- Route image-validation, Matrix image-download, and wayback/archive.today
fetches through safehttp so feed-controlled URLs can't reach loopback/
RFC1918/cloud-metadata IPs (incl. via redirects).
- Cap feed body size with safehttp.LimitedBody (16 MiB) to prevent OOM.
- Fail closed if matrix.pickle_key is unset/<16 chars; drop the hardcoded
"pete_pickle_key" default that silently weakened E2EE-at-rest.
- Gate !post behind a matrix.admins allowlist; empty = disabled (channel
rooms are public, so empty must not mean anyone).
- Reject /\host open-redirect bypass in post-login safeNext.
- Allowlist http(s) schemes for the Matrix link href; escape JSON embedded
in inline <script> (prefs/sources blobs).
Bypass-UA retry (Googlebot + Google referer) for soft paywalls, JSON-LD
gating scoped to Article-typed nodes, HTTP 402 treated as explicit
paywall, Wayback freshness filter (30d cap), archive.today as secondary
archive fallback, and transport failures no longer trigger snapshot
swaps. When gating is detected and no archive workaround succeeds, the
story is stored with paywalled=1 and the web card renders a diagonal
red rubber-stamp overlay so readers know the link is gated.
Fetch each new article once and measure visible <p> text. If body is below
500 chars (or fetch fails), resolve a Wayback snapshot via the
archive.org/wayback/available API and use that URL for both the og:image
fallback and the posted link. Dedup keys stay derived from the original
URL so paywalled/non-paywalled hits collide as before.
- New: internal/ingestion/article.go (FetchArticleMeta via goquery)
- New: internal/ingestion/wayback.go (ResolveWayback)
- Removed: internal/ingestion/og.go (folded into article.go)
- poller.go: dedup first, then one article fetch, then snapshot fallback
