When submitting a message without a model/session configured, the
error path showed a help message but never cleared the textarea,
leaving the user's text stuck in the input field. Clear the input
and trigger autoResize on both the no-default-model and catch paths.
Fixes#1475

deleteMessage() bailed at `if (!sessionId) return;`, so the "x" on an output
shown before a model/API was selected did nothing — there's no session yet
(issue #1428). The session id is only needed for the server-side delete; without
one (or with no persisted message ids) we now fall through to removing the DOM,
so the "x" always at least dismisses the bubble.

CJK and other IME users confirm a candidate from the input-method popup by pressing Enter. The chat composer and the in-place message editor each bind a keydown handler that treats Enter (without Shift) as "submit", but they did not exclude the composition state. Pressing Enter to accept an IME candidate therefore sent the half-composed text (e.g. a stray "ce's") instead of just confirming the candidate.
These textareas intentionally hijack Enter to submit (Enter sends, Shift+Enter inserts a newline), which bypasses the browser's native form submission and the IME guard that comes with it, so the guard has to be re-added explicitly.
Add '&& !e.isComposing' to the three Enter-to-submit handlers: static/app.js (the main composer's button-submit path and its send/new-chat path) and static/js/chat.js (the editor for an already-sent message). Normal Enter (isComposing false) still submits; Shift+Enter still inserts a newline.
Tested: node --check on both files; manually verified with a Chinese IME that pressing Enter to pick a candidate no longer sends, and a message is sent only after composition ends.
* Accessibility: ARIA labels and toggle states
Screen readers couldn't name several icon-only controls or tell whether the
tool toggles were on. This adds accessible names and exposes toggle state,
with no behavior or layout change.
- Icon-only buttons get aria-label: web/shell tool toggles, the "more tools"
overflow button (+ aria-haspopup), and the color-reset buttons.
- Unlabeled inputs/selects get aria-label: memory + skills search, model-picker
search, memory sort, theme font/density selects, and the new-memory / skill
(title, when-to-use, how, tags) fields, which only had a visual floating label.
- Toggle state via aria-pressed, kept in sync at the existing .active write
sites: web/shell toggles (setupToggle) and the Agent/Chat mode buttons
(initModeToggle). Static aria-pressed added in the markup so the attribute
exists before JS runs.
Scope: first slice of the ROADMAP accessibility pass. Focus-visible/contrast,
reduced-motion, and modal dialog roles/focus-trap are left for follow-ups.
Checks: node --check static/app.js. No Python touched.
* Accessibility: mark chat log busy while streaming
The chat log is an aria-live="polite" region, so streaming a response
token-by-token made screen readers announce every partial update — noisy and
unreadable. Set aria-busy="true" on #chat-history while a response streams and
back to "false" in the stream's finally block. Assistive tech then waits for
the settled message and announces it once.
Checks: node --check static/js/chat.js.
* fix(stream): read 'reasoning' SSE field for vLLM 0.20.2 / NIM
vLLM 0.20.2 / NVIDIA NIM emit reasoning-parser output in the `reasoning` delta field; older builds use `reasoning_content`. stream_llm() read only the latter, so reasoning from models like Nemotron-3-Nano (--reasoning-parser) was silently dropped and never rendered. Accept either field.

* fix(agent): keep reasoning_content only on the latest assistant turn
The agent loop echoed each round's reasoning back as `reasoning_content` on every assistant turn, assuming vendors ignore it. Nemotron's chat template re-injects ALL prior reasoning_content as <think> blocks, and the loop is trimmed only once (before it starts) — so reasoning accumulated unbounded across rounds, bloating context and feeding the model its own prior reasoning, which reinforced repetition/looping. Strip reasoning_content from earlier assistant turns so only the most recent round carries it (still satisfies DeepSeek's thinking-mode follow-up requirement).

* fix(agent-ui): wrap each round's reasoning in its own <think> block
The streamed think-tag wrapper gated on whole-message substring checks (accumulated.includes('<think>')), which only ever wrapped ONE reasoning block per message. A multi-round agent response has a reasoning phase per round, so once round 1 closed its <think>...</think>, rounds 2+ reasoning was emitted unwrapped and leaked into the visible answer. Replace the substring checks with a stateful open/close flag that toggles per think/answer cycle, so each round's reasoning gets its own collapsible block. Single-turn chat is unchanged (one open, one close).

* test(stream): reasoning/reasoning_content delta surfaces as thinking chunk
Covers @pewdiepie-archdaemon's requested regression: a streamed {reasoning: ...} delta emits a thinking chunk while {content: ...} streams as normal content; plus the older reasoning_content field for backward compat. Mirrors the #591 scenario.

When the selected model fails before producing output, stream_llm_with_fallback
quietly switches to the next candidate and the reply is shown under the
originally selected model's name, so a misconfigured provider looks like it
works. (Concretely: a Bedrock gateway that 400s every Anthropic/Claude request
appears fine because another model silently answers under the Claude label.)
Emit a `fallback` SSE event ({selected_model, answered_by, reason}) the first
time a non-primary candidate produces output, forward it through the agent loop
and both chat-route paths, stamp the response metrics with the model that
actually answered, and show a notice + relabel the reply in the UI.
Tested: python -m pytest tests/test_llm_core_fallback.py (3 pass);
python -m py_compile src/llm_core.py src/agent_loop.py routes/chat_routes.py;
node --check static/js/chat.js.
Typing / in the chat composer now shows a filtered popup listing all
available commands with their description. Arrow keys or Tab to select,
Enter/Tab to insert, Esc to close, click also works.
- New module: static/js/slashAutocomplete.js
Reads the existing COMMANDS registry (and LEGACY_ALIASES) from
slashCommands.js — no command logic added here, just discovery UI.
Excludes easter-egg commands (flip, roll, 8ball, fortune, odyssey,
ascii). Promotes short legacy aliases (/new, /clear, /web, /compact,
/research, etc.) as first-class rows so users don't have to know the
full /session new form.
- slashCommands.js: export COMMANDS and LEGACY_ALIASES so the new
module can read the registry.
- chat.js: lazy-import slashAutocomplete on init, wire to #message
textarea.
- style.css: popup + row styles using existing CSS variables.
