When `version` is greater than 11 the SDK buckets visitors under the anchored layout; experiences at version 11 or below (and those with a missing or non-numeric version) continue to use the existing packed layout, bit for bit. Under the anchored layout each variation occupies a band anchored to its cumulative position in the allocation space rather than being packed end to end. Raising an experiment's total traffic allocation therefore admits new visitors at each arm's own edge and never relocates a visitor who was already bucketed, and lowering allocation ejects out-of-range visitors without ever flipping a retained visitor to a different arm. Stopped arms and arms with an explicit zero allocation keep their anchor position but receive zero width. The hash, seed, scaling, stored-decision precedence, forced-variation path, and event payloads are unchanged. BREAKING CHANGE: bumps the cross-SDK bucketing contract to v12. Experiences served with `version` greater than 11 are bucketed with the anchored layout, which assigns different variations than the previous packed layout for the same visitor. Experiences at version 11 or below are unaffected. --- .../Bucketing/AnchoredBucketing.swift | 78 ++++++++++++++----- .../Bucketing/BucketingManager.swift | 62 +++++++++++---- .../Experience/ExperienceManager.swift | 12 ++- 3 files changed, 114 insertions(+), 38 deletions(-) diff --git a/Sources/ConvertSwiftSDKCore/Bucketing/AnchoredBucketing.swift b/Sources/ConvertSwiftSDKCore/Bucketing/AnchoredBucketing.swift index 536a883..1e8ac1f 100644 --- a/Sources/ConvertSwiftSDKCore/Bucketing/AnchoredBucketing.swift +++ b/Sources/ConvertSwiftSDKCore/Bucketing/AnchoredBucketing.swift @@ -1,29 +1,31 @@ // Sources/ConvertSwiftSDKCore/Bucketing/AnchoredBucketing.swift -// ANCHORED bucketing layout (qs-01, cross-SDK bucketing contract v12) — Phase 1 / RED SCAFFOLD. +// ANCHORED bucketing layout (qs-01, cross-SDK bucketing contract v12) — Phase 2 / GREEN. // // Selected per experience by `BucketingManager.bucketVersionGated(...)`: `experience.version > 11` // routes here; `version <= 11` / missing / non-numeric stays on the EXISTING packed walk in // `BucketingManager.bucket(...)` (untouched, AC6).

Zero-trace parity gap — the internal `.bucketing` observer event fired unconditionally for sibling/feature-carrier experiences while a preview was active, diverging from the JS oracle (context.ts wraps every SystemEvents.BUCKETING emit in `if (!this._preview)`) and from this PR's own suppression of `.conversion` and `.segments` under preview. Thread a new `emitBucketing: Bool = true` gate from all four ConvertContext entry points (runExperience/runExperiences/runFeature/runFeatures, as `!previewActive`) through ExperienceManager.selectVariation(s) and FeatureManager.evaluate* to the single fire site. Default `true` keeps every other call site and existing behavior unchanged. 2. Redaction regex — anchor the `debug_token` branch with a negative lookbehind `(?` in any position is still fully stripped. 3. Inert-on-bad-input — PreviewDecision.forcedVariation now returns nil for an experience with a nil/empty key or id (instead of degrading to ""), so a degenerate preview target can no longer poison the runExperiences sibling filter; setPreview treats it as bad input (warns, leaves context normal). Tests: extend AC6 zero-trace to assert zero `.bucketing` observer events under preview across experience + feature paths; add regex boundary cases and PreviewDecision empty-key/id cases. Full suite green under ThreadSanitizer (370 passed / 1 skipped / 0 failed), SwiftLint --strict clean, parity + DocC coverage gates pass.

A `convertdemo://…?convert_preview={experienceId}.{variationId}` link is delivered via SwiftUI `.onOpenURL` to `DemoViewModel.applyPreviewLink`, which parses it with the SDK's `PreviewParam.parse` and forces the variation via `ConvertContext.setPreview`, then re-runs experiences so the forced result renders on the Experiences screen. Fully inert on a missing/malformed link. - Info.plist (new): register the `convertdemo` URL scheme. GENERATE_INFOPLIST_FILE can't express CFBundleURLTypes, so switch to a real Info.plist. - project.pbxproj / project.yml: point INFOPLIST_FILE at it (GENERATE_INFOPLIST_FILE=NO), kept consistent so `xcodegen generate` reproduces it. - DemoViewModel+Preview.swift (new): applyPreviewLink + os.Logger diagnostics. - README (new): "Testing experiment-preview deep links" with the simctl steps. Verified end-to-end in the iOS 26 Simulator: openurl → Open → the previewed experience renders its forced variation.
