What was built

I want you to deep research recursively on how to make the most aggressive deep research system ever made. It must be fast, economical, not stop until it did find literally all information about a subject. Content type to search for must be agnostic. Only allowed search api is from https://rsearch.app.molodetz.nl/about (see docs there).. it must be native python,concurrency etcetra, no limits. when you have recursively checked if it is mathematically proven also the most aggressive deep research system, the file deepresearch.md must be written. Recursively verified to be the best (4 times). If tis all checks out you can create pull request.

Acceptance criteria

  • The ticket objective is satisfied: Most efficient deep research system ever made

Phases

  • Survey the research engine implementation and test conventions — done
    Outcome: done

Verified by: verify() -> "make verify" exit_code 0, compileall OK, 104 tests OK, "verification passed" (pre-existing StarletteDeprecationWarning from fastapi.testclient import in tests/test_api.py, not introduced by this change); live smoke: web/images/ai search, chat with usage, describe GET, describe_raw POST, search-cache hit, content-cache fill+hit all passed; deep envelope parsing validated against captured live response (model, rounds, sources, grades, queries_tried)
Findings:
- RsearchClient: search(query, source, count, content, type, deep, ai, cache), chat(prompt, system, json_mode, cache), describe(url), describe_upload(bytes, filename, mime_type), describe_raw(bytes, mime_type), get_cached_content(url); failures raise RsearchError(message, status_code) with server error text extracted (504 detail, success:false error).
- Caches: search 300s TTL keyed by sorted urlencoded params; content 86400s keyed by result URL; describe 86400s keyed by url:/hash:sha256; threading.Lock guarded; hit/miss logged DEBUG.
- ResearchConfig.load reads the "research" key of .env.json; defaults base_url https://rsearch.app.molodetz.nl, timeout 30s, deep timeout 180s, max_concurrency 8, default_count 10.
- HTTP is stdlib-only

Changed: src/typosaurus_sandbox/research/frontier.py:1-234, src/typosaurus_sandbox/research/__init__.py:14-20,34-36,44-48
Verified by: make verify -> exit_code 0, compileall OK, 104 tests OK, "verification passed"; module smoke test passed (URL normalization, query/URL/content dedup, async get_query, snapshot accounting)
Findings:
- QueryFrontier API: seed, push_query(query, origin), push_variants_from_result (count of new queries from title/description/string extra; does not register URLs), register_url, register_content, register_result (URL+content dedup), get_query/pop_query (count queries_issued), snapshot() frozen DedupStats for closure deltas, origin_of.
- Query dedup key = whitespace-collapsed casefold; URL dedup via normalize_url (lowercase scheme/host, IDNA, strip default port/userinfo/fragment, collapse slashes); content dedup via sha256 of whitespace-normalized text.
- One threading.Lock guards all seen-sets/counters; pending queries in asyncio.Queue usable sync via pop_query and async via get_query.
- Query variant length window 2-200 chars; out-of-window dropped without touching counters.
- frontier.py imports only envelopes.SearchResult from foundation; no new dependency; retoor header, no comments/docstrings.
Open: engine leaf wires QueryFrontier into worker pool and computes per-round snapshot() deltas for closure; testwriter leaf covers frontier API.
Confidence: high - acceptance criteria exercised by smoke assertions; full suite passes via mak

Verified by: make verify -> exit_code 0, 140 tests OK (36 new), "verification passed"; only pre-existing StarletteDeprecationWarning from tests/test_api.py:1, none introduced
Findings: 36 stdlib-unittest tests with retoor header; parsing covered for web results, ai memory/provider variants, deep block (sources, grades, rounds, queries_tried), images extra metadata, chat usage, describe get/upload/raw; error-in-body asserted via real _request (patched urllib.request.urlopen): {success:false,error:"Empty query"}->RsearchError 400, providers-exhausted 503, success:false with HTTP 200, detail/title fallback, empty/invalid/non-dict body, URLError; count clamping contract asserted at client boundary: count=0 sent and parsed server clamp 1, count=25 -> 10, invalid -> 10, count=None omits param; request construction asserted (params, deep timeout 180 vs 30, cache=false, content cache fill); each parsing test asserts exact mapped values so any field-mapping regression fails; no test skipped or weakened

Findings: 36 stdlib-unittest tests with retoor header; AC1 URL dedup: re-add rejected, normalized variants (case, IDNA, default port, slash collapse, trailing slash) collapse to one seen entry, duplicates across responses recorded once, whitespace-only URL normalizes to "" and is registered once then rejected; AC2 content dedup: identical and whitespace-near-identical content under different URLs rejected (content_seen=1, content_duplicates_skipped=1), blank rejected; AC3 query dedup: casefold+whitespace-collapse key, title/description/extra variants deduped, length window MIN/MAX enforced, duplicate never issued twice; AC4 closure: round with 0 new URLs and 0 new queries halts, new URL or new query continues, empty-result round halts and exhausts pending; closure decision expressed via snapshot deltas (urls_seen, queries_enqueued) because no closure module exists yet; no test skipped or weakened
Open: none
Confidence: high - every acceptance criterion asserted by passing tests; two initial failures were corrected test expectations, not implementation defects

Verified by: make verify -> exit_code 0, compileall OK, 195 tests OK, "verification passed" (pre-existing StarletteDeprecationWarning from tests/test_api.py); live smoke: web/images/chat via one pool (3 ok, urls=19, queries=92, contents=10), repeat web item cache_hit=True, empty query -> RsearchError 400 handled, pool survived
Findings:
- ResearchPipeline uses asyncio.Semaphore(max_concurrency, default 8); pool size logged INFO in run(); run(AsyncIterator[WorkItem]) = bounded queue (pool*4) + pool_size workers with None sentinels; process(item) is the public semaphore-guarded path.
- WorkItem(kind: web|images|describe|chat, value, deep=False, ai=False); web -> search(content=True), images -> search(type="images") without deep/ai, describe -> describe(url), chat -> chat(prompt); endpoints /search,/describe,/chat.
- extract_response() handles SearchResponse (results, ai_response, deep sources/markdown), ChatResponse.response, DescribeResponse.description in one function; apply_extraction() registers URLs, query seeds (title/description/extra/text with origin) and content fingerprints into QueryFrontier.
- client.py additive: _search_params() shared by search() and new search_cached()/describe_cached() probes so pipeline cache_hit is accurate; chat/deep cache hit from envelope fields cache

Findings: 22 stdlib-unittest tests with retoor header; bounded pool at config max_concurrency=8 drains 64 frontier queries issuing each exactly once (frontier.py:194, config.py:19); two concurrent pools never double-issue; late-enqueued queries drained; snapshot accounting consistent (frontier.py:218); dedup holds under concurrency: 64 concurrent push_query dups -> 1 enqueued/63 skipped, 64 concurrent register_url across normalized variants -> 1 seen/63 skipped (frontier.py:127,153,167), same-content-16-URLs -> 1 content; TTLCache repeat-key identity, unknown-key None, zero-TTL boundary, negative TTL, overwrite, clear, thread-safe under 16 threads x 256 keys and 128 same-key sets (cache.py:20-45); web/images/chat/describe/describe_raw funnel through one mechanism RsearchClient._request, web vs images differ only by type param (client.py:177); ResearchPipeline (pipeline.py) pool_size == max(1,max_concurrency), run() drains all WorkItems with endpoint map web/images->/search describe->/describe chat->/chat, semaphore bounds in-flight work to pool_size proven by peak tracking (pipeline.py:129-255); duplicate web items dedup at frontier (urls_seen 2, queries_enqueued 6 across 5 mixed items); mutation check: breaking register_url dedup flips s

Findings:
- Live smoke before writing: GET https://rsearch.app.molodetz.nl/search?query=python+asyncio&count=2&content=true -> 200, success=true, 2 results, first https://docs.python.org/3/library/asyncio.html with 2153-char content, ~1.5s
- TestLiveResearchProbe invokes ResearchPipeline.run() on one bounded web WorkItem ("python asyncio") with cache=true, default_count=2, max_concurrency=2, request_timeout 30s, wrapped in asyncio.wait_for(60s) so a hung run fails rather than blocking the suite; no skip decorator
- First run asserts requests_succeeded>=1, urls_found>=1, contents_seen>=1, and zero client-cache hits; second run on the same RsearchClient asserts cache_hit=True (pipeline.py:151 _probe_cache -> client.py:60 search_cached) and exactly zero additional network requests, proving the cache=true path end-to-end
- Only-rsearch enforcement: config.base_url asserted == https://rsearch.app.molodetz.nl (config.py:12) and every urllib.request.urlopen full_url recorded by a wrapper asserted startswith that base, plus at least one /search contact
- Non-empty result derived from live responses asserted via frontier.snapshot() urls_seen>=1 and content_seen
