Phase 5 Execution Checkpoint

Created: 2026-02-06 Reason: Context limit reached during Wave 2 execution

Current State#

Branch: gsd/phase-05-json-nullable-empty Phase: 5 of 11 (JSON - Nullable & Empty) Plans: 4 total

Wave Status#

Completed Plans#

05-01: Annotation Infrastructure ✓#

• Commits: e0681c7, 30c0efb, dc2dfb5
• Summary: .planning/phases/05-json-nullable-empty/05-01-SUMMARY.md
• Added EmptyBehavior enum and nullable/empty_behavior proto extensions (50013, 50014)
• Created internal/annotations/nullable.go and internal/annotations/empty_behavior.go
• All tests passing

Partial Work (Uncommitted)#

The agents made partial progress before rate limiting. Files created but NOT committed:

httpgen (compiles!):

• internal/httpgen/nullable.go (6183 bytes) ✓
• internal/httpgen/empty_behavior.go (8294 bytes) ✓
• internal/httpgen/generator.go (modified)

Still needed:

• internal/clientgen/nullable.go (copy from httpgen)
• internal/clientgen/empty_behavior.go (copy from httpgen)
• internal/clientgen/generator.go (update)
• internal/tsclientgen/types.go (update for T | null)
• internal/openapiv3/types.go (update for type arrays and oneOf)
• Test protos: nullable.proto, empty_behavior.proto
• Golden files for all generators

Incomplete Plans#

05-02: Nullable Primitives (Wave 2)#

• Agent ID: af785c9
• Status: PARTIAL - httpgen nullable.go created, compiles
• Remaining: clientgen, tsclientgen, openapiv3, test protos, golden files

05-03: Empty Object Handling (Wave 2)#

• Agent ID: acbc6fc
• Status: PARTIAL - httpgen empty_behavior.go created, compiles
• Remaining: clientgen, openapiv3, test protos, golden files

05-04: Cross-Generator Consistency (Wave 3)#

• Status: Not started (depends on 05-02, 05-03)
• Objective: Validate consistency across all generators

IDE Diagnostics Note#

IDE shows errors for http.EmptyBehavior, http.E_Nullable, etc. - these are stale diagnostics (per MEMORY.md). The code compiles and tests pass. Always verify with go build and go test.

Resume Instructions#

1. Check what 05-02 and 05-03 agents partially completed:

   ls -la internal/httpgen/nullable.go internal/httpgen/empty_behavior.go 2>/dev/null
   ls -la internal/clientgen/nullable.go internal/clientgen/empty_behavior.go 2>/dev/null
   git status --short

2. If files exist, verify they compile:

   go build ./internal/httpgen/... ./internal/clientgen/...

3. Resume incomplete plans or re-execute them if no progress was made

4. After Wave 2 complete, execute Wave 3 (05-04)

5. After all plans complete, run verification and update ROADMAP.md
