Upstream Bering sync checkpoint

The current Sheaft main line is app-level synced against Bering v0.3.4 while keeping the same accepted Bering schema contract pins.

• Bering release/package: https://github.com/MB3R-Lab/Bering/releases/tag/v0.3.4
• Bering release manifest asset: release-manifest.json (sha256:d7f4b3d61ff8e36bd370dadd351e51a2b2803677ae12a5e0fbb81faacfd01e20)
• Bering contracts pack asset: bering-contracts_0.3.4.tar.gz (sha256:3865a8e7152c8a383f34d99334bc392cfd0ec793325b530d392723f67839ddbf)
• Sheaft sync commit: 64ea26a1bb33cba77fea0b6fcdf07cb883d072a3
• compatibility-manifest.json records tested_bering_app_versions: ["v0.3.4"]
• Accepted schema contract pins remain io.mb3r.bering.model@1.0.0, io.mb3r.bering.snapshot@1.0.0, io.mb3r.bering.model@1.1.0, and io.mb3r.bering.snapshot@1.1.0
• Sync CI passed: ci-template-smoke run 26717682013, schema-contract run 26717682015, and release-dry-run run 26717682014

Completed Trustability And Explainability Steps

• R4.1 Public benchmark suite for Sheaft-on-Bering is closed. make benchmark-slice runs the fixed public slice from benchmarks/fixed-slice/manifest.json.
• R4.2 Quality metrics for Sheaft-on-Bering is closed. The slice emits quality-report.json with repeatability and quality checks.
• R4.3 Negative results and applicability boundaries / do-not-trust signals is closed. docs/assumptions-and-limitations.md publishes detector IDs, manual heuristics, severity, remediation, and the future report field shape.
• R9.1 Why mode for Bering-based gate decisions is closed. Reports include policy_evaluation.reasons; summary.md includes Why; sheaft gate/run --why prints decision causes.

Current Priority Backlog

1. R9.2 Debugging toolkit for contract and path analysis
2. R9.3 Dependency-level explanations for posture diffs and serve mode
3. R3.4 Scalability on large Bering snapshots
4. R5.3 Chaos triage from Bering-driven risk outputs
5. R1.3 Remaining resiliency interpretation gaps (fallback/rate-limit)
6. R7.3 Pilot-to-production playbook (Bering -> Sheaft)

Product Capability Ordering

The next roadmap emphasis remains explainability and operator actionability before broadening the analysis surface. Pluginization remains useful, but it should follow debugging, dependency-level explanation, and benchmark scale work that make current gate decisions defensible.
