Data accuracy: corrections, duplicates and dates (workstream)

[Seungpyo1007]

Purpose

Tracker for data accuracy: correcting existing values, merging duplicates, fixing dates and links. It is one of the workstreams split out of the #1 roadmap on 2026-09-27.

PRs that fix data (fix(data…), or label data + bug) link here with Closes #<this>. The tracker stays open.

Scope

• Cross-checks against Wikipedia and manufacturer spec pages (CPU, GPU, SoC, watch)
• Plausibility outliers (storage recorded as RAM, unit slips, impossible values)
• Duplicate or near-duplicate records (merging while keeping the better record)
• Placeholder dates (YYYY-01-01) and placeholder SoC links
• Removing values that turn out to be estimates (e.g. DX12 benchmarks on pre-DX12 GPUs)

Rules

• Only change a value when a source unambiguously gives the right one for that exact SKU or variant. If sources conflict, document the conflict instead of picking a side.
• Add the evidence URL to source_urls; keep verified as it is.
• Each fix PR lists its changed fields and the unresolved items in the body.

Status (2026-09-27)

Area	Done	Open
Storage recorded as RAM	#257, #279, #281, #293 (~100 records)	5 devices with no source stating RAM
SoC release dates	#287, #289 (182 records)	Kirin tables have no dates; coarse same-year dates
GPU cross-check	#260, #290	49 conflicts reviewed; no supportable fix
Intel CPU cross-check	#263, #266 (150 records)	45 ambiguous slugs
Duplicates	#280, #282 (17 GPU pairs)	Near-duplicates in other categories not yet scanned
Placeholder SoC links	#271 (53 tablet "0" values)	7,077 phone references to 51 generic SoC slugs; needs an external per-device source

Reporting

One comment per batch: what was fixed, with counts and examples, and what stays unresolved.

2026-09-27 batch: self-consistency fixes (#301, #300)

• fix(data): correct storage, battery and display fields from each record's own text #301: 291 records corrected from text already in each record.
  • 259 tablet/watch storage lists that had the RAM size mixed in
  • 2 iPad Pro battery capacities
  • 3 laptop storage values
  • 29 monitor size/resolution/aspect-ratio values
• fix(data): link Galaxy watches to Exynos SoCs and drop soc "0" on watches #300: removed placeholder soc: "0" from watches; mapped Galaxy Watch4–Ultra to Exynos W920/W930/W1000.
• Scoring: laptop and monitor now have domain rules (feat(verify): add laptop and monitor domain scoring TechEngine#102). 107 laptops can now reach green.

Still open, needs sourcing rather than derivation:

• 43 devices whose release date is more than 2 years before their chip's
• 15 tablets/watches whose slug RAM disagrees with ram_gb
• 20 multi-edition tablets whose storage list mixes RAM and storage
