Todo 4 Category Resolution Repair 1 Evidence

WHAT WAS TESTED

• RED regression suite: bun test packages/senpi-task/src/category
  • Artifact: red-category-tests.log
  • Exit: red-category-tests.exit = 1
  • Scenarios: hardcoded quick fallback to anthropic/claude-haiku-4-5, hardcoded ultrabrain fallback to google/gemini-3.1-pro, system default fallback, tools carry-through, malformed registry entry, prototype-shaped category names, custom description preservation.
• Focused GREEN suite: bun test packages/senpi-task/src/category
  • Artifact: category-tests.log
  • Exit: category-tests.exit = 0
• Package suite: bun test packages/senpi-task --bail
  • Artifact: senpi-task-tests.log
  • Exit: senpi-task-tests.exit = 0
• Type gate: bun run typecheck
  • Artifact: typecheck.log
  • Exit: typecheck.exit = 0
• Manual data-surface QA: bun run packages/senpi-task/scripts/manual-category-qa.ts
  • Artifact: manual-category-qa.log
  • Exit: manual-category-qa.exit = 0
  • Scenarios: happy ultrabrain, disabled overlay, selected unavailable model, hardcoded quick fallback-chain success, system default success, malformed registry typed failure, prototype-name typed failure.
• Runtime OpenCode import guard: scoped rg over Todo 4 source.
  • Artifact: guard-no-omo-opencode-imports.log
  • Exit: guard-no-omo-opencode-imports.exit = 0
• Local 7-step order guard: resolveModelForDelegateTask must be present; local model-order helpers/prose must be absent.
  • Artifact: guard-no-local-model-order.log
  • Exit: guard-no-local-model-order.exit = 0
• No-excuse TypeScript guard: bun run packages/shared-skills/skills/programming/scripts/typescript/check-no-excuse-rules.ts packages/senpi-task/src/category packages/senpi-task/scripts/manual-category-qa.ts packages/senpi-task/src/index.ts
  • Artifact: no-excuse-ts-guard.log
  • Exit: no-excuse-ts-guard.exit = 0
• Changed-source LOC check.
  • Artifact: loc-check.log
  • Exit: loc-check.exit = 0

WHAT WAS OBSERVED

• RED output failed for the intended pre-fix blockers:
  • hardcoded fallback-chain regressions returned model_unavailable;
  • tools was undefined;
  • malformed registry [null] threw on model.provider;
  • prototype-shaped category names returned model_unavailable;
  • custom description was dropped.
• GREEN focused suite passed 12 tests with 48 assertions.
• Manual QA output includes:
  • hardcodedFallback.kind: "resolved" with anthropic/claude-haiku-4-5;
  • systemDefault.kind: "resolved" with local/system-default;
  • malformed.kind: "model_unavailable" and availableModels: [];
  • prototypeName.kind: "not_found".
• Guard output confirms no runtime omo-opencode imports and no local model-order helper calls in Todo 4 category source.
• No-excuse guard reported no violations in 12 files.
• LOC check shows all changed source files are below 250 pure LOC.

WHY IT IS ENOUGH

The RED/GREEN pair directly covers each Gate B blocker with behavior tests rather than static import overfit. The resolver still delegates model ordering to delegate-core; Senpi owns only the category fallback data table and adapter mapping. Manual QA drives the exported resolver through the same in-memory registry surface later task spawning will use, including success and typed failure cases. Typecheck, package tests, no-excuse, import guards, local-order guard, and LOC checks cover integration and maintainability risk.

WHAT WAS OMITTED

• No OpenCode or Codex harness QA was run because this repair touched only packages/senpi-task category adapter code and evidence.
• No real user config, network, filesystem outside this worktree, or secret-bearing logs were used.
• The fallback-chain table is locally mirrored because adding @oh-my-opencode/model-core to packages/senpi-task/package.json is outside the allowed edit scope for this repair.
