When the profile model pairs a $53 blend with a $145 malt

Sources

• generate_cycle.py replay payload, artefact 2026-09-03-replay/compare-the-pair/johnnie-walker-black-label-12-year-old-blended-scotch-whisky-ba4131, grounded on vintage 2026-09-03.r, window as-of 2026-09-03.
• Johnnie Walker Black Label 12 Year Old Blended Scotch Whisky 700mL: shelf ticket $53 (claim / grounding.ref.price), not a member offer; at its own-history floor (percentile 0.0, quiet_discount, price variation present, 6 observations). Scotland, Blended, age 12.
• Lagavulin 16 Year Old Islay Single Malt Scotch Whisky 700mL: shelf ticket $145 (claim / grounding.cand.price), not a member offer; at its own-history floor (percentile 0.0, quiet_discount, price variation present, 6 observations). Scotland (Islay), Single Malt, age 16.
• Similarity: VSM profile cosine 0.9530, VSM rank 2; CE utility score 0.0466, CE rank 17 (candidate.pair, rank_diff -15).
• Pair combined-price series (grounding.pair_level.dates / pair_series.sums), 2026-08-05 → 2026-09-03: 214.85, 204.90, 209.90, 210.90, 206.90, 197.85. Today's $197.85 is the lowest of the six; the prior-five mean is $209.49. Reported as a plain observation.

Omissions

• Light form only: no CE 360° band, no cross-read CEARP, no Welch t-test on the two means. Ruled out here, not implied.
• Each leg carries 6 in-window observations; the 'at the floor' read rests on a six-week history and the post keeps it to a timing observation, never a movement or trend claim (CHANNEL.md §1).
• The pair-level sum test is the selection trigger; its p-value is not quoted. Six snapshots make it an ordinal gate, so the post treats "cheapest in the window" as an observation, not a significance claim.
• No bundle price is asserted as a recommendation; $197.85 is a literal sum of two live tickets.
• Two other compare-the-pair candidates cleared select() this cycle and were dropped: JW Black 700mL / JW Black 1L (shares this anchor — one anchor per batch, and reruns the same 'both at floor' shape), and Glenfiddich 15 / Glenfarclas 15 (cool-down — Glenfiddich 15 headlined 2026-08-27, Glenfarclas 15 the 2026-08-20 price raid).

Notes for reviewer

• Flagged: the pairing is a profile-model near-twin (VSM rank 2) but a value-model outlier (CE rank 17, rank_diff -15). Confirm the post reads as 'a cheap smoky blend and a benchmark Islay, both keenly priced this week', not 'these are the same whisky'.
• Flagged: this exact shape — a $53 blend against a $145 Islay malt, both at their own floor — is named in the compare-the-pair spec as one that once ran twice in a single cycle. It runs once here; the sibling JW Black candidate was dropped for that reason.
• Replay draft on rehearsal vintage 2026-09-03.r; may_publish: false and never flips in replay.

Format note

Compare the pair, automated light form. Two shelf tickets, each bottle's own-history position, and the pair's six-week combined-price series; no CE 360 bands, no cross-read CEARP, no Welch t-test on the two means (light form). Both prices shelf basis, neither a member offer. Both 700mL. Not a claim they are interchangeable: the profile model ranks them 2nd-closest (VSM), the value model 17th (CE), rank_diff -15 — a shared-character note with a keen combined price this week, not 'the same whisky, cheaper'.
