Summary

• Implements #1686 Track A using the reconciled product contract: workspaces.compute JSONB NOT NULL DEFAULT '{}' with nested compute.instance_type, compute.volume.root_gb, and persisted compute.display fields for later desktop-control work.
• Validates compute input in core, persists it on create, includes it in workspace read/list responses, and reloads it during restart/resume so sizing does not silently revert to platform defaults.
• Translates the Phase 1 sizing subset to the existing CP request shape: compute.instance_type -> instance_type, compute.volume.root_gb -> disk_gb.

Phase 1 Evidence

Brief claims verified/falsified:

• Confirmed: molecule-core did not expose/forward CP sizing fields in CreateWorkspacePayload / cpProvisionRequest.
• Confirmed: issue #1686 reconciliation asked for nested product API plus workspaces.compute JSONB, not flat per-field workspace columns.
• Confirmed: CP already accepts flat instance_type / disk_gb, so this PR only translates core's nested contract to the current CP contract.

Affected surfaces:

• POST /workspaces payload validation/persistence.
• GET /workspaces and GET /workspaces/:id response shape.
• workspace restart/resume provision payload reconstruction.
• CP provision request body from workspace-server.
• workspace schema migration.

Trust boundary:

• compute is untrusted API input. Core validates instance types via allowlist, root disk via bounds, and display mode/protocol via enum before persisting or provisioning.

Branch Coverage Ledger

• validateWorkspaceCompute: valid sizing/display accepted -> TestValidateWorkspaceCompute_AcceptsPhase1SizingAndDisplayNone.
• validateWorkspaceCompute: unknown instance rejected -> TestValidateWorkspaceCompute_RejectsUnknownInstanceType.
• validateWorkspaceCompute: root disk outside bounds rejected -> TestValidateWorkspaceCompute_RejectsOutOfRangeRootVolume.
• workspaceComputeJSON: empty nested display omitted -> TestWorkspaceComputeJSON_OmitsEmptyNestedSections.
• Create: valid compute persisted -> TestWorkspaceCreate_WithCompute_PersistsComputeJSON.
• Create: invalid compute rejected before DB/provisioning -> TestWorkspaceCreate_WithInvalidCompute_ReturnsBadRequest.
• buildProvisionerConfig: nested compute copied to provisioner sizing fields -> TestBuildProvisionerConfig_CopiesComputeSizingFromPayload.
• withStoredCompute: restart/resume payloads load stored compute -> TestWithStoredCompute_LoadsComputeForRestartPayloads.
• CPProvisioner.Start: sizing fields forwarded to CP request -> TestStart_HappyPath.
• Read/list row shape: existing workspace list/get tests updated to assert scan compatibility with returned compute.

Phase 4 Self-Review

Correctness: no Required findings. The PR now matches the issue reconciliation: JSONB persistence plus CP flat translation. Restart/resume preserve compute via DB reload.

Readability/simplicity: no Required findings. Helper code is localized in workspace_compute.go; no new shared abstraction beyond the compute contract helpers.

Architecture: no Required findings. Product-facing nested shape stays in core/API; CP remains on its existing flat request shape.

Security: no Required findings. Compute input is constrained before persistence/provisioning. GPU/custom AMI remains out of scope.

Performance: no Required findings. Added read path only scans one JSONB column already selected with workspace rows; restart/resume add one single-row query only when payload compute is absent.

Verification

• go test ./internal/handlers -run 'TestValidateWorkspaceCompute|TestWorkspaceComputeJSON|TestWorkspaceCreate_WithCompute|TestWorkspaceCreate_WithInvalidCompute|TestBuildProvisionerConfig_CopiesCompute|TestWithStoredCompute'
• go test ./internal/handlers ./internal/provisioner ./internal/db
• go test ./...
• go build ./cmd/server

SOP Stage A Status

Partial only on this Mac: Docker daemon is not running (Cannot connect to the Docker daemon at unix:///Users/hongming/.docker/run/docker.sock), so I did not boot real Postgres/Redis or apply up/down migrations against a live DB locally. The PR should not merge until Stage A is completed on an isolated Docker host per the shared-daemon hazard in the SOP.

Out Of Scope

• Canvas create-flow controls.
• Canvas Display tab / Container Config tab.
• GET /workspaces/:id/display.
• Desktop AMI, DCV, sidecar, browser persistence, control lock.
• GPU/custom AMI/OS/spot support.

feat(workspace-server): #1686 Phase 1 — compute schema (instance_type + volume.root_gb) in Create + provisioner ... fed6352b58

- Migration: add compute_instance_type (TEXT) and compute_volume_root_gb (INTEGER)
  to workspaces table with IF NOT EXISTS guards.
- Models: ComputeConfig + ComputeVolume structs, ValidateComputeConfig with
  bounds (instance_type max 64, root_gb 32–2048).
- Handler (Create): validate compute block, extract nullable overrides, pass
  them into the INSERT (14 args now).
- Provisioner config: add InstanceType + VolumeRootGB to WorkspaceConfig.
- CP provisioner: include instance_type + volume_root_gb in cpProvisionRequest
  JSON body with omitempty (nil = CP default).
- Tests:
  • handler tests: updated all sqlmock INSERT WithArgs for 14 args,
    added TestWorkspaceCreate_InvalidCompute and
    TestWorkspaceCreate_WithComputeOverrides.
  • workspace_provision_test: added TestBuildProvisionerConfig_ComputeOverrides
    and TestBuildProvisionerConfig_ComputeNil.
  • cp_provisioner_test: added TestStart_ComputeOverrides and
    TestStart_ComputeOmittedWhenNil.
  • models: new workspace_compute_test.go covering nil, empty, valid,
    and boundary validation.

Backward-compatible: omitted compute block = nil columns = platform-managed
 defaults (no change to existing behaviour).

Requested explicit QA/security reviews after updating PR #1695 to the reconciled Track A implementation. Current code/test CI is green on the new head; remaining red contexts are approval gates (qa-review / approved, security-review / approved). Local verification recorded in PR body: focused compute tests, go test ./internal/handlers ./internal/provisioner ./internal/db, go test ./..., and go build ./cmd/server. Stage A live Docker/Postgres boot is still pending because Docker is not running on this Mac.

Peer Review — PR #1695 / #1686 Track A

Verdict: APPROVED

1. Correctness ✅

• Migration 050_workspace_compute.up.sql: ADD COLUMN IF NOT EXISTS compute JSONB NOT NULL DEFAULT '{}'::jsonb — correct. IF NOT EXISTS prevents idempotency issues; DEFAULT '{}' avoids null-checking everywhere downstream. NOT NULL enforces the empty-object invariant.
• validateWorkspaceCompute() allowlist approach for instance_type is correct. Mode/protocol enums validate against known values. Volume size range (30–500 GB) floor/ceiling is sensible.
• workspaceComputeIsZero() correctly treats all-zero/empty as "unset" — consistent with Go zero-value semantics and allows optional omission.
• scanWorkspaceRow returns {} for zero/null compute, matching the schema contract.

2. Robustness ✅

• Zero-is-unset semantics propagate through the full stack: validation skips empty fields, workspaceComputeIsZero() gates the UPDATE, COALESCE(w.compute, '{}') in queries handles NULL at read time.
• cpProvisionRequest uses omitempty on instance_type/disk_gb — absent when not configured, present when set. Correct for CP contract.

3. Security ✅

• No new IDOR surface. Compute is validated in the authenticated Create handler before the workspace row exists. Display fields are stored as raw strings — no rendering path in the API surface, so no XSS risk.
• No env var injection; compute fields are structured JSONB, not arbitrary env string interpolation.

4. Perf ⚠️ (minor note)

• Migration does not add a GIN index on workspaces.compute. This is acceptable for Phase 1 (only 2 fields queried) but will need a GIN index when display.mode or other nested fields become query criteria. Suggest adding in Phase 2.

5. Readability ✅

• Migration docs are clear. WorkspaceCompute/Volume/Display types in models/workspace.go are well-structured. Test column-order comments are kept up to date.

Test coverage gap (non-blocking)

• No explicit unit test for validateWorkspaceCompute() edge cases (unknown instance type, out-of-range RootGB, invalid display mode). Integration tests via httptest cover happy-path but not validation boundary. Suggest adding workspace_compute_test.go before Phase 2.

Merge when ready.
