Release v1.7.18: fix Alpine.js SRI + CSP, add frontend modernization roadmap

- Revert @alpinejs/csp (CSP build has no support for template literals,
  optional chaining, or x-html — all used in the app template); switch
  back to the regular alpinejs build
- Pin Alpine.js to 3.15.12 with a verified SRI hash (replaces the
  floating @3.x.x tag that caused the integrity check failure)
- Restore 'unsafe-eval' to script-src (required by Alpine.js's
  new Function() expression evaluator; inline script was already
  eliminated in v1.7.17 so 'unsafe-inline' stays removed)
- Add Phase 7.5 Frontend Modernization to ROADMAP: Vue 3 + Vite
  migration plan that will allow a clean CSP without unsafe-eval

+# AOC v1.7.16 Release Notes
+
+**Release Date:** 2026-04-24
+
+## Infrastructure & Maintenance
+
+### Gitea Actions CI Fix
+
+The CI workflow (`.gitea/workflows/ci.yml`) has been reworked for compatibility with Gitea Actions (`act_runner`):
+
+- **Removed** `actions/setup-python@v5` — incompatible with self-hosted Gitea (relies on GitHub's tool cache API)
+- **Added** system Python installation via `apt-get install python3 python3-venv`
+- **Uses a virtual environment** inside the job to avoid PEP 668 `externally-managed-environment` errors
+- All steps (`pip install`, `ruff check`, `ruff format`, `pytest`) now activate the venv explicitly
+
+### Repository Cleanup
+
+- **Expanded `.gitignore`** to cover all venv variants (`.*venv*/`), `.ruff_cache/`, and common temp/backup files
+- **Removed** temporary working directories (`backend/.venv_ci/`, `__pycache__/`)
+
+## Files Changed
+
+| File | Change |
+|------|--------|
+| `.gitea/workflows/ci.yml` | Complete rewrite for Gitea Actions compatibility |
+| `.gitignore` | Expanded patterns for venvs, caches, temp files |
+| `VERSION` | Bumped to 1.7.16 |
+
+## Test Results
+
+- **80/80 pytest tests passing**
+- Ruff lint/format clean
+- CI green on Gitea Actions

+
+## Security & Hardening
+
+### Alpine.js CSP Build
+
+The frontend now loads the **Alpine.js CSP build** (`@alpinejs/csp@3.15.12`) instead of the standard distribution. This aligns the runtime with the existing Content-Security-Policy and removes reliance on `unsafe-eval` for Alpine's expression evaluation.
+
+- **File:** `backend/frontend/index.html`
+- **Integrity hash:** `sha384-MKLWq9B+VC0W3U8kDIBEsSu8uCnQ1B0UQpRaB+F7uR5ocXFbymMUKuLRntu5LLdu`
+
+## Ingestion Reliability
+
+### Office 365 Management Activity API Window Clamping
+
+The unified audit log fetcher now respects the API's hard limits to prevent rejected requests during catch-up scenarios or stale watermarks:
+
+- **Maximum query window:** 24 hours (`_API_MAX_WINDOW_HOURS`)
+- **Maximum lookback:** 7 days (`_API_MAX_LOOKBACK_DAYS`)
+- When a persisted `since` watermark is older than either limit, the start time is clamped to the most recent allowable window. Subsequent fetches continue catching up normally.
+
+This prevents ingestion stalls after extended outages without dropping events permanently.
+
+## Files Changed
+
+| File | Change |
+|------|--------|
+| `backend/frontend/index.html` | Switched Alpine.js to CSP build with updated SRI hash |
+| `backend/sources/unified_audit.py` | Added API window/lookback clamping for O365 Management Activity API |
+| `VERSION` | Bumped to 1.7.17 |

+## Phase 7.5: Frontend Modernization 📋
+Goal: eliminate `unsafe-eval` from the Content Security Policy by migrating from Alpine.js to a compiled frontend framework.
+
+Status: **Planned**. Current Alpine.js requires `unsafe-eval` because it uses `new Function()` to evaluate attribute expressions at runtime. A compiled framework evaluates all expressions at build time — the browser only receives static JS, making a fully clean CSP (`script-src 'self'`) possible.
+
+### Recommended approach: Vue 3 + Vite
+Alpine.js was inspired by Vue, so the migration is largely mechanical:
+
+| Alpine.js | Vue 3 |
+|-----------|-------|
+| `x-data="aocApp()"` | `<script setup>` or `createApp(aocApp)` |
+| `x-text`, `x-show`, `x-if`, `x-for` | `v-text`, `v-show`, `v-if`, `v-for` |
+| `x-model`, `x-html` | `v-model`, `v-html` |
+| `@click="method()"` | `@click="method()"` (identical) |
+
+The `app.js` logic (`aocApp()` function body, ~820 lines) translates almost directly.
+The CDN dependencies on `cdn.jsdelivr.net` and `alcdn.msauth.net` can be dropped:
+MSAL can be bundled via npm, and the final CSP becomes `script-src 'self'` only.
+
+### Effort estimate
+- Vite + Vue 3 project setup: ~2–3 hours
+- Template migration (HTML directives): ~4–6 hours
+- `app.js` → Vue component: ~2–3 hours
+- MSAL integration via npm: ~1 hour
+- Testing + polish: ~2–4 hours
+
+**Total: ~1–2 days**
+
+---
+
 ## Phase 7: Multi-Tenancy (Premium) ⏸️
 Goal: allow MSPs to manage multiple client tenants from a single deployment.
