💭 This PR removes tests, but the check is scoped to UI consistency, not test coverage. I'm noting these deleted tests actually guard primitive geometry and interaction contracts—button, command, menu components, plus disabled-state tooltip behavior—which feels like more than a trivial visual migration. The rules explicitly call out button geometry tokens, control-icon-color indirection, and tooltip trigger interactivity on disabled controls as contracts to protect — and deleting their tests removes that guardrail even without a code change. Since no other files were modified, the components and their fragile behaviors still exist, so I want to verify these components directly to confirm the deleted tests were genuinely guarding non-obvious contracts worth flagging.

1. browse_code — apps/web/src/components/**/*.test.tsx

2. browse_code — apps/web/src/components/chat/PanelLayoutControls.tsx

💭 The wrapper span pattern for TooltipTrigger exists specifically so disabled buttons still show tooltips, and deleting that test removes protection against regressing this fragile behavior. I need to check whether removing a test counts as a violation under the rule requiring focused tests for changes to composition behavior, prop forwarding, or similar logic. The button test also verified icon color routes through a CSS variable, matching the guidance to watch for shared primitive color indirection. This looks like a case where meaningful regression tests are being pruned, so I want to check git history to see if these tests were added deliberately alongside bug fixes, which would strengthen flagging their removal.

3. git_tools — apps/web/src/components/chat/PanelLayoutControls.test.tsx

4. git_tools — apps/web/src/components/ui/button.test.tsx

💭 The button test extension traces back to the appearance contrast control feature, guarding the deliberate choice to use an opaque semantic icon color rather than opacity-80. Removing that test would strip away this accessibility safeguard, and I'm noticing similar geometry contracts protected in the command and menu tests. Since selector ownership matters here — whether they live on the wrapper or the input — and the command.tsx file has comments confirming selectors must stay on the wrapper, this contract seems deliberate rather than incidental. I also want to check whether PreviewChromeRow's test is truly behavioral, verifying the full URL displays when unfocused, rather than just checking static markup. Since the check scope is limited to apps/web/src files, I can rule out the mobile typography test deletion. I'm leaning toward flagging button.test.tsx for the control-icon-color rule, PanelLayoutControls.test.tsx for the disabled-tooltip interaction semantics, and command.test.tsx for the fragile selector ownership contract — while I still need to verify whether PreviewChromeRow and menu.test.tsx warrant flagging too, since they might be closer to static markup checks.

5. git_tools — command-shell-inset

6. git_tools — value=|focus|url

💭 I'm weighing whether removing these tests actually falls under "UI Consistency" scope—strictly the rules focus on behavior changes, prop forwarding, and state logic, not test deletion. But even if it's not a direct rule violation, stripping away tests that guard control-icon-color indirection, disabled-tooltip interactivity, and selector ownership creates real regression risk. That said, the check defaults to failure unless there's an active reason to mark it clean, which suggests I should lean toward flagging something here rather than dismissing it. Looking closer, some of the deleted tests (like the menu and command class-string assertions) seem like brittle presentation snapshots that are reasonable to prune, while others—like the disabled-tooltip span wrapper pattern and the PreviewChromeRow unfocused-value assertion—guard genuine accessibility and state behavior contracts that I think are worth flagging. I'll focus my inline comments on the strongest cases: PanelLayoutControls (accessibility pattern), button.test.tsx (contrast icon-color contract), and possibly command.test.tsx (selector ownership, which this check explicitly cares about). I want to keep it to just a few comments rather than flagging everything, prioritizing the accessibility and contract-guarding tests over pure presentation snapshots. For deleted files, I'll place inline comments on the LEFT side using the original line numbers since the whole file shows as removed. Since these are deleted files, there's no diff to suggest fixing—restoring the file is the only real option, so I'll note that. For line numbers I need to use the LEFT side pointing at the original file's lines; for button.test.tsx that means anchoring around lines 8-19 covering the icon color test, using a multi-line comment with start_line and start_side LEFT. I confirm the PR only contains test deletions, nothing else, so I can move to drafting the actual review comments now, starting with PanelLayoutControls.test.tsx around lines 6-27 on the LEFT side. For that first comment, I want to flag that both panel toggles rely on a TooltipTrigger wrapper so tooltips still fire even when the underlying Toggle is disabled — deleting this test risks a silent regression if someone inlines the trigger directly onto the Toggle like RightPanelMaximizeControl does, losing the "unavailable" explanation for keyboard/pointer users. I'll suggest keeping this test or folding it into a shared tooltip-on-disabled test rather than removing coverage outright. Next, for button.test.tsx, I'm noting it covers the --control-icon-color indirection tied to the appearance contrast control work, verifying icon tone comes from a semantic token rather than hardcoded opacity, plus checking square icon-xs geometry across breakpoints — I'll suggest preserving at least the icon-color assertions. Then moving into command.test.tsx, I'm starting to think through what that test verifies regarding element selection. I'm now examining which element owns the --command-shell-inset selectors — the wrapper keeps the start-addon inset while the responsive padding lives on AutocompleteInput, and these are order/scope-sensitive arbitrary variants worth flagging. I also note PreviewChromeRow.test.tsx asserts the unfocused address bar renders the full URL, which is a real state-transition contract worth keeping. Overall I'm leaning toward failing the check, with a brief summary noting the cross-cutting pattern of net removal of behavioral guardrails, keeping the verdict short since each finding is already inline.

7. modify_pr — This PR only deletes tests. Four of the removed web suites are not static presentation snapshots — they pin interaction/state/selector-ownership contracts that this codebase has regressed on before (disabled-control tooltips, the contrast-era --control-icon-color indirection, command inset selector ownership, unfocused address-bar value). Removing them leaves those contracts unguarded with no replacement coverage in the PR. apps/web/src/components/ui/menu.test.tsx is a pure class-string snapshot and is reasonable to prune.
