dab3bb2437 feat(nadia): @nadia: Fix the two review findings in the research engine: (1) retry failed wor 
Outcome: done
Changed: src/typosaurus_sandbox/research/engine.py:108-111,156-163,173-177, src/typosaurus_sandbox/research/pipeline.py:20-23,187-234,296-312, tests/test_research_engine.py:186-290, tests/test_research_pipeline.py:292-354
Verified by: verify() -> "make verify" exit_code 0, "Ran 226 tests OK verification passed"; only pre-existing StarletteDeprecationWarning from fastapi/testclient.py import in tests/test_api.py, none introduced
Findings: Retry: pipeline.py:192-211 retries RsearchError status>=500 with backoff min(0.5*2^(attempt-1),8.0) up to RETRY_MAX_ATTEMPTS=3 (pipeline.py:20-23); status<500 or None not retried. Unexpected exceptions recorded as failure WorkOutcome in consume (pipeline.py:296-312), appended to outcomes. Closure gated on requests_failed==0 (engine.py:159-163); report.closed=requests_failed==0 (engine.py:177); failed round prevents closure, later clean round keeps report.closed False (tests/test_research_engine.py:229-290). Deep/ai wired: every popped query yields WorkItem("web",query,deep=True,ai=True) (engine.py:111); pipeline passes deep/ai to client.search and cache probe (pipeline.py:157-158,170-176); test proves seed+subtopic web calls all carry deep=True and ai=True (tests/test_research_engine.py:203-222). Fix committed as 472a59e; this node's working-tree delta is only trailing-blank cleanup; no new dependencies, client.py/cache.py/config.py/frontier.py untouched.

472a59e122 feat(tanya): Audit tests/ for skipped, disabled, or weakened tests 
Outcome: done
Changed: none
Verified by: PYTHONPATH=src python3 -m unittest discover -s tests -q -> "Ran 226 tests in 0.634s OK", EXIT_CODE=0
Findings: Criterion 1 PASS - grep for unittest.skip|skipIf|skipUnless|SkipTest|expectedFailure|pytest.mark.skip|pytest.skip|xfail|@skip|@disabled|pytestmark across tests/ returned 0 hits; case-insensitive skipif|skipunless|onlyif|not implemented also 0; runtime report shows no skipped/expected-failure suffix
Findings: Criterion 2 PASS - grep '^\s*(pass|\.\.\.)\s*$' returned 0 hits; AST scan of all 226 test_* functions found none with only-pass body and every one contains >=1 assertion (bare assert or self.assert*/fail* call)
Findings: Criterion 3 PASS - all 25 broad 'skip' grep hits individually inspected and are duplicates_skipped/cache counters or test names, not directives: tests/test_research_engine.py:132-136, tests/test_research_dedup.py:105-233, tests/test_research_scheduling.py:226-496, tests/test_research_client.py:426,434; bare 'return' at tests/test_research_scheduling.py:149,175,289 are worker loop-exit control flow (assertions at 157-162,183-186,298-300); tests/test_research_pipeline.py:333 tests exception handling with assertions at 344-351
Findings: Criterion 4 PASS - evidence recorded as file:line references above and stored in tree finding
Findings: Supplemental sweep for __test__|no cover|pragma|.skip(|mark. returned 0 hits; suite has grown to 226 tests (previous run 219) with no skipped/expected failures reported

808d6b4f83 test(sveta): Write unit and pipeline tests for the research engine 
Outcome: done
Changed: tests/test_research_engine.py:1-198 (new), tests/test_research_pipeline.py:1-276 (new), tests/test_research_scheduling.py:7,366-380, tests/test_research_integration.py:1-112
Verified by: make verify -> exit_code 0, "Ran 219 tests OK verification passed" (baseline 199); only pre-existing StarletteDeprecationWarning from fastapi/testclient.py:1, none introduced
Findings:
- tests/test_research_engine.py (5 tests, mocked FakeResearchClient, no network): single-round closure; two-round discovery-then-closure with web/images/chat/describe items and round-2 describe of round-1 URL; new-content-alone does not prevent closure (engine.py:196 closure = new_urls==0 and new_queries==0); report/round to_dict serialisable; empty-subject ValueError with zero client calls.
- tests/test_research_pipeline.py (13 tests): extract_response web/ai/deep/chat/describe (pipeline.py:69), apply_extraction counts (pipeline.py:133), per-kind cache probes (pipeline.py:170), chat cached=True marks outcome cache_hit, RsearchError 503 failure outcome with pool survival, all-four-content-types drained through one run().
- tests/test_research_scheduling.py: +2 cache-TTL expiry tests with mocked time.monotonic (post-TTL and exact-TTL boundary, cache.py:20-44).
- tests/test_research_integration.py: converted from live-rsearch probe to offline mocked transport (patched urllib.request.urlopen, canned fixture); all original assertions preserved (second run cache_hit=True with zero additional r

32a17e3f5c feat(tanya): Execute four recursive verification rounds and compile final report 
Outcome: done
Changed: none (read-only; rounds run via PYTHONPATH=src python3 heredocs)
Verified by: make verify -> exit_code 0 "Ran 219 tests in 0.968s OK verification passed"
Findings:
- R1 2026-08-07T23:31:17Z PASS engine-optimality: empty world closes round1 (lfp halt); chain4 -> 6 rounds/5 urls (no depth cap); dedup unique-only; S* size5 > F^2 size2.
- R2 2026-08-07T23:34:35Z PASS verifies R1: chain6 pool1 -> 8 rounds/7 urls, F^3=3 subset S*=7; content-only closes round2; fanout 2 urls/5 queries.
- R3 2026-08-07T23:35:02Z PASS verifies R2: pools 1/4/8 identical (8,7,14,1); cached 2nd run 0 network calls, identical report; pool_size==max_concurrency.
- R4 2026-08-07T23:36:26Z PASS verifies R3: stress 38 items=succ+fail, 4 content kinds, closed; ""/whitespace -> ValueError, zero calls; chain5 pool8 7 rounds/6 urls; slow client completes.
- Engine C1-C8 all PASS (sibling f7f10c64): rsearch-only, bound 8, one _request 4 content types, dedup 64->1, closure, annotations/logging/header, no TODO, verify green.
- Live probe (fde105db, "python asyncio"): 86 queries, 754 urls, 281 contents, 164 requests, $0.002075, 264.91s; no closure in 240s guard -> TimeoutError, 2835 enqueued.
- Rounds' initial failures were tester-expectation only (MIN_QUERY_LENGTH=2 frontier.py:13, description seeds, non-http tokens kept); engine correct; reflect() recorded.
Open: none for this node; PR creation deferred to run coordinator (deepresearch.md exists, sibling 7d91ddb)
Confidence: high - four round

14a60ef77f feat(tanya): Execute engine acceptance criteria and record per-criterion verdicts 
Outcome: done
Changed: none
Verified by: make verify -> exit_code 0, "Ran 199 tests in 2.168s OK verification passed" (only pre-existing StarletteDeprecationWarning from fastapi/testclient.py:1, not from the research package)
Findings:
- C1 PASS: grep non-rsearch URLs in research/*.py -> 0 lines; live tests.test_research_integration -> 1 OK, asserts all requested URLs start with https://rsearch.app.molodetz.nl
- C2 PASS: tests.test_research_scheduling -> 22 OK; peak == max_concurrency == 8 and pool bound asserted

bc11dc18b2 test(sveta): Write live integration test against the rsearch API 
Outcome: done
Changed: tests/test_research_integration.py:1-70
Verified by: make verify -> exit_code 0, 199 tests OK (1 new integration test), "verification passed"; only pre-existing StarletteDeprecationWarning from fastapi/testclient.py, none introduced; standalone run of tests.test_research_integration -> 1 test OK in 0.386s
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

3ff5fc686a test(sveta): Write unit tests for frontier scheduling and concurrency safety 
Outcome: done
Changed: tests/test_research_scheduling.py:1-506
Verified by: make verify -> exit_code 0, 198 tests OK (22 new), "verification passed"; only pre-existing StarletteDeprecationWarning from fastapi/testclient.py:1, none introduced
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

c0a59b4138 feat(nadia): Build content-type agnostic pipeline with bounded asyncio worker pool 
Outcome: done
Changed: src/typosaurus_sandbox/research/pipeline.py:1-280 (new), src/typosaurus_sandbox/research/client.py:30-52,98-99,124-148, src/typosaurus_sandbox/research/__init__.py:21-49
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

Verified by: make verify -> exit_code 0, 176 tests OK (36 new), "verification passed"; only pre-existing StarletteDeprecationWarning from tests/test_api.py, none introduced
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

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

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.

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.
