* chore: relicense BUSL-1.1 -> Apache 2.0 for 1.6.0
Flips every license artifact in the tree; 1.5.x and earlier remain
BUSL-1.1 per their release-time LICENSE files. Contributor consent
record: #548 (rationale: #546).
- LICENSE: canonical Apache 2.0 text
- NOTICE: new; copyright line + pointer to THIRD-PARTY-NOTICES
- pyproject.toml: SPDX expression + explicit license-files trio
- Dockerfile: COPY the license trio (hatchling needs them at build)
- THIRD-PARTY-NOTICES: BUSL line reworded; bundled-version drift
fixed (KaTeX 0.17.0, Mermaid 11.15.0, hls.js 1.6.16)
- README badge + License section, CONTRIBUTING inbound-license line,
TS SDK package(+lock), example pyproject
- docs/pgbouncer.md: drop stray ':' introduced in #353
* docs: add CONTRIBUTORS.md
* chore: drop LICENSE leading blank line
The apache.org LICENSE-2.0.txt begins with a newline; the SPDX
canonical text and GitHub license templates do not. Use the
conventional form — detection is whitespace-normalized either way.
* feat: render rich media embeds for MCP tool results
Detect structured media JSON (stream_url, results, sessions) in MCP
tool output and render interactive cards instead of plain text.
Web UI: media cards with thumbnail, title, metadata, and click-to-play
video/audio. HLS via lazy-loaded hls.js with direct-stream preference.
Collapsed raw JSON (API keys redacted) for inspection.
Discord: rich embeds with proxied thumbnail images (fetched by the bot
since Discord CDN cannot reach private media servers). Search results
as numbered lists, session state as "Now Playing" cards. Stream URLs
never exposed in embeds — web_url used for safe clickable links.
CI: vendor hls.js 1.6.15 with renovate tracking and update script.
* fix: address PR #292 review — SSRF guards, streaming fetch, tests
- URL validation: reject non-http(s) schemes and userinfo in thumbnail
URLs. Private IPs intentionally allowed (media servers are on LAN).
- Streaming fetch: use http.stream() with aiter_bytes() and a running
byte count to enforce the 2MB cap without buffering the full response.
Validate content-type is image/* before downloading.
- Resilience: wrap try_build_media_embed in try/except in bot.py so a
media embed failure falls through to the code-block path.
- LICENSE: download hls.js LICENSE from npm on update instead of only
copying from old dir.
- Tests: add 19 new tests — try_parse_media (8 cases), _is_safe_image_url
(7 cases), embed builders (4 cases including stream_url exclusion and
string season/episode safety).
* chore: add LICENSE file for vendored hls.js
* fix: remove ANSI escape codes from tool preview fields
Preview text (tool args, URLs, queries) was wrapped in DIM/RESET ANSI
codes at the source in session.py, which leaked into SSE events and
rendered as raw escape sequences in Discord and the web UI.
Move ANSI styling to the CLI consumer (cli.py) where it belongs. Also
escape markdown in Discord tool name titles to prevent __ from being
interpreted as underline formatting.
* fix: drop [MCP: server] prefix from tool descriptions
The prefix made MCP tools look second-class compared to builtins,
causing models to hesitate using them. The server name is already
encoded in the tool name (mcp__server__tool).
* feat: pretty-print JSON tool output, player error state, broader key redaction
- JSON tool results are detected and pretty-printed with 2-space indent
instead of rendering as a wall of text
- API key redaction extended to cover api_key, apiKey, api-key, and
token query params across all tool output (not just media embeds)
- Video/audio player shows styled error message when stream fails to
load instead of leaving a broken player element
- Both appendToolOutput and replayHistory use shared renderToolOutput()
* fix: designer review — player error retry, contrast, tool-cmd cap
- Player error: role="alert" for screen readers, retry button that
reuses existing play handler, includes media title in error message
- Light theme: darken --red from #dc2626 to #b91c1c (5.7:1 contrast
on --code-bg, was 4.3:1 failing WCAG AA at 12px)
- Pretty-print collapsed raw JSON in media embeds (was missed earlier)
- Cap .tool-cmd at 120px to prevent tools with many args from making
approval blocks disproportionately tall in history replay
- Dedicated .media-player-error class instead of reusing .tool-output
* fix: Discord tool info name matching regression, suppress deprecation warning
The escape_markdown call on tool names was stored for matching against
ToolResultEvent.name, but event.name is raw/unescaped. The escaped name
never matched, so the "Running → Done" transition silently failed and
previews disappeared from the status embed.
Fix: store raw name for matching, use escaped name only for display.
Also suppress discord.py's re.sub count deprecation warning (Python
3.13+ issue, fixed upstream).
* fix: update MCP tool description tests to match prefix removal
* fix: address PR #292 review round 2
- Retry button: handle missing span children in click handler so retry
buttons from player error state don't throw
- Footer count: use len(lines) instead of min(len(results), 10) to
reflect actual rendered count after char budget truncation
- Null display: use "null" instead of "None" in JS tool arg preview
- Broader redaction: also redact JSON "api_key": "..." patterns
- SSRF hardening: block loopback and link-local IPs plus cloud metadata
hostnames in thumbnail fetch (private LAN IPs still allowed)
* feat: mermaid diagram rendering with lazy loading and theme integration
Integrate mermaid.js 11.13.0 (self-hosted, MIT, ~2.9MB) for rendering
```mermaid code blocks as inline SVG diagrams. Covers flowcharts,
sequence, class, ER, state, gantt, pie, timeline, and mindmap.
- Lazy-loaded via dynamic script injection on first mermaid block
detection (not eagerly loaded on every page view)
- 3-state loader (idle/loading/ready) with callback queue
- Serialized rendering to avoid mermaid internal state corruption
- Theme integration via getComputedStyle reading CSS design tokens;
re-renders all diagrams on dark/light theme toggle
- Source preserved in data-mermaid-source for theme re-rendering
- Error handling with source code fallback display
- securityLevel: "strict" (DOMPurify) for SVG XSS prevention
- THIRD-PARTY-NOTICES updated with mermaid MIT license
* fix: mermaid render fixes from Copilot review
- Call result.bindFunctions(container) after SVG insertion for
interactive diagram elements (click handlers, links, tooltips)
- Clear mermaid-error class on successful render (fixes stale error
styling after theme toggle re-render)
- Clear mermaid-error in reRenderAllMermaid before re-render sequence
- Restructure postRenderMarkdown so mermaid rendering runs even when
highlight.js is unavailable (hljs guard changed from early return
to conditional block)
