🧭 reddit-compass

Your broad trendwatching radar. 12 stable domains, multi-source evidence, one compass.

You're writing a book about how AI is changing work. Or running a column. Or building a product and need to know what the market actually thinks — not what press releases say.

So you check Reddit. Then Hacker News. Then NYT. Then Wired. Then FT. Then TechCrunch. Then Medium. Then ProductHunt. Every. Single. Morning.

That's 45 minutes of tab-switching before your first coffee. And you still miss the thread that went viral at 2 AM — the one where 400 laid-off engineers described exactly the pain your product solves.

reddit-compass builds a versioned Radar. Broad Radar watches the world; AI-native Lens keeps book/RBC research focused on AI, work, institutions and markets. Автоматическое ночное расписание сейчас поставлено на паузу: запуски выполняются оператором вручную.

What reddit-compass does for you

Ручной режим (расписание временно отключено)

Периодические collection, finalization и Engine jobs на production-хосте отключены. До согласования нового интервала оператор вручную запускает только нужные этапы и вручную решает, публиковать ли прошедший quality gate выпуск. Таблица ниже — прежний ориентир последовательности, а не действующее расписание.

Time (UTC / MSK)	What happens	Why you care
14:00 / 17:00	RSS sections from mainstream, business and tech/culture sources	The mainstream narrative — what the masses hear tomorrow
14:10 / 17:10	Hacker News front/search snapshots	What developers are building and arguing about
14:20 / 17:20	Optional Ladder-supported publisher listings	Extra headlines/abstracts from configured publisher pages
14:30 / 17:30	ProductHunt pulse	What's launching right now
14:45 / 17:45	Snapshot finalizer creates one raw run in `compass.db`	Completion is factual and does not depend on LLM
16:00 / 19:00	Versioned Engine runs facets → stories → bounded Qwen → trends → quality → shadow	Repeat analysis without re-collecting
manual	Operator inspects and publishes a complete gated version to `broad`	Radar never silently replaces a good version with a partial one

Reddit is collected read-only from configured broad packs. If the server route is unavailable, a local residential route can produce a JSONL artifact that is safely merged on the VPS.

You wake up to a report that says:

# Read the published UI.
reddit-compass serve               # REST API + UI on :8900

fetch, hn, rss, ladder, ph, all and signals remain compatibility commands for a single adapter or legacy artifacts. They are not the production publication path: current Radar is produced by collect and the versioned Engine. db rebuild is legacy recovery only, never a normal way to iterate on stories or trends.

What it will NOT do — by design

Written into AGENTS.md. The service refuses, by architecture:

Post, vote, or comment on Reddit. (Read-only. Always.)
Bypass account bans or impersonate users. (Proxy is for rate limits only.)
Train ML models on collected content. (Explicitly forbidden.)
Expose secrets in git, logs, or API responses. (scripts/secret-scan + detect-secrets gate.)
Touch other services on the VPS. (Isolated network + volume.)

Trust is built in what a system won't do. A scraper that posts is a liability. A scraper that can't post is a tool you can leave running at 3 AM.

How it works

reddit-compass has two jobs that are intentionally separated.

public sources
  → adapter snapshots (JSONL)
  → Collector / compass.db             raw facts and source health
  → immutable Data Release
  → Trend Engine / trend_engine.db     facets → stories → trends → quality
  → RadarPublication pointer
  → News / Stories / Trends / Radar / Today, each with evidence links

Collector builds the corpus. Source adapters fetch public/read-only data from Reddit, Hacker News, RSS/Atom feeds, optional Ladder-supported publisher pages and ProductHunt. Raw materials, observations and source health go to compass.db; JSONL snapshots remain an exchange/debug format.
Engine freezes a Data Release. A finalized collection run is copied into trend_engine.db as an immutable release. Later changes in compass.db cannot move old experiments.
Facets classify items. The Engine assigns domains, themes, entities, event frames, source cluster, content scope and pain points. This is the layer that powers theme clouds and domain drill-down.
Stories group concrete events. URL canonicalization, Reddit target URLs, title/BM25 similarity, entities, temporal windows, embeddings and bounded Qwen review decide whether items describe the same event. Stories keep direct evidence links.
Trends group repeated patterns. Trend discovery runs over accepted stories, not raw posts/articles. A trend needs multiple stories over time; reposts or syndicated copies should not inflate it.
Quality gates decide publishability. Engine releases are evaluated for overmerge risk, domain balance, naming quality, evidence coverage and regression against the baseline.
Radar/Today read only publications. UI does not read arbitrary experiments by default. A manual RadarPublication pointer selects the Story/Trend release shown in broad, ai-native or shadow. Rollback switches the pointer back.

What “ready” means

State	What is guaranteed	What UI can safely show
`collection complete`	Every requested source artifact was finalized into raw facts; source health is recorded. Qwen is not required.	A new immutable input can be created; it is not yet an editorial verdict.
`Data Release finalized`	Exact rows, observations and health are copied with checksums. Later collection cannot alter the experiment.	Engine/preview diagnostics.
`analysis evaluated`	Facets, stories, trends and the quality report exist for one immutable release.	Shadow/preview only until a human publishes it.
`Radar published`	Input is complete, quality gates passed and a manual channel pointer selected the release.	`Today`, Radar and direct News/Story/Trend evidence links.
`partial` / `failed`	A missing or failed source is visible; nothing is silently called complete.	Diagnostics or `shadow`; the last good Broad publication remains live.

Sources → 6 source clusters → 12 broad domains → stories/trends → Today + Radar

Collection and analysis are separate runtimes. collect writes raw facts to compass.db; the versioned Engine freezes them into trend_engine.db. Radar reads only a manually published Story/Trend combination, so a collection failure or experimental attempt cannot erase the last verified dashboard.

Quick Start

Prerequisites

Python 3.12+, uv
Playwright: uv run playwright install chromium
(Optional) Docker for VPS deployment

Install

git clone https://github.com/eiler2005/reddit-compass.git
cd reddit-compass
uv sync

First run

# See the configured broad surface without network access:
uv run reddit-compass collect --profile broad --sources reddit,hn,rss,ladder,ph --dry-run

# Create one raw collection run. This fetches only public/read-only sources.
uv run reddit-compass collect --profile broad --sources reddit,hn,rss,ladder,ph

# Iterate on the same frozen input without collecting again.
uv run reddit-compass engine cycle --profile broad --window 7 --publish-channel shadow

# Start the API:
uv run reddit-compass serve
# → http://localhost:8900/docs (Swagger UI)

Publishing to broad is deliberately manual after the quality gate. The exact release IDs, completion rules and rollback command are in docs/COLLECTION_LIFECYCLE.md.

Optional residential proxy for Reddit

Set REDDIT_COMPASS_PROXIES in .env.secrets to the provider-issued HTTP proxy URL (see .env.example for the placeholder format). The Reddit bootstrap request and public .json listing/comment requests then use that proxy; if the HTTP client receives HTML or HTTP 403, the Playwright fallback launches Chromium through the same configured proxy. Request pacing remains 4 seconds, with at most two 429 retries separated by 10 seconds. Proxies are only for rate-limit mitigation — never for account bans, logins, posting, voting, or commenting.

For rotating residential pools set REDDIT_COMPASS_ENGINE=playwright: Reddit serves .json to full browser traffic but frequently rejects bare HTTP from pool IPs with 403 (verified 2026-07-27). If the provider offers a sticky-session endpoint (same exit IP for ~20 minutes), prefer it — per-connection IP rotation causes transient Failed to fetch errors (the browser engine retries them automatically).

Keep credentials only in .env.secrets (gitignored); do not commit or log them. An optional local proxy for other approved public read-only sources is documented only in gitignored operations notes and secret files; never move it into tracked configuration or REDDIT_COMPASS_PROXIES.

Automation (every 2 nights)

VPS collects RSS, HN, Ladder and ProductHunt, then finalizes one raw snapshot run at 14:45 UTC and runs the Engine in shadow at 16:00 UTC. Pipeline runs every 2 nights (odd days, */2 in cron) — Engine cycle on 1-CPU VPS takes 30-60 min, daily runs are redundant with a 7-day window. The exact version-controlled schedule is in deploy/hostkey/reddit-compass.cron; the completion and publication rules are in docs/COLLECTION_LIFECYCLE.md. Full stage-by-stage timing: docs/COLLECTION_LIFECYCLE.md §5.1.

Reddit can be collected separately from a local approved route and synced to the VPS as a JSONL artifact. Nightly scripts/fetch-and-sync.sh (launchd, 03:17) chooses the route from gitignored config and supports an explicit RC_PROXY_MODE=on|off override:

./scripts/fetch-and-sync.sh               # fetch + sync (route chosen automatically)
RC_PROXY_MODE=on ./scripts/fetch-and-sync.sh --fetch   # force proxy route
# manual alternative:
uv run reddit-compass fetch --stealth     # collect locally from approved route
scp data/snapshots/$(date +%F)/posts.jsonl "${RC_DEPLOY_USER:-deploy}@${RC_DEPLOY_HOST:-reddit-compass-vps}:/tmp/"
ssh "${RC_DEPLOY_USER:-deploy}@${RC_DEPLOY_HOST:-reddit-compass-vps}" \
  "docker cp /tmp/posts.jsonl rc-api:/data/snapshots/$(date +%F)/"

VPS deployment

./deploy/hostkey/deploy.sh
# Deploys: API (FastAPI) + Caddy (reverse proxy) + batch collector
# Target host and public URL come from deploy/hostkey/.env.secrets

API

OAuth2 client credentials → JWT. CORS-configured for external consumers.

# Get token:
curl -X POST http://localhost:8900/oauth/token \
  -H "Content-Type: application/json" \
  -d '{"client_id":"practicum","client_secret":"<secret>"}'

# Query posts:
curl -H "Authorization: Bearer <token>" \
  "http://localhost:8900/api/v1/posts?date=2026-07-22&subreddit=artificial&limit=10"

Endpoint	Auth	Description
`GET /health`	—	Liveness probe
`GET /dashboard`	—	HTML dashboard (editorial style)
`GET /docs`	—	Swagger UI
`POST /oauth/token`	—	Client credentials → JWT
`GET /api/v1/snapshots`	Bearer	List snapshot dates
`GET /api/v1/posts`	Bearer	Posts with filters + pagination
`GET /api/v1/signals`	Bearer	LLM-extracted signals
`GET /api/v1/stats`	Bearer	Aggregated statistics

LLM-assisted analysis

The Engine is deterministic first and LLM-assisted second. URL normalization, title/entity matching, temporal windows, embeddings and quality gates do the heavy lifting. Qwen is used for bounded grey-zone review, Russian naming/interpretation and project lenses; it does not cluster the whole corpus directly.

export DASHSCOPE_API_KEY=<qwen-api-key>
uv run reddit-compass engine cycle --profile broad --window 7 --publish-channel shadow

Engine facets and Qwen-reviewed outputs include:

Domains/themes — stable broad taxonomy plus narrower topic tags.
Pain points — problems people or institutions describe.
Evidence refs — every accepted story/trend points back to source items.
Project scores — book/RBC/business relevance can diverge by lens.
Trend interpretation — why a pattern matters after the candidate passed clustering gates.

Model pyramid (price / quality)

Task	Model	Why
Synthesis (themes, column ideas, narrative shifts)	`qwen3.8-max-preview`	Complex, few calls, off-peak discount 17:00–03:00 MSK
Classification / pair review	`qwen3.6-flash`	High-volume bounded review and extraction
Simple tasks (filtering, summarization)	`qwen3.6-flash`	Cheapest

Dashboard & Trend Radar

Published UI workspaces:

View	URL	Purpose
Today	`/today`	Утренний бриф: изменения, лента до 20 материалов и блок «Новое на Reddit» — свежие посты выпуска прямыми ссылками, с фильтрами по тематикам
News	`/news`	Сырой inbox опубликованного Data Release: материалы, источники, sections, связанный story
Stories	`/stories`	Конкретные события с evidence items; не raw news и не тренды
Trends	`/trends`	Повторяющиеся паттерны поверх нескольких stories
Pulse	`/pulse`	Reddit-native сигналы: облака тематик с примерами, percentile внутри саба, velocity, depth, gaps. Клик по тематике даёт топ-20 прямыми ссылками на посты
Radar	`/radar` → `/runs/{date}/radar`	Полный аналитический workspace: landscape, shelves, coverage, project panels
Project Lens	`/projects/rbc`, `/projects/book`	Книга/РБК/business поверх опубликованных stories/trends
Story detail	`/stories/{id}`	Evidence опубликованного Engine story
Trend detail	`/trends/{id}`	Published trend pattern, member stories and evidence
Runs	`/runs`	История запусков с реальными counts

Навигация — четыре раздела: Сегодня · Лента · Тренды · Reddit Pulse. Остальное достижимо по прямым ссылкам с карточек и из /runs.

Все страницы читают только опубликованный релиз. Если публикации нет, страница честно говорит об этом и предлагает engine cycle — параллельной проекции из сырого compass.db больше не существует. Старые адреса сохранены редиректами: /explore → /news (с переносом строки запроса), /dashboard → /today.

Versioned Story/Trend Engine

Для итераций без full rebuild используется trend_engine.db: полные frozen Data Releases, независимые Facet/Story/Trend attempts, Golden Set, Qwen-review только серой зоны и атомарные publication pointers.

Published analysis is explicitly split into News → Stories → Trends → Project Lens. See docs/NEWS_STORIES_TRENDS.md. End-to-end collection and analysis lineage is documented in docs/COLLECTOR_TO_TRENDS_FLOW.md. Published Radar includes a cockpit section that links these layers.
