…support (US1, FR-001/010, #107) Phase 2 substrate for the librarian agent — single canonical literature-search-and-citation-verification implementation that will replace three duplicates (lit_search + reference_validator's primary-source check + citation_resolver Stage-1) per Constitution Principle I. New sub-package src/llmxive/librarian/ (6 modules): - search.py — Semantic Scholar Graph API + arXiv API clients with rate-limiting (token bucket: 2/sec replenish, 5 burst for SS; 3-sec inter-call sleep for arXiv). Q1. - verify.py — canonical 3-check verification helper (URL resolves + title-token-overlap >=0.7 + summary-grounded >=0.5). Replaces duplicates in lit_search, reference_validator, and citation_resolver. - pdf_sample.py — >=10% PDF sample audit (Q2). Random sample; pypdf text extraction; graceful paywall/corrupt-pdf handling. - cache.py — sha256-keyed disk cache at state/librarian-cache/<key>.json (FR-011). TTLs: 30d arxiv / 7d http_head / 90d doi_bib. Cache invalidation on prompt-version bump. - expand.py — multi-step expansion (Q3): LLM brainstorm of 10-20 alt terms ranked by relevance + iterate until target_n verified accumulated OR list exhausted (cap 20). - search_trail.py — idempotent ## Search trail subsection writer for caller's idea/<slug>.md (FR-005, F1 fix from /speckit-analyze). New agent class src/llmxive/agents/librarian.py: - LibrarianAgent.invoke() — full pipeline orchestration (cache -> search -> verify -> maybe expand -> PDF sample -> cache write -> write search trail). Tool-style; doesn't advance project state. - LibrarianResult dataclass + to_dict() per contracts/librarian-json-output.md. Registry entry in agents/registry.yaml: librarian, prompt v1.0.0, qwen.qwen3.5-122b default, 600s wall-clock budget per Q4. Prompt at agents/prompts/librarian.md v1.0.0: expansion-brainstorm prompt section. Numbered-list output format; 10-20 ranked alternatives. Credentials support: src/llmxive/credentials.py refactored to merge keys instead of overwriting; new save_semantic_scholar_key() + load_semantic_scholar_key() functions plus SEMANTIC_SCHOLAR_KEY_NAME constant. Backward-compatible with all existing Dartmouth-key callers; verified by 7 new tests at tests/phase2/test_credentials_semantic_scholar.py. pyproject.toml: pypdf>=4 added (the only new dep) for the >=10% PDF sample audit. spec.md/plan.md/research.md/tasks.md updated to reference the SS API key (Decision 6 / FR-001 / T001+T001a). Substrate quirk documented in research.md: free unauthenticated SS tier returns 429 on the first search call, requiring authenticated key. Tests: 30/30 pass (15 spec-003 + 8 spec-004 + 7 new spec-005). No regression. US1 unit-test modules (T013-T017) blocked on SS API key approval; they will land in a follow-up commit once the key arrives. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
…(T013-T019, FR-001 SC-001/002, #107) Implements US1 (P1, MVP) per spec 005: - tests/phase2/test_librarian_search.py: 11 real-API tests (Semantic Scholar Graph API + arXiv API). 6 require SEMANTIC_SCHOLAR_API_KEY; skip-marked. Token bucket + thread-safety + dedup all covered. - tests/phase2/test_librarian_verify.py: 11 tests of the canonical 3-check verification helper (URL resolves + title-token-overlap + summary-grounded). Includes a real Vaswani-paper integration test + Jaccard tokenization edge cases. - tests/phase2/test_librarian_cache.py: 14 tests (TTL, prompt-version invalidation, deterministic-hit-on-same-state per SC-012, normalize_term edge cases). All real disk via tmp_path. - tests/phase2/test_librarian_pdf_sample.py: 14 tests including a real Vaswani PDF download + pypdf extraction. Sample-size formula, annotate_with_pdf_sample, paywall-handling all verified. T017 manual smoke: LibrarianAgent.invoke() end-to-end on "attention is all you need transformers" returned 20 verified citations in 11s with PDF samples + correct cache_status. Bug found + fixed: verify._fetch_title_and_abstract was returning the candidate's own claimed_title/claimed_abstract for the title-overlap check, making it a tautological self-comparison. Real impl now re-fetches title + abstract from arXiv API for arXiv candidates (DOI candidates trust the SS Graph API's already-canonical metadata). test_title_mismatch_fails caught this; fix verified by all tests passing. Total: 80/80 tests pass (23 spec-003+004 + 7 credentials + 50 new librarian). No regression. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
… (T020-T026, FR-004/005, SC-003, #107) Implements US2 (P1) per spec 005: - tests/phase2/test_librarian_expand.py: 15 tests covering the multi-step expansion module. 7 term-parser tests (numbered list, bullet list, original-term filter, header-skip, case-insensitive dedup, punctuation-only line filter, empty input). 2 real-LLM expand_terms tests (skip-marked when DARTMOUTH_CHAT_API_KEY missing). 6 iterate_until_target tests covering target-reached termination, per-term hit-count tracking, exhausted outcome on bogus terms, cross-term dedup, no-SS-client fallback, and the 20-term hard cap. - tests/phase2/test_search_trail.py: 9 tests for the idempotent Search trail subsection writer. Covers append-to-end, replace- existing (idempotency), all 4 frontmatter lines, search-terms table structure, numbered citation list with PDF-flag rendering (Yes/No/ Inaccessible), zero-citation placeholder, missing-file fail-fast, and the strip-existing helper's correctness around adjacent sections. Total: 104/104 tests pass (23 spec-003+004 + 7 credentials + 50 librarian core + 24 US2). 2 minutes runtime (real LLM + real APIs; no mocks).

…s (T027-T031a, FR-012, SC-001/002/003/007, #107) Implements US4 (P1) per spec 005: - tests/phase2/test_librarian_cross_domain.py: 8 parametrized tests invoking the librarian on the most-recently-brainstormed project in each default field (biology, chemistry, computer science, materials science, neuroscience, physics, psychology, statistics). Each invocation makes real Semantic Scholar + arXiv API calls; uses a module-scoped shared ArxivClient so its rate-limiting state persists across the 8 fields (prevents the burst-load 429 cascade). Per-field CrossDomainTestRow record written to tempdir for the diagnostic report's § 4 table. Cross-domain results (8/8 PASS): biology: success / 10 verified chemistry: success / 8 verified computer science: success_after_expansion / 10 verified materials science: success / 10 verified neuroscience: success_after_expansion / 7 verified physics: success_after_expansion / 10 verified psychology: success / 7 verified statistics: success_after_expansion / 10 verified Total verified: 72; SC-003 (≥3 fields fire expansion): 4/8 PASS. - tests/phase2/test_librarian_induced_failures.py: 4 tests covering SC-007 (Constitution Principle V — failure paths must be loud, not silent). Backend unreachable, invalid SS key, title mismatch, paywalled PDF. All produce structured failure records, not silent empty results. Two real bugs found + fixed: - ArxivClient.search() silently swallowed arxiv-library 429 HTTPError as zero results, masking burst-load rate-limiting. Now backs off 15s/30s/60s up to 3 attempts; surfaces final 429 via stderr diagnostic. Default min_interval_seconds bumped 3.0s → 5.0s for safety margin. - librarian.LibrarianAgent.invoke() returned an empty verified_citations list on cache hits because _result_from_dict was a stub. Re-hydrates VerifiedCitation + VerificationFailure dataclasses from the cached JSON; re-running with cache produces identical results to a fresh miss (SC-012 / FR-023 determinism). Total: 116/116 tests pass (23 spec-003+004 + 7 credentials + 50 librarian core + 24 US2 + 8 US4 + 4 induced-failure). 2 minutes runtime. No regression.

…on_resolver (Phase 6, FR-007/008/009/022, #107) Phase 6 rewirings consolidate three duplicate lit-search/verification implementations to satisfy Constitution Principle I: T032/T034 — agents/tools/lit_search.py: REWRITTEN as a soft- deprecation shim. The legacy ``Paper`` dataclass is preserved (so flesh_out's call site at idea_lifecycle.py:173 continues to work without modification). The ``lit_search()`` function body now delegates to ``LibrarianAgent.invoke()`` and adapts the librarian's ``VerifiedCitation`` records into the legacy ``Paper`` shape via ``_verified_citations_to_papers()``. Emits a DeprecationWarning when called. Verified end-to-end: lit_search('transformer attention') returns 9 Paper records via the librarian path. T033 — agents/tools/citation_fetcher.py: SOFT-DEPRECATED with banner pointing readers to the librarian. The reference_validator agent that consumes its ``FetchResult``/``VerificationStatus`` shape was NOT migrated in this PR; the adapter is non-trivial and was deferred per FR-014/15 to keep spec 005's blast radius contained. Banner explicitly forbids ADDING new callers (FR-022 enforced by T070a CI check, landing in Phase 10). T035 — tests/phase1/citation_resolver.py: SOFT-DEPRECATED with same pattern. Spec 003's tests + runbooks reference its specific record shapes; full migration deferred to follow-up. T036 regression: 116/116 tests pass; flesh_out's lit_search call still works (now via librarian); spec 003 + spec 004 test suites unaffected. The deferral pattern (banner + delegate where cheap, banner-only where the adapter is risky) is the standard "soft deprecation" approach and matches the strategy described in the spec-005 quickstart.md Step 3. The follow-up issue will complete the migration of citation_fetcher + citation_resolver to direct librarian calls; in the meantime, FR-022's CI guardrail prevents new duplicates from being introduced.

…progress for spec-005 librarian re-validation (manual; not a pipeline transition) (US3, #107)
…, T038-T048, #107) Both canonicals revalidate cleanly under librarian-backed lit search: - PROJ-261-evaluating-the-impact-of-code-duplicatio flesh_out_in_progress -> flesh_out_complete -> validated -> project_initialized Search trail: 5 verified citations (success_after_expansion) Validator: 4/4 sub-checks pass; verdict=validated Judgment: verified - PROJ-262-predicting-molecular-dipole-moments-with Same sequence; verdict=validated; Judgment: verified Aggregate verdict: PASS (US3 acceptance met). Bug fixes uncovered + fixed during T041 follow-up: 1. flesh_out's _persist was overwriting the librarian-written `## Search trail` subsection. Fixed by preserving the trail across the rewrite (idea_lifecycle.py). 2. librarian.invoke's cache-hit early-return path skipped the trail-write step. Fixed by hoisting trail-write above the return so cache hits + cache misses both populate the trail (librarian.py). 3. flesh_out was calling the soft-deprecated lit_search shim, which doesn't propagate idea_md_path. Replaced with a direct LibrarianAgent.invoke() call passing idea_md_path (FR-007). T047 orchestration test (3/3 pass): - test_persist_preserves_search_trail_subsection - test_search_trail_idempotent_overwrite - test_revalidation_results_yaml_shape Phase 2 regression: 88/88 pass (excl. cross-domain network tests).

14 tasks
The original verify_citation chain only compared the search backend's
claimed_title against its own re-fetched fetched_title — a self-
consistency check, not a topical-relevance check. Search hits that
shared only generic stop-tokens with the user's query (e.g.
"demographic", "lifestyle", "analysis") were "verified" despite being
completely off-topic.
Concrete bug example: gut-microbiome / cognitive-aging query returned
"Demographic Confounding Causes Extreme Instances of Lifestyle
Politics on Facebook" as the FIRST verified citation under v1.0.0.
Fix:
- Added Check 0 (topical relevance gate) at the top of verify_citation
- query_relevance_score = |salient_query_tokens ∩ candidate_tokens| / |salient_query_tokens|
- Threshold: 0.30 (≥30% of query's salient — non-stop-word, len≥3 — tokens
must appear in candidate's claimed title+abstract)
- Stop-word list filters tokens like "the/and/study/analysis/method/factor"
- Containment metric (not Jaccard) avoids penalizing the natural
length asymmetry of long queries vs. short titles
- Threaded `query` through _verify_each (librarian.py) + iterate_until_target
(expand.py); each expanded term is its own effective query
- Added VerificationLog.query_relevance_score field
- Added VerificationFailure.reason="query_irrelevant"
- Bumped librarian prompt_version 1.0.0 -> 1.1.0 (cache invalidation;
verification semantics changed)
Re-runs after fix:
- Phase 2 regression: 95/95 PASS (added 6 relevance tests)
- US4 cross-domain: 8/8 PASS, 58 verified citations (vs 72 under v1.0.0
— gate filtered 14 false positives), all first-verified-citation now
genuinely on-topic per manual audit
- PROJ-261 re-validation: validated (4/4), 7 verified citations on
LLM-code-understanding topics ("SIMCOPILOT", "Evaluating Code
Generation of LLMs", etc.) — fully on-topic
- PROJ-262 re-validation: validated (4/4), 9 verified citations on
GNN-dipole-moment topics ("Q-DFTNet", "PhysNet", "MolNet_Equi", etc.)
— fully on-topic
- One field (biology) overran 600s soft budget by 24s; accepted as
P5-D09 (LOW, soft target only)
Updated: revalidation-results.yaml, carry-forward.yaml, diagnostic
report (Sections 4/5/6/7), librarian.py, verify.py, expand.py,
registry.yaml. Wiped stale v1.0.0 cache.

Fix-up commit: P5-D08 (CRITICAL) — topical-relevance gate addedAfter your spot-check of the cross-domain results, I confirmed the original verification was structurally broken: it only compared each search backend's claimed_title against its own re-fetched fetched_title (a self-consistency check), so SS+arXiv hits sharing only generic stop-tokens with the user's query were "verified" despite being completely off-topic. Concrete bug: gut-microbiome / cognitive-aging query returned "Demographic Confounding Causes Extreme Instances of Lifestyle Politics on Facebook" as the FIRST verified citation under v1.0.0. Fix (commit 260ddd2):
Re-runs after fix:
One accepted soft caveat (P5-D09, LOW): biology overran the 600s soft budget by 24s. Budget is documented soft guidance, not enforced. Defect tally: 9 total — 8 fixed in-PR (1 CRITICAL, 3 HIGH, 4 MEDIUM/LOW); 1 accepted as soft guidance. Diagnostic report § 4 / § 5 / § 6 / § 7 updated. carry-forward.yaml + revalidation-results.yaml updated to record librarian_prompt_version: 1.1.0 + new verified counts. |
…CAL)
The token-overlap gate from P5-D08 caught gross stop-token false
positives (e.g. "Facebook politics" for gut-microbiome query) but is
**field-level**, not topic-level. Manual audit (per user pressure on
"how specific are the topically relevant papers?") revealed that
under v1.1.0:
- 5 of 8 cross-domain fields had field-adjacent first-verified
citations that didn't address the user's specific sub-question
(e.g. "GNN for social influence" admitted for a "GNN for dipole
moments" query because both share {graph, neural, network})
- PROJ-261 returned LLM-code-generation papers but none specifically
about *code-duplication's* effect
- PROJ-262 returned 9 GNN papers but several were unrelated GNN
applications
Fix: added LLM-based topical-relevance judge as Check 3.5 between
verification and PDF-sample. One LLM call per surviving candidate;
strict yes/no on "does this paper directly address the user's
specific question, not just the broad field?". Marginal-fallback
rule: if judge rejects ALL candidates, admit the rejected set with
`topically_marginal=True` flag in bibliographic_info — better to
surface near-relevant work labeled honestly than to be silent.
Initial v1.2.0 prompt was too strict (rejected animal-model
gut-microbiome studies as "non-human, non-observational"); retuned
v1.3.0 with explicit "lit-review-style" guidance allowing
same-mechanism evidence across populations/methodologies.
Re-runs after fix:
- Phase 2 regression: 104/104 PASS (added 9 judge tests, 7 parser +
2 real-LLM smoke verifying judge correctly says NO to "Social
Influence GNN" for a dipole-moment query and YES to PhysNet)
- US4 cross-domain: 8/8 PASS, 37 verified-citation total under
v1.3.0 (vs. 58 under v1.1.0 — judge filtered field-adjacent
candidates):
* 5/8 fields bullseye-on-topic (biology, chemistry, materials,
physics, psychology)
* 1/8 adjacent-relevant (neuroscience: brain network paper)
* 2/8 marginal-fallback (CS small-world+convergence, statistics
planned-vs-achieved-power) — narrow questions with no SS+arXiv
match; surfaced as labeled marginal evidence
- PROJ-261: judgment=verified; 7 marginal-fallback citations
(judge correctly notes no narrow match for code-duplication
effect; closest available LLM-code-evaluation papers labeled)
- PROJ-262: judgment=verified; 7 strict-topical citations
(Q-DFTNet, PhysNet, MolNet_Equi all bullseye on
GNN-dipole-moment prediction)
The marginal flag renders as "⚠️ topically marginal — admitted as
fallback when judge rejected all stricter matches" in the Search
trail subsection so downstream agents see honest provenance.
Wiped stale v1.0.0 + v1.1.0 caches. Bumped librarian
prompt_version 1.1.0 -> 1.2.0 -> 1.3.0.

Fix-up #2: P5-D10 (CRITICAL) — LLM-based topical-relevance judgeYou pushed back on the v1.1.0 fix: "how specific are the topically relevant papers? are they on the actual topic desired?" The honest answer was that the token-overlap gate was field-level, not topic-level. Manual audit confirmed:
Fix (commit d582a0a): Added Marginal-fallback rule: when the judge rejects ALL candidates, admit them back with Initial v1.2.0 prompt was too strict (rejected animal-model gut-microbiome studies as "non-human"); retuned v1.3.0 with explicit "lit-review-style" guidance. Re-runs after fix (3.5+ hours of real LLM/HTTP work):
The marginal flag renders in the Search trail as Defect tally: 10 total — 9 fixed in-PR (2 CRITICAL: P5-D08 + P5-D10; 3 HIGH; 4 MEDIUM/LOW); 1 LOW accepted-as-soft-guidance (P5-D09 budget). Bumped librarian prompt_version 1.1.0 → 1.2.0 → 1.3.0 with cache invalidation each step. The librarian now returns either bullseye-specific citations OR honestly-labeled marginal citations when SS+arXiv have no exact match — never silently topically-wrong results. |
…ICAL)
Manual lit-search audits on the 4 non-bullseye projects (launching 4
parallel scientist agents in response to user's pressure on citation
specificity) revealed that under v1.3.0 the librarian was missing
**substantial real on-topic literature** that exists in SS+arXiv:
- PROJ-350 statistics: missed Bakker 2020, Lakens 2022, Hardwicke
2023, Szucs 2017, Button 2013 (10 papers total)
- PROJ-336 neuroscience: missed Bonna 2021 rs-fMRI-in-deafness using
modularity+global-efficiency, Al Zoubi 2021 floatation-REST,
Pang 2023, Guerreiro 2021 (8 papers)
- PROJ-261 LLM-code-duplication: missed Allamanis 2019 deduplication
in code ML, Lee 2022 deduplication in LM training, Kandpal 2022
privacy/memorization (10 papers under "memorization/contamination/
deduplication" vocabulary)
- PROJ-262 GNN-dipole-moment: missed Gilmer 2017 MPNN-for-quantum-
chemistry (the foundational reference)
Three convergent retrieval failure modes:
Mode 1 — VOCABULARY MISMATCH: question's "code duplication" never
matches literature's "memorization/contamination/deduplication";
"statistical power" matches "intraocular lens power" instead.
Mode 2 — SENTENCE-SHAPED QUERIES: long natural-language questions
get bag-of-words-ified by SS/arXiv; signal diluted across
stop-words ("how", "change", "experimentally").
Mode 3 — SINGLE BROAD QUERY: multi-axis questions need multiple
targeted queries.
Fix:
- New module src/llmxive/librarian/query_extractor.py
- One LLM call per librarian invocation produces 5 short keyword
queries (2-6 tokens each) with synonym variants for divergent
vocabulary clusters
- System prompt explicitly demands at least one query use
canonical alt-vocabulary terms (e.g., "memorization" alongside
"code duplication")
- LibrarianAgent.invoke() runs all queries (extracted + raw term
as baseline) in parallel; unions candidates by primary_pointer;
feeds union into existing verify+judge+fallback pipeline
- 12 new tests (10 parser + 2 real-LLM smoke); both real-LLM tests
verify the extractor produces synonym variants for an actual
research question
Re-runs after fix:
- Phase 2 regression: 116/116 PASS
- US4 cross-domain: 8/8 PASS in 1h43min
* Specificity: 6/8 fields bullseye (vs 5/8 v1.3.0)
* 0/8 marginal-fallback used (vs 2/8 v1.3.0) — extractor surfaces
canonical-vocabulary papers judge accepts strictly
* Statistics now bullseye: first verified is "Brief Report: Post
Hoc / Observed / A Priori / Retrospective Power" (canonical
taxonomy paper v1.3.0 missed under "intraocular lens power"
contamination)
* Materials science: 10 grain-boundary-segregation thermodynamics
papers (vs 6 under v1.3.0)
* Biology: 8 gut-microbiome-cognition-aging papers
* 1/8 confirmed real lit gap (CS clustering-coefficient × loss-
convergence — narrow question, no paper exists at intersection)
- PROJ-262 v1.4.0: 10 strict-pass citations including foundational
Gilmer 2017 "Neural Message Passing for Quantum Chemistry"
(arXiv:1704.01212) that v1.3.0 missed entirely
- PROJ-261 v1.4.0: 16 marginal-fallback citations — extractor
DID surface "training data contamination code memorization" as
a query (6 hits) but the strict topical judge correctly notes
no candidate narrowly addresses the specific clone-density ×
perplexity correlation pattern; honest marginal labeling is
preferable to admitting field-adjacent work as bullseye
Cost: ~5x mean per-invocation duration (195s → 775s) due to parallel
multi-query approach + LLM extractor call. Several fields exceed the
600s soft target — accepted as the documented cost of the recall
improvement (P5-D09 budget remains soft-only).
Bumped librarian prompt_version 1.3.0 -> 1.4.0; wiped stale v1.3.0
cache.

Fix-up #3: P5-D11 (CRITICAL) — concept-decomposed query extractorYou pushed even deeper: "for the non-bullseye projects, manually search the literature to see what you can come up with — are there indeed no closely related papers, or are we missing something critical?" I launched 4 parallel scientist agents and they found substantial real on-topic literature the librarian was missing under v1.3.0:
Three convergent retrieval failure modes:
Fix (commit 2712d24): New module Re-runs (~3 hours of real LLM/HTTP work):
Cost: ~5x mean per-invocation duration (195s → 775s) due to parallel multi-query approach. Soft-budget overruns accepted as documented cost of the recall improvement. Defect tally: 11 total — 10 fixed in-PR (3 CRITICAL: P5-D08 + P5-D10 + P5-D11; 3 HIGH; 4 MEDIUM/LOW); 1 LOW accepted (P5-D09 budget). Bumped librarian prompt_version 1.3.0 → 1.4.0. |
…rical-population directive (HIGH)
Round-2 manual lit-search audit (4 parallel scientist agents,
user-driven repeat audit on the v1.4.0 non-bullseye projects)
revealed two residual systematic patterns:
1. JUDGE OVER-REJECTION: the strict topical judge was rejecting
papers that ARE the canonical lit-review references because
they use canonical alt-vocabulary or don't measure the user's
exact metric. Audit findings:
- PROJ-261: judge admitted 0/22 candidates including the
canonical "deduplication / memorization / contamination"
papers (Lee 2022, Matton 2024, Allamanis 2019)
- PROJ-350 stats: judge admitted only 2/12 from a candidate
set that included Bakker 2020, Lakens 2022, Hardwicke 2023
- PROJ-336 neuro: Pang 2023 + Guerreiro 2021 surfaced as
candidates but rejected for not explicitly computing
"modularity"
The "lean YES — adjacent evidence" guidance in v1.3.0/v1.4.0
wasn't strong enough to override the strict "narrowly addresses"
framing in the same prompt.
2. EXTRACTOR STILL REVIEW-STYLE NOT EMPIRICAL-POPULATION-STYLE:
v1.4.0 produced "sensory deprivation" queries when the
literature is indexed under "early deafness" / "Floatation-REST"
/ "congenital blindness"; produced "code duplication" without
bridging to "HumanEval MBPP dataset" (the canonical code-LLM
benchmark empirical population vocabulary).
Fix:
- Judge prompt (relevance_judge.py) rewritten with 6 explicit
ACCEPT categories (a-f):
(a) Same-mechanism evidence (cross-population, cross-method)
(b) Independent-or-dependent variable on the same domain
(c) Empirical baseline (e.g., Button 2013 power-distribution)
(d) Foundational methodology / canonical reference
(e.g., Gilmer 2017 MPNN for any GNN-property question)
(e) Empirical-population canonical study (e.g., rs-fMRI in
deaf adults for sensory-deprivation question)
(f) Cross-vocabulary alt-cluster (e.g., "deduplication" papers
for "code duplication" question)
With CRITICAL note: "a paper does NOT need to address the FULL
correlation in the user's question to count. Lit-review
references are individually partial."
- Extractor prompt (query_extractor.py) rewritten with 5 REQUIRED
VOCABULARY COVERAGE rules:
1. Alt-vocabulary (synonyms literature uses)
2. Empirical-population (e.g., HumanEval MBPP, QM9, IAT,
Floatation-REST) — REQUIRED if question references an
experimental population/paradigm
3. Sub-community canonical proxy (e.g., "homophily" for
"clustering coefficient in GNN")
4. Measured-outcome canonical evaluation framework
5. Causal-mechanism / theoretical-framing
Re-runs after fix:
- Phase 2 regression: 116/116 PASS (one transient arXiv 429 on
re-test passes)
- US4 cross-domain: 8/8 PASS in 2h25min, 44 strict-pass total,
0/8 marginal-fallback
- Concrete improvements over v1.4.0:
* statistics: now surfaces canonical "Brief Report Post Hoc /
Observed / A Priori / Retrospective Power" + ANOVA a-priori-
vs-post-hoc + pilot RCT sample-size simulation paper (vs
v1.4.0's 2 marginal)
* CS PROJ-353: 2 strict-pass (vs 1) — extractor now bridges to
homophily/contrastive cluster as audit predicted
* neuroscience: 4 strict-pass (vs 3) including cross-modal
plasticity in single-sided deafness
- Concrete extractor wins: "HumanEval MBPP dataset" (code-LLM
canonical empirical pop), "QM9 dataset graph neural network"
(chem canonical empirical pop), "Watts-Strogatz small-world
graphs" (sub-community canonical proxy for ML), "intrinsic
connectivity graph metrics" + "modularity global efficiency
fMRI" (neuro canonical proxies)
Lingering issues identified during manual audit:
- JUDGE NON-DETERMINISM: PROJ-261 single-query probe got 3
strict-pass (no marginal); a separate flesh_out re-validation
invocation on the same question got 0 strict / 9 marginal.
Same prompt + same question → different verdicts. This is
LLM temperature noise that prompt-only fixes can't fully solve.
Documented in revalidation-results.yaml + diagnostic § 6.
- EXTRACTOR FALLBACK BUG: materials science cross-domain run
showed the extractor returning only 1 query (the LLM call
failed silently → fallback path activated). Fortunately the
1 fallback query brought 20 hits and the judge accepted 6
bullseye papers, but this is a silent regression of fix-up #3.
Documented as future-issue.
- SOFT-BUDGET OVERRUNS: per-invocation duration grows further
under v1.5.0 (longer judge prompt, more permissive judge
admitting more candidates → more PDF samples). Several fields
exceed the 600s soft target. Cross-domain run took 2h25min
overall vs v1.4.0's 1h43min.
Both PROJ-261 + PROJ-262 re-validate `verified` under v1.5.0.
Bumped librarian prompt_version 1.4.0 -> 1.5.0; wiped stale v1.4.0
cache.

Fix-up #4: P5-D12 — judge ACCEPT categories + extractor empirical-population directiveYou pressed deeper after fix-up #3: "for the non-bullseye projects, manually search the literature again — are we missing something critical?" Round 2 of 4 parallel scientist agents found two residual systematic patterns under v1.4.0:
