Two fixes for Camanji rate limit UX:
1. api/streaming.py — pass fallback_model from profile config to AIAgent
The agent already supports fallback_model (a dict with provider/model/base_url)
for automatic rate-limit recovery, but streaming.py never read it from config
or passed it to AIAgent. Now reads get_config().get('fallback_model') at
call time (not module-level snapshot) and passes it through.
Also reads platform_toolsets.cli from the active profile's config at call
time so profiles with custom toolset lists use the right tools.
Camanji has fallback_model: {provider: openrouter, model: anthropic/claude-sonnet-4.6}
so hitting the direct-Anthropic rate limit will now automatically retry via
OpenRouter before giving up.
2. api/streaming.py + static/messages.js — show error inline, not 'Connection lost'
Previously: agent threw -> put('error', msg) -> SSE connection closed ->
browser's network-level 'error' event fired -> generic 'Connection lost'.
The actual error message was invisible to the user.
Fix: renamed server-side error event to 'apperror' (distinct from the SSE
spec's network error event). Added source.addEventListener('apperror', ...)
in messages.js that renders the error as a styled assistant message:
⏱️ Rate limit reached: <full message>
*Rate limit reached. Fallback model exhausted. Try again in a moment.*
Also added source.addEventListener('warning', ...) for non-fatal notices
(future use: fallback-activated status bar update).
Tests: 426 passed, 0 failed.
- index.html: btnSend hidden by default (display:none), icon-only (upward
arrow SVG, no text label), title attribute for accessibility
- style.css: new send-btn design — 34px circle, blue fill (#7cb9ff),
subtle glow box-shadow, scale() hover/active for tactile feel,
.send-btn.visible with @keyframes send-pop-in (scale+opacity spring
using cubic-bezier(.34,1.56,.64,1) for a satisfying pop). Mobile
override updated to preserve circle dimensions.
- ui.js: updateSendBtn() — shows button with pop-in animation when
textarea has content OR files are attached and agent is not busy;
hides instantly when content is cleared. Hooked into setBusy() and
renderTray() so button state tracks all content sources correctly.
- boot.js: input event listener calls updateSendBtn() on every keystroke.
- messages.js: autoResize() calls updateSendBtn() so button disappears
immediately after send clears the textarea.
- tests/test_sprint21.py: 33 tests covering HTML structure, CSS design
(circle shape, colors, animations, keyframes), JS logic (updateSendBtn,
setBusy, renderTray, autoResize integration), and regressions
(363 total, all pass).
Track A: Workspace breadcrumb navigation
- Breadcrumb path bar with clickable segments when inside subdirectories
- Up button in panel header for parent directory navigation
- S.currentDir state tracking; file ops stay in current directory
- New file/folder creation respects current subdirectory
Track B: Slash commands foundation
- New commands.js module (7th JS module) with command registry and parser
- Built-in commands: /help, /clear, /model, /workspace, /new
- Autocomplete dropdown on / input with arrow/tab/enter/escape navigation
- Unrecognized commands pass through to agent normally
Track C: Send key setting (closes#26)
- send_key added to settings defaults in api/config.py
- Settings panel dropdown: Enter (default) vs Ctrl/Cmd+Enter
- Keydown handler rewritten for autocomplete + send key preference
- Setting loaded on boot, persisted to settings.json
5 new tests, 242 total (219 passing, 22 pre-existing failures, 0 regressions).

The original PR correctly used new URL(path, location.origin) to strip
credentials from fetch/EventSource URLs, and added credentials:'include'
to all fetch() calls. However, EventSource requires { withCredentials: true }
as a second constructor argument for cookies/auth headers to be forwarded.
Without this, SSE streaming breaks behind a reverse proxy with basic auth.

When Hermes WebUI runs behind a reverse proxy with HTTP basic auth
(e.g. Caddy basic_auth), browsers embed credentials in the page URL.
The Fetch API and EventSource reject requests constructed from URLs
that include credentials (per Fetch spec, all modern browsers).
Fix: construct all fetch() and EventSource URLs via
new URL(path, location.origin) which strips credentials from the
base URL. Add credentials:"include" to ensure auth headers are
forwarded on each request.
