# OpenRouter 58-label verification report

Decision: REJECT / DO NOT MERGE. Canonical label files were not mutated.

## Check 1 - provenance

Source tier is Tier 1 authoritative for all rows: Arctander, Perfume and Flavor Chemicals, local monograph extract. Parsed-from-source here means the stored source_text_excerpt states the character and the matched token(s) occur in that excerpt.

Accepted proposed rows reviewed: 58
Parsed-from-source with Tier-1 excerpt and matched tokens: 58
Model-proposed with no Tier-1 source support: 0

Note: CAS 141-14-0 has an evidence_quote spelling normalized as `Rose-Muguet`, while the OCR excerpt reads `Rose-M uguet`; the matched token `Rose` is still present in the stored Tier-1 excerpt, so it is counted parsed-from-source, not manufactured.

| 100-86-7 | DIMETHYL | H | 1 authoritative | Warm-herbaceous-floral, slightly animal odor, reminiscent of Lilac and Eldcrflowers with undertones of fresh cut wood. | herbaceous | parsed-from-source |
| 10031-96-6 | EUGENYL | W | 1 authoritative | Warm-woody, somewhat dry odor with a remote resemblance to Orris and a fresh-spicy, slightly green undertone. | Warm-woody | parsed-from-source |
| 101-81-5 | DIPHENYL | G | 1 authoritative | More pleasant and less “metallic”. Harsh Geranium-leaf, Orange-blossom type odor. However, its odor type limits its application to rather few fragrana types. | Geranium-leaf | parsed-from-source |
| 101-84-8 | DIPHENYL | R | 1 authoritative | Harsh floral-green, metallic Geranium type odor. The crystals appear to emit a much milder odor than the liquid material, and it is only in actual use that one can truly estimate and evaluate the strength of this material, often underestimated by the inexperienced perfumer. | Geranium | parsed-from-source |
| 101-97-3 | ETHYL | P | 1 authoritative | In combination. Powerful, sweet, Honey-like, slightly animal and quite pcrsistant odor with a fruity undertone reminiscent of Apricot. Clover, Oriental bases and numerous types of ““waxy”’odor. | Honey-like | parsed-from-source |
| 102-20-5 | PHENYLETHYL | Q | 1 authoritative | Heavy and very sweet, extremely tenacious, floral-balsamic odor which is sometimes described as “musky” (perhaps by observers who detect no special odor in the material), or “honey-like” (especially if it has surplus of Phenylacetic acid). | floral-balsamic | parsed-from-source |
| 103-45-7 | PHENYLETHYL | R | 1 authoritative | Very sweet, rosy-fruity, honey-like odor of moderate to poor tenacity. Variations in the odor of this material will naturally follow the pattern of the parent alcohol in which sharper, more pungent notes are typical of the commercial grades, while warm, deep-rosy notes with balsamic softness are typical of the highly refined grades. | rosy-fruity | parsed-from-source |
| 103-54-8 | CINNAMYL | Q | 1 authoritative | The spicy note has a tendency of. Very slightly soluble in water, soluble in alcohol and oils, Sweet, mild-balsamic and slightly floralfruity odor. | mild-balsamic | parsed-from-source |
| 103-82-2 | PHENYLACETIC | P | 1 authoritative | Sweet, animal-honey-like odor of extraordinary tenacity. In aqueous dilution the . Tiny crystal scales of the acid will emanate a very perceptible odor virtually through several decades if left in the open (e. | honey | parsed-from-source |
| 103-95-7 | CYCLAMEN | G | 1 authoritative | Diffusive and powerful floral-green floralstem like odor with pronounced vegetable, Cucumber-Melon-like notes. Overall resembling the odor of Lindenblossom. It is important that the stabilizer does not contribute to the odor of the aldehyde. | floral-green | parsed-from-source |
| 104-21-2 | ANISYL | F | 1 authoritative | Mild fruity-floral, slightly balsamic-vani]ialike odor in the Plum and Lilac type, also reminiscent of certain types of Cherry. | fruity | parsed-from-source |
| 104-62-1 | PHENYLETHYL | G | 1 authoritative | Powerful, green-herbaceous, rosy odor with some similarity to Chrysanthemum, Hyacinth and Watercress foliage. If traces of water or formic acid were present from the beginning, the material will not only show pungent and unpleasant odor, but it will deteriorate rapidly and increase further in acidity. However, a properly made ester, kept dry and cool, will keep excellently on the perfumer’s shelf, and its odor remains warm, green-herbaceous and floral. But their warm, dryfoliage type floral odor | green, foliage | parsed-from-source |
| 10482-77-6 | CITRONELLYL | R | 1 authoritative | Very mild rosy, somewhat dry-woody odor of considerable tenacity, but of low odor value, overall not too interesting. | rosy | parsed-from-source |
| 105-13-5 | ANISYL | V | 1 authoritative | Mild-floral, very sweet odor, reminiscent of Lilac and Vanilla with a faint, delicate, balsamic background. | very sweet, Vanilla | parsed-from-source |

| 106-21-8 | DIMETHYL | A | 1 authoritative | Waxy, dry-rosy odor. The description of this chemical has changed considerably over the past decade or so, because Dimethyl octanol was never commercially available in a state of purity that couId justify any &m odor description. The typical waxy odor, the dry undertones, are more pronounced in purer grades. | Waxy, typical waxy odor | parsed-from-source |
| 106-29-6 | GERANYL | F | 1 authoritative | Sweet, deep, fruity . Sweet, rather heavy, fruity odor reminiscent of Apples, with undertones of red Roses, slightly fatty-oily, but overall very pleasant. Needless to say that traces of free acid are detrimental to this odor picture. | fruity, Apples | parsed-from-source |
| 110-44-1 | SORBIC | Z | 1 authoritative | Pure Sorbic acid is practically odorless, but I commercial grade material may have a slight, peculiar odor, varying according to the method of synthesis used. | practically odorless | parsed-from-source |
| 112-17-4 | DECYL | F | 1 authoritative | Sweet fatty-fruity odor of Pineapple-Orange-like character, and rosy waxy undertones. | fruity, Pineapple | parsed-from-source |
| 115-95-7 | LINALYL | F | 1 authoritative | Sweet, floral-fruity odor recalling Bergamot and Pear.

| 119-36-8 | METHYL | F | 1 authoritative | Warm, sweet, rooty-fruity odor of moderate to poor tenacity. Pungent-sweet, fruity-rooty odor with burning sensation at high concentration. As a result of the subconscious reaction in people who are regular users of candy, flavored with Methylsalicylate, or dentifrice etc., the comment “minty” is often used for description of the flavor or odor of this ester. The most reliable judges for odor description are those who are not users of the item as a flavor. ln fact, the title material is a typica | rooty-fruity, fruity-rooty | parsed-from-source |
| 122-40-7 | AMYL | H | 1 authoritative | ACA is very susceptible. Very mild oily -herbaceous and somewhat floral odor, reminiscent of many types of natural flowers, but mostly of Jasmin, Gardenia and Tuberose. There is a marked difference in odor quality and floral effect between “high-grade” Amyl cinnamic aldehyde and “’reguIar” or commercial (prime, etc.) grade. Lots from various producers also show considerable difference in odor quality. Old or oxidized ACA has objectionable, rancidfatty odor. Lower grades of ACA may show by-odor o | herbaceous | parsed-from-source |
| 126-64-7 | LINALYL | F | 1 authoritative | Balsamic-floral, Bergamot-fruity odor of good tenacity. The odor varies considerably according to the method of production of this ester.

| 94-47-3 | PHENYLETHYL | Q | 1 authoritative | Very faint floral-balsamic odor reminiscent of dry Rose leaves and petals with a soft, honey-like undertone and excellent tenacity. The odor of this ester may not impress the observer on the first encounter, but in use it displays very attractive effects, other than the fixative effect. | floral-balsamic | parsed-from-source |
| SMILES:C#CCO | PROPARGYL | G | 1 authoritative | 1) as a by-product. Powerful and very diffusive, but rather pleasant, foliage-green, Geranium-leaf-like odor of poor tenacity. This alcohol is briefly mentioned because it is often included in perfume chemical literature, and one could have the impression that the material is useful and harmless for such purpose, It has been suggested as a “Geranium-green” fragrance chemical, but the author finds that we are very well stocked up with safer and better fragrance chemicals of that odor type. | foliage-green, Geranium-leaf-like | parsed-from-source |

| SMILES:CCCCC1CCC(=O)O1 | OCTANOLIDE-1 | H | 1 authoritative | Sweet-herbaceous Coconut-like odor with an oily Tonka-bean-like undertone. Very sweet . The odor of this, chemical is described in various literature as “Caraway-like Cumin” (86-28) and (31-173) “Peach” (86-105) but the author disagrees strongly, assuming that a mistake must be responsible for those descriptions. | Sweet-herbaceous | parsed-from-source |

| SMILES:COC(=O)c1ccccc1O | METHYL | F | 1 authoritative | Warm, sweet, rooty-fruity odor of moderate to poor tenacity. Pungent-sweet, fruity-rooty odor with burning sensation at high concentration. As a result of the subconscious reaction in people who are regular users of candy, flavored with Methylsalicylate, or dentifrice etc., the comment “minty” is often used for description of the flavor or odor of this ester.

Maurer (103-298) that the common description “pleasant floral New-Mown-Hay odor” is not only misleading, but also very incomplete. Even if the odor would be generally described as “pleasant and floral”, one should avoid phrases which almost imply or encourage a use of a hazardous material.

## Check 3 - D1 substantivity reopen

D1 reopen ran. Finished artifact: `artifacts/three_diagnostics_v8/diagnostic1_substantivity_integrity_finished_v8.json`.
Wild cause counts: `{"form-mismatch": 2, "genuine-source-disagreement": 47, "join-error": 8}`
Phase 1 scaffold intersection among 47 genuine disagreements: yes, 10 rows: 106-29-6 (Geranyl butyrate), 112-14-1 (Octyl acetate), 118-58-1 (Benzyl salicylate), 141-78-6 (Ethyl acetate), 141-97-9 (Ethyl acetoacetate), 68127-65-1 (Rhodinol), 8000-29-1 (Citronella, Ceylon), 8000-41-7 (Terpineol), 8008-45-5 (Nutmeg), 8014-09-3 (Patchouli)
Noise floor: no explicit target-noise/model-ceiling scalar is recorded in the D1 finished artifact. Stored proxy: measured-vs-auxiliary-tier agreement is 75/144 = 0.5208333333, disagreement 69/144 = 0.4791666667; after reopen, 47 are genuine source/construct disagreements, not measured-target join errors.
Saved Phase 1 structure model: R2 0.3990232662101132, Spearman 0.6633801733693918; baseline: R2 0.24057748815493107, Spearman 0.6130893034049266.
Handling policy: Do not fold disagreeing auxiliary tiers as substantivity supervision. Only near-boundary-consistent rows, and future join-corrected rows if any, may be folded with provenance poucher-tier; poucher-measured remains uncontaminated.
Verdict: measured 170 stands; Phase 1 conclusion survives; no recompute was needed because wild cases were not mostly measured-side join errors.
