v1.28.0

Highlights

• Added cached skill-registry refresh on agent startup for Claude Code and OpenCode.
• Enforced parent-orchestrator delegation triggers across SDD orchestrator assets.
• Upgraded the Go baseline to 1.25.10 and aligned CI/release/E2E toolchains.

Details

Agent harness behavior

• Orchestrators now stop monolithic execution once complexity appears: 4+ file exploration, multi-file writes, PR readiness, incidents, long sessions, and adversarial review all route through the safer delegation/review path.
• Solo-agent platforms use equivalent phase-boundary rules when native subagents are unavailable.

Skill registry startup refresh

• Added gentle-ai skill-registry refresh with fingerprint cache support.
• Claude Code installs a SessionStart hook that refreshes the registry best-effort.
• OpenCode refreshes the registry from the installed background-agents plugin.
• Registry writes are atomic, startup refresh avoids mutating .gitignore, and SDD uninstall removes the managed Claude hook.

Toolchain

• Updated go.mod to Go 1.25.10.
• GitHub Actions now use go-version-file: go.mod.
• Ubuntu/Fedora E2E Dockerfiles now install Go 1.25.10.

Collaboration

• Thanks to @mata-2p for opening PR #450 and pushing the Go baseline upgrade. The final release applies the same direction directly on main, updated to the latest Go 1.25 patch release (1.25.10).

Verification

• go test ./...
• Release workflow completed successfully for v1.28.0.
