boundary-fit consults the show-blind ident duration (≤~4s one-directional skew inside a show)

[genwave-radio]

🎚️ The accepted skew (pinned, deliberate — this issue is the revisit ticket)

T250 re-keyed RollingPatterDurationEstimator's Exact memo to (voice, showName) so mixed-show templated-ident durations never cross-contaminate. The WRITE side stamps per-show; the READ side (Orchestrator.BuildBoundaryFit) still calls the 3-arg show-blind overload, so inside a show the fit can consult the plain ident's duration at Exact confidence while the airing will render the longer show line — up to ~4s one-directional under-estimate inside a 30s tolerance band. The (voice, null) bucket stays unpolluted (the important half), and worstConfidence widens the band whenever any other kind in the fit is non-Exact.

📍 In-code notes

• src/GenWave.Orchestration/Orchestrator.cs ~BuildBoundaryFit (the read-side call)
• tests/GenWave.Orchestration.Tests/Specs/Gh253_PatterDurationEstimator.cs — the deliberate pin; its "no show context to offer" comment is inaccurate (the resolver is one expression away) and should be corrected with the fix

🔧 Fix shape

Pass scheduleResolver?.TryGetCurrent()?.Show?.Name into the 4-arg Estimate overload at the fit site; flip the pin to assert show-aware reads.
