Follow-up to #3205.

#3205's remaining Platform(Go) blocker was TestMCPPluginDeliveryContract_MCPServerAdaptorWritesMcpServers failing because it still asserted the legacy /configs/.claude/settings.json write. After runtime#172 (6eefd27) moved mcpServers delivery to the runtime-agnostic MCP-wiring PORT, that file assertion was stale and false-greened direct-write regressions.

Changes:

• contracts/mcp-plugin-delivery.contract.json: drop legacy top-level settings_path/key/consumer; keep the PORT descriptor, symbol names, and per-runtime native surfaces.
• workspace-server/internal/handlers/mcp_plugin_delivery_contract.go: remove legacy fields from the Go struct and MatchesSSOT; add Consumers array to match JSON.
• workspace-server/internal/handlers/mcp_plugin_delivery_contract_test.go: rename TestMCPPluginDeliveryContract_MCPServerAdaptorWritesMcpServers → TestMCPPluginDeliveryContract_MCPServerAdaptorRegistersMcpServerViaPort; assert the adaptor calls InstallContext.register_mcp_server with the molecule-platform descriptor; stop reading back .claude/settings.json.

Verified locally against runtime 6eefd27:

MOLECULE_WORKSPACE_RUNTIME=/workspace/molecule-ai-workspace-runtime go test ./internal/handlers/
ok  git.moleculesai.app/molecule-ai/molecule-core/workspace-server/internal/handlers  40.634s

Fixes #3205 (Platform(Go) follow-up).

Follow-up to #3205. #3205's remaining Platform(Go) blocker was `TestMCPPluginDeliveryContract_MCPServerAdaptorWritesMcpServers` failing because it still asserted the legacy `/configs/.claude/settings.json` write. After runtime#172 (6eefd27) moved mcpServers delivery to the runtime-agnostic MCP-wiring PORT, that file assertion was stale and false-greened direct-write regressions. Changes: - `contracts/mcp-plugin-delivery.contract.json`: drop legacy top-level `settings_path`/`key`/`consumer`; keep the PORT descriptor, symbol names, and per-runtime native surfaces. - `workspace-server/internal/handlers/mcp_plugin_delivery_contract.go`: remove legacy fields from the Go struct and `MatchesSSOT`; add `Consumers` array to match JSON. - `workspace-server/internal/handlers/mcp_plugin_delivery_contract_test.go`: rename `TestMCPPluginDeliveryContract_MCPServerAdaptorWritesMcpServers` → `TestMCPPluginDeliveryContract_MCPServerAdaptorRegistersMcpServerViaPort`; assert the adaptor calls `InstallContext.register_mcp_server` with the molecule-platform descriptor; stop reading back `.claude/settings.json`. Verified locally against runtime 6eefd27: ``` MOLECULE_WORKSPACE_RUNTIME=/workspace/molecule-ai-workspace-runtime go test ./internal/handlers/ ok git.moleculesai.app/molecule-ai/molecule-core/workspace-server/internal/handlers 40.634s ``` Fixes #3205 (Platform(Go) follow-up).

APPROVED on e95aa01b.

Reviewed the live diff against current main: exactly three intended files changed (core contract JSON, contract struct/MatchesSSOT, and contract tests). Removing the legacy top-level settings_path/key/consumer fields does not drop a still-needed assertion: the active delivery contract is now the PORT descriptor plus per-runtime native surfaces in runtimes. The per-runtime claude_code/codex/gemini_cli/hermes settings remain pinned, and the Codex regression test now uses contract.Runtimes["claude_code"].SettingsPath for the misroute guard instead of the removed top-level Claude path.

The renamed producer test genuinely validates PORT routing and is not false-green: it installs the real MCPServerAdaptor, binds a spy as InstallContext.register_mcp_server, then asserts exactly one recorded call with name molecule-platform, command molecule-mcp, and MOLECULE_MCP_MODE=management. A regression that directly writes .claude/settings.json would bypass the spy and leave recorded empty, so this catches the #3159/#3205 failure mode. The old .claude read-back was the stale assertion and is correctly removed from this producer contract test.

5-axis: correctness/robustness improve by aligning the contract to runtime#172 PORT delivery; security/performance risk is negligible because this is test/contract metadata only; readability improves by removing contradictory legacy fields. CI note: CI / Platform (Go) is green on e95aa01b. CI / all-required was still pending when fetched, with visible red review-gate contexts and the known mcp-plugin-delivery-contract-drift follow-up explicitly non-BP for this coordinated update.

APPROVED on e95aa01b. 5-axis review: diff-vs-main is clean and limited to the MCP plugin delivery contract JSON, its Go mirror, and the contract tests. Legacy top-level settings_path/key/consumer fields are removed from the contract surface while per-runtime native surfaces remain pinned under runtimes, including claude_code and codex implemented entries plus declared todo runtimes. MatchesSSOT still pins entry shape, producer, server name, PORT hook/impl/present probe, descriptor, and per-runtime settings/table/renderers. The renamed adaptor test now asserts the real MCPServerAdaptor calls InstallContext.register_mcp_server with the molecule-platform descriptor, which is the load-bearing PORT assertion; it no longer false-greens on a legacy direct .claude/settings.json write. Codex routing still asserts the TOML native surface and absence of Claude settings. No production/security/secret-handling regression found. Platform(Go) is green; known mcp-plugin-delivery-contract-drift red is non-BP sequencing until template/runtime canonicals are coordinated.

chore(contract): remove legacy top-level MCP delivery fields #173

test(handlers): MCPServerAdaptorRoutesThroughPort — assert PORT, deny direct .claude write ... bf58b55610

Per Researcher spec for #3205: replace the failing
TestMCPPluginDeliveryContract_MCPServerAdaptorWritesMcpServers with
TestMCPPluginDeliveryContract_MCPServerAdaptorRoutesThroughPort. The new test
exercises the real MCPServerAdaptor against runtime 6eefd27 and asserts:

1) ctx.register_mcp_server is called exactly once with (molecule-platform, spec).
2) The adaptor did NOT directly create /configs/.claude/settings.json.

The spy no longer renders the legacy Claude file, so a direct-write regression
fails on both the empty recorder and the leftover file. The existing codex
e2e sub-test continues to assert ~/.codex/config.toml is produced and
.claude/settings.json is absent on a codex runtime.

Verified: go test ./internal/handlers/ passes against runtime 6eefd27.

APPROVED on bf58b556. Fresh 5-axis review of the keep-legacy standalone target: diff is limited to mcp_plugin_delivery_contract_test.go; contracts/mcp-plugin-delivery.contract.json is unchanged and keeps legacy top-level settings_path/key/consumer while retaining PORT and runtimes metadata, so this does not re-break runtime/template drift. The renamed MCPServerAdaptorRoutesThroughPort test is stronger than the old file-read assertion: it installs the real MCPServerAdaptor with an InstallContext.register_mcp_server spy that records the molecule-platform descriptor and deliberately does not render, then asserts the legacy .claude/settings.json file is not created. That catches both a missing PORT call and a direct-write regression. No production code or secret/auth behavior changed; no performance concern. Platform/CI were pending in the status API during my fetch after reset, but the code/test change itself is clean; merge should still wait for required green gates and the second genuine approval.

APPROVED on bf58b55610.

5-axis review:

• Correctness: this reset head keeps the legacy top-level contract fields (settings_path/key/consumer), so it does not re-break runtime/template consumers or contract drift. The only changed file is workspace-server/internal/handlers/mcp_plugin_delivery_contract_test.go.
• Robustness: TestMCPPluginDeliveryContract_MCPServerAdaptorRoutesThroughPort now binds a register_mcp_server spy that records the PORT call but deliberately does not render. A direct .claude/settings.json write regression would leave the recorder empty and create the legacy file, so the test would fail rather than false-green.
• Security: no production code or secret-handling path changed. The test hardens the contract against bypassing the runtime-agnostic MCP delivery PORT.
• Performance: test-only change; no runtime performance impact.
• Readability: the renamed test and comments clearly distinguish legacy top-level contract compatibility from the required PORT routing behavior.

CI: CI / Platform (Go) and CI / all-required are success on bf58b5561. Security-review and reserved-path-review are green after review-trigger reruns; remaining pending staging SaaS contexts are outside this test-only contract target.
