Every claim is traceable to the run's +verified nodes (fact sheet node d5d9e290; optimality node b042b1d23; tester nodes f7f10c64, +fde105db, 2e6bd38b; engine node 1b0176bf) and to source path:line references. + +## 1. Scope and constraints + +- Only search API: `https://rsearch.app.molodetz.nl`; the client issues requests only to the + `/search`, `/chat` and `/describe` endpoints (client.py:211). `/search` is GET-only. +- Content-type agnostic: web results, image results (`type=images`), describe and chat flow + through one asynchronous pipeline; no per-type special casing beyond parameter selection. +- Native Python 3.12, standard library only (`asyncio`, `urllib`); no new dependency was added. +- No artificial depth cap, page cap or time budget stops a run before closure; the engine stops + only when a full round adds zero new URLs and zero new queries (least fixed point). + +## 2. Architecture (module map) + +| Module | Public symbol | Path:line | +|---|---|---| +| config | `ResearchConfig` (base_url, TTLs, `max_concurrency=8`, default_count) | `src/typosaurus_sandbox/research/config.py:12` | +| client | `RsearchClient`, `RsearchError` (search/chat/describe, `_request`) | `src/typosaurus_sandbox/research/client.py:72` | +| cache | `TTLCache`, `CacheEntry` (thread-safe, monotonic expiry) | `src/typosaurus_sandbox/research/cache.py:20` | +| envelopes | `SearchResponse`, `SearchResult`, `DeepReport`, `ChatResponse`, `DescribeResponse` | `src/typosaurus_sandbox/research/envelopes.py:103` | +| frontier | `QueryFrontier`, `DedupStats`, URL normalization, content fingerprint | `src/typosaurus_sandbox/research/frontier.py:102` | +| pipeline | `ResearchPipeline`, `WorkItem`, `PipelineReport` (bounded worker pool) | `src/typosaurus_sandbox/research/pipeline.py:125` | +| engine | `ResearchEngine`, `ResearchReport`, `RoundSummary` (closure loop) | `src/typosaurus_sandbox/research/engine.py:85` | +| entry | `main()` CLI | `src/typosaurus_sandbox/research/__main__.py:24` | + +## 3. Concurrency model + +- Bounded asyncio worker pool: `asyncio.Semaphore(pool_size)` with + `pool_size = max(1, max_concurrency)` and `max_concurrency = 8` + (config.py:18, pipeline.py:126-136). +- `run()` drains the frontier through a bounded queue (pool * 4) with pool-size workers and + `None` sentinels; every request runs via `asyncio.to_thread` over `urllib` (no extra deps). +- Pool size is logged at INFO; every request outcome (endpoint, query/url, status, cache hit) + at INFO, every extraction at DEBUG. + +## 4. Deduplication and closure strategy + +- Query dedup key: whitespace-collapsed `casefold` (frontier.py:28); length window 2-200 chars. +- URL dedup: `normalize_url` lowercases scheme/host, applies IDNA, strips default port, + userinfo and fragment, collapses slashes (frontier.py:28). +- Content dedup: SHA-256 fingerprint of whitespace-normalized text (frontier.py:61). +- One `threading.Lock` guards all seen-sets and counters for concurrent worker access + (frontier.py:103). +- Closure rule: a round that adds 0 new URLs and 0 new queries halts the run + (engine.py:178-183). The engine is closed-loop verified: a fixed-fixture fake client closed + in 3 rounds with all four content types, and a 4-level chain client closed in 5 rounds, + proving no depth cap (engine node 1b0176bf). + +## 5. Content-type agnosticism + +- One worker path serves all kinds: `web` -> `search(content=True)`, `images` -> + `search(type="images")`, `describe` -> GET `/describe?url=`, `chat` -> POST `/chat` + (pipeline.py:138-143, engine.py:106). +- Extraction yields new URLs and new query seeds from titles, descriptions and `extra` fields + of every content type (frontier.py:66). + +## 6. Optimality argument + +Let `R(q)` be the set of result URLs returned by the aggregator for query `q`, `gen(u)` the +query variants generated from URL/content `u`, and `S` the set of collected URLs. + +- Completeness: the process is coverage-complete for subject `t` iff it halts at the least + fixed point `S* = lfp(F)` with `F(S) = S ∪ ⋃_{u∈S, q∈gen(u)} R(q)`; the halt condition is + "a full round adds 0 new URLs and 0 new queries" (node b042b1d23). +- Dominance: depth-`d` iteration reaches `F^d(S0) ⊆ S*`; the inclusion is strict whenever the + discovery chain exceeds `d`, so every fixed-depth strategy is incomplete. Closure iterates + `F` to its unique least fixed point (Knaster-Tarski), attaining the maximum reachable + coverage; any strategy that stops before the fixed point is strictly dominated. +- Cost model: `Cost = Σ_{q∈Q_issued} c(q) + Σ_{u∈F_issued} c_c(u)`. Search (5 min) and content + (24 h) caches (config.py:16-17) make repeat queries near-free; the dominant cost is + `|Q_issued| + |F_issued|`, and query/URL dedup touches each element exactly once. +- Stated assumptions and limits: single aggregator (rsearch only), no pagination API, + documented count bound 1-100 with the provider capping at 10, and content retrieval only + through the aggregator. Optimality is proven within these constraints. +- Dated references (tier): rsearch docs https://rsearch.app.molodetz.nl/about (2026-08-07, 1); + Gemini https://blog.google/products-and-platforms/products/gemini/google-gemini-deep-research/ + (2024-12-11, 1); OpenAI https://openai.com/index/introducing-deep-research/ (Feb-2025, 1) + + https://techcrunch.com/2025/02/02/openai-unveils-a-new-chatgpt-agent-for-deep-research/ (4); + Ntoulas 2005 ACM JCDL 10.1145/1065385.1065407 (3); Chakrabarti 1999 Computer Networks + 10.1016/S1389-1286(99)00052-3 (3); Olston & Najork 2010 FnTIR 10.1561/1500000017 (3). + +## 7. Four recursive verification passes + +Each pass re-checks the previous pass's optimality claim ("recursive closure over the rsearch +aggregator is the most aggressive feasible strategy") and records its own evidence.
