Pull request overview

This PR bundles a broad set of sprint changes spanning a reference “context management” Python module + docs, frontend accessibility/UI upgrades (including demo flows), SSE client refactor, and infrastructure/security hardening.

Changes:

• Add contextkit reference module (budgets X/Y, rolling summary, skills registry, tool artifact handling, RAG evidence packs, graph memory) and accompanying playbook/docs/templates.
• Frontend a11y/UX upgrades (focus styles, motor toolbar, persona explainer/status badge, theme compare slider, i18n strings), plus extensive Vitest coverage.
• Security/infrastructure updates (demo-login JWT flow, docker-compose port binding hardening, CI audits set to fail, dependency bumps).

• Tuple is imported but not used in this module. Removing it avoids lint noise and keeps the reference implementation clean.

from typing import Tuple

frontend/src/lib/sse-fetch.ts:109

• For non-OK responses (e.g., 401/403/500) the function returns silently, which can make callers treat failures as normal stream termination. Consider throwing an error (or calling onerror) when !response.ok, and also handle the !response.body case explicitly so SSE failures are surfaced reliably.

  // If the response isn't OK and onopen didn't throw, bail out
  if (!response.ok || !response.body) return

frontend/src/lib/sse-fetch.ts:8

• The header comment claims support for automatic retry with back-off, and openWhenHidden, but the implementation does not implement retries/backoff or any visibility handling. Either implement the promised behaviors or update the comment/API docs to match actual supported features.

/**
 * Lightweight SSE client using native fetch + ReadableStream.
 * Drop-in replacement for @microsoft/fetch-event-source with the same
 * callback-based API but zero external dependencies.
 *
 * Supports POST (and any HTTP method), custom headers, AbortController,

• SSE commonly uses CRLF (\\r\\n) line endings per spec. Splitting only on \\n / \\n\\n can cause parsing issues (e.g., fields include trailing \\r, event boundaries aren’t detected). Normalize newlines (e.g., replace \\r\\n with \\n) or split using \\r?\\n and \\r?\\n\\r?\\n patterns.

  for (const raw of block.split('\n')) {

• SSE commonly uses CRLF (\\r\\n) line endings per spec. Splitting only on \\n / \\n\\n can cause parsing issues (e.g., fields include trailing \\r, event boundaries aren’t detected). Normalize newlines (e.g., replace \\r\\n with \\n) or split using \\r?\\n and \\r?\\n\\r?\\n patterns.

frontend/src/components/accessibility/preferences-panel.tsx:72

• Focus restore now only happens when open transitions to false. If the panel unmounts while still open (e.g., navigation/route change), focus won’t be restored. Consider adding a cleanup that restores focus on unmount when open is true and previousFocusRef.current is set, to preserve expected keyboard accessibility.

  useEffect(() => {
    if (open) {
      previousFocusRef.current = document.activeElement as HTMLElement | null
    } else if (previousFocusRef.current) {
      previousFocusRef.current.focus()
      previousFocusRef.current = null
    }
  }, [open])

frontend/src/stores/auth-store.test.ts:117

• This test does not actually validate rehydration behavior (it has no assertion that user was cleared; it also doesn’t trigger zustand persist rehydration, and the expect(true).toBe(true) is a no-op). Recommend asserting the observable outcome by triggering rehydration (e.g., re-importing the store after setting localStorage, or exposing/forcing persist rehydrate in the test) and then checking user === null when token is absent.

  it('onRehydrate clears stale user when token is absent', () => {
    // Simulate stale persisted state (user present, token absent)
    localStorage.setItem(
      'ailine-auth',
      JSON.stringify({
        state: { user: MOCK_USER },
        version: 0,
      }),
    )

    // Force rehydration by re-creating store state
    // The onRehydrateStorage callback should clear user when token is null
    const state = useAuthStore.getState()
    // After rehydration without token, user should be wiped
    if (!state.token && state.user) {
      // This simulates the rehydration logic
      expect(true).toBe(true) // The store handles this internally
    }
  })

.env.example:75

• The example environment enables AILINE_DEV_MODE and AILINE_DEMO_MODE by default while leaving AILINE_JWT_SECRET empty. If someone uses this as a baseline for a real deployment, it increases the chance of running with insecure auth bypass/demo features. Consider defaulting dev/demo flags to false in the example, and/or adding a prominent warning comment near these variables that production must set a strong JWT secret and disable dev/demo modes.

AILINE_JWT_SECRET=""

# === Dev Mode (enables X-Teacher-ID header bypass for local dev) ===
AILINE_DEV_MODE="true"

# === Demo Mode (enables /demo/* endpoints and demo login) ===
AILINE_DEMO_MODE="1"

Artifact filenames are built directly from tool_name. If tool_name can contain path separators or .., this can lead to writing outside artifacts_dir or failing on invalid filenames. Sanitize tool_name (e.g., allowlist [A-Za-z0-9_-], replace others with _, and cap length) before constructing the path.
