**The 20-model test supports a documentation and candidate-parts directory, with human review before publishing compatibility claims.** Public catalogs exposed useful part numbers and purchase listings, but no sampled relationship was confirmed for a specific cabinet serial number. Parts Town pages opened for 17 of the 20 models; one additional exact-model catalog was visible only through indexed results. Two model pages remain unverified. The sample also exposed a serious identity conflict inside the source CSV. Affiliate monetization remains unproven: a public program exists, but approval, selected-part offers through that program, and working tracked links were not established.

Checked **November 8, 2026**. Research used the subsequently supplied `export.csv`: **1,994 records, including 258 True Refrigeration records**. The original chat's `/mnt/data/export(1).csv` was unavailable, so byte-for-byte equivalence cannot be established. The supplied file's SHA-256 is `767886c07c161d504c478f0b9e66695fd815a121bbe7fcc335165884e0d378f8`. The companion source CSV preserves all 30 original columns for the selected rows, and the results CSV preserves exact model strings and ENERGY STAR IDs.

Selection was a **purposive stress test**, spanning reach-ins, display cabinets, bar equipment, undercounters and worktops, including `~TSL01` and `~SPEC3` versions. It was not random. Coverage percentages below describe these 20 models and should not be extrapolated to all 258 True records. No previous-chat claims were counted as verification.

Official manual-family links were found for all 20 models. A family title establishes a documentation lead; it does not establish exact-model or revision applicability. Several PDFs exceeded the research reader's size limit. T-23-HC and T-49-HC appeared on an indexed official manual cover, while the Spec Series manual was opened without independently finding the exact STA model. Each row below distinguishes an opened family document from a linked-only document. ([True manual library](https://www.truemfg.com/support/manuals/))

The table reports **observed distinct manufacturer part numbers per model**, as lower bounds across returned research snapshots. They are neither complete catalog counts nor counts of confirmed compatible or currently purchasable parts. Some pages were cached; stock labels are snapshot observations, with no checkout or physical inventory test. **Exact/opened** means the model designation was preserved and the page opened. **Alias/opened** means punctuation changed while the full suffix remained; this is a candidate association. **Indexed only** and **unverified** carry weaker evidence. All rows retain unverified serial fit and affiliate approval, including those with purchase listings.

Within this sample: **20/20 (100%)** had official manual-family links; **17/20 (85%)** had opened Parts Town model pages, including five punctuation-alias candidates; **18/20 (90%)** had an opened or indexed model catalog. These exposed **234 observed model-catalog/part-number associations involving 98 distinct part numbers**, including indexed-only STA evidence and alias candidates. Retrieval depth differed, so counts should not be used to compare catalog size. The GDM-05-HC-LD row has two indexed individual-part offers, excluded from catalog counts. **0/20** had cabinet-specific serial fit established, and **0/20** had a verified approved affiliate link. These denominators retain the quarantined source row for transparency.

**Compatibility conditions materially change the interpretation of a catalog match.** True's store says cabinet age can change available part options, and its expanded parts lookup requires the serial number and registration. The manufacturer also warns that HC and older refrigerant-system components are not automatically interchangeable. No physical unit serial numbers or authorized serial-lookup outputs were available for this test. ([True parts support](https://www.truemfg.com/support/parts/), [official store](https://shoptrueoemparts.truemfg.com/), [True FAQ](https://www.truemfg.com/support/frequently-asked-questions/))

A concrete example is gasket **810719**, visible in the T-23-HC and T-49-HC catalogs. A merchant-hosted compatibility PDF limits its use on those HC models to production **before August 26, 2017**. The same document includes plant, date and serial exceptions for legacy models. Thus, a visible model association cannot support an unconditional fit claim. The results CSV adds this restriction to the relevant sample rows. It does not transfer legacy-model serial cutoffs onto HC variants. ([810719 compatibility notes, pages 1 and 3](https://www.webstaurantstore.com/documents/pdf/compatibility/810719_compatibility_notes_101824.pdf))

True's own model collections provide further model-to-part evidence while demonstrating another dependency: FLM control **222591** and TUC-27-HC~SPEC3 control **234671** require model and serial information for programming. These are separate manufacturer catalog observations; they are not added to the Parts Town counts. ([FLM collection](https://shoptrueoemparts.truemfg.com/collections/flm-27-tsl01), [SPEC3 collection](https://shoptrueoemparts.truemfg.com/collections/tuc-27-hc-spec3))

**Quarantine the STA1R-1S-HC row before enrichment.** Source ID `2404388` says “Pass-through,” four solid doors and depth 36.13 inches; its certification identifier names `STA1RPT-2HS-1S-HC`. True's sheet covering STA1R-1S-HC instead describes a reach-in and depth 33.75 inches. The original row remains unchanged in the source deliverable. Its parts catalog is a match to the written model designation, not a resolution of this conflict. Separately, Parts Town's T-23F-HC page contains body copy naming T-23-HC; its heading/model field retain the freezer designation. Both issues argue for checking structured identities against supporting evidence. ([True Spec Series sheet](https://www.truemfg.com/wp-content/uploads/true-media/spec-sheets/STR1R-1S-HC.pdf), [STA catalog](https://www.partstown.com/m/true/sta1r-1s-hc), [T-23F-HC catalog](https://www.partstown.com/m/true/t-23f-hc))

Merchant purchase listings are useful, but **affiliate revenue has not been demonstrated**. Parts.Store's opened agreement, version September 15, 2026, requires approval and a US-bank payout capability; rates are account-specific. Its current referral window is **seven days**, superseding the earlier chat's 30-day figure. No selected True part listing on that affiliate merchant, user approval, or functioning tracked link was verified. No current public refrigeration affiliate program for Parts Town or True was confirmed in the bounded search; private arrangements remain unknown. ([Parts.Store agreement](https://parts.store/affiliate-agreement))

The practical recommendation is to proceed with a small reviewed directory offering original source specifications, official documentation links and clearly labeled candidate parts. Hold the conflicted source row for review, preserve suffixes, and require serial/date evidence before asserting fit. Treat unresolved fetches as unverified rather than absent. Before scaling merchant ingestion, establish an authorized feed or reuse arrangement: PartsPath advertises API integration for model, parts and ordering data, but public API access and permission to republish into an SEO directory were not verified. This proof of concept establishes observable enrichment opportunities; it does not establish search demand, automated collection reliability, licensing, or affiliate economics.
