When a product no longer appears in a successful scrape for its
retailer+caliber, mark it out of stock. After each scrape cycle, hard
delete any product whose last_seen_at is older than 30 days (snapshots
cascade via FK). A zero-result scrape leaves existing listings alone so
a parse failure or transient site glitch can't nuke the catalog.
- Show "No price history available for this range yet." overlay when
the caliber chart range contains no daily averages (previously the
chart rendered as an unlabeled empty grid).
- Subscribe HomeLive to the "prices:updated" PubSub topic so the
cheapest-per-caliber grid refreshes without a full page reload.
- Drop the unused textColor computation and unused max series from the
chart hook/data.
LiveView's morphdom was replacing the canvas element inside the chart
container whenever filters were toggled, destroying the Chart.js
rendering context. Add phx-update="ignore" to the chart container so
LiveView preserves JS-managed children after initial render.
Replace cron-based scheduling (every 4h) with self-scheduling jobs
that randomly pick 7-12 hours between runs. Also increase the
inter-request delay from 5-15 minutes to 10-20 minutes.
Previously combined as a single "556-223" caliber. Now tracked separately
with dedicated scraper URLs per retailer. Also fixes broken URLs for
Lucky Gunner, True Shot Ammo, and Palmetto State Armory.
Add True Shot Ammo (Shopify JSON), Palmetto State Armory (Magento HTML),
Bulk Ammo (Magento HTML), and Natchez Shooters Supply (GraphQL API).
Extends scraper infrastructure with HttpClient.post_json/3 and an
optional fetch/2 callback on the Scraper behaviour for scrapers that
need custom HTTP flows (e.g. GraphQL POST requests).
