webclient: keep MCP rows at content height on a phone ...

.mcp-keys-row stacks into a column below 768px, and .mcp-keys-info kept
its flex: 1 1 240px. That basis is a width in the desktop row and a
height once the row stacks, so every server reserved 240px and its text
sat at the top of the gap — 402px for a row whose content is 90px.

Back to content height on mobile only, and drop the kit's .form-group
bottom margin there: the row's own flex gap already separates the field
from the buttons.

admin: POST /admin/tools/reload ...

reload_tools is granted to one profile only (tool_developer), so an admin
whose profile lacks it cannot reload at all — the tool answers "not
found" instead of reloading. The route calls the same reload_all() the
tool does, behind require_admin, for whoever is logged in as an admin.

An admin may read: ok, the tools loaded, the registry total, per-file
errors, names in enabled.json nothing answers to, and the MCP/providers
summary.

reload: pick up the new code, and drop MCP tools that are gone ...

reload_tools reported success while three separate things kept it from
doing what it says.

The bytecode cache is keyed on (mtime in whole seconds, file size), so a
tool edited to the same length inside the same second as its previous
load re-ran the OLD code — the reload was real, the new version was not
live. The loader now compiles the source itself instead of consulting
__pycache__ (importlib.invalidate_caches() does not help here).

MCP registrations only ever grew: register_mcp_tools called
register_external, and unregister_external was used in one place, so a
server removed from the config or a tool a server stopped exposing
stayed in the registry and failed only when the model called it. Reload
now clears external tools and rebuilds them.

enabled.json naming a tool that failed to load (the gmail/html2text case)
was visible only as a log line. It is now part of the report.

The reload itself moves to navi/core/reload.py, one implementation shared
by the tool and the admin route, so the two cannot leave different
toolsets behind. list_tools.py also read enabled.json through its own
cwd-relative path, which made it disagree with the real toolset, and the
class-based loader rejected execute(self, params, ctx=None) — the shape
every built-in uses.

config: point the tgclient MCP server at the live host ...

The committed value was the local dev address (localhost:8710, where
~/Projects/tgclient-mcp serves it) and the server ran with the wrong public
host, so the tools never connected. Both clones now use
https://tgclientmcp.gnexus.space/mcp.

No default headers: the key is per-user by design (BYOD settings field), and
until one is entered the server answers 401.

switch_profile: run the switch alone, then the batch on the new tools ...

A tool called in the same batch as switch_profile was still dispatched against
the old tool_map and died with "tool 'X' not found" — reload_tools did, twice
in one session. The batch is now split: the switch runs first, its
ProfileSwitched event is watched for the target profile, the tools are
re-resolved from it, and the remaining calls run against the new set.

The turn's own profile binding is deliberately left alone — the
end-of-iteration reload in run_stream() is what rebinds profile/llm/schemas,
and pre-setting session.profile_id here would make it skip that step.

switch_profile: deliver profile_switched, report the new toolset ...

The tool took its sink as `ctx.event_sink if ctx else current_event_sink.get()`,
but the agent loop builds tool_ctx with event_sink=None — the ContextVar is the
real channel — so the branch always picked None, the event was silently
dropped, and the profile badge in the header never moved. plan.py already had
the fall-through (`if ctx and ctx.event_sink else current_event_sink.get()`);
this is the same fix.

The result also said nothing about what the switch changed, so the model kept
calling tools the target profile does not have (reload_tools after leaving
tool_developer). It now names the gained and lost tools, and the timing claim
is corrected: the new prompt and tools are in force from the next step of the
same turn, not "from the next message".

Allocate message sequence numbers in the DB, not in memory ...

save() numbered new messages from Session.db_next_sequence, a counter read
when the session was loaded. Any second writer of the same session handed
out the numbers it still believed were free, and the two inserts collided on
UNIQUE(session_id, sequence_number) — in production, when switch_profile
loaded the session mid-run and saved it back. The turn died with
"Internal error: duplicate key value violates unique constraint".

The range is now claimed inside save()'s transaction with a single
UPDATE ... RETURNING, so concurrent writers serialize on the session row,
and GREATEST() seeds the pre-counter sessions whose next_sequence is still 0
instead of relying on a racy max()+1 fallback in memory.

switch_profile itself no longer saves a session at all: it repoints the row
through a narrow set_profile() UPDATE, which keeps it out of the running
turn's way. It runs mid-turn on a session the turn still holds, so saving a
second copy from there was the collision in the first place.

config: add the gntodo MCP server

config: capture the live server configuration ...

Profiles gain the gntodo / gnexus-book / gnexus-creds scopes for agent and
subagent runs, refreshed model lists, and write access where the live setup
has it. MCP server configs pick up their user_key slots, gnexus-book learns
delete_pending_change, and the hard-panel / synapse / tgclient servers join
the tree.

Merge remote-tracking branch 'origin/master'

Await the session pool in notify and three neighbours ...

PgSessionStore._get_pool() is async, and four call sites passed its coroutine
straight into a store constructor, so the first query inside died with
"'coroutine' object has no attribute 'fetchrow'": notify always failed, the
reaction runner never got past reading its settings, synapse_instructions was
unusable, and the BYOK resolver caught the AttributeError and silently fell
back to the default credential.

The tests missed it because each one mocked the store or the pool provider
away; the new ones run on a fake asyncpg pool with nothing faked below the tool.

Merge origin/master (b7743f8): PWA icons, MCP settings tab, android push, runbook

webclient: serve the PWA artwork past the images cache ...

/images/* is served cache-first from IMAGES_CACHE, which activate deliberately
keeps across builds. That is right for content whose URL is unique and wrong
for the app's own artwork: /images/icon-*, /images/logo-icon* and
/images/apple-splash/* keep their URLs while their contents change with the
logo, so a browser that had once loaded an icon would keep showing the old one
even after a deploy — and the apple-touch-icon is linked from index.html, so it
does travel through the page and the service worker.

Those paths now go network-first with a cached fallback (offline still works);
every other /images/ request is untouched.

Tests: frontend 148 passed; backend 1367 passed, 1 skipped.

webclient: draw the PWA icons at full size again ...

The maskable icons and the apple-touch-icon carried the mark at 21% of the
canvas — the artwork scaled down and pasted in the centre — so on a home
screen the logo read as a fragment of itself. The mark takes 73.4% of the
canvas in logo.svg and in the launcher tile of the Android app icon; that is
the proportion all five files use now.

scripts/gen_pwa_icons.py redraws the mark from logo.svg's geometry with
Pillow (already a project dependency, no SVG rasterizer needed) and writes the
whole set, so the scale lives in one constant; --check measures what is on
disk and reports SUSPECT if it drifts again. Two runs produce identical bytes.

The regenerated icon-192/512 are geometrically identical to the rsvg-rendered
ones they replace: ink bbox 376x376 with 68px insets at 50% coverage, and the
same ink mass across the stroke. Only the antialiasing bytes differ.

dist/ rebuilt (it carries a copy of public/ and is served by the backend).

Tests: frontend 148 passed; backend 1367 passed, 1 skipped.

deploy: runbook for updating a running instance ...

Adds deploy/UPDATE.md: preflight, the branch shapes (master vs the
tracked .env on deploy), what to rebuild before pushing (the frontend
dist is committed and the server never builds it), the verification
commands that prove the new bundle is the one being served, rollback,
and the traps — tracked secrets in mcp_servers.d/, gitignored vendor
kit dist, service-worker cache, Android app needing only a restart.

Linked from deploy/README.md.

MCP settings tab: list every connected server, slot only where declared ...

The tab was empty on every install: it listed only servers whose config
declares a `user_key` slot, and no config declared one — which read as
"no MCP servers connected" even though five are wired to profiles.

- GET /mcp-keys now returns every server referenced by at least one
  profile, keyed ones first, with `accepts_user_key`, the slot location
  (null when there is none) and the profile ids that connect it. The
  per-user key store is skipped entirely when nothing has a slot.
- gnexus-creds declares `user_key: {header: Authorization, prefix:
  "Bearer "}` — it is the one server carrying a shared credential, so its
  personal-key field is now real: users with a key run under their own,
  users without one fall back to the shared default.
- The panel lists all servers (transport + profiles), dims the keyless
  rows, and shows a key input only for slotted ones, spelling out the
  shared-key fallback.

docs/api.md and docs/mcp.md updated; backend 1367 passed, webclient 148.

Android app: native push notifications via JS bridge + background hold ...

WebView has no Push API, so the app shows notifications natively:

- NaviBridge JS interface (window.NaviAndroid): notify(), permission
  request with a 'navi-perm-result' event callback, background-mode
  start/stop and the Doze-exemption ask.
- BackgroundService: dataSync foreground service + partial wake lock —
  holds the process (and the WebView WebSocket) open while the app is
  minimized; quiet persistent notification with a "Отключить фон" action.
  Notification channels: silent background presence, high-importance
  messages.
- Manifest: POST_NOTIFICATIONS / FOREGROUND_SERVICE(_DATA_SYNC) /
  WAKE_LOCK / REQUEST_IGNORE_BATTERY_OPTIMIZATIONS + service entry;
  notification tap resumes MainActivity (singleTask) into open_url.
- webclient: nativeBridge composable; usePush gets a bridge mode that
  replaces web-push entirely (settings toggle keeps working); chat store
  raises 'Navi ответила' through the bridge on stream end when the
  window is hidden. Fixed a latent undefined-variable in web syncState
  (notificationsSupported -> notifSupported()).
- New unit tests for the bridge surface; 147 frontend tests + APK build
  pass.

Merge remote-tracking branch 'origin/master' ...

# Conflicts:
#	webclient/vendor/gnexus-ui-kit/package-lock.json

webclient: settings tab polish, light chat-table styling, iOS launch screens ...

- Synapse tab icon was a no-op glyph: ph-diagram-project does not exist in
  the bundled Phosphor regular set — the button rendered bare text. Switched
  to ph-network, which ships.
- .settings-tabs capped at 1200px width on wide screens (was max-width:none).
- Chat markdown tables: the old .msg-assistant-content .table rules were
  dead (markdown never adds a .table class) — retarget .table-wrap table and
  restyle lightly: framed border + radius, muted header row, plain row
  separators, no uppercase/no hover color jump.
- iOS home-screen: apple-mobile-web-app metas and a full apple-touch-startup-
  image set (24 device classes, portrait+landscape) rendered from logo.svg
  on the theme background.

webclient: PWA hardening — stable height skeleton, touch selection policy, fixed maskable icons ...

- html/body/#app height via percentages instead of 100vh/dvh: the standalone
  PWA visual viewport drifts with keyboard/system panels, which let the
  document exceed the screen and scroll fixed headers away.
- viewport meta gains interactive-widget=resizes-content; phone-width inputs
  (textarea/text) are pinned to 16px to avoid mobile focus zoom.
- Selection policy: service chrome (chat header, sidebar, tab strip, input
  bar, meta rows) is unselectable with -webkit-touch-callout, killing the
  'Search with Google' sheet on long-press; message content and settings
  panels keep selectable text.
- Apple touch icon switched to a proper 180px tile.
- Regenerated maskable icons (were degenerate 1px-tall files): dark
  background plus the logo inside the 80% safe zone.
- manifest gains display_override.

webclient: fix mobile tab-block drift — column flex nowrap + stretch, kit table scrolls inside its wrapper

webclient: reveal the active settings tab when the mobile tab strip scrolls

webclient: settings header now literally the chat header; app-wide thin rounded scrollbars (override kit's thick square defaults)

webclient: exclusive radio groups in Synapse reactions (distinct names, kit options API); mobile sidebar row swaps close button after New Chat

webclient: settings page fits the app frame — flat chat-style header bar, single full-bleed scroll region, mobile adaptation (stacked MCP rows, viewport-safe modals)

webclient: MCP keys tab gets an empty-state when no server declares a user_key slot

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)
