Value-level data validation gate
`qa:data` now blocks duplicate IDs or slugs, invalid source URLs, bad ISO dates, impossible capacities, scenario ranges outside their defaults, and measured records that no longer map to a model.

Model Data Changelog
A public log of source-backed model-data changes, QA gates, and trust-policy updates.
171 source-linked model recordsEvery model keeps source URLs and confidence visible.
234 unique source URLsModel, scenario, and measured-record sources after duplicates are collapsed.
11 measured recordsOnly attributed third-party measurements are counted here.

Public Change Log
This log tracks changes that affect published model data, source policy, validation, or measured-data handling.
Third-party source labels tightened
Known third-party source hosts are now guarded in `qa:data`: Home Depot and Lowe's PDFs stay retailer sources, while device.report manual mirrors are marked community unless an official source is listed separately.
Fragile source archive workflow added
`qa:source-archive` now tracks PDF, CDN, and manual-mirror source URLs in a manifest so new fragile evidence links are reviewed without committing third-party files to the repo.
Confidence labels tied to source quality
Verified now requires official-source support plus required planning specs. Source-linked records with important gaps stay estimated instead of being promoted.
Measured library v1 published
The first attributed third-party measured AC capacity records are public. Estimate-vs-measured deltas are display math only, never stored as measured data.
Unknown usable capacity stays unknown
Model pages stopped showing derived usable-capacity rows when the source record has no usable Wh value. The calculator may estimate usable energy, but the model spec table does not.
Maintenance runbook added
The data maintenance workflow now documents validation, source checks, changelog review, and the rule that computed values must not be re-labeled as source facts.
What Gets Logged
The changelog is intentionally narrow so it stays useful instead of becoming an internal issue list.
Source-policy changes
Any change that alters verified, estimated, unknown, or measured labels belongs here.
Validation gates
Build-time checks that can block bad source data are visible because they affect trust.
No guessed specs
New model specs, capacities, or measurements are not invented for the changelog.
