docs: fix stale VAPID env names (NAVI_VAPID_* -> NAVI_PUSH_VAPID_*, per config.py)

webclient: settings page split into GnTabs sections (Account/Notifications/Synapse/MCP)

webclient: settings loaders switched to kit circle spinner (GnLoader circle)

mcp keys: tool-management tools aligned with BYOK (test_mcp_tool runs on user key, mcp_status marks key slots)

docs: mcp.md (per-user MCP keys BYOK), /mcp-keys endpoints, user_key config

webclient: MCP user keys panel (BYOK) + frontend tests

mcp keys W2: per-user client clones, KeyResolver wiring, user_id in call path

mcp keys W1: user_key config slot, encrypted keystore, /mcp-keys REST

webclient: top margin on settings header

docs: synapse integration guide, special sessions filter, new endpoints ...

- docs/synapse.md: full guide — gateway, reaction runner pipeline,
  notify tool, per-user settings, service sessions in the UI
- index/tools/config/api: entry point + built-in tools + env vars +
  GET /sessions special param + synapse REST/webhook endpoints

webclient: Synapse reactions settings + service sessions toggle ...

- sidebar: service-sessions toggle (special=true fetch replaces the
  regular list, active search drops out), muted style + robot icon on
  special items in the list
- settings: Synapse reactions panel — enable switch, completion push
  preference (always / only failures / never), notification destination
  (app / app+Synapse / Synapse, Synapse options disabled while no
  source key), reaction instructions editor with save + edit history
  (author and reason per version)
- stores: synapseReactions store; sessions store fetches respect
  showSpecial; getSessions passes special param
- vitest for api/session store/panel; dist rebuilt

synapse settings: source_ready flag in GET/PUT response ...

Tells the UI whether Synapse-linked options are usable (source key
configured); not persisted, computed per request.

synapse reactions W3: reaction runner, notify tool, gateway hookup ...

- navi/synapse/reactions.py: fire-and-forget reaction run — per-user
  reactions_enabled gate, one-shot dispatcher meta-pass (visible profiles
  only, hidden dispatcher, secretary fallback), special=True session
  headed by the resolved profile, headless agent run via the orchestrator
  run registry, finalise: app push per completion_notify +
  low-level reaction.finished/failed event to Synapse
- navi/synapse/outbound.py: source-side emit (syn_* key from env,
  silent when not configured)
- navi/tools/notify.py: notify tool — message + level (info/warning/
  intervention), both legs per push_target, honest delivered/skipped result
- push/service.py: notify_custom without cooldown
- gateway: verified + non-duplicate delivery schedules the reaction
- profiles: notify added to native tools (7 profiles)

synapse reactions W2: hidden dispatcher profile + synapse_instructions tool

synapse reactions W1: special sessions flag + per-user reaction settings and instruction history

webclient: remove session list dividers, 42px sidebar logo, truncate long file names in preview pill

handbook alignment: profile.updated mirror, health contract, Synapse gateway ...

Handbook gaps closed (10-platform auth/health/notifications):

- webhooks: handle user.profile_updated — mirror the gnexus-auth profile
  into navi_users (name, contact fields, avatar_url — new column, boot
  migration); role/permissions keep their dedicated events
- auth: avatar_url now flows through the login upsert and the API-token
  resolution path
- /health: status is now the aggregate of the sub-checks (degraded embed
  or hive no longer reports plain ok); embed probe cached for 10 s; body
  grew the machine-readable checks{} map, legacy embed/hive payloads kept
- Synapse: s2s delivery gateway — POST /webhooks/synapse (both spellings),
  per-user delivery secrets (synapse_targets, Fernet-encrypted, shown
  once), verification via gnexus-synapse v0.1.2 client lib, idempotent
  event ids; deliveries are verified and logged for now — navi generates
  no outbound events by decision; web-push stays as the local browser
  channel
- webclient settings: Synapse deliveries panel (add/revoke targets)

webclient: revert LoginScreen to the custom card ...

The kit login-card markup read heavier (uppercase header, wide chrome
border) than the original centered card — restoring the previous
version per user preference.

webclient: LoginScreen rebuilt on kit markup ...

The SSO-only login doesn't fit GnLoginCard's username/password form (the
adapter always renders both fields), so the escape-hatch card is replaced
with the kit's own login-card markup (article.card.login-card + header +
card-content + GnButton) — the same contract kit.css ships for
GnLoginCard, minus the form. Custom card border/title/subtitle styles are
gone; overlay keeps positioning only.

webclient: apply kit radii to content-cards and viewed-image thumbs, fix dead scss tokens ...

The content-card and ArtifactsPanel style blocks used @use 'kit-deps'
inside <style scoped> without lang=scss, so sass never ran: the
-radius-md token stayed a literal in the built CSS and the
browser saw border-radius: -radius-md (invalid → 0 corners).
Both blocks now declare lang=scss and compile to the kit's 6px radius.

Also rounds the corners of user-message image attachments and adds the
missing label prop on the tools-collapse icon button (kit dev warning).

webclient: cap thinking body at 800px, smooth details close, Navi-viewed images grouped in artifacts ...

- thinking-body: max-height 800px + inner scroll so long reasoning
  doesn't grow the whole chat
- content-card: body stays mounted after first open (no v-show teardown
  at toggle time) — ::details-content now has real content to shrink,
  so collapsing animates smoothly instead of snapping to 0 in a frame
- synthetic '[Image loaded via ...]' messages from vision tools are no
  longer rendered as user bubbles; their images are collected (live from
  tool_call metadata, and from history) into a viewed-images group at
  the top of the artifacts tab, thumbnails open the lightbox

webclient: tool-count badge, kit-styled content card, thinking corner gap, chat top gap, drop duplicate reconnect notice

webclient + navi: session title click-to-rename; empty rename regenerates via LLM

navi: session naming folds agent's final replies into context

navi: delete-timing log in session delete route

webclient: profile chips — wheel + swipe scroll, no status markers, clicked chip slides into view

webclient: profile chips in sidebar; New Chat opens welcome; profile tap starts session; welcome grid 4-up

webclient: lightbox closes on browser/back-gesture ...

Opening the lightbox pushes a history entry ({lightbox: true}); popstate
closes the modal instead of walking the session history (mobile back
gesture used to leave the modal open and jump sessions). Cross/backdrop
close pops the pushed entry, so the gesture history has no stale records

navi: session delete covers pending (not-yet-persisted) sessions ...

Lazy persistence keeps never-messaged sessions out of the DB, so the bare
DELETE FROM sessions reported 0 rows for a very real session and the API
answered 404 'Session not found' — the webclient's list cleanup and the
welcome-screen redirect silently never ran.

webclient: artifacts panel — link hover color, single-row tabs, refresh moved right ...

- .link-item hover/active title: text-light instead of black (unreadsble
  on the row hover tint)
- tab chips never wrap: container queries on the panel squeeze padding/
  font/gap and drop the icons below 360px
- files refresh: default-size GnIconButton aligned to the toolbar right
