Primary: Mark Twain
Confidence: high

Summary: The target document is almost certainly an excerpt from Mark Twain's 'The Innocents Abroad,' the same work represented in the candidate sample. The evidence is overwhelming: the target continues the same transatlantic excursion narrative to the Azores established in the candidate sample, and reproduces Twain's defining stylistic signatures—colloquial American vernacular in dialogue, comic character sketches of naive travelers, long accumulative sentences with bathetic deflation, nautical idiom used humorously, and a first-person travelogue voice that balances descriptive energy with deadpan humor. No other candidate comes close to matching these features. The primary caveat is that the candidate sample and target are drawn from the same book, making this attribution essentially a content-matching exercise as much as a purely stylometric one; however, the purely stylistic markers independently corroborate Twain as author.

VERDICT: ✔ MATCHES EXPECTED (expected Mark Twain)

CASE: T-002 — Poe (Tell-Tale Heart)
Note: The Tell-Tale Heart — different story than the Poe candidate sample (Fall of the House of Usher).

  Mark Twain             p=0.020
  Ralph Waldo Emerson    p=0.010

Primary: Edgar Allan Poe
Confidence: high

Summary: The target document is almost certainly 'The Tell-Tale Heart' by Edgar Allan Poe, exhibiting his most distinctive stylistic fingerprints: em-dash-driven syntactic fragmentation, obsessive lexical repetition, an unreliable first-person narrator explicitly defending his sanity, gothic psychological vocabulary, and percussive rhetorical questions addressed directly to the reader. These features align with overwhelming specificity to the provided Poe sample and are absent from all other candidates. The remaining four candidates—James, Thoreau, Twain, and Emerson—share no meaningful cluster of features with the target. The probability assigned to Poe reflects near-certainty given the density and specificity of matching stylistic markers.

VERDICT: ✔ MATCHES EXPECTED (expected Edgar Allan Poe)

========================================================================
CASE: T-003 — Emerson (Friendship essay)
Note: From the essay 'Friendship' — different essay than candidate sample (Self-Reliance).
Target word count: 600
Expected: Ralph Waldo Emerson
Calling analyzer...

→ 36.0s · 6324 in / 1897 out tokens

Ranked:
  Ralph Waldo Emerson    p=0.880
  Henry David Thoreau    p=0.070
  Henry James            p=0.030
  Mark Twain             p=0.010
  Edgar Allan Poe        p=0.010

Primary: Ralph Waldo Emerson
Confidence: high

Summary: The target document is almost certainly an essay by Ralph Waldo Emerson, most likely from 'Friendship' or a closely related essay in the Essays: First Series (1841). The convergence of evidence is strong: identical rhetorical devices (aphoristic short sentences, series of rhetorical questions, abstract-to-concrete illustration), shared Transcendentalist thematic concerns (the soul, affection, self-reliance, the transformative power of love), matching diction ('soul,' 'virtue,' 'eternity,' 'fine ether'), and identical punctuation conventions (em-dash mid-clause). No other candidate comes close to matching this profile. The archaic word 'Maugre' and phrases like 'proceeding eternity' and 'inward irradiations' are characteristic of Emerson's elevated essay register. Confidence is high given the substantial sample sizes and the specificity of the convergent features.
