WalkthroughThe pull request moves Playground navigation into the top bar and mobile account menu, consolidates chat and comparison history, changes comparison setup to require Model B, and refreshes the Playground layout and shared UI components. ChangesPlayground experience

Center and cap the composer, align Tools and model hover areas, and correct history dialog spacing. Reuse shared chips, disclosure, copy, and popover controls and restore a saved conversation's model when loading it. Co-Authored-By: GPT-6 <noreply@anthropic.com>

Self-review before this leaves draft. CodeRabbit skipped the PR ("Draft PR not reviewed"), so nothing external has read it yet.
Three correctness or accessibility items, four design-system items, and one about the comments the diff removes. Popover's nested-trigger fix and the label="Copy response" to label="response" correction (which was producing an accessible name of "Copy Copy response") are both right and both covered by new tests.
Reviewed by Claude Opus 5.
Align accessible control names, disambiguate shared model labels, reuse PageIntro and Section layouts, and keep chat widths in one constant. Separate inline action styling from filter density and preserve the component rationale. Co-Authored-By: GPT-6 <noreply@anthropic.com>

Self-review by Claude Opus 5. Five findings, none blocking the design direction: one dead prop on a shared component, one hand-rolled control border, one heading nested inside a list item, one over-wide union, and one rationale comment that lost the fact it existed to record.
Drop the unused CopyButton label mode, give the History control a label so it takes the ghost edge instead of a wrapper drawing one around an icon-only button, lift the date heading out of its first list item, narrow the composer's missing-model prop to the panel that can be missing, and restore the reason both comparison columns start empty. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
…inks A worktree puts symlinks at .venv and web/node_modules. The ignore patterns carried a trailing slash, so each matched a directory only and the symlinks were untracked by accident rather than by rule; a commit that staged everything picked them up. CI then checked them out and both uv and pnpm refused to create the paths that already existed. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
The two panels stream independently, so `findAllByText` resolved on whichever answered first and the length was then read one short. It held locally and failed under CI load. Waiting on the count retries until both have answered, which is what the assertion was always about. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
That PR fixes it in both ignore files with its own note, so editing the same line here would only hand whichever merges second a conflict. `.venv` stays, because #1216 does not cover it and the symlink there is what broke the serving and e2e installs.

Two findings land on files this PR did not touch, so they are here rather than inline:
web/e2e/screenshots/authenticated.spec.ts:26still gates the/playgroundcapture onheading: /what can i help with/i. That greeting is now "Try a prompt." and the page grew aPageIntrotitle, soopen()times out and the playground baseline never renders. The comment above the entry ("the one page in this matrix with no page title") is stale for the same reason;heading: /playground/iis now the right regex.docs/dashboard.md:88still lists Playground in the workspace sidebar ("Playground, Models, and Routing").web/AGENTS.mdand.github/instructions/frontend-standards.instructions.mdwere updated for the move; this one was missed.

Inline comments:
In `@web/src/design-system/overlays/Popover.stories.tsx`:
- Around line 99-101: Expose an accessible-label prop on Popover and apply it
through the HeroPopover.Dialog naming path, then pass “History” from both the
History story and the production PlaygroundHistory popover so each dialog has an
accessible name. Keep the existing visual History heading unchanged.
In `@web/src/features/playground/ModelSelect.tsx`:
- Around line 57-63: Update the selectedLabel fallback in ModelSelect so an
unknown selected key displays the raw value instead of an empty label; preserve
the existing ambiguous-label behavior and use the empty placeholder only when no
value is selected.
In `@web/src/features/playground/PlaygroundConversation.tsx`:
- Around line 72-76: Update the model-change handler to clear the selected
panel’s turns whenever its model changes, and also clear panel B’s turns when
the collision branch resets panelB.model. Keep the existing model-selection
behavior while ensuring no stale transcript is retained for an unselected or
newly selected model.

Restore a saved conversation's model through the catalog guard, so a transcript that outlived its model no longer leaves the picker blank while Send still dispatches. Drop a comparison panel's turns whenever its model changes, including the panel cleared by a collision, so stale answers cannot be sent to a model that did not produce them. Give Popover a required accessible name, narrow its trigger to an element and state that it must be a react-aria pressable, and record both rules in design/overlays.md. Move the history date grouping into shared format helpers and read the clock once per render pass. Reach the field variables through an .otari-composer place rather than arbitrary classes. Use IconButton for the four hand-rolled icon buttons, name the save control after its visible label, and put prose on the caption role rather than the identifier one. Revert the .gitignore change, which belongs with #1216 rather than here. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
