feat(#262): cross-paper contradiction inventory — structured enumeration in synthesis layer (#373) ## What Adds a **structured cross-paper contradiction inventory** to `synthesis_agent` (Kong et al. 2026, L. Kong "Roadmap & User Guide", arXiv:2605.18661 §7.4.2 — multi-paper relational reasoning is a documented weakness of research-synthesis systems). The agent already narrative-discussed contradictions (Anti-Pattern 3, the Step 3 Contradiction Resolution procedure, the Contradictions & Resolutions table); this makes the *set of assessed paper-pairs* and the *unresolved / checked-clear* pairs **enumerable** for the scholar to confirm, instead of buried in prose. This is the cross-paper-relational sibling of #214 (within-review sub-claims) and #261 (figure fidelity) — all three enumerate before asserting "addressed." ## Approach — prose-layer only (mirrors #214 / #261, NOT #213) A new **Step 3b — Cross-Paper Tension Inventory** is **additive to** (not a replacement of) the existing Step 3 prose. The agent emits a `cross_paper_tensions[]` markdown block with a candidate-pair scoping heuristic and a mandatory Coverage Note. **No JSON Schema, no lint invariant, no gold fixture** — the producer (`synthesis_agent`) and the readers (the scholar plus the report/integrity LLM agents) all read prose; there is no deterministic downstream parser; and the judgment that matters ("genuine contradiction vs. conditional difference") is irreducibly semantic. Machine-validating the YAML shape would prove field presence, not contradiction fidelity — the same false-rigor scope call #261 made. ## Departures from the issue's literal acceptance (intentional, recorded) The issue acceptance read "schema adds `contradiction_pairs[]` block" + "calibration gold set accuracy ≥ 0.75". Both are deliberately not shipped as written, because following them literally would manufacture exactly the false rigor this repo rejected in #261: | Issue acceptance (literal) | What ships | Why | |---|---|---| | schema adds `contradiction_pairs[]` block | YAML-shaped **markdown** block in the existing Contradictions section | No deterministic machine consumer; schema = false rigor (#261 precedent) | | calibration gold set accuracy ≥ 0.75 (CI gate) | **No calibration artifact ships**; future/manual calibration recorded out-of-band, non-blocking | 20 LLM-judged pairs are too few / too nondeterministic across runs to be a hard gate | The field model is also corrected from the issue's non-MECE draft: the single `conflict_type` enum folded conflict *nature* with resolution *status* and referenced an `insufficient_overlap` value not in it. These are split into orthogonal axes — `pair_assessment` (conflict nature) × `resolution_status` (resolution state) — with a legality rule (a real tension never takes `not_applicable`; a non-tension takes only `not_applicable`), evidence pointers per side, and a degenerate-corpus rule (<2 papers / 0 candidate pairs → empty inventory, do not manufacture pairs). Full rationale: `docs/design/2026-06-08-262-cross-paper-contradiction-design.md`. ## Changes (4 files, prose/protocol + doc example only) - **`deep-research/agents/synthesis_agent.md`** — Step 3b inventory + candidate-pair scoping (recall-limited heuristic, inclusion-not-exclusion, mandatory Coverage Note) + Output Format Contradiction Section. Inherits the existing narrative-side discipline unchanged (advisory-only; emits `scholar_confirmation: pending`; no audit simulation; no frontmatter reads). - **`examples/contradiction_pairs_example.md`** — 6-paper worked example, 5 cases covering all four `pair_assessment` values and both resolution states of `conditional_difference`, with a load-bearing Coverage Note. - **`docs/design/2026-06-08-262-cross-paper-contradiction-design.md`** — design rationale + scope decision + departures. - **`CHANGELOG.md`** — `[Unreleased]` entry. ## Verification - Regression green: **2291 passed / 3 skipped / 1 xfailed** (no schema/lint/CI touched). - Reviewed across multiple independent passes to convergence on three axes (correctness/honesty, completeness/state-coverage, boundary); cell-legality verified consistent with orthogonality, example round-trips through all field rules, Coverage-Note arithmetic holds (6 papers ⇒ 15 pairs, 5 considered + 10 skipped). - No `#111` dependency (single boolean, per the issue's own correction).

# Example: `cross_paper_tensions[]` for a literature synthesis (#262)
A documentation example (not an executable fixture) showing how the `synthesis_agent` emits a `cross_paper_tensions[]` inventory in its Step 3b / Contradictions & Resolutions section, and how a scholar reads it. The corpus is a fictional review of *"remote-work productivity"*, with six papers.
Reference: `deep-research/agents/synthesis_agent.md` (Step 3b — Cross-Paper Tension Inventory). The inventory is a **prose contract** — there is no JSON Schema or lint behind it (mirroring the #214 / #261 prose-layer decision, not the #213 schema-layer one): the producer (`synthesis_agent`) and the readers (the scholar, plus the downstream report/integrity LLM agents) all read prose, so machine-validating the YAML shape would prove field presence, not contradiction fidelity.

**Coverage Note**: 6 papers in corpus (`alvarez2024`, `becker2023`, `okafor2025`, `dubois2024`, `nguyen2022`, `silva2025`); 5 candidate pairs considered (basis among the candidate-edge signals: shared RQ subtopic / shared construct / opposite finding direction / bibliographic coupling). This is a **scoped advisory scan, not complete pairwise contradiction detection** — the full corpus has 15 possible pairs; 10 were not exhaustively checked. In particular, `silva2025` (a manager-perception study) sits in a different topic neighborhood and was not paired against the productivity studies, and most `silva2025`/`nguyen2022` cross-pairs were not enumerated; a genuine tension among the unchecked pairs may exist and is **not claimed absent**. Bibliographic coupling was used as an inclusion signal only — low-coupling cross-camp pairs were not excluded on that basis. Scholar confirms each `resolution_pointer` and may flag additional cross-pairs.

## How a scholar (and the downstream report) reads each case
### Case 1 — `CP-001` (genuine contradiction, unresolved)
The two papers speak to the **same** outcome (individual task productivity under fully-remote work) and report **opposite directions** (+13% vs. 8%). The orthogonal axes carry distinct information: `pair_assessment: contradiction` says the conflict is real (not a definitional or scope artifact), while `resolution_status: flagged_unresolved` says the synthesis did **not** reconcile it. Because it is unresolved, there is **no `resolution_pointer`** — the agent must not invent one. The evidence pointers expose the most likely lever: Alvarez is within-subject (n=412), Becker is a cross-sectional survey (n=1,030); a scholar can see the design difference without re-reading both papers. `scholar_confirmation: pending` until the scholar decides whether to reconcile, present both, or weight by design.
### Case 2 — `CP-002` (conditional difference, resolved)
This is the axis-orthogonality payoff. Naively this looks like another contradiction (gain vs. loss), but `pair_assessment: conditional_difference` records that the divergence resolves on a moderator (coordination intensity) — Okafor's loss is for coordination-heavy roles, which is compatible with Alvarez's net gain. `resolution_status: resolved_in_synthesis` + a **required** `resolution_pointer` send the scholar to the exact paragraph where the synthesis explains the moderator. Had the issue's original single `conflict_type` enum been used, "conditional_difference" and "resolved" would have been forced into one value and the scholar could not tell *whether the difference was real but reconciled* from *whether it was never a real conflict*.
### Case 3 — `CP-003` (no material conflict)
A pair can be **listed without being a contradiction**. Becker and Dubois both find higher remote satisfaction at consistent magnitude. Recording it as `no_material_conflict` / `not_applicable` documents that the pair **was checked** (coverage), without manufacturing a tension. This mirrors #214's discipline that a checked-but-clear position is not opposition.
### Case 4 — `CP-004` (insufficient overlap)
The topics touch ("remote work") but the **evidence does not meet**: Okafor reports productivity, Dubois reports only satisfaction. `insufficient_overlap` records that the pair was considered and set aside because there is no shared measured construct to contradict — distinct from `no_material_conflict` (where they *do* measure the same thing and agree). Without this value the agent would be pushed to force a verdict on a non-comparison.
### Case 5 — `CP-005` (conditional difference, **un**resolved)
The third legal pairing on the orthogonal axes. Like CP-002 the divergence is a `conditional_difference` (schedule type — remote vs. hybrid — is the apparent moderator, not a true contradiction), but unlike CP-002 the synthesis **noticed it without yet reconciling it**: `resolution_status: flagged_unresolved`, so there is **no `resolution_pointer`** (omitted, exactly as the field rule requires for non-resolved status). CP-002 (`conditional_difference` + `resolved_in_synthesis`) and CP-005 (`conditional_difference` + `flagged_unresolved`) together show that the resolution axis moves independently of the assessment axis — the same conflict nature can be resolved or still open.
### The Coverage Note is load-bearing
The note is not boilerplate — it is the honesty mechanism that makes the recall limitation acceptable. It states the denominator (15 possible pairs), what was skipped (10), and names the paper in another neighborhood that was **not** paired. This is why the inventory may ship as a scoped scan: it never says "all contradictions addressed." Remove the note and the same block would be an overclaim.

## Cross-reference
- **#214** — sub-claim inventory before consensus in editorial synthesis (within-review version of "enumerate before asserting addressed"). #262 mirrors its prose-layer scope decision (no schema/lint/fixture).
- **#261** — figure/table fidelity trace (the figure version of the same enumerate-before-assert discipline), also prose-layer.
- **#213** — claim-audit sub-claim decomposition; got schema+lint only because it has a deterministic machine consumer. #262 does not, so it stays prose.
- **`devils_advocate_agent`** — stress-tests a single argument adversarially; it does **not** enumerate pairwise paper conflicts. Different scope; untouched.
- **Kong et al. (2026) §7.4.2** (L. Kong, "Roadmap & User Guide", arXiv:2605.18661) — the originating finding: research-synthesis systems summarize individual papers well but still struggle with multi-paper relational reasoning and cross-paper contradictions.
