Severity: MEDIUM

The problem

docs/circa-spec.md §10.6 defines cross-signal confidence: boost when signals agree, reduce when
they conflict, cap derived evidence. Only per-row AI confidence exists; nothing computes a combined
score.

Consequence: the spec'd photo browser sort "by confidence ascending" — the main way to find the
photos that need attention — is impossible. The browser API currently supports only status and
album_id filters against the spec's date-range, confidence, and flag filters.

Scope

Implement the combined confidence computation per §10.6.
Store it as a projection field on Photo so sorting and filtering are cheap, updated through the
projection service.
Expose confidence sort and filter on the browser.
Feed the "single best suggestion" needed by the constraint explanation UI (#20) and any guided
review mode.
Include it in the rebuild fold (#79) so it cannot drift.

Done when

Every photo has a combined confidence score derived from its active evidence
Agreement raises it and conflict lowers it, per spec
The browser can sort ascending by confidence
The score is recomputed when evidence or decisions change
