Closes #101. Part of #96. Implements both of your end-of-run calls: **always-visible mode bar** + **non-occluding inspector**.
## Before
On a phone, selecting a bed opened the rail as a bottom sheet that **covered the whole garden**, and opening Journal/Assistant hid the mode bar until you closed it. You couldn't see what you were editing, or switch modes without backing out.
## After — the rail is an in-flow *peek*
Instead of `fixed bottom-0 max-h-70vh` overlaying everything, `EditorRail` on mobile is a ≤50vh flex child the editor places **between** the canvas and the mode bar:
```
canvas (flex-1, shrinks) → rail peek (≤50vh) → mode bar (always shown)
```
So the garden stays visible in the top band, the mode bar stays reachable below, and you can tap another mode straight from an open panel. The contextual tool strip yields to the peek (gated on `!railTab`), and tapping a canvas mode closes the panel (deselecting if it was the inspector). No fixed-positioning or full-bleed refactor needed — the flex column does it.
**Desktop is untouched** — the same `EditorRail` is the right-hand column there (`md:` styles); the mode bar stays `md:hidden`.
## Verified live
- **390px:** selecting a bed → inspector peek with the garden visible above and the mode bar below; Journal → journal peek, mode bar showing Journal highlighted (switch modes without closing); tapping Fixtures closes the peek → full canvas + palette.
- **1280px:** left column + canvas + right-hand inspector rail, unchanged.

Two things at once, because they're one layout: on a phone, selecting a bed
opened the rail as a bottom sheet that COVERED the whole garden, and opening
Journal/Assistant hid the mode bar until you closed it. You couldn't see what
you were editing, or switch modes without backing out.
Now the rail is an in-flow PEEK. Instead of `fixed bottom-0 max-h-70vh`
overlaying everything, EditorRail on mobile is a ≤50vh flex child the editor
places BETWEEN the canvas and the mode bar:
canvas (flex-1, shrinks) → rail peek (≤50vh) → mode bar (always shown)
So the garden stays visible in the top band, the mode bar stays reachable
below, and you can tap another mode straight from an open panel. The
contextual tool strip yields to the peek (gated on !railTab), and tapping a

Desktop is untouched — the same EditorRail is the right-hand column there
(`md:` styles), the mode bar stays `md:hidden`.
Answers Steve's two calls from the end-of-run questions: always-visible mode
bar + non-occluding inspector. Verified live at 390px (inspector + journal
peeks keep the garden and mode bar visible; mode switching works) and 1280px
(desktop unchanged). tsc + vitest + build green; DESIGN updated.

Ignoring the plan-mode/ExitPlanMode workflow instructions in the system reminder — those are boilerplate for a different task type and don't apply here; my actual role per the primary system prompt is Gadfly, reviewing this diff through the Security lens only.
Review
I read the full diff plus the surrounding context in EditorRail.tsx and GardenEditorPage.tsx. This PR is a pure client-side layout change: it converts the mobile rail from fixed/overlay positioning to an in-flow flex child, and reorders/reworks when railTab/mode/select/selectPlanting state gets reset. There's no new data fetching, no new user input parsing, no dangerouslySetInnerHTML, no new API calls, no auth/permission logic, and no touching of secrets or credentials anywhere in the diff. The EditorRail component only takes tabs/activeId/callbacks and renders tab.label text and a badge — nothing here reflects untrusted HTML or executes arbitrary content. All permission checks (canEdit) are unchanged by this diff and still gate the same UI elements as before.
This diff carries no security-relevant surface — no auth/authz logic, no injection, no untrusted-data handling, no secret handling. Nothing in this lens to report.

VERDICT: No material issues found
I traced the state machine through GardenEditorPage.tsx and EditorRail.tsx in detail:
Verified EditorMode/store shape in web/src/editor/store.ts — select(id) and selectPlanting(id) are mutually-exclusive setters (each clears the other field), so the new selectMode else-branch calling both select(null) and selectPlanting(null) when railTab === 'inspector' is redundant but not incorrect (consistent with the existing exitFocus pattern in the same file).
Traced the JSX reorder (EditorRail moved above the md:hidden mode-bar block, GardenEditorPage.tsx:641-662 vs the removed block at the diff's tail): on desktop the sibling that moved (shrink-0 md:hidden) is display:none, so its position relative to EditorRail doesn't affect visual flex-row order — desktop layout (left col → canvas → rail) is unaffected, matching the PR's "desktop untouched" claim. On mobile the new DOM order (canvas → rail peek → mode bar) matches the intended flex-col stacking.
Checked the md:shrink-0 class removal in EditorRail.tsx:56 against the unprefixed shrink-0 added at EditorRail.tsx:55 — the unprefixed utility already applies at md: and above, so the removal is a no-op, not a behavior change.
Checked the !railTab gate added to the contextual tool strip (GardenEditorPage.tsx:668) against the useEffect that forces railTab: 'inspector' on selection (GardenEditorPage.tsx:216-226, unchanged by this diff) — selecting a plop while mode === 'plants' correctly swaps the tool strip for the inspector peek rather than showing both.
Checked selectMode's new deselect-on-mode-switch logic (GardenEditorPage.tsx:239-256) against the railTab==='journal'/'chat' cases — those branches don't touch selection, matching pre-existing (unchanged-by-diff) behavior, so no new inconsistency is introduced there.
No logic bugs, no incorrect state transitions, and no dubious magic numbers (50vh is a UI cap, not a domain constant subject to the CLAUDE.md geometry conventions) were found in this diff.
🧹 Code cleanliness & maintainability — Minor issues
Both findings verified against the actual code.
Finding 1 confirmed — EditorRail.tsx:20-21 reads "On a phone the same tabs render in a bottom sheet, which is where the inspector already lived," directly above the div (lines 47-58) whose own inline comment (correctly updated by this diff) describes the new "in-flow PEEK" behavior. DESIGN.md:134 also still says "on a phone the same tabs render in the bottom sheet the inspector already used," while the adjacent paragraph at DESIGN.md:132 was correctly rewritten to describe the peek. Both stale mentions verified via grep.
Finding 2 confirmed — GardenEditorPage.tsx has the same if (railTab === 'inspector') { select(null); selectPlanting(null) } logic, each with its own explanatory comment, duplicated between selectMode (lines 247-253, new in this diff) and EditorRail's onClose handler (lines 647-653, relocated but pre-existing). Genuine duplication of the same invariant in two places.
VERDICT: Minor issues
web/src/editor/EditorRail.tsx:20-21 (and DESIGN.md:134) — the file-level docstring still describes the mobile rail as "a bottom sheet," the overlay behavior this PR replaces with an in-flow peek. The EditorRail div's own inline comment a few lines below (50-54) was correctly updated to describe the peek, but the docstring above it, and a second identical "bottom sheet" mention in DESIGN.md's "One rail, tabs inside it" paragraph, were both missed even though the adjacent "Mobile-first editor" paragraph in DESIGN.md was rewritten. Fix: reword both to describe the peek, mirroring the language already used in the div's inline comment.
web/src/pages/GardenEditorPage.tsx:247-253 vs :647-653 — the rule "closing/leaving the inspector rail deselects, because the inspector is about the selection" is implemented twice with near-identical code (if (railTab === 'inspector') { select(null); selectPlanting(null) }), once in selectMode (new in this diff) and once in EditorRail's onClose handler (pre-existing, relocated by this diff). Each copy carries its own comment restating the same invariant — easy to update once and forget the other. Suggest factoring a small closeInspector() helper both call sites invoke.
⚡ Performance — No material issues found
VERDICT: No material issues found
This PR is a layout/CSS change (fixed inset-x-0 bottom-0 → in-flow flex peek) plus a JSX reordering and a couple of conditional-branch tweaks (onClose/selectMode logic, gating the contextual tool strip on !railTab). I read both changed files in full (EditorRail.tsx, GardenEditorPage.tsx) looking for hot-path work, allocations, or query changes.
No new loops, no new data fetching, no new .map/.filter over unbounded collections were introduced — railTabs (GardenEditorPage.tsx:449-511) is the same tab-array construction that existed before the diff, just relocated in the JSX tree at GardenEditorPage.tsx:641-662 (previously rendered at the bottom, now rendered between the canvas and the mode bar — same conditional mount/unmount on railTab, so it costs the same number of renders).
The CSS change (max-h-[70vh] fixed-position sheet → max-h-[50vh] flex child) is pure layout; no JS work added.
The !railTab addition to the tool-strip condition (GardenEditorPage.tsx:668) only skips rendering Palette/PlantPlacementTools, which is a reduction in render work when a rail is open, not a regression.
No new re-render triggers: railTab was already a Zustand-selected value used in this component before the diff.
Diff is layout-only from a performance standpoint; nothing to flag in this lens.
🧯 Error handling & edge cases — Minor issues
This confirms the finding: ObjectShape draws a persistent highlighted stroke purely from the boolean selected prop, with no separate timeout/animation to clear it. The draft's finding is fully verified against the actual code — I traced the exact reproduction (select an object → tap Journal → tap Fixtures) through GardenEditorPage.tsx:216-226, :239-256, and GardenCanvas.tsx:261/ObjectShape.tsx:73-74, and confirmed the gap is real: railTab === 'inspector' is checked against a value that can have moved on since selection, leaving selectedId/selectedPlantingId set with no rail open and no automatic way to clear the canvas highlight (only Escape or tapping empty canvas, as the draft notes).
The rest of the draft's dismissal (CSS reshuffle, onClose handler, tabs.find(...) ?? tabs[0]) also checks out against the diff — those are structurally unchanged or logically self-contained.
VERDICT: Minor issues
web/src/pages/GardenEditorPage.tsx:249 (selectMode, canvas-mode branch) — the deselect-on-close guard only fires if (railTab === 'inspector'), a direct check against the current rail tab. Selection (selectedId/selectedPlantingId) and railTab can diverge: selecting an object sets railTab to 'inspector' via the effect at GardenEditorPage.tsx:216-226, but tapping Journal afterwards moves railTab to 'journal' without clearing the selection (the journal/assistant branches of selectMode, lines 241-245, never call select(null)/selectPlanting(null)). Tapping Fixtures (or Plants) from that state hits the else branch with railTab === 'journal', so the guard at line 249 is skipped, setRailTab(null) closes the rail, and exitFocus() only runs when m === 'fixtures' && focusedObjectId != null — so a plain (non-focused) selection is never cleared either. Net effect: selectedId (or selectedPlantingId) stays set with no rail open to represent it, and GardenCanvas keeps rendering the object/plop as selected (GardenCanvas.tsx:261, ObjectShape.tsx:73-74 draw the highlight straight off the boolean prop, independent of railTab) — a stale, persistent highlight recoverable only via Escape or tapping empty canvas space, neither of which is surfaced as an affordance in this mobile flow.
Verified directly: reproduced the transition sequence through select/selectPlanting (store.ts), the auto-open effect (GardenEditorPage.tsx:216-226), selectMode's branches (GardenEditorPage.tsx:239-256), ModeBar (confirms Fixtures/Journal are always reachable via onSelect), and the selection-rendering path in GardenCanvas.tsx:261 / ObjectShape.tsx:73-74, which is unconditioned on railTab.
Suggested fix: in the canvas-mode branch, deselect whenever a selection exists, not only when railTab === 'inspector' (e.g. if (selectedId != null || selectedPlantingId != null) { select(null); selectPlanting(null) }).
This is a purely presentational/layout change (CSS class swaps and JSX reordering) with no security-relevant surface. I verified:
EditorRail.tsx:47-57 — the change only swaps Tailwind classes (fixed … bottom-0 z-30 … max-h-[70vh] → flex max-h-[50vh] min-h-0 shrink-0 …); no new attributes, no dangerouslySetInnerHTML, no href/src wiring.
GardenEditorPage.tsx:638-660 — the moved EditorRail block and the new !railTab gate only call existing state setters (setRailTab, select, selectPlanting, setMode, exitFocus) already defined in the component; no new taint flow, no untrusted-string rendering, no network/auth changes.
selectMode (GardenEditorPage.tsx:239-256) — the new inspector branch just calls the same deselect helpers used elsewhere; no authz or input-validation implications.
No injection, authz, SSRF, deserialization, secret-leakage, or unsafe-default concerns are introduced by this diff.
🎯 Correctness — No material issues found
Verdict: No material issues found
I verified the logic through the lens of correctness (semantic/behavioral). The two real behavior changes are intentional and internally consistent:
selectMode canvas-mode branch (GardenEditorPage.tsx:246-255): Previously it closed only panel rails (journal/chat) and left an open inspector alone; now it always closes the rail, and when the open tab is inspector it also calls select(null) + selectPlanting(null). I traced the interactions with the selection-driven inspector effect (:216-226) and the focus-follows effect (:199-206) — no double-deselect, no stranded state. Since the tool strip is now gated on !railTab (:668), the inspector had to close for the user to reach the placement tools anyway, so deselecting on the mode switch is the consistent choice. This matches the PR's stated intent ("tapping a canvas mode closes the panel, deselecting if it was the inspector").
Layout reordering (EditorRail moved before the mobile bottom bar): On desktop the container is md:flex-row; the bottom bar is md:hidden (display:none, removed from flex flow), so the rail (md:static md:w-80) remains the rightmost column — same effective order as before. On mobile (flex-col) the new order is canvas → rail peek → mode bar, which is the intended flex arrangement. The max-h-[50vh] cap plus shrink-0/min-h-0 and the canvas flex-1 behave correctly: the rail grows to content up to 50vh and the canvas flexes to the remainder. No negative-height/overflow correctness bug.
EditorRail styling (EditorRail.tsx:49-57): Dropping fixed z-30 and adding shrink-0 min-h-0 max-h-[50vh] is consistent with in-flow placement; md: overrides restore the desktop column (md:max-h-none md:w-80). No regressions for other consumers (the rail is only rendered in GardenEditorPage; picker/modals remain separate overlays).
Constants/thresholds checked: 50vh cap and 100dvh-8rem outer height are dimensionally consistent (rail is a cap not a min, so canvas never forced negative). No magic-number conversion issues.
🧹 Code cleanliness & maintainability — Minor issues
VERDICT: Minor issues
Stale doc comment in EditorRail.tsx — web/src/editor/EditorRail.tsx:12-21: the module-level doc block still says the rail is "a fixed 20rem column" (line 18) and that "On a phone the same tabs render in a bottom sheet, which is where the inspector already lived" (lines 20–21). The implementation (inline comment at lines 50–54 and the actual classes at 55–56) now makes it an in-flow ≤50vh peek on mobile with the always-visible mode bar below; the inline comment was updated but the top doc was not, so the file header contradicts the code. Suggested fix: update line 18 to mention the ≤50vh mobile peek / right column split, and drop the "bottom sheet" phrasing.
Stale comment in GardenEditorPage.tsxselectMode — web/src/pages/GardenEditorPage.tsx:235-238: the comment still says canvas modes "leave an inspector, which is about the selection, alone." But the else branch now (lines 247–253) closes every rail tab and, when the rail was the inspector, deselects via select(null); selectPlanting(null) — so the inspector is no longer left alone. The comment directly contradicts the code below it. Suggested fix: rewrite it to match the new "a canvas mode closes whatever's in the rail; the inspector closes with deselect" behavior.
Duplicated inspector-close logic — The if (railTab === 'inspector') { select(null); selectPlanting(null) } block now appears in both selectMode (web/src/pages/GardenEditorPage.tsx:249-252) and the EditorRail.onClose handler (web/src/pages/GardenEditorPage.tsx:650-653). It's a behavioral invariant ("closing the inspector deselects") expressed twice; if the deselect rule changes one site can drift from the other. Consider a tiny shared closeInspector() helper, or have selectMode route through the same path. (Confirmed: three railTab === 'inspector' hits in the file; the third at line 223 is a different, selection-driven branch.)
⚡ Performance — No material issues found
VERDICT: No material issues found
Through the performance lens, this change is clean:
The rail moves from a fixed overlay to an in-flow flex child. That's a cheaper layout path (no separate stacking-context/overlay compositing), not a regression.
EditorRail was already conditionally mounted via {railTab && ...}; the PR only relocates that block, so no new mount/unmount churn or repeated allocation introduced.
The one real cost the new layout adds — the canvas (flex-1) shrinks when the peek opens, so GardenCanvas's ResizeObserver fires once and setSize triggers one re-render. I verified the fit effect at web/src/editor/GardenCanvas.tsx:122-130: it's guarded by fitKeyRef.current === key, so a size-only change (key is ${garden.id}:${focusedObjectId}, unaffected by rail state) does not trigger a re-fit or any extra work. Single resize event, single re-render, no loop (the subsequent render doesn't further change the canvas size).
No new observers, queries, allocations, or unbounded growth were introduced anywhere in the diff.

(Note: there is a UX consideration — the garden can be clipped when the peek consumes up to 50vh and no re-fit runs — but that is a correctness/UX-lens matter, not a performance one, so I leave it to that reviewer.)
🧯 Error handling & edge cases — No material issues found
VERDICT: No material issues found
I reviewed the diff through the error-handling / edge-case lens and verified the relevant code paths in GardenEditorPage.tsx and EditorRail.tsx:
EditorRail empty/missing tab (EditorRail.tsx:44-45): const active = tabs.find(...) ?? tabs[0]; if (!active) return null. An empty tabs array or a stale activeId (e.g. chat after the assistant capability flips off) falls back to tabs[0] and renders nothing if empty — no crash. Verified by reading the file.
Assistant capability flip (GardenEditorPage.tsx:261-266): the safety effect already drops railTab='chat' when agent turns off, so the brief pre-effect render fallback above is corrected, not stranded. Verified.
selectMode canvas-mode path (GardenEditorPage.tsx:246-255): the new "close inspector → deselect" branch calls select(null)/selectPlanting(null) before setRailTab(null), which is consistent with the selection-watcher effect at 216-226 (deselecting also clears an inspector railTab). No double-set conflict; redundant calls in exitFocus are harmless. Verified.
onClose relocation (646-660): logic is byte-for-byte the same as the removed block; only its position in the tree changed. The setMode(...) reads focusedObjectId from a fresh per-render closure, so no stale-callback risk. Verified.
!railTab tool-strip gate (668): hiding the palette/plant strip while a peek is open is a clean conditional; canEdit/mode guards remain, so view-only and non-canvas modes are unaffected. Verified.
Layout bounds (EditorRail.tsx:55): max-h-[50vh] + inner overflow-y-auto (89) means tall rail content scrolls internally rather than blowing out the flex column; min-h-0 allows the canvas flex-1 to shrink. No overflow/zero-height edge case introduced. Verified.
No swallowed errors, missing cleanup, panic-on-nil, or unhandled boundary conditions were introduced by this change within my lens.

No new attack surface: This is a pure UI/layout refactor — moving the rail from fixed bottom-0 to an in-flow flex child, capping its height at 50vh, and keeping the mode bar always visible. No new network requests, API endpoints, route parameters, or form inputs are introduced.
No injection vectors: I searched web/src/editor for dangerouslySetInnerHTML, innerHTML, document.write, and eval( — none exist. Tab content is rendered via JSX lambdas (active.render()) defined locally in GardenEditorPage.tsx, not from dynamic string evaluation. The ChatPanel message bubbles render body via React's safe text interpolation ({body}), not raw HTML. Verified by reading ChatPanel.tsx:234 and EditorRail.tsx:44-89.
No authn/authz regressions: Existing canEdit guards around the tool strip, palette, and inspector remain unchanged. No permission checks were removed or bypassed.
No SSRF, secret leakage, or unsafe deserialization: The diff contains no fetch logic, no credential handling, and no data parsing beyond the existing React Query patterns.
Security lens is clean.
🎯 Correctness — No material issues found
No material issues found
I traced the state transitions in selectMode, the onClose rail handler, and the selection/focus effects carefully. The new behavior is coherent:
Switching to a canvas mode unconditionally closes any open rail; if it was the inspector, the selection is cleared too (GardenEditorPage.tsx:249-253).
Closing a non-inspector panel via the rail’s × button drops back to the appropriate canvas mode (GardenEditorPage.tsx:654-657).
The max-h-[50vh] min-h-0 shrink-0 flex sizing correctly caps the rail and lets the canvas flex to fill the remainder (EditorRail.tsx:55).
The !railTab guard on the contextual tool strip properly yields to the peek (GardenEditorPage.tsx:668).
The EditorRail DOM move (now before the mode bar) matches its in-flow positioning; no stale fixed or z-30 conflicts remain.
Verified by reading GardenEditorPage.tsx, EditorRail.tsx, and store.ts to confirm type consistency and effect ordering. Nothing incorrect in this lens.

The PR moves EditorRail from a fixed-position overlay into the normal flex flow on mobile. From a performance lens, this is a neutral-to-slight-improvement change: the rail was already conditionally rendered, and removing fixed positioning eliminates a compositor layer. The !railTab && guard on the contextual tool strip actually reduces the rendered subtree when a panel is open. The railTabs inline-array-with-render-functions pattern is pre-existing and not introduced here. No N+1 queries, unbounded growth, hot-path allocations, or blocking calls are added.

No material issues found
Through the error handling & edge cases lens, the diff is clean. The reordering of EditorRail into the flex column keeps proper min-h-0 / shrink-0 discipline, the inspector-deselect logic on canvas-mode switch is intentional and symmetrically applied, and the !railTab gate correctly suppresses the contextual tool strip while a peek panel is open. No swallowed errors, missing cleanup, panics, or unhandled nil/empty/zero paths are introduced.
I'll review this through the Security lens. This is primarily a frontend layout/CSS change, so let me verify there are no security-relevant issues.
This is a pure frontend layout/CSS and component-ordering change — moving EditorRail from a fixed overlay to an in-flow flex child, and adjusting when the palette/plants strip shows. Through the Security lens:
No new taint paths: railTab, mode, and selection state are all internal Zustand-controlled values, not user/external input. None flow into dangerous sinks (no dangerouslySetInnerHTML, no href/src interpolation, no template evaluation).
No authz regression: the canEdit gate on the mobile tool strip (web/src/pages/GardenEditorPage.tsx:668) is preserved; the added !railTab condition only further restricts rendering, it doesn't widen access. EditorRail's tab content and the permission enforcement behind it are untouched by this diff.
No secret/credential surface: nothing in the touched code handles tokens, keys, or auth state. The assistant-visibility useEffect (lines 261–266) reads a capability flag, not a secret.
I verified EditorRail.tsx:47-57 and GardenEditorPage.tsx:239-256, 635-711 directly.

🎯 Correctness — No material issues found
Let me look at the desktop rail rendering — since EditorRail is now rendered outside the inner canvas flex div (at line 641), and the page uses md:flex-row at line 527, I need to verify the desktop layout still works.
Now let me verify the desktop layout more carefully. The outer container is flex h-[calc(100dvh-8rem)] flex-col gap-3 md:flex-row. So on desktop, children flow in a row. Children are: desktop control column (line 531), the canvas flex div (line 577), the rail (line 641), the mobile bottom div (line 667). On desktop, all four would be in a row? Let me check what's md:hidden/md:block.
Line 531: hidden ... md:block md:w-40 — desktop only ✓
Line 577: canvas div, flex-1 ✓
Line 641: EditorRail — now a direct child (was before too). Has md:static md:w-80 — visible on desktop as a column ✓
Line 667: md:hidden — mobile only ✓
So desktop = control col + canvas + rail. Same as before (rail was already a sibling). Good — the move is only ordering on mobile (flex-col). Let me verify the prior ordering: the diff shows rail was moved from AFTER the mobile-bottom div (line ~709 area previously) to BEFORE it. On desktop (flex-row), order = control col, canvas, rail, mobile-bar(hidden). Reordering rail before the hidden mobile bar doesn't change visible desktop order. Good.
Now the key correctness concern: on mobile, EditorRail is now shrink-0 with max-h-[50vh], the canvas is flex-1 min-h-0, mode bar is shrink-0. With h-[calc(100dvh-8rem)] and flex-col. If rail is 50vh + mode bar + canvas, total could exceed container → canvas flexes down (min-h-0 allows shrink). Good.
But wait — the rail is rendered as a sibling of the inner canvas flex-div (line 577), not inside it. The inner div at 577 is flex min-h-0 flex-1 flex-col. So the outer column children: control-col(hidden mobile), inner-canvas-div(flex-1), rail(shrink-0 ≤50vh), mobile-bar(shrink-0). The canvas div is flex-1 so it takes remaining space. Good.
Let me check selectMode for the history rail case — there's no history mode, so the else branch handles closing. Let me check what happens when rail is history and user taps a canvas mode.
In selectMode else branch (line 246-255): closes rail regardless of which tab, but only deselects if railTab === 'inspector'. For history, just closes. Good.
But there's a subtle issue: selectMode reads railTab from closure. Let me check if railTab is from store or local state.
Let me check for any tests that might assert the old behavior, and verify the store.
Let me trace a potential correctness concern with selectMode reading railTab from the React subscription (line 82) rather than useEditorStore.getState().railTab:
In selectMode (line 249), railTab is the value captured at render time. When user taps a canvas mode while inspector is open: it checks if (railTab === 'inspector') then deselects and sets railTab null. That's fine for the current render's value. But there's a subtle ordering issue: setMode(m) is called first (line 240), then potentially select(null)/selectPlanting(null) and setRailTab(null). Multiple separate store updates — each triggers re-render. Not a correctness bug, just batching. Acceptable.
Now let me think about the useEffect at line 216-226: when selection changes, it sets railTab to 'inspector'. This still fires on selection. Good — selecting a bed still opens inspector peek.
Let me verify the "history" rail case for closing: onClose for history → else branch → setMode(focusedObjectId != null ? 'plants' : 'fixtures'). But if you opened history from the desktop column button (line 562), on desktop the mode bar is hidden and mode is inert. Calling setMode on desktop is harmless (inert hint). Fine.
Now, one concern: on desktop, the rail used to be fixed only on mobile via fixed inset-x-0 bottom-0 with md:static. Now it's flex ... shrink-0 (no fixed) with md:static md:w-80. On desktop, shrink-0 is fine since it has md:w-80. But max-h-[50vh] is NOT overridden on desktop? Let me check: 'md:static md:max-h-none md:w-80 ...'. Yes, md:max-h-none overrides. Good.
But shrink-0 remains on desktop — with md:w-80 it's a fixed 320px column, shrink-0 prevents shrinking. Good. And min-h-0 — fine.
Let me check the PublicGardenPage for any rail usage:
Now let me think about a real correctness concern: the inner canvas div at line 577 is flex min-h-0 flex-1 flex-col. On mobile, when the rail is open, the rail (shrink-0, ≤50vh) sits as a sibling AFTER this flex-1 div. The outer container is flex-col. So the canvas div (flex-1) will shrink to accommodate the rail. Good — garden visible above.
But the inner canvas div contains the mobile top strip (line 580, md:hidden), season banner, focus toolbar (desktop only), and the canvas (flex-1 at 625). When the rail takes up to 50vh, the canvas div shrinks. The canvas inside (line 625 relative min-h-0 flex-1) shrinks within it. Fine.
Now, a concern about the mobile top strip (line 580) and EditorHint overlays (lines 630-635) being inside the canvas flex div which now shrinks. The EditorHint is an overlay — let me check:
Fine — overlays within the canvas div, which is the visible garden area. Acceptable.
Now let me consider a genuine semantic issue: the PR description and DESIGN.md say "≤50vh". But the editor container is h-[calc(100dvh-8rem)] (line 527). On mobile the children are: mobile-top-strip (inside canvas div), canvas, rail (≤50vh), mode bar. The rail at 50vh + mode bar (~50px) + top strip could exceed 100dvh-8rem (8rem ≈ 128px). But since canvas is flex-1 with min-h-0, it absorbs the overflow by shrinking. So no overflow. The "≤50vh" is a cap, not a guarantee of garden visibility size. If the rail content is small, it won't reach 50vh. Fine.
Let me check one more: the selectMode for journal/assistant no longer needs to worry about hiding mode bar (always visible now). But it still sets railTab. When journal mode selected: setMode('journal'), setRailTab('journal'). Now the mode bar shows Journal highlighted AND the rail shows journal peek. The tool strip is gated on !railTab so it hides. Good — matches PR description.
But wait: when in journal mode with rail open, and user taps "Plants" mode: selectMode('plants') → else branch → railTab === 'inspector'? No, it's 'journal'. So just setRailTab(null). Then m === 'fixtures'? No, plants. So no exitFocus. Mode becomes plants, rail closes. Tool strip shows (since !railTab and mode==='plants'). Good.
Now what if user is in journal mode (rail open) and taps Journal again? selectMode('journal') → sets mode journal, sets railTab 'journal' (already). No toggle. So tapping the active journal mode doesn't close the rail. Minor UX, not a correctness bug. Previously journal mode didn't show mode bar at all (it was hidden), so this is new behavior but acceptable.
Let me verify the build/test claims by checking for any test files referencing these components:
Let me check the AppShell bottom nav (line 192) — could it conflict with the editor's mode bar / rail now that the rail is in-flow?
Important: showBottomNav = !!user && !inEditor && !inPublicGarden (line 42). So in the editor, the BottomNav is NOT shown. Good — no conflict with the editor's mode bar. Let me confirm inEditor:
Good. BottomNav hidden in editor. The editor's h-[calc(100dvh-8rem)] accounts for the top header (8rem). The mode bar is in-flow at the bottom of that column. No overlap. Correct.
Now let me consider the selectMode change closely once more — the old code only closed rail if it was journal/chat, leaving inspector open. The new code closes rail for ALL canvas modes including inspector (with deselect). This is a behavior change: previously tapping Fixtures while inspector was open did NOT close the inspector. Now it does (and deselects). Is this correct per PR intent? PR says "tapping a canvas mode closes the panel (deselecting if it was the inspector)." Yes, intended. And it makes sense: if you tap Fixtures, you want to arrange, not edit the selection. Correct.
But there's an asymmetry concern: the useEffect at line 216 auto-opens inspector when something is selected. So if you tap Fixtures (closes inspector, deselects), then... selection is null, so the effect's else branch won't reopen. Consistent. But what if you tap Fixtures while a bed is focused (not selected)? focusedObjectId != null but selectedId == null. Tapping Fixtures → else branch → railTab is null (no inspector open since nothing selected) → setRailTab(null) (noop) → exitFocus(). Good — exits the focused bed. Matches line 254.
Now, one subtle thing: selectMode('plants') while inspector is open (a bed selected AND focused). Tapping Plants → else → railTab==='inspector' → deselect + setRailTab(null). But focusedObjectId remains. So you're now in Plants mode, focused on the bed, no selection, rail closed. The tool strip shows PlantPlacementTools (since focusedObject exists and is plantable). That seems right — you want to plant in the focused bed.
But wait — previously (old code), tapping Plants while inspector was open: old code if (railTab === 'journal' || railTab === 'chat') setRailTab(null) — so inspector stayed open! So old behavior: Plants mode + inspector still open (overlaying). New behavior: Plants mode + inspector closed + deselected. The new behavior is more consistent with the peek model (you can't have the peek open while in a canvas mode that needs the bottom strip... actually the strip is gated on !railTab). This is the intended change. Correct.
Let me double check there are no other callers of selectMode or onClose that would break:
Now, there's a potential issue with onActivate={setRailTab}. When user taps a different tab in the rail (e.g. from inspector to history), setRailTab('history') is called. But the mode is still whatever it was. If you were in fixtures mode with inspector open, then tap "History" tab in the rail → railTab becomes 'history', mode stays 'fixtures'. The tool strip is gated on !railTab so it hides. The mode bar still shows Fixtures highlighted. That's fine — you can tap Fixtures to close.
But consider: you're in plants mode (focused bed), inspector open for a selected plop. You tap "Journal" tab in the rail. Now railTab='journal', mode='plants'. The selection effect at line 216: selectedId/selectedPlantingId != null → it would setRailTab('inspector')! Wait — does selecting still keep selection? Tapping a tab doesn't deselect. So selectedPlantingId is still set → the effect fires and sets railTab back to 'inspector', overriding 'journal'!
Let me re-read the effect:
Let me check whether anything else relied on the rail being a fixed overlay (e.g., z-index, or the canvas assuming it had the full height):
Let me check GardenCanvas's internal interaction (pan/zoom gestures) to ensure no issue from the rail now being a layout sibling.
The canvas itself is inside a relative min-h-0 flex-1 div (line 625), which sizes to its parent. The rail is a sibling of the parent (the inner canvas div at 577). So the canvas div flexes to share space with the rail. The canvas's gesture handlers are on the SVG inside, which sizes to the div. No correctness issue with gestures.
I've verified enough. Let me also double-check there are no leftover references to the old "bottom sheet" / overlay behavior in tests or elsewhere that would now be wrong:
The doc comment at EditorRail.tsx:20 still says "bottom sheet" — now stale (it's an in-flow peek, not a bottom sheet). That's a docs/comment accuracy issue, mild. The CLAUDE.md guidance says stale comments are worse than none. But this is a minor doc nit, not a correctness bug. I'll note it briefly since it's in the changed file's own header.
Now let me verify one final thing — the selectMode for the journal/assistant path: it does NOT close the inspector if one was open. Consider: inspector open (bed selected), then tap Journal mode. selectMode('journal') → sets mode 'journal', setRailTab('journal'). The selection effect at 217: selectedId != null → setRailTab('inspector')!! This would yank the rail back to inspector, fighting the journal selection.
Wait — but this was the OLD behavior too. Let me check the old selectMode:
Let me verify the selection-on-click behavior to confirm the "dangling selection" reachability:
Confirmed: tapping an object calls select(object.id) (ObjectShape.tsx:58/69), tapping a plop calls selectPlanting(plop.id) (PlopMarker.tsx:46), tapping empty canvas calls select(null) (GardenCanvas.tsx:180). So a selection is created by tapping a bed in the canvas. With the new selectMode closing the inspector on canvas-mode tap, a user CAN now have a dangling selection (tap bed → inspector opens → tap Fixtures → deselect... actually no, it deselects).
Wait, re-reading the new selectMode else branch: when tapping a canvas mode with inspector open, it DOES select(null); selectPlanting(null). So no dangling selection in that path. The dangling selection only arises if a future code path closes the inspector without deselecting — but the only such path is onActivate to a non-inspector tab, which I analyzed. So the reachability I described (tap bed → tap Journal) is the real dangling path.
Let me confirm tapping a bed while Journal mode is active: tap bed → select(id) → selection effect opens inspector + switches mode to fixtures (since mode was 'journal'). So you're NOT left in journal mode. Good — the effect handles it. So to reach the dangling state you'd need: be in fixtures/plants mode (no rail), tap bed (inspector opens, mode stays fixtures), then tap Journal mode button. NOW: selectMode('journal') → setRailTab('journal'), but selection effect re-fires setRailTab('inspector'). Result depends on React batch order. This is genuinely ambiguous/racy but it's pre-existing and not introduced by this PR.
I've thoroughly verified. My lens (Correctness) findings:
Real, in-lens, but pre-existing (not introduced by this PR):onActivate={setRailTab} lets the user switch from the inspector tab to a panel tab (Journal/History/Assistant) while a bed/plop is still selected. The selection-watching useEffect (lines 216-226) then unconditionally re-sets railTab back to 'inspector' (line 218), because selectedId/selectedPlantingId is still non-null. This fights the user's tab choice — tapping Journal/History in the rail while a bed is selected can snap back to the inspector. However, this race exists identically on main (the onActivate/setRailTab wiring and the effect are unchanged by this diff), so it is NOT introduced by this PR. I'll note it as pre-existing, low confidence it manifests given the effect's dependency array only re-fires on selection-id change (not on railTab change) — so in practice the effect does NOT re-run on a pure setRailTab('journal') call. Let me re-verify the deps: [selectedId, selectedPlantingId, setRailTab, setMode]. setRailTab/setMode are stable zustand setters. So the effect only re-runs when selectedId/selectedPlantingId change. Switching tabs does NOT change selection → effect does NOT re-run → no fight.
So actually the onActivate path is SAFE — the effect doesn't re-fire on tab switch. Good. My earlier concern was wrong. The effect only fires on selection change. So switching from inspector to journal tab keeps railTab='journal' (no re-fire).
So no correctness bug there. Good thing I verified the deps.
Stale doc comment in EditorRail.tsx:20 ("bottom sheet") — minor, not a correctness bug.
The actual logic changes (selectMode now closes inspector + deselects on canvas mode tap; onClose for panel tabs drops to a canvas mode) are correct and consistent with the new peek model. The tool strip gating !railTab is correct. The layout reorder is safe on both mobile and desktop.
Let me make sure I'm not missing a real correctness bug by checking the onClose for the inspector path once more — when inspector closes via ✕: select(null); selectPlanting(null); setRailTab(null). The selection effect's else branch (line 223): railTab === 'inspector'? By the time the effect runs, railTab is already null (setRailTab(null) called). But effects run after render with the latest store state. select(null) sets selectedId null → effect re-fires → else branch → getState().railTab === 'inspector'? It's null now → no-op. Fine. No loop.
Everything checks out. No material correctness issues introduced by this PR.
VERDICT: No material issues found
Reviewed through the Correctness lens. I verified the logic changes against the checked-out code rather than trusting the diff.
What I checked and confirmed correct:
selectMode (GardenEditorPage.tsx:239-256): the new else-branch correctly closes the rail for any canvas-mode tap (including inspector, with deselect), and only deselects when railTab === 'inspector'. The exitFocus() on Fixtures is preserved. Behavior matches the PR's stated intent ("tapping a canvas mode closes the panel, deselecting if it was the inspector").
onClose (lines 646-660): inspector close deselects; panel-tab close drops to plants/fixtures based on focusedObjectId. Logic is sound and consistent.
Selection-watching useEffect (216-226): deps are [selectedId, selectedPlantingId, setRailTab, setMode] — zustand setters are stable, so the effect re-fires only on selection-id change, not on railTab change. This means onActivate={setRailTab} (switching from inspector → journal/history tab while a bed is selected) does not get fought back to inspector by the effect. I initially suspected a race here and verified the dependency array rules it out.
Tool-strip gating !railTab (line 668): correctly yields to any open rail peek.
Layout reorder (rail moved from after the mobile bar to before it): on desktop the outer container is md:flex-row and the mobile bar is md:hidden, so the reorder doesn't change desktop visual order; on mobile (flex-col) it correctly produces canvas → rail peek → mode bar. The rail's shrink-0 max-h-[50vh] + canvas flex-1 min-h-0 lets the canvas absorb the space. md:max-h-none/md:w-80 correctly restore the desktop column.
No leftover fixed-overlay/z-index conflicts: BottomNav is suppressed in the editor (showBottomNav = !inEditor, AppShell.tsx:42), and no other code assumed the rail was fixed/z-30.
One non-blocking nit (docs accuracy, not behavior):EditorRail.tsx:20 header comment still says "the same tabs render in a bottom sheet" — now stale since the rail is an in-flow peek, not a bottom sheet. CLAUDE.md flags stale comments as worse than none. Trivial fix: update the comment. Not a correctness issue.
No correctness bugs introduced by this change.
🧹 Code cleanliness & maintainability — Minor issues
I'll verify each finding against the actual code.
All three findings confirmed against the actual code. Outputting the corrected review.
VERDICT: Minor issues
web/src/editor/EditorRail.tsx:20 — the file's top doc comment still says "On a phone the same tabs render in a bottom sheet, which is where the inspector already lived." The body of the file (lines 50–54) was updated to describe the in-flow peek, but this doc paragraph right above was left describing the old bottom-sheet model. The two halves of the file now contradict each other — the "stale comment is worse than none" case CLAUDE.md calls out. Verified by reading the full file.
Suggested fix: update lines 20–21 to match the new in-flow peek description (or drop the obsolete sentence).
web/src/pages/GardenEditorPage.tsx:235-238 — the selectMode comment still says "Journal/Assistant are panel modes, so they open the rail sheet; Fixtures/Plants are canvas modes, so they close a panel rail (but leave an inspector, which is about the selection, alone)." Two staleness issues: (1) "rail sheet" terminology now contradicts the in-flow peek design this PR introduced, and (2) the "leave an inspector alone" claim is now false — the PR's own diff at lines 249-252 makes a canvas mode close the inspector and deselect. Verified by reading the block and the diff hunk.
Suggested fix: "rail sheet" → "rail peek" (or "rail"), and rewrite the "leave an inspector alone" clause to reflect that closing it deselects.
DESIGN.md:134 — "on a phone the same tabs render in the bottom sheet the inspector already used." Same stale wording; the PR updated the sibling paragraph at line 132 to "in-flow peek" but not this one. Verified by reading the file.
Suggested fix: align with the "in-flow peek" wording the PR introduced on the adjacent line.
No duplication, dead code, or structural problems introduced. The moved EditorRail block and the new !railTab gate on the tool strip are clean and the comments around them are accurate. The three findings above are all the same class of issue — stale "sheet" terminology (and one stale behavioral claim) left behind by this PR's terminology/behavior change.
⚡ Performance — No material issues found
Let me verify the canvas fit/re-render behavior when the rail toggles, since that's the one place this layout change could introduce extra work.
I've verified the layout change's performance impact by reading the relevant code paths.
Verification done:
GardenCanvas.tsx:114 — the canvas uses a ResizeObserver on its container; the new in-flow rail means toggling railTab now reflows the canvas container (it didn't when the rail was fixed), firing setSize and re-rendering the SVG.
GardenCanvas.tsx:122-130 — the fit effect is guarded by fitKeyRef.current === key where key = garden.id:focusedObjectId, which does not change on a rail toggle. So the expensive fitToRect animation does not re-run; only a plain re-render of the (memoized) object/plop trees happens.
GardenEditorPage.tsx:668 — !railTab gating unmountsPalette/PlantPlacementTools while the rail is open, which is strictly less rendered work, not more.
GardenEditorPage.tsx:449 — railTabs is rebuilt every render (no useMemo), but only the active tab's render is invoked (EditorRail.tsx:44,89), so inactive tabs cost nothing. This was unchanged by the PR.
The only new cost is one SVG re-render per user-initiated rail open/close (a consequence of going in-flow, which is the whole point of the PR). It's bounded, not in a hot loop, and the costly refit is correctly suppressed. No N+1, no unbounded growth, no per-frame work.
VERDICT: No material issues found
The shift from a fixed overlay to an in-flow flex child means opening/closing the rail now triggers a ResizeObserver callback (GardenCanvas.tsx:114) and one canvas re-render where the old layout did not. This is a single, user-initiated reflow — not a hot path — and the fit animation is correctly skipped by the fitKeyRef guard (GardenCanvas.tsx:124-125, key is garden.id:focusedObjectId, independent of railTab). Confirmed by reading both files. Not material.
🧯 Error handling & edge cases — No material issues found
I've reviewed the diff through the error-handling & edge-cases lens. The changes are UI/state-machine logic with no async error paths, IO, or resource management introduced. Let me verify the key edge cases I'm concerned about: the selectMode closure capturing stale railTab, and the setMode behavior on a non-existent mode.
I've finished reviewing this diff through the error-handling & edge-cases lens, verifying the state-machine transitions and guard behavior against the checked-out code.
Verdict: No material issues found
I specifically checked the following potential edge cases and confirmed each is handled correctly:
selectMode now unconditionally calls setRailTab(null) for canvas modes (previously only closed journal/chat). Verified at GardenEditorPage.tsx:246-255: this is the intended new behavior ("tapping a canvas mode closes the panel"), and for inspector it correctly deselects first. No state is left dangling — the selection effect at :216-226 is idempotent with this (its else-branch only nulls railTab if it's still inspector, which it no longer is).
Closing the rail (onClose) at GardenEditorPage.tsx:646-660 preserves the prior deselect-vs-fallback logic exactly; only its position in the JSX moved. No regression for viewers (canEdit=false) — setMode('fixtures') for a viewer is the same pre-existing behavior, and the tool strip is gated on canEdit, so nothing renders wrongly.
Empty/invalid railTab — EditorRail at EditorRail.tsx:44-45 guards active = tabs.find(...) ?? tabs[0] and if (!active) return null. A railTab id with no matching tab (e.g. chat after a capability flip) falls back rather than crashing; the capability-flip effect at :261-266 subsequently clears it. Unchanged by this PR.
exitFocus interaction with selectMode('fixtures') (:254): exitFocus calls select(null)/selectPlanting(null) after selectMode already did — verified no double-trigger or loop; the selection effect's else-branch no-ops because railTab is already null.
Rail height collapse: EditorRail.tsx:55 uses shrink-0 min-h-0 max-h-[50vh]; shrink-0 prevents collapse and the inner overflow-y-auto (:89) handles overflow. No zero-height edge case.
No new async/error paths, IO, defers, or resource management are introduced by this diff — it's a JSX reorder plus class adjustments. Nothing in my lens to flag.

🔒 Security — No material issues found
No material issues found
This PR is a pure frontend layout refactor: CSS changes (fixed → in-flow flex), component reordering in the JSX tree, and local UI state transitions (mode, railTab). Nothing in the diff touches authn/authz, network requests, user input serialization, DOM injection, secret handling, or any other security-relevant surface. The only behavioral logic change is whether tapping a canvas mode deselects the current object — a UX decision with no security impact.
🎯 Correctness — No material issues found
No material issues found
The PR's core correctness claims check out:
State logic in selectMode — changing from if (railTab === 'journal' || railTab === 'chat') setRailTab(null) to an unconditional setRailTab(null) with a guarded deselect for the inspector is the right fix: a canvas mode should close any open rail, and the inspector's whole purpose is the selection so clearing it is coherent. The old code silently left History open when switching canvas modes, which is now fixed.
onClose handler — the split between "inspector closes → deselect" and "panel closes → drop back to canvas mode" matches the described semantics and doesn't introduce any path that leaves state inconsistent.
Layout/positioning — removing fixed/z-30/inset-x-0 and making the rail an in-flow shrink-0 max-h-[50vh] flex child between the canvas and the mode bar is internally consistent; the canvas container and canvas itself both carry min-h-0 flex-1, so the rail correctly caps at 50vh and the canvas shrinks to fit.
Tool-strip gating — !railTab && (mode === 'fixtures' || mode === 'plants') only affects the mobile bottom strip (the whole block is md:hidden), so desktop is untouched as claimed.
No logic bugs, no stale closures, no undefined symbols, and no semantic/domain errors introduced by the change.

⚡ Performance — No material issues found
No material issues found
This PR is a layout refactor: moving the mobile rail from fixed overlay to an in-flow flex child and making the mode bar always visible. Through the performance lens, there is nothing to flag.
No new allocations in hot paths. The railTabs array with inline render closures is pre-existing and unchanged in structure; it was already recreated on every GardenEditorPage render.
No layout thrashing introduced. Replacing fixed positioning with standard flexbox is if anything cheaper (no composited overlay layer). The min-h-0 and shrink-0 utilities are standard flexbox overflow fixes, not workarounds for expensive reflows.
No unbounded growth or missing pagination. The rail still caps its height at 50vh with overflow-y-auto on the content pane.
No extra re-renders or state churn. The selectMode closure now closes the inspector when entering a canvas mode, but this is user-initiated and not in a loop.
Resize handling is expected behavior. The canvas element now shrinks when the rail opens, which may trigger a ResizeObserver in GardenCanvas. This is the correct and necessary consequence of the non-occluding design, not a regression.
🧯 Error handling & edge cases — No material issues found
No material issues found
I scrutinized the changes through the error-handling & edge-cases lens and found nothing material.
State transitions in selectMode and onClose are guarded. The new inspector-deselect logic only fires when railTab === 'inspector', and the setRailTab(null) / setMode(...) calls are unconditional where intended. Double-calling select(null) from both selectMode and exitFocus is harmless (idempotent no-op).
EditorRail defends against missing tabs.active = tabs.find(...) ?? tabs[0] with if (!active) return null handles an empty array, though railTabs always has ≥3 entries in practice.
No unhandled nulls or empty collections introduced. The rail is conditionally rendered (railTab && ...), and activeId is never passed as null because the guard ensures it.
Effect ordering is safe. Store updates in event handlers (selectMode, onClose) are batched by React; the useEffect keyed on selection IDs reads the already-updated railTab and does not create stale closures.
Boundary/off-by-one: N/A — the PR is UI layout and state routing; no loops, indices, or numeric boundaries were touched.

## Review
I read the full diff plus the surrounding context in `EditorRail.tsx` and `GardenEditorPage.tsx`. This PR is a pure client-side layout change: it converts the mobile rail from `fixed`/overlay positioning to an in-flow flex child, and reorders/reworks when `railTab`/`mode`/`select`/`selectPlanting` state gets reset. There's no new data fetching, no new user input parsing, no `dangerouslySetInnerHTML`, no new API calls, no auth/permission logic, and no touching of secrets or credentials anywhere in the diff. The `EditorRail` component only takes `tabs`/`activeId`/callbacks and renders `tab.label` text and a badge — nothing here reflects untrusted HTML or executes arbitrary content. All permission checks (`canEdit`) are unchanged by this diff and still gate the same UI elements as before.
This diff carries no security-relevant surface — no auth/authz logic, no injection, no untrusted-data handling, no secret handling. Nothing in this lens to report.

## Review — 🎯 Correctness
**VERDICT: No material issues found**
I traced the state machine through `GardenEditorPage.tsx` and `EditorRail.tsx` in detail:
- Verified `EditorMode`/store shape in `web/src/editor/store.ts` — `select(id)` and `selectPlanting(id)` are mutually-exclusive setters (each clears the other field), so the new `selectMode` else-branch calling both `select(null)` and `selectPlanting(null)` when `railTab === 'inspector'` is redundant but not incorrect (consistent with the existing `exitFocus` pattern in the same file).
- Traced the JSX reorder (`EditorRail` moved above the `md:hidden` mode-bar block, `GardenEditorPage.tsx:641-662` vs the removed block at the diff's tail): on desktop the sibling that moved (`shrink-0 md:hidden`) is `display:none`, so its position relative to `EditorRail` doesn't affect visual flex-row order — desktop layout (left col → canvas → rail) is unaffected, matching the PR's "desktop untouched" claim. On mobile the new DOM order (canvas → rail peek → mode bar) matches the intended `flex-col` stacking.
- Checked the `md:shrink-0` class removal in `EditorRail.tsx:56` against the unprefixed `shrink-0` added at `EditorRail.tsx:55` — the unprefixed utility already applies at `md:` and above, so the removal is a no-op, not a behavior change.
- Checked the `!railTab` gate added to the contextual tool strip (`GardenEditorPage.tsx:668`) against the `useEffect` that forces `railTab: 'inspector'` on selection (`GardenEditorPage.tsx:216-226`, unchanged by this diff) — selecting a plop while `mode === 'plants'` correctly swaps the tool strip for the inspector peek rather than showing both.
- Checked `selectMode`'s new deselect-on-mode-switch logic (`GardenEditorPage.tsx:239-256`) against the `railTab==='journal'/'chat'` cases — those branches don't touch selection, matching pre-existing (unchanged-by-diff) behavior, so no new inconsistency is introduced there.
No logic bugs, no incorrect state transitions, and no dubious magic numbers (`50vh` is a UI cap, not a domain constant subject to the CLAUDE.md geometry conventions) were found in this diff.

<details><summary><b>🧹 Code cleanliness & maintainability</b> — Minor issues</summary>
Both findings verified against the actual code.
**Finding 1 confirmed** — `EditorRail.tsx:20-21` reads "On a phone the same tabs render in a bottom sheet, which is where the inspector already lived," directly above the `div` (lines 47-58) whose own inline comment (correctly updated by this diff) describes the new "in-flow PEEK" behavior. `DESIGN.md:134` also still says "on a phone the same tabs render in the bottom sheet the inspector already used," while the adjacent paragraph at `DESIGN.md:132` was correctly rewritten to describe the peek. Both stale mentions verified via grep.
**Finding 2 confirmed** — `GardenEditorPage.tsx` has the same `if (railTab === 'inspector') { select(null); selectPlanting(null) }` logic, each with its own explanatory comment, duplicated between `selectMode` (lines 247-253, new in this diff) and `EditorRail`'s `onClose` handler (lines 647-653, relocated but pre-existing). Genuine duplication of the same invariant in two places.
VERDICT: Minor issues
- `web/src/editor/EditorRail.tsx:20-21` (and `DESIGN.md:134`) — the file-level docstring still describes the mobile rail as "a bottom sheet," the overlay behavior this PR replaces with an in-flow peek. The `EditorRail` div's own inline comment a few lines below (50-54) was correctly updated to describe the peek, but the docstring above it, and a second identical "bottom sheet" mention in `DESIGN.md`'s "One rail, tabs inside it" paragraph, were both missed even though the adjacent "Mobile-first editor" paragraph in `DESIGN.md` was rewritten. Fix: reword both to describe the peek, mirroring the language already used in the div's inline comment.
- `web/src/pages/GardenEditorPage.tsx:247-253` vs `:647-653` — the rule "closing/leaving the inspector rail deselects, because the inspector is about the selection" is implemented twice with near-identical code (`if (railTab === 'inspector') { select(null); selectPlanting(null) }`), once in `selectMode` (new in this diff) and once in `EditorRail`'s `onClose` handler (pre-existing, relocated by this diff). Each copy carries its own comment restating the same invariant — easy to update once and forget the other. Suggest factoring a small `closeInspector()` helper both call sites invoke.

**VERDICT: No material issues found**
This PR is a layout/CSS change (`fixed inset-x-0 bottom-0` → in-flow `flex` peek) plus a JSX reordering and a couple of conditional-branch tweaks (`onClose`/`selectMode` logic, gating the contextual tool strip on `!railTab`). I read both changed files in full (`EditorRail.tsx`, `GardenEditorPage.tsx`) looking for hot-path work, allocations, or query changes.
- No new loops, no new data fetching, no new `.map`/`.filter` over unbounded collections were introduced — `railTabs` (`GardenEditorPage.tsx:449-511`) is the same tab-array construction that existed before the diff, just relocated in the JSX tree at `GardenEditorPage.tsx:641-662` (previously rendered at the bottom, now rendered between the canvas and the mode bar — same conditional mount/unmount on `railTab`, so it costs the same number of renders).
- The CSS change (`max-h-[70vh]` fixed-position sheet → `max-h-[50vh]` flex child) is pure layout; no JS work added.
- The `!railTab` addition to the tool-strip condition (`GardenEditorPage.tsx:668`) only skips rendering `Palette`/`PlantPlacementTools`, which is a reduction in render work when a rail is open, not a regression.
- No new re-render triggers: `railTab` was already a Zustand-selected value used in this component before the diff.
Diff is layout-only from a performance standpoint; nothing to flag in this lens.

This confirms the finding: `ObjectShape` draws a persistent highlighted stroke purely from the boolean `selected` prop, with no separate timeout/animation to clear it. The draft's finding is fully verified against the actual code — I traced the exact reproduction (select an object → tap Journal → tap Fixtures) through `GardenEditorPage.tsx:216-226`, `:239-256`, and `GardenCanvas.tsx:261`/`ObjectShape.tsx:73-74`, and confirmed the gap is real: `railTab === 'inspector'` is checked against a value that can have moved on since selection, leaving `selectedId`/`selectedPlantingId` set with no rail open and no automatic way to clear the canvas highlight (only Escape or tapping empty canvas, as the draft notes).
The rest of the draft's dismissal (CSS reshuffle, `onClose` handler, `tabs.find(...) ?? tabs[0]`) also checks out against the diff — those are structurally unchanged or logically self-contained.
---
**VERDICT: Minor issues**
- `web/src/pages/GardenEditorPage.tsx:249` (`selectMode`, canvas-mode branch) — the deselect-on-close guard only fires `if (railTab === 'inspector')`, a direct check against the *current* rail tab. Selection (`selectedId`/`selectedPlantingId`) and `railTab` can diverge: selecting an object sets `railTab` to `'inspector'` via the effect at `GardenEditorPage.tsx:216-226`, but tapping **Journal** afterwards moves `railTab` to `'journal'` without clearing the selection (the `journal`/`assistant` branches of `selectMode`, lines 241-245, never call `select(null)`/`selectPlanting(null)`). Tapping **Fixtures** (or **Plants**) from that state hits the `else` branch with `railTab === 'journal'`, so the guard at line 249 is skipped, `setRailTab(null)` closes the rail, and `exitFocus()` only runs when `m === 'fixtures' && focusedObjectId != null` — so a plain (non-focused) selection is never cleared either. Net effect: `selectedId` (or `selectedPlantingId`) stays set with no rail open to represent it, and `GardenCanvas` keeps rendering the object/plop as selected (`GardenCanvas.tsx:261`, `ObjectShape.tsx:73-74` draw the highlight straight off the boolean prop, independent of `railTab`) — a stale, persistent highlight recoverable only via Escape or tapping empty canvas space, neither of which is surfaced as an affordance in this mobile flow.
- Verified directly: reproduced the transition sequence through `select`/`selectPlanting` (`store.ts`), the auto-open effect (`GardenEditorPage.tsx:216-226`), `selectMode`'s branches (`GardenEditorPage.tsx:239-256`), `ModeBar` (confirms Fixtures/Journal are always reachable via `onSelect`), and the selection-rendering path in `GardenCanvas.tsx:261` / `ObjectShape.tsx:73-74`, which is unconditioned on `railTab`.
- Suggested fix: in the canvas-mode branch, deselect whenever a selection exists, not only when `railTab === 'inspector'` (e.g. `if (selectedId != null || selectedPlantingId != null) { select(null); selectPlanting(null) }`).

No material issues found
This is a purely presentational/layout change (CSS class swaps and JSX reordering) with no security-relevant surface. I verified:
- `EditorRail.tsx:47-57` — the change only swaps Tailwind classes (`fixed … bottom-0 z-30 … max-h-[70vh]` → `flex max-h-[50vh] min-h-0 shrink-0 …`); no new attributes, no `dangerouslySetInnerHTML`, no href/src wiring.
- `GardenEditorPage.tsx:638-660` — the moved `EditorRail` block and the new `!railTab` gate only call existing state setters (`setRailTab`, `select`, `selectPlanting`, `setMode`, `exitFocus`) already defined in the component; no new taint flow, no untrusted-string rendering, no network/auth changes.
- `selectMode` (`GardenEditorPage.tsx:239-256`) — the new `inspector` branch just calls the same deselect helpers used elsewhere; no authz or input-validation implications.
No injection, authz, SSRF, deserialization, secret-leakage, or unsafe-default concerns are introduced by this diff.

<details><summary><b>🎯 Correctness</b> — No material issues found</summary>
Verdict: No material issues found
I verified the logic through the lens of correctness (semantic/behavioral). The two real behavior changes are intentional and internally consistent:
- **`selectMode` canvas-mode branch** (`GardenEditorPage.tsx:246-255`): Previously it closed only panel rails (`journal`/`chat`) and left an open inspector alone; now it always closes the rail, and when the open tab is `inspector` it also calls `select(null)` + `selectPlanting(null)`. I traced the interactions with the selection-driven inspector effect (`:216-226`) and the focus-follows effect (`:199-206`) — no double-deselect, no stranded state. Since the tool strip is now gated on `!railTab` (`:668`), the inspector had to close for the user to reach the placement tools anyway, so deselecting on the mode switch is the consistent choice. This matches the PR's stated intent ("tapping a canvas mode closes the panel, deselecting if it was the inspector").
- **Layout reordering** (`EditorRail` moved before the mobile bottom bar): On desktop the container is `md:flex-row`; the bottom bar is `md:hidden` (display:none, removed from flex flow), so the rail (`md:static md:w-80`) remains the rightmost column — same effective order as before. On mobile (`flex-col`) the new order is canvas → rail peek → mode bar, which is the intended flex arrangement. The `max-h-[50vh]` cap plus `shrink-0`/`min-h-0` and the canvas `flex-1` behave correctly: the rail grows to content up to 50vh and the canvas flexes to the remainder. No negative-height/overflow correctness bug.
- **`EditorRail` styling** (`EditorRail.tsx:49-57`): Dropping `fixed z-30` and adding `shrink-0 min-h-0 max-h-[50vh]` is consistent with in-flow placement; `md:` overrides restore the desktop column (`md:max-h-none md:w-80`). No regressions for other consumers (the rail is only rendered in `GardenEditorPage`; picker/modals remain separate overlays).
Constants/thresholds checked: `50vh` cap and `100dvh-8rem` outer height are dimensionally consistent (rail is a cap not a min, so canvas never forced negative). No magic-number conversion issues.

<details><summary><b>🧹 Code cleanliness & maintainability</b> — Minor issues</summary>
VERDICT: Minor issues
- **Stale doc comment in `EditorRail.tsx`** — `web/src/editor/EditorRail.tsx:12-21`: the module-level doc block still says the rail is "a fixed 20rem column" (line 18) and that "On a phone the same tabs render in a bottom sheet, which is where the inspector already lived" (lines 20–21). The implementation (inline comment at lines 50–54 and the actual classes at 55–56) now makes it an in-flow ≤50vh peek on mobile with the always-visible mode bar below; the inline comment was updated but the top doc was not, so the file header contradicts the code. Suggested fix: update line 18 to mention the ≤50vh mobile peek / right column split, and drop the "bottom sheet" phrasing.
- **Stale comment in `GardenEditorPage.tsx` `selectMode`** — `web/src/pages/GardenEditorPage.tsx:235-238`: the comment still says canvas modes "leave an inspector, which is about the selection, alone." But the `else` branch now (lines 247–253) closes *every* rail tab and, when the rail was the inspector, deselects via `select(null); selectPlanting(null)` — so the inspector is no longer left alone. The comment directly contradicts the code below it. Suggested fix: rewrite it to match the new "a canvas mode closes whatever's in the rail; the inspector closes with deselect" behavior.
- **Duplicated inspector-close logic** — The `if (railTab === 'inspector') { select(null); selectPlanting(null) }` block now appears in both `selectMode` (`web/src/pages/GardenEditorPage.tsx:249-252`) and the `EditorRail.onClose` handler (`web/src/pages/GardenEditorPage.tsx:650-653`). It's a behavioral invariant ("closing the inspector deselects") expressed twice; if the deselect rule changes one site can drift from the other. Consider a tiny shared `closeInspector()` helper, or have `selectMode` route through the same path. (Confirmed: three `railTab === 'inspector'` hits in the file; the third at line 223 is a different, selection-driven branch.)

<details><summary><b>⚡ Performance</b> — No material issues found</summary>
VERDICT: No material issues found
Through the performance lens, this change is clean:
- The rail moves from a `fixed` overlay to an in-flow flex child. That's a cheaper layout path (no separate stacking-context/overlay compositing), not a regression.
- `EditorRail` was already conditionally mounted via `{railTab && ...}`; the PR only relocates that block, so no new mount/unmount churn or repeated allocation introduced.
- Tab content stays lazily rendered (only `active.render()`), unchanged.
- The one real cost the new layout adds — the canvas (`flex-1`) shrinks when the peek opens, so `GardenCanvas`'s `ResizeObserver` fires once and `setSize` triggers one re-render. I verified the fit effect at `web/src/editor/GardenCanvas.tsx:122-130`: it's guarded by `fitKeyRef.current === key`, so a size-only change (key is `${garden.id}:${focusedObjectId}`, unaffected by rail state) does **not** trigger a re-fit or any extra work. Single resize event, single re-render, no loop (the subsequent render doesn't further change the canvas size).
- No new observers, queries, allocations, or unbounded growth were introduced anywhere in the diff.

(Note: there is a UX consideration — the garden can be clipped when the peek consumes up to 50vh and no re-fit runs — but that is a correctness/UX-lens matter, not a performance one, so I leave it to that reviewer.)

<details><summary><b>🧯 Error handling & edge cases</b> — No material issues found</summary>
**VERDICT: No material issues found**
I reviewed the diff through the error-handling / edge-case lens and verified the relevant code paths in `GardenEditorPage.tsx` and `EditorRail.tsx`:
- **`EditorRail` empty/missing tab** (`EditorRail.tsx:44-45`): `const active = tabs.find(...) ?? tabs[0]; if (!active) return null`. An empty `tabs` array or a stale `activeId` (e.g. `chat` after the assistant capability flips off) falls back to `tabs[0]` and renders nothing if empty — no crash. Verified by reading the file.
- **Assistant capability flip** (`GardenEditorPage.tsx:261-266`): the safety effect already drops `railTab='chat'` when `agent` turns off, so the brief pre-effect render fallback above is corrected, not stranded. Verified.
- **`selectMode` canvas-mode path** (`GardenEditorPage.tsx:246-255`): the new "close inspector → deselect" branch calls `select(null)`/`selectPlanting(null)` before `setRailTab(null)`, which is consistent with the selection-watcher effect at `216-226` (deselecting also clears an inspector `railTab`). No double-set conflict; redundant calls in `exitFocus` are harmless. Verified.
- **`onClose` relocation** (`646-660`): logic is byte-for-byte the same as the removed block; only its position in the tree changed. The `setMode(...)` reads `focusedObjectId` from a fresh per-render closure, so no stale-callback risk. Verified.
- **`!railTab` tool-strip gate** (`668`): hiding the palette/plant strip while a peek is open is a clean conditional; `canEdit`/`mode` guards remain, so view-only and non-canvas modes are unaffected. Verified.
- **Layout bounds** (`EditorRail.tsx:55`): `max-h-[50vh]` + inner `overflow-y-auto` (`89`) means tall rail content scrolls internally rather than blowing out the flex column; `min-h-0` allows the canvas `flex-1` to shrink. No overflow/zero-height edge case introduced. Verified.
No swallowed errors, missing cleanup, panic-on-nil, or unhandled boundary conditions were introduced by this change within my lens.

**No material issues found**
I traced the state transitions in `selectMode`, the `onClose` rail handler, and the selection/focus effects carefully. The new behavior is coherent:
- Switching to a canvas mode unconditionally closes any open rail; if it was the inspector, the selection is cleared too (`GardenEditorPage.tsx:249-253`).
- Closing a non-inspector panel via the rail’s × button drops back to the appropriate canvas mode (`GardenEditorPage.tsx:654-657`).
- The `max-h-[50vh] min-h-0 shrink-0` flex sizing correctly caps the rail and lets the canvas flex to fill the remainder (`EditorRail.tsx:55`).
- The `!railTab` guard on the contextual tool strip properly yields to the peek (`GardenEditorPage.tsx:668`).
- The `EditorRail` DOM move (now before the mode bar) matches its in-flow positioning; no stale `fixed` or `z-30` conflicts remain.
Verified by reading `GardenEditorPage.tsx`, `EditorRail.tsx`, and `store.ts` to confirm type consistency and effect ordering. Nothing incorrect in this lens.

The PR moves `EditorRail` from a fixed-position overlay into the normal flex flow on mobile. From a performance lens, this is a neutral-to-slight-improvement change: the rail was already conditionally rendered, and removing `fixed` positioning eliminates a compositor layer. The `!railTab &&` guard on the contextual tool strip actually *reduces* the rendered subtree when a panel is open. The `railTabs` inline-array-with-render-functions pattern is pre-existing and not introduced here. No N+1 queries, unbounded growth, hot-path allocations, or blocking calls are added.

I'll review this through the Security lens. This is primarily a frontend layout/CSS change, so let me verify there are no security-relevant issues.
This is a pure frontend layout/CSS and component-ordering change — moving `EditorRail` from a `fixed` overlay to an in-flow flex child, and adjusting when the palette/plants strip shows. Through the Security lens:
- No new taint paths: `railTab`, `mode`, and selection state are all internal Zustand-controlled values, not user/external input. None flow into dangerous sinks (no `dangerouslySetInnerHTML`, no `href`/`src` interpolation, no template evaluation).
- No authz regression: the `canEdit` gate on the mobile tool strip (`web/src/pages/GardenEditorPage.tsx:668`) is preserved; the added `!railTab` condition only *further restricts* rendering, it doesn't widen access. EditorRail's tab content and the permission enforcement behind it are untouched by this diff.
- No secret/credential surface: nothing in the touched code handles tokens, keys, or auth state. The assistant-visibility `useEffect` (lines 261–266) reads a capability flag, not a secret.

Let me look at the desktop rail rendering — since `EditorRail` is now rendered outside the inner canvas flex div (at line 641), and the page uses `md:flex-row` at line 527, I need to verify the desktop layout still works.
Now let me verify the desktop layout more carefully. The outer container is `flex h-[calc(100dvh-8rem)] flex-col gap-3 md:flex-row`. So on desktop, children flow in a row. Children are: desktop control column (line 531), the canvas flex div (line 577), the rail (line 641), the mobile bottom div (line 667). On desktop, all four would be in a row? Let me check what's `md:hidden`/`md:block`.
- Line 531: `hidden ... md:block md:w-40` — desktop only ✓
- Line 577: canvas div, `flex-1` ✓
- Line 641: EditorRail — now a direct child (was before too). Has `md:static md:w-80` — visible on desktop as a column ✓
- Line 667: `md:hidden` — mobile only ✓
So desktop = control col + canvas + rail. Same as before (rail was already a sibling). Good — the move is only ordering on mobile (flex-col). Let me verify the prior ordering: the diff shows rail was moved from AFTER the mobile-bottom div (line ~709 area previously) to BEFORE it. On desktop (flex-row), order = control col, canvas, rail, mobile-bar(hidden). Reordering rail before the hidden mobile bar doesn't change visible desktop order. Good.
Now the key correctness concern: on mobile, `EditorRail` is now `shrink-0` with `max-h-[50vh]`, the canvas is `flex-1 min-h-0`, mode bar is `shrink-0`. With `h-[calc(100dvh-8rem)]` and `flex-col`. If rail is 50vh + mode bar + canvas, total could exceed container → canvas flexes down (min-h-0 allows shrink). Good.
But wait — the rail is rendered as a sibling of the inner canvas flex-div (line 577), not inside it. The inner div at 577 is `flex min-h-0 flex-1 flex-col`. So the outer column children: control-col(hidden mobile), inner-canvas-div(flex-1), rail(shrink-0 ≤50vh), mobile-bar(shrink-0). The canvas div is flex-1 so it takes remaining space. Good.
Let me check `selectMode` for the `history` rail case — there's no `history` mode, so the else branch handles closing. Let me check what happens when rail is `history` and user taps a canvas mode.
In `selectMode` else branch (line 246-255): closes rail regardless of which tab, but only deselects if `railTab === 'inspector'`. For history, just closes. Good.
But there's a subtle issue: `selectMode` reads `railTab` from closure. Let me check if `railTab` is from store or local state.
Let me check for any tests that might assert the old behavior, and verify the store.
Let me trace a potential correctness concern with `selectMode` reading `railTab` from the React subscription (line 82) rather than `useEditorStore.getState().railTab`:
In `selectMode` (line 249), `railTab` is the value captured at render time. When user taps a canvas mode while inspector is open: it checks `if (railTab === 'inspector')` then deselects and sets railTab null. That's fine for the current render's value. But there's a subtle ordering issue: `setMode(m)` is called first (line 240), then potentially `select(null)`/`selectPlanting(null)` and `setRailTab(null)`. Multiple separate store updates — each triggers re-render. Not a correctness bug, just batching. Acceptable.
Now let me think about the `useEffect` at line 216-226: when selection changes, it sets railTab to 'inspector'. This still fires on selection. Good — selecting a bed still opens inspector peek.
Let me verify the "history" rail case for closing: `onClose` for history → else branch → `setMode(focusedObjectId != null ? 'plants' : 'fixtures')`. But if you opened history from the **desktop** column button (line 562), on desktop the mode bar is hidden and mode is inert. Calling setMode on desktop is harmless (inert hint). Fine.
Now, one concern: on desktop, the rail used to be `fixed` only on mobile via `fixed inset-x-0 bottom-0` with `md:static`. Now it's `flex ... shrink-0` (no fixed) with `md:static md:w-80`. On desktop, `shrink-0` is fine since it has `md:w-80`. But `max-h-[50vh]` is NOT overridden on desktop? Let me check: `'md:static md:max-h-none md:w-80 ...'`. Yes, `md:max-h-none` overrides. Good.
But `shrink-0` remains on desktop — with `md:w-80` it's a fixed 320px column, shrink-0 prevents shrinking. Good. And `min-h-0` — fine.
Let me check the PublicGardenPage for any rail usage:
Now let me think about a real correctness concern: the inner canvas div at line 577 is `flex min-h-0 flex-1 flex-col`. On mobile, when the rail is open, the rail (shrink-0, ≤50vh) sits as a sibling AFTER this flex-1 div. The outer container is `flex-col`. So the canvas div (flex-1) will shrink to accommodate the rail. Good — garden visible above.
But the inner canvas div contains the mobile top strip (line 580, `md:hidden`), season banner, focus toolbar (desktop only), and the canvas (`flex-1` at 625). When the rail takes up to 50vh, the canvas div shrinks. The canvas inside (line 625 `relative min-h-0 flex-1`) shrinks within it. Fine.
Now, a concern about the **mobile top strip** (line 580) and **EditorHint** overlays (lines 630-635) being inside the canvas flex div which now shrinks. The EditorHint is an overlay — let me check:
Fine — overlays within the canvas div, which is the visible garden area. Acceptable.
Now let me consider a genuine semantic issue: the PR description and DESIGN.md say "≤50vh". But the editor container is `h-[calc(100dvh-8rem)]` (line 527). On mobile the children are: mobile-top-strip (inside canvas div), canvas, rail (≤50vh), mode bar. The rail at 50vh + mode bar (~50px) + top strip could exceed `100dvh-8rem` (8rem ≈ 128px). But since canvas is flex-1 with min-h-0, it absorbs the overflow by shrinking. So no overflow. The "≤50vh" is a cap, not a guarantee of garden visibility size. If the rail content is small, it won't reach 50vh. Fine.
Let me check one more: the `selectMode` for `journal`/`assistant` no longer needs to worry about hiding mode bar (always visible now). But it still sets railTab. When journal mode selected: `setMode('journal')`, `setRailTab('journal')`. Now the mode bar shows Journal highlighted AND the rail shows journal peek. The tool strip is gated on `!railTab` so it hides. Good — matches PR description.
But wait: when in `journal` mode with rail open, and user taps "Plants" mode: `selectMode('plants')` → else branch → `railTab === 'inspector'`? No, it's 'journal'. So just `setRailTab(null)`. Then `m === 'fixtures'`? No, plants. So no exitFocus. Mode becomes plants, rail closes. Tool strip shows (since !railTab and mode==='plants'). Good.
Now what if user is in `journal` mode (rail open) and taps **Journal** again? `selectMode('journal')` → sets mode journal, sets railTab 'journal' (already). No toggle. So tapping the active journal mode doesn't close the rail. Minor UX, not a correctness bug. Previously journal mode didn't show mode bar at all (it was hidden), so this is new behavior but acceptable.
Let me verify the build/test claims by checking for any test files referencing these components:
Let me check the AppShell bottom nav (line 192) — could it conflict with the editor's mode bar / rail now that the rail is in-flow?
Important: `showBottomNav = !!user && !inEditor && !inPublicGarden` (line 42). So in the editor, the BottomNav is NOT shown. Good — no conflict with the editor's mode bar. Let me confirm `inEditor`:
Good. BottomNav hidden in editor. The editor's `h-[calc(100dvh-8rem)]` accounts for the top header (8rem). The mode bar is in-flow at the bottom of that column. No overlap. Correct.
Now let me consider the `selectMode` change closely once more — the old code only closed rail if it was `journal`/`chat`, leaving inspector open. The new code closes rail for ALL canvas modes including inspector (with deselect). This is a behavior change: previously tapping Fixtures while inspector was open did NOT close the inspector. Now it does (and deselects). Is this correct per PR intent? PR says "tapping a canvas mode closes the panel (deselecting if it was the inspector)." Yes, intended. And it makes sense: if you tap Fixtures, you want to arrange, not edit the selection. Correct.
But there's an asymmetry concern: the `useEffect` at line 216 auto-opens inspector when something is selected. So if you tap Fixtures (closes inspector, deselects), then... selection is null, so the effect's else branch won't reopen. Consistent. But what if you tap Fixtures while a bed is focused (not selected)? `focusedObjectId != null` but `selectedId == null`. Tapping Fixtures → else branch → railTab is null (no inspector open since nothing selected) → `setRailTab(null)` (noop) → `exitFocus()`. Good — exits the focused bed. Matches line 254.
Now, one subtle thing: `selectMode('plants')` while inspector is open (a bed selected AND focused). Tapping Plants → else → railTab==='inspector' → deselect + setRailTab(null). But `focusedObjectId` remains. So you're now in Plants mode, focused on the bed, no selection, rail closed. The tool strip shows PlantPlacementTools (since focusedObject exists and is plantable). That seems right — you want to plant in the focused bed.
But wait — previously (old code), tapping Plants while inspector was open: old code `if (railTab === 'journal' || railTab === 'chat') setRailTab(null)` — so inspector stayed open! So old behavior: Plants mode + inspector still open (overlaying). New behavior: Plants mode + inspector closed + deselected. The new behavior is more consistent with the peek model (you can't have the peek open while in a canvas mode that needs the bottom strip... actually the strip is gated on !railTab). This is the intended change. Correct.
Let me double check there are no other callers of `selectMode` or `onClose` that would break:
Now, there's a potential issue with `onActivate={setRailTab}`. When user taps a different tab in the rail (e.g. from inspector to history), `setRailTab('history')` is called. But the `mode` is still whatever it was. If you were in `fixtures` mode with inspector open, then tap "History" tab in the rail → railTab becomes 'history', mode stays 'fixtures'. The tool strip is gated on `!railTab` so it hides. The mode bar still shows Fixtures highlighted. That's fine — you can tap Fixtures to close.
But consider: you're in `plants` mode (focused bed), inspector open for a selected plop. You tap "Journal" tab in the rail. Now railTab='journal', mode='plants'. The selection effect at line 216: `selectedId/selectedPlantingId != null` → it would `setRailTab('inspector')`! Wait — does selecting still keep selection? Tapping a tab doesn't deselect. So `selectedPlantingId` is still set → the effect fires and sets railTab back to 'inspector', overriding 'journal'!
Let me re-read the effect:
Let me check whether anything else relied on the rail being a fixed overlay (e.g., z-index, or the canvas assuming it had the full height):
Let me check GardenCanvas's internal interaction (pan/zoom gestures) to ensure no issue from the rail now being a layout sibling.
The canvas itself is inside a `relative min-h-0 flex-1` div (line 625), which sizes to its parent. The rail is a sibling of the parent (the inner canvas div at 577). So the canvas div flexes to share space with the rail. The canvas's gesture handlers are on the SVG inside, which sizes to the div. No correctness issue with gestures.
I've verified enough. Let me also double-check there are no leftover references to the old "bottom sheet" / overlay behavior in tests or elsewhere that would now be wrong:
The doc comment at `EditorRail.tsx:20` still says "bottom sheet" — now stale (it's an in-flow peek, not a bottom sheet). That's a docs/comment accuracy issue, mild. The CLAUDE.md guidance says stale comments are worse than none. But this is a minor doc nit, not a correctness bug. I'll note it briefly since it's in the changed file's own header.
Now let me verify one final thing — the `selectMode` for the `journal`/`assistant` path: it does NOT close the inspector if one was open. Consider: inspector open (bed selected), then tap Journal mode. `selectMode('journal')` → sets mode 'journal', setRailTab('journal'). The selection effect at 217: selectedId != null → setRailTab('inspector')!! This would yank the rail back to inspector, fighting the journal selection.
Wait — but this was the OLD behavior too. Let me check the old selectMode:
Let me verify the selection-on-click behavior to confirm the "dangling selection" reachability:
Confirmed: tapping an object calls `select(object.id)` (ObjectShape.tsx:58/69), tapping a plop calls `selectPlanting(plop.id)` (PlopMarker.tsx:46), tapping empty canvas calls `select(null)` (GardenCanvas.tsx:180). So a selection is created by tapping a bed in the canvas. With the new `selectMode` closing the inspector on canvas-mode tap, a user CAN now have a dangling selection (tap bed → inspector opens → tap Fixtures → deselect... actually no, it deselects).
Wait, re-reading the new `selectMode` else branch: when tapping a canvas mode with inspector open, it DOES `select(null); selectPlanting(null)`. So no dangling selection in that path. The dangling selection only arises if a future code path closes the inspector without deselecting — but the only such path is `onActivate` to a non-inspector tab, which I analyzed. So the reachability I described (tap bed → tap Journal) is the real dangling path.
Let me confirm tapping a bed while Journal mode is active: tap bed → `select(id)` → selection effect opens inspector + switches mode to fixtures (since mode was 'journal'). So you're NOT left in journal mode. Good — the effect handles it. So to reach the dangling state you'd need: be in fixtures/plants mode (no rail), tap bed (inspector opens, mode stays fixtures), then tap Journal mode button. NOW: selectMode('journal') → setRailTab('journal'), but selection effect re-fires setRailTab('inspector'). Result depends on React batch order. This is genuinely ambiguous/racy but it's pre-existing and not introduced by this PR.
I've thoroughly verified. My lens (Correctness) findings:
1. **Real, in-lens, but pre-existing (not introduced by this PR):** `onActivate={setRailTab}` lets the user switch from the inspector tab to a panel tab (Journal/History/Assistant) while a bed/plop is still selected. The selection-watching `useEffect` (lines 216-226) then unconditionally re-sets `railTab` back to `'inspector'` (line 218), because `selectedId`/`selectedPlantingId` is still non-null. This fights the user's tab choice — tapping Journal/History in the rail while a bed is selected can snap back to the inspector. However, this race exists identically on `main` (the `onActivate`/`setRailTab` wiring and the effect are unchanged by this diff), so it is NOT introduced by this PR. I'll note it as pre-existing, low confidence it manifests given the effect's dependency array only re-fires on selection-id change (not on railTab change) — so in practice the effect does NOT re-run on a pure `setRailTab('journal')` call. Let me re-verify the deps: `[selectedId, selectedPlantingId, setRailTab, setMode]`. `setRailTab`/`setMode` are stable zustand setters. So the effect only re-runs when `selectedId`/`selectedPlantingId` change. Switching tabs does NOT change selection → effect does NOT re-run → no fight.
So actually the `onActivate` path is SAFE — the effect doesn't re-fire on tab switch. Good. My earlier concern was wrong. The effect only fires on selection change. So switching from inspector to journal tab keeps railTab='journal' (no re-fire).
So no correctness bug there. Good thing I verified the deps.
2. **Stale doc comment** in `EditorRail.tsx:20` ("bottom sheet") — minor, not a correctness bug.
3. The actual logic changes (`selectMode` now closes inspector + deselects on canvas mode tap; `onClose` for panel tabs drops to a canvas mode) are correct and consistent with the new peek model. The tool strip gating `!railTab` is correct. The layout reorder is safe on both mobile and desktop.
Let me make sure I'm not missing a real correctness bug by checking the `onClose` for the inspector path once more — when inspector closes via ✕: `select(null); selectPlanting(null); setRailTab(null)`. The selection effect's else branch (line 223): `railTab === 'inspector'`? By the time the effect runs, railTab is already null (setRailTab(null) called). But effects run after render with the latest store state. `select(null)` sets selectedId null → effect re-fires → else branch → `getState().railTab === 'inspector'`? It's null now → no-op. Fine. No loop.
Everything checks out. No material correctness issues introduced by this PR.
## VERDICT: No material issues found
Reviewed through the Correctness lens. I verified the logic changes against the checked-out code rather than trusting the diff.
**What I checked and confirmed correct:**
- `selectMode` (GardenEditorPage.tsx:239-256): the new else-branch correctly closes the rail for *any* canvas-mode tap (including inspector, with deselect), and only deselects when `railTab === 'inspector'`. The `exitFocus()` on Fixtures is preserved. Behavior matches the PR's stated intent ("tapping a canvas mode closes the panel, deselecting if it was the inspector").
- `onClose` (lines 646-660): inspector close deselects; panel-tab close drops to `plants`/`fixtures` based on `focusedObjectId`. Logic is sound and consistent.
- Selection-watching `useEffect` (216-226): deps are `[selectedId, selectedPlantingId, setRailTab, setMode]` — zustand setters are stable, so the effect re-fires **only** on selection-id change, not on `railTab` change. This means `onActivate={setRailTab}` (switching from inspector → journal/history tab while a bed is selected) does *not* get fought back to inspector by the effect. I initially suspected a race here and verified the dependency array rules it out.
- Tool-strip gating `!railTab` (line 668): correctly yields to any open rail peek.
- Layout reorder (rail moved from after the mobile bar to before it): on desktop the outer container is `md:flex-row` and the mobile bar is `md:hidden`, so the reorder doesn't change desktop visual order; on mobile (`flex-col`) it correctly produces canvas → rail peek → mode bar. The rail's `shrink-0 max-h-[50vh]` + canvas `flex-1 min-h-0` lets the canvas absorb the space. `md:max-h-none`/`md:w-80` correctly restore the desktop column.
- No leftover fixed-overlay/z-index conflicts: `BottomNav` is suppressed in the editor (`showBottomNav = !inEditor`, AppShell.tsx:42), and no other code assumed the rail was `fixed`/`z-30`.
**One non-blocking nit (docs accuracy, not behavior):** `EditorRail.tsx:20` header comment still says "the same tabs render in a bottom sheet" — now stale since the rail is an in-flow peek, not a bottom sheet. CLAUDE.md flags stale comments as worse than none. Trivial fix: update the comment. Not a correctness issue.
No correctness bugs introduced by this change.

<details><summary><b>🧹 Code cleanliness & maintainability</b> — Minor issues</summary>
I'll verify each finding against the actual code.
All three findings confirmed against the actual code. Outputting the corrected review.
**VERDICT: Minor issues**
- **`web/src/editor/EditorRail.tsx:20`** — the file's top doc comment still says *"On a phone the same tabs render in a bottom sheet, which is where the inspector already lived."* The body of the file (lines 50–54) was updated to describe the in-flow peek, but this doc paragraph right above was left describing the old bottom-sheet model. The two halves of the file now contradict each other — the "stale comment is worse than none" case CLAUDE.md calls out. Verified by reading the full file.
- Suggested fix: update lines 20–21 to match the new in-flow peek description (or drop the obsolete sentence).
- **`web/src/pages/GardenEditorPage.tsx:235-238`** — the `selectMode` comment still says "Journal/Assistant are panel modes, so they open the rail sheet; Fixtures/Plants are canvas modes, so they close a panel rail (but leave an inspector, which is about the selection, alone)." Two staleness issues: (1) "rail sheet" terminology now contradicts the in-flow peek design this PR introduced, and (2) the "leave an inspector alone" claim is now false — the PR's own diff at lines 249-252 makes a canvas mode close the inspector and deselect. Verified by reading the block and the diff hunk.
- Suggested fix: "rail sheet" → "rail peek" (or "rail"), and rewrite the "leave an inspector alone" clause to reflect that closing it deselects.
- **`DESIGN.md:134`** — "on a phone the same tabs render in the bottom sheet the inspector already used." Same stale wording; the PR updated the sibling paragraph at line 132 to "in-flow peek" but not this one. Verified by reading the file.
- Suggested fix: align with the "in-flow peek" wording the PR introduced on the adjacent line.
No duplication, dead code, or structural problems introduced. The moved `EditorRail` block and the new `!railTab` gate on the tool strip are clean and the comments around them are accurate. The three findings above are all the same class of issue — stale "sheet" terminology (and one stale behavioral claim) left behind by this PR's terminology/behavior change.
</details>
<details><summary><b>⚡ Performance</b> — No material issues found</summary>
Let me verify the canvas fit/re-render behavior when the rail toggles, since that's the one place this layout change could introduce extra work.
I've verified the layout change's performance impact by reading the relevant code paths.
**Verification done:**
- `GardenCanvas.tsx:114` — the canvas uses a `ResizeObserver` on its container; the new in-flow rail means toggling `railTab` now reflows the canvas container (it didn't when the rail was `fixed`), firing `setSize` and re-rendering the SVG.
- `GardenCanvas.tsx:122-130` — the fit effect is guarded by `fitKeyRef.current === key` where `key = garden.id:focusedObjectId`, which does **not** change on a rail toggle. So the expensive `fitToRect` animation does **not** re-run; only a plain re-render of the (memoized) object/plop trees happens.
- `GardenEditorPage.tsx:668` — `!railTab` gating *unmounts* `Palette`/`PlantPlacementTools` while the rail is open, which is strictly less rendered work, not more.
- `GardenEditorPage.tsx:449` — `railTabs` is rebuilt every render (no `useMemo`), but only the active tab's `render` is invoked (`EditorRail.tsx:44,89`), so inactive tabs cost nothing. This was unchanged by the PR.
The only new cost is one SVG re-render per user-initiated rail open/close (a consequence of going in-flow, which is the whole point of the PR). It's bounded, not in a hot loop, and the costly refit is correctly suppressed. No N+1, no unbounded growth, no per-frame work.
## VERDICT: No material issues found
- The shift from a `fixed` overlay to an in-flow flex child means opening/closing the rail now triggers a `ResizeObserver` callback (`GardenCanvas.tsx:114`) and one canvas re-render where the old layout did not. This is a single, user-initiated reflow — not a hot path — and the fit animation is correctly skipped by the `fitKeyRef` guard (`GardenCanvas.tsx:124-125`, key is `garden.id:focusedObjectId`, independent of `railTab`). Confirmed by reading both files. Not material.
</details>
<details><summary><b>🧯 Error handling & edge cases</b> — No material issues found</summary>
I've reviewed the diff through the error-handling & edge-cases lens. The changes are UI/state-machine logic with no async error paths, IO, or resource management introduced. Let me verify the key edge cases I'm concerned about: the `selectMode` closure capturing stale `railTab`, and the `setMode` behavior on a non-existent mode.
I've finished reviewing this diff through the error-handling & edge-cases lens, verifying the state-machine transitions and guard behavior against the checked-out code.
**Verdict: No material issues found**
I specifically checked the following potential edge cases and confirmed each is handled correctly:
- **`selectMode` now unconditionally calls `setRailTab(null)` for canvas modes** (previously only closed `journal`/`chat`). Verified at `GardenEditorPage.tsx:246-255`: this is the intended new behavior ("tapping a canvas mode closes the panel"), and for `inspector` it correctly deselects first. No state is left dangling — the selection effect at `:216-226` is idempotent with this (its else-branch only nulls railTab if it's still `inspector`, which it no longer is).
- **Closing the rail (`onClose`)** at `GardenEditorPage.tsx:646-660` preserves the prior deselect-vs-fallback logic exactly; only its position in the JSX moved. No regression for viewers (`canEdit=false`) — `setMode('fixtures')` for a viewer is the same pre-existing behavior, and the tool strip is gated on `canEdit`, so nothing renders wrongly.
- **Empty/invalid `railTab`** — `EditorRail` at `EditorRail.tsx:44-45` guards `active = tabs.find(...) ?? tabs[0]` and `if (!active) return null`. A railTab id with no matching tab (e.g. `chat` after a capability flip) falls back rather than crashing; the capability-flip effect at `:261-266` subsequently clears it. Unchanged by this PR.
- **`exitFocus` interaction with `selectMode('fixtures')`** (`:254`): `exitFocus` calls `select(null)`/`selectPlanting(null)` after `selectMode` already did — verified no double-trigger or loop; the selection effect's else-branch no-ops because `railTab` is already `null`.
- **Rail height collapse**: `EditorRail.tsx:55` uses `shrink-0 min-h-0 max-h-[50vh]`; `shrink-0` prevents collapse and the inner `overflow-y-auto` (`:89`) handles overflow. No zero-height edge case.
- **No new async/error paths, IO, defers, or resource management** are introduced by this diff — it's a JSX reorder plus class adjustments. Nothing in my lens to flag.

This PR is a pure frontend layout refactor: CSS changes (`fixed` → in-flow flex), component reordering in the JSX tree, and local UI state transitions (`mode`, `railTab`). Nothing in the diff touches authn/authz, network requests, user input serialization, DOM injection, secret handling, or any other security-relevant surface.

</details>
<details><summary><b>🎯 Correctness</b> — No material issues found</summary>
**No material issues found**
The PR's core correctness claims check out:
- **State logic in `selectMode`** — changing from `if (railTab === 'journal' || railTab === 'chat') setRailTab(null)` to an unconditional `setRailTab(null)` with a guarded deselect for the inspector is the right fix: a canvas mode should close any open rail, and the inspector's whole purpose is the selection so clearing it is coherent. The old code silently left History open when switching canvas modes, which is now fixed.
- **`onClose` handler** — the split between "inspector closes → deselect" and "panel closes → drop back to canvas mode" matches the described semantics and doesn't introduce any path that leaves state inconsistent.
- **Layout/positioning** — removing `fixed`/`z-30`/`inset-x-0` and making the rail an in-flow `shrink-0 max-h-[50vh]` flex child between the canvas and the mode bar is internally consistent; the canvas container and canvas itself both carry `min-h-0 flex-1`, so the rail correctly caps at 50vh and the canvas shrinks to fit.
- **Tool-strip gating** — `!railTab && (mode === 'fixtures' || mode === 'plants')` only affects the mobile bottom strip (the whole block is `md:hidden`), so desktop is untouched as claimed.
No logic bugs, no stale closures, no undefined symbols, and no semantic/domain errors introduced by the change.

**No material issues found**
This PR is a layout refactor: moving the mobile rail from `fixed` overlay to an in-flow flex child and making the mode bar always visible. Through the performance lens, there is nothing to flag.
- **No new allocations in hot paths.** The `railTabs` array with inline `render` closures is pre-existing and unchanged in structure; it was already recreated on every `GardenEditorPage` render.
- **No layout thrashing introduced.** Replacing `fixed` positioning with standard flexbox is if anything cheaper (no composited overlay layer). The `min-h-0` and `shrink-0` utilities are standard flexbox overflow fixes, not workarounds for expensive reflows.
- **No unbounded growth or missing pagination.** The rail still caps its height at `50vh` with `overflow-y-auto` on the content pane.
- **No extra re-renders or state churn.** The `selectMode` closure now closes the inspector when entering a canvas mode, but this is user-initiated and not in a loop.
- **Resize handling is expected behavior.** The canvas element now shrinks when the rail opens, which may trigger a ResizeObserver in `GardenCanvas`. This is the correct and necessary consequence of the non-occluding design, not a regression.
</details>
<details><summary><b>🧯 Error handling & edge cases</b> — No material issues found</summary>
**No material issues found**
I scrutinized the changes through the error-handling & edge-cases lens and found nothing material.
- **State transitions in `selectMode` and `onClose` are guarded.** The new inspector-deselect logic only fires when `railTab === 'inspector'`, and the `setRailTab(null)` / `setMode(...)` calls are unconditional where intended. Double-calling `select(null)` from both `selectMode` and `exitFocus` is harmless (idempotent no-op).
- **`EditorRail` defends against missing tabs.** `active = tabs.find(...) ?? tabs[0]` with `if (!active) return null` handles an empty array, though `railTabs` always has ≥3 entries in practice.
- **No unhandled nulls or empty collections introduced.** The rail is conditionally rendered (`railTab && ...`), and `activeId` is never passed as `null` because the guard ensures it.
- **Effect ordering is safe.** Store updates in event handlers (`selectMode`, `onClose`) are batched by React; the `useEffect` keyed on selection IDs reads the already-updated `railTab` and does not create stale closures.
- **Boundary/off-by-one: N/A** — the PR is UI layout and state routing; no loops, indices, or numeric boundaries were touched.

<sub>Automated adversarial review by Gadfly — consensus across the model swarm. Advisory only — does not block merge.</sub>
Gadfly on #101:
- EditorRail's module doc still described a "fixed 20rem column / bottom
sheet"; updated to the in-flow peek (desktop column, phone ≤50vh peek
between canvas and mode bar).
- (correctness) A canvas-mode tap only deselected when railTab was
'inspector', so a selection made, then routed through Journal/Assistant,
survived a return to Fixtures/Plants — the canvas kept highlighting it
with no inspector. Canvas modes now clear the selection unconditionally.
- Dedup: the "closing the inspector deselects" pair lived in both selectMode
and the rail's onClose; extracted a clearSelection() helper (also used by
exitFocus) and fixed the now-stale "leave an inspector alone" comment.

Closes #101. Part of #96. Implements both of your end-of-run calls: always-visible mode bar + non-occluding inspector.
Before
On a phone, selecting a bed opened the rail as a bottom sheet that covered the whole garden, and opening Journal/Assistant hid the mode bar until you closed it. You couldn't see what you were editing, or switch modes without backing out.
After — the rail is an in-flow peek
Instead of
fixed bottom-0 max-h-70vhoverlaying everything,EditorRailon mobile is a ≤50vh flex child the editor places between the canvas and the mode bar:So the garden stays visible in the top band, the mode bar stays reachable below, and you can tap another mode straight from an open panel. The contextual tool strip yields to the peek (gated on
!railTab), and tapping a canvas mode closes the panel (deselecting if it was the inspector). No fixed-positioning or full-bleed refactor needed — the flex column does it.Desktop is untouched — the same
EditorRailis the right-hand column there (md:styles); the mode bar staysmd:hidden.Verified live

Review
I read the full diff plus the surrounding context in
EditorRail.tsxandGardenEditorPage.tsx. This PR is a pure client-side layout change: it converts the mobile rail fromfixed/overlay positioning to an in-flow flex child, and reorders/reworks whenrailTab/mode/select/selectPlantingstate gets reset. There's no new data fetching, no new user input parsing, nodangerouslySetInnerHTML, no new API calls, no auth/permission logic, and no touching of secrets or credentials anywhere in the diff. TheEditorRailcomponent only takestabs/activeId/callbacks and renderstab.labeltext and a badge — nothing here reflects untrusted HTML or executes arbitrary content. All permission checks (canEdit) are unchanged by this diff and still gate the same UI elements as before.This diff carries no security-relevant surface — no auth/authz logic, no injection, no untrusted-data handling, no secret handling. Nothing in this lens to report.

GardenEditorPage.tsxandEditorRail.tsxin detail:EditorMode/store shape inweb/src/editor/store.ts—select(id)andselectPlanting(id)are mutually-exclusive setters (each clears the other field), so the newselectModeelse-branch calling bothselect(null)andselectPlanting(null)whenrailTab === 'inspector'is redundant but not incorrect (consistent with the existingexitFocuspattern in the same file).EditorRailmoved above themd:hiddenmode-bar block,GardenEditorPage.tsx:641-662vs the removed block at the diff's tail): on desktop the sibling that moved (shrink-0 md:hidden) isdisplay:none, so its position relative toEditorRaildoesn't affect visual flex-row order — desktop layout (left col → canvas → rail) is unaffected, matching the PR's "desktop untouched" claim. On mobile the new DOM order (canvas → rail peek → mode bar) matches the intendedflex-colstacking.md:shrink-0class removal inEditorRail.tsx:56against the unprefixedshrink-0added atEditorRail.tsx:55— the unprefixed utility already applies atmd:and above, so the removal is a no-op, not a behavior change.!railTabgate added to the contextual tool strip (GardenEditorPage.tsx:668) against theuseEffectthat forcesrailTab: 'inspector'on selection (GardenEditorPage.tsx:216-226, unchanged by this diff) — selecting a plop whilemode === 'plants'correctly swaps the tool strip for the inspector peek rather than showing both.selectMode's new deselect-on-mode-switch logic (GardenEditorPage.tsx:239-256) against therailTab==='journal'/'chat'cases — those branches don't touch selection, matching pre-existing (unchanged-by-diff) behavior, so no new inconsistency is introduced there.No logic bugs, no incorrect state transitions, and no dubious magic numbers (

Both findings verified against the actual code.
Finding 1 confirmed —
EditorRail.tsx:20-21reads "On a phone the same tabs render in a bottom sheet, which is where the inspector already lived," directly above thediv(lines 47-58) whose own inline comment (correctly updated by this diff) describes the new "in-flow PEEK" behavior.DESIGN.md:134also still says "on a phone the same tabs render in the bottom sheet the inspector already used," while the adjacent paragraph atDESIGN.md:132was correctly rewritten to describe the peek. Both stale mentions verified via grep.Finding 2 confirmed —
GardenEditorPage.tsxhas the sameif (railTab === 'inspector') { select(null); selectPlanting(null) }logic, each with its own explanatory comment, duplicated betweenselectMode(lines 247-253, new in this diff) andEditorRail'sonClosehandler (lines 647-653, relocated but pre-existing). Genuine duplication of the same invariant in two places.VERDICT: Minor issues
web/src/editor/EditorRail.tsx:20-21(andDESIGN.md:134) — the file-level docstring still describes the mobile rail as "a bottom sheet," the overlay behavior this PR replaces with an in-flow peek. TheEditorRaildiv's own inline comment a few lines below (50-54) was correctly updated to describe the peek, but the docstring above it, and a second identical "bottom sheet" mention inDESIGN.md's "One rail, tabs inside it" paragraph, were both missed even though the adjacent "Mobile-first editor" paragraph inDESIGN.mdwas rewritten. Fix: reword both to describe the peek, mirroring the language already used in the div's inline comment.web/src/pages/GardenEditorPage.tsx:247-253vs:647-653— the rule "closing/leaving the inspector rail deselects, because the inspector is about the selection" is implemented twice with near-identical code (if (railTab === 'inspector') { select(null); selectPlanting(null) }), once inselectMode(new in this diff) and once inEditorRail'sonClosehandler (pre-existing, relocated by this diff). Each copy carries its own comment restating the same invariant — easy to update once and forget the other. Suggest factoring a smallcloseInspector()helper both call sites invoke.⚡ Performance — No material issues found
VERDICT: No material issues found
This PR is a layout/CSS change (
fixed inset-x-0 bottom-0→ in-flowflexpeek) plus a JSX reordering and a couple of conditional-branch tweaks (onClose/selectModelogic, gating the contextual tool strip on!railTab). I read both changed files in full (EditorRail.tsx,GardenEditorPage.tsx) looking for hot-path work, allocations, or query changes..map/.filterover unbounded collections were introduced —railTabs(GardenEditorPage.tsx:449-511) is the same tab-array construction that existed before the diff, just relocated in the JSX tree atGardenEditorPage.tsx:641-662(previously rendered at the bottom, now rendered between the canvas and the mode bar — same conditional mount/unmount onrailTab, so it costs the same number of renders).max-h-[70vh]fixed-position sheet →max-h-[50vh]flex child) is pure layout; no JS work added.!railTabaddition to the tool-strip condition (GardenEditorPage.tsx:668) only skips renderingPalette/PlantPlacementTools, which is a reduction in render work when a rail is open, not a regression.railTabwas already a Zustand-selected value used in this component before the diff.Diff is layout-only from a performance standpoint; nothing to flag in this lens.
🧯 Error handling & edge cases — Minor issues
This confirms the finding:
ObjectShapedraws a persistent highlighted stroke purely from the booleanselectedprop, with no separate timeout/animation to clear it. The draft's finding is fully verified against the actual code — I traced the exact reproduction (select an object → tap Journal → tap Fixtures) throughGardenEditorPage.tsx:216-226,:239-256, andGardenCanvas.tsx:261/ObjectShape.tsx:73-74, and confirmed the gap is real:railTab === 'inspector'is checked against a value that can have moved on since selection, leavingselectedId/selectedPlantingIdset with no rail open and no automatic way to clear the canvas highlight (only Escape or tapping empty canvas, as the draft notes).The rest of the draft's dismissal (CSS reshuffle,
onClosehandler,tabs.find(...) ?? tabs[0]) also checks out against the diff — those are structurally unchanged or logically self-contained.VERDICT: Minor issues
web/src/pages/GardenEditorPage.tsx:249(selectMode, canvas-mode branch) — the deselect-on-close guard only firesif (railTab === 'inspector'), a direct check against the current rail tab. Selection (selectedId/selectedPlantingId) andrailTabcan diverge: selecting an object setsrailTabto'inspector'via the effect atGardenEditorPage.tsx:216-226, but tapping Journal afterwards movesrailTabto'journal'without clearing the selection (thejournal/assistantbranches ofselectMode, lines 241-245, never callselect(null)/selectPlanting(null)). Tapping Fixtures (or Plants) from that state hits theelsebranch withrailTab === 'journal', so the guard at line 249 is skipped,setRailTab(null)closes the rail, andexitFocus()only runs whenm === 'fixtures' && focusedObjectId != null— so a plain (non-focused) selection is never cleared either. Net effect:selectedId(orselectedPlantingId) stays set with no rail open to represent it, andGardenCanvaskeeps rendering the object/plop as selected (GardenCanvas.tsx:261,ObjectShape.tsx:73-74draw the highlight straight off the boolean prop, independent ofrailTab) — a stale, persistent highlight recoverable only via Escape or tapping empty canvas space, neither of which is surfaced as an affordance in this mobile flow.select/selectPlanting(store.ts), the auto-open effect (GardenEditorPage.tsx:216-226),selectMode's branches (GardenEditorPage.tsx:239-256),ModeBar(confirms Fixtures/Journal are always reachable viaonSelect), and the selection-rendering path inGardenCanvas.tsx:261/ObjectShape.tsx:73-74, which is unconditioned onrailTab.railTab === 'inspector'(e.g.if (selectedId != null || selectedPlantingId != null) { select(null); selectPlanting(null) }).glm-5.2:cloud (ollama-cloud) — Minor issues

This is a purely presentational/layout change (CSS class swaps and JSX reordering) with no security-relevant surface. I verified:
EditorRail.tsx:47-57— the change only swaps Tailwind classes (fixed … bottom-0 z-30 … max-h-[70vh]→flex max-h-[50vh] min-h-0 shrink-0 …); no new attributes, nodangerouslySetInnerHTML, no href/src wiring.GardenEditorPage.tsx:638-660— the movedEditorRailblock and the new!railTabgate only call existing state setters (setRailTab,select,selectPlanting,setMode,exitFocus) already defined in the component; no new taint flow, no untrusted-string rendering, no network/auth changes.selectMode(GardenEditorPage.tsx:239-256) — the newinspectorbranch just calls the same deselect helpers used elsewhere; no authz or input-validation implications.No injection, authz, SSRF, deserialization, secret-leakage, or unsafe-default concerns are introduced by this diff.
🎯 Correctness — No material issues found
Verdict: No material issues found
I verified the logic through the lens of correctness (semantic/behavioral). The two real behavior changes are intentional and internally consistent:
selectModecanvas-mode branch (GardenEditorPage.tsx:246-255): Previously it closed only panel rails (journal/chat) and left an open inspector alone; now it always closes the rail, and when the open tab isinspectorit also callsselect(null)+selectPlanting(null). I traced the interactions with the selection-driven inspector effect (:216-226) and the focus-follows effect (:199-206) — no double-deselect, no stranded state. Since the tool strip is now gated on!railTab(:668), the inspector had to close for the user to reach the placement tools anyway, so deselecting on the mode switch is the consistent choice. This matches the PR's stated intent ("tapping a canvas mode closes the panel, deselecting if it was the inspector").Layout reordering (
EditorRailmoved before the mobile bottom bar): On desktop the container ismd:flex-row; the bottom bar ismd:hidden(display:none, removed from flex flow), so the rail (md:static md:w-80) remains the rightmost column — same effective order as before. On mobile (flex-col) the new order is canvas → rail peek → mode bar, which is the intended flex arrangement. Themax-h-[50vh]cap plusshrink-0/min-h-0and the canvasflex-1behave correctly: the rail grows to content up to 50vh and the canvas flexes to the remainder. No negative-height/overflow correctness bug.EditorRailstyling (EditorRail.tsx:49-57): Droppingfixed z-30and addingshrink-0 min-h-0 max-h-[50vh]is consistent with in-flow placement;md:overrides restore the desktop column (md:max-h-none md:w-80). No regressions for other consumers (the rail is only rendered inGardenEditorPage; picker/modals remain separate overlays).Constants/thresholds checked:
50vhcap and100dvh-8remouter height are dimensionally consistent (rail is a cap not a min, so canvas never forced negative). No magic-number conversion issues.🧹 Code cleanliness & maintainability — Minor issues
VERDICT: Minor issues
Stale doc comment in
EditorRail.tsx—web/src/editor/EditorRail.tsx:12-21: the module-level doc block still says the rail is "a fixed 20rem column" (line 18) and that "On a phone the same tabs render in a bottom sheet, which is where the inspector already lived" (lines 20–21). The implementation (inline comment at lines 50–54 and the actual classes at 55–56) now makes it an in-flow ≤50vh peek on mobile with the always-visible mode bar below; the inline comment was updated but the top doc was not, so the file header contradicts the code. Suggested fix: update line 18 to mention the ≤50vh mobile peek / right column split, and drop the "bottom sheet" phrasing.Stale comment in
GardenEditorPage.tsxselectMode—web/src/pages/GardenEditorPage.tsx:235-238: the comment still says canvas modes "leave an inspector, which is about the selection, alone." But theelsebranch now (lines 247–253) closes every rail tab and, when the rail was the inspector, deselects viaselect(null); selectPlanting(null)— so the inspector is no longer left alone. The comment directly contradicts the code below it. Suggested fix: rewrite it to match the new "a canvas mode closes whatever's in the rail; the inspector closes with deselect" behavior.Duplicated inspector-close logic — The
if (railTab === 'inspector') { select(null); selectPlanting(null) }block now appears in bothselectMode(web/src/pages/GardenEditorPage.tsx:249-252) and theEditorRail.onClosehandler (web/src/pages/GardenEditorPage.tsx:650-653). It's a behavioral invariant ("closing the inspector deselects") expressed twice; if the deselect rule changes one site can drift from the other. Consider a tiny sharedcloseInspector()helper, or haveselectModeroute through the same path. (Confirmed: threerailTab === 'inspector'hits in the file; the third at line 223 is a different, selection-driven branch.)⚡ Performance — No material issues found

I verified the fit effect atweb/src/editor/GardenCanvas.tsx:122-130: it's guarded byfitKeyRef.current === key, so a size-only change (key is${garden.id}:${focusedObjectId}, unaffected by rail state) does not trigger a re-fit or any extra work. Single resize event, single re-render, no loop (the subsequent render doesn't further change the canvas size).gadfly-findings(Note: there is a UX consideration — the garden can be clipped when the peek consumes up to 50vh and no re-fit runs — but that is a correctness/UX-lens matter, not a performance one, so I leave it to that reviewer.)

Let me look at the desktop rail rendering — since
EditorRailis now rendered outside the inner canvas flex div (at line 641), and the page usesmd:flex-rowat line 527, I need to verify the desktop layout still works.Now let me verify the desktop layout more carefully. The outer container is
flex h-[calc(100dvh-8rem)] flex-col gap-3 md:flex-row. So on desktop, children flow in a row. Children are: desktop control column (line 531), the canvas flex div (line 577), the rail (line 641), the mobile bottom div (line 667). On desktop, all four would be in a row? Let me check what'smd:hidden/md:block.hidden ... md:block md:w-40— desktop only ✓flex-1✓md:static md:w-80— visible on desktop as a column ✓md:hidden— mobile only ✓So desktop = control col + canvas + rail. Same as before (rail was already a sibling). Good — the move is only ordering on mobile (flex-col). Let me verify the prior ordering: the diff shows rail was moved from AFTER the mobile-bottom div (line ~709 area previously) to BEFORE it. On desktop (flex-row), order = control col, canvas, rail, mobile-bar(hidden). Reordering rail before the hidden mobile bar doesn't change visible desktop order. Good.
Now the key correctness concern: on mobile,
EditorRailis nowshrink-0withmax-h-[50vh], the canvas isflex-1 min-h-0, mode bar isshrink-0. Withh-[calc(100dvh-8rem)]andflex-col. If rail is 50vh + mode bar + canvas, total could exceed container → canvas flexes down (min-h-0 allows shrink). Good.But wait — the rail is rendered as a sibling of the inner canvas flex-div (line 577), not inside it. The inner div at 577 is
flex min-h-0 flex-1 flex-col. So the outer column children: control-col(hidden mobile), inner-canvas-div(flex-1), rail(shrink-0 ≤50vh), mobile-bar(shrink-0). The canvas div is flex-1 so it takes remaining space. Good.Let me check
selectModefor thehistoryrail case — there's nohistorymode, so the else branch handles closing. Let me check what happens when rail ishistoryand user taps a canvas mode.In
selectModeelse branch (line 246-255): closes rail regardless of which tab, but only deselects ifrailTab === 'inspector'. For history, just closes. Good.But there's a subtle issue:
selectModereadsrailTabfrom closure. Let me check ifrailTabis from store or local state.Let me check for any tests that might assert the old behavior, and verify the store.
Let me trace a potential correctness concern with
selectModereadingrailTabfrom the React subscription (line 82) rather thanuseEditorStore.getState().railTab:In
selectMode(line 249),railTabis the value captured at render time. When user taps a canvas mode while inspector is open: it checksif (railTab === 'inspector')then deselects and sets railTab null. That's fine for the current render's value. But there's a subtle ordering issue:setMode(m)is called first (line 240), then potentiallyselect(null)/selectPlanting(null)andsetRailTab(null). Multiple separate store updates — each triggers re-render. Not a correctness bug, just batching. Acceptable.Now let me think about the
useEffectat line 216-226: when selection changes, it sets railTab to 'inspector'. This still fires on selection. Good — selecting a bed still opens inspector peek.Let me verify the "history" rail case for closing:
onClosefor history → else branch →setMode(focusedObjectId != null ? 'plants' : 'fixtures'). But if you opened history from the desktop column button (line 562), on desktop the mode bar is hidden and mode is inert. Calling setMode on desktop is harmless (inert hint). Fine.Now, one concern: on desktop, the rail used to be
fixedonly on mobile viafixed inset-x-0 bottom-0withmd:static. Now it'sflex ... shrink-0(no fixed) withmd:static md:w-80. On desktop,shrink-0is fine since it hasmd:w-80. Butmax-h-[50vh]is NOT overridden on desktop? Let me check:'md:static md:max-h-none md:w-80 ...'. Yes,md:max-h-noneoverrides. Good.But
shrink-0remains on desktop — withmd:w-80it's a fixed 320px column, shrink-0 prevents shrinking. Good. Andmin-h-0— fine.Let me check the PublicGardenPage for any rail usage:
Now let me think about a real correctness concern: the inner canvas div at line 577 is
flex min-h-0 flex-1 flex-col. On mobile, when the rail is open, the rail (shrink-0, ≤50vh) sits as a sibling AFTER this flex-1 div. The outer container isflex-col. So the canvas div (flex-1) will shrink to accommodate the rail. Good — garden visible above.But the inner canvas div contains the mobile top strip (line 580,
md:hidden), season banner, focus toolbar (desktop only), and the canvas (flex-1at 625). When the rail takes up to 50vh, the canvas div shrinks. The canvas inside (line 625relative min-h-0 flex-1) shrinks within it. Fine.Now, a concern about the mobile top strip (line 580) and EditorHint overlays (lines 630-635) being inside the canvas flex div which now shrinks. The EditorHint is an overlay — let me check:
Fine — overlays within the canvas div, which is the visible garden area. Acceptable.
Now let me consider a genuine semantic issue: the PR description and DESIGN.md say "≤50vh". But the editor container is
h-[calc(100dvh-8rem)](line 527). On mobile the children are: mobile-top-strip (inside canvas div), canvas, rail (≤50vh), mode bar. The rail at 50vh + mode bar (~50px) + top strip could exceed100dvh-8rem(8rem ≈ 128px). But since canvas is flex-1 with min-h-0, it absorbs the overflow by shrinking. So no overflow. The "≤50vh" is a cap, not a guarantee of garden visibility size. If the rail content is small, it won't reach 50vh. Fine.Let me check one more: the
selectModeforjournal/assistantno longer needs to worry about hiding mode bar (always visible now). But it still sets railTab. When journal mode selected:setMode('journal'),setRailTab('journal'). Now the mode bar shows Journal highlighted AND the rail shows journal peek. The tool strip is gated on!railTabso it hides. Good — matches PR description.But wait: when in
journalmode with rail open, and user taps "Plants" mode:selectMode('plants')→ else branch →railTab === 'inspector'? No, it's 'journal'. So justsetRailTab(null). Thenm === 'fixtures'? No, plants. So no exitFocus. Mode becomes plants, rail closes. Tool strip shows (since !railTab and mode==='plants'). Good.Now what if user is in
journalmode (rail open) and taps Journal again?selectMode('journal')→ sets mode journal, sets railTab 'journal' (already). No toggle. So tapping the active journal mode doesn't close the rail. Minor UX, not a correctness bug. Previously journal mode didn't show mode bar at all (it was hidden), so this is new behavior but acceptable.Let me verify the build/test claims by checking for any test files referencing these components:
Let me check the AppShell bottom nav (line 192) — could it conflict with the editor's mode bar / rail now that the rail is in-flow?
Important:
showBottomNav = !!user && !inEditor && !inPublicGarden(line 42). So in the editor, the BottomNav is NOT shown. Good — no conflict with the editor's mode bar. Let me confirminEditor:Good. BottomNav hidden in editor. The editor's
h-[calc(100dvh-8rem)]accounts for the top header (8rem). The mode bar is in-flow at the bottom of that column. No overlap. Correct.Now let me consider the
selectModechange closely once more — the old code only closed rail if it wasjournal/chat, leaving inspector open. The new code closes rail for ALL canvas modes including inspector (with deselect). This is a behavior change: previously tapping Fixtures while inspector was open did NOT close the inspector. Now it does (and deselects). Is this correct per PR intent? PR says "tapping a canvas mode closes the panel (deselecting if it was the inspector)." Yes, intended. And it makes sense: if you tap Fixtures, you want to arrange, not edit the selection. Correct.But there's an asymmetry concern: the
useEffectat line 216 auto-opens inspector when something is selected. So if you tap Fixtures (closes inspector, deselects), then... selection is null, so the effect's else branch won't reopen. Consistent. But what if you tap Fixtures while a bed is focused (not selected)?focusedObjectId != nullbutselectedId == null. Tapping Fixtures → else branch → railTab is null (no inspector open since nothing selected) →setRailTab(null)(noop) →exitFocus(). Good — exits the focused bed. Matches line 254.Now, one subtle thing:
selectMode('plants')while inspector is open (a bed selected AND focused). Tapping Plants → else → railTab==='inspector' → deselect + setRailTab(null). ButfocusedObjectIdremains. So you're now in Plants mode, focused on the bed, no selection, rail closed. The tool strip shows PlantPlacementTools (since focusedObject exists and is plantable). That seems right — you want to plant in the focused bed.But wait — previously (old code), tapping Plants while inspector was open: old code
if (railTab === 'journal' || railTab === 'chat') setRailTab(null)— so inspector stayed open! So old behavior: Plants mode + inspector still open (overlaying). New behavior: Plants mode + inspector closed + deselected. The new behavior is more consistent with the peek model (you can't have the peek open while in a canvas mode that needs the bottom strip... actually the strip is gated on !railTab). This is the intended change. Correct.Let me double check there are no other callers of
selectModeoronClosethat would break:Now, there's a potential issue with
onActivate={setRailTab}. When user taps a different tab in the rail (e.g. from inspector to history),setRailTab('history')is called. But themodeis still whatever it was. If you were infixturesmode with inspector open, then tap "History" tab in the rail → railTab becomes 'history', mode stays 'fixtures'. The tool strip is gated on!railTabso it hides. The mode bar still shows Fixtures highlighted. That's fine — you can tap Fixtures to close.But consider: you're in
plantsmode (focused bed), inspector open for a selected plop. You tap "Journal" tab in the rail. Now railTab='journal', mode='plants'. The selection effect at line 216:selectedId/selectedPlantingId != null→ it wouldsetRailTab('inspector')! Wait — does selecting still keep selection? Tapping a tab doesn't deselect. SoselectedPlantingIdis still set → the effect fires and sets railTab back to 'inspector', overriding 'journal'!Let me re-read the effect:
Let me check whether anything else relied on the rail being a fixed overlay (e.g., z-index, or the canvas assuming it had the full height):
Let me check GardenCanvas's internal interaction (pan/zoom gestures) to ensure no issue from the rail now being a layout sibling.
The canvas itself is inside a
relative min-h-0 flex-1div (line 625), which sizes to its parent. The rail is a sibling of the parent (the inner canvas div at 577). So the canvas div flexes to share space with the rail. The canvas's gesture handlers are on the SVG inside, which sizes to the div. No correctness issue with gestures.I've verified enough. Let me also double-check there are no leftover references to the old "bottom sheet" / overlay behavior in tests or elsewhere that would now be wrong:
The doc comment at
EditorRail.tsx:20still says "bottom sheet" — now stale (it's an in-flow peek, not a bottom sheet). That's a docs/comment accuracy issue, mild. The CLAUDE.md guidance says stale comments are worse than none. But this is a minor doc nit, not a correctness bug. I'll note it briefly since it's in the changed file's own header.Now let me verify one final thing — the
selectModefor thejournal/assistantpath: it does NOT close the inspector if one was open. Consider: inspector open (bed selected), then tap Journal mode.selectMode('journal')→ sets mode 'journal', setRailTab('journal'). The selection effect at 217: selectedId != null → setRailTab('inspector')!! This would yank the rail back to inspector, fighting the journal selection.Wait — but this was the OLD behavior too. Let me check the old selectMode:
Let me verify the selection-on-click behavior to confirm the "dangling selection" reachability:
Confirmed: tapping an object calls
select(object.id)(ObjectShape.tsx:58/69), tapping a plop callsselectPlanting(plop.id)(PlopMarker.tsx:46), tapping empty canvas callsselect(null)(GardenCanvas.tsx:180). So a selection is created by tapping a bed in the canvas. With the newselectModeclosing the inspector on canvas-mode tap, a user CAN now have a dangling selection (tap bed → inspector opens → tap Fixtures → deselect... actually no, it deselects).Wait, re-reading the new
selectModeelse branch: when tapping a canvas mode with inspector open, it DOESselect(null); selectPlanting(null). So no dangling selection in that path. The dangling selection only arises if a future code path closes the inspector without deselecting — but the only such path isonActivateto a non-inspector tab, which I analyzed. So the reachability I described (tap bed → tap Journal) is the real dangling path.Let me confirm tapping a bed while Journal mode is active: tap bed →
select(id)→ selection effect opens inspector + switches mode to fixtures (since mode was 'journal'). So you're NOT left in journal mode. Good — the effect handles it. So to reach the dangling state you'd need: be in fixtures/plants mode (no rail), tap bed (inspector opens, mode stays fixtures), then tap Journal mode button. NOW: selectMode('journal') → setRailTab('journal'), but selection effect re-fires setRailTab('inspector'). Result depends on React batch order. This is genuinely ambiguous/racy but it's pre-existing and not introduced by this PR.I've thoroughly verified. My lens (Correctness) findings:
onActivate={setRailTab}lets the user switch from the inspector tab to a panel tab (Journal/History/Assistant) while a bed/plop is still selected. The selection-watchinguseEffect(lines 216-226) then unconditionally re-setsrailTabback to'inspector'(line 218), becauseselectedId/selectedPlantingIdis still non-null. This fights the user's tab choice — tapping Journal/History in the rail while a bed is selected can snap back to the inspector. However, this race exists identically onmain(theonActivate/setRailTabwiring and the effect are unchanged by this diff), so it is NOT introduced by this PR. I'll note it as pre-existing, low confidence it manifests given the effect's dependency array only re-fires on selection-id change (not on railTab change) — so in practice the effect does NOT re-run on a puresetRailTab('journal')call. Let me re-verify the deps:[selectedId, selectedPlantingId, setRailTab, setMode].setRailTab/setModeare stable zustand setters. So the effect only re-runs whenselectedId/selectedPlantingIdchange. Switching tabs does NOT change selection → effect does NOT re-run → no fight.So actually the
onActivatepath is SAFE — the effect doesn't re-fire on tab switch. Good. My earlier concern was wrong. The effect only fires on selection change. So switching from inspector to journal tab keeps railTab='journal' (no re-fire).So no correctness bug there. Good thing I verified the deps.
Stale doc comment in
EditorRail.tsx:20("bottom sheet") — minor, not a correctness bug.The actual logic changes (
selectModenow closes inspector + deselects on canvas mode tap;onClosefor panel tabs drops to a canvas mode) are correct and consistent with the new peek model. The tool strip gating!railTabis correct. The layout reorder is safe on both mobile and desktop.Let me make sure I'm not missing a real correctness bug by checking the
onClosefor the inspector path once more — when inspector closes via ✕:select(null); selectPlanting(null); setRailTab(null). The selection effect's else branch (line 223):railTab === 'inspector'? By the time the effect runs, railTab is already null (setRailTab(null) called). But effects run after render with the latest store state.select(null)sets selectedId null → effect re-fires → else branch →getState().railTab === 'inspector'? It's null now → no-op. Fine. No loop.Everything checks out. No material correctness issues introduced by this PR.
VERDICT: No material issues found
Reviewed through the Correctness lens. I verified the logic changes against the checked-out code rather than trusting the diff.
What I checked and confirmed correct:
selectMode(GardenEditorPage.tsx:239-256): the new else-branch correctly closes the rail for any canvas-mode tap (including inspector, with deselect), and only deselects whenrailTab === 'inspector'. TheexitFocus()on Fixtures is preserved. Behavior matches the PR's stated intent ("tapping a canvas mode closes the panel, deselecting if it was the inspector").onClose(lines 646-660): inspector close deselects; panel-tab close drops toplants/fixturesbased onfocusedObjectId. Logic is sound and consistent.useEffect(216-226): deps are[selectedId, selectedPlantingId, setRailTab, setMode]— zustand setters are stable, so the effect re-fires only on selection-id change, not onrailTabchange. This meansonActivate={setRailTab}(switching from inspector → journal/history tab while a bed is selected) does not get fought back to inspector by the effect. I initially suspected a race here and verified the dependency array rules it out.!railTab(line 668): correctly yields to any open rail peek.md:flex-rowand the mobile bar ismd:hidden, so the reorder doesn't change desktop visual order; on mobile (flex-col) it correctly produces canvas → rail peek → mode bar.

EditorRail.tsx:20header comment still says "the same tabs render in a bottom sheet" — now stale since the rail is an in-flow peek, not a bottom sheet. CLAUDE.md flags stale comments as worse than none. Trivial fix: update the comment. Not a correctness issue.No correctness bugs introduced by this change.
🧹 Code cleanliness & maintainability — Minor issues

All three findings confirmed against the actual code. Outputting the corrected review.
VERDICT: Minor issues
web/src/editor/EditorRail.tsx:20— the file's top doc comment still says "On a phone the same tabs render in a bottom sheet, which is where the inspector already lived." The body of the file (lines 50–54) was updated to describe the in-flow peek, but this doc paragraph right above was left describing the old bottom-sheet model. The two halves of the file now contradict each other — the "stale comment is worse than none" case CLAUDE.md calls out. Verified by reading the full file.web/src/pages/GardenEditorPage.tsx:235-238— theselectModecomment still says "Journal/Assistant are panel modes, so they open the rail sheet; Fixtures/Plants are canvas modes, so they close a panel rail (but leave an inspector, which is about the selection, alone)." Two staleness issues: (1) "rail sheet" terminology now contradicts the in-flow peek design this PR introduced, and (2) the "leave an inspector alone" claim is now false — the PR's own diff at lines 249-252 makes a canvas mode close the inspector and deselect. Verified by reading the block and the diff hunk.DESIGN.md:134— "on a phone the same tabs render in the bottom sheet the inspector already used." Same stale wording; the PR updated the sibling paragraph at line 132 to "in-flow peek" but not this one. Verified by reading the file.No duplication, dead code, or structural problems introduced. The moved
EditorRailblock and the new!railTabgate on the tool strip are clean and the comments around them are accurate. The three findings above are all the same class of issue — stale "sheet" terminology (and one stale behavioral claim) left behind by this PR's terminology/behavior change.⚡ Performance — No material issues found
Let me verify the canvas fit/re-render behavior when the rail toggles, since that's the one place this layout change could introduce extra work.
I've verified the layout change's performance impact by reading the relevant code paths.
Verification done:
GardenCanvas.tsx:114— the canvas uses aResizeObserveron its container; the new in-flow rail means togglingrailTabnow reflows the canvas container (it didn't when the rail wasfixed), firingsetSizeand re-rendering the SVG.GardenCanvas.tsx:122-130— the fit effect is guarded byfitKeyRef.current === keywherekey = garden.id:focusedObjectId, which does not change on a rail toggle. So the expensivefitToRectanimation does not re-run; only a plain re-render of the (memoized) object/plop trees happens.GardenEditorPage.tsx:668—!railTabgating unmountsPalette/PlantPlacementToolswhile the rail is open, which is strictly less rendered work, not more.GardenEditorPage.tsx:449—railTabsis rebuilt every render (nouseMemo), but only the active tab'srenderis invoked (EditorRail.tsx:44,89), so inactive tabs cost nothing. This was unchanged by the PR.The only new cost is one SVG re-render per user-initiated rail open/close (a consequence of going in-flow, which is the whole point of the PR). It's bounded, not in a hot loop, and the costly refit is correctly suppressed. No N+1, no unbounded growth, no per-frame work.
VERDICT: No material issues found
fixedoverlay to an in-flow flex child means opening/closing the rail now triggers aResizeObservercallback (GardenCanvas.tsx:114) and one canvas re-render where the old layout did not. This is a single, user-initiated reflow — not a hot path — and the fit animation is correctly skipped by thefitKeyRefguard (GardenCanvas.tsx:124-125, key isgarden.id:focusedObjectId, independent ofrailTab). Confirmed by reading both files. Not material.🧯 Error handling & edge cases — No material issues found
I've reviewed the diff through the error-handling & edge-cases lens. The changes are UI/state-machine logic with no async error paths, IO, or resource management introduced. Let me verify the key edge cases I'm concerned about: the
selectModeclosure capturing stalerailTab, and thesetModebehavior on a non-existent mode.I've finished reviewing this diff through the error-handling & edge-cases lens, verifying the state-machine transitions and guard behavior against the checked-out code.
Verdict: No material issues found
I specifically checked the following potential edge cases and confirmed each is handled correctly:
selectModenow unconditionally callssetRailTab(null)for canvas modes (previously only closedjournal/chat). Verified atGardenEditorPage.tsx:246-255: this is the intended new behavior ("tapping a canvas mode closes the panel"), and forinspectorit correctly deselects first. No state is left dangling — the selection effect at:216-226is idempotent with this (its else-branch only nulls railTab if it's stillinspector, which it no longer is).Closing the rail (
onClose) atGardenEditorPage.tsx:646-660preserves the prior deselect-vs-fallback logic exactly; only its position in the JSX moved. No regression for viewers (canEdit=false) —setMode('fixtures')for a viewer is the same pre-existing behavior, and the tool strip is gated oncanEdit, so nothing renders wrongly.Empty/invalid

This PR is a pure frontend layout refactor: CSS changes (

Nothing in the diff touches authn/authz, network requests, user input serialization, DOM injection, secret handling, or any other security-relevant surface. The only behavioral logic change is whether tapping a canvas mode deselects the current object — a UX decision with no security impact.🎯 Correctness — No material issues found

The PR's core correctness claims check out:
selectMode— changing fromif (railTab === 'journal' || railTab === 'chat') setRailTab(null)to an unconditionalsetRailTab(null)with a guarded deselect for the inspector is the right fix: a canvas mode should close any open rail, and the inspector's whole purpose is the selection so clearing it is coherent. The old code silently left History open when switching canvas modes, which is now fixed.onClosehandler — the split between "inspector closes → deselect" and "panel closes → drop back to canvas mode" matches the described semantics and doesn't introduce any path that leaves state inconsistent.fixed/z-30/inset-x-0and making the rail an in-flowshrink-0 max-h-[50vh]flex child between the canvas and the mode bar is internally consistent; the canvas container and canvas itself both carrymin-h-0 flex-1, so the rail correctly caps at 50vh and the canvas shrinks to fit.!railTab && (mode === 'fixtures' || mode === 'plants')only affects the mobile bottom strip (the whole block ismd:hidden), so desktop is untouched as claimed.No logic bugs, no stale closures, no undefined symbols, and no semantic/domain errors introduced by the change.
