Each (category × period) cell in news_digest.json now carries a hash of its
entry pool (sorted URLs). Before calling Gemini, the engine checks:
1. Hash matches stored hash (same inventory entries)
2. Last analyzed within MAX_STALENESS_DAYS=30
Both conditions true → reuse existing ranked list, 0 Gemini API calls.
Only cells where the inventory actually changed (new/removed entries) trigger
a fresh Gemini ranking.
Expected savings: re-runs with code-only changes → 0 API calls (down from 66).
New ingestion batch → only affected categories call Gemini (5-10 of 26 typical).
Stale refresh (>30d) → full refresh at most once per month.
Also:
- Remove day-level GitHub Actions cache for digest (redundant: news_digest.json
is committed to the repo and is the persistent store for _meta)
- Always run news_digest.py in both 04.1 and 09 workflows (it's cheap when 0
Gemini calls are needed)
- Trending badge now reads _meta.last_updated (actual analysis date) instead of
file mtime (which changes on every render/commit)
- Remove invalid extra_head key from v2-mkdocs.yml (left over from rollback)

Publisher and weekly digest workflows now restore news_digest.json from
GitHub Actions cache using key news-digest-YYYY-MM-DD. If cache hits
(same-day re-run after publisher failure), the Gemini digest step is
skipped entirely — saving ~20min and Gemini API credits.
Cache is saved immediately after successful generation and expires
automatically after 7 days (GitHub Actions cache policy).

1. geo_region inference: _infer_geo_from_url() infers Americas/Europe/España/Asia-Pacific
from URL TLD (.es .de .fr .uk .jp .cn etc.) as fallback when geo_region field is empty.
Industry digest now shows real content instead of empty categories.
2. Last-updated badge: trending section header now shows "Updated Jun 19, 2026" pill
derived from news_digest.json mtime — gives readers confidence in freshness.
3. Search boost: tech-digest and industry-digest pages now have search.boost: 2
frontmatter so they rank higher in MkDocs Material site search.
4. RSS feed (src/rss_generator.py): generates v2-docs/feed.xml with top-20 curated
picks from 3-month digest. Runs after news_digest in publisher. Autodiscovery
<link rel="alternate"> added to v2-mkdocs.yml extra_head.
5. Weekly cron (09.weekly_digest.yml): runs every Monday 06:00 UTC, generates digest
with Gemini, renders digest pages, commits, then triggers publisher.
