Modernized Build Toolchain & CI: Upgraded the project to Swift 6.4.1 and transitioned to Ubuntu 24.04 ARM GitHub-hosted runners. This included a significant overhaul of the CI pipeline to use commit SHAs for deployment naming, updated actions/upload-artifact versions, and the implementation of concurrency groups to prevent redundant test runs.
Optimized Lambda Deployment: Replaced the AWSLambdaPackager plugin with a custom, one-pass build script (build-all-lambdas.sh) running within an Amazon Linux 2023 container. This architectural change enables parallel compilation of all handlers in a single graph, bundles OpenSSL statically, and reduces deployment time by eliminating serial per-product container runs.
Dependency Stabilization: Moved from floating dependency requirements to a committed Package.resolved file. This ensures build reproducibility and prevents frequent, unnecessary recompilations of the AWS SDK and ActivityPubCore caused by upstream minor releases.
Reply-Threading & Fetch Hardening (Spec): Developed a comprehensive technical specification for “Step 0” of reply threading. Key architectural decisions include adopting typed remote-fetch schemas, implementing strict content-type validation via middleware, and integrating async-http-client for better transport control.
Security & Reliability Enhancements: Integrated Mastodon’s private-address CIDR list to prevent SSRF attacks and defined a rigorous “test seam” for the ReplyStore to allow in-memory validation of DynamoDB interactions. Added detailed error handling for transport failures and invalid URI redirects.

Implemented “Rung 3” Tooling: Introduced Tape and Cut tools where tape acts as a translucent adhesive that binds objects into groups based on connected components of touches. The Cut tool enables topological separation of these groups and tape strips.
Architectural Grouping Logic: Developed a new grouping system (Group.swift, CanvasGroups.swift) that utilizes a single ObjectGestureCore per group bound in world space with locked scaling, ensuring that group members do not carry individual gestures.
Rigorous Validation Framework: Established a “Skeptic” review standard (SKEPTIC.md) and an Inert-Twin mechanism. This allows features (e.g., INERT_ELASTIC) to be compiled as pass-throughs to verify that tests fail specifically when a feature is disabled, preventing vacuous test passes.
Precision Instrumentation & Spikes: Created a precondition spike to measure drag slope, rotation drift, and release displacement for members within nested coordinate spaces. This included a custom host-side reader to detect “release misses” caused by simgesture stream-playback behavior.
Regression & Provenance Tracking: Integrated a direction-ledger.md to track architectural decisions and restored 22 historical recordings with full SHA256 provenance to ensure consistent A/B testing between main and head builds.
Input Handling Fixes: Resolved a critical bug in CanvasNavigator where the final viewport pose was ignored during .ended gestures, causing the camera to stop short of the actual lift point; updated package-multitouch-handler to version 0.7.0 to unify lift events.
