For a public deployment, put the app behind an HTTPS +reverse proxy and set `-public-url https://community.example.com`. This exact +origin is used for browser request validation and secure cookies. If the proxy +connects from loopback and appends or overwrites `X-Forwarded-For`, add +`-trusted-proxies 127.0.0.1/32,::1/128`. Only configure networks actually used by +your trusted proxies. Without this flag, quotas use the direct connection IP; +client-supplied forwarded headers are ignored. Keep the app bound to loopback +when a same-host reverse proxy is used. + +The standalone community listener exposes only the app and `/api/*`. It does +not proxy arbitrary backend paths or expose backend administration. + +## Contribution delivery + +The app immediately rejects known adult domains, private/non-web URLs, and executable download links. Valid URL batches are stored for prevalidation. A background worker fetches each public webpage using restricted network egress and checks the destination, title, body text, image alt text, and metadata. It reuses Cosift’s adult-content classifier, then calls the authenticated `POST /admin/community-moderate` endpoint for a contextual safety decision. Only an explicit `allow/safe` result can be delivered to `POST /admin/community-enqueue`, which requires an active crawler with both `crawler.public_only=true` and `crawler.filter_adult=true`. An older backend or an unguarded +crawler cannot accept community submissions through this endpoint. + +Public-only crawling resolves DNS, rejects private and special-purpose +addresses, and connects to the checked IP on port 80 or 443. The same transport +covers redirects, robots, and sitemap discovery. It uses direct HTTP egress; +the in-process crawler rejects proxy/remote-fetcher configurations in this mode. +For a cluster, enable it on every receiving shard. Forwarding from a guarded +shard also uses the guarded endpoint. + +Content checks reject explicit adult material, malware/phishing, graphic violent abuse, extremist promotion, and serious illegal harm. The classifier policy distinguishes harmful promotion from neutral news, medical education, academic work, and defensive security research. Raw webpage text is treated as untrusted data, and malformed or contradictory classifier responses cannot authorize delivery. + +`pending` is shown as **Checking**; `rejected` and `unverified` remain out of the crawl queue and include a reason in contribution history. Unavailable services retry; unsupported media, login walls, insufficient text, excessive text, and inconclusive content decisions remain unverified. The page limit is 2 MB, with at most 32,000 bytes of readable text and 4,000 bytes of metadata for contextual classification. + +These are automated URL/text safety checks, not a guarantee or an antivirus scan. Images and video are not visually classified; image-only pages cannot pass based on empty text. A site can also change after validation. The crawler independently checks adult content again before indexing. + +Delivery uses the submitted frontier lane. Failed delivery remains `pending` +with exponential retry delay, capped at roughly 43 minutes. Successful delivery +becomes `queued`. A restart resumes pending work. A crash after enqueue can +cause a duplicate delivery; frontier insertion is idempotent. + +**Queued means delivered to the crawl queue, not indexed.** Existing robots, +domain allow/exclude rules, fetch failures, and crawler policy still apply. +The portal does not silently expand an operator's domain allowlist. Keep those +rules aligned with the public sources you intend to accept. + +## CLI and CSV + +Guest contribution (no account or token needed): + +```sh +./cosift contribute -server https://community.example.com -guest \ + https://go.dev/doc/ https://www.rust-lang.org/learn + +./cosift contribute -server https://community.example.com -guest -csv sources.csv +``` + +For member submissions, create an account in the web app and set `COSIFT_EMAIL` +and `COSIFT_PASSWORD` in your shell environment. Keep the password out of command +arguments and shell history. Omit `-guest`: + +```sh +./cosift contribute -server https://community.example.com -csv sources.csv +``` + +Without either credential, the CLI defaults to guest access. `-guest` explicitly +ignores configured credentials. `-email` overrides `COSIFT_EMAIL`; `-csv -` reads +stdin. Flags precede positional URLs. The CLI logs out its temporary session +after an authenticated submission. + +CSV accepts a single headerless URL column, or a column called `url`, `urls`, +`webpage`, or `website`. Other columns are ignored when a recognized header is +present. Quoted fields, commas in titles, and UTF-8 BOMs are supported: + +```csv +title,url +Go documentation,https://go.dev/doc/ +"Rust, getting started",https://www.rust-lang.org/learn +``` + +Limits: 100 rows/URLs per request, 1 MB request body, 2,048 characters per URL. +Duplicate URLs are normalized and collapsed; members also receive a duplicate +count for URLs they previously contributed.

Guest allowance records use a salted IP hash, not a raw IP; expired +records are removed as allowances are reserved.

Their synchronous backend timeout is three minutes; configure reverse proxies to allow at least four minutes.
