Tradour explained
A canonical outcome is the versioned primary measure Tradour approves for a research question. It fixes timing, calendar, price fields, horizon, direction and edge cases before comparison.

Several rulers with different zero points can produce different answers. Choosing, documenting and versioning one official ruler makes results comparable and auditable.
Now put that into markets
For BSP earnings research, the intended outcome uses legitimate market sessions around when information became public. Missing auditable prices or timestamps leave it unavailable.
Definitions specify market calendar, cut-off, price source, corporate actions, neutral outcomes and exclusions. Method changes create a new outcome version.
Check definition ID, version, source coverage and availability state. Never substitute a convenient proxy without changing the label.
Canonical means governed and reproducible, not objectively perfect. A revised definition must not overwrite results produced by the old one.
