The plugin host's half of the plugin speed work. The app's half is MODSetter/SurfSense#2260. Each can ship without the other.

Why

Users said the scraper plugins were very slow. Every tool was profiled live before any change. Most of the time was waiting, not work:

  • Indeed warmed up on the home page every call and solved Cloudflare every time (20-125 s).
  • Google Search sat 5 s in a network-idle wait on every page and rendered queries one after another.
  • TikTok opened a browser for comments and trending that its own JSON API answers in about 1 s.
  • Web Crawl spent 17-25 s running trafilatura over a 7 MB page, and returned 1.8 MB replies.
  • Amazon sent a fake Google referer that got most search pages blocked: 0 products in 3 of 3 baseline runs.
  • Every HTTP plugin inherited Scrapling's 30 s timeout with 3 hidden retries on the same dead exit, which caused the 30-90 s tails.

Also, the agent never saw the data: opencode keeps only a tool result's text when it has any, and every plugin's text was a titles-only summary. Prices, page text, reviews and People Also Ask answers only reached the agent through follow-up calls.

What changes

A shared layer (plugins/remote/proprietary/scraping, mcp_server, host), one commit each:

  • http.py: one attempt per request with a split connect/read timeout, raw bytes, and a perf line per request. sessions.py: keep-alive holders that rotate or burn their exit, and leased sticky exits. concurrency.py: an ordered, bounded fan-out, and a hedged second attempt on a fresh exit.
  • browser_pool.py and settle.py: one browser pool for every plugin, with capped browsers, pages and kept contexts. It waits for DOMContentLoaded or a ready selector, and solves Cloudflare only when a challenge is on the page.
  • On the host:
    • plugin lifespans (warm-ups at startup);
    • one license cache per process, stale-while-revalidate;
    • kept API clients (the captcha solver now polls every second);
    • tool_result: each item as a compact JSON line in the text, capped at 32 KB, so the agent reads the data;
    • stage progress;
    • 405 on GET and DELETE of the stateless MCP endpoints.
  • Scrapling is pinned to 0.4.15 (the pool uses its private API, with a contract test), and curl_cffi and orjson are declared.

Per plugin, one commit each, with speed changes, data-bug fixes and kill switches. Each commit message lists them.

Results

OLD is release 622c1de; NEW is this branch. Both ran on the same machine and proxy, alternating call by call where both were re-run. Times are seconds per tool call, p50 (n is small: 1 cold and 2 warm on NEW). Residential exits are noisy, so differences under about 1 s are noise. The full tables are in the first comment.

Plugin Call OLD cold → NEW cold OLD warm → NEW warm
Google Search 1 query 22.5 → 18.7 (both paid a captcha) 15.7 → 6.0
2 queries 37.9 → 24.8 36.1 → 10.2
Indeed search, 3 jobs 19.7 → 4.0 76.6 → 2.3
search + 2 details 45.2 → 11.1 40.5 → 1.8
YouTube video with subtitles 12.8 → 1.3 13.4 → 0.9
comments, newest 4 5.2 → 2.7 7.6 → 2.0
Google Maps reviews, 2 places × 5 17.2 → 6.1 (3.7 after review fixes) 10.7 → 2.2
reviews, name-only URL 10.9 → 2.3 12.6 → 3.8
Amazon search, 10, no details 12.5 → 2.3 (OLD: 0 products) 58.1 → 2.2
defaults (10 with details) 68.5 → 10.6 (OLD: null prices) 31.6 → 7.7
product + offers + sellers 29.0 → 4.5 16.3 → 5.9
Walmart 200 reviews 69.6 → 9.7 33.7 → 11.1
3 product URLs 10.1 → 4.4 8.0 → 4.4
TikTok comments 40.4 → 1.8 59.3 → 6.4 (3.7 after review fixes)
trending 8.1 → 1.8 7.1 → 2.2
user search 31.9 → 10.9 (OLD failed 2 of 4) 28.5 → 5.6
Web Crawl docs, depth 1, 3 pages 28.5 → 4.2, 1.85 MB → 49 KB 25.5 → 8.0
requests docs, 10 pages 29.0 → 6.2 18.3 → 8.3
a 404 7.0 → 1.6, now failed instead of success 6.0 → 1.0
Reddit give-up on a closed endpoint 156 → 16-50, then 0.005 while latched

Where NEW is slower or no better (all explained in the comment):

  • Google Search with site: (warm 7.5 → 12.2): Google ignores site: on most renders. NEW now drops the off-site results, re-renders once, then tries SearXNG. OLD returned 9 off-site results as if filtered.
  • YouTube comments, top 15 (cold 3.9 → 5.9): NEW reads the second reply page that OLD never reached (a data fix).
  • Web Crawl example.com cold (1.7 → 3.7): one sample met a dead exit, a 5 s connect timeout and a retry.
  • Google Search People Also Ask: NEW returns 4-9 questions (all clicked ones answered) against OLD's 9-12. A trial at GOOGLE_SEARCH_PAA_STABLE_MS=800 / _PAA_GRACE_MS=3000 reached parity, but a warm render then took 15 s. Speed or PAA completeness is your call; both values are env settings.

Data parity: item counts match OLD or beat it on every input, and the fields that changed are the ones the data-bug fixes target. Each plugin has a parity.md; they are summarized in the comment.

Tests

  • New offline tests for every change: local socket servers for timeouts and hedging (a blackhole proxy), fakes for the pool's caps, TTLs and cancellation, and fixture-based tests for each data-bug fix from real captures (scrubbed).
  • Local, as CI runs it: uv run pytest from plugins/remote/host (1428 passed, 25 skipped), ruff check .. and ruff format --check .. clean, after merging dev.
  • Every plugin went through an adversarial review. The YouTube fix step stalled before it reported. Its two must-fix items are in the code with tests, and its package passes, but no reviewer re-checked that fix.
  • An all-plugin smoke on one host passed: one call per tool, every reply under 32 KB with the data in the text, /health 200, GET 405, no orphan processes. So did a soak of 16 browser-plugin calls: host RSS 220 MB, the whole tree 1.6 GB with Chromium, and no orphans.

Before deploying

  • TikTok on Linux: profile, hashtag and search listings now run in the shared pool with the headful launch profile, under Xvfb in the container. Only Windows headless was measured. Run one profile scrape in the container first.
  • Browser cap: Indeed, TikTok (headless, and headful in prod) and Web Crawl's dynamic tier share the pool. Depending on the stealth config that is 3-4 distinct launch profiles, against SCRAPING_MAX_BROWSERS=3, so a fourth evicts the least recently used idle browser. That costs a relaunch, not an error. Google Search still keeps its own browser outside the pool (moving it, GS-6, is not done). A browser is about 300-350 MB: check the container's memory limit before raising the cap to 4.
  • REDIS_URL: set it on the plugin host so Google Search shares solved IPs across restarts. Without it, the first calls after a deploy pay captcha solves.
  • SSE through Coolify: progress only helps if text/event-stream passes uncompressed. Check one call with curl -N --compressed before changing labels.
  • Rollback without a deploy: every risky change has an env switch, read at startup. SCRAPING_HEDGE=0 and SCRAPING_MAX_IDLE_SESSIONS=0 turn off hedging and cross-call reuse everywhere. The full list, with defaults, is in plugins/remote/host/.env.example and in the second comment.
  • Block-rate gates for the request-shape changes ran at 10-30 fetches per arm, not the planned 30+, and no change raised blocks in them. Two changes failed or were not gated, and stay off: WALMART_CANONICAL_URL failed its gate, and cross-call session reuse (YOUTUBE_KEEP_IDLE, GOOGLE_MAPS_KEEP_IDLE) is opt-in. For 48 h after deploy, watch the hosts' [perf] lines (blocked=1, hedge=).

Not in this PR

  • A static JS/CSS cache for Google and TikTok (the next win for warm listing pages).
  • Google's organic-only mode.
  • Indeed's 20-minute soak.
  • New data paths for Reddit and Instagram profiles.
  • A job runner for very large calls.

The deferred list with reasons is in the second comment.

Summary by CodeRabbit

  • New Features
    • Scraping tools now provide clearer progress updates and compact, structured results, with oversized text safely shortened.
    • Web crawling supports per-page link limits and reports when links or contact details are truncated.
    • Google Search supports improved locale defaults and site-specific filtering; YouTube can retrieve native subtitles and combine URL and search inputs.
    • Product, job, social media, video, and review scrapers return richer details, including pricing, ratings, translations, captions, and media information.
  • Bug Fixes
    • Improved handling of blocked or incomplete pages, redirects, duplicate results, and partial failures across supported services.
    • Corrected parsing of dates, counts, links, verification badges, and other captured details.

… ordered fan-out

Shared by the scraper plugins:

- scraping/http.py: one attempt per request with a split (connect, read)
  timeout, no hidden Scrapling retries or sleeps on the same exit, raw bytes
  back (no lxml round trip on the event loop), and one perf line per request.
  FAIL_FAST gives the same timeouts to call sites still on Scrapling.
- scraping/sessions.py: a per-job keep-alive SessionHolder that rotates or
  burns its exit on a block, sticky exits leased so no two jobs share one,
  and an optional, capped pool of idle sessions kept across calls.
- scraping/concurrency.py: ordered_map, a bounded fan-out that yields in
  input order and cancels what is left when the caller stops, and hedged,
  a second attempt on a fresh exit when the first is slow.

curl_cffi and orjson, already installed through Scrapling, are declared, and
Scrapling is pinned to 0.4.15, whose private browser API the pool uses.
scraping/browser_pool.py generalises Google Search's kept browser: at most 3
browsers on the browser loop, a fresh proxied context per page, a capped set
of kept contexts (for Indeed's Cloudflare clearance) with a TTL, and close or
relaunch on a crashed browser without taking sibling pages down. Cancelling a
call closes only its page.

scraping/settle.py navigates to DOMContentLoaded or a ready selector with a
bounded idle wait, and solves Cloudflare only when a challenge is on the page.
A contract test fails if Scrapling's private helpers move.
…he agent reads

- A plugin's server.py may expose a lifespan: the host enters it at startup,
  warm-ups run in the background, and scraping/lifecycle.py closes the shared
  sessions, browsers and API clients once at shutdown.
- One license cache per process, stale-while-revalidate, instead of one per
  plugin: the app's 5-minute check no longer pays a Keygen round trip per
  plugin. Refusals and the 24 h grace work as before.
- Kept API clients for Keygen, SearXNG and the captcha solver, which now polls
  every second.
- mcp_server/results.py: tool_result puts each item in the text as one
  compact JSON line, within 32 KB. opencode reads only a result's text when
  there is any, so the agent never saw prices, page text or reviews. A request
  with x-surfsense-text-only: 1 gets no structured copy.
- mcp_server/progress.py: stage progress, so a long call never sits silent.
- GET and DELETE on /<id>/mcp answer 405: the stateless host has no stream to
  offer, and each GET held an idle SSE connection open per plugin.
…nd fix its results

- No network-idle wait or fixed sleeps: the page is read once results are on
  it, and People also ask and the AI Overview expand on events.
- A call's queries and pages render concurrently, in order; /goto links
  resolve during the render on one session per wave, fail fast and hedge.
- The browser launches at startup; the DOM is trimmed before it is read.
- Fixes: resultsTotal on page 2 and in ja/zh, dates ending in a dash, star
  ratings read as dates, 'Read more' in descriptions, AI Overview sources
  (parsed and resolved), displayedUrl on forum cards, countryCode stamped as
  sent, site: results that Google ignored (dropped, re-rendered, then SearXNG),
  and PAA answers after a captcha.
- The agent reads each page's results, PAA and AI Overview in the text.

Warm, one query went from about 16 s to 6 s, two queries from 36 s to 10 s.
GOOGLE_SEARCH_FAST_SETTLE=0 restores the old waits.
…tails as JSON

- No per-call home-page warm-up: go straight to the page and solve Cloudflare
  only when a challenge is there.
- One kept, country-pinned browser context holds the clearance across calls,
  so a warm call is about 2 s instead of 30-125 s.
- Job details come in batches from Indeed's own spa=1 JSON inside the page;
  a call's targets run concurrently; the inline JSON is read with raw_decode.
- Fixes: jobKey on direct /viewjob URLs, detail salaries, company rating,
  review count, job types and country on details, clean companyUrl, 0 ratings
  read as unknown, cross-target dedupe, a 403 page no longer read as empty,
  and a failed warm-up no longer recorded as done.

INDEED_KEPT_CONTEXT=0, INDEED_SPA_DETAILS=0 and INDEED_TARGET_CONCURRENCY=1
turn the new paths off.
…xits, exact counts

- Fail fast and rotate on Google's sorry redirect instead of following it;
  hedge slow requests onto a second exit (1 rotation per refused exit).
- Subtitles from YouTube's own player on the warm session, alongside the
  watch fetch and across videos: a video with subtitles went from 13 s to 1 s.
- Channel tabs fetched together without the redundant sort chip; the
  playlist stops at its limit; comments read reply pages and use /next.
- JSON read with raw_decode and orjson, one parse per page.
- Fixes: search terms dropped next to urls, truncated search text, rounded
  views and likes, SEO keywords as hashtags, duration formats, verified
  badges, reply pagination, None counts, a translation request without
  subtitles, and relative times.
- The agent reads every video in the text; transcripts share the cap.

YOUTUBE_KEEP_IDLE=1 keeps warm sessions across calls (off by default).
…and fix review text

- Fail-fast transport with one keep-alive session per place job, rotated on a
  block and hedged when slow; no Chromium fallback on a 403 or 429.
- The place header is fetched with the first reviews page; sources and places
  run concurrently; no NID cookie mint; name-only URLs resolve with one search
  RPC; place_id to fid is cached.
- Fixes: textTranslated was the truncated preview, raw <br> and entities in
  reviews and replies, '' for rating-only reviews, the address repeating the
  name, phoneUnformatted, kgmid on reviews, @lat,lng URLs resolving to the
  wrong place, and a refused request silently returning nothing (it now
  rotates, then names the input in an error item).

Reviews for 2 places went from about 11-22 s to 2-6 s. GOOGLE_MAPS_KEEP_IDLE=1
keeps warm sessions across calls (off by default).
…on fallback pages

- Fail-fast transport with one hedge on slow fetches; sources run together
  in order; the offers panel runs alongside the product page and sellers as
  soon as they are known; one detail wave for the default call.
- No Google referer on search, best-seller and offers requests: in an A/B it
  cut blocked search pages from 10 of 10 to 3 of 10.
- Sponsored cards are unwrapped instead of failing as product_not_found, and
  max_items fills from the current page before paginating.
- Fixes: listPrice read the per-unit price, search positions and
  reviewsCount ('89.7K' read as 897), isAmazonChoice/isBestSeller always true,
  duplicate ASINs, null prices, stock and delivery on Amazon's fallback product
  page (about 70% of pages), offer prices, the reviews link, and zip_code
  silently ignored (now reported, and failures cached).

A default 10-product search went from 31-74 s, with null prices, to 8-11 s.
AMAZON_NO_GOOGLE_REFERER=0 and AMAZON_HEDGE=0 restore the old behaviour.
… for variants

- Review pages after the first are fetched in parallel and deduplicated;
  start URLs and search terms run together, in order.
- Fail-fast transport with hedging; 444, 403, 5xx and a /blocked redirect are
  blocks that rotate, not pages; raw bytes and orjson instead of the lxml
  round trip.
- A failed detail returns the listing card with detailsError instead of an
  error item and an extra listing fetch.
- Fixes: variant products with 0 stars and 0 reviews, the sponsored flag and
  search provenance lost on details, duplicate reviews at page boundaries,
  reviews of other variants unlabelled, specifications and fulfillment always
  null, and lone surrogates in review text.

200 reviews went from 34-99 s to about 10-13 s. WALMART_PARALLEL=0 restores
sequential fetches; WALMART_CANONICAL_URL=1 (off) skips the /ip redirect.
…on the shared browser pool

- Comments and trending read TikTok's unsigned JSON endpoints, with the
  browser as fallback: comments went from 25-96 s to about 2 s.
- Listings run on the shared browser pool, with event-driven waits, a JS
  click, no home-page warm-up, media blocked, a hedged second country, and
  concurrent targets; profile and video pages go over HTTP.
- Geo-blocked and login-bounced exits end the attempt at once.
- user_search recovers an empty first body inside the page instead of
  starting a new browser, which made it intermittent.
- Fixes: textLanguage, isAd, isPinned, isSlideshow, mentions and slideshow
  media dropped by parse_video, business accounts marked verified, withheld
  comment pages, and the profile item counting toward max_items.
…tion, bound the output

- Pages are crawled level by level, several at once, with an exact page budget.
- HTML is capped at 1 MB before trafilatura and parsed once: a 7.3 MB page
  took 17-25 s to extract, now about 1.5 s. Extractors warm up at startup.
- The tier ladder follows the HTTP status and challenge markers: a 404 fails
  in about 1 s instead of trying the browser tiers. The dynamic tier runs on
  the shared browser pool with a bounded settle.
- Output is bounded: links and contacts are capped with totals, and every
  page gets its share of the agent's text. A 3-page crawl reply went from
  1.85 MB to 49 KB.
- Fixes: GitHub and GitLab URLs filed as social, 404s and Cloudflare pages
  returned as success, loadedUrl ignoring redirects, links resolved against
  the pre-redirect URL, the oldest date on the page used as its date,
  permalink anchors in titles, and raw HTML from the stealth tier.

A 3-page docs crawl went from about 28 s to 4-8 s.
Reddit refuses logged-out .json and Instagram's profiles sit behind a login.
Reddit now gives up after one rotation instead of about 2m50s and latches the
refusal, so calls answer at once with an error naming the countries tried.
Instagram no longer rotates on its require_login 401 and points to /p/ and
/reel/ URLs, which still work. Both use the shared license cache, progress and
text results.

Measurements in full (1 of 2). OLD = release 622c1de, NEW = this branch; see the PR description for the method.

MCP scraper plugins: speed and data fixes

This PR changes the ten first-party scraper plugins (google-search, indeed, youtube, google-maps, amazon, walmart, tiktok, web-crawl, reddit, instagram) and the shared scraping layer under plugins/remote/proprietary/scraping, plugins/remote/mcp_server and plugins/remote/host. The shared layer, as shipped:

  • SW-1 scraping/http.py: a fail-fast proxied transport on curl_cffi (tight timeouts, one attempt, raw bytes, one perf line per request); Scrapling call sites use the FAIL_FAST options.
  • SW-2 scraping/sessions.py: a per-job keep-alive SessionHolder with rotate/burn (rotate(seen=) is opt-in) and unique sticky-exit leasing; idle sessions can be kept across calls by plugins that opt in.
  • SW-3 scraping/concurrency.py: ordered_map (bounded fan-out that yields in input order and cancels pending jobs) and hedged (first-wins second attempt).
  • SW-4 scraping/browser_pool.py and settle.py: one browser pool on the browser loop (browser, page and kept-context caps), bounded settle and Cloudflare solving only when a challenge is detected. scrapling is pinned to 0.4.15 because the pool uses its private API.
  • SW-5 route-level cache for static JS/CSS: not shipped (deferred; GS-9 and TT-9 depend on it).
  • SW-6 host lifespan hooks: the host enters each plugin's lifespan(); scraping/lifecycle.py closes sessions, browsers and API clients once at shutdown.
  • SW-7 one license cache per process (shared_access(), stale-while-revalidate) and kept API clients (scraping/api_clients.py), including the captcha solver client.
  • SW-8 mcp_server/results.py tool_result (summary plus one projected JSON line per item, capped at 32 KB, structured_content unless the request sends x-surfsense-text-only: 1) and mcp_server/progress.py stage progress. The calls-in-flight progress record (app item A-9) is not done.
  • SW-9 host/post_only.py: GET and DELETE on /<id>/mcp answer 405 with Allow: POST.

How it was measured. Two arms: OLD is a detached worktree at release commit 622c1de, NEW is the implementation branch. Each arm ran on its own host started with dev_host.py, and calls alternated OLD/NEW where both were run. Cold is the first call of a tool after a fresh host start; warm is the same call repeated within 60 s. Times are curl time_total in seconds. The protocol asked for 3 + 3 calls per tool per arm (5 + 5 for HTTP tools); what ran was NEW 1 cold + 2 warm per input, OLD re-run interleaved with NEW for a subset of inputs, and stage A's OLD runs (1 cold + 1-2 warm) for the rest. Block-rate gates ran in process, interleaved, mostly at 10-14 fetches per arm (google-maps at 30). p50 is the median; with n=2 it is the mean of the two runs. "OLD, A+B" pools stage A and the re-run; the re-run row is shown separately where one exists.

Noise. Every request goes out through a residential proxy exit drawn per call or per job, and exit quality varies: slow TLS handshakes, dead exits that cost a full connect timeout, handshake failures on roughly 10-15% of new connections (amazon notes), Google /sorry captchas, Cloudflare challenges. With n=1 cold and n=2 warm, one bad exit moves a p50 or sets a max, and many differences of under about 1 s are inside that noise. A local DNS outage around 03:36-03:39 failed every request on both arms; those runs were discarded and re-run (walmart, google-maps). The verdicts below judge cold on the cold run and warm on the warm p50, and say when the max or a single run decides it.

Results per plugin

The "Blocks" column is each plugin's own blocked-attempt count from its run files (google-search: /sorry solves and walled renders; amazon: blocked fetches including 503s; tiktok: block-signal log lines; web-crawl: host-log lines with 403/429/503, blocked=1, cloudflare or captcha). "Items per run" lists every run of that row in file order; "x3" means three runs with the same count.

OLD for rust and two includes the interleaved stage-B re-runs. The stage-B OLD rust call ran on a fresh host (parity.md) but old.json flags it cold: false; it is counted as cold here, as summary_b.json does. Four later NEW rust calls from the fix stage ran trial PAA settings that did not ship and are left out.

  • rust. Cold target ≤25 s when /sorry needs a solve: met (18.7 s with a solve). The ≤11 s no-/sorry case was not measured: every cold call on both arms hit /sorry. Warm ≤8 s p50 with no run over 12 s: met (6.00 / 7.41).
  • two. Cold ≤14 s: missed (24.8 s). Both queries vetted fresh IPs at once and each paid a /sorry solve; the rule that renders the first page alone on a cold pool went in after these runs and is offline-tested only. Warm ≤10 s: missed by 0.2 s (10.2), bound by the slower 'best running shoes' render plus its expansion.
  • site. Cold ≤12 s, warm ≤9 s, on-site results only: missed (24.7 s cold with 0 results; warm 12.2 / 14.9). Google ignored site: on 4 of the 5 NEW renders, none after a captcha; each costs a re-render plus a SearXNG call, which found nothing. OLD cold returned 9 results, all off-site (the bug); NEW never returns off-site results.
  • include_people_also_ask=false (≤7 s cold, ≤4 s warm): not measured; GS-6 is not implemented.
  • pages2, nolocale: no plan target; NEW is faster on both (table).
  • Parity (parity.md): item counts match on every call; organic counts and hosts match within Google's variance. Only targeted fields differ: displayedUrl fill 0.56-0.89 to 1.00, AI Overview sources 0 to 3-18 per page, page-2 resultsTotal 2 to 123, nolocale languageCode None to "en". Open: PAA. NEW answers the 4 clicked questions; OLD warm answered 6-12 of 9-12. A two-call trial at 800/3000 ms reached parity but took the warm render to 15.2 s, so 400/1500 stayed. AI Overview text on rust was short in stage B (0, 680, 1215 chars); after the settle fix 4 NEW rust calls gave 2035-2728 chars.
  • Blocks: NEW 3 /sorry solves in 15 calls, 0 walled renders; 270 /goto links, 0 blocked, 97% resolved during the render.

OLD for c1, c3 and c6 includes the interleaved stage-B re-runs; c4, d5 and m2 have stage A only (n=1 each).

  • c1. Cold ≤6 s (≤15 s if challenged): met (4.03). Warm ≤2.5 s: met at p50 (2.28); max 2.63, 0.13 s over, on a run with no challenge.
  • c3. Cold ≤8 s: missed (11.1; the first page met a managed Cloudflare challenge, solved in 7.2 s in the browser). Warm ≤3 s: met (1.80 / 1.86).
  • c4. Cold ≤8 s: missed (9.59; a 7.2 s challenge on /cmp, and the direct job's spa=1 got a 403 on the cold context, which the landing gate now skips). Warm ≤3 s: met (1.10 / 1.16).
  • d5. Cold ≤8 s, warm ≤3.5 s for 5 details: met (3.81; 2.17 / 2.18). The OLD cold call returned 0 items (a silent 403).
  • c6. Cold ≤8 s: missed once before the landing gate (42.0 s: a /viewjob challenge not solved within the 40 s attempt cap, then burned and rotated), met after it (4.15, n=1). Warm ≤3 s: met (1.78 / 1.89).
  • m2 (no target): cold 24.8 s before the gate (2 concurrent solves of 21 and 23 s) and 29.4 s after it (1 solve of 24.4 s); warm 1.86 / 2.03 against OLD 18.5.
  • All calls: OLD cold p50 21.4 / max 85.3 (n=9), warm 50.4 / 267.0 (n=9); NEW cold 10.3 / 42.0 (n=8), warm 1.88 / 2.63 (n=12). Every miss is a cold first page that met a managed challenge (7-24 s solves).
  • Post-fix checks (not plan inputs, n=1): 2 queries with details, 25 items, 27.6 s cold and 6.12 s warm; 3 queries, 60 detailed items, 16.0 s warm; one /viewjob, 1.09 s warm.
  • Parity (parity.md): 0 unexpected value differences on shared jobKeys. Item counts identical (3/2/4/5/4/6) except OLD d5 cold (0). Fill-rate changes are targeted fields (jobKey, salary, rating, review count, jobTypes, country, companyUrl, isRemote/remoteType) or listing drift.
  • Blocks: NEW 1 of the 20 calls in new.json (c6 cold: a timeout and a rotation, recovered); OLD 3 of 18 (d5 cold two 403s; c1 and c6 re-run warm, a timeout and a rotation each).

OLD for S2, S3 and C1 includes the interleaved stage-B re-runs; the other inputs use stage A's OLD runs. YT-9 (cross-call warm sessions) was on during these runs; it has since been made opt-in (YOUTUBE_KEEP_IDLE=1), so warm calls in prod pay the 0.5-1.4 s connection open these rows skipped.

  • S2, 1 video. Cold ≤2.5 s p50: met (2.05); the ≤5 s p95 cannot be computed at n=1. Warm ≤1.5 s with YT-9: missed (1.73, the mean of 1.07 and 2.39; the 2.39 s call had a 349 ms TTFB on a kept connection, then 2.0 s to move 176 KB over a slow exit).
  • S3, video with subtitles. Cold ≤3 s, warm ≤2.5 s: met (1.29; 0.85 / 0.91), against OLD re-run 13.6 cold and 16.0 / 19.2 warm with 3 transcript blocks.
  • S4, search. Cold ≤1.5 s: missed (2.25; OLD's cold was 2.23; a cold POST is about 0.44 s TLS plus 1.55 s server TTFB). Warm ≤1.5 s: met at p50 (1.42); ≤0.9 s with YT-9: missed (server TTFB 0.77-1.14 s).
  • S5, channel. Cold ≤2.5 s, warm ≤2.3 s: met (1.96; 1.05 / 1.07).
  • S6, playlist. Cold ≤3 s: missed (5.64; one sorry block, a rotation and 3 hedges). Warm ≤2.5 s: missed (3.04 / 3.29; one watch page per call took 2.3-2.8 s on a kept but slow exit).
  • C1, comments TOP 5. Cold ≤2 s: missed (3.25; the seed /next on a new connection took 1.84 s, then 2 sequential /next calls). Warm ≤2 s (≤1.6 s with YT-9): missed narrowly (2.05 / 2.09; 3 requests instead of OLD's 7, nearly all server TTFB).
  • C2, comments NEWEST 4. Cold ≤3.5 s, warm ≤3 s: met (2.73; 2.04 / 2.21).
  • C3, comments TOP 15. Cold ≤3 s, warm ≤2.5 s: missed (5.94; 4.54 / 4.57), and slower than OLD stage A cold (3.87). NEW makes 4 sequential /next calls because the YT-5 fix now reads the second reply page; OLD stopped after reply page 1 and padded with comments 2-3.
  • Search with subtitles, 3 results (≤5 s cold, ≤4.5 s warm): not measured in the A/B.
  • Parity (parity.md): item counts match on every input and call. The 10 differences parity.py tagged UNEXPECTED were checked by hand; none is a regression (ranking drift, OLD's empty playlist item, isMonetized flicker on both arms, C2 comments empty in YouTube's payload, C3's extra replies from YT-5). S3 subtitles were byte-identical across all 6 calls.
  • Blocks: NEW 1 blocked attempt in 24 calls (S6 cold); OLD 10 over 28 calls, including blocks in all 3 OLD re-run S3 calls.

OLD for s5, r3 and r4 includes the interleaved re-runs; s1, s3 and r2 compare against stage A's OLD runs only, not interleaved, so read small differences there as noise. GMP-10 (GOOGLE_MAPS_KEEP_IDLE=1) is off by default; its row is for reference.

  • s1. Cold ≤2 s: met (1.77). Warm ≤2 s: missed (3.31, the mean of 2.00 and 4.63; in the 4.63 s call the primary hung and the hedge won). ≤1.2 s needs GMP-10.
  • s3. Cold ≤2 s: met (1.74). Warm ≤1.5 s: missed (2.69; 1.74 and 3.64): a new connection per call and slow exits.
  • s5. Cold ≤3 s: met (2.63). Warm ≤2.5 s: missed by default (3.44; the search RPC alone took 2.1-2.5 s on a fresh TLS each call); met with GMP-10 on (1.22 / 1.25).
  • r2. Cold ≤3 s: met (2.25). Warm ≤2.5 s: missed (3.77; the search RPC took 1.7-2.8 s on a fresh exit each call).
  • r3. Cold ≤4 s p50: missed in the A/B (6.12; one 403 on the reviews RPC cost a rotation), met in one post-fix run (3.74, n=1). Warm ≤3 s: met (2.23 / 2.57).
  • r4. Cold ≤4.5 s: missed (8.80; the place_id page took 3.45 s on a slow exit, then three cursor-paged review pages of 1.66-1.96 s each); one post-fix run took 4.76 s (n=1, 0.26 s over). Warm ≤4 s: met (3.87, n=1).
  • s4 (2 place_ids) and r1/r5 (1 place_id, 5 newest): not measured (not in inputs.json).
  • Parity (parity.md): same item counts and ids as OLD on every input (5/1/5/3/10/150), no NEW error items. Field differences are the data-bug fields or drift that OLD shows between its own calls (s5's 5th search result, r4's reviewContext by exit locale, owner replies 135 to 137 overnight).
  • Blocks: NEW had 2 x 403 on the reviews RPC (r3 cold; the KEEP_IDLE s3 cold), both recovered by rotation; OLD had none. Over responses: NEW 2/82 against OLD 0/119 in the live calls.

OLD for c2, c3 and c4 includes the interleaved stage-B re-runs; c1, c5 and c6 use stage A's OLD runs.

  • c1. ≤3 s: met (2.31; 2.22 / 2.97). OLD returned 0 products in all 3 runs.
  • c2. ≤6 s, 3 products, 0 sponsored errors: time missed (10.8 cold; 7.15 / 7.16 warm); products and errors met (3 products, 0 errors, 0 null prices every run; OLD returned 0 products in 3 of 5 runs). The search's first attempts are often captcha 200s (2-3 attempts at 0.3-2 s, each on a new TLS handshake), and a dead PDP exit costs the full 4 s connect timeout.
  • c3. ≤5 s p50: cold met (4.46), warm missed (5.92 / 8.52; in the 8.52 s run the offers panel was blocked 5 times plus one connect timeout). Price filled in 2 of 3 NEW runs against 0 of 6 OLD.
  • c4. p50 ≤12 s, p90 ≤20 s, 10 products, prices filled: met on everything measurable (3 NEW runs 4.36-11.1 s, one post-fix run 8.63 s; 10 products, 0 errors, 0 null prices in each). p90 cannot be computed at n=3; the max is 11.1 s.
  • c5. ≤4 s, zip applied or reported: cold missed by 0.3 s (4.30; 3 blocked home-page attempts took about 2.4 s); warm met (1.76 / 1.86, because the failure is cached); one post-fix warm run took 4.61 s. The zip was reported as not applied on every call (the home page answered 202 on every exit tried).
  • c6. ≤1.5 s, 10 distinct ASINs: time missed by 0.1-0.4 s (1.60; 1.83 / 1.91; one 1.4 MB fetch on a new TLS handshake); 10 distinct ASINs with prices met (OLD: 4 distinct, all prices null).
  • Parity (parity.md): item counts equal or better on every input. Every fill rate that moved by more than 0.2 is a targeted field, except condition on c2 (0.67 to 0): OLD filled it only from a used-offer accordion on full PDPs, as a 1,500-character buy-box blob; no stage-B change touches that parser. c5 reviewsCount 897 to 89703 is the fix.
  • Blocks: NEW 18 blocked attempts in 18 calls; OLD 132 in 24 calls.

OLD for search_details, three_urls and reviews_200 includes the interleaved stage-B re-runs. Stage A's OLD rows include the 3 time-matched OLD calls from the stage-A WM-2 block check.

  • search_details. ≤6 s: missed (10.2 cold; 6.96 / 7.45 warm). The floor is the listing render (3.4-3.8 s) plus the slowest detail (301 hop 0.75-2.2 s, page 1.3-2.4 s); WM-2 would remove the hop but is off.
  • three_urls. ≤3.5 s: missed (4.35 cold; 4.35 / 5.86 warm, one 444 retried); met on one warm run (2.85). About 2x faster than OLD.
  • search_listing. ≈4 s: warm met (3.69 / 3.73); cold missed once (23.8 s: an SSL handshake failure, a body trickling to the 16 s cap, and a hedge that hit a dead exit). measurements_b scores this input as met at p50 over all runs.
  • reviews_200. ≤9 s: missed (9.70 cold; 11.1 / 12.7 warm; one post-fix cold run 11.5 s). 200 of 200 unique reviews every run; 21-22 pages in 2 batches, with 2 pages per run hitting a dead gateway connect that the 3.5 s hedge won.
  • reviews_url_20. ≤2.5 s: cold met (2.19); warm met on 1 of 2 (1.70; the 6.42 s run needed a second dedupe batch and a hedge). measurements_b scores it met at p50 over all runs.
  • Parity (parity.md): item counts match, except OLD's three_urls cold (2 items + 1 error, a 444) and one OLD reviews_200 run (60 reviews after a 520). NEW returned 200/200 and 20/20 unique reviews; OLD 194-198 and 19. Fill-rate changes are targeted fields; the 0.89 fill on three_urls price/currency/seller is one NEW reply where the exit's store showed the variant out of stock.
  • Blocks: NEW 3 blocked requests in 15 calls (444s; 2 more in the post-fix reviews_200 run); OLD 2 over 27 calls.

OLD for c1, u1 and s_profile includes the interleaved re-runs (1 cold + 1 warm).

  • c1, comments. Cold ≤3 s via the API: met (1.80). Warm ≤2.5 s: missed (6.40, the mean of 1.15 and 11.65; the 11.65 s call got a withheld first API page, fell back to the browser in 9.5 s, inside the 15 s fallback bound). After the withheld-page retry was added, one warm call took 3.72 s and an in-process run had the API answer 12 of 12, comments p50 1.6 s.
  • t1, trending. Cold ≤3 s: met (1.75). Warm ≤2.5 s: met at p50 (2.22); max 2.93 (a slow TLS on the warm-up GET).
  • u1, user_search. Cold ≤9 s: missed (10.9; the first /api/search/user body came after 7 s, empty, and was recovered in the page). Warm ≤7 s: met at p50 (5.62), max 7.32; post-fix 6.44. The tighter targets that assume TT-9 (≤5 s warm) are missed; TT-9 is deferred.
  • s_profile. Cold ≤10 s: met in the A/B (6.07); missed in the one post-fix run (13.3 s: the first draw held its page 7 s with no XHR, and the hedge won). Warm ≤6 s: missed narrowly (6.08 / 6.17).
  • s_hashtag. Cold ≤9 s: met (6.04). Warm ≤6 s: missed (6.55 / 6.79; post-fix 5.78, n=1). Goto to first XHR is 5.8-6.8 s per page, which TT-9 (deferred) targets.
  • s_videos, 3 URLs. Cold ≤2 s: missed (7.92; one exit hit the 5 s connect cap and rotated). Warm ≤1.8 s: missed (2.04 / 2.59). The 2 s page hedge added afterwards was checked in process only: 6 batches at 1.82-3.06 s. The 1-URL targets were not measured.
  • Parity (parity.md): every input OK. Only data-bug fields changed (textLanguage, isAd and isSlideshow 0% to 100%; mentions 0% to 67%), with no key-field mismatches on overlapping ids.
  • Blocks here are block-signal log lines (empty or non-JSON bodies, browser fallbacks, rotations, hedges). NEW 16 over 18 calls, all recovered (0 error items; u1 hit an empty first body on every call); OLD 11 over 18 calls with 3 error items (no_comments once, no_users twice).

OLD for pydocs (cold only), five_urls and requests includes the interleaved re-runs.

  • example. Cold ≤1.3 s: met on 1 of 2 (0.73; the other cold call took 6.57 s: a dead first exit, a 5.0 s timeout, then a 1.5 s retry). Warm ≤1.2 s: met (1.20). Cold extract_ms 140 to 8.6 with the extractor warm-up.
  • pydocs, depth 1, 3 pages. Cold ≤6 s and ≤60 KB: met in the A/B (4.24 s, 48,987 bytes against OLD's 1,845,250). The one post-fix cold run took 8.44 s: its host log shows 1.0-1.8 s TLS per page and 5.3 s end to end for the 7.3 MB changelog page. Warm ≤5 s: missed (8.04 / 10.4; the root page and the changelog are fetched in sequence, on slow exits).
  • five_urls. Cold ≤4.5 s: met (2.28). Warm ≤3 s: met on 1 of 2 (2.94; the 7.40 s run had a dead-exit timeout).
  • not_found. Cold ≤1.5 s with status failed 'HTTP 404': status met, time missed by 0.11 s (1.61). Warm ≤1.2 s: met (1.03 / 1.15).
  • cf_challenge. No dynamic tier, real content or a clean failure: met (the real page through stealth in 28.6 s, no paid captcha; OLD returned the interstitial as success in 20.8 s).
  • requests, depth 1, 10 pages. Cold ≤7 s, no duplicate root: met (6.16; 10 distinct pages); one post-fix cold run took 7.57 s. Warm ≤6 s: missed (8.34 / 10.1; level 1's 9 pages run in 3 waves under the 4-per-host cap, and one run had a dead-exit timeout).
  • Parity (parity.md): item counts and URLs identical, except requests (OLD's duplicate domain root replaced by one more real page) and not_found (now FAILED). Field differences are the targeted fixes, except contacts.emails in two cases: changelog credits past the 1 MB HTML cap (the review fix now scans the whole raw HTML for emails), and an entity-spelled address fixed after the run.
  • Blocks: only cf_challenge has block markers (OLD 17 lines, NEW 24).

reddit and instagram

One host per arm, sequential calls, n=1 each (before_after.json for stage A, stageB.json for the final code, NEW only).

Call OLD NEW stage A NEW final Target Verdict
reddit scrape r/python, cold give-up 156.1 16.4 49.5 ≤20 s, clear error met in stage A; missed in the final run (2 of 4 warms hit the 15 s goto timeout)
reddit, while latched - 0.004 (2 calls) 0.0047 ≤1 s met
instagram details natgeo, cold 14.3 1.06 11.3 ≤3 s, clear failure met in stage A; missed in the final run (about 8 s warm GET on a slow exit, no rotation)
instagram details, while latched 21.4 (second call) 0.004 0.0036 ≤0.5 s met
instagram scrape /p/BsOGulcndj-/ 2.50 5.60 2.04 ≤3 s met in the final run; the stage A sample was a slow exit on the same request shape
instagram keyword discovery - - - ≤10 s not measured (IG-2 not done)

Items: 1 for the /p/ URL on both arms and 0 for the walled or closed endpoints; the /p/ item has the same values on both arms and NEW adds 10 documented fields. Rotations per give-up: reddit OLD 8, NEW 1; instagram details OLD 3 per target, NEW 0.

Data-bug fixes

google-search

  • resultsTotal on page 2+ read the page number; it now reads the count in any grouping and language, including ja/zh full-width timing parentheses and page-2 forms (review fix).
  • Dates ending in ' —', star ratings parsed as dates, and 'Read more' in descriptions are fixed.
  • AI Overview sources were always []: parsed (6-15 per page) and resolved to real URLs by default (3-18 per page live).
  • displayedUrl null on forum and social cards: falls back to the resolved URL's scheme://host (fill 1.00).
  • countryCode was stamped 'US' when no gl was sent: gl=us&hl=en are sent by default and stamped as sent.
  • site: ignored by Google: off-site results are dropped, then one re-render, then a SearXNG fallback; when both fail, resultsTotal, ads, products, PAA and AI Overview are cleared too (review fix).
  • PAA answers missing after a captcha solve: settle runs before expansion (NEW cold after /sorry 4 of 6 answered, OLD 0 of 4).
  • AI Overview read once its text holds for 500 ms (capped at 2 s); 'Show more' is looked up again after the PAA wait (review fix).
  • Agent text: compact pages beyond the third, so 13 of 25 measured pages fit instead of 2 (review fix).

indeed

  • A direct /viewjob URL gave jobKey null: it now gives jobKey and a canonical jobUrl.
  • Detail salary was lost: read from salaryInfoModel, then the company tab, then the header; a card's missing salary subfields are filled from the detail (review fix).
  • Direct /viewjob items gain companyRating, companyReviewCount, jobTypes and country, and join the cross-target jobKey dedupe.
  • companyUrl no longer carries tracking parameters, and enrichment only fills blanks; company-page rating 0 / count 0 read as unknown.
  • A 403/429 page with no wall markers was parsed as an empty jobs page; it now rotates.
  • A missing detail model falls back to the job page instead of an item with no description.
  • A null inline answer no longer decodes the next JSON object on the page (review fix).
  • Agent text: descriptions clipped to 600 chars, so 25 detailed jobs fit (review fix).

youtube

  • search_queries were dropped when urls were also given.
  • Search text and titles were cut to the first run; viewCount and likes were rounded (now exact).
  • hashtags held the hidden SEO keywords; keywords move to a new keywords field.
  • Durations normalised to HH:MM:SS across sources; LIVE and SHORTS badges become None.
  • isChannelVerified missing on search items and None for artists; the watch page no longer picks up other channels' badges.
  • Reply pagination stopped after page 1 (YT-5); voteCount and replyCount were None instead of 0.
  • The playlist fetched one page past the limit; items now come out in input order.
  • The translation request fired without subtitles.
  • Videos-tab relative times spelled out ('Streamed 8y ago' becomes 'Streamed 8 years ago').
  • Agent text: with subtitles, each video's transcript gets its share of the text cap (review must-fix; see Deferred).

google-maps

  • textTranslated was the truncated preview; it now comes from the full translation, with translatedLanguage set.
  • '
    ' and HTML entities in review text, translations and owner replies.
  • Rating-only reviews returned text and originalLanguage as ''.
  • address started with the place name.
  • phoneUnformatted was always null (now E.164).
  • kgmid was missing on review items.
  • likesCount documented as unavailable (null, not 0).
  • Name-only URLs with @lat,lng resolved to the wrong place (a Starbucks in Bend, OR for a Times Square URL).
  • A 429/403, sorry page or dead exit silently returned no data: it rotates up to 2 times, then the source becomes an error item naming the input.
  • One place's refused detail or reviews request no longer replaces the whole search with one error item; the place keeps its search fields (review fix).
  • A refused review header keeps the reviews; review text quoting a sorry or sign-in URL no longer counts as a wall (review fix).

amazon

  • listPrice read only from the struck-through price and only when greater than price.
  • Sponsored /sspa/click cards no longer become product_not_found or trigger extra pages.
  • Search positions count accepted cards in page order; detail pagination no longer skips the rest of page 1 after a failed detail.
  • Search reviewsCount read from the aria-label ('89.7K' was cut to 897), in any wording (review fix).
  • isAmazonChoice and isBestSeller require the real badges.
  • Duplicate ASINs removed; best-sellers parsed from the real cards (10 distinct with prices, was 4 with none).
  • Price, stock and delivery on the price-less fallback PDP; any price-less page takes the card price; the fallback page is recognised in any language (review fix).
  • AOD offer prices read from the right nodes; the pinned offer is row 1; reviewsLink '#...' becomes the reviews URL.
  • zip_code silently ignored: a failed setup is reported and cached for 5 minutes; items carry the location of the page they came from (review fix).
  • Short links follow Amazon's own redirector; agent text adds author, stock text and 6 spec rows (review fix).

walmart

  • Variant products reported 0 stars and 0 reviews.
  • HTTP 444/403, 5xx and a redirect to /blocked were taken as pages; they now rotate (OLD lost 140 of 200 reviews to one 520). A slug that merely starts with 'blocked' is no longer a block (review fix).
  • Detailed items lost the card's sponsored flag and search provenance; a failed detail now returns the card with detailsError.
  • Duplicate reviews at page boundaries (NEW 200/200 unique); reviews of other variants carry reviewedItemId/Name.
  • specifications and fulfillment were always null.
  • Lone surrogates in review text broke serialisation; agent text shows 200 of 200 reviews (review fix).

tiktok

  • parse_video maps textLanguage, isAd, isPinned, isSlideshow, mentions and slideshow mediaUrls.
  • user_search no longer reads 'Business account' as verified.
  • An empty first user-search body is recovered in the page instead of ending as no_users.
  • Geo-blocked and login-bounced exits are detected and end the attempt at once (and burn the pooled context).
  • A withheld comments API page, including a later page, is asked once more on another exit (review fix).
  • Interaction failures logged at WARNING with stage and URL; the no_comments message says the comments were withheld.

web-crawl

  • Output ignored max_length: links capped at max_links (200) and contacts at 50, with totals (the 3-page crawl reply went from 1.85 MB to 49 KB in the A/B).
  • GitHub and GitLab URLs were filed as social.
  • 404 pages and Cloudflare interstitials returned as success; errors said 'empty extraction' instead of 'HTTP '.
  • loadedUrl ignored redirects and links resolved against the pre-redirect URL; redirect duplicates dropped, never a start URL (review fix).
  • metadata.date was the oldest plausible date; now the latest, with a footer-date fallback (3/3 and 10/10 pages dated post-fix) (review fix).
  • Sphinx/MkDocs permalink anchors leaked into titles; the stealth tier could return raw HTML as markdown.
  • Entity-spelled emails found again; emails in capped pages read from the whole raw HTML (review fix).
  • 502, 504 and 520-526 retried on a browser tier; an SPA 404 fallback that navigates away reads as its page (review fix).
  • Agent text: every page gets a byte share of the 32 KB text after JSON escaping (review fix).

reddit / instagram

  • reddit's give-up took about 2m50s (156.1 s on OLD); it now takes 16.4 s cold (49.5 s in the final run) and about 4 ms while latched, with an error naming the countries and the next check time.
  • instagram's login-wall error told callers to give a profile URL they had already given; it now names the walled endpoint and points to /p/ and /reel/ URLs.
  • instagram add_parent_data (never implemented) removed from the schema; items go through to_output(), so isPinned, musicInfo, paidPartnership and the other declared fields appear.
  • reddit reports each warm and fetch as a progress stage; both plugins give the agent each item as one JSON line.

Kill switches

Defaults below were read from the code in the worktree (plugins/remote/proprietary, plugins/remote/host, plugins/remote/mcp_server, non-test files). All are read at import or startup, so a change needs a host restart. "Opt-in" means off by default.

Deferred and not done

From the plan (deferred):

  • Plain-HTTP replay of Google SERPs: ruled out (the replay returned the 437 KB JS shell with 0 results).
  • A curl_cffi tier in front of Indeed's browser: Cloudflare answered managed 403s on 4 of 4 and the non-browser traffic seemed to taint the browser's exit; a kept-context browser search takes about 1.3 s anyway.
  • Google organic-only as the default: a product decision (PAA would disappear); the opt-in flag is GS-6.
  • An active google-search warmer while the host is idle: spends proxy and captcha credit with no traffic; decide after reading prod cold-call frequency.
  • One keep-alive session across a call's detail fan-out on Walmart/Amazon, and cross-call reuse there: Walmart details on one shared IP were all blocked in 1 of 3 trials (failures correlate); the Amazon evidence is n=1.
  • TTL result caches: nothing shows users repeat calls, and cached prices and stock go stale.
  • A cookie and clearance cache keyed by exit (S11): no consumer is left.
  • A process pool for trafilatura and CPU-heavy parsing: add only if the soak shows /health loop-lag p99 above 20 ms; it costs 60-80 MB per worker.
  • trafilatura fast=True: byte-identical output was checked on 7 pages only.
  • Raising GOOGLE_SEARCH_MAX_CONCURRENT_PAGES or SCRAPING_MAX_BROWSER_PAGES above 4 and 6: the prod container's memory limit is unknown.
  • YouTube scrape via WEB /player plus /next: the WEB /player returns UNPLAYABLE, so isMonetized and the playability flags would regress.
  • Replacing dateparser in YouTube: unreachable today (server.py does not expose the date cutoffs).
  • Amazon: no Google referer on PDPs, or skipping the /clp redirect chain: PDP behaviour without a referer is unmeasured; the redirected path gave a full page 5 of 5 times.
  • TikTok: reusing anonymous msToken/ttwid cookies across calls: it would share one anonymous device across users.
  • New data paths for Reddit and Instagram profiles: the endpoints are closed to anonymous callers; that is research, not speed work.
  • A job runner or async jobs for very large calls: needs a queue, storage and result polling.
  • A second host replica and a Redis-backed /progress store: prod runs one copy.
  • Excluding text/event-stream from Traefik compression: buffering is inferred, not observed; verify first (see Deployer notes).
  • App: skipping the MCP discover probe for SurfSense's host: saves about 40 ms once per 5-minute check.
  • App: a timed background check refresher: checks never run on a schedule (egress consent); A-3 runs the check after a turn.
  • google-maps popularTimesHistogram, imageCategories and the likesCount slot: data gaps that need a fresh browser capture of the place RPC.
  • Walmart Next.js /_next/data route and stopping the download early: ruled out (the pages use getInitialProps and NEXT_DATA is the last 71% of the body).

Not done, per plugin and shared module (not_done):

  • google-search
    • GS-6 (commit-level navigation on the shared pool, include_people_also_ask=false): not done; it needs a block-rate A/B over at least 10 renders per arm with captcha credit. fetch.py keeps its own AsyncStealthySession meanwhile.
    • GS-7: lives in captcha/solvers.py; the SW-7 owner moved it to a kept client and 1 s polling, nothing is left in google_search.
    • GS-8 prod step: set REDIS_URL on the prod plugin app (see Deployer notes).
    • GS-9: deferred with SW-5.
    • Cold-pool head render (first page alone while no warm IP exists): offline-tested; no cold multi-query call was re-run.
    • Video cards: still skipped (optional in the plan).
  • indeed
    • IN-6 soak (30 calls over 20 minutes): not run; kept-context reuse was exercised across 12 warm calls and 9 in-process fetches.
    • Browser pre-launch at startup: not added on purpose (the block_webrtc profile is about 300 MB idle; a first-call launch was about 0.5 s here).
  • youtube
    • YT-6 partial: parse_video_page went from 72 to 31 ms (the plan's target) without the pre-extracted signature and targeted dig paths.
    • Hedge delay by connection state: kept at 2.5 s (HTML) and 1.5 s (InnerTube); SessionHolder exposes no public 'connection open' flag.
  • google-maps
    • GMP-9 shortlink probe not run; shortlinks still render through _fetch_html_stealthy.
    • The shortlink render still calls StealthyFetcher through asyncio.to_thread, not browser_pool.run (rare path).
    • GMP-10 stays off until the GMP-7 A/B and a prod watch.
    • s4, r1 and r5 not re-measured.
    • GMP-6's optional ftid and the plan-deferred fields unchanged.
  • amazon
    • AZ-11: only the #id fast path; scoping the remaining selectors (about 90 ms of CSS per PDP) and a single-pass variant regex (about 22 ms) need output-equality checks.
    • AZ-9 CSRF: the home page returned 202 on every exit (3/3 in stage B, 16/16 in stage A), so the location flow has never been seen working live; a failed zip is reported.
    • No live re-run after the AZ-11 fast path and two projection tweaks (parse CPU and text only; 94 tests pass).
    • c3 residual null price: a 4.8 KB AOD 200 with no offers is not treated as blocked (a request-shape change, not planned).
    • Seller enrichment: /sp?seller= returns a 152-byte 200 on both arms.
  • walmart
    • WM-2 stays off (WALMART_CANONICAL_URL=1 opts in); seeding the redirect hop's cookies was not tried, so every product page pays the 301 hop (0.75-2.2 s).
    • search_details, three_urls (cold) and reviews_200 targets missed; per-worker keep-alive holders would save about 0.4 s per page but reuse IPs across pages, a gated shape change.
  • tiktok
    • TT-9: deferred (SW-5); it targets the remaining 5.8-6.8 s goto-to-first-XHR on listing pages.
    • TT-7 Linux headful check: not run (see Deployer notes).
    • TT-8: concurrent targets get separate IPs but the same country, not a different country each.
    • No tool-call re-measure after the withheld-page retry and the 2 s page hedge (in-process checks only).
    • Comments: a video with truly 0 comments still pays one browser round before no_comments.
  • web-crawl
    • WC-7 stealth tier on the pool: the pool cannot reproduce StealthyFetcher's block_ads domain list or report the final status after a solve; the tier stays on StealthyFetcher.
    • WC-6 per-host holder (flag + A/B): not started; it would save CONNECT+TLS (0.74 s p50, 2.27 s max) on same-host pages.
    • Hedged static fetch (not in plan): 3 of 65 static attempts met a dead exit (5 s plus a retry) and set every NEW warm max; it needs the gate.
    • Dead-port target (6.7 s): unchanged; the proxy answers a refused port with 403, which is retryable.
  • reddit / instagram
    • RD-2: not done; moving the holder needs the warm on the browser pool with a leased sticky exit, and logged-out .json is closed so parity cannot be checked.
    • IG-2: out of scope for this stage.
  • shared-http
    • Removing the plugins' own holder and fan-out copies was left to the plugin agents (reddit's _RotatingSession remains, see RD-2).
    • Declaring curl_cffi and orjson: since done; host/pyproject.toml in the worktree lists curl_cffi>=0.16.3 and orjson>=3.13.0.
  • shared-browser
    • scrapling pin: since done; host/pyproject.toml in the worktree pins scrapling[fetchers]==0.4.15.
    • Plugin migration onto the pool: left to plugin agents; GS-6, the web-crawl stealth tier and RD-2 have not moved.
    • Live orphan check: in the live smoke one Chromium child outlived close_all briefly; cleanup was verified offline only.
  • shared-host
    • SW-8 calls-in-flight progress record (app item A-9): later.
    • Plugin adoption of shared_access, tool_result, stage and lifespan was left to plugin agents; every plugin server.py in the worktree now uses tool_result.

Review items left open (fix.not_fixed and fix_not_fixed):

  • google-search
    • PAA answered-count regression: the maintainer has to choose speed or PAA completeness (800/3000 ms gave parity at a 15.2 s warm render); both values are env-tunable.
    • AI Overview not re-measured over 5+ warm calls per arm against OLD (n=4, rust only).
    • The ja/zh resultsTotal fix is covered by unit tests, not a live call.
  • indeed
    • Reporting the pool's kept-key and plugin-gate waits as progress needs a browser_pool hook.
  • youtube
    • The fix stage stalled. Code for both must-fix items is in the worktree (the seen guards in innertube.py and subtitles.py; _video_sharing_cap in server.py) and the package tests pass (145), but no reviewer re-checked them.
  • google-maps
    • GMP-7 is on by default without the reviewer's 120-vs-120 holder A/B; watch for reviews-RPC 403s.
    • e10 cold (10.5 s, 3 hedges for 21 requests): the search went to a hedge and the kept session opened 9 new connections before HTTP/2 was up (SW-2 behaviour).
  • amazon
    • The AOD Sec-Fetch-* headers are still navigation-shaped; changing them needs a gate. The search no-referer default rests on 12 fetches per arm plus sequential evidence; the AOD and PDP shapes were never gated.
    • No progress message per location-setup try (worst case about 96 s between messages during the mint).
  • walmart
    • WM-5 contract: a listing product whose page fails is returned as its card with detailsError and counts toward max_items; it is not replaced by the next card.
    • (Fixed after the run: the shared hint now says only that the reply is full.)
    • A known-end review walk where every page repeats is bounded by the named last page (at most 500), not by maxReviews.
  • tiktok
    • XHR-shaped headers for the comments and Explore API GETs: a fingerprint change that needs a gate.
    • Skipping the browser for a zero-comment video: needs a live zero-comment sample.
    • Trending retries only the first Explore pull on a fresh exit.
  • web-crawl
    • An SPA 404 fallback that never navigates (copied index.html, replaceState) still ends FAILED 'HTTP 404'.
    • Resource soak and a live stealth-tier check after the launch gate: not run.
  • shared-http
    • Double rotation is fixed only for callers that pass seen (opt-in).
    • A task that outlives its holder block can still start a request on a holder already back in the idle pool.
  • shared-browser
    • No live verification of the fixes (60 offline unit tests plus an offline real-Chromium probe).

Deployer notes

  • Env knobs that matter in prod. The pool caps (browsers 3, pages 6, kept contexts 4, HTTP 48) and idle timers (600 s / 1800 s) set memory and proxy load on the single prod host; raising pages is deferred until the Coolify memory limit and a soak RSS are known. SCRAPING_HEDGE=0 and SCRAPING_MAX_IDLE_SESSIONS=0 are the global rollbacks for hedging and cross-call reuse.
  • REDIS_URL for google-search. google_search/pool_store.py shares warm IPs through Redis. When a fresh IP's /sorry solve succeeds, its GOOGLE_ABUSE_EXEMPTION cookies are published under surfsense:google-search:warm:<sha1(proxy)> with a TTL of GOOGLE_SEARCH_EXEMPTION_TTL_S (3600 s). When the pool needs a new IP, fetch.py first calls adopt() and takes a warm IP not already in the pool before vetting and solving a fresh one; walled or failed IPs are evicted. Without REDIS_URL, or with Redis unreachable (1 s socket timeouts), every store call is a no-op: the warm pool lives only in process memory and is lost on each restart or redeploy, so the first calls after a deploy pay vet plus solve again. Set REDIS_URL on the prod plugin app in Coolify. The stored values contain proxy URLs with the vendor's credentials, so the Redis instance must be private.
  • SSE through the Coolify proxy. SW-8 progress notifications only help if the reverse proxy passes text/event-stream through without compressing or buffering it. Buffering is inferred from headers, not observed. Check once with a licensed curl -N --compressed call that timestamps each event; change the Traefik labels only if events arrive in bursts.
  • Linux headful check for TikTok. TT-7 needs a live profile run in the Linux container with CRAWL_HEADED_XVFB_ENABLED=TRUE before merge; only Windows headless was measured. In prod TikTok uses two launch profiles (headful for profile, hashtag and search listings; headless for user search and fallbacks). With Indeed's and Web Crawl's profiles in the same pool (Google Search keeps its own browser outside it), that is 3-4 distinct launch profiles against SCRAPING_MAX_BROWSERS=3, so a fourth evicts the least recently used idle one; either raise the cap or confirm the eviction churn is acceptable. Record one cold launch_ms in the container to replace the unmeasured "about 5 s".
  • Block-rate gates below the protocol's 30 fetches per arm. These changes are on by default and rest on small in-process gates; watch the prod fallback, block and empty-draw counters for 48 h:
    • google-search GS-1/GS-3: precheck 10 per arm, OLD 10/10 usable, NEW 8/10 (one 429-walled IP, one 5 s connect timeout); /goto 20 links per arm, 0 blocked on both.
    • indeed IN-1/IN-6: 10 search fetches per arm. OLD 10/10 ok with 5/10 meeting a challenge; NEW 9/10 ok with 2/10 challenged, and one fetch failed after 4 attempts in 61 s. spa=1 answered 200 on 27/27. Too small to call; the IN-6 soak was not run.
    • youtube YT-2: 12 videos, NEW 0 blocked in 23 requests (11/12 ok) against OLD 4 blocked retries (10/12 ok); an earlier 10-video run had OLD at 9 blocked and an unusable NEW count. YT-9: kept holder 0 blocked in 12 attempts against fresh holders 3 in 17.
    • amazon AZ-3: search 12 per arm, OLD (Google referer) 8/12 blocked against NEW 4/12 plus 2 TLS errors; PDP transport 10 per arm, OLD 1/10 against NEW 2/10 (one-sided Fisher p = 0.5, computed here). The AOD and PDP header shapes were never gated.
    • walmart (transport): 14 fetches per arm, 1 blocked request each.
    • tiktok TT-1 comments API 0/10 against browser 1/10 (p=1.0); TT-2 Explore API 1/10 against browser 0/10 (p=0.5); TT-4 media blocked 0/10 against open 0/10 (p=1.0); after the withheld-page retry, both APIs 0/6.
    • web-crawl WC-6 static transport: 10 URLs per arm, 3/10 blocked on both (p about 0.66).
    • google-maps GMP-3/GMP-7 ran at the full 30 per arm (0/30 on both) plus 20/20 for the cookie-jar check; the live NEW 2/132 against OLD 0/169 gives p about 0.19. The reviewer asked for a 120-vs-120 holder A/B before GMP-7 stays on by default; it was not run (GOOGLE_MAPS_KEEP_ALIVE=0 reverts).
  • Left off by default pending a bigger gate: WALMART_CANONICAL_URL (WM-2: 11/26 against 1/27 blocked, p about 0.001), GOOGLE_MAPS_KEEP_IDLE (GMP-10), the TikTok XHR-shaped API headers and the Amazon AOD Sec-Fetch-* headers (not shipped), and the web-crawl per-host holder (WC-6, not built). GS-9 and TT-9 wait on SW-5.
  • Cross-call reuse is opt-in. YOUTUBE_KEEP_IDLE was on by default in the run and is now off, like GOOGLE_MAPS_KEEP_IDLE (its gate was 12 fetches per arm). GOOGLE_SEARCH_GOTO_AI_SOURCES=1 stays on: it resolves the AI Overview and AI Mode source links (goto.py), which fixes their always-empty sources; 0 holds it back.
  • Where the knobs are listed. plugins/remote/host/.env.example now lists every speed setting and kill switch, shared and per plugin, with its default, and says Google Search uses REDIS_URL for its warm IPs.
  • Memory for the pool caps. The soak on Windows peaked at 220 MB for the host python and 1.6 GB for the whole tree with Chromium (soak.md). Read the prod container's own peak before raising SCRAPING_MAX_BROWSER_PAGES or GOOGLE_SEARCH_MAX_CONCURRENT_PAGES.
  • youtube-transcript-api. youtube/subtitles.py imports the private youtube_transcript_api._transcripts._TranscriptParser, and host/pyproject.toml allows youtube-transcript-api>=1.0.3. Run youtube/tests/test_subtitles_native.py before any version bump, or copy the roughly 20-line parser into the plugin.

Final smoke and soak

Run on the integrated branch after every fix, on one dev host with all plugins mounted (no PLUGINS filter), real proxy (DataImpulse) and captcha (CapSolver), license stubbed. Raw records: final_smoke.json and soak.md in this folder, plus integrate/ for the replies and host logs.

Smoke. /health answered 200 in 14 ms; GET /web-crawl/mcp answered 405. One cheap call per tool of the eight listed plugins, one at a time, 14 calls, all answered with items and no tool error. Every reply's text carries the data an agent needs, not only titles: organic snippets, People Also Ask answers and the AI Overview; page markdown; full transcripts for all three videos; comment, review and job text; prices, features and specs; bios and follower counts. The largest text was 31,112 bytes (YouTube search with three transcripts), under the 32,000-byte cap; no reply needed the "more items not shown" line.

  • google-search 78.3 s is the cold path: the first IP needed a reCAPTCHA solve, and CapSolver took 59.3 s to harvest the token (61.6 s in all). The render then reused the solved IP; 18 result links were all resolved during the render.
  • web-crawl 30.8 s: one depth-1 page (docs.python.org's changelog, 7.3 MB of HTML) hit the static tier's 15 s cap with 655 KB received, and the browser tier then read it in 13.5 s. The other two pages took 1.0 s and 2.3 s over plain HTTP.
  • indeed 14.4 s: the first navigation on the kept indeed:us context timed out at 12 s, the context was burned, and the retry on a new exit answered.
  • amazon 11.5 s: one product page got a TLS handshake failure on a new connection (the known 10-15% on this gateway) and was retried; 3 products, 0 error items.
  • Google Maps reviews: two of five reviews are rating-only at the source, so they carry no text; the three with text show it in full.

Soak. A fresh host of the same kind ran 16 mixed calls in two lanes: Chromium calls (google-search, indeed, tiktok scrape and user_search) one at a time, and plain-HTTP/API calls (web-crawl static pages, tiktok trending) beside them. So at most two calls were in flight, and at most one of them used a browser. All 16 answered. The budget was spent in 3.7 minutes, not the planned ~5. Peak host python RSS was 220 MB (154 MB at start, 210 MB at the end). The whole process tree, Chromium included, peaked at 1,606 MB and fell back to 1,209 MB. Chromium processes peaked at 15 and patchright node drivers at 2. Warm paths showed: Google Search's second and third calls reused the pool IP solved by the first (calls of 13.3 s and 8.6 s, after 33.2 s cold with a 16.3 s solve), and Indeed's second call took 4.1 s on the kept context, after 25.8 s cold.

/health under load: p50 1.7 ms, p99 25.4 ms, max 63.4 ms (1,117 polls, none failed). Idle on the same host right after: p50 2.7 ms, p99 29.8 ms. The tail comes from this Windows machine (timer resolution, the process sampler, other test runs), not from the plugins. So this run cannot test the plan's trigger for a parse process pool (p99 over 20 ms). Measure event-loop lag on the Linux prod host before deciding.

Stop and orphans. Windows refuses taskkill without /F for console processes, so both hosts were stopped with taskkill /F /T after a 10-12 s wait (16 and 15 processes ended). Afterwards none of the recorded PIDs was alive, no Chromium, node or python process with ms-playwright, patchright or dev_host in its command line remained outside the pre-run baseline, and port 8120 was free. A forced stop skips the lifespans, so this checks that /T reaps the browsers, not the graceful close path. On Linux, a SIGTERM runs the lifespans.

📝 Walkthrough

This pull request adds shared scraping infrastructure and updates the host and multiple plugins. It changes plugin lifecycle and MCP request handling, scraper transport and concurrency, parser output, progress reporting, and tool-result formatting.

Changes: Shared plugin platform

Layer / File(s) Summary
Host lifecycle and MCP routes
plugins/remote/host/*
The host runs optional plugin lifespans in background tasks, closes them in reverse mount order, and rejects GET and DELETE requests to /mcp with 405 responses.
Shared scraping and MCP utilities
plugins/remote/mcp_server/*, plugins/remote/proprietary/scraping/*, plugins/remote/proprietary/license_check/*
Shared utilities provide HTTP and API clients, browser and proxy-session pools, ordered concurrency and hedged requests, challenge handling, shutdown cleanup, result formatting, progress reporting, and shared license access.

Plugin scraper updates

Layer / File(s) Summary
Product and job scraping
plugins/remote/proprietary/amazon/*, plugins/remote/proprietary/indeed/*, plugins/remote/proprietary/walmart/*
Amazon adds location sessions and concurrent product enrichment. Indeed uses pooled browser contexts and batched spa=1 job details. Walmart adds concurrent product and review fetching and variant data parsing.
Search and place scraping
plugins/remote/proprietary/google_search/*, plugins/remote/proprietary/google_maps/*
Google Search adds parallel page rendering, link prefetch, locale defaults, and site-filter handling. Google Maps adds place-resolution caching, concurrent source jobs, refusal handling, and language-aware review parsing.
Social and media scraping
plugins/remote/proprietary/instagram/*, plugins/remote/proprietary/reddit/*, plugins/remote/proprietary/tiktok/*, plugins/remote/proprietary/youtube/*
Instagram adds endpoint login-wall latching. Reddit adds closed-endpoint detection. TikTok adds API-first comments and trending retrieval and concurrent work. YouTube adds native subtitle retrieval, concurrent finalization, and bounded comment-reply collection.
Web crawling
plugins/remote/proprietary/web_crawl/*
Web Crawl updates its crawl ladder, adds concurrent breadth-first crawling, caps returned links and contacts, and adjusts contact and URL classification.

Priority: ➖ Normal

Estimated code review effort: 5 (Critical) | ~120 minutes

Merge Risk: ⚪ Minimal · up to 433d2

No concrete issue remains that would prevent merging after normal checks.

Security architecture risk: 🔵 Low · up to 433d2

The reviewed request paths preserve access checks, and the shared-state controls limit the observed exposure. However, disabling plugin lifespans also disables explicit shutdown cleanup for shared resources. A fixture privacy question remains unresolved.

Retained concerns

  • Low · reliability · observed: The new PLUGIN_LIFESPANS=off mode still serves tools but skips the lifecycle exit that closes lazily created shared browser and idle HTTP pools. Explicit shutdown reclamation of contexts, connections, and associated leases therefore depends on external process termination in this mode. Lifespans are enabled by default, limiting the concern to the disabled configuration.
Security review details

Security Blast Radius

  • inferred — The retained cleanup concern affects shared resources within a serving host process when lifespans are disabled. The evidence does not establish cross-tenant disclosure or exposure of authenticated user browser state.

Security Findings and Attack Paths

  • observed — The deferred YouTube candidate concerns a newly added fixture containing a mentioned-account handle and channel identifier outside the reply-author anonymization assertion. The parser propagates comment text, but whether the mentioned account identifies a real private person remains unresolved. This is not a verified privacy finding or production attack path.

Trust Boundaries and Controls

  • observed — The paid-plugin access check still runs before the MCP server receives forwarded requests. The new method wrapper rejects unsupported streaming requests before that check; it does not grant tool authority.
  • observed — Indeed retains anonymous clearance state across callers, but navigation is restricted to supported Indeed hosts and paths. Browser contexts are fresh by default; retained Indeed contexts are retired on failures. Idle HTTP reuse is keyed by plugin and exit, and cookies are cleared before retention.

Resilience and Maintainability Implications

  • observed — The changed Google refusal classifier checks parsed host and path rather than arbitrary URL text. Its /goto consumer checks both the response URL and redirect location, avoiding classification based only on a query containing /sorry/.

Hardening Proposals

  • proposed — Separate optional warm-up from mandatory host-owned shared-resource cleanup, so disabling warm-up does not remove reclamation of browser contexts and connections.

is available, send the request through get_geo_proxy_url(country) via _request
instead of failing the hedge task. Preserve the existing leased-exit handling
when a lease is returned.

Review comments at @plugins/remote/proprietary/google_search/goto.py:
- Around line 78-81: Update `_blocked` to identify the Google `/sorry` wall by
checking the parsed URL’s host and path, rather than searching for a `/sorry`
substring. Apply the check to both `response.location()` and `response.url`,
accepting only Google hosts with a path beginning `/sorry`, and add the URL
parsing and relative-URL resolution imports needed for this check.

Review comments at
@plugins/remote/proprietary/indeed/tests/fixtures/search_page_jobcards.html:
- Line 1: Replace the live `ad=` token values in the three sponsored
`viewJobLink` entries in the fixture with `SCRUBBED`, leaving the rest of each
link and the fixture unchanged.

Review comments at @plugins/remote/proprietary/walmart/fetch.py:
- Around line 154-168: In the fetch_page redirect-following loop, return
_Refused when the loop finishes with target still non-None, indicating the
redirect limit was exceeded. Preserve the existing handling for completed
redirects and blocked responses.

Comment thread docs/architecture/plugin-host.md Resolved
- Google Search: Google's sorry wall is recognised by host and path, not a
  "/sorry" substring, so a result linking to a page with "sorry" in its URL
  no longer burns the wave's exit (goto and the captcha check share
  captcha.is_sorry_url).
- Walmart: a redirect still pending after the last allowed hop is a refused
  try, so the next exit is tried instead of reading an empty page.
- Amazon: a hedge whose sticky lease is unavailable falls back to the
  gateway instead of spending the call's hedge budget on nothing.
- Fixtures: live tracking and session tokens scrubbed from the captured
  pages (Indeed, Amazon, Google, Google Maps, TikTok, YouTube).
- plugin-host.md: shared_access() everywhere, and the Reddit and Instagram
  gaps now describe their fail-fast latches.
