Corrections belong beside the research.
Product facts change and mistakes happen. Material revisions are dated here, while each comparison keeps its own evidence date and source ledger.

No post-publication corrections yet.
Earlier if a major vendor change is observed.
What receives an entry
A material correction changes the meaning of a price, allowance, feature, identity method, retention statement, privacy description, technical instruction, calculation, or recommendation. The entry identifies the affected page, the original meaning, the corrected meaning, the evidence, and the date the revision became public.
Spelling, punctuation, layout, accessibility, and clarity improvements are corrected directly unless they altered a factual claim. Source URLs may be repaired without a material entry when the cited document and supported claim remain the same.
How changing vendor facts are handled
Prices, plan limits, trials, retention, hosting, crawler documentation, and future-feature status receive priority. If a vendor change makes a comparison materially wrong, the page is updated and logged. If a source is temporarily unavailable, the unsupported claim is qualified or removed rather than preserved from memory.
Submission status during the holding phase
There is no public corrections inbox or contact form in the first holding edition. Publishing an address that does not route anywhere would be worse than stating the limitation. Scheduled primary-source reviews remain the active correction mechanism until an independent public channel is configured.
