Audits and fixes ground-teleport/flat-fall/toss-momentum physics bugs,
fixes drag getting stuck via missing pointercancel handling, replaces
sprite-based speech bubbles with real HTML text/emoji bubbles, adds
drag-onto-icon "investigate" reactions and idle chatter, merges the
name badge and reaction bubble into one floating element, and caps the
bubble to one line with a teleprompter-style auto-scroll instead of
ellipsizing overflow text.

Implements plans/2026-07-20-desktop-mascot.md. New code under
web/src/lib/mascot/ (types/sprites/render/state/behavior/actions/
stimuli + Mascot/MascotLayer/RadialMenu/NameDialog components) plus
CC0 sprite sheets at web/public/mascot/ (chicken + Onocentaur egg pack
+ reaction bubbles). MascotLayer is inserted into Desktop.svelte after
WindowLayer; <2-line integration.
Tamagotchi: egg -> chick -> adult lifecycle persisted to
localStorage['oikos-mascot'] (debounced 300ms). Egg hatches on first
naming (no timed incubation per implementation deviation). Chick/adult
wander, peck, sleep, blink autonomously via a weighted-random FSM; the
chicken walks above windows (ground line = highest window top edge
beneath its x, recomputed each tick from wmState; rides the ground when
the window beneath is dragged).
Interaction: draggable with flutter-fall physics on release mid-air;
plain click = pet (heart bubble + happy anim); right-click opens a
rounded-button radial menu (Interact/Care/Identity/Debug nested groups)
mirroring the desktop's own right-click menu styling; auto-flips above/
left near screen edges.
Awareness: stimulus bus subscribes to chat.ts streaming, activity.ts
activityLog (knowledge-entry diff), events.ts liveEvents (critical/
signal -> alarmed, execution -> happy), with priority+cooldown gating.
Egg-stage reactions are suppressed. Reaction bubbles are anti-aliased.
Sprite loop runs at ~60fps via setTimeout (not rAF) per GraphBackground
convention, dt clamped to 100ms; position via transform: translate3d
+ will-change: transform for compositor-friendly motion. Z-index
ordering: WindowLayer z-40 < MascotLayer z-[45] < desktop context menu
z-50 < RadialMenu/NameDialog z-[60].
Docs: plan + docs/mascot/README.md (MBSE subsystem model) updated to
Implemented with a deviations note covering hatch-on-naming, PNG-sheet
art, button-column radial menu, 60fps loop, egg-reaction suppression,
and window-walking ground model. VERSION bumped 0.7.13 -> 0.8.0.
Three UI issues reported after the neutral-gray redesign:
- favicon.svg was still filled #58a6ff (the pre-redesign accent blue);
changed to white to match the sidebar logo mark.
- Sidebar nav items all showed a filled background even when inactive.
Root cause: sidebar-menu-button.svelte (and -sub-button) rendered
`data-active="false"` as a literal attribute, but Tailwind's bare
`data-active:` variant matches attribute *presence*, not value — so
data-active:bg-sidebar-accent applied to every item regardless of
state. Fixed by emitting the attribute only when active
(`isActive || undefined`), a latent bug in the vendored shadcn
component that read as intentional until flagged.
- Tailwind's preflight resets <button> to cursor: default, so no button
in the app showed a pointer. Added one base rule restoring
cursor: pointer for buttons, [role=button], links, summary, and
select (respecting :disabled / aria-disabled) rather than annotating
each call site — covers new interactive elements automatically.
Risk: reversible_low (UI-only).
Verification: verified in the browser preview that inactive sidebar
items are transparent (only the current page shows a background),
nav buttons report cursor: pointer via computed styles, and the
favicon renders white in the tab.

Problem: the web UI felt dead and hard to navigate — the Entities table
had no health/freshness signal (just a meaningless row-mutation
timestamp), no way to see what was actually monitoring an entity,
sessions couldn't be reopened, and every drill-down was a full page
navigation that lost the list.
Change:
- Entities table: Updated column replaced with a health dot + relative
"checked Xm ago", sourced from the backend's new health/last_check_at
fields.
- New EntityDetailContent.svelte extracted from EntityDetail.svelte and
shared between the full #/entity/:slug page and a new EntitySheet.svelte
opened from the Entities table (master-detail, row click opens a panel
instead of navigating away). Adds a Monitoring card listing the
entity's check_defs (kind, interval, enabled/disabled with
click-to-toggle via the existing PatchCheck endpoint) and renders
attributes as key/value pairs instead of raw JSON.
- Sessions: fixed a bug where clicking a session loaded it into the
chat store but never navigated to the chat page, so nothing appeared
to happen. Added a SessionRail inside Chat so switching sessions
never leaves the chat surface.
- Fixed the local dev proxy (vite.config.ts): production Caddy strips
the /agent prefix before forwarding to nomos; the dev proxy didn't,
so every session/chat fetch 404'd locally while working in prod.
- Found and fixed a real latent bug while testing the session fix:
chat.ts's loadSessionMessages passed the persisted tool_calls array
straight through, but nomos stores the tool_use and tool_result as
two entries sharing one id. Chat.svelte's keyed {#each tool (tool.id)}
throws on the duplicate key, which silently blanked the entire
message list — invisible until sessions were actually clickable.
Fixed by merging tool_calls by id before rendering, matching the
shape the live-streaming path already produces.
- UI polish: sidebar logo is now just the omicron mark in white (was
icon+text in the accent color); removed the sheet overlay's
backdrop-blur (distracting per feedback); the Attributes/Relations/
Signals grids used viewport-based lg:/3xl: breakpoints, which forced
multi-column layouts based on browser width regardless of the sheet's
actual rendered width — switched to Tailwind v4 container queries
(@lg:/@2xl:/@3xl:) so layout responds to the real available width in
both the full page and the narrower sheet.
Risk: reversible_low (UI-only; no destructive operations; the tool_calls
merge and dev-proxy fix are corrections to broken paths, not behavior
changes to working ones).
Verification: npx tsc --noEmit clean (excluding pre-existing unrelated
.svelte type-resolution warnings). Manually verified in the browser
preview against the live dev API: Entities table health column renders
correctly; clicking a row opens the EntitySheet with a populated
Monitoring card (16 checks for host:hubris, verified via psql that
check_defs.target_id links them correctly); clicking a session now
loads its full transcript inline (was blank before the tool_calls fix);
sheet has no blur and lays out single/multi-column correctly at the
sheet's actual width.
