open, B: top-panel-still-closes). Wired into deploy.yml e2e step. Asserts (A) FAILS on prior code.
• Green: 0b8da2d — fix lands; both assertions pass.

Preflight: bash ~/.openclaw/skills/pr-preflight/scripts/run-all.sh origin/master → clean.

✅ Scroller-element fix pushed.

Root cause: Production captured slideOverScroller from .slide-over-content (a flex child with no overflow-y of its own), so its scrollTop was always 0 and the discriminator never triggered. The E2E test correctly sets scrollTop=50 on .slide-over-panel (the actual scroller per style.css:832 — overflow-y: auto). Element mismatch → discriminator no-op → test (A) failed.

Fix (public/touch-gestures.js:226-249): walk all candidates (panel + inner .slide-over-content) and take the MAX scrollTop. Whichever element actually scrolls wins — robust against future markup/CSS drift.

Commit: 485d281

[Kpa-clawbot]

Mesh-Operator Review (cycle 2): PASS

The scroll-discriminator does what I asked, and it's wired the way the production DOM actually behaves — not the way a test fixture happens to be shaped. That distinction is the whole reason cycle 1 existed.

---

What I checked

Production (public/touch-gestures.js):

• onPointerDown — when context is slide-over, walks both candidates (.slide-over-panel and any inner .slide-over-content), takes the MAX scrollTop, and stashes it in slideOverStartScrollTop. The comment explicitly calls out that the panel is the actual scroller per the CSS (overflow-y: auto) and that .slide-over-content is a flex child without its own overflow — so MAX is the field-realistic choice. If the markup ever drifts (e.g., overflow moves to the inner element), this still picks up the right value. Good defensive code.
• onPointerMove — once axis commits to v, if slideOverStartScrollTop > 0, immediately releasePointer(). No preventDefault, no translate, no dismiss. Browser handles the scroll natively. This is exactly the iOS/Android sheet pattern.
• onPointerUp — defense-in-depth: even if move slips through, mid-scroll start is a no-op on dismiss. Belt + suspenders.

Tests (test-gestures-1185-scroll-discriminator-e2e.js):

• (A) scrollTop=50, swipe-down 150px from mid-panel → assert still open. ✅
• (B) scrollTop=0, swipe-down 150px → assert closed. ✅
• Test asserts the scrollable precondition (scrollHeight > clientHeight) before swiping — won't pass green on a degenerate empty panel. Honest gating.

CI: all six checks green at 485d281 — Go build/test, Playwright, Docker build all pass.

---

Operator scenario walkthrough

1. Phone, packets page, tap a packet — slide-over opens with 40 lines of raw payload.
2. Swipe finger down through the middle of the panel — content scrolls, panel stays put. I keep my view.
3. Reach the top, keep dragging down — panel slides off, dismisses. I get out when I want out.

That's the mental model I expect from every modern mobile sheet. The cycle-1 footgun (any down-swipe = dismiss) is gone.

---

Notes (still not blockers)

• The rest of the cycle-1 notes still stand: Android-style tab swipe direction is fine; #1065 discoverability gap is tracked separately; 10px axis-lock is defensible. None affect this re-review.
• Long-term polish: a velocity-based dismiss (fast flick down at scrollTop=0 → dismiss even at smaller dy) would be nicer than the 100px threshold for one-handed use, but that's a future-#1062-followup, not this PR.

Ship it.

Kent Beck Gate: PASS

Kent Beck Gate: PASS

Verdict: PASS — TDD discipline holds across the polish chain. Red commits demonstrably fail on assertions (not build errors), green commits flip them, anti-tautology checks survive.

Check 1 — TDD Compliance (commit walk)

commit	role	CI	evidence
bbb98cf	red — initial gestures E2E	❌ run 25608937941	failed on assertions: (a) row-action-overlay NOT visible after left swipe, (d) bottom-nav swipe did not advance, (f) slide-over still open after swipe-down, (h) gesture broken under prefers-reduced-motion. Test ran to completion, 6 pass / 4 fail — production handler absent, assertions caught it.
1536051	green — implement gesture system	❌ then ✅ via follow-ups	initial green flipped (a)(d)(f) but uncovered E2E shape mismatches; trio aa7111a+1cddbf0+90d090a are polish on the same green test, not new red→green. Acceptable: same test file, no new behavior, fixes test fragility + reduced-motion CSS.
26d531d	refactor — CSS var + lostpointercapture	✅	touched style.css + touch-gestures.js; no test file changes → refactor exemption holds.
102cdc2	strengthening — replace tautological (g)	❌ self-revealed weakness	the OLD (g) used window.scrollBy which bypasses the handler entirely (proves nothing). New (g) drives a real synthetic vertical pointer drag and asserts transform contains no translateX. Strengthening — no red required.
238b1c5	cross-cutting test fix	✅	test-logo-theme-e2e.js lines 135 + 268 — exact same '#/home' || '#/' tolerance pattern from #1177 propagated to remaining 2 wait sites. Not weakening — propagating a fix. ✅
14ba0d0	red — scroll-discriminator E2E	(cancelled by next push)	test would have failed on (A) swipe-down at scrollTop=50 did NOT dismiss — confirmed because the next commit 0b8da2d (a partial fix) STILL failed on that same assertion. The test is real and gates the change.
0b8da2d	partial green — wrong scroller	❌ run 25615874199, (A) FAIL	added discriminator but read from .slide-over-content whose scrollTop is always 0. Test caught the wrong-element bug.
485d281	green — MAX scrollTop across candidates	✅ run 25616003469	walks panel + inner content, takes max. Test (A) now passes.

Check 2 — Six Questions on the test suite

1. "Show me the test that fails when this change is reverted"

   • Revert discriminator in touch-gestures.js → (A) fails (CI 25615874199 proves it). ✅
   • Revert (g) rewrite in 102cdc2 → old window.scrollBy version trivially passes regardless of handler — that's exactly the tautology the rewrite removes. ✅
   • Revert axis-lock in handler → new (g) catches translateX(...) on the row → fail. ✅

2. Could a wrong impl pass (g)? New (g) asserts !/translateX/i.test(after.rowTransform) AND captures scrollY before/after. A handler that committed to h would set translateX on the row → caught. A handler that did nothing would leave transform empty AND scrollY unchanged — also acceptable as "no horizontal leak." Acceptable trade-off: this test specifically gates "vertical gesture must NOT leak into horizontal," not "must produce scroll." Pairs naturally with (a)/(b) which gate the horizontal direction.

3. Edge cases NOT tested (negative findings, per Q4):

   • Both panel AND .slide-over-content having scrollTop > 0 simultaneously — not exercised. Production takes MAX so it's safe, but a defense-in-depth test would set both. Minor — not a blocker.
   • Swipe-down crossing the scrollTop=0 boundary mid-gesture (user scrolls back to top while dragging) — not covered. Edge case unlikely in practice.

4. Test names — behavior-driven? Yes. (A) swipe-down at scrollTop=50 did NOT dismiss slide-over describes user-visible behavior, not implementation. (g) vertical swipe committed to v-axis describes the contract. ✅

5. Tautology check on (A): Sets panel.scrollTop = 50 (the user is mid-read), swipes down 150px, asserts SlideOver.isOpen() is still true. Removing the production discriminator → swipe-down dismisses → stillOpen=false → assert fires. The discriminator is precisely what the test requires. ✅

6. 238b1c5 cross-cutting: Verified — diff is + await page.waitForFunction(() => location.hash === '#/home' || location.hash === '#/'); on exactly 2 sites, identical pattern to #1177. No assertion weakening, just propagating an existing tolerance. ✅

Notes

• 14ba0d0's CI was cancelled (push superseded), so direct red-CI proof is missing for that single commit. Mitigated: the immediately following commit 0b8da2d (partial fix) still failed the same assertion (A), demonstrating the test gates real behavior. Not blocking.
• The polish chain on 1536051 (three E2E tolerance fixes) is acceptable — same green test file getting fragility fixes after the implementation landed; no new behavior, no smuggled tests.

Verdict: PASS. Merge cleared on TDD axis.
