+# Site Parser Worker
+
+The worker is a stateless executor. The main application owns source configs,
+schedules, database state, and queues. Each request gives the worker a source
+URL, a versioned JSON instruction, and optional Cloudflare session state. The
+worker returns normalized items plus per-item diagnostics.
+
+## Config v1
+
+- `discovery.type`: `rss` or `html`.
+- `discovery.fields`: where list/RSS values are located.
+- `detail.enabled`: open every discovered item when enabled.
+- `detail.root_selector`: limits extraction to the actual article.
+- `detail.fields`: exact field rules. A rule may contain ordered `candidates`.
+- `detail.media`: exact selectors and fallback attributes for media.
+- `detail.transport`: `http`, `fetch`, or `browser`.
+- `access.type`: `auto`, `http`, `browser`, or `cloudflare`.
+- `retry`: bounded attempts, delay, and per-attempt timeout.
+
+Field extraction modes are `text`, `html`, `attr`, and `json`. Date rules can
+provide `formats` and `timezone`. Relative links are resolved against the page
+URL. Unknown iframe/video providers are returned as `external_video`; they do
+not fail the item.
+
+Errors are isolated to one item. Successful items are returned with
+`status=partial`; the source receives a visible diagnostic in the main app.
+Only discovery/network failure prevents the whole request from returning a
+batch.
+
+## PopularAirsoft
+
+Use `https://popularairsoft.com/` as the source URL. Its RSS mixes full news
+articles with short video pages, so the reliable discovery surface is the
+`The Latest News` HTML block. The worker opens the main page through
+Cloudflare, collects `/news/...` links, and downloads each article using the
+same clearance and an impersonated browser TLS fingerprint.
