Summary

  • Landing page — standalone HTML at site root with Tailwind CSS dark theme, hero, code showcase, LangChain comparison table, feature grid, persona cards, and getting started section
  • SECURITY.md — root-level vulnerability disclosure policy (triggers GitHub's Security Policy badge)
  • NichevLabs branding — "open source from NichevLabs" across README, docs, pyproject.toml, and landing page
  • Docs workflow — updated to copy landing page as site/index.html after MkDocs build
  • .private/ gitignored for local-only assets (social preview, growth plan, comparison drafts)

Test plan

  • Verify MkDocs build still passes (mkdocs build)
  • Verify landing page renders correctly at site root
  • Verify docs pages still accessible at existing paths (e.g., /QUICKSTART/, /modules/AGENT/)
  • Verify "Docs" links on landing page point to correct MkDocs pages
  • Verify GitHub shows Security Policy badge from root SECURITY.md

fix: batch 1 — 13 critical bug fixes from bug hunt
6268b32 
Security:
- Path traversal in JsonFileSessionStore — validate session_id (#9)
- Unicode homoglyph bypass in injection screening — NFKD + zero-width
  strip + homoglyph map (#13)

Data integrity:
- FileKnowledgeStore._save_all() atomic write via tmp + os.replace (#10)
- JsonFileSessionStore.save() atomic write (#31)

Agent core:
- astream() uses self._effective_model (was self.config.model) (#1)
- Sync _check_policy rejects async confirm_action with clear error (#2)
- Sync _streaming_call isinstance(chunk, str) guard (#18)

Providers:
- FallbackProvider stream()/astream() record success after consumption,
  not before — circuit breaker now works for streaming (#3)
- Gemini response.text ValueError catch for tool-call-only responses (#4)

Tools:
- aexecute() uses run_in_executor(None) shared executor (#5)
- execute() awaits coroutines from async tools via asyncio.run (#6)

RAG:
- Hybrid search O(n²) → O(1) via text_to_key dict lookup (#7)
- SQLiteVectorStore thread safety + WAL mode (#8)

Evals:
- OutputEvaluator catches re.error on invalid regex (#11)
- JsonValidityEvaluator respects expect_json=False (#12)

16 new regression tests. Full suite: 2000 passed.

fix(landing): mobile iteration 2 — pointer:coarse, copy, layout polish
3cb1086 
Addresses the 10 issues from Galaxy S23 testing after PR #41.

Critical: header still showed full nav on mobile because Chrome's "Desktop
Site" mode reports a viewport of ~1280px (not ~980px as initially assumed),
which exceeded the 1024px breakpoint added in PR #41. The fix is to detect
touch input via `@media (pointer: coarse)`, which the Desktop Site toggle
cannot override. This is the only reliable signal for "this is a touch
device, no matter what the viewport pretends to be."

Issues fixed:

1. **Header nav still showing on mobile** — Added @media (pointer: coarse)
   block that forces hamburger + drawer regardless of reported viewport.
   Also removes nav-hide-on-scroll on touch (issue #10): the auto-hide
   stays as a desktop progressive enhancement only.

2. **Hero pill grid felt templated** — Replaced 8 generic pills with a
   cleaner "Works with · OpenAI Anthropic Gemini Ollama" provider strip.
   Each provider gets a small cyan dot prefix. Removed the redundant
   feature pills (Multi-Agent Graphs, 50 Evaluators, etc.) since they
   already appear in the dedicated features section below.

3. **Supervisor agent chips broke into 3+1 layout** — Switched .sim-agents
   to a 2-column CSS grid with `:last-child:nth-child(odd)` selector that
   spans the orphaned last item across both columns. Handles 2/3/4 agent
   counts gracefully.

4. **"What is Selectools?" copy too dense** — Restructured into 3 short
   paragraphs with a visually distinct middle line listing capabilities
   separated by middle-dots. Removed the redundant "Unlike LangChain..."
   framing (the comparison tables already make this case). Closing
   paragraph keeps the brand voice.

5. **Code block scroll indicator** — Added a right-edge gradient mask to
   .code-body matching the comparison table pattern. Signals "more content
   this way" for horizontally-scrollable code. Mask drops on hover/focus
   so users see the full content when engaging. Also reduced code font
   slightly on mobile (12px → 11.5px) for better fit.

6. **Feature cards too tall on mobile** — Compact card layout under
   @media (max-width: 768px), (pointer: coarse): 28px → 20px padding,
   40 → 32px icon, 32 → 14px grid gap. Cards now feel like a tight
   group instead of 1/3-screen blocks with awkward gaps.

7. **"Live · no server required" chip orphaned** — Moved inline with the
   "Visual Agent Builder" section label so it reads as a header annotation
   rather than a floating chip between the description and the card.

8. **Comparison table cells wrapping to 3 lines** — Bumped .cmp-table
   min-width from 640px to 800px so each column has ~115px (enough for
   "macOS desktop app" and "No (desktop only)" to fit on 1-2 lines).
   Added `white-space: nowrap` to .yes/.no/.mid verdict cells so 2-3 char
   answers never wrap awkwardly.

9. **No gap before first builder card in "Three paths"** — Added explicit
   margin-bottom: 64px on the section description and padding-top: 8px
   on the cards container.

10. **Header should always be visible** — Removed the hide-on-scroll-down
    behavior on touch devices (kept on desktop where it's a thoughtful
    progressive enhancement). On mobile the nav now stays fixed at the
    top throughout scrolling, which doubles as a wayfinding aid.

Approach informed by /adapt and /clarify skill guidelines. The
@media (pointer: coarse) pattern is the key insight from /adapt:
viewport-based responsive design is fundamentally fragile because users
can override it (Desktop Site mode, Reader Mode, browser zoom). Touch
input is a hardware property that cannot be spoofed.
