[doctrine-platform-pillars] Fleet conformance gaps

[shtse8]

Align repository with Sylphx platform pillars (ADR-167)

Repository: SylphxAI/codec
Lifecycle/Layer: active / foundation
Doctrine: https://github.com/SylphxAI/doctrine
Decision: SylphxAI/doctrine ADR-167-boundary-contract-stack-and-platform-pillars

This issue is machine-generated from a fleet conformance audit. Work in verified slices — one boundary or pillar at a time. Full-repo rewrite in one PR is not required; incremental migration with green CI is.

Findings

• [medium] project-manifest — Project manifest status is PARTIAL; expose PROJECT.md, .doctrine/project.json, and a root agent adapter.
• [medium] project-manifest — boundaries.publicSurfaces[2].type has unknown value 'package'
• [medium] project-manifest — boundaries.publicSurfaces[3].type has unknown value 'package'
• [medium] project-manifest — boundaries.publicSurfaces[5].type has unknown value 'package'
• [medium] project-manifest — boundaries.publicSurfaces[6].type has unknown value 'package'
• [medium] project-manifest — boundaries.publicSurfaces[11].type has unknown value 'test'
• [medium] project-manifest — boundaries.allowedDependencies[1].direction has unknown value 'upstream-shared'
• [medium] project-manifest — delivery.ciModel has unknown value 'repo-ci-with-groundatlas'
• [medium] project-manifest — adoption.status has unknown value 'adopted'
• [high] boundary-contract — No Protobuf+Buf contract SSOT detected (buf.yaml, buf.gen.yaml, or .proto tree). Cross-boundary APIs should use Protobuf+Buf per SylphxAI/doctrine ADR-167-boundary-contract-stack-and-platform-pillars.

Target state (ADR-167)

• Rust backends/services; TypeScript web UI; Dart/Flutter mobile UI.
• Protobuf + Buf as cross-boundary contract SSOT.
• Connect/gRPC for app↔service; OpenAPI-derived REST for public edge.
• PROJECT.md, .doctrine/project.json, and root AGENTS.md/CLAUDE.md.

Suggested slice order

1. Add or fix project manifest + agent adapter (zero-knowledge handoff).
2. Introduce .proto + Buf; derive clients; keep existing API as compatibility shim.
3. Migrate backend paths to Rust in boundary-sized slices.
4. Point web/mobile clients at generated Connect/gRPC clients.
5. Remove hand-maintained duplicate contracts once codegen gates are green.
