Hermes Web UI — Sprints 11-14: multi-provider models, settings, session QoL, alerts, polish
Sprint 11 (v0.13): multi-provider model support, streaming smoothness - Dynamic model dropdown populated from configured API keys (OpenAI, Anthropic, Google, DeepSeek, GLM, Kimi, MiniMax, OpenRouter, Nous Portal) - Scroll pinning during streaming (no forced scroll when user has scrolled up) - All route handlers extracted to api/routes.py (server.py now ~76 lines) Sprint 12 (v0.14): settings panel, SSE reconnect, session QoL - Settings panel (gear icon) -- persist default model and workspace server-side - SSE auto-reconnect on network blips - Pin/star sessions to top of sidebar - Import session from JSON export Sprint 13 (v0.15): cron alerts, background errors, session duplicate, tab title - Cron completion alerts: toast per completion + unread badge on Tasks tab - Background agent error banner when a non-active session errors mid-stream - Session duplicate button - Browser tab title reflects active session name Sprint 14 (v0.16): Mermaid diagrams, file ops, session archive/tags, timestamps - Mermaid diagram rendering inline (dark theme, lazy CDN load) - File rename (double-click in file tree) and create folder - Session archive (hide without deleting, toggle to show) - Session tags -- #hashtag in title becomes colored chip + click-to-filter - Message timestamps (HH:MM on hover, full date as tooltip) Test suite: 224 tests across 14 sprint files + regression gate, 0 failures.

## [v0.1.0] Concurrency + Correctness Sweeps
|
||||
## [v0.16] Sprint 14 -- Visual Polish + Workspace Ops + Session Organization
|
||||
*March 30, 2026 | 233 tests*
|
||||
|
||||
### Features
|
||||
- **Mermaid diagram rendering.** Code blocks tagged `mermaid` render as
|
||||
diagrams inline. Mermaid.js loaded lazily from CDN on first encounter.
|
||||
Dark theme with matching colors. Falls back to code block on parse error.
|
||||
- **Message timestamps.** Subtle HH:MM time next to each role label. Full
|
||||
date/time on hover tooltip. User messages get `_ts` field when sent.
|
||||
- **File rename.** Double-click any filename in workspace panel to rename
|
||||
inline. `POST /api/file/rename` endpoint with path traversal protection.
|
||||
- **Folder create.** Folder icon button in workspace panel header. Prompt
|
||||
for name, `POST /api/file/create-dir` endpoint.
|
||||
- **Session tags.** Add `#tag` to session titles. Tags shown as colored
|
||||
chips in sidebar. Click a tag to filter the session list.
|
||||
- **Session archive.** Archive icon on each session. Archived sessions
|
||||
hidden by default; "Show N archived" toggle at top of list. Backend
|
||||
`POST /api/session/archive` with `archived` field on Session model.
|
||||
|
||||
### Bug Fixes
|
||||
- **Date grouping fix.** Session list groups (Today/Yesterday/Earlier) now
|
||||
use `created_at` instead of `updated_at`, preventing sessions from jumping
|
||||
between groups when auto-titling touches `updated_at`.

## [v0.15] Sprint 13 -- Alerts + Session QoL + Polish
|
||||
*March 30, 2026 | 221 tests*
|
||||
|
||||
### Features
|
||||
- **Cron completion alerts.** New `GET /api/crons/recent` endpoint. UI polls every
|
||||
30s (pauses when tab is hidden). Toast notification per completion with status icon.
|
||||
Red badge count on Tasks nav tab, cleared when tab is opened.
|
||||
- **Background agent error alerts.** When a streaming session errors out and the user
|
||||
is viewing a different session, a persistent red banner appears above the messages:
|
||||
"Session X has encountered an error." View button navigates, Dismiss clears.
|
||||
- **Session duplicate.** Copy icon on each session in the sidebar (visible on hover).
|
||||
Creates a new session with the same workspace and model, titled "(copy)".
|
||||
- **Browser tab title.** `document.title` updates to show the active session title
|
||||
(e.g. "My Task -- Hermes"). Resets to "Hermes" when no session is active.
|
||||
|
||||
### Bug Fixes
|
||||
- Click guard added for duplicate button to prevent accidental session navigation.

## [v0.14] Sprint 12 -- Settings Panel + Reliability + Session QoL
|
||||
*March 30, 2026 | 211 tests*
|
||||
|
||||
### Features
|
||||
- **Settings panel.** Gear icon in topbar opens slide-in overlay. Persist default
|
||||
model and workspace server-side in `settings.json`. Server reads on startup.
|
||||
- **SSE auto-reconnect.** When EventSource drops mid-stream, attempts one reconnect
|
||||
using the same stream_id after 1.5s. Shared `_wireSSE()` function eliminates
|
||||
handler duplication.
|
||||
- **Pin sessions.** Star icon on each session. Pinned sessions float to top of sidebar
|
||||
under a gold "Pinned" header. Persisted in session JSON.
|
||||
- **Import session from JSON.** Upload button in sidebar. Creates new session with
|
||||
fresh ID from exported JSON file.
|
||||
|
||||
### Bug Fixes
|
||||
- `models.py` uses `_cfg.DEFAULT_MODEL` module reference so `save_settings()` changes
|
||||
take effect for `new_session()`.
|
||||
- Full-scan fallback sort in `all_sessions()` now accounts for pinned sessions.
|
||||
- `save_settings()` whitelists known keys only, rejecting arbitrary data.
|
||||
- Escape key closes settings overlay.

## [v0.13] Sprint 11 -- Multi-Provider Models + Streaming Smoothness
|
||||
*March 30, 2026 | 201 tests*
|
||||
|
||||
### Features
|
||||
- **Multi-provider model support.** New `GET /api/models` endpoint discovers configured
|
||||
providers from `config.yaml`, `auth.json`, and API key environment variables. The model
|
||||
dropdown now populates dynamically from whatever providers the user has set up (Anthropic,
|
||||
OpenAI, Google, DeepSeek, Nous Portal, OpenRouter, etc.). Falls back to the hardcoded
|
||||
OpenRouter list when no providers are detected. Sessions with unlisted models auto-add
|
||||
them to the dropdown.
|
||||
- **Smooth scroll pinning.** During streaming, auto-scroll only when the user is near the
|
||||
bottom of the message area. If the user scrolls up to read earlier content, new tokens
|
||||
no longer yank them back down. Pinning resumes when they scroll back to the bottom.
|
||||
|
||||
### Architecture
|
||||
- **Routes extracted to api/routes.py.** All 49 GET/POST route handlers moved from server.py
|
||||
into `api/routes.py` (802 lines). server.py is now a 76-line thin shell: Handler class
|
||||
with structured logging, dispatch to `handle_get()`/`handle_post()`, and `main()`.
|
||||
Completes the server split started in Sprint 10.
|
||||
- **Cleaned up duplicate dead-code routes** that existed in the old `do_GET` (skills/save,
|
||||
skills/delete, memory/write were duplicated in both GET and POST handlers).
|
||||
|
||||
### Bug Fixes
|
||||
- Regression tests updated for new route module structure.
