GitHub native stack

Stack #4080 targets develop, in order: #4072 → #4074 → #4076 → #4078 → #4079. All five PRs remain Draft. The stack is registered with GitHub, not represented only by titles or description links.

#4072 combines the contracts formerly split into #4071 with the TOML catalog/reader. #4071 is closed as superseded; its commits remain in #4072. No product commits were rewritten for this consolidation.

Purpose

Persist resolved model outlet snapshots in existing model_record_t, without recomposing TOML when loading a saved outlet.

Changes

• Add nullable capability and parameter columns, protocol/schema versions and configuration revision through a new versioned SQL migration. No atomic profile tables.
• Store each configuration value in one place; preserve zero, false, omitted values and explicit JSON null. Restore integer sampling schemas correctly from PostgreSQL FLOAT columns.
• Encode and validate the remaining rules, instruction mapping, binding versions and provenance in bounded JSON. Credentials stay in existing credential columns and are represented by references in runtime snapshots.
• Add tenant-scoped create/read/update operations with atomic optimistic revision checks, soft-delete filtering, caller-owned transactions and sanitized database exceptions.
• Keep existing model CRUD routes unchanged. New persistence functions are available for the upcoming unified onboarding service.

Verification

• Local traditional UT: 761 passed across SDK model_service and existing/new backend model database tests.
• Ruff, diff check and complete formal asset implementation validation passed.
• MOP-D3-001: 3 real PostgreSQL integration tests passed; committed restoration, transaction ownership, stale writers, tenant/deletion isolation, rollback and sanitized SQL failure.
• MOS-D5-001: 2 real PostgreSQL deployment tests passed; legacy value preservation, actual types/defaults/comments, idempotence, rollback and recovery.
• MPC-D1-001: composition regression passed.
• Clean nexent-test snapshot restored, linked worktree mounted natively; main/web/mcp images built; infrastructure/application/supabase deployed using repository scripts.
• Installed SDK source hashes, catalog, codecs and FLOAT restoration checked in the built main image. Required test accounts and service health passed. Nexent homepage loaded in the built-in browser.

Scope and remaining work

Draft member of native Stack #4080, based on #4078. This slice does not claim complete legacy outlet data migration, new onboarding/session APIs, provider transport adapters, NativeAgent or new UI. Those remain part of the approved plan. Unit, main, MCP and data-process CI workflows passed. Codecov PR report: 99.67267% patch coverage.

Superseded by #4082 to reduce review overhead. All commits are already present in that consolidated Draft PR; no code or verification evidence has been discarded. Native GitHub Stack #4086 now contains #4078 → #4082 → #4083.
