Do the classic craft texts agree that conflict is essential to drama, and which author says what (with candidate id, evidence id and pinned offset)?

Concordance (code_derived_inference, not an author's claim) over eight texts. Phillips (1914) is the clearest yes: 'In all drama there is struggle with an obstacle.' Baker (1919) says by Brunetiere's definition conflict is central but 'covers a large part of drama but not all of it', naming an inert-figure exception that rests only on audience emotion. Munsterberg (1916, Ch. VIII) and Lutz (1920, cartoon plots) state it in passing or inside a narrower scope. Archer's view reaches this batch only second-hand (not indispensable, but 'no obstacle, no drama' as practice). Aristotle (Poetics XIII-XV) and Esenwein and Leeds (Ch. XIV) have scoped negatives; Forster has no record. The authors do not mean the same thing by 'conflict': an opponent (Baker's quoted list), an obstacle of any kind (Phillips) or a clash between two figures (Lutz). Curator qualifications: Concordance reproduces. The three meanings of conflict are a useful split for agents: opponent, obstacle and clash between two. Archer is labelled 'relayed_only' (weaker form). His own statement is in the pinned Archer text at L823-827, the passage the worker re-found. He explicitly rejects conflict as indispensable to drama. Archer is therefore a direct source-statement counterposition to Phillips's strong form, not merely relayed. The disagreement runs Phillips (all drama) / Baker (large part, not all) / Archer (one element; error to make it indispensable). Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
